A cleaning appliance and method for operating a cleaning appliance with a rotatable, non-ribbed drum for the pre-treatment and main treatment of textiles. The method comprises a step of supplying a feed signal for feeding a cleaning liquid into a suds container until a predetermined initial fill level is reached. A saturation action causes the textiles to be pre-treated to be saturated with the cleaning liquid. The method includes reading in a fill level signal that represents a fill level of the cleaning liquid, and supplying a further feed signal for feeding the cleaning liquid into the suds container until a target fill level is reached. A motion signal causes a rocking rhythm of the drum for pre-treating the textiles to be pre-treated. After the pre-treatment, an unlocking of a drum door takes place in order to allow additional textiles to be added for a main treatment of the textiles.

A sealing device for a sleeve of washing machines, provided internally with bearing units. The device is provided with a stationary first annular screen which integrally carries a first elastomeric element, a second annular rotating screen which integrally carries a second elastomeric element. The first and the second elastomeric elements face each other defining a first annular meatus (M), and a plurality of pairs of annular sealing lips (L1, L2) arranged inside the first annular meatus (M). The first sealing lip (L1) and the second sealing lip (L2) of the plurality of pairs of annular sealing lips (L1, L2) are substantially radially and axially superimposed and have predetermined axial dimensions to be radially and axially separated from each other and to define, inside the first annular meatus (M) and with the first and second sealing lips of the other pairs of annular sealing lips (L1, L2), a tortuous labyrinth (L).

A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

A drum washing machine, and a control method and a control apparatus for same are provided. The control method for the drum washing machine comprises the following steps: acquiring an average starting power of a drum in a starting process of the drum; acquiring a load range to which a current load of the drum belongs according to the average starting power; and setting a weighing protection velocity fluctuation threshold according to the load range to which the current load of the drum belongs. A value of the current load is obtained by using a correspondence between load with different weights and average starting powers. A weighing protection velocity fluctuation threshold is set according to the value of the current load to avoid the collision with the drum and non-dehydration in case of only one piece of clothing.

A home appliance, such as a laundry appliance, includes a component assembly with a sensor and a sensor-controlled component for operating the appliance, and a cover for housing the component assembly therein. The cover has an outer surface and an inner surface. The cover includes a functionalized superhydrophobic multi-layer coating on at least one of the outer surface and inner surface. The functionalized superhydrophobic coating prevents moisture from entering the component assembly and attacking sensors housed therein, and has a water contact angle thereon of at least 145 degrees.
