[0045] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0046] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0047] In the specification and claims of this application and the accompanying drawings, the terms "first," "second," "third," etc. are used to distinguish similar or similar objects or entities, and are not necessarily intended to limit a particular order or sequence, unless otherwise noted. It should be understood that the terms used in this manner are interchangeable under appropriate circumstances.

[0048] The terms "comprise," "comprises," and "having," and any variations thereof, are intended to cover but not exclude inclusion; for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0049] The term "module" refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and / or software code that is capable of performing the functionality associated with that element.

[0050] In one embodiment, the prior art generally uses natural thawing (i.e., thawing at room temperature or thawing in a refrigerated state) when thawing frozen food. However, if the item to be thawed is food, this thawing method will cause water-soluble vitamins (such as vitamins B and C) to dissolve, resulting in the loss of nutrients. It will also cause the cells of the item to be thawed to rupture, and the juice loss rate can be as high as 5% to 15% (data for beef), affecting the taste and flavor. If the item to be thawed is thawed using microwave technology, it will also cause uneven heating of the item to be thawed, resulting in excessively high local temperatures in the item to be thawed, thereby destroying the protein structure.

[0051] Based on the above content, in some embodiments, the present application provides a refrigerator, characterized in that the refrigerator includes: a refrigerator body; a thawing box, placed in the refrigerator body, for storing items to be thawed; two electrode plates, placed in the thawing box; a controller, for responding to a thawing instruction, energizing the two electrode plates to perform ohmic heating on the items to be thawed located between the two electrode plates to thaw the items to be thawed; in the process of thawing the items to be thawed, the power supply voltage and / or distance of the two electrode plates are adjusted according to the internal environmental information of the thawing box to adjust the thawing power.

[0052] It should be noted that, in the process of thawing the items to be thawed, the refrigerator provided in the present application applies an alternating current to the items to be thawed through two electrode plates, so as to utilize the resistance characteristics of the items to be thawed themselves to convert the current into heat energy, thereby achieving a rapid and uniform temperature increase from the inside of the items to be thawed, thereby achieving the operation of thawing the items to be thawed.

[0053] Optionally, in some embodiments, the refrigerator treats the thawed items as follows: Figure 1As shown, AC mains power is used to supply power to the refrigerator, and an inverter controller is provided to filter, stabilize, and rectify the AC mains power. Furthermore, the controller energizes the two electrode plates to ohmically heat the items between them, thereby thawing them. During the thawing process, the voltage and / or distance between the two electrode plates are adjusted based on the internal environment of the thawing chamber to adjust the thawing power.

[0054] Further explanation: In order to ensure that users can more conveniently place the items to be thawed inside the refrigerator in the thawing box for thawing operations when using the refrigerator, a certain area inside the refrigerator can be divided as a placement area for the thawing box, so that users can directly transfer the items to be thawed inside the refrigerator to the thawing box in the placement area, thereby improving the user's thawing operation experience.

[0055] In one embodiment of the present application, Figure 2 As shown, when the thawing box is placed inside the refrigerator body, a part of the area inside at least one storage drawer included in the refrigerator can be divided as a placement area for the thawing box, and the thawing box is set in the placement area of a storage drawer inside the refrigerator body, ensuring that the user can more conveniently transfer the items to be thawed to the thawing box.

[0056] In another embodiment of the present application, Figure 3 As shown, when the thawing box is placed inside the refrigerator box, a storage drawer of the refrigerator can be directly used as a placement area for the thawing box, so that the storage drawer originally set in the placement area can be replaced with the thawing box, ensuring that the thawing box has enough space to carry the items to be thawed.

[0057] In another embodiment of the present application, in order to prevent the storage space inside the refrigerator from being occupied and to ensure that the thawing box has enough space to carry the items to be thawed, an extension area can be set outside the refrigerator body, and the extension area can be used as a placement area for the thawing box, so as to ensure that the thawing box has enough space to carry the items to be thawed without affecting the storage space inside the refrigerator body.

[0058] It should be noted that the electrode plates include a positive electrode plate and a negative electrode plate. By placing the items to be thawed between the positive electrode plate and the negative electrode plate, ohmic thawing of the items to be thawed can be achieved. In addition, the sides of the electrode plates are provided with power contacts, and the grooves are also provided with power contacts corresponding to the electrode plates. After the electrode plates are placed in the grooves inside the thawing box, the power contacts on the sides of the electrode plates are in contact with the power contacts inside the grooves, thereby realizing the supply of power to the electrode plates.

[0059] Further explanation: when there is no thawing medium (such as water or other solutions) in the thawing box, the internal environmental information may include but is not limited to: the volume of the space inside the thawing box, the air temperature inside the thawing box, etc.; when there is a thawing medium (such as water or other solutions) in the thawing box, the internal environmental information may include but is not limited to: liquid temperature and liquid resistance, etc.

[0060] Therefore, during the thawing process of the items to be thawed, the thawing status of the items to be thawed at the current moment can be judged based on the internal environmental information of the thawing box, and the power supply voltage and / or distance of the two electrode plates can be adjusted according to the thawing status to adjust the thawing power.

[0061] In one embodiment of the present application, if the internal environmental information includes liquid temperature and liquid resistance, therefore, when adjusting the distance between the two electrode plates according to the internal environmental information of the thawing box to adjust the thawing power, it may include the following: adjusting the distance between the two electrode plates to the target distance corresponding to the current liquid resistance, and thawing the items to be thawed with the thawing power corresponding to the target distance; in the process of thawing the items to be thawed with the thawing power corresponding to the target distance, if it is detected that the liquid temperature does not fall within the ideal temperature range, the thawing power is adjusted to zero, and after detecting that the liquid temperature falls within the ideal temperature range, the thawing power is adjusted to the thawing power corresponding to the target distance corresponding to the current liquid resistance.

[0062] In another embodiment of the present application, if the internal environmental information includes liquid temperature and liquid resistance, therefore, when adjusting the power-on voltage of the two electrode plates according to the internal environmental information of the thawing box to adjust the thawing power, it may include the following: adjusting the power-on voltage of the two electrode plates to the target voltage corresponding to the current liquid resistance, and thawing the items to be thawed by the thawing power corresponding to the target voltage; in the process of thawing the items to be thawed by the thawing power corresponding to the target voltage, if it is detected that the liquid temperature does not fall within the ideal temperature range, the thawing power is adjusted to zero, and after detecting that the liquid temperature falls within the ideal temperature range, the thawing power is adjusted to the thawing power corresponding to the target voltage corresponding to the current liquid resistance.

[0063] In summary, by placing the thawing box inside the refrigerator box, it is convenient to directly thaw the items to be thawed inside the refrigerator, thereby achieving seamless compatibility between the thawing box and the refrigerator box; and, by energizing the two electrode plates, the items to be thawed located between the two electrode plates are ohmically heated, thereby ensuring that the items to be thawed can be ohmically thawed, thereby achieving rapid thawing of the items to be thawed, improving the thawing efficiency of the items to be thawed, and during the thawing process, the power-on voltage and / or distance of the two electrode plates are adjusted according to the internal environmental information of the thawing box, so that the items to be thawed can be in the optimal thawing state, thereby maximizing the guarantee that the quality of the items to be thawed will not be affected by the thawing operation, thereby achieving the guarantee of the quality of the items to be thawed while ensuring that the thawing efficiency of the items to be thawed is not affected.

[0064] In one embodiment, one or both of the two electrode plates are detachable electrode plates; a plurality of grooves are provided in the thawing box, and the grooves are at least used to place the detachable electrode plates so as to adjust the thawing power by changing the distance between the two electrode plates.

[0065] In one embodiment of the present application, the structure of the thawing box can be as follows: Figure 4 Figure 5 As shown, grooves are provided on both sides of the interior of the thawing box, and each groove is provided with a power contact to ensure that after the electrode plate is inserted into the groove, the power contacts inside the groove and the power contacts of the electrode plate can be connected to each other, so that after the main power interface outside the thawing box is connected to the power supply, the electrode plate can be supplied with electricity.

[0066] Among them, the power supply line for the electrode plate can be directly cast inside the material, making the connection between the electrode plate and the power supply contact invisible, or it can be placed on the outer surface of the thawing box, and a cover can be added to protect the exposed power supply line.

[0067] In one embodiment of the present application, Figure 6 As shown, a main power interface can also be set on the outside of the thawing box. By connecting the main power interface to the external power supply, the electrode plate can be supplied with electricity after the power contacts on the side of the electrode plate are in contact with the power contacts inside the groove.

[0068] In another embodiment of the present application, in order to better control the thawing efficiency of the items to be thawed, different thawing efficiencies are selected according to different thawing requirements, and different grooves provided in the thawing box can correspond to different thawing gears.

[0069] In one embodiment of the present application, Figure 7As shown, three grooves can be set in the thawing box, so that the positive electrode plate in the electrode plate is placed in the groove, and the negative electrode plate is fixed on one side of the thawing box, so that the two electrode plates are parallel to each other, and by adjusting the groove into which the positive electrode plate is inserted, the conditions for the thawing efficiency of the thawing equipment are achieved, wherein, by adjusting the groove into which the positive electrode plate is inserted, the interval between the positive electrode plate and the negative electrode plate is increased, and at this time the thawing gear of the thawing equipment is lower and the thawing efficiency is lower; by adjusting the groove into which the positive electrode plate is inserted, the interval between the positive electrode plate and the negative electrode plate is reduced, and at this time the thawing gear of the thawing equipment is higher and the thawing efficiency is greater.

[0070] In summary, the present application realizes that the thawing box carries the items to be thawed by the thawing box, ensuring that the items to be thawed can be effectively thawed, so that the items to be thawed can be in the best thawing position, and by placing the thawing device as a whole inside the refrigerator, it is convenient to directly thaw the items to be thawed in the refrigerator, thereby achieving seamless compatibility with the refrigerator. Furthermore, based on at least one groove for placing the electrode plate inside the thawing box, it is ensured that when the electrode plates are placed in different grooves, the thawing device can have different thawing efficiencies, achieving the effect of adaptively adjusting the thawing efficiency of the thawing device according to the different conditions of the items to be thawed, and achieving the quality preservation of the items to be thawed, preventing the items to be thawed from deteriorating due to excessively high thawing temperatures.

[0071] In one embodiment, an electric rail may be provided in the thawing box, and the electric rail is movably connected to the electrode plate; in this case, when the controller adjusts the distance between the two electrode plates according to the internal environmental information of the thawing box, it is configured to: control the rotation of the motor with the electric rail according to the internal environmental information of the thawing box to adjust the distance between the two electrode plates.

[0072] Among them, since the electric rail is movably connected to the electrode plate, when the electric rail rotates, stepless adjustment of the electrode plate can be achieved.

[0073] In one embodiment of the present application, in order to increase the stability of the electrode plate during the position adjustment process, a plurality of conductive rails may be provided to be threadedly connected to the electrode plate to prevent the electrode plate from tilting during the position adjustment process; specifically, Figure 8 As shown, the number of the conductive rails can be set to two, and the two conductive rails respectively pass through the two sides of the electrode plate and are movably connected to the electrode plate.

[0074] In another embodiment of the present application, Figure 9As shown, in order to further increase the movement stability of the electrode plate, the contact position between the electrode plate and the electrically conductive rail can be designed with a flange to increase the contact area between the electrode plate and the electrically conductive rail, further suppressing the angular tilt of the electrode plate during position adjustment.

[0075] In summary, the present application realizes stepless adjustment operation for the electrode plate by providing an electric guide rail, further improving the flexibility of adjusting the position of the electrode plate, and enabling the thawing equipment to perform more accurate and detailed thawing power adjustment.

[0076] In one embodiment, a needle-shaped electrode is provided on the side of the electrode plate facing the object to be thawed; as the distance between the two electrode plates decreases, the needle-shaped electrode gradually penetrates into the object to be thawed to thaw the object.

[0077] It should be noted that when thawing items to be thawed through electrode plates, if the volume of the items to be thawed is large, it is difficult to ensure uniform thawing of the interior and surface of the items to be thawed, which will cause uneven thawing of the items to be thawed, affecting the quality of the items to be thawed. For this reason, the position of the electrode plate can be adjusted so that the needle-shaped electrode on one side of the electrode plate can be slowly inserted into the interior of the items to be thawed as the electrode plate moves, thereby achieving fast and uniform thawing of the items to be thawed.

[0078] In one embodiment of the present application, a needle-shaped electrode structure is provided on one side of the positive electrode plate, or a needle-shaped electrode structure is provided on one side of the negative electrode plate. Figure 10 As shown, the side of the positive electrode plate provided with the needle-shaped electrode faces the side of the negative electrode plate provided with the needle-shaped electrode. Therefore, when both the positive electrode plate and the negative electrode plate are provided with needle-shaped electrodes, the structure is as follows: Figure 11 shown.

[0079] Among them, in order to improve the thawing efficiency, multiple needle-shaped electrodes are set on one side of the electrode plate. The number of needle-shaped electrodes is not limited here, and in order to ensure uniform thawing effect on the items to be thawed, the spacing distance between each needle-shaped electrode needs to be set to the same.

[0080] Further explanation: since the sizes of items to be thawed are different, in order to ensure that the needle-shaped electrode can meet the thawing needs of items to be thawed of different sizes, it can also include the following contents: the needle-shaped electrode includes a first needle tube and a retractable second needle tube; the first needle tube is fixedly connected to the electrode plate; there is a cavity inside the first needle tube, the second needle tube is arranged in the cavity of the first needle tube, and the second needle tube is retracted along the height direction of the first needle tube.

[0081] In one embodiment of the present application, Figure 12 As shown, the second needle tube is slidably disposed in the cavity of the first needle tube.

[0082] In one embodiment of the present application, Figure 13 As shown, the outer surface of the electrode plate is wrapped with a silicone layer.

[0083] In one embodiment of the present application, the material of the electrode plate is a conductive material, such as SUS304, SUS316, SUS316L, Al5052, platinum titanium, food-grade silicone, etc.; the material of the electrode plate is not limited here.

[0084] In one embodiment of the present application, the electrode plate is an elastic electrode plate made of a flexible material. Therefore, before the electrode plate is wrapped around the item to be thawed, Figure 14 As shown, the motor to be thawed is a planar structure; after the electrode plate wraps the item to be thawed, as shown Figure 15 and Figure 16 As shown, a more uniform thawing effect can be provided for the items to be thawed.

[0085] In one embodiment of the present application, the shape of the electrode plate is rectangular, circular, triangular or irregular. As an example, the irregular shape of the electrode plate can be as follows: Figure 17 As shown, the motor shape of the electrode plate is not limited here.

[0086] It should be noted that this application does not limit the power supply method of the thawing equipment. The connection line between the electrode plate and the power supply contact can be hidden inside the thawing box by casting, or it can be set outside the thawing box and protected by adding a cover.

[0087] In some embodiments, to further ensure uniform thawing of the items to be thawed, water (or other thawing solution) can be injected into the thawing box as a medium, and the items to be thawed are placed in the medium, so that the items to be thawed are ohmically thawed through pluggable electrode plates. In summary, the present application controls the electrode shape of the electrode plate so that the electrode plate can adapt to different items to be thawed, ensuring that even when thawing items of different sizes are thawed, the items to be thawed can still be uniformly thawed.

[0088] It should be noted that if the item to be thawed is meat, the meat is placed in the aqueous solution in the thawing chamber. As the ohmic thawing proceeds, the liquid temperature and liquid resistance of the water will continue to change. The meat will release ions into the water during the thawing process, and the neutral ions in the aqueous solution will increase, at which point the liquid resistance will decrease. Furthermore, as the thawing proceeds, the liquid temperature of the water will also increase. However, it should be noted that the water temperature must be controlled within a certain range during the thawing process. This ensures that the liquid temperature does not affect the nutritional value of the meat itself (too high a temperature will affect the quality of the meat) and that the liquid temperature does not affect the performance of the refrigerator itself (too high a temperature will affect the performance of the refrigerator). Therefore, to ensure the quality of the meat's thawing effect and not affect the performance of the refrigerator, it is necessary to control the thawing process by detecting the liquid temperature and liquid resistance of the water (because the temperature of the meat itself is difficult to detect).

[0089] In one embodiment of the present application, if the internal environment information includes liquid temperature and liquid resistance, the refrigerator further comprises: a temperature sensor disposed in the thawing box, for detecting the liquid temperature of the liquid environment in which the items to be thawed are currently located in the thawing box; a resistance sensor disposed in the thawing box, for detecting the liquid resistance of the liquid environment in which the items to be thawed are currently located in the thawing box;

[0090] Accordingly, when the controller adjusts the power-on voltage of the two electrode plates according to the internal environmental information of the thawing box to adjust the thawing power, it is configured to: adjust the power-on voltage of the two electrode plates to the target voltage corresponding to the current liquid resistance, and thaw the items to be thawed by the thawing power corresponding to the target voltage; in the process of thawing the items to be thawed by the thawing power corresponding to the target voltage, if it is detected that the liquid temperature does not fall within the ideal temperature range, the power-on voltage is adjusted to zero, and after it is detected that the liquid temperature falls within the ideal temperature range, the power-on voltage is adjusted to the target voltage corresponding to the current liquid resistance.

[0091] In another embodiment of the present application, if the internal environment information includes liquid temperature and liquid resistance; the refrigerator further comprises: a temperature sensor, disposed in the thawing box, for detecting the liquid temperature of the liquid environment in which the items to be thawed are currently located in the thawing box; a resistance sensor, disposed in the thawing box, for detecting the liquid resistance of the liquid environment in which the items to be thawed are currently located in the thawing box;

[0092] Accordingly, when the controller adjusts the distance between the two electrode plates according to the internal environmental information of the thawing box to adjust the thawing power, it can also be configured to: adjust the distance between the two electrode plates to the target distance corresponding to the current liquid resistance, and thaw the items to be thawed using the thawing power corresponding to the target distance; in the process of thawing the items to be thawed using the thawing power corresponding to the target distance, if it is detected that the liquid temperature does not fall within the ideal temperature range, the thawing power is adjusted to zero, and after it is detected that the liquid temperature falls within the ideal temperature range, the thawing power is adjusted to the thawing power corresponding to the target distance corresponding to the current liquid resistance.

[0093] It is further explained that when it is necessary to obtain the liquid resistance of the liquid environment in which the items to be thawed are located, other methods may also be included, such as the electrode contact method, the non-contact electromagnetic induction method and the standardized instrument measurement method. In summary, there are many methods for obtaining the liquid resistance of the liquid environment in which the items to be thawed are located, and they will not be described one by one here. The following will explain the above three methods for measuring liquid resistance: (1) When the electrode contact method is used to obtain the liquid resistance, a variable resistor can be used in series with the liquid resistor, and the resistance value is calculated by measuring the voltage across the liquid and the loop current; (2) When the non-contact electromagnetic induction method is used to obtain the liquid resistance, an alternating magnetic field is emitted by a double magnetic coil probe, and the eddy current induced in the liquid forms a secondary magnetic field. The receiving coil detects the strength of the secondary magnetic field and compares it with the emitted magnetic field to indirectly calculate the liquid resistance of the liquid; (3) When the standardized instrument is used for measurement, the liquid can be injected into the resistance pool of the standardized instrument and the bubbles are discharged. After inserting the temperature sensor and the electrode, the liquid resistance fed back by the standardized instrument can be directly read.

[0094] It is further explained that when it is necessary to obtain the liquid temperature of the liquid environment in which the items to be thawed are located, other methods can also be used, such as measurement through a thermistor; when measuring through a thermistor, the temperature-resistance correspondence table provided by the manufacturer can be obtained in advance, and then, after immersing the thermistor in the liquid environment, the resistance value of the thermistor is read, and the liquid temperature can be determined according to the correspondence table.

[0095] It should be noted that in the process of adjusting the power-on voltage of the two electrode plates to the target voltage corresponding to the current liquid resistance, and adjusting the distance between the two electrode plates to the target distance corresponding to the current liquid resistance, the target point is to adjust the thawing power from the first thawing power to the second thawing power.

[0096] In one embodiment of the present application, during the process of thawing the items to be thawed, it can be determined whether the liquid resistance at the current moment corresponds to the target distance or target voltage at the current moment. If it corresponds, the thawing power is adjusted according to the relationship between the liquid temperature and the ideal temperature range; if it does not correspond, the target distance or target voltage is adjusted to ensure that, during the process of thawing the items to be thawed, the liquid resistance and the target distance or target voltage remain corresponding at all times.

[0097] Among them, the correspondence between the liquid resistance and the target distance or target voltage may include a first correspondence between the liquid resistance and the target distance, and a second mapping relationship between the liquid resistance and the target voltage; wherein the first correspondence records different target distances corresponding to different liquid resistances; and the second correspondence records different target voltages corresponding to different liquid resistances.

[0098] In one embodiment of the present application, the maximum number of thawing power adjustments can be pre-specified. Then, after the starting thawing power is selected, the items to be thawed are thawed according to the above content. If the number of adjustments to the thawing power reaches the maximum number of thawing power adjustments, it is determined that the thawing of the items to be thawed is completed.

[0099] As an example, if the maximum thawing power adjustment times are predetermined to be four times, the thawing voltage can be pre-set to four gears, namely U1, U2, U3, and U4 (U1>U2>U3>U4); specifically, when the thawing voltage is U1 (the thawing power corresponding to U1 is taken as the first thawing power); if at this time the liquid resistance R is greater than the preset first resistance threshold R1 (at this time the liquid resistance R corresponds to the thawing voltage U1, then the thawing voltage U1 is the target voltage), the thawing process is performed on the to-be-thawed items by the current thawing voltage U1, and after running for a period of time t1 under the condition that the liquid temperature T does not exceed the first temperature threshold T1 (the liquid temperature is within the ideal temperature range), if it is detected that the first resistance threshold R1>liquid resistance R>first resistance threshold R2 (At this time, the liquid resistance R corresponds to the thawing voltage U2, and the thawing voltage U2 is the target voltage) the thawing voltage is adjusted from U1 to U2 to adjust the first thawing power and obtain the second thawing power; when the liquid temperature T does not exceed the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed at the current thawing voltage U2; if the liquid temperature T exceeds the second temperature threshold T2 (the liquid temperature is not within the ideal temperature range), the thawing operation of the thawing device is stopped, so that the second thawing power is set to zero, and when the liquid temperature T drops below the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed again by the thawing voltage U2 (this stage takes time t2). If it is detected that the second resistance threshold R2>liquid resistance R>third resistance threshold R3 (at this time the liquid resistance R corresponds to the thawing voltage U3, and the thawing voltage U3 is the target voltage), the thawing voltage is adjusted from U2 to U3 to adjust the second thawing power to obtain the third thawing power; when the liquid temperature T does not exceed the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed at the current thawing voltage U3; if the liquid temperature T exceeds the second temperature threshold T2 (the liquid temperature is not within the ideal temperature range), the thawing operation of the thawing device is stopped, and the third thawing power is set to zero. When the liquid temperature T drops below the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed again by the thawing voltage U3 (this stage takes time t3).If it is detected that the third resistance threshold R3 is greater than the liquid resistance R (at this time the liquid resistance R corresponds to the thawing voltage U4, and the thawing voltage U4 is the target voltage), the thawing voltage is adjusted from U3 to U4 to adjust the third thawing power and obtain the fourth thawing power; when the liquid temperature T does not exceed the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the thawing item to be thawed is continuously thawed for t4 time to complete the thawing operation; if the liquid temperature T exceeds the second temperature threshold T2 (the liquid temperature is not within the ideal temperature range), the thawing equipment is stopped for a period of time t5. When the liquid temperature T drops below the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the thawing item to be thawed is thawed by the thawing voltage U4 for a period of time t6. This process is repeated for a maximum of two cycles, that is, 2(t5+t6), and then the thawing program is ended.

[0100] In the current state, the longest time for thawing is: t1+t2+t3+t4 or t1+t2+t3+2(t5+t6).

[0101] As another example, if the maximum thawing power adjustment times are predetermined to be four times, the interval distance between the two electrode plates can be preset to four gears, namely D1, D2, D3, and D4 (D1>D2>D3>D4); specifically, when the interval distance is D1 (the thawing power corresponding to D1 is taken as the first thawing power); if at this time the liquid resistance R is greater than the preset first resistance threshold R1 (at this time the liquid resistance R corresponds to the interval distance D1, then the interval distance D1 is the target distance), the thawing process is performed on the thawing items through the current interval distance D1, and after running for a period of time t1 under the condition that the liquid temperature T does not exceed the first temperature threshold T1 (the liquid temperature is within the ideal temperature range), if it is detected that the first resistance threshold R1>liquid resistance R>first resistance threshold R 2 (at this time, the liquid resistance R corresponds to the interval distance D2, and the interval distance D2 is the target distance), the interval distance is adjusted from D1 to the interval distance D2, so as to adjust the first thawing power and obtain the second thawing power; when the liquid temperature T does not exceed the second temperature threshold value T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed at the current interval distance D2; if the liquid temperature T exceeds the second temperature threshold value T2 (the liquid temperature is not within the ideal temperature range), the thawing operation of the thawing device is stopped, so that the second thawing power is set to zero, and when the liquid temperature T drops below the second temperature threshold value T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed again through the interval distance D2 (this stage takes time t2). If it is detected that the second resistance threshold R2>liquid resistance R>third resistance threshold R3 (at this time the liquid resistance R corresponds to the interval distance D3, and the interval distance D3 is the target distance), the interval distance is adjusted from D2 to the interval distance U3 to adjust the second thawing power and obtain the third thawing power; when the liquid temperature T does not exceed the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed at the current interval distance U3; if the liquid temperature T exceeds the second temperature threshold T2 (the liquid temperature is not within the ideal temperature range), the thawing operation of the thawing device is stopped, and the third thawing power is set to zero. When the liquid temperature T drops below the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the items to be thawed are thawed again through the interval distance U3 (this stage takes time t3).If it is detected that the third resistance threshold R3>liquid resistance R (at this time the liquid resistance R corresponds to the interval distance D4, and the interval distance D4 is the target distance), the interval distance is adjusted from D3 to the interval distance D4 to adjust the third thawing power and obtain the fourth thawing power; when the liquid temperature T does not exceed the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the thawing items to be thawed are continuously thawed for t4 time to complete the thawing operation; if the liquid temperature T exceeds the second temperature threshold T2 (the liquid temperature is not within the ideal temperature range), the thawing equipment is stopped for a period of time t5. When the liquid temperature T drops below the second temperature threshold T2 (the liquid temperature is within the ideal temperature range), the thawing items to be thawed are thawed through the interval distance D4 for a period of time t6. This process is repeated for a maximum of two cycles, that is, 2(t5+t6) before the thawing program is ended.

[0102] In the current state, the longest time for thawing is: t1+t2+t3+t4 or t1+t2+t3+2(t5+t6).

[0103] In summary, the items to be thawed are thawed by the target voltage or target distance corresponding to the liquid resistance; it is realized that whether the current liquid environment is suitable for thawing the items to be thawed is judged according to different liquid temperatures, thereby ensuring uniform thawing inside and outside of the items to be thawed, and achieving the maximum improvement of thawing efficiency while preventing waste of thawing energy.

[0104] In some embodiments, in order to ensure the safety of electricity use of the thawing box, a safety protection mechanism can be set up to achieve power-off protection for the thawing box and the refrigerator under special circumstances; specifically, when the thawing box is placed in the target position inside the refrigerator box, the powered female head of the thawing box is in contact and connected with the powered male head of the refrigerator box; the controller is also configured to, after detecting an opening event of the target door corresponding to the thawing box in the refrigerator box, cut off the power to the relay corresponding to the thawing box; when the thawing box is not in the target position, the powered female head of the thawing box is disconnected from the powered male head of the refrigerator box.

[0105] Among them, the target door refers to the refrigerator door corresponding to the area where the thawing box is located.

[0106] As an example, when the thawing box is placed in the target position inside the refrigerator box, if the target door of the refrigerator box is opened, it means that the user may take the items to be thawed inside the thawing box. In order to ensure that the user does not face the risk of electric shock when taking the items to be thawed, after the door opening event of the target door corresponding to the thawing box in the refrigerator box is detected, the power to the relay corresponding to the thawing box is cut off to ensure that the power to the thawing box is cut off after the target door is opened.

[0107] As another example, when the thawing box is placed in the target position inside the refrigerator box, if the thawing box is removed from the target position, the energized female connector of the thawing box and the energized male connector of the refrigerator box will be disconnected, thereby ensuring that after the thawing box is removed from the target position of the refrigerator box, the power to the relay corresponding to the thawing box is cut off to prevent the user from being electrocuted. Figure 18 As shown, the power supply female connector of the thawing box is as follows Figure 19 shown.

[0108] The power frequency of the refrigerator's external power supply may be 50 Hz or other frequencies, and the power frequency is not limited here.

[0109] To sum up, this application realizes power-off protection for the thawing box and refrigerator under special circumstances by setting up a safety protection mechanism, ensuring that there is no risk of electric shock when the user operates the refrigerator, and ensuring the safety of user operation.

[0110] In some embodiments, the present application provides a refrigerator thawing method, which is applied to a controller in the refrigerator.

[0111] like Figure 20 As shown, the method includes:

[0112] S2001 , in response to a thawing instruction, energizing the two electrode plates to perform ohmic heating on the object to be thawed located between the two electrode plates, so as to thaw the object to be thawed.

[0113] It should be noted that one or both of the two electrode plates are detachable electrode plates, and a plurality of grooves are provided in the thawing box, which are at least used to place the detachable electrode plates so as to adjust the thawing power by changing the distance between the two electrode plates.

[0114] S2002: During the thawing process of the items to be thawed, the voltage and / or distance between the two electrode plates are adjusted according to the internal environment information of the thawing box to adjust the thawing power.

[0115] It should be noted that the internal environmental information includes liquid temperature and liquid resistance. Therefore, when adjusting the distance between the two electrode plates to adjust the thawing power according to the internal environmental information of the thawing box, it may include the following: adjusting the distance between the two electrode plates to the target distance corresponding to the current liquid resistance, and thawing the items to be thawed with the thawing power corresponding to the target distance; in the process of thawing the items to be thawed with the thawing power corresponding to the target distance, if it is detected that the liquid temperature is not within the ideal temperature range, the thawing power is adjusted to zero, and after detecting that the liquid temperature is within the ideal temperature range, the thawing power is adjusted to the thawing power corresponding to the target distance corresponding to the current liquid resistance.

[0116] Further, when adjusting the distance between the two electrode plates to adjust the thawing power according to the internal environment information of the thawing box, the following steps may also be included: adjusting the voltage across the two electrode plates to a target voltage corresponding to the current liquid resistance, and thawing the to-be-thawed items using the thawing power corresponding to the target voltage;

[0117] During the process of thawing the items to be thawed using the thawing power corresponding to the target voltage, if it is detected that the liquid temperature is not within the ideal temperature range, the power-on voltage is adjusted to zero, and after it is detected that the liquid temperature is within the ideal temperature range, the power-on voltage is adjusted to the target voltage corresponding to the current liquid resistance.

[0118] In summary, by placing the thawing box inside the refrigerator box, it is convenient to directly thaw the items to be thawed inside the refrigerator, thereby achieving seamless compatibility between the thawing box and the refrigerator box; and, by energizing the two electrode plates, the items to be thawed located between the two electrode plates are ohmically heated, thereby ensuring that the items to be thawed can be ohmically thawed, thereby achieving rapid thawing of the items to be thawed, improving the thawing efficiency of the items to be thawed, and during the thawing process, the power-on voltage and / or distance of the two electrode plates are adjusted according to the internal environmental information of the thawing box, so that the items to be thawed can be in the optimal thawing state, thereby maximizing the guarantee that the quality of the items to be thawed will not be affected by the thawing operation, thereby achieving the guarantee of the quality of the items to be thawed while ensuring that the thawing efficiency of the items to be thawed is not affected.
