Further, sufficient secondary air is supplied to each flame A by the air from the first branch nozzle 52, and the flame A is pressed by the air from the second branch nozzle 54 so that the top plate is not heated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas stove including a burner in which a plurality of flame holes are annularly arranged toward the center side.

[0002]

[Prior art]

 A circular opening is provided on the top plate of the gas stove, and a burner in which a plurality of flame holes are annularly arranged toward the center side is provided below the top plate so as to be concentric with the opening, and the burner itself is installed. A gas stove which is covered with a top plate to make the design of the upper surface of the gas stove clean and to prevent spills and the like from hitting the burner is known from Japanese Utility Model Publication No. 2-89215.

[0003]

[Problems to be solved by the device]

 In the case of the above annular burner, if a pot is set on the top of the burner for cooking etc., the bottom of the pot hinders the flow of flame and the flow of flame becomes worse than the burner with flame holes on the outer circumference. . Then, the pressure in the space inside the annular burner rises due to the combustion pressure, so that the intake of combustion air from below the burner becomes poor and the combustion state deteriorates.

Further, since the flame holes of the burner are all open toward the center, the flame from each flame hole collides at the center of the burner into one large pillar, but the bottom of the pot is Since the extension of the flame is obstructed, the lower end of the columnar flame extends below the burner, which causes a problem of heating the main body of the gas stove.

In view of the above problems, the present invention provides a gas stove that does not cause deterioration of the combustion state due to insufficient air even if an annular burner is used, and that does not heat the gas stove body or the like. The purpose is to do.

[0006]

In order to achieve the above object, the invention of claim 1 is a gas stove including a burner in which a plurality of flame holes are annularly arranged toward the center side. A blower means for blowing air from below the burner is provided in the inner space surrounded by the flame holes.

A second aspect of the present invention is characterized in that, in the first aspect of the present invention, the air blower unit blows air toward a central portion inside the burner.

Further, in the invention of claim 3, in the invention of claim 2, there is provided branching means for branching a part of the air blown by the air blower toward the upper side of the flame along the upper surface of the burner. Is characterized by.

[0009]

[Action]

 According to the first aspect of the present invention, instead of the air that is not sucked in due to the bad flow of the flame, the air is forcibly sent from below the burner to prevent the combustion inside the burner from becoming worse.

Further, according to the second aspect of the present invention, by blowing air to the central portion of the burner, it is possible to prevent the lower end of the columnar flame formed in the central portion from extending downward, so that the combustion air is insufficient. To prevent the gas stove body from being heated.

At this time, since the flame may be bent upward by the air supply and the top plate may be heated, a part of the air supply is branched to the upper side of the flame along the upper surface of the burner, and the branched air supply is performed. Prevent the flame from rising more than necessary.

【Example】

 With reference to FIG. 1, reference numeral 1 denotes a main body of a gas stove, and an annular burner 2 is arranged below a top plate 11 of the main body 1. The burner 2 is arranged substantially concentric with the circular opening 13 formed in the top plate 11, and a plurality of flame holes 21 are formed toward the center. In this embodiment, the diameter of the opening 13 is slightly smaller than the inner diameter of the burner 2, but it may be the same or slightly larger. In any case, the burner 2 is covered by the top plate 11. It is constructed so that spills and spills will not be directly applied. Further, inside the main body 1, there are provided a blower 3 which is a blower means, and a nozzle 31 which is located below the central portion of the burner 2 and opens upward. Air blown out from the blower 3 passes through a duct 32. The air is blown from below through the nozzle 31 toward the center of the burner 21. A plurality of cutouts 33 are provided on the side surface of the nozzle 31, and boiled spills or the like collected by the funnel-shaped juice receiver 4 are placed on the juice receiver 41 through a drain hole 34 provided directly below the nozzle 31. I tried to collect them. Also, from the notch 33, a part of the air blown from the blower 3 is branched and blown out along the juice receiver 4, and the branched air reaches the lower part of the flame hole 21 and is reversed there and is reversed. Flames from 21 flowed along the underside of A to ensure that each flame was well supplied with air.

According to the above configuration, by compulsorily supplying air from below the burner 2 toward the inside of the burner 2, the combustion pressure of the flame A is overcome and the flame A is acted, and sufficient secondary air is generated. Will be supplied. Further, even if the flame A ejected from the flame hole 21 collides with each other and a columnar flame is formed in the center portion 12, the columnar flame is prevented from extending downward by the air supply from the nozzle 31, and the juice is received. 4 and the main body 1 are not heated.

Next, another embodiment will be described with reference to FIG. In the present embodiment, instead of the nozzle 31, an annular air passage 5 for blowing air from the blower 3 via the duct 32 is provided below the burner 2, and the inner side surface of the air passage 5 is directed obliquely upward. A plurality of nozzles 51 having openings were circumferentially provided substantially evenly. In addition, a first branch nozzle 52 that branches and ejects a part of the blown air along the lower side of the flame A is provided around the upper surface of the blower path 5. Further, an annular branch passage 53 communicating with the duct 32 is provided outside the burner 2, and air is jetted through the gap between the burner 3 and the top plate 11 toward the upper side of the flame A on the inner peripheral surface of the branch passage 53. The second branch nozzle 54 that does this is provided around. According to the above configuration, the air ejected from each nozzle 51 collides from the diagonally lower side in the central portion, so that the columnar flame formed in the central portion 12 of the burner 2 is prevented from extending downward, and The air ejected from the first branch nozzle 52 flows along the lower side of the flame A and supplies sufficient secondary air to each flame A, and the air ejected from the second branch nozzle 54 is directed to the upper side of the flame A. Flow flame A is prevented from rising more than necessary and the top plate is not heated. In each of the above-mentioned embodiments, the soup pan 4 is arranged in contact with the lower side of the burner 2, but it may be arranged such that a gap is provided between them, and the burner 2 in the top plate 11 is covered. Although the parts are formed separately, they may be formed integrally.

[0015]

[Effect of device]

 As is clear from the above description, the present invention can supply sufficient secondary air to the flames from each flame hole even if an annular burner is used, and does not deteriorate the combustion state due to insufficient air. Also, the flames from the respective flame holes collide with each other and the lower end of the columnar flame formed in the center of the burner does not extend downward, and the gas stove body is not heated. At this time, a part of the air supply is branched and the upper surface of the flame from each flame hole is pressed to prevent the top plate from being heated.
