Description
Technical Field
The invention relates to the technical field of household appliances, in particular to a speed reducer and a washing machine adopting the speed reducer.
Background
When the traditional pulsator washing machine is in a washing state, the pulsator drives clothes and water in the pulsator washing machine to rotate directionally, and the purpose of washing the clothes is achieved in the process of directional rotation of the clothes and the water. In contrast, when the conventional pulsator washing machine is in a dehydration state, the inner tub drives the clothes in the pulsator washing machine to rotate directionally, so that the aim of spin-drying the clothes in the rotation process is fulfilled. Although the working mode of the conventional pulsator washing machine can basically meet the purposes of washing and spin-drying clothes, with the increasing requirements of users on the pulsator washing machine, the defects of the conventional pulsator washing machine in the process of washing and spin-drying clothes are also exposed, for example, when the pulsator washing machine washes the clothes, the pulsator drives the clothes to directionally rotate in a single direction, the effect of 'rubbing' the clothes cannot be achieved, the clothes which always rotate in a single direction are easily wound together, and the washing effect is very poor.
In order to solve the above problems, technicians often improve the operation modes of the pulsator and the inner tub to solve the problem of unidirectional rotation of the laundry, that is, when the pulsator washing machine washes the laundry, the driving force of the driving motor is transmitted to the pulsator and the inner tub through the decelerator of the pulsator washing machine, respectively, so that the pulsator and the inner tub rotate in opposite directions, thereby achieving the effect of "rubbing" the laundry and reducing the entanglement between the laundry. Although the pulsator washing machine with the structure basically solves the problems of the traditional pulsator washing machine, the pulsator washing machine still has some problems in the process of washing clothes, for example, the water flow is single, and the washing effect is poor; the operating frequency and the intensity increase of interior bucket can lead to the fault rate of reduction gear to increase, and reduction gear maintenance work degree of difficulty is big and cost of maintenance is high, leads to user's use to experience and worsens relatively.
Further, in order to reduce the failure rate of the reducer of the pulsator washing machine and increase the washing effect of the pulsator washing machine, a stirrer is provided in the pulsator washing machine by those skilled in the art. The stirrer is coaxially fixed with the impeller of the washing machine and rotates in the same direction at the same rotating speed, so that the stirring water flow in the washing machine is increased, and the washing effect of the impeller washing machine is improved. However, since the pulsator and the pulsator can be rotated at the same rotational speed in synchronization with each other, and cannot form multiple water streams advantageous for washing laundry, there is a need in the art for an apparatus that rotates the pulsator and the pulsator at different rotational speeds.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Fig. 1 is a schematic view of the principle of construction of a speed reducer 10 of the present invention.
As shown in fig. 1, according to one embodiment of the present invention, the speed reducer 10 includes a housing 102 and a gear train disposed within the housing 102, the gear train including a gear train housing 104. The gear train housing 104 is pivotally disposed within the housing 102 and is selectively rotatable relative to the housing 102. Further, the inner wall of the train wheel case 104 is provided with a first ring gear 106.
With continued reference to FIG. 1, the speed reducer 10 further includes an input shaft 108, a first output shaft 112, and a second output shaft 116, wherein the input shaft 108 is disposed on one side of the housing 102 and is connected to one end of a gear train.

Planetary assembly 114 includes sun gear 110, a carrier, a down-star 1144, and an up-star 1146, among others. The sun gear 110 and the input shaft 108 are coaxially fixed or integrally formed. A planet carrier (not shown) is fixed coaxially or integrally formed with the first output shaft 112, and the planet carrier is provided with a planet shaft 1142 at an end remote from the first output shaft 112.

Also, the clutch sleeve 128 can slide in the axial direction of the boss 124.
With continued reference to fig. 1 and 2, the reducer 10 further includes a braking member 130 and a coupling member 132, the braking member 130 is disposed to match with the clutch sleeve 128, for example, a positioning recess is disposed on the clutch sleeve 128, a positioning protrusion is disposed on the braking member 130, and the coupling between the braking member 130 and the clutch sleeve 128 is achieved by the cooperation of the positioning recess and the positioning protrusion.
As shown in fig. 1, the brake member 130 is fixedly attached to the housing 102, and when the clutch sleeve 128 slides upward, the brake member 130 engages the clutch sleeve 128, thereby securing the gear train housing 104 to the housing 102.
As shown in fig. 2, the connecting member 132 is disposed to match the clutch sleeve 128 and is fixedly connected to the input shaft 108, and when the clutch sleeve 128 slides downward, the connecting member 132 engages the clutch sleeve 128 to fix the train casing 104 to the input shaft 108, so that the train casing 104 and the input shaft 108 rotate synchronously.
Although not shown, the reducer 10 of the present invention further includes a driving mechanism including a clutch motor and a clutch spring coupled to the clutch sleeve 128, the clutch motor and the clutch spring driving the clutch sleeve 128 to perform a reciprocating sliding motion in an axial direction, thereby coupling the clutch sleeve 128 to the braking member 130 or the coupling member 132, and when the clutch sleeve 128 slides to the coupling member 132 and is coupled to the coupling member 132, the input shaft 108 rotates the sleeve 124, the train housing 104, and the third output shaft 126 in synchronization.
Fig. 3 is a schematic structural view of a pulsator washing machine 001 according to a preferred embodiment of the present invention.
Fig. 4 is a schematic structural diagram of an output shaft of the reducer 10 of the pulsator washing machine 001 shown in fig. 3.
As shown in fig. 3 and 4, according to a second aspect of the present invention, the present invention provides a washing machine 001, the washing machine 001 includes a driving motor, an inner tub 20, a pulsator 30, a pulsator 40, and the decelerator 10, wherein an input shaft 108 is connected to a power output end of the driving motor, a first output shaft 112 is coaxially fixed to the pulsator 30, a second output shaft 116 is coaxially fixed to the pulsator 40, and a third output shaft 126 is coaxially fixed to the inner tub 20.
Specifically, as shown in fig. 3 and 4, when the washing machine 001 is in a washing state, the driving motor of the washing machine 001 drives the input shaft 108 in the reducer 10 to rotate, and the input shaft 108 drives the pulsator 30 and the pulsator 40 to rotate in opposite directions through the gear train in the reducer 10, so as to drive the laundry and the water in the washing machine 001 to rotate in corresponding directions until the laundry washing operation is completed.
When the washing machine 001 is in a dewatering state, the driving motor of the washing machine 001 drives the input shaft 108 in the speed reducer 10 to rotate, and the input shaft 108 drives the inner tub 20 to rotate through the gear train shell 104 in the speed reducer 10, so as to drive the clothes in the washing machine 001 to rotate correspondingly until the clothes are dried.
For the convenience of describing the operation of the decelerator 10 according to the present invention, the operation of the decelerator 10 according to the present invention will be described below in conjunction with the washing state and the dehydrating state of the washing machine 001.
As shown in fig. 1 and 3, the clutch sleeve 128 is engaged with the brake member 130 in the washing state. Since the clutch sleeve 128 is connected to the sleeve 124 in a circumferentially fixed manner, the gear train housing 104 is stationary relative to the housing 102 of the gear unit 10. When the input shaft 108 rotates, the input shaft 108 drives the first output shaft 112 and the second output shaft 116 to rotate in opposite directions (as indicated by the arrows in fig. 1) through the gear train. Since the third output shaft 126 is fixedly connected to the train housing 104, the third output shaft 126 is relatively stationary. Finally, the pulsator 30 and the pulsator 40 perform a relative reverse rotation, and the inner tub 20 is stationary.
Fig. 2 is a schematic view illustrating the coupling effect of the clutch sleeve 128 and the coupling member 132 of the decelerator 10 shown in fig. 1.
As shown in fig. 2 and 3, in the dehydration state, the clutch sleeve 128 is disengaged from the brake member 130 and slides down into engagement with the coupling member 132. Since the clutch sleeve 128 is circumferentially fixed to the hub 124, the gear train housing 104 is circumferentially fixed to the input shaft 108. When the input shaft 108 rotates, the shaft sleeve 124 drives the third output shaft 126 to rotate synchronously through the gear train shell 104, and the rotating third output shaft 126 drives the inner tub 20 to rotate for dewatering the clothes. Further, during the synchronous rotation of the input shaft 108 and the train wheel housing 104, the first output shaft 112 and the second output shaft 116 can be driven to rotate in the same direction as the third output shaft 126 (as indicated by the direction of the arrow mark in fig. 2).
Fig. 5 is a schematic structural diagram of the agitator 40 of the pulsator washing machine 001 shown in fig. 3.
As shown in fig. 5, the washing machine 001 of the present invention further includes a pulsator 40, wherein the pulsator 40 is fixedly connected to the second output shaft 116 and is positioned between the pulsator 30 and the inner tub 20.
With continued reference to fig. 5, further, the pulsator 40 has a disc-shaped structure with radial protrusions 404 and circumferential grooves 402 on the upper surface, and the pulsator 40 is provided with meshes 406, so that water under the pulsator 40 passes through the meshes 406 upwards to impact the laundry in the washing machine 001 during the rotation of the pulsator 40, thereby enhancing the washing effect of the washing machine 001 on the laundry. In addition, the radial protrusion 404 provided on the upper surface of the agitator 40 can guide the water on the agitator 40 to flow in the circumferential direction, and the circumferential groove 402 provided on the upper surface of the agitator 40 can guide the water on the agitator 40 to flow in the radial direction in a centrifugal manner.
In summary, the decelerator 10 of the present invention can switch the washing machine between the washing state and the dehydrating state by switching the position of the clutch cover 128. When the washing machine is in a washing state, the pulsator 30 and the pulsator 40 can rotate in opposite directions according to a preset rotation speed ratio, improving the pulsator capability of the washing machine. When the washing machine is in a dehydrating state, the inner tub 20 is driven. Therefore, the reducer 10 of the present invention enables the pulsator 30 and the pulsator 40 to rotate in opposite directions according to a predetermined rotation speed ratio while ensuring the original functions of the pulsator washing machine, so that the water in the washing machine can form multiple swirling water flows, which can impact and flap the laundry in the washing machine better, thereby improving the washing effect of the washing machine.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
