A laundry processing apparatus include a washing unit provided in an installation space of a cabinet, which corresponds to an upper portion of a heat exchanger and has the installation space therein, to spray washing water to a front surface of an evaporator. The washing unit has a nozzle part provided at the upper portion of the heat exchanger in an inclined direction to guide the washing water toward the heat exchanger and a front guide part provided at an opposite side of the nozzle part while being space apart therefrom, with the front surface of the evaporator that is the heat exchanger interposed between the front guide part, guiding the washing water discharged from the nozzle part toward the front surface of the evaporator.

A clothes dryer comprises an inner drum, an outer drum, an air heating and supplying means and an air duct, and at least two air chambers each in communication with the air duct. The air chambers are respectively arranged corresponding to two sides along which clothes rise or fall as the inner drum rotates, the air chamber at one side starts supplying air and the air chamber at the other side stops supplying air according to a rotation direction of the inner drum, all air chambers are distributed in the order of front and rear of the outer drum in an axial direction, and the rotation direction of the inner drum is controlled according to the distribution of the air chambers, such that air is supplied in different positions corresponding to the front part and the rear part of the inner drum at different clothes drying stages, in order to dry clothes.

A laundry appliance includes a tub having a rear wall. A drum is rotationally operable within the tub. An air flow path extends through an air flow port defined within the rear wall. A lint filter is positioned within the air flow port. A fluid spray system extends through the rear wall and directs a flow of fluid over the air flow port and the lint filter in a direction generally parallel with an inside surface of the rear wall.

A drying machine for drying clothing includes: a housing; a drum configured to receive clothing; a guide apparatus for guiding air in a path through the drum; an air moving apparatus to pull air through the guide apparatus and drum; a heating apparatus for heating air and having on and off conditions; a heat capacitor for storing and releasing heat to air when the heating element is in its off condition and the drum is rotating; power means for components of the drying machine; including at least the drying compartment assembly, rotation means, guide apparatus, air moving apparatus, heating apparatus, and control apparatus; a control apparatus for controlling at least one of the drying compartment assembly, the rotation means, guide apparatus, the air moving apparatus, the heating apparatus, and the power means; and restrictor means for restricting the air flow whereby the drum pressure is lower than ambient air pressure.

A dryer appliance that includes a fire extinguishing system is provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber for receipt of articles for drying. The dryer appliance includes a water inlet valve in fluid communication with a steam nozzle operable to deliver water into the chamber to form mist or steam. The dryer appliance also includes an extinguisher nozzle in fluid communication with the chamber of the drum and with the water inlet valve. Upon detection of a fire, water is provided to the extinguisher nozzle and the extinguisher nozzle directs a stream of water into the chamber to extinguish the detected fire.

The invention relates to a condenser tumble dryer with a drum for articles to be dried, a drive motor for the drum, a process air duct, a process air blower, a heating and cooling system for the process air, a temperature sensor and a control device. The temperature sensor is an infrared telescope and is arranged to simultaneously measure heat radiation from at least two components of the condenser tumble dryer which are to be monitored. The invention also relates to a method for operating a condenser tumble dryer of said type.

A dryer appliance includes a cabinet defining an interior, and a drum positioned within the interior. The drum defines a chamber for receipt of articles for drying, and includes a cylinder and a rear wall. The cylinder is rotatable relative to the rear wall. The dryer appliance further includes a heater configured to provide heat to the chamber, the heater comprising a heating element mounted to the rear wall.

A laundry appliance uses a determination of a frequency of compressor temperature response, refrigerant mass flow rate, or both to determine accumulation of lint in a filter. Based on the determination, various corrective actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof.
