Description

Gas apparatus

The present invention relates to a gas mechanism such as a gas furnace that can control the operation of the gas burner, such as supplying fuel gas to the gas burner or adjusting the gas flow rate by, for example, an automatic return type light touch switch.

As a conventional gas stove, for example, Japanese Patent Laid-Open No. 7-94890 is known. The gas furnace is equipped with two Bunsen type furnace burners installed in the furnace gas and facing the ceramic plate type burners installed in the grill so as to face the opening of the ceiling plate. Branch pipes branched from one gas pipe provided with an on-off valve as solenoid valves are connected to the mixing pipe of each burner.

Each branch pipe is provided with a flow control valve for regulating the gas flow rate to each burner of the furnace and grill. The flow regulating valve includes, for example, a driving body for increasing or decreasing the passage area of the gas passage, and the driving body is driven by a motor such as a stepping motor.

Here, in a gas furnace provided with a plurality of gas burners each connecting branch pipes branched from one gas pipe, the supply of fuel gas must be controlled for each burner so that each burner can be used individually.

For this reason, the gas furnace is provided with a closing function in the flow regulating valve. Operation control such as ignition of each burner of the furnace and grill and adjustment of the thermal power are performed by an automatic return type light touch switch provided on the operation panel on the front of the furnace body.

When the light touch switch is pressed and operated to ignite the burner, the drive body is driven by the motor to shift the flow control valve from the valve closing position to the valve opening position, and the valve of the solenoid valve is opened to perform ignition. In this case, the flow rate control valve is controlled so that the fuel gas of the gas flow rate which strengthens the gas burner flows in order to ensure the ignition of the gas burner. The gas flow rate of the fuel gas is operated by pressing a light touch switch for controlling thermal power, driving the driving body by a motor to change the opening area of the gas passage.

However, since the solenoid valve cannot be closed when extinguishing any one of the gourd burners, for example, when two gourd burners are being used at the same time, the flow control valve corresponding to the gourd burner to be extinguished Need to close. In this case, since it takes several seconds to move the drive body to the position where the flow regulating valve is closed by the motor, there is a problem that it takes time to extinguish.

In addition, when igniting the burned-down goro burner, there is also a problem that it takes time to ignite to drive the driving body by the motor to the ignition position where the fuel gas of the gas flow rate for strengthening the gas burner flows. .

Moreover, in the early ignition of each burner, a large amount of current is required to simultaneously perform the operation of opening the solenoid valve and the operation of opening the flow control valve. In this case, for example, it is necessary to increase the trans capacitance, which is expensive.

A gas mechanism for providing a flow rate adjusting means for adjusting the gas flow rate and for controlling the operation of each gas burner with a light touch switch, characterized in that each branch pipe is provided with a second open / close valve.

According to the present invention, when the light touch switch is operated by giving an operation to ignite the gas burner, the first and second open / close valves are opened respectively. In this case, the second on-off valve is provided in the branch pipe, and the second on-off valve can cut off the supply of fuel gas to each burner. There is no need to transition to. Therefore, when the first and second open / close valves are opened, fuel gas immediately flows to the gas burner, and ignition operation is performed.

For example, when two gas burners are used, when the gas burner is extinguished, the gas burner can be extinguished by closing the second on-off valve. In this case, it is possible to extinguish the fire quickly by moving the drive body by the motor to shift the flow rate adjusting means to the valve closing position to extinguish it.

In addition, once the fired gas burner is ignited, the flow rate adjusting means is located at a position where the flow of the fuel gas is not interrupted. Therefore, when the second opening / closing valve is opened, the fuel gas is immediately supplied to the gas burner to ignite. For this reason, it can ignite quickly compared with ignition by moving from a valve closing position to an ignition position.

It is preferable that the flow rate adjusting means select one that does not have a waste paper function. As a result, since the high sealing property is not required for the flow control valve itself, the manufacturing cost is reduced.
