<p>A bath water preheating and energy-saving device for barbershop, includes a box (1), a heat-exchanger (4) on the bottom of the box (1), a water funnel (3) secured in the upper portion of the box (1), a tap water inlet (8), a tap water outlet (6), a heat-exchanger's waste hot water inlet (5) and a waste water outlet (9). The inlets/outlets (5, 6, 8, 9) are respectively connected to the heat-exchanger (4). The heat-exchanger (4) is connected to the water funnel (3) through the heat-exchanger's waste hot water inlet (5). A hair filter (2) is provided between the water funnel (3) and the heat-exchanger's waste hot water inlet (5). A waste hot water inlet (10) is provided in the upper side wall of the water funnel (3). The waste hot water inlet (10) is connected to a tub discharging port, and is positioned below the tub discharging port. Due to the gravity, waste hot water flows into the energy-saving device, exchanges heat with the tap water, and then flows out.</p> |
