Abstract
The invention provides a washing method for washing machines, as well as a washing machine thereof. The washing method is characterized in that while a stirrer rotates during wash, a drainage pump pumps washing water out from a water storage bucket and jets the washing water upwards through a hollow stirrer shaft and a hollow core hole of the stirrer so as to lift washed clothes. During wash, as the drainage pump pumps the high-pressure water out from the hollow stirrer shaft and the hollow core hole of the stirrer so as to spray and lift the washed clothes, the washed clothes are effectively prevented from receiving the long-term wear of a stirrer vane, and the washed clothes are allowed to receive the wash and rinse of high-pressure water flow, the stir of the stirrer and the wash in various washing forms at the same time. The invention has the advantages of low wear, low intertwining, low noise, high cleaning rate, high washing efficiency and the like.
Description
Technical field
The present invention relates to a kind of washing methods of washing machine and use the washing machine of this method.
Background technology
The structure of conventional washer is to be made of parts such as housing, washtub, motor, control system and agitators.During washing, utilize washing clothes and washings in the positive and negative reciprocally agitator treating of the motor-driven agitator bucket to finish washing.Through practice and check, this washing methods has following deficiency:
1, clothing serious wear is cleaned ratio and detersive efficiency and is difficult to improve.
The agitator of rotation directlyly and singlely revolves and hits washing clothes at a high speed, and is big to the wearing and tearing of washing clothes.Particularly for a long time in the washing clothes amount, the washtub central authorities that washing clothes is very easily piled up above agitator form " feeling resentful " phenomenon and are difficult to upset, the washing clothes that is positioned at the washtub cavity of resorption can be sustained damage because of the friction of accepting agitator for a long time that is difficult to overturn again, also can make the washing clothes that is positioned at washtub central authorities be difficult to clean, cause detersive efficiency also not high because of the stirring that can't accept agitator and the rinsing of washings.
2, washing form is single, flow intensity weak, clothing easily produces winding.
What agitator carried out is a kind of single reciprocating motion, and it pulls out the current that swash is single vortex water flows, and single alr mode and single vortex water flow are limited to the washing force of washing clothes, and easily makes clothing produce winding.
Therefore, how resolving the technical problem that the wear rate of above-mentioned conventional washer, clean ratio, detersive efficiency and clothing easily twine the mutual contradiction of this group effectively, is that pendulum is at machine design person and the previous thorny and real technical barrier of producer's face.
Summary of the invention
The objective of the invention is to solve above-mentioned conventional washer the wear rate height, clean than and low, the easy winding of detersive efficiency, the washing form is single and flow intensity is weak deficiency and a kind of washing methods of washing machine is provided and uses the washing machine of this method.
In order to reach the purpose that solves the problems of the technologies described above, washing methods of the present invention is, during washing, in the time of the agitator running, draining pump pumps washings and upwards sprays, lifts substrate by the hollow core hole of hollow stirrer shaft and agitator from water butt.
Purpose of the present invention also provides a kind of full-automatic nested washing machine that adopts said method, it comprises housing, washing/dehydrating bucket, water butt, motor, arrangement of clutch, draining pump and agitator, it is characterized in that: the stirrer shaft of described agitator is that two ends are to logical quill shaft, stir the device central portion be provided with the lumen shaft of hollow stirrer shaft to logical hollow core hole, the end portion of hollow stirrer shaft is coaxial and can be connected with the water discharge outlet of described draining pump with the relative rotation, and the water inlet of draining pump is connected with the osculum of water butt.
Purpose of the present invention provides a kind of semi-automatic washing machine that adopts said method again, it comprises housing, washing/water butt, motor, draining pump and agitator, the stirrer shaft that it is characterized in that described agitator is that two ends are to logical quill shaft, the agitator central portion is provided with the interior axially hollow core hole to leading to hollow agitator axocoel, the end portion of hollow stirrer shaft is coaxial and can be connected with the water discharge outlet of described draining pump with the relative rotation, and the water inlet of draining pump is connected with the osculum of washing/water butt.
Draining pump running when described agitator turns round, draining pump did not turn round when agitator did not turn round.
The end portion of described hollow stirrer shaft spins by one of them water-guiding hole of two L-shaped hole water guide stands of water-sealed bearing and vertical section, another water-guiding hole of two hole water guide stands is connected with the water discharge outlet of draining pump by water pipe, is provided with sealing ring in the bottom of water-sealed bearing.
The water inlet of described draining pump is connected by the osculum of threeway with water butt or washing/water butt, first branched pipe of threeway wherein is connected with the water inlet of draining pump by water pipe, second branched pipe of threeway is connected by the osculum of water pipe with water butt or washing/water butt, the 3rd branched pipe of threeway is connected with the water inlet of drain solenoid valve by water pipe, and the delivery port of drain solenoid valve is connected with drainpipe.
Described agitator is provided with the convenient recess of installing by the external screw thread or the internal thread fixed installation of nut or hollow bolt and hollow stirrer shaft upper part at the top of nut or hollow bolt.
Described draining pump lift is 0.3-3.5m.
The power line of described draining pump is electrically connected with the washing gauge tap of washing machine.
Described agitator is an impeller, and the axle of impeller is that two ends are to logical hollow motor shaft or the quill shaft that links to each other with belt wheel integratedly.
The present invention compares with existing conventional washer has following technical advantage and good effect:
1, reduced the wear rate of clothing effectively.During washing, the strong pressure water that pumps from the hollow core hole of hollow stirrer shaft and agitator can be lifted washing clothes and leave the agitator of rotation at a high speed, thereby avoided the direct friction of washing clothes and mixing arm, directly reduced the wearing and tearing of agitator effectively clothing.
2, detersive efficiency and clean ratio have been improved effectively.During washing, from the hollow core hole of hollow stirrer shaft and agitator, pump strong pressure water and can effectively break up the washing clothes of piling up in bucket central authorities, make washing clothes be broken up and fully also accept equably when rolling the strong flushing of press water by press water, simultaneously, washing clothes is being accepted stirring and the rinsing of vortex water and the friction of washtub wall of agitator again; Multiple washing form combines and has just improved detersive efficiency effectively and cleaned ratio.
3, reduced the winding of clothing effectively.During washing, the direction of the vortex water flow that the strong pressure water that pumps from the hollow core hole of hollow stirrer shaft and agitator has produced when having dashed disorderly the agitator rotation makes washing clothes be difficult to produce kink and twine with vortex water flow.
4, alleviate the load of motor, reduced the noise of washing machine.The strong pressure water that pumps from hollow stirrer shaft and agitator hollow core hole sprays the clothing of weight on agitator, lift and leave after the agitator face, and agitator just can turn round like a cork, and the resistance of agitator is little, and the noise of motor is also just little naturally.
