A method for washing of the present invention comprises: a water supply step of supplying water into a tub; a motor actuating step of actuating the motor for rotating a drum provided inside the tub; and a spray step of spraying water into the drum through a gasket nozzle by actuating a pump for circulating the water inside the tub, when the motor stops.

A dryer vent monitor device includes a temperature sensor coupled to a dryer exhaust pipe to measure a temperature inside the dryer exhaust pipe. A differential air pressure sensor is coupled at an input connection between a dryer and the exhaust pipe and at an output connection between the dryer exhaust pipe and an outdoor vent. The differential air pressure sensor measures a differential air pressure between the input connection and the output connection. A transceiver communicates with a monitoring system registered with the dryer vent monitoring device. The dryer vent monitoring device compares both the temperature and the differential air pressure with a preset threshold, determines that at least one of the temperature and the differential air pressure exceed the preset threshold, and generates an alert signal in response to determining that at least one of the temperature and the differential air pressure exceed the preset threshold.

The present invention relates to a laundry-care appliance (100) having a washing tub (107) and a deodorizing module (109) for dispensing deodorizing substance into the washing tub (107), wherein the deodorizing module (109) is connected to the washing tub (107) and comprises a radial fan (115) for ventilating the washing tub (107), wherein the radial fan (115) is drivable in a first direction of rotation (121) and in a second direction of rotation (123). The deodorizing module (109) is configured to dispense deodorizing substance into the washing tub (107) in a first period of time, wherein the radial fan (115) is drivable in the first direction of rotation (121) in the first period of time in order to distribute the deodorizing substance in the washing tub (107). The radial fen (115) is drivable in the second direction of rotation (123) in a second period of time following the first period of time, in order to remove the deodorizing substance from the washing tub (107) in the second period of time.

Dryer appliances and methods for operating dryer appliances are provided. A method includes flowing internal air from a drum chamber through an outlet assembly of the dryer appliance, and selectively actuating a valve to flow external air to the outlet assembly of the dryer appliance from external to a cabinet of the dryer appliance. The method further includes alternately sensing open flow pressure values of the external air being flowed to the outlet assembly from external to the cabinet when the valve is open and closed flow pressure values of the external air being flowed to the outlet assembly from external to the cabinet when the valve is closed.

The following relates generally to dryer duct safety. In some embodiments, a system may include an airflow sensor configured to measure airflow in a dryer duct. The system may further include one or more processors configured to receive an operation status signal of a dryer, determine an airflow level based upon an airflow signal received from the airflow sensor, and determine that a clog exists in the dryer duct based upon: (i) the airflow level and (ii) the operation status signal. The system may further include a robotic component to clean the dryer duct upon determining a clog exists.

An exhaust system includes a filter; and a fan downstream for the filter whereby activating the fan clears the filter. The exhaust system may form part of a lint collection system that is for attachment to a dryer.

A method for operating a laundry treating appliance having a housing; a treating chamber located within the housing. A duct fluidly coupling the treating chamber to an exterior of the housing with a vent located within the duct. The vent moveable between an open position where a fluid flow passes freely between the treating chamber and the exterior and a closed position where the treating chamber is fluidly isolated from the exterior.

A washing machine of the present invention comprises a casing; a tub disposed inside the casing; a drum rotatably provided inside the tub, for accommodating laundry therein; and a gasket interposed between the casing and the tub, for preventing water in the tub from leaking between the tub and the casing. Wherein the gasket comprises a plurality of gasket nozzles for spraying water into the drum; and a plurality of connectors for supplying water to the respective gasket nozzles. Wherein the gasket nozzle comprises a spray guidance surface for refracting the an advancing direction of the water supplied through the connector so as to spray the water toward inside of the drum; and a plurality of protrusions provided adjacent to an finish end of the spray guidance surface on which the water guided along the spray guidance surface is separated, and arranged along an width direction of the spray guidance surface.

A vented laundry dryer has an air inlet duct, an air outlet duct, a heat recovery system for transferring heat from the air outlet duct to the air inlet duct, and an additional heater. The heat recovery system has an evaporator, a liquefier, a condenser, and a relaxation unit, wherein the liquefier is thermally coupled to the air inlet duct, and the evaporator is thermally coupled to the air outlet duct. A relaxation property of the relaxation unit can be adjusted depending on at least one parameter that is connected to an activity of the additional heater. A method for operating a vented dryer having an additional heater and a heat pump having a relaxation unit, monitoring at least one parameter connected to an activity of the additional heater and changing a relaxation property of the relaxation unit depending on the at least one parameter.

The invention discloses a new embodiment concept and components for drying articles in an energy-efficient and effective way. The embodiment has a stationary drum accommodating a grid with several underneath nozzles at the bottom for blowing compressed hot air into articles and moving them within the space. A magnetron generates microwaves inside the drum for evaporating articles' moisture. A reciprocating compressor vacuums out the hot vapor and compresses it again in a high-pressure three-layer multifunctional tank after passing through a set of moisture separators to be reused by the nozzles in a closed cycle. Several low-maintenance and durable Membrane Dryers are used in parallel as a moisture separator unit before the compressor. Condensed and separated liquid is used in a heat exchanger to warm the makeup air needed for membranes. Nozzles' on/off states, the magnetron and compressor are controlled by a closed-loop digital controller for achieving an optimized drying process.
