Improvements in the grounding system of electric devices of heating water.

摘要

"Improvements in the grounding system of electric heating instant water".This patent for improvements in the grounding system of heaters, faucets, showers and electric showers.Providing a substantial reduction in the level of leakage current discharged by the driver of the earth, making fully feasible to use a differential circuit breaker (DR).The novelty consists of an apparatus whose housing (1) has a projection (16) whose inner cavity communicates with the orifice mounting (17) of the core of water inlet and receives the free end uMa connection (18) fixed by simple mechanical fitting, and whose opposite side is connected to a tube (19) or hose flexible thin wall.The tube and the connection made of thermoplastic material, the opposite end of the tube being free and open, may be positioned within the heating chamber (2),The wall (3) of the housing (1) can be endowed with a set of fine radial projections (20) which serve as guides for the tube (19).While the upper wall of the internal cavity of the projection (16) has a mounting hole crossed by a segment of wire conductor (21) fitted with an insulating cover.Said conductor extending along the connection (18) and the tubular element (19),With the passage after the opening of this tube having a warp (22) which derives a vertical segment (23) which ascends to near the top (9) of the housing (1),Following two successful for a stretch folds downward (24) positioned in the tube syphon (25) integrated to the separator (4), and its lower end (26) devoid of insulating layer.The same occurring with the opposite end (27) of the conductor, to the external part of the device.While the passage (21) disposed along the passage of the core of entry has a small length (29) also devoid of cover.The tubular element (19) may be adapted to the housing (1a) of a device equipped with a sensor (30) positioned inside the core stream inlet (5) and connected to an external terminal (3)1), said component having a connection (32) in which the ring tab (33) fits in the hole of the water inlet, getting stuck through adhesive.
