Abstract

The heating temp. control method for microwave oven includes three stages: fan motor driving stage, starting from that internal temp. of heating chamber is reached to set pre-heating temp. driving fan motor in first specific period of time; heater driving stage, after the fan motor driving stage is completed, taking drive stop of fan motor as starting point, simultaneously driving grill heater and convection heater in second specific period of time; and repeated execution stage, according to the cooking time inputted by user repeatedly executing the above-mentioned two stages to heat food uniformly.

Description

technical field [0001] The present invention relates to a method for controlling the heating temperature of a microwave oven, more specifically, an invention about a method for controlling the heating temperature of a microwave oven that heats the heating chamber by controlling a fan motor and a heater in a convection mode microwave oven. Background technique [0002] Generally, a microwave oven is a device for heating food through microwaves. A magnetron (magnetron) is arranged in the electric control room, and the above-mentioned magnetron generates microwaves to irradiate the inside of the cooking chamber; the bottom surface of the above-mentioned cooking chamber is provided with a tray for placing cooking containers. In addition, the lower part of the tray is provided with a tray motor for rotating the tray. Then the food placed on the tray rotates together with the tray, so that the microwave irradiated in the cooking chamber can be evenly transmitted to the food in the...
