Description

Radial flame plate and gas burner using the same

The present invention relates to a radial flame plate and a gas burner using the same, and more particularly, to make it possible to easily mix the fuel gas and air, such as LPG or city gas supplied from the outside to complete combustion of the fuel and At the same time it relates to a radial flame plate and a gas burner using the same to increase the ejection pressure to generate a high-efficiency firepower.

In general, a gas burner is used to cook food at home or a restaurant. Especially, a restaurant that cooks a large amount of food is used at home to shorten the cooking time in order to provide food to customers quickly. Gas burners that generate high-efficiency firepower rather than gas ranges are used.

Therefore, the gas burner used in the restaurant is supplied with fuel such as LPG gas or city gas, and when the fuel is ignited, the fuel is burned and the flame is ejected while the fuel is burned to heat the cooking container containing food. This will be cooked.

At this time, the gas burner used in the restaurant is supplied with a high-pressure fuel, unlike the gas range used at home, and the fuel is ejected through a flame outlet provided in the upper portion of the burner, thereby heating the bottom surface of the cooking vessel Food will be cooked.

The conventional gas burner has a burner main body 10 and a burner main body 10 in which a mixing chamber formed in an annular shape is in communication with the inlet pipe 12 into which gas and primary air are introduced, as shown in FIG. 1. It is composed of a flame plate 30, which is detachably seated on the

main flame openings

34 and 36 and the auxiliary flame openings 35 for generating a flame.

In the conventional gas burner, the fuel supplied through the inlet pipe 12 of the burner body 10 is assisted with the

main flame ports

34 and 36 of the flame plate 30 through the mixing chamber of the burner body 10. When the fuel is ejected through the fireball 35 and ignites the fire, the spark is generated, and the cooking vessel is heated by using the flame to cook food.

However, the conventional gas burner uses a large amount of fuel due to the inefficiency in which the thermal power is wasted out of the container compared to the fuel supply amount due to the pressure of the fuel supplied through the inlet pipe 12, but the cooking time is long. In contrast, there was a problem that is not shortened.

In addition, when the gas is combusted, it must be mixed with external air for complete combustion. If the amount of air supplied through the air supply regulator is not properly adjusted, the amount of carbon monoxide generated by incomplete combustion increases, which adversely affects the health of the cook. There was a problem such as going crazy.

In order to solve such a conventional problem, Korean Utility Model Registration No. 20-0309319, "Premixed Gas Burner," has been proposed.

2 to 5b, the radial flame plate and the gas burner 100 using the same according to the present invention are installed on the burner main body 110 and the burner main body 110, and the gas is blown out. It is composed of a flame plate 210 to ignite the spark to form a vortex so that the flame gathers in the center.

Here, the burner body 110 is formed with an inlet pipe 112 through which gas and primary air are introduced from the outside, and the gas and primary air introduced through the inlet pipe 112 are mixed to form a flame plate ( A mixing chamber 114 for ejecting through the 210 is formed, and a coupling member formed with a tubular shape in the center portion and having a passage 118 for guiding secondary air to the combustion unit when combustion of the ejected gas is performed ( 116 is provided.

Therefore, the gas and air are introduced into the mixing chamber 114 through the inlet pipe 112, and the pressure of the gas and air introduced into the mixing chamber 114 is mixed through the inlet pipe 112. It is ejected to the upper through the flame plate 210, by using the flame generated by igniting the fire in this state it is possible to cook food.

Further, the inner one end of the inlet pipe 112 formed in the burner body 110, that is, the inner side of the boundary between the mixing chamber 114 and the inlet pipe 112 protrudes into the mixing chamber 114 to be inclined in one direction. Guide plate 120 is formed.

In this case, the guide plate 120 may be formed only on one side of the inner side of the inlet pipe 112, as shown in the figure, may be formed in a pair to correspond to each other on both sides.

Therefore, the gas and air supplied from the outside through the inlet pipe 112 is moved in one direction in the mixing chamber 114 according to the guide of the guide plate 120 to generate the vortex, in the process of moving in one direction Gas and air are mixed.

In addition, the inner circumferential surface of the mixing chamber 114 of the burner body 110 protrudes outward, and a plurality of guide protrusions 130 are formed in a screw shape.

At this time, the inner circumferential surface of the mixing chamber 114 and the inclined surface 132 in the upper or upper, lower portion of the boundary surface on which the guide protrusion 130 is formed to prevent frictional resistance between the gas moving in one direction from the mixing chamber 114. Is formed.

Therefore, the gas moving in one direction in the mixing chamber 114 is maximized by the centrifugal force and the vortex phenomenon in the moving direction by the guide protrusion 130 formed on the inner circumferential surface of the mixing chamber 114, thereby increasing the mixing ratio of gas and air. Simultaneously with the increase, the movement force is caused by the centrifugal force and the rotational force, thereby generating a pressure higher than the pressure at which gas is introduced through the inlet pipe 112.

In addition, the flame plate 210 has a through hole 214 is formed in the center portion is formed with a coupler 212 is fixed to the coupling member 116 of the burner body 110.

Therefore, the gas supplied to the mixing chamber 114 of the burner body 110 is ejected through the flame plate 210, and ignites the fired gas to ignite the flame to cook food, and at this time, the burner Secondary air is introduced through the passage 118 of the coupling member 116 formed in the main body 110, and the introduced secondary air is supplied to the flame through the through hole 214.

Here, the flame plate 210 has a low central portion and an outer portion, that is, a high edge portion, so that the inclined portion 216 tapered inward from the edge portion is formed, and the inclined portion 216 has a plurality of ejection holes. 218 is formed radially elongated from inside to outside.

At this time, the plurality of blow holes 218 are formed to be inclined in one direction to have a predetermined angle with respect to the central portion of the flame plate (210).

That is, in the mixing chamber 114 of the burner body 110 is formed to be inclined in the same direction as the direction in which the gas moves in one direction.

Therefore, the blowing hole 218 formed in the flame plate 210 is formed to be inclined in the same direction as the moving direction in the mixing chamber 114, so that the centrifugal force issued in the process of moving in the mixing chamber 114 is maintained without losing. Vortex phenomena in the process of being ejected at a high pressure in the compressed state, and is ejected through the inclined portion 216 formed on the flame plate 210 and the ejection hole 218 inclined in one direction to the inclined portion 216 As the gas is generated, the gas is collected at the center part, and when the fire is ignited in this state, the flame is gathered at the center due to the vortex phenomenon, which heats the central part of the bottom surface of the container for cooking food to reduce the cooking time. It can be maximized.

In addition, the outer circumferential surface of the flame plate 210 and the upper end of the inner circumferential surface of the through hole 214 is formed to be connected to the ejection hole 218 is formed inclined portion 219 to be inclined at a predetermined angle.

On the other hand, the inner circumferential surface of the jet hole 218 formed in the flame plate 210 is the same as the gas is moved in one direction in the direction in which the jet hole 218 is inclined, that is, the mixing chamber 114 as shown in FIG. It is formed to be inclined in the direction.

Therefore, by forming the inner peripheral surface of the blowing hole 218 to be inclined in the same direction in which the gas moves, it is possible to eject the gas more easily and generate vortex without losing the rotational force of the gas.

Referring to the operation of the radial flame plate and the gas burner using the same according to the present invention configured as described above are as follows.

In the gas burner 100 according to the present invention, gas and primary air are first supplied to the mixing chamber 114 of the burner body 110 through the inlet pipe 112, and the gas supplied to the mixing chamber 114 is provided. And air is moved in one direction in the mixing chamber 114 of the burner body 110 in accordance with the guide of the guide plate 120, the vortex is generated in the process of moving in the mixing chamber 114.

In addition, the gas that rotates in one direction in the mixing chamber 114 of the burner body 110 is improved by the guide protrusion 130 formed inside the mixing chamber 114.

As such, the gas introduced into the burner body 110 is moved in one direction from the mixing chamber 114 of the burner body 110 to the center by the guide plate 120 to generate centrifugal force. The rotational force in the moving direction is further accelerated by the guide protrusion 130 formed on the inner side of the mixing chamber 114.

Therefore, the gas introduced into the burner body 110 moves in one direction from the mixing chamber 114 and the rotational force in the moving direction is improved by the guide protrusion 130 formed in the mixing chamber 114, thereby reducing the gas and The mixing ratio of the air is improved, the centrifugal force and the rotational force are improved, so that a pressure higher than that of the original gas, that is, a pressure higher than the pressure of the gas flowing through the inlet pipe 112 is generated.

In this way, the gas having a centrifugal force and a high pressure in the mixing chamber 114 of the burner body 110 is ejected through the ejection hole 218 formed in the flame plate 210, and when a fire is ignited in the ejected gas, the flame This causes the cooking vessel for cooking food to be heated.

At this time, when a gas having a centrifugal force and a high pressure generated in the mixing chamber 114 of the burner body 110 is ejected through the ejection hole 218 of the flame plate 210, the gas moves at a constant angle in the same direction in which the gas moves. Since the gas is ejected through the ejection hole 218 formed to be inclined to have a slope, the centrifugal force generated in the mixing chamber 114 is ejected in a maintained state without being lost, thereby maximizing the vortex of the ejected gas.

That is, the blowing hole 218 formed in the flame plate 210 is formed to be inclined in the same direction as the gas moves in the mixing chamber 114, so that the gas centrifugal force and pressure when the gas is ejected through the blowing hole 218 It will be kept ejected.

In addition, the upper end of the flame plate 210 is formed by the inclined portion 216 to face the inner central portion, by forming a blow hole 218 in the inclined portion 216, it is ejected through the blow hole 218 The gas is gathered to the center portion to maximize the thermal efficiency.

As described above, the gas burner 100 according to the present invention forms a vortex while the gas introduced into the mixing chamber 114 of the burner body 110 moves in one direction from the mixing chamber 114, and in addition, the mixing chamber 114 ) Stronger rotational force is generated in the direction of movement by a plurality of guide protrusions 130 formed in a screw shape on the inner wall to improve the mixing ratio of gas and air, and increase the rotational force of the gas to supply pressure to the gas. Higher pressure is generated, and the inclined portion 216 is formed in the flame plate 210, and the ejection hole 218 is formed to be inclined in the direction in which the gas moves in the inclined portion 216. When it is ejected through) vortices are formed and gathered to the central part, and when the fire is ignited by the gas ejected through the ejection hole 218, the flame is gathered to the central part to prevent waste to the outside to have a high thermal efficiency. .

As shown in this figure, an inner circumferential surface of the mixing chamber 114 and an upper or upper and lower boundary surfaces on which the guide protrusion 130 is formed are arc-shaped to prevent frictional resistance between the gas moving in one direction from the mixing chamber 114. The curved surface 134 is formed.

The working relationship for the gas burner according to the present invention configured as described above is made by the same method as in the former, and the description of the working relationship is omitted here.

As shown therein, the inlet pipe 112 formed at one side of the burner body 110 is eccentrically formed at one side of the burner body 110.

Accordingly, the gas supplied to the mixing chamber 114 of the burner body 110 through the inflow pipe 112 formed eccentrically to one side of the burner body 110 naturally moves in one direction in the mixing chamber 114. Will be formed.

In the above, a preferred embodiment of a radial flame plate and a gas burner using the same according to the present invention has been described, but the present invention is not limited thereto, and various claims within the scope of the claims and the detailed description of the invention and the accompanying drawings.
