Description

Technical Field

[0001] This utility model relates to the technical field of washing machines, and specifically to a washing machine. Background Technology

[0002] Existing washing machines include front-loading washing machines and top-loading washing machines. Both types of washing machines rely on an internal motor to rotate, thereby driving the internal structure for cleaning. Front-loading washing machines use a motor to drive the drum to tumble the clothes, causing them to continuously roll inside the drum to achieve the effect of patting and rubbing. Top-loading washing machines use a motor to drive the impeller to rotate at high speed, agitating the internal water flow to move the clothes, causing them to tumble up and down inside to achieve the purpose of cleaning.

[0003] Both types of washing machines mentioned above rely on traditional electric motors for operation, which are typically installed below the washing tub (especially in top-loading washing machines). Water can easily leak from the tub, drain pipe, or inner drum, seeping into the motor area. Once water gets in, it can cause short circuits, insulation aging, or even burnout of the motor, rendering the washing machine unusable.

[0004] Existing technologies improve waterproof ratings and motor sealing to prevent motor leaks. However, during long-term use, the washing machine comes into contact with water during the washing process and dries slowly afterward. This can cause the sealing structure to age or break, leading to sealing problems. Consequently, internal circuits may short-circuit or burn out due to water leakage, ultimately rendering the washing machine unusable. Utility Model Content

[0060] This utility model proposes a washing machine 100, comprising:

[0061] Cylinder 110;

[0062] The base 120 has a sealing groove 120a inside, which is fastened to the cylinder 110 to form a cleaning groove 120b;

[0063] The drive assembly 130 is disposed within the sealing groove 120a;

[0064] Cleaning component 140 is detachably connected to the base 120 and rotatably connected to the base 120. The cleaning component 140 is located inside the cleaning tank 120b.

[0065] A rotating assembly 150 is mounted on the cleaning component 140, and the rotating assembly 150 is coupled to the driving assembly 130.

[0066] The drive component 130 generates a changing magnetic field to drive the rotating component 150 to rotate, thereby causing the cleaning component 140 to rotate within the cleaning tank 120b.

[0067] Please refer to Figures 1-7 In this embodiment, a changing magnetic field is generated by the drive component 130 set in the sealing groove 120a of the base 120, which drives the rotating component 150 installed on the cleaning component 140 to rotate, thereby causing the cleaning component 140 to rotate in the washing tank 120b, so as to realize the washing or spin-drying function of clothes.

[0068] The drum 110 and the base 120 are interlocked to form the washing tub 120b of the washing machine 100. The base 120 has a sealed groove 120a inside to isolate the internal electrical components from the water environment. The drive assembly 130 is fixedly disposed within this sealed groove 120a, in a dry and sealed space, avoiding the risk of contact with the washing liquid.

[0069] The cleaning component 140 is detachably mounted on and rotatably connected to the base 120, and is located within the cleaning tank 120b. It is a component used for cleaning. A rotating assembly 150 is mounted on the cleaning component 140. The rotating assembly 150 and the driving assembly 130 below are spatially opposite each other, forming a magnetic coupling structure.

[0070] When the washing machine 100 is running, the drive assembly 130 generates a rotating magnetic field under the power supply. This magnetic field interacts with the magnetic element in the rotating assembly 150 on the cleaning component 140 through the base 120 structure, thereby causing the rotating assembly 150 to generate a rotational torque. Since the rotating assembly 150 is linked with the cleaning component 140, the cleaning component 140 rotates within the washing tub 120b, thereby causing the water to tumble and achieving the washing or spin-drying function.

[0071] The drive assembly 130 is housed within the sealed groove 120a, completely isolated from the washing water, and transmits power via a magnetic field, eliminating the need for a direct connection between the motor and the cleaning component 140. This avoids the problem of short circuits or damage to the motor due to water ingress, as is common in traditional designs, significantly improving the waterproof capability and electrical safety of the washing machine 100.

[0072] Power transmission is achieved through magnetic coupling, eliminating the need for traditional drive shafts, seals, and other mechanical structures. This reduces the likelihood of mechanical wear and seal aging, improving the overall stability and service life of the machine.

[0073] The cleaning component 140 features a detachable structure, facilitating daily maintenance or function switching (such as replacing different types of impellers or spin-dry tubs), thus enhancing the applicability and maintenance convenience of the washing machine 100.

[0074] The magnetic field generated by the drive component 130 can achieve multi-frequency and multi-mode control, with adjustable speed and variable direction, which helps to realize various washing programs (such as gentle wash, strong wash, spin dry, etc.), improving washing effect and energy efficiency ratio.

[0075] It should be noted that the cylinder 110 is generally a cylindrical shape with one end open and an internal cavity structure; the base 120 is generally a hollow can shape with an internal sealing groove 120a; the cylinder 110 and the base 120 are fastened together to form a cleaning groove 120b.

[0076] The driving component 130 is a magnetic induction coil.

[0077] Preferably, the base 120 is provided with a positioning post 121;

[0078] The cleaning component 140 has a positioning hole 140a and a mounting groove 140b communicating with the positioning hole 140a on one side. The rotating component 150 is installed in the mounting groove 140b. One end of the positioning post 121 is received in the positioning hole 140a and is rotatably connected to the cleaning component 140.

[0079] Please refer to Figures 1-7 In this embodiment, the base 120 is provided with an upwardly extending positioning post 121, which provides a position for the cleaning component 140 to be installed and serves as its rotation axis during subsequent operation.

[0080] The cleaning component 140 has a positioning hole 140a on one side, which matches the shape of the positioning post 121 on the base 120 for mounting connection. In addition, the cleaning component 140 also has a mounting groove 140b communicating with the positioning hole 140a for mounting and fixing the rotating assembly 150.

[0081] During installation, the user simply aligns the cleaning component 140 with the positioning post 121 on the base 120 and inserts it into the positioning hole 140a for quick positioning. The rotating component 150 is pre-installed in the mounting slot 140b of the cleaning component 140, so that it is spatially aligned with the drive component 130 inside the base 120, forming a magnetic coupling structure.

[0082] The positioning post 121 and the cleaning component 140 are rotatably connected. During actual operation, the cleaning component 140 can rotate around the positioning post 121, while the positioning post 121 remains stationary. The rotating component 150 on the cleaning component 140 is coupled to the driving component 130 through magnetic force, driving the cleaning component 140 to rotate and realize the washing or dehydration function.

[0083] The structural fit between the positioning post 121 and the positioning hole 140a enables the cleaning component 140 to be installed quickly and accurately in the predetermined position, ensuring that the rotating assembly 150 and the driving assembly 130 are correctly aligned in the axial and radial directions, thereby improving the driving efficiency and response stability of the magnetic coupling.

[0084] Because of the positioning and interlocking structure, the assembly of the cleaning component 140 is simple and intuitive. It can be installed or disassembled without the use of complicated tools, making it easy to maintain, replace or clean.

[0085] The positioning column 121 not only serves a positioning function, but also acts as the rotational center axis of the cleaning component 140, supporting its rotation around itself. This reduces shaking, eccentricity, or friction during operation, significantly improving the stability and service life of the equipment.

[0086] By centrally installing the rotating assembly 150 within the mounting slot 140b of the cleaning component 140 and magnetically coupling it with the bottom drive assembly 130, a layered transmission structure is formed, which helps to achieve sealed isolation of electrical components and improves the overall waterproof performance and structural integration of the machine.

[0087] It should be noted that the positioning post 121 is roughly cylindrical and is fixed to the base 120 with screws or the like. A sealing structure such as a sealing ring is provided between the positioning post 121 and the base 120.

[0088] The positioning hole 140a is roughly a round hole formed by the inward recess of the cleaning component 140 near the drive assembly 130. The cleaning component 140 is fixed on the positioning post 121 by a structure such as a snap-fit, and a rotational connection is formed. It can be a limit snap-fit.

[0089] Preferably, the rotating assembly 150 includes:

[0090] The first magnetic yoke 151 is installed in the mounting groove 140b, and a fixing groove 151a is provided on the side of the first magnetic yoke 151 near the drive assembly 130.

[0091] The magnetic component 152 is installed in the fixing groove 151a and coupled to the driving assembly 130.

[0092] Please refer to Figures 1-7 In this embodiment, the rotating assembly 150 is installed in the mounting groove 140b of the cleaning component 140, which includes a first magnetic yoke 151. The first magnetic yoke 151 is disposed near the drive assembly 130 in the base 120 of the washing machine 100, and its structure has a fixing groove 151a on the side facing the drive assembly 130 for accommodating magnetic elements.

[0093] A magnetic component 152 (such as a permanent magnet) is securely mounted in the fixing groove 151a of the first magnetic yoke 151, forming an independent magnetic response unit. The magnetic component 152 is spatially aligned with the drive assembly 130 within the sealing groove 120a of the base 120.

[0094] When the washing machine 100 is in operation, the drive assembly 130 located in the sealing groove 120a generates a rotating magnetic field after being energized. This magnetic field passes through the base 120 structure and is magnetically coupled with the magnetic component 152. The changing magnetic field of the drive assembly 130 causes the magnetic component 152 to rotate accordingly. Since the magnetic component 152 is fixed on the first magnetic yoke 151, the first magnetic yoke 151 rotates accordingly, thereby driving the entire rotating assembly 150 to move. As part of the cleaning component 140, the rotating assembly 150 rotates after being driven by the magnetic force, thereby driving the cleaning component 140 to rotate within the washing tub 120b, realizing the functions of tumbling, washing, or spin-drying clothes.

[0095] The first magnetic yoke 151 provides a stable mounting position and magnetic flux path for the magnetic component 152, ensuring that the magnetic field generated by the magnetic component 152 and the drive assembly 130 does not penetrate the first magnetic yoke 151 to the outside. Furthermore, part of the magnetic field generated by the drive assembly 130 acts on the magnetic component 152, and the other part, after passing through the first magnetic yoke 151, is reflected back onto the magnetic component 152, resulting in a better driving effect for the magnetic component 152, a faster rotation speed for the magnetic component 152, and a better cleaning effect for the cleaning component 140.

[0096] The magnetic component 152 is embedded in the fixing groove 151a, close to the drive component 130, which effectively improves the magnetic coupling strength between it and the drive component 130, and improves the overall magnetic field transmission efficiency, making the drive response more sensitive and the rotation more stable.

[0097] The first magnetic yoke 151 and the magnetic component 152 are integrated and installed in the mounting slot 140b of the cleaning component 140, without occupying extra space, making the structure more compact.

[0098] There is no direct contact between the magnetic component 152 and the drive assembly 130. The torque is transmitted only through the magnetic field, which avoids the problems of wear, water leakage and seal aging caused by traditional mechanical connections. This helps to achieve a fully enclosed and waterproof design for electric drive components.

[0099] Since there is no mechanical meshing or friction, magnetic coupling transmission has less vibration, lower noise, and smoother operation, which can effectively improve the user experience.

[0100] It should be noted that the first magnetic yoke 151 is made of magnetic shielding material and is roughly circular in shape. The magnetic component 152 can be a bar magnet, a ring magnet, or an integral or separate magnet. It can be a two-pole or multi-pole magnet, including but not limited to the above-mentioned magnets and their arrangement. In this embodiment, it is a ring magnet with multiple poles. The mounting groove 140b is a circular groove and is formed on the side of the cleaning component 140 near the drive assembly 130; the fixing groove 151a is a circular groove and is formed on the side of the first magnetic yoke 151 near the drive assembly 130.

[0101] Preferably, the drive component 130 includes:

[0102] A drive motor 131 is installed in the sealing groove 120a;

[0103] A drive magnet 132 is installed at the output end of the drive motor 131 and coupled to the rotating assembly 150.

[0104] Please refer to Figures 1-9The drive motor 131 rotates, which drives the drive magnet 132 to rotate. Since the drive magnet 132 is magnetically coupled with the magnetic component 152, the drive magnet 132 rotates while driving the magnetic component 152 rotates synchronously, so as to drive the cleaning component 140 to rotate inside the drum 110 to clean the clothes.

[0105] It should be noted that the drive motor 131 is a motor or electric motor, and the drive magnet 132 is a magnetic magnet, which can be a single or multiple magnets, arranged at equal angles or in a ring.

[0106] Preferably, there are multiple drive components 130, and the multiple drive components 130 are arranged at equal angles with the axis of the positioning post 121 as the axis.

[0107] Please refer to Figures 1-7 In this embodiment, a plurality of drive components 130 (e.g., electromagnetic coils) are provided in the sealing groove 120a of the base 120 of the washing machine 100. These drive components 130 are arranged at equal angular intervals along the circumferential direction with the axis of the positioning post 121 at the center of the base 120 as the center axis, forming a ring layout.

[0108] The cleaning component 140 is mounted on the positioning post 121 and is rotatable about the axis. The lower part of the cleaning component 140 is provided with a rotating assembly 150, which includes a magnetic component 152 (such as a permanent magnet) located in the area directly above the plurality of drive components 130 in the base 120.

[0109] When the washing machine 100 is running, multiple drive components 130 in the sealing groove 120a of the base 120 are synchronously or alternately energized, forming a changing magnetic field at their respective positions. As the cleaning component 140 rotates, the magnetic component 152 will continuously pass over the multiple drive components 130, and generate a periodic coupling effect with the magnetic field of each drive component 130, so that the magnetic component 152 is always within the coverage of the annular magnetic field, thereby achieving continuous and stable magnetic drive, driving the entire cleaning component 140 to rotate to complete the washing or spin-drying action.

[0110] Multiple drive components 130 are arranged at equal angles around the rotation axis of the cleaning component 140, forming a complete annular magnetic drive area in space. No matter where the cleaning component 140 rotates, the magnetic component 152 can maintain effective coupling with a certain drive component 130, thereby ensuring the continuity and balance of the driving force.

[0111] Since the driving force is not provided by a single drive component 130, but by multiple drive components 130 distributed and cooperating to output magnetic force, the torque can be distributed more evenly during rotation, avoiding rotational fluctuations and effectively improving rotational stability and torque output capability during startup / operation.

[0112] Even if one of the drive components 130 fails, the remaining drive components 130 can still form magnetic coupling with the magnetic component 152, which has good fault tolerance, thereby improving the stability and lifespan of the entire washing machine 100 system in long-term use.

[0113] Multiple drive components 130 can be controlled independently or in groups through circuit control, thereby realizing multiple magnetic field switching modes, enabling the washing machine 100 to support different speeds, directions and energy-saving modes, and possessing a good foundation for intelligent control.

[0114] Preferably, the magnetic poles of the magnetic component 152 are denoted as a, and the number of the driving components 130 is denoted as b, satisfying the following relationship:

[0115] a = b.

[0116] Please refer to Figures 1-7 In this embodiment, in order to achieve efficient non-contact magnetic coupling drive, the number of magnetic poles (a) on the magnetic component 152 and the number of drive components 130 in the base 120 (b) are set to be equal, that is, a = b, so as to achieve the best magnetic coupling effect.

[0117] The magnetic component 152 is installed in the rotating assembly 150 on the cleaning component 140 and has multiple magnetic poles, such as alternating N and S poles. The drive assembly 130 (such as an electromagnetic coil) is installed in the sealing groove 120a of the base 120 of the washing machine 100, and its number is the same as the number of magnetic poles. They are arranged at equal angles around the rotation axis of the cleaning component 140.

[0118] The cleaning component 140 rotates around the positioning post 121, and the magnetic component 152 moves accordingly. Each magnetic pole on it passes above a corresponding drive component 130 in sequence during the rotation. The drive component 130 is controlled to generate a rotating magnetic field, which forms a dynamic magnetic coupling with the magnetic pole directly above it, providing rotational driving force.

[0119] Since the number of magnetic poles is the same as that of the drive components 130, at any given time during the rotation of the cleaning component 140, there is a magnetic pole facing a drive component 130, forming a continuous and uniform magnetic field, which enables the cleaning component 140 to rotate smoothly, thereby driving the water flow to agitate or completing the spin-drying action.

[0120] Each magnetic pole is always driven by a corresponding drive component 130 during rotation, eliminating the window period of magnetic force action, ensuring continuous magnetic flux and stable torque, and effectively improving magnetic field utilization and rotation drive efficiency.

[0121] Preferably, the magnetic poles of the magnetic component 152 are denoted as a, and the number of the driving components 130 is denoted as b, satisfying the following relationship:

[0122] a>b or a<b.

[0123] Please refer to Figures 1-7 In this embodiment, when a > b (the number of magnetic poles is greater than the number of drive components 130), during the rotation of the cleaning component 140, multiple magnetic poles will pass over one drive component 130 in turn. The magnetic field generated by the drive component 130 can act on the continuously passing magnetic poles on the time axis to achieve multi-frequency response, that is, the magnetic coupling change frequency within each revolution is higher, which can be used to improve rotation accuracy and response speed. It is suitable for working modes that require rapid switching of magnetic field direction or high-frequency drive (such as variable speed, pulse wash, slow gentle wash, etc.).

[0124] When a < b (the number of magnetic poles is less than the number of drive components 130), during the rotation of the cleaning component 140, multiple adjacent drive components 130 act on the same magnetic pole. Due to the overlapping of magnetic fields, a single magnetic pole can obtain a stronger driving force, thereby improving the overall driving torque. This is suitable for working modes with high power output requirements, such as high-load washing or high-speed spin drying.

[0125] When a > b, the magnetic field switching frequency is higher, which is conducive to achieving fine actions such as high-frequency vibration and low-speed gentle washing. When a < b, each magnetic pole acts on multiple drive components 130, which is conducive to improving the magnetic strength and starting torque, realizing multiple drive modes and multiple washing programs, such as gentle washing, strong washing, spin drying, energy-saving washing, etc.

[0126] Preferably, the washing machine 100 further includes:

[0127] A magnetic guide 160 is disposed on the side of the drive assembly 130 away from the rotation assembly 150;

[0128] Circuit board 161 is disposed on the magnetic guide 160;

[0129] A touch screen 162 is mounted on the base 120;

[0130] The driving power supply 163 is disposed in the sealing groove 120a, and the circuit board 161 is electrically connected to the driving assembly 130, the driving power supply 163 and the touch display screen 162 respectively.

[0131] Please refer to Figures 1-7 In this embodiment, the magnetic guide 160 is installed on the side of the drive assembly 130 away from the rotating assembly 150, that is, the side opposite to the magnetic field lines. The magnetic guide 160 guides, focuses and shields the magnetic field generated by the drive assembly 130, so that the magnetic force acts more concentratedly on the opposite magnetic component 152, thereby improving the magnetic coupling efficiency and magnetic field utilization.

[0132] The circuit board 161 is mounted on the magnetic guide 160 and located inside the sealing groove 120a. It is electrically connected to multiple drive components 130, a power supply, and a display interface. Its functions include controlling the power on and off of the drive components 130, adjusting parameters such as current frequency and phase, and realizing dynamic control of the magnetic field and management of the washing program.

[0133] The drive power supply 163 is located in the sealed groove 120a, providing stable operating voltage and current for the drive assembly 130 and the circuit board 161. The drive power supply 163 is connected to the circuit board 161 and is controlled by it to turn on or adjust the output.

[0134] The touch screen 162 is mounted on the base 120 for users to input operation commands (such as selecting washing programs, time, spin speed, etc.). The touch screen 162 is electrically connected to the circuit board 161. The input commands are processed by the circuit board 161 and fed back to the drive system, thereby realizing a closed loop of human-machine interaction control.

[0135] After the user sets parameters via the touch screen, the circuit board 161 controls the drive component 130 to be powered on or frequency-controlled according to the settings. The drive component 130 forms a magnetic coupling with the magnetic component 152 at the bottom of the cleaning component 140 through the changing magnetic field, thereby driving the cleaning component 140 to rotate and realize the washing or spin-drying function.

[0136] By setting up the magnetic guide 160, the magnetic force generated by the drive assembly 130 can be concentrated on the target magnetic component 152, effectively reducing magnetic flux leakage, improving the directionality and utilization rate of the magnetic field strength, thereby improving the overall driving force and energy efficiency ratio.

[0137] The circuit board 161, the drive power supply 163 and the drive assembly 130 are uniformly arranged in the sealed groove 120a to form a closed control module. The electrical components are not directly exposed to the humid environment, which enhances the system's waterproof and dustproof performance and extends its service life.

[0138] The magnetic guide 160 is roughly circular and made of a magnetically cohesive material, so that the magnetic field of the drive assembly 130 can act on the magnetic component 152 under the cohesive effect of the magnetic guide 160, such as silicon steel sheet, iron and other materials.

[0139] The circuit board 161 is roughly a PCB board, the touch screen 162 can be a capacitive touch screen or a resistive touch screen, and the driving power supply 163 is a battery.

[0140] Preferably, the cleaning component 140 is an impeller, and the side of the impeller away from the drive assembly 130 protrudes outward to form a plurality of impeller portions 141. The plurality of impeller portions 141 are arranged at equal angles. The side of the impeller away from the impeller portion 141 has a planar side (not shown in the figure), and the positioning hole is opened on the planar side.

[0141] Please refer to Figures 1-7 In this embodiment, the cleaning component 140 adopts a pulsator structure, is installed on the base 120 of the washing machine 100, and can rotate around the positioning post 121. The pulsator interacts with the drive component 130 in the base 120 through a magnetic coupling structure to rotate. The upper surface of the pulsator, that is, the side away from the drive component 130, faces the inside of the washing tub and is used to directly contact water and clothes. Multiple pulsator portions 141 are provided protruding outward on this surface. These pulsator portions 141 are arranged at equal angles relative to the center of the pulsator (such as in a circular array) to ensure uniform water flow disturbance during rotation.

[0142] When the washing machine 100 is running, the drive assembly 130 drives the impeller to rotate through magnetic coupling. The impeller part 141 rotates with the impeller, strongly agitating the surrounding water flow and generating complex water flow movements such as rising, sinking, and vortex. This causes the clothes to tumble and rub in the water, thereby achieving the washing effect.

[0143] The impeller section 141 amplifies the water flow disturbance, allowing clothes to tumble more thoroughly and the water flow to penetrate more effectively.

[0144] The 141 equidistant distribution of the impeller section ensures symmetrical force and torque balance when the impeller rotates, reducing vibration and noise caused by uneven load during operation, and improving the smoothness of the washing machine's operation and user comfort.

[0145] The spiral turbulence and equal-angle layout of the impeller section 141 cause the water flow to circulate in three dimensions, effectively preventing clothes from tangling or piling up and improving the overall washing uniformity.

[0146] When cleaning is required, the cleaning component 140 can be easily removed from the cylinder 110 with minimal force. Furthermore, the impeller features a flattened bottom design (flat side), reducing hard-to-reach areas for dirt residue.

[0147] In this embodiment, the cleaning component 140 is generally a frustum-shaped disc with a triangular arc-shaped impeller portion 141 on one side.

[0148] Preferably, the cleaning component 140 is a spin-drying drum, the spin-drying drum has a spin-drying cavity 140c inside, and the peripheral wall of the spin-drying drum has a connecting groove 140d, which connects the spin-drying cavity 140c to the outside.

[0149] Please refer to Figures 1-7 In this embodiment, the cleaning component 140 is a spin-drying tub, which is installed on the base 120 of the washing machine 100. It has a spin-drying chamber 140c inside to hold clothes to be spun dry. The spin-drying tub is magnetically coupled to the drive component 130 in the base 120 through the rotating component 150, and can rotate around the central axis.

[0150] Multiple connecting grooves 140d are made on the periphery of the spin-drying tank. These connecting grooves 140d are used to discharge the water spun out of the spin-drying chamber 140c to the external space. These grooves are all connected to the spin-drying chamber 140c to ensure that the water can be discharged smoothly under the action of centrifugal force.

[0151] After the washing machine 100 enters the spin-drying program, the circuit control drive component 130 generates a rotating magnetic field. This magnetic field forms a magnetic coupling with the magnetic component 152 in the rotating component 150 below the spin-drying tub, driving the spin-drying tub to rotate at high speed. The residual water in the clothes is thrown out under the action of centrifugal force during high-speed rotation and discharged to the outside of the washing machine 100 or the water collection area through the connecting channel 140d, thus completing the dehydration operation.

[0152] The spin-dry drum can rotate at high speed, and under the action of centrifugal force, it can quickly remove the water from the clothes. The setting of the connecting groove 140d allows water to flow out quickly from the spin-drying chamber 140c, avoiding water accumulation and back seepage, and improving the dehydration efficiency.

[0153] The 140d peripheral wall connecting channel provides multiple drainage paths, improving the drainage rate. The decentralized connecting channel 140d can discharge water more evenly, reduce water flow obstruction, and optimize drainage smoothness.

[0154] The rotation of the spin-dry drum is driven by a magnetic coupling structure, which effectively improves the overall waterproof capability and electrical safety of the machine.

[0155] The spin dryer is roughly cylindrical, and the connecting groove 140d is a through groove.

[0156] Preferably, there is a gap between the cleaning component 140 and the inner wall of the cleaning tank 120b.

[0157] Please refer to Figures 1-7 In this embodiment, the cleaning component 140 rotates under the action of the magnetic field generated by the drive component 130. Due to the gap, the cleaning component 140 will not interfere with, rub against or collide with the inner wall of the cleaning tank 120b when it rotates, thus ensuring the smoothness of the rotation.

[0158] The spacing provides the necessary space for water flow, clothes to tumble, and water to be drained, while avoiding contact wear or structural jamming caused by installation errors or long-term operation.

[0159] By setting the spacing, the cleaning component 140 can be allowed to move freely at high speed, avoiding mechanical interference and noise generation.

[0160] The spacing provides a buffer space for the movement of water and clothes, which helps to create stronger water flow disturbance and tumbling trajectory. In spin-dry mode, water can be quickly thrown out through the spacing to the wall of the washing tank 120b and discharged smoothly, improving the dehydration efficiency.

[0161] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
