Claim:
A kitchen-range ( 18 ) of the type having a cooking top ( 8 ) comprising a surface on which at least one heating device ( 10 ) is arranged and on which a support means is arranged; the kitchen-range comprising: a first cleaning-element spraying assembly comprising at least one retractable spraying tower ( 5 ), housed in the cooking top ( 8 ), the retractable spraying tower comprising a piston ( 3 ) having spray orifices, said surface of the cooking top ( 8 ) having an opening ( 11 ) that allows said piston ( 3 ) to move upwards to a raised position elevationally above the surface and downwards to a position wherein a top of said piston is positioned level with or elevationally lower than the surface, said surface being inclined with respect to the horizontal plane, so that the elements sprayed by the retractable spraying tower ( 5 ) can flow to an outflow opening ( 17 ) connected to a circuit ( 12 , 13 , 15 ) that feeds cleaning elements back to said spraying assembly; a cleaning elements supply structure coupled with said circuit for connecting said circuit to an external source of cleaning elements, a cleaning elements drain structure coupled to the circuit for connecting the circuit to an external drain, and control structure for opening and closing the cleaning elements supply structure and the cleaning elements drain structure, enabling the entry and exit of the cleaning elements into and out of the circuit, and for turning on and off said cleaning elements supplying structure and the cleaning elements drain structure; and initiating and finishing the circulation of the cleaning elements through the circuit.
