Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a gas burner in which gas flame holes are provided in two stages, upper and lower.

[Background technology] This type of gas burner burns the gas with high combustion efficiency by mixing the gas sent from the gas supply pipe and the air sucked in from the air intake port at a constant ratio in the mixing pipe. It is. However, when cooking requires high calories, such as when cooking vegetables, for example, there is a drawback that cooking takes a long time. To solve this problem, increasing the amount of gas supplied and increasing the diameter of the air suction port to increase the amount of air required for combustion does not allow uniform mixing of gas and air in the mixing tube. There were limits to the amount of heat generated, such as the inability to miniaturize the device.

[Purpose of the invention] The present invention has been made in view of the above points, and it increases the calorific value of combustion gas to enable cooking that requires high calories to be done in a short time, and also reduces the discharge amount of mixed gas. An object of the present invention is to provide a gas burner that can be adjusted and can achieve stable combustion.

[Disclosure of the invention] That is, the present invention partitions the space inside the burner body A, which is formed by fitting the burner head 9 in the form of a cap into the burner body 13, with the horizontal shielding plate 18, and divides the space inside the burner body A into the upper and lower parts. A mixing chamber 22 and an auxiliary mixing chamber 23 are formed, and a main flame hole 10 communicating with the main mixing chamber 22 is provided on the outer periphery of the burner body A, and an auxiliary flame hole 11 communicating with the auxiliary mixing chamber 23 is provided at one end. The mixed gas discharge port 3 at the other end of the main mixing pipe 4, in which the gas supply port 1 and the air suction port 2 are formed, is communicated with the main mixing chamber 22 in the burner body A, and the gas supply port 5 and air inlet are provided at one end. The above object is achieved by a gas burner in which a mixed gas discharge port 7 at the other end of an auxiliary mixing pipe 8 in which a suction port 6 is formed is communicated with an auxiliary mixing chamber 23 within a burner body A.

The present invention will be explained in detail below with reference to the embodiments shown in FIGS. 1 and 2. The main mixing pipe 4 is formed in a cylindrical shape, and the lower end of the main mixing pipe 4 has a gas supply port 1 and an air suction port 2.
is formed, and a mixed gas discharge port 3 is formed at the upper end. The auxiliary mixing tube 8 is also formed into a cylindrical shape having approximately the same shape as the main mixing tube 4, and a gas supply port 5 and an air suction port 6 are formed at the lower end of the auxiliary mixing tube 8, and at the upper end. A mixed gas discharge port 7 is formed. The burner body A is formed by fitting a cap-shaped burner head 9 into a burner body 13, and by partitioning the space inside the burner body A with a horizontal shielding plate 18, a main mixing chamber 22 is formed above and below inside the burner body A. An auxiliary mixing chamber 23 is formed. The main mixing pipe 4 and the auxiliary mixing pipe 8 have their lower ends fixed to the mounting board 12, and their upper ends fitted into the insertion holes 14 and 15 of the burner body 13 of the burner body A, so that they are arranged and fixed in parallel. The gas supply pipes 16 and 17 are connected to the respective gas supply ports 1 and 5 to connect the gas supply pipes 16 and 17 to the respective gas supply ports 1 and 5.
The gas from 7 is supplied into the mixing tubes 4 and 8. At this time, air is sucked into the mixing tubes 4, 8 from the air suction ports 2, 6 by the flow of the supplied gas, and the gas and air are mixed uniformly in each mixing tube 4, 8. be. On the outer periphery of the burner head 9 of the burner body A, an auxiliary flame hole 11 in the upper stage and a main flame hole 10 in the lower stage are provided respectively through a shielding plate 18, and the burner head 9 is fitted into the burner body 13. When assembled, the auxiliary flame port 11 communicates only with the mixed gas discharge port 7 of the auxiliary mixing pipe 8 via the auxiliary mixing chamber 23, and the main flame port 10 communicates with the main mixing chamber 2.
2, it communicates only with the mixed gas discharge port 3 of the main mixing pipe 4. In the figure, 19 is a soup saucer, 20
21 is a boiling-over prevention ring cover, and 21 is a shielding plate mounting piece fixed to the auxiliary insertion opening 15 of the burner body 13.

However, when performing high-calorie combustion with the lever gas burner, the gas tanks of the respective gas supply pipes 16 and 17 are opened and gas and air are supplied to the main mixing pipe 4 and the auxiliary mixing pipe 8 and mixed uniformly. The mixed gas, which is a mixture of gas and air, is passed through the mixed gas discharge ports 3 and 7.
By discharging a large amount of mixed gas through the main flame hole 10 and the auxiliary flame hole 11, high-calorie combustion can be performed. In addition, when suppressing the calorific value of the gas burner, one of the gas supply pipes 16 and 17 connected to the main mixing pipe 4 or the auxiliary mixing pipe 8 may be used, for example, the gas supply pipe connected to the auxiliary mixing pipe 8. 17 is twisted to stop the gas supply, and gas is supplied only to the main mixing pipe 4. Main mixing pipe 4
The gas supplied into the main flame hole 1 is mixed with air and
It is possible to discharge a mixed gas from zero and perform low-calorie combustion. Here, main flame hole 10
is shielded by the auxiliary flame hole 11 and the shielding plate 18, so that complete combustion can be performed without air being sucked in from the air intake port 6 of the auxiliary mixing tube 8 and changing the mixing ratio of gas and air. It is something.

[Effects of the invention] As described above, the present invention includes a main mixing pipe in which a gas supply port and an air suction port are formed at one end and a mixed gas discharge port at the other end, and a gas supply port and a gas supply port at one end. an auxiliary mixing tube having an air suction port and a mixed gas discharge port formed at the other end; Since the auxiliary flame holes that communicate only with the mixed gas discharge ports are provided, the gas and air supplied to the main mixing pipe and the auxiliary mixing pipe are mixed independently in the mixing pipes, so that each A mixed gas in which gas and air are evenly mixed in the mixing tube can be discharged from the main flame hole and auxiliary flame hole, and high calorie combustion can be performed. Even if the cooking requires a lot of time, it can be done in a short time. Also, even if you twist the gas supply pipe of either the main mixing pipe or the auxiliary mixing pipe to mix gas and air in one mixing pipe, excess air will flow from the air intake port of the other mixing pipe. It is possible to always discharge a mixed gas in which gas and air are mixed at a constant ratio without being inhaled, and it is possible to adjust the discharge amount of the mixed gas in a state where complete combustion is achieved. Furthermore, the space inside the burner body, which is formed by fitting a cap-shaped burner head to the burner body, is partitioned with a horizontal shielding plate to form a main mixing chamber and an auxiliary mixing chamber above and below the burner body. A wide main mixing chamber and an auxiliary mixing chamber are formed extending from the center to the outer periphery of the burner body, and the mixed gas supplied from the main mixing pipe and the auxiliary mixing pipe is even better in the main mixing chamber and the auxiliary mixing chamber. It is mixed and flows uniformly to the main flame hole and auxiliary flame hole on the outer periphery, and combustion in the main flame hole and auxiliary flame hole is performed stably. The main mixing chamber and the auxiliary mixing chamber can be connected to each other at a position close to the periphery, and the mixed gas can be uniformly supplied to the main flame hole and the auxiliary flame hole on the outer periphery to achieve stable combustion.
