[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0049] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0050] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0051] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0052] See also Figure 1-11 As shown, according to an embodiment of the utility model, a filter assembly is provided, which includes a panel 1 and a mesh frame 3 for supporting the filter. The mesh frame 3 has a first end 31 and a second end 32 opposite to each other. The panel 1 is located at the first end 31 of the mesh frame 3, and the panel 1 is detachably connected to the mesh frame 3. The filter can be integrally formed on the mesh frame 3.

[0053] In the above example, since the panel 1 and the grid 3 are detachably connected, the panel 1 and the grid 3 can be processed separately. Compared with the prior art in which the panel 1 and the grid 3 are integrally formed, the present invention separates the panel 1 from the grid 3 so that the panel 1 can be processed separately, thereby reducing the processing difficulty. This can effectively reduce the situation where the panel 1 is scrapped due to appearance defects, ensure the appearance quality of the panel 1, and improve the qualified rate of the panel 1 product. In addition, since the scrap amount of the panel 1 is reduced, unnecessary waste is avoided, the production efficiency is improved, and the production cost is reduced.

[0054] In addition, since the panel 1 can be processed separately, the performance of secondary processing such as spraying and electroplating of the panel 1 can be met.

[0055] In some embodiments, Figure 1 As shown, the panel 1 may be provided with a handle 2, which provides a handhold and a force application point for the filter assembly and the external air outlet track 7, so as to facilitate the user to push the grid 3 into or out of the external air outlet track 7. The panel 1 is also used to be assembled on the body of a household appliance such as an air conditioner to provide support for the grid 3. When the filter assembly is assembled on the household appliance, the grid 3 drives the filter to be inserted into the air outlet track 7, the panel 1 is stuck on the body of the household appliance, and the panel 1 is exposed outside the household appliance.

[0056] The handle portion 2 is generally arranged on the front side of the panel 1, that is, the side exposed to the outside of the body of the household appliance.

[0057] In the prior art, the grid 3 and the panel 1 are made of the same material, which results in the grid 3 being harder, difficult to deform, and difficult to disassemble. In the above example, since the panel 1 and the grid 3 can be processed separately, the panel 1 and the grid 3 can be made of different materials. For example, the panel 1 can be made of harder ABS or HIPS materials to ensure that the secondary processing performance requirements such as spraying and electroplating are met. The grid 3 can be made of softer materials such as PP to increase the softness of the grid 3, making it easier to disassemble the filter assembly from the external air outlet track 7, solving the problem of the filter assembly being difficult to disassemble from the external air outlet track 7.

[0058] In order to realize the function of detachably connecting the aforementioned grid 3 and the panel 1, in some embodiments, the aforementioned panel 1 and the grid 3 can be detachably connected by a snap-on manner.

[0059] In some embodiments, Figures 3 to 7As shown, one of the aforementioned panel 1 and the grid 3 is provided with a buckle 12, and the other is provided with a slot 13 for engaging with the buckle 12. Among them, the one of the panel 1 and the grid 3 on which the slot 13 is provided is taken as the first component, and the other is taken as the second component. The first component has a first side 307 and a second side 308 opposite to each other. The first component also has a first through hole 301 that passes through the first side 307 and the second side 308. The aforementioned slot 13 is provided on the second side 308 of the first component. The buckle 12 is used to pass through the first through hole 301 along the first A direction a from the first side 307, and then snap into the slot 13 along the second direction b. The second direction b is perpendicular to the first A direction a.

[0060] In the above example, the buckle 12 must first pass through the first through hole 301 before it can be engaged with the slot 13, and the direction in which the buckle 12 passes through the first through hole 301 is perpendicular to the direction in which the buckle 12 is inserted into the slot 13 for engagement. In this way, after the buckle 12 is engaged with the slot 13, it can prevent the buckle 12 from loosening from the first through hole 301, which is beneficial to improving the connection stability between the panel 1 and the frame 3.

[0061] in, Figure 7 A structural example is shown in which a buckle 12 is arranged on a panel 1 and a slot 13 is arranged on a grid 3. In this case, the panel 1 is the second component in the above example, the grid 3 is the first component in the above example, and the aforementioned first via 301 is arranged on the grid 3.

[0062] In some embodiments, the buckle 12 may be L-shaped, and the buckle 12 has a first connecting arm and a second connecting arm connected to each other, an end of the first connecting arm facing away from the second connecting arm is connected to the second component, and an end of the second connecting arm facing away from the first connecting arm has a hook portion. The buckle 12 hooks the groove wall of the slot 13 through the hook portion to achieve the snap connection with the slot 13.

[0063] It should be noted here that the number of the buckles 12 can be more than two, and the number of the slots 13 is equal to the number of the buckles 12 and corresponds one to one.

[0064] In some embodiments, Figure 2 As shown, the aforementioned second direction b is perpendicular to the direction d in which the grid is inserted into the external air outlet track, so that the grid 3 can be prevented from being disengaged during the plugging and disassembly process with the external air outlet track 7, causing the grid 3 to be retained in the external air outlet track 7, which not only ensures the convenience and high efficiency of disassembly and assembly of the grid 3 and the external air outlet track 7, but also ensures the fixing stability between the panel 1 and the grid 3. In a specific application example, the direction d in which the grid is inserted into the external air outlet track can be the length direction of the grid 3, and correspondingly, the aforementioned second direction b is the width direction of the grid 3. The external air outlet track 7 is generally an air inlet.

[0065] In some embodiments, Figure 7 As shown, the second side 308 may be provided with a first guiding slope 303 , and the first guiding slope 303 is used to guide the movement of the buckle 12 into the slot 13 along the second direction b, so as to improve the accuracy of the buckle 12 being inserted into the slot 13 .

[0066] In some embodiments, the aforementioned filter assembly may also include a first limiting structure, which is used to keep the panel 1 and the frame 3 relatively fixed in the first A direction a and the opposite direction of the first A direction a, so as to improve the connection stability between the panel 1 and the frame 3.

[0067] In order to realize the function of the first limiting structure, in some embodiments, Figure 7 As shown, the aforementioned first limiting structure may include a latch 11 and a first limiting block 4. One of the latch 11 and the first limiting block 4 is arranged on the panel 1, and the other is arranged on the grid 3. Among them, one of the panel 1 and the grid 3 on which the first limiting block 4 is arranged is taken as the third component, and the other is taken as the fourth component. The third component has a through second through hole 302 in the first A direction a. The aforementioned latch 11 is used to pass through the second through hole 302 along the first B direction, and then when the buckle 12 moves along the second direction b to engage with the card slot 13, the latch 11 abuts against the first limiting block 4 along the first C direction, so as to fix the third component on the fourth component along the first C direction through the first limiting block 4. The first C direction is opposite to the first B direction. Among them, when the third component and the first component are the same component, the first A direction a is the same direction as the first B direction; when the third component and the second component are the same component, the first A direction a is opposite to the first B direction.

[0068] The above-mentioned latch pin 11 needs to pass through the second through hole 302 before it can abut against the first limiting block 4 .

[0069] For ease of understanding, the following example is given by taking the third component and the aforementioned first component as the same component and both being the grid 3, and the second component and the fourth component as the same component and both being the panel 1. Figure 7 As shown, in a specific application example, the buckle 12 is arranged on the panel 1, the slot 13 is arranged on the grid 3, the first limit block 4 is arranged on the grid 3, the latch 11 is arranged on the panel 1, and the first A direction and the first B direction are the same direction, and both are Figure 7 The latch 11 first passes through the second through hole 302 along direction a, and then when the panel 1 drives the buckle 12 to move to the right position along the second direction b, the latch 11 abuts against the first limit block 4 along the first direction C, which is opposite to direction a. The first direction C is Figure 7 At this time, the latch 11 fixes the grid 3 on the panel 1 along the direction b through the first limit block 4.

[0070] In the above example, the latch 11 cooperates with the first limit block 4 to keep the panel 1 and the grid 3 relatively fixed in both the a direction and the b direction, so as to improve the connection stability between the panel 1 and the grid 3 .

[0071] In some embodiments, Figure 7 As shown, the aforementioned latch 11 may be L-shaped, and the latch 11 has a third connecting arm and a fourth connecting arm connected to each other, and an end of the third connecting arm facing away from the fourth connecting arm is connected to the fourth component. Figure 7 A schematic diagram showing a case where the fourth component is a panel 1 and an end of the third connecting arm facing away from the fourth connecting arm is connected to the panel 1 .

[0072] It should be noted here that the number of the above-mentioned latches 11 can be more than two, and the number of the first limit blocks 4 is equal to the number of the latches 11 and corresponds one to one.

[0073] like Figure 7 As shown, the first limiting block 4 may be provided with a third guiding inclined surface 304 , and the third guiding inclined surface 304 is used to guide the movement of the latch 11 toward the first limiting block 4 , so as to improve the movement accuracy of the latch 11 .

[0074] The panel 1 and the grid 3 are fixed by the latch 11 and the buckle 12, which ensures that they are easy to disassemble and assemble and convenient for maintenance while ensuring effective fixation. After the panel 1 and the grid 3 are separated, the panel 1 and the grid 3 can be efficiently assembled by the latch 11 and the buckle 12, and the fixing stability is good. After the panel 1 and the grid 3 are fixed by the latch 11 and the buckle 12, no screws are required to assist in fixing, so that the assembly efficiency of the panel 1 and the grid 3 is high.

[0075] In some embodiments, Figure 8 As shown, the aforementioned filter assembly may also include a second limiting structure, which is used to keep the panel 1 and the frame 3 relatively fixed in the direction d in which the frame is inserted into the external air outlet track and in the direction e in which the frame exits the external air outlet track.

[0076] In the above example, by setting up the second limiting structure, the stability of the panel 1 pushing the frame 3 to insert into and exit the external air outlet track 7 can be improved, preventing the panel 1 from shaking during the process of pushing the frame 3.

[0077] In some embodiments, Fig. 9As shown, the aforementioned second limiting structure may include a second limiting block 5, and the second limiting block 5 is arranged on one of the panel 1 and the grid 3. Among them, the component in which the second limiting block 5 is arranged in the panel 1 and the grid 3 is taken as the fifth component, and the other is taken as the sixth component. When the buckle 12 is engaged with the card slot 13, the second limiting block 5 abuts against the sixth component along the third direction to fix the sixth component on the fifth component along the third direction. Among them, the third direction is the direction d in which the grid is inserted into the external air outlet track or the direction e in which the grid exits the external air outlet track.

[0078] Among them, in order to reduce wear, such as Fig. 9 As shown, the sixth component may be provided with a third stopper 6, and when the buckle 12 is engaged with the slot 13, the second stopper 5 abuts against the sixth component through the third stopper 6. Since the second stopper 5 does not directly contact the sixth component, the abutment wear on the sixth component can be reduced.

[0079] It should be noted here that the second limiting block 5 and the third limiting block 6 mentioned above can both be ribs.

[0080] For ease of understanding, Fig. 9 As shown, the following is a specific example in which the second limit block 5 is set on the grid 3, and the third direction is the direction e in which the grid exits the external air outlet track. At this time, the grid 3 is the fifth component mentioned above, the panel 1 is the sixth component mentioned above, the third limit block 6 is set on the panel 1, and the third direction is the direction e in the figure. When the buckle 12 is engaged with the slot 13, the second limit block 5 is against the panel 1 through the third limit block 6 along the direction e, and the second limit block 5 fixes the panel 1 on the grid 3 through the third limit block 6 along the direction e.

[0081] In some embodiments, Fig.10 and Fig.11 As shown, the aforementioned grid 3 has a plug-in section 33, and the plug-in section 33 has the aforementioned second end 32. The grid 3 has a windward surface 305 and a leeward surface 306. The plug-in section 33 is an arc-shaped section that bends toward the leeward side of the grid 3. Figure 1 and Fig.10 The portion within the dotted line frame on the middle grid is the plug-in section 33 .

[0082] In the above example, by designing the plug-in section 33 as an arc section, the defect of large friction resistance caused by direct contact between the existing straight plug-in section 33 and the external arc track is avoided, the friction force of the grid 3 inserting and withdrawing from the external air outlet track 7 can be reduced, the resistance is reduced, and the filter assembly is easier to disassemble and assemble.

[0083] In the above example, if Fig.15As shown, the aforementioned grid 3 also has a straight section 34, which is connected to the side of the plug-in section 33 away from the second end 32, and the projection length of the plug-in section 33 on the plane where the straight section 34 is located is L1, 30 mm≤L1≤50 mm.

[0084] In the above example, by making the projection length L1 of the plug section 33 within the range of 30 mm to 50 mm, it is beneficial for the plug section 33 to be plugged into the tuyere track 7. It should be noted that in actual applications, the optimal projection length of the plug section 33 can be selected according to the curvature of the external tuyere track 7.

[0085] It should be noted here that the grid in the prior art generally adopts a straight design, which can reduce the difficulty of mold design and production, and is also conducive to force conduction during disassembly and assembly. The existing integrated design of the grid and the panel, the grid and the panel are integrally injection molded, the injection molding material used is relatively hard, and the stress generated by deformation is relatively large. In order to avoid popping out after assembly, a section of the grid close to the panel must be made into an arc shape to prevent the external arc tuyere track from being illuminated. The grid 3 in the utility model can be disassembled, so the grid 3 can be processed separately, and the material thickness of the grid 3 can be further reduced after disassembly. Specifically, because the fluidity of the material is different, the grid 3 after disassembly can be processed separately with a material with better fluidity for injection molding. Because the appearance performance of the material is not good, it cannot be used on the existing grid integrally molded with the panel. When the grid 3 after disassembly is injected with the material with better fluidity, the material thickness can be reduced, and the thickness of the grid 3 can be reduced to 1.5-2mm, which further increases the softness of the grid 3 and makes the disassembly and assembly of the filter assembly smoother and more convenient. In addition, since the mesh frame 3 is more flexible, the straight line segment 34 can be extended to the first end 31 to reduce the difficulty of mold design and production.

[0086] In some embodiments, Fig.11 As shown, the aforementioned second end 32 has a second guide slope 331 on the windward side 305 of the grid 3, and the second guide slope 331 is used to guide the insertion of the plug-in section 33 into the external air outlet track 7, so as to further reduce the friction force of the grid 3 when inserting and withdrawing from the external air outlet track 7, further reduce the resistance, and make the filter assembly easier to disassemble and assemble.

[0087] Among them, Figure 8 As shown, the second end 32 has chamfers on both sides in the width direction of the grid 3 to further guide the insertion of the plug-in section 33 into the external air outlet track 7, so that the filter assembly can be better disassembled and assembled.

[0088] In some embodiments, the present invention further provides a household appliance, which may include any of the above-mentioned filter screen components, wherein the household appliance may be an air conditioner or a dehumidifier.

[0089] In the above example, because the household appliance adopts the above filter assembly, the panel 1 and the grid 3 are detachably connected, so that the panel 1 and the grid 3 can be processed separately. Compared with the prior art method of integrally forming the panel 1 and the grid 3, the panel 1 in the utility model can be processed separately, so the processing difficulty is lower, which can effectively reduce the scrapping of the panel 1 due to appearance defects, avoid unnecessary waste, improve production efficiency, and reduce production costs.

[0090] In some embodiments, Figures 12 to 15 As shown, when the grid 3 has a plug-in section 33, and the plug-in section 33 is an arc section that bends toward the leeward side 306 of the grid 3, the aforementioned household appliance also has an air outlet and an air outlet track 7 arranged at the air outlet. Among them, the air outlet track 7 can be an arc track. Or the air outlet track 7 is formed by connecting two or more arc tracks in sequence, and the bending directions of each arc track are consistent. The aforementioned grid 3 is used to drive the filter net to be inserted into the air outlet track 7 to filter the wind flowing through the air outlet. Among them, the air outlet track 7 has a first surface 71 and a second surface 72 opposite to each other, the first surface 71 is opposite to the windward side 305 of the grid 3, and the second surface 72 is opposite to the leeward side 306 of the grid 3. The interval between the first surface 71 and the second surface 72 is L2.

[0091] The aforementioned grid 3 also has a straight section 34, which is connected to the side of the plug-in section 33 facing away from the second end 32. The surface of the straight section 34 located on the windward surface 305 is taken as the first surface. The distance between the aforementioned second end 32 and the first surface is L3, and L3 is smaller than L2. This is to avoid the difficult installation situation in which the straight section 34 directly contacts the air outlet track 7 when the grid 3 is inserted and pushed, thereby generating huge pushing resistance. The friction between the grid 3 and the air outlet track 7 can be reduced, and the insertion and pushing resistance of the grid 3 can be reduced, so that the filter assembly can be better disassembled and assembled.

[0092] It should be noted here that: in a specific application example, the aforementioned L3 is 7 mm and L2 is 5 mm.

[0093] For ease of understanding, the overall structure of the utility model is described below, and its working principle is explained.

[0094] The filter assembly is divided into a panel 1 and a mesh frame 3. The front of the panel 1 is designed with a handle 2 for disassembly and assembly, which provides a handhold and force point for disassembly and assembly of the filter assembly. The back of the panel 1 is designed with buckles 12 and latches 11 for fixing the mesh frame 3. The panel 1 is designed with three latches 11 on both sides of the width direction of the filter assembly, and two buckles 12 are designed in the middle. Eight matching holes are designed on the back of the mesh frame 3, including six second through holes 302 that match the corresponding latches 11 and two first through holes 301 that match the corresponding buckles 12. The mesh frame 3 is assembled on the panel 1 by sliding along the width direction of the filter assembly. No screws are required to fix the mesh frame 3 and the panel 1, which facilitates the subsequent maintenance and replacement of the filter part, and improves the assembly efficiency between the mesh frame 3 and the panel 1. Among them, the direction in which the clip 12 is inserted into the slot 13 is perpendicular to the direction in which the grid 3 is inserted into or withdrawn from the external air outlet track 7, thereby avoiding the grid 3 from being disengaged during the disassembly and assembly process, and ensuring the fixing stability between the grid 3 and the panel 1.

[0095] After the panel 1 and the grid 3 are separated, the panel 1 avoids the appearance defects in manufacturing caused by the narrow and long ribs of the grid 3, improves the qualified rate of the product, reduces the production difficulty and production cost, and at the same time, the panel 1 retains the performance that meets the secondary treatment such as spraying and electroplating. Because the grid 3 does not need to be subjected to secondary treatment, the grid 3 does not need to use materials with better performance and higher hardness after separation, and the grid 3 can use materials such as PP with better flexibility.

[0096] The panel 1 is fixed to the back of the grid 3 by a latch 11 and a buckle 12, and the buckle 12 effectively limits the displacement of the grid 3 in the assembly direction. In order to facilitate the grid 3 to be installed in the panel 1, a first guide slope 303 is designed on the grid 3. When the grid 3 needs to be removed from the panel 1, it is only necessary to apply a certain degree of force in the opposite direction of the assembly so that the buckle 12 is deformed and moved upward, and the grid 3 can be removed by releasing the limit. At the same time, the front of the grid 3 is designed with ribs to limit the direction d in which the grid is inserted into the external air outlet track and the direction e in which the grid is withdrawn from the external air outlet track, so as to avoid the grid 3 being difficult to install due to deformation and shaking during the insertion process of the external air outlet track 7.

[0097] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0098] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the utility model, and these improvements and variations should also be regarded as the protection scope of the utility model.
