Abstract

The invention discloses an absorber. A motor of a small-sized washing machine is changed into a motor with extending shafts at two ends; a shaft drum is fixed on the upper end of the lower end shaft of the motor; a centrifugal pan is connected to the periphery of the shaft drum; an upper water chamber, a lower water chamber and a water channel are arranged in the centrifugal pan; water is filled in the lower chamber; when the motor is in a static state or a spin-dry shaft rotates at low speed, the water in the water chamber stays in the lower water chamber; when the spin-dry shaft rotates at high speed, the water in the lower water chamber is all pushed to the upper water chamber, at the moment, the centrifugal force generated by the upper water chamber reaches the highest value, so that the unbalance force generated by clothes accumulation in the washing machine can be overcome; resonance is prevented from being produced by the unbalance force generated by the clothes accumulation; a resonance source disappears or is reduced in the rotating shaft, so as to achieve the aim of vibration attenuation.

Description

A kind of shock absorber

Technical field

The present invention relates to a kind of washing machine, specifically a kind of device of subduing vibration of washing machine.

Background technology,

vibration is the greatest drawback of laundry, especially mini small washing machine is because fuselage is little, from heavy and light, therefore vibration is large in laundry processes, particularly when dehydration, vibration is larger under the effect of uneven centrifugal force, tend to occur the fuselage phenomenon of " walking ", even can turn on one's side when serious, greatly shortened the service life of washing machine, some producers are in order to reduce the vibration of washing machine, the cement block ballast is adopted in bottom at washing machine, increase the deadweight of washing machine, to reach effectiveness in vibration suppression, but, in handling process due to from great, expense is also large, this is a kind of oscillation damping method that forces, do not eliminate the source that produces 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 shock absorber, this shock absorber adopts centrifugal process, and the source of resonance is eliminated in the rotating shaft of washing machine, makes resonance to body, not propagate, to reach good effectiveness in vibration suppression.

the present invention solves the technical measures that its technical problem takes, with a kind of small washing machine motor, change the two ends output shaft motor into, the upper shaft of motor is connected with the wash bucket axle, the lower end axle of motor is beam barrel fixedly, screw is opened in the bottom of beam barrel, be screwed into the locking screw nurse in screw, beam barrel is locked on axle, periphery at beam barrel connects centrifugal pan, centrifugal pan becomes collar plate shape, centrifugal pan is made hollow, be made as upper water cavity in hollow cavity, lower water cavity and water channel, the position of upper water cavity is higher than lower water cavity, lower water cavity is near the beam barrel surrounding, the up and down water cavity is logical by the water channel structure, hold full water in cavity of resorption, during inactive state or motor reel when low speed rotation, water in water cavity rests in lower water cavity, the resonance of at this moment motor reel generation is little, the centrifugal force that produces is also little, be not enough to water is got rid of in upper water cavity, cause resistance therefore can for electric motor starting and laundry, when the rotating speed of motor reel increases gradually, centrifugal force also strengthens, and the water in lower water cavity is pushed away gradually in upper water cavity, when the motor reel fast rotational, water in lower water cavity is all got rid of to upper water cavity, at this moment the centrifugal force that produces of upper water cavity reaches maximum, while to overcome washing machine, rotating, clothing is piled up the out-of-balance force that is produced, the out-of-balance force of avoiding the clothing accumulation to cause produces resonance, the source of resonant excitation is subdued in rotating shaft, resonance is passed to staving, thereby reach the purpose of vibration damping.

The invention has the beneficial effects as follows, not only subdued resonance, and the noise of having avoided vibration to produce, make the washing machine smooth running, extended the life-span of washing machine, simple in structure.

Description of drawings

Be described further the present invention is bright below in conjunction with accompanying drawing.

Accompanying drawing is a kind of structural representation of shock absorber;

In figure, 1. lower end axle, 2. beam barrel, 3. spiral shell nurse, 4. centrifugal pan, 5. upper water cavity, 6. descend water cavity, 7. water channel.

The specific embodiment

in the drawings, with a kind of small washing machine motor, change the two ends output shaft motor into, upper shaft at motor is connected with the wash bucket axle, the lower end axle 1 of motor is beam barrel 2 fixedly, screw is opened in the bottom of beam barrel, be screwed into locking screw nurse 3 in screw, periphery at beam barrel connects centrifugal pan 4, centrifugal pan becomes collar plate shape, centrifugal pan is made hollow, be made as upper water cavity 5 in hollow cavity, lower water cavity 6 and water channel 7, the position of upper water cavity is higher than lower water cavity, lower water cavity is near the beam barrel surrounding, the up and down water cavity is logical by water channel 7 structures, hold full water in cavity of resorption, when inactive state or motor reel when low speed rotation, water in water cavity rests in lower water cavity 6, the resonance of at this moment motor reel generation is little, the centrifugal force that produces is also little, be not enough to water is got rid of in upper water cavity 5, cause resistance therefore can for electric motor starting and laundry, when the rotating speed of motor reel increases gradually, centrifugal force also strengthens, and 6 water in lower water cavity is pushed away gradually in upper water cavity 5, when the motor reel fast rotational, water in lower water cavity is all got rid of to upper water cavity, at this moment the centrifugal force that produces of upper water cavity reaches maximum, while to overcome washing machine, rotating, clothing is piled up the out-of-balance force that is produced, the out-of-balance force of avoiding the clothing accumulation to cause produces resonance, the source of resonant excitation is subdued in rotating shaft.

Claims

1. shock absorber, with a kind of small washing machine motor, change the two ends output shaft motor into, it is characterized in that: the upper shaft of motor is connected with the wash bucket axle, the lower end axle of motor is beam barrel fixedly, screw is opened in the bottom of beam barrel, is screwed into the locking screw nurse in screw; Periphery at beam barrel connects centrifugal pan, and centrifugal pan becomes collar plate shape, and centrifugal pan is made hollow, is made as upper water cavity, lower water cavity and water channel in hollow cavity, and the position of upper water cavity is higher than lower water cavity, and the up and down water cavity is logical by the water channel structure; Hold full water in cavity of resorption.

2. a kind of shock absorber according to claim 1, it is characterized in that: described lower water cavity is near the beam barrel surrounding.

3. a kind of shock absorber according to claim 1, it is characterized in that: when inactive state or dry axle when low speed rotation, water in water cavity rests in lower water cavity, the resonance of at this moment motor reel generation is little, the centrifugal force that produces is also little, be not enough to water is pushed in upper water cavity, therefore can not cause resistance to motor starting, when the rotating speed of motor reel increases gradually, centrifugal force also strengthens, and the water in lower water cavity is pushed away gradually in upper water cavity, when the motor reel High Rotation Speed, the water in lower water cavity is all got rid of to upper water cavity.
