Description

Technical Field

[0001] This invention relates to the technical field of thawing, and particularly to a thawing control method, system, thawing device, refrigerator, and storage medium. Background Technology

[0002] Frozen foods must be thawed before processing or consumption, and thawing is one of the important factors affecting the final quality of frozen meat products. Improper thawing methods can cause excessive degradation of the physical, chemical, and sensory qualities of meat products, such as juice loss, protein denaturation, fat oxidation, and odor deterioration.

[0003] There are various forms of thawing technology, such as water thawing, air thawing, and microwave thawing. However, existing thawing technologies suffer from problems such as slow thawing speed, poor thawing quality, and uncontrollable thawing endpoint. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of slow thawing speed in the prior art, and to provide a thawing control method, system, thawing device, refrigerator and storage medium.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A thawing control method for thawing an object, the thawing control method comprising the following steps:

[0007] Identify the placement location of the item to be thawed;

[0008] Adjust the output direction of the defrosting power source according to the placement location so that the output energy is directed toward the placement location;

[0009] Start the defrosting power source.

[0010] In this scheme, the thawing control method adjusts the output direction of the thawing power source according to the placement position of the object to be thawed, thereby achieving directional energy output, concentrating the energy on the object to be thawed, and improving the thawing speed.

[0011] Preferably, the method for the step of "identifying the location of the object to be thawed" specifically includes:

[0012] The temperature of the placement platform on which the object to be thawed is placed is detected at different locations;

[0013] The placement of the item to be thawed is determined based on the temperature at different locations.

[0014] or,

[0015] The pressure at different locations on the placement platform where the object to be thawed is placed is measured;

[0016] The placement position of the object to be thawed is determined based on the pressure difference at different locations.

[0017] In this solution, the placement of the object to be thawed is accurately determined by the temperature difference or the pressure difference at different locations, thus avoiding the impact of inaccurate location determination on the effectiveness and efficiency of directional thawing.

[0018] Preferably, the step of "determining the placement position of the object to be thawed based on the pressure difference at different locations" specifically includes:

[0019] The placement position of the object to be thawed is determined based on the pressure difference between different locations before and after placement.

[0020] In this solution, by using the pressure difference between the object to be thawed and the object before and after placement, the placement position of the object to be thawed can be determined more accurately.

[0021] Preferably, the thawing control method further includes:

[0022] The weight of the object to be thawed is obtained, and the output power of the thawing power source is adjusted according to the weight of the object to be thawed.

[0023] And / or,

[0024] The temperature of the object to be thawed is detected, and the output power of the thawing power source is adjusted based on the difference between the detected temperature and the target temperature, as well as the target thawing time.

[0025] In this solution, the above method can be used to adjust the output power of the defrosting power source according to the different weights of the items to be defrosted, and / or adjust the output power of the defrosting power source according to the different initial temperature states of the items to be defrosted, so that the defrosting output power matches the weight and initial temperature, and realizes adaptive adjustment of the output level, which is beneficial to improving defrosting efficiency.

[0026] Preferably, the thawing control method further includes:

[0027] Obtain the weight of the object to be thawed;

[0028] Obtain the initial temperature of the object to be thawed;

[0029] The thawing time for the thawing power source to operate continuously is calculated based on the weight of the object to be thawed, the initial temperature, the target temperature, and the operating power of the thawing power source.

[0030] In this solution, the above method allows users to predict the defrosting time, enabling intelligent timing and automatic stopping when the time is up, reminding users that the defrosting process is complete and improving the user experience.

[0031] Preferably, the step of "obtaining the initial temperature of the object to be thawed" specifically includes:

[0032] The temperature of the platform on which the object to be thawed is placed is detected at different locations, and the lowest detection temperature is calculated based on the detected temperatures at different locations. The lowest detection temperature is then set as the initial temperature.

[0033] In this solution, the initial temperature setting is more accurate through the above method, thereby improving the accuracy of the thawing time and avoiding affecting the thawing quality.

[0034] Preferably, the thawing control method further includes:

[0035] During the thawing process, the temperature of the platform on which the object to be thawed is placed is monitored in real time at different locations, and the lowest detection temperature is calculated based on the monitored temperatures at different locations.

[0036] The thawing time is adjusted based on the weight of the object to be thawed, the minimum detection temperature, the target temperature, and the operating power of the thawing power source.

[0037] In this solution, the above method allows for real-time adjustment of the thawing time based on the thawing speed at different locations of the object to be thawed. This prevents some locations from thawing slowly and remaining at a low temperature, yet being treated as having a higher temperature like other locations, resulting in insufficient thawing time for the object to be thawed completely. This improves the thawing quality.

[0038] Preferably, the method for the step of "obtaining the weight of the object to be thawed" specifically includes:

[0039] The pressure of the placement platform on which the object to be thawed is placed is detected at different positions before and after placement, and the pressure difference at each position before and after placement is calculated.

[0040] The weight of the object to be thawed is calculated based on the pressure difference at each location; wherein, the formula for calculating the weight of the object to be thawed is: weight of the object to be thawed = sum of the pressure differences at each location / gravitational acceleration.

[0041] In this solution, the sum of the pressure differences at each position on the placement platform before and after placement, as described above, reflects the cumulative weight at each position. Compared to methods that detect weight at a single or partial position or calculate weight without considering pressure differences, this method improves the accuracy of weight calculation. This helps to accurately control the thawing time and avoids deviations in the calculated thawing time due to inaccurate weight, which in turn affects the thawing quality.

[0042] Preferably, the defrosting power source includes a fan, and the step of "adjusting the output direction of the defrosting power source according to the placement position" specifically means: adjusting the output airflow direction of the fan according to the placement position.

[0043] In this solution, the above method is used to adjust the output airflow of the fan to achieve directional airflow, thereby improving the effectiveness and efficiency of defrosting.

[0044] Preferably, the defrosting power source includes a first heating element, and the step of "adjusting the output direction of the defrosting power source according to the placement position" specifically means: adjusting the output direction of the first heating element according to the placement position.

[0045] In this solution, directional heating is achieved by adjusting the output direction of the first heating element through the above method, thereby improving the effectiveness and efficiency of defrosting.

[0046] Preferably, the defrosting power source further includes a second heating element, and the defrosting control method further includes:

[0047] The weight of the object to be thawed is detected, and it is determined whether the weight of the object to be thawed is greater than the set standard weight. If so, the second heating element is activated to heat the object.

[0048] And / or,

[0049] The initial temperature of the object to be thawed is detected, and it is determined whether the initial temperature is lower than the set starting heating temperature. If so, the second heating element is activated to heat the object.

[0050] In this solution, by determining whether the weight of the object to be thawed is greater than the set standard weight, and / or by determining whether the initial temperature is less than the set starting heating temperature, it is possible to control whether it is necessary to activate a second heating element for heating under directional air blowing, thereby improving thawing efficiency.

[0051] Preferably, the defrosting power source further includes a third heating element, and the defrosting control method further includes:

[0052] Detect the temperature value of the compartment where the object to be thawed is placed;

[0053] Determine whether the cabin temperature is lower than the set first limit temperature value; if so, activate the third heating element to heat the cabin.

[0054] And / or,

[0055] Determine whether the temperature of the chamber is greater than the set second limit temperature value. If so, stop the heating operation of the third heating element.

[0056] In this solution, the third heating element is activated using the method described above to prevent the chamber temperature from becoming too low (below the set first limit temperature value) and affecting other surrounding equipment. This ensures the chamber maintains a normal, relatively constant temperature environment, preventing slow thawing or lowering the temperature of the surrounding area due to excessively low temperatures, which could damage the items being thawed. Simultaneously, the third heating element provides additional heating to accelerate the thawing process. When the chamber temperature is determined to be high (above the set second limit temperature value), the third heating element is deactivated, saving energy and preventing excessively rapid thawing that could affect quality.

[0057] Preferably, the thawing control method further includes:

[0058] Different target temperatures are set according to the type of the item to be thawed.

[0059] In this solution, the above method allows users to select their preferred thawed firmness based on the different types of items to be thawed, thereby setting the corresponding target temperature. This provides greater flexibility and facilitates control over the thawing endpoint as needed, improving thawing quality.

[0060] A defrosting control system is provided for implementing the defrosting control method described above. The defrosting control system includes:

[0061] A first detection module is used to identify the placement position of the object to be thawed.

[0062] A first control module is configured to adjust the output direction of the defrosting power source according to the placement position, so that the output energy is directed toward the placement position.

[0063] The second control module is used to start the defrosting power source.

[0064] In this scheme, the thawing control system enables the above-mentioned thawing control method to achieve directional energy output, so that the energy is more concentrated on the object to be thawed, thereby improving the thawing speed.

[0065] A thawing device is provided, wherein the thawing device uses the thawing control method described above to thaw an object to be thawed. The thawing device includes a thawing control system, a thawing power source, and a housing as described above. The object to be thawed and the thawing power source are both placed inside the housing. The thawing power source is used to generate energy and act on the object to be thawed to raise the temperature of the object to be thawed to a set target temperature.

[0066] In this solution, the defrosting device, which includes the aforementioned defrosting control system, achieves directional energy output, allowing energy to be applied more concentratedly to the object to be defrosted, thereby increasing the defrosting speed.

[0067] A refrigerator comprising the defrosting device as described above.

[0068] In this solution, the refrigerator achieves directional energy output through the aforementioned defrosting device, allowing energy to be applied more concentratedly to the items to be defrosted, thereby increasing the defrosting speed.

[0069] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the unfreezing control method described above.

[0070] In this scheme, the computer-readable storage medium stores the program for the defrosting control method.

[0071] The positive and progressive effects of this invention are as follows: by adjusting the output direction of the defrosting power source according to the placement position of the object to be defrosted, the defrosting control method, system, defrosting device, refrigerator and storage medium achieve directional energy output, and the energy acts more concentratedly on the object to be defrosted, thereby improving the defrosting speed.

[0091] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0092] Example 1

[0093] This embodiment provides a thawing control method for thawing an object (e.g., frozen fish). When applying this thawing control method, the object to be thawed is placed in a thawing device 1, such as... Figure 3 As shown, the defrosting device 1 includes a defrosting power source 3, a housing 2, and other components. The defrosting power source 3 specifically includes a fan 4 and a heating element 5. The object to be defrosted 12 is placed on a placement platform 6, which is a defrosting plate. Four pressure sensors 9 are attached to the lower surface of the defrosting plate, distributed in the four corners. Several temperature sensors 8 are also attached to the lower surface of the defrosting plate, distributed in different positions to ensure that no matter where the object to be defrosted 12 is, some temperature sensors 8 are located closest to the object to be defrosted 12. The surface of the defrosting plate is covered with heat-insulating material to isolate the defrosting plate from the bottom wall of the housing 2.

[0094] The heating element 5 is specifically a heating plate. A heat-conducting block 13 is sandwiched between the fan 4 and the heating plate. The heating element 5 is in close contact with the plane of the heat-conducting block 13. The fin surface of the heat-conducting block 13 is in close contact with the air inlet surface of the fan 4. The air outlet surface of the fan 4 faces downward. The three are connected to the top of the housing 2. The fan cover 11 with several air guides 10 is also fixed to the top of the housing 2 and covers the fan 4. The air guides 10 and the fan cover 11 are rotatably connected. The drive mechanism of the air guides 10 (not shown in the figure) can drive the air guides 10 to rotate.

[0095] The object to be thawed 12, fan 4, and heating element 5 are all placed inside the box 2. Fan 4 blows heat from heating element 5 to form hot air. The hot air is directionally guided by air guide 10 and blown to the surface of object to be thawed 12 to raise the temperature of object to be thawed 12 to the target temperature and complete the thawing.

[0096] like Figure 1 As shown, the thawing control method includes the following steps:

[0097] S1. Identify the location of the item to be thawed;

[0098] S2. Adjust the output direction of the defrosting power source according to the placement location so that the output energy is directed towards the placement location;

[0099] S3. Activate the defrosting power source.

[0100] This thawing control method achieves directional energy output by adjusting the output direction of the thawing power source according to the placement position of the object to be thawed. This allows the energy to be applied more concentratedly to the object, thereby increasing the thawing speed.

[0101] There can be various forms of defrosting power source. In this embodiment, the defrosting power source includes a fan and a heating element. In step S3, the fan can be started or the heating element can be started as needed. Alternatively, one or both of the two power sources can be selected at different stages to carry out the defrosting work.

[0102] Specifically, the method for step S1, "identifying the location of the object to be thawed," includes:

[0103] S11. Detect the temperature at different locations on the platform where the items to be thawed are placed;

[0104] S12. Determine the placement of the item to be thawed based on the temperature at different locations;

[0105] In other embodiments, the placement position of the object to be thawed can also be determined based on pressure. In this case, the method for step S1, "identifying the position of the object to be thawed," can also include the following steps:

[0106] S13. Detect the pressure at different locations on the placement platform where the items to be thawed are placed;

[0107] S14. Determine the placement of the item to be thawed based on the pressure difference at different locations.

[0108] This thawing control method accurately determines the placement of the object to be thawed by measuring the temperature or pressure difference at different locations, thus avoiding inaccurate location determination that could affect the effectiveness and efficiency of directional thawing.

[0109] Specifically, step S14, "determining the placement position of the object to be thawed based on the pressure difference at different locations," includes:

[0110] S141. Determine the placement position of the item to be thawed based on the pressure difference between the pre-placement and post-placement locations.

[0111] By using the above method, the pressure difference between the object to be thawed before and after placement can be used to more accurately determine the placement position of the object to be thawed.

[0112] The thawing control method also includes:

[0113] S41. Obtain the weight of the item to be thawed, and adjust the output power of the thawing power source according to the weight of the item to be thawed;

[0114] In other embodiments, the output power of the defrosting power source can be adjusted according to the detected temperature, and step S41 can also be changed to:

[0115] S42. Detect the temperature of the object to be thawed, and adjust the output power of the thawing power source according to the difference between the detected temperature and the target temperature, as well as the target thawing time.

[0116] In other embodiments, steps S41 and S42 described above can also be used simultaneously to adjust the output power of the defrosting power source.

[0117] The above method allows for adjusting the output power of the defrosting power source based on the weight of the food to be defrosted, and / or based on the initial temperature of the food, ensuring that the defrosting output power matches the weight and initial temperature. This adaptive adjustment of the output level improves defrosting efficiency. In this embodiment, this level adjustment is reflected in matching different fan speeds (e.g., adjusting the duty cycle of the fan motor via PWM; the greater the weight of the food, the higher the duty cycle, the higher the fan speed, and the faster the defrosting) and / or different heating power levels based on different weights.

[0118] The thawing control method also includes:

[0119] S5. Obtain the weight of the item to be thawed;

[0120] S6. Obtain the initial temperature of the object to be thawed;

[0121] S7. Calculate the thawing time for the thawing power source to work continuously, based on the weight of the object to be thawed, the initial temperature, the target temperature, and the working power of the thawing power source.

[0122] Using the above methods, users can predict the defrosting time, achieve intelligent timing, and automatically stop when the time is up, reminding them that the defrosting process is complete, thus improving the user experience.

[0123] Specifically, step S6, "obtaining the initial temperature of the object to be thawed," includes:

[0124] S61. Detect the temperature of the placement platform on which the object to be thawed is placed at different locations, and calculate the minimum detection temperature based on the detection temperature at different locations, and set the minimum detection temperature as the initial temperature.

[0125] By using the above method, the initial temperature setting is more accurate, thereby improving the accuracy of the thawing time and avoiding affecting the thawing quality.

[0126] The thawing control method also includes:

[0127] S8. During the thawing process, the temperature of the platform where the items to be thawed are placed is monitored in real time at different locations, and the lowest detection temperature is calculated based on the monitored temperatures at different locations.

[0128] S9. Adjust the thawing time according to the weight of the object to be thawed, the minimum detection temperature, the target temperature, and the working power of the thawing power source.

[0129] By using the above method, the thawing time can be adjusted in real time according to the thawing speed of different parts of the object to be thawed. This avoids situations where some parts thaw slowly and are still at a low temperature, but are treated as having a higher temperature like other parts, resulting in insufficient thawing time for the object to be thawed completely. This helps to improve the thawing quality.

[0130] Specifically, the method for "obtaining the weight of the object to be thawed" in steps S41 and S5 includes:

[0131] S410. Detect the pressure of the placement platform for the object to be thawed at different positions before and after placement, and calculate the pressure difference at each position before and after placement.

[0132] S420. Calculate the weight of the object to be thawed based on the pressure difference at each location; the formula for calculating the weight of the object to be thawed is: weight of the object to be thawed = sum of pressure differences at each location / gravitational acceleration.

[0133] Using the above method, the sum of the pressure differences at each position on the placement platform before and after placement reflects the cumulative weight at each position. Compared with methods that detect weight at a single or partial position or calculate weight without pressure difference, this method improves the accuracy of weight calculation. This helps to accurately control the thawing time and avoids deviations in the calculated thawing time due to inaccurate weight, which in turn affects the thawing quality.

[0134] In this embodiment, the defrosting power source includes a fan, and the above step S2 "adjust the output direction of the defrosting power source according to the placement position" specifically means: adjusting the output airflow direction of the fan according to the placement position.

[0135] By adjusting the fan's output direction using the above method, directional airflow is achieved, thereby improving the effectiveness and efficiency of defrosting.

[0136] In this embodiment, the defrosting power source also includes a heating element. In this embodiment, the heating element is the first heating element. Therefore, the above step S2 "adjust the output direction of the defrosting power source according to the placement position" can also be: adjust the output direction of the first heating element according to the placement position.

[0137] By adjusting the output direction of the first heating element using the above method, directional heating is achieved, thereby improving the effectiveness and efficiency of defrosting.

[0138] In other embodiments, there may be multiple heating elements, or different heating structures. Therefore, one or more of them can be selected as needed to adjust the output power and output direction.

[0139] When applying this defrosting control method, depending on the weight of the object to be defrosted, if the weight is small, only the fan needs to be activated for defrosting. However, if there are many objects to be defrosted and the weight is large, the heating element can also be activated simultaneously for defrosting. In this case, the defrosting control method also includes:

[0140] S100: Detect the weight of the object to be thawed, determine whether the weight is greater than the set standard weight, and if so, start the heating element to heat.

[0141] In this embodiment, the heating element in step S10 is the first heating element. However, as mentioned above, the defrosting power source may include multiple heating elements, which are used for heating at different stages and locations. In other embodiments, when the defrosting power source includes a second heating element, step S10 can be changed to activating the second heating element for heating.

[0142] In other embodiments, the second heating element can be activated based on the initial temperature. The specific steps are as follows:

[0143] S101. Detect the initial temperature of the object to be thawed, determine whether the initial temperature is lower than the set starting heating temperature, and if so, start the second heating element to heat.

[0144] By determining whether the weight of the object to be thawed is greater than the set standard weight, and / or by determining whether the initial temperature is less than the set starting heating temperature, it is possible to control whether it is necessary to activate a second heating element for heating under directional air blowing, thereby improving thawing efficiency.

[0145] In this embodiment, the thawing control method further includes:

[0146] S102. Detect the temperature value of the compartment where the items to be thawed are placed;

[0147] S103. Determine whether the cabin temperature is less than the set first limit temperature value. If so, start the first heating element to heat the cabin.

[0148] In this step S103, the first limit temperature value can be a lower temperature that does not affect the operation of other equipment in the refrigerator, or it can be a critical temperature that requires heating in addition to fan defrosting. If the compartment temperature is higher than the first limit temperature value, then only fan defrosting is needed. However, if it is lower than the first limit temperature value, it means that the compartment temperature is too low and not within the normal defrosting range. More heat is needed to quickly raise the temperature of the compartment, so additional heating is required to restore the compartment temperature to the normal range.

[0149] In this embodiment, the thawing control method further includes:

[0150] S104. Determine whether the cabin temperature is greater than the set second limit temperature. If so, stop the heating operation of the first heating element.

[0151] In this step S104, the second limit temperature value is the temperature value at which heating restores the cabin temperature to the normal temperature range. Once the normal temperature is restored, there is no need to continue heating.

[0152] As described above, the defrosting power source may include multiple heating elements. In other embodiments, when the defrosting power source includes a third heating element, the "first heating element" that performs the heating operation in steps S103 and S104 can be replaced by the "third heating element" or other heating components.

[0153] The above method activates the heating element to prevent the chamber temperature from becoming too low (below the set first limit temperature value), which could affect other surrounding equipment. This ensures the chamber maintains a normal, relatively constant temperature environment, preventing slow thawing or lowering the temperature of the surrounding area due to excessively low temperatures, thus avoiding damage to the items being thawed. The heating element also provides an additional thawing method, accelerating the thawing process. When the chamber temperature is determined to be high (above the set second limit temperature value), the heating element's operation is stopped, saving energy and preventing excessively rapid thawing that could affect quality.

[0154] The thawing control method also includes:

[0155] S15. Set different target temperatures according to the type of the item to be thawed.

[0156] The above method allows users to select their preferred thaw firmness based on the different types of items to be thawed, thereby setting the corresponding target temperature. This provides greater flexibility and allows for better control of the thawing endpoint, improving thawing quality.

[0157] Example 2

[0158] This embodiment provides a thawing control system for implementing the thawing control method as described in Embodiment 1.

[0159] like Figure 2 As shown, the defrosting control system includes:

[0160] The first detection module 100 is used to identify the placement position of the object to be thawed;

[0161] The first control module 200 is used to adjust the output direction of the defrosting power source according to the placement position, so that the output energy is directed towards the placement position.

[0162] The second control module 300 is used to start the defrosting power source.

[0163] The above-mentioned thawing control method achieves directional energy output through the thawing control system, which concentrates energy on the object to be thawed and improves the thawing speed.

[0164] Example 3

[0165] like Figure 3 As shown, a thawing device 1 is disclosed. This thawing device 1 uses the thawing control method as described in Example 1 to thaw an object 12 (e.g., frozen fish). The thawing device 1 includes a thawing control system as described in Example 2, a thawing power source 3, and a housing 2, among other components. The thawing power source 3 specifically includes a fan 4 and a heating element 5. The object 12 to be thawed is placed on a placement platform 6, which is specifically a thawing plate. Four pressure sensors 9 are attached to the lower surface of the thawing plate, distributed at the four corners. Several temperature sensors 8 are also attached to the lower surface of the thawing plate, distributed in different positions to ensure that, regardless of the position of the object 12, some temperature sensors 8 are located closest to the object 12. The surface of the thawing plate is covered with heat-insulating material to isolate the thawing plate from the bottom wall of the housing 2.

[0166] The heating element 5 is specifically a heating plate. A heat-conducting block 13 is sandwiched between the fan 4 and the heating plate. The heating element 5 is in close contact with the plane of the heat-conducting block 13. The fin surface of the heat-conducting block 13 is in close contact with the air inlet surface of the fan 4. The air outlet surface of the fan 4 faces downward. The three are connected to the top of the housing 2. The fan cover 11 with several air guides 10 is also fixed to the top of the housing 2 and covers the fan 4. The air guides 10 and the fan cover 11 are rotatably connected. The drive mechanism of the air guides 10 (not shown in the figure) can drive the air guides 10 to rotate.

[0167] The object to be thawed 12, fan 4, and heating element 5 are all placed inside the box 2. Fan 4 blows heat from heating element 5 to form hot air. The hot air is directionally guided by air guide 10 and blown to the surface of object to be thawed 12 to raise the temperature of object to be thawed 12 to the target temperature and complete the thawing.

[0168] The thawing device 1 achieves directional airflow through the aforementioned thawing control system, thereby directing energy output in a more focused manner and concentrating the energy on the object to be thawed, thus increasing the thawing speed.

[0169] Example 4

[0170] This embodiment provides a refrigerator that includes a defrosting device as described in Embodiment 3. Through this defrosting device, the refrigerator achieves directional energy output, concentrating energy on the object to be defrosted and improving the defrosting speed.

[0171] Example 5

[0172] This embodiment provides a computer-readable storage medium storing a computer program thereon. When executed by a processor, the computer program implements the defrosting control method as described in Embodiment 1.
