Disclosure of the invention

[0003] However, the conventional air conditioner described above has the following problems. That is, when the conventional air conditioner receives an instruction input to perform a powerful operation. As described above, the power that is controlled to increase the operating frequency of the compressor, the number of revolutions of the fan, etc., and that improves the air conditioning processing capacity. The blowing direction was not controlled at all, and the direction of air flow was determined by the direction of the wind direction adjustment plate when a powerful operation instruction was input.

Therefore, for example, when a powerful operation instruction is input during cooling, a larger amount of cold air is supplied to the room than during normal cooling operation, but this air is completely different from the direction in which people are present. When supplied in the direction, the user cannot feel that the powerful driving is being performed. Conversely, for example, if a powerful operation instruction is input during cooling, the air-conditioned air is supplied to the room with the processing capacity increased.This air may directly hit people. Yes, for example, during the cooling and powerful operation, there is a possibility that the occupants may feel uncomfortable, such as excessive cooling.

An object of the present invention is to provide an air conditioner capable of controlling the direction of air-conditioned air blowing during a powerful operation, and a control method thereof.

In a conventional air conditioner, only the processing capacity of the air conditioner is temporarily improved during the powerful operation, and the direction of air blowing at that time is not controlled. For this reason, the direction of the wind direction adjustment plate during the powerful operation was determined based on the outcome of the direction of the wind direction adjustment plate immediately before the instruction input of the powerful operation was performed. Therefore, for example, even when the powerful operation is performed during the same cooling, the direction of the wind direction adjustment plate may differ depending on the immediately preceding operation condition.

Therefore, in the air conditioner of the present invention, the following effects can be obtained by controlling the direction of the wind direction adjustment plate even during the powerful operation.

That is, in the air conditioner of the present invention, when an instruction for powerful operation is input, the presence of a person is reduced.

Fig. 2 shows a system diagram of the refrigerant circuit used in the air conditioner 1.

Inside the indoor unit 2, an indoor heat exchanger is provided. The indoor heat exchanger is composed of a heat transfer tube bent a plurality of times at both ends in the longitudinal direction, and a plurality of fins through which the heat transfer tube is inserted. The indoor heat exchange 11 exchanges heat with the air that comes into contact with the air. A cross-flow fan (air conditioning mechanism) 12 is provided in the indoor unit 2 for sucking indoor air and exchanging heat with the indoor heat exchanger 11 to blow out the air into the room. ing. The cross flow fan 12 is formed in a cylindrical shape, and its peripheral surface is provided with blades in the rotation axis direction. Then, the cross flow fan 12 is emptied in a direction intersecting the rotation axis. Generates airflow. The cross flow fan 12 is driven to rotate by a fan motor 13 provided in the indoor unit 2.

The outdoor air-conditioning unit 5 includes a compressor (air conditioning mechanism) 21, a four-way switching valve 22, an accumulator 23, an outdoor heat exchanger 24, and a pressure reducer 25 (see FIG. 2). The four-way switching valve 22 is connected to the discharge side of the compressor 21. The accumulator 23 is connected to the suction side of the compressor 21. The outdoor heat exchange 24 is connected to the four-way switching valve 22. The pressure reducer 25 is an electric expansion valve connected to the outdoor heat exchanger 24. The pressure reducer 25 is connected to a pipe 31 via a filter 26 and a liquid shutoff valve 27, and is connected to one end of the indoor heat exchanger 11 via the pipe 31. Furthermore, the four-way switching valve 22 is connected to a pipe 32 via a gas closing valve 28, and is connected to the other end of the indoor heat exchanger 11 via the pipe 32. The pipes 31 and 32 correspond to the refrigerant pipe 6 in FIG.

FIG. 3 is a cross-sectional view of the indoor unit 2. The indoor heat exchange 11 and the cross flow fan 12 described above are accommodated in a casing 14 of the indoor unit 2. The indoor heat exchanger 11 is attached so as to surround the front, the upper part, and the upper rear part of the cross mouth opening fan 12. The indoor heat exchange ^^ 11 is sucked by the drive of the cross flow fan 12, sucked through the inlet 142, and allows the inserted air to pass through the cross flow fan 12 to the refrigerant passing through the heat transfer tube. Allow heat exchange.

Below the indoor heat exchanger 11, a drain pan 141 for receiving water droplets generated on the surface of the indoor heat exchanger 11 during heat exchange is provided. The drain pan 141 is provided with a drain hose (not shown) for discharging the received water drops to the outside. The drain pan 141 is configured to receive such water droplets and drain the water droplets by a drain hose.

In the upper part of the casing 14, a suction port 142 composed of a plurality of slit-shaped openings is provided. An outlet 143 having a long opening force in the longitudinal direction of the indoor unit 2 is provided at a lower portion of the casing 14. Further, the outlet 143 is provided with a horizontal flap (upper / lower flap) 144 for determining a blowing direction of air blown into the room by the cross flow fan 12. The horizontal flap 144 is provided rotatably about a shaft 145 parallel to the longitudinal direction of the indoor unit 2. The horizontal flap 144 is By being rotated by the promoter 146 (see FIG. 7), it is possible to determine the air blowing direction. As shown in FIG. 4, when the end portion 144a of the horizontal flap 144 faces substantially in the horizontal direction, the conditioned air is blown out in a substantially horizontal direction. In addition, as shown in FIG. 5, when the end portion 144a of the horizontal flap 144 faces substantially vertically downward, the conditioned air is blown substantially vertically downward. Furthermore, as shown in FIG. 6, when the operation of the air conditioner 1 is stopped, the end 144a of the horizontal flap 144 contacts the end of the casing 14. In this case, the horizontal flap 144 covers the outlet 143 almost completely.

In the outdoor air conditioning unit 5, a propeller fan 29 for discharging the air after the heat exchange in the outdoor heat exchanger 24 to the outside is provided. The propeller fan 29 is driven to rotate by a propeller fan motor 30.

The air conditioner 1 further includes a control unit 60.

As shown in FIG. 7, the control unit 60 is connected to the compressor 21, the four-way switching valve 22, the pressure reducer 25, the ROM 41, the RAM 42, the fan motor 13, the flap motor 146, the temperature sensor 43, and the infrared sensor 44. I have. Further, the control unit 60 communicates with the remote controller 40, and limits the time of the powerful operation by the timer 45 working inside the program. Further, the control unit 60 controls the compressor 21, the four-way switching valve 22, the pressure reducer 25, the fan motor 13, and the flap motor 146.

The ROM 41 stores a control program and various parameters. The ROM 41 further stores the set air volume at the time of various settings, the position of the horizontal flap 144 at the time of the powerful operation setting, the swing range, and the like.

The set air volume is a driving air volume that determines the air volume of the air blown out from the outlet 143, and specifically, “Shizuka”, “Breeze”, “Weak”, “Weak”, “Weak”, “ Strong winds ”. “Shizu Power” indicates the operating airflow with the smallest airflow, and “Strong Wind” indicates the operating airflow with the largest airflow. The control unit 60 selects one of the set airflows based on a signal from the remote controller 40 described later, and stores the selected set airflow in the RAM 42. Then, the control unit 60 rotates the fan motor 13 so as to blow the conditioned air in an amount corresponding to the selected set air volume into the room. The remote controller 40 is an operation device for transmitting an instruction of the occupant to the air conditioner 1 and operating the air conditioner 1 in response to a request of the occupant. The occupants can use the remote controller 40 to set the room temperature, ONZOFF the swing function of the horizontal flap 144, select the swing mode, and input an instruction for a no-full operation.

Here, the powerful operation refers to temporarily increasing the rotation speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like by temporarily inputting an instruction from a user, thereby temporarily improving the air conditioning processing capacity. Can be done. The details of this powerful operation will be described later.

These instructions are transmitted from the remote controller 40 to the control unit 60, and are used for controlling each component. These instructions are transmitted from the control unit 60 to the RAM 42 together with the result of human detection by the infrared sensor 44 (information on the direction in which a person is present) and stored in the RAM 42.

Further, the target temperature T by operating the air conditioner 1 can be set using the remote controller 40. The target temperature T is transmitted from the remote controller 40 to the control unit 60, and is used for controlling each component. The target temperature T is sent from the control unit 60 to the RAM 42 and stored in the RAM 42. For example, when the room temperature is lower than the target temperature T by a predetermined temperature (tl) or more during the cooling operation, the control unit 60 stops the operation of the compressor 21 in order to suppress the energy consumption of the air conditioner 1. . On the other hand, when the room temperature exceeds the target temperature T by a predetermined temperature t2 or more due to the stop of the compressor 21, the control unit 60 operates the compressor 21 again.

The temperature sensor 43 is provided in the indoor unit 2 and measures the indoor temperature. The temperature sensor 43 transmits the measured room temperature to the control unit 60.

The infrared sensor (sensor) 44 is provided near the surface of the indoor unit 2 and is a human detection sensor that detects a person in the room. The infrared sensor 44 transmits information on the direction in which the sensed person is to the control unit 60. It should be noted that the human detection using the infrared sensor 44 may be performed so as to be always performed, or may be performed at predetermined time intervals.

The following describes the powerful operation of the air conditioner 1 during cooling operation and heating operation. Will be explained.

For example, if the user inputs an instruction to perform a powerful operation from the remote controller 40 during the cooling operation, the control unit 60 of the air conditioner 1 increases the rotation speed of the cross flow fan 12 to improve the air conditioning processing capacity. In addition to controlling the fan motor 13, the operating frequency of the compressor 21 is controlled.

In the air conditioner 1 of the present embodiment, the control unit 60 controls the direction of the horizontal flap 144 in addition to the above control, particularly when an instruction input for a powerful operation is received. For example, during normal cooling operation, air conditioned in a substantially horizontal direction is blown into the room S as shown in FIG. Here, when there is a command input for the powerful operation, heat is exchanged by the indoor heat exchanger 11 in the direction where the person is present, as shown in FIG. 8 (b), according to the detection result from the infrared sensor 44. The horizontal flap 144 is adjusted by controlling the flap motor 146 so that the blown air is blown out.

Therefore, no matter which direction the horizontal flap 144 is directed during the operation before the instruction input of the full operation, the human operator always receives a! / ヽ command when the instruction input of the powerful operation is input. The direction of the horizontal flap 144 is controlled so as to change the direction. Therefore, the user can feel the powerful feeling by the powerful operation by directly receiving the air-conditioned air by the instruction input of the powerful operation.

Such a powerful operation is also performed during the heating operation.

The powerful operation temporarily increases the air conditioning processing capacity of the air conditioner 1, and the time during which the powerful operation is performed is limited by the timer 45. The timer 45 receives the powerful operation instruction input from the user by the control unit 60 and starts measuring the time of the force, and sends a signal to the control unit 60 when a predetermined time comes. When receiving the signal from the timer 45, the control unit 60 controls the fan motor 13, the compressor 21 and the flapper motor 146 to return to the original normal operation state, terminates the powerful operation, and returns to the normal operation state.

In the air conditioner 1 of the present embodiment, the timer 45 sets a time period during which the air does not condense near the outlet 143 even when air is directly blown near the outlet 143 during the cooling powerful operation as a set time. Has been entered.

With this, no matter which direction the horizontal flap 144 faces during the cooling powerful operation, The problem of dew formation near the outlet 143 can be reliably prevented by setting a time limit.

(1)

In the air conditioner 1 of the first embodiment, when an instruction to perform a powerful operation is input from the remote controller 40, the rotation speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like are temporarily increased to perform the air conditioning process. The ability is improved and the wind direction is controlled.

Even in a conventional air conditioner, when an instruction input power S that temporarily increases the processing capacity is input, the rotation speed of the fan, the operating frequency of the compressor, and the like have been increased. However, at this time, the power was not controlled up to the direction of the air supplied into the room, so the wind direction was determined by the direction of the horizontal flap immediately before the instruction for the powerful operation was input.

Therefore, in the air conditioner 1 of the present embodiment, the processing capacity is temporarily increased, that is, the direction of the horizontal flap 144 is controlled even during the so-called full operation, so that the air conditioning is performed with the operation ability improved. Air can be blown out in a desired direction.

In particular, in the air conditioner 1 of the present embodiment, the direction of the horizontal flap 144 is controlled so that the air-conditioned air is blown out toward the direction of the person in the room.

Accordingly, when the user sets the powerful operation, the air-conditioned air is blown out toward the user, so that the user can feel a powerful feeling at the time of the powerful operation.

(2)

The air conditioner 1 of the first embodiment uses the infrared sensor 44 to detect the direction in which a person is indoors.

Accordingly, the direction of the horizontal flap 144 can be adjusted so that the wind directly hits the person regardless of the position of the person in the room.

(3)

In the air conditioner 1 of the first embodiment, when a power operation instruction is input, the direction of the horizontal flap 144 is fixed, and air-conditioned air is blown out in a direction where a person is present. As a result, it is possible to make the user in the room feel a powerful feeling at the time of the powerful driving.

(Four)

In the air conditioner 1 of the first embodiment, the time for performing the powerful operation using the timer 45 is limited.

This makes it possible to control the powerful operation as temporarily increasing the air conditioning capacity.

(Five)

In the air conditioner 1 of the first embodiment, the set time of the timer 45 is set so that dew condensation does not occur near the outlet 143 of the indoor unit 2!

Ordinarily, when the horizontal flap 144 is directed in the direction where a person is present in the powerful operation during cooling, air-conditioned air may also hit the vicinity of the outlet. In such a case, if cold air is continuously blown for a long time, dew condensation may occur near the outlet.

Therefore, in the air conditioner 1 of the present embodiment, by limiting the time during which the horizontal flap 144 faces the direction, dew condensation near the outlet 143 can be reliably prevented.

The air conditioner 1 of the first embodiment uses the horizontal flap 144 to control the direction in which the air supplied to the room is blown out.

As a result, compared to the case where the direction of the vertical flap is controlled, by using the horizontal flap 144 that adjusts the wind direction in the vertical direction, air can be easily blown out in the direction where people are present. it can.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said Embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

(A)

In the first embodiment, an example has been described in which the direction in which a person is present is detected using the infrared sensor 44, and air-conditioned air is blown in that direction during a powerful operation. But, The present invention is not limited to this. For example, air-conditioned air may be blown out to a specific range that is assumed to be a person's location without using a sensor.

Also, the sensor is not limited to the infrared sensor as long as it can detect the location of a person, and another sensor may be used.

(B)

In the first embodiment, an example has been described in which the direction of the horizontal flap 144 is fixed in a direction where a person is present during the powerful operation. However, the present invention is not limited to this. For example, as shown in FIG. 9 (a), during normal cooling operation, when the horizontal flap 144 swings between the substantially horizontal direction and During driving, as shown in FIG. 9 (b), the horizontal flap 144 may be swung by extending the swing range to include the direction where the person is. Even in this case, since the user can directly feel the air blown out during the powerful operation, it is possible to make the user feel a powerful feeling similarly to the case where the horizontal flap 144 is fixed so as to face the direction where the person is. it can.

(C)

In the first embodiment, an example has been described in which the direction of the horizontal flap 144 is controlled and the air-conditioned air is blown into the room during the powerful operation in the vertical direction in which a person is present. However, the present invention is not limited to this. For example, the wind direction may be controlled in the left-right direction using the vertical flap, or the wind direction may be controlled using both the vertical flap and the horizontal flap 144.

(D)

In the first embodiment, when an instruction to perform a powerful operation is input regardless of whether the air conditioner is in the cooling mode or the heating mode, the direction of the horizontal flap 144 is controlled so as to blow out the air-conditioned air in the direction of the person. The example has been described. However, the present invention is not limited to this. For example, the control of the direction of the horizontal flap 144 may be limited so that the air-conditioned air is blown out in the direction in which a person is present only when a powerful driving instruction is input during cooling.

This allows the user to feel a feeling of coolness in the powerful operation during cooling, and further enhances the power. You can feel the powerful feeling when driving.

(E)

In the first embodiment, an example has been described in which the time during which the powerful operation is performed is limited by the timer 45. However, the present invention is not limited to this. For example, a time for fixing the direction of the horizontal flap 144 during the powerful operation may be set in the timer 45. In this case, the horizontal flap 144 fixed at a predetermined angle during the powerful operation is controlled to swing after the time limit set in the timer 45 elapses.

[Second Embodiment]

In the air conditioner according to the second embodiment, the control unit 60 controls the flap motor 146 so as to blow out the air subjected to the heat exchange processing (air conditioning) by the indoor heat exchanger 11 in a direction where no one is present. It differs from the air conditioner according to the first embodiment in that the direction of 144 is adjusted. Therefore, only the operation of the air conditioner during the powerful operation is described here.

Hereinafter, the powerful operation of the air conditioner 1 during the cooling operation and the heating operation will be described.

In the air conditioner 1 of the second embodiment, in particular, when an instruction input for a powerful operation is received, the control unit 60 controls the direction of the horizontal flap 144 by performing the control described in the first embodiment. For example, it is assumed that, during the cooling operation, air whose air is conditioned in a substantially horizontal direction with a slightly downward airflow is blown into the room S as shown in FIG. Here, if there is a command input for the full operation, the indoor heat exchanger 11 performs heat exchange processing (in the direction where no one is present) according to the detection result from the infrared sensor 44, as shown in FIG. 10 (b). Air conditioning) Controls the flap motor 146 to blow out the air that has been adjust.

In this way, the direction of the horizontal flap 144 during the operation before the instruction input of the full driving is inputted, and even if the instruction of the powerful driving is input, the direction in which no person is present is always present. The horizontal flap 144 is controlled so as to change its direction. Therefore, even if the occupant inputs a command for a full operation, the occupant can comfortably stay in the room without feeling excessive cooling feeling due to direct wind blow during cooling.

Such a powerful operation is also performed during the heating operation.

The powerful operation temporarily increases the air conditioning processing capacity of the air conditioner 1, and the time during which the powerful operation is performed is limited by the timer 45. The timer 45 receives the powerful operation instruction input from the user by the control unit 60 and starts measuring the time of the force, and sends a signal to the control unit 60 when a predetermined time comes. Upon receiving the signal from the timer 45, the control unit 60 controls the fan motor 13, the compressor 21, and the flap motor 146 to return to the original normal operation state, terminate the powerful operation, and return to the normal operation state .

(1)

When an instruction to perform a powerful operation is input from the remote controller 40, the air conditioner 1 according to the second embodiment temporarily increases the rotation speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like, thereby controlling the air conditioner. The processing capacity is improved and the wind direction is controlled.

Even in a conventional air conditioner, when an instruction input power S that temporarily increases the processing capacity is input, the rotation speed of the fan, the operating frequency of the compressor, and the like have been increased. However, at this time, since the power was not controlled up to the direction in which the air supplied into the room was blown out, the wind direction was determined based on the outcome of the direction of the horizontal flap 144 immediately before the instruction for the powerful operation was input. As a result, after the start of the powerful operation, the horizontal flap 144 was directed in the direction of the person, and the air-conditioned air hit the person directly, which sometimes caused discomfort to the person.

Therefore, in the air conditioner 1 of the present embodiment, the processing capacity is temporarily increased, that is, the direction of the horizontal flap 144 is controlled even during the so-called full operation, so that the air conditioning is performed with the operation ability improved. Air can be blown out in a desired direction. In particular, in the air conditioner 1 of the present embodiment, the direction of the horizontal flap 144 is controlled so as to blow out the air-conditioned air while avoiding the direction where the person is.

Thereby, when the user sets the powerful operation, the air-conditioned air is blown out in a direction other than the direction where the person is present, for example, near the ceiling. Therefore, for example, even if a powerful operation is installed during cooling, it is possible to prevent direct cold air from directly hitting a person, and thus it is possible to perform a powerful operation without giving discomfort due to excessive cooling sensation .

(2)

The air conditioner 1 of the second embodiment uses an infrared sensor 44 to detect the direction in which a person is indoors.

Accordingly, the direction of the horizontal flap 144 can be adjusted so that the wind does not directly hit the person regardless of the position of the person in the room.

(3)

In the air conditioner 1 of the second embodiment, when a power operation instruction is input, the direction of the horizontal flap 144 is fixed, and air that is air-conditioned in a direction where no one is present is blown out. Thereby, for example, it is possible to prevent a user in the room from being discomforted by an excessive cooling sensation caused by direct hitting of a cold wind during cooling.

(Four)

In the air conditioner 1 of the second embodiment, the time during which the powerful operation is performed is limited by using a timer 45 that operates inside the program.

(Five)

The air conditioner 1 according to the second embodiment uses the horizontal flap 144 to control the blowing direction of the air supplied to the room.

As a result, compared to the case of controlling the direction of the vertical flap, the control is performed using the horizontal flap 144 that adjusts the wind direction in the vertical direction, so that the air can be easily blown out in a direction where no one is present. Can be. <Modification of the second embodiment>

(A)

In the second embodiment, an example has been described in which the direction of the horizontal flap 144 is fixed in a direction where no one is present during the powerful operation. However, the present invention is not limited to this. For example, as shown in Fig. 11 (a), when the horizontal flap 144 is swinging downward from the horizontal direction by several degrees during the cooling operation, as shown in Fig. As described above, the horizontal flap 144 may be swung within a range not including the direction in which the person is. Even in this case, the user does not directly hit the air blown out during the powerful operation, so that the user does not feel discomfort as in the case where the horizontal flap 144 is fixed so that the person is present and facing the direction. Powerful operation can be performed.

(B)

In the second embodiment, an example has been described in which the direction of the horizontal flap 144 is controlled and the air-conditioned air is blown into the room during the powerful operation in the vertical direction where no one is present. However, the invention is not so limited. For example, the wind direction may be controlled in the left-right direction using a vertical flap or both the horizontal flap 144 and the vertical flap.

(C)

In the second embodiment, regardless of cooling or heating, when an instruction is input to perform a powerful operation, the direction of the horizontal flap 144 is controlled so as to blow air-conditioned air in a direction where no one is present. The example has been described. However, the present invention is not limited to this. For example, the control of the direction of the horizontal flap 144 may be limited so that the air-conditioned air is blown out in a direction where no one is present only when a powerful operation instruction is input during cooling.

Industrial applicability

INDUSTRIAL APPLICABILITY The present invention has an effect that the blowing direction of air-conditioned air can be controlled during a powerful operation, so that the present invention can be applied to an air conditioner that can perform a powerful operation during a cooling operation and a heating operation. .
