[0008] The technical solutions of the embodiments of this application will be described clearly and completely below with reference to the drawings of the embodiments of this application. To be understood, the embodiments described are only a part of, and not all, of, the embodiments of this application. All other embodiments that a person skilled in the art can obtain based on the embodiments of this application without requiring inventive work are all within the scope of protection of this application.

[0009] In the embodiments of this application, all direction indicators (up, down, left, right, front, back, etc.) are used solely to describe the relative positional relationships between each component in a particular posture (as shown in the drawings), sports situations, etc., and the direction indicators change accordingly when the particular posture changes.

[0010] The terms “First,” “Second,” and “Third” in this application are used for descriptive purposes only and should not be understood as indicating the number of technical features described. Therefore, features defined as “First,” “Second,” and “Third” may explicitly or implicitly include at least one of these features. Furthermore, while technical solutions between each embodiment can be combined with one another, it is assumed that they are implementable by a person skilled in the art. If a combination of technical solutions is inconsistent or impractical, such a combination should be considered nonexistent and outside the scope of protection sought by this application.

[0011] As shown in Figures 1 to 6, this application first provides an in-vehicle refrigerator. Figure 1 is a schematic diagram of the structure of one embodiment of the in-vehicle refrigerator of this application. Figure 2 is a schematic side view of the embodiment of Figure 1. Figure 3 is a schematic diagram of the structure of one embodiment of the door and axial fan of this application. Figure 4 is a schematic bottom view of one embodiment of the door and axial fan of this application. Figure 5 is a schematic diagram of the structure of one embodiment of the door and centrifugal fan of this application. Figure 6 is a schematic bottom view of one embodiment of the door and centrifugal fan of this application. The in-vehicle refrigerator includes a casing 11, a door 12, a fan 02, and a refrigeration assembly 03. The casing 11 has a freezer compartment 04 and a first opening communicating with the freezer compartment 04. The door 12 can movably cover the first opening, the fan 02 is located on the side of the door 12 closer to the freezer compartment 04, and the refrigeration assembly 03 is attached to the casing 11 and used to cool the freezer compartment 04.

[0012] Specifically, the fan 02 operates inside the freezer compartment 04, and the fan 02 can enhance the convection effect of the airflow inside the freezer compartment 04, thereby increasing the convection of the airflow inside the freezer compartment 04 without communicating with the outside airflow. Furthermore, the intensity of the convection can be adjusted by adjusting the wind speed of the fan 02.

[0013] In some embodiments, the fan 02 may operate synchronously with the refrigeration assembly 03 or asynchronously, and there are no specific limitations. The fan 02 can enhance the convection of airflow within the freezer chamber 04. Therefore, it is not necessary to provide an externally connected vent in the freezer chamber 04, and the convection effect of the airflow within the chamber can be enhanced. For example, in the manufacturing assembly process, the fan 02 and the refrigeration assembly 03 may be assembled separately, and the refrigeration assembly 03 may operate independently to enhance the convection effect of airflow within the freezer chamber 04. Therefore, the method of cooling the refrigeration assembly is not limited in this application. For example, in an application scenario, as shown in Figure 1, the refrigeration assembly 03 includes a refrigeration component 31 (e.g., a compressor) and an evaporator (not shown). The refrigeration component 31 includes a compressor, a condenser, a condenser fan, etc. The evaporator is located outside the freezer chamber 04, and the freezer chamber 04 can be cooled by cooling the enclosure 11.

[0014] For example, in other application scenarios (not shown), the refrigeration assembly can be placed in a freezer box in a freezer room, etc., and is not particularly limited.

[0015] The advantages of the above configuration are as follows: The placement of fan 02 enhances the convection effect of the airflow in the freezer compartment 04, improving the uniformity and speed of cooling within the freezer compartment 04, and thus improving the cooling effect. Furthermore, fan 02 is positioned on the side of the door 12 closest to the freezer compartment 04, making assembly and operation of fan 02 convenient. Moreover, fan 02 is positioned on the side of the door 12 closest to the freezer compartment 04, which is convenient for enhancing the convection effect of the airflow within the freezer compartment 04. The refrigeration assembly 03 is attached to the box 11, thereby improving the positional stability of the refrigeration assembly 03 and improving the reliability of the vehicle refrigerator.

[0016] Selectively, a groove is formed in the inner wall of the door body 12 that penetrates the freezer compartment 04, and the fan 02 is positioned at least partially within the mounting chamber formed by the groove.

[0017] Optionally, a groove penetrating the freezer compartment 04 is formed on the inner wall of the door body 12. The fan 02 is arranged in the mounting chamber formed by the groove, thereby reducing the interference of the fan 02 with the usable space in the freezer compartment 04. The fan 02 is arranged in the mounting chamber formed by the groove, thereby improving the stability of the fan 02 and reducing the influence of external interference on the fan 02. Further, since the groove is formed on the inner wall of the door body 12, the groove and the inner wall can be integrally formed, thereby improving the stability of the groove.

[0018] Optionally, the fan 02 can be completely arranged in the mounting chamber formed by the groove, thereby further improving the interference resistance performance of the fan 02 and the aesthetics of the in-vehicle refrigerator.

[0019] Optionally, the fan 02 is installed at a distance from the side wall 411 of the groove, thereby forming a first air duct 42 communicating with the freezer compartment 04.

[0020] The first air duct 42 improves the communication effect between the air intake and / or exhaust port of the fan 02 and the freezer compartment 04, and thus can improve the effect of promoting the convection of the air flow in the freezer compartment 04 by the fan 02. The fan 02 is arranged at a distance from the side wall 411 of the groove, that is, a first air duct 42 communicating with the freezer compartment 04 is formed. This design structure is simple, does not require complicated manufacturing design, and can reduce the manufacturing and assembly costs.

[0021] In another embodiment, the fan is arranged at least partially at a distance from the side wall of the groove, and a first air duct and a through hole communicating with the freezer compartment may be provided in the area where the fan is not arranged at a distance.

[0022] Optionally, as shown in FIGS. 3 and 4, the fan 02 includes an axial flow fan 21. The axial flow fan 21 is arranged at a distance from the bottom wall 412 of the groove, thereby forming a second air duct 43 communicating the air vent of the axial flow fan 21 with the first air duct 42.

[0023] Due to the design of the impeller and blades of the axial flow fan 21, when the airflow flows out of the fan's exhaust port, it flows out almost parallel to the rotation axis of the blades, and the intake port 211 and exhaust port 212 of the axial flow fan 21 are arranged in a straight line along a straight line parallel to the rotation axis of the blades. The axial flow fan 21 is easy to install. By providing the second air duct 43, the intake port 211 of the axial flow fan 21 can be easily connected to the first air duct 42 via the second air duct 43, and can also be connected to the freezer chamber 04, improving the airflow effect of the axial flow fan 21. In addition, by providing the first air duct 42 and the second air duct 43, the airflow that has passed through the first air duct 42 changes direction and flows into the second air duct 43, making it easier for the airflow to flow into the intake port 211 of the axial flow fan 21. Furthermore, by arranging the axial fan 21 and the bottom wall 412 of the groove with a gap between them, a second air duct 43 can be formed, resulting in a simple structure that is easy to manufacture and assemble.

[0024] Selectively, the specific shape of the groove is not restricted; for example, the inner wall of the groove can be made streamlined, thereby enhancing the airflow duct's effectiveness, reducing resistance, and saving power.

[0025] Selectively, the shape of the connection between the side wall 411 of the groove and the bottom wall 412 of the groove may be arc-shaped or streamlined. This improves the smoothness of the airflow when it switches from the first air duct 42 to the second air duct 43, thereby reducing resistance.

[0026] Selectively, the side walls 411 and bottom wall 412 of the groove are arranged at an obtuse angle, thereby the inner diameter of the groove gradually increases along the direction in which the bottom wall faces the freezer chamber 04, which is convenient for the airflow to enter the axial fan 21 through the first air duct 42 and the second air duct 43.

[0027] Selectively, as shown in Figures 5 and 6, the fan 02 is equipped with a centrifugal fan 22, and the side walls 411 and bottom walls 412 of the groove are arranged at an obtuse angle, thereby the inner diameter of the groove gradually increases along the direction in which the bottom wall faces the freezer chamber 04.

[0028] The centrifugal fan 22 is a fan that transports airflow using centrifugal force. Its operating principle is to draw airflow into the fan through a rotating impeller, accelerate the airflow with the impeller blades, and push the airflow out to the exhaust port by centrifugal force, thereby achieving airflow transport and pressurization. The centrifugal fan 22 can achieve greater wind pressure and airflow volume, resulting in a stronger convection effect. The exhaust port 221 of the centrifugal fan 22 is perpendicular to the intake port 222, and the side walls 411 and bottom wall 412 of the groove are set at an obtuse angle, so that the inner diameter of the groove gradually increases in the direction in which the bottom wall faces the freezer chamber 04. This is convenient for guiding and redirecting the airflow discharged from the exhaust port 221 of the centrifugal fan 22, reducing wind pressure loss when the airflow flows out of the installation chamber through the first air duct 42 from the exhaust port 221, and improving the convection effect.

[0029] The angle between the side wall 411 and the bottom wall 412 of the groove can be selectively designed as needed, and different airflow induction and redirection effects can be obtained by using different angles.

[0030] Selectively, the side walls 411 of the groove may be curved structures. This allows the airflow discharged from the exhaust port of the centrifugal fan 22 to be guided and to flow out through the mounting chamber formed by the groove.

[0031] In some embodiments, selectively, the exhaust port 221 of the centrifugal fan 22 is perpendicular to the intake port 222, so that a gap does not need to be provided between the centrifugal fan and the bottom wall 412 of the groove, thereby improving the degree of integration of the in-vehicle refrigerator and improving the space utilization rate of the freezer compartment.

[0032] Selectively, the in-vehicle refrigerator further comprises a first baffle 05 movably connected to the fan 02, the first baffle 05 selectively at least partially covering the opening of the first air duct 42 on the side closer to the freezer compartment 04.

[0033] Selectively, the first baffle 05 is movably connected to the fan 02 and selectively covers, at least partially, the opening of the first air duct 42 on the side closer to the freezer chamber 04. This allows the first baffle 05 to be adjusted, opening This achieves the desired intake or exhaust volume, improving the convenience of adjusting the airflow of fan 02 and enhancing the user experience.

[0034] Selectively, as shown in Figure 1, the vehicle refrigerator further comprises a first baffle 05 that is movably connected to the inner wall of the door body 12, the first baffle 05 selectively covers at least partially the opening of the first air duct 42 on the side closer to the freezer compartment 04.

[0035] Selectively, the first baffle 05 is movably connected to the inner wall of the door body 12 and selectively covers at least partially the opening of the first air duct 42 on the side closer to the freezer compartment 04. This allows the first baffle 05 to be adjusted, opening This achieves the desired intake or exhaust volume, improving the convenience of adjusting the airflow of fan 02 and enhancing the user experience.

[0036] The refrigeration assembly 03 is located outside the freezer chamber 04, and the refrigeration assembly 03 transfers heat to the freezer chamber 04 via the box 11.

[0037] In one application scenario, the refrigeration assembly 03 is not connected to the freezer chamber 04, and the freezer chamber 04 is cooled by cooling the box body 11. This allows the box body 11 to form a sealed freezer chamber 04, improving the cooling and heat retention effect within the freezer chamber 04, while also being simple in structure and easy to manufacture and assemble.

[0038] In other embodiments, the refrigeration assembly includes refrigeration-related components such as a compressor, condenser, condensing fan, and evaporator, which are located outside the freezer chamber. The evaporator cools the enclosure and transfers cold air to the freezer chamber. This heat transfer method is primarily convective heat transfer, resulting in a low heat transfer coefficient and slow cooling rate. In this application, a fan is placed inside the freezer chamber to enhance the convective effect of the airflow, thereby improving the cooling rate and cooling uniformity.

[0039] In one application scenario, the operating voltage of the in-car refrigerator is 12V DC. The adapter converts the AC power supply to 12V DC and is electrically connected to the refrigeration component 03 and / or fan 03, enabling power supply to the refrigeration component 03 and / or fan 02.

[0040] This configuration improves the adaptability of the in-car refrigerator to various applications and enhances the user experience. The detachable connection is convenient for storage.

[0041] Selectively, the in-car refrigerator also includes a battery assembly, and the battery assembly teeth Refrigeration assembly 03 and / or fan 02 and Electrically connected So This improves the portability and user experience of in-car refrigerators.

[0042] Selectively, fan 02 includes an activation switch, allowing the user to manually control the opening and closing of fan 02 via the activation switch. Furthermore, fan 02 includes a wind speed adjustment switch, which allows the user to easily adjust and control the wind speed, thereby achieving energy savings.

[0043] Selectively, the in-car refrigerator is equipped with a handle, which is installed on the box body 11, allowing the user to conveniently move the in-car refrigerator and improving the user experience.

[0044] Selectively, the refrigeration component 03 includes refrigeration-related components such as a compressor, condenser, capillary tube, evaporator, condensing fan, and door fan, thereby achieving cooling of the freezer compartment 04.

[0045] Selectively, a power interface is provided on the enclosure 11, and the power interface is located on the enclosure 11, and the refrigeration component 03 and / or fan 02 are electrically connected to an external power system via the power interface. The power interface is electrically connected to an external power system such as a vehicle charger, enabling power supply to the refrigeration component 03 and / or fan 02.

[0046] Selectively, a vehicle refrigerator includes a controller. The controller is electrically connected to the battery assembly, power interface or adapter, fan, compressor, condenser fan, etc., and controls the operation of these components.

[0047] Selectively, the vehicle's onboard charger's 12V / 24V power supply can be used to power the onboard refrigerator.

[0048] Unlike prior art, the vehicle refrigerator of this application comprises a casing, a door, a fan, and a refrigeration assembly. The casing has a freezer compartment and a first opening communicating with the freezer compartment. The door cover is positioned to cover the first opening, the fan is positioned on the side of the door closest to the freezer compartment, and the refrigeration assembly is mounted on the casing and used to cool the freezer compartment. The installation of the fan enhances the convection effect of the airflow in the freezer compartment, improving the uniformity and rate of cooling in the freezer compartment and enhancing the cooling effect. Furthermore, the fan is positioned on the side of the door closest to the freezer compartment for convenience in assembly and operation. The fan is also positioned on the side of the door closest to the freezer compartment for convenience in enhancing the convection effect of the airflow in the freezer compartment. Because the refrigeration assembly is mounted on the casing, the positional stability of the refrigeration assembly is improved, and the reliability of the vehicle refrigerator is enhanced.

[0049] Furthermore, in any of the embodiments corresponding to Figures 1 to 6 above, similar improvements can be made to the in-vehicle refrigerator by referring to any of the embodiments corresponding to Figures 7 to 11 below.

[0050] For example, in embodiments corresponding to Figures 7 to 11 below, the circulation fan 5 can supply power to the airflow. In the above embodiments, the fan 02 can supply power to the airflow, and any of the fan 02 in the above embodiments can be improved by referring to specific embodiments of the operating principle of the circulation fan 5 in the following embodiments, the method of connecting to other components, and other related technical features. Also, for example, in the following embodiments, the cold air circulation cover plate 3 can be used to install the circulation fan 5, and in the above embodiments, the door body 12 can be used to install the fan 02, and any of the door body 12 in the above embodiments can be improved by referring to specific embodiments of other related technical features of the cold air circulation cover plate 3 in the following embodiments, the method of connecting to other components, and other related technical features. Referencing these examples, other improvements to the in-vehicle refrigerator will not be repeated.

[0051] In any of the following embodiments, similar improvements can be made to the in-vehicle refrigerator by referring to any one embodiment corresponding to Figures 1 to 6 described above, and this will not be repeated here.

[0052] In conventional technology, a vehicle-mounted refrigerator refers to a refrigerator that can be installed in a car. Vehicle-mounted refrigerators are a new generation of refrigeration and freezing equipment that has become popular in the international market in recent years, and are generally compressor-type vehicle-mounted refrigerators. Compressors are a traditional technology of conventional refrigerators, offering low freezing temperatures (-18 to 10 degrees Celsius), high freezing efficiency, the ability to make ice to maintain freshness, and a large volume, which is the future development trend for vehicle-mounted refrigerators.

[0053] Conventional technology has the following drawbacks: During use of conventional in-car refrigerators, the cold air generated after freezing flows slowly between the freezer and refrigerator compartments, resulting in a fast airflow that hinders rapid circulation of cold air in the freezer compartment. This leads to low freezing efficiency and is disadvantageous for improving freezing efficiency with the same amount of power. It is also disadvantageous for rapid diffusion of cold air and heat exchange.

[0054] As shown in Figures 7 to 9, this application further provides an in-vehicle refrigerator. This specific embodiment employs the following technical solution. The in-vehicle refrigerator comprises an in-vehicle refrigerator body 1, a side panel 2, and a cold air circulation cover plate 3. Here, an inwardly recessed air intake chamber 4 is provided in the inner center of the cold air circulation cover plate 3, and a circulation fan 5 is fixed in the center of the inwardly recessed air intake chamber 4. Here, the inwardly recessed air intake chamber 4 corresponds to the groove in the above embodiment, and the cold air circulation cover plate 3 corresponds to the door body 12 in the above embodiment.

[0055] In some embodiments, as shown in Figure 8, a second baffle 6 is fixed to the surface of the concave air intake chamber 4, a one-cycle intake grille 7 is arranged around the outer circumference of the second baffle 6, exhaust holes 8 are arranged in a matrix pattern in the center of the second baffle 6, the exhaust holes 8 are installed in contact with the central exhaust port of the circulation fan 5, and the intake grille 7 is in communication with the concave air intake chamber 4.

[0056] Specifically, referring to Figure 8, in this embodiment, the in-vehicle refrigerator further includes a second baffle 6, which is installed to cover the opening of a groove (concave air intake chamber 4) in the inner wall of the door body (cold air circulation cover plate 3), a fan (corresponding to a circulation fan 5) is placed in the groove, an intake grille 7 communicating with the groove is provided on the outer circumference of the second baffle 6, and an exhaust port 8 communicating with the fan's exhaust port is provided in the center of the second baffle 6. Furthermore, the intake grille 7 can be arranged to surround the exhaust port 8, and the exhaust port 8 can also be arranged to be in contact with the central exhaust port of the fan. In other words, the area in which the fan is installed in contact with the second baffle 6 is provided with the fan's exhaust port and an exhaust port 8 communicating with the freezer compartment.

[0057] Here, the fan (circulation fan 5) is installed at least partially spaced from the side wall of the groove, thereby forming a first air duct 42. The airflow passes through the intake grille 7 and flows sequentially through the first air duct 42, the fan's intake port, the exhaust port in the center of the fan, and the matrix-distributed exhaust holes 8 before entering the freezer. The first air duct 42 can be determined to connect the fan's intake port and the intake grille 7.

[0058] In some embodiments, the circulation fan 5 is a drum-type turbine structure and has a lateral intake and downward discharge structure.

[0059] In some embodiments, referring to Figure 7, one side of the cold air circulation cover plate 3 first An induction sensor 9 is provided, first The induction sensor 9 is inductively integrated with the side panel 2 to enable the start and stop control of the circulation fan 5. It is also located on the inner edge of the cold air circulation cover plate 3. second Induction sensor 9 1 is provided, second Induction sensor 9 1 is connected to a logo light and other electronic control devices.

[0060] Specifically, referring to Figure 7, in this embodiment, the in-vehicle refrigerator is first It is further equipped with an induction sensor 9. first The induction sensor 9 is located on one side of the door body (cold air circulation cover plate 3) and is used to control the starting and stopping of the fan (circulation fan 5).

[0061] Furthermore, the in-car refrigerator comprises a box body and a door body (cold air circulation cover plate 3), and the box body comprises the in-car refrigerator main unit 1 and side panels 2. first The induction sensor 9 is inductively coupled with the side panel 2, thereby controlling the starting and stopping of the fan (circulation fan 5).

[0062] Furthermore, the in-car refrigerator, second Induction sensor 9It also includes 1 and a second electrical control device (corresponding to the aforementioned logo light or other electrical control devices). second Induction sensor 9 1 is located on the inner edge of the door body (cold air circulation cover plate 3) and is used to control the starting and stopping of the second electrical control device.

[0063] Furthermore, in some embodiments, a sealing ring is provided between the exhaust port and exhaust hole 8 of the circulation fan 5 to isolate the intake grille 7 from the exhaust hole 8. In some embodiments, four sets of extension connecting columns, which are fitted with bolts, are provided on the back of the second baffle 6 to fix the second baffle 6 to the concave air intake chamber 4.

[0064] Specifically, in this embodiment, the in-vehicle refrigerator also includes a sealing ring. The sealing ring is positioned between the exhaust port and exhaust hole 8 of the fan (circulation fan 5) and is used to isolate the intake grille 7 from the exhaust hole 8.

[0065] In some embodiments, one side of the sealing ring abuts against the fan side closer to the second baffle 6, and the other side abuts against the second baffle 6. The sealing ring surrounds the exhaust port 8 and the fan's exhaust port, thereby isolating the intake grille 7 from the exhaust port 8 and reducing interference with the exhaust from the exhaust port 8.

[0066] Furthermore, in some embodiments, the intake and exhaust modes of the exhaust port 8 and intake grille 7 can be reversed by reversing the operation of the circulation fan 5. That is, when the circulation fan 5 is reversed, the exhaust port 8 is used as the intake side and the intake grille 7 is used as the exhaust side.

[0067] The operating principle of this specific embodiment is as follows: the compressor inside the vehicle refrigerator body 1 works in cooperation with the evaporator to cool the inside of the box, and the circulation fan 5 sends air to the center of the vehicle refrigerator body 1, causing the cold air to rise from all sides and flow into the inside of the circulation fan 5 from the intake grille 7, forming internal circulation. As a result, the cold air accumulated at the bottom can fill the entire freezer compartment.

[0068] After adopting the above structure, the beneficial effects of this application are as follows: By installing a circulation fan in the refrigerator door, the airflow velocity of the cold air inside the refrigerator compartment is increased, improving freezing efficiency. Furthermore, by adopting a design with a wide intake passage and a narrow exhaust passage, the initial velocity of the cold air outlet is increased, expanding the cold air circulation range. At the same time, a sufficient intake volume prevents the generation of wind noise caused by the intake of cold air.

[0069] As shown in Figures 7-11, the present application further provides an in-vehicle refrigerator.

[0071] In some embodiments, the circulation fan 5 is a drum-type turbine structure and has a lateral intake and downward discharge structure. In some embodiments, on one side of the cold air circulation cover plate 3 first An induction sensor 9 is provided, firstThe induction sensor 9 is inductively integrated with the side panel 2 to enable starting and stopping control of the circulation fan 5.
