Description
Gegenstand den Erfindung ist ein Warmhalter von Flüssigkeiten in Röhren, Schläuchen u. dgl. nach dem Abstellen: des Warmwasserdurchflusses, damit bei neuem Fluß nicht erst das im Schlauch erkaltete Wasser abfließen muß, scndern gleich warmes Wasser fließt.The subject of the invention is a heat holder for liquids in tubes, Hoses and the like after switching off: the hot water flow, so when the new one The water that has cooled down in the hose does not have to flow off first, and the warm water is changed straight away Water flows.
Diese Forderung stellen u. a. Ärzte, Zahnärzte und Friseure. Weil der kalte Wasserstrahl aus dem Schlauch bei dem -Behandelten einen Schock auslöst, wird das kalte Wasser erst abgelassen. Dadurch treten immer wiederkehrende Verluste an Zeit, «'assen und Verzögerungen in der Behandlung auf. Das sind Mängel, die durch den Gegenstand der Eifindung beseitigt werden.This requirement is made inter alia. Doctors, dentists and hairdressers. because the cold water jet from the hose triggers a shock when the person is being treated, the cold water is first drained off. This leads to recurring losses in terms of time, consumption and delays in treatment. These are shortcomings caused by the object of the invention will be eliminated.
Die Zeichnung zeigt ein Beispiel. In Fig. 1 ist 4 eine Fontäne zur Mundspülung. Im Gehäuse 1 be#-findet sich der Warmwasserbereiter. Bei 5 fließt das kalte Wasser zu, bei 2 fließt das warme Wasser durch den Regler zum Schlauch 7, mit Auslauf bei 4, sobald die Gabe13 entlastet wird.The drawing shows an example. In Fig. 1, 4 is a fountain for Mouthwash. The water heater is located in housing 1. At 5 it flows cold water, at 2 the warm water flows through the regulator to hose 7, ending at 4 as soon as the Gabe13 is relieved.
Es vergehen etwa 45 Sekunden, ehe das warme Wasser bei .4 austritt, weil das kalte Wasser im Schlauch erst abfließen muß.It takes about 45 seconds before the warm water comes out at .4, because the cold water in the hose has to drain off first.
Nach der Erfindung wird um den Schlauch 7 (Fig. 1) der Draht 8 gewickelt, einlagig, bifilar, bei 6 beginnend. Die zwei Drahtenden werden durch den Ring mit Rohransatz 9 (s. a. F,ig. 4) in das Innere des Gehäuses 1 zum Transformator T geführt und dort an die Sekundärwicklung (12 Volt) angeschlossen. 1o und 11 (Fig. 1) bezeichnen zwei benachbarte Windungen der Heizwicklung 8, die jeweils von diern Strom in entgegengesetzter Richtung durchflossen werden, wie durch Pfeile angedeutet. Der Heizdraht 8 wird so bemessen, daß das in dem Schlauch befindliche Wasser nicht unter 40° C abkühlen kann. Die genannten Mängel sind also beseitigt, eine Gefahr für den Patienten durch elektrischen Strom ist ausgeschlossen, und die Aufrechterhaltung einer Temperatur von 40° C schadet auch dem Schlauchmaterial nicht.According to the invention, the wire 8 is wound around the hose 7 (Fig. 1), single-ply, bifilar, starting at 6. The two wire ends are through the ring with Pipe socket 9 (see also F, fig. 4) led into the interior of the housing 1 to the transformer T. and connected there to the secondary winding (12 volts). 1o and 11 (Fig. 1) two adjacent turns of the heating coil 8, each of which is in opposite direction from the diern Direction are flowed through, as indicated by arrows. The heating wire 8 is dimensioned so that the water in the hose does not cool below 40 ° C can. The above-mentioned deficiencies have thus been eliminated, putting the patient at risk electric current is excluded and the maintenance of a temperature of 40 ° C does not damage the hose material either.
In Fig. 2 ist der Schlauch 12, wie die Pfeile 13 und 14 zeigen, nicht bifilar gewickelt, es entsteht also ein Magnetfeld im Schlauch. Dieses Magnetfeld kann bei Wechselstrom induktiv Wärme erzeugen, wie in Fig. 3 gezeigt wird. In dem Schlauch 15 ist innen das Eisendrahtgeflecht 16, darüber das Kupferdrahtgeflecht 19 eingearbeitet. Das Magnetfeld aus der Spule 18 schließt sich kräftig im Eisen 16, schneidet dabei die Kurzschlußkupferwicklung 19. Es entstehen starke Ströme in 19, gerichtet um den Schlauch 15, die ganz in Wärme umgesetzt werden und das Wasser im Schlauch 15 erwärmen, wie beabsichtigt. Die äußere Stoffuinflechtung 17 verdeckt die @'ficklung 18. Es kann aber auch die Wicklung 18 wie die Geflechte 16 und 19 im Schlauch verarbeitet liegen. Eisengeflecht 16 und Kupferwicklung 19 (Fig. 3) dürfen sich direkt berühren, also metallisch aneinanderliegen. 16(Fig.3) braucht kein Eisengeflecht zu sein, es genügt auch eine Eisendrahtspirale, 19 muß im Umfang metallisch geschlossen sein, etwa nebeneinanderliegende Kupferringe, die als sekundäre Kurzschlußwicklungen wirken. Falls statt eines Schlauches ein Rohr erwärmt werden soll, muß dieses ein Eisenrohr mit Messing- oder Kupferüberzug sein.In Fig. 2, as the arrows 13 and 14 show, the hose 12 is not bifilar wound, so a magnetic field is created in the tube. This magnetic field can generate heat inductively with alternating current, as shown in FIG. 3. By doing Hose 15 is inside the iron wire mesh 16, above the copper wire mesh 19 incorporated. The magnetic field from the coil 18 closes strongly in the iron 16, cuts the short-circuit copper winding 19. Strong currents arise in 19, directed around the hose 15, which are completely converted into heat and that Heat the water in the hose 15 as intended. The outer fabric weave 17 covers the @ 'ficklung 18. It can also be the winding 18 like the braids 16 and 19 are processed in the tube. Iron mesh 16 and copper winding 19 (Fig. 3) may touch each other directly, i.e. lie against each other in a metallic manner. 16 (Fig. 3) does not need to be an iron mesh, an iron wire spiral is also sufficient, 19 must be metallic in the scope, such as adjacent copper rings that act as secondary short-circuit windings. If a pipe is used instead of a hose is to be heated, this must be an iron pipe with a brass or copper coating.
Das erste Anheizen des Warmwasserbereiters dauert etwa 40 Minuten, es steht also für die ersten Patienten noch kein warmes Wasser zur \'erfügung. Hier ist auch der geheizte Schlauch ein Fortschritt, denn er hält nicht nur das Wasser warm, sondern erwärmt auch das kalbe Wasser im Schlauch, so daß kleine Mengen Wasser gleich bereit sind. Die Stromzuführung zum Schlauch wird völlig verdeckt und eingeschlossen durchgeführt. Fig.4 zeigt bei 2o den Ring mit Rohransatz und 21 das Rohr.It takes about 40 minutes to heat up the water heater for the first time. So there is still no warm water available for the first patients. here the heated hose is also a step forward, because it not only holds the water warm, but also warms the calf water in the hose, leaving small amounts of water are ready soon. The power supply to the hose is completely covered and enclosed carried out. Fig. 4 shows at 2o the ring with tube attachment and 21 the tube.
