Title:
非対称加熱効果を有する電気トースター
Document Type and Number:
Japanese Patent JP3983303
Kind Code:
B2
Abstract:
Electric toaster with a first heating element arranged at one side of a toasting compartment and a second heating element arranged at an opposed side of the toasting compartment. The first heating element is divided into two sub-elements. Two diodes and a switch provide the possibility to switch over from a normal two-sided toasting mode to an asymmetric single-sided toasting mode. In the normal mode the switch is closed and the sub-elements receive power only during different half-waves of the mains supply voltage, so that the effective radiant power of the sub-divided first element is equal to the radiant power of the second heating element. In the asymmetric mode the switch is opened and the resistance of the first heating element is greater than the resistance of the second element, as a consequence of which relatively more radiant power is emitted by the first heating element than by the second heating element.
