Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical equipment cover for a separate type air conditioner.

[0002]

2. Description of the Related Art In recent years, in air conditioners as well, improvements in product safety and reliability are required due to the enforcement of the PL Law. Along with this, resin parts have been widely used due to rationalization of parts configuration and complicated shapes, but it has become necessary to make resin materials flame-retardant and to make them incombustible by adding metal materials.

With reference to the drawings, an example of an electrical equipment cover for an electric wire connecting portion for connecting an outdoor unit to an outdoor unit of a conventional separate type air conditioner will be described below. FIG. 4 is a schematic view showing an electrical cover of an outdoor unit of a conventional separate type air conditioner. In the figure, 7 is an outdoor unit, 8 is a metal outer box, and 9 is an indoor / outdoor unit connection electric wire connecting portion configured by providing an opening in a part of the metal outer box 8. Further, 10 is a resin electric component cover, which also serves as a tote during transportation. A metal cover 11 is installed on the back surface of the resin electric component cover 10 by adhesion, welding, screwing, or the like.
2 is attached to the main body of the outdoor unit 7. The opening of the metal outer box 8 is covered with the metal cover 11, and the electrical component of the outdoor unit is protected by the non-combustible material.

FIG. 5 is a schematic view showing another example of the electrical equipment cover of the outdoor unit of the conventional separate type air conditioner. In the figure, 7, 8 and 9 are the same as in the above example. Reference numeral 13 is a resin electric component cover, which also serves as a tote during transportation. The resin electric component cover 13 is attached to the main body of the outdoor unit 7 with a screw 14, and a metal cover 15 is attached to the main body of the outdoor unit 7 with a screw 16 inside the resin electric component cover 13.

The electrical cover of the outdoor unit of the separate type air conditioner configured as described above can prevent deformation and damage of exterior parts due to heat radiation from the inside of the outdoor unit.

The power supply cover of the second example not only prevents the exterior parts from being deformed or damaged due to heat radiation from the inside of the outdoor unit, but also when the resin electric component cover is deformed or damaged by heat from the outside or the like. Can also protect the electrical components.

[0007]

However, in the conventional electrical cover of the separate type air conditioner, when the resin electrical cover is deformed or damaged by heat from the outside, the metal cover is lifted or detached, and the like. The electrical component could not be sufficiently protected. Further, if the metal cover is provided separately from the resin cover, there is a possibility of forgetting to attach the cover during the installation work.

In view of the above problems of the prior art, the present invention ensures that the external components are not deformed or deformed due to heat radiation from the inside.
An object of the present invention is to realize an electrical component cover for an outdoor unit of a separate type air conditioner, which is capable of preventing damage and protecting the electrical component portion from heat from the outside.

[0009]

In order to solve the above-mentioned problems, the electrical equipment cover of the outdoor unit of the separate type air conditioner of the present invention is an electric wire for connecting indoor and outdoor units in which an opening is provided in a part of a metal outer box. In the connection part, a metal cover is installed on the back surface of the resin cover, and the resin cover and the metal cover are fastened together with screws to the outdoor unit body.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION With the above means, the present invention makes it possible to prevent the deformation and damage of exterior parts due to heat radiation from the inside without forgetting to attach them, and further to protect the electrical equipment part from the heat from the outside. The present invention realizes an electrical cover for an outdoor unit of a type air conditioner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electrical equipment cover of an outdoor unit of a separate type air conditioner of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of an outdoor unit of a separate type air conditioner according to the present invention. FIG. 2 is a rear view of the electrical equipment cover of the outdoor unit, and FIG. 3 is a sectional view of the electrical equipment cover mounting portion. In the figure, 1 is an outdoor unit, 2 is a metal outer box, and 3 is an indoor / outdoor unit connection electric wire connecting portion formed by providing an opening in a part of the metal outer box 2. Further, 4 is a resin electric component cover, which also serves as a tote during transportation. A metal cover 5 is installed on the back surface of the resin electric component cover 4 by adhesion, welding, screwing, or the like. Further, the resin electric component cover 4 and the metal cover 5 are provided.
Are fastened to the main body of the outdoor unit 1 with screws 6. The opening of the metal outer box 2 is covered with the metal cover 5, and the electrical component of the outdoor unit is protected by the noncombustible material.

The electrical cover of the outdoor unit of the separate type air conditioner configured as described above has the resin electrical cover 4 and the metal cover 5 integrated so that they are not forgotten to be attached and are radiated from the inside. Deformation of exterior parts
The damage can be prevented, and even if the resin electric component cover is deformed or damaged by heat from the outside or the like, the metal component cover can be protected without floating or detachment of the metal cover.

[0013]

As is apparent from the above-described embodiments, the electrical equipment cover of the outdoor unit of the separate type air conditioner of the present invention is provided at the indoor / outdoor unit connection electric wire connection portion where the opening is provided in a part of the metal outer box. By installing a metal cover on the back side of the resin cover and tightening the resin cover and the metal cover together with the outdoor unit body with screws, it is possible to make sure that you do not forget to install and heat dissipation from the inside It is possible to prevent deformation and damage of the exterior parts due to, and also to protect the electrical component from heat from the outside.
