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 a plurality of turbulent water streams, which are advantageous for washing laundry, cannot be formed, 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, the reducer 10 of the present invention mainly includes a housing 102, a gear train (not shown), an input shaft 110, a first output shaft 114, and a second output shaft 120. Wherein the gear train is disposed in the housing 102, and the input shaft 110 is disposed at one side of the housing 102 and connected with one end of the gear train. The first output shaft 114 and the second output shaft 120 are disposed on the other side of the housing 102 and are respectively connected to the other end of the gear train, and the second output shaft 120 is sleeved on the first output shaft 114. Also, the input shaft 110 is able to drive the first output shaft 1114 and the second output shaft 120 through the gear train to rotate in the same direction.
Specifically, as shown in fig. 1 and 2, the above-described gear train mainly includes a train wheel housing 104 and a first planetary gear assembly and a second planetary gear assembly provided in the train wheel housing 104. Wherein the gear train housing 104 is pivotably disposed within the housing 102 and can optionally rotate or be stationary relative to the housing 102. Further, the first planetary gear assembly is operatively connected to the second planetary gear assembly, as described in detail below.
With continued reference to fig. 1 and 2, the first planetary assembly basically includes the first ring gear 106, the first sun gear 112, the first carrier 118 and the first planet gears 119. The first ring gear 106 is disposed inside the gear train case 104, and the first ring gear 106 and the gear train case 104 may be fixedly connected or integrally formed. Further, the first sun gear 112 is coaxially fixed to or integrally formed with the input shaft 110. The upper end of the first carrier 118 in fig. 1 is coaxially fixed or integrally formed with the lower end of the first output shaft 114 in fig. 1. The first planetary gear 119 is pivotally provided on a lower end of the first carrier 118 in fig. 1, and engages with the first sun gear 112 and the first ring gear 106, respectively. As shown by arrows in fig. 1, the input shaft 110 can drive the first output shaft 114 to rotate through power transmission among the first sun gear 112, the first carrier 118, the first planet gear 119, and the first ring gear 106. Note that the directions of arrows in fig. 1 indicate the directions of rotation of the respective components in the speed reducer 10.
With further reference to fig. 1 and 2, the second planetary gear assembly mainly includes a second ring gear 108, a second sun gear 116, a second planet carrier 122, and second planet gears 123. The second ring gear 108 is disposed on the inner side of the gear train shell 104, and the second ring gear 108 and the gear train shell 104 may be fixedly connected or integrally formed. The second sun gear 116 is fixed coaxially or integrally formed with the first output shaft 114. The upper end of the second carrier 122 in fig. 1 is coaxially fixed to or integrally formed with the second output shaft 120. The second planet gears 123 are pivotally provided on the lower end of the second planet carrier 122 in fig. 1, and mesh with the second sun gear 116 and the second ring gear 108, respectively. As indicated by the arrows in fig. 1, the rotating first output shaft 114 can drive the second output shaft 120 to rotate in the same direction as the first output shaft 114 through power transmission among the second sun gear 116, the second carrier 122, the second planet gears 123 and the second ring gear 108. The direction of the arrows in fig. 1 indicate the direction of rotation of the components within the retarder 10.
Referring again to fig. 1 and 2, the reducer 10 of the present invention further includes a third output shaft 124 and a bushing 126. The shaft sleeve 126 is sleeved on the input shaft 110 and is fixedly connected with the lower end of the gear train shell 104 in fig. 1 or integrally formed. The third output shaft 124 is sleeved on the second output shaft 120 and is fixedly connected with the upper end of the gear train shell 104 in fig. 1 or integrally formed. Through the above-described connection structure, the third output shaft 124 and the boss 126 can be rotated synchronously.
With continued reference to fig. 1 and 2, the retarder 10 of the present invention further includes a clutch sleeve 128, a brake member 130 and a coupling member 132. The clutch sleeve 128 is sleeved outside the shaft sleeve 126 and is fixedly connected with the shaft sleeve 126 in the circumferential direction, that is, the clutch sleeve 128 cannot pivot around the shaft sleeve 126, and the clutch sleeve 128 can only rotate synchronously with the shaft sleeve 126 in the circumferential direction or can only be stationary synchronously with the shaft sleeve 126 in the circumferential direction. Further, the clutch sleeve 128 is axially slidably coupled to the bushing 126, i.e., the clutch sleeve 128 is vertically slidable on the bushing 126. The brake member 130 is disposed in mating relation with the clutch sleeve 128 and is fixedly attached or integrally formed to the housing 102. The coupling member 132 is coupled to the clutch sleeve 128 and is fixedly coupled to or integrally formed with the input shaft 110.
As shown in fig. 1, when the clutch sleeve 128 slides upward, the brake member 130 engages the clutch sleeve 128, and the train case 104 is fixed to the housing 102. In this state, the third output shaft 124 is fixed against rotation, and the first output shaft 114 and the second output shaft 120 can be driven by the input shaft 110 and rotate in the same direction at a set rotation speed ratio. The directions of rotation among the components of the input shaft 110, the first output shaft 114, the second output shaft 120, and the first and second planetary gear assemblies are shown by arrows in fig. 1.
It will be understood by those skilled in the art that the above-described rotation speed ratio can be calculated by the number of teeth of each of the first and second planetary gear assemblies and the revolution radius of the first and second planetary gears 119 and 123 around the respective sun gears. Those skilled in the art can set the number of teeth of each gear and the revolution radius of the planetary gears 119 and 123 around the respective sun gear according to actual needs.
As shown in fig. 2, when the clutch sleeve 128 slides downward, the connecting member 132 engages the clutch sleeve 128, thereby fixing the train housing 104 to the input shaft 110, causing the train housing 104 and the input shaft 110 to rotate synchronously, and thus causing the third output shaft 124 to rotate synchronously, in the direction of the arrow shown in fig. 2.
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, the washing machine 001 of the present invention includes a driving motor, an inner tub 20, a pulsator 30, a pulsator 40, and the decelerator 10 as described above. Wherein, the input shaft 110 of the decelerator 10 is connected with the power output end of the driving motor, the first output shaft 114 of the decelerator 10 is fixedly connected with the pulsator 30 of the washing machine 001, the second output shaft 120 of the decelerator 10 is fixedly connected with the pulsator 40, and the third output shaft 124 of the decelerator 10 is fixedly connected with the inner tub 20 of the washing machine 001.
Specifically, as shown in fig. 3 and 4, when the washing machine 001 is in the washing state, the clutch sleeve 128 is engaged with the brake member 130. The driving motor of the washing machine 001 drives the input shaft 110 of the reducer 10 to rotate, and the input shaft 110 drives the pulsator 30 and the pulsator 40 to rotate in the same direction through the first planetary gear assembly and the second planetary gear assembly in the reducer 10, so as to drive the laundry and the water in the washing machine 001 to rotate in the corresponding direction until the laundry washing operation is completed.
When the washing machine 001 is in the dehydration state, the clutch sleeve 128 is engaged with the connection member 132. The driving motor of the washing machine 001 drives the input shaft 110 in the speed reducer 10 to rotate, and the input shaft 110 drives the inner tub 20 to rotate through the shaft sleeve 126, the gear train shell 104 and the third output shaft 124, so as to drive the clothes in the washing machine 001 to rotate correspondingly until the clothes are dried.
For convenience of description of the operation principle of the decelerator 10 according to the present invention, the operation principle of the decelerator 10 according to the present invention will be described below through a washing state and a 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 126 in a circumferentially fixed manner, the gear system housing 104 is stationary relative to the housing 102 of the gear unit 10. When the input shaft 110 rotates, the input shaft 110 drives the first output shaft 114 via the first planetary gear assembly to rotate in the same direction as the input shaft 110 (as indicated by the direction of the arrow in FIG. 1). The rotating first output shaft 114 drives the second output shaft 120 through the second planetary gear assembly to rotate in the same direction as the input shaft 110 (as indicated by the direction of the arrow in fig. 1). Thereby achieving the purpose of co-rotating the first output shaft 114 and the second output shaft 120 (as shown by the direction marked by the arrow in fig. 1). In the process, the third output shaft 124 is relatively stationary because the third output shaft 124 is fixedly connected with the gear train shell 104. Finally, the pulsator 30 and the pulsator 40 rotate in the same direction according to a preset rotation speed ratio, 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 sleeve 126, the train casing 104 is circumferentially fixed to the input shaft 110. When the input shaft 110 rotates, the input shaft 110 drives the third output shaft 124 to rotate synchronously through the gear train shell 104 via the shaft sleeve 126, and the rotating third output shaft 124 drives the inner tub 20 to rotate, so as to achieve the purpose of dewatering the laundry. Further, during the synchronous rotation of the input shaft 110 and the gear train housing 104, the first output shaft 114 and the second output shaft 120 can be driven to rotate in the same direction as the third output shaft 124 (as shown in the direction indicated by the arrow 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 120 and is positioned between the pulsator 30 and the inner tub 20.
With continued reference to fig. 5, further, the agitator 40 is a disk-like structure having a radial protrusion 404 and a circumferential groove 402 on an upper surface thereof, and the agitator 40 is provided with a mesh 406. During the rotation of the pulsator 40, the water under the pulsator 40 can strike the laundry in the washing machine 001 upward through the mesh 406, thereby enhancing the washing effect of the washing machine 001. 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 the same direction 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 the same direction 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 turbulent swirling 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.
