Abstract

The present invention relates to a device for detecting and preventing leaks of water from domestic appliances used for washing objects. Two terminals of the sensor 1 are connected to comparator means consisting of an electrical circuit 2 of a known type, consisting of a differential circuit with a high input impedance, an internal reference resistance of which is compared at each instant with the resistance between the aforesaid two metallic elements 1' of the sensor element 1. If the resistance between the aforesaid two metallic elements becomes smaller than the aforesaid internal reference resistance of the electrical circuit 2 because of the presence of water, the electrical circuit 2 causes the closing and opening, respectively, of two switches or electrical contacts 3 and 4, which are normally, i.e. in conditions in which no water is in contact with the metallic elements 1' of the sensor element 1, open and closed respectively. These electrical contacts 3 and 4 are associated with a relay 5 or, alternatively, with a solid state switch element 6, of a known type, represented by a broken line, and are located, respectively, in the electrical power supply line of a cut-off element consisting of a solenoid valve 7 fitted in a water supply line leading to a domestic appliance 8, and in an electrical power supply line of the domestic appliance 8. <IMAGE>
