Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, and more particularly to improvements in a ventilation hole formed in a partition plate of an electrical component mounting box in an outdoor unit of an air conditioner and a waterproof cover thereof.

Conventionally, an outdoor unit of an air conditioner has been constructed as shown in FIG. The outdoor unit shown in Fig. 1 is disclosed in Japanese Utility Model Application No. 57-100163, in which 1 is a blower, 2 is a heat exchanger, and 3 is a heat exchanger.
is a compressor, 4 is a compressor room, 5 is an electrical equipment mounting box formed on the upper part of the compressor room 4, and 6 is a compressor room 4 and an electrical equipment mounting box for the blower room where the blower 1 is placed. 5, a notch formed in the upper part of the partition plate 6 in the part that partitions the electrical component mounting box 5, 8 a cover attached to this notch 7, 9 1 and 2 respectively show suction ports formed in the casing portion of the blower room in the outdoor unit.

By the way, the notch 7 formed in the partition plate 6
is the lead wire from the electrical component mounting box 5 (not shown)
In other words, it has the function of pulling out and connecting it to the blower 1 provided in the center of the heat exchanger 2, and also has the function of dissipating the heat generated from the electrical components in the electrical component mounting box 5. The blower 1 acts as an air path so that the air inside the electrical component mounting box 5 can be sucked and heat can be radiated. Therefore, since this notch 7 is provided in a position close to the upper suction port 9 of the outdoor unit, there is a risk that rainwater, etc. that enters from this suction port 9 may enter the electrical component mounting box 5, and this is prevented. As shown in FIG. 2, a waterproof cover 8 is attached to this notch 7 and has an air passage which also serves as an outlet for the lead wires.

That is, this waterproof cover 8 is formed in a shape as shown in FIG. 2, where 8a is a lead wire passage, 8b is a lead wire guide, and 8c is an air path for dissipating heat from inside the electrical equipment mounting box. , 8d indicate walls that prevent rainwater from entering from the outside.

The waterproof cover 8 in the outdoor unit of a conventional air conditioner has a shape as shown in FIG. It was not possible to attach it before the lead wire. In other words, when attaching the waterproof cover 8 to the notch 7 of the partition plate 6, the lead wire is applied to the lead wire passage part 8a, and the cover 8 is inserted into the notch 7 of the partition plate 6 in this state. I had to put it on. Therefore, the assembly workability is poor, and the cover must be removed even during service such as replacing the blower, and there is a risk that serious accidents may occur if the cover is forgotten to be attached at the end of service.

In addition, since the lead wire comes into direct contact with the notch 7 at the top of the partition plate 6, the end face of the sheet metal is curled, resulting in a complicated shape, which increases costs.Also, if a separate part is attached to protect it, the number of parts will be reduced. There were drawbacks such as an increase in the number of parts and poor assembly workability.

Therefore, an object of the present invention is to improve the notch formed in the partition plate that partitions the electrical component box and the waterproof cover attached to the notch so that the lead wire can be passed through without removing the waterproof cover. An object of the present invention is to provide an air conditioner equipped with an outdoor unit that can perform the following operations and protect the lead wires.

Hereinafter, the air conditioner of the present invention will be described in more detail with reference to preferred embodiments shown in the accompanying drawings.

3 and 4 show a partition plate 6 that partitions an electrical component mounting box in an outdoor unit and a waterproof cover 11 attached to the partition plate 6 in an air conditioner according to an embodiment of the present invention. .

The partition plate 6 is provided with a horizontal U-shaped notch 10 formed in the partition plate from its upper side edge.
A waterproof cover 11 is attached to this notch 10. This waterproof cover 11 consists of two plate members 1
3a and 13b are arranged at appropriate intervals to form a box shape with an open bottom and one side, and one plate member 1
An opening 16 is formed by cutting off the upper part of 3a, and a groove portion 12 extending downward from this opening 16 is formed.

Furthermore, a flange portion 14 projecting outward is formed on one open side edge of the waterproof cover,
In addition, the opening 16 is provided on the same plane as the plate member 13a.
A flange portion 15 is formed that projects from the edge of the flange. The other open side of the waterproof cover 11 is
When the casing of the outdoor unit is finally put on, its inner surface is tightly closed with the flange portion 14. Further, a rib 18 is formed on the waterproof cover 11 and extends parallel to the flange portion 15, thereby forming a mounting groove 19 into which the peripheral edge 10a of the notch portion 10 of the partition plate can be fitted. This rib 1
Reference numeral 8 acts as a holding portion for the partition plate 6, which also serves as a toy to prevent rainwater from entering the electrical equipment mounting box 5.

In the waterproof cover 11 having such a configuration, the opening 16 and the groove portion 12 serve as a passage for taking out the lead wires and also serve as an air passage for dissipating the heat inside the electrical component box. This waterproof cover 11 is attached to the peripheral edge 10a of the notch portion of the partition plate 6, with the space between the flange portion 15 and the rib 18 serving as a mounting groove 19.
Thereby, even if the waterproof cover 11 is attached to the notch 10 of the partition plate 6, the lead wire 17 can be taken in and out of the opening 16 opened on the side as long as the casing of the outdoor unit is removed.

As mentioned above, this invention is designed to maintain the outlet of the lead wire from the electrical component mounting box, protect the lead wire from the sheet metal edge, and release heat from the electrical component.
In addition, this one waterproof cover can prevent the infiltration of rainwater and the like. Further, since there is no need to remove the waterproof cover for wiring or taking out the lead wires, the assembly workability is extremely good, and the cost of the cover parts is extremely advantageous because it is made of integrally molded plastic.
