Description
Claims (8)
- Gas-Warmwasserbereiter, insbesondere Gasdurchlauferhitzer, mit einem Gasbrenner (5,6) und einer elektrischen Speiseeinrichtung, die die zum Betrieb der elektrischen Aggregate des Warmwasserbereiters benötigte elektrische Energie erzeugt,
dadurch gekennzeichnet, daß die Speiseeinrichtung eine im fetten Abgasstrom des Gasbrenners (5,6) liegende Lambdasonde (7) aufweist. - Gas-Warmwasserbereiter nach Anspruch 1, dadurch gekennzeichnet, daß die Lambdasonde (7) so eingerichtet ist, daß sie bei einem Leistungsbedarf der elektrischen Aggregate von etwa 100 mW einen Strom von wenigstens 300 mA liefern kann.
- Gas-Warmwasserbereiter nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Lambdasonde (7) ein Zirkondioxidplättchen aufweist.
- Gas-Warmwasserbereiter nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, daß die Lambdasonde (7), auf der einen Seite mit dem fetten Abgasstrom vom Gasbrenner und auf der anderen Seite mit Sauerstoff aus der Umgebungsluft versorgt wird.
- Gas-Warmwasserbereiter nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Speiseeinrichtung außerdem einen elektrischen Energiespeicher aufweist, der Überschußenergie der Lambdasonde (7) speichern und die zur Zündung des Gases und zur Öffnung der Gasventile benötigte Anfangsenergie zur Verfügung stellen kann.
- Gas-Warmwasserbereiter nach Anspruch 5, dadurch gekennzeichnet, daß der elektrische Energiespeicher ein Kondensator ist.
- Gas-Warmwasserbereiter nach einem der Ansprüche 5 oder 6, dadurch gekennzeichnet, daß die Speiseeinrichtung außerdem einen Gleichspannungs/Gleichspannungswandler aufweist, der die von der Lambdasonde (7) und dem elektrischen Energiespeicher gelieferte Spannung auf ein von einer im Gas-Warmwasserbereiter vorgesehenen Regelelektronik benötigtes Spannungsniveau umsetzt.
- Gas-Warmwasserbereiter nach Anspruch 1, dadurch gekennzeichnet, daß er ein Gasdurchlauferhitzer mit einer durch die Öffnung des Warmwasserhahns aktivierten Zündautomatik ist.
