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

Embodiment

[0020] Example: such as figure 1 , figure 2 As shown, the wall-mounted household electric fan provided with a nozzle includes an electric fan casing (10), an induced draft fan (5) and a frequency converter (9) are arranged inside the electric fan casing (10), and the electric fan casing ( 10) There is an air inlet (6) above the lower wall thickness, and a wire inlet (8) at the upper end. The power supply of the frequency converter (9) is connected to the power supply connected to the wire inlet (8), and the electric fan housing ( 10) Fix it on the wall through the wall-mounting hole (7).

[0021] The air outlet of the induced draft fan (5) is provided with an air supply pipe (11).

[0022] The main feature of the present invention is that the right end of the air supply pipe (11) is welded together with the flange I (12), and the flange II (14) is locked together by bolts, and the flange I (12) and flange II A sealing plate (13) is arranged between (14), and the right e...

Abstract

The invention discloses a wall-mounted type household electric fan with nozzles. A draught fan and a frequency converter are arranged in an electric fan shell; the wall-mounted type household electric fan is mainly characterized in that by arrangement of a sealing plate, an air supply pipe is welded with the end face of the left end of an arc-shaped base plate through two flanges locked through a bolt; a plurality of uniformly distributed air supply openings are formed in the arc surface of the arc-shaped base plate; spiral nozzles comprising conical spiral cores, spiral spraying slots, tightening nuts and nozzle external threads are respectively arranged in the air supply openings; the spraying angles of the spiral nozzles are set to be 150-170 degrees. The wall-mounted type household electric fan is hung on a wall; the frequency converter is used for adjusting the rotating speed and the air volume of the draught fan, so that the air spraying openings of the spiral nozzles can spray staggered air in the layered conical interface flowing direction, and the air ventilating, cooling and summer-heat relieving effects are obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of household electric fans, in particular to a wall-mounted household electric fan provided with nozzles. 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. Co...
