[0032] This utility model proposes a refrigerator designed to improve the temperature uniformity of a multi-cavity refrigerator. This refrigerator is typically mounted in a vehicle, but it can also be used independently, for example, as an outdoor refrigerator or a mini portable refrigerator. The following description focuses on its typical vehicle-mounted configuration.

[0033] In this application scenario, 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 utility model mainly targets air-cooling refrigerators, or composite refrigerators with air-cooling systems. The following description uses an air-cooled vehicle refrigerator as an example. This refrigerator includes a refrigerator body and an evaporator fan. The refrigerator body generally includes the cabinet and refrigeration system, which are the necessary components of a refrigerator.

[0034] Please see Figures 1 to 6 In embodiments of this utility model, the cabinet 100 is the main frame of the refrigerator 10. The cabinet 100 also typically serves as a mounting carrier for other components of the refrigerator 10. Generally, the cabinet 100 is also used for installation and fixation to the vehicle body. Furthermore, the cabinet 100 forms a storage cavity for storing food or other items. Further, the cabinet 100 typically includes an outer shell 110 and an inner shell 120, with an insulation space formed between the outer shell 110 and the inner shell 120. This insulation space is used to fill with insulation material and is typically the storage cavity.

[0035] In this embodiment, the number of storage cavities is multiple, for example, two, three, or four. When there are three storage cavities, all three cavities may share one fan, or two of the three storage cavities may share one fan. When there are four storage cavities, each of the four cavities may share one fan, or two or three of the four storage cavities may share one fan. The following description uses two storage cavities as an example; for ease of explanation, the first storage cavity 101 and the second storage cavity 102 will be used.

[0036] 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. The refrigeration system 200 typically includes components such as a compressor 210, a condenser 220, an evaporator 240, and an evaporator fan 260. The compressor 210, the condenser 220, and the evaporator 240 are interconnected to form a refrigerant circulation heat exchange loop. In some embodiments, the refrigeration system 200 also includes a condenser fan 230. Of course, in other embodiments, combined with switching devices such as valves and pipelines, the refrigeration system 200 can also be used as a heating system.

[0037] The evaporator fan 260, which is the fan located on one side of the evaporator 240 when the refrigerator 10 is used as a refrigeration device, drives air to flow inside the refrigerator 10. In addition, by accelerating the air flow, the evaporator fan 260 can also promote the heat exchange process of the evaporator 240. The fan makes the cold air pass through the evaporator 240 more quickly, improving the evaporation efficiency of the refrigerant, thereby improving the refrigeration capacity of the refrigerator 10. The evaporator fan 260 usually includes a fan and its mounting components. The fan can be an axial fan or a centrifugal fan. Preferably, in this embodiment, an axial fan is preferred.

[0038] Please see Figures 1 to 6 In one embodiment of the present invention, the refrigerator 10 includes a refrigerator body 11 and an evaporator fan 260, and is provided with a first storage cavity 101 and a second storage cavity 102, a first air outlet 103 communicating with the first storage cavity 101, and a second air outlet 104 communicating with the second storage cavity 102; the evaporator fan 260 is disposed on the refrigerator body 11, and the air outlet side of the evaporator fan 260 is respectively connected to the first air outlet 103 and the second air outlet 104.

[0039] The first air outlet 103 is connected to the first storage cavity 101. It can be understood that the first air outlet 103 is set on the shell that constitutes the first storage cavity 101. For the first storage cavity 101, the first air outlet 103 is actually the cold air inlet of the first storage cavity 101. The cold air after passing through the evaporator fan 260 enters the first storage cavity 101 after exiting through the first air outlet 103.

[0040] The second air outlet 104 is connected to the second storage cavity 102. It can be understood that the second air outlet 104 is set on the shell that constitutes the second storage cavity 102. For the second storage cavity 102, the second air outlet 104 is actually the cold air inlet of the second storage cavity 102. After passing through the evaporator fan 260, the cold air passes through the guide air duct and comes out from the first air outlet 103 and enters the first storage cavity 101.

[0041] The air outlet side of the evaporator fan 260 is connected to the first air outlet 103 and the second air outlet 104 respectively. In this embodiment, it can be understood that the air outlet side of the evaporator fan 260 is directly connected to the first air outlet 103 and the second air outlet 104, or that the air outlet side of the evaporator fan 260 is connected to the first air outlet 103 and the second air outlet 104 through a very short air duct.

[0042] The technical solution of this utility model connects the air outlet side of the evaporator fan 260 to the first air outlet 103 and the second air outlet 104 respectively. The first air outlet 103 is connected to the first storage cavity 101, and the second air outlet 104 is connected to the second storage cavity 102. In this way, the two storage cavities can directly obtain cold airflow through the evaporator fan 260, which can reduce the uneven distribution of cold energy caused by a long or unreasonable cold air flow path, thereby improving the temperature uniformity between the first storage cavity 101 and the second storage cavity 102.

[0043] In one embodiment, in order to further improve the temperature uniformity between the first storage cavity 101 and the second storage cavity 102, the volume of the first storage cavity 101 is greater than the volume of the second storage cavity 102, and the opening area of ​​the first air outlet 103 is greater than the opening area of ​​the second air outlet 104.

[0044] Regarding the opening area, the opening area of ​​the first air outlet 103 can be understood as the effective air passage area between the evaporator fan 260 and the first storage cavity 101; the opening area of ​​the second air outlet 104 is the effective air passage area between the evaporator fan 260 and the second storage cavity 102.

[0045] The first storage chamber 101 has a larger volume and a higher demand for cooling, so a larger air outlet area allows more cooling air to flow into the first storage chamber 101; while the second storage chamber 102 has a relatively smaller volume and a smaller air outlet area, which can reduce the excessive entry of cooling air and prevent its temperature from becoming too low.

[0046] This embodiment limits the distribution of cold airflow by defining the volume of the first storage cavity 101 and the second storage cavity 102, and the relationship between the first air outlet 103 and the second air outlet 104, so that the temperature distribution in the two cavities is more uniform.

[0047] In another embodiment, in order to further improve the temperature uniformity between the first storage cavity 101 and the second storage cavity 102, the area ratio of the opening areas of the first air outlet 103 and the second air outlet 104 is defined as K, and the volume ratio of the first storage cavity 101 and the second storage cavity 102 is defined as N. The ratio between K and N is not less than 0.8 and not greater than 1.2.

[0048] The ratio between K and N can be 0.8, 0.9, 1.0, 1.1 or 1.2.

[0049] In an air-cooled system, the role of the cold airflow is to remove heat through air movement, thereby lowering the temperature of the storage cavity. The airflow helps to cool the air and exchange heat with heat sources in the storage cavity (such as food, inner walls, etc.). It is evident that the size and flow pattern of the airflow have a crucial impact on the transfer of cold energy.

[0050] If the first storage cavity 101 has a larger volume, the first air outlet 103 is provided with a correspondingly larger opening area, which allows more cold air to flow into the first storage cavity 101. Conversely, if the second storage cavity 102 has a smaller volume, the second air outlet 104 is provided with a correspondingly smaller opening area, which allows less cold air to flow into the second storage cavity 102. This can reduce overcooling or temperature fluctuations between the two storage cavities. Accordingly, the area ratio of the opening areas of the first air outlet 103 and the second air outlet 104 is K, and the volume ratio of the first storage cavity 101 and the second storage cavity 102 is N. When K and N are within a range of 1.0, the cooling capacity of the refrigeration system 200 can be better distributed.

[0051] Furthermore, the airflow pattern is typically related to the first storage cavity 101 and the second storage cavity 102. For example, the first storage cavity 101 and the second storage cavity 102 are connected, and the second storage cavity 102 is located above the first storage cavity 101. When the volume of the first storage cavity 101 is greater than the volume of the second storage cavity 102, the ratio between K and N can be set to 0.8 or 0.9. That is, compared to a ratio of 1.0 between K and N, this embodiment allocates slightly more airflow to the second storage cavity 102. Since cold air sinks, the cold air passing through the second storage cavity 102 will also pass through the first storage cavity 101. In this scenario, this setting can also improve the temperature uniformity between the first storage cavity 101 and the second storage cavity 102.

[0052] Furthermore, when there is a large volume difference between the first storage cavity 101 and the second storage cavity 102, for example, the volume of the first storage cavity 101 is 40L and the volume of the second storage cavity 102 is 10L, the first storage cavity 101 and the second storage cavity 102 are arranged side by side in the horizontal direction. In this case, the ratio between K and N can be set to 1.1 or 1.2. That is, compared to a ratio between K and N of 1.0, this embodiment allocates slightly more airflow to the first storage cavity 101, which can accelerate the circulation of cold air in the first storage cavity 101. In this scenario, this setting can also improve the temperature uniformity between the first storage cavity 101 and the second storage cavity 102.

[0053] In this embodiment, the area ratio of the opening areas of the first air outlet 103 and the second air outlet 104 is defined as K, and the volume ratio of the first storage cavity 101 and the second storage cavity 102 is defined as N. The ratio between K and N is not less than 0.8 and not greater than 1.2. In this way, the distribution of cold air in the refrigerator 10 is further optimized, thereby improving the temperature uniformity of the storage cavity.

[0054] In one embodiment, the refrigerator body 11 includes an outer shell 110, an inner shell 120 disposed in the outer shell 110, and an air duct partition 140 disposed in the inner shell 120; the inner shell 120 forms a first storage cavity 101 and a second storage cavity 102, the first air outlet 103 and the second air outlet 104 are disposed in the air duct partition 140, and an installation cavity 105 is formed between the air duct partition 140 and the inner shell 120, and the evaporator fan 260 is disposed in the installation cavity 105 corresponding to the positions of the first air outlet 103 and the second air outlet 104.

[0055] The outer casing 110 typically serves as the external protective and support structure of the refrigerator, protecting the impeller 261, the air duct partition 140, and other components from external damage. At the same time, the outer casing 110 helps maintain the structural stability of the entire refrigerator and reduces the loosening of components caused by external forces such as vibration.

[0056] The inner shell 120 is located inside the outer shell 110 and is mainly used to divide and isolate different functional areas (first storage cavity 101 and second storage cavity 102 or mounting cavity 105) or air duct space. The inner shell 120 can help to effectively guide airflow, organize air flow and form appropriate air flow channels.

[0057] The air duct baffle 140 serves to separate airflow channels within the refrigerator body 11. The main purpose of the air duct baffle 140 is to differentiate between exhaust and return air, allowing the cold air generated by the evaporator fan 260 to be smoothly delivered to target areas (e.g., the first storage compartment 101 and the second storage compartment 102), thereby improving airflow efficiency. The air duct baffle 140 and the inner shell 120 enclose a mounting cavity 105, in which the evaporator fan 260 is located. This mounting cavity 105 also communicates with the return air vent to form an internal circulation air duct within the refrigerator. Thus, by installing the evaporator fan 260 within the mounting cavity 105, direct contact between the evaporator fan 260 and other components is reduced. Furthermore, installing the evaporator fan 260 within the air duct baffle facilitates its installation.

[0058] An insulation space is formed between the outer shell 110 and the inner shell 120, which is used to fill insulation material. The air duct partition 140 divides the inner shell 120 into a storage cavity and an installation cavity 105. The evaporator fan 260 and the evaporator 240 of the refrigeration system 200 are located in the installation cavity 105. The evaporator 240 is located on the air inlet side of the evaporator fan 260. The evaporator fan 260 can be installed on the inner shell 120 or on the air duct partition 140. The first air outlet 103 and the second air outlet 104 are located on the air duct partition 140. That is, the air duct partition 140 provides the first air outlet 103 corresponding to the first storage cavity 101 and the air duct partition 140 provides the second air outlet 104 corresponding to the second storage cavity 102. Providing the first air outlet 103 and the second air outlet 104 on the air duct partition 140 makes it easier to process.

[0059] Furthermore, the evaporator fan 260 is positioned on the duct partition 140 corresponding to the positions of the first air outlet 103 and the second air outlet 104. The evaporator fan 260 being positioned on the duct partition 140 facilitates the installation of the fan and shortens the airflow path between the evaporator fan 260 and the first storage chamber 101 and the second storage chamber 102, thereby improving the efficiency of the refrigeration system 200.

[0060] In an exemplary embodiment, the evaporator fan 260 includes an air guide ring 262 and a fan wheel 261 disposed on the air guide ring 262. The air outlet end of the air guide ring 262 is disposed on the air duct partition 140 at a position corresponding to the first air outlet 103 and the second air outlet 104.

[0061] The airflow can be adjusted by changing the angle of the fan blades, thereby controlling the flow rate and contributing to a more uniform temperature distribution and improved cooling efficiency inside the refrigerator 10.

[0062] In this embodiment, the air outlet of the air guide ring 262 is located on the air duct partition 140, which can further shorten the airflow path between the evaporator fan 260 and the first storage chamber 101 and the second storage chamber 102, thereby improving the efficiency of the refrigeration system 200.

[0063] In one embodiment, the refrigerator body 11 includes a partition 130, which is disposed inside the inner shell 120. The two sides of the partition 130 and the inner shell 120 respectively form the first storage cavity 101 and the second storage cavity 102.

[0064] The partition plate 130 and the inner shell 120 can be fixedly connected or detachably connected. Preferably, the partition plate 130 and the inner shell 120 are detachably connected. The detachable connection between the partition plate 130 and the inner shell 120 can be a plug-in, snap-fit, or threaded connection. Preferably, the partition plate 130 and the inner shell 120 are snap-fit.

[0065] In this embodiment, the partition 130 is provided so that the first storage cavity 101 and the second storage cavity 102 form two relatively independent storage cavities, which can reduce the mutual influence between the items stored in the two storage cavities.

[0066] In one embodiment, in order to further improve the temperature uniformity between the first storage cavity 101 and the second storage cavity 102, the partition plate 130 is provided with a communication port 131, through which the first storage cavity 101 and the second storage cavity 102 are connected.

[0067] In this embodiment, the first storage cavity 101 and the second storage cavity 102 are connected through the communication port 131, that is, an airflow channel is formed between the two storage cavities. In this way, cold air can flow from one storage cavity to the other, promoting the natural flow of cold air between the two cavities and reducing the cold air being confined to only one storage cavity. Through this airflow exchange, the temperature uniformity between the two storage cavities can be improved, reducing local overcooling or overheating; thereby improving the temperature uniformity between the first storage cavity 101 and the second storage cavity 102.

[0068] In one embodiment, please refer to Figure 3 The second storage cavity 102 is located above the first storage cavity 101.

[0069] In this embodiment, the second storage cavity 102 is placed above the first storage cavity 101, which can utilize vertical space and reduce the floor space occupied by the refrigerator. The refrigerator 10 is usually limited by the interior space of the vehicle. This arrangement helps to improve the space utilization efficiency and facilitates the design of more storage space in a limited space.

[0070] In one embodiment, the evaporator fan 260 is located around the first storage cavity 101 and the second storage cavity 102. The location of the evaporator fan 260 around the first storage cavity 101 and the second storage cavity 102 makes the cold air flow path more direct and efficient. After the cold air is discharged from the fan, it can flow smoothly to the second storage cavity 102 and the area above it, and then enter the first storage cavity 101 through natural flow. This helps to improve the uniformity of airflow, thereby making the temperature distribution in the two storage cavities more uniform.

[0071] This utility model 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 this 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.

The vehicle typically includes a vehicle body, which usually comprises a chassis, engine, transmission system, braking system, steering system, running system, fuel system, cooling system, electrical instrumentation system, and safety protection devices.

[0073] The vehicle body is the main part of the vehicle, consisting of the roof, floor, side walls, and doors. Its main function is to provide a cabin for passengers to sit in.

[0074] In some embodiments, the vehicle cabin has a driver's seat and a passenger seat, and the refrigerator 10 is located between the driver's seat and the passenger seat.
