The gas valve is provided with an on-off valve for controlling the supply of fuel gas and a flow regulating valve for regulating the gas flow of fuel gas. The fire power of each burner can be independently adjusted. This would result in excessive costs. In addition, the grill for conditioning fish and the like is not originally required to have, for example, a fine shrinkage of a gas burner provided in the oven section for conditioning stew I * birth b /. Each of the upper and lower burners can be set with two types of firepower positions, so that the conditioner will not feel inconvenient. Developed from this point of view is the Japanese Patent Publication Gazette No. 200 The gas valve disclosed in the specification No. 1_129312 is provided with a flow regulating valve, and the flow regulating valve includes: a fixed plate with a communication hole 2003 20 200302331 发明, description of the invention ^ having a second communication Rotary disk with holes and can be rotated by the motor. This invention can supply gas to the upper burner and τ fire burner and adjust the gas flow by 1 watt. 5 At this time, the 4th j-th communication formed on the fixed plate The holes are composed of two holes for increasing the gas flow rate and two holes for reducing the gas flow rate, and the size-pair holes are arranged so as to correspond to the respective gas outflow portions. Then, they are rotated and rotated. Disk 'and every gas flow Out of the unit, the second communication hole is consistent with any of the first communication holes, so that each of the 10 burners on fire and each burner on the lower fire can be set to two positions of strong and weak firepower.

At this time, a rotation angle detecting device 52 is attached to the rotation shaft 51, and the rotation position of the rotary dial 43 can be measured. In addition, a second communication shaft L46 is provided on the rotary disk 43. As shown in FIG. 4, the second communication hole 46 is a long hole in the circumferential direction. The size of the second communication hole 46 is two holes adjacent to the first communication holes 44 a, 44 b, 45 a, and 45 b of the fixed plate 42 at the same time. Consistent, and when changing the firepower, 20 will not simultaneously block the gas passages 14a, 14b of one of the firepower changes, resulting in a pair of large and small L44a, 44b or 45a, 45b. Thereby, the rotating disk 43 is rotated by the motor 5 so that the second communication hole 46 is sequentially aligned with the two 孑 L 44a, 44b, 45a, 45b of the first communication hole, and the state of the burner can be switched cyclically, and its circulation It is from the upper burner strong, lower 11 200302331 玖, the description of the invention, the state of the fire burner is strong, the state of the fire burner is strong, the lower burner is weak, and the upper burner is weak, and the lower burner is weak. The state Γ is finally the state where the upper burner is weak and 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 rotate forward and backward freely. For example, let the control part (not shown) for controlling the operation of the gas valve i 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 disc 43 is determined by the rotation angle of the rotation shaft 51 detected by the rotation angle detection device 52 and the memorized rotation degree, and By rotating the rotary disk 43 in that direction, the fire power of the upper burner or lower burner can be switched quickly and smoothly. In addition, the control switch of the gas range in this embodiment may include, for example, a touch switch for adjusting the ignition / beacon of each of the burner and the burner, and the burner for firing and firing, respectively. Select the strong or weak firepower change to touch 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 can be made to coincide with the large holes 44a and 45a, respectively. In the following, the effects of the gascoal 1 according to this embodiment will be described with reference to Figs. 4 and 5. Since the touch switch of the conditioning start is adjusted to ON, it is easy to ignite the burners of the upper and lower fires. Therefore, the second communication hole 46 and the first communication hole of the rotary disk 43 and the rotary disk 43 are rotated. The big holes 仏, 45a are the same. At this time, the rotation angle of the rotation shaft 51 measured by the rotation angle detection device 52 is 0 degrees. Next, ‘on’ electromagnetic 阙 2.

At this time, fuel gas is supplied to the mixing pipe of each combustion state so that the gas flow rate of each of the burners of the upper and lower fires becomes stronger. Then, the ignition operation of each burner is performed. Here, for example, in order to change the firepower of the lower-burning burner, when the 5th weak-firepower change touch switch is pressed, the control unit corresponding to each of the burners stored in the control unit for controlling the operation of the gas valve 1 is firstly stored. The rotation angle of the firepower 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 corresponding to the upper burner strength of 10 and the lower burner strength to be memorized by the control unit is set to 90 degrees, the motor 5 rotates the rotation shaft 51 in the positive direction shown by ① in FIG. 5. Up to now, the second communication hole 46 of the rotating disk 43 is consistent with 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 rotary disk 43 is rotated, the large hole 44a for keeping the first communication hole of the 15-burning power Aiqiang of the burning burner straightly kept to the second communication hole 46, so that the burner is lit. The firepower will not change. In order to change the fire power of the fired burner in the aforementioned state, when the fire switch with a weak fire power is pressed to change the touch switch (at this time, the rotation angle corresponding to the weak fired burner and the lighted down burner memorized by the control unit is (180 degrees), as with the 20 narrators, 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 second hole 46 and the small hole 44b of the first hole. The rotation angle measured by the angle detection device 52 is 180 degrees, refer to FIG. 4 (c)). In order to change the fire power of the lower-burning burner in the aforementioned state, press the fire power 200302331 玖, description of the invention When the strong fire power changes the touch switch (At this time, the control unit memorizes that the corresponding burner is weak and the lower-burner is burned Strong rotation angle is 270 degrees), it is determined that the rotation direction of the motor 5 is the ① direction, and the rotation shaft 51 ′ of the motor 5 is rotated to the second communication hole 46 and the large hole 45a of the first communication hole until (a 5 The rotation angle measured by the rotation angle detection device 52 is 270 degrees, refer to FIG. 4 (d)). In contrast to the foregoing, in order to change the fire power of the upper fire burner from the weak fire burner and the lower fire burner, the fire power of the high fire power is pressed to change the L-touch switch, because in this embodiment, The control unit memorizes that the rotation angle corresponding to the strength of the upper burner and the lower burner is 90 degrees, so it is absolutely necessary to rotate the rotation axis 5 丨 in the opposite direction as shown in Fig. 5 ②. Then, by means of the motor 5, it is known that: the rotation shaft 51 is rotated to the second communication hole 46 and the large communication hole 45a of the first communication hole 43 of the rotary disk 43 (the rotation angle measured by the rotation angle detection device 52 is 90 degrees, refer to Figure 4 (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 firepower positions for each burner that fires and fires, and can smoothly switch these. Location and can be a low cost producer. [Brief Description of Drawings] 20 Figure 1 is a sectional view of a gas valve of the present invention.
