摘要:
A control device for gas appliances comprises at least one control module having a supporting structure that can be associated to a gas tap and defines a housing, contained within which is at least one first part (25) of a circuit arrangement. The control module comprises command means operable by a user for activating at least one timing function and/or a function of ignition of a gas burner. The first part (25) of the circuit arrangement comprises control means (MC), electrical-interconnection means (25d, 47), and detection means (45) configured for detecting actuation of the command means and supplying corresponding signals to the control means. The electrical-interconnection means comprise first connector means (47), configured for connection to an electromagnet of a safety valve of the gas tap, and second connectors means (25d), configured for connection to a thermo-electric generator of the gas tap. The device further comprises a flame-detecting circuit (FD) that includes: - means (Q1) for causing brief openings of a circuit between the first connector means (47) and the second connector means (25d); and - means (C5) for detecting possible variations of voltage or overvoltages in said circuit between the first connector means (47) and the second connector means (25d) following upon said brief openings.

A control device for gas appliances comprises a circuit arrangement that includes: —a switching circuit, electrically connected between an electromagnet and a thermoelectric generator of a safety valve of a gas tap; —a control circuit (71), designed at least for counting time and configured for controlling the switching circuit; —a command circuit, connected in signal communication with the control circuit (71) at least for the purposes of setting the aforesaid time interval. The circuit arrangement comprises a power-supply module (50), for low-voltage d.c. supply, and the switching circuit belongs to a control module (40) which is designed to be operatively associated to a respective gas tap. The control circuit belongs to a second control module (60) that comprises a wireless-communication circuit, in particular a transceiver circuit, electrically connected to the control circuit (71) and configured for exchange of signals in wireless mode with a remote electronic programming device, which can be used at least for manual setting of the aforesaid time interval.

A washing-agent dispenser (1) for a household washing machine comprises a main casing (2), defining at least a container (3) for a washing agent, and a member (4') for closing said container (3). The closing member (4') comprises a substantially rigid body (4a') made of a first material, associated to which there are sealing means (16'), made at least in part with a second substantially elastic or soft material. Associated to the rigid body (4a') of the closing member (4') there are at least partially elastic or compliant complements (17', 18', 400), which are functionally distinct from the sealing means (16') and are able to undergo deformation in the course of the use of the closing member (4'). The additional complements (17', 18', 400) are made at least in part of an elastic, or soft, or compliant material, in particular of a synthetic type, which can be overmoulded directly on the rigid body (4a') of the closing member (4'). Preferably, a plurality of additional complements (17', 18', 400) is formed in a single component, which can include also said sealing means (16').
摘要:
A door-lock device for an electrical household appliance, in particular an oven, comprises a body (2) to which there is hinged, via a pin (8), a catch (7) that is capable of angular movement, as well as an actuating system (3-5) having actuator means (3) that can be controlled to determine passage of the locking member (7) between a first inoperative condition, in which opening of the door (9) of the household appliance is enabled, and an operative condition, in which opening of the door (9) is prevented. Means (14) are provided for enabling translation of the pin (8), and hence of the catch (7) in order to enable manual release of the device (1) and/or compensation of any possible assembly allowances.
摘要:
A door-lock device for a household appliance comprises a body (2) to which there is hinged, via a pin (8), a catch (7) that is capable of angular movement, as well as an actuating system (3-5) having actuator means (3) that can be controlled to determine passage of the locking member (7) between a first inoperative condition, in which opening of the door (9) of the household appliance is enabled, and an operative condition, in which opening of the door (9) is prevented. Switching means (14) are provided for enabling translation of the pin (8), and hence of the catch (7), between a position of normal operation and a position of special operation, both of which stable. In the position of normal operation, the movement of the catch (7) is obtained via the actuating system (3-5), whilst in the position of special operation the catch (7) can assume a second inoperative condition. The switching means (14) can be actuated by applying on the door (9) a force that is considerably greater than the minimum force necessary for opening the door itself when the catch (7) is located in its first inoperative condition.
