Further, the pump case inside of draining pump is also provided with the filter for filtering soft flocks; Pump case outer setting is useful on the clean-up port of opening pump case and carrying out soft flocks cleaning, blanking cover also can be set, for the above-mentioned clean-up port of shutoff on clean-up port.
Present embodiment intermediate roll washing machine drainage method comprises the following steps:
Opening water discharge pump, uses first row water passage to discharge slurry;
Use second row water passage to discharge residual slurry after the draining of first row water passage;
Close draining pump, use the 3rd drainage channel to discharge residual slurry after first row water passage and the draining of second row water passage.
In the present embodiment, first row water passage and second row water passage are the draining of draining pump mode, and the 3rd drainage channel is manual mode draining.In course of action, the first valve is often opened, and the second valve, the 3rd valve are normally closed.Specific works flow process is:
Main draining: the first valve is communicated with, the second valve and the 3rd valve disconnect, draining pump carries out work, the water that washing machine urceolus is discharged axially flows into rotary blade region through water inlet pipe 20 along draining pump, after impeller action, outwards flow out along first row water passage along blade radial, then discharge through first row water tube hose;
Arrange residual water: after main draining finishes, in the time that user selects automatically to arrange residual water function key, the first valve disconnects, and starts to arrange residual water, arranges residual water and can be divided into two processes:
1) the second valve is communicated with, and the first valve and the 3rd valve disconnect, and draining pump works on, and starts auxiliary draining, and cannot arrange time, draining pump shuts down again, and the second valve disconnects;
2) the 3rd valve is communicated with, and the first valve and the second valve disconnect, and carries out manual mode and arranges residual water, and last residual water enters in the residual water box that is attached to pump case bottom, and user only need take out residual water box, and residual water is outwelled.
Adopt above-mentioned water discharge method, can be completely residual water be discharged to barrier part, ensureing does not have remaining sewage to retain, although also need user to participate, convenience and ease for operation improve before greatly, can further realize healthy washing.
Above are only a preferred embodiment of the present invention, second row water passage also can be set certainly in other embodiments or multiple second row water passages are set, also can realize drain function, meanwhile, the size of residual water box also can be adjusted as required.
Can be seen by above technical scheme, roller washing machine discharge structure of the present invention and method utilize first row water passage and second row water passage to carry out the draining of draining pump mode, utilize the 3rd drainage channel to carry out the residual water of lower drainage simultaneously, owing to having increased second row water passage, after draining on secondary, the residual residual water yield is very little, can directly come ground, can not cause what impact.Further, be provided with a residual water box in drain pump casing bottom, the free-end of described the 3rd water discharge outlet or described the 3rd drainpipe stretches into described residual water box, carry out the collection of residual water, due to after draining on secondary, the residual residual water yield is very little, and the residual water box of setting can additionally not increase the space of washing machine, very convenient residual water discharge and emptying.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the present invention.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
