Description
本発明は、除加湿ロータに関する。 The present invention relates to a dehumidifying / humidifying rotor.
従来の除加湿ロータは、例えば、珪藻土を含浸させた帯状のコルゲート紙を円筒型に巻設したものがあった（例えば、特許文献１参照）。 As a conventional dehumidifying / humidifying rotor, for example, a belt-shaped corrugated paper impregnated with diatomaceous earth is wound in a cylindrical shape (for example, see Patent Document 1).
特許文献１記載の除加湿ロータは、製造に手間がかかるという欠点があった。即ち、帯状コルゲート紙を円筒形状に巻設して厚さ寸法の大きいロール体を製造する工程を必要とし、さらに、このロール体を小さめの厚さ寸法に切断する工程を必要とし、製造が非能率的であり、手間がかかっていた。また、通過するエアーが層流となり、エアーが水分吸着粉体（珪藻土）と十分に接触しないという問題がある。すなわち、除加湿の効率が悪いという欠点があった。さらに、製造時に帯状コルゲート紙を回転軸に巻設して製造するので、除加湿ロータに中心貫孔が形成され、その分、エアーを除加湿可能な範囲が小さくなるという欠点もあった。 The dehumidifying / humidifying rotor described in Patent Document 1 has a drawback that it takes time to manufacture. That is, a step of manufacturing a roll body having a large thickness by winding a belt-like corrugated paper into a cylindrical shape is required, and further, a step of cutting the roll body into a smaller thickness is required. It was efficient and time consuming. Further, there is a problem that the air passing therethrough becomes a laminar flow and the air does not sufficiently contact the moisture adsorbing powder (diatomaceous earth). That is, there was a drawback that the efficiency of dehumidification / humidification was poor. Further, since the belt-like corrugated paper is wound around the rotating shaft during manufacture, a central through hole is formed in the dehumidifying / humidifying rotor, and there is a disadvantage that the range in which air can be dehumidified is reduced accordingly.
そこで、本発明は、容易に製造することができる除加湿ロータを提供することを目的とする。また、通過するエアーが乱れた流れとなって、水分吸着粉体と十分に接触させることができ、除加湿の効率が良い除加湿ロータを提供することを目的とする。さらに、中心貫孔を省略して、エアーを除湿可能な範囲を増加させることも可能な除加湿ロータを提供することを目的とする。 Then, an object of this invention is to provide the dehumidification / humidification rotor which can be manufactured easily. It is another object of the present invention to provide a dehumidifying / humidifying rotor having a turbulent flow of air that can be sufficiently brought into contact with moisture-adsorbing powder and having high dehumidifying / humidifying efficiency. It is another object of the present invention to provide a dehumidifying / humidifying rotor that can increase the range in which air can be dehumidified by omitting the central through hole.
そこで、本発明に係る除加湿ロータは、全体形状が円盤状であって、多数の連通状気孔を有する発泡セラミックから成り、該発泡セラミックには水分吸着粉体が含有され、上記気孔の内面に上記水分吸着粉体が露出して、上記気孔を通過するエアーが露出した上記水分吸着粉体に接触するように構成したものである。
また、全体形状が円盤状であって、多数の連通状気孔を有する発泡セラミックから成り、上記気孔の内面に水分吸着粉体が被覆されて、上記気孔を通過するエアーが上記水分吸着粉体に接触するように構成したものである。
Therefore, the dehumidifying / humidifying rotor according to the present invention has a disk shape as a whole and is made of a foamed ceramic having a large number of continuous pores. The foamed ceramic contains moisture adsorbing powder, and is formed on the inner surface of the pores. The moisture adsorbing powder is exposed, and the air passing through the pores is configured to contact the exposed moisture adsorbing powder.
In addition, the overall shape is a disk shape, and it is made of a foamed ceramic having a large number of continuous pores. The moisture adsorbing powder is coated on the inner surface of the pores, and the air passing through the pores is applied to the moisture adsorbing powder. It is comprised so that it may contact.
本発明の除加湿ロータによれば、容易に製造することができる。また、通過するエアーが乱れた流れとなって、水分吸着粉体と十分に接触させることができ、除加湿の効率が良い。さらに、中心貫孔を省略して、エアーを除湿可能な範囲を増加させることが可能である。 According to the dehumidifying / humidifying rotor of the present invention, it can be easily manufactured. Further, the passing air becomes a turbulent flow and can be sufficiently brought into contact with the moisture adsorbing powder, so that the efficiency of dehumidification / humidification is good. Furthermore, it is possible to increase the range in which air can be dehumidified by omitting the central through hole.
以下、図示の実施の形態に基づいて本発明を詳説する。
図１は、本発明の第１の実施の形態を示し、この除加湿ロータは、デシカント式空調装置に使用されるものであって、デシカントロータとも呼ばれる。
図１に示すように、デシカント式空調装置10は、除加湿ロータ１をロータ軸心Ｌａ廻りに回転させつつ、ロータ軸心一方側Ｊから湿気（水分）を含んだ処理空気Ａを吸い込んで、除加湿ロータ１の一部を通過させて水分を吸着させ、ロータ軸心他方側Ｋからヒータ等の熱源Ｈによって加熱された熱風Ｆを、除加湿ロータ１の残部に通過させて吸着した水分を放出させ、軸心一方向側Ｊへ湿気を含んだ熱風Ｆを送るように構成している。除加湿ロータ１の回転速度は、１時間当たり20回以下であり、例えば、１時間当たり５〜６回である。
Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
FIG. 1 shows a first embodiment of the present invention, and this dehumidifying / humidifying rotor is used in a desiccant type air conditioner and is also called a desiccant rotor.
As shown in FIG. 1, the desiccant air conditioner 10 sucks in processing air A containing moisture (moisture) from one side J of the rotor axis while rotating the dehumidifying / humidifying rotor 1 around the rotor axis La, Moisture is adsorbed by passing a part of the dehumidifying / humidifying rotor 1 to adsorb moisture and passing hot air F heated by a heat source H such as a heater from the other side K of the rotor shaft to the remaining part of the dehumidifying / humidifying rotor 1. It is made to discharge | release and the hot air F containing moisture is sent to the axial center one direction side J. The rotational speed of the dehumidifying / humidifying rotor 1 is 20 times or less per hour, for example, 5 to 6 times per hour.
また、ロータ両端面１ａ，１ｂ側に夫々配設された除加湿ロータ１に摺接する起毛を有する仕切部材９と、図示省略の隔壁と、によって、処理空気Ａと熱風Ｆが混流しないように、処理空気用流路と熱風用流路に区分けしている。
つまり、除加湿ロータ１は、水分を吸着した部位が処理空気用流路から、回転によって、熱風用流路に移動し、吸着した水分が放出され、その後、回転によって、処理空気用流路に戻って、再び水分を吸着するといったサイクルを繰り返すものである。
そして、デシカント式空調装置10は、処理空気用流路及び熱風用流路の上流口及び下流口を、屋内側や屋外側へ切り換えることで、屋内の除湿や加湿が行なえる。
Further, the partition member 9 having raised portions that are in sliding contact with the dehumidifying / humidifying rotor 1 disposed on the rotor both end faces 1a and 1b, respectively, and a partition wall (not shown) so that the processing air A and the hot air F do not flow together. It is divided into a flow path for processing air and a flow path for hot air.
That is, in the dehumidifying / humidifying rotor 1, the portion that has adsorbed moisture moves from the processing air channel to the hot air channel by rotation and releases the adsorbed moisture, and then rotates to the processing air channel. The cycle of returning and adsorbing moisture again is repeated.
The desiccant air conditioner 10 can perform dehumidification and humidification indoors by switching the upstream port and the downstream port of the processing air channel and the hot air channel to the indoor side or the outdoor side.
図１及び図５（Ａ）に示すように、除加湿ロータ１は、全体形状が所定厚さ寸法の円盤状である。そして、図２に示すように、多数の連通状気孔（連通気孔、連続気孔と言う場合もある）２を有する発泡セラミック３から成る。気孔２は、例えば、断面に於て、１インチ平方当たり３個以上60個以下となるような大きさに設定する。下限値未満では、エアーが十分に気孔２の内面５（の後述の水分吸着粉体４）と接触しない。上限値を超えると、通気性が悪くなる（通過抵抗が過大となる）。さらに好ましくは、１インチ平方当たり４個以上33個以下となるような大きさに設定する。 As shown in FIG. 1 and FIG. 5 (A), the dehumidifying / humidifying rotor 1 has a disk shape with an overall shape of a predetermined thickness. As shown in FIG. 2, it consists of a ceramic foam 3 having a large number of continuous pores 2 (sometimes referred to as continuous pores or continuous pores). For example, the pores 2 are set to have a size of 3 or more and 60 or less per square inch in cross section. If it is less than the lower limit value, the air does not sufficiently come into contact with the inner surface 5 (the moisture adsorbing powder 4 described later) of the pores 2. If the upper limit is exceeded, the air permeability becomes poor (the passage resistance becomes excessive). More preferably, the size is set to 4 or more and 33 or less per square inch.
図３（Ａ）、及び、その要部拡大図である図３（Ｂ）に示すように、発泡セラミック３には水分吸着粉体４が含有され、気孔２の内面５に水分吸着粉体４が露出して、気孔２を通過するエアーが露出した水分吸着粉体４に接触するように構成される。水分吸着粉体４は、ゼオライト、シリカゲル、珪藻土等であり、さらに、潮解物質等を付加することも好ましい。 As shown in FIG. 3 (A) and FIG. 3 (B) which is an enlarged view of a main part thereof, the foam ceramic 3 contains the moisture adsorbing powder 4, and the moisture adsorbing powder 4 is formed on the inner surface 5 of the pore 2. Is exposed, and the air passing through the pores 2 is configured to contact the exposed moisture adsorbing powder 4. The moisture adsorbing powder 4 is zeolite, silica gel, diatomaceous earth or the like, and it is also preferable to add a deliquescent material or the like.
ところで、発泡成型された本発明の除加湿ロータ１に形成されている多数の上記連通状気孔２は、各々、大きさ（断面積）、形状が相違し、かつ、エアー通過方向に、断面積が激しく増減変化し、かつ、断面形状も大きく変化し、さらに、気孔２が分岐・合流を繰り返す等、極めて変化に富んでいる。従って、このような気孔２を通過するエアーは、流れの方向、速度が、刻々変化し、かつ、分岐・合流を繰り返す。このような流れを、本発明では、「乱れた流れ」と呼ぶ。 By the way, the large number of communicating pores 2 formed in the dehumidifying / humidifying rotor 1 of the present invention formed by foaming are different in size (cross-sectional area) and shape, and have a cross-sectional area in the air passage direction. However, the cross-sectional shape is greatly changed, and the pores 2 are repeatedly branched and merged. Therefore, the air passing through the pores 2 changes in the direction and speed of the flow and repeats branching / merging. Such a flow is called “turbulent flow” in the present invention.
図４は、第２の実施の形態を示す。気孔２の内面５に水分吸着粉体４が被覆（付着）されて、気孔２を通過するエアーが水分吸着粉体４に接触するように構成される。水分吸着粉体４が、気孔２の内面５のみに存在する場合、及び、発泡セラミック３内にも（浸入状に）存在する場合のいずれも含む。その他の構成は、第１の実施の形態と同様である。 FIG. 4 shows a second embodiment. The inner surface 5 of the pores 2 is coated (attached) with the moisture adsorbing powder 4 so that the air passing through the pores 2 comes into contact with the moisture adsorbing powder 4. This includes both the case where the moisture adsorbing powder 4 is present only on the inner surface 5 of the pores 2 and the case where the moisture adsorbing powder 4 is also present in the foamed ceramic 3 (in an infiltrated manner). Other configurations are the same as those of the first embodiment.
図５（Ｂ）は、（図５（Ａ）に代わる）他の実施例を示す。全体形状が中心部に回転軸挿通用の中心貫孔６を有する円盤状である。
図５（Ｃ）は、別の実施例を示す。中心角90°の扇型の発泡セラミック分割体７が４個（接着等で）連結されて、全体形状が、中心貫孔６（図５（Ｂ），図５（Ｄ）参照）を省略した円盤状とされる。全体形状の円盤の直径が、例えば１ｍ以上の大きな除加湿ロータ１を製造するのに好適である（発泡セラミック３の成型金型が小さくて済む）。
図５（Ｄ）は、さらに別の実施例を示す。中心角45°の切欠き部８を有する扇型状の発泡セラミック分割体７が８個連結されて、全体形状が、中心部に回転軸挿通用の中心貫孔６を有する円盤状とされる。全体形状の円盤の直径が、例えば２ｍ以上の大きな除加湿ロータ１を製造するのに好適である（発泡セラミックの成型金型が小さくて済む）。
FIG. 5B shows another embodiment (instead of FIG. 5A). The overall shape is a disk shape having a central through hole 6 for inserting a rotating shaft at the center.
FIG. 5C shows another embodiment. Four fan-shaped ceramic foams 7 having a central angle of 90 ° are connected (by bonding or the like), and the overall shape omits the central through-hole 6 (see FIGS. 5B and 5D). It is a disk shape. It is suitable for manufacturing a large dehumidifying / humidifying rotor 1 having an overall shape disk having a diameter of, for example, 1 m or more (the molding die of the foamed ceramic 3 may be small).
FIG. 5D shows still another embodiment. Eight fan-shaped foamed ceramic divided bodies 7 having a notch 8 having a central angle of 45 ° are connected to each other, so that the overall shape is a disk shape having a central through hole 6 for inserting a rotating shaft at the center. . It is suitable for manufacturing a large dehumidifying / humidifying rotor 1 having a disk shape of an overall shape of, for example, 2 m or more (a small mold for foamed ceramic is required).
次に、本発明の除加湿ロータの製法について説明する。
第１の実施の形態の除加湿ロータ１は、セラミック、水分吸着粉体４、発泡剤、等を混合したスラリーを、発泡させて、乾燥、焼成して製造する。このとき、成型金型が用いられる。
第２の実施の形態の除加湿ロータ１は、発泡セラミック３を製造した後、水分吸着粉体４を接着剤等と混合したものを含浸させて、発泡セラミック３に水分吸着粉体４を付着させる。
Next, the manufacturing method of the dehumidification / humidification rotor of this invention is demonstrated.
The dehumidifying / humidifying rotor 1 according to the first embodiment is manufactured by foaming, drying and firing a slurry in which ceramic, moisture adsorbing powder 4, foaming agent, and the like are mixed. At this time, a molding die is used.
In the dehumidifying / humidifying rotor 1 according to the second embodiment, after the foamed ceramic 3 is manufactured, the moisture adsorbing powder 4 is impregnated with a mixture of the moisture adsorbing powder 4 and an adhesive or the like, and the moisture adsorbing powder 4 is adhered to the foaming ceramic 3. Let
なお、本発明は、設計変更可能であって、例えば、図５（Ｃ），（Ｄ）では４分割、８分割であったが、これを、全体形状の２分割、３分割等とすることも自由である。なお、発泡セラミック分割体７，７を相互に連結する手段としては、前述の接着以外に、連結枠体や、連結金具を用いることも、好ましい。なお、すり減りを防止し、及び、仕切部材９（図１参照）の接触による粉落ちを防止する為に、除加湿ロータ１の表面にシリコン接着剤等を塗布することも望ましい。 The present invention can be changed in design. For example, in FIGS. 5 (C) and 5 (D), it is divided into 4 and 8 divisions. Is also free. In addition, it is also preferable to use a connection frame body and a connection metal fitting other than the above-mentioned adhesion as means for connecting the ceramic foam bodies 7 and 7 to each other. It is also desirable to apply a silicon adhesive or the like to the surface of the dehumidifying / humidifying rotor 1 in order to prevent abrasion and to prevent powder falling due to contact with the partition member 9 (see FIG. 1).
以上のように、本発明は、全体形状が円盤状であって、多数の連通状気孔２を有する発泡セラミック３から成り、該発泡セラミック３には水分吸着粉体４が含有され、上記気孔２の内面５に上記水分吸着粉体４が露出して、上記気孔２を通過するエアーが露出した上記水分吸着粉体４に接触するように構成したので、容易に（効率的に）製造することができる。また、通過するエアーが「乱れた流れ」となって、エアーを水分吸着粉体４と十分に接触させることができ、除加湿の効率（除湿効率及び加湿効率）が良い。さらに、中心貫孔６を省略して、外径が同じでもエアーを除湿可能な範囲（エアー通過断面積）を増加させることも可能である。また、長年の使用により、発泡セラミック３がすり減っても、内部の水分吸着粉体４が順次露出するので、除加湿効率が低下することを防止できる。 As described above, the present invention has a disk shape as a whole, and includes the foamed ceramic 3 having a large number of continuous pores 2. The foamed ceramic 3 contains the moisture-adsorbing powder 4, and the pores 2. Since the moisture adsorbing powder 4 is exposed on the inner surface 5 of the gas and the air passing through the pores 2 is in contact with the exposed moisture adsorbing powder 4, it can be manufactured easily (effectively). Can do. Further, the passing air becomes a “turbulent flow”, and the air can be sufficiently brought into contact with the moisture adsorbing powder 4, so that the efficiency of dehumidification / humidification (dehumidification efficiency and humidification efficiency) is good. Further, it is possible to omit the central through hole 6 and increase a range (air cross-sectional area) where air can be dehumidified even if the outer diameter is the same. In addition, even if the ceramic foam 3 is worn out over many years, the internal moisture adsorbing powder 4 is sequentially exposed, so that it is possible to prevent the dehumidifying / humidifying efficiency from being lowered.
また、全体形状が円盤状であって、多数の連通状気孔２を有する発泡セラミック３から成り、上記気孔２の内面５に水分吸着粉体４が被覆されて、上記気孔２を通過するエアーが上記水分吸着粉体４に接触するように構成したので、容易に（効率的に）製造することができる。また、通過するエアーが「乱れた流れ」となって、エアーを水分吸着粉体４と十分に接触させることができ、除加湿の効率（除湿効率及び加湿効率）が良い。さらに、中心貫孔６を省略して、外径が同じでもエアーを除湿可能な範囲（エアー通過断面積）を増加させることも可能である。 Further, the overall shape is a disk shape, which is made of a foamed ceramic 3 having a large number of continuous pores 2. The inner surface 5 of the pores 2 is covered with the moisture adsorbing powder 4, and the air passing through the pores 2 is formed. Since it comprised so that the said moisture adsorption powder 4 might be contacted, it can manufacture easily (effectively). Further, the passing air becomes a “turbulent flow”, and the air can be sufficiently brought into contact with the moisture adsorbing powder 4, so that the efficiency of dehumidification / humidification (dehumidification efficiency and humidification efficiency) is good. Further, it is possible to omit the central through hole 6 and increase a range (air cross-sectional area) where air can be dehumidified even if the outer diameter is the same.

As shown in FIG. 1, the desiccant air conditioner 10 sucks in processing air A containing moisture (moisture) from one side J of the rotor axis while rotating the dehumidifying / humidifying rotor 1 around the rotor axis La, Moisture is adsorbed by passing a part of the dehumidifying / humidifying rotor 1 to adsorb moisture and passing hot air F heated by a heat source H such as a heater from the other side K of the rotor shaft to the remaining part of the dehumidifying / humidifying rotor 1. It is made to discharge | release and the hot air F containing moisture is sent to the axial center one direction side J. The rotational speed of the dehumidifying / humidifying rotor 1 is 20 times or less per hour, for example, 5 to 6 times per hour.
また、ロータ両端面１ａ，１ｂ側に夫々配設された除加湿ロータ１に摺接する起毛を有する仕切部材９と、図示省略の隔壁と、によって、処理空気Ａと熱風Ｆが混流しないように、処理空気用流路と熱風用流路に区分けしている。
つまり、除加湿ロータ１は、水分を吸着した部位が処理空気用流路から、回転によって、熱風用流路に移動し、吸着した水分が放出され、その後、回転によって、処理空気用流路に戻って、再び水分を吸着するといったサイクルを繰り返すものである。
そして、デシカント式空調装置10は、処理空気用流路及び熱風用流路の上流口及び下流口を、屋内側や屋外側へ切り換えることで、屋内の除湿や加湿が行なえる。
Further, the partition member 9 having raised portions that are in sliding contact with the dehumidifying / humidifying rotor 1 disposed on the rotor both end faces 1a and 1b, respectively, and a partition wall (not shown) so that the processing air A and the hot air F do not flow together. It is divided into a flow path for processing air and a flow path for hot air.
That is, in the dehumidifying / humidifying rotor 1, the portion that has adsorbed moisture moves from the processing air channel to the hot air channel by rotation and releases the adsorbed moisture, and then rotates to the processing air channel. The cycle of returning and adsorbing moisture again is repeated.
The desiccant air conditioner 10 can perform dehumidification and humidification indoors by switching the upstream port and the downstream port of the processing air channel and the hot air channel to the indoor side or the outdoor side.
図１及び図５（Ａ）に示すように、除加湿ロータ１は、全体形状が所定厚さ寸法の円盤状である。そして、図２に示すように、多数の連通状気孔（連通気孔、連続気孔と言う場合もある）２を有する発泡セラミック３から成る。気孔２は、例えば、断面に於て、１インチ平方当たり３個以上60個以下となるような大きさに設定する。下限値未満では、エアーが十分に気孔２の内面５（の後述の水分吸着粉体４）と接触しない。上限値を超えると、通気性が悪くなる（通過抵抗が過大となる）。さらに好ましくは、１インチ平方当たり４個以上33個以下となるような大きさに設定する。 As shown in FIG. 1 and FIG. 5 (A), the dehumidifying / humidifying rotor 1 has a disk shape with an overall shape of a predetermined thickness. As shown in FIG. 2, it consists of a ceramic foam 3 having a large number of continuous pores 2 (sometimes referred to as continuous pores or continuous pores). For example, the pores 2 are set to have a size of 3 or more and 60 or less per square inch in cross section. If it is less than the lower limit value, the air does not sufficiently come into contact with the inner surface 5 (the moisture adsorbing powder 4 described later) of the pores 2. If the upper limit is exceeded, the air permeability becomes poor (the passage resistance becomes excessive). More preferably, the size is set to 4 or more and 33 or less per square inch.
図３（Ａ）、及び、その要部拡大図である図３（Ｂ）に示すように、発泡セラミック３には水分吸着粉体４が含有され、気孔２の内面５に水分吸着粉体４が露出して、気孔２を通過するエアーが露出した水分吸着粉体４に接触するように構成される。水分吸着粉体４は、ゼオライト、シリカゲル、珪藻土等であり、さらに、潮解物質等を付加することも好ましい。 As shown in FIG. 3 (A) and FIG. 3 (B) which is an enlarged view of a main part thereof, the foam ceramic 3 contains the moisture adsorbing powder 4, and the moisture adsorbing powder 4 is formed on the inner surface 5 of the pore 2. Is exposed, and the air passing through the pores 2 is configured to contact the exposed moisture adsorbing powder 4. The moisture adsorbing powder 4 is zeolite, silica gel, diatomaceous earth or the like, and it is also preferable to add a deliquescent material or the like.
ところで、発泡成型された本発明の除加湿ロータ１に形成されている多数の上記連通状気孔２は、各々、大きさ（断面積）、形状が相違し、かつ、エアー通過方向に、断面積が激しく増減変化し、かつ、断面形状も大きく変化し、さらに、気孔２が分岐・合流を繰り返す等、極めて変化に富んでいる。従って、このような気孔２を通過するエアーは、流れの方向、速度が、刻々変化し、かつ、分岐・合流を繰り返す。このような流れを、本発明では、「乱れた流れ」と呼ぶ。 By the way, the large number of communicating pores 2 formed in the dehumidifying / humidifying rotor 1 of the present invention formed by foaming are different in size (cross-sectional area) and shape, and have a cross-sectional area in the air passage direction. However, the cross-sectional shape is greatly changed, and the pores 2 are repeatedly branched and merged. Therefore, the air passing through the pores 2 changes in the direction and speed of the flow and repeats branching / merging. Such a flow is called “turbulent flow” in the present invention.
図４は、第２の実施の形態を示す。気孔２の内面５に水分吸着粉体４が被覆（付着）されて、気孔２を通過するエアーが水分吸着粉体４に接触するように構成される。水分吸着粉体４が、気孔２の内面５のみに存在する場合、及び、発泡セラミック３内にも（浸入状に）存在する場合のいずれも含む。その他の構成は、第１の実施の形態と同様である。 FIG. 4 shows a second embodiment. The inner surface 5 of the pores 2 is coated (attached) with the moisture adsorbing powder 4 so that the air passing through the pores 2 comes into contact with the moisture adsorbing powder 4. This includes both the case where the moisture adsorbing powder 4 is present only on the inner surface 5 of the pores 2 and the case where the moisture adsorbing powder 4 is also present in the foamed ceramic 3 (in an infiltrated manner). Other configurations are the same as those of the first embodiment.
図５（Ｂ）は、（図５（Ａ）に代わる）他の実施例を示す。全体形状が中心部に回転軸挿通用の中心貫孔６を有する円盤状である。
図５（Ｃ）は、別の実施例を示す。中心角90°の扇型の発泡セラミック分割体７が４個（接着等で）連結されて、全体形状が、中心貫孔６（図５（Ｂ），図５（Ｄ）参照）を省略した円盤状とされる。全体形状の円盤の直径が、例えば１ｍ以上の大きな除加湿ロータ１を製造するのに好適である（発泡セラミック３の成型金型が小さくて済む）。
図５（Ｄ）は、さらに別の実施例を示す。中心角45°の切欠き部８を有する扇型状の発泡セラミック分割体７が８個連結されて、全体形状が、中心部に回転軸挿通用の中心貫孔６を有する円盤状とされる。全体形状の円盤の直径が、例えば２ｍ以上の大きな除加湿ロータ１を製造するのに好適である（発泡セラミックの成型金型が小さくて済む）。

FIG. 5C shows another embodiment. Four fan-shaped ceramic foams 7 having a central angle of 90 ° are connected (by bonding or the like), and the overall shape omits the central through-hole 6 (see FIGS. 5B and 5D). It is a disk shape. It is suitable for manufacturing a large dehumidifying / humidifying rotor 1 having an overall shape disk having a diameter of, for example, 1 m or more (the molding die of the foamed ceramic 3 may be small).
FIG. 5D shows still another embodiment. Eight fan-shaped foamed ceramic divided bodies 7 having a notch 8 having a central angle of 45 ° are connected to each other, so that the overall shape is a disk shape having a central through hole 6 for inserting a rotating shaft at the center. . It is suitable for manufacturing a large dehumidifying / humidifying rotor 1 having a disk shape of an overall shape of, for example, 2 m or more (a small mold for foamed ceramic is required).
次に、本発明の除加湿ロータの製法について説明する。
第１の実施の形態の除加湿ロータ１は、セラミック、水分吸着粉体４、発泡剤、等を混合したスラリーを、発泡させて、乾燥、焼成して製造する。このとき、成型金型が用いられる。
第２の実施の形態の除加湿ロータ１は、発泡セラミック３を製造した後、水分吸着粉体４を接着剤等と混合したものを含浸させて、発泡セラミック３に水分吸着粉体４を付着させる。
Next, the manufacturing method of the dehumidification / humidification rotor of this invention is demonstrated.
The dehumidifying / humidifying rotor 1 according to the first embodiment is manufactured by foaming, drying and firing a slurry in which ceramic, moisture adsorbing powder 4, foaming agent, and the like are mixed. At this time, a molding die is used.
In the dehumidifying / humidifying rotor 1 according to the second embodiment, after the foamed ceramic 3 is manufactured, the moisture adsorbing powder 4 is impregnated with a mixture of the moisture adsorbing powder 4 and an adhesive or the like, and the moisture adsorbing powder 4 is adhered to the foaming ceramic 3. Let
なお、本発明は、設計変更可能であって、例えば、図５（Ｃ），（Ｄ）では４分割、８分割であったが、これを、全体形状の２分割、３分割等とすることも自由である。なお、発泡セラミック分割体７，７を相互に連結する手段としては、前述の接着以外に、連結枠体や、連結金具を用いることも、好ましい。なお、すり減りを防止し、及び、仕切部材９（図１参照）の接触による粉落ちを防止する為に、除加湿ロータ１の表面にシリコン接着剤等を塗布することも望ましい。 The present invention can be changed in design. For example, in FIGS. 5 (C) and 5 (D), it is divided into 4 and 8 divisions. Is also free. In addition, it is also preferable to use a connection frame body and a connection metal fitting other than the above-mentioned adhesion as means for connecting the ceramic foam bodies 7 and 7 to each other. It is also desirable to apply a silicon adhesive or the like to the surface of the dehumidifying / humidifying rotor 1 in order to prevent abrasion and to prevent powder falling due to contact with the partition member 9 (see FIG. 1).
以上のように、本発明は、全体形状が円盤状であって、多数の連通状気孔２を有する発泡セラミック３から成り、該発泡セラミック３には水分吸着粉体４が含有され、上記気孔２の内面５に上記水分吸着粉体４が露出して、上記気孔２を通過するエアーが露出した上記水分吸着粉体４に接触するように構成したので、容易に（効率的に）製造することができる。また、通過するエアーが「乱れた流れ」となって、エアーを水分吸着粉体４と十分に接触させることができ、除加湿の効率（除湿効率及び加湿効率）が良い。さらに、中心貫孔６を省略して、外径が同じでもエアーを除湿可能な範囲（エアー通過断面積）を増加させることも可能である。また、長年の使用により、発泡セラミック３がすり減っても、内部の水分吸着粉体４が順次露出するので、除加湿効率が低下することを防止できる。 As described above, the present invention has a disk shape as a whole, and includes the foamed ceramic 3 having a large number of continuous pores 2. The foamed ceramic 3 contains the moisture-adsorbing powder 4, and the pores 2. Since the moisture adsorbing powder 4 is exposed on the inner surface 5 of the gas and the air passing through the pores 2 is in contact with the exposed moisture adsorbing powder 4, it can be manufactured easily (effectively). Can do. Further, the passing air becomes a “turbulent flow”, and the air can be sufficiently brought into contact with the moisture adsorbing powder 4, so that the efficiency of dehumidification / humidification (dehumidification efficiency and humidification efficiency) is good. Further, it is possible to omit the central through hole 6 and increase a range (air cross-sectional area) where air can be dehumidified even if the outer diameter is the same. In addition, even if the ceramic foam 3 is worn out over many years, the internal moisture adsorbing powder 4 is sequentially exposed, so that it is possible to prevent the dehumidifying / humidifying efficiency from being lowered.
また、全体形状が円盤状であって、多数の連通状気孔２を有する発泡セラミック３から成り、上記気孔２の内面５に水分吸着粉体４が被覆されて、上記気孔２を通過するエアーが上記水分吸着粉体４に接触するように構成したので、容易に（効率的に）製造することができる。また、通過するエアーが「乱れた流れ」となって、エアーを水分吸着粉体４と十分に接触させることができ、除加湿の効率（除湿効率及び加湿効率）が良い。さらに、中心貫孔６を省略して、外径が同じでもエアーを除湿可能な範囲（エアー通過断面積）を増加させることも可能である。 Further, the overall shape is a disk shape, which is made of a foamed ceramic 3 having a large number of continuous pores 2. The inner surface 5 of the pores 2 is covered with the moisture adsorbing powder 4, and the air passing through the pores 2 is formed. Since it comprised so that the said moisture adsorption powder 4 might be contacted, it can manufacture easily (effectively). Further, the passing air becomes a “turbulent flow”, and the air can be sufficiently brought into contact with the moisture adsorbing powder 4, so that the efficiency of dehumidification / humidification (dehumidification efficiency and humidification efficiency) is good. Further, it is possible to omit the central through hole 6 and increase a range (air cross-sectional area) where air can be dehumidified even if the outer diameter is the same.
