  • Patent number: 10208420
    Abstract: An ozone laundry system that injects ozone into the chemical injection system in order to allow the system to inject ozone as other cleaning chemicals are injected into the washer. This allows ozone to be injected through the wash cycle rather than just during the initial fill phase and additional avoids the expense and maintenance of adding ozone recirculation plumping to an ozone laundry system. Accordingly, ozone levels may be maintained at superior levels throughout the wash cycle.

  • Patent number: 10103020
    Abstract: A substrate processing apparatus includes a substrate holding part, a substrate rotating mechanism, a processing liquid supply part for supplying a processing liquid onto the substrate, a cup part for receiving the processing liquid spattering from the substrate being rotated, by its inner peripheral surface, a top plate disposed above the substrate, and a liquid film forming part for forming a rotating liquid film which rotates in the same direction as the substrate does, on the inner peripheral surface of the cup part, by supplying a liquid onto an upper surface of the top plate rotating in the same direction as the substrate rotates, in parallel with a processing of the substrate with the processing liquid. It is possible to prevent droplets caused by collision of the processing liquid spattering from the substrate against the cup part from being deposited on the substrate.

  • Patent number: 10047469
    Abstract: A method of automatically initiating a procedure to adjust dosing of laundry treating chemistry after satisfying a threshold of determined over-sudsing conditions in a laundry treating appliance during a cycle of operation. When an over-sudsing condition is detected, an over-sudsing counter is initialized, and the data is stored in the memory of a laundry treating appliance as an aggregate total. Once a predetermined threshold is satisfied, a predetermined dosage of laundry treating chemistry is reduced and the over-sudsing counter is reset. The over-sudsing counter can also be reset in the event of an operational event such as a replenishment of a bulk treating chemistry, input by a user of a default value, or passing of a temporal reference, wherein the predetermined dosage is reset to a default value.

  • Patent number: 10023989
    Abstract: A laundry treatment apparatus in which as an outer tub vibrates, a piston and a cylinder are relatively moved. When as the outer tub vibrates, the piston and the cylinder move relative to each other and a frictional member provides a frictional force between itself and the other one to attenuate vertical vibration of the outer tub. In particular, the piston and the cylinder are prevented from being separated from each other in the laundry treatment apparatus.
