Description

空気清浄機Air cleaner
　本発明は、送風装置により本体内部へと吸込んだ室内空気を、脱臭部に通すことで空気中の臭気成分を取り除き、室内空気の脱臭を行う空気清浄機に関する。 The present invention relates to an air cleaner that removes odorous components in the air by passing indoor air sucked into the main body by a blower through a deodorizing unit and deodorizes the indoor air.
　従来から、本体ケースと、この本体ケースの前面に形成された空気吸込口と、本体ケースの上面後部に形成された空気吹出口と、本体ケース内に設けられ、空気吸込口から空気を吸い込んで空気吹出口へ吹き出すためのファンと、このファンを駆動するためのファンモータと、ファンの上流側に設けられ、吸い込まれた空気中の塵埃を捕集するための集塵フィルターとを備え、空気吹出口の近傍に、臭気成分を吸着するための吸着材の表面に触媒を添着してなる脱臭部と、この脱臭部の脱臭機能を回復するために加熱する加熱部を有する空気清浄機がある。 Conventionally, a main body case, an air inlet port formed on the front surface of the main body case, an air outlet port formed on the rear surface of the upper surface of the main body case, and provided in the main body case for sucking air from the air inlet port. A fan for blowing out to the air outlet, a fan motor for driving the fan, and a dust collecting filter provided on the upstream side of the fan for collecting dust in the sucked air; There is an air cleaner having a deodorizing part formed by adhering a catalyst to the surface of an adsorbent for adsorbing odorous components and a heating part for heating to recover the deodorizing function of the deodorizing part in the vicinity of the blowout port. .
　このような空気清浄機は、ファンを駆動することにより、空気吸込口から本体ケース内部に室内空気を取り込み、集塵フィルターにて塵埃を除去した後、脱臭部に流下した室内空気中の臭気成分が、脱臭部の吸着材に吸着することにより、室内空気の脱臭を行う。
　そして、臭気を吸着した脱臭部の吸着材は、加熱部により加熱されることで、臭気成分が除去されて、脱臭機能を回復させることができる（例えば、特許文献１）。 Such an air purifier takes in indoor air from the air inlet into the main body case by driving a fan, removes dust with a dust collecting filter, and then flows down to the deodorizing part in the indoor air. However, the indoor air is deodorized by adsorbing to the adsorbent of the deodorizing part.
And the adsorbent of the deodorizing part which adsorb | sucked the odor is heated by a heating part, an odor component is removed, and a deodorizing function can be recovered (for example, patent document 1).
日本特開２００１－３８１２６号公報（図１）Japanese Unexamined Patent Publication No. 2001-38126 (FIG. 1)
　しかしながら、先行技術文献に記載の空気清浄機は、本体ケースの上面後部に形成された空気吹出口の近傍に、臭気成分を吸着するための吸着材を有する脱臭部を設けることから、大変狭い限られた領域に脱臭部を配置する必要があり、より脱臭性能の高い脱臭容量の大きい臭気の吸着材を用いることが困難である。
　従って、このような構造では、脱臭部に室内空気を通過させても、一度に大幅に臭気を除去することが困難であることから、人が室内空気の臭気が減少したと感じることができるようになるまで、長い時間の間、空気清浄機を運転する必要がある。 However, the air cleaner described in the prior art document is provided with a deodorizing part having an adsorbent for adsorbing odorous components in the vicinity of the air outlet formed at the upper rear part of the main body case. It is necessary to dispose a deodorizing part in the area, and it is difficult to use an adsorbent of odor with higher deodorizing performance and larger deodorizing capacity.
Therefore, in such a structure, even if room air is passed through the deodorizing part, it is difficult to remove the odor significantly at a time, so that a person can feel that the odor of the room air has decreased. It is necessary to operate the air cleaner for a long time until it becomes.
　また、空気吹出口は空気吸込口より開口面積が大変小さいことから、空気吹出口及びこの空気吹出口の近傍に設けられた脱臭部を流れる空気の流速は、空気吸込口付近を流れる空気の流速に比べて速くなる。
　従って、このような構造では、脱臭部を流れる室内空気に含まれた臭気を吸着材が十分に吸着しきれない状態で、空気清浄機から室内へと空気が排出されることになり、人が室内空気の臭気が減少したと感じることができるまで、長い時間の間、空気清浄機を運転する必要がある。 In addition, since the air outlet has a much smaller opening area than the air inlet, the flow velocity of the air flowing through the air outlet and the deodorizing part provided in the vicinity of the air outlet is the flow velocity of the air flowing in the vicinity of the air inlet. Compared to
Therefore, in such a structure, air is discharged from the air cleaner into the room in a state where the adsorbent cannot sufficiently absorb the odor contained in the room air flowing through the deodorizing unit, It is necessary to operate the air purifier for a long time until it can be felt that the odor of room air has decreased.
　更に、吸着材を加熱することにより吸着材に吸着された臭気を除去する加熱部であるヒーターは、吸着材に対して固定して設けられているので、ヒーターと吸着材の距離が、近接した部分と離れた部分が形成される。
　これにより、ヒーターに近い吸着材の部位は、効率よく加熱することがでるので臭気を除去できるが、ヒーターから離れた吸着材の部位は、ヒーターからの熱が効率よく伝わらない恐れがあり、確実に臭気を除去しきれない可能性がある。
　従って、このような構成では、吸着材の臭気を吸着する能力を十分に回復させることができないことから、空気清浄機の脱臭機能の低下を招く恐れがある。 Furthermore, since the heater, which is a heating unit that removes the odor adsorbed by the adsorbent by heating the adsorbent, is provided fixed to the adsorbent, the distance between the heater and the adsorbent is close. A part away from the part is formed.
As a result, the adsorbent part close to the heater can be heated efficiently, so the odor can be removed. However, the adsorbent part away from the heater may not be able to transfer the heat efficiently. There is a possibility that the odor cannot be completely removed.
Accordingly, with such a configuration, the ability of adsorbing material to adsorb odors cannot be sufficiently recovered, and there is a risk of degrading the deodorizing function of the air cleaner.
　また、本体を移動して使いたいときに、上記のように各部が本体内部に設けられているので、本体が重く移動しにくい。例えば、ハンドルとキャスターにて移動可能にしても、本体上面にある吹出口からの風の流れをハンドルが阻害したり、ハンドルの位置が本体の重心からずれたりして、運びにくい場合がある。
　また、ハンドルを持ちやすい高さに設定しても、平均身長よりも低い人には、持ちにくくなってしまう心配がある。 Further, when it is desired to move and use the main body, since the respective parts are provided inside the main body as described above, the main body is heavy and difficult to move. For example, even if the handle and the caster are movable, the handle may hinder the flow of air from the air outlet on the top surface of the main body or the position of the handle may deviate from the center of gravity of the main body, which may be difficult to carry.
Moreover, even if the handle is set to a height that is easy to hold, there is a concern that it may be difficult for a person who is lower than the average height to hold the handle.
　更に、脱臭部には、臭気を吸着する触媒を表面に塗布又は含浸させているので、移動などの振動で、触媒が脱臭部から剥れて本体内部に落ちてしまう恐れがある。これにより、剥がれ落ちた触媒が、吹出口から放出してしまう恐れがある。 Furthermore, since the catalyst for adsorbing odor is applied or impregnated on the surface of the deodorizing portion, the catalyst may peel off from the deodorizing portion and fall into the main body due to vibrations such as movement. Thereby, there exists a possibility that the catalyst which peeled off may discharge | release from a blower outlet.
　更に、脱臭エレメントより上流側に配置した、塵埃濾過フィルターを着脱可能にするために、本体ケース前方に枠体を配置するが、本体の寸法のばらつきにより、移動など際の振動でガタツいたり、外れたりする恐れがある。 In addition, a frame is placed in front of the main body case in order to make it possible to attach and detach the dust filtration filter placed upstream from the deodorizing element. There is a risk that.
　更に、運転時に転倒し危険な状態にならないために、本体内部に転倒を検知する振動センサーを設ける場合、通常時の微弱振動を検知してしまう恐れがある。 Furthermore, when a vibration sensor for detecting a fall is provided inside the main body, there is a risk of detecting a weak vibration during normal operation so that it does not fall into danger during operation.
　更に、本体をキャスターで移動中に、プラグコードを踏んでしまい、それが原因で転倒する恐れがある。 Furthermore, while moving the main body with a caster, there is a risk of stepping on the plug cord and causing it to fall down.
　本発明は、上記のような問題点を解決するためになされたものであり、室内空気の臭気を効率よく減少させることができ、また、臭気を吸着する吸着材の機能を効率よく回復させることが可能であり、移動させやすい空気清浄機を提供することを目的とする。 The present invention has been made to solve the above-described problems, and can effectively reduce the odor of indoor air and efficiently restore the function of the adsorbent that adsorbs the odor. It is an object to provide an air purifier that can be easily moved.
　上記の課題を解決する為に、空気清浄機を、外部に向けて開口する吸込口及び吹出口が形成され、該吸込口と該吹出口を連通する通風を有する本体と、本体に内蔵され、吸込口から吹出口に至る通風路に室内空気を導入する送風手段と、通風路に設けられ、導入された空気が通過可能な脱臭エレメントと、脱臭エレメントを局部的に加熱する加熱ユニットと、この加熱ユニットと脱臭エレメントの相対的位置関係を変更する位置変更手段と、送風手段と加熱手段と位置変更手段の通電を制御する制御手段とを備え、脱臭エレメントは、加熱ユニットによって加熱されることで脱臭機能が回復するように構成し、本体ケースの底部には、複数個の車輪を有し、本体ケースの上部には、棒状の握り部を有するハンドルを備え、ハンドルの握り部は、本体ケースの左右方向に長く形成され、車輪は、少なくとも握り部の長手方向に回転自在に構成した。 In order to solve the above problems, a suction port and an air outlet that open the air cleaner toward the outside are formed, a main body having ventilation that communicates the suction port and the air outlet, and built in the main body. Blower means for introducing room air into the ventilation path from the inlet to the outlet, a deodorizing element provided in the ventilation path through which the introduced air can pass, a heating unit for locally heating the deodorizing element, A position changing means for changing the relative positional relationship between the heating unit and the deodorizing element, and a control means for controlling energization of the air blowing means, the heating means and the position changing means, and the deodorizing element is heated by the heating unit. It is configured to recover the deodorizing function, the bottom of the main body case has a plurality of wheels, and the upper part of the main body case is provided with a handle having a rod-like grip, and the handle grip Formed to extend in the lateral direction of the body case, the wheel is configured to be rotatable at least in the longitudinal direction of the grip portion.
　本発明によれば、より多くの室内空気を取り込み、室内空気の臭気を効率よく減少させることができると共に、移動しやすい空気清浄機を提供することが可能となる。 According to the present invention, it is possible to provide an air cleaner that can take in more room air, reduce the odor of room air efficiently, and is easy to move.

　尚、ガイド部６５ｅは、円形状の開口６５ａの円形の開口縁の外側に位置している。つまり、開口６５ａの縁とガイド部６５ｅの間には、隙間ｒが形成される。また、ガイド部６５ｅが形成するリングの直径は、後述する各部が設けられた脱臭エレメント６２を内部に保持可能な程度の大きさである。 In addition, the guide part 65e is located outside the circular opening edge of the circular opening 65a. That is, a gap r is formed between the edge of the opening 65a and the guide portion 65e. The diameter of the ring formed by the guide portion 65e is large enough to hold the deodorizing element 62 provided with each portion described later.
　そして、中仕切板６５の開口６５ａの中央支持体６５ｂの下方の領域であって、中央支持体６５ｂを中心に、左右に等しく広がる所定の開角により形成される扇形の領域は、扇形状の蓋体６５ｄにより覆われている。
　尚、この蓋体６５ｄはステンレスにより形成されており、中仕切板６５の後面側（裏面側）から、梁部６５ｃにネジなどにより固定される。 A sector-shaped region formed by a predetermined opening angle that extends equally to the left and right around the central support 65b is a region below the central support 65b of the opening 65a of the partition plate 65. It is covered with a lid 65d.
The lid body 65d is made of stainless steel, and is fixed to the beam portion 65c with screws or the like from the rear surface side (back surface side) of the intermediate partition plate 65.
　また、蓋体６５ｄは、後述する加熱ユニット６３と対向して位置するように配置され、加熱ユニット６３のヒーターユニット６３ａと対向した状態において、ヒーターユニット６３ａを覆うことが可能な大きさとなっている。つまり、加熱ユニット６３と蓋体６５ｄとが対向することで、後述する脱臭エレメント６２の加熱空間を形成している。
　尚、蓋体６５ｄには、熱放射率を向上させるための黒色の耐熱塗装が施されている。 The lid 65d is disposed so as to face a heating unit 63, which will be described later, and is large enough to cover the heater unit 63a in a state facing the heater unit 63a of the heating unit 63. . That is, the heating unit 63 and the lid 65d face each other to form a heating space for the deodorizing element 62 described later.
The lid 65d is provided with a black heat-resistant coating for improving the thermal emissivity.
　次に、脱臭エレメント６２は、平面形状が円板形状であり、セラミック又はアルミニウムにより形成された蜂の巣の開口のように複数の開口が形成されたハニカムコアに、バインダーで触媒が塗布又は含浸されたものである。
　尚、この触媒は、白金系やマンガンを用いたものなど、臭気（特に、アンモニア臭）を吸着する性質を有する触媒を用いる。また、触媒は、移動や運転時などの振動で、ハニカムコアから剥がれ落ちないように、剥がれ防止のコーティング処理が施されている。 Next, in the deodorizing element 62, the planar shape is a disk shape, and a catalyst is coated or impregnated with a binder on a honeycomb core formed with a plurality of openings such as honeycomb openings made of ceramic or aluminum. Is.
In addition, this catalyst uses the catalyst which has the property to adsorb | suck an odor (especially ammonia odor), such as what used platinum system and manganese. In addition, the catalyst is subjected to a coating treatment for preventing peeling so that the catalyst does not peel off from the honeycomb core due to vibration during movement or operation.
　また、脱臭エレメント６２の中心部には開口部６２ｃが形成され、前面には、脱臭エレメント６２を保持するステンレスにより形成されたエレメントフレーム６２ａが設けられている。
　ここで、上記のように脱臭エレメント６２は、ハニカムコアにより形成され、前面に設けられたエレメントフレーム６２ａには所定の開口が形成されている。このため、空気は脱臭エレメント６２の内部を前後方向に貫いて流れることができる。 An opening 62c is formed at the center of the deodorizing element 62, and an element frame 62a formed of stainless steel for holding the deodorizing element 62 is provided on the front surface.
Here, as described above, the deodorizing element 62 is formed of a honeycomb core, and a predetermined opening is formed in the element frame 62a provided on the front surface. For this reason, air can flow through the inside of the deodorizing element 62 in the front-rear direction.
　更に、脱臭エレメント６２の周縁には、脱臭エレメント６２を囲むように、ギア部６２ｂが設けられている。
　このギア部６２ｂを含む脱臭エレメント６２の直径は、中仕切板６５に形成された円形状の開口６５ａの直径より大きくなるように構成されている。 Further, a gear portion 62 b is provided on the periphery of the deodorizing element 62 so as to surround the deodorizing element 62.
The diameter of the deodorizing element 62 including the gear portion 62 b is configured to be larger than the diameter of the circular opening 65 a formed in the intermediate partition plate 65.
　次に、図９～図１０を参照すると、加熱ユニット６３は、脱臭エレメント６２を加熱する加熱手段であるヒーターユニット６３ａと、このヒーターユニット６３ａを内部に収納する所定の内部空間を有するケース６３ｂから構成されている。
　このヒーターユニット６３ａは、制御部４７に電気的に接続されており、空気清浄機Ａの状態に応じて通電制御されるものである。 Next, referring to FIGS. 9 to 10, the heating unit 63 includes a heater unit 63a that is a heating means for heating the deodorizing element 62, and a case 63b having a predetermined internal space in which the heater unit 63a is housed. It is configured.
The heater unit 63a is electrically connected to the controller 47 and is energized and controlled according to the state of the air purifier A.
　また、ヒーターユニット６３ａは、板状の発熱部６３ｆと、この発熱部６３ｆを熱するヒーター部６３ｇから構成されている。更に、発熱部６３ｆの平面形状は扇形状を成しており、表面にはヒーター部６３ｆから受けた熱の放射率を向上させるための耐熱塗装（黒色）が施されている。
　つまり、ヒーターユニット６３ａは、ヒーター部６３ｇで生じた熱を板状の発熱部６３ｆが受け、板面全体から熱を放射することにより、対向する脱臭エレメント６２をムラが少なく加熱する。
　そして、ヒーターユニット６３ａは所定の時間通電された場合、ヒーターユニット６３ａから所定の隙間を介在して配置された脱臭エレメント６２に対向した部位を、脱臭エレメント６２に吸着した臭気を除去可能な所定の温度まで上昇させることができる加熱能力に設定してある。 The heater unit 63a includes a plate-like heat generating portion 63f and a heater portion 63g that heats the heat generating portion 63f. Furthermore, the planar shape of the heat generating portion 63f is a fan shape, and heat-resistant coating (black) for improving the emissivity of heat received from the heater portion 63f is applied to the surface.
That is, the heater unit 63a receives the heat generated by the heater part 63g by the plate-like heat generating part 63f and radiates the heat from the entire plate surface, thereby heating the opposing deodorizing element 62 with little unevenness.
When the heater unit 63a is energized for a predetermined period of time, a portion facing the deodorizing element 62 disposed with a predetermined gap from the heater unit 63a is removed from the predetermined deodorizing element 62. It is set to a heating capacity that can be raised to a temperature.
　尚、ヒーター６３ｇは、チタン酸バリウムを主成分とする半導体セラミックであるＰＴＣヒーターを用いている。
　このＰＴＣヒーターは、自己温度制御性があり、外部からの温度制御を必要としないことから、サーモスタットのように断続的制御を行わないので、火花やノイズが発生せず、安定して使用することができる。 The heater 63g is a PTC heater that is a semiconductor ceramic mainly composed of barium titanate.
Since this PTC heater has self-temperature control and does not require external temperature control, it does not perform intermittent control like a thermostat, so it does not generate sparks or noise and should be used stably. Can do.
　次に、ケース６３ｂは、ヒーターユニット６３ａを内部に保持する凹部６３ｃと、この凹部６３ｃの開口周縁から広がるフランジ部６３ｄが形成されている。
　凹部６３ｃは、ヒーターユニット６３ａの平面形状と一致した扇形状を成しており、内部にヒーターユニット６３ａを凹部６３ｃの開口に臨ませた状態でヒーターユニット６３ａが設けられている。フランジ部６３ｄには、加熱ユニット６３を所定の位置に取り付ける際に螺子を貫通させるための螺子穴６３ｅが形成されている。
　以上のように構成される加熱ユニット６３は、平面形状がヒーターユニット６３ａの発熱部の形状に合わせて、扇形状に構成されており、凹部６３ｃの開口も扇形状に構成されている。 Next, the case 63b is formed with a concave portion 63c that holds the heater unit 63a inside, and a flange portion 63d that spreads from the opening periphery of the concave portion 63c.
The recess 63c has a fan shape that matches the planar shape of the heater unit 63a, and the heater unit 63a is provided with the heater unit 63a facing the opening of the recess 63c. The flange portion 63d is formed with a screw hole 63e for allowing the screw to pass therethrough when the heating unit 63 is attached to a predetermined position.
The heating unit 63 configured as described above is configured in a fan shape in accordance with the shape of the heat generating portion of the heater unit 63a, and the opening of the recess 63c is also configured in a fan shape.
　次に、図７を参照すると、駆動手段６４は、脱臭エレメント６２を動かして加熱ユニット６３と脱臭エレメントの対向する部位の相対的位置関係を変更する、つまり、加熱ユニット６３と対向する脱臭エレメント６２の部位を変更する位置変更手段である。
　駆動手段６４は、モーター６４ａと、このモーター６４ａを保持するブラケット６４ｂからなる。モーター６４ａの回転軸には、ギアが取付けられている。また、モーター６４ａは、制御部４７に電気的に接続されており、空気清浄機Ａの状態に応じて通電制御されるものである。 Next, referring to FIG. 7, the driving means 64 moves the deodorizing element 62 to change the relative positional relationship between the heating unit 63 and the opposite portion of the deodorizing element, that is, the deodorizing element 62 facing the heating unit 63. This is a position changing means for changing the part.
The driving means 64 includes a motor 64a and a bracket 64b that holds the motor 64a. A gear is attached to the rotation shaft of the motor 64a. The motor 64a is electrically connected to the control unit 47 and is energized and controlled according to the state of the air cleaner A.
　図４及び図７～図８を参照すると、以上の脱臭エレメント６２と加熱ユニット６３と駆動手段６４は、次のように枠体６１に取付けられることにより、脱臭部６０を構成する。尚、図７は、各部をわかりやすく表示するために、枠６５ｈを外した状態で示してある。
　まず、枠体６１の裏面より、中央支持体６５ｂに設けられた軸６５ｊに、脱臭エレメント６２の開口部６２ｃが軸受となって回転自在に嵌り込む。 Referring to FIG. 4 and FIGS. 7 to 8, the deodorizing element 62, the heating unit 63, and the driving means 64 described above constitute the deodorizing unit 60 by being attached to the frame body 61 as follows. FIG. 7 shows a state in which the frame 65h is removed in order to display each part in an easy-to-understand manner.
First, from the back surface of the frame body 61, the opening 62c of the deodorizing element 62 is rotatably fitted into a shaft 65j provided on the center support body 65b.
　これにより、脱臭エレメント６２は、枠体６１の裏面（後面）に形成されているガイド部６５ｅの内部に、脱臭エレメント６２が開口６５ａに臨んだ状態（対面した状態）で、枠体６１に対して回転自在に配置される。
　そして、この状態において、ガイド部６５ｅの縁に、開口６５ａの内方に突出するように、脱臭エレメント６２を受ける受部６５ｆが、脱臭エレメント６２の回転方向の動きを大きく阻害しない程度に、脱臭エレメント６２の後方（裏面）より保持する。 Thereby, the deodorizing element 62 is in the state where the deodorizing element 62 faces the opening 65a (facing the face) inside the guide portion 65e formed on the back surface (rear surface) of the frame body 61. And can be rotated freely.
In this state, the deodorizing element 65f that receives the deodorizing element 62 so as to protrude inward of the opening 65a at the edge of the guide part 65e does not greatly detract from the rotational movement of the deodorizing element 62. The element 62 is held from the rear (back surface).
　このように、脱臭エレメント６２が枠体６１に取付けられることで、脱臭エレメント６２は、中仕切板６５の開口６５ａに臨んだ状態で、中仕切板６５の裏面（隙間ｒ）と、ガイド部６５ｅと、受部６５ｆに囲まれた空間の内部に回転自在に保持される。
　尚、中央支持体６５ｂに設けた軸６５ｊと脱臭エレメント６２の開口部６２ａを、上記のように軸と軸受の関係となるように構成しなくても、脱臭エレメント６２をガイド部６５ｅにより保持する構造でもよい。 As described above, the deodorizing element 62 is attached to the frame body 61, so that the deodorizing element 62 faces the opening 65a of the intermediate partition plate 65, and the back surface (gap r) of the intermediate partition plate 65 and the guide portion 65e. And is rotatably held in the space surrounded by the receiving portion 65f.
The deodorizing element 62 is held by the guide portion 65e even if the shaft 65j provided in the central support 65b and the opening 62a of the deodorizing element 62 are not configured to have a relationship between the shaft and the bearing as described above. It may be a structure.
　次に、上記のように枠体６１に脱臭エレメント６２が配置された状態で、脱臭エレメント６２の一部を覆うように、枠体６１に加熱ユニット６３が次のように取付けられる。
　まず、加熱ユニット６３は、脱臭エレメント６２の中心から下側の部位を跨いで脱臭エレメント６２の回転を妨げないように配置される。
　この状態において、加熱ユニット６３のヒーターユニット６３ａが脱臭エレメント６２に直接近接して対向するように、ヒーターユニット６３ａが設けられた凹部６３ｃの開口が前方を向いている。 Next, in the state where the deodorizing element 62 is arranged on the frame body 61 as described above, the heating unit 63 is attached to the frame body 61 so as to cover a part of the deodorizing element 62 as follows.
First, the heating unit 63 is disposed so as not to hinder the rotation of the deodorizing element 62 across the lower part from the center of the deodorizing element 62.
In this state, the opening of the recess 63c provided with the heater unit 63a faces forward so that the heater unit 63a of the heating unit 63 faces the deodorizing element 62 in direct proximity.
　そして、加熱ユニット６３は、脱臭エレメント６２の開口部６２ｃに位置する中央支持体６５ｂと、脱臭エレメント６２の外側に位置する中仕切板６５に形成された取付け位置に螺子止めされる。
　尚、この状態において、加熱ユニット６３と蓋体６５ｄは、脱臭エレメント６２を介して向かい合う位置関係となっている。 The heating unit 63 is screwed to a mounting position formed on the central support 65 b located in the opening 62 c of the deodorizing element 62 and the intermediate partition plate 65 located outside the deodorizing element 62.
In this state, the heating unit 63 and the lid 65d are in a positional relationship facing each other through the deodorizing element 62.
　以上のように構成することにより、加熱ユニット６３は、脱臭エレメント６２の回転方向の動きを阻害することなく、枠体６１に固定される。
　また、加熱ユニット６３と蓋体６５ｄが向かい合って枠体６１に配置されるので、加熱ユニット６３と蓋体６５ｄの間に脱臭エレメント６２を介在させた状態で、ヒーターユニット６３ａの熱を留める空間が形成される。更に、発熱部６３ｆは、熱の放射率を向上させる塗装が施されているので、ヒーター部６３ｇから受けた熱を効率よく放射する。
　これにより、加熱ユニット６３は、対向する脱臭エレメント６２の部位を局所的に効率よく加熱することができるように構成されている。 By configuring as described above, the heating unit 63 is fixed to the frame body 61 without hindering the movement of the deodorizing element 62 in the rotational direction.
Further, since the heating unit 63 and the lid body 65d face each other and are disposed on the frame body 61, there is a space for holding the heat of the heater unit 63a with the deodorizing element 62 interposed between the heating unit 63 and the lid body 65d. It is formed. Furthermore, since the heat generating portion 63f is coated to improve the heat emissivity, it efficiently radiates the heat received from the heater portion 63g.
Thereby, the heating unit 63 is comprised so that the site | part of the deodorizing element 62 which opposes can be heated locally efficiently.
　次に、駆動手段６４は、モーター６４ａがブラケットに６４ｂに保持された状態で、ブラケット６４ｂが中仕切板６５に固定される。この時、モーター６４ａの回転軸に取付けられたギアは、脱臭エレメント６２に設けられたギア６２ｂと歯合している。
　また、駆動手段６４の配置位置は、中仕切板６５の裏面であって、開口６５ａと中仕切板６５の角６５ｇに挟まれた部位である。更に、この駆動手段６４を設ける部位は、４つある角６５ｇの内、加熱ユニット６３から離れた上方に位置する角６５ｇと開口６５ａにより挟まれた部位であるとよい。 Next, in the driving means 64, the bracket 64 b is fixed to the middle partition plate 65 in a state where the motor 64 a is held by the bracket 64 b. At this time, the gear attached to the rotating shaft of the motor 64 a meshes with the gear 62 b provided on the deodorizing element 62.
In addition, the arrangement position of the driving means 64 is the rear surface of the middle partition plate 65 and the portion sandwiched between the opening 65 a and the corner 65 g of the middle partition plate 65. Further, the part where the driving means 64 is provided may be a part sandwiched by the opening 65a and the corner 65g located above the heating unit 63 among the four corners 65g.
　このように駆動手段６４を設けることにより、制御部４７による通電制御でモーター６４ａが駆動されることで、枠体６１に対して脱臭エレメント６２を回転させることが可能となり、脱臭エレメント６２の加熱ユニット６３と対向する部位を変更可能となる。
　つまり、加熱ユニット６３と脱臭エレメント６２の相対的位置関係を変更可能とすることができる。
　また、開口６５ａと角６５ｇに挟まれた位置に駆動部６４を設けたので、長方形の中仕切板６５に形成された開口６５ａの周囲のデッドスペースを有効に利用できる。更に、加熱ユニット６３から離れた位置に駆動手段６４を設けたので、加熱ユニット６３から生じる熱の影響を駆動部６４が受けにくい構造とすることができる。 By providing the driving means 64 in this way, the motor 64a is driven by the energization control by the control unit 47, whereby the deodorizing element 62 can be rotated with respect to the frame body 61, and the heating unit of the deodorizing element 62 is obtained. The part facing 63 can be changed.
That is, the relative positional relationship between the heating unit 63 and the deodorizing element 62 can be changed.
Further, since the drive unit 64 is provided at a position sandwiched between the opening 65a and the corner 65g, the dead space around the opening 65a formed in the rectangular partition plate 65 can be used effectively. Furthermore, since the drive means 64 is provided at a position away from the heating unit 63, the drive unit 64 can be made less susceptible to the influence of heat generated from the heating unit 63.
　次に、以上のように各部が構成された前パネル１０と前ケース２０と後ケース４０と脱臭部６０は、次のように他の機能部品と共に組み立てられることで、空気清浄機Ａを構成する。
　まず、後ケース４０は開口４１を前方に向けて、前ケース２０の後面に取付けられる。この時、後ケース４０に設けられた送風ファン４４の開口４４ｄは、前ケース２０に設けられた仕切板２３に形成された後開口２４と、対向した位置関係となっている。 Next, the front panel 10, the front case 20, the rear case 40, and the deodorizing unit 60, each part of which is configured as described above, are assembled together with other functional parts as follows to configure the air purifier A. .
First, the rear case 40 is attached to the rear surface of the front case 20 with the opening 41 facing forward. At this time, the opening 44 d of the blower fan 44 provided in the rear case 40 is in a positional relationship opposite to the rear opening 24 formed in the partition plate 23 provided in the front case 20.
　次に、脱臭部６０は、枠体６１が前ケース２０の前開口２２から前ケース２０の内部に挿入されて、枠体６１の外周が前ケース２０の内部に保持されることにより、前ケース２０に取付けられる。
　このように脱臭部６０が前ケース２０に取付けられた状態において、脱臭部６０の後面側（加熱ユニット６３が取付けられている位置側）が、前ケース２０の後開口２４を向くように配置され、脱臭エレメント６２と後開口２４の間に、加熱ユニット６３が位置することになる。 Next, the deodorizing unit 60 is configured such that the frame 61 is inserted into the front case 20 from the front opening 22 of the front case 20 and the outer periphery of the frame 61 is held inside the front case 20. 20 is attached.
In this state where the deodorizing part 60 is attached to the front case 20, the rear side of the deodorizing part 60 (position side where the heating unit 63 is attached) is arranged to face the rear opening 24 of the front case 20. The heating unit 63 is positioned between the deodorizing element 62 and the rear opening 24.
　ここで、脱臭エレメント６２と、送風ファン４４の開口４４ｄの周囲にベルマウスを形成する前ケース２０の仕切板２３及び後開口２４は、脱臭エレメント６２から後開口２４への空気の流れを妨げない為に、所定の間隔Ｄを空けて対向している（図４参照）。
　加熱ユニット６３は、このようにして形成された間隔Ｄの部位に位置している。 Here, the deodorizing element 62 and the partition plate 23 and the rear opening 24 of the front case 20 that form a bell mouth around the opening 44 d of the blower fan 44 do not hinder the flow of air from the deodorizing element 62 to the rear opening 24. Therefore, they face each other with a predetermined distance D (see FIG. 4).
The heating unit 63 is located at the part of the interval D formed in this way.
　次に、前ケース２０に取付けられた脱臭部６０の枠体６１の内方には、枠体６１の開口と同程度の大きさであるＨＥＰＡフィルター１２が設けられ、このＨＥＰＡフィルター１２の前面を覆うようにプレフィルター１３が設けられる。
　そして、プレフィルター１３の前面側に、前ケース２０の上突出部２８と下突出部２５に挟まれて、前パネル１０が設けられることで、空気清浄機Ａが構成される。 Next, a HEPA filter 12 having the same size as the opening of the frame body 61 is provided inside the frame body 61 of the deodorizing unit 60 attached to the front case 20. A prefilter 13 is provided so as to cover it.
And the air cleaner A is comprised by the front panel 10 being provided in the front side of the pre filter 13 between the upper protrusion part 28 and the lower protrusion part 25 of the front case 20.
　ここで、図１８を参照して、前パネル１０の前ケース２０への取付け構造について説明する。
　前パネル１０は蓋形状を成しており、上辺より下方に向けて突出する引っ掛け部１０ａと、左右の辺の内方に設けられたラッチ１０ｂと、このラッチ１０ｂの近傍に後述する前パネル押え部２５ｂが当接する当接部１０ｃを有する。 Here, with reference to FIG. 18, the attachment structure to the front case 20 of the front panel 10 is demonstrated.
The front panel 10 has a lid shape, a hooking portion 10a that protrudes downward from the upper side, a latch 10b provided inward of the left and right sides, and a front panel presser that will be described later in the vicinity of the latch 10b. It has the contact part 10c with which the part 25b contacts.
　また、前ケース２０には、上突出部２８の上面には凹部２８ａが形成され、左右の辺の下側にはラッチ受部２５ａが設けられ、ラッチ受部２５ａの近傍には前パネル押え部２５ｂが設けられている。
　この前パネル押え部２５ｂは、内部にバネやゴムなどの弾性部材を有するバネ機構であり、前ケース２０の前方に向けて付勢した状態となっている。尚、本実施の形態ではバネを用いたもので説明する。 Further, the front case 20 is formed with a recess 28a on the upper surface of the upper protruding portion 28, a latch receiving portion 25a is provided below the left and right sides, and a front panel pressing portion is provided in the vicinity of the latch receiving portion 25a. 25b is provided.
The front panel pressing portion 25b is a spring mechanism having an elastic member such as a spring or rubber inside, and is biased toward the front of the front case 20. In the present embodiment, description will be made using a spring.
　この様に構成された前パネル１０は、次のように前ケース２０の前面に取付けられる。まず、凹部２８ａに引っ掛け部１０ａが入り込み、ラッチ２５ａにラッチ受部１０ｂが係合することにより、前パネル１０は前ケース２０に固定される。
　この時、前パネル１０の当接部１０ｃには、所定の量バネを縮めた状態で、前パネル押え部２５ｂが当接した状態となる。このように、前パネル押え部２５ｂが所定の量バネを縮めて前パネル１０に当接することにより、前パネル１０は前方に押圧されて前ケース２０に保持される。
　これにより、前パネル１０と前ケース２０との間に、寸法のばらつきにより生ずるガタツキがあっても、移動の振動などで大きくガタツたり、両部材の係合が外れたりすることを防止できる。 The front panel 10 configured in this manner is attached to the front surface of the front case 20 as follows. First, the front panel 10 is fixed to the front case 20 by the hook portion 10a entering the recess 28a and the latch receiving portion 10b engaging the latch 25a.
At this time, the front panel pressing portion 25b is in contact with the contact portion 10c of the front panel 10 in a state where the spring is contracted by a predetermined amount. Thus, the front panel pressing portion 25b contracts the spring by a predetermined amount and contacts the front panel 10, whereby the front panel 10 is pressed forward and held by the front case 20.
Thereby, even if there is a backlash caused by the dimensional variation between the front panel 10 and the front case 20, it is possible to prevent the backlash from being greatly fluctuated due to vibration of movement or the like, and the disengagement of both members.
　尚、ＨＥＰＡフィルター１２とは、空気中に含まれる花粉、ダニの糞、カビの胞子、ハウスダストなどの微細な塵埃を取り除くためのフィルターである。
　また、プレフィルター１３とは、ＨＥＰＡフィルターで空気をろ過する前に、あらかじめ空気に含まれる大きな塵埃を取り除くための目の粗いフィルターであり、ＨＥＰＡフィルターの効果を長期間保つ為のものである。 The HEPA filter 12 is a filter for removing fine dust such as pollen, mite feces, mold spores and house dust contained in the air.
The prefilter 13 is a coarse filter for removing large dust contained in the air in advance before filtering the air with the HEPA filter, and is for maintaining the effect of the HEPA filter for a long period of time.
　次に、図４を参照すると、以上のように構成された空気清浄機Ａの内部には、室内空気を取り込み、この空気の清浄および脱臭を行い、室内へ放出する通風路Ｒが形成される。この風路Ｒについて、空気清浄機Ａの空気清浄運転状態と、内部に取り込まれた空気の流れに沿って説明する。
　まず、使用者が操作部２６を操作することで、制御部４７に対して入力を行うことにより、空気清浄機Ａの運転を行う所定のプログラムが実行される。 Next, referring to FIG. 4, an air passage R is formed in the air cleaner A configured as described above, which takes in indoor air, cleans and deodorizes the air, and discharges the air into the room. . The air path R will be described along the air purifying operation state of the air purifier A and the flow of air taken into the inside.
First, a predetermined program for operating the air purifier A is executed when the user operates the operation unit 26 to input to the control unit 47.
　上記の運転開始後、送風ファン４４が駆動されると、空気吸込口１１から空気清浄機Ａの内部に室内空気を取り込む吸込み力が生じ、室内空気が空気吸込口１１へ流入する。
　空気吸込口１１から取り込まれた空気は、空気清浄機Ａの内部を後方へと流れ、プレフィルター１３で大きな塵埃が取り除かれた後、ＨＥＰＡフィルター１２で微細な塵埃が取り除かれる。 When the blower fan 44 is driven after the start of the operation, a suction force for taking in room air from the air suction port 11 into the air cleaner A is generated, and the room air flows into the air suction port 11.
The air taken in from the air suction port 11 flows backward in the air purifier A, and after removing large dust with the pre-filter 13, fine dust is removed with the HEPA filter 12.
　次に、塵埃が取り除かれた空気は、更に後方へと流れて脱臭部６０へ到達し、開口６５ａを通過して、この開口部６５ａに臨む位置に配置された脱臭エレメント６２に至る。この脱臭エレメント６２は、表面から裏面に至るハニカム形状の多数の開口が形成されており、表面に臭気を吸着する触媒が塗布されている。 Next, the air from which the dust has been removed flows further rearward and reaches the deodorizing unit 60, passes through the opening 65a, and reaches the deodorizing element 62 disposed at a position facing the opening 65a. The deodorizing element 62 has a large number of honeycomb-shaped openings extending from the front surface to the back surface, and a catalyst for adsorbing odor is applied to the surface.
　従って、臭気を含んだ空気が、脱臭エレメント６２の表側から裏側へと通過する際に、ハニカム形状の開口を通過し、脱臭エレメント６２に塗布された触媒が、空気に含まれる臭気を吸着することにより、空気から臭気が取り除かれる。
　尚、「空気から臭気が取り除かれる」とは、空気から完全に臭気が無くなる状態のみならず、空気の脱臭エレメント６２を通過する前の状態から臭気が減少した状態も含む。
　ここで、上記のように空気清浄機Ａを運転し続けることにより、脱臭エレメント６２には、吸着した臭気が蓄積されていくことになり、吸着した臭気が増えるに従って、脱臭エレメント６２の脱臭能力が低下していく。 Therefore, when the odor-containing air passes from the front side to the back side of the deodorizing element 62, it passes through the honeycomb-shaped opening, and the catalyst applied to the deodorizing element 62 adsorbs the odor contained in the air. Odor is removed from the air.
Note that “the odor is removed from the air” includes not only a state in which the odor is completely removed from the air but also a state in which the odor is reduced from the state before the air passes through the deodorizing element 62.
Here, by continuing to operate the air purifier A as described above, the adsorbed odor is accumulated in the deodorizing element 62, and the deodorizing ability of the deodorizing element 62 increases as the adsorbed odor increases. It goes down.
　次に、塵埃と臭気が取り除かれた空気は、脱臭エレメント６２から更に後方に流れ、前ケース２０の仕切板２３に開口する後開口２４を通過して、この後開口２４に対向して配置されている送風ファン４４へと流れる。
　送風ファン４４へと流れる空気は、送風ファン４４の軸方向前方から周囲を羽４４ａに囲まれたファン開口４４ｄの内部へと流下し、送風ファン４４の上方を含む送風ファン４４の径方向へと送風ファン４４の外部に吐き出される。 Next, the air from which the dust and odor have been removed flows further rearward from the deodorizing element 62, passes through the rear opening 24 that opens in the partition plate 23 of the front case 20, and is disposed to face the rear opening 24. It flows to the blower fan 44.
The air flowing to the blower fan 44 flows from the front of the blower fan 44 in the axial direction to the inside of the fan opening 44d surrounded by the wings 44a, and into the radial direction of the blower fan 44 including the upper part of the blower fan 44. The air is discharged outside the blower fan 44.
　送風ファン４４から吐き出された空気は、後ケース４０に仕切板４５により導かれ、ルーバー４６を通過する際に風向が整えられ、空気吹出口４２から空気清浄機Ａの上方向に向けて、空気清浄機Ａの内部からの清浄空気として吹き出される。
　このように通風路Ｒは、空気吸込口１１から水平方向に空気清浄機本体の後部へと繋がり、この後部で上方へと向きを変えて空気吹出口４２へと至る風路である。 The air discharged from the blower fan 44 is guided to the rear case 40 by the partition plate 45, the air direction is adjusted when passing through the louver 46, and the air is directed from the air outlet 42 upward to the air cleaner A. It is blown out as clean air from the inside of the cleaner A.
Thus, the ventilation path R is an air path that connects from the air suction port 11 to the rear part of the air cleaner main body in the horizontal direction and changes the direction upward at this rear part to reach the air outlet 42.
　つまり、通風路Ｒは、空気の流れを基準に見ると、脱臭エレメント６２の上流側に、プレフィルター１３やＨＥＰＡフィルター１２などの塵埃濾過フィルターが配置され、脱臭エレメント６２の下流側で、空気の流れの向きを上方に屈曲して変える位置である屈曲部が形成されている。この屈曲部に送風ファン４４であるシロッコファンが位置している。
　このシロッコファンは、ファンの回転軸方向から空気を取り込み、ファンの径方向へと取り込んだ空気を吐き出すので、室内空気を本体ケースＣの前面から後方への直線的な流れを作り出すと共に、吹出口４２に向けて効率よく風の向きを変えることができる。 That is, in the ventilation path R, a dust filtering filter such as the prefilter 13 and the HEPA filter 12 is disposed on the upstream side of the deodorizing element 62 when viewed with reference to the air flow. A bent portion is formed, which is a position where the flow direction is bent upward and changed. The sirocco fan which is the ventilation fan 44 is located in this bending part.
Since this sirocco fan takes in air from the rotation axis direction of the fan and exhales air taken in the radial direction of the fan, the indoor air creates a linear flow from the front of the main body case C to the rear, The direction of the wind can be efficiently changed toward 42.
　尚、脱臭エレメント６２，プレフィルター１３，ＨＥＰＡフィルター１２，送風ファン４４の開口４４ｄの前面は、通風路Ｒを流れる空気の向きに対して、垂直な向きに配置されている。
　これにより、脱臭エレメントまで空気の流れがまっすぐで、各フィルター面に垂直に空気が当たるので空気の流れがよい構成となっている。 Note that the front surfaces of the opening 44d of the deodorizing element 62, the prefilter 13, the HEPA filter 12, and the blower fan 44 are arranged in a direction perpendicular to the direction of the air flowing through the ventilation path R.
Thereby, since the air flow is straight to the deodorizing element and the air hits each filter surface vertically, the air flow is good.
　ここで、開口６５ａの位置は、本体ケースＣの正面の上下方向の中央に位置し、本体ケースＣの正面視における投影面積Ｘと、開口６５ａの正面視における面積Ｙとの関係が、
　Ｙ≧０．６Ｘ
となるように構成されている。 Here, the position of the opening 65a is located at the center in the vertical direction of the front surface of the main body case C, and the relationship between the projected area X in the front view of the main body case C and the area Y in the front view of the opening 65a is
Y ≧ 0.6X
It is comprised so that it may become.
　次に、以上のように、空気清浄運転（脱臭運転）したことにより、多くの臭気を吸着して脱臭性能が低下した脱臭エレメント６２の脱臭性能を回復させるための動作（再生動作）について説明する。
　制御部４７は、所定のタイミング、例えば、運転開始又は前回行った脱臭エレメント６２の脱臭性能回復動作からの累積運転時間が所定の時間を超えた場合、次のように脱臭性能回復動作を行う。 Next, an operation (regeneration operation) for recovering the deodorizing performance of the deodorizing element 62 that has adsorbed a lot of odors and reduced the deodorizing performance due to the air cleaning operation (deodorizing operation) as described above will be described. .
When the accumulated operation time from the deodorizing performance recovery operation of the deodorizing element 62 that is started or last performed exceeds a predetermined time, the control unit 47 performs the deodorizing performance recovery operation as follows.
　送風ファン４４が停止している状態、つまり、空気清浄機Ａが空気清浄運転を終えた後、又は、空気清浄運転を行っていない状態において、制御部４７はヒーターユニット６３ａに対して通電を行うことで、ヒーターユニット６３ａを発熱させ、ヒーターユニット６３ａと対向している脱臭エレメント６２の部位を所定の温度まで上昇させて、所定の時間加熱する。
　この脱臭エレメント６２の加熱温度及び加熱時間は、脱臭エレメント６２に吸着した臭気を除去させるのに十分な温度と時間である。 In a state where the blower fan 44 is stopped, that is, after the air purifier A finishes the air cleaning operation or in a state where the air cleaning operation is not performed, the control unit 47 energizes the heater unit 63a. As a result, the heater unit 63a generates heat, the portion of the deodorizing element 62 facing the heater unit 63a is raised to a predetermined temperature, and heated for a predetermined time.
The heating temperature and heating time of the deodorizing element 62 are a temperature and time sufficient to remove the odor adsorbed on the deodorizing element 62.
　尚、脱臭エレメント６２の加熱される部位は、前面側が熱の放射率を向上させる塗装が施されている蓋体６３ｄに覆われ、後面側が加熱ユニット６３（ヒーターユニット６３ａ）に覆われるので、ヒーターユニット６３ａから生ずる熱と、蓋体６３ｄから放射される熱により、効率よく脱臭エレメント６２を加熱することができる。
　また、脱臭エレメント６２は、ヒーターユニット６３ａと蓋体６３ｄに挟まれて位置しているので、これら部材から放射される熱が、脱臭エレメント６２の近傍に留まりやすく、より効率よく脱臭エレメント６２を加熱することができる。 Note that the heated portion of the deodorizing element 62 is covered with a lid 63d that is coated with a coating that improves the heat emissivity and the rear surface is covered with the heating unit 63 (heater unit 63a). The deodorizing element 62 can be efficiently heated by the heat generated from the unit 63a and the heat radiated from the lid 63d.
Moreover, since the deodorizing element 62 is located between the heater unit 63a and the lid 63d, the heat radiated from these members easily stays in the vicinity of the deodorizing element 62, and heats the deodorizing element 62 more efficiently. can do.
　次に、上記のように、加熱ユニット６３と対向する部位の脱臭性能回復動作が終了すると、制御部４７は脱臭ユニット６２を回動させる駆動手段６４を動作させて、脱臭ユニット６２を所定の角度だけ回転させる。
　この動作により、加熱ユニット６３と対向していた脱臭エレメント６２の加熱処理が終了した部位が、加熱エレメント６３に対して回転方向にずれる。
　これにより、加熱処理が完了している脱臭ユニット６２の部位が、加熱ユニット６３と蓋体６３ｄに挟まれた位置から外れると共に、新たに臭気を多く吸着した脱臭エレメント６２の部位が、加熱ユニット６３と蓋体６３ｄに挟まれた部位に位置することとなる。 Next, as described above, when the deodorizing performance recovery operation for the portion facing the heating unit 63 is completed, the control unit 47 operates the driving means 64 that rotates the deodorizing unit 62 to move the deodorizing unit 62 to a predetermined angle. Just rotate.
By this operation, the portion where the heat treatment of the deodorizing element 62 facing the heating unit 63 is shifted in the rotation direction with respect to the heating element 63.
As a result, the part of the deodorizing unit 62 for which the heat treatment has been completed is removed from the position sandwiched between the heating unit 63 and the lid 63d, and the part of the deodorizing element 62 that has newly adsorbed a lot of odors is removed. And the lid 63d.
　尚、脱臭ユニット６２を回転させる角度は、扇形状であるヒーターユニット６３ａの開角と同じか、又は、この開角より小さい角度がよい。このように回転角度を設定することで、脱臭ユニット６２が１周回転する内に、脱臭ユニット６２のいずれの部位も、必ずヒーターユニット６３ａの前に留まり、加熱処理されることになる。
　また、脱臭ユニット６２を動かすタイミングは、加熱処理の後、直ぐに行ってもよく、また、次に行う空気清浄運転の直前に行ってもよい。 In addition, the angle which rotates the deodorizing unit 62 is the same as the opening angle of the fan-shaped heater unit 63a, or an angle smaller than this opening angle is good. By setting the rotation angle in this way, any part of the deodorizing unit 62 always stays in front of the heater unit 63a and is subjected to heat treatment while the deodorizing unit 62 rotates once.
Moreover, the timing which moves the deodorizing unit 62 may be performed immediately after a heat processing, and may be performed immediately before the air purifying operation performed next.
　次に、図１１～図１２を参照して、脱臭部６０について説明すると、脱臭部６０を構成する中仕切板６５の開口６５ａの内部中央に位置する中央支持体６５ｂの下方の領域であって、中央支持体６５ｂを中心に、左右に等しく広がる所定の開角により形成される扇形の領域は、中仕切板６５の裏側より略扇形状の蓋体６５ｄにより覆われている。 Next, the deodorizing unit 60 will be described with reference to FIGS. 11 to 12. The deodorizing unit 60 is a region below the central support 65b located in the center of the opening 65a of the middle partition plate 65 constituting the deodorizing unit 60. The fan-shaped region formed by a predetermined opening angle that extends equally to the left and right with the central support 65b as the center is covered by a substantially fan-shaped lid 65d from the back side of the middle partition plate 65.
　この蓋体６５ｄはステンレスにより形成されており、中仕切板６５の後面側（裏面側）から、梁部６５ｃにネジなどにより固定される。また、蓋体６５ｄは、後述する加熱ユニット６３のヒーターユニット６３ａと対向した状態において、ヒーターユニット６３ａを覆うことが可能な大きさとなっている。
　そして、この蓋体６５ｄが上記のように取付けられた状態において、蓋体６５ｄの前面と梁部６５ｃにより囲まれた部位には、断熱材６６が設けられる。更にこの断熱材６６の前側には、カバー６７が設けられる。カバー６７は、樹脂により形成されており、中仕切板６５の前面側（表面側）から、梁部６５ｃにネジなどにより固定される。 The lid body 65d is made of stainless steel, and is fixed to the beam portion 65c with screws or the like from the rear surface side (back surface side) of the intermediate partition plate 65. The lid 65d has a size that can cover the heater unit 63a in a state where the lid 65d faces a heater unit 63a of the heating unit 63 described later.
In the state where the lid body 65d is attached as described above, a heat insulating material 66 is provided in a portion surrounded by the front surface of the lid body 65d and the beam portion 65c. Further, a cover 67 is provided on the front side of the heat insulating material 66. The cover 67 is made of resin, and is fixed to the beam portion 65c with screws or the like from the front side (surface side) of the middle partition plate 65.
　以上のように各部を構成すれば、蓋体６５ｄの前面を断熱材６６で覆ってあるので、脱臭エレメント６２を加熱ユニット６３で加熱する際に、加熱ユニット６３と対向することで加熱空間を形成している蓋体６５ｄの表面から、この加熱空間の熱を逃げ難くすることができる。
　従って、加熱空間の温度を効率よく上げることができ、効率よく脱臭エレメント６２を加熱することが可能となると共に、高温になる蓋体６５ｄを使用者が直接触れることができないので、火傷を防止することができる。 If each part is configured as described above, since the front surface of the lid 65d is covered with the heat insulating material 66, a heating space is formed by facing the heating unit 63 when the deodorizing element 62 is heated by the heating unit 63. The heat of the heating space can be made difficult to escape from the surface of the lid body 65d.
Therefore, the temperature of the heating space can be increased efficiently, the deodorizing element 62 can be efficiently heated, and the user cannot directly touch the lid 65d that is at a high temperature, thus preventing burns. be able to.
　次に、図１３～図１４を参照して、吹出口４２について説明する。尚、図１３～図１４において、吹出口４２の開口部分には、通常は格子が取付けられているが、ルーバー４６の動きを説明するため、格子を取外した状態で示してある。
　まず、吹出口４２の近傍にルーバー４６は、複数の板状の風向板４６ａと、この複数の風向板４６ａをそれぞれ繋いで風向板４６ａを所定の角度に動かすリンク機構４６ｃと、このリンク機構４６ｃを動かす駆動部（図示せず）から構成されている。 Next, the air outlet 42 will be described with reference to FIGS. In FIGS. 13 to 14, a lattice is usually attached to the opening of the air outlet 42, but the lattice is removed in order to explain the movement of the louver 46.
First, the louver 46 in the vicinity of the air outlet 42 includes a plurality of plate-like wind direction plates 46a, a link mechanism 46c that connects the plurality of wind direction plates 46a to move the wind direction plate 46a to a predetermined angle, and the link mechanism 46c. It is comprised from the drive part (not shown) which moves.
　そして、ルーバー４６は、複数の板状の風向板４６ａが、吹出口４２の開口に所定の間隔を空けて、それぞれ平行となるように並んで配置されており、それぞれの風向板４６ａは、この風向板４６ａの両端に形成された軸で、吹出口４２に軸支されている。
　尚、リンク機構４６ｃを動かす駆動部は、後述する制御部４７に接続されており、空気清浄機の状態に応じて、所定のプログラムで駆動されるものであり、これにより、ルーバー４６の向きが変更される。 The louver 46 includes a plurality of plate-like wind direction plates 46a arranged in parallel so as to be parallel to each other at a predetermined interval from the opening of the air outlet 42. The shafts formed at both ends of the wind direction plate 46a are supported by the air outlet 42.
The drive unit that moves the link mechanism 46c is connected to a control unit 47, which will be described later, and is driven by a predetermined program in accordance with the state of the air purifier. Be changed.
　また、風向板４６ａの大きさは、前後方向の幅が吹出口４２の前後方向の幅と略一致すると共に、左右方向の最大幅は、ルーバー４６を閉じた状態、つまり、風向板４６ａが倒れた状態において、隣り合う風向板４６ａにより、吹出口４２をさえぎる程度の大きさに構成されている。 Further, the size of the wind direction plate 46a is such that the width in the front-rear direction substantially coincides with the width in the front-rear direction of the air outlet 42, and the maximum width in the left-right direction is the state where the louver 46 is closed, that is, the wind direction plate 46a collapses. In such a state, the adjacent wind direction plate 46a is configured to have a size enough to block the air outlet 42.
　そして、ルーバー４６は、脱臭エレメント６２を加熱処理する間、各々の風向板４６ａが吹出口４２をさえぎるように、倒れた状態となるように、制御部４７がリンク機構４６ｃを動かす駆動部を動作させる。
　このように、脱臭エレメント６２の加熱処理の間、ルーバー４６により吹出口４２を塞ぐことにより、加熱処理時に生じる脱臭エレメント６２からに臭いなどを空気清浄機Ａの外部に放出し難くすることができる。 The louver 46 operates a drive unit that causes the control unit 47 to move the link mechanism 46c so that each wind direction plate 46a blocks the air outlet 42 while the deodorizing element 62 is heated. Let
Thus, during the heat treatment of the deodorizing element 62, the blowout port 42 is blocked by the louver 46, so that it is difficult to release odors and the like from the deodorizing element 62 generated during the heat treatment to the outside of the air cleaner A. .
　尚、本実施の形態において、吹出口４２に設けられたルーバー４６により吹出口４２を塞ぐ構成を説明したが、ルーバー４６とは別に、吹出口４２を開閉するシャッターなどのようなものを設けてもよい。
　また、吹出口４２のみならず、吸込口１１にこの吸込口１１の開口を開閉するシャッターなどを設けて、脱臭エレメント６２の加熱処理時に吸込口１１を閉鎖することにより、更に、加熱処理時に生じる脱臭エレメント６２からに臭いなどを空気清浄機Ａの外部に放出し難くすることが可能となる。 In addition, in this Embodiment, the structure which block | closes the blower outlet 42 with the louver 46 provided in the blower outlet 42 was demonstrated, However, In addition to the louver 46, things, such as a shutter which opens and closes the blower outlet 42, are provided. Also good.
Further, not only the air outlet 42 but also the air inlet 11 is provided with a shutter that opens and closes the opening of the air inlet 11, and the air inlet 11 is closed during the heat treatment of the deodorizing element 62. It is possible to make it difficult to release odors and the like from the deodorizing element 62 to the outside of the air purifier A.
　以上のように空気清浄機Ａの内部の各部を構成することにより、次のような効果を得ることができる。
　本実施の形態のように、脱臭エレメント６２と、この脱臭エレメント６２を局部的に加熱する加熱ユニット６３との相対的位置関係を変更可能に構成することにより、加熱ユニット６３を小型化することができる。
　この加熱ユニット６３の小型化のメリットは、例えば、脱臭エレメント６２の全域を確実に加熱処理できるように、脱臭エレメント６２の全域に対面するような、大型のヒーターを配置する必要がなく、構造の簡略化やコスト低減を可能とする。 By configuring each part inside the air cleaner A as described above, the following effects can be obtained.
As in the present embodiment, the configuration of the deodorizing element 62 and the heating unit 63 that locally heats the deodorizing element 62 can be changed so that the heating unit 63 can be downsized. it can.
The advantage of downsizing the heating unit 63 is, for example, that there is no need to arrange a large heater that faces the entire area of the deodorizing element 62 so that the entire area of the deodorizing element 62 can be surely heated. Enables simplification and cost reduction.
　また、加熱ユニット６３と脱臭エレメント６２の相対的位置関係を変更可能であるので、脱臭エレメント６２の全域を脱臭するにあたり、脱臭エレメント６２と加熱ユニット６３の対向する部位を変更すればよく、加熱ユニット６３は脱臭エレメント６２の全域を覆う必要がない。
　つまり、常に脱臭エレメント６２が加熱ユニット６３と対向する部位は、限られた部分で済むことから、加熱ユニット６３が脱臭エレメント６２を流れる空気の流れの妨げを最小限ですむ。これにより、脱臭エレメント６２に対して、より多くの空気を流すことが可能であり、より多くの臭気を一度に空気中から取り除くことができる。 In addition, since the relative positional relationship between the heating unit 63 and the deodorizing element 62 can be changed, in order to deodorize the entire area of the deodorizing element 62, the opposing portion of the deodorizing element 62 and the heating unit 63 may be changed. 63 does not need to cover the whole area of the deodorizing element 62.
That is, the part where the deodorizing element 62 always faces the heating unit 63 may be a limited portion, so that the air flow through the heating unit 63 through the deodorizing element 62 is minimized. Thereby, it is possible to flow more air with respect to the deodorizing element 62, and more odor can be removed from the air at once.
　更に、脱臭エレメント６２と加熱ユニット６３の相対的位置関係を変更できるので、脱臭エレメント６２の各部位に対して、確実に加熱ユニット６３を対向させて加熱することが可能である。
　これにより、脱臭エレメント６２の各部位間の加熱ムラを少なくでき、脱臭エレメント６２の脱臭能力を効率よく回復することが可能である。 Furthermore, since the relative positional relationship between the deodorizing element 62 and the heating unit 63 can be changed, the heating unit 63 can be reliably opposed to each part of the deodorizing element 62 and heated.
Thereby, the heating nonuniformity between each site | part of the deodorizing element 62 can be decreased, and the deodorizing capability of the deodorizing element 62 can be recovered | restored efficiently.
　更に、空気清浄機Ａの吸込口１１は本体の前面に形成され、吹出口４２は本体の側面、天面、又は背面のいずれかに形成されている。
　このように構成することにより、臭気の発生源に対して、大きく開口する吸込口１１を対向しやすいので、より速く臭気を吸込み、室内空気から臭気を除去することができる。
　また、吹出口１１が本体の側面、天面、又は背面のいずれかに形成されるので、臭気の発生源に清浄された空気が流れ難く、臭気の拡散を防止することができる。 Furthermore, the air inlet 11 of the air cleaner A is formed in the front surface of the main body, and the air outlet 42 is formed in any one of the side surface, the top surface, or the back surface of the main body.
By comprising in this way, since the suction opening 11 which opens large is easy to oppose with respect to the generation source of an odor, an odor can be suck | inhaled faster and an odor can be removed from indoor air.
Moreover, since the blower outlet 11 is formed in any one of the side surface, the top | upper surface, or the back surface of a main body, the purified air cannot flow easily to the generation | occurrence | production source of an odor, and diffusion of an odor can be prevented.
　更に、脱臭エレメント６２は、本体ケースＣに回動可能に支持され、加熱ユニット６３は、脱臭エレメント６２の表面に近接して本体ケースＣに固定されている。
　これにより、ヒーターユニット６３ａ発熱する部位である加熱ユニット６３が本体ケースＣの内部を動かないことから、発熱させるための電源を供給する配線の取り回しや高温の部位が本体ケースＣの内部で位置を変えることによる本体ケースＣ内部の広範囲にわたる熱対策を考慮する必要がない。
　また、脱臭エレメント６２が回動することで、加熱ユニット６３と対向する面を変えるので、１つの方向にだけ脱臭エレメント６２を動かすだけで、ムラ無く脱臭エレメント６２の全面を加熱ユニット６３に対向させることができる。 Further, the deodorizing element 62 is rotatably supported by the main body case C, and the heating unit 63 is fixed to the main body case C in the vicinity of the surface of the deodorizing element 62.
Accordingly, the heating unit 63 that generates heat from the heater unit 63a does not move inside the main body case C. Therefore, the wiring for supplying power to generate heat and the high-temperature portion are positioned inside the main body case C. It is not necessary to consider a wide range of heat countermeasures inside the main body case C by changing.
Moreover, since the surface facing the heating unit 63 is changed by the rotation of the deodorizing element 62, the entire surface of the deodorizing element 62 is made to face the heating unit 63 evenly by moving the deodorizing element 62 only in one direction. be able to.
　更に、脱臭エレメント６２の形状は円板形状であるので、脱臭エレメント６２の回転軸方向から見た面積に対して、脱臭エレメント６２が回転する回転領域を最小にすることができる。
　つまり、本体ケースＣの内部の脱臭エレメント６２の配置領域を小さくすることができる。 Furthermore, since the shape of the deodorizing element 62 is a disk shape, the rotation area | region where the deodorizing element 62 rotates with respect to the area seen from the rotating shaft direction of the deodorizing element 62 can be minimized.
That is, the arrangement area of the deodorizing element 62 inside the main body case C can be reduced.
　また、脱臭エレメント６２は回転することで加熱ユニット６３と対向する面を変えることから、脱臭エレメント６２の形状が円板形状であれば、加熱ユニット６３のヒーターユニット６３ａは、脱臭エレメント６２の直径方向の大きさが、少なくとも脱臭エレメント６２の回転半径と同じか、これより小さいもので、脱臭エレメント６２の多くの領域を加熱することが可能である。 Moreover, since the surface which opposes the heating unit 63 is changed by rotating the deodorizing element 62, if the shape of the deodorizing element 62 is a disk shape, the heater unit 63a of the heating unit 63 is in the diameter direction of the deodorizing element 62. It is possible to heat many areas of the deodorizing element 62 with a size of at least the same as or smaller than the turning radius of the deodorizing element 62.
　更に、脱臭エレメント６２の形状が円板形状であるので、上記の効果を実現する構成を有しながらも、円形状は矩形の開口である本体ケースＣの開口面積に対して、最も大きな領域を形成することが可能であることから、脱臭を可能とする領域をより大きく形成することができる。
　これにより、より多くの空気が脱臭エレメント６２を通って流れることができるので、脱臭力を維持しながら風量を大きくすることができる。 Furthermore, since the shape of the deodorizing element 62 is a disc shape, the circular shape has the largest area with respect to the opening area of the main body case C, which is a rectangular opening, while having a configuration that achieves the above effect. Since it can be formed, a region allowing deodorization can be formed larger.
Thereby, since more air can flow through the deodorizing element 62, the air volume can be increased while maintaining the deodorizing power.
　更に、脱臭エレメント６２には、アンモニアの分解機能がある触媒を表面に塗布又は含浸させている。これにより、ペット臭や病院や介護施設や介護現場などにおける介護臭をすばやく脱臭することが可能な空気清浄機を構成することが可能となる。
　特に本実施の形態であれば、短時間の間に、より多くの空気から臭気を取り除くことができるので、病院や介護施設など多くの人が利用する場所における介護などの臭いのトラブルを迅速に解決することが可能である。 Further, the deodorizing element 62 is coated or impregnated with a catalyst capable of decomposing ammonia. This makes it possible to configure an air purifier that can quickly deodorize pet odors and care odors in hospitals, care facilities, and care sites.
Especially in this embodiment, it is possible to remove odor from more air in a short time, so it is possible to quickly deal with odor problems such as nursing care in places where many people use such as hospitals and nursing care facilities. It is possible to solve.
　また、脱臭エレメントは、アンモニアを吸着する触媒をハニカムコアの表面に塗布又は含浸させ、その表面から触媒が剥がれ落ちるのを防止するコーティング処理を行っているので、移動時や運転時の振動で、ハニカムコアから触媒が剥がれ落ちない。
　これにより、本体ケースＣの内部をハニカムコアから剥がれ落ちた触媒で汚染する虞がない。 In addition, the deodorizing element is coated or impregnated with a catalyst that adsorbs ammonia on the surface of the honeycomb core, and a coating treatment is performed to prevent the catalyst from peeling off from the surface. The catalyst does not peel off from the honeycomb core.
Thereby, there is no possibility that the inside of the main body case C is contaminated with the catalyst peeled off from the honeycomb core.
　更に、送風手段である送風ファンは通風路内部に位置し、脱臭エレメント６２は、通風路Ｒの中で送風ファン４４の上流側に位置し、送風ファン４４と脱臭エレメント６２の間に、加熱ユニット６３が位置している。
　このように構成されているので、脱臭エレメント６２と送風ファン４４の開口４４ｄの周囲で生じる圧損（空気の流れの損失）を低減するために設けられたスペースを、加熱ユニット６３の配置位置として用いることができる。 Further, the blower fan, which is a blower, is located inside the ventilation path, and the deodorizing element 62 is located on the upstream side of the blower fan 44 in the ventilation path R, and between the blower fan 44 and the deodorizing element 62, the heating unit 63 is located.
Since it is configured in this way, the space provided to reduce the pressure loss (loss of air flow) generated around the deodorizing element 62 and the opening 44 d of the blower fan 44 is used as the arrangement position of the heating unit 63. be able to.
　更に、加熱ユニット６３は、脱臭エレメント６２に対向する側が開口し、所定の内部空間を有するケース６３ｂと、このケース６３ｂ内部空間に位置し開口を通じて熱を放射する電気ヒーターユニット６３ａとを備え、ヒーターユニット６３ａは、所定時間通電された場合、脱臭エレメント６２の対向した部分を所定温度まで上昇させることができる加熱能力に設定してある。これにより、脱臭エレメント６２に吸着した臭気を除去することが可能である。
　また、上記のケース６３ｂの形状は扇形となっている。これにより、脱臭エレメント６２を覆う面積を必要最小限とすることができる。尚、扇形の開角は、脱臭エレメント６２を回転させる際の１回の回転角度を目安に構成されている。 Further, the heating unit 63 includes a case 63b having a predetermined internal space that is open on the side facing the deodorizing element 62, and an electric heater unit 63a that is located in the internal space of the case 63b and radiates heat through the opening. The unit 63a is set to a heating capacity capable of raising the facing portion of the deodorizing element 62 to a predetermined temperature when energized for a predetermined time. Thereby, the odor adsorbed on the deodorizing element 62 can be removed.
Moreover, the shape of the case 63b is a sector shape. Thereby, the area which covers the deodorizing element 62 can be minimized. The fan-shaped opening angle is configured based on a single rotation angle when the deodorizing element 62 is rotated.
　更に、制御部４７には、位置変更手段である駆動手段６４を所定のタイミングで駆動して、脱臭エレメント６２を回動させる制御プログラムを内蔵している。
　これにより、脱臭エレメント６２を加熱する際に、制御部４７により自動的に脱臭エレメント６２の脱臭すべき部位を加熱ユニット６３に対向することができる。 Further, the control unit 47 has a built-in control program for driving the driving means 64 as position changing means at a predetermined timing to rotate the deodorizing element 62.
Thereby, when the deodorizing element 62 is heated, the control unit 47 can automatically face the portion of the deodorizing element 62 to be deodorized to the heating unit 63.
　また、上記の制御プログラムは、駆動手段６４を所定のタイミングで駆動して脱臭エレメントを所定の回転角度だけ回動した後停止させ、その停止状態で加熱ユニットを所定時間通電する処理ステップを有する。
　これにより、脱臭エレメント６２の回転から加熱に至る一連の動作を制御部４７により自動的に行うことができる。 The control program includes a processing step of driving the driving means 64 at a predetermined timing to stop the deodorizing element after being rotated by a predetermined rotation angle and energizing the heating unit for a predetermined time in the stopped state.
Thereby, a series of operations from the rotation of the deodorizing element 62 to the heating can be automatically performed by the control unit 47.
　更に、通風路Ｒは、脱臭エレメント６２の下流側で上方に屈曲していると共に、この屈曲部に送風ファン４４を配置し、この送風ファン４４は、水平方向に伸びる回転軸を中心に回転し、本体ケースＣの正面側から導入した空気を上方へも送り出す多翼式ファンである。
　このような多翼式ファン（シロッコファン）は、ファンの回転軸方向から空気を取り込み、ファンの径方向へと取り込んだ空気を吐き出すので、室内空気を本体ケースＣの前面から後方への直線的な流れを作り出すと共に、吹出口４２に向けて効率よく風の向きを変えることができる。 Further, the ventilation path R is bent upward on the downstream side of the deodorizing element 62, and a blower fan 44 is disposed at the bent portion, and the blower fan 44 rotates around a rotating shaft extending in the horizontal direction. The multi-blade fan that sends air introduced from the front side of the main body case C upwards.
Such a multi-blade fan (sirocco fan) takes in air from the rotation axis direction of the fan and exhales the air taken in the radial direction of the fan. Can be created, and the direction of the wind can be efficiently changed toward the air outlet 42.
　更に、加熱ユニット６３は、脱臭エレメント６２の回転中心より下側に位置するように本体に取付けられている。
　このように、ヒーターユニット６３ａなどを有するある程度重量がある加熱ユニットを低い位置に配置することで、空気清浄機Ａの重心を低くすることができる。これにより、床面に安定して設置することができる空気清浄機Ａを構成することができる。 Further, the heating unit 63 is attached to the main body so as to be positioned below the rotation center of the deodorizing element 62.
Thus, the center of gravity of the air purifier A can be lowered by disposing the heating unit having a certain amount of weight including the heater unit 63a or the like at a low position. Thereby, the air cleaner A which can be stably installed on the floor surface can be configured.
　更に、開口６５ａの位置は、本体ケースＣの正面の上下方向の中央に位置し、本体ケースＣの正面視における投影面積Ａと、吸込口の正面視における面積Ｂとの関係が、
　「Ｂ≧０．６Ａ」
となるように構成されている。
　この関係は、本体ケースＣの正面視の面積に対して、開口６５ａ吸込口が室内空気を最大限取り込める関係であり、より室内空気を多く取り込み脱臭エレメント６２へ流すことが可能な空気清浄機を構成することができる。 Furthermore, the position of the opening 65a is located at the center in the vertical direction of the front surface of the main body case C, and the relationship between the projection area A in the front view of the main body case C and the area B in the front view of the suction port is
“B ≧ 0.6A”
It is comprised so that it may become.
This relationship is such that the opening 65a suction port can take in room air to the maximum with respect to the area of the main body case C in front view, and an air purifier that can take in more room air and flow it to the deodorizing element 62. Can be configured.
　更に、空気清浄機Ａが運転時に転倒することにより、危険な状態にならないために、転倒を検知する振動センサー４７ａを制御部４７と共に本体内部の下側に設けたので、振動の触れ幅が、本体ケースの上方に設置した場合に比べて小さく、通常時の微弱振動にも検知してしまう恐れが小さくなった。 Furthermore, since the air purifier A does not enter a dangerous state due to falling during operation, the vibration sensor 47a for detecting the falling is provided on the lower side inside the main body together with the control unit 47. It is smaller than the case where it is installed above the main body case, and the possibility of detecting weak vibrations during normal operation is reduced.
　更に、通風路Ｒには、脱臭エレメント６２より上流側に塵埃濾過フィルター１２，１３が設置されており、本体ケースＣの前面には、通気性を有する枠体である前パネル１０が着脱可能に取り付けられ、この枠体を本体ケースＣから取り外した状態で、塵埃濾過フィルターを本体ケースＣ前方に取り出すことが可能な構成である。
　このように構成することにより、本体ケースＣの前側から塵埃濾過フィルターを着脱することができるので、大きめな塵埃が付着しやすい塵埃濾過フィルターのメンテナンス性を向上することができる。 Furthermore, dust filtration filters 12 and 13 are installed on the upstream side of the deodorizing element 62 in the ventilation path R, and the front panel 10 that is a frame having air permeability can be attached to and detached from the front surface of the main body case C. The dust filtering filter can be taken out to the front of the main body case C in a state where the frame body is attached and removed from the main body case C.
With this configuration, the dust filtration filter can be attached and detached from the front side of the main body case C, so that it is possible to improve the maintainability of the dust filtration filter to which large dust tends to adhere.
　また、前パネル１０は、前ケース２０上部に配置した凹部２８ａと、前パネル１０に設けられたラッチ受部１０ｂと前ケース２０に設けられたラッチ部２５ａからなるラッチ機構により、前ケース２０に固定され、前ケース２０に設けられた前パネル１０を前方に押圧するばね機構を設けたので、本体の寸法のばらつきにより移動の振動でガタツキや外れの恐れがない。 Further, the front panel 10 is attached to the front case 20 by a latch mechanism including a concave portion 28 a disposed on the upper portion of the front case 20, a latch receiving portion 10 b provided on the front panel 10, and a latch portion 25 a provided on the front case 20. Since the spring mechanism that is fixed and presses forward the front panel 10 provided on the front case 20 is provided, there is no risk of rattling or detachment due to vibration of movement due to variations in the dimensions of the main body.
（本体ケースＣの外郭について）
　次に、図１５～図１７を参照して、本体ケースＣの外郭について説明する。
　空気清浄機Ａは、外郭を本体ケースＣと、この本体ケースＣに設けられる脱臭部６０などの各種機能部品により構成されている。
　この本体ケースＣは、樹脂により形成されており、前パネル１０と前ケース２０と後ケース４０などの複数の部品により構成され、正面及び側面の平面形状が、縦長方形の外殻形状をなしている。 (Outside of the main body case C)
Next, the outline of the main body case C will be described with reference to FIGS.
The air purifier A is composed of a main body case C and various functional parts such as a deodorizing unit 60 provided in the main body case C.
The main body case C is formed of a resin and is composed of a plurality of parts such as the front panel 10, the front case 20, and the rear case 40, and the planar shape of the front and side surfaces is a vertically rectangular outer shell. Yes.
　そして、本体ケースＣの底部には、４つの車輪９０が設けられている。４つの車輪は、前ケース２０の底部に２個、後ケース４０の底部に２個ずつ設けられ、本体ケースＣを前側から見て、本体ケースＣの中心に左右対称となるようにそれぞれ左右に１つずつ配置されている。 Further, four wheels 90 are provided at the bottom of the main body case C. Two wheels are provided at the bottom of the front case 20 and two at the bottom of the rear case 40, respectively, and the left and right sides of the main body case C are symmetric with respect to the center of the main body case C when viewed from the front side. One by one.
　更に、前ケース２０を構成するフレーム２１の上辺の上部の後側には、使用者が空気清浄機Ａを移動する際に把持するアーチ形状のハンドル９１が設けられている。
　このハンドル９１は、本体ケースＣの左右方向に長い棒形状の握り部９１ａを有している。この握り部９１ａの左右の中心軸は、本体ケースＣの天面中央で、かつ左右方向に長く向くように設置されている。 Further, an arch-shaped handle 91 that is gripped when the user moves the air cleaner A is provided on the rear side of the upper part of the upper side of the frame 21 constituting the front case 20.
This handle 91 has a long bar-shaped grip 91 a in the left-right direction of the main body case C. The left and right central axes of the grip portion 91a are installed at the center of the top surface of the main body case C and so as to be long in the left-right direction.
　また、ハンドル９１の本体ケースＣに対する前後方向に位置は、加熱ユニット６３と送風ファン４４の間となるように前ケース２０の後側に位置している。また、握り部９１ａの床面からの高さＬは、７００ｍｍ以下の範囲に位置するように構成されている。
　このように各部が配置された状態において、車輪９０は少なくとも握り部９１ａの長手方向に回転自在となるように構成されている。 Further, the position of the handle 91 in the front-rear direction with respect to the main body case C is located on the rear side of the front case 20 so as to be between the heating unit 63 and the blower fan 44. Moreover, the height L from the floor surface of the grip part 91a is comprised so that it may be located in the range of 700 mm or less.
Thus, in the state where each part is arranged, the wheel 90 is configured to be rotatable at least in the longitudinal direction of the grip part 91a.
　更に図４を参照すると、ハンドル９１の下方であって、前ケース２０の後面上側の部位が前方に窪む凹部が形成されている。この凹部は、本体ケースＣの手掛け部２７となる部位である。
　この手掛け部２７は、本体ケースＣの左右中心に位置し、ハンドル９１の握り部９１ａと上下に重なる位置関係となっている。従って、手掛け部２７もハンドル９１と同様に、本体ケースＣの前後方向に対する位置は、加熱ユニット６３と送風ファン４４の間となっている。
　また、後ケース４０の上面は、前ケース２０の上面より一段低く構成されており、この様に構成することにより現れる前ケース２０の後面上部に手掛け部２７が開口している。　 Further, referring to FIG. 4, a recessed portion is formed below the handle 91 and in which a portion of the rear surface upper side of the front case 20 is recessed forward. This concave portion is a portion that becomes the handle portion 27 of the main body case C.
The handle portion 27 is located at the center of the main body case C, and has a positional relationship that overlaps with the grip portion 91a of the handle 91 in the vertical direction. Therefore, similarly to the handle 91, the handle portion 27 is located between the heating unit 63 and the blower fan 44 in the front-rear direction of the main body case C.
Further, the upper surface of the rear case 40 is configured to be one step lower than the upper surface of the front case 20, and the handle portion 27 is opened at the upper portion of the rear surface of the front case 20 that appears by this configuration.
　また、本実施の形態の空気清浄機Ａは、ハンドル９１の握り部９１ａの床面からの高さＬが７００ｍｍ以下となるように構成されている。
　このように構成されているので、日本人の成人の指節点高（人が床面に立った状態で、床面から中指指節点までの垂直距離）の平均は、男性が約６９５ｍｍ、女性が約６３２ｍｍ、全体が約６６２ｍｍであることから、性別に関係なく、使用者が大きくかがむことなく、握りやすいハンドル９１の高さとなっている。 Moreover, the air cleaner A of this Embodiment is comprised so that the height L from the floor surface of the grip part 91a of the handle 91 may be 700 mm or less.
Because of this structure, the average finger joint height (vertical distance from the floor to the middle finger joint when a person is standing on the floor) is about 695 mm for men and about 695 mm for women. Since it is about 632 mm and the whole is about 662 mm, the height of the handle 91 is easy to grip without being greatly bent by the user regardless of gender.
　更に、本実施の形態の空気清浄機Ａの奥行きＳは、約３００ｍｍとなっている。
　このように構成されているので、日本人の成人の肩幅の平均は、男性が約４２６ｍｍ、女性が約３９４ｍｍ、全体が約４０９ｍｍであることから、性別に関係なく、空気清浄機Ａを側方より押し引きする際に、人の肩幅内に納まる。
　これにより、空気清浄機Ａは、狭い通路や場所においても、移動を容易に行うことができる。 Furthermore, the depth S of the air cleaner A of the present embodiment is about 300 mm.
Because it is configured in this way, the average shoulder width of Japanese adults is about 426 mm for men, about 394 mm for women, and about 409 mm for the whole. When pushing and pulling more, it fits within the shoulder width of a person.
Thereby, the air cleaner A can move easily even in a narrow passage or place.
　更に、一般家庭の廊下幅が約８５０ｍｍ～９００ｍｍであることから、空気清浄機Ａを横に向けて廊下においた場合、約５５０ｍｍ～６００ｍｍのスペースを確保することができる。
　従って、空気清浄機Ａを一般家庭の廊下に設置しても、人や物が十分に通るだけのスペースを確保することができる。 Furthermore, since the corridor width of a general household is about 850 mm to 900 mm, a space of about 550 mm to 600 mm can be secured when the air cleaner A is placed sideways in the corridor.
Therefore, even if the air purifier A is installed in a general household corridor, it is possible to secure a space enough for people and objects to pass.
　更に、介護施設の廊下幅が約１８００ｍｍ以上あることから、空気清浄機Ａを横に向けて廊下においた場合、約１５００ｍｍのスペースを確保することができる。
　従って、空気清浄機Ａを介護施設の廊下に設置しても、人や物が十分に通るだけのスペースを確保することができる。
　また、一般的に用いられる車椅子は幅が約７００ｍｍであることから、介護施設の廊下に空気清浄機Ａが設置されていても、車椅子同士のすれ違いが可能である。 Furthermore, since the corridor width of the care facility is about 1800 mm or more, when the air cleaner A is placed sideways in the hallway, a space of about 1500 mm can be secured.
Therefore, even if the air purifier A is installed in the corridor of the care facility, it is possible to secure a space enough for people and things to pass.
Moreover, since the wheelchair generally used is about 700 mm in width, even if the air purifier A is installed in the corridor of the care facility, the wheelchairs can pass each other.
　以上のように構成された空気清浄機Ａは、次のように電源コードを収納する。
　図２０を参照すると、本体ケースＣの背面となる後ケース４０の背面には、上下一対のフック５０が設けられる。この様に設けられた上下一対のフック５０に電源コードＫを掛け渡すように巻回することにより、電源コードＫは本体ケースＣに保持される。
　ここで、一方のフックを他方のフックに近づくことができるように構成すれば、フックに巻つけてあるコードを外す際に、一方のフックを他方のフックに近づけることで、巻回してある電源コードをまとめてフックからはずすことができ、迅速に電源コードを広げることが可能となる。
　尚、フックにコードを巻きつける構成を説明したが、図２１のように、本体にコードリールを配置してもよい。 The air purifier A configured as described above stores the power cord as follows.
Referring to FIG. 20, a pair of upper and lower hooks 50 are provided on the back surface of the rear case 40 that is the back surface of the main body case C. The power cord K is held in the main body case C by winding the power cord K around the pair of upper and lower hooks 50 provided in this way.
Here, if one hook is configured to be able to come close to the other hook, when the cord wound around the hook is removed, the power supply that has been wound can be obtained by bringing one hook closer to the other hook. The cords can be collectively removed from the hook, and the power cord can be quickly spread.
In addition, although the structure which winds a cord around a hook was demonstrated, you may arrange | position a cord reel to a main body like FIG.
　以上のように本体外郭を構成することにより、ハンドル９１の握り部９１ａの長手方向に車輪が回転自在となるように本体ケースＣに設けられることで、大型な空気清浄機Ａであっても容易に押し引きすることが可能となる。
　特に、前ケース２０に脱臭エレメント６２や加熱ユニット６３などを配置し、後ケースに送風ファン４４や吹出口４２を配置し、ハンドル９１を前ケースと後ケースの接合部に構成した。 By constructing the main body outline as described above, the main body case C is provided so that the wheels are rotatable in the longitudinal direction of the grip portion 91a of the handle 91, so that even a large air cleaner A can be easily used. It is possible to push and pull.
In particular, the deodorizing element 62 and the heating unit 63 are disposed in the front case 20, the blower fan 44 and the blowout port 42 are disposed in the rear case, and the handle 91 is configured at the joint between the front case and the rear case.
　これにより、比較的重量の大きい部品を前ケースと後ケースにバランスよく配置し、その接合部にハンドルを構成することにより、ハンドル９１を握って空気清浄機を押し引きするときに、重量のバランスが比較的取れた位置を支点に空気清浄機Ａを動かすことができる。
　また、後ケースに吹出口４２を配置したので、ハンドル９１が吹出口４２からの気流を邪魔することがない。 Thereby, relatively heavy parts are arranged in a balanced manner in the front case and the rear case, and a handle is formed at the joint portion, so that when the air cleaner is pushed and pulled while holding the handle 91, the weight balance is achieved. The air purifier A can be moved using the position where the air is relatively removed as a fulcrum.
Moreover, since the blower outlet 42 is arrange | positioned in the rear case, the handle | steering-wheel 91 does not obstruct the airflow from the blower outlet 42. FIG.
　また、ハンドル９１から下方に位置する本体ケースＣ部分に別途手掛け部２７を設置した。
　ハンドル９１の高さは、日本人の成人の指節点高（人が床面に立った状態で、床面から中指指節点までの垂直距離）の平均より、使用者が大きくかがむことなく、握りやすい高さに設定したが、背の低い人には、握りにくい場合がある。そのときには、ハンドル高さより下方にある手掛けを利用すると運びやすい。 Further, the handle portion 27 is separately installed in the main body case C portion located below the handle 91.
The height of the handle 91 is gripped without the user crouching more than the average of the finger joint height (vertical distance from the floor surface to the middle finger joint when a person is standing on the floor) of a Japanese adult. Although the height is set to be easy, it may be difficult for a short person to grasp. At that time, it is easy to carry if a handle below the handle height is used.
　更に、本体ケースＣにおいて、手掛け部２７の位置がハンドル９１と同様にバランスのよい位置となっているので、手掛け部２７を用いて空気清浄機Ａを持ち運ぶ場合でも、ハンドル９１を用いた場合と同様に運びやすい構成となっている。
　更に、後ケース４０の上面は、前ケース２０の上面より一段低く構成されており、この様に構成することにより現れる前ケース２０の後面上部に手掛け部２７が開口している。　 Further, in the main body case C, the position of the handle portion 27 is in a well-balanced position like the handle 91. Therefore, even when the air purifier A is carried using the handle portion 27, the handle 91 is used. Similarly, it is easy to carry.
Furthermore, the upper surface of the rear case 40 is configured to be one step lower than the upper surface of the front case 20, and a handle portion 27 is opened at the upper portion of the rear surface of the front case 20 that appears by this configuration.
　これにより、前ケース２０において、通風路Ｒの外に手掛け部２７が配置されるので、通風路Ｒを狭めることがない。また、後ケース４０に手掛け部２７を設けないことから、吹出口４２の開口面積を狭めたり、後ケース４０内部の通風路Ｒを狭めたりしない。
　つまり、上記のように手掛け部２７を本体ケースＣに設けることにより、通風路Ｒや吹出口４２など、空気の流れる領域の制約が生じない構成となっている。 Thereby, in the front case 20, since the handle part 27 is arrange | positioned outside the ventilation path R, the ventilation path R is not narrowed. Further, since the handle portion 27 is not provided in the rear case 40, the opening area of the air outlet 42 is not narrowed, and the ventilation path R inside the rear case 40 is not narrowed.
That is, by providing the handle portion 27 in the main body case C as described above, there is no restriction on the air flow region such as the ventilation path R and the air outlet 42.
　更に、本体ケースＣの背面に、コード巻きつけフックを配置し、プラグコードを巻きつけられるようにしたので、本体をキャスターで移動中に、プラグコードを踏んでしまったり、それが原因で転倒したりする恐れがなくなった。 In addition, a cord wrapping hook is arranged on the back of the main unit case C so that the plug cord can be wound, so that the plug cord may be stepped on while the main unit is being moved by a caster, or it may fall over. There is no longer any fear of losing.
　また、コード巻きつけフックの代わりに、本体にコードリールを配置すると、更に使いやすくなる。 Also, if a cord reel is placed on the main body instead of the cord wrapping hook, it will be easier to use.
