Description

[Detailed Description of the Invention] The present invention relates to an outdoor unit of an air conditioner that includes a protective guard on the outside of a heat exchanger.

An embodiment of the present invention will be described below based on the drawings. 1 is a U-shaped heat exchanger placed vertically on a box-shaped bottom plate 2, and 3 is a U-shaped heat exchanger that closes a U half-opening 4 of the heat exchanger. An exterior panel 5 is a box-shaped top plate that spans over the heat exchanger 1 and the exterior panel 3 and covers from above, and 6 is a blower 8 located below the exhaust lower part of the top plate, and a blower motor 9. These three supports are used to hang and fix the heat exchanger 1 below the top plate 5, and these members form an outdoor unit, which takes in outside air from three sides of the heat exchanger 1 and discharges it upward from the exhaust lower. It becomes.

10.10 is a fixture for the top plate 5 installed on the bottom plate 2,
When assembling the top plate 5, the fixing parts 11a, 11b and the edges 12a, 12b of the supports 6a, 6b are placed close to each other at the upper end points 13a, 13b of the heat exchanger 1. A roughly U-shaped auxiliary tool 14.14 is fitted, and at the same time, the upper edge of the synthetic resin protective guard 15 disposed outside the heat exchanger 1 is clamped and fixed. There is.

16.16 is a holder for positioning and fixing the U-shaped heat exchanger 1 on the bottom plate 2, and the same R-shaped pressing part 19 that is applied to the R-shaped inner edge portion 18.18 of the densely packed plate fins 17 is used. have.

Therefore, in the assembly order of the outdoor unit, first heat exchanger 1 is assembled.
is placed on the bottom plate 2, and the holder 16.16 is applied to the fin-dense portion of the R-shaped inner edge portion 18.18 where the fin strength is increased, and the holder 16.16 is clamped and fixed between the rising peripheral edge 20 of the bottom plate 2. At the same time, the lower edge of the protective guard 5 is inserted from above between the lower end of the heat exchanger 1 and the peripheral edge 20, and then the auxiliary tool 14
．． At 14, the upper end portions 13 a and 13 b of the heat exchanger 1
and the upper edge of the protective guard 5 at the same time, and both side edges of the protective guard 5 are engaged with the tube plates 21, 21 of the heat exchanger 1 with the locking tools 22, 22, and the protective guard 5 is secured. It is securely attached around the outside of the heat exchanger 1.

Thereafter, the exterior panel 3 is assembled, the top plate 5 is placed from above, and the fixtures 10 and 10 are used to secure the exterior panel 3, thereby completing the assembly of the outdoor unit I.

During such assembly, the fixing parts 11 of the three supports 6 fixed to the inner wall of the top plate 5 are placed as close as possible to the outer circumference of the exhaust lower, but in order to make the outdoor unit more compact. When assembling the top plate 5, especially when the edge-shaped edges 12a and 12b of the fixing parts 11a and 11b are attached to the upper end portion 1 of the heat exchanger 1,
3a and 13b, so if the top plate 5 is shifted to one side and assembled, the edges 12a and 12a
There is a risk that the fins 17 at the upper end portions 13a and 13b and the heat exchange refrigerant pipes passing through the fins may be damaged and the refrigerant may leak.
The heat exchanger 1 is protected at the same time by receiving the edges 12a and 12b on the inner walls 23 and 23 of the heat exchanger 1.

As described above, according to the present invention, by using the auxiliary tool having a substantially U-shaped cross section, it is possible to prevent damage to the heat exchanger due to the edge of the blower support, and at the same time, it is possible to fix the protective guard. This makes it possible to provide an extremely useful outdoor unit.
