The electric wires are connected to the motor 3; an air inlet group 24 is provided on the circumferential side wall of the ventilation hood 2 to connect to the hood cavity 21; generally, the integrated suspended ceiling multifunctional ceiling fan is turned on in summer. When the integrated suspended ceiling multifunctional ceiling fan is working, the control circuit board 5 is powered on, and the control circuit board 5 supplies power to the motor 3. The motor 3 drives the impeller 4 to rotate and draw air. The wind enters the hood cavity 21 from the air inlet group 24, and then blows out from the air outlet grille 23 to ventilate and cool people under / near the integrated suspended ceiling multifunctional ceiling fan; it can also generate air flow ventilation in the room; the main technical improvement of this product is that an electric heating lamp 6 is provided on one side of the bottom of the ventilation hood 2, and the electric heating lamp 6 is connected to the control circuit board 5 through electric wires. The circuit board 5 is connected; the electric heating lamp 6 heats the nearby space when it is working; in autumn and winter, the fan cooling function is basically not turned on, and the electric heating lamp 6 is mainly turned on, so that the indoor space can be heated to play a heating role; this product can ventilate and cool, and can also heat, and has dual functions of cooling and heating, which improves the utilization rate of the product and can be used as an electric heater; when the electric heating lamp 6 is turned on, in order to circulate and diffuse the hot air, the low-power fan function can be turned on to circulate the air, so that the hot air circulates with the wind, which can play a good role in heat diffusion and increase the heating area; this product can be installed in the office, living room, bathroom, bedroom, dining room, etc. The electric heating lamp and the fan are set as one, hung on the floor ceiling or ceiling bracket, do not occupy the storage space of the ground or the shelf, and are easy to use.

The lighting of the illuminating lamp 7 is controlled by the control circuit board 5.

[0020] The lighting lamp 7 is located at the outer periphery of the air outlet grille 23 and is set at a suitable position.

[0021] The top cover 1 and ventilation hood 2 are square in shape as a whole, and their length and width are generally 60 cm, which can be connected and installed with the gusset holes of the ceiling bracket; the air outlet grille 23 is arranged in a circular ring and is adapted for use with the round impeller 4; an electric heating lamp 6 is arranged at a corner on one side of the bottom of the ventilation hood 2, and there is sufficient space in this place, which is suitable for installing the electric heating lamp 6 to better utilize the remaining space.

[0022] Electric heating lamps 6 are respectively arranged at the two side corners of the bottom of the ventilation hood 2, with a total of two electric heating lamps 6.

[0023] The four side walls of the ventilation hood 2 are all provided with air inlet holes 24 connected to the hood cavity 21, so as to increase the number of holes and the air inlet volume and reduce wind resistance.

[0024] A raised air guide ring 27 is extended around the outer circumference of the air outlet grille 23 at the bottom of the cover cavity 21. The air outlet grille 23 is located in the air guide ring 27. The motor 3 and the impeller 4 are arranged in the air guide ring 27. Since the height of the impeller 4 is almost the same as the height of the air inlet hole group 24, an air guide ring 27 is provided to prevent the incoming air from mixing during exhaust and to form a smooth flow path for the incoming air.
