A home appliance is provided. The home appliance includes a motor configured to execute a predetermined function of the home appliance, and a processor configured to determine an upper limit of noise of the home appliance based on ambient noise information of the home appliance and control a driving speed of the motor to have magnitude of noise of the home appliance equal to or less than the upper limit of the noise.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pre-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.

A liquid distributor for a liquid-transfer system of a conveyor dishwasher has first, second and third connections. The liquid sprayed in at least one final-rinse zone of the conveyor dishwasher can be fed to the liquid distributor via the first connection, wherein some of the liquid fed to the liquid distributor can be discharged, via the second connection, to a line system which can be connected to the second connection, and wherein the rest of the liquid fed to the liquid distributor can be discharged, via the third connection, to at least one line system which can be connected to the third connection. The liquid distributor has an interchangeable aperture component, which defines the fraction of liquid which is fed to the liquid distributor via its first connection and is to be discharged, via the second connection, to the line system which can be connected to the second connection.

A dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

Provided is a method of operating a dishwasher including a heat pump circuit, wherein a condensate collection container is associated with an evaporator of the heat pump circuit. The method may include the steps of pumping a washing liquid from a sump of the dishwasher using a pump device, opening a first valve in a condensate conduit connecting the condensate collection container with a suction conduit of the pump device, pumping a condensate from the condensate collection container using the pump device. A dishwasher may also be provided.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A dishwasher includes a dishwashing container, a lower holder for items to be washed arranged in the dishwashing container, and an upper holder for items to be washed which is arranged in the dishwasher container above the lower holder. A control device executes a dishwashing program from a number of dishwashing programs for washing the items to be washed by actuating a hydraulic facility in such a manner that in a first segment of the dishwashing program a washing liquor having a first washing liquor temperature is only sprayed by a lower spray facility onto the lower holder and in a second segment of the dishwashing program following the first segment washing liquor having a second washing liquor temperature that is lower than the first washing liquor temperature is sprayed by an upper spray facility onto the lower holder and the upper holder.

A method includes actuating a pump at a constant nominal flow-rate to induce liquid flow out of a vessel through an outlet duct. The outlet duct communicates with the vessel with an upper aperture at an intermediate level height, and a lower aperture at a reduced level height. Flow of liquid is detected in the outlet duct. A digital signal assumes an alternate sequence of states when the liquid level is between the intermediate and reduced levels. Each state is an air-indicating state or liquid-indicating state. The presence or absence of air bubbles is detected in the flow of liquid. The digital signal is compared with a reference signal having a predetermined sequence of air-indicating states and liquid-indicating states. Pump actuation duration is modified as a function of a difference between the digital and reference signals. An apparatus is controls the supply of a liquid level in a vessel.

The stationary gasket used in all kinds of dishwashers and similar household appliances, characterized in that; it ensures the sealing not by being compressed but by stretching and ensures sealing in both ways with a single part.

A dishwasher includes a washing system configured as a recirculation loop and a dirt discharge system associated with the washing system. The dirt discharge system is associated with a separator apparatus configured so as to separate at least a portion of the washing liquid required to empty a dirt collection region of the dirt discharge system and discharged together with the dirt particles from the dirt collection region from the dirt particles discharged from the dirt collection region and to return the separated washing liquid back to the water circulation of the dishwasher.
