Description of the Related Art Conventionally, when cooking various dishes, it is necessary to adjust a wide range of heating power according to the cooking, but a single burner cannot cover a wide range of heating power required for cooking, and therefore a high heating power is required. It is known to have a two-mouth stove equipped with a large burner designed to obtain sushi and a small burner designed to obtain a low heat (hereinafter referred to as "torohi") suitable for cooked dishes. In other words, a large burner extinguishes without forming a flame at the mouth when it is simmered, and a small burner causes incomplete combustion when burned with strong heat, so a large burner and a small burner are provided on the left and right, depending on the dish. I'm using different burners. Further, as shown in FIG. 5, a child burner 35 designed for low heat and a parent burner 31 designed for high heat are provided in the central part in a combined manner, and by using them in combination, the heat power adjustment range can be obtained. There is known a parent-child burner 30 having a wide range.

必要となる等の問題があった。However, in the former two-mouth stove, it is troublesome and inconvenient for the user to selectively use the large burner and the small burner depending on the food. The latter parent-child burner 30 is a combination of an independent large burner and a small burner, and has a wide range of adjustment of thermal power, but the switch for supplying the fuel gas to each burner, the nozzle and the gas amount are adjusted. Since it requires a heating power regulator to operate, the structure becomes complicated, and since each has a burner body and a burner head, the number of parts is large and the productivity is poor. In addition, flame 31 of parent and child burner
Since a and 35a are separated, the flame transfer between both flames 31a and 35a is bad. Moreover, the thermocouple 3 of the safety device that disappears
Since there is no place where 6 can be used as both parent and child flames 31a and 35a and can be detected, only the flame 35a of the child burner 35 is exposed, so that misfire of the parent burner 31 cannot be detected. If it is attempted to detect the misfire of the parent burner 31 by avoiding this, there is a problem that the flame 31a of the parent burner 31 also needs another thermocouple.

いく。Further, when the gas amount adjusting knob is adjusted from low heat A to high heat, the laminar air-fuel mixture flowing through the mixing pipe 4 becomes a turbulent state at a predetermined position B and flows into the side pressure equalizing chamber 35. As a result, the air-fuel mixture is ejected from the first flame port array 38 and the flame is transferred to the second flame port array to ignite. Further, since the first flame port array 38 and the second flame port array 39 are vertically close to each other, the flame is satisfactorily transferred. Then, the flames of both flame mouths gradually increase to the point C of high heat.

る。At the inlet of the upper pressure equalizing chamber 36, the resistor 3
4 is provided and the flame opening area of the second flame opening row 39 is smaller than the flame opening area of the first flame opening row 38, the second flame opening row is adjusted when the heating power is adjusted to the maximum by the needle valve 24. The flame of 39 burns with a smaller amount of combustion than the first flame port array 38.
In addition, the flame ignited in the air-fuel mixture ejected from the second flame port row 39 transfers to the entire circumference of the second flame port array 39 and also transfers to the first flame port array 38 to form a flame. The fire transfer at this time is very good because the upper and lower two rows of flame openings are formed and the flames at the respective flame openings are vertically and horizontally adjacent to each other. Also,
As shown in FIG. 2, the heating power adjustment range of the stove burner 30 covers a wide range (maximum c to minimum a) obtained by combining the adjustment ranges of the combustion amounts of the first flame port array 38 and the second flame port array 39, Adjustable from high heat to low heat. In other words, from stir-fried dishes such as yakisoba or Chinese dishes that require strong firepower to boiled dishes that use simmering fire, it is possible to cook with the same burner.

といったことは防止される。As described above, according to the gas cooker of the present invention, the gas burner 30 is controlled by the gas amount adjusting knob 15.
When the predetermined supply gas amount b is reached by adjusting the supply gas amount to the upper side to the lower side, the supply of the air-fuel mixture to the side pressure equalizing chamber 35 is stopped and is supplied only to the upper pressure equalizing chamber 36. Therefore, the combustion limit gas amount of only the second flame port array 39 can be narrowed down. Further, since the second flame port array 39 of the upper pressure equalizing chamber 36 is formed with a small flame port, the combustion limit gas amount can be further reduced. Therefore, even if a burner with a large capacity can cook boiled dishes, it can be squeezed to low heat. Further, it is not necessary to provide two independent switches and a thermal power regulator such as a parent-child burner, and a simple configuration may reduce the number of parts, thereby improving productivity. In addition, the second flame row 39 is
Since it is provided at a position close to and above the flame port array 38, even if the switching point is slightly displaced and unburned gas leaks from the first flame port array 38, it is burned by the flame of the second flame port array 39. Therefore, the unburned gas is prevented from diffusing around the stove.
