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.

Embodiment Construction

[0048] figure 1 is a schematic cross-sectional view of a thawing device 100 according to an embodiment of the present invention. see figure 1 , the thawing device 100 may include a cylinder body 110 , a device door 120 , a radio frequency generating module 190 and a radio frequency antenna 130 . Specifically, the barrel 110 defines a thawing chamber 111 for placing the object to be processed. The device door 120 can be arranged at the access opening of the thawing chamber 111 for opening and closing the access opening of the thawing chamber 111 . The radio frequency generating module 190 can be configured to generate radio frequency signals (generally refer to radio frequency signals with a frequency of 300KHz-300GHz). The radio frequency antenna 130 can be a rectangular metal sheet. The radio frequency antenna 130 may be composed of a transmitting antenna and a receiving antenna arranged side by side along the lateral direction or front-to-back direction of the thawing de...

Abstract

The invention provides an unfreezing control device for a refrigerator. The refrigerator comprises a box body for limiting at least one storing space, chamber doors for opening and closing an access port of at least one storing space, an unfreezing device and a progress display area, wherein the unfreezing device comprises a barrel body for limiting an unfreezing chamber, a door for opening and closing the access port, a radio frequency generating module, radio frequency antennas which are electrically connected to the radio frequency generating module, and a temperature sensor for sensing thesurface temperature of an object to be treated in the unfreezing chamber. The unfreezing control method comprises the steps of obtaining the current surface temperature of the object to be treated; determining the unfreezing progress of the object to be treated based on the current surface temperature of the object to be treated and the preset target temperature; and displaying the unfreezing progress of the object to be treated in the progress display are. According to the method, the display area is formed in a door body of the refrigerator, so that a user can directly know the unfreezing progress of the object to be treated in the unfreezing chamber, and as a result, the user can conveniently use the unfreezing performance.

Description

technical field [0001] The invention relates to the field of thawing, in particular to a thawing control method for a refrigerator. 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 e...
