Alternatively, the camera 80 may be cooled sequentially from the bottom to the top, that is, from the lens 85 to the camera substrate 82.

As described above, the lower part of the camera 80, which receives the most heat because it is close to the cooking chamber 40, is cooled first, so the cooling efficiency of the camera 80 can be increased.

The lower housing 121 may include a lower opening 126 formed in the lower part of the camera accommodation space 124. The lower opening 126 may be formed in the lower part of the camera receiving portion 123. The camera 80 accommodated in the camera accommodation space 124 can photograph the interior of the cooking chamber 40 through the lower opening 126.

The lower opening 126 may be open to allow air to flow. That is, a blocking member such as glass may not be provided in the lower opening 126. Since no blocking member such as glass is provided in the lower opening 126, the camera 80 can be installed closer to the cooking chamber 40.

According to this embodiment, the lens 85 of the camera 80 may be disposed at a height corresponding to the lower opening 126. Depending on the embodiment, the lens 85 of the camera 80 may be disposed lower than the lower opening 126. Additionally, depending on the embodiment, a blocking member (not shown) may be provided in the lower opening 126 to block the lower opening 126. The blocking member may be formed of a transparent material.

A lower cooling passage 129 may be formed between the lower opening 126 and the transparent portion 17 provided on the upper wall 12 of the inner case 11.

Air sucked from the outside of the main body 10 by the camera cooling fan 90 is supplied to the upper surface of the transparent unit 17 through the lower cooling passage 129, thereby cooling the transparent unit 17. Accordingly, it is possible to obtain the effect of blocking heat transmitted to the camera 80 from the transparent unit 17. Additionally, the lens 85 at the bottom of the camera 80 can be cooled more efficiently by the airflow that rises again after descending to the viewing unit 17.

In addition, foreign matter attached to the surface of the lens 85 can be effectively cleaned from the lens 85 by the U-shaped airflow descending and rising around the lens 85. The transparent portion 17 has an upper wall 12. ) can be formed by a transparent member mounted on the opening. The transparent member may be formed of various materials capable of seeing through, and the transparent member may include at least one or more laminated glasses 18. At least one glass may be made of heat-resistant tempered glass or borosilicate glass. An air insulation layer may be formed between at least one glass. The transparent portion 17 can see through materials other than glass and may be made of a material such as heat-resistant plastic.

The cooking appliance 1 may include a sealing member 150 that seals the lower cooling passage 129 so that air in the lower cooling passage 129 does not leak into the electrical equipment compartment 50. If the air in the camera cooling duct 100 leaks into the exhaust space 52 of the electrical system 50 through the lower cooling passage 129, not only does a pressure loss in the camera cooling duct 100 occur, but also the exhaust space 52 This may interfere with the flow of air discharged to the outside of the main body 10. In other words, if the air flow through the camera cooling fan 90 and the camera cooling duct 100 and the air flow through the battlefield cooling fan 60 and the battlefield duct 70 are not separated from each other, the cooling efficiency of each is It may fall.

The sealing member 150 may seal the lower cooling passage 129 so that air in the lower cooling passage 129 does not leak into the electrical equipment compartment 50. The sealing member 150 is made of an elastic material such as rubber, and may be in close contact between the bottom surface of the housing 110 and the top surface of the upper wall 12. Specifically, the upper surface of the sealing member 150 is in close contact with the bottom surface of the camera receiving portion 123 of the housing 110, and the lower surface of the sealing member 150 is glass forming the upper wall 12 or the transparent portion 17. It can be closely adhered to the upper surface of (18).

The sealing member 150 has a ring shape with a hollow 151, and the camera 80 can photograph the inside of the cooking chamber 40 through the hollow 151. The sealing member 150 may be mounted in the opening 31 of the base plate 30.

The suction duct 130 may be coupled to the housing 110 to suck air from the outside of the main body 10 and guide it to the housing 110. The suction duct 130 can suck air from the outside of the main body 10, where the temperature is relatively lower than that of the electrical equipment room 50.

Accordingly, the camera 80 can be cooled more effectively than other electrical components. The suction duct 130 can suck in external air from the rear of the main body 10. For this purpose, the suction duct 130 may be coupled to the rear plate 25 that forms the rear of the main body 10. An external air intake port 25a (FIG. 16) may be formed on the rear plate 25 to allow air outside the main body 10 to be sucked in. The outside air inlet 25a may be formed to be more recessed than the surrounding area of the outside air inlet 25a so that outside air can be efficiently sucked in. The outdoor air inlet 25a may be formed to be recessed by 3 mm or more than the surrounding area of the outdoor air inlet 25a.

In this way, since the suction duct 130 sucks air from the rear of the main body 10, foreign substances such as water or oil can be prevented from entering the camera 80 or the camera cooling fan 90.

The discharge duct 140 may be coupled to the housing 110 to discharge air that cools the camera 80 from the housing 110. The exhaust duct 140 can discharge air into the battlefield space 51 of the battlefield room 50. As the exhaust duct 140 discharges air into the battlefield space 51, the air discharged from the exhaust duct 140 is blown into the exhaust space 52 of the battlefield room duct 70 by the blowing force of the battlefield cooling fan 60. ) may collide with or not merge with the air discharged forward. Accordingly, the cooling efficiency of the electrical equipment room by the electrical equipment room cooling fan 60 and the electrical equipment room duct 70 may not be reduced.

In particular, the discharge duct 140 may discharge air toward the circuit board 3 disposed in the battlefield space 51. The circuit board 3 is an electrical component that is relatively vulnerable to heat. As described above, the air flowing by the camera cooling fan 90 is air sucked directly from the outside of the main body 10, so it may have a relatively lower temperature than the air flowing by the battlefield cooling fan 60. In this way, by supplying low-temperature air flowing by the camera cooling fan 90 to the circuit board 3, the circuit board 3, which is vulnerable to heat, can be efficiently cooled.

However, depending on the embodiment, the discharge duct 140 may be omitted from the camera cooling duct 100. If the discharge duct 140 is omitted, air may be discharged into the battlefield space 51 through the outlet 116 of the housing 110.

An outlet 137 of the suction duct through which air flows out from the suction passage 132 may be formed at the other end 136 of the suction duct 130. The outlet 137 of the suction duct may be connected to the inlet 115 of the housing 110.

One end 133 of the suction duct 130 may be coupled to the rear plate 25 that forms the rear of the main body 10. For this purpose, a coupling portion 135a and a coupling hole 135b that can be coupled to the rear plate 25 may be formed at one end of the suction duct 130. Separate fastening members such as screws, pins, rivets, and bolts may be coupled to the coupling hole 135b.

The other end 136 of the suction duct 130 may be coupled to the housing 110. A coupling portion 138a and a coupling hole 138b for coupling with the housing 110 may be formed at the other end 136 of the suction duct 130.

That is, the electronic room cooling fan 60 can form a first air flow (see the double line arrow in FIG. 17, the double line arrow in FIG. 20, and FIG. 18).

When the camera cooling fan 90 is driven, air outside the main body 10 is sucked into the camera cooling duct 100, cools the camera 80, and can be discharged into the battlefield space 51. That is, the camera cooling fan 90 can form a second air flow (see the single-line arrow in FIG. 18, the single-line arrow in FIG. 20, and FIG. 19).

The housing 110 of the camera cooling duct 100 may include a camera accommodating portion 123 that forms a camera accommodating space 124 accommodating the camera 80.
