Abstract

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.

Example Embodiment

[0029] Example: such as figure 1 , figure 2 As shown, the nozzle-type heating and cooling household electric fan includes an electric fan housing (15) and a wire inlet (13). The electric fan housing (15) is provided with an induced draft fan (12) and a frequency converter (14), An air inlet pipe (11) is provided above the lower wall thickness of the electric fan housing (15), and a wire inlet (13) is provided on the upper end. The power supply of the frequency converter (14) is connected to the power supply of the wire inlet (13) .

[0030] The air inlet pipe (11) introduces fresh air from the outside through the extension pipe. The air inlet pipe (11) is provided with an air double filter device along the radial direction. The air double filter device is sealed by a dustproof, waterproof and breathable membrane into a cylindrical shape. The grid-shaped water storage frame (8), and the cylindrical grid-shaped water storage frame (8) is filled with water (9).

[0031] The upper and lower ends of the cylindrical grid-shaped water storage frame (8) are respectively provided with flanges Ⅲ (7) with bolts, and the upper and lower two sides of the cylindrical grid-shaped water storage frame (8) are connected through flange Ⅲ (7). The end is fixedly connected to the air inlet pipe (11).

[0032] One side of the cylindrical grid-shaped water storage frame (8) is communicated with the inlet pipe (6) of the water cooling and heating device (5), and the other side is communicated with the outlet pipe (10), and the outlet pipe (10) is connected to the water cooling device. The heating device (5) is connected to form a loop.

[0033] The air outlet of the induced draft fan (12) is provided with an air supply pipe (16).

[0034] The main feature of the present invention is that the right end of the air supply pipe (16) is welded to flange I (17), and flange II (19) is locked together by bolts. Flange I (17) and flange II A sealing plate (18) is arranged between (19), and the right end face of flange II (19) is welded to the left end face of the arc-shaped bottom plate (1).

[0035] Three uniformly distributed air supply ports (3) with internal threads are arranged on the arc surface of the arc-shaped bottom plate (1).

[0036] The air supply port (3) is provided with a spiral nozzle (4) and a spiral nozzle (4) including a tapered spiral core (20), a spiral spray groove (21), a tightening nut (22) and a nozzle external thread (23). The air outlet of the air outlet passes through the circular hole of the arc-shaped nozzle cover (2) corresponding to the air outlet.

[0037] The spray angle range of the spiral nozzle (4) is set to 170°.
