Abstract

The invention discloses a washing machine. A barrel is divided into an upper part and a lower part, the upper part is an outer barrel, and a clapboard is arranged between the upper part and the lower part of the barrel; an inner barrel is arranged on the upper part of the barrel, the inner wall of the inner barrel is provided with a rib plate which is spiral upwards and a hole, a rotating shaft is fixed at the central position of the bottom of the inner barrel, the lower end of the rotating shaft is connected with the upper end of a motor shaft which is extended out of the two ends of a motor, and a balance disc is arranged at the lower end of the motor shaft; and when the inner barrel of the washing machine rotates towards the same direction all the time, the spiral rib plate drives clothes to turn up and down, so that the aim of washing the clothes is fulfilled. During dehydration of the washing machine, the highest rotating speed of the motor is realized, and centrifugal force generated by the balance disc reaches the maximum value at the moment, so that unbalanced force generated by accumulating the clothes in the washing machine is eliminated, and resonance can be prevented from being generated by the unbalanced force caused by accumulating the clothes; and therefore, vibration elimination and reduction effects can be achieved.

Description

A kind of washing machine

Technical field

The present invention relates to a kind of washing machine, specifically a kind of washing machine taking abatement vibrating device.

Background technology

Vibration is the greatest drawback of laundry, especially low capacity 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, adopt cement block ballast in the bottom of washing machine, increase the deadweight of washing machine, to reach effectiveness in vibration suppression, but, carrying is inconvenient, and due to from great in handling process, expense is also large, and, this is that one forces oscillation damping method, and do not eliminate the source producing resonance, the effect of therefore 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 washing machine, this washing machine adopts centrifugal process balance, is eliminated in the rotating shaft of washing machine in the source of resonance, and resonance is not propagated to body, to reach the effect of the abatement source of resonant excitation.

The present invention solves the technical measures that its technical problem takes, the staving of washing machine makes upper and lower two parts, top is outer barrel, it is water cavity in outer barrel, the bottom of staving is power cavity, dividing plate is set between staving top and the bottom, opens axis hole in the center of dividing plate, bearing and water seal arrangement are installed in axis hole; In the staving of top, interior bucket is set, perforate on interior bucket surrounding wall body, make to communicate between interior outer barrel, the inwall of interior bucket arranges the gusset on screw, and the starting point of gusset is at the bottom of bucket, the terminal of gusset is on 2/3rds height of bucket wall, bottom of the barrel center fixed rotating shaft, rotating shaft through dividing plate, and presses dress bearing and water seal arrangement, the lower end of rotating shaft connects the upper end of two-way output shaft motor axle, and balancing frame is installed in the lower end of motor reel; The upper end of outer barrel of washing machine arranges cage, arranges lid and control panel box above cage, the automaton (prior art) of fitting machine washing machine in control panel box, and circumscripted power line connects automaton; Water inlet to be arranged on cage and to pass to the top of interior bucket, and delivery port is arranged on the bottom rear of outer barrel, and water inlet and delivery port are by its inflow of solenoid control and discharge time; In the corner, bottom of staving lower end, leg is set.During work, after putting into water in the interior outer barrel of washing machine, interior bucket starts to rotate, and rotates toward the direction all the time, clothing in bucket rotates thereupon, and along with spiral rib plate moves up, can drop down when clothing moves to gusset terminal at the middle part of interior bucket, then under the effect of current to sinking, when sink to bottom time again can gusset with moving up, go round and begin again like this, roll up and down, to reach the object of laundry.When entering dehydration procedure, the rotating speed of motor increases, and reach maximum speed gradually, the rotating speed of balancing frame also peaks simultaneously, at this moment the centrifugal force that balancing frame produces reaches maximum, piles up to overcome washing machine undergarment the out-of-balance force produced, and avoids clothing to pile up the resonance causing out-of-balance force to produce, thus reach by source of resonant excitation abatement in rotating shaft, thus reach the effect of the abatement source of resonant excitation.

Further, leg is made up of spring and heelpiece, and the upper end of spring connects at the bottom of bucket, and the lower end of spring connects heelpiece, and heelpiece adopts rubber to make.

Further, after putting into water in the interior outer barrel of washing machine, interior bucket starts to rotate, and rotates toward the direction all the time, clothing in bucket rotates thereupon, and along with spiral rib plate moves up, can drop down when clothing moves to gusset terminal at the middle part of interior bucket, then under the effect of current to sinking, when sink to bottom time again can gusset with moving up, go round and begin again like this, roll up and down

The invention has the beneficial effects as follows, not only cut down resonance, and avoid the noise that vibration produces, make washing machine smooth running, extend the life-span of washing machine, structure is simple.
