Abstract
Description
Technical Field
[0001] This invention relates to the field of food processing, and in particular to a heating device with a water receiving box. Background Technology
[0002] During the freezing process, the quality of food is preserved; however, frozen food needs to be thawed before processing or consumption. To improve thawing efficiency and ensure thawing quality, electromagnetic wave heating devices are typically used to thaw food.
[0003] However, defrosting water and / or juices are produced during the thawing process, especially when the food is not completely sealed during freezing. An ice crystal layer forms on the outer surface of the food, which melts into liquid during thawing. This not only contaminates the heating chamber environment and is difficult to clean, but also exacerbates the temperature difference between the localized area and other parts of the food when partially immersed in the liquid, deteriorating the food quality and affecting the user's subsequent handling.

[0105] The preset frequency modulation condition can be that the electromagnetic wave generation module 710 has not adjusted the frequency of the electromagnetic wave signal it generates for a continuous preset time, or that the reflection parameter of the electromagnetic wave generation system is greater than the preset frequency modulation reflection threshold, so that the object to be processed 900 has a strong absorption capacity for electromagnetic waves during the heating process.
[0106] The reflection parameter can be the return loss S11. The reflection parameter can also be the reflected power value of the electromagnetic wave signal reflected back to the electromagnetic wave generation module 710.
[0107] The preset matching conditions can be the inflection point where the reflection parameters of the electromagnetic wave generating system show a dip or the reflection parameters are at their minimum value.
[0108] Under the condition of meeting the preset frequency modulation conditions, the processing unit can be configured to control the electromagnetic wave generation module 710 to adjust the frequency of the electromagnetic wave signal from the current frequency to the lower frequency direction, so as to shorten the frequency matching time and avoid undesirable energy waste.
[0109] In some embodiments, the processing unit may be configured to control the electromagnetic wave generating module 710 to stop working when any of the heating termination conditions are met, so as to ensure that the heating is terminated in a timely manner, so that the heating of the object to be processed 900 is accurately stopped at the state desired by the user, especially in the case of thawing, which facilitates the user to cut and process the object and avoids the generation of liquid, thereby reducing the volume of the water receiving box 400.
[0110] Specifically, the heating termination conditions may include at least two of the following conditions: the remaining heating time countdown is completed; the cumulative frequency difference Δf of the frequencies that meet the preset matching conditions for the preset number of times is less than the termination frequency difference threshold; the electromagnetic wave generating module 710 continues heating for the preset time when the frequency of the electromagnetic wave is the minimum value of the preset candidate frequency range; and the reflection parameter of the electromagnetic wave generating module 710 is greater than the preset termination reflection threshold when the frequency of the electromagnetic wave is the minimum value of the preset candidate frequency range, so as to determine whether the heating is completed from multiple perspectives such as time, physical state change, and moisture content.
