Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a fan motor base mounting structure for an outdoor unit, and to an improvement measure for reducing the number of parts and reducing costs without impairing assembly workability.

(Prior Art) Conventionally, an outdoor unit of an air conditioner, in particular, an upper blow type outdoor unit in which cooling exhaust air is blown out above the outdoor unit, is disclosed, for example, in Japanese Utility Model Publication No. 57-2859. , A pair of left and right heat exchangers are provided, and stays are fixed to the tube plates at the front and rear ends of each heat exchanger,
A motor mount is mounted over these stays.

Further, in the upper blow type outdoor unit in which the heat exchangers are continuous in a U shape on the left and right sides and the rear side, as shown in FIG. 5, for example, as shown in FIG. And a pair of tube plates (21), (21), (22), (22) respectively, and the tube plates (21), (21), (22), (22) at the end and the center Stay (23),
(23) is fixed by welding and these stays (23), (23)
The fan motor mount (24) is mounted and fixed on the mount (Japanese Utility Model Publication No. 57-2859).

Further, as shown in FIG. 6, for example, a fan motor mount is provided on the inner surface of the fan top plate (25) through a cross-shaped stay (26).
Some are configured to fix (27).

(Problems to be solved by the invention) According to the fan motor base mounting structure of the outdoor unit disclosed in Japanese Utility Model Publication No. 57-2859, the capacity of the heat exchanger is relatively small, which is disadvantageous.

Further, in the conventional example shown in FIG. 5, the heat exchanger (20)
It is possible to increase the capacity of the heat exchanger (20)
Tube plate (22), (22) in the central part of the heat exchanger (20)
In addition to the complicated structure, the stays (23) and (23) are also required, which is disadvantageous in overall cost reduction.

Further, according to the conventional example shown in FIG. 6, since the motor mount is not supported by the heat exchanger, the configuration of the U-shaped heat exchanger is not complicated, but the fan top plate (25) is Stay (26),
In order to support the motor mount (27) and a motor (not shown), the fan top plate (25) cannot be made of lightweight synthetic resin, and the fan top plate (25) has a stay (26) and a motor mount ( 2
7) and the fan top plate (25) after assembling the motor (not shown)
It is necessary to assemble, stay (26), motor mount (27)
Also, the weight and size of the fan top plate (25) when assembled are increased by the motor, and the workability of assembling the fan top plate (25) is impaired.

The present invention has been made in view of the above points, and an object thereof is to reduce the cost by omitting the tube plate and the stay in the central portion of the U-shaped heat exchanger without impairing the workability of mounting the fan top plate. It is about trying to go down.

In this case, the side plate supports the load of the motor mount and the motor, and it becomes necessary to provide the side plate with reinforcement for preventing deformation due to the load. However, adding an angle member or the like to the side plate as a reinforcement increases the number of parts, which is disadvantageous in terms of cost reduction.

Therefore, an object of the present invention is to increase the strength of the side plate without increasing the number of parts and prevent the side plate from being deformed by the load of the motor mount, the motor and the fan.

(Means for Solving the Problems) In order to achieve such an object, in the present invention, by supporting the motor mount on the side plate, the U-shaped heat is increased without increasing the load burden on the fan top plate. The tube plate and stay at the center of the exchanger are omitted.

As a concrete means for solving the problem, in the device according to claim (1), as shown in FIGS. 1 and 2, the upper edge portion of the side plate (5) of the outdoor unit is bent inward to receive the base receiving portion. (8) is formed, and the motor mounting base (11) is fixed to the base receiving portion (8).

Further, in the invention related to (2), particularly, the configuration of the side plate (5) is specified, and the side plate (5) is recessed in a groove shape in the portion extending from the base receiving portion (8) of the side plate (5) to the lower side thereof. The reinforcing ribs (9) thus formed are formed.

(Operation) With the above configuration, the motor mounting base (11) is supported by the base receiving portion (8) formed by bending the upper edge of the side plate (5) inward, and thus the central portion of the heat exchanger. The tube sheet and stay can be omitted. Further, since the fan, the motor and the motor mounting base (11) are supported by the side plate (5), it is not necessary for the fan top plate to support these loads, and the fan top plate can be made of lightweight synthetic resin. It is not necessary to increase the weight and size of the fan top plate at the time of assembling by the fan, the motor and the motor mount (11), and the workability of assembling the fan top plate is not impaired.

Further, in particular, in the invention according to claim (2), since the reinforcing plate (9) is formed by recessing the side plate (5) in a groove shape, the side plate (5) is formed by press molding one plate. The reinforcement and the reinforcement can be formed at low cost, the strength of the side plate (5) can be increased without increasing the number of parts, and the side plate (5) can be prevented from being deformed by the load of the motor mount (U), the motor and the fan.

(Effect of the Invention) As described above, according to the inventions according to claims (1) and (2), the motor mount (11) is supported by the side plate (5), so that the fan top plate The tube plate and stay in the center of the heat exchanger can be omitted without increasing the weight and size of the fan, motor, and motor mount (11) during assembly, and the workability of assembling the fan top plate is improved. It is possible to reduce the number of parts and reduce the cost without damaging the cost.

Particularly, according to the invention of claim (2), the side plate (5) and the reinforcing rib (9) can be formed at low cost by press-molding one plate, and the side plate (5) can be formed without increasing the number of parts. It is possible to increase the strength of 5) and prevent the side plate (5) from being deformed by the load of the motor mount (11), the motor and the fan.
