Claims

[Scope of utility model registration request]

A heating chamber that accommodates an object to be heated, a duct provided across the upper and lower parts of the heating chamber, and an upper and lower duct provided respectively in the upper and lower parts of the heating chamber to communicate the heating chamber and the duct. a hole and a lower small hole, an upper heater and a lower heater that are respectively disposed near the small holes and heat the air blown out from each small hole, and a blowing means that circulates the air in the duct to the heating chamber; It has a control means for controlling the air blowing means and both heaters, and the control means controls the air blowing means so as to blow out the air sucked into the duct from the lower small hole into the heating chamber from the upper small hole. a first state in which the upper heater is activated; and a first state in which the air blowing means is activated and the lower heater is activated so that the air sucked into the duct through the upper small hole is blown out from the lower hole into the heating chamber. A microwave oven characterized in that the microwave oven is configured to alternately switch between a first state and a second state.
