[0048] Embodiment 1

[0049] The rapid thawing of the object to be thawed has always been a challenge in the field of cryogenic storage. Traditional thawing methods usually require a large amount of time, especially for large and deeply frozen objects to be thawed. This may lead to problems such as a decline in the quality of the object to be thawed and the growth of bacteria.

[0050] To solve this problem, existing thawing devices achieve the function of rapid thawing by setting heating wires at the upper part of the thawing chamber. However, when thawing, the object to be thawed is generally placed at the bottom of the thawing chamber, and this thawing device cannot effectively heat the bottom of the object to be thawed, resulting in uneven thawing.

[0051] In view of the problem that the thawing device in the prior art cannot effectively heat the bottom of the object to be thawed, resulting in uneven thawing, this embodiment provides a thawing device. Figure 1 As shown in the structure diagram of the thawing device according to an embodiment of the present invention, Figure 1 As shown, the above-mentioned thawing device includes: a thawing chamber 1; a first heating wire 2, arranged at the top of the thawing chamber 1, for heating the upper surface of the object to be thawed through the first heating wire 2; a semiconductor refrigeration plate 3, with its hot end arranged at the bottom of the thawing chamber 1 and its cold end arranged outside the thawing chamber 1; a circulating air duct 4, with its inlet arranged around the first heating wire 2 and its outlet arranged at the bottom of the thawing chamber 1; and a fan 5, arranged in the circulating air duct 4.

[0052] When the thawing device provided in the above embodiment is applied, the object to be thawed is generally placed at the bottom of the thawing chamber 1. Due to the characteristic that hot air rises, if a circulating device is not added, the hot air will always accumulate at the top of the thawing chamber 1 and will not spread downward, resulting in only the upper surface of the object to be thawed being heated and the heating being uneven. The setting of the circulating air duct and the fan 5 is to spread the heat generated by the first heating wire 2 to the entire internal space of the thawing chamber 1, so that the temperature in the internal space of the thawing chamber 1 is balanced. Further, the hot air is diffused downward to the bottom of the thawing chamber 1 to achieve comprehensive, balanced and uniform thawing of the object to be thawed. By driving the air flow in the circulating air duct 4 by the fan 5, the hot air around the first heating wire 2 is diffused to the bottom of the thawing chamber 1 to heat the side surface of the object to be thawed at the bottom of the thawing chamber, making the object to be thawed heated evenly and accelerating the thawing.

[0053] In addition, a semiconductor refrigeration plate 3 is arranged at the bottom of the thawing chamber 1, and the bottom surface of the object to be thawed is heated through the hot end of the semiconductor refrigeration plate 3 to further improve the uniformity of heating of the object to be thawed.

[0054] For the thawing device of this embodiment, a first heating wire 2 is arranged at the upper part of the thawing chamber to heat the upper surface of the object to be thawed; a circulating air duct 4 and a fan 5 are arranged, and the air flow in the circulating air duct 4 is driven by the fan 5 to spread the hot air around the first heating wire 2 to the bottom of the thawing chamber 1 to heat the side surface of the object to be thawed; the bottom surface of the object to be thawed is heated through the hot end of the semiconductor refrigeration plate 3. Through the above solutions, heating of all surfaces of the object to be thawed can be realized, the uniformity of heating of the object to be thawed can be improved, and thus the thawing efficiency and the overall thawing effect can be improved.

[0055] Figure 2 As shown in the structure diagram of the semiconductor refrigeration plate according to an embodiment of the present invention, Figure 2 As shown, the above-mentioned semiconductor refrigeration plate 3 includes: a plurality of semiconductor refrigeration chips 31, and the semiconductor refrigeration chips 31 are evenly distributed on the semiconductor refrigeration plate 3.

[0056] Figure 3 Internal structure diagram of a semiconductor refrigeration sheet according to an embodiment of the present utility model, as Figure 3 shown, the semiconductor refrigeration sheet includes:

[0057] A plurality of thermocouples connected in series, wherein each thermocouple includes an N-type semiconductor 31a, a current conducting bar 31b, and a P-type semiconductor 31c.

[0058] A cold end and a hot end. In order to achieve an insulating effect and avoid electric leakage, a cold end electrical insulation layer 31d is provided at the cold end, and a hot end electrical insulation layer 31e is provided at the hot end. Both the cold end electrical insulation layer 31d and the hot end electrical insulation layer 31e are made of a heat-conducting insulating material, which has a heat-conducting effect while achieving the insulating effect, facilitating the transfer of cold or heat.

[0059] A DC power supply 31f; its positive pole is connected to the N-type semiconductor 31a of the first thermocouple, and its negative pole is connected to the P-type semiconductor 31c of the last thermocouple, for supplying power to a plurality of thermocouples connected in series.

[0060] It should be noted that in other embodiments of the present utility model, the connection form of a plurality of thermocouples can also be in parallel.

[0061] In order to further improve the temperature uniformity and thawing efficiency, the inner wall of the thawing chamber is made of an alloy material. This alloy has excellent heat-conducting characteristics, which helps to quickly conduct temperature to ensure a uniform and efficient thawing process.

[0062] When heating a large-volume and heavy object to be thawed, the heat provided by one heating wire is often insufficient. In order to improve the heating effect, the above-mentioned thawing device further includes: a second heating wire 6, which is arranged at the top or side of the thawing chamber 1. In this embodiment, it is arranged at the top of the thawing chamber 1 for auxiliary heating. The heating power of the second heating wire 6 is less than that of the first heating wire 2, that is, the first heating wire 2 is the main heating wire and the second heating wire 6 is the auxiliary heating wire. In specific implementation, according to the weight range of the object to be thawed, the second heating wire 6 and the semiconductor refrigeration plate 3 can be controlled to be turned on simultaneously, the first heating wire 2 and the semiconductor refrigeration plate 3 can be controlled to be turned on simultaneously, or the first heating wire, the second heating wire 6 and the semiconductor refrigeration plate 3 can be controlled to be turned on simultaneously.

[0063] Since heating is required during the thawing process, it will cause water loss of the object to be thawed and the taste will deteriorate. In order to prevent the object to be thawed from being over-thawed and dehydrated, the thawing device further includes: a humidifier, which is arranged in the thawing chamber. The humidifier includes: a water storage box 7 for storing liquid water; a water delivery pipe 8, whose water inlet is connected to the water storage box 7 and whose water outlet is connected to an atomizing nozzle 9; the atomizing nozzle 9 is arranged at the upper part of the thawing chamber and is used to atomize the liquid water in the water storage box 7 and diffuse it into the thawing chamber 1. On the one hand, the humidity is controlled by the humidifier to ensure that the object to be thawed maintains an appropriate water content, thereby improving the quality of the object to be thawed; on the other hand, after the object to be thawed is taken out, the water output of the humidifier can be increased to flush and clean the blood in the thawing chamber.

[0064] In order to maintain the dryness and cleanliness in the thawing chamber 1 and avoid water accumulation and moisture retention, the above-mentioned thawing device further includes: a drain pipe 10, whose water inlet is arranged at the bottom of the thawing chamber 1 and whose water outlet is arranged outside the thawing chamber. The water generated during thawing and the water during the humidification process are quickly discharged from the thawing chamber through the drain pipe 10.

[0065] In order to detect the weight of the object to be thawed in the thawing chamber 1, the above-mentioned thawing device further includes: a weight sensor 11, which is arranged at the bottom of the thawing chamber 1. On the one hand, it helps the system determine whether an object to be thawed is placed in the thawing chamber so as to start the thawing device when needed; on the other hand, different thawing powers can be selected according to the size of the object to be thawed in order to achieve the purpose of energy saving.

[0066] In order to monitor the temperature at the bottom of the object to be thawed in real time and thus ensure that the temperature around the object to be thawed tends to be relatively uniform, the above-mentioned thawing device further includes: a temperature sensor 12, which is arranged at the bottom of the thawing chamber.

[0067] In order to detect the temperature and humidity data in the thawing chamber 1 in real time and thus determine whether it is necessary to replenish water through the humidifier, the above-mentioned thawing device further includes: a humidity sensor 13, which is arranged at any position inside the thawing chamber.

[0068] In order to facilitate opening and closing, a handle 14 is arranged on the thawing chamber.

[0069] Figure 4 For the electrical control schematic diagram according to the embodiment of the present invention, as Figure 4 shown, the controller 410 is respectively connected to the sensor module 420, the humidifier 430 and the heating module 440. Among them, the sensor module 420 includes a weight sensor 11, a temperature sensor 12 and a humidity sensor 13, and the heating module 430 includes a first heating wire 2, a semiconductor refrigeration plate 3 and a second heating wire 6.

[0070] The controller 410 controls the simultaneous activation of the second heating wire 6 and the semiconductor refrigeration plate 3, the simultaneous activation of the first heating wire 2 and the semiconductor refrigeration plate 3, or the simultaneous activation of the first heating wire, the second heating wire 6, and the semiconductor refrigeration plate 3 according to the weight data collected by the weight sensor 11.

[0071] The controller 410 controls the activation or deactivation of the humidifier 430 according to the humidity data collected by the humidity sensor 13.

[0072] The controller 410 controls the rotational speed of the blower 5 and the partial or full activation of the first heating wire 2 and the second heating wire 6 according to the temperature data collected by the temperature sensor 12.

[0073] This embodiment employs a series of key components to achieve an efficient thawing process. The following is a detailed description of these components:

[0074] Alloy thawing chamber with good thermal conductivity: The inner wall of the thawing chamber is made of an alloy with good thermal conductivity. This alloy has excellent heat conduction characteristics, which helps to quickly conduct temperature to ensure a uniform and efficient thawing process.

[0075] Humidity sensor: A temperature and humidity sensor is built into the inner wall of the thawing chamber to detect the humidity data inside the thawing chamber in real time. These sensors provide the necessary information for the system to make adjustments according to the needs of different items to be thawed.

[0076] Temperature sensor: A high-precision temperature sensor is configured at the bottom of the thawing chamber to monitor the temperature at the bottom of the item to be thawed in real time during thawing. The controller can compare the temperature data it feeds back with the temperature data transmitted by the temperature and humidity sensor, and by controlling the activation and stop of the semiconductor refrigeration plate, or regulating its voltage and current to dynamically adjust the heat generated by the semiconductor refrigeration plate, it can control the temperatures of both within a certain range, thereby making the temperature around the item to be thawed tend to be relatively uniform.

[0077] Weight sensor: A weight sensor is installed at the bottom of the thawing chamber to sense the item to be thawed. According to the detected weight information, the system will automatically select the corresponding thawing mode (low power consumption mode, normal power consumption mode, ultra power consumption mode). On the one hand, it helps the system determine the situation of the item to be thawed in the thawing chamber to initiate the thawing process when needed; on the other hand, it can select different thawing modes according to the size of the item to be thawed to achieve the purpose of energy conservation.

[0078] Humidifier: The humidifier located inside the thawing chamber is used to prevent the item to be thawed from being over-thawed and dehydrated. On the one hand, by controlling the humidity, the humidifier ensures that the item to be thawed maintains an appropriate moisture content, thereby improving the quality of the item to be thawed; on the other hand, after the item to be thawed is taken out, the water output of the humidifier can be increased to flush and clean the blood in the thawing chamber.

[0079] Thermoelectric cooler: It is composed of multiple thermocouples connected in series or parallel. When an electric current passes through a thermocouple, one end absorbs heat and the other end releases heat. Thermoelectric cooling utilizes this characteristic to achieve the purpose of refrigeration. The thermoelectric cooler includes a number of thermocouples connected in series. Each thermocouple includes an N-type semiconductor, a current-carrying bar, and a P-type semiconductor. The thermoelectric cooler also has a cold end and a hot end. To achieve insulation and prevent electric leakage, a cold-end electrical insulation layer is provided at the cold end, and a hot-end electrical insulation layer is provided at the hot end. The P-type semiconductor and the N-type semiconductor are welded to the current-carrying bar, and the current-carrying bar is fixed in the electrical insulation layer. When direct current is applied, the current at the upper end of the thermocouple flows from the N-type semiconductor to the P-type semiconductor, so the temperature at the upper end drops and becomes the cold end; the current at the lower end of the thermocouple flows from the P-type semiconductor to the N-type semiconductor, and the temperature at the lower end rises and becomes the hot end. In this proposal, a thermoelectric cooling plate composed of thermoelectric coolers is provided at the bottom of the thawing chamber. By controlling its start / stop or adjusting the voltage and current, the heat generated for thawing is regulated to provide temperature compensation for the bottom of the object to be thawed, avoiding insufficient heating at the bottom of the object to be thawed. On the other hand, during the thawing mode, the cold end can provide a part of the cooling capacity for the freezer for refrigeration.

[0080] Heating device: It includes a main heating wire and an auxiliary heating wire. The main heating wire and the auxiliary heating wire are responsible for controlling the temperature to meet the requirements of different objects to be thawed.

[0081] Circulation system: It includes a fan and an air duct. The fan is used to ensure uniform air circulation in the thawing chamber to promote the thawing process.

[0082] Drain pipe: The bottom of the thawing chamber is equipped with a drain pipe, which can quickly drain the water generated during thawing and the water during the humidification process from the thawing chamber. This helps to maintain the dryness and cleanliness in the thawing chamber, avoiding water accumulation and moisture retention.

[0083] First, when the user puts the item to be thawed into the thawing chamber, the weight sensor will sense the initial weight of the item to be thawed. Based on the weight information, the system will automatically select the thawing mode. When it is detected that 0 < the initial weight M0 of the item to be thawed < M1 (M1 is the weight value set by the system), it will enter the low-power mode for thawing; when it is detected that M1 < the initial weight M0 of the item to be thawed < M2 (M2 is the weight value set by the system), it will enter the normal-power mode for thawing; when it is detected that the initial weight M0 of the item to be thawed > M2, it will enter the high-power mode for thawing. Once the thawing mode is entered, the temperature and humidity sensors in the thawing chamber will immediately collect the initial temperature and humidity data in the thawing chamber, and prompt the user to set the preset thawing temperature, humidity, and time parameters according to the type and quantity of different items to be thawed. With the completion of the preset parameters, when entering the low-power mode, the system will automatically start the auxiliary heating wire, the semiconductor refrigeration chip group, and the fan at the top to start thawing the item to be thawed. During the thawing process, the temperature and humidity sensors will continuously and real-time collect the temperature and humidity data in the thawing chamber. If the collected temperature data is lower than the preset temperature value, the system will automatically increase the rotation speed of the fan to accelerate the temperature in the thawing chamber to reach the preset value. Similarly, when entering the normal-power mode, the main heating wire and the semiconductor refrigeration chip group will be turned on, and the fan will be used to accelerate the temperature in the thawing chamber to reach the preset value; in the high-power mode, the main and auxiliary heating wires and the semiconductor refrigeration chip group will be turned on, and the fan will be used to accelerate the temperature in the thawing chamber to reach the preset value. At the same time, the system will monitor the humidity in the thawing chamber to ensure that the humidity will not be too low, so as not to affect the quality of the item to be thawed. If the humidity does not reach the preset humidity value, the system will turn on the humidifier located inside the thawing chamber and continuously increase the humidity until it meets the preset humidity requirements. After both the temperature and humidity reach the preset values, the system will maintain the current power operation to maintain these conditions. At this time, the wastewater generated during the thawing process and the water sprayed by the humidifier will be quickly discharged through the drain pipe at the bottom of the thawing chamber to keep the thawing chamber dry and clean. When the entire system runs to the preset thawing time, the system will automatically exit the thawing mode and send a prompt to the user that the thawing is completed. After the item to be thawed is taken out, the water output of the humidifier can be increased to clean the blood in the thawing chamber. This automated thawing process ensures high-quality thawing of the item to be thawed, reduces user operation intervention, and improves the thawing efficiency.

[0084] The beneficial effects of the thawing device in this embodiment are as follows:

[0085] 1. Energy saving: The device includes three different modes, namely the low-power mode, the normal-power mode, and the high-power mode. These three thawing modes correspond to items to be thawed of different sizes, avoiding waste of energy.

[0086] 2. Uniform thawing: On the one hand, the hot end of the thermoelectric cooler is used to heat the bottom of the object to be thawed, ensuring that the temperature at the bottom of the object to be thawed is effectively increased; on the other hand, the device is designed with an efficient air duct system to ensure uniform air circulation. This helps to distribute heat more evenly, increase the thawing speed, and at the same time reduce the moisture loss on the surface of the object to be thawed. This also helps to maintain the quality of the object to be thawed.

[0087] 3. Prevention of over-thawing: A moisture replenishment system is introduced into the thawing chamber to adjust the humidity of the thawing chamber in real time, prevent the object to be thawed from over-thawing and dehydrating, ensure that the object to be thawed maintains an appropriate moisture content, and thus improve the taste of the object to be thawed.

[0088] In summary, the thawing device of this embodiment gives full play to the functions of each component to achieve the high efficiency and accuracy of thawing the object to be thawed.
