[Prior art] In recent years, in the grill that is integrated with the gas stove, 10 has been proposed to save the effort of flipping the conditioning object such as the fish placed on the barbecue net during conditioning and improving the convenience of the grill. The two-sided grill structure for sexual purposes. Therefore, a fire burner is provided on the top plate portion of the grill box, and a left and right fire burner is provided below the barbecue grill and on both inner side walls of the grill box. ^ Although gas valves with an on-off valve for controlling the supply of 15 m of fuel gas and a flow regulating valve for regulating the methane flow of fuel gas can be installed on each mother burner, it is possible to independently adjust the firing and firing conditions. The firepower of the burner, but this will lead to excessive costs. In addition, a grill using u to prepare fish, etc., does not require it to have a fine shrinkage performance of 20, such as a gas burner provided in the oven portion for cooking stews. The lower and lower burners can be set to two types of firepower positions, so that the conditioner will not feel inconvenient. Developed from this point of view is the gas valve disclosed in the Japanese Patent Laid-Open Gazette, which is provided with a "flow regulating valve" and the flow regulating valve includes: an i-th communication hole The fixed disk has 6 ridges, the invention description α /, a rotating disk with a second communication hole and rotatable by a motor. The invention is: 11 gas valves to supply fuel gas to the upper and lower burners and adjust the gas flow. At this time, it is formed in the solid; the four i-th connecting holes of the t disk are composed of two holes for making the gas flow $ large and two holes for making the gas flow small, and a pair of sizes The holes are arranged so as to correspond to the respective gas outflow portions. Then, the rotating disk is rotated, and each of the second communication hole and each of the first communication holes is made the same at each gas outflow portion, so that each of the upper combustion and the lower combustion can be burned. Device, set the fire position of two types of strong and weak. Problems to be Solved by the Invention However, the aforementioned invention provides the closing function of the flow rate regulating valve. That is, another through hole is provided in the fixed plate, and only the space where the first communication hole and the second communication hole communicate through the through hole has fuel gas flowing to the gas outflow portion. Therefore, the positions of the firepower of the upper and lower burners can only be combined in three types, which has the problem of poor usability. That is, when using each burner, the second communication hole must always be consistent with the through hole. Therefore, for example, if the second communication path is set, and the gas flow rate of the upper burner is strong and the lower burner is weak, it cannot be adjusted. Set the gas flow to a low-fire burner and a strong-fire burner. In addition, since the invention requires that the flow regulating valve with a closing function has sealing performance, it is necessary to process the rotary disk and the fixed disk with high precision, and high-priced sealing materials with high sealing performance are also required, resulting in high overall cost. problem. Here, the present invention has been made in view of the foregoing problems, and it is an object of the present invention to provide a gas valve, which can set two fires at each burner and each burner 571052 玖, the invention explains the force position, and can be smoothly switched at the same time Such locations and can be made by low cost producers.

According to the present invention, when the on-off valve is opened, the fuel gas flows into the internal passage. Then, if the rotary disk is rotated, the size of any of the second communication hole and the first communication hole is consistent with each of the gas outflow portions, and the corresponding communication holes corresponding to the foregoing can be separately supplied. The flow of fuel 8 571052 玖, invention description gas to gas outflow. In addition, 'when it is desired to change the gas flow rate of the fuel gas supplied to one of the gas outflow parts, rotate the rotary disk in response to this to make the second communication hole and the first communication hole of any size consistent with the gas outflow part. Consistent, borrow 5 to switch gas flow. At this time, because the holes of a pair of large and small are respectively aligned with the gas outflow portions and arranged on the same circumference, the gas flow can be switched cyclically by rotating the rotary disk, and the circulation is from supplying to one gas The gas flow from the outflow section is large and the gas flow supplied to the other gas outflow section starts to increase. The gas flow through the gas supply section to one side is large and the gas flow supplied to the other gas outflow section is small. The gas flow of the outflow part is small and the gas flow supplied to the other gas outflow part is small, and finally the gas flow to the one gas outflow part is small and the gas flow supplied to the other gas outflow part is large. 15 Moreover, the right side can be used to make the rotating disk forward and reverse by the driving device. When the rotating position of the rotating disk is grasped and the rotation direction is selected, the gas flow rate supplied to one gas outflow portion can be quickly and smoothly switched. [Embodiment I] The embodiment of the invention. With reference to FIG. 1 and FIG. 2, reference numeral 1 is used for a grill including a Bunsen burner and a lower burner (not shown), for example. Maoyue's gas valve. The gas valve i includes a valve housing 12 with an internal passageway. At the end of the valve housing 12 (the right side of the figure!), There is a gas streamer which communicates with the internal 9 571052 (the invention description passage η). And a solenoid valve 2 as an on-off valve for controlling the supply of fuel gas is provided on the downstream side of the gas flow person section 13 at the other end of the valve housing 12 (the left side of FIG. 1), A gas outflow portion 14 having two gas passages 14a and ⑽ communicating with the internal passage 11 and being independent of each other is provided. In addition, each gas passage is a mixing pipe connected to each of the burners for firing and firing. The body 12 is provided with a regulating valve 3, which is located on the downstream side of the solenoid valve 2 and on the upstream side of the gas outflow portion 14, and is used to reduce the pressure fluctuation of the fuel gas which causes unstable combustion of each burner on and off the fire. The regulating valve 3 has a regulating body 3 connected to the outer peripheral surface of the valve housing 12, and inside the regulating valve body 31, a warp spring ^ is accommodated to the direction of the valve seat U provided in the internal passage 11. Potential ㈣ diaphragm 34. 15 Moreover, between the downstream side of adjustment 阙 3 and A flow regulating valve 4 is provided between the gas outflow. The flow regulating valve 4 has a circular fixed plate 42 'embedded in the valve housing 12 and a circular rotation on the lower side of the circular regulating plate 4 through a private sealing material 41. Disk 43. Here, if the closing function of the flow regulating valve 4 is given, problems such as a reduction in the combination of firepower positions will occur. 20 In this embodiment, the 漭 景 漭 # is not given the closing function of the valve 4 but only The fuel gas supply is controlled by the solenoid valve 2. Therefore, since the flow rate adjustment _ 4 itself is not required to have a high degree of tightness, it is not necessary to process with high precision, and the material of the tightly sealed material 41 and the degree of freedom of the grease are not required. Increasing the 'helps to reduce costs. 10 玖, description of the invention With reference to Figure 3 and Figure 4_, the fixed plate 42 is provided with four circular first communication holes 44a, 44b, 45b ° Connect! The holes 44a, 44b, 45a, and 45b are structured into two large holes 44a and 45a, which are set to have 14 households and L for the gas outflow part. When the machine enters, the fire power of each burner is changed. The opening area of fuel gas with strong gas flow, and two small holes 44b, ^ Hachiman has formed an opening area for fuel gas flowing into the gas outflow portion 14 to reduce the combustion power of each gas flow, and is arranged at a certain interval on the same circumference. In addition, as shown in FIG. 3 As shown in the figure, a partition is provided on the sealing material 41-'to make each other's size opposite-the holes 仏, 44b, 45a, 45b are respectively corresponding to the gas passages 14a, ⑽ of the gas outflow section 14. As shown in Figure 1 Shower's rotating disk 43 is freely rotated by the rotating shaft 51 of a motor 5 such as a recording motor and stepping motor provided on the valve housing 12. This 4 'is equipped with a rotation angle detection device 52 on the rotating shaft 51 and can be measured. The rotation position of the rotary disk 43 is output. Also, the second rotary hole 43 is provided in the rotary disk 43. As shown in FIG. 4, the second communication hole 46 is a long hole in the circumferential direction, and the size of the hole can be the same as that of the fixed plate 42 at the same time! The two adjacent holes in the communication holes 4 and 45a and 45b are consistent with each other, and when changing the firepower, it will not simultaneously block a pair of holes 44a of the same size as the gas passage H 14b that changes its firepower. , 44b or 45a, 45b. Thereby, the rotating disk 43 is rotated by the motor 5 so that the second communication hole 46 coincides with the two holes 44a, 44b, 45a, and 45b of the communication hole 1 in sequence, and the state of the burner can be switched step by step, and its circulation system Starting from the strong burner, the lower 571052 玖, the description of the invention, the burning state of the fire is strong, after passing through the strong burner, the weak burner is weak, and the weak burner, the weak burner is weak State, the last to the upper burn is weak, the lower burner is strong (refer to Figure 5). At this time, the motor 5 can be configured so that the rotating disk 43 can be rotated forward and backward freely. For example, let the control unit (not shown) for controlling the operation of the gas valve 1 memorize the rotation angle of the rotating shaft 51 corresponding to each fire power of each burner that fires and fires, and change the fire When the firepower of either the burner or the down-burner is used, the rotation direction of the rotary disk 43 is determined by the rotation angle of the rotation shaft 51 detected by the rotation angle detection device 52 and the stored rotation angle, and The rotary disk 43 is rotated in this direction, thereby quickly and smoothly switching the fire power of the upper burner or lower burner. In addition, the control switch of the gas valve in this embodiment may include, for example, a touch switch for adjusting the ignition / extinguishment of each burner that is on and off, and the selection of each burner that is on and off is strong. Or a weak firepower change touches the 15-control switch as an example. In addition, when the burners of the upper and lower fires are ignited, the second communication holes 46 of the rotary disk 43 and the large holes 44a and 45a can be matched with each other. Hereinafter, the operation of the gas valve 1 according to this embodiment will be described with reference to Figs. 4 and 5. If the touch switch at the start of conditioning is adjusted to ON, it is easy to ignite the burners of the upper and lower fires. Therefore, each of the second communication hole 46 and the first communication hole 46 of the rotary disk 43 is rotated to rotate the square 43. Large holes 44a, 45a are the same. At this time, the rotation angle measured by the rotation angle detection device & is 0 degree. Next, the solenoid valve 2 is opened. At this time, the inflowing fuel gas is opened to the inside and the wither valve 3 is opened, and the fuel gas 12 571052 玖 is supplied through the flow regulating valve 4, and the gas passages 14a and 至 to the gas outflow section 14 are explained. At this time, fuel gas is supplied to the mixing pipe of each burner at a gas flow rate that can increase the fire power of each burner that is on and off. Then, the ignition operation of each burner is performed. Here, for example, in order to change the fire power of the lower-burning burner and change the touch switch according to the fire power of the weak 5 fire power, first of all, the corresponding control unit memorized in the control unit for controlling the operation of the gas valve 1 corresponds to each combustion. The rotation angle of the heating power of the device and the rotation angle of the rotation shaft 51 measured by the rotation angle detection device 52 determine the rotation direction of the motor 5. ^ For example, if the rotation angle that the control unit memorizes corresponds to 10 for the upper burner and 10 for the lower burner is weak, the motor 5 rotates in the positive direction indicated by ① in Figure 5 The rotation shaft 51 is up to the second communication hole 46 of the rotating disk 43 and the small hole 45b of the first communication hole (the rotation angle measured by the rotation angle detection device 52 is 90 degrees, refer to FIG. 4 (b)). At this time, when the rotating disk 43 is rotated, the large hole 44a of the first communication hole used to make the 15 firepower of the lit burner keep straight with the second communication hole 46, so the Firepower will not change. · When changing the touch switch to change the fire power of the fired burner in the aforementioned state, when the fire power of the weak fired power is changed (at this time, the control unit memorizes the rotation angle corresponding to the weak fired burner and the fired burner weak) It is 18 °), as with the former of the above, it is determined that the rotation direction of the motor 5 is the ① direction, and the motor. 5 rotates the rotation shaft 51 to the small hole 44b of the second communication hole flap and the first communication hole. (The rotation angle measured by the rotation angle detection device 52 is 180 degrees, refer to FIG. 4 (c)). In order to change the fire power of the lower burner in the aforementioned state, press the fire power 13 571052 发明, the description of the strong fire power dual touch switch (At this time, so that the control unit remembers that the corresponding burner is weak, fire The strong rotation angle of the burner is 270 degrees), it is determined that the rotation direction of the motor 5 is the direction ①, and by rotating the rotation shaft 51 of the motor 5, the second communication hole 牝 and the large hole 45a of the first communication hole are the same ( The rotation angle measured by Nongzhi 52 was measured at 5 ° with a 5 ° turn angle, refer to Fig. 4 (d)). Contrary to the above, in order to make the upper burner weak and the lower burner weak? The text changes the firepower of the burning burner and changes the touch switch sundial according to the firepower of the S firepower. In this embodiment, the control unit memorizes the rotation corresponding to 10 strong firepower burners and weak firepower burners. The angle is 90 degrees, so it is absolutely necessary to rotate the rotation shaft 51 in the opposite direction shown by ② in FIG. 5. Then, the rotation shaft 51 is rotated by the motor 5 to the second communication hole 牝 of the rotary disk 43 and the large hole 45a of the first communication hole until the rotation angle is 90 degrees measured by the rotation angle detection device 52, refer to the fourth Figure (b)). 15 Effect of the Invention As explained above, the effect that the gas valve of the present invention can exert is that it can set 2 fire positions for each burner that fires and fires, and can switch these positions smoothly at the same time. , And can be a low-cost producer.
