A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.

A laundry treating appliance for treating laundry according to an automatic cycle of operation includes a cabinet defining a cabinet interior. A drum is rotatable within the cabinet interior, and at least partially defines a treating chamber. The treating chamber has a treating chamber air inlet and a treating chamber air outlet. A drying air circuit is fluidly coupled to the treating chamber air inlet and to the treating chamber air outlet. The laundry treating appliance can include first and second air temperature sensors, at least a first humidity sensor, and a controller operably coupled with the sensors.

A washing machine appliance and nozzle assembly is provided herein. The washing machine appliance may include a cabinet, a tub positioned within the cabinet, a wash basket, and a nozzle assembly. The nozzle assembly may be mounted within the cabinet and configured to provide wash fluid to the tub. The nozzle assembly may include an extendable nozzle, a supply line, and a nozzle valve. The extendable nozzle may be movable between retracted and extended positions. The extendable nozzle may define a fluid path extending in fluid communication between a nozzle inlet and a nozzle outlet. The supply line may extend to the extendable nozzle in fluid communication therewith to provide a flow of wash fluid to the extendable nozzle. The nozzle valve may be positioned within the extendable nozzle in fluid communication with the supply line upstream from the nozzle outlet.

A dryer appliance and a method of detecting a moisture content of clothes in the dryer appliance are provided. The dryer appliance includes a top bearing positioned proximate a front of a rotating drum and temperature and humidity sensors positioned behind the top bearing for measuring a chamber temperature and humidity as well as a temperature sensor for measuring the exhaust temperature. A controller implements a method of detecting the moisture content of clothes within the drum by obtaining the chamber and exhaust temperatures and the chamber humidity, estimating the moisture content using these values, and adjusting at least one operating parameter of the dryer appliance in response to the estimated moisture content of the clothes.

A door of a dryer appliance includes a frame defining a distribution plenum surrounding a transparent window. The frame defines a plurality of inlets on an inner surface and being spaced circumferentially around the frame to provide fluid communication between a drying chamber and the distribution plenum. A plenum outlet provides fluid communication between the distribution plenum and a trap duct for permitting the discharge of heated air from the drying chamber.

A dryer includes a main body, a drying chamber provided inside the main body and configured to accommodate objects to be dried, a conveying unit configured to convey the objects to be dried, a sensor unit configured to sense information on states of the objects to be dried, and a control unit configured to control the conveying unit to move the objects to be dried based on the information sensed by the sensor unit.

A laundry treating apparatus comprises a drum receiving clothes; a fan supplying air to the drum; a heater heating the air supplied to the drum; and a dry level sensing unit determining a dry level of the clothes. A control method comprises setting a dry time; supplying air to the clothes by operating the fan or operating the fan and the heater, and controlled to be performed for the dry time; and resetting the dry time, when the dry level measured by the dry level sensing unit at a time past a preset reference time period from the start of the air supply step is less than a preset reference dry level, wherein resetting the dry time step adds more time to the reference time period.

A disclosed dryer includes a receptacle configured to contain material to be dried, an air duct configured to route recirculating air and/or fresh air to the receptacle, a heating device configured to heat the recirculating air, and at least one sensor. The sensor is configured to determine a relative humidity and/or temperature, and the air duct includes at least one adjusting element configured to modify a portion of recirculating air routed to the receptacle. The dryer further includes a control or regulating device configured to control or regulate the portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device during a drying process. A disclosed method includes controlling a portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device. Further, a mixture of recirculating air and fresh air are varied during heat-up, drying, and cool-down phases.

A washing machine including a tub disposed inside a main body, a drainage pump configured to cause the received water inside the tub to flow to an outside of the washing machine through a drainage passage, a first filter, arrangeable along the drainage passage, to filter out foreign matter equal to or greater than predetermined size from the water, and a second filter, arrangeable along the drainage passage, to filter out foreign matter smaller than the predetermined size from the water. The drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.

A laundry treating apparatus include: a cabinet; a tub disposed in the cabinet; a drum rotatably disposed in the tub, and having a cylindrical portion formed of a ferromagnetic material and a rear wall portion for closing an open rear end of the cylindrical portion, wherein the cylindrical portion has a plurality of through-holes formed therein and allows laundry to be loaded thereinto through an opening portion formed on a front surface; an induction heater disposed in the tub and configured to heat the drum by inducing an eddy current in the cylindrical portion; a duct disposed on an outer side of the tub, having an inlet communicating with an open front surface of the cylindrical portion, and an outlet communicating with the tub through a side surface of the tub surrounding the cylindrical portion; and an air blower configured to suction air, discharged from the drum, into the inlet.
