Embodiment 1

[0045] figure 1 It is a structural schematic diagram of the rotary compressor of Embodiment 1, specifically, the rotary compressor of Embodiment 1 includes:

[0046] a compressor body and a casing sleeved outside the compressor body;

[0047] The compressor body includes a motor assembly 100 and a pump body assembly 200;

[0048] The pump body assembly includes an upper cylinder cover 210, a lower cylinder cover 230, and a cylinder 220 disposed between the upper cylinder cover and the lower cylinder cover.

[0049] In Embodiment 1, the circumferential outer edge of the upper cylinder head 210 extends upwards to form a circumferential side wall, which is called a frame 240 herein, and the frame 240 is integrated with the upper cylinder head 210, namely The upper cylinder head and the frame are an integrated structure, and the motor assembly 100 is placed in the space formed by it and the upper part of the casing 300 of the compressor, and the motor assembly 100 is placed in t...

Embodiment 2

[0056] image 3 It is a structural schematic diagram of the rotary compressor of embodiment 2, specifically, the rotary compressor of embodiment 2 includes:

[0057] a compressor body and a casing sleeved outside the compressor body;

[0058] The compressor body includes a motor assembly 100 and a pump body assembly 200;

[0059] The pump body assembly includes an upper cylinder cover 210, a lower cylinder cover 230, and a cylinder 220 disposed between the upper cylinder cover and the lower cylinder cover.

[0060] In Embodiment 2, the circumferential outer edge of the cylinder 220 extends upwards to form a circumferential side wall, which is called a frame 240. The difference between the frame 240 of Embodiment 2 and the frame of Embodiment 1 is that Embodiment 2 The frame 240 and the cylinder 220 are integrally provided.

[0061] Likewise, a first damping assembly 400 is provided between the lower cylinder head 230 and the housing 300 in the second embodiment. The first ...

Abstract

The invention provides a rotor compressor which comprises a compressor body, a shell body and a rack, wherein the shell body is arranged outside the compressor body in a sleeving manner;the compressor body comprises a motor assembly and a pump body assembly; the pump body assembly comprises an upper cylinder cover, a lower cylinder cover, an air cylinder; the air cylinder is arranged between the upper cylinder cover and the lower cylinder cover; the rack is integrally arranged with the circumferential outer edge of the upper cylinder cover or the circumferential outer edge of the air cylinder; and a first vibration-reducing assembly is arranged between the lower cylinder cover and the shell body. Through the first vibration-reducing assembly between the lower cylinder cover and the shell body of the rotor compressor, through a second vibration-reducing assembly between the rack and the shell body, as well as through the flexible connection at an air suction port, mechanical vibrations generated by the motor assembly and the pump body assembly of the rotor compressor can be effectively absorbed and converted, thereby eliminating the vibration coupling between the compressor assemblies, and greatly prolonging the service life of the rotor compressor, and effectively reducing the noise of the rotor compressor.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor with a damping function. Background technique [0002] The rotary compressor includes a shell, and a motor assembly and a pump body assembly are housed in the shell. The pump body assembly includes an upper cylinder head, at least one cylinder, and a lower cylinder head. The rotary compressor uses the rotational force of the motor to work. Specifically, the motor assembly is used to generate driving force, the pump body assembly is used to compress refrigerant, the crankshaft passes through the through hole on the compressor frame, its upper end is connected to the motor assembly, and its lower end is connected to the pump body assembly, and the motor assembly The rotational force is transmitted to the pump body assembly for compressing the refrigerant. [0003] Traditionally, the rotary compressor is welded to the shell through the upper cylinder head or the cylin...
