The present invention relates to an electric oven, and more particularly, to an oven door structure in which a support bracket for supporting a door top bracket mounted on an upper surface of an oven door is provided at a center portion of a rear side of a windshield.

In general, an electric oven is dried by using various heaters and high frequency generators such as ceramic heaters, sheath heaters, and halogen heaters that are electrically operated after the cooking material is sealed. 조리) As a cooking appliance that heats cooking ingredients, the cooking speed is heated at the same time as the outside and inside of the cooking ingredients, and the heat efficiency is high.

1 is a front view showing an oven door of a conventional electric oven being opened. As shown in the drawing, the electric oven 10 is formed in a substantially rectangular shape, and a space for cooking with food stored therein. The phosphorus cooking chamber 20 is formed.

In addition, the opened front surface of the cooking chamber 20 is selectively shielded by the oven door 30. The oven door 30 is formed in a substantially rectangular shape to shield the front of the cooking chamber 20, the lower end of the oven door 30 is hinged to the lower end of the cooking chamber front the oven door 30 Becomes rotatable up and down. In addition, the opened front surface of the cooking chamber 20 is selectively shielded by the rotation of the oven door 30.

In addition, a door handle 32 is formed at the upper end of the oven door 30. The door handle 32 is formed to protrude forward to facilitate the user's gripping by facilitating rotation of the oven door 30.

 The control panel 40 is deflected on the upper front surface of the electric oven 10, that is, the upper front surface of the cooking chamber 20. The control panel 40 forms a part of the front appearance of the electric oven 10 and at the same time displays a manipulation knob 42 for controlling the operation of the electric oven 10 and a display 44 for displaying an operation state. It is to provide a space provided with the back.

An electrical equipment chamber (not shown) is formed behind the control panel 40, that is, above the cooking chamber 20. The electric room is a place where the electric devices and components for the operation of the electric oven 10 is mounted, the magnetron, the high-pressure transformer and the fan assembly for the cooling is installed.

Figure 2 is a partial perspective view showing a structure in which the door top bracket is fixed to the oven door according to the prior art, looking at the coupling structure of the oven door and the door top bracket with reference to the drawings, the front of the oven door 30 Windshield 34 is formed.
