[0093] While the camera (140) of the cooking device (1) is capturing the interior of the cooking chamber (40), light from the outside of the cooking device (1) may pass through the outer glass (111) and then be reflected from the inner glass (121) and enter the camera (140). The image of the interior of the cooking chamber (40) captured by the camera (140) may be damaged by light entering the camera (140) from the outside of the cooking device (1).

[0094] Referring to FIG. 10, the door (100) of the cooking appliance (1) according to one embodiment of the present disclosure may further include a polarizing member (151, 152). The polarizing member (151, 152) may include a first polarizing member (151) and a second polarizing member (152).

[0095] As the camera (140) is placed between the outer glass (111) and the inner glass (121) of the door (100), light from the outside of the cooking device (1) can pass through the outer glass (111) and be reflected by the inner glass (121) and then enter the camera (140). When light from the outside of the cooking device (1) enters the camera (140), the camera (140) can capture not only an image from the light inside the cooking chamber (40), but also an image from the light from the outside of the cooking device (1) reflected by the inner glass (121).

[0096] The first polarizing member (151) and the second polarizing member (152) can prevent images from being captured by the camera (140) due to external light of the cooking device (1).

[0097] The first polarizing member (151) may be provided on the outer body (110). For example, the first polarizing member (151) may be positioned on the back surface of the outer glass (111). The first polarizing member (151) may be provided to transmit light vibrating in a first direction. The first polarizing member (151) may be provided to absorb or reflect light vibrating in a second direction different from the first direction. For example, the first polarizing member (151) may include a polarizing film.

[0098] The second polarizing member (152) may be placed on one side of the camera (140) facing the cooking chamber (40). The second polarizing member (152) may be positioned in the camera opening (136a) of the camera holder (136).

[0100] The second polarizing member (152) may be provided to absorb or reflect light vibrating in the first direction transmitted by the first polarizing member (151). The second polarizing member (152) may be provided to block a portion of the light incident on the camera (140). For example, the second polarizing member (152) may include a linear polarizing plate. For example, the second polarizing member (152) may include a polarizer prepared by printing a polarizing film on glass. The second polarizing member (152) may be provided to allow light passing through the inner glass (121) from the inside of the cooking chamber (40) to pass therethrough, and may be provided to prevent light passing through the first polarizing member (151) from passing therethrough.

[0101] According to this configuration, the cooking appliance (1) according to one embodiment of the present disclosure can primarily polarize light from the outside of the cooking appliance (1) by the first polarizing member (151), and the light that passes through the first polarizing member (151) and is reflected by the inner glass (121) and then enters the camera (140) is blocked by being absorbed or reflected by the second polarizing member (151), thereby preventing the image of the inside of the cooking chamber (40) captured by the camera (140) from being damaged by external light.

[0102] Specifically, light from the outside of the cooking device (1) passes through the first polarizing member (151), and light vibrating in the first direction passes through, and light vibrating in the second direction is absorbed or reflected, thereby having polarity. Light that passes through the first polarizing member (151) and is reflected by the inner glass (121) and then enters the camera (140), i.e., light vibrating in the first direction passes through the second polarizing member (152) and is absorbed or reflected, so that light from the outside of the cooking device (1) can be blocked from entering the camera (140). In addition, light inside the cooking chamber (40) vibrates in the first direction and is absorbed or reflected by the second polarizing member (152) after passing through the inner glass (121), but light vibrating in the second direction can pass through the second polarizing member (152), so among the light inside the cooking chamber (40), light vibrating in the second direction can be incident on the camera (140).

[0103] Accordingly, the cooking device (1) according to one embodiment of the present disclosure can block light from the outside of the cooking device (1) from entering the camera (140) and is provided so that light from the inside of the cooking chamber (40) can enter the camera (140), thereby preventing the image of the inside of the cooking chamber (40) from being damaged by light from the outside of the cooking device (1).
