Problems solved by technology

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] In the prior art, equipment dedicated to thawing has gradually appeared, such as thawing by radio frequency and microwave technology. However, due to the inaccurate detection of the temperature of the thawed object, the above-mentioned thawing equipment cannot guarantee accurate control of the thawing process, thus Insufficient defrosting or excessive defrosting occurs
Therefore lack in the prior art the means that the temperature of the thawed object is accurately detected

Embodiment Construction

[0030] 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 drawing. 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, m...

Abstract

The invention provides a temperature detection method for an unfrozen object, an unfreezing device and a refrigerator. The temperature detection method for the unfrozen object comprises the steps that infrared temperature sensing equipment of the unfreezing device is started, the infrared temperature sensing equipment is configured to detect temperature field distribution of an unfreezing cavity of the unfreezing device, and a temperature sensing area of the infrared temperature sensing equipment is divided into a preset number of grids in advance; a detection result of the infrared temperature sensing equipment is obtained, and a temperature value of each grid is determined according to the detection result; and the grid where the unfrozen object is located in the unfreezing device is determined according to the temperature value of the grid, and the detection temperature of the unfrozen object is calculated according to the temperature value of the grid where the unfrozen object is located. According to the method, the temperature value reflecting an actual state of the unfrozen object can be accurately obtained, detection is accurate, and an accurate basis is provided for unfreezing control of a subsequent unfreezing device.

Description

technical field [0001] The invention relates to household appliances, in particular to a method for detecting the temperature of thawed objects, 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] In the prior art, equipment dedicated to thawing has gradually appeared, such as thawing by radio frequency and microwave technology. However, due to the inaccurate detection of the temperature of the thawed object, the above-mentioned thawing equipment cannot guarantee accurate control of the thawing process, thus Insufficient defrosting or excessive defrosting occurs. Therefore, there is a lack of means for accurately detecting the temperat...
