Detailed Implementation
[0082] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0083] Example 1 This embodiment proposes a device for supplying power inside the drum of a drum washing machine, such as... Figures 1 to 7 As shown, it includes: a pogopin circuit board 2, a locking nut 3, a conductive ring 4, a fixing block 5, a tripod 6, a support frame 8, and a DD motor 9, etc.
[0084] The telescopic electromagnet mainly consists of an electromagnet 101, a telescopic rod 104, a spring 103, and a cylindrical protrusion 102. A cylindrical protrusion 102 is fixed at the front end of the telescopic rod, and a spring is inserted at the rear end. The diameter of the cylindrical protrusion at the rear end is larger than the through hole of the electromagnet so that it can be locked to ensure that the telescopic rod pops out and maintains the set stroke distance. There is a through hole in the center of the electromagnet. The telescopic rod is inserted into the through hole of the spring and then the cylindrical protrusion 102 is fixed.
[0085] The working process of the telescopic electromagnet 1 is as follows: Power off: When no power is supplied, the telescopic electromagnet is in a non-working state, and the telescopic rod is not extended and is retracted inside the electromagnet; Power on: When the main control board is powered, the telescopic electromagnet is in working condition. The telescopic rod is subjected to the magnetic force of the electromagnet, and the magnetic force is greater than the spring force. The telescopic rod extends and maintains the set travel distance.
[0086] Specifically, the cylindrical protrusion 102 is fixedly connected to the pogopin circuit board 2. The pogopin circuit board 2 moves synchronously with the telescopic rod on the telescopic electromagnet. Both the telescopic electromagnet 1 and the pogopin circuit board 2 are electrically connected to the main control board of the washing machine. The telescopic electromagnet 1 is fixed on the support frame 8. The main control board supplies power, and when the telescopic electromagnet is energized and moves, several pogopins on the pogopin circuit board 2 move and contact the conductive ring. In this embodiment, three pogopins are used as an example. When the telescopic electromagnet is de-energized and does not move, the three pogopins on the pogopin circuit board 2 do not contact the conductive ring. Figure 5 .
[0087] The conductive ring 4 is mainly composed of insulating plastic 10, conductive wire 11, and conductive metal sheet 12, such as... Figure 6 and Figure 7 As shown, the conductive metal sheet 12 consists of three annular conductive metal sheets, and the conductive wire 11 consists of three conductive wires. The three conductive wires of the conductive wire 11 are respectively connected to the three annular conductive metal sheets in the conductive metal sheet 12. The three annular conductive metal sheets in the conductive metal sheet 12 are embedded in an insulating body, and the insulating body contains four insulating plastics 10 that separate the three annular conductive metal sheets in the conductive metal sheet 12. The conductive ring 4 has a through hole in the middle, and the conductive wire 11 bends from one side and passes through the through hole to the inner cylinder.
[0088] During installation of the device for powering the inside of the drum of the washing machine in this embodiment, the DD motor rotor 7 is fitted onto the tripod 6. The internal thread on the fixing block 5 (the fixing block has an internal thread) is connected and tightened to the external thread on the head of the tripod 6, pressing the DD motor 9. The DD motor is located on the outside of the outer drum and has a separate wire connected to the inner drum. The DD motor is used to drive the inner drum to rotate. The conductive ring 4 is fitted onto the fixing block 5, and the locking nut 3 is matched and tightened to the external thread at the end of the fixing block 5. The spacing between the three pogopins on the pogopin circuit board 2 is the same as the spacing between the three independent annular metal conductive plates on the conductive metal sheet 12, and each pogopin is located in the center of the corresponding annular metal conductive plate. After the conductive wire 11 is threaded through the center hole of the tripod, it is potted with liquid silicone. After the silicone cures, the center hole area of the tripod is completely sealed.
[0089] The working principle of the device for supplying power to the inside of the drum of the washing machine in this embodiment is as follows: When the washing machine is in the washing and rinsing / spinning programs, it is not necessary to supply power to the components inside the drum (i.e., functional components such as clamping devices, sterilization and drying devices, position sensors, temperature or humidity sensors, etc.). The main control board does not supply power to the telescopic electromagnet 1, so the telescopic electromagnet 1 does not work and the telescopic rod is in the unextended state. Since the telescopic electromagnet 1 is fixedly connected to the cylindrical protrusion 102 at the front end of the telescopic rod, the pogopin circuit board 2 does not extend out along with the telescopic rod and is away from the conductive ring 4. The pogopin does not contact the conductive ring 4, and the conductive circuit is in the disconnected state. Therefore, the components inside the drum are not powered.
[0090] When the washing machine is in the drying and sterilization programs, it needs to supply power to the components inside the drum. The main control board supplies power to the telescopic electromagnet 1, which starts working. The telescopic rod 104 pops out to the set stroke, and the pogopin pops out to the designated position. (Because the head of the pogopin has a built-in spring, it has compression conduction characteristics. As it wears over time, the unworn part will be springed out by the elastic force to maintain good conduction.) The contact end of the pogopin head contacts the annular metal conductive piece on the conductive ring 4 and conducts power. Since the annular metal conductive piece is independently connected to the conductive wire 11, the external circuit and the internal circuit of the drum are connected through the conductive wire 11 to achieve the purpose of power supply. The components inside the drum are powered on and execute the drying and sterilization programs.
[0091] This invention utilizes a pogopin circuit board, which offers numerous advantages. Pogopin connectors are small, saving space; their contacts are more precise, and their positive force is lower than that of ordinary metal springs for the same compression stroke, resulting in higher reliability. Furthermore, pogopin products have a long lifespan, at least 10,000 cycles, and typically reach 100,000 cycles. The built-in spring in the pogopin pushes the worn end back to its original position when the head wears down. The impedance is consistently stable, typically controlled within 30 milliohms, and even after lifespan testing, it remains below 50 milliohms. It is an ideal connector, resistant to high current and corrosion, making it suitable for use in in-drum power supply devices to significantly extend the washing machine's lifespan and improve its overall performance.
[0092] Example 2 This embodiment proposes a washing machine, which includes an inner drum, an outer drum, and a main control board. The inner drum contains multiple functional components, and the power supply for the functional components is provided by the device described above for powering the inside of the drum of the drum washing machine.
[0093] Preferably, the drive motor for rotating the inner cylinder is a DD motor, which is located outside the outer cylinder and has a separate wire connected to the inner cylinder. The DD motor is used to drive the inner cylinder to rotate.
[0094] This invention employs a contact-disconnection conductivity method to power the various functional components inside the drum. The power is switched on at low drum speeds and off at high speeds. Specifically, the DD motor provides real-time feedback of the current speed to the main control board. During any stage of the washing machine program before the drying cycle (washing, spin-drying, etc.), the drum speed is generally high because it is driven by the DD motor, which also operates at a high speed. During these stages, the main control board continuously disconnects the power supply to the telescopic electromagnet, preventing the pogo pin from contacting the conductive ring and avoiding wear on the conductive ring. When the washing program transitions to the drying cycle, the DD motor reduces its speed. When the internal electrical components need to operate, the main control board switches on the power supply to the telescopic electromagnet, allowing the pogo pin to contact the conductive ring and conduct electricity.
[0095] Example 3 This invention provides a device for supplying power inside the drum of a drum washing machine, combined with... Figures 9-15 As shown, it includes: Inner tube 310, used to hold clothes; The outer barrel 320 is installed on the outside of the inner barrel 310; Tripod 330 is fixedly connected to the bottom of the inner cylinder 310 to transmit rotational driving force to the inner cylinder 310; and the end of the tripod 330 extends axially along the inner cylinder 310 and passes through the outer cylinder 320 to form a pivot 331. A conductive ring 340 is fixed to the end of the rotating shaft 331 and is electrically connected to the internal functional components of the washing machine 300 tub. The bearing 350 has its inner ring fitted onto the outer wall of the conductive ring 340 and fixed thereon, so as to realize the synchronous rotation of the conductive ring 340 and the inner ring of the bearing 350. At least one circuit board assembly 360 is electrically connected to the main control board of the washing machine 300 and mounted on the outer ring of the bearing 350, and an electrical connection terminal 363 is formed on the circuit board assembly 360 for connection with the conductive ring 340. During the rotation of the conductive ring 340 relative to the circuit board assembly 360, the electrical connection terminal 363 is configured to always contact the conductive ring 340, thereby providing power to the functional components inside the washing machine 300 tub.
[0096] Specifically, when the washing machine 300 is running, the tripod 330 drives the inner drum 310 to rotate under the drive motor. The conductive ring 340 fixed at the end of the rotating shaft 331 rotates together with the tripod 330 and the inner drum 310. The circuit board assembly 360 fixed on the outer ring of the bearing 350 of the rotating shaft 331 remains stationary relative to the outer drum 320. When the conductive ring 340 rotates, the electrical connection end 363 slides and contacts the conductive ring 340 to maintain the conductive state.
[0097] This embodiment enables power supply to the functional components inside the inner drum 310 while the inner drum 310 is rotating through the conductive ring 340 and the circuit board assembly 360. In this way, the cooperation between the rotating inner drum 310 and the functional components can expand the functions of the washing machine 300, optimize the overall functions of the washing machine 300, meet different user needs, and improve the user experience. Furthermore, this arrangement effectively avoids the wires from getting tangled during rotation. It has a simple structure, stable operation, and high reliability.
[0098] In one embodiment, the surface of the conductive ring 340 that contacts the electrical connection terminal 363 is provided with a coating.
[0099] Specifically, the conductive ring 340 is made of metal and is electroplated. Inert materials such as gold plating, titanium plating, and chromium plating can be used to give the surface of the conductive ring 340 the hardness and thickness required for its lifespan, so as to achieve its wear resistance, high temperature resistance, and anti-aging properties, thereby extending the service life of the conductive ring 340.
[0100] In this embodiment, the surface of the conductive ring 340 is provided with a hardened chromium plating layer.
[0101] Specifically, chrome plating can increase the hardness and wear resistance of metal surfaces, improve the durability and wear resistance of metal parts. Therefore, by using chrome plating, the wear resistance of the conductive ring 340 is increased while the friction force of the electrical connection end 363 sliding on the conductive ring 340 is reduced. Furthermore, chrome plating can improve the conductivity of metal surfaces. Therefore, this embodiment can improve the wear resistance of the conductive ring 340 while ensuring the conductivity of the conductive ring 340, thus optimizing the overall performance of the conductive ring 340.
[0102] In one embodiment, combined with Figure 13 , Figure 14 and Figure 15 As shown, the conductive ring 340 has multiple metal conductive regions 341 corresponding to the electrical connection terminal 363, and multiple conductive lines 343 corresponding to the metal conductive regions 341; wherein, An insulating plate 342 is provided between adjacent conductive metal regions 341; One end of the conductive wire 343 is electrically connected to the metal conductive area 341, and the other end passes through the internal wiring channel of the tripod 330 to enter the outside of the inner cylinder 310 and connect to the power supply terminal of the functional component.
[0103] In this embodiment, the conductive ring 340 corresponds one-to-one with the electrical connection terminal 363, the metal conductive area 341 is annular, and the insulating plate 342 is also annular in structure, which is embedded in the surface of the conductive ring 340 to separate two adjacent metal conductive areas 341.
[0104] In one embodiment, such as Figure 13 As shown, the tripod 330 has a hollow section inside to form the wiring channel.
[0105] Furthermore, the tripod 330 includes a frame 332 and a pivot 331, wherein the frame 332 is fixedly connected to the bottom of the inner cylinder 310; wherein, The rotating shaft 331 has a first wiring space 3311 inside, and the frame 332 has a second wiring space 3323 inside; the conductive wire 343 passes through the first wiring space 3311 and the second wiring space 3323 in sequence, and exits from the end of the frame 332. Figure 13 The middle arrow indicates the threading path.
[0106] Specifically, the first wiring space 3311 is a central channel structure formed by axial routing along the pivot 331. The second wiring space 3323 extends radially and matches the shape of the frame 332. That is, after the conductive wire 343 enters the second wiring space 3323 from the first wiring space 3311, it can choose to exit in any one or more of the three directions formed by the frame 332, so as to adapt to the location of the functional components in the inner cylinder 310.
[0107] Furthermore, each end of the frame 332 is provided with a through hole 3324 to facilitate the passage of the conductive wire 343, which is beneficial to the neatness of the wire harness.
[0108] Furthermore, the frame 332 includes a support frame 3321 and a cover plate 3322 that interlock with each other. The support frame 3321 and the cover plate 3322 enclose the second wiring space 3323. The cover plate 3322 is located at the bottom of the frame 332 near the bottom of the inner cylinder 310. The detachable cover plate 3322 facilitates the laying of the conductive wires 343 and simplifies the assembly process.
[0109] Preferably, after the conductive wire 343 is threaded through the wiring channel, the wiring channel is filled with liquid silicone, and the wiring channel is sealed after the silicone cures. In one embodiment, combined with Figure 13 and Figure 14 As shown, the circuit board assembly 360 includes a bracket and a circuit board mounted on the bracket; wherein, The bracket is fixed to the outer ring of the bearing 350, and an opening 364 is formed on the side wall of the bracket; The electrical connection terminal 363 is formed on the circuit board, and the circuit board is mounted in the opening 364 so that the electrical connection terminal 363 contacts the conductive ring 340.
[0110] Furthermore, the shape of the opening 364 matches the shape of the circuit board, so that the circuit board can be snapped into the opening 364, enabling the circuit board assembly 360 to be quickly disassembled and assembled.
[0111] In one embodiment, the circuit board assembly 360 includes at least three sets of electrical connection terminals 363 for respectively implementing power supply, grounding, and signal line functions.
[0112] Preferably, each metal conductive area 341 is provided with a set of electrical connection terminals 363 to achieve the corresponding function. In this embodiment, the circuit board is provided with three sets of electrical connection terminals 363, each set including two electrical connection terminals 363, that is, the circuit board is provided with three pairs of electrical connection terminals 363. The conductive ring 340 is provided with three metal conductive areas 341 and three conductive wires 343. The electrical connection terminals 363 rub against the outer side of the annular metal conductive area 341. When the conductive ring 340 rotates, the electrical connection terminals 363 are used to maintain a continuous electrical connection. By setting the electrical connection terminals 363 in pairs, one is split into two, preventing one from being damaged while the other can still work. Furthermore, the two electrical connection terminals 363 in each set contact the same metal conductive area 341 from different directions to ensure its conductivity.
[0113] It should be understood that four, five or more sets of electrical connection terminals 363 can be set according to design requirements or actual functional needs, and the number of electrical connection terminals 363 for each set can be set according to different current intensities.
[0114] Furthermore, the electrical connection terminal 363 is configured as an elastic element, the end of which remains in contact with the conductive ring 340 under elastic action. Thus, even if wear occurs over time, the elastic element will remain in contact with the conductive ring 340 under elastic action to maintain good conductivity.
[0115] In one embodiment, two circuit board assemblies 360 are provided, which are snapped onto the bearing 350 to form an annular structure sleeved on the outer periphery of the conductive ring 340.
[0116] Furthermore, such as Figure 14As shown, the system includes a first circuit board assembly 361 and a second circuit board assembly 362. The first circuit board assembly 361 includes a first bracket 3611 and a first circuit board 3612 mounted on the first bracket 3611. The second circuit board assembly 362 includes a second bracket 3621 and a second circuit board 3622 mounted on the second bracket 3621. Both the first bracket 3611 and the second bracket 3621 are semi-annular structures, and when joined together, they form a complete annular structure. The first circuit board 3612 and the second circuit board 3622 are respectively positioned at the front... The circuit board is placed on the first support 3611 and the second support 3621. When the first circuit board assembly 361 and the second circuit board assembly 362 form a complete ring, the electrical connection terminals 363 on the first circuit board 3612 and the second circuit board 3622 respectively contact the corresponding metal conductive areas 341 from both sides of the conductive ring 340 to achieve conductivity. Specifically, in this embodiment, the first circuit board 3612 is provided with one set of electrical connection terminals 363, and the second circuit board 3622 is provided with two sets of electrical connection terminals 363. It should be understood that the specific arrangement of the electrical connection terminals 363 can be adjusted according to the actual functional design and usage.
[0117] This design facilitates the fixed installation of the first circuit board 3612 and the second circuit board 3622, while also allowing the circuit board assembly 360 to be easily fitted onto or removed from the outer periphery of the conductive ring 340 without disassembling the conductive ring 340 itself. On the other hand, the first bracket 3611 and the second bracket 3621 also provide excellent protection and dust prevention for the conductive ring 340, thereby further optimizing its conductivity.
[0118] In one embodiment, two bearings 350 are provided, which are respectively disposed at both ends of the conductive ring 340, and the circuit board assembly 360 is snapped onto the two bearings 350.
[0119] Furthermore, it also includes: an end cap 370, which is installed on the end of the conductive ring 340 and fixes the inner ring of the bearing 350 from the outside to protect the bearing 350 so that it can work normally; wherein, the end cap 370 and the conductive ring 340 are connected by fasteners.
[0120] In one embodiment, the functional components include one or more of a clamping device, a sterilization and drying device, a position sensor, a temperature sensor, and a humidity sensor.
[0121] This invention also provides a washing machine 300, combined with... Figures 9-15As shown, the device includes a power supply device for the inside of the drum of the washing machine 300 as described in Embodiment 1. When the washing machine 300 is running, the tripod 330 drives the inner drum 310 to rotate under the drive motor. The conductive ring 340 fixed to the end of the rotating shaft 331 rotates together with the tripod 330 and the inner drum 310, while the circuit board assembly 360 fixed to the outer ring of the bearing 350 of the rotating shaft 331 remains stationary relative to the outer drum 320. When the conductive ring 340 rotates, the electrical connection end 363 slides in contact with the conductive ring 340 to maintain a conductive state.
[0122] This embodiment enables power supply to the functional components inside the inner drum 310 while the inner drum 310 is rotating through the conductive ring 340 and the circuit board assembly 360. In this way, the cooperation between the rotating inner drum 310 and the functional components can expand the functions of the washing machine 300, optimize the overall functions of the washing machine 300, meet different user needs, and improve the user experience. Furthermore, this arrangement effectively avoids the wires from getting tangled during rotation. It has a simple structure, stable operation, and high reliability.
[0123] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0124] Example 4 This embodiment provides a washing machine inner drum 410, combined with...

The power supply device 440 is configured to maintain power supply to the power actuator 430 during the rotation of the inner cylinder 411 driven by the tripod 420.
[0125] In this embodiment, the power supply device 440 can supply power to the power actuator 430 installed in the inner drum 411 while the inner drum 411 is rotating. The power actuator 430 acts on the clothes inside the inner drum 411 to increase the washing power, such as driving the clothes to rotate back and forth to avoid tangling, strengthening rubbing and patting, etc., thereby improving the washing effect. In this way, the cooperation between the rotating inner drum 411 and the power actuator 430 can further expand the functions of the washing machine, optimize the overall functions of the washing machine, meet different user needs, and improve the user experience. Furthermore, the setting of passing the wiring terminal of the power supply device 440 through the hollow part inside the tripod 420 can effectively prevent the wire from getting tangled during rotation. Its structure is simple, stable in operation, and highly reliable.
[0126] The power supply device 440 is the same device used for powering the inside of the drum of a drum washing machine as described in Embodiment 1 or Embodiment 3.
[0127] Furthermore, the power supply device 440 includes an electrically connected conductive ring 441 and a fixed wiring portion 442; wherein, The conductive ring 441 is fixed to the end of the pivot 422 of the tripod 420 and rotates synchronously with the tripod 420; The fixed wiring portion 442 is installed on the housing located outside the inner cylinder 411 to contact the conductive ring 441 to achieve electrical connection, so as to conduct electricity during the rotation of the conductive ring 441 relative to the fixed wiring portion 442.
[0128] Furthermore, the conductive ring 441 includes multiple metal conductive regions 4411 and multiple conductive lines 4412 corresponding to the metal conductive regions 4411; wherein, An insulating plate 4413 is provided between adjacent metallic conductive regions 4411; One end of the conductive wire 4412 is electrically connected to the metal conductive area 4411, and the other end passes through the wiring channel 421 inside the tripod 420 to enter the inner cylinder 411 and connect to the power supply terminal of the power actuator 430.
[0129] In one embodiment, the fixed wiring part 442 includes a telescopic electromagnet 4421 and a pogopin circuit board 4422; wherein, the telescopic electromagnet 4421 includes an electromagnet body 44211, a cylindrical protrusion, a spring and a telescopic rod 44212, the electromagnet body 44211 has a mounting hole at its center, one end of the telescopic rod 44212 passes through the mounting hole and is provided with the spring at its end, and the other end is mounted on the cylindrical protrusion, the cylindrical protrusion serves as the output end of the telescopic electromagnet 4421, and the pogopin circuit board 4422 is mounted on the cylindrical protrusion; The working process of the telescopic electromagnet 4421 is as follows: Power off: When power is off, the telescopic electromagnet 4421 is in a non-working state, and the telescopic rod 44212 is in a non-extended state, retracted inside the electromagnet; Power on: When the main control board of the washing machine is powered, the telescopic electromagnet 4421 is in working state, the telescopic rod 44212 is subjected to the magnetic force of the electromagnet, and the magnetic force is greater than the spring force, so the telescopic rod 44212 pops out and maintains the set travel distance.
[0130] It should be noted that the above-mentioned fixed wiring part 442 is a telescopic structure. Depending on the different inner drum structures and the actual design of the washing machine, the fixed wiring part 442 can also be set as a swing structure, a rotation structure or a linear movement structure driven by a motor or electric push rod, etc. That is, any scheme that can achieve contact and separation between the conductive ring 441 and the fixed wiring part 442 is within the protection scope of this invention.
[0131] In another embodiment, the fixed wiring portion 442 includes a bracket 4423 and a circuit board 4424 fixed to the bracket 4423; wherein, The bracket 4423 is rotatably mounted to the conductive ring 441 via a bearing 443, and an opening 44231 is formed on the side wall of the bracket 4423; The circuit board 4424 is installed in the opening 44231, and the circuit board 4424 has an electrical connection end 44241 on the side facing the conductive ring 441, which is always in contact with the side wall of the conductive ring 441 to achieve conductivity during the rotation of the conductive ring 441 relative to the bracket 4423.
[0132] In one embodiment, the power actuator 430 includes one or more of a clamping device, a stirring device, an agitating device, and a lifting device. Specifically, the clamping device can grip and unfold the clothes to increase the contact area between the washing water and the clothes, or facilitate faster drying during the drying process. The stirring or agitating device can increase the kneading effect on the clothes, and the lifting device can increase the beating effect on the clothes to prevent them from clumping together, thereby effectively improving the washing cleanliness of the washing machine and enabling diversified washing methods.
[0133] In one embodiment, the power actuator 430 is mounted on the side wall of the inner cylinder 411.
[0134] Furthermore, the power actuator 430 is installed on the inner wall of the inner drum 411; for example, it is a clamping device and a tossing device that provide power to the items inside the drum during the rotation or non-rotation of the inner drum 411, so as to accelerate the washing process.
[0135] Furthermore, the power actuator 430 is distributed on the outer wall of the inner cylinder 411; for example, a cleaning device that can serve as an outer barrel 412 is provided on the outer wall of the inner cylinder 411. Specifically, the cleaning device includes a retractable cleaning brush. When the cleaning process is performed, the cleaning brush is controlled to extend and its bristles are brought into contact with the inner wall of the outer barrel 412 to clean the inner wall of the outer barrel 412 when the inner cylinder 411 rotates. The cleaning process ends when the cleaning brush is controlled to return to its original position.
[0136] In one embodiment, such as Figure 19 and Figure 20 As shown, the inner drum 411 also includes lifting ribs 4111, and the power actuator 430 is installed with the lifting ribs 4111. Specifically, the power actuator 430 can be installed inside or outside the lifting ribs 4111; during the rotation of the inner drum 411, the traction of the power actuator 430, combined with the lifting and beating action of the lifting ribs 4111 on the clothes, further improves the cleaning effect on the clothes.
[0137] Furthermore, the power actuator 430 is installed inside the lifting rib 4111, and after operation, the power actuator 430 is concealed within the lifting rib 4111. Specifically, the lifting rib 4111 has an installation port, the power actuator 430 is installed inside the lifting rib 4111, and its actuating end extends out of the lifting rib 4111 through the installation port to act on the clothing; the arrangement of concealing the power actuator 430 within the lifting rib 4111 optimizes the structural layout of the inner tube 411 and is also beneficial to the aesthetics of the inner tube 411.
[0138] In another embodiment, the power actuator 430 is installed at the bottom of the inner drum 411 to provide power to the items inside the bottom of the drum during the rotation or non-rotation of the inner drum 411. For example, it can be used as a clamping device and a tossing device. It can shake the clothes at the bottom of the drum and prevent the clothes from clumping together during the washing process, thereby speeding up the washing. Alternatively, a cleaning device that can be used as the inner wall of the bottom of the outer drum 412 can be provided on the outer wall of the bottom of the inner drum 411.
[0139] A washing machine includes an inner drum 410 as described above.
