Abstract

Electric water heating apparatus, characterized in that it is constituted by a cylindrical tubular body in one of whose mouths has a stop valve capable of sealing an outlet orifice communicated with an oblique tubular extension that defines the pipe, being threaded in the other embouchure a hollow main body provided with an end cover that incorporates a threaded radial extension for the anchoring of the assembly to the water pipe of the installation and a conical disc provided with perforations, passing the water to the interior of the main body, through the disc perforated and of an orifice provided in a membrane supported in a peripheral and internal recess of said main body and imprisoned by the cover, exiting to the outside through the spout; there is an electric resistance wound in a spiral on a cylindrical tubular support with two terminals for its connection by plug to the correspondingly located in each diametrically opposite points internal to the main body, which through its wall, emerge from the external periphery thereof, determining two terminals rows susceptible to contact with two movable terminals anchored to respective arched frogs conductive of a tilting lever in a "U" shape that surrounds the main body, whose connecting section, insulating, incorporates a coplanar rod to the branches and which crosses the wall of the said main body with an elastic coupling and sealing, this rod being connected to the membrane when passing through an orifice in the axial direction prolongation of a saucer fixed to the face of the membrane located downstream, and the ends of the branches of the lever in "U", anchored to the main body, constituting these anchor points are located in two electrical terminals connected to the power supply cables, all in order that when opening the stopcock, the pressure of water coming into the apparatus moves the membrane to tilt the lever in "U" and set contact the fixed and mobile terminals, closing the circuit and heating the resistance existing a control ring housed in an external recess of the main body capable of adopting two angular positions, one in which a radial projection thereof interferes with the displacement of the insulating section of the tilting lever to prevent the electric circuit and supply from closing, and another position in which said radial projection moves to allow the closing of the circular with the consequent heating of the water; the mass connection being provided at a point of the main body that extends axially inside the tubular support of the resistance and which contacts a pivot that emerges axially from the stopcock; the block being the resistance housed inside a bushing fixed to the main body and in an oil bath and the rocker lever and electrical terminals protected by an annular casing remaining.
