[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] See also Figures 1 to 9 , this embodiment provides a clothing processing device, which can be a washing machine with a drying function, or a washer-dryer or a clothes dryer. The clothing processing device includes an outer drum 110, an inner drum and a lint cleaning device. The inner drum is rotatably arranged in the outer drum 110, and the inner drum is used to hold clothes. The outer drum 110 has an air inlet and an air outlet. The lint cleaning device includes a filter 10. The filter 10 is arranged in the air duct 120. The air duct 120 has an air inlet and an air outlet. The windward side of the filter 10 faces the air inlet to filter the air flow for lint. The air outlet is connected to the air inlet, and the air inlet is connected to the air outlet. The airflow flowing out of the air outlet enters the air duct 120 from the air inlet and then flows from the air outlet into the air inlet of the outer drum 110, realizing air flow circulation. Figure 1 The middle arrow indicates the direction of air flow. During the air circulation process, the filter element 10 filters the lint in the air flow, and the inner drum rotates around its own axis to drive the clothes to tumble, thereby drying the clothes.

[0043] The air duct 120 is provided with a fan 130 that guides airflow from the air inlet to the air outlet. The fan 130 can be provided at any position in the air duct 120. In this embodiment, the air duct 120 includes a first air duct 121 and a second air duct 122. The first air duct 121 is provided on the air inlet side of the fan 130 and has an air inlet. The second air duct 122 is provided on the air outlet side of the fan 130 and has an air outlet.

[0044] In this embodiment, the first air duct 121 is arranged at the rear of the outer cylinder 110 and extends basically in the vertical direction, the air flow outlet is arranged at the bottom of the outer cylinder 110, the air inlet is located at the bottom end of the first air duct 121, the fan 130 is arranged at the top of the first air duct 121, and the second air duct 122 is arranged at the top of the outer cylinder 110 and extends basically in the horizontal direction.

[0045] The humid air flow from the inner tube flows out of the outer tube 110 from the air outlet, enters the first air duct 121 through the air inlet, and since the first air duct 121 basically extends in the vertical direction, it condenses the air flow. The condensed water flows downward along the first air duct 121 and can be discharged from the drain outlet of the outer tube 110 or collected in the water collection box.

[0046] The airflow passes through the fan 130 and enters the second air duct 122. A heat exchanger is provided in the second air duct 122 to heat the airflow so that the high-temperature airflow enters the airflow inlet of the outer tube 110 from the air outlet again. The heat exchanger can be an existing heating tube or heating wire.

[0047] The lint cleaning device also includes a spray assembly 20, which includes a spray element 21. The spray element 21 is disposed on the leeward side of the filter element 10 and is capable of spraying water toward the leeward surface of the filter element 10. The spray element 21 rotates about a first axis under the reverse action of the spraying water flow. Airflow entering from the air inlet is filtered by the filter element 10, and lint in the airflow adheres to the filter element 10. To prevent the filter element 10 from clogging, after a period of use, the spray element 21 sprays water toward the leeward side of the filter element 10, causing the lint to fall from the windward side of the filter element 10, thereby flushing the lint from the filter element 10. The spray element 21 rotates about the first axis under the reverse action of the spraying water flow, expanding the cleaning coverage area and thereby cleaning the lint from the filter element 10 from multiple angles, resulting in more thorough cleaning. This eliminates the need for a power-driven spray element 21, saving energy and reducing the risk of failure.

[0048] The filter element 10 is positioned between the air inlet and the fan 130 to prevent lint from entering the fan 130. The filter element 10 can be positioned closer to the air inlet or closer to the fan 130. In this embodiment, the filter element 10 is positioned away from the air inlet and closer to the fan 130. The filter element 10 is positioned near the top of the first air duct 121, facilitating installation of the spray assembly 20.

[0049] The air inlet is located below the filter element 10. At least a portion of the air duct 120 extends vertically between the filter element 10 and the air inlet. Water sprayed from the spray element 21 impacts the lint on the filter element 10, then flows down the first air duct 121 to the drain outlet of the outer cylinder 110, where it is discharged or collected in a water collection box.

[0050] The spray element 21 is positioned above the filter element 10, allowing the spray water to flow downward under its own gravity to impact the filter element 10. Specifically, a pipe connector 140 is provided between the fan 130 and the first air duct 121. At least a portion of the spray assembly 20 is located within the pipe connector 140, facilitating installation of the spray assembly 20. In this embodiment, the top of the first air duct 121 is a circular opening to facilitate installation of the filter element 10. The pipe connector 140 is a circular connector to facilitate installation of the spray element 21.

[0051] The spray assembly 20 also includes a water supply pipe 23, which is used to supply water to the spray element 21. The pipe connector 140 is provided with a through hole that allows the water supply pipe 23 to pass through. The water supply pipe 23 and the pipe connector 140 can be sealed by a sealing ring. For example, a water inlet valve is provided on the water supply pipe 23. When the water inlet valve is opened, the water supply pipe 23 supplies water to the spray element 21, and the spray element 21 rotates around the first axis under the reverse action of the spraying water flow; when the water inlet valve is closed, the water supply pipe 23 no longer supplies water to the spray element 21, and the spray element 21 stops spraying and stops rotating. The opening of the water inlet valve can be adjusted, thereby changing the water inlet pressure. The greater the water inlet pressure, the greater the rotation speed of the spray element 21 and the better the spraying effect.

[0052] The function of the filter element 10 is to filter the airflow in the air duct 120. Therefore, the filter element 10 is intercepted in the air duct 120 so that all airflow passing through the air duct 120 can be filtered by the filter element 10. The filter element 10 includes a frame and a filter screen arranged on the frame. The filter screen extends along the first plane, and the first axis is perpendicular to the first plane. The spray element 21 rotates around the first axis and can fully cover the area where the filter screen is located to ensure the cleaning effect. The filter screen can be provided with one layer or multiple layers. For example, the filter screen is provided with two layers, and the two layers of filter screens are arranged at intervals along the flow direction of the airflow to achieve double-layer filtration and improve the lint filtering effect. The spray element 21 can spray the double-layer filter screen at the same time when spraying.

[0053] In other embodiments, the filter is curved to increase the contact area with the airflow and improve the filtering effect. One end of the filter is close to the spray element 21 and the other end is away from the spray element 21, or the side of the filter close to the spray element 21 is concave inward to form a curved surface.

[0054] The spray assembly 20 also includes a support shaft 22 extending along a first axis. The support shaft 22 is hollow inside to form a water inlet chamber 221. The spray element 21 is hollow inside to form a water storage chamber 201. The spray element 21 includes a rotating shaft 211, which is rotatably plugged into the support shaft 22. The water inlet chamber 221 is connected to the water storage chamber 201. The support shaft 22 supports the spray element 21, and the spray element 21 rotates around the support shaft 22. One end of the water inlet chamber 221 is a water inlet, and the other end is a water outlet. The water inlet is connected to the water supply pipe 23, and the rotating shaft 211 is connected to the water outlet. The rotating shaft 211 can be plugged into the support shaft 22, or the support shaft 22 can be plugged into the rotating shaft 211.

[0055] In this embodiment, at least a portion of the rotating shaft 211 is inserted into the support shaft 22, and a sealed connection is formed between the outer wall of the rotating shaft 211 and the inner wall of the support shaft 22. Water entering from the water supply pipe 23 passes through the support shaft 22 to the rotating shaft 211, and then enters the spray element 21. The sealed connection between the outer wall of the rotating shaft 211 and the inner wall of the support shaft 22 prevents water leakage.

[0056] It can be that a sealing ring is sleeved on the outer wall of the rotating shaft 211, and the sealing ring abuts against the inner wall of the supporting shaft 22 to achieve sealing. Specifically, a groove is provided on the outer wall of the rotating shaft 211, and the sealing ring is stuck in the groove. Figure 9 As shown, in this embodiment, a plurality of annular protrusions 2111 are provided on the outer wall of the rotating shaft 211, and the annular protrusions 2111 abut against the inner wall of the support shaft 22. The annular protrusions 2111 can be integrally formed with the rotating shaft 211, which facilitates processing and production. The annular protrusions 2111 abut against the inner wall of the support shaft 22 to achieve sealing, reduce the number of parts, and facilitate assembly.

[0057] Optionally, a limiting groove is provided on the inner wall of the support shaft 22, and the annular protrusion 2111 is snapped into the limiting groove, which can achieve both sealing and clamping and limiting. In this embodiment, there are two annular protrusions 2111, and two corresponding limiting grooves are provided.

[0058] As the rotating shaft 211 is inserted into the support shaft 22, the cross-sectional area of the rotating shaft 211 gradually decreases to form a tapered surface, facilitating smooth insertion of the rotating shaft 211 into the support shaft 22. Optionally, a stopper 223 is protruded from the inner wall of the support shaft 22. The stopper 223 is arranged in an annular shape around the axial direction of the support shaft 22. After the rotating shaft 211 is inserted into the support shaft 22, the end of the rotating shaft 211 abuts against the stopper 223. The stopper 223 limits the rotating shaft 211 and can block the gap between the rotating shaft 211 and the support shaft 22, thus providing a certain sealing effect.

[0059] In this embodiment, the rotating shaft 211 is engaged with the support shaft 22 for easy installation and removal. For example, a limiting protrusion 222 is provided on the outer wall of the support shaft 22. The spray element 21 also includes an elastic snap 213, one end of which is connected to the rotating shaft 211, and the other end of which is engaged with the limiting protrusion 222. By engaging the elastic snap 213 with the limiting protrusion 222, the rotating shaft 211 and the support shaft 22 are limited, facilitating installation and removal. Because the limiting protrusion 222 is provided, the elastic snap 213 can rotate around the limiting protrusion 222, thereby not affecting the rotation of the rotating shaft 211 relative to the support shaft 22. For example, a slot is provided on the inner wall of the support shaft 22, and a locking protrusion is provided on the outer wall of the rotating shaft 211, which is engaged with the slot.

[0060] The spray element 21 also includes a spray arm 212. The end of the rotating shaft 211 away from the support shaft 22 is connected to the spray arm 212. The spray arm 212 is provided with a plurality of spray holes 2121 that communicate with the water storage chamber 201. The plurality of spray holes 2121 are spaced apart along the length of the spray arm 212. Water entering from the water supply pipe 23 passes through the support shaft 22 and reaches the rotating shaft 211, thereby entering the spray element 21. The water then flows through the rotating shaft 211 into the spray arm 212 and is sprayed from the spray holes 2121, thereby spraying water onto the filter element 10.

[0061] The spraying direction of the spray holes 2121 can be set according to actual needs, and at least some of the spray holes 2121 are directed toward the filter element 10 to spray water toward the filter element 10. The spray holes 2121 can also be set at an angle. Figure 8 As shown, at least one spray hole 2121 sprays water toward one side of the spray arm 212, and the sprayed water flow impacts the inner wall of the air duct 120, so that the spray element 21 rotates around the first axis under the reverse action of the spray water flow. For example, a first spray hole is provided at the bottom of one end of the spray arm 212, and a second spray hole is provided at the bottom of the other end of the spray arm 212. The first spray hole and the second spray hole spray water toward both sides of the spray arm 212 respectively, and the spray directions are opposite. The spray hole 2121 can be rectangular, circular, elliptical or other shapes. The number of spray holes 2121 is determined by the flow rate, hole size and area of the filter element 10, and can be set according to actual needs.

[0062] The spray arm 212 can extend in a straight line radially along the rotating shaft 211, or it can extend in a curved line. The spray arm 212 can be integrally formed or removable. In this embodiment, the spray arm 212 comprises a first housing and a second housing that interlock. The first housing is connected to the rotating shaft 211, and the second housing defines a spray hole 2121. The first and second housings can be connected by snaps or screws for easy disassembly and cleaning.

[0063] The above-mentioned lint cleaning device can be applied not only to clothing processing equipment with a drying function, but also to other equipment that needs to filter lint.

[0064] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention.
