In another embodiment of the present invention, the third gear 20 and the fourth gear 21 are coaxially connected to two ends of a central shaft 27, the middle of the central shaft 27 is rotatably connected to the sliding seat 23, specifically, the central shaft 27 is rotatably disposed on the top of the sliding seat 23 through a bearing, the bottom of the sliding seat 23 is slidably connected to the fixed plate 29, that is, the bottom of the sliding seat 23 is provided with a sliding structure, such as a sliding slot, a sliding rib or a roller, and the fixed plate 29 is provided with a structure matched with the sliding structure, such as a sliding rib and a sliding slot, or other sliding or rolling matching structures in the prior art; further, the fixing plate 29 is fixedly connected to the housing of the decelerator main body 17, the housing of the multi-function washing machine, or the base of the multi-function washing machine.

In still another embodiment of the present invention, when the sliding seat 23 is in the meshing position, the transmission ratio of the gear set formed by the first gear 18, the third gear 20, the fourth gear 21 and the second gear 19 is less than 1, that is, at this time, the first gear 18, the third gear 20, the fourth gear 21 and the second gear 19 form an accelerating gear set mechanism, so that the drum of the multifunctional washing machine can obtain a higher rotation speed instantly across the transient region, and at the same time, under the condition of not replacing the motor of the multifunctional washing machine, the accelerating gear set mechanism enables the drum to reach a higher rotation speed, so that the clothes in the drum can be dehydrated more thoroughly.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
