By the way, when the door opening is opened when a passenger gets in and out of the vehicle, foreign substances such as mosquitoes may enter the vehicle compartment through the door opening. Mosquitoes are pests that carry infectious diseases such as malaria and dengue fever. Therefore, if mosquitoes invade the vehicle interior, there is a risk of interfering with the safety, security, and comfort of the interior space of the vehicle.

By using the dust reduction device disclosed in Patent Literature 1, it is possible to prevent foreign matter such as mosquitoes from entering the passenger compartment through the opened door opening.

However, the dust reduction device of Patent Literature 1 requires a dedicated duct to guide air to the plurality of air outlets, so it is difficult to mount on a vehicle. As a result of detailed studies by the inventors, the above was found.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to improve the mountability of an air blowing device capable of suppressing entry of foreign matter into a vehicle interior through a door opening.

In order to achieve the above object, the air blowing device according to claim 1 comprises:
An air blowing device mounted on a vehicle (80) having door openings (82, 84) provided in a vehicle body (81) and doors (86, 88) for opening and closing the door openings,
an air conditioner unit (11) having a blower (14) and performing air conditioning in the passenger compartment;
While the door opening is opened by the door, the blower is operated, and the air flowed by the blower is transferred to the air conditioning ducts (39, 40, 41, 42, 431, 432, 441, 442), and a control device (12) that blows from a predetermined outlet (Ps) that is connected to the air conditioning duct and provided in the vehicle interior,
The predetermined air outlet blows air from the interior side of the door opening to the exterior side of the vehicle through the door opening,
The air-conditioning duct also circulates the conditioned air that flows out from the air-conditioning unit when the air-conditioning unit air-conditions the vehicle interior.
Inside the air conditioner unit, a first air passage (19b) for allowing the air blown by the blower to pass through the heat exchanger (24) and a first air passage (19b) are provided in parallel with the first air passage to exchange heat with the air blown by the blower. A second air passage (19c) is formed to bypass the vessel and flow,
The air conditioner unit has a passage opening/closing device (26) for opening and closing the second air passage,
The control device causes the passage opening/closing device to open the second air passage when blowing air from the predetermined outlet while the door is open.

As described above, while the door of the door opening is open, the control device operates the blower and causes the air blown by the blower to be blown out from the predetermined outlet through the air-conditioning duct. The predetermined air outlet blows out air from the inside of the vehicle compartment to the outside of the vehicle compartment through the door opening while the door is open. Therefore, when a foreign object such as a mosquito attempts to enter the vehicle through the door opening while the door is open, the foreign object is blown away from the vehicle by the air flow from the predetermined outlet. In this way, it is possible to prevent foreign matter from entering the vehicle interior through the door opening while the door is open.

The air-conditioning duct to which the predetermined outlet is connected also circulates the conditioned air that flows out from the air-conditioning unit when the air-conditioning unit air-conditions the vehicle interior. Therefore, a dedicated duct is not required for blowing air from a predetermined outlet for the purpose of suppressing the intrusion of foreign matter into the vehicle interior, and the air conditioning duct used for air conditioning in the vehicle interior is diverted. It is possible to Therefore, it is possible to improve the mountability of the air blowing device on the vehicle.

In other words, the hot air passage 19b is a first air passage for allowing the air blown by the blower 14 to pass through the heater core 24. As shown in FIG. In other words, the bypass passage 19c is a second air passage that is provided in parallel with the hot air passage 19b and allows the air flowed by the blower 14 to bypass the heater core 24. As shown in FIG.

The air mix door 26 is a passage opening/closing device that opens and closes the hot air passage 19b and the bypass passage 19c. The air mix door 26 is configured as a rotating door that rotates, for example, like an arrow Dam.

Specifically, the air mix door 26 can continuously increase or decrease the opening degree of the hot air passage 19b and the opening degree of the bypass passage 19c. The air mix door 26 adjusts the air volume ratio between the air volume of the hot air passage 19b and the air volume of the bypass passage 19c by changing the opening degrees thereof. The air mix door 26 adjusts the temperature of the conditioned air flowing out from the air conditioner unit 11 by adjusting the air volume ratio.

The door position at which the air mix door 26 minimizes the opening of the hot air passage 19b and maximizes the opening of the bypass passage 19c (eg, 100%) is referred to as the MAXCOOL position. In this embodiment, when the door position of the air mix door 26 is at its MAXCOOL position, the hot air passage 19b is closed. In FIG. 5, the air mix door 26 is shown in the MAXCOOL position.

The door position at which the air mix door 26 maximizes the opening of the hot air passage 19b (for example, 100%) and minimizes the opening of the bypass passage 19c is called the MAXHOT position. In this embodiment, the bypass passage 19c is blocked when the door position of the air mix door 26 is at its MAXHOT position.

The vehicle 80 also has a D-seat side airflow direction changing device 92 provided in the D-seat side air outlet 911 and a P-seat side airflow direction changing device 93 provided in the P-seat side air outlet 912 . The D-seat side wind direction changing device 92 changes the blowing direction of the air blowing out from the D-seat side face air outlet 911a. For example, the D-seat side wind direction changing device 92 has a louver and an actuator 921 provided on the D-seat side face air outlet 911a. Change the blowing direction of 911a.

Then, the P-seat side wind direction changing device 93 changes the blowing direction of the air blown out from the P-seat side face air outlet 912a. For example, the P-seat side wind direction changing device 93 has a louver and an actuator 931 provided at the P-seat side face air outlet 912a. Change the blowing direction of 912a.

The louver of the D-seat side airflow direction changing device 92 is configured such that the direction of the louver can be freely changed manually when the D-seat side airflow direction changing device 92 is not operated and the actuator 921 is not energized. This also applies to the louver of the P-seat side wind direction changing device 93 .

The air conditioner control device 12 shown in FIG. 3 is composed of a microcomputer including a CPU, ROM, RAM and the like (not shown). A signal from a sensor or the like connected to the air conditioner control device 12 is input to the air conditioner control device 12 after being A/D converted by an input circuit (not shown). For example, signal lines connecting the air conditioner control device 12 and a plurality of connected devices such as sensors electrically connected to the air conditioner control device 12 may be connected in parallel from the air conditioner control device 12 to each connected device. and may be connected in series. If the signal lines are serially connected, the LIN protocol or the like is used.

As shown in FIG. 3, a plurality of input side connection devices 121 to 126 are electrically connected to the air conditioner control device 12 . The plurality of input side connection devices 121 to 126 are, for example, a D seat side door opening/closing sensor 121, a P seat side door opening/closing sensor 122, an outside air temperature sensor 123, a cancel switch 124, an ignition switch 125, and a battery voltage sensor 126. . Signals from these input side connection devices 121 to 126 may be input to the air conditioner control device 12 via another control device other than the air conditioner control device 12, or may be input to the other control device. The data may be directly input to the air conditioner control device 12 without passing through.

The D-seat door opening/closing sensor 121 detects whether or not the D-seat door 86 has opened the D-seat door opening 82 . In short, the D-seat door open/close sensor 121 detects opening/closing of the D-seat door 86 . A detection signal indicating the open/closed state of the D-seat door 86 is input from the D-seat door opening/closing sensor 121 to the air conditioner control device 12 . Therefore, based on the detection signal from the D-seat door opening/closing sensor 121 , the air conditioner control device 12 recognizes that the D-seat door 86 has opened the D-seat door opening 82 .

The P-seat door opening/closing sensor 122 detects whether or not the P-seat door 88 opens the P-seat door opening 84 . In short, the P-seat door opening/closing sensor 122 detects opening/closing of the P-seat door 88 . A detection signal indicating the open/close state of the P-seat door 88 is input from the P-seat door opening/closing sensor 122 to the air conditioner control device 12 . Therefore, based on the detection signal from the P-seat door opening/closing sensor 122, the air conditioner control device 12 recognizes that the P-seat door 88 has opened the P-seat door opening 84. FIG.

Also, the outside air temperature sensor 123 detects an outside air temperature Tam, which is the temperature of the outside air around the vehicle 80 . A detection signal indicating the outside air temperature Tam is input from the outside air temperature sensor 123 to the air conditioner control device 12 .

The cancel switch 124 is an occupant-operated switch that is operated by the occupant, and is provided at a location such as the instrument panel 91 where the occupant can easily operate the cancel switch 124 . Specifically, the cancel switch 124 is a switch that switches between permission and non-permission for executing the control process of FIG. 6, which will be described later. That is, the cancel switch 124 is a switch that switches between permission and non-permission for blowing air from the predetermined air outlet Ps while the door 86, 88 is opening one of the door openings 82, 84. be. The side face outlets 911a and 912a correspond to the predetermined outlets Ps referred to here.

Also, the ignition switch 125 is a vehicle activation switch that is turned on and off by the occupant in order to make the vehicle 80 ready to run. Therefore, when the ignition switch 125 is turned off, the vehicle 80 cannot run. Conversely, when the ignition switch 125 is turned on, the vehicle 80 is ready to run. For example, the vehicle 80 starts by depressing the accelerator pedal after the ignition switch 125 is turned on. Although the vehicle 80 of this embodiment is an engine vehicle as described above, if the vehicle 80 is a hybrid vehicle or an electric vehicle, the ignition switch 125 is called a vehicle activation switch, for example.

A signal indicating ON/OFF of the ignition switch 125 is input from the ignition switch 125 to the air conditioner control device 12 . The ignition switch 125 may be, for example, a key inserted into a keyhole or a push button. Note that when the ignition switch 125 is turned off, the power of predetermined in-vehicle equipment such as audio equipment mounted in the vehicle 80 is also turned off.

Battery voltage sensor 126 detects voltage Vb of a battery that is the power supply of vehicle 80 (in other words, power supply voltage Vb). A detection signal indicating the battery voltage Vb is input from the battery voltage sensor 126 to the air conditioner control device 12 .

Further, the air conditioner control device 12 is electrically connected to the D seat side air direction changing device 92, the P seat side air direction changing device 93, the air conditioner unit 11, and the like as output side connection devices. For example, the air conditioner control device 12 outputs a control signal for controlling the operation of each of the D seat side wind direction changing device 92, the P seat side wind direction changing device 93, and the air conditioner unit 11 respectively. Specifically, the control signal for the air conditioner unit 11 is a control signal for controlling the operation of each component of the air conditioner unit 11 such as the blower 14 .

The air conditioner control device 12 executes a computer program stored in a semiconductor memory such as ROM, RAM, etc., which is a non-transitional material storage medium. By executing this computer program, a method corresponding to the computer program is executed. That is, the air conditioner control device 12 executes various control processes such as the control process shown in FIG. 6 according to the computer program.

FIG. 6 is a flowchart showing control processing executed by the air conditioner control device 12 of this embodiment. Since the cancel switch 124 is provided in this embodiment, the air conditioner control device 12 performs the control process of FIG. 6 only when the execution of the control process of FIG. to run. The control processing in FIG. 6 is periodically and repeatedly executed.

As shown in FIGS. 3 and 6, air conditioner control device 12 first acquires signals from outside air temperature sensor 123, ignition switch 125, and battery voltage sensor 126 in step S011. Thereby, the air conditioner control device 12 recognizes the outside air temperature Tam, the ON/OFF state of the ignition switch 125, and the battery voltage Vb. After step S011, the process proceeds to step S021.

In step S021, the air conditioner control device 12 determines whether or not the outside air temperature Tam is equal to or higher than a predetermined outside air temperature lower limit value T1am and not higher than a predetermined outside air temperature upper limit value T2am. The outside air temperature upper limit T2am is higher than the outside air temperature lower limit T1am.

The lower limit value T1am and the upper limit value T2am of the outside temperature are experimentally determined in advance so that the temperature range from the lower limit value T1am to the upper limit value T2am of the outside temperature matches the temperature range in which mosquitoes fly around. This is because the control process of FIG. 6 is executed to prevent foreign matter such as mosquitoes from entering the vehicle compartment.

When it is determined in step S021 that the outside air temperature Tam is equal to or higher than the outside air temperature lower limit value T1am and below the predetermined outside air temperature upper limit value T2am, the process proceeds to step S031. On the other hand, if it is determined that the outside air temperature Tam is less than the outside air temperature lower limit T1am, or if it is determined that the outside air temperature Tam is higher than the outside air temperature upper limit T2am, the process proceeds to step S171.

In step S031, the air conditioner control device 12 determines whether or not the battery voltage Vb is equal to or higher than a predetermined voltage determination value V1b. The voltage determination value V1b is experimentally determined in advance so that it can be determined that the battery is insufficiently charged when the battery voltage Vb is less than the voltage determination value V1b.

When it is determined in step S031 that the battery voltage Vb is equal to or higher than the voltage determination value V1b, the process proceeds to step S041. On the other hand, when it is determined that the battery voltage Vb is less than the voltage determination value V1b, the process proceeds to step S171.

In step S041, the air conditioner control device 12 determines whether or not the ignition switch 125 is turned off (that is, turned off).

When it is determined in step S041 that the ignition switch 125 is off, the process proceeds to step S051. On the other hand, if it is determined that the ignition switch 125 is not off, the process proceeds to step S171. It is assumed that the ignition switch 125 is turned on or switched to another switch state that is neither on nor off.

In step S<b>051 , the air conditioner control device 12 acquires a signal from the D seat side door open/close sensor 121 . Thereby, the air conditioner control device 12 recognizes the opened/closed state of the D-seat side door 86 shown in FIG.

Then, the air conditioner control device 12 determines whether or not the D-seat side door 86 is opening the D-seat side door opening 82 and the door is being opened.

If it is determined in step S051 that the D-seat side door opening 82 is being opened, the process proceeds to step S071. On the other hand, if it is determined that the D-seat side door opening 82 is not being opened, the process proceeds to step S061. The case where the D-seat side door opening 82 is not open is, specifically speaking, the case where the D-seat side door 86 blocks the D-seat side door opening 82 and the door is closed. .

As shown in FIGS. 3 and 6, in step S061, the air conditioner control device 12 acquires a signal from the P-seat side door open/close sensor 122. FIG. Thereby, the air conditioner control device 12 recognizes the opened/closed state of the P-seat side door 88 shown in FIG.

Then, the air conditioner control device 12 determines whether or not the P-seat side door 88 is opening the P-seat side door opening 84 and the door is being opened.

If it is determined in step S061 that the P-seat side door opening 84 is being opened, the process proceeds to step S131. On the other hand, if it is determined that the P-seat side door opening 84 is not being opened, the process proceeds to step S171. The case where the P-seat side door opening 84 is not open is, specifically speaking, the case where the P-seat side door 88 blocks the P-seat side door opening 84 and the door is closed. .

As shown in FIGS. 3 and 6, in step S071, the air conditioner control device 12 controls the air conditioner unit 11 to prevent foreign matter such as mosquitoes from entering the passenger compartment through the door openings 82 and 84 while the doors are open. to the predetermined intrusion prevention mode. If the air conditioner unit 11 is already in the intrusion prevention mode, the intrusion prevention mode is continued.

Specifically, in the intrusion prevention mode, the intake mode of the air conditioner unit 11 is set to the outside air mode. Also, the door position of the air mix door 26 is set to the MAXCOOL position. Also, the air blowing mode of the air conditioner unit 11 is set to face mode. The face mode is a mode in which air is blown out exclusively from the face blow-out openings 191a, 191b, 191c and 191d, and the opening and closing of the face doors 28, 30 and 32 follow steps S091, S111 and S141 to be described later. Therefore, in this step S071, the air conditioner control device 12 closes the defroster door 33 and the foot door 34 without operating the face doors 28, 30, and 32. After step S071, the process proceeds to step S081.

In step S081, the air conditioner control device 12 performs the same processing as in step S061 described above. That is, the air conditioner control device 12 recognizes the open/closed state of the P-seat side door 88 shown in FIG. Then, the air conditioner control device 12 determines whether or not the P-seat side door opening 84 is being opened.

If it is determined in step S081 that the P-seat side door opening 84 is being opened, the process proceeds to step S111. On the other hand, if it is determined that the P-seat side door opening 84 is not being opened, the process proceeds to step S091.

As shown in FIGS. 3 and 6, in step S091, the air conditioner control device 12 opens the face blowing openings 191a, 191b, 191c, and 191d on the seat D side. If the face blowing openings 191a, 191b, 191c, and 191d are already in the D seat side open state, the D seat side open state is continued.

Specifically, in the D-seat side open state, the D-seat side side face blowing opening 191 a is opened by the D-seat side side face door 28 . On the other hand, the P-seat side side face air outlet opening 191b is closed by the P-seat side side face door 30, and the center face air outlet openings 191c and 191d are closed by the center face door 32. Therefore, after the processing of step S091 is completed, all of the air outlet openings other than the side face air outlet opening 191a on the side of the D seat are closed. After step S091, the process proceeds to step S101.

Note that FIG. 4 shows the open state of the face air outlet openings 191a, 191b, 191c, and 191d on the seat D side. Specifically, in FIG. 4, the P-seat side side face blowout opening 191b and the center face blowout openings 191c, 191d are hatched with dots, indicating that the blowout openings 191b, 191c, 191d are closed. It is shown that. Further, the point hatching indicates that the blow-out opening is closed, which is the same in the later-described figures similar to FIG. 4 .

In step S101 of FIG. 6, the air conditioner control device 12 causes the D-seat side airflow direction changing device 92 to direct the airflow direction of the D-seat side face air outlet 911a toward the outside of the vehicle through the D-seat door opening 82. to the outward outlet mode. As a result, as shown in FIGS. 1 and 4, the D-seat side face air outlet 911a directs air from the interior side of the D-seat side door opening 82 to the exterior side of the vehicle through the D-seat side door opening 82. It becomes a blowout port that blows out. In other words, the D-seat side face air outlet 911a serves as an air outlet for blowing air from the interior side of the D-seat side door opening 82 to the exterior side of the vehicle so as to pass through the D-seat side door opening 82. . For example, as shown in FIG. 1, the blowing direction of the D seat side side face blowing outlet 911a in the outward blowing outlet mode is directed to the rear side of the vehicle and obliquely to the right side of the vehicle. stipulated in After step S101, the process proceeds to step S161.

Here, since the blower 14 is operated in step S161, which will be described later, when step S161 is executed following step S101, the side face blower on the side of the D seat will be exclusively blown as indicated by the arrow Ard in FIGS. Air is blown out from the outlet 911a. In this embodiment, the D-seat side side face outlet 911a and the P-seat side side face outlet 912a correspond to the predetermined outlet Ps. That is, two predetermined outlets Ps are provided in this embodiment.

Therefore, in step S101, the air conditioner control device 12 controls the D-seat side wind direction changing device 92 when blowing air from the predetermined outlet Ps while the D-seat side door opening 82 is open. It can be said that the blowing direction of the predetermined blower outlet Ps is directed toward the outside of the vehicle.

7 and 8 illustrate the signals that the air conditioner control device 12 exchanges when step S161 is executed following step S101. Also, "I/G" shown in FIG. 8 is an abbreviation for an ignition switch.

As shown in FIGS. 3 and 6, in step S111, the air conditioner control device 12 opens the face outlet openings 191a, 191b, 191c, and 191d on both sides. If the face outlet openings 191a, 191b, 191c, and 191d are already open on both sides, the open state on both sides is maintained.

Specifically, in the both-sides open state, the D-seat side face blow-out opening 191a is opened by the D-seat side side face door 28, and the P-seat side side face blow-out opening 191b is opened by the P-seat side side face door 30. is opened by On the other hand, the center face blowout openings 191c and 191d are closed by the center face door 32. As shown in FIG. Therefore, after the processing of step S111 is completed, all of the blow-out openings other than the side face blow-out openings 191a and 191b on the D-seat and P-seat sides are closed. After step S111, the process proceeds to step S121.

Note that FIG. 9 shows a state in which both sides of the face outlet openings 191a, 191b, 191c, and 191d are open. Specifically, dotted hatching attached to the center face blowout openings 191c and 191d in FIG. 9 indicates that the center face blowout openings 191c and 191d are closed.

In step S121 of FIG. 6, the air conditioner control device 12 sets the D-seat side wind direction changing device 92 to the outward air outlet mode in the same manner as in step S101 described above.

In addition to this, the air conditioner control device 12 also sets the P-seat side wind direction changing device 93 to a predetermined outward outlet mode. In the outward outlet mode of the P-seat side airflow direction changing device 93, the P-seat side airflow direction changing device 93 directs the airflow direction of the P-seat side face outlet 912a to the outside of the passenger compartment through the P-seat side door opening 84. turn to As a result, as shown in FIGS. 1 and 9, the P-seat side face air outlet 912a directs air from the interior side of the P-seat side door opening 84 to the exterior side of the vehicle through the P-seat side door opening 84. It becomes a blowout port that blows out. In other words, the P-seat side face air outlet 912a serves as an air outlet for blowing air from the interior side of the P-seat side door opening 84 to the exterior side of the passenger compartment so as to pass through the P-seat side door opening 84. . For example, the air blowing direction of the P-seat side face air outlet 912a in the outward air outlet mode is directed toward the rear side of the vehicle and obliquely to the left side of the vehicle, and the air blowing direction is experimentally determined in advance. After step S121, the process proceeds to step S161.

Here, the blower 14 is operated in step S161, which will be described later. Therefore, when step S161 is executed following step S121, air is blown out exclusively from the D-seat side and P-seat side side face outlets 911a and 912a as indicated by arrows Ard and Arp in FIG. . As described above, in this embodiment, the D-seat side side face outlet 911a and the P-seat side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following in step S121. That is, when the air conditioner control device 12 blows air from the predetermined air outlet Ps while the door openings 82, 84 on the D-seat side and the P-seat side are open, the air-conditioning control device 12 controls the D-seat-side and P-seat-side wind direction changing devices 92 , 93, the blowing direction of the predetermined outlet Ps is directed toward the outside of the passenger compartment.

As shown in FIGS. 3 and 6, in step S131, the air conditioner control device 12 performs the same processing as in step S071 described above. That is, the air conditioner control device 12 puts the air conditioner unit 11 into the intrusion prevention mode. If the air conditioner unit 11 is already in the intrusion prevention mode, the intrusion prevention mode is continued. After step S131, the process proceeds to step S141.

In step S141, the air conditioner control device 12 opens the face blowing openings 191a, 191b, 191c, and 191d to the P seat side. If the face air outlet openings 191a, 191b, 191c, and 191d are already in the P-seat side open state, the P-seat side open state is continued.

Specifically, in the P-seat side open state, the P-seat side side face air opening 191b is opened by the P-seat side side face door 30 . On the other hand, the D-seat side side face blow-out opening 191 a is closed by the D-seat side side face door 28 , and the center face blow-out openings 191 c and 191 d are closed by the center face door 32 . Therefore, after the processing of step S141 is completed, all of the blow-out openings other than the P-seat side face blow-out opening 191b are closed. After step S141, the process proceeds to step S151.

In step S151, the air conditioner control device 12 sets the P-seat side wind direction changing device 93 to the outward air outlet mode in the same manner as in step S121 described above. However, unlike step S121, the air conditioner control device 12 does not operate the D-seat side airflow direction changing device 92 . After step S151, the process proceeds to step S161.

Here, the blower 14 is operated in step S161, which will be described later. Therefore, when step S161 is executed following step S151, air is blown out exclusively from the P-seat side side face outlet 912a as indicated by the arrow Arp in FIG. As described above, in this embodiment, the D-seat side side face outlet 911a and the P-seat side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following in step S151. That is, when the air conditioner control device 12 blows air from the predetermined air outlet Ps while the P-seat side door opening 84 is open, the air conditioner control device 12 controls the P-seat side wind direction changing device 93 so that the air is blown from the predetermined air outlet Ps. It can be said that the blowing direction of Ps is directed to the outside of the passenger compartment.

In step S161, the air conditioner control device 12 activates the blower 14 and causes the blower 14 to blow air. For example, the air conditioner control device 12 operates the blower 14 to blow air at the maximum air volume. If the blower 14 is already in operation, it will continue.

In step S171, the air conditioner control device 12 stops the blower 14 that has been activated in step S161. If the blower 14 is already stopped, it continues as it is. It should be noted that the process of step S171 does not stop the blower 14 when the blower 14 is in operation by a control process other than the control process shown in FIG. After steps S161 and S171, the process returns to step S011.

The air conditioner control device 12 performs the control processing of FIG. 6 as described above. As a result, as shown in FIG. 1, the air conditioner control device 12 activates the blower 14 while the D seat side door opening 82 is open, and directs the air flowed by the blower 14 to the D seat side side face duct 39 . through the D-seat side side face outlet 911a.

In the control process of FIG. 6, the air conditioner control device 12 operates the blower 14 while the P-seat side door opening 84 is open, and directs the air flowed by the blower 14 through the P-seat side side face duct 40. Air is blown out from the P-seat side side face outlet 912a.

For example, a case where an occupant attempts to get on the vehicle through the D-seat door opening 82 will be described. In this example, the occupant opens the D-seat door 86 as shown in FIG. When the D-seat side door 86 is opened in this way, if the determinations in steps S021 to S041 in FIG. 6 are all "YES", the blower 14 draws outside air as indicated by the arrow Ari in FIG. The sucked air (specifically, outside air) passes from the blower 14 through the evaporator 22 and the bypass passage 19c in order, and then flows out from the D-seat side side face blow-out opening 191a in FIG.

The air flowing out from the D-seat side face blow-out opening 191a passes through the D-seat side side face duct 39 and is blown out from the D-seat side face blow-out port 911a as indicated by the arrow Ard in FIGS. . If, for example, a mosquito 99 tries to enter the passenger compartment, it is blown away outside the passenger compartment by the wind blowing from the D-seat side side face outlet 911a as indicated by the arrow Ard. After that, when the occupant gets on from the D-seat side door opening 82 and closes the D-seat side door 86, the blower 14 is stopped in step S171 of FIG. Also, when the passenger turns on the ignition switch 125, step S161 is not executed due to the determination in step S141 of FIG.

Note that the processing in each step in FIG. 6 described above constitutes a functional unit that implements each function, and the air conditioner control device 12 has that functional unit. This also applies to flowcharts described later.

As described above, according to this embodiment, the air conditioner control device 12 executes the control process shown in FIG. As a result, while the D-seat side door opening 82 in FIG. The air is blown out from the D-seat side side face outlet 911a as the outlet Ps. At this time, the D-seat side face air outlet 911a blows air from the inside of the passenger compartment to the outside of the passenger compartment through the D-seat door opening 82 while the door is open.

Further, while the P-seat side door opening 84 is being opened, the air conditioner control device 12 operates the blower 14, and directs the air blown by the blower 14 through the P-seat side face duct 40 to the predetermined outlet Ps. It is blown out from the P seat side side face outlet 912a as. At this time, the P-seat side face air outlet 912a blows air from the inside of the passenger compartment to the outside of the passenger compartment through the P-seat door opening 84 while the door is open.

Therefore, when a foreign matter such as a mosquito 99 attempts to enter the vehicle through the door openings 82, 84 while the doors are open, the foreign matter is blown away from the vehicle by the air flow from the predetermined outlet Ps. In this way, it is possible to prevent foreign matter from entering the vehicle interior through the door openings 82 and 84 while the doors are open.

Air-conditioning air flowing out from the air-conditioning unit 11 when the air-conditioning unit 11 air-conditions the vehicle interior also flows through both the side face ducts 39 and 40, which are air-conditioning ducts connected to the predetermined outlet Ps. Therefore, a side face duct 39 used for air-conditioning the vehicle interior does not require a dedicated duct for blowing air from the predetermined air outlet Ps for the purpose of suppressing foreign matter from entering the vehicle interior. , 40 can be used. Therefore, it is possible to improve the mountability of the air blowing device 10 on the vehicle 80 .

Further, according to the present embodiment, as shown in FIGS. 4 and 9, the D seat side side face outlet 911a serving as the predetermined outlet Ps is used when the air conditioner unit 11 air-conditions the vehicle interior. The conditioned air passing through the seat side side face duct 39 is blown out. Further, the P-seat side face air outlet 912a as a predetermined air outlet Ps blows out conditioned air that has passed through the P-seat side face duct 40 when the air conditioner unit 11 air-conditions the vehicle interior.

Therefore, the predetermined outlet Ps is not a dedicated outlet for blowing out air for the purpose of suppressing foreign matter from entering the passenger compartment. That is, the side face outlets 911a and 912a for air conditioning, which are used when air-conditioning the interior of the vehicle, can be used as the predetermined outlets Ps. Therefore, it is possible to improve the mountability of the air blowing device 10 on the vehicle 80 . In addition, since the number of parts can be reduced as compared with the case where a dedicated outlet is provided as the predetermined outlet Ps, the cost of the air blower 10 can be reduced.

Further, according to the present embodiment, as shown in FIGS. 6 and 8, when the air conditioner control device 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open, , do the following: That is, when air is blown out in this manner, the air conditioner control device 12 controls one or both of the D-seat side and P-seat side airflow direction changing devices 92 and 93 to change the blowing direction of the predetermined blower outlet Ps. toward the outside of the vehicle.

Therefore, when suppressing foreign matter such as mosquitoes from entering the vehicle interior through the door openings 82 and 84 while the doors are open, the air-conditioning side face outlets 911a and 912a used as the predetermined outlets Ps blow out in the direction of blowing. can be properly oriented.

Further, according to the present embodiment, as shown in FIGS. 5 and 6, when the air conditioner control device 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open, Then, the air mix door 26 is caused to open the bypass passage 19c. Specifically, the air conditioner control device 12 sets the door position of the air mix door 26 to the MAXCOOL position.

Therefore, when the air is blown out from the predetermined outlet Ps while the door is open, it is possible to prevent the heater core 24 from increasing the ventilation resistance in the air conditioner unit 11 . As a result, it is possible to increase the amount of air blown out from the predetermined outlet Ps while the door is open.

Further, according to the present embodiment, as shown in FIGS. 1 and 6, when the air conditioner control device 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open, Then, the air conditioner unit 11 is set to the outside air mode. Therefore, it is possible to prevent the air blown from the predetermined outlet Ps from being drawn into the passenger compartment by the blower 14 . As a result, compared to the case where the air conditioner unit 11 is in the internal air mode, for example, it is possible to improve the performance of preventing foreign matter from entering the vehicle interior through the door openings 82 and 84 while the doors are open.
Furthermore, when a passenger gets on the vehicle through the open door openings 82 and 84, the outside air is blown out from the predetermined outlets Ps to forcibly ventilate the air in the passenger compartment. For example, if a passenger gets in the car after being parked in the hot sun for a long time, it will be possible to quickly ventilate the hot air in the passenger compartment, and the cooling effect will be immediate after boarding and the air conditioning load will be reduced. has the effect of

Further, according to this embodiment, the center face outlets 913a and 914a are outlets different from the predetermined outlet Ps. When the air conditioner control device 12 blows air from the predetermined air outlet Ps while one or both of the door openings 82 and 84 are open, the air is blown into the passenger compartment from the center face air outlets 913a and 914a. stop blowing. Therefore, by stopping the flow of air to the center face outlets 913a and 914a, which are separated from the door openings 82 and 84 to some extent, it is possible to secure a large amount of air blown from the predetermined outlet Ps. It is possible.

Further, according to the present embodiment, the flowchart of FIG. 6 includes step S021 for making a determination regarding the outside air temperature Tam. That is, the air conditioner control device 12 opens one or both of the door openings 82 and 84 on the condition that the outside air temperature Tam is equal to or higher than a predetermined outside air temperature lower limit value T1am and below a predetermined outside air temperature upper limit value T2am. Air is blown out from a predetermined outlet Ps inside.

Therefore, under conditions where insect pests such as mosquitoes 99, which are typical examples of foreign matter that can enter the vehicle interior through the door openings 82 and 84, are stagnant, air should be blown out from the predetermined outlet Ps while the doors are open. will not be implemented. Therefore, when it becomes necessary to suppress foreign matter from entering the vehicle interior through the door openings 82 and 84 while the doors are open, it is recommended to blow air from the predetermined outlet Ps while the doors are open. It can be implemented as appropriate.

Further, according to the present embodiment, as shown in FIGS. 3 and 8, the air conditioner control device 12 opens the D seat side door 86 based on the detection signal from the D seat side door open/close sensor 121. It recognizes that the opening 82 has been opened. Based on the detection signal from the P-seat door opening/closing sensor 122 , the air conditioner control device 12 recognizes that the P-seat door 88 has opened the P-seat door opening 84 . Therefore, the air conditioner controller 12 can easily obtain information as to whether or not the D-seat side and P-seat side doors 86, 88 have opened the door openings 82, 84, respectively.

Further, according to the present embodiment, as shown in FIG. 3, the vehicle 80 is provided with a cancel switch 124 as an occupant operation switch. Only when the execution of the control process of FIG. 6 is permitted by the passenger's operation on the cancel switch 124, the air conditioner control device 12 executes the control process of FIG. More specifically, only when the passenger operates the cancel switch 124 to allow air to blow out from the predetermined air outlet Ps while the doors are open, the air conditioner control device 12 operates the predetermined air outlet while the doors are open. Air is blown out from the outlet Ps. Therefore, it is possible to stop blowing air from the predetermined outlet Ps while the door is open, according to the will of the occupant.

Further, according to the present embodiment, the flowchart of FIG. 6 includes step S031 for determining the battery voltage Vb. That is, on condition that the battery voltage Vb is equal to or higher than the predetermined voltage determination value V1b, the air conditioner control device 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. .

Therefore, when the battery mounted on the vehicle 80 is weak, it is possible to stop blowing air from the predetermined air outlet Ps while the door is open. In this embodiment, blowing air from the predetermined outlet Ps while the door is open is performed when the ignition switch 125 is off, so it is particularly effective to determine the battery voltage Vb in step S031. .

That is, also in this embodiment, two predetermined outlets Ps are provided as in the first embodiment.

Further, in this embodiment, the vehicle 80 does not have the D-seat side and P-seat side wind direction changing devices 92 and 93 of the first embodiment. Instead, the vehicle 80 has a D-seat side outlet switching device 94 and a P-seat side outlet switching device 95 . Each of these outlet switching devices 94 and 95 is electrically connected to the air conditioner control device 12 as an output side connection device. The operation of these outlet switching devices 94 and 95 is controlled by the air conditioner control device 12 .

Since the D-seat side outward air outlet 915 constitutes a part of the D-seat side wall 91a, the D-seat side outward air outlet 915a is formed in the D-seat side wall 91a. Accordingly, the D-seat side outward air outlet 915a is formed in the instrument panel 91 at a position closer to the right end than the D-seat side face air outlet 911a in the vehicle left-right direction DR2.

Further, since the P-seat side outward blowout portion 916 constitutes a part of the P-seat side wall 91b, the P-seat side outward blowout port 916a is formed in the P-seat side wall 91b. Therefore, the P-seat side outward air outlet 916a is formed in the instrument panel 91 at a position closer to the left end than the P-seat side face air outlet 912a in the vehicle left-right direction DR2. Note that both the D-seat side and P-seat side outward outlets 915a and 916a are provided in a part of the instrument panel 91, and are therefore provided in the vehicle interior.

As shown in FIG. 10, the D-seat side outward air outlet 915a is connected in parallel with the D-seat side face air outlet 911a, which is an air-conditioning outlet, on the downstream side of the air flow of the D-seat side face duct 39. there is Specifically, the D-seat side outward outlet 915a and the D-seat side face outlet 911a are connected to the outlet end 392 of the D-seat side face duct 39 via the D-seat side outlet switching device 94, respectively. ing.

That is, the D-seat side outlet switching device 94 selectively switches between the first communication state and the second communication state. Then, the D-seat side outlet switching device 94 in the first communication state connects the outlet end 392 of the D-seat side face duct 39 and the D-seat side face outlet 911a to communicate with each other. and the D-seat side outward outlet 915a. Conversely, the D-seat side outlet switching device 94 in the second communication state connects the outlet end 392 of the D-seat side face duct 39 and the D-seat side outward outlet 915a, while The communication between 392 and the D seat side side face outlet 911a is cut off.

The P-seat side outward air outlet 916a is connected to the P-seat side face duct 40 on the downstream side of the air flow in parallel with the P-seat side face air outlet 912a, which is an air conditioning outlet. Specifically, the P-seat side outward outlet 916a and the P-seat side face outlet 912a are connected to the outlet end 402 of the P-seat side face duct 40 via the P-seat side outlet switching device 95, respectively. ing.

The P-seat side air outlet switching device 95 changes the ventilation path so that the air passing through the P-seat side face duct 40 flows to either the P-seat side outward air outlet 916a or the P-seat side face air outlet 912a. switch. That is, the P-seat side outlet switching device 95 selectively switches between the first communication state and the second communication state. The P-seat side outlet switching device 95 in the first communication state connects the outlet end 402 of the P-seat side face duct 40 and the P-seat side face outlet 912a, while the outlet end 402 of the P-seat side face outlet 912a is and the P-seat side outward outlet 916a. Conversely, the P-seat side outlet switching device 95 in the second communication state connects the outlet end 402 of the P-seat side face duct 40 and the P-seat side outward outlet 916a, while The communication between 402 and the P-seat side side face outlet 912a is cut off.

When the air conditioner unit 11 air-conditions the vehicle interior, the air conditioner control device 12 sets the D-seat side and P-seat side outlet switching devices 94 and 95 to the first communication state, respectively. For example, the D-seat side and P-seat side outlet switching devices 94 and 95 may be brought into the second communication state by the control processing in FIG. 13, which will be described later. When the outlet switching devices 94 and 95 are in the second communication state in this manner, the air conditioner control device 12 controls the outlet switching device 94, 95 are switched from the second communication state to the first communication state.

The D-seat side outward air outlet 915a and the P-seat side outward air outlet 916a are dedicated air outlets for blowing out air according to the control processing shown in FIG. 13, which will be described later. is not used. That is, the D-seat side outward outlet 915a and the P-seat side outward outlet 916a are outlets different from the air conditioning outlets such as the face outlets 911a to 914a. Therefore, the blowing direction of the air blown from the D-seat side outward air outlet 915a and the air blowing direction of the air blown from the P-seat side outward air outlet 916a are fixed.

Specifically, the D-seat side outward air outlet 915a is directed toward the D-seat side door opening 82 from the inside of the passenger compartment to the outside of the passenger compartment. It is configured in advance so that air is blown out through the seat-side door opening 82 .

Air is blown out from the outlet 915a. That is, in this case, the air is blown out from the D-seat side outward outlet 915a as the predetermined outlet Ps.

In the flowchart of FIG. 13, step S111 is followed by step S122. In step S122, the air conditioner control device 12 brings the D-seat side and P-seat side outlet switching devices 94 and 95 into the second communication state, respectively. As a result, the air conditioner control device 12 can flow the air that has passed through the D seat side side face duct 39 to the D seat side outward outlet 915a. Then, the air conditioner control device 12 can flow the air that has passed through the P-seat side side face duct 40 to the P-seat side outward air outlet 916a.

If the D-seat side outlet switching device 94 is already in the second communication state, it continues as it is. Also, if the P-seat side outlet switching device 95 is already in the second communication state, it continues as it is. After step S122, the process proceeds to step S161.

Here, in step S161 of FIG. 13, the blower 14 is operated. Therefore, when step S161 is executed following step S122, air is blown out exclusively from the D-seat side and P-seat side outward outlets 915a and 916a as indicated by arrows Ard and Arp in FIG. That is, in this case, air is blown out from the D-seat side and P-seat side outward outlets 915a and 916a as the predetermined outlets Ps.

In the flowchart of FIG. 13, step S141 is followed by step S152. At step S152, the air conditioner control device 12 puts the P-seat side outlet switching device 95 into the second communication state. As a result, the air conditioner control device 12 can flow the air that has passed through the P-seat side face duct 40 to the P-seat side outward air outlet 916a. If the P-seat side outlet switching device 95 is already in the second communication state, it continues as it is. After step S152, the process proceeds to step S161.

Here, since the blower 14 is operated in step S161 of FIG. 13, when step S161 is executed following step S152, the P-seat side outward outlet 916a is exclusively operated as indicated by the arrow Arp in FIG. air is blown out from That is, in this case, the air is blown out from the P-seat side outward outlet 916a as the predetermined outlet Ps.

That is, when air is blown out in this way, the air conditioner control device 12 controls the D seat side outlet switching device 94 so that the air passing through the D seat side side face duct 39 is directed outward to the D seat side. It flows to the outlet 915a.

Similarly for the P seat side, the air conditioner control device 12 performs the following when blowing air from the P seat side outward outlet 916a while the door of the P seat side door opening 84 is open. . That is, when air is blown out in this way, the air conditioner control device 12 controls the P-seat side outlet switching device 95 so that the air passing through the P-seat side side face duct 40 is directed outward to the P-seat side. It flows to the outlet 916a.

As described above, according to this embodiment, the D-seat side outward outlet 915a is provided as a separate outlet from the air conditioning outlets 911a to 914a. The blowing direction of the D seat side outward blowing port 915a is fixed. Specifically, the D-seat side outward air outlet 915a is directed toward the D-seat side door opening 82 from the inside of the passenger compartment to the outside of the passenger compartment. It is configured in advance so that air is blown out through the seat-side door opening 82 . Therefore, it is possible to simply form the D-seat side outward air outlet 915a without the need to provide the D-seat side outward air outlet 915a with a function of changing the air outlet direction. As a result, for example, there is an advantage that it is easy to improve the performance of preventing foreign matter from entering the passenger compartment through the D-seat side door opening 82 while the door is open. This also applies to the P-seat side outward outlet 916a.

Further, according to the present embodiment, the air conditioner control device 12 executes control processing shown in FIG. 13 . Thus, the air conditioner control device 12 performs the following when blowing air from the D-seat side outward outlet 915a while the D-seat side door opening 82 is open. That is, when air is blown out in this way, the air conditioner control device 12 controls the D seat side outlet switching device 94 so that the air passing through the D seat side side face duct 39 is directed outward to the D seat side. It flows to the outlet 915a. The D-seat side outward air outlet 915a is connected to the air flow downstream side of the D-seat side face duct 39 in parallel with the D-seat side side face air outlet 911a, which is an air conditioning outlet.

Therefore, it is possible to provide the D-seat side outward air outlet 915a as a dedicated air outlet for the purpose of preventing foreign matter from entering the passenger compartment through the D-seat side door opening 82 while the door is open. Therefore, the D-seat side outward outlet 915a can have a nozzle shape suitable for preventing foreign matter such as mosquitoes 99 from entering the passenger compartment through the D-seat side door opening 82 while the door is open. is. As a result, for example, it is possible to improve the performance of preventing foreign matter from entering the passenger compartment through the D-seat side door opening 82 while the door is open. This also applies to the P-seat side outward outlet 916a.

Further, it is possible to automatically switch the outflow destination of the air from the D seat side side face duct 39 to the D seat side outward air outlet 915a and the D seat side side face air outlet 911a. The same applies to the outflow destination of the air from the P seat side side face duct 40 .

Further, according to the present embodiment, the D-seat side outward air outlet 915a is formed in the instrument panel 91 at a position closer to the right end than the D-seat side side face air outlet 911a in the vehicle left-right direction DR2. there is The P-seat side outward air outlet 916a is formed in the instrument panel 91 at a position closer to the left end than the P-seat side face air outlet 912a in the vehicle left-right direction DR2.

Therefore, the D-seat side and P-seat side outward air outlets 915a and 916a are less conspicuous from the perspective of passengers in the passenger compartment, so that the influence on the design of the passenger compartment can be reduced. In addition, it is easy to improve the vehicle mountability of the parts forming the outward outlets 915a and 916a.

Further, according to the present embodiment, the D seat side wall 91a of the instrument panel 91 is covered with the D seat side door 86 with the D seat side door opening 82 closed, and the D seat side outward outlet 915a is covered with the D seat side door 86. is formed on the D seat side wall 91a. The P-seat side wall 91b of the instrument panel 91 is covered by the P-seat side door 88 with the P-seat side door opening 84 closed, and the P-seat side outward outlet 916a is located on the P-seat side wall 91b. is formed in Therefore, the outward outlets 915a and 916a are hidden from the passengers in the vehicle interior by the doors 86 and 88 with the door openings 82 and 84 closed, so that the influence on the design of the vehicle interior can be reduced. .

Except for what has been described above, this embodiment is the same as the first embodiment. In addition, in the present embodiment, it is possible to obtain the same effects as in the first embodiment, which are provided by the configuration common to that of the first embodiment.

On the other hand, if it is determined that the portable device 891 has approached the vehicle 80 and has not entered the predetermined area Ax around the vehicle, the process proceeds to step S171.

As shown in FIGS. 16A and 16B, from step S071, the process proceeds to steps S111, S121 and S161 in order, and after step S161 proceeds to step S173. In step S193, which will be described later, determination regarding the elapsed time from the start of operation of the blower 14 is performed, so in step S161 of the present embodiment, measurement of the elapsed time is executed with the start of operation of the blower 14 set to zero. .

Further, as shown in FIGS. 16A and 16B, in the present embodiment, before it is determined in steps S173 and S183 to be described later whether the door openings 82 and 84 are being opened, the blower is turned on in step S161. 14 are activated. Therefore, even if the door openings 82 and 84 are closed, air is blown out from the D seat side and P seat side face outlets 911a and 912a.

In step S173, the air conditioner control device 12 performs the same processing as in step S051 of FIG. That is, the air conditioner control device 12 recognizes the open/closed state of the D-seat door 86 shown in FIG. Then, the air conditioner control device 12 determines whether or not the D-seat side door opening 82 is being opened.

If it is determined in step S173 that the D-seat side door opening 82 is being opened, the process proceeds to step S203. On the other hand, if it is determined that the D-seat side door opening 82 is not being opened, the process proceeds to step S183.

In step S183, the air conditioner control device 12 performs the same processing as in step S061 of FIG. That is, the air conditioner control device 12 recognizes the open/closed state of the P-seat side door 88 shown in FIG. Then, the air conditioner control device 12 determines whether or not the P-seat side door opening 84 is being opened.

Therefore, it is possible to avoid unnecessarily continuing the operation of the blower 14 .

Except for what has been described above, this embodiment is the same as the first embodiment. In addition, in the present embodiment, it is possible to obtain the same effects as in the first embodiment, which are provided by the configuration common to that of the first embodiment.

Although this embodiment is a modification based on the first embodiment, it is also possible to combine this embodiment with the above-described second embodiment.

(Fourth embodiment)
Next, a fourth embodiment will be described. In this embodiment, differences from the above-described first embodiment will be mainly described.

In this embodiment, the air conditioner control device 12 also executes the control process of FIG. 17 in parallel with the control process of FIG. This embodiment differs from the first embodiment in this respect.

FIG. 17 is a flowchart showing control processing executed by the air conditioner control device 12 of this embodiment. The control processing in FIG. 17 is executed in parallel with the control processing in FIG. 6, and the control processing in FIG. 6 and the control processing in FIG. 17 are periodically and repeatedly executed.

Further, in the same manner as in the first embodiment, in the present embodiment, the air conditioner control device 12 performs the control shown in FIG. 6 only when execution of the control process shown in FIG. Execute the process. Since the control process of FIG. 17 is executed on the assumption that the control process of FIG. No control processing is executed.

The air conditioner control device 12 first determines whether or not the engine of the vehicle 80 has been stopped by switching the ignition switch 125 in step S014 of FIG. In short, the air conditioner control device 12 determines whether or not the ignition switch 125 is switched to switch the engine of the vehicle 80 from an ON state in which the engine is operating to an OFF state in which the engine is stopped. In other words, the air conditioner control device 12 determines whether or not the vehicle 80 has been switched from a state in which it can travel to a state in which it cannot travel due to the passenger's operation on the ignition switch 125, which is a vehicle activation switch. For example, when the ignition switch 125 is switched from ON to OFF while the engine of the vehicle 80 is running, the engine switches from the ON state to the OFF state.

It should be noted that the engine off state determined in step S014 does not include temporary engine stop due to idling stop or the like. This is because such a temporary engine stop is not engine stop caused by switching the ignition switch 125 .

Further, when the engine of the vehicle 80 has already been turned off, it is not determined that the engine of the vehicle 80 has been switched from the on state to the off state by switching the ignition switch 125 .

If it is determined in step S014 that the engine of vehicle 80 has been switched from the ON state to the OFF state by switching ignition switch 125, the process proceeds to step S024.

On the other hand, if it is determined in step S014 that the engine of vehicle 80 has not been switched from the ON state to the OFF state by switching ignition switch 125, the process returns to the beginning of this flow chart. That is, the air conditioner control device 12 performs the determination of step S014 again.

In step S024, the air conditioner control device 12 puts the air conditioner unit 11 into a predetermined standby mode. Setting the air conditioner unit 11 to the standby mode means setting the air conditioner unit 11 to the intrusion prevention mode described above, closing the center face blowout openings 191c and 191d (see FIG. 4), and closing the side face blowout openings 191a and 191d (see FIG. 4). 191b is open.

That is, in this case, the air conditioner control device 12 switches the intake mode of the air conditioner unit 11 to the outside air mode by controlling the inside/outside air switching door 16 . Also, the air conditioner control device 12 operates the air mix door 26 to set the door position of the air mix door 26 to the MAXCOOL position. Further, the air conditioner control device 12 operates the center face door 32 to close the center face blowing openings 191c and 191d. Further, the air conditioner control device 12 operates the defroster door 33 to close the defroster blowout opening. Further, the air conditioner control device 12 operates the foot door 34 to close the foot blow-out opening. In addition, the air conditioner control device 12 operates the side face doors 28, 30 to open the D-seat side and P-seat side side face blowout openings 191a, 191b.

After the completion of the process of step S024, all blow-out openings other than the D-seat side and P-seat side side face blow-out openings 191a and 191b are closed.

Here, the inside/outside air switching door 16, the air mix door 26, the center face door 32, the defroster door 33, and the foot door 34 each change the air conditioner ventilation path, which is the ventilation path of the air flowing through the air conditioner unit 11, in terms of their functions. It is a route change device that That is, the air conditioner unit 11 has a plurality of route changing devices.

For example, the air conditioner ventilation path changed by the inside/outside air switching door 16 as a path changing device is the air flow upstream side of the blower 14 in the air conditioner unit 11 . Also, the air conditioner ventilation path changed by the air mix door 26 as a path changing device is the ventilation path from the upstream side to the downstream side of the air flow across the air mix door 26 shown in FIG. Further, the air conditioner ventilation path changed by the center face door 32 as a path changing device is the ventilation path toward the center face blowing openings 191 c and 191 d within the air conditioner unit 11 . Further, the air conditioner ventilation path changed by the defroster door 33 as a path changing device is the air ventilation path toward the defroster outlet opening in the air conditioner unit 11 . Further, the air conditioner ventilation path changed by the foot door 34 as the path changing device is the air ventilation path toward the foot outlet opening within the air conditioner unit 11 .

Any state of the air conditioner ventilation path established by each path change device in the above-described standby mode is determined by the air conditioner control device 12 from the predetermined air outlet Ps while the door openings 82 and 84 are open in the control processing of FIG. This state is established when air is blown out. For example, the state of the air conditioner ventilation path established by the air mix door 26 when the air conditioner unit 11 is in the standby mode is the state established by the air conditioner controller 12 in steps S071 and S131 of FIG. It should be noted that, in this embodiment, as in the first embodiment, the D-seat side side face outlet 911a and the P-seat side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following by the control processing of FIG. That is, when the engine of the vehicle 80 stops, the air conditioner control device 12 operates each route changing device so as to establish the target state of the air conditioner ventilation route in advance regardless of whether the doors 86 and 88 are opened or closed. . The target state of the air conditioner ventilation path is the state of the air conditioner ventilation path established when the air conditioner controller 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. is.

Except for what has been described above, this embodiment is the same as the first embodiment. In addition, in the present embodiment, it is possible to obtain the same effects as in the first embodiment, which are provided by the configuration common to that of the first embodiment.

Further, according to the present embodiment, when the engine of the vehicle 80 is stopped, the air conditioner control device 12 controls each route so that the target state of the air conditioner ventilation route is established in advance regardless of whether the doors 86 and 88 are opened or closed. Activate the change device. That is, when the vehicle 80 is switched from the state in which the vehicle 80 can travel to the state in which the vehicle 80 cannot travel due to the driver's operation on the ignition switch 125, the air conditioner control device 12 sets the target state in advance regardless of whether the doors 86 and 88 are opened or closed. Activate each rerouting device so that it is established. The target state of the air conditioner ventilation path is the state of the air conditioner ventilation path established when the air conditioner controller 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. is.

Therefore, as soon as one of the door openings 82, 84 is opened by the doors 86, 88, the door openings 82, 84 move from the interior side of the opened door openings 82, 84 to the exterior side of the vehicle. Air can be blown through the

Although this embodiment is a modification based on the first embodiment, it is also possible to combine this embodiment with the above-described second or third embodiment.

That is, the inlet ends 411, 421 of the two center face ducts 41, 42 are connected to the two center face blowing openings 191c, 191d via the center face opening/closing device 13, respectively.

The center face opening/closing device 13 opens and closes the ventilation passages between the inlet ends 411, 421 of the center face ducts 41, 42 and the center face blowing openings 191c, 191d. That is, the center face opening/closing device 13 opens and closes the two center face blowing openings 191 c and 191 d outside the air conditioner unit 11 .

For example, in the control process of FIG. 13, the center face blowout openings 191c and 191d are closed by the center face opening/closing device 13 in steps S091, S111 and S141.

Except for what has been described above, this embodiment is the same as the second embodiment. In addition, in the present embodiment, the same effects as in the second embodiment can be obtained from the configuration common to that of the second embodiment.

Further, according to this embodiment, the center face opening/closing device 13 is attached to the air conditioner unit 11, and opens and closes the center face blowing openings 191c and 191d. Therefore, even if the air conditioner unit 11 is not provided with the center face door 32, the amount of air blown out from the predetermined outlet Ps when the door openings 82 and 84 on the D seat side are open is can be obtained to the same extent. It should be noted that, in this embodiment, similarly to the second embodiment, the D-seat side outward outlet 915a and the P-seat side outward outlet 916a correspond to the above-described predetermined outlet Ps.

(Other embodiments)

Therefore, the predetermined outlet is not a dedicated outlet for blowing out air for the purpose of preventing foreign matter from entering the passenger compartment. That is, it is possible to use the air-conditioning outlet used for air-conditioning the vehicle interior as the predetermined outlet. Therefore, it is possible to improve the mountability of the air blowing device on the vehicle.

Further, according to the third aspect, there is provided an airflow direction changing device for changing the blowing direction of the air blown out from the predetermined blowout port. Then, when air is blown out from the predetermined outlet while the door is open, the control device controls the airflow direction changing device so that the direction of air blowing from the predetermined outlet is directed toward the outside of the passenger compartment. Therefore, when suppressing foreign matter such as mosquitoes from entering the passenger compartment through the door opening while the door is open, it is possible to appropriately direct the air-conditioning outlet used as the predetermined outlet. is.

According to the fourth aspect, the direction of air blowing from the predetermined air outlet is such that the air blows from the interior side of the door opening to the exterior side of the vehicle interior through the door opening. It is preconfigured to be Therefore, it is possible to simply form the predetermined outlet without the need to provide the predetermined outlet with a function of changing the direction of blowing. As a result, for example, there is an advantage that it is easy to improve the performance of preventing foreign matter from entering the vehicle interior through the door opening while the door is open.

According to the fifth aspect, the predetermined outlet is connected downstream of the air-conditioning duct in parallel with the air-conditioning outlet through which conditioned air is blown out when the air-conditioning unit air-conditions the vehicle interior. An outlet switching device is provided for switching the ventilation path so that the air passing through the air-conditioning duct flows either to the predetermined outlet or to the air-conditioning outlet. When air is blown out from the predetermined outlet while the door is open, the control device controls the outlet switching device so that the air that has passed through the air-conditioning duct flows to the predetermined outlet.

Therefore, it is possible to provide a predetermined air outlet as a dedicated air outlet for the purpose of preventing foreign matter from entering the vehicle interior through the door opening while the door is open. Therefore, it is possible to form the predetermined outlet into a nozzle shape suitable for preventing foreign matter such as mosquitoes from entering the passenger compartment through the door opening while the door is open. As a result, for example, it is possible to improve the performance of preventing foreign matter from entering the vehicle interior through the door opening while the door is open.

A second air passage is formed for flowing air around the heat exchanger. Further, the air conditioner unit has a passage opening/closing device for opening and closing the second air passage. The control device causes the passage opening/closing device to open the second air passage when blowing air from the predetermined outlet while the door is open. Therefore, it is possible to avoid an increase in ventilation resistance due to the heat exchanger in the air conditioner unit when air is blown out from the predetermined outlet while the door is open. As a result, it is possible to increase the amount of air blown out from the predetermined outlet while the door is open.

Further, according to the ninth aspect, the air conditioner unit is configured to be switchable between a plurality of intake modes including an outside air mode in which air outside the vehicle is introduced to the blower. Then, the control device sets the air conditioner unit to the outside air mode when blowing air from the predetermined outlet while the door is open. Therefore, it is possible to prevent the air blown from the predetermined outlet from being drawn into the passenger compartment by the blower. As a result, it is possible to improve the performance of preventing foreign matter from entering the vehicle interior through the door opening while the door is open, compared to the case where the blower sucks in the inside air.

Further, according to the tenth aspect, the air conditioner unit is positioned in the center of the vehicle in the left-right direction of the vehicle so that the air from the air conditioner unit can also flow to the center face outlet opening into the vehicle interior. provided in The center face outlet is a separate outlet from the predetermined outlet. Then, the control device stops blowing air from the center face air outlet into the vehicle interior when blowing air from the predetermined air outlet while the door is open. Therefore, it is possible to secure a large amount of air blown from a predetermined air outlet in response to stopping the air flow to the center face air outlet located at a certain distance from the door opening.

Further, according to the eleventh aspect, the control device blows air from the predetermined air outlet while the door is open on condition that the outside air temperature is equal to or higher than a predetermined lower limit value of outside air temperature and lower than or equal to a predetermined upper limit value of outside air temperature. let it blow out. Therefore, in a situation where the activity of pests such as mosquitoes, which are typical examples of foreign matter that can enter the passenger compartment through the door opening, is stagnant, the air is not blown out from the predetermined outlet while the door is open. Become. Therefore, when it becomes necessary to prevent foreign matter from entering the vehicle interior through the door opening while the door is open, it is necessary to appropriately blow air from a predetermined air outlet while the door is open. is possible.

Further, according to the twelfth aspect, the air conditioner unit has a route changing device for changing an air conditioner ventilation route, which is a ventilation route for air flowing through the air conditioner unit. When the vehicle is switched from a drivable state to a drivable state by an occupant's operation of the vehicle start switch, the control device establishes an air conditioner when blowing air from a predetermined outlet while the door is open. A route changing device is operated so as to establish a target state of the ventilation route in advance regardless of whether the door is opened or closed. Therefore, as soon as the door opening is opened by the door, the air can be blown out from the interior side of the door opening to the outside of the vehicle interior through the door opening.

Further, according to the thirteenth aspect, the control device recognizes that the door has opened based on a signal from a door opening/closing sensor that detects opening/closing of the door. Therefore, the control device can easily obtain information as to whether or not the door has opened the door opening.

According to the fourteenth aspect, the vehicle is provided with an occupant operation switch for switching between permission and non-permission for blowing air from a predetermined air outlet while the door is open. Only when the occupant operates the occupant operation switch to allow the air to blow from the predetermined air outlet while the door is open, the control device blows air from the predetermined air outlet while the door is open. Therefore, it is possible to stop blowing air from the predetermined outlet while the door is open, according to the will of the occupant.

Moreover, according to the fifteenth aspect, the control device performs the following. That is, when a portable device that performs wireless communication with an in-vehicle radio device installed in a vehicle approaches the vehicle and enters a predetermined area around the vehicle, the control device will be activated even if the door opening is not opened by the door. , the blower is operated, and the air blown by the blower is blown out from a predetermined outlet. Therefore, it is possible to blow air from the inside of the vehicle interior to the outside of the vehicle through the door opening without delay from the moment the door opening is opened by the door.

Further, according to the sixteenth aspect, when the portable device is approaching the vehicle and has entered the predetermined area, the control device operates the blower while the door opening is closed by the door. When a predetermined time has passed since then, the blower is stopped. Therefore, it is possible to avoid unnecessarily continuing the operation of the blower.
