Description of the Related Art In recent years, a grill integrally formed on a gas stove has been configured as a double-sided grill for the purpose of improving the usability of the grill by eliminating the trouble of turning over the food such as fish placed on the grill during cooking. Is proposed. For this reason, an upper fire burner is provided on the ceiling of the grill and lower left and right burners are provided on both inner side walls of the grill below the grill.

るが、これではコスト高を招く。In this case, an open / close valve for controlling the supply of fuel gas and a flow rate control valve for controlling the gas flow rate of the fuel gas are provided for each burner so that the heat power of each burner for the upper and lower fires can be adjusted independently. Although it is possible to provide a gas valve having the above, this leads to high cost.

For example, the fine squeezing performance is not required unlike the gas burner installed in the stove that cooks simmered food, and it is inconvenient for the cook if two types of thermal power positions can be set for each of the upper and lower fire burners. Don't give.

No. 9312 discloses a gas valve provided with a flow rate control valve having a fixed disk having a first communication hole and a rotary disk having a second communication hole and rotated by a motor. There is. In this type, one gas valve is used to supply the fuel gas to the upper and lower fire burners and adjust the gas flow rate.

弱の２種類の火力ポジションが設定できる。In this case, the four first communicating holes formed in the fixed disk are composed of two holes for increasing the gas flow rate and two holes for decreasing the gas flow rate, and a pair of large and small. Holes are aligned with each gas outflow portion. Then, by rotating the rotary disk, the second gas is supplied to each gas outlet.
By matching the communication hole with one of the first communication holes, two types of thermal power positions, strong and weak, can be set for each of the upper fire burner and the lower fire burner.

に燃料ガスが流れる。However, in the above, the flow control valve has a closing function. That is, a separate through hole is provided in the fixed disk, and the first through the through hole.
The fuel gas flows to the gas outflow portion only while the communication hole and the second communication hole are in communication with each other.

流量を設定できない。For this reason, there is a problem in that the combination of the thermal power positions of the upper and lower fire burners can be only three, and the usability is poor. That is, when using each burner, it is necessary to always make the second communication hole and the through hole coincide with each other, so that, for example, the second communication hole can be adjusted so that the upper flow burner is strong and the lower combustion burner is weak. When the passage is set, the upper heat burner is weak and the lower heat burner is strong. The gas flow rate cannot be set.

However, there is a problem that the cost is increased as a whole.

For example, a control unit (not shown) that controls the operation of the gas valve 1 stores a rotation angle of the rotary shaft 51 corresponding to each thermal power of each of the upper and lower fire burners, and the upper fire burner or the lower fire burner is stored. When any one of the heating powers is changed, the rotation direction of the disk 43 is determined from the rotation angle of the rotation shaft 51 detected by the rotation angle detection means 52 and the stored rotation angle, and the rotation disk 43 is rotated in that direction. As a result, it is possible to quickly and smoothly switch the heating power of the upper heat burner or the lower heat burner.

One of them is provided with a heat power changing touch switch for selecting strong or weak, respectively. When the upper and lower fire burners are ignited, the second communication hole 46 of the rotary disk 43 is set to the large hole 44a,
It is better to match with 45a.

In this case, the fuel gas having a gas flow rate for increasing the heating power of each of the upper and lower burners is supplied to the mixing pipe of each burner. Then, the ignition operation of each burner is performed.

When the heat power change touch switch of the heat power is pressed, in the present embodiment, the rotation angle corresponding to the upper heat burner strong and the lower heat burner weak stored in the control unit is 90 degrees. It is decided to rotate the rotary shaft 51 in the direction. Then, in the motor 5, the rotation shaft 51 causes the second communication hole 46 of the rotary disk 43 to be the large hole 45 of the first communication hole.
It is rotated until it coincides with a (rotation angle 90 degrees by the rotation angle detection means 52, see FIG. 4B).
