IMPROVEMENTS INTRODUCED IN TEMPERATURE SWITCHING AND ADJUSTMENT DEVICES FOR HOME SHIRTS, TURNS AND ELECTRICAL WATER HEATERS

摘要

The set detailed here constitutes a technological evolution derived directly from the switching system described in depot pi 0405692-2. the power cable terminations derived from the junction box at the point of use of the building wiring do not undergo the usual vertical movement to which conventional apparatus showers and heaters are subjected, which exhibit such terminations attached to the movable bracket which moves with the movement of the central part of the diaphragm when opening or closing the record in the wall. This new module, which incorporates the actuation and temperature selection device, is formed by a fixed upper base, which contains the desired temperature selection system, and a substantially larger diameter heating support, which supports the switching the bare ends of the electric cables are fixed to static contacts attached to a pair of terminals that make up the fixed base, each of them being connected to a corresponding metal blade attached to this same support, the first being of rectilinear shape, with its opposite end. receiving a contact that acts as one of the energizing poles of the electrical resistance, when a water flow goes through the device and the temperature selector is set to one of the predicted heating levels. The second blade presents a rectilinear section that terminates in the central part of a trunk-circular sector, which externally tangents the curvature of a portion of the perimeter of this fixed base, both ends of this sector receiving respective electrical contacts, connected to the receiving terminal. the second cable derived from the building network. the heating support supports the diaphragm, the electrical resistance, the receptacle housing it, and three vertical metal rods whose ends fit into metal terminals housed in cavities of said receptacle, each terminal being in direct contact with the resistance wire. while the underside of the holder exhibits two opposing vertical projections whose ends are inserted into respective slots in the center of two guides at the top of the receptacle.
