【０００１】
【発明の属する技術分野】
本発明は、芳香器に関する。
【０００２】
【従来の技術】
特開平10-85313号公報に記載の、ハウジング内に香料収納部を設け、モータにより駆動されるファンを送風室に設け、香料収納部から出る香気をこのファンにより送風室に吸引して吹出す芳香器がある。
【０００３】
然しながら、芳香器において、ハウジングの外形寸法に対し香料収納部の容積を可及的に大きくし、結果として、ハウジング内の香料収納部回りに形成される送風室への空気取入れ通路の流路面積が狭小になると、ファンが作動したときに十分な空気を取入れできず、芳香吹出し風量を多くできない。
【０００４】
【発明が解決しようとする課題】
本発明の課題は、芳香器において、香料収納部の容積を可及的に大きくしながら、芳香吹出し風量を多くとることにある。
【０００５】
【課題を解決するための手段】
本発明は、モータにより駆動されるファンを、モータケースの天面と送風ケースの上仕切板と側仕切板とで仕切られる送風室に設け、この送風室の中心に配置したファンにより香料収納部から出る香気を上仕切板の中央かつファンの中心上方に配置した吸引口から送風室に吸引して吹出す芳香器であって、送風ケースにおいてファンが設けられる送風室を仕切る前記上仕切板の吸引口の直ぐ上流側に該吸引口を介して該送風室に連通する空気溜め部を設け、香料収納部がその下方の出口を介して該空気溜め部に連通すると共に、香料収納部回りに設けた狭小、かつ該香料収納部を貫通しない空気取入れ通路を上記空気溜め部に連通してなるようにしたものである。
【０００６】
【発明の実施の形態】
芳香器１０は、図１〜図３に示す如く、モータケース１１と、送風ケース１２と、芳香タンク１３を積層した 3層構造体である。
【０００７】
モータケース１１は、電池２３、モータ２４を収納し、モータ２４の出力軸２４Ａはモータケース１１の天面に設けた軸孔２５を貫通し、その貫通端にファン２６を圧入している。
【０００８】
送風ケース１２は、モータケース１１に係合した状態で、モータケース１１の天面と上仕切板３３と側仕切板３４とで囲まれる送風室３５を形成し、この送風室３５の中心にファン２６を配置し、上仕切板３３の中央に設けた吸引口３６をファン２６の中心上方に配置し、送風室３５の外周側で側仕切板３４の略Ｃ字の切れ目に対応する送風ケース１２の側面に設けた吹出し口３７を配置している。
【０００９】
芳香タンク１３は、香料収納カセット４１と、カバー４２とから構成される。香料収納カセット４１は、有底半球状をなし、香料１（芳香剤）を収納する香料収納部を構成している。香料収納カセット４１は、球体頂面に１以上の入口４３Ａを開口し、底面中央に出口４３Ｂを開口している。香料収納カセット４１は、送風ケース１２の上仕切板３３の上面の支持突部３８上に載置され、筒部４４を上仕切板３３の中央の吸引口３６に配置している。
【００１０】
カバー４２は送風ケース１２に着脱される。カバー４２は、球体頂面に空気取入れ口４７を備え、送風ケース１２に係着された状態で、香料収納カセット４１の外面との間に空気取入れ通路４８（空気取入れ通路４８は、香料収納カセット４１の底面と送風ケース１２の上仕切板３３の上面との間を吸引口３６にまで延在する）を形成する。
【００１１】
従って、芳香器１０は、モータ２４がファン２６を駆動すると、カバー４２の空気取入れ口４７からカバー４２と香料収納カセット４１との間を通る空気取入れ通路４８を経て空気が吸引口３６から送風室３５に吸引されるとともに、カバー４２の空気取入れ口４７から香料収納カセット４１の入口４３Ａ、出口４３Ｂを通る香気取入れ通路４９により香料収納カセット４１内の香気が吸引口３６から送風室３５に吸引される。これにより、空気と香気が送風室３５でミックスされて芳香を生成し、送風ケース１２の側面の吹出し口３７から室内に吹出すものとなる。
【００１２】
然るに、芳香器１０にあっては、送風ケース１２において、モータ２４により駆動されるファン２６が設けられる送風室３５の吸引口３６の直ぐ上流側に陥凹状の空気溜め部５１を設け、香料収納カセット４１とカバー４２の間に設けた狭小な空気取入れ通路４８（本実施形態では香料収納カセット４１の外形をカバー４２の内周に可及的に近づけ、香料収納カセット４１の香料収納容積を可及的に拡大してあるため、空気取入れ通路４８は狭小になっている）を上記空気溜め部５１に連通している。
【００１３】
即ち、芳香器１０にあっては、香料収納カセット４１の容積を大きくとると、香料収納カセット４１回りに形成される送風室３５への空気取入れ通路４８の流路面積が狭小にならざるを得ないが、ファン２６が作動したときに、直ぐ上流の空気溜め部５１からスムースに空気が吸引され、結果として、十分な空気を取入れることができ、芳香吹出し風量を多くすることができる。
【００１４】
図４は、芳香器１０を用いた実験結果であり、ファン２６の回転時に送風室３５の吹出し口３７から吹出される芳香吹出し風速Ｖ（m/s ）と、上述の空気溜め部５１の容積Ｑ（cm3 ）との関係を示す。空気溜め部５１の容積が大なるほど香気吹出し風速は大きくなる。
【００１５】
【発明の効果】
本発明によれば、芳香器において、香料収納部の容積を可及的に大きくしながら、芳香吹出し風量を多くとることができる。

The blow-out opening 37 provided on the side surface is arranged.
[0009]
The fragrance tank 13 includes a fragrance storage cassette 41 and a cover 42. The perfume storage cassette 41 has a bottomed hemispherical shape and constitutes a perfume storage unit that stores perfume 1 (fragrance). The perfume storage cassette 41 has one or more inlets 43A opened on the top surface of the sphere, and an outlet 43B opened in the center of the bottom surface. The fragrance storage cassette 41 is placed on the support protrusion 38 on the upper surface of the upper partition plate 33 of the blower case 12, and the cylindrical portion 44 is disposed in the suction port 36 at the center of the upper partition plate 33.
[0010]
The cover 42 is attached to and detached from the blower case 12. The cover 42 is provided with an air intake port 47 on the top surface of the sphere, and is engaged with the blower case 12 so that the air intake passage 48 (the air intake passage 48 is a fragrance storage cassette) between the outer surface of the fragrance storage cassette 41. 41 and the upper surface of the upper partition plate 33 of the blower case 12 extend to the suction port 36).
[0011]
Therefore, when the motor 24 drives the fan 26, the fragrance device 10 has air flowing from the suction port 36 through the air intake passage 48 passing between the cover 42 and the fragrance storage cassette 41 from the air intake port 47 of the cover 42. 35, and the fragrance in the fragrance storage cassette 41 is sucked from the suction port 36 into the blower chamber 35 through the fragrance intake passage 49 passing through the inlet 43 </ b> A and the outlet 43 </ b> B of the fragrance storage cassette 41 from the air intake port 47 of the cover 42.
