Technical Field

The invention belongs to the technical field of household gas cookers, and particularly relates to a household gas cooker based on multi-jet tangent circle.

Background

Natural gas is one of the most important fuels for domestic gas cookers in China, and the consumption of the natural gas is rapidly increased along with the improvement of the living standard of residents. As is known, China has become the third world of the world and the consumption of natural gas in China has broken through 2800 billions and cubic meters in 2018. But the current domestic gas range in China also has the phenomena of air hole plug, incomplete combustion and insufficient gas supply.

Aiming at the problems of insufficient gas supply, incomplete combustion and large emission pollution caused by the defects of the structure of the traditional burner, the invention provides a household gas stove with a novel structure which is very necessary.

Disclosure of Invention

The invention aims to solve the technical problems and provides a household gas stove based on multi-jet circle-cutting, which adopts an advanced multi-jet circle-cutting technology and utilizes a multi-jet circle-cutting structure to realize the full mixing of gas and air and reduce pollution.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a domestic gas-cooker based on many efflux circle of contact, includes shell, interior fire lid, outer fire lid, furnace frame, combustion chamber, intake pipe, air duct and ejector, the one end of air duct is connected the intake pipe, other end connection nozzle, the nozzle with the one end connection location of ejector, the ejector the other end with the combustion chamber is linked together, furnace frame, interior, outer fire lid are located shell upper portion sets up corresponding to the combustion chamber, its characterized in that, air duct and ejector are the array, and the several ejector is laid along the even interval of combustion chamber outer fringe.

According to the scheme, the plurality of ejectors are tangent to the outer edge of the combustion chamber in the radial direction.

According to the scheme, the ejector is a Venturi tube and comprises a contraction tube, a throat tube and a diffusion tube, the nozzle is connected with the contraction tube, and an air inlet is formed in the outer side end face of the contraction tube.

According to the scheme, the whole gas stove is made of metal.

The invention has the beneficial effects that: the utility model provides a domestic gas-cooker based on many efflux tangent circles, through lieing in the ejector around the combustion chamber to the premixing of air formation, the last stranded air current forms mixed flow field in the combustion chamber, carries out the effect of mixing once more, and the tangent circle position structure of a plurality of ejectors has more aggravated the vortex when the flow field mixes, makes gas and air obtain abundant mixture, makes the burning more abundant, and the harmful gas of emission still less.

Detailed Description

For a better understanding of the present invention, reference is made to the following description taken in conjunction with the accompanying drawings and examples.

As shown in figure 1, a domestic gas-cooker based on many efflux circle of contact, including shell 1, interior fire lid 2, outer fire lid 3, furnace frame 4, combustion chamber 5, intake pipe 6, air duct 7 and ejector 8, the intake pipe is connected to the one end of air duct, and the nozzle is connected to the other end, and the nozzle is connected the location with the one end of ejector, and the other end and the combustion chamber of ejector are linked together, and furnace frame, interior, outer fire lid are located shell upper portion is corresponding to the combustion chamber setting, and air duct and ejector are the array, and the several ejector is laid along the even interval of combustion chamber outer fringe, and the several ejector is all tangent with the combustion chamber outer fringe in footpath.

The ejector is a Venturi tube and comprises a contraction tube, a throat tube and a diffusion tube, the nozzle is connected with the contraction tube, an air inlet is formed in the end face of the outer side of the contraction tube, fuel gas enters the air guide tube through the air inlet tube and enters the ejector from the air guide tube, and due to the special structure of the ejector, the flow rate of the fuel gas is increased, negative pressure is formed in the ejector, air is sucked from an external coil, and the fuel gas and the air are premixed in the ejector.

The whole gas-cooker is the metal material, and the structure is more firm, and corrosion-resistant ageing, life are longer.

The working principle of the invention is as follows:

the gas flows to the gas guide pipe after passing through the gas inlet pipe and then is divided into three strands, the three strands flow continuously along the gas guide pipe, when the gas enters the ejector through the gas guide pipe, air is sucked into the ejector, the ejector adopts a Venturi tube structure, gas acceleration is realized at the position of the gas and the air, premixing of the air and the gas is completed, when the three ejector pipes are premixed, the gas simultaneously enters the combustion chamber to form a mixed flow field, the gas is fully mixed in the mixed flow field, then the gas flows upwards, and the ignition needle is used for igniting to realize full combustion.

While the present invention has been described with reference to the particular embodiments illustrated in the drawings, which are meant to be illustrative only and not limiting, it will be apparent to those of ordinary skill in the art in light of the teachings of the present invention that numerous modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
