[Problems to be solved by the invention]
In the above-mentioned conventional outdoor units, the same type of outdoor units having different capacities have been commercialized so as to be compatible with various air conditioning capacities. When commercializing the same type of outdoor units having different capacities, the size of the heat exchanger, the number of compressors, and the like are changed according to the air conditioning capacity. For this reason, it is necessary to change the size of the casing and the size of the top plate in plan view according to the size and arrangement of various devices.
[0005]
However, when manufacturing outdoor units with different air-conditioning capacities by changing the size of the casing and the size of the top plate, it is necessary to manufacture various types of parts and store them in the parts storage area. turn into. In addition, if the size of the top plate is increased in accordance with the increase in the air-conditioning capacity, the dimensional accuracy at the time of molding tends to decrease, so that it is particularly difficult to form the air outlet with high accuracy, which adversely affects the blowing performance of the blower fan. There is also a possibility that it will.
[0006]
On the other hand, there is a case in which the size of the casing in a plan view is increased to be a plurality of times the size of the top plate, and a divided structure in which a plurality of top plates having the same shape is mounted on the casing. In such a divided structure of the top plate, since the size of the casing and the top plate in plan view is determined by the size of the blower fan, a wasteful space is generated in the planar arrangement of the heat exchanger, the compressor, and the like. As a result, the sizes of the casing and the top plate may not be optimized.
[0007]
An object of the present invention is to obtain an optimum casing size in accordance with a change in air conditioning capacity, and to prevent an excessively large component storage space for components constituting an outdoor unit.

The second portion has a second engagement portion that engages with the first engagement portion such that the first portion and the second portion are relatively immovable on the first side.
[0013]
In this outdoor unit, problems such as a displacement after assembling the first part and the second part hardly occur.
In the outdoor unit of the air conditioner according to claim 5, in claim 4, the first engagement portion has a shape along the air outlet.
In this outdoor unit, since the first engagement portion is formed along the air outlet, the distance from the edge of the air outlet to the outer portion of the first portion is equalized. At the time of forming one part, it can contribute to prevention of shrinkage of the material.
[0014]
The outdoor unit of the air conditioner according to claim 6 is the outdoor unit according to any of claims 2 to 5, wherein the ventilation plate is a resin molded product.
In this outdoor unit, the ventilation plate has a divided structure of the first portion and the second portion. Therefore, even when the ventilation plate is a resin molded product, the mold can be shared and the size can be reduced. The cost of the mold can be reduced.
[0015]
In the outdoor unit of the air conditioner according to claim 7, in claim 6, the ventilation plate has a long side dimension of 900 mm or more and a short side dimension of 700 mm or more.
Since this outdoor unit is a large-sized resin ventilation plate having a long side dimension of 900 mm or more and a short side dimension of 700 mm or more, the effect of cost reduction of the mold by division becomes remarkable.
[0016]
An outdoor unit of an air conditioner according to claim 8 is the air conditioning apparatus according to claim 6 or 7, wherein the air outlet has a diameter of 650 mm or more.
In this outdoor unit, since the ventilation plate has an air outlet having a diameter of 650 mm or more, the ventilation plate is divided into a first portion including the air outlet to reduce the size of the component, and thus the other portion is provided. In comparison with this, it is easier to form an air outlet that requires higher dimensional accuracy.
