  • the invention relates to an automatic machine which is controlled by a program selector for washing articles, in particular non-ironing garments, by washing, rinsing and drying them whilst they are hanging up in a washing and drying chamber located inside the machine, which is provided at the top with tooth-like rods on which the garments can be hung as well as with sprinklers for the washing solution or water which is to be pumped around, and is supplied with circulating drying air in order to provide heat and dry up the moisture.
  • the washing, rinsing, finishing and drying of the garments in the hanging position which is characteristic of such machines ensures a mechanically gentle washing and general good care of the garments, which is of great practical importance particularly when washing non-ironing laundry. items which are sensitive to mechanical stress.
  • support rods arrayed like the teeth of a comb are fixedly arranged in the upper part of the washing and drying chamber of the machine so that, in order to introduce and remove the washing, the lid of the machine must be lifted up.
  • the spray tubes for the supply of soap solution and rinsing water are arranged only in the upperpart of the washing and drying chamber so that the laundry items which are hung up and are to be washed can be sprayed with suds-solution and rinsing water only from the top or from the outside.
  • the continuous, supply of suds solution leads to undesired reductions in the flow pressure of the solution since the foam which forms reduces the efficiency of the feed pump which circulates the liquid in an uncontrollable way.
  • the invention is concerned with improving and perfecting a washing machine of the general type mentioned above so that it is free of the aforesaid disadvantages, and is more economical to operate and easier to load while enabling more effective washing, rinsing, finishing and drying of the garments hanging in it.
  • This object is achieved in accordance with the present invention by mounting the support rods on a carriage which can be drawn out at the front of the machine, at least one additional spray tube being located in the lower part of the washing and drying chamber; the suds solution is recirculated intermittently, and the circulating drying air is made to pass from top to bottom through the washing and drying chamber.
  • Loading of the washing machine is substantially facilitated by the garment rods which are preferably hinged onto the movable carriage and able to be locked in an upwardly swung horizontal position, since the individual laundry items can be quite easily hung on and later removed from the rods of the carriage when the latter is pulled out at the front of the machine.
  • the spray tubes are arranged not only at the top but also at the bottom of the washing and drying chamber, preferably in the form of a spray arm rotating about its vertical central axis, the garments hanging on the rods can now be effectively flushed with suds solution and rinsing water both from the bottom and in between, whereby the washing and finishing effect is substantially improved. Also, despite the formation of foam through the intermittent pumping of the suds solution, a higher flow pressure of the suds can nevertheless be maintained at least periodically in the spray tubes. Furthermore a better drying effect is achieved by the passage of the circulating drying air through the washing and drying chamber 'from top to bottom in that the drying air is so to speak automatically distributed within the washing and drying chamber according to its temperature.
  • the relatively hot dry air flowing in at the top of the drying chamber tends to stay in the upper part of the chamber until it is cooled through absorption of the moisture in the garments and then sinks to the bottom.
  • turbulent chimney effects are avoided and the contact time with the drying air necessary for drying the garments is correspondingly reduced.
  • a narrow shaft for the circulated drying air which is supplied with cooling means and connected at the top and bottom with the washing and drying chamber.
  • a sprinkler may serve as the cooling means, preferably in the upper part of the air shaft, at about a third of the height from the top, so that the jets of the sprinkler are directed onto the outer wall of the air shaft.
  • the latter is has a wall lined with an absorbent mesh of textile material for the downwardly flowing cooling water whereby water particles are prevented frombeing carried along by the circulating air flowing past.
  • the circulating blower and the heating device for the circulating drying air which flows into the upper part of the washing and drying chamber are preferably arranged at the upper end of the air shaft.
  • the circulating pump is arranged in accordance with the invention to be driven intermittently, each rest period of the circulating pump being longer than its pumping time, preferably at least three to four times as long, and lasting for at least about 10 seconds.
  • the circulating pump (which is preferably driven by a pole-changing motor) should produce at the entrance to the individual spray pipes a minimum flow pressure of 0.5 atmosphere whereas for washing and rinsing sensitive fabrics, such as wool, as well as in certain rinsing stages of a normal wash, this minimum fluid pressure can be reduced to about two-thirds or one-half of the normal pres sure.
  • the invention also provides for an improved utilization of the electrical generated thermal energy with regard to the intermittent drive of the circulating pump.
  • This improvement is achieved in that heating of the suds solution is effected by two separately operable heating elements one of which is permanently switched on during the heating-up phase whereas the other, whose electric-power consumption preferably corresponds to that of that pump, is switched on only during the rest periods of the circulating pump.
  • the garments hanging on the rods are moved to and fro in an essentially horizontal direction at least during certain phases of the washing, rinsing and drying process.
  • the individual layers of the garments which hang in folds are thus opened up and rubbed together whereby the insides of the garments are at once more easily accessible to the suds solution, rinsing water, and drying air and are additionally subjected to further mechanical cleaning action, both of which factors lead to an improvement in the degree of uniformity of the wash and simultaneously reduce the processing time.

  • the rotating spray arm 7 is fed from below in the middle, as shown in FIG. 4.
  • Spraying of the laundry items from the top and bottom has proved advantageous particularly with cumbersome articles which during the washing and rinsing steps hang folded over the rods 2, because then the insides of the items which hang down in U- shaped folds can be sprayed directly.

  • the advantageous effect of the cooling water guiding fabric 224 is due in particular to the fact that the adhesive and capillary forces which keep the cooling water and condensate in the fabric are considerably greater than the separating forces for r the cooling water and condensate which are caused by the air flow.
  • a basic feature of appliances in which the laundry is washed and dried in the hanging state is that continuous spaces 226 remain between the articles from top to bottom (FIG. 14) through which the drying air can pass unimpeded and without absorbing the moisture from the wash.
