Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an outdoor unit of an air conditioner, and more particularly to an improvement in the mounting structure of a blower holding member.

[Conventional technology]

The outdoor unit of this type of conventional air conditioner has a configuration as schematically shown in FIG. 4. To explain this simply, the fan 2 constituting the blower l was attached to the motor 3 and fixed to the outdoor unit casing 5 side by the blower holding member 4. In other words, in the conventional device, "double fan 2
is usually attached from the front side of the projecting body 5, and -
The configuration is such that actual air is sucked in from the back of the casing 5 and blown out from the front of the casing 5. In the outdoor unit shown in Figure 1, the inside of the housing 5 is partitioned into left and right parts, with the left side in the figure being a blower room 6 and the right side being a machine room 7. Also, 8 in the figure
is the heat exchanger, and 9 is the pressure 1? is the machine.

Conventionally well-known outdoor units generally have the above-mentioned configuration, but when installing multiple outdoor units together, it is important to consider installing many outdoor units in a narrow space. Therefore, it has been thought that a structure having a structure in which air is sucked in from the front surface of the housing 5 (suction port 10) and blown out from the top surface (air outlet 11) as shown in FIG. 5 is effective. When adopting such a structure, in order to further reduce the installation area of the outdoor unit, one machine room 7 is concentrated in the lower part of the blower room 6, and the blower room 6 and machine room 7 are divided into seven parts.
It was partitioned below.

That is, in the outdoor unit of the air conditioner as described above, the mounting structure of the blower 1 can be mainly divided into two types, the first of which is a blower holding member as shown in FIG. 4 is fixed vertically to the casing 5, and the lower part is fastened to the casing base 5a and the upper part to the back panel 5b. The structure was such that the holding member 4 was directly fixed to a front panel 5C having a bell mouth 12 forming an air path (intake port 10).

[Problem that the invention seeks to solve]

'1 However, according to the former structure described above, the bell mouth and front panel (not shown in FIG. 4) that form the air passage with the blower holding member 4 are temporarily attached to the housing base 5a or other Since they are fixed at respective positions via members, there is a drawback that the coaxiality of the fan 2 and the bell mouth, which is an important element to ensure the performance of the blower 1, is not accurate.

Furthermore, in the former structure, the air passage (6) and the machine room 7 are partitioned, as in the case of an outdoor unit in which the machine room 7 and electrical parts are concentrated in the lower part of the housing 5 as shown in FIG. In order to have sufficient strength to allow the separator 14 to hold the fan 2 and motor 3, the housing 5 must be
It was necessary to increase the overall strength, and it also had structural problems. In addition, in the former case mentioned above, the separator (not shown in Figure 4) that partitions the blower room 6 and the machine room 7 is removed during service such as maintenance and inspection of the machine room 7. It is necessary that
From this point of view as well, the above-mentioned structure has many problems.

On the other hand, although the latter structure is the most reliable method for aligning the centers of the bell mouth 12 and fan 2, since the motor 3, fan 2, etc. are directly fixed to the front panel 5C, the front panel 5C itself is It becomes very heavy, which reduces work efficiency during assembly, and also when performing maintenance services such as maintenance inspection, when the front panel 5C is removed, the fan 2 etc. are also removed, and this is removed from the housing 5. It has disadvantages such as being inconvenient when working because it cannot be attached to the side.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to assemble the blower and the bell mouth while maintaining the centering accuracy, thereby improving workability during assembly and during services such as maintenance and inspection. The purpose is to obtain an outdoor unit for an air conditioner.

[Means for solving problems]

The outdoor unit of the air conditioner according to the present invention has a shape that allows the blower holding member and the member having the bell mouth etc. forming the air passage to be directly fixed, and the fixing portion between the blower holding member and the casing is fixed to the above-mentioned air It is characterized by being provided at a location different from the path forming member, and in addition, it has a structure in which the blower holding member is arranged horizontally.

[Effect]

According to the present invention, by directly fixing the blower holding member and the air passage forming member having a bell mouth, etc., the coaxiality accuracy of the fan and the bell mouth is improved, and the blower holding member is fixed to the air passage forming member other than the air passage forming member. By fixing and holding the parts to the housing side, workability during assembly and services such as maintenance and inspection is improved.
