Description

Lower support module of compressor rotating assembly

Technical Field

The utility model relates to the technical field of compressors, in particular to a lower support module of a compressor rotating assembly.

Background

The working principle of the refrigerator compressor is that the low-temperature low-pressure refrigerant gas is sucked from the air suction pipe, the piston is driven to compress by the operation of the rotating component, and then the high-temperature high-pressure refrigerant gas is discharged to the air discharge pipe to provide power for refrigeration cycle. Reciprocating inertial force and rotational inertial force during operation of the compressor may cause the compressor to vibrate. The vibration support plate of the compressor is transferred to the cabinet of the refrigerator, resulting in the problem of excessive vibration and noise of the refrigerator. Therefore, optimization and upgrading of compressor vibration isolation and damping technology becomes particularly important.

In the chinese patent of patent No. CN115370553a, a "compressor and a vehicle-mounted refrigerator" are disclosed, where a stator component of the compressor includes a stator core and an insulating framework mounted on the stator core, where the insulating framework is provided with a buffer component, the buffer component is located between the stator component and the housing, and the buffer component is made of a non-metallic material. Through the buffer assembly to make when the compressor receives to rock or jolt, the pump body can with the casing contact when rocking for the casing, and avoid the pump body to be in direct contact with the casing, thereby play the cushioning effect to the pump body and casing. Because the buffer component is made of nonmetallic materials, the buffer component has smaller sound when colliding with the shell, thereby playing a role in reducing noise. The insulating framework and the stator core are mutually matched, the buffer component is complex in shape, so that the die structure of the insulating framework is complex, and production and assembly are difficult. The buffer component is required to be buffered with a limiting piece additionally arranged on the compressor shell, and the stator component is difficult to be placed in the lower shell, so that the production and assembly efficiency of the compressor is low. In addition, 3 leads of the compressor controller need to be connected with the stator component, if the 3 leads have no guide piece, the 3 leads are disordered, and under the condition that the compressor frequently vibrates, the leads of the controller are easy to be connected and disconnected, so that the continuous operation of the compressor is affected.

For this purpose we propose a lower support module for the compressor rotating assembly.
