Detailed Implementation

[0028] Existing filters are generally flat, with a small effective filtration area, which affects the air intake of the air conditioner.

[0029] To address the aforementioned issues, this invention provides a filter assembly, an air inlet panel assembly, and an air conditioner, which can increase the effective filtration area of ​​the filter, thereby improving the problem of the filter affecting the air intake volume of the air conditioner.

[0030] The following describes in detail the overall structure, working principle, and technical effects of the filter assembly, air inlet panel assembly, and air conditioner provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1 The air conditioner 300 provided by this utility model is used for indoor air conditioning. The air conditioner 300 is a cabinet-type air conditioner.

[0032] Please refer to Figure 1 and Figure 2 In this embodiment, the air conditioner 300 includes an indoor unit body 310 and an air inlet panel assembly 200, with the air inlet panel 210 installed on the lower side of the indoor unit body 310. The fan installed in the indoor unit body 310 can draw in indoor air through the air inlet panel assembly 200, process it, and then deliver it into the room.

[0033] Please refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the air inlet panel assembly 200 includes an air inlet panel 210 and a filter assembly 100. The air inlet panel 210 is provided with an air inlet 211; the filter assembly 100 is installed on the inner side of the air inlet panel 210 and covers the air inlet 211.

[0034] Please refer to Figure 3 and Figure 4In this embodiment, the filter assembly 100 includes a filter frame 110 and a filter (not shown). The filter frame 110 has at least two filter frames 111 connected at an angle. The filter frames 111 are provided with wavy support portions 112. The filter is fixed to the support portions 112 and the filter frames 111 in a wavy shape.

[0035] In this embodiment, the filter frame 110 is configured to have at least two filter frames 111 connected at an angle. Since the angled setting has a larger area than the orthographic projection, the air intake can be increased. A wave-shaped support part 112 is provided in the filter frame 111, and the filter is fixed to the support part 112 and the filter frame 111 in a wave shape. This can further increase the effective filtration area of ​​the filter, thereby increasing the air intake.

[0036] Please refer to Figure 3 and Figure 4 Furthermore, the filter frame 111 includes a main frame 113 and two side frames 114. The two side frames 114 are connected at an angle to both sides of the main frame 113 in the width direction. The filter is fixed to the support 112, the main frame 113 and the side frames 114 in a wave-like shape.

[0037] In this embodiment, side frames 114 are provided on both sides of the main frame 113 in the width direction, which can further increase the area of ​​the filter frame 110 and the filter, thereby increasing the air intake volume.

[0038] Furthermore, the filter frame 111 also includes a bottom frame 119, which is angled to the bottom of the main frame 113 and connected to two side frames 114 at both ends. The bottom frame 119 is also provided with a wave-shaped support 112, and the filter is fixed to the support 112, the main frame 113, the side frames 114 and the bottom frame 119 in a wave shape.

[0039] In this embodiment, by setting a bottom frame 119 on the bottom wall of the main frame 113, the area of ​​the filter frame 110 and the filter can be further increased, thereby increasing the air intake volume.

[0040] It should also be noted that the side frame 114 and the bottom frame 119 are inclined outward relative to the main frame 113.

[0041] Please refer to Figure 3 and Figure 4 Furthermore, the support portion 112 extends in the width direction of the main frame 113. At least one of the main frame 113, the side frame 114, and the bottom frame 119 is provided with connecting ribs 115 that intersect with the support portion 112.

[0042] In this embodiment, the wavy support portion 112 extends along the width of the main frame 113, which facilitates the bonding and fixing of the filter screen. The interlacing connecting ribs 115 provided on the support portion 112 can support and fix the filter screen, and also improve the mechanical strength of the filter screen frame 110.

[0043] It should be noted that the support part 112 and the connecting rib 115 are generally arranged in a crisscross pattern to form a rectangular grid, which can provide better support for the filter screen.

[0044] Of course, in some other embodiments of this application, the support portion 112 is also provided to extend in the length direction of the main frame 113, while the connecting rib 115 is provided to extend in the width direction.

[0045] Please refer to Figure 3 and Figure 4 Furthermore, a limiting rib 116 protrudes from part of the connecting rib 115 toward the air inlet side of the filter frame 110, and the limiting rib 116 is configured to cooperate with the limiting groove provided in the air inlet panel 210. The filter is disposed on the side of the filter frame 110 located on the air outlet side.

[0046] In this embodiment, some connecting ribs 115 protrude from the air inlet side of the filter frame 110 and form limiting ribs 116 that cooperate with the air inlet panel 210. This not only enhances the strength of the filter frame 110, but also allows the limiting ribs 116 to cooperate with the limiting grooves of the air inlet panel 210 for positioning. Placing the filter on the air outlet side of the filter frame 110 facilitates assembly and cleaning.

[0047] It should be noted that the air inlet side of the filter frame 110 refers to the side of the filter frame 110 that is close to the air inlet panel 210, and the air outlet side of the filter frame 110 refers to the side of the filter frame 110 that is away from the air inlet panel 210.

[0048] Furthermore, the periphery of the side frame 114 and the bottom frame 119 is provided with flanges 117.

[0049] In this embodiment, flanges 117 are provided around the periphery of the side frame 114 and the bottom frame 119. These flanges 117 can cooperate with the slots provided on the panel to achieve positioning and installation, and can also improve the problem of air leakage.

[0050] Furthermore, the top of the main frame 113 is also provided with a flange 117. Overall, the filter frame 110 roughly forms a trapezoidal three-dimensional structure, which has a larger area than a planar structure.

[0051] Please refer to Figure 3 and Figure 4 Furthermore, a pull-out handle 118 is provided at the top of the main frame 113.

[0052] In this embodiment, a handle is provided on the top of the main frame 113 to facilitate the assembly and disassembly of the filter assembly 100.

[0053] Furthermore, the main frame 113, side frame 114, and bottom frame 119 are integrally formed.

[0054] This application integrates the main frame 113, side frame 114 and bottom frame 119 into one piece, which facilitates molding and assembly.

[0055] It should be noted that the filter frame 110 is generally integrally molded using an injection molding process.

[0056] Please refer to Figures 2 to 5 Furthermore, the air intake panel 210 is provided with four air inlets 211, corresponding to the main frame 113, the bottom frame 119 and the two side frames 114 respectively. Therefore, compared with the existing method of having only one air inlet 211, the area of ​​the air inlet 211 is also larger, thereby improving the air intake performance of the air conditioner.

[0057] Furthermore, the air inlet panel 210 includes a front panel 212, side panels 213, and a bottom panel 214. There are two side panels 213, which are respectively connected to the two sides of the front panel 212. The front panel 212 is provided with a first air inlet 215. The side panels 213 are connected to the sides of the front panel 212 and are provided with a second air inlet 216. The bottom panel 214 is connected to the bottom of the front panel 212 and is provided with a third air inlet 217.

[0058] This application provides a first air inlet 215, a second air inlet 216, and a third air inlet 217 on the front panel 212, side panel 213, and bottom panel 214, respectively, so that air can be introduced from different directions. This allows the air conditioner 300 to maintain good air intake performance in various installation environments, thereby improving air intake efficiency and air output effect, and thus improving user comfort.

[0059] Of course, in some embodiments of this application, an air inlet 211 may be provided only on the front panel 212.

[0060] Secondly, a snap-fit ​​groove 218 is provided on the inner side of the side panel 213, and the filter assembly 100 can be inserted into the snap-fit ​​groove 218 through the flange 117 provided on the periphery. The filter assembly 100 can be pulled out of the panel by pulling upwards to achieve cleaning. The snap-fit ​​groove 218 is formed by a boss 219 and a snap-fit ​​platform 220 spaced apart.

[0061] Please refer to Figures 2 to 5 Furthermore, the air inlet panel 210 has a limiting groove in the middle of the vertical direction that cooperates with the limiting rib 116, thereby limiting the problem of the filter assembly 100 moving relative to the air inlet panel 210 in the width direction.

[0062] In summary, this embodiment sets the filter frame 110 covering the air inlet 211 to have at least two filter frames 111 connected at an angle. Since the angled setting has a larger area than the orthographic projection, the air intake can be increased. Furthermore, a wave-shaped support part 112 is provided on the filter frame 111, and the filter is fixed to the support part 112 and the filter frame 111 in a wave shape. This further increases the effective filtration area of ​​the filter, making the effective filtration area of ​​the filter larger than the area of ​​the air inlet 211, thereby increasing the air intake.

[0063] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
