[0031] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0032] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.
[0033] In the embodiments of this utility model, such as Figures 1-9 As shown, the rear frame structure includes: a rear frame body 1 and a purification component; the rear frame body 1 is provided with an air inlet 2; the purification component includes a first purification module 3 and a second purification module 4 that are independently arranged, and one of the first purification module 3 and the second purification module 4 can be selectively and detachably installed on the rear frame body 1 to cover the air inlet 2 to form a first purification mode and a second purification mode.
[0034] The first purification module 3 and the second purification module 4 have the same installation path, and the first purification mode and the second purification mode are used to purify air pollutants of different particle sizes.
[0035] Specifically, in this embodiment of the invention, the rear frame body 1 is provided with an air inlet 2. To increase the air intake area of the air inlet 2, the air inlet 2 at least partially covers the upper and middle parts of the rear frame body 1. In addition, to avoid affecting the structural strength of the rear frame body 1 due to the excessive size of the air inlet 2, multiple reinforcing ribs are arranged at the air inlet 2. The multiple reinforcing ribs can improve the overall structural strength of the rear frame body 1 on the one hand, and divide the incoming air into multiple air intake zones on the other hand. A purification module is provided in each air intake zone, thereby purifying air pollutants.
[0036] In this embodiment of the invention, the purification component includes a first purification module 3 and a second purification module 4. The two purification modules are independently configured, and one can be selectively installed on the rear frame body 1 to cover the air inlet 2, thus forming a corresponding purification mode. Furthermore, to facilitate installation and / or switching of the purification modules, the purification modules are detachably connected to the rear frame body 1. For example, installing the first purification module 3 on the rear frame body 1 forms the first purification mode; conversely, removing the first purification module 3 and installing the second purification module 4 on the rear frame body 1 forms the second purification mode, allowing for reasonable selection of the appropriate purification mode according to user needs. Therefore, the first purification module 3 and the second purification module 4 can use different purification modes to purify air pollutants of different particle sizes. For example, the first purification module 3 can use deep purification, while the second purification module 4 can use basic filtration, improving its practicality and economy.
[0037] On the other hand, the first purification module 3 and the second purification module 4 share the same installation path, eliminating the need for additional installation structures, thus simplifying the production process and reducing mold development costs. Furthermore, users can easily switch purification modes through simple disassembly / installation operations, significantly improving ease of use.
[0038] This embodiment sets up a first purification module 3 and a second purification module 4 that are independent of each other, so that the two purification modules can be selectively installed at the air inlet 2 of the rear frame body 1, thereby forming different purification modes. The appropriate purification mode can be selected according to actual needs, and the two modes can be interchanged. At the same time, the two purification modules have the same installation path, which improves the practicality and economy of the structure.
[0039] like Figure 3 , Figures 6-11As shown, in one embodiment, both the first purification module 3 and the second purification module 4 are connected to the rear frame body 1 via a first mounting component. The first mounting component includes a guide rib 5 and a guide groove 6, with the guide rib 5 sliding into the guide groove 6. Specifically, to allow the purification modules to be detachably installed on the rear frame body 1, this embodiment uses guide ribs 5 and guide grooves 6. Under external force, the guide rib 5 can slide into the guide groove 6, achieving a detachable connection between the two. After the external force disappears, the guide rib 5 can remain in the guide groove 6, avoiding the installation and disassembly difficulties caused by screw fixing. Simultaneously, the sliding cooperation between the guide rib 5 and the guide groove 6 improves the installation efficiency of the purification modules. In this embodiment, the connection between the first purification module 3 and the rear frame body 1, and between the second purification module 4 and the rear frame body 1, both employ the aforementioned connection method of guide ribs 5 and guide grooves 6. The same mounting structure creates the same installation path, ensuring that after disassembling any purification module, the other purification module can be installed on the rear frame body 1 in the same way. Of course, since the air inlet 2 is divided into multiple air inlet zones, in order to improve the installation stability of the corresponding purification modules, this embodiment sets a set of guide ribs 5 and guide grooves 6 at the opposite end faces of the purification modules and the corresponding opposite end faces of the air inlet zones, respectively. The symmetrical installation method can improve the installation stability of the purification modules, make them bear force evenly, and prevent them from falling.
[0040] like Figure 10 As shown, in one embodiment, the cross-sectional area of the guide groove 6 gradually decreases along the sliding direction of the guide rib 5. Specifically, in order to improve the connection tightness between the guide rib 5 and the guide groove 6 and prevent the guide rib 5 from freely sliding out of the guide groove 6, this embodiment utilizes a guide groove 6 with a variable cross-section, allowing the guide rib 5 to slide from the large-diameter end of the guide groove 6 into its small-diameter end, and using the inner wall of the small-diameter end to form contact friction with the guide rib 5, thereby retaining the guide rib 5 within the guide groove 6.
[0041] Furthermore, such as Figure 10 As shown, in one embodiment, the guide groove 6 has several limiting protrusions 7 at its smallest cross-sectional area, which abut against the guide rib 5. Specifically, to intuitively understand the installation status of the guide rib 5, this embodiment sets a limiting protrusion at the small-diameter end of the guide groove 6. When the guide rib 5 slides to abut against the limiting protrusion, it can restrict the guide rib 5 from continuing to move, thereby providing feedback to the user on its positioning. Conversely, if the guide rib 5 does not abut against the limiting protrusion, it indicates that it still has room to move. Furthermore, setting two limiting protrusions at opposite inner walls of the guide groove 6, using a symmetrical limiting method, avoids misjudgment and also ensures that the guide rib 5 is subjected to balanced forces.
[0042] Furthermore, in one embodiment, one of the guide rib 5 and the guide groove 6 is disposed on the rear frame body 1, and the other is disposed on the first purification module 3 and the second purification module 4, for forming a limiting fit along the first direction. In this embodiment, as... Figures 8-10 As shown, guide ribs 5 are placed at the upper and lower end faces of each air inlet zone, as follows. Figure 3 , Figure 6 As shown, the guide groove 6 is set at the upper and lower end faces of the first purification module 3 / second purification module 4. Under the action of external force, the purification module can be pushed out to the corresponding air inlet area. With the cooperation of the guide rib 5 and the guide groove 6, the purification module can be restricted from moving in the vertical direction.
[0043] like Figure 3 , Figures 6-11 As shown, in one embodiment, the first purification module 3 and the second purification module 4 are both connected to the rear frame body 1 via a second mounting assembly. The second mounting assembly includes multiple positioning ribs 8 and multiple positioning holes 9, with each positioning rib 8 and positioning hole 9 corresponding to the other, and the positioning rib 8 extending into the positioning hole 9. Specifically, to further improve the installation stability of the rear frame body 1 and the purification modules, this embodiment uses a second mounting assembly for connection between the first purification module 3 and the rear frame body 1, and between the second purification module 4 and the rear frame body 1. This second mounting assembly includes positioning ribs 8 and positioning holes 9. Under external force, the positioning ribs 8 can extend into the positioning holes 9, thus achieving a detachable connection between the purification module and the rear frame body 1. Of course, the one-to-one correspondence between the multiple positioning ribs 8 and the multiple positioning holes 9 allows different positions of the purification module to be connected to the rear frame body 1.
[0044] Furthermore, one of the positioning rib 8 and the positioning hole 9 is provided in the rear frame body 1, and the other is provided in the first purification module 3 and the second purification module 4, for forming a limiting fit along the second direction. In this embodiment, as... Figures 7-10 As shown, multiple positioning ribs 8 are spaced apart along the vertical direction at the air inlet 2 of the rear frame body 1, as follows: Figure 3 , Figure 6 As shown, multiple positioning holes 9 are spaced apart along the vertical direction at the first purification module 3 / second purification module 4; thus, when the positioning rib 8 is inserted into the positioning hole 9, the purification module can be restricted from moving to the left. Of course, the positioning rib 8 and positioning hole 9 described above can also be provided on the other side of each component.
[0045] like Figure 3 , Figure 6 and Figure 11As shown, in one embodiment, the second mounting assembly further includes a plurality of rear frame spring clips 10 and a plurality of purification module spring clips 11. The plurality of rear frame spring clips 10 and the plurality of purification module spring clips 11 are arranged in a one-to-one correspondence, and the two can be detachably connected to form a limiting fit along a third direction. Specifically, in order to restrict the purification module from moving to the right, this embodiment provides a rear frame spring clip 10 on one side of the rear frame body 1 and a purification module spring clip 11 on the same side of the purification module. By pressing one spring clip into another spring clip, a detachable connection between the rear frame body 1 and the purification module can be achieved, and the purification module can be restricted from moving in the left and right directions with the cooperation of the positioning rib 8 and the positioning hole 9.
[0046] like Figure 1 and Figure 4 As shown, in one embodiment, at least one of the first purification module 3 and the second purification module 4 is flush with the surface of the rear frame body 1. This eliminates the abruptness of the purification modules, making the overall appearance simpler and smoother, reducing space encroachment when the equipment is installed or placed against a wall, and is suitable for confined space scenarios.
[0047] This embodiment also provides an air conditioner, including the rear frame structure described above. The specific structure of the rear frame structure is as described in the above embodiment. Since this air conditioner adopts all the technical solutions of 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.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
