The present disclosure relates to a method for controlling a laundry dryer, the method comprising: a steam supplying step for supplying steam to a heat exchange unit; a cleaning step for controlling a cleaning unit after the steam supplying step, and thereby spraying cleaning water to the heat exchange unit according to preset spraying criteria; and a drying step for drying the heat exchange unit after the cleaning step. The present invention has the effect of eliminating and sterilizing foreign substances, microorganisms, and the like present in the heat exchange unit.

A laundry treating appliance includes a cabinet defining an interior. A drum is located within the interior and defines a treating chamber. The laundry treating appliance includes a recirculation circuit including a recirculation pump having an inlet and an outlet. The laundry treating appliance further includes a bulk treating chemistry dispenser. A method for rinsing or cleaning the bulk treating chemistry dispenser can be included.

The present disclosure provides a method of controlling a laundry treating apparatus including a tub in which a drum accommodating clothing is rotatably disposed, a heat exchanger configured to perform heat exchange between air discharged from the tub and a refrigerant in a circulation flow path through which the air circulates, a filter configured to filter the air, a first cleaning mechanism configured to apply cleaning water to any one of the filter and the heat exchanger, and a second cleaning mechanism configured to apply the cleaning water to the other of the filter and the heat exchanger. The method includes measuring a flow rate while supplying water into the tub, and controlling, based on the flow rate, a first flow path control valve for regulating water supply to the first cleaning mechanism and a second flow path control valve for regulating water supply to the second cleaning mechanism.

A drum washing machine implements a control method, allowing a tub of the drum washing machine to be easily cleaned. The method includes supplying washing water during a first water supplying step to the interior of the tub while a drum rotatably supported in the tub rotates at a water-supplying RPM. A first wash step is executed following completion of the first water supplying step, and includes accelerating rotation of the drum from the water-supplying RPM to a first-wash RPM to that create a circulatory flow in which the washing water falls from the top of opposite ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum. A wash draining step is started during the first wash step, and includes turning on the drain pump and controlling the amount of the washing water in the tub.

A laundry appliance includes a drum rotatably mounted within a cabinet and defining a chamber configured for receiving a load of clothes, a door pivotally mounted to the cabinet for providing selective access to the chamber, and a user interface for controlling operation of the laundry appliance. A controller is configured to monitor the number of wash cycles that have occurred in the laundry appliance since the last self-clean cycle. Once the laundry appliance reaches a predetermined number of wash cycles without an intervening self-clean cycle, an automatic self-clean cycle is initiated upon the next selection of a drying cycle by the user, wherein the drying cycle provides an indication that the chamber is empty of article of laundry and that the user has no further immediate washing needs. In these circumstances, the controller is configured to reconfigure the selected drying cycle into a combination cycle including a self-clean cycle which is automatically followed by the desired drying cycle.

A laundry appliance includes a basket rotatably mounted within a cabinet and defining a chamber configured for receiving a load of clothes, a door pivotally mounted to the cabinet for providing selective access to the chamber, and a camera assembly mounted within the cabinet in view of the chamber. A controller is configured to initiate an automatic self-clean cycle, the method comprising determining that the door is closed, obtaining one or more images of the chamber using the camera assembly, determining that there is no load in the chamber based at least in part on the one or more images, determining that a self-clean condition is satisfied, and commencing the self-clean cycle.
