Problems solved by technology

However, even when the turntable is paused, there is still localized heating, so that more or less uneven object temperatures occur
So in reality, heating the object while turning the turntable results in a change in impedance
Specifically, there is a trade-off relationship between eliminating the problem of temperature unevenness and improving operational efficiency, and therefore, it is difficult to achieve energy saving in simultaneous heating

Abstract

The invention relates to a cooking device comprising a body, a microwave generator, a rotable antenna, a current / voltage detection unit and a control unit, wherein the body forms a cooking box incluing a plurality of zones; each one of the zones is used for containing the objects; the microwave generator generates the microwave; the rotable antenna radiates the microwave generated by the microwave generator to the cooking box, and has directivity; the current / voltage detection unit and a control unit detects the change of the current or voltage of the microwave generating unit related with the position of the rotable antenna when the rotable antenna performs on rotation; and the control unit determines the position of the rotable antenna when the microwave generator gets the operation efficiency being greater than the preset value according to the change of the current or voltage detected by the current / voltage detection unit, and suspends the rotable antenna at the determined position.

Description

technical field [0001] The present invention relates to cooking devices. Background technique [0002] A cooking device (heating / cooking device) such as a microwave oven includes various types of heating units such as those microwave cooking using microwaves supplied from a magnetron, oven cooking using heat radiated from a heater, and steam cooking using steam, And be able to cook objects using various types of cooking methods. [0003] For example, JP2009-257634A discloses a cooking method in which objects having different temperatures are simultaneously heated (simultaneous heating). With this method, it is possible to simultaneously heat each object to an appropriate temperature by one heating. [0004] Also, JP2000-164335A discloses a technique in which a turntable for diffusing microwaves is paused based on a change in a current value of a magnetron while heating an object uniformly at a temperature in consideration of the shape of the object and the position where t...
