Abstract
A damper is provided. A water tank is arranged on the bottom of a washing machine; the water tank is provided with a water inlet solenoid valve and a water pump; a washing barrel shaft is prolonged to extend into the water tank; the lower end of the washing barrel shaft is provided with a damper; due to the immersion of the damper in water of the water tank, resistance is produced for shakes of the damper by water, so an effect of force transmission to water by an impeller is formed; resistance to the shakes of the damper by water and centrifugal force produced during rotation of the damper are overlapped, so imbalanced force produced during dehydration of the washing machine can be overcome; and with load of gravity of stored water in the water tank, resonance cannot be transmitted to a barrel body. Water is stored in the water tank to cooperate actions of damping and loading actions of the damper and to be pumped by a water pump for re-use.
Description
Technical field
The present invention relates to a kind of washing machine, the device of specifically a kind of abatement vibration of washing machine.
Background technology
Vibration is the greatest drawback of laundry, especially mini small washing machine, because fuselage is little, from heavy and light, therefore in laundry processes, vibration is large, particularly when dewatering, vibrate larger under the effect of uneven centrifugal force, often occur that fuselage " is walked " phenomenon, even can turn on one's side time serious, substantially reduce the service life of washing machine, some producers are in order to reduce the vibration of washing machine, cement block ballast is adopted in the bottom of washing machine, increase the deadweight of washing machine, to reach effectiveness in vibration suppression, but, due to from great in handling process, delivery is inconvenient, expense is also large, and do not eliminate the source producing resonance, therefore the effect of weakening is also undesirable.
Summary of the invention
In order to make up the above-mentioned deficiency of washing machine, the invention provides a kind of vibration damping, this vibration damping adopts water balance centrifugal process, and utilize discharge water to carry out ballast, not only can cut down resonance, not propagate to body, the source of resonance is eliminated in the rotating shaft of washing machine, to reach good effectiveness in vibration suppression, and water saving.
The present invention solves the technical measures that its technical problem takes, in the bottom of washing machine, water tank is set, four angles that washing machine bottom is connected with water tank arrange cushion, described water tank establishes entering water electromagnetic valve and water pump, entering water electromagnetic valve is located at the top of water tank, this electromagnetic valve establishes an import and two outlets, import connects the outlet of washtub, in two outlets, one is suds outlet after laundry, run in outer tube, another is last one washings outlet, in access water tank, water pump is arranged on the top of water tank, run in water pipe, water pump is electronic or artificial, the effect of water pump is recycling of being released by the water in water tank, entering water electromagnetic valve and water pump are pulled (prior art) to control by chain of command, the upper planar central of described water tank opens axis hole, lengthen under the axial direction of washtub (dehydration barrel), the axis hole that this axle passes downwardly through water tank center stretches in water tank, shaft seal is made with soft waterproof material, close the gap between axle and axis hole, when avoiding washing, water tank is passed in the vibration of axle, avoids spattering outside water in cabinet simultaneously, vibration damping is installed in the lower end of described axle, axle sleeve established by vibration damping subcenter, the lower end of washtub axle is fixed on by axle sleeve, after this axle installs vibration damping, the position of vibration damping is just in time at the middle part of water tank, described vibration damping is made flat discoid, its diameter is less than the diameter of water tank, at the edge conjunction water fender of vibration damping, water fender one week around the edge of vibration damping, water fender and the sub-edge-perpendicular of vibration damping are installed, the height of water fender is greater than the thickness at the edge of vibration damping, 1/2 place of water fender height is connected on the edge of vibration damping, that is the first half of water fender grows the upper plane of vibration damping, the latter half of water fender grows the lower plane of vibration damping, vibration damping and water fender adopt lightweight hard material to make, to alleviate starting reactance during laundry.During washing machine work, the suds ejected are discharged from exclusive pipe by the entering water electromagnetic valve of water tank, when last one washings get off, controller meeting time delay several seconds, the suds remaining in pipe Inner are discharged from exclusive pipe, time delay is the outlet of entering water electromagnetic valve closedown suds after several seconds, open the import of water tank, washings enter in water tank, when water in wash bucket drains, dehydration starts, the entering water electromagnetic valve of water tank closes the import of water tank simultaneously, open suds outlet, the water taken off is made to discharge outside, described axle rotates in the water of water tank with vibration damping, along with the quickening of dehydrating speed, at this moment vibration damping will produce certain centrifugal force, and vibration damping is lightweight, and in water, because this reducing the starting reactance of motor, smooth and easy when making laundry and dehydration starting, when the rotating speed of axle is increased to peak value gradually, the centrifugal force of vibration damping also strengthens gradually, if when in dehydration, eccentric generation vibration piled up by clothing in bucket, the power of this vibration can pass to vibration damping by the axle disclosed that dewaters, vibration damping will rock, especially rock can be larger for the far-end of vibration damping, because vibration damping is under water, vibration damping is provided with water fender again, water can rock generation resistance to vibration damping, formed like paddle effect of Water transport power, to stop rocking of vibration damping, vibration is delivered in water by vibration damping simultaneously, again because water is by the disturbance of vibration damping, produce turbulent flow, therefore resonance can be cancelled out each other in turbulent flow, disappear in water, therefore, to the resistance that vibration damping rocks, water adds that vibration damping rotates the centrifugal force produced, these two power are superimposed, during to overcome laundry machine dehydration, clothing is eccentric piles up the out-of-balance force produced, avoid resonance, by source of resonant excitation abatement in rotating shaft, the gravity of adding institute's retaining in water tank carrys out ballast, resonance is not made to be transmitted to staving, thus reach the object of washing machine abatement vibration.
It is further water reuse, last one washings are that the last of washing crosses clear water, almost clean, and the water yield is large, existing washing machine just by these water in vain to having drained, very unfortunate, these water are except should not drinking, also recycling, the present invention stores these water in water tank, one has been coordinate the sub-weakening of vibration damping and ballast effect, two is be used in other side, release by set water pump and again utilize, as flushed the toilet, wash mop, water flowers, or return washing machine mixing liquid detergent, to wash hair one clothing, achieve useless water reuse, thus reach the object of water saving.
The invention has the beneficial effects as follows, not only cut down resonance, avoid the noise that vibration produces, make washing machine smooth running, and water saving, structure is simple.
