[0002] Currently, car refrigerators typically employ a single refrigeration space structure, which cannot meet users' needs for partitioned storage space or separate refrigeration and freezing functions. In existing technologies, some car refrigerators use partitions to divide the space into different zones, allowing users to easily categorize and place different items. For example, patent document CN222783787U discloses a car refrigerator with freely partitionable compartments. This refrigerator includes a body with a storage cavity inside. A partition is installed within the storage cavity to divide the area within the cavity. Slide rails, elongated and extending laterally, are provided on the front and rear side walls of the storage cavity, and sliders are slidably connected to the slide rails. The front and rear sides of the partition are fixedly connected to the sliders, allowing the partition to move left and right within the storage cavity via the sliders, facilitating the placement of items of different sizes and achieving space partitioning. However, this does not provide separate refrigeration and freezing functions. Utility Model Content

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Given that current vehicle refrigerators generally adopt a single refrigeration space design, it is difficult to meet users' needs for partitioned storage space and separate refrigeration and freezing functions. To address this issue, this utility model of vehicle refrigerator introduces a partitioned air duct structure. Through a complete air duct system design, it not only effectively achieves space division but also fully meets users' diverse needs for multi-functional and multi-space storage.

[0019] like Figure 1 , Figure 2 and Figure 5 As shown, the vehicle refrigerator of this utility model mainly includes a refrigerator body 1 with a accommodating space, an air duct cover 2 that divides the accommodating space into a refrigeration chamber and a refrigerator compartment, a partition assembly 3 that divides the refrigerator compartment into different temperature zones, and a refrigeration assembly 4 disposed in the refrigeration chamber; wherein, the air duct cover 2 is provided with a cover air outlet 21 for cold air to flow out of the refrigeration chamber, and a return air outlet connecting the refrigeration chamber with each temperature zone; the partition assembly 3 is provided with an air supply duct for supplying air to each temperature zone, and each air supply duct is selectively connected to the cover air outlet 21.

[0020] This vehicle-mounted refrigerator achieves flexible separation of different temperature zones by incorporating a partition assembly 3 and an air duct cover 2. The partition assembly 3 has a built-in air duct that divides the refrigerator compartment into multiple independent temperature zones. The air duct cover 2 not only effectively isolates the refrigeration unit 4 from the refrigerator compartment but also works in conjunction with the partition assembly 3 to construct a complete air duct system structure. This allows the temperature of each zone to be independently controlled, enabling the selection of some zones as refrigeration zones and others as freezing zones, thus achieving independent zoning of refrigeration and freezing functions.

[0021] The partition assembly 3 can be integrated with the duct cover 2 or detachably connected to the duct cover 2.

[0022] Preferably, the partition assembly 3 is detachably mounted on the air duct cover 2. After removing the partition assembly 3, the entire refrigerator compartment is used as a single temperature zone, activating either full refrigeration or full freezing mode. Users can flexibly choose to install or remove the partition assembly 3 according to the volume of the stored items and the required storage temperature. This not only enables independent partitioning of refrigeration and freezing functions but also allows the entire space to be flexibly switched to full refrigeration or full freezing mode, providing multi-functional and multi-space usage options. This fully meets users' needs for multi-functional and multi-space vehicle refrigerators, significantly improving the convenience and comfort of use.

[0023] It should be understood that the number of temperature zones in the refrigerator compartment can be flexibly set according to actual needs. The refrigerator compartment can be divided into two temperature zones by one partition assembly 3, or it can be divided into more temperature zones by two or more partition assemblies 3.

[0024] For ease of explanation, the following will use a partition assembly 3 to divide the refrigerator compartment into two temperature zones as an example for detailed explanation. These two temperature zones are designated as a first temperature zone 51 and a second temperature zone 52. One of the first temperature zone 51 and the second temperature zone 52 serves as the refrigerator compartment, and the other as the freezer compartment.

[0025] like Figure 2 and Figure 7 As shown, the partition assembly 3 includes a partition shell, an air duct plate 33 disposed within the partition shell, and a double air damper component 34 disposed on the air duct plate; wherein, the two sides of the air duct plate 33 together with the partition shell form two air supply ducts, and the double air damper component 34 has two air dampers that can be opened and closed independently, each air damper being located within the corresponding air supply duct.

[0026] This design makes the overall structure of the partition assembly 3 more compact, which can not only effectively separate the independent first temperature zone 51 and second temperature zone 52, but also occupy a smaller area, thereby ensuring that both the first temperature zone 51 and the second temperature zone have sufficient storage space.

[0027] In practical applications, the storage space sizes of the first temperature zone 51 and the second temperature zone 52 can be equal or unequal. Depending on the actual volume requirements of the items, the specific installation position of the partition assembly 3 on the air duct cover 2 can be set as needed, thereby dividing the first temperature zone 51 and the second temperature zone 52 into appropriately sized zones.

[0028] In the partition assembly 3, the partition shell can be an integrated structure or a detachable assembly structure.

[0029] Preferably, the partition housing includes a detachably connected partition cover 32 and a partition base 31, which together cover the outside of the air duct plate 33.

[0030] At the same time, see also Figures 7 to 10 In the partition assembly 3, the two air supply ducts are the first air supply duct and the second air supply duct. The first air supply duct and the second air supply duct share an air inlet 61. The air inlet 61 is located on the partition base 31 and is connected to the cover air outlet 21. The first air supply duct also includes a first air supply body 62 located on the side of the air supply plate 33 facing the partition cover 32 and a first air supply outlet 63 penetrating the partition cover 32. The second air supply duct also includes a second air supply body 64 located on the side of the air supply plate 33 facing the partition base 31 and a second air supply outlet 65 penetrating the partition base 31.

[0031] The dual-damper component 34 has two dampers, a first damper and a second damper. The first damper is located on the first air duct body 62 near the air duct inlet 61, and the second damper is located on the second air duct body 64 near the air duct inlet 61. This dual-damper component 34 adopts a staggered dual-damper structure, which can control not only the connection and disconnection between the first air supply duct and the cover plate outlet 21, but also the connection and disconnection between the second air supply duct and the cover plate outlet 21, thereby achieving independent control of the first and second air supply ducts.

[0032] Meanwhile, the return air vents on the duct cover 2 are divided into a first return air vent 22 and a second return air vent 23. The first return air vent 22 connects the cooling chamber to the first temperature zone 51, and the second return air vent 23 connects the cooling chamber to the second temperature zone 52. The specific number of the first return air vent 22 and the second return air vent 23 can be flexibly set according to actual needs.

[0033] like Figure 2 , Figure 3 As shown, after the partition assembly 3 is installed, if the first temperature zone 51 is used as the freezing zone, the first air damper is opened to connect the first air supply duct with the cover air outlet 21. The freezing circulation air path is as follows: refrigeration chamber → cover air outlet 21 → first air supply duct → first temperature zone 51 → first return air outlet 22 → refrigeration chamber.

[0034] like Figure 2 , Figure 4 As shown, after the partition assembly 3 is installed, if the second temperature zone 52 is used as a refrigeration zone, the second air damper is opened to connect the second air supply duct with the cover air outlet 21. The refrigeration circulation air path is as follows: refrigeration chamber → cover air outlet 21 → second air supply duct → second temperature zone 52 → second return air outlet 23 → refrigeration chamber.

[0035] like Figure 6 As shown, after the partition assembly 3 is disassembled, the refrigerator compartment becomes a single freezing zone or a single refrigeration zone, and the entire circulating air path becomes: refrigeration cavity → cover air outlet 21 → refrigerator compartment → first return air outlet 22, second return air outlet 23 → refrigeration cavity.

[0036] like Figure 2 and Figure 7 As shown, the baffle assembly 3 is vertically mounted on the duct cover 2. The baffle faceplate 32 has first air outlets 63 of varying sizes and spacing arranged vertically, and the baffle base 31 has second air outlets 65 of varying sizes and spacing arranged vertically. This design effectively improves the uniformity of airflow from the first and second air outlet ducts, thereby making the temperature distribution in the first temperature zone 51 and the second temperature zone 52 more uniform.

[0037] In practical applications, the dimensions and spacing of the first air outlet 63 and the second air outlet 65 can be flexibly set according to requirements. For example, the main body 62 of the first air duct is approximately U-shaped, and the first air outlets 63 are arranged in two rows along the transverse direction. The design feature of each row of first air outlets 63 is that the closer they are to the air duct cover plate 2, the smaller their size and the larger the spacing. Similarly, the main body 64 of the second air duct is approximately U-shaped, and the second air outlets 65 are arranged in two rows along the transverse direction. The design feature of each row of second air outlets 65 is that the closer they are to the air duct cover plate 2, the smaller their size and the larger the spacing.

[0038] like Figure 7 As shown, the duct plate 33 also has a limiting groove 330 and a duct cover 35. The double damper component 34 is engaged in the limiting groove 330 and fixed to the duct plate 33 by the duct cover 35. This design allows the double damper component 34 to be limited by the limiting groove 330 of the duct plate 33. After the double damper component 34 is installed into the limiting groove 330 of the duct plate 33, the double damper component 34 and the duct plate 33 together form a gap. The duct cover 35 is then used to fill the gap to ensure that the double damper component 34 is securely fixed to the duct plate 33.

[0039] In addition, the air duct plate 33 can be made of EPS material or other insulation materials with thermal insulation properties to form an insulation layer in the temperature zones on both sides separated by the partition assembly 3, so as to ensure that the temperatures on both sides do not interfere with each other.

[0040] like Figure 7As shown, one of the partition cover 32 and the partition base 31 is provided with a partition slot 320, and the other is provided with a partition slot 320. Preferably, the partition cover 32 is provided with a partition slot 320, and the partition base 31 is provided with a partition buckle 310, which is engaged with the partition slot 320. This design achieves a snap-fit ​​fixed connection between the partition base 31 and the partition cover 32, making the installation and disassembly process simple and efficient, and improving the ease of use.

[0041] In practical applications, the installation steps of the partition assembly 3 are as follows: First, install the double damper component 34 into the limiting groove 330 of the duct plate 33; second, install the duct cover 35 in the empty position formed by the double damper component 34 and the duct plate 33; next, place the duct plate 33 into the receiving cavity of the partition base 31; finally, fasten the partition cover 32.

[0042] like Figure 2 , Figure 11 and Figure 12 As shown, the air duct cover 2 is horizontally disposed inside the refrigerator body 1. One of the air duct cover 2 and the refrigerator body 1 is provided with a cover plate buckle 24, and the other is provided with a cover plate groove. Preferably, the air duct cover 2 is provided with a cover plate buckle 24, and the refrigerator body 1 is provided with a cover plate groove, with the cover plate buckle 24 corresponding to and engaging with the cover plate groove. This design achieves a snap-fit ​​fixed connection between the air duct cover 2 and the refrigerator body 1, making installation and disassembly simple and efficient, and improving ease of use.

[0043] Limiting ribs 25 are arranged at intervals on the side of the air duct cover 2 facing the partition assembly 3, and the bottom of the partition assembly 3 is embedded between the limiting ribs 25. This design limits the partition assembly 3 by using the limiting ribs 25 of the air duct cover 2, effectively preventing the partition assembly 3 from shifting due to shaking during transportation of the vehicle refrigerator, and ensuring that the partition assembly 3 always remains stable.

[0044] Meanwhile, three air outlets 21 are located between the limiting ribs 25, including one central air outlet and two side air outlets. After installing the partition assembly 3, the central air outlet of the cover is connected to the air inlet 61 of the air duct, and only one air outlet 21 exits. After removing the partition assembly 3, the air outlet 21 changes from one to three, allowing for rapid cooling of the entire refrigerator compartment. There are three first return air inlets 22, each corresponding to one of the air outlets 21. Similarly, there are also three second return air inlets 23, each corresponding to one of the air outlets 21.

[0045] In addition, the duct cover 2 can be made of EPS material or other insulation materials with thermal insulation properties.

[0046] like Figure 11 , Figure 12 and Figure 13 As shown, a baffle 26 is provided on the side of the air duct cover 2 facing away from the partition assembly 3. The air outlet side of the fan 42 in the cooling assembly 4 faces the air outlet 21 of the cover. The baffle 26 is located between the fan 42 and part of the return air outlet.

[0047] Specifically, baffle 26 is located between the cover plate air outlet 21 and the second return air outlet 23, and refrigeration component 4 is located on the side of baffle 26 facing away from the second return air outlet 23. Refrigeration component 4 mainly consists of an evaporator 41 and a fan 42 arranged side by side, with the evaporator 41 closer to the first return air outlet 22, and the fan 42 closer to the baffle 26 and the cover plate air outlet 21. Since the first temperature zone 51 is closer to the refrigeration component 4, the first temperature zone 51 is designated as the freezing zone, and the second temperature zone 52 as the refrigeration zone. The evaporator 41 is responsible for refrigeration, and the fan 42 delivers cold air through the cover plate air outlet 21 of the duct cover plate 2 to the duct inlet 61 of the partition component 3. By setting baffle 26, it effectively prevents the fan 42 from directly blowing cold air towards the second return air outlet 23, and also effectively prevents the cold air flowing back to the refrigeration chamber from the second temperature zone 52 from directly entering the fan 42 without heat exchange in the evaporator 41.

[0048] like Figure 2 As shown, the refrigerator body 1 is equipped with temperature sensors located in different temperature zones. Specifically, the refrigerator body 1 is equipped with a first temperature sensor 71 located in the first temperature zone 51 and a second temperature sensor 72 located in the second temperature zone 52. By configuring the first temperature sensor 71 and the second temperature sensor 72, the temperatures of the first temperature zone 51 and the second temperature zone 52 are monitored respectively, thereby achieving precise control over the connection or disconnection of the first air duct and the second air duct with the air outlet 21 of the cover plate, and thus effectively regulating the temperatures of the first temperature zone 51 and the second temperature zone 52.

[0049] like Figure 2 and Figure 3 As shown, the refrigerator body 1 includes a cabinet 11 and a door 12. The door 12 is openable and closable on the cabinet 11. Sealing ribs 120 are arranged at intervals on the door 12, and the top of the shelf assembly 3 is embedded between the sealing ribs 120. The sealing ribs 120 on the door 12 seal the shelf assembly 3, ensuring that the cold air in the first temperature zone 51 and the second temperature zone 52 does not circulate with each other, thereby maintaining their respective independent low-temperature environments.

[0050] It should also be noted that the vehicle refrigerator also includes key components such as a compressor, which is located inside the refrigerator body 1 but does not occupy the aforementioned storage space.

[0051] like Figure 1 , Figure 2 and Figure 13As shown, the evaporator 41 and the fan 42 are both located at the bottom of the housing 11. The evaporator 41 is provided with a first screw fixing hole 410 for fixing it to the housing 11; the fan 42 is provided with a second screw fixing hole 420 for fixing it to the housing 11.

[0052] The duct cover 2 is located above the evaporator 41 and the fan 42, and is fixed to the housing 11 by a snap-fit ​​mechanism. The bottom of the partition assembly 3 is snapped between the limiting ribs 25 of the duct cover 2. After the door 12 is closed, the top of the partition assembly 3 is snapped between the sealing ribs 120 of the door 12, thereby forming two independent first temperature zone 51 and second temperature zone 52 inside the vehicle housing 11, with the first temperature zone 51 being closer to the evaporator 41 than the second temperature zone 52. Meanwhile, the inner liner of the housing 11 is respectively equipped with a first temperature sensor 71 located in the first temperature zone 51 and a second temperature sensor 72 located in the second temperature zone 52.

[0053] During operation, the evaporator 41 of the vehicle refrigerator is responsible for cooling. A fan 42 delivers cold air through the air outlet on the duct cover 2 to the air inlet 61 of the partition assembly 3. Subsequently, the first and second air dampers open, respectively, sending cold air into the first duct body 62 and the second duct body 64 within the duct plate 33. Then, the cold air enters the first temperature zone 51 through the first air outlet 63 of the partition cover 32, and simultaneously enters the second temperature zone 52 through the second air outlet 65 of the partition base 31. The cold air in the first temperature zone 51 returns to the cooling chamber through the first return air outlet 22 of the duct cover 2, while the cold air in the second temperature zone 52 returns to the cooling chamber through the second return air outlet 23 of the duct cover 2, and this cycle repeats continuously.

[0054] When the first temperature sensor 71 detects that the temperature of the first temperature zone 51 has reached the set value, the freezer-side damper (i.e., the first damper) closes. Similarly, when the second temperature sensor 72 detects that the temperature of the second temperature zone 52 has reached the set value, the refrigerator-side damper (i.e., the second damper) closes. The compressor then stops.

[0055] If the partition assembly 3 is removed, the three air outlets of the air duct cover 2 will simultaneously release air, and the cold air inside the refrigerator compartment will simultaneously return to the cooling cavity from the first return air inlet 22 and the second return air inlet 23, circulating repeatedly, thereby achieving full refrigeration or full freezing functions. When both the first temperature sensor 71 and the second temperature sensor 72 detect that the temperature of the refrigerator compartment has reached the set value, the compressor stops.

[0056] In summary, the vehicle refrigerator of this utility model adopts a partition air duct structure. Through the complete air duct system design, it not only realizes the separation of space, but also meets the user's multi-functional and multi-space storage needs, improving the user's convenience and comfort.
