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).

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.

Description

technical field [0001] The invention relates to the technical field of household electric fans, in particular to a nozzle-type heating and cooling household electric fan. Background technique [0002] Household electric fans are widely used in homes, offices, shops, hospitals, hotels and other places as a household appliance that uses a motor to drive the fan blades to rotate to achieve accelerated air circulation and cool and relieve heat. For a long time, household electric fans are mainly composed of fan heads, fan blades, net covers and control devices and other components. The fan head includes components such as the motor, front and rear end covers, and an oscillating air supply mechanism. Since the flow direction of the wind is parallel to the rotation axis of the fan blade, the limitation of this structure will inevitably affect the air circulation in the direction perpendicular to the rotation axis of the fan blade, thereby affecting its cooling effect.
