Description

  The present invention relates to an air conditioner capable of performing a powerful operation that temporarily increases the rotational speed of a fan, the operating frequency of a compressor, and the like to improve the air conditioning processing capability, and a control method thereof.

2. Description of the Related Art Conventionally, there is known an air conditioner that is installed in a house / building or the like and improves indoor comfort by blowing conditioned air into the room. Such an air conditioner keeps the indoor temperature at a comfortable temperature for the occupant by blowing cool air or warm air into the room, thereby improving the comfort of the room.
The air conditioner includes an air conditioning indoor unit installed in a room that performs air conditioning and an air conditioning outdoor unit installed outdoors. The air conditioning indoor unit and the air conditioning outdoor unit are connected by a refrigerant pipe, and air conditioning is performed by performing heat exchange between the refrigerant flowing through the refrigerant pipe and the room air.

Among such air conditioners, in particular, during cooling operation or heating operation, etc., in order to improve the air conditioning processing capacity by temporarily increasing the operating frequency of the compressor, the fan rotation speed, etc. by instruction input from the user, Some perform so-called powerful operation. By inputting a powerful operation instruction using a remote controller or the like, it is possible to temporarily increase, for example, the air conditioning capability of air conditioning that is currently operating.
Japanese Unexamined Patent Publication No. 7-103551 (published on April 18, 1995)

However, the conventional air conditioner has the following problems.
That is, in the conventional air conditioner, when an instruction to perform a powerful operation is input, as described above, the compressor is controlled to increase the operating frequency of the compressor, the rotational speed of the fan, and the like, and the air conditioning processing capability is increased. However, the direction of the air-conditioned air at this time is not controlled at all, and the direction of the air direction adjusting plate when the powerful operation instruction is input causes the direction of the air to be blown out. It was decided.

For this reason, for example, when a powerful operation instruction is input during cooling, air conditioned air is supplied into the room with increased processing capacity, but this air may directly hit a person, For example, during cooling and powerful operation, there is a possibility of giving uncomfortable feelings such as excessive cooling to the residents.
The subject of this invention is providing the air conditioner which can control the blowing direction of the air by which air conditioning was carried out at the time of powerful operation, and its control method.

The air conditioner according to claim 1 temporarily increases an air conditioning mechanism that performs an air conditioning process on indoor air, a wind direction adjusting plate that adjusts an air blowing direction, and a processing capacity of the air conditioning mechanism. And a control unit capable of performing powerful operation. And a control part will switch to 1st control, if the instruction | indication of a powerful driving | operation is made. In the first control, the direction of the wind direction adjusting plate is controlled so that the air blows out in the direction where no one is present.

Here, when a command is input for a powerful operation, the control unit not only increases the processing capacity of the air-conditioning mechanism including a compressor and a fan, but also blows out the air-conditioned air supplied to the room. Also comes to control.
In a conventional air conditioner, the processing capability of the air conditioning mechanism is only temporarily improved during a powerful operation, and the air blowing direction at that time is not a target of control. For this reason, the direction of the wind direction adjusting plate immediately before the powerful operation instruction is input determines the direction of the wind direction adjusting plate during the powerful operation. Therefore, for example, even when a powerful operation is executed during the same cooling, the direction of the wind direction adjusting plate may be different depending on the operation state immediately before that. As a result, there is a problem that the occupant feels uncomfortable feeling due to excessive cooling sensation because the air conditioned cold air directly hits the occupant during the cooling powerful operation.

Therefore, in the air conditioner of the present invention, the following effects can be obtained by controlling the direction of the wind direction adjusting plate even during powerful operation.
That is, in the air conditioner of the present invention, when a powerful operation instruction is input, the direction of the wind direction adjusting plate is controlled so as to blow out air that has been air conditioned in a direction where no one is present. Thereby, it is possible to prevent the occupant from being given discomfort due to excessive cooling feeling during cooling operation, discomfort due to direct contact with warm air during heating, and the like.

An air conditioner according to a second aspect is the air conditioner according to the first aspect, further comprising a storage unit. The storage unit stores a setting value of the direction of the wind direction adjusting plate during the powerful operation. In the first control, the direction of the wind direction adjusting plate is controlled according to the set value. This set value is a value that reflects the direction of the wind direction adjusting plate such that air blows out in a range other than the specific range estimated as the location of the person.

Here, in the first control, the direction of the wind direction adjusting plate is controlled according to the set value of the direction of the wind direction adjusting plate during the powerful operation. For this reason, it is not necessary to use an infrared sensor or the like for human detection.
The air conditioner according to claim 3 is the air conditioner according to claim 1, further comprising a sensor for sensing a human. In the first control, the direction of the wind direction adjusting plate is controlled based on information from the sensor.

Here, a sensor for detecting a person in the room is further provided. This makes it possible to adjust the wind direction so that it does not hit a person reliably during powerful operation.
An air conditioner according to a fourth aspect is the air conditioner according to any one of the first to third aspects , wherein in the first control, a wind direction adjusting plate is blown out so that air is blown in a direction in which no one is present. The orientation of is fixed,
Here, when a powerful operation instruction is input, the direction of the wind direction adjusting plate is fixed in a direction where no one is present. Thereby, for example, it is possible to reliably prevent a person from feeling uncomfortable due to excessive cooling during cooling operation.

The air conditioner according to claim 5 is the air conditioner according to any one of claims 1 to 3 , wherein in the first control, the wind direction adjusting plate swings so as not to include a direction in which a person is present. To be
Here, even when powerful operation is set while the wind direction adjusting plate is swinging, the range is changed to a swing range in which no wind hits a person. Thus, even when air that is directly conditioned to the person is blown before the powerful operation, it is possible to reliably prevent the air from being directly blown to the person during the powerful operation.

An air conditioner according to a sixth aspect of the present invention is the air conditioner according to any one of the first to fifth aspects, further comprising a timer for limiting a time for performing a powerful operation.
Here, a timer for limiting the time for performing powerful operation is further provided. Thereby, the time which performs a powerful driving | running can be restrict | limited and air conditioning processing capability, such as air conditioning, can be improved temporarily.

An air conditioner according to a seventh aspect is the air conditioner according to any one of the first to sixth aspects, wherein the wind direction adjusting plate is a vertical flap.
Here, it is determined whether or not to hit the person by controlling the direction of the upper and lower flaps of the wind direction adjusting plate. For this reason, it is possible to easily adjust the wind direction adjusting plate in a direction that does not hit a person simply by swinging the blowing direction up and down.

An air conditioner according to an eighth aspect is the air conditioner according to any one of the first to seventh aspects, wherein the wind direction adjusting plate is an upper and lower flap and a vertical flap.
The air conditioner according to claim 9 is the air conditioner according to any one of claims 1 to 8 , wherein the control of the direction of the wind direction adjusting plate is set to a powerful operation during a cooling operation. Done in case.

Here, the control of the direction of the wind direction adjusting plate when executing the powerful operation is performed only during the cooling operation. That is, when performing the cooling and powerful operation, control is performed so that the cold air does not directly hit a person. Thereby, it can prevent giving the person the discomfort by an excessive cooling sensation.
The method of controlling an air conditioner according to claim 10 includes an air conditioning mechanism that performs an air conditioning process on indoor air, and a wind direction adjusting plate that adjusts a blowing direction of the air, and a processing capacity of the air conditioning mechanism. It is a control method of the air conditioner which can perform the powerful driving | operation which raises temporarily. When a powerful operation instruction is input , the control is switched to the first control . In the first control, the direction of the wind direction adjusting plate is controlled so that the air blows out in the direction where no one is present.

Here, when a command is input for a powerful operation, the control unit not only increases the processing capacity of the air-conditioning mechanism including a compressor and a fan, but also blows out the air-conditioned air supplied to the room. Also comes to control.
In the conventional air conditioner control method, the processing capacity of the air conditioning mechanism is only temporarily improved during a powerful operation, and the air blowing direction at that time is not a target of control. For this reason, the direction of the wind direction adjusting plate immediately before the powerful operation instruction is input determines the direction of the wind direction adjusting plate during the powerful operation. Therefore, for example, even when a powerful operation is executed during the same cooling, the direction of the wind direction adjusting plate may be different depending on the operation state immediately before that. As a result, at the time of cooling powerful operation, there is a problem that the occupant feels uncomfortable feeling due to excessive cooling sensation because the air conditioned cold air directly hits the occupant.

Therefore, in the air conditioner control method of the present invention, the following effects can be obtained by controlling the direction of the wind direction adjusting plate even during a powerful operation.
That is, in the air conditioner control method of the present invention, when a powerful operation instruction is input, the direction of the air direction adjusting plate is controlled so that air conditioned air is blown out in a direction where no one is present. .

The outdoor heat exchanger 24 is connected to the four-way switching valve 22. The decompressor 25 is an electric expansion valve connected to the outdoor heat exchanger 24. The decompressor 25 is connected to the pipe 31 via the filter 26 and the liquid closing valve 27, and is connected to one end of the indoor heat exchanger 11 via the pipe 31. Further, 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 this pipe 32. The pipes 31 and 32 correspond to the refrigerant pipe 6 in FIG.

  A sectional view of the indoor unit 2 is shown in FIG. The indoor heat exchanger 11 and the cross flow fan 12 described 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, upper and rear upper portions of the cross flow fan 12. The indoor heat exchanger 11 allows the air sucked from the suction port 142 by the drive of the cross flow fan 12 to pass to the cross flow fan 12 side, and exchanges heat with the refrigerant passing through the heat transfer tube.

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

  A suction port 142 made up of a plurality of slit-like openings is provided in the upper part of the casing 14. At the lower part of the casing 14, a blow-out port 143 having an opening that is long in the longitudinal direction of the indoor unit 2 is provided. The outlet 143 is provided with a horizontal flap (upper and lower flaps) 144 for determining the direction in which the air blown into the room by the cross flow fan 12 is blown. The horizontal flap 144 is provided so as to be rotatable about a shaft 145 parallel to the longitudinal direction of the indoor unit 2. The horizontal flap 144 can determine the air blowing direction by being rotated by a flap motor 146 (see FIG. 7) described later. As shown in FIG. 4, when the end portion 144a of the horizontal flap 144 is directed in the substantially horizontal direction, the conditioned air is blown out in the substantially horizontal direction. Further, as shown in FIG. 5, when the end portion 144a of the horizontal flap 144 is directed substantially vertically downward, the conditioned air is blown substantially vertically downward. Further, as shown in FIG. 6, when the operation of the air conditioner 1 is stopped, the end portion 144 a of the horizontal flap 144 is in contact with the end portion of the casing 14. In this case, the horizontal flap 144 almost completely covers the outlet 143.

In the outdoor air conditioning unit 5, a propeller fan 29 for discharging the air after heat exchange in the outdoor heat exchanger 24 to the outside is provided. The propeller fan 29 is rotationally driven by a propeller fan motor 30.
<Control unit>
The air conditioner 1 is further provided with 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 decompressor 25, the ROM 41, the RAM 42, the fan motor 13, the flap motor 146, the temperature sensor 43, and the infrared sensor 44. . Further, the control unit 60 communicates with the remote controller 40 and limits the time of powerful operation by a timer 45 that works inside the program. Further, the control unit 60 controls the compressor 21, the four-way switching valve 22, the decompressor 25, the fan motor 13 and the flap motor 146.

The ROM 41 stores control programs and various parameters. The ROM 41 further stores the set air volume at various settings, the position of the horizontal flap 144 at the time of powerful operation setting, the swing range, and the like.
The set air volume is an operating air volume that determines the air volume of air blown from the air outlet 143. Specifically, “Shizuka”, “Slight wind”, “Weak”, “Weak wind”, “Weak strong”, “ One of the "strong winds". “SHIZUKA” indicates the driving air volume with the smallest air volume, and “strong wind” indicates the operating air volume with the largest air volume. The control unit 60 selects one of the set air volumes based on a signal from the remote controller 40 described later, and stores the selected set air volume in the RAM 42. And the control part 60 rotates the fan motor 13 so that the air after conditioning of the quantity according to the selected setting air volume may be ventilated indoors.

The remote controller 40 is an operation device for transmitting an instruction of a room occupant to the air conditioner 1 and operating the air conditioner 1 according to the demand of the room occupant. The resident can use the remote control 40 to set the room temperature, turn on / off the swing function of the horizontal flap 144, select the swing mode, input a powerful operation instruction, and the like.
Here, the powerful operation is to temporarily improve the air conditioning processing capability by temporarily increasing the rotational speed of the cross flow fan 12, the operation frequency of the compressor 21 or the like by an instruction input from the user. It can be done. This powerful operation will be described in detail later.

These instructions are transmitted from the remote control 40 to the control unit 60 and used for control of each component. These instructions are transmitted from the control unit 60 to the RAM 42 and stored in the RAM 42 together with the result of human detection by the infrared sensor 44 (information on the direction in which the person is present).
Furthermore, the target temperature T by the operation of 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 used for control of 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 (t1) 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 a human sensor that is provided near the surface of the indoor unit 2 and detects a person in the room. The infrared sensor 44 transmits information about the direction in which the detected person is present to the control unit 60. It should be noted that human sensing using the infrared sensor 44 may be performed constantly or may be performed at predetermined time intervals.

<Powerful operation with 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 increases the rotational speed of the cross flow fan 12 in order to improve the air conditioning processing capability. In addition to controlling the fan motor 13, the operation frequency of the compressor 21 is controlled.

  In the air conditioner 1 of the present embodiment, in particular, when receiving an instruction input for powerful operation, the control unit 60 controls the direction of the horizontal flap 144 in addition to the above control. For example, it is assumed that air that has been air-conditioned slightly downward from a substantially horizontal direction is blown out into the room S as shown in FIG. Here, if there is an instruction input for powerful operation, according to the detection result from the infrared sensor 44, as shown in FIG. The flap motor 146 is controlled to blow out the harmonized air, and the direction of the horizontal flap 144 is adjusted.

  As a result, regardless of the direction in which the horizontal flap 144 is directed during the operation before the powerful operation instruction is input, the direction of the horizontal flap 144 is always in the direction in which no one is present when the powerful operation instruction is input. Is controlled to change. Therefore, the occupant can spend comfortably in the room without feeling an excessive cooling feeling due to the direct wind at the time of cooling even when the instruction for powerful driving is input.

Such a powerful operation is performed in the same way during the heating operation.
The powerful operation temporarily enhances the air conditioning processing capability of the air conditioner 1, and the time for performing the powerful operation is limited by the timer 45. The timer 45 starts measuring time after the control unit 60 receives a powerful driving instruction input from the user, and transmits 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 flap motor 146 so as to return to the original normal operation state, ends the powerful operation, and returns to the normal operation state. .
[Characteristics of air conditioner]
(1)
The air conditioner 1 according to the present embodiment temporarily increases the rotational speed of the cross flow fan 12, the operating frequency of the compressor 21, and the like when the instruction input for performing the powerful operation is received from the remote controller 40, and the air conditioning processing capability. In addition, the wind direction is controlled.

  Even in a conventional air conditioner, when such an instruction is input to temporarily increase the processing capacity, the rotational speed of the fan, the operating frequency of the compressor, and the like have been increased. However, at this time, the direction of blowing the air supplied to the room was not controlled, so the wind direction was determined by the direction of the horizontal flap 144 immediately before the powerful operation instruction was input. As a result, after the start of powerful operation, the horizontal flap 144 is directed in the direction in which the person is present, and the air-conditioned air may directly hit the person and give the person an uncomfortable feeling.

Therefore, in the air conditioner 1 of the present embodiment, the air that has been conditioned in the state in which the driving ability is increased is controlled by controlling the direction of the horizontal flap 144 even during so-called powerful operation, which temporarily increases the processing ability. It can be blown out in a desired direction.
In particular, in the air conditioner 1 of the present embodiment, the orientation of the horizontal flap 144 is controlled so as to blow out air that has been conditioned while avoiding the direction in which a person is present.

  As a result, when powerful operation is set by the user, air that is air-conditioned is blown out in a direction other than the direction in which the person is present, for example, in the vicinity of the ceiling or the like. Therefore, for example, even when a powerful operation is installed at the time of cooling, it is possible to prevent direct cold air from directly hitting a person, so that it is possible to perform a powerful operation without causing discomfort due to excessive cooling.

(2)
The air conditioner 1 of the present embodiment senses the direction in which a person is present in the room using the infrared sensor 44.
As a result, the horizontal flap 144 can be adjusted so that the wind does not directly hit the person regardless of where the person is in the room.

(3)
In the air conditioner 1 according to the present embodiment, when a powerful operation instruction is input, the direction of the horizontal flap 144 is fixed, and air that has been air conditioned is blown out in a direction where no one is present.
Thereby, for example, it is possible to prevent an uncomfortable feeling from being given to a user in a room due to an excessive cooling feeling caused by a direct cold wind during cooling.

(4)
The air conditioner 1 of the present embodiment limits the time for performing a powerful operation using a timer 45 that operates inside the program.
This makes it possible to control the powerful operation as temporarily increasing the air conditioning processing capacity.

(5)
The air conditioner 1 of this embodiment controls the blowing direction of the air supplied indoors using the horizontal flap 144. FIG.
Thereby, compared with the case where the direction of the vertical flap is controlled, the air can be easily blown out in the direction where there is no person by performing the control using the horizontal flap 144 that adjusts the vertical wind direction. .
[Other Embodiments]
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 invention.

(A)
In the above-described embodiment, the direction in which a person is present is sensed using the infrared sensor 44, and the air-conditioned air during powerful operation is blown out in a direction other than that direction. However, the present invention is not limited to this. For example, air conditioned air may be blown toward a range other than a specific range that is assumed to be a person's place without using a sensor.

In addition, the sensor is not limited to the infrared sensor as long as it can sense a person's whereabouts, and other sensors may be used.
(B)
In the above-described embodiment, the example in which the direction of the horizontal flap 144 is fixed in a direction where no one is present during the powerful operation has been described. However, the present invention is not limited to this. For example, as shown in FIG. 9 (a), when the horizontal flap 144 swings between the horizontal direction and the downward direction by several degrees during the cooling operation, the state shown in FIG. As shown, the horizontal flap 144 may be swung within a range that does not include the direction in which the person is present. Even in this case, since the user does not directly hit the air blown during the powerful operation, the user can perform the powerful operation without giving unpleasant feeling similarly to the case where the horizontal flap 144 is fixed so as to face the direction where there is no person. Can be executed.

(C)
In the above-described embodiment, an example has been described in which the direction of the horizontal flap 144 is controlled to blow out air that has been air-conditioned during powerful operation in the vertical direction in the absence of people. However, the present invention is not limited to this. For example, the wind direction may be controlled in the left-right direction using a vertical flap or both a horizontal flap 144 and a vertical flap.

(D)
In the above embodiment, the direction of the horizontal flap 144 is controlled so as to blow out air conditioned in a direction that is not present when an instruction is input to perform a powerful operation regardless of whether it is cooling or heating. Explained with an example. 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 air conditioned in the direction where there is no person is blown out only when a command for powerful operation is input during cooling.

  The present invention can be applied to an air conditioner capable of performing a powerful operation during a cooling operation and a heating operation because the air blowing direction in which air conditioning is performed can be controlled during the powerful operation.
