Washing machine

Abstract

A washer with upper and lower drain functions and working in stirring washing mode, centrifugal washing mode, or centrifugal dewatering mode features that the drain hole of water drum, the drain pump, lifgint tube, shunt chamber and lower drain pipe are sequentially connected, and the outlet of shunt chamber is connected to upper drain pipe. Its advantages are simple switching mechanism and low cost.

Description

technical field [0001] The invention relates to a washing machine, specifically, the invention relates to a washing machine with both upper and lower drainage functions, especially with three working modes of stirring wing washing, centrifugal washing and centrifugal dehydration fully automatic washing machine. Background technique [0002] The bucket of the washing machine or dehydrator of the prior art usually has drain holes at the bottom, and the washing machine or dehydrator of the lower drainage does not have a drainage pump, so the upper drainage cannot be done; Therefore, there is no drain valve. If you want to drain the water, you need to put the outlet of the drain pipe lower than the liquid level in the bucket. This will cause a siphon problem, and the liquid originally flowing in the drain pipe will be drained A stalled pump is also unable to stop the flow and thus loses control. Therefore, such an upper drainage washing machine cannot be used for lower drainag...

Problems solved by technology

[0002] The bucket of the washing machine or dehydrator of the prior art usually has drain holes at the bottom, and the washing machine or dehydrator of the lower drainage does not have a drainage pump, so the upper drainage cannot be done; Therefore, there is no drain valve. If you want to drain the water, you need to put the outlet of the drain pipe lower than the liquid level in the bucket. This will cause a siphon problem, and the liquid originally flowing in the drain pipe will be drained The pump stalls and fails to stop the flow, thus losing control

Therefore, such an upper drainage washing machine cannot be used for lower drainage

[0003] Another problem is that in recent years, there have been designs on pulsator-type washing machines to drive the washing and dehydration bucket to rotate when not draining to realize the centrifugal washing method, that is, to have three kinds of work of stirring wing washing, centrifugal washing and centrifugal dehydration at the same time. In order to realize the above working method, the fully automatic washing machine complicates the structure of the tractor or the drain valve, see ZL00247511.1 for details
