Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a box body, a refrigerating door body, a temperature-variable door body, a freezing door body and an unfreezing device. A refrigerating chamber, a temperature-variable chamber and a freezing chamber are defined in the box body. The refrigerating door body, the temperature-variable door body and the freezing door body are used for opening and closing a picking and placing opening of the refrigerating chamber, a picking and placing opening of the temperature-variable chamber and a picking and placing opening of the freezing chamber correspondingly. The unfreezing device comprises a barrel, a device door body, a radio frequency generation module and a radio frequency antenna. An unfreezing cavity used for containing a to-be-processed object is defined in the barrel. The device door body is used for opening and closing a picking and placing opening of the unfreezing cavity. The radio frequency antenna is electrically connected with the radio frequency generation module. The radio frequency antenna is configured to generate radio frequency waves with the corresponding frequency in the unfreezing cavity according to a radio frequency signal to unfreeze the to-be-processed object in the unfreezing cavity. The unfreezing device is arranged in the temperature-variable chamber. According to the refrigerator, the unfreezingdevice is arranged in the temperature-variable chamber; and compared with the manner of arranging the unfreezing device in the other chambers, the influence on the temperature of the storage space, outside the unfreezing device, in the chamber is small, and convenience of users is improved.

Description

technical field [0001] The invention relates to the field of thawing, in particular to a refrigerator with a thawing function. Background technique [0002] The freezer compartment of a general household refrigerator (the temperature of the freezer compartment is generally -18°C) is used to store food that will not be eaten in a short period of time, especially various meats. Before cooking the food stored in the freezer, the user usually Frozen ingredients need to be thawed to about -5°C. Meat at this temperature is easy to cut and will not be cut because the temperature is too low. If the temperature is too high, it is difficult to cut and the cut meat or sliced ​​meat will not be shaped. [0003] However, in the prior art, the air thawing operation is simple, but the thawing time is too long, the surface of the food is easily oxidized, and the juice loss is serious after thawing; the water thawing is not only time-consuming, but also bacteria and microorganisms are easy t...

Problems solved by technology

[0003] However, in the prior art, the air thawing operation is simple, but the thawing time is too long, the surface of the food is easily oxidized, and the juice loss is serious after thawing; the water thawing is not only time-consuming, but also bacteria and microorganisms are easy to grow on the surface of the food during the thawing process, seriously Affect food quality; heating wire or heating tube for thawing, the heating efficiency is low and the temperature of the food after thawing is uneven; when the microwave oven based on the magnetron technology thaws the food, the electromagnetic wave emitted by the magnetron as the emission source cannot be controlled The phase and poor directionality of the food will lead to uneven heating inside and outside the food, which will cause the temperature difference between the inside and outside of the thawed food to be too large, the juice will be lost too much, and the quality of the food will be seriously damaged.
