Fire safety system for portable gas ranges {A safety system for portable gas range}

The present invention relates to a fire extinguishing safety device for a portable gas range 100, and when using the portable gas range 100, the broth overflows, the wind blows or inadvertently extinguish the flame of the burner 20 In order to prevent the gas from continuing to flow out, the thermocouple 10 is located on one side of the burner 20 to sense whether the spark is ignited, and the magnetic force is generated by the thermoelectric power generated from the thermocouple 10. The magnet blocking device 30 which can open the passage of the gas is configured inside the body 50 of the burner 70, and when the flame of the burner 20 is extinguished, the gas supply is automatically shut off. It relates to a fire-fighting safety device of a portable gas range 100 that can prevent accidents caused by.

In general, the portable gas cooker 100 is a portable cooking utensil used for simply grilling meat or heating cooking utensils in the outdoors or indoors. In order to reduce the risk of accidents, various safety devices have been developed.

In the conventional portable gas range 100, when the gas container 5 is mounted at the inlet 71 of the governor 70, the gas in the gas container 5 is reduced in the pressure reducing chamber 73 through the pressure reducing chamber inlet 72. When the gas decompressed by the gas flows into the gas volume control chamber inlet 75 which is in communication with the decompression adjustment chamber outlet 74, the gas volume control chamber inlet 75 is opened by the gas volume control device 120. The flame is ignited by moving to the burner 20 through the gas discharge pipe 21 which flows into the chamber 76 and communicates with the gas amount control chamber 76.

However, the gas container 5 when the inlet 75 is opened by the gas amount adjusting device 120 and the broth overflows, the wind blows, or the flame of the burner 20 is inadvertently extinguished by the user. The gas inside is continuously moved to the burner 20 and flows out. In general, the gas in the gas container 5 used in the portable gas range 100 is liquefied petroleum gas (LPG), so that the specific gravity is heavier than air, and most of the gas leaked into the burner 20 is inside the portable gas range 100. Accumulate. Therefore, when the leaked gas reaches the explosion threshold concentration, there is a risk that the accumulated gas is exploded at the moment of pressurizing the piezoelectric element 9 for ignition or ignition of the surroundings, causing a safety accident.

Fire extinguishing safety device of the conventional portable gas range 100 was developed in order to solve the above risk, apart from the body 50 of the governor 70, the magnet blocking device 30, opening and closing pins 60, spring ( 62), a separate housing is formed to form the washer 63 and the sealing ring 64, so that the gas inlet 52 of the magnet shut-off device chamber 54 is connected to the decompression adjustment chamber 73 and the gas is discharged. The gas outlet 51a of the chamber 51 was connected in communication with the gas volume control chamber 76 to solve the problem by coupling a separate housing to one side of the body 50 of the governor 70. However, such a conventional fire extinguishing safety device has a factor of the hassle and cost of having to manufacture a housing separately from the body 50 of the governor 70, and a flow path configured in the body 50 of the governor 70 Separate sealing rings and screws are required to connect and combine the flow paths formed in the housing, which increases cost as well as increases the assembly process. In addition, a separate gas leakage test is to be added to check for gas leakage at the joints of the flow path.

Therefore, when the portable gas range 100 is used, when the broth overflows, the wind blows, or the user inadvertently extinguishes the flame of the burner 20, the flow path is automatically opened in the body 50 of the governor 70. It is required to develop a fire extinguishing safety device of a cheaper and more reliable portable gas range 100 that can be blocked to prevent the gas from continuously flowing out.

The present invention is invented to solve the above problems, the purpose of which is that when the use of the portable gas range 100, when the broth overflows, the wind blows or the user carelessly extinguish the flame of the burner 20 It is configured to automatically block the flow path in the body 50 of the governor 70 so as to prevent the gas from continuously leaking to the outside, and develop a cheaper and more reliable fire extinguishing safety device, resulting in a safety accident due to gas leakage. To prevent it.

In particular, the fire extinguishing safety device of the portable gas stove 100 is configured inside the body 50 of the governor 70 without any additional device, thereby reducing the number of parts and the manufacturing process, while lowering the production cost. Flow and tightness are aimed at developing a more complete fire protection system.

In order to achieve the above object, the present invention, the magnetic shield device chamber 54 and the gas discharge chamber 51 is formed in communication with the body 50 of the governor 70, the magnet shield device room ( 54 is formed in the gas inlet 52 in communication with the gas volume control chamber 76, the gas discharge chamber 51 forms a gas outlet 51a that can be connected to the gas discharge pipe 21, the magnet blocking The magnet blocking device 30 is inserted into the device chamber 54, and the thermocouple 10 connected to the magnet blocking device 30 is fixed to one side of the burner 20 to generate the thermocouple 10. It relates to a fire extinguishing safety device of a portable gas range 100, characterized in that the opening and closing of the gas passage depending on whether the burner 20 is ignited / extinguished by a magnet blocking device that generates magnetic force by the thermoelectric power.
