従来、灯油のような液体燃料をバーナで燃焼さ

までの間は燃焼が行われないので暖房開始までか

熱のための電力消費量も無視できない。 Conventionally, when burning liquid fuel such as kerosene in a burner, combustion devices equipped with a vaporizer that heats and evaporates the fuel have been widely used to vaporize the fuel into fine particles or mist for good combustion. It is being The vaporizer is heated by electric resistance heat throughout the operation, or heated by electric resistance heat at the beginning of operation and then heated by combustion heat from a burner. Therefore, combustion does not occur from the time the operation switch is turned on and current begins to flow through the electrical resistance wire until the vaporizer is heated to a predetermined temperature, so it is necessary to wait a considerable amount of time before heating starts. Furthermore, power consumption for heating cannot be ignored.

消えの心配がある。 Therefore, various fuel-combined combustion devices have been proposed that use gaseous fuel at the beginning of operation to immediately start heating and heat the vaporizer, and then switch to liquid fuel at an appropriate time. One of them is Japanese Patent Application Publication No. 1973-
As disclosed in Publication No. 29132, when the vaporizer starts to vaporize liquid fuel, there is a vaporizer that guides it to the auxiliary nozzle of the burner and burns it, detects it with a flame detector and switches it. Not only does this require a nozzle, but also a passageway to guide the liquid fuel to the regular nozzle, which complicates the configuration of the burner and liquid fuel passageway. If switching is performed depending on the fuel, there is a concern that the firepower will be insufficient or the fire will go out due to a lack of fuel.

Also, at almost the same time, the magnetic core 23 decreases its magnetism, and the valve stem 20 having the permanent magnet 24 is pushed to the right in the figure by the force of the spring 21, separating the valve body 19 from the valve seat 18, thereby increasing the liquid fuel side. The on-off valve 5 is opened. At the same time, the valve stem 20 rotates the first lever 30 clockwise about the support shaft 36, and the second lever 31
is also rotated clockwise around the support shaft 34. Therefore, the claw 31b of the second lever 31 is attached to the pin 2.
8a, the valve rod 28 on the gaseous fuel side is pushed to the left by the force of the spring 29, and closes the on-off valve 9 on the gaseous fuel side. The cam 32 is pushed by the valve stem 28, rotates slightly clockwise, and is placed in the combustion position, and only liquid fuel is sent to the burner 11 for combustion (see Fig. 4).

is pushed to the left to close the on-off valve 5 and return to the state shown in FIG. 2. Thereafter, as the temperature decreases, the magnetic core 23 recovers its magnetism, and when operating again after returning to approximately room temperature, the fuel is switched in the same order as described above. When restarting operation before the magnetic core 23 recovers its magnetism, when the operation dial S is turned to the ignition position, both the on-off valves 5 and 9 are opened, but as soon as the hand is released, the combustion position is set and the gaseous fuel side is opened.

きわめて安全且つ便利なものである。 As described above, according to this proposal, gaseous fuel and liquid fuel are used together, and the gaseous fuel is supplied to the burner and combusted at the start of operation, so heating starts as soon as the operation switch is turned on, which is different from the conventional method. Not only is there no need to wait for a long time unlike combustion devices that use a vaporizer, but there is also no need to consume electricity to heat the vaporizer, making it economical to heat the vaporizer at the same time as heating the room using gaseous fuel. It can be done. In addition, the on-off valves of each fuel passage are opened and closed by a switching mechanism consisting of magnetic force changes due to heat and a combination structure of two levers and a cam, and both valves are closed when a fire is extinguished, but only the on-off valve on the gaseous fuel side is opened when a fire is ignited. Furthermore, when the vaporizer is heated to a predetermined temperature, the magnetic force that closes the on-off valve on the liquid fuel side decreases, which opens the on-off valve and closes the on-off valve on the gaseous fuel side. By selecting the magnetic core so that when the predetermined temperature is reached, the on-off valve on the liquid fuel side is kept closed until the vaporizer is heated to a temperature that can sufficiently vaporize the liquid fuel.
After switching, combustion can continue without fear of a decrease in thermal power or burning out due to lack of fuel, and in combination with the fact that fuel switching is performed automatically, it is extremely safe and convenient to use.
