Abstract

<P>PROBLEM TO BE SOLVED: To provide a wall-mounting type air conditioner allowing air blow noise to be reduced and formed by allowing design images to be unified. <P>SOLUTION: A wall-mounting type indoor unit 2 is formed by allowing the heat exchange part 44 and the air blow part 63 thereof to be divided, making the outer diameter of the heat exchange part 44 to that of the air blow part 63 generally equal, and connecting the heat exchange part 44 to the air blow part 63. Since an air blow part 63a with large air blow capacity can be fitted to the heat exchange part 44, the air blow capacity can be increased even if the rotational speed of an indoor air blow fan 34a is not increased to reduce air blow noise. In addition, since the air blow part 63 and the air blow part 63a are formed in the same depth and height dimensions, the design images of the wall-mounting type indoor unit 2 and the wall-mounting type indoor unit 2a can be unified. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wall-mounted air conditioner that forms a model having a plurality of indoor unit capacities by combining a heat exchange capacity of an indoor heat exchanger and a blowing capacity of an indoor blower.
[0002]
[Prior art]
In conventional wall-mounted air conditioners, the outdoor unit is generally installed outdoors, and the indoor unit is generally installed above the indoor wall surface. The indoor unit includes a frame of the indoor unit mounted on the wall, an indoor heat exchanger is mounted at a position slightly above the center of the frame, and a cross flow fan extending horizontally below the indoor heat exchanger. Indoor blower is installed. An indoor unit having a front grille having an inlet on the front surface and a top surface, and a front grille having an outlet on the lower front surface, is attached to the front of the frame so as to cover the indoor heat exchanger and the indoor blower from the front. The main body is configured.
[0003]
And the capacity configuration of this indoor unit is configured by including the indoor heat exchangers having different heat exchange capacities and the indoor blowers having different air blowing capacities into the same indoor unit main body. When configuring an indoor unit having a small capacity, an indoor heat exchanger having a small heat exchange capacity and an indoor blower having a small blowing capacity are provided. A large indoor heat exchanger and an indoor blower having a large blowing capacity are provided, and a model is configured to secure a predetermined capacity (for example, see Patent Document 1).

[Problems to be solved by the invention]
However, when configuring an indoor unit having a large capacity, it was necessary to provide an indoor heat exchanger having a large heat exchange capacity. However, the indoor unit of this wall-mounted air conditioner was installed on a wall surface as described above. In many cases, the location of the wall surface to which the indoor unit is attached is a place where the height is restricted, such as on a window, due to recent housing circumstances and the like. Therefore, the indoor heat exchanger having a large heat exchange capacity and the indoor blower having a large air blowing capacity have to be housed in the indoor unit main body whose height dimension is limited.
[0006]
However, as described above, since the indoor heat exchanger having a large heat exchange capacity is mounted above the indoor unit, the indoor blower of the indoor blower cannot be increased in size. The number of rotations must be increased to improve the blowing capacity. Further, if there is no limit on the location of the wall on which the indoor unit is installed, it was possible to increase the size of the blower fan, but due to the increase in the size of the indoor blower fan, the design of the indoor unit, Since the indoor unit is different from the indoor unit with the small capacity, the design image could not be unified.
[0007]
For this reason, the indoor unit having a large capacity has a problem that the noise at the time of blowing increases when the design image is unified, and it has been required to solve this problem.

FIG.
[0041]
The blower 63a has a wider width of the indoor blower fan than the blower 63 and can increase the amount of blown air. Therefore, even if the rotation speed of the indoor blower fan 34a is reduced, the blower capacity is equivalent to that of the indoor blower fan 34. Therefore, it is possible to configure the wall-mounted indoor unit 2a in which the blowing sound is reduced while maintaining the same performance as the wall-mounted indoor unit 2. The width of the blower 63a is wider than that of the blower 63, but the dimensions in the depth and height directions are the same as those of the blower 63. Therefore, the design images of the wall-mounted indoor unit 2 and the wall-mounted indoor unit 2a are different. Can be unified.
[0042]
Further, FIG. 6A is a front sectional view of the wall-mounted indoor unit 2 configured by combining the heat exchange unit 44 and the blower unit 63 described above, similarly to FIG. 5A. FIG. 6B is a front cross-sectional view of a wall-mounted indoor unit 2b configured by combining the same blower unit 63 as in FIG. 5A with, for example, a heat exchange unit 44a wider than the heat exchange unit 44. It is. The heat exchange section 44a accommodates an indoor heat exchange section 64 that is wider than the indoor heat exchanger 20.
[0043]
Since the width of the indoor heat exchanger 20 (see FIG. 4) and the amount of heat exchange are large, the heat exchange unit 44a can reduce the amount of air blown by the indoor blower fan 34 as compared with the heat exchange unit 44. The wall-mounted indoor unit 2b in which the blowing sound is reduced can be configured. The width of the heat exchanging unit 44a is wider than the heat exchanging unit 44, but the dimensions in the depth and height directions are the same as those of the heat exchanging unit 44. Therefore, the wall-mounted indoor unit 2 and the wall-mounted indoor unit 2b Design image can be unified.
[0044]
As described above, by combining the heat exchange unit having substantially the same dimensions in the depth and height directions and the blower unit, a plurality of types of indoor units can be configured by unifying the design image.
[0045]
【The invention's effect】
From the above description, the heat exchange section and the blower section of the indoor unit can be divided, and the outer diameters of the heat exchange section and the blower section are substantially equal, so that the heat exchange section and the blower section Can be arbitrarily combined, so that it is possible to reduce the blowing noise and to provide a wall-mounted air conditioner with a unified design image.
