DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention automatically and automatically boil and cook a staple food and a side food with the same fuel (automatic ignition → automatic extinguishing possible or automatic ignition → manual extinguishing possible), and a plurality of oil burners as a whole. Alternatively, automatic cooking with excellent functionality, operability, reliability, safety, workability, and economy, which can be individually controlled so that the cooking amount can be selectively performed as needed, such as a large amount or an arbitrary amount, etc. The present invention relates to a vaporization type combustion device.

2. Description of the Related Art Conventionally, as an apparatus of this type, for example, Japanese Utility Model Application Laid-Open No. 56-13653 or Japanese Utility Model Application Laid-Open No. 61-89.
No. 647 and the like.

In the former case in the above prior art, a preheater is provided in a gas flow passage from the vaporizer to the burner, the preheater is connected to a power supply side from a power switch, and the preheaters are normally parallel to each other. An open relay contact and a normally open delay thermostat are connected in series, a first relay contact is controlled by a first relay connected in series with a power switch, and the delay thermostat is closed when the burner exceeds a set temperature. With this configuration, it is possible not only to obtain stable combustion of blue fire at the same time as the start of combustion, but also to keep the gas flow passage heated for a while after the combustion is stopped because the preheater is controlled by the delay thermometer. If the gas is reburned a short time after that, even if the vaporized gas flows instantaneously, heat will not be deprived in the gas flow passage, and the same stable combustion of blue fire as at the start of combustion Are as hereinbefore way is, also in the latter case, the vaporizer for vaporizing a liquid fuel,
A nozzle for injecting the liquid fuel vaporized by the vaporizer to a burner, heating means for heating the vaporizer to a liquid fuel vaporization temperature, and operating the heating means by sensing the temperature of the vaporizer A control device for controlling stop, and a detecting means for detecting the consumption of the liquid fuel is provided,
The controller is configured to vaporize by a detecting means configured to increase the heating control temperature when the amount is large and to decrease the heating control temperature when the fuel consumption is small based on the output signal of the detecting means. Since the consumption of the liquid fuel flowing into the vessel can be detected and the carburetor temperature is controlled based on this, there is no difference between the vaporization surfaces of the vaporization elements in the carburetor during strong combustion and weak combustion. This is to enable stable combustion.

[0004]

[SUMMARY OF THE INVENTION However, the above case of the prior art, is of just as both simply stable combustion by the combustor is obtained by ignition electrodes
