[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] This application first proposes a car refrigerator, such as Figures 1 to 6 As shown, Figure 1 It is a structural schematic diagram of an embodiment of a vehicle refrigerator of the present application; Figure 2 yes Figure 1 A schematic side view of an embodiment; Figure 3 This is a schematic structural diagram of an embodiment of a door body and an axial flow fan of the present application; Figure 4 is a bottom view schematic diagram of an embodiment of the door body and the axial flow fan of the present application; Figure 5 This is a structural schematic diagram of an embodiment of the door body and the centrifugal fan of the present application; Figure 6 The vehicle refrigerator comprises a housing 11, a door 12, a fan 02, and a refrigeration assembly 03. The housing 11 forms a refrigeration cavity 04 and a first opening connected to the refrigeration cavity 04. The door 12 covers the first opening, and the fan 02 is arranged on a side of the door 12 close to the refrigeration cavity 04. The refrigeration assembly 03 is installed on the housing 11 to refrigerate the refrigeration cavity 04.

[0018] Specifically, the fan 02 works in the refrigeration chamber 04. The fan 02 can enhance the convection effect of the airflow in the refrigeration chamber 04. It does not need to be connected to the external airflow to enhance the convection of the airflow in the refrigeration chamber 04. The convection intensity can also be adjusted by adjusting the wind force of the fan 02.

[0019] In some embodiments, the fan 02 can work synchronously with the refrigeration component 03, or it can work asynchronously, and there is no specific limitation. Since the fan 02 can enhance the convection of the airflow in the refrigeration cavity 04, it is not necessary to set an air vent connected to the outside on the refrigeration cavity 04 to achieve a stronger convection effect of the airflow in the cavity. For example, during the production and assembly process, the fan 02 and the refrigeration component 03 can be assembled separately, the refrigeration component 03 can work independently to cool the refrigeration cavity 04, and the fan 02 can work independently to enhance the convection effect of the airflow in the refrigeration cavity 04. Therefore, the refrigeration method of the refrigeration component is not limited in the present application. For example, in an application scenario, Figure 1 As shown, the refrigeration assembly 03 includes a refrigeration component 31 (such as a compressor) and an evaporator (not shown). The refrigeration component 31 includes a compressor, a condenser, a condenser fan, etc. The evaporator is arranged outside the refrigeration cavity 04 and can cool the refrigeration cavity 04 by cooling the box body 11.

[0020] For another example, in other application scenarios (not shown), the refrigeration component may also be a refrigeration box disposed in the refrigeration cavity, etc., which is not specifically limited.

[0021] The beneficial effect of the above-mentioned arrangement is that the arrangement of the fan 02 facilitates to enhance the convection effect of the airflow in the refrigeration cavity 04, thereby improving the refrigeration uniformity and refrigeration speed in the refrigeration cavity 04, thereby improving the refrigeration effect; further, the fan 02 is arranged on the side of the door body 12 close to the refrigeration cavity 04, which is convenient for assembly and operation of the fan 02, and the fan 02 is arranged on the side of the door body 12 close to the refrigeration cavity 04 to facilitate to enhance the convection effect of the airflow in the refrigeration cavity 04; the refrigeration component 03 is installed on the box body 11, which facilitates to improve the position stability of the refrigeration component 03, thereby improving the reliability of the vehicle refrigerator.

[0022] Optionally, a groove that penetrates the refrigeration cavity 04 is formed on the inner wall of the door body 12, and the fan 02 is at least partially arranged in the installation cavity formed by the groove.

[0023] Optionally, the inner wall of the door body 12 forms a groove that passes through the refrigeration cavity 04. The fan 02 is arranged in the installation cavity formed by the groove, which can reduce the interference of the fan 02 on the usable space in the refrigeration cavity 04, and being arranged in the installation cavity formed by the groove facilitates improving the stability of the fan 02 and reducing the impact of external interference on the fan 02; further, the groove is formed by the inner wall of the door body 12, and the groove and the inner wall can be integrally formed, which can improve the stability of the groove.

[0024] Optionally, the fan 02 can be completely arranged in the installation cavity formed by the groove to further improve the anti-interference performance of the fan 02 and the aesthetics of the vehicle refrigerator.

[0025] Optionally, the fan 02 is spaced apart from the side wall 411 of the groove to form a first air duct 42 communicating with the refrigeration cavity 04 .

[0026] The first air duct 42 can improve the connectivity between the air inlet and / or air outlet of the fan 02 and the refrigeration chamber 04, thereby improving the convection enhancement effect of the fan 02 on the airflow in the refrigeration chamber 04; the fan 02 and the side wall 411 of the groove are spaced apart to form the first air duct 42 connected to the refrigeration chamber 04. This design has a simple structure, does not require complex production design, and can reduce the cost of production and assembly.

[0027] In another embodiment, the fan is at least partially spaced apart from the side wall of the groove, and a through hole communicating with the first air duct and the refrigeration chamber may be provided in the area not spaced apart.

[0028] Alternatively, if Figure 3 , Figure 4 As shown, the fan 02 includes an axial flow fan 21 , and the axial flow fan 21 is spaced apart from the bottom wall 412 of the groove to form a second air duct 43 connected to the air outlet of the axial flow fan 21 and to the first air duct 42 .

[0029] The impeller and blade design of the axial flow fan 21 can make the air flow out of the fan almost parallel to the rotation axis of the blade when it flows out of the fan through the fan outlet. The air inlet 211 and the air outlet 212 of the axial flow fan 21 are arranged in a straight line along the parallel line of the rotation axis of the blade. The axial flow fan 21 is easy to install. The setting of the second air duct 43 makes it easy for the air inlet 211 of the axial flow fan 21 to be connected with the first air duct 42 through the second air duct 43, and then can be connected with the refrigeration chamber 04, which is conducive to improving the blowing effect of the axial flow fan 21; and the setting of the first air duct 42 and the second air duct 43 makes it easy for the air flow to turn after passing through the first air duct 42, and then enter the second air duct 43, so as to facilitate the air flow to flow into the air inlet 211 of the axial flow fan 21; and the second air duct 43 can be formed by the spacing between the axial flow fan 21 and the bottom wall 412 of the groove, which has a simple structure and is easy to produce and install.

[0030] Optionally, the specific shape of the groove is not limited. For example, the inner wall of the groove can be set to be streamlined to improve the wind guiding effect of the air duct, reduce resistance, and thus save power consumption.

[0031] Optionally, the connection between the side wall 411 of the groove and the bottom wall 412 of the groove is arc-shaped or streamlined, which can improve the smoothness of the airflow when it turns from the first air duct 42 to the second air duct 43 and reduce resistance.

[0032] Optionally, the side wall 411 of the groove is arranged at an obtuse angle with the bottom wall 412 of the groove so that the inner diameter of the groove gradually increases from the bottom wall toward the refrigeration cavity 04, thereby facilitating the airflow to enter the axial flow fan 21 through the first air duct 42 and the second air duct 43.

[0033] Alternatively, if Figure 5 , Figure 6 As shown, the fan 02 includes a centrifugal fan 22 , and the side wall 411 of the groove is arranged at an obtuse angle with the bottom wall 412 of the groove, so that the inner diameter of the groove gradually increases in the direction from the bottom wall toward the refrigeration cavity 04 .

[0034] The centrifugal fan 22 is a fan that uses centrifugal force to transport airflow. Its working principle is to suck the airflow into the fan through the rotating impeller, then use the blades on the impeller to accelerate the airflow, and push the airflow to the air outlet through centrifugal force, so as to achieve the transportation and pressurization of the airflow. The wind pressure and air volume of the centrifugal fan 22 are greater, and a stronger convection effect can be achieved; and the air outlet 221 of the centrifugal fan 22 is perpendicular to the air inlet 222, and the side wall 411 of the groove is set at an obtuse angle to the bottom wall 412 of the groove, so that the inner diameter of the groove gradually increases from the bottom wall toward the refrigeration cavity 04, which is convenient for guiding and redirecting the airflow discharged from the air outlet 221 of the centrifugal fan 22, reducing the wind pressure loss in the process of the airflow flowing from the air outlet 221 to the outside of the installation cavity through the first air duct 42, thereby improving the convection effect.

[0035] Optionally, the degree of the angle between the side wall 411 of the groove and the bottom wall 412 of the groove can be designed according to needs, and angles of different degrees can achieve different diversion effects.

[0036] Optionally, the side wall 411 of the groove may also be a curved structure, which can guide the airflow discharged from the air outlet of the centrifugal fan 22 so as to flow out of the installation cavity formed by the groove.

[0037] Optionally, in some embodiments, since the air outlet 221 of the centrifugal fan 22 is perpendicular to the air inlet 222, no spacing is required between the centrifugal fan and the bottom wall 412 of the groove, so as to improve the integration of the vehicle refrigerator and improve the space utilization of the refrigeration cavity.

[0038] Optionally, the vehicle refrigerator further comprises a baffle movably connected to the fan 02 , and the baffle can be selectively at least partially covered at an opening of the first air duct 42 close to a side of the refrigeration chamber 04 .

[0039] Optionally, the baffle is movably connected to the fan 02, and can selectively at least partially cover the opening of the first air duct 42 on the side close to the refrigeration chamber 04, so as to facilitate the air intake or air outlet at the outlet by adjusting the baffle, thereby improving the convenience of adjusting the air volume of the fan 02 and improving the user experience.

[0040] Alternatively, if Figure 1 As shown, the vehicle refrigerator further includes a baffle 05 movably connected to the inner wall of the door body 12 , and the baffle can selectively at least partially cover the opening of the first air duct 42 on one side close to the refrigeration chamber 04 .

[0041] Optionally, the baffle is movably connected to the inner wall of the door body 12, and can selectively at least partially cover the opening of the first air duct 42 on the side close to the refrigeration chamber 04, so as to facilitate the air intake or air outlet at the outlet by adjusting the baffle, thereby improving the convenience of adjusting the air volume of the fan 02 and improving the user experience.

[0042] Optionally, the refrigeration component 03 is disposed outside the refrigeration cavity 04 , and the refrigeration component 03 performs heat transfer with the refrigeration cavity 04 through the box body 11 .

[0043] In one application scenario, the refrigeration component 03 is not connected to the refrigeration cavity 04, and the refrigeration cavity 04 is refrigerated by refrigerating the box body 11, so that the box body 11 forms a closed refrigeration cavity 04, improves the refrigeration and heat preservation effect in the refrigeration cavity 04, and has a simple structure, which is convenient for production and assembly.

[0044] In other embodiments, the refrigeration assembly includes refrigeration-related components such as a compressor, a condenser, a condensing fan, and an evaporator, which are arranged outside the refrigeration cavity. The evaporator cools the box body to transfer the cold to the refrigeration cavity. This heat transfer method is mainly natural convection heat transfer, which has a low heat transfer coefficient and a slow refrigeration speed. However, the fan is arranged in the refrigeration cavity in this application to enhance the convection effect of the airflow, thereby improving the refrigeration speed and refrigeration uniformity.

[0045] Optionally, the vehicle refrigerator further includes an adapter which is electrically connected to the refrigeration assembly 03 and / or the fan 02 in a detachable manner.

[0046] In one application scenario, the operating voltage of the car refrigerator is 12V DC. The adapter can convert AC power into 12V DC and electrically connect it to the refrigeration component 03 and / or the fan 02 to supply power to the refrigeration component 03 and / or the fan 02.

[0047] This setting can improve the multi-scenario adaptability of the car refrigerator and enhance the user experience; the detachable connection makes it easy to store.

[0048] Optionally, the vehicle refrigerator may further include a battery assembly, through which the refrigeration assembly 03 and / or the fan 02 may be electrically connected, thereby improving the portability of the vehicle refrigerator and improving the user experience.
