  • Patent number: 9380924
    Abstract: A dish washer comprises a carcass having a washing compartment accessible through an access opening, and a door attached to the carcass for closing the access opening. The door is bounded on its door side facing the washing compartment by a door inner wall, which provides sealing contact surfaces for a sealing arrangement attached to the carcass. A door latch comprises a latch head attached to the door and fixed relative to the latter, and a latch unit arranged on the carcass and having two latch arms which are movable relative to one another and embrace the latch head on both sides when the door is closed. On closing the door the latch head runs against the latch arms and pushes apart the latter from a relative rest position against spring force. The latch head rises preferably completely above the surface contour of the door inner wall.

  • Patent number: 9101259
    Abstract: A door lock for a dishwashing machine includes a lock housing, a pair of closing arms being held in and projecting from the lock housing and having free arm portions projecting from the lock housing that are deflectable relative to one another from a relative normal position in a first deflection direction counter to the action of a resetting spring arrangement, and a closing mouth, into which the free arm portions engage during closing of the door, having deflection surfaces encountered by the free arm portions during engagement into the closing mouth and which bring about a relative deflection of the free arm portions counter to the resetting action of the resetting spring arrangement, where the free arm portions during further engagement is move past the deflection surfaces and in so doing experience an at least partial resetting in the direction of their relative normal position.

  • Patent number: 8276951
    Abstract: A door-closing device for a domestic electrical appliance comprises a frame with an aperture for the introduction of a keeper. A closing unit is arranged on the frame such that when in a closing position, the closing unit holds the keeper for the purposed of keeping the door closed and, in an open position, releases said keeper for the purposed of opening the door, said closing unit, in the course of its transfer from the open position into the closing position, draws the keeper along with it. A closing spring arrangement acts upon the closing unit to draw the keeper along with said unit. A blocking element that is movable relative to the frame to block and unblock the movement of the closing unit.

  • Publication number: 20090072547
    Abstract: A door-closing device for a domestic electrical appliance comprises a frame (12) with an aperture (14) for the introduction of a keeper (16). Arranged on the frame so as to be movable, relative to the latter, is a closing unit (22) which, in a closing position, holds the keeper fast for the purpose of keeping the door closed and, in an open position, releases said keeper for the purpose of opening the door, said closing unit, in the course of its transfer from the open position into the closing position, drawing the keeper along with it along part of said keeper's path of movement. A closing spring arrangement which acts upon the closing unit supplies the force necessary for drawing the keeper along with said unit. The closing unit can be blocked by a blocking system (30) from moving out of the open position and into the closing position, it being possible to set aside the blocking of the closing unit by relative movement of said blocking system and closing unit.
