DETAILED DESCRIPTION

[0024] The utility model is further explained below in combination with the drawings.

[0025] According to Figures 1-10 As shown in the figure, the application embodiment proposes a mounting structure of air conditioner cabinet filter screen, including back frame 1, the back frame 1 is equipped with mounting end 5, the back frame 1 is provided with the evaporator bracket 2 that is arranged in the inside, the mounting gap for installing filter screen is equipped between the back frame 1 and the evaporator bracket 2, the guide rail assembly is arranged in the mounting gap, the back frame 1 is spaced apart and is provided with a plurality of first arc-shaped ribs 3, and a plurality of the first arc-shaped ribs 3 divide the back frame 1 into a plurality of air outlets 6, the evaporator bracket 2 is provided with a plurality of second arc-shaped ribs 4, a plurality of first arc-shaped ribs 3 and a plurality of second arc-shaped ribs 4 are one-to-one corresponding, the guide rail assembly includes the inner convex edge 7 and the outer convex edge 8 that are integrally arranged on the upper end of the first arc-shaped rib 3, the extension path of the inner convex edge 7 and the outer convex edge 8 is adapted to the first arc-shaped rib 3, the inner convex edge 7 and the outer convex edge 8 form the guide groove 9, and the guide groove 9 is used to be slid with the bottom end of filter screen.

[0026] A plurality of the first arc-shaped ribs 3 are spaced apart in the hollow part of the back frame 1 in the vertical direction, and the first arc-shaped rib 3 is horizontally arranged, a plurality of the first arc-shaped ribs 3 divide the back frame 1 into a plurality of air outlets 6, and the air outlet 6 is provided with a grid structure, forming external protection, the evaporator bracket 2 is connected to the inside of the back frame 1 by screw structure, the evaporator bracket 2 is provided with a plurality of second arc-shaped ribs 4 corresponding to the first arc-shaped rib 3, the second arc-shaped rib 4 and the corresponding first arc-shaped rib 3 are connected to form a positioning part, and a unit filter screen mounting part is formed between two adjacent positioning parts.

[0027] In the embodiment, the number of the first arc-shaped rib 3 and the second arc-shaped rib 4 is not less than 3, and the number of the divided air outlet 6 is not less than 3.

[0028] First of all, it needs to be pointed out that the inner convex edge 7 and the outer convex edge 8 are integrally arranged on the first arc-shaped rib 3, the inner convex edge 7 and the outer convex edge 8 are concentric circular arcs and the spacing therebetween is the same everywhere, thereby forming the guide groove 9 for installing the filter screen, which can ensure the integrity of the guide rail structure, without additional guide rail installation materials and steps, thereby reducing the cost, and the back frame 1 and the evaporator bracket 2 are connected and installed to form the filter screen mounting structure, thereby improving the installation efficiency.

[0029] Specifically, due to the limitation of the existing mold stripping technology, the design of the inner convex edge 7 and the outer convex edge 8 on the first arc-shaped rib 3 can only realize that the inner convex edge 7 is shorter than the outer convex edge 8, so that a gap appears at the position where the end of the inner convex edge 7 is short, at this time, it is possible that the user will mistakenly insert the filter screen into the gap when installing the filter screen, and repeated pulling will cause damage to the filter screen or the evaporator, which seriously affects the normal use of the user. In order to solve the above problems, one end of the second arc-shaped rib 4 close to the mounting end 5 is provided with a baffle 10, the guiding gap 11 is formed between the baffle 10 and the outer convex edge 8, and the end of the baffle 10 away from the mounting end 5 contacts the end of the inner convex edge 7 close to the mounting end 5. The gap formed by the baffle 10 and the outer convex edge 8 is connected with the guiding groove 9 formed by the inner convex edge 7 and the outer convex edge 8 to form a stable guide rail structure, which ensures the stability and accuracy of the filter screen installation process.

[0030] In order to further improve the installation efficiency and stability, one of the second arc-shaped ribs 4 is provided with two oppositely arranged baffles 10, a limiting gap 14 is arranged between the two baffles 10, and the first arc-shaped rib 3 is embedded in the limiting gap 14. During installation, the first arc-shaped rib 3 is directly embedded in the limiting gap 14 to realize quick docking and matching, and it is not easy to slide and deviate after docking, so the stability is high.

[0031] Specifically, one side of the baffle 10 relative to the outer convex edge 8 is provided with a first arc-shaped surface 12 which is arranged to be adapted to the curvature of the outer convex edge 8, so as to ensure accurate guidance after the filter screen is inserted; the side of the baffle 10 contacting the inner convex edge 7 is arranged as a second arc-shaped surface 13 which is curved towards the outer convex edge 8, so that the end of the filter screen is prevented from being stuck in the contact part of the baffle 10 and the inner convex edge 7 during the insertion process, and the efficiency of filter screen installation is improved.

[0032] In order to further improve the smoothness and efficiency of the installation process, the end of the inner convex edge 7 away from the mounting end 5 is provided with a break, that is, the inner convex edge 7 is cut off at a predetermined position on the side of the first arc-shaped rib 3 away from the mounting end 5, so that the guiding groove 9 is cut off, and only the outer convex edge 8 continues to extend, thereby improving the problem that the filter screen becomes tighter or less smooth when inserted further during the installation process.

[0033] In summary, the utility model provides an installation structure of a filter screen of a cabinet air conditioner, which improves the installation efficiency and reduces the cost through the integrated guide rail, and the integrated guide rail is formed after the first arc-shaped rib 3 and the second arc-shaped rib 4 are docked and installed through the arrangement of the baffle 10, thereby reducing the difficulty of mold stripping of the integrated guide rail. Moreover, the break design improves the installation efficiency on the basis of maintaining the stable guiding and clamping effect, and the arrangement of the first arc-shaped surface 12 and the second arc-shaped surface 13 can ensure accurate guidance during the filter screen installation process, avoid jamming, and improve the efficiency.
