Output control for a microwave oven, a hood device and associated lamp

摘要

A wall type microwave oven having a hood device and an output control method thereof are disclosed. The microwave oven includes a first switch section for switching a power supply to a hood motor of the hood device, and a second switch section for switching power supply to a hood lamp of the hood device. A third switch section controls the output of the microwave oven by several stages. A control section switches/controls the third switch section, responsive to a control of the first or second switch section, such that when the microwave oven is operated with the hood motor or said hood lamp, output of the microwave oven is to be a low level. The output control method includes the steps of operating the microwave oven in a high output mode when an operation command thereto is inputted; turning on a hood lamp or a hood motor when there is an operation command thereto is inputted during an operation of the microwave oven in a high output mode, and switching the microwave oven from a high output mode to a low output mode; turning off the hood lamp or the hood motor when a stop command thereto is inputted during an operation of the microwave oven in a low output mode, and switching the microwave oven from a low output mode to a high output mode; and operating the microwave oven in a low output mode when an operation command thereto is inputted during an operation of the hood lamp or the hood motor. Thus, under the limited installation circumferences, it is possible to design the microwave oven capable of making the utmost use the output of the high voltage transformer and to prevent the overload of the microwave oven.
