Description

[Detailed Description of the Invention] The present invention relates to a heat exchanger protection structure for an air conditioner, and has been made in order to provide reliable protection of the heat exchanger by making it inexpensive and compact.

The heat exchanger of an air conditioner generally consists of fins made of thin aluminum plates, copper pipes and plates through which refrigerant passes, and is placed facing the outside air.

Since the fins are thin aluminum plates, they are easily damaged and can easily cause scratches on the human body if they come into contact with them, so it is necessary to protect the heat exchanger by covering it with a net or other means.

A conventional protection structure for a heat exchanger is shown in FIGS. 1 and 2.

1 is a heat exchanger in which an upper plate 2 and a lower plate 3 are arranged facing each other, a large number of fins 9 are arranged between each plate, holes are made in the upper plate 2, lower plate 3, and fins 9, and a pipe 4 is formed. is inserted, and a refrigerant is passed through the pipe 4 for heat exchange.

The upper plate 2 and the lower plate 3 are provided with an ascending section 12 and a descending section 13 for each chamber to prevent the plates from deforming due to heat during pipe welding or the like.

A propeller fan 8 is rotated by a fan motor 7 and sends air to the heat exchanger 1.

5 is an outer box that covers the outer body of the air conditioner.

6 is the base, on which parts are placed.

Reference numeral 10 is a net having a hook portion 11 formed on its upper portion, and the hook portion 11 is hooked onto a rising portion 12 to cover and protect the heat exchanger 1.

The upper part of the net 10 is sandwiched between the rising part 12 of the upper plate 2 and the outer box 5, and the lower part is sandwiched between the rising part 13 of the lower plate 3.
and the base 6 to prevent the net 10 from moving.

In the conventional heat exchanger protection structure described above, the net 1
When manufacturing the net 10, the hook part 11 must be formed into a U-shape, making the net 10 expensive.

Furthermore, since the net 10 is interposed between the upper plate 2 and the outer box 5 and between the lower plate 3 and the base 6, the size of the air conditioner increases by the thickness of the net 10.

Furthermore, there was also a drawback that the left and right positions of the net 10 were not determined.

The present invention was made to improve the above-mentioned drawbacks, and will be explained below with reference to an embodiment shown in FIGS. 3, 4, 5, and 6.

Note that the same reference numerals as in FIGS. 1 and 2 represent the same parts and the same functions, so a description thereof will be omitted.

The heat exchanger 14 has an upper plate 15 and a lower plate 1 facing each other.
A large number of fins 1 are arranged between the upper plate 15, the lower plate 17, and the fins 1, and holes through which the pipes 4 are passed are provided in the upper plate 15, the lower plate 17, and the fins 1.

Further, a hole 21 is provided in the surface of the upper plate 15 where the hole 20 is made, and a hole 22 is provided in the rising portion 18 of the lower plate 17.

These holes 21. The hole 22 can be machined at the same time as the hole 20 is drilled.

On the other hand, the upper end of the net 19 is not processed, and the lower end is bent at the bent part 23.
Form it.

To attach the net 19, bend it and open the hole 21. as shown by the two-dot chain line A. It can be easily attached by inserting it into the hole 22.

Since the bent portion 23 of the attached net 19 is inserted into the hole 22, the attached net 19 does not move vertically or horizontally, and is securely attached.

In the heat exchanger protection structure of the present invention described above, there is no U-shaped bending for hooking, and only step bending is required, the net structure is simple, and the structure of the net is simple. Since the net 19 is inserted into the holes 21 and 22,
Since the mounting position is secure and there is no need to sandwich the net 19 between the plate, the outer box 5, and the base 6 to fix the net 19, it has the advantage that the external dimensions can be reduced.
