The invention discloses an intelligent gas stove and a range hood waste heat and wind energy collecting and utilizing device, and particularly relates to the field of energy recycling. The intelligentgas stove comprises a range hood, an air pipe, a wind driven generator, a gas cooking bench, a heat preservation water tank, a circulating water steel pipe, a storage battery and a single-chip microcomputer control system, wherein the heat preservation water tank is arranged on one side of the gas cooking bench and is connected with the gas cooking bench through the circulating water steel pipe.According to the intelligent gas stove, by collecting waste heat of a gas stove tray, cold water is heated and stored in the heat preservation water tank for later use, so that the use of fuel gas canbe reduced, and the environmental pollution is reduced; the smoke concentration is detected through a smoke concentration sensor and is controlled by a single-chip microcomputer control system, so that the rotating speed of the range hood can be automatically adjusted, and electric energy is reduced; and the waste wind generated by the range hood is utilized to drive the wind power generator to generate electricity, the obtained electric energy can be used for heat preservation of the water tank and charging a gas stove battery, a fuel gas meter battery and the like, so that the use of the disposable battery is reduced, and the pollution of mercury, lead and metal cadmium is reduced.
