風装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air blower with a rotating grill, and more particularly to an air blower with a rotating grill suitable for application to household electric fans and window ventilation fans.
」〔発明の背景〕
回転グリル付送風装置として知られている回転グリル付
扇風機は、たとえば、実開昭51−15641号公報に
示すように、本体ケースにファンと多数の静止翼を有す
る静止翼体を内蔵し、その前部に多数の偏向翼からなる
偏向翼体を有する回転グリルを装着している。[Background of the Invention] A rotating grill fan known as a rotating grill blower has a fan and a large number of stationary blades in a main body case, as shown in, for example, Japanese Utility Model Application Publication No. 15641/1983. It has a built-in body, and a rotating grille with a deflection wing body consisting of a large number of deflection wings is attached to the front part of the body.
静止翼体は、ファンによって生じたスパイラル形のねじ
れた風を加速して直進の風とする働きをし、この直進の
嵐はさらに回転グリルの偏向翼体により偏向されてサー
チライト形の一方向曲げの風となって拡散される。The stationary wing body accelerates the spiral-shaped twisted wind generated by the fan into a straight wind, and this straight storm is further deflected by the deflection wing body of the rotating grill to be directed in one direction in the shape of a searchlight. It becomes a wind of bending and spreads.
この構成の回転グリル付扇風機においては、ファンによ
って生じた風は、静止翼体で衝突の後、さらに、偏向翼
体に衝突するため、騒音が約5比旧と高い。In a fan with a rotating grille having this configuration, the wind generated by the fan collides with the stationary blade body and then further collides with the deflection blade body, so the noise level is about 5 times higher than that of the previous fan.

リル付送風装置のファンの送風による騒音対策を検討し
た結果、直進風を一方向曲げの風に同一箇所で重ね合わ
せれば、騒音が低下することが判明した。In addition, since the stationary blade bodies and the deflection blade bodies are provided at 8li positions, the entire fan body is thick and has the drawback of protruding into the room for a long time when attached to a wall. Therefore, as a result of investigating noise countermeasures using the fan of a rotating grille-equipped blower, it was found that noise could be reduced if straight air was superimposed on unidirectional wind at the same location.

本発明の目的は、ファンの送風による騒音を低減すると
ともに、薄形化を図った回転グリル付送風装置を提供す
ることにある。In particular, it was found that after generating a straight wind independently, if the straight wind was superimposed on a unidirectional wind at the same location, the noise level became more noticeable. Furthermore, it has been found that with the above-described configuration, the overall thickness of the rotary grill-equipped blower device can be naturally reduced. [Object of the Invention] An object of the present invention is to provide a rotating grille-equipped air blower that reduces noise caused by air blowing from a fan and is thinner.

定したことにある。The gist of the present invention is to provide a main body case having a suction port, a fan drive motor provided in the main case, a fan driven by the fan drive motor, and a fan drive motor provided in the main body case on the outflow side of the fan. A rotary grill made of synthetic resin that rotates at a lower speed than the fan, and a deflection blade body formed integrally with the rotary grill and consisting of a large number of deflection blades tilted in substantially the same direction. death,
A plurality of air conditioning blades extending radially from the center of rotation of the rotating grill are integrally formed with the deflection airfoil, and a fan-side end surface of the air conditioning airfoil protrudes from a fan-side end surface of the deflection airfoil. The length of the air conditioning blade in the air blowing direction is set to about 1 to 2 times the length of the deflection blade in the air blowing direction.

う。As a result, after the straight wind is generated independently, the straight wind is superimposed on the unidirectional wind at the same location, reducing noise. Moreover, the deflection blade body and the straightening blade body are located at almost the same place. Since they are formed so as to be overlapped, the overall thickness of the electric fan with rotating grill can be reduced. In the present invention, the wind regulating blade body refers to an assembly of vertical plate-shaped blades attached to a rotating grill and extending along the fan axis direction.

により拡散される。Due to the rotation of the fan 6, the speed Vc on the outflow side of the fan 6 is
The wind becomes a spiral-shaped twisted wind of os 8 (V: absolute speed, a: fan outflow angle). That is, with a twisted wind tilted by 8 degrees to the rut line of the fan 6, a wind with a velocity Vcos 8 (normally about 18 h/mjn) becomes effective. Then,
This wind is accelerated by the air conditioning blade 12 to become a wind at a speed V (usually about 22 plates/min), and becomes a straight wind at a speed V in the fan axis direction without almost losing the speed V. The wind whose speed reaches V in the air conditioning blade 12 is turned into a concentric searchlight-shaped one-way wind by the deflection blade 11 of the rotating grill 9 at the same speed V, and is diffused by the rotation of the rotating grill 9. .
この実施例による回転グリル付送風装置の騒音は約47
組となり、従来技術のものより約幻Bと大幅に低下し、
その結果静音の回転グリル付送風装置がえられた。The noise level of the blower with rotating grille according to this embodiment is approximately 47
The result is approximately B, which is significantly lower than that of the conventional technology.
As a result, a quiet air blower with a rotating grill was created.

In order to give the rotating grill a cool feeling, it is preferable to mold it from a transparent synthetic resin, and transparent ABS resin, transparent styrene resin, etc. may also be used. In addition, in the above embodiment, the fan drive motor 5 is protected by the guard 4.
What was installed is fan drive motor 5 and fan 6.

る。Here, the wind speed ratio V is the ratio between the wind speed obtained when the air conditioning blade 12 is provided on the rotary grill 9 having the deflection airfoil 11 and the wind speed obtained when the air conditioning airfoil 12 is not provided. In this case, as the rotary grill 9 without the air conditioning blades 12, the configuration of the rotating grill 9 shown in FIGS. 4 and 5 of the embodiment with the air conditioning blades 12 removed was used. Therefore, the size of the deflection wing body 11 is the upward projected length IQ. Further, the length L of the air conditioning blade 12 in the air blowing direction is varied in various ways with the front portion of the rotary grill 9 as a base point. As can be seen from FIG. 7, the wind regulating blade 12 is
When the length exceeds the length of the deflection blade 11, in other words, when the air conditioning blade 12 is made to protrude from the deflection airfoil 11, the wind speed ratio increases, and the length L of the air conditioning airfoil 12 in the air blowing direction increases. When the length exceeds twice the length in the blowing direction, the wind speed ratio rapidly decreases. Therefore, it can be said that the length L of the air conditioning blade 12 in the air blowing direction is preferably in a range of about 1 to 2 times the length of the deflection blade 11 in the air blowing direction. [Effects of the Invention] As described above, according to the present invention, the wind regulating blade is integrally formed with the biasing blade, and the fan-side end surface of the biasing blade is made to protrude from the fan-side end surface of the deflecting blade. Since the length of the air conditioning blade in the air direction is set to approximately 1 to 2 times the length of the deflection blade in the air direction, the noise caused by the air from the fan can be reduced and the design can be made thinner in the air direction. You can get an air blower with a rotating grill.
