Device for dispensing at least one washing agent in a dishwashing machine
First Claim
1. A device for dispensing at least one washing agent in a dishwashing machine having a washing chamber which is closed by a door and in which there is mounted at least one spraying rotor for spraying a washing liquid;
- the dispensing device comprising a support body adapted to be mounted on the side of the door facing the washing chamber, in a position such that in the operation said body is periodically flushed, at least in part, by a flow of washing liquid emitted by said spraying rotor;
wherein in said support body there is incorporated an electrically conducting member whose electric capacitance with respect to earth is variable by the effect of the flow of washing liquid which periodically impinges onto said body;
detection and processing circuit means, coupled to earth, being connected to said conducting member and being predisposed for detecting the variations of the electric capacitance of said conducting member with respect to earth and for correlating in a predetermined manner said variations with the operation of said spraying rotor.

Abstract
The dispensing device includes a support body adapted to be mounted on the side of that door of the machine which is facing the washing chamber, in a position such that in the operation this body is periodically flushed, at least in part, by a flow of washing liquid emitted by at least one spraying rotor. In the support body there is incorporated an electrically conducting member whose electric capacitance with respect to earth is variable by the effect of the flow of washing liquid which periodically impinges onto the body; a detection and processing device being connected to the conducting member and being predisposed for detecting the variations of the electric capacitance of said conducting member with respect to earth and for correlating in a predetermined manner said variations with the operation of the spraying rotor.
