Split-type compressor and household appliance

Abstract

The invention discloses a split-type compressor and a household appliance. The split-type compressor comprises a driving module and a compressing module, the driving module is provided with an outputshaft for outputting power, the compressing module is provided with a independently-sealed shell, and a compressing air cylinder arranged in the shell, and the output shaft is connected with a rotating shaft of the compressing air cylinder through a non-contact coupling. The maintenance process of the split-type compressor is simplified to lower the maintenance difficulty, and the using safety andreliability are improved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a split compressor and a household appliance. Background technique [0002] At present, a compressor is a driven fluid machine that upgrades low-pressure gas to high-pressure gas. It is widely used in household appliances and industrial equipment, especially in household appliances such as refrigerators, air conditioners and heat pump water heaters. All are equipped with compressors. At present, conventional compressors are usually sealed with motors and cylinders installed in a shell, and the motor drives the cylinder through the transmission device to complete the compression action. However, the later maintenance is very troublesome and difficult to maintain, and the safety and reliability of use are relatively high. Difference.

AI Technical Summary

Problems solved by technology

At present, conventional compressors are usually sealed and installed with motors and cylinders in a shell, and the motor drives the cylinder through the transmission device to complete the compression action. However, the later maintenance is very troublesome and difficult to maintain, and the safety and reliability of use are relatively high. Difference

Chinese patent application No. 201710094258.6 discloses a split compressor, which sets the drive motor and the compression cylinder in two shells respectively. As can be seen from the figure, the above patent technology only uses two separate shells to install the motor and the compressor respectively. The cylinder, the motor shaft and the compression cylinder are rigidly connected to drive the compression cylinder to rotate. The connection between the drive motor and the compression cylinder still needs to be sealed, and the problem of sealed connection needs to be considered. In the later stage, when repairing and replacing the relevant components of the motor, it is still necessary to ensure maintenance The sealed connection between the rear drive motor and the compressed air cylinder is still difficult to maintain
