Technical Field

[0001] The utility model relates to the technical field of thawing, in particular to a thawing device and a refrigerator comprising the same. Background Art

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

[0003] There are many forms of thawing technology, such as water thawing, air thawing, microwave thawing and other thawing forms. In thawing technology, the thawing time is usually calculated or the thawing output power is adjusted according to the detected temperature. However, the existing thawing technology still has the problem of inaccurate temperature detection and cannot truly reflect the actual temperature of the frozen food, resulting in the thawing time being too long or too short, the thawing output power being too large or too low, which in turn affects the thawing quality. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the temperature detected during thawing is inaccurate and affects the thawing quality, and to provide a thawing device and a refrigerator including the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A thawing device, comprising a thawing power source and at least one temperature sensor;

[0007] At least one of the temperature sensors is attached to a placement table for placing the object to be thawed, or the temperature sensor extends into the object to be thawed.

[0008] In this solution, the thawing of the object to be thawed is achieved by the power generated by the thawing power source and acting on the object to be thawed. By attaching the temperature sensor to the placement table of the object to be thawed or extending it into the object to be thawed, the temperature of the object to be thawed can be detected close to or directly, which improves the accuracy of the detected temperature and ensures the accuracy of the judgment of the starting temperature, thereby improving the accuracy of reaching the target thawing temperature; at the same time, since the deviation of reaching the target thawing temperature is avoided, the thawing quality of the object to be thawed is improved.

[0009] Preferably, the thawing device comprises a plurality of the temperature sensors, and the plurality of the sensors are evenly distributed on the lower surface of the placement table.

[0010] In this solution, by increasing the number of temperature sensors and evenly distributing them on the lower surface of the placement table, the temperature sensing points are increased, thereby improving the accuracy of temperature detection and the accuracy of detecting the position of the object to be thawed.

[0013] In this solution, the above-mentioned insulation layer and / or insulation material are used to isolate the objects to be thawed and the temperature sensor from the equipment or space outside the placement table, thereby producing a thermal insulation effect, avoiding the influence of the low temperature of the objects to be thawed on other equipment, and ensuring that the temperature detected by the temperature sensor is accurate and not interfered with.

[0014] Preferably, the thawing device further comprises a plurality of pressure sensors, and the plurality of pressure sensors are attached to the lower surface of the placement table and are located at different positions;

[0016] In this solution, by attaching a plurality of pressure sensors to the lower surface of the placement table and located at different positions, the position and weight of the object to be thawed can be accurately identified, thereby improving the accuracy of detecting the position and weight of the object to be thawed. By adjusting the output power and / or output direction of the thawing power source through the pressure signal reflecting the position and weight, it is possible to achieve directional output of energy, improve the concentration of energy, thereby increasing the thawing speed, and avoiding the thawing time being too long or too short due to inaccurate weight detection, thereby ensuring the thawing quality.

[0017] Preferably, the thawing power source is electrically connected to the temperature sensor, and the temperature detected by the temperature sensor is used to adjust the output power and / or output direction of the thawing power source.

[0018] In the present scheme, through the above-mentioned settings, the output power of the thawing power source can be adjusted according to the detected temperature, and the output direction of the thawing power source can be adjusted according to the position of the object to be thawed detected by the temperature sensor. This can achieve directional output of energy and improve the concentration of energy, thereby increasing the thawing speed and avoiding the thawing time being too long or too short due to inaccurately detected temperature, thereby ensuring the thawing quality.

[0019] Preferably, the thawing power source comprises a fan; the fan is electrically connected to the temperature sensor, and the temperature detected by the temperature sensor is used to adjust the speed and / or output wind direction of the fan;

[0021] The thawing power source includes a first heating element, the first heating element is electrically connected to the temperature sensor, and the temperature detected by the temperature sensor is used to adjust the output power and / or output direction of the first heating element.

[0022] In this scheme, through the above-mentioned settings, energy regulation and directional output of energy are achieved through two different technical means (adjusting the fan speed and / or output wind direction, and / or the output power and / or output direction of the heating element), thereby improving the energy concentration and increasing the thawing speed.

[0023] Preferably, the thawing power source comprises a fan; the fan is electrically connected to the temperature sensor, and the temperature detected by the temperature sensor is used to adjust the speed and / or output wind direction of the fan;

[0026] The air guide driving mechanism is electrically connected to the pressure sensor and the temperature sensor, and is used to drive the air guide member to rotate according to the signal detected by the pressure sensor and / or the temperature sensor to adjust the direction of the air outlet of the air guide member relative to the object to be thawed.

[0027] In this solution, the air guide member is driven to rotate by the air guide driving mechanism according to the detected pressure signal and / or temperature signal, thereby realizing a specific structure of directional air blowing, avoiding scattered airflow, and thus increasing the thawing speed.

[0028] Preferably, the thawing power source comprises a second heating element, the second heating element is electrically connected to the temperature sensor, and the temperature detected by the temperature sensor is also used to adjust the output power and / or output direction of the second heating element;

[0029] A heat conducting member is also provided in the box body, and the heat conducting member is attached between the second heating member and the fan.

[0054] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0055] Example 1

[0056] This embodiment provides a thawing device 1, such as Figure 1 and Figure 2 As shown, the thawing device 1 includes a box body 2, a thawing power source 3, a temperature sensor 8, a pressure sensor 9 and other components, and the thawing power source 3, the temperature sensor 8, the pressure sensor 9 and other components are all placed in the box body 2. In this embodiment, the thawing power source 3 specifically includes a fan 4 and a first heating element 5. The object to be thawed 12 (for example: frozen fish) is placed on a placement table 6, and the placement table 6 is specifically a thawing plate, which is placed on the bottom surface of the box body 2 and is separated from the bottom surface of the box body 2 by small spacers at the four corners. Among them, a plurality of temperature sensors 8 are attached to the lower surface of the thawing plate.

[0057] The thawing device 1 attaches the temperature sensor 8 to the placement table 6 for the object to be thawed 12, so that the temperature of the object to be thawed 12 can be detected close to or directly, thereby improving the accuracy of the detected temperature, ensuring the accurate judgment of the starting temperature, thereby improving the accuracy of reaching the target thawing temperature, and achieving controllable thawing end point; at the same time, since the deviation in reaching the target thawing temperature is avoided, the thawing quality of the object to be thawed 12 is improved.

[0058] In other embodiments, according to the type of the object to be thawed and other needs, there are multiple types of thawing power sources, such as microwaves, water vapor, etc., and the thawing power source can be only one or include multiple types. The combination of multiple power sources (such as a combination of blowing and heating) can adapt to more types of objects to be thawed, or, through the combination, the thawing can be accelerated and the quality after thawing can be improved. The placement table can also take other structural forms, or, there is no separate placement table, but the bottom wall of the box is used as a platform for placing the object to be thawed. At this time, the inner wall of the box can be spaced or filled with insulation materials to produce thermal insulation. According to the different types of the placement table, the placement position of the temperature sensor can be on the upper surface of the placement table or on the lower surface. According to the different occasions of the thawing device application, the thawing device may also not have a box, but the various components in the box of the present embodiment are integrated into the equipment (such as a refrigerator) used by the thawing device, and the box is one of the cabins in the applied equipment.

[0059] In other embodiments, depending on the type of the object to be thawed and the type and shape of the temperature sensor, the temperature sensor can also be extended into the object to be thawed (for example, the temperature sensor can be made into a cone, and the bulk object to be thawed can be covered or surrounded by the conical temperature sensor). In this way, the temperature sensor directly contacts the object to be thawed, thereby greatly improving the accuracy of the detected temperature.

[0060] In other embodiments, there may be only one temperature sensor, which is placed on the thawing plate at the center of the object to be thawed. However, this method is not as good as the present embodiment in which multiple sensors are evenly distributed on the lower surface of the thawing plate, increasing the temperature sensing points, thereby improving the accuracy of temperature detection and the accuracy of detecting the position of the object to be thawed 12.

[0061] like Figure 1 As shown, in this embodiment, a heat insulating layer 7 is formed between the thawing plate and the inner wall (i.e., the bottom wall) of the box body 2 relative to the temperature sensor 8 through small spacers at the four corners. At the same time, the outer surface of the thawing plate is wrapped with a heat insulating material. Through the heat insulating layer 7 and the heat insulating material of such a structure, the object to be thawed 12 and the temperature sensor 8 are isolated from the equipment or space outside the thawing plate, producing a thermal insulation effect, avoiding the influence of the low temperature of the object to be thawed 12 on other equipment, and also ensuring that the temperature detected by the temperature sensor 8 is accurate and not disturbed.

[0062] In other embodiments, according to the structural coordination and thawing requirements, thermal insulation may also adopt other insulation means, and there may be one or more insulation measures.

[0063] In this embodiment, the thawing device 1 also includes a control unit (not shown in the figure) and four pressure sensors 9, which are attached to the lower surface of the thawing plate and distributed at the four corners of the thawing plate. The control unit is a circuit board that controls the coordinated work of various electronic components in the box body 2. The thawing power source 3 is electrically connected to the pressure sensor 9 through the control unit. The control unit receives the pressure signal detected by the pressure sensor 9 and sends a signal to the thawing power source 3 to adjust the output power and / or output direction of the thawing power source 3.

[0064] The thawing device 1 can accurately identify the position and weight of the object to be thawed 12 by means of a plurality of pressure sensors 9 attached to the lower surface of the thawing plate and located at different positions, thereby improving the accuracy of detecting the position and weight of the object to be thawed 12. By adjusting the output power and / or output direction of the thawing power source 3 through the pressure signal reflecting the position and weight, it is possible to achieve directional output of energy, improve the concentration of energy, thereby improving the thawing speed, and also avoiding the thawing time being too long or too short due to inaccurate weight detection, thereby ensuring the thawing quality.

[0065] Among them, the thawing power source 3 also establishes an electrical connection with the temperature sensor 8 through the control unit. The temperature detected by the temperature sensor 8 can also be used to adjust the output power and / or output direction of the thawing power source 3, thereby realizing the adjustment of the output power of the thawing power source 3 according to the detected temperature, and adjusting the output direction of the thawing power source 3 according to the position of the object to be thawed 12 detected by the temperature sensor 8. It can also realize directional output of energy, improve the concentration of energy, thereby improving the thawing speed, and avoiding the thawing time being too long or too short due to inaccurately detected temperature, thereby ensuring the thawing quality.

[0066] As mentioned above, in this embodiment, since the thawing power source 3 includes a fan 4 and a first heating element 5, the first heating element 5 is specifically a heating plate. The fan 4 and the first heating element 5 are electrically connected to the temperature sensor 8 through the control unit, and the temperature detected by the temperature sensor 8 can be used to adjust the speed and / or output wind direction of the fan 4, and can also be used to adjust the output power and / or output direction of the first heating element 5. Similarly, the pressure signal can also be used to adjust the speed and / or output wind direction of the fan 4, and can also be used to adjust the output power and / or output direction of the first heating element 5.

[0067] Through the above-mentioned arrangement, the thawing device 1 realizes energy regulation and directional output of energy through two different technical means (adjusting the rotation speed and / or output wind direction of the fan 4, and / or the output power and / or output direction of the heating element), thereby improving the concentration of energy and increasing the thawing speed.

[0068] In other embodiments, the control unit can select an object to be adjusted as needed, that is, adjust the fan 4 or the first heating element 5, or adjust both.

[0069] like Figure 1 As shown, a fan cover 11 is also provided in the box body 2, and a first heating element 5, a heat conducting element 13, a fan 4, a plurality of air guides 10 and an air guide driving mechanism (not shown in the figure) are provided in the fan cover 11. The heat conducting element 13 is specifically a heat conducting block, and the first heating element 5 is closely attached to the plane of the heat conducting element 13, and the fins of the heat conducting element 13 are closely attached to the air inlet surface of the fan 4, and the air outlet of the fan 4 faces downward. The air guide 10 is specifically a sheet-shaped air guide, which is arranged at a position of the fan cover 11 relative to the fan 4 and is rotatably connected to the fan cover 11. The air guide driving mechanism is electrically connected to the pressure sensor 9 and the temperature sensor 8 through the control unit, and the air guide driving mechanism is used to drive the air guide 10 to rotate according to the signal detected by the pressure sensor 9 and / or the temperature sensor 8, so as to adjust the direction of the air outlet of the air guide 10 relative to the object to be thawed 12.

[0070] The thawing device 1 concentrates the heated airflow into the space inside the fan cover 11 through the fan cover 11 to avoid heat dissipation; the air guide driving mechanism drives the air guide member 10 to rotate according to the detected pressure signal and / or temperature signal, and then blows the heat to the surface of the to-be-thawed object 12 in a direction through the air guide member 10, thereby realizing the specific structure of directional blowing, avoiding scattered airflow, and improving the thawing speed.

[0071] In other embodiments, depending on the specific structure, the thawing device may not have a separate fan cover, and the fan may be embedded in the inner wall of the box, the inner wall of the box is used as the fan cover, and the air guide is placed on the inner wall of the box. Alternatively, the fan cover may also be a part of the fan housing.

[0072] In this embodiment, the thawing process is accelerated by the first heating element 5 on the basis of directional blowing. The heat transfer capacity of the first heating element 5 is improved by the heat conducting element 13, and the heat is quickly integrated into the air and blown to the object 12 to be thawed by the fan 4.

[0073] In other embodiments, the thawing power source 3 may also include multiple heating elements, and different heating elements may be used for heating at different positions or under different working conditions, and some heating elements may be selected to work as needed. For example, a second heating element is added, and the second heating element, like the first heating element 5, may also be electrically connected to the temperature sensor 8 through the control unit, and the temperature detected by the temperature sensor 8 is also used to adjust the output power and / or output direction of the second heating element.

[0074] like Figure 2As shown, a plurality of small through holes 14 are provided on the side of the fan cover 11, and the fan 4 blows the first heating element 5 to generate heat to form hot air, which is directed by the air guide 10 and blown to the surface of the object to be thawed 12 along the gas flow direction A, and then the airflow flows back to the fan cover through the through holes 14 along the gas flow direction A and is heated by the first heating element 5. The hot airflow circulates back and forth continuously to raise the temperature of the object to be thawed 12 to the target temperature, and the thawing is completed.

[0075] Example 2

[0076] The present embodiment provides a refrigerator, which includes a thawing device 1 as in Embodiment 1. The refrigerator can detect the temperature of the object to be thawed 12 by attaching a temperature sensor 8 to the thawing plate of the object to be thawed 12 or extending the temperature sensor 8 into the object to be thawed 12, thereby improving the accuracy of the temperature detection, ensuring the accuracy of the judgment of the starting temperature, and thus improving the accuracy of reaching the target thawing temperature; at the same time, since the deviation of reaching the target thawing temperature is avoided, the thawing quality of the object to be thawed 12 is improved.

[0077] In other embodiments, depending on different applications, the thawing device 1 of Example 1 can also be used for other equipment that needs to be thawed, and is not limited to just refrigerators.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
