Embodiment Construction

[0017] The present invention is specifically described below in conjunction with accompanying drawing:

[0018] combine Figure 1 to Figure 5 , a refrigerator with a deep freezing zone, comprising a first freezing zone 1 , a second freezing zone 2 and a refrigerating zone 3 .

[0019] The first freezing zone 1 is a cryogenic quick-freezing zone, and the lowest temperature in the first freezing zone 1 is less than or equal to -40°C.

[0020] Such as figure 1 As shown, taking a four-door refrigerator as an example, the left side of the freezing zone of the refrigerator is the first freezing zone 1 . Of course, other regions can also be selected as the first freezing region 1 .

[0021] Such as Figure 4 As shown, the first refrigeration zone 1 is equipped with a first refrigeration system 4, the first refrigeration system 4 includes a first compressor 41, the first compressor 41 is connected with a first condenser 42, and the first condenser 42 is connected with a first Dry...

Abstract

The invention provides a refrigerator with a deep-cooling quick-freezing zone, comprising a first freezing zone, a second freezing zone and a refrigerating zone, a first refrigeration system is arranged in the first freezing zone, and the first refrigeration system includes a first compressor, The first compressor is connected with the first condenser, the first condenser is connected with the first drying filter, the first drying filter is connected with the first freezing evaporator through the first capillary tube, the first freezing evaporator and the first compressor The first refrigeration system that is connected to form a cycle. A second refrigerating system is arranged in the second freezing zone, and both the second freezing zone and the refrigerating zone are matched with the second refrigerating system. R290 refrigerant is used in the first refrigeration system of the cryogenic and quick-freezing zone, and the first compressor is a high-efficiency compressor, so that the lowest temperature in the deep-freezing and quick-freezing zone can be less than or equal to -40°C, which can meet the rapid freezing of a large amount of food. The refrigerator satisfies various low-temperature requirements for family food preservation by separately setting a deep-freezing quick-freezing zone.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator with a deep-cooling quick-freezing compartment. Background technique [0002] Most of the household refrigerators on the market today have a four-star freezer design, that is, the lowest temperature in the freezer compartment of the refrigerator is -24°C, which can basically meet the freezing needs of food. However, as the user's frozen food storage cycle increases and the variety increases (such as tuna, ice cream), or the user puts in a large amount of food at one time, the food needs to be frozen quickly. In these cases, the refrigeration system requires a lower freezing temperature and faster cooling. Freezing speed, however, the current refrigeration system cannot meet the above demands. The cooling rate in the freezer compartment of the existing refrigerator is relatively slow, which will affect the freshness of the food. When the whole machine is turned on for ...
