Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and more particularly to vehicle-mounted refrigerators. Background Technology

[0002] As a portable refrigeration device designed specifically for mobile travel scenarios, car refrigerators have been widely used in recent years with the popularization of lifestyles such as self-driving tours and outdoor camping, aiming to achieve efficient cooling and heat preservation functions within the limited space of a vehicle.

[0003] Existing products generally adopt a single-cavity layout in their structural design, meaning they have only one unified storage space for various beverages, fruits, and foods. Although some high-end models have optimized temperature control accuracy, energy consumption, and exterior materials, their fundamental storage structure remains unchanged. With the continuous improvement of automotive intelligence and humanization, the design of car refrigerators focuses more on leisure and lifestyle scenarios, neglecting a growing special need—the safe storage needs of patients with chronic diseases (such as diabetic patients) for medications, especially temperature-sensitive injectable solutions, during long-distance travel. This limitation in the original design makes it difficult for existing technologies to meet more complex and professional storage requirements.

[0004] Current mainstream car refrigerators have significant inherent flaws, primarily because their single storage space cannot allow for the categorization and storage of items with different properties. When users mix medications requiring constant temperature storage, such as insulin, with food and beverages, multiple risks arise: First, frequent opening and closing of the refrigerator door to access food causes drastic temperature fluctuations, resulting in continuous thermal shock. Many biological agents are extremely sensitive to temperature fluctuations, and repeated temperature changes can accelerate drug deterioration, directly endangering medication safety. Second, mixing items easily leads to cross-contamination; food juices may contaminate the surface of medicine bottles, increasing hygiene risks during medication use. Finally, in the bumpy environment of a moving vehicle, unsecured medicine bottles are prone to collisions with other hard objects, causing glass bottles to break or labels to wear off, resulting in unnecessary economic losses and affecting the continuity of treatment. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is to provide a vehicle refrigerator that can prevent temperature fluctuations and cross-contamination caused by mixing medicines and food in the vehicle; prevent collision damage and ensure the safety of medicine storage.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A vehicle-mounted refrigerator includes a refrigerator body, the upper side of which is hinged with a double-opening elbow door.

[0008] The refrigerator body has a main compartment and a refrigeration device inside. The refrigeration device includes a circulating fan for driving airflow in the main compartment. The air outlet of the refrigeration device is located in the main compartment. The main compartment is located below the elbow door. A protective hood is installed in the main compartment. The protective hood covers the outside of the air outlet of the refrigeration device. The protective hood has a main air duct and a secondary air duct.

[0009] The main storage compartment is equipped with an independent storage box. The independent storage box includes a sealed storage cavity for storing items and a storage air inlet and a storage air outlet communicating with the storage cavity. The independent storage box is detachably connected to the protective hood, and the storage air inlet is connected to the secondary air duct, and the storage air outlet is connected to the main storage compartment.

[0010] Preferably, the main air duct is arranged in a horizontal direction, and the secondary air duct is arranged perpendicular to the main air duct on at least one side thereof.

[0011] Preferably, there are two secondary air ducts, which are vertically arranged on the upper and lower sides of the main air duct.

[0012] Preferably, the independent storage box includes a storage box body and a storage cover. The storage box body is provided with a storage air inlet duct that communicates with its interior. The storage air inlet is opened on the storage air inlet duct and is connected to the secondary air duct. The storage air outlet is opened at the bottom of the storage box body.

[0013] Preferably, at least one horizontally arranged baffle is installed inside the storage box, and the baffle has several ventilation holes.

[0014] Preferably, the inner wall of the storage box is provided with a plurality of supporting protrusions, the plurality of supporting protrusions are in the same plane, and the baffle is disposed on the supporting protrusions.

[0015] Preferably, there are two baffles, and the two baffles are arranged vertically.

[0016] Preferably, the storage cover is magnetically connected to the upper side of the storage box, and the top of the storage cover is recessed with a pull groove.

[0017] Preferably, a control unit is provided inside the refrigerator body, a temperature and humidity sensor is provided in the main compartment, the temperature and humidity sensor is electrically connected to the control unit, and the control unit is electrically connected to the refrigeration device.

[0018] Preferably, a battery pack is installed inside the refrigerator body, and the battery pack is electrically connected to the control unit.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are:

[0020] The vehicle refrigerator of this application includes a refrigerator body, and the upper side of the refrigerator body is hinged with a double-opening elbow rest door; by setting the elbow rest door on the refrigerator body, the operation requirements of opening and closing can be met, and when the vehicle refrigerator of this application is set in the armrest box, it can replace the function of the armrest box, and the elbow can be rested on the application, saving effort.

[0021] The refrigerator body has a main storage compartment and a refrigeration unit inside. The refrigeration unit includes a circulating fan for driving airflow within the main storage compartment. The air outlet of the refrigeration unit is located inside the main storage compartment, which is correspondingly located below the elbow door. A protective hood is installed inside the main storage compartment, covering the outside of the air outlet of the refrigeration unit. The protective hood has a main air duct and a secondary air duct. An independent storage box is installed inside the main storage compartment. The independent storage box includes a sealed storage cavity for storing items and a storage air inlet and a storage air outlet communicating with the storage cavity. The independent storage box is detachably connected to the protective hood, and the storage air inlet is connected to the secondary air duct, while the storage air outlet is connected to the main storage compartment.

[0022] The vehicle-mounted refrigerator achieves functional zoning and independent temperature control of the storage space by incorporating independent storage boxes within the main internal compartment that connect to the secondary air duct of the protective hood. Each independent storage box forms a sealed cavity and directly connects to the outlet of the protective air duct via its dedicated air inlet, creating a cooling circulation path independent of the main compartment. This structure significantly reduces the interference of hot air introduced by frequent opening and closing of the main compartment door on the temperature of the medicine compartment, strictly controlling internal temperature fluctuations. This provides consistently suitable storage conditions for temperature-sensitive medications such as insulin, ensuring stable efficacy and safe use of the medications in a mobile vehicle environment.

[0023] The independent storage box features a detachable connection to the protective hood, allowing users to remove it entirely as needed for easy access to medications and subsequent cleaning and maintenance of the box's interior, preventing contamination residue. The sealed internal structure physically isolates food and medication bottles, preventing cross-contamination caused by liquid leakage or odor mixing. Simultaneously, with the bottles secured inside the independent box, they are protected from collisions with other items during vehicle movement, preventing bottle breakage or label damage, significantly improving the safety and reliability of medication management. This modular integrated design achieves refined differentiation of storage functions without increasing equipment size or occupying additional vehicle space.

[0024] As cold air flows through the protective hood, it is rationally diverted to the main and secondary air ducts, respectively cooling the main storage compartment and individual storage boxes. The cold air from the secondary duct enters the storage boxes directly through the connected air inlets, and after heat exchange, the warmed air returns to the main compartment through the bottom air outlet, participating in the main compartment's circulation process. This process reduces cold air loss and ineffective circulation, lowering the energy consumption required for temperature control. This application meets the diverse storage needs of various items without significantly increasing the complexity of the refrigeration device, improving the product's overall energy efficiency and economy.

[0040] To make the objectives, technical solutions, and advantages 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.

[0041] like Figures 1 to 6 As shown, this utility model includes a refrigerator body 1, and a double-opening elbow rest door 2 is hinged to the upper side of the refrigerator body 1. By setting the double-opening elbow rest door 2 on the upper side of the refrigerator body 1, it is not only convenient for users to open and close the refrigerator, but also enables the vehicle refrigerator to be effectively integrated into the vehicle armrest box. While realizing the refrigeration function, it replaces the elbow support function of the original armrest box, providing users with a comfortable pillow and backrest experience and achieving the effect of saving effort.

[0042] The refrigerator body 1 has a main compartment 11 and a refrigeration unit 3 inside. The refrigeration unit 3 includes a circulating fan 31 for driving airflow within the main compartment 11. The refrigeration unit 3 is an air-cooled refrigeration unit, which can cool the outside air and send it into the main compartment 11. Alternatively, the refrigeration unit 3 is a semiconductor refrigeration unit. When a semiconductor refrigeration unit is used, the air in the main compartment 11, after being driven by the circulating fan and cooled by the cooling plates, continues to circulate, thus cooling the main compartment 11. The refrigeration unit 3 is a well-known technology in this field, and its refrigeration principle and structure will not be described in detail here. The air inlet of the refrigeration unit 3 is connected to the outside, and the air outlet of the refrigeration unit 3 is located inside the main compartment 11, which is located below the elbow door 2. A protective air cover 4 is installed inside the main compartment 11, covering the outside of the air outlet of the refrigeration unit 3. The protective air cover 4 has a main air duct 41 and a secondary air duct 42.

[0043] An independent storage box 5 is installed inside the main storage compartment 11. The independent storage box 5 includes a sealed storage cavity for storing items and a storage air inlet 51 and a storage air outlet 52 that communicate with the storage cavity. The independent storage box 5 is detachably connected to the protective hood 4, and the storage air inlet 51 is connected to the secondary air duct 42, and the storage air outlet 52 is connected to the main storage compartment 11.

[0044] By connecting the air outlet of the refrigeration unit 3 to the main storage compartment 11 and covering it with a protective shroud 4, a reasonable distribution of airflow is achieved. The main air duct 41 and the secondary air duct 42 opened on the protective shroud 4 can guide the cold air to the storage space of the main storage compartment 11 and the independent storage box 5 respectively, forming two relatively independent cooling circulation paths. This design not only ensures the overall cooling effect of the main storage compartment 11, but also provides a dedicated temperature control environment for items that require special temperature protection.

[0045] The independent storage box 5 is detachably connected to the protective shroud 4, forming a modular design. When installed, its storage air inlet 51 precisely aligns with the secondary air duct 42, ensuring that cool air can directly enter the sealed storage cavity. After heat exchange, the airflow returns to the main storage compartment 11 through the storage air outlet 52 at the bottom, forming an independent circulation channel. This structure achieves dedicated temperature zone protection for temperature-sensitive items, maintains temperature balance with the main storage compartment 11, and facilitates user removal for cleaning and maintenance.

[0046] In this application, the main air duct 41 is arranged horizontally, and the secondary air duct 42 is arranged perpendicularly to the main air duct 41 on at least one side thereof; preferably, there are two secondary air ducts 42, which are arranged perpendicularly to the upper and lower sides of the main air duct 41. Correspondingly, there are also two storage air inlets 51, corresponding to the positions of the secondary air ducts 42.

[0047] The horizontal arrangement of the main air duct 41 enables uniform lateral delivery of cool air within the main storage compartment 11. The secondary air duct 42, positioned perpendicular to the main air duct 41, forms a diversion structure, guiding a portion of the cool air directionally to the independent storage box 5. The dual secondary air ducts 42, located on both the upper and lower sides, along with corresponding dual storage air inlets 51, achieve symmetrical airflow into the internal space of the independent storage box 5. This avoids uneven temperature distribution that might occur with unilateral airflow, significantly improving the temperature stability and cooling efficiency within the independent storage box 5, and optimizing the overall heat dissipation effect.

[0048] The independent storage box 5 includes a storage box body 53 and a storage cover 54. The storage box body 53 is provided with a storage air inlet duct 55 that communicates with its interior. A storage air inlet 51 is opened on the storage air inlet duct 55 and connects to the secondary air duct 42. A storage air outlet 52 is opened at the bottom of the storage box body 53. Correspondingly, there are two storage air inlets 55, which are arranged vertically.

[0049] By setting up independent storage air inlets 55, precise airflow guidance is achieved. Storage air inlets 55 connect with secondary air inlets 42, ensuring that cold air can directly enter the internal space of the storage box 53, avoiding loss of cold air during transport. The vertically arranged dual storage air inlets 55, combined with the storage air outlet 52 at the bottom, form a top-down, inside-out convection circulation, which facilitates the even distribution of cold air throughout the storage cavity, effectively preventing localized overheating. Simultaneously, the design of the bottom storage air outlet 52 prevents condensation buildup, improving the reliability of the equipment.

[0050] The storage cover 54 is magnetically connected to the upper side of the storage box 53, and the top of the storage cover 54 is recessed with a pull groove 541.

[0051] The storage box 53 has at least one horizontally arranged baffle 6 installed inside, and the baffle 6 has several ventilation holes 61. Additionally, the inner wall of the storage box 53 has several supporting protrusions 56, which are in the same plane, and the baffle 6 is disposed on the supporting protrusions 56. Preferably, there are two baffles 6, which are arranged vertically.

[0052] The magnetically attached storage lid 54 allows for convenient opening and closing, while the top slot 541 facilitates user operation. The storage box 53 features an internal baffle 6 with ventilation holes 61, creating multi-layered storage space while ensuring vertical airflow. The baffle 6 is supported by a support protrusion 56 for easy disassembly. The preferred double-layer baffle 6 design further optimizes space utilization, allowing temperature-sensitive items to be stored in layers while maintaining sufficient airflow circulation, ensuring uniform and stable cooling performance.

[0053] The refrigerator body 1 has a control unit inside, and a temperature and humidity sensor is installed in the main compartment 11. The temperature and humidity sensor is electrically connected to the control unit, and the control unit is electrically connected to the refrigeration unit 3. Preferably, the refrigerator body 1 has a battery pack 12 inside, and the battery pack 12 is electrically connected to the control unit.

[0054] The environmental parameters inside the main storage compartment 11 are monitored in real time by temperature and humidity sensors, and the data is fed back to the control unit. The control unit precisely regulates the refrigeration unit 3 according to a preset algorithm to ensure that the temperature inside the compartment is maintained within the set range. Preferably, the battery pack 12 provides an independent power supply to the system, enabling the system to continue operating even after the vehicle is turned off, effectively ensuring the storage safety of sensitive items such as medicines. This improves the automation level and reliability of the equipment, while also achieving optimized energy consumption management.

[0055] When in use, after the refrigeration device 3 is activated, the generated cold airflow is sent into the protective hood 4 from the air outlet. Within the protective hood 4, the airflow is divided into a main air duct 41 and a secondary air duct 42. The main air duct 41 delivers the cold air to the main storage compartment 11 for conventional refrigeration, while the secondary air duct 42 directs the cold air to the storage inlet duct 55 of the independent storage box 5. The cold air enters the sealed interior of the storage box 53 through the storage inlet 51, exchanges heat with the stored items, and then the heated airflow returns to the main storage compartment 11 from the bottom storage outlet 52, forming an independent circulating cooling path. This design ensures that the temperatures of the medicine area and the food area do not interfere with each other, effectively maintaining the stability of the medicine storage temperature.

[0056] The multi-layered baffles 6 and their ventilation holes 61 installed inside the independent storage box 5 via the supporting protrusions 56 promote vertical convection of cold air within the box, ensuring uniform temperature distribution. The magnetically connected storage lid 54 and pull groove 541 design ensure both airtightness and easy and quick access to items. The overall system achieves separate storage for medicines and food while ensuring high energy efficiency and ease of use.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
