Problems solved by technology

[0011] However, the prior art microwave heating temperature compensation method has the following problems: most of the heating sources for heating the food in the cavity of the microwave oven are located at the upper end of the cavity, so after heating the food for a certain period of time, it will be found that the upper end of the food receives less heat than the lower end. More
Therefore, the grilling effect on the bottom surface of the food is not very good, and satisfactory cooking results cannot be obtained.

Embodiment Construction

[0020] The microwave oven heating time compensation method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0021] After the user uses the function keys on the microwave oven to select cooking, and presses the start key, the heater, magnetron, fan motor, and turntable motor of the microwave oven start to drive. The rotating motor (not shown) that rotates the food plate and the fan motor that drives the fan for cooling the magnetron (not shown) are driven when the user inputs the cooking signal. Moreover, the heater continues to rotate after the temperature in the cavity reaches the set temperature until the cooking is finished.

[0022] Instead, as in image 3 As shown, the heating process of the heater is as follows: that is, the sleeve heater 40a arranged at the upper end of the cavity works until it reaches the temperature set by the user, and the upper sleeve heater 40a, after a ce...

Abstract

The present invention provides a microwave oven warming time compensation process characterized by that, the barbecue effect is improved by extending the actuation time of the lower sleeve heater, when the user requested in-chamber temperature reaches the specified temperature, the microwave oven lower sleeve heater is made to work for another period of time, by the conversion movement of ON/OFF for realizing the heating energy till the completion of the cooking procedure. The invention can increase the barbecue effect on the bottom surface of the cooked food, thus acquiring the food through uniformly heating.

Description

technical field [0001] The invention relates to a heating method for a microwave oven, in particular to a heating time compensation method for a microwave oven which continues to drive a lower sleeve heater when the temperature in a cavity of the microwave oven reaches a predetermined temperature, so as to improve the grilling effect of food. Background technique [0002] In general, a microwave oven is a device that generates microwaves from an electric current, and injects the microwaves into a heating chamber to heat food. Such a microwave oven has many functions due to the diversification of heating characteristics, and a heater is provided in order to heat food at a higher temperature. A microwave oven with a heater overcomes the single heating characteristic of utilizing microwaves, and can heat food at a higher temperature, or grill the food surface. The above-mentioned microwave oven cooks by driving the magnetron to generate microwaves, or by using the heat release...
