Samsung patents dryer that adjusts heat based on load weight and moisture
Samsung has filed a patent for a clothes dryer that uses weight and moisture sensors to categorize laundry loads. The system starts with a brief initial cycle to measure the load, then adjusts the main drying time and heat to match the specific category of items being dried.
In the filing’s own words
A clothes dryer comprises a drum, a weight detection sensor, a moisture content detection sensor, and a controller. The controller is configured to determine a category for the drying item among a plurality of categories based on the weight of the drying item detected by the weight detection sensor and the residual moisture content information about the drying item obtained by the moisture content detection sensor at a first predetermined time after an initial drying cycle is initiated according to an initial control condition, monitor a reduction state in the residual moisture content information about the drying item obtained by the a moisture content detection circuit based on a reference time and a moisture content threshold defined corresponding to the determined category to determine a drying level for the drying item, and then initiate a main drying cycle according to the control condition corresponding to the determined drying level.
What exactly they claim (claim 1)
1. A clothes dryer, comprising: a drum configured to receive a drying item; a weight detection sensor configured to detect a weight of the drying item in the drum; a moisture content detection circuit configured to obtain residual moisture content information about the drying item in the drum; and a controller configured to: determine a category for the drying item among a plurality of categories based on the weight of the drying item detected by the weight detection sensor and the residual moisture content information about the drying item obtained by the moisture content detection circuit at a first predetermined time after an initial drying cycle is initiated according to an initial control condition, monitor a reduction state in the residual moisture content information about the drying item obtained by the moisture content detection circuit based on a reference time and a moisture content threshold defined corresponding to the determined category to determine a drying level for the drying item, and initiate a main drying cycle according to a control condition corresponding to the determined drying level, wherein each of the plurality of categories is defined by a combination of a plurality of weight classifications defined per a weight range of the drying item and a plurality of residual moisture content classifications defined per residual moisture content information range of the drying item.
