る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to combustion appliances such as water heaters, and more specifically,
A diaphragm type flow regulating valve is interposed in the fuel gas supply path to the burner, and the fuel gas supply path includes:
The present invention relates to a combustion appliance in which an on-off valve is installed at an upstream side and a downstream side of the flow rate regulating valve.

Conventionally, this type of combustion appliance, taking a water heater as an example, automatically opens the upstream shut-off valve and the downstream shut-off valve at the same time based on an ignition command such as turning on a water flow sensor installed in the water supply channel. Alternatively, after opening the on-off valve on the upstream side, the on-off valve on the downstream side is opened (for example, see Japanese Patent Laid-Open No. 165522/1983).

し易い問題があつた。
However, in the above conventional combustion appliance, both the upstream and downstream on-off valves open at the same time, or
Since the downstream on-off valve opens after the upstream on-off valve opens, the source gas pressure upstream, which is higher than the upstream on-off valve, is applied to the diaphragm of the diaphragm type flow regulating valve located between the two on-off valves. (Even if both on-off valves are opened at the same time, the possibility of such an impact being applied is low due to the throttling action of the on-off valve on the downstream side.) However, due to this impulsive gas pressure application, there was a problem in that the diaphragm was prone to malfunction at an early stage.
本発明の目的は、両開閉弁に対する合理的な開
放制御により上記問題の解消を図る点にある。 An object of the present invention is to solve the above-mentioned problem by rational opening control of both on-off valves.

A characteristic configuration of the combustion appliance according to the present invention is that a controller is provided that opens the downstream on-off valve and then opens the upstream on-off valve among the on-off valves based on an ignition command. Effect/
The effects are as follows.

In other words, based on the ignition command, the downstream on-off valve opens first, and then the upstream on-off valve opens, so the high source gas pressure that is led downstream by the opening of the upstream on-off valve is already It can be smoothly released to the burner side further downstream (that is, the open system side) through the open downstream opening/closing valve.

As a result, according to the present invention, it is possible to suppress and avoid the impulsive application of high source gas pressure to the diaphragm of the diaphragm type flow rate regulating valve located between both on-off valves, thereby preventing functional failure of the diaphragm. It has now been possible to effectively prevent this.

After operating at N n for the first set time t 1 (approximately 0.3 seconds), operate at the rated rotation speed N R.

After opening the first solenoid valve 5A, when the third set time t 3 (about 0.1 seconds) has elapsed, the second solenoid valve 5A is opened.
B and the safety valve 7 are opened, and the proportional valve 6 is opened.
is operated so that the gas supply amount Q becomes the set flow rate q.

に、燃焼LED２０を作動（点灯）させる。 As a result, when ignition occurs and the flame rod current I of the flame rod 10 is generated, the flame rod current I is generated for a fourth set time from the start of generation of the flame rod current I.
After waiting for t4 , the igniter 11 is stopped and the combustion LED 20 is activated (lit).
以上が点火制御で、第１、第２のバーナ１Ａ，
１Ｂへのガス供給量Ｑが比例弁６で最大（max）

緩点火となつて、点火性が向上される。 The above is the ignition control, and the first and second burners 1A,
Gas supply amount Q to 1B is maximum (max) with proportional valve 6
Since the flow rate is limited to the set flow rate q instead of q, the ignition is slow and the ignition performance is improved.

フアン３も最大回転数Nnで作動する。 Then, based on the temperature detected by the temperature sensor 17 and the set temperature of the temperature setting device 18, the proportional valve 6 is operated so that the gas supply amount Q becomes a flow rate that makes the detected temperature become the set temperature. The rotation speed of the fan 3 is controlled according to the gas supply amount Q, and when the difference between the detected temperature and the set temperature is below the set temperature, and when the set temperature is below the set value, the first solenoid valve 5A reversibly occlude the
In addition, if the detected temperature does not rise to the set temperature even if the heating capacity is at its maximum, the water flow control valve 16 is throttled. This is combustion control for temperature adjustment accompanied by capacity switching. Note that at the beginning of combustion control, the difference between the set temperature and the detected temperature is greater than the set temperature, so the gas supply amount Q is at the maximum (max).
Fan 3 also operates at maximum rotation speed N n .

塞される。これが正常時の消火制御である。 Then, as the faucet 14 is closed, the water amount sensor 13
When the information from the water becomes less than the set water amount, the second solenoid valve 5B, the safety valve 7, and the proportional valve 6 are closed, the combustion LED 20 is turned off, and from this point on, the fifth set time t 5 (7 The fan 3 starts operating at the rated rotational speed N R over a period of about 1 minute). On the other hand, if the first solenoid valve 5A is already closed at the above-mentioned time point, the first solenoid valve 5A is opened for the sixth set time t 6 (about 1 second) and then closed, If the first solenoid valve 5A is open, the second solenoid valve 5B
After the [safety valve 7] is closed, the first electromagnetic valve 5A is closed when the sixth set time t6 has elapsed. This is normal fire extinguishing control.

It is determined that there is no ignition, and the second electromagnetic valve 5B, the safety valve 7, and the proportional valve 6 are immediately closed, the combustion LED 20 is blinked, and the fan 3 is turned off for an eighth set time t8 (approximately 10 seconds). ), while the sixth safety valve is operated from when the safety valve 7 is closed.
When the set time t6 has elapsed, the first solenoid valve 5A is closed and the igniter 11 is stopped. This is control in case of misfire.

The first and second electromagnetic valves 5A and 5B, the safety valve 7, and the proportional valve 6 are closed, the combustion LED 20 is flashed, and the fan 3 is turned on and off at the maximum rotation speed N n .
It is operated for a set time t8 .

However, when the fire is ignited, it opens before the safety valve 7, and when the fire is extinguished, it closes after the safety valve 7. the result,
When the safety valve 7 opens for ignition, the first solenoid valve 5A has already opened and the fuel gas flows into the first burner 1A.
Therefore, when the safety valve 7 is opened, the fuel gas flows smoothly and the gas pressure does not act as an impact on the diaphragm of the proportional valve 6. Moreover, even after the safety valve 7 is closed to extinguish the fire, the first solenoid valve 5A opens or remains open, and the portion of the fuel gas supply path 4 downstream of the proportional valve 6 is Since the first burner 1A is opened to the outside and gas pressure escapes, excessive gas pressure is not applied to the diaphragm of the proportional valve 6.
