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°

Embodiment approach

[0041] In addition, as another embodiment of the present invention, when the first refrigeration assembly 31 uses the direct cooling method to respectively cool the low-temperature chamber 13 and the variable temperature chamber 14, similar to the above-mentioned control and refrigeration methods in this embodiment, it also It can be realized that only the first refrigeration system 3 is used for refrigeration when the ultra-low temperature cryogenic function is not needed, and the low-temperature chamber 13 is used as an ordinary freezer or variable temperature chamber; when ultra-low temperature refrigeration is required, the first refrigeration system 3 is started at the same time The second refrigeration system 4 enables the semiconductor refrigeration module 41 to cool the low-temperature chamber 13 at the same time, thereby realizing the ultra-low temperature refrigeration function of the low-temperature chamber 13 .

[0042] In addition, in the above-mentioned embodiment...

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...
