[0125] Glasses 170 and 180 including a plurality of first glasses 170 and second glasses 180 are disposed at a lower portion of the camera 140, and the two first glasses 170 are fixed to glass holders 190 to be disposed at upper and lower surfaces of the top 18, and the plurality of second glasses 180 are fixed to a glass support 150 disposed near a lower portion of the camera 140.

[0126] The drawings illustrate the glasses 170 and 180 including two first glasses 170 and two second glasses 180, but the number of glasses 170 and 180 is not limited thereto. Each of the first glass 170 and the second glass 180 may be provided as one or at least three glasses, and the glasses 170 and 180 may be provided as a single glass without being separated into the first glass 170 and the second glass 180.

[0127] When the glass 170 and 180 is provided as one, the glass 170 and 180 is preferably provided to have a thickness of 4 mm or more.

[0128] When the glasses 170 and 180 are separated into the first glass 170 and the second glass 180 , the total thickness of the first glass 170 and the second glass 180 is preferably about 4 mm or more.

[0129] When the thickness of the glass 170 and 180 is about 4 mm or more, the heat reflecting coating layer 175 is provided on one surface of the glass 170 and 180, as shown in FIG. Figure 6 As shown, a heat reflective coating 175 may be provided on both sides of the glass 170 and 180, as shown. Figure 7 shown.

[0130] When the heat reflective coating layer 175 is provided on one surface of the glasses 170 and 180 , the surface on which the heat reflective coating layer 175 is provided is preferably provided to face the cooking chamber 20 .

[0131] In addition, the glasses 170 and 180 may be formed of heat-resistant or borosilicate tempered glass to prevent damage caused by heat. When a plurality of glasses 170 and 180 are provided, only the glass 170 closest to the cooking chamber 20 may be formed of tempered glass or borosilicate glass.

[0132] The glass holder 150 includes a glass fixing member 151, a sealing member 152 having an insertion hole 153, and a second coupling portion 157 coupled to the bottom surface 57 of the electric component cavity 50. The plurality of second glasses 180 are fixed to the glass fixing member 151. The end portion of the body tube 143 of the camera 140 on which the lens 145 is provided is inserted into the insertion hole 153.

[0133] The space in which the end of the body tube 143 of the camera 140 in which the lens 145 is disposed is inserted is sealed by the second glass 180 disposed on top of a plurality of second glasses 180 and a seal 152 to prevent foreign materials such as dust from entering the lens 145 .

[0134] Because only the end of the body tube 143 of the camera 140 where the lens 145 is set is inserted into the insertion hole 153, when the user views the camera 140 in the cooking chamber 20, the remaining portion of the camera 140 except the lens 145 is not visible, and exposure of an unnecessary portion is prevented.

[0135] Glass support 150, such as Figure 9 As shown, it can be configured to include a glass fixing member 151, an opening 154 opened to accommodate the end of the body tube 143, and a gasket 155, a plurality of second glasses 180 are fixed to the glass fixing member 151, and the gasket 155 is detachably connected to the opening 154 and has an insertion hole 156, and the end of the body tube 143 is inserted into the insertion hole 156.

[0136] exist Figure 9 In the case of the glass holder 150 shown, the space in which the end of the body tube 143 of the camera 140 in which the lens 145 is set is inserted is sealed by a gasket 155 and a second glass 180 set at the top of a plurality of second glasses 180 to prevent foreign materials such as dust from entering the lens 145.

[0137] The third opening 59 is provided at the bottom surface 57 of the electric component cavity 50 at a position corresponding to the second opening 54 provided in the exhaust duct 53 , and a glass holder coupling hole 59 a to which the glass holder 150 is coupled is provided around the third opening 59 .

[0138] The glass holder 150 is coupled to the bottom surface 57 of the electric component cavity 50 by a fastener B, which is inserted into the glass holder coupling hole 59 a and the second coupling portion 157 , and the lens 145 provided on the glass holder 150 captures the interior of the cooking chamber 20 through the third opening 59 provided in the bottom surface 57 of the electric component cavity 50 and the second glass 180 fixed to the glass holder 150 .

[0139] A first opening 18 b provided on the top 18 of the cooking chamber 20 is positioned to correspond to the second opening 54 provided on the exhaust duct 53 and the third opening 59 provided on the bottom surface 57 of the electric component cavity 50, and a glass holder coupling hole 18 c is provided around the first opening 18 b. The glass holder coupling hole 18 c is coupled to a glass holder 190 on which the first glass 170 is mounted.

[0140] The glass holder 190 includes a fourth coupling portion 191 disposed to correspond to the glass holder coupling hole 18c and is coupled to the top 18 of the cooking chamber 20 by a fastener B inserted into the glass holder coupling hole 18c and the fourth coupling portion 191.

[0141] Because the glass holder 190 is attachable to or detachable from the top 18 of the cooking chamber 20, when foreign material is disposed on the first glass 170 above the cooking chamber 20, the glass holder 190 can be separated from the top 18 of the cooking chamber 20, and then the foreign material on the first glass 170 can be removed.

[0142] Therefore, the first glass 170 is provided at the first opening 18b provided at the top 18 of the cooking chamber 20, the second glass 180 is provided at the third opening 59 provided at the bottom surface 57 of the electrical component cavity 50, and the lens 145 of the camera 140 can pass through the first glass 170 and the second glass 180 (see FIG. Figure 10 ) captures the interior of the cooking chamber 20.

[0143] Furthermore, the transmission of heat in the cooking chamber 20 to the camera 140 may be doubly blocked by the first glass 170 and the second glass 180 , and thus the temperature increase of the camera 140 may be effectively prevented.

[0144] Figure 10 is a view showing that a blocking member is provided between a camera and a cooling fan of an electric component cavity according to one embodiment of the present disclosure, and Figure 11 is a view illustrating that air discharged to the outside through an exhaust duct bypasses a camera without contacting the camera through a blocking member and is discharged to the outside according to one embodiment of the present disclosure.

[0145] like Figure 8 、 Figure 10 as well as Figure 11 As shown, a blocking member 160 is provided between the camera 140 positioned in the exhaust duct 53 and the electric component chamber cooling fan 51 to prevent air discharged to the outside through the exhaust duct 53 from directly contacting the camera 140 .

[0146] The blocking member 160 includes a third coupling portion 161 coupled to the bottom surface 57 of the electric component cavity 50 and a support 163 supporting the exhaust duct 53 to prevent sagging of the exhaust duct 53 .

[0147] The blocking member coupling hole 59b is provided on the bottom surface 57 of the electrical component cavity 50 to which the blocking member 160 is coupled, and the blocking member 160 is coupled to the bottom surface 57 of the electrical component cavity 50 by a fastener B inserted into the third coupling portion 161 and the blocking member coupling hole 59b.

[0148] When air drawn from the outside by the electrical component cavity cooling fan 51 is discharged to the outside through the exhaust duct 53, the blocking member 160 connected to the bottom surface 57 of the electrical component cavity 50 allows the air to be discharged without contacting the camera 140 by blocking a portion of the exhaust duct 53 between the camera 140 and the electrical component cavity cooling fan 51.

[0149] The air drawn from the outside by the electric component chamber cooling fan 51 cools the electric components in the electric component chamber 50 and is then discharged to the outside through the exhaust duct 53. Therefore, the air discharged to the outside through the exhaust duct 53 has a high temperature. When the high-temperature air directly contacts the camera 140, the temperature of the camera 140 increases. Therefore, a blocking member 160 is provided between the camera 140 and the electric component chamber cooling fan 51 to prevent the temperature of the camera 140 from increasing.

[0150] In addition, a supporter 163 supporting the exhaust duct 53 is provided at an upper portion of the blocking member 160 to prevent sagging of the exhaust duct 53 .

[0151] A portion of the camera module 100 is coupled to an upper portion of the exhaust duct 53 , and thus a portion of the exhaust duct 53 to which the camera module 100 is coupled may sag downward, and the support 163 of the blocking member 160 supports the exhaust duct 53 to prevent the sag.

[0152] Figure 12 is a view illustrating that air drawn from the outside by a cooling fan of a camera and a cooling fan of an electric component chamber is discharged through an exhaust duct according to one embodiment of the present disclosure.

[0153] like Figure 12 As shown, the electric component chamber cooling fan 51 draws external air into the electric component chamber 50 through the suction port 12 a of the side panel 12 .

[0154] After the air drawn into the electric component cavity 50 cools the electric components in the electric component cavity 50 , the air is drawn into the exhaust duct 53 by the electric component cavity cooling fan 51 , and the air drawn into the exhaust duct 53 is guided by the exhaust passage 55 and discharged to the outside.

[0155] External air drawn into the inlet 15 of the upper panel 14 by the camera cooling fan 120 moves through the suction flow path 111 , cools the camera 140 , and is then discharged through the outlet 137 .

[0156] Since the electric component cavity cooling fan 51 cools the entire electric component cavity 50 , the electric component cavity cooling fan 51 requires a larger air flow than the camera cooling fan 120 that cools the camera 140 , and thus has a larger size than the camera cooling fan 120 .

[0157] Therefore, the air discharged into the exhaust duct 53 by the electrical component cavity cooling fan 51 has a higher speed than the air discharged into the outlet 137 by the camera cooling fan 120, and thus the air discharged into the outlet 137 is discharged to the outside together with the air discharged into the exhaust duct 53 through the electrical component cavity cooling fan 51.

[0158] Figure 13 is a view showing that a blocking member is integrally provided in a glass support according to another embodiment of the present disclosure, and Figure 14 FIG. 2 is a view showing that a blocking member is integrally provided in a camera bracket according to another embodiment of the present disclosure.

[0159] like Figure 13 As shown, the blocking member 158 is not separately provided but is integrally provided in the glass holder 150 to prevent the air drawn into the exhaust duct 53 by the electric component cavity cooling fan 51 from directly contacting the camera 140 .

[0160] In addition, if Figure 14 As shown, the blocking member 138 is not separately provided but is integrally provided in the camera bracket 130 to prevent the air sucked by the electric component cavity cooling fan 51 and the air discharged into the exhaust duct 53 from directly contacting the camera 140 .

[0161] Figure 15 is a schematic diagram of an oven according to one embodiment of the present disclosure.

[0162] like Figure 15 As shown, the top 18 of the cooking chamber 20 has a first opening 18 b , so that the camera 230 disposed on the top 18 of the cooking chamber 20 captures the interior of the cooking chamber 20 through the first opening 18 b .

[0163] The camera 230 is disposed above the top 18 of the cooking chamber 20, and therefore the width of the first opening 18b should be determined based on the distance between the top 18 of the cooking chamber and the lens 235, the width of the cooking chamber 20, and the distance between the lens 235 and the bottom surface of the cooking chamber 20, so that the food to be cooked in the cooking chamber 20 can be captured via the camera 140.

[0164] When the width of the first opening 18b is f, the distance between the top 18 of the cooking chamber 20 and the lens 235 is g, the width of the cooking chamber 20 is w, and the distance between the lens 235 and the bottom surface of the cooking chamber 20 is h, the width of the first opening 18b preferably satisfies the expression "f≥g×w / h".

[0165] Figure 16 is a side sectional view of an oven according to another embodiment of the present disclosure, Figure 17 is a view showing the interior of an electric component cavity of an oven according to another embodiment of the present disclosure, Figure 18 is an exploded perspective view of a camera module according to another embodiment of the present disclosure, Figure 19 is a view showing that a portion of a camera module according to another embodiment of the present disclosure is coupled to an exhaust duct, and Figure 20 is a view illustrating that a camera according to another embodiment of the present disclosure is cooled by air drawn from the outside through a cooling fan of an electric component cavity.

[0166] like Figures 16 to 20 As shown, the camera module 200 is provided at the top of the cooking chamber 20 to capture food to be cooked in the cooking chamber 20 .

[0167] Figures 2 to 14 The illustrated camera module 100 includes a separate camera cooling fan 120 to cool the camera 140 , but the camera module 200 does not necessarily have a separate camera cooling fan to cool the camera 230 , and thus the camera 230 may be cooled by an electrical component cavity cooling fan 51 disposed in the electrical component cavity 50 to cool the electrical components in the electrical component cavity 50 .

[0168] The camera module 200 includes a suction duct 210 connected to the inlet 15 provided at the upper panel 14 of the main body 10, a camera bracket 220 on which the camera 230 is mounted, the camera 230 installed in the camera bracket 220 to capture the interior of the cooking chamber 20, and at least one of the glasses 250 and 260 provided below the camera 230.

[0169] The suction duct 210 includes a suction flow path 211 provided in the electrical component cavity 50 and communicating with the inlet 15, an outlet 213 through which air sucked into the suction flow path 211 is discharged, a partition wall 215 provided between the suction flow path 211 and the outlet 213, a camera holder coupling hole 217 coupled to the camera holder 220, and a water storage portion 219 that stores water dripping through the inlet 15 to prevent the water from being transferred to the camera 230 through the suction flow path 211.

[0170] The suction flow path 211 communicates with the inlet 15 and guides the external air sucked through the inlet 15 to be introduced to the camera 230 .

[0171] The outlet 213 discharges the air drawn into the suction flow path 211 through the inlet 15 to cool the camera 230 to the outside of the camera module 200 .

[0172] The outlet 213 is provided to face the electric component chamber cooling fan suction port 52 , and the upper end of the outlet 213 is provided to be higher than the upper end of the electric component chamber cooling fan 51 .

[0173] The upper end of the outlet 213 is disposed higher than the upper end of the electric component cavity cooling fan 51 , and the outlet 213 is disposed at an upper portion of the electric component cavity cooling fan suction port 52 .

[0174] The outlet 213 is provided at an upper portion of the electric component cavity cooling fan suction port 52 , and thus external air is sucked through the inlet 15 by the suction force of the electric component cavity cooling fan 51 even though a separate camera cooling fan is not provided in the camera module 200 .

[0175] The partition wall 215 is provided between the suction flow path 211 and the outlet 213 , and thus the air drawn into the suction flow path 211 is not directly discharged through the outlet 213 .

[0176] The camera bracket 220 on which the camera 230 is mounted is set at the lower part of the suction pipe 210, and the suction pipe 210 and the camera bracket 220 are connected by a fastener B, which is fastened to the camera bracket connecting hole 217 set in the suction pipe 210 and the suction pipe connecting hole 225 set in the camera bracket 220.

[0177] Each of the suction flow path 211 and the outlet 213 of the suction duct 210 is provided to communicate with the camera holder 220. The air sucked into the suction flow path 211 is blocked by the partition wall 215 from moving to the outlet 213 and is transferred to the camera holder 220. The air transferred to the camera holder 220 cools the camera 230.

[0178] The air cooling the camera 230 is discharged to the outside of the camera module 200 through the outlet 213 , and the air discharged through the outlet 213 is drawn into the electric component cavity cooling fan suction port 52 and then discharged to the outside of the electric component cavity 50 through the exhaust duct 53 .

[0179] The camera bracket 220 includes a fixing hook 221 fixed to the suction pipe 210, a fixing protrusion 223 fixed to the glass bracket 240 set below the camera bracket 220, a suction pipe coupling hole 225 connected to the camera bracket coupling hole 217 of the suction pipe 210, and a glass bracket coupling hole 227 connected to the glass bracket 240.

[0180] When the fixing hook 221 of the camera bracket 220 is fixed to the suction duct 210 , the fastener B is fastened to the camera bracket coupling hole 217 and the suction duct coupling hole 225 of the camera bracket 220 , and thus the camera bracket 220 is coupled to the suction duct 210 .

[0181] The camera 230 is mounted on the camera bracket 220, and the camera 230 is disposed in the electric component cavity 50, and thus the temperature of the camera 230 may increase due to heat generated by the electric components in the electric component cavity 50. The electric component cavity 50 in which the camera 230 is disposed is disposed above the cooking chamber 20, and thus the temperature of the electric component cavity 50 may increase due to heat generated by the cooking chamber 20.

[0182] When the temperature of the camera 230 rises, a malfunction may occur in the camera 230 and its image quality may deteriorate, and thus it is necessary to cool the camera 230. In this case, the camera 230 is cooled by external air drawn into the inlet 15 by the electrical component cavity cooling fan 51.

[0183] The camera 230 includes a mounting portion 231 mounted on the camera bracket 220 , a body tube 233 extending downward from the mounting portion 231 and having a cylindrical shape, and a lens 235 provided at an end of the body tube 233 to capture the inside of the cooking chamber 20 .

[0184] The lens 235 is provided at the lower portion of the camera holder 220 , and thus the lens 235 may be inserted into the second opening 54 together with the lower portion of the camera holder 220 .

[0185] The lens 235 inserted into the second opening 54 is inserted into the third opening 59 provided on the bottom surface 57 of the electric component cavity 50 and is disposed near the top of the cooking chamber 20 to capture the inside of the cooking chamber 20 .

[0186] At least one of the glasses 250 and 260 is disposed below the camera 230 to allow the camera 230 to capture the inside of the cooking chamber 20 and to block transmission of heat in the cooking chamber 20 to the camera 230 .

[0187] The glasses 250 and 260 include two first glasses 250 fixed to a glass holder 270 to be disposed at upper and lower surfaces of the top 18 and one second glass 260 fixed to a glass support 240 to be disposed between the camera 230 and the first glasses 250 .

[0188] The drawings show the glasses 250 and 260 including two first glasses 250 and one second glass 260, but the number of glasses is not limited thereto. One or at least three first glasses 250 may be provided, and at least two second glasses 260 may be provided.

[0189] In addition, the glasses 250 and 260 may be provided as a single glass without being divided into the first glass 250 and the second glass 260 .

[0190] When the glasses 250 and 260 are provided as a single glass, the glasses 250 and 260 preferably have a thickness of 4 mm or more.

[0191] When the glasses 250 and 260 are divided into the first glass 250 and the second glass 260 , the sum of the thicknesses of the first glass 250 and the second glass 260 is preferably 4 mm or more.

[0192] When the thickness of the glass 250 and 260 is 4 mm or less, the heat reflecting coating layer 255 is provided on one surface of the glass 250 and 260, such as Figure 6 As shown, a heat reflective coating 255 may be provided on both surfaces of the glass 250 and 260, as shown in FIG. Figure 7 shown.

[0193] When the heat reflective coating layer 255 is provided on one surface of the glasses 250 and 260 , it is preferred that the surface on which the heat reflective coating layer 255 is provided faces the cooking chamber 20 .

[0194] In addition, the glasses 250 and 260 may be formed of heat-resistant tempered glass or borosilicate glass to prevent damage caused by heat, and when a plurality of glasses 250 and 260 are provided, only the glass 250 provided closest to the cooking chamber 20 may be formed of tempered glass or borosilicate glass.

[0195] One second glass 260 is fixed to the glass holder 240 , and the glass holder 240 includes a camera holder coupling hole 241 coupled to the camera holder 220 provided at an upper portion of the glass holder 240 , and a fixing hole 243 to which the fixing protrusion 223 of the camera holder 220 is fixed.

[0196] After the fixing protrusion 223 of the camera bracket 220 is fixed to the fixing hole 243 of the glass bracket 240 , the fastener B is fastened to the camera bracket coupling hole 241 of the glass bracket 240 and the glass bracket coupling hole 227 of the camera bracket 220 , and the glass bracket 240 is coupled to the lower portion of the camera bracket 220 .

[0197] The space where the end portion of the body tube 233 of the camera 230 is provided, where the lens 235 is provided, is sealed by the mounting portion 231 of the camera 230 and the glass holder 240 to prevent foreign materials such as dust from entering the lens 235 .

[0198] The first opening 18b is provided on the top 18 of the cooking chamber, the second opening 54 is provided in the exhaust duct 53, and the third opening 59 is provided on the bottom surface 57 of the electrical component cavity 50. The camera 230 captures the configuration and interior of the cooking chamber 20 through the openings 18b, 54, and 59. Figures 2 to 14 The configurations shown are the same, and therefore description thereof will be omitted.

[0199] However, in Figure 4 In the case of the camera module 100 shown, coupling holes 59a and 59b to which the blocking member 160 and the glass holder 150 are coupled are provided around the third opening 59. Figure 18 In the case of the illustrated camera module 200 , the glass support 240 is coupled to the camera support 220 , and no blocking member is applied, and thus it is not necessary to provide a coupling hole around the third opening 59 .

[0200] The glass holder 270 to which the first glass 250 is fixed includes a coupling portion 271 provided at a position corresponding to the glass holder coupling hole 18c, and the glass holder 270 is coupled to the top 18 of the cooking chamber 20 by a fastener B inserted into the coupling portion 271 and the glass holder coupling hole 18c.

[0201] The glass holder 270 is attachable to and detachable from the top 18 of the cooking chamber 20, and therefore, when foreign material is on the first glass 250 disposed above the cooking chamber 20, the glass holder 270 can be separated from the top 18 of the cooking chamber 20 and the foreign material can be removed from the first glass 250.

[0202] Will refer to Figure 17 and 20The air flow for cooling the camera 230 of the camera module 200 is described.

[0203] like Figure 17 and Figure 20 As shown, external air is sucked into the inlet 15 formed in the upper panel 14 of the main body and the suction ports 12 a formed in both side panels 12 of the main body 10 by the electric component cavity cooling fan 51 .

[0204] The air drawn into the suction port 12 a cools the interior of the electric component chamber 50 , is drawn through the electric component chamber cooling fan suction port 52 , and is then discharged to the outside of the electric component chamber 50 through the exhaust duct 53 .

[0205] The air drawn into the inlet 15 is transferred to the camera bracket 220 through the suction flow path 211 to cool the camera 230, and is then discharged through the outlet 213, and the air discharged to the outlet 213 is drawn into the electric component cavity cooling fan suction port 52 and discharged to the outside of the electric component cavity 50 through the exhaust duct 53.

[0206] Although not shown in the drawings, when the space in which the camera 230 is disposed is vacuum due to the vacuum insulation material being foamed around the camera 230 , heat is not transferred to the camera 230 , and thus a configuration for cooling the camera 230 may be omitted.

[0207] According to an embodiment of the present disclosure, a camera is provided above the cooking chamber, so that the interior of the cooking chamber can be clearly captured and the temperature of the camera provided on the cooking chamber can be prevented from increasing.

[0208] Although specific shapes and orientations have been mainly described in the above description of the oven with reference to the accompanying drawings, various modifications and changes may be made by those skilled in the art, and it should be recognized that such modifications and changes fall within the scope of the present disclosure.
