Operation principle to the vibration absorber of tumbling-box washing machine of the present invention is illustrated below:
During washing machine work, described wash bucket 60 can produce vibration, and piston component 80 just carries out the reciprocating of above-below direction thereupon.
Below the oscillating rectilinear motion process of piston 86 is decomposed to come and introduce in detail: at first, vibration along with wash bucket 60, when described piston component 80 sharply moves down, with the compression of the air in the cylinder 70, the air pressure that is positioned at piston 86 the place aheads in the cylinder 70 is increased, and the resistance that the increase of air pressure makes piston 86 be subjected to increases; Simultaneously, with 92 compressions of the 2nd elastomeric element, the elastic force reaction piston 86 that the 2nd elastomeric element 92 produces, the resistance that piston 86 is subjected to further increases, thereby has hindered its downward motion widely.
At this moment, because the air pressure in piston 86 the place aheads is greater than cylinder air outside pressure, so the pressure-air in piston 86 the place aheads can be discharged cylinders 70 by the 2nd pore 76.
On the contrary, when piston 86 moves up under the effect of wash bucket 60 vibrations rapidly,, the air pressure that is positioned at piston 86 rears in the cylinder 70 is increased with the air compression of cylinder 70 inner carriers 86 back.The resistance that the increase of air pressure makes piston 86 be subjected to increases; Simultaneously, with 90 compressions of the 1st elastomeric element, the elastic force reaction piston 86 that the 1st elastomeric element 90 produces, the resistance that piston 86 is subjected to further increases, thereby has hindered its motion that makes progress widely.
At this moment, because the air pressure at piston 86 rears is greater than cylinder air outside pressure, so the pressure-air at piston 86 rears can be discharged cylinders 70 by the 1st pore 74.
Along with pressure-air is arranged to the outside of cylinder 70 by the 1st pore 74, described piston 86 can move up lentamente, thus the movement velocity that can slow down piston 86.
In sum, when piston component 80 carries out the reciprocating of above-below direction along with wash bucket 60 vibrations, the elastic force of cylinder 70 inner air pressures and the 1st, 2 elastomeric elements 90,92 can hinder its motion, makes it obtain buffering, thereby can reduce the vibration of wash bucket 60 effectively.
