　An air purifier that purifies air taken in from outside by a fan and blows the air from an outlet (17), wherein the outlet (17) is horizontally long, and the vertical width (H1) at the center in the widthwise direction is wider than the vertical width (H2) at the edges. A plurality of air-directing plates (17a) are arranged side-by-side in a horizontal direction in the outlet (17) at intervals, the plate surfaces of said air-direction plates being in a vertical position that extends in the vertical direction and along the direction in which the air is blown. The closer the position of the plate surface to an end of the outlet in the horizontal direction, the more the plate surface faces towards the outflow side and opens towards the outside in the horizontal direction. The air purifier has an air passage which has one end in the air flow direction connected to the inflow side of the outlet (17), and the cross-section of which perpendicular to the air flow direction is horizontally long. The abovementioned fan is a crossflow fan arranged in the air passage so that the rotary shaft is oriented along the lengthwise direction of the horizontally long cross section of the air passage.

Description

空気清浄機Air cleaner
　本発明は、浄化空気及びイオン等を室内に供給する空気清浄機に関する。 The present invention relates to an air cleaner that supplies purified air, ions, and the like into a room.
　従来、空気清浄機では、送風ファンによって外部から吸い込まれた空気が通風路を流れ、通風路に設けた浄化フィルタによって空気中に含まれる有害物質等が除去されて浄化されると共に、イオン発生器で発生したイオンを浄化空気と共に横長の矩形状の吹出口から吹き出す構成が公知である（特許文献１参照）。 Conventionally, in an air purifier, air sucked from the outside by a blower fan flows through a ventilation path, and harmful substances contained in the air are removed and purified by a purification filter provided in the ventilation path, and an ion generator The structure which blows out the ion which generate | occur | produced in (2) from the oblong rectangular blower outlet with purified air is known (refer patent document 1).
特開２００９－１４２３５６号公報JP 2009-142356 A
　従来の空気清浄機では、吹出口から吹き出すイオンを含む空気の風速が速い場合、使用者に直接風が当たると、肌寒く感じるという問題が発生する（特に冬の時期で問題となり易い）。この場合に、吹出し風量を減少させて風速を下げることにより不快感を解消させることは可能である。しかし、吹出し風量が減少すると、室内に供給される浄化空気の供給量が少なくなり、イオン濃度も低下するという問題が生じる。 In conventional air purifiers, when the wind speed of the air containing ions blown from the outlet is high, there is a problem that the user feels chilly when the wind hits the user directly (especially in winter season). In this case, it is possible to eliminate discomfort by reducing the blown air volume and lowering the wind speed. However, when the amount of blown air decreases, there is a problem that the amount of purified air supplied to the room decreases and the ion concentration also decreases.
　本発明は、上述したような事情に鑑みてなされたものであり、吹出口からの吹き出し風による不快感を防止すると共に、室内等に対する浄化空気等の供給効率を維持することができる空気清浄機を提供することを目的とする。 The present invention has been made in view of the above-described circumstances, and can prevent an unpleasant feeling caused by a blowout air from an air outlet and can maintain the supply efficiency of purified air or the like to a room or the like. The purpose is to provide.
　本発明に係る空気清浄機は、送風機により外部から吸い込んだ空気を浄化し、吹出口から吹き出す空気清浄機において、前記吹出口は横長であり、横方向の中央部での上下幅が端部での上下幅よりも広いことを特徴とする。 The air purifier according to the present invention purifies air sucked from the outside by a blower and blows out from the blower outlet, wherein the blower outlet is horizontally long, and the vertical width at the central portion in the lateral direction is at the end. It is characterized by being wider than the vertical width of the.
　本発明によれば、送風機により外部から吸い込まれた空気が浄化され、浄化された空気は横方向の中央部での上下幅が端部での上下幅よりも広い横長の吹出口から外部へ吹き出される。ここで、内部側から吹出口に流入する浄化空気の風量が横方向で略均一の分布である場合、横長の吹出口の横方向での単位横幅当たりの面積は中央部で端部よりも広く、風速は風量を面積で割って算出されるので、中央部での風速は端部での風速よりも遅くなる。 According to the present invention, the air sucked in from the outside is purified by the blower, and the purified air is blown out from the horizontally long air outlet whose vertical width at the central portion in the horizontal direction is wider than the vertical width at the end portion. Is done. Here, when the air volume of the purified air flowing into the air outlet from the inside has a substantially uniform distribution in the lateral direction, the area per unit lateral width in the lateral direction of the horizontally elongated air outlet is wider at the center than at the end. Since the wind speed is calculated by dividing the air volume by the area, the wind speed at the center is slower than the wind speed at the end.
　本発明に係る空気清浄機は、通風方向における一端が前記吹出口の流入側に繋がり、通風方向と直交する断面が横長である通風路を有し、前記送風機は、回転軸の方向が前記通風路の横長の断面の長手方向に沿うように前記通風路に配置されたクロスフローファンであることを特徴とする。
　本発明によれば、通風方向における一端が横長の吹出口の流入側に繋がる通風路に回転軸の方向が該通風路の横長の断面の長手方向に沿うように配置されたクロスフローファンが回転作動し、外部から吸い込まれた空気が横長の断面の通風路を流れ、横長の吹出口から外部に吹き出される。その結果、浄化された空気が安定した層流状態で吹き出すので、室内等に向けて効率よく浄化空気を供給することができる。 The air cleaner according to the present invention has a ventilation path in which one end in the ventilation direction is connected to the inflow side of the air outlet, and a cross section perpendicular to the ventilation direction is horizontally long. It is a cross flow fan arranged in the ventilation path so as to be along the longitudinal direction of the horizontally long cross section of the road.
According to the present invention, the cross-flow fan arranged in such a way that one end in the ventilation direction is connected to the inflow side of the horizontally long outlet and the direction of the rotation axis is along the longitudinal direction of the horizontally long cross section of the ventilation path is rotated. Actuated, the air sucked in from the outside flows through the ventilation passage having a horizontally long cross section, and is blown out from the horizontally long air outlet. As a result, since the purified air is blown out in a stable laminar flow state, the purified air can be efficiently supplied toward the room or the like.
　本発明に係る空気清浄機は、前記吹出口は、板面が上下方向及び吹出し方向に沿った縦姿勢をなし、横方向の端部側に位置するほど板面が流出側に向かって横外方向に開いた複数の風向板を横方向に間隔を置いて並置させていることを特徴とする。
　本発明によれば、板面が上下方向及び吹出し方向に沿った縦姿勢をなし、横方向に間隔を置いて並置された複数の風向板が端部側に位置するほど板面が流出側に向かって横外方向に開いているので、横方向に隣り合う風向板の流出側での間隔が流入側に対して大きくなり、その結果、吹出口からの吹き出し風の風速が低下し、吹き出し風が当たることによる不快感を更に低下させることができる。 In the air purifier according to the present invention, the air outlet has a vertical posture in which the plate surface is along the vertical direction and the blow-out direction, and the plate surface is laterally outward toward the outflow side as it is positioned at the lateral end side. A plurality of wind direction plates opened in the direction are juxtaposed at intervals in the horizontal direction.
According to the present invention, the plate surface has a vertical posture along the vertical direction and the blowing direction, and the plate surface is closer to the outflow side as a plurality of wind direction plates juxtaposed at intervals in the horizontal direction are positioned on the end side. Since the distance between the wind direction plates adjacent in the lateral direction on the outflow side is larger than that on the inflow side, the wind speed of the blowout air from the blowout port decreases, and the blowout airflow is reduced. The discomfort caused by hitting can be further reduced.

The blower outlet 17 is provided with a plurality of vertical wind direction plates 17a and horizontal wind direction plates 17b juxtaposed at intervals in the horizontal direction. As the wind direction plate 17a in the vertical posture is positioned at both ends in the lateral direction, the plate surface is opened in the laterally outward direction toward the outflow side (FIG. 4). As a result, the flow of air blown forward from the outlet 17 can be expanded in the lateral direction. The horizontal wind direction plate 17b is for making the flow of the air blown forward to a substantially horizontal state. Note that the vertical wind direction plate 17a and the horizontal wind direction plate 17b are formed of integrally formed members.

The suction port 18 has an upper portion located on the front side of the cross flow fan 21 and a lower portion located below the cross flow fan 21 and inclined forward. The suction port 18 is on the upper side with respect to the suction port 2 a provided in the rear panel 2. Specifically, the upper end portion of the suction port 18 is higher than the suction port 2a at the uppermost position, and the lower end portion of the suction port 18 is lower than the suction port 2a at the uppermost position but is at the height of the housing 1. It is in a position above approximately half and is higher than the suction port 2a at the lowest position.
　吸込口１８には防塵フィルタ１９が縦姿勢に装着され、防塵フィルタ１９はクロスフローファン２１と接触しないように上部が下部に対して前側に傾斜している。吸込口１８及び防塵フィルタ１９の前方側を覆うように、前パネル２３がハウジング１に固定されて垂下されている。前パネル２３は吸込口１８の形状に合わせて正面視で下縁部の中央部が下側に凸状をなし、又、中央部が前側に突き出るように左右方向に湾曲している。 A dust-proof filter 19 is attached to the suction port 18 in a vertical position, and the upper part of the dust-proof filter 19 is inclined forward with respect to the lower part so as not to contact the cross flow fan 21. A front panel 23 is fixed to the housing 1 and suspended so as to cover the front side of the suction port 18 and the dust filter 19. The front panel 23 is curved in the left-right direction so that the central portion of the lower edge portion protrudes downward and the central portion protrudes to the front side in front view according to the shape of the suction port 18.
　通風路２０のクロスフローファン２１と吹出口１７との間の壁面に、正負のイオンを発生させるイオン発生器２２が配設されている。イオン発生器２２には、針状の放電電極（不図示）が風路内に露出するように設けられ、放電電極に給電部（不図示）から交流波形またはインパルス波形の電圧を供給することによって放電電極がイオンを発生する。 An ion generator 22 that generates positive and negative ions is disposed on the wall surface between the cross flow fan 21 and the outlet 17 of the ventilation path 20. The ion generator 22 is provided with a needle-like discharge electrode (not shown) so as to be exposed in the air path, and an AC waveform or impulse waveform voltage is supplied to the discharge electrode from a power feeding unit (not shown). The discharge electrode generates ions.
　クロスフローファン２１のモータ２１ａ及びイオン発生器２２が駆動されると、クロスフローファン２１によって吹出口１７から吸い込まれた空気に、イオン発生器２２により発生したイオンが付加され、イオンを含む空気が吹出口１７より前方側に吹き出される。 When the motor 21a and the ion generator 22 of the crossflow fan 21 are driven, the ions generated by the ion generator 22 are added to the air sucked from the outlet 17 by the crossflow fan 21, and the air containing the ions is The air is blown forward from the air outlet 17.
　放電電極の印加電圧が正電圧の場合はイオンが空気中の水分と結合して主としてＨ+（ Ｈ2Ｏ）m から成るプラスイオンを発生する。放電電極の印加電圧が負電圧の場合はイオンが空気中の水分と結合して主としてＯ2 -（Ｈ2Ｏ）n から成るマイナスイオンを発生する。ここで、ｍ、ｎは任意の自然数である。Ｈ+（ Ｈ2Ｏ）m 及びＯ2 -（Ｈ2Ｏ）nは空気中の浮遊菌や臭い成分の表面で凝集してこれらを取り囲む。 When the voltage applied to the discharge electrode is a positive voltage, ions combine with moisture in the air to generate positive ions mainly composed of H + (H 2 O) m . When the voltage applied to the discharge electrode is a negative voltage, the ions are combined with moisture in the air to generate negative ions mainly composed of O 2 − (H 2 O) n . Here, m and n are arbitrary natural numbers. H + (H 2 O) m and O 2 − (H 2 O) n aggregate on the surface of airborne bacteria and odorous components and surround them.

Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, sterilization and odor removal in the vicinity of the user can be performed by generating positive ions and negative ions and discharging them from the outlet 17.

　ハウジング１は、風路カバー１２の前側を覆う前カバー１６を前面下部に備えている。前カバー１６は上部に上部側ほど後方に緩やかに傾斜した上傾斜面１６ａを有する。前カバー１６は下端部に横方向に伸びる凹溝部１６ｃを有し、凹溝部１６ｃの底部は開口している。凹溝部１６ｃの上側斜面が下部側ほど後方に急傾斜した下傾斜面１６ｂを形成している。 The housing 1 is provided with a front cover 16 covering the front side of the air passage cover 12 at the lower part of the front surface. The front cover 16 has an upper inclined surface 16a which is gently inclined backward toward the upper side at the upper part. The front cover 16 has a groove 16c extending in the lateral direction at the lower end, and the bottom of the groove 16c is open. The upper inclined surface of the recessed groove portion 16c forms a lower inclined surface 16b that is steeper rearward toward the lower side.
　ハウジング１の底面には、ロック機構付きの複数の車輪９が取り付けてある。これにより、車輪９のロック機構を解除して空気清浄機を室内の適所に移動させた後、ロック機構を作動させて空気清浄機を床上で移動しない状態で設置することができる。 A plurality of wheels 9 with a lock mechanism are attached to the bottom surface of the housing 1. Thereby, after releasing the lock mechanism of the wheel 9 and moving the air cleaner to an appropriate place in the room, the lock mechanism can be operated to install the air cleaner without moving on the floor.
　次に以上の如き構成の空気清浄機による空気の流れについて説明する。空気清浄機は壁Ｗ際の床面Ｆに設置してある。上面の吹出口１５から斜め後方上向きに吹き出された清浄空気は背側の壁Ｗ、天井及び向かい側の壁（不図示）を経て室内を循環した後、空気清浄機の前面側に戻り、前カバー１６に当たる。前カバー１６の上側部分に当たった空気は上傾斜面１６ａに沿って流れ、前パネル２３と上傾斜面１６ａとの間隙を通ってイオン用の吸込口１８に吸引される。吸込口１８に吸引された空気は防塵フィルタ１９にて埃が除去され、通風路２０を流れるときにイオンを付加され、吹出口１７から前方側に吹き出される。尚、吹出口１７から前方側に吹き出された空気も循環して空気清浄機の前面側に戻る。 Next, the flow of air by the air cleaner configured as described above will be described.

The air hitting the upper portion of the front cover 16 flows along the upper inclined surface 16a, and is sucked into the ion suction port 18 through the gap between the front panel 23 and the upper inclined surface 16a. Dust is removed from the air sucked into the suction port 18 by the dust filter 19, ions are added when flowing through the ventilation path 20, and the air is blown forward from the air outlet 17. Note that air blown forward from the outlet 17 also circulates and returns to the front side of the air purifier.
　一方、前カバー１６の下側部分に当たった空気は凹溝部１６ｃに入って下傾斜面１６ｂに沿って流れ、さらに底面と床面Ｆとの間を流れて背面側に達し、吸込口２ａに吸引される。吸込口２ａに吸引された空気は脱臭フィルタ７ａ、集塵フィルタ７ｂ及び加湿フィルタユニット３を通過して浄化及び加湿され（又は加湿されず）、上面の吹出口１５から吹き出される。以下、このような空気の循環を繰り返す。 On the other hand, the air hitting the lower part of the front cover 16 enters the concave groove 16c and flows along the lower inclined surface 16b, further flows between the bottom surface and the floor surface F, reaches the back surface side, and enters the suction port 2a. Sucked. The air sucked into the suction port 2a passes through the deodorizing filter 7a, the dust collection filter 7b, and the humidification filter unit 3 to be purified and humidified (or not humidified), and is blown out from the air outlet 15 on the upper surface. Hereinafter, such air circulation is repeated.
　本発明において、発生させるイオンは帯電微粒子水も含むものとする。この時、イオン発生器は静電霧化装置から成り、静電霧化装置によってラジカル成分を含む帯電微粒子水が生成される。即ち、静電霧化装置に設けた放電電極をペルチェ素子により冷却することで放電電極の表面に結露水が生じる。次に、放電電極にマイナスの高電圧を印加すると、結露水から帯電微粒子水が生成される。また、放電電極からは帯電微粒子水とともに空気中に放出されるマイナスイオンも発生する。 In the present invention, the generated ions include charged fine particle water. At this time, the ion generator includes an electrostatic atomizer, and charged fine particle water containing a radical component is generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. In addition, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.
　上記の実施の形態では、横長の吹出口１７を略長円又は楕円形状にして、上下幅が広い中央部から端部側に向かって連続的に狭くなるようにしたが、これ以外に、例えば上下幅が中央部から端部側に向かって段階的に狭くなるようにしてもよい。 In the above embodiment, the horizontally long air outlet 17 is formed into a substantially oval or elliptical shape so as to be continuously narrowed from the central portion having a large vertical width toward the end portion side. You may make it an up-down width | variety narrow in steps toward an edge part side from a center part.
　上記の実施の形態では、通風路２０には防塵フィルタ１９のみを配したが、浄化能力を高めるために、脱臭フィルタ７ａ及び集塵フィルタ７ｂと同様の脱臭フィルタ及び集塵フィルタを配置してもよい。 In the above embodiment, only the dust filter 19 is disposed in the ventilation path 20, but in order to improve the purification capability, a deodorization filter and a dust collection filter similar to the deodorization filter 7a and the dust collection filter 7b may be arranged. Good.
　なお、今回開示した実施の形態は、全ての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は、請求の範囲内での全ての変更及び請求の範囲と均等の範囲が含まれることが意図される。 It should be noted that the embodiment disclosed herein is illustrative in all respects and is not restrictive.
