Problems solved by technology

[0003] For existing bladeless fans, if the air outlet direction is the front and rear direction, the air inlet is usually arranged on the left or right surface of the casing, so that the air inlet direction is perpendicular to the air outlet direction, which affects the smoothness of the air inlet , it is also easy to increase the thickness of the bladeless fan in the air outlet direction, resulting in a larger volume of the bladeless fan and a larger space occupied

Abstract

The invention relates to the technical field of fans, in particular to a bladeless fan. The bladeless fan provided by the invention comprises a shell, a wind duct structure, a wind inlet formed in the shell, and a wind wheel arranged in the shell. The wind duct structure comprises a wind ring portion with an annular wind outlet gap, and air is driven by the wind wheel to enter the wind duct structure from the wind inlet and flow out from the annular wind outlet gap. The bladeless fan is characterized in that the wind inlet and the wind ring portion are arranged on the shell in the mode that the central axis of the wind inlet is roughly perpendicular to the central axis of the wind ring portion, so that the wind inlet direction is roughly parallel to the air outlet direction; and the air inlet direction refers to the direction in which air enters into the shell from the wind inlet, and the air outlet direction refers to the direction in which air flows out from the annular wind outlet gap. Since the wind inlet direction is roughly parallel to the air outlet direction, the wind inlet smoothness of the bladeless fan can be improved, and the wind feeding efficiency of the bladeless fan is improved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a bladeless fan. Background technique [0002] The bladeless fan is also called air doubling machine, which uses the impeller to inhale air from the air inlet at the bottom and drive the air to flow out from the annular air outlet gap on the wind ring part. The air flowing out from the annular air outlet gap can entrain the wind ring The air at the end flows forward together, amplifying the airflow, and finally forming a natural and continuous cool breeze. Compared with the bladed fan, the bladeless fan has no exposed fan blades, so not only can the problem of dust accumulation on the fan blades be effectively avoided, but also it is safer to use. [0003] For existing bladeless fans, if the air outlet direction is the front and rear direction, the air inlet is usually arranged on the left or right surface of the casing, so that the air inlet direction is perpendicular to the air o...
