[0043] Currently, the traditional installation method for household air-cooled refrigerators is to install the evaporator on the cabinet and place the temperature sensor on the air duct cover. Both the evaporator and the temperature sensor have plug-in terminals, which are plugged into the sockets of the circuit components inside the cabinet. When a traditional air-cooled refrigerator is set up as a vehicle-mounted air-cooled refrigerator, the temperature sensor is inconvenient to install and the terminals are difficult to plug in due to the small internal space of the vehicle refrigerator.

[0044] This utility model proposes a refrigerator 100 that improves the ease of installation of the temperature measuring element 33 in the confined space inside a vehicle refrigerator.

[0045] Please see Figures 1 to 5 In one embodiment of this utility model, the refrigerator 100 includes a cabinet 10, an air duct shell 20, a heat exchange component 30, and a fan 40. The cabinet 10 has a storage compartment. The air duct shell 20 is installed in the cabinet 10 and communicates with the cabinet 10. The heat exchange component 30 is disposed inside the air duct shell 20 and is provided with a temperature measuring element 33. The fan 40 is disposed inside the air duct shell 10 and is used to send the air inside the air duct shell 20 through the evaporator 32 and into the storage compartment.

[0046] In this utility model, the refrigerator 100 can be configured as a vehicle refrigerator 100, and the storage compartment of the cabinet 10 can be used as a container for storing food in the refrigerator 100. The air duct shell 20 can include a shell 21 and a cover 22. The cover 22 can be connected to the cabinet 10. The heat exchange assembly 30 can include an evaporator 32 and a bracket 31 for mounting the evaporator 32. The evaporator 32 and the fan 40 can be set on the same side of the bracket 31 or on opposite sides of the bracket 31. The fan 40 can be mounted on the bracket 31 or on the inner wall of the air duct shell 20, as long as the fan 40 is directed toward the evaporator 32. The fan 40 can be configured as an axial flow fan, with the fan 40 facing the evaporator 32. The air inlet of the fan 40 can face the evaporator 32, or the air outlet of the fan 40 can face the evaporator 32. Since the air duct shell 20 is connected to the storage compartment, when the fan 40 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 evaporates and absorbs heat, the heat in the storage compartment can be carried away by the flowing air, thereby realizing the air-cooling function of the refrigerator 100.

[0047] The temperature measuring element 33 can be configured as a temperature sensing probe. The temperature measuring element 33 is located on the heat exchange component 30, or it can be located on the bracket 31 of the heat exchange component 30. The temperature measuring element 33 can be positioned close to the air outlet of the air duct shell 20. The temperature measuring element 33 can be snapped onto the bracket 31, so that after the temperature measuring element 33 is installed, it can be close to the air outlet of the air duct shell 20, thus not affecting the temperature measuring operation of the temperature measuring element 33.

[0048] Since the temperature sensor 33 can be pre-installed on the heat exchange assembly 30, it can be conveniently shared with the heat exchange assembly 30 using a single terminal. When the heat exchange assembly 30 includes an evaporator 32, it can be connected to the socket of the circuit components inside the housing 10 using a single terminal. Furthermore, when both the evaporator 32 and the temperature sensor 33 are mounted on the bracket 31, it is only necessary to install the component inside the duct housing 20, then install the fan 40 on the inner wall of the duct housing 20 or on the bracket 31, and finally install the duct housing 20 on the housing 10 to complete the overall assembly. There is no need to install the evaporator 32 and the temperature sensor 33 separately, or to wire the temperature sensor 33 separately, thereby improving the assembly efficiency of the evaporator 32 and the temperature sensor 33 inside 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.

[0049] The technical solution of this utility model is to set the temperature measuring element 33 in the heat exchange component 30, so that the temperature measuring element 33 can be installed in the air duct shell 20 together with the heat exchange component 30. When the heat exchange component 30 includes an evaporator 32, it can be installed together with the evaporator 32. When the refrigerator 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 assembly convenience of the internal components of the refrigerator 100.

[0050] See Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment, the heat exchange assembly 30 includes a bracket 31, the bracket 31 includes a bracket body 311 and a temperature measuring element mounting portion 316 disposed on the bracket body 311, the temperature measuring element mounting portion 316 having a mounting groove for inserting the temperature measuring element 33.

[0051] In the above embodiments, the bracket 31 can serve as a mounting frame for each component in the heat exchange assembly 30, allowing for pre-installation of each component. By providing a separate temperature sensor mounting section 316 on the bracket body 311, and installing the temperature sensor 33 through the mounting groove of the temperature sensor mounting section 316, independent installation of the temperature sensor 33 on the bracket 31 can be achieved. Furthermore, the evaporator 32 and the fan 40 are positioned on opposite sides of the bracket body 311, allowing for separate installation of the evaporator 32 and fan 40 by providing mounting feet on opposite sides of the bracket body 311. This installation method is simpler than installing the evaporator 32 and fan 40 on the same side of the bracket body 311. Moreover, when the evaporator 32 and fan 40 are positioned 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 40, allowing air to flow between them.

[0052] The structure of the temperature measuring element mounting section 316 will be further described below. (See reference...) Figure 4 , Figure 5As shown, in one embodiment, the temperature measuring element mounting portion 316 includes a base 316a and a first rib 316b and a second rib 316c disposed on the base 316a. The first rib 316b and the second rib 316c are disposed opposite to each other to form the mounting groove. The first rib 316b and the second rib 316c can be elastic ribs. When the temperature measuring element 33 is installed into the mounting groove formed by the first rib 316b and the second rib 316c, the temperature measuring element 33 can elastically abut against the first rib 316b and the second rib 316c, thereby limiting the temperature measuring element 33 in the mounting groove and realizing the installation of the temperature measuring element 33 on the bracket 31. The first rib 316b and the second rib 316c can be set as one set, or multiple sets of the first rib 316b and the second rib 316c can be set. Multiple sets of the first rib 316b and the second rib 316c can be set at intervals along the length of the temperature measuring element 33, so that there can be multiple mounting slots. Multiple mounting slots can limit the installation of the temperature measuring element 33 at multiple positions respectively.

[0053] Additionally, two retaining protrusions can be provided at the ends of the first rib 316b and the second rib 316c away from the base 316a, respectively, to prevent the temperature measuring element 33 from falling out of the mounting groove. The relevant settings are as follows; optionally, refer to [reference needed]. Figure 5 As shown, the first rib 316b has a first locking protrusion 316d on the side away from the base 316a, and the second rib 316c has a second locking protrusion 316e on the side away from the base 316a. The first locking protrusion 316d and the second locking protrusion 316e extend towards each other to limit the side of the temperature measuring element 33 away from the base, so that the diameter of the ruler at the outlet of the mounting groove is smaller than the diameter inside the mounting groove. When the temperature measuring element 33 is limited and installed in the mounting groove, it can prevent the temperature measuring element 33 from falling off the outlet of the mounting groove.

[0054] When installing and fixing the temperature measuring element 33 through the mounting slot, to prevent the base 316a from interfering with the air flowing through the temperature measuring element 33, thus preventing the air from effectively flowing through the temperature measuring element 33 and causing the temperature measuring element 33 to fail to effectively measure the temperature, please refer to the following: Figure 5 As shown, optionally, the base 316a has a vent 316f, which connects to the mounting groove. The vent 316f can be located between the evaporator 32 and the fan 40, thus effectively guiding the air flowing between the fan 40 and the evaporator 32, allowing it to flow into the mounting groove from the vent 316f and then out of the opening of the mounting groove. This allows the heat exchange airflow to pass through the temperature sensing element 33, facilitating accurate temperature detection by the temperature sensing element 33.

[0055] See Figure 1 , Figure 2As shown, in one embodiment, the fan 40 is mounted on the bracket 311, and the heat exchange assembly 30 further includes an evaporator 32. ， The fan 40 and the evaporator 32 are located on opposite sides of the support body 311;

[0056] The air duct shell 20 is provided with a first air vent 201 and a second air vent 202 that connect to the storage room, and the fan 40 is arranged opposite to the first air vent 201.

[0057] In this way, the fan 40, evaporator 32, and temperature sensor 33 can be pre-installed on the bracket 31 to form a single heat exchange component 30. This allows the fan 40 to be connected to the circuit components inside the housing 10 by using a single terminal block, along with the evaporator 32 and temperature sensor 33. Furthermore, the entire assembly can be completed simply by installing the heat exchange component 30 inside the duct housing 20 and wiring it, and then installing the duct housing 20 onto the housing 10. This also improves the portability of the fan 40. When the refrigerator 100 is configured as a vehicle refrigerator 100, the installation and operation experience in the confined space inside the vehicle refrigerator 100 can be further enhanced.

[0058] In this refrigerator, one of the first air vent 201 and the second air vent 202 is an air outlet that supplies air to the storage compartment, and the other is an air inlet that draws air into the duct housing 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 housing 20 to introduce the hot air, which is at a higher temperature above the storage compartment, into the duct housing 20. After heat exchange in the evaporator 32, the resulting cold air enters the storage compartment through the second air vent 201, making the cold air distribution inside the storage compartment more uniform during refrigerator cooling. Of course, in other embodiments, the first air vent 201 can also be set as the air outlet of the duct housing 20; this is not a limitation.

[0059] When the first air vent 201 is set as the air inlet of the duct shell 20, optionally, the first air vent 201 is used for air intake of the duct shell 20, and the second air vent 202 is used for air outlet of the duct shell 20. The temperature measuring element 33 is positioned close to the second air vent 202. In this utility model, since the main function of the temperature measuring element 33 is to monitor the internal temperature of the refrigerator 100 in real time and transmit the data to the control system so that the refrigerator 100 can automatically adjust the working state of the refrigeration system to maintain the set temperature, placing the temperature measuring element 33 near the second air vent 202 facilitates the monitoring of the ambient temperature inside the storage compartment, thereby helping to more accurately control the internal temperature of the storage compartment and ensure the refrigeration effect of the refrigerator 100.

[0060] To allow the temperature sensor 33 to be positioned close to the second air outlet 202, the temperature sensor mounting portion 316 may optionally extend from the bracket body 311 toward the second air outlet 202. Thus, when the temperature sensor 33 is installed in the temperature sensor mounting portion 316, the temperature sensor 33 is positioned close to the second air outlet 202, making it easier for the temperature sensor 33 to accurately monitor the temperature inside the storage room.

[0061] Of course, in other embodiments, the first air vent 201 can also be used for air outlet of the air duct shell 20, and the second air vent 202 can also be used for air inlet of the air duct shell 20. In this case, the temperature measuring element mounting part 316 can extend from the bracket body 311 toward the first air vent 201, and the temperature measuring element 33 can be set close to the first air vent 201. No specific limitation is made here.

[0062] 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. 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.

[0063] 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, each of the first mounting posts 312 is provided with a first mounting hole 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.

[0064] 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.

[0065] Optionally, the bracket 31 further includes a second mounting portion 31b disposed on the bracket body 311, and the fan 40 is provided with a second mounting mating portion 40a that is fixedly engaged with the second mounting portion 31b.

[0066] 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 40a can be configured as a protrusion. The fan 40 is 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, which is provided with a third mounting hole 313a. The second mounting mating part 40a is configured as a fourth mounting hole, which can be the original mounting hole reserved for the fan 40. When the fan 40 is installed on the bracket 31, the fourth mounting hole is aligned with the third mounting hole 313a. The fan 40 is installed on the bracket 31 by passing a screw through the fourth mounting hole and screwing it into the third mounting hole 313a.

[0067] Similar to the installation of evaporator 32, to ensure that the pre-drilled mounting holes on fan 40 are functional, please refer to [link / reference needed]. Figure 3 , Figure 4 As 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 40a 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.

[0068] The fourth mounting hole can be the original mounting hole used for fixing the fan 40. 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 40 on the bracket 31, thereby improving the versatility of the fan 40 on the bracket 31 and facilitating the installation of the fan 40 in 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 40. In this way, when the fan 40 is installed on the bracket 31, a certain gap can be reserved between the fan 40 and the bracket body 311 to facilitate the airflow near the fan 40 and the air duct shell 20.

[0069] 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.

[0070] 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 both the evaporator 32 and the fan 40 are mounted on the bracket 31, the bracket 31 needs to withstand the eccentric force of the fan 40's rotation, as well as the weight of the evaporator 32, the fan 40, 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.

[0071] See Figure 3 , Figure 4 As 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.

[0072] In this utility model, since both the evaporator 32 and the fan 40 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 40 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.

[0073] 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.

[0074] Understandably, since the thickness of the evaporator 32 is greater than that of the fan 40, 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 periphery 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. In addition, when setting the first rib 316b and the second rib 316c of the temperature measuring element mounting part 316, one of the first rib 316b and the second rib 316c can be formed by one of the protruding ribs 314, thereby saving the setting material of the temperature measuring element mounting part 316 and simplifying the structure of the temperature measuring element mounting part 316.

[0075] See Figure 2 , Figure 3 As shown, in one embodiment, the duct housing 20 includes a housing 21 and a cover 22, with the cover 22 located between the housing 21 and the enclosure 10. 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.

[0076] 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.

[0077] Optionally, the heat exchange assembly 30 has a wiring terminal; the wiring terminal is used to electrically connect the temperature measuring element 33 and the evaporator 32 to the housing 10. This arrangement allows the temperature measuring element 33 and the evaporator 32 to be installed on the housing 10 via the bracket 31 and the air duct housing 20, enabling simultaneous installation of the temperature measuring element 33 and the evaporator 32. Furthermore, the wiring terminals of the temperature measuring element 33 and the evaporator 32 can be connected to the connecting wires on the bracket 31, and then combined into a single wiring terminal for plugging into the sockets of the circuit components inside the housing 10. This allows for simultaneous wiring of the temperature measuring element 33 and the evaporator 33, thereby improving the portability of the temperature measuring element 33 and facilitating wiring of the evaporator 32 and the temperature measuring element 33 in the confined space inside the vehicle refrigerator 100.

[0078] Furthermore, since the fan 40 is also mounted on the bracket 31, it can be installed in the housing 10 along with the air duct housing 20. Therefore, the fan 40, evaporator 32, and temperature sensor 33 can share the same terminal block for connection to the sockets of the circuit components inside the housing 10. This allows for simultaneous wiring of the temperature sensor 33, evaporator 33, and fan 40, further facilitating the installation experience of the vehicle refrigerator. Optionally, the terminal block is used to electrically connect the temperature sensor 33, evaporator 32, and fan 40 to the housing 10.

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.
