A clothes dryer comprising: a cabinet; a control panel including a power button and a display; a drum rotatable inside the cabinet; a filter to filter air discharged from the drum; a filter sensor to detect a mounting state of the filter and output a detection signal based on the mounting state of the filter detected; a memory to record a change in the mounted state of the filter as an event based on the mounting state of the filter detected by the filter sensor; and a processor to communicatively connect to the control panel, the filter sensor, the memory, and to control the display so that the display displays a notification related to the management of the filter based whether the event due to the change in the mounting state of the filter is recorded in the memory.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

A method evaluates a fiber product and includes washing at least one fiber product by a washing machine and washing conditions defined in ISO 6330 (2012), collecting fiber fragments discharged from a wastewater outlet of the washing machine by a filter with a sieve opening of 5 to 20 μm, and measuring a weight of the fiber fragments.

A laundry appliance includes a wash tub disposed within a cabinet. A rotating drum is disposed within the wash tub. A drain system directs a fluid from the wash tub to a fluid pump. A trap is disposed within a tub drain of the wash tub. The trap includes an elongated body having a plurality of fingers that extend across an aperture defined within the elongated body. The plurality of fingers are configured to permit passage of particulate material and prevent passage of foreign objects through the elongated body.

A washing machine including a drainage pump to discharge water from a tub of the washing machine through a drainage passage, a first filter to which the water flows due to the drainage pump and provided along the drainage passage to filter out foreign matter equal to or greater than predetermined size, and a second filter to which the water flows from the first filter and provided along the drainage passage and to filter out foreign matter smaller than the predetermined size, wherein the drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.

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 that circulates heated air through the chamber. A controller is configured to receive a command to initiate an appliance travel cycle and implement a responsive action to prepare the dryer appliance for travel. The responsive action may be the automated adjustment of one or more operating parameters of the dryer appliance, such as performing a load sensing procedure, drying the chamber, closing the water supply valves, etc. In addition, the responsive action may include providing a user instruction to prepare the dryer appliance, e.g., by cleaning the lint filter, emptying the condensate collection tank, removing hoses and cables, addressing any error codes, etc.

The present invention provides a laundry treating apparatus including a drain pump having a motor, an inverter unit to transfer power to the motor, and a control unit to control the inverter unit to operate the drain pump, wherein the control unit sets an operation mode of the drain pump based on a current flowing in a part of the inverter unit, and controls the inverter unit based on the set operation mode.

A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure and a laundry treatment machine including the same include: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and to output the converted AC voltage to a drain motor; and a controller to control the motor to, when a drain channel in a drain pump is clogged, be temporarily stopped in a period during which a speed of the motor increases and then to repeatedly rotate and stop in a first direction the same as a start-up direction, and to repeatedly rotate and stop in a second direction opposite to the first direction when the drain channel is clogged even after the motor repeatedly rotates and stops in the first direction. Accordingly, when impurities are introduced into the drain pump, the impurities can be removed in a simple manner.

Provided herein are an appliance and method for washing and rinsing goods. The appliance may include a circulation pump, a sensing arrangement arranged to measure an indication of circulation pump pressure or process water flow rate through the circulation pump, and a controller arranged to control operating speed of the circulation pump. The controller may be further arranged to detect that the indicated circulation pump pressure or process water flow rate through the circulation pump is insufficient, and gradually reduce operating speed of the circulation pump until the circulation pump pressure or the process water flow rate through the circulation pump is at a sufficient operational level.
