Definitions
- the present invention relates to a device for indicating residual heat in the area of optionally energized heating devices, e.g. of hobs in the household, whereby a relevant representative state occurring during and / or after the energy application of this heating device is evaluated to control a post-heat display which extends beyond the energy application and the states set by adjusting elements for the energy supply to the heating device are represented by displays will.
- optionally energized heating devices e.g. of hobs in the household
- This residual heat also called residual heat, is particularly often used in glass ceramic cooktops with integrated radiation hobs. After at least one of these radiation hobs has been supplied with electrical energy and a relevant minimum temperature has thus been reached, a signal lamp for each heated hotplate or for all hotplates is brought together to light up in such cooktops, specifically to one Duration that is controlled either by a timer or in particular by a temperature sensor.
- the object of the present invention is to develop and implement a user-friendly after-heat indicator.
- a device for displaying residual heat that meets these requirements is characterized according to the invention in that the residual heat display is integrated in the setting display for the energy supply. This can be implemented in such a way that the setting display for the energy supply assumes a state indicating the presence of residual heat at least after the setting phase has ended.
- Further display options for the residual heat in the setting display for the energy supply can be realized in that the decimal point that is usually present and frequently not used, for example, in segment segment displays is used or that a setting display that can be acted upon with luminaire energy is driven with reduced power compared to normal exposure.
- the device according to the invention is characterized in that, in the case of an electronically controlled application of energy to the heating device and setting display, the duration of the residual heat to be displayed is derived from the electronic control unit.
- the effort required to display the residual heat is thus reduced to a minimum, since the display elements of the energy supply are used for the display itself and the existing control electronics can also be used for the control, which are only upgraded in software for the after-heat display got to.
- Both the energy supply values and the residual heat can be displayed particularly cheaply and in a user-friendly manner by the fact that the setting displays indicating the residual heat in addition to the energy supply are arranged in the area of the heating devices.
- the setting displays indicating the residual heat in addition to the energy supply are arranged in the area of the heating devices.
- a correspondingly designed small field can be present for display with the aid of a seven-segment display.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Anzeige von Nachwärme im Bereich von wahlweise energiebeaufschlagten Heizeinrichtungen, z.B. von Kochfeldern im Haushalt, wobei ein während und/oder nach der Energiebeaufschlagung dieser Heizeinrichtung auftretender relevant repräsentativer Zustand zur Ansteuerung einer sich über die Energiebeaufschlagun hinaus erstreckenden Nachwärme-Anzeige ausgewertet wird und wobei die von Einstellorganen für die Energiezufuhr an die Heizeinrichtung eingestellten Zustände durch Anzeigen dargestellt werden.The present invention relates to a device for indicating residual heat in the area of optionally energized heating devices, e.g. of hobs in the household, whereby a relevant representative state occurring during and / or after the energy application of this heating device is evaluated to control a post-heat display which extends beyond the energy application and the states set by adjusting elements for the energy supply to the heating device are represented by displays will.
Diese Nachwärme, auch Restwärme genannt, wird insbesondere häufig zum Einsatz gebracht in Glaskeramik-Kochmulden mit darin integrierten Strahlungskochfeldern. Nachdem zumindet eine dieser Strahlungskochfelder mit elektroenergie beaufschlagt war und damit eine relevante Mindesttemperatur erreicht wurde, wird bei derartigen Kochfeldern eine Signalllampe je aufgeheizte Kochstelle oder für sämtliche Kochstellen gemeinsam zum Aufleuchten gebracht, und zwar auf eine Dauer, die entweder durch ein Zeitglied oder insbesondere durch einen Temperatursensor gesteuert wird.This residual heat, also called residual heat, is particularly often used in glass ceramic cooktops with integrated radiation hobs. After at least one of these radiation hobs has been supplied with electrical energy and a relevant minimum temperature has thus been reached, a signal lamp for each heated hotplate or for all hotplates is brought together to light up in such cooktops, specifically to one Duration that is controlled either by a timer or in particular by a temperature sensor.
Aufgabe der vorliegenden Erfindung ist es, eine bedienerfreundliche Nachwärmeanzeige zu entwickeln und zu realisieren.The object of the present invention is to develop and implement a user-friendly after-heat indicator.
Eine Vorrichtung zur Anzeige von Nachwärme, die diesen Anforderungen entspricht, ist erfindungsgemäß dadurch gekennzeichnet, daß die Nachwärme-Anzeige in die Einstell-Anzeige für die Energiezufuhr integriert ist. Dies ist dahingehend realisierbar, daß die Einstell-Anzeige für die Energiezufuhr zumindest nach Beendigung der Einstellphase eines das Vorhandensein von Nachwärme anzeigenden Zustandes einnimmt.A device for displaying residual heat that meets these requirements is characterized according to the invention in that the residual heat display is integrated in the setting display for the energy supply. This can be implemented in such a way that the setting display for the energy supply assumes a state indicating the presence of residual heat at least after the setting phase has ended.
So ist es nach einer zweckmäßigen Ausgestaltung der erfindungsgemäßen Vorrichtung bei Verwendung einer elektronischen Einstell-Anzeige mit alphanumerischer Zeichendarstellung möglich, die Ansteuerung für die Einstell-Anzeige dahingehend zu ertüchtigen, daß nach Zurückstellung der Einstellorgane in die Null-Stellung die Einstell-Anzeige auf ein Nachwärme anzeigendes Zeichen oder Symbol eingestellt wird.Thus, according to an expedient embodiment of the device according to the invention, when using an electronic setting display with alphanumeric character display, it is possible to upgrade the control for the setting display in such a way that, after the setting members have been reset to the zero position, the setting display for reheating indicating character or symbol is set.
Andererseits oder auch kombiniert damit ist es bei einer elektronisch angesteuerten Einstellanzeige realisierbar, daß diese bei anzuzeigender Nachwärme einer intermittierenden Ansteuerung unterworfen ist.On the other hand, or in combination with it, it can be realized in the case of an electronically controlled setting display that it is subjected to intermittent control when the after-heat is to be displayed.
Weitere Darstellungsmöglichkeiten der Restwärme in der Einstell-Anzeige für die Energiezufuhr lassen sich dadurch realisieren, daß der beispielsweise bei Seiben-Segmentanzeigen üblicherweise vorhandene und häufig nicht benutzte Dezimalpunkt herangezogen wird oder daß eine mit Leuchtenergie beaufschlagbare Einstell-Anzeige gegenüber der Normalbeaufschlagung mit verminderter Leistung angesteuert wird.Further display options for the residual heat in the setting display for the energy supply can be realized in that the decimal point that is usually present and frequently not used, for example, in segment segment displays is used or that a setting display that can be acted upon with luminaire energy is driven with reduced power compared to normal exposure.
Nach einer bevorzugten Ausgestaltung ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß bei einer elektronisch angesteuerten Energiebeaufschlagung der Heizeinrichtung und Einstellanzeige die Dauer der anzuzeigenden Nachwärme aus der elektronischen Ansteuereinheit abgeleitet wird. Der Aufwand, der für die Anzeige der Restwärme betrieben werden muß, ist damit auf ein Mindestmaß reduziert, da für die Anzeige selbst die Anzeigeelemente der Energiezufuhr herangezogen werden und für die Ansteuerung ebenfalls die vorhandene Ansteuerelektronik dienen kann, welche lediglich softwaremäßig für die Nachwärmeanzeige ertüchtigt werden muß.According to a preferred embodiment, the device according to the invention is characterized in that, in the case of an electronically controlled application of energy to the heating device and setting display, the duration of the residual heat to be displayed is derived from the electronic control unit. The effort required to display the residual heat is thus reduced to a minimum, since the display elements of the energy supply are used for the display itself and the existing control electronics can also be used for the control, which are only upgraded in software for the after-heat display got to.
Besonders günstig und benutzerfreundlich sind sowohl die Energiezufuhrwerte wie auch die Nachwärme dadurch anzuzeigen, daß die neben der Energiezufuhr die Nachwärme anzeigenden Einstell-Anzeigen im Bereich der Heizeinrichtungen angeordnet sind. So kann beispielsweise in einer Glaskeramik-Platte mit einer Mehrzahl von gekennzeichneten Heizfeldern ein entsprechend gestaltetes Kleinfeld zur Anzeige mit Hilfe von Sieben-Segment-Darstellung vorhanden sein.Both the energy supply values and the residual heat can be displayed particularly cheaply and in a user-friendly manner by the fact that the setting displays indicating the residual heat in addition to the energy supply are arranged in the area of the heating devices. For example, in a glass ceramic plate with a plurality of marked heating fields, a correspondingly designed small field can be present for display with the aid of a seven-segment display.
Im Rahmen der Erfindung ist es auch möglich, den die Nachwärme anzeigenden Zustand der Einstell-Anzeige durch deren Farbwechsel zu realisieren.Within the scope of the invention it is also possible to realize the state of the setting display indicating the residual heat by changing its color.
