The plurality of bracket holes 320 may be configured to open toward the burner hole 120. The plurality of bracket holes 320 may be configured to open toward the first burner hole 121.

The plurality of bracket holes 320 may be configured to allow gas discharged through the burner hole 120 to pass therethrough. The plurality of bracket holes 320 may be configured to allow gas discharged through the first burner hole 121 to pass therethrough. The plurality of bracket holes 320 may interfere with radiant heat of the heating unit 210 of the ignition device 200 from being transferred to the burner 100. The plurality of bracket holes 320 may be configured to prevent or reduce radiant heat of the heating unit 210 of the ignition device 200 from being transferred to the burner 100. A detailed description thereof will be provided later.

The cooking apparatus 1 may further include a fixing member 80. The fixing member 80 may be configured to connect the burner 100 and the bracket 300. The fixing member 80 may fix the bracket 300, which accommodates the ignition device 200, to the burner 100. The fixing member 80 may be coupled to each of the burner 100 and the bracket 300.

FIG. 10 is a side view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 11 is a front sectional view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 12 is a perspective view illustrating a bracket according to an embodiment of the present disclosure.

Referring to FIGS. 10 to 12, an example in which the bracket 300 includes a plurality of bracket holes 320a will be described. The same reference numerals are assigned to components that are substantially the same as the aforementioned components, and detailed descriptions thereof may be omitted.

The bracket 300 may include a plurality of bracket holes 320a. The plurality of bracket holes 320a may be arranged to face the first burner hole 121. The plurality of bracket holes 320a may be formed to penetrate the surface 312 of the burner frame 110 facing the first burner hole 121.

The plurality of bracket holes 320a may include a substantially circular shape.

The plurality of bracket holes 320a may be configured to allow gas discharged through the first burner hole 121 to pass therethrough, while preventing or reducing radiant heat of the heating unit 210 from being transferred to the burner 100.

For example, gas G flowing along the gas flow path 110a may be discharged through the burner hole 120. The gas G discharged through the first burner hole 121 may be ignited by passing through the plurality of bracket holes 320a of the bracket 300 and contacting a surface of the heating unit 210. Accordingly, ignition may start at the first burner hole 121. Thereafter, the flame generated at the first burner hole 121 may be transferred to the second burner hole 122. In summary, the gas G discharged through the first burner hole 121 may be ignited by the ignition device 200 after passing through the plurality of bracket holes 320a.

For example, as the bracket 300 has the plurality of bracket holes 320a, the heating unit 210 of the ignition device 200 accommodated in the bracket 300 may not be fully exposed toward the burner 100. As the plurality of bracket holes 320a are formed in the bracket body 310, radiant heat H of the heating unit 210 may not be directly transferred to the burner 100. An area of the burner 100 that directly receives heat from the heating unit 210 may be reduced. The plurality of bracket holes 320a may interfere with radiant heat H of the heating unit 210 from being transferred to the burner 100. The plurality of bracket holes 320a may block radiant heat H of the heating unit 210 from being transferred to the burner 100 or reduce an amount of radiant heat H of the heating unit 210 transferred to the burner 100.

FIG. 13 is a view illustrating the heating device of the cooking apparatus according to an embodiment of the present disclosure. FIG. 14 is a side view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 15 is a front sectional view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 16 is a cross-sectional view taken along line A-A’ of FIG. 13 according to an embodiment of the present disclosure. FIG. 17 is a perspective view illustrating a bracket according to an embodiment of the present disclosure.

Referring to FIGS. 13 to 17, an example in which the bracket 300 includes a plurality of bracket holes 320b will be described. The plurality of bracket holes 320a and the plurality of bracket holes 320b differ only in shape and may perform substantially the same function. Redundant descriptions overlapping with the above-described embodiment(s) may be omitted. The same reference numerals are assigned to components that are substantially the same as the aforementioned components, and detailed descriptions thereof may be omitted.

The bracket 300 may include a plurality of bracket holes 320b. The plurality of bracket holes 320b may be arranged to face the first burner hole 121. The plurality of bracket holes 320b may be formed to penetrate the surface 312 of the burner frame 110 facing the first burner hole 121.

The plurality of bracket holes 320b may include a substantially slit shape. The plurality of bracket holes 320b may have a shape elongated substantially in one direction. For example, the plurality of bracket holes 320b may be elongated substantially along a direction corresponding to an arrangement direction of the first burner hole 121. For example, the plurality of bracket holes 320b may be elongated substantially in a direction intersecting a longitudinal direction of the burner frame 100.

The bracket 300 may include a recess portion 330. The recess portion 330 may be disposed adjacent to the plurality of bracket holes 320b. The recess portion 330 may be configured to communicate with each of the plurality of bracket holes 320b. The recess portion 330 may be open toward each of the plurality of bracket holes 320b.

The recess portion 330 may be configured to guide gas discharged through the burner hole 120. Specifically, the recess portion 330 may guide gas discharged through the first burner hole 121 to pass through the plurality of bracket holes 320b. The recess portion 330 may cause gas discharged through the first burner hole 121 to flow toward the plurality of bracket holes 320b.

The recess portion 330 may be formed to be recessed from the surface 312 of the bracket body 310. The recess portion 330 may include a portion recessed from the surface 312 of the bracket body 310. For example, the recess portion 330 may have a downwardly inclined shape toward the plurality of bracket holes 320b. For example, the recess portion 330 may be formed by a first wall portion 331 inclined downward from the surface 312 of the bracket body 310 and a second wall portion 332 extending substantially parallel to the surface 312 of the bracket body 310 from the first wall portion 331.

For example, a depth d1 of the recess portion 330 recessed from the surface 312 of the bracket body 310 may be greater than a thickness d2 of the bracket body 310. This may enlarge a flow path for guiding gas to the heating unit 210.

Meanwhile, the plurality of bracket holes 320b may be configured to allow gas discharged through the first burner hole 121 to pass therethrough, while preventing or reducing radiant heat of the heating unit 210 from being transferred to the burner 100.

For example, gas G flowing along the gas flow path 110a may be discharged through the burner hole 120. The gas G discharged through the first burner hole 121 may pass through the plurality of bracket holes 320b of the bracket 300. In addition, the gas G discharged through the first burner hole 121 may be guided by the recess portion 330 to pass through the plurality of bracket holes 320b. The recess portion 330 may also guide gas G that is discharged from the first burner hole 121 and diffused to the plurality of bracket holes 320b. The recess portion 330 may increase a flow rate of gas passing through the plurality of bracket holes 320b. The gas G that has passed through the plurality of bracket holes 320b may be ignited by coming into contact with the surface of the heating unit 210. Accordingly, ignition may start at the first burner hole 121. Thereafter, the flame generated at the first burner hole 121 may be transferred to the second burner hole 122. In summary, the gas G discharged through the first burner hole 121 may be ignited by the ignition device 200 after passing through the plurality of bracket holes 320b.

For example, as the bracket 300 has the plurality of bracket holes 320b, the heating unit 210 of the ignition device 200 accommodated in the bracket 300 may not be fully exposed toward the burner 100. As the plurality of bracket holes 320b are formed in the bracket body 310, radiant heat H of the heating unit 210 may not be directly transferred to the burner 100. An area of the burner 100 that directly receives heat from the heating unit 210 may be reduced. The plurality of bracket holes 320b may interfere with radiant heat H of the heating unit 210 from being transferred to the burner 100. The plurality of bracket holes 320b may block radiant heat H of the heating unit 210 from being transferred to the burner 100 or reduce an amount of radiant heat H of the heating unit 210 transferred to the burner 100.

FIG. 18 is a view illustrating the heating device of the cooking apparatus according to an embodiment of the present disclosure. FIG. 19 is a side view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 20 is a front sectional view illustrating part of the heating device according to an embodiment of the present disclosure. FIG. 21 is a perspective view illustrating a bracket according to an embodiment of the present disclosure.

Referring to FIGS. 18 to 21, an example in which the bracket 300 includes a gas guide 340 will be described. Redundant descriptions overlapping with the above-described embodiment(s) may be omitted. The same reference numerals are assigned to components that are substantially the same as the aforementioned components, and detailed descriptions thereof may be omitted.

The bracket 300 may include the gas guide 340. The gas guide 340 may extend from the bracket body 310 toward the burner 100. For example, the gas guide 340 may be formed by bending at least a portion of a surface 312 of the bracket body 310. Alternatively, for example, assuming that the surface 312 of the bracket body 310 is referred to as a first surface 312, and the bracket body 310 includes a second surface 314 connected substantially perpendicular to the first surface 312 and a third surface 315 connected substantially perpendicular to the first surface 312 and facing the second surface 314, the gas guide 340 may extend from the second surface 314 and/or the third surface 315 toward the burner 100.

The gas guide 340 may be configured to guide gas. The gas guide 340 may guide gas discharged through the burner hole 120 to flow toward the heating unit 210. The gas guide 340 may guide gas G discharged through the first burner hole 121 to flow toward the heating unit 210.

The gas guide 340 may include a first guide 341 and a second guide 342 disposed spaced apart from the first guide 341. The first guide 341 and the second guide 342 may be disposed to face each other. The second guide 342 may form a guide flow path 343 together with the first guide 341. The guide flow path 343 may be formed between the first guide 341 and the second guide 342. The guide flow path 343 may be configured to communicate with the burner hole 120. For example, the first guide 341 may extend obliquely from the second surface 314. For example, the second guide 342 may extend obliquely from the third surface 315.

The gas guide 340 may have a tapered shape toward the burner 100. An area of the guide flow path 343 may be configured to decrease toward the burner 100. A spacing distance between the first guide 341 and the second guide 342 may be configured to decrease toward the burner 100. For example, assuming that a spacing distance between ends of the first guide 341 and the second guide 342 is referred to as a first distance S1, and a spacing distance between a portion of the first guide 341 connected to the burner frame 310 and a portion of the second guide 342 connected to the burner frame 310 is referred to as a second distance S2, the first distance S1 may be smaller than the second distance S2.

The gas guide 340 may guide gas G discharged through the first burner hole 121 to the heating unit 210 while increasing a distance between the heating unit 210 and the burner 100.

As a distance between the heating unit 210 and the burner 100 increases, a temperature of the burner 100 may not rise above a predetermined value. The gas guide 340 may secure a spacing between the heating unit 210 and the burner 100 so that the burner 100 is not deformed by radiant heat H of the heating unit 210.

However, as the distance between the heating unit 210 and the burner 100 increases, ignition performance may deteriorate. To prevent this, the gas guide 340 may guide gas to increase a flow rate of gas flowing to the heating unit 210.

Accordingly, the gas guide 340 may allow normal ignition to be achieved while preventing the burner 100 from being deformed by radiant heat H of the heating unit 210.

In general, when the heating device ignites in a hot surface ignition (HSI) manner, a flame generated at the burner may be exposed to heat generated by the ignition device for an extended period of time. A portion of the burner may be deformed by radiant heat of the ignition device. As a portion of the surface of the burner and the burner hole undergo high-temperature oxidation, an area of the burner hole may decrease or the burner hole may become blocked. Accordingly, an amount of gas discharged from the burner hole may decrease, which may result in ignition failure. This may lead to product liability issues.

To address this, the spacing between the ignition device and the burner may be increased; however, it may become difficult for gas discharged from the burner hole to contact the ignition device, resulting in deteriorated ignition performance. Conversely, when the spacing between the ignition device and the burner is decreased, ignition performance may improve, but durability of the burner may be weakened due to deformation of the burner caused by increased temperature. Alternatively, a configuration protecting the ignition device may be removed to prevent the flame generated at the burner from colliding with the ignition device. However, in such a case, the ignition device may be easily damaged during assembly and/or operation. Alternatively, the burner may be made of a heat-resistant material (e.g., stainless steel (STS)). However, the cost of the burner may significantly increase.

According to an embodiment of the present disclosure, the bracket 300 may include the plurality of bracket holes 320 and/or the gas guide 340. The plurality of bracket holes 320 may be configured to allow gas to pass therethrough while interfering with radiant heat of the heating unit 210 from being transferred to the burner 100. The gas guide 340 may be configured to secure a predetermined or greater spacing between the heating unit 210 and the burner 100 while guiding gas to the heating unit 210. By providing the bracket 300 with the plurality of bracket holes 320 and/or the gas guide 340, durability of the burner 100 may be improved while maintaining ignition performance of the burner 100 and the ignition device 200. For example, the burner 100 may not be deformed by radiant heat of the heating unit 210, and an area of the first burner hole 121 may not decrease or the first burner hole 121 may not become blocked.
