[0057] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0058] Example 1

[0059] The present embodiment provides a thawing control method, which is applied to a thawing device, which can be a device specifically used for thawing, or a device with a refrigeration function (such as a refrigerator). The thawing device includes at least two thawing spaces for thawing different types of food. The at least two thawing spaces are independent of each other. Exemplarily, the at least two thawing spaces include: a meat thawing space, a seafood thawing space, and a rice and flour thawing space. Each thawing space is provided with a first thawing module and a second thawing module, and the thawing principle of the second thawing module is different from that of the first thawing module.

[0060] Figure 1 is a flow chart of the thawing control method provided by an embodiment of the present invention, such as Figure 1 As shown, the method includes the following steps:

[0061] S101, after the food is placed in the thawing space, the quality of the food is tested.

[0062] S102: determining a target opening time of the first thawing module and an initial value of an operating parameter of the second thawing module according to the type and quality of the food.

[0063] S103, starting the first defrosting module, and after the target start-up time is reached, starting the second defrosting module according to the initial value of the operating parameter;

[0064] S104: detecting the electrical impedance value of the food, and adjusting the operating parameters of the second thawing module according to the change of the electrical impedance value.

[0065] Different thawing spaces correspond to different categories of food. When food is placed in any thawing space, the category of the food has been determined. In the above steps, when food is placed in a thawing space, the first thawing module and the second thawing module of the thawing space are subsequently controlled to thaw the food in the thawing space.

[0066] In this embodiment, thawing is performed by cooperating with a first thawing module and a second thawing module. The first thawing module can use a thawing method that quickly destroys ice crystal structures, while the second thawing module can use a thawing method that improves thawing uniformity. Specifically, suitable thawing methods can be selected from ultrasonic thawing, microwave thawing, radio frequency thawing, infrared thawing, and electrostatic field thawing. For example, the first thawing module can use ultrasonic thawing, while the second thawing method can use infrared thawing. Alternatively, the first thawing module can use microwave thawing, while the second thawing method can use electrostatic field thawing, etc.

[0067] The aforementioned operating parameters are parameters that can alter the thawing intensity of the second thawing module. Thawing intensity refers to the rate of change of the temperature of the thawed material per unit time during the thawing process. Operating parameters can include power, frequency, and / or voltage, among others. Different thawing methods correspond to different operating parameters. For example, infrared thawing, ultrasonic thawing, microwave thawing, and radio frequency thawing correspond to power, while electrostatic field thawing corresponds to voltage. Adjusting the value of the operating parameter can change the thawing intensity. Within the same timeframe, a higher operating parameter value results in a greater thawing intensity. In this embodiment, the first thawing module operates according to a fixed operating parameter value, while the operating parameter value of the second thawing module is adjustable.

[0068] Biological tissues are composed of cells, intercellular matrix, etc., and both intracellular and extracellular fluids contain various ions. These ions will move in a certain direction under the action of an electric field, forming an electric current. Because the cell membrane has capacitance characteristics and the intracellular and extracellular fluids have resistance characteristics, the biological tissue as a whole exhibits electrical impedance characteristics. When the water in the cells of the food freezes, it forms ice crystals, which causes changes in the cell structure and the distribution of ions inside and outside the cells. During the thawing process, the ice crystals melt, the ions are redistributed, and the electrical impedance value of the food changes accordingly. Therefore, the electrical impedance value of the food can reflect the degree of thawing of the food. The thawing progress of the food can be judged based on the changes in the electrical impedance value of the food during the thawing process, and the operating parameter value of the second thawing module can be adjusted accordingly, thereby achieving precise control of thawing, avoiding incomplete thawing or excessive thawing, and improving thawing efficiency.

[0069] This embodiment provides multiple independent thawing spaces, which can carry out targeted thawing of different types of food, support thawing of different types of food in a dedicated environment, prevent odor contamination, and facilitate precise control of thawing; the operation of the first thawing module and the second thawing module is controlled based on the type, quality, and change in electrical impedance value of the food. The first thawing module first quickly destroys the ice crystal structure in the food, and then the second thawing module finely and evenly thaws. Through the coordinated control of the first thawing module and the second thawing module, the thawing of the food can be accelerated, the thawing efficiency and thawing uniformity can be improved, and rapid thawing can be achieved to meet the urgent needs of users; based on the change in the electrical impedance value of the food during the thawing process, the thawing state inside the food can be accurately known, and then the thawing progress of the food can be accurately judged, and the operating parameter value of the second thawing module can be adjusted accordingly, the thawing process can be controlled in time, and precise control of thawing can be achieved, incomplete thawing or excessive thawing can be avoided, and thawing efficiency is improved; the problems of low thawing efficiency, inaccurate thawing control and easy odor contamination of food in the prior art are solved.

[0070] In an optional embodiment, the target on-time of the first thawing module and the initial value of the operating parameter of the second thawing module are determined according to the category and quality of the food, including: determining the interval in which the quality of the food is located; determining the target on-time and the initial value of the operating parameter corresponding to the category of the food and the interval according to pre-stored information, wherein, for any category of food, the larger the interval, the larger the target on-time and the initial value of the operating parameter corresponding to the interval.

[0071] This embodiment pre-divides the quality intervals and pre-stores the correspondence between different food categories, different quality intervals and target start-up time, and initial values ​​of operating parameters, so as to facilitate accurate thawing control according to the actual situation of the food during thawing.

[0072] In actual applications, for different categories of food, the quality intervals divided can be the same or different according to the characteristics of the food. For example, for meat, there are 4 quality intervals, and for seafood, there are 3 quality intervals.

[0073] In an optional embodiment, the operating parameters of the second thawing module are adjusted according to the change of the electrical impedance value, including: when the electrical impedance value of the food drops by a first value compared to its initial electrical impedance value, the operating parameters of the second thawing module are lowered; when the electrical impedance value of the food drops by a second value compared to its initial electrical impedance value, it indicates that the thawing is completed, and the first thawing module and the second thawing module are turned off to stop thawing; wherein the initial electrical impedance value is the electrical impedance value of the food detected when the second thawing module is turned on, and the first value is less than the second value.

[0074] The first value and the second value can be expressed as percentages. For example, when the electrical impedance value of the food drops to 80% of its initial impedance value, the operating parameters of the second thawing module are reduced. When the electrical impedance value of the food drops to 40% of its initial impedance value, the thawing is considered complete. In actual implementation, multiple values ​​can be set to control the reduction of the operating parameters of the second thawing module. For example, when the electrical impedance value of the food drops by a first value compared to its initial impedance value, the operating parameters of the second thawing module are reduced. When the electrical impedance value of the food drops by a third value compared to its initial impedance value, the operating parameters of the second thawing module are further reduced, and the first value < third value < second value.

[0075] In this embodiment, during the thawing process of food, the electrical impedance value of the food will decrease as the thawing progresses. The thawing progress is judged by the change in the electrical impedance value of the food. As the thawing progresses, the operating parameters of the second thawing module are appropriately reduced or the thawing is stopped. This can save energy, avoid excessive thawing, and achieve precise thawing control.

[0076] In an optional embodiment, when the actual on-time of the first thawing module reaches the target on-time, the method further includes: controlling the first thawing module to be intermittently on at a first time interval. The first time interval can be set according to actual conditions, for example, the first time interval is set to 10 minutes.

[0077] In the early stage of thawing, the food is in a frozen state, and the ice crystal structure is destroyed by the first thawing module. When the actual opening time of the first thawing module reaches the target opening time, the large ice crystals have been destroyed. The second thawing module is used as the main part to continue thawing, and the first thawing module is used as the auxiliary part. Therefore, the first thawing module is turned on intermittently and the duration of each opening during the intermittent opening process does not need to be too long, which assists the second thawing module in thawing work. While ensuring accurate thawing, it can also reduce energy waste.

[0078] Each defrosting space is provided with an air inlet for providing cold air to the defrosting space during the defrosting process. Taking a refrigerator as an example, the cold air inlet comes from the refrigerator's refrigeration.

[0079] After detecting the quality of the food, the method may further include determining a target air vent opening based on the food's quality, wherein the larger the food's quality range, the larger the target air vent opening. After reaching the target opening duration, the method may further include controlling the air inlet to the target air vent opening. Specifically, a correspondence between target air vent openings and different food categories and quality ranges may be pre-stored. During thawing, the target air vent opening appropriate for the food to be thawed is determined based on this pre-stored information. When thawing is complete, the air inlet of the thawing space is closed.

[0080] This embodiment takes into account that the second thawing module may cause the temperature of the food to rise. Therefore, the air inlet introduces cold air to prevent the food from overheating and affecting its quality, or even breeding microorganisms. The air inlet opening is accurately determined according to the quality of the food, avoiding excessive cold air affecting thawing or insufficient cold air resulting in poor results.

[0081] It should be noted that during the target opening time of the first thawing module, the ice crystal structure needs to be quickly destroyed to improve the thawing efficiency, and no cooling capacity needs to be introduced during this period.

[0082] The moisture content of rice and flour products themselves is relatively low, and the thawing of rice and flour products is mainly aimed at the frost or ice film that may exist on their surface. Therefore, targeted special thawing control can also be adopted for rice and flour products. Specifically, for the rice and flour thawing space, when it is detected that food is put into the rice and flour thawing space, the second thawing module of the rice and flour thawing space is opened according to the preset operating parameter value, and the air inlet of the rice and flour thawing space is opened according to the preset opening. After the first preset time, the second thawing module and the air inlet of the rice and flour thawing space are closed, and the thawing is completed.

[0083] If the pressure sensor in the rice and flour thawing space detects an increase in mass, it indicates that a rice and flour product has been placed in the rice and flour thawing space. The preset operating parameter value, preset opening, and first preset duration can all be set based on the characteristics of the rice and flour product and the actual situation of the thawing equipment. The preset operating parameter value and the preset opening cannot be the maximum value. For example, the preset operating parameter value is 50% of the maximum power, the preset opening is 50% of the maximum opening, and the first preset duration is set to 8 minutes.

[0084] This embodiment is for rice and flour products. The second thawing module is controlled to operate according to fixed operating parameters and the air inlet is controlled to have a fixed opening. The operation time is fixed to perform thawing. There is no need for the first thawing module to operate, which can reduce energy consumption. The preset operating parameter values ​​and the preset opening are not the maximum values, so excessive thawing will not occur. Even if the rice and flour products are not completely thawed, it will not have much impact on the user, and the product can still be directly processed and eaten.

[0085] After the food is thawed, there may be residual stains or juice in the thawing space. In order to prevent the growth of microorganisms, the thawing space can be sterilized. Specifically, after adjusting the operating parameters of the second thawing module according to the change in the electrical impedance value, it also includes: if the thawing is completed and it is detected that the food is taken out, the second thawing module is controlled to open for a second preset time to sterilize the thawing space.

[0086] Among them, most thawing methods have a sterilization effect. The second preset time is the time during which the second thawing module can effectively sterilize. The second preset time can be set according to actual conditions. For example, the second preset time is set to 1 minute.

[0087] In this embodiment, when thawing is completed and it is detected that the food is taken out, the second thawing module is controlled to sterilize the thawing space, which can prevent the growth of microorganisms and does not require an additional sterilization module, saving cost and space.

[0088] In an optional embodiment, the method may further include: controlling the second thawing module to operate for a second preset duration at a second time interval to sterilize the thawing space when no food is placed in the thawing space for thawing. The second time interval may be set based on actual conditions, for example, to 12 hours.

[0089] In this embodiment, when the user does not place food in the thawing zone for thawing, the second thawing module is controlled to sterilize the thawing zone, thereby providing a good thawing environment for thawing.

[0090] In actual application, a corresponding reminder sign can be set on the outside of each thawing space to inform the user of the category of ingredients that the thawing space is suitable for. For example, the outside of the meat thawing space is set with meat pictures, meat symbols or the word "meat", the outside of the seafood thawing space is set with seafood pictures, seafood symbols or the word "seafood", and the outside of the rice and flour thawing space is set with rice and flour pictures, rice and flour symbols or the word "rice and flour".

[0091] Of course, other methods can also be used to remind the user which thawing space to put the food to be thawed into. In an optional embodiment, before the food is put into the thawing space, it also includes: identifying the category of the food; outputting a first prompt information to prompt the user to the thawing space corresponding to the category of the food.

[0092] Specifically, the camera can capture images of the food to be thawed to automatically identify the food category. The first prompt information can be output through voice and / or indicator lights. For example, each thawing space is provided with its own indicator light. If meat food is identified, the indicator light of the thawing space corresponding to the meat food will light up, and the user will know to put the meat food in that thawing space. For another example, if seafood food is identified, a voice prompt will be output: Please put the seafood in the middle thawing space.

[0093] This embodiment can automatically identify the category of food to be thawed and prompt the user to the thawing space where the food should be placed, without the need for the user to identify it themselves, thereby facilitating user operation and improving user experience.

[0094] To facilitate the user's understanding of the thawing progress, while detecting the electrical impedance value of the food, the system further includes: determining the thawing progress based on changes in the electrical impedance value of the food; and synchronously outputting a second prompt message to indicate the thawing progress. The second prompt message can be output through voice and / or display, for example, in the form of a progress bar, or in the form of multiple progress lights. As the thawing progresses, the progress lights will light up one by one. When all the progress lights are fully lit, it indicates that the thawing is complete.

[0095] The correspondence between the change in the electrical impedance value of the food and the thawing progress can be pre-set. For example, for meat, when its electrical impedance value drops to 85% of the initial electrical impedance value, the corresponding thawing progress is 25%; when its electrical impedance value drops to 70% of the initial electrical impedance value, the corresponding thawing progress is 50%; when its electrical impedance value drops to 55% of the initial electrical impedance value, the corresponding thawing progress is 75%; when its electrical impedance value drops to 40% of the initial electrical impedance value, it is considered that the thawing is completed, and the corresponding thawing progress is 100%.

[0096] This embodiment can promptly remind the user of the thawing progress, making it easier for the user to know the thawing progress.

[0097] Taking into account that juice may flow out of the food during the thawing process, in an optional embodiment, each thawing space is provided with a juice collecting box for collecting the juice flowing out during the thawing process of the food. The juice collecting box is removable, for example, the juice collecting box is arranged in a drawer style. During the thawing process, the liquid level in the juice collecting box is detected; when the liquid level reaches a preset height, a third prompt message is output to remind the user to clean the juice collecting box. Specifically, a liquid level sensor can be provided in the juice collecting box to detect the liquid level in the juice collecting box. The preset height can be set according to the actual situation of the juice collecting box. The third prompt message can be output by voice and / or indicator light.

[0098] This embodiment can collect the juice flowing out during the thawing process of food in real time to prevent the food from being soaked, and can promptly remind the user to clean the juice collection box.

[0105] This embodiment provides multiple independent thawing spaces, which can carry out targeted thawing of different types of food, support thawing of different types of food in a dedicated environment, prevent odor contamination, and facilitate precise control of thawing; the operation of the first thawing module and the second thawing module is controlled based on the type, quality, and change in electrical impedance value of the food. The first thawing module first quickly destroys the ice crystal structure in the food, and then the second thawing module finely and evenly thaws. Through the coordinated control of the first thawing module and the second thawing module, the thawing of the food can be accelerated, the thawing efficiency and thawing uniformity can be improved, and rapid thawing can be achieved to meet the urgent needs of users; based on the change in the electrical impedance value of the food during the thawing process, the thawing state inside the food can be accurately known, and then the thawing progress of the food can be accurately judged, and the operating parameter value of the second thawing module can be adjusted accordingly, the thawing process can be controlled in time, and precise control of thawing can be achieved, incomplete thawing or excessive thawing can be avoided, and thawing efficiency is improved; the problems of low thawing efficiency, inaccurate thawing control and easy odor contamination of food in the prior art are solved.

[0106] The thawing equipment also includes:

[0107] a collection module, configured to collect images of food to be placed in the thawing space, and identify the category of the food based on the food images;

[0108] The prompt module is used to output first prompt information to prompt the user of the thawing space corresponding to the category of the food after identifying the category of the food, and output second prompt information to prompt the thawing progress during the thawing process.

[0109] The acquisition module may be a camera, specifically one acquisition module may be provided, or one acquisition module may be installed for each thawing space. The prompt module may be provided in a voice or display manner.

[0110] This embodiment can automatically identify the category of food to be thawed through the collection module, and can prompt the user to place the food in the thawing space through the prompt module, without the need for the user to identify it by himself, which is convenient for user operation. In addition, the prompt module can promptly remind the user of the thawing progress, thereby improving the user experience.

[0111] Each thawing space is equipped with a thawing table and a juice collection box. The thawing table is used to place ingredients to be thawed. The juice collection box is located below the thawing table and collects the juice that flows out during the thawing process. The thawing table is equipped with a filtrate tank, through which the juice flows into the juice collection box. The juice collection box is removable, for example, it is configured as a drawer.

[0112] In this embodiment, the juice collecting box can collect the juice flowing out during the thawing process of the food in real time to prevent the food from being soaked.

[0113] The juice box is equipped with a liquid level sensor for detecting the liquid level inside the juice box. When the liquid level reaches a preset level, a third prompt message is output to remind the user to clean the juice box. This embodiment uses the liquid level sensor to promptly remind the user to clean the juice box.

[0114] The pressure sensor is located on the upper surface of the thawing table and avoids the filter tank to facilitate the detection of food quality.

[0115] This embodiment does not limit the specific installation position of the bioimpedance sensor in the thawing space, as long as it can detect the electrical impedance value of the food in the thawing space. Preferably, the bioimpedance sensor is integrated with the pressure sensor.

[0116] Each thawing zone is provided with an air inlet for providing cold air to the thawing space during the thawing process, and the opening of the air inlet is controllable. In this embodiment, the air inlet introduces cold air during the thawing process, which can prevent the food from being overheated and affecting the quality of the food or even breeding microorganisms.

[0117] This embodiment does not limit the specific installation positions of the first thawing module and the second thawing module in the thawing space, as long as the food in the thawing space can be thawed normally.

[0118] Example 3

[0119] This embodiment illustrates the above-mentioned thawing device and thawing control method using a specific example. However, it should be noted that this specific example is only for the purpose of better illustrating the present application and does not constitute an undue limitation of the present application. Explanations of terms that are the same or corresponding to those in the above-mentioned embodiment will not be repeated in this embodiment.

[0120] like Figure 2 As shown in FIG, it is a schematic diagram of the thawing space. The thawing equipment includes three thawing spaces, namely: a meat thawing space 11, a seafood thawing space 12 and a rice and flour thawing space 13.

[0121] Each thawing space is provided with a first thawing module 21 and a second thawing module 22. The second thawing module 22 operates on a different thawing principle than the first thawing module 21. This embodiment does not limit the specific installation locations of the first thawing module 21 and the second thawing module 22 within the thawing space, as long as they can thaw the food in the thawing space normally.

[0122] This embodiment takes the first thawing module 21 using ultrasonic thawing and the second thawing module 22 using infrared thawing as an example.

[0123] The first thawing module 21 is embedded in the side walls of the thawing space. The side walls of the thawing space are made of metal to prevent energy leakage. Figure 4 The first thawing module 21 using ultrasonic thawing is mainly composed of a piezoelectric ceramic array. When voltage is applied to the piezoelectric ceramic array, it will deform and generate mechanical vibrations, thereby generating ultrasonic waves. The ultrasonic waves vibrate at a high frequency when the food is thawed, generating micron-sized bubbles at the ice-water interface. When the bubbles burst, shock waves are released, destroying the ice crystal structure, increasing heat transfer, and achieving efficient and rapid thawing.

[0124] The second thawing module 22, located at the top of the thawing chamber, uses infrared thawing with a graphene far-infrared heating film (adjustable from 0 to 100W). Graphene is combined with an electrically insulating substrate to form a 1-20μm, conductive film. When powered, it instantly stimulates interatomic resonance, releasing high-energy infrared radiation to warm and thaw the food within the thawing chamber. Ultrasonic waves disrupt the ice crystal structure, while infrared radiation produces uniform thermal radiation. The combined effect accelerates thawing.

[0125] Each thawing space is provided with a camera 23 for collecting images of food to be placed in the thawing space, so as to identify the category of the food based on the food image.

[0126] Each thawing space is provided with a juice collecting box 24 for collecting the juice flowing out during the thawing process of the food.

[0127] refer to Figures 3A to 3E Each thawing space is equipped with a thawing table 25 for placing food to be thawed. The thawing table 25 is provided with a filtrate tank 26. A juice collection box 24 is located below the thawing table 25. The juice flows through the filtrate tank 26 into the juice collection box 24. The juice collection box 24 is removable, for example, it is arranged in a drawer style.

[0128] A liquid level sensor 241 is provided in the juice collecting box 24 for detecting the liquid level in the juice collecting box 24. When the liquid level reaches a preset height, there is a risk of overflow, and the user is reminded to clean the juice collecting box.

[0129] Each thawing chamber is equipped with a sensing module 27, which integrates a pressure sensor and a bioimpedance sensor. When a user places food to be thawed into the thawing chamber, the pressure sensor detects the food's mass. During the thawing process, the bioimpedance sensor measures the food's electrical impedance in real time.

[0130] Each thawing space is provided with a function display module 28 for prompting the user which thawing space should be placed and the thawing progress. Figures 5A to 5C Each thawing space panel is equipped with an ingredient category indicator light. When the camera 23 captures an ingredient image and identifies the ingredient category, the ingredient category indicator light above the thawing space corresponding to that ingredient category lights up, instructing the user to place the ingredient in that thawing space. Each thawing space panel is also equipped with a progress light. As thawing progresses, the progress lights light up one by one. When all four progress lights are on, thawing is complete. Alternatively, as thawing progresses, the corresponding progress lights light up, and when the progress light indicating 100% lights up, thawing is complete.

[0131] Each thawing space is provided with an air inlet 29 for providing cooling to the thawing space during the thawing process. The opening of the air inlet 29 is controllable, for example, by adjusting the air inlet baffle 291. Specifically, the target air inlet opening and the target opening time of the first thawing module 21 can be determined based on the quality of the food to be thawed.

[0132] refer to Figure 6 , is a schematic diagram of the air inlet opening state. For example, when the weight of the food placed in the thawing space by the user is less than 500g, the target opening time of the first thawing module 21 is shorter and the target air inlet opening is smaller. That is, the damper 291 moves to open the air inlet 29 to state A. When the weight of the food placed in the thawing space by the user is between [500g, 1500g], the target opening time of the first thawing module 21 is slightly longer and the target air inlet opening is slightly larger. That is, the damper 291 moves to open the air inlet 29 to state B. When the weight of the food placed in the thawing space by the user is greater than 1500g, the target opening time of the first thawing module 21 is longer and the target air inlet opening is larger. That is, the damper 291 moves to open the air inlet 29 to state C. The air inlet opening in state C is greater than the air inlet opening in state B, which is greater than the air inlet opening in state A.

[0133] In this embodiment, the second thawing module 22 adopts infrared thawing. The principle of infrared thawing is mainly to utilize the thermal effect. The organic matter in the frozen food is composed of molecules and has a fixed vibration frequency. When the vibration frequency is consistent with the infrared vibration frequency, the molecules generate heat by resonance to achieve the purpose of thawing. This thawing method will be accompanied by an increase in temperature. Therefore, the air entering through the air inlet can not only make the food resonate for thawing, but also will not cause the temperature of the food to rise and cause the growth of microorganisms.

[0134] This embodiment mainly uses the coordinated control of two thawing methods to efficiently, quickly and accurately thaw the food placed in the thawing space of the refrigerator by the user. Figure 7 As shown, the thawing control includes the following steps:

[0135] S701, when the user does not place food in the thawing space, every time interval t6, the second thawing module 22 is controlled to open for t0, and the thawing space is sterilized to provide a good thawing environment for thawing.

[0136] In this embodiment, the second thawing module 22 adopts infrared thawing, which has a heating effect. When the microorganisms are irradiated by infrared rays, the water molecules in their bodies will absorb light energy and convert it into heat energy, causing the temperature in the microorganisms to rise rapidly, thereby destroying the cell walls and cell membranes of the microorganisms, causing them to lose their ability to survive, and playing a sterilization role.

[0137] S702, when the user needs to defrost the food, the camera 23 set above the thawing space collects images of the food to be thawed. After identifying the category of the food, the food category display light above the thawing space corresponding to the food category lights up to remind the user to place the food in the thawing space.

[0138] S703, the user places the food to be thawed on the thawing table, and the pressure sensor in the sensing module 27 detects the quality of the food, and determines the target opening time of the first thawing module 21, the initial value of the operating parameters of the second thawing module 22, and the target air inlet opening according to the type and quality of the food.

[0139] (1) Meat thawing space and seafood thawing space:

[0140] S704: When the food weight detected by the pressure sensor is less than 500g, the first thawing module 21 is controlled to be turned on for a period of time t1. After the period of time t1 expires, the first thawing module 21 is controlled to be turned on intermittently at intervals t2. At the same time, the second thawing module 22 is turned on at 50% of the maximum power (e.g., 100W), and the air inlet 29 is controlled to be in state A. The bioimpedance sensor in the sensing module 27 detects the electrical impedance value of the food in real time. When the electrical impedance value of the food drops to 80% of its initial electrical impedance value, the second thawing module 22 is controlled to be reduced to 25% of the maximum power and then continue thawing. The air inlet 29 remains in state A. When the electrical impedance value of the food drops to 40% of its initial electrical impedance value, thawing is considered complete, and the first thawing module 21, the second thawing module 22, and the air inlet 29 are closed, and thawing stops. During the thawing process, the thawing progress is displayed in a timely manner according to the electrical impedance value of the food.

[0141] S705: When the food weight detected by the pressure sensor is [500g, 1500g], the first thawing module 21 is controlled to be turned on for a duration of t3. After the duration of t3, the first thawing module 21 is controlled to be turned on intermittently at intervals of t2. At the same time, the second thawing module 22 is turned on at 75% of the maximum power (e.g., 100W), and the air inlet 29 is controlled to be in state B. The bioimpedance sensor in the sensing module 27 detects the electrical impedance value of the food in real time. When the electrical impedance value of the food drops to 80% of its initial impedance value, the second thawing module 22 is controlled to be reduced to 50% of the maximum power and then continue thawing. The air inlet 29 remains in state B. When the electrical impedance value of the food drops to 40% of its initial impedance value, thawing is considered complete, and the first thawing module 21, the second thawing module 22, and the air inlet 29 are closed, and thawing stops. During the thawing process, the thawing progress is displayed in a timely manner according to the electrical impedance value of the food.

[0142] S706: When the food weight detected by the pressure sensor is greater than 1500g, the first thawing module 21 is controlled to be turned on for a duration of t4. After the duration of t4, the first thawing module 21 is controlled to be turned on intermittently at intervals of t2. At the same time, the second thawing module 22 is turned on at maximum power (100W), and the air inlet 29 is controlled to be in state C. The bioimpedance sensor in the sensing module 27 detects the electrical impedance value of the food in real time. When the electrical impedance value of the food drops to 80% of its initial impedance value, the second thawing module 22 is controlled to be reduced to 75% of its maximum power and then continue thawing. The air inlet 29 remains in state C. When the electrical impedance value of the food drops to 40% of its initial impedance value, thawing is considered complete, and the first thawing module 21, the second thawing module 22, and the air inlet 29 are closed, and thawing stops. During the thawing process, the thawing progress is displayed in a timely manner according to the electrical impedance value of the food.

[0143] It should be noted that, in actual applications, for meat and seafood in the same quality range, the target on-time of the two can be the same or different, and the initial values ​​of the operating parameters of the two can be the same or different.

[0144] (2) Rice and flour thawing space:

[0145] S707, when the pressure sensor in the rice and flour thawing space detects a weight change ΔG>0, it means that food is put into the rice and flour thawing space, and the second thawing module 22 is controlled to open at 50% of the maximum power, and the air inlet 29 is controlled to be in state B. After t5 time, it is considered that the thawing is completed, and the second thawing module 22 and the air inlet 29 are closed to stop thawing.

[0146] S708, when the food is thawed and the user takes out the food, there may be residual stains or juice on the thawing table. To prevent the growth of microorganisms, the second thawing module 22 is controlled to be turned on for a time t0 to sterilize the thawing space.

[0147] t6>t4>t3>t2>t5>t1>t0, illustratively, t6=12h, t4=20min, t3=15min, t2=10min, t5=8min, t1=5min, t0=1min.
