Samsung patents dryer that adjusts electric phases to balance load
This filing describes a dryer that uses multiple electrodes around the drum to dry clothes. It applies different electrical phases to these electrodes and automatically adjusts them if the system detects an imbalance or power backflow.
In the filing’s own words
A dryer includes a drum configured to accommodate an object to be dried, a multi-phase circuit, and a controller. The multi-phase circuit includes a plurality of electrodes disposed outside the drum and spaced apart from each other, and a power supply configured to apply a voltage to the plurality of electrodes. The controller controls the power supply to apply, to each electrode of the plurality of electrodes, a respective voltage among multi-phase voltages such that voltages applied to two adjacent electrodes differ in phase. Based on a voltage for determining an impedance balance of the multi-phase circuit exceeding a reference voltage or based on a backflow of power from the plurality of electrodes to the power supply, the controller adjusts a phase of the voltage applied to at least one electrode of the plurality of electrodes.
What exactly they claim (claim 1)
1. A dryer comprising: a drum configured to accommodate a drying object; a multi-phase circuit comprising: a plurality of electrodes arranged outside the drum and spaced apart from each other, and a power supply configured to apply a voltage to the plurality of electrodes; and a controller configured to: control the power supply to apply, to each electrode of the plurality of electrodes, a respective voltage among multi-phase voltages, wherein the voltages applied to two adjacent electrodes of the plurality of electrodes differ in phase, and based on a voltage for determining impedance balance of the multi-phase circuit exceeding a reference voltage or based on a backflow of power from the plurality of electrodes to the power supply, adjust a phase of the voltage applied to at least one electrode among the plurality of electrodes.
