JPS61217633A - Power source cord connection construction for air conditioner - Google Patents

Abstract

PURPOSE:To make the work of power source cord connection easy and certain by providing a concave section on the side portion of a partition plate that faces the electricity room and collecting and storing the power source cord and its fixing band in the concave section. CONSTITUTION:A concave section 23 is formed integrally with a partition plate 21 on the side portion of the partition plate 21 which faces an electricity room 22, and a card connector 9 is fixed on the concave section 23 from outside. The cord connector 9, a main operation switch, temperature regulator and so on are connected by a cord that passes through a hole 29 that is provided at a portion of the concave section 23. With this arrangement, it is not necessary to take out an electric appliance support plate 28 from the main body of an air conditioner when it is installed to connect the power source cord to the connector 9, and the operation can be carried out very easily from the outside of the partition plate 21. Further, there is no possibility that the seal between the partition plate 21 and adjacent electric parts becomes imperfect and there is no possibility that cold air gets in and condensation develops on the electric parts.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power cord connection structure for an air conditioner.

The electrical component structure of a conventional air conditioner will be explained using a window type air conditioner shown in FIGS. 1 and 2.

The inside of the air conditioner is divided into an indoor side and an outdoor side by a partition plate 1, and the indoor side has an evaporator 2, a blower 3, and an electrical compartment 4.
is arranged, and a decorative cover 5 is provided on the front. The structure of the electrical component room 4 includes a main operation switch 7 on an electrical component support plate 6.
, a temperature regulator 8, etc. are fixed, and a power cord connector 9 is fixed from the inside of the electrical component support plate. The electrical component support plate 6 is fixed to the base plate 10 of the main body and the partition plate 1 with screws 11m and Ilb.

In a conventional air conditioner with such a structure, 1ζ
In order to connect the power cord (not shown) to the connector, it is necessary to remove screws 11M and 11b and open the electrical compartment, which has the drawback of poor workability. In addition, since the electrical components are the path for the cold air of the air conditioner, when fixing the electrical component support plate with screws 11m and 11b and restoring it to its original state after connecting the power cord, it is necessary to avoid contact with adjacent components. It was necessary to seal with great care.

If this sealing work is insufficient, there is a risk that when the air conditioner is operated for cooling, cold air will enter the electrical components, cooling the electrical components and causing dew condensation on their surfaces, resulting in poor insulation. It had

An object of the present invention is to eliminate the above-mentioned drawbacks of conventional air conditioners, and to make it possible to easily and reliably connect a power cord.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. FIG. 3 shows the structure near the cord connector of the electrical component part, and FIG. 4 shows a person-to-person cross section of FIG. 3.

Incidentally, in order to make it easier to understand the effects of the present invention, the power cord 25 that is attached at the time of installation is illustrated.

In the present invention, a concave portion 23 is formed integrally with the partition plate on the side surface portion of the partition plate 21 facing the electrical compartment 22, and the cord connector 9 is fixed to the concave portion 23 from the outside. The cord connector 9 is connected to the main operation switch, temperature controller, etc. by a cord passing through a hole 29 provided in a part of the recessed portion 23.

The depth of the concave portion 23 is greater than the height of the cord connector 9 so that there is no problem when the air conditioner main body is pulled out from the outer box during installation of the air conditioner.

Further, a power cord fixing band 24 is attached to the concave portion 23 near the cord connector 9 from the outside surface. A concave groove 27 is formed in the passage portion of the power cord 25 so that the power cord can be smoothly led to the outlet 26.

According to the present invention, when installing the air conditioner, the power cord 25
There is no need to remove the electrical component support plate 28 from the main body in order to connect the electrical component support plate 28 to the cord connector 9, and the work can be done extremely easily from the outside surface of the partition plate 21. The work of fixing the power cord 25 with the fixing band 24 can also be easily performed. In addition, the power cord 25 is connected to the cord groove 2 on the side of the partition plate.
By leading the power cord along line 7 to the outlet 26, no undue bending or force is applied to the power cord, which is also effective in preventing damage to the cord jacket.

Furthermore, since it is not necessary to remove the electrical component support plate 28 in order to connect the power cord, there is no possibility that the seal between the electrical component support plate and its adjacent parts will be incomplete during installation of the air conditioner. Therefore, it is possible to reliably eliminate the dangerous drawback that conventional air conditioners had, in which cold air enters the electrical components during cooling operation, cooling the electrical components and causing dew condensation on their surfaces.

In the above, an example has been described in which the recessed part 23 on the side surface of the partition plate is integrally formed with the partition plate 21, but in the case where the recessed part 23 is formed as a separate part from the partition plate 21 and fixed to the partition plate with screws. The same effect as above can also be obtained.
