An energy efficient autonomous laundry system includes a plurality of combination washing and drying machines each one of which includes heated and cold side heat exchangers disposed in series within a dedicated closed air loop at each machine, a heat pump providing separate streams of heated and cooled fluid to the heat exchangers, one or more sensors disposed in the closed air loop, and a controller in operative communication with all of these system components. The controller is configured to receive an output signal of one or more air sensors in the closed air loop, analyze the output signal, determine, based on the analysis, whether the at least one air characteristic is within a range of values for at least one of air temperature, air flow, and air humidity, and adjust one or more controls, including controls for adjusting at least one of air temperature, air flow, and air humidity.

A drum for a washing machine for washing and/or spin-drying mattresses, the drum being able to rotate about a substantially horizontal axis and comprising at least one parallelepiped-shaped compartment.

A laundry treating apparatus includes a drum and a lifter disposed on an inner circumferential surface of the drum and configured to rotate with the drum. The lifter includes a lifter frame installed on the inner circumferential surface of the drum and a frame cover coupled to the lifter frame. The lifter frame includes a frame base coupled to the inner circumferential surface, a frame upper plate having a first water flow through-hole, and a frame sidewall that connects the frame upper plate to the frame base and that defines a second water flow through-hole. The frame cover includes a cover upper plate having a water flow discharge hole configured to discharge, into the drum, washing water having passed through at least one of the first water flow through-hole or the second water flow through-hole, and a cover sidewall that extends from the cover upper plate to the frame base.

A combination washer/dryer machine has a cabinet with a tub and drum positioned in the cabinet. The drum is rotatably positioned in the tub. A heater is secured to the tub. The heater includes a duct to provide heated air from the heater. The duct is coupled with the tub to supply heated air to the drum.

A combination washer/dryer machine includes a rotatable drum inside a cabinet. The drum has an external surface. A tub is positioned inside the cabinet. The drum is rotatable in the tub. The tub has an inner surface. A seal contacts the exterior surface of the drum and the inner surface of the tub during drying operation to minimize the bypass of drying air.

A clothing processing device disclosed in the present specification includes: a cabinet; a drum provided inside the cabinet, made of a metal material, and provided to receive a laundry therein; and an induction module which is spaced apart from the circumferential surface of the drum and heats the circumferential surface of the drum through a magnetic field generated when a current is applied to a coil having a wound wire, wherein: the induction module includes a base housing for receiving the coil; the coil includes a first region which is a portion located adjacent to the front of the drum, a third region which is a portion located adjacent to the rear of the drum, and a second region which is a portion positioned between the first region and the third region; and a shortest width of the first region or the third region is formed to be greater than a shortest width of the second region so that the coil having the wire wound on the base housing has different widths.

A drum washing machine includes a tub and a drum rotatably supported in the tub and implements a control method that allows the tub to be easily cleaned. The method of controlling the washing machine includes supplying washing water during a first water supplying step to the interior of the tub while the drum is rotating at a water-supplying RPM; and executing a first wash step following completion of the first water supply step by accelerating the rotation of the drum from the water-supplying RPM to a first-wash RPM so that a circulatory flow is created 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 lifter for a laundry treating apparatus includes a first member mounted at an inner side of a drum; and a second member mounted on the first member and protruded toward an inside of the drum, wherein the first member includes a hook protruded and formed along a circumference of the first member, at least part of which is disposed to cover an inner circumferential surface of the drum when inserted into a fastening hole of the drum and then slid in one direction; and a shield protruded and formed at an inner side of the first member and configured to completely cover the fastening hole when the hook is inserted into the fastening hole and then slid in one direction.
