Abstract

The present invention relates to a gas burner used in a house or restaurant. More specifically, an internal gas diffusing path of a burner body is formed into an upward spiral shape, and a burner head with inward and outward transverse outlets is combined with the upper part of the burner body. The burner body makes supplied gas discharged in spiral eddy circulation, and the burner head makes the gas stably and constantly discharged without a jam of the outlets, caused by an overflow of liquid. Therefore, the present invention is excellently universal as the present invention is able to be used for both low pressure and mid-low pressure regardless of pressure of the supplied gas since the gas is able to be discharged with an eddy in an upward spiral direction. The spiral eddy discharge makes a constant amount of gas discharged from all the outlets of the burner head to enable ignition with equal flames. Since the supplied gas in the burner body is discharged in the upward spiral direction even if the gas is mid-low gas, flames in the inward and outward outlets do not collide with each other and are quickly discharged so thermal efficiency is excellent. Since the present invention comprises only the burner body and the burner head, the formation is simple to be suitable for mass production, manufacturing costs are reduced and its lifespan is able to be significantly extended.

Description

[0001] The present invention relates to a gas burner,

The present invention relates to a gas burner for use in a home or a restaurant, and more particularly, to a gas burner comprising a burner body and a burner head, The present invention relates to a gas burner which is capable of improving the ignition efficiency due to the spiral circulation of fuel and achieving complete combustion.

Generally, a gas burner for cooking various foods is installed in a home or a variety of foodservice businesses. In the case of ordinary households, a low-pressure gas is supplied, so that a gas range suitable for low-pressure gas is supplied. Since a stronger flame is required, a sub-low-pressure gas is supplied and a burner suited to the sub-low-pressure gas is used.

At this time, a gas burner of a conventional type used in the home is a burner head in which a lateral discharge port having excellent safety is formed because the discharge pressure of the fuel is relatively weak, and a gas burner for a low- And has a discharge port in the vertical direction to produce a flame.

Here, the low-pressure burner head having the lateral discharge port is relatively safe because it does not block the discharge port or enter the discharge port, even when the soup is overflowing. In the case of the sub-low pressure gas burner, The soup is hardly introduced directly into the discharge port in the vertical direction. Therefore, even though it is less stable than the discharge port in the lateral direction, it is mainly used in restaurants and the like.

The conventional gas burner has different types of burner heads according to the gas pressure supplied through the use purpose and pressure regulator, and the gas burners are not designed to be compatible with each other because they are designed to have their own gas pressures.

A conventional gas burner is composed of a burner body to which a gas supply pipe is connected and a burner head to be placed on the upper side of the burner body. The burner body expands gas supplied from the gas supply pipe widely to the burner head It is a role to supply.

Such a general gas burner has a structure in which, when gas is supplied from a lower side of the burner body, gas is diffused through the inner space of the burner body and discharged through the burner head and the discharge hole of the upper part as in the case of the registered patent No. 10-1229503 It is.

In addition, in the case of Japanese Laid-Open Patent Publication No. 10-2005-0020553, a burner body having an internal space is also provided, and a discharge port of an inclined phase is formed from the burner body to discharge gas and air through the discharge port for the inclined phase and the discharge port for the vertical direction A gas burner has been developed to increase the combustion efficiency of the gas and to prevent the gas from being clogged and to prevent the fire from being extinguished.

In addition, in the case of Registration Practical Utility Model No. 20-0332296, an inner and outer mixed gas spouting parts are formed along the circumferential surface in the upper and outer directions of the burner body, and a flame cover is provided on the upper part of the burner body, A gas burner has been developed in which a flame ejected to a gas ejection portion collides with the flame cover and is guided upward.

However, in the case of a gas burner for low pressure in which the discharge pressure is relatively weak, the conventional gas burner is formed by the combination of the gas discharge port with the lateral discharge port on the outer side and the vertical discharge port on the inner side, The vertical outlet of the inner side is very likely to be extinguished by overflowing the broth, and the outlet of the outer side is also clogged by the overflowing of the broth so that the discharge port is instantaneously extinguished and the unburned gas is discharged to the room will be.

That is, since the discharge pressure of the gas is relatively weak, the low-pressure gas burner applies the discharge port in the lateral direction for wide spread of the flame and applies the discharge port in the vertical direction for the relatively strong flame.

Further, in the case of the sub-low-pressure gas burner, since the gas discharge pressure is relatively strong, it is common to form a discharge port in a vertical direction rather than a discharge port in the lateral direction. In both of these low-pressure gas burners and sub- And it is very weak against the overflow broth since it has the discharge port.

In addition, the gas burner has a donut-shaped gas diffusion path formed therein and is ignited while discharging gas from a plurality of discharge ports connected to the gas diffusion path. The gas is discharged at a relatively strong pressure at the gas supply part while the gas is discharged at a weakened pressure at the discharge port at a position distant from the gas supply part so that the gas burner can not have a uniform flame intensity as a whole I have a closure.

Particularly, in the case of a conventional gas burner having a vertical discharge port, a separate shut-off plate is additionally applied to prevent the vertical discharge port from being clogged. This is not only a cause of cost increase but also an increase in production time and production cost The entire buzzer can not be used in the case where the parts are damaged or lost, which is a very inefficient problem.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems described above and to provide an apparatus and a method for burning a burner, the apparatus including a burner body having an inner gas diffusion path formed in an upward spiral shape and a burner head having inner and outer lateral discharge ports formed on the burner body, The burner body is configured such that the supplied gas is discharged while circulating vortically in a spiral manner and the burner head is configured to continuously and stably discharge the gas to the overflow broth without clogging the discharge port,

As a result, the flame is generated uniformly throughout the gas burner, thereby improving the combustion efficiency. In addition, the discharge port in the lateral direction is capable of maintaining a stable ignition state without being extinguished with respect to the overflow broth, The present invention has an object of providing a low-pressure and quasi-low-pressure gas burner having excellent ignition efficiency and excellent general versatility.

FIG. 4 is a perspective view of the gas burner according to the present invention Fig. 5 is an overall cross-sectional explanatory view of a gas burner according to the present invention. Fig.

As shown in the drawing, the gas burner according to the present invention is composed of a burner body 10 and a burner head 20 as in the prior art. The burner body 10 has a gas connection hole 11 formed at a lower side thereof, In this open form, a gas diffusion part 12 is formed in the form of being in communication with the gas connection port 11. [

In the burner body 10, an air inlet 13 is formed in a vertically communicated state at the center of the inside of the burner body 10, and an air groove 14 is formed inside the tip of the air inlet 13 will be.

At this time, the gas diffusion portion 12 of the burner body 10 is formed in an upward spiral shape on the bottom surface of the gas diffusion portion 12. The gas diffusion portion 12 of the burner body 10, starting from the portion where the gas connection hole 11 is formed, As the screw is formed, the bottom portion is formed in the form of a spiral, so that the gas supplied from the gas connection port 11 will rotate upward in a spiral shape along the bottom surface of the spiral, The gas diffusion portion 12 is circulated and discharged as if the gas spreads evenly throughout the interior thereof.

The burner head 20 is positioned above the burner body 10 so that the inner ring body 22 and the outer ring body 23 are projected downward on the bottom surface of the disc- A gas outlet 21 is formed in a radial direction at the front end of the inner ring body 22. A gas outlet 21 'in the form of a vertical cut is formed in the outer ring body 23 in a radial direction. As shown in FIG.

The inner end of the inner ring body 22 is also protruded from the inner surface of the inner ring body 22 at the upper end of the burner head 20. The outward protruding portion 24 protrudes from the outer surface of the outwardly projecting portion 24, A protruding inward protruding portion 25 protrudes in the form of a step, and a diffusion groove 26 including the above-mentioned gas discharge opening 21 is formed on the inner surface of the inner ring body 22.

The diffusion groove 26 is formed on the inner surface of the inner ring body 22 and is formed on the upper side of the gas discharge port 21 including about half of the circular gas discharge port 21, The gas discharged through the gas discharge port 21 by the discharge port 26 can be discharged in an upward sloping manner.

Accordingly, when a gas having a pressure is supplied through the gas connection port 11 in a state where a low-pressure or sub-low-pressure gas connection pipe is engaged therewith, the supply gas rotates along the spiral shape of the gas diffusion part 12, The gas is uniformly supplied to the entirety of the diffusion part 12 and at the same time is discharged to the opened upper side of the burner body 10 and the pressure is applied to the space between the inner ring body 22 of the burner head 20 and the outer ring body 23 Circulated and vortexed.

The gas is simultaneously discharged to the gas discharge port 21 of the inner ring body 22 and the gas discharge port 21 'of the outer ring body 23 by the gas pressure, and the gas discharge port 21 21 '). ≪ / RTI >

The outer surface of the burner head 20 is also formed of a continuous curved surface from the curved surface of the burner body 10 so that the outer surface of the curved surface is curved Since the flow of air is naturally performed, a smooth ignition state for the gas discharged through the gas discharge openings 21 and 21 'can be continuously performed, so that the combustion efficiency can be increased and the flow of the outside air can be increased along the curved surface The flame will also have an upright natural shape because it will have a rising shape.

Further, the gas can be completely burned by natural inflow and mixing with the outside air irrespective of the low or low pressure of the supplied gas. The flame direction of the inner ring body 22 and the flame of the outer ring body 23 The directions are opposite to each other so that no collision or interference between them occurs at all, and it is very efficient because an even ignition state can be maintained over a large area.

Particularly, since the gas supplied through the gas connection port 11 has a shape that circulates upward along the bottom of the spiral as shown in FIG. 6, the gases supplied from the inside of the burner body 10 collide with each other It is possible to reduce the exhaust noise of the gas to a great extent and to provide an effective ignition state in both the low pressure and the sub-low pressure due to the discharge of the natural gas regardless of the pressure of the supply gas .

The gas burner of the present invention is characterized in that the gas outlets 21 and 21 'are clogged by the broth even if the soup is floated down due to the outward protrusion 24 and the inward protrusion 25 formed in the burner head 20 The inwardly projecting portion 25 protrudes inwardly from the inner surface of the inner ring body 22 as shown in Fig. 7, so that the broth flows inwardly from the inwardly projecting portion 25 even if the broth flows down, The outflow protrusion 24 protruding from the upper end of the outer surface of the outer ring body 23 also does not affect the gas outlet 21 ' It can be used safely because it does not block the gas discharge ports 21 and 21 'and does not extinguish the flame even if the broth flows down.

The burner body 10 according to the present invention has a structure in which the gas is spirally circulated from the internal gas diffusion portion 12 and is rotated relative to the gas diffusion portion 12 at a position adjacent to the gas connection port 11, The gas pressure is relatively high at the farthest position and the gas pressure is relatively weak. Therefore, in order to uniformly ignite the gas in accordance with the change of the gas pressure, the gas outlet 21 and the gas outlet 21 ' So that a flame can be formed.

8, at least three or more sections are formed along the direction of rotation of the gas, and in the portion adjacent to the gas connection port 11 (the strong discharge section), the smallest and narrow gas discharge openings 21, 21 ' And a larger gas outlet 21 or 21 'is formed in the intermediate portion (intermediate discharge portion) which is gradually weakened as compared with the discharge portion of the steel, The gas discharge openings 21 and 21 'in the discharge period of the gas discharge openings 21 and 21' are formed so as to be larger and wider than the discharge openings 21 and 21 ' ') And the width of the inner wall are increased or decreased to uniformly discharge a uniform amount of gas.

In addition, when the difference in size and width of the gas ejection openings 21 and 21 'of the burner head 20 is applied, the burning direction of the burner head 20 relative to the burner body 10 will have a directionality. As shown in Fig. 9, a rotary fixing groove 15 having an upward opening and a groove portion formed in a rotational direction with a predetermined length is formed in an interior groove portion 14 at the tip of the air rising opening 13 of the burner body 10, The burner head 20 is mounted on the burner body 10 by protruding from the outer surface of the inner ring body 22 of the head 20 a protrusion 27 which is inserted into the rotation fixing groove 15, The engaging projections 27 are inserted into the rotation fixing grooves 15 and rotated so that they can be firmly fixed to each other and the gas discharge openings 21 and 21 ' So that it can be positioned at an accurate position.

Accordingly, the gas burner of the present invention discharges the supplied gas upwardly in the form of a spiral circulation inside the burner body, so that the gas can be evenly discharged throughout the burner head, and even when the gas is burned, Efficiency is improved. Even if the soup is overflowed, the gas outlet is not blocked or extinguished due to the soup, and efficient circulation and discharge of the feed gas enables efficient use in both low pressure and sub-low pressure regardless of the pressure of the feed gas Feature.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims.
