[0117] For example, the flame generated in the first burner hole (121) and the flame generated in the second burner hole (122) may have different sizes. For example, the intensity of the flame generated in the first burner hole (121) may be weaker than the intensity of the flame generated in the second burner hole (122). For example, the first burner hole (121) and the second burner hole (122) may have different sizes. For example, the size of the first burner hole (121) may be smaller than the size of the second burner hole (122).

[0118] The burner (100) may include an inlet section (130). The inlet section (130) may be provided at one end of the burner frame (110). For example, the inlet section (130) may be provided at one end of the second part (112). Gas may be supplied to the burner (100) through the inlet section (130).

[0121] The ignition device (200) may be an HSI (Hot Surface Ignition) type ignition device. The ignition device (200) may include a heating element (210). The heating element (210) may generate heat. The surface of the heating element (210) may be heated to a high temperature (e.g., approximately 1000 to 1500 degrees). Gas discharged through the burner hole (120) may be ignited by the heat generated in the heating element (210). Gas discharged through the burner hole (120) may be ignited by contact with the surface of the heating element (210). The heating element (210) may be referred to as a heater (210).

[0122] The bracket (300) may be provided to protect the ignition device (200). The ignition device (200) may be mounted inside the bracket (300). The bracket (300) may be provided to enclose at least a portion of the ignition device (200).

A receiving space (311) in which the ignition device (200) is placed may be formed inside the bracket body (310). The bracket body (310) may form the overall appearance of the bracket (300).

[0124] The bracket (300) may include a plurality of bracket holes (320). The plurality of bracket holes (320) may be formed in the bracket body (310). The plurality of bracket holes (320) may be configured to penetrate the bracket body (310).

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

[0125] A plurality of bracket holes (320) may be configured to allow gas discharged through the burner hole (120) to pass through. A plurality of bracket holes (320) may be configured to allow gas discharged through the first burner hole (121) to pass through. A plurality of bracket holes (320) may obstruct the transfer of radiant heat from the heating element (210) of the ignition device (200) to the burner (100). A plurality of bracket holes (320) may be provided to prevent or reduce the transfer of radiant heat from the heating element (210) of the ignition device (200) to the burner (100). A detailed explanation thereof will be provided later.

[0126] The cooking device (1) may further include a fixing member (80). The fixing member (80) may be provided 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).

[0127] The fixing member (80) may be coupled to the bracket (300) by one or more fastening members (F). For example, the fixing member (80) may include a first coupling hole (81), and the bracket (300) may include a second coupling hole (313) corresponding to the first coupling hole (81). With the first coupling hole (81) and the second coupling hole (313) overlapping, the first fastening member (F1) and the second fastening member (F2) may be coupled to each other through the first coupling hole (81) and the second coupling hole (313). Thus, the fixing member (80) and the bracket (300) may be coupled.

[0128] For example, a part of the burner (100) may be provided to be fitted into a fixing member (80). The fixing member (80) may be provided to wrap around a part of the burner frame (110). The fixing member (80) may include a contact projection (82). The contact projection (82) may allow the fixing member (80) and the burner (100) to be stably fixed.

[0130] FIG. 10 is a side view of a part of a heating device according to one embodiment of the present disclosure. FIG. 11 is a front cross-sectional view of a part of a heating device according to one embodiment of the present disclosure. FIG. 12 is a perspective view of a bracket according to one embodiment of the present disclosure.

[0131] Referring to FIGS. 10 to 12, an example in which a bracket (300) includes a plurality of bracket holes (320a) is described. Components substantially identical to the above-described configuration are given the same reference numerals, and detailed descriptions may be omitted.

[0132] 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 by penetrating one side (312) of the burner frame (110) facing the first burner hole (121).

[0133] A plurality of bracket holes (320a) may include a roughly circular shape.

[0134] A plurality of bracket holes (320a) can be configured to allow the discharged gas discharged through the first burner hole (121) to pass through, while preventing or reducing the transfer of radiant heat from the heating element (210) to the burner (100).

[0135] For example, gas (G) flowing along the gas path (110a) can be discharged through the burner hole (120). Gas (G) discharged through the first burner hole (121) can pass through a plurality of bracket holes (320a) of the bracket (300) and be ignited upon contact with the surface of the heating element (210). Thus, ignition can begin in the first burner hole (121). Subsequently, the fire generated in the first burner hole (121) can be transferred to the second burner hole (122). In summary, gas (G) discharged through the first burner hole (121) can pass through a plurality of bracket holes (320a) and be ignited by the ignition device (200).

[0136] For example, by having a plurality of bracket holes (320a) in the bracket (300), the heating element (210) of the ignition device (200) housed in the bracket (300) may not be completely exposed toward the burner (100). By forming a plurality of bracket holes (320a) in the bracket body (310), the radiant heat (H) of the heating element (210) may not be directly transferred to the burner (100). The area of ​​the burner (100) that receives heat directly from the heating element (210) may be reduced. The plurality of bracket holes (320a) may obstruct the transfer of radiant heat (H) of the heating element (210) to the burner (100). A plurality of bracket holes (320a) can block the radiant heat (H) of the heating element (210) from being transferred to the burner (100) or reduce the amount of radiant heat (H) of the heating element (210) being transferred to the burner (100).

[0137] FIG. 13 illustrates a heating device of a cooking appliance according to one embodiment of the present disclosure. FIG. 14 is a side view of a part of a heating device according to one embodiment of the present disclosure. FIG. 15 is a front cross-sectional view of a part of a heating device according to one embodiment of the present disclosure. FIG. 16 is a cross-sectional view along the line A-A' indicated in FIG. 13. FIG. 17 is a perspective view of a bracket according to one embodiment of the present disclosure.

[0138] Referring to FIGS. 13 to 17, an example in which a bracket (300) includes a plurality of bracket holes (320b) is described. The plurality of bracket holes (320a) and the plurality of bracket holes (320b) differ only in shape and can perform substantially the same function. Content that overlaps with the description of the aforementioned embodiment(s) may be omitted. The same reference numerals are assigned to configurations that are substantially identical to the aforementioned configurations, and detailed descriptions may be omitted.

[0139] 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 by penetrating one side (312) of the burner frame (110) facing the first burner hole (121).

[0140] A plurality of bracket holes (320b) may include a slit shape. A plurality of bracket holes (320b) may have a shape that is elongated in one direction. For example, a plurality of bracket holes (320b) may be extended to correspond approximately to the direction in which the first burner holes (121) are arranged. For example, a plurality of bracket holes (320b) may be extended in a direction that intersects approximately with the longitudinal direction of the burner frame (100).

[0141] The bracket (300) may include a recess (330). The recess (330) may be positioned adjacent to a plurality of bracket holes (320b). The recess (330) may be provided to communicate with each of the plurality of bracket holes (320b). The recess (330) may be open toward each of the plurality of bracket holes (320b).

[0142] The recess section (330) may be provided to guide the gas discharged through the burner hole (120). Specifically, the recess section (330) may guide the gas discharged through the first burner hole (121) to pass through a plurality of bracket holes (320b). The recess section (330) may cause the gas discharged through the first burner hole (121) to flow toward the plurality of bracket holes (320b).

[0143] The recess portion (330) may be formed by being recessed from one side (312) of the bracket body (310). The recess portion (330) may include a portion recessed from one side (312) of the bracket body (310). For example, the recess portion (330) may have a shape that slopes downward toward a plurality of bracket holes (320b). For example, the recess portion (330) may be formed by a first wall portion (331) that slopes downward from one side (312) of the bracket body (310), and a second wall portion (332) that extends from the first wall portion (312) approximately parallel to one side (312) of the bracket body (310).

[0144] For example, the depth (d1) of the recess (330) being recessed from one side (312) of the bracket body (310) may be greater than the thickness (d2) of the bracket body (310). This allows the flow path for guiding gas to the heating element (210) to be expanded.

[0145] Meanwhile, a plurality of bracket holes (320b) may be configured to allow the discharged gas discharged through the first burner hole (121) to pass through, while preventing or reducing the transfer of radiant heat from the heating element (210) to the burner (100).

[0146] For example, gas (G) flowing along the gas path (110a) can be discharged through the burner hole (120). Gas (G) discharged through the first burner hole (121) can pass through a plurality of bracket holes (320b) of the bracket (300). Additionally, gas (G) discharged through the first burner hole (121) can be guided by the recess section (330) to pass through the plurality of bracket holes (320b). The recess section (330) can also guide the gas (G) discharged and diffused from the first burner hole (121) to the plurality of bracket holes (320b). The recess section (330) can increase the flow rate of gas passing through the plurality of bracket holes (320b). Gas (G) passing through the plurality of bracket holes (320b) can be ignited upon contact with the surface of the heating element (210). Thus, ignition can be started in the first burner hole (121). Subsequently, the fire generated in the first burner hole (121) can be transferred to the second burner hole (122). In summary, the gas (G) discharged through the first burner hole (121) passes through a plurality of bracket holes (320b) and can be ignited by the ignition device (200).

[0147] For example, by having a plurality of bracket holes (320b) in the bracket (300), the heating element (210) of the ignition device (200) housed in the bracket (300) may not be completely exposed toward the burner (100). By forming a plurality of bracket holes (320b) in the bracket body (310), the radiant heat (H) of the heating element (210) may not be directly transferred to the burner (100). The area of ​​the burner (100) that receives heat directly from the heating element (210) may be reduced. The plurality of bracket holes (320b) may obstruct the transfer of radiant heat (H) of the heating element (210) to the burner (100). A plurality of bracket holes (320b) can block the radiant heat (H) of the heating element (210) from being transferred to the burner (100) or reduce the amount of radiant heat (H) of the heating element (210) being transferred to the burner (100).

[0148] FIG. 18 illustrates a heating device of a cooking appliance according to one embodiment of the present disclosure. FIG. 19 is a side view of a part of a heating device according to one embodiment of the present disclosure. FIG. 20 is a front cross-sectional view of a part of a heating device according to one embodiment of the present disclosure. FIG. 21 is a perspective view of a bracket according to one embodiment of the present disclosure.

[0149] Referring to FIGS. 18 through 21, an example in which the bracket (300) includes a gas guide (340) is described. Content that overlaps with the description of the aforementioned embodiment(s) may be omitted. The same reference numerals are assigned to configurations that are substantially identical to the aforementioned configurations, and detailed descriptions may be omitted.

[0150] The bracket (300) may include a 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 one side (312) of the bracket body (310). Alternatively, for example, assuming that one side (312) of the bracket body (310) is referred to as the first side (312), and that the bracket body (310) includes a second side (314) connected approximately perpendicularly to the first side (312) and a third side (315) connected approximately perpendicularly to the first side (312) and facing the second side (314), the gas guide (340) may extend from the second side (314) and / or the third side (315) toward the burner (100).

[0151] The gas guide (340) can be configured to guide the gas. It can guide the gas discharged through the burner hole (120) to flow toward the heating element (210). The gas guide (340) can guide the gas (G) discharged through the first burner hole (121) to flow toward the heating element (210).

[0152] The gas guide (340) may include a first guide (341) and a second guide (342) spaced apart from the first guide (341). The first guide (341) and the second guide (342) may be arranged to face each other. The second guide (342) may form a guide channel (343) together with the first guide (341). A guide channel (343) may be formed between the first guide (341) and the second guide (342). The guide channel (343) may be arranged 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).

[0153] The gas guide (340) may have a shape that tapers toward the burner (100). The area of ​​the guide channel (343) may be arranged to decrease toward the burner (100). The distance between the first guide (341) and the second guide (342) may be arranged to decrease toward the burner (100). For example, when the distance between the end of the first guide (341) and the end of the second guide (342) is called the first distance (S1), and the distance between the part of the first guide (341) connected to the burner frame (310) and the part of the second guide (342) connected to the burner frame (310) is called the second distance (S2), the first distance (S1) may be smaller than the second distance (S2).

[0154] The gas guide (340) can guide the gas (G) discharged through the first burner hole (121) to the heating part (210) while increasing the distance between the heating part (210) and the burner (100).

[0155] As the distance between the heating element (210) and the burner (100) increases, the temperature of the burner (100) may not rise above a predetermined value. The gas guide (340) can secure a gap between the heating element (210) and the burner (100) so that the burner (100) is not deformed by the radiant heat (H) of the heating element (210).

[0156] However, as the distance between the heating element (210) and the burner (100) increases, the ignition performance may decrease. To prevent this, the gas guide (340) can guide the gas to increase the flow rate of the gas flowing to the heating element (210).

[0157] Thus, the gas guide (340) can ensure normal ignition without the burner (100) being deformed by the radiant heat (H) of the heating element (210).

[0158] Generally, when a heating device uses the Hot Surface Ignition (HSI) method, the flame generated by the burner may be exposed to heat from the ignition device for an extended period. Parts of the burner may be deformed by the radiant heat from the ignition device. As parts of the burner surface and the burner holes undergo high-temperature oxidation, the surface area of ​​the burner holes may shrink or become clogged. Consequently, the amount of gas emitted from the burner holes is reduced, which can lead to ignition failures. This can result in issues under product liability laws.

[0159] To address this, the gap between the ignition device and the burner can be widened; however, this may degrade ignition performance as it becomes difficult for gases emitted from the burner hole to come into contact with the ignition device. Conversely, narrowing the gap may improve ignition performance, but it may weaken the burner's durability, such as causing deformation due to temperature rise. Alternatively, the protective structure for the ignition device can be removed to prevent the flame generated by the burner from colliding with the ignition device. However, in this case, the ignition device may be easily damaged during assembly and / or operation. Alternatively, the burner can be manufactured from a material with excellent heat resistance (e.g., stainless steel). However, this may significantly increase the cost of the burner.

[0160] According to one embodiment of the present disclosure, the bracket (300) may include a plurality of bracket holes (320) and / or gas guides (340). The plurality of bracket holes (320) may be configured to allow gas to pass through while preventing radiant heat from the heating element (210) from being transferred to the burner (100). The gas guides (340) may be configured to guide the gas to the heating element (210) while ensuring a distance between the heating element (210) and the burner (100) of at least a predetermined interval. By providing the plurality of bracket holes (320) and / or gas guides (340), the bracket (300) can improve the durability of the burner (100) while maintaining the ignition performance of the burner (100) and the ignition device (200). For example, the burner (100) may not be deformed by the radiant heat of the heating element (210), and the area of ​​the first burner hole (121) may not be reduced or the first burner hole (121) may not be blocked.
