Abstract:
The present invention belongs to the field of washing machines, and in particular provides a lifting device and a washing machine comprising the same. The present invention is intended to solve the problems that the existing washing machine is hard to move and that a moving device therefor is complicated in structure. The lifting device of the present invention comprises a cam, a first connecting rod, a second connecting rod, and a travelling wheel, wherein the centre of the base circle of the cam is coaxially fixed to an output shaft of a driving device, and an eccentric protruding shaft of the cam is pivotally connected to the first end of the second connecting rod; and the second end of the second connecting rod is pivotally connected to the first end of the first connecting rod, and the second end of the first connecting rod is pivotally connected to the travelling wheel. The driving device drives the cam to rotate, and the rotating cam drives the first end of the first connecting rod to rotate about a pivoting end by means of the second connecting rod, so that the second end of the first connecting rod drives the travelling wheel to move in the vertical direction, thereby raising or lowering the body of the washing machine. Therefore, the lifting device of the present invention can not only realise automatic lifting and moving of the washing machine, but also has a simple structure.
