Disclosed is an internal circulation heating interactive combined ceiling electric appliance, which comprises an electric heater and an internal circulation component, the electric heater comprises a tank body, an infrared electro-thermal lamp, a wind passage, an wind wheel, a motor and a panel, the internal circulation component comprises a tank body and a panel, the wind passage of the electric heater is provided with an air change interface, and the air change interface is connected with a ventilating pipe which leads outdoors. The internal circulation heating interactive combined ceiling electric appliance is characterized in that the wind passage of the electric heater is further equipped with an internal circulation interface, and the internal circulation interface is connected with the tank body of the internal circulation component via the ventilation pipe. Because the wind passage of the electric heater is equipped with the air change interface and the internal circulation interface, the air change interface of the wind passage is connected with the ventilation pipe leading to outdoors, and the internal circulation interface of the wind passage is communicated with the internal circulation component via the ventilation pipe, the wind wheel driven by a bidirectional motor can realize ventilation and also can reuse the heat energy of the infrared electro-thermal lamp, which is not affected by radiation, and increases the heat efficiency.
