Sensor units that includes a power source, a communication interface, and a sensor coupled to the power source and the communication interface. The sensor is calibrated to connect the power source to the communication interface upon an occurrence of a condition in an appliance. The sensor, thereby, permits the communication interface to transmit data indicating the condition to a computing device. Methods, systems, and apparatus, for monitoring such sensor units.

A laundry appliance includes a blower that delivers process air through an airflow path. A rotating drum defines a processing chamber. The processing chamber is part of the airflow path. A steam generating system disposes steam into the processing chamber. A plurality of fluid nozzles direct the steam into the processing chamber according to an operating pattern. The plurality of fluid nozzles include a first nozzle that is positioned within an upper portion of the processing chamber and a second nozzle that is positioned in a lower portion of the processing chamber.

A drying air duct, a clothing treatment device and a method for cleaning a drying air duct are provided. The drying air duct includes a condensing section air duct, a heating section air duct and a fan; the fan is provided at a connection position of the condensing section air duct and the heating section air duct, a cleaning device is provided in the condensing section air duct, the cleaning device is provided at an end of the condensing section air duct adjacent to the fan and is capable of cleaning a side of the condensing section air duct away from the fan. The drying air duct can effectively clean the pipe sudden expansion area of the condensing section air duct, preventing the accumulation of soft flocks in the condensing section air duct.

The present disclosure provides a drying device and a method for controlling same. The drying device of the present disclosure may comprise: a drum; a driving unit; a heater to heat air supplied to the interior of the drum; a communication interface; and a processor that: when a user command for a drying cycle is received, controls the driving unit so as to rotate the drum in a preset pattern; when data generated on a basis of motion of a sensing device is received through the communication interface from at least one sensing device, identifies a sensing device that has a motion corresponding to the preset pattern among the at least one sensing device; and controls the driving unit and the heater so as to perform a drying cycle on the basis of humidity data received through the communication interface from the identified sensing device.

A dryer appliance and sensor assembly are provided. The sensor assembly may include a sensor housing, an appliance sensor, a wireless transmission tag, and a generator. A magnet rail is statically affixed to a cabinet. The sensor housing may extend within a drum and define a compartment proximate a space for the receipt of clothes. The generator is positioned within the compartment. The drum positions the generator in operable communication with the magnet rail. The appliance sensor may be positioned on the sensor housing. The wireless transmission tag may be positioned within the compartment. The wireless transmission tag may be in communication with the appliance sensor. The wireless tag reader may be in operable communication with the wireless transmission tag.

A delivery device for delivering a detergent independently of a change in a viscidity of a detergent and a method of controlling the same are provided. The delivery device includes a detergent storage; a pump configured to inject the detergent into a dissolving container a motor configured to drive the pump; a delivery container communicated with the detergent storage via a first one-way valve; the dissolving container communicated with the delivery container via a second one-way valve, the first and second one-way valves having opposite liquid conducting directions; a piston disposed in the delivery container; a crank-connecting rod mechanism constituted by the delivery container, the piston, a piston rod and a crankshaft; a contact switch; a cam disposed on a main journal of the crankshaft, a point of an outer contour of the cam triggering the contact switch to turn on and off once when the crankshaft makes one revolution.

Provided are a clothes dryer using far-infrared heating and a clothes-drying control method thereof. The clothes dryer using far-infrared heating includes a clothes-drying drum, and further includes at least one far-infrared heater, a humidity sensor for detecting exhaust humidity of the clothes-drying drum, a relay and a controller having an output end connected with the relay; where all the far-infrared heaters are connected with a power supply through the relay; a first temperature sensor is mounted inside one of the far-infrared heaters; the first temperature sensor and the humidity sensor are connected with an input end of the controller; and the controller controls on and off of the relay according to a received temperature signal or humidity signal. A control system described above simplifies a circuit, and also saves cost.

A dryer monitoring system receives dryer information from one or more sensors concerning operation of one or more dryers, such as clothes dryers. For example, the dryer monitoring system may receive temperature and/or humidity information from one or more dryers. The dryer monitor analyzes the dryer data to determine whether textiles in the dryer are dry. The dryer monitor may analyze one or more states and/or one or more indicators (patterns in the dryer data) during the dryness determination.
