Description
本発明は、暖房機本体内に、バーナと、バーナから噴出する混合気を燃焼させる燃焼筐と、温風ファンとを備え、暖房機本体には空気取入れ口と温風吹出し口とが開設され、空気取入れ口から流入する空気と燃焼筐の上端の排気口から排出される燃焼排ガスとが温風ファンに吸込まれて温風吹出し口に送風されるようにした温風暖房機に関する。 The present invention is provided with a burner, a combustion casing for burning an air-fuel mixture ejected from the burner, and a warm air fan in the heater body, and an air intake port and a warm air outlet port are established in the heater body. The present invention relates to a warm air heater in which air flowing in from an air intake port and combustion exhaust gas discharged from an exhaust port at the upper end of a combustion housing are sucked into a warm air fan and blown to a warm air outlet.
従来、この種の温風暖房機として、温風ファンを燃焼筐の下方に配置すると共に、暖房機本体内に、燃焼筐を前方から上方に亘って囲う隔壁を設けて、隔壁と燃焼筐との間に、空気取入れ口から流入した空気と燃焼筐の上端の排気口から排出される燃焼排ガスとを混合して温風ファンの吸込み側に導く通気路を画成したものは知られている（例えば、特許文献１参照）。また、このものでは、空気取入れ口から流入した空気の一部が暖房機本体の前面と隔壁との間の隙間を経由して温風ファンに吸込まれるようにしている。これにより、暖房機本体の前面を空冷できる。 Conventionally, as a warm air heater of this type, a hot air fan is disposed below the combustion housing, and a partition wall is provided in the heater body so as to surround the combustion housing from the front to the top. It is known that an air passage is defined between the air flowing in from the air intake port and the combustion exhaust gas discharged from the exhaust port at the upper end of the combustion housing and leading to the intake side of the hot air fan (For example, refer to Patent Document 1). Moreover, in this thing, a part of air which flowed in from the air intake port is sucked into a warm air fan via the clearance gap between the front surface of a heater main body, and a partition. Thereby, the front surface of a heater main body can be air-cooled.
ところで、暖房機本体の前面側から燃焼筐の内部を目視可能として、燃焼筐内に擬似薪を収納することにより暖炉風の感じを得られるようにすることが望まれる場合がある。上記従来例の温風暖房機を暖炉風のものにするには、暖房機本体の前面と隔壁と燃焼筐の前面とに、夫々燃焼筐の内部を目視可能にするための窓部を設けて、これら各窓部にガラス板を装着する必要がある。そのため、ガラス板が３重に配置されることになり、構造が複雑になってコストが高くなる。 By the way, it may be desired to make the inside of the combustion casing visible from the front side of the main body of the heater so that a fireplace-like feeling can be obtained by storing the simulated firewood in the combustion casing. In order to make the warm air heater of the conventional example into a fireplace-like one, a window portion is provided on the front surface of the main body of the heater, the partition wall, and the front surface of the combustion housing to make the inside of the combustion housing visible. It is necessary to attach a glass plate to each of these windows. For this reason, the glass plates are arranged in triplicate, the structure becomes complicated, and the cost increases.
尚、隔壁を省略し、燃焼筐の上端の排気口から排出される燃焼排ガスと空気取入れ口から流入する空気とが暖房機本体の前面の窓部に装着した窓ガラスと燃焼筐の前面の窓部に装着したガラス板との間の隙間を経由して燃焼筐の下方の温風ファンに吸込まれるようにすることも考えられる。然し、これでは、暖房機本体の前面の窓部に装着するガラス板が高温になり、このガラス板に手を触れたときに熱い思いをさせる虞がある。
本発明は、以上の点に鑑み、暖炉風の感じを得られるようにした構造が簡単で低コストの温風暖房機を提供することをその課題としている。 In view of the above points, an object of the present invention is to provide a warm air heater having a simple structure and a low cost so that a fireplace-like feeling can be obtained.
上記課題を解決するために、本発明は、暖房機本体内に、バーナと、バーナから噴出する混合気を燃焼させる燃焼筐と、温風ファンとを備え、暖房機本体には空気取入れ口と温風吹出し口とが開設され、空気取入れ口から流入する空気と燃焼筐の上面の一部に開設された排気口から排出される燃焼排ガスとが温風ファンに吸込まれて温風吹出し口に送風されるようにした温風暖房機において、暖房機本体の前面と燃焼筐の前面とに、燃焼筐の内部を目視可能とするため、夫々ガラス板を装着した窓部が設けられて、燃焼筐内に擬似薪が収納され、温風ファンは燃焼筐の上方に配置され、暖房機本体の前面の窓部に装着したガラス板と燃焼筐の前面の窓部に装着したガラス板との間に空気を上昇方向に案内するための隙間を形成し、該隙間を上方に延長すべく前記燃焼筐前面上部に起立して暖房機本体の前面の窓部に装着したガラス板と対向する仕切り板を設け、前記隙間に沿って上昇した空気が暖房機本体内方に向うときに、前記仕切り板の上部を越えた前記空気を下方に屈曲させる屈曲流路を形成し、空気取入れ口から流入する空気の一部が、燃焼筐の下方から暖房機本体の前面の窓部に装着したガラス板と燃焼筐の前面の窓部に装着したガラス板との間の隙間の下端に入り、更に両ガラス板間の隙間の上端から仕切り板を越えて屈曲流路を通過し、燃焼筐の上部に沿って暖房機本体内方に向った後に前記温風ファンに吸込まれるようにし、前記隙間から前記温風ファンに向かう空気は、少なくとも前記屈曲流路を通過した後に、前記排気口から排出される燃焼排ガスと合流することを特徴とする。 In order to solve the above-described problems, the present invention includes a burner, a combustion casing for burning an air-fuel mixture ejected from the burner, and a hot air fan in the heater body, and the heater body includes an air intake port. The hot air outlet is opened, and the air flowing in from the air intake and the combustion exhaust gas discharged from the exhaust opening provided in a part of the upper surface of the combustion housing are sucked into the hot air fan and are sent to the hot air outlet. In the hot air heater that is designed to blow air, the front of the main body of the heater and the front of the combustion housing are provided with windows that are each fitted with a glass plate in order to make the inside of the combustion housing visible. A simulated soot is housed in the housing, and the hot air fan is disposed above the combustion housing. Between the glass plate attached to the front window portion of the heater body and the glass plate attached to the front window portion of the combustion housing. A gap for guiding air in the upward direction is formed on the A partition plate that stands up at the upper front of the combustion housing and faces the glass plate mounted on the front window of the heater body is provided so that the air rising along the gap faces inward of the heater body. Sometimes, a bent flow path is formed that bends the air above the upper part of the partition plate downward, and a part of the air flowing in from the air intake port is opened from the lower part of the combustion housing to the front window part of the heater body. Enters the lower end of the gap between the glass plate attached to the glass plate attached to the front window portion of the combustion housing, and further passes through the bent flow path beyond the partition plate from the upper end of the gap between the two glass plates , The hot air fan is sucked into the hot air fan after being directed inward of the heater main body along the upper part of the combustion housing, and the air flowing from the gap toward the hot air fan passes through the bent flow path at least, It merges with the combustion exhaust gas discharged from the exhaust port And wherein the door.
本発明によれば、温風ファンが燃焼筐の上方に配置されるため、暖房機本体の前面と燃焼筐の前面との間に、燃焼筐の上端の排気口から排出される燃焼排ガスを温風ファンに導くための上記従来例の隔壁のような部材を配置せずに済む。従って、ガラス板は暖房機本体の前面の窓部と燃焼筐の前面の窓部とに装着するだけで良く、ガラス板を３重に配置するものに比し構造が簡単になってコストが安くなる。更に、暖房機本体の前面の窓部に装着したガラス板と燃焼筐の前面の窓部に装着したガラス板との間の隙間に空気が流れるため、暖房機本体の前面の窓部に装着したガラス板が空冷され、このガラス板に手を触れても熱い思いをさせない。 According to the present invention, since the hot air fan is disposed above the combustion housing, the combustion exhaust gas discharged from the exhaust port at the upper end of the combustion housing is warmed between the front surface of the heater body and the front surface of the combustion housing. It is not necessary to arrange a member such as the partition wall of the above-described conventional example for guiding to the wind fan. Therefore, the glass plate only needs to be attached to the front window portion of the heater body and the front window portion of the combustion housing, and the structure is simpler and the cost is lower than that in which three glass plates are arranged. Become. Furthermore, since air flows through the gap between the glass plate attached to the front window portion of the heater body and the glass plate attached to the front window portion of the combustion housing, it is attached to the front window portion of the heater body. The glass plate is air-cooled, and even if you touch this glass plate, you will not feel hot.
尚、温風ファンを燃焼筐の下方に配置する場合は、燃焼筐の配置位置が高くなって、暖房機の全高内の比較的高い位置に擬似薪が配置されることになる。本物の暖炉では薪を底部に置くため、違和感のあるデザインになってしまう。これに対し、本発明では、温風ファンを燃焼筐の上方に配置することで、燃焼筐の配置位置を低くして、暖房機の全高内の比較的低い位置に擬似薪を配置することができ、暖炉らしい感じを出すことができる。 When the hot air fan is arranged below the combustion housing, the arrangement position of the combustion housing becomes high, and the pseudo soot is arranged at a relatively high position within the overall height of the heater. In a real fireplace, the firewood is placed at the bottom, which makes the design uncomfortable. On the other hand, in the present invention, by arranging the hot air fan above the combustion housing, the placement position of the combustion housing can be lowered, and the dummy soot can be disposed at a relatively low position within the overall height of the heater. Yes, you can feel like a fireplace.
また、本発明においては、空気取入れ口から流入する空気の一部が暖房機本体の後面と燃焼筐の後面との間の隙間を経由して温風ファンに吸込まれるようにすることが望ましい。これによれば、暖房機本体の後面の過熱も防止できる。 Further, in the present invention, it is desirable that a part of the air flowing from the air intake port is sucked into the hot air fan via a gap between the rear surface of the heater main body and the rear surface of the combustion housing. . According to this, overheating of the rear surface of the heater body can also be prevented.
図１を参照して、１は温風暖房機の暖房機本体を示している。暖房機本体１内には、下部のバーナ２と、バーナ２の上方に位置する燃焼筐３と、燃焼筐３の上方に位置する温風ファン４とが配置されている。 Referring to FIG. 1, reference numeral 1 denotes a heater body of a hot air heater. In the heater main body 1, a lower burner 2, a combustion casing 3 positioned above the burner 2, and a hot air fan 4 positioned above the combustion casing 3 are arranged.
暖房機本体１には、その後面に上下複数の空気取入れ口５が開設され、また、その前面上部に温風吹出し口６が開設されている。温風吹出し口６には温風の吹出し方向を下向きにするルーバー６ａが装着され、また、暖房機本体１の後面の外側には図示省略したフィルタが装着される。 A plurality of upper and lower air intakes 5 are opened on the rear surface of the main body 1 of the heater, and a hot air outlet 6 is opened on the upper part of the front surface. A louver 6a is attached to the hot air outlet 6 so that the direction of the hot air is directed downward, and a filter (not shown) is attached to the outside of the rear surface of the heater body 1.
暖房機本体１の前面と燃焼筐３の前面とには、燃焼筐３の内部を目視可能とするために、夫々ガラス板７ａ，８ａを装着した窓部７，８が設けられている。そして、燃焼筐３内に擬似薪９を収納し、暖炉風の感じが得られるようにしている。尚、本実施形態では、図２に示す如く、横方向に長手の保持枠１０を設けて、保持枠１０の前後に保持爪１０ａを介して前後一対の擬似薪９，９を取付けている。そして、保持枠１０を燃焼筐３の底面上に固定することで、擬似薪９，９を燃焼筐３内に収納している。
Window portions 7 and 8 fitted with glass plates 7a and 8a are provided on the front surface of the heater body 1 and the front surface of the combustion housing 3 in order to make the inside of the combustion housing 3 visible. Then, a pseudo urn 9 is housed in the combustion housing 3 so that a fireplace-like feeling can be obtained. In the present embodiment, as shown in FIG. 2, a
バーナ２は、多数の炎孔を有する燃焼プレート２ａを備えるプレート式バーナで構成されている。バーナ２に供給される混合気（燃料ガスと一次空気との混合ガス）は理論空燃比より燃料濃度が濃くなっている。また、燃焼プレート２ａの直上部の空間を囲う二次空気制限筒２ｂを設けて、燃焼プレート２ａの近傍で混合気が燃焼することを抑制している。そして、混合気が二次空気制限筒２ｂを介して燃焼筐３内の前後の擬似薪９，９間の空間に導入され、燃焼筐３の底面に設けられた給気部３ａからの二次空気の供給で混合気が燃焼筐３内でブンゼン燃焼するようにしている。これにより、前後の擬似薪９，９間から上方に立ち伸びる火炎が生成され、擬似薪９が燃えているような視覚的印象が与えられる。 The burner 2 is a plate-type burner including a combustion plate 2a having a large number of flame holes. The air-fuel mixture (mixed gas of fuel gas and primary air) supplied to the burner 2 has a fuel concentration higher than the stoichiometric air-fuel ratio. In addition, a secondary air restriction cylinder 2b that surrounds the space immediately above the combustion plate 2a is provided to prevent the air-fuel mixture from burning near the combustion plate 2a. Then, the air-fuel mixture is introduced into the space between the front and rear dummy rods 9 and 9 in the combustion housing 3 through the secondary air restriction cylinder 2b, and the secondary air from the air supply unit 3a provided on the bottom surface of the combustion housing 3 The air-fuel mixture is burned in the combustion housing 3 by supplying air. As a result, a flame extending upward from between the front and rear pseudo scissors 9 and 9 is generated, giving a visual impression that the spear 9 is burning.
温風ファン４は、図外のモータで回転駆動されるファン本体４ａと、ファン本体４ａを収納するファンケーシング４ｂとで構成されている。ファンケーシング４ｂの吹出し口４ｃは温風吹出し口６に接続され、ファンケーシング４ｂの吸込み口４ｄは燃焼筐３の上方位置で下向きに開口している。そして、燃焼筐３の上端の排気口３ｂをファンケーシング４ｂの吸込み口４ｄに臨ませている。 The hot air fan 4 includes a fan body 4a that is rotationally driven by a motor (not shown), and a fan casing 4b that houses the fan body 4a. The air outlet 4 c of the fan casing 4 b is connected to the hot air outlet 6, and the air inlet 4 d of the fan casing 4 b opens downward at a position above the combustion housing 3. The exhaust port 3b at the upper end of the combustion housing 3 faces the suction port 4d of the fan casing 4b.
また、ファンケーシング４ｂの吸込み口４ｄは、排気口３ｂに対向するだけでなくその前方及び後方に亘って広がっている。そして、暖房機本体１の前面の窓部７に装着したガラス板７ａと燃焼筐３の前面の窓部８に装着したガラス板８ａとの間の隙間を窓部７の上端から吸込み口４ｄの前端に達する導風板１１を介して吸込み口４ｄの前部に連通させている。更に、暖房機本体１の後面と燃焼筐３の後面との間の隙間を吸込み口４ｄの後部に連通させている。 Further, the suction port 4d of the fan casing 4b not only opposes the exhaust port 3b but also extends forward and rearward. And the clearance gap between the glass plate 7a with which the front window part 7 of the heater main body 1 was mounted | worn, and the glass plate 8a with which the front window part 8 of the combustion housing 3 was mounted | worn from the upper end of the window part 7 of the suction inlet 4d It communicates with the front part of the suction port 4d through the air guide plate 11 reaching the front end. Further, a gap between the rear surface of the heater body 1 and the rear surface of the combustion housing 3 is communicated with the rear portion of the suction port 4d.
温風ファン４のファン本体４ａを回転させると、空気取入れ口５から流入する空気の一部が暖房機本体１の後面と燃焼筐３の後面との間の隙間を経由して温風ファン４に吸込まれる。また、空気取入れ口５から流入する空気の一部は燃焼筐３の下方空間に回り込む。そして、燃焼筐３の下方空間に回り込んだ空気の一部は燃焼筐３の底面の給気部３ａから燃焼筐２内に吸込まれ、この空気を二次空気として燃焼筐２内での混合気の燃焼が行われて、燃焼排ガスが燃焼筐３の上端の排気口３ｂから温風ファン４に吸込まれる。また、燃焼筐３の下方空間に回り込んだ空気の一部は暖房機本体１の前面の窓部７に装着したガラス板７ａと燃焼筐３の前面の窓部８に装着したガラス板８ａとの間の隙間を経由して温風ファン４に吸込まれる。そして、燃焼排ガスと空気とが混合されて温風吹出し口６に送風される。図１には、空気の流れが白抜きの矢印で示され、燃焼排ガスの流れが黒塗りの矢印で示され、空気と燃焼排ガスとの混合後の温風の流れが白と黒に塗り分けた矢印で示されている。 When the fan main body 4 a of the hot air fan 4 is rotated, a part of the air flowing in from the air intake port 5 passes through a gap between the rear surface of the heater main body 1 and the rear surface of the combustion housing 3, and the hot air fan 4. Sucked into. Further, a part of the air flowing in from the air intake port 5 goes into the lower space of the combustion housing 3. A part of the air that has entered the space below the combustion housing 3 is sucked into the combustion housing 2 from the air supply portion 3a on the bottom surface of the combustion housing 3, and this air is used as secondary air to be mixed in the combustion housing 2. Combustion exhaust gas is sucked into the warm air fan 4 from the exhaust port 3 b at the upper end of the combustion housing 3. Further, a part of the air that has entered the space below the combustion housing 3 includes a glass plate 7 a attached to the window portion 7 on the front surface of the heater body 1 and a glass plate 8 a attached to the window portion 8 on the front surface of the combustion housing 3. The air is sucked into the hot air fan 4 via a gap between the two. Then, the combustion exhaust gas and air are mixed and blown to the hot air outlet 6. In FIG. 1, the flow of air is indicated by white arrows, the flow of combustion exhaust gas is indicated by black arrows, and the flow of warm air after mixing air and combustion exhaust gas is separately painted in white and black Indicated by an arrow.
ところで、燃焼筐３の下方に温風ファンを配置し、燃焼筐３の上端の排気口３ｂから排出される燃焼排ガスを暖房機本体１の前面の窓部７のガラス板７ａと燃焼筐３の前面の窓部８のガラス板８ａとの間の隙間を介して温風ファンに導くことが考えられる。然し、これでは暖房機本体１の前面の窓部７のガラス板７ａが高温になってしまう。ガラス板７ａの過熱を防止するには、暖房機本体１の前面と燃焼筐３の前面との間に隔壁を設けて、燃焼排ガスを隔壁と燃焼筐との間の隙間を介して下方の温風ファンに導くことが必要になる。この場合、燃焼筐３の内部を目視可能にするには、隔壁にも窓部を設けて、これにガラス板を装着することが必要になる。然し、これではガラス板が３重に配置されることになり、構造が複雑になってコストが高くなる。 By the way, a hot air fan is arranged below the combustion housing 3, and the combustion exhaust gas discharged from the exhaust port 3 b at the upper end of the combustion housing 3 is sent to the glass plate 7 a of the window 7 on the front surface of the heater body 1 and the combustion housing 3. It is conceivable to guide the hot air fan through a gap between the front window portion 8 and the glass plate 8a. However, in this case, the glass plate 7a of the window portion 7 on the front surface of the heater body 1 becomes high temperature. In order to prevent overheating of the glass plate 7a, a partition wall is provided between the front surface of the heater body 1 and the front surface of the combustion housing 3, and the combustion exhaust gas is heated to a lower temperature via a gap between the partition wall and the combustion housing. It is necessary to guide to the wind fan. In this case, in order to make the inside of the combustion housing 3 visible, it is necessary to provide a window on the partition wall and attach a glass plate to the window. However, in this case, the glass plates are arranged in triplicate, the structure becomes complicated, and the cost increases.
これに対し、本実施形態では、温風ファン４が燃焼筐３の上方に配置されるため、燃焼排ガスは燃焼筐３の上端の排気口３ｂからストレートに温風ファン４に吸込まれ、上記隔壁は不要になる。従って、暖房機本体１の前面の窓部７と燃焼筐３の前面の窓部８とにガラス板７ａ，８ａを装着するだけで良く、ガラス板を３重に配置するものに比し構造が簡単になってコストが安くなる。更に、暖房機本体１の前面の窓部７に装着したガラス板７ａと燃焼筐３の前面の窓部８に装着したガラス板８ａとの間の隙間に空気が流れるため、ガラス板７ａを空冷できる。また、本実施形態では、暖房機本体１の後面と燃焼筐３の後面との間の隙間にも空気が流れるため、暖房機本体１の後面の過熱も防止できる。 On the other hand, in this embodiment, since the warm air fan 4 is disposed above the combustion housing 3, the combustion exhaust gas is directly sucked into the warm air fan 4 from the exhaust port 3b at the upper end of the combustion housing 3, and the partition wall Is no longer needed. Therefore, it is only necessary to attach the glass plates 7a and 8a to the window portion 7 on the front surface of the heater body 1 and the window portion 8 on the front surface of the combustion housing 3, and the structure is compared with that in which the glass plates are arranged in a triple manner. Simplify and reduce costs. Furthermore, since air flows in the gap between the glass plate 7a attached to the front window portion 7 of the heater body 1 and the glass plate 8a attached to the front window portion 8 of the combustion housing 3, the glass plate 7a is air-cooled. it can. Moreover, in this embodiment, since air flows also into the clearance gap between the rear surface of the heater main body 1, and the rear surface of the combustion housing 3, overheating of the rear surface of the heater main body 1 can also be prevented.
更に、温風ファン４を燃焼筐３の上方に配置することで、燃焼筐３の配置位置を低くして、暖房機の全高内の比較的低い位置に擬似薪９を配置することができる。これにより、底部に薪を置く本物の暖炉に近い感じを出すことができる。 Furthermore, by disposing the warm air fan 4 above the combustion housing 3, the disposition position of the combustion housing 3 can be lowered, and the dummy rod 9 can be disposed at a relatively low position within the overall height of the heater. As a result, it is possible to give a feeling close to a real fireplace with a firewood on the bottom.
以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態では、燃焼筐３の下方にバーナ２を配置したが、燃焼筐３を下方に延長して、燃焼筐３内にバーナ２を収納することも可能である。また、上記実施形態では、バーナ２を燃焼プレート２ａを備えるプレート式バーナで構成しているが、バーナ２として燃焼プレートを具備しない通常のブンゼン式バーナを用いることも可能である。 As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above-described embodiment, the burner 2 is disposed below the combustion housing 3. However, the burner 2 can be housed in the combustion housing 3 by extending the combustion housing 3 downward. Moreover, in the said embodiment, although the burner 2 is comprised with the plate type burner provided with the combustion plate 2a, it is also possible to use the normal Bunsen type burner which does not comprise a combustion plate as the burner 2.
