Definitions
- the invention relates to an arrangement for a household appliance, with a laundry drum for receiving laundry items, and with an annular balancing device which is rotatably mounted on the laundry drum, wherein at least one locking element is formed on a radial circumference, in particular an outer periphery, a housing of the balancing device , which is engaged in a formed in a wall of the laundry drum latching opening.
- the invention also relates to a household appliance with such an arrangement, an imbalance compensation device for a laundry drum of a household appliance and a method for attaching an imbalance compensation device to a laundry drum of a household appliance.
- an annular unbalance compensating device also known as a "ball balancer" - to the laundry drum an annular hollow housing in which a balancing mass is provided, for example in the form of a plurality of spherical compensating elements.
- This balancing mass is movably mounted in the interior of the housing and during operation of the washing machine tends to contact one of the unbalanced masses Diameter of the Wash basket - to move opposite side, thus creating a counterweight for the imbalance mass and consequently overall balance.
- the interest is directed to the attachment of such an imbalance compensation device to a laundry drum.
- Such methods are already known from the prior art in various embodiments.
- the document US 201 1/0203325 A1 describes a solution in which the housing of the imbalance compensation device is injection-molded onto an axial end wall of the laundry drum.
- the unbalance compensation device by means of screws to the laundry drum.
- a screw connection between an imbalance compensation device and a laundry drum is proposed, for example, in EP 2 154 285 A1.
- the invention is based on an arrangement as described in KR 10 2008 037 420 A and in which an imbalance compensation device is fixed via a latching connection to a laundry drum.
- locking elements are formed on a radial outer circumference of a housing of the unbalance compensation device, which are engaged in corresponding latching openings of the laundry drum.
- the latching elements lie axially against an edge delimiting the respective latch opening, so that a positive connection is formed in the axial direction.
- Such a latching connection has in particular the disadvantage that it may come to a release of the latching connection.
- the latching elements of the imbalance compensation device can be released from the respective latching openings, and it can come to a total fall out of the imbalance compensation device from the axial recess of the laundry drum.
- This object is achieved by an arrangement by a household appliance, by an imbalance compensation device and by a method having the features according to the respective independent claims.
- Advantageous embodiments of the invention are the subject of the dependent claims, the description and the figures.
