The gas stove includes two Bunsen burner burners provided in the furnace body facing the top plate opening, and ceramic burner burners provided on the grill. In addition, to the mixing pipe of each burner, a branch pipe branched by a gas pipe provided with an i-valve as a solenoid valve is connected. For each burner, a flow regulating valve is provided for regulating the gas flow rate of each of the detectors supplied to the oven and the grill. The flow regulating valve has an example; a driver for increasing or decreasing a passage area of a gas passage, and the drive system is driven by a motor such as a stepping motor. μ ”Here, there are many gas furnaces equipped with gas burners connected to divergent officers divided by one gas tube. ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ~ j Fuel gas supply can be controlled for each burner. Therefore, in the aforementioned gas furnace, a shutoff function is provided to the flow regulating chamber. In addition, through the operation of the front of the furnace body, the automatic recovery type touch switch on the panel to control the combustion of the furnace and the grill, and the "fire and fire power adjustment" 20 200302332 发明, description of the invention When the switch is used to indicate the ignition of the burner, the driving body is driven by the motor, so that the flow regulating valve is changed from the closed position to the open position, and at the same time, the solenoid valve is opened for ignition. At this time, in order to make the gas burner really ignited, the flow control valve is controlled so as to flow into the fuel gas of the gas flow that makes the gas burner strong. In addition, the adjustment of the gas flow rate of the fuel gas is to press the tactile switch for thermal power adjustment to drive the driving body by the motor, and change the opening area of the gas passage. I: Summary of the Invention 3 10 Problems to be Solved by the Invention However, in the aforementioned gas furnace, for example, if two furnace burners are used at the same time, and any one of the furnace burners is to be extinguished, the solenoid valve cannot be closed, so it must be closed. A flow control valve corresponding to the burner of the furnace to be extinguished. This k ′ takes a few seconds to set the flow rate adjustment 阙 to the closed position by driving the driving body with a motor, so that it takes a long time to stop the flame. In addition, if the burner of the extinguished furnace is to be ignited again, since the driving body is driven by the motor to the ignition position of the fuel gas flowing into the gas flow which causes the gas burner to become strong, the ignition is time-consuming. In addition, the initial ignition of each burner is performed by the solenoid valve at the same time. 1 operation and the operation of the flow regulating valve, so a considerable current is required. 9 For example, the pressure must be increased. 3 The soil is Guxia, which results in high costs. In view of the foregoing problems, the present invention has as its object to provide a gas appliance which can be quickly used and can reduce the current consumption. Method for solving the problem 20 200302332 Description of the invention In order to solve the problem, the present invention is a gas appliance, including a large number of gas burners, and each of the gas burners is connected to a gas valve with an opening and closing valve. At the same time, each branch pipe is provided with 5 to 5 /; of gas flow rate of fuel gas from fuel gas burners, σ, σ, δ to δ Helgo gas burner. A type switch controls the actuators of the gas burners, and is characterized in that second branch openings are respectively provided on the branch pipes. According to the present invention, when the tactile switch is pressed to indicate the ignition of the burner, the first and second valves are opened separately. At this time, since the second opening and closing valve is provided in the branch pipe, and the second opening and closing valve can block the fuel gas supply to 10 to each burner, it is not necessary to make the flow regulating valve into the closed position when the gas burner is extinguished . Therefore, if the first and second on-off valves are opened, the gas will flow directly to each gas burner for ignition operation. In addition, for example, if two gas burners are used at the same time and one of the gas burners is to be extinguished, the second gas burner need only be turned off to extinguish the 15 gas burner. At this time, compared with a person who drives a driving body with a motor to turn the flow rate regulating valve to a closed position to extinguish, it can extinguish quickly. In addition, if you want to ignite a flamed gas burner, the flow regulating device is not in a position that will block the flow of fuel gas. Therefore, when the second on-off valve is opened, the fuel gas can be directly supplied to the gas burner for ignition operation. 20 works. Therefore, the ignition of the flow rate adjusting device is less time-consuming than the case where the flow rate adjusting device is changed from the valve closing position to the ignition position for ignition. In addition, the aforementioned valve-regulating flow regulating device may be one having no closing function. Accordingly, since the high degree of tightness of the flow regulating valve itself is not required, it contributes to reducing manufacturing costs. 200302332 发明, description of the invention C Embodiment] | Embodiments of the invention Referring to FIG. 1 and FIG. 2, reference numeral 1 indicates the gas roasting of the present invention.
