[0035] Currently, the traditional installation method for household air-cooled refrigerators is to install the evaporator on the cabinet and the fan on the air duct cover. Both the evaporator and the fan have plug-in terminals, which are plugged into the sockets of the circuit components inside the cabinet 10. When a traditional air-cooled refrigerator is set up as a vehicle-mounted air-cooled refrigerator, the internal space of the vehicle refrigerator is small and the air duct cover is large, making it inconvenient to plug in the fan terminals. In addition, after plugging in, a long wire will be left behind the air duct cover, which is difficult to handle.

[0036] This utility model proposes a refrigerator 100 that can improve the ease of installation of the evaporator 32 and the fan 33 in the small space inside the vehicle refrigerator 100.

[0037] Please see Figures 1 to 4In one embodiment of the present invention, the refrigerator 100 includes a cabinet 10, an air duct shell 20, and a heat exchange assembly 30; the cabinet 10 has a storage compartment, the air duct shell 20 is installed on the cabinet 10 and communicates with the storage compartment, the heat exchange assembly 30 is disposed inside the air duct shell 20, the heat exchange assembly 30 includes a bracket 31 and an evaporator 32 and a fan 33 installed on the bracket 31, the bracket 31 is detachably installed on the air duct shell 20, and the fan 33 is used to allow air inside the air duct shell 20 to pass through the evaporator 32 and be sent into the storage compartment.

[0038] In this invention, the refrigerator 100 can be configured as a vehicle-mounted refrigerator 100. The storage compartment of the cabinet 10 can serve as a container for storing food. The evaporator 32 and the fan 33 can be installed on the same side of the bracket 31 or on opposite sides of the bracket 31, as long as the fan 33 faces the evaporator 32. The fan 33 can be configured as an axial flow fan, and the fan 33 can face the evaporator 32. This can be either the air inlet of the fan 33 facing the evaporator 32 or the air outlet of the fan 33 facing the evaporator 32. Since the air duct shell 20 connects to the storage compartment, when the fan 33 faces the evaporator 32, it can guide the airflow inside the air duct shell 20 through the evaporator 32 and into the storage compartment. When the evaporator 32 absorbs heat through evaporation, the flowing air can carry away the heat in the storage compartment, thereby realizing the air-cooling function of the refrigerator 100.

[0039] Since the evaporator 32 and the fan 33 are both pre-installed on the bracket 31, the evaporator 32 and the fan 33 can be assembled into a single heat exchange component 30 through the bracket 31. The heat exchange component 30 can be assembled by simply installing this component inside the air duct shell 20 and then installing the air duct shell 20 on the housing 10. There is no need to install the fan 33 and the evaporator 32 separately, thereby improving the assembly efficiency of the evaporator 32 and the fan 33 on the refrigerator 100. When the refrigerator 100 is configured as a vehicle refrigerator 100, it can adapt to the installation operation in the narrow space inside the vehicle refrigerator 100.

[0040] The air duct shell 20 may include a shell 21 and a cover 22. The cover 22 may be connected to the housing 10. A first air vent 201 and a second air vent 202 may be provided on the cover 22. The first air vent 201 and the second air vent 202 may be connected to the storage chamber respectively. One of the first air vent 201 and the second air vent 202 is used for the air duct shell 20 to discharge air into the storage chamber, and the other is used for the air duct shell 20 to draw air into the storage chamber, so that the air in the storage chamber and the air duct shell 20 maintains a circulating flow. When the heat exchange component 30 is actually installed, it may be installed with the cover 22, or it may be installed with the shell 21, or it may be installed with both the cover 22 and the shell 21 at the same time. No specific limitation is made here.

[0041] The technical solution of this utility model sets up a bracket 31, through which the evaporator 32 and the fan 33 are installed to form a single heat exchange component 30. The heat exchange component 30 can be directly installed into the air duct shell 20, and then the air duct shell 20 is installed into the cabinet 10, so that the overall assembly of the heat exchange component 30 can be completed without the need to install the fan 33 and the evaporator 32 separately. When the refrigerator 100 is configured as a vehicle refrigerator 100, it can adapt to the installation operation in the narrow space inside the vehicle refrigerator 100, and improve the ease of assembly of the evaporator 32 and the fan 33 on the vehicle refrigerator 100.

[0042] See Figure 3 , Figure 4 As shown, in one embodiment, the bracket 31 includes a bracket body 311, the evaporator 32 and the fan 33 are disposed on opposite sides of the bracket body 311, and the bracket body 311 has an air outlet 301, which is disposed between the evaporator 32 and the fan 33.

[0043] This configuration allows for the separate installation of the evaporator 32 and the fan 33 by providing mounting feet on opposite sides of the bracket body 311. This method is simpler than installing the evaporator 32 and the fan 33 on the same side of the bracket body 311. Furthermore, when the evaporator 32 and the fan 33 are located on opposite sides of the bracket body 311, an air outlet 301 can be provided on the bracket body 311 to facilitate airflow between the evaporator 32 and the fan 33, allowing for airflow between them.

[0044] Optionally, the bracket 31 further includes a first mounting portion 31a disposed on the bracket body 311, and the evaporator 32 is provided with a first mounting mating portion 32a that is fixedly engaged with the first mounting portion 31a.

[0045] The first mounting part 31a can be configured as a snap-fit ​​protrusion, which is located on the side of the bracket body 311 where the evaporator 32 is mounted. The first mounting mating part 32a can be configured as a snap-fit ​​groove located on the outer periphery of the evaporator 32. The evaporator 32 is snap-fitted onto the bracket body 311 by the snap-fit ​​engagement of the snap-fit ​​protrusion and the snap-fit ​​groove. Alternatively, the first mounting part 31a can be configured as a first mounting post 312, which can be provided with a first mounting hole 312a. The first mounting mating part 32a can be configured as a second mounting hole on the evaporator 32. The second mounting hole can be a hole originally reserved on the evaporator 32 for mounting and fixing the evaporator 32. When the evaporator 32 is mounted onto the bracket 31, the second mounting hole can be aligned with the first mounting hole 312a on the first mounting post 312. The evaporator 32 is mounted and fixed to the bracket 31 by inserting a screw into the second mounting hole and screwing it into the first mounting hole 312a.

[0046] To ensure that the existing mounting holes on evaporator 32 continue to serve their installation purpose, please refer to... Figure 3 , Figure 4 As shown, optionally, the first mounting part 31a is configured as a plurality of first mounting posts 312, the plurality of first mounting posts 312 are spaced apart along the periphery of the bracket body 311, the first mounting posts 312 are provided with first mounting holes 312a, and the first mounting mating part 32a is configured as a plurality of second mounting holes, the plurality of first mounting holes 312a and the plurality of second mounting holes are arranged opposite to each other.

[0047] The second mounting hole can be a pre-reserved mounting hole for the evaporator 32. The positions of the multiple first mounting posts 312 on the bracket body 311 can be arranged according to the positions of the pre-reserved mounting holes for the evaporator 32. This eliminates the need for additional mounting structures on the evaporator 32, improving its installation versatility and facilitating the installation of different models of evaporators 32. When setting the first mounting posts 312, they can protrude from the side of the bracket body 311 facing the evaporator 32. This allows for a certain gap between the evaporator 32 and the bracket body 311 when the evaporator 32 is installed on the bracket 311, facilitating air circulation near the bracket body 311 and promoting heat exchange.

[0048] Optionally, the bracket 31 further includes a second mounting portion 31b disposed on the bracket body 311, and the fan 33 is provided with a second mounting mating portion 33a that is fixedly engaged with the second mounting portion 31b.

[0049] Similar to the first mounting part 31a and the first mounting mating part 32a, the second mounting part 31b can be configured as a slot, and the second mounting mating part 33a can be configured as a protrusion. The fan 33 can be installed on the bracket body 311 by the snap-fit ​​of the slot and the protrusion. Alternatively, the second mounting part 31b can be configured as a second mounting post 313. The second mounting post 313 is provided with a third mounting hole 313a, and the second mounting mating part 33a is configured as a fourth mounting hole. The fourth mounting hole can be the original mounting hole reserved for the fan 33. When the fan 33 is installed on the bracket 31, the fourth mounting hole is aligned with the third mounting hole 313a. The fan 33 can be installed on the bracket 31 by passing a screw through the fourth mounting hole and screwing it into the third mounting hole 313a.

[0050] Similar to the installation of evaporator 32, to ensure that the pre-drilled mounting holes on fan 33 are functional, please refer to [link / reference needed]. Figure 3 , Figure 4As shown, optionally, the second mounting part 31b is configured as a plurality of second mounting posts 313, the plurality of second mounting posts 313 are spaced apart along the periphery of the bracket body 311, the second mounting posts 313 are provided with third mounting holes 313a, and the second mounting mating part 33a is configured as a plurality of fourth mounting holes, the plurality of fourth mounting holes and the plurality of third mounting holes 313a are arranged opposite to each other.

[0051] The fourth mounting hole can be the original mounting hole used for fixing the fan 33. The positions of the multiple second mounting posts 313 on the bracket body 311 can be set according to the arrangement of the multiple fourth mounting holes. In this way, only the second mounting part 31b needs to be set to realize the installation of the fan 33 on the bracket 31, thereby improving the versatility of the fan 33 on the bracket 31 and facilitating the installation of fans 33 with different configurations. Furthermore, when setting the second mounting posts 313, the second mounting posts 313 can be protruding on the side of the bracket body 311 facing the fan 33. In this way, when the fan 33 is installed on the bracket 31, a certain gap can be reserved between the fan 33 and the bracket body 311 to facilitate the airflow near the fan 33 and the air duct shell 20.

[0052] Optionally, the bracket 31 further includes a third mounting portion 31c disposed on the bracket body 311, and the air duct shell 20 is provided with a third mounting mating portion 20a that is fixedly engaged with the third mounting portion 31c.

[0053] It is understood that when the duct housing 20 includes a housing 21 and a cover 22, the third mounting mating part 20a can be provided on the housing 21, or on the cover 22, or both the housing 21 and the cover 22 can have the third mounting mating part 20a provided; no specific limitation is made here. The third mounting part 31c can be configured as a snap-fit, and the third mounting mating part 20a can be configured as a slot. The snap-fit ​​and slot engage to achieve the snap-fit ​​installation of the bracket 31 within the duct housing 20. Since the evaporator 32 and the fan 33 are both mounted on the bracket 31, the bracket 31 needs to withstand the eccentric force of the fan 33's rotation, as well as the weight of the evaporator 32, the fan 33, and the bracket 31 itself. To improve the installation stability of the bracket 31 on the duct housing 20, it can be installed inside the duct housing 20 using screws.

[0054] See Figure 3 , Figure 4As shown, optionally, the third mounting part 31c is configured as a plurality of mounting protrusions 315, which are located on the periphery of the bracket body 311. The mounting protrusions 315 have a fifth mounting hole 315a. The third mounting mating part 20a is configured as a third mounting post 211, which has a sixth mounting hole 211a. The fifth mounting hole 315a and the sixth mounting hole 211a are arranged opposite to each other.

[0055] In this utility model, since both the evaporator 32 and the fan 33 have a certain thickness, when the evaporator 32 is assembled to the bracket 31, there is a certain distance between the side of the bracket 31 where the evaporator 32 is located and the inner wall of the air duct shell 20, and there is also a certain distance between the side of the bracket 31 where the fan 33 is located and the inner wall of the air duct shell 20. Therefore, a third mounting post 211 can be protruded from the inner wall of the air duct shell 20, so that the third mounting post 211 is closer to the mounting protrusion 315 on the bracket body 311, thereby facilitating the screw to pass through the fifth mounting hole 315a on the mounting protrusion 315 and screw it into the sixth mounting hole 211a of the third mounting post 211, thus realizing the installation of the bracket 31 and the inner wall of the air duct shell 20.

[0056] Continue reading Figure 3 , Figure 4 As shown, in one embodiment, the bracket 31 further includes a plurality of ribs 314, which are disposed on the periphery of the bracket body 311 and extend toward the side of the bracket body 311 closer to the evaporator 32. Each rib 314 has a mounting protrusion 315 at one end away from the bracket body 311.

[0057] Understandably, since the thickness of the evaporator 32 is greater than that of the fan 33, when the bracket 31 is installed from the side closest to the evaporator 32 to the inner wall of the duct shell 20, to avoid insufficient strength due to the excessive length of the third mounting post 211 caused by the greater thickness of the evaporator 32, this invention provides a rib 314 on the side of the bracket body 311 facing the evaporator 32, and positions the mounting protrusion 315 on the side of the rib 314 away from the bracket body 311. This makes the distance between the mounting protrusion 315 and the inner wall of the duct shell 20 closer, thus eliminating the need for an excessively long third mounting post 211 and ensuring its structural strength. Furthermore, when multiple ribs 314 are provided around the perimeter of the bracket body 311, they can enclose and form an accommodating space for the evaporator 32, and also provide support for the evaporator 32, thereby improving the installation stability of the evaporator 32 on the bracket 31.

[0058] Optionally, the air duct shell 20 includes a shell 21 and a cover 22, with the cover 22 located between the shell 21 and the housing 10. Thus, by setting the air duct shell 20 as two separate parts, it is convenient to install the heat exchange assembly 30 inside the air duct shell 20.

[0059] Furthermore, when the duct housing 20 includes a housing 21 and a cover 22, the third mounting post 211 can be installed on the housing 21, and the heat exchange assembly 30 can be installed and fixed to the housing 21 through the fifth mounting hole 315a of the bracket 31. Alternatively, the third mounting post 211 can be installed on the cover 22, and the heat exchange assembly 30 can be installed and fixed to the cover 22 through the fifth mounting hole 315a of the bracket 31. Or, the third mounting post 211 can be installed on both the housing 21 and the cover 22, and the heat exchange assembly 30 can be installed and fixed to both the housing 21 and the cover 22 through the fifth mounting hole 315a of the bracket 31, thereby increasing the installation firmness of the heat exchange assembly 30. Optionally, the third mounting post 211 is installed on the housing 21; and / or, the third mounting post 211 is installed on the cover 22.

[0060] Optionally, the cover 22 is provided with a first air vent 201 and a second air vent 202, which communicate with the storage compartment. The fan 33 is disposed opposite to the first air vent 201. One of the first air vent 201 and the second air vent 202 is an air outlet that supplies air into the storage compartment, and the other is an air inlet that draws air into the duct shell 20. The first air vent 201 can be located above the second air vent 202. It is understood that, due to the lower density of hot air, the first air vent 201 can be set as the air inlet of the duct shell 20 to introduce hot air with a higher temperature from the upper part of the storage compartment into the duct shell 20. After heat exchange by the evaporator 32, cold air is formed and enters the storage compartment from the second air vent 201, making the cold air distribution inside the storage compartment more uniform when the refrigerator 100 is cooling. Of course, in other embodiments, the first air vent 201 can also be set as the air outlet of the duct shell 20; this is not limited here.

[0061] Optionally, the heat exchange assembly 30 has wiring terminals for electrically connecting the evaporator 32 and the fan 33 to the housing 10. These terminals can be plug-in terminals capable of energizing the evaporator 32 and the fan 33. This allows the fan 33 and evaporator 32 to not only be installed on the inner wall of the duct housing 20 and installed together with the duct housing 20 into the housing 10, enabling simultaneous installation of the temperature sensor 33 and the evaporator 32, but also to combine the individual wiring terminals of the fan 33 and the evaporator 32 within the duct housing 20 into a single terminal block. This terminal block can then be plugged into the sockets of the circuit components within the housing 10, allowing simultaneous wiring of the fan 33 and the evaporator 32. This improves the portability of wiring the fan 33 and the evaporator 32, enhancing the wiring experience within the confined space of the vehicle refrigerator 100.

[0062] This utility model also proposes a vehicle, which includes a vehicle body and a refrigerator. The specific structure of the refrigerator 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.
