When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] With economic development, people have increasingly higher demands for quality of life. For example, during long-distance travel or outdoor activities, there is a need for cold drinks, food preservation, and storage of special medicines; and there is a need for instant cool drinks to relieve driving fatigue in the hot summer. Therefore, car refrigerators have become one of the travel companions that enhance the travel experience in modern outdoor life.

[0039] A car refrigerator is a type of refrigerator, also known as a freezer or refrigerated box. It is a refrigeration device used to maintain a constant low temperature. It is also a consumer product that keeps food or other items at a constant low temperature. It uses a compressor and an ice maker to freeze the space inside the freezer or refrigerator, thereby achieving the function of food preservation and freezing.

[0040] Vehicle refrigerators generally include compressor-type refrigerators, thermoelectric (semiconductor refrigeration) refrigerators, or hybrid compressor-thermoelectric refrigerators. Compressor-type refrigerators include direct-cooling refrigerators and air-cooling refrigerators. This invention mainly focuses on air-cooling refrigerators, or composite refrigerators with air-cooling systems. The following description uses an air-cooling vehicle refrigerator as an example. This refrigerator includes a refrigerator body and an evaporator fan. The refrigerator body generally includes the cabinet and the refrigeration system, which are the necessary components of a refrigerator.

[0041] The working principle of an air-cooled car refrigerator is that the compressor performs work on the refrigeration system, utilizing the thermodynamic cycle of the refrigerant to achieve cooling. Specifically, the refrigerant vaporizes in the evaporator inside the refrigerator, absorbing heat from the interior and lowering the temperature. Then, the refrigerant is drawn into the compressor, compressed into high-pressure, high-temperature vapor, and discharged into the condenser. In the condenser, the refrigerant releases heat to the environment and condenses into a high-pressure liquid. Finally, the high-pressure liquid is depressurized by a throttling mechanism and re-enters the evaporator to begin a new cycle. An evaporator fan is also installed on the evaporator side, forcibly circulating the cold air generated by the evaporator to all corners of the refrigerator, thus ensuring even distribution of cold air and improving the refrigerator's cooling efficiency.

[0042] For pre-installed car refrigerators, which are installed in the center console of a car, space is very limited. Common air-cooling solutions use axial fans for air circulation to lower the internal temperature. The axial fan's outlet is usually located on the inner wall of the storage compartment. Because the outlet cannot be obstructed, and because axial fans have a certain size and a large outlet area, the outlet occupies too much space on the inner wall of the storage compartment. This results in insufficient height for the storage drawers. When users place a lot of food in the drawers, the lack of space above them causes items to fall out when the drawers are pulled out, affecting the user experience.

[0043] This invention proposes a refrigerator designed to increase the height of the refrigerator's storage drawers. This refrigerator is typically mounted in a vehicle and is usually referred to as a vehicle refrigerator. Of course, the refrigerator can also be used independently, for example, as an outdoor refrigerator or a mini portable refrigerator. The following description will focus on the refrigerator's typical use in a vehicle.

[0044] The following description uses a wind-cooled car refrigerator as an example. For ease of understanding and explanation, please refer to the appendix to this specification. Figures 1 to 5 In the diagram, the solid arrow indicates a cavity, opening, or surface.

[0045] Please see Figures 1 to 5In one embodiment of the present invention, the refrigerator 10 includes a refrigerator body 11, a storage drawer 400, and a fan assembly 300. The refrigerator body 11 has a mounting cavity 102, a receiving cavity 101, and a first opening 103 communicating with the receiving cavity 101. The mounting cavity 102, the receiving cavity 101, and the first opening 103 are arranged side by side along a first direction of the refrigerator body 11. The storage drawer 400 is slidably disposed in the receiving cavity 101 from the first opening 103 and along the first direction. The fan assembly 300 is disposed in the mounting cavity 102 and has an air outlet 301. The storage drawer 400 has a bottom 401 and an opening 402. The accommodating cavity 101 has a first sidewall 104 facing the opening 402, and the air outlet 301 is located between the opening 402 end of the storage drawer 400 and the first sidewall 104; the fan assembly 300 includes an evaporating fan 310, the air outlet side of the evaporating fan 310 is connected to the air outlet 301, and the air outlet 301 is connected to the accommodating cavity 101; the distance from the opening 402 end of the storage drawer 400 to the first sidewall 104 is a first distance h1, and the distance from the end of the evaporating fan 310 away from the first sidewall 104 to the first sidewall 104 is a second distance h2, and the first distance h1 is not greater than the second distance h2.

[0046] The refrigerator body 11 refers to the key parts that constitute the physical form of the refrigerator 10 and realize its cooling, heat preservation and storage functions. The refrigerator body 11 generally includes the cabinet 100 and the refrigeration system 200, etc., which are necessary components that constitute the refrigerator 10.

[0047] The cabinet 100 is the main frame of the refrigerator 10. It also typically serves as the mounting carrier for other components of the refrigerator 10. Generally, the cabinet 100 is used for installation and fixation to the vehicle body. Additionally, the cabinet 100 forms a storage cavity for storing food or other items. The cabinet 100 can be integrally molded, with a foamed space constructed within it. Alternatively, the cabinet 100 can typically include an outer shell 110 and an inner shell 120, with a foamed space formed between the outer shell 110 and the inner shell 120, which is filled with foam material.

[0048] The first opening 103 is generally understood as an opening for taking out or putting in items. The first opening 103 is characterized as being located in the outer shell 110, but is actually located in both the inner shell 120 and the outer shell 110. The inner shell 120 is usually configured to form a receiving cavity 101, which is a space for storing items. The receiving cavity 101 is used to place the storage drawer 400. The first opening 103 allows the storage drawer 400 to enter and exit. The storage drawer 400 is designed to be pull-out, so that the drawer can be pulled in and out at the first opening 103 and move along the first direction, facilitating the storage and retrieval of items.

[0049] The storage drawer 400 has a bottom 401 and an opening 402. The bottom 401 of the storage drawer 400 serves as a support structure, enabling the storage drawer 400 to stably support items. The opening 402 is an open port, which facilitates the pulling out of the drawer and the placement of items, and forms an air flow channel with the fan outlet to optimize air circulation.

[0050] For example, the storage drawer 400 generally includes a drawer box 410 and a drawer panel 420. The storage drawer 400 is slidably disposed in the receiving cavity 101 from the first opening 103 and along the first direction. It can be understood that the storage drawer 400 is movably disposed in the receiving cavity 101 in a first position and a second position. In the first position, the drawer panel 420 covers the first opening 103, and a storage cavity is formed between the drawer box 410 and the refrigerator body 11. The temperature of the storage cavity can be adjusted. In the second position, the drawer panel 420 opens the first opening 103, and the user can take out the items from the storage box or put the items into the storage box.

[0051] The refrigeration system 200 is responsible for regulating the temperature inside the storage cavity to maintain it at a suitable low temperature, thereby achieving the purpose of refrigeration or freezing. Please refer to [link / reference]. Figure 5 The refrigeration system 200 typically includes a compressor 210, a condenser 220, and an evaporator 230, wherein the compressor 210, the condenser 220, and the evaporator 230 are interconnected to form a refrigerant circulation heat exchange loop.

[0052] In this embodiment, the inner shell 120 also forms a mounting cavity 102, which is typically used to house the fan assembly 300. The fan assembly 300 is used for the circulation and distribution of cold air, improving the uniformity of the internal temperature of the refrigerator 10. Through the air outlet of the fan assembly, the cold airflow can be guided to the storage drawer 400 area, effectively improving the cooling effect.

[0053] The fan assembly 300 includes an evaporator fan 310, which is typically a centrifugal fan. The fan assembly 300 is provided with an air outlet 301. The air outlet side of the evaporator fan 310 is connected to the air outlet 301, and the air outlet 301 is connected to the accommodating cavity 101. The first opening 103 may be formed by the fan housing 311 of the evaporator fan 310. Of course, the air outlet 301 may also be formed by other components, such as a duct partition 320 or a duct guide.

[0054] Air outlet 301 is connected to the accommodating cavity 101. For the accommodating cavity 101, air outlet 301 is actually the cold air inlet of the accommodating cavity 101. After passing through the evaporator fan 310, the cold air comes out through the air outlet and enters the accommodating cavity 101, that is, enters the drawer box 410.

[0055] The accommodating cavity 101 has a first sidewall 104 facing the opening 402. This first sidewall 104 is directed against the inner wall surface constituting the accommodating cavity 101, that is, one side wall of the accommodating cavity 101. The first sidewall 104 is typically the top wall or side wall of the accommodating cavity 101. For example, when the refrigerator 10 is placed in such a position... Figure 2 As shown, the first sidewall 104 can be understood as the top wall of the refrigerator 10. When the refrigerator 10 is placed in the following position... Figure 6 As shown, the first sidewall 104, which is the refrigerator body 11, has a sidewall facing the opening 402.

[0056] Furthermore, in order to increase the height of the storage drawer 400, the air outlet 301 is located between the open end 402 of the storage drawer 400 and the first side wall 104. The distance from the open end 402 of the storage drawer 400 to the first side wall 104 is a first distance h1, and the distance from the end of the evaporator fan 310 away from the first side wall 104 to the first side wall 104 is a second distance h2. The first distance h1 is not greater than the second distance h2.

[0057] The distance from the open end 402 of the storage drawer 400 to the first side wall 104 is the first distance h1. Please refer to [link to relevant documentation] for the first distance h1. Figure 2 h1, the distance from the end of the evaporator fan 310 away from the first sidewall 104 to the first sidewall 104 is the second distance h2, which can be found in [reference needed]. Figure 2 h2, with Figure 2 For example, the opening 402 end face of the storage drawer 400 is higher than the lower end face of the fan assembly 300. In other words, the drawer box 410 part of the storage drawer 400 overlaps with the projection of the evaporator fan 310 along the first direction, so that the fan assembly 300 and the drawer area share a part of the space, thereby reducing the area of ​​the inner wall surface of the storage drawer 400 occupied by the air outlet 301, and thus freeing up more space for the height of the storage drawer 400.

[0058] The technical solution of the present invention places the air outlet of the fan assembly 300 between the open end 402 of the storage drawer 400 and the first side wall 104, and makes the open end face 402 of the storage drawer 400 higher than the lower end face of the fan assembly 300, thereby reducing the area occupied by the air outlet of the fan on the inner wall of the accommodating cavity 101. In this way, more height space is provided for the storage drawer 400. Compared with the traditional solution using an axial flow fan, the technical solution of the present invention can increase the height of the storage drawer 400 in the accommodating cavity 101, thereby reducing the problem of items falling when the storage drawer 400 is pulled out.

[0059] In one embodiment, please refer to Figure 2The evaporator fan 310 is a centrifugal fan, and the evaporator fan 310 includes an impeller 312. The rotation center line of the impeller 312 is defined as the axis of the impeller 312. The axis of the impeller 312 extends along the first direction.

[0060] The impeller 312's axis extends along the first direction, which can be understood as the impeller 312's axis being parallel to the first direction, or the impeller 312's axis having a certain angle, but this angle is very small, and the impeller 312's axis and the first direction extending in the same direction have similar orientation trends.

[0061] The impeller 312 axis refers to the center line of rotation of the impeller 312. Normally, the impeller 312 rotates around the axis to drive airflow. In this embodiment, the impeller 312 axis extends along the first direction of the refrigerator body 11, that is, the positional relationship between the fan and the storage drawer 400 is arranged along the same axis. By setting the impeller 312 axis along the first direction, the centrifugal fan in this embodiment also has the layout of an axial fan. In this way, the layout of the fan assembly 300 can be more compact, reducing the space occupied by the fan assembly 300 and freeing up more space for the height design of the storage drawer 400.

[0062] In this embodiment, the impeller 312 axis extends along the first direction, making the spatial layout of the evaporator fan 310 and the storage drawer 400 more compact, thereby effectively saving space. In the vehicle refrigerator 10, since space is relatively limited, this design can make the most of the available space, so that the evaporator fan 310 can work normally without wasting any extra space.

[0063] Since the air outlet 301 is located on the side of the storage drawer 400, the height of the storage drawer 400 cannot be too high. Furthermore, the distance between the axis of the impeller 312 and the first side wall 104 is a third distance h3, and the first distance h1 is not less than the third distance h3. In this way, a windproof gap 105 is formed between the lower edge of the air outlet 301 and the open end 402 of the storage drawer 400. This ensures that the space between the open end 402 of the storage drawer 400 and the first side wall 104 is not too narrow, thus maintaining a good airflow channel. While increasing the height of the storage drawer 400, the impact on the air volume and cooling effect of the evaporator fan 310 is reduced, which can further improve the user experience.

[0064] In one exemplary embodiment, please refer to Figure 2 The refrigerator body 11 includes a cabinet 100, which forms the mounting cavity 102, the receiving cavity 101 and the first opening 103. The first side wall 104 is the top wall of the mounting cavity 102 and the receiving cavity 101.

[0065] In one embodiment, the fan assembly 300 includes a duct partition 320 disposed within the housing 100, the duct partition 320 separating the mounting cavity 102 and the receiving cavity 101, the duct partition 320 having the air outlet 301, and the evaporator fan 310 disposed within the duct partition 320.

[0066] The main function of the air duct partition 320 is to divide the internal space of the cabinet 100 into two different areas, such as the mounting cavity 102 and the accommodating cavity 101. The mounting cavity 102 is typically used to install and accommodate equipment such as the evaporator fan 310 and the evaporator 230, while the accommodating cavity 101 is used to store food or other items. By separating the two areas through the air duct partition 320, the direct impact of the airflow generated by the evaporator fan 310 on the return airflow to the air inlet side can be reduced, thereby reducing the operating efficiency of the refrigerator 10. At the same time, the air duct partition 320 also helps with physical isolation and effectively guides airflow.

[0067] The air duct partition 320 is provided with the air outlet 301, that is, the air outlet 301 is opened on the air duct partition 320. At this time, the air duct partition 320 is not only a physical barrier, but also plays the role of guiding airflow. The air flows through the design route of the air duct partition 320, which can make the cooling air evenly distributed in the accommodating cavity 101.

[0068] The evaporator fan 310 is located on the air duct partition 320. The evaporator fan 310 is installed on the air duct partition 320. Since this embodiment is a centrifugal fan, the distance from the air outlet side of the evaporator fan 310 to the air outlet 301 can be shortened, which can not only improve the airflow guidance efficiency, but also save space.

[0069] In one embodiment, the air duct baffle 320 includes a baffle body 321 and an air outlet 322 disposed on the baffle body 321. The air outlet 322 extends from the baffle body 321 in the first direction, and the air outlet 301 is disposed on the side of the air outlet 322 away from the baffle body 321.

[0070] The function of the partition body 321 is to separate the air duct partition 320, and to separate the internal space of the housing 100 into the installation cavity 102 and the accommodating cavity 101, and to provide support and stability. The partition body 321 needs to have a certain rigidity and strength to ensure the stability of the overall structure and to maintain a good airflow channel inside the housing 100.

[0071] The air outlet 322 can be understood as a protruding part of the partition body 321, and is a structure that protrudes towards the receiving cavity 101. The extension of the air outlet 322 and the design of the air outlet directly affect the airflow distribution. The air outlet 322 extends from the partition body 321 in the first direction, and the air outlet 301 is located on the side of the air outlet 322 away from the partition body 321, which can guide the airflow out, so that the cold air coming out of the air outlet 301 can be blown further. The air outlet 322 and the partition body 321 can be set separately or as a whole. Preferably, the air outlet 322 is integrally formed with the air duct partition 320.

[0072] In this embodiment, the air outlet 322 extends from the partition body 321 in the first direction, and the air outlet 301 is located on the side of the air outlet 322 away from the partition body 321, so that the cold air coming out of the air outlet 301 blows further, and the airflow can be more evenly distributed to each part of the accommodating cavity 101, thereby improving the temperature uniformity of the accommodating cavity 101.

[0073] Furthermore, there are multiple air outlets 322, and the multiple air outlets 322 are located at one end of the partition body 321 near the first side wall 104. Thus, in this embodiment, the air volume of the fan assembly 300 can be increased while increasing the height of the storage drawer 400 in the accommodating cavity 101.

[0074] In one embodiment, the evaporator fan 310 includes a housing 311, which is disposed at one end of the partition body 321 near the first sidewall 104. The housing 311 and the partition body 321 enclose a fan cavity, and the impeller 312 is disposed in the fan cavity and mounted on the partition body 321.

[0075] The casing 311 is the external protective structure of the centrifugal fan. The casing 311 of the centrifugal fan typically includes a surrounding plate, a first side plate and a second side plate located on opposite sides of the surrounding plate. One of the first side plate and the second side plate is provided with an air inlet 302. For ease of description, the air inlet 302 is provided on the first side plate, and the air outlet of the centrifugal fan is located on the surrounding plate. The casing 311 and the partition body 321 enclose each other to form a fan cavity. That is, the second side plate and the partition body 321 are integrally formed. In this way, the number of components of the fan assembly 300 can be reduced, thereby reducing the internal space of the fan assembly 300. The casing 311 is located at the end of the partition body 321 near the first side wall 104, which can shorten the distance between the air outlet side of the impeller 312 and the air outlet 301.

[0076] In one embodiment, the evaporator fan 310 includes a housing 311, the impeller 312 is disposed inside the housing 311, and the air inlet 302 of the evaporator fan 310 is disposed on the side of the housing 311 away from the receiving cavity 101; the side of the housing 311 with the air inlet 302 is defined as the air inlet surface, and an air inlet gap is provided between the air inlet surface and the housing 100.

[0077] The air inlet side refers to the side of the housing 311, which has an air inlet 302. The air inlet 302 is located on the side of the housing 311 away from the receiving cavity 101, that is, away from the air outlet 301. There is an air inlet gap between the air inlet side and the housing 100 to allow the fan to enter. In this way, the cold air coming out of the air outlet 301 can first pass through the receiving cavity 101, and then go around to the air inlet side of the partition body 321 and the housing 311, and flow back to the air inlet 302, thereby reducing the direct flow of cold air from the air outlet 301 back to the air inlet 302.

[0078] If the air inlet spacing is too small, it may obstruct airflow, affecting the suction capacity and cooling effect of the evaporator fan 310. Furthermore, the length of the air inlet spacing is not less than half the diameter of the impeller 312. This air inlet spacing allows the airflow to enter the evaporator fan 310 more smoothly and evenly, reducing airflow disturbance or eddy phenomena, thereby improving the fan's air intake efficiency and overall cooling effect.

[0079] Furthermore, the lower end of the partition body 321 is provided with a return air vent 321a, and the storage drawer 400 is provided with an air passage vent 403 on the periphery of the accommodating cavity 101. The air passage vent 403, the return air vent 321a and the air inlet side of the evaporator fan 310 are connected to form a return air duct, and the evaporator 230 is disposed in the return air duct.

[0080] In one embodiment, the refrigerator body 11 includes an evaporator 230 located below the evaporator fan 310 and disposed within the return air duct.

[0081] Since the cold air is blown directly into the refrigerator 10 from the evaporator 230 through the fan, the evaporator 230 is located below the evaporator fan 310, which helps to improve the cooling speed. Secondly, during long-term use, the evaporator 230 may accumulate dust or frost, affecting the cooling effect. Placing it below the fan allows for the installation of a water collection box or similar device below the evaporator 230, facilitating defrosting and cleaning of the evaporator 230.

[0082] The present invention also proposes a vehicle, which includes a vehicle body and a refrigerator 10. The specific structure of the refrigerator 10 is as described in the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
