Description

Air conditioner and its control method {AIR CONDITIONER AND CONTROL METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner capable of performing a powerful operation of temporarily increasing the rotation speed of a fan, the operating frequency of a compressor, and the like to improve air conditioning processing capability, and a control method thereof.

BACKGROUND ART Conventionally, an air conditioner installed in a house, a building, or the like, which improves comfort in an interior by blowing air with air in a room has been known. Such an air conditioner maintains the indoor temperature at a comfortable temperature for the occupants by blowing cold air or warm air into the room, and improves the comfort of the room.

An air conditioner is equipped with the air conditioning indoor unit installed in the room which performs air conditioning, and the air conditioning outdoor unit installed in the outdoors. The air conditioning indoor unit and the air conditioning outdoor unit are connected by a refrigerant pipe, and air conditioning is performed by causing heat exchange between the refrigerant flowing through the refrigerant pipe and the indoor air.

Among such air conditioners, particularly in cooling operation or heating operation, the so-called powerful operation of temporarily raising the operating frequency of the compressor, the fan rotation speed, etc. by the input of instructions from the user, and improving the air conditioning processing capability is performed. There is something to do. By instructing and inputting the powerful operation by the remote control or the like, it is possible to temporarily increase the air conditioning processing capacity of, for example, air conditioning and heating being operated at that time.

<Patent Document 1>

Japanese Patent Laid-Open No. 7-103551

However, the said conventional air conditioner has the problem as shown below.

That is, in the conventional air conditioner, when the instruction input for the purpose of performing the powerful operation is input, as described above, it is controlled to increase the operating frequency of the compressor, the rotation speed of the fan, etc., thereby improving the air conditioning processing capability. The air blowout direction of the air-conditioned air was not controlled at all, and the air blowout direction was determined by the direction of the wind direction control plate when the instruction input of the powerful operation was made.

For this reason, for example, when the instruction input of the powerful operation at the time of cooling is supplied, although a lot of cool air is supplied to a room compared with normal cooling operation, this air is supplied in the direction completely different from the direction of a person. In this case, the user cannot realize that the driving is powerful. In addition, on the contrary, for example, when the instruction input of the powerful operation is performed at the time of cooling, the air-conditioned air is supplied to the room with the processing capability raised, but this air may directly reach a person. For example, in the case of cooling powerful driving, there may be an unpleasant feeling such as excessive cooling for the occupants.

An object of the present invention is to provide an air conditioner and a control method thereof capable of controlling the direction in which air-conditioned air is blown out at the time of powerful operation.

The air conditioner which concerns on 1st invention provides the air conditioning mechanism which performs an air conditioning process with respect to the indoor air, the wind direction adjusting plate which adjusts the blowing direction of air-conditioned air, and raises the processing capability of an air conditioning mechanism temporarily. It is provided with the control part which performs powerful operation. And a control part adjusts the direction of a wind direction adjustment board so that air may blow in the direction of a person at the time of powerful driving.

Here, at the time of powerful operation, not only the processing capacity of the air conditioner including the compressor, the fan, and the like is increased, but also the direction of blowing the air-conditioned air blown into the room is controlled.

In the conventional air conditioner, the processing capacity of the air conditioner is only temporarily improved at the time of powerful operation, and the air blowing direction at that time is not subject to control. For this reason, the direction of the wind direction control board at the time of powerful operation was decided by the direction of the wind direction control board just before the instruction input of powerful operation is performed. Thus, for example, even in the case where the powerful driving is performed during the same cooling, the direction of the wind direction adjusting plate may be different depending on the driving situation immediately before the same.

Therefore, in the air conditioner of this invention, the effect as shown below can be acquired by controlling the direction of a wind direction adjustment board also at the time of powerful operation.

That is, in the air conditioner of this invention, when the instruction input of a powerful operation is input, the direction of the wind direction control board is controlled so that the air-conditioned air blows toward the direction in which a person is located. Thereby, the user who performed the instruction input of powerful driving can receive the air-conditioned air directly in the state in which the processing capability of the air conditioning mechanism was raised, and can feel the powerful feeling of powerful driving. On the contrary, in the air conditioner of the present invention, it is also possible to control the direction of the wind direction adjusting plate so as to blow air that is air-conditioned toward the direction where there is no person when the instruction input of the powerful driving is made. In this way, it is possible to prevent the occupant from giving an unpleasant feeling due to excessive cooling at the time of cooling operation or the unpleasant feeling caused by direct contact with warm air at the time of heating, for example.

The air conditioner which concerns on 2nd invention is an air conditioner which concerns on 1st invention, and a control part adjusts the direction of a wind direction adjustment board so that air may blow in the direction of a person at the time of powerful driving.

Here, the direction of the wind direction control plate is controlled so that, when the instruction input of the powerful driving is input, air-conditioned air is blown toward the direction of the person. Thereby, the user who performed the instruction input of powerful driving can receive the air-conditioned air directly in the state in which the processing capability of the air conditioning mechanism was raised, and can feel the powerful feeling of powerful driving.

The air conditioner which concerns on 3rd invention is an air conditioner which concerns on 1st invention, and a control part adjusts the direction of a wind direction adjustment board so that air may blow out in the direction of no person at the time of powerful driving.

Here, the direction of the wind direction control plate is controlled so as to blow the air-conditioned air toward the direction where there is no person when the instruction input of the powerful driving is input. As a result, it is possible to prevent the occupant from giving an unpleasant feeling due to excessive cooling at the time of cooling operation, or an unpleasant feeling caused by direct contact with warm air at the time of heating.

The air conditioner which concerns on 4th invention is an air conditioner which concerns on any one of 1st invention-3rd invention, The direction is fixed in the wind direction adjustment board at the time of powerful driving | operation.

Here, when the instruction input of the powerful driving is input, the direction of the wind direction adjusting plate is fixed in the direction where a person is. Thereby, it can also make a person feel a powerful feeling fully, and on the contrary, it can also reliably prevent giving a person the unpleasant feeling by excessive cooling at the time of cooling operation.

The air conditioner which concerns on 5th invention is an air conditioner which concerns on any one of 1st invention-3rd invention, The wind direction adjustment board changes a swing range at the time of powerful driving.

Here, even when powerful driving is set during the swing of the wind direction adjusting plate, the range is changed to the swing range of the range where the wind reaches the person. As a result, even when the air is not blown directly to the person before the powerful driving, the air is blown directly to the person by the setting of the powerful driving, so that a feeling of power can be felt. In addition, on the contrary, even when powerful driving is set during the swing of the wind direction adjusting plate, it is possible to change the range to a swing range in which the wind does not reach the human. In this way, even when the air-conditioned air is blown directly to the person before the powerful driving, it is possible to reliably prevent the blowing out of the person directly during the powerful driving.

The air conditioner which concerns on 6th invention is an air conditioner which concerns on any one of 1st invention-5th invention, and is further provided with the timer which limits the time to perform a powerful operation.

Here, the apparatus further includes a timer for limiting the time for performing powerful driving. Thereby, it is possible to improve the air conditioning treatment ability such as air conditioning and heating temporarily. Further, even when the wind direction adjusting plate is adjusted in a direction likely to cause condensation in the vicinity of the ejection opening during continuous operation, the time for performing the powerful operation by the timer is limited. As a result, condensation can be prevented from occurring near the tuyeres. In addition, on the contrary, it is also possible to limit the time for performing the powerful operation and to temporarily improve the air conditioning processing capability such as air conditioning and heating.

The air conditioner which concerns on 7th invention is an air conditioner which concerns on 6th invention, The time which stops a wind direction control plate during powerful operation is set in the timer.

Here, the time which stops a wind direction control plate at a predetermined angle is set to a timer during powerful operation. For this reason, if a predetermined time elapses during powerful driving, the wind direction control plate can be swinged in a range including the direction in which a person is present.

The air conditioner which concerns on 8th invention is an air conditioner which concerns on any one of 1st invention thru | or 7th invention, and a wind direction adjustment board is an up-and-down flap.

Here, the direction of the up-down flap in a wind direction adjustment board is controlled, and it is determined whether to contact a person. For this reason, the wind direction adjustment plate can also be adjusted in the direction which makes it easy to reach a person only by moving a blow-out direction up and down, and can also adjust a wind direction adjustment plate in the direction which does not reach a person on the contrary.

The air conditioner which concerns on 9th invention is an air conditioner which concerns on any one of 1st invention to 8th invention, and further includes the sensor which detects a person.

Here, a sensor for detecting a person in the room is further provided. Thereby, the wind direction can be adjusted so as to surely touch a person at the time of powerful driving, and, conversely, the wind direction can be adjusted so as not to touch a person certainly.

The air conditioner which concerns on 10th invention is an air conditioner which concerns on any one of 1st invention to 9th invention, and adjustment of the direction of a wind direction adjustment board is performed when powerful operation is set at the time of cooling operation. .

Here, the control of the direction of the wind direction control plate at the time of performing the powerful operation is performed only when the powerful operation is inputted, especially at the time of cooling operation. That is, when performing powerful operation at the time of cooling, it controls so that cold wind may reach a person directly. This gives a feeling of cold to a person, and can make it feel more powerful. On the contrary, when performing cooling powerful operation, it can also control so that cold air may not directly contact a person. In this way, it is possible to prevent the person from being uncomfortable due to excessive cold feeling.

The control method of the air conditioner which concerns on 11th invention is equipped with the air conditioning mechanism which performs an air conditioning process with respect to the indoor air, and the wind direction adjusting plate which adjusts the blowing direction of air, and temporarily adjusts the processing capability of an air conditioning mechanism. It is a control method of the air conditioner which performs powerful operation | movement which makes it raise up. At the time of powerful driving, the direction of the wind direction control plate is adjusted by adding the direction in which a person is present.

Here, at the time of powerful operation, not only the processing capacity of the air conditioner including the compressor, the fan, etc. is increased, but also the direction of taking out the air-conditioned air supplied to the room is controlled.

In the conventional air conditioner control method, the processing capacity of the air conditioner is only temporarily improved at the time of powerful operation, and the air blowing direction at that time is not subject to control. For this reason, the direction of the wind direction control board at the time of powerful operation was decided by the direction of the wind direction control board just before the instruction input of powerful operation is performed. Thus, for example, even in the case where the powerful driving is performed during the same cooling, the direction of the wind direction adjusting plate may be different depending on the driving situation immediately before the same.

Therefore, in the control method of the air conditioner of this invention, the effect as shown below can be acquired by controlling the direction of a wind direction adjustment board also at the time of powerful operation.

That is, in the control method of the air conditioner of this invention, when the instruction input of a powerful operation is input, the direction of a wind direction adjustment board is controlled so that air which is air-conditioned may be blown toward the direction in which a person is located. Thereby, the user who performed the instruction input of the powerful driving can receive the air-conditioned air directly in the state in which the processing capability was raised, and can feel the powerful feeling of the powerful driving. On the contrary, in the control method of the air conditioner of the present invention, the direction of the wind direction control plate may be controlled so that the air-conditioned air is blown toward the direction where there is no person when the instruction input of the powerful driving is made. In this way, for example, during cooling operation, it is possible to prevent the occupants from being uncomfortable due to excessive cooling.

The control method of the air conditioner which concerns on 12th invention is the control method of the air conditioner which concerns on 11th invention, and adjusts the direction of a wind direction adjustment board so that air may blow in the direction of a person at the time of powerful driving. .

In the control method of the air conditioner of this invention, when the instruction input of a powerful operation is input, the direction of a wind direction control board is controlled so that air which is air-conditioned may be blown toward the direction in which a person is located. Thereby, the user who performed the instruction input of the powerful driving can receive the air-conditioned air directly in the state in which the processing capability was raised, and can feel the powerful feeling of the powerful driving.

The control method of the air conditioner which concerns on 13th invention is the control method of the air conditioner which concerns on 11th invention, and adjusts the direction of a wind direction adjustment board so that air may blow in the direction of no person at the time of powerful driving | operation. .

Furthermore, the four-way switching valve 22 is connected to the pipe 32 via the gas closing valve 28, and is connected to the other end of the indoor heat exchanger 11 through this pipe 32. These piping 31 and 32 correspond to the refrigerant | coolant piping 6 of FIG.

3 is a cross-sectional view of the indoor unit 2. The indoor heat exchanger 11 and the cross flow fan 12 mentioned above are accommodated in the 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 rear upper part of the cross flow fan 12. The indoor heat exchanger 11 passes the air sucked in from the suction port 142 by the drive of the cross flow fan 12 to the cross flow fan 12 side, and performs heat exchange with the refrigerant passing through the inside of the heat transfer pipe. do.

Further, 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 equipped with a drain hose (not shown) for discharging the received water droplets to the outside. The drain pan 141 is configured to receive such water droplets and to drain the water droplets by the drain hose.

In the upper part of the casing 14, the suction port 142 which consists of a some slit-shaped opening is provided. In the lower part of the casing 14, the ejection opening 143 which consists of an opening long in the longitudinal direction of the indoor unit 2 is provided. In addition, the blowout port 143 is provided with a horizontal flap (upper and lower flap) 144 for determining a blowout direction of the air blown into the room by the cross flow fan 12. This horizontal flap 144 is rotatably provided about the axis 145 parallel to the longitudinal direction of the indoor unit 2, and can be rotated. The horizontal flap 144 can be rotated by the flap motor 146 (refer FIG. 7) mentioned later, and can determine the blow-out direction of air. As shown in FIG. 4, when the edge part 144a of the horizontal flap 144 faces a substantially horizontal direction, the air after roughening blows out in a substantially horizontal direction. In addition, as shown in FIG. 5, when the edge part 144a of the horizontal flap 144 faces a substantially vertical downward direction, the air after roughening blows out in a substantially vertical downward direction. Furthermore, as shown in FIG. 6, the edge part 144a of the horizontal flap 144 is in contact with the edge part of the casing 14 at the time of the operation stop of the air conditioner 1. As shown in FIG. In this case, the horizontal flap 144 almost completely covers the outlet port 143.

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

<Control part>

The air conditioner 1 is further provided with a control unit 60.

As shown in FIG. 7, the control unit 60 includes a compressor 21, a four-way switching valve 22, a pressure reducer 25, a ROM 41, a RAM 42, a fan motor 13, and a flap motor. 146, the temperature sensor 43, and the infrared sensor 44 are connected. In addition, the controller 60 communicates with the remote controller 40 and limits the time of the powerful operation by the timer 45 operating 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.

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

The set amount of air is the amount of driving air to determine the amount of air blown out from the air outlet 143, and specifically, is one of "quiet", "breeze", "weak", "weak", "weak" and "strong" . "Quiet" shows the driving wind volume with the smallest air volume, and "strong wind" shows the driving wind volume with the largest wind volume. The control unit 60 selects any one of the set air flows based on a signal from the remote controller 40 to be described later, and stores the selected set air flows in the RAM 42. And the control part 60 rotates the fan motor 13 so that the air after mixing the quantity according to the selected set air volume may be blown indoors.

The remote control unit 40 is an operation device for transmitting the instruction of the occupant to the air conditioner 1 and for operating the air conditioner 1 according to the requirements of the occupant. The occupant can use the remote controller 40 to set room temperature, turn ON / OFF the swing function of the horizontal flap 144, select the swing mode, input an instruction for powerful operation, and the like.

Here, the powerful operation is to temporarily increase the rotation speed of the cross flow fan 12, the operating frequency of the compressor 21, or the like by an instruction input from the user, and can temporarily improve the air conditioning processing capability. In addition, this powerful operation is explained later.

This instruction is transmitted from the remote control unit 40 to the control unit 60 and used for control of each configuration. In addition, such an instruction is transmitted from the control unit 60 to the RAM 42 together with the person detection result (information on the direction in which the person is located) by the infrared sensor 44, and stored in the RAM 42.

Further, by using the remote controller 40, the target temperature T by the operation of the air conditioner 1 can be set. This target temperature T is transmitted to the control part 60 from the remote control 40, and is used for control of each structure. The target temperature T is sent from the control unit 60 to the RAM 42 and stored in the RAM 42. For example, when room temperature falls below predetermined temperature t1 or more than target temperature T at the time of cooling operation, the control part 60 operates the compressor 21 in order to suppress the energy consumption of the air conditioner 1. To stop. On the other hand, when the room temperature exceeds the target temperature T by the predetermined temperature t2 or more due to the stop of the compressor 21, the control unit 60 drives the compressor 21 again.

The temperature sensor 43 is installed in the indoor unit 2 and measures the room 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 person detection sensor that detects a person in the room. The infrared sensor 44 transmits information on the direction in which the person is detected to the control unit 60. In addition, the detection of a person using the infrared sensor 44 may be performed at all times, or may be performed every predetermined time.

<Powerful operation by this air conditioner>

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

For example, when 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 is a cross flow fan (to improve the air conditioning processing capability). The fan motor 13 is controlled to increase the rotational speed of 12, and the operating frequency of the compressor 21 is controlled.

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

Thus, even if the horizontal flap 144 is directed in any direction at the time of driving before the instruction input of the powerful driving, the direction of the horizontal flap 144 is always in the direction of the human being when the instruction of the powerful driving is input. Is controlled to change. Therefore, the user can feel the powerful feeling by the powerful driving by receiving the air-conditioned air directly by the instruction input of the powerful driving.

Such powerful operation is similarly carried out at the time of heating operation.

In addition, powerful operation temporarily raises the air conditioning processing capability of the air conditioner 1, and the time for performing powerful operation is limited by the timer 45. FIG. This timer 45 starts measuring time after the control part 60 receives the powerful driving instruction input from a user, and transmits a signal to the control part 60 when a predetermined time approaches. Upon receiving a 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, and terminates the powerful operation. Returns to the operating state of.

In addition, in the air conditioner 1 of this embodiment, the timer 45 sets a time to prevent condensation in the vicinity of the blower outlet 143 even when air blows directly to the blower outlet 143 at the time of cooling powerful operation. It is input as time.

As a result, even if the horizontal flap 144 is directed in any direction during the cooling powerful operation, it is possible to reliably prevent the problem that dew condensation occurs near the ejection opening 143 by placing a time limit.

<Characteristic of this air conditioner>

(One)

The air conditioner 1 of the first embodiment temporarily raises the rotational speed of the crossflow fan 12, the operating frequency of the compressor 21, and the like, when an instruction input for performing a powerful operation is received from the remote controller 40. In addition to improving the processing capacity, the wind direction is also controlled.

Even in a conventional air conditioner, when an instruction input such as such that the processing capacity is temporarily increased, raising the rotation speed of the fan, the operating frequency of the compressor, and the like has been performed. However, since it was not controlled to the blowing direction of the air supplied to the room at this time, the wind direction was determined by the direction of the horizontal flap immediately before the instruction input of a powerful operation.

Therefore, in the air conditioner 1 of this embodiment, the direction of the horizontal flap 144 is controlled also in the case of the so-called powerful operation | movement which temporarily raises a processing capability, and desires the air-conditioned air in the state in which the driving capability rose. Can be blown in the direction.

In particular, in the air conditioner 1 of this embodiment, the direction of the horizontal flap 144 is controlled to blow air | air-conditioned air toward the direction of the person in a room.

Thereby, when the user sets the powerful driving, the air-conditioned air blows toward the user, so that the user can feel the powerful feeling at the time of the powerful driving.

(2)

The air conditioner 1 of the first embodiment detects the direction in which people are indoors using the infrared sensor 44.

Thereby, even if there is a person in any position of the room, the direction of the horizontal flap 144 can be adjusted so that a wind may directly contact a person.

(3)

The air conditioner 1 of the first embodiment fixes the direction of the horizontal flap 144 when the instruction input of the powerful operation is input, and blows the air-conditioned air in the direction of the person.

As a result, the user in the room can be surely felt at the time of powerful driving.

(4)

The air conditioner 1 of the first embodiment limits the time for performing the powerful operation using the timer 45.

This makes it possible to control the powerful operation by temporarily raising the air conditioning processing capacity.

(5)

In the air conditioner 1 of the first embodiment, the set time of the timer 45 is set to a time such that condensation does not occur in the vicinity of the outlet 143 of the indoor unit 2.

Usually, in the powerful operation at the time of cooling, when the horizontal flap 144 is directed in the direction of a person, the air-conditioned air may contact the vicinity of a blower outlet. In such a case, if it blows cold air for a long time as it is, there is a possibility that it will condensate in the vicinity of a blowout port.

Therefore, in the air conditioner 1 of this embodiment, by limiting the time that the horizontal flap 144 goes to the direction, it can reliably prevent dew condensation in the vicinity of the blower outlet 143. FIG.

(6)

The air conditioner 1 of 1st Example uses the horizontal flap 144 to control the blowing direction of the air supplied to the room.

Thereby, compared with the case where the direction of a vertical flap is controlled, it controls by using the horizontal flap 144 which adjusts the wind direction of an up-down direction, and can blow air easily toward a human direction. .

<Modified Example of First Embodiment>

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

(A)

In the first embodiment, an infrared sensor 44 is used to sense a direction in which a person is present and an example of blowing air-conditioned air at the time of powerful driving in the direction has been described. However, the present invention is not limited to this. For example, without using a sensor, the air-conditioned air may be blown toward a specific range assumed for the place where a person is.

In addition, the sensor is not limited to an infrared sensor as long as it can detect a place where a person is, and other sensors 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 the direction of a person during powerful driving. However, the present invention is not limited to this. For example, as shown in Fig. 9A, in the case of normal cooling operation, when the horizontal flap 144 swings between the horizontal direction and the downward direction several times in the horizontal direction, At the time of powerful driving, as shown in FIG. 9 (b), the swing flap 144 may be swinged by extending the swing range to include the direction in which a person is present. Also in this case, since the user can directly feel the air blown out at the time of powerful driving, the user can feel the powerful feeling similarly to the case where the horizontal flap 144 is fixed to face the human direction.

(C)

In the first embodiment, an example is described in which the direction of the horizontal flap 144 is controlled to blow air-conditioned air into the room during the powerful driving in the direction of the human in the vertical direction. However, the present invention is not limited to this. For example, the wind direction may be controlled in the horizontal direction using the vertical flap, and the wind direction may be controlled using both the vertical flap and the horizontal flap 144.

(D)

In the first embodiment, an example of controlling the direction of the horizontal flap 144 so as to blow air-conditioned air in a direction where a person is present, when an instruction is inputted to perform powerful operation regardless of the time of cooling and heating. It explained. 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 toward the direction in which a person is present only when there is an instruction input of the powerful operation at the time of cooling.

Thereby, a user can feel the cooling feeling in the powerful driving at the time of cooling, and can feel the powerful feeling at the time of powerful driving.

(E)

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

[Example 2]

The air conditioner according to the second embodiment controls the flap motor 146 so that the control unit 60 blows out the air heat-treated (air conditioner) by the indoor heat exchanger 11 in the direction of no human, and thus the horizontal flap. It differs from the air conditioner concerning a 1st Example by adjusting the direction of 144. FIG. Therefore, here, only the operation of the air conditioner in powerful operation is mentioned.

<Powerful operation by air conditioner>

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

For example, when 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 is a cross flow fan (to improve the air conditioning processing capability). The fan motor 13 is controlled to increase the rotational speed of 12, and the operating frequency of the compressor 21 is controlled.

In the air conditioner 1 of the second embodiment, in particular, when a command input of powerful operation is received, the control unit 60 controls the direction of the horizontal flap 144 in addition to the control described in the first embodiment. For example, at the time of cooling operation, as shown in FIG. 10 (a), it is assumed that the air conditioned air is blown into the room S slightly downward in the substantially horizontal direction. Here, if there is a command input of the powerful operation, according to the detection result from the infrared sensor 44, as shown in FIG. 10 (b), heat exchange processing (air) is performed by the indoor heat exchanger 11 in a direction without a person. The flap motor 146 is controlled to blow out the adjusted air to adjust the direction of the horizontal flap 144.

As a result, even when the horizontal flap 144 is directed in any direction at the time of driving before the instruction input of the powerful driving, the direction of the horizontal flap 144 is always in the direction of no human when the instruction of the powerful driving is input. Is controlled to change. Therefore, even if the occupant enters a powerful driving instruction, the occupant can comfortably spend indoors without feeling the excessive cooling caused by the direct wind.

Such powerful operation is similarly carried out at the time of heating operation.

In addition, powerful operation temporarily raises the air conditioning processing capability of the air conditioner 1, and the time for performing powerful operation is limited by the timer 45. FIG. This timer 45 starts measuring time after the control part 60 receives the powerful driving instruction input from a user, and transmits a signal to the control part 60 when a predetermined time approaches. Upon receiving a signal from the timer 45, the control unit 60 controls the fan motor 13, the compressor 21, and the flap motor 146 so as to return to the original normal operation state, and terminates the powerful operation. Return to normal operation.

<Characteristic of the air conditioner>

(One)

The air conditioner 1 of the second embodiment temporarily raises the rotational speed of the crossflow fan 12, the operating frequency of the compressor 21, and the like, when an instruction input for powerful operation is performed from the remote controller 40. In addition to improving the coordination processing capability, the wind direction is controlled.

Even in a conventional air conditioner, when an instruction input such as such that the processing capacity is temporarily increased, raising the rotation speed of the fan, the operating frequency of the compressor, and the like has been performed. However, since the air was not controlled to the blowing direction of the air supplied to the room at this time, the wind direction was determined by the direction of the horizontal flap 144 immediately before the instruction input of the powerful operation. As a result, after the start of powerful driving, the horizontal flap 144 is directed toward the person, and the air-conditioned air directly touches the person, which may cause discomfort to the person.

Therefore, in the air conditioner 1 of this embodiment, the direction of the horizontal flap 144 is controlled also in the case of the so-called powerful operation | movement which temporarily raises a processing capability, and desires the air-conditioned air in the state in which the driving capability rose. Can be blown in the 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, avoiding the direction in which a person is present.

As a result, when the user sets the powerful driving, the air conditioned air is blown toward a direction other than the direction of the person, for example, near the ceiling. Thus, for example, even when powerful driving is provided at the time of cooling, direct cooling air can be prevented from directly contacting a person, and thus powerful driving can be performed without causing discomfort due to excessive cooling.

(2)

The air conditioner 1 of the second embodiment uses the infrared sensor 44 to detect the direction of a person in the room.

Thereby, even if there is a person in any position of the room, the direction of the horizontal flap 144 can be adjusted so that a wind may not directly contact a person.

(3)

The air conditioner 1 of the second embodiment fixes the direction of the horizontal flap 144 when the instruction input of the powerful operation is input, and blows the air-conditioned air in the direction without a person.

As a result, for example, it is possible to prevent the user in the room from being uncomfortable due to excessive cooling feeling caused by direct cold wind upon cooling.

(4)

The air conditioner 1 of the second embodiment limits the time for performing the powerful operation by using the timer 45 operating inside the program.

This makes it possible to control the powerful operation by temporarily raising the air conditioning processing capacity.

(5)

The air conditioner 1 of 2nd Example uses the horizontal flap 144 to control the blowing direction of the air supplied to the room.

Thereby, compared with the case where the direction of a vertical flap is controlled, it controls by using the horizontal flap 144 which adjusts the up-and-down wind direction, and it can blow air toward a direction without a person easily. .

<Modification Example of Second Embodiment>

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

(A)

In the second embodiment, an example has been described in which the direction of the horizontal flap 144 is fixed in a direction without a person during powerful driving. However, the present invention is not limited to this. For example, as shown in Fig. 11A, in the case of the cooling operation, when the horizontal flap 144 is swinging in the downward direction for several times from the horizontal direction, the power flap is changed during the operation. As shown to 11 (b), you may swing the horizontal flap 144 in the range which does not include the direction where a person is present. Also in this case, since the air blown out at the time of powerful driving does not directly contact, like the case where the horizontal flap 144 is fixed to a direction without a person, the user can perform powerful driving without discomfort. .

(B)

In the second embodiment, an example is described in which the direction of the horizontal flap 144 is controlled to blow air-conditioned air into the room during the powerful driving in the direction of no human in the vertical direction. However, the present invention is not limited to this. For example, the wind direction may be controlled in the left and right directions by using the vertical flap or both the horizontal flap 144 and the vertical flap.

(C)

In the second embodiment, an example in which the direction of the horizontal flap 144 is controlled to blow out the air-conditioned air in a direction without a person when an instruction is inputted to perform a powerful operation regardless of the time of cooling and heating. It explained. 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 toward the direction where there is no person only when there is an instruction input of the powerful operation at the time of cooling.

Since the present invention has the effect of being able to control the blowing direction of air-conditioned air at the time of powerful operation, the present invention can be applied to an air conditioner capable of performing a powerful operation at the time of a cooling operation and a heating operation.
