[0035] Food needs to be stored in the refrigerator and kept in good quality by freezing in the refrigerator to prevent spoilage. A refrigeration component is provided inside the refrigerator to directly refrigerate the inside of the refrigerator. However, in the related art, the temperature difference between the refrigeration component and the inside of the refrigerator is too large, resulting in a large fluctuation in the temperature range inside the refrigerator during the refrigeration process and uneven cooling.

[0036] In order to solve the problems existing in the related art to a certain extent, the refrigerator provided by the embodiments of the present application can reduce the temperature range fluctuation in the accommodation cavity during the heat exchange process and improve the temperature uniformity in the accommodation cavity.

[0037] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0038] Please refer to Figures 1 - 8 , the embodiments of the present application provide a refrigerator 1, and the refrigerator 1 provided by the embodiments of the present application can reduce the temperature range fluctuation in the accommodation cavity 110 during the heat exchange process and improve the temperature uniformity in the accommodation cavity 110.

[0039] Please refer to Figure 1 , the refrigerator 1 provided by the embodiments of the present application includes a box body 100, a first refrigeration component 200, and a second refrigeration component 300. The box body 100 has an accommodation cavity 110 for accommodating items. The first refrigeration component 200 is used to refrigerate the heat exchange medium in the second refrigeration component 300, and at least part of the second refrigeration component 300 is installed inside the box body 100 for heat exchange with the accommodation cavity 110.

[0040] The cabinet 100 is the basic component of the refrigerator 1 of the present application. The cabinet 100 can provide an installation basis for at least some other components of the refrigerator 1, and can also serve the purpose of protecting at least some other components of the refrigerator 1. The accommodation cavity 110 is used to place various items that need to be stored frozen, such as meat, vegetables, etc. The first refrigeration component 200 has a refrigeration function. The second refrigeration component 300 contains a heat exchange medium. At least part of the second refrigeration component 300 can be installed in the sandwich layer of the cabinet 100, or can also be installed in the accommodation cavity 110, and there is no limitation on this.

[0041] Since the first refrigeration component 200 can refrigerate the heat exchange medium in the second refrigeration component 300, the refrigerated second refrigeration component 300 also has a refrigeration function. Since at least part of the second refrigeration component 300 is installed in the cabinet 100 and the accommodation cavity 110 is also opened in the cabinet 100, at least part of the second refrigeration component 300 installed in the cabinet 100 can exchange heat with the hot air in the accommodation cavity 110, so that the accommodation cavity 110 is kept at a low temperature to store items frozen. That is, in the embodiment of the present application, the first refrigeration component 200 does not directly refrigerate the accommodation cavity 110, but refrigerates the heat exchange medium in the second refrigeration component 300. After the heat exchange medium is refrigerated, it then refrigerates the accommodation cavity 110.

[0042] In the related art, a refrigeration system with a refrigeration function directly refrigerates the accommodation cavity 110, that is, there is only one heat exchange process. In the embodiment of the present application, since the first refrigeration component 200 refrigerates the heat exchange medium in the second refrigeration component 300, and the refrigerated heat exchange medium then refrigerates the accommodation cavity 110, that is, there are two heat exchange processes between the first refrigeration component 200 and the accommodation cavity 110. And a certain amount of heat is dissipated during each heat exchange. The heat dissipated through two heat exchange processes is greater than that through one heat exchange process. Thus, the temperature difference between the heat exchange medium and the accommodation cavity 110 can be reduced. Furthermore, during the heat exchange process, the temperature range fluctuation in the accommodation cavity 110 can be reduced, and the temperature uniformity in the accommodation cavity 110 can be improved, so that each item in the accommodation cavity 110 is evenly cooled.

[0043] In some embodiments, the heat exchange medium can be water. The specific heat capacity of water is relatively large, that is, the amount of heat absorbed or released when changing the unit temperature is relatively large. Therefore, after the first refrigeration component 200 refrigerates the water, with the same heat dissipation, the temperature of the water drops less, so that the temperature difference with the accommodation cavity 110 can be further reduced. Furthermore, during the heat exchange process, the temperature range fluctuation in the accommodation cavity 110 can be reduced, and the temperature uniformity in the accommodation cavity 110 can be improved.

[0044] In some embodiments, please refer to Figures 2 - 4, The second refrigeration assembly 300 includes a storage box 310, a connecting pipe 320 and a heat exchange pipe 330. The storage box 310 communicates with the heat exchange pipe 330 through the connecting pipe 320. The heat exchange pipe 330 is installed in the box body 100, and the first refrigeration assembly 200 is used to refrigerate the heat exchange medium in the storage box 310.

[0045] The heat exchange medium is stored in the storage box 310. The storage box 310 communicates with the heat exchange pipe 330 through the connecting pipe 320, and the heat exchange pipe 330 is installed in the box body 100. Between the storage box 310 and the connecting pipe 320, and between the connecting pipe 320 and the heat exchange pipe 330 are connected through connectors 311. A circulation loop is formed by connecting the storage box 310, the connecting pipe 320 and the heat exchange pipe 330. The heat exchange medium circulates between the storage box 310, the connecting pipe 320 and the heat exchange pipe 330. That is, after the heat exchange medium in the storage box 310 is refrigerated by the first refrigeration assembly 200, it enters the heat exchange pipe 330 through the connecting pipe 320 to exchange heat with the accommodation cavity 110. The heat exchange medium that has absorbed heat returns to the storage box 310 through the connecting pipe 320 again, is refrigerated by the first refrigeration assembly 200, and then enters the heat exchange pipe 330 through the connecting pipe 320 again, repeating in a cycle, so that the second refrigeration assembly 300 can continuously refrigerate the accommodation cavity 110.

[0046] Specifically, a circulation pump 340 can be provided on the circulation loop. The circulation pump 340 can provide power to enable the heat exchange medium to circulate. The heat exchange pipes 330 can be distributed in the box body 100 in a large area and evenly, so as to further improve the temperature uniformity in the accommodation cavity 110 during the heat exchange process. The heat exchange pipes 330 can be arranged in a rectangular, triangular, trapezoidal or other shapes as a whole, and there is no limitation on this. The storage box 310 includes a box body 312 and a box cover 313. The heat exchange medium is stored in the box body 312, and the box cover 313 is detachably covered on the box body 312 to facilitate the replacement of the heat exchange medium. Of course, holes need to be opened on the box body 312 or the box cover 313 to connect with the connecting pipe 320.

[0047] In some embodiments, please refer to Figure 5 , the heat exchange pipe 330 is at least arranged on one side wall 111 of the accommodation cavity 110.

[0048] Obviously, the box body 100 of the refrigerator 1 is in the shape of a cuboid. Therefore, there are four side walls 111 in the box body 100. The heat exchange pipe 330 can be arranged on one, two or more side walls 111, and there is no limitation on this. Of course, the more side walls 111 provided with the heat exchange pipe 330, the better the heat exchange effect and the more uniform the heat exchange.

[0049] In some embodiments, please refer to Figure 1 and Figure 2, the refrigerator 1 further includes a cover plate 113 which covers the side wall 111, and the heat exchange tube 330 is disposed within the cover plate 113.

[0050] An installation space is formed between the cover plate 113 and the side wall 111, and the heat exchange tube 330 is disposed in this installation space. The heat exchange tube 330 can be disposed on the cover plate 113 or on the side wall 111, and there is no limitation in this regard. The cover plate 113 isolates the heat exchange tube 330 from the food materials stored in the accommodation chamber 110, thereby playing a certain protective role for the heat exchange tube 330. It can reduce the corrosion of heat exchange caused by the water vapor generated by the food materials, extend the service life of the heat exchange tube 330, and also, to a certain extent, avoid the heat exchange tube 330 from being knocked when the user takes items in the accommodation chamber 110.

[0051] In some embodiments, an air outlet 114 is provided on the cover plate 113, and a circulation fan 115 is further disposed within the cover plate 113. The circulation fan 115 is correspondingly arranged with the air outlet 114.

[0052] The air outlet 114 is communicated with the accommodation chamber 110, and the circulation fan 115 is correspondingly arranged with the air outlet 114. Therefore, the air blown out by the circulation fan 115 can directly enter the accommodation chamber 110. Thus, during the heat exchange stage, the circulation fan 115 can accelerate the air flow, and further accelerate the speed of heat exchange, improving the heat exchange efficiency.

[0053] Specifically, the more the number of the circulation fans 115, the faster the speed of heat exchange. Therefore, a plurality of air outlets 114 can be provided on the cover plate 113, and each air outlet 114 is correspondingly provided with a circulation fan 115, and the plurality of air outlets 114 can be equally spaced to make the air flow more uniform, thereby improving the temperature uniformity within the accommodation chamber 110.

[0054] Certainly, a plurality of air inlets 116 are also provided on the cover plate 113, that is, after the cold air in the installation groove 112 enters the accommodation chamber 110 through the air outlet 114 for refrigeration, it enters the installation groove 112 again through the air inlets 116 to realize air circulation, thereby realizing heat exchange.

[0055] In some embodiments, the storage box 310 is disposed outside the box body 100.

[0056] Since there is an accommodation chamber 110 for storing items within the box body 100, in order to ensure the volume of the accommodation chamber 110 so that the accommodation chamber 110 can store more items, the storage box 310 is disposed outside the box body 100, so that the storage box 310 does not occupy the space inside the box body 100, providing more space for the setting of the accommodation chamber 110.

[0057] Of course, since the storage box 310 is disposed outside the box body 100, while the heat exchange tube 330 is disposed inside the box body 100, a part of the connecting tube 320 connecting the storage box 310 and the heat exchange tube 330 is disposed outside the box body 100, and a part is disposed inside the box body 100. The connecting tube 320 can be made of materials with poor thermal conductivity such as plastic rubber to reduce the loss of cold quantity when the heat exchange medium flows in the connecting tube 320, while the heat exchange tube 330 can be made of materials with good thermal conductivity such as carbon steel and low alloy steel to improve the heat exchange efficiency.

[0058] In some embodiments, the connecting tube 320 is detachably connected to the heat exchange tube 330.

[0059] For the convenience of repairing or replacing the heat exchange tube 330, the connecting tube 320 is detachably connected to the heat exchange tube 330. Therefore, when the heat exchange tube 330 needs to be repaired or replaced, the connecting tube 320 is separated from the heat exchange tube 330, and then the heat exchange tube 330 can be removed from the box body 100. After the heat exchange tube 330 is repaired or replaced, the connecting tube 320 is connected to the heat exchange tube 330.

[0060] Specifically, the connecting tube 320 and the heat exchange tube 330 can be connected in a detachable manner such as flange connection and ferrule connection, and there is no limitation thereto.

[0061] In some embodiments, please refer to Figure 3 and Figure 4 , the first refrigeration assembly 200 includes a compressor 210, a first heat exchanger 220, a second heat exchanger 230, and a throttling member 240. The compressor 210, the first heat exchanger 220, the throttling member 240, and the second heat exchanger 230 are connected in sequence to form a circulation loop, and the second heat exchanger 230 is disposed inside the storage box 310.

[0062] The refrigeration principle of the first refrigeration assembly 200 is as follows: After the compressor 210 operates, the refrigerant inside is compressed into high-temperature and high-pressure superheated steam, and then discharged from the exhaust port of the compressor 210 and enters the first heat exchanger 220. The first heat exchanger 220 dissipates the heat of the refrigerant to the surrounding air, so that the refrigerant condenses from high-temperature and high-pressure superheated steam into normal-temperature and high-pressure liquid, and then enters the throttling member 240 after passing through the drying filter. The refrigerant enters the throttling member 240 and is throttled and depressurized to become low-temperature and low-pressure refrigerant liquid, and then enters the second heat exchanger 230. In the second heat exchanger 230, the low-temperature and low-pressure refrigerant liquid absorbs the heat of the heat exchange medium in the storage box 310 and vaporizes into saturated gas, so as to achieve the purpose of refrigerating the heat exchange medium. Finally, the low-temperature and low-pressure refrigerant gas enters the compressor 210 through the suction port of the compressor 210, and the refrigerant performs the next cycle under the drive of the compressor 210.

[0063] It should be noted that if the first refrigeration component 200 directly cools the accommodation cavity 110, since the frequency of the compressor during operation may not be stable enough, the cooling effect is unstable, resulting in uneven temperature in the accommodation cavity 110. In the embodiment of the present application, since the first refrigeration component 200 first cools the heat exchange medium in the second refrigeration component 300, and then the second refrigeration component exchanges heat with the accommodation cavity 110, and the heat exchange effect of the heat exchange medium is relatively stable, the temperature uniformity of the accommodation cavity 110 can be improved.

[0064] Specifically, the throttling member 240 is a capillary tube, that is, the refrigerant becomes a low-temperature and low-pressure refrigerant liquid after throttling and depressurizing through the capillary tube. In order to enable the second heat exchanger 230 to achieve a better cooling effect on the heat exchange medium, the second heat exchanger 230 can be directly immersed in the heat exchange medium of the storage box 310. In this way, the heat exchange area between the second heat exchanger 230 and the heat exchange medium is large, and the temperature transfer is relatively uniform, so that the heat exchange efficiency between the second heat exchanger 230 and the heat exchange medium is high. Therefore, in the first refrigeration component 200, the compressor 210 can operate at a low frequency to cool the heat exchange medium, so that the noise generated during the operation of the compressor 210 can be reduced. And because the heat generation is low, the rotational speed of the condenser fan can also be set at a low speed to reduce the noise generated during the operation of the condenser, further achieving the purpose of low noise.

[0065] In some embodiments, the storage box 310 and the compressor 210 are arranged at intervals.

[0066] Since the compressor 210 will lift the low-pressure gas to high pressure during operation, thereby increasing its temperature and energy. In this process, when the refrigerant releases heat, it will make the compressor 210 hot, and the evaporator will cool the heat exchange medium in the storage box 310. Therefore, in order to reduce the heat transferred from the compressor 210 to the storage box 310 to ensure the cooling effect of the heat exchange medium, there should be a gap between the storage box 310 and the compressor 210. The storage box 310 and the compressor 210 can be spaced apart vertically or horizontally, and there is no limitation on this.

[0067] In some embodiments, the refrigerator 1 further includes a radiator 250, and the radiator 250 is arranged between the compressor 210 and the first heat exchanger 220.

[0068] Since the first heat exchanger 220 dissipates the heat of the refrigerant to the surrounding air, causing the refrigerant to condense from high-temperature and high-pressure superheated vapor into normal-temperature and high-pressure liquid, a radiator 250 is provided around the first heat exchanger 220 to accelerate the flow of the air around the first heat exchanger 220, enabling the heat of the refrigerant to dissipate faster, thereby improving the refrigeration efficiency. Moreover, since the radiator 250 is disposed between the compressor 210 and the first heat exchanger 220, the radiator 250 can also accelerate the flow of the air around the compressor 210 at the same time, thereby dissipating heat from the compressor 210 to improve the overheating condition of the compressor 210 during operation.

[0069] Specifically, the radiator 250 can be a cooling fan, and the blowing of the cooling fan can accelerate the air flow, thereby enabling the heat to dissipate faster.

[0070] In some embodiments, please refer to Figure 2 and Figure 5 , the refrigerator 1 further includes a housing 400, and the first refrigeration assembly 200 and the storage box 310 are disposed inside the housing 400.

[0071] The housing 400 can provide protection for the first refrigeration assembly 200 and the storage box 310, to a certain extent, preventing damage to the first refrigeration assembly 200 and the storage box 310 caused by external impurities or human bumps.

[0072] Moreover, since the first refrigeration assembly 200 and the storage box 310 are both integrated into the housing, that is, the respective refrigeration elements for refrigerating the electrical equipment are integrated into an independent module, namely the refrigeration module 500, the first refrigeration assembly 200, the second refrigeration assembly 300 and the housing 400 form the refrigeration module 500, and the refrigeration module 500 can be disposed separately from the electrical equipment. Therefore, for any model of the electrical equipment 1, as long as it is assembled with the refrigeration module 500, the refrigeration of the accommodation cavity 110 can be achieved, that is, one refrigeration module 500 can be matched with multiple models of the electrical equipment 1, thereby improving the versatility of the refrigeration module 500, saving the mold cost in the production and development stage, and the refrigeration module 500 and the electrical equipment 1 can be designed and processed separately and then assembled together, without the need for simultaneous processing, thereby improving the production efficiency.

[0073] Specifically, since the heat exchange tube 330 can be used to exchange heat with the accommodation cavity 110 of the electrical equipment 1, for any model of the electrical equipment 1, after the refrigeration module 500 is assembled onto the electrical equipment 1, as long as the heat exchange tube 330 in the refrigeration module 500 is disposed in the electrical equipment 1, the heat exchange tube 330 can exchange heat with the accommodation cavity 110 of the electrical equipment 1 to achieve the refrigeration function.

[0074] It should be noted that, please refer to Figure 8, since the heat exchange tube 330 in the refrigeration module 500 needs to be arranged in the electrical appliance 1 to exchange heat with the accommodation cavity 110 of the electrical appliance 1, both the refrigeration module 500 and the electrical appliance 1 need to reserve an interface 120 for passing the heat exchange tube 330, and it is necessary to ensure that the shape and size of the interface 120 between the electrical appliance 1 and the heat exchange tube 330 remain unchanged. That is, as long as the shape and size of the interface 120 between the electrical appliance 1 and the heat exchange tube 330 remain unchanged, the volume and shape of the accommodation cavity 110 of the electrical appliance 1 can be arbitrarily changed within the design range, and can be adapted to the refrigeration module 500 provided by the embodiments of the present application.

[0075] In some embodiments, the compressor 210 and the first heat exchanger 220 are arranged side by side in a first direction, and the storage box 310 and the compressor 210 are arranged side by side in a second direction, and the first direction is different from the second direction.

[0076] The first refrigeration assembly 200 includes many components, and each component will occupy a certain space. If the arrangement of each component is improper, it will cause the volume of the housing 400 to be too large, making the installation between the refrigeration module 500 and the electrical appliance 1 inconvenient, and affecting the appearance beauty of the electrical appliance 1. Therefore, compared with the compressor 210, the first heat exchanger 220, and the storage box 310 all arranged in one direction, arranging the compressor 210 and the first heat exchanger 220 side by side in the first direction, and arranging the storage box 310 and the compressor 210 side by side in the second direction, with the first direction different from the second direction, can make the distribution of the compressor 210, the first heat exchanger 220, and the storage box 310 closer, thus occupying less space, making the volume of the housing 400 smaller, making the installation between the refrigeration module 500 and the electrical appliance 1 more convenient, and making the appearance of the electrical appliance 1 neater.

[0077] Specifically, the angle between the first direction and the second direction can be a right angle, an acute angle, etc., and there is no limitation thereto.

[0078] In some embodiments, please refer to Figure 6 and Figure 7 , the first refrigeration assembly 200 is arranged outside the box body 100.

[0079] Since there is an accommodation cavity 110 for storing items in the box body 100, in order to ensure the volume of the accommodation cavity 110 so that the accommodation cavity 110 can store more items, the first refrigeration assembly 200 is arranged outside the box body 100, so that the first refrigeration assembly 200 does not occupy the space inside the box body 100, providing more space for the arrangement of the accommodation cavity 110.

[0080] In some embodiments, please refer to Figure 6 , the first refrigeration assembly 200 is arranged at the top or bottom of the box body 100.

[0081] Since the first refrigeration assembly 200 and the storage box 310 are arranged in the housing 400, that is, the housing 400 is arranged at the top or bottom of the box body 100, the installation of the housing 400 can be facilitated, and the overall appearance of the refrigerator 1 is made more neat and beautiful.

[0082] Of course, please refer to Figure 7 , in other embodiments, the first refrigeration assembly 200 may also be arranged on the side of the box body 100, and there is no limitation thereto.

[0083] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
