Abstract

The invention provides an unfreezing control method based on temperature, an unfreezing device and a refrigerator. The unfreezing control method based on the temperature comprises the steps that unfreezing cavity temperature field distribution detected by infrared temperature sensing equipment of the unfreezing device is continuously obtained, and a temperature sensing area of the infrared temperature sensing equipment is divided into a preset number of grids in advance; the temperature value of each grid is determined according to the temperature field distribution; according to the temperature value of the grid, the grid where an unfrozen object is located in the unfreezing device is determined; the unfreezing device is controlled to start unfreezing, and the unfreezing temperature of the unfrozen object is determined according to the temperature value of the grid where the unfrozen object is located in the unfreezing process; and after the unfreezing temperature is greater than a preset temperature threshold value, the unfreezing device is controlled to stop unfreezing. By means of the method, the temperature value reflecting an actual state of the unfrozen object can be accurately obtained, an accurate basis is provided for the unfreezing device to judge whether unfreezing is completed, insufficient unfreezing or excessive unfreezing can be effectively avoided, and the unfreezing quality is improved.

Description

technical field

[0001] The invention relates to household appliances, in particular to a temperature-based thawing control method, a thawing device and a refrigerator. Background technique

[0002] Frozen food needs to be thawed before processing or eating. The traditional thawing method generally uses a heating device to heat the frozen food. However, the thawing process of the heating device is prone to overheating, which affects the subsequent processing of the food and even causes the loss of food nutrition.

[0003] Devices dedicated to thawing have gradually appeared in the prior art, such as thawing through radio frequency and microwave techniques. These thawing devices are improved for heating methods, but most of the thawing control methods are still adjusted according to time, such as timing to end thawing. Although some thawing devices can also set the thawing time according to the weight of the thawing object, or adjust the thawing power according to the thawin...

Embodiment Construction

[0029] figure 1 is a schematic structural diagram of a thawing device 200 according to an embodiment of the present invention. figure 2 is a schematic block diagram of a thawing device 200 according to an embodiment of the present invention. The thawing device 200 of this embodiment may generally include: a casing 201 , an infrared temperature sensing device 210 , and a control device 220 . A thawing cavity 202 is formed in the casing 201 for preventing thawed objects. In order to illustrate the internal structure, figure 1 The door body of the thawing device 200 is not shown in the figure. The thawing device 200 can thaw the thawed objects put into the thawing cavity 202 by means of radio frequency thawing, microwave thawing, and heating thawing. For example, radio-frequency thawing can be achieved by arranging radio-frequency plates in the thawing chamber 202 , and using the radio-frequency plates to output radio-frequency signals to achieve thawing; and for example, mi...
