Abstract

L'invenzione riguarda uno scaldacqua funzionante elettricamente, specialmente uno scaldacqua istantaneo a passaggio, con un dispositivo di sicurezza (50, 54, 58) intervenente automaticamente, il quale interrompe il raccordo della rete dell'apparecchio, quando la pressione rispettivamente la temperatura dell'acqua riscaldata nell'apparecchio raggiunge un valore limite preassegnabile, e inoltre con un dispositivo, da comandare dall'utente, per impostare gradualmente la potenza di riscaldamento (18, 10) dell'apparecchio. Viene proposto che al dispositivo per impostare la potenza di riscaldamento (18, 20) e al dispositivo di sicurezza (50, 54, 58) intervenente automaticamente è associata in comune una unica combinazione di interruttori (12, 14, 16), ed entrambi i dispositivi, agendo indipendentemente l'uno dall'altro, sono accoppiati con la combinazione di interruttori (12, 14 e 16).La disposizione secondo l'invenzione presenta il vantaggio consistente nel fatto che per il dispositivo di sicurezza e per il dispositivo per impostare la potenza di riscaldamento è necessaria una unica combinazione di interruttori, ed il meccanismo interruttore può essere eseguito in modo semplice e di sicuro funzionamento (figura 3).The invention relates to an electrically operated water heater, especially an instant passage water heater, with a safety device (50, 54, 58) intervening automatically, which interrupts the connection of the appliance network, when the pressure respectively the temperature of the heated water in the appliance reaches a pre-assignable limit value, and also with a device, to be controlled by the user, to gradually set the heating power (18, 10) of the appliance. It is proposed that the device for setting the heating power (18, 20) and the safety device (50, 54, 58) automatically intervening is associated in common with a single combination of switches (12, 14, 16), and both devices, acting independently of each other, are coupled with the combination of switches (12, 14 and 16). The arrangement according to the invention has the advantage consisting in that for the safety device and for the device for setting the heating power requires a single combination of switches, and the switch mechanism can be performed easily and safely (figure 3).
