A door-locking device for a self-cleaning oven includes a support configured to be fixed to a frame of the oven. A main slider is movable relative to the support along a longitudinal rectilinear direction, and is configured to be pushed elastically towards an extracted position and pushed by the door of the oven towards a retracted position. A locking arm is coupled to the support around an articulation axis perpendicular to the longitudinal rectilinear direction and oscillates around the articulation axis between an unlocked position and a locked position. A transmission mechanism connects the locking arm to the main slider and is arranged to swing the locking arm from the unlocked position to the locked position and vice versa via movement of the main slider from the extracted position to the retracted position, and vice versa. An electromagnetic switch includes an electromagnet that drives a movable member associated with a locking pin arranged to lock the main slider in the retracted position.

A switch assembly for controlling the ignition of gas burners of a cooking appliance having one or more gas valves. The switch assembly includes at least one first support member, operably couplable to a first gas valve, a spring biased ignition switch operably mountable to the at least one first support member, and an actuating member, having a longitudinal axis and operably couplable to at least the first gas valve between the at least one first support member and at least a control knob of at least the first gas valve. The actuating member is adapted to move between a first position, actuatingly engaged with the ignition switch, and a second position, actuatingly disengaged from the ignition switch, wherein the actuating member is moved towards the first position by at least the control knob, and back towards the second position by the spring biased ignition switch.

A device is provided for controlling the ignition of gas burners of a domestic cooking appliance. The device includes an electric switch with an insulating casing that carries a pair of fixed electric contacts. A movable body carries a movable electric contact that cooperates with the fixed electric contacts. The movable body is displaceable with respect to the casing between an open position and a closed position. An elastic element elastically pushes movable body toward the open position. A flexible cable has a first end that is anchored to the movable body and a second end that is anchored to a fixed support. A plurality of actuating members is associated with respective gas taps and have movable elements that cooperate with respective sections of the flexible cable. Each actuating member can bend a respective portion of the flexible cable into corrugated shape during the opening of the respective gas tap.

A device, for automatic extraction of a supply drawer from a household appliance, includes a releasable locking device for releasably locking the drawer; an elastic element for pushing the drawer into an extracted position; a braking element for opposing movement of the drawer; a support housing the elastic and the braking elements; and a toothed pinion fitted idly to the support, which is configured to leave at least one given circumferential portion of the teeth of the pinion exposed. The elastic element is to exert a torque in a given direction on the pinion, which is connected angularly integral with the braking element. The exposed circumferential portion of the pinion teeth meshes selectively with a straight or curved rack, formed externally on a wall of the drawer, by simply rotating the support with respect to the drawer, so that the same device can be used for both slide-out and swing-out drawers.

A knob includes a hub to be fixed in a seat open at the front of an electrical household appliance, a grip, which can slide axially, against the action of an elastic element, on a first end of the hub. Between the grip and the hub there is defined a closed chamber having a variable volume that is a function of the axial position of the grip on the hub. A sliding seal is provided for sealing the closed chamber. A calibrated restriction connects the inside of the chamber with the external environment in such a way as to bring about a negative pressure in the chamber as a result of the axial movement of the grip away from the hub.
