Abstract
A reciprocating washing machine comprising (i) reciprocating means capable of reciprocating movement; (ii) a wash vessel connected to the reciprocating means and capable of movement in co-ordination with the reciprocating means characterised in that the reciprocating means is provided with means for restricting the reciprocating movement to a predetermined number of degrees of freedom.
Description
Modified Machine Technical Field The invention relates to a washing machine suitable for washing articles using a system of at least two immiscible liquid phases. More particularly, the invention relates to a reciprocating washing machine that can be mounted either horizontally or vertically.
Background and Prior art Washing of fabric is generally carried out either by hand washing or by machine washing, using water in presence of a detergent.
Conventionally fabric is cleaned using water and a detergent surfactant system which is known as wet washing. Surfactants adsorb on both fabric and soil, thereby reducing the respective interfacial energies, facilitating removal of soil from the fabric.
Alternatively it is done by a process called dry cleaning where organic solvents such as perchloroethylene (PCE), petroleum based or Stoddard solvents, CFC-113 and .
1,1,1-trichloroethane are used, all of which are generally aided by a surfactant. The organic solvent helps in removal of oily soil in the presence of detergents.
Soil removal can be achieved by a small reduction in interfacial tension. The particulate soil is largely removed by providing agitation.
In our copending application (469/Mum/2000) it has been found that efficient removal of both soluble and insoluble soils may be achieved by the cleaning of fabric using the liquid-liquid interface of at least two immiscible liquid phases with an interfacial tension greater than 10mN/m, under agitation. It is also found that superior cleaning may be achieved economically by the use of water as a major component along with an organic solvent with the use of little or no surfactant. However, the cleaning performance of this liquid-liquid interface system in conventional washing machines could still be improved.

Conventional washing machines are almost always of a rotary type that may have the provision' for loading the fabric from the front or top whereby clothes and wash ftquor is rotated. These machines suffer from the disadvantage that this rotary action trmits the amount of mechanical action that can be provided. The front loading washing machines with a hor'~zontalty oriented drur~t clean utilising the tumbling action of the clothes. But this is unable to produce a high degree of mechanical action.
This mechanical action is even less with top loading machines with vertically oriented drums. To clean heavily soiled garments high mechanical action is essential.

1Q W09521954 discloses a washing machine wherein the wash vessel is.oscillated to introduce air bubbles into the wash liquor to improve the cleaning action of the washing machine. However, with this arrangement the shape and the movement of the washing vessel is restricted to the guide provided. The movement is essentially vertical and is dependent on the mass of the wash load and hnakes it necessary to have the mass uniform in order to achieve controlled reciprocation. The amplitude of motion is essentially frxed.1t is essential to have the balancing means for absorbing the unbalanced forces created by the motion. Since the reciprocation is on a vertical axis the system experiences differences in the upward and downward strokes. ft will be very dit~cutt to mount the machine horizontally and obtain the desired results.
The applicants have found that one or more of these disadvantages of rotary type and the known reciprocating type machines can be solved by the use of a reciprocating ..washing machine as descn'bed below. tt can be mounted either horizontally or vertically. The benefit of making it horizontal is that one does not need balancing means and shock absorbing mechanism which is essential if the wash vessel is moving up and down. By e~minating the guide for the wash vessel it is possible to have varied shapes of the washing vessel: In this machine the mass of the wash load is not a criteria for the motion and hence it can also be suitably varied.

(ii) a wash vessel connected to the reciprocating means and capable of movement in co-ordination with the reciprocating means characterised in that the reciprocating means is provided with means for restricting the reciprocating movement to a predetermined number of degrees of freedom. Preferably the reciprocating movement is linear. It is also desirable that the reciprocating movement is restricted to one degree of freedom. The washing machine preferably includes a frequency controller for controlling the frequency of the reciprocating movement to obtain the desired cleaning performance.
The washing machine according to one aspect of the invention comprises a prime mover which is a device capable of delivering a drive of the desired power and can be selected from any one of an electrical motor, induction motor, petrol engine or any other device known in the art. It is preferred that the prime mover is electrically operated and is provided with a frequency controller. The frequency control may be achieved by using an electrically or mechanically operated means.
According to a preferred embodiment the prime mover is connected to a frequency controller acting in conjunction with the means capable of converting the rotary movement into reciprocating movement.
The washing machine is preferably provided with means capable of converting rotary movement into the reciprocating movement comprising a crank (device) rotatably connected to a piston rod which is connected to the wash vessel. Thus according one embodiment, the prime mover is attached to means capable of converting rotary movement into a reciprocating movement comprising a crank with a rotatably installed connecting rod, which itself is connected to one end of a piston rod. The other end of the piston rod may be connected detachably to a wash vessel. Preferably, the piston rod is provided with means for restricting the reciprocal movement to a predetermined number of degrees of freedom. For example, guides such as bearings, plain guides, flat guides, dove tail guides etc. may be provided on the piston rod constraining and/or directing the movement of the piston rod in preferably one direction.
