A dishwasher including a washing tub having a bottom plate having an opening, a nozzle having a spraying hole configured to spray water, the nozzle passing through the opening, and a sealing member configured to seal the opening. The bottom plate includes a base portion on which the nozzle is installed, and a protruding portion extending downward from the base portion to form the opening, the nozzle includes a support portion on the base portion, and a nozzle side portion facing the protruding portion. A part of the support portion contacts the base portion and another part of the support portion is spaced apart from the base portion according to an inclination of the base portion, where the sealing member is disposed between the protruding portion and the nozzle side portion. The spraying trajectory of the water can thus be kept constant despite the inclination deviation of the base portion.

A cleaning product including a spray dispenser and a cleaning composition suitable for spraying and foaming, the composition housed in the spray dispenser and includes: i) from about 5 to about 15% by weight of the composition of a surfactant system; and ii) a specific glycol ether solvent, the surfactant system and the glycol ether solvent are in a weight ratio of from about 5:1 to about 1:1.

A method for applying a treatment agent to a substrate, wherein the treatment agent is bound to a solid polymeric particle at a first pH, and wherein the substrate is contacted with the solid polymeric treatment particles under conditions such that the treatment agent is released from the solid polymeric treatment particles.

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.

The present invention relates to a dishwasher for washing the dishes and the cooking utensils by spraying washing water, and a control method thereof. The control method of a dishwasher according to an embodiment of the present invention includes: a water supply step of opening a water supply valve to supply washing water to the sump; and a variable spray step of spraying the washing water by at least one of the plurality of spray arms by changing the number of revolutions of the washing pump stepwise, so that the washing water can be sprayed evenly.

A system comprises a support, typically part of dishwashing machine or clothes washing machine, having a plurality of piezoelectric transducers. Each transducer can have a cylindrical housing with a water inlet along a side surface of the housing. The transducers can also comprise a lens and a piezoelectric material with electrodes configured to couple to a power supply.

The present invention relates to a dishwasher for washing the dishes or the cooking utensils by spraying washing water and steam and a controlling method therefor. The method of controlling a dishwasher includes: a steam supply step of supplying washing water to the sump from an external water source; and a steam generation step of maintaining a water level of the washing water existing inside the washing pump at a certain water level or higher and heating the washing water.

A dishwasher provided that may include a washing chamber, a rack adapted to accommodate items to be washed by washing liquid within the washing chamber, an arm, and an arm moving arrangement arranged to move the arm within the washing chamber. The arm may include at least one washing liquid removing element arranged to touch at least one of the rack and washing liquid at the rack upon movement of the arm to remove the washing liquid from the rack. The embodiments herein also relate to method for removing washing liquid from a rack of a dishwasher.

Method and apparatus for treating dishware, in which the method comprises the steps of providing a treatment composition comprising a photoactive component, contacting in an appliance the treatment composition with the dishware, and irradiating the treatment composition with visible light. The step of irradiating the treatment composition with visible light is performed with a source of light that is tool free insertable into and removable from the appliance.
