Embodiment
Embodiment of the present utility model is described below in detail, the example of embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the utility model, and it is not intended that to limit of the present utility model
System.
Common impeller or stirring type fully-automatic washing machine now, its drainage pattern mainly have upper draining (forced drainage) and
Lower two kinds of draining (gravity drainage).For upper draining (forced drainage) washing machine, its discharge pipe line it is general by installed in bucket bottom or
The pump of washing machine bottom, one section of connection extends upwardly to the drainpipe composition that height exceedes washing machine highest setting water level, washing
When, because the delivery port of drainpipe is higher, bucket washed water can be maintained in bucket；It is by the effect of pump, inner bucket water is strong during draining
System discharge.
Because steel ladle delivery port is less than bucket bottom, when drainpipe is submerged in water, one section of air can be lived in pipeline interior sealing,
Now continue draining or water inlet, in-pipe flow flowing because of the effect of external and internal pressure difference, can form negative pressure in pipeline, produce " rainbow
Inhale " phenomenon, occur while washing machine is intake while draining, causes washing machine cisco unity malfunction, and waste water.
The utility model is used to adjust the unidirectional of discharge pipe line air pressure inside by installing one additional at the top of discharge pipe line
Valve, it is simple and reliable the problem of solving washing machine drainage " siphon ".
The rotary drum washing machine 100 of the utility model embodiment is described in detail with reference to the accompanying drawings.
