Washing machine cleaning device, washing machine and cleaning control method thereof

Abstract

The invention discloses a washing machine cleaning device, a washing machine and a cleaning control method of the washing machine. The washing machine cleaning device comprises an outer barrel, an inner barrel arranged in the outer barrel and a driving shaft driving the inner barrel to rotate relative to the outer barrel. The water supply passage is arranged on the driving shaft, the spraying mechanism is arranged on the side wall of the inner barrel, and the water path communicating mechanism is used for communicating the spraying mechanism with the water supply passage; and the water outlet direction of the spraying mechanism faces the inner wall of the outer cylinder. The water supply channel is arranged on the driving shaft, no pipeline needs to be additionally arranged, and space is saved; more importantly, the water supply channel and the driving shaft rotate together, and the winding problem caused by additionally arranging a pipeline does not need to be considered; besides, cleaning water provided by the water supply channel reaches the spraying mechanism on the side wall of the inner barrel through the water channel communication mechanism, the spraying mechanism faces an interlayer of the inner barrel and the outer barrel of the washing machine and is close to the inner wall of the outer barrel, and the spraying effect is more direct and effective.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a washing machine cleaning device, a washing machine and a cleaning control method thereof. Background technique [0002] A washing machine generally includes a casing, an outer tub fixed in the casing, an inner tub disposed in the outer tub and rotatable relative to the outer tub, and a rotating shaft for driving the inner tub to rotate. With the increase of the number of washings, the washing machine will inevitably become "more dirty", that is, with the increase of the number of washings and the amount of laundry, various kinds of adhesion will adhere between the inner and outer drums, especially the inner wall of the outer drum. dirt. [0003] In the prior art, washing machines are mainly cleaned by spraying or brushing. However, the existing spray washing method is to spray water from the top of the washing machine to the interlayer between the inn...

AI Technical Summary

Problems solved by technology

However, the existing spray washing method is to spray water from the top of the washing machine to the interlayer of the inner and outer cylinders, and at the same time cooperate with the high-speed rotation of the inner cylinder to achieve the purpose of cleaning the inner and outer cylinders. Due to the problem of the position and orientation of the water spray, the existing The cleaning effect of the spray flushing method is not very good, especially the cleaning effect of the inner wall of the outer cylinder is not good.
