Description

A three-dimensional air intake energy-saving gas stove with preheating function

technical field

The utility model belongs to the technical field of heating stoves, in particular to a gas stove.

Background technique

The gas cooker in the existing life is basically composed of a cooker body, an air intake pipe that goes deep into the cooker body, an air distribution port, a gas and air mixing chamber in the cooker body, and a combustion nozzle hole on the upper part of the mixing chamber. The gas is fully combusted, and there is a large gap between the heat conversion rate and the heat energy contained in the fuel. In today's energy shortage situation, it is urgent to improve the problem of excessive energy consumption of the gas cooker used. Although some gas cookers have improved this situation, for example, the utility model patent No. ZL200720093792.7 discloses an energy-saving gas cooker. Preheating duct, one end of the preheating duct is connected to the air supply pipe, and the other end is connected to the air inlet nozzle on the stove body, and the gas is preheated before the gas is burned. Although it can save a certain amount of gas, it is not safe to use. , the preheating conduit is easily burned and leaked, and safety accidents are prone to occur.

Contents of the invention

The purpose of this utility model is to provide a three-dimensional air intake energy-saving gas stove with a preheating function. The gas stove can be used to fully burn the gas to improve the heat conversion efficiency of the gas combustion and achieve the purpose of saving energy and reducing consumption. Safety during use, to overcome the above-mentioned shortcomings that existing gas stoves exist.

The utility model is composed of a stove core and a stove frame. The interior of the stove core is a gas and air mixing chamber. The stove core disk on the upper part of the gas and air mixture chamber is provided with five circles of several combustion nozzles. The stove core disk is a convex ring shape. There are three circles of several direct combustion nozzles on the top surface of the stove core plate, and a circle of several combustion nozzles inclined to the center of the stove core disk is opened on the inner shoulder of the stove core disk. The angle between the inclined combustion nozzles and the horizontal plane is 28° The outer shoulder of the stove core plate is provided with a circle of several direct combustion nozzles, and the stove core has gas and air inlet nozzles; The top surface of the convex ring is lower than the top surface of the stove frame, the gas preheating chamber is arranged in the convex ring, and several side air inlets are opened on the side wall of the convex ring, and the side air inlets are located on the surface of the stove core plate, and the gas preheating chamber is arranged on the side wall of the convex ring. The closed partition between the hot chamber and the side air inlet is not connected to each other. The gas preheating chamber can also be integrally formed on the circumference of the stove frame. The gas inlet end of the gas preheating chamber is connected with the gas supply pipe, and the gas in the gas preheating chamber The gas outlet is connected with the gas and air inlet nozzles, and a valve is installed on the gas supply pipe to control the switch of the gas stove.

The beneficial effects of the utility model are: the gas preheating chamber is arranged in the convex ring of the stove core plate outer circumference of the stove core, so that the flame of the gas can be gathered and burned in a concentrated way, so that the heated pot bottom is heated evenly, and the heat energy can be guaranteed not to scatter. The stove core plate is made into a convex ring shape, so that the flame outlet forms a gradient, which can prevent the inner air port from turning back downward, prevent overflow water from extinguishing, and make the bottom of the heating vessel heat balanced. The flame in the flame hole on the outer shoulder of the stove core plate is evenly injected and burned directly, releasing heat energy to the maximum, achieving high efficiency and energy saving. After the gas is preheated, the gasification is sufficient. Therefore, in the same environment, boil the water with the same initial temperature and the same weight, and weigh the consumption in the natural gas tank. Some gas stoves use 30%-60% less gas, which has a prominent effect on energy saving and consumption reduction. Moreover, because the gas preheating chamber is integrally formed with the stove core or the stove frame, it is resistant to ablation, and it is safer to use without burning leakage. Phenomenon.
