Document Type and Number:
WIPO Patent Application WO/2010/139156
Kind Code:
A1
Abstract:
A toaster cover control device with fireproofing function comprises a cover sliding-frame or a cover opening-closing mechanism and a power switch (K), a cover switch (K1) and a control circuit that are provided in the toaster. The said control circuit is provided with a microprocessor. An output terminal of the control circuit is connected with a transistor (Q1). The said control circuit is connected with a sensor (S). The sensor detects the temperature of the toaster. The control circuit provides a control signal when the detected temperature exceeds the set temperature value, so that a circuit controlling cover action keeps the cover closed. The cover can be opened normally when the detected temperature is lower than the set temperature value. It is also provided with an application method of the said control device.
