Pulsator washing machine and defoaming spraying device therefor

Abstract

The invention discloses a pulsator washing machine and a defoaming spraying device therefor. The pulsator washing machine comprises: an outer tub; an inner tub rotatably arranged at the outer tub; anda defoaming spraying device mounted on the inner tub and / or the outer tub and used for spraying a defoaming liquid between the outer tub and the inner tub and / or to the inner wall of the outer tub and / or the outer wall of the inner tub. The pulsator washing machine according to an embodiment of the invention allows foam between the inner tub and the outer tub to be eliminated and never to overflow from the outer tub, so that the pulsator washing machine is protected from being damaged.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a pulsator washing machine and an anti-foam spraying device for the pulsator washing machine. Background technique [0002] With the development of science and technology, the non-porous inner-tub pulsator washing machine has entered the public's field of vision. Compared with the traditional fully automatic pulsator washing machine, the non-porous inner-tub pulsator washing machine is in the washing process, the water is sealed in the inner tub, and there is no gap between the inner and outer tubs. water. [0003] However, in the non-porous inner tub pulsator washing machine in the related art, when draining water, the water in the inner tub enters the outer tub and is discharged through the drain pipe at the bottom of the outer tub. Since the water discharged into the outer tub by the inner tub is accompanied by a lot of detergent foam, especially in th...

Problems solved by technology

[0003] However, in the non-porous inner tub pulsator washing machine in the related art, when draining water, the water in the inner tub enters the outer tub and is discharged through the drain pipe at the bottom of the outer tub. Since the water discharged into the outer tub by the inner tub is accompanied by a lot of detergent foam, especially in the In the primary drainage stage, it is difficult for the foam to drain through the drain pipe with the water flow, so that it remains at the bottom of the outer barrel, and the outer barrel is relatively short because it does not need to hold water, so that when the foam height is high, it is easy to overflow from the top of the outer barrel. damage to washing machine
