Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is a heat exchanger in which a U-shaped connecting pipe and a refrigerant pipe project from a side surface, and a heat exchanger arranged so as to partially project below the heat exchanger. The present invention relates to a side structure of an air conditioner having a drain pan.

<Prior Art> Conventionally, as a side structure of an air conditioner of this type, for example, there is one described in Japanese Utility Model Publication No. 62-1618. In this side structure, a U-shaped connecting pipe projecting from the side surface of a fin-tube type heat exchanger and a refrigerant pipe are covered with a synthetic resin cover, and the cover covers the connecting pipe. And a lead-out portion that guides the condensed water flowing down the main body portion to a drain pan arranged below, an extension cover portion that covers the refrigerant pipe, and a condensed water flowing down the extension cover portion to the drain pan. It is composed of a sloping guide portion and reliably collects water condensed in the connecting pipe and the refrigerant pipe in the drain pan without scattering.

<Problems to be solved by the invention> However, the above-mentioned conventional cover is merely a device for covering the connection pipe and the refrigerant pipe and collecting the water condensed on these pipes in the drain pan. Since the side portions are not completely shielded, there is a problem that conditioned air leaks from the gap between the lower end of the cover and the drain pan. Further, the cover does not sandwich and fix the refrigerant pipe between the extended cover portions, and does not have a structure to which an electric component box or the like can be attached. Therefore, a separate sealing member is required to prevent the conditioned air from leaking, and brackets, bands, and other metal fittings are required to secure the refrigerant pipes and electrical component boxes, increasing the number of parts and increasing the number of assembly steps. However, there is a drawback in that the cost of the product is increased.

Therefore, an object of the present invention is to devise a member to be attached to a side portion of a heat exchanger so as to simultaneously seal a conditioned air and fix a refrigerant pipe and an electric component box with a small number of parts and a small number of assembly steps. It is possible to provide a side structure of an air conditioner that can reduce the product cost.

<Means for Solving the Problems> In order to achieve the above object, the side structure of the air conditioner of the present invention has a U-shaped connecting pipe 5 and a refrigerant pipe 6 as illustrated in FIG. The protruding side surface 4a of the heat exchanger 4 and the upper surface of the drain pan 9 protruding from the lower part of the side surface are covered with a notch 10a through which the refrigerant pipe 6 is inserted, and the outer side surface slides the electrical component box 16. A box body 10 having a U-shaped cross section, which has a rail 11 that can be locked and is fixed to a side portion of an air conditioner, and a refrigerant pipe 6 that is inserted into the notch 10a.
It is characterized in that it is provided with a lid member 13 which has a holding portion 13a for holding down and which covers the upper portion of the box body 10.

<Operation> The box body 10 having a U-shaped cross section covers the side surface 4a of the heat exchanger 4 from which the U-shaped connecting pipe 5 projects and the upper surface of the drain pan 9 projecting from the lower part of the side surface, and cuts the upper part of the front surface.
