Balance ring system on two planes for a spin rotary machine

Abstract

A textile washing machine has a rotary basket balanced in at least one of its two planes, where optionally a first balance ring is structurally formed at the lower part of the basket or bottom of basket in order to balance the lower plane of the rotary basket and/or optionally, a second balance ring structured at the upper part of the basket. The first balance ring comprises: a channel or track that forms an integral part with the bottom of basket, a viscous drag fluid lodged in the track, a plurality of spheres lodged in the channel or track, immerse in the viscous drag fluid, and a lid that seals hermetically against the track. The lid comprises at least one radial rib in order to provide the bottom of basket with a structural reinforcement so that the bottom of basket does not weaken due to the presence of the track or channel. The second balance ring includes: a base with a first wall and a second wall, a cover that closes the base and with the same walls of the base, a working fluid lodged in the base, at least a curved blade lodged in the base where the blade covers from the first wall of the base and leaves a clearing between the blade and second wall, allowing the working fluid to have a vertical component; and at least a straight blade lodged in the base and alternated with the at least one aforementioned curved blade.

Description

RELATED APPLICATIONS[0001]This application claims priority from Mexican application Serial No. MX / a / 2009 / 002329 filed Feb. 27, 2009, which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to washing machines, and more specifically, to washing machines that balance the load in a rotating centrifuge basket, where the balance system comprises balance rings in two planes.DESCRIPTION OF THE RELATED ART[0003]Any person who uses or has used a washing machine has had the opportunity to experience at times that the machine, when in spinning-dry (centrifuge) or in clothes dehydration process, produces extreme vibration, sometimes even making the machine move from its original place. This is known colloquially as “walking”. This occurs mainly because somehow the clothes and objects to be washed are not uniform, they have different shapes and their materials have different densities, and once the process of washing has finished and ha...

Benefits of technology

[0018]Besides placing the ring at the other extreme of the washing basket, another ring is placed integrally at the exterior face of the disk or bottom of the basket, a balance ring with spheres made preferably of steel, of which weight, size and amount have been carefully selected, helping to simplify their manufacture, reducing the number of parts required and hence making it less costly and more reliable. The spheres run submerged in a fluid that has a specific viscosity; the fluid's specific function is to slither the spheres in transitional state so that they don't slip within the track and they reach the position contrary to the imbalanced load in a quicker manner. This also helps to mitigate the noise generated by the spheres by not allowing them to get to a st

Problems solved by technology

And so, being the washing machines lighter, the vibration caused by imbalance becomes a major issue to deal with when considering the performance of the machine.
