Disclosed is an electronic range including a cavity, in which cooking of food is to be conducted, a heater chamber arranged over the cavity, an axial-flow fan arranged in the heater chamber and adapted to generate a downward flow of air, and a heater arranged outside the axial-flow fan and adapted to generate heat of a high temperature. A convection plate is arranged between the axial-flow fan and the heater. The convection plate serves to control a flow of air circulating in the interior of the electronic range to effectively convect the heat generated from the heater into the cavity during an operation of the axial-flow fan causing a repeated procedure of downwardly introducing the downward flow of air into the cavity, and then upwardly moving the flow of air along a side wall of the cavity. In this electronic range, food disposed in the cavity is heated, using reflection heat generated by the convection plates and convection air generated by the axial-flow fan. Accordingly, it is possible to rapidly cook the food. The convection plates serve to supply hot air at a high flow rate because they have an orifice function. Accordingly, a strong flow of air is established in the cavity. This provides an effect of allowing the cavity to have a uniform temperature distribution in the whole portion thereof.

Electronic range

The present invention relates to a convection fan control method of a microwave oven which is capable of changing discharge direction of the air heated by a heater to a heating object by controlling rotation direction of a convection fan in accordance with types of a dish comprising a cooking time setting process for selecting a dish type of a heating object and setting cooking time, a rotation direction setting process for setting rotating direction of a fan motor which is capable of rotating and reverse-rotating, a fan motor operating process for operating the fan motor in accordance with the set rotating direction, a fan operating process for rotating a fan by the operating of the fan motor, and a cooking process for cooking the heating object for the select cooking time by operating of a heater.
