Автор: Andrew M. Jensen, Bryan J. Henneman, Jason A. Kahlhamer, Jeff P. Ellingson
Принадлежит: ECOLAB USA INC

A dish machine includes optimized dish machine operating parameters that may result in increased energy efficiency and reduced utility costs. The operating parameters may include one or more of a wash water temperature, a rinse water temperature, and/or a rinse flow rate. In some examples, the optimized parameters may include a wash water temperature in the range of 160° F. to 164.5° F., a rinse water temperature in the range of 182° F. and 211° F., and a rinse flow rate in the range of 0.4 gal/rack and of 0.66 gal/rack.

Dishwasher and a control method therefor

Номер: US20120037186A1
Автор: Gyeong Ho Moon, Nung Seo Park
Принадлежит: LG ELECTRONICS INC

In the dishwasher and the control method therefor of the present invention, the turbidity of washing water is measured and, if it is decided that the level of dirtiness of the tableware is low, then the time over which a heater operates during the washing routine is reduced and, instead, the time over which the heater operates during the rinsing routine is increased. This is advantageous in that it can improve the performance of the drying which is carried out after the rinsing routine. Further, if it is decided that the level of dirtiness of the tableware is high, then the time over which the heater operates during the washing routine is increased and the time over which the heater operates during the rinsing routine is reduced. This is advantageous in that the washing performance can be improved while the overall heater operating time can be maintained.

Rapid heat system for a multi-tub dishwasher

Номер: US20140026929A1
Автор: Kristen K. Hedstrom, Mark E. Palm, Rodney M. Welch
Принадлежит: Whirlpool Corp

A dishwasher includes a first washing chamber and a second washing chamber capable of performing a washing operation separately and/or concurrently. Each washing chamber includes a wash pump, a drain pump and a heating unit that are operatively connected to a controller. When initiating a washing fluid in one washing chamber, the controller determines if the other washing chamber is active. If the other washing chamber is active, the heating unit for the one washing chamber is operated at a low power level. However, if the other washing chamber is inactive, the one washing chamber is operated at a high power level to rapidly heat the washing fluid and thus shorten the duration of the washing operation.

A turbidity sensor assembly for a dishwasher appliance is provided. The turbidity sensor assembly measures the turbidity of wash fluid in a manner similar to conventional turbidity sensors, but also includes an integral water level indicator. The water level indicator is an opaque buoyant ball that rises and falls with the water level to provide a water level indication that can be used to shut off the drain pump when the sump is empty. More specifically, when the water level drops below a predetermined level, the opaque ball blocks the transmission of light between the emitter and receiver of the turbidity sensor, thus indicating that the sump is almost empty. As a result, the pump operating during a drain cycle need only operate long enough to drain the sump, and this may be achieved without an additional measuring device or complicated control system. 1. A dishwasher appliance defining a vertical direction , a lateral direction , and a transverse direction , the dishwasher appliance comprising:a wash chamber for receipt of articles for washing;a sump positioned adjacent a bottom of the wash chamber, the sump configured for collecting wash fluid;a pump in fluid communication with the sump, the pump being configured for discharging the wash fluid from the dishwasher appliance during a drain cycle; and a housing defining a channel in fluid communication with the wash fluid;', 'an emitter and a receiver positioned within the housing on opposite sides of the channel;', 'a buoyant object positioned within the channel; and', 'a retention device configured to enable the buoyant object to move along with the level of the wash fluid within the channel along the vertical direction between a raised position and a lowered position., 'a turbidity sensor assembly configured for measuring a turbidity and a level of wash fluid in the sump, the turbidity sensor assembly comprising2.

VARIABLE POSITION HYDRAULICALLY ACTUATED DIVERTER FOR AN APPLIANCE

Номер: US20170027406A1
Автор: Curtis Craig, Durham Kyle Edward, Ross Christopher Brandon
Принадлежит:

A passive diverter is provided that does not require a dedicated motor to switch between multiple outlet ports. The diverter uses the forces provided by a flow of fluid from a pump to switch between different outlet ports and supply one or more spray assemblies or other fluid-using elements. A separate motor to power the diverter is not required, which allows a savings in costs and space. In addition, a secondary set of ramps may provide a manner in which to “zero” the angular position of the diverter, i.e., place the diverter in a known, home position. This can reduce the additional cost, weight, and complexity of including additional sensors to determine the angular position of the diverter. 1. A dishwasher appliance , comprising:a wash chamber for receipt of articles for washing;a pump for providing fluid flow for cleaning the articles; a plurality of outlet ports for providing fluid to the wash chamber;', 'a housing defining a chamber, the chamber fluidly connecting a fluid inlet and a fluid outlet such that a fluid may flow into the chamber through the fluid inlet and out of the chamber through the fluid outlet to one or more of the outlet ports, the housing also defining a cylindrically-shaped well;', 'a first ramped element positioned within a distal end of the well;', a disk defining a plurality of apertures for selectively controlling fluid flow from the fluid outlet to one or more of the outlet ports, the apertures being spaced apart along a circumferential direction;', 'a cylindrically-shaped shaft connected to the disk and extending along the axial direction, the shaft slidably received within the well of the housing, the shaft defining an interior channel;', 'a plurality of cams positioned on the cylindrical shaft near the disk and projecting radially inward from the cylindrical shaft into the interior channel;', 'a second ramped element positioned near a distal end of the shaft;, 'a valve positioned within the fluid outlet, rotatable about an axis, and ...
