    • A drink can induction heating apparatus includes a ferrite core having a plurality of projected portions and recesses formed between the adjacent projected portions. When a drink can is set in a position to be heated, each of the projected portions is oriented toward a longitudinal axis of the drink can and a particular portion of a circumferential wall of the drink can. The apparatus further includes a saddle-shaped heating coil which is partly received in the recesses of the ferrite core and covers a region around the foregoing particular portions of the drink can in a non-contact manner, and an inverter for feeding the AC power to the heating coil. The inverter is arranged to produce the AC power at a resonance frequency which corresponds to one of 5 kHz to 15 kHz where equivalent resistance values of an aluminum can and a steel can approximate to each other.
    • 饮料可以感应加热装置包括铁氧体磁芯,其具有形成在相邻突出部分之间的多个突出部分和凹部。 当饮料罐被设置在待加热的位置时,每个突出部分朝向饮料罐的纵向轴线和饮料罐的周向壁的特定部分定向。 该装置还包括鞍形加热线圈,其部分地容纳在铁氧体磁芯的凹部中,并且以不接触的方式覆盖饮料罐的上述特定部分周围的区域,以及用于将AC电力馈送到 加热线圈。 逆变器被配置为产生相当于5kHz至15kHz之一的谐振频率的交流电力,其中铝罐和钢的等效电阻值可以相互接近。
