Separated type liquid level sensor and compressor with liquid level sensor

Abstract

The invention discloses a separated type liquid level sensor and a compressor with the liquid level sensor. A terminal part and a sensor part of the liquid level sensor can be separated. So, when the compressor is assembled, on a state that a stator is installed on a main body housing, on which the terminal part is installed in advance, in a heat pressing fit manner, the senor part is fastened to the terminal part, the separated type liquid level sensor can be easy to install, and the liquid level sensor can be installed at a position where the liquid level sensor is overlapped with an auxiliary bearing. So the length of a lower part cover does not need to be lengthened, the length of a crank shaft shortens corresponding, the overall length of the compressor shortens with shortening of the crank shaft, material cost can be reduced, vibration noises of the compressor can be decreased, and a filling amount of an oil can also be reduced.

Description

technical field [0001] The invention relates to a separate liquid level sensor arranged inside a compressor for detecting oil quantity and a compressor with the liquid level sensor. Background technique [0002] Usually, a compressor has both a motor mechanism unit for generating a driving force and a compression mechanism unit receiving the driving force of the motor mechanism unit to compress gas in a closed housing internal space. [0003] The housing of the hermetic compressor is filled with a specified amount of oil for lubricating the compression mechanism or cooling the motor mechanism, and a part of the oil is used to participate in the refrigeration cycle through the compression mechanism to adjust to a constant Maintain prescribed amount. [0004] However, recently, the structure of the compressor has become more complex and larger, and the length of the piping has also become longer. As a result, part of the oil discharged from the compressor remains in the long ...

Problems solved by technology

[0015] As described above, in the conventional scroll compressor, the integrated liquid level sensor 80 is combined with the lower cover 13 on the lower side of the auxiliary bearing 70, but in this case, the crankshaft 30 and the lower cover The length of 13 becomes longer, so there is a problem that the material cost becomes higher and the vibration noise of the compressor becomes larger
