C Ming Nai 3 5 1235811 Disclosure of the Invention Problems to be Solved by the Invention To use a plurality of gas burners with such a large number of gas burners, you must use more watts in order to make a gas pipe. Furthermore, due to the gas furnace 5. Second, the structure of the gas volume regulator 55 is operated in the ground. Therefore, the operation must be connected with the operation H53, so _ to adjust the volume ^ must be 55. The operator 53 is located at the gas furnace%. The gas valve is located at the rear. The corner of the gas supply mouth 56 fish two sides. As a result, it would be too long to use 57 to match the officer. In addition, in order not to cause gas pressure loss, the gas piping 57 must be thickened to compensate for the increase in gas piping. The bending of a large pipe is more difficult than the smaller diameter pipe: = manufacturing cost. The object of the invention is to provide a gas furnace which can suppress the thickening of the gas piping and downsize the overall shape. Means for Solving the Problem In order to achieve the above object, the invention described in the first aspect is to install a large number of large burners and a single small burner in the gas furnace. In addition, Yu, +, and Tao Haoyi are placed in the left and right positions inside the gas furnace body, and the small burner is arranged 20 with its center behind the line connecting the center of the large burner on the left and right. Further, each of the electrically driven control units for supplying gas to each of the aforementioned burners is arranged in a linear region along the rear or side of the gas furnace. In the present invention, since the electrically driven control valve is arranged in a linear area along the back or side of the gas furnace, it is possible to shorten the relatively large gas piping that supplies gas to most 1235811 burners without generating gas pressure loss. length. The invention described in the second aspect is the invention described in the first aspect, in which the small burner is arranged between the five large burners in the left-right direction among the large burners. In order to place a conditioning container of a certain size in the large burner, the two large burners are arranged at a certain interval, so that a space can be vacated between the two large burners. In the present invention, a small burner is arranged in the space between the two large burners. In addition, the control valves of these burners are arranged in a linear area along the back or side of the 10 gas furnace, so the gas furnace can be further miniaturized. In particular, since the control valve is not arranged in a narrow lateral space where three burners are arranged side by side ', and is disposed behind the gas furnace, the space can be effectively used. The invention described in the third aspect is the invention described in the first or second aspect, wherein the gas introduction ports of the large burners are arranged to face each other. In order to place a conditioning container of a certain size in a large burner, the two large burners will be arranged at a certain distance, so there can be space between the two large burners. In the present invention, since the gas mixing tube of the two large burners is located in the space between the two large burners, the size of the gas 20% furnace can be further reduced. The invention described in the fourth aspect is that a large number of large burners are installed in the gas furnace, and the large burners are arranged at the left and right positions in the gas furnace body. At the same time, the gas inlets of the large burners are arranged to face each other. Further, each electrically driven control valve 1235811 for supplying gas to each of the aforementioned burners is disposed on a linear area along the side of the gas furnace. In the present invention, since the large burners are arranged on the left and right, and the gas mixing pipe is arranged in the space between the two large burners, it is possible to avoid an unnecessary increase in the width inherent between the large burners, and even if the The control valve is arranged in a straight 5 line on the right or left edge, and the burner or control valve can also be accommodated in a gas furnace with limited width. According to the present invention, it is possible to suppress the thickening of the gas piping and reduce the overall shape of the gas furnace.

Further, on the glass top plate 12, fire power display signs 31A to 31F are formed on both sides of the aforementioned fire power display lamps 29A to 29C by printing or coloring. In addition, based on the number of lighting indications of the firepower display lamps 29A to 29C between the firepower display signs 31A to 31F, it is possible to confirm the firepower adjustment state 20. In Fig. 5, the thickness of the operating portions 30A to 301 is increased in thickness for easy understanding. However, the thickness of the operating portions 30A to 301 does not actually exist. As shown in Fig. 6, one of the large burners 14a is arranged on the left side in the main body case 11, and the gas introduction port HAD thereof is directed to the right and diagonally forward. The other large burner 14B is arranged on the right side in the main body box 11, and its gas guide 11 I2358li inlet 14BD faces to the left. Therefore, the gas inlets 14AD and 14BD of the two large burners 14A and 14B face each other approximately.
