Japanese Examined Patent Publication No. 63-40006

  However, when the system as described above is used for a vehicle, there are concerns about the following inconveniences because there are circumstances different from those of home appliances. That is, in the vehicle, the space for supplying ion particles is narrower than the space planned for home appliances, so if there is a passenger, most of the generated ion particles adhere to the passenger, and the sterilization effect There is a disadvantage that the deodorizing effect and the refreshing effect cannot be sufficiently expected. In addition, due to the principle of the plasma cluster system, ozone is generated when the wind stops flowing to the ion generator. Therefore, there is a concern that ozone odor may be filled in a narrow space such as a passenger compartment.

In view of this, the main object of the present invention is to provide a vehicle air cleaning device capable of improving the functions and effects of the plasma cluster in order to eliminate the inconveniences described above and clean the passenger compartment.

In such a configuration, an operation state determination unit that determines the operation state of the vehicle is provided, and when the operation state of the vehicle is determined by the operation state determination unit, the sub air blower is stopped and switched. You may add the structure which interrupts | blocks a sub ventilation path | route while ensuring a main ventilation path | route by a damper (Claim 2).

Therefore, when the vehicle is stopped, the air blowing unit is activated and the ion generator is activated, so that the ion particles can be released to the passenger compartment even when the passenger is absent, and the ion particles adhere to the passenger. It can be efficiently diffused into the passenger compartment without causing it.
Further , according to such a configuration, when the operation of the vehicle is stopped, the auxiliary air blowing device operates separately from the main air blowing device, and the ion particles are supplied to the vehicle compartment via the auxiliary air blowing path , so that the conditioned air is supplied. Control independent of the main air blower is possible, and optimal control can be performed in consideration of the power supply capacity and the like.

In this case, a sensor for detecting the degree of contamination in the passenger compartment is provided, and the control means determines that the operation stop state of the vehicle is determined by the operation stop state determination means , and the degree of contamination detected by the sensor is not less than a predetermined value. In this case, the ion generator may be operated (Claim 3) . If the degree of contamination detected by the sensor falls below a predetermined level, or the capacity of the power source that supplies power to the ion generator. The ion generator may be deactivated when the value becomes equal to or less than a predetermined value (claim 4) .

The operation time of the ion generator may be determined based on a capacity of a power source that supplies power to the ion generator and a degree of contamination in the vehicle interior immediately before the vehicle is stopped. (Claim 5) .

Further, the operation stop state judging means is that the ignition switch that makes it easy to grasp the passenger's getting off is off, the vehicle speed is below a predetermined speed, the side brake is activated, the shift lever is neutral or parking.

In such a configuration, an operation state determination unit that determines the operation state of the vehicle is provided, and the sub-blower is stopped in the control unit when the operation state of the vehicle is determined by the operation state determination unit. Further, a configuration may be added in which the air blowing path of the main air blower is secured by the switching damper, the air passage of the sub air blower is blocked, and the restriction of the passage cross section of the air blowing path by the sub damper is released. 9).

  According to such a configuration, when the vehicle is stopped, the passage cross section of the air flow path on the upstream side of the ion generator is limited. Therefore, even if the air volume of the sub air blower is reduced, the wind speed at the ion generator is reduced. Can be ensured, and long-time operation is possible even with the same power source capacity.

For this reason, it becomes possible to disinfect and deodorize the vehicle interior effectively, and it is possible to improve the function and effect of the plasma cluster. In addition, since the blower used when the vehicle is stopped can be set independently of the blower used in normal air conditioning control, the generation of ozone odor can be suppressed, and optimal control taking into account the power supply capacity and operating time is possible.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best embodiment of the present invention will be described below with reference to the accompanying drawings.

  In FIG. 1 (a), the vehicle air cleaning device 1 is capable of generating negative ion particles and positive ion particles by plasma discharge, and generates a positive ion particle and a negative ion particle at a substantially equal ratio. And an ion generator 2 that can be switched between a refresh operation mode that increases the generation rate of negative ion particles compared to the first operation mode, an LED display unit 3 that displays an operation state, and the like, The ECU 5 includes a gas sensor 4 for detecting the gas concentration and an ECU 5 for controlling the ion generator 2 and the LED display unit 3. The ECU 5 includes a central processing unit (CPU) and a read-only memory (ROM) (not shown). A random access memory (RAM), an input / output port (I / O), etc., and an ion generator 2 and an LED display 3 It has a Gosuru control circuit.

  The ECU 5 is an on / off determination that determines whether or not an operation signal (FAN ON signal) of a blower mounted on the vehicle air conditioner is input in order to link the air purifier with the operation / non-operation of the vehicle air conditioner (HVAC). Corresponding to the gas concentration detected by the gas sensor 4, the circuit 6, the power supply circuit unit 7 that receives power from a vehicle power source such as a battery and drives the apparatus and supplies power to the LED display unit 3 and the gas sensor 4. And an odor determination unit 8 for determining the odor state of the air. Based on the presence or absence of the FAN ON signal, the signal from the gas sensor 4, etc., the operation / stop of the ion generator 2 and the operation mode are provided. And the display state of the LED display unit 3 are controlled.

  As shown in FIG. 1B, the power source includes a battery 10, an alternator 11, and a solar cell 12 connected in parallel to an electric load Z such as an ion generator 2 or an ECU 5 of the air cleaning device 1. The alternator 11 and the solar battery 12 are configured to charge the battery 10 and supply electric power to the electric load Z together with the battery 10.

  The ion generator 2 of the air cleaning device 1 configured as described above is provided with a blowout duct of an air conditioner mounted on a vehicle, in this example, as shown in FIG. 2, of the side vent duct 20 on the driver side. The air outlet 21 is provided.

Specifically, as shown in FIG. 2A, the ion generator 2 is disposed at the outlet (in this example, the side vent outlet 21) opened in the passenger compartment, and upstream of the ion generator 2. A mode door in which a blower (hereinafter referred to as a main blower) 22 of an air conditioner (HVAC: detailed configuration is omitted) that supplies conditioned air to the passenger compartment is provided on the side, and this blower outlet is provided on the outlet side of the air conditioner (In this example, the side vent door) 23 is opened and closed. Such a configuration is referred to as a first blowing configuration (reference configuration) .

  Moreover, the above blow-out structure is good also as a structure as shown by FIG.2 (b). In other words, an ion generator 2 is arranged at an outlet (in this example, a side vent outlet 21) opened in the passenger compartment, and an air conditioner (HVAC) supplies conditioned air to the passenger compartment upstream of the ion generator 2. : The detailed blower is omitted) 22 (hereinafter referred to as a main blower) and a sub blower 24 provided separately from the main blower 22 are arranged, and air is blown downstream of the main blower 22 and the sub blower 24. A main damper 25 that constitutes a switching damper that switches the route is disposed. In such a configuration, by setting the position of the main damper 25 to a position that shields the downstream side of the sub-blower 24 (by setting it to the position II in the figure), the air conditioning equipment (not shown) of the HVAC from the main blower 22 In addition, a main air passage 26 leading to the air outlet 21 through the ion generator 2 is formed, and the main damper 25 is set to a position that shields the downstream side of the main air blower 22 (set to the I position in the figure). Thus, a sub-air passage 27 is formed that leads from the sub-air blower 24 directly to the air outlet 21 via the ion generator 2.

Further, in this configuration, a sub-damper 28 is provided between the ion generator 2 and the sub-blower 24 so that the passage area of the blower path can be restricted, and the position of the sub-damper 28 is restricted by restricting the passage area. The position can be switched between an I position for reducing the passage area toward the ion generator side and an II position for forming a state in which the passage area is not limited. Such a blowing configuration shown in FIG. 2B is a second blowing configuration ( configuration according to the present invention) .

The above-described main blower 22, sub blower 24, main damper 25, and sub damper 28 are also objects to be controlled by the ECU 5, and the control by the ECU 5 is performed based on the flowchart shown in FIG. Hereinafter, an example of the control operation of the air cleaning device 1 will be described based on this flowchart. The ECU 5 executes this processing routine through a predetermined initial setting process after turning on the ignition switch. Signal (vehicle speed signal), side brake signal output when the side brake is activated, signal corresponding to the position of the shift lever (shift lever signal), output signal from the seating sensor that detects the presence or absence of a passenger, air conditioning panel An output signal or the like is input, and in step 52, the vehicle state is determined (SUB1). As shown in FIG. 4, the determination of the vehicle state is to determine whether the vehicle is in a stopped state or a state in which the stopped state is released. In step 100, the vehicle speed is determined from the input vehicle speed signal. In step 102, it is determined whether the supply of conditioned air is OFF (stopped), the vehicle speed is equal to or lower than the predetermined value, and the air conditioner is turned off. When it is determined that the vehicle is in a state, the vehicle is determined to be stopped (step 104). On the other hand, when the vehicle speed is higher than a predetermined value, or when it is determined that the air conditioner is in an operating state (not in an OFF state) even if the vehicle speed is equal to or lower than the predetermined value, the vehicle is stopped. It is determined that it has been released (step 106).

After the vehicle state is determined as described above, in step 54, it is determined whether or not the vehicle state is a stop state. If it is determined that the vehicle state is not the stop state, the process proceeds to step 56 and is performed when the vehicle is in operation. The normal control shown in FIG. 5 is performed (SUB2). Here, the normal control determines in step 200 whether or not the air conditioner is operating based on whether or not the main blower 22 is in an ON (operating) state, and if it is determined that the main blower 22 is not in an ON state. The ion generator cannot be supplied to the passenger compartment, and ozone may be generated when the ion generator 2 is operated in a windless state. Therefore, the ion generator 2 is stopped (step 202).

On the other hand, if it determines with the main air blower 22 being an ON (operation) state, the ion generator 2 will be set to an ON (operation) state (step 204). Then, based on the output from the gas sensor 4, it is determined whether or not the degree of dirt in the passenger compartment is equal to or less than a predetermined value (step 206). The ion generator is operated in a clean operation mode that generates at a ratio (step 208). If the degree of contamination is below a predetermined level, ions are generated in a refresh operation mode that increases the generation rate of negative ion particles compared to the clean operation mode. The device is activated (step 210).

  By the way, when it is determined in step 54 that the vehicle state is the stop state, it is determined based on the output from the gas sensor 4 whether or not the degree of dirt in the passenger compartment is greater than or equal to a predetermined value (step 58). If the degree of contamination in the passenger compartment is not greater than or equal to a predetermined level, the passenger compartment is not required to be cleaned. Therefore, the process proceeds to step 60, where the blower is set to the OFF (stopped) state. Is set to the OFF (stopped) state, and in the second blowing configuration, the sub-blower 24 is set to the OFF (stopped) state), and the operation of the ion generator 2 is set to the OFF (stopped) state. The cleaning device 1 is stopped. On the other hand, if it is determined in step 58 that the degree of dirt in the passenger compartment is greater than or equal to the predetermined level, in step 62, the mode actuator (mode ACT) that drives the mode door 23 is used in the first blowout configuration. ) Is controlled to open the outlet 21 where the ion generator 2 is disposed (SUB3), and in the second outlet configuration, the main damper 25 and the sub damper 28 are driven and controlled (SUB4), and the next step At 66, the ion generator 2 is driven and controlled (SUB5).

  Here, as shown in FIG. 6, the drive control of the mode actuator of the SUB 3 drives the mode door 23 toward the open position where the ion generator 2 is disposed (step 300). Is stopped when it coincides with the target position (not necessarily fully open) for opening the outlet (steps 302 and 304).

  Further, in the damper drive control of the SUB 4, as shown in FIG. 7, the main damper 25 and the sub damper 28 are driven toward the I position in FIG. 2B (step 400), and the position of each damper is II. If it matches the position, it is stopped (steps 402 and 404). That is, the main damper 25 is set to a position where the downstream side of the main blower 22 is shielded, and the sub damper 28 is set to a position that limits the passage area of the blowing path.

  As shown in FIG. 8, the SUB5 ion generator drive control determines whether or not the power supply voltage is not more than a predetermined value (step 500), and whether or not the degree of dirt in the vehicle interior is not more than a predetermined value. Determination is made (step 502). If the power supply voltage is not more than a predetermined value, the capacity is insufficient to operate the ion generator 2, and if the degree of dirt in the passenger compartment is not more than a predetermined value, it is not necessary to clean the passenger compartment. FLG) is set to 1 (step 504), and in either case, the blower is stopped (in the first blowing configuration, the main blower 22 is set to the OFF state, and in the second blowing configuration, the auxiliary blower is set to the secondary blowing configuration). The blower 24 is set to the OFF state), and the ion generator 2 is stopped (step 506). On the other hand, if the power supply voltage is not lower than the predetermined value and the degree of dirt in the vehicle interior is higher than the predetermined value, the process proceeds to step 508 to determine whether or not the stop flag is set. Then, the stopped state is maintained until the stopped state of the vehicle is released (step 506). If not set, the blower is operated (the main blower 22 is set to the ON state in the first blowing configuration). In the second blowing configuration, the sub blower 24 is set to the ON state), and the ion generator 2 is operated (step 510).

  Therefore, according to the above configuration, when it is determined that the vehicle is in a stopped state where the passenger is expected to get off, and when the degree of dirt in the passenger compartment is determined to be greater than or equal to a predetermined level, The blower outlet in which the ion generator 2 is arranged is opened, the main blower 22 and the ion generator 2 are operated, and positive and negative ion particles are supplied to the passenger compartment. Further, in the second blowing configuration, the main damper 25 is set at a position where the downstream side of the main blower 22 is closed to form the sub blow path 27, the sub blower 24 and the ion generator 2 are operated, plus and minus Ion particles are supplied to the passenger compartment. Therefore, it becomes possible to supply ion particles to the passenger compartment even when no passenger is present, and it is possible to efficiently disperse the ion particles into the passenger compartment and perform sterilization and deodorization effectively.

  In particular, in the second blow-out configuration, since the ion particles are supplied to the passenger compartment by operating the sub blower 24 different from the main blower 22 when the operation of the vehicle is stopped, the sub blower 24 is supplied with the conditioned air. It is possible to perform control separately from the control of the blower, and it is possible to perform optimal control in consideration of the power supply capacity and the like. Further, since the passage area of the sub-air passage 27 is limited by the sub-damper 28 and the passing air is brought closer to the ion generator side, it is possible to ensure the wind speed in the vicinity of the ion generator even if the air volume of the sub-blower 24 is reduced. As a result, it is possible to suppress the generation of ozone and to reduce the power consumption by the amount that the sub-blower 24 can be set to a small amount of air.

In the above configuration example, the vehicle speed is determined in step 100 as the vehicle state determination. However, whether the side brake is operated, whether the shift lever is set to the neutral position or the parking position, the seating sensor It is also possible to determine at least one of whether an occupant has been detected and whether the ignition switch is off. Further, whether or not the supply of the conditioned air in step 102 is in an OFF state may be determined depending on whether or not the ignition switch is OFF.

  Instead of the above control, as shown in FIG. 9, the process of step 58 determines whether or not the vehicle state has been switched from a state other than the stop to the stop state (step 70), and it has been determined that the vehicle has been switched to the stop state. If not, the process proceeds to step 60, where the blower is stopped and the ion generator is stopped. If it is determined that the ion generator is switched to the stopped state, the detected value of the gas sensor 4 detected immediately before the determination is made. The gas may be stored as a gas sensor memory value gasM (step 72), and the processing after step 62 may be performed. In this case, the ion generator drive control in step 64 may be performed based on the flowchart shown in FIG.

  In FIG. 11, the ion generator drive control determines in step 550 whether or not the power supply voltage is equal to or lower than a predetermined value, and determines whether or not the power supply capacity is insufficient. When it is determined that the power supply voltage is lower than the predetermined value due to insufficient power supply capacity, the stop flag (FLG) is set to 1 (step 552), and the blower is stopped (in the first blowing configuration) The main blower 22 is set to the OFF state, and in the second blowing configuration, the sub blower 24 is set to the OFF state), and the ion generator 2 is stopped (step 554). On the other hand, when it is determined that the power supply capacity is sufficient and the power supply voltage is not less than the predetermined value, the corrected operation time (α) of the ion generator 2 is calculated from the power supply voltage based on a prestored map. (Step 556).

  Thereafter, it is determined whether or not the degree of dirt in the passenger compartment is equal to or less than a predetermined value (step 558). If it is equal to or lower than the predetermined value, it is not necessary to clean the passenger compartment, so the process proceeds to step 552 and a stop flag (FLG) is set. In step 554, the blower is turned off and the ion generator 2 is stopped.

  If it is determined in step 558 that the degree of dirt in the passenger compartment is greater than or equal to the predetermined level, the process proceeds to step 560, where it is determined whether or not a stop flag is set, and if it is determined that it is set. In Step 554, the blower is turned off and the ion generator 2 is stopped. On the other hand, if it is determined that the stop flag is not set, the routine proceeds to step 562, where the detected value of the gas sensor 4 or the degree of dirt in the vehicle compartment immediately before the transition to the stop state stored in step 72 is made. Based on the above, the correction operation time (β) of the ion generator 2 is calculated from a previously stored map.

  Thereafter, the operation time T1 of the ion generator 2 is calculated by adding the correction operation time (α) calculated in step 556 and the correction operation time (β) calculated in step 562 to the operation reference time t1. (Step 564). Then, the timer T is started to start measuring time (step 566), and it is determined whether or not the operation time calculated in step 564 has elapsed since the start of measuring time (step 568). If it is determined that T1 has elapsed after the start of timing, the timer T is reset (step 570), the blower is turned off and the ion generator 2 is stopped (step 554), until T1 elapses. The blower is turned on (the main blower 22 is set to the ON state in the first blowing configuration, and the secondary blower 24 is set to the ON state in the second blowing configuration), and the ion generator 2 is operated. In this manner, sterilization and deodorization in the passenger compartment are attempted (step 572).

  Therefore, even in such a configuration, when it is determined that the vehicle is in a stopped state where the passenger is expected to get off, and when it is determined that the degree of dirt in the passenger compartment is greater than or equal to a predetermined level, The blower outlet in which the ion generator 2 is arranged is opened, the main blower 22 and the ion generator 2 are operated for a predetermined time T1, and positive and negative ion particles are supplied to the passenger compartment. Further, in the second blowing configuration, the main damper 25 is set at a position where the downstream side of the main blower 22 is closed to form the sub blow path 27, and the sub blower 24 and the ion generator 2 operate for a predetermined time T1, Positive and negative ion particles are supplied to the passenger compartment. Therefore, it becomes possible to discharge the ion particles to the passenger compartment even when the occupant is absent, and it is possible to efficiently disperse the ion particles into the passenger compartment and perform sterilization and deodorization effectively. Moreover, in this configuration example, the air purifier does not continue to operate until the vehicle stop state is released, and the operation time is determined according to the capacity of the power source and the degree of dirt in the vehicle interior. After the air is cleaned, the air purifier is not operated unnecessarily.

  In particular, in the second blow-out configuration, as described above, the ion blower 24 is operated by operating the auxiliary blower 24 different from the main blower 22 when the operation of the vehicle is stopped. Therefore, it is possible to control the main blower separately from the control of the main blower supplying the air, and it is possible to perform optimal control in consideration of the power supply capacity and the like. Further, since the passage area of the sub-air passage 27 is limited by the sub-damper 28 and the passing air is brought closer to the ion generator side, it is possible to ensure the wind speed in the vicinity of the ion generator even if the air volume of the sub-blower 24 is reduced. As a result, it is possible to suppress the generation of ozone and to reduce the power consumption by the amount that the sub-blower 24 can be set to a small amount of air.

  The present invention is an air cleaning device suitable for efficiently cleaning a passenger compartment in which a person gets on and off using a plasma cluster, and efficiently cleans the space of a moving body having a narrow space where a person enters and exits. It is also applicable to.
