Abstract

This design is used for LPG (liquefied petroleum gas), cabinet heater, and LNG (liquefied natural gas), and it is checked and checked through a separate detect box before various damages caused by gas use. It is a gas leakage alarm and remaining amount, airtightness, CO detection signal device that can prevent safety accidents and release from environmental (air) pollution since it alerts automatically. The intermediate valve 5 and the kitchen utensil 4 of the indoor 10 are installed through the hose 3 having a predetermined length, and the intervener 2 is provided. A pressure sensor and a switch 6 are attached therebetween so that a detection box 7 is installed, and the gas sensor 22 and the CO gas sensor 23 on the input side are buzzers on the output side. 25), the red LED display (26 ~ 28) and the segment LED (50), etc. are respectively installed Gas leak alarms, and the remaining amount, confidential, CO detection signal apparatus.

Technical Field

The present invention relates to a gas leakage alarm and remaining amount, airtight, CO detection signal device used for LPG (liquefied petroleum gas), cabinet heaters, and LNG (liquefied natural gas), and more specifically, Check and check through a separate detection box before the damage of the eggplant, and visually alert, so that gas accidents can be prevented in advance and can be released from environmental (air) pollution. It relates to a detection signal device.

Conventional technology

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 the case of LPG or 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 spring and autumn. It is wet with fog and moisture, freezing in winter with snow and cold, weakening, corroding, damaging and bursting to other surroundings, causing gas loss and safety accidents.

However, in the past, a lot of effort and investment have been made only in the function of checking and detecting between the indoor intermediate valve and the kitchen utensils, and in the case of LNG, the method of checking only the connection part of the indoors as a soap bubble is the only outdoor confidentiality. The method to confirm was unknown.

As described above, according to the present invention, it is composed of outdoor facilities and indoor facilities, which may cause a lot of property and casualties due to safety accidents that can be caused by corrosion, change, and explosion caused by high heat, oil, and other environment generated during cooking. It is equipped with a pressure sensor and switch that can easily detect, check, and check the valve function, airtightness, and leakage in case of disaster. It is possible to provide a gas leakage alarm and remaining amount, airtight, CO detection signal device that can be planned.

In addition, the present invention has been described in detail with respect to the cabinet heater, but can be applied to LPG and LNG within the scope not departing from the gist.

This design makes one product with only the remaining amount checking function and CO sensor function in the cabinet heater, or one product with only gas sensor and CO sensor function, or one product with airtight and leakage function for LNG or LPG. You may use it.
