Device for a shower, consisting of a housing, a temperature controller, an LCD screen, a LED ring, two opening taps; a hot and cold water inlet; a three-way valve, a flowmeter connected to a pump; a thermostatic valve, a servomotor; and an integrated circuit card; method

A method for obtaining a water recirculating system, characterized in steps of:

• a) constructing a housing (1) that attaches to a shower wall and that constitutes a main body, adhering to its front part a temperature regulator (21), an LCD display (22), a LED ring (28), and two water valves (24 and 25);
• b) inserting a hot water inlet (2) and then connecting on the inside of the housing to a temperature sensor (6), connecting a three-way valve (7) having a first control knob (12) that is attached to a first servomotor (8) which rotates the first control knob (12) by 180°;
• c) at 180°, diverting water to a first pipe (9) connecting to a first flowmeter (10) connected to a recirculation pump (11);
• d) at 0°, diverting the water to a second pipe (14) connected to a hot water inlet (15) of a thermostatic valve (16);
• e) inserting a cold water inlet (4) to the housing and screwing it to a cold water inlet (17) of the thermostatic valve (16), connecting the cold water inlet (4) also to the recirculation pump (11);
• attaching a second control knob (18) of the thermostatic valve (16) to a second servomotor (20);
• f) connecting a pipe (19) of the thermostatic valve to a second flowmeter (23) and the two water valves (24 and 25);
• the components in steps a)-f) are interconnected to an integrated circuit board (29) by inserting it inside the housing (1);
• and connecting the integrated circuit board (29) to a switch (30).
