A laundry treating apparatus is disclosed. The laundry treating apparatus includes a cabinet configured to define a receiving space for receiving laundry, the cabinet having an open surface, a door hingedly provided at the cabinet for opening and closing the open surface of the cabinet, a laundry support unit provided in the receiving space for supporting laundry, and a machinery compartment provided in the cabinet for defining a space that is separate from the receiving space, the machinery compartment being provided therein with an air supply unit for dehumidifying or heating air in the receiving space and supplying the dehumidified or heated air into the receiving space. The air supply unit dehumidifies air in a room that communicates with the receiving space in the state in which the door is open.

Provided is a dryer and a method of controlling the same that may determine whether drying is complete based on a temperature difference between a temperature of air discharged to a drum and a temperature of air flowing in from the drum. According to various embodiments, the dryer includes a drum; a heat pump; a duct configured to accommodate an evaporator and a condenser of the heat pump, heat air flowing in from the drum and discharge the air to the drum; a first temperature sensor configured to measure a temperature of the air discharged to the drum; a second temperature sensor configured to measure a temperature of the air flowing in from the drum; and a controller configured to determine that drying is complete, based on maintaining a difference value between the temperature of the air discharged and the temperature of the air flowing in below a preset value.

A method of operating a laundry appliance in a drying cycle includes motivating a flow of process air from a drum of the laundry appliance across an evaporator of a sealed system. Refrigerant in the evaporator of the sealed system absorbs heat from the flow of process air and the refrigerant circulates through the sealed system. The method also includes receiving, by a controller of the laundry appliance, an input indicative of a characteristic of the sealed system. The method further includes determining, by the controller, a dryness level of articles in the drum of the laundry appliance based on the received input indicative of the characteristic of the sealed system.

A laundry treating apparatus is disclosed. The laundry treating apparatus includes a cabinet configured to define a receiving space for receiving laundry, the cabinet having an open surface, a door hingedly provided at the cabinet for opening and closing the open surface of the cabinet, a laundry support unit provided in the receiving space for supporting laundry, and a machinery compartment provided in the cabinet for defining a space that is separate from the receiving space, the machinery compartment being provided therein with an air supply unit for dehumidifying or heating air in the receiving space and supplying the dehumidified or heated air into the receiving space. The air supply unit dehumidifies air in a room that communicates with the receiving space in the state in which the door is open.

A method for controlling a laundry treating apparatus includes an air supplying step of supplying heated air to the drum through the heat exchange part and a first motion executing step executed while the air supplying step is in progress. The first motion executing step alternately executes a first acceleration mode of rotating the drum at an rpm inducing a centrifugal force equal to or greater than 1G along one of a clockwise direction and a counterclockwise direction and a first deceleration mode of rotating the drum at an rpm inducing a centrifugal force smaller than 1G in a direction equal to a rotational direction set for the first acceleration mode.

A dryer appliance and a method of operating the same are provided. In one aspect, the dryer appliance includes a drum rotatably mounted within a cabinet. The drum defines a chamber that is in fluid communication with a conditioning system of the dryer appliance. The conditioning system heats air circulating therethrough and removes water from the process air. A collection tank collects the water and a drain pump removes water from the collection tank intermittently when the water reaches a predetermined level. The frequency at which the drain pump removes water from the collection tank is utilized to determine the moisture extraction rate indicative of the rate at which moisture is removed from the clothes. The moisture extraction rate is utilized to control the mass flow rate of refrigerant in a heat pump sealed system or the process air flow rate through the closed loop air circuit.

Disclosed herein is a heat pump type dryer for reducing the manufacturing cost thereof and maintaining an appropriate quantity of radiation by auxiliary heat exchanger. The clothes dryer D includes housing 1; drum portion 2 installed in the housing 1 and configured to accommodate clothes; a circulation ventilation path 3 configured to pass through the drum portion 2; a heat pump apparatus 5 having a compressor 52, a condenser 53, a throttling device 54, and an evaporator 51, connected to form a flow path through which refrigerant circulates; an auxiliary heat exchanger 55 installed outside the ventilation path, and connected in series to a flow path in the condenser 53 or in parallel to the condenser 53; and a cooling apparatus 6 configured to cool the auxiliary heat exchanger 55.

A laundry treatment apparatus includes a cabinet, a condensed water collector that is disposed in the cabinet and defines a collection space configured to receive condensed water therein, a discharge pump assembly disposed at the condensed water collector and configured to pump the condensed water from the condensed water collector, a water discharge container configured to receive the condensed water collector pumped from the condensed water collector, and a sterilization module configured to sterilize the condensed water in the condensed water collector.

Disclosed is a multifunctional storage system including a machine chamber and a compartment, in which clothes are received, the multifunctional storage system including: a heat pump unit located in the machine chamber and including an evaporator, a condenser, a compressor, and a pressure controller; a moisture supply unit coupled to the heat pump unit and including a humidification filter; and a fan unit configured to circulate air in the machine chamber from the evaporator toward the condenser, wherein the moisture supply unit is coupled to a front end of the evaporator with reference to a circulation direction of the air, and wherein moisture is supplied to the humidification filter according to a preset condition, and loads of the evaporator and the condenser are increased as the moisture is supplied to the air when the air passes through the humidification filter.

A method controls a laundry treatment apparatus that includes a drum in which a target object to be dried is put, a drum motor to drive the drum, an air duct to guide air into the drum, a heat pump provided in the air duct to dehumidify and heat the air, a blower fan to move the air of the air duct, and a blower motor to drive the blower fan. The method includes a drum driving step for repeatedly driving the drum by accelerating and decelerating the drum, a steam supply step for supplying or stopping steam for a predetermined time during execution of the drum driving step, and an air supply step for circulating internal air of the drum during execution of the drum driving step. The circulation of the internal air of the drum is stopped during execution of the steam supply step.
