Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art Conventionally, an air conditioner having an indoor unit and an outdoor unit is often used as a so-called room air conditioner. As shown in FIG. 6, a conventional indoor unit (100) has a horizontally long unit casing (1).
01) contains an indoor heat exchanger and a blower,
The air outlet (102) was formed in an elongated shape in the left-right direction. This type of indoor unit (100) is installed near the ceiling on the wall surface of the room, and blows the air (104) heated or cooled by the indoor heat exchanger obliquely downward from the vicinity of the ceiling.

[0003]

However, in the indoor unit (100), since the air (104) is blown down from near the ceiling, temperature unevenness is likely to occur in the vertical direction in the room.

In some cases, the air (104) blown out from the air outlet (102) is blown directly to the occupant (106), which tends to give a sense of draft.

Further, when air-conditioning a large space such as a living room, it is difficult to blow air over a wide range in the left-right direction because there is a certain limit to the blowing angle of the flap provided in the blowing port (102).

Further, when the air conditioner is installed over two rooms, it is impossible to centrally perform air conditioning in one of the rooms.

The present invention has been made in view of the above points, and has as its object to reduce uneven temperature in the vertical direction, reduce the feeling of draft, blow air into a wide area,
And zoning air conditioning.

It is configured to be rotatable.

[0010] In the above air conditioner, the air heated or cooled by the indoor heat exchanger is blown into the room from an air outlet elongated in the vertical direction. Therefore, the blown air is supplied over a wide range in the vertical direction, so that the temperature unevenness in the vertical direction in the room is reduced.

Further, since the unit casing is configured to freely rotate in the left-right direction, the direction of the blown air is changed by rotating the unit casing, thereby reducing a feeling of draft, blowing air to a wide area, and zoning. Promotion of air conditioning is achieved.

[0012] An air conditioner according to a second aspect of the present invention is the air conditioner according to the first aspect, wherein the air outlet comprises first and second air outlets whose blowing directions are different by 90 degrees or substantially 90 degrees in the left-right direction. It includes the outlet.

In the above air conditioner, the air heated or cooled by the indoor heat exchanger is blown out from at least the first and second air outlets. Since the air outlets of the two air outlets are different from each other by 90 degrees or almost 90 degrees in the left-right direction, the air is blown over a wide range.
In addition, by blowing out air so as to enclose the occupants from the left and right, the feeling of draft is reduced.

An air conditioner according to a third aspect of the present invention is the air conditioner according to the first or second aspect, further comprising a vertically extending rotation shaft fixed to the unit casing, wherein the unit casing is provided with the rotating shaft. It is configured to rotate according to the rotation of the shaft.

In the above air conditioner, by rotating the rotating shaft, the unit casing performs a so-called swinging operation in the left-right direction, thereby changing the air blowing direction.

An air conditioner according to a fourth aspect of the present invention is the air conditioner according to the third aspect, wherein the rotation shaft is formed in a cylindrical shape, and the rotation shaft is formed by a flexible pipe inside the room. A communication pipe connecting the heat exchanger and the outdoor pipe is housed therein.

In the above-mentioned air conditioner, since the connecting pipe connecting the indoor heat exchanger and the outdoor pipe is formed by a flexible pipe, it is not damaged even if the rotating shaft rotates. Therefore, the communication pipe can be accommodated inside the rotating shaft, and the indoor unit can be downsized.

An air conditioner according to a fifth aspect of the present invention is the air conditioner according to the fourth aspect, wherein:
A drain pump is housed therein.

In the above air conditioner, since the drain pump is also housed inside the rotating shaft, the size of the device is further reduced.

An air conditioner according to a sixth aspect of the present invention includes
In the air conditioner according to any one of the fifth inventions,
It has a drive motor for rotating the rotating shaft.

In the above air conditioner, since the rotating shaft is driven by the drive motor, the change of the blowing direction can be automated.

An air conditioner according to a seventh aspect is the air conditioner according to the second aspect, wherein the indoor unit comprises 2 units.
It is installed so as to straddle two rooms.

In the above air conditioner, one of the rooms can be intensively cooled or heated by rotating the unit casing. As a result, suitable zoning air conditioning can be realized.

[0024]

As described above, according to the present invention, air is blown out from an air outlet having a vertically elongated shape.
It is possible to reduce temperature unevenness in the vertical direction in the room. In addition, since the unit casing is configured to be rotatable in the left-right direction, the direction of air blowing can be changed over a wide range, thereby reducing the feeling of draft, blowing air over a wide range, and promoting zoning air conditioning. .

The blowing direction is 90 degrees in the left-right direction or almost 9
By providing two air outlets that differ by 0 degrees, air can be blown out so as to enclose the occupants in the room from the left and right, and the sense of draft can be further reduced.

The indoor unit can be reduced in size by housing a communication pipe connecting the indoor heat exchanger and the outdoor pipe inside the rotary shaft. By forming the communication pipe by a flexible pipe, damage to the communication pipe can be reliably prevented. Further, by housing the drain pump inside the rotating shaft, the indoor unit can be further downsized.

By providing a drive motor for rotating the rotating shaft, the change of the blowing direction can be automated.

As shown in FIG. 1, when the casing (20) is rotated rightward and directed toward the living room (2), the air (61) blown out from the first air outlet (21) is discharged to the living room. The air (62) is blown out to the boundary between (2) and the kitchen (3), and the air (62) blown out from the second air outlet (22) is blown out along the wall surface of the living room (2). As a result, both the blown air (61, 62) flows along the boundary and the wall surface so as to wrap the resident (not shown) of the living room (2). Therefore, the resident does not easily feel the draft feeling. In this case, an air curtain is formed by the air (61) blown out from the first air outlet (21).

Further, since the air (62) blown out from the second air outlet (22) flows along the wall surface, the invasion of radiant heat from the wall surface can be effectively suppressed.

In particular, since the blown air (61, 62) is blown out in a shape spread in the vertical direction, air can be blown out over a wide range from the floor surface to the ceiling. Therefore, the temperature unevenness in the vertical direction in the room can be reduced, and the comfort in the room can be improved.

Further, since the air is blown out along the wall surface or the boundary of the room, it is possible to supply hot air or cold air to a wide area in the left-right direction. Further, since air can be blown out so as to enclose the occupants, a sense of draft can be reduced.

Since the casing (20) can be rotated left and right, the direction of the air outlets (21, 22) can be changed by the rotation of the casing (20). Air conditioning can be performed. That is, zoning air conditioning of the living room (2) or the kitchen (3) can be performed.

In the above embodiment, the drive motor (6
Although the rotating shaft (52) is rotated by 5), the rotating shaft (52) may be rotated manually. The drive motor (65) can be omitted.
