It relates to a detection signal device.

[Prior art]

In general, as science and technology and economic growth are radically developed, the concept of consciousness is also considered in various aspects and applied to the living environment.

For example, the kitchen utensil is used to install a gas stove using LPG or LNG in the kitchen to cook and cook food.

As many LPG and LNG kitchen appliances and heating appliances have been developed and distributed, it has made great efforts in improving convenience and environment, and it would not be an exaggeration to say that the family cultural revolution occurred.

Nevertheless, property and life losses due to lack of knowledge in development and use are astronomical figures that are difficult to calculate.

In other words, cabinet heaters, which are frequently used for heating in businesses, offices, and factories, have no safety devices. They are equipped only with a regulator that converts high pressure to low pressure while using a highly explosive gas cylinder in close proximity.

In addition, in the case of LPG and LNG, there is no outdoor inspection and detection function. In the case of LPG, outdoor fuel tanks, regulators, and hoses are exposed to rain and intense sunlight in summer, and in spring and autumn It is wet with fog and moisture and freezes in winter with freezing rain, cold, and other environmental conditions.

However, in the past, a lot of efforts and investments were made only to check and detect between the indoor valves and the kitchen appliances, and in the case of LNG, it was only a method of checking indoor connection parts with soap bubbles. The method to confirm was unknown.

1 is a state diagram of the gas leakage alarm and residual amount, airtightness, CO detection signal apparatus installed in LPG for an embodiment of the present invention, the gas leakage alarm and residual amount, airtight, CO detection signal apparatus of the present invention is LPG (liquefied petroleum Before the various damages caused by the use of the gas stove, which is the kitchen utensil (4), can be checked and checked through the detection box (7) to visually and visually alert, thus preventing safety accidents in advance and the environment (air). Freed from pollution.

First, the liquefied petroleum gas coming out of the LPG fuel tank 1 of the outdoor 9 through the 4 Kgf / cm ² regulator (2) is the intermediate valve (5) of the indoor (10) through a hose (3) of a predetermined length, The sensor and switch 6 and the kitchen utensil 4 are reached in this order.

A pressure sensor and a switch 6 are attached between the intermediate valve 5 and the kitchen appliance 4 so that the detection box 7 is installed through a wire of a predetermined length.

In addition, the fuel tank 1, the regulator 2, and the hose 3 are mostly exposed to the outdoors 9 through the wall 8, and are structurally affected by the surrounding environment, and the rest is indoors 10. Relatively less environmentally affected.

That is, open the tank valve 11 to use the gas in the LPG fuel tank 1 of the outdoor (9), then open the intermediate valve (5) of the indoor (10) to turn on the kitchen utensil (4) to cook It is in condition to be able to do it. When not in use, the tank valve 11 is closed, and the liquefied petroleum gas is filled to the regulator 2, the hose 3, the intermediate valve 5, the pressure sensor and the switch 6, and the kitchen utensil 4. Will be.

At this time, when the liquefied petroleum gas leaks, the gas is discharged to the outside, the pressure is weakened, and the detection box 7 is operated by detecting the lowered pressure by the pressure sensor and the switch 6, so that the buzzer on the output side shown in FIG. The 25 and the red LED display unit 27 operate to visually and visually inform the user, and at the same time, the pressure dropped to the numerical value of the segment LED 50 can be accurately read from the outside.

In addition, the gas sensor 22 and the CO gas sensor 23 on the pressure side in the detection box 7 are respectively installed, and the gas sensor 22 detects the gas which has already leaked out, When the CO concentration is 100 PPM or more, the CO gas sensor 23 operates. Level comparators 32 and 32 to which the threshold level adjusting units 31 and 31 'are connected to the gas sensor 22 and the CO gas sensor 23 on the input side shown in FIG. 2 through temperature compensation units 30 and 30'. ') Are connected to each other, and the pressure sensor and the switch 6 are connected to a level comparator 32 to which a threshold level adjusting unit 31 is connected. The power on delay unit 38 is connected to the level comparators 32, 32 ', and 32, respectively.

The level comparators 32, 32 ', and 32 are connected to a red LED display unit 26-28 while the oan logic circuit 34 is connected, and the red LED display unit 26-28 is connected to a testing unit 35. On the other hand, the output of the oA logic circuit 34 is connected to the red LED display units 26 and 27 through the intermittent oscillator 36. The oA logic circuit 34 outputs OP1 and OP2, respectively, and the output of the intermittent oscillator 36 is connected to the buzzer 25 through the audio frequency oscillator 37, and the other segment LED 50. Supplied to each.

In addition, the voltage for operating the detection box 7 may be AC 110/220 or DC 9V.

3 is a state diagram in which the gas leakage alarm and residual amount, airtightness, CO detection signal device of the present invention are applied to a cabinet heater, and the gas in the gas cylinder 16 is opened through the open coupler 17, the regulator 2, Since the pipe 18 and the combustion plate 20 of constant length are provided, the said regulator 2 makes the high pressure which generate | occur | produces as the liquid in the gas cylinder 16 vaporizes to low pressure. A semiconductor pressure sensor and a pressure switch 6 'are attached between the key coupler 17 and the legator 2 of the gas cylinder 16 to check the remaining amount.
