Abstract

PURPOSE:To make the installation status of an air-conditioner stable by a method wherein a casing where a heat exchanger and a fan are accommodated has a larger width at the upper part than at the lower part, and the upper part is installed in the space above a ceiling of a building. CONSTITUTION:The width A of an upper part 9 of an indoor unit 1 is larger than the width B of a lower part 10, and the upper part 9 is fixed by a fixing device 12 that is hung on a ceiling 11 to accommodate the upper part 9 in the space 13 above the ceiling. An indoor fan 14 is housed in the upper part 9, an air outlet 15 is formed on the front, and an air outlet member 17 of a ceiling board 18 is connected to a fan duct 16. An indoor heat exchanger 22 and a drain pan 23 are enclosed in the lower part 10 and a suction grille 24 is formed on the front. By this constitution mentioned above, the indoor fan 14 that has the largest width among equipment can be accommodated in the upper part 9, and the width B of the lower part 10 can be made small by installing the indoor heat exchanger 22 vertically as far as possible. Therefore, the installation status of an air-conditioner having an unstable shape can be made stable and noise can be reduced.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which the upper part of the housing is wider than the lower part.

0002

2. Description of the Related Art Conventionally, an air conditioner placed on the floor of a room requires a larger installation space than a ceiling-mounted air conditioner or a wall-mounted air conditioner. Therefore, in order to reduce the installation space as much as possible,
No. 498 discloses an air conditioner in which the lateral (width) dimension of the lower part of the casing is smaller than the lateral (width) dimension of the upper part, so that the entire casing has a substantially T-shaped structure.

0003

[Problem to be solved by the invention] Although installing such an air conditioner on the floor reduces the installation space,
The upper horizontal (width) dimension of this air conditioner is the lower horizontal (width)
Since it was larger than the actual size, there was an undeniable feeling of instability. or,
Since the air conditioner was installed on the floor, there was a problem in that the floor in this area could not be cleaned.

An object of the present invention is to provide a sense of stability in the installed state of an air conditioner in which the width of the upper part is larger than that of the lower part.

[0005]

[Means for Solving the Problems] In order to achieve this object, the present invention provides a method in which an upper part, the width of which is larger than the lower part, is housed within the ceiling space of a house so that only the lower part is exposed indoors. This is what I did.

[0006]

[Operation] Since the upper part, which has a larger width, is stored in the ceiling space, only the lower part, which has a smaller width, can be seen from inside the room.

[0007]

[Embodiment] FIG. 1 shows a first embodiment of the present invention.
1 is an indoor unit, 2 is an outdoor unit, and both units 1,
2 are connected by a refrigerant pipe 3 to form an air conditioner 4. The outdoor unit 2 houses an outdoor heat exchanger 5, an outdoor fan 6, and a compressor 7.

8 is a housing of the indoor unit 1, and its upper part 9
The width dimension A of is set larger than the width dimension B of the lower part 10. This upper part 9 is fixed by a fixture 12 suspended from a ceiling 11 and housed in a ceiling space 13. In addition, an indoor blower (
A centrifugal fan 14 is housed therein, and a discharge port 15 is formed in the front surface thereof. Here, since the width dimension A of this upper part 9 is set larger than the width dimension B of the lower part 10, an indoor fan 14 whose depth dimension is larger than the width dimension B of the lower part 10 can be stored in this upper part 9. .

[0009] Reference numeral 16 is connected to the discharge port 15 by a ventilation duct and is housed in the ceiling space 13. 17 is the ceiling board 18
It is connected to the air blowing duct 16 by a blowing member provided in the air blowing member. Incidentally, a plurality of the blowing members 17 may be provided on the ceiling plate 18 and connected to the blowing duct 16 as necessary. A lower part 10 of this housing 8 extends downward from its upper part 9, and its lower end 19 is in a state of floating above the floor surface 21 of the room 20.

[0010] In this lower part 10, an indoor heat exchanger 2 is installed.
2 and a drain pan 23 are built in, and a suction grill 24 is formed on the front surface thereof.

When the air conditioner 4 configured as described above is operated, indoor air is introduced from the suction grille 24 into the lower part 10 as shown by the solid line arrow, and the introduced air flows through the lower part 10.
It ascends through zero space and is heated or cooled by the indoor heat exchanger 22. Then, the heated or cooled air is guided to the air blowing duct 16 via the indoor blower 14, and the blowing member 1
It is blown downward from 7.

[0012] With such a configuration, the housing 8
Since the indoor blower 14, which has the largest width dimension among the devices housed inside, is housed in the upper part 9 of this housing 8, the indoor heat exchanger 22 housed in the lower part 10 of this housing 8 should be erected as vertically as possible. Accordingly, the width dimension B of this lower portion 10 can be reduced. This reduces the installation space for the housing 8. Moreover, the housing 8 of such an air conditioner
Since the housing 8 is suspended from the ceiling, the lower end 19 of the housing 8 can be raised above the floor 21 of the room 20, thereby making it easier to clean the floor 21. Incidentally, if the lower part 10 floats above the floor surface 21 and the user feels unstable, the lower end 19 may be extended to the floor surface (not shown).

Furthermore, since the upper part 9 of the housing 8 is housed in the ceiling space 13, the upper part 9 can be enlarged relatively freely. Therefore, by housing the indoor fan 14, which is relatively large enough to provide a sufficient amount of air even when the rotational speed of the blades is reduced, in the upper part 9, noise can be reduced.

FIG. 2 shows a second embodiment of the present invention, and the first difference from the embodiment shown in FIG. It is. The second difference is that the lower surface 31 of the upper part 9 of the housing 8 and the ceiling plate 18 are made substantially flush with each other, and air is discharged from the air outlet 32 provided on the lower surface 31. That's true. By arranging the lower part 10 of the housing 8 along the indoor wall surface 30 in this manner, the space in the indoor room 20 can be widely utilized.

FIG. 3 shows a third embodiment of the present invention, and the first difference from the embodiment shown in FIG. 34 is located approximately at the center of the room 20. The second point is that suction grills 35 are provided on both sides of the lower part 34 of the housing. The third one is an indoor blower 37 housed in the upper part 36 of the housing 33.
A centrifugal blower with double-blowout type is used, and blower ports 15 are provided on both sides of the upper part of the blower so that blower ducts 16 are connected to the blower. By providing such an air conditioner in the center of the room, the lower part 34 of the housing 33 can also be used as a partition member for the room 20, and each partitioned room 3
8 and 39 can be heated and cooled by this air conditioner.

In FIGS. 2 and 3, parts that are the same as those in FIG. 1 are designated by the same reference numerals, and their explanations are omitted.

[0017]

[Effects of the Invention] As described above, in the present invention, the upper part of the housing, which has a large horizontal dimension, is housed in the ceiling space, and the lower part, which has a smaller horizontal dimension than the upper part, is exposed indoors. The installation state of an air conditioner having an unstable shape can be made stable.

Furthermore, if the blower, whose width (depth) is difficult to reduce, is housed in the upper part, where the width is large, and the heat exchanger, whose width (depth) is relatively easy to reduce, is housed in the lower part,
By reducing the width (depth) of this lower portion, the interior living area can be made larger.
