Hereinafter, the operation of the electric oven range including the convection part formed as described above will be described. First, referring to the operation of the top burner unit 100 installed at the upper end of the electric oven range, the user places the container containing the food on the upper surface of the top plate 110, the operation knob 220 of the control unit 200 Operate the burner 120 by operating.

When the burner 120 is operated, the heat emitted from the burner 120 heats the container containing food through the upper plate 110. As such, the top burner unit 100 cooks the food contained in the container with radiant heat transferred directly from the burner 120 to the container containing the food and conduction heat transferred from the container to the food.

On the other hand, when looking at the operation of the oven unit 300 of the electric oven range, when the user grips the door handle 312 and pulls forward, the oven door 310 is rotated downward to the front of the oven unit 300 Open. When the front surface of the oven unit 300 is opened, the user places food to be cooked inside the oven cavity 320 and rotates the oven door 310 upward to seal the oven unit 300.

When the oven unit 300 is sealed, the user operates the manipulation knob 220 provided in the controller 200 to operate a plurality of heaters provided in the oven unit 300. That is, when the user manipulates the manipulation knob 220, a plurality of heaters provided inside the oven unit 300 emits heat while electricity is supplied to the oven unit 300.

The heat emitted from the plurality of heaters increases the internal temperature of the oven cavity 320 sealed to a temperature necessary for cooking food. When the internal temperature of the oven cavity 320 rises, the food placed in the oven cavity 320 is cooked.

At this time, when electricity is applied to the electric oven range, the convection motor 520 provided on the rear side of the rear plate 350 generates rotational power. When the convection motor 520 generates the rotational power, the generated rotational power is transmitted to the convection fan 510 which is axially coupled with the convection motor 520 so that the convection fan 510 rotates. When the convection fan 510 is rotated, the internal air of the oven cavity 320 is sucked through the suction port 540 formed at the front of the fan housing 530 by the suction force generated by the rotation of the convection fan 510. do.

The outer circumferential surface of the suction port 540 is bent to the inside of the fan housing 530 so that external air can be easily sucked into the fan housing 530. Outside air that is easily sucked in flows toward the center of the convection fan 510. Air flowing toward the center of the convection fan 510 is discharged to the outer circumferential surface by the rotation of the convection fan 510. Since the air discharged to the outer circumferential surface is formed in a shape in which the inclination angles of the center portion of the fan housing 530 and the fan blade 516 correspond to each other, most of the air sucked in is guided by the discharge duct 550 so that the convection portion 500 is provided. Discharged to the outside.

That is, almost all of the sucked air is discharged, so that almost perfect air flow is generated. In addition, the discharge duct 550 is formed in a curved shape of Archimedes so as to increase the distance from the center in proportion to the rotation angle, so that a larger amount of air is discharged in a wider range.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the shape of the fan housing 530, the discharge duct 550 may be discharged to the right side from the upper half of the fan housing 530, and may be discharged to the left side from the lower half.

As described in detail above, the convection portion structure of the electric oven range according to the present invention is formed such that the central portion of the fan housing provided in the convection portion is inclined obliquely in a shape corresponding to the shape of the fan blade, and the outer circumferential surface of the suction port is inside the convection portion. Is formed by bending. The outer circumferential surface of the discharge duct is shaped into a curved shape of Archimedes, so that a larger amount of air is discharged in a wider range.

Therefore, most of the air sucked into the convection portion is discharged to the outside of the convection portion, that is, inside the oven cavity. Most of the air sucked into the convection part is discharged to a wider range, thereby smoothing the flow of the air inside the oven cavity.

In addition, as the internal air flows smoothly in the oven cavity, the tropical air is smoothed, and the food is cooked evenly, and the cooking speed of the food is increased.

In addition, since the amount of air sucked into the convection part is mostly discharged into the oven cavity, the efficiency of the convection part may be improved.
