Problems solved by technology

[0012] But in the existing hermetic compressor as mentioned above, since the lower cover 1c of the casing 1 and the triangular supporting plate 2 are two parts made separately, they are assembled together by welding, so when assembling During the process, there will be a certain gap between the lower cover 1c and the triangular supporting plate 2
The resulting problem is: when the compressor is driven, metal friction sounds will be generated between the two parts as the machine vibrates

Embodiment Construction

[0027] The noise reduction structure of the hermetic compressor of the present invention will be described in detail below based on the embodiments shown in the drawings.

[0028] image 3 with Figure 4 Is an exploded side view and a cross-sectional view of an assembled state of an embodiment of the hermetic compressor of the present invention, Figure 5 It is a cross-sectional view of a part of the oil storage part of the lower cover pallet in the hermetic compressor of the present invention, Figure 6 It is a longitudinal cross-sectional view of the body mounting protrusion of the lower cover tray in the hermetic compressor of the present invention.

[0029] As shown in the figure, the hermetic compressor of the present invention is composed of an electric structural part and a compression structural part. The electric structural part is fixedly installed inside the casing 10 and can generate rotational force when the power is turned on. The compression structure component is c...

Abstract

The present invention discloses noise reducing structure of sealed compressor. The sealed compressor includes casing, electric structure part and compression structure part inside the casing. The electric structure part produces the drive force, and the compression structure part connected to the electric structure part to suck in, compress and excellent fluid. The sealed compressor includes also lower cover backing plate to close the casing and fix the casing onto the installation plane. The lower cover backing plate has such structure that there is downward notched oil storing part with at least two different curvatures in the middle part. The present invention can eliminate metal contacting noise produced between different parts, improve the noise characteristic of the lower cover backing plate, and thus lower the noise of the compressor obviously.

Description

Technical field [0001] The present invention relates to a supporting device for a closed compressor, more specifically, to a structure for reducing noise of a closed rotary compressor (STRUCTURE FOR REDUCING NOISE OF HERMETIC COMPRESSOR), and its purpose is to support the support of the compressor body The plate is made with several curvatures and thereby reduces vibration. Background technique [0002] As we all know, a compressor is a device that compresses fluid. Such a compressor is generally composed of an electric structure component and a compression structure component, wherein the electric structure component can transmit power, and the compression structure component can use the power generated by the above-mentioned electric structure component to compress a fluid. A compressor in which such electric structural components and compression structural components are installed in the same sealed casing is called a sealed compressor. [0003] The underside of the casing of ...
