The simplification of the ignition operation provides a number of benefits, including the convenience of use.

In general, the gas burner uses a valve mounted at one side to supply and shut off the gas to ignite the gas by ejecting the gas into the ejection hole of the gas burner. Such a conventional gas burner is ejected to the ejection hole side of the ignition unit as shown in FIG. In order to supply gas, valves are individually installed on each supply pipe side to open and close them. Hereinafter, the problems of the conventional articles will be described in detail.

Conventional gas burners have two or three separate valves for controlling the supply of gas to each gas supply pipe in one burner. There was an inconvenience in using the ignition, and it is difficult to determine exactly how much of the initial gas supply for ignition, especially in the case of the immature. When food was severely overflowed or extinguished by strong wind during use, it could not be equipped with a gas supply shutoff device for safety, causing gas leakage and causing a safety accident.

The applicant has already filed an application (Utility Model Registration Application Nos. 94-4012 and 95-2806) to solve such problems and to promote convenience and fuel saving. There was a risk of safety accidents due to gas leakage, and it was difficult to achieve the gas supply more precisely, and it was also difficult to perform the gas supply of the ignition gas supply pipe with one handle operation.

The present invention as described above is to obtain a variety of advantages, such as the simple ignition operation of the gas burner (1) and to prevent safety accidents due to gas leakage, that is, the present design is the first operation of the handle (7) The gas is supplied to the ignition gas pipe 17, and in this process, the opening and closing hole 24 of the supply path 15 is opened, while the supply pipes 3 and 3 through both supply nozzle pipes 8 and 8 ′. Since the gas supply on the ') side can be selectively adjusted, the gas supply amount can be freely adjusted and fuel saving effect can be obtained from the gas supply part. Also, a safety device is built into the gas supply part 22 so that the ignition part 2 is provided. When extinguishing, the safety device is built in the gas supply unit 22, and when the ignition unit 2 is extinguished, the opening and closing hole 24 on the supply path 15 of the gas supply unit 22 is automatically blocked by the breaker 10. To prevent safety accidents due to gas leakage, Looking at the operation method and the effect according to the present invention in detail as follows.

2 is a cross-sectional view showing an operating state of the present invention, FIG. 3 is a cross-sectional view showing an operating state of the gas supply unit 22, and FIG. 5 is a longitudinal cross-sectional view showing an operating state of the present invention. As shown in FIGS. 2 and 3 and 5 (a), the dividing hole 134 and the dividing hole 133 on the front sphere 13a of the ball body 13 in which the flow hole 131 is formed are divided into branching lines ( And the rear spheres 13a and 13b are not in communication with the supply passage 15, and the rear spheres 13a and 13b are not in communication with the supply passage 15. ) Is a state in which the supply port 132 is not in communication with the supply path 15, that is, only open to the ignition gas pipe 17 side.

The ball body 13 is in the basic state as described above unless the handle 7 is operated.

In this basic state, the handle 7 is pushed and rotated toward the valve body 6 so that gas is started and at the same time, the ignition unit 2 is ignited from the auto igniter 9. (3,3 ') to enable the supply of gas.

This is to first push the handle (7) in the basic state to rotate the handle (7) in the counterclockwise direction, when pushing the handle (7) as shown in the second (b), third (b) The breaker 10 in which the pushing shaft 26 on the 7) is pushed and the pushing shaft 26 inserted into the intermittent hole 25 seals the opening and closing hole 24 formed in the connection path 23 of the supply passage 15. The opening and closing hole 24 is opened by pushing the blocking plate 10b.

And at this time, the remains 21 of the handle (7) is fully inserted into the rotation shaft 14 and the spring 20 is in a compressed state, when the handle 7 is pushed in the pushed state, the center road (11) In the rear spherical body 13b of the ball body 13 installed in the c), the supply port 132 communicates with the supply passage 15 and the ignition gas pipe 17 to supply a small amount of gas to the ignition pipe 29 of the ignition part 2. At the same time, the handle 7 is connected to the igniter 9 by pressing the pushing knob 9a installed on the igniter 9 above the valve body 6 together with the pushing of the pushing shaft 26 in the pushing process. Spark ignition is to be made from the spark (30) of the ignition unit (2).

Therefore, a gas is supplied from the ignition gas pipe 17 so that the igniter can be made on the first ignition part 2, and the spark 30 is connected to one end of the ignition pipe 29 connected to the ignition gas pipe 17. When the first handle 7 is pushed and rotated about 45 ° in the counterclockwise direction, the opening / closing hole 24 sealed by the blocking pin of the circuit breaker 10 is opened as described above. The gas is supplied to the ignition tube 29 of the ignition gas tube 17 through the 15, and the pushing knob 9a of the igniter 9 is operated to cause the spark ignition from the spark 30. Ignition of the gas burner 1 is simplified.

In this state, when the handle 7 is rotated about 45 ° counterclockwise again, the splitting hole 133 formed on one side of the front sphere 13a communicates with the side branch passage 12 and the gas burner 1 It is to supply gas to one side of the supply pipe (3), at this time the gas is already supplied through the ignition gas pipe (17) and the ignition unit (2) is in the ignited state through one side branch (12) By only supplying gas, more active ignition of the ignition unit 2 is achieved.

When the handle 7 is rotated further by about 45 ° counterclockwise, the division hole 134 formed on the front sphere 13a of the ball body 13 communicates with the other branch path 12 '. Since a larger amount of gas is supplied through both supply pipes 3 and 3 'to the ignition unit 2, the thermal power of the ignition unit 2 is counted. In this case, as shown in FIG. The supply port 132 of the rear sphere 13b communicating with the furnace 15 and the division port 133 and the division hole 134 communicated with each other by the supply port 132 and the distribution hole 131 are mutually connected. In communication, gas is supplied to the supply pipes 3 and 3 'through both branch paths 12 and 12'.

Therefore, it is possible to freely adjust the supply amount of gas as well as the ignition operation only by the simple operation of the handle (7), thereby obtaining a fuel saving effect, and in addition to ensuring the convenience of using the gas burner (1).

In the process, the ignition gas pipe 17 is continuously supplied with gas from the supply port (! 32) in communication with the supply passage 15, so that the ignition state of the ignition pipe 29 can be maintained continuously. The breaker 10 for controlling the opening and closing hole 24 of the supply path 15 is connected to the heat sensor 31 of the ignition unit 2 so that the ignition unit 2 is automatically extinguished during gas supply. Bar is to interrupt the opening and closing the gas supply bar, which will be described in more detail below.

In the pushing operation of the handle 7, the blocking plate 10b, which has closed the opening and closing hole 24 by the pushing shaft 26, is separated from the opening and closing hole 24 so as to be extruded by the spring 10a. In addition, when the ignition part 2 is in the ignition state, the blocking plate 10b in the compressed carbon state is detected by the heat detection sensor 31 installed in the ignition part 2 by the heat. ) Is maintained in a compressed carbon state to keep the opening and closing hole 24 in a continuous open state and to continuously induce the supply of gas to continue the ignition of the ignition unit 2, when the ignition unit 2 is extinguished The blocking plate 10b, which was automatically supported by compression springs in the spring 10a, is not able to detect heat by the heat sensor 31, so that the blocking plate 10b is pushed toward the opening and closing hole 24 to seal it. do.

Such a bimetallic automatic gas supply shutoff device is common.

In this way, the present invention is to break the conventional bimetallic automatic gas supply shutoff device to the valve body (6) when the ignition unit (2) is extinguished due to outside air or other carelessness during the supply of gas, the thermal sensor 31 Detects this and pushes the blocking plate 10b compressed by the spring 20 to close the opening and closing hole 24, thereby stopping the supply of gas, thereby preventing further gas supply to the ignition unit 2, thereby preventing the gas. Be prepared for safety accidents caused by leaks.

When the gas burner 1 is extinguished and the gas supply is cut off, when the handle 7 is rotated clockwise to return to its original position, the ball body 13 returns to its original position to supply gas through the central path 11. It will be blocked, leaving it in its default state.

As described above, the present invention can easily and smoothly guide the gas supply cutoff in three directions of the ignition gas pipe 17 and the supply pipes 3 and 3 'of the branch paths 12 and 12' by operating one handle 7. As a result, the convenience of using the gas burner 1 is increased, and the gas supply amount can be freely adjusted. When the ignition unit 2 is extinguished while the gas is being supplied, the gas supply is automatically shut off, resulting in a safety accident due to gas leakage. Being able to prevent in advance, it is an extremely excellent design that the expected effect is expected.

The scope of the technology to be particularly protected in the present invention will be described in the following appended claims for utility model registration, but similar variations, such as changing the shape of some constituent members or replacing them with equivalents, may be used. As long as they work together to solve the problem, they belong to the same technology category as the present invention.
