According to an embodiment of the present disclosure, the first color and the second color may be different. In other words, the color of the first glass 110 and the color of the second glass 120 may be provided differently. Through this, the cooking apparatus 1 of various designs may be implemented. However, the present disclosure is not limited thereto, and the first color and the second color may be the same. Accordingly, the first glass 110 and the second glass 120 may be provided with the same color while being divided by the middle frame 200.
The middle frame 200 may include a base 210 and the column 220. The base 210 may be disposed below the first glass 110 and the second glass 120 to support the first glass 110 and the second glass 120.

The column 220 may be disposed between the first glass 110 and the second glass 120 when the first glass 110 and the second glass 120 are respectively adhered to the middle frame 200. The column 220 may be formed to be recessed. For example, the column 220 may be curved to correspond to the side surfaces of the first glass 110 and the second glass 120. The column 220 may be formed to be curved while being recessed. Because the column 220 is formed to correspond to the side surfaces of the plurality of glasses 110 and 120, the first glass 110 and the second glass 120 may be brought as close as possible to each other. For example, the separation distance between the first glass 110 and the second glass 120 may be minimized. Because the separation distance between the first glass 110 and the second glass 120 is minimized, aesthetics may be improved. When the user looks at the glass assembly 100 from the top of the cooking apparatus, it may be seen that the separation distance between the first glass 110 and the second glass 120 is very small.
However, the column 220 may extend perpendicularly to the base 210 in a Z direction rather than being curved.
The column 220 may include a first curved surface 221, a second curved surface 222, and an upper surface 223. The first curved surface 221 may be a Y-direction surface of the column 220.

The second curved surface 222 may be a −Y-direction surface of the column 220. The second curved surface 222 may be disposed adjacent to the side surface 123 of the second glass 120. The second curved surface 222 may be adhered to the side surface 123 of the second glass 120 by an adhesive member 131b. However, the present disclosure is not limited thereto, and the second curved surface 222 may be in contact with the side surface 123 of the second glass 120 without the adhesive member 131b. A height of the upper surface 223 of the column 220 may be the same as heights of the upper surface 111 of the first glass 110 and the upper surface 121 of the second glass 120. For example, the upper surface 223 of the column 220 may be disposed on the same line in the Y direction as the upper surface 111 of the first glass 110 and the upper surface 121 of the second glass 120.

The coupling protrusion 164 may be formed on the first portion 161 of the first frame 16. The second frame 170 may include a coupling groove 174 provided in a shape corresponding to the coupling protrusion 164. The coupling groove 174 may be recessed from one end of the second frame 170 in the second direction. The coupling groove 174 may be formed on the first portion 171 of the second frame 170.
The coupling protrusion 164 and the coupling groove 174 may increase a coupling area of the first frame 160 and the second frame 170, and through this, the first frame 160 and the second frame 170 may be stably coupled.
