Title:
HERMETIC COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2024/111193
Kind Code:
A1
Abstract:
A hermetic compressor according to the present invention is provided with: a compression mechanism unit 10 that compresses a refrigerant; an electric mechanism unit 20 that drives the compression mechanism unit 10; and a hermetic container 1 that accommodates the compression mechanism unit 10 and the electric mechanism unit 20. At an inner bottom of the hermetic container 1, an oil reservoir unit 4 is formed. On the outer periphery of the electric mechanism unit 20, a spacer 21 fixed to both the electric mechanism unit 20 and the hermetic container 1 is provided. Thus, in a compressor using an HC refrigerant and an HFO refrigerant, both securement of freezing ability and heating ability and a reduction in motor cost are achieved by securement of excluded volume and miniaturization of a motor, and also a reduction in an amount of oil ejected to the outside of the compressor is achieved.
