Definitions

• the fine mesh filter allows the incoming pressurised liquid and air to diffuse into the articles and produce a fast gaseous reaction inside the capsule due the liquid gaining heat energy by virtue of the liquid being forced through the plurality of tiny openings making up the filter mesh. It has been observed that this gives a sprinkler jet action for the gas- liquid mixture and yields excellent gaseous state cleaning particularly in the case of a washing machine where the liquid is water mixed with detergent.
• the preferred shape of the capsule ensures that articles and liquid are tumbled from one end to the other under gravity as the capsule is rotated. If it can be arranged that the air expands due to its being heated after coming into contact with the steam, a further increase in pressure within the capsule will result causing the detergent suds to more thoroughly permeate the articles particularly where the latter are formed from woven fabric, so further assisting the release of dirt and particles causing stains and marks in the fabric.
• the pump may be a centrifugal or positive displacement pump.
• a machine embodying the invention can give a superior wash and dry to the present class A wash and dry specification irrespective of load weight.
• a method is claimed for the use of a transparent dual rotating inner door connected to a stationary outer door, connected to a central member, for sealing against the cylindrical inner seal that is set inside the laundry loading aperture of the axial drive shaft of the capsule washing drum.
• a method is claimed for the use a single lower sieve type filter screen and an internal type conduit to draw the vacuum within a top loading capsule washing drum, the garments inside would always drop to the bottom of the capsule by gravity, due to suction the moment the vacuum cycle starts, this will always place the loading aperture to the top of the machine, in the vertical upright plane.

• Figure 19 is a schematic diagram of a pressure washing and vacuum drying machine.
• the latter includes three valves for controlling the admission of a water and detergent mixmre into the capsule, the extraction of fluid from the capsule and the delivery of fresh rinsing water to the capsule.
• one of the valves communicates with a pipe 114 leading from the outlet of a pump 116 (driven by a motor 118 having a motor control means 120), to which heated water and detergent are supplied via pipes 122, and solenoid valve 124 from a heating tank 126 containing an immersion heater 128 and supplied via solenoid valve 130 from pipe 132 from a detergent reservoir 132.
• Cold water is conveyed to the heating tank 126 via the solenoid valve 124 from pipe 134, itself connected to a cold water main 136 via solenoid valves 138 and 140.
• Pipe 139 is connected to a hot water main 141 via valve 142. Cold water can be conveyed to the detergent reservoir 132 by opening 140 and closing 138, to flush detergent via pipes 132 and valve 130 into the heating tank 126.
• hot water from 141 may be conveyed into and through the reservoir 132 by opening valve 142 and closing valves 138 and 140.
• the pump 116 can supply cold water at 175psi via pipes 144 to the 90 degree bend via bent pipe 146, from where it is exhausted via drain 148 to a sump 150.
• the latter includes an overflow 152 and a return pipe 154 which when valve 156 is open, provides a return for the water to the pump 116 from the venmri pump (not shown) formed in the 90 degree bend 158.
• pump 116 will produce a higher pressure.
• the rinse cycle may also be performed under positive pressure (ie above ambient) and the rinsing effect is seemingly enhanced by the partial vacuum created at the end of the rinse, by the action of the venturi pump 158.
