Claim Text:
1. A cleaning apparatus for a kitchen cooking device having a cooking space, which is delimited by at least one wall, and at least one outlet opening for a liquid, said apparatus comprising, in combination: a ventilation fan associated with the cooking space and a drive motor for the ventilation fan; a collecting tank which at least temporarily collects the liquid that exits the cooking space via the outlet opening; a supply line for at least one of fresh water and a cleaning fluid, the supply of fresh water and cleaning fluid being controlled by a valve provided in the supply line; a circulating pump at the collecting tank for the liquid sitting in the collecting tank; a circulation line by which the liquid sitting in the collecting tank and conveyed by the circulating pump can be transported to the cooking space; a drain line for discharging the liquid that exits from the cooking space; a drain pump arranged at the collecting tank in addition to the circulating pump, via which the liquid sitting in the collecting tank can be conveyed actively into a discharge line together with solids that may be contained therein; a riser arranged between the collecting tank and a drain pipe, wherein the drain pump is dimensioned such that the liquid sitting in the collecting tank and the solids therein are removed via the riser; and a non-return valve arranged in the riser that prevents a back flow of the liquid that is located in the riser into the collecting tank, wherein a conveyor wheel of the drain pump is provided beneath a conveyor wheel of the circulating pump relative to the horizontal installation position of the cleaning apparatus, and further comprising a distributed power source for powering the drive motor for the ventilation fan, a circulating pump motor driving the conveyor wheel of the circulating pump and a drain pump motor for powering driving the conveyor wheel of the drain pump, said distributed power source having a first inverted rectifier for the drive motor of the ventilation fan, a second inverted rectifier for the circulating pump motor and a third inverted rectifier for the drain pump motor, as well as a common supply unit for the first, second and third inverted rectifiers, wherein the common supply unit includes a rectifier and an intermediate circuit.
