Description
The present invention relates to a kind of washing machine, particularly a kind of dehydration tube of washing machine or Water Extraction Machinery that utilizes carries out the washing machine that small amount is washed.
" openly specially permit the clear 59-11889 of communique " at Japan Patent, disclose a kind of washing machine in " openly speciallyying permit the clear 59-11890 of communique ".Its objective is the washing of carrying out small amount by the Water Extraction Machinery of washing machine, its structure is that the inner bottom part in dehydration barrel is equipped with an impeller, motor drives dehydration barrel and impeller by Water Extraction Machinery turn round to a direction together, and only allow the motor drives impeller of Water Extraction Machinery to turn round to other direction.Utilize dehydration barrel and impeller together to the running of direction, and only allow impeller, thereby in dehydration barrel, produce rotary water current and do washing to another direction running.In order to solve the problem that clothing twines in the laundry processes, this washing machine is untied the clothing except utilizing dehydration barrel and impeller to produce centrifugal current together when a direction turns round, also be provided with one by erectting the auxiliary body that pipe is formed, the problem that clothing twines when solving laundry with this on the base that has hole for water spraying and this base.
This washing machine is to utilize the dehydration barrel of little volume to replace the wash bucket of big volume to carry out the washing and the rinsing of small amount, the effect of saving water and energy is tangible, but in its structure, impeller can only rotate in one direction with respect to dehydration barrel, thereby twine when clothes washing, rinsing serious, cause the rate of cleaning low, wash uneven problem, can't reach the laundry effect of conventional washer, and may because of clothing twine serious, clothing skewness and influence next step dehydration work in dehydration barrel.
This washing machine is owing to be to put to running to one together by the motor drives dehydration barrel and the impeller of Water Extraction Machinery, and only allow impeller to do washing to another direction running formation eddy current separately, at this during to the running of two kinds of different directions, the dehydration tube axle is to realize (if employing is the dextrorotation spring by a spring one-way element with the combination of impeller axle with separating, when the impeller axle turns clockwise, connect with the dehydration tube axle by the spring one-way element, impeller and dehydration tube rotate together, when the impeller axle is rotated counterclockwise, the relative dehydration barrel axis of impeller axle does to surmount action, this moment, dehydration barrel was equivalent to wash bucket, must be fixing.) drive the rotation of impeller.Because the spring one-way element that is adopted, impeller can only rotate to a direction with respect to dehydration barrel, just can only realize the unidirectional running laundry of impeller, and this laundry mode clothing twines very serious, and it is low to clean rate, and it is inhomogeneous to do washing.In traditional washing machine, just just adopt this laundry mode washing big part clothing (for example sheet, blanket etc.).
This washing machine is that imagination adopts dehydration barrel and impeller to turn round to a direction, makes water and clothing guide barrel wall and portion on the upper side thereof under action of centrifugal force, thereby unties the clothing of winding.But in the centrifugal dehydrator, when the rotating speed of dehydration barrel reached 300 rev/mins, the water in the dehydration barrel will be thrown out under action of centrifugal force, and this phenomenon does not allow to occur in the dehydration barrel laundry processes.When therefore utilizing dehydration barrel to do washing, the rotating speed of dehydration barrel must be controlled at below 200 rev/mins, and the rated speed of the motor of general Water Extraction Machinery is about 400 rev/mins, if motor with traditional Water Extraction Machinery, the rotation of dehydration barrel can only be controlled at very short a period of time interior (about below 2 seconds) in motor start-up stage of Water Extraction Machinery during laundry, that is to say, when the water in the dehydration barrel has just produced the trend of edge bucket wall rising under action of centrifugal force, the motor of Water Extraction Machinery just must cut off the power supply, stop to drive dehydration barrel, otherwise the water in the dehydration barrel will be thrown at once out from the dewatering hole on dehydration barrel top.On the other hand, except in a flash in initial (or stop last) that start, because of producing between the inertia difference three of dehydration barrel, water, clothing outside the slight relative motion, basically the three is with identical rotational speed, can not produce the action of unclamping clothing, thereby in the whole washing process, having only impeller to rotate This move to a direction separately has laundry to use.
This washing machine is to adopt auxiliary body with the winding problem that solves clothing, but because the topped impeller of living of the base of auxiliary body has weakened the eddy current that impeller forms, therefore can only carry out so-called " soft laundry ", and laundry effect does not reach the effect of conventional washer certainly.
And the dehydration barrel of this washing machine and impeller are together when a direction running, brake block must leave brake drum, and impeller is separately when another direction running, in order to guarantee the running of the relative dehydration barrel of impeller, then brake block must compress brake drum, with fixing dehydration barrel, therefore when motor frequently commutates, the control system of the corresponding brake block of folding continually must be arranged.And the brakes of conventional dehydration machine is by dehydration barrel loam cake control, and the braking of uncapping is closed and covered then that brake block leaves brake drum, obviously is difficult to satisfy this operating mode.On the other hand, general Water Extraction Machinery is to adopt the single armed brake structure, the braking moment of a direction of this brake structure is big, and the braking moment of other direction is very little, brake dehydration barrel when therefore being difficult to guarantee the impeller individual operation effectively, dehydration barrel will be under the impact of water and clothing, and follows impeller under the drive of frictional force between dehydration barrel axis and the impeller axle and rotate, and has weakened the rotation of impeller with respect to dehydration barrel.Otherwise braking moment is little when then dewatering, and can not satisfy the requirement of brake hard in the dehydration.
The object of the invention is above-mentioned weak point of the prior art and a kind of bidirectional movement impeller that is provided with in the dehydration barrel of conventional washer or centrifugal dehydrator is provided, can carry out the small amount washing, the washing machine that good, the clean rate height of laundry effect, washing are evenly, the clothing winding is little, braking ability is good.
