The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] On the one hand, such as Figures 1 to 8 As shown, this application embodiment provides an evaporator mounting structure, including a base 1 and a first mounting plate 2; the base 1 is provided with a mounting groove 11 for mounting an evaporator 4, the front side wall of the mounting groove 11 is provided with a first snap-fit ​​part 12, and the rear side wall of the mounting groove 11 is provided with a first insertion part 13; the first mounting plate 2 is snapped onto the end of the evaporator 4, and the opposite ends of the first mounting plate 2 are respectively provided with a second snap-fit ​​part 21 and a second insertion part 22, the second snap-fit ​​part 21 is used to snap onto the first snap-fit ​​part 12, and the first insertion part 13 and the second insertion part 22 are connected in cooperation.

[0033] In this embodiment, the first snap-fit ​​part 12 and the second snap-fit ​​part 21 located on the front side are snapped together first. The snap-fit ​​position is not blocked by other structural components, so the first mounting plate 2 can be accurately snapped into place during the installation of the evaporator 4. Then, the rear side of the first mounting plate 2 is inserted into the second insertion part 22 to complete the assembly of the evaporator 4. Compared with the prior art, this setting can ensure stable snap-fit ​​and reduce the occurrence of incomplete snap-fit, thereby improving the assembly efficiency of the evaporator 4.

[0034] In some embodiments, such as Figure 2 and Figure 5 As shown, the first insertion part 13 is a slot, and the second insertion part 22 is a pin. The pin protrudes from the first mounting plate 2 and can be movably inserted into the slot.

[0035] Specifically, one end of the first mounting plate 2 is first snapped in, and then a pin protruding from the first mounting plate 2 is inserted into a slot to fix the first mounting plate 2 onto the base 1, thereby fixing the evaporator 4. This snap-fit ​​connection method is convenient and quick, improving assembly efficiency. In some other embodiments, the second insertion part 22 is a slot, and the first insertion part 13 is a pin.

[0036] In some embodiments, such as Figure 2 and Figure 5 As shown, the first mounting plate 2 is provided with a sliding groove 23, and the second plug-in part 22 and the sliding groove 23 are arranged adjacent to each other. The first plug-in part 13 has a first side wall 14. When the second plug-in part 22 is inserted into the first plug-in part 13, the first side wall 14 of the slot is inserted into the sliding groove.

[0037] Specifically, when the pin and the slot are inserted into each other, the first sidewall 14 of the slot also inserts into the groove 23. The first sidewall 14 restricts the movement of the pin, and the groove 23 restricts the movement of the first sidewall 14. This arrangement enhances the mutual limiting effect between the first mounting plate 2 and the slot, ensuring that misalignment is prevented and further improving the installation stability of the first mounting plate 2. In some other embodiments, the end of the pin is provided with a blind hole, and the slot is provided with a plug-in post. When the pin is inserted into the slot, the plug-in post is adapted to insert into the blind hole.

[0038] In some embodiments, as Figure 2 and Figure 5 As shown, the first sidewall 14 is provided with a snap-fit ​​protrusion 15. When the first sidewall 14 is inserted into the slide groove 23, the snap-fit ​​protrusion 15 and the sidewall of the slide groove 23 abut and fix each other.

[0039] Specifically, the first sidewall 14 has a locking protrusion 15 on the side facing the pin. When the first sidewall 14 is inserted into the slide groove 23, the outer surface of the locking protrusion 15 abuts against the inner wall of the slide groove 23. This arrangement increases the friction between the locking protrusion 15 and the slide groove 23, thereby increasing the installation stability of the first mounting plate 2. In some other embodiments, multiple friction protrusions are provided on the inner wall of the slide groove 23, and the friction protrusions abut against the surface of the first sidewall 14.

[0040] In some embodiments, as Figure 2 and Figure 5 As shown, the first mounting plate 2 is also provided with a reinforcing rib 24 connected to the pin. The opposite two sides of the reinforcing rib 24 are respectively provided with a sliding groove 23. The slot is provided with a clearance opening 17, which divides the first side wall 14 into a left sub-wall 14a and a right sub-wall 14b that are spaced apart. When the pin is inserted into the slot, the reinforcing rib 24 is inserted into the clearance opening 17, and the left sub-wall 14a and the right sub-wall 14b are respectively inserted into the sliding grooves 23 located on opposite sides of the reinforcing rib 24.

[0041] Specifically, when the pin is inserted into the slot, the reinforcing rib 24 can be engaged in the clearance opening 17. The left sub-wall 14a and right sub-wall 14b on both sides of the clearance opening 17 are respectively inserted into the sliding grooves 23 on both sides of the reinforcing rib 24. The engaging protrusion 15 is also divided into two parts and is set on the left sub-wall 14a and right sub-wall 14b. Under the action of the engaging protrusion 15, the left sub-wall 14a and right sub-wall 14b generate a large friction force with the sliding grooves 23 on both sides, thereby increasing the connection stability between the reinforcing rib 24 and the clearance opening 17. This setting can further improve the slot's limitation on the reinforcing rib 24, reduce the possible shaking of the first mounting plate 2 after installation, and thus improve the installation stability of the first mounting plate 2.

[0042] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, the evaporator mounting structure includes a second mounting plate 3, which is fixed to the other end of the evaporator 4. The first mounting plate 2 and the second mounting plate 3 are arranged opposite to each other. The lower end of the second mounting plate 3 is provided with a third snap-fit ​​part 31. The second snap-fit ​​part 21 is located at the lower end of the first mounting plate 2. The second snap-fit ​​part 21 and the third snap-fit ​​part 31 are upwardly extending hook structures. The first snap-fit ​​part 12 is a first mounting port. The front side wall of the mounting groove 11 is provided with a second mounting port 16. The second snap-fit ​​part 21 hooks onto the first mounting port, and the third snap-fit ​​part 31 hooks onto the second mounting port 16.

[0043] Specifically, the second mounting plate 3 is fixed to the other end of the evaporator 4. The second mounting plate 3 is provided with a third snap-fit ​​part 31. Both the second snap-fit ​​part 21 and the third snap-fit ​​part 31 are upward-extending hook structures. The first snap-fit ​​part 12 on the front side of the mounting groove 11 is the first mounting port. The front side of the mounting groove 11 is also provided with a second mounting port 16. First, the first snap-fit ​​part 12 and the second snap-fit ​​part 21 are hooked onto the first mounting port and the second mounting port 16 respectively. Then, the first mounting plate 2 and the second mounting plate 3 are fixed on the mounting groove 11. With this setting, both the left and right ends of the evaporator 4 can be initially limited by the snap-fit ​​structure. Then, the evaporator 4 is fixed by other structures. This can improve the assembly efficiency of the evaporator 4 and ensure that both ends of the evaporator 4 can be accurately installed in the mounting groove 11. In some other embodiments, the first snap-fit ​​part 12 is a snap hook structure, the second snap-fit ​​part 21 and the third snap-fit ​​part 31 are bayonet structures, and a fourth snap-fit ​​part is provided on the front side wall of the mounting groove 11. The fourth snap-fit ​​part is a snap hook structure, and the snap hook structure is hooked onto the bayonet structure in a corresponding manner.

[0044] In some embodiments, such as Figure 6 and Figure 7As shown, the front side wall of the mounting groove 11 has two mounting protrusions 11a, which extend toward the rear side of the base 1. The first mounting port and the second mounting port 16 are respectively inserted through the two mounting protrusions 11a, and the first mounting port and the second mounting port 16 extend vertically. The second snap-fit ​​part 21 and the third snap-fit ​​part 31 are respectively hooked onto the first mounting port and the second mounting port 16 from bottom to top.

[0045] Specifically, the mounting protrusion 11a protrudes inward into the mounting groove 11 to approach the evaporator 4. Both the first mounting port and the second mounting port 16 extend vertically. The ends of the first mounting plate 2 and the second mounting plate 3 with snap-fit ​​parts are curved upwards, so that the second snap-fit ​​part 21 and the third snap-fit ​​part 31 hook onto these two mounting ports from bottom to top. This arrangement facilitates installation at both ends of the evaporator 4 and prevents the second snap-fit ​​part 21 and the third snap-fit ​​part 31 from easily detaching from the two mounting ports, further improving the installation stability of the evaporator 4. In some other embodiments, the first mounting port and the second mounting port 16 are directly provided through the front sidewall of the mounting groove 11.

[0046] In some embodiments, as Figure 6 and Figure 7 As shown, the mounting protrusion 11a includes a first crossbeam 19 and a plurality of reinforcing crossbeams 18. The first crossbeam 19 is connected to the side wall of the mounting groove 11 through the plurality of reinforcing crossbeams 18. The first crossbeam 19 and the plurality of reinforcing crossbeams 18 together form a first snap-fit ​​part 12 and a second mounting opening 16.

[0047] Specifically, each mounting protrusion 11a includes at least two reinforcing crossbeams 18 and a first crossbeam 19. The reinforcing crossbeams 18 connect the first crossbeam 19 and the front sidewall of the mounting groove 11, forming a first locking part 12 at the left end and a second mounting opening 16 at the right end. A first crossbeam 19 can also connect multiple reinforcing crossbeams 18, with a certain gap between them to reduce the weight of the base 1. This arrangement increases the structural strength of the mounting protrusion 11a, making the first and second mounting openings 16 less prone to deformation. This ensures that the second locking part 21 and the third locking part 31 can be stably hooked into these two mounting openings, improving the installation stability of the evaporator 4. Furthermore, when the first crossbeam 19 breaks under stress, it will not cause damage to the sidewall of the mounting groove 11, preventing leakage and affecting its use. Further, the first crossbeam 19, the reinforcing crossbeams 18, and the base 1 are integrally formed.

[0048] In some embodiments, as Figure 2 , Figure 3 and Figure 8As shown, the first mounting plate 2 is provided with a first through hole 25, which is used for a screw to pass through. The screw is screwed to the base 1 to fix the first mounting plate 2 to the base 1. The first through hole 25 is located between the second snap-fit ​​part 21 and the second plug-in part 22. The upper end of the second mounting plate 3 is provided with a second through hole 32, which is used for a screw to pass through to fix the second mounting plate 3 to the base 1.

[0049] Specifically, the first mounting plate 2 and the second mounting plate 3 are respectively provided with a first through hole 25 and a second through hole 32. Both through holes are used for screw connectors to pass through. After the screw connectors pass through, they are screwed into the mounting groove 11, thereby locking and fixing the first mounting plate 2 and the second mounting plate 3 to the base 1. This arrangement, with a screw connector on each mounting plate for fixing, can further increase the installation stability of the first mounting plate 2 and the second mounting plate 3.

[0050] On the other hand, embodiments of this application provide a refrigeration device, including the evaporator mounting structure as described above.

[0051] Specifically, the refrigeration equipment is an indoor air conditioning unit, and the evaporator mounting structure is located inside the outer casing of the indoor air conditioning unit.

Therefore, the content of this specification should not be construed as a limitation of this application.
