In more detail, the auto shut-off device 30 includes an auto shut-off controller 37, a pressure sensor 31, a shutoff valve 35, a temperature sensor 33, and the like. The pressure of the gas flow path in the gas hose and the gas range 10 is converted into an electric signal and transmitted to the cut-off controller 37. In addition, the auto shut-off controller 37 receiving the electrical signal of the pressure sensor 31 determines the opening or closing of the shut-off valve 35 by determining this ("Automatic shut-off device for preventing gas misuse). (30) ") through this to open or close the shut-off valve 35 only by the operation of the gas range 10, to check the gas leak and fine gas leakage of the gas range 10, and if the fine gas leakage occurs The 35 is completely blocked so that the shutoff valve 35 is not opened even when the gas range 10 is operated.

At this time, the electrical signal is transmitted to the hood controller 27 in real time by the shut-off controller 37, and automatically cuts off when the temperature of the temperature sensor 33 reaches a predetermined high temperature. The shut-off valve 35 is completely blocked to prevent misuse of the gas range (10).

In addition, as described above, the gas range 10 is connected to the gas hose and the gas range controller 13 is additionally configured. The gas range controller 13 confirms the ignition and extinguishing of the gas range 10 by an electric signal. Like the car controller 37, a timer may be built in, or when built in, the gas range 10 may be extinguished by directly receiving an electric signal. In addition, the gas range controller 13 transmits an electrical signal such as ignition and fire extinguishing of the gas range 10 to the car shut-off controller 37 of the car shut-off device 30. The car shut-off controller 37 has been described above. Similarly, the electrical signal and the electrical signal of the pressure sensor 31 and the electrical signal of the flow rate measurable sensor 41 to be described later are compared and analyzed to control the shutoff valve 35.

The hood filter 28 of the range hood 20 may be clogged with foreign matter generated when cooking food, or foreign matter may enter the exhaust pipe connected to the hood exhaust fan 21 to block the exhaust fan motor 211. This is because when the hood filter 28 is blocked at the same rotation speed, the exhaust pressure is lowered, and when the exhaust pipe is blocked, the exhaust pressure is increased, so that it is possible to accurately determine which part to be cleaned or replaced. The presence or absence of such clogging is determined and notified to the user by a signal such as voice, lighting, and display, and the hood controller 27 controls the speed of the exhaust fan motor 211 so as not to overheat. In addition, by comparing the electrical signal for controlling the speed of the exhaust fan motor 211 and the output electrical signal of the wind pressure sensor 24, it is possible to accurately confirm the theoretical air volume and the actual air volume, and more precise air volume control is possible.

In addition, since the pressure sensor 31 checks the flow of the direct flow, which is difficult to determine, and detects a large amount of gas leakage, the shutoff valve 35 is shut off, so that the gas hose connected to the lower end of the flow rate checking shut-off device 40 is cut off. In addition, even when the gas is leaked out in large quantities by detecting it, the shutoff valve 35 may be closed. On the other hand, the intermediate valve 11 has a fuse function, but when the function is lost due to aging, or even if the user arbitrarily lost the fuse function can shut off the shut-off valve 35 can ensure the user's safety have.
