REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2023/125655
Kind Code:
A1
Abstract:
Provided is a refrigerator, capable of efficiently and alternately performing cooling of a refrigerating chamber and cooling of a freezing chamber by using an evaporator. Provided is a refrigerator, comprising: a refrigerating chamber and a freezing chamber arranged in the refrigerator; a cooling circuit provided with a compressor and an evaporator; a fan for enabling gas in the refrigerator to flow; a refrigerating chamber opening and closing part used for opening and closing between a cooling flow path provided with the evaporator and the refrigerating chamber; a freezing chamber opening and closing part used for opening and closing between the cooling flow path and the freezing chamber; and a control part for controlling the compressor, the fan, the refrigerating chamber opening and closing part, and the freezing chamber opening and closing part. The control part enables the compressor and the fan to operate, opens the refrigerating chamber opening and closing part to allow the gas to flow into the refrigerating chamber from the cooling flow path so as to implement a refrigerating chamber cooling cycle, and ends the refrigerating chamber cooling cycle by at least closing the refrigerating chamber opening and closing part, so that the gas passes through the evaporator by means of the flow caused by the fan. The control part enables the compressor and the fan to operate, opens the freezing chamber opening and closing part to allow the gas to flow into the freezing chamber from the cooling flow path so as to implement a freezing chamber cooling cycle, and ends the freezing chamber cooling cycle by at least closing the freezing chamber opening and closing part, so that the gas passes through the evaporator by means of the flow caused by the fan. The control part performs control by alternately performing the refrigerating chamber cooling cycle and the freezing chamber cooling cycle. The control part performs pressure equalization after the refrigerating chamber cooling cycle is ended and before the freezing chamber cooling cycle is started. By means of the pressure equalization, the compressor operates, the fan is stopped, and the refrigerating chamber opening and closing part and the freezing chamber opening and closing part are closed.
