前記気化器６を構成して成る。The present invention provides a throat portion 3a of the mixing tube 3 of the burner 1.
A heat receiving plate 11 is provided on the outer periphery of the burner 1 to receive combustion heat from the burner 1, and a fuel passage 1 connected to the nozzle 5 is provided on the heat receiving plate 11.
2 and an electric heater 13 for heating the heat receiving plate 11, the vaporizer 6 is constructed.

１からの燃焼熱を受けられるようにした。This will be further explained, and the heat receiving plate 11 has a female disk 11a cut from a copper plate or other material with good thermal conductivity and a male disk 11b that fits into the female disk 11a.
By forming a fuel passage 12 along the circumferential direction, and providing a through hole 11C in the center of which the throat portion 3a of the mixing tube 3 is attached, and attaching the throat portion 3a of the mixing tube 3 to the through hole 11C. The vaporizer 6 is supported by the mixing tube 3, with the upper part of one side of the heat receiving plate 11 facing the burner 1, and an electric heater 13 provided along the vicinity of the fuel passage 12 on the other side. was configured. Incidentally, burner body 2
The combustion section 4 provided in the burner body 2 is configured to extend not only to the upper surface of the burner body 2 but also to the upper half of the side surface that the heat receiving plate 11 faces. Made it possible to receive combustion heat.
しかして該燃料通路１２の下部に前記電磁ポンプ１０の
突出口１０ａを接続すると共に該燃料通路１２の上部に
前記ノズル５を接続させた。Thus, the outlet 10a of the electromagnetic pump 10 was connected to the lower part of the fuel passage 12, and the nozzle 5 was connected to the upper part of the fuel passage 12.
尚該受熱盤１１の前記ノズル５と対向する而の該混合管
３の入口部分近傍にはフィン１４を設けて前記−時空気
を該フィン１４によって多少とも加熱させるようにした
。A fin 14 is provided near the inlet of the mixing tube 3 facing the nozzle 5 of the heat receiving plate 11 so that the air is heated to some extent by the fin 14.
尚ノズル５はこれに臨ませた電磁弁５ａによってその噴
出口５ｄを開閉されるもので、該電磁弁５ａはこれをば
ね５ｂに抗して吸着開弁させるときのみ大きい吸着力を
要するが一旦吸着して終えばさほど大きな吸着力を要し
ない。The nozzle 5 is opened and closed by a solenoid valve 5a facing the nozzle 5, and the solenoid valve 5a requires a large suction force only when it is opened by suction against the spring 5b. Once the adsorption is completed, a large adsorption force is not required.
そのため該電磁弁５ａのソレノイド５Ｃへの通電回路を

イド５Ｃに流し、吸着保持時は該コンデンサＣを介して
小電流をソレノイド５Ｃに流すようにした。Therefore, as shown in Fig. 3, the current supply circuit to the solenoid 5C of the solenoid valve 5a is provided with a capacitor C having a small capacity, for example, about 4 μF, in parallel with the actuation switch S that closes instantaneously. A large current is caused to flow through the solenoid 5C, and a small current is caused to flow through the solenoid 5C via the capacitor C during adsorption and holding.

れるようにした。When the capacitor C is used in parallel with the actuating switch S in this way, it is advantageous because it does not generate heat, compared to the case where a resistor is used as is generally done. Furthermore, fuel passage 12
As shown in FIG. 3, a wire mesh 15 made of stainless steel or the like is provided to more effectively transfer heat from the heat receiving plate 11 to the fuel.
次ぎにその作動を説明する。Next, its operation will be explained.

る気化した燃料が再凝縮する事はない。In this device, by energizing the electric heater 13 before supplying fuel, the heat receiving plate 11 is heated, and the mixing tube 3, especially the inlet side, is heated. Therefore, if the electromagnetic pump 10 is then operated to supply fuel, the fuel will immediately vaporize within the fuel passage 12 provided in the heat receiving plate 11. Therefore, when the electromagnetic valve 5a is opened thereafter, the mixture is sent from the nozzle 5 to the mixing pipe 3 provided in the burner. At this time, since the mixing tube 3 has been heated in advance, the vaporized fuel injected from the nozzle 5 within the mixing tube 3 will not recondense.

ヒータを必要とせずその構造も簡単である。If the electric heater is energized before supplying fuel,
As the heat receiving plate is heated, especially the inlet side of the mixing tube is heated. Therefore, when fuel is supplied thereafter, the fuel is immediately vaporized in the fuel passage provided in the heat receiving plate, and is sent from the nozzle to the mixing pipe provided in the burner. At this time, since the mixing tube is heated in advance, the vaporized fuel injected from the nozzle inside the cold mixing tube does not recondense as in the conventional example. In this case, the problem of producing a unique odor can be solved, and since the heat of the vaporizer is used, there is no need for a separate heater to heat the mixing tube, and the structure is simple.
