Description

超小型燃焼装置用防風装置Windproof device for ultra-compact combustion equipment
　本発明は、暖房服に用いられる暖房機の超小型燃焼装置に関し、特にその防風装置に関する。 The present invention relates to an ultra-compact combustion device for a heater used for a heating garment, and more particularly to a windproof device for the same.
　一般に、この種の超小型燃焼装置は、図１に示されているように、縦向きであって、上側に吸気孔１を、下側に排気孔２を有し、それらの間に、ノズル３を有するエゼクタ４及びその下流に有孔セラミックバーナ５を含む燃焼室６を有する燃焼器本体７を含む。ガスが、ガスボンベ８からノズル３を通してエゼクタ４に噴出されることにより、エゼクタ作用で大気から吸気孔１を通して空気を吸い込み、それによって、ガスと吸い込まれた空気とが混合して混合気を作る。混合気は、セラミックバーナ５の多数の孔９を通して燃焼室１０に流入し、点火プラグ１１による点火火花で着火し、セラミックバーナ面に火炎を形成して燃焼を維持する。燃焼による排気は、排気孔２を通して大気に放出される。参照番号１２は、燃焼によって発生する熱によって加熱される熱負荷装置、例えばヒートポンプを指す。 In general, this type of micro-combustion apparatus, as shown in FIG. 1, is vertically oriented, has an intake hole 1 on the upper side and an exhaust hole 2 on the lower side, and a nozzle between them. 3 and a combustor body 7 having a combustion chamber 6 containing a perforated ceramic burner 5 downstream thereof. When the gas is ejected from the gas cylinder 8 through the nozzle 3 to the ejector 4, air is sucked from the atmosphere through the intake hole 1 by the ejector action, whereby the gas and the sucked air are mixed to form an air-fuel mixture. The air-fuel mixture flows into the combustion chamber 10 through a large number of holes 9 in the ceramic burner 5 and is ignited by an ignition spark by the spark plug 11 to form a flame on the ceramic burner surface and maintain combustion. Exhaust due to combustion is released to the atmosphere through the exhaust hole 2. Reference numeral 12 refers to a heat load device, such as a heat pump, that is heated by heat generated by combustion.
　燃焼室での燃焼を維持するためには、吸気孔及び排気孔が、風が吸気孔及び排気孔に侵入して火炎の吹き消しをもたらす風圧の影響を受けないことが重要である。そのため、吸気孔及び排気孔に直接風が侵入しないように防風板１３、１４をそれぞれ設ける必要がある。防風板は、吸気孔及び排気孔を完全に覆う大きさを有し、且つ孔の面より間隔をあけて設置され、間隙から吸気、排気が行われるようにする。しかし、この構成では、風が強いときには、斜め横方向からの風によって吸気孔及び排気孔が依然として風圧の影響を受けるため、火炎の吹き消しを完全に防止することはできなかった。 In order to maintain combustion in the combustion chamber, it is important that the intake and exhaust holes are not affected by the wind pressure that causes the wind to enter the intake and exhaust holes and blow out the flame. Therefore, it is necessary to provide windbreak plates 13 and 14 so that wind does not directly enter the intake holes and the exhaust holes. The windbreak plate has a size that completely covers the intake hole and the exhaust hole, and is installed at a distance from the surface of the hole so that intake and exhaust are performed from the gap. However, in this configuration, when the wind is strong, the intake holes and the exhaust holes are still affected by the wind pressure due to the wind from the oblique lateral direction, so that the blow-off of the flame cannot be completely prevented.
　その解決策として考えられたのが、燃焼器本体表面に、吸気孔及び排気孔の面から間隔をあけて大きな共通の単一の防風板を設置することであった。完全ではないが、確かに風の影響を相当程度防止することができることが分かった。また、排気孔からの排気の大部分は、防風板と燃焼器本体の表面との間の空間から側方に確実に放出されることがわかった。しかし排気の一部が、防風板と燃焼器本体表面との間の空間を通って吸気孔に吸い込まれることがあり、そのため混合気中の酸素濃度が減少し、時として燃焼室での火炎の立ち消え現象が見受けられた。 A possible solution was to install a large common single windbreak plate on the surface of the combustor body, spaced from the surfaces of the intake and exhaust holes. Although it is not perfect, it has been found that it can certainly prevent the effects of wind. Further, it has been found that most of the exhaust from the exhaust hole is reliably discharged sideways from the space between the windbreak plate and the surface of the combustor body. However, part of the exhaust gas may be sucked into the intake holes through the space between the windbreak plate and the combustor body surface, which reduces the oxygen concentration in the mixture and sometimes causes the flame in the combustion chamber The disappearing phenomenon was observed.
　本発明の目的は、燃焼器に対する風の影響を極力防止し併せてそのような火炎の立ち消えを完全に防止するようにした超小型燃焼装置用の防風装置を提供することにある。 An object of the present invention is to provide a windbreak device for a microcombustion device that prevents the influence of wind on the combustor as much as possible and completely prevents such a flame from extinguishing.
　本発明の上記の目的は、燃焼装置の燃焼器本体を覆い、且つ燃焼器本体の吸気孔及び排気孔に整合して位置する開口部を有するケース蓋に装着され、互いに隔絶され且つ周壁によって囲まれた吸気室及び排気室と、吸気室に通ずる側方窓及び排気室に通ずる排気開口部と、を有する防風ボックスを含み、防風ボックスが、排気開口部を覆って該排気開口部から間隔を隔てて設けられた防風板を有する、超小型燃焼装置用の防風装置を提供することによって達成される。 The above object of the present invention is attached to a case lid that covers the combustor body of the combustion device and has openings positioned in alignment with the intake and exhaust holes of the combustor body, and is isolated from each other and surrounded by a peripheral wall. A windproof box having an intake chamber and an exhaust chamber, and a side window that communicates with the intake chamber and an exhaust opening that communicates with the exhaust chamber. The windbreak box covers the exhaust opening and is spaced from the exhaust opening. This is achieved by providing a windproof device for a microcombustor having windshield plates spaced apart.
　本発明によれば、防風ボックスの吸気室と排気室との隔絶は防風ボックスのほぼ中間に位置する仕切り壁によって果たされる。
　本発明の他の実施形態では、排気室と吸気室との隔絶は、排気室を、排気孔に整合して位置する開口部から排気開口部まで延びる排気ダクトとして構成することによっても果たされる。
　好ましくは、斜め側方から吸気室に侵入しようとする風を遮るために、庇が窓に隣接して防風ボックスの側縁から張り出して形成される。また、ケース蓋には、強風の際、側方窓を通して吸気室に、また排気開口部を通して排気室に侵入しようとする風をできるだけ遮るために微細目のメッシュ（金網）が側方窓を覆って、又防風板との隙間を覆って設けられるのがよい。 According to the present invention, the separation between the intake chamber and the exhaust chamber of the windproof box is achieved by the partition wall located approximately in the middle of the windproof box.
In another embodiment of the present invention, the separation between the exhaust chamber and the intake chamber is also achieved by configuring the exhaust chamber as an exhaust duct extending from the opening located in alignment with the exhaust hole to the exhaust opening.
Preferably, in order to block the wind from entering the intake chamber from an oblique side, the ridge is formed so as to protrude from the side edge of the windproof box adjacent to the window. In case of strong wind, the case lid is covered with a fine mesh (metal mesh) to cover the side window in order to block as much as possible the wind that tries to enter the exhaust chamber through the side window and through the exhaust opening. In addition, it is preferable to cover the gap with the windbreak plate.
　本発明の上記構成では、吸気孔への吸気は側方窓及び吸気室を通して行われ、排気は排気孔から排気室又は排気ダクト及び排気開口部を通して大気に放出することによって行われるが、吸気及び排気が風の影響を受けることがほとんどなく、また吸気室と排気室とが互いに隔絶されているため排気孔からの燃焼排気が、吸気孔に決して吸い込まれることがなく、したがって、混合気中の酸素の減少による燃焼火炎の立ち消え現象は全く起こらない。また防風ボックスの排気室に通じる排気開口部は、これに対峙した防風板で覆われているからむき出しの場合よりも風の影響をより少なくすることができる。 In the above configuration of the present invention, intake to the intake hole is performed through the side window and the intake chamber, and exhaust is performed by discharging from the exhaust hole to the atmosphere through the exhaust chamber or the exhaust duct and the exhaust opening. The exhaust is hardly affected by the wind, and the exhaust chamber and the exhaust chamber are isolated from each other, so that the combustion exhaust from the exhaust hole is never sucked into the intake hole, so The extinction phenomenon of the combustion flame due to the decrease in oxygen does not occur at all. Further, since the exhaust opening leading to the exhaust chamber of the windproof box is covered with a windproof plate facing the exhaust opening, the influence of wind can be reduced more than in the case of the bare.

　図２及び３を参照すると、本発明による防風装置２０は、図１に示ものと同様の超小型の燃焼装置に適用される。燃焼装置は燃焼器本体２１を含み、これを覆うケース蓋２２が、燃焼器本体２１の吸気孔２３及び排気孔２４にそれぞれ整合した開口部２５及び２６を有する。防風装置２０は、吸気孔２３及び排気孔２４を覆うようになった大きさを有し、且つケース蓋２２に固定して取り付けられた防風ボックス２７を含む。ケース蓋２２及びは防風ボックス２７は、プラスチックでそれぞれ一体成型されるのが好ましい。防風ボックス２７は、その周囲に囲い壁２８を有し、且つ仕切り壁３１によって互いに隔絶された吸気室３２及び排気室３３を有する。左右側壁部分２９、２９には吸気室３２に通ずる側方窓３０が形成されている。防風ボックス２７には、また、その正面に、排気孔２４からの燃焼排気を排気室３３を通して大気に排出するための排気開口部３４が設けられている。かくして、吸気孔２３への吸気は側方窓３０と通じる吸気室３２を通して行われ、排気は排気孔２４から排気室３３に放出され、それから排気開口部３４を通して大気に放出される。 2 and 3, the windbreak device 20 according to the present invention is applied to an ultra-compact combustion device similar to that shown in FIG. The combustion apparatus includes a combustor body 21, and a case lid 22 covering the combustor body 21 has openings 25 and 26 aligned with the intake holes 23 and the exhaust holes 24 of the combustor body 21, respectively. The windproof device 20 includes a windproof box 27 that has a size that covers the intake hole 23 and the exhaust hole 24 and is fixedly attached to the case lid 22. The case lid 22 and the windproof box 27 are preferably integrally formed of plastic. The windproof box 27 has an enclosure 28 and an intake chamber 32 and an exhaust chamber 33 that are isolated from each other by a partition wall 31. Side windows 30 communicating with the intake chamber 32 are formed in the left and right side wall portions 29 and 29. Further, the windproof box 27 is provided with an exhaust opening 34 for exhausting the combustion exhaust from the exhaust hole 24 to the atmosphere through the exhaust chamber 33 on the front surface thereof. Thus, intake to the intake hole 23 is performed through the intake chamber 32 communicating with the side window 30, and exhaust is discharged from the exhaust hole 24 to the exhaust chamber 33 and then discharged to the atmosphere through the exhaust opening 34.
　排気開口部３４が正面から風を受けるのを防止するために、防風ボックス２７は、排気開口部３４を覆ってしかも排気の通過を可能にするため排気開口部から間隔を隔てて設けられた防風板３５を具える。より具体的には、防風板３５は、その４角に配置された支持ボスト３６によって防風ボックス２７の表面から支持される。 In order to prevent the exhaust opening 34 from receiving wind from the front, the windproof box 27 covers the exhaust opening 34 and is spaced from the exhaust opening to allow passage of the exhaust. A plate 35 is provided. More specifically, the windbreak plate 35 is supported from the surface of the windbreak box 27 by the support posts 36 arranged at the four corners.
　図２及び３でわかるように、風が斜め側方から側方窓に３０に入り込むのを防止するために、防風ボックス２７には、その前面側縁から側方に張り出した庇３７、３７が形成されるのが好ましい。側方窓３０の配置や大きさの工夫次第では、風の影響が吸気に及ばないようにすることも可能であるから、その場合には、庇を省き防風ボックスの囲い壁の左右側壁部分に設けられた側方窓をむき出しにしてもよいことは明らかである。また、強風が側方窓３０を通して吸気室３２に侵入して風圧が吸気作用に及ぼす影響を防止するために、ケース蓋２２には、風を遮るに充分な微細目のメッシュ（金網）３８が側方窓３０を覆って接着固定されるのがよい。また、強風が、防風ボックス２７の前面と防風板３５との間の隙間から排気開口部３４を通して排気室３３に侵入して排気作用に悪影響を及ぼさないようにするために、前記隙間の周りにこれを覆って微細目のメッシュ（金網）３８’が設けられるのがよい。 As can be seen in FIGS. 2 and 3, in order to prevent the wind from entering the side window 30 from an oblique side, the windproof box 27 has ridges 37, 37 projecting laterally from the front side edge thereof. Preferably it is formed. Depending on the arrangement and size of the side windows 30, it is possible to prevent the influence of the wind from affecting the intake air. Obviously, the provided side windows may be exposed. Further, in order to prevent the strong wind from entering the intake chamber 32 through the side window 30 and the influence of the wind pressure on the intake action, the case lid 22 has a fine mesh (metal mesh) 38 sufficient to block the wind. It is preferable that the side window 30 is covered and fixed. Further, in order to prevent strong winds from entering the exhaust chamber 33 through the exhaust opening 34 from the gap between the front surface of the windproof box 27 and the windbreak plate 35 and adversely affecting the exhaust action, A fine mesh (metal mesh) 38 ′ may be provided to cover this.
　図４乃至６は、本発明による防風ボックス２７の他の実施形態を示す。この防風ボックス２７は、排気室３３が、排気孔２４に整合して位置する開口部２６から排気開口部３４まで延びる排気ダクト３９として構成されている点を除いて図２及び３に示す実施形態の防風ボックスと実質的に同じである。かくして、排気ダクト３９は吸気室３２から隔絶され、排気孔からの燃焼排気を排気開口部を通して大気に放出する。 4 to 6 show other embodiments of the windproof box 27 according to the present invention. The windproof box 27 is an embodiment shown in FIGS. 2 and 3 except that the exhaust chamber 33 is configured as an exhaust duct 39 extending from the opening 26 positioned in alignment with the exhaust hole 24 to the exhaust opening 34. It is substantially the same as the windproof box. Thus, the exhaust duct 39 is isolated from the intake chamber 32, and the combustion exhaust from the exhaust hole is released to the atmosphere through the exhaust opening.
　本発明による防風装置の構成では、燃焼装置の吸気孔と排気孔を共通の防風ボックスで覆っているから、吸気及び排気は真上からの風の影響を受けることがほとんどなく、また吸気室と排気室とが互いに隔絶されているから、排気が吸気孔に吸い込まれることがなく、したがって、混合気中の酸素量が絶えず適正に維持されるから、燃焼室での燃焼火炎の立ち消えは決して起こらない。また、空気を吸い込むための窓と燃焼排気を大気に放出するための排気開口部の向きを互いに異なる構成としたため、排気の吸気孔への吸い込み防止は一層高められる。 In the configuration of the windproof device according to the present invention, the intake and exhaust holes of the combustion device are covered with a common windproof box, so that the intake and exhaust are hardly affected by the wind from directly above, and the intake chamber and Since the exhaust chamber is isolated from each other, the exhaust gas is not sucked into the intake port, and therefore the amount of oxygen in the air-fuel mixture is constantly maintained properly, so that the combustion flame in the combustion chamber never disappears. Absent. Further, since the direction of the window for sucking air and the direction of the exhaust opening for discharging the combustion exhaust to the atmosphere are different from each other, the prevention of the suction of the exhaust into the intake hole is further enhanced.
