Description
【０００１】[0001]
この考案は、家庭用の給湯機，給湯機付風呂釜等に使用する噴霧量可変石油バ ーナーに関する。 The present invention relates to a spray amount variable oil burner used for household water heaters, bath kettles with water heaters, etc.

この考案に技術的に最も近い従来例として、第１の電磁式ポンプと、第２の電 磁式ポンプと、戻り形ノズルと、戻り形ノズルからの油戻管の途中に設けた油電 磁弁とを使用した、図３記載の油経路を有した噴霧量可変石油バーナーがある。 As a conventional example technically closest to this invention, a first electromagnetic pump, a second electromagnetic pump, a return nozzle, and an oil electromagnetic valve provided in the middle of an oil return pipe from the return nozzle. There is a variable spray oil burner with an oil path according to FIG.
【０００３】[0003]
しかしながら、このような従来例にあっては、ポンプ停止中に、油タンクの油 がそのヘッドによってノズル先端より漏れないようにするために、油戻管の途中 に油電磁弁を設け、停止中はこの電磁弁を閉める事によって、戻り形ノズルの油 戻路より油が逆流するのを防止するとともに、第１の電磁式ポンプ（以下「低圧 ポンプ」という）と、第２の電磁式ポンプ（以下「高圧ポンプ」という）の内部 にも、停止時にポンプの油吸入側と油吐出側とを遮断する弁を設けていたため、 ポンプ停止中には、低圧ポンプの油吐出側と、高圧ポンプの油吸入側とを連結す る油送管、及びこの油送管に連結される油電磁弁出口からの油戻管内の油は閉塞 された状態となり、この配管回りの温度が上昇すると管内油圧も異常に上昇し、 これにより次のバーナー着火時に所定の噴霧量を大幅に上回る油量を噴霧し、こ れにより黒煙を発生するという問題点があった。 However, in such a conventional example, in order to prevent the oil in the oil tank from leaking from the nozzle tip by the head when the pump is stopped, an oil solenoid valve is installed in the middle of the oil return pipe to stop the pump. By closing this solenoid valve, the oil is prevented from flowing backward from the oil return passage of the return type nozzle, and the first electromagnetic pump (hereinafter referred to as "low pressure pump") and the second electromagnetic pump ( A valve that shuts off the oil intake side and the oil discharge side of the pump at the time of stop was also provided inside the (high pressure pump). Therefore, while the pump is stopped, the oil discharge side of the low pressure pump and the high pressure pump The oil in the oil feed pipe that connects to the oil suction side and the oil in the oil return pipe from the outlet of the oil solenoid valve that is connected to this oil feed pipe becomes blocked, and if the temperature around this pipe rises, the oil pressure in the pipe also changes. It rises abnormally, which causes the next Sprayed with oil amount significantly above a predetermined spray amount when Na ignition, disadvantageously generate black smoke This ensures.

この考案は、このような従来の問題点に着目してなされたもので、低圧ポンプ の油吸入側と油吐出側とを連結する油バイパス管を設け、その途中に油電磁弁を 設けることにより、上記問題点を解決することを目的としている。 This invention was made in view of such conventional problems, and an oil bypass pipe that connects the oil suction side and the oil discharge side of the low-pressure pump is provided, and an oil solenoid valve is provided in the middle of the oil bypass pipe. The purpose is to solve the above problems.
【０００５】[0005]
以下、この考案の実施例を図面に基づいて説明する。図１は、この考案の一実 施例を示す図である。まず構成を説明すると、１は低圧ポンプであり、その油吸 入側は油送管６−１を介して油タンク５に接続されている。低圧ポンプ１の油吐 出側は油送管６−２を介して高圧ポンプ２の油吸入側に接続されている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention. First, the configuration will be described. 1 is a low-pressure pump, the oil suction side of which is connected to the oil tank 5 via an oil feed pipe 6-1. The oil discharge side of the low pressure pump 1 is connected to the oil suction side of the high pressure pump 2 via an oil feed pipe 6-2.
【０００６】 高圧ポンプ２の油吐出側は油送管６−３を介して、内部に油往路８と油戻路９ を有したノズルホルダー３の油往路８側に接続されている。ノズルホルダー３の 先端には戻り形のノズル４が接続されている。ノズルホルダー３の油戻路９は油 戻管７を介して、低圧ポンプ１と高圧ポンプ２を接続する油送管６−２の途中に 接続されている。油戻管７の途中には第１の電磁弁１０と、圧力センサー１１が 接続されている。コントローラ１２は、圧力センサー１１ならびに図示していな い給湯機等の温度、流量等を入力とし、演算し、低圧ポンプ１と、高圧ポンプ２ と、油電磁弁１０へ出力している。第２の電磁弁１３は、低圧ポンプ１と、並列 に設けたバイパス管１４の途中に設置される。The oil discharge side of the high-pressure pump 2 is connected to the oil outgoing path 8 side of the nozzle holder 3 having the oil outgoing path 8 and the oil returning path 9 inside through an oil sending pipe 6-3. A return type nozzle 4 is connected to the tip of the nozzle holder 3. The oil return passage 9 of the nozzle holder 3 is connected via an oil return pipe 7 in the middle of an oil feed pipe 6-2 connecting the low pressure pump 1 and the high pressure pump 2. A first solenoid valve 10 and a pressure sensor 11 are connected in the middle of the oil return pipe 7. The controller 12 receives the temperature, the flow rate, and the like of the pressure sensor 11 and a water heater (not shown) as inputs, calculates them, and outputs them to the low pressure pump 1, the high pressure pump 2, and the oil electromagnetic valve 10. The second solenoid valve 13 is installed in the middle of a bypass pipe 14 provided in parallel with the low pressure pump 1.
【０００７】[0007]
次に作用を説明する。低圧ポンプ１で油タンク５より吸入された油は、ここで 加圧されて高圧ポンプ２に供給され、高圧ポンプ２で更に加圧し、戻り形ノズル ４に供給され、一部は噴霧され、残りの油は第１の油電磁弁１０を通って、低圧 ポンプ１と高圧ポンプ２を接続している油送管６−２の途中に戻される。 Next, the operation will be described. The oil sucked from the oil tank 5 by the low-pressure pump 1 is pressurized here and supplied to the high-pressure pump 2, further pressurized by the high-pressure pump 2, supplied to the return-type nozzle 4, and partially sprayed and the remaining Oil is returned to the middle of the oil feed pipe 6-2 connecting the low pressure pump 1 and the high pressure pump 2 through the first oil solenoid valve 10.
【０００８】 ここで、バーナーの停止信号によりバーナーが停止すると、低圧ポンプ１、高 圧ポンプ２が停止し、第１の油電磁弁１０が閉となるが、これらとほぼ同時に、 低圧ポンプ１のバイパス管１４に設けた第２の油電磁弁１３を開とする。つまり 、第１の油電磁弁１０は、低圧ポンプ１、高圧ポンプ２が動くとほぼ同時に開と なり、止まるとほぼ同時に閉となる。又、第２の油電磁弁１３は、低圧ポンプ１ 、高圧ポンプ２が動くとほぼ同時に閉となり、止まるとほぼ同時に開となるよう に制御される。Here, when the burner is stopped by the burner stop signal, the low pressure pump 1 and the high pressure pump 2 are stopped, and the first oil electromagnetic valve 10 is closed. The second oil electromagnetic valve 13 provided in the bypass pipe 14 is opened. That is, the first oil solenoid valve 10 opens at the same time when the low pressure pump 1 and the high pressure pump 2 move, and closes at the same time when it stops. The second oil solenoid valve 13 is controlled so that it closes almost simultaneously when the low-pressure pump 1 and high-pressure pump 2 move, and opens almost simultaneously when it stops.
【０００９】[0009]
以上のように、この考案によれば、その構成を、油タンクよりの油を吸入し所 定の油量を吐出する低圧ポンプと、低圧ポンプより送られた油を吸入し、高圧に 加圧する高圧ポンプと、戻り形ノズルと各々を接続する油送管と、戻り形ノズル より高圧ポンプと低圧ポンプの間の油送管に連結される油戻管と、油戻管の途中 に設けた第１の油電磁弁と、低圧ポンプの油吸入側と油吐出側とをバイパスする バイパス管と、バイパス管の途中に設けた第２の油電磁弁とで構成し、バーナー 停止時において、低圧ポンプの油吐出側から高圧ポンプの油吸入側に連なる油送 管、及びこれに接続される油戻管内の油の圧力が上昇するのを防止することによ り、次のバーナー点火時において、前記残圧の影響による異常燃焼を防止できる という効果が得られる。 As described above, according to the present invention, the configuration is such that the low-pressure pump that sucks the oil from the oil tank and discharges the predetermined amount of oil, and the oil that is sent from the low-pressure pump is sucked and pressurized to a high pressure. A high-pressure pump, an oil feed pipe connecting each of the return nozzles, an oil return pipe connected to the oil feed pipe between the high-pressure pump and the low-pressure pump from the return nozzle, and an oil return pipe provided in the middle of the oil return pipe. No. 1 oil solenoid valve, a bypass pipe that bypasses the oil suction side and oil discharge side of the low-pressure pump, and a second oil solenoid valve provided in the middle of the bypass pipe. When the burner is stopped, the low-pressure pump By preventing the oil pressure in the oil delivery pipe connected from the oil discharge side to the oil suction side of the high-pressure pump and in the oil return pipe connected to it to rise, the This has the effect of preventing abnormal combustion due to the effect of residual pressure. It is.
【００１０】[0010]
先に述べた第２の油電磁弁１３の代わりに、バイパス管１４の途中に絞り機構 １５を設けても、同等の効果が得られる。この場合、絞り機構１５はオリフィス でも、ベンチェリーでも、細管でも、あるいはニードルバルブで絞り度合いを調 節できるようにしても良い。又、バイパス管１４は必ずしも低圧ポンプ１の外部 に設ける必要はなく、低圧ポンプ１の内部に加工しても良い。 Even if the throttling mechanism 15 is provided in the middle of the bypass pipe 14 instead of the second oil electromagnetic valve 13 described above, the same effect can be obtained. In this case, the throttling mechanism 15 may be an orifice, a Bencherry, a thin tube, or a needle valve so that the degree of throttling can be adjusted. Further, the bypass pipe 14 does not necessarily have to be provided outside the low pressure pump 1, and may be processed inside the low pressure pump 1.
【００１１】[0011]
バーナーの停止信号によりバーナーが停止すると、低圧ポンプ１、高圧ポンプ ２が停止し、低圧ポンプ１と高圧ポンプ２と第１の油電磁弁１０の間に密閉され た油は、バイパス管１４、絞り機構１５を通じて低圧ポンプ１の吸入側に戻され るので、この部分の圧力が上昇することはない。 When the burner is stopped by the burner stop signal, the low-pressure pump 1 and the high-pressure pump 2 are stopped, and the oil sealed between the low-pressure pump 1, the high-pressure pump 2 and the first oil electromagnetic valve 10 is bypassed by the bypass pipe 14 and the throttle. Since it is returned to the suction side of the low-pressure pump 1 through the mechanism 15, the pressure in this part does not rise.
