It should be noted that, in the following embodiments 1 to 8, the description is based on the same inner tub assembly structure, which does not mean that the inner tub assembly of the present invention can be implemented only by the foregoing examples, and the specific embodiments are merely divided for convenience of illustrating the implementation of different driving devices.
Referring to fig. 1-8, the drive arrangement in each embodiment comprises a motor 7 and a transmission, the output shaft of the motor 7 being connected to the input member of the transmission, the first output member of the transmission being connected to the pulsator 18, and the second output member of the transmission being connected to the second end of the connecting member 3. A 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 tub 5, and the clutch 6 is a device that is conventional in the prior art and can achieve engagement and disengagement of two components, such as an electromagnetic clutch, a friction disc clutch, etc., and is not described herein because the related art and the product are mature.
Example 1
The transmission mechanism of the pulsator 18 washing machine provided by the embodiment is a gear transmission mechanism, and the gear transmission mechanism in the embodiment comprises an input gear 8, a transmission gear 9 and an output gear 11. Referring to fig. 1, the input gear 8 is used as both an input member and a first output member, that is, the input gear 8 is connected with the output shaft of the motor 7 and the rod-shaped connecting member extended 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 that detachment of the input gear 8 from the transmission gear 9 in a spin-drying process is conveniently achieved in a later period to disconnect the transmission path between the input gear 8 and the output gear 11. The output gear 11 serves as a second output member, one end of the transmission gear 9 is engaged with the input gear 8, 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 arranged, for transmission, and 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 can also have the same size, so that the effect that the upper barrel body 1 and the pulsator 18 rotate in the same direction and different speeds or rotate in the same direction and the same speed is realized, and proper transmission ratios are output by selecting proper gear parameters such as modulus, major diameter and the like, so that the washing degree of clothes in the upper half water body is kept consistent with that of clothes in the lower half water body. During washing, the clutch 6 is not connected with the lower barrel body 5 and the pulsator 18, so that the effect that the upper barrel body 1 and the pulsator 18 independently rotate is realized; during spin-drying, the clutch 6 acts to enable the lower barrel body 5 to be connected with the pulsator 18, the input gear 8 moves along the axial direction to be separated from the transmission gear 9, and power is interrupted to be transmitted between the input gear 8 and the output gear 11, so that the purpose that the pulsator 18 and the lower barrel body 5 are directly driven by the motor 7 to synchronously operate is achieved, and the spin-drying function of the washing machine is achieved.
Example 2
In this embodiment, the transmission mechanism is a gear transmission mechanism including 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 is used as both an input member and a first output member, that is, the input gear 8 is connected with the output shaft of the motor 7 and the rod-shaped connecting piece extended 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 piece are located, so that detachment of the input gear 8 from the transmission gear 9 in a spin-drying process is conveniently achieved in a later period to disconnect 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 by 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 transfer gear 9 is similar to that of embodiment 1, including two fixedly connected gears. One end of the transmission gear 9 is meshed with the input gear 8, the other end 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 aim of reversely and independently rotating the upper barrel body 1 and the pulsator 18 can be realized, and the hand rubbing function of the washing machine is realized. 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 coupled by the clutch 6 so that they are operated in synchronization 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 plays a role of braking the operating member. The transmission mechanism in this embodiment is a planetary gear mechanism including a sun gear 12, a planet gear, a carrier 13, and a ring gear 14. Referring to fig. 3, the planet carrier 13 is selectively connected to the housing 16 of the washing machine by a first brake 15, i.e. the planet carrier 13 may be fixed with respect to the housing 16 during operation, or may be rotatable with respect to the housing 16. The first stopper 15 for fixing the carrier 13 may take various forms, for example, restricting the movement of the carrier 13 by a lever, restricting the movement of the carrier 13 by a movable detent pin, or the like. The sun gear 12 serves as both the input member and the first output member, the ring gear 14 serves as the second output member, and the ring gear 14 is connected with the 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 then drive the pulsator 18 to rotate clockwise, and under the reversing action of the planet gears, the gear ring 14 is driven to rotate anticlockwise, so that the purpose of reversely rotating the upper barrel 1 and the pulsator 18 is achieved, and the reverse scrubbing function of the washing machine is achieved, so that the washing degree of clothes is improved.
