[0067] FIG. 5 is a side cross-sectional view of a cooking apparatus according to an embodiment. FIG. 6 is an enlarged view of an area A of FIG. 5.

[0068] A flow of air of the air conditioner 1 according to an embodiment will be described with reference to FIGS. 5 and 6.

[0069] Referring to FIGS. 5 and 6, the cooking apparatus 1 may include an air guide 100 that guides air discharged in a front direction of the machine room 22 by the fan 60 downward from the machine room 22. The air guide 100 may guide air discharged in the front direction of the machine room 22 downward from the cooktop case 23.

[0070] The cooktop case 23 may include an outlet 24 formed in a front side of the cooktop case 23 to discharge internal air of the machine room 22 to outside of the machine room 22. The outlet 24 may be formed by penetrating the front side of the cooktop case 23. The outlet 24 may include a plurality of holes and/or a hole extending in one direction.

[0071] The air guide 100 may guide air discharged in the front direction of the cooktop case 23 through the outlet 24 downward from the cooktop case 23. The air guide 100 may guide air discharged in the front direction of the machine room 22 downward from the machine room 22 and then guide the air toward a rear direction of the machine room 22. In other words, the air guide 100 may change a moving direction of air moving in a first direction by the fan 60 to a second direction that is opposite to the first direction. According to an embodiment, the first direction may be the front direction, and the second direction may be the rear direction.

[0072] The cooking apparatus 1 according to an embodiment may include the air guide 100 coupled to the front side of the cooktop case 23, thereby causing air that has cooled inside of the cooktop 20 to pass between the cooktop 20 and the main body 10 without being directly discharged to the outside of the cooktop 20. In other words, air moving in the front direction 104 by the fan 60 may be discharged to the outside of the machine room 22 through the outlet 24 formed in the front side of the cooktop case 23, and the air discharged to the outside of the machine room 22 may move downward by the air guide 100. At this time, a moving direction of the air may be reversed. The air moved downward by the air guide 100 may move toward the rear direction below the cooktop case 23.

[0073] Air moving in the rear direction 105 below the cooktop case 23 may be discharged to the outside of the cooking apparatus 1 together with stagnant heat in a space 10a between the cooktop 20 and the main body 10. The space 10a between the main body 10 and the cooktop 20 may be below the machine room 22, below the cooktop case 23, or above the main body 10.

[0074] Because stagnant heat in the space 10a between the cooktop 20 and the main body 10 is discharged to the outside of the cooking apparatus 1, the space 10a between the main body 10 and the cooktop 20 may be cooled. While internal temperature of the cooking room 11 rises, heat may be transferred upward from the main body 10. Therefore, heat may be transferred to the space 10a between the main body 10 and the cooktop 20, and the heat may be transferred to the machine room 22 to damage electronic components inside the machine room 22. As described above, air guided to the space 10a between the main body 10 and the cooktop 20 by the air guide 100 may move to a rear portion of the cooking apparatus 1 together with stagnant heat in the space 10a and then, be discharged to the outside of the cooking apparatus 1 along the discharge flow path 34 formed inside the protruding portion 30. Due to the air guide 100, stagnant heat in the space 10a between the main body 10 and the cooktop 20 may be discharged to the outside of the cooking apparatus 1, which prevents the space 10a between the main body 10 and the cooktop 20 from being overheated while preventing the electronic components inside the machine room 22 from being damaged by heat.

[0075] Referring to FIG. 6, the air guide 100 may include a cover guide 101 that covers an area spaced in the front direction from the front side of the cooktop case 23 to guide air discharged in the front direction of the machine room 22 through the outlet 24 of the cooktop case 23 downward from the machine room 22. The cover guide 101 may be inclined downward toward the rear direction to guide air moving in the front direction downward.

[0076] The air guide 100 may include an extension guide 102 that is spaced downward from the bottom of the cooktop case 23 and connected to the cover guide 101 to guide air moved downward from the machine room 22 by the cover guide 101 in the rear direction. The extension guide 102 may extend horizontally along a front-rear direction.

[0077] As shown in FIG. 6, the extension guide 102 may extend to substantially a center of the bottom of the cooktop case 23. Alternatively, the extension guide 102 may extend to a rear end of the bottom of the cooktop case 23 or adjacent to the rear end of the bottom of the cooktop case 23.

[0078] The air guide 100 may further include an upper cover 103 that prevents air discharged in the front direction of the machine room 22 from moving upward along the cover guide 101 and being discharged upward from the machine room 22. The upper cover 103 may be connected to the cover guide 101 and the front side of the cooktop case 23. The upper cover 103 may extend substantially vertically, although not limited thereto. However, the upper cover 103 may be inclined to connect an upper end of the cover guide 101 to a portion of the front side of the cooktop case 23.

[0079] Referring to FIGS. 5 and 6, the cooking apparatus 1 may include a cover plate 110 positioned below the cooktop case 23. The cover plate 110 may form an upper side of the outer case 13, although not limited thereto. An upper panel forming the upper side of the outer case 13 may be provided separately and the cover plate 110 may be positioned on the upper panel.

[0080] The cover plate 110 may prevent the insulation surrounding the inner case 11 from being exposed below the cooktop case 23. The cover plate 110 may cover the insulation positioned on an upper side of the inner case 11 forming the cooking room 11. Because the cover plate 110 covers an upper side of the insulation, an amount of heat transferred upward from the insulation may be reduced. The cover plate 110 may be positioned below the cooktop case 23 or above the main body 10 to reduce an amount of heat transferred to the space 10a between the cooktop 20 and the main body 10.

[0081] Also, unlike the drawings, the outer case 11 may include an upper panel accommodating the insulation therein, and the cover plate 110 may be provided on the upper panel of the outer case 11. In this case, the cover plate 110 may be spaced a preset distance upward from an upper side of the upper panel. Through this arrangement, an air gap may be formed between the upper panel and the cover plate 110, and the air gap may reduce transfer of heat.

[0082] FIG. 7 shows some components of a cooking apparatus according to an embodiment. FIG. 8 shows some components of the cooking apparatus shown in FIG. 7 and an air guide separated from the components.

[0083] Referring to FIGS. 7 and 8, in the cooking apparatus 1 according to an embodiment, the air guide 100 may be coupled to the front side of the cooktop case 23. As described above, because the first fan 61 and the second fan 62 are arranged in the rear space of the machine room 22 to form a flow of air toward the front direction, the air guide 100 may be coupled to the front side of the cooktop case 23 and positioned in front of the machine room 22.

[0084] The cooktop case 23 may include the outlet 24 formed in the front side of the cooktop case 23. The outlet 24 may include, but is not limited to, a pair of first outlets 24a which are holes respectively formed in the front direction of the first fan 61 and the second fan 62 and having relatively great sizes, and a plurality of second outlets 24b which are a plurality of holes formed between the pair of first outlets 24a and having relatively small sizes. However, the outlet 24 may include only a plurality of holes or a single hole extending in a left-right direction. Also, the outlet 24 may include a plurality of holes having a different shape from that shown in FIGS. 7 and 8.

FIG. 10 shows some components of the cooking apparatus shown in FIG. 9 and an air guide separated from the components. FIG. 11 is an enlarged view showing a part of a side cross section of a cooking apparatus according to an embodiment.

[0086] Referring to FIGS. 9 and 10, the cooking apparatus 1 may include a cooktop case 123 forming the machine room 22, and an outlet 124 formed in a rear side of the cooktop case 123. Also, the cooking apparatus 1 may include a fan 160 positioned in a front space of the machine room 22, and a duct 170 that guides air to the fan 160. The fan 160 may be positioned in the front space of the machine room 22 to form a flow of air toward the rear direction. The fan 160 may include a first fan 161 positioned to one side of the machine room 22 and a second fan 162 positioned to another side of the machine room 22. The duct 170 may include a first duct 171 positioned to one side of the main body 10 to guide air below the main body 10 to the first fan 161, and a second duct 172 positioned to another side of the main body 10 to guide air below the main body 10 to the second fan 162.

[0087] According to an embodiment, the cooking apparatus 1 may include an air guide 200 that guides air discharged in the rear direction of the machine room 22 by the fan 160 downward from the machine room 22. The air guide 200 may guide air discharged in the rear direction of the machine room 22 downward from the cooktop case 123.

[0088] The cooktop case 123 may include the outlet 124 formed in the rear side of the cooktop case 123 to discharge internal air of the machine room 22 to the outside of the machine room 22. The outlet 124 may be formed by penetrating the rear side of the cooktop case 123. The outlet 124 may include a plurality of holes and/or a hole extending in one direction.

[0089] The air guide 200 may guide air discharged in the rear direction of the cooktop case 123 through the outlet 124 downward from the cooktop case 123. The air guide 200 may guide air discharged in the rear direction of the machine room 22 downward from the machine room 22 and then guide the air toward the front direction of the machine room 22. In other words, the air guide 200 may change a moving direction of air moving in a first direction by the fan 160 to a second direction that is opposite to the first direction. According to an embodiment, the first direction may be the rear direction, and the second direction may be the front direction.

[0090] The cooking apparatus 1 according to the disclosure may include the air guide 200 coupled to the rear side of the cooktop case 123, thereby causing air that has cooled the inside of the cooktop 20 to pass between the cooktop 20 and the main body 10 without being directly discharged to the outside of the cooktop 20. In other words, air 204 moving in the rear direction by the fan 160 may be discharged to the outside of the machine room 22 through the outlet 124 formed in the rear side of the cooktop case 123, and the air discharged to the outside of the machine room 22 may move downward by the air guide 200. At this time, a moving direction of the air may be reversed. The air moved downward by the air guide 100 may move toward the front direction below the cooktop case 123.

[0091] Air 205 moved in the front direction below the cooktop case 123 may be discharged to the outside of the cooking apparatus 1 together with stagnant heat in the space 10a between the cooktop 20 and the main body 10. The space 10a between the main body 10 and the cooktop 20 may be below the machine room 22, below the cooktop case 123, or above the main body 10.

[0092] Because stagnant heat in the space 10a between the main body 10 and the cooktop 20 is discharged to the outside of the cooking apparatus 1, the space 10a between the main body 10 and the cooktop 20 may be cooled. While internal temperature of the cooking room 11 rises, heat may be transferred upward from the main body 10. Therefore, heat may be transferred to the space 10a between the main body 10 and the cooktop 20, and the heat may be transferred to the machine room 22 to damage the electronic components inside the machine room 22. As described above, air guided to the space 10a between the main body 10 and the cooktop 20 by the air guide 200 may move to the front portion of the cooking apparatus 1 together with stagnant heat in the space 10a and then, be discharged to the outside of the cooking apparatus 1. Therefore, the space 10a between the main body 10 and the cooktop 20 may be prevented from being overheated, and also, the electronic components inside the machine room 22 may be prevented from being damaged by heat.

[0093] Referring to FIGS. 10 and 11, the air guide 200 may include a cover guide 201 that covers an area spaced downward from the rear side of the cooktop case 23 to guide air discharged in the rear direction of the machine room 22 through the outlet 124 of the cooktop case 123 downward from the machine room 22. The cover guide 201 may be inclined downward toward the front direction to guide air moving in the rear direction downward.

[0094] The air guide 200 may include an extension guide 202 that is spaced downward from the bottom of the cooktop case 123 and connected to the cover guide 201 to guide air moved downward from the machine room 22 by the cover guide 201 in the front direction. The extension guide 202 may extend horizontally along the front-rear direction.

[0095] As shown in FIG. 11, the extension guide 202 may extend to substantially a center of the bottom of the cooktop case 123. Alternatively, the extension guide 102 may extend to a front end of the bottom of the cooktop case 123 or adjacent to the front end of the bottom of the cooktop case 123.

[0096] The air guide 200 may further include an upper cover 203 that prevents air discharged in the front direction from the machine room 22 from moving upward along the cover guide 201 and being discharged upward from the machine room 22. The upper cover 203 may be connected to the cover guide 201 and the rear side of the cooktop case 123. The upper cover 203 may extend substantially vertically. However, the present disclosure is not limited thereto, and the upper cover 203 may be inclined to connect an upper end of the cover guide 201 to a portion of the front side of the cooktop case 123.

[0097] Referring to FIGS. 9 and 10, in the cooking apparatus 1 according to an embodiment, the air guide 200 may be coupled to the rear side of the cooktop case 123.
