Embodiment Construction

[0051] 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 casing 110, a device door 120, an ultrasonic generating module 190 and an ultrasonic vibrator. Specifically, the casing 110 defines a thawing chamber 111 for placing objects 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 . To facilitate the user to pick and place the objects to be processed, the thawing chamber 111 may have a top opening, that is, the pick-and-place opening of the thawing chamber 111 is set on the top side, and the device door 120 is set at the top opening. The ultrasonic generating module 190 is used for generating ultrasonic signals (generally referring to acoustic signals with a frequency higher than 20KHz). The ultrasonic generating module 190 is prefe...

Abstract

The invention provides an ultrasonic thawing control method and a refrigerator. The ultrasonic thawing control method includes the steps: an ultrasonic generating module generates an ultrasonic signal, and an ultrasonic oscillator generates corresponding ultrasonic waves to thaw a to-be-treated object according to the ultrasonic signal; the surface temperature of the to-be-treated object is obtained; whether the surface temperature of the to-be-treated object is greater than or equal to a preset target temperature is judged; if the surface temperature of the to-be-treated object is greater than or equal to the preset target temperature, the to-be-treated object is thawed. The refrigerator judges whether the to-be-treated object is thawed by detecting the surface temperature of the to-be-treated object, accurately controls the degree of thawing of the to-be-treated object, does not need a user to manually control to finish the thawing procedure, thereby improving the convenience of theuser.

Description

technical field [0001] The invention relates to the field of food thawing, in particular to an ultrasonic thawing control method and a refrigerator. Background technique [0002] Food cryopreservation is an efficient food preservation method, which can maintain high-quality food quality without polluting food, and is widely used in daily life. However, Chinese families generally require thawing to an easy-to-cut state (about -5°C) when cooking. How to make the temperature of the food to be thawed quickly and evenly rise from a frozen state (about-18°C) to an easy-to-cut state has always been a problem for people. issues of widespread concern. [0003] However, in the prior art, the thawing of air thawing and water thawing takes a long time, is easily contaminated by microorganisms and bacteria, loses more nutrients, has a large temperature difference between inside and outside, and is difficult to control the progress of thawing; heating wires and heating tubes thaw quickly...
