The first damper is configured to control an airflow from inside the chamber to outside the chamber. The second damper is configured to control the airflow into the chamber from the outside. The heat exchanger is provided with a compressor and configured to exchange heat with air in the chamber. The at least one blower fan is configured to generate the airflow. The sensor portion is configured to obtain a temperature and humidity inside and outside of the chamber. The controller is configured to start a drying cycle, control the first and second damper to be opened or closed, and control the heat exchanger and the at least one blower fan by comparing the internal humidity with the external humidity.

An appliance for drying laundry has an appliance housing, at least one open drying air duct situated inside the appliance housing, for sucking in ambient air during a drying process, and at least one heat pump, which is situated inside the appliance housing and is thermally coupled to the drying air duct. To reduce the energy consumption of such an appliance, the drying air duct has at least one air intake opening, which is situated inside the appliance housing and is situated in a section of the drying air duct upstream of a condenser of the heat pump in relation to an air mass flow through the drying air duct prevailing during the drying process.

A disclosed home appliance system comprises: a washer for washing clothes; a dryer for drying the clothes; an external server for communicating with the washer and the dryer; and a mobile device for controlling the washer and the dryer through the external server, wherein the mobile device can: acquire energy peak time information including time-specific energy billing information from the external server; display a first user interface for receiving the selection of a first interworking course of sequentially operating the washer and the dryer; determine a first cycle time of the first interworking course including a first washing time of the washer and a first drying time of the dryer, the first cycle time being required in order to perform the first interworking course; display a second user interface for receiving the selection of whether to perform the first interworking course on the basis of the energy peak time information and the first operation time; and transmit first interworking course information to the external server in response to receiving the selection of performing the first interworking course.

A wireless sensing device disposed a drum along with laundry to measure humidity in the drum, thereby increasing accuracy in estimation of a degree of dryness, a dryer for determining a degree of dryness of the laundry using the wireless sensing device, and a method of controlling the dryer. The wireless sensing device includes a sensing module including a humidity sensor for measuring humidity in a drum of a dryer into which the wireless sensing module is thrown; a sensor communication module transmitting or receiving data with a main communication module of the dryer through wireless communication; a sensor controller configured to control the sensor communication module to transmit a humidity value corresponding to an output of the sensing module to the main communication module; and a sensor power supplier supplying power to the sensing module, the sensor communication module, and the sensor controller.

A control method of a dual-drum washing machine, comprising the following steps: step S1: before a first washing drum performing heating; step S2: determining whether a second washing drum is heating; step S3: if the determination result is yes, determining whether the remaining heating time of the second washing drum is more than T.sub.0; and step S4: if the determination result is yes, performing an alternate heating procedure in which the first washing drum and the second washing drum heat alternately, and if the determination result is no, performing a sequential heating procedure in which the second washing drum heats before the first washing drum, wherein T.sub.0 is a time value, set through a system, for determining whether heating of the second washing drum is coming to an end.

A washing machine comprises a first washing drum with a first heater and a second washing drum with a second heater. Before the first washing drum performs a heating procedure, it is necessary to determine whether the second washing drum is performing the heating procedure; if not, the first washing drum performs the heating procedure; if yes, it is necessary to determine whether the remaining heating time of the second washing drum is less than a set value, T min; if yes, the first washing drum pauses the heating procedure; when the second washing drum finishes performing the heating procedure, the first washing drum then performs the heating procedure; if not, remaining heating time of the first washing drum and that of the second washing drum are determined, whichever drum having the shorter remaining heating time performs the heating procedure first, while the other drum performs the heating procedure second.

A method of drying laundry in a laundry treating appliance having a treating chamber in which the laundry is received for drying comprises moving the treating chamber to redistribute the laundry, supplying air to the treating chamber to define a supply air flow, exhausting the supplied air from the treating chamber to define an exhaust air flow, actuating a heater at full output to heat the air supplied to the treating chamber, turning the heater off, and maintaining a maximum evaporation rate for a duration of time by operating the heater.

A method of operating a dryer appliance includes determining a remaining moisture content of a load of articles to be dried in the dryer appliance and estimating an energy requirement for drying the load of articles based on the determined remaining moisture content of the load of articles. The method also includes activating a heating system of the dryer appliance during a dry cycle of the dryer appliance while tracking an energy output of the heating system during the dry cycle. The method further includes comparing the tracked energy output to the estimated energy requirement. When the tracked energy output is greater than a predetermined threshold percentage of the estimated energy requirement, a user notification is provided.
