Description

Technical Field

[0001] The present application relates to the technical field of air conditioning filters, and in particular to a filter assembly and an air conditioner. Background Art

[0002] The filter assembly of the existing air conditioner mainly includes a frame and a filter mesh material. The frame is connected to the filter mesh material through a plurality of staggered extending ribs. During the disassembly and assembly process, the disassembly and assembly personnel mainly pinch the ribs on the frame with their hands, and then install the filter assembly on the air conditioner or remove it from the air conditioner. However, because the ribs on the frame are thin and close to the filter mesh material, the disassembly and assembly personnel's hands have a small grip area on the ribs, which makes it easy for the filter assembly to fall, resulting in inconvenient disassembly and assembly of the filter assembly. In response to this, some existing filter assemblies also have a lifting structure on the surface of the frame to facilitate lifting the filter assembly, but the lifting structure will protrude from the surface of the air conditioner, affecting the appearance of the air conditioner.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] An embodiment of the present application provides a filter assembly to solve the problem that the existing filter assembly is not convenient enough to be disassembled and assembled, and will be described below with reference to the accompanying drawings.

[0027] In the embodiments of the present application, Figure 1 and Figure 2As shown, the filter assembly 100 includes a frame 10 and a filter mesh material 20, wherein the frame 10 has a relative windward surface 11 and a leeward surface 12. When the filter assembly 100 is installed in the air inlet 211 of the air conditioner 200, the windward surface 11 of the frame 10 faces the outside of the air conditioner 200, and the leeward surface 12 faces the inside of the air conditioner 200. The frame 10 encloses and forms a vent 13, and the vent 13 runs from the windward surface 11 to the leeward surface 12. When the filter assembly 100 is installed in the air inlet 211 of the air conditioner 200, the vent 13 is correspondingly connected to the air inlet 211 on the air conditioner 200. In addition, the size and material of the frame 10 can be flexibly designed according to actual conditions. For example, referring to the figure, the size of the frame 10 is sufficient to cover the air inlet 211 on the air conditioner 200, and the frame 10 can be made of plastic, metal, alloy and other materials.

[0028] The filter mesh material 20 is a sheet structure with ventilation holes, which is generally made of metal wire, synthetic fiber, plastic and other materials. The specific material can be selected according to actual needs. For example, when it is necessary to filter tiny particles, ultrafine fibers or nanofiber materials with high filtration accuracy can be used to make the filter mesh material 20.

[0029] In this embodiment, the filter mesh material 20 is fixed on the frame 10, and the filter mesh material 20 covers the vent 13, and then the airflow at the vent 13 can be filtered. There are many ways to fix the filter mesh material 20 on the frame 10, such as the filter mesh material 20 can be directly connected to the frame 10 by means of clamping, bonding, hanging, binding, etc. For another example, when the frame 10 is produced by mold injection, the filter mesh material 20 can be placed in the mold for producing the frame 10, and part of the surface of the filter mesh material 20 is located in the molding cavity of the mold, and then when the molten plastic solidifies into the frame 10, the filter mesh material 20 is naturally bonded and fixed to the frame 10. For another example, a rack rod can be integrally formed on the filter mesh material 20, and then plugged or clamped to the frame 10 through the rack rod. In short, the fixing method of the filter mesh material 20 on the frame 10 can be flexibly selected according to actual needs, as long as the filter mesh material 20 can be stably connected to the frame 10.

[0030] It should be emphasized that the filter mesh material 20 in the present application also forms a recessed area 21, such as Figure 1 and Figure 2As shown, the recessed area 21 is recessed relative to the windward surface 11 toward the side where the leeward surface 12 is located. Specifically, a part of the filter mesh material 20 is recessed toward the side where the leeward surface 12 is located to form the recessed area 21. The filter surface in the recessed area 21 is not flush with the windward surface 11 of the frame 10. When the filter assembly 100 is installed on the air conditioner 200, the recessed area 21 is recessed into the interior of the air conditioner 200. It can be understood that this can increase the filter area of ​​the filter assembly 100, thereby improving the filtering effect and slowing down the dirty clogging speed.

[0031] It should be noted that the size, shape, number, depth, etc. of the recessed area 21 can be flexibly designed according to needs. For example, in this embodiment, reference can be made to Figure 1 , the recessed area 21 extends along the length direction of the frame 10, and two recessed areas 21 are formed on the filter mesh material 20, and the two recessed areas 21 are arranged at intervals along the width direction of the frame 10, and the width of each recessed area 21 is approximately one-third of the width of the entire filter mesh material 20. Of course, in other embodiments, the number of recessed areas 21 can be one, and the width of the one recessed area 21 is substantially the same as the width of the entire filter mesh material 20, or the width of the one recessed area 21 is one-half, two-thirds, one-quarter, etc. of the entire filter mesh material 20.

[0032] As for the depth of the depression area 21, it can be designed according to the size of the space in the air conditioner 200 for accommodating the depression area 21, the distance between the top surface of the air conditioner 200 and the ceiling, the size of the lifting portion 14 to be set, etc., as long as the depression area 21 is large enough to accommodate the lifting portion 14 and does not affect the disassembly and assembly. For example, in one embodiment, part of the filter surface in the depression area 21 is also bent toward the windward surface 11 to form a bending area, so that the depression depth of the depression area 21 can be reduced without reducing the filter area of ​​the filter assembly 100, and then when the filter assembly 100 is disassembled, it is not necessary to pull the filter assembly 100 out or lift it to a higher height, making the disassembly and assembly of the filter assembly 100 more convenient.

[0033] In the present application, in order to facilitate the lifting and disassembly of the filter assembly 100, a lifting portion 14 is further provided on the frame 10, and the lifting portion 14 is located in the recessed area 21. Specifically, the shape of the lifting portion 14 can be a strip, a block, a plate, or other shapes that are convenient for pinching and lifting, for example, Figure 1 In the illustrated embodiment, the lifting portion 14 is plate-shaped, which is not only simple in structure and easy to produce, but also can provide a larger gripping area, thereby making it more convenient for disassembly and assembly personnel to grip and lift the filter assembly 100 more stably, thereby preventing the filter assembly 100 from falling during the disassembly and assembly process.

[0034] It can be understood that because the lifting portion 14 is located in the recessed area 21, the lifting portion 14 can be set larger to facilitate the disassembly and assembly personnel to hold and disassemble, and the lifting portion 14 will not protrude from the surface of the air conditioner, thereby ensuring the appearance of the air conditioner.

[0035] As for the size of the lifting portion 14, since the disassembler usually holds the lifting portion 14 with the thumb and index finger when lifting, the size of the lifting portion 14 can be designed according to the principle of "sufficient for an adult's thumb and index finger to hold, and the thumb and index finger will not contact the filter material 20 when holding". Of course, the larger the lifting portion 14, the more convenient it is to lift. At this time, it is only necessary to control the production cost, product volume, weight, etc. In addition, the number of lifting portions 14 can also be flexibly selected according to needs. For example, the number of lifting portions 14 can be one, and the lifting portion 14 can extend along the length direction of the frame 10 to facilitate the disassembler to lift with both hands at the same time; or, the number of lifting portions 14 can be two, so as to correspond exactly to the disassembler's hands; or, three or more lifting portions 14 can be provided to facilitate the disassembler to select different lifting positions according to needs.

[0036] Optionally, in one embodiment, as Figure 1 and Figure 2 As shown, the lifting portion 14 is plate-shaped, and the plate surface of the lifting portion 14 extends along the depth direction of the recessed area 21. For example, reference can be made to Figure 2 When the filter assembly 100 is installed horizontally, the windward surface 11 and the leeward surface 12 are the upper surface and the lower surface of the frame 10 respectively, and the recessed area 21 is recessed downward, so the plate surface of the lifting portion 14 also extends up and down. It can be understood that in this way, on the basis of ensuring that the lifting portion 14 has a sufficient lifting area, it is possible to avoid the lifting portion 14 from generating a large wind resistance and ensure the ventilation volume at the vent 13.

[0037] Furthermore, on the basis that the plate surface of the lifting portion 14 extends along the depth direction of the recessed area 21, the plate surface of the lifting portion 14 may also extend along the length direction of the frame 10, or along the width direction of the frame 10, or be inclined relative to the length direction or width direction of the frame 10, and the specific selection can be made according to actual needs. Figure 1 In the illustrated embodiment, the plate surface of the lifting portion 14 also extends along the width direction of the frame 10, and at least two lifting portions 14 are provided, and at least two lifting portions 14 are spaced apart along the length direction of the frame 10, so that it is more convenient for the disassembly and assembly personnel to lift and the wind resistance caused by the lifting portion 14 can be minimized.

[0038] Optionally, in one embodiment, please combine Figure 1 and Figure 2The frame 10 has a front side 15 and a rear side 16 that are opposite to each other along its width direction. A buckle 17 is provided on the front side 15, and a positioning pin 18 is provided on the rear side 16. The body 210 of the air conditioner 200 is provided with corresponding clamping holes (not shown) and positioning sockets (not shown). When installing the filter assembly 100 on the air conditioner 200, the positioning pin 18 on the frame 10 can be first inserted into the positioning socket on the body 210 to achieve rapid positioning of the filter assembly 100, and then the front side 15 of the frame 10 is pressed down until the buckle 17 is clamped into the clamping hole on the body 210, so that the filter assembly 100 can be fixed. You can refer to Figure 6 When the filter assembly 100 is installed, the front side 15 of the frame 10 is closer to the front surface of the body 210, and the rear side 16 is closer to the wall.

[0039] In addition, in this embodiment, at least part of the recessed area 21 is also disposed close to the front side 15. Specifically, Figure 1 As shown, two recessed areas 21 are formed on the filter mesh material 20 , wherein one recessed area 21 is close to the rear side 16 and extends along the rear side 16 , and the other recessed area 21 is close to the front side 15 and extends along the front side 15 .

[0040] For the frame 10 of the above structure, the lifting portion 14 is arranged at the front side 15 in this embodiment. For details, please refer to Figure 3 In the width direction of the frame 10, the lifting portion 14 has a first end 141 and a second end 142 opposite to each other, the first end 141 is connected to the front side 15, and the second end 142 extends into the recessed area 21. It can be understood that when the lifting portion 14 is connected to the front side 15, the hands of the disassembling personnel can be closer to the front side 15, and then when the positioning pin 18 on the rear side 16 is inserted into the positioning socket on the body 210, the disassembling personnel can directly apply force downward to make the buckle 17 on the front side 15 snap into the snap hole on the body 210, without having to release the lifting portion 14 first and then press the front side 15 of the frame 10, so that the installation of the filter assembly 100 is more convenient and quick.

[0041] It should be noted that the second end 142 of the lifting portion 14 can be suspended, connected to the filter mesh material 20, or connected to other structures arranged in the recessed area 21. For example, Figure 1 and Figure 2In the illustrated embodiment, a first connecting rib 30 is further provided in the recessed area 21, and the second end 142 is connected to the first connecting rib 30. Specifically, the first connecting rib 30 extends along the length direction of the frame 10, and both ends of the first connecting rib 30 in the length direction are connected to the frame 10 or other ribs, plates, etc. connected to the frame 10, and the second end 142 of the lifting portion 14 is integrally formed with the first connecting rib 30. It can be understood that this can improve the structural stability of the lifting portion 14, avoid shaking, deformation, etc. of the lifting portion 14 when subjected to force, and ensure that the disassembly personnel can stably lift the filter assembly 100.

[0042] Optionally, in one embodiment, as Figure 2 As shown, in the depth direction of the recessed area 21, the lifting portion 14 has a first side 143 and a second side 144 opposite to each other, the first side 143 is closer to the filter mesh material 20 than the second side 144, and the first side 143 is connected to the filter mesh material 20, that is, part of the surface of the filter mesh material 20 is also fixedly connected to the frame 10 through the lifting portion 14, which can further improve the connection stability between the filter mesh material 20 and the frame 10. That is to say, in this embodiment, in addition to facilitating the disassembly personnel to lift the filter assembly 100, the lifting portion 14 can also strengthen the connection strength between the filter mesh material 20 and the frame 10.

[0043] It should be noted that in this embodiment, the first side edge 143 may be partially connected to the filter mesh material 20, or the entire surface may be connected to the filter mesh material 20. Figure 1 , Figure 4 and Figure 5 The frame 10 is also provided with a second connecting rib 40, and a plurality of second connecting ribs 40 are provided, and the plurality of second connecting ribs 40 are arranged at intervals along the length direction of the frame 10, and each second connecting rib 40 is connected to the front side 15 of the frame 10 at one end, and connected to the rear side 16 of the frame 10 at the other end, and each second connecting rib 40 includes at least one concave section 41, Figure 1 , Figure 4 or Figure 5 In the structural solution shown, two recessed sections 41 are provided, wherein one recessed section 41 is disposed close to the front side 15 , and the other recessed section 41 is disposed close to the rear side 16 . The two recessed sections 41 are connected by a connecting section 42 .

[0044] The recessed section 41 is bent toward the side where the leeward surface 12 is located. If the windward surface 11 is the upper surface of the frame 10, the recessed section 41 is bent downward from the windward surface 11. The filter mesh material 20 is connected to the second connecting rib 40 and extends along the second connecting rib 40. Because the recessed section 41 is bent toward the side where the leeward surface 12 is located, the portion of the filter mesh material 20 extending along the recessed section 41 forms a recessed area 21 that is recessed downward.

[0045] Among them, it can be combined Figure 1 , Figure 3 and Figure 5 The first side 143 of the lifting portion 14 is spaced opposite to a part of the recessed section 41 along the length direction of the frame body 10. Specifically, because the lifting portion 14 is connected to the front side 15 of the frame body 10, the recessed section 41 on the second connecting rib 40 close to the front side 15 is spaced opposite to the first side 143 of the lifting portion 14 along the length direction of the frame body 10, and in the present embodiment, the first side 143 extends parallel to the recessed section 41. When the first side 143 is projected toward the recessed section 41 along the length direction of the frame body 10, the first side 143 extends just parallel to the extension direction of the recessed section 41.

[0046] It can be understood that such a configuration can enable the first side 143 of the lifting portion 14 to be completely connected to the filter mesh material 20 , thereby further increasing the connection area and connection strength with the filter mesh material 20 .

[0047] Optionally, in one embodiment, as Figures 1 to 3 As shown, the frame 10 is also provided with a third connecting rib 50, which extends parallel to the second connecting rib 40, and the third connecting rib 50 is arranged along the width direction of the frame 10 corresponding to the lifting portion 14, and the filter mesh material 20 is also connected to the second connecting rib 40 and extends along the second connecting rib 40. Specifically, the third connecting rib 50 and the second connecting rib 40 are spaced and opposite to each other along the length direction of the frame 10, and the third connecting rib 50 extends parallel to the second connecting rib 40, and different from "both ends of the first connecting rib 30 are connected to the frame 10", the third connecting rib 50 is connected to the rear side 16 of the frame 10 at one end, and connected to the first connecting rib 30 at the other end, and the end of the third connecting rib 50 connected to the first connecting rib 30 is arranged corresponding to the lifting portion 14.

[0048] Therefore, the third connecting rib 50 is also formed with a recessed section 41 close to the rear side 16, and when the filter mesh material 20 is connected to the third connecting rib 50 and extends along the third connecting rib 50, the filter mesh material 20 is also formed with a recessed area 21 close to the rear side 16. At the same time, because the third connecting rib 50 is also arranged corresponding to the lifting portion 14, and the first side 143 of the lifting portion 14 extends parallel to the recessed section 41 of the second connecting rib 40, the third connecting rib 50 and the first side 143 of the lifting portion 14 are equivalent to a second connecting rib 40, and then under the joint restriction of the third connecting rib 50 and the lifting portion 14, the filter mesh material 20 can form a recessed area 21 close to the front side 15 at the third connecting rib 50.

[0049] It can be understood that by providing the second connecting rib 40 and arranging the second connecting rib 40 along the width direction of the frame 10 corresponding to the lifting portion 14, not only can the connection strength of the filter mesh material 20 on the frame 10 be improved, but also the structure of the entire filter assembly 100 can be made more regular and simple, so as to facilitate the production of the filter assembly 100.

[0050] Optionally, in one embodiment, as Figure 3 As shown, the second side 144 includes a flat section 1441 and a curved section 1442 connected to each other. One end of the flat section 1441 is connected to the frame 10, and the other end is connected to one end of the curved section 1442. The other end of the curved section 1442 extends into the recessed area 21, and one end of the curved section 1442 extending into the recessed area 21 is connected to the first connecting rib 30. The surface of the flat section 1441 is flush with the windward surface 11, which is convenient for the hands of the disassembly personnel to contact the lifting portion 14 and can prevent the lifting portion 14 from protruding from the windward surface 11 of the frame 10. The curved section 1442 is bent toward the side where the flat section 1441 is located, which can reduce the weight and windproof area of ​​the lifting portion 14, and make the lifting portion 14 more compatible with the recessed section 41 of the second connecting rib 40 in appearance, thereby improving the appearance of the filter assembly 100.

[0051] An embodiment of the present application also provides an air conditioner, which includes a body and a filter assembly. The body is provided with an air inlet, and the filter assembly is installed in the air inlet. The specific structure of the filter assembly refers to the above embodiment.
