Description

Bubble overflow prevention device and washing machine

Technical Field

The utility model relates to a washing machine part, especially an anti-overflow bubble device and washing machine.

Background

In the invention patent application CN112376214A, an outer tub of a washing machine is disclosed, comprising: the top of the barrel body is provided with an exhaust hole; a defoaming assembly disposed on the tub body; the defoaming assembly is provided with an exhaust channel, the inlet end of the exhaust channel is communicated with the exhaust hole, and the outlet end of the exhaust channel is communicated with the outside; a stopper disposed in the interior cavity of the vent passage for rupturing foam. Based on the design structure that the vent holes are positioned at the top of the outer barrel of the washing machine in the state that the outer barrel of the washing machine is assembled, when washing water is injected into the inner barrel assembled in the inner cavity of the outer barrel of the washing machine, the highest water level of the washing water has a longer distance relative to the vent holes, so that foam generated by the washing water is also far away from the vent holes, the foam generated by the washing water is reduced or avoided from the source and is discharged along the vent holes, and the problems of overflowing and overflowing are reduced or avoided. Meanwhile, even if foam is discharged from the vent hole, a blocking piece capable of breaking the foam is arranged in the vent channel communicated with the vent hole, and the long-path structure of the vent channel is combined to break the foam. And specifically discloses: the defoaming component firstly forms an exhaust channel 21 in the defoaming component, so that compared with a simple exhaust hole, the exhaust channel further forms a long path in the process of exhausting gas and foam, the long path can form a certain blocking effect in the process of exhausting the foam, and when the foam overflows in the long path formed by the exhaust channel 21, at least one part of the foam can be broken due to extrusion or friction with the inner wall of the exhaust channel 21, so that the direct overflow of the foam is avoided. When the two opposite blocking pieces 3 positioned on the opposite inner walls of the exhaust channel 21 form a matching relationship, a narrow gap can be formed between the two opposite blocking pieces 3 corresponding to the opposite positions in the exhaust channel 21, the gap not only can ensure that gas passes through, but also can effectively prevent foam from passing through, the narrow gap not only can effectively avoid foam from being discharged due to the extrusion on the foam, but also can effectively avoid the foam from being broken by the two opposite blocking pieces 3, and the foam overflowing preventing effect is good.

Because need lead to the structure of defoaming subassembly complicated through keeping off the piece to the breakage of foam, not only can increase the manufacturing difficulty and cost, the easy sanitary dead angle that forms between the lateral wall of the fender piece that the quantity is numerous and exhaust passage moreover, the liquid that produces after the foam breaks is remained easily in these sanitary dead angles, finally produces peculiar smell and mildenes and rot.
