    • A method and apparatus for regulating a microwave oven to a predetermined output power level. The anode current or a voltage corresponding to it is monitored to provide a signal indicative of the actual output power of the magnetron. Time is divided into a sequence of equal time intervals, each interval corresponding to fixed number of ac line cycles. In accordance with the signal, the number of ac cycles to be supplied to the power supply for each interval to regulate the output power towards the regulated level is determined. The determined number of cycles are supplied by switching at the zero current crossings between the line and the power supply. The switching is executed so that the supplied ac cycles are distributed substantially uniformly over the particular time interval.
    • 一种用于将微波炉调节到预定输出功率电平的方法和装置。 监测阳极电流或对应于其的电压以提供指示磁控管的实际输出功率的信号。 时间分为等时间间隔的序列,每个间隔对应于ac线周期的固定数量。 根据该信号,确定为每个间隔提供给电源的交流循环数量以调节朝向规定电平的输出功率。 通过在线路和电源之间的零电流交叉开关来提供确定的周期数。 执行切换,使得所提供的交流周期在特定时间间隔上基本均匀地分布。

    • An oven comprises a cooking chamber, first and second energy sources, a cooling fan, and a controller. The first energy source provides radiation heating in the cooking chamber, and the first energy source has a low mass for rapid heating. The second energy source provides convection heating in the cooking chamber, and the second energy source has a high mass heating element and a convection fan for moving air through the cooking chamber during convection heating. The cooling fan moves cooling air over the first energy source. The controller energizes the first and second energy sources during at least initial convection heating so that the first energy source rapidly heats the cooking chamber in order to facilitate the initial convection heating and to eliminate the need to pre-heat the cooking chamber.
    • 烤箱包括烹饪室,第一和第二能量源,冷却风扇和控制器。 第一能源在烹饪室中提供辐射加热,并且第一能量源具有用于快速加热的低质量。 第二能源在烹饪室中提供对流加热,并且第二能量源具有高质量加热元件和用于在对流加热期间通过烹饪室移动空气的对流风扇。 冷却风扇将冷却空气移动到第一能量源上。 控制器在至少初始对流加热期间激励第一和第二能量源,使得第一能量源快速加热烹饪室,以便于初始对流加热,并且消除对烹饪室预热的需要。
