Embodiment Construction

[0053] 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 dev...

Abstract

This invention provides a control method for a thawing device. The control method includes the steps that a radio frequency generator module generates radio frequency signals; a radio frequency antenna generates radio frequency waves of the corresponding frequency in a thawing chamber according to the radio frequency signals and enables a to-be-treated object to thaw; the surface temperature of the to-be-treated object is obtained; if the surface temperature of the untreated object is greater than or equal to a preset target temperature, the radio frequency generator module stops working. By adopting the thawing device in this invention, users only need to turn on a thawing switch to start the thawing procedure, and the thawing device can automatically terminate the thawing procedure whenthe thawing is completed without the users' manual control, thus improving the user's convenience.

Description

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