[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0038] Existing dual-temperature cabinets generally have an upper box that can achieve dual temperature zones, and a lower box that is only cold. That is, the upper and lower boxes share a refrigeration system, and a heating device is added to the upper box. The operating mode is upper box cooling plus lower box cooling, or upper box heating plus lower box cooling. The lower box of the dual-temperature cabinet only has a cooling mode, and cannot achieve heating, and the operating mode is single.

[0039] Combination Figures 1 to 4 As shown, a dual-temperature cabinet provided in an embodiment of the present disclosure can enable the first box body 10 and the second box body 20 to both have a cooling mode and a heating mode.

[0040] Optionally, combined Figure 1 As shown, the dual-temperature cabinet includes a first box body 10, a second box body 20, a first heating device 11, a first refrigeration module, a second heating device 21 and a second refrigeration module. The first heating device 11 is arranged in the first box body 10 to achieve heating of the first box body 10; the first refrigeration module is arranged in the first box body 10 to achieve cooling of the first box body 10; the second heating device 21 is arranged in the second box body 20 to achieve heating of the second box body 20; the second refrigeration module is arranged in the second box body 20 to achieve cooling of the second box body 20.

[0041] By setting the first heating device 11 and the first refrigeration module in the first box 10, the first box 10 can have both heating and refrigeration functions. By setting the second heating device 21 and the second refrigeration module in the second box 20, the second box 20 can have both heating and refrigeration functions. The two boxes can realize the following operating modes: cooling of the first box 10 plus cooling of the second box 20; heating of the first box 10 plus cooling of the second box 20; cooling of the first box 10 plus heating of the second box 20; heating of the first box 10 plus heating of the second box 20. The cooling mode and heating mode of the first box 10 and the second box 20 do not interfere with each other, thereby enriching the operating modes of the dual-temperature cabinet.

[0042] Optionally, the first refrigeration module and the second refrigeration module are two independent refrigeration modules to achieve independent refrigeration of the first box 10 and the second box 20 .

[0043] In the prior art, the two boxes of the dual temperature cabinet share a refrigeration module, that is, the upper box evaporator and the lower box evaporator are respectively arranged in the upper box and the lower box, and the upper box and the lower box share a refrigeration pipeline. The refrigerant flows through the upper box or the lower box in the refrigeration pipeline to achieve refrigeration of the upper box and the lower box. However, when the upper box and the lower box are refrigerated at the same time, the refrigerant is easily unevenly distributed in the upper box or the lower box, affecting the refrigeration effect of the upper box and the lower box.

[0044] In the embodiment of the present disclosure, a first refrigeration module is provided in the first box body 10, and a second refrigeration module is provided in the second box body 20. The first refrigeration module and the second refrigeration module are independent of each other, so that the first box body 10 and the second box body 20 can be independently refrigerated to ensure the refrigeration effect of the first box body 10 and the second box body 20.

[0045] Optionally, the first heating device 11 and the second heating device 21 are both positive temperature coefficient heaters (Positive Temperature Coefficient, PTC). The PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and energy-saving electric heater with excellent safety performance.

[0046] Optionally, the first box body 10 is provided with a first air duct, and the dual temperature cabinet also includes a first fan 15, which is arranged in the first air duct and corresponds to the first heating device 11 and the first refrigeration module, and is used to drive air to flow to the first heating device 11 and the first refrigeration module, and flow out from the first air duct after heat exchange with the first heating device 11 and the first refrigeration module.

[0047] An air outlet is provided in the first box 10, and the air outlet is communicated with the first air duct. The first fan 15 is provided in the first air duct and is communicated with the first air duct. After the first fan 15 drives the airflow to exchange heat with the first heating device 11, a hot air flow is formed, and the hot air flow is driven to pass through the first air duct and be discharged from the air outlet to the cabinet space of the first box 10, so as to achieve heating of the first box 10. The first fan 15 drives the airflow to exchange heat with the first refrigeration module to form a cold air flow, and drives the cold air flow to pass through the first air duct and be discharged from the air outlet to the cabinet space of the first box 10, so as to achieve cooling of the first box 10.

[0048] The first heating device 11 and the first refrigeration module share the first fan 15 and the first air duct, which reduces the number of fans and air ducts, makes the internal space of the first box 10 more compact, reduces the occupied area of ​​the fans and air ducts, and improves the volume ratio.

[0049] Optionally, combined Figure 2As shown, the second box body 20 is provided with a second air duct, and the dual temperature cabinet also includes a second fan 25, which is arranged in the second air duct and corresponds to the second heating device 21 and the second refrigeration module, and is used to drive air to flow to the second heating device 21 and the second refrigeration module, and flow out from the second air duct after heat exchange with the second heating device 21 and the second refrigeration module.

[0050] An air outlet is provided in the second box 20, and the air outlet is communicated with the second air duct. The second fan 25 is provided in the second air duct and communicated with the second air duct. After the second fan 25 drives the airflow through the second air duct to exchange heat with the second heating device 21, a hot air flow is formed, and the hot air flow is driven through the second air duct to be discharged from the air outlet to the cabinet space of the second box 20, so as to achieve heating of the second box 20. The second fan 25 drives the airflow through the second air duct to exchange heat with the second refrigeration module, to form a cold air flow, and the cold air flow is driven through the second air duct to be discharged from the air outlet to the cabinet space of the second box 20, so as to achieve cooling of the second box 20.

[0051] The second heating device 21 and the second refrigeration module share the second fan 25 and the second air duct, which reduces the number of fans and air ducts, makes the internal space of the second box body 20 more compact, reduces the occupied area of ​​the fans and air ducts, and improves the volume ratio.

[0052] Optionally, the first refrigeration module includes a first refrigeration pipeline 12 and a first evaporator 13 arranged in the first refrigeration pipeline 12; the second refrigeration module includes a second refrigeration pipeline 22 and a second evaporator 23 arranged in the second refrigeration pipeline 22; wherein the first refrigeration pipeline 12 is not connected to the second refrigeration pipeline 22.

[0053] The evaporator achieves cooling by evaporating the refrigerant and absorbing the surrounding heat.

[0054] The first refrigeration module includes a first refrigeration pipeline 12 and a first evaporator 13 disposed in the first refrigeration pipeline 12. A refrigerant flows in the first refrigeration pipeline 12. When the refrigerant flows to the first evaporator 13, it evaporates through the first evaporator 13 to achieve refrigeration of the first box 10. The second refrigeration module includes a second refrigeration pipeline 22 and a second evaporator 23 disposed in the second refrigeration pipeline 22. A refrigerant flows in the second refrigeration pipeline 22. When the refrigerant flows to the second evaporator 23, it evaporates through the second evaporator 23 to achieve refrigeration of the second box 20.

[0055] The first refrigeration pipeline 12 is not connected to the second refrigeration pipeline 22, so that the refrigerant in the first refrigeration pipeline 12 does not contact the refrigerant in the second refrigeration pipeline 22. In this way, when the first box 10 and the second box 20 need to be refrigerated at the same time, the refrigerant can flow evenly in the first refrigeration pipeline 12 and the second refrigeration pipeline 22 respectively, ensuring the refrigeration effect of the first box 10 and the second box 20. In the dual-temperature cabinet in the prior art, the refrigeration pipelines of the upper box and the lower box are interconnected and arranged in parallel, and the refrigerant flows in the refrigeration pipelines of the upper box and the lower box, which may cause uneven distribution of the refrigerant in the upper box and the lower box, affecting the refrigeration effect of the upper box or the lower box.

[0056] Optionally, the dual temperature cabinet further includes a first compressor 14 and a second compressor 24 , wherein the first compressor 14 is connected to the first refrigeration pipeline 12 ; and the second compressor 24 is connected to the second refrigeration pipeline 22 .

[0057] Optionally, the first compressor 14 is disposed in the first box 10 , and the second compressor 24 is disposed in the second box 20 .

[0058] The refrigeration principle of the dual temperature cabinet is that the first compressor 14 compresses the refrigerant (usually ammonia, Freon, etc.) into high-pressure gas, which enters the condenser 16 and releases heat to the surrounding environment through the radiator. Then the high-pressure liquid refrigerant enters the first capillary 18 or the throttling device to reduce the pressure, and finally enters the first evaporator 13 to start evaporation, absorbing the surrounding heat to achieve refrigeration. The refrigerant after passing through the evaporator will flow through the first evaporator 13 again, and the cycle will continue. The working process of the second compressor 24 is similar to that of the first compressor 14, and will not be described here one by one.

[0059] By providing the first compressor 14 and the second compressor 24 , the refrigerant can be compressed, the pressure and temperature of the refrigerant can be improved, and the circulation of the refrigerant in the first refrigeration pipeline 12 or the second refrigeration pipeline 22 can be promoted.

[0060] In the prior art, a compressor is provided in the upper box or the lower box of the dual temperature cabinet, and the compressor promotes the circulation of the refrigerant in the refrigeration pipeline of the upper box or the refrigeration pipeline of the lower box. In this embodiment, a first compressor 14 is provided in the first box 10, and a second compressor 24 is provided in the second box 20. The first compressor 14 promotes the refrigeration of the first box 10 to achieve uniform flow of the refrigerant in the first refrigeration pipeline 12; the second compressor 24 promotes the refrigeration of the second box 20 to achieve uniform flow of the refrigerant in the second refrigeration pipeline 22, so that the first refrigeration module and the second refrigeration module can be independently refrigerated, ensuring the refrigeration effect of the first box 10 and the second box 20.

[0061] Optionally, the dual temperature cabinet also includes a control unit, which is connected to the first compressor 14, the first heating device 11, the second compressor 24 and the second heating device 21 to control the first compressor 14, the first heating device 11, the second compressor 24 and the second heating device 21 to operate independently.

[0062] When the control unit controls the first compressor 14 to work, the first box 10 can be cooled; when the control unit controls the second compressor 24 to work, the second box 20 can be cooled; when the control unit controls the first heating device 11 to work, the first box 10 can be heated; when the control unit controls the second heating device 21 to work, the second box 20 can be heated.

[0063] The control unit includes a controller, which is connected to the first compressor 14, the first heating device 11, the second compressor 24 and the second heating device 21, so that the first box 10 has a dual temperature control mode of cooling and heating, and the second box 20 also has a dual temperature control mode of cooling and heating, enriching the operation mode of the dual temperature cabinet.

[0064] Optionally, combined Figure 3 As shown, the dual temperature cabinet also includes a condenser 16, which includes a first condensation pipeline 161, and the first condensation pipeline 161 includes a first inlet 1611 and a first outlet 1612; the first inlet 1611 and the first outlet 1612 are respectively connected to the two ends of the first refrigeration pipeline 12; the condenser 16 also includes a second condensation pipeline 261, and the second condensation pipeline 261 includes a second inlet 2611 and a second outlet 2612; the second inlet 2611 and the second outlet 2612 are respectively connected to the two ends of the second refrigeration pipeline 22.

[0065] Optionally, the proportion of the area of ​​the first condensation pipeline 161 and the area of ​​the second condensation pipeline 261 in the total area of ​​the condenser 16 corresponds to the heat load of the first box body 10 and the second box body 20. The greater the heat load, the greater the proportion.

[0066] The first condensation pipeline 161 is used to realize cooling of the first box 10, and the second condensation pipeline 261 is used to realize cooling of the second box 20. The first condensation pipeline 161 and the second condensation pipeline 261 are arranged in the same condenser 16, which reduces the occupied area of ​​the condenser 16 while ensuring normal cooling of the first box 10 and the second box 20.

[0067] The proportion of the area of ​​the first condensation pipeline 161 and the area of ​​the second condensation pipeline 261 in the total area of ​​the condenser 16 corresponds to the heat load of the first box 10 and the second box 20. For example, if the heat load of the first box 10 is large, the proportion of the area of ​​the first condensation pipeline 161 in the total area of ​​the condenser 16 is large. In this way, the pipeline area of ​​the condenser 16 can be adapted to the heat load of its box, ensuring the cooling effect of the first box 10 and the second box 20.

[0068] Optionally, the dual temperature cabinet also includes a water receiving box 30; a first exhaust connecting pipe 17 is provided between the first refrigeration module and the first condensation pipeline 161; a second exhaust connecting pipe 27 is provided between the second refrigeration module and the second condensation pipeline 261; the first exhaust connecting pipe 17 and the second exhaust connecting pipe 27 are both provided in the water receiving box 30.

[0069] Optionally, the first box body 10 is provided with a first drain pipe, and the first drain pipe is communicated with the water receiving box 30 ; the second box body 20 is provided with a second drain pipe, and the second drain pipe is communicated with the water receiving box 30 .

[0070] The first drain pipe and the second drain pipe share the same water receiving box 30 and simultaneously drain water to the water receiving box 30. This reduces the occupied area of ​​the water receiving box 30.

[0071] The first exhaust connection pipe 17 is provided between the first compressor 14 and the first condensation pipeline 161. When the high-temperature and high-pressure refrigerant generated by the first compressor 14 flows through the first exhaust connection pipe 17, it will pass through the water receiving box 30, thereby using the high-temperature refrigerant to accelerate the evaporation of water in the water receiving box 30. Similarly, the second exhaust connection pipe 27 is provided between the second compressor 24 and the second condensation pipeline 261. When the high-temperature and high-pressure refrigerant generated by the second compressor 24 flows through the second exhaust connection pipe 27, it will pass through the water receiving box 30, thereby using the high-temperature refrigerant to accelerate the evaporation of water in the water receiving box 30. The first exhaust connection pipe 17 and the second exhaust connection pipe 27 pass through the water receiving box 30 at the same time, which can further accelerate the evaporation of water in the water receiving box 30.

[0072] Optionally, the first housing 10 is further provided with a first drying filter 19 and a first capillary tube 18 , and the first drying filter 19 and the first capillary tube 18 are connected to the first refrigeration pipeline 12 .

[0073] Optionally, the second box body 20 is further provided with a second drying filter 29 and a second capillary tube 28 , and the second drying filter 29 and the second capillary tube 28 are in communication with the second refrigeration pipeline 22 .

[0074] The first drying filter 19 is provided to filter impurities and dust in the refrigerant and absorb moisture. The first capillary tube 18 is provided to reduce the pressure of the refrigerant. The second drying filter 29 and the second capillary tube 28 have the same effect as the first drying filter 19 and the first capillary tube 18, and will not be described in detail again.

[0075] The dual temperature cabinet provided by the embodiment of the present disclosure can achieve the following technical effects: the dual temperature cabinet includes a first box 10, a second box 20, a first heating device 11, a first refrigeration module, a second heating device 21 and a second refrigeration module, the first heating device 11 is arranged in the first box 10 to achieve heating of the first box 10; the first refrigeration module is arranged in the first box 10 to achieve cooling of the first box 10; the second heating device 21 is arranged in the second box 20 to achieve heating of the second box 20; the second refrigeration module is arranged in the second box 20 to achieve cooling of the second box 20. In this way, four operating modes can be achieved, namely, cooling of the first box 10 and cooling of the second box 20, cooling of the first box 10 and heating of the second box 20, heating of the first box 10 and cooling of the second box 20, and heating of the first box 10 and heating of the second box 20, thereby enriching the operating modes of the dual temperature cabinet and facilitating user use.
