Description

イオン発生機Ion generator
　本発明は、筐体に設けられた吹出口からイオンを含む空気を吹出すイオン発生機に関する。 This invention relates to the ion generator which blows off the air containing ion from the blower outlet provided in the housing | casing.
　従来より、床面に設置されるイオン発生機が開発されている。床面設置型のイオン発生機が開示された文献として、たとえば特開平１１－１６７９７５号公報（特許文献１）を挙げることができる。 Conventionally, ion generators installed on the floor have been developed. As a document disclosing a floor-mounted ion generator, for example, JP-A-11-167975 (Patent Document 1) can be cited.
　特許文献１に開示のイオン発生機は、筐体内に収容された水槽内に貯留された水を利用してマイナスイオンを発生させ、筐体の底部に設けられた吸込口から吸い込んだ空気に当該マイナスイオンを付与する。マイナスイオンを付与された空気が、筐体の上面に設けられた吹出口から外部に吹出される。 The ion generator disclosed in Patent Document 1 generates negative ions using water stored in a water tank housed in a housing, and applies the air sucked from a suction port provided at the bottom of the housing. Gives negative ions. Air to which negative ions are applied is blown out through a blowout port provided on the upper surface of the housing.
特開平１１－１６７９７５号公報Japanese Patent Laid-Open No. 11-167975
　特許文献１に開示のような床面設置型のイオン発生機は、室内の所定の位置に設置された状態で使用されるため、使用者が一定の位置に留まっているような場合には、イオン発生機と使用者との位置関係によっては、イオン発生機から吹き出される風が使用者に対して常に当たる場合がある。このため、使用者が不快に感じる場合がある。 Since the floor-mounted ion generator as disclosed in Patent Document 1 is used in a state where it is installed at a predetermined position in the room, when the user stays at a certain position, Depending on the positional relationship between the ion generator and the user, the wind blown from the ion generator may always hit the user. For this reason, the user may feel uncomfortable.
　しかしながら、単に風向を変更するのみでは、イオンを室内に供給することができず、イオンの供給と不快感の低減とを両立させることが困難であった。 However, simply changing the wind direction cannot supply ions into the room, making it difficult to achieve both ion supply and reduction in discomfort.
　また、吸込口には、使用者の指等が侵入することを防止しつつ、空気を吸い込み可能に設けられた吸込グリルが設置される。このような吸込グリルは、たとえば複数の開口部を有する格子状に形成され、締結部材等によって吸込口に取付けられている。 In addition, a suction grill provided so as to be able to suck in air while preventing a user's finger or the like from entering is installed in the suction port. Such a suction grill is formed in a lattice shape having a plurality of openings, for example, and is attached to the suction port by a fastening member or the like.
　空気中には塵や埃等が含まれるため、使用期間が長くなると、吸込グリルの開口部が塵や埃等によって目詰まりしたり、汚染されたりする場合がある。また、防塵フィルタを設ける場合であっても、吸込グリルのみならず筐体内部も汚染される場合がある。このような場合には、吸込グリルを取り外して、吸込グリル自体や筐体内部を清掃する必要がある。 Since the air contains dust and dust, the suction grill opening may be clogged or contaminated with dust or dust when the service period is extended. Even when a dustproof filter is provided, not only the suction grille but also the inside of the housing may be contaminated. In such a case, it is necessary to remove the suction grill and clean the suction grill itself or the inside of the housing.
　しかしながら、上述のように吸込グリルの開口部には使用者の指を侵入させることができず、吸込グリルの外枠と吸込口の内周面との間にも十分な隙間が設けられていない。このため、何ら手立てがない場合には、吸込グリルの取り外しに手間が掛かってしまう。 However, as described above, the user's finger cannot enter the opening portion of the suction grille, and there is not enough clearance between the outer frame of the suction grille and the inner peripheral surface of the suction port. . For this reason, it takes time to remove the suction grille when there is no means.
　また、より高い位置に風を送出したいとのニーズもあり、吹出口の位置を変更するために、筐体の高さ位置が可変に調整されることが望まれる。しかしながら、筐体のサイズが大きくなる場合には重量が重くなり、作業が困難となる。このため、重い筐体を昇降させるために、使用者が筐体を支持する土台部に足を踏み込んで踏ん張る場合がある。このような場合には、何ら手立てがないと、筐体を昇降させる際に、使用者が筐体と土台部との間に足を挟み込むことが懸念される。 Also, there is a need to send wind to a higher position, and it is desirable that the height position of the housing be variably adjusted in order to change the position of the outlet. However, when the size of the housing is increased, the weight is increased and the operation becomes difficult. For this reason, in order to raise and lower a heavy casing, a user may step on and step on a base portion that supports the casing. In such a case, there is a concern that the user may pinch his / her foot between the housing and the base portion when raising and lowering the housing without any assistance.
　本発明は、上記のような問題に鑑みてなされたものであり、本発明の第１の目的は、局所的に風向を調整することにより、使用者への不快感を軽減しつつ、イオンを十分に供給することができるイオン発生機を提供することにある。 The present invention has been made in view of the above problems, and a first object of the present invention is to adjust the wind direction locally, thereby reducing the discomfort to the user and reducing ions. The object is to provide an ion generator that can be sufficiently supplied.

　イオン発生装置５０は、左右方向に複数並べて配置されている。プラスイオン発生部５１ａおよびマイナスイオン発生部５１ｂとは、送風方向に交差する方向に互いに距離を持って配置されている。 A plurality of ion generators 50 are arranged in the left-right direction. The plus ion generator 51a and the minus ion generator 51b are arranged with a distance from each other in a direction intersecting the blowing direction.
　複数のイオン発生装置５０は、縦整流板２２ａ～２２ｇによって分割されて左右方向に並ぶ列単位の吹出口に対応する空間に対してプラスイオン発生部５１ａおよびマイナスイオン発生部５１ｂが交互に面するように配置される。 In the plurality of ion generators 50, the positive ion generators 51a and the negative ion generators 51b alternately face spaces corresponding to the row-unit outlets divided by the vertical rectifying plates 22a to 22g and arranged in the left-right direction. Are arranged as follows.
　また、イオン発生素子部５１のプラスイオン発生部５１ａの送風下流側には、イオン発生素子部５２のマイナスイオン発生部が配置され、イオン発生素子部５１のマイナスイオン発生部５１ｂの送風下流側には、イオン発生素子部５２のプラスイオン発生部が配置されている。 In addition, a negative ion generation part of the ion generation element part 52 is arranged on the downstream side of the positive ion generation part 51 a of the ion generation element part 51, and on the downstream side of the negative ion generation part 51 b of the ion generation element part 51. The positive ion generation part of the ion generation element part 52 is arrange | positioned.
　このように、列単位の吹出口に対応する空間毎に送風方向にプラスイオン発生部およびマイナスイオン発生部を互いに距離を持って配置することにより、プラスイオンおよびマイナスイオンの発生直後の衝突を抑制しつつ、これらを混在させて機外へ送出することができる。 In this way, positive ions and negative ions can be prevented from colliding immediately after the generation of positive ions and negative ions by arranging the positive ion generator and negative ion generator at a distance from each other in the air blowing direction for each space corresponding to the outlets in units of rows. However, these can be mixed and sent out of the apparatus.
　さらに、縦整流板２２ａ～２２ｇは、上述のように中央に位置する縦整流板２２ｄの正面に対しての角度を０とし、外側に向かうにつれて徐々に大きな角度で湾曲するため、プラスイオンおよびマイナスイオンを含む空気を広角度に吹出すことができる。これにより、プラスイオンおよびマイナスイオンを室内の遠くまで送出することができる。 Further, since the vertical rectifying plates 22a to 22g have an angle with respect to the front surface of the vertical rectifying plate 22d located at the center as described above and bend gradually at larger angles toward the outside, positive ions and negative ions Air containing ions can be blown at a wide angle. Thereby, positive ions and negative ions can be sent far into the room.
　図９から図１５は、外付けルーバー６０の斜視図、正面図、背面図、上面図、底面図、左側面図、右側面図である。図９から図１５を参照して、外付けルーバー６０の形状について説明する。 9 to 15 are a perspective view, a front view, a rear view, a top view, a bottom view, a left side view, and a right side view of the external louver 60. FIG. The shape of the external louver 60 will be described with reference to FIGS.
　図９から図１５に示すように、外付けルーバー６０は、第１風向調整部６０ａ、第２風向調整部６０ｂおよび連結部６７を含む。第１風向調整部６０ａは、縦整流板２２ｃ，２２ｄおよび横整流板２３ａ，２３ｂに囲まれる部分の吹出口に装着される部位であり、第２風向調整部６０ｂは、縦整流板２２ｄ，２２ｅおよび横整流板２３ａ，２３ｂに囲まれる部分の吹出口に装着される部位である。 As shown in FIGS. 9 to 15, the external louver 60 includes a first wind direction adjusting unit 60 a, a second wind direction adjusting unit 60 b, and a connecting unit 67. The 1st wind direction adjustment part 60a is a site | part attached to the blower outlet of the part enclosed by the vertical rectification plates 22c and 22d and the horizontal rectification plates 23a and 23b, and the 2nd wind direction adjustment part 60b is the vertical rectification plates 22d and 22e. And it is a site | part mounted | worn with the blower outlet of the part enclosed by the horizontal rectifying plates 23a and 23b.
　第１風向調整部６０ａは、風向調整板部６１ａ、装着部６２ａおよび開口部６３ａを含む。風向調整板部６１ａは、縦整流板２２ｃ，２２ｄおよび横整流板２３ａ，２３ｂに囲まれる部分の吹出口の上下方向における途中部に設けられる。風向調整板部６１ａは、当該吹出口の出口側から前方へ突出するように設けられている。風向調整板部６１ａは、装着時において左右方向の幅が縦整流板２２ｃから縦整流板２２ｄに至るように構成されている。 1st wind direction adjustment part 60a contains wind direction adjustment board part 61a, mounting part 62a, and opening part 63a. The wind direction adjusting plate portion 61a is provided at an intermediate portion in the vertical direction of the outlet of the portion surrounded by the vertical rectifying plates 22c and 22d and the horizontal rectifying plates 23a and 23b. The wind direction adjusting plate portion 61a is provided so as to protrude forward from the outlet side of the air outlet. The wind direction adjusting plate portion 61a is configured such that, when mounted, the width in the left-right direction extends from the vertical rectifying plate 22c to the vertical rectifying plate 22d.
　風向調整板部６１ａは、後方側から前方側へ向かうにつれて上方に湾曲するように設けられている。風向調整板部６１ａは、下面側が凸となり、上面側が凹となるように湾曲する。このような形状を有することにより、当該吹出口から吹出される空気のうち風向調整板部６１ａよりも上方側に位置する空気を上方に向けて送風することができる。なお、風向調整板部６１ａの形状は、上記のような湾曲形状に限定されず、後方から前方へ向かうにつれて上方へ傾斜する傾斜形状であってもよい。 The wind direction adjusting plate portion 61a is provided so as to curve upward as it goes from the rear side to the front side. The wind direction adjusting plate portion 61a is curved so that the lower surface side is convex and the upper surface side is concave. By having such a shape, it is possible to blow upward air that is located above the airflow direction adjusting plate portion 61a out of the air blown out from the blowout port. The shape of the wind direction adjusting plate portion 61a is not limited to the curved shape as described above, and may be an inclined shape that is inclined upward as it goes from the rear to the front.
　装着部６２ａは、略枠状に設けられている。装着部６２ａは、左側側壁部６４ａ、右側側壁部６５ａ、および底面部６６ａを含む。左側側壁部６４ａは、縦整流板２２ｃに沿うように設けられている。左側側壁部６４ａの先端は、後方に向けて折り返されている。これにより、左側側壁部６４ａの先端側には、縦整流板２２ｃの先端に引っ掛かる係止部６４ａ１が設けられている。 The mounting portion 62a is provided in a substantially frame shape. The mounting portion 62a includes a left side wall portion 64a, a right side wall portion 65a, and a bottom surface portion 66a. The left side wall portion 64a is provided along the vertical rectifying plate 22c. The front end of the left side wall portion 64a is folded back toward the rear. Thereby, the latching | locking part 64a1 hooked on the front-end | tip of the vertical rectifying plate 22c is provided in the front end side of the left side wall part 64a.
　右側側壁部６５ａは、縦整流板２２ｄの前方側の一部に沿うように設けられている。右側側壁部６５ａの前方側から後方側にかけての奥行は、左側側壁部６４ａの前方側から後方側へかけての奥行よりも短くなっている。また、左側側壁部６５ｂの先端は、後方に向けて折り返されている。これにより、右側側壁部６４ｂの先端側には、縦整流板２２ｄの先端に引っ掛かる係止部６５ａ１が設けられている。 The right side wall 65a is provided along a part of the front side of the vertical rectifying plate 22d. The depth from the front side to the rear side of the right side wall portion 65a is shorter than the depth from the front side to the rear side of the left side wall portion 64a. Moreover, the front-end | tip of the left side wall part 65b is turned toward the back. Thereby, the latching | locking part 65a1 hooked on the front-end | tip of the vertical rectifying plate 22d is provided in the front end side of the right side wall part 64b.
　底面部６６ａは、横整流板２３ｂに沿うように設けられている。底面部６６ａには、後方側に切欠き部６６ａ１が設けられている。切欠き部６６ａ１には、装着時に横整流板２３ｂに設けられた突起部（不図示）が嵌り込む。これにより、位置決めを容易に行なうことができる。 The bottom surface portion 66a is provided along the horizontal rectifying plate 23b. The bottom surface portion 66a is provided with a notch portion 66a1 on the rear side. A protrusion (not shown) provided on the horizontal rectifying plate 23b is fitted into the notch 66a1 when the notch 66a1 is attached. Thereby, positioning can be performed easily.
　開口部６３ａは、枠状の装着部６２ａの内周面によって規定される部分である。開口部６３ａは、縦整流板２２ｃ，２２ｄおよび横整流板２３ａ，２３ｂに囲まれる部分の吹出口に連通するように設けられている。 The opening 63a is a portion defined by the inner peripheral surface of the frame-shaped mounting portion 62a. The opening 63a is provided so as to communicate with a blowout port in a portion surrounded by the vertical rectifying plates 22c and 22d and the horizontal rectifying plates 23a and 23b.
　第２風向調整部６０ｂは、風向調整板部６１ｂ、装着部６２ｂおよび開口部６３ｂを含む。風向調整板部６１ｂは、装着時において左右方向の幅が縦整流板２２ｅから縦整流板２２ｄに至るように構成されている。装着部６２ｂは、右側側壁部６４ｂ、左側側壁部６５ｂ、底面部６６ｂを含む。第２風向調整部６０ｂは、ほぼ鏡面対象にした構成である。第２風向調整部６０ｂの各構成部分は、第１風向調整部６０ａとほぼ同様の機能を有する。 The second wind direction adjusting part 60b includes a wind direction adjusting plate part 61b, a mounting part 62b and an opening part 63b. The wind direction adjusting plate portion 61b is configured such that the width in the left-right direction extends from the vertical rectifying plate 22e to the vertical rectifying plate 22d when mounted. The mounting portion 62b includes a right side wall portion 64b, a left side wall portion 65b, and a bottom surface portion 66b. The 2nd wind direction adjustment part 60b is the structure made into mirror surface object substantially. Each component of the second wind direction adjustment unit 60b has substantially the same function as the first wind direction adjustment unit 60a.
　連結部６７は、第１風向調整部６０ａと第２風向調整部６０ｂとを連結する。連結部６７を設けることにより、第１風向調整部６０ａと第２風向調整部６０ｂとを同時にルーバー２１に装着することができる。このため、第１風向調整部６０ａと第２風向調整部６０ｂとを個別にルーバー２１に装着する場合と比較して、装着の手間が省ける。なお、連結部６７は省略してもよい。 The connecting part 67 connects the first wind direction adjusting part 60a and the second wind direction adjusting part 60b. By providing the connection part 67, the 1st wind direction adjustment part 60a and the 2nd wind direction adjustment part 60b can be attached to the louver 21 simultaneously. For this reason, compared with the case where the 1st wind direction adjustment part 60a and the 2nd wind direction adjustment part 60b are separately mounted in the louver 21, the effort of mounting can be saved. The connecting part 67 may be omitted.
　上記の構成のイオン発生機１において、イオン発生装置５０および送風機３０が駆動されると、室内の空気が吸込口１０から筐体２内に取り込まれる。筐体２内に取り込まれた空気は、エアフィルタ１５で塵埃が捕集され、送風経路４０の第１部分４１を通って送風機３０に導かれる。 In the ion generator 1 configured as described above, when the ion generator 50 and the blower 30 are driven, indoor air is taken into the housing 2 from the suction port 10. The air taken into the housing 2 is collected by the air filter 15 and guided to the blower 30 through the first portion 41 of the blower path 40.
　送風機３０は、送風経路４０の第２部分４２に向けて空気（気流）を送風する。送風機３０からの気流は、導風板４５によって第１空気流と第２空気流に分割される。第１空気流は、導風板４５の上方側にある第１経路４６を通って、第１吹出口２６から吹出される。第２空気流は、導風板４５の下方側にある第２経路４７を通って、第２吹出口２７から吹出される。 The blower 30 blows air (airflow) toward the second portion 42 of the blower path 40. The air flow from the blower 30 is divided into a first air flow and a second air flow by the air guide plate 45. The first air flow is blown out from the first air outlet 26 through the first path 46 on the upper side of the air guide plate 45. The second air flow is blown out from the second air outlet 27 through the second path 47 on the lower side of the air guide plate 45.
　この間に、イオン発生装置５０のマイナスイオン発生部およびプラスイオン発生部のそれぞれからマイナスイオンおよびプラスイオンが発生される。イオン発生装置５０は、第１経路４６から離れており、第２経路４７側に位置する。このため、第１経路４６を通過する第１空気流よりも第２経路４７を通過する空気流に多くのイオンが含まれることになる。 During this time, negative ions and positive ions are generated from the negative ion generator and the positive ion generator of the ion generator 50, respectively. The ion generator 50 is separated from the first path 46 and is located on the second path 47 side. For this reason, more ions are included in the air flow passing through the second path 47 than in the first air flow passing through the first path 46.
　また、第１経路４６は、第２経路４７よりも外周側にあるため、外周側に位置する第１空気流の風速は、内周側に位置する第２空気流の風速よりも速くなる。このため、第１吹出口２６から吹出される第１空気流は、エアカーテンとして機能し、イオンの上方への拡散を抑制する。 Further, since the first path 46 is on the outer peripheral side than the second path 47, the wind speed of the first air flow located on the outer peripheral side is faster than the wind speed of the second air flow located on the inner peripheral side. For this reason, the 1st airflow blown from the 1st blower outlet 26 functions as an air curtain, and suppresses the spreading | diffusion of ion upwards.
　ここで、中央領域Ｒ２（図２参照）においては、外付けルーバー６０が設けられている。外付けルーバー６０は、上側吹出口２８から吹出される空気流、すなわち、第１空気流と第２空気流のうち外付けルーバー６０の上方側と通過する空気流とを上方に向けて案内する。風速の速い空気流が上方に案内されるため、中央領域Ｒ２の正面に使用者が一定時間座っているような場合には、風速の速い空気流が使用者に当たることを防止することができる。 Here, an external louver 60 is provided in the central region R2 (see FIG. 2). The external louver 60 guides the air flow blown from the upper air outlet 28, that is, the air flow passing through the upper side of the external louver 60 out of the first air flow and the second air flow upward. . Since the air flow having a high wind speed is guided upward, it is possible to prevent the air flow having a high wind speed from hitting the user when the user is sitting in front of the central region R2 for a certain period of time.
　なお、所定の傾斜具合または湾曲具合を有する外付けルーバー６０によって上方に案内される風速の速い空気流もエアカーテンとして機能する。このため、中央領域Ｒ２の下側吹出口２９から吹出される空気流に含まれるイオンの拡散も程よく抑制することができる。これにより、風速の速い空気流が使用者に当たることを防止しつつ、除菌効果を有するイオンを使用者の周辺に運ぶことができる。 It should be noted that an air flow having a high wind speed guided upward by the external louver 60 having a predetermined inclination or curvature also functions as an air curtain. For this reason, it is possible to moderately suppress the diffusion of ions contained in the air flow blown from the lower outlet 29 of the central region R2. Thereby, the ion which has a disinfection effect can be carried to a user's circumference | surroundings, preventing that an air flow with a high wind speed hits a user.
　続いて、比較例１および比較例２におけるイオン発生機から吹出される空気流および本実施の形態に係るイオン発生機１から吹出される空気流を比較しつつ、本実施の形態１に係るイオン発生機１の効果について説明する。 Subsequently, while comparing the air flow blown from the ion generator in Comparative Example 1 and Comparative Example 2 with the air flow blown from the ion generator 1 according to the present embodiment, the ions according to the first embodiment are compared. The effect of the generator 1 will be described.
　図１６は、比較例１におけるイオン発生機から送風される空気流を示す図である。図１７は、比較例１におけるイオン発生機から送風される空気流の所定の位置における風速分布を示す図である。図１８は、比較例１におけるイオン発生機から送風される空気流に含まれるイオンの濃度分布を示す図である。図１６から図１８を参照して、比較例１におけるイオン発生機から送出される空気流について説明する。 FIG. 16 is a diagram showing an air flow blown from the ion generator in Comparative Example 1. FIG. 17 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator in Comparative Example 1. FIG. 18 is a diagram showing the concentration distribution of ions contained in the air flow blown from the ion generator in Comparative Example 1. With reference to FIGS. 16 to 18, the air flow delivered from the ion generator in Comparative Example 1 will be described.
　なお、図１６から図１８の空気流は、イオン発生機の筐体が最下位位置に位置する状態で吹出されるものである。また、図１６および図１８においては、イオン発生機の中心線Ｃ１（図２参照）と前後方向（Ｙ軸方向）とに平行な平面内における空気流およびこれに含まれるイオン濃度を示している。 In addition, the airflow of FIGS. 16-18 is blown in the state which the housing | casing of an ion generator is located in the lowest position. 16 and 18 show the air flow in a plane parallel to the center line C1 (see FIG. 2) and the front-rear direction (Y-axis direction) of the ion generator, and the ion concentration contained therein. .
　また、使用者が座っている位置をイオン発生機１の中央領域から前方へ１．０ｍ離れた位置とし、使用者が座った際の頭部の位置を床面から１．２ｍとしている。この頭部の位置を位置Ｐ１と規定する。 Also, the position where the user is sitting is a position 1.0 m away from the central area of the ion generator 1, and the position of the head when the user is sitting is 1.2 m from the floor. This head position is defined as a position P1.
　比較例１におけるイオン発生機は、実施の形態１に係るイオン発生機１と比較した場合に、外付けルーバー６０を備えていない点において相違する。その他の構成については、ほぼ同様である。 The ion generator in the comparative example 1 is different in that the external louver 60 is not provided when compared with the ion generator 1 according to the first embodiment. Other configurations are almost the same.
　図１６に示すように、比較例１におけるイオン発生機では、外付けルーバー６０が設けられておらず、風速の速い空気流を上方に案内することができない。この場合における空気流の中心線Ｌ１の仰角θ１は、略２９度となる。ここで、空気流の中心線とは、空気流を正面方向に複数に分割していった場合に最も風速が速くなる部分を結んだ線である。 As shown in FIG. 16, in the ion generator in Comparative Example 1, the external louver 60 is not provided, and an air flow having a high wind speed cannot be guided upward. In this case, the elevation angle θ1 of the center line L1 of the air flow is approximately 29 degrees. Here, the center line of the air flow is a line connecting portions where the wind speed is highest when the air flow is divided into a plurality of parts in the front direction.
　この場合においては、イオン発生機の中央領域Ｒ２（図２参照）の吹出口から吹出される空気流は、上方側が位置Ｐ１を通過するように吹出される。このため、当該吹出口から吹出される空気流は、使用者の頭部近傍に直接当たることになる。 In this case, the airflow blown out from the blowout port of the central region R2 (see FIG. 2) of the ion generator is blown out so that the upper side passes through the position P1. For this reason, the airflow which blows off from the said blower outlet hits a user's head vicinity directly.
　図１７は、イオン発生機の中央から前方へ１．０ｍの位置において、前方方向に直交し、左右方向に平行な平面内の所定の領域における風速分布を示している。当該所定の領域とは、たとえば、上記平面内のうちイオン発生機の中心線に対応する部分を中心として、左右方向に８０ｃｍの幅を有し、上下方向に１４０ｃｍの高さを有する矩形形状の領域である。当該領域の上端は、床面から１４０ｃｍの位置に位置する。 FIG. 17 shows a wind speed distribution in a predetermined region in a plane orthogonal to the front direction and parallel to the left-right direction at a position 1.0 m forward from the center of the ion generator. The predetermined region is, for example, a rectangular shape having a width of 80 cm in the left-right direction and a height of 140 cm in the up-down direction around the portion corresponding to the center line of the ion generator in the plane. It is an area. The upper end of the region is located 140 cm from the floor surface.
　図１７に示すように、風速が１．０ｍ／ｓより大きく１．５ｍ／ｓ以下の範囲であり、最も速くなる空気流Ｆ１は、床面から７０ｃｍ以上１１５ｃｍ以下の範囲内に位置する。風速が０．５ｍ／ｓより大きく１．０ｍ／ｓ以下の範囲であり、次いで速くなる空気流Ｆ２は、床面から６０ｃｍ以上１１５ｃｍ以下の範囲内において最も速い空気流Ｆ２を取り囲むように存在する。風速が０．５ｍ／ｓ以下であり、風速の遅い空気流Ｆ３は、空気流Ｆ２を取り囲むように存在する。 As shown in FIG. 17, the wind speed is in the range of greater than 1.0 m / s and less than or equal to 1.5 m / s, and the fastest air flow F1 is located within the range of 70 cm to 115 cm from the floor surface. The air flow F2 in which the wind speed is greater than 0.5 m / s and 1.0 m / s or less and then increases is present so as to surround the fastest air flow F2 within the range of 60 cm to 115 cm from the floor surface. . An air flow F3 having a wind speed of 0.5 m / s or less and a slow wind speed exists so as to surround the air flow F2.
　このように、比較例１においては、使用者の頭部近傍に最も風速が速い空気流が当たるため、使用者は、空気流を不快に感じてしまう場合がある。 Thus, in Comparative Example 1, since the airflow with the fastest wind speed hits the vicinity of the user's head, the user may feel the airflow uncomfortable.
　一方で、図１８に示すように、比較例１におけるイオン発生機は、相当程度のイオンを含む空気を室内の上方に向けて送ることができる。室内の上方に送られたイオンは、時間とともに床面に向けて下降する。このため、室内にイオンを十分に供給することができる。 On the other hand, as shown in FIG. 18, the ion generator in Comparative Example 1 can send air containing a considerable amount of ions upward in the room. The ions sent upward in the room descend toward the floor with time. For this reason, ions can be sufficiently supplied into the room.
　なお、イオン濃度は、吹出方向に沿って吹出口から離れるにつれて（領域Ａ１から領域Ａ５に向かうにつれて）イオン濃度が順に小さくなる。最もイオン濃度が高く領域Ａ１は、位置Ｐ１よりもやや下方に位置するものの、除菌等の効果を発揮させるために十分な量のイオンを使用者に向けて送出することもできる。 Note that the ion concentration decreases in order as the ion concentration moves away from the outlet along the blowing direction (from the region A1 toward the region A5). Although the region A1 having the highest ion concentration is located slightly below the position P1, it is possible to send a sufficient amount of ions toward the user in order to exert effects such as sterilization.
　図１９は、比較例２におけるイオン発生機から送風される空気流を示す図である。図２０は、比較例２におけるイオン発生機から送風される空気流の所定の位置における風速分布を示す図である。図２１は、比較例２におけるイオン発生機から送風される空気流に含まれるイオンの濃度分布を示す図である。図１９から図２１を参照して、比較例２におけるイオン発生機から送出される空気流について説明する。 FIG. 19 is a diagram showing an air flow blown from the ion generator in Comparative Example 2. FIG. 20 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator in Comparative Example 2. FIG. 21 is a diagram showing the concentration distribution of ions contained in the air flow blown from the ion generator in Comparative Example 2. With reference to FIG. 19 to FIG. 21, the air flow delivered from the ion generator in Comparative Example 2 will be described.
　なお、図１９は、図１６に対応する図であり、図２０は、図１７に対応する図であり、図２１は、図１８に対応する図である。図１９から図２１に示す空気流は、比較例１に係るイオン発生機の筐体を最下位位置から３０ｃｍ上方へ移動させた状態で吹出されるものである。 19 is a diagram corresponding to FIG. 16, FIG. 20 is a diagram corresponding to FIG. 17, and FIG. 21 is a diagram corresponding to FIG. The airflow shown in FIGS. 19 to 21 is blown out in a state where the casing of the ion generator according to Comparative Example 1 is moved upward by 30 cm from the lowest position.
　図１９に示すように、比較例２におけるイオン発生機から吹出される空気流の中心線Ｌ２の仰角θ２は、略２７度であり、比較例１の仰角θ１とほぼ同様である。このため、図１９から図２１に示すように、比較例２における空気流の状態は、比較例１における空気流を上方へ３０ｃｍ移動させた状態とほぼ同等となる。 As shown in FIG. 19, the elevation angle θ2 of the center line L2 of the air flow blown from the ion generator in Comparative Example 2 is approximately 27 degrees, which is substantially the same as the elevation angle θ1 of Comparative Example 1. For this reason, as shown in FIGS. 19 to 21, the state of the air flow in the comparative example 2 is substantially equivalent to the state in which the air flow in the comparative example 1 is moved upward by 30 cm.
　具体的には、図１９に示すように、中心線Ｌ２が位置Ｐ１の若干上方を通過し、図２０に示すように、最も風速の速い空気流Ｆ１の中心が位置Ｐ１の若干上方に位置する。このため、使用者の頭部に最も風速の速い空気流Ｆ１が直接当たることになり、使用者は、空気流を不快に感じてしまう場合がある。 Specifically, as shown in FIG. 19, the center line L2 passes slightly above the position P1, and as shown in FIG. 20, the center of the air flow F1 with the fastest wind speed is located slightly above the position P1. . For this reason, the air flow F1 with the fastest wind speed directly hits the user's head, and the user may feel the air flow uncomfortable.
　一方で、図２１に示すように、比較例２におけるイオン発生機も相当程度のイオンを含む空気を室内の上方に向けて送ることができる。イオン発生機から所定の距離前方に位置し、当該イオン発生機の中心線と左右方向に平行な平面内を格子状に分割した際に形成される複数の格子点のそれぞれで、イオン濃度を測定した場合におけるイオン濃度の平均値は、比較例１と比較してプラスイオンの濃度およびマイナスイオンの濃度ともに１３％程度の低減に留まっている。 On the other hand, as shown in FIG. 21, the ion generator in Comparative Example 2 can also send air containing a considerable amount of ions toward the upper part of the room. Ion concentration is measured at each of a plurality of lattice points that are located in front of an ion generator at a predetermined distance and divided into a lattice shape in a plane parallel to the center line of the ion generator and the horizontal direction. In this case, the average value of the ion concentration is only about 13% lower than that of Comparative Example 1 in both the positive ion concentration and the negative ion concentration.
　このため、比較例２においても、比較例１同様に室内にイオンを十分に供給できるといえる。また、最もイオン濃度が高くなる領域Ａ１は、位置Ｐ１を含むように吹出方向に広がる。このため、除菌等の効果を発揮させるために十分な量のイオンを使用者に向けて送ることもできる。 For this reason, in Comparative Example 2, it can be said that ions can be sufficiently supplied into the room as in Comparative Example 1. Further, the region A1 where the ion concentration is highest spreads in the blowing direction so as to include the position P1. For this reason, it is also possible to send a sufficient amount of ions to the user in order to exert effects such as sterilization.
　図２２は、本実施の形態に係るイオン発生機から送風される空気流を示す図である。図２３は、本実施の形態に係るイオン発生機から送風される空気流の所定の位置における風速分布を示す図である。図２４は、本実施の形態に係るイオン発生機から送風される空気流に含まれるイオンの濃度分布を示す図である。図２２から図２４を参照して、本実施の形態に係るイオン発生機１から吹出される空気流について説明する。 FIG. 22 is a diagram showing an air flow blown from the ion generator according to the present embodiment. FIG. 23 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator according to the present embodiment. FIG. 24 is a diagram showing a concentration distribution of ions contained in an air flow blown from the ion generator according to the present embodiment. With reference to FIG. 22 to FIG. 24, the air flow blown out from the ion generator 1 according to the present embodiment will be described.
　なお、図２２は、図１６に対応する図であり、図２３は、図１７に対応する図であり、図２４は、図１８に対応する図である。図２２から図２４に示す空気流は、イオン発生機１の筐体２が最下位位置に位置する状態から３０ｃｍ上方に移動させた状態で吹出されるものである。 22 is a diagram corresponding to FIG. 16, FIG. 23 is a diagram corresponding to FIG. 17, and FIG. 24 is a diagram corresponding to FIG. The air flow shown in FIGS. 22 to 24 is blown out in a state where the casing 2 of the ion generator 1 is moved upward by 30 cm from the state where the casing 2 is located at the lowest position.
　図２２に示すように、外付けルーバー６０を設けることにより、中央領域Ｒ２において吹出口から吹出される空気流が上方へ向かうようになる。この場合においては、空気流の中心線Ｌ３の仰角θ３は、比較例１，２における仰角よりも大きく、略３８度となる。 As shown in FIG. 22, by providing the external louver 60, the airflow blown out from the outlet in the central region R2 is directed upward. In this case, the elevation angle θ3 of the center line L3 of the air flow is larger than the elevation angle in Comparative Examples 1 and 2, and is approximately 38 degrees.
　イオン発生機１の中央領域Ｒ２に位置する吹出口から吹出される空気流は、全体的に位置Ｐ１の上方を通過している。このため、中央領域Ｒ２に位置する吹出口から吹出される空気流は、使用者にほぼ当たらない。 The airflow blown out from the outlet located in the central region R2 of the ion generator 1 passes above the position P1 as a whole. For this reason, the airflow blown from the blower outlet located in center area | region R2 does not hit a user substantially.
　図２３に示すように、次いで風速の速い空気流Ｆ２は、床面から１２０ｃｍの位置よりも上方に位置し、最も速い空気流Ｆ１を取り囲むように存在する。また、風速が遅い空気流Ｆ３が、空気流Ｆ２を取り囲むように存在する。図２３には図示されていないが、最も風速の速い空気流Ｆ１における中心線Ｃ１に対応する位置の下端は、横座標の値が０となる部分における空気流Ｆ１の下端は、１５０ｃｍよりも若干高い位置に位置する。 As shown in FIG. 23, the air flow F2 with the next highest wind speed is located above the position 120 cm from the floor surface and surrounds the fastest air flow F1. Moreover, the air flow F3 with a slow wind speed exists so that the air flow F2 may be surrounded. Although not shown in FIG. 23, the lower end of the position corresponding to the center line C1 in the air flow F1 with the highest wind speed is slightly lower than 150 cm at the lower end of the air flow F1 in the portion where the value of the abscissa is 0. Located at a high position.
　本実施の形態においては、最も風速が速い空気流Ｆ１は、使用者に当たらずに、風速が遅い、空気流Ｆ３が使用者に当たる。空気流Ｆ３は、使用者に不快感を与えない風である。このため、本実施の形態においては、使用者の不快感を大幅に低減させることができる。 In the present embodiment, the air flow F1 with the fastest wind speed does not hit the user, but the air flow F3 with the slow wind speed hits the user. The air flow F3 is a wind that does not cause discomfort to the user. For this reason, in this Embodiment, a user's discomfort can be reduced significantly.
　図２４に示すように、本実施の形態に係るイオン発生装置も相当程度のイオンを含む空気を室内の上方に向けて送ることができる。室内の上方に送られたイオンは、時間とともに床面に向けて下降する。 As shown in FIG. 24, the ion generating apparatus according to the present embodiment can also send air containing a considerable amount of ions upward in the room. The ions sent upward in the room descend toward the floor with time.
　外付けルーバー６０を設けることにより、イオンの拡散具合も比較例１と比較すると若干異なってくる。イオン発生機から所定の距離前方に位置し、当該イオン発生機の中心線と左右方向に平行な平面内を格子状に分割した際に形成される複数の格子点のそれぞれで、イオン濃度を測定した場合におけるイオン濃度の平均値は、比較例１と比較してプラスイオンの濃度およびマイナスイオンの濃度ともに１０％程度の低減に留まっている。このため、実施の形態１に係るイオン発生機１においても室内にイオンを十分に供給できると言える。 By providing the external louver 60, the diffusion of ions is slightly different from that of Comparative Example 1. Ion concentration is measured at each of a plurality of lattice points that are located in front of an ion generator at a predetermined distance and divided into a lattice shape in a plane parallel to the center line of the ion generator and the horizontal direction. In this case, the average value of the ion concentration is only about 10% lower than that of Comparative Example 1 in both the positive ion concentration and the negative ion concentration. For this reason, it can be said that the ion generator 1 according to Embodiment 1 can sufficiently supply ions into the room.
　また、最もイオン濃度が高くなる領域Ａ１は、位置Ｐ１を含むように吹出方向に広がっている。このため、除菌等の効果を発揮させるために十分な量のイオンを使用者に向けて送ることもできる。 Further, the region A1 where the ion concentration is highest is widened in the blowing direction so as to include the position P1. For this reason, it is also possible to send a sufficient amount of ions to the user in order to exert effects such as sterilization.
　なお、筐体２の位置を最下位位置とした場合には、図２３の状態から空気流Ｆ１、空気流Ｆ２、空気流Ｆ３の位置がそれぞれ略３０ｃｍ低くなった位置に位置することになる。この場合には、横座標の値が０となる部分における空気流Ｆ１の下端は、１２０ｃｍよりも若干上に位置する。空気流Ｆ１の下端部は、当該横座標の値が０となる部分から左右方向に広がりながら下方に傾斜する。このため、使用者の頭部には、最も風速の速い空気流Ｆ１は、当たらなくなる。 In addition, when the position of the housing | casing 2 is made into the lowest position, it will be located in the position where the position of the air flow F1, the air flow F2, and the air flow F3 became about 30 cm low from the state of FIG. In this case, the lower end of the air flow F1 in the portion where the value of the abscissa is 0 is located slightly above 120 cm. The lower end of the air flow F1 is inclined downward while spreading in the left-right direction from the portion where the value of the abscissa is zero. For this reason, the air flow F1 with the fastest wind speed does not hit the user's head.
　この場合には、使用者の頭部には、空気流Ｆ２が当たることになるが、空気流Ｆ２は、空気流Ｆ１よりも風速が低いため、使用者に与える不快感を軽減することができる。なお、この場合においても室内の上方に向けて相当程度イオンを含む空気流を吹出すことができるため、室内にイオンを十分に供給できる。 In this case, the air flow F2 hits the user's head. However, since the air flow F2 has a lower wind speed than the air flow F1, discomfort given to the user can be reduced. . In this case as well, since an air flow containing a considerable amount of ions can be blown upward in the room, ions can be sufficiently supplied into the room.
　以上のように、本実施の形態に係るイオン発生機１は、比較例１，２と比較して、使用者に除菌等に十分なイオンを送りつつ、使用者に与える違和感や不快感を軽減することができる。 As described above, the ion generator 1 according to the present embodiment has a sense of discomfort and discomfort given to the user while sending sufficient ions for sterilization and the like to the user as compared with Comparative Examples 1 and 2. Can be reduced.
　図２５は、本実施の形態に係るイオン発生機の筐体を昇降させる場合における筐体と足との関係を示す図である。図２５を参照して、イオン発生機１の筐体２を昇降させる場合における足と筐体との関係を示す。 FIG. 25 is a diagram showing the relationship between the case and the legs when the case of the ion generator according to the present embodiment is raised and lowered. Referring to FIG. 25, the relationship between the foot and the case when the case 2 of the ion generator 1 is raised and lowered is shown.
　図２５に示すように、イオン発生機１は相当程度の重量を有するため、イオン発生機１の筐体２を一人で昇降させる際に、踏ん張りが効くように土台部５を足で踏み込む場合がある。 As shown in FIG. 25, since the ion generator 1 has a considerable weight, when the casing 2 of the ion generator 1 is lifted and lowered by one person, the base part 5 may be stepped on with a foot so that the tension is effective. is there.
　筐体２を上下方向に移動させたい場合には、まず、上述の固定部材６の締め付けを緩め固定部材６を支柱部４の挿通穴から抜き出す。続いて、左側面部２ａおよび右側面部２ｂ内に設けられたガイド突起部（不図示）を支柱部４の溝部４ａに沿ってスライド移動させる。 When it is desired to move the housing 2 in the vertical direction, first, the fixing member 6 is loosened and the fixing member 6 is removed from the insertion hole of the support column 4. Subsequently, guide protrusions (not shown) provided in the left side surface portion 2 a and the right side surface portion 2 b are slid along the groove portion 4 a of the support column portion 4.
　次に、左側面部２ａおよび右側面部２ｂに設けられた貫通孔７を、所定の位置に設けられた溝部４ａの挿通孔に合わせる。続いて、固定部材６を挿通穴に挿通しこれを締め付けて筐体２を所定の高さ位置に固定する。 Next, the through holes 7 provided in the left side surface portion 2a and the right side surface portion 2b are aligned with the insertion holes of the groove portions 4a provided at predetermined positions. Subsequently, the fixing member 6 is inserted into the insertion hole and tightened to fix the housing 2 at a predetermined height position.
　なお、上記のガイド突起部は、貫通孔７の下方に設けられている。このため、溝部４ａの下端にガイド突起部が到達した場合に筐体２が最下位位置に位置することになる。このように筐体２の移動範囲が規制されることにより、本実施の形態に係るイオン発生機１は、筐体２が最下位位置に位置する場合であっても筐体２の底面部２ｃと足とが接触しないように構成されている。 Note that the above-described guide protrusion is provided below the through hole 7. For this reason, when the guide projection reaches the lower end of the groove 4a, the housing 2 is positioned at the lowest position. By restricting the movement range of the housing 2 in this way, the ion generator 1 according to the present embodiment is capable of the bottom surface portion 2c of the housing 2 even when the housing 2 is located at the lowest position. And the foot are configured not to contact each other.
　このため、足が筐体２の底面部２ｃと土台部５の上面とによって挟み込まれることを防止でき、昇降作業の安全性を確保することができる。 For this reason, it is possible to prevent the foot from being sandwiched between the bottom surface portion 2c of the housing 2 and the top surface of the base portion 5, and to ensure the safety of the lifting operation.
　なお、本実施の形態においては、筐体２の上下方向の移動範囲を規制する規制手段がガイド突起部と溝部とによって構成される場合を例示して説明したが、これに限定されず、ストッパー等の部材によって規制手段を構成してもよい。 In the present embodiment, the case where the restricting means for restricting the vertical movement range of the casing 2 is configured by the guide protrusion and the groove has been described as an example. However, the present invention is not limited to this, and the stopper The restricting means may be configured by a member such as.
　（実施の形態２）
　図２６は、本実施の形態に係るイオン発生機の底面図である。図２６を参照して、本実施の形態に係るイオン発生機１Ａについて説明する。 (Embodiment 2)
FIG. 26 is a bottom view of the ion generator according to the present embodiment. With reference to FIG. 26, the ion generator 1A according to the present embodiment will be described.
　図２６に示すように、本実施の形態に係るイオン発生機１Ａは、実施の形態１と比較した場合に、吸込グリル１１Ａの構成が相違する。その他の構成については、ほぼ同様である。 As shown in FIG. 26, the ion generator 1A according to the present embodiment is different from the first embodiment in the configuration of the suction grill 11A. Other configurations are almost the same.
　吸込グリル１１Ａは、吸込口１０に設置され、複数の開口部１２，１３を有する。筐体２内においては、送風機カバー３１の一部が吸込口１０の後方側に左右方向に亘って面するように配置されている。 The suction grill 11 </ b> A is installed at the suction port 10 and has a plurality of openings 12 and 13. In the housing 2, a part of the blower cover 31 is arranged so as to face the rear side of the suction port 10 in the left-right direction.
　吸込グリル１１Ａのうち送風機カバー３１に面さない部分は、指先の侵入を防止するように形成された複数の開口部１２によって構成されている。すなわち、開口部１２の大きさが、指先よりも小さくなっている。 The portion of the suction grill 11A that does not face the blower cover 31 is composed of a plurality of openings 12 that are formed so as to prevent the fingertip from entering. That is, the size of the opening 12 is smaller than the fingertip.
　一方、吸込グリル１１Ａのうち送風機カバー３１に面する部分は、指先が侵入可能となるように形成された開口部１３を含むように構成されている。開口部１３は、たとえば、左右方向の両端側のそれぞれに設けられていることが好ましい。なお、吸込グリル１１Ａのうち送風機カバー３１に面する部分のうち、開口部１３以外の部分は、指先の侵入を防止するように形成された開口部１２によって構成されている。 On the other hand, the portion of the suction grill 11A that faces the blower cover 31 is configured to include an opening 13 that is formed so that a fingertip can enter. For example, the opening 13 is preferably provided on each of both end sides in the left-right direction. Of the portion of the suction grill 11 </ b> A that faces the blower cover 31, the portion other than the opening 13 is configured by the opening 12 that is formed to prevent the fingertip from entering.
　吸込グリル１１Ａを取り外す際には、まず、吸込グリル１１Ａを筐体２に締結する締結部材を外す。次に、開口部１３に指先を挿入して指先に吸込グリル１１Ａの一部を引掛ける。続いて、指先に吸込グリル１１Ａを引掛けてこれを引っ張ることにより、吸込グリル１１Ａを吸込口１０から容易に取り外すことができる。このように吸込グリル１１Ａの取り外しに手間がかからないため、筐体２内の部品を容易に交換したり、清掃したりすることができる。この結果、部品交換、清掃等の作業性を大幅に向上させることができる。 When removing the suction grill 11A, first, a fastening member for fastening the suction grill 11A to the housing 2 is removed. Next, a fingertip is inserted into the opening 13 and a part of the suction grill 11A is hooked on the fingertip. Subsequently, the suction grill 11A can be easily removed from the suction port 10 by hooking the suction grill 11A on the fingertip and pulling it. Thus, since it takes no effort to remove the suction grill 11A, the components in the housing 2 can be easily replaced or cleaned. As a result, workability such as component replacement and cleaning can be greatly improved.
　また、筐体２内において開口部１３に対向する部分には送風機カバー３１が設けられているため、指先が送風機３０の羽根に巻き込まれることを防止することができる。これにより安全性を確保することができる。 Moreover, since the blower cover 31 is provided in the portion facing the opening 13 in the housing 2, it is possible to prevent the fingertip from being caught in the blades of the blower 30. Thereby, safety can be ensured.
　このように本実施の形態に係るイオン発生機１Ａは、実施の形態１に係るイオン発生機１とほぼ同様の効果が得られるのに加えて、安全性を確保しつつ、吸込口に設置される吸込グリルの取り外しを容易に行なうことができ、清掃等の作業性を向上させることができるイオン発生機を提供することができる。 Thus, the ion generator 1A according to the present embodiment is installed at the suction port while ensuring safety in addition to obtaining substantially the same effect as the ion generator 1 according to the first embodiment. Therefore, it is possible to provide an ion generator that can easily remove the suction grill and can improve workability such as cleaning.
　なお、本実施の形態においては、イオン発生機１Ａの構成が吸込グリル１１Ａを除いて実施の形態１に係るイオン発生機１とほぼ同様である場合を例示して説明したが、これに限定されない。吹出口および吸込口が設けられた筐体と、筐体内に設けられ、吹出口と吸込口とを接続する送風経路と、送風経路内にイオンを発生させるイオン発生装置と、送風経路内に配置され、吸込口から吸込んだ空気を吹出口に送風する送風機と、吸込口の一部に面するように配置された送風機カバーと、吸込口に設置され、複数の開口部を有する吸込グリルとを備えたイオン発生装置であれば、本実施の形態に係る吸込グリル１１Ａの構成を適用することができる。 In addition, in this Embodiment, although the structure of ion generator 1A illustrated and demonstrated the case where it was substantially the same as that of the ion generator 1 which concerns on Embodiment 1 except the suction grill 11A, it is not limited to this. . A housing provided with a blower outlet and a suction port, a blower path provided in the housing and connecting the blower outlet and the suction port, an ion generator for generating ions in the blower path, and an arrangement in the blower path A blower that blows air sucked from the suction port to the blower outlet, a blower cover that is arranged so as to face a part of the suction port, and a suction grill that is installed in the suction port and has a plurality of openings. If it is an ion generator provided, the configuration of the suction grill 11A according to the present embodiment can be applied.
　（実施の形態３）
　図２７は、本実施の形態に係るイオン発生機の右側面図である。図２７を参照して、本実施の形態に係るイオン発生機１Ｂについて説明する。 (Embodiment 3)
FIG. 27 is a right side view of the ion generator according to the present embodiment. With reference to FIG. 27, the ion generator 1B which concerns on this Embodiment is demonstrated.
　図２７に示すように、本実施の形態に係るイオン発生機１Ｂは、実施の形態１に係るイオン発生機１と比較した場合に、土台部５の上面に踏込防止手段９０が設けられている点において相違する。その他の構成については、ほぼ同様である。 As shown in FIG. 27, the ion generator 1B according to the present embodiment is provided with a step-in prevention means 90 on the upper surface of the base portion 5 when compared with the ion generator 1 according to the first embodiment. The point is different. Other configurations are almost the same.
　踏込防止手段９０は、たとえば、人が踏み込んだ場合に違和感や不快感を与える突起部９１が設けられていることが好ましい。なお、踏込防止手段９０自体が突起状であってもよい。踏込防止手段９０は、射出成型等により土台部５と一体に構成されていてもよいし、別体で構成されていてもよい。 It is preferable that the stepping prevention means 90 is provided with a protrusion 91 that gives a sense of incongruity or discomfort when a person steps on, for example. Note that the stepping-in preventing means 90 itself may be a protrusion. The step-in prevention means 90 may be configured integrally with the base portion 5 by injection molding or the like, or may be configured separately.
　この場合には、使用者がイオン発生機１Ｂの筐体２を一人で昇降させる際に、土台部５を踏み込むと、突起部９１（突起状の部分）に足裏が接触する。このため、使用者は、足裏に違和感を覚え、土台部５への踏み込みを回避して足を土台部５側から床面に移動させる。これにより、筐体２を最下位位置に下降させた場合であっても、筐体２と土台部５とによって足が挟まれることを防止することができる。この結果、本実施の形態に係るイオン発生機１Ｂは、昇降作業の安全性を確保することができる。 In this case, when the user steps up and down the casing 2 of the ion generator 1B alone, when the base unit 5 is stepped on, the sole contacts the protrusion 91 (protruded portion). For this reason, the user feels uncomfortable on the sole of the foot, avoids stepping into the base portion 5, and moves the foot from the base portion 5 side to the floor surface. Thereby, even if it is a case where the housing | casing 2 is lowered | hung to the lowest position, it can prevent that a leg | foot is pinched by the housing | casing 2 and the base part 5. FIG. As a result, the ion generator 1B according to the present embodiment can ensure the safety of the lifting operation.
　なお、本実施の形態においては、イオン発生機１Ｂの構成が踏込防止手段９０の構成を除いて実施の形態１に係るイオン発生機１とほぼ同様である場合を例示して説明したが、これに限定されない。吹出口および吸込口が設けられた筐体と、筐体内に収容され、吹出口と吸込口とを接続する送風経路と、送風経路内にイオンを発生させるイオン発生装置と、送風経路内に配置され、吸込口から吸い込んだ空気を吹出口に送風する送風機と筐体を上下方向に移動可能に支持する脚部と、を備え、脚部が床面に設置される土台部を含む構成のイオン発生機であれば、本実施の形態に係る踏込防止手段の構成を適用することができる。 In the present embodiment, the case where the configuration of the ion generator 1B is substantially the same as that of the ion generator 1 according to the first embodiment except for the configuration of the step-in prevention means 90 has been described as an example. It is not limited to. A housing provided with an air outlet and a suction port, an air passage that is accommodated in the housing and connects the air outlet and the air inlet, an ion generator that generates ions in the air passage, and an air passage An air blower that blows air sucked from the air inlet to the air outlet and a leg portion that supports the casing so as to be movable in the vertical direction, and includes a base portion on which the leg portion is installed on the floor surface. If it is a generator, the structure of the step-in prevention means according to the present embodiment can be applied.
　以上のように、本実施の形態に係るイオン発生機１Ｂは、実施の形態１に係るイオン発生機１とほぼ同様の効果が得られるのに加えて、昇降作業時の安全性を確保することができる。 As described above, the ion generator 1B according to the present embodiment ensures the safety during the lifting operation in addition to obtaining substantially the same effect as the ion generator 1 according to the first embodiment. Can do.
　（実施の形態４）
　図２８から図３４は、本実施の形態に係る外付けルーバーの斜視図、正面図、背面図、上面図、底面図、左側面図、右側面図である。図２８から図３４を参照して、外付けルーバー６０Ａの形状について説明する。 (Embodiment 4)
28 to 34 are a perspective view, a front view, a rear view, a top view, a bottom view, a left side view, and a right side view of the external louver according to the present embodiment. The shape of the external louver 60A will be described with reference to FIGS.
　図２８から図３４に示すように、本実施の形態に係る外付けルーバー６０Ａは、実施の形態１に係る外付けルーバー６０と比較した場合に、連結部６７を備えていない点および第１風向調整部６０ａおよび第２風向調整部６０ｂに含まれる風向調整板部６１ｃおよび６１ｄの形状が相違する。 As shown in FIGS. 28 to 34, the external louver 60A according to the present embodiment is not provided with the connecting portion 67 and the first wind direction when compared with the external louver 60 according to the first embodiment. The shapes of the wind direction adjusting plate portions 61c and 61d included in the adjusting portion 60a and the second wind direction adjusting portion 60b are different.
　風向調整板部６１ｃは、装着時において左右方向の幅が縦整流板２２ｂから縦整流板２２ｄに至るように構成されている。同様に、風向調整板部６１ｄは、装着時において左右方向の幅が縦整流板２２ｆから縦整流板２２ｄに至るように構成されている。 The wind direction adjusting plate portion 61c is configured so that the width in the left-right direction extends from the vertical rectifying plate 22b to the vertical rectifying plate 22d when mounted. Similarly, the wind direction adjusting plate portion 61d is configured such that the width in the left-right direction extends from the vertical rectifying plate 22f to the vertical rectifying plate 22d when mounted.
　このような構成にあっては、中央領域Ｒ２を左右方向に拡張することができる。これにより、本実施の形態に係る外付けルーバー６０Ａを具備するイオン発生機は、実施の形態１に係るイオン発生機１よりも使用者に違和感や不快感を与えない範囲を拡大することができる。 In such a configuration, the central region R2 can be expanded in the left-right direction. Thereby, the ion generator which comprises external louver 60A concerning this embodiment can expand the range which does not give a sense of incongruity and discomfort to a user rather than ion generator 1 concerning Embodiment 1. .
　以上、本発明の実施の形態について説明したが、今回開示された実施の形態はすべての点で例示であって制限的なものではない。本発明の範囲は請求の範囲によって示され、請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 As mentioned above, although embodiment of this invention was described, embodiment disclosed this time is an illustration and restrictive at no points.
