Description

本発明は誘引吹出口に関するものである。   The present invention relates to an induction outlet.

送風動力削減を目的として、空調機からの供給空気を通常よりも低温、少風量化して室内などの被空調空間に設けた吹出口から給気し、空調を行う低温送風空調システムがある。この空調システムに、一般的なふく流吹出口を用いると、供給空気が低温少風量のために、気流が拡散せずコールドドラフトと結露が発生する。   For the purpose of reducing blower power, there is a low-temperature blower air-conditioning system that performs air conditioning by supplying air from an air conditioner at a lower temperature and a lower air volume than normal and supplying air from an air outlet provided in an air-conditioned space such as a room. When a general exhaust outlet is used in this air conditioning system, the supply air is cold and the amount of air is low, so that the airflow does not diffuse and cold draft and condensation occur.

実開平７−４１３４５号公報Japanese Utility Model Publication No. 7-41345

これを防ぐために特許文献１のようなの吹出口が提案されている。この吹出口には、拡散性の低下を防ぐために旋回羽根を設けているが、構造が複雑で圧力損失が大きく騒音発生の問題がある。さらに、吹出口の最下面である室内開口部で室内空気を誘引するので吹出口内部で結露が発生する。そのため吹出口全体の断熱処理が必要となる。しかも、低温の供給空気と誘引空気は偏って混合されるためにドラフトが発生しやすくなる。   In order to prevent this, a blower outlet like patent document 1 is proposed. The air outlet is provided with swirl vanes in order to prevent a decrease in diffusibility, but has a complicated structure, a large pressure loss, and a problem of noise generation. Furthermore, since indoor air is attracted | guided | derived by the indoor opening part which is the lowermost surface of a blower outlet, dew condensation arises inside a blower outlet. Therefore, the heat insulation process of the whole blower outlet is needed. Moreover, since the low-temperature supply air and the attraction air are mixed unevenly, a draft is likely to occur.

本発明は上記課題を解決するため、外部から送り込まれた供給空気で被空調空間の空気を誘引混合してその混合空気を前記被空調空間へ吹出す本体を、備え、この本体内に環状の間隔部を形成し、この間隔部の周方向へ前記供給空気が送り込まれるように送気口を、設け、前記間隔部の風下に、前記供給空気を噴出する空気噴出口を、前記間隔部に沿ってその周方向に複数分割配置し、前記空気噴出口の風下に、誘引口を、前記空気噴出口から噴出する前記供給空気が吹き込まれることで前記被空調空間の空気を誘引するように前記空気噴出口毎に分割配置して、前記誘引口と前記誘引口の間に前記誘引空気を前記誘引口の全周に周り込ませる誘導案内路を、設け、前記誘引口の風下に、前記供給空気と前記誘引空気の前記混合空気を前記被空調空間へ誘導案内する混合空気吹出風路を、形成し、前記誘引空気を前記被空調空間から前記誘引口へ誘導案内する誘引風路を、形成したことを最も主要な特徴とする。   In order to solve the above problems, the present invention includes a main body that attracts and mixes air in an air-conditioned space with supply air sent from outside and blows the mixed air to the air-conditioned space. An air supply port is formed so as to form an interval portion, and the supply air is sent in the circumferential direction of the interval portion, and an air outlet for ejecting the supply air is provided in the interval portion leeward of the interval portion. Along the circumferential direction along the circumferential direction, the induction air is blown into the lee of the air outlet, and the supply air blown out from the air outlet is blown to attract the air in the air-conditioned space. A guide guide path is provided between each of the air inlets, the guide air passage is arranged around the entire circumference of the air inlet, and the supply is provided leeward of the air inlet. The mixed air of air and the attraction air The mixed air outlet air path for guiding the conditioning space, formed, attractants air passage for guiding the attracted air from the object conditioned space to the attraction port, and the most important feature that formed was.

請求項１、２の発明によれば、
（１）本体の間隔部に沿って供給空気が渦巻き状に旋回して全周に行き渡るので、混合空気を被空調空間に均等に吹出すことができ拡散性が低下しない。簡単な構造でコンパクト化を図れてスペースをとらず、圧力損失が少なく乱流を防止してスムースに吹出しでき、低騒音となる。
（２）本体内部で低温の供給空気とそれよりも高温の誘引空気を混合して吹出すので空気噴出口より風下での結露発生を防止できる。そのため、誘引口と混合空気吹出風路の断熱が不要となって断熱処理範囲が少なくて済み、製作が容易となる。
（３）誘引空気を誘引口の全周から誘引できるので圧力損失が少なく、供給空気風量に対する誘引空気の風量（混合比）を多く確保できる。そのため、混合空気の吹出風量の増加を図れて、拡散性が良好となり温度ムラがなくなる。

This eliminates the need for heat insulation between the inlet and the mixed air blowing air passage, reduces the heat insulation treatment range, and facilitates production.
(3) Since the attracting air can be attracted from the entire circumference of the attracting port, there is little pressure loss, and a large air volume (mixing ratio) of the attracting air with respect to the supply air volume can be secured. Therefore, the amount of air blown out from the mixed air can be increased, the diffusibility is improved, and temperature unevenness is eliminated.
(4) Since the air outlet and the inlet are divided in the circumferential direction or only a part of the circumferential direction, the static pressure is reduced, the air current reaching distance is extended, and the diffusibility is improved.

(1) The axial position adjustment and the circumferential position adjustment of the blow-out portion can be easily performed by simply moving the bolt and nut member back and forth. For example, it can also be used for adjusting the clearance between the ceiling plate and the blowing part and adjusting the blowing direction.

請求項６の発明によれば、

図例では供給空気導入部８の筐体１６の開口部に、吹出部９の外壁体１１の一部を風上側へ突出させて摺動自在に外嵌し、供給空気導入部８の仕切体１７と内壁体１２とを固定具Ｒで連結しているが、仕切体１７と外壁体１１を固定具Ｒで連結してもよく、その構成、構造の変更は自由であり、図例に限定されるものではない。また、供給空気導入部８の内周面は丸形となっているが多角形でも良く、固定具Ｒはボルトナット部材１０以外の機構や構造、構成のものであっても良い。   In the illustrated example, a part of the outer wall body 11 of the blowing portion 9 is protruded toward the windward side in the opening of the housing 16 of the supply air introduction portion 8 so as to be slidably fitted. 17 and the inner wall body 12 are connected by the fixture R, but the partition body 17 and the outer wall body 11 may be connected by the fixture R, and the configuration and structure can be freely changed, and are limited to the illustrated examples. Is not to be done. Further, the inner peripheral surface of the supply air introduction portion 8 is round, but may be polygonal, and the fixture R may be a mechanism, structure, or configuration other than the bolt nut member 10.

この供給空気導入部８に送り込まれた供給空気は、間隔部２に沿って回りながら拡散して空気噴出口４を通過し、誘引口５に向かって噴出する。その際、空気噴出口４と誘引口５との間隙部が負圧となって、被空調空間Ｓの空気を誘引風路７を介して誘引する。誘引空気は誘導案内路１９を介して周り込み誘引口５の全周から吸込まれて供給空気と混合する。そのため混合空気吹出風量に対する供給空気風量：誘引空気風量の比率を例えば６：４のように多くできる。混合空気は、混合空気吹出風路６を通り被空調空間Ｓに向かって４方向に吹出す。例えば、冷房時、混合空気吹出風路６では１３℃の低温の供給空気と、それよりも高温の２７℃の誘引空気を混合するので結露は生じない。なお、供給空気は誘引混合された時点で被空調空間Ｓの露点温度より高温で絶対湿度が低くなるように設定するが変更は自由である。   The supply air sent into the supply air introduction part 8 diffuses while rotating along the interval part 2, passes through the air outlet 4, and is ejected toward the induction port 5. At that time, the gap between the air outlet 4 and the induction port 5 becomes negative pressure, and the air in the air-conditioned space S is attracted through the induction air passage 7. The attraction air is sucked in from the entire circumference of the entrainment inlet 5 through the guide guide path 19 and mixed with the supply air. Therefore, the ratio of the supply air flow rate to the induced air flow rate with respect to the mixed air blowing flow rate can be increased as 6: 4, for example. The mixed air is blown in four directions toward the air-conditioned space S through the mixed air blowing air passage 6. For example, at the time of cooling, the mixed air blowing air passage 6 mixes the supply air having a low temperature of 13 ° C. and the induced air having a higher temperature of 27 ° C., so that condensation does not occur. The supply air is set to be higher than the dew point temperature of the air-conditioned space S when it is attracted and mixed, but it can be changed freely.

なお、本発明は上述の実施例に限定されず、本発明の要旨を逸脱しない範囲で設計変更自由である。例えば、空気噴出口４と誘引口５の分割数の増減は自由で、図６は３分割、図７は２分割した例を示している。図８は、空気噴出口４を、間隔部２に沿ってその周方向の一部に配置し、空気噴出口４の風下に、誘引口５を、空気噴出口４から噴出する供給空気が吹き込まれることで被空調空間Ｓの空気を誘引するように空気噴出口４に沿って配置して、誘引口５の周方向両端部の間に誘引空気を誘引口５の全周に周り込ませる誘導案内路１９を、設けた例を示している。さらに、図９に示すように、誘引風路７及び混合空気吹出風路６は、風上から風下に向かって拡大する四角を含む多角形の環状に形成しても良い。また、ガイド部２０を省略するも自由である。   In addition, this invention is not limited to the above-mentioned Example, A design change is freely possible in the range which does not deviate from the summary of this invention. For example, the number of divisions of the air outlet 4 and the induction port 5 can be freely increased and decreased. FIG. 6 shows an example in which the number of divisions is three, and FIG. In FIG. 8, the air ejection port 4 is arranged along a part of the circumferential direction along the interval portion 2, and supply air that ejects the induction port 5 from the air ejection port 4 is blown into the lee of the air ejection port 4. Is arranged along the air outlet 4 so as to attract the air in the air-conditioned space S, and the induction air is guided around the entire circumference of the induction port 5 between the circumferential ends of the induction port 5.
