Description

除加湿ユニットdehumidification unit
　本開示は、空気調和機等に用いられる除加湿ユニットに関する。 The present disclosure relates to a dehumidifying/humidifying unit used in air conditioners and the like.
　例えば、特許文献１には、加湿ユニットが備えるファン１０７が開示されている。図１１～図１３は、特許文献１におけるファン１０７の構成を示す斜視図、正面図及び側断面図である。ファン１０７は、吸着材（吸着脱離材）の吸着及び脱離のための空気を吸着材へ供給する。 For example, Patent Document 1 discloses a fan 107 included in a humidification unit. 11 to 13 are a perspective view, a front view, and a side sectional view showing the configuration of the fan 107 in Patent Document 1. FIG. The fan 107 supplies air for adsorption and desorption of the adsorbent (adsorption/desorption material) to the adsorbent.
　図１１～図１３に示されるように、ファン１０７は、ファンロータ１７１と、ファンモータ１７２と、ファンケーシング１７３と、ディフューザ１７４と、ディフューザ駆動部１７５とを備える。 As shown in FIGS. 11 to 13, the fan 107 includes a fan rotor 171, a fan motor 172, a fan casing 173, a diffuser 174, and a diffuser driving section 175.
　ファンロータ１７１は、ファンモータ１７２の回転軸１７２ａに固定される。 The fan rotor 171 is fixed to the rotating shaft 172a of the fan motor 172.
　ファンロータ１７１は、リング状の主板１７１ａの内周縁部に多数のフィン１７１ｂが立設されたターボファン（具体的には、遠心及び斜流の複合ファン）である。 The fan rotor 171 is a turbo fan (specifically, a centrifugal and diagonal flow composite fan) in which a large number of fins 171b are erected on the inner peripheral edge of a ring-shaped main plate 171a.
　ファンケーシング１７３は、スクロール形状を有するスクロールケーシングであり、下面側にファン１０７の吸気口１０７ａが形成され、側部にファン１０７の排気口１０７ｂが形成されている。 The fan casing 173 is a scroll casing having a scroll shape, and has an intake port 107a of the fan 107 formed on the bottom side and an exhaust port 107b of the fan 107 formed on the side.
　また、ファンケーシング１７３の上面側には、ディフューザ１７４によって開閉される開口１０７ｃが形成されている。 Also, an opening 107c that is opened and closed by a diffuser 174 is formed on the upper surface side of the fan casing 173 .
　ディフューザ１７４は、ファンロータ１７１からの遠心方向への送風である吸着排気Ｆ３を許容する第１状態と、吸着排気Ｆ３を抑える第２状態とを切り換える切換部材である。ディフューザ１７４によって開閉される開口１０７ｃは、第１状態における遠心方向への空気流れである吸着排気Ｆ３の吹出口となっている。開口１０７ｃ近傍のファンケーシング１７３内側の空気流路は、ディフューザ１７４の内面とファンケーシング１７３の内面によって形成されている。従って、ディフューザ１７４は、第１状態における遠心方向への空気流れである吸着排気Ｆ３を所定の風量及び圧力に調整することが可能である。ディフューザ１７４は、ファンケーシング１７３の上面側の開口１０７ｃを覆うように設けられている。ディフューザ１７４は、ディフューザ駆動部１７５によって、ファンロータ１７１の遠心方向（吸着排気Ｆ３の向き）に対して交差する方向、例えば回転軸１７２ａの延びる方向Ｄ１に沿って往復移動することにより、開口１０７ｃを開閉することが可能である。これにより、ディフューザ１７４は、吸着材の吸着時において、上方へ移動して開口１０７ｃを開放させて第１状態に切り換える。これにより、ファン１０７が低静圧で大風量の空気を吸着材へ供給することを可能にする。一方、吸着材の脱離時において、ディフューザ１７４は、下方へ移動して開口１０７ｃを閉じて第２状態に切り換えることにより、ファン１０７が高静圧で小風量の空気を吸着材へ供給することを可能にする。 The diffuser 174 is a switching member that switches between a first state in which the sucked exhaust F3, which is air blown in the centrifugal direction from the fan rotor 171, is allowed and a second state in which the sucked exhaust F3 is suppressed. The opening 107c opened and closed by the diffuser 174 serves as an outlet for the suction exhaust F3, which is the air flow in the centrifugal direction in the first state. An air flow path inside the fan casing 173 near the opening 107 c is formed by the inner surface of the diffuser 174 and the inner surface of the fan casing 173 . Therefore, the diffuser 174 can adjust the suction exhaust F3, which is the air flow in the centrifugal direction in the first state, to a predetermined air volume and pressure. The diffuser 174 is provided so as to cover the opening 107c on the top side of the fan casing 173 . The diffuser drive unit 175 reciprocates the diffuser 174 in a direction intersecting the centrifugal direction of the fan rotor 171 (the direction of the suction exhaust F3), for example, along the direction D1 in which the rotating shaft 172a extends, thereby moving the opening 107c. It can be opened and closed. As a result, the diffuser 174 moves upward to open the opening 107c and switch to the first state when adsorbing the adsorbent. This enables the fan 107 to supply a large volume of air to the adsorbent at a low static pressure. On the other hand, when the adsorbent is desorbed, the diffuser 174 moves downward to close the opening 107c and switch to the second state so that the fan 107 supplies air of high static pressure and small air volume to the adsorbent. enable
　ディフューザ駆動部１７５は、図１３に示されるように、駆動用モータ１７７と、駆動用ギア１７８と、ギア受け部１７９とを有している。駆動用モータ１７７は、駆動用ギア１７８を回転駆動するステッピングモータである。駆動用ギア１７８は、丸棒状の形態を有しており、その表面におねじ１７８ａが形成されている。駆動用ギア１７８の下端部は、ファンケーシング１７３の中央固定部１８０に回転自在に支持されている。駆動用ギア１７８の上端部は、駆動用モータ１７７の駆動軸１７７ａと連結されている。ギア受け部１７９は、円筒状の形態を有しており、その内面に駆動用ギア１７８のおねじ１７８ａと螺合するめねじが形成されている。ギア受け部１７９は、ディフューザ１７４と一体に形成されている。 The diffuser driving portion 175 has a driving motor 177, a driving gear 178, and a gear receiving portion 179, as shown in FIG. The driving motor 177 is a stepping motor that rotationally drives the driving gear 178 . The drive gear 178 has a round bar shape, and a male thread 178a is formed on the surface thereof. A lower end portion of the drive gear 178 is rotatably supported by a central fixed portion 180 of the fan casing 173 . An upper end portion of the drive gear 178 is connected to a drive shaft 177 a of the drive motor 177 . The gear receiving portion 179 has a cylindrical shape, and has a female thread formed on its inner surface to be screwed with the male thread 178a of the driving gear 178 . The gear receiving portion 179 is formed integrally with the diffuser 174 .
　ディフューザ駆動部１７５では、駆動用モータ１７７が駆動用ギア１７８を正転または逆転させることにより、以下のことが可能になる。すなわち、ディフューザ駆動部１７５では、駆動用ギア１７８に螺合しているギア受け部１７９、及びギア受け部１７９と一体になっているディフューザ１７４を回転軸１７２ａの延びる方向Ｄ１に沿って往復移動させることが可能である。これによって、ディフューザ１７４は、上記の第１状態と第２状態とを切り換えることが可能である。 In the diffuser drive unit 175, the drive motor 177 rotates the drive gear 178 forward or backward, thereby enabling the following. That is, in the diffuser driving section 175, the gear receiving section 179 screwed to the driving gear 178 and the diffuser 174 integrated with the gear receiving section 179 are reciprocated along the direction D1 in which the rotating shaft 172a extends. It is possible. This allows the diffuser 174 to switch between the first state and the second state.
　また、ディフューザ１７４の周縁部には、ディフューザ１７４を閉めたときにディフューザ１７４とファンケーシング１７３との隙間から空気が洩れないように、発泡ゴムなどからなるシール材１７６が設けられている。 In addition, a sealing material 176 made of foam rubber or the like is provided on the periphery of the diffuser 174 so that air does not leak from the gap between the diffuser 174 and the fan casing 173 when the diffuser 174 is closed.
　ファン１０７は、吸着材の吸着時及び脱離時それぞれにおいて回転数が異なるようにファンロータ１７１が回転するように設定されている。 The fan 107 is set so that the fan rotor 171 rotates at different speeds when adsorbing and desorbing the adsorbent.

　なお、吸着脱離材５８は、空気中の水分を収着する高分子収着材で形成されることが好ましい。高分子収着材は、例えば、ポリアクリル酸ナトリウム架橋体から構成される。高分子収着材は、シリカゲルやゼオライトなどの吸着材に比べて、水分を吸収する速度が高く、低い加熱温度で保持する水分を脱離することができ、そして水分を長時間保持することができる。 It should be noted that the adsorption/desorption material 58 is preferably made of a polymer sorption material that sorbs moisture in the air. The polymeric sorbent material is composed of, for example, a crosslinked sodium polyacrylate. Compared to adsorbents such as silica gel and zeolite, polymer sorbents absorb moisture at a higher rate, can desorb retained moisture at low heating temperatures, and can retain moisture for a long time. can.
　除加湿ユニット５０はまた、図５に示すように、室外空気Ａｏｕｔを除加湿ユニット５０内に誘引して吸着脱離材５８を通過させ、吸着脱離材５８を通過した室外空気Ａｏｕｔを室内機２０に向かって送風するファン６６を備える。 The dehumidification/humidification unit 50 also induces the outdoor air Aout into the dehumidification/humidification unit 50 to pass through the adsorption/desorption material 58 as shown in FIG. A fan 66 blowing air toward 20 is provided.
　また、除加湿ユニット５０は、図４に示すように、ヒータ６７は、吸着脱離材５８の近傍に配置されている。ヒータ６７は、例えば、ＰＴＣヒータ（Ｐｏｓｉｔｉｖｅ　Ｔｅｍｐｅｒａｔｕｒｅ　Ｃｏｅｆｆｉｃｉｅｎｔ）であり、室外空気Ａｏｕｔの流れにおける吸着脱離材５８の上流側に設けられ、脱離のために室外空気Ａｏｕｔを加温する。なお、ヒータ６７は、ＰＴＣヒータに限られず、ニクロム線やカーボン繊維などを用いるヒータであってもよい。 Also, in the dehumidifying/humidifying unit 50, the heater 67 is arranged in the vicinity of the adsorption/desorption material 58, as shown in FIG. The heater 67 is, for example, a PTC heater (Positive Temperature Coefficient), is provided upstream of the adsorption/desorption material 58 in the flow of the outdoor air Aout, and heats the outdoor air Aout for desorption. Note that the heater 67 is not limited to the PTC heater, and may be a heater using a nichrome wire, carbon fiber, or the like.
　ファン６６は、吸着脱離材５８に対して除加湿ユニット５０の長手方向（Ｙ軸方向）の一方側に配置され、例えばシロッコファンである。ファン６６は、吸着脱離材５８に対して長手方向の一方側の空間を上下に二分割する隔壁板６８に設けられた円筒状部６８ａ内に収容されている。この隔壁板６８により、図５に示すように、吸着脱離材５８の上面５８ａの一部分が接する上側空間Ｓ１と、吸着脱離材５８の下面５８ｂの一部分が接する下側空間Ｓ２とが形成されている。 The fan 66 is arranged on one side in the longitudinal direction (Y-axis direction) of the dehumidifying/humidifying unit 50 with respect to the adsorption/desorption material 58, and is, for example, a sirocco fan. The fan 66 is accommodated in a cylindrical portion 68a provided in a partition plate 68 that vertically divides the space on one side of the adsorption/desorption material 58 in the longitudinal direction. As shown in FIG. 5, the partition plate 68 forms an upper space S1 with which a portion of the upper surface 58a of the adsorption/desorption material 58 is in contact and a lower space S2 with which a portion of the lower surface 58b of the adsorption/desorption material 58 is in contact. ing.
　隔壁板６８の円筒状部６８ａには、排気口５２ｄに接続する開口６８ｂと、排気口５２ｅと接続する開口６８ｃとが形成されている。また、隔壁板６８には、円筒状部６８ａ内のファン６６に空気を取り込むための貫通穴６８ｄが形成されている。 The cylindrical portion 68a of the partition plate 68 is formed with an opening 68b connected to the exhaust port 52d and an opening 68c connected to the exhaust port 52e. Further, the partition plate 68 is formed with a through hole 68d for taking air into the fan 66 in the cylindrical portion 68a.
　また、隔壁板６８の円筒状部６８ａには、ファン６６を覆うファンカバー７０が取り付けられている。そのファンカバー７０に、ファン６６を回転させるモータ７２が設けられている。また、ファンカバー７０には、隔壁板６８の開口６８ｂ及び開口６８ｃのうちの一方を閉じるダンパ装置７４が設けられている（図４参照）。詳細は後述するが、ダンパ装置７４は、旋回可能なダンパ７４ａを備え、そのダンパ７４ａを旋回させることによって隔壁板６８の開口６８ｂ及び開口６８ｃのうちの一方を閉じるように構成されている。 A fan cover 70 that covers the fan 66 is attached to the cylindrical portion 68 a of the partition plate 68 . A motor 72 for rotating the fan 66 is provided on the fan cover 70 . Further, the fan cover 70 is provided with a damper device 74 that closes one of the openings 68b and 68c of the partition plate 68 (see FIG. 4). Although details will be described later, the damper device 74 includes a turnable damper 74a and is configured to close one of the openings 68b and 68c of the partition plate 68 by turning the damper 74a.
　モータ７２がファン６６を回転させると、図４に示すように、筺体５２の吸気口５２ａ、５２ｂを介して、室外空気Ａｏｕｔが筺体５２内に流入する。具体的には、図５に示すように、吸気口５２ａ、５２ｂそれぞれを介して流入した室外空気Ａｏｕｔは、隔壁板６８の上方の上側空間Ｓ１に流入し、吸着脱離材５８の上方に向かって流れる。次に、室外空気Ａｏｕｔは、吸着脱離材５８の上面５８ａから下面５８ｂに向かって吸着脱離材５８を通過する。そして、吸着脱離材５８を通過した室外空気Ａｏｕｔは、隔壁板６８の下方の下側空間Ｓ２内を移動し、隔壁板６８の貫通穴６８ｄを通過してファン６６に取り込まれる。ファン６６に取り込まれた室外空気Ａｏｕｔは、開口６８ｂ及び開口６８ｃのうち、ダンパ装置７４のダンパ７４ａによって閉じられていない方の開口を通過する。すなわち、室外空気Ａｏｕｔは、排気口５２ｄを通過して最終的に室内機２０内に到達する、または排気口５２ｅを介して室外Ｒｏｕｔに排出される。図４及び図５に示すように、筺体５２の吸気口５２ａと吸気口５２ｂとの間には、ファンカバー７０とモータ７２とが存在する。そのため、吸着脱離材５８を通過し、室外Ｒｏｕｔと室内機２０内とを接続し、室外空気Ａｏｕｔが流れる流路が実質的に２つ存在する。 When the motor 72 rotates the fan 66, the outdoor air Aout flows into the housing 52 through the intake ports 52a and 52b of the housing 52, as shown in FIG. Specifically, as shown in FIG. 5, the outdoor air Aout that has flowed in through the air inlets 52a and 52b flows into the upper space S1 above the partition plate 68, and then flows upward from the adsorption/desorption material 58. flow. Next, the outdoor air Aout passes through the adsorption/desorption material 58 from the top surface 58a of the adsorption/desorption material 58 toward the bottom surface 58b. After passing through the adsorption/desorption material 58 , the outdoor air Aout moves in the lower space S<b>2 below the partition plate 68 , passes through the through holes 68 d of the partition plate 68 , and is taken into the fan 66 . The outdoor air Aout taken in by the fan 66 passes through the opening that is not closed by the damper 74a of the damper device 74, out of the opening 68b and the opening 68c. That is, the outdoor air Aout passes through the exhaust port 52d and finally reaches the inside of the indoor unit 20, or is discharged to the outdoor Rout through the exhaust port 52e. As shown in FIGS. 4 and 5, a fan cover 70 and a motor 72 are present between the intake ports 52a and 52b of the housing 52. As shown in FIGS. Therefore, there are substantially two flow paths that pass through the adsorption/desorption material 58, connect the outdoor Rout and the interior of the indoor unit 20, and allow the outdoor air Aout to flow.
　以下、ダンパ装置７４における室外空気Ａｏｕｔの流れを、図６及び図７を用いて説明する。図６は、ダンパ装置７４が室外空気Ａｏｕｔ（除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔ）を室内Ｒｉｎに搬送する状態を示す三面図である。 The flow of the outdoor air Aout in the damper device 74 will be described below with reference to FIGS. 6 and 7. FIG. FIG. 6 is a trihedral view showing a state in which the damper device 74 conveys the outdoor air Aout (the dehumidified air Aout and the humidified air Aout) to the indoor room Rin.
　ダンパ装置７４のダンパ７４ａは、回転軸７４ｃを中心に回転稼働でき、図６では、室外Ｒｏｕｔに放出する領域７４ｍ（ダンパ７４ａの周囲部分）が閉じた状態を示している（図７参照）。ダンパ７４ａの凸部７４ｄ、エッジ部７４ｅは、ファン６６によって吹き出された空気の風圧を受け、図６の左上方向（矢印方向）に力が働き、閉まる傾向にある。すなわち、この状態で風速が上がれば上がるほど、風圧が上昇して室外Ｒｏｕｔに放出する領域７４ｍが締まり、室外Ｒｏｕｔに放出する領域７４ｍが閉じた状態の密閉性が強化される。つまり、ダンパ７４ａに負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａと室外Ｒｏｕｔに放出する領域７４ｍ（ダンパ７４ａの周囲部分）との密閉性を助長するように働き、室外Ｒｏｕｔへの室外空気Ａｏｕｔの流れを抑制する。 The damper 74a of the damper device 74 can be rotated around a rotating shaft 74c, and FIG. 6 shows a state in which a region 74m (surrounding portion of the damper 74a) for discharging to the outdoor Rout is closed (see FIG. 7). The convex portion 74d and the edge portion 74e of the damper 74a receive the wind pressure of the air blown out by the fan 66, force acts in the upper left direction (arrow direction) in FIG. 6, and tends to close. That is, the higher the wind speed in this state, the higher the wind pressure, the tighter the area 74m discharged to the outdoor Rout, and the tighter the airtightness of the closed area 74m discharged to the outdoor Rout. That is, the wind pressure of the outdoor air Aout applied to the damper 74a acts to promote sealing between the damper 74a and the area 74m (surrounding portion of the damper 74a) discharged to the outdoor Rout, and the outdoor air Aout to the outdoor Rout restrain the flow of
　図７は、ダンパ装置７４が室外空気Ａｏｕｔ（加湿空気Ａｏｕｔ）を室外Ｒｏｕｔに放出する状態を示す三面図である。 FIG. 7 is a trihedral view showing a state in which the damper device 74 discharges the outdoor air Aout (humidified air Aout) to the outdoor Rout.
　図７は、吸着脱離材５８から脱離した加湿空気Ａｏｕｔを室外Ｒｏｕｔに放出するために、ダンパ装置７４において室外Ｒｏｕｔに通じる部分が開放された状態を示している。図７では、ダンパ７４ａは、回転軸７４ｃを中心に回転して室外Ｒｏｕｔに空気を吹き出すように開口している。ダンパ７４ａの凸部７４ｄ、エッジ部７４ｅは、室内Ｒｉｎに通じる送風路７４ｉの送風路面７４ｊ（ダンパ７４ａの周囲部分）に密着して加湿空気Ａｏｕｔが室内Ｒｉｎ方向に流れるのを抑制する。また、ダンパ７４ａに働く力は、図７の左下方向（矢印方向）となり、室内Ｒｉｎに通じる部分を閉める傾向にある。すなわち、風速が上がれば上がるほど、風圧が上昇して室内Ｒｉｎに通じる部分が締まり、室内Ｒｉｎに通じる部分を閉めた状態の密閉性が強化される。つまり、ダンパ７４ａへ負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａと送風路面７４ｊ（ダンパ７４ａの周囲部分）との密閉性を助長するように働き、室内Ｒｉｎへの室外空気Ａｏｕｔの流れを抑制する。 FIG. 7 shows a state in which a portion of the damper device 74 leading to the outdoor Rout is opened in order to release the humidified air Aout desorbed from the adsorption/desorption material 58 to the outdoor Rout. In FIG. 7, the damper 74a is opened so as to rotate around the rotating shaft 74c and blow out the air to the outdoor Rout. The convex portion 74d and the edge portion 74e of the damper 74a are in close contact with the blowing surface 74j (surrounding portion of the damper 74a) of the blowing passage 74i leading to the room Rin to suppress the flow of the humidified air Aout toward the room Rin. Further, the force acting on the damper 74a is in the lower left direction (arrow direction) in FIG. 7, and tends to close the portion communicating with the room Rin. That is, the higher the wind speed, the higher the wind pressure, the tighter the portion communicating with the room Rin, and the tighter the sealing performance when the portion communicating with the room Rin is closed. That is, the wind pressure of the outdoor air Aout applied to the damper 74a acts to promote sealing between the damper 74a and the blowing surface 74j (the portion surrounding the damper 74a), thereby suppressing the flow of the outdoor air Aout to the indoor Rin. do.
　（実施の形態２）
　次に、本開示の実施の形態２に係る除加湿ユニットが有するダンパ装置７５について、図８を用いて説明する。図８は、ダンパ装置７５が室外空気Ａｏｕｔ（除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔ）を室内Ｒｉｎに搬送する状態を示す三面図である。 (Embodiment 2)
Next, the damper device 75 included in the dehumidifying/humidifying unit according to Embodiment 2 of the present disclosure will be described using FIG. FIG. 8 is a trihedral view showing a state in which the damper device 75 conveys the outdoor air Aout (the dehumidified air Aout and the humidified air Aout) to the indoor room Rin.
　ダンパ７４ａは、回転軸７４ｃを中心に回転稼働でき、図８では、室外Ｒｏｕｔに放出する領域７４ｍ（ダンパ７４ａの周囲部分）が閉じた状態を示している。ダンパ装置７５は、ダンパ７４ａの上流部と下流部とで、室内Ｒｉｎに通じる送風路７５ｉの断面積が異なる点で、上述のダンパ装置７４と異なる。すなわち、ダンパ７４ａは、室内Ｒｉｎに通じる送風路７５ｉにおいて、断面積が漸減する縮流部７５ｋに設けられている。ダンパ７４ａの上流部のダクト断面積Ｓ３と、下流部のダクト断面積Ｓ４とが、Ｓ４＜Ｓ３の関係にあり、室外空気Ａｏｕｔが下流に流れるに従って増速する傾向にある。すなわち、ダンパ７４ａに負荷される室外空気Ａｏｕｔの風圧が増加する傾向にあり、ダンパ７４ａが締まる方向に力が働き密閉性が強化される。つまり、ダンパ７４ａに負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａと室外Ｒｏｕｔに放出する領域７４ｍ（ダンパ７４ａの周囲部分）との密閉性を助長するように働き、室内Ｒｉｎへの室外空気Ａｏｕｔの流れを抑制する。 The damper 74a can rotate around a rotation shaft 74c, and FIG. 8 shows a state in which a region 74m (peripheral portion of the damper 74a) for discharging to the outdoor Rout is closed. The damper device 75 differs from the above-described damper device 74 in that the cross-sectional area of the air duct 75i leading to the room Rin differs between the upstream portion and the downstream portion of the damper 74a. That is, the damper 74a is provided in a contraction portion 75k having a gradually decreasing cross-sectional area in the air passage 75i leading to the room Rin. The duct cross-sectional area S3 of the upstream portion of the damper 74a and the duct cross-sectional area S4 of the downstream portion have a relationship of S4<S3, and the outdoor air Aout tends to increase in speed as it flows downstream. That is, the wind pressure of the outdoor air Aout applied to the damper 74a tends to increase, and a force acts in the direction of tightening the damper 74a, thereby enhancing the airtightness. In other words, the wind pressure of the outdoor air Aout applied to the damper 74a acts to promote sealing between the damper 74a and the region 74m (surrounding portion of the damper 74a) discharged to the outdoor Rout, and the outdoor air Aout to the indoor Rin. restrain the flow of

　本開示の実施の形態３に係る除加湿ユニットが有するダンパ装置７６について、図９Ａ～図９Ｃを用いて説明する。図９Ａは、ダンパ装置７６が室外空気Ａｏｕｔ（除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔ）を室内Ｒｉｎに搬送する状態を示す正面図である。図９Ｂは、図９ＡのＡ－Ａ断面図であり、図９Ｃは、図９Ａの円Ｃの拡大図である。 (Embodiment 3)
A damper device 76 included in a dehumidifying/humidifying unit according to Embodiment 3 of the present disclosure will be described with reference to FIGS. 9A to 9C. FIG. 9A is a front view showing a state in which the damper device 76 conveys the outdoor air Aout (the dehumidified air Aout and the humidified air Aout) to the indoor room Rin. 9B is a cross-sectional view taken along line AA in FIG. 9A, and FIG. 9C is an enlarged view of circle C in FIG. 9A.
　ダンパ７６ａは、回転軸７４ｃを中心に回転稼働でき、図９Ａでは、室外Ｒｏｕｔに放出する領域７６ｍ（ダンパ７６ａの周囲部分）が閉じた状態を示している。すなわち、図９Ａは、除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔを室内Ｒｉｎに搬送する状態を表したものである。図９Ｂ、図９Ｃに示すように、ダンパ７６ａは、ダンパ７６ａの裏面周囲に凸部７６ｆが設けられている点で、上述のダンパ７４ａと異なる。また、ダンパ装置７６は、送風路側に凹部７６ｇが設けられており、凸部７６ｆが嵌まり込む。これによって、ダンパ７６ａと送風路との接触面積が大きくなり密閉性が強化される。つまり、ダンパ７６ａに負荷される室外空気Ａｏｕｔの風圧が、ダンパ７６ａと室外Ｒｏｕｔに放出する領域７６ｍ（ダンパ７６ａの周囲部分）との密閉性を助長するように働き、室外Ｒｏｕｔへの室外空気Ａｏｕｔの流れを抑制する。 The damper 76a can be rotated about a rotating shaft 74c, and FIG. 9A shows a state in which a region 76m (surrounding portion of the damper 76a) for discharging to the outdoor Rout is closed. That is, FIG. 9A shows a state in which the dehumidified air Aout and the humidified air Aout are conveyed to the room Rin. As shown in FIGS. 9B and 9C, the damper 76a differs from the damper 74a described above in that a convex portion 76f is provided around the rear surface of the damper 76a. Further, the damper device 76 is provided with a concave portion 76g on the blowing path side, into which the convex portion 76f is fitted. As a result, the contact area between the damper 76a and the air passage is increased, and the airtightness is enhanced. That is, the wind pressure of the outdoor air Aout applied to the damper 76a acts to promote sealing between the damper 76a and the region 76m (surrounding portion of the damper 76a) discharged to the outdoor Rout, and the outdoor air Aout to the outdoor Rout restrain the flow of

　本開示の実施の形態４に係る除加湿ユニットが有するダンパ装置７７について、図１０Ａ及び図１０Ｂを用いて説明する。図１０Ａは、ダンパ装置７７が室外空気Ａｏｕｔ（除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔ）を室内Ｒｉｎに搬送する状態を示す正面図である。図１０Ｂは、図１０ＡのＡ－Ａ断面図である。 (Embodiment 4)
A damper device 77 included in a dehumidifying/humidifying unit according to Embodiment 4 of the present disclosure will be described with reference to FIGS. 10A and 10B. FIG. 10A is a front view showing a state in which the damper device 77 conveys the outdoor air Aout (the dehumidified air Aout and the humidified air Aout) to the indoor room Rin. FIG. 10B is a cross-sectional view taken along line AA of FIG. 10A.
　ダンパ７７ａは、回転軸７４ｃを中心に回転稼働でき、図１０Ａでは、室外Ｒｏｕｔに放出する領域７７ｍ（ダンパ７７ａの周囲部分）が閉じた状態を示している。すなわち、図１０Ａは、除湿空気Ａｏｕｔ及び加湿空気Ａｏｕｔを室内Ｒｉｎに搬送する状態を表したものである。図１０Ａ、図１０Ｂに示すように、ダンパ７７ａは、裏面に弾性体部材７７ｈが貼り付けてある点で、上述のダンパ７４ａと異なる。これによって、ダンパ７７ａと送風路とが密着接触して密閉性が強化される。つまり、ダンパ７７ａに負荷される室外空気Ａｏｕｔの風圧が、ダンパ７７ａと室外Ｒｏｕｔに放出する領域（ダンパ７７ａの周囲部分）との密閉性を助長するように働き、室外Ｒｏｕｔへの室外空気Ａｏｕｔの流れを抑制する。 The damper 77a can be rotated about a rotating shaft 74c, and FIG. 10A shows a state in which a region 77m (surrounding portion of the damper 77a) for discharging to the outdoor Rout is closed. That is, FIG. 10A shows a state in which the dehumidified air Aout and the humidified air Aout are conveyed to the room Rin. As shown in FIGS. 10A and 10B, the damper 77a differs from the damper 74a described above in that an elastic member 77h is attached to the rear surface. As a result, the damper 77a and the air passage are brought into close contact with each other, thereby enhancing the sealing performance. That is, the wind pressure of the outdoor air Aout applied to the damper 77a acts to promote sealing between the damper 77a and the area (surrounding portion of the damper 77a) that is discharged to the outdoor Rout, and the outdoor air Aout to the outdoor Rout. restrain the flow.
　（効果等）
　以上に説明したように、各実施の形態に係る除加湿ユニットは、以下のように構成されている。 (effects, etc.)
As described above, the dehumidifying/humidifying unit according to each embodiment is configured as follows.
　（１）実施の形態１に係る除加湿ユニット５０は、ファン６６と、吸着脱離材５８と、ヒータ６７と、ダンパ７４ａと、を有する。ファン６６は、室外空気Ａｏｕｔ（本開示における除湿及び加湿の対象となる空気の一例である）を取り込み、室外空気Ａｏｕｔの流れを発生させる。吸着脱離材５８は、室外空気Ａｏｕｔの水分を吸着及び脱離する。ヒータ６７は、脱離のために室外空気Ａｏｕｔを加温する。ダンパ７４ａは、吸着脱離材５８を通過した室外空気Ａｏｕｔの流れの方向を、室内Ｒｉｎと室外Ｒｏｕｔとの間で切換える。そして、除加湿ユニット５０は、ダンパ７４ａへ負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａとダンパ７４ａの周囲部分との密閉性を助長するように働き、ダンパ７４ａが切替える方向とは逆方向への室外空気Ａｏｕｔの流れを抑制するよう構成されている。 (1) The dehumidifying/humidifying unit 50 according to Embodiment 1 has a fan 66, an adsorption/desorption material 58, a heater 67, and a damper 74a. The fan 66 takes in the outdoor air Aout (which is an example of air to be dehumidified and humidified in the present disclosure) and generates a flow of the outdoor air Aout. The adsorption/desorption material 58 adsorbs and desorbs moisture in the outdoor air Aout. A heater 67 heats the outdoor air Aout for desorption. The damper 74a switches the flow direction of the outdoor air Aout that has passed through the adsorption/desorption material 58 between the indoor Rin and the outdoor Rout. In the dehumidifying/humidifying unit 50, the wind pressure of the outdoor air Aout applied to the damper 74a acts to promote sealing between the damper 74a and the surrounding portion of the damper 74a, and the damper 74a switches in the opposite direction. is configured to suppress the flow of the outdoor air Aout.
　（２）実施の形態１に係る除加湿ユニット５０では、ダンパ７４ａが室外空気Ａｏｕｔの流れの方向を室内Ｒｉｎに切換えた場合に、以下のようになる。すなわち、除加湿ユニット５０は、ダンパ７４ａへ負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａと室外Ｒｏｕｔに放出する領域７４ｍ（ダンパ７４ａの周囲部分）との密閉性を助長するように働き、室外Ｒｏｕｔへの室外空気Ａｏｕｔの流れを抑制する。 (2) In the dehumidifying/humidifying unit 50 according to Embodiment 1, the following occurs when the damper 74a switches the flow direction of the outdoor air Aout to the indoor Rin. That is, the dehumidifying/humidifying unit 50 works so that the wind pressure of the outdoor air Aout applied to the damper 74a promotes sealing between the damper 74a and the region 74m (the surrounding portion of the damper 74a) that is discharged to the outdoor Rout. The flow of outdoor air Aout to Rout is suppressed.
　これにより、除加湿ユニット５０は、ダンパ７４ａへ負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａとダンパ７４ａの周囲部分との密閉性を強化できる。つまり、除加湿ユニット５０は、ダンパ７４ａが切り替える方向とは逆方向への室外空気Ａｏｕｔの流れを抑制できるので、除加湿した空気の漏れを減少させ、除湿性能または加湿性能あるいはこの両性能を向上することができる。 Thereby, in the dehumidifying/humidifying unit 50, the air pressure of the outdoor air Aout applied to the damper 74a can strengthen the airtightness between the damper 74a and the surrounding portion of the damper 74a. That is, since the dehumidifying/humidifying unit 50 can suppress the flow of the outdoor air Aout in the direction opposite to the direction in which the damper 74a is switched, leakage of the dehumidified/humidified air is reduced, and the dehumidification performance or the humidification performance or both performances are improved. can do.
　なお、実施の形態１に係る除加湿ユニット５０では、ダンパ７４ａが室外空気Ａｏｕｔの流れの方向を室外Ｒｏｕｔに切換えた場合に、以下のようになる。すなわち、除加湿ユニット５０は、ダンパ７４ａへ負荷される室外空気Ａｏｕｔの風圧が、ダンパ７４ａと室内Ｒｉｎに通じる送風路７４ｉの送風路面７４ｊ（ダンパ７４ａの周囲部分）との密閉性を助長するように働き、室内Ｒｉｎへの室外空気Ａｏｕｔの流れを抑制する。 In addition, in the dehumidifying/humidifying unit 50 according to Embodiment 1, when the damper 74a switches the flow direction of the outdoor air Aout to the outdoor Rout, the following occurs. That is, the dehumidifying/humidifying unit 50 is configured such that the wind pressure of the outdoor air Aout applied to the damper 74a promotes sealing between the damper 74a and the blowing surface 74j (the surrounding portion of the damper 74a) of the blowing passage 74i leading to the room Rin. to suppress the flow of the outdoor air Aout to the indoor room Rin.
　（３）実施の形態２に係る除加湿ユニットでは、ダンパ７４ａは、室内Ｒｉｎに通じる送風路７５ｉにおいて、断面積が漸減する縮流部７５ｋに設けられている。 (3) In the dehumidifying/humidifying unit according to Embodiment 2, the damper 74a is provided in the contraction portion 75k of the air passage 75i leading to the room Rin, the cross-sectional area of which gradually decreases.
　これにより、送風路７５ｉの断面積が小さくなるにつれてダンパ７４ａに負荷される室外空気Ａｏｕｔの風圧が増加していくため、この室外空気Ａｏｕｔの風圧が、ダンパ７４ａとダンパ７４ａの周囲部分との密閉性を強化できる。つまり、実施の形態２に係る除加湿ユニットは、ダンパ７４ａが切り替える方向とは逆方向への室外空気Ａｏｕｔの流れを抑制できるので、除加湿した空気の漏れを減少させ、除湿性能または加湿性能あるいはこの両性能を向上することができる。 As a result, the wind pressure of the outdoor air Aout applied to the damper 74a increases as the cross-sectional area of the air passage 75i becomes smaller. can enhance sexuality. That is, the dehumidifying/humidifying unit according to the second embodiment can suppress the flow of the outdoor air Aout in the direction opposite to the direction in which the damper 74a is switched. Both of these performances can be improved.
　（４）図６に示すように、実施の形態１に係る除加湿ユニット５０では、ダンパ７４ａに凸部７４ｄが設けられている。これにより、除加湿ユニット５０は、ダンパ７４ａの凸部７４ｄに室外空気Ａｏｕｔの風圧を受けることで、ダンパ７４ａとダンパ７４ａの周囲部分との密閉性を強化できる。つまり、図６に示すように、除加湿ユニット５０は、室外Ｒｏｕｔへの室外空気Ａｏｕｔの流れを抑制できるので、除加湿した空気の漏れを減少させ、除湿性能または加湿性能あるいはこの両性能を向上することができる。 (4) As shown in FIG. 6, in the dehumidifying/humidifying unit 50 according to the first embodiment, the damper 74a is provided with the convex portion 74d.
