[0040] As Figures 1-2 In the embodiment of the present application, a filter unit 2 and a suction device 4 and an optical sensor 5 are arranged inside the cleaning structure, the suction device 4 is used to perform a suction action, so that the lint is absorbed in the filter channel; of course, in the embodiment, the cleaning structure can be provided with multiple and arranged at different positions of the clothes processing equipment, or can be arranged in the gap between the inner wall 1 of the inner drum and the water-pushing blade and / or the lifting rib, and other schemes, which will not be listed one by one here, and only the above-mentioned drawing examples are discussed:

[0041] The cleaning structure of the laundry treating apparatus is provided in the embodiment, taken the drum laundry treating apparatus as an example, the drum laundry treating apparatus includes a cabinet, a drum arranged in the cabinet, and a lifting rib arranged in the drum.

[0042] The cleaning structure, detachably arranged on the inner wall 1 of the inner drum, further includes a filtering unit 2, the filtering unit 2 includes a filtering cavity 23, and the filtering cavity 23 is provided with an opening, the cavity wall of the filtering cavity 23 is at least partially surrounded by a first filter screen 21, and the opening of the filtering cavity 23 is provided with a second filter screen 22, the first filter screen 21 is a fine filter screen, the second filter screen 22 is a coarse filter screen, the mesh aperture of the first filter screen 21 is smaller than the mesh aperture of the second filter screen 22, so as to avoid the lint flowing into the space between the inner drum and the outer drum through the first filter screen 21.

[0043] Further, the cleaning structure includes a suction device 3, the filtering unit 2 is arranged at the suction end 31 of the suction device 3, and under the action of the suction device 3, the fluid in the inner drum passes through the filtering unit 2. The fluid includes air flow and water flow.

[0044] Specifically, the fluid enters the filtering cavity 23 through the opening of the filtering unit 2, and the lint is accumulated at the second filter screen 22 under the action of the suction device 3.

[0045] During the operation of the laundry treating apparatus, under the condition that the suction device is not working, the lint will be accumulated at the second filter screen 22 due to the centrifugal force, so as to avoid flowing out through the first filter screen 21.

[0046] In the preferred embodiment of the present embodiment, the first filter screen 21 and the second filter screen 22 are attached to the lifting rib, or in the pulsator washing machine, the first filter screen 21 and the second filter screen 22 are arranged on the inner wall and / or the outer wall of the water-pushing blade, and the suction device 3 is arranged below the second filter screen 22. In this way, the lint in the inner drum can be sucked into the filtering cavity 23 by the force provided by the suction device 3.

[0047] The setting area of the first filter screen 21 is greater than the setting area of the second filter screen 22 in the cleaning structure; the second filter screen 22 is used for collecting the lint in the inner drum in the filtering cavity 23 surrounded by the first filter screen 21 and the second filter screen 22, so as to avoid the lint flowing into the space between the inner drum and the outer drum, thereby making it difficult to clean.

[0048] The suction end 31 of the suction device 3 is provided with the first filter screen 21, so as to prevent the lint from flowing into the suction device 3.

[0049] The suction end 31 of the suction device 3 is arranged opposite to the opening of the filtering cavity 23.

[0050] The filtering cavity 23 is surrounded by the first filter screen 21 extending from the inner wall 1 of the inner drum to the side close to the axis of the inner drum in the radial direction, and the opening of the filtering cavity 23 is arranged at the side close to the axis of the inner drum. The suction device 3 is arranged at the side of the filtering unit 2 close to the inner wall 1 of the inner drum.

[0051] In the laundry treating apparatus, for example, the drum washing machine, the cleaning structure can be installed in the lifting rib to prevent lint in the inner drum from flowing into the outer drum.

[0052] The cleaning structure further comprises an optical sensor 4 arranged in the cleaning structure, and the filtering unit 2 is arranged on the optical sensor 4. The optical sensor 4 is used to emit a light beam into the filtering cavity 23 to detect the amount of lint accumulated on the first filter screen 21 or the amount of lint accumulated in the filtering cavity 23.

[0053] The suction device 3, the filtering unit 2, and the optical sensor 4 together constitute the cleaning structure. In the drum laundry treating apparatus or the pulsator laundry treating apparatus, at least one cleaning structure is arranged, and in the preferred embodiment, one cleaning structure is arranged in each lifting rib or paddle.

[0054] The suction device 3 is arranged in close contact with the inner wall 1 of the inner drum at the side opposite to the suction end 31. The other surfaces of the suction device 3 can also have a suction effect. The suction device 3 is detachably connected to the inner wall 1 of the inner drum.

[0055] In the preferred embodiment, the cleaning structure comprises an inlet end and an outlet end. The inlet end and the outlet end of the protruding structure through which the air flow and / or the water flow pass in sequence together constitute a filtering channel arranged in the protruding structure. The inlet end of the protruding structure is the inlet end of the filtering channel, and the outlet end of the protruding structure is the outlet end of the filtering channel.

[0056] The laundry treating apparatus comprises paddles or lifting ribs, and the cleaning structure can be the paddles or the lifting ribs. For example, the suction device 3 and the filtering unit 2 are arranged in the paddle, the filtering unit 2 is provided with a filtering cavity 23, the opening of the filtering cavity 23 is arranged on the side of the paddle close to the axis of the inner drum, and the cavity wall of the filtering cavity 23 can be arranged with a gap from the side wall of the paddle. However, in the preferred embodiment, part of the cavity wall of the filtering cavity 23 is the side wall of the paddle, so as to prevent the lint from flowing into the gap between the cleaning structure and the lifting rib.

[0057] The optical sensor 4 is further arranged in the cleaning structure to emit light into the annular filtering channel.

[0058] Specifically, the optical sensor 4 can at least have a communication connection relationship with the controller of the laundry treating apparatus.

[0059] An optical sensor is a device that uses light to detect and measure the existence, distance, shape, color, and other characteristics of an object.

[0060] The core working principle of the optical sensor is to obtain information by emitting a light source and detecting the returned or transmitted light signal.

[0061] The optical sensor typically contains a light source, commonly an LED (Light Emitting Diode) or a laser diode. This light source emits a beam of light that is directed onto the object being measured. This is directed onto the second filter, which detects the accumulation of lint.

[0062] The emitted light beam interacts with the object in various ways, such as reflection, refraction, scattering, or absorption. The specific interaction depends on the surface properties of the object and the characteristics of the light source.

[0063] Receiving the light signal: The sensor also contains a photodetector (such as a photoresistor, photodiode, or phototransistor) that receives the light signal (reflected light) returned from the object or transmitted through the object.

[0064] Signal processing: The received light signal is converted into an electrical signal and undergoes amplification, filtering, and processing, ultimately outputting an interpretable signal (such as voltage, current, or digital signal).

[0065] Transmissive sensor:

[0066] The light source and receiver are located on opposite sides of the object. For example, the light source is placed on one side of the suction device, and the receiver is placed at the first filter, so that the light source and receiver are on the same central axis. When the light is emitted, the lint will block part of the light, and the receiver will detect the change in light intensity, thereby achieving detection. If the penetration is strong, it means that the lint accumulation is small. If the light source cannot penetrate the second filter, it means that the lint accumulation is large and needs to be cleaned.

[0067] A sensor that can detect the change in brightness of the second filter 22 surface can also be provided to determine the accumulation of lint. When the second filter 22 surface is detected to be dark, it means that the lint accumulation is large; when the second filter 22 surface is detected to be bright, it means that the lint accumulation is small.

[0068] When the lint accumulation is large, the user is prompted to clean.

[0069] Taking a pulsator laundry treatment device as an example, the laundry treatment device has an inner drum wall and a water-pushing blade. The water-pushing blade is provided with a water inlet at the top and a water outlet at the side.

[0070] A suction device is detachably installed in the water-pushing blade.

[0071] A first filter 21 and a second filter 22 are provided. The first filter 21 is arranged at the water inlet at the top of the water-pushing blade, and the second filter 22 is arranged at the water outlet at the side of the water-pushing blade.

[0072] The first filter 21 and the second filter 22 are provided with mesh holes. The mesh hole diameter of the first filter 21 is smaller than the mesh hole diameter of the second filter 22.

[0073] The water outlet of the water deflector is an arc shape that gradually narrows towards the center of the water deflector along the bottom of the water deflector, and the water inlet of the water deflector is an arc shape that extends from the center of the water deflector to both sides.

[0074] The suction device 3 includes a first surface that is attached to the inner drum wall of the laundry treatment equipment and a second surface on which a second filter screen is arranged extending towards the water outlet of the water deflector.

[0075] An optical sensor 4 is also arranged in the water deflector for detecting lint accumulation between the first filter screen 21 and the second filter screen 22.

[0076] The material and functional design of the suction device 3 takes into account durability, ease of cleaning, and safety.

[0077] The housing is made of high-strength, wear-resistant materials such as ABS or polypropylene, ensuring that the device is lightweight and robust.

[0078] Or use silica gel or other high-wear rubber materials to provide good sealing performance, prevent water flow, and ensure suction effect. The suction device power supply method can be battery-powered, and the suction device at least has the function of wireless communication with the controller, so that when the suction device 3 needs to perform a suction action, it can be controlled by a remote controller or other controller.

[0079] If necessary, stainless steel or aluminum alloy can be used as the internal support structure to increase the durability and stability of the device.

[0080] The suction device 3 has strong suction: equipped with a high-efficiency motor that provides sufficient suction to effectively suck up lint and other debris in the inner drum of the laundry treatment equipment.

[0081] Multiple suction heads: provide different shapes and sizes of suction heads to adapt to various shapes and cleaning needs of the inner drum of the laundry treatment equipment. Special designed slim suction head can reach deep into the corners of the laundry treatment equipment that are difficult to access.

[0082] The suction device 3 is detachably arranged with the inner drum wall, and is also detachably arranged with the entire cleaning structure, which is beneficial for cleaning and ensures hygiene after each use.

[0083] High-efficiency filters can also be provided to prevent lint and dust sucked in from being re-emitted into the air, ensuring cleaning effect.

[0084] Noise control: adopt noise reduction design to reduce noise when the motor is working, improve user experience.

[0085] The optical sensor 4 realizes automatic cleaning reminder of the cleaning structure, and the optical sensor 4 detects the accumulation of lint through the emission of light beams and reminds the user when to clean.

[0086] The suction device 3 aims to provide an effective and convenient cleaning solution, helping the user to keep the inner drum of the laundry treatment apparatus clean, prolonging the service life of the laundry treatment apparatus.
