Patented in the German Empire on April 12, 1913.

The present invention relates to a washing method and one suitable for practicing the same Contraption.

There are already known washing methods in which the before rinsing Dirt particles adhering to the laundry due to steam introduced into the laundry are dissolved, whereupon the latter partially escapes, partially as contaminated condensation water is derived. In contrast to this, according to the invention, a certain amount of water is alternately in vapor form and driven through the laundry in a liquid state, with the entire amount of steam partly in the laundry itself, partly converted into water by means of a suitable condenser becomes, which the latter runs back into the water tank to then leave behind the entrained dirt particles to be re-introduced as steam into the laundry.

The facility used to carry out this procedure is essentially based on the fact that the container intended for receiving the items to be washed has a device is provided, which is suitable for the entire amount of steam introduced into the laundry, if the latter has not already condensed in the laundry, convert it back into water, which then returns through holes provided in the bottom of the container is allowed into the water tank.

The arrangement of those used to introduce the steam is also new and peculiar Distribution pipes, which are grouped in a helical ascending manner around the main pipe are, so that the laundry is offered a helical support surface.

The device used to carry out the new washing process is shown in the drawing illustrated in one embodiment, namely shows:

Fig. Ι the device partly in view, partly in longitudinal section, while

Fig. 2 is a section along the line I-I of Fig. Ι and.

Fig. 3 is a view of the spirally arranged Manifolds as seen from the line H-II of Figure 1 shows.

In the figures, α represents an oven of a known type which is provided with a fire door and an ash pan and on which a steam generator b can be placed. A tube c, open at the top, opens into the side of the steam generator, in which the water column falls and rises according to the pressure prevailing in the steam generator.

The laundry container d , which is used to hold the laundry, is arranged above the steam generator b and is pressed tightly onto the container by means of a rubber ring e and screw connections f.

The container d is connected to the steam generator b by a centrally arranged pipe g and through some narrow openings h . Radial tubes i , which are provided with fine perforations k , are arranged around the tube g in the form of helical surfaces. A capacitor I is provided above the container d and is tightly connected to the former by means of a rubber ring m and suitable holding devices η.

The condenser can be used as a water condenser

Sator or the embodiment according to be designed as an air condenser. In the latter case, condenser tubes o, through which the steam from the room d into the

5 upper part of the condensation space can be provided, which pipes are surrounded by cold air, which flows in through one or more openings j> and after being heated by the condensation work out

ίο exits the pipe q . A safety valve r is provided in the usual way on the steam space.

The washing machine works as follows:

After loosening the screw connections and removing the condenser I , the objects to be washed are placed on the radial pipes i in such a way that they offer the largest possible surface area for the rising steam carrying soap foam. After the condenser I is placed tightly on the laundry container again, steam is generated by heating, which dissolves the dirt particles contained in the laundry when it penetrates and is then converted into water in the condenser. The condensed water runs through the laundry and takes the dirt particles that have already been loosened down with it into the water container, in which the dirt particles remain until the washing process is completed.

Due to the constant condensation of the vapors driven into the laundry, a continuous flow of steam is achieved without a sudden increase in voltage. Only after the capacitor itself has been heated to such an extent that sufficient condensation can not take place, the steam temperature rises above ioo °, namely is c by the arrangement of the funnel tube, and by appropriate dimensioning of the safety valve r ensured that one of the temperature of about 105 ° corresponding maximum voltage is reached.

If this voltage limit is exceeded, the safety valve r allows the steam to be blown off at a point in time at which the washing process is ended.

The technical advances achieved by the invention are based on the fact that the steam introduced into the laundry to dissolve the dirt particles in such an amount is condensed that on the one hand the amount of water required to rinse the laundry is formed and, on the other hand, the voltage despite the constant inflow of live steam only increases to the extent that the temperature of the condenser walls increases.

This has the advantage that the entire washing process with a relatively very small Amount of water and correspondingly small amount of soap can be carried out.

Another advantage of the method representing the invention is based on the fact that the constantly flowing fresh steam an intensive dissolution of the dirt is achieved, while the washing takes place only with the always pure condensation water, since the from the Dirt particles removed from the laundry remain in the water tank.

Another advantage of the invention is that at the end of the washing process an overheating of the steam to about 105 ° takes place, which is necessary for cleaning and the Disinfection of the laundry is of great importance.

Finally, it is emphasized as an advantage of the invention that by the very dome-shaped Arrangement of the distribution pipes provided with holes allows both a convenient introduction of the laundry as The vapors penetrating into the laundry are also exposed to a large area of attack.

Claims (3)

Patent Claims: 1. Washing method in which the steam after removing the dirt particles in the laundry has dissolved, is condensed, characterized in that the total amount of steam, if it has not already been well condensed in the wash go, converted into water by means of a suitable condenser is, which the latter runs back into the water tank to leave behind the dirt particles to be re-introduced into the laundry as steam. 2. Device for performing the method according to claim 1, characterized in that at the upper end of the container (d) receiving the laundry, a device (I ₁ 0, j>, q) for condensing the entire amount of steam introduced into the laundry, as long as the latter is not already condensed in the laundry, is provided, while the bottom of the container (d) is provided with holes (A) which allow the condensed water to return to the water container (b). 3. Apparatus according to claim 2, characterized in that the manifold pipes (i) arranged offset from one another in a known manner are arranged in a helically rising manner around a main pipe (g) for the purpose of providing the items to be washed with a helical support surface. 1 sheet of drawings.
