Title: GENERATING AND USING ELECTRICITY DERIVED FROM WASTE HEAT OF AN ELECTRICAL APPLIANCE
Abstract:
A system (101A, 101B) for deriving operating electricity for an electrical appliance (100A, 100B) from wasted heat of the electrical appliance (100A, 100B) comprises a heat generating component (110) of the electrical appliance (100A, 100B), a thermoelectric device (120) thermally coupled with the heat generating component (110), a charge storage device (140) electrically coupled with the thermoelectric device (120), and a real-time parasitic component (157) of electrical appliance (100A, 100B) that is electrically coupled with thermoelectric device (120) and charge storage device (140). Thermoelectric device (120) is configured to thermoelectrically generate electricity from waste heat of heat generating component (110). The waste heat is generated by heat generating component (110) during operation of electrical appliance (100A, 100B). Real-time parasitic component (157) is configured to receive a portion of its real-time operating electricity from thermoelectric device (120) and a portion of its parasitic operating electricity from charge storage device (140).
