DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for controlling the air in a room to be air-conditioned provided with an indoor unit.

[0002]

2. Description of the Related Art Air conditioners (hereinafter referred to as "air conditioners").
Air-conditioned air is blown into the room to be air-conditioned by passing through a heat exchanger of an indoor unit (indoor unit) provided in the room to be air-conditioned to blow air into the room to be air-conditioned. ing. The installation position of the indoor unit of such an air conditioner is preferably a position at which the conditioned air can be blown out to the whole area 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 brought into a desired air-conditioning state.

In recent years, the room to be air-conditioned in which an indoor unit is provided is becoming wider, and its shape is diversified, for example, it is formed in an L-shape or the like. In addition, the mounting position of the indoor unit needs to avoid windows, doors, beams, and the like, and is often restricted. Therefore, in order to uniformly air-condition the entire area of a large room with one indoor unit, an air conditioner having a high air-conditioning capacity is required.

[0004] However, from the viewpoint of energy saving, it is not preferable to uniformly air-condition the entire area of a large room. In other words, even if the room is large, the space where people are present is often limited, and air conditioning the entire area of the large room will spread temperature-controlled air to spaces without people,
This means that it is necessary to further increase the air conditioning capacity.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and efficiently air-conditions a desired position in a large room without impairing the comfort of the room to be air-conditioned. The purpose of the present invention is to propose an air conditioner capable of performing the above.

[0006]

The invention according to claim 1 is
An air conditioner for air-conditioning by blowing out temperature-controlled air from an outlet of an indoor unit to an air-conditioned room to which an indoor unit is attached, wherein the air conditioner specifies a predetermined position in the air-conditioned room with respect to the indoor unit. And a deflecting means for biasing the temperature-controlled air blown out from the outlet toward a position specified by the position specifying means.

According to this invention, the deflecting means deflects the direction of the blown wind toward the position specified by the position specifying means.

[0008] The blowing air blown from the indoor unit is usually centered on the front of the indoor unit. The deflecting unit can partially air-condition a region different from the normal region by directing the direction of the blown wind to the position specified by the position specifying unit.

Therefore, even if the room to which the indoor unit is attached is large, it is possible to air-condition only a desired area of the room to be air-conditioned, which is more efficient than air-conditioning the entire area of the room to be air-conditioned. Air conditioning becomes possible.

According to a second aspect of the present invention, the position specifying means includes a position setting means and a transmitting means for outputting a predetermined signal based on the setting of the position setting means. Characterized in that it is a remote control switch mounted at the position of (1).

According to the present invention, the blown air is deflected toward the position set by the remote control switch. Thereby, it is possible to efficiently perform air conditioning so that only an arbitrary area in the room to be air-conditioned is comfortable.

According to a third aspect of the present invention, the remote controller switch is a sub remote controller provided separately from a main remote controller for setting an operation state of the indoor unit, and the sub remote controller is located in the air-conditioned room. It is characterized by being arranged in a region different from the region to be cut.

According to the present invention, the position specifying means is provided as a sub remote controller different from the main remote controller for setting operating conditions and the like. The main remote controller is usually placed in an area where a person is present in the room to be air-conditioned, while the sub remote controller can be placed in a position (place) where a person stays shorter than the place where the main remote controller is placed. .

[0014] Thus, when the area in which the main remote control is placed is air-conditioned, the air-conditioning air is deviated by the main remote control, whereby air-conditioning can be performed in an area where people are short.

The invention according to claim 4 is characterized in that the deflecting means is activated and deactivated by a signal from the position specifying means.

According to the present invention, when the position is designated by the position designating means, or when a signal designating the position is sent, the deflecting means is operated, and the designation is canceled or the position is designated. When the signal stops, the operation of the deflecting means is stopped. Thereby, the area to be air-conditioned in the room to be air-conditioned can be easily switched.

The invention according to claim 5 is characterized in that the position specifying means includes a selecting means for selecting any one of a plurality of preset relative positions with respect to the indoor unit.

According to the present invention, the position to be air-conditioned can be selected and designated by the selection means, so that the setting of the area to be air-conditioned is simplified. Further, the designated area can be easily changed.

The invention according to claim 6 includes a person detecting means for detecting the presence or absence of a person in an area designated by the position designating means, and activates the deflecting means according to a detection result of the person detecting means. It is characterized by the following.

According to the present invention, the presence / absence of a person at the position (in the area) designated by the position designation means is detected by the detection means and the operation of the deflection means is stopped when no person is detected. Thereby, it is possible to prevent air-conditioning in a state where no person is present in the area specified by the position specifying means. Energy consumption can be suppressed.

The initial positions of the left and right flaps 52 are changed in accordance with the setting of. For example, as shown in FIG. 9, when the position setting switch 146 is set to “center”, the left and right flaps 52 swing around the initial position C within a predetermined angle range.

On the other hand, when the position setting switch 146 is set to “left”, the left and right flaps 52
The swing is started in a predetermined swing range around the initial position L. When the position setting switch 146 is set to “right”, the left and right flaps 52
The swing is started within a predetermined swing range around the initial position R.

Thus, for example, as shown in FIG. 11, the sub remote controller 140 is mounted on the wall surface adjacent to the sub area 162B set on the right side toward the indoor unit 12, and the position setting switch 146 is turned on. When “left” is set, the conditioned air blown from the indoor unit 12 swings while the left and right flaps 52 are biased to the initial position L. As a result, the conditioned air blown out toward the main area 162A is blown out toward the sub area 162B.

The sub remote controller 140 operates the sub area 162B at predetermined intervals (for example, several minutes to several tens of minutes).
Is detected and sent to the indoor unit 12 of the air conditioner 10. The temperature of the indoor unit 12 of the air conditioner 10 transmitted from the sub remote controller 140 (a signal corresponding to the temperature)
Is received, the temperature and amount of the blown air are controlled so that the sub-area 162B becomes the set temperature (the temperature set by the main remote controller 120). Thereby, sub-area 162B is air-conditioned.

As described above, the air-conditioning air blown out from the outlet 50 is directed to the sub-area 162B to which the sub-remote control 140 is attached by the signal designating the position from the sub-remote control 140, so that the sub-area 162B is air-conditioned. Can be. That is, the main area 162 in the same air-conditioned room 162 in one indoor unit 12
The air-conditioning air is blown toward different areas of A and the sub-area 162B, and only the respective areas can be air-conditioned.

As a result, the air-conditioning capacity can be reduced as compared with the case where the entire area of the large room 162 is air-conditioned. Also,
Only the desired area can be efficiently air-conditioned.

In sub remote controller 140, human detection sensor 152 detects the presence or absence of a person in sub area 162B at regular intervals. 162
The blowing of the conditioned air toward B is stopped. This can prevent unnecessary air conditioning of the sub area 162B where there are no people.

On the other hand, the main remote controller 120 has a wind direction button 130 for switching the swing range of the left and right flaps 52.
By operating the wind direction button 130, it is possible to direct the wind direction of the blowing wind deviating toward the sub area 162B to the main area 162A.

By operating the wind direction button 130, it is possible to set so that the blown air is blown out to both the main area 162A and the sub area 162B.

That is, as shown in FIG. 10, the air conditioner 10
The main area 162A and the sub area 162B
Air conditioning can be performed. In this case, for example, the temperature detected by the main remote controller 120 and the sub remote controller 14
For example, the swing speed of the left and right flaps 52 may be changed so that the difference between the temperatures detected by 0 is reduced.

When no person is detected by sub remote controller 140, air-conditioning air is sent to main area 162A (see FIG. 12). When sub remote controller 140 detects a person in sub area 162B, main area 162A is detected. Control may be performed so that the conditioned air is sent to both of the sub-areas 162B (see FIG. 10).

In this case, air conditioning blown out from the outlet 50 of the indoor unit 12 automatically when the sub remote control 140 detects a person in the sub area 162B without providing the wind direction button 130 on the main remote control 120. The direction of the wind can be switched.

The main area 162A where the main remote controller 120 is mainly operated is often occupied by a person. However, when a person is present in both the sub area 162B and the main area 162A, or when a person is present in the main area 162A. Temporarily moves to sub-area 162B, and moves to sub-area 1 for several minutes.
After staying at 62B, the user may return to the main area 162A. In these cases, by air-conditioning the main area 162A and the sub-area 162B at the same time, the sub-area 162B can be air-conditioned as necessary while maintaining a comfortable air-conditioning state of the main area 162A.

As described above, in the air conditioner 10 applied to the present embodiment, the sub remote controller 14 for setting a predetermined area of the air-conditioned room 162 in which the indoor unit 12 is provided.
0 is provided, and the blowout air is deviated toward the position set by the sub remote controller 140, so that the air conditioning can be mainly performed so that a specific area in the air-conditioned room 162 is in a comfortable air-conditioning state. .

As a result, since it is possible to efficiently air-condition only a desired area in a large room to be air-conditioned to be comfortable, it is possible to save energy when the air-conditioning room 162 is air-conditioned by the air conditioner 10.

In the present embodiment, one main remote controller 120 and one sub remote controller 140 have been described for one indoor unit 12.
A plurality of units 40 may be provided. Thus, a large room can be divided into a large number of areas, and only a specific area among them can be efficiently air-conditioned.

In the present embodiment, the main remote controller 120 and the sub remote controller 1 each having different functions are provided.
Although 40 is used, a remote control switch having both functions may be used. In other words, the main remote control 120 may have the position setting function of the sub remote control 140, and furthermore, a human detection function and turning on of the remote control switch.
_You may have _/ off function together.

Thus, a specific area in the room to be air-conditioned set by the remote control switch can be maintained in a desired air-conditioning state.

The above-described embodiment does not limit the configuration of the present invention. INDUSTRIAL APPLICATION This invention is applicable to the air conditioner of an arbitrary structure which air-conditions the air-conditioned room in which an indoor unit is provided.
