[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The following is combined with Figures 1-6 The vehicle-mounted refrigerator of this utility model embodiment will be described.

[0032] Understandably, referring to Figure 1 , Figure 2 and Figure 5 In some examples of this utility model, the vehicle refrigerator includes a cabinet 100, a refrigeration evaporator (not shown in the figure), an ice-making module 200, a solenoid valve (not shown in the figure), a compressor 500, a condenser 600, a cooling fan 700, and a control box assembly 800.

[0033] Reference Figures 1 to 3 In some examples of this utility model, the housing 100 is provided with a chamber 110, which has a refrigeration zone 111 and an ice-making zone 112. A refrigeration evaporator is provided on the housing 100 and is used to output cooling capacity to the refrigeration zone 111.

[0034] It should be noted that the refrigeration zone 111 can hold beverages and other foods that require refrigeration; the vehicle refrigerator also includes a lid, which is movably mounted on the upper surface of the chamber 110. Specifically, the lid can be mounted on the upper surface of the chamber 110 by rotating, sliding, or as a separate unit.

[0035] Reference Figure 3 and Figure 4 An ice-making module 200 is located in the ice-making area 112. The ice-making module 200 includes an ice-making box 210 and an ice-making evaporator 220. The ice-making box 210 is provided with an ice-making trough 211. The ice-making box 210 and the ice-making evaporator 220 are fitted together. The ice-making box 210 is detachably located in the ice-making area 112.

[0036] It should be noted that, referring to Figure 4 In some examples of this utility model, the ice-making tank 211 is square in shape, but it can also be round, triangular, etc.

[0037] The vehicle refrigerator uses an ice-making module 200 to make ice through an ice box 210 and an ice evaporator 220, so that the vehicle refrigerator has both cooling and ice-making functions.

[0038] The ice maker 210 is tightly fitted to the ice evaporator 220, enabling cold air transfer for ice making. This fully utilizes the low temperature of the ice evaporator 220, improving heat exchange efficiency and thus accelerating ice making. The tight fit avoids heat loss caused by hollow or gap-like structures, helping to reduce energy consumption. Furthermore, when adding water, the user can directly remove the ice maker 210, preventing water splashing and making the process simpler and more hygienic. After ice making, the entire ice maker 210 can be removed for pouring or use, simplifying the process. Therefore, the car refrigerator combines the high-efficiency ice making of the ice evaporator 220 with the detachable ice maker 210, improving both ice making efficiency and the convenience of adding water, removing ice, and cleaning, thus enhancing the user experience.

[0039] Understandably, referring to Figure 3 and Figure 4 In some examples of this utility model, the ice evaporator 220 includes a plate portion 221 and a tube portion 222 connected to the plate portion 221, and the side wall of the plate portion 221 away from the tube portion 222 is fitted to the ice box 210.

[0040] With the above structure, it can be understood that the ice-making evaporator 220 is a plate-tube evaporator. The side wall of the plate part 221 of the ice-making evaporator 220 away from the tube part 222 is in close contact with the ice box 210. Since the plate part 221 is in close and direct contact with the ice box 210, the loss of cold energy transfer is small, the ice-making speed is significantly improved, the ice-making cycle is shortened, and the demand for rapid ice making is met. The tube part 222 and the plate part 221 are tightly combined, and the far end of the plate is in close contact with the ice box 210, which makes the overall structure of the entire ice-making module 200 more compact and the component layout optimized, which is beneficial to the space design of refrigerators, ice makers and other equipment.

[0041] Of course, in some other examples, the ice-making evaporator 220 described above can also be a finned evaporator.

[0042] Understandably, referring to Figure 2 and Figure 3 In some examples of this utility model, the refrigeration zone 111 and the ice-making zone 112 are distributed vertically along the interior of the chamber 110.

[0043] The ice-making zone 112 and the refrigeration zone 111 are arranged vertically, which makes more efficient use of the space inside the chamber 110, facilitates the rational division of different functional areas, and results in a compact structure.

[0044] Cold air naturally sinks, and placing the ice-making zone 112 below the refrigeration zone 111 allows more cold energy to naturally accumulate in the ice-making zone 112, thereby accelerating the ice-making speed and improving ice-making efficiency.

[0045] Reference Figure 2 and Figure 3 In some examples of this utility model, the vehicle refrigerator also includes a partition 120, which is movably connected to the cabinet 100. The partition 120 is located in the lower part of the cavity 110 and between the cooling zone 111 and the ice-making zone 112. The partition 120 is correspondingly arranged above the ice-making box 210. The partition 120 is movable relative to the box 100 to avoid or cover the ice container 210.

[0046] With the above configuration, when a user places beverages or other food in the refrigeration zone 111, the partition 120 provides certain support. Furthermore, by moving the partition 120 to directly expose the ice maker 210, the user can quickly remove the ice maker 210. The partition 120 is precisely aligned with the top of the ice maker 210, avoiding redundant structures occupying vertical space. In addition to the above, the partition 120 can also position the ice maker 210, restricting its vertical movement relative to the ice-making zone 112.

[0047] Of course, in some examples, the aforementioned partition plate 120 can also be set as a plate for transferring cold energy, so that when only the ice-making evaporator 220 is turned on, beverages and other foods in the refrigeration zone 111 can share a low-temperature environment to achieve refrigeration; of course, it can also be understood that when the refrigeration evaporator is running, it can also provide a relatively low-temperature environment for the ice-making zone 111 in advance, so as to quickly achieve the ice-making effect, and can achieve the sharing and balance of airflow and cold energy between the refrigeration zone 111 and the ice-making zone 112.

[0048] It should be noted that in some examples of this utility model, the movable connection between the partition plate 120 and the box 100 can be a split-type overlapping connection, a detachable connection, a rotatable connection, or a sliding connection, and no limitation is made here.

[0049] Specifically, in some embodiments, the split-type overlapping connection is provided, such as the cabinet 100 having an overlapping recess between the ice-making zone 112 and the cooling zone 111, with the lower surface of the edge of the partition plate 120 abutting against the upper surface of the overlapping recess. Alternatively, in other examples, the detachable connection is provided, such as a snap-fit ​​connection, where the edge of the partition plate 120 is provided with snaps or protrusions, and the cabinet 100 has corresponding slots or holes, which can be inserted and locked or pressed lightly to fix it, and pulled out in the opposite direction when removed; the rotatable connection is provided, such as the partition plate 120 having a rotating shaft, and the cabinet 100 having a rotating hole, with the rotating shaft and rotating hole rotatably connected, allowing the partition plate 120 to rotate to avoid or cover the ice-making box 210; the slidable connection is provided, such as a guide rail sliding connection, where a pair of guide rails are installed inside the cabinet 100, and the partition plate 120 slides along the guide rails to the desired position and is fixed, allowing the partition plate 120 to move smoothly back and forth, left and right, or up and down.

[0050] It should be noted that in some examples of this utility model, the horizontal area of ​​the partition plate 120 is greater than or equal to the horizontal area of ​​the ice-making zone 112.

[0051] Understandably, referring to Figure 5 and Figure 6 In some other examples of this utility model, the refrigeration zone 111 and the ice-making zone 112 are distributed laterally along the interior of the chamber 110.

[0052] With the above arrangement, the left and right zones are clearly separated, and the refrigeration zone 111 and the ice-making zone 112 can be independently temperature-controlled, improving their respective performance stability. Users can take ice and food without interference; this user-friendly design facilitates simultaneous operation by multiple people, enhancing the ease of use of the device.

[0053] It should be noted that the ice-making zone 112 and the cooling zone 111 can be placed on the left or right side depending on usage habits, thus enhancing the user experience.

[0054] Specifically, in some examples of this utility model, a clearance opening is provided on one side wall inside the chamber 110, and the clearance opening connects the refrigeration zone 111 and the ice-making zone 112.

[0055] With the above arrangement, a clearance opening is provided on the side wall of chamber 110 to connect the cooling zone 111 and the ice-making zone 112. Users can remove the ice container 210 through the clearance opening on one side of the cooling zone 111. This also allows for the sharing and balancing of airflow and cooling capacity between the cooling zone 111 and the ice-making zone 112, optimizing the internal functional layout and improving cooling and ice-making efficiency. Therefore, the lateral clearance opening design achieves multiple optimizations in terms of operational convenience, cooling efficiency, and space utilization while maintaining functional zoning.

[0056] Specifically, refer to Figure 6In some examples of this utility model, the ice box 210 is placed in the ice-making area 112. The ice box 210 and the ice-making area 112 are sized to match. A snap-fit ​​structure 300 for detachable connection between the side wall of the ice-making area 112 and the ice box 210 is provided. It can be operated manually without tools and has a compact structure. The detachable snap-fit ​​structure 300 (such as buckle, hook, slot, etc.) realizes quick connection and separation of the ice-making area 112 and the ice box 210 through elastic deformation or geometric interlocking. It can be understood that the snap-fit ​​structure 300 includes a snap-fit ​​protrusion 310 and an elastic snap-fit ​​plate 320. In some examples of this utility model, the snap-fit ​​protrusion 310 is formed on the side wall of the ice-making area 112, and the elastic snap-fit ​​plate 320 is formed on the side wall of the ice-making box 210. The elastic snap-fit ​​plate 320 is provided with a snap-fit ​​recess that engages with the snap-fit ​​protrusion 310. Of course, in other examples, the snap-fit ​​protrusion 310 can also be formed on the ice-making box 210, and the elastic snap-fit ​​plate 320 can be formed on the side wall of the ice-making area 112.

[0057] Understandably, referring to Figure 4 and Figure 6 In some examples of this utility model, the ice box 210 includes a temperature-conducting box body 212 and a lid 213 covering the temperature-conducting box body 212. The bottom surface of the temperature-conducting box body 212 is attached to the upper surface of the ice evaporator 220, and the ice trough 211 is disposed inside the temperature-conducting box body 212.

[0058] Through a close-fitting design, the ice evaporator 220 acts on the temperature-conducting box 212 of the ice box 210, and the generated low temperature can act more directly and fully on the ice-making tank 211. The ice-making tank 211 is directly placed inside the temperature-conducting box 212, and its bottom is in close contact with the ice evaporator 220, which makes the entire ice-making structure compact and the refrigeration path short, which is conducive to the optimization design of the overall equipment.

[0059] It is understood that in some examples of this utility model, the temperature-conducting box body 212 is a temperature-conducting metal component, and the box cover 213 is a plastic component.

[0060] The heat-conducting metal parts have high thermal conductivity, which can greatly improve the efficiency of cold energy transfer from the ice evaporator 220 to the water in the ice tray, speeding up ice making. They are also structurally robust, and the surface of the heat-conducting metal parts is usually smooth, with good corrosion resistance, making them easy for users to clean and maintain. The plastic lid 213 is easy to mold, and the lid 213 can fit tightly with the heat-conducting box body 212, providing a seal. Some plastics themselves have good thermal insulation properties, which helps to reduce heat transfer from the top and further improve ice making efficiency.

[0061] Specifically, in some examples of this utility model, the temperature-conducting box body 212 is made of aluminum or stainless steel, and the box cover 213 is made of silicone.

[0062] Of course, in other examples, the aforementioned heat-conducting box 212 can also be made of high-molecular composite thermally conductive plastic or a composite material formed by metal and plastic, while the box cover 213 is a rubber part; or the heat-conducting box 212 is a heat-conducting metal part, while the box cover 213 is also a metal cover, or the box cover 213 is a composite material cover, such as metal with an insulation layer, plastic with an insulation layer, etc., which combines strength, heat insulation and lightness, and prevents cold loss.

[0063] Understandably, referring to Figure 1 In some examples of this utility model, the ice-making evaporator 220 and the refrigeration evaporator are respectively connected to a solenoid valve.

[0064] With the above settings, the operation and stop of the refrigeration mode and the ice-making mode are switched by the solenoid valve, that is, the operation and stop of the refrigeration evaporator and the ice-making evaporator 220 are controlled.

[0065] Controlled by solenoid valves, the refrigerant flow to and from the ice-making evaporator 220 and the refrigeration evaporator can be independently controlled, without interference between them. When the user only needs to make ice, the solenoid valve only allows refrigerant to flow to the ice-making evaporator 220, avoiding unnecessary energy consumption of the entire refrigeration system and further reducing power consumption.

[0066] Using an electronic control system, the solenoid valve can automatically switch between cooling and ice-making modes, intelligently determining the required cooling capacity based on ambient temperature or ice storage capacity, significantly improving automation and ease of use; it can effectively avoid risks such as overload or abnormal refrigerant flow caused by simultaneous operation, improving system stability and lifespan.

[0067] Understandably, referring to Figure 1 , Figure 2 and Figure 5 In some examples of this utility model, the compressor 500 is located in the housing 100, and the input end of the compressor 500 is connected to the ice-making evaporator 220 and the refrigeration evaporator; the condenser 600 is located in the housing 100, and the output end of the compressor 500 is connected to the input end of the condenser 600. The output end of the condenser 600 is provided with a first pipe and a second pipe. The first pipe is connected to the ice-making evaporator 220, and the second pipe is connected to the refrigeration evaporator. Both the first and second pipelines are connected to solenoid valves.

[0068] With the above configuration, the refrigerant output from the condenser 600 can be guided to different evaporators, namely the ice-making evaporator 220 or the refrigeration evaporator, through corresponding pipelines under the control of the solenoid valve, thus achieving a fixed refrigerant supply. The solenoid valve can open / close the corresponding passage as needed to achieve dual-path or single-path cooling, providing flexible control to meet different cooling needs. The ice-making evaporator 220 and the refrigeration evaporator can be flexibly switched according to the actual working load of the compressor 500 and each component, avoiding compressor 500 overload and abnormal refrigerant flow, and extending the overall life of the machine.

[0069] It should be noted that in some examples of this utility model, the refrigeration evaporator and the ice-making evaporator 220 are connected to the same solenoid valve, such as a three-way solenoid valve, which has an inlet connected to the output end of the condenser 600 and two outlets, one of which is connected to the first pipeline and the other outlet is connected to the second pipeline.

[0070] Of course, in other examples, two solenoid valves can be connected one-to-one with the refrigeration evaporator and the ice-making evaporator 220 for control; this is not a limitation here. Understandably, referring to Figure 1 , Figure 2 and Figure 5 In some examples of this utility model, the cooling fan 700 and the control box assembly 800 are both located in the housing 100. The cooling fan 700 is located between the compressor 500 and the condenser 600, which enables the airflow on the condenser 600 side to be discharged quickly, increasing the heat dissipation efficiency of the condenser 600 and ensuring stable condensing pressure. Effective cooling of the condenser 600 helps to reduce the load on the compressor 500, lower the operating temperature of the compressor 500, and extend the life of the compressor 500, thereby improving the overall operating efficiency and reliability of the system.

[0071] In some examples of this utility model, the compressor 500, the condenser 600, and the cooling fan 700 are all electrically connected to the control box assembly 800; The compressor 500, condenser 600, and cooling fan 700 are all located on the same side as the control box assembly 800. With the compressor 500, condenser 600, fan, and control box assembly 800 all on the same side, the entire vehicle refrigerator system is centrally located, making electrical connections and piping installation relatively convenient. This helps reduce wiring length and complexity, and maintenance is convenient. All key components are centrally located for easy inspection and maintenance. The compact layout within a limited space saves space for the vehicle refrigerator.

[0072] Alternatively, in some other examples, the compressor 500, condenser 600, and cooling fan 700 are located on one side of the housing 100, while the control box assembly 800 is located on the other side. The independent arrangement of the control box assembly 800, away from heat sources, provides a better temperature environment, which is beneficial for the stable operation of electronic components and extends their lifespan. It should be noted that in some examples of this utility model, the compressor 500, condenser 600, cooling fan 700, and control box assembly 800 are all arranged outside the chamber 110. With this arrangement, the components are installed outside the chamber 110, resulting in good heat dissipation and a relatively clean and tidy internal environment, reducing interference with internal equipment; it also allows for the welding of pipelines while ensuring the sealing performance of the housing 100.

[0073] Understandably, referring to Figure 2 and Figure 3 In some examples of this utility model, the housing 100 includes a first housing 130 and a second housing 140. The first housing 130 and the second housing 140 are fixedly connected by snap-fit, screw connection or other means to ensure that the connection between the housings is stable and reliable and that installation and disassembly are convenient. The specific distance between the first housing 130 and the second housing 140 forms a heat insulation cavity 150 to achieve effective thermal isolation, reduce heat transfer and improve overall heat preservation.

[0074] The first housing 130 has a chamber 110. The ice-making evaporator 220 and the refrigeration evaporator are both installed on the side wall of the first housing 130. The compressor 500, condenser 600, cooling fan 700 and solenoid valve are all installed on the side wall of the second housing 140. The key components are reasonably distributed, which facilitates maintenance and reduces mutual interference, thereby improving the overall performance and stability.

[0075] It should be noted that, referring to Figure 1 In some examples of this utility model, the output end of the condenser 600 is provided with a dryer filter 900. It can be understood that the refrigerant at the output end of the condenser 600 is a high-pressure liquid. When it passes through the dryer filter 900, the moisture and impurities are effectively removed. The clean high-pressure liquid passes through the throttling device (capillary tube / expansion valve), and the pressure and temperature drop sharply, becoming a low-temperature and low-pressure vapor-liquid mixture. The low-temperature and low-pressure vapor-liquid mixture re-enters the evaporator to absorb heat and vaporize again, completing the cycle.
