Samsung patents dryer that times water drainage based on load weight
Samsung describes a clothes dryer that uses a heat pump to dry laundry while collecting the moisture it removes. The machine weighs the clothes and checks the selected drying setting to calculate exactly when to start a pump that moves the collected water out of the internal tank.
In the filing’s own words
A clothes dryer is provided. The clothes dryer includes a user interface, a drum in which objects to be dried are accommodated, a heat pump including an evaporator, a condenser, and a compressor, the heat pump being configured to supply hot air to the drum, a condensate water tank configured to store condensed water generated by the heat pump, a drain pump configured to pump the condensed water, memory, including one or more storage media, storing instructions, and one or more processors communicatively coupled to the user interface, the drum, the drain pump, and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the clothes dryer to receive a drying course selected by a user input through the user interface, detect a weight of the objects to be dried accommodated in the drum, determine a driving start time of the drain pump based on at least one of the drying course or the weight of the objects to be dried, and drive the drain pump in response to the driving start time being reached.
