Washing machine damper structure with imbalance perceptive function

Abstract

The invention provides a laundry machine shock absorber structure with unbalanced feeling function, which comprises the following parts: cylinder in connection with one side of the laundry machine outer-tub; piston inserted in the cylinder with one side fixing the body case bottom; magnet set on the inner round surface of cylinder; magnet bushing set on the other inner round surface of piston; inductive electromotive force measuring device in connection with magnet bushing to measure inductive electromotive force of magnet bushing in the magnet motion course. The structure comprises the following advantages: stopping the washing and dehydrating operation after measuring the shock value because of shock caused by unbalanced washing articles; generating shock absorber force rapidly to reduce the shock and noise effectively according to the variation of shock values because the inductive electromotive force caused by shock absorber can reduce the shock; providing right and stable shock absorber force to reduce the shock without the relation of temperature variation of inner diameter or inside cylinder and operational time lasting of laundry machine.

Description

technical field [0001] The invention relates to a structure of a shock absorber, in particular to measuring the amount of vibration caused by the rotation of the drum when the drum washing machine is running, and sensing the unbalanced state of the laundry so that it can perform washing and dehydration in a stable state. Shock absorber structure for washing machine with balanced perception function. Background technique [0002] The washing machine is a device that uses the motor as the power source to remove the dirt on the clothes through the washing-rinsing-dehydration process and the action of detergent and water. The structure of the washing machine includes a motor that provides power, a mechanical part that transmits power to the laundry, a control part that adjusts the washing process, a water supply device that injects water, and a drainage device that discharges water. [0003] In addition, according to the washing method of the washing machine, it can be divided ...

AI Technical Summary

Problems solved by technology

[0013] As mentioned above, the existing general shock absorber cannot effectively adjust the shock absorbing force when the vibration amount changes because the shock absorbing force provided by the shock absorber does not change.

There is also no function that cannot stop washing or dehydration quickly when the inside of the shock absorber receives excessive vibration due to unbalanced washing

[0014] In addition, the existing general shock absorber does not have the function of quickly reducing the vibration amount by quickly reducing the vibration amount when a large amount of vibration is generated, and slowing down the shock absorption force when a small amount of vibration is generated.

[0015] In addition, due to damping by the frictional force generated between the inner wall of the cylinder and the frictional parts on the outer peripheral surface of the piston, serious frictional force deviations may occur depending on changes in the amount of lubricant, cylinder inner diameter, density of frictional parts, temperature, etc.

As the washing machine is used for a long time, the friction force is severely deviated, so that the washing machine cannot obtain a stable shock absorption force.
