Description

Description: TECHNICAL FIELD The present invention relates to an outdoor unit assembly structure for an air conditioner.

[Prior Art] FIG. 4 is an exploded perspective view showing a housing of an outdoor unit of an air conditioner disclosed in Japanese Utility Model Publication No. Sho 63-42270, in which (11) denotes a compressor, a heat exchanger and It is an L-shaped base plate on which a blower and the like are placed, and integrally has a rising rear plate (13) having an intake port (12) for outside air. (14) is a front cabinet having a top plate (15) and an exhaust port (16) opened in the front. The front cabinet (14) and the base plate (11) are combined in front and rear to form both ends. A cylindrical body having an open portion is formed, and the openings at both ends are respectively provided on the side plates (1).
7) Blocked by (18).

That is, the heat exchanger, the compressor, the blower and the like are mounted on the base plate (11), and after the refrigerant pipe is brazed, the front cabinet (14) is attached, and finally the side plates (17) (18) ) Is attached so that the outdoor unit can be assembled.

[Problem to be Solved by the Invention] Since the outdoor unit in the conventional air conditioner is configured as described above, the brazing operation of the refrigerant pipe is specified on the front and side surfaces, and the brazing locations are limited. A heat exchanger can be placed only from the front side. In addition, since the base plate is formed as an integral L-shape, there is a problem that it is difficult to carry or store the base plate.

The present invention has been made in order to solve the above-described problems. In addition to enabling the work of brazing the refrigerant pipes from the back side, the base plate is also formed in a dish shape so that the transportation and storage efficiency can be improved. The purpose is to be.

[Means for Solving the Problems] In the case of the present invention, a compressor, a heat exchanger, a blower, and the like are placed on the bottom opening of a U-shaped front cabinet which is opened up and down and has an exhaust port at the front. Sealed with a dish-shaped base plate provided with a valve mounting plate that fixes a refrigerant pipe connection valve at one corner, and a left-hand edge of this base plate with a catching claw at the top for sucking outside air A back wall composed of a net and a back plate adjacent to the net is disposed, and the entire top opening is covered with a detachable top plate, and the hook is engaged with the upper portion of the heat exchanger. Thus, the net is held.

[Operation] In the case of the present invention, the base plate is dish-shaped and provided with a valve mounting plate, and a compressor, a heat exchanger, and a blower are mounted on the base plate, and the refrigerant fixed to the valve mounting plate. After brazing the refrigerant pipe to the pipe connection valve, the front cabinet, rear wall and top plate are assembled to the base plate, so that the work of brazing the refrigerant pipe can be made easier from all directions, and furthermore, the heat exchanger Is not specified. Further, the net for sucking outside air is held by the engagement of the hooking claw with the heat exchanger.

Example An example of the present invention will be described below. FIG. 1 is a schematic diagram showing a positional relationship between components. That is, in FIG. 1, (1) is a dish-shaped base plate on which a compressor, a heat exchanger, a blower and the like are mounted, and (2) is a base plate (1) at one corner of the rear edge. A valve mounting plate provided for fixing a refrigerant pipe connection valve, (3) a rear plate provided immediately above the valve mounting plate and a series of rear plates, and (4) a suction port for outside air located on the side of the valve mounting plate. And is arranged on the rear edge of the base plate (1) together with the back plate (3) to form a series of back walls. (5) is a U-shaped front cabinet which is opened up and down, has an exhaust port (6) at the front, has an outside air inlet (7) on one side, and has a bottom opening formed by the base plate (1). It is closed. (8) is a top plate which is detachably mounted on the front cabinet (5) so as to cover the top openings of a series of rear walls on the front cabinet (5). In summary, the rising edge of the base plate (1) is surrounded by a front cabinet (5), a back wall and a valve mounting plate (2). In the above configuration, after mounting the compressor, the heat exchanger, the blower, and the like on the base plate (1), the refrigerant pipe and the like are brazed to, for example, a refrigerant pipe connection valve fixed to the valve mounting plate (2), Thereafter, a rear wall composed of a front cabinet (5), a net (4) and a rear plate (3) is arranged around the base plate (1), and a top plate (8) is detachably mounted on these. The outdoor unit can be assembled by mounting.

FIG. 2 is a perspective view showing a hook of a unit (4) forming a part of the rear wall of FIG. 1, and in this case, two L-shaped hooks are provided on a plastic net (4). A hook claw (9) is provided, and this hook claw (9) is hooked on the upper part of the built-in heat exchanger (10) as shown in FIG. .

[Effect of the Invention] The outdoor unit of the air conditioner according to the present invention is configured such that a bottom opening of a U-shaped front cabinet having an exhaust port opened on the front side which is opened up and down as described above is used for a compressor, a heat exchanger, a blower, and the like. With a valve mounting plate that fixes the refrigerant pipe connection valve at one corner, and sealed with a dish-shaped base plate. A back wall composed of a net for inhaling outside air and a back plate adjacent to the net was disposed, and the entire top opening was covered with a removable top plate and hooked on the upper part of the heat exchanger. Since the net is held by the hooks, the workability of assembling the outdoor unit on the line is good, and the occupancy efficiency is improved without taking up space when storing and transporting the base plate, and including the mounting of the net. All equipment There are advantages such as easy and quick assembly of the body.
