Embodiment 1

[0048] Such as figure 1 As shown, a drum washing machine includes a body 100, an outer cylinder 200 and an inner cylinder 300 arranged in the body 100, and the outer cylinder 200 and the inner cylinder 300 are arranged coaxially. The outer cylinder 200 is fixed inside the machine body 100 , and the inner cylinder 300 is fixed on the drive shaft 400 and driven to rotate by the drive shaft 400 . Lifting ribs 330 are provided in the inner tube 300, which can lift the clothes in the inner tube 300 to a certain height, and then the clothes will fall down. After continuous lifting-dropping, the effect of beating is played, so as to achieve the cleaning effect on the clothes. In order to enhance the wetting effect of the clothes in the inner cylinder 300, a spraying and stirring device is also provided in the present invention, and the water is sprayed in the inner cylinder 300 through the spraying and stirring device, which can effectively improve the wetting effect of the clothes. ...

Abstract

The invention discloses a drum washing machine. The drum washing machine comprises an inner drum, a driving shaft which is a hollow shaft and drives the inner drum to rotate, and a spraying and stirring device arranged in the inner drum and provided with a spraying channel communicating with the driving shaft, wherein the spraying and stirring device is fixedly connected with the driving shaft, or the spraying and stirring device is rotatably connected relative to the driving shaft. According to the invention, the spraying and stirring device is flexible and diverse in connection form, multiple possibilities are provided for movement of the spraying and stirring device, the spraying requirement is met, more diverse water flow disturbance effects are provided, and the situation that the spraying and stirring device is wound by clothes due to insufficient driving force is avoided.

Description

technical field [0001] The invention belongs to the field of washing machines, in particular to a drum washing machine. Background technique [0002] The spray device of the existing drum washing machine is generally installed near the inner drum door, and the water splashed on the inner drum door during spraying blocks the user's observation of the washing status in the drum. [0003] The Chinese patent application number 201710901069.5 discloses a drum washing machine, comprising: an outer tub; an inner tub, the inner tub is rotatably arranged in the outer tub; a water supply device; an agitator, the agitator is arranged in the The inner cylinder is connected with the water supply device, and the agitator is driven to rotate by the water supplied by the water supply device. According to the drum washing machine of the embodiment of the present invention, by setting the agitator in the inner cylinder and using the water supply device to supply water to the agitator, the wa...
