Abstract
Description
Die Erfindung betrifft eine Temperaturanzeigeeinrichtung nach dem Oberbegriff des Patentanspruchs 1 bzw. 2.The invention relates to a temperature display device according to the preamble of claim 1 or 2.
Die Temperatur der Tür für einen beheizten Back-, Brat- und Garraum eines Herdes oder dergleichen soll möglichst nied rig gehalten werden, um die Gefahr einer Verbrennung beim Berühren der Tür während des Beheizungsvorganges zu vermei den. Trotz verschiedener Maßnahmen zur Vermeidung von hohen Temperaturen an der Türaußenseite läßt es sich in vielen Fällen aber gar nicht verhindern, daß sich die in der Regel aus Glas bestehende Türaußenseite trotzdem stark aufheizt. Nachdem für den Benutzer eines solchen Herdes nun nicht er kennbar ist, ob die Backraumtür eine erhöhte und damit ge fährliche Temperatur erreicht hat, besteht immer die Ge fahr, daß diese gedankenlos berührt wird. Herde der in Rede stehenden Art haben zwar in der Bedienungsblende eine mit Einschalten der Backraumheizung auf leuchtende Anzeigeein richtung, diese erlischt jedoch, wenn die vorgewählte Back raumtemperatur erreicht worden ist.The temperature of the door for a heated baking, roasting and Cooking space of a stove or the like should be as low as possible rig be held to reduce the risk of burns at the Avoid touching the door during the heating process the. Despite various measures to avoid high There are many temperatures on the outside of the door However, cases do not prevent them from happening as a rule door exterior made of glass still heats up strongly. After for the user of such a stove, now not him it is recognizable whether the baking chamber door is raised and therefore ge has reached dangerous temperature, there is always the Ge drive that this is touched thoughtlessly. Herd of in speech standing type have in the control panel with Switch on the baking space heating on the illuminated display direction, however, this disappears when the selected baking room temperature has been reached.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein be heiztes Haushaltsgerät der in Rede stehenden Art mit einfa chen und nur minimale Kosten erfordernden Maßnahmen so zu verbessern, daß der Benutzer einen deutlichen Hinweis er hält, wenn die Backraumtür einen für diesen gefährlichen Temperaturwert hat.The invention is therefore based on the object heated household appliance of the type in question with sim measures that require minimal costs improve that the user has a clear indication he stops if the oven door is dangerous for him Temperature value.
Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kenn zeichnenden Teil des Patentanspruchs 1 bzw. 2 zu entnehmen. Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.The solution to this problem according to the invention is known drawing part of claim 1 or 2. Advantageous further refinements of the subject of Invention are specified in the subclaims.
Die Erfindung wird nachfolgend anhand mehrerer in der Zeichnung dargestellter Ausführungsbeispiele näher be schrieben.The invention is based on several in the Drawing illustrated embodiments in more detail be wrote.
Die einzelnen Figuren der Zeichnung zeigen als bevorzugte Ausführungsbeispiele Haushaltsgeräte mit einem elektrisch beheizten Ofenraum zum Backen, Braten und Garen von Nah rungsmitteln.The individual figures of the drawing show as preferred Exemplary household appliances with an electrical heated oven space for baking, roasting and cooking from close-up resources.
Das Haushaltsgerät 1 nach der Zeichnung hat einen elek trisch beheizten Ofenraum, dessen Beschickungsöffnung durch eine Tür 2 verschlossen ist. Die Tür 2 besteht aus einer Frontglasscheibe 3, in der durch entsprechende Einfärbungen 4 ein Sichtfenster 5 begrenzt bzw. umrahmt ist.The household appliance 1 according to the drawing has an electrically heated furnace chamber, the loading opening of which is closed by a door 2 . The door 2 consists of a front glass pane 3 , in which a viewing window 5 is delimited or framed by corresponding coloring 4 .
Zwecks Warnung des Benutzers vor einer für eine Berührung der Tür 2 gefährlichen Temperatur ist im Türflächenbereich und zwar unterhalb des Sichtfensters 5 ein temperaturfüh lendes Element 6 mechanischer, chemischer oder elektroni scher Art angebracht, das mit zunehmender bzw. steigender Türtemperatur einer Verfärbung ausgesetzt ist und damit durch eine Farbänderung die erhöhte Türtemperatur zur An zeige bringt. Das temperaturfühlende Element 6 ist beim Ausführungsbeispiel nach Fig. 1 als horizontal und paral lel zum Sichtfenster 5 verlaufende Temperatur-Skalen-Leiste ausgeführt, die sich mit ansteigender Temperatur von links nach rechts entsprechend der angegebenen Temperaturwerte unterschiedlich stark verfärbt und dadurch die jeweils ak tuelle Temperatur der Tür 2 signalisiert.For the purpose of warning the user of a dangerous temperature for touching the door 2, a temperature-sensing element 6 of a mechanical, chemical or electronic type is attached in the door surface area, namely below the viewing window 5 , which is exposed to discoloration with increasing or increasing door temperature and thus displays the increased door temperature by changing the color. The temperature-sensing element 6 is designed in the embodiment of FIG. 1 as a horizontal and parallel to the viewing window 5 running temperature scale bar, which changes color with increasing temperature from left to right according to the specified temperature values and thereby the respective current temperature the door 2 signals.
Nach Fig. 2 verläuft das leistenartige temperaturfühlende Element 6' vertikal und parallel zum Sichtfenster 5. Dieses Element weist bei kalter Tür 2 eine unscheinbare und mit zunehmender Türtemperatur eine intensive bzw. eine ins Auge fallende Färbung auf, z. B. eine von, blau nach rot überge hende Verfärbung. Mit Sichtbarwerden eines am Ende des lei stenförmigen temperaturfühlenden Elementes 6' angeordneten Symbol 7 wird angezeigt, daß die Tür 2 sich in einem ge fährlichen Temperaturbereich befindet.According to FIG. 2, the strip-like temperature-sensitive element 6 'extends vertically and parallel to the viewing window 5. With cold door 2, this element has an inconspicuous and with increasing door temperature an intense or eye-catching coloration, e.g. B. from blue to red passing discoloration. With a visible at the end of the lei-shaped temperature-sensing element 6 'arranged symbol 7 it is shown that the door 2 is in a dangerous temperature range.
Im Ausführungsbeispiel nach Fig. 3 besteht das temperatur fühlende Element lediglich aus einem neben dem Sichtfenster 4 angeordneten Symbol 8, das nach Erreichen einer sichtba ren Färbung den kritischen Temperaturpunkt der Tür 2 signa lisiert. In the exemplary embodiment according to FIG. 3, the temperature-sensing element consists only of a symbol 8 arranged next to the viewing window 4 , which signals the critical temperature point of the door 2 after reaching a visible color.
Das temperaturfühlende Element 6, 7, 8 ist zweckmäßig an der Innenseite der Garraumtür angebracht und kann aus einer leicht anzubringenden leistenartigen Folie oder dergleichen bestehen, die mit den genannten Zweck erfüllenden chemi schen Substanzen, die sich bei Temperaturänderung sichtbar verfärben, ausgerüstet ist.The temperature-sensing element 6 , 7 , 8 is expediently attached to the inside of the cooking space door and can consist of an easy-to-install strip-like film or the like, which is equipped with the stated chemical chemicals that visibly change color when the temperature changes.
