It is conceivable to provide between the burner part in the main body of the apparatus and the pedestal to which the burner part is attached, but simply by providing the wind direction plate of Patent Document 2 below the burner part, However, there is a problem that the warm air blown out from the lower air outlet hits the floor surface in front of the device body and the floor surface becomes hot.
上記課題を解決するために、本発明の請求項1では、略箱状の器具本体と、該器具本体内に上部収納部と下部収納部とを形成するユニット取り付け板と、該器具本体を載置する置き台と、下部収納部に収納され燃料を燃焼する燃焼部と、上部収納部に収納され燃焼部で発生した高温の燃焼ガスが流入する熱交換器と、器具本体背面に設け上部収納部と下部収納部とに空気を送風する対流ファンと、器具本体の前面に設けた吹出口とを備えた温風暖房装置に於いて、前記置き台と燃焼部との間に風向板を設け、前記風向板の器具本体背面側に上方に向かって傾斜した空気案内片を形成すると共に、前記風向板の器具本体前面側に上方に向かって傾斜した温風案内片が形成され、前記器具本体の前面で風向板よりも上方に吹出口を設け、前記置き台と風向板の下面との間に冷風路を形成し、該冷風路を通過した空気が器具本体の前面の床面に向かって吹き出すための冷風吹き出し口を前面板下部と置き台との境目部分に形成し、前記冷風路は、器具本体の背面から前面に向かって下向きに傾斜して設けたものである。 In order to solve the above-mentioned problems, in claim 1 of the present invention, a substantially box-shaped instrument body, a unit mounting plate that forms an upper storage part and a lower storage part in the instrument body, and the instrument body are mounted. A cradle to be placed, a combustion part that is stored in the lower storage part and burns fuel, a heat exchanger that is stored in the upper storage part and into which high-temperature combustion gas generated in the combustion part flows, and an upper storage that is provided on the back of the instrument body In a warm air heating apparatus comprising a convection fan that blows air to the upper part and the lower storage part, and an air outlet provided on the front surface of the instrument body, a wind direction plate is provided between the cradle and the combustion part An air guide piece inclined upward on the instrument body rear side of the wind direction plate, and a warm air guide piece inclined upward on the instrument body front side of the wind direction plate, Provide a blower outlet above the wind direction plate on the front of the A cold air passage is formed between the front plate and the lower surface of the wind direction plate, and a cold air outlet is formed at the boundary between the lower portion of the front plate and the table so that the air passing through the cold air passage is blown out toward the floor surface on the front surface of the instrument body The cold air passage is provided so as to be inclined downward from the back surface of the instrument body to the front surface.
この発明の請求項1によれば、置き台と燃焼部との間に風向板を設け、前記風向板の器具本体背面側に上方に向かって傾斜した空気案内片を形成すると共に、前記風向板の器具本体前面側に方に向かって傾斜した温風案内片が形成され、前記器具本体の前面で風向板よりも上方に吹出口を設けたので、器具本体の背面に設けた対流ファンにより流入した空気の一部が燃焼部が収納される下部収納部内に流入し、下部収納部内に流入した空気は風向板の空気案内片により風向板の上部と下部の二手に分かれ、風向板の上部を流れる空気は、下部収納部に燃焼部の熱により高温になった空気が滞留しないように風向板の温風案内片に案内されて上向きに流れを変え、それにより風向板よりも上方に位置する器具本体の前面の下に設けられた吹出口よりスムーズに室内に放出されるので、燃焼部の燃焼による熱で下部収納部内が非常に高温になってしまうのを防止できるものである。 According to the first aspect of the present invention, an air guide plate is provided between the cradle and the combustion section, and an air guide piece inclined upward is formed on the instrument main body rear side of the wind guide plate, and the wind guide plate is provided. A warm air guide piece inclined toward the front side of the instrument body is formed, and a blower outlet is provided on the front side of the instrument body above the wind direction plate, so that it flows in by a convection fan provided on the back side of the instrument body. A part of the air flows into the lower storage part where the combustion part is stored, and the air flowing into the lower storage part is divided into two parts, the upper part and the lower part of the wind direction plate, by the air guide piece of the wind direction plate. The flowing air is guided by the warm air guide piece of the wind direction plate so that the air heated to the high temperature by the heat of the combustion portion does not stay in the lower housing portion, and changes the flow upward, thereby being positioned above the wind direction plate. Air outlet provided under the front of the instrument body Ri because it is smoothly released into the chamber, in which it is possible to prevent the lower housing portion by the heat from the combustion of the combustion section resulting in very hot.
また、風向板の温風案内片が器具本体前面側に向かって上向きに傾斜していることにより、風向板の上部を流れる空気が器具本体の前面の下に設けられた吹出口より吹き出す時に上向きに吹き出すので、器具本体の前面の下に設けられた吹出口より吹き出す温風を上向きの流れにし、それにより吹出口より吹き出される温風が器具本体前方の床面に当たって床面が高温になってしまうのを防止できるものである。In addition, the warm air guide piece of the wind direction plate is inclined upward toward the front side of the instrument body, so that the air flowing through the upper part of the wind direction plate is upward when blown out from the air outlet provided under the front surface of the instrument body. Therefore, the warm air blown out from the air outlet provided under the front of the appliance body flows upward, and the hot air blown out from the air outlet hits the floor surface in front of the appliance body and the floor surface becomes hot. Can be prevented.
また、置き台と風向板の下面との間に冷風路を形成し、該冷風路を通過した空気が器具本体の前面の床面に向かって吹き出すための冷風吹き出し口を前面板下部と置き台との境目部分に形成したので、風向板の下部を流れる空気は、置き台と風向板の下面との間に形成された冷風路を通過し、その冷風路を通過した空気が前面板下部と置き台との境目部分に形成された冷風吹き出し口から器具本体の前面の床面に向かって吹き出され、それにより器具本体の前面に設けられた吹出口より吹き出される温風が器具本体前方の床面に当たって床面が高温になってしまうのを防止できると共に、置き台が高温になるのを防止して置き台の下の床面の温度上昇を防止できるものである。In addition, a cold air passage is formed between the cradle and the lower surface of the wind direction plate, and a cold air outlet for blowing the air that has passed through the cold air passage toward the floor surface on the front surface of the instrument body is provided on the lower portion of the front plate and the cradle. The air flowing in the lower part of the wind direction plate passes through the cold air passage formed between the pedestal and the lower surface of the wind direction plate, and the air that has passed through the cold air passage is in contact with the lower part of the front plate. The warm air blown out from the cold air outlet formed at the boundary with the pedestal toward the floor surface on the front surface of the instrument body is blown out from the outlet provided on the front surface of the instrument body. It is possible to prevent the floor surface from reaching a high temperature by hitting the floor surface, and to prevent the cradle from becoming hot, thereby preventing an increase in the temperature of the floor surface under the cradle.
また、冷風路は、器具本体の背面から前面に向かって下向きに傾斜して設けたので、冷風路を通過した空気が冷風吹き出し口から器具本体の前面の床面に向かって確実に吹き出され、器具本体の前面に設けられた吹出口より吹き出される温風が器具本体前方の床面に当たって床面が高温になってしまうのを防止できるものである。In addition, since the cold air passage is inclined downward from the back surface of the instrument body toward the front surface, the air that has passed through the cold air passage is surely blown out from the cold air outlet to the floor surface of the front surface of the equipment body, It is possible to prevent the warm air blown from the air outlet provided on the front surface of the instrument body from hitting the floor surface in front of the instrument body and causing the floor surface to become hot.

56はユニット取り付け板で、上面に外筒16を取り付けると共に下面に燃焼部6を取り付け、器具本体1内に熱交換器20と外筒16が収納される上部収納部57と、燃焼部6が収納される下部収納部58を形成するものである。   Reference numeral 56 denotes a unit mounting plate. The outer cylinder 16 is attached to the upper surface and the combustion section 6 is attached to the lower face. The upper storage section 57 in which the heat exchanger 20 and the outer cylinder 16 are stored in the instrument body 1, and the combustion section 6 The lower storage part 58 to be stored is formed.
次に、この暖房装置における暖房運転について詳細を説明する。
まず、操作部2の運転ボタン32を操作すると気化ヒータ8に通電して気化筒9内を加熱し、ポットサーミスタ10が150℃以上を検知したら燃焼ファン19を所定の回転数で駆動させて燃焼空気を送風し、その後、ポットサーミスタ10が210℃以上を検知したら、電磁ポンプ7をONにして所定量の燃油を気化筒9内に噴射して気化させ、点火プラグ13に通電して火花電流を発生させることで着火する。
Next, details of the heating operation in the heating apparatus will be described.
First, when the operation button 32 of the operation unit 2 is operated, the vaporizing heater 8 is energized to heat the inside of the vaporizing cylinder 9, and when the pot thermistor 10 detects 150 ° C. or higher, the combustion fan 19 is driven at a predetermined rotational speed for combustion. After the air is blown and the pot thermistor 10 detects 210 ° C. or higher, the electromagnetic pump 7 is turned on to inject and vaporize a predetermined amount of fuel into the vaporizing cylinder 9, and the spark plug 13 is energized to generate a spark current. Ignite by generating.
着火後、フレームロッド14で検知される炎電流値が所定値以上であるか確認して着火が成功したか判断し、着火が成功していれば対流ファン21を駆動させて、暖房運転を開始し、燃焼で発生した燃焼ガスは、燃焼部6で完全燃焼しながら上昇して赤熱筒15を加熱して赤熱状態とした後、集熱部42を介して熱交換器20内を流通して給排気筒23から屋外へ排出され、そして器具本体1の背面に設けた対流ファン21を駆動させることで、器具本体1の背面から吸引された室内空気が熱交換器20外周及び外筒16を通り温風となって室内に放出されると共に、赤熱状態の赤熱筒15より輻射熱が透明の外筒16を通し反射板17で器具本体1の前方に反射され、輻射暖房を行うものである。   After ignition, it is determined whether the flame current value detected by the frame rod 14 is equal to or greater than a predetermined value to determine whether ignition is successful. If the ignition is successful, the convection fan 21 is driven to start heating operation. Then, the combustion gas generated by the combustion rises while completely burning in the combustion unit 6 and heats the red hot cylinder 15 to be in a red hot state, and then circulates in the heat exchanger 20 through the heat collecting unit 42. By driving a convection fan 21 that is discharged from the air supply / exhaust tube 23 to the outdoors and provided on the back surface of the instrument main body 1, the indoor air sucked from the back surface of the instrument main body 1 flows around the heat exchanger 20 and the outer cylinder 16. In addition to being discharged into the room as warm air, the radiant heat is reflected from the red hot tube 15 through the transparent outer tube 16 to the front of the instrument body 1 by the reflector 17 to perform radiant heating.
この時、器具本体1の背面に設けた対流ファン21により流入した空気は、その空気の一部が上部収納部57内に流入し、熱交換器20外周及び外筒16を通り温風となって器具本体1の前面の上下に設けられた吹出口4より室内に放出されると共に、その空気の他の一部が下部収納部58内に流入し、下部収納部58内に流入した空気は風向板50の空気案内片52により風向板50の上部と下部の二手に分かれ、風向板50の上部を流れる空気は、下部収納部58内に燃焼部6の熱により高温となった空気が滞留しないように風向板50の温風案内片53に案内されて上向きに流れを変え、それにより風向板50よりも上方に位置する器具本体1の前面の下に設けられた吹出口4よりスムーズに室内に放出されるので、燃焼部6が収納される下部収納部58の空間が狭くなっても燃焼部6の燃焼による熱でその空間内が非常に高温になってしまうのを防止できるものである。   At this time, part of the air that has flowed in by the convection fan 21 provided on the back surface of the instrument body 1 flows into the upper storage portion 57 and passes through the outer periphery of the heat exchanger 20 and the outer cylinder 16 to become hot air. The other part of the air flows into the lower storage part 58 and the air that has flowed into the lower storage part 58 is discharged into the room through the air outlets 4 provided at the top and bottom of the front surface of the instrument body 1. The air guide piece 52 of the wind direction plate 50 is divided into two parts, the upper part and the lower part of the wind direction plate 50, and the air flowing through the upper part of the wind direction plate 50 is retained in the lower storage part 58 due to the heat of the combustion part 6. The air flow is guided upward by the warm air guide piece 53 of the wind direction plate 50 so as to change the flow upward, and thereby smoother than the air outlet 4 provided below the front surface of the instrument body 1 located above the wind direction plate 50. Since it is discharged indoors, the combustion part 6 is stored. That that space be space of the lower housing portion 58 is narrowed due to the heat from the combustion of the combustion portion 6 are those which can prevent the very hot.
また、風向板50の温風案内片53が器具本体1前面側に向かって上向きに傾斜していることにより、風向板50の上部を流れる空気が器具本体1の前面の下に設けられた吹出口4より吹き出す時に上向きに吹き出すので、器具本体1の前面の下に設けられた吹出口4より吹き出す温風を上向きの流れにし、それにより吹出口4より吹き出される温風が器具本体1前方の床面に当たって床面が高温になってしまうのを防止できるものである。   Further, since the warm air guide piece 53 of the wind direction plate 50 is inclined upward toward the front surface side of the instrument body 1, the air flowing above the wind direction plate 50 is blown below the front surface of the instrument body 1. Since it blows upward when it blows out from the outlet 4, the warm air blown out from the blower outlet 4 provided under the front surface of the instrument body 1 is made to flow upward, whereby the warm air blown out from the blower outlet 4 is forward of the instrument body 1 It is possible to prevent the floor surface from getting hot when hitting the floor surface.
また、風向板50の下部を流れる空気は、置き台51と風向板50の下面との間に形成された冷風路54を通過し、その冷風路54を通過した空気が前面板5下部と置き台51との境目部分に形成された冷風吹き出し口55から器具本体1の前面の床面に向かって吹き出されるので、器具本体1の前面に設けられた吹出口4より吹き出される温風が器具本体1前方の床面に当たって床面が高温になってしまうのを防止できると共に、置き台51が高温になるのを防止して置き台51の下の床面の温度上昇を防止できるものである。   Further, the air flowing under the wind direction plate 50 passes through the cold air passage 54 formed between the cradle 51 and the lower surface of the air direction plate 50, and the air passing through the cold air passage 54 is placed with the lower portion of the front plate 5. Since the cold air blowing port 55 formed at the boundary with the base 51 is blown out toward the floor surface on the front surface of the appliance main body 1, the warm air blown out from the outlet 4 provided on the front surface of the appliance main body 1 is blown out. It is possible to prevent the floor surface from reaching a high temperature by hitting the floor surface in front of the appliance body 1 and to prevent the cradle 51 from becoming hot to prevent the temperature of the floor surface under the cradle 51 from rising. is there.
更に冷風路54は、器具本体1の背面から前面に向かって下向きに傾斜しているので、冷風路54を通過した空気が冷風吹き出し口55から器具本体1の前面の床面に向かって確実に吹き出され、器具本体1の前面に設けられた吹出口4より吹き出される温風が器具本体1前方の床面に当たって床面が高温になってしまうのを防止できるものである。   Furthermore, since the cold air passage 54 is inclined downward from the back surface of the appliance body 1 toward the front surface, the air that has passed through the cold air passage 54 is reliably transferred from the cold air outlet 55 toward the floor surface in front of the appliance body 1. It is possible to prevent the warm air blown out and blown out from the air outlet 4 provided on the front surface of the instrument body 1 from hitting the floor surface in front of the instrument body 1 and causing the floor surface to become hot.
又、この時、器具本体1の背面に設けた対流ファン21により流入した空気は、外筒16の両側に位置する熱交換器固定金具45の遮熱片49により、前方に向けて広がって設けられている反射板17に沿って器具本体1の前面から左右に広がって吹き出る空気よりも、遮熱片49により案内されて外筒16と遮熱片49との間を直進して器具本体1の前面から真っ直ぐに吹き出る空気が多く、器具本体1を側面方向と背面方向の三方が壁で囲われたマントルピース等に設置した場合でも、器具本体1の前面から吹き出た温風が側面方向の壁に向かって殆ど流れず、側面方向の壁が高温になってしまうのを防止できるものである。   At this time, the air flowing in by the convection fan 21 provided on the back surface of the instrument body 1 is provided to spread forward by the heat shield pieces 49 of the heat exchanger fixing bracket 45 located on both sides of the outer cylinder 16. Rather than the air that spreads from the front of the instrument body 1 to the left and right along the reflecting plate 17, the instrument body 1 is guided by the heat shield piece 49 and goes straight between the outer cylinder 16 and the heat shield piece 49. Even when the instrument body 1 is installed on a mantelpiece or the like that is surrounded by walls on the three sides of the side and back, the warm air blown from the front of the instrument body 1 It hardly prevents flow toward the wall, and the side wall can be prevented from becoming hot.
また、加熱されて赤熱状態となった赤熱筒15の熱は、熱交換器固定金具45の遮熱片49により遮られて反射板17を過熱せず、それにより器具本体1の側面板と反射板17とにより形成される空間内の温度が高温にならず、器具本体1の側面板と反射板17とにより形成される空間内に設けた基板からなる制御部41や他の電装部品も高温になって異常が発生するのを防止できるものである。   Further, the heat of the red-hot cylinder 15 that has been heated to a red-hot state is blocked by the heat-shielding piece 49 of the heat exchanger fixture 45 and does not overheat the reflector 17, thereby reflecting the side plate of the instrument body 1. The temperature in the space formed by the plate 17 does not become high, and the control unit 41 and other electrical components made of a substrate provided in the space formed by the side plate of the instrument body 1 and the reflector 17 also have a high temperature. It is possible to prevent abnormalities from occurring.
そして制御部41は、着火が成功して暖房運転を開始する時、操作部2の自動/手動ボタン35で自動か手動のどちらが設定されているか確認し、自動/手動ボタン35で自動が設定されていれば、上下ボタン34で設定された室内設定温度まで室温が上昇するように燃焼ファン19の回転数や電磁ポンプ7から気化筒9内に送る燃油量を調節して燃焼量を増減させ、対流ファン21の回転数を増減させて室内に送風する温風を調節するものであり、室内温度センサ31で検知される室温と設定された室内温度とを比較して最適な火力での暖房運転を行い、また、自動/手動ボタン35で手動が設定されていれば、上下ボタン34で設定された1灯から6灯までの火力に応じて燃焼ファン19の回転数と電磁ポンプ7から気化筒9内に送る燃油量を調節し、対流ファン21の回転数を調節して室内に送風する温風の強弱を変化させることで、使用者が設定した火力の暖房運転を行うものである。   When the ignition is successful and the heating operation is started, the control unit 41 checks whether the automatic / manual button 35 of the operation unit 2 is set to automatic or manual, and the automatic / manual button 35 sets automatic. If so, the rotational speed of the combustion fan 19 and the amount of fuel sent from the electromagnetic pump 7 into the vaporizing cylinder 9 are adjusted to increase or decrease the combustion amount so that the room temperature rises to the indoor set temperature set by the up / down button 34, The temperature of the convection fan 21 is increased or decreased to adjust the warm air blown into the room, and the room temperature detected by the room temperature sensor 31 is compared with the set room temperature for heating operation with the optimum heating power. If manual is set by the automatic / manual button 35, the rotational speed of the combustion fan 19 and the vaporizing cylinder from the electromagnetic pump 7 according to the heating power from 1 to 6 lights set by the up / down button 34 Fuel sent in 9 Adjusting the amount, by adjusting the rotational speed of the convection fan 21 to vary the intensity of hot air to be blown into the room, and performs heating operation of thermal power set by the user.
又、暖房運転が開始されると、対流ファン21からの空気の一部が器具本体1の側面板と反射板17とにより形成される空間に流入し、その流入した空気は前面側方板39に形成された複数のスリット40から、前面板5の吹出口4と前面側方板39との間に形成された凹部に向かって吹き出され、そのスリット40から吹き出る空気がエアカーテンとなり、器具本体1の側面方向へ流動する温風を前面方向へ案内するので、器具本体1の前面から吹き出た温風が側面方向の壁に向かって殆ど流れず、側面方向の壁が高温になってしまうのを更に防止できるものである。   When the heating operation is started, a part of the air from the convection fan 21 flows into the space formed by the side plate of the instrument body 1 and the reflecting plate 17, and the inflowed air is the front side plate 39. The plurality of slits 40 formed on the front plate 5 are blown out toward the recesses formed between the blower outlet 4 of the front plate 5 and the front side plate 39, and the air blown out from the slits 40 becomes an air curtain. Since the warm air flowing in the lateral direction of 1 is guided to the front direction, the warm air blown out from the front surface of the instrument body 1 hardly flows toward the lateral wall, and the lateral wall becomes hot. Can be further prevented.
