Technical Field

[0001] This invention belongs to the field of vehicle refrigerator technology, specifically relating to an integrated mixed-flow air-cooling module for a vehicle refrigerator, a vehicle refrigerator, and a vehicle. Background Technology

[0002] The air-cooling module of a car refrigerator is used to circulate cold air inside the refrigerator, achieving a mixed-flow direct cooling effect and improving the uniformity of temperature inside the refrigerator, especially in the humid, enclosed environment. In existing technology, the air-cooling module is usually directly fixed to the back of the refrigerator's inner liner or the evaporator cavity, forming a non-removable integrated structure. This design makes it impossible for users to effectively clean and maintain the fan blades, motor shaft, and air duct inside the air-cooling module during daily use. Professional disassembly and cleaning requires repair, which is cumbersome and costly. Over time, dust, food debris, and condensation easily accumulate on and around the fan blades, forming stubborn dirt. Given the frequent temperature changes and high internal humidity experienced by car refrigerators, this area becomes a breeding ground for mold and bacteria, posing a direct risk of biological contamination to stored food, beverages, or medicines, and presenting a significant hygiene and safety hazard.

[0003] In addition, the accumulation of dirt will increase the fan's rotational resistance, leading to a greater load on the motor. This will not only generate abnormal noise, but also reduce heat dissipation efficiency, affecting the overall cooling effect of the refrigerator, and may shorten the lifespan of the fan. Summary of the Invention

[0009] Furthermore, the fan front cover is provided with a first electrical contact, and the inner side wall of the mounting base is provided with a second electrical contact. When the first electrical contact and the second electrical contact are electrically connected, the vehicle refrigerator supplies power to the air-cooling module.

[0010] Furthermore, a power indicator light is provided on the outer side of the fan front cover, which is used to indicate the working status of the fan body.

[0011] Furthermore, the fan front cover and the fan body enclose a first space, and the fan front cover and the mounting base enclose a second space, with the second space located below the first space; The fan front cover is provided with an air inlet and an air outlet, and the fan body is provided with an adapter located below the first space; Driven by the impeller in the fan body, air is drawn into the first space through the air inlet, and then discharged through the adapter, the second space and the air outlet in sequence.

[0012] Furthermore, a guide plate is provided on the side of the fan front cover near the fan body. The guide plate has a U-shaped structure, and the upper opening of the guide plate is connected to the first space. The area enclosed by the air guide plate corresponds to the second space.

[0013] Furthermore, the fan front cover has an oblique hole on the wall of the second space, and the oblique hole is the air outlet; The air outlet is located below the air inlet and is used to guide the discharged air to be discharged obliquely downward away from the air inlet.

[0014] In another aspect, the present invention provides a vehicle refrigerator, including the above-mentioned integrated mixed-flow air-cooling module, wherein the inner liner side wall of the vehicle refrigerator is provided with a mounting groove, and the mounting base is inserted into the mounting groove.

[0015] A third aspect of the invention provides a vehicle including the aforementioned vehicle-mounted refrigerator.

[0016] In summary, the technical effects achieved by this invention are as follows: The integrated mixed-flow air-cooled module for a vehicle refrigerator provided by this invention includes: a mounting base, detachably embedded in the inner liner of the vehicle refrigerator; a fan front cover, detachably connected to the mounting base, the outer surface of the fan front cover being the outer surface of the air-cooled module; a fan body, installed between the mounting base and the fan front cover, and detachably connected to the fan front cover; the air-cooled module is detachably connected to the vehicle refrigerator via the mounting base; when the vehicle refrigerator needs to enhance its cooling effect, the air-cooled module is installed in the inner liner of the vehicle refrigerator in a plug-and-play manner, using air cooling to provide mixed-flow cooling for the inner liner.

[0018] Specifically, the mounting base, fan front cover, and fan body all feature convenient detachable connections, improving ease of disassembly and assembly during maintenance. When cleaning is required, users can first remove the fan front cover, easily detaching it along with the fan body from the mounting base for initial cleaning of surface dirt on core components such as the fan impeller. For deeper, more thorough cleaning, the fan body can be further separated from the fan front cover, and the mounting base can be completely removed from the refrigerator's inner liner. This design ensures that all components of the air-cooled module, including hidden air ducts, the area around the motor, and mounting surfaces—traditionally hard-to-clean areas—are fully exposed and effectively cleaned.

[0019] This structure allows users to perform thorough cleaning regularly, effectively eliminating the risk of food contamination caused by mold and bacteria growth. It can also be disassembled, cleaned, and restored by itself without the need for professional tools or complicated operations, which greatly reduces maintenance costs and ensures the long-term reliable operation of the equipment. Regular cleaning can prevent dirt buildup from affecting the fan balance and increasing the motor load, thereby maintaining the cooling effect, reducing abnormal noise, and extending the service life of the entire air-cooling system.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] The following combination Figures 1-10 The structure and shape of the integrated mixed-flow air-cooled module for the vehicle refrigerator provided in this embodiment are described in detail below: The integrated mixed-flow air-cooled module for the vehicle refrigerator provided in this embodiment includes a mounting base 100, a fan front cover 200, and a fan body 300, such as Figure 1 As shown, the mounting base 100 and the fan front cover 200, as well as the fan front cover 200 and the fan body 300, are all detachably connected. The mounting base 100 and the vehicle refrigerator 10 are also detachably connected, which enables the air-cooled module to have a plug-and-play installation function, adapt to different cooling needs of the vehicle refrigerator 10, and facilitate cleaning and maintenance.

[0027] Specifically, the mounting base 100 is used to connect and fix the entire air-cooled module 20 to the vehicle refrigerator 10, and also provides mounting support for the fan front cover 200. The mounting base 100 is detachably embedded in the inner liner 11 of the vehicle refrigerator 10. To achieve convenient disassembly and secure positioning of the mounting base 100, the side wall of the inner liner 11 of the vehicle refrigerator 10 is pre-set with a mounting groove 101 that matches the shape of the mounting base 100. The mounting base 100 is inserted into the mounting groove 101. The mounting groove 101 and the mounting base 100 are fitted with a transition fit, which ensures the stability after installation and allows for convenient disassembly and assembly. The mounting base 100 can be inserted and removed without the need for professional tools. Figure 9 , Figure 10 As shown. In addition to the above-mentioned insertion method, the detachable connection between the mounting base 100 and the inner liner 11 of the vehicle refrigerator 10 can also adopt a snap-fit ​​connection structure, that is, an elastic snap is provided on the outer wall of the mounting base 100, and a snap-fit ​​groove is provided at the corresponding position on the inner wall of the mounting groove 101, and the fixation is achieved by the engagement of the elastic snap and the snap-fit ​​groove; or a magnetic connection structure can be adopted, with permanent magnets and metal pieces adsorbed on the mating surfaces of the mounting base 100 and the mounting groove 101 respectively, to achieve quick disassembly and positioning.

[0028] To ensure accurate positioning during the insertion of the mounting base 100 and prevent misalignment of components due to insertion misalignment, a positioning port 270 is provided at the lower part of the fan front cover 200, and a positioning block 120 that mates with the positioning port 270 is provided on the mounting base 100. The positioning block 120 has a cuboid structure, and the positioning port 270 has a groove structure that matches the shape of the positioning block 120. The positioning block 120 and the positioning port 270 are fitted with a clearance. When the fan front cover 200 and the mounting base 100 are connected, the positioning block 120 is first inserted into the positioning port 270 to achieve pre-positioning of the two, which facilitates the precise connection of the subsequent connection structure. At the same time, it can also help improve the overall flatness after the two are connected, and prevent the fan body 300 from tilting due to misalignment. In addition to the aforementioned matching structure of the cuboid positioning block 120 and the groove positioning opening 270, the positioning structure can also adopt the matching form of positioning pin and positioning hole, that is, a cylindrical positioning pin is set on the mounting base 100, and a positioning hole is set at the corresponding position on the fan front cover 200, and the positioning pin is inserted into the positioning hole to achieve pre-positioning; or a trapezoidal positioning block 120 and a trapezoidal groove can be used to match. The trapezoidal structure has a guiding function, which can further improve the convenience of docking, and at the same time prevent lateral displacement after docking.

[0029] In this embodiment, the fan front cover 200 not only protects the fan body 300, but its outer surface also serves as the exterior surface of the air-cooling module, directly contacting the internal environment of the inner liner 11 of the vehicle refrigerator 10. Therefore, the fan front cover 200 is made of antibacterial plastic that is compatible with the material of the inner liner 11 of the vehicle refrigerator 10, ensuring both aesthetic consistency and reducing the growth of mold and bacteria. By giving aesthetic functions to the fan front cover 200, the independent decorative cover plate in traditional solutions is completely eliminated, achieving structural integration and cost optimization. This solution directly reduces the number of parts in the air-cooled module, simplifies material management and supply chain processes, and lowers mold development and parts procurement costs. At the same time, the assembly process is also streamlined, improving production efficiency and achieving cost reduction and efficiency improvement from the manufacturing end. Secondly, the integrated design eliminates the redundant thickness occupied by the original decorative parts, which reduces the total thickness of the air-cooled module in the direction perpendicular to the wall of the inner liner 11 of the car refrigerator 10. This allows for the use of a thicker foam insulation layer with the same thickness, which helps to better maintain the heat insulation performance of the refrigerator, reduce cold loss, thereby reducing the workload of the compressor and achieving the purpose of energy saving and stable temperature control.

[0030] In this embodiment, the fan front cover 200 and the mounting base 100 are detachably connected. To achieve convenient disassembly and assembly as well as a secure connection, a snap-fit ​​structure is preferred. This snap-fit ​​structure requires no tools and allows for quick manual disassembly and assembly. The snap-fit ​​structure includes a snap-fit ​​210 on the fan front cover 200 and a snap-fit ​​interface 110 on the mounting base 100, such as... Figure 6 , Figure 7As shown, the card interface 110 is used to fix the buckle 210. The buckle 210 is made of elastic plastic material and has a certain deformation capability. The end of the buckle 210 is provided with a barb structure. The card interface 110 adopts a through hole structure that is adapted to the shape of the buckle 210. The inner wall of the through hole is provided with a slot that cooperates with the barb. When the fan front cover 200 is connected to the mounting base 100, the buckle 210 is squeezed and undergoes elastic deformation. After being inserted into the card interface 110, the barb engages with the slot to fix the two. When disassembling, the fan front cover 200 can be separated from the mounting base 100 by pulling it out. In addition to the above structure, the snap-fit ​​structure can also adopt a snap-fit ​​interface 110 set on the fan front cover 200 and a snap-fit ​​210 set on the mounting base 100. The snap-fit ​​interface 110 is used to fix the snap-fit ​​210. Its working principle is the same as the above structure, only the setting positions of the snap-fit ​​210 and the snap-fit ​​interface 110 are interchanged. In addition, the detachable connection between the fan front cover 200 and the mounting base 100 can also adopt magnetic connection, plug-in connection and other forms. Magnetic connection can further improve the convenience of disassembly and assembly, while plug-in connection can improve the sealing performance after the two are connected and reduce airflow leakage.

[0031] In this embodiment, the fan body 300 is installed between the mounting base 100 and the fan front cover 200, and is detachably connected to the fan front cover 200. The fan body 300, as the core power component of the air-cooling module, drives airflow to achieve mixed-flow cooling. The fan body 300 includes an impeller 310 and a mounting shell 320. The mounting shell 320 is manufactured using injection molding, and has an internal mounting cavity for accommodating the impeller 310. The impeller 310 is fixedly installed in this mounting cavity. The mounting shell 320 protects the impeller 310 and fixes its position. To achieve a detachable connection between the fan body 300 and the fan front cover 200, the mounting shell 320 is provided with a light hole 322, and the fan front cover 200 is provided with a corresponding threaded hole 280. Figure 5 As shown, a hand-tightened screw is used to connect the fan body 300 through the light hole 322 and the threaded hole 280, thus securing the two. This threaded connection method is convenient for disassembly and assembly, and also ensures the stability of the fan body 300 after installation, preventing the fan body 300 from loosening due to vehicle bumps. In addition to the above threaded connection method, the detachable connection between the fan body 300 and the fan front cover 200 can also be achieved by a snap-fit ​​connection, that is, an elastic snap is set on the edge of the mounting shell 320, and a snap-fit ​​groove is set at the corresponding position on the fan front cover 200, and the fixation is achieved by the engagement of the elastic snap and the snap-fit ​​groove; it can also be achieved by a plug-in connection, with a pin set on the mounting shell 320 and a slot set at the corresponding position on the fan front cover 200, and the pin is inserted into the slot for positioning and fixation, and the connection stability can be improved by setting an elastic protrusion and the interference fit between the positioning groove; it can also be achieved by a magnetic connection, with a permanent magnet attached to the mating surface of the fan body 300 and the fan front cover 200, which allows for quick disassembly and assembly without damaging the surface of the components.

[0032] When the vehicle refrigerator 10 needs enhanced cooling performance, the air-cooled module 20 is plugged into the inner liner 11 of the vehicle refrigerator 10, such as... Figure 8 As shown, the airflow generated by the air-cooling module 20 provides mixed-flow cooling for the inner liner 11 of the refrigerator. The plug-and-play installation is based on the compatible design of the mounting base 100 and the mounting slot 101 of the inner liner 11 of the vehicle refrigerator 10. The mounting base 100 adopts a structure that fits the mounting slot 101, and the cooperation between the positioning block 120 and the positioning port 270 achieves precise positioning. It can be quickly inserted into the mounting slot 101 without adjusting the angle, completing the installation of the air-cooling module 20. The entire installation process is short and convenient, easily completed by ordinary users. When the cooling demand of the vehicle refrigerator 10 is low or no additional cooling effect is required, the air-cooling module 20 can be directly pulled out of the mounting slot 101 for quick disassembly, flexibly adapting to different usage scenarios. To improve the convenience and stability of plug-and-play installation, a guide ramp can be provided on the outer wall of the mounting base 100, and a corresponding guide chamfer can be provided at the entrance of the mounting groove 101. Through the cooperation of the guide ramp and the guide chamfer, the mounting base 100 is guided to quickly insert into the mounting groove 101. At the same time, an elastic sealing gasket can be provided on the mating surface between the mounting base 100 and the mounting groove 101, which not only ensures the sealing after installation and reduces the leakage of cold air inside the box, but also plays a buffering role and reduces the impact of vehicle bumps on the mounting base 100.

[0033] It should be noted that when switching the cooling effect, the air-cooling module 20 can be disassembled and installed as a whole, or only the fan front cover 200 and the fan body 300 can be removed. Since the fan body 300 is installed on the fan front cover 200, only the fan front cover 200 needs to be removed and installed during disassembly and assembly.

[0034] Considering that the air-cooled module 20 requires a stable power supply during operation, and that the detachable connection structure may cause poor power supply contact, the fan front cover 200 is provided with a first electrical contact 220, and the inner side wall of the mounting base 100 is provided with a second electrical contact 130. When the first electrical contact 220 and the second electrical contact 130 are electrically connected, the vehicle refrigerator 10 supplies power to the air-cooled module 20. The first electrical contact 220 adopts an elastic conductive sheet structure and is electrically connected to the motor of the fan body 300. The second electrical contact 130 adopts a fixed conductive sheet structure and is fixedly installed on the corresponding position of the inner side wall of the mounting base 100. It is electrically connected to the power supply circuit of the vehicle refrigerator 10. When the fan front cover 200 is in place with the mounting base 100, the first electrical contact 220 and the second electrical contact 130 are in close contact to achieve electrical conduction. The electrical energy of the vehicle refrigerator 10 is transmitted to the fan body 300 through the second electrical contact 130 and the first electrical contact 220 to drive the impeller 310 to rotate. When the fan front cover 200 is separated from the mounting base 100, the first electrical contact 220 and the second electrical contact 130 are disconnected, and the power supply stops, which ensures safety and avoids unnecessary power consumption.

[0035] In addition to the aforementioned structure of elastic conductive sheet and fixed conductive sheet, the first electrical contact 220 and the second electrical contact 130 can also adopt a structure of pin-type contact and hole-type contact. The pin-type contact is set on the fan front cover 200, and the hole-type contact is set on the mounting base 100. When mating, the pin-type contact is inserted into the hole-type contact to achieve electrical conduction. This structure provides a tighter contact and stronger power supply stability. Furthermore, an anti-oxidation metal layer, such as gold or silver plating, can be plated on the surface of the electrical contacts to prevent oxidation and rust after long-term use, ensuring power supply stability and extending service life. A waterproof sealing sleeve can also be installed around the electrical contacts to prevent condensate from dripping from the inner liner 11 of the vehicle refrigerator 10 onto the electrical contacts, causing a short circuit. It should be noted that the electrical connection between the mounting base 100 and the vehicle refrigerator 10 can be a plug-in connection, such as a power plug on the mounting base 100 and a corresponding power socket on the vehicle refrigerator 10.

[0036] To facilitate users' intuitive understanding of the fan body 300's operating status and prevent situations where the impeller 310 malfunctions without the user's notice, a power indicator light 230 is provided on the outer side of the fan front cover 200. The power indicator light 230 indicates the operating status of the fan body 300. The power indicator light 230 is electrically connected to the first electrical contact 220. When the first electrical contact 220 and the second electrical contact 130 are connected and the fan body 300 is operating normally, the power indicator light 230 illuminates with a clear and intuitive green light. When the fan body 300 malfunctions and cannot operate normally, or when the power supply is interrupted, the power indicator light 230 turns off. If the fan body 300 experiences abnormal conditions such as jamming or overload, the power indicator light 230 can switch to a red light to remind the user to check and maintain it promptly. In addition to the above color indication method, the power indicator light 230 can also use flashing frequency to distinguish the operating status, such as slow flashing during normal operation and rapid flashing during abnormal operation.

[0037] To ensure smooth airflow and improve the mixed-flow cooling effect, the fan front cover 200 and the fan mounting shell 320 enclose a first space 201, within which the impeller 310 is located. The fan front cover 200 and the mounting base 100 enclose a second space 202, which is located below the first space 201. The first space 201 serves as the initial airflow receiving chamber, collecting the airflow drawn in by the fan body 300. The second space 202 serves as the airflow guiding and transition chamber, guiding the airflow to the air outlet 250. This rational layout of the two spaces enables orderly airflow, reduces airflow resistance, and improves cooling efficiency. The fan front cover 200 is provided with an air inlet 240 and an air outlet 250, and the mounting shell 320 is provided with an adapter 321 located below the first space 201. Driven by the impeller 310, air is drawn into the first space 201 through the air inlet 240, and then sequentially discharged through the adapter 321, the second space 202, and the air outlet 250, forming a complete airflow cycle to achieve mixed-flow cooling of the inner liner 11 of the vehicle refrigerator 10. Figure 4 As shown. The air inlet 240 is located above the air outlet 250. Both can adopt a grille structure to ensure smooth air intake and prevent foreign objects from entering the air-cooled module 20 and damaging the fan body 300. In addition to the grille structure, the air inlet 240 and the air outlet 250 can also adopt a perforated plate structure with the diameter of the holes set to 1-3mm, which can achieve effective air intake and play a certain role in dust prevention. Removable dust filters can also be installed on the inside of the air inlet 240 and the air outlet 250. The filters can be removed and cleaned regularly to prevent dust from entering the fan body 300 and affecting the cooling effect and equipment life.

[0038] To further optimize airflow guidance and improve the mixed-flow cooling effect, a guide vane 260 is provided on the side of the fan front cover 200 near the fan body 300. The guide vane 260 has a U-shaped structure, with its upper opening connecting to the first space 201. The area enclosed by the guide vane 260 corresponds to the second space 202. The guide vane 260 is manufactured using an integral injection molding process with the fan front cover 200, resulting in a stable overall structure that requires no additional fixing. The U-shaped guide vane 260 can gather and guide the airflow within the first space 201, generating a vortex effect to prevent airflow dispersion and thus better guide the airflow to the air outlet 250.

[0039] Considering that if the airflow discharged from the air outlet 250 were directly directed towards the air inlet 240, it would cause airflow recirculation, affecting air intake efficiency and cooling effect, and would also prevent complete airflow circulation within the inner liner 11, an oblique hole is provided on the wall of the fan front cover 200 corresponding to the second space 202. This oblique hole serves as the air outlet 250, located below the air inlet 240, to guide the discharged airflow diagonally downwards away from the air inlet 240. The angle of the oblique hole is set between 30° and 60°. Within this angle range, airflow recirculation can be effectively avoided, while also guiding the airflow towards the bottom of the inner liner 11 of the car refrigerator 10. After reaching the bottom, the airflow naturally rises, forming a complete circulating airflow, achieving forced heat exchange and cooling of the cabinet. This allows for a larger airflow area, covering a larger area of ​​the evaporator, improving cooling uniformity and efficiency.

[0040] This embodiment also provides a vehicle-mounted refrigerator 10, which includes the aforementioned integrated mixed-flow air-cooling module 20. The inner liner 11 of the vehicle-mounted refrigerator 10 has a mounting groove 101 on its side wall, and a mounting base 100 is inserted into the mounting groove 101. Optionally, a temperature sensor is installed inside the vehicle-mounted refrigerator 10. The temperature sensor is linked to the air-cooling module 20. When the temperature inside the inner liner 11 is higher than a set value, the air-cooling module 20 automatically starts; when the temperature is lower than the set value, the air-cooling module 20 automatically stops, achieving intelligent control. The air-cooling module 20 can be used in both direct-cooling and air-cooling refrigerators. Through its air-cooling module 20's method of first drawing in air and then blowing it out, it achieves rapid cooling and uniform temperature distribution.

[0041] This embodiment also provides a vehicle including the aforementioned vehicle-mounted refrigerator 10. The vehicle-mounted refrigerator 10 can be installed in the armrest box, trunk, or between the rear seats, adapting to the installation needs of different vehicle models. The vehicle-mounted refrigerator 10 is powered by the vehicle's onboard power supply and also has a backup battery. When the vehicle is turned off, the backup battery continues to power the vehicle-mounted refrigerator 10 and the air-cooling module 20, ensuring the refrigeration effect of the food inside the inner liner 11. In addition to the above installation method, the vehicle-mounted refrigerator 10 can also adopt a movable installation structure, with casters and a positioning lock at the bottom, allowing users to adjust the position of the vehicle-mounted refrigerator 10 as needed. The positioning lock can fix the vehicle-mounted refrigerator 10, preventing it from sliding during vehicle operation.

[0042] In addition, a control interface for the vehicle refrigerator 10 can be set on the vehicle's central control screen. Users can intuitively view the temperature of the vehicle refrigerator 10 and the working status of the air-cooled module 20 through the central control screen. At the same time, they can remotely control the start, stop and speed adjustment of the air-cooled module 20, improving ease of use. The vehicle can also be equipped with a vibration monitoring module. When the vehicle experiences severe bumps, the air-cooled module 20 will temporarily reduce its speed to reduce vibration damage to the air-cooled module 20 and extend its service life.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
