▎ 摘　　要

NOVELTY - The smart bathtub has a bathtub main portion (1) whose outer surface is covered with a graphene heating film (3). A graphene hot water pipe (5) is hidden inside upper edge of main portion. An outer layer of graphene heating film is covered with a heat reflecting film (4). One end of graphene hot water pipe is connected to a water inlet pipe (7) and other end connected to a shower (6). A water temperature sensor (9) is set in an inner wall of main portion. The graphene heating film and the temperature sensor are electrically connected to an intelligent controller (10). USE - Smart bathtub. ADVANTAGE - Since the heat reflecting film is provided on the outer side of the graphite heating film, the loss of heat generated by the graphene film is avoided. Thus, the energy utilization rate is maximally improved. By fully using the high thermal conductivity of graphene, the water inside the bathtub main portion achieves a rapid warming and constant temperature, so as to ensure a new experience with domestic convenience. The smart bathtub has reasonable structure and design, low cost, convenient use, energy saving, and easy to popularize. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of the smart bathtub.
