Description

Shock-absorbing washing machine motor lower support

Technical Field

The utility model belongs to the technical field of washing machines, and particularly relates to a lower support of a motor of a damping type washing machine.

Background

The washing process of the washing machine mainly draws dirt into water under the mechanical action of seepage, scouring and the like generated by machinery and the wetting and dispersing action of detergent to realize the purpose of cleaning. The washing liquid filled between the blades of the impeller is thrown to the barrel wall at high speed under the action of centrifugal force and rises along the barrel wall. At the center of the impeller, a low-pressure area is formed due to the throwing of the liquid, and the washing liquid flows back to the vicinity of the impeller. Thus, a vortex centered on the pulsator axis is formed near the pulsator. Under the action of vortex, the clothes rotate spirally, are thrown to the wall of the barrel after being sucked into the center and rub against the wall of the barrel. And because the center of the impeller is a low-pressure area, the clothes are easily sucked near the impeller and continuously rubbed with the impeller, and dirt is forced to be separated from the clothes like manually rubbing the clothes. Secondly, when the clothes are put into the washing liquid, due to inertia, the movement is slow, a speed difference exists between the water flow and the clothes, so that the water flow and the clothes generate relative movement, the water flow and the clothes generate relative friction, and the water flow scouring force also helps dirt to leave the clothes. Again, due to the irregular shape of the washing gush, when the spinning water flow hits the tub wall, its speed and direction change, creating turbulence. Under the action of turbulent flow, the clothes move irregularly and roll, fibers of the clothes are continuously bent and stretched by the twisted buttons, the clothes rub against each other, the effective washing area is increased, and the washing uniformity of the clothes is improved.

Washing machine during operation is thrown the clothing to the bucket wall through rotatory under the effect of centrifugal force at a high speed to rise along the bucket wall, in impeller center department, form the low-pressure area because of throwing away liquid, make the washing liquid flow back to near the impeller again, thereby the realization is to the washing of clothing, washing machine during operation drives the rotatory work operation of inner tube through electronic, however, can produce great vibrations in the current motor operation process, still can drive washing machine wholly when serious and shake, the use of giving washing machine brings not good experience and feels.
