Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustion device having a timer device, and provides a safe, reliable, and inexpensive method for taking necessary and sufficient preheating time for activating a catalyst at the start of combustion in a catalytic burner. The purpose is to obtain. Conventionally, electric and mechanical timers for controlling time have been considered, but there are none like the present invention. An embodiment of the present invention will be described in detail below.

The description of each part in FIG. 1 is as follows.

1 is a gas inlet, 2 is a gas tank with a safety valve, and is connected to the gas passage to the main nozzle 3, the gas passage 15 of the timer valve 5, and the gas passage 14 that is controlled to open when the knob 12 is operated and close when the operation is released. has been done. 3 is a main nozzle that determines the gas flow rate to the main burner, 4 is a catalyst burner, 5 is a timer valve operated by a knob 13, 6 is a heating nozzle to the heating burner, 7 is a heating burner, and 8 is a gas cooker 2. Pilot burner a, 9, which burns constantly when open, is operated by operating knob 12.
Pilot burner b, 10, which burns only while operating
11 is a thermocouple heated by pilot burner 8; 11 is a thermocouple heated by pilot burner 9; 12 is an operating knob; 13 is a knob for operating a timer; 14 is a gas passage to the pilot burner; 15 is a timer valve. It is a passageway leading to. An example of the operation will be described below.

Figure 1 shows the state before starting operation, gas is at gas inlet 1
It is in. In Figure 2, the gas passages 3, 14, and 15 are opened by operating the knobs 12 and 13, and the gas is supplied to the gas inlet 1, respectively.
The catalytic burner 4, the pilot burner 8, the pilot burner 9, and the heating burner 7 are then ignited by the ignition device linked to the burner 2, and the flame transfers to cause combustion. Then, the thermoelectromotive force generating elements 11 and 10 are heated, and the safety valve inside the pot 2 is heated.
Hold the knob until the safety valve in the timer valve 5 can be held open.

When the operation of the operating knobs 12 and 13 is stopped when the electromotive force generated by the thermoelectromotive force elements 10 and 11 reaches a state where the safety valve is opened sufficiently, only the gas passage 14 is closed. (The valve inside Kotoku 2 closes when you release the control knob.)
The pilot burner 9 is extinguished. Then, the gas continues to flow through the gas passage 15, which is a passage branched from the middle of the gas passage to the main nozzle 3, and the heating burner 7 and the pilot burner 8 are combusted to continue heating the catalytic burner 4.

Figure 3 shows that the electromotive force of the thermocouple 11 gradually decreases,
Eventually, the safety valve in the timer valve 5 becomes unable to hold and becomes closed, and the gas reaching the heating burner 7 is closed and the fire is extinguished. This completes the heating of the pine surface of the catalytic burner.

In FIG. 4, the catalytic burner 4 is activated and performs good combustion.

As described in detail in the operating sequence of FIGS. 1 to 4, the time required to heat the thermocouples 10 and 11 and hold each safety valve open, and the time required to stop heating the thermocouple 11 and the timer 5 The total time taken until the safety valve closes is the combustion time of the heating burner 7, that is, the heating time of the catalytic burner 4.

It is a well-known fact that the relationship between the attraction current and withdrawal current value of the safety valve is the relationship of attraction value>departure value. Further, the operating knobs 12 and 13 can be interlocked by a mechanical method.

As described above, according to the present invention, the preheating time for catalytic combustion at the time of starting combustion of the catalytic burner can be extremely easily and safely ensured.
