Description

Gas stove structure

The present invention relates to a gas range used for cooking food at home or outdoors, and in particular, minimizes the external emission of the heat of combustion, improves the thermal efficiency to the maximum, saves energy, and emits various toxic waste gases generated during combustion. The present invention relates to a gas cooker structure that emits heavy water and minimizes adverse effects on the human body indoors.

In general, it is well known that a gas range used for cooking food at home or outdoors is cooked by burning fire by spreading and mixing LPG and LNG gas with outside air.

In a conventional gas range, a burner connected to a gas inlet pipe is fixedly installed at a central portion thereof with an opening formed at an upper surface thereof, and a support plate is placed at the periphery of the opening so that a constant distance is maintained between the upper surface of the gas range and the bottom of the heating vessel. In the conventional gas range configured as described above, the LPG and LNG gas injected from the burner are mixed with air distributed with caution when the heating vessel is heated to cook food, and the firepower heats the heating vessel. Cooked.

However, in the above gas range, the upper part is always opened, and the base plate is placed so that the upper surface of the opening of the gas range and the bottom of the heating container are spaced at a predetermined interval to smoothly supply air when the gas is ignited. When the burner is ignited and heated with the fire, the flame is heated in direct contact with the bottom and outer circumference of the heating vessel, which releases some of the flame and fire into the atmosphere, which wastes fuel and thermal energy. However, if the burner has a strong thermal power, the flame rises along the outer circumferential surface of the heating vessel to the upper handle portion to melt the handle, and when the heating vessel is moved, the handle portion becomes hot and difficult to grip. The problem is inherent.

On the other hand, when the gas range is used indoors, the base plate and the bottom surface of the heating vessel are burned and heated by a support plate, so that the toxic gas and the heat of combustion generated during the combustion of the gas are released into the room. In case of outdoor use, the top of the gas range and the bottom of the heating vessel are heated in a state where the base plate is kept at regular intervals. When the wind blows, the combustion flame is turned off or the combustion flame is blown by the wind. Since only a part of the heating vessel is heated, the cooking time is long and there is a problem that a lot of fuel is wasted.

The present invention was devised to solve the above-mentioned problems and problems of the prior art, and the main object of the present invention is to intensively heat only the underside of the heating vessel without the sparks burned from the burner of the gas range to the outside. So that food can be cooked within a short time, and the heat of combustion is not discharged to the outside, so that it is possible to not only improve thermal efficiency but also to save energy, and the heat of combustion generated during combustion and toxic waste gas harmful to human body Since the upper part is sealed and mixed with the gas by the air flowing from the lower part, the toxic gas can be released to the outside through the gas discharge pipe without being discharged to the room, thereby minimizing the adverse effect on the human body in the room. Is to provide.
