Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, the present invention proposes a screw 2 that fixes the compressor on the chassis of the electrical appliance. The screw 2 is connected to the chassis 1 of the electrical appliance. The end directly fixed to the chassis 1 is a circular plate, and the side facing away from the chassis 1 is vertical. The threaded column in the center of the circular plate is covered with a cylindrical shock-absorbing washer 3, and the space between the inner ring of the shock-absorbing washer 3 is used to install the fixing nut, and the compressor's mounting feet 4 are set on the shock-absorbing washer 3, so as to achieve the effect of shock absorption. Moreover, a threaded hole is provided on the end surface of the top end of the screw rod 2 for connecting the grounding wire 5 .

[0017] In the present invention, the fixing method of the screw rod 2 and the chassis 1 is welding, and other conductive fixing methods can also be used, all of which a...

Abstract

The invention discloses a screw, an electrical grounding structure of a compressor based on the screw, and an air conditioner, wherein the screw for fixing the compressor on a chassis of an electric appliance orderly crosses through an installing foot and a damping cushion ring of the compressor from top to bottom so as to fix the compressor on the chassis of the electric appliance; the installingfoot is sleeved at the upper end of the damping cushion ring and there is a gap between the installing foot and the outer circumference surface of the screw; the end part of the screw at one side ofthe installing foot is provided with a thread hole. By directly connecting the grounding wire with the screw for supporting the compressor installing foot, and then connecting with the chassis by means of the screw and effectively connecting with other metal parts of the air conditioners until an electric appliance box, thus the grounding system of the compressor is formed, and the grounding performance of the compressor is ensured.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an electrical grounding structure of a compressor, a compressor mounting screw for realizing the electrical structure, and an air conditioner adopting the electrical grounding structure of the compressor. Background technique [0002] As a driven fluid machine that elevates low-pressure gas to high-pressure gas, the compressor is the heart of the refrigeration system, so it is widely used in various refrigeration cycle systems such as refrigerators, air conditioners, and freezers. For safety, the shell needs to be effectively grounded. In the prior art, the grounding method of the compressor is directly connected to the ground screw of the electrical box through the ground wire on the compressor cylinder or the installation foot of the compressor, or connected to the middle partition of the outdoor unit through the ground wire Ground through ground continuity. If the ground...
