Device for installation on an inner circumferential surface of a washing machine drum

A device configured to be installed on an inner circumferential surface of a washing machine drum, the device comprising:

• a housing extending from a first end face to a second end face along a longitudinal direction, the housing defining a first receiving space and a second receiving space;
• a voltage source received in the second receiving space;
• at least one electrode received in the first receiving space and that extends from the first end face to the second end face, the at least one electrode being connected to a positive terminal of the voltage source;
• at least one inlet defined in the first end face and configured to receive a washing liquor into the device, the at least one inlet being in fluid communication with the at least one electrode in the first receiving space;
• and
• at least one outlet defined in the second end face and configured to discharge the washing liquor from the device, the at least one outlet being in fluid communication with the at least one electrode in the first receiving space,
• wherein an outer surface of the housing that at least partially defines the second receiving surface is convex such that, when the device is installed on the inner circumferential surface of the washing machine drum, the at least one inlet and the at least one outlet are directly above the inner circumferential surface of the washing machine drum.
