Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The present invention proposes a kind of method of clearing up line bits filter, Fig. 1 gives the schematic diagram of cleaning line bits filter method, as shown in the figure, filter 1 comprises housing 11 and is installed on the filter screen 13 in housing 11, the partial impurities that filter 1 filters is hung on filter screen 12, by blowing in filter housings 11, thus disturbance being formed to the fluid of filter screen 13 region in filter, being hung on the impurity on filter screen 13 and can being separated with filter screen 13 under the disturbance of fluid and discharge filter 1.The method is applicable to the filter filtered fluid.
The method of this cleaning line bits filter is set forth below for washing machine filter.
Embodiment one:
Fig. 2 is the structural representation of the filter of application said method.As shown in the figure, this filter 1 comprises filter housings 11 and is installed on the filter screen 12 in housing 11.Described housing 11 offers water inlet 13, delivery port 14 and sewage draining exit 15, water inlet 13 is arranged at the top of described housing 11, described delivery port 14 is arranged at the middle part of described housing 11 perimembranous barrel, described sewage draining exit 15 is arranged at the bottom of described housing 11, filter housings 11 inner chamber is divided into inner volume and outside cavity volume two parts by described filter screen 12, inner volume upper end is connected with described water inlet 13, and lower end is connected with described sewage draining exit 15, and outside cavity volume connects with described delivery port 14.Sewage flows into inner volume from water inlet 13, and after filter screen 12 filters, enter outside cavity volume and flow out through described delivery port 14, the impurity of filtration is discharged by described sewage draining exit 15.Housing 11 lower end is provided with back taper changeover portion 17, and to connect described inner volume and described sewage draining exit 15, the setting of back taper changeover portion 17 can be conducive to the discharge of impurity.Back taper changeover portion 17 is symmetrical arranged two for connecting the inflatable mouth 16 of inflating pump 6.
Fig. 3 is the structural representation of the washing machine being provided with above-mentioned filter.As shown in the figure, this washing machine 8 comprises cylindric washer 2, draining pump 3, first valve 4 be connected with cylindric washer 2 bottom and the second valve 5, the outlet of described draining pump 3 is connected with above-mentioned filter 1, the outlet of draining pump 3 connects the water inlet 13 of filter 1, the delivery port of filter 1 is connected to cylindric washer 2 top by pipeline through the first valve 4, forms closed recirculation water pipeline; The sewage draining exit of filter 1 connects the discharge pipe line 9 of washing machine 8, discharge pipe line 9 is provided with the second valve 5.Two inflatable mouths 16 of filter 1 are connected by air blowing pipeline 7, and air blowing pipeline 7 connects inflating pump 6, are the refluence of anti-sealing, usually in pipeline, arrange check valve.
Fig. 4 gives the method flow diagram of this washing machine cleaning line bits filter, and as shown in the figure, the method is: washing and or after rinse stage starts, controller controls the filter operation that washing machine carries out recirculation water.The filter operation of recirculation water is specially, controller controls to open described draining pump and the first valve, second valve is in closed condition, slurry in cylindric washer is extracted out by draining pump, described slurry enters in filter through the water inlet of described filter and filters, described slurry after filtering flows out through the delivery port of described filter again, flows back in described cylindric washer through described first valve, and the impurity of filtration is stayed in described filter.
Washing and or after rinse stage terminates, controller controls washing machine and carries out lasting blowing operation, then carries out draining, blowdown operation.Lasting blowing operation is specially, controller controls to cut out draining pump and the first valve, and control inflating pump by blowing in gas blow pipe road direction filter, air-flow enters in filter screen by the bottom of strainer screen, thus disturbance is carried out to the water of filter screen region, because blowing direction is contrary with water (flow) direction, therefore rinse through current and be hung on disturbance that the impurity on filter screen is reversed and be separated with filter screen; Draining, blowdown operation are specially, controller controls opening water discharge pump and the second valve, first valve is in closed condition, slurry in cylindric washer is extracted out by draining pump, described slurry enters filter through the water inlet of described filter, slurry, together with the impurity stayed in described recirculation water filter operation process in filter, discharges washing machine through described sewage draining exit by described blow-off pipe.Also can carry out lasting blowing operation when carrying out draining, blowdown operation simultaneously, improving the cleaning performance of filter further.
Wherein, the setting position of inflatable mouth is not limited on back taper changeover portion, be arranged at the Lower Half of filter housings, quantity is also not limited to two, also can as shown in Figure 5, be arranged on the sidewall of housing, blow by inside the lateral of filter screen, form reverse turbulent water with the inflatable mouth be arranged on back taper changeover portion, what impurity and filter screen were departed from is more thorough.In order to increase bactericidal effect to filter, inflating pump can be replaced with ozone generator.
In addition, filter can act solely on the recirculation water pipeline of washing machine, carries out air-blowing cleaning line bits in the process of carrying out washing and or rinsing; Also on the discharge pipe line of independent role and washing machine, air-blowing cleaning line bits can be carried out in the process of carrying out draining.
Embodiment two:
The filter of the present embodiment and to have the washing machine structure of this filter all identical with embodiment one.Difference is, in the method for the cleaned filter of the present embodiment washing machine air-blowing, lasting blowing operation is replaced with batch (-type) blowing operation, intermittent aeration operation comprises flow-disturbing section alternately and interval section, in flow-disturbing section, inflating pump is blown in filter, thus forms lasting disturbance to the fluid of filter screen region; In interval section, inflating pump stops blowing to make the contamination precipitation be separated with filter screen.Like this, effectively can improving the service life of motor on the one hand, economize energy, on the other hand, when stopping the impurity coming off can being made to fall into filter bottom smoothly when blowing, facilitating the discharge of impurity.
Needing more supplementary: in the above-described embodiments, is all that the inflatable mouth by arranging specially is blown in filter housings, in the specific implementation, directly can also be blown to its inside by the sewage draining exit 15 of filter bottom, also can play same effect.
Below know-why of the present invention is described in conjunction with specific embodiments.These describe just in order to explain principle of the present invention, and can not be interpreted as limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present invention, and these modes all will fall within protection scope of the present invention.
