Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a filter screen assembly and an air conditioner. BACKGROUND

[0002] The middle frame is an indispensable component of an air conditioner, which is used to accommodate an indoor heat exchanger and set an air inlet to introduce air for heat exchange. For a wall-mounted air conditioner indoor unit, the air inlet is usually located at the top of the middle frame. A filter screen assembly is generally arranged at the air inlet to filter the incoming air, block dust and other foreign matters in the air, and reduce the accumulation of dust on the indoor heat exchanger, so as to ensure the heat exchange efficiency of the indoor heat exchanger.

[0003] Although part of the prior art sets the filter screen body of the filter screen assembly into a downwardly recessed shape to increase the contact area of the airflow with the filter screen body, improve the filtering effect, and uses a bracket provided with a longitudinal rib plate as a skeleton of the filter screen body to support the filter screen body. However, the filter screen assembly in the above form needs to first lay the filter screen body in the deep groove of the lower mold during the manufacturing process of the filter screen assembly. Since the filter screen body itself has elasticity, the filter screen body is not easy to lay flat, which may result in that the bracket and the filter screen body cannot be completely and tightly attached during the injection molding process of the bracket, and the manufactured filter screen assembly may have a situation that part of the edges of the filter screen body are separated from the bracket, causing injection molding manufacturing defects of the filter screen assembly and high production rejection rate. SUMMARY

[0004] The first object of the present application is to provide a filter screen assembly to solve the technical problems of possible local separation of the filter screen body and the bracket, injection molding manufacturing defects of the filter screen assembly, and high production rejection rate.

[0005] The filter screen assembly provided by the present application comprises a bracket and a filter screen body, the bracket comprises a first bracket and a second bracket arranged at intervals, the filter screen body comprises a first fixed part fixedly connected to the first bracket, a second fixed part fixedly connected to the second bracket, and a deformation part connecting the first fixed part and the second fixed part, the first fixed part, the deformation part and the second fixed part are arranged in sequence along a first direction; the second bracket is provided with a first retreat stop part for abutting against a second retreat stop part arranged on the middle frame to prevent the second bracket from moving away from the first bracket along the first direction; the deformation part is configured to increase the bending and protruding degree of the deformation part along the air inlet direction when the distance between the first bracket and the second bracket is reduced.

[0006] The filter screen assembly provided by the present application has the following beneficial effects:

[0007] By setting the first support and the second support corresponding to the first fixed part and the second fixed part respectively, and the first support and the second support can be reduced in distance, so as to realize the bending and protruding degree of the deformation part connected between the first fixed part and the second fixed part along the air inlet direction. Thus, during the support injection molding process, the deformation part is in a state of smaller bending and protruding degree, or even in a flat state. Before injection molding, the filter screen body can be laid on a relatively flat surface, and the filter screen body can be more closely attached to the mold. That is, the attachment of the filter screen body and the mold is not affected by the bending of the filter screen body in the finished state. Then, during the injection process, among the various parts of the support, the area that needs to be closely combined with the filter screen body can be better combined with the filter screen body, thereby improving the yield, and also improving the reliability of the air conditioner filter screen assembly during use, avoiding the leakage of part of the air from the filter screen body and the support into the air conditioner to pollute the indoor heat exchanger. After the injection is completed, the first support is inserted into the middle frame, and the second support is continuously pushed to increase the bending and protruding degree of the deformation part, and then the first stop part and the second stop part on the middle frame are abutted to prevent the second support from moving away from the first support, so that the deformation part can maintain the shape of protruding along the air inlet direction, and will not be opened under the restoring force of the deformation part.

[0008] In an optional technical solution, the support further comprises a flexible support member connected to the first support and the second support, the rigidity of the flexible support member in the first direction is less than that of the first support and the second support, and the flexible support member is fixedly connected to the deformation part.

[0009] Although the rigidity of the flexible support member connecting the first support and the second support is less than that of the first support and the second support, its rigidity is obviously greater than that of the deformation part of the filter screen body. After the first support and the second support are close, the deformation part is bent and protruded along the air inlet direction, and the shape of the deformation part can be maintained by the rigidity of the flexible support member, thereby ensuring the overall shape and filtering effect of the deformation part.

[0010] In an optional technical solution, the filter screen assembly is configured to be installed in a middle frame, the first support is configured to abut a guide structure of the middle frame in a direction perpendicular to the first direction, and the first support is configured to be in sliding friction connection with the guide structure.

[0011] By setting the first support to be in sliding friction connection with the guide structure, resistance can be generated during the deepening of the first support into the middle frame, and the second support is continuously pushed. When the deformation part and the flexible support member cannot transmit the force of the second support, the deformation part and the flexible support member will be bent, so as to form the expected bending and protruding shape of the deformation part and the flexible support in the air inlet direction during the installation of the filter screen assembly to the middle frame, thereby improving the operation efficiency.

[0012] In an optional technical solution, the opposite end faces of the first support are provided with first protrusions, and / or the surface of the first support in the second direction is provided with first ridges.

[0013] By providing the first protrusions on the opposite end faces of the first support and / or the first ridges on the surface of the first support in the second direction, the first support can abut against the guide structure, thereby increasing the friction between the first support and the guide structure.

[0014] In an optional technical solution, the surface of the first retreat-preventing portion facing the third direction forms a first guide surface, and / or the surface of the second retreat-preventing portion facing the first direction forms a second guide surface, the third direction being opposite to the first direction.

[0015] By providing the first guide surface and / or the second guide surface, the first retreat-preventing portion can be guided when it contacts the second retreat-preventing portion by the cooperation of the first guide surface and the second guide surface. This facilitates the extrusion of the first retreat-preventing portion downward, so that the first retreat-preventing portion can pass over the second retreat-preventing portion, thereby facilitating the installation of the filter screen assembly.

[0016] In an optional technical solution, the second support is provided with a pressing portion, and the pressing portion and the first retreat-preventing portion are arranged in the first direction.

[0017] By providing the pressing portion, when it is necessary to detach the filter screen assembly from the middle frame for cleaning, the pressing portion can be pressed to make the first retreat-preventing portion and the second retreat-preventing portion disengage, thereby releasing the locking of the first retreat-preventing portion by the second retreat-preventing portion, so as to facilitate the disassembly of the filter screen assembly and improve the use convenience of the filter screen assembly.

[0018] In an optional technical solution, the second support includes first grid bars arranged side by side, the first grid bars extend in the first direction, and the pressing portion protrudes from the first grid bars in a second direction; and / or the pressing portion connects adjacent first grid bars.

[0019] The pressing portion is arranged to protrude from the first grid bars in the second direction, so as to reduce the height difference between the surface of the pressing portion and the region of the third support of the middle frame where the second retreat-preventing portion is arranged. This facilitates the pressing of the pressing portion by the user's finger when the filter screen assembly is detached. Since the second retreat-preventing portion is arranged opposite to the first retreat-preventing portion, the pressing portion is arranged to connect adjacent first grid bars, and the part of the pressing portion connected to the first grid bars is located at a relatively large distance from the second retreat-preventing portion. This facilitates the pressing of the pressing portion by the user's finger and improves the convenience during disassembly.

[0020] In an optional technical solution, the second support is further provided with a third retreat-preventing portion, the third retreat-preventing portion protrudes from the second support in a fourth direction, and the third retreat-preventing portion is used for abutting against the middle frame.

[0021] By setting the third retreat prevention part protruding in the fourth direction on the second support to abut against the middle frame, in the case that the pressing part is accidentally pressed and the retreat prevention function of the second retreat prevention part to the first retreat prevention part is lost, the third retreat prevention part is used to abut against the middle frame to prevent the second support from moving away from the first support, thereby ensuring normal use of the filter screen assembly.

[0022] In the optional technical solution, the flexible support has a thinning area, which includes a first thinning area located in the middle of the length direction of the flexible support and / or a second thinning area located at the end of the length direction of the flexible support.

[0023] By setting the thinning area, since the rigidity of the thinning area is smaller than that of the local part of the flexible support outside the thinning area, when the flexible support is stressed, the deformation of the thinning area is obviously larger than that of the non-thinning area, which is beneficial to control the deformation position of the flexible support. By setting the first thinning area in the middle of the length direction of the flexible support, the first thinning area can be used to form a fold angle part connecting two arms of the recess of the flexible support, so as to control the maximum deformation position of the flexible support and reduce the deformation stress of the flexible support.

[0024] The second object of the present application is to provide an air conditioner to solve the technical problem that the filter screen body and the support may be partially separated to cause filter screen assembly injection molding manufacturing defects and high production scrap rate.

[0025] The air conditioner provided by the present application comprises a middle frame and the filter screen assembly of any one of the above, the middle frame is provided with an air inlet, the filter screen assembly is installed in the air inlet, the air inlet is provided with a third support, and the third support is provided with the second retreat prevention part.

[0026] By setting the filter screen assembly in the air conditioner, the air conditioner has all the advantages of the filter screen assembly, which will not be described here. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0050] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0051] Before introducing the specific embodiments of the present application, the meanings of the directions or orientations in the present application will be explained. In the present embodiments, the filter screen assembly is applied to a wall-mounted air conditioner indoor unit as an example for introduction, but this does not hinder the products of the present application from being applied to a cabinet-type air conditioner indoor unit or a ceiling machine. Of course, in addition to air conditioners, the filter screen assembly can also be applied to other devices or electrical appliances that require air intake, such as air purifiers and bladeless fans, etc.

[0052] Generally, the air inlet 570 of the wall-mounted air conditioner indoor unit is mostly arranged at the top of the wall-mounted air conditioner indoor unit. In the present application, the directions are defined as follows: the front refers to the side of the wall-mounted air conditioner indoor unit facing the main indoor space, and the rear refers to the side of the wall-mounted air conditioner indoor unit facing the wall on which it is hung. The lower refers to the side of the wall-mounted air conditioner indoor unit facing the ground. Correspondingly, the upper refers to the side of the wall-mounted air conditioner indoor unit facing the ceiling. The left and right can be defined based on the front, rear and lower as described above, i.e., when an observer faces the wall on which the wall-mounted air conditioner is installed, the left hand direction of the observer is the left side, and the right hand direction of the observer is the right side.

[0053] In the embodiment, the opposite end faces of the bracket or the first bracket 100 or the second bracket 200 to be described later refer to the left and right end faces of the bracket or the first bracket 100 or the second bracket 200 when the filter screen assembly is installed in the wall-mounted air conditioner indoor unit, and the first side face of the bracket refers to the lower surface of the bracket, and correspondingly, the second side face refers to the upper surface of the bracket. That is, the first side face is the lower surface of the bracket, and the second side face is the upper surface of the bracket. Figures 1-2 and Figure 3 the downward surface of the bracket shown in the drawing and the upward surface of the bracket shown in the drawing, and the second side face is the upward surface of the bracket shown in the drawing and the downward surface of the bracket shown in the drawing. The length direction of the flexible support 300 to be described later is the front-rear direction, that is, the extension direction of the second grid bars 120. When the upper surface of the filter screen assembly is installed as a whole in a horizontal direction, the first direction is the rear-to-front direction, and the second direction is the front-to-rear direction.

As Figures 1-5 shown, the filter screen assembly provided by the embodiment I of the present application comprises a bracket and a filter screen body 400, the bracket comprises a first bracket 100 and a second bracket 200 arranged at intervals, the filter screen body 400 comprises a first fixed part 410 fixedly connected to the first bracket 100, a second fixed part 420 fixedly connected to the second bracket 200, and a deformation part 430 connecting the first fixed part 410 and the second fixed part 420, the first fixed part 410, the deformation part 430 and the second fixed part 420 are arranged in sequence along a first direction; the second bracket 200 is provided with a first retreat-preventing part 210, the first retreat-preventing part 210 is used to abut against a second retreat-preventing part 520 arranged on a middle frame 500 to prevent the second bracket 200 from moving away from the first bracket 100 along the first direction; the deformation part 430 is configured to increase the bending and protruding degree along the air inlet direction when the distance between the first bracket 100 and the second bracket 200 is reduced.

[0056] ​By setting the first support 100 and the second support 200 corresponding to the first fixed part 410 and the second fixed part 420 respectively, and the distance between the first support 100 and the second support 200 can be reduced, so as to realize the bending and protruding degree of the deformation part 430 connected between the first fixed part 410 and the second fixed part 420 along the air inlet direction. Thus, during the injection molding process of the support, the deformation part 430 is in a state of smaller bending and protruding degree, or even in a flat state. Before injection molding, the filter screen body 400 can be laid on a relatively flat surface, and the filter screen body 400 can be more closely matched with the mold. That is, the matching of the filter screen body 400 and the mold is not affected by the bending of the filter screen body 400 in the finished state. Then, during the injection molding process, the areas of each part of the support that need to be closely combined with the filter screen body 400 can be better combined with the filter screen body 400, thereby improving the yield, and also improving the reliability of the air conditioner filter screen assembly during use, avoiding the leakage of part of the air from the filter screen body 400 and the support into the air conditioner to pollute the indoor heat exchanger. After the injection molding is completed, the first support 100 is inserted into the middle frame 500, and the second support 200 is continuously pushed to increase the bending and protruding degree of the deformation part 430, and then the first stop part 210 and the second stop part 520 on the middle frame 500 are abutted to prevent the second support 200 from moving away from the first support 100, so that the deformation part 430 can maintain the shape of protruding along the air inlet direction, and will not be opened under the restoring force of the deformation part 430.

[0057] Moreover, by setting the deformation part 430 to increase the distance between the first support 100 and the second support 200 and increase the bending and protruding direction along the air inlet direction, the filter screen assembly can present a more flat state after the injection molding is completed compared to after the filter screen assembly is installed into the middle frame 500. Thus, it is convenient to put more filter screen assemblies into the same size of packaging box or container, increase the boxing rate, and improve the efficiency of the filter screen assembly during handling, transportation and storage.

[0058] In the embodiment, the filter screen body 400 can be arranged at the lower part or the lower side of the bracket. Arranged at the lower part of the bracket means that the lower side of the filter screen body 400 also has the physical material of the bracket, because the bracket can be injected with the material forming the bracket at the lower side of the filter screen body 400 in the injection molding process. That is, the upper side and the lower side of the filter screen body 400 are both injected with the material and solidified, and the filter screen body 400 is partially cast in the material of the bracket. In the embodiment, the filter screen body 400 can be located at the middle lower part of the bracket, close to the lower surface of the bracket, that is, the first side. When the deformation part 430 is deformed, it protrudes downward, that is, protrudes in the direction of the first side. Alternatively, the filter screen body 400 can also be located at the lower side of the bracket, that is, the filter screen is attached to the lower surface of the mold before injection molding, and the filter screen is fused with the lower surface of the bracket after injection molding.

[0059] As shown in Figures 1-5 Optionally, the bracket further comprises a flexible support 300 connected between the first bracket 100 and the second bracket 200, the rigidity of the flexible support 300 in the first direction is less than that of the first bracket 100 and the second bracket 200, and the flexible support 300 is fixedly connected to the deformation part 430.

[0060] Although the rigidity of the flexible support 300 connecting the first bracket 100 and the second bracket 200 is less than that of the first bracket 100 and the second bracket 200, the rigidity of the flexible support 300 is obviously greater than that of the deformation part 430 of the filter screen body 400. After the first bracket 100 and the second bracket 200 are close to each other, the deformation part 430 is bent and protrudes in the air inlet direction, and the shape of the deformation part 430 can be maintained by the rigidity of the flexible support 300 itself, so as to ensure the overall shape of the deformation part 430 and the filtering effect.

[0061] Specifically, in the embodiment, a plurality of flexible supports 300 are arranged in the left-right direction, that is, from one end surface to the other end surface of the bracket. More specifically, four flexible supports 300 are arranged.

[0062] In the embodiment, the first bracket 100 is located at the rear part of the bracket, the flexible support 300 is located at the front part of the bracket, and the second bracket 200 is located in front of the flexible support 300. Since the indoor heat exchanger of the wall-mounted air conditioner indoor unit is generally in the shape of an inverted V or an inverted U, the embodiment is described by taking the space between the upper part of the indoor heat exchanger and the front part of the middle frame 500 or the air conditioner panel as an example.

[0063] In the embodiment, the first support 100 is composed of the second grid bars 120 extending along the left-right direction and the first grid bars 110 extending along the front-back direction. Specifically, the first support 100 includes three second grid bars 120 arranged along the front-back direction, and the number of the first grid bars 110 on the first support 100 is consistent with the number of the flexible supports 300, for example, both can be four. While the second support 200 also includes the second grid bars 120 and the first grid bars 110, the number of the second grid bars 120 arranged side by side on the second support 200 is two, and the interval between the two first grid bars 110 of the second support 200 is smaller than that of the first support 100, so that the second support 200 is significantly narrower than the first support 100 as a whole in the front-back direction.

[0064] Of course, in another implementation, the flexible supports 300 can also be arranged at the rear of the supports, although the relative positions of the first support 100 and the second support 200 do not change, the first support 100 is significantly narrower than the second support 200. Alternatively, two groups of flexible supports 300 can be arranged on one filter screen assembly along the front-back direction, one group of flexible supports 300 connects the first support 100 and the second support 200, and the other group of flexible supports 300 connects the second support 200 and a third support 510 located at the rear of the supports, i.e. the flexible supports 300 are arranged between the indoor heat exchanger and the rear of the base, and between the indoor heat exchanger and the front of the middle frame 500 or the air conditioner panel, to increase the area of the filter screen body 400 and improve the filtering effect.

[0065] The flexible support 300 can be a strip or a rib. In the embodiment, the first support 100 and the second support 200 are not absolutely inelastic, but the rigidity of the first support 100 and the second support 200 is significantly greater than that of the flexible support 300, and the deformation of the first support 100 and the second support 200 is significantly smaller than that of the flexible support 300 under stress. In the embodiment, the deformation of the flexible support 300 mainly manifests as downward deformation due to the shortening of the front-back distance of the two ends of the flexible support 300 in the plane perpendicular to the left-right direction. Specifically, the rigidity of the first grid bars 110 of the first support 100 can be improved by arranging reinforcing ribs on the first side and / or the second side of the first grid bars 110, to reduce the deformation thereof. Of course, the rigidity of the second grid bars 120 of the first support 100 and the second support 200 can also be improved by arranging reinforcing ribs on the first side and / or the second side thereof, to reduce the deformation thereof. Of course, the rigidity difference between the first support 100, the second support 200 and the flexible support 300 can also be achieved by increasing the size of the material of the first support 100 and the second support 200.

[0066] The first retreat-preventing part 210 is arranged on the second grid strip 120 of the second support 200, and the surface of the first retreat-preventing part 210 in the first direction has a first retreat-preventing surface 211, which can abut against a second retreat-preventing surface 521 arranged on the second retreat-preventing part 520 of the middle frame 500, i.e. the surface of the second retreat-preventing part 520 facing away from the first direction is the second retreat-preventing surface 521. The first retreat-preventing surface 211 and the second retreat-preventing surface 521 can be perpendicular to the first direction or be arranged at an acute angle to the first direction, and the cotangent of the acute angle is smaller than the friction coefficient between the surfaces made of the support material. When the second support 200 is directly pulled towards the front part of the middle frame 500, the first retreat-preventing surface 211 and the second retreat-preventing surface 521 can directly prevent the second support 200 from moving away from the first support 100 or generate friction self-locking to prevent the relative movement between the first retreat-preventing part 210 and the second retreat-preventing part 520. Thus, after the first retreat-preventing part 210 abuts against the second retreat-preventing part 520, only the tendency of the deformed part 430 to return to the original state or the tendency of the deformed part 430 and the flexible support strip to return to the original state can cause the first retreat-preventing part 210 and the second retreat-preventing part 520 to separate.

[0067] The first fixed part 410 is fixedly connected to the first support 100, and apparently, not all of the first fixed part 410 is fixedly connected to the first support 100. Specifically, the region of the first fixed part 410 opposite to the second grid strip 120 and the first grid strip 110 can be at least partially fixedly connected to the second grid strip 120 and the first grid strip 110, i.e. the two are fused during the injection molding of the support. Another part of the first fixed part 410 corresponds to the opening region between the second grid strip 120 and the first grid strip 110 of the first support 100, and this part is not directly fixedly connected to the first fixed part 410, so as to ensure that air can enter and be filtered from this part. The specific details of the partial fixed connection of the second fixed part 420 to the second support 200 can be referred to the specific details of the partial fixed connection of the first fixed part 410 to the first support 100 and the corresponding drawings, which will not be described here.

[0068] Furthermore, the second grid strip 120 can not only be disposed in the first bracket 100, but can also be connected to the flexible support member 300. For example, as described later, the first thinning region 310 and the second thinning region 320 can both be directly connected to the second grid strip 120. Correspondingly, the forces between each flexible support member 300 can also be transmitted through the second grid strip 120. Therefore, corresponding to some of the flexible support members 300, a first connecting part and a second connecting part are provided. Through the connection of the first connecting part and the second connecting part, after the flexible support member 300 is deformed, the forces between each flexible support member 300 can be transmitted through the second grid strip 120, causing other flexible support members 300 to deform, so as to obtain a curved bracket shape that approximates the expected shape. That is, it is not necessary to specifically provide corresponding first connecting parts and second connecting parts for all flexible support members 300 to deform the flexible support member 300.

[0069] Furthermore, in another implementation, the flexible support 300 may not be required. This is because the deformable portion 430 of the filter body 400 itself has the ability to spring back after bending. When the deformable portion 430 undergoes a downward convex bend, it spontaneously has the ability to deform into a more straight state. Therefore, after bending, the deformable portion 430 can also form a relatively smooth curved surface, and its shape is not absolutely controlled by the flexible support 300. As for how to push the first bracket 100 into the middle frame 500, since the air inlet 570 at the top of the middle frame 500 has a large area of ​​openwork, fingers can pass through these open areas to push the second grille strip 120 of the first bracket 100 towards the rear of the middle frame 500.

[0070] like Figure 5 As shown, optionally, the filter assembly is configured to be mounted on the middle frame 500, the first bracket 100 is configured to abut against the guide structure 530 of the middle frame 500 in a direction perpendicular to the first direction, and the first bracket 100 is configured to slide frictionally connect the guide structure 530.

[0071] By setting the first bracket 100 to slide and frictionally connect with the guide structure 530, resistance can be generated during the process of the first bracket 100 being pushed deeper into the middle frame 500, while continuing to push the second bracket 200. When the deformable part 430 and the flexible support 300 can no longer transmit the force of the second bracket 200, the deformable part 430 and the flexible support 300 will bend, so that the deformable part 430 and the flexible bracket will form the expected bent and protruding shape along the air intake direction during the process of installing the filter assembly into the middle frame 500, thereby improving operating efficiency.

[0072] Specifically, in this embodiment, the guide structure 530 can be a guide groove disposed on both ends of the air inlet 570. Specifically, the guide groove can be disposed on the left and right ends of the air inlet 570, extending along the front-back direction, with the opening of the guide groove facing the middle of the air inlet 570. The two side walls of the guide groove are the upper guide wall 531 and the lower guide wall 532, respectively, while the bottom wall of the guide groove is the left wall 533 and the right wall (not shown).

[0073] Of course, in another implementation, several protrusions protruding from the inner wall of the air inlet 570 can form a guide structure 530, supporting the first support 100 from both sides, such as the top and bottom sides, thereby guiding the first support 100. Alternatively, protrusions protruding towards the center area of ​​the air inlet 570 can be provided on the inner wall of the air inlet 570 to limit the left and right movement of the first support 100, or to guide the first support 100.

[0074] Figure 8 This is a top view of the support in the filter assembly provided in Embodiment 1 of the present invention; Figure 9 for Figure 8 AA section view; Figure 10 for Figure 8 AA sectional view; such as Figures 1-5 and Figures 8-10 As shown, optionally, the opposite end face of the first bracket 100 is provided with a first protrusion 130, and / or, the surface of the first bracket 100 in the second direction is provided with a first protruding ridge 140.

[0075] By providing a first protrusion 130 on the opposite end face of the first bracket 100, and / or providing a first protruding ridge 140 on the surface of the first bracket 100 in the second direction, it can abut against the guide structure 530, thereby increasing the friction between the first bracket 100 and the guide structure 530.

[0076] Specifically, in this embodiment, the second direction of the first support 100 is the upper side of the first support 100. That is, the surface of the first support 100 in the second direction is the second side surface of the first support 100. The rear end of the first protruding rib 140 is flush with the rear end of the first grid strip 110, and gradually rises along the first direction. This not only abuts against the upper guide wall 531 of the guide groove, which serves as the guide structure 530, but the gradually rising first protruding rib 140 also facilitates the guidance of the first support frame during the insertion of the first support 100 into the guide groove. Of course, in another implementation, the first protruding rib 140 can also be provided on the first side surface of the first support 100, that is, the first protruding rib 140 is provided on the lower side surface of the first grid strip 110.

[0077] Specifically, the first protruding part 130 in the embodiment can be arranged on the left side surface and the right side surface of the first support 100, i.e. the first protruding part 130 is arranged on the left side surface of the second grating strip 120 on the left side of the first support 100 and the right side surface of the second grating strip 120 on the right side of the first support 100, and the first protruding part 130 can abut against the groove bottom of the guide groove respectively to realize the left and right positioning of the first support 100 and ensure that the first support 100 has friction force when moving relative to the guide structure 530. Moreover, the guide part 150 is arranged on the left and right side end surfaces of the first support 100, i.e. the rear end of the opposite end surfaces of the first support 100, and the guide surface of the guide part 150 in the embodiment is a cylindrical surface, and the distance between the guide surfaces of the two guide parts 150 gradually increases from the rear to the front.

[0078] As shown in Figure 5 Optionally, the surface of the first retreat-preventing part 210 facing the third direction forms a first guide surface 212, and / or the surface of the second retreat-preventing part 520 facing the first direction forms a second guide surface 522, and the third direction is opposite to the first direction.

[0079] By arranging the first guide surface 212 and / or the second guide surface 522, the first retreat-preventing part 210 can be guided when the first retreat-preventing part 210 contacts the second retreat-preventing part 520 by the cooperation of the first guide surface 212 and the second guide surface. This facilitates the extrusion of the first retreat-preventing part 210 downward, so that the first retreat-preventing part 210 can pass over the second retreat-preventing part 520, facilitating the installation of the filter screen assembly.

[0080] The third direction is opposite to the first direction, i.e. when the filter screen assembly provided in the embodiment is applied to the indoor unit of the wall-mounted air conditioner, the third direction is the rear direction defined above. Moreover, the surface of the first retreat-preventing part 210 facing the third direction in the embodiment refers to the rear surface of the first retreat-preventing part 210, which is not completely and absolutely facing the rear, but can be a surface facing the rear and upward. Similarly, the surface of the second retreat-preventing part 520 facing the first direction is not completely and absolutely facing the front, but a surface facing the front and downward can also belong to the surface facing the first direction.

[0081] Specifically, in the embodiment, the first retreat-preventing part 210 is arranged on the second and third of the four first grating strips 110 arranged side by side in the second support 200, and correspondingly, the second retreat-preventing part 520 is also arranged on the second and third of the four grating strips extending in the front-rear direction of the third support 510 of the middle frame 500. The part below the corresponding second retreat-preventing part 520 of the middle frame 500 does not have a part for supporting the filter screen assembly.

[0082] The first guide surface 212 and the second guide surface 522 are arranged at an acute angle with the first direction, and the cotangent value of the acute angle is greater than the friction coefficient between the material of the bracket and the material of the middle frame 500, so that when the first guide surface 212 and the second guide surface 522 are in contact, the pressure of the second retaining portion 520 on the first retaining portion 210 can make the first retaining portion 210 move downward, so that the first retaining portion 210 can pass the second retaining portion 520 and enter the rear side of the second retaining portion 520.

[0083] Figure 6 A partial cross-sectional view of a region where the second bracket is located after the pressing portion is pressed after the filter screen assembly provided by the first embodiment of the present application is installed on the middle frame; Figure 7 A partial cross-sectional view of a region where the second bracket is located after the pressing portion is rotated after the filter screen assembly provided by the first embodiment of the present application is installed on the middle frame; as Figures 1-10 Optionally, the second bracket 200 is provided with a pressing portion 220, and the pressing portion 220 and the first retaining portion 210 are arranged along the first direction.

[0084] By arranging the pressing portion 220, when it is necessary to disassemble the filter screen assembly from the middle frame 500 for cleaning, the pressing portion 220 can be pressed to make the first retaining portion 210 and the second retaining portion 520 disengage, so as to release the locking of the second retaining portion 520 on the first retaining portion 210, thereby facilitating the disassembly of the filter screen assembly and improving the use convenience of the filter screen assembly.

[0085] As Figures 1-10 shown, in particular with reference to Figures 5-7 Optionally, the second bracket 200 includes first grid bars 110 arranged side by side, the first grid bars 110 extend along the first direction, and the pressing portion 220 protrudes from the first grid bars 110 along the second direction; and / or the pressing portion 220 is connected to adjacent first grid bars 110.

[0086] Arranging the pressing portion 220 to protrude from the first grid bars 110 along the second direction can reduce the height difference between the surface of the pressing portion 220 and the region of the third bracket 510 of the middle frame 500 where the second retaining portion 520 is arranged, so as to facilitate the user to press the pressing portion 220 by fingers when disassembling the filter screen assembly; since the second retaining portion 520 is arranged opposite to the first retaining portion 210, arranging the pressing portion 220 to be connected to adjacent first grid bars 110, the part of the pressing portion 220 connected to the first grid bars 110 is far away from the second retaining portion 520, so as to facilitate the user to press the pressing portion 220 by fingers, thereby improving the convenience during disassembly.

[0087] Specifically, in the embodiment, the pressing portion 220 not only protrudes from the first grid bars 110 in the second direction, but also connects the adjacent first grid bars 110. In other words, the pressing portion 220 can protrude from the second grid bars 120 of the second support 200, and more specifically, the second grid bars 120 where the pressing portion 220 is located can have a cross section with a wide bottom and a narrow top, while the rest of the second grid bars 120 have a uniform thickness.

[0088] As shown in Figures 1-10 , in particular with reference to Figures 5-7 , optionally, the second support 200 further has a third retreat-preventing portion 230 protruding from the second support 200 in a fourth direction, and the third retreat-preventing portion 230 is used to abut against the middle frame 500.

[0089] By providing the third retreat-preventing portion 230 protruding in the fourth direction on the second support 200 to abut against the middle frame 500, in the case that the pressing portion 220 is accidentally pressed and the retreat-preventing function of the second retreat-preventing portion 520 on the first retreat-preventing portion 210 is lost, the third retreat-preventing portion 230 can be used to abut against the middle frame 500 to prevent the second support 200 from moving away from the first support 100, thereby ensuring normal use of the filter assembly.

[0090] Specifically, in the embodiment, taking the filter assembly installed in the air inlet 570 of the wall-mounted air conditioner indoor unit as an example, the fourth direction is a substantially downward direction. The third retreat-preventing portion 230 protrudes downward and can abut against the front side wall of the air inlet 570 of the middle frame 500. In the embodiment, the third retreat-preventing portion 230 is a substantially downward protruding ridge. More specifically, the third retreat-preventing portion 230 can connect the second and third first grid bars 110 arranged side by side in the second support 200 and be in the first direction of the pressing portion 220. In another implementation, the third retreat-preventing portion 230 can also be a substantially downward protruding bump or column, but the ridge has a longer contact area with the middle frame 500 and can be supported by a larger range of the middle frame 500, so it has a better retreat-preventing effect.

[0091] When it is necessary to completely remove the filter assembly from the middle frame 500, not only is the pressing portion 220 pressed to release the locking of the first retreat-preventing portion 210 on the second retreat-preventing portion 520, but also the third retreat-preventing portion 230 needs to be lifted to release the retreat-preventing effect of the middle frame 500 on the third retreat-preventing portion 230. The specific lifting method can be that Figure 6 and Figure 7In the shown position, the pressing part 220 is pressed downward, so that the first stop part 210 is lowered to disengage from the second stop part 520, and then one of the two second grid bars 120 of the second support 200 close to the flexible support 300 or the pressing part 220 is rotated in the clockwise direction, so that the second support 200 is raised, and the third stop part 230 is raised to disengage from the middle frame 500.

[0092] It should be noted that the deformation part 430 or the deformation part 430 and the restoring action of the flexible support 300, Figure 5 In the shown position, only a horizontal left movement trend of the second support 200 is generated, which is blocked by the middle frame 500, and cannot generate a clockwise rotation movement trend of the second support 200 in the figure, so the third stop part 230 cannot disengage from the middle frame 500.

[0093] As shown in Figures 1-5 and Figure 8 、 Figure 9 As shown in the figure, optionally, the flexible support 300 has a thinning area, which includes a first thinning area 310 located in the middle of the length direction of the flexible support 300 and / or a second thinning area 320 located at the end of the length direction of the flexible support 300.

[0094] By setting the thinning area, since the rigidity of the thinning area is smaller than the rigidity of the local part of the flexible support 300 outside the thinning area, when the flexible support 300 is stressed, the deformation of the thinning area is obviously larger than that of the non-thinning area, which is beneficial to control the deformation position of the flexible support 300. By setting the first thinning area 310 in the middle of the length direction of the flexible support 300, the first thinning area 310 can be used to form a folding corner part connecting the two arms of the flexible support 300, so as to control the maximum deformation position of the flexible support 300 and reduce the deformation stress of the flexible support 300.

[0095] By setting the second thinning area 320 at the end of the length direction of the flexible support 300, the rigidity of the end of the length direction of the flexible support 300 can be reduced, which is beneficial to deform the flexible support 300 relative to the connected parts here, so as to control the deformation position of the flexible support 300, and also can reduce the deformation stress of the flexible support 300.

[0096] Among them, the first thinning area 310 on each flexible support 300 can be a plurality of spaced thinning areas, which make the first thinning area 310 of the flexible support 300 form a rack shape, and also can be a whole continuous thinning area, which also can reduce the rigidity of the local part and control the position of large deformation as the first thinning area 310.

[0097] In this embodiment, the second thinning area 320 is arranged at one end of the flexible support 300 in the length direction, i.e., the end connected with the first support 100. Similarly, the second thinning area 320 can be a continuous thinning area or a plurality of spaced thinning areas. The plurality of spaced thinning areas make the second thinning area 320 of the flexible support 300 form a rack shape, which can also reduce the local rigidity and control the position of large deformation.

[0098] As shown in FIG. 3, the first thinning area 310 can be arranged at one end of the flexible support 300 in the length direction, i.e., the end connected with the first support 100. Similarly, the first thinning area 310 can be a continuous thinning area or a plurality of spaced thinning areas. The plurality of spaced thinning areas make the first thinning area 310 of the flexible support 300 form a rack shape, which can also reduce the local rigidity and control the position of large deformation. Figure 5

[0099] When the first thinning area 310 and the adjacent area solidify, the material of the adjacent area will gradually gather and bend to the surface of the first thinning area 310 away from the first side, so that the first thinning area 310 forms a shape of a recess away from the first side, which is beneficial to intensify the protrusion of the first side when the flexible support 300 is pressed at both ends, and form the desired deformation direction.

[0100] When the first thinning area 310 bends, the surface away from the first side is in a recessed state and is pressed more. Thinning the surface of the first thinning area 310 can reduce the material of the surface of the first thinning area 310, so as to reduce the degree of pressure of the material and reduce the possibility of cracking caused by excessive pressure of the material.

[0101] When the second thinning area 320 and the adjacent area solidify, the material of the adjacent area will gradually gather and bend to the surface of the second thinning area 320 away from the first side, so that the second thinning area 320 forms a shape of a recess away from the second side, which is beneficial to deform the area of the flexible support 300 adjacent to the second thinning area 320 in the direction that the first thinning area 310 protrudes to the first side when the flexible support 300 is pressed at both ends, and form the desired deformation direction.

[0102] When the first side of the second thinning area 320 bends, the first side is in a recessed state and is pressed more. Thinning the surface of the second thinning area 320 can reduce the material of the surface of the second thinning area 320, so as to reduce the degree of pressure of the material and reduce the possibility of cracking caused by excessive pressure of the material.

[0103] ​In the embodiment, the first thinning area 310 and the first side thinning recess of the second thinning area 320 are combined. In other implementations, the first thinning area 310 and the first side thinning recess of the second thinning area 320, or the first side thinning recess of the first thinning area 310 and the second side thinning recess of the second thinning area 320, or the second side thinning recess of the first thinning area 310 and the first side thinning recess of the second thinning area 320 can be combined. All of them can play a corresponding effect.

[0104] Embodiment two:

[0105] Figure 11 A partial view of a middle frame in an air conditioner according to the second embodiment of the present application is shown in the figure; Figure 12 A partial view of a middle frame in an air conditioner according to the second embodiment of the present application is shown in the figure; Figure 4 、 Figure 5 and Figure 11 、 Figure 12 As shown in the figures, the second embodiment also provides an air conditioner, which comprises the middle frame 500 and the filter screen assembly of any one of the above, the middle frame 500 is provided with an air inlet 570, the filter screen assembly is installed in the air inlet 570, the air inlet 570 is provided with a third support 510, and the third support 510 is provided with a second stop portion 520.

[0106] By setting the filter screen assembly in the air conditioner, the air conditioner has all the advantages of the filter screen assembly, which will not be repeated here.

[0107] Specifically, in the embodiment, the third support 510 of the middle frame 500 can also be formed by longitudinal and transverse intersecting grid bars, specifically, including a third grid bar 511 extending in the front-rear direction and a fourth grid bar 512 extending in the left-right direction. The first grid bar 110 of the first support 100 can be arranged corresponding to the third grid bar 511. The second grid bar 120 can correspond to the fourth grid bar 512, except that one fourth grid bar 512 of the first support 100 is farthest away from the flexible support 300, because this grid bar can correspond to the crossbeam at the rear of the top of the middle frame 500. With this arrangement, it is beneficial to reduce the hindering effect of the third support 510 on the airflow alone to improve the air intake efficiency.

[0108] In the embodiment, the third grid bar 511 and the fourth grid bar 512 at the edge of the third support 510 generally present a Chinese character "concave" shape, and the second stop portion 520 is arranged at the corner of the top of the two side walls of the concave part of the concave shape based on the writing direction of the Chinese character, and the first stop portion 210 is arranged corresponding to the second stop portion 520.

[0109] In addition to corresponding to the second grid bars 120 of the first support 100, the third support 510 also has a fourth grid bar 512 corresponding to the second grid bars 120 connecting the lowest parts of the flexible support 300. The fourth grid bar 512 is arranged to reduce the length of the third support 510 belonging to the cantilever beam structure part, and improve the rigidity of the connection between the second stop part 520 and the third stop part 230.

[0110] In addition, in the embodiment, the middle frame 500 can also be provided with a first support part 550 and a second support part 560, the first support part 550, the second support part 560 and the guide lower wall 532 of the guide groove are arranged in sequence along the reverse direction of the first direction, and the third support 510 on the middle frame 500 can be matched with the three to support the filter screen assembly inserted into the middle frame 500 in the up-down direction. The first support part 550 and the second support part 560 are arranged at intervals, and the interval between the two can be used for the deformation part 430 or the deformation part 430 and the flexible support 300 to bend downward.

[0111] The first support part 550 can be used to prevent the deformation part 430 or the deformation part 430 and the flexible support from bending downward too early, so as to realize the transmission of the force input into the first support 100 by the flexible support 300. That is, during the insertion of the filter screen assembly into the middle frame 500, the deformation part 430 can only begin to deform downward after passing the part of the first support part 550. In other words, the first support part 550 can limit the position of the deformation part 430 in the front-rear direction to deform on the side close to the second support 200, and the second support part 560 arranged at the position close to the guide lower wall 532 of the guide groove can limit the position of the deformation part 430 in the front-rear direction to deform on the side close to the first support 100. Therefore, after the filter screen assembly is installed in place, the first support part 550 and the second support part 560 can limit the deformation range of the filter screen body 400 to the expected position, so as to ensure that the deformation part 430 bent in the air inlet direction does not significantly interfere with the air inlet process.

[0112] In addition, the front side wall of the air inlet 570 of the middle frame 500 is also provided with a groove 540 recessed forward from the side wall to match the third stop part 230, so as to facilitate the positioning of the third stop part 230.

[0113] The action principle of the embodiment is as follows:

[0114] Figure 13 A partial schematic view of the air conditioner in which the filter screen assembly is just inserted into the middle frame is provided for the second embodiment of the application; Figure 14 A partial sectional view of the air conditioner in which the filter screen assembly is just inserted into the middle frame is provided for the second embodiment of the application; Figure 15Figure 2 is a partial view of the air conditioner of the second embodiment of the present application, showing the first bracket being inserted into the guide structure; Figure 16 Figure 3 is a partial cross-sectional view of the air conditioner of the second embodiment of the present application, showing the first bracket being inserted into the guide structure; Figures 4-5 and Figures 13-16 The process of the filter screen assembly being loaded into the middle frame 500 is shown.

[0115] As Figure 13 and Figure 14 The state of the first bracket 100 just being inserted into the middle frame 500 is shown. Under the guidance of the guide portion 150, the first bracket 100 can smoothly enter between the two side walls of the air inlet 570 in the left-right direction, and under the action of the first protruding rib 140, the first bracket 100 can also smoothly enter between the third bracket 510 and the first support portion 550.

[0116] Figure 14 In the figure, although the second retreat-stop portion 520 is located above the rear end portion of the first bracket 100, and the first support portion 550 is located below the rear end portion of the first bracket 100. However, Figure 14 As can be seen in the figure, the second retreat-stop portion 520 is represented by a cross-sectional line, and the first support portion 550 is not represented by a cross-sectional line. It is explained that the cross-section passes through the second retreat-stop portion 520, but does not pass through the first support portion 550. That is, in the left-right direction, the first support portion 550 does not correspond to the second retreat-stop portion 520, and even if the first bracket 100 is pressed down by the second retreat-stop portion 520, since the first bracket 100 is not an absolutely rigid body, after the middle portion of the first bracket 100 is pressed down by the second retreat-stop portion 520, the left and right ends of the first bracket 100 can still be supported by the first support portion 550. Therefore, the arrangement of the first support portion 550 and the second retreat-stop portion 520 will not cause the first bracket 100 to be unable to enter the middle frame 500.

[0117] Figure 15 and Figure 16 The state of the first bracket 100 being inserted into the guide groove as the guide structure 530 is shown. In the figure, it has been shown that the first protruding rib 140 abuts against the guide upper wall 531 of the guide groove, the first bracket 100 moves relative to the middle frame 500, and a frictional force is generated therebetween. Similarly, the first protruding portion 130 on the first bracket 100 also moves relative to the groove bottom of the guide groove, and a frictional force is generated therebetween. Thus, it is ensured that the movement of the first bracket 100 can be resisted by the middle frame 500. At this time, since the bottom surface of the flexible support member 300 is supported by the first support portion 550, the flexible support member 300 can also transmit the backward thrust of the second bracket 200. Of course, the thrust on the first bracket 100 can also be applied to the second grid strip 120 of the first bracket 100 by the operator through the hollowed-out area between the third brackets.

[0118] Figure 4 and Figure 5 The figure shows the state after the first bracket 100 has been installed in place. As the first bracket 100 encounters resistance during backward movement, and there is no first support portion 550 to support below the flexible support member 300 and the deformation portion 430, the flexible support member 300 and the deformation portion 430 deform downward. Moreover, the second support portion 560 confines the deformation of the deformation portion 430 and the flexible support member 300 within the left region shown in Figure 5 When the first guiding surface 212 meets the second guiding surface 522, under the thrust force received by the second bracket 200, the first anti-retreat portion 210 moves downward and then crosses over the second anti-retreat portion 520. Then, under the restoring force of the flexible support member 300 and the deformation portion 430, the first anti-retreat portion 210 abuts against the second anti-retreat portion 520 to prevent the flexible support member 300 from further unfolding, that is, to prevent the second bracket 200 from moving away from the first bracket 100. At this time, the third anti-retreat portion 230 also abuts against the groove 540 of the middle frame 500, achieving a double insurance for anti-retreat.

[0119] As Figure 6 shown, when it is necessary to remove the filter component, the pressing portion 220 can be pressed downward, thereby, the second anti-retreat portion 520 also moves downward accordingly, which can be seen from the comparison with the partial enlarged view in Figure 6 and Figure 5 . Moreover, since the pressing portion 220 is connected to two first grid bars 110, and the third bracket 510 also presents the shape of a Chinese character 'concave', the operator can directly press the pressing portion 220 downward without obstruction to make the second anti-retreat portion 520 descend and release the locking between the first anti-retreat portion 210 and the second anti-retreat portion 520.

[0120] As Figure 7 shown, the operator can continue to rotate the pressing portion 220 to lift the third anti-retreat portion 230, which can be seen from the comparison with Figure 7 and Figure 6 . The third anti-retreat portion 230 is no longer blocked by the middle frame 500, and along the upper left direction shown in Figure 7 , the second bracket 200 can be pulled out from the middle frame 500, and then the degree of convex deformation of the flexible support member 300 and the deformation portion 430 is weakened, and finally the first bracket 100 can also be pulled out from the guiding structure 530 and the middle frame 500. It should be noted that although the first support portion 550 supports the second bracket 200 at the opposite ends of the second bracket 200, since the second bracket 200 itself is not an absolute rigid body, when the pressing portion 220 in the middle of the second bracket 200 is pressed downward or rotated, it can correspondingly drive the first anti-retreat portion 210 to descend and the third anti-retreat portion 230 to rise, and will not be significantly restricted by the first support portion 550.
