发明名称 Domestic appliance having automatic switch-off
摘要 A method and apparatus for autonomously switching off a domestic appliance after completion of a previously selected program is disclosed. The domestic appliance has a control device that executes programs controlling the domestic appliance and an operating unit. The domestic appliance is connected to electrical energy from a power source through circuit arrangement comprising a terminal connection and first and second switches. The first electrical switch is separate from the second switch and can be switched from an open state to a closed state in which the switch is electrically conductive to connect the control device to the electrical energy. The control device is designed to switch the second switch from an open state to a closed state in which the control device is connected to electrical energy through the second switch as soon as the first switch is switched to the closed switching state.

主权项 1. A circuit arrangement for operating a domestic appliance, comprising: a control device for executing programs of the domestic appliance; a terminal connection, through which the domestic appliance can be supplied with electrical energy from a supply network; a first electrical switch, said control device being adapted to be coupled to the terminal connection through said first electrical switch; an operating unit connected to the terminal connection, said operating unit selecting programs for said control device, said operating unit having a fixed contact element and a mobile contact element, said mobile contact element being adapted to move relative to the fixed contact element when the operating unit is actuated by an operator, said mobile contact element being electrically coupled to the fixed contact element when the operating unit is not in a starting position, said first electrical switch being switched from an open state to a closed state in which the first switch is electrically conductive in response to an actuation of the operating unit; and a second electrical switch, said first and second electrical switches being separate from each other, said control device being adapted to be coupled to the terminal connection through said second switch, said second switch being switched from an open state to a closed state in which the control device is coupled to the terminal connection through the second switch as soon as the first switch is switched to the closed state.
