Latest Patents

Wai H Li holds a patent for an electric toaster with an asymmetric heating effect. This invention features a first heating element arranged on one side of the toasting compartment and a second heating element on the opposite side. The first heating element is divided into two sub-elements, allowing for versatile toasting options. The design includes two diodes and a switch that enables a transition from a normal two-sided toasting mode to an asymmetric single-sided toasting mode. In normal mode, the switch is closed, and the sub-elements receive power during different half-waves of the mains supply voltage. This ensures that the effective radiant power of the sub-divided first element matches that of the second heating element. In asymmetric mode, the switch is opened, resulting in the first heating element emitting more radiant power than the second.
