Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a filter assembly and an air conditioner. Background Art

[0002] The middle frame is an essential component of an air conditioner, housing the indoor heat exchanger and providing an air inlet for drawing in air for heat exchange. For wall-mounted indoor units, the air inlet is typically located at the top of the middle frame. A filter assembly is typically installed at the air inlet to filter the incoming air, blocking dust and other foreign matter from the air and reducing dust accumulation on the indoor heat exchanger, thereby ensuring efficient heat exchange.

[0003] Although some existing technologies set the filter body of the filter assembly to a downward concave shape to increase the contact area between the airflow and the filter body and improve the filtering effect, and use a bracket equipped with longitudinal ribs as the skeleton of the filter body to support the filter body, the filter assembly adopts the above form. However, during the manufacturing process of the filter assembly, the filter body needs to be laid in the deeper groove of the lower mold first. Since the filter body itself is elastic, it is not easy to lay the filter body flat. As a result, during the injection molding process of the bracket, the bracket and the filter body may not be fully fitted together, resulting in the situation where the edge of the filter body of the manufactured filter assembly is partially separated from the bracket, resulting in injection molding manufacturing defects of the filter assembly and a high production defect rate. Utility Model Content

[0004] The first purpose of the present invention is to provide a filter assembly to solve the technical problems in existing filter assemblies in which the filter body and the bracket may be partially separated, resulting in injection molding manufacturing defects of the filter assembly and a high production defect rate.

[0005] The filter assembly provided by the present invention includes a bracket and a filter body, the bracket includes a first connecting part, a second connecting part, and a first bracket and a second bracket that can be arranged at intervals, the first connecting part is connected to the first bracket and faces the second bracket, the second connecting part is connected to the second bracket and faces the first bracket; the filter body includes a first fixing part fixedly connected to the first bracket, a second fixing part fixedly connected to the second bracket, and a deforming part connecting the first fixing part and the second fixing part, the first fixing part, the deforming part and the second fixing part are arranged in sequence along the first direction; the first connecting part and the second connecting part are configured to be able to switch from a separated state where the two are separated to a connected state where the two are connected; the degree of bending of the deforming part in the connected state is greater than its degree of bending in the separated state; the spacing between the first bracket and the second bracket in the connected state is less than the spacing between the two in the separated state.

[0006] The beneficial effects brought by the filter assembly of the utility model are:

[0007] By providing a first connecting portion and a second connecting portion, the two can be switched from a separated state to a connected state. This allows the deformed portion of the filter body to be kept in a minimally bent state, or even straight, during the injection molding process of the bracket. This allows the filter body to be laid on a relatively flat surface before injection molding, allowing it to fit more tightly within the mold. The fit of the filter body within the mold is unaffected by the curvature of the filter body in the final product. Subsequently, during the injection molding process, areas of the bracket that require a close fit with the filter body can be better bonded to the filter body, thereby improving the yield rate and enhancing the reliability of the air conditioner filter assembly during use. This prevents air from leaking into the air conditioner through the gap between the filter body and the bracket due to separation, potentially contaminating the indoor heat exchanger. After injection molding, the first connecting portion can be reconnected to the second connecting portion, shortening the distance between the first and second brackets and bringing the first and second fixing portions closer together. This in turn increases the bending of the deformed portion, thereby enhancing filtration efficiency within a smaller area.

[0008] In an optional technical solution, the bracket also includes a flexible support member, which connects the first bracket and the second bracket, and the rigidity of the flexible support member in the first direction is smaller than that of the first bracket and the second bracket, and the flexible support member connects the deformation part; the root of the first connection part is arranged on the side of the first bracket facing the second bracket, and the root of the second connection part is arranged on the side of the second bracket facing the first bracket.

[0009] By arranging the first connecting part on the side of the first bracket facing the second bracket, and arranging the second connecting part on the side of the second bracket facing the first bracket, a force can be applied to the flexible support member at both ends of the length direction of the flexible support member to cause it to deform, thereby more comprehensively constraining the shape of the flexible support member, reducing or even eliminating the size of the area where its shape is uncontrolled, and ensuring that the filter body can have the expected shape.

[0010] In an optional technical solution, the first connecting portion is located at both ends of the first bracket; and the second connecting portion is located at both ends of the first bracket.

[0011] By placing the first connecting portion at each end of the first bracket and the second connecting portion at each end of the second bracket, the deformation of the flexible support members located at each end of the bracket can be controlled. Simultaneously, utilizing the connecting portions of the first and second brackets, the deformation of multiple flexible support members arranged side by side can be controlled. This improves the deformation consistency of each flexible support member and the shape consistency of the filter body. When the filter assembly is installed in a wall-mounted air conditioner indoor unit, interference with the heat exchanger can be avoided.

[0012] In an optional technical solution, the first connecting part has a first accommodating space, and the second connecting part has a first plug-in part, and the first accommodating space is used to accommodate the first plug-in part; when the bending degree of the deformation part decreases, the movement direction of the second connecting part relative to the first connecting part is the first direction, and a side wall of the first accommodating space in the first direction constitutes a first check portion, and the first plug-in part constitutes a second check portion on a side surface in the first direction, and the first check portion cooperates with the second check portion.

[0013] By providing a first stopper on the sidewall of the first receiving space in the first direction and a second stopper on the surface of the first plug-in portion of the second connecting portion in the first direction, the first and second stoppers cooperate to prevent the first plug-in portion from being removed from the first receiving space in the first direction. Thus, after injection molding is completed and the first plug-in portion is inserted into the first receiving space, the deformed portion is forced to bend concavely and maintain a stable state, thereby obtaining the desired concave filter assembly.

[0014] In an optional technical solution, the first connecting portion includes a first upper side wall and a first lower side wall opposite to each other, and the first upper side wall and the first lower side wall form the first accommodating space.

[0015] By setting a first upper side wall and a first lower side wall to form a first accommodating space, the first plug-in part can be limited in the up and down directions. When the first plug-in part is inserted into the first accommodating space and the filter assembly forms its final shape, it can avoid accidental force acting on the second connecting part in the up and down directions, causing the first connecting part to fall out of the first accommodating space.

[0016] In an optional technical solution, the first connecting part is located at both ends of the first bracket; the second connecting part is located at both ends of the second bracket; the first accommodating space is open in a direction away from the middle of the bracket, and the middle of the bracket is the center area of ​​the bracket at the line connecting the two first connecting parts.

[0017] The first connecting portion is disposed at both ends of the first bracket, and the second connecting portion is disposed at both ends of the second bracket, so that the first accommodating space opens in a direction away from the center of the bracket. After the filter assembly is installed in the air inlet of the wall-mounted air conditioner indoor unit, the sidewalls of the air inlet can be used to block the first plug-in portion from moving away from the center of the bracket, thereby preventing the filter assembly from falling out of the opening of the first accommodating space after installation, thereby ensuring normal use of the wall-mounted air conditioner indoor unit. When the filter assembly is removed from the middle frame, the second connecting portion can swing away from the center of the bracket, that is, swing outward, so that the first plug-in portion can easily disengage from the first accommodating space, releasing the connection between the first and second connecting portions, thereby allowing the deformed portion to unfold, facilitating cleaning of the filter body.

[0018] In an optional technical solution, the bracket also includes a third connecting part and a fourth connecting part, the third connecting part and the fourth connecting part are located in the middle of the bracket, the third connecting part is connected to the first bracket, and the fourth connecting part is connected to the second bracket; in the connected state, the third connecting part and the fourth connecting part are connected, and in the separated state, the third connecting part and the fourth connecting part are separated.

[0019] Because the first connecting portion is provided at both ends of the first bracket, and the second connecting portion is provided at both ends of the second bracket, the flexible support members at both ends of the bracket are directly deformed and stabilized in a bent state. However, the flexible support members in the remaining positions of the bracket require force transmission from other components to deform and stabilize them in a bent state. Therefore, the third and fourth connecting portions are provided in the middle of the bracket. When the third and fourth connecting portions are connected, they can directly pull the flexible support members located in the middle of the bracket to deform, thereby causing the filter body to form a bent shape. Moreover, the deformation effect of the adjacent flexible support members can be enhanced, so that the filter body as a whole is closer to the desired bent shape.

[0020] In an optional technical solution, the flexible support member has a thinning area, and the thinning area includes a first thinning area located in the middle of the length direction of the flexible support member.

[0021] By providing a thinned region, the stiffness of the thinned region is lower than that of the flexible support member outside the thinned region. Therefore, when the flexible support member is subjected to force, the deformation in the thinned region is significantly greater than that in the non-thinned region, which helps control the deformation position of the flexible support member. Furthermore, by providing a first thinned region in the middle of the flexible support member's length, the first thinned region can be used to form the angled portion where the two arms of the flexible support member's concave portion connect, thereby controlling the maximum deformation position of the flexible support member and reducing the deformation stress of the flexible support member.

[0022] In an optional technical solution, the thinning area includes a second thinning area located at the end of the flexible support member in the length direction.

[0023] Providing a second thinning zone at the end of the flexible support member in the longitudinal direction can reduce the stiffness of the end of the flexible support member in the longitudinal direction, which is beneficial for causing the flexible support member to deform relative to the parts connected to it, so as to control the deformation position of the flexible support member and reduce the deformation stress of the flexible support member.

[0024] The second object of the present invention is to provide an air conditioner to solve the technical problem that the filter body and the bracket in the filter assembly may be partially separated, resulting in injection molding manufacturing defects of the filter assembly and a high production defect rate.

[0025] The air conditioner provided by the utility model includes an air conditioner indoor unit, the air conditioner indoor unit includes a middle frame and any one of the above filter components, the middle frame is provided with an air inlet, and the filter component is installed at the air inlet.

[0026] By arranging the above-mentioned filter assembly in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned filter assembly, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] Before introducing the specific embodiments of this application, let's first explain the meaning of various directions or orientations in this application. In this embodiment, the filter assembly is used as an example for a wall-mounted air conditioner indoor unit. However, this does not prevent the product of this application from being applied to cabinet air conditioner indoor units or ceiling-mounted units. Of course, in addition to air conditioners, the filter assembly can also be applied to other devices or appliances that require air intake, such as air purifiers and bladeless fans.

[0049] Generally speaking, the air inlet 910 of the wall-mounted air-conditioning indoor unit is mostly set at the top of the wall-mounted air-conditioning indoor unit. Among them, the definition of direction in this application is as follows: the front refers to the side of the wall-mounted air-conditioning indoor unit facing the main indoor space, and the back refers to the side of the wall-mounted air-conditioning indoor unit facing the wall on which it is hung. The bottom refers to the side of the wall-mounted air-conditioning indoor unit facing the ground. Correspondingly, the top refers to the side of the wall-mounted air-conditioning indoor unit facing the roof. Left and right can be defined based on the above-mentioned front, back and bottom, that is, when the observer faces the wall on which the wall-mounted air conditioner is installed, the observer's left hand direction is the left side, and the observer's right hand direction is the right side.

[0050] Specifically in this embodiment, the rear ends of the bracket or the first bracket 430 or the second bracket 440 mentioned later refer to the left and right ends of the bracket or the first bracket 430 or the second bracket 440 when the filter assembly is installed in the wall-mounted air conditioner indoor unit, and the first side of the bracket refers to the lower surface of the bracket, and correspondingly, the second side refers to the upper surface of the bracket. That is, the first side is Figure 1-Figure 5 and Figure 7 The downward facing surface of the bracket shown in FIG and Figure 6 The upper surface of the bracket shown in the figure is the second side. Figure 1-Figure 5 and Figure 7 The upward facing surface of the bracket is shown and Figure 6 The downward-facing surface of the bracket is shown. The length direction of the flexible support member 300, described later, is the front-to-back direction, i.e., the extension direction of the second grid bars 420. When the upper surface of the filter assembly is installed horizontally, the first direction is from back to front, and the second direction is from front to back.

[0051] Example 1:

[0052] Figure 1 This is a schematic structural diagram of a bracket in a filter assembly provided in Example 1 of the present utility model; Figure 2 A schematic structural diagram of the filter assembly provided in Example 1 of the present utility model; Figure 3 This is a schematic diagram of the structure of the filter assembly provided in Example 1 of the present invention after the injection molding process is completed; Figure 1-Figure 3As shown, the filter assembly provided by the first embodiment of the present invention includes a bracket and a filter body 700. The bracket includes a first connecting portion 100, a second connecting portion 200, and a first bracket 430 and a second bracket 440 that can be arranged at intervals. The first connecting portion 100 is connected to the first bracket 430 and faces the second bracket 440, and the second connecting portion 200 is connected to the second bracket 440 and faces the first bracket 430. The filter body 700 includes a first fixing portion 710 fixedly connected to the first bracket 430, a second fixing portion (not shown in the figure) fixedly connected to the second bracket 440, and a deforming portion 720 connecting the first fixing portion 710 and the second fixing portion. The first fixing portion 710, the deforming portion 720 and the second fixing portion are arranged in sequence along a first direction. The first connecting portion 100 and the second connecting portion 200 are configured to be switchable from a separated state to a connected state. The bending degree of the deforming portion 720 in the connected state is greater than the bending degree in the separated state. The spacing between the first bracket 430 and the second bracket 440 in the connected state is less than the spacing between the two in the separated state.

[0053] By providing the first connecting portion 100 and the second connecting portion 200 to switch between a separated state and a connected state, the deformed portion 720 of the filter body 700 can be kept in a less bent state, or even straight, during the bracket injection molding process. This allows the filter body 700 to be laid on a relatively flat surface before injection molding, allowing it to fit more closely within the mold. The fit between the filter body 700 and the mold is unaffected by the curvature of the filter body 700 in the final product. Subsequently, during the injection molding process, areas of the bracket that require a close connection with the filter body 700 can be better bonded to the filter body 700, thereby improving the yield rate and enhancing the reliability of the air conditioner filter assembly during use. This prevents air from leaking into the air conditioner through the gap between the filter body 700 and the bracket, potentially contaminating the indoor heat exchanger, due to separation of the filter body 700 from the bracket. After the injection molding is completed, the first connecting part 100 can be connected to the second connecting part 200, thereby shortening the distance between the first bracket 430 and the second bracket 440, so that the first fixing part 710 and the second fixing part are close to each other, driving the deformation part 720 to increase the bending degree, thereby achieving the effect of improving the filtering effect in a smaller range.

[0054] In this embodiment, the filter body 700 can be arranged at the lower part or lower side of the bracket. Being arranged at the lower part of the bracket means that the solid material of the bracket is also present below the filter body 700, because during the injection molding process of the bracket, the material forming the bracket can be injected into the lower side of the filter body 700. That is, material is injected and solidified on both the upper and lower sides of the filter body 700, and a portion of the filter body 700 is cast in the material of the bracket. In this embodiment, the filter body 700 can be located in the lower middle part of the bracket, relatively close to the lower surface of the bracket - the first side. When the deformation portion 720 is deformed, it bulges downward, that is, it bulges in the direction of the first side. Alternatively, the filter body 700 can also be located on the lower side of the bracket, that is, before injection molding, the filter is attached to the lower surface of the mold, and after injection molding, the filter is fused with the lower surface of the bracket.

[0055] It should be noted that the connection between the first connecting portion 100 and the first bracket 430 in this application includes the case where the first connecting portion 100 is directly connected to the first bracket 430, but does not simply mean that the first connecting portion 100 is directly connected to the first bracket 430. It can also be connected through other components, for example, the first connecting portion 100 described later is connected to the first bracket 430 through the flexible support member 300. Similarly, the connection between the second connecting portion 200 and the second bracket 440, as well as the connection between the third connecting portion 500 and the first bracket 430 and the connection between the fourth connecting portion 600 and the second bracket 440 described later can be understood with reference to the connection between the first connecting portion 100 and the first bracket 430.

[0056] like Figure 1-Figure 3 As shown, optionally, the bracket also includes a flexible support member 300, which connects the first bracket 430 and the second bracket 440, and the rigidity of the flexible support member 300 in the first direction is less than that of the first bracket 430 and the second bracket 440, and the flexible support member 300 is connected to the deformation part 720; the root of the first connection part 100 is arranged on the side of the first bracket 430 facing the second bracket 440, and the root of the second connection part 200 is arranged on the side of the second bracket 440 facing the first bracket 430.

[0057] By arranging the first connecting part 100 on the side of the first bracket 430 facing the second bracket 440, and arranging the second connecting part 200 on the side of the second bracket 440 facing the first bracket 430, a force can be applied to the flexible support member 300 at both ends of the length direction of the flexible support member 300 to cause it to deform, thereby more comprehensively constraining the shape of the flexible support member 300, reducing or even eliminating the size of the area where its shape is uncontrolled, and ensuring that the filter body 700 can have the expected shape.

[0058] Furthermore, by connecting the first connecting portion 100 and the second connecting portion 200, the degree of bending of the deformed portion 720 is increased. That is, when the first connecting portion 100 and the second connecting portion 200 are separated, the degree of bending of the deformed portion 720 is smaller. Therefore, the filter assembly is flatter after injection molding than after being assembled and connected with the first connecting portion 100 and the second connecting portion 200. This facilitates the placement of more filter assemblies in a packaging box or container of the same size, increasing the packing rate and improving the efficiency of handling, transportation, and storage of the filter assembly.

[0059] In this embodiment, the first bracket 430 is located at the rear of the bracket, the flexible support member 300 is located at the front of the bracket, and the second bracket 440 is located in front of the flexible support member 300. Since the indoor heat exchanger of a wall-mounted air conditioner indoor unit is generally in an inverted V-shape or an inverted U-shape, this embodiment is described by taking the flexible support member 300 as an example, in which the space between the upper portion of the indoor heat exchanger and the front portion of the middle frame 900 or the air conditioner panel is provided.

[0060] Of course, in another implementation, the flexible support member 300 can also be arranged at the rear of the bracket, and the first bracket 430 can be arranged at the front of the bracket. Alternatively, two sets of flexible support members 300 can be arranged along the front and back of a filter assembly, with the first bracket 430 positioned between the two, and the second bracket 440 positioned at the front and rear of the bracket. In other words, flexible support members 300 can be positioned between the indoor heat exchanger and the rear of the base, and between the indoor heat exchanger and the front of the middle frame 900 or the air conditioning panel, to increase the area of ​​the filter body 700 and improve the filtering effect.

[0061] Specifically, in this embodiment, a plurality of flexible support members 300 are arranged along the left-right direction of the bracket, that is, from one end to the other end of the bracket at the two opposite ends. More specifically, five flexible support members 300 are arranged.

[0062] In this embodiment, the first bracket 430 is composed of first grille bars 410 extending in the left-right direction and second grille bars 420 extending in the front-to-back direction. The second bracket 440 also includes the first grille bars 410. The flexible support member 300 can be in the form of bars or ribs. In this embodiment, the first bracket 430 and the second bracket 440 are not completely indeformable. However, the rigidity of the first bracket 430 and the second bracket 440 is significantly greater than that of the flexible support member 300. When subjected to force, the deformation of the first bracket 430 and the second bracket 440 is significantly less than that of the flexible support member 300. Specifically, in this embodiment, the deformation of the flexible support member 300 is primarily manifested as downward deformation of the flexible support member 300 in a plane perpendicular to the left-right direction due to the shortened front-to-back distance between its ends. This can be achieved by, for example, providing reinforcing ribs on the first and / or second side surfaces of the second grille bars 420 of the first bracket 430 to increase the rigidity of the second grille bars 420 of the first bracket 430 and reduce their deformation. Of course, the first grille bars 410 of the first and second brackets 430, 440 can also be provided with reinforcing ribs on the first and / or second side surfaces to increase their rigidity and reduce their deformation. Of course, the rigidity difference between the first and second brackets 430, 440 and the flexible support member 300 can also be achieved by increasing the material size of the first and second brackets 430, 440.

[0063] The fact that the first fixing portion 710 is fixedly connected to the first bracket 430 obviously does not mean that the entire first fixing portion 710 is fixedly connected to the first bracket 430. Specifically, the area of ​​the fixing portion 710 that opposes the first and second grille bars 410, 420 can be at least partially fixedly connected to the first and second grille bars 410, 420, i.e., the two can be fused together during the bracket's injection molding process. A portion of the first fixing portion 710 also corresponds to the opening between the first and second grille bars 410, 420 of the first bracket 430. This portion is not directly fixedly connected to the first fixing portion 710, ensuring that air can be taken in and filtered through this area. Since the second bracket 440 in this embodiment includes the first grille bars 410, the second fixing portion fixedly connected to the second bracket 440 is also correspondingly narrow, making it difficult to directly illustrate in the figure that the second fixing portion is partially or entirely fixedly connected to the second bracket 440.

[0064] Furthermore, the first grid bars 410 can be disposed not only within the first bracket 430 but also connected to the flexible support member 300. For example, as described below, the first thinned region 310 and the second thinned region 320 can both be directly connected to the first grid bars 410. Accordingly, each flexible support member 300 can also transmit forces through the first grid bars 410. Therefore, by providing the first connecting portion 100 and the second connecting portion 200 corresponding to a portion of the flexible support member 300, and by connecting the first connecting portion 100 and the second connecting portion 200 to deform the flexible support member 300, each flexible support member 300 can transmit forces through the first grid bars 410, driving the deformation of other flexible support members 300 to achieve a curved bracket shape that approximates the desired shape. In other words, there is no need to provide corresponding first connecting portions 100 and second connecting portions 200 for each flexible support member 300 to deform the flexible support member 300.

[0065] In this embodiment, the first connecting portion 100 is mounted on a first bracket 430, while the second connecting portion 200 is mounted on a second bracket 440. The first bracket 430 includes first and second grille bars 410 and 420 that intersect vertically and horizontally. The first bracket 430 is more rigid than the second bracket 440. This arrangement offers advantages when bending or rotating the second connecting portion 200. Because the base of the second connecting portion 200 is not connected to the more rigid first bracket 430, the bending and swinging of the second connecting portion 200 is more flexible. Alternatively, the second connecting portion 200 may be closer to the first bracket 430 than the first connecting portion 100.

[0066] Specifically, in this embodiment, the roots of the first connection part 100 and the second connection part 200 can be directly connected to the second grid bars 420 at both ends of the flexible support part 300 in the length direction, and the roots of the first connection part 100 and the second connection part 200 are respectively connected to the two ends of the flexible support part 300 in the length direction.

[0067] Of course, in another implementation, the first connection portion 100 and the second connection portion 200 can also be arranged on both end surfaces of the bracket, i.e., the left and right end surfaces. Specifically, the two can form the middle region of the two arms of the flexible support member 300, which is roughly U-shaped after deformation, so that the flexible support member 300, the first connection portion 100, and the second connection portion 200 form an inverted A shape. This can also make the flexible support member 300 have a shape that is closer to the desired shape, but the fixing effect is not as ideal as when it is arranged on the second side surface.

[0068] Furthermore, in other implementations, the flexible support member 300 may not be provided. This is because the deformable portion 720 of the filter body 700 itself has the ability to rebound after bending. After the deformable portion 720 bends downward, it has the ability to spontaneously deform to a flatter state. Therefore, the deformable portion 720 can also form a relatively smooth curved surface after bending, and the flexible support member 300 is not absolutely required to control the shape of the deformable portion 720.

[0069] like Figure 1-Figure 3 As shown, optionally, the first connecting portion 100 is located at both ends of the first bracket 430 ; the second connecting portion 200 is located at both ends of the second bracket 440 .

[0070] By placing the first connecting portion 100 at both ends of the first bracket 430 and the second connecting portion 200 at both ends of the second bracket 440, the deformation of the flexible support members 300 located at both ends of the brackets can be controlled. Simultaneously, utilizing the first grille bars 410 extending in the left-right direction, which connect the two ends of each of the first and second brackets 430 and 440, the deformation of multiple flexible support members 300 arranged side by side can be controlled. This improves the deformation consistency of each flexible support member 300 and the shape consistency of the filter body 700. When the filter assembly is installed in a wall-mounted air conditioner indoor unit, interference with the heat exchanger can be avoided.

[0071] Of course, in another implementation, the first connection part 100 and the second connection part 200 may not be arranged at the left and right ends of the bracket. For example, taking the arrangement of five flexible support members 300 in the left and right directions of the bracket in this embodiment as an example, the first connection part 100 and the second connection part 200 are arranged above the second and fourth flexible support members 300, which can not only deform the second and fourth flexible support members 300, but also control the deformation of the third flexible support member 300 between the second and fourth. It also has a control effect on the first and fifth flexible support members 300 at the very end. However, due to the influence of the stiffness of the first grid bar 410, the first and fifth flexible support members 300 may not be as deformed as the second and fourth flexible support members 300.

[0072] Figure 4 This is a schematic structural diagram of the filter assembly provided in Example 1 of the present invention in another direction after the injection molding process is completed; Figure 5 This is a schematic structural diagram of the bracket in the filter assembly provided in the first embodiment of the present invention as viewed from another direction; Figure 6 This is a schematic structural diagram of the bracket in the filter assembly provided in the first embodiment of the present invention as viewed from another direction; Figure 7This is a schematic structural diagram of the filter assembly provided in Example 1 of the present invention in another direction after the injection molding process is completed; Figure 3-Figure 7 As shown, optionally, the first connecting part 100 has a first accommodating space 110, and the second connecting part 200 has a first plug-in part 210, and the accommodating space is used to accommodate the first plug-in part 210; when the bending degree of the deformation part 720 decreases, the movement direction of the second connecting part 200 relative to the first connecting part 100 is the first direction, and a side wall of the first accommodating space 110 in the first direction constitutes a first check portion 111, and a side surface of the first plug-in part 210 in the first direction constitutes a second check portion 211, and the first check portion 111 cooperates with the second check portion 211.

[0073] By forming a first non-return portion 111 on the sidewall in the first direction of the first accommodating space 110 and a second non-return portion 211 on the surface in the first direction of the first plug-in portion 210 of the second connecting portion 200, the first non-return portion 111 and the second non-return portion 211 cooperate to prevent the first plug-in portion 210 from being removed from the first accommodating space 110 in the first direction. Therefore, after the injection molding is completed and the first plug-in portion 210 is inserted into the first accommodating space 110, the deformable portion 720 is forced to bend concavely and maintain a stable state, thereby obtaining the desired concave filter assembly.

[0074] Specifically, in this embodiment, the first check portion 111 and the second check portion 211 can be perpendicular to the first direction, or can be set at an acute angle to the first direction. The cotangent value of the acute angle is less than the friction coefficient between the two surfaces of the bracket material, and can also prevent the first plug-in portion 210 from escaping from the first accommodating space 110 along the first direction. That is, when the deformation portion 720 returns to its original shape, it will generate a pulling force on the first connection portion 100 and the second connection portion 200 to pull the first plug-in portion 210 out of the first accommodating space 110. When the surfaces of the first check portion 111 and the second check portion 211 are perpendicular to the first direction, or are at the above-mentioned acute angle, the relative movement of the first check portion 111 and the second check portion 211 can be directly blocked, or the friction force generated by the contact pressure between the two can be used to prevent the relative movement between the two. Therefore, after the first plug-in portion 210 is inserted into the first accommodating space 110, in a spontaneous state, the first connection portion 100 and the second connection portion 200 cannot be separated simply by the deformation portion 720 returning to its original shape.

[0075] like Figure 3-Figure 7 As shown, optionally, the first connecting portion 100 includes a first upper side wall 112 and a first lower side wall 113 opposite to each other, and the first upper side wall 112 and the first lower side wall 113 form a first receiving space 110 .

[0076] By setting the first upper side wall 112 and the first lower side wall 113 to form the first accommodating space 110, the first plug-in part 210 can be limited in the up and down directions. When the first plug-in part 210 is inserted into the first accommodating space 110 and the filter assembly forms its final shape, the force in the up and down directions accidentally acting on the second connecting part 200 can be avoided, causing the first connecting part 100 to fall out of the first accommodating space 110.

[0077] Among them, taking the filter assembly applied to a wall-mounted air-conditioning indoor unit as an example, the filter assembly is placed roughly horizontally, and the first upper side wall 112 and the first upper side wall 112 are both flat and parallel, and are both horizontal or nearly horizontal.

[0078] like Figure 3-Figure 7 As shown, optionally, the first connecting part 100 is located at both ends of the first bracket 430; the second connecting part 200 is located at both ends of the second bracket 440; the first accommodating space 110 is open in a direction away from the middle of the bracket, and the middle of the bracket is the central area of ​​the bracket at the line connecting the two first connecting parts 100.

[0079] The first connecting portion 100 is disposed at both ends of the first bracket 430, and the second connecting portion 200 is disposed at both ends of the second bracket 440, so that the first accommodating space 110 opens in a direction away from the center of the bracket. After the filter assembly is installed in the air inlet 910 of the wall-mounted air conditioner indoor unit, the sidewalls of the air inlet 910 can be used to block the first plug-in portion 210 from moving away from the center of the bracket, thereby preventing the filter assembly from being removed from the opening of the first accommodating space 110 after installation, thereby ensuring normal operation of the wall-mounted air conditioner indoor unit. When the filter assembly is removed from the middle frame 900, the second connecting portion 200 can swing away from the center of the bracket, that is, swing outward. This allows the first plug-in portion 210 to easily disengage from the first accommodating space 110, releasing the connection between the first connecting portion 100 and the second connecting portion 200, thereby allowing the deformable portion 720 to unfold, facilitating cleaning of the filter body 700.

[0080] In this embodiment, the first accommodating space 110 also has a first horizontal side wall 114, which is in a vertical state and connects the first upper side wall 112 and the first lower side wall 113. Therefore, the side wall cross-section around the first accommodating space 110 is in a door shape rotated 90°, and the opening of the door shape is away from the middle of the bracket.

[0081] In another implementation, the first receiving space 110 can be a circumferentially closed space, while the first plug-in portion 210 can be wedge-shaped. Once the first plug-in portion 210 is inserted into the first receiving space 110, it cannot be removed or is difficult to remove. Although this solution is not as convenient to operate, especially during use, as in the present embodiment, it can also allow the bracket to be injection molded in a straighter, less curved state, allowing the filter body 700 to be laid in place, thereby improving the connection quality between the filter body 700 and the bracket.

[0082] like Figure 3-Figure 7 As shown, optionally, the opposite direction of the first direction is the second direction; the first connecting portion 100 also has a first guide space 120, the first guide space 120 is connected to the first accommodating space 110, and the side wall of the first guide space 120 in the second direction constitutes a first guide portion 121; the first plug-in portion 210 constitutes a second guide portion 212 on a side surface in the second direction, and the first guide portion 121 cooperates with the second guide portion 212.

[0083] By setting a first guide portion 121 on the side wall of the first guide space 120 in the second direction, and cooperating with setting a second guide portion 212 on the first plug-in portion 210, when the first guide portion 121 passes through the first guide space 120 and moves toward the first accommodating space 110, the first guide portion 121 and the second guide portion 212 can be used to cooperate with each other to squeeze each other, so that the second connection portion 200 is offset outward and the first connection portion 100 is offset inward. The connection between the first connection portion 100 and the second connection portion 200 can be achieved only by the plug-in action, thereby improving operational efficiency.

[0084] Moreover, during use, even if the user does not follow the method of first connecting the first connecting part 100 with the second connecting part 200 and then installing the filter assembly back into the air-conditioning indoor unit after cleaning the filter assembly, but first installs part of the filter assembly into the air-conditioning indoor unit and then connects the first connecting part 100 with the second connecting part 200, the user can also forcefully push the first plug-in part 210 along the second direction, and utilize the action between the first guide part 121 and the second guide part 212 to make the first connecting part 100 shift inward, or send the first plug-in part 210 into the first accommodating space 110, thereby reducing the degree of restriction on the user's operation and making it easier for the user to clean the filter assembly.

[0085] Specifically, in this embodiment, a protrusion is formed on the first horizontal sidewall 114 between the first accommodating space 110 and the first guide space 120. The protrusion may be trapezoidal in shape when viewed from above. The side of the protrusion facing the first accommodating space 110, i.e., the side of the protrusion facing the second direction, is the first check portion 111. The side of the protrusion facing the first guide space 120, i.e., the side of the protrusion facing the first direction, is the first guide portion 121.

[0086] The angle between the first guide portion 121 and the first direction is an acute angle, and is smaller than the acute angle between the first check portion 111 and the first direction. More specifically, for example, the acute angle between the first guide portion 121 and the first direction can be less than or equal to 20°, or the tangent value of the acute angle between the first guide portion 121 and the first direction can be smaller than the friction coefficient between the two surfaces both of which are bracket materials.

[0087] In addition to the first plug-in portion 210, the second connecting portion 200 also includes a first connecting rod portion 220 and a mating root portion 230. The mating root portion 230 can be stepped, and the first guide space 120 can also have a stepped structure to mate with the mating root portion 230 of the second connecting portion 200 to absorb vertical forces. The first connecting rod portion 220 connects the first plug-in portion 210 and the mating root portion 230. The mating root portion 230 is directly connected to the first grille bar 410.

[0088] like Figure 3-Figure 7 As shown, optionally, the first guide space 120 also has an opening direction consistent with that of the first accommodating space 110 .

[0089] The first guide space 120 is set to open in a direction away from the middle of the bracket. When the user is cleaning the filter assembly, after the filter assembly is removed from the air-conditioning indoor unit, the second connection part 200 can be swung away from the middle of the bracket to release the connection between the second connection part 200 and the first connection part 100, thereby improving the convenience of user operation.

[0090] It should be noted that the opening direction of the first guide space 120 is consistent with that of the first accommodating space 110. This does not necessarily mean that all openings of the first guide space 120 are consistent with the opening direction of the first accommodating space 110. Rather, the first guide space 120 may also have openings in the direction consistent with the opening of the first accommodating space 110. For example, in this embodiment, a portion of the first guide space 120 may also open upward, that is, in addition to the opening direction of the first accommodating space 110, the first guide space 120 may also have openings in other directions.

[0091] Optionally, the bracket also includes a third connecting part 500 and a fourth connecting part 600, and the third connecting part 500 and the fourth connecting part 600 are located in the middle of the bracket, the third connecting part 500 is connected to the first bracket 430, and the fourth connecting part 600 is connected to the second bracket 440; in the connected state, the third connecting part 500 and the fourth connecting part 600 are connected, and in the separated state, the third connecting part 500 and the fourth connecting part 600 are separated.

[0092] Since the first connecting portion 100 is disposed at both ends of the first bracket 430 and the second connecting portion 200 is disposed at both ends of the second bracket 440, the flexible support members 300 at both ends of the bracket are directly deformed and stabilized in a bent state. However, the flexible support members 300 at the rest of the bracket require force transmission from other components to deform and stabilize them in a bent state. Therefore, a third connecting portion 500 and a fourth connecting portion 600 are disposed in the middle of the bracket. When the third connecting portion 500 and the fourth connecting portion 600 are connected, they can directly pull the flexible support member 300 located in the middle of the bracket to deform, thereby driving the filter body 700 to form a bent shape. Moreover, the deformation effect of the adjacent flexible support member 300 can be enhanced, so that the filter body 700 as a whole is closer to the expected bent shape.

[0093] In this embodiment, the third connecting portion 500 is closer to the first bracket 430 than the fourth connecting portion 600. This arrangement is advantageous when the fourth connecting portion 600 needs to be bent or rotated left or right, because the base of the fourth connecting portion 600 is not connected to the more rigid first bracket 430, allowing for greater flexibility in bending and swinging of the fourth connecting portion 600. Of course, in other implementations, the fourth connecting portion 600 may also be closer to the first bracket 430 than the third connecting portion 500.

[0094] like Figure 3-Figure 7 As shown, optionally, the third connection part 500 has a second accommodating space 510, and the fourth connection part 600 has a second plug-in part 610, and the second accommodating space 510 is used to accommodate the second plug-in part 610; when the bending degree of the deformation part 720 is reduced, the movement direction of the fourth connection part 600 relative to the third connection part 500 is the first direction, and the second accommodating space 510 constitutes a third check portion 511 on one side of the first direction, and the second plug-in part 610 constitutes a fourth check portion 611 on one side of the first direction, and the third check portion 511 cooperates with the fourth check portion 611.

[0095] By utilizing the sidewall of the second accommodating space 510 in the first direction to form the third check portion 511, and utilizing the surface of the second plug-in portion 610 of the fourth connecting portion 600 in the first direction to form the fourth check portion 611, the third check portion 511 and the fourth check portion 611 cooperate to prevent the second plug-in portion 610 from escaping from the second accommodating space 510 in the first direction. Consequently, after injection molding is completed and the second plug-in portion 610 is inserted into the second accommodating space 510, the filter assembly, after the deformed portion 720 has been deformed, does not need to be immediately installed in the air conditioner indoor unit. In other words, once the second plug-in portion 610 is inserted into the second accommodating space 510, the deformed portion 720 is forced to bend downward and maintain a stable state, thereby achieving the desired concave filter assembly.

[0096] Specifically, in this embodiment, the third check portion 511 and the fourth check portion 611 can be perpendicular to the first direction, or can be set at an acute angle to the first direction. The cotangent value of the acute angle is less than the friction coefficient between the two surfaces of the bracket material, and can also prevent the second plug-in portion 610 from escaping from the second accommodating space 510 along the first direction. That is, when the deformation portion 720 returns to its original shape, it will generate a pulling force on the third connection portion 500 and the fourth connection portion 600 to pull the second plug-in portion 610 out of the second accommodating space 510. When the surfaces of the third check portion 511 and the fourth check portion 611 are perpendicular to the first direction, or are at the above-mentioned acute angle, they can directly block the relative movement of the first check portion 111 and the fourth check portion 611, or use the friction force generated by the contact pressure between the two to prevent the relative movement between the two. Therefore, after the second plug-in portion 610 is inserted into the second accommodating space 510, in a spontaneous state, the third connection portion 500 and the fourth connection portion 600 cannot be separated simply by the deformation portion 720 returning to its original shape.

[0097] In this embodiment, the second accommodating space 510 is provided with an opening on one side facing the first side, and a side wall of the opening facing the first direction is a third non-return portion 511. The fourth non-return portion 611 of the second plug-in portion 610 abuts against the third non-return portion 511, that is, abuts against the side wall of the opening facing the first direction.

[0098] like Figure 4-Figure 7 As shown, optionally, the second accommodating space 510 opens toward the first connecting portion 100 .

[0099] The second accommodating space 510 is opened toward the first connecting part 100. When the user cleans the filter assembly, since the flexible support member 300 itself is not very rigid, the fourth connecting part 600 can be swung toward the first connecting part 100 to disengage the second plug-in part 610 from the second accommodating space 510, thereby releasing the connection between the third connecting part 500 and the fourth connecting part 600, thereby expanding the deformation part 720 to facilitate cleaning of the filter body 700.

[0100] Specifically, in this embodiment, the cross section of the side wall of the second accommodating space 510 is an inverted L-shape within a partial length range of the second accommodating space 510 , and is a U-shape rotated 90° within another partial length range.

[0101] like Figure 4-Figure 7 As shown, optionally, the third connecting portion 500 further has a second guide space 520 , which is communicated with the second accommodating space 510 , and an opening direction of the second guide space 520 is consistent with that of the second accommodating space 510 .

[0102] The opening direction of the second guide space 520 is set to be consistent with the second accommodating space 510. When the user cleans the filter assembly, after the filter assembly is removed from the air-conditioning indoor unit, the fourth connection part 600 can be swung toward the first connection part 100 to release the connection between the fourth connection part 600 and the third connection part 500, thereby improving the convenience of user operation.

[0103] Among them, the cross-section of the second guide space 520 perpendicular to the first direction is a U-shape or door-shape rotated 90°. This structure prevents the third connecting part 500 from escaping from the third accommodating space due to the force in the up and down directions acting on the fourth connecting part 600 accidentally after the third plug-in part is inserted into the third accommodating space and the filter assembly forms its final shape.

[0104] Optionally, the flexible support member 300 has a thinned region, and the thinned region includes a first thinned region 310 located in the middle of the flexible support member 300 in the longitudinal direction.

[0105] By providing a thinned region, the stiffness of the thinned region is lower than the stiffness of the flexible support member 300 outside the thinned region. Therefore, when the flexible support member 300 is subjected to force, the deformation of the thinned region is significantly greater than that of the non-thinned region, which helps control the deformation position of the flexible support member 300. Furthermore, by providing a first thinned region 310 in the middle of the length direction of the flexible support member 300, the first thinned region 310 can be used to form the angled portion where the two arms of the concave portion of the flexible support member 300 connect, thereby controlling the maximum deformation position of the flexible support member 300 and reducing the deformation stress of the flexible support member 300.

[0106] Among them, the first thinning area 310 on each flexible support member 300 can be a whole continuous thinning area, or it can be a multi-segment thinning area. The multi-segment thinning area makes the first thinning area 310 of the flexible support member 300 form a rack shape, which can also play a role in reducing local stiffness and controlling the position with greater deformation to be the first thinning area 310.

[0107] like Figure 1-Figure 3 and Figure 5 、 Figure 6 As shown, optionally, the thinned area includes a second thinned area 320 located at the end of the flexible support member 300 in the length direction.

[0108] A second thinning zone 320 is provided at the end of the flexible support member 300 in the longitudinal direction, so that the stiffness of the end of the flexible support member 300 in the longitudinal direction can be reduced, which is beneficial for deforming the flexible support member 300 relative to the parts connected thereto, so as to control the deformation position of the flexible support member 300 and reduce the deformation stress of the flexible support member 300.

[0109] In this embodiment, second thinned regions 320 are provided at both ends of the lengthwise direction of the flexible support member 300. Similarly, the second thinned region 320 can be a single continuous thinned region or a plurality of thinned regions spaced apart. The plurality of thinned regions spaced apart allows the second thinned regions 320 of the flexible support member 300 to form a rack shape, which can also reduce local stiffness and control the location of greater deformation to the second thinned region 320.

[0110] like Figure 1-Figure 3 and Figure 5 、 Figure 6 As shown, optionally, the first side surface of the first thinning region 310 is thinned and recessed or the surface of the first thinning region 310 facing away from the first side surface is thinned and recessed; and / or,

[0111] The first side surface of the second thinning region 320 is thinned and recessed, or the surface of the second thinning region 320 facing away from the first side surface is thinned and recessed.

[0112] The first side surface of the first thinning zone 310 is thinned and recessed. When the first thinning zone 310 and the adjacent areas solidify, the materials in the adjacent areas will gradually converge and bend toward the surface of the first thinning zone 310 that is opposite to the first side surface, so that a shape recessed toward the opposite side of the first side surface can be formed in the first thinning zone 310. This is beneficial for aggravating the bulge of the first side surface when pressure is applied to both ends of the flexible support member 300, thereby forming a desired deformation direction.

[0113] When the first thinned area 310 bends, the surface facing away from the first side surface is concave and subject to greater pressure. Thinning and concave the surface of the first thinned area 310 can reduce the amount of material on the surface of the first thinned area 310, thereby reducing the degree of pressure on the material and reducing the possibility of excessive pressure causing fracturing.

[0114] The surface of the second thinning zone 320 facing away from the first side surface is thinned and recessed. When the second thinning zone 320 and the adjacent area solidify, the materials in the adjacent area will gradually converge and bend toward the first side surface of the second thinning zone 320, so that a shape recessed toward the second side surface can be formed in the second thinning zone 320. This is beneficial for the area of ​​the flexible support member 300 adjacent to the second thinning zone 320 to deform in the direction of causing the first thinning zone 310 to bulge toward the first side surface when pressure is applied to both ends of the flexible support member 300, thereby forming a desired deformation direction.

[0115] When the first side surface of the second thinned region 320 is bent, it is concave and subjected to significant pressure. Thinning and concave the surface of the second thinned region 320 can reduce the amount of material on the surface of the second thinned region 320, thereby reducing the degree of pressure on the material and reducing the possibility of excessive pressure causing fracturing.

[0116] In this embodiment, a combination of the second side thinning recesses of the first thinning region 310 and the second thinning region 320 is used, that is, the surface thinning recesses facing away from the first side of the first thinning region 310 and the second thinning region 320 are used. In other implementations, the first side thinning recesses of the first thinning region 310 and the second side thinning recesses of the second thinning region 320 may be used, or the first side thinning recesses of the first thinning region 310 and the second side thinning recesses of the second thinning region 320 may be used, or a combination of the second side thinning recesses of the first thinning region 310 and the first side thinning recesses of the second thinning region 320 may be used. All of these can achieve corresponding effects.

[0117] The operating principle of this embodiment is:

[0118] Taking the filter assembly used in a wall-mounted air conditioner indoor unit as an example, the filter assembly undergoes the following manufacturing process:

[0119] First, the filter body 700 is placed on the lower mold. Because the bend angle of the filter body 700 is small or not bent before injection molding begins, the filter body 700 can fit relatively tightly against the lower mold. The mold is then closed and liquid plastic is injected. The higher temperature of the liquid plastic partially melts the filter body 700, and when it solidifies, the bracket can fuse with the filter body 700. Because the filter body 700 fits tightly against the lower mold, the parts where the bracket is expected to contact the filter body 700 can be tightly connected to the filter body 700, avoiding gaps or holes between the two, which would affect the product yield.

[0120] After the stent is completely solidified and demolded, the flexible support member 300 of the stent will not remain completely straight in its natural state due to the thinning depressions of the first thinning area 310 and the second thinning area 320. In this embodiment, on each flexible support member 300, there are two second thinning areas 320, while there is only one first thinning area 310. The thinning depression of the second thinning area 320 causes this area to bulge upward. Therefore, when the first connecting portion 100 and the second connecting portion 200 are connected, a deforming force is applied to the deformation zone. The upward bulging action of these two parts causes the first thinning area 310 to bulge downward without causing reverse deformation.

[0121] During the connection between the first connecting portion 100 and the second connecting portion 200, i.e., when the first connecting portion 100 and the second connecting portion 200 switch from a disconnected state to a connected state, the first plug-in portion 210 enters the first guide space 120, and the first guide portion 121 contacts the second guide portion 212. This contact causes the first connecting portion 100 to swing inward toward the center of the bracket, and / or the second connecting portion 200 to swing outward away from the center of the bracket. After the first plug-in portion 210 fully enters the first accommodating space 110, the first connecting portion 100 and the second connecting portion 200 return to their original shapes.

[0122] Similarly, during the process of forming a connection between the third connecting part 500 and the fourth connecting part 600, the second plug-in part 610 can swing into the second accommodating space 510, or the fourth connecting part 600 can be elastically deformed in the height direction, so that the second plug-in part 610 passes through the second guide space 520 along the length direction of the second guide space 520 and enters the second accommodating space 510.

[0123] Due to the cooperative non-return effect of the first non-return portion 111 and the second non-return portion 211, as well as the non-return effect of the third non-return portion 511 and the fourth non-return portion 611, after the filter assembly is formed and before being placed in the air-conditioning indoor unit, the connection between the first connection portion 100 and the second connection portion 200, and the connection between the third connection portion 500 and the fourth connection portion 600 cannot be opened by simply relying on the force of the flexible support member 300 to restore its original shape, thereby facilitating the separation of the step of forming the filter assembly from the step of assembling the filter assembly in the air-conditioning indoor unit.

[0124] After the user cleans the filter assembly and removes it from the air conditioner indoor unit, the user can swing the second connection part 200 outward, i.e., away from the center of the bracket, to release the connection between the first connection part 100 and the second connection part 200. Furthermore, the user can swing the fourth connection part 600 toward the first connection part 100 to release the connection between the third connection part 500 and the fourth connection part 600. This significantly reduces the degree of bending of the filter body 700 and even makes the filter body 700 roughly flat, making it easier to clean the filter body 700. After cleaning is completed, the filter assembly can be installed back into the air conditioner indoor unit according to the same assembly process.
