[0041] Reference Figure 1-Figure 8 , which is an embodiment of the lint filter device 200 of the utility model. The lint filter device 200 of the utility model is set in a clothes processing device such as a dryer or a washer-dryer, and is used to capture and intercept lint, fluff and other tiny particles generated during the drying process of clothes, and prevent lint and the like from entering the internal system of the device and affecting its normal operation and performance.

[0042] See also Figure 4 The lint filtering device 200 includes a first filter 210 and an air inlet cover 220 .

[0043] The first filter 210 includes a first frame 211 having a box shape.

[0044] The top of the first frame 211 is a first air inlet. Specifically, the top surface of the first frame 211 is open to allow drying air to flow in.

[0045] The first air outlet is formed on the side and bottom of the first frame 211, and a filter is provided on the first air outlet (the filter is not shown in the figure). In this embodiment, the side and bottom of the first frame 211 are surrounded by strip ribs, and the grille formed between the strip ribs forms the first air outlet.

[0046] The interior of the first frame 211 forms a lint filtering chamber.

[0047] The air inlet cover 220 is disposed on the first air inlet of the first filter 210 to cover the first air inlet, and a plurality of air inlet holes 2221 are provided on the air inlet cover 220. The air inlet holes 2221 are evenly distributed on the air inlet cover 220 to ensure that the drying air can evenly enter the first filter 210.

[0048] When the dryer is running, Figure 8 As shown, the drying air enters the first filter 210 through the air inlet hole 2221 on the air inlet cover 220. After being filtered by the filter, the lint impurities are collected in the lint filter cavity. The filtered air is discharged from the first air outlet on the side and bottom and enters the air duct in the dryer.

[0049] In the above-mentioned lint filtering device 200, the side and bottom of the first filter 210 are both filtering areas, which effectively increases the filtering area, can effectively intercept more lint and impurities, and improves the filtering efficiency. In addition, the first filter 210 adopts a box-shaped structure, which not only ensures the stability of the device, but also increases the air intake volume due to the large overall inner cavity capacity, thereby improving the drying efficiency of the dryer.

[0050] In this embodiment, the first filter 210 has an arc-shaped bottom surface and two opposite side surfaces, and the arc-shaped bottom surface and the two opposite side surfaces are provided with filter screens. The bottom of the first filter 210 is an arc-shaped structure, and when air flows in from the top, the air is allowed to flow smoothly along the arc-shaped bottom surface to both sides, thereby ensuring more efficient air circulation, optimizing the air flow path, and improving the filtering effect.

[0051] In another embodiment, the first filter may also be a structure with four sides and a bottom.

[0052] The lint filter 200 is mounted on the front side plate 100 of the clothes dryer, and a receiving cavity 110 is provided on the front side plate 100, and the lint filter is mounted in the receiving cavity 110. The receiving cavity 110 is opened along the inner side of the clothing inlet of the front side plate 100, so the top of the lint filter 200 is a roughly arc-shaped structure to match the shape of the clothing inlet.

[0053] In order to facilitate the removal of the lint filter 200 from the receiving cavity 110 of the front side plate 100, Figure 4 As shown, a first buckle structure 2222 is provided on the air inlet cover 220, and the first buckle structure 2222 is used to apply a pulling force from bottom to top.

[0054] Specifically, the first hand-grip structure 2222 includes two hand-grip grooves opened in the middle of the air inlet cover 220 . The two hand-grip grooves are approximately semicircular. Two fingers can be inserted into the two hand-grip grooves respectively to remove the lint filtering device 200 from the accommodating cavity 110 .

[0055] In this embodiment, a slide groove structure is provided between the first frame 211 and the air inlet cover 220 , and the air inlet cover 220 can be drawn and covered on the first frame 211 through the slide groove structure.

[0056] Specifically, Figure 6 As shown, the air inlet cover 220 is provided with sliding grooves at the bottom of both ends along its length direction, and convex ribs 2111 are provided at both ends of the first frame 211 corresponding to the sliding grooves. The convex ribs 2111 are slidably arranged in the sliding grooves, so that the air inlet cover 220 and the first frame 211 are assembled together, and the air inlet cover 220 can be pulled and pulled along its width direction.

[0057] The slide groove on the air inlet cover 220 is open at one end and closed at the other end, so that the air inlet cover 220 can only be pulled from one side, and the air inlet cover 220 and the first filter 210 can be completely separated, making it easy to clean the first filter 210.

[0058] In order to facilitate the removal of the air inlet cover 220 and cleaning the inside of the first filter 210, a second buckle structure is provided on the upper side of the first frame 211. The second buckle structure is used to apply a pulling force along the width direction of the first frame 211 to facilitate the separation of the air inlet cover 220 and the first filter 210.

[0059] Specifically, Figure 7 As shown, the second hand-locking structure includes a hand-locking cover 240, and the hand-locking cover 240 is fixed to the first frame 211 through a buckle structure. The second hand-locking structure is arranged in the middle of the first frame 211 to ensure uniform force application.

[0060] Furthermore, the bottom surface of the handle cover 240 has a concave hand groove, and the top edge of the first frame 211 has a flange structure, which has a notch groove 2112, and a claw 2113 is provided at the notch groove 2112. A clamping hole is provided on the handle cover 240, and the handle cover 240 is installed in the notch groove 2112 through the clamping hole and the claw 2113.

[0061] In this embodiment, in order to facilitate manufacturing, the air inlet cover 220 is composed of two parts: an air inlet cover frame 221 and a cover plate 222 fixed to the air inlet cover frame 221. The cover plate 222 is provided with an air inlet hole 2221, and the air inlet cover frame 221 is connected to the first frame 211. The air inlet cover frame 221 and the cover plate 222 can be made into an integral structure by a cladding process.

[0062] In another embodiment, the air inlet cover 220 may also be an integral piece.

[0063] In this implementation, if Figure 3 and Figure 4 As shown, the lint filtering device 200 further includes a second filter 230. The first filter 210 is disposed in the second frame, that is, the first filter 210 forms an inner filtering structure, and the second filter 230 forms an outer filtering structure, and filtering is performed through the inner and outer double-layer filter screens, further improving the filtering effect of the air.

[0064] Specifically, the second filter 230 includes a second box-shaped frame, the top of the second frame is a second air inlet, the side and bottom of the second frame are formed with second air outlets, and a filter is provided on the second air outlet.

[0065] The structure of the filtering portion of the second filter 230 is substantially the same as that of the first filter 210 .

[0066] During installation, the first filter 210 and the air inlet cover 220 are first assembled together through the slide groove structure, and then the second filter 230 is installed in the installation cavity of the front side plate 100, and finally the first filter 210 and the air inlet cover 220 are installed in the second filter 230. The second filter 230 and the first filter 210 can also be fixed by a buckle structure.

[0067] The utility model also includes a clothes dryer, which has a front side panel 100 and an internal drying air duct, and a receiving chamber 110 is provided at the inner bottom of the clothes loading port on the front side panel 100, and a lint filter device is installed in the receiving chamber 110. The side and bottom surfaces of the lint filter device 200 are spaced from the cavity wall of the receiving chamber 110 to ensure that air can enter the air duct from the side and bottom surfaces of the lint filter device 200.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
