Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to the formation of a flame mouth type by placing a burner head with a flame mouth groove on the body of the burner Gas burner used. [Known technology] The fire power of the conventional gas furnace burner for reducing weak fire is about 0.465 kW (400 kcal / hour). When the fire is weak, the fire will be turned off, or there will be tempering on the side of the gas distribution room. The backfire phenomenon β Figure 5 shows an example of a conventional burner head (It is fair 4-61246) that Yiyuan improves the flame stability and prevents backfire in a weak fire, a series burner head, b series gas distribution road, The c-type flame mouth groove forming portion is provided with an inner peripheral protrusion d on its inner peripheral side, and an outer peripheral protrusion e provided with a phase shifted from the inner peripheral protrusion d on the outer peripheral side, and an inner peripheral side passage dl is formed between the inner peripheral protrusions d and d. A flame groove 61 ′ is formed between the peripheral protrusions e and e. A shallow auxiliary flame groove center is provided on an end surface of the peripheral protrusion e. This burner head a has a large non-linear passage resistance between the inner peripheral side passage d1 and the flame mouth groove ei. As a result, the outflow speed is suppressed when the gas supply is excessive, and the flame is prevented from returning when the gas supply is reduced. In the direction of arrow f, the minimum supply of gas can be made small. In addition, g is at the inner flame port. However, since the burner head a is provided with two rows of protrusions d and e in the groove forming portion (^ throughout the entire circumference), the structure is complicated, and it is difficult to apply the burner head having a small diameter in terms of size. In addition, since the flame mouth grooves e1 all have a deceleration effect, the amount of change in the strength of the flame cannot be made large. [Problems to be Solved by the Invention] The present invention is to obtain a simple means of increasing the conventional knowledge, and to increase the effect of reducing the firepower.

Description of the invention (2) A7 B7_____ device as the subject. [Means for solving the problem] The means for solving the above-mentioned problems are as the application The first item of the patent scope is that a gas distribution path and a flame opening and groove forming portion are provided on the inner and outer layers of the burner head. The flame opening and groove forming portion is provided in a radial shape to form the flame opening and groove. Part It is placed on two parts of the ring-shaped supporting surface of the burner body, thus forming a flame burner for a gas furnace. Among them, it is slightly the same as the depth of the flame mouth groove. The stable flame mouth groove with a large width and short length is provided at a plurality of flame mouth groove forming portions of the burner head, and a plurality of narrow inflow grooves in the middle of the stable flame mouth groove are connected in the periphery of the stable flame mouth groove. Feature 0 In this burner, when the reduced gas is a weak fire, even if the combustion of the flame mouth other than the stable flame mouth becomes unstable, the fire is moved from the stable flame mouth to the other flame mouth due to the stability of the flame stability of the flame mouth. Stabilize the combustion. Furthermore, even if a backfire phenomenon occurs in the stable flame mouth during a weak fire, the resistance of the partition wall in the stable flame mouth to the backfire can suppress the backfire. [Embodiments of the Invention] Hereinafter, the invention will be described with reference to the drawings. Embodiment 1.

Description of the invention (3) A flame opening 7 is provided, and an ignition section 8 is set in part. The flame mouth groove forming portion 5 is provided with six fire-breathing mouthpieces 10 at slightly equal intervals except for the portion of the ignition portion 8. The width of the stable flame groove 10 is W, and the length is L. The width W of the stable flame is 2 to 3 times the width of the flame groove 6, and the length L is a half of the length of the flame groove 6. The stable flame groove 10 is Two inflow grooves 12 and 12 are formed on the inner peripheral side via the partition wall U. 13 in the figure inserts the protection tube of the temperature sensor outside the figure into the center hole of the burner B from below. As shown in FIG. 4 'When the burner head 1 is installed on the burner body 2 which is conventionally used, and the burner B is formed', the gas distribution path 4 and the inductive path 14 of the burner 2 are used to form a distribution room. 4A, flame mouth groove 6, auxiliary flame mouth groove 7, stable flame mouth groove 10 and inflow groove 12 together with the support surface 15 of the burner body 2 form a flame mouth 6A, auxiliary flame mouth 7A ', stable flame mouth 10A and inflow inlet 12A. The stable flame port 10a of the burner B has a large groove width w, and the length of the edge portion around the outlet of the flame port becomes longer, thereby improving flame stability. In addition, since the length L is short, the passing resistance within the stable flame port 10 is small, and the change in the flame is moderated when the gas valve is operated, and the flame will not be turned off even during a sudden weak fire operation. Furthermore, the low-fire performance is improved and the heat retention of the cooked product is improved. The thermal insulation test to ensure the thermal insulation performance was to add 1000 ml of water at a diameter of 20 cm in diameter, and boil over medium heat, hold it for 5 minutes with a low fire, and use the weight at that time as the initial weight. The weak fire continued for 1 hour. Post-investigation test to test the amount of evaporation 'to test the conditions of gas 13A-1, gas pressure of 2.0 kPa (Pascal), and the use of a burner with a minimum firepower of 0.29 kW (250 kcal / hour). ) A4 specification (210 X 297 public love) --II ----- 1 III · 1111111 ^ --- IIIII i · < Please read the precautions on the back before filling in this page) 6 Ministry of Economic Affairs 1 A7 printed by the Bureau of Work and Consumer Cooperatives _______B7 V. Description of the Invention (4) The conventional burner is a burner B with a graphic representation of 180 grams with a minimum throttling of 0.465 kW (400 kcal / hour). , The firepower can be throttled at 0.29 kcal / hour), and the evaporation amount of the firepower is 70 grams. In this test, the amount of evaporation was 70 g. 6 In this test, the 'evaporation amount was reduced by 61%' and the firepower was reduced by 37 50/0. In this way, because the reduction of evaporation is greater than the reduction of ignition power, the evaporation of water is reduced during weak fires, which is suitable for holding together or holding β. Furthermore, the foregoing section before and after 0.29 kW (250 kcal / hour) In this case, the backfire phenomenon as shown by the arrow f was not generated at all. This can be explained by the resistance to the countercurrent caused by the partition wall 11. In addition, although the aforementioned burner has the auxiliary flame port 7α, a burner without the auxiliary flame port can also produce the same effect. [Effects of the invention] From the above description, it is clear that a stable flame port is provided as a stable flame port, and the depth is slightly the same as the groove width and the length of the stable flame port is short. The longer the length of the edge of the flame can improve the stability of the flame ', because the length of the stable flame mouth is short and the passing resistance is reduced, the flame change can be eased, even if the fire operation is sharp, it will not recall the fire. The resistance of the side wall has the effect of preventing backfire. In addition, since the stable flame openings are provided at a plurality of burners, there is an advantage that the stable flame action can be reliably performed.
