Problems solved by technology

Since the flow direction of the wind is parallel to the rotation axis of the fan blades, the limitations of this structure will inevitably affect the air circulation in the direction perpendicular to the rotation axis of the fan blades, thereby affecting its cooling effect

Abstract

The invention discloses a household ceiling fan provided with spray nozzles. An induced draft fan and a frequency converter are arranged in an electric fan shell; the household ceiling fan is mainly characterized in that an air supply pipe is provided with a sealing plate and two flanges locked by using a bolt are welded with a left end face of a cambered bottom plate, wherein a cambered surface of the cambered bottom plate is provided with a plurality of air supply holes which are uniformly distributed; spiral spray nozzles which comprise conical spiral cores, spiral spray grooves, rotary nuts and spray nozzle external threads are arranged in the air supply holes respectively; the jet angles of the spiral spray nozzles are set to be 150-170 degrees. The household ceiling fan is fixedly arranged on a ceiling; the rotation speed and the air volume of the induced draft fan are adjusted through the frequency converter, namely staggered wind in layered conical interface flow directions can be sprayed out downwards from air spray holes of the spiral spray nozzles at high speed, so ventilation and cooling and summer heat relieving effects are obviously enhanced.

Description

Technical field [0001] The present invention relates to the technical field of household electric fans, in particular to a household ceiling fan provided with a nozzle. Background technique [0002] As a household appliance that uses a motor to drive the fan blades to rotate to accelerate air circulation and provide cooling and relief from heat, household electric fans are widely used in homes, offices, shops, hospitals, hotels and other places. For a long time, household electric fans have mainly been composed of fan heads, blades, grilles, control devices and other components. The fan head includes components such as a 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 limitations 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 and heat-relieving ...
