refrigerator

Abstract

The invention provides a refrigerator which comprises a refrigerator body, a first refrigerating system and a second refrigerating system, wherein the refrigerator body is provided with a freezing chamber and / or a temperature varying chamber and a low temperature chamber not communicated with the freezing chamber and / or the temperature varying chamber; the first refrigerating system comprises a first refrigerating component for providing cold quantity for the low temperature chamber by adopting a direct cooling or air cooling refrigerating way; the second refrigerating system is provided with a semiconductor refrigerating module arranged on the peripheral wall of the low temperature chamber. The cold end of the semiconductor refrigerating module is arranged in the low temperature chamber, and the hot end of the semiconductor refrigerating module is arranged outside the peripheral wall.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with a low-temperature chamber to obtain ultra-low temperature refrigeration effect. Background technique [0002] As a container that can keep food or other items in a constant low temperature and cold state, a refrigerator has become one of the indispensable household appliances in modern families. Wherein the refrigerator usually includes a refrigerating chamber and a freezing chamber which are arranged separately up and down, so as to separately store articles to be preserved at different temperatures. However, with people's pursuit of health and higher requirements for storage in refrigerators, some special ingredients, such as ultra-low temperature tuna, require ultra-low temperature storage, and the temperature of ordinary freezers can no longer meet users' requirements for low temperature. At present, there are some low-temperature freezers on the market that can meet the...

Problems solved by technology

But because this kind of refrigerator adopts evaporative refrigeration, the evaporation temperature of the evaporator 1 can only reach about -40°C at the lowest, and the refrigeration temperature of the quick-freezing drawer 20 can only reach about -35°C. The flocculation point of the refrigerator is around -48°C. In order to ensure the service life of the compressor, the refrigerator cannot be operated below the evaporation temperature of -40°C for a long time.

It can be seen that although this type of refrigerator can reduce food to -35°C in a short period of time, it cannot store it at low temperature for a long time.
