Referring to fig. 1 to 8, the driving device in each embodiment includes a motor 7 and a transmission mechanism, an output shaft of the motor 7 is connected to an input member of the transmission mechanism, a first output member of the transmission mechanism is connected to the pulsator 18, and a second output member of the transmission mechanism is connected to a second end of the connection member 3. The clutch 6 is provided on one of the lower tub 5 and the pulsator 18, for selectively engaging the lower tub 5 and the pulsator 18. Specifically, in the following embodiments, the clutch 6 is disposed on the lower barrel 5 as an example, and the clutch 6 is a device capable of engaging and disengaging two components, such as an electromagnetic clutch, a friction disc clutch, etc., which are conventional in the art, and will not be described herein again since the related art and products are mature.
Example 1
The transmission mechanism of the pulsator 18 washing machine provided in this embodiment is a gear transmission mechanism, and the gear transmission mechanism in this embodiment includes an input gear 8, a transmission gear 9, and an output gear 11. Referring to fig. 1, the input gear 8 serves as both an input member and a first output member, that is, the input gear 8 is connected to the output shaft of the motor 7 and the rod-shaped connecting member extending from the pulsator 18, it should be noted that the connected input gear 8 is movably disposed on the axis where the output shaft of the motor 7 and the rod-shaped connecting member are located, so as to facilitate the separation of the input gear 8 from the transmission gear 9 to disconnect the transmission path between the input gear 8 and the output gear 11 in the spin-drying process at a later stage. The output gear 11 serves as a second output member, one end of the transmission gear 9 is engaged with the input gear 8, and the other end is engaged with the output gear 11, and the transmission gear 9 includes two gears, one large and one small, which are fixed to each other and coaxially disposed, for the purpose of transmission, and also the transmission ratio between the input gear 8 and the output gear 11 can be adjusted. It can be understood that, in order to realize synchronous transmission, the two gears of the transmission gear 9 may also have the same size, so as to realize the effect of the upper barrel 1 and the pulsator 18 rotating at different speeds in the same direction or rotating at the same speed in the same direction, and a proper transmission ratio is output by selecting proper gear parameters, such as modulus, major diameter and the like, so that the washing degree of the clothes in the upper half water body and the washing degree of the clothes in the lower half water body are kept consistent. During washing, the clutch 6 does not connect the lower barrel body 5 and the wave wheel 18, and the effect that the upper barrel body 1 and the wave wheel 18 rotate independently is achieved; during spin-drying, the clutch 6 acts to enable the lower barrel body 5 to be connected with the impeller 18, the input gear 8 moves along the axial direction to be separated from the transmission gear 9, and power is interrupted between the input gear 8 and the output gear 11, so that the aim of directly driving the impeller 18 and the lower barrel body 5 to synchronously rotate by the motor 7 is fulfilled, and the spin-drying function of the washing machine is fulfilled.
Example 2
In this embodiment, the transmission mechanism is a gear transmission mechanism, and the gear transmission mechanism includes an input gear 8, a transmission gear 9, a reversing gear 10, and an output gear 11. Referring to fig. 2, the input gear 8 serves as both an input member and a first output member, that is, the input gear 8 is connected to the output shaft of the motor 7 and the rod-shaped connecting member extending from the pulsator 18, it should be noted that the connected input gear 8 is movably disposed on the axis where the output shaft of the motor 7 and the rod-shaped connecting member are located, so as to facilitate the separation of the input gear 8 from the transmission gear 9 in the spin-drying process at a later stage to break the transmission path between the input gear 8 and the output gear 11. For example, the motor 7 outputs a clockwise driving force, and the power is transmitted to the pulsator 18 via the connection of the input gear 8 to rotate the pulsator 18 clockwise. The output gear 11 serves as a second output member, and the transmission gear 9 includes two fixedly connected gears, similarly to embodiment 1. One end of the transmission gear 9 is meshed with the input gear 8, the other end of the transmission gear is meshed with the reversing gear 10, and the reversing gear 10 is meshed with the output gear 11. By configuring proper gear parameters, the purpose of reverse independent rotation of the upper barrel body 1 and the impeller 18 can be realized, thereby realizing the hand rubbing function of the washing machine. The spin-drying process in this embodiment is the same as that in embodiment 1, and the lower tub 5 and the pulsator 18 are engaged by the clutch 6 to operate synchronously to achieve the spin-drying function of the washing machine.
Example 3
In this embodiment, the driving device further includes a first brake 15, and the first brake 15 mainly functions to brake the operating member. The transmission mechanism in this embodiment is a planetary gear mechanism including a sun gear 12, a planetary gear, a planet carrier 13, and a ring gear 14. Referring to fig. 3, the planet carrier 13 is selectively connected to the cabinet 16 of the washing machine through the first brake 15, i.e., the planet carrier 13 may be fixed with respect to the cabinet 16 or may rotate with respect to the cabinet 16 during operation. The first brake 15 for fixing the carrier 13 may be in various forms, such as limiting the movement of the carrier 13 by a shift lever, limiting the movement of the carrier 13 by a movable positioning pin, and so on. The sun gear 12 serves as both an input member and a first output member, the ring gear 14 serves as a second output member, and the ring gear 14 is connected with a second end of the connecting member 3. As shown in fig. 3, in the washing process, the first brake 15 fixedly connects the planet carrier 13 to the box 16, the motor 7 rotates clockwise to drive the sun gear 12 to rotate clockwise, and further drive the pulsator 18 to rotate clockwise, and under the reversing action of the pulsator, the gear ring 14 is driven to rotate counterclockwise, so that the purpose that the upper barrel body 1 and the pulsator 18 rotate in the opposite direction is achieved, the reverse scrubbing function of the washing machine is achieved, and the washing degree of clothes is improved. During spin-drying, the first brake 15 disengages the planet carrier 13 from the box 16, the planet carrier 13 can rotate freely, the planetary gear mechanism loses transmission efficiency, the clutch 6 connects the lower barrel 5 with the impeller 18, the effect of synchronous rotation of the lower barrel 5 and the impeller 18 is realized, and thus the spin-drying function is realized.
