従来、この種の加湿装置は、気化フィルタに空気を接触させて加湿を行うものが知られている(例えば、特許文献1参照)。   Conventionally, this type of humidifier is known to perform humidification by bringing air into contact with a vaporization filter (see, for example, Patent Document 1).

以下、その加湿装置について図6を参照しながら説明する。   Hereinafter, the humidifier will be described with reference to FIG.

図6に示すように、加湿装置101は、加湿装置101の吸込口102から吸込んだ空気を上面吹出口103、側面吹出口104に送る送風手段105と、前記送風手段105により送られた空気を加湿する気化フィルタ106とを備え、前記上面吹出口103、側面吹出口104は、それぞれ前記上面吹出口103は加湿装置101の上面に、前記側面吹出口104は加湿装置101の側面に形成されている。送風手段105によって吸込口102から吸い込んだ空気を、水を吸上げ湿潤した気化フィルタ106に通過させ、前記上面吹出口103、側面吹出口104から加湿空気を得るものである。   As shown in FIG. 6, the humidifier 101 includes a blowing unit 105 that sends air sucked from the suction port 102 of the humidifying device 101 to the top outlet 103 and the side outlet 104, and the air sent by the blowing unit 105.

このような従来の加湿装置では、加湿空気を吹出す吹出口を加湿装置の上面と側面とに夫々設けているので、加湿装置の上面から加湿空気を吹出すのみならず、加湿装置の側面からも加湿空気を吹出すので、加湿装置の周囲の湿度を所望の湿度に上げることができる。しかし、冬場はエアコンなどの暖房器具を使用することが多く、その場合には部屋の天井付近と床付近では温度差が生じ、卓上や床に置いて使用する従来の加湿装置では床付近の加湿はすばやくできるものの、天井付近には吹出した加湿空気が届かないため加湿に時間がかかり、部屋全体を均一に加湿するのに長い時間がかかるという課題があった。   In such a conventional humidifier, since the outlet for blowing the humidified air is provided on each of the upper surface and the side surface of the humidifier, not only the humidified air is blown from the upper surface of the humidifier, but also from the side surface of the humidifier. Since the humidified air is blown out, the humidity around the humidifier can be raised to a desired humidity. However, in winter, heating equipment such as an air conditioner is often used. In that case, there is a temperature difference between the ceiling of the room and the floor, and conventional humidifiers that are used on a desktop or floor use a humidifier near the floor. Although it can be done quickly, it takes time to humidify because the humidified air that has blown out does not reach the vicinity of the ceiling, and it takes a long time to uniformly humidify the entire room.

本発明の請求項1記載の加湿装置は、下部に空気を取り入れる吸込口と、上部に空気を上方へ吹出す吹出口とを設けた筐体に、高圧空気を発生するための羽根車と前記羽根車を駆動するためのモータで構成された高圧空気発生手段と、前記吸込口と前記羽根車の間に設けた気化フィルタと、前記気化フィルタに水を供給する加湿トレイとを備え、前記羽根車と前記吹出口の間に、前記羽根車で発生した高圧空気を直進旋回流に変換する直進旋回流変換手段を設け、前記直進旋回流変換手段は、前記羽根車から前記吹出口までの送風路を構成する高圧空気集約板と静翼とを備え、前記高圧空気集約板に囲まれた前記送風路の水平方向の断面積が前記羽根車側から前記吹出口に近づくにつれ小さくなることを特徴とするものである。ここで、高圧空気とは大気圧以上、大気圧プラス1kPa以下の空気を示すものとする。なお、直進旋回流とは強い直進成分と旋回成分を伴った空気流を示すものである。 The humidifying device according to claim 1 of the present invention includes an impeller for generating high-pressure air in a housing provided with a suction port for taking in air at a lower portion and a blow-out port for blowing air upward at an upper portion. A high-pressure air generating means comprising a motor for driving the impeller, a vaporization filter provided between the suction port and the impeller, and a humidifying tray for supplying water to the vaporization filter, the vane A rectilinear swirl flow converting means for converting high-pressure air generated in the impeller into a rectilinear swirl flow is provided between the car and the blower outlet, and the rectilinear swirl flow converting means is configured to send air from the impeller to the blower outlet. A high-pressure air collecting plate and a stationary blade constituting the path, wherein the horizontal cross-sectional area of the air passage surrounded by the high-pressure air collecting plate is reduced as it approaches the air outlet from the impeller side. It is what. Here, high-pressure air refers to air having an atmospheric pressure or higher and an atmospheric pressure plus 1 kPa or lower. Note that the straight-forward swirling flow indicates an air flow accompanied by a strong straight-running component and a swirling component.

これにより、吹出口から吹出される加湿された高圧空気は、直進旋回流変換手段により直進する成分を伴った旋回流となって天井方向に吹出されるため、直進性に優れ、遠方まで風速の減衰が少なく加湿された高圧空気を送り届けることができ、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できるものである。ここで、吹出される高圧空気は、気化フィルタにより加湿されているため加湿装置周囲の空気より比重が大きいため、加湿装置周囲の比重の小さい空気を効率よく巻き込むことができる。これにより、冬場にエアコンなどの暖房器具を使用し、部屋の天井付近と床付近では温度差が生じる場合、加湿装置周囲の冷たい空気も加湿された空気と共に天井付近に送ることができ、部屋全体の温度、湿度共に素早く均一にすることができる。   As a result, the humidified high-pressure air blown out from the air outlet is blown in the ceiling direction as a swirl flow accompanied by a component that travels straight by the straight swirl flow conversion means, and thus is excellent in straight travel and has a wind speed of far away. It is possible to deliver humidified high-pressure air with little attenuation, and efficiently deliver humidified air to the vicinity of the ceiling even when placed on a tabletop or floor, enabling quick and even humidification of the entire room. . Here, since the high-pressure air that is blown out is humidified by the vaporization filter, the specific gravity is larger than the air around the humidifying device, so that air with a small specific gravity around the humidifying device can be efficiently entrained. This makes it possible to use a heater such as an air conditioner in the winter, and if there is a temperature difference between the ceiling and floor of the room, the cold air around the humidifier can be sent to the ceiling along with the humidified air. The temperature and humidity can be made uniform quickly.

また、直進旋回流変換手段が、羽根車から吹出口までの送風路を構成する高圧空気集約板と、水平断面が円弧状の複数の静翼からなり、前記高圧空気集約板に囲まれた前記送風路の水平方向の断面積が前記羽根車側から前記吹出口に近づくにつれ小さくなることを特徴とするもので、直進旋回流に変換するために高圧空気発生手段以外に電力を消費する手段を設ける必要がないため、省エネで直進性に優れ、遠方まで風速の減衰が少なく加湿された高圧空気を送り届けることができ、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できる。   Further, the straight-forward swirl flow converting means is composed of a high-pressure air collecting plate that constitutes an air passage from the impeller to the blower outlet, and a plurality of stationary blades having a horizontal cross section in an arc shape, and is surrounded by the high-pressure air collecting plate. The horizontal cross-sectional area of the air passage becomes smaller as it approaches the blower outlet from the impeller side, and means for consuming electric power in addition to the high-pressure air generating means for conversion into a straight-forward swirl flow Since there is no need to install it, it is energy-saving, has excellent straightness, can deliver high-pressure air that has been humidified with little attenuation of wind speed far away, and even when used on a desktop or floor, it can efficiently deliver humidified air to the vicinity of the ceiling. Deliver and quickly and uniformly humidify the entire room.

また、羽根車がターボファンであることを特徴とするもので、ターボファンであれば、羽根車表面に埃などの汚れが蓄積することを抑制できるため、加湿された空気により、埃などの汚れが堆積し、性能が低下することを抑制でき、長期間安定して加湿を行うことができる。また、ターボファンであれば、等しく全周に高圧空気を吹出すことができるため、直進旋回流変換手段に圧力ムラの少ない高圧空気を送ることができ、高圧空気を効率よく直進旋回流に変換することができる。   In addition, the impeller is a turbo fan, and if it is a turbo fan, it is possible to suppress accumulation of dirt such as dust on the surface of the impeller. It can suppress that performance accumulates and a performance falls, and can humidify stably for a long period of time. In addition, since a turbo fan can blow high-pressure air equally around the entire circumference, high-pressure air with little pressure unevenness can be sent to the straight-forward swirl flow conversion means, and high-pressure air is efficiently converted to straight swirl flow. can do.

また、吹出口の中心がターボファンの回転軸上に備えられたことを特徴とするもので、ターボファンであれば、等しく全周に高圧空気を吹出すことができ、吹出口の中心がターボファンの回転軸上であれば、ターボファンから直進旋回流変換手段に圧力ムラの少ない高圧空気が供給されるため、直進旋回流変換手段で効率よく高圧空気を直進旋回流に変換でき、天井方向に直進旋回流を吹出すことができる。これにより、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できる。   In addition, the center of the blowout port is provided on the rotating shaft of the turbofan, and if it is a turbofan, high-pressure air can be blown out all around, and the center of the blowout port is at the turbo If it is on the rotation axis of the fan, high-pressure air with little pressure unevenness is supplied from the turbo fan to the straight-forward swirl flow conversion means, so that the high-speed air can be efficiently converted into straight swirl flow by the straight-forward swirl flow conversion means. A straight swirl flow can be blown out. As a result, even when used on a desktop or floor, it is possible to efficiently deliver humidified air to the vicinity of the ceiling and quickly and uniformly humidify the entire room.

また、請求項1乃至4いずれかに記載の加湿装置の気化フィルタの上流側に、空気浄化フィルタを設けたことを特徴とする加湿機能付空気清浄装置であり、空気浄化フィルタにより浄化された空気を気化フィルタに送ることができるため、気化フィルタが汚染されることを抑制することができ、気化フィルタに菌やカビが繁殖するのを抑制することができる。また、吹出口から上方に吹出される加湿された高圧空気は、直進旋回流変換手段により直進旋回流となって天井方向に吹出されるため、直進性に優れ、遠方まで風速の減衰が少なく加湿された高圧空気を送り届けることができ、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できるものである。   An air cleaning device with a humidifying function, characterized in that an air purification filter is provided upstream of the vaporization filter of the humidification device according to any one of claims 1 to 4, wherein the air purified by the air purification filter Can be sent to the vaporization filter, so that the vaporization filter can be prevented from being contaminated, and fungi and mold can be prevented from breeding on the vaporization filter. In addition, the humidified high-pressure air blown upward from the air outlet is converted into a straight-forward swirl flow by the straight swirl flow conversion means and is blown toward the ceiling. The high-pressure air can be delivered, and even when used on a desktop or floor, humidified air can be efficiently delivered to the vicinity of the ceiling, and the entire room can be humidified quickly and uniformly.

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

(実施の形態1)
図1は加湿装置11の斜視図、図2は図1の断面Xでの断面を示す構成図、図3は加湿装置11の分解斜視図、図4は直進旋回流変換手段の斜視図である。
(Embodiment 1)
FIG. 1 is a perspective view of the humidifier 11, FIG. 2 is a configuration diagram showing a cross section along the section X of FIG. 1, FIG. 3 is an exploded perspective view of the humidifier 11, and FIG. .

図1、図2、図3および図4に示すように、加湿装置11は、下部に空気を取り入れる吸込口12と、上部に空気を吹出す吹出口13とを設けた筐体14に、高圧空気を発生するための羽根車としてのターボファン15とターボファン15を駆動するためのモータ16で構成された高圧空気発生手段17と、吸込口12とターボファン15の間に設けた気化フィルタ18と、気化フィルタ18に水を供給する加湿トレイ19とを備え、ターボファン15と吹出口13の間に、ターボファン15で発生した高圧空気を直進旋回流に変換する直進旋回流変換手段20を備えるものである。ここで、高圧空気とは大気圧以上、大気圧プラス1kPa以下の空気を示すものとする。   As shown in FIGS. 1, 2, 3, and 4, the humidifying device 11 has a high pressure in a housing 14 provided with a suction port 12 for taking in air at a lower portion and a blower outlet 13 for blowing out air at an upper portion. A turbo fan 15 as an impeller for generating air, a high-pressure air generating means 17 composed of a motor 16 for driving the turbo fan 15, and a vaporization filter 18 provided between the suction port 12 and the turbo fan 15. And a humidifying tray 19 for supplying water to the vaporizing filter 18, and a straight swirl flow conversion means 20 for converting high-pressure air generated by the turbo fan 15 into a straight swirl flow between the turbo fan 15 and the outlet 13. It is to be prepared. Here, the high-pressure air refers to air having an atmospheric pressure or higher and an atmospheric pressure plus 1 kPa or lower.

また、加湿装置11には加湿により加湿トレイ19の水が減少した際に水を補給するための水タンク21が筐体14側面に着脱可能に設けられている。筐体14側面には水タンク支持枠24が備えられており、水タンク支持枠24で形成された枠内に水タンク21を挿入することで、加湿トレイ19と水タンク支持枠24により保持されるため、水タンク21を定位置に設置できる構成となっている。なお、本実施形態では水タンク21を備えた加湿装置11を示したが、水タンク21を設けず、加湿トレイ19に直接給水する仕様であってもよい。   Further, the humidifier 11 is provided with a water tank 21 detachably attached to the side surface of the housing 14 for replenishing water when the water in the humidifying tray 19 decreases due to humidification. A water tank support frame 24 is provided on the side surface of the housing 14, and the water tank 21 is inserted into a frame formed by the water tank support frame 24, thereby being held by the humidifying tray 19 and the water tank support frame 24. Therefore, the water tank 21 can be installed at a fixed position. In addition, although the humidification apparatus 11 provided with the water tank 21 was shown in this embodiment, the specification which supplies water directly to the humidification tray 19 without providing the water tank 21 may be sufficient.

また、直進旋回流変換手段20はターボファン15から吹出口13までの送風路25を構成する略円筒状の高圧空気集約板22と、水平断面が円弧状で略鉛直方向に設けた複数(本実施形態では7枚)の静翼23からなり、高圧空気集約板22に囲まれた送風路25の水平方向の断面積がターボファン15側から吹出口13に近づくにつれ小さくなるよう構成されている。また、吹出口13の中心はターボファン15の回転軸上に備えられた構成である。   Further, the rectilinear swirl flow converting means 20 includes a substantially cylindrical high-pressure air collecting plate 22 that constitutes an air passage 25 from the turbo fan 15 to the outlet 13, and a plurality of (this book) provided with a horizontal section in an arc shape and a substantially vertical direction. 7 in the embodiment), and the horizontal cross-sectional area of the air passage 25 surrounded by the high-pressure air collecting plate 22 is configured to become smaller as it approaches the air outlet 13 from the turbofan 15 side. . The center of the air outlet 13 is provided on the rotating shaft of the turbo fan 15.

静翼23の枚数としては3枚以上15枚以下が高圧空気を直進旋回流に効率よく変換でき、かつ静翼23が高圧空気が通過する際の通風抵抗になることを抑えることができるため好ましく、本実施形態では説明しない、他の構成部材、例えばターボファン15近傍に設けた配線用の管路(保護カバー)の個数との関連(同じまたは倍数なら共振等の発生)から静翼23の枚数は素数が好ましい。   The number of the stationary blades 23 is preferably 3 or more and 15 or less because high-pressure air can be efficiently converted into a straight-forward swirl flow, and the stationary blade 23 can be prevented from becoming a ventilation resistance when high-pressure air passes. From the relationship with the number of other structural members, for example, the number of conduits (protective covers) for wiring provided in the vicinity of the turbofan 15 (which is the same or multiple, the occurrence of resonance, etc.) not described in the present embodiment. The number of sheets is preferably a prime number.

さらに本実施形態のようにターボファン15を用いる場合にはターボファン15の羽根枚数(本実施形態では9枚)に対して最小公倍数がなるべく大きくなる静翼23の枚数とすることが、ターボファン15が回転することによる羽根枚数と静翼23の干渉音を少なくすることができるため好ましく、本実施形態では静翼23の枚数を7枚としている。   Further, when the turbo fan 15 is used as in the present embodiment, the number of the stationary blades 23 is as large as possible with respect to the number of blades of the turbo fan 15 (9 in the present embodiment). The number of blades and the interference sound of the stationary blades 23 due to the rotation of the blades 15 can be reduced. In this embodiment, the number of stationary blades 23 is seven.

このような構成によれば、ターボファン15で発生した高圧空気は、強い遠心力を伴った旋回成分と、ターボファン15直後の高圧と吹出口13外部の大気圧の差圧により弱い上向きの直流成分をもったものである。この強い遠心力を伴った旋回成分と弱い上向きの直流成分をもった高圧空気は、直進旋回流変換手段20の吹出口13に近づくにつれ送風路25の水平方向の断面積の小さくなる高圧空気集約板22により吹出口13に集約されつつ、水平断面が円弧状の複数の静翼23により強い遠心力を伴った旋回成分は徐々に上向きの直流成分に変換される。   According to such a configuration, the high-pressure air generated in the turbo fan 15 is weakly upward direct current due to the swirling component accompanied by a strong centrifugal force and the differential pressure between the high pressure immediately after the turbo fan 15 and the atmospheric pressure outside the blower outlet 13. It has ingredients. The high-pressure air having a swirling component with strong centrifugal force and a weak upward direct current component has a high-pressure air concentration in which the cross-sectional area in the horizontal direction of the air passage 25 decreases as it approaches the outlet 13 of the straight-forward swirling flow converting means 20. A swirl component accompanied by a strong centrifugal force is gradually converted into an upward direct current component by a plurality of stationary blades 23 whose horizontal cross section is arcuate while being concentrated on the air outlet 13 by the plate 22.

そして吹出口13から吹出される際には、直進性に優れた、強い上向きの直流成分からなる直進旋回流となるものである。これにより、吹出口13から吹出される加湿された高圧空気は、直進旋回流変換手段20により直進旋回流(図1中実線矢印)となって天井方向に吹出されるため、直進性に優れ、遠方まで風速の減衰が少なく加湿された高圧空気を送り届けることができる。   And when it blows off from the blower outlet 13, it becomes the straight-forward turning flow which consists of a strong upward direct current | flow component excellent in straightness. Thereby, the humidified high-pressure air blown out from the outlet 13 is straightly swirled (solid arrow in FIG. 1) and blown out toward the ceiling by the straight swirling flow conversion means 20, and thus has excellent straightness. It is possible to deliver humidified high-pressure air with little attenuation of wind speed far away.

さらに詳細に説明すると、図4に示すように静翼23は加湿装置11の上方から見たときに円弧状でターボファン15の回転軸方向にはひねりのない形状となっている。本実施形態での高圧空気集約板22と静翼23においては、ターボファン15の回転軸付近では静翼23はひねりが無いため高圧空気を直流成分に変換するのに寄与し、高圧空気集約板22近傍では、高圧空気集約板22が吹出口13に近づくにつれ送風路25の水平方向の断面積が小さくなるとともに、円弧状の静翼23が吹出口13に近づくにつれひねられる構成により高圧空気に適度な旋回成分が与えられるものである。さらにこのような構成であれば、金型を単純に上下から抜ける構成のため製造が容易である。   More specifically, as shown in FIG. 4, the stationary blade 23 has an arc shape when viewed from above the humidifier 11 and has a shape without a twist in the direction of the rotation axis of the turbofan 15. In the high-pressure air collecting plate 22 and the stationary blade 23 in the present embodiment, the stationary blade 23 has no twist near the rotating shaft of the turbofan 15 and contributes to converting high-pressure air into a direct current component. In the vicinity of 22, the horizontal cross-sectional area of the air passage 25 decreases as the high-pressure air collecting plate 22 approaches the air outlet 13, and the arc-shaped stationary blade 23 is twisted as it approaches the air outlet 13. A moderate swirl component is given. Further, with such a configuration, the mold can be easily manufactured because the mold can be simply pulled out from above and below.

これにより、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できるものである。このとき、直進旋回流に変換するために高圧空気発生手段17以外に電力を消費する手段を設ける必要がなく、省エネである。   As a result, even when used on a desktop or floor, humidified air can be efficiently delivered to the vicinity of the ceiling, and the entire room can be humidified quickly and uniformly. At this time, it is not necessary to provide a means for consuming electric power other than the high-pressure air generating means 17 in order to convert it into a straight-forward swirling flow, which saves energy.

ここで、吹出される高圧空気は、気化フィルタ18により加湿されているため加湿装置11周囲の空気より比重が大きいため、加湿装置11周囲の比重の小さい空気を効率よく巻き込む(図1中点線矢印)ことができるため、冬場にエアコンなどの暖房器具を使用し、部屋の天井付近と床付近では温度差が生じる場合、加湿装置11周囲の冷たい空気も加湿された空気と共に天井付近に送ることができ、部屋全体の温度、湿度共に素早く均一にすることができる。   Here, since the high-pressure air that is blown out is humidified by the vaporization filter 18, the specific gravity is larger than the air around the humidifying device 11, so that the air having a small specific gravity around the humidifying device 11 is efficiently involved (dotted line arrow in FIG. 1). Therefore, when a heater such as an air conditioner is used in winter and a temperature difference occurs between the ceiling and the floor of the room, the cool air around the humidifier 11 can be sent to the ceiling together with the humidified air. The temperature and humidity of the entire room can be made uniform quickly.

また、羽根車にはターボファン15を用いており、羽根車表面に埃などの汚れが蓄積することを抑制できるため、加湿された空気により、埃などの汚れが堆積し、性能が低下することを抑制でき、長期間安定して加湿を行うことができる。また、ターボファン15であれば、等しく全周に高圧空気を吹出すことができるため、直進旋回流変換手段20に圧力ムラの少ない高圧空気を送ることができ、高圧空気を効率よく直進旋回流に変換することができる。   In addition, since the impeller uses a turbo fan 15, it is possible to suppress the accumulation of dirt such as dust on the surface of the impeller, so that dirt such as dust accumulates due to humidified air, resulting in reduced performance. And can be stably humidified for a long period of time. Further, since the turbo fan 15 can equally blow high-pressure air around the entire circumference, high-pressure air with little pressure unevenness can be sent to the straight-forward swirl flow converting means 20, and the high-pressure air can be efficiently swept straight. Can be converted to

なお、高圧空気発生手段17の羽根車として、本実施形態ではターボファン15を記載したが、静圧が大きく取れる羽根車、例えばシロッコファンといった遠心ファンも使用可能である。   In addition, although the turbo fan 15 was described in this embodiment as an impeller of the high pressure air generation means 17, the impeller which can take a large static pressure, for example, centrifugal fans, such as a sirocco fan, can also be used.

また、このように上向きの吹出し方向に対して垂直方向に遠心力を伴った高圧空気を発生しない種類の羽根車(例えばシロッコファンのケーシング吹出しを上向きにして用いるなど)を用いる場合には、本実施形態よりわずかに強く旋回成分を与えることが好ましいため、直進旋回流変換手段20の静翼23として、プロペラファンのような形状にすることで静翼23で適度な旋回成分を与えることができる。   In addition, when using an impeller of a type that does not generate high-pressure air with centrifugal force in a direction perpendicular to the upward blowing direction (for example, the casing blowing of a sirocco fan is used upward) Since it is preferable to give a swirl component slightly stronger than that of the embodiment, an appropriate swirl component can be given to the stationary blade 23 by forming it as a propeller fan as the stationary blade 23 of the rectilinear swirl flow converting means 20. .

(Embodiment 2)
FIG. 5 is an exploded perspective view of the air cleaning device 31 with a humidifying function.

図5において、加湿機能付空気清浄装置31は図1、図2、図3および図4に示した加湿装置11の吸込口12と気化フィルタ18の間に空気浄化フィルタ32を設けた構成となっており、図1、図2および図3と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。   In FIG. 5, the air purification device 31 with a humidifying function has a configuration in which an air purification filter 32 is provided between the suction port 12 and the vaporization filter 18 of the humidification device 11 shown in FIGS. 1, 2, 3, and 4. Components similar to those in FIGS. 1, 2, and 3 are given the same reference numerals, and detailed descriptions thereof are omitted.

ここで、空気浄化フィルタ32は集塵フィルタまたは/および脱臭フィルタで構成されている。   Here, the air purification filter 32 is configured by a dust collection filter and / or a deodorization filter.

このような構成によれば、空気浄化フィルタ32により浄化された空気を気化フィルタ18に送ることができるため、気化フィルタ18が汚染されることを抑制することができ、気化フィルタ18に菌やカビが繁殖するのを抑制することができる。また、吹出口13から吹出される加湿された高圧空気は、直進旋回流変換手段20により直進旋回流となって天井方向に吹出されるため、直進性に優れ、遠方まで風速の減衰が少なく加湿された高圧空気を送り届けることができ、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿することを実現できるものである。ここで、吹出される高圧空気は、気化フィルタ18により加湿されているため加湿機能付空気清浄装置31周囲の空気より比重が大きいため、加湿機能付空気清浄装置31周囲の比重の小さい空気を効率よく巻き込むことができる。これにより、冬場にエアコンなどの暖房器具を使用し、部屋の天井付近と床付近では温度差が生じる場合、加湿機能付空気清浄装置31周囲の冷たい空気も加湿された空気と共に天井付近に送ることができるため、部屋全体の温度、湿度共に素早く均一にすることができる。   According to such a configuration, since the air purified by the air purification filter 32 can be sent to the vaporization filter 18, it is possible to suppress the vaporization filter 18 from being contaminated. Can be prevented from breeding. Further, the humidified high-pressure air blown out from the outlet 13 is converted into a straight-forward swirl flow by the straight swirl flow conversion means 20 and is blown toward the ceiling. The high-pressure air can be delivered, and even when used on a desktop or floor, humidified air can be efficiently delivered to the vicinity of the ceiling, and the entire room can be humidified quickly and uniformly. Here, since the high-pressure air that is blown out is humidified by the vaporization filter 18, the specific gravity is larger than the air around the air purifying device 31 with the humidifying function, so that the air with a small specific gravity around the air purifying device 31 with the humidifying function is efficiently used. Can be involved well. In this way, when using a heater such as an air conditioner in the winter, and there is a temperature difference between the ceiling and the floor of the room, the cool air around the humidifying air purifier 31 is also sent to the ceiling along with the humidified air. Therefore, the temperature and humidity of the entire room can be made uniform quickly.

また、空気浄化フィルタ32が、集塵フィルタまたは/および脱臭フィルタを含むことで、これにより空気浄化フィルタ32を高圧空気が通過することで、空気中に含まれる塵や菌、カビ、臭気成分を取り除くことができる。   Further, since the air purification filter 32 includes a dust collection filter and / or a deodorization filter, high-pressure air passes through the air purification filter 32, thereby removing dust, fungi, mold, and odor components contained in the air. Can be removed.

本発明にかかる加湿装置および加湿機能付空気清浄装置は、卓上や床に置いて使用しても天井付近にまで加湿空気を効率よく送り届け、部屋全体を素早く均一に加湿可能な加湿装置および加湿機能付空気清浄装置を提供できるため、居室内の床、卓上に設置される加湿装置および加湿機能付空気清浄装置などに利用できる。   The humidifying device and the air cleaning device with a humidifying function according to the present invention efficiently deliver humidified air to the vicinity of the ceiling even when used on a desk or floor, and a humidifying device and a humidifying function capable of quickly and uniformly humidifying the entire room. Since an air-cleaning device with an air can be provided, it can be used for a floor in a living room, a humidifier installed on a table, an air cleaner with a humidifying function, and the like.
