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 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.

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.

An air filtration system for a laundry apparatus includes an air-lint inlet forming an interior volume configured to fluidically couple to a tumbler of the laundry apparatus and extending to an end portion. The system further includes a lint-collection reservoir coupled to the air-lint inlet configured to hold a liquid at a level, wherein the air-lint inlet extends into the lint-collection reservoir. The system further includes an outlet conduit in fluid connection with the air-lint collection reservoir. The outlet conduit is configured to expel filter air from the air-lint collection reservoir.

A laundry appliance includes a first lint filter operable between a use position and a maintenance position, a second lint filter proximate to the first lint filter, a switch operable between a first condition and a second condition, and a blower. Movement of the first lint filter from the use position to the maintenance position prompts the switch to enter the second condition from the first condition. The blower is operable to deliver process air through the first and second lint filters in the first condition of the switch and is configured to activate to deliver process air through the second lint filter based on the switch entering the second condition.

A device for dryer vent includes a sensor node having a plurality of sensors, a base node that receives data transmission package from sensor node, a robotic device placed inside a robotic device housing. Base node on blockage detection communicates with the robotic device which is capable of autonomous traversal inside dryer vent to clean the dryer vent. A lint basket placed inside the robotic device housing is used by the robotic device to store lint removed from dryer vent during a cleaning cycle. A latch placed inside robotic device housing communicates with base node to allow the robotic device to enter or exit the robotic device housing during the cleaning cycle.
