The intermittent circulation method of detergent liquid of centrifugal washing machine
The present invention relates to the novel washing machine manufacturing, refer in particular to patented New Cycle centrifuge washing formula washing machine technical field (the relevant patent No.: 97223228.1) of right of inventor.
In view of New Cycle centrifuge washing formula washing machine does not adopt intermittent circulation method of detergent liquid in design, and the relevant cleaning solution circulatory system is not provided with the intermittent cycle volume control device, when washing and cleaning procedure work, its circulating line is in normal open state, this just makes cleaning solution continue to circulate, certainly, clothing in its laundry dehydration barrel just is in normal wet condition naturally, this makes drive motors be in strong load operation state for a long time undoubtedly, powerful consumption causes the reduction of rotating speed and centrifugal force, can reach needed centrifugal force rotating speed though increase used power of motor greatly, increase the mechanical strength of transmission system and laundry dehydration barrel greatly, can reach designing requirement, but these can make undoubtedly the washing machine cost improve in a large number, and increase used electric energy and customer charge.
So purpose of the present invention just is to make clothing in laundry dehydration barrel and the bucket, when the washing cleaning procedure, constantly repeat to be in humidification, dehydration (little wet) state, avoid normal wet condition, solve the problem that the strong load of motor continuation brings preferably, and realize the acquisition of instantaneous maximum centrifugal force.
For ease of understanding and saving space, relevant washing machine structure explanation sees also the patent specification of New Cycle centrifuge washing formula washing machine.Mainly technical method of the present invention is described below: technical key point of the present invention is: the circular flow of controlling cleaning solution by certain hour at interval.The intermittent cycle flow control switch of pressing the certain hour spacing movement is set in the cleaning solution circulatory system (comprising pipeline) of washing machine, when washing and cleaning procedure, descending, ascending, perhaps simply open or close, alternately repeatedly control the circular flow of cleaning solution, make laundry dehydration barrel and clothes be in humidification repeatedly, dewatering state, type for independent use cleaning solution water circulating pump (being micro-electric water pump), also can be by the operation of control of pump motor, halted state realizes the intermittent cycle control of cleaning solution, make laundry dehydration barrel and clothes be in humidification repeatedly, dewatering state, realize the acquisition of maximum centrifugal force, reach purpose of the present invention.
Owing to adopt said method, need only be provided with one in centrifugal washing machine on its circulating line easily got final product by timer-operated electric flow switch by the certain hour spacing movement, for using electric water pump, electromagnetism power switch by the certain hour spacing movement also need only be set on its pump motor power circuit to get final product, which kind of type implements all to increase few cost (latter's cost is lower), and this just laundry dehydration barrel that makes is in humidification repeatedly, dehydration (little wet) state washing work, cleaning solution intermittent cycle method, just further perfect novel centrifugal washing machine.
In the embodiment accompanying drawing: 1. bucket (body) outside; 2. interior bucket; 3. middle pillar aqueduct; 4. water pump; 5. motor; 6. conical vertical injector; 7. water intaking valve; 8. dual-purpose valve is selected in draining, circulation; 9. vertical banded transparent water level observation window; 10. top cover; 11. water barrier; 12. pump intake; 13. water seal, transmission, braking mechanism; 14. brake lever; 15. brake driver; 16. pipeline fixed leg; 17. circulating line; 18. the circular clothing plate of pressing; 19. telescoping tube; 20. washing agent adds the ABC of; 21. water pump stauros framework; 22. electronic intermittent cyclic switch.
In the present embodiment, electronic intermittent cyclic switch (22) is arranged on the circulating line (17), and near water intaking valve (7) and draining, dual-purpose valve (8) position is selected in circulation, so that complete machine function control wiring, control principle is: after washing machine starts, water intaking valve (7) is opened into water, electronic intermittent cyclic switch (22) is in opening state at this moment, draining, circulation selects dual-purpose valve (8) to be in circulation position, the whole circulation pipe path, washing machine enters the into water and the even humidification that circulates smoothly, after inflow meets the washing water yield, water intaking valve (7) is closed, the controlled action of electronic intermittent cyclic switch (22) this moment changes closure into by opening, cleaning solution circulates to be supspended, laundry dehydration barrel and clothing be dehydration rapidly under powerful action of centrifugal force, pre-by the time if the detection of motor maximum speed, after reaching maximum centrifugal force effect requirement, electronic intermittent cyclic switch (22) is become open-minded by closure, cleaning solution circulates and temporary tract, laundry dehydration barrel and clothing are again by humidification gradually, so repeat, the clothes spot will be doing repeatedly, the wet condition transition process, under the effect of centrifugal force and cleaning solution chemical force, disintegrated in a short period of time, separate, break away from clothes, be dissolved in cleaning solution, reach the purpose of cleaning clothes, and further saved the time, water and electric energy.
