Description

本発明は室内空間の空気浄化を行う空気清浄装置に関する。 The present invention relates to an air purifier for purifying air in an indoor space.

空気清浄装置の能力は、設置空間に漂う汚染物質の浄化性能とその浄化効率により評価がなされている。浄化性能については、空気清浄装置に搭載するフィルタの性能に依存するものであるが、浄化効率は、空気清浄装置の送風能力と空間空気の循環作用に浄化性能とを合わせた効果に依存するといわれている。従来の空気清浄装置の吸引口は、装置の使用部材の中で最も大きな面積を占めるフィルタ通気面の大きさにほぼ一致する形状とし、空気清浄装置のほぼ1平面に配されている。一方、排気口は送風ファンを収納する送風手段の送風口付近に配され、吸引方向に対して垂直方向へと排気するようになっている。この方法によると、吸引風量に対して吸引口面積が大きく、吸い込み風速が小さいので、タバコの煙など広い範囲から効率良く吸引できないことや、排気風速が非常に大きいために、空気清浄装置付近の汚染空気を空間へ拡散させてしまうなどの課題があった。それらの課題に対して、特開２００２−１８６６６２にあるように、空気浄化装置本体の吸引口を前記空気清浄装置本体の外壁のほぼ全面に渡って設けて、汚染空気を装置本体の外壁のほぼ全面から吸引させ、空気清浄装置の設置空間の隅部分に存在する汚染空気がその近傍に留まることを防ぎ、空間内の除去率を均一化させ、汚染空気が存在する空間全体の汚染物質の吸引を速やかに行い、空間全体としての除去効果を増大させる工夫等がなされている。
特開２００２−１８６６６２号公報 The ability of the air purifier is evaluated based on the purification performance of pollutants drifting in the installation space and the purification efficiency. The purification performance depends on the performance of the filter installed in the air purifier, but the purification efficiency is said to depend on the effect of the air purifier combined with the air blowing capacity and the circulation function of the spatial air. ing. The suction port of the conventional air cleaning device has a shape that substantially matches the size of the filter ventilation surface that occupies the largest area among the members in use of the device, and is arranged on almost one plane of the air cleaning device. On the other hand, the exhaust port is disposed in the vicinity of the air blowing port of the air blowing means that houses the air blowing fan, and exhausts in a direction perpendicular to the suction direction. According to this method, the suction port area is large with respect to the suction air volume, and the suction air speed is low, so that it cannot be efficiently suctioned from a wide range such as cigarette smoke, and the exhaust air speed is very large. There were problems such as diffusing contaminated air into the space. In order to solve these problems, as disclosed in JP-A-2002-186661, the suction port of the air purification device main body is provided over almost the entire outer wall of the air purification device main body, so that the contaminated air can be supplied to almost the outer wall of the device main body. Suction from the entire surface prevents contaminated air from staying in the corner of the installation space of the air purifier, makes the removal rate in the space uniform, and sucks contaminants in the entire space where contaminated air exists In order to increase the removal effect of the entire space, etc. have been made.
JP 2002-186661 A

しかしながら、先の発明によると装置近傍の臭気ガスなどの除去率を均一化し、その除去効果を高めることは期待できるが、床面付近に配される排気口は床面に堆積した塵埃粒子や花粉、床面に多く見られるダニ等のアレルゲン物質を空間に巻き上げ拡散させてしまう問題があった。この排気口は小さな開口面積であるため、排気風の風速が大きいので、その影響は更に大きくなる。また、室内で使用する場合には排気風が周りの人に不快感を与えることがあり、装置の設置場所を制限させてしまうという問題があった。 However, according to the previous invention, it can be expected that the removal rate of odorous gas and the like in the vicinity of the apparatus is made uniform and the removal effect is enhanced, but the exhaust port arranged near the floor surface has dust particles and pollen accumulated on the floor surface. There is a problem that allergen substances such as mites that are often found on the floor surface are wound up and diffused in the space. Since the exhaust port has a small opening area, the wind speed of the exhaust air is high, and the influence is further increased. In addition, when used indoors, the exhaust air may cause discomfort to the people around it, which causes a problem of restricting the installation location of the apparatus.

本発明はこのような問題点に鑑みてなされたものであり、タバコの煙などを広範囲から効率よく装置内に吸引するとともに、床面に堆積した塵埃粒子や花粉、床面に多く見られるダニ等のアレルゲン物質を空気中に巻き上げることなく空間の浄化効率を高めるとともに、メンテナンス性を高めた空気清浄装置を提供することを目的とする。
The present invention has been made in view of such problems, and sucks tobacco smoke and the like from a wide range efficiently into the apparatus, and dust particles and pollen accumulated on the floor surface, and mites often found on the floor surface. It is an object of the present invention to provide an air cleaning device that improves the purification efficiency of the space without raising allergen substances such as the like in the air, and also improves the maintainability.

The suction port can be fitted to the periphery of the suction port so as to be airtight, and is pressed between the filter and the suction port periphery of the blower means so as to keep airtight, and the shape of the outer periphery of the adapter is the suction tube. It is the shape which contacts the inner wall of this, or the suction inlet periphery of the said ventilation means.

請求項１記載の発明によると、排気口から出る排気風が床面を直接掃気しないので、床面に堆積した塵埃粒子や花粉、床面に多く見られるダニ等のアレルゲン物質を空間に拡散させずに排気をすることができる。 According to the first aspect of the present invention, since the exhaust air coming out from the exhaust port does not directly scavenge the floor surface, allergen substances such as dust particles and pollen accumulated on the floor surface and ticks often found on the floor surface are diffused into the space. Without exhausting.

請求項２に記載の発明によると、空気清浄装置内に吸引された吸引風が、フィルタ上部を通過する際に、上に凸状となっているフィルタ上部により乱流を抑制して、フィルタ上部から受ける空気抵抗を小さくでき、流路内の吸引抵抗を小さくすることができる。また、乱流の発生を抑えることで柱状フィルタ上部の気流の流れを安定させ、フィルタに流入する空気の偏流を小さくし、フィルタへの吸気流の流入分布を均等にすることができ、フィルタを効率良く使用することができる。 According to the invention described in claim 2, when the suction air sucked into the air purifier passes through the upper part of the filter, the turbulent flow is suppressed by the upper part of the filter that is convex upward, and the upper part of the filter The air resistance received from the air can be reduced, and the suction resistance in the flow path can be reduced. In addition, by suppressing the occurrence of turbulence, the flow of air above the columnar filter can be stabilized, the uneven flow of air flowing into the filter can be reduced, and the inflow distribution of the intake air flow into the filter can be made uniform.

The resistance can be reduced, and the characteristics of the blower fan can be enhanced and used.

請求項４記載の発明によると、装置内にフィルタを装着と交換をする際に、連結アダプタを介してフィルタと送風手段の連結時の位置決めを簡単に行うことができるので、その作業性を大幅に改善することができる。また、アダプタはフィルタおよび送風手段と気密を保てるので、フィルタと送風手段の連結不備によるリークを防止することもでき、フィルタと吸気管の内壁間に形成される吸気路の距離を適正に保つこともできる。さらに、アダプタの一部がフィルタと間隙を設けて配される吸気管の内壁と、あるいは送風手段の吸込み口周縁と一致する形状となっているが密着はしていないので、フィルタを引き抜くとアダプタも一緒に引き抜かれ、フィルタ交換の際にフィルタ表面に付着した埃やゴミ等がフィルタと隔壁の間に落下したとしても、フィルタとともにアダプタにより装置外へと持ち出すことができるので、装置のメンテナンス性を高めることができる。 According to the fourth aspect of the present invention, when the filter is mounted and replaced in the apparatus, the filter and the air blowing means can be easily positioned through the connection adapter, so that the workability is greatly increased. Can be improved. In addition, since the adapter can be kept airtight with the filter and the air blowing means, it is possible to prevent leakage due to improper connection between the filter and the air blowing means, and to keep the distance of the intake passage formed between the filter and the inner wall of the intake pipe properly. You can also. Furthermore, a part of the adapter is shaped to coincide with the inner wall of the intake pipe arranged with a gap between the filter or the peripheral edge of the suction port of the blower means, but it is not in close contact. Even if dust or dirt attached to the filter surface falls between the filter and the partition wall when the filter is replaced, it can be taken out of the device by the adapter together with the filter. Can be increased.

以下、本発明の実施の形態について図を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１（ａ）は、本発明の空気清浄装置の構造を示す横方向断面図面であり、図１（ｂ）は上方より見た断面図である。図１（ａ）に示す装置の上部には、空間空気の導入口である吸引口３があり、フィルタ１２と一定の距離を空けて配される吸気管１０の内壁とで形成される空間は、吸気路１１として装置内に吸引された吸引風６の流路となり、吸気管１０の外壁と装置の側面部４との間に形成される空間は、送風口７より装置外へと排気風８を導く排気路９となる。吸気管１０は、送風手段１５上に形成される吸い込み口１４と送風口７との間に、フィルタ１２と一定の間隙を設けて配され、送風手段１５に嵌合され装着される。吸引風６を浄化するフィルタ１２は、上部が通気性の無い中空の円筒状となっており、下部は吸い込み口１４と一致する形状の開口部１３となっている。そして、開口部１３と吸い込み口１４とを密着して嵌合し送風手段１５に装着されている。排気風８を装置外に排気する排気口５は、空気清浄装置２の側面部全周に渡って開口しており、大きな開口面積となっている。空気清浄装置２の送風手段は、送風ファンである多翼ファン１６とモータ１７とからなり装置の下部に設置されている。 FIG. 1A is a transverse sectional view showing the structure of the air cleaning device of the present invention, and FIG. 1B is a sectional view seen from above. In the upper part of the apparatus shown in FIG. 1 (a), there is a suction port 3 which is an inlet for space air, and the space formed by the filter 12 and the inner wall of the intake pipe 10 arranged with a certain distance is formed. As a suction passage 11, a flow path of the suction air 6 sucked into the apparatus is formed, and a space formed between the outer wall of the intake pipe 10 and the side surface portion 4 of the apparatus is exhausted from the air outlet 7 to the outside of the apparatus. 8 is an exhaust passage 9 that guides 8. The intake pipe 10 is disposed between the suction port 14 formed on the blower unit 15 and the blower port 7 with a certain gap from the filter 12, and is fitted and attached to the blower unit 15. The filter 12 for purifying the suction air 6 has a hollow cylindrical shape with no air permeability at the top, and an opening 13 having a shape that matches the suction port 14 at the bottom. Then, the opening 13 and the suction port 14 are fitted in close contact with each other and attached to the blowing means 15. The exhaust port 5 for exhausting the exhaust air 8 to the outside of the device is opened over the entire circumference of the side surface of the air cleaning device 2 and has a large opening area. The blowing means of the air cleaning device 2 includes a multi-blade fan 16 that is a blowing fan and a motor 17 and is installed at the lower part of the device.

本実施例によれば、吸引風６は空気清浄装置２下部に配してある送風手段１５内にモータ１７と共に収納された多翼ファン１６により吸引され、吸気管１０とフィルタ１２から形成される吸気路１１に侵入しその後、吸気路１１から円筒状のフィルタ１２の中空部へと吸引され濾過される。フィルタ１２は上部が閉鎖された円筒状の中空となっており、その全側面が浮遊塵埃等を捕集する集塵用濾材と活性炭等の脱臭剤や除菌抗菌性を持つ不織布部材等いずれも通気性のある部材を積層し構成されている。本実施例では、フィルタ１２を中空の円筒形状としているが、中空で柱状の形状であれば多角形や楕円形であってもよい。 According to the present embodiment, the suction air 6 is sucked by the multi-blade fan 16 housed together with the motor 17 in the air blowing means 15 arranged at the lower part of the air purifier 2, and is formed from the intake pipe 10 and the filter 12. After entering the intake passage 11, the suction passage 11 is then sucked into the hollow portion of the cylindrical filter 12 and filtered. The filter 12 has a hollow cylindrical shape with the upper part closed, and the entire side of the filter 12 is a filter medium for collecting dust and the like, a deodorant such as activated carbon, and a non-woven member having antibacterial and antibacterial properties. It is constructed by laminating breathable members. In this embodiment, the filter 12 has a hollow cylindrical shape, but may be polygonal or elliptical as long as it is hollow and columnar.

フィルタ１２により濾過され清浄空気となった吸引風６は、フィルタ１２の開口部１３から送風手段１５の吸い込み口１４へと侵入し、多翼ファン１６を経て送風手段１５の送風口７へと導かれる。多翼ファン１６は、高い送風能力を持つシロッコファンやターボファンであり、装置の接地面と平行して配してあり、３．０ｍ３／ｍｉｎ程度の処理能力を持った装置としている。 The suction air 6 that has been filtered by the filter 12 to become clean air enters the suction port 14 of the blower means 15 from the opening 13 of the filter 12, and is guided to the blower port 7 of the blower means 15 through the multiblade fan 16. It is burned. The multi-blade fan 16 is a sirocco fan or a turbo fan having a high blowing capacity, and is arranged in parallel with the ground contact surface of the apparatus, and has a processing capacity of about 3.0 m <3> / min.

図１（ｂ）に示すように送風手段１５の送風口７は２口あり、吸い込み口１４と同じように、送風手段１５の上面に上方向を向き開口しているが、送風手段１５の上面に装着されている吸気管１０により、吸い込み口１４と送風口７はそれぞれ分離されている。送風口７は吸気管１０の外壁と、装置の側面部４との間に形成される排気路９に開口している。送風口７は製品形状や大きさ、装置の処理風量に合わせて、１口でも複数でもよい。送風口７より排気される排気風８は、吸気管１０と側面部４との間に形成され上部が閉鎖されている排気路９の下部から上部へと導かれ、空気清浄装置２の側面部全周に渡って開口し、複数のスリットにより形成された排気口５より装置外へと排気される。本実施例においては、空気清浄装置２の外郭形状を円筒形状としているが、柱状の楕円形や多角形であってもよい。 As shown in FIG. 1B, there are two air outlets 7 of the air blowing means 15, and like the air inlet 14, it opens upward on the upper surface of the air blowing means 15. The suction port 14 and the air blowing port 7 are separated from each other by the intake pipe 10 attached to the air intake pipe 10. The blower opening 7 opens into an exhaust passage 9 formed between the outer wall of the intake pipe 10 and the side surface portion 4 of the apparatus. The blower port 7 may be one or more, depending on the product shape and size, and the processing air volume of the apparatus. The exhaust air 8 exhausted from the blower port 7 is guided from the lower part of the exhaust passage 9 formed between the intake pipe 10 and the side part 4 and closed at the upper part to the upper part of the air cleaner 2. It opens over the entire circumference and is exhausted out of the apparatus through an exhaust port 5 formed by a plurality of slits. In this embodiment, the outer shape of the air cleaning device 2 is a cylindrical shape, but it may be a columnar ellipse or a polygon.

ここで、本実施例における空気清浄装置２の簡単なスペックについて説明すると、製品の大きさは、側面部４がφ１６０ｍｍの円形で、高さが５００ｍｍであり、処理風量は３．０ｍ^３／ｍｉｎである。この時の吸引口３の風速は、吸引口３の開口面積がφ１２４ｍｍなのでその通風断面積は０．０１２１ｍ^２であり、空気清浄装置２の処理風量を３．０ｍ^３／ｍｉｎとした場合、４．１ｍ／ｓと非常に大きくすることができ、空間空気中に漂い拡散してゆくタバコの煙等を広範囲から効率よく吸引することができる。一方、排気口５の開口面積は、開口している高さを３７０ｍｍ程度とすると０．１８６０ｍ^２となる。排気口５の開口形状がスリット形状であり、開口率が７０％なので、その排気風８の風速は０．３８ｍ／ｓとなり極めて小さくすることができるので、排気風により床面に堆積した塵埃粒子や花粉、床面に多く見られるダニ等のアレルゲン物質を空間に拡散させることもなく、また周囲の人や物などに影響を与えることも無い。排気風８については、空気清浄装置２の処理風量や、目的に合わせて排気路９の上部の閉鎖する位置や、排気口５の開口しているスリットの大きさや位置、配置を変えて最適化することが望ましい。 Here, the simple specifications of the air cleaning device 2 in the present embodiment will be described. The size of the product is a circular shape in which the side surface 4 is φ160 mm, the height is 500 mm, and the processing air volume is 3.0 m ³ / min. It is. At this time, since the opening area of the suction port 3 is φ124 mm, the ventilation cross-sectional area is 0.0121 m ² , and the air speed of the suction port 3 is 4 when the processing air volume of the air cleaning device 2 is 3.0 m ³ / min. .M / s can be made very large, and smoke and the like that drift in the air can be efficiently sucked from a wide range. On the other hand, the opening area of the exhaust port 5 is 0.1860 m ² when the opening height is about 370 mm. Since the opening shape of the exhaust port 5 is a slit shape and the opening rate is 70%, the wind speed of the exhaust air 8 is 0.38 m / s, which can be extremely small. Therefore, dust particles accumulated on the floor surface by the exhaust air. It does not diffuse allergens such as ticks, pollen and ticks that are often found on the floor, and does not affect the surrounding people or objects. The exhaust air 8 is optimized by changing the processing air volume of the air cleaning device 2, the position where the upper portion of the exhaust passage 9 is closed, and the size, position, and arrangement of the slit opening the exhaust port 5 according to the purpose. It is desirable to do.

図２は第２実施例の構成を示す図である。図２（ａ）は空気清浄装置２に使用するフィルタ１２を円柱形状とし、その上部を通気性のない円錐状部１９としたものである。また、図２（ｂ）はフィルタ１２を多角形状とし、その上部を同様に通気性の無い錐形状としたものである。このような形状にすることで、空気清浄装置２に吸引された空間空気１が、フィルタ１２の上部を通過する際に、錐形状部１９により乱流を抑制して、空気抵抗を小さくでき、流路内の通風抵抗を小さくすることができる。また、乱流の発生を抑えることで柱状フィルタ上部の気流の流れを安定させ、フィルタに流入する空気の偏流を小さくし、フィルタへの吸引風６の流入分布を均等にすることができるので、フィルタを効率良く使用することができる。また、フィルタ１２の形状を柱状で中空の楕円形や別形状とした場合でも、上部の錐形状部１９をフィルタ１２の形状に合わせた錐形状とすることで、同様の効果を得ることができる。 FIG. 2 is a diagram showing the configuration of the second embodiment. FIG. 2A shows a filter 12 used in the air cleaning device 2 having a cylindrical shape, and an upper portion of the filter 12 having a conical portion 19 having no air permeability. FIG. 2B shows the filter 12 having a polygonal shape, and the upper portion of the filter 12 having a conical shape without air permeability. By making such a shape, when the spatial air 1 sucked into the air cleaning device 2 passes through the upper part of the filter 12, it is possible to suppress the turbulent flow by the cone-shaped portion 19 and reduce the air resistance, Ventilation resistance in the flow path can be reduced. In addition, by suppressing the occurrence of turbulent flow, the flow of air at the top of the columnar filter can be stabilized, the drift of air flowing into the filter can be reduced, and the inflow distribution of the suction air 6 to the filter can be made uniform. The filter can be used efficiently. In addition, even when the shape of the filter 12 is a columnar hollow ellipse or another shape, the same effect can be obtained by making the upper cone-shaped portion 19 a cone shape matching the shape of the filter 12. .

図３（ａ）は第３実施例を示す斜視図である。送風手段１５上に形成される送風口７を、送風手段１５上面から排気方向に延伸して形成される送風路２１を経て設けている。図３（ｂ）に示すように、送風口７は排気路９の下部に位置しており、送風路２１を経て送風口７より排出された排気風８は、吸気管１０の外壁と側面部４とで形成される排気路９を通り、排気口５より装置外へと排出される。送風路２１の高さは３０ｍｍ以上が望ましく、本実施例では５０ｍｍとしている。この高さは、風量や送風口７の開口面積とその形状により最適化をすることが望ましい。 FIG. 3A is a perspective view showing a third embodiment. The blower port 7 formed on the blower unit 15 is provided through a blower passage 21 formed by extending from the upper surface of the blower unit 15 in the exhaust direction. As shown in FIG. 3 (b), the air blowing port 7 is located in the lower part of the exhaust passage 9, and the exhaust air 8 discharged from the air blowing port 7 through the air blowing passage 21 is connected to the outer wall and the side surface portion of the intake pipe 10. 4 passes through the exhaust passage 9 formed by the exhaust port 4 and is discharged out of the apparatus through the exhaust port 5. The height of the air passage 21 is desirably 30 mm or more, and is 50 mm in this embodiment. It is desirable to optimize this height according to the air volume, the opening area of the air blowing port 7 and its shape.

本実施例によれば、送風手段１５から排気口５の開口したスリットの最下部付近に位置した送風口７まで形成された送風路２１により、送風ファンからの排気風を整流し排気抵抗を小さくすることができ、送風ファンの特性を高めて使用することができる。 According to the present embodiment, the exhaust air flow from the blower fan is rectified by the blower passage 21 formed from the blower means 15 to the blower opening 7 located in the vicinity of the lowermost part of the slit of the exhaust outlet 5 to reduce the exhaust resistance. It is possible to enhance the characteristics of the blower fan.

本実施例によると、フィルタ１２と送風手段１５との装着時において、フィルタ１２とアダプタ２３を別途装着した後に、アダプタ２３を吸気管接触部２４と吸気管１０の内壁を沿わせて送風手段１５に装着させることができるので、フィルタ１２の交換作業性を大幅に改善することができる。また、フィルタ１２と送風手段１５の連結不備によるリークを防止でき、またフィルタ１２と吸気管１０の内壁間に形成される吸気路１１の距離を適正に保つこともできる。さらに、アダプタの一部がフィルタ１２と間隙を設けて配される吸気管の内壁と、あるいは送風手段の吸込み口周縁と一致する形状となっているが密着はしていないので、フィルタを引き抜くとアダプタも一緒に引き抜かれ、フィルタ１２の交換時にフィルタ１２の表面に付着した埃やゴミ等がフィルタ１２と吸気管１０の内壁の間に落下したとしても、フィルタ１２とともにアダプタ２３により装置外へと持ち出すことができるので、装置のメンテナンス性を高めることができる。本実施例では、フィルタ１２を中空の円筒形状としているが、柱状で中空の楕円形や多角形とした場合はアダプタ２３のフィルタ装着部２２の形状をそれらと同一形状にし、吸気管１０が楕円や多角形状である場合にはアダプタ２７の吸気管接触部２４は吸気管１０の内壁形状と一致する形状とすることで同様の効果を得ることができる。また、本実施例ではアダプタ２３がフィルタ１２の内壁と嵌合しているが、フィルタ１２の外壁あるいはその両方と嵌合してもよい。さらに送風手段１５との押圧も送風手段１５の吸込み口１４の端面でも上面でよく、吸気管１０内でのフィルタの固定方法は任意でよい。 According to this embodiment, when the filter 12 and the air blowing means 15 are attached, after the filter 12 and the adapter 23 are separately attached, the adapter 23 is placed along the intake pipe contact portion 24 and the inner wall of the air intake pipe 10. Therefore, the workability for replacing the filter 12 can be greatly improved. In addition, it is possible to prevent leakage due to improper connection between the filter 12 and the air blowing means 15, and to keep the distance of the intake passage 11 formed between the filter 12 and the inner wall of the intake pipe 10 appropriate. Furthermore, a part of the adapter has a shape that coincides with the inner wall of the intake pipe arranged with a gap from the filter 12 or the peripheral edge of the suction port of the blower means, but is not in close contact, so when the filter is pulled out Even if the adapter is pulled out together, and dust or dirt adhering to the surface of the filter 12 is dropped between the filter 12 and the inner wall of the intake pipe 10 when the filter 12 is replaced, the adapter 23 together with the filter 12 is taken out of the apparatus. Since it can be taken out, the maintainability of the apparatus can be improved. In this embodiment, the filter 12 has a hollow cylindrical shape. However, in the case of a columnar hollow ellipse or polygon, the shape of the filter mounting portion 22 of the adapter 23 is the same as that, and the intake pipe 10 is elliptical. In the case of a polygonal shape, the same effect can be obtained by making the intake pipe contact portion 24 of the adapter 27 coincide with the inner wall shape of the intake pipe 10. In the present embodiment, the adapter 23 is fitted to the inner wall of the filter 12, but may be fitted to the outer wall of the filter 12 or both. Further, the pressure with the blowing means 15 may be the upper surface of the suction port 14 of the blowing means 15, and the filter fixing method in the intake pipe 10 may be arbitrary.
