Description

Technical Field

[0001] This utility model relates to the field of laundry equipment technology, specifically to a washing machine deceleration clutch device. Background Technology

[0002] A fully automatic pulsator washing machine, a commonly used household appliance, generally includes an outer tub, an inner tub inside the outer tub, and a pulsator inside the inner tub. The outer tub serves as the water tank, holding the wash water. The inner tub, acting as the spin-drying tub, is driven to rotate at high speed for spin-drying. The pulsator is driven to rotate in both directions within the inner tub, agitating the wash water to create a washing flow for washing clothes. The washing machine's reduction clutch, a core transmission component, primarily reduces the motor's speed and increases torque. It also switches between washing and spin-drying modes in the fully automatic pulsator washing machine.

[0003] In traditional washing machine deceleration clutches, when the washing machine is in the washing mode, the spin-drying shaft is braked, and the motor's bidirectional rotation decelerates the spin-drying shaft, causing it to reciprocate. The spin-drying shaft drives the impeller to reciprocate, while the inner tub of the washing machine does not rotate. Consequently, the clothes are not properly rubbed and washed, failing to achieve the desired washing effect and thus failing to improve the washing ratio of the washing machine.

[0004] In view of the above, this utility model patent is hereby proposed. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a washing machine deceleration clutch device that can achieve dual power output from the impeller shaft and the spin-drying shaft during washing, thereby driving the impeller and inner tub of the washing machine to operate with dual power, thus improving the washing ratio of the washing machine.

[0006] Specifically, the following technical solution was adopted:

The input shaft gear is fixed on the input shaft or is integrally formed with the input shaft. The input shaft gear meshes with the planetary gear train for transmission. The center gear is rotatably sleeved on the input shaft and meshes with the fixed-axis gear train for transmission. The planetary gear carrier of the planetary gear train is fixedly connected to the center gear.

[0011] The clutch shaft is sleeved on the input shaft, and one end is fixedly connected to the brake wheel;

[0012] The impeller shaft is fixedly connected to the planetary gear carrier of the planetary gear train;

[0013] The dehydration shaft is sleeved on the impeller shaft, and the internal gear ring is fixedly connected to the torque transmission disk. The dehydration shaft is fixedly connected to the torque transmission disk.

[0014] As an optional implementation of this embodiment, the torque transmission disk is provided with teeth on its outer periphery, and the torque transmission disk is fixedly connected to the internal gear ring through the teeth.

[0015] As an optional implementation of this embodiment, one end of the torque transmission disk is provided with insert teeth on its outer periphery, and the outer periphery edge of the other end extends beyond the tooth tip of the insert teeth to form a limiting end cap. The end of the inner gear ring has a limiting groove. The insert teeth of the torque transmission disk are inserted into the inner meshing tooth groove of the inner gear ring, and the limiting end cap of the torque transmission disk is in a limiting fit with the limiting groove.

[0016] As an optional implementation of this embodiment, a torque transmission disk spline hole is opened at the center of the torque transmission disk, and an external spline is provided at the end of the dehydration shaft. The external spline of the dehydration shaft is inserted into the torque transmission disk spline hole for fixed connection.

[0017] As an optional implementation of this embodiment, a wear-resistant ring is provided between the end of the planetary gear carrier of the planetary gear train and the end of the torque transmission disk near the planetary gear carrier.

[0018] As an optional implementation of this embodiment, a planetary gear carrier spline hole is formed at the center of the end of the planetary gear train, and an external spline is provided at the end of the impeller shaft. The external spline of the impeller shaft is inserted into the spline hole of the planetary gear carrier for fixed connection.

[0019] As an optional embodiment of this invention, the brake wheel includes a brake wheel body and a brake wheel cover. The brake wheel body has an open receiving chamber. The brake wheel cover is fixedly installed at the open end of the brake wheel body. The brake wheel cover and the brake wheel body enclose and form an installation chamber. The clutch shaft is integrally formed with the brake wheel cover.

[0020] A through-hole is provided on one end of the brake wheel body opposite to the open end. The impeller shaft and the dehydration shaft pass through the through-hole. A first rolling bearing is provided between the through-hole of the brake wheel body and the dehydration shaft.

[0021] As an optional embodiment of this invention, a washing machine deceleration clutch device of the present invention includes a lower housing, a brake wheel installed in the lower housing, a lower housing bearing seat, an input shaft and a clutch shaft passing through the lower housing bearing seat, and a second rolling bearing provided between the clutch shaft and the lower housing bearing seat.

[0022] As an optional implementation of this embodiment, a washing machine deceleration clutch device of this utility model includes an upper housing, the upper housing having an upper housing bearing seat, the impeller shaft and the spin-drying shaft passing through the upper housing bearing seat, and a third rolling bearing installed between the upper housing bearing seat and the spin-drying shaft.

[0023] As an optional implementation of this embodiment, a small water seal is provided between the impeller shaft and the dehydration shaft, and a large water seal is provided between the upper housing bearing seat and the dehydration shaft.

[0024] The working principle of the washing machine deceleration clutch device of this utility model is as follows:

[0025] During the washing cycle, when the brake wheel is in its initial braking state, the motor drives the input shaft to rotate. The input shaft drives the input shaft gear to rotate synchronously. The input shaft gear meshes with the planetary gear train, and the planetary gear carrier of the planetary gear train drives the central gear and the impeller shaft to rotate in the same direction. At the same time, the central gear drives the fixed-axis gear train, which drives the internal gear ring to rotate. The internal gear ring is fixedly connected to the spin-dry shaft, so it also drives the spin-dry shaft to rotate. The spin-dry shaft rotates in the opposite direction to the impeller shaft. At this time, the washing machine's deceleration clutch is in the washing state. This achieves the washing of laundry in a stable and ideal water flow, effectively improving the washing ratio of the washing machine.

[0026] During the dehydration process, the brake wheel is released, the clutch mechanism resets, and the input shaft gear engages with the clutch shaft via the clutch bushing. The clutch shaft and brake wheel are then fixedly connected to the dehydration shaft as a single unit. At this point, the entire mechanism, including the input shaft gear, clutch shaft, brake wheel, impeller shaft, and dehydration shaft, is integrated into a single unit. Driven by a motor, the entire mechanism rotates at high speed clockwise at the speed of the input shaft, achieving the dehydration operation.

[0027] This invention relates to a washing machine speed reduction clutch device. During washing, an input shaft, input shaft gear, planetary gear train, and impeller shaft form a speed reduction mechanism. The power output from the impeller shaft drives the impeller. The planetary gear train, consisting of the planetary gear carrier, central gear, fixed-axis gear train, internal gear ring, and spin-drying shaft, forms another speed reduction mechanism. The power output from the spin-drying shaft drives the inner tub. In this device, the brake wheel is fully braked. By directly driving the input shaft with the motor through a differential composite gear train speed reduction device, the output is reduced to two rotations with opposite directions and different speeds. This drives the impeller shaft and spin-drying shaft simultaneously, thereby driving the impeller and inner tub to rotate in opposite directions and at different speeds. This effectively rubs and washes the clothes, improving washing efficiency and increasing the cleaning ratio.

[0028] The dehydration shaft and the internal gear ring of this invention are connected by a torque transmission disc, which provides good rigidity, large transmission torque, and improves the stability of the dehydration process. Attached Figure Description

[0057] Example 2

[0058] See Figures 1-4 As shown, a washing machine deceleration clutch device according to this embodiment includes:

[0059] The brake wheel 3000 has an internal mounting chamber.

[0060] The reduction gear train is installed in the mounting cavity of the brake wheel 3000. The reduction gear train includes a planetary gear train 1700 located on the upper layer, a fixed-axis gear train 2900 located on the lower layer, and an internal gear ring 2800 that meshes with the planetary gear train 1700 and the fixed-axis gear train 2900 respectively.

[0064] The dehydration shaft 800 is sleeved on the impeller shaft 900 and fixedly connected to the internal gear ring 2800.

[0065] This embodiment provides a washing machine deceleration clutch device:

[0066] During the washing cycle, when the brake wheel 3000 is in its initial braking state, the motor drives the input shaft 100 to rotate. The input shaft drives the input shaft gear 1600 to rotate synchronously. The input shaft gear 1600 meshes with the planetary gear train 1700. The planetary gear carrier of the planetary gear train 1700 drives the central gear 1500 and the impeller shaft 900 to rotate in the same direction. At the same time, the central gear 1500 drives the fixed shaft gear train 2900, which in turn drives the internal gear ring 2800 to rotate. The internal gear ring 2800 is fixedly connected to the spin-drying shaft 800, so it also drives the spin-drying shaft 800 to rotate. The spin-drying shaft 800 rotates in the opposite direction to the impeller shaft 900. At this time, the washing machine's deceleration clutch is in the washing state. This achieves the washing of laundry in a stable and ideal water flow, effectively improving the washing ratio of the washing machine.

[0067] During the dehydration process, the brake wheel 3000 is released, the clutch mechanism resets, and the input shaft gear 1600 engages with the clutch shaft 1100. The clutch shaft 1100 and the brake wheel 3000 are then fixedly connected to the dehydration shaft 800. At this point, the entire mechanism, including the input shaft gear 1600, clutch shaft 1100, brake wheel 3000, impeller shaft 900, and dehydration shaft 800, is integrated into a single unit. Driven by the motor, the entire mechanism rotates at high speed clockwise at the speed of the input shaft 100, thus achieving the dehydration process.

[0068] In this embodiment, a washing machine speed reduction clutch device comprises an input shaft 100, an input shaft gear 1600, a planetary gear train 1700, and an impeller shaft 900 forming a speed reduction mechanism during washing. The power output of the impeller shaft 900 enables the impeller of the washing machine to rotate. The planetary gear train 1700, consisting of a planetary gear carrier, a central gear 1500, a fixed-axis gear train 2900, an internal gear ring 2800, and a spin-drying shaft 800, forms another speed reduction mechanism. The power output of the spin-drying shaft 800 enables the inner tub of the washing machine to rotate. In this embodiment, a washing machine deceleration clutch device is provided. The brake wheel 3000 is fully braked. The motor directly drives the input shaft 100 through a planetary gear train 1700 and a fixed-axis gear train 2900 in a composite gear train deceleration device with a fixed-differential speed. The output is reduced to two rotations with opposite directions and different speeds, so that the impeller shaft 900 and the spin-drying shaft 800 are driven simultaneously. This drives the washing machine impeller and the inner tub to rotate in opposite directions and at different speeds, thereby achieving the effect of rubbing and washing the clothes, improving washing efficiency and increasing the washing ratio of the clothes.

The central gear 1500 is rotatably sleeved on the second shaft segment 102, and one end abuts against the end of the first shaft segment 101.

[0070] This embodiment achieves the design of the input shaft gear 1600 and the rotatable installation of the center gear 1500 through the structural design of the input shaft 100.

[0071] Furthermore, in this embodiment, a first wear-resistant ring 3500 is provided between the end of the central gear 1500 and the end of the first shaft segment 101. In this way, when the central gear 1500 rotates on the second shaft segment 102 of the input shaft 100, its end contacts the first wear-resistant ring 3500, thus preventing wear.

[0072] In this embodiment, the input shaft 100 includes a third shaft segment 103 integrally formed with the second shaft segment 102. The third shaft segment 103 is located at one end of the second shaft segment 102 outside the mounting cavity of the brake wheel 3000, and the diameter of the third shaft segment 103 is smaller than the diameter of the second shaft segment 102. This design allows the center gear 1500 to be inserted into the second shaft segment 102 from one end of the third shaft segment 103 of the input shaft 100.

The ratchet and pawl clutch mechanism of this embodiment can realize the engagement and disengagement of the clutch bushing 1000 and the clutch shaft 1100. When the clutch bushing 1000 and the clutch shaft 1100 are disengaged, the machine switches to the washing mode; when the clutch bushing 1000 and the clutch shaft 1100 are engaged, the machine switches to the spin-drying mode.

[0075] As an optional implementation of this embodiment, the brake wheel 3000 in this embodiment includes a brake wheel body 3001 and a brake wheel cover 3002. The brake wheel body 3001 has an open receiving chamber, and the brake wheel cover 3002 is fixedly installed on the open end of the brake wheel body 3001. The brake wheel cover 3002 and the brake wheel body 3001 enclose and form an installation chamber. The fixed-axis wheel frame of the fixed-axis wheel system 2900 is fixedly installed on the brake wheel cover 3002, and the clutch shaft 1100 is integrally formed with the brake wheel cover 3002.

A fixed-axis gear 3100 is mounted on the fixed-axis wheel shaft 2902. A second wear-resistant ring 3600 is provided between the fixed-axis wheel carrier cover 2901 and the planetary gear carrier 2600 of the planetary gear train 1700.

[0077] In this embodiment, a washing machine deceleration clutch device is provided, wherein a plurality of fixed-axis wheel shafts 2902 are non-uniformly distributed along the circumference of the brake wheel cover 2901. Specifically, the center angle between at least two adjacent fixed-axis wheel shafts 2902 is different from the others. The fixed-axis gear train 2900 of this embodiment adopts a non-uniformly distributed gear train structure, which can increase the number of gears in the same space, improve the load-bearing capacity of the gear train, and has a compact structure and high space utilization. By using a non-uniformly distributed planetary gear train, more gears can be set, thereby improving the load capacity of the gear train.
