Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0052] Figure 1 is a schematic structural diagram of a clamping device according to an embodiment of the present invention, as Figure 1 shown, and with reference to Figures 2 to 6 , an embodiment of the present invention provides a clamping device for thawing, including a mounting portion, a plurality of heat-conducting needles, and a driving portion. The heat-conducting needles are mounted on the mounting portion, and the plurality of heat-conducting needles are individually used to clamp an object to be thawed. And the tips of the plurality of heat-conducting needles are all used to pierce into the object to be thawed. The driving portion drives the heat-conducting needles to pierce into the object to be thawed.

[0053] In this embodiment, the clamping device clamps the object to be thawed, so that the heat conduction needles penetrate into the object to be thawed. The temperature outside the object to be thawed is transmitted into the interior of the object to be thawed through the heat conduction needles, so that the interior of the object to be thawed comes into contact with the external temperature, thereby increasing the thawing speed inside the object to be thawed. This thawing method saves the cost of thawing treatment. Moreover, compared with the natural thawing method from the outside to the inside, it avoids the situation of uneven thawing. There will be no problem that after the surface layer of the object to be thawed has melted for a long time, the central part is still difficult to cut, and more time is needed to wait for the internal thawing, thus improving the thawing efficiency.

[0054] In some alternative embodiments of the present invention, a plurality of heat conduction needles cooperate with the mounting portion to clamp the object to be thawed.

[0055] In some alternative embodiments of the present invention, the mounting portion is used alone to clamp the object to be thawed.

[0056] In some embodiments of the present invention, the driving portion includes a power storage device, and the power storage device is configured to release the stored power to cause a plurality of heat conduction needles to penetrate into the object to be thawed based on the self-thawing change of the object to be thawed.

[0057] In this embodiment, the object to be thawed is installed in the clamping device, and the power storage device obtains the stored power. As the object to be thawed undergoes self-thawing changes, the stored power of the power storage device is released, so that the tips of the plurality of heat conduction needles penetrate into the object to be thawed along with the released stored power. It is not necessary to apply an external force separately to make the heat conduction needles penetrate into the object to be thawed, which simplifies the operation steps of thawing.

The plurality of heat conduction needles include a plurality of first heat conduction needles 110, and the plurality of first heat conduction needles 110 are arranged on the other side of the object to be thawed.

[0059] In this embodiment, the first clamping plate 210 and the first heat conduction needles 110 cooperate to clamp the object to be thawed. As the object to be thawed thaws, the first heat conduction needles 110 penetrate from the surface of the object to be thawed into the interior of the object to be thawed, and the temperature outside the object to be thawed is transmitted into the interior through the first heat conduction needles 110 to thaw the interior of the object to be thawed.

[0061] In this embodiment, the object to be thawed is clamped by the first clamping plate 210 and the first heat conduction needles 110 arranged on the second clamping plate 220. As the object to be thawed thaws, the first heat conduction needles 110 penetrate from the surface of the object to be thawed into the interior of the object to be thawed, and transfer the temperature outside the object to be thawed into the interior through the first heat conduction needles 110, so as to thaw the interior of the object to be thawed.

[0063] In this embodiment, the object to be thawed is clamped by the second heat conduction needles 120 arranged on the first clamping plate 210 and the first heat conduction needles 110 arranged on the second clamping plate 220. As the object to be thawed thaws, the first heat conduction needles 110 and the second heat conduction needles 120 penetrate from the surfaces on both sides of the object to be thawed into the interior of the object to be thawed, and transfer the temperature outside the object to be thawed into the interior through the first heat conduction needles 110 and the second heat conduction needles 120, so as to thaw the interior of the object to be thawed, making the thawing speed of the object to be thawed faster and the thawing efficiency higher.

[0064] As Figure 2 shown, in some embodiments of the present invention, the driving part is connected to the second clamping plate 220.

[0065] In this embodiment, take the clamping device including the first clamping plate 210, the second clamping plate 220 and the first heat conduction needles 110 as an example. Since the first clamping plate 210 is located on one side of the object to be thawed, the second clamping plate 220 is located on the other side of the object to be thawed and the first heat conduction needles 110 are arranged on the second clamping plate 220, the driving part drives the second clamping plate 220 to move, so that the heat conduction needles penetrate into the object to be thawed.

[0066] In some other embodiments of the present invention, the driving part is connected to the first clamping plate 210.

[0067] In this embodiment, take the clamping device including the first clamping plate 210, the second clamping plate 220 and the first heat conduction needles 110 as an example. Since the first clamping plate 210 is located on one side of the object to be thawed and the first heat conduction needles 110 are located on the other side of the object to be thawed, the driving part drives the first clamping plate 210 to move, so that the first clamping plate 210 moves towards the other side of the object to be thawed, pushing the object to be thawed towards the direction of the first heat conduction needles 110, so that the first heat conduction needles 110 penetrate into the object to be thawed.

[0068] In some other embodiments of the present invention, the driving part is connected to the first clamping plate 210 and the second clamping plate 220.

[0069] In this embodiment, take the clamping device including the first clamping plate 210, the second clamping plate 220, the first heat conduction needle 110 and the second heat conduction needle 120 as an example. Since the first clamping plate 210 is located on one side of the object to be thawed, the second clamping plate 220 is located on the other side of the object to be thawed, and the second heat conduction needle 120 is provided on the first clamping plate 210, and the first heat conduction needle 110 is provided on the second clamping plate 220, the driving part drives the first clamping plate 210 and the second clamping plate 220 to move, so that the first heat conduction needle 110 and the second heat conduction needle 120 penetrate into the object to be thawed.

[0070] Alternatively, in some other embodiments of the present invention, the driving part is connected to a plurality of heat conduction needles.

[0071] In this embodiment, the driving part directly drives a plurality of heat conduction needles to penetrate into the object to be thawed.

[0072] In some embodiments of the present invention, the first clamping plate 210 is a heat conduction plate.

[0073] In this embodiment, the second heat conduction needle 120 is arranged on the first clamping plate 210, and the heat conduction plate transfers heat to the plurality of second heat conduction needles 120. The plurality of second heat conduction needles 120 not only facilitate the rapid thawing of the inside of the object to be thawed, but also make the inside of the object to be thawed evenly heated.

[0074] Alternatively, in some other embodiments of the present invention, the second clamping plate 220 is a heat conduction plate.

[0075] In this embodiment, the first heat conduction needle 110 is arranged on the second clamping plate 220, and the heat conduction plate transfers heat to the plurality of first heat conduction needles 110. The plurality of first heat conduction needles 110 not only facilitate the rapid thawing of the inside of the object to be thawed, but also make the inside of the object to be thawed evenly heated.

[0076] Alternatively, in some other embodiments of the present invention, both the first clamping plate 210 and the second clamping plate 220 are heat conduction plates.

[0077] In this embodiment, compared with having a heat conduction plate only on one side, the first heat conduction needle 110 is arranged on the second clamping plate 220, and the second heat conduction needle 120 is arranged on the first clamping plate 210. The heat conduction plate transfers heat to the plurality of first heat conduction needles 110 and the plurality of second heat conduction needles 120. Both the plurality of first heat conduction needles 110 and the plurality of second heat conduction needles 120 are beneficial to rapidly thaw the inside of the object to be thawed, and the plurality of first heat conduction needles 110 and the plurality of second heat conduction needles 120 can make the inside of the object to be thawed more evenly heated.

[0078] In some embodiments of the present invention, the clamping device for thawing further includes a probe thermometer 500, and the probe thermometer 500 is installed on the installation part. The driving part is also used to cause the probe thermometer 500 to penetrate into the object to be thawed.

[0079] In this embodiment, the probe thermometer 500 is inserted into the object to be thawed to measure the temperature inside the object to be thawed, so as to adjust the thawing temperature, making the thawing effect better and improving the thawing efficiency.

[0080] In some embodiments of the present invention, the probe thermometer 500 moves synchronously with the heat conduction needle.

[0081] In this embodiment, the probe thermometer 500 moves together with the heat conduction needle to monitor the temperature inside the object to be detected in real time, enabling timely feedback on temperature adjustment and more accurate control of the thawing temperature.

[0082] As Figure 2 or Figure 3 shown, in some embodiments of the present invention, the detection point of the probe thermometer 500 is on the same plane as the tips of multiple heat conduction needles.

[0083] In this embodiment, the probe thermometer 500 moves together with the heat conduction needle and is on the same plane as the tip of the heat conduction needle to monitor the temperature of the plane where the heat conduction needle is located inside the object to be detected in real time, so as to adjust the thawing temperature according to the monitored temperature of the plane where the heat conduction needle is located inside the object to be detected.

[0084] As Figure 2 or Figure 3 shown, in some embodiments of the present invention, the probe thermometer 500 is arranged on the second clamping plate 220.

[0085] In this embodiment, the first heat conduction needle 110 is arranged on the second clamping plate 220. The probe thermometer 500 is arranged on the second clamping plate 220, on the same side as the first heat conduction needle 110. As the first heat conduction needle 110 penetrates deeper, the probe thermometer 500 moves together with the first heat conduction needle 110 to monitor the temperature on the same plane inside the object to be thawed where the first heat conduction needle 110 is located in real time.

[0086] In some other embodiments of the present invention, the probe thermometer 500 is arranged on the first clamping plate 210.

[0087] In this embodiment, the second heat conduction needle 120 is arranged on the first clamping plate 210. The probe thermometer 500 is arranged on the first clamping plate 210, on the same side as the second heat conduction needle 120. As the second heat conduction needle 120 penetrates deeper, the probe thermometer 500 moves together with the second heat conduction needle 120 to monitor the temperature on the same plane inside the object to be thawed where the second heat conduction needle 120 is located in real time.

[0088] In some other embodiments of the present invention, the probe thermometer 500 is arranged on both the first clamping plate 210 and the second clamping plate 220.

[0089] In this embodiment, a second heat conduction needle 120 is provided on the first clamping plate 210, a first heat conduction needle 110 is provided on the second clamping plate 220, a probe thermometer 500 is provided on the first clamping plate 210, on the same side as the second heat conduction needle 120, and another probe thermometer 500 is provided on the second clamping plate 220, on the same side as the first heat conduction needle 110. As the heat conduction needle penetrates deeper, the probe thermometer 500 moves together with the heat conduction needle to monitor in real time the temperature on the same plane inside the object to be thawed where the first heat conduction needle 110 and the second heat conduction needle 120 are located. As Figure 3 shown, an embodiment of the present invention provides a thawing device, including a clamping device, and the clamping device is the thawing clamping device of any one of the above embodiments.

[0090] In this embodiment, taking the clamping device including a first clamping plate 210, a second clamping plate 220, a first heat conduction needle 110, and a second heat conduction needle 120 as an example. A plurality of second heat conduction needles 120 on the first clamping plate 210 and a plurality of first heat conduction needles 110 on the second clamping plate 220 clamp the object to be thawed. As the surface of the object to be thawed thaws, the plurality of first heat conduction needles 110 and the plurality of second heat conduction needles 120 penetrate into the object to be thawed, and the temperature outside the object to be thawed is transmitted into the object to be thawed through the plurality of first heat conduction needles 110 and the plurality of second heat conduction needles 120, so that the inside of the object to be thawed contacts the external temperature, and the thawing speed inside the object to be thawed is increased. This thawing method saves the cost of thawing treatment, and compared with the natural thawing method from the outside to the inside, it avoids the situation of uneven thawing, and there will be no problem that after the surface layer of the object to be thawed melts for a long time, the central part is still very difficult to cut, and more time is needed to wait for the internal thawing, thus improving the thawing efficiency.

[0091] In some embodiments of the present invention, the thawing device thaws the object to be thawed through a medium, and the thawing device further includes a cold source, a heat source, a mixing device, and a controller. The cold source provides cold quantity to the medium. The heat source provides heat to the medium. The medium is a fluid medium. The mixing device is configured to mix the fluid medium after heat exchange with the cold source and the heat source, so that the mixed fluid medium exchanges heat with the object to be thawed. The controller is configured to control the amount of cold quantity released by the cold source and the amount of heat released by the heat source to control the temperature of the mixed fluid medium.

[0092] In this embodiment, the fluid medium can be an air flow. The cold source provides cold quantity to the air flow, and the heat source provides heat to the air flow. The hot air flow and the cold air flow are mixed in the mixing device. The controller can make the temperature of the air flow variable by adjusting the amount of cold quantity released by the cold source and the amount of heat released by the heat source, so that the temperature of the air flow is the preset thawing temperature. Of course, it can also be configured to other temperatures. The mixed air flow exchanges heat with the object to be thawed, transfers heat to the object to be thawed, increases the temperature of the object to be thawed or thaws the object to be thawed. Compared with only having a single cold source or a single heat source, by mixing the cold source and the heat source, the temperature adjustment is more accurate.

[0093] In some embodiments of the present invention, the mixing device includes an air flow machine. First, hot air flow and cold air flow are mixed, and after mixing, they are blown out by the air flow machine. After the mixed air flow exchanges heat with the object to be thawed, the air flow exchanges heat with the cold source and the heat source again. The recycling and reuse of the fluid medium air flow are realized.

[0094] Furthermore, in some embodiments of the present invention, the controller is configured to control the amount of cold released by the cold source and the amount of heat released by the heat source according to the temperature inside the object to be thawed, so as to control the temperature of the mixed medium.

[0095] In this embodiment, the probe thermometer 500 is inserted into the object to be thawed along with the heat conduction needle to monitor the temperature inside the object to be thawed. According to this temperature, the temperature of the mixed medium is adjusted through the controller. Adjusting the thawing temperature according to the temperature inside the object to be thawed can more precisely control the thawing temperature, prevent the surface of the object to be thawed from melting too fast due to too high a temperature, resulting in the loss of surface juice, or prevent the thawing time from being too long and the thawing efficiency from being low due to too low a temperature.

[0096] As Figure 3 shown, in some embodiments of the present invention, the thawing device includes a first opening 700, and the first opening 700 is connected to the outside. The outside air flow passes through the cold source and the heat source, mixes the hot air flow and the cold air flow in the mixing device, and then is blown out through the first opening 700 to exchange heat with the object to be thawed, and then the air flow after heat exchange is discharged into the outside.

[0097] In some other embodiments of the present invention, the thawing device includes a first opening and a second opening. The first opening and the second opening are connected by a duct, and the first opening, the mixing device, the cold source, and the heat source are arranged in sequence along the duct.

[0098] In this embodiment, the air flow enters the second opening, passes through the cold source or the heat source respectively to become cold air flow or hot air flow, mixes the hot air flow and the cold air flow in the mixing device, and then is blown out through the first opening to exchange heat with the object to be thawed. After the mixed air flow exchanges heat with the object to be thawed, it enters the second opening again to realize the circulation of the air flow.

[0099] As Figure 2 or Figure 3 shown, in some embodiments of the present invention, the thawing device further includes a distance sensor 400, and the distance sensor 400 is configured to monitor the moving distance of the heat conduction needle.

[0100] In this embodiment, the moving distance of the heat conduction needle is monitored by the distance sensor 400, and thus the thawing condition of the object to be thawed is monitored. Moreover, the signal can be fed back to the controller according to the thawing condition of the object to be thawed to change the thawing temperature and ensure the thawing efficiency.

[0101] Preferably, the distance sensor 400 can be a laser rangefinder.

[0102] Preferably, the heat conduction needle is vertically arranged, and the distance sensor 400 is arranged directly above the heat conduction needle.

[0103] An embodiment of the present invention provides a refrigerator 600 including the thawing device in any one of the above embodiments.

[0104] In this embodiment, the refrigerator 600 is equipped with a thawing device, which facilitates directly putting the object to be thawed into the thawing device after taking out the object to be thawed. Moreover, since the thawing device uses a clamping device to clamp the object to be thawed, so that the heat conduction needle penetrates into the object to be thawed, the temperature outside the object to be thawed is transmitted into the object to be thawed through the heat conduction needle, thereby enabling the inside of the object to be thawed to contact the external temperature, and improving the thawing speed inside the object to be thawed. This thawing method saves the cost of thawing treatment, and compared with the natural thawing method from the outside to the inside, it avoids the situation of uneven thawing. There will be no problem that after the surface layer of the object to be thawed has melted for a long time, the central part is still very difficult to cut, and more time is needed to wait for the internal thawing, thus improving the thawing efficiency.

[0105] As Figure 4 shown, in some embodiments of the present invention, the refrigerator 600 further includes a thawing drawer 610, and the thawing device is installed in the thawing drawer 610.

[0106] In this embodiment, the thawing device is installed in the thawing drawer 610, and a rotatable drawer cover is provided on the front side of the thawing drawer 610, which is convenient for the user to open the drawer cover in time to put the object to be thawed when the user needs to thaw the object to be thawed, and the operation is simple.

[0107] In some embodiments of the present invention, the thawing drawer 610 is located in the refrigerating space of the refrigerator 600, so that the temperature in the thawing drawer 610 is lower than the external temperature, making the original temperature in the drawer closer to the thawing temperature. It does not require too much cooling capacity to make the temperature in the thawing drawer reach the thawing temperature for thawing, saving energy, and thus reducing the usage cost.

[0108] As Figure 2 or Figure 3 shown, in some embodiments of the present invention, the energy storage device is a spring 300. One end of the spring 300 is connected to the second clamping plate 220, and the other end of the spring 300 is connected to the inner wall of the thawing device, and of course, it can also be connected to the inner wall of the drawer. The first clamping plate 210 is fixedly connected to the inner wall of the drawer.

[0109] As Figure 5 shown, an embodiment of the present invention also provides a thawing method for the thawing device in any one of the above embodiments. The thawing device thaws the object to be thawed through a medium, and the thawing method includes:

[0110] Step S1: Monitor the depth of penetration of the heat conduction needle.

[0111] Step S2: After the distance changes by a set distance, lower the temperature of the medium to the first thawing temperature.

[0112] Step S3: Measure the temperature of the surface where the tip of the heat conduction needle is located inside the object to be thawed.

[0113] Step S4: When it is detected that the temperature is lower than the set temperature, raise the temperature of the medium to the second thawing temperature.

[0114] In this embodiment, when the distance sensor 400 monitors that the heat conduction needle moves a set distance, it transmits a signal to the controller to lower the temperature of the medium to the first thawing temperature, so as to reduce the juice loss caused by excessive thawing on the surface of the object to be thawed. Preferably, the set distance is 2 mm. As the heat conduction needle penetrates, when the probe thermometer 500 monitors that the temperature is lower than the set temperature, it transmits a signal to the controller to raise the temperature of the medium to the second thawing temperature, so as to increase the thawing speed. This thawing method saves the cost of thawing treatment, and compared with the natural thawing method from the outside to the inside, it avoids the situation of uneven thawing. There will be no problem that after the surface layer of the object to be thawed melts for a long time, the central part is still difficult to cut and more time is needed to wait for the internal thawing, thus improving the thawing efficiency.

[0115] Further, steps S1 to S4 can be cycled multiple times until the probe thermometer 500 monitors that the internal temperature of the object to be thawed is the first thawing temperature, that is, the thawing is completed.

[0116] Preferably, the set temperature is the freezing point temperature; when the object to be thawed is meat, the set temperature is -5°C, and the second thawing temperature is 0 to 5°C higher than the first thawing temperature. This can accelerate the thawing inside the thawed object while ensuring that the surface of the object to be thawed is not overly thawed.

[0117] Further, in some embodiments of the present invention, the first thawing temperature is lower than or equal to the freezing point temperature of the object to be thawed.

[0118] In this embodiment, compared with adjusting to a temperature higher than the freezing point temperature of the object to be thawed, adjusting the temperature to be lower than or equal to the freezing point temperature of the object to be thawed can effectively reduce the juice loss caused by excessive thawing on the surface of the object to be thawed.

[0119] As Figure 6 shown, in some embodiments of the present invention, before monitoring the depth of penetration of the heat conduction needle, the thawing method for the thawing device further includes:

[0120] Step S5: After the clamping device clamps the object to be thawed, set the temperature of the medium to the third thawing temperature. The third thawing temperature is higher than the second thawing temperature and higher than the freezing point temperature of the object to be thawed.

[0121] In this embodiment, the third thawing temperature is higher than the second thawing temperature and higher than the freezing point temperature of the object to be thawed. Setting the temperature of the medium to the third thawing temperature can increase the thawing speed on the surface of the object to be thawed, thereby improving the overall thawing efficiency. Preferably, the third thawing temperature is 5 to 10 °C higher than the first thawing temperature.

[0122] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
