| 20120097044 | ANTI-BURN/ANTI-JAM ELECTRIC TOASTER WITH ELECTROMAGNETIC LATCH - In a toaster, a toasting carriage is latched during toasting by an electromagnet actuated by a timer control circuit, and released when toasting time has elapsed. One of two rectifying circuits is always live and supplies a DC current to the timer control circuit and another, separate rectifying circuit supplies a DC current to energise the electromagnet when the toasting cycle is initiated. A first switching module switches a current flow through the heating element, while a second switching module isolates the always live rectifying circuit from the heating element. Switches of the first and second switching modules are disposed in an array and are closed by movement of the toasting carriage to the toasting position. More responsive and stable electromagnetic latching contributes to reducing risks associated with a fire that could occur during use of the toaster. | 04-26-2012 |
