Abstract
A safety interlock device for an electrically driven household mixing apparatus includes a safety switch operatively connected with electric circuit of a drive motor of the apparatus and of an arrangement for heating a container of the apparatus, a switching rod longitudinally movable between switch-on and switch-off positions causing the switch to move respectively to its on and off positions, a holding lever pivotally mounted on the switching rod for turning between closed and open positions in which its end respectively abuts against a cover of the container and is withdrawn from the same, an arm provided with a temperature sensing element and movable between a proximal and distal positions in which the temperature sensing element respectively contacts a wall of the container and is withdrawn from the same, an actuating lever pivotally movable between a first position in which it keeps the holding lever in the closed position and through the intermediary of the holding lever keeps the switching rod in the switch-on position and a second position in which the actuating lever does not keep these parts in such positions, and a transmission element mounted on the actuating lever and operative when the latter is moved to its first position for moving the arm with the temperature sensing element to its proximal position.
