Abstract

(assignment)

Effectively cooperate with the air conditioning room.

(Solution)

The indoor unit 12 normally blows air-conditioning air from the outlet toward the main area where the main remote controller 120 is placed. In addition, the sub remote controller 140 transmits a signal for designating a sub area in the air-conditioning room. When the indoor unit receives a signal from the sub-remote controller, the indoor unit emits blow-out wind while swinging the left and right flaps 52 so that blow-out wind is deflected in the direction specified by the sub-remote controller. Thereby, the sub area designated by the sub remote controller is air-conditioned so as to be in a desired air condition state.

Description

Air Conditioner {AIRCONDITIONER}

The present invention relates to an air conditioner for air conditioning in a room to be installed in which an indoor unit is installed.

An air conditioner (hereinafter referred to as an “air conditioner”) is configured to blow air temperature controlled into the air conditioning chamber by passing through a heat exchanger of an indoor unit (indoor unit) installed in the air conditioning chamber, to achieve air conditioning in the air conditioning chamber. It is. The installation position of the indoor unit of the air conditioner is preferably a position that can emit air conditioning air toward the whole of the room. That is, by blowing out the temperature-controlled air from the indoor unit toward the entire area of the room, the entire area of the room can be uniformly desired.

In recent years, the air-conditioning room to which the indoor unit is set has become wider, and the shape can be diversified, such as being formed in an L shape. In addition, the installation position of the indoor unit needs to avoid windows, doors, girders and the like, and is often restricted. For this reason, an air conditioner with high air conditioning capability is required to uniformly air-condition the entire large room with one indoor unit.

However, from the energy saving point of view, it is not desirable to make the entire room even. In other words, even if the room is large, the space with a lot of people is often limited, and coordination of the entire room is necessary to spread the temperature-controlled air even in a space without people, and to increase the use of the air conditioning. Will be created.

SUMMARY OF THE INVENTION The present invention has been made in view of the above fact, and an object of the present invention is to propose an air conditioner that can efficiently perform air conditioning without impairing the comfort in the air-conditioned room by air conditioning a desired position in a large room.

An air conditioner according to claim 1 is an air conditioner in which an air conditioner is air-conditioned by blowing out temperature-controlled air from a spout of an indoor unit in an air-conditioned chamber provided with an indoor unit, and is placed in an area having a normal person in the air-conditioned chamber. The main remote control unit for setting the operation state of the indoor unit, and is installed separately from the main remote control, and installed and disposed at a predetermined position in an area different from the area where the main remote control is placed in the air conditioning room, Human detection means for detecting the presence of a person, selection means for selecting a relative position of the disposed area with respect to the indoor unit from a preset relative position with respect to the indoor unit, and a detection result by the human detection means A signal indicating the signal and the relative position selected by the selection means as an output signal A sub-remote controller having an output means for outputting, and a temperature-controlled air blown out from the jet port toward at least one of a first region in which the sub-remote controller is installed and a second region in which the main remote control is provided; Deflecting means for selectively deflecting, operating said deflecting means according to said output signal, and said first region if said person is detected by said person detecting means, and said second area if no person is detected; And deflecting the temperature-controlled air, respectively.

According to the present invention, an area in which a main remote control for setting an operating state of an indoor unit is placed in an area where an ordinary person is located in an air-conditioned room, and a sub-remote control unit provided separately from the main remote control is placed in the air-conditioned room. It is provided and disposed at a predetermined position in a different area from the one provided. Further, in the sub-remote controller, presence or absence of a person in the area to be arranged is detected by the person detecting means, the relative position with respect to the indoor unit of the arranged area is selected from the selection means from the relative position with respect to the indoor unit set in advance, and the person detecting means The signal indicating the detection result by and the signal indicating the relative position selected by the selecting means are output by the transmitting means. Moreover, the temperature-controlled air blown out from the blower outlet is selectively deflected by at least one of the 1st area | region in which the said sub remote controller is installed in the air-conditioned chamber, and the 2nd area | region in which the said main remote control machine is put by deflecting means. In addition, the deflection means is operated in accordance with the output signal to deflect temperature controlled air in the first area when the person detection means detects a person, and in the second area when no person is detected.

While the main remote control is placed in an area where a person is normally located in the air-conditioning room, the sub remote control can be arranged at a position (place) where a human time is shorter than the place where the main remote control is placed.

In addition, although the blowing wind blown out from an indoor unit is centered on the 2nd area | region 162A, the deflection means can deflect this blowing wind direction also to the 1st area | region 162B, and is normal The region (second region 162A) and the other region (first region 162B) can be partially co-operated.

Therefore, even if the air-conditioning chamber in which the indoor unit is installed is large, only the desired area in the air-conditioning chamber can be air-conditioned, and efficient air-conditioning can be performed as compared with air-conditioning in the entire air-conditioned chamber.

Since the relative position with respect to the indoor unit of a 1st area | region is selectable by a sub-remote control unit, setting of the area | region which cooperates is easy, and the 1st area | region can also be changed easily.

The presence or absence of a person in the area where the sub-remote control unit is arranged is detected by the person detecting means, and when the person is detected, the blowing wind is deflected to the first area, and when the person is not detected, the blowing wind is applied to the second area. Because of the deflection, it is possible to prevent air conditioning without the presence of a person in the first area, and to efficiently cooperate with only an arbitrary area in the air-conditioned chamber.

Therefore, according to the signal output from the sub-remote controller, the air-conditioning area in the air-conditioning room can be easily changed, resulting in a decrease in air-conditioning efficiency and waste of energy for air-conditioning by unnecessarily air-conditioning an unattended area. Without this, coordination of a short time zone with human beings becomes possible.

In the air conditioner 10, if the operation / stop operation can be performed in a state set in any one of the cooling operation, the dry operation, and the heating operation by the switch operation of the main remote controller 120, the operation in the set operation mode is started.

When the air conditioner 10 is operated and starts air conditioning, the air conditioner 10 measures the set temperature and the room temperature, and sets the operating frequency of the compressor 26 and the air flow rate (the number of revolutions of the cross flow fan) according to the measurement result. Then, the air conditioning operation is performed in accordance with this setting result.

In the outdoor unit 14, the four-way valve 24 is switched in accordance with the set operation mode. For example, when the cooling or dry mode is set, the refrigerant compressed by the compressor 26 is supplied to the heat exchanger 30 of the outdoor unit 14. Accordingly, the refrigerant compressed by the compressor 26 is liquefied by passing through the heat exchanger 30, and the liquefied refrigerant is supplied to the heat exchanger 18 of the indoor unit 12. The refrigerant supplied to the heat exchanger 18 of the indoor unit 12 vaporizes when passing through the heat exchanger 18 to cool the air passing through the heat exchanger 18.

On the other hand, during the heating operation, the four-way valve 24 is switched so that the high-pressure refrigerant compressed by the compressor 26 is supplied to the heat exchanger 18 of the indoor unit 12. Accordingly, the air passing through the heat exchanger 18 is heated when the high pressure refrigerant compressed by the compressor 26 is liquefied in the heat exchanger 18. The air heated by this heat exchanger 18 is blown out from the blower outlet 50 into a room, and a room is heated.

By the way, the indoor unit 12 of the air conditioner 10 is provided toward the main area 162A which mainly air-conditions in the air-conditioning room 162. FIG. As shown in Fig. 12, by placing the main remote controller 120 in the main area 162A, the air conditioner 10 is operated according to the temperature detected by a temperature sensor (not shown) in the main remote controller 120. The operation is performed so that the main area where the remote controller 120 is placed is in a desired air conditioning state.

On the other hand, in the air-conditioning chamber 162 which is air-conditioned by the air conditioner 10, the sub remote control 140 is provided in the sub area 162B different from the main area 162A. The sub-remote controller 140 is provided with a dome cover 154 toward the sub area 162B, for example, on a wall surface near the sub area 162B.

The sub remote controller 140 performs sensitivity adjustment by the adjusting knob 158A so as to detect a person in the sub area 162B with the human detection sensor 152. In addition, the sub remote controller 140 sets the position of the indoor unit 12 with respect to the sub remote controller 140 by the positioning switch 146.

The sub-remote controller 140 is operated by the power switch 160 on, so that the sub-remote controller 140 is surrounded by a signal indicating a position set by the positioning switch 146 (room temperature near the sub-area 162B). And presence or absence of a person in the sub area 162B.

When the air conditioner 10 receives the signal transmitted from the sub remote controller 140, the air conditioner 10 changes the initial position of the left and right flaps 52 in accordance with the setting of the positioning switch 146. For example, as shown in FIG. 9, when the positioning switch 146 is set to "center", the left and right flaps 52 swing in the predetermined angle range centering on the initial position C. As shown in FIG.

On the other hand, when the positioning switch 146 is set to "left", a swing is started in the predetermined swing range centering on the initial position L of the left-right flap 52. As shown in FIG. In addition, when the positioning switch 146 is set to "right", a swing is started in the predetermined swing range centering on the initial position R of the left-right flap 52. As shown in FIG.

As a result, for example, as shown in FIG. 11, the sub remote controller 140 is provided on the wall surface adjacent to the sub area 162B set on the right side toward the indoor unit 12, so that the positioning switch 146 is provided. If it is set to "left", the air-conditioning wind blown out from the indoor unit 12 causes the left and right flaps 52 to deflect at the initial position L to swing. Thereby, the air-conditioning wind blown toward the main area 162A is blown toward the sub area 162B.

In addition, the sub-remote controller 140 detects the temperature of the sub area 162B at a predetermined interval (for example, several minutes to several tens), and transmits the temperature to the indoor unit 12 of the air conditioner 10. When the indoor unit 12 of the air conditioner 10 receives the temperature (signal according to the temperature) transmitted from the sub remote controller 140, the sub area 162B is set to the set temperature (temperature set by the main remote controller 120). Control the temperature and air volume of the blowing wind. As a result, the sub area 162B is air-conditioned.

Thus, the air-conditioning wind blown out from the blower outlet 50 by the signal which designates the position from the sub remote control 140 is directed to the sub area 162B in which the sub remote control 140 is installed, I can cooperate. That is, the main area 162A and the sub area 162B in the same air-conditioning chamber 162 can blow out the air-conditioning wind toward another area, and can only cooperate with each area by one indoor unit 12. As shown in FIG.

Accordingly, the air-conditioning capacity is lowered as compared with the air-conditioning in the large air-conditioning room 162. In addition, only desired areas can be efficiently coordinated.

In addition, the sub-remote controller 140 detects the presence or absence of a person in the sub area 162B at a predetermined interval, and the air conditioner 10 receives the sub-remote controller 140 when the sub-remote controller 140 does not detect a person. The air conditioning wind is stopped toward the area 162B. This can prevent unnecessary air conditioning of the sub area 162B without people.

On the other hand, the main remote controller 120 is provided with a wind direction button 130 for converting the swing range of the left and right flaps 52, and by operating the wind direction button 130, the jet is deflected toward the sub area 162B. The wind direction of the wind can be directed toward the main area 162A.

Moreover, it is possible to set such that the blowing wind is blown out to both the main area 162A and the sub area 162B by the operation of the wind direction button 130.

That is, as shown in FIG. 10, the air conditioner 10 may cooperate with the main area 162A and the sub area 162B by the wind direction button 130 of the main remote controller 120. In this case, for example, the swing speeds of the left and right flaps 52 may be changed so that the difference between the temperature detected by the main remote controller 120 and the temperature detected by the sub remote controller 140 is small.

When the person is not detected by the sub-remote controller 140, the air-conditioning wind is transferred to the main area 162A (see FIG. 12), and the sub-remote controller 140 detects a person in the sub-area 162B. In this case, the air conditioning wind may be sent to both the main area 162A and the sub area 162B (see FIG. 10).

In this case, when the sub remote controller 140 detects a person in the sub area 162B without the wind direction button 13 being installed in the main remote controller 120, the air outlet 50 of the indoor unit 12 is automatically released. It may be possible to divert the direction of the vented air.

There are many people in the main area 162A where the main remote control 120 is mainly operated, but there are people in both the sub area 162B and the main area 162A, or a person in the main area 162A. There may be a case of temporarily moving to the sub area 162B, returning to the main area 162A after being in the sub area 162B for a few minutes. In these cases, by simultaneously coordinating the main area 162A and the sub area 162B, the sub area 162B can be co-conditioned as necessary while maintaining the main area 162A in a comfortable air conditioning state.

Thus, in the air conditioner 10 applied to this embodiment, the sub remote control 140 which sets the predetermined area of the air-conditioning room 162 in which the indoor unit 12 is installed is provided, and this sub remote control 140 is carried out. By deflecting the blowing wind toward the position set by the above, it is possible to focus intensively so that a specific area in the air-conditioning chamber 162 becomes a comfortable air-conditioning state.

As a result, since only the desired area in the large air-conditioning room can be efficiently co-operated so as to be comfortable, energy saving when the air-conditioner 10 air-conditions inside the air-conditioning room 162 can be achieved.

In the present embodiment, one main remote controller 120 and one sub remote controller 140 are described for one indoor unit 12, but a plurality of sub remote controllers 140 may be provided. As a result, a large room can be divided into a plurality of areas so that only each specific area can be efficiently air-conditioned.

In addition, in this embodiment, although the main remote control 120 and the sub remote control 140 which have a different function were used, you may use the remote control switch which combined both functions. That is, the main remote control unit 120 may have the position setting function of the sub remote control unit 140 combined, or the person detecting function and the on / off function of the remote control switch may be combined.

Thereby, the specific area in the air-conditioning chamber set by the remote control switch can be maintained in a desired air-conditioning state.

In addition, embodiment described above does not limit the structure of this invention. The present invention can be applied to an air conditioner of any configuration for air conditioning an air-conditioning room in which an indoor unit is installed.

As described above, according to the present invention, since the blowing direction of the blowing wind is deflected so that the blowing wind is blown toward at least one of the first region or the second region, only the predetermined predetermined area in the air-conditioned chamber is effectively air-conditioned. can do. Thereby, the outstanding effect that energy saving can be achieved, without impairing the comfort of a to-be-processed room.
