Abstract

A method for controlling the operation of a microwave oven. In order to prevent excessive pressure on the lifting device and the weight detection unit, when the weight of food is heavier than a predetermined standard weight, the tray on which the food to be cooked is placed does not rise, so as to prevent the microwave oven from malfunctioning. failure and damage. The method includes the following steps: if an operation start signal is received, turn on the rotating device to rotate the tray; detect the weight of the food placed on the tray; compare the weight of the food with a predetermined limit weight; if the weight of the food is less than the limit weight, drive the elevating device , to raise the tray to a predetermined height; if the weight of the food is heavier than the limit weight, compare the weight of the food with a predetermined maximum allowable weight, and the predetermined maximum allowable weight is greater than the limit weight; if the If said food weighs more than said predetermined maximum allowable weight, said raising means and rotating means are disconnected and an error is indicated. #!

Description

technical field [0001] The present invention generally relates to an operation control method of a microwave oven. In particular, it relates to an operation control method of a microwave oven in which the food on a tray in a microwave oven exceeds a standard weight, and the tray with food in the microwave oven does not rise, so as to prevent overpressure of pressure applied to the raising device and the weight detection unit, thereby eliminating the microwave oven possible malfunction. technical background [0002] The following application documents disclose similar or related technologies. [0003] A microwave oven disclosed in Japanese Utility Model Publication (Unexamined) No. 94-64013 (filing date: February 16, 1993) includes a heating chamber, a tray, a motor, and a rotation / elevation drive. The tray is mounted on a rotation / elevation drive which extends into the heating chamber and a motor is used to rotate and / or raise the tray. After the rotat...
