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.

A dishwasher includes: a spray module which sprays washing water toward dishes; a sump which supplies washing water to the spray module; a pump which pumps washing water stored in the sump to the spray module; and an air jet generator which receives a part of washing water pumped from the pump to form an air bubble in washing water and discharges the air bubble to the sump, wherein the air jet generator comprises: a decompression portion which decreases a pressure of washing water; an air suction portion which is opened to allow air to flow into the decompression portion; a pressing portion which increases pressure so as to crush the air introduced from the air suction portion; and an air tap which has a plurality of holes configured to crush the air contained in washing water that passed through the pressing portion.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pro-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.

This disclosure proposes a cleaning device for cleaning items to be cleaned. The cleaning device has at least one fluid device for applying at least one cleaning fluid to the items to be cleaned. The cleaning device has at least one electrical load. The cleaning device further has at least one electrical connection for supplying electrical energy to the cleaning device. The cleaning device further has at least one energy store. The cleaning device is designed to receive electrical energy via the electrical connection and to temporarily store said electrical energy in the energy store. The cleaning device is further designed to supply electrical energy from the energy store to the at least one electrical load.

A method and apparatus for operating a food waste recycling appliance includes a food waste recycling container, a condensate reservoir, a first fluid pathway fluidly coupling the food waste recycling chamber and the condensate reservoir, and a fan moving air from the food waste recycling chamber to the condensate reservoir along the first fluid pathway to define a first airflow.

Aspects of the present disclosure provide various apparatus and methods. In some embodiments, an apparatus is provided for mixing a gas with a liquid. The apparatus may include a pipe having two ends. The pipe may provide a main fluid path and may have an interior surface having a first groove. The apparatus may also include a helical vane disposed inside the pipe. The vane may have a first projecting tongue that engages the first groove. The apparatus may also include a gas injection port on the pipe adapted to inject gas into the fluid path upstream of the helical vane. In some embodiments, the helical vane may be a 3D printed component.

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.
