Safety device for a hot water faucet for sanitary use and faucet, particularly thermostat, equipped with said safety element

Safety device for a hot water faucet for sanitary use, characterized in that it comprises:

• a casing (9) that delimits a receptacle (10) running all the way through said casing, with one (11) of the two ends (11, 12) of said receptacle, called the upstream end (11), which at least indirectly has means for hydraulically connecting to the outlet of a hot water faucet, and upstream from the other end (12), a so-called evacuation conduit (13) that opens out of the casing and hydraulically connects to a point intermediate to the two ends of the receptacle, giving the casing a T-shape,
• a seat (14) of a valve (15) delimited in the bore near its upstream end, and
• installed in the receptacle, beginning at the upstream end:
• a valve (15) with an elastic element (16) that stresses it toward its so-called closed position by applying it to the seat (14), and
• a so-called control rod (17) of the valve, connected to a control device (18) capable of pushing said valve toward the so-called open position, counteracting the action of the aforementioned elastic element, between the valve and the control device, this control rod locally comprising a fusible material (19) subject to the effect of the water temperature which, when it is subjected to a temperature higher than a predetermined temperature, melts so that the length of the control rod is reduced, thus causing the closing of the valve.
