Abstract
PURPOSE: To ease initial enclosure of a refrigerant as well as additional refrigerant impregnation after cooling adjustment in an electric appliance utilizing cooling effect in refrigerant evaporation, by installing in the appliance an open- and-shut-by thread valve for vacuum exhaust and refrigerant impregnation for a refrigerant circuit.
CONSTITUTION: In vacuum exhaustion accompanied by the turning of a valve cover as well as the opening of a valve seat 13a and a valve proper 15b, gas such as air in a airtight vessel 11 is through a gap between the valve seat 13a and valve proper 15b and also through a hole 15c. In refrigerant impregnation, a refrigerant poured from a pipe 16 passes through a hole 15c, a gap between the valve seat 13a and valve proper 15b, and through a hole 12, and finally reaches the vessel 11. At the completion of refrigerant impregnant, the coupling of threaded part 13c to threaded part 15a achieved by turning the valve cover 15 brings the valve seat 13a into close contact with valve proper 15b, keeping the vessel 11 airtight. At the completion of cooling adjustment the permanent airtight treatment can be achieved by welding the cover covering the whole valve, without damaging the exhaust and impregnation pipe.
