The flow regulating valve has, for example, a driver that increases or decreases a passage area of a gas passage, and the drive system is driven by a motor such as a stepping motor. 9 Here, in a gas furnace provided with a plurality of gas burners each connected with a divergence of 20 gas tubes, the gas burners are connected. In order to be able to use each burner individually, it is necessary to control the fuel gas supply for each burner. . Therefore, the aforementioned gas furnace t is provided with a shutoff function of the flow regulating chamber. In addition, the automatic recovery type touch switch 'on the operation panel located on the front of the furnace body is used to control the ignition and fire power adjustment of each burner of the furnace and grill 5 1222509 发明, description of the invention when the touch switch is pressed In order 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 ignite the gas burner, the flow control valve 俾 is controlled to flow into the fuel gas at a gas flow rate that makes the gas burner strong. In addition, the gas flow rate of the fuel gas is adjusted by pressing the tactile switch for thermal power adjustment to drive the driving body by the motor, and the opening area of the gas passage is changed. t SUMMARY OF THE INVENTION 3 10 Problems to be Solved by the Invention However, in the above-mentioned 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. Use a flow control valve corresponding to the burner of the torch. 15 20 %% ′ Because it takes a few seconds for the flow regulating valve to become the closed position by driving the driving body with a motor, it takes a long time to stop the flame. In addition, if the burner of the fired furnace is to be re-ignited, the motor is used to drive the driving body to the ignition position of the fuel gas, which causes the gas burner to flow into the gas flow of the gas burner, so there is a problem of time-consuming ignition. In addition, during the initial ignition of each burner, a large current is required because the electromagnetic valve opening operation and the flow regulating valve opening operation are performed simultaneously. In this case, for example, the transformer capacity must be increased, resulting in high costs. In view of the foregoing problems, the present invention has as its object to provide a gas appliance that can quickly turn off and can reduce current consumption. Method for solving the problem 6 1222509 玖, 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 gas burner is connected to a gas pipe with an i-th opening and closing valve. And a 5 flow regulating device for adjusting the gas flow of the fuel gas supplied to the gas burners is provided on the branch pipes, and the actuators of the gas burners are controlled by a touch switch. It is characterized in that each branch pipe is provided with a second on-off valve. According to the present invention, when the touch switch is pressed to instruct ignition of the burner, the first and second on-off valves are opened separately. At this time, because the second on-off valve is provided in the branch pipe, and the second on-off valve can be used to block the supply of fuel gas to 10 burners. Therefore, it is not necessary to use a flow control valve when extinguishing the gas burner. It becomes the closed position. Therefore, if the i-th and second on-off valves are opened, fuel gas will flow directly to each gas burner for ignition operation. For example, if two gas burners are used at the same time and any one of them is to be extinguished, the 15 gas burner can be extinguished simply by closing the second on-off valve. At this time, compared with a person who drives the driving body with a motor to make the flow rate adjustment valve close to the valve closing position to fire, it can quickly turn off and fire. Also, 'If you want to ignite a burned gas burner, the flow regulating device is not in a position that will block the flow of fuel gas, so when the second on-off valve is opened, the fuel gas can be directly supplied to the gas burner for ignition. Do 20 work. Therefore, compared with the case where the flow rate adjusting device is changed from the valve-closed position to the ignition position to ignite, the ignition does not take time. In addition, the aforementioned valve-regulating flow regulating device may be one having no closing function. By this means, since the high degree of tightness of the flow regulating valve itself is not required, it contributes to reducing the manufacturing cost. 7 1222509 发明 Description of the invention t Embodiment] Embodiments of the invention Referring to Fig. 1 and Fig. 2, reference numeral 1 indicates a gas furnace according to the present invention. The gas furnace 1 includes a furnace body 11, and two furnace burners 13a, m having different heating amounts are provided in the furnace body 11, and the furnace body 11 has a circular opening facing the top plate 12 mounted on the furnace body surface.

The Yanhai grill 2 has a grill 10 meal 21, and a grill burner 2a (refer to FIG. 2) for conditioning a to-be-treated object is provided on the top of the grilled meal 21. The grill burner 2a is a burner constituted by installing a plurality of ceramic plates having a plurality of gas vents passing therethrough. A grill door 22 fitted with heat-resistant glass is installed in front of the opening of the grill box 21 so as to be freely removable. In addition, inside the grill door η, 15 is provided with a frame material 22a, which is freely removable, and the frame material ❿ can support the grill wood 23 and tunnel the switch of the grill door 22 to remove the grill plate from the grill. The rack box 21 is moved out and moved. In addition, the grill-shaped grill plate 23 formed in a disc shape is used to support a barbecue grill 24 on which to-be-conditioned objects such as fish are placed. The operation of the furnace combustion H 13a, 13b and the grill burner 2a is based on the tactile switches 点火, Mb, 15c and the tactile switch i6a for the ignition control of the operation panel 14 arranged at both ends. , I6b, i6c control. «The touch-type switch 15 and i6 on the printed circuit board are automatic recovery switches. When the conditioner touches it with a finger, it will output its control instructions to the gas furnace 1 sighed with the shovel. Operating microcomputer. In addition, the firepower 8 1222509, description of the invention Zhou Lang used the tactile switch 16 series to arrange two switches in parallel, which can increase or decrease the firepower of the furnace burners 13a, 13b and the grill burner 仏 in stages. As shown in Fig. 2, each mixing tube that burns to 2a in the two furnace burners 13a, 13b and the grill is connected to 5 manifolds 4U, 41b, 41c, which are divided by 4 gas pipes, respectively, and The gas tube 4 is provided with a first solenoid valve 3 which is an i-th on-off valve in the furnace body n. Each of the branch pipes 41a, 41b, and 41c is provided with motor-driven flow regulating valves 5a, 5b, and 5c for regulating the gas flow into the burners 13a, 13b, and 2a of the furnace and the grill. Considering Figures 3 and 4, the flow regulating valve 5a includes a valve housing 52 having 10 internal passages 51, and the valve housing 52 is provided with a gas inflow portion 53a and a gas outflow that communicate with the internal passage 51.部 53b. 53b. A stepping motor 54 having an encoder and other rotating detection devices is connected to the lower side of the valve housing 52, and one end of the rotating shaft 5 of the stepping motor 54 protrudes from the internal passage 51 through a sealing material 54b. . 15 Furthermore, in the inner passage 51, a rotary disk 55 is provided as a driving body connected to one end of the rotary shaft 54a, and a fixed disk 56 is positioned above the rotary disk 55 and is embedded in the valve housing 52. • As shown in FIG. 4, on the fixed plate 56, the opening areas of the holes 56a, 56b, 56c, and 56d of the fourth through hole li4 are different from each other and are arranged on the same circle on the other side on the rotating plate 55. The second communication hole 55a is provided with a sugar circle, and if the second communication hole 仏 is rotated by a predetermined angle, it is consistent with the holes 56a, 56b, and 5 of the first communication hole. The communication between the internal passage 51 and the gas outflow section is allowed. Then, the stepping motor 54 is driven to rotate the rotary disc 55 so that the second connection 9 1222509, the description of the invention, the through hole 55a matches the first communication holes 56a, 56b, 56c, and 56d, and the flow rate of the fuel gas is adjusted. Here, if the flow regulating valves 5a, 5b, and 5c are provided with a closing function to block the fuel gas supply in the branch pipes 4la, 41b, and 41e, for example, when 5: each furnace burner 13a, 13b 'is to be extinguished One of the gas burners is known to cause problems such as time-consuming ignition and flameout. In the present embodiment, instead of providing the closing function with high cost due to the flow regulating valve 5 &, the first solenoid valve 6a, 6b, 6e as the " closed " 10 is provided in the branch pipe 41. Thereby, the burners 13a, 13b, and 2a of the furnace and the grill can be quickly ignited and extinguished. In addition, when the ignition operation is to be performed, the ignition operation can be performed as soon as the jth and second electromagnetic coils 3 6a 6b, 6c 'are turned on. Therefore, the conventional stepping motor 54 is driven to change the flow regulating device from the valve closing position to the ignition position. And compared with those who ignite, the current consumption can be smaller. 15 Next, the operation of the gas furnace 1 of the present invention will be described. For example, in order to ignite the middle-furnace burner 13a, a tactile switch is pressed ... to instruct ignition, the first and second on-off valves 3 and 6a will be opened respectively. 20 Here, because the second on-off valve 6a 'is provided in the branch pipe 4U, the fuel gas supplied to each burner can be blocked by the second on-off valve 63. Therefore, the former furnace burner 13 & << The device 5 a moves to the ignition position where the gas flow that flows into the fire power is increased, and stops. In "Hai-like grievances", in order to ignite another burner burner, for example, when the light-touch switch 15b is pressed to indicate ignition, the second opening and closing position will be opened, and the fuel gas will be immediately supplied to the mixture from the burner burner.
