Description

本発明は、空気中の酸素ガス成分の濃度を高めて供給する機能を備えた送風装置に関するものである。 The present invention relates to an air blower having a function of increasing the concentration of oxygen gas components in air and supplying the oxygen gas component.

従来より、酸素富化膜などのガス富化膜を用いて特定のガス濃度を相対的に向上させるための酸素富化装置や窒素富化装置などが医療用の酸素富化装置、空気調和機、空気清浄機などの機器用に種々提案されている。 Conventionally, oxygen enrichment devices and nitrogen enrichment devices for relatively improving a specific gas concentration using gas enrichment membranes such as oxygen enrichment membranes are medical oxygen enrichment devices and air conditioners. Various proposals have been made for devices such as air purifiers.

例えば酸素濃度を向上させるものとして、分離型空気調和機の室外機に酸素富化手段を設け、その酸素が富化された空気を、送出配管を介して室内機に送り、分離形空気調和機の室内ファンによる送風に酸素富化された空気を混ぜて室内側に放出するようにし、被空調空間である室内の酸素濃度を向上させて、ユーザの快適性の用に供するものがあった。 For example, in order to improve the oxygen concentration, an oxygen enrichment means is provided in the outdoor unit of the separation type air conditioner, and the oxygen enriched air is sent to the indoor unit via the delivery pipe, and the separation type air conditioner Some of the indoor fans are mixed with oxygen-enriched air and discharged to the indoor side to improve the oxygen concentration in the room, which is the air-conditioned space, for the comfort of the user.

しかし、酸素富化膜を用いた酸素富化装置では、酸素富化膜は空気成分の大半を占める窒素と分離させ選択的に酸素を透過させるものの、現在実用化されている酸素富化膜は酸素と同時に少なくとも空気中の水分も透過させる特徴を持っている。 However, in an oxygen enrichment apparatus using an oxygen enriched membrane, the oxygen enriched membrane is separated from nitrogen, which occupies most of the air component, and selectively transmits oxygen. It has the characteristic of allowing at least moisture in the air to permeate simultaneously with oxygen.

即ち、酸素富化膜の１次側の空気に対して、酸素富化膜を透過した２次側では窒素が分離された分だけ相対的に湿度が高くなり露点が１次側の空気に比べて上昇するため、酸素富化膜の２次側配管中でしばしば結露水を発生させてしまうことが知られている（例えば、特許文献１参照）。 That is, relative to the air on the primary side of the oxygen-enriched membrane, the secondary side that has passed through the oxygen-enriched membrane has a relatively high humidity due to the separation of nitrogen, and the dew point is higher than that of the air on the primary side. Therefore, it is known that condensed water is often generated in the secondary side piping of the oxygen-enriched membrane (see, for example, Patent Document 1).

一方、ユーザのニーズとして、酸素富化された空気を吸引して身体のリフレッシュを図ろうとして、酸素富化された空気を鼻や口の周辺で局所的に放出させる酸素富化装置が提案されている。局所の吹出しには酸素富化装置から送気チューブを介してオーディオのヘッドホンのようにして口元など局所に吹出すための道具を人体に装着するようにしている。このような事例としては、他にはマスク状の医療用の酸素供給装置などもある。
特開平５−１１３２２７号公報 On the other hand, as a user's need, an oxygen-enriched device that releases oxygen-enriched air locally around the nose or mouth has been proposed in order to refresh the body by sucking in oxygen-enriched air. ing. For local blowing, a tool for blowing locally such as the mouth is worn on the human body like an audio headphone through an air supply tube from an oxygen enricher. Other examples include a mask-shaped medical oxygen supply device.
JP-A-5-113227

しかしながら、上記従来の技術では、空気調和機などの送風装置の送風に酸素富化された空気を混入させて空調空間中に拡散することで、全体的に酸素濃度を維持させることはできるが、折角生成された高酸素濃度の酸素富化空気を集中的に人体に取り込むことはできず、また局所吹出の酸素富化装置では、多数のユーザがその部屋に存在する場合には、十分に酸素富化された空気を提供し快適空間を提供することは困難であった。 However, in the above-described conventional technology, the oxygen concentration can be maintained as a whole by mixing oxygen-enriched air in the air blown by an air blower such as an air conditioner and diffusing it into the air-conditioned space. The oxygen-enriched air with a high oxygen concentration that is generated at the corner cannot be intensively taken into the human body, and the oxygen-enriching device of the local blowout has sufficient oxygen when there are many users in the room. Providing enriched air and providing a comfortable space has been difficult.

従って両方の機能を兼ね備えた送風装置は、ユーザのニーズを満足させる上で有効な手段のひとつと言える。このとき、被空調空間の酸素濃度を維持改善しつつ、酸素富化ガスの生成に用いるポンプなどの動力装置の騒音等を勘案して、室外に配置したユニットにて酸素富化空気を生成することが有効であるといえる。 Therefore, it can be said that the air blower having both functions is one of effective means for satisfying the user's needs. At this time, while maintaining and improving the oxygen concentration in the air-conditioned space, oxygen-enriched air is generated by a unit placed outdoors in consideration of noise of a power device such as a pump used for generating oxygen-enriched gas. Can be said to be effective.

しかしながら、酸素富化膜の２次側には水分が透過してしまうため、ユーザが局所吹出しの手段により直接吸引を繰り返していると、管路に徐々にたまった水滴が吹出部から出てきてしまうので、吹出部手前に水分の受け部を設け、その受け部に溜まった水を定期的に捨てる必要があった。 However, since water permeates through the secondary side of the oxygen-enriched membrane, when the user repeats direct suction by means of local blowing, water droplets that gradually accumulate in the pipeline come out from the blowing portion. Therefore, it was necessary to provide a moisture receiving portion in front of the blowing portion and periodically discard the water accumulated in the receiving portion.

本発明は、上記課題を解決するもので、酸素富化空気の部屋全体への拡散供給と、高濃度局所吹出しの両機能を有しつつ、酸素富化空気の吹出部から水滴が出ることなく、安心して使用できる送風装置を提供することを目的とするものである。 The present invention solves the above-described problem, and has both functions of diffusing and supplying oxygen-enriched air to the entire room and high-concentration local blowing without causing water droplets to come out from the blowing portion of oxygen-enriched air. An object of the present invention is to provide a blower that can be used with confidence.

上記従来の課題を解決するために、本発明の送風装置は、酸素濃度を高める酸素富化膜と、前記酸素富化膜の下流側に連結される真空ポンプと、前記真空ポンプから吐出される酸素富化空気を吹き出す第１吹出部と第２吹出部と、前記第１吹出部から吹き出された酸素富化空気を被空調空間に送出する送風手段と、前記真空ポンプの下流側に接続され前記酸素富化空気を前記第１吹出部側と第２吹出部側とに切り換える第１の流路切換手段とを設け、前記第２吹出部をさらに前記真空ポンプの上流側と連通させると共にその連通を制御する第２流路切換手段を設けたもので、ユーザは、第１、第２の流路切換手段の操作で、部屋全体の酸素濃度の維持・向上を行う送風装置の送風による酸素富化空気の拡散運転と、局所的に高濃度を供給する局所運転とを選択することができるとともに、酸素富化空気が通る流路内に溜まった水滴を確実に除去することが可能となる。 In order to solve the above-described conventional problems, the blower of the present invention is discharged from the oxygen-enriched film for increasing the oxygen concentration, a vacuum pump connected to the downstream side of the oxygen-enriched film, and the vacuum pump. A first blow-out section and a second blow-out section for blowing out oxygen-enriched air; a blowing means for sending oxygen-enriched air blown out from the first blow-out section to the air-conditioned space; and a downstream side of the vacuum pump. Providing a first flow path switching means for switching the oxygen-enriched air between the first blowing part side and the second blowing part side, and further communicating the second blowing part with the upstream side of the vacuum pump; The second flow path switching means for controlling communication is provided, and the user can operate the first and second flow path switching means to maintain and improve the oxygen concentration of the entire room. Diffusion operation of enriched air and local supply of high concentration It is possible to select the operation place, it is possible to reliably remove the water droplets collected in the flow path through which oxygen-enriched air.

本発明の送風装置は、酸素富化空気の部屋全体への拡散供給と、高濃度局所吹出しの両機能を有しつつ、ユーザが局所吹出しの手段により直接吸引を繰り返しても、管路に溜まった水滴を自動的に処理することができ、快適空間の創造に寄与することができる送風装置を提供することができるものである。 The blower of the present invention has both functions of diffusing and supplying oxygen-enriched air to the entire room and high-concentration local blowing, and even if the user repeats direct suction by means of local blowing, it accumulates in the pipeline. It is possible to provide a blower that can automatically process water droplets and contribute to the creation of a comfortable space.

The structure is simple, and if the switching valve is arranged in the indoor unit provided with the first blower part, inspection is easy. It will be.

第３の発明は、特に第１の発明の第２の流路切換手段を、第２吹出部と真空ポンプの上流側とを繋ぐ管路と、酸素富化膜から真空ポンプ上流側へ繋がる管路とが合流する位置に設けられ、真空ポンプ上流側への接続を第２吹出口からと酸素富化膜からとを切り換える切換弁にて形成したもので、構成が簡単で、切換弁を比較的デッドスペースが多い室外ユニット側に配することができるので、送風装置が大型化する事が無い。 In the third invention, in particular, the second flow path switching means of the first invention includes a pipe line connecting the second blowing part and the upstream side of the vacuum pump, and a pipe connecting the oxygen-enriched film to the upstream side of the vacuum pump. The connection to the upstream side of the vacuum pump is formed by a switching valve that switches from the second outlet and from the oxygen-enriched membrane. The structure is simple and the switching valve is compared. Since it can be arranged on the outdoor unit side with a large target dead space, the blower device does not increase in size.

第４の発明は、特に第１の発明の第２の流路切換手段を、酸素富化膜と真空ポンプとの間と、第２吹出部とを連通する管路の途中に設けた開閉弁にて形成したもので、構造がシンプルで安価な開閉弁を使用することで、安価で信頼性の高い送風装置が提供できる。 According to a fourth aspect of the present invention, there is provided an on-off valve in which the second flow path switching means of the first aspect of the invention is provided in the middle of a pipe line that communicates between the oxygen-enriched membrane and the vacuum pump and the second outlet.

When the vacuum pump operation is continued for a predetermined time and the on-off valve is closed when the air in the flow path is sucked out, the flow path is pulled by the vacuum pump and becomes a negative pressure, and the water droplets evaporate. Moisture is much better evacuated than just air being evacuated.

第７の発明は、特に第６発明のいずれか1つの発明の開閉弁の上流側に水分を受ける受け部を設けたもので、第２吹出口からの酸素富化空気の吹出し運転を万一長時間続けても、空気中の水分が受け部に溜まるので、吹出部から水滴が出るのを防止することができる。 In the seventh aspect of the invention, in particular, a receiving portion for receiving moisture is provided on the upstream side of the on-off valve of any one of the sixth aspect of the invention, and in the unlikely event that the oxygen-enriched air is blown from the second outlet. Even if it continues for a long time, since the water | moisture content in air accumulates in a receiving part, it can prevent that a water droplet comes out from a blowing part.

第８の発明は、特に第６又は第７の発明の第２吹出部の開閉弁は、少なくとも、第２の流路切換手段によって第２吹出部が真空ポンプ上流側に繋がり真空ポンプ運転が継続している間は、閉弁状態となるようにしたもので、真空ポンプの運転が継続している間に、流路内が負圧になり、水分の受け部に溜まっていた水も蒸発して吸い出され、処理することが可能となる。 In the eighth aspect of the invention, in particular, in the on-off valve of the second outlet part of the sixth or seventh aspect of the invention, at least the second outlet part is connected to the upstream side of the vacuum pump by the second flow path switching means, and the vacuum pump operation is continued. During this time, the valve is closed, and while the vacuum pump continues to operate, the pressure in the flow path becomes negative, and the water accumulated in the moisture receiving part also evaporates. Can be sucked out and processed.

第９の発明は、特に第６〜８の発明のいずれか1つの発明の第２吹出部の開閉弁は、第２吹出部からの酸素富化空気の吹出し運転時以外は閉じているようにしたもので、第２吹出部を使用していない間に、ほこり等が流路内に侵入するのを防ぐことができる。 In the ninth aspect of the invention, in particular, the on-off valve of the second blowing section of any one of the sixth to eighth aspects of the invention is closed except during the operation of blowing oxygen-enriched air from the second blowing section. Thus, it is possible to prevent dust and the like from entering the flow path while the second blowout part is not used.

以下、本発明の実施の形態について、図面参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
以下に、本発明の第1の実施の形態における送風装置を図１を用いて説明する。 (Embodiment 1)
Below, the air blower in the 1st Embodiment of this invention is demonstrated using FIG.

図１は、送風装置の例として空気調和装置を示すもので、空気調和装置は室外ユニット１０と室内ユニット２０から構成され、冷媒ガスが循環するように接続配管（図示せず）で接続されている。室外ユニット１０は、圧縮機１１、熱交換器１２、及び室外送風ファン１３を有するとともに、酸素富化膜(図示せず)を具備した酸素富化膜ユニット３１、酸素富化膜ユニット３１の酸素富化膜前後に差圧を発生するとともに、酸素富化空気を室内側に送出する真空ポンプ３２が設けられている。 FIG. 1 shows an air conditioner as an example of a blower. The air conditioner is composed of an outdoor unit 10 and an indoor unit 20, and is connected by a connection pipe (not shown) so that refrigerant gas circulates. Yes. The outdoor unit 10 includes a compressor 11, a heat exchanger 12, and an outdoor blower fan 13, an oxygen-enriched membrane unit 31 including an oxygen-enriched membrane (not shown), and oxygen in the oxygen-enriched membrane unit 31. A vacuum pump 32 is provided for generating a differential pressure before and after the enriched film and for sending oxygen-enriched air indoors.

一方、室内ユニット２０には、室内送風ファン２１や熱交換器２２を有し、吸い込み口２４、熱交換器２２、室内送風ファン２１、吹出し口２３の順に室内空気が流れて熱交換されるよう送風回路が構成されている。また、室外ユニット１０の真空ポンプ３２から送出された酸素富化空気は送気管４０を介して室内ユニット２０側に誘導されるとともに、送気管４０は、室内ユニット２０に配置された第１の流路切換弁４２に接続されている。第１の流路切換弁４２はリモコン７０によりその流路が切り換えられて送気管４０を通ってきた酸素富化空気を第１吹出部４１側と第２吹出部６０側のいずれかに供給されるようになっている。 On the other hand, the indoor unit 20 has an indoor blower fan 21 and a heat exchanger 22, and indoor air flows in the order of the suction port 24, the heat exchanger 22, the indoor blower fan 21, and the blowout port 23 to exchange heat. A blower circuit is configured. Further, the oxygen-enriched air sent from the vacuum pump 32 of the outdoor unit 10 is guided to the indoor unit 20 side via the air supply pipe 40, and the air supply pipe 40 is connected to the first flow disposed in the indoor unit 20. It is connected to the path switching valve 42. The flow path of the first flow path switching valve 42 is switched by the remote controller 70, and the oxygen-enriched air that has passed through the air supply pipe 40 is supplied to either the first blowing section 41 side or the second blowing section 60 side. It has become so.

なお、第１吹出部４１は第１の流路切換弁４２から第１補助送気管４１ａを介して接続
されており、室内ユニット２０の熱交換器２２付近にその吹出し口を有し、結露水が吹き出されても空気調和機が具備するドレン処理経路（図示せず）により処理されるように構成されている。また、第２吹出部６０は送気管５０を介して第２の流路切換弁４４に繋がっており、この第２の流路切換弁４４は第２補助送気管４３を介して前記第１の流路切換弁４２に繋がるとともに戻り用送気管４５を介して真空ポンプ３２の上流側（吸気側）に繋がっており制御信号に応じて第１の流路切換弁４２側と真空ポンプ３２側への接続を切り換えるように構成されている。なお、戻り用送気管４５は酸素富化膜ユニット３１から真空ポンプ３２に繋がる送気管３５に合流するように配されている。 The first outlet 41 is connected from the first flow path switching valve 42 via the first auxiliary air supply pipe 41a, has the outlet near the heat exchanger 22 of the indoor unit 20, and has condensed water. Even if the air is blown out, it is configured to be processed by a drain processing path (not shown) provided in the air conditioner. The second outlet 60 is connected to the second flow path switching valve 44 via the air supply pipe 50, and the second flow path switching valve 44 is connected to the first air supply pipe 43 via the first auxiliary air supply pipe 43. It is connected to the flow path switching valve 42 and is connected to the upstream side (intake side) of the vacuum pump 32 via the return air supply pipe 45 and to the first flow path switching valve 42 side and the vacuum pump 32 side according to the control signal. The connection is switched. The return air supply pipe 45 is arranged so as to join the air supply pipe 35 connected to the vacuum pump 32 from the oxygen-enriched membrane unit 31.

以上の構成による、動作、作用は以下の通りである。 The operation and action of the above configuration are as follows.

ユーザがリモコン７０により第２吹出部６０に酸素富化空気を吹出すよう運転の操作を行うと、第１の流路切換弁４２は送気管４０と第２補助送気管４３が接続されるよう動き、第１吹出部４１に繋がる第１補助送気管４１ａは送気管４０との接続が断たれる。同時に第２の流路切換弁４４は第２補助送気管４３と送気管５０を接続するように切り換わり、戻り用送気管４５はこの第２の流路切換弁４４位置にて接続を断たれることになる。 When the user performs an operation of blowing oxygen-enriched air to the second blowing section 60 using the remote controller 70, the first flow path switching valve 42 is connected to the air supply pipe 40 and the second auxiliary air supply pipe 43. The first auxiliary air supply pipe 41a that moves and is connected to the first blowout portion 41 is disconnected from the air supply pipe 40. At the same time, the second flow path switching valve 44 is switched to connect the second auxiliary air feeding pipe 43 and the air feeding pipe 50, and the return air feeding pipe 45 is disconnected at the position of the second flow path switching valve 44. Will be.

すなわち、真空ポンプ３２から送出されてくる酸素富化空気は第１の流路切換弁４２、続いて第２の流路切換弁４４を通って第２吹出部６０から吹出されることとなる。この局所吹出しによる酸素富化空気のユーザの吸引は通常１０分程度で良いため、その所定の時間がきた時点あるいはユーザが終了操作を行った時点で、一旦真空ポンプ３２の運転を停止すると共に、第１の流路切換弁４２を送気管４０と第１補助送気管４１ａが接続するように切り換え、第２吹出部６０側への接続を断つこととなる。同時に第２の流路切換弁４４は送気管５０と戻り用送気管４５が接続するよう切り換わり第１の流路切換弁４２側への接続を断つこととなる。この状態にて再び真空ポンプ３２を運転する。酸素富化ユニット３１は酸素富化膜により空気が通過するには負荷があるが、第２吹出部６０から真空ポンプ３２に至る経路は空気が通過する際の負荷は少ないため、第２吹出部６０から逆に空気がすい込まれて勢い良く流れていくことになり、その空気の勢いによって管路内の結露水を吸い出すこととなり、真空ポンプ３２を通過したその結露水は、送気管４０、第１の流路切換弁４２、第１補助送気管４１ａを通って、第１吹出部４１から排出されるが、前述したように結露水が吹き出されても空気調和機の具備するドレン処理経路（図示せず）により処理されるように構成されているため問題はなく、所定時間（必要最適な時間は送気管の太さや長さ、また真空ポンプの能力等によって異なってくるが通常数分程度あれば可能）この運転を行うことにより第２吹出部６０側の送気管５０等の管路内の水分を除去することが可能となり、ユーザが水分を処理するというメンテナンスは不用となる。 In other words, the oxygen-enriched air sent from the vacuum pump 32 is blown out from the second blowing section 60 through the first flow path switching valve 42 and then through the second flow path switching valve 44. Since the user's suction of the oxygen-enriched air by this local blowout is usually about 10 minutes, the operation of the vacuum pump 32 is once stopped when the predetermined time comes or when the user performs the end operation, The first flow path switching valve 42 is switched so that the air supply pipe 40 and the first auxiliary air supply pipe 41a are connected, and the connection to the second blowing section 60 side is cut off. At the same time, the second flow path switching valve 44 is switched so that the air supply pipe 50 and the return air supply pipe 45 are connected, and the connection to the first flow path switching valve 42 side is cut off. In this state, the vacuum pump 32 is operated again. The oxygen-enriched unit 31 has a load to allow air to pass through the oxygen-enriched film, but the path from the second blowing unit 60 to the vacuum pump 32 has a small load when air passes, so the second blowing unit On the contrary, the air is rubbed from 60 and flows vigorously, and the condensed water in the pipe line is sucked out by the momentum of the air, and the condensed water passing through the vacuum pump 32 is supplied to the air supply pipe 40, The first flow switching valve 42 and the first auxiliary air supply pipe 41a are discharged from the first blow-out portion 41. As described above, even if condensed water is blown out, the drain treatment path provided in the air conditioner There is no problem because it is configured to be processed by (not shown), and the predetermined time (the required optimum time varies depending on the thickness and length of the air pipe, the capacity of the vacuum pump, etc., but usually several minutes This is possible if possible Can be water in the second conduit, such as a flue 50 of the outlet portion 60 side is removed by performing a result, the maintenance of the user to process the moisture becomes unnecessary.

（実施の形態２）
次に本発明の第２の実施の形態における空気調和装置を、図２を用いて説明する。なお、上記第１の実施の形態と同一部分については、同一符号を付してその説明を省略する。 (Embodiment 2)
Next, the air conditioning apparatus in the 2nd Embodiment of this invention is demonstrated using FIG. Note that the same portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

第２吹出部６０は送気管５０を介して第１の流路切換弁４２に繋がると共に、送気管５０は戻り用送気管４５にも合流して繋がっている。また、酸素富化膜ユニット３１と真空ポンプ３２を繋ぐ送気管３４はその間に第２の流路切換弁３３が設けられた状態となっており、その第２の流路切換弁３３は真空ポンプ３２へ繋がる送気管３４を酸素富化膜ユニット３１からの送気管３５と戻り用送気管４５とで切り換えるようになっている。 The second blowing section 60 is connected to the first flow path switching valve 42 through the air supply pipe 50, and the air supply pipe 50 is joined and connected to the return air supply pipe 45. The air pipe 34 connecting the oxygen-enriched membrane unit 31 and the vacuum pump 32 is provided with a second flow path switching valve 33 therebetween, and the second flow path switching valve 33 is a vacuum pump. The air supply pipe 34 connected to 32 is switched between the air supply pipe 35 from the oxygen-enriched membrane unit 31 and the return air supply pipe 45.

今、ユーザがリモコン７０により第２吹出部６０に酸素富化空気を吹出す運転の操作を行うと、第１の流路切換弁４２は送気管４０と送気管５０が接続されるよう動き、第１吹出部４１に繋がる第１補助送気管４１ａは送気管４０との接続が断たれる。同時に第２の流路切換弁３３は酸素富化膜ユニット３１からの送気管３５と送気管３４を接続するよう
に切り換わり、戻り用送気管４５はこの第２の流路切換弁３３位置にて接続を断たれることになる。すなわち、真空ポンプ３２から送出されてくる酸素富化空気は第１の流路切換弁４２を通って第２吹出部６０から吹出されることとなる。この局所吹出しによる酸素富化空気のユーザの吸引は通常１０分程度で良いため、その所定の時間がきた時点あるいはユーザが終了操作を行った時点にて、一旦真空ポンプ３２の運転を停止すると共に、第１の流路切換弁４２を送気管４０と第１補助送気管４１ａが接続するように切り換え、第２吹出部６０側への接続を断つこととなる。 Now, when the user performs an operation of blowing oxygen-enriched air to the second blowing section 60 by the remote controller 70, the first flow path switching valve 42 moves so that the air feeding pipe 40 and the air feeding pipe 50 are connected, The first auxiliary air supply pipe 41 a connected to the first blow-out portion 41 is disconnected from the air supply pipe 40. At the same time, the second flow path switching valve 33 is switched so as to connect the air feeding pipe 35 and the air feeding pipe 34 from the oxygen-enriched membrane unit 31, and the return air feeding pipe 45 is located at the position of the second flow path switching valve 33. Will be disconnected. In other words, the oxygen-enriched air sent from the vacuum pump 32 is blown out from the second blowing unit 60 through the first flow path switching valve 42. Since the user's suction of the oxygen-enriched air by this local blowout is usually about 10 minutes, the operation of the vacuum pump 32 is once stopped when the predetermined time comes or when the user performs the end operation. The first flow path switching valve 42 is switched so that the air supply pipe 40 and the first auxiliary air supply pipe 41a are connected, and the connection to the second blowing section 60 side is cut off.

同時に第２の流路切換弁３３は戻り用送気管４５が真空ポンプ３２に繋がる送気管３４に接続するよう切り換わり酸素富化膜ユニット３１からの接続を断つこととなる。この状態にて再び真空ポンプ３２を運転する。第２吹出部６０から真空ポンプ３２に至る経路は酸素富化ユニット３１の酸素富化膜のような空気を通過させるための負荷となるものがないため、空気が通過する際の負荷が少なく、第２吹出部６０から逆に空気がすい込まれて勢い良く流れていくことになり、その空気の勢いによって流路内の結露水を吸い出すこととなり、真空ポンプ３２を通過したその結露水は、送気管４０、第１の流路切換弁４２、第１補助送気管４１ａを通って、第１吹出部４１から排出されるが、前述したように結露水が吹き出されても空気調和機が具備するドレン処理経路（図示せず）により処理されるので問題はなく、所定時間（必要最適な時間は送気管の太さや長さ、また真空ポンプ３２の能力等によって異なってくるが通常数分程度あれば可能）この運転を行うことにより第２吹出部６０側管路内の水分を除去することが可能となり、ユーザが水分を処理するというメンテナンスは不用となる。また、この構成はスペースのある室外ユニット１０側に第２の流路切換弁３３を配置するため、スペースの少ない室内ユニット２０側に置く切換弁が少なくてすみ室内ユニット２０の小型化を阻害しない構成とすることができる。 At the same time, the second flow path switching valve 33 is switched so that the return air supply pipe 45 is connected to the air supply pipe 34 connected to the vacuum pump 32 and the connection from the oxygen-enriched membrane unit 31 is cut off. In this state, the vacuum pump 32 is operated again. The path from the second blow-out unit 60 to the vacuum pump 32 has no load to allow air to pass, such as the oxygen-enriched film of the oxygen-enriching unit 31, so the load when air passes is small, On the contrary, air is scrubbed from the second blowing part 60 and flows vigorously, and the condensed water in the flow path is sucked out by the momentum of the air, and the condensed water that has passed through the vacuum pump 32 is The air supply pipe 40, the first flow path switching valve 42, and the first auxiliary air supply pipe 41a are discharged from the first blow-out portion 41. However, as described above, even if condensed water is blown out, an air conditioner is provided. There is no problem because it is processed by a drain processing path (not shown), and a predetermined time (the required optimum time varies depending on the thickness and length of the air supply pipe, the capacity of the vacuum pump 32, etc., but usually about several minutes. This is possible if possible) Possible to remove the water of the second outlet portion 60 side conduit and will by performing maintenance of the user to process the moisture becomes unnecessary. Moreover, since this structure arrange | positions the 2nd flow-path switching valve 33 in the outdoor unit 10 side with a space, there are few switching valves put in the indoor unit 20 side with little space, and it does not inhibit size reduction of the indoor unit 20. It can be configured.

（実施の形態３）
次に本発明の第３の実施の形態における空気調和装置を、図３を用いて説明する。なお、上記第１、２の実施の形態と同一部分については、同一符号を付してその説明を省略する。 (Embodiment 3)
Next, the air conditioning apparatus in the 3rd Embodiment of this invention is demonstrated using FIG. In addition, about the same part as the said 1st, 2nd embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

第２吹出部６０は送気管５０を介して第１の流路切換弁４２に繋がると共に、送気管５０は戻り用送気管４５にも合流して繋がっている。また、酸素富化膜ユニット３１と真空ポンプ３２を繋ぐ送気管３５はその間で戻り用送気管４５と合流している。また、戻り用送気管４５の途中には開閉弁３６が設けられている。 The second blowing section 60 is connected to the first flow path switching valve 42 via the air supply pipe 50, and the air supply pipe 50 is joined and connected to the return air supply pipe 45. Further, the air supply pipe 35 connecting the oxygen-enriched membrane unit 31 and the vacuum pump 32 merges with the return air supply pipe 45 therebetween. An opening / closing valve 36 is provided in the middle of the return air supply pipe 45.

今、ユーザがリモコン７０により第２吹出部６０に酸素富化空気を吹出すよう運転の操作を行うと、第１の流路切換弁４２は送気管４０と送気管５０が接続されるよう動き、第１吹出部４１に繋がる第１補助送気管４１ａは送気管４０との接続が断たれる。同時に開閉弁３６は閉じた状態となっており戻り用送気管４５から真空ポンプ３２への接続は断たれた状態である。すなわち、真空ポンプ３２から送出されてくる酸素富化空気は第１の流路切換弁４２を通って第２吹出部６０から吹出されることとなる。この局所吹出しによる酸素富化空気のユーザの吸引は通常１０分程度で良いため、その所定の時間がきた時点あるいはユーザが終了操作を行った時点にて、一旦真空ポンプ３２の運転を停止すると共に、第１の流路切換弁４２を送気管４０と第１補助送気管４１ａが接続するように切り換え、第２吹出部６０側への接続を断つこととなる。同時に開閉弁３６を開状態に切り換えることにより戻り用送気管４５が真空ポンプ３２に繋がることとなる。 Now, when the user performs an operation for blowing oxygen-enriched air to the second blowing section 60 with the remote controller 70, the first flow path switching valve 42 moves so that the air pipe 40 and the air pipe 50 are connected. The first auxiliary air supply pipe 41a connected to the first blowing part 41 is disconnected from the air supply pipe 40. At the same time, the on-off valve 36 is in a closed state, and the connection from the return air supply pipe 45 to the vacuum pump 32 is cut off. In other words, the oxygen-enriched air sent from the vacuum pump 32 is blown out from the second blowing section 60 through the first flow path switching valve 42. Since the user's suction of the oxygen-enriched air by this local blowout is usually about 10 minutes, the operation of the vacuum pump 32 is once stopped when the predetermined time comes or when the user performs the end operation. The first flow path switching valve 42 is switched so that the air supply pipe 40 and the first auxiliary air supply pipe 41a are connected, and the connection to the second blowing section 60 side is cut off. At the same time, the return air supply pipe 45 is connected to the vacuum pump 32 by switching the open / close valve 36 to the open state.

この状態にて再び真空ポンプ３２を運転する。第２吹出部６０から真空ポンプ３２に至る経路は酸素富化ユニット３１の酸素富化膜のような空気を通過させるための負荷となるものがないため、空気が通過する負荷は少なく、第２吹出部６０から逆に空気がすい込まれて勢い良く流れていくことになり、その空気の勢いによって管路内の結露水を吸い出す
こととなり、真空ポンプを通過したその結露水は、送気管４０、第１の流路切換弁４２、第１補助送気管４１ａを通って、第１吹出部４１から排出されるが、前述したように結露水が吹き出されても空気調和機が具備するドレン処理経路（図示せず）により処理されるので問題はなく、所定時間（必要最適な時間は送気管の太さや長さ、また真空ポンプの能力等によって異なってくるが通常数分程度あれば可能）この運転を行うことにより第２吹出部６０側管路内の水分を除去することが可能となり、ユーザが水分を処理するというメンテナンスは不用となる。 In this state, the vacuum pump 32 is operated again. Since the path from the second blow-out unit 60 to the vacuum pump 32 has no load for allowing air to pass, such as the oxygen-enriched film of the oxygen-enriching unit 31, the load through which the air passes is small. On the contrary, air is scrubbed from the blowout part 60 and flows vigorously, and the condensed water in the pipe line is sucked out by the force of the air, and the condensed water that has passed through the vacuum pump is supplied to the air supply pipe 40. The exhaust gas is discharged from the first outlet 41 through the first flow path switching valve 42 and the first auxiliary air supply pipe 41a. However, as described above, even if condensed water is blown out, the air conditioner has a drain treatment. There is no problem because it is processed by the route (not shown), and the predetermined time (the required optimum time varies depending on the thickness and length of the air supply pipe, the capacity of the vacuum pump, etc., but usually only a few minutes is possible) To do this driving Ri becomes possible to remove moisture second outlet portion 60 side conduit, the maintenance of the user to process the moisture becomes unnecessary.

また、この構成はスペースのある室外ユニット１０側に開閉弁を配置するため、スペースの少ない室内ユニット２０側に置く切換弁が少なくてすみ室内ユニット２０の小型化を阻害しないとともに、切換弁ではなく開閉弁で済むためコスト的にも安くできる構成とすることができる。 Moreover, since this structure arrange | positions an on-off valve in the outdoor unit 10 side with a space, there are few switching valves put in the indoor unit 20 side with little space, and it does not inhibit size reduction of the indoor unit 20, and is not a switching valve. Since an on-off valve is sufficient, it can be configured to be low in cost.

（実施の形態４）
次に本発明の第４の実施の形態を、図４を用いて説明する。なお、上記実施の形態と同一部分については、同一符号を付してその説明を省略する。 (Embodiment 4)
Next, a fourth embodiment of the present invention will be described with reference to FIG. In addition, about the same part as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

図４は、本実施の形態における空気調和装置に接続される吹出部の詳細を示す図である。 FIG. 4 is a diagram showing details of the blow-out unit connected to the air-conditioning apparatus in the present embodiment.

図において、第２吹出部６０には送気管５０が繋がっておりが、その送気管５０の先には水分の受け部５１が設けられその後を再び送気管５２が繋がり、その送気管５２の先には開閉弁５３が設けられている。この開閉弁５３の後には再び送気管５４が設けられ、その先は開放となって吹出せるようになっている。 In the figure, the air supply pipe 50 is connected to the second blowing part 60, but the water receiving part 51 is provided at the tip of the air supply pipe 50, and then the air supply pipe 52 is connected again, and the tip of the air supply pipe 52 is connected. Is provided with an on-off valve 53. An air supply pipe 54 is provided again after the on-off valve 53, and the tip of the air supply pipe 54 is opened so that it can be blown out.

今、ユーザがリモコン７０により第２吹出部６０に酸素富化空気を吹出すよう運転の操作を行うと、この開閉弁５３は開状態となり、上記実施の形態同様、この第２吹出部６０から酸素富化空気を吹出す。この局所吹出しによる酸素富化空気のユーザの吸引は通常１０分程度で良いが、ユーザの希望により時間が長く運転されたとしても流路内に溜まって少しづつ押し出されてくる水滴は受け部５１にて受けられ、第２吹出部６０から吹出すことはない。そしてユーザが終了操作を行った時点にて、開閉弁５３を閉状態にする。このとき第２吹出部６０から逆に空気がすい込まれて流れていくことになるが、開閉弁５３が閉じているため送気管５０や戻り用送気管４５内は負圧となることにより、流路内の水滴や受け部５１に溜まった水滴が蒸発して内部空気といっしょに吸い出されていくことになる。すなわち、流路内の水滴が多かったり、受け部５１に水が溜まっている状態であってもその水分を排出することも可能となる。 Now, when the user performs an operation of blowing oxygen-enriched air to the second blowing part 60 by the remote controller 70, the on-off valve 53 is opened, and from the second blowing part 60 as in the above embodiment. Blow out oxygen-enriched air. The user's suction of the oxygen-enriched air by this local blowout may normally be about 10 minutes, but even if the operation is performed for a long time according to the user's request, the water droplets that accumulate in the flow path and are pushed out little by little are received by the receiving portion 51. And is not blown out from the second blowing unit 60. When the user performs the end operation, the on-off valve 53 is closed. At this time, air flows from the second blowing part 60 in reverse, but since the on-off valve 53 is closed, the air supply pipe 50 and the return air supply pipe 45 have a negative pressure. The water droplets in the flow path and the water droplets accumulated in the receiving part 51 are evaporated and sucked out together with the internal air. That is, even if there are many water droplets in the flow path or water is accumulated in the receiving portion 51, the water can be discharged.

また、この開閉弁５３の動作において、第２吹出部６０から酸素富化空気を吹出す時以外は閉状態にする構成とすれば、この第２吹出部６０からほこり等が流路内に入ることも防止できることとなる。 Further, in the operation of the on-off valve 53, if the configuration is set to a closed state except when oxygen-enriched air is blown from the second blowing part 60, dust or the like enters the flow path from the second blowing part 60. This can also be prevented.

以上のように、本発明にかかる送風装置は、酸素富化空気の部屋全体への拡散供給と、高濃度局所吹出しの両機能を有しつつ、管路に溜まった水滴が自動的に処理されるので、空気調和機に限らず、家庭用・業務用空気清浄機など、送風装置を備えた各種機器に適用が可能である。 As described above, the blower according to the present invention has both functions of diffusing and supplying oxygen-enriched air to the entire room and high-concentration local blowing, and automatically processes water droplets accumulated in the pipeline. Therefore, the present invention is not limited to an air conditioner, and can be applied to various devices including a blower, such as home and commercial air purifiers.
