Refrigerator

Abstract

It is possible to provide a refrigerator which can suppress the temperature rise in the storage room and realize the freshness of food and the like. The refrigerator includes a storage compartment divided into at least a refrigerating compartment 3 and a freezing compartment 4, an evaporator 22 provided in a cooling chamber 8 connected to the storage compartment via the supply ducts 9 and 10, and a fan 13 for cooling the evaporator 22 Air is supplied from the cooling chamber 8 to the storage compartment, the duct opening and closing device 11 is inserted into the supply duct 10 connected to the refrigerating compartment 3, the second air duct opening and closing device 12 is inserted into the supply duct 9 connected to the freezing compartment 4, A second evaporator 23 provided inside or around the freezing compartment 4 and connected to the refrigerant passage B connected to the evaporator 22, and a switching unit 25 for switching whether or not the refrigerant flows to the evaporator 22 or the second evaporator 23. The refrigerator can suppress the temperature rise of the storage compartment and maintain the freshness of the food and the like at a high degree.

Description

technical field [0001] The invention relates to a refrigerator, which refrigerates and preserves food in a storage room, in particular to a refrigerator with a forced circulation evaporator and a direct cooling evaporator. Background technique [0002] Among the traditional refrigerators, there is a kind of refrigerator that forcibly circulates the air cooled by the evaporator in the storage room. For example, such a refrigerator is disclosed in the patent document JP-A-2013-200074. In this type of refrigerator, the evaporator is arranged inside the cooling chamber, and the air cooled in the evaporator is sent out of the cooling chamber by a fan, and supplied to the storage chamber through a supply air duct. The storage room is usually divided into a plurality of storage rooms such as a refrigerator room and a freezer room, and the amount of cold air supplied to each storage room is controlled by opening and closing a damper provided on the supply air duct.

Problems solved by technology

In addition, there is another problem that a large temperature change will cause the food to be thawed and then frozen, resulting in a large amount of ice inside the food, which will damage the food cells and cause the so-called drip.

In other words, it will lead to deterioration of the quality of food stored in the freezer
