Abstract
An improved shower-cabin comprising a base provided with a drain for evacuating waste water, and a heat recuperator incorporated into this base. The recuperator comprises a waste water tank connected to the cabin drain and a coil mounted in this tank. The heat of the waste water passing through the tank may be recovered for heating or pre-heating an incoming cold water flowing through the coil.
Claims13
In a shower-cabin comprising a bottom surface and a base provided with a drain for evacuating waste water, a heat recuperator incorporated into said base, said heat recuperator comprising a waste water tank provided with a coil mounted on a set of slightly inclined plates that are superimposed in a cascadelike arrangement, said tank having a top surface, an inlet connected to the cabin drain, an outlet and an overflow positioned at a predetermined level beyond which the water collected in the tank is evacuated, the top surface of said tank forming the bottom surface of said shower-cabin, whereby part of the heat contained in the waste water may be recovered and used to heat or pre-heat an incoming clean water flowing through said coil, the improvement wherein said waste water tank further comprises:
- a small lateral chamber having an inlet for receiving waste water different from the one coming from the shower and an outlet for said waste water, said small chamber being in communication with the tank via two lateral openings that respectively connect the upper and lower zones of said chambers and said tank to each other;
- and
- obturation means in the waste water outlet of the samll chamber.
In a shower-cabin comprising a bottom surface and a base provided with a drain for evacuating waste water, a heat recuperator incorporated into said base, said heat recuperator comprising a waste water tank provided with a coil mounted on a set of slightly inclined plates that are superimposed in a cascadelike arrangement, each plate having an upper surface provided with a spiral-shaped groove for receiving and holding a corresponding portion of the coil, said tank having a top surface, an inlet connected to the cabin drain, an outlet and an overflow positioned at a predetermined level beyond which the water collected in the tank is evacuated, the top surface of said tank forming the bottom surface of said shower-cabin, whereby part of the heat contained in the waste water may be recovered and used to heat or pre-heat an incoming clean water flowing through said coil, the improvement consisting in a plate, immediately positioned under the inlet of the tank, said plate having a reversed saucer shape, and other plates alternatively having non-reversed and reversed saucer shapes, each of said other plates having a central portion provided with an opening to allow waste water to flow in cascade toward the next plate down to the bottom of the tank and to give room to the overflow.
