▎ 摘　　要

NOVELTY - The furnace has a furnace body (10) whose inside is provided with a graphene heating pipe (20), a control circuit board (30) and a control board (40). The control circuit board is electrically connected to the control board. The control board is electrically connected with the graphene heating tube. One end of the graphene heating pipe is provided with a water inlet (21). The other end of the graphene heating pipe is provided with a water outlet (22). A graphene heating wire is provided on the inner side of the graphene heating pipe. A normal temperature water is entered inside of the graphene heating pipe from the water inlet during use. The normal temperature water is heated by the graphene heating wire, and then output from the water outlet. USE - Directly-heated graphene energy-saving heating furnace for use in an electric appliance e.g. small sun and oil heater and PTC electric appliance. ADVANTAGE - The graphene heating pipe adopts efficient heating material heating speed and low cost, the pipeline connection transmission can quickly improve the indoor temperature, and it also can be connected with the bathroom device through pipeline to provide domestic hot water use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the internal structure of the directly-heated graphene energy-saving heating furnace. 10Graphene heating pipe 20Graphene heating pipe 21Water inlet 22Water outlet 30Control circuit board 31Display screen 32Control key 40Control plate
