A method for controlling a home appliance in consideration of a state of a surrounding environment is disclosed. A method for controlling a home appliance according to an exemplary embodiment of the present disclosure includes operating a home appliance using a first operation profile, identifying at least one of a behavior type of a user or a type of sound around the user, using Internet of Things (IoT) communication using 5G communication and artificial intelligence (AI), and changing an operation profile for operating a home appliance to a second operation profile, based on at least one of the identified behavior type of the user or type of sound around the user. According to the present disclosure, in accordance with the state of the surrounding environment, the operation noise can be reduced or the operation time of the home appliance can reduced without increasing the discomfort of the user, and therefore the discomfort of the user due to the operation noise can be relieved.

A method for controlling an expansion valve of a frequency conversion heat pump clothes dryer. The open degree of the valve is adjusted through parameters such as the operation time/power/current at a frequency of the frequency conversion compressor; a reference value of the operation time/power/current at a certain frequency is set, and compared with an actual value of the operation time/power/current at the certain frequency of the compressor; if the actual value of the operation time is less than the set reference value or the actual value of the power/current is greater than the reference value, the open degree of the expansion value is increased; and if the actual value of the operation time is greater than the set reference value or the actual value of the power/current is less than the set reference value, the open degree of the expansion valve is decreased.

A dryer appliance including an air circulation duct is provided herein. The dryer appliance may also include a cabinet, a drum, an air handler, and a heat exchange section. The air circulation duct may define a recirculation loop with the drum. The air circulation duct may define a drum air inlet upstream from the drum and a drum air outlet downstream from the drum. The air circulation duct may further define a predetermined leakage port in fluid communication between the recirculation loop and the interior volume of the cabinet. The air handler may be disposed along the air circulation duct in fluid communication between the drum air outlet and the drum air inlet. The heat exchange section may be disposed along the air circulation duct in thermal communication with air within the recirculation loop.

Dryer appliances, including methods of operation, are provided herein. The dryer appliance may include a cabinet, a drum, a ventilation assembly, an air handler, and a controller. The drum may be rotatably mounted within the cabinet. The drum may define a drying chamber. A ventilation assembly may be attached to the drying chamber. The ventilation assembly may include a conduit defining an exhaust passage in fluid communication with the drying chamber. The conduit may extend from an inlet at the drying chamber to an outlet defined through the cabinet. The air handler may be attached to the conduit in fluid communication with the drying chamber to draw air through the exhaust passage. The controller may be in operable communication with the air handler and the drum, and may be configured to initiate a dry cycle.

There are disclosed a laundry machine and a control method of a laundry machine including a heat pump module having an evaporator, a condenser and a compressor; and a blower for supplying the air heated by the heat pump module to a laundry accommodation unit, the control method including an initial operation step for operating the compressor at a first operation frequency; and a frequency decreasing step for decreasing the operation frequency of the compressor, when one or more of a compressed refrigerant temperature which is a temperature of refrigerant having passed the compressor and a condensed refrigerant temperature which is a temperature of a refrigerant having passed the condenser are a preset temperature of higher.

The present invention encompasses methods and apparati for heating a load (9) such as clothes immersed in a medium (such as water) during a heating period. A method embodiment of the present invention comprises heating the load (9) and medium within an enclosure (10) by subjecting said load (9) and medium to heated air (104) originated from a conventional energy source (1); and applying heat to said load (9) and medium within the enclosure (10) via an AC electrical field, embodied as a capacitor, originated from an RF power source (2).

A dryer appliance is provided including a cabinet and a drum defining a chamber and being rotatably mounted within the cabinet. An inlet duct is fluidly coupled to a chamber inlet and an air handler urges a flow of air through the inlet duct and into the chamber. An induction heating assembly is in thermal communication with the inlet duct and includes an induction coil for generating an electromagnetic field and a heating plate for generating heat when energized by the electromagnetic field. The induction heating assembly may be positioned proximate a rear wall of the chamber or in a heater box below the chamber. In addition, the heating plate may form part of a rear wall of the drum or may be positioned behind the rear wall.

A method for operating a domestic appliance with a housing, a rotationally movable drum disposed in the housing for receiving laundry, a motor for driving the drum, a control device for controlling the motor, and an evaluation unit. The method, once a program of the domestic appliance has started, includes controlling the motor via the controller such that the drum is driven by the motor and the drum is moved by an angle of less than 90 degrees. Upon attaining the angle the motor is de-energised. The method includes detecting a rotational-speed signal of the drum from when the motor is de-energised over a predetermined first period, and evaluating the detected rotational-speed signals via the evaluation unit by forming a value. The method also includes interrupting the program when the value is greater than a predetermined first threshold value.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

A method for processing laundry after completion of a drying cycle includes maintaining residual fluid within an airflow path of the appliance, wherein the residual fluid results from a primary drying cycle. A heat pump system is activated and a blower delivers the residual fluid to the drum. A drum temperature is maintained within the drum at a predetermined temperature range during performance of the after-care cycle.
