    Abstract: A dryer including a drum; a heat pump including a compressor, evaporator, condenser, and electronic expansion valve; a user interface; a power module to control power supply to the compressor motor and the drum motor; a duct to receive air from the drum so that the received air flows in the duct to be heated by operation of an evaporator and condenser, and to discharge the heated air to the drum; a plurality of temperature sensors to detect temperature of the heat pump, the power module, and the duct; and a controller configured to identify a factor to be controlled from among a plurality of factors that may cause incomplete drying, based on at least one of output data from the plurality of temperature sensors and opening degree data of the electronic expansion valve, and control the user interface to output a notification of the identified factor to be controlled.

    Abstract: Dryer appliances and related methods are disclosed. Such methods may include, or such appliances may be configured for, monitoring a temperature with a thermistor of a primary heat control system of the dryer appliance. The present disclosure also includes determining a relay signal is calling to close a relay and thereby activate a heating system of the dryer appliance and verifying that the relay is closed. The present disclosure further includes allowing a minimum relay on time to elapse after verifying that the relay is closed. The present disclosure also includes determining a temperature gradient of the monitored temperature based on a change in the monitored temperature over the minimum relay on time. The present disclosure further includes detecting a nuisance trip because the determined temperature gradient is negative.

    Abstract: A washing machine includes: a tub; a drum of metal material configured to be rotated in the tub; an induction heater configured to be fixed to the tub in a state of being separated from the drum, and to heat the drum; a first temperature sensor configured to have a tube of metal material heated by the induction heater and a thermistor disposed in the tube, at least a part of the tube being exposed between the tub and the drum; a second temperature sensor configured to be disposed in a position further away than the first temperature sensor from the induction heater in a circumferential direction, and detect a temperature of air between the tub and the drum; and a controller configured to control the induction heater based on a first detection value of the first temperature sensor and a second detection value of the second temperature sensor.

    Abstract: A dryer appliance including a slide bearing assembly mounted to a top bearing for supporting a rotating drum and including a wear indication device is provided. The slide bearing assembly includes a contact circuit including two electrical leads positioned on a top bearing of the dryer appliance. A slide bearing is positioned over the contact circuit for supporting a drum during rotation and maintaining an open circuit between the two electrical leads. A controller monitors the resistance across the two electrical leads, determines that a slide bearing failure has occurred when the resistance drops (e.g., due to worn slide bearings), and notifies the user accordingly.
