Samsung patents wireless charging for smart cookers

Patent drawing
Patent drawing from the official filing.

Samsung describes a cooking device that receives power wirelessly from a base station. It uses two capacitors to charge a communication module before the main controller, allowing the device to send data to the base station's display before fully turning on.

Why it mattersThis design allows smart kitchen appliances to communicate their status or settings via a screen before the user interacts with the main unit.

In the filing’s own words

A cooking device that includes a controller configured to, after being activated, control an operation of the cooking device; a communication unit configured to, after being activated, transmit data to a wireless power transmission device; a pickup coil configured to wirelessly receive power from a transmitting coil of the wireless power transmission device; a rectification unit configured to rectify the an alternating current (AC) of the pickup coil corresponding to the power received by the pickup coil, to produce a direct current (DC); a first capacitor configured to be charged in accordance with the DC current produced by the rectification unit to activate the communication unit; and a second capacitor, having a capacitance greater than a capacitance of the first capacitor, configured to be charged in accordance with the DC current produced by the rectification unit to activate the controller, so that the communication unit is activated before the controller.

What exactly they claim (claim 1)

1. A station comprising: a wireless power transmission unit configured to wirelessly transmit power to a cooking device through a transmitting coil; a communication interface configured to receive data transmitted by a communication unit of the cooking device before an activation of a controller of the cooking device; and an output interface including a display unit configured to display the received data before the activation of the controller of the cooking device.
