[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] like Figure 1-12 As shown, a rotary power washing machine drive assembly and a washing machine, comprising:

[0040] The reducer 23 has an input end connected to the output end of the motor 1, and the output end of the reducer 23 includes a fixed disk 2341 and a central shaft 2342;

[0041] The pulsator barrel 3 is fixedly connected to the central shaft 2342;

[0042] The inner wall barrel 4 is rotatably connected to the pulsator barrel 3;

[0043] The splitter speed change mechanism 2 comprises a conical speed change disc 21 and a drive shaft 25 symmetrically arranged on a fixed disc 2341, a belt 24 is arranged between the conical speed change disc 21 and the drive shaft 25, and the drive shaft 25 is coupled to the inner wall barrel 4;

[0044] The inner wall barrel 4 is driven to rotate and shake, so as to increase the distance between the two conical speed change discs 21, so as to reduce the coupling distance between the belt 24 and the two conical speed change discs 21;

[0045] It also includes a shell 5, the pulsator barrel 3 and the inner wall barrel 4 are arranged in the shell 5, and an upper cover 51 for sealing the inner wall barrel 4 is arranged on the shell 5.

[0046] Specifically, there are two conical speed change discs 21, one of which is fixedly arranged on the fixed disc 2341 (with Figure 2 For reference, the lower end is close to the motor 1), the other conical speed change disc 21 is slidably connected to the fixed disc 2341, and a spring 22 is provided between the two conical speed change discs 21. The spring 22 is used to control the default spacing between the two conical speed change discs 21 to control the diameter of the arc profile formed by the belt 24 fitting the conical speed change discs 21. When there is no large load, the default speed of the inner wall barrel 4 is maintained, and when the overload of the inner wall barrel 4 is large, the force of pulling the belt 24 will increase. The two conical speed discs 21 are added to offset the pulling force of the spring 22, squeezing the two conical speed discs 21 away from each other to move the deceleration inner wall barrel 4 away from each other. During use, when the inner wall barrel 4 shakes due to excessive amount of clothes, the distance between the two conical speed discs 21 will increase and pull the spring 22. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed disc 21 will decrease, causing the speed ratio of the drive shaft 25 and the conical speed disc 21 to change, thereby driving the inner wall barrel 4 to slow down and avoid damage due to excessive load.

[0047] In the above technical solution, the belt 24 is driven to rotate by the rotation of the conical speed change disc 21 to drive the driving shaft 25 to rotate, thereby coupling the inner wall barrel 4 and the pulsator barrel 3 to rotate in the opposite direction, forming a rotational force to wash the clothes. When the single washing volume is too large, causing the inner wall barrel 4 to shake, the distance between the two conical speed change discs 21 will increase, thereby squeezing the belt 24 along the outer ring of the conical speed change disc 21 to the inner ring, so as to reduce the coupling distance between the belt 24 and the two conical speed change discs 21, thereby slowing down the inner wall barrel 4 to reduce the shaking of the inner wall barrel 4 and prevent damage.

[0048] Furthermore, the shell 5 is a plastic shell, and a balance ring 40 is provided on the inner wall barrel 4, and the balance ring 40 is used to reduce shaking.

[0049] As an embodiment provided by the present invention, the reducer 23 includes a ring gear, in which a primary sun tooth 231 and a secondary sun tooth 233 are coaxially arranged, a planetary gear 232 is arranged between the primary sun tooth 231 and the secondary sun tooth 233, a planetary carrier 234 is arranged on the planetary gear 232 coupled to the secondary sun tooth 233, a fixed plate 2341 is arranged on the planetary carrier 234, and a center shaft 2342 is arranged on the secondary sun tooth 233.

[0050] Specifically, the primary sun gear 231 is arranged at the output end of the motor 1, and the number of planetary gears 232 is two groups, which are respectively coupled to the primary sun gear 231 and the secondary sun gear 233. The planetary gear 232 coupled to the primary sun gear 231 is rotatably connected to the secondary sun gear 233 to realize multiple decelerations to reduce the burden on the motor 1. The central shaft 2342 is arranged on the secondary sun gear 233, and the central shaft 2342 is fixedly connected to the impeller barrel 3, driving the impeller barrel 3 to rotate at a higher speed than the inner wall barrel 4, and the rotating planetary carrier 234 transmits power to the driving shaft 25 through the belt 24, so that the driving shaft 25 rotates and couples to transmit power to the inner wall barrel 4, and an elastic ring 251 is arranged on the driving shaft 25, and the elastic ring 251 fits the outer wall of the inner wall barrel 4 to realize driving.

[0051] Furthermore, it also includes a tensioning roller 241 movably arranged in the shell 5. The tensioning roller 241 is pulled by an elastic member (the elastic member can be a tension spring, etc.) to fit the inner side of the belt 24 to ensure that the belt 24 keeps the belt 24 tensioned to transmit power when the diameter of the arc contour formed by the conical speed change plate 21 changes.

[0052] As an embodiment provided by the present invention, the splitter speed change mechanism 2 further includes a flip detection rod 26, and a push plate 20 is provided on the conical speed change plate 21. The detection rod 26 flips with the shaking of the inner wall barrel 4 to push the push plate 20 to move in the vertical direction, so as to increase the distance between the two conical speed change plates 21.

[0053] A rotation center 261 is provided on the detection rod 26 , and the detection rod 26 rotates along the rotation center 261 to push against the push plate 20 .

[0054] Specifically, a push plate 20 is provided on the conical speed change plate 21 near the pulsator barrel 3, and a rotation center 261 on the detection rod 26 is rotatably connected to the inner wall of the housing 5. The detection rod 26 is made of elastic metal. Figure 7For reference, the second end is the lower end) and is clamped on the push plate 20. When the inner wall barrel 4 shakes, the upper end of the inner wall barrel 4 shakes more greatly. At this time, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change plate 21 to slide along the fixed plate 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change plates 21 to reduce the diameter of the arc contour formed by the belt 24 fitting the conical speed change plate 21.

[0055] The detection rod 26 adjusts the spacing of the conical speed change discs 21 by shaking, and the belt 24 adjusts the spacing of the conical speed change discs 21 by load pulling, and both can perform overload protection.

[0056] When there is no heavy load, the inner wall barrel 4 maintains its default speed rotation. During use, when the inner wall barrel 4 shakes due to excessive amount of clothes, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change plate 21 to slide along the fixed plate 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change plates 21. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed change plate 21 will decrease, resulting in a change in the speed ratio of the drive shaft 25 and the conical speed change plate 21, thereby driving the inner wall barrel 4 to slow down.

[0057] As an embodiment provided by the present invention, a first water-displacing protrusion 31 is arranged in a circular array in the pulsator tub 3, and a connected water collecting groove 311 and a water outlet 313 are symmetrically arranged on the first water-displacing protrusion 31. The water collecting groove 311 collects water flow and sprays it out from the water outlet 313 as the pulsator tub 3 rotates.

[0058] Specifically, the first water-discharging protrusion 31 is used to stir the water flow along with the pulsator barrel 3. The first water-discharging protrusion 31 is symmetrically provided with a connected water collecting groove 311 and a water outlet hole 313. The first water-discharging protrusion 31 is provided with an inclined water outlet groove 312. A plurality of water outlet holes 313 face the inclined water outlet groove 312 to guide the water flow to be sprayed out obliquely. When the washing machine is running, forward rotation, stop and reverse rotation steps are performed, and the washing mode is changed by adjusting the time and speed of forward rotation, stop and reverse rotation. When washing small-sized clothes (such as underwear, socks, hats, etc.) and when the amount of clothes and water is small, the symmetrical water collecting groove 311 will collect water along with the forward rotation and reverse rotation steps, and spray water from the corresponding water outlet hole 313 to assist in impacting the clothes, so as to increase the friction efficiency of the small-sized clothes and increase the mixed flow. The direction of the sprayed water flow is the same as the rotation direction of the pulsator barrel 3 and opposite to the rotation direction of the inner wall barrel 4, so as to increase the counter-flow, further increase the friction efficiency of the small-sized clothes, and improve the cleaning ability.

[0059] When there is no heavy load, the inner wall barrel 4 is kept rotating at the default speed. When low-load washing is performed, the water collecting tank 311 collects water along the forward and reverse steps, and sprays water from the corresponding water outlet 313 to assist in impacting the clothes. During use, when the inner wall barrel 4 shakes due to excessive amount of clothes, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change disc 21 to slide along the fixed disc 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change discs 21. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed change disc 21 will decrease, resulting in a change in the speed ratio of the drive shaft 25 and the conical speed change disc 21, thereby driving the inner wall barrel 4 to slow down.

[0060] As an embodiment provided by the present invention, a shielding slide plate 32 is slidably connected to the first water-deflecting protrusion 31, and a rotating disk 321 rotatably connected to one of the conical speed change disks 21 is provided on the shielding slide plate 32. As the distance between the two conical speed change disks 21 increases, the rotating disk 321 drives the shielding slide plate 32 to shield the water collecting trough 311.

[0061] Specifically, a rotating disk 321 is provided on the shielding slide plate 32, and the rotating disk 321 is rotatably connected to the rotating groove 201 opened on the push plate 20. The rotating disk 321 rotates together with the pulsator barrel 3, and the water outlet hole 313 sprays out in the opposite direction of the rotation of the inner wall barrel 4, thereby increasing the cleaning ability, but also increasing the load on the inner wall barrel 4. When the load is large, the shielding slide plate 32 will slide upward on the push plate 20 to shield the water collecting tank 311, such as Fig.11 As shown, the load on the inner wall barrel 4 is reduced, and the probability of damage to the inner wall barrel 4 is further reduced.

[0062] When there is no heavy load, the inner wall barrel 4 is kept rotating at the default speed. When low-load washing is performed, the water collecting tank 311 collects water with the forward and reverse steps, and sprays water from the corresponding water outlet 313 to assist in impacting the clothes. During use, when the inner wall barrel 4 shakes due to excessive amount of clothes, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change disc 21 to slide along the fixed disc 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change discs 21. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed change disc 21 will decrease, resulting in a change in the speed ratio of the drive shaft 25 and the conical speed change disc 21, thereby driving the inner wall barrel 4 to slow down. At the same time, the shielding slide plate 32 will move upward along with the sliding on the push disc 20 to shield the water collecting tank 311.

[0063] As an embodiment provided by the present invention, the inner wall barrel 4 is hollow, and the inner wall barrel 4 is provided with a second water-displacing protrusion 43 and a water outlet 44 in a circumferential array, and the second water-displacing protrusion 43 is symmetrically provided with a water receiving port 431, and the water receiving port 431 collects water as the inner wall barrel 4 rotates and sprays it out along the water outlet 44;

[0064] An elastic cover 432 for sealing the water receiving port 431 is symmetrically arranged on the second water-repelling protrusion 43 .

[0065] Specifically, the elastic cover 432 fits against the water receiving port 431 to seal it, preventing the water in the inner wall barrel 4 from flowing out of the water receiving port 431. When the inner wall barrel 4 rotates, the elastic cover 432 will open with the impact of the water flow in the rotation direction to achieve one-way entry of water. The incoming water continues and is sprayed out along the water outlet 44 to cooperate with the water flow sprayed from the water outlet 313 to form a fine mixed flow, thereby further increasing the cleaning efficiency for small-sized clothes. Moreover, when rotating in both directions, water can be collected and sprayed out from the water outlet 44.

[0066] When there is no heavy load, the inner wall barrel 4 is kept rotating at the default speed. When low-load washing is performed, the water collecting tank 311 collects water with the forward and reverse steps, and sprays water from the corresponding water outlet 313 to assist in impacting the clothes. At the same time, when the inner wall barrel 4 rotates, the elastic cover 432 opens with the impact of the water flow in the rotating direction to achieve unidirectional water entry, and the entered water continues to be sprayed along the water outlet 44 to form a fine mixed flow with the water flow sprayed from the water outlet 313. In the process of use, due to the excessive amount of clothes, the inner wall barrel 4 When shaking, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change plate 21 to slide along the fixed plate 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change plates 21. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed change plate 21 will decrease, causing the speed ratio of the drive shaft 25 and the conical speed change plate 21 to change, thereby driving the speed of the inner wall barrel 4 to slow down. At the same time, the shielding slide plate 32 will move upward along with the sliding on the push plate 20 to shield the water collecting trough 311.

[0067] As the best embodiment provided by the present invention, an intermediate ring 41 is rotatably connected between the inner wall barrel 4 and the pulsator barrel 3, and an elastic column 45 is arranged between the intermediate ring 41 and the inner wall barrel 4. The inner wall barrel 4 is restricted by the water flow to drive the elastic column 45 to bend, so as to drive the water outlet 44 to be blocked;

[0068] The middle ring 41 is provided with shielding plates 42 in a circumferential array, and the elastic column 45 is driven to bend to drive the inner wall barrel 4 and the middle ring 41 to be misaligned, so as to drive the shielding plates 42 to slide and fit the second water-repelling protrusion 43 to block.

[0069] Specifically, an elastic column 45 is arranged between the middle ring 41 and the inner wall barrel 4, and the middle ring 41 is coupled to the driving shaft 25 for rotation. When running at low load, the elastic column 45 drives the middle ring 41 and the inner wall barrel 4 to rotate synchronously. At this time, the baffle plate 42 and the second water-repelling protrusion 43 are blocked and misaligned to maintain the normal operation of the second water-repelling protrusion 43. When washing large clothes (large clothes such as quilts, coats, cotton clothes, etc.), the ability to stir the water flow will be weakened, and the load of the inner wall barrel 4 will increase, causing the elastic column 45 to bend, resulting in misalignment between the inner wall barrel 4 and the middle ring 41, so that the baffle plate 42 slides and fits the second water-repelling protrusion 43 to block. At this time, the second water-repelling protrusion 43 will not discharge water. Blocking the holes can reduce the impact on large clothes and reduce mixing, thereby reducing the occurrence of entanglement and reducing the load of the inner wall barrel 4.

[0070] When there is no heavy load, the inner wall barrel 4 is kept rotating at the default speed. When low-load washing is performed, the water collecting tank 311 collects water with the forward and reverse steps, and sprays water from the corresponding water outlet 313 to assist in impacting the clothes. At the same time, when the inner wall barrel 4 rotates, the elastic cover 432 opens with the impact of the water flow in the rotation direction to achieve one-way entry of water flow. The incoming water continues and is sprayed along the water outlet 44 to form a fine mixed flow with the water flow sprayed from the water outlet 313. When washing large-sized clothes, the load of the inner wall barrel 4 will increase, causing the elastic column 45 to bend, resulting in misalignment between the inner wall barrel 4 and the middle ring 41, so that the baffle plate 42 slides and fits the second water-repelling convex The inner wall barrel 4 is blocked by the belt 24, and the load on the inner wall barrel 4 is reduced. When the inner wall barrel 4 shakes due to excessive amount of clothes during use, the upper end of the shaking inner wall barrel 4 pushes the detection rod 26 to flip, so that the detection rod 26 flips and lifts the second end to push the conical speed change plate 21 to slide along the fixed plate 2341 in the vertical direction and pull the spring 22, thereby expanding the two conical speed change plates 21. At this time, the diameter of the arc contour formed by the belt 24 fitting the conical speed change plate 21 will be reduced, resulting in a change in the speed ratio of the drive shaft 25 and the conical speed change plate 21, thereby driving the inner wall barrel 4 to slow down. At the same time, the shielding slide plate 32 will move upward along with the sliding on the push plate 20 to shield the water collecting tank 311.

[0071] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
