By removing the claws 6b of the cosmetic grill 6 from the claws 1e of the main body 1, as shown in FIG. 11, the cosmetic grill 6 is opened and closed in the rotational direction about the bearing 6a and the shaft 1d.
図１０に示すように、化粧グリル６の吹き出し部分には、第２の突起であるリブ状の突起６ｅが設けられている。突起６ｅは、長手方向において凸部と凹部とが連なった形状である。また、図６に示すように、本体１にも吹き出し部分に第１の突起であるリブ状の突起１ｇが設けられている。突起１ｇは、長手方向において凸部と凹部とが連なった形状である。突起１ｇは、高電圧ユニット５の周囲に設けられている。突起６ｅと突起１ｇとは、同じ形状及び同じ大きさであり、凸部と凹部とのピッチも同じである。図７に示すように、突起１ｇの凸部と突起６ｅの凹部とが突起１ｇ及び突起６ｅの突出方向に沿って対向し、突起１ｇの凹部と突起６ｅの凸部とが突起１ｇ及び突起６ｅの突出方向に沿って対向する。したがって、突起１ｇと突起６ｅとの間の隙間１７は、蛇行形状となっている。ここで、蛇行形状の隙間とは、長手方向に沿って見た場合に、隙間を挟んで対峙する二つの部材の一方が凸で他方が凹の部分と、一方が凹で他方が凸の部分とが交互に出現することを意味する。すなわち、実施の形態１において隙間１７が蛇行形状であることは、隙間１７を長手方向に沿って見た場合に、突起１ｇの凸部と突起６ｅの凹部とが対峙する部分と突起１ｇの凹部と突起６ｅの凸部が対峙する部分とが交互に出現することを意味する。蛇行形状の例には、正弦波形状、三角波形状、パルス波形状及びミアンダ形状を挙げることができるが、これらの形状に限定されない。 As shown in FIG. 10, a rib-like protrusion 6e, which is a second protrusion, is provided at the blowout portion of the makeup grill 6. The protrusion 6e has a shape in which a convex portion and a concave portion are connected in the longitudinal direction. Further, as shown in FIG. 6, the main body 1 is also provided with a rib-like protrusion 1 g which is a first protrusion in the blowout portion. The protrusion 1 g has a shape in which a convex portion and a concave portion are connected in the longitudinal direction. The protrusion 1 g is provided around the high voltage unit 5. The protrusions 6e and the protrusions 1g have the same shape and the same size, and the pitch of the projections and the recesses is also the same. As shown in FIG. 7, the protrusion of the protrusion 1g and the recess of the protrusion 6e are opposed along the protrusion direction of the protrusion 1g and the protrusion 6e, and the recess of the protrusion 1g and the protrusion of the protrusion 6e are the protrusion 1g and the protrusion 6e. Opposite along the direction of protrusion of Therefore, the gap 17 between the protrusion 1 g and the protrusion 6 e has a meandering shape. Here, in the meandering gap, when viewed along the longitudinal direction, one of the two members facing each other across the gap is a convex portion, the other is a concave portion, and one is a concave portion and the other is a convex portion. It means that and appear alternately. That is, in the first embodiment, the gap 17 has a meandering shape because the protrusion of the protrusion 1 g and the recess of the protrusion 6 e face each other when the gap 17 is viewed along the longitudinal direction, and the recess of the protrusion 1 g And the portion of the protrusion 6e facing each other appear alternately. Examples of meandering shapes may include, but are not limited to, sinusoidal shapes, triangular shapes, pulse shapes and meander shapes.
隙間１７の幅は概ね一定に保たれている。吹き出し部分の隙間１７は、異物を挿入できない幅となっている。隙間１７は、電気用品安全法に定められた充電部からの保護の試験に用いる試験指の直径よりも小さい１２ｍｍ未満とすることで、隙間１７に指が挿入されることを防止できる。なお、隙間１７を１２ｍｍ未満とした場合には、ＩＥＣ（International Electrotechnical Commission）とも称される国際電機標準会議の規格であるＩＥＣ６０５２９の保護等級２級に相当する。隙間１７の幅は１２ｍｍ未満に限定されない。 The width of the gap 17 is kept approximately constant. The gap 17 at the blowout portion has a width at which no foreign object can be inserted. The gap 17 can be prevented from being inserted into the gap 17 by setting the gap 17 to less than 12 mm smaller than the diameter of the test finger used for the test of protection from the charging part defined in the Electrical Appliances and Materials Safety Act. When the gap 17 is less than 12 mm, it corresponds to the second grade of protection of the IEC 60529, which is a standard of the International Electrotechnical Commission, also referred to as the IEC (International Electrotechnical Commission). The width of the gap 17 is not limited to less than 12 mm.

実施の形態１に係る送風装置は、化粧グリル６の一方の半面から吸い込み、他方の半面から吹き出す構造のため、吸い込み側１４と吹き出し側１５とを区切る必要がある。図１０に示すように、化粧グリル６は、背面に吸い込み吹き出し区切りリブ６ｃを備えている。また、図６に示すように、本体１は、吸い込み吹き出し区切りリブ１ｆが２箇所に設けられている。図８に示すように、ファンケーシング４には、吸い込み側１４と吹き出し側１５とを区切る吸い込み吹き出し区切りリブ４ｃが設けられている。送風装置の吸い込み及び吹き出し方向は、図６に矢印で示すようにそれぞれ３方向である。 In the blower according to the first embodiment, it is necessary to separate the suction side 14 and the blowout side 15 because the air is sucked from one half of the cosmetic grill 6 and blown out from the other half. As shown in FIG. 10, the makeup grill 6 is provided with a suction blowout partition rib 6c on the back surface. Further, as shown in FIG. 6, the main body 1 is provided with suction blowout dividing ribs 1f at two places. As shown in FIG. 8, the fan casing 4 is provided with a suction blowout dividing rib 4 c that divides the suction side 14 and the blowout side 15.

FIG. 15 is a perspective view showing an internal configuration of the high voltage unit of the air blower according to the first embodiment. FIG. 16 is a circuit diagram of the high voltage unit according to the first embodiment. The high voltage unit 5 has a discharge electrode 11, a counter electrode 12 and an outer shell 18. The outer shell 18 is made of resin. The discharge electrode 11 is a wire-like electric conductor having strength. The counter electrode 12 is an electrical conductor. Although a material of the discharge electrode 11 can be exemplified by tungsten, it is not limited thereto. As a material of the counter electrode 12, although stainless steel can be illustrated, it is not limited to this. The discharge electrode 11 and the counter electrode 12 are made of a material that does not rust with water so that they can be washed with water when dust adheres. As shown in FIG. 16, the high voltage unit 5 has a structure in which the counter electrode 12 is disposed so as to sandwich the discharge electrode 11 from both sides. A high voltage is applied between the voltage-side discharge electrode 11 and the ground-side counter electrode 12 to generate a discharge and an electric field space.
図１７は、実施の形態１に係る送風装置の変形例を示す図である。実施の形態１に係る送風装置は、多翼式送風機２の後流側に高電圧ユニット５を配置し、本体１の吹き出し部分に波状の突起１ｇを設け、化粧グリル６の吹き出し部分に波状の突起６ｅを設けているが、図１７に示すように、モータ７の駆動軸が取付面１６と平行になるように多翼式送風機２を設置する場合には、多翼式送風機２の前流側に高電圧ユニット５を配置した方が空間効率的に有利である。高電圧ユニット５を多翼式送風機２の前流側に配置する場合には、本体１の吸い込み側に突起１ｇを設け、化粧グリル６の吸い込み側に突起６ｅを設けてもよい。 FIG. 17 is a view showing a modification of the blower according to the first embodiment. In the air blower according to the first embodiment, the high voltage unit 5 is disposed on the downstream side of the multi-blade fan 2, and a wavelike protrusion 1 g is provided on the blowout part of the main body 1. In the case where the multi-blade fan 2 is installed so that the drive shaft of the motor 7 becomes parallel to the mounting surface 16 as shown in FIG. It is more space efficient to arrange the high voltage unit 5 on the side. When the high voltage unit 5 is disposed on the upstream side of the multi-blade fan 2, the protrusion 1 g may be provided on the suction side of the main body 1 and the protrusion 6 e may be provided on the suction side of the cosmetic grill 6.
実施の形態１に係る送風装置は、隙間１７が蛇行形状であるため、隙間が直線状である場合と比較して、単位面積当たりの隙間１７の面積を大きくすることができる。したがって、本体１の大きさが同じであるならば、隙間１７が占める面積は、隙間が直線状である場合よりも大きくなる。したがって、実施の形態１に係る送風装置は、空気清浄装置である高電圧ユニット５を備えつつ本体１の大型化を抑え、かつ低騒音を実現することができる。 In the blower according to the first embodiment, since the gap 17 has a serpentine shape, the area of the gap 17 per unit area can be increased as compared with the case where the gap is linear. Therefore, if the size of the main body 1 is the same, the area occupied by the gap 17 is larger than in the case where the gap is linear. Therefore, the blower according to the first embodiment can suppress increase in size of the main body 1 and realize low noise while being provided with the high voltage unit 5 that is an air purification device.
以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configuration shown in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and one of the configurations is possible within the scope of the present invention.
