Description
Technical field
The invention belongs to washing machine technology field, specifically, being related to a kind of valve plug equipped with liquid level sensor, further relate to
A kind of washing machine equipped with above-mentioned valve plug.
Background technology
The washing machine of the prior art needs to inject one to the interior bucket or outer barrel of washing machine during washing and rinsing
Quantitative water.Control for water injection rate generally uses two ways at present：One kind is that flowmeter is installed in inlet pipeline,
Liquid level in bucket is controlled by detecting flow of inlet water；Another kind is to install liquid level sensor in interior bucket or outer barrel, passes through detection
Liquid level inflow in bucket, to meet laundry requirement.For detecting the designing scheme of liquid level in bucket using liquid level sensor, greatly
All it is that liquid level sensor is mounted in the steel ladle for filling washings.
But currently in order to save water resource, for washing machine more and more by the way of holeless interior bucket, when washing, is interior
Without water between bucket, outer barrel, for anhydrous washing machine between this interior outer barrel, steel ladle is interior bucket, and in dehydration journey
Interior bucket also needs to rotate in sequence, can not just use existing a series of by water route/gas chamber/connecting pipe/pipe clamp/liquid level sensor etc.
The level detection mechanism that the combination of structure and component is formed draws detection liquid level from outer barrel, and if detection liquid level is needed from interior
Bucket draws corresponding signal piping, can not just realize interior outer barrel isolation truly, and existing this level sensing structure
More complicated, packaging technology is comparatively laborious, easily occurs in the leakage between signal piping and gas chamber and signal piping, sensor
Gas phenomenon, so as to influence the accuracy of detection.
Meanwhile easily the pilot port of level detection mechanism is made often containing dirts such as a large amount of silts, line bits in washings
Into blocking, so that level detection mechanism fails, level sensing can not be carried out, causes machine failure.
In view of this it is special to propose the present invention.
