[0033] The dual-system vehicle refrigerator usually adopts two evaporators, one of which is located in the freezing refrigeration circuit and the other is located in the refrigeration refrigeration circuit. However, the volume of the vehicle refrigerator is relatively small, and the position of the evaporator is limited. Especially for the vehicle refrigerator in the cabin of the vehicle, the design of the evaporator is more limited due to the limited space.

[0034] The embodiments of the present application provide a dual-system vehicle refrigerator, which shares one evaporator for the freezing refrigeration circuit and the refrigeration refrigeration circuit, and the evaporator is designed with two sets of flow paths, and the freezing refrigeration circuit and the refrigeration refrigeration circuit pass through one set of flow paths respectively, realizing two different temperature zone designs, simplifying the pipeline design of the dual-system vehicle refrigerator, and improving the comfort and convenience of use of the dual-system vehicle refrigerator.

[0035] The following exemplary structure is described in the embodiments of the present application.

[0036] Please refer to Figures 1-2 , Figure 1 is a structure diagram of a first dual-system vehicle refrigerator provided by the embodiments of the present application, Figure 2 is a structure diagram of a second dual-system vehicle refrigerator provided by the embodiments of the present application.

[0037] Please refer to Figures 1-2Embodiments of the present application provide a dual-system vehicle refrigerator 1000. The dual-system vehicle refrigerator 1000 comprises a refrigeration system 100. The refrigeration system 100 comprises a freezing refrigeration circuit L1 and a refrigerating refrigeration circuit L2. The refrigeration system 100 comprises an evaporator 110. The evaporator 110 comprises a first flow path 111 and a second flow path 112. The freezing refrigeration circuit L1 and the refrigerating refrigeration circuit L2 share the evaporator 110, and the first flow path 111 of the evaporator 110 is located in the freezing refrigeration circuit L1, and the second flow path 112 of the evaporator 110 is located in the refrigerating refrigeration circuit L2.

[0038] The dual-system vehicle refrigerator 1000 refers to a vehicle refrigerator that has both refrigerating and freezing functions. Specifically, the refrigeration system 100 of the dual-system vehicle refrigerator 1000 comprises two refrigeration circuits, one of which is a freezing refrigeration circuit, and the other of which is a refrigerating refrigeration circuit. In some embodiments, each refrigeration circuit can comprise a compressor, a condenser, a capillary tube, and an evaporator. The refrigerant circulates in the refrigeration circuit, undergoes phase changes from gas to liquid to gas, and is driven by the compressor and changes in pressure to transfer heat inside the refrigerator to the external environment to achieve cooling. In more detail, the compressor compresses low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant releases heat to the outside environment in the condenser and gradually cools into high-pressure liquid refrigerant. The high-pressure liquid refrigerant is throttled and depressurized by the capillary tube to become low-temperature and low-pressure gaseous-liquid mixed refrigerant. The low-temperature and low-pressure gaseous-liquid mixed refrigerant absorbs heat inside the refrigerator to vaporize in the evaporator, achieving cooling. The low-temperature and low-pressure refrigerant after heat absorption returns to the compressor through the return pipe, and the process is repeated to continuously transfer heat inside the refrigerator.

[0039] Generally, the existing dual-system vehicle refrigerator has a freezing refrigeration circuit and a refrigerating refrigeration circuit, each of which is designed with a separate refrigeration system comprising a compressor, a condenser, a capillary tube, and an evaporator. However, due to the demand for small size of the dual-system vehicle refrigerator, the position of the refrigeration system is also limited during design.

[0040] The dual-system vehicle refrigerator 1000 provided by the embodiments of the present application has a refrigeration system 100 with a freezing refrigeration circuit L1 and a refrigerating refrigeration circuit L2 sharing an evaporator 110, which is beneficial to reduce the volume ratio of the refrigeration system 100 in the dual-system vehicle refrigerator 1000 and simplify the pipeline design of the dual-system vehicle refrigerator 1000. The evaporator 110 comprises a first flow path 111 located in the freezing refrigeration circuit L1 and a second flow path 112 located in the refrigerating refrigeration circuit L2, realizing two different temperature zone designs in one evaporator 110 without affecting the independent operation of the freezing function and the refrigerating function of the dual-system vehicle refrigerator 1000, and improving the comfort and convenience of using the dual-system vehicle refrigerator 1000.

[0041] In some embodiments, please continue to refer to Figure 1 The refrigeration system 100 further comprises a capillary assembly 120. The capillary assembly 120 comprises a first capillary tube 121 and a second capillary tube 122, and the first capillary tube 121 and the second capillary tube 122 are switched by a solenoid valve 130. The first capillary tube 121 is connected to the first flow path 111 of the evaporator 110. The second capillary tube 122 is connected to the second flow path 112 of the evaporator 110, and the solenoid valve 130 is located between the capillary assembly 120 and the condenser 140.

[0042] The capillary assembly 120 functions as a throttling device, and by limiting the flow of refrigerant, the pressure of the high-pressure liquid refrigerant is significantly reduced when flowing through, thereby creating conditions for the evaporation of the refrigerant in the evaporator 110. The solenoid valve 130 is used to switch the flow direction of the refrigerant, control the refrigerant from the condenser 140 into the first capillary tube 121 or the second capillary tube 122, and realize independent temperature control of the dual-system vehicle refrigerator 1000.

[0043] The present application divides the capillary assembly 120 into at least the first capillary tube 121 and the second capillary tube 122, so that the first capillary tube 121 accesses the first flow path 111 of the evaporator 110 and the second capillary tube 122 accesses the second flow path 112 of the evaporator 110, without affecting the independent operation of the freezing function and the refrigeration function of the dual-system vehicle refrigerator 1000, and improves the comfort and convenience of using the dual-system vehicle refrigerator 1000.

[0044] In some embodiments, please continue to refer to Figure 1 The refrigeration system 100 comprises a first transition pipe 151 and a second transition pipe 152. The first capillary tube 121 accesses the first flow path 111 of the evaporator 110 through the first transition pipe 151. The second capillary tube 122 accesses the second flow path 112 of the evaporator 110 through the second transition pipe 152.

[0045] The first transition pipe 151 is arranged between the first capillary tube 121 and the first flow path 111 of the evaporator 110, and is used to reduce the spray noise generated when the refrigerant directly enters the first flow path 111 of the evaporator 110 from the first capillary tube 121. The second transition pipe 152 is arranged between the second capillary tube 122 and the second flow path 112 of the evaporator 110, and is used to reduce the spray noise generated when the refrigerant directly enters the second flow path 112 of the evaporator 110 from the second capillary tube 122.

[0046] The embodiments of the present application reduce the noise generated by the dual-system vehicle refrigerator 1000 through the design of the first transition pipe 151 and the second transition pipe 152, and improve the comfort and convenience of using the dual-system vehicle refrigerator 1000.

[0047] In some embodiments, the average pipe diameter of the first transition pipe 151 is greater than the average pipe diameter of the first capillary pipe 121. The average pipe diameter of the second transition pipe 152 is greater than the average pipe diameter of the second capillary pipe 122.

[0048] In some embodiments, the first transition pipe 151 / second transition pipe 152 can be a pipe material with uniform pipe diameter, or a pipe material with non-uniform pipe diameter. In the case of the first transition pipe 151 / second transition pipe 152 being a pipe material with non-uniform pipe diameter, the first transition pipe 151 / second transition pipe 152 can be a pipe material with smoothly varying pipe diameter, or a pipe material with stepwise varying pipe diameter.

[0049] The pipe diameter of the first transition pipe 151 / second transition pipe 152 refers to the inner diameter of the first transition pipe 151 / second transition pipe 152. The average pipe diameter of the first transition pipe 151 / second transition pipe 152 refers to the average value of all the inner diameters of the first transition pipe 151 / second transition pipe 152.

[0050] The pipe diameter of the first capillary pipe 121 / second capillary pipe 122 refers to the inner diameter of the first capillary pipe 121 / second capillary pipe 122. The average pipe diameter of the first capillary pipe 121 / second capillary pipe 122 refers to the average value of all the inner diameters of the first capillary pipe 121 / second capillary pipe 122.

[0051] The average pipe diameter of the first transition pipe 151 is greater than the average pipe diameter of the first capillary pipe 121, so that when the refrigerant enters the first transition pipe 151 from the first capillary pipe 121, the pressure decreases smoothly and does not drop suddenly, reducing the turbulence and pressure drop during the flow of the refrigerant, thereby reducing the noise generated when the refrigerant enters the evaporator 110, and improving the comfort and convenience of use of the dual-system vehicle refrigerator 1000.

[0052] The average pipe diameter of the second transition pipe 152 is greater than the average pipe diameter of the second capillary pipe 122, so that when the refrigerant enters the second transition pipe 152 from the second capillary pipe 122, the pressure decreases smoothly and does not drop suddenly, reducing the turbulence and pressure drop during the flow of the refrigerant, thereby reducing the noise generated when the refrigerant enters the evaporator 110, and improving the comfort and convenience of use of the dual-system vehicle refrigerator 1000.

[0053] In some embodiments, the average pipe diameter of the first transition pipe 151 is greater than the average pipe diameter of the first capillary pipe 121, and less than the average pipe diameter of the first flow path 111. In some embodiments, the average pipe diameter of the second transition pipe 152 is greater than the average pipe diameter of the second capillary pipe 122, and less than the average pipe diameter of the second flow path 112.

[0054] In some embodiments, the end of the first flow path 111 away from the first capillary pipe 121 and the end of the second flow path 112 away from the second capillary pipe 122 are connected to the compressor 170 through the return pipe 160.

[0055] In some embodiments, the first capillary tube 121 and the second capillary tube 122 are collectively wound on the gas return tube 160 and are respectively connected to the first flow path 111 or the second flow path 112 of the evaporator 110, so as to reduce the occupied volume of the refrigeration system 100 in the dual-system vehicle refrigerator 1000 and facilitate the miniaturization of the dual-system vehicle refrigerator 1000.

[0056] Please refer to Figure 3 , Figure 3 is a structural schematic diagram of a vehicle provided by an embodiment of the present application. It should be noted that, in order to clearly show the freezing cavity, Figure 3 the region where the freezing cavity is arranged is shown in a partially regionally perspective manner.

[0057] In some embodiments, referring to Figure 3 , the dual-system vehicle refrigerator 1000 includes a cabinet 1100 and a door body 1200. The cabinet 1100 includes a freezing cavity 1101 and a refrigerating cavity 1102. The door body 1200 is arranged at an opening of the cabinet 1100 and is used to open and close the freezing cavity 1101 and the refrigerating cavity 1102. The first flow path 111 of the evaporator 110 is arranged on a side wall of the freezing cavity 1101, and the second flow path 112 is arranged on a side wall of the refrigerating cavity 1102.

[0058] Among them, the cabinet 1100 is the core component of the dual-system vehicle refrigerator 1000, and bears the core functions of supporting, heat preservation and storage. The freezing cavity 1101 is an independent temperature control space for the dual-system vehicle refrigerator 1000 to store items at low temperature for a long time. In some embodiments, the temperature in the cavity of the freezing cavity 1101 is usually maintained at -18°C to -20°C. The refrigerating cavity 1102 is an independent temperature control space for the dual-system vehicle refrigerator 1000 to store fresh-keeping items for a short time. In some embodiments, the temperature in the cavity of the refrigerating cavity 1102 is usually maintained at 0°C to -5°C.

[0059] Embodiments of the present application arrange the first flow path 111 of the evaporator 110 on the first region 111a of the side wall of the freezing cavity 1101 and the second flow path 112 on the second region 112a of the side wall of the refrigerating cavity 1102, so as to reduce the distance between the evaporator 110 and the freezing cavity 1101 and the refrigerating cavity 1102. On the one hand, this is conducive to reducing the occupied volume of the refrigeration system 100 in the dual-system vehicle refrigerator 1000 and facilitating the miniaturization of the dual-system vehicle refrigerator 1000. On the other hand, this is conducive to reducing the application power of the dual-system vehicle refrigerator 1000 and reducing the loss.

[0060] In some embodiments, the cabinet 1100 includes a partition plate 1103. The partition plate 1103 is arranged between the freezing cavity 1101 and the refrigerating cavity 1102.

[0061] The partition 1103 is configured to separate the freezing cavity 1101 and the refrigerating cavity 1102.

[0062] The embodiment of the present application separates the freezing cavity 1101 and the refrigerating cavity 1102 through the partition 1103, and simplifies the design complexity of the dual-system vehicle refrigerator 1000.

[0063] In some embodiments, the opening 1100a of the box body 1100 is configured to face the top wall 2001 of the vehicle 2000, and the freezing cavity 1101, the partition 1103, the refrigerating cavity 1102, and the door body 1200 are arranged in sequence along a direction perpendicular to a plane in which the vehicle frame 2002 of the vehicle 2000 is located.

[0064] The opening 1100a of the box body 1100 faces the top wall 2001 of the vehicle 2000, which facilitates the access of the articles, and is conducive to improving the comfort and convenience of the use of the dual-system vehicle refrigerator 1000. The freezing cavity 1101 and the refrigerating cavity 1102 are arranged perpendicular to the plane in which the vehicle frame 2002 of the vehicle 2000 is located, which is conducive to reducing the occupied volume of the dual-system vehicle refrigerator 1000 in the vehicle 2000.

[0065] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of a third dual-system vehicle refrigerator provided by the embodiment of the present application.

[0066] In some embodiments, referring to Figure 4 , the dual-system vehicle refrigerator 1000 further comprises a temperature sensor assembly 200. The temperature sensor assembly 200 comprises a first temperature sensor assembly 210. The first temperature sensor assembly 210 is configured to detect the freezing temperature of the dual-system vehicle refrigerator 1000. The temperature sensor assembly 200 further comprises a second temperature sensor assembly 220. The second temperature sensor assembly 220 is configured to detect the refrigerating temperature of the dual-system vehicle refrigerator 1000.

[0067] The dual-system vehicle refrigerator 1000 further comprises a control assembly 300, which is configured to:

[0068] In response to the freezing temperature of the dual-system vehicle refrigerator 1000 exceeding a threshold value, the freezing refrigeration circuit L1 is turned on.

[0069] In response to the refrigerating temperature of the dual-system vehicle refrigerator 1000 exceeding a threshold value, the refrigerating refrigeration circuit L2 is turned on.

[0070] The temperature sensor assembly 200 is configured to detect the internal temperature of the dual-system vehicle refrigerator 1000. The first temperature sensor assembly 210 and the second temperature sensor assembly 220 are configured to detect the freezing temperature and the refrigeration temperature of the dual-system vehicle refrigerator 1000, respectively, so as to realize independent temperature control of the freezing function and the refrigeration function of the dual-system vehicle refrigerator 1000.

[0071] The control assembly 300 is configured to timely respond to the change of the internal temperature of the dual-system vehicle refrigerator 1000, lock the temperature zone of the dual-system vehicle refrigerator 1000 that needs to be controlled, and timely control the temperature of the locked temperature zone, thereby improving the comfort and convenience of the dual-system vehicle refrigerator 1000.

[0072] In some embodiments, the control assembly 300 is configured to:

[0073] In response to the freezing temperature of the dual-system vehicle refrigerator 1000 exceeding the threshold value, the freezing refrigeration circuit L1 is turned on, and in response to the freezing temperature of the dual-system vehicle refrigerator 1000 reaching the preset temperature, the refrigeration refrigeration circuit L2 is turned on.

[0074] In response to the refrigeration temperature of the dual-system vehicle refrigerator 1000 exceeding the threshold value, the refrigeration refrigeration circuit L2 is turned on, and in response to the refrigeration temperature of the dual-system vehicle refrigerator 1000 reaching the preset temperature, the freezing refrigeration circuit L1 is turned on.

[0075] The control assembly 300 is configured to timely switch the refrigeration circuit to another temperature zone when a signal that the temperature of a certain temperature zone of the dual-system vehicle refrigerator 1000 reaches a preset temperature is received during the refrigeration of the certain temperature zone, which is beneficial to improve the reasonable allocation of energy, reduce the overuse of the use power of the refrigeration system 100, and improve the comfort and convenience of the dual-system vehicle refrigerator 1000.

[0076] The following describes in detail the movement process of the operation.

[0077] For example, the threshold value of the freezing temperature of the dual-system vehicle refrigerator 1000 is -15℃, and the preset temperature of the freezing temperature is -18℃.

[0078] In the use of the dual-system vehicle refrigerator 1000, when the control component 300 receives a signal that the internal temperature of the freezing cavity 1101 reaches or is higher than -15℃, it sends a signal to turn on the freezing refrigeration circuit L1. After the freezing refrigeration circuit L1 is turned on, the internal temperature of the freezing cavity 1101 is continuously lowered. When the internal temperature of the freezing cavity 1101 is lower than -18℃, the control component 300 receives a signal that the internal temperature of the freezing cavity 1101 is lower than -18℃, and sends a signal to turn off the freezing refrigeration circuit L1 and turn on the refrigerating refrigeration circuit L2. The refrigerating refrigeration circuit L2 is turned on.

[0079] For example, the threshold value of the refrigerating temperature of the dual-system vehicle refrigerator 1000 is 5℃, and the preset temperature of the freezing temperature is 3℃.

[0080] In the use of the dual-system vehicle refrigerator 1000, when the control component 300 receives a signal that the internal temperature of the freezing cavity 1101 reaches or is higher than -15℃, it sends a signal to turn on the freezing refrigeration circuit L1. After the freezing refrigeration circuit L1 is turned on, the internal temperature of the freezing cavity 1101 is continuously lowered. When the internal temperature of the freezing cavity 1101 is lower than -18℃, the control component 300 receives a signal that the internal temperature of the freezing cavity 1101 is lower than -18℃, and sends a signal to turn off the freezing refrigeration circuit L1 and turn on the refrigerating refrigeration circuit L2. The refrigerating refrigeration circuit L2 is turned on.
