Door locking device for household appliances and the appliance

Abstract

This document describes a door locking device (1) for a household appliance having a stationary structure (100) associated with a door (101) and the appliance. The device (1) comprises: a support body (2) designed to be fastened to one of said stationary structure (100) and said door (101) according to a respective resting plane (P); a locking member ( 3), mounted on the support body (2) via corresponding restraint means (4) defining a first axis of rotation, the locking member (3) being designed to cooperate with said stationary structure (100) and said door (101) At least one retaining element (7) of the other cooperates; - an actuation system comprising an electric actuator (5) and a transmission arrangement on the support body (2) for transferring the actuation produced by the electric actuator (5) motion is transmitted to the locking member (3), the actuation system is controllable for causing the locking member (3) about the aforementioned first axis angular movement between the following states: a first non-operating state, wherein the locking member ( 3) Not engaged with the retaining element (7) for being able to manually apply a first opening force (F) to the door (101) 1 ) to open the door (101); and an operating state in which the locking member (3) is engaged with the retaining element (7) for also resisting said first opening force (F 1 ) to keep the door (101) in the closed position. The door locking device (1) further comprises a hinge arrangement (20) pre-arranged for the first body part of the supporting body (2) or 25 thereof associated with the restraining means (4) of the locking member (3) Capable of angular displacement relative to the stationary structure (100), correspondingly relative to the door (101), about a second axis of rotation substantially parallel to said rest plane (P), thereby altering the first axis (X 1 ) and the distance between the resting plane (P).

Description

technical field [0001] The invention relates to a door locking device for a domestic appliance, in particular an oven, having the features stated in the preamble of claim 1 . Devices of this type are known, for example, from patent EP 1640493 A2 and patent EP 1703212 A2 filed in the applicant's name. Background technique [0002] As explained in the introductory part of the aforementioned prior document, devices of the type referred to generally comprise a body, associated with which is a movable locking member and a corresponding actuation system which can be electrically controlled relative to the A suitable retaining element displaces the locking member between an operative or engaged condition and an inoperative or released condition. The body of the door locking device is usually fixed to the stationary structure of the appliance, the locking member of which is able to cooperate with a retaining element defined or mounted on the appliance door. In some cases, instead,...
