A ventilation path R is formed in the main body case 1. The ventilation path R reaches the blower outlet 1b through the blower means 2 from the inlet 1a. Deodorizing means 3 is provided over substantially the entire area inside one surface of the main body case 1. The deodorizing means 3 includes two or more different substrates. For example, the deodorizing means 3 includes base materials 3a and 3b. Driving means (not shown) such as a motor is attached to the deodorizing means 3.

脱臭手段３の下部の下流側には、加熱手段４が設けられる。脱臭手段３と加熱手段４との間には、微小な加熱空間が形成される。加熱手段４と当該加熱手段４と対向する脱臭手段３を含めた空間を脱臭手段３の上流側から覆うように、断熱材５が設けられる。本体ケース１の上面の内側近傍には、制御手段６（制御基板）６が設けられる。制御手段６は、送風手段２、駆動手段、加熱手段４に配線（図示せず）を介して接続される。 On the downstream side of the lower part of the deodorizing means 3, a heating means 4 is provided.

次に、図３を用いて、脱臭手段３と加熱手段４とを説明する。
図３はこの発明の実施の形態１における脱臭装置の要部の斜視図である。 Next, the deodorizing means 3 and the heating means 4 will be described with reference to FIG.
FIG. 3 is a perspective view of a main part of the deodorizing apparatus according to Embodiment 1 of the present invention.

図３に示すように、脱臭手段３は、円形状に形成される。脱臭手段３において、基材３ａの熱伝導率は、基材３ｂの熱伝導率よりも高い。基材３ａは、通風路Ｒにおける空気の流れの進行方向に対して下流側に配される。基材３ｂは、通風路Ｒにおける空気の流れの進行方向に対して上流側に配される。基材３ａと基材３ｂは、互いの対向面を密接した状態で配される。基材３ａは、基材３ｂによって複数の領域に分割される。なお、基材３ａ及び基材３ｂは、脱臭手段３に着脱自在に取り付けられてもよい。 As shown in FIG. 3, the deodorizing means 3 is formed in a circular shape. In the deodorizing means 3, the heat conductivity of the base material 3a is higher than the heat conductivity of the base material 3b. The base material 3a is disposed on the downstream side with respect to the direction of air flow in the ventilation path R. The base material 3b is arranged on the upstream side with respect to the traveling direction of the air flow in the ventilation path R. The base material 3a and the base material 3b are arranged in a state where the opposing surfaces are in close contact with each other. The base material 3a is divided into a plurality of regions by the base material 3b. In addition, the base material 3a and the base material 3b may be detachably attached to the deodorizing means 3.

例えば、図３及び図４に示すように、４個の扇状の基材３ａとこれらを仕切る基材３ｂとは、加熱手段４側で段にならずに同一平面上に並ぶように配される。脱臭手段３は、空気が通過するように形成される。例えば、ハニカム状、フィン状、メッシュ状、板状に形成される。脱臭手段３には、触媒が添着される。触媒は、加熱により吸着した臭気物質を酸化分解する機能を備える。 For example, as shown in FIGS. 3 and 4, the four fan-shaped base materials 3 a and the base material 3 b that partitions them are arranged on the same plane without being stepped on the heating means 4 side. . The deodorizing means 3 is formed so that air passes through it. For example, it is formed in a honeycomb shape, a fin shape, a mesh shape, or a plate shape. A catalyst is attached to the deodorizing means 3. The catalyst has a function of oxidizing and decomposing odorous substances adsorbed by heating.

４個の扇状の基材３ａを仕切る基材３ｂは、基材３ｂから基材３ａにあたる部位を切り出すことで構成する。この場合、切り出し部分に後から基材３ａを組み込むことで、脱臭手段３を一体化構造とする。
また、４個の扇状の基材３ａを仕切る基材３ｂは、円柱状の３ｂに仕切り部分にあたる基材３ｂをはめ込むことで構成する。この場合、仕切り部分にあたる基材３ｂは、直方体の一方の短辺が円柱体の円周に沿うように加工され、円柱状の３ｂとは別個に加工される。円柱状の３ｂに仕切り部分にあたる基材３ｂをはめ込むための凹部が、また、仕切り部分にあたる基材３ｂには円柱状の基材３ｂにスライドしてはめ込むことが可能な凸部が設けられ、両者をスライドしてはめ込むことで基材３ｂを一体化構造とし、そこにさらに４個の扇状の基材３ａをはめこむことで脱臭手段３を一体化構造とする。なお、基材３ｂを一体化する際には基材３ｂ間の熱伝導性や通気性を阻害しない接着部材で前面を接着する、あるいは熱伝導性や通気性を阻害する接着部材の場合には部分的に接着することも可能であるが、基材３ｂ間の熱伝導性を考慮した場合には別個の物質により一体化するよりははめ込み構造とすることで単一の基材で一体化することが好ましい。 The base material 3b that partitions the four fan-shaped base materials 3a is configured by cutting out a portion corresponding to the base material 3a from the base material 3b. In this case, the deodorizing means 3 is made into an integrated structure by incorporating the base material 3a into the cutout portion later.
Moreover, the base material 3b which partitions off the four fan-shaped base materials 3a is comprised by inserting the base material 3b which corresponds to a partition part in cylindrical 3b. In this case, the base material 3b corresponding to the partition portion is processed so that one short side of the rectangular parallelepiped is along the circumference of the cylindrical body, and is processed separately from the cylindrical 3b. A concave portion for fitting the base material 3b corresponding to the partition portion into the cylindrical 3b is provided, and a convex portion that can be slid into the cylindrical base material 3b and provided to the base material 3b corresponding to the partition portion is provided. The base material 3b is made into an integrated structure by sliding and fitting, and the deodorizing means 3 is made into an integrated structure by inserting four fan-like base materials 3a therein. When the base material 3b is integrated, the front surface is bonded with an adhesive member that does not inhibit the thermal conductivity and air permeability between the base materials 3b, or in the case of an adhesive member that inhibits the thermal conductivity and air permeability. Although partial adhesion is possible, in consideration of the thermal conductivity between the substrates 3b, it is integrated with a single substrate by adopting a fitting structure rather than integrating with separate materials. It is preferable.

基材３ａを基材３ｂにはめ込むためには、いずれか一方に凹部、他方に凸部を設けておき、スライド式に挿入する、あるいは耐熱性、臭気非発生性、通気性を阻害しない少なくともいずれか一つの特徴を有する無機、あるいは有機接着部材で一体化構造とする。 In order to fit the base material 3a into the base material 3b, a concave portion is provided on one side, and a convex portion is provided on the other side, and the base material 3a is inserted in a sliding manner, or at least any one that does not impair heat resistance, odor generation, and air permeability An integrated structure is made of an inorganic or organic adhesive member having one of these characteristics.

脱臭手段３の基材の種類に応じ、異なる種類の触媒を用いてもよい。例えば、金属をコルゲート状に形成した基材３ａには、酸化マンガンなどの金属酸化物を添着させればよい。ゼオライトやセラミックをハニカム状に形成した基材３ｂには、酸化マンガン及び酸化銅を添着させればよい。酸化マンガンは硫黄成分、酸化銅は窒素成分の酸化分解を得意とするなど、触媒各個に特徴があることから複数の触媒を組合せることによって、例えば、糞尿臭に含まれるアンモニアの脱臭及び酸化分解性能を向上させることが可能である。
また、白金のように自身が熱伝導性がよくかつ、臭気物質の酸化分解性能を有する触媒としても作用する基材を用いることでき、特に基材３ａとして用いると触媒が短時間で昇温して臭気物質を酸化分解することができるため、有効である。 Different types of catalysts may be used depending on the type of base material of the deodorizing means 3. For example, a metal oxide such as manganese oxide may be attached to the base material 3a in which a metal is formed in a corrugated shape. Manganese oxide and copper oxide may be attached to the base material 3b in which zeolite or ceramic is formed in a honeycomb shape. Manganese oxide is good at oxidative decomposition of sulfur component, copper oxide is good at oxidative decomposition of nitrogen component, etc. Each catalyst has its characteristics, so by combining multiple catalysts, for example, deodorization and oxidative decomposition of ammonia contained in manure odor It is possible to improve performance.
Moreover, a base material that has a good thermal conductivity and that also functions as a catalyst having the ability to oxidize and decompose odorous substances such as platinum can be used. In particular, when used as the base material 3a, the temperature of the catalyst increases in a short time. This is effective because it can oxidize and decompose odorous substances.

なお、基材３ａは、金属以外の材質で形成してもよく、熱伝導率が１０Ｗ／（ｍ・ｋ）以上のものがよい。基材３ｂは、セラミックやゼオライト以外の材質で形成してもよく、熱伝導率が低いほど好ましい。 The base material 3a may be formed of a material other than metal, and preferably has a thermal conductivity of 10 W / (m · k) or more. The substrate 3b may be formed of a material other than ceramic or zeolite, and the lower the thermal conductivity, the better.

各基材３ａのうちの一領域は、加熱手段４の全面と対向する。基材３ｂは、通風路Ｒにおける空気の流れの進行方向に対して垂直方向で基材３ａの片面と全面が接し、同一材質により奥行き方向まで隣接した状態で、各基材３ａを仕切る。 One region of each base material 3 a faces the entire surface of the heating means 4. The base material 3b partitions each base material 3a in a state where one surface and the entire surface of the base material 3a are in contact with each other in the direction perpendicular to the air flow direction in the ventilation path R and are adjacent to each other in the depth direction by the same material.

上記脱臭手段３の一面及び他面が切り替わる境界は、図２においては円柱体である脱臭手段３の高さ方向にあたる辺の中央部として図示しているが、脱臭対象とする臭気物質や使用する触媒の種類や、基材３ａ及び３ｂの基材強度などを鑑みて決定してもよい。 The boundary where one side and the other side of the deodorizing means 3 are switched is illustrated as a central portion of the side corresponding to the height direction of the deodorizing means 3 which is a cylindrical body in FIG. You may determine in consideration of the kind of catalyst, the base material strength of the base materials 3a and 3b, etc.

加熱手段４は、扇状に形成される。加熱手段４の中心角は、各基材３ａの中心角よりも広い。加熱手段４の面積及び加える熱量は、熱が脱臭手段３に到達するまでに減少する量等に基づいて、個別に設定される。 The heating means 4 is formed in a fan shape. The central angle of the heating means 4 is wider than the central angle of each substrate 3a. The area of the heating means 4 and the amount of heat to be applied are individually set based on the amount of heat that decreases before reaching the deodorizing means 3.

加熱手段４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 heating means 4 uses a PTC heater which 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.

加熱手段４と脱臭手段３、特に加熱手段４と直接対向する基材３ａの距離は１ｃｍ以下と近接していることが好ましい。ただし、脱臭手段３は回転駆動する構成であるため、回転の動きを阻害しない程度の空間を周辺部材との間に設ける必要がある。
加熱手段４の熱は加熱手段４と脱臭手段３の間の空気を介して伝えられるため、加熱手段４との距離が大きすぎると放熱により伝わる熱量が減衰し、加熱手段４と同等の温度まで脱臭手段３の温度を上昇させることができない。このため、空気層を介して対向する加熱手段４と脱臭手段３の距離は脱臭手段３の回転を阻害せず、かつ可能な限り近接していることが好ましい。 It is preferable that the distance between the heating means 4 and the deodorizing means 3, particularly the base material 3a directly facing the heating means 4 is close to 1 cm or less. However, since the deodorizing means 3 is configured to rotate, it is necessary to provide a space between the peripheral members so as not to hinder the movement of rotation.
Since the heat of the heating unit 4 is transmitted through the air between the heating unit 4 and the deodorizing unit 3, if the distance from the heating unit 4 is too large, the amount of heat transmitted by heat dissipation is attenuated and reaches a temperature equivalent to that of the heating unit 4. The temperature of the deodorizing means 3 cannot be raised. For this reason, it is preferable that the distance between the heating means 4 and the deodorizing means 3 facing each other through the air layer is as close as possible without inhibiting the rotation of the deodorizing means 3.

次に、図４等を用いて、脱臭装置の動作を説明する。
図４はこの発明の実施の形態１における脱臭装置の加熱手段と脱臭手段の配置関係を示す図である。 Next, operation | movement of a deodorizing apparatus is demonstrated using FIG.
FIG. 4 is a diagram showing the positional relationship between the heating means and the deodorizing means of the deodorizing apparatus according to Embodiment 1 of the present invention.

本体ケース１に設けられたスイッチ（図示せず）等が操作されると、制御手段６が送風手段２を動作させる。当該動作によって、吸入口１ａから室内の空気が本体ケース１内に導入される。当該空気は、通風路Ｒを経由して、吹出口１ｂから吹き出される。この際、当該空気内の臭気物質は、脱臭手段３に吸着する。当該吸着により、脱臭手段３の脱臭性能が低下する。 When a switch (not shown) or the like provided in the main body case 1 is operated, the control means 6 operates the air blowing means 2. By this operation, indoor air is introduced into the main body case 1 from the suction port 1a. The air is blown out from the outlet 1b via the ventilation path R. At this time, the odorous substance in the air is adsorbed by the deodorizing means 3. Due to the adsorption, the deodorizing performance of the deodorizing means 3 is lowered.

その後、所定のタイミングで、脱臭手段３の脱臭性能回復動作が行われる。所定のタイミングとしては、例えば、１日の脱臭動作が終わった後とする。この場合、加熱手段４と対向する部位のみについて回復動作が行なわれる。それにより、加熱手段４による１日あたりの消費電力を抑えることができる。 Thereafter, the deodorizing performance recovery operation of the deodorizing means 3 is performed at a predetermined timing. The predetermined timing is, for example, after the daily deodorizing operation is finished. In this case, the recovery operation is performed only on the part facing the heating means 4. Thereby, the power consumption per day by the heating means 4 can be suppressed.

尚、再生動作を優先する場合には、加熱手段４と対向する部位の再生動作が終了したら、制御部により脱臭手段３を回転させ、先に再生動作が完了した部位に隣接する部位の再生を連続して行ってもよい。この場合、複数の部位が短時間で再生される。 In addition, when giving priority to the regenerating operation, when the regenerating operation of the part facing the heating unit 4 is finished, the control unit rotates the deodorizing unit 3 to regenerate the part adjacent to the part where the regenerating operation has been completed first. You may carry out continuously. In this case, a plurality of parts are reproduced in a short time.

所定のタイミングの他の例としては、運転開始からの累積時間が所定時間を超えた場合や、前回行った脱臭手段３の脱臭性能の性能回復動作からの累積時間が所定時間を越えた場合等としてもよい。当該脱臭性能回復動作は、送風手段２の動作と並行して行ってもよい。 Other examples of the predetermined timing include a case where the accumulated time from the start of operation exceeds a predetermined time, a case where the accumulated time from the performance recovery operation of the deodorizing performance of the deodorizing means 3 performed previously exceeds a predetermined time, etc. It is good. The deodorizing performance recovery operation may be performed in parallel with the operation of the air blowing means 2.

脱臭手段３の脱臭性能回復動作として、制御手段６は、加熱手段４と脱臭手段３の相対位置を制御する。具体的には、図３に示すように、制御手段６は、加熱手段４が基材３ｂに囲われた基材３ａのひとつの全面と対向するように、駆動手段を介して脱臭手段３を回転させる。例えば、図４に示すように、制御手段６は、鉛直投影面上で加熱手段４の一縁部が当該加熱手段４と対向する基材３ａの一側の基材３ｂと重なるように、脱臭手段３を回転させる。また、制御手段６は、当該基材３ａの両側の基材３ｂが加熱手段４の両縁部の内側に配されるように、脱臭手段３を回転させる場合もある。その結果、図３に示すように、当該基材３ａが加熱領域Ａとなるように配される。この状態で、制御手段６は、脱臭手段３の回転を停止させる。 As the deodorizing performance recovery operation of the deodorizing means 3, the control means 6 controls the relative position of the heating means 4 and the deodorizing means 3. Specifically, as shown in FIG. 3, the control means 6 controls the deodorizing means 3 via the drive means so that the heating means 4 faces one whole surface of the base material 3a surrounded by the base material 3b. Rotate. For example, as shown in FIG. 4, the control means 6 performs deodorization so that one edge of the heating means 4 overlaps the base material 3 b on one side of the base material 3 a facing the heating means 4 on the vertical projection plane. The means 3 is rotated. Moreover, the control means 6 may rotate the deodorizing means 3 so that the base materials 3b on both sides of the base material 3a are arranged inside the both edges of the heating means 4. As a result, as shown in FIG. 3, the base material 3 a is arranged so as to become the heating region A. In this state, the control means 6 stops the rotation of the deodorizing means 3.

その後、制御手段６は、加熱制御プログラムに基づいて、脱臭手段３の再生に要する温度に達するために必要な温度まで加熱手段４を昇温させる。この際、目的とする温度に達したか否かは、温度検出手段（図示せず）の検出結果で判定してもよいし、予め設計した加熱手段４の昇温プログラム（Δ℃／ｍｉｎ×ｍｉｎ）に基づいた加熱時間で判定してもよい。 Thereafter, the control means 6 raises the temperature of the heating means 4 to a temperature required to reach the temperature required for regeneration of the deodorizing means 3 based on the heating control program. At this time, whether or not the target temperature has been reached may be determined by a detection result of a temperature detection means (not shown), or a temperature increase program (Δ ° C./min× You may determine by the heating time based on min).

その後、脱臭手段３が目的とする温度まで昇温すると、制御手段６は、加熱手段４に所定時間加熱を継続させる。この際、加熱温度と加熱時間とは、脱臭手段３に吸着した臭気物質を除去するのに充分な温度と時間とに設定される。 Thereafter, when the deodorizing means 3 raises the temperature to the target temperature, the control means 6 causes the heating means 4 to continue heating for a predetermined time. At this time, the heating temperature and the heating time are set to a temperature and time sufficient to remove the odorous substance adsorbed on the deodorizing means 3.

このとき、断熱材５は、加熱手段４から加熱空間以外への放熱を抑制する。このため、加熱領域Ａの保温効果が高まる。その結果、脱臭手段３を目的とする温度にするための電力の消費量が抑制される。 At this time, the heat insulating material 5 suppresses heat radiation from the heating means 4 to other than the heating space. For this reason, the heat retention effect of the heating area | region A increases. As a result, the amount of electric power consumed to bring the deodorizing means 3 to the target temperature is suppressed.

加熱領域Ａの熱は、加熱手段４と対向しない非加熱領域Ｂの基材３ａに伝導しようとする。しかしながら、加熱手段４と対向する基材３ａの両側には、基材３ｂが配される。このため、当該熱の伝導は、当該加熱領域Ａの基材３ａ及び基材３ｂに限定される。 The heat in the heating area A tends to be conducted to the base material 3 a in the non-heating area B that does not face the heating means 4. However, the base material 3b is disposed on both sides of the base material 3a facing the heating means 4. For this reason, the conduction of the heat is limited to the base material 3a and the base material 3b in the heating region A.

加熱制御プログラムによる動作が完了すると、制御手段６は、加熱領域Ａの基材３ａに隣接する一方の別の基材３ａの全面が加熱手段４と対向するように、脱臭手段３を所定角度回転させる。 When the operation according to the heating control program is completed, the control means 6 rotates the deodorizing means 3 by a predetermined angle so that the entire surface of the other base material 3a adjacent to the base material 3a in the heating area A faces the heating means 4. Let

上記動作は、脱臭手段３の吸着性能の大きさや添着した触媒の種類等、種々の条件に基づいて決定される。例えば、脱臭手段３の臭気物質吸着容量を超える前に、脱臭手段３の全面が再生される。 The above operation is determined based on various conditions such as the size of the adsorption performance of the deodorizing means 3 and the kind of the attached catalyst. For example, before the odor substance adsorption capacity of the deodorizing means 3 is exceeded, the entire surface of the deodorizing means 3 is regenerated.

以上で説明した実施の形態１によれば、脱臭手段３は、熱伝導率の高い基材３ａと熱伝導率の低い基材３ｂとからなる。この際、基材３ａは、加熱手段４の上流側に配される。基材３ｂは、基材３ａの上流側に配される。このため、基材３ａに対する臭気物質の付着量は、基材３ｂに対する臭気物質の付着量よりも少ない。 According to Embodiment 1 demonstrated above, the deodorizing means 3 consists of the base material 3a with high heat conductivity, and the base material 3b with low heat conductivity. At this time, the base material 3 a is arranged on the upstream side of the heating means 4. The base material 3b is disposed on the upstream side of the base material 3a. For this reason, the adhesion amount of the odorous substance with respect to the base material 3a is smaller than the adhesion amount of the odorous substance with respect to the base material 3b.

図５には本脱臭装置の構成において、加熱手段４の昇温を開始してから触媒が臭気物質を酸化分解するのに必要な温度に昇温するまでに要する時間の差異をグラフで示した。これに因れば、加熱手段４と対向している熱伝導率の高い基材３ａは、加熱手段４が昇温を開始すると加熱手段４と対向している熱伝導率の高い基材３ａの間にある空気層を介して加熱手段４からの熱が伝えられ、加熱手段４とほぼ同等の昇温曲線を描く。
一方、基材３ａに比べて熱伝導率の低く、加熱手段４と対向する基材３ａの上流に接触して連続して配される基材３ｂは、加熱手段４が昇温を開始すると加熱手段４の熱が対向する空気層及び基材３ａを介して伝えられる。ただし、基材３ｂは基材３ａより熱伝導率が低いことから、加熱手段４の昇温開始直後の昇温の仕方は基材３ａより傾きが小さいという昇温曲線であり、触媒の酸化分解反応に必要な温度に到達するまでの時間も長く要する。 FIG. 5 is a graph showing the difference in time required for the catalyst to rise to a temperature necessary for oxidative decomposition of the odorous substance after the heating means 4 starts to rise in the configuration of the deodorizing apparatus. . According to this, the base material 3a having a high thermal conductivity facing the heating means 4 is not the base material 3a having the high thermal conductivity facing the heating means 4 when the heating means 4 starts to raise the temperature. Heat from the heating means 4 is transmitted through the air layer between them, and a temperature rise curve substantially equivalent to that of the heating means 4 is drawn.
On the other hand, the base material 3b, which has a lower thermal conductivity than the base material 3a and is continuously arranged in contact with the upstream side of the base material 3a facing the heating means 4, is heated when the heating means 4 starts to heat up. The heat of the means 4 is transferred through the opposing air layer and the substrate 3a. However, since the base material 3b has a lower thermal conductivity than the base material 3a, the heating method immediately after the start of the heating of the heating means 4 is a temperature rising curve in which the inclination is smaller than that of the base material 3a. It takes a long time to reach the temperature required for the reaction.

すなわち、基材３ａは短時間で触媒が酸化分解反応を生じるのに必要な温度に加熱される一方、基材３ｂは基材３ａに比べて熱伝導率が低いため、同じ温度に昇温するまでにより長い時間を要する。その一方で、加熱手段４の加熱が停止すると、基材３ａ単体では短時間で温度が低下するが、基材３ｂ単体では基材３ａに比べて温度の低下も緩やかに進行する。本脱臭装置の構成においては、基材３ｂからの余熱で基材３ａが温められるため、再生温度を一定に保つために加熱手段４を動作、あるいは停止を繰り返して温調する際にも、加熱手段４の加熱動作停止時の基材３ａの急激な温度低下を抑制することができる。 That is, while the base material 3a is heated to a temperature necessary for the catalyst to undergo an oxidative decomposition reaction in a short time, the base material 3b has a lower thermal conductivity than the base material 3a, and thus the temperature is raised to the same temperature. It takes longer time. On the other hand, when the heating of the heating means 4 is stopped, the temperature of the base material 3a alone is lowered in a short time, but the temperature of the base material 3b alone is gradually lowered as compared with the base material 3a. In the configuration of the deodorizing apparatus, since the base material 3a is warmed by the residual heat from the base material 3b, the heating means 4 is operated in order to keep the regeneration temperature constant, or when the temperature is controlled by repeatedly stopping the heating, It is possible to suppress a rapid temperature drop of the base material 3a when the heating operation of the means 4 is stopped.

基材３ａと基材３ｂとは、接触して連続して配される。このため、加熱手段４と基材３ａの間に空間があっても、基材３ａは加熱手段４と同等の温度にまで短時間で加熱され、当該熱が加熱領域Ａの基材３ａの全面から加熱領域Ａ内で断熱材５に囲われた基材３ｂに直接伝導される。当該伝導により、基材３ｂも効率よく均一に加熱される。その結果、脱臭手段３を効率的に再生することができる。 The base material 3a and the base material 3b are continuously arranged in contact with each other. For this reason, even if there is a space between the heating means 4 and the base material 3a, the base material 3a is heated to a temperature equivalent to that of the heating means 4 in a short time, and the heat is applied to the entire surface of the base material 3a in the heating region A. To the base material 3b surrounded by the heat insulating material 5 in the heating region A. The base material 3b is also efficiently and uniformly heated by the conduction. As a result, the deodorizing means 3 can be efficiently regenerated.

すなわち、基材３ｂにおいて触媒が作用する温度まで加熱されるのに時間を要し、脱臭した臭気物質が再放出された場合においても、基材３ａにおいては短時間で触媒が作用する温度まで加熱される。このため、再放出された臭気物質は、酸化分解される。その結果、脱臭性能回復動作時に脱臭手段３から臭気物質が再放出されることを抑制することができる。 That is, it takes time to heat the substrate 3b to the temperature at which the catalyst acts, and even when the deodorized odor substance is re-released, the substrate 3a is heated to the temperature at which the catalyst acts in a short time. Is done. For this reason, the re-released odor substance is oxidatively decomposed. As a result, it is possible to prevent the odorous substance from being released again from the deodorizing means 3 during the deodorizing performance recovery operation.

また、基材３ａは、基材３ｂに仕切られる。このため、加熱領域Ａ内の基材３ａから非加熱領域Ｂ内の基材３ａに熱が伝導することを抑制できる。その結果、電力の消費を抑制することができる。 Moreover, the base material 3a is partitioned by the base material 3b. For this reason, it can suppress that a heat | fever conducts from the base material 3a in the heating area | region A to the base material 3a in the non-heating area | region B. FIG. As a result, power consumption can be suppressed.

この際、吹出口１ｂの温度の上昇も抑制される。すなわち、脱臭動作と加熱手段４と対向する脱臭手段３の再生動作とを同時に行っても、脱臭手段３及び加熱手段４が断熱されているため、加熱手段４から加熱領域Ａに伝導した熱が非加熱領域Ｂに伝導して放熱することにより、吹出口１ｂから吹き出される空気が高温になることを抑制できる。このため、ユーザーの利便性が向上する。 At this time, an increase in the temperature of the outlet 1b is also suppressed. That is, even if the deodorizing operation and the regenerating operation of the deodorizing means 3 opposite to the heating means 4 are performed simultaneously, the heat transmitted from the heating means 4 to the heating area A is generated because the deodorizing means 3 and the heating means 4 are insulated. By conducting heat to the non-heated region B and dissipating heat, it is possible to prevent the air blown from the outlet 1b from becoming high temperature. For this reason, user convenience is improved.

また、加熱手段４が基材３ａに対向した際、当該基材３ａの全面が加熱手段４に対向する。このため、より短時間で加熱手段４と対向する脱臭手段３を再生することができる。 Further, when the heating means 4 faces the base material 3 a, the entire surface of the base material 3 a faces the heating means 4. For this reason, the deodorizing means 3 facing the heating means 4 can be regenerated in a shorter time.

また、基材３ａは、金属等からなる。基材３ｂは、セラミックやゼオライト等からなる。金属の熱伝導率は、セラミックやゼオライト等の熱伝導率よりも高い。このため、加熱領域Ａの基材３ａの奥行き方向の温度分布を均一にすることができる。その結果、触媒による酸化分解効率が向上する。すなわち、脱臭性能再生効率が向上する。この場合、基材３ｂへも加熱手段４と同等の温度が直接伝導される。このため、脱臭性能再生効率がより向上する。 The base material 3a is made of metal or the like. The base material 3b is made of ceramic, zeolite, or the like. The thermal conductivity of metals is higher than that of ceramics and zeolites. For this reason, the temperature distribution in the depth direction of the base material 3a in the heating region A can be made uniform. As a result, the oxidative decomposition efficiency by the catalyst is improved. That is, the deodorization performance regeneration efficiency is improved. In this case, a temperature equivalent to that of the heating means 4 is directly conducted to the base material 3b. For this reason, the deodorizing performance regeneration efficiency is further improved.

また、ゼオライト等の表面積は、一般的に金属の表面積よりも広い。このため、ゼオライト等を基材３ｂとし、通風路Ｒにおける空気の流れの進行方向に対して、基材３ａの上流側に配すれば、臭気物質の再放出を抑制する点で効果がある。 Further, the surface area of zeolite or the like is generally larger than that of metal. For this reason, if zeolite or the like is used as the base material 3b and is arranged upstream of the base material 3a with respect to the direction of air flow in the ventilation path R, there is an effect in that the re-release of odorous substances is suppressed.

また、脱臭手段３には、触媒が添着される。脱臭手段３に吸着した臭気物質を酸化分解する際の有効温度は、触媒の種類毎に異なる。当該温度は、通常１５０℃以上の高温である。すなわち、当該温度と室温との差が大きい。しかしながら、本実施の形態１のように、加熱手段４と対向する脱臭手段３のうち、基材３ａが基材３ｂにより断熱されているため、加熱手段から伝導される熱が非加熱領域Ｂに漏れずに、加熱領域Ａに対して集中的に効率良く伝導することができる。それにより、吸着された臭気物質は、完全酸化によって水と二酸化炭素とに分解される。当該分解により、臭気物質の再放出が抑制される。当該抑制により、ユーザーの不快感を抑制することができる。 Further, a catalyst is attached to the deodorizing means 3. The effective temperature for oxidative decomposition of the odorous substance adsorbed on the deodorizing means 3 varies depending on the type of catalyst. The said temperature is high temperature normally 150 degreeC or more. That is, the difference between the temperature and room temperature is large. However, since the base material 3a is insulated by the base material 3b among the deodorizing means 3 facing the heating means 4 as in the first embodiment, the heat conducted from the heating means is transferred to the non-heating region B. It is possible to conduct efficiently and intensively to the heating region A without leaking. Thereby, the adsorbed odor substance is decomposed into water and carbon dioxide by complete oxidation. Owing to the decomposition, the re-release of odorous substances is suppressed. This suppression can suppress user discomfort.

また、基材３ｂがあることにより、加熱領域Ａにある基材３ａに加えた熱が、非加熱領域Ｂにある基材３ａに伝導しにくくなる。このため、非加熱領域Ｂにある基材３ａが加熱されることにより酸化分解されず脱離した物質による臭気の発生を抑制することができる。 Further, the presence of the base material 3b makes it difficult for the heat applied to the base material 3a in the heating area A to be conducted to the base material 3a in the non-heating area B. For this reason, generation | occurrence | production of the odor by the substance which was not oxidized but decomposed | disassembled by heating the base material 3a in the non-heating area | region B can be suppressed.

なお、基材種ごとに添着させる触媒種を変えることで、異なる温度帯に活性域をもつ触媒を用い、幅広い臭気物質の脱臭に対応することができる。例えば、酸化マンガンや酸化銅においては、２００℃前後に活性域がある。これに対し、白金においては、温度による活性域が広い。酸化マンガンや酸化銅は、糞尿臭に含まれるアンモニア等の脱臭及び酸化分解性能が高い。これに対し、白金は、高温で芳香族炭化水素化合物等を酸化分解できる。また、糞尿臭に対応する脱臭装置において、基材３ａを金属として酸化マンガンを、基材３ｂをセラミックやゼオライトとして酸化マンガン及び酸化銅を、触媒として添着してもよい。この場合、基材３ｂで確実に脱臭し、再生時の臭気物質の再放出を抑制することができる。 In addition, by changing the catalyst type to be added for each base material type, it is possible to deal with a wide range of deodorization of odorous substances using a catalyst having an active region in different temperature zones. For example, manganese oxide and copper oxide have an active region around 200 ° C. In contrast, platinum has a wide active region depending on temperature. Manganese oxide and copper oxide have high deodorizing and oxidative decomposition performance of ammonia and the like contained in manure odor. In contrast, platinum can oxidatively decompose aromatic hydrocarbon compounds and the like at high temperatures. Moreover, in the deodorizing apparatus corresponding to manure odor, manganese oxide may be attached using the base material 3a as a metal, and manganese oxide and copper oxide may be attached using the base material 3b as a ceramic or zeolite as a catalyst. In this case, it is possible to reliably deodorize the base material 3b and suppress the re-release of odorous substances during regeneration.

また、基材３ａ及び基材３ｂは、脱臭手段３に着脱自在に設けられる。このため、脱臭手段３の上流に塵埃除去手段がなければ、基材３ａ及び基材３ｂを取り外し、基材３ａ及び基材３ｂの表面に付着した塵埃を家庭用シンクやバケツを用いて水浸漬洗いすることができる。その結果、脱臭手段３の衛生性を保つことができる。 Moreover, the base material 3a and the base material 3b are provided in the deodorizing means 3 so that attachment or detachment is possible. Therefore, if there is no dust removing means upstream of the deodorizing means 3, the base material 3a and the base material 3b are removed, and the dust adhering to the surfaces of the base material 3a and the base material 3b is immersed in water using a household sink or bucket. Can be washed. As a result, the sanitation of the deodorizing means 3 can be maintained.

また、基材３ａは、仕切りとなる基材３ｂとともに段にならずに均一に同一平面上に並ぶように円形状に形成される。この場合、脱臭手段３に本体ケース１の内面が近接している場合でも、脱臭手段３を回転させることができる。このため、脱臭装置の外寸を可能な限り小さくすることができる。また、送風手段２による風が脱臭手段３の全面に対して平面方向で均一に流れる。このため、臭気物質も均一に脱臭手段３に吸着する。このため、脱臭手段３の吸着有効面積を有効に活用できる。 Moreover, the base material 3a is formed in a circular shape so as to be uniformly arranged on the same plane without being stepped together with the base material 3b serving as a partition. In this case, even when the inner surface of the main body case 1 is close to the deodorizing means 3, the deodorizing means 3 can be rotated. For this reason, the outer dimension of a deodorizing apparatus can be made as small as possible. Moreover, the wind by the ventilation means 2 flows uniformly with respect to the whole surface of the deodorizing means 3 in a plane direction. For this reason, odorous substances are also adsorbed uniformly on the deodorizing means 3. For this reason, the adsorption effective area of the deodorizing means 3 can be utilized effectively.

また、加熱手段４は、脱臭手段３の下流側に設けられる。このため、吸入口１ａ側から脱臭装置内部の塵埃除去手段（図示せず）等を取り替える際にユーザーが加熱手段４に触れることを防止できる。 The heating unit 4 is provided on the downstream side of the deodorizing unit 3. For this reason, it is possible to prevent the user from touching the heating means 4 when replacing the dust removing means (not shown) in the deodorizing apparatus from the suction port 1a side.

なお、加熱手段４が脱臭手段３の上流側、または、上流側と下流側との双方に設けられる場合もある。この場合、加熱領域Ａを短時間で昇温することができる。すなわち、ユーザーが１回あたりの再生動作を待つ時間を短縮することができる。 The heating means 4 may be provided on the upstream side of the deodorizing means 3 or on both the upstream side and the downstream side. In this case, the heating area A can be heated in a short time. That is, it is possible to shorten the time for which the user waits for a reproduction operation per time.

また、脱臭手段３には、モータ等の駆動手段（図示せず）が取り付けられる。このため、図３に示すように、脱臭手段３に対して加熱手段４が一部分のみに対向する場合にも、脱臭手段３を効率的に再生することができる。 The deodorizing means 3 is attached with driving means (not shown) such as a motor. For this reason, as shown in FIG. 3, even when the heating means 4 faces only a part of the deodorizing means 3, the deodorizing means 3 can be efficiently regenerated.

また、制御手段６により、加熱手段４と脱臭手段３の相対位置が制御される。具体的には、各基材３ａの両側の基材３ｂが加熱手段４の両縁部の内側に配置されるように、脱臭手段３が停止する。このため、脱臭手段３の再生動作において、非加熱領域Ｂへの放熱を抑制することができる。 Further, the relative position of the heating means 4 and the deodorizing means 3 is controlled by the control means 6. Specifically, the deodorizing means 3 stops so that the base materials 3b on both sides of each base material 3a are arranged inside both edges of the heating means 4. For this reason, in the reproduction | regeneration operation | movement of the deodorizing means 3, the thermal radiation to the non-heating area | region B can be suppressed.

なお、図２〜４においては、基材３ａは基材３ｂによって仕切られる。加熱領域Ａは、脱臭手段３の４分の１の領域となる。しかしながら、この割合は、脱臭装置の使用環境や要求仕様により自由に設定してよい。加熱手段４が通気可能な構成で脱臭手段３の全面と対向する場合には、臭気物質の多い環境にも対応することができる。 2 to 4, the base material 3 a is partitioned by the base material 3 b. The heating area A is a quarter area of the deodorizing means 3. However, this ratio may be freely set according to the use environment and required specifications of the deodorizing apparatus. When the heating unit 4 is configured to be ventilated and faces the entire surface of the deodorizing unit 3, it can cope with an environment with a lot of odorous substances.

実施の形態２．
図６はこの発明の実施の形態２における脱臭装置の縦断面図である。なお、実施の形態１と同一又は相当部分には同一符号を付して説明を省略する。 Embodiment 2. FIG.
FIG. 6 is a longitudinal sectional view of a deodorizing apparatus according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and description is abbreviate | omitted.

実施の形態２の基材３ｂは、各基材３ａを仕切るとともに、脱臭手段３の外周部を囲う。空気の流れ方向に対する基材３ａ及び基材３ｂの配置は実施の形態１と同様である。実施の形態２は断熱材が配されない形態である。
上記脱臭手段３の一面及び他面が切り替わる境界は、図６においては円柱体である脱臭手段３の高さ方向にあたる辺の中央部として図示しているが、脱臭対象とする臭気物質や使用する触媒の種類や、基材３ａ及び３ｂの基材強度などを鑑みて決定してもよい。 The base material 3b of Embodiment 2 partitions each base material 3a and surrounds the outer peripheral portion of the deodorizing means 3. The arrangement of the base material 3a and the base material 3b with respect to the air flow direction is the same as in the first embodiment. Embodiment 2 is a form in which a heat insulating material is not arranged.
The boundary at which one side and the other side of the deodorizing means 3 are switched is shown in FIG. 6 as the central part of the side corresponding to the height direction of the deodorizing means 3 that is a cylindrical body. You may determine in consideration of the kind of catalyst, the base material strength of the base materials 3a and 3b, etc.

実施の形態２の脱臭装置の動作を説明する。なお、基本的には脱臭運転時の動作及び脱臭性能回復時の動作ともに実施の形態１の脱臭装置と同様に動作するため同様の説明を省略する。ここでは、脱臭性能回復動作について、一部重複する部分も含むが、加熱手段４から脱臭手段３への熱の伝わり方など実施の形態１と異なる配置としたことによる動作を主として説明する。 Operation | movement of the deodorizing apparatus of Embodiment 2 is demonstrated. In addition, since the operation | movement at the time of a deodorizing driving | operation and the operation | movement at the time of deodorizing performance recovery | restoration fundamentally operate | move like the deodorizing apparatus of Embodiment 1, the same description is abbreviate | omitted. Here, the deodorizing performance recovery operation includes a part that partially overlaps, but the operation by the arrangement different from that of the first embodiment, such as how heat is transmitted from the heating unit 4 to the deodorizing unit 3, will be mainly described.

脱臭手段再生動作において加熱手段４の加熱が開始されると、脱臭領域Ａにあたる基材３ａは空気層を介して昇温する。脱臭領域Ａにあたる基材３ａの熱は、基材３ａと直接接触して連続して配される基材３ｂの脱臭領域Ａに伝えられ、基材ｂが昇温する。この際、基材３ａを分割し、脱臭領域Ａと脱臭領域Ｂを仕切る役割を果たす基材３ｂ（図４図示の３ｂにあたる）にも基材３ａを介して加熱手段４の熱が伝熱するが、基材３ｂは基材３ａと比べて熱伝導率が低く、加熱手段４と対向していない部位に放熱しにくいため、脱臭手段３の外周部を囲う構成とすることで、基材３ａを周囲から断熱する作用を有する。
基材３ａ単体の場合には熱伝導率が高いため加熱手段４と対向していない部位にも熱が伝えられるために空気で冷却されて基材３ａが放熱して効率的に触媒の酸化分解反応に必要な温度に昇温することが難しい。一方、基材３ｂ単体では熱伝導率が基材３ａ比べて低いため、加熱手段４と対向していない部位にも熱が伝わりにくいため、基材３ａを周囲の空気環境から断熱することが可能となる。 When heating of the heating unit 4 is started in the deodorizing unit regeneration operation, the temperature of the base material 3a corresponding to the deodorizing region A is increased through the air layer. The heat of the base material 3a corresponding to the deodorizing region A is transmitted to the deodorizing region A of the base material 3b that is continuously arranged in direct contact with the base material 3a, and the base material b is heated. At this time, the heat of the heating means 4 is also transferred through the base material 3a to the base material 3b (corresponding to 3b shown in FIG. 4) which divides the base material 3a and separates the deodorization area A and the deodorization area B. However, since the base material 3b has a lower thermal conductivity than the base material 3a and is difficult to dissipate heat to a portion not facing the heating means 4, the base material 3a is configured to surround the outer periphery of the deodorizing means 3. It has the effect | action which insulates from surroundings.
In the case of the base material 3a alone, since the heat conductivity is high, the heat is transferred to the part not facing the heating means 4, so that it is cooled by air and the base material 3a dissipates heat to efficiently oxidize and decompose the catalyst. It is difficult to raise the temperature to the temperature required for the reaction. On the other hand, since the heat conductivity of the base material 3b alone is lower than that of the base material 3a, it is difficult for heat to be transmitted to a portion not facing the heating means 4, so that the base material 3a can be insulated from the surrounding air environment. It becomes.

以上で説明した実施の形態２によれば、断熱材５がなくても、実施の形態１と同様に脱臭手段３の再生率を有した状態で構成部材を減らすことができる。このため、脱臭装置を小型化することができる。 According to the second embodiment described above, even without the heat insulating material 5, the number of constituent members can be reduced in a state where the regeneration rate of the deodorizing means 3 is maintained as in the first embodiment. For this reason, a deodorizing apparatus can be reduced in size.

実施の形態３．
図７はこの発明の実施の形態３における脱臭装置の縦断面図である。なお、実施の形態１と同一又は相当部分には同一符号を付して説明を省略する。 Embodiment 3 FIG.
FIG. 7 is a longitudinal sectional view of a deodorizing apparatus according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and description is abbreviate | omitted.

実施の形態１及び２においては、基材３ａが通風路Ｒにおける空気の流れの進行方向に対して基材３ｂの下流側に配されていた。一方、実施の形態３においては、基材３ａが通風路Ｒにおける空気の流れの進行方向に対して基材３ｂの上流側に配される。また、加熱領域Ａ内の加熱手段４側において、基材３ａの一部が基材３ｂと同一平面を形成する。図７において、脱臭手段３の外周部の一部の基材３ａが基材３ｂと同一平面を形成する。また、脱臭領域Ａは断熱材５によりその周囲を覆われている。 In the first and second embodiments, the base material 3a is disposed on the downstream side of the base material 3b with respect to the traveling direction of the air flow in the ventilation path R. On the other hand, in Embodiment 3, the base material 3a is arranged on the upstream side of the base material 3b with respect to the traveling direction of the air flow in the ventilation path R. Further, on the heating means 4 side in the heating region A, a part of the base material 3a forms the same plane as the base material 3b. In FIG. 7, a part of the base material 3a on the outer periphery of the deodorizing means 3 forms the same plane as the base material 3b. The deodorizing area A is covered with a heat insulating material 5.

基材３ａ及び基材３ｂが同一平面を形成するということについて説明する。
加熱手段４と空気層を介して連続して配置される脱臭手段３の一面について、基材３ａは脱臭領域Ａと脱臭領域Ｂの境界にあたる部分を除いて脱臭手段３の外周部にあたり、脱臭手段３の外周部内側及び脱臭手段３の外周部の脱臭領域Ａと脱臭領域Ｂの境界にあたる部分は基材３ｂよりなる。
通風路Ｒの空気の流れ方向に対して吸込み口と空気層を介して（脱臭領域Ａは空気層及び断熱材５及び空気層を介して）連続して配置される脱臭手段３の他面について、基材３ｂは脱臭領域Ａと脱臭領域Ｂの境界にあたる部分であり基材３ａの熱が脱臭領域Ａ以外の部分に伝播して放熱することを抑制する仕切りの役割を果たす。基材３ｂは基材３ａと連続して接触するため、残りの扇状の部分は基材３ａより構成される。
上記脱臭手段３の一面及び他面が切り替わる境界は、図７においては円柱体である脱臭手段３の高さ方向にあたる辺の中央部として図示しているが、脱臭対象とする臭気物質や使用する触媒の種類や、基材３ａ及び３ｂの基材強度などを鑑みて決定してもよい。 The fact that the base material 3a and the base material 3b form the same plane will be described.
With respect to one surface of the deodorizing means 3 arranged continuously through the heating means 4 and the air layer, the base material 3a hits the outer periphery of the deodorizing means 3 except for the portion corresponding to the boundary between the deodorizing area A and the deodorizing area B. 3 and the portion corresponding to the boundary between the deodorizing region A and the deodorizing region B on the outer peripheral portion of the deodorizing means 3 are made of the base material 3b.
About the other side of the deodorizing means 3 arranged continuously with respect to the air flow direction of the ventilation path R through the suction port and the air layer (the deodorizing region A is through the air layer, the heat insulating material 5 and the air layer). The base material 3b is a portion corresponding to the boundary between the deodorizing area A and the deodorizing area B, and serves as a partition that suppresses the heat of the base material 3a from propagating to the part other than the deodorizing area A to dissipate heat. Since the base material 3b is in continuous contact with the base material 3a, the remaining fan-shaped portion is composed of the base material 3a.
The boundary at which one side and the other side of the deodorizing means 3 are switched is shown in FIG. 7 as the central portion of the side corresponding to the height direction of the deodorizing means 3 that is a cylindrical body. You may determine in consideration of the kind of catalyst, the base material strength of the base materials 3a and 3b, etc.

なお、図示されていないが、加熱領域Ａの端部においては、図４と同様、脱臭手段３の外周部全てが基材３ｂから構成されて加熱手段４の両縁部の内側に配される。 Although not shown, at the end of the heating area A, as in FIG. 4, the entire outer periphery of the deodorizing means 3 is composed of the base material 3 b and is arranged inside both edges of the heating means 4. .

実施の形態３の脱臭装置の動作を説明する。なお、基本的には脱臭運転時の動作及び脱臭性能回復時の動作ともに実施の形態１、及び２の脱臭装置と同様に動作するため同様の説明を省略する。ここでは、脱臭性能回復動作について、一部重複する部分も含むが、加熱手段４から脱臭手段３への熱の伝わり方など、実施の形態１及び２と異なる配置としたことによる動作を主として説明する。 Operation | movement of the deodorizing apparatus of Embodiment 3 is demonstrated. In addition, since the operation | movement at the time of a deodorizing driving | operation and the operation | movement at the time of deodorizing performance recovery | restoration operate | move similarly to Embodiment 1 and Embodiment 2, the same description is abbreviate | omitted. Here, the deodorizing performance recovery operation includes a part of which overlaps, but mainly the operation due to the arrangement different from the first and second embodiments, such as how heat is transferred from the heating means 4 to the deodorizing means 3. To do.

脱臭手段再生動作において加熱手段４の加熱が開始されると脱臭領域Ａの空気層を介して基材３ａ及び３ｂに伝熱して基材が昇温する。基材３ａは熱伝導率が高いため、加熱手段４と空気層を介して直接対向する部位は脱臭手段３の外周部（脱臭領域Ａと脱臭領域Ｂの境界は除く）のみであるが、基材３ｂの上流に接触して連続して配置されて脱臭領域Ａ全域にあたる部位も図５の昇温曲線の通りに昇温する。
基材３ｂは加熱手段４と空気層を介して連続して対向配置されており、空気層を介して熱が伝わって昇温するほか、基材３ｂの上流に接触して連続配置する基材３ａからの熱が伝わって昇温するため、脱臭領域Ａと脱臭領域Ｂの境界は除く基材３ｂの全周から熱が伝わる。 When heating of the heating means 4 is started in the deodorizing means regeneration operation, heat is transferred to the base materials 3a and 3b through the air layer in the deodorizing area A, and the temperature of the base material rises. Since the base material 3a has high thermal conductivity, the portion directly facing the heating means 4 through the air layer is only the outer peripheral portion of the deodorizing means 3 (except for the boundary between the deodorizing area A and the deodorizing area B). The part which is continuously arranged in contact with the upstream of the material 3b and corresponds to the entire region of the deodorization region A also rises in temperature as shown in the temperature rise curve of FIG.
The base material 3b is continuously arranged opposite to the heating means 4 through the air layer, and heat is transmitted through the air layer to raise the temperature, and the base material 3b is continuously arranged in contact with the upstream of the base material 3b. Since the heat from 3a is transmitted and the temperature is increased, the heat is transmitted from the entire circumference of the base material 3b excluding the boundary between the deodorizing area A and the deodorizing area B.

以上で説明した実施の形態３によれば、加熱領域Ａにおいて、加熱領域Ａの端部を除く脱臭手段３の外周部及び通風路Ｒにおける空気の流れの進行方向に対して上流側において、基材３ａに基材３ｂが直接接する状態で覆われる。このため、基材３ｂが短時間で加熱される。その結果、脱臭手段３の再生率が向上する。 According to the third embodiment described above, in the heating region A, on the upstream side with respect to the traveling direction of the air flow in the outer peripheral portion of the deodorizing means 3 excluding the end portion of the heating region A and the ventilation path R, The base material 3b is covered with the material 3a in direct contact. For this reason, the base material 3b is heated in a short time. As a result, the regeneration rate of the deodorizing means 3 is improved.

実施の形態３では、特に基材３ｂの主材をセラミックやゼオライトとして酸化マンガン及び酸化銅を触媒として添着した基材を用いる場合、主材を金属した基材を用いる場合に比べて臭気物質の吸着容量が大きいため、通風路Ｒの気流方向に対して基材３ｂが最上流に配置される形態に対し、基材３ａの下流に配置することで脱臭性能回復動作時に臭気物質を酸化分解する際の触媒反応で生成する熱による過熱を抑制することができる。これによって、加熱手段４による温度調整がスムーズに行われる。 In the third embodiment, in particular, when a base material in which the main material of the base material 3b is ceramic or zeolite and manganese oxide and copper oxide are used as a catalyst is used, the odor substance is compared with a case where a base material in which the main material is metal is used. Since the adsorption capacity is large, the base material 3b is disposed at the most upstream with respect to the airflow direction of the ventilation path R. By disposing the base material 3b downstream of the base material 3a, the odor substance is oxidatively decomposed during the deodorizing performance recovery operation. It is possible to suppress overheating due to heat generated by the catalytic reaction. Thereby, the temperature adjustment by the heating means 4 is performed smoothly.

なお、基材３ｂと同一平面を形成する基材３ａの一部は、加熱領域Ａ内であればよい。 In addition, the part of the base material 3a which forms the same plane as the base material 3b may be in the heating region A.

実施の形態４．
図８はこの発明の実施の形態４における脱臭装置の縦断面図である。なお、実施の形態３と同一又は相当部分には同一符号を付して説明を省略する。 Embodiment 4 FIG.
FIG. 8 is a longitudinal sectional view of a deodorizing apparatus according to Embodiment 4 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 3, or an equivalent, and description is abbreviate | omitted.

実施の形態３においては、脱臭手段３の加熱領域Ａの端部を除く脱臭手段３の外周部及び通風路Ｒにおける空気の流れの進行方向に対して上流側に、基材３ａが配されていた。一方、実施の形態４においては、基材３ｂの下流側前面も覆うように、基材３ａが配される。また、脱臭領域Ａは断熱材５によりその周囲を覆われている。 In the third embodiment, the base material 3a is arranged on the upstream side with respect to the outer peripheral portion of the deodorizing means 3 excluding the end of the heating region A of the deodorizing means 3 and the air flow direction in the ventilation path R. It was. On the other hand, in Embodiment 4, the base material 3a is arranged so as to cover the downstream side front surface of the base material 3b. The deodorizing area A is covered with a heat insulating material 5.

なお、図示されていないが、加熱領域Ａの端部においては、図４と同様、基材３ｂが加熱手段４の両縁部の内側に配される。基材３ｂは、脱臭手段３の通風路Ｒにおける空気の流れの進行方向に対して上流側の面及び下流側の面からみた場合、双方とも十字状に分割したような状態となる。これは、実施の形態３の通風路Ｒにおける空気の流れの進行方向に対して上流側の面と同様である。 Although not shown, at the end of the heating area A, the base material 3b is disposed inside both edges of the heating means 4 as in FIG. When viewed from the upstream surface and the downstream surface with respect to the direction of air flow in the ventilation path R of the deodorizing means 3, the base material 3b is in a state where both are divided into a cross shape. This is the same as the surface on the upstream side with respect to the traveling direction of the air flow in the ventilation path R of the third embodiment.

上記脱臭手段３の一面及び他面が切り替わる境界は、図８においては円柱体である脱臭手段３の高さ方向にあたる辺の中央部として図示しているが、脱臭対象とする臭気物質や使用する触媒の種類や、基材３ａ及び３ｂの基材強度などを鑑みて決定してもよい。 The boundary at which one side and the other side of the deodorizing means 3 are switched is shown as a central portion of the side corresponding to the height direction of the deodorizing means 3 which is a cylindrical body in FIG. You may determine in consideration of the kind of catalyst, the base material strength of the base materials 3a and 3b, etc.

実施の形態４の脱臭装置の動作を説明する。なお、基本的には脱臭運転時の動作及び脱臭性能回復時の動作ともに実施の形態１の脱臭装置と同様に動作するため同様の説明を省略する。ここでは、脱臭性能回復動作について、一部重複する部分も含むが、加熱手段４から脱臭手段３への熱の伝わり方など実施の形態１と異なる配置としたことによる動作を主として説明する。 Operation | movement of the deodorizing apparatus of Embodiment 4 is demonstrated. In addition, since the operation | movement at the time of a deodorizing driving | operation and the operation | movement at the time of deodorizing performance recovery | restoration fundamentally operate | move like the deodorizing apparatus of Embodiment 1, the same description is abbreviate | omitted. Here, the deodorizing performance recovery operation includes a part that partially overlaps, but the operation by the arrangement different from that of the first embodiment, such as how heat is transmitted from the heating unit 4 to the deodorizing unit 3, will be mainly described.

脱臭手段再生動作において加熱手段４の加熱が開始されると、加熱手段４と空気層を介して連続して配置する脱臭流域Ａにあたる基材３ａに熱が伝わり、図５に示す昇温曲線と同様に昇温する。基材３ａは通風路Ｒにおける空気の流れの進行方向に対して上流側に熱を伝えながら下流側の面の全面にも熱を伝える一方、脱臭領域Ａにあたる基材３ｂにも伝熱してこれを昇温する。
基材３ｂは脱臭領域Ａと脱臭領域Ｂの境界は除いて接触して連続して配される基材３ａに周囲を囲まれているため、接触した部位から熱が伝えられる。 When heating of the heating means 4 is started in the deodorizing means regeneration operation, heat is transferred to the base material 3a corresponding to the deodorizing flow area A continuously arranged through the heating means 4 and the air layer, and the temperature rise curve shown in FIG. Similarly, the temperature is raised. The base material 3a transfers heat to the entire downstream surface while transferring heat to the upstream side with respect to the direction of air flow in the ventilation path R, while also transferring heat to the base material 3b corresponding to the deodorizing region A. Raise the temperature.
Since the base material 3b is surrounded by the base material 3a arranged in contact and continuously except for the boundary between the deodorizing area A and the deodorizing area B, heat is transmitted from the contacted part.

以上で説明した実施の形態４によれば、短時間で目的温度まで加熱することができる基材３ａが基材３ｂに対して通風路Ｒにおける空気の流れの進行方向に対して上流側及び下流側に配される。このため、脱臭手段３の再生率が向上する。また、基材３ｂは、加熱手段４から加熱空間を介して加熱されるよりも多方向から直接加熱手段４と同等の熱が伝えられる。このため、基材３ｂは、均一に短時間に加熱される。その結果、基材３ｂの温度は、触媒が作用する温度に短時間で到達することができる。 According to Embodiment 4 demonstrated above, the base material 3a which can be heated to target temperature for a short time is upstream and downstream with respect to the advancing direction of the air flow in the ventilation path R with respect to the base material 3b. Arranged on the side. For this reason, the regeneration rate of the deodorizing means 3 is improved. Moreover, the base material 3b is directly transmitted with heat equivalent to that of the heating unit 4 from multiple directions, rather than being heated from the heating unit 4 through the heating space. For this reason, the base material 3b is heated uniformly in a short time. As a result, the temperature of the substrate 3b can reach the temperature at which the catalyst acts in a short time.

実施の形態１〜４において、脱臭手段３の形状は、円形状に限られるものではない。すなわち、脱臭手段３の形状は、脱臭装置の設計事由に適宜決定される。 In Embodiment 1-4, the shape of the deodorizing means 3 is not restricted to circular shape. That is, the shape of the deodorizing means 3 is appropriately determined depending on the design reason of the deodorizing apparatus.

なお、実施の形態１〜４に記載の脱臭手段３の再生方法は、脱臭機能を有する空気清浄機や空調機器の他、水や生ゴミ処理時の脱臭を目的とした装置に適用することができる。 In addition, the reproduction | regenerating method of the deodorizing means 3 described in Embodiment 1-4 can be applied to the apparatus aiming at the deodorization at the time of water and garbage disposal other than the air cleaner and air-conditioning equipment which have a deodorizing function. it can.
