Abstract: The present invention is related to a system for preparing and heating a food product within a cavity (8), said system comprising a self-cleaning device with a spraying device (10) for spraying a cleaning fluid into the cavity (8), in which a detergent holder (24) is placed. The detergent holder (24) is arranged on a framework or an accessing door (18) of the cavity (8), a multi-component cartridge (32) being received in the detergent holder (24), the detergent holder (24) being held in an inclined position at an angle (60) towards a center of the cavity (8), the multi-component cartridge (32) being sprayed on by spray jets (58) emerging from the spraying device (10) in a continuous or discontinuous manner.

Abstract: The invention relates to a cleaner cartridge for cleaning a soiled interior of an appliance, comprising: an integral housing for holding a treatment agent, at least one receptacle for connecting the cleaner cartridge to a water supply, wherein water can be introduced into the housing via the receptacle at a pressure which enables a treatment agent mixture to be sprayed, and at least one spray opening for spraying a treatment agent mixture, wherein the at least one spray opening is arranged as a rotation opening in the circumference-of the housing in such a way that rotation is imparted to the cleaner cartridge as a treatment agent mixture is sprayed. The invention furthermore relates to an appliance having a cleaner cartridge of this kind and to the use of a cleaner cartridge for cleaning appliances.
