The invention relates to preventing microplastics from entering the environment. The invention is directed to filtering and compacting microplastics from any effluent, but in particular to filtering and compacting microfibers from the wastewater of washing machines and other appliances. However, the invention may also be applied in any industry where microparticles are generated, e.g. the industrial manufacture of textiles, or in treating roadside runoff, or where microparticles are handled, e.g. in Waste Water Treatment Plants. The invention is a compactor for automatically extracting and compressing microplastics from waste effluent, the compactor comprising; a chamber with an inlet; at least one plate within the chamber moveable between a non-compressing position and a compressing position, and a drive unit for driving the at least one plate; and a discharge outlet arranged to allow the automatic discharge of compressed microplastics.

A laundry treating apparatus is disclosed. The laundry treating apparatus includes a first treating apparatus, a second treating apparatus, and a control panel disposed signally connected to the first treating apparatus and the second treating apparatus, and the first treating apparatus includes a lower frame disposed rearward of the control panel and coupled to the control panel to fix the control panel.

The present invention discloses a laundry box, comprising a laundry box body, a seal cover and a drain fence, wherein laundry box water inlets and a laundry box drain outlet are provided at the bottom of the laundry box body, a decontamination conductor plate is provided in the middle thereof, a clothes placing port is provided at the top of the laundry box body, and the seal cover is hinged at the clothes placing port; and the drain fence is detachably mounted inside the laundry box body and is located at the side end close to the drain outlet. The present invention further discloses a machine for separately washing clothes designed to be used in conjunction with the laundry box, comprising a housing, a main machine, a cover plate and at least two laundry boxes.

A control method of a washing machine includes performing a first drum operation of supplying water by a first set amount together with a detergent into the tub and rotating the drum at a first drum rotation speed, while water is supplied performing a pump speed-change operation of accelerating the pump from a first pump rotation speed to a second pump rotation speed and then decelerating to the first pump rotation speed at least once during the first drum operation and performing a second drum operation of operating a heater to heat the water in the tub in a state in which the first set amount of water is supplied into the tub, rotating the drum at a second drum rotation speed during the operation of the heater, and performing a pump constant-speed operation of operating the pump at a third pump rotation speed during the second drum operation.

A system (10) for washing items (12) with purified water alone, comprising a washing machine (11), a water purification apparatus (19), and a reservoir (20) for storing purified water, wherein the water purification apparatus (19) comprises a reverse osmosis device (26) and first and second deionizing materials. The washing machine (11) comprises a container (13) for receiving the items (12) to be washed, and said container (13) is arranged with an inlet connected to the reservoir (20), so that the items (12) are washable inside the container (13) with the purified water. The system (10) further comprises a tank (24) for collecting used water from the container (13), wherein an inlet of the tank (24) is connected to an outlet of the container (13). The system (10) also comprises a sediment filter (28) for filtering off particulate solids from the used water, wherein the sediment filter (28) is arranged between the tank (24) and the water purification apparatus (19).

A washing machine includes a first washing tub, and a second washing tub detachably coupled to the first washing tub. The second washing tub includes a container containing laundry, a lower cover coupled to a top of the container and having an inlet configured to receive a water stream moving upwards in the container when the first washing tub rotates, and an upper cover coupled to a top of the lower cover and having an opening for putting the laundry into the container. A flow path is provided between the lower cover and the upper cover to discharge the water stream introduced through the inlet to an outside of the second washing tub. A slide lock is provided on the upper cover, movable between a binding position and an unbinding position, bound to the lower cover in the binding position, and separated from the lower cover in the unbinding position.

The present invention relates to an apparatus for treating laundry, including a cabinet having an entrance for inserting laundry and a door opening and closing the entrance, a tub positioned in the cabinet and having an opening for allowing the laundry to pass through, a drum rotatably positioned in the tub to receive the laundry, a vibration insulating part maintaining a watertight seal by connecting the entrance and the opening, a balance weight positioned in a front side of the tub to increase a weight of the tub, and an annular passage part extending between the vibration insulating part and the balance weight, the annular passage part fixedly supported by the balance weight, the annular passage part having a plurality of nozzles spraying wash water into the drum through the vibration insulating part.

A pedestal assembly for a laundry appliance configured to operably connect to a water supply and drain of the laundry appliance arranged above the pedestal, the pedestal may include a cabinet defining a cavity configured to receive items to be laundered; and a shoe holder having at least one shaft configured to maintain at least one shoe thereon, wherein the shoe holder is configured to rotate within the cavity during a pedestal wash cycle and the shoe holder is configured to maintain a fixed position within the cavity for storage when the pedestal is not operating in a wash cycle.

A washing machine includes a tub containing water, a drum disposed rotatably in the tub, the drum receiving laundry and a detergent supply device supplying detergent to the tub, wherein the detergent supply device comprises a plurality of cartridges respectively containing detergent, a pump sucking detergent contained in the plurality of cartridges and a passage switching valve selectively allowing the pump to be fluidly communicated with one of the plurality of cartridges.
