Abstract

To provide a compressor capable of detecting capacitance and measuring the quantity of a refrigerator oil with a low cost and simple configuration. A compressor of the present invention is provided with: an airtight container; a compressing mechanism unit that compresses a refrigerant gas in the airtight container; one connecting terminal, which is provided to penetrate the airtight container fromthe inside to the outside, and which is electrically insulated from the airtight container; and one electrode, which is electrically and mechanically connected to the connecting terminal in the airtight container, and which is disposed by having an electrode surface face the inner surface of the airtight container, said one electrode generating capacitance between the electrode surface and the inner surface of the airtight container.

Description

technical field [0001] The present invention relates to a compressor used in the refrigerating cycle of refrigerating and air-conditioning devices such as air conditioners and refrigerators to compress refrigerant gas. Background technique [0002] Generally, a compressor that compresses a refrigerant gas is used in a refrigeration cycle of a refrigeration air-conditioning device such as an air conditioner or a refrigerator. In order to operate the compressor, it is necessary to supply enough refrigerating machine oil to the compression mechanism portion that compresses the refrigerant to ensure a good lubricating state. For the compressor, if sufficient refrigerating machine oil is not supplied to the compression mechanism, the gaps between the various parts of the compression mechanism and the bearings will not be completely sealed, and the refrigerant gas will leak from the compression chamber, resulting in a decrease in the cooling capacity of the refrigeration and air c...
