Abstract
The utility model discloses an improved electric fan whose front net cover is formed by the wind dividing plates in actinoid distribution. The utility model can divide the concentrated air current blown by fan blades into the fan-shaped air current in order to provide the soft and comfortable feeling to people.
Description
The utility model is to belong to household electronic products.
The air-flow that electric fan blew out of Chu Shouing is all more concentrated in the market, is one stronger air-flow continuously.It is too strong directly to blow on human body wind-force.Of a specified duration is unhelpful to human body, and the electric fan of band oscillating mechanism make the people feel wind rapid it, wind goes wink to die, there is not the soft comfortable sense of natural wind, the arrangements for speed regulation of these electric fans (current-limiting reactor formula arrangements for speed regulation especially, big city reduces the power factor of motor, and can influence the quality of electrical network.
The guard of above-mentioned electric fan only plays the safety protection effect, does not still play the effect that changes the air-flow that electric fan blew out.
The rotary blade fan of Xing Qiing these years relies on slowly running of the front mesh enclosure that has the inclination blade-rotating.Improve the air-flow that fan blade blew out, given soft comfortable sense.But this fan structure is complicated, and the air-flow that is blown out can not reach place far away, thereby has deficiency.
The purpose of this utility model provides a kind of improved electric fan, and it blows out the soft comfortable sense that air-flow has a burst of natural wind.
Another purpose of the present utility model is in order to change the machine-made appearance of present electric fan guard, a kind of electric fan guard of pattern novelty to be provided.
The utility model is that shape and the structure by the front mesh enclosure that changes electric fan realizes.Its preceding fan housing is made up of the split-wind plate that is radiation distribution or symmetrical tilt distribution, rely on these split-wind plates that the air-flow of concentrating that flabellum blew out is dispersed into a flow area that is fan-shaped distribution, give soft comfortable sense.
The described radiation degree that is the split-wind plate of radiation distribution can be fix also adjustable; A split-wind plate i.e. category is similar to the straight plate of blind shaped, also one group of concentric plectane of external-open gradually.Split-wind plate industrial chemicals injection molded, also the available metal plate is made.
For avoiding producing eddy current, the radiation degree (or inclined degree) of split-wind plate is unsuitable excessive; Split-wind plate is also far away from fan blade as far as possible.
Also can be at this guard of the online installation of the already used electric fan of people at present.
According to the peculiar structure of this guard, can make outward appearance with handicraft article character.
Also can on the already used electric fan of people this guard be installed at present.
This electric fan since can by reconcile split-wind plate and motor shaft to angle reconcile the size of electric fan air quantity.Thereby can so just save the inductance element that wastes electric energy without the alignment circuit of motor, and improved motor power factor, saved electric energy, improved power grid quality.
Below in conjunction with embodiment and accompanying drawing the present invention is described in further details.
Fig. 1 is the schematic representation of a kind of concrete structure of the present utility model.
Fig. 2 is the sectional view along A-A line among Fig. 1.
Fig. 3 is the schematic representation of another kind of concrete structure of the present utility model.
Fig. 4 is the sectional view along the B-B line among Fig. 3.
In conjunction with Fig. 2, split-wind plate＜1〉be installed on fan fan blade＜3〉front end.Split-wind plate＜1〉with fan blade＜3 distance to try one's best far.Can avoid producing eddy current like this.Among the figure＜2 be to connect gusset, and it and adjustable knob＜4〉link, by knob＜4〉can reconcile split-wind plate＜1〉and the angle＜α of airflow direction.Split-wind plate＜1〉with the angle＜α of airflow direction also fixing.
When fan blade＜3〉when rotation, the air-flow that it produced is by split-wind plate＜1〉time, just be dispersed into a zone of almost fan, both sides in this zone (a), (c) Duan wind-force is more weak.And the wind-force that intermediate section (b) is located is stronger.Like this when electric fan oscillating, blow to air-flow into body and obviously be more weak before this (a) and locate (or＜c〉locate), be stronger＜b then locate.Last is again more weak＜c〉locate.Pass through knob＜4 will for so the soft comfortable sensation of a kind of approximate natural wind of people 〉, also can adjust the effect degree of branch wind.Separate with the whole of speed that replaces fan electromotor.Thereby can make fan electromotor be always operating at last operation point, save electric energy.
Claims (2)
1. wind division type electric fan, substantially by motor (7), fan blade (3), front mesh enclosure (5), rear net cover (6), oscillating mechanism, base support part (8) is formed, and it is characterized in that front mesh enclosure (5) distributes or is that the split-wind plate (1) that tilts to be symmetrically distributed forms by being radiation.
2. electric fan as claimed in claim 1 is characterized in that the split-wind plate (1) and the angle (α) of airflow direction are reconcilable.
