Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a filter screen limiting device and an air conditioner. Background Art

[0002] Currently, the filter screen installed on the air conditioner is mainly held on the rear enclosure of the air conditioner by the filter screen itself. However, the existing filter screen installation structure lacks an effective limiting device for the filter screen, and it is easy for the filter screen to loosen or even fall off during assembly and use. Summary of the Invention

[0003] The problem solved by the present invention is how to effectively limit the filter screen to prevent the filter screen from loosening or falling off.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] In one aspect, the present invention provides a filter screen limiting device, including a filter screen mounting plate and a filter screen limiting block provided on the filter screen mounting plate. A chute for accommodating the filter screen is formed on the filter screen mounting plate, and the filter screen limiting block is connected to the wall of the chute and is used to abut against the filter screen to prevent the filter screen from disengaging from the chute.

[0006] The filter screen limiting device provided by the present invention, by providing a filter screen limiting block on the filter screen mounting plate and connecting the filter screen limiting block to the wall of the chute, when assembling the filter screen, the filter screen limiting block can abut against the filter screen, thereby preventing the filter screen from disengaging from the chute. Compared with the prior art, the filter screen limiting device provided by the present invention can limit the filter screen through the filter screen limiting block, prevent the filter screen from disengaging from the chute, and ensure the installation effect of the filter screen.

[0007] Further, side convex strips are provided on the filter screen mounting plate, and chutes are provided on one side or both sides of the side convex strips. The side convex strips form the wall of the chute, and the filter screen limiting block is provided on the side convex strips and is used to abut against the filter screen on one side or both sides.

[0008] The filter screen limiting device provided by the present invention can have chutes provided on both sides of the side convex strips, so that the filter screens in the two chutes can be abutted and limited. When assembling, two filter screens can be fixed simultaneously, and the limiting range is wide.

[0009] Further, the filter screen limiting block includes a connecting portion and a limiting portion. The connecting portion is provided on the side convex strip, the limiting portion is connected to the connecting portion and is horizontally disposed on the chute, and a clamping gap for clamping the filter screen is formed between the bottom wall of the chute and the limiting portion. The limiting portion is used to abut against the filter screen to prevent the filter screen from disengaging from the chute.

[0010] The filter screen limiting device provided by the present invention has a connecting part arranged on the side convex strip, and the limiting part is horizontally placed on the sliding groove. The limiting part is used to limit the filter screen, and the filter screen is clamped by the clamping gap formed between the limiting part and the bottom wall of the sliding groove, further ensuring the fixing effect of the filter screen and preventing the filter screen from slipping out of the sliding groove.

[0011] Further, the limiting part is inclined with respect to the bottom wall of the sliding groove.

[0012] In the filter screen limiting device provided by the present invention, the limiting part is inclined with respect to the bottom wall of the sliding groove, so that the limiting part is thickened in the radial force direction, which can effectively increase the thickness of its stress surface, thereby enhancing the structural strength of the limiting part, preventing the force exerted on the limiting part by the filter screen during assembly or disassembly from being too large and causing deformation or fracture of the limiting part, and improving the service life of the limiting part.

[0013] Further, the limiting part is provided with a guiding inclined surface, and the guiding inclined surface corresponds to the bottom wall of the sliding groove, so that the distance between the end of the limiting part close to the connecting part and the bottom wall of the sliding groove is smaller than the distance between the end of the limiting part far from the connecting part and the bottom wall of the sliding groove.

[0014] In the filter screen limiting device provided by the present invention, during the installation process, the filter screen can slide into the clamping gap along the guiding inclined surface and is finally fixed in the sliding groove. By setting the guiding inclined surface, it can play a guiding role during the installation process of the filter screen, facilitating installation and improving work efficiency.

[0015] Further, the included angle between the guiding inclined surface and the corresponding bottom wall of the sliding groove is 45° - 50°.

[0016] In the filter screen limiting device provided by the present invention, the guiding inclined surface is set to be inclined at 45° to 50°, which can further play a guiding role during the installation process of the filter screen, making the installation more convenient and further improving work efficiency.

[0017] Further, guiding convex strips are also provided on the filter screen mounting plate, and the guiding convex strips are arranged opposite to the side convex strips.

[0018] In the filter screen limiting device provided by the present invention, by setting the guiding convex strips and arranging the guiding convex strips opposite to the side convex strips, it can first conduct dispersion guiding through the guiding convex strips when installing the filter screen, facilitating installation and improving assembly efficiency.

[0019] Further, a plurality of parallel sliding grooves are formed on the filter screen mounting plate. One end of each sliding groove has an opening for loading the filter screen, and filter screen limiting blocks are arranged on the groove walls of each sliding groove, and the distances between adjacent two filter screen limiting blocks and the corresponding opening are different.

[0020] The filter limiting device provided by the present invention limits the filter screens in multiple slide grooves by means of multiple limiting blocks, and the distances between two adjacent filter limiting blocks and the corresponding openings are different, so that the filter screens can be limited and assembled in stages between two adjacent filter limiting blocks, which is beneficial to improving assembly efficiency.

[0021] Furthermore, the distance between one of the two adjacent filter limit blocks and the corresponding opening is 2 / 3 of the length of the slide groove, and the distance between the other one and the corresponding opening is 3 / 4 of the length of the slide groove.

[0022] The filter limiting device provided by the present invention can limit the filter at 2 / 3 and 3 / 4 respectively by arranging filter limiting blocks at 2 / 3 and 3 / 4 of the two slide grooves respectively, thereby achieving the effect of staggered limiting and ensuring the limiting effect. At the same time, the filters can be installed in sequence during assembly, which also improves the assembly efficiency.

[0023] On the other hand, the present invention provides an air conditioner, including a filter limiting device, the filter limiting device including a filter mounting plate and a filter limiting block arranged on the filter mounting plate, the filter mounting plate is provided with a slide groove for accommodating the filter, the filter limiting block is connected to the groove wall of the slide groove, and is used to support the filter to prevent the filter from detaching from the slide groove.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] First embodiment

[0036] See also Figures 1 to 3 The present embodiment provides a filter limiting device 100, which can limit the filter 200 to prevent the filter 200 from falling off or loosening.

[0037] The filter limiting device 100 provided in this embodiment includes a filter mounting plate 110 and a filter limiting block 130 disposed on the filter mounting plate 110. The filter mounting plate 110 is provided with a chute 111 for accommodating a filter 200. The filter limiting block 130 is connected to the chute wall of the chute 111 and is used to abut against the filter 200 to prevent the filter 200 from being separated from the chute 111. By arranging the filter limiting block 130 on the filter mounting plate 110 and the filter limiting block 130 being connected to the chute wall of the chute 111, when the filter 200 is assembled, the filter limiting block 130 can abut against the filter 200, thereby preventing the filter 200 from being separated from the chute 111. Compared with the prior art, the filter limiting device 100 provided by the present invention limits the filter 200 by means of the filter limiting block 130 , thereby preventing the filter 200 from being separated from the slide groove 111 , and ensuring the installation effect of the filter 200 .

[0038] In this embodiment, the filter installation plate 110 is the rear panel of the air conditioner, and the rear panel and the filter 200 are both arc-shaped, and a chute 111 for accommodating the filter 200 is provided on the rear panel. Specifically, a convex strip extending into the chute 111 is provided on one side surface of the filter 200, and during assembly, the convex strip slides and is accommodated in the chute 111, and the filter stopper 130 abuts against the other side surface of the filter 200, so that the filter 200 can be fixed in the chute 111, preventing the filter 200 from falling off from the chute 111. Of course, in this embodiment, the rear panel and the filter 200 can also be planar, and the filter stopper 130 can also be provided to limit the filter.

[0039] It should be noted that in this embodiment, a grille structure is provided on the rear bulkhead. Specifically, the grille structure includes a plurality of grille frame bars 113. The grille frame bars 113 are hollow and correspond to the filter net 200 for admitting air. The chute 111 is provided between two adjacent grille frame bars 113.

[0040] In this embodiment, side convex strips 115 are provided on the filter net mounting plate 110. The chute 111 is provided on one side or both sides of the side convex strips 115, and the side convex strips 115 form the chute wall of the chute 111. The filter net limiting block 130 is provided on the side convex strips 115 for abutting against one side or both sides of the filter net 200. Specifically, in this embodiment, the side convex strips 115 are provided between two adjacent grille frame bars 113, so that the channel between the two adjacent grille frame bars 113 is divided into two chutes 111. The filter net limiting block 130 is provided on the side convex strips 115 and extends to both sides, so as to be able to abut and limit the filter net 200 in the two chutes 111, and two filter nets 200 can be fixed simultaneously during assembly, and the limiting range is wide.

[0041] See Figure 4 , in this embodiment, a guiding convex strip 117 is further provided on the filter net mounting plate 110. The guiding convex strip 117 is arranged opposite to the side convex strip 115. By providing the guiding convex strip 117 and arranging the guiding convex strip 117 opposite to the side convex strip 115, it is possible to first perform dispersion guiding through the guiding convex strip 117 when installing the filter net 200, which is convenient for installation and improves the assembly efficiency.

[0042] It should be noted that the guiding convex strip 117 and the side convex strip 115 are arranged along the same circumference, and there is a certain interval between the guiding convex strip 117 and the side convex strip 115. In other preferred embodiments, the guiding convex strip 117 continues to extend along the circumferential direction of the circle coaxial with the side convex strip 115 to the side convex strip 115 and is integrally provided with the side convex strip 115, and it can also achieve the functions of guiding and dispersing the filter net 200.

[0043] Combined with see Figures 5 to 7The filter screen limiting block 130 includes a connecting portion 131 and a limiting portion 133. The connecting portion 131 is arranged on the side convex strip 115. The limiting portion 133 is connected to the connecting portion 131 and is horizontally arranged on the chute 111. A clamping gap for clamping the filter screen 200 is formed between the bottom wall of the chute 111 and the limiting portion 133. The limiting portion 133 is used to abut against the filter screen 200 to prevent the filter screen 200 from escaping from the chute 111. The connecting portion 131 is arranged on the side convex strip 115, the limiting portion 133 is horizontally arranged on the chute 111, and the limiting portion 133 is used to limit the filter screen 200. The filter screen 200 is clamped by the clamping gap formed between the limiting portion 133 and the bottom wall of the chute 111, which further ensures the fixing effect of the filter screen 200 and prevents the filter screen 200 from escaping from the chute 111.

[0044] It should be noted that the limiting portion 133 is horizontally placed on the slide groove 111, which means that the limiting portion 133 extends in a direction perpendicular to the direction of the slide groove 111, and the orthographic projection of the limiting portion 133 in a direction perpendicular to the bottom wall can fall on the bottom wall of the slide groove 111, so that the limiting portion 133 spans the slide groove 111 to achieve the limitation of the filter 200.

[0045] It should also be noted that in this embodiment, the connection portion 131, the limiting portion 133 and the side convex strip 115 are integrally arranged, and the limiting portion 133 is in a rectangular block shape and is arranged above the slide slot 111, so as to limit the filter screen 200 in the slide slot 111. In this embodiment, the connection portion 131, the limiting portion 133 and the side convex strip 115 are all made of ABS (Acrylonitrile Butadiene Styrene plastic) plastic, that is, made of acrylonitrile-butadiene-styrene plastic, which has good strength and is used to limit the displacement of the filter screen 200, and the rear panel is also made of ABS plastic, and the side convex strip 115 is integrally arranged on the rear panel. Of course, the material here is only an example, and is not limited to ABS plastic, and can also be other materials such as PP (Polypropylene, polypropylene).

[0046] In this embodiment, the connecting portion 131 and the limiting portion 133 form a T-shaped structure, so that the limiting portion 133 extends from the connecting portion 131 to both sides and is horizontally placed on the slide grooves 111 on both sides of the side protrusion 115. The limiting portion 133 spans the slide grooves 111 on both sides of the side protrusion 115, thereby limiting the two filter screens 200 at the same time.

[0047] In this embodiment, the limiting portion 133 is inclined relative to the bottom wall of the slide groove 111, so that the limiting portion 133 is thickened in the radial force direction, which can effectively enhance the thickness of its force-bearing surface. Specifically, the limiting portion 133 is upwardly tilted relative to the filter mounting plate 110, thereby enhancing the structural strength of the limiting portion 133, avoiding excessive force exerted on the limiting portion 133 by the filter 200 during assembly or disassembly, causing deformation or breakage of the limiting portion 133, and improving the service life of the limiting portion 133.

[0048] It should be noted that the limiting portion 133 is in the shape of a rectangular block, and the limiting portion 133 is obliquely arranged above the slide groove 111, so that during assembly or after assembly, the filter 200 will apply upward stress to the bottom edge of the limiting portion 133. Due to the inclined setting of the limiting portion 133, the overall thickness of the upper limit portion 133 in the force direction is increased, and the distance between the force point and the connecting portion 131 is also reduced, thereby reducing the stress received by the connecting portion 131 and enhancing the structural strength of the limiting portion 133.

[0049] In this embodiment, the limiting portion 133 is provided with a guiding inclined surface 135, and the guiding inclined surface 135 corresponds to the bottom wall of the slide groove 111, so that the distance between the end of the limiting portion 133 close to the connecting portion 131 and the bottom wall of the slide groove 111 is smaller than the distance between the end of the limiting portion 133 away from the connecting portion 131 and the bottom wall of the slide groove 111. During the installation process, the filter screen 200 can slide into the clamping gap along the guiding inclined surface 135 and finally be fixed in the slide groove 111. By providing the guiding inclined surface 135, it can play a guiding role during the installation process of the filter screen 200, facilitate installation, and improve work efficiency.

[0050] It should be noted that, in this embodiment, the guide bevel 135 is a side surface of the limiting portion 133 close to the bottom wall of the slide groove 111, and is a side surface away from the side ridge 115. The guide bevel 135 is inclined upward so that an expanded opening is formed between the slide groove 111 and the guide bevel 135. The bottom of the expanded opening is the clamping gap formed between the limiting portion 133 and the bottom wall of the slide groove 111. During assembly, the filter screen 200 can be inserted into the clamping gap from the guide bevel 135 on the upturned limiting portion 133 and firmly fixed in the slide groove 111, thereby improving the assembly accuracy and efficiency.

[0051] In this embodiment, the included angle between the guiding inclined surface 135 and the bottom wall of the corresponding sliding groove 111 is 45° - 50°. Specifically, the included angle between the guiding inclined surface 135 and the bottom wall of the corresponding sliding groove 111 is 48°. Since the filter screen mounting plate 110 is arc-shaped, the bottom wall of the sliding groove 111 is also arc-shaped. The direction of the guiding inclined surface 135 and the corresponding bottom wall refers to the tangent direction at this bottom wall. Setting the guiding inclined surface 135 to be inclined at 45° to 50° can further play a guiding role during the installation of the filter net 200, making the installation more convenient and further improving the work efficiency.

[0052] It should be noted that the guiding inclined surface 135 extends to the connecting portion 131, making the connecting portion 131 flush with the limiting portion 133. In other preferred embodiments of the present invention, the connecting portion 131 can also be vertically arranged on the side rib 115, and the limiting portion 133 is arranged at the top of the connecting portion 131. The limiting portion 133 itself can also achieve the dual functions of limiting and guiding.

[0053] See Figure 8 , a plurality of parallel sliding grooves 111 are formed on the filter screen mounting plate 110. One end of each sliding groove 111 has an opening for loading the filter net 200, and filter screen limiting blocks 130 are arranged on the groove walls of each sliding groove 111, and the distances between adjacent two filter screen limiting blocks 130 and the corresponding openings are different. The filter net 200 in a plurality of sliding grooves 111 is limited by a plurality of limiting blocks, and the distances between adjacent two filter screen limiting blocks 130 and the corresponding openings are different, so that hierarchical limiting and hierarchical assembly of the filter net 200 can be realized between adjacent two filter screen limiting blocks 130, which is beneficial to improving the assembly efficiency.

[0054] In this embodiment, the distance between one of the adjacent two filter screen limiting blocks 130 and the corresponding opening is 2 / 3 of the length of the sliding groove 111, and the distance between the other and the corresponding opening is 3 / 4 of the length of the sliding groove 111. By respectively arranging the filter screen limiting blocks 130 at the 2 / 3 position and 3 / 4 position of two sliding grooves 111, the filter net 200 can be limited at the 2 / 3 position and 3 / 4 position respectively, so as to achieve the effect of staggered limiting, ensure the limiting effect, and at the same time, when assembling, loading in sequence also improves the assembly efficiency. In addition, the filter screen limiting blocks 130 arranged at different positions can also play a role of hierarchical guiding, further improving the assembly efficiency. Of course, the setting position of the filter screen limiting block 130 here can also be other positions such as 4 / 5 or 1 / 2, as long as the adjacent two filter screen limiting blocks 130 can be staggered and hierarchically guided.

[0055] In this embodiment, three filter screen limit blocks 130 are provided on the rear bulkhead. Each filter screen limit block 130 is used to limit two sliding grooves 111 between two grille frame bars 113, thereby limiting two filter screen sheets 200.

[0056] In summary, a filter screen limiting device 100 provided in this embodiment limits the filter screen 200 placed in the sliding groove 111 by arranging a filter screen limit block 130 on the groove wall of the sliding groove 111 and horizontally placing the limiting portion 133 of the filter screen limit block 130 on the sliding groove 111, so as to prevent the filter screen 200 from coming out of the sliding groove 111. In addition, the limiting portion 133 is inclined with respect to the bottom wall of the sliding groove 111, which can effectively increase the structural strength of the filter screen limit block 130, and the limiting portion 133 is provided with a guiding inclined surface 135, which plays a guiding role. When assembling, the filter screen 200 is loaded into the sliding groove 111 through the guiding inclined surface 135, improving the assembly efficiency. And the adjacent two filter screens are limited in a hierarchical guiding manner, and are respectively arranged at the 2 / 3 position and the 3 / 4 position of the sliding groove 111, thereby further improving the assembly efficiency.
