BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven, and more particularly, to a cooking chamber volume variable microwave oven capable of changing the volume of the cooking chamber.

In general, a microwave oven is provided with a tray that is rotated by a motor at the bottom of the cooking chamber, and a magnetron that oscillates high frequency is installed in the cavity side plate in the electric cabinet.

In a microwave oven including a tray and a magnetron, high frequency oscillates in the magnetron, and then the high frequency is irradiated into the cooking chamber to cook the food placed on the tray. At this time, the microwave oven is usually irradiated with high frequency to food to increase the cooking efficiency of the food, by rotating the tray by a motor to be evenly irradiated high frequency over the entire food.

4 shows a cooking chamber of a microwave oven according to the prior art.

Referring to FIG. 4, the cooking chamber of the microwave oven according to the related art is formed inside the inner casing 10, and a tray T and a mark netron (not shown) are disposed at one side.

The inner casing 10 consists of a first side casing 10a, a second side casing 10b, a bottom casing 10c, an upper casing 10e and a rear casing 10d.

A magnetron is disposed in the first side casing 10a, and the second side casing 10b is disposed opposite the first side casing 10a.

The rear casing is joined to one surface of the first side casing 10a and the second side casing 10b by joining means, respectively, and the top casing 10e is the first side casing 10a, the second side casing 10b and The upper end of the rear casing (10d) is respectively coupled to the bonding means.

The bottom casing 10c is coupled to each of the lower ends of the first side casing 10a, the second side casing 10b and the rear casing by bonding means, and a tray T is rotatably installed at the center thereof.

At this time, the first side casing (10a), the second side casing (10b), the back casing (10d), the top casing (10e) and the bottom casing (10c) are each coated with a reflective material that reflects high frequencies.
