バーの部を示す。 Consider a water heater as an example of a conventional gas appliance.
Figures 1 and 2 show a conventional water heater and its control diagram. In FIG. 2, when outlet 1 is connected to a power source, transformer 2 provides the voltage necessary to control the appliance. In FIG. 1, when water is supplied to the heat exchanger 16 and the flow switch 3 is turned on, the main controller 15 opens the primary control valve 4, and at the same time, the ignition transformer 14 causes the spark plug 5 to be discharged. Gas comes out from the pilot burner 6 and is ignited by the spark plug 5. The thermocouple 7 senses this pilot flame, and in response, the main controller 15 opens the secondary control valve 8. The gas passes through the gas burner 9, the secondary control valve 8,
It is sent to the main burner 10. Here, the pilot flame ignites and ignites the main burner 10. The above is a simple explanation up to ignition, but when the appliance is installed and operated, air in the gas piping must first be vented in order for the gas to be sent to the primary control valve 4. When performing this air removal from the pilot burner, it takes 30 minutes to an hour, and work efficiency is extremely poor. Further, if air is suddenly and continuously removed from the main burner 10, it is dangerous because it may cause a backfire or explosion when the gas is released. In addition, in FIG. 1, 17 indicates a cover portion of the gas appliance.

クフアイヤー等の事故も生じない。 To explain the present invention using the drawings, in FIG. 3, when the outlet 1 is connected to a power source, the voltage necessary for control is obtained by the transformer. When the flow switch 3 is turned on, the controller 11 starts operating, the primary control valve 4 opens via the controller 11, and gas is guided to the pilot burner. At this time, the spark plug 5 is discharging by the ignition transformer 14, but since there is only air and no gas has come out yet, if the pilot burner does not ignite immediately (generally for about 5 seconds), the air bleed Turn on switch 12. This causes the controller 11 to control the timer circuit 13.
will become linked. This timer circuit 13 is also provided with a function of opening and closing the secondary control valve 8, and controls the secondary control valve so that it opens only for a short time at arbitrary time intervals, and repeats this opening and closing operation. By venting air from the main burner in this way, the time required for venting the air is significantly shortened, and it is also possible to prevent accidents such as explosive ignition and backfire that occur when air is vented from the main burner suddenly and continuously.
As an example, assume that the secondary control valve 8 is closed for 5 seconds and opened for only 1 second. Generally, the area ratio between the pilot burner and the main burner is 200, so if it takes 30 minutes to bleed air from the pilot burner, in this example, the air can be bleed in about 9 seconds. Furthermore, since raw gas is released from the main burner for only 1 second every 6 seconds, the amount of released gas is small compared to the amount of air, so accidents such as explosive ignition and backup fire do not occur.

できるという効果がある。 As explained above, by opening the secondary control valve for a short period of time at certain intervals, the present invention eliminates the possibility of explosive ignition or backup fire accidents, unlike when gas is continuously released from the main burner. Moreover, it has the effect of significantly shortening the degassing time during trial operation.
