Heizvorrichtung für WaschmaschinenHeating device for washing machines

Washer with this heater
Die Heuerung betrifft zunächst eine Heizvorrichtung für Waschmaschinen, insbesondere !Trommelwaschmaschinen. Solche Maschinen sind, soweit sie für den Gebrauch im Haushalt bestimmt sind, mit einer elektrischen Heizvorrichtung ausgerüstet, die zwar den Vorteil der Einfachheit hat, weil elektrischer Strom überall zur Verfügung steht, zumal er auch zum Antrieb der Waschmaschine gebraucht wird. Andererseits aber ist die Wärmeerzeugung aus Elektrizität ziemlich teuer - ein Bachteil, der bei dem in der Segel nur kurzzeitigen Sinsatz solcher Waschmaschinen im Haushalt in Kauf genommen werden kann.The hiring relates initially to a heating device for Washing machines, especially drum washing machines. Such machines are as far as they are for household use equipped with an electric heater, which has the advantage of simplicity because electricity is available everywhere, especially since it is is also used to drive the washing machine. On the other hand, the generation of heat from electricity is quite good expensive - a part of the stream that is acceptable when such washing machines are only used briefly in the household can be taken.

Hieß sind die Maschinen praktisch den ganzen lag über in Betrieb, und die Stromkosten für die Hei-But the situation is completely different with such washing machines can be used to paralyze a laundromat by continuously sending it to different customers for short periods of use be rented. The machines are said to have been in operation practically the whole time, and the electricity costs for the heating

Die !Teuerung besteht demzufolge zunächst darin, daß .--für Waschmaschinen der vorerwähnten Art eine an einem Snde mit Heizdampf beschickte, am anderen Ende offene Rohrschlange verwendet wird, welche Drosselstellen besitzt, die vorzugsweise regelbag sind und mit denen der Druck des in der Schlange strömenden Dampfes allmählich so weit herabgesetzt wird, dass er am Austrittsende etwa den Atmosphärendruck erreicht. Bei dieser Rohrschlange gibt der Dampf seine Wärme zunächst durch die Rohrwandungen an das Waschwasser ab} das dabei entstehende Kondensat wird unmittelbar in das Waschwasser entleert, und außerdem kann auch noch Dampf unmittelbar ins Waschwasser austreten. Auf diese Weise findet eine sehr rasche Aufwärmang des Waschwassers bei bestem Wärmewirtschaft--The! Increase in prices consists first of all in that - for washing machines of the type mentioned above, a pipe coil which is charged with heating steam at one end and which is open at the other end is used, which has throttling points, which are preferably Regelbag are and with those of the pressure of the queue flowing steam is gradually reduced so far that it reaches approximately atmospheric pressure at the outlet end. In this pipe coil, the steam first gives off its heat through the pipe walls to the washing water The resulting condensate is emptied directly into the washing water, and steam can also enter directly Wash water leak out. In this way it takes place very quickly Warming up of the washing water with the best heat economy -

Durch die eingebauten Drosselstellen wird erreicht, daß auch bei Verwendung von Hochdruck- .■ dampf am Austrittsende der Rohrschlange kein zu hoher Dampfdruck herrscht, sodaß der Dampf nur mit geringer Geschwindigkeit austritt.efficiency instead. The built-in throttling points ensure that even when using high-pressure. ■ Steam at the outlet end of the coil is not too high There is steam pressure, so that the steam only runs at low speed exit.
Um das starke Geräusch, das normalerweise beim Einleiten von Dampf in Wasser entsteht, noch weiter zu dämpfen, ist gemäß' einem weiteren Merkmal der Heuerung am Austrittsende der Bohrschlange eine das Rohr mit radialem Abstand umfassende Kappe angeordnet, deren Boden einen geringen Abstand vom offenen Rohrende hat und deren Wandung Dampfaustrittsöffnungen aufweist. . .-'About the loud noise that normally occurs when initiating of steam in water is to be further steamed According to a further feature of the hay at the exit end of the drill snake a pipe with a radial spacing arranged comprehensive cap, the bottom of which has a small distance from the open end of the pipe and the wall of which has steam outlet openings having. . .- '

In der Trommelwaschmaschine nach Fig. 1 befindet sich hinter einer durchsichtigen Klapptür 1o eine drehbare Waschtrommel 12. Sie ist von einem rohrförmigen Behälter 14- umgeben, der zu etwa 1/3 mit Wasser gefüllt ist und durch In the drum washing machine according to FIG. 1, a rotatable washing drum 12 is located behind a transparent hinged door 1o. It is surrounded by a tubular container 14, which is about 1/3 filled with water and is through

"- '. ge 18 arranged horizontally, by means of a built-in part 2o (Fig. 2) on the back of the washing machine is attached.
Die .Rohrschlange 2o besteht gemäß lig. 2 aus fünf parallelen Längsrohren 22 bis 3o. Durch zwei beiderseits geschlossene Querrohre 32, "34 mit eingeschweißten Böden 36 sind die Längsrohre so verbunden, daß der an dem Stutzen 37 eintretende Dampf sie in einem Zuge durchströmt. An den Rohrumkehrungen sind Schrauben 38 in die Querrohre 32 und 34 eingesetzt, die bis in die Längsrohre - hineinragen und den Strömungsquerschnitt verkleinern, also Drosselstellen bilden. ■-.The .Rohrschlange 2o consists according to lig. 2 out of five parallel Longitudinal tubes 22 to 3o. By means of two cross tubes 32, ″ 34 closed on both sides with welded-in bottoms 36, the Longitudinal pipes connected so that the steam entering at the nozzle 37 flows through them in one go. At the pipe inversions are screws 38 inserted into the cross tubes 32 and 34, which protrude into the longitudinal tubes - and the flow cross-section reduce, so form throttling points. ■ -.
Das offene Austrittsende des Längsrohres 3o weist ein Rohrstück 4o auf, welches geringeren"Durchmesser hat als das Eohr 3o. Ss ist von einer Kappe 42 mit radialem Abstand umfaßt und endet mit geringem Abstand von dem Boden 44 der Kappe 42, sodaß sich an dieser Stelle eine weitere Drosselung des Dampfstromes ergibt. Die Wandung der Kappe 42 ist mit Schlitzen 46 versehen,.aus denen das Kondensat und der Dampf unmittelbar in das Waschwasser austreten kann« "-.---^The open discharge end of the longitudinal tube 3o comprises a tubular piece to 4o, which lower "diameter h a t as the EOHR 3o. Ss is comprised of a cap 42 at a radial distance and terminates at a small distance from the bottom 44 of the cap 42, so that at This point results in a further throttling of the steam flow. The wall of the cap 42 is provided with slots 46, from which the condensate and the steam can exit directly into the washing water
Der Kappenboden 44 weist eine mittige Bohrung 48 auf, die in eine zweite Kappe 50 mündet, welche auf die Außenseite des Bodens 44 aufgeschweißt ist und deren Wandung mit Austrittsöffnungen 52 versehen ist. The cap base 44 has a central bore 48 which opens into a second cap 50, which is on the outside of the bottom 44 is welded on and the wall of which is provided with outlet openings 52.

Durch die vielfache Drosselung des strömenden Dampfes durch die Schrauben 38, ferner am Boden der Kappe 42, an den Schlitzen 46, der Bohrung 48 und den Austrittsöffnungen 52 sowie durch die vielfache scharfe Umkehr beim Bin- und Austritt im Bereich der Querrohre 32, 34 wird der Dampfdruck so stark vermindert, daß der Dampf ohne wesentlichen Überdruck und ohne Geräusch ins Waschwasser eintritt, wo-er unter Wärmeabgabe vollends kondensiert.Due to the multiple throttling of the flowing steam by the screws 38, also at the bottom of the cap 42 the slots 46, the bore 48 and the outlet openings 52 as well as by the multiple sharp reversals at Bin and exit in the area of the cross tubes 32, 34 is the steam pressure is reduced so much that the steam enters the wash water without significant excess pressure and without making any noise occurs, where it condenses completely, giving off heat.
