Benefits of technology
[0022]1. Different from the prior-art air-guiding plate that only helps to form small and focused cylindrical cyclone, the disclosed air-guiding cover helps a fan to generate conical cyclone that covers widely and effectively promotes indoor air circulation.
[0023]2. The fan of the present invention is equipped with a heating device and capable of generating widely distributed warm air flow when working with the disclosed air-guiding cover. Thus the fan is a dual-purpose fan that is effective in both cooling and warming.
[0024]3. The fan of the present invention uses the heat-insulating tube to protect its motor from overheat caused by the heating device.
Problems solved by technology
However, the height of an electric fan also poses limitation to its active area, so it is also desired to make structural improvement on a fan's air-guiding cover so as to optimize the circulating efficiency of the fan.
However, the active area of wind such guided is relatively small and the strong eddy caused by the spiral cyclone tends to make people affected feel uncomfortable.
Hence, how to improve the existing air-guiding covers in terms of active area has become an issue for the related industry to address.

The present invention relates to provide an air-guiding cover, comprising: an inner ring; an outer ring being arranged around the inner ring and defining a windward plane between the outer ring and the inner ring; and a plurality of air-guiding fins being arranged in the inner ring. The air-guiding fins have an inclination with respect to a normal axis of the windward plane, and the inclination increases progressively as the air-guiding fins extend from the inner ring toward the outer ring.
Description
BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to an air-guiding cover and a fan having the air-guiding cover, wherein the fan using the air-guiding cover generates conical cyclone.[0003]2. Description of Related Art[0004]Electric fans have long been widely used in life to improve ventilation and cooling the ambient temperature or alternatively warm the ambient temperature when working with electric heaters. Electric fans are easy to install and applicable to various conditions, and thus have become a “must have” appliance in almost all households.[0005]There are many kinds of electric fans commercially available, including stand fans, ventilation fans and hanging fans. For maximizing its active area or coverage, an electric fan is usually equipped with an oscillating device that allows the fan to rotate from side to side while blowing. However, the height of an electric fan also poses limitation to its active area, so it is also desired to ma...
