Description

Technical Field

[0001] The present invention relates to the technical field of self-cleaning washing machines, and in particular to a washing machine with no dead corners for dirt to be hidden in an inner barrel, and also to a deceleration clutch with only a single power output installed in the above-mentioned washing machine. Background Art

[0002] The impeller and the bottom of the barrel of an existing fully automatic impeller washing machine are driven by different drive shafts. The impeller can rotate relative to the bottom of the barrel. Therefore, there is a gap between the impeller and the bottom of the barrel. In addition, the bottom of the impeller generally has more reinforcing ribs. As the washing machine is used for a longer time, dirt and grime are likely to accumulate between the impeller and the bottom of the barrel.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a washing machine deceleration clutch with a simple and compact structure, low manufacturing cost, safe and reliable transmission, high efficiency, long service life, and low noise. Another object of the present invention is to provide a washing machine with such a deceleration clutch to eliminate dead corners in the inner drum where dirt can accumulate.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A washing machine includes an inner tub, wherein the bottom of the inner tub is provided with a protrusion protruding into the tub, rotating at the same speed as the inner tub, and used to shift the water flow; a deceleration clutch including a transmission structure and a clutch device, wherein the input end of the transmission structure is connected to a drive motor and the output end is connected to the inner tub, and the clutch device changes the meshing relationship of the transmission structure and adjusts the transmission ratio between the input end and the output end.

[0007] Furthermore, the transmission structure has a single output end for outputting all the power input into the transmission structure to the inner barrel.

[0008] Furthermore, the clutch device is used to convert the transmission ratio of the transmission structure when the washing machine is in the washing mode and the dehydration mode.

[0009] Furthermore, when the washing machine is in the washing mode, the input end and the output end of the transmission structure rotate at a differential speed; when the washing machine is in the dehydration mode, the input end and the output end of the transmission structure rotate at the same speed.

[0010] Furthermore, the transmission structure includes a reduction gearbox, in which a transmission gear set is installed, and an input shaft and an output shaft are respectively inserted into the opposite sides of the reduction gearbox, the input shaft is connected to the rotor of the drive motor, and the output shaft is coaxially connected to the bottom of the inner barrel, and the input shaft and the output shaft are inserted into one end of the reduction gearbox and meshed with the transmission gear set; preferably, the input shaft and the output shaft are both coaxially arranged with the reduction gearbox.

[0011] Furthermore, the clutch device is used to adjust the meshing relationship between gears within the transmission gear set, and / or between the transmission gear set and the input shaft, and / or between the transmission gear set and the output shaft, thereby adjusting the transmission ratio between the input shaft and the output shaft. Preferably, the transmission gears in the transmission gear set are mounted on the wheel carrier, and the clutch device is used to adjust the meshing relationship between the wheel carrier and the input shaft, the output shaft, the reduction gearbox, and the reduction clutch housing, thereby adjusting the transmission ratio between the input shaft and the output shaft.

[0012] Furthermore, the clutch device includes a clutch sleeve and a drive device. The clutch sleeve is installed on the input shaft or the output shaft for joint rotation. The drive device drives the clutch sleeve to move axially along the input shaft or the output shaft, so that the clutch sleeve engages with different gears of the transmission gear set, causing the input shaft and the output shaft to rotate at the same speed or at a differential speed.

[0013] Furthermore, the clutch device includes a clutch sleeve and a drive device. The clutch sleeve is connected to at least one transmission gear in the transmission gear set. The drive device drives the clutch sleeve to move, causing the at least one transmission gear in the transmission gear set to mesh with a different transmission gear via the clutch sleeve, thereby causing the input shaft and the output shaft to rotate at the same speed or at a differential speed. Preferably, the clutch sleeve is connected to a wheel carrier on which a transmission gear of any stage in the transmission gear set is mounted. The drive device drives the clutch sleeve to move, causing the wheel carrier to mesh with the input shaft, the output shaft, the reduction gearbox, or the reduction clutch housing via the clutch sleeve, thereby causing the input shaft and the output shaft to rotate at the same speed or at a differential speed.

[0014] Furthermore, the clutch device is used to engage or disengage the output shaft with the housing of the reduction gearbox, and the output shaft is driven and engaged with the input shaft through the transmission gear set and rotates at a differential speed; or, the output shaft is directly driven and engaged with the input shaft through the reduction gearbox and rotates at the same speed.

[0015] Further, the transmission gear set is any one of a two-stage planetary gear transmission mechanism, a two-stage double-tooth internal gear or outer planetary gear or inner planetary gear transmission mechanism, a three-stage double-tooth outer gear transmission mechanism, a one-stage internal gear or outer gear transmission mechanism, a small tooth difference planetary gear or cycloid pinwheel transmission mechanism, a single internal gear different planetary shaft or double internal gear concentric shaft transmission mechanism.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0017] The inner drum of the washing machine of the present invention eliminates the impeller that can rotate relative to the inner drum, and instead has a barrel bottom protrusion that protrudes toward the interior of the inner drum sealedly assembled on the inner surface of the barrel bottom or integrally formed therewith, and / or a barrel body protrusion that protrudes toward the interior of the inner drum sealedly assembled on the inner surface of the barrel body or integrally formed therewith. During washing, the inner drum rotates, driving the barrel bottom protrusion to drive the water flow and the clothes to move, thereby achieving the purpose of washing and rinsing.

[0018] The present invention provides a highly efficient, simple, reliable, single-power-output deceleration clutch with adjustable transmission ratio and a washing machine application, thereby improving the transmission efficiency and reducing energy consumption. The deceleration clutch of the present invention has a simple structure and high reliability, improving the performance of the washing machine.

[0020] At the same time, a clutch device is provided on the above-mentioned deceleration clutch, so that under the action of the clutch device, the input shaft is engaged with the output shaft through the transmission gear set and rotates differentially, or the input shaft is engaged with the output shaft through the reduction gear box and rotates at the same speed.

[0021] The clutch device described above controls the engagement and disengagement of a reduction clutch having only a single output end, adjusting the output shaft speed, thereby achieving the effect of controlling the adjustable speed rotation of an inner tub integrally mounted or fixedly connected to a pulsator, thereby enabling a washing machine equipped with such an inner tub to perform either a washing or a spin cycle. The present invention further improves the clutch device, ensuring that its clutch mechanism does not fail, has a long service life, is low in noise, and reduces manufacturing costs.

[0022] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 16 As shown, the present invention introduces a washing machine, which includes an inner tub, and a protrusion at the bottom of the inner tub is provided, which protrudes into the tub and rotates at the same speed as the inner tub and is used to stir the water flow, and the protrusion rotates at the same speed as the inner tub; the inner tub is connected to the driving motor of the washing machine via a reduction clutch to transmit the power of the driving motor to the inner tub via the only output end of the reduction clutch to drive the inner tub to rotate, and the inner tub and the protrusion provided on the bottom of the inner tub stir the washing water and / or clothes in the tub to form a water flow, and the water flow is used to treat the clothes.

[0029] The washing machine deceleration clutch described in the present invention includes a transmission structure and a clutch device. The input end of the transmission structure is connected to the drive motor, and the output end is connected to the inner tub. The clutch device changes the engagement relationship of the transmission structure and adjusts the transmission ratio between the input end and the output end.

[0030] The transmission structure of the deceleration clutch in the present invention can be any structure or combination that can transmit power in the prior art, such as a gear transmission structure, a rack transmission structure, a pulley transmission structure, a chain transmission structure, etc.

[0031] The transmission structure of the deceleration clutch in the present invention has only a single output end, which is used to output all the power input into the transmission structure to the inner barrel, so that the power input into the drive motor is all used to drive the inner barrel to rotate through the single output end.

[0032] The clutch mechanism of the speed reduction clutch of the present invention is used to change the transmission ratio of the transmission structure between the washing machine's wash and spin modes. Under the action of the clutch mechanism, the input and output ends of the transmission structure rotate at different speeds when the washing machine is in the wash mode; when the washing machine is in the spin mode, the input and output ends of the transmission structure rotate at the same speed.

[0033] The transmission ratio of the transmission structure is adjusted through the clutch device to adjust the speed of the inner drum, thereby achieving the effect of driving the inner drum to rotate at different speeds to perform the washing or dehydration process of the washing machine.

[0034] Example 1

[0035] like Figures 1 to 16 As shown, this embodiment introduces a deceleration clutch 200 applied to the above-mentioned washing machine, including a transmission structure 300 and a clutch device 400. The input end of the transmission structure 300 is connected to the drive motor 5, and the output end is connected to the inner drum 100. The clutch device 400 changes the engagement relationship of the transmission structure 300 and adjusts the transmission ratio between the input end and the output end so that the power of the drive motor is fully transmitted to the inner drum in the form of an adjustable transmission ratio, thereby achieving the effect of driving the inner drum to rotate at different speeds.

[0036] In this embodiment, the transmission structure 300 of the deceleration clutch 200 includes a deceleration gearbox 3, in which a transmission gear set 14 is installed. An input shaft 1 and an output shaft 2 are respectively inserted on opposite sides of the deceleration gearbox 3. The input shaft 1 is connected to the rotor of the drive motor 5, and the output shaft 2 is coaxially connected to the bottom of the inner barrel 100. The input shaft 1 and the output shaft 2 are inserted into one end of the deceleration gearbox 3 and meshed with the transmission gear set 14; preferably, the input shaft 1 and the output shaft 2 are both coaxially arranged with the deceleration gearbox 3.

[0037] In this embodiment, the clutch device 400 is used to adjust the meshing relationship between the internal gears of the transmission gear set 14, and / or between the transmission gear set 14 and the input shaft 1, and / or between the transmission gear set 14 and the output shaft 2, thereby achieving the effect of adjusting the transmission ratio between the input shaft 1 and the output shaft 2.

[0038] In this embodiment, the clutch device 400 includes a clutch sleeve 4 and a driving device. The clutch sleeve 4 is displaced under the action of the driving device, so that the moving clutch sleeve 4 is used to adjust the meshing relationship between the internal gears of the transmission gear set 14, and / or between the transmission gear set 14 and the input shaft, and / or between the transmission gear set 14 and the output shaft 2, thereby achieving the effect of adjusting the transmission ratio between the input shaft 1 and the output shaft 2.

[0039] In this embodiment, the driving device of the clutch device 400 includes a clutch motor that provides a driving force, and transmits the displacement of the clutch motor output terminal to the clutch transmission structure at the clutch sleeve 4. The clutch transmission structure can be any structure in the prior art that can drive the clutch sleeve 4 to move, such as a shift fork structure, a clutch pressure plate structure, a clutch cam structure, etc.

[0040] At the same time, in order to ensure the common speed connection between the clutch sleeve 4 and other components, meshing teeth and other structures can be provided on the clutch sleeve 4, and relatively meshing meshing teeth and other structures can be provided on the corresponding internal gears constituting the transmission gear set 14, and / or the input shaft 1, and / or the output shaft 2, and / or the housing 13 of the reduction clutch, and / or the rotor of the drive motor 5, thereby achieving a common speed meshing connection between the clutch sleeve 4 and other components.

[0041] In this embodiment, the clutch sleeve 4 can be installed on the input shaft 1 or the output shaft 2 for common rotation. The driving device drives the clutch sleeve 4 to move axially along the input shaft 1 or the output shaft 2, so that the clutch sleeve 4 engages with different gears of the transmission gear set 14, so that the input shaft 1 and the output shaft 2 rotate at the same speed or at a differential speed.

[0042] In this embodiment, the clutch sleeve 1 can also be connected to at least one transmission gear 8 in the transmission gear set 14. The driving device drives the clutch sleeve 4 to move, so that at least one transmission gear 8 in the transmission gear set 14 engages with a different transmission gear 8 through the clutch sleeve 4, so that the input shaft 1 and the output shaft 2 rotate at the same speed or at a differential speed.

[0043] In this embodiment, the clutch sleeve 4 can also engage or disengage the output shaft 2 with the reduction gear box 3, and the output shaft 2 is driven and engaged with the input shaft 1 through the transmission gear set 14 and rotates at a differential speed; or, the output shaft 2 is directly driven and engaged with the input shaft 1 through the reduction gear box 3 and rotates at the same speed.

[0044] In this embodiment, the clutch sleeve 4 can also engage or disengage the reduction gear box 3 with the housing 13 of the reduction clutch, and the output shaft 2 is driven and engaged with the input shaft 2 through the transmission gear set 14 and rotates at a differential speed; or, the output shaft 2 is directly driven and engaged with the input shaft 2 through the reduction gear box 3 and rotates at the same speed.

[0045] In this embodiment, the clutch sleeve 4 can also be connected to the wheel carrier 7 mounted with the transmission gear 8 of any stage in the transmission gear set 14. The driving device drives the clutch sleeve 4 to move, so that the wheel carrier 7 engages with the input shaft 1, or the output shaft 2, or the reduction gear box 3, or the reduction clutch housing 13 through the clutch sleeve 4, so that the input shaft 1 and the output shaft 2 rotate at the same speed or at a differential speed.

[0046] In this embodiment, the transmission gear set 14 installed inside the reduction gear box 3 can be any structure in the prior art, such as Figures 5 to 16 The structure shown is, for example, any of a two-stage planetary gear transmission, a two-stage double-toothed internal gear ring or outer planetary gear or inner planetary gear transmission, a three-stage double-toothed external gear transmission, a single-stage internal gear ring or outer gear transmission, a small-tooth-difference planetary gear or cycloid pinwheel transmission, a single internal gear ring with different planetary shafts, or a double internal gear ring with concentric shafts. However, it is necessary to ensure that the output end of the reduction gearbox 3 is uniquely provided, and the output end of the reduction clutch 200 is the output shaft 2 connected to the washing machine inner drum 100.

[0047] like Figure 5 The washing machine deceleration clutch consists of an input shaft 1, an output shaft 2, an input shaft sleeve, a reduction gear box 3 and a transmission gear set 14 installed inside the reduction gear box 3, which is a dual-drive gear mechanism. The input shaft 1 is installed in the input shaft sleeve 38, and the input shaft sleeve 38 is fixed to the lower end of the reduction gear box 3. The wheel frame 7 is fixed on the input shaft sleeve 38. The input shaft 1 is engaged with the center wheel 6, and the center wheel 6 is engaged with the inner ring gear 9 through at least one stage of transmission gear 8. The inner ring gear 9 is connected to the output shaft 2 to form a dual-drive gear mechanism. A clutch device 400 is installed between the reduction gear box 3 and the output shaft 2.

[0048] like Figure 6 The transmission gear set 14 of the washing machine's deceleration clutch is a two-stage planetary gear transmission mechanism. It consists of a center gear 6, upper planetary gears 33, an inner ring gear 9, a planet carrier 311, lower planetary gears 310, a center gear 39, and a wheel carrier 7. The input shaft 1 is connected to the center gear 6. The upper planetary gears 33 are mounted on the planet carrier 35 and mesh with the center gear 6. The inner ring gear 9 is connected to the output shaft 2. The lower planetary gears 310 are mounted on the wheel carrier 7. The inner ring gear 9 meshes with the upper and lower planetary gears 33 and 310, serving as a common gear for both sets of planetary gears. The upper and lower planetary gears can each have 2 to 6 gears. The upper planetary gears 33 are connected to the planet carrier 311. A clutch device 400 is installed between the reduction gearbox 3 and the inner ring gear 9. During washing operation, the reduction gearbox 3 is fully braked, causing the upper planetary gears 33 to both orbit and rotate, while the lower planetary gears 310 only rotate.

[0049] When dehydration is in progress, the reduction gearbox 3 is completely released, and the drive motor rotates continuously in one direction as required. Through the locking action of the clutch device 400 connected between the reduction gearbox 3 and the output shaft 2, the reduction clutch is automatically combined into a whole to complete the centrifugal dehydration process without the need for a complete set of clutch components and operating mechanisms of a conventional reduction clutch.

[0050] like Figure 7The transmission gear set 14 of the washing machine's deceleration clutch is a two-stage, double-linked internal gear transmission mechanism. This mechanism consists of a center wheel 6, an internal gear ring 9, double-linked planetary gears 321, and a wheel carrier 7. The double-linked planetary gears 321 are mounted on the wheel carrier 7, with their lower teeth meshing with the center wheel 6 and their upper teeth meshing with the internal gear ring 9. The input shaft 1 is connected to the center wheel 6, and the output shaft 2 is connected to the internal gear ring 9. There can be two to six double-linked planetary gears. A clutch device 400 is installed between the reduction gearbox 3 and the internal gear ring 9. During washing operation, the reduction gearbox 3 is fully braked, the wheel carrier 7 is in a fixed axis state, and the drive motor drives the center wheel 6 and the double-linked planetary gears 321 to rotate repeatedly in both directions. At the same time, through the internal gear ring 9, the output shaft 2 is also driven, rotating repeatedly in both directions proportionally and oscillating at a low speed, thus completing the washing process.

[0051] like Figure 8 The washing machine's deceleration clutch transmission gear set 14 is a two-stage, double-toothed outer planetary gear transmission mechanism. This mechanism consists of a center gear 6, outer planetary gears 30, wheel carrier 7, planetary carrier 311, double-linked planetary gears 321, center gear 39, and wheel carrier 7. The double-linked planetary gears 321 are mounted on wheel carrier 7, and the outer planetary gears 33 are mounted on planetary carrier 311. There are two to six double-linked planetary gears 321 and outer planetary gears 30, respectively. The upper and lower teeth of the double-linked planetary gears 321 mesh with the outer planetary gears 30 and center gear 6, respectively. The center gear 6 is connected to the input shaft 1, and the outer planetary gears 30 mesh with the output shaft 2 via the center gear 39. A clutch device 400 is installed between the reduction gearbox 3 and the center gear 39. When the washing process is in progress, the reduction gearbox 3 is completely braked, the wheel frame 7 is in a fixed axis state, and the driving motor 5 drives the center wheel 6 and the double planetary gear 321 to rotate repeatedly in both directions. At the same time, the output shaft 2 is driven through the outer planetary wheel 30 and the center gear 39, and rotates repeatedly in both directions in proportion and swings at a low speed, thereby completing the washing process. Figure 6 illustrate.

[0052] like Figure 9The transmission gear set 14 of the washing machine's deceleration clutch is a three-stage, double-linked external gear transmission mechanism. This mechanism consists of a center gear 6, upper double-linked planetary gears 323, lower double-linked planetary gears 322, a center gear 39, and a wheel carrier 7. The center gear 6 is connected to the input shaft 1. The lower teeth of the lower double-linked planetary gears 322 mesh with the center gear 6. The lower teeth of the upper double-linked planetary gears 323 mesh with the upper teeth of the lower double-linked planetary gears 322. The upper teeth of the upper double-linked planetary gears 323 mesh with the center gear 39. The center gear 39 is fixedly connected to the output shaft 2. There are two to three upper and three lower double-linked planetary gears 323 and 322, respectively. The lower double-linked planetary gears 322 are mounted on the wheel carrier 7, and the upper double-linked planetary gears 323 are mounted on the planetary shaft 311. The upper teeth of the upper double-linked planetary gears 323 are connected to the output shaft 2 via the center gear 39. A clutch device 400 is provided between the center gear 39 and the deceleration clutch case 3. A clutch device 400 is installed between the reduction gearbox 3 and the central gear 39. When the washing mode is in progress, the reduction gearbox 3 is fully braked, the wheel frame 7 is in a fixed axis state, and the drive motor drives the central wheel 6 and the lower double planetary gear 322 to rotate repeatedly in both directions. At the same time, the upper double planetary gear 323 and the central gear 39 drive the output shaft 2 to rotate repeatedly in both directions. The output shaft 2 rotates repeatedly in both directions in proportion and swings at a low speed to complete the washing process. The dehydration mode is the same as the attached diagram. Figure 6 illustrate.

[0053] like Figure 10 The transmission gear set 14 of the washing machine's deceleration clutch is a single-stage internal gear transmission mechanism. This mechanism consists of a center gear 6, lower planetary gears 310, a wheel carrier 7, and an internal gear 9. The lower planetary gears 310 are mounted on the wheel carrier 7. The internal gear 9 and the input shaft 1 mesh with the lower planetary gears 310, and the output shaft 2 is connected to the internal gear 9. The input shaft 1 is connected to the center gear 6. There can be two to six lower planetary gears 310. This washing machine deceleration clutch, which utilizes a dual-drive gear mechanism with a single-stage internal gear transmission, can be used with washing machines equipped with synchronous variable-frequency motors, with its speed set by the washing machine. A clutch device 400 is installed between the reduction gearbox 3 and the internal gear 9. During the washing operation, the reduction gearbox 3 is fully braked, and the wheel carrier 7 is in a fixed axis state. The drive motor, via the input shaft 1, drives the center gear 6, which in turn drives the output shaft 2 via the lower planetary gears 310 and the internal gear 9. The output shaft 2 rotates proportionally in both directions, oscillating at a low speed, completing the washing process. The dehydration operation is similar to the attached diagram. Figure 6 illustrate.

[0054] like Figure 11The transmission gear set 14 of the washing machine deceleration clutch is a single-stage external gear transmission mechanism. This mechanism consists of a center gear 6, lower planetary gears 310, planetary carrier 311, wheel carrier 7, center gear 39, and duplex planetary gears 321. The lower planetary gears 310 are mounted on wheel carrier 7, and the duplex planetary gears 321 are mounted on the planetary carrier 311. The center gear 6 meshes with the lower teeth of the duplex planetary gears 321 via the lower planetary gears 310. The upper teeth of the duplex planetary gears 321 mesh with the output shaft 2 via the center gear 39. The input shaft 1 is coaxial with the gearbox 3 and connected to the center gear 6. The number of lower planetary gears 310 can range from two to six. This washing machine deceleration clutch, featuring a dual-drive gear mechanism with a single-stage external gear transmission, can be used with washing machines equipped with synchronous variable-frequency motors. Its speed is set by the washing machine's electrical system. A clutch device 400 is installed between the reduction gearbox 3 and the center gear 39. When the washing mode is in progress, the reduction gearbox 3 is completely braked, the wheel frame 7 is in a fixed axis state, the driving motor drives the central wheel 6 to rotate via the input shaft 1, and the central wheel 6 drives the output shaft 2 to rotate via the lower planetary gear 310, the double planetary gear 321, and the central gear 9. The output shaft 2 rotates repeatedly in both directions in proportion and swings at a low speed to complete the washing process. The dehydration mode is the same as the attached Figure 6 illustrate.

[0055] like Figure 12 The transmission gear set 14 of the fully automatic reduction clutch is a two-stage, double-tooth inner planetary gear transmission mechanism; the mechanism consists of a center wheel 6, inner planetary gears 32 (2-6), planet carrier 311, triple planetary gears 331 (2-6) and wheel carrier 7; the inner planetary gear 32 is mounted on the wheel carrier 7, and the triple planetary gear 331 is mounted on the planet carrier 311; the input shaft 1 is connected to the center wheel 6 and meshes with the inner planetary gear 32. The upper, middle and lower teeth of the triple planetary gear 331 mesh with the center gear 39, the inner planetary gear 32 and the center wheel 6 respectively. A clutch device 400 is installed between the reduction gearbox 3 and the center gear 39. When the washing mode is in operation, the reduction gearbox 3 is fully braked, the wheel carrier 7 is in a fixed axis state, and the drive motor drives the center wheel 6 and the triple planetary gear 331 to rotate repeatedly in both directions. At the same time, the output shaft 2 is driven through the inner planetary gear 32, and rotates repeatedly in both directions in proportion and oscillates at a low speed, thereby completing the washing process. The dehydration mode is the same as the attached figure. Figure 6 illustrate.

[0056] like Figure 13The fully automatic reduction clutch's transmission gear set 14 is a small-tooth-difference planetary gear mechanism. This mechanism consists of an input shaft arm 317, two to six upper planetary gears 33, one to two lower planetary gears 310, an internal ring gear 9, and a wheel carrier 7. The input shaft 1 is connected to the input shaft arm 317. The upper planetary gears 33 are mounted on the wheel carrier 7 and mesh with the internal ring gear 9. The internal ring gear 9 is connected to the output shaft 2. The lower planetary gears 310 are mounted on the input shaft arm 317, with holes around them fitting on the wheel carrier 7 and meshing with the internal ring gear 9. Two lower planetary gears 310 are typically used, mounted opposite each other to reduce vibration. A clutch device 400 is installed between the reduction gearbox 3 and the internal ring gear 9. During the washing operation, the reduction gearbox 3 is completely braked, the wheel frame 7 is in a fixed axis state, and the drive motor 5 drives the input shaft arm 317 to rotate repeatedly in both directions, driving the lower planetary gear 310 to perform a planetary motion with only revolution but no rotation due to the constraint of the wheel frame 7, thereby driving the inner gear ring 9 to rotate, so that the output shaft 2 is driven to rotate repeatedly in both directions in proportion and swing at a low speed, thereby completing the washing process. The dehydration operation is the same as the attached Figure 6 illustrate.

[0057] like Figure 14 The transmission gear set 14 of the fully automatic reduction clutch is a cycloid pinwheel transmission mechanism; this mechanism consists of an input shaft arm 317, two to six upper planetary gears 33, one to two cycloid gears 319, an inner ring gear 9 (with a pinwheel 318 fixed to its lower portion), and a wheel carrier 7. The input shaft 1 is connected to the input shaft arm 317, the upper planetary gears 33 are mounted on the wheel carrier 7, the inner ring gear 9 is connected to the output shaft 2, and the cycloid gear 319 is mounted on the input shaft arm 317. The holes around the cycloid gear 319 are fitted into the wheel carrier 7 and mesh with the pinwheel 318. Two cycloid gears 319 are typically used, mounted opposite each other to reduce vibration. During the washing operation, the reduction gearbox 3 is completely braked, the wheel frame 7 is in a fixed axis state, and the driving motor drives the input shaft arm 317 to rotate repeatedly in both directions, driving the cycloid wheel 319 to perform a planetary motion with only revolution but no rotation due to the constraint of the wheel frame 7, thereby driving the pinwheel 318 and the inner ring gear 9 to rotate, and the output shaft 2 is driven by the inner ring gear 9 to rotate repeatedly in both directions in proportion and swing at a low speed, thereby completing the washing process. The dehydration operation is the same as the attached Figure 6 illustrate.

[0058] like Figure 15The dual-drive gear mechanism of the fully automatic reduction clutch is a transmission gear set 14, consisting of a center gear 6, two to six upper planetary gears 33, two to six lower planetary gears 310, an internal ring gear 9, and a wheel carrier 7. The input shaft 1 is connected to the center gear 6, and the upper and lower planetary gears 33 and 310 are mounted on their respective wheel carriers 7. The lower planetary gears 310 mesh with the center gear 6, and the upper and lower planetary gears 33 and 310 mesh with the internal ring gear 9 (a common gear). The internal ring gear 9 is connected to the output shaft 2. The two sets of wheel carriers 7 have different center distances, but can have the same shaft length and are connected to the same planetary carrier. A clutch device 400 is installed between the reduction gearbox 3 and the internal ring gear 9. When the washing process is in progress, the reduction gearbox 3 is completely braked, the wheel frame 7 is in a fixed axis state, the driving motor drives the center wheel 6 to rotate repeatedly in both directions, and through the upper and lower planetary gears 33, 310, and the inner ring gear 9, the output shaft 2 is driven to rotate repeatedly in both directions in proportion and swing at a low speed, thus completing the washing process. Figure 6 illustrate.

[0059] like Figure 16 The dual-drive gear mechanism of the fully automatic reduction clutch is a transmission gear set 14. This mechanism consists of a center gear 6, upper planetary gears 33 (2-6), lower planetary gears 310 (2-6), a duplex internal gear ring 9, and a wheel carrier 7. The input shaft 1 is connected to the center gear 6. The upper and lower planetary gears 33 and 310 are mounted on a common wheel carrier 7. The lower planetary gear 310 meshes with the center gear 6. The upper and lower planetary gears 33 and 310 respectively mesh with the upper and lower teeth of the duplex internal gear ring 9. The duplex internal gear ring 9 is connected to the output shaft 2. The wheel carrier 7 has the same center distance and is connected to the planetary carrier 5. A clutch device 400 is installed between the reduction gearbox 3 and the internal gear ring 9. During the washing operation, the reduction gearbox 3 is fully braked, the wheel carrier 7 is in a fixed axis state, and the drive motor drives the center gear 6 to rotate reciprocally in both directions. This, in turn, drives the output shaft 2 through the lower planetary gears 310 and the duplex internal gear ring 9, causing it to rotate reciprocally in both directions in a proportional manner, oscillating at a low speed, thus completing the washing cycle. Dehydration conditions are the same as in the appendix Figure 6 illustrate.

[0089] Example 4

[0090] like Figures 1 to 4 As shown, this embodiment introduces a washing machine, which includes an inner barrel 100, a protrusion for shifting the water flow is provided at the bottom of the inner barrel 100; and a deceleration clutch 200 as described in any one of the above embodiments one to three, wherein the output shaft 2 of the deceleration clutch 200 is connected to the inner barrel, and the input shaft 1 is connected to the driving motor 5 of the washing machine, and the power of the driving motor 5 is output to the inner barrel 1 in the form of an adjustable transmission ratio.

[0091] In this embodiment, the protrusion 101 provided on the bottom of the inner tub 100 can be a standalone impeller non-rotatably connected to the inner tub 100, or it can be an integrated impeller provided on the bottom of the inner tub 100 and having a curved surface with varying heights facing inward. This allows the washing machine to have only one power drive unit, the inner tub, so that the washing machine drive motor, through the aforementioned reduction clutch, outputs all power with an adjustable transmission ratio to the inner tub. The inner tub of the washing machine of the present invention eliminates the impeller that rotates relative to the inner tub. Instead, a protrusion protruding toward the interior of the inner tub is sealed, integrally formed, or fixedly packaged on the inner surface of the tub bottom. The rotation of the inner tub drives the water flow and the clothing along with it, achieving the purpose of washing and rinsing, avoiding the formation of a gap between the impeller and the inner tub bottom, and reducing dirt within the tub.

[0092] The washing machine in this embodiment can be any washing machine in the prior art that only needs to drive the inner barrel 100 to rotate independently, for example: a no-clean washing machine in which the inner barrel is a water container during the washing process, a self-cleaning washing machine with cleaning particles between the inner and outer barrels, a flocculation washing machine equipped with a flocculation treatment device for washing water for reuse, and the like.

[0093] In this embodiment, the deceleration clutch 200 and the drive motor 5 are installed together on the outer drum of the washing machine or the support, and the deceleration clutch 200 is coaxially arranged with the drive motor 5 and the inner drum 100 to ensure the smooth rotation of the inner drum 100.

[0094] In this embodiment, in order to enhance the connection strength between the output shaft 1 of the deceleration clutch and the bottom of the inner barrel and prevent the output shaft 1 from directly transmitting the rotational torque to the bottom of the inner barrel and causing deformation of the barrel bottom when rotating, a bracket is fixedly installed below the bottom of the inner barrel. Furthermore, in order to prevent water leakage caused by the direct installation of the bracket and the bottom of the inner barrel, the present invention changes the installation method of the bracket, cancels the fixing structure of the bracket and the bottom of the barrel, and designs the lower part of the inner barrel body to extend downward, and provides a circle of cylindrical extensions protruding from the lower surface of the barrel bottom. The bracket is fixedly connected to the cylindrical extension of the lower part of the barrel body through radially installed fixings, thereby fixing the bracket below the bottom of the barrel.

[0095] Of course, the present invention is not limited to the above examples. It is obvious to those skilled in the art that various modifications and changes can be made to the present invention within the scope of the claims of the present invention and their equivalents without departing from the spirit or scope of the present invention.
