[0026] The technical solution of the present invention adopts a cold storage chamber and a high-pressure thawing device, wherein the high-pressure thawing device is arranged in the cold storage chamber, and the high-pressure thawing device includes a first electrode plate and a second electrode plate, and the first electrode plate and the second electrode plate define a thawing space for placing the material to be thawed, and the first electrode plate and the second electrode plate are used to generate a high-voltage electric field when powered on, so as to thaw the material to be thawed placed in the thawing space with high pressure; at least one of the first electrode plate and the second electrode plate is connected to the cold storage chamber for heat exchange, and the high-pressure thawing device is also used to exchange heat between the material to be thawed placed in the thawing space and the cold storage chamber, so as to thaw the material to be thawed placed in the thawing space by heat exchange.

When the thawed material is placed in the thawing space, the high-voltage electric field can destroy the hydrogen bonds that play a key role in the ice layer of the material to be thawed, so that the ice layer structure dissociates into small molecular cluster structures. At the same time, the high-voltage electric field can ionize high-speed moving charged particles to collide with the surface of the material to be thawed, thereby accelerating the movement of its surface water molecules. Therefore, compared with the natural thawing method and the water thawing method, the thawing speed, especially the low-temperature thawing speed, is greatly improved. Furthermore, since the movement of water molecules is promoted, it is beneficial to promote the separation of surface water of the material to be thawed. At the same time, the high-voltage electric field can also promote the ionization of water molecules to form plasma. On the one hand, it can reduce the reduction in thermal conductivity caused by the presence of surface liquid water, thereby improving the heat exchange thawing efficiency of the electrode plate, thereby greatly improving the thawing speed compared to the thermal conduction thawing method. On the other hand, the generated plasma can also have a sterilizing and preserving effect, which can further reduce the quality deterioration of food during the thawing process. Therefore, while improving the thawing speed, it also solves the problem of meat quality degradation caused by the water thawing method. In addition, since the refrigeration equipment of the present invention adopts a combined thawing method of high-voltage electric field and heat exchange in the refrigeration chamber, the thawing environment temperature requirement is relatively low, and it only needs to be higher than the temperature of the material to be thawed. Therefore, it can be placed in the refrigeration chamber of the refrigeration equipment for low-temperature thawing, without the need for a separate thawing chamber. While improving the thawing speed, it avoids the problem of meat quality damage caused by heating and the problem of meat easy ripening caused by uneven heating. At the same time, it is also beneficial to improve the space utilization rate of the refrigeration equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention provides a refrigeration device.

[0037] The present invention provides a refrigeration device, which may be a refrigerator or a freezer.

[0038] At present, the thawing methods commonly used by users can be divided into natural thawing, water thawing and thermal thawing. Natural thawing is to place the material to be thawed in the environment and thaw it through natural convection heat exchange. The thawing time is generally more than 3 to 4 hours, which is difficult to meet the increasingly fast pace of modern life. In addition, the meat ingredients lose a lot of water after thawing, and are very easy to deform, which is not convenient for subsequent cooking. The water thawing method is to place the material to be thawed in water or pour water on the material to be thawed to thaw. Although the thawing speed is slightly faster than the natural thawing method, the actual thawing time is still longer. In addition, the material to be thawed is prone to breeding bacteria when placed in water, and the water content of the meat ingredients will increase after thawing, resulting in a significant decline in meat quality. The thermal conduction thawing method is to bring the material to be thawed into contact with a heat source so that the heat source conducts heat to the material to be thawed for thawing. However, during the thermal conduction thawing process, the ice crystals on the surface of the frozen food first melt into water. Since the thermal conductivity coefficient of water is lower than that of ice, the thawing speed of the material to be thawed becomes slower and slower. Although the overall thawing speed is improved compared with the above two thawing methods, the thawing time is still longer.

[0039] Regarding the above issues, refer to Figures 1 to 3 In one embodiment, the refrigeration equipment includes:

[0040] a refrigerating chamber 100; and

[0041] A high-pressure thawing device 200 is provided in the cold storage chamber 100. The high-pressure thawing device 200 includes a first electrode plate 210 and a second electrode plate 220. The first electrode plate 210 and the second electrode plate 220 define a thawing space for placing the material to be thawed. The first electrode plate 210 and the second electrode plate 220 are used to generate a high-voltage electric field when energized to thaw the material to be thawed placed in the thawing space at high pressure.

[0042] At least one of the first electrode plate 210 and the second electrode plate 220 is connected to the cold storage chamber 100 for heat exchange, and the high-pressure thawing device 200 is also used to exchange heat between the material to be thawed placed in the thawing space and the cold storage chamber 100 to thaw the material to be thawed placed in the thawing space by heat exchange.

[0043] In this embodiment, the first electrode plate 210 and the second electrode plate 220 can be arranged relative to each other at a distance from each other so that either of them can have an area directly opposite to the other, and a thawing space is defined between the first electrode plate 210 and the second electrode plate 220. Corresponding electrodes can be provided in the first electrode plate 210 and the second electrode plate 220. The high-voltage thawing assembly can be connected to a dedicated high-voltage generator or a power supply module in a refrigeration device to receive at least one high-current value preset power supply current output by the dedicated high-voltage generator or the refrigeration device power supply module, and can output the current to the electrode of at least one of the first electrode plate 210 and the second electrode plate 220, so that the energized first electrode plate 210 and the second electrode plate 220 can form an equipotential surface having an electric potential corresponding to the power supply current, thereby forming a high-voltage electric field between the first electrode plate 210 and the second electrode plate 220 that passes through the thawing space.

[0044] Here, the formation of the high-voltage electric field of the present invention is explained by taking the preset power supply current as a direct current as an example. A direct current high-voltage electric field can be formed by passing a positive polarity direct current into one of the first electrode plate 210 and the second electrode plate 220, and not passing power to the other. In this case, the direction of the direct current high-voltage electric field can be from the energized electrode plate to the unenergized electrode plate. Alternatively, a direct current high-voltage electric field can be formed by passing a negative polarity direct current into one of the first electrode plate 210 and the second electrode plate 220, and not passing power to the other. In this case, the direction of the direct current high-voltage electric field can be from the unenergized electrode plate to the energized electrode plate. Alternatively, a direct current high-voltage electric field can be formed by passing a positive polarity direct current into one of the first electrode plate 210 and the second electrode plate 220, and not passing power to the other. In this case, the direction of the direct current high-voltage electric field can be from the unenergized electrode plate to the energized electrode plate. Alternatively, a direct current high-voltage electric field can be formed by passing a positive polarity direct current into one of the first electrode plate 210 and the second electrode plate 220, and passing a negative polarity direct current into the other. In this case, the direction of the direct current high-voltage electric field can be from the positive potential electrode plate to the negative potential electrode plate. Alternatively, a DC high-voltage electric field can be formed by passing a positive / negative polarity DC current of a larger current value into one of the first electrode plate 210 and the second electrode plate 220, and passing a positive / negative polarity DC current of a smaller current value into the other. At this time, the direction of the DC high-voltage electric field can be from the electrode plate with a larger positive potential to the electrode plate with a smaller positive potential, or from the electrode plate with a smaller negative potential to the electrode plate with a larger negative potential. Of course, the supply current can also be an AC current, so that an AC high-voltage electric field can be formed between the first electrode plate 210 and the second electrode plate 220. The method of passing the AC current can refer to the above-mentioned DC current and will not be described in detail here. In short, the high-voltage electric field generated by the high-pressure thawing component of the present invention can be divided into two types: a DC high-voltage electric field and an AC high-voltage electric field according to the type of supply current passed.

[0045] When the first electrode plate 210 and the second electrode plate 220 form a high-voltage electric field, at least one of the first electrode plate 210 and the second electrode plate 220 can be configured to be in contact with or at a predetermined distance from the material to be thawed, and a heat exchange channel can be provided in the one in contact with or at a predetermined distance from the material to be thawed. The heat exchange channel can be connected to the heat exchange fluid output from the dedicated liquid reservoir in the cold storage chamber 100; or, it can be connected to the heat exchange fluid output from the refrigeration system 300 of the refrigeration equipment to the cold storage chamber 100 after being cooled by the cold storage chamber 100. Since the temperature of the material to be thawed is usually below zero, and the temperature of the cold storage chamber 100 is usually not less than 0°C and not more than 15°C, the temperature of the heat exchange fluid connected to the heat exchange channel can be the temperature of the cold storage chamber 100, which is relatively high for the material to be thawed. In this way, when the temperature of the electrode plate where the heat exchange channel is located decreases due to heat exchange contact with or proximity to the material to be thawed, the heat exchange channel can exchange the lower heat of the electrode plate with the higher heat of the heat exchange fluid to increase the temperature of the electrode plate and enable the electrode plate to output the heat exchange fluid with a lower temperature after heat exchange, thereby achieving heat exchange between the material to be thawed and the cold storage chamber 100. This cycle is repeated, so that the first electrode plate 210 or the second electrode plate 220 can continuously and efficiently thaw the material to be thawed through heat exchange. It should be noted that when only one of the first electrode plate 210 and the second electrode plate 220 is provided with a heat exchange channel, the electrode plate provided with the heat exchange channel can be the electrode plate that is in contact with or close to the material to be thawed when the high-voltage electric field is formed. In addition, the first electrode plate 210 and the second electrode plate 220 can be connected to the same heat exchange fluid with the same heat exchange efficiency, or two heat exchange fluids with different heat exchange efficiencies, without limitation here. For example: in actual use, one of the first electrode plate 210 and the second electrode plate 220 can be reused as a substrate for placing the material to be thawed, and the contact area between the electrode plate reused as the substrate and the material to be thawed is often larger. At this time, the electrode plate reused as the substrate can be configured to access a heat exchange fluid with higher heat exchange efficiency, such as a heat exchange fluid with a higher temperature or a higher heat transfer coefficient, to meet the heat exchange requirements of a larger contact area. The other electrode plate can be configured to access a heat exchange fluid with lower heat exchange efficiency, such as a heat exchange fluid with a lower temperature or a lower heat transfer coefficient.

[0046] In another embodiment, at least one of the first electrode plate 210 and the second electrode plate 220 (typically the electrode plate that serves as the substrate) may also be provided with a thermal storage material. The thermal storage material may be an organic phase change thermal storage material or an inorganic phase change thermal storage material. The electrode plate containing the thermal storage material can absorb heat from the cold storage chamber 100 to adjust its own temperature to the cold storage chamber 100 temperature, thereby storing heat in the cold storage chamber 100 environment. When material to be thawed is placed on the electrode plate, the thermal storage material can utilize its own cold storage chamber 100 temperature to thaw the material. It is understood that when the temperature of the electrode plate on which the thermal storage material is located drops due to heat exchange thawing, the thermal storage material absorbs heat from the cold storage chamber 100 to maintain the temperature of the electrode plate on which the thermal storage material is located at a stable temperature of the cold storage chamber 100. Furthermore, because the refrigeration equipment itself can maintain a stable temperature in the cold storage chamber 100, the first and second electrode plates 210 and 220 can continuously and efficiently thaw the material to be thawed through heat exchange.

[0047] Thus, when the material to be thawed is placed in the thawing space, the high-voltage electric field disrupts the key hydrogen bonds in the ice layer of the material to be thawed, causing the ice layer structure to dissociate into small molecular clusters. Simultaneously, the high-voltage electric field ionizes high-speed charged particles that impact the surface of the material to be thawed, accelerating the movement of surface water molecules. This significantly increases the thawing speed, especially at low temperatures, compared to natural thawing and water thawing methods. Furthermore, by promoting the movement of water molecules, it facilitates the separation of surface water from the material to be thawed. The high-voltage electric field also promotes the ionization of water molecules to form plasma, which, on the one hand, reduces the reduction in thermal conductivity caused by the presence of surface liquid water, thereby improving the heat exchange thawing efficiency of the electrode plates. Consequently, the thawing speed is significantly improved compared to thermal conduction thawing methods. Furthermore, the generated plasma can also have a sterilizing and preserving effect, further reducing the quality deterioration of food during the thawing process. Therefore, while increasing the thawing speed, it also solves the problem of meat quality degradation that is common with water thawing methods.

[0048] There are two thawing methods in the prior art, namely the thermal convection thawing method and the electromagnetic thawing method. The thermal convection thawing method uses hot air or hot water to directly heat and thaw. Although it can quickly heat and thaw, it will cause serious problems in the quality of meat, affecting the subsequent cooking process and the taste of the food. In addition, thermal convection will affect the normal refrigeration environment of the refrigeration equipment. Therefore, using this method requires the establishment of a separate thawing chamber, resulting in a waste of space in the refrigeration equipment. The electromagnetic thawing method converts the energy carried by electromagnetic waves into thermal energy of the material to be thawed to increase the thawing speed, but the electromagnetic thawing method has the disadvantages of uneven heating of the material to be thawed and the meat is very easy to mature after thawing.

[0049] In response to the above problems, the refrigeration equipment of the present invention adopts a combined thawing method of high voltage electric field and heat exchange in the refrigeration chamber 100, so the thawing environment temperature requirement is relatively low, which only needs to be higher than the temperature of the material to be thawed. Therefore, it can be placed in the refrigeration chamber 100 of the refrigeration equipment for low-temperature thawing, and there is no need to set up a separate thawing chamber. This avoids the problem of meat quality damage caused by heating and the problem of meat easy ripening caused by uneven heating while improving the thawing speed. At the same time, it is also beneficial to improve the space utilization of the refrigeration equipment.

[0050] Reference Figure 2 In one embodiment, the high-pressure thawing device 200 further includes:

[0051] Insulating base 230;

[0052] A guide rail assembly 240, wherein the guide rail assembly 240 and the second electrode plate 220 are disposed on the insulating base 230; the first electrode plate 210 is movably connected to the guide rail assembly 240 and disposed opposite to the second electrode plate 220;

[0053] The support assembly 250 is connected to the first electrode plate 210 and the second electrode plate 220 . The support assembly 250 is used to drive the first electrode plate 210 to move closer to or away from the second electrode plate 220 along the guide rail assembly 240 .

[0054] In this embodiment, the insulating base 230 can be made of an insulating material such as plastic to provide support for the installation of the various components of the thawing device of the present invention. The insulating base 230 can have a first side surface and a second side surface that are opposite in the width direction. Because the thawing device of the present invention can be directly installed in the refrigerator compartment 100, the insulating base 230 can effectively prevent accumulated water in the refrigerator compartment 100 from directly contacting the second electrode plate 220, thereby eliminating the risk of short circuit and electric shock when the user handles thawed materials, thereby improving the safety of the thawing device of the present invention.

[0055] The guide rail assembly 240 may include at least one guide rail, each of which may extend in the direction of gravity. The first end of each guide rail may be fixedly disposed near the first side surface of the insulating base 230, and the other end may extend away from the insulating base 230. The second electrode plate 220 may be a nearly rectangular body and may be disposed on the upper surface of the insulating base 230 corresponding to the guide rail assembly 240, so that the first electrode plate 210 may be partially or completely located directly above the second electrode plate 220. In other words, in this embodiment, the second electrode plate 220 is used to place the material to be thawed. The first electrode plate 210 may also be a nearly rectangular body, and the first electrode plate 210 may be provided with corresponding through holes corresponding to each guide rail in the guide rail assembly 240, so that the two can be movably connected by being sleeved on the guide rail assembly 240.

[0056] The support assembly 250 may include a first support member 251 and a second support member 252. The first electrode plate 210 and the second electrode plate 220 may have a first side surface along their length, the first side surface having a first end proximal to the guide rail assembly 240 and a second end distal to the guide rail assembly 240. A slide rail 255 may be provided on the second end. Thus, the first end of the first support member 251 may be rotatably connected to the first end of the first side surface of the first electrode plate 210, and the other end may be slidably connected to the slide rail 255 on the first side surface of the second electrode plate 220. The second support member 252 may have one end rotatably connected to the first end of the first side surface of the second electrode plate 220, and the other end may be slidably connected to the slide rail 255 on the first side surface of the first electrode plate 210. One of the first support member 251 and the second support member 252 may further include a corresponding projection portion. The projection portions of the two support members may be rotatably connected via a tubular connector to enhance the consistency of the coordinated movement of the first support member 251 and the second support member 252, thereby enabling the first set of support members to form an "X"-shaped structure.

[0057] The first electrode plate 210 and the second electrode plate 220 may further have a second side opposite to the first side in the length direction. In this case, the support assembly 250 may further include a third support member 253 and a fourth support member 254. The second side may also have a first end close to the guide rail assembly 240 and a second end away from the guide rail assembly 240, wherein the second end may be provided with a slide rail 255; thus, the first end of the third support member 253 may be rotatably connected to the first end of the second side of the first electrode plate 210, and the other end may be slidably connected to the slide rail 255 on the second side of the second electrode plate 220; one end of the fourth support member 254 may be rotatably connected to the first end of the second side of the second electrode plate 220, and the other end may be slidably connected to the slide rail 255 on the second side of the first electrode plate 210. One of the third support member 253 and the fourth support member 254 also has a projection portion corresponding to the other, and the projection portions of the two can be rotatably connected through a tubular connecting member or a columnar connecting member to increase the consistency of the coordinated movement of the third support member 253 and the fourth support member 254, and enable the second group of support members as a whole to present an "X"-shaped structure.

[0058] In this way, when the second ends of the first support member 251 to the fourth support member 254 move on the slide rail 255 in a direction away from the guide rail assembly 240, the first electrode plate 210 can move toward the second electrode plate 220; when the second ends of the first support member 251 to the fourth support member 254 move on the slide rail 255 in a direction close to the guide rail assembly 240, the first electrode plate 210 can move away from the second electrode plate 220, so that the user can adjust the distance between the first electrode plate 210 and the second electrode plate 220, so that the distance between the two electrode plates can be flexibly adapted to different sizes of materials to be thawed.

[0059] exist Figure 2In the illustrated embodiment, the guide rail assembly 240 includes a first guide rail 241 and a second guide rail 242. The first guide rail 241 and the second guide rail 242 are symmetrically arranged about the midline of the second electrode plate 220 in the width direction. This ensures that the high-voltage electric field formed by the first electrode plate 210 and the second electrode plate 220 can effectively pass through the material to be thawed placed on the second electrode plate 220. When the second electrode plate 220 is placed on the insulating base 230, one side of the second electrode plate 220 can be flush with the second side of the insulating base 230. The insulating base 230 may also be provided with a corresponding fixing assembly 280 corresponding to the geometric shape of the second electrode plate 220. The fixing assembly 280 includes a fixing plate 281 and two fixing columns 282. The fixing plate 281 may be arranged close to the first side surface of the insulating base 230 and may be arranged between the first guide rail 241 and the second guide rail 242. The two fixing columns 282 may be respectively connected to the second side surface of the insulating base 230 to ensure that the second electrode plate 220 is fixed to the upper surface of the insulating base 230 to avoid the placement of the material to be thawed or the downward pressure of the first electrode plate 210, which may cause the position of the second electrode plate 220 to shake, thereby affecting the high-pressure thawing effect; the fixing plate 281 and the two fixing columns 282 may also be symmetrically arranged about the center line of the second electrode plate 220 in the width direction to increase the fixation of the fixing assembly 280 to the second electrode plate 220.

[0060] exist Figure 2 In the illustrated embodiment, the thawing device may further include an insulating bracket 290. The insulating bracket 290 may have a nearly "C"-shaped structure and may be fixedly disposed near the first side surface of the insulating base 230 to enclose a guide rail installation space with the upper surface of the insulating base 230, so that the end of each guide rail facing away from the insulating base 230 may be fixedly connected to the insulating bracket 290, thereby increasing the stability of the first electrode plate 210 moving along the guide rail assembly 240. The connection between the insulating bracket 290 and the junction base may also face the direction of the second side surface of the insulating base, and may be sequentially connected to a first extension portion and a second extension portion, wherein the first extension portion may be nearly trapezoidal and the second extension portion may be nearly rectangular, so as to increase the contact area between the insulating bracket 290 and the insulating base 230 to increase installation stability.

[0061] Optionally, the first electrode plate 210 has a first surface facing the second electrode plate 220 , and the first surface of the second electrode plate 220 is provided with a pointed discharge structure facing the second electrode plate 220 .

[0062] In this embodiment, the first surface of the first electrode plate 210 may be its lower surface, and a corresponding pointed discharge structure may be provided on the lower surface. One end of the pointed discharge structure may be connected to the lower surface of the first electrode plate 210, and the other end may be disposed toward the second electrode plate 220 to ensure that a high-voltage electric field is formed with the second electrode plate 220. The pointed discharge structure may be any one or more combinations of discharge structures such as a needle-shaped structure, a thin-line structure, and a mesh structure, and is not limited here.

[0063] Optionally, a heat exchange channel is provided in the second electrode plate;

[0064] The high-pressure thawing device 200 further includes a liquid storage tank 260 for storing heat exchange fluid, wherein the liquid outlet of the liquid storage tank 260 is in communication with the liquid inlet of the heat exchange channel, and the liquid inlet of the liquid storage tank 260 is in communication with the liquid outlet of the heat exchange channel to form a heat exchange fluid circuit;

[0065] The liquid storage tank 260 is used to output the stored heat exchange fluid to the heat exchange channel and receive the heat exchange fluid returned from the heat exchange channel after heat exchange.

[0066] In this embodiment, the heat exchange fluid can be water, ethanol, cooking oil and other non-toxic and harmless liquids with high heat exchange efficiency to avoid food safety problems caused by leakage. The liquid storage tank 260 can be arranged on the insulating base 230 to use the ambient temperature of the thawing device to exchange heat with the stored heat exchange fluid, so that the output heat exchange fluid can have a higher temperature of the cold storage chamber 100 than the temperature of the substance to be thawed, and can also make the lower temperature of the connected heat exchange fluid rise to the temperature of the cold storage chamber 100. In this way, when the thawing device is arranged in the cold storage chamber 100, it is possible to use the temperature of the cold storage chamber 100 to perform low-temperature heat exchange thawing of the substance to be thawed. The volume of the liquid storage tank 260 can be selected from a range of not less than 100ml and not more than 800mL to meet the heat exchange and thawing requirements of different cold storage chambers 100. Figures 1 to 3 In the example shown, the liquid storage tank 260 and the high voltage generator are located on the same side of the insulating bracket 290, and the liquid outlet and liquid inlet of the liquid storage tank 260 are arranged on the back to improve the aesthetics of the thawing device, and the liquid outlet is located below the liquid inlet.

[0067] Reference Figure 3 In one embodiment, a circulation pump C4 and / or a first control valve C1 are provided on the heat exchange fluid circuit.

[0068] The first control valve C1 can be a solenoid proportional valve; it is used to control the flow rate of the heat exchange fluid in the heat exchange channel based on its valve body opening, thereby controlling the heat exchange and thawing efficiency of the high-pressure thawing device 200. The circulation pump C4 can be a unidirectional circulation pump C4, and the flow direction supported by the circulation pump C4 can be set to be consistent with the flow direction of the heat exchange fluid in the heat exchange channel; the circulation pump C4 is used to provide power for the flow of the heat exchange fluid in the heat exchange channel.

[0069] Reference Figure 3 In one embodiment, the refrigeration equipment further comprises:

[0070] Refrigeration system 300, having a refrigerant circuit;

[0071] The heat exchange device 400 has a first circulation channel 410 and a second circulation channel 420. The first circulation channel 410 is connected to the second circulation channel 420 for heat exchange. The first circulation channel 410 is connected in series to the heat exchange fluid circuit, and the second circulation channel 420 is connected to the refrigerant circuit.

[0072] When in operation, the refrigeration system 300 can continuously perform an evaporation-condensation cycle on the refrigerant circulating in the refrigerant circuit, and can utilize the evaporation process to cool the refrigeration compartment 100, thereby maintaining a low temperature in the refrigeration compartment 100. The heat exchange device 400 may include a housing and a first circulation channel 410 and a second circulation channel 420 disposed through the housing. The first circulation channel 410 and the second circulation channel 420 may be implemented as a tubular structure, and the housing of the heat exchange device 400 may also be filled with a heat exchange material to achieve a heat exchange connection between the first circulation channel 410 and the second circulation channel 420.

[0073] In this embodiment, the first circulation channel 410 can be connected in series with the heat exchange fluid circuit in the form of a main circuit, that is, the first circulation channel 410 can be a partial circuit of the heat exchange fluid circuit, so as to fully receive the heat exchange fluid flowing through the heat exchange fluid circuit; or, it can be connected in series with the heat exchange fluid circuit in the form of a branch circuit, that is, the two ends of the first circulation channel 410 can be connected to the heat exchange fluid circuit respectively, so as to divert the heat exchange fluid flowing through the heat exchange fluid circuit and return the heat exchanged heat exchanged fluid to the heat exchange fluid circuit. Similarly, the second circulation channel 420 can be connected in series with the refrigerant circuit in the form of a main circuit, that is, the second circulation channel 420 can be a partial circuit of the refrigerant circuit, so as to fully receive the refrigerant flowing through the refrigerant circuit; or, it can be connected in series with the refrigerant circuit in the form of a branch circuit, that is, the two ends of the second circulation channel 420 can be connected to the refrigerant circuit respectively, so as to divert the refrigerant flowing through the refrigerant circuit and return the refrigerant to the refrigerant circuit after heat exchange.

[0074] In actual use, the refrigerant in the refrigerant circuit may be higher than the temperature of the cold storage chamber 100. Therefore, the heat exchange device 400 can use the refrigerant liquid connected to the second circulation channel 420 to increase the temperature of the heat exchange fluid connected to the first circulation channel 410, so as to increase the temperature of the heat exchange fluid in the entire heat exchange fluid circuit, so that the high-pressure thawing device 200 can use the heat exchange fluid with a higher temperature to thaw the material to be thawed, which is beneficial to improve the heat exchange and thawing efficiency of the material to be thawed.

[0075] It should be noted that the first circulation channel 410 can be connected in series to a portion of the heat exchange fluid circuit between the liquid outlet of the liquid storage tank 260 and the liquid inlet of the heat exchange channel. This allows the heat exchange fluid, which has a higher temperature after heat exchange with the refrigerant, to flow into the high-pressure thawing device 200 in a shorter time, and also allows the heat exchange fluid returning to the liquid storage tank 260 to be at a lower temperature. Compared to connecting the first circulation channel 410 in series to a portion of the heat exchange fluid circuit between the liquid outlet of the heat exchange channel and the liquid inlet of the liquid storage tank 260, the temperature of the liquid storage tank 260 and the heat exchange fluid stored therein during the thawing process can be close to the temperature of the refrigeration chamber 100, thereby having a smaller impact on the temperature of the refrigeration environment of the refrigeration chamber 100. This improves the heat exchange thawing efficiency of the thawed material while ensuring the refrigeration effect of the refrigeration chamber 100, thereby improving the practicality of the refrigeration device of the present invention.

[0076] Optionally, the refrigeration system 300 includes a compressor 271, a condenser 272, a capillary tube 273 and an evaporator 274, wherein the compressor 271, the condenser 272, the capillary tube 273 and the evaporator 274 are sequentially connected end to end in series to form a refrigerant circuit;

[0077] The refrigerant circuit comprises a first refrigerant branch (L1) located between the compressor (271) and the condenser (272), a second refrigerant branch (L2) located between the condenser (272) and the capillary tube (273), a third refrigerant branch (L3) located between the capillary tube (273) and the evaporator (274), and a fourth refrigerant branch (L4) located between the evaporator (274) and the compressor (271);

[0078] Any two of the first refrigerant branch L1 , the second refrigerant branch L2 , the third refrigerant branch L3 , and the fourth refrigerant branch L4 are in one-to-one communication with both ends of the second circulation channel 420 .

[0079] In this embodiment, the liquid outlet of the compressor 271 can be connected to the liquid inlet of the condenser 272 via the first refrigerant branch L1, the liquid outlet of the condenser 272 can be connected to the liquid inlet of the capillary tube 273 via the second refrigerant branch L2, the liquid outlet of the capillary tube 273 can be connected to the liquid inlet of the evaporator 274, and the liquid outlet of the evaporator 274 can be connected to the liquid inlet of the compressor 271, thereby forming a refrigerant circuit. The compressor 271 is used to compress the low-temperature, low-pressure refrigerant gas from the evaporator 274 into a high-temperature, high-pressure refrigerant gas and output it to the condenser 272; the condenser 272 is used to condense and cool the high-temperature, high-pressure refrigerant gas into a refrigerant liquid and output it to the capillary tube 273; the capillary tube 273 is used to decompress the refrigerant liquid and output it to the evaporator 274; the evaporator 274 is used to heat the refrigerant liquid and evaporate it into refrigerant gas, and uses the heat absorbed during the evaporation process to maintain the low temperature of the refrigeration chamber 100.

[0080] The second circulation channel 420 is connected in series to the refrigerant circuit in the form of a branch circuit. The two ends of the second circulation channel 420 can be connected to any two of the first refrigerant branch L1, the second refrigerant branch L2, the third refrigerant branch L3, and the fourth refrigerant branch L4 respectively. One end can be diverted and connected to the refrigerant liquid or refrigerant gas with a higher temperature flowing through the refrigerant circuit to exchange heat and increase the temperature of the heat exchange fluid, and the other end can return the refrigerant liquid or refrigerant gas after heat exchange to the refrigerant circuit.

[0081] Optionally, the first refrigerant branch L1 and the second refrigerant branch L2 are connected one-to-one with both ends of the second circulation channel 420. This configuration allows the second circulation channel 420 to receive the high-temperature, high-pressure refrigerant gas output by the compressor 271 to exchange heat and increase the temperature of the heat exchange fluid. Since the temperature of the refrigerant gas output by the compressor 271 is the highest in the refrigerant circuit, the second circulation channel 420 can effectively improve the heating effect of the heat exchange fluid. In addition, the second circulation channel can also output the refrigerant liquid after heat exchange and cooling to the second refrigerant branch L2. Since the refrigerant liquid flowing through the second refrigerant branch L2 should already be the refrigerant liquid condensed and cooled by the condenser 272, even if the refrigerant liquid output after heat exchange and cooling is connected to the second circulation channel 420, it will not affect the operation of the capillary tube 273 and the evaporator 274. Therefore, while improving the heating effect of the heat exchange fluid, the normal operation of the refrigeration circuit is guaranteed, which is conducive to improving the practicality of the refrigeration device of the present invention.

[0082] Optionally, at least one of the two ends of the second circulation channel 420 is connected to the refrigerant circuit via a second control valve C2 (hereinafter referred to as the second control valve C2).

[0083] The second control valve C2 can be a solenoid proportional valve; the second control valve C2 is used to control the refrigerant flow rate in the second heat exchange channel based on its valve opening. Since the refrigerant flow rate in the second heat exchange channel is proportional to the temperature increase of the heat exchange fluid in the first circulation channel 410, the thawing efficiency of the refrigeration system 300 can be controlled by controlling the valve opening of the second control valve C2. It is understood that the valve opening of the second control valve C2 can be selected from a range of not less than 0% and not greater than 100%. For example, by controlling the valve opening of the second control valve C2 to 0%, the heat exchange fluid circuit thaws the thawed material with heat exchange fluid at the temperature of the refrigeration chamber 100, thereby achieving gentle thawing. Alternatively, by controlling the valve opening of the second control valve C2 to 100%, the heat exchange fluid circuit thaws the thawed material with heat exchange fluid at a temperature greater than that of the refrigeration chamber 100, thereby achieving rapid thawing.

[0084] Optionally, the refrigerant circuit includes a first communication port B1 and a second communication port that are in one-to-one communication with both ends of the second circulation channel 420; and a fifth refrigerant branch located between the first communication port B1 and the second communication port B2;

[0085] A third control valve C3 is provided on the fifth refrigerant branch line.

[0086] The fifth refrigerant branch can be determined in real time based on the connection positions of the liquid inlet and liquid outlet of the second circulation channel 420 on the refrigerant circuit. For example, when the liquid inlet and liquid outlet of the second circulation channel 420 are in one-to-one communication with the first refrigerant branch L1 and the second refrigerant branch L2, the fifth refrigerant branch may include the portion of the first refrigerant branch L1 between the liquid inlet of the second circulation channel 420 and the liquid inlet of the condenser 272, the condenser 272, and the portion of the second refrigerant branch L2 between the liquid outlet of the condenser 272 and the liquid outlet of the second circulation channel 420.

[0087] The third control valve C3 may be a solenoid proportional valve; the third control valve C3 is used to control the refrigerant flow rate in the fifth refrigerant branch according to its valve body opening. In conjunction with the second control valve C2, the third control valve C3 can adjust the refrigerant flow ratio between the fifth refrigerant branch and the second circulation channel 420. It is understood that the valve body opening of the third control valve C3 can be selected from a range of not less than 0% and not greater than 100%. For example, by controlling the valve body opening of the second control valve C2 to 0% and the valve body opening of the third control valve C3 to 100%, gentle thawing of the thawed material using the heat exchange fluid at the temperature of the refrigeration chamber 100 can be achieved. Alternatively, by controlling the valve body opening of the second control valve C2 to 100% and the valve body opening of the third control valve C3 to 0%, all the refrigerant in the refrigerant circuit can flow into the second heat exchange channel, rather than into the fifth refrigerant branch, thereby providing maximum heat exchange and heating efficiency for the heat exchange fluid.

[0088] One of the first communication port B1 and the second communication port B2 is a liquid inlet, and the other is a liquid outlet. The third control valve C3 is arranged on the fifth refrigerant branch line near the liquid inlet. Figure 3 In the illustrated embodiment, the first communication port B1 is a liquid inlet, and the third control valve C3 is disposed between the first communication port B1 and the liquid inlet of the condenser 272 .

[0089] Reference Figure 3 In one embodiment, the refrigeration device further includes a plurality of partitions 500 disposed in the refrigeration chamber 100, wherein the plurality of partitions 500 are spaced apart to form a plurality of sub-refrigeration chambers 110 arranged in sequence in a preset direction;

[0090] The high-pressure thawing device 200 is disposed in the last sub-refrigerating chamber 110 in a preset direction.

[0091] In this embodiment, the preset direction may be the direction of gravity or the horizontal direction. A plurality of limiting slides may be provided in the refrigerating chamber 100, wherein at least two limiting slides may be provided on the two inner walls of the refrigerating chamber 100 in the direction of gravity or the horizontal direction relative to each other, and any two relative limiting slides may allow a partition 500 to be detachably provided in the refrigerating chamber 100. In this way, the user can remove the corresponding partition 500 according to actual needs to connect the two adjacent sub-refrigerating chambers 110 to facilitate the placement of large materials to be refrigerated; or, install the corresponding partition 500 to separate the two adjacent sub-refrigerating chambers 110 to facilitate the placement of small materials to be refrigerated. In this way, by arranging the high-pressure thawing device 200 in the last sub-refrigerating chamber 110 in the preset direction, especially when the preset direction is the direction of gravity, the height of the high-pressure thawing device 200 is more suitable, which is not only convenient for user operation, but also will not affect the normal placement and removal of the upper sub-freezer 700, which is conducive to improving the flexibility and convenience of use. Figure 3 In the illustrated embodiment, the refrigeration device is further provided with an insulation layer 600 corresponding to the refrigeration chamber 100 to effectively maintain a low temperature environment in the refrigeration chamber 100 when the food is not thawed or when the second circulation channel 420 is connected to the full refrigerant flow.

[0092] Optionally, the refrigeration device is provided with a freezing chamber 700. The freezing chamber 700 may be spaced apart from the refrigeration chamber 100 in the refrigeration device.
