It is introduced with the self-cleaning principle of cylinder filter element 10.
Firstly, dish-washing machine is intake by water inlet pipe 70 (see Fig. 8) when user washs tableware using dish-washing machine,
When inflow is enough, water inlet pipe 70 is closed, and washing pump is opened, and the water in water storage part 200 is extracted out and sent to washing the dishes by washing pump
The gushing arm component of machine is to wash the tableware in internal cavity of bowl washer 300.After washing pump is opened, the water flow in water storage part 200
It is flowed from a direction, cylinder filter element 10 rotates under the action of water flow, and the washing water in liner 300 enters cylinder filtering
Component 10, since cylinder filter element 10 is in rotation status during the work time, the residue on cylinder filter element 10
It will not assemble and reduce the filter area of cylinder filter element 10 in the same place.In washing water through 10 mistake of cylinder filter element
After filter, washing water back flows back into water storage part 200, is then washed pumping again and goes out and send to gushing arm component to follow to tableware
Washing-round is washed.
During cleaning, the residue of cylinder filter element 10 can be entered by the gully-hole 201 of 200 bottom of water storage part
In drainage pipeline 204.At this point, washing pump is still in working condition, but due to the setting of baffle 19, it can prevent washing pump will
More residue in drainage pipeline 204 is sucked out and influences cleaning effect.Simultaneously as baffle 19 possess enough intensity and
Thickness is smaller, and therefore, biggish granular residue is difficult the gap of the hole wall component in cylinder filter element 10 Yu gully-hole 201
It stops at 203 to block cylinder filter element 10.
When needing to clean cylinder filter element 10, cleaning pump 61 starts.Cleaning pump 61 will flow in water storage part 200
Cylinder filter element 10 is sprayed to carry out clearly to cylinder filter element 10 by the first guide part 621 after part water stream S out
It washes, while can also give the certain driving force of cylinder filter element 10 to drive cylinder filter element 10 to rotate.
When cleaning pump 61 is opened, water is directed to the hole of cylinder filter element 10 Yu gully-hole 201 by the second guide part 622
With to being pressurizeed at gap 203 to prevent residue from leaking out from drainage pipeline 204 at gap 203 between wall.
It should be noted that cleaning pump 61 can be opened in any working stage of dish-washing machine to realize to cylinder filter house
The self-cleaning of part 10.For example, dish-washing machine, which is generally comprised, washes and rinse three phases with prewashing, master, cleaning pump 61 can be at three
It opens in the course of work in any one stage in stage to be cleaned to cylinder filter element 10, rather than must wash the dishes
Machine could be opened after working.In this way, user does not need to be taken some time after completed washings to cylinder filter element
10 are cleaned, and user experience is improved.
In conclusion 200 bottom of water storage part of the household electrical appliance 1000 of embodiment of the present invention is formed with gully-hole 201,
Filtration system 100 includes the baffle 19 of cylinder filter element 10 and annular, and cylinder filter element 10 is rotatably arranged in water storage
In portion 200, the bottom of cylinder filter element 10 is at least partially situated in gully-hole 20, and baffle 19 is located at cylinder filter element 10
Bottom and gully-hole 201 hole wall between gap 203, baffle 19 partly blocks gap 203.
Bottom and the gully-hole of cylinder filter element 10 are located in the baffle 19 of the filtration system 100 of embodiment of the present invention
At the gap 203 of 201 hole wall.In this way, the setting of baffle 19 can preferably control cylinder filter element 10 and water storage part 200
Gap between bottom, anti-leak-stopping slag.Simultaneously as cylinder filter element 10 can be rotated, baffle 19 be also possible to prevent card slag with
It avoids that cylinder filter element 10 is caused to stall.
