Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and particularly relates to a lint filtering component and a laundry treatment device. Background Art

[0002] During the washing process of a washing machine, a large amount of lint is generated. For the current side-inlet and side-outlet lint filter, the flow velocity inside it is small, and it cannot filter lint in the mainstream area, resulting in poor lint filtering effect.

[0003] In the prior art, for example, the Chinese utility model patent with the application number CN 202321320628.0 discloses a lint filtering device and a washing machine. The lint filter includes a filter box provided with a first clamping portion, a first water inlet, and a filtering outlet; and a mounting seat provided with an opening, a second clamping portion, and a second water inlet. The filter box is slidably arranged on the mounting seat. In the present utility model, the filter box is slidably arranged on the mounting seat, and the filter box and the mounting seat are provided with matching first clamping portion and second clamping portion. When the filter box slides to close the opening, the second clamping portion is clamped with the first clamping portion to achieve sliding clamping, so that the filter box is stably installed on the mounting seat. However, the flow velocity of water inside this lint filter is small, and the filtering effect on washing water is not good.

[0004] Or, for example, the Chinese invention patent with the application number CN202210522868.2 discloses a lint filter and a washing machine, including: a front cover provided with a filtering portion thereon; a rear cover connected to the front cover, and a filtering cavity is formed between the rear cover and the front cover; and a cleaning component slidably arranged on the rear cover for cleaning the filtering impurities attached to the inner wall of the rear cover. This lint filter is arranged on the side wall of the washing tub, and there is a problem that it cannot filter lint in the mainstream area, resulting in poor lint filtering effect.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a lint filtering component, which includes a driving portion and a filtering portion. The filtering portion is installed on the washing tub and internally provided with a rotor; the driving portion is independently arranged relative to the washing tub. When the washing tub rotates, the filtering portion rotates relative to the driving portion, and the driving portion generates a driving force on the filtering portion to drive the rotor to rotate. The rotor generates a suction force to suck the washing water in the washing tub into the filtering portion for filtering, increasing the water flow velocity in the filtering portion and improving the lint collection rate.

[0007] Another purpose of the present invention is to provide a laundry treatment device adopting the above-mentioned lint filtering component.

[0008] To achieve the above purpose, the technical solution of the present invention is as follows:

[0009] A lint filtering component is applied to a laundry treatment device. The laundry treatment device includes a washing drum that rotates relative to the housing during operation. The lint filtering component includes:

[0010] A filtering part, which is installed on the washing drum and has a rotor inside;

[0011] A driving part, which is arranged independently of the washing drum;

[0012] When the laundry treatment device is in the working state, relative movement occurs between the filtering part and the driving part, and the driving part generates a non-contact force on the filtering part to drive the rotor to rotate.

[0013] In the above solution, the laundry treatment device includes a washing drum that rotates during operation. The filtering part of the lint filtering component is installed inside the washing drum, and there is a rotor inside the filtering part. The driving part is arranged independently of the washing drum. When the laundry treatment device is in the working state, the filtering part rotates relative to the driving part along with the washing drum. The driving part generates a non-contact force on the filtering part to drive the rotor inside the filtering part to rotate. The rotating rotor generates a suction force to suck the washing water in the washing drum into the filtering part for filtering, improving the lint collection rate of the lint filtering component.

[0014] Optionally, a mounting member is fixed inside the filtering part;

[0015] The rotor is a magnetic rotor, and the magnetic rotor is rotatably arranged on the mounting member;

[0016] The driving part generates a magnetic field. When the washing drum rotates, the magnetic rotor rotates on the mounting member under the action of the magnetic field force.

[0017] In the above solution, a mounting member is fixed to the filtering part, the rotor is rotatably arranged on the mounting member, and the rotor is a magnetic rotor. When the magnetic rotor makes relative movement with the driving part, the magnetic rotor will rotate under the action of the magnetic force. When the washing drum rotates, the magnetic rotor rotates under the action of the magnetic force of the driving part. The rotating magnetic rotor generates a suction force to suck the washing water in the washing drum into the filtering part for filtering. The magnetic rotor can be rotated by using the rotation of the washing drum, improving the lint filtering effect.

[0018] Optionally, the magnetic rotor is a magnetic vane. The magnetic vane is rotatably assembled on the mounting member, and the magnetic poles are arranged on both sides of the mounting member. The two magnetic poles of the magnetic vane rotate around the mounting member, and the rotation paths of the two magnetic poles of the magnetic vane are parallel to the axial direction of the washing drum.

[0019] In the above solution, the path formed by the rotation of the two magnetic poles of the magnetic vane is parallel to the axial direction of the washing drum. When the magnetic vane rotates, it generates a suction force in the axial direction, sucking the washing water in the washing drum into the filtering part and increasing the flow rate of the water in the filtering part, thereby improving the lint collection rate.

[0020] Optionally, the magnetic rotor includes an even number of magnetic vanes, and the magnetic pole setting directions of adjacent magnetic vanes are opposite;

[0021] The rotation paths of the two magnetic poles of the magnetic vane are perpendicular to the axial direction of the washing tub.

[0022] In the above solution, a plurality of magnetic vanes are provided, and the rotation paths of the two magnetic poles of the magnetic vane are perpendicular to the axial direction of the washing tub. When the magnetic vane rotates, a radial force is generated to suck the washing water in the washing tub into the filtering part, increasing the water flow speed in the filtering part and enhancing the lint filtering effect of the lint filtering component.

[0023] Optionally, the driving part is a magnetic ring formed by a plurality of magnet blocks arranged at intervals around the inner wall or the outer wall of the washing tub. The magnetic pole setting directions between adjacent magnet blocks are opposite, and the connection direction between the two magnetic poles of the magnet block is parallel to the path formed when the magnetic vane rotates.

[0024] In the above solution, the connection direction between the magnetic poles of the magnet block is parallel to the path formed when the magnetic vane rotates. When the rotation path formed by the two magnetic poles of the magnetic vane is parallel to the axial direction of the washing tub, the connection direction between the two magnetic poles of the magnet block is perpendicular to the axial direction of the washing tub; when the connection direction between the two magnetic poles of the magnetic vane is perpendicular to the axial direction of the washing tub, the connection direction between the two magnetic poles of the magnet block is parallel to the axial direction of the washing tub. Different solutions are adapted according to the use environment to ensure the lint collection rate of the lint filtering component.

[0025] Optionally, the distance between the magnetic poles of each magnet block is adapted to the distance between the adjacent magnetic poles of the magnetic vane,

[0026] and the distance between adjacent magnet blocks is adapted to the distance between the end of the magnetic vane and the installation position of the installation part.

[0027] In the above solution, the distance between the magnetic poles of the magnetic vane is adapted to the distance between the magnetic poles of each magnet block, and the distance between adjacent magnet blocks is adapted to the distance between the end of the magnetic vane and the installation position of the installation part, ensuring the continuity of the rotation of the magnetic rotor and ensuring that the washing water is sucked into the filtering part when the magnetic rotor rotates.

[0028] Optionally, the installation part is a straight rod arranged in the filtering part, and the magnetic rotor is rotatably arranged at the end or the middle of the straight rod.

[0029] In the above solution, the magnetic rotor is rotatably installed in the filtering part through the straight rod. When the magnetic rotor is installed at the end of the straight rod, the other end of the straight rod is fixed on the filtering part; when the magnetic rotor is installed in the middle of the straight rod, both ends of the straight rod are fixed on the filtering part, and the magnetic rotor can adjust its position on the straight rod according to different water levels in the washing tub to ensure the lint collection rate.

[0030] Optionally, several straight rods are arranged inside the installation part, and multiple magnetic rotors are arranged in the middle of the straight rods.

[0031] In the above solution, multiple straight rods are arranged inside the installation part, or multiple magnetic rotors are arranged on the straight rods, increasing the water flow velocity inside the filtering part, thereby improving the lint filtering effect.

[0032] Optionally, multiple installation parts are installed on the washing cylinder, and the multiple installation parts are driven by one or more driving parts.

[0033] A clothing treatment device is equipped with the lint filtering component described in the above solution.

[0034] The present invention has at least the following beneficial effects:

[0035] 1. The lint filtering component disclosed in the present invention includes a filtering part and a driving part. The filtering part is installed on the washing cylinder, and the driving part is arranged independently of the washing cylinder. A rotor is arranged inside the filtering part. When the washing cylinder rotates, the rotor rotates under the driving force of the driving part, increasing the water flow velocity inside the filtering part and sucking the washing water in the washing cylinder into the filtering part, increasing the lint collection rate and improving the user experience.

[0036] 2. In the present invention, the rotor is rotatably arranged on the mounting part through a mounting member. The rotor is a magnetic rotor, and the driving part is a magnetic ring formed by arranging multiple magnetic blocks at intervals, and the magnetic pole setting directions of adjacent magnetic blocks are opposite. When the washing cylinder rotates, the magnetic rotor rotates under the action of the magnetic force of the magnetic ring, thereby increasing the flow velocity of the water flow inside the filtering part.

[0037] 3. There are two setting methods for the magnetic rotor and the magnetic block in the present invention. One is that the rotation paths of the two magnetic poles of the magnetic rotor are parallel to the axis direction of the washing cylinder. At this time, the magnetic rotor mainly generates an axial force; the other is that the rotation paths of the two magnetic poles of the magnetic rotor are perpendicular to the axis direction of the washing cylinder. At this time, the magnetic rotor mainly generates a radial force. Different setting methods are selected according to specific practical scenarios to enhance applicability.

[0041] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Those skilled in the art can understand that the following embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0042] In the description of the present invention, unless otherwise clearly defined and limited, the terms "arrangement" and "connection" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0044] The present invention discloses a lint filtering assembly for a laundry treatment device. The laundry treatment device includes a rotary washing drum 1, which rotates relative to the housing during operation. The lint filtering assembly includes a filtering part 11 and a driving part. The filtering part 11 is installed on the washing drum 1 and has a rotor inside. The driving part is independently arranged relative to the washing drum 1. Specifically, when the laundry treatment device includes an outer drum surrounding the inner drum, the driving part can be fixed to the inner wall or outer wall of the outer drum, or fixedly installed on the housing of the laundry treatment device, ensuring that when the laundry treatment device is in a working state, the filtering part 11 of the lint filtering assembly and the driving part move relative to each other, and the driving part generates a non-contact force on the filtering, and the non-contact force drives the rotor in the filtering part 11 to rotate. The rotation of the rotor generates a suction force to suck the washing water in the washing drum 1 into the filtering part 11 for filtering, thereby improving the lint filtering efficiency of the laundry treatment device and enhancing the user experience.

[0045] Furthermore, a mounting member 12 is fixed inside the filtering part 11, and the rotor is a magnetic rotor, which is rotatably arranged on the mounting member 12. The driving part generates a magnetic field. When the laundry treatment device is in a working state, the magnetic rotor rotates relative to the magnetic field, and the magnetic rotor rotates on the mounting member 12 under the action of the magnetic field force, sucking the washing water in the washing drum 1 into the filtering for filtering, and using the rotation of the washing drum 1 during operation to improve the lint filtering effect during the operation of the laundry treatment device, thereby increasing the lint collection rate.

[0046] Furthermore, as a specific implementation manner of this embodiment, as Figure 2As shown, the mounting member 12 is a straight rod disposed within the filtering portion 11. One end or both ends of the straight rod are fixed to the filtering portion 11. The magnetic rotor is rotatably provided with magnetic vanes 13 on the straight rod. Specifically, the magnetic vanes 13 can be provided at the end or the middle of the straight rod. In the schematic diagram, the magnetic vanes 13 are provided at the end of the straight rod. The two magnetic poles of the magnetic vanes are respectively provided at both ends of the connection with the straight rod, and the vanes where the two magnetic poles are located are rotatably provided at the connection with the straight rod.

[0047] As is well known to those skilled in the art, in Figure 2 the filtering portion further includes components such as a filter net that can achieve the filtration of washing water, which are not marked in the schematic diagram.

[0048] Furthermore, when the magnetic rotor is provided in the middle of the straight rod, its position on the straight rod can be adjusted according to the water level in the washing tub 1, thereby improving the lint collection rate of the filtering portion 11.

[0049] Alternatively, when the magnetic rotor is provided in the middle of the straight rod, multiple magnetic rotors can be provided on the straight rod. When the laundry treatment device is in operation, the rotational speeds of the multiple magnetic rotors on the straight rod are different, and a suction force is generated between the magnetic rotors with different rotational speeds to suck the washing water in the washing tub 1 into the filtering portion 11 for filtration, further improving the lint collection rate of the lint filtering assembly.

[0050] Furthermore, multiple straight rods are provided within the filtering portion 11, magnetic rotors are provided on each straight rod, and a rotational speed difference is formed among the magnetic rotors on each straight rod, further increasing the suction force generated by the filtering portion 11.

[0051] Furthermore, multiple filtering portions 11 are mounted on the washing tub 1, and the multiple filtering portions 11 are driven by one or more driving portions. Specifically, when the multiple filtering portions 11 are provided at the same height of the washing tub 1, one filtering portion 11 is independently provided at a height adapted to the filtering portion 11 relative to the washing tub 1; when the multiple filtering portions 11 are provided at different heights of the washing tub 1, the multiple filtering portions 11 are independently provided at respective heights adapted to the filtering portion 11 relative to the washing tub 1.

[0052] As an embodiment of the present invention, the magnetic rotor includes a magnetic blade 13, the magnetic blade 13 has a certain thickness and radian, the magnetic blade 13 is rotatably assembled on the mounting member 12. After the magnetic blade 13 and the mounting member 12 are assembled, the two magnetic poles of the magnetic blade 13 are respectively arranged on both sides of the mounting member 12, and the shapes on both sides are centrosymmetric around the center of the mounting position, ensuring a certain suction force is generated when the blade rotates. When the magnetic blade 13 works, the two magnetic poles rotate around the mounting member 12, and the path formed when the magnetic blade 13 rotates is parallel to the axial direction of the washing tub 1. When the laundry treatment device is in the working state, the magnetic blade 13 generates a suction force in the axial direction to suck the washing water in the washing tub 1 into the filtering part 11.

[0053] It should be further noted that the rotation path of the two magnetic poles of the magnetic blade 13 refers to the cylinder formed when the magnetic blade 12 rotates around the mounting member 12. In this embodiment, the bottom surface or the top surface of the cylinder is parallel to the axial direction of the washing tub.

[0054] As Figure 1 shown, the different magnetic poles of the magnetic blocks in the figure are represented by black and white blocks respectively. When the rotation path of the magnetic poles of the magnetic blade 13 is parallel to the axial direction of the washing tub 1, the driving part is a magnetic ring formed by a plurality of magnetic blocks 2 arranged at intervals around the washing tub 1. The magnetic ring forms an annular magnetic field around the washing tub 1. The magnetic pole setting directions of adjacent magnetic blocks 2 on the magnetic ring are opposite. The path direction between the magnetic poles of each magnetic block 2 is parallel to the axis direction of the washing tub 1, and the path direction formed by the two magnetic poles of the magnetic block 2 is parallel to the plane formed when the magnetic blade 13 rotates. Specifically, when the laundry treatment device is in the working state, the mounting member 12 rotates coaxially relative to the magnetic ring. During the rotation process, when the S pole and the N pole of the magnetic blade 13 pass through the magnetic ring, they are attracted by the magnetic blocks 2 with opposite magnetic pole setting directions of the adjacent magnetic rings and rotate, thereby generating a suction force to suck the washing water in the washing tub 1 into the filtering part 11.

[0055] Furthermore, in order to ensure the smoothness of the rotation of the S pole and the N pole of the magnetic blade 13, the distance between the magnetic poles of each magnetic block 2 on the magnetic ring is adapted to the distance between the magnetic poles of the magnetic blade 13, and the distance between adjacent magnetic blocks 2 is also adapted to the distance between the magnetic poles of the magnetic blade 13. During the rotation of the washing tub 1, the magnetic blade 13 rotates one circle every time it passes through two spaced magnetic blocks 2. That is to say, the rotation speed of the magnetic blade 13 depends on the distance between the S pole and the N pole of the magnetic blade 13. The larger the distance between the two magnetic poles of the magnetic blade 13, the fewer the number of rotations of the blade when the washing tub 1 rotates one circle; the smaller the distance between the two magnetic poles of the magnetic blade 13, the more the number of rotations of the blade when the washing tub 1 rotates one circle. The distance between the magnetic poles of the magnetic blade 13 is set according to the specific situation of the laundry treatment device.

[0056] Furthermore, when the magnetic blade 13 or the magnetic block 2 is set as an electromagnet, the rotational speed of the magnetic blade 13 can be adjusted by changing the air gap of the electromagnet to adapt to different working conditions.

[0057] As another embodiment of the present invention, different from the above solution, the rotation paths of the two magnetic poles of the magnetic blade 13 are perpendicular to the axial direction of the washing tub 1, and the number of blades of the magnetic rotor is not limited to one. Multiple magnetic blades 13 can also be provided on the mounting member 12. The magnetic blade 13 has a certain thickness and curvature. When the magnetic blade 13 rotates, it generates a suction force to attract the washing water in the washing tub 1. The number of magnetic blades 13 is an even number, and the magnetic pole setting directions of adjacent magnetic blades 13 are opposite. The magnetic blades 13 are centrosymmetric about the rotation point center on the mounting member 12.

[0058] Furthermore, when the rotation path generated by the rotation of the magnetic blade 13 is parallel to the axial direction of the washing tub 1, the driving part is formed by a plurality of spaced magnetic blocks 2 surrounding the inner wall or the outer wall of the washing tub 1 to form a magnetic ring. The rotation paths of the two magnetic poles of each magnetic block 2 are perpendicular to the axis direction of the washing tub 1. Specifically, when the laundry treatment device is in a working state, the mounting member 12 rotates coaxially relative to the magnetic ring. During the rotation process, the magnetic pole of the magnetic blade 13 far from the mounting end sequentially passes through the S pole and the N pole of the magnetic block 2 and rotates, thereby generating a suction force to suck the washing water in the washing tub 1 into the filtering part 11.

[0059] Furthermore, in order to ensure the smoothness of the rotation process of the magnetic blade 13, the distance between the magnetic poles of each magnetic block 2 on the magnetic ring is adapted to the distance between adjacent magnetic blades 13, and the installation height of the magnetic block 2 is equivalent to the installation height of the magnetic blade 13. During the rotation of the washing tub 1, the magnetic blade 13 rotates one circle every time it passes through the magnetic blocks 2 with a matching number. That is to say, when there are four blades on the mounting member 12, the mounting member 12 rotates one circle every time it passes through four spaced magnetic blocks 2. In this embodiment, the rotation speed of the magnetic blade 13 is related to the number of magnetic blades 13 provided on the mounting member 12. The number of magnetic blades 13 on the mounting member 12 is set according to the specific situation of the laundry treatment device, enhancing the applicability of the present invention.

[0060] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above to obtain equivalent embodiments of equivalent changes. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
