The invention discloses a nozzle type heating and cooling household electric fan. An induced draft fan and a frequency converter are arranged in an electric fan shell, and an air double filtration device and a water cooling and heating device are arranged on an air inlet pipe. The nozzle type heating and cooling household electric fan is characterized in that an air supply pipe is welded with the left end surface of an arc-shaped base plate through two flanges which are provided with seal plates and locked through bolts; multiple air supply ports which are distributed evenly are formed in the cambered surface of the arc-shaped base plate; spiral nozzles are arranged in the air supply ports respectively, and each spiral nozzle is provided with a cone-shaped spiral core, a spiral jetting slot, a tightening nut and a nozzle external thread; the jetting angles of the spiral nozzles are set to be ranging from 150 degrees to 170 degrees. After the power is turned on, the rotating speed and the air volume of the induced draft fan are regulated through the frequency converter, fresh air which is strictly filtered and conforms with the requirement of needed hot and cold temperature can be imported from the outside, winds which are in the layered cone-shaped interface flow direction and staggered with one another are jetted at a high speed from the air outlets of the spiral nozzles, and the ventilation is significantly strengthened, and the guarantee of human health is facilitated.
