A control method for a clothes drying apparatus that aims to solve the problem of a load being prone to entangling when an existing clothes drying apparatus is used for drying a large load. For this purpose, the control method for a clothes drying apparatus includes: determining the size of a load in a load determining stage; and when the load is a large load, controlling a drying drum to rotate unidirectionally in a first heating stage, and controlling the drying drum to alternately rotate normally and reversely in a second heating stage. Accordingly, a drying effect can be guaranteed while the load is effectively prevented from being knotted and entangled, and the drying time is shortened.

A combination washer/dryer appliance may include a cabinet, a tub, a laundry basket, a heater, and a controller. The laundry basket may be rotatably mounted within the tub and define a chamber for receipt of articles for washing or drying. The controller may be operably coupled to the heater and configured to initiate a wash/dry operation. The wash/dry operation may include initiating a wash/dry operation for articles within the laundry basket. The wash/dry operation may include a wash cycle and a dry cycle. The wash/dry operation may further include determining completion of the wash cycle and directing a tumble cycle of the laundry basket in response to determining completion of the wash cycle. The wash/dry operation may still further include determining a user drying preference during the tumble cycle of the laundry basket and adjusting the wash/dry operation based on the determined user drying preference.

A washing machine according to an aspect of the disclosure includes: a tub; a drum rotatably provided inside the tub; a heater configured to heat water; a circulating pump configured to circulate a part of the water stored in the tub; a water level sensor configured to sense a water level of water in the tub; and a controller configured to control the circulating pump to circulate the part of the water stored in the tub, and control revolutions per minute (rpm) of a motor of the circulating pump based on a water level of the water while the water stored in the tub circulates and the heater is driven.

A clothing management apparatus includes a cabinet, a drum an induction heater that includes a housing accommodating a coil, a first duct provided outside the drum and having an inlet communicating with an inner space of the drum, a chamber provided outside the drum and including a first inlet communicating with the first duct, a first outlet communicating with the inner space, a first flow path connecting the first inlet and the first outlet, a second inlet communicating with an outer space of the drum, a second outlet communicating with the housing, and a second flow path connecting the second inlet and the second outlet, a partition wall provided in the chamber and dividing the first flow path and the second flow path, a first impeller in a flow path communicating with the first flow path, and a second impeller in a flow path communicating with the second flow path.

An information processing method includes: selecting M blocks as M selected blocks from among N blocks for driving at least one of an actuator or a heater included in an apparatus, in accordance with an input operation performed by an operator; generating an application, by setting the order of the M selected blocks in accordance with an input operation performed by the operator; consulting a rule that prohibits two or more given blocks from being executed in a given order, and when information included in the application that indicates the order of the M selected blocks correlates with the given order, modifying the application by changing the order in which each of the M selected blocks is executed; and outputting the modified application.

A laundry washing machine having configured to receive a laundry cycle selection from a user interface; identify the cycle selection; upon receiving a normal laundry cycle selection, select a respective program comprising default instructions for: opening the valve one or more times to fill the drum to a default normal maintenance phase liquid level, and operating the drum motor during a normal maintenance phase to rotate the drum; and upon receiving a selection of the whites laundry cycle, select a respective program comprising default instructions for: opening the valve one or more times to fill the drum to a default whites maintenance phase liquid level, and operating the drum motor during a whites maintenance phase to cyclically rotate the drum. The default whites maintenance phase liquid level is equal to or less than the default normal maintenance phase liquid level. Methods of operating a laundry machine are also provided.

Disclosed is a dryer operating method that is useful in a 5G environment provided for the Internet of Things. The dryer of the disclosure includes a heating device, a tumbler connected to the exit of the heating device, a fan connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, and a compressor having an entrance connected to the flow line connected to the exit of the fan and an exit connected to the entrance of the heat exchanger. The method of the disclosure includes heating the working fluid using the heating device, reducing the pressure in the tumbler by discharging a portion of the working fluid in a circulation line to outside using the compressor, drying an object to be dried received in the tumbler, and cooling the object to be dried.

A dryer appliance may include a cabinet, a drum, a heater assembly, a temperature sensor, and a controller. The heater assembly may be in upstream fluid communication with a drying chamber. The temperature sensor may be in upstream fluid communication with the drying chamber. The controller may be in operable communication with the heater assembly and the temperature sensor. The controller may be configured to initiate a test cycle. The test cycle may include activating the heater assembly, detecting a first temperature upstream of the drum at a first moment following activating the heater assembly, detecting a second temperature upstream of the drum at a second moment following the first moment, determining a temperature delta as a difference between the second temperature and the first temperature, comparing the temperature delta to a delta threshold, and initiating an alert message based on comparing the temperature delta to the delta threshold.

A dryer includes a dehumidification filter containing a temperature responsive material with an upper critical solution temperature, a fan sending gas through the dehumidification filter, a heater heating the dehumidification filter, and a controller controlling the fan and the heater and switching an operation mode of the fan and the heater between a drying mode and a regeneration mode, wherein, in the drying mode, an object to be dried is dried with the fan sending the gas through the dehumidification filter that is heated by the heater to temperature higher than or equal to the upper critical solution temperature, and in the regeneration mode, the dehumidification filter is regenerated with the fan sending the gas through the dehumidification filter at temperature lower than the upper critical solution temperature.
