Patent number: 11788340Abstract: A domestic electrical appliance includes an appliance main body having an access opening to a usable chamber formed inside the appliance main body, and a door which is movably mounted on the appliance main body and which in an open position frees the access opening and in a closed position closes the access opening, a door latch for holding the door closed in the closed position, and a door opener, structurally separate from the door latch, for opening the closed door. The door opener includes a first coupling structure displaceably arranged on one of the appliance main body and the door, an electrically controllable drive unit for driving the first coupling structure, and a second coupling structure arranged on the other of the appliance main body and the door. The first and second coupling structure are configured for push- and pull-transmitting but releasable coupling engagement with one another.Type: GrantFiled: May 3, 2021Date of Patent: October 17, 2023Assignee: EMZ-HANAUER GMBH & CO.

Patent number: 11174581Abstract: A door latch for an electrical domestic appliance includes a rotary member rotationally movable in a rotation plane between a closing rotational position and a release rotational position, a movably arranged catch for arresting engagement by an overlifting rotational movement of the rotary member with the rotary member in its closing rotational position, and a locking assembly having a locking member movable between an unlocking position and a locking position. The rotary member is spring-biased towards the release rotational position and which, in the closing rotational position, holds a closure member to keep a door closed and, in the release rotational position, releases the closure member in order for the door to open. The locking member forms a first blocking arrangement by means of which the locking member in its locking position blocks the rotary member against rotation out of the closing rotational position into the release rotational position.Type: GrantFiled: July 12, 2018Date of Patent: November 16, 2021Assignee: EMZ-HANAUER GMBH & CO.

Patent number: 10806322Abstract: A door latch for a domestic electrical appliance includes a latch assembly that includes a locking element arranged to be displaceable between an unlocking position and a locking position, and an arresting element which moves from its release position into the arresting position as the door is closed. The arresting element in the arresting position can be locked by means of the locking element against movement into the release position and in the locked state prevents the closed door from opening. The latch assembly further includes an electric switch which, when the door is closed, responds to a movement of the locking element from the unlocking position into the locking position, and a switch auxiliary control member which, as the door is closed, is urged by the closing body from an active position against a restoring spring force into an inactive position.Type: GrantFiled: July 6, 2017Date of Patent: October 20, 2020Inventors: Albert Dirnberger, Dominik Walz, Markus Lang

Patent number: 10240372Abstract: A door latch for an electrical household appliance includes a latch housing in which a gripping unit is received. The door latch further includes a first arresting element which is received in the latch housing such that it is movable between a release position and an arresting position. In the arresting position, the first arresting element blocks the gripping unit to prevent rotation into the open rotational position and, in the release position, permits a rotation of the gripping unit into the open rotational position. A second arresting element is received in the latch housing such that it is movable between an unlocking position and a locking position. In the locking position, the second arresting element effects a blocking of the first arresting element to prevent rotation into the release position, in the unlocking position, the second arresting element permits such a movement of the first arresting element.Type: GrantFiled: February 2, 2016Date of Patent: March 26, 2019Assignee: emz-Hanauer GmbH & Co.
