Frame support apparatus of closed compressor

Abstract

The present invention provides a frame support device for a hermetic compressor, which includes a hermetic casing, a frame, an upper brake protrusion, and a lower brake protrusion. In the first embodiment, two pairs of The springs are wound in the opposite direction. Among the four springs in the second embodiment, the front end springs located on both sides of the front end of the frame are wound in opposite directions. And the winding direction of the rear end spring corresponding to the front end spring is opposite, so the winding direction of the front end spring and the rear end spring at the diagonal position are the same. With the frame supporting device of the electric compressor of the present invention, since the frame is supported by springs wound in opposite directions, the spring forces in the horizontal vibration direction cancel each other out. Therefore, the vibration of the frame is effectively reduced, the vibration noise of the compressor is reduced, and the performance of the product is improved.

Description

technical field [0001] The invention relates to the field of compressors. Background technique [0002] The present invention is an invention of a hermetic compressor, figure 1 A sectional view showing the internal structure of a hermetic compressor in the prior art. As shown in the figure, the upper cabinet 1 t and the lower cabinet 1 b constitute a closed cabinet 1 , and a frame 2 is provided inside the sealed cabinet 1 . A stator 3 is fixed on the frame 2, and the frame 2 is supported inside the airtight casing 1 by a spring 2S. [0003] figure 2 Shown is a detailed sectional view of an inner frame support device of a hermetic compressor in the prior art. Refer below figure 2 , the supporting device of the frame 2 through the spring 2S will be described in detail. That is to say, the upper end of the spring 2S is inserted into the braking protrusion 2' below the frame 2, and the lower end of the spring 2S is inserted into the braking protrusion 1b' fixed on the lo...

AI Technical Summary

Problems solved by technology

Among them, the vibration in the vertical direction can be effectively reduced by the spring 2S, but the vibration in the horizontal direction cannot be reduced

[0014] This is because the spring 2S has little effect on lateral vibration, and the spring 2S is wound along the same winding direction. The compressor frame support spring 2S is a coil spring, and the coil spring has two winding directions: left-handed and right-handed. First, the existing compressors usually use support springs with the same winding direction, and the vibration in the horizontal direction will be superimposed on each other, so the effect of reducing the vibration in the horizontal direction is low
