Mechanism for a door of an electrical household appliance
A mechanism for a door of an electrical household appliance includes an opener for pushing open the door, wherein the opener includes an opener housing and, accommodated therein, a pusher arranged for a linear push-open movement and an electric motor drive for the pusher, and a latch for holding the door closed, wherein the latch includes a latch housing and, accommodated therein, at least one movably arranged closing element, which is provided for engagement, holding the door closed, with a counter-body approaching the closing element when the door is closed. The opener housing and the latch housing each have a coupling section which cooperate to mechanically couple the opener housing and the latch housing. Furthermore, the opener housing has at least one first fastening means designed to fasten the mechanism to the electrical household appliance when the coupling sections of the opener housing and the latch housing are mechanically coupled.
1 . A mechanism for a door of an electrical household appliance, comprising:
an opener configured to push open the door, the opener comprising an opener housing, a pusher accommodated in the opener housing, and a drive for the pusher,
a latch configured to hold the door closed, wherein the latch comprises a latch housing and accommodated therein, at least one movably arranged closing element, wherein the at least one closing element is configured to engage and hold the door closed, with a counter-body approaching the closing element when the door is closed,
wherein the latch is configured to be inserted into the opener housing, the opener housing and the latch housing each have a coupling section which co-operate to effect a mechanical coupling of the opener housing and the latch housing when the latch is inserted into the opener housing, and
wherein the opener housing comprises at least a first fastening structure which is adapted to attach the mechanism to the electrical household appliance when the coupling sections of the opener housing and the latch housing are mechanically coupled, wherein the latch housing is configured to be attached to a profile rail of the electrical household appliance via the first fastening structure.
2 . The mechanism according to claim 1 , wherein the drive is an electric motor drive.
3 . The mechanism according to claim 1 , wherein the opener housing and the latch housing are made of different materials.
4 . The mechanism according to claim 3 , wherein the opener housing comprises a reinforced material; and/or the latch housing comprises a low-friction material.
5 . The mechanism according to claim 4 , wherein the reinforced material comprises a glass fiber-reinforced material.
6 . The mechanism according to claim 4 , wherein the low-friction material comprises polyoxymethylene.
7 . The mechanism according to claim 1 , wherein at least one of the coupling sections comprises an arresting structure.
8 . The mechanism according to claim 7 , wherein the at least one of the coupling sections comprises an undercut, tab, catch, rail, and/or a clamping hook.
9 . The mechanism according to claim 1 , wherein
the opener housing comprises at least a second fastening structure adapted to attach the mechanism to the electrical household appliance when the coupling sections of the opener housing and the latch housing are mechanically coupled;
the latch housing has at least a third fastening structure adapted to fasten the mechanism to the electrical household appliance when the coupling sections of the opener housing and the latch housing are mechanically coupled;
the opener housing and the latch housing each have a further coupling section, which co-operate to effectuate a further mechanical coupling of the opener housing and the latch housing.
10 . The mechanism according to claim 1 , further comprising a door sensor disposed in the opener housing, wherein the latch or the opener comprises a movable element adapted to transmit a movement of the door to a section of the movable element cooperating with the door sensor when the door is closed.
11 . The mechanism according to claim 10 , wherein:
the movable element comprises a rocker arm and/or a slider; and
the section of the movable element cooperating with the door sensor is arranged in a region of the latch housing facing away from the door.
12 . The mechanism according to claim 10 , wherein the movable element comprises:
a section coupled to the closing element, which is set up to mechanically transmit a movement of the closing element to the section co-operating with the door sensor when the door is closed, or
a portion protruding from the latch housing adapted to mechanically transmit a movement of the door to the portion co-operating with the door sensor when the door is closed.
13 . The mechanism according to claim 1 , wherein:
the latch comprises no electrical and/or electronic components; and
only the opener comprises an electrical connection.
14 . The mechanism according to claim 1 , wherein the latch has a function for mechanically influencing at least one movement feature of the pusher.
15 . The mechanism according to claim 14 , wherein in having the function for mechanically influencing at least one movement feature of the pusher, the latch has a function for mechanically releasing a movement blocking of the pusher.
16 . The mechanism according to claim 1 , the pusher is configured for a linear push-open movement, and the drive comprises an electric motor drive.
