The mixing boss 291 reduces the incomplete combustion in the outer burner 230 by increasing the mixing ratio of the mixed gas, that is, gas and air, supplied to the outer burner 230 through the first mixing tube 241. It plays a role. The mixing boss 291 protrudes downward from the bottom of the outer burner cap 250 corresponding to the upper portion of the first mixing tube 241. The mixing boss 291 may overlap at least a portion of the first mixing tube 241 up and down, preferably, overlapping all of the first mixing tube 241 up and down.

In more detail, an inner space of the outer burner 230 substantially between the upper end of the first mixing tube 241 and the bottom of the mixing boss 291 is adjacent to the outer burner 230. Its volume is reduced relative to other parts of the internal space of. In other words, the inner space of the outer burner 230 corresponding to the upper end of the first mixing tube 241 and the bottom of the mixing boss 291 is the outer burner in the first mixing tube 241. The height in the direction in which the mixed gas is supplied into the inside of 230 is reduced by the thickness of the mixing boss 291. Therefore, the mixed gas flowing while mixing the first mixing tube 241 and supplied into the outer burner 230 is a relatively narrow space (the upper end of the first mixing tube 241 and the mixing boss 291). The mixing ratio of gas and air is increased in the process of flowing from the inner space of the outer burner 230 corresponding to the bottom surface of the outer space) to a relatively large space (another portion of the inner space of the outer burner 230). Therefore, incomplete combustion of the mixed gas in the outer burner 230 is reduced, thereby reducing the amount of carbon monoxide (CO) generated. Referring to [Table 3] below, the difference in the amount of carbon monoxide generated according to whether the mixing boss 291 is provided can be seen more clearly.

That is, as shown in [Table 3], when the mixing boss 291 is provided, the mixing in the top burner 220, in particular the outer burner 230, compared to the prior art that the mixing boss 291 is not provided By reducing the incomplete combustion of the gas, it can be seen that the amount of carbon monoxide generated during the combustion process is significantly reduced.

Hereinafter, with reference to the accompanying drawings a third embodiment of the top burner and the cooking apparatus including the same in the present invention will be described in more detail.

9 is a longitudinal sectional view showing main parts of a third embodiment of the top burner according to the present invention. For the same components as those of the first embodiment of the present invention described above among the components of the present embodiment, reference numerals of FIGS. 1 to 6 are used, and detailed description thereof will be omitted.

Referring to FIG. 9, in the present embodiment, the bottom surface of the outer burner head 240 adjacent to the first mixing tube 241, more specifically, the inner surface of the outer surface of the outer burner head 240 and the first surface thereof. The mixing groove 249 is formed on the bottom surface of the outer burner head 240 corresponding to the outer circumferential surface of the first mixing tube 241. The mixing groove 249 is formed by recessing a portion of the bottom surface of the outer burner head 240 downward. In the present embodiment, the mixing groove 249 is formed to have a fan-shaped longitudinal section having a predetermined center angle as a whole along the edge of the outer burner head 240. In this case, the center angle of the mixing groove 249 may be determined as an angle at which the distance between both ends of the mixing groove 249 is at least equal to or greater than the diameter of the first mixing tube 241.

The mixing groove 249 may be a salt hole 231 or 232 of the outer burner 230 adjacent to the first mixing tube 241 among the salt holes 231 and 232 of the outer burner 230. It serves to prevent the concentration of mixed gas. More specifically, the mixed gas supplied to the inner space of the outer burner 230 through the first mixing tube 241 is discharged through the salt holes 231 and 232 of the outer burner 230 to be combusted. . However, in the case of the outer burner 230, the distance between the first mixing tube 241 and the salt holes 231 and 232 of the outer burner 230 is the salt hole 231 of the outer burner 230 ( It depends on the position of 232). Therefore, a relatively large amount of mixed gas is formed through the salt holes 231 and 232 of the outer burner 230 adjacent to the first mixing tube 241 among the salt holes 231 and 232 of the outer burner 230. It can be discharged or flowed at high speed so that it can be discharged without being accurately mixed. In other words, only the flame formed by the discharge of the mixed gas from the salt holes 231 and 232 of the outer burner 230 adjacent to the first mixing tube 241 is relatively large, and the flames interfere with each other. There is a fear of not burning correctly.

In this embodiment, the flow rate of the mixed gas supplied to the inner space of the outer burner 230 through the first mixing tube 241 flows through the mixing groove 249. More specifically, the mixed gas supplied to the inner space of the outer burner 230 through the first mixing tube 241 flows through the mixing groove 249 to generate a vortex, thereby reducing its flow rate. At the same time, the mixing of gas and air is made more efficient. Therefore, the conventional problem as described above, that is, a phenomenon in which a large amount of mixed gas is discharged at high speed through the salt holes 231 and 232 of the outer burner 230 adjacent to the first mixing tube 241 can be prevented. Can be.

Hereinafter, a fourth embodiment of a top burner and a cooking apparatus including the same according to the present invention will be described in detail with reference to the accompanying drawings.

10 is a perspective view showing the bottom of the fourth embodiment of the top burner according to the present invention. For the same components as those of the first embodiment of the present invention described above among the components of the present embodiment, reference numerals of FIGS. 1 to 6 are used, and detailed description thereof will be omitted.

Referring to FIG. 10, in the present embodiment, a plurality of first shielding members 293 are provided on the bottom of the outer burner head 240, and a second shielding member 295 is disposed on the bottom of the inner burner head 270. It is provided. The first and second shielding members 293 and 295 are formed through the first and second insertion holes 212 and 213 of the top plate 210 formed by cutting a part of the burner installation part 211. The lower portion of the top plate 210, that is, the role of preventing the phenomenon that the soup and the like flows into the inside of the top burner 200.

In the present embodiment, the first and second shielding members 293 and 295 each have an inner circumferential surface thereof spaced apart from the outer circumferential surfaces of the first and second mixing tubes 241 and 271 by a predetermined interval. It extends downward from the bottom of the head 240 or the bottom of the inner burner head 270. In other words, the first and second shield members 293 and 295 respectively surround the first or second mixing tubes 241 and 271, or the bottom of the outer burner head 240 or the inner burner head. 270 is provided on the bottom. The first and second shielding members 293 and 295 are respectively disposed on the upper surface of the burner mounting portion 211 adjacent to the first or second insertion holes 212 and 213 of the top plate 210. Supported. That is, the first and second shielding members 293 and 295 shield the first or second insertion holes 212 and 213 of the top plate 210. To this end, the first and second shielding members 293 and 295 may be formed in a cylindrical shape having a diameter greater than the diameter of the first or second insertion holes 212 and 213 of the top plate 210. have. Therefore, even if the soup of the food overflows, the phenomenon of flowing down into the top burner unit 200 through the first and second insertion holes 212 and 213 of the top plate 210 may be prevented.

Hereinafter, a fifth embodiment of a top burner and a cooking apparatus including the same according to the present invention will be described in detail with reference to the accompanying drawings.

11 is a perspective view showing the bottom of the outer burner head constituting the fifth embodiment of the top burner according to the present invention. For the same components as those of the first embodiment of the present invention described above among the components of the present embodiment, reference numerals of FIGS. 1 to 6 are used, and detailed description thereof will be omitted.

Referring to FIG. 11, in the present embodiment, four first mixing tubes 297 are provided at the outer burner head 240. That is, the mixed gas is supplied to the inner space of the outer burner 230 through the four first mixing tubes 297. The first mixing tube 297 is spaced apart from each other by a predetermined angle, that is, 90 °, on the bottom surface of the outer burner head 240. In this case, the first mixing tube 297 is alternately positioned with the second air guide 248.

Therefore, according to the present exemplary embodiment, a larger amount of mixed gas may be uniformly supplied to the outer burner 230 by the first mixing tube 297. In addition, since a large amount of gas is uniformly supplied to the outer burner 230 as described above, combustion of the mixed gas in the salt holes 231 and 232 of the outer burner 230 may be more efficiently performed. Incomplete combustion of the mixed gas in the top burner 220, in particular, the outer burner 230 may be reduced, thereby reducing the amount of carbon monoxide generated. Referring to Table 4 below, the difference in the amount of carbon monoxide generated according to the number of the first mixing tubes 297 can be seen more clearly.
