Abstract

The system to evaporate water by electrical heating, e.g. in domestic appliances and electric tools, has a water pump (3) in parallel with a control contact (1), which switches the power supply (12) to the heating element (4) of the evaporator (2) on and off according to temperature. The opening of the control contact maintains the power supply and water is drawn through a suction tube (5) and a connecting tube (6) into an inflow (7), where water is sprayed on to the hot heating surface of the evaporator. Steam, free of droplets, is available at a high pressure at the steam outflow connection (8).

Description

Die Erfindung betrifft eine Einrichtung zum Verdampfen von Wasser mittels elektrischer Beheizung, zur Anwendung in elektrischen Hausgeräten und Elektrowerkzeugen, mit der auf einfachste Weise tropfenfreier Dampf erzeugt wird.The invention relates to a device for evaporating water by means of electrical Heating, for use in household electrical appliances and power tools, with the The simplest way to produce drip-free steam.

Aus DE 4309240 ist bekannt, in einer beheizten flachen Dose mittels einer Pumpe Wasser zur Dampferzeugung zu dosieren, wobei die Pumpe die zu verdampfende Flüssigkeit in einstellbarer Menge dem temperaturgeregelten Verdampfer zuführt. Nachteilig an dieser Schaltung ist, dass die Pumpenleistung durch einen Vorwiderstand verändert wird und die Inbetriebnahme der Pumpe durch einen zusätzlichen Schalter manuell oder mit nicht näher beschriebenen externen Schaltkomponenten erfolgt.From DE 4309240 is known in a heated flat box by means of a pump water for To dose steam generation, the pump to be evaporated liquid in adjustable Supply quantity to the temperature-controlled evaporator. The disadvantage of this circuit is that the pump power is changed by a series resistor and commissioning the Pump by an additional switch manually or with unspecified external Switching components takes place.

In EP 1 026 306 wird ein Dampfgenerator mit Pumpe für ein Bügeleisen beschrieben. Darin ist der große konstruktive Aufwand dargestellt, ohne auf eine elektrische Zusammenschaltung von Pumpe und Heizung einzugehen.EP 1 026 306 describes a steam generator with a pump for an iron. That's it the great design effort shown, without relying on an electrical interconnection of To enter pump and heating.

Es ist auch aus EP 1 151 705 bekannt, die Temperatur eines Dampfbackraumes durch Zuführung von Wasser auf einen im Backraum angeordneten Dampfgenerator zu regeln. Darin wird der Prozess der Dampferzeugung durch ein aufwendiges Mess- und Auswertesystem geregelt. Diese aufwendige und auf den speziellen Anwendungsfall beschränkte Anordnung ist für einfachste Lösungen nicht sinnvoll zu gebrauchen,It is also known from EP 1 151 705, the temperature of a steam oven by feeding to regulate water on a arranged in the oven steam generator. This is where the Process of steam generation regulated by a complex measuring and evaluation system. These complex and limited to the specific application arrangement is for the simplest Not to use solutions meaningfully,

In Espressomaschinen wird kontinuierlich Wasser in einem Verdampfer aus Aluminiumguß zum Kochen und Verdampfen gebracht. Nachteilig an diesem Verfahren ist, dass die Autheizzeit lang ist, der Wasserdampf nicht tropfenfrei zur Verfügung steht, denn für Espressomaschinen gibt es diese Forderung nicht, und Verdampfer aus Aluminium sehr stark zur Bildung von Rückständen neigen.In espresso machines is continuously water in an evaporator made of cast aluminum for Brought cooking and evaporation. A disadvantage of this method is that the car heating time long is that water vapor is not available drip-free, because there are espresso machines this requirement is not, and aluminum evaporators very strong to the formation of residues tend.

Aufgabe der Erfindung ist eine Einrichtung zum Verdampfen von Wasser mittels elektrischer Beheizung, mit der auf einfachste Weise und mit einem Minimum an kostengünstigen Komponenten tropfenfreier Wasserdampf zur Anwendung in elektrischen Hausgeräten und Elektrowerkzeugen erzeugt wird.The object of the invention is a device for evaporating water by means of electrical Heating, in the simplest way and with a minimum of cost Components drip-free water vapor for use in household electrical appliances and Power tools is generated.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Hauptanspruchs gelöst. Ausgestaltungen der Erfindung sind in den Unteransprüchen dargestellt.According to the invention the object is achieved by the features of the main claim. Embodiments of the invention are shown in the subclaims.

Der Vorteil der Erfindung besteht darin, dass auf einfachste Weise mit einem Minimum an Komponenten troplenfreier Wasserdampf erzeugt wird und die erfindungsgemäße Einrichtung als selbständig arbeitende Komponente Verwendung findet. Ein weiterer Vorteil ist, dass durch den massearmen Aufbau des Verdampfers die Arbeitstemperatur schnell erreicht ist und durch kleine Totzeiten bei Änderung der Versorgungsspannung auch eine sofortige Änderung der Dampfleistung erfolgt. The advantage of the invention is that in the simplest way with a minimum Components troplenfreier water vapor is generated and the inventive device is used as a self-contained component. Another advantage is that through the low-mass construction of the evaporator the working temperature is reached quickly and through small dead times with change of the supply voltage also an immediate change of the Steam power occurs.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert.The invention will be explained in more detail with reference to an embodiment.

Die Einrichtung wird durch Anlegen der Versorgungsspannung 12 mit dem Heizelement 4 am Boden des Verdampfers 2 aufgeheizt.The device is by applying the supply voltage 12 to the heating element 4 am Bottom of the evaporator 2 heated.

Beim Erreichen einer durch den Reglerkontakt 1 bestimmten Temperatur, zum Beispiel 160° C, öffnet der Reglerkontakt 1 und schaltet das Heizelement 4 von der Versorgungsspannung 12 ab. In Folge liegt ein großer Teil der Versorgungsspannung 12 an dem Reglerkontakt 1 und die Wasserpumpe 3 beginnt über den Ansaugschlauch 5 sowie den Verbindungsschlauch 6 Wasser in den Wasserstutzen 7 des Verdampfers 2 zu spritzen. Das Wasser verdampft in dem aufgeheizten Verdampfer 2 sofort und steht am Dampfstutzen 8 tropfenfrei als Dampf mit hohem Druck zur Verfügung. Dabei kühlt der Verdampfer 2 ab und beim Erreichen einer ebenfalls durch den Reglerkontakt 1 bestimmten Temperatur zum Beispiel 120° C, schließt der Reglerkontakt 1 wieder, die Wasserpumpe 3 erhält die Versorgungsspannung 12 nicht mehr und das Heizelement 4 wird erneut beheizt. Dieser Vorgang wiederholt sich laufend.Upon reaching a temperature determined by the regulator contact 1, for example 160 ° C., opens the regulator contact 1 and turns off the heating element 4 from the supply voltage 12. As a result, a large part of the supply voltage 12 at the regulator contact 1 and the Water pump 3 starts via the suction hose 5 and the connecting hose 6 water to squirt into the water nozzle 7 of the evaporator 2. The water evaporates in the heated Evaporator 2 immediately and is at the steam pipe 8 drip-free as steam with high Pressure available. In this case, the evaporator 2 cools down and when reaching a likewise by the regulator contact 1 certain temperature, for example, 120 ° C, closes the Reglerkontakt 1 again, the water pump 3 receives the supply voltage 12 is no longer and the heating element 4 is heated again. This process is repeated continuously.

Die Versorgungsspannung 12 steht beim Heizen am Heizelement 4 ganz zur Verfügung und beim Wasserpumpen an der Wasserpumpe 3 fällt ein kleiner Teil dieser Spannung am Heizelement 4 ab. Da aber der elektrische Pumpenwiderstand sehr viel größer ist (ungefähr einhundert mal) als der elektrische Widerstand des Heizelementes 4, liegt beim Pumpen nach derThe supply voltage 12 is completely available when heating the heating element 4 and When water pumping on the water pump 3, a small part of this voltage falls on Heating element 4 from. But since the electrical pump resistance is much larger (about one hundred times) as the electrical resistance of the heating element 4, is when pumping after the

Spannungsteilerregel trotzdem ein großer Teil der Versorgungsspannung 12 an der Wasserpumpe 3 an.Voltage divider rule anyway, a large part of the supply voltage 12 to the water pump 3 on.

Zur Sicherheit ist der Reglerkontakt 1 mit der Thermosicherung 9 in Reihe geschaltet und beide befinden sich außen an der im Betrieb heißesten Stelle am Boden des Verdampfers 2. Auf diese Stelle wird auch innen im Verdampfer 2 das zu verdampfende Wasser aus dem Wasserstutzen 7 gespritzt.For safety, the regulator contact 1 is connected in series with the thermal fuse 9 and both are located on the outside of the hottest point at the bottom of the evaporator 2. On this Place is also inside the evaporator 2, the water to be evaporated from the water pipe. 7 injected.

Vorteilhafterweise besteht das Gehäuse des Verdampfers 2 aus Edelstahlblech, ist damit massearm und hat sehr kurze Aufheizzeiten. Das Gehäuse hat ein Volumen von ungefähr 100 Milliliter und ist sehr flach ausgebildet. Der Durchmesser der Grundfläche ist ungefähr zehn mal größer als die Höhe. Die Form des Verdampfers 2 muß nicht zylindrisch sein. Das ist zwar technologisch vorteilhaft, es sind aber auch andere Geometrien geeignet. In einer vorteilhaften Ausgestaltung der Erfindung ist der Verdampfer 2 um den Schrägstellungswinkel 10 zur Horizontalen geneigt. Dieser Winkel ist zum Beispiel zwischen 5° und 10° und die Neigung ist immer so, dass das Wasser auf die Seite des Wasserstutzens 7, also auf die im Betrieb heißeste Stelle, fließt.Advantageously, the housing of the evaporator 2 made of stainless steel sheet is so massearm and has very short heating times. The housing has a volume of about 100 Milliliter and is very shallow. The diameter of the base is about ten times greater than the height. The shape of the evaporator 2 need not be cylindrical. That is true technologically advantageous, but other geometries are suitable. In an advantageous embodiment of the invention, the evaporator 2 is at the skew angle 10 inclined to the horizontal. This angle is for example between 5 ° and 10 ° and the Slope is always such that the water on the side of the water nozzle 7, so on the in Operation hottest place, flows.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung befindet sich im Inneren des Verdampfers 2 ein Prallblech 11 vor dem Dampfstutzen 8. Damit wird verhindert, dass sprudelndes Wasser aus dem Dampfstutzen 8 herauskommt.In a further advantageous embodiment of the invention is located inside the Evaporator 2 a baffle 11 in front of the steam pipe 8. This prevents bubbling water comes out of the steam pipe 8.

Es ist auch vorteilhaft, dass die Dampfmenge auf einfachste Weise nur durch Verändern der Versorgungsspannung 12 erfolgt, denn mit der elektrischen Leistung des Heizelementes 4 ändern sich auch die Schaltzeiten des Reglerkontaktes 1 und damit die Intervalle der Dampferzeugung.It is also advantageous that the amount of steam in the simplest way only by changing the Supply voltage 12 takes place, because with the electrical power of the heating element 4 change also the switching times of the regulator contact 1 and thus the intervals of steam generation.
