Harmony Washer HydroWash System

With typical top loading washers, an agitator provides mechanical action to loosen dirt. The Harmony Washer Hydro Wash System increases the time, water volume and temperature, and detergent concentration to clean fabrics using chemical action.The HydroWash system uses a patened Infusor and a stainless steel wash basket to provide great clothes care. The Infusor and the basket can lock and function together or unlock to work alone. HydroWash action is very different from conventional agitation. HydroWash gets great wash performance that's gentler by moving concentrated detergent through fabrics.The wash system encompasses:

Load Sensing with Adaptive Water Fill
Basket Wash
Centrifusion
Infusor Wash
Conditioning Spin
Cyclone Spin
Spray Rinse
Final Rinse

The HydroWash system uses Load Sensing to determine load size. The Infusor alone rotates (or oscillates) back and forth to "measure" resistance on it's surface. This is called Dry Loading Sensing. The resistance determines how much water is added to the wash basket.Wash water levels are optimized even further by invoking a second load sensing called Wet Load Sensing. As with dry load sensing, the Infusor alone rotates back and forth under the wet fabrics. If wet load sensing detects more resistance than expected, additional water is added to the basket.Load sensing makes possible Adaptive Water Fill. Harmony auto-fills with just the right amount of water needed for great wash performance. This fill information is remembered for the final rinse that completes the wash cycle. Adaptive water levels are matched to load size using one-third less water than typical top load washers.Harmony will use as little as 19 gallons of water for small loads and has an average of 28 gallons per load.RighTemp - the Harmony washer's temperature management system - monitors and regulates wash bath temperatures within 5 degree F of the target temperature for any wash cycle. This accuracy is achieved using a thermistor located beneath the wash basket to monitor incoming water during fill (instead of monitoring water temperature at the inlet valve). The thermistor controls the hot and cold inlet valves to achieve desired wash temperatures.As wash action begins The Infusor and wash basket lock together and rotate back and forth to thoroughly mix detergent and water and to evenly distribute the clothes in a highly concentrated detergent solution. The arc and speed of this Wash Basket, is adapted to fabric type. Delicate fabrics are gently rotated while heavier fabrics are rotated more vigorously.Centrifusion - the second type of basket wash action - ensures optimal cleaning. The locked Infusor and basket begin a clockwise spin faster, centrifugal force pulls concentrated cleaning solution through fabrics. This wash action deeply and safely cleans fabrics. After several seconds of clockwise spin, the basket will slow down and stop. The cleaning solution pools back into the wash basket, before the locked basket reverses direction to spin counterclockwise, achieving the same Centrifusion cleaning action. These rotations change direction four times before going to Infusor Wash action.Following Centrifusion, the basket and Infusor will unlock for Infusor Wash: where the Infusor alone oscillates to evenly distribute the wash load and continue to clean items by moving the detergent solution through the load. The redistribution of fabrics helps ensure that lint and dirt do not become trapped.Harmony repeats Centrifusion and Infusor Wash before entering the first Conditioning Spin.The basket and Infusor lock for the Conditioning Spin. The basket spins very slowly at first to allow dirty wash water and lint to drain through the holes in the bottom of the basket before a higher spin begins. When the washer senses that the excess water has drained, the spin speed accelerates to the Cyclone Spin.The Cyclone Spin is also adaptive to fabric type. The basket ramps up to moisture extracting spin speeds which can be as slow as 350 RPMs for delicates or as fast as 1010 RPM for heavy items. The spin is designed to extract as much water/detergent as is possible with no harm to fabrics.Next, Harmony will begin the first rinse called a Spray Rinse. During Spray Rinse, the Infusor and basket turn at a slow speed while fresh, clean water is added to the wash load. Fresh water further reduces the detergent concentration in fabrics by diluting the saturated detergent for extraction into the rinse water. Spin with drain will remove this first rinse water and prepare the wash load for a final rinse.Harmony retrieves the information it gathered for Adaptive Fill and uses that information to refill for the Final Rinse. Cold water enters the basket through the fabric softener dispenser to dilute the softener into the basket and rinse the dispenser clean. he wash basket fills to the optimal level and goes into a basket wash where the clothes are pulled through clean water for final rinsing.A final Conditioning Spin and Cyclone Spin finishes the cycle.
