[0035] Currently, in household air-cooled refrigerators, due to the ample internal space, the traditional installation method involves mounting the evaporator on the refrigerator body and the fan on the duct cover, which is then installed onto the refrigerator body. The evaporator and fan need to be installed sequentially onto the refrigerator body. However, when a traditional air-cooled refrigerator is set up as a vehicle-mounted air-cooled refrigerator, the limited internal space of the vehicle refrigerator body and insufficient space for installation and operation lead to inconvenience in installing and operating the evaporator and fan.

[0036] This utility model proposes a refrigerator 100 that can improve the ease of installation of the evaporator 31 and the fan 32 in the small space inside the vehicle refrigerator 100.

[0037] Please see Figures 1 to 6In one embodiment of this utility model, the refrigerator 100 includes a cabinet 10, an air duct shell 20, and a heat exchange assembly 30; the cabinet 10 is provided with a storage compartment, the air duct shell 20 is installed on the cabinet 10 and communicates with the cabinet 10, the inner wall of the air duct shell 20 forms an installation portion 40, the heat exchange assembly 30 is disposed inside the air duct shell 20 and is used to be installed on the cabinet 10 along with the air duct shell 20, the heat exchange assembly 30 includes an evaporator 31 and a fan 32, the evaporator 31 and the fan 32 are respectively installed on the installation portion 40, and the fan 32 is used to allow air in the air duct shell 20 to pass through the evaporator 31 and be sent into the storage compartment.

[0038] In this invention, the refrigerator 100 can be configured as a vehicle-mounted refrigerator 100, and the storage compartment of the cabinet 10 can serve as a container for storing food. The positions of the evaporator 31 and the fan 32 on the inner wall of the air duct housing 20 are not limited, as long as the fan 32 faces the evaporator 31. The fan 32 can be an axial flow fan, and its orientation towards the evaporator 31 can be either with the air inlet or outlet facing the evaporator 31. Since the air duct housing 20 connects to the storage compartment, when the fan 32 faces the evaporator 31, it guides the airflow inside the air duct housing 20 through the evaporator 31 and into the storage compartment. When the evaporator 31 absorbs heat through evaporation, the flowing air carries away the heat from the storage compartment, thus achieving the air-cooling function of the refrigerator 100.

[0039] The mounting part 40 is formed on the inner wall of the air duct shell 20. The mounting part 40 can be integrally formed with the air duct shell 20. Alternatively, in other embodiments, the mounting part 40 can be fixed to the air duct shell 20 by fasteners. The air duct shell 20 may include a shell 21 and a shell cover 22. The mounting part 40 may be disposed on the inner wall of the shell 21 or on the inner wall of the shell cover 22. When the mounting part 40 is disposed on the inner wall of the shell 21, the evaporator 31 and the fan 32 are mounted on the shell 21. When the mounting part 40 is disposed on the inner wall of the shell 21, the evaporator 31 and the fan 32 are mounted on the shell cover 22.

[0040] In actual installation, whether the evaporator 31 and the fan 32 are installed on the housing 21 or the housing cover 22 via the mounting part 40, they can be pre-installed via the mounting part 40 to form the heat exchange assembly 30 connected to the air duct housing 20. When the air duct housing 20 is subsequently installed with the cabinet 10, it can be installed along with the air duct housing 20 to the cabinet 10, thus completing the installation of the evaporator 31 and the fan 32. There is no need to install the evaporator 31 and the fan 32 separately to the cabinet 10. 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.

[0041] The technical solution of this utility model is to form an installation part 40 in the air duct shell 20, and install the evaporator 31 and the fan 32 in the installation part 40 to form a single heat exchange component 30. It can be installed together with the air duct shell 20 into the cabinet 10 to complete the assembly of the heat exchange component 30 in the cabinet 10. It is not necessary to install the evaporator 31 and the fan 32 into the cabinet 10 in sequence. 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 31 and the fan 32 in the vehicle refrigerator 100.

[0042] See Figure 3 , Figure 5 As shown, in one embodiment, the mounting portion 40 includes a first sub-mounting portion 41, which includes a first latching protrusion 411 and a second latching protrusion 412 disposed opposite to each other. The first latching protrusion 411, the inner wall of the air duct shell 20, and the second latching protrusion 412 cooperate to latch and mount the fan 32.

[0043] The first locking protrusion 411 and the second locking protrusion 412 are arranged opposite to each other. The first locking protrusion 411 may have a first arm, and the second locking protrusion 412 may have a second arm. The first arm and the second arm are arranged opposite to each other. After the fan 32 is installed, the first arm and the second arm can limit the periphery of the fan 32. When the first arm and the second arm limit the periphery of the fan 32, the first arm and the second arm can respectively abut against the left and right sides of the fan 32, or the first arm and the second arm can respectively abut against the fan 32. The upper and lower sides of 2 abut against each other; the first locking protrusion 411 may also have a third arm that is disposed opposite to the inner wall of the air duct shell 20, and the second locking protrusion 412 may also have a fourth arm that is disposed opposite to the inner wall of the air duct shell 20. After the fan 32 is installed, the third arm and the fourth arm can limit the front side of the fan 32, and the inner wall of the air duct shell 20 can limit the rear side of the fan 32, so that the periphery and the front and rear sides of the fan 32 can be effectively limited, thereby allowing the fan 32 to be installed on the first sub-mounting part 41.

[0044] Since the fan 32 will experience circumferential deflection force during operation, to improve the installation and fixation effect of the fan 32 and prevent the fan 32 from being unstable due to deflection force, optionally, please refer to [further details needed]. Figure 3 , Figure 5 The first sub-installation part 41 further includes a limiting frame 413 disposed on the inner wall of the air duct shell 20. The limiting frame 413 has two oppositely arranged first side walls 413a and two oppositely arranged second side walls 413b. The two first side walls 413a and the two second side walls 413b enclose a limiting space 401, and the fan 32 is disposed in the limiting space 401.

[0045] In the above embodiments, the first sidewall 413a may be connected to the adjacent second sidewall 413b, or it may not be connected to the adjacent second sidewall 413b. The two first sidewalls 413a may be the left and right sidewalls of the limiting frame 413 to limit the fan 32 left and right, and the two second sidewalls 413b may be the upper and lower sidewalls of the limiting frame 413 to limit the fan 32 up and down. This ensures that the fan 32 can be effectively limited in all four directions (up, down, left, and right). When the fan 32 generates a deflection force distributed along its circumference during operation, the fan 32 will not deflect because it is limited in all directions, and can remain on the mounting part 40, thereby ensuring the installation stability of the fan 32. Of course, in other embodiments, the two first sidewalls 413a may also be the upper and lower sidewalls of the limiting frame 413, and the two second sidewalls 413b may also be the left and right sidewalls of the limiting frame 413. No specific limitation is made here.

[0046] Optionally, when the first latching protrusion 411 and the second latching protrusion 412 are actually installed, the first latching protrusion 411 and the second latching protrusion 412 are respectively provided on the two first sidewalls 413a. The first arm of the first latching protrusion 411 can be the inner wall of one of the first sidewalls 413a, the second arm of the second latching protrusion 412 can be the inner wall of the other first sidewall 413a, the third arm of the first latching protrusion 411 can be a protrusion extending from the inner wall of one of the first sidewalls 413a toward the other first sidewall 413a, and the fourth arm of the second latching protrusion 412 can be a protrusion extending from the inner wall of the other first sidewall 413a toward the first sidewall 413a. The two protrusions can abut against the front side of the fan 32, and the inner wall of the duct shell 20 can abut against the rear side of the fan 32, thereby realizing the limiting installation of the fan 32. Alternatively, the first latching protrusion 411 and the second latching protrusion 412 are respectively provided on the two second side walls 413b, which can limit the upper and lower movement of the fan 32, and cooperate with the inner wall of the air duct shell 20 to limit the front and rear movement of the fan 32. This is not limited here.

[0047] See Figure 5 As shown, optionally, the first protrusion 411 has a first limiting surface 4111, and the second protrusion 412 has a second limiting surface 4121. The first limiting surface 4111 and the second limiting surface 4121 face the inner wall of the air duct shell 20, and the fan 32 is limited and engaged with the first limiting surface 4111 and the second limiting surface 4121.

[0048] In the above embodiment, the first limiting surface 4111 can be disposed on the side of the first arm facing the duct shell 20, and the second limiting surface 4121 can be disposed on the side of the second arm facing the duct shell 20. When the fan 32 is limited and engaged with the first limiting surface 4111 and the second limiting surface 4121, the fan 32 can abut against the first limiting surface 4111 and the second limiting surface 4121. At this time, the first limiting surface 4111 and the second limiting surface 4121 can not only limit the fan 32 in the front and rear directions, but also allow for... The friction generated by the contact with the fan 32 provides circumferential limitation for the fan 32, thereby improving the installation limitation effect of the fan 32; alternatively, the first limiting surface 4111 and the second limiting surface 4121 may only contact the fan 32 without exerting a radial contact force on the fan 32. The first limiting surface 4111 and the second limiting surface 4121 may only cooperate with the inner wall of the duct shell 20 to limit the fan 32 front and rear. The circumferential limitation of the fan 32 is achieved through the limiting frame 413, thus realizing the limitation installation of the fan 32. Related settings are not limited here.

[0049] Since the first locking protrusion 411 and the second locking protrusion 412 are set on the limiting frame 413, the first arm of the first locking protrusion 411 and the second arm of the second locking protrusion 412 extend towards each other to limit the front and rear of the fan 32. In order to avoid the setting of the first locking protrusion 411 and the second locking protrusion 412 from affecting the fan 32 being installed in the limiting space 401, optionally, the first locking protrusion 411 also has a guide surface 4112. The guide surface 4112 is used to guide the fan 32 to move to the first limiting surface 4111. The guide surface 4112 has a first end 4112a away from the limiting space 401 and a second end 4112b close to the limiting space 401. The guide surface 4112 is inclined from the first end 4112a to the second end 4112b.

[0050] In this way, one side of the fan 32 can be inserted between the second latching protrusion 412 and the inner wall of the duct shell 20. Then, the other side of the fan 32 can be slid along the guide surface 4112 from the first end 4112a of the guide surface 4112 to the second end 4112b of the guide surface 4112, and then inserted from the second end 4112b into the space between the first limiting surface 4111 and the inner wall of the duct shell 20, so that both sides of the duct shell 20 are effectively engaged and accommodated in the limiting space 401, thereby realizing the installation of the fan 32.

[0051] Optionally, the mounting portion 40 further includes a second sub-mounting portion, and the evaporator 31 has a sub-mounting mating portion that mounts and mates with the second sub-mounting portion.

[0052] The second sub-mounting part can be configured as a snap-fit ​​protrusion, which is located on the periphery of the first sub-mounting part 41. The sub-mounting mating part can be configured as a snap-fit ​​groove located on the outer periphery of the evaporator 31. The snap-fit ​​mating of the snap-fit ​​protrusion and the snap-fit ​​groove enables the evaporator 31 to be snap-fitted onto the inner wall of the air duct shell 20. Alternatively, the second sub-mounting part can be configured as multiple first mounting posts 42, which are located on the outer periphery of the first sub-mounting part 41. Each first mounting post 42 can be provided with a first mounting hole 421. The sub-mounting mating part can be configured with a second mounting hole 311 on the evaporator 31. The second mounting hole 311 can be a hole originally reserved on the evaporator 31 for mounting and fixing the evaporator 31. When the evaporator 31 is installed onto the inner wall of the air duct shell 20, the second mounting hole 311 can be aligned with the first mounting hole 421 on the first mounting post 42. The evaporator 31 is installed and fixed onto the inner wall of the air duct shell 20 by inserting a screw into the second mounting hole 311 and screwing it into the first mounting hole 421.

[0053] To ensure that the existing mounting holes on evaporator 31 continue to serve their installation purpose, please refer to... Figure 4 , Figure 5 As shown, optionally, the second sub-mounting part is configured as a plurality of first mounting posts 42, the plurality of first mounting posts 42 are disposed on the periphery of the first sub-mounting part 41, each of the first mounting posts 42 is provided with a first mounting hole 421, and the sub-mounting mating part is configured as a plurality of second mounting holes 311, the plurality of second mounting holes 311 being arranged opposite to the plurality of first mounting holes 421 one by one.

[0054] The second mounting hole 311 can be a pre-reserved mounting hole for the evaporator 31. The positions of the multiple first mounting posts 42 on the inner wall of the duct housing 20 can be arranged according to the positions of the pre-reserved mounting holes on the evaporator 31. This eliminates the need for additional mounting structures on the evaporator 31, improving its installation versatility and facilitating the installation of different models of evaporators 31. When setting the first mounting posts 42, since they protrude from the inner wall of the duct housing 20 towards the evaporator 31, the evaporator 31 can avoid interference with the fan 32 when installed on the inner wall of the duct housing 20.

[0055] Optionally, the heat exchange assembly 30 has wiring terminals for electrically connecting the evaporator 31 and the fan 32 to the housing 10.

[0056] Among them, the power connection terminal can be a plug-in terminal that can connect the evaporator 31 and the fan 32. In this way, the fan 32 and the evaporator 31 can not only be installed on the inner wall of the air duct shell 20 and installed together with the air duct shell 20 into the cabinet 10, realizing the simultaneous installation of the temperature measuring element 33 and the evaporator 32, but also the wiring terminals of the fan 32 and the evaporator 31 can be combined in the air duct shell 20 to form a general wiring terminal, which can be plugged into the socket of the circuit component in the cabinet 10, so that the fan 32 and the evaporator 31 can be wired at the same time. This can improve the portability of wiring the fan 32 and the evaporator 31 and improve the wiring operation experience of the fan 32 and the evaporator 31 in the confined environment inside the vehicle refrigerator 100.

[0057] See Figure 2 , Figure 3 As shown, in one embodiment, the duct housing 20 includes a housing 21 and a cover 22. The cover 22 is disposed between the housing 21 and the box body 10, and the mounting portion 40 is disposed on the side of the cover 22 facing the housing 21. Thus, by configuring the duct housing 20 as two separate parts, the installation of the heat exchange assembly 30 within the duct housing 20 is facilitated. When the mounting portion 40 is disposed on the side of the cover 22 facing the housing 21, the heat exchange assembly 30 can be mounted on the cover 22. Since the cover 22 is closer to the box body 10 than the housing 21, when a vent is opened on the cover 22 communicating with the storage compartment of the box body 10, heat exchange between the heat exchange assembly 30 and the interior of the box body 10 is facilitated.

[0058] The cover 22 is provided with a first air vent 201 and a second air vent 202, which are connected to the storage compartment of the cabinet 10. The mounting part 40 is located on the periphery of 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 to the storage compartment of the cabinet 10, and the other is an air inlet that allows air to enter the air 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 air duct shell 20 to introduce the hot air with a higher temperature from the upper part of the storage compartment into the air duct shell 20. After heat exchange by the evaporator 31, cold air is formed and enters the storage compartment from the second air vent 202, making the cold air distribution inside the storage compartment more uniform when the refrigerator 100 is cooling. When the mounting part 40 is located around the first air outlet 201, the distance between the fan 32 and the first air outlet 201 is closer after the fan 32 is installed. When the first air outlet 201 is configured as the air inlet of the duct shell 20, the fan 32 has a greater suction force on the air in the storage room, allowing the fan 32 to better perform its air-guiding function, thereby making the heat exchange between the air in the storage room and the evaporator 31 more complete. Of course, in other embodiments, the first air outlet 201 can also be configured as the air outlet of the duct shell 20, which is not limited here.
