Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial application]

本考案は消火時の臭気の低減を図った灯油等を燃料とする温風暖房器の制御回 路に関するものである。 The present invention relates to a control circuit for a hot air heater that uses kerosene or the like as a fuel to reduce odors when extinguishing a fire.

【0002】[0002]

【従来の技術】[Prior Art]

従来、温風暖房器の消火時の臭気の低減の目的で消火操作をした場合に、その 時点の燃焼量からまず燃焼量を最低に低下させ、一定時間燃焼させ、その後停止 させる。又、対流ファンを燃焼停止後一定時間停止させた後、再度一定時間回転 させるものがあった。(例えば実開平1−88144号公報) これは、燃焼装置の気化部に残留し出て来る未燃ガスを少なくし、臭気の低減 をはかるものであった。 Conventionally, when a fire extinguishing operation is performed for the purpose of reducing odor when extinguishing a warm air heater, the combustion amount is first reduced to the minimum from the combustion amount at that time, burned for a certain period of time, and then stopped. Further, there is a system in which the convection fan is stopped for a certain time after the combustion is stopped, and then is rotated again for a certain time. (For example, Japanese Utility Model Laid-Open No. 1-88144) This is intended to reduce odor by reducing unburned gas remaining in the vaporization section of the combustion device.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記実開平1−88144のような例では、燃焼中において、消火操作をして から再び運転モードにした場合に、燃焼量を最低に低下させ一定時間燃焼後、燃 焼停止し、対流ファンを一定時間停止させた後、再度一定時間回転後に再運転と するものであった。従って誤って切りボタンを押して消化モードとしてしまって から、再び運転モードに戻した場合に再運転までに時間がかかり、使い勝手が悪 く、又、切、入で再運転がすぐできるものにおいては対流ファンが一旦停止する ことで何度も切、入操作をすると、器体の温度が上昇するという問題があった。 In the case of the above-mentioned actual Kaihei 1-88144, when the extinguishing operation is performed during combustion and then the operation mode is resumed, the combustion amount is reduced to the minimum and after a certain period of combustion, the combustion is stopped and the convection fan is turned on. After stopping for a certain period of time, it was restarted after rotating again for a certain period of time. Therefore, if you press the cut button accidentally to switch to the extinguishing mode and then return to the operating mode again, it will take some time before restarting, and it will not be easy to use. There is a problem that the temperature of the body rises when the fan is turned off and then turned on and off repeatedly.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記欠点を除くためになされたもので、燃料を送る電磁ポンプと、電 磁ポンプから送られた燃料を気化させて燃焼させる燃焼装置と、この燃焼装置に て発生する熱排気を室内に強制的に放出する対流ファンと、これらを制御する制 御手段とを具備し、燃焼中消火操作をした時点で一定時間燃焼後消化モードとし 、燃焼停止後対流ファンを一定時間運転させポストパージをする温風暖房器の制 御回路において、制御手段は燃焼中の消火操作で一定時間燃焼中に再運転操作を した場合、消化モードをキャンセルして消火操作以前の燃焼モードに戻り燃焼継 続し、又一定時間経過し電磁ポンプ停止後の再運転では対流ファンを一定時間運 転させるポストパージ終了後再運転モードとするものとした。 The present invention has been made in order to eliminate the above-mentioned drawbacks. An electromagnetic pump for sending fuel, a combustion device for vaporizing and burning the fuel sent from the electromagnetic pump, and a heat exhaust gas generated by this combustion device are discharged indoors. It is equipped with a convection fan that forcibly discharges it into the combustion chamber and a control means that controls these.When the fire is extinguished during combustion, a post-combustion extinguishing mode is set for a certain period of time, and the convection fan is operated for a certain period of time after the combustion is stopped. In the control circuit of the warm air heater, the control means cancels the extinguishing mode and returns to the combustion mode before the fire extinguishing operation when the fire extinguishing operation during combustion restarts the operation for a certain period of time. After restarting after the electromagnetic pump has stopped for a certain period of time, the convection fan should be operated for a certain period of time after the post-purge operation is completed.

【0005】[0005]

【作用】[Action]

上記のように構成したことにより、消化モードの最小燃焼量での再運転では消 火することなく燃焼継続し、電磁ポンプ停止後の再運転ではポストパージ終了ま で消化モードとし、消化時の臭気を低減し、又、本体の表面温度を上昇させるこ となく消火し再運転に移行する作用をする。 With the above configuration, the combustion continues without extinguishing when restarting at the minimum combustion amount in the digestion mode, and when restarting after the electromagnetic pump is stopped, the digestion mode is set until post-purging ends, and the odor during digestion is eliminated. It also has the effect of extinguishing the fire and shifting to restarting without increasing the surface temperature of the main body.

【0007】 図において、1は燃料を送る電磁ポンプ、2は電磁ポンプ1から送られた燃料 を気化させて燃焼させる燃焼装置、3は燃焼装置2にて発生する熱排気を室内に 送風する対流ファン、4は電磁ポンプ1と燃焼装置2の電気部品及び対流ファン 3に接続してそれらを制御する制御手段である。In the figure, 1 is an electromagnetic pump that sends fuel, 2 is a combustion device that vaporizes and burns the fuel sent from the electromagnetic pump 1, and 3 is convection that blows the heat exhaust generated in the combustion device 2 into the room. The fans 4 are control means that are connected to the electric components of the electromagnetic pump 1 and the combustion device 2 and the convection fan 3 to control them.

【0008】 燃焼装置2は内部に気化ヒータ5、気化器サーミスタ6、ソウジ棒7等を有す る気化器8にソウジ棒7を駆動するソレノイド9と、ノズル10を取付け、ノズ ル10の先にバーナ11を設け、バーナ11の火炎部にプラグ12を配した点火 器13をバーナ11から離れた位置に設けた構成となっている。制御手段4は制 御用マイコン等を有する制御回路14に接続した運転SW15、切SW16、バ ーナ11の火炎部に設けたフレームロッド17から入力を受けるフレーム検出手 段18、室温設定手段19、サーミスタ等からなる室温検知手段20等で構成さ れている。制御回路14の制御用マイコンは、燃焼中に消火操作をした場合に、 電磁ポンプ1の送油量をその時点の燃焼モード(例えば速暖=送油量9、強=8 、9、中=6、5、弱=4、3、微=2、1の中の強=送油量8で燃焼している のであれば、8)の送油量から最低の燃焼モード(微弱1)に低下させ、各燃焼 モードに応じた時間だけ燃焼させた後に消火モード(送油量0)とするとともに 、対流ファン3を各燃焼モードに応じた時間だけ停止させた後、再度一定時間回 転させるようプログラムしてある。The combustion device 2 has a carburetor 8 having a vaporization heater 5, a carburetor thermistor 6, a Sojiji rod 7 and the like inside, a solenoid 9 for driving the Sojiji rod 7 and a nozzle 10, and a tip of the nozzle 10. A burner 11 is provided in the burner 11, and an igniter 13 in which a plug 12 is arranged in a flame portion of the burner 11 is provided at a position apart from the burner 11. The control means 4 is an operation SW 15 connected to a control circuit 14 having a control microcomputer or the like, a disconnection SW 16, a frame detection means 18 for receiving an input from a frame rod 17 provided in the flame portion of the burner 11, a room temperature setting means 19, It is composed of a room temperature detecting means 20 including a thermistor and the like. When the fire extinguishing operation is performed during combustion, the control microcomputer of the control circuit 14 sets the oil feed amount of the electromagnetic pump 1 to the combustion mode at that time (for example, fast warm = oil feed amount 9, strong = 8, 9, 9, medium = 6,5, Weak = 4,3, Fine = 2, Strong among 1 = If the combustion is done with the oil feed amount 8, the oil feed amount from 8) drops to the lowest combustion mode (weak 1) Then, after burning for a time corresponding to each combustion mode, the fire extinguishing mode (oil feeding amount 0) is set, and the convection fan 3 is stopped for a time corresponding to each combustion mode and then rotated again for a fixed time. It is programmed.

【0009】 上記構成からなる本実施例の動作について説明する。The operation of this embodiment having the above configuration will be described.

【0010】 運転SW15をONすると、気化器ヒータ5に通電され加熱が始まる。気化器 8が一定温度に上昇すると、気化器サーミスタ6が制御回路14に入力を与え、 ソレノイド9がONして気化器のノズル10の孔をソウジ棒が閉じる。さらに気 化器8の温度が上昇すると、点火指令4秒前に電磁ポンプ1が作動する。点火指 令と同時にソレノイド9がOFFし、ノズル10のソウジ棒7が解除され、ノズ ル10より気化ガスがバーナ11に送られ、点火器13がONし、プラグ12が スパークし、燃焼が始まる。対流ファン3は点火指令より5秒遅延して回転し送 風する。フレームロッド17を介してフレーム検出手段18がフレームを検出し 、YESの場合は定常燃焼状態となる。運転中は室温に応じて燃焼モードが変わ る。燃焼モードは送油量9〜1まで変化し、9が速暖、8、7が強、6、5が中 、4、3が弱、2、1が微の表示となっている。When the operation SW 15 is turned on, the carburetor heater 5 is energized to start heating. When the carburetor 8 rises to a constant temperature, the carburetor thermistor 6 gives an input to the control circuit 14, the solenoid 9 is turned on, and the Soji bar closes the hole of the nozzle 10 of the carburetor. When the temperature of the carburetor 8 further rises, the electromagnetic pump 1 operates 4 seconds before the ignition command. Simultaneously with the ignition command, the solenoid 9 is turned off, the Suji bar 7 of the nozzle 10 is released, vaporized gas is sent from the nozzle 10 to the burner 11, the igniter 13 is turned on, the plug 12 is sparked, and combustion starts. .. The convection fan 3 rotates and blows with a delay of 5 seconds from the ignition command. The flame detection means 18 detects the flame via the flame rod 17, and when YES, the steady combustion state is established. During operation, the combustion mode changes depending on the room temperature. The combustion mode changes from 9 to 1 for the amount of oil fed, with 9 being quick warming, 8 and 7 being strong, 6, 5 being medium, 4 and 3 being weak, and 2 and 1 being fine.

【0011】 消火時に切SW16をOFFすると、いずれの燃焼モード9〜1からも必ず熱 量が一番低い燃焼モード1に移り、各燃焼モードに応じた時間(本例では9、8 、7は5秒間、6、5は4秒間、4、3は3秒間、2、1は2秒間)燃焼し、気 化ガスの発生が最小となってから停止するものである。燃焼停止時は電磁ポンプ 1もOFFするものである。ソレノイド9は燃焼停止後2秒でONし、ノズル1 0の噴出をソウジ棒7により閉止する。When the OFF SW 16 is turned off during extinguishing the fire, the combustion mode 1 having the lowest calorific value is always moved from any of the combustion modes 9 to 1, and the time corresponding to each combustion mode (in this example, 9, 8, 7 is It burns for 5 seconds, 6 and 5 for 4 seconds, 4 and 3 for 3 seconds, 2 and 1 for 2 seconds, and stops after the generation of vaporized gas is minimized. When the combustion is stopped, the electromagnetic pump 1 is also turned off. The solenoid 9 is turned on 2 seconds after the combustion is stopped, and the ejection of the nozzle 10 is closed by the Soji bar 7.

【0012】 また対流ファン3は、燃焼停止後の切SW17のOFF時の燃焼モードに応じ た時間停止後(本例では9、8、7は16秒間、6、5は14秒間、4、3は1 2秒間、2、1は10秒間)停止させ、バーナ11から出て来る気化ガスを自然 対流で放出した後、再度一定時間(本例では40秒間)回転し、温風暖房器を冷 却してから停止する。Further, the convection fan 3 is stopped for a period of time corresponding to the combustion mode when the switch SW 17 is turned off after the combustion is stopped (in this example, 9, 8 and 7 are 16 seconds, 6 and 5 are 14 seconds, 4 and 3). For 12 seconds, 2, 1 for 10 seconds), and after releasing the vaporized gas coming out of the burner 11 by natural convection, rotate it again for a fixed time (40 seconds in this example) to cool the hot air heater. Stop and then stop.

【0013】 次に切SW16をOFFした後、再び運転SW15をONすると、消化モード の燃焼モード1の燃焼かどうかを判断し、燃焼モード1の場合は、切SW16入 力前の燃焼モードに戻る。又、燃焼モード1にての所定時間が経過して電磁ポン プ1もOFF後は、対流ファン3を停止しその後一定時間運転させるポストパー ジ終了後に再運転モードとする。Next, when the OFF SW 16 is turned OFF and then the operation SW 15 is turned ON again, it is determined whether or not the combustion is in the combustion mode 1 of the extinguishing mode. In the case of the combustion mode 1, the operation returns to the combustion mode before the OFF SW 16 is input. .. Further, after the predetermined time in the combustion mode 1 has passed and the electromagnetic pump 1 is also turned off, the convection fan 3 is stopped, and after that, the operation is continued for a certain period of time.

【考案の効果】[Effect of the device]

以上により本考案によれば、制御手段を、燃焼中の消火操作で一定時間燃焼中 に再運転操作をした場合、以前の燃焼モードに戻り燃焼継続するものとしたから 、再運転に時間がかかるという使い勝手の悪さを解消し、又一定時間経過し電磁 ポンプ停止後の再運転では対流ファンを一定時間運転させるポストパージ終了後 再運転モードとするものとしたから、停止、再運転時の臭気を低減し、器体表面 の温度上昇を防止する等、快適性、安全性を向上する効果がある。 As described above, according to the present invention, when the control means is re-operated during the combustion for a certain period of time during the extinguishing operation during combustion, the control means returns to the previous combustion mode and continues combustion, so it takes time to restart. In addition to eliminating the inconvenience, the restart of the electromagnetic pump after a certain period of time has been restarted after the convection fan has been operated for a certain period of time. It has the effect of improving comfort and safety by reducing the temperature and preventing the temperature rise on the surface of the body.
