Definitions

  • WASHER EXTRACTOR AND METHOD INVENTOR POY, Russell, H., a US citizen, of 601 Baronne Street, Number 3B, New
  • the present invention relates to washer extractors, more particularly to an improved washer extractor that uses high velocity overflow rinsing to eliminate most or all of the fill and drain steps typically associated with prior art washer extractors. Even more particularly, the present invention relates to an improved washer extractor that uses a high velocity of water to increase the hydraulic pressure on the soil in the fabric articles and suspended in the wash liquor, thus reducing the amount of rinse water required.
  • a typical wash formula comprises between 6 and 15 steps, depending on linen soil classification.
  • the design of the present invention provides an improved washer extractor.
  • This invention uses high velocity overflow rinsing to eliminate most, if not all, fill and drain steps.
  • the high velocity of the water increases the hydraulic pressure on the soil in the linen and suspended in the wash liquor, thus reducing the amount of rinse water required.
  • Typical water consumption with this system is between about one (1) and two (2) gallons (4 and 8 liters) per pound (0.45 kg) of processed linen.
  • Figure 1 is a schematic diagram of the preferred embodiment of the apparatus of the present invention.
  • FIG. 1 shows the preferred embodiment of the apparatus of the present invention, designated generally by the numeral 10.
  • Washer extractor apparatus 10 provides a machine 11 which can be in the form of a drum, extractor, or any other machine capable of washing textiles such as linens and/or extracting water from textile articles such as linens.
  • Machine or drum 11 provides drum interior 12.
  • Tank 13 can be used to mix fresh cold and fresh hot water. The mixture of hot/cold water is then pumped to machine 11 interior 12.
  • Tank 13 provides tank interior 14 where hot and cold source water is mixed to provide fluid having a selected temperature.
  • Tank 13 can be drained using flow line 21 and valve 22.
  • a first influent flow line 15 can be used to add fresh cold water to tank 13 interior 14.
  • First influent flow line 15 can be provided with valve 16.
  • Flow line 15 connects to a fresh cold water source 17.
  • Second influent flow line 18 can also be provided with a valve 19.
  • valve 18 connects to a fresh hot water source 20.
  • the valves 16 and 19 are modulated in order to provide a water volume in tank 13 interior 14 of a selected temperature.
  • the water in tank 13 interior 14 is transmitted via flow line 23 to pump 24.
  • the machine 11 is filled with water at a temperature of preferably about 120 degrees F (49 degrees C).
  • the machine 11 interior 12 is filled with selected fabric articles to be rinsed, such as linen articles.
  • Water in the tank 13 is transmitted via the flow line 23 to the machine 11 interior 12 to provide a liquor ratio of about four (4) pounds ( 1.8 kg) liquor per pound (0.45 kg) of fabric article or linen, plus absorbed water.
  • alkali can be added to the mixture of water and linen or fabric articles in machine 11 interior 12.
  • Water is then pulsed flowed into interior 12 via inlet nozzle or inlet orifice 44 (see arrow 25) at a volume of between about one half (0.5) and two (2.0) gallons (1.9 and 7.6 liters) per pound (0.45 kg) for the last sixty (60) seconds of a rinsing step.
  • Selected chemicals from chemical source 27 can be added to the mixture of water and fabric articles as a second step of the method of the present invention (see arrow 26 in figure 1).
  • detergent and/or alkali can be added to the water and fabric article mixture in tank 11.
  • the pump 24 delivers between about 0.35 and 0.6 gallons (1.33 and 2.3 liters) of water per pound (0.45 kg) of linen in about two (2) minutes.
  • a sour solution can then be added to the machine 11 interior 12.
  • the normal fluid level is thus represented schematically by the dotted line 45 in figure 1.
  • Water so discharged via overflow drain flow line 28 can flow through opened valve 29 to tee fitting 30.
  • the overflow liquid can then be drained to sewer as indicated by arrow 35 or recovered to tank 13 as indicated by arrow 32.
  • valve 34 in drain line 33 is closed and valve 31 is opened.
  • the liquor is then extracted from the machine 11 via flow line 36.
  • This extraction can be accomplished by opening valve 39 or 42 and closing the other of these two valves.
  • Flow line 36 and valve 42 can be used to recover this extracted liquor.
  • valve 39 is closed and valve 42 is opened.
  • Arrow 37 in figure 1 illustrates a recovery of extracted liquid with return to tank
  • valve 42 is closed and valve 39 is opened. Extracted fluid than discharges to sewer via drain flow line 40 and valve 39 as illustrated by arrow 41 in figure 1.
  • a tee fitting 38 can be provided to mate flow lines 36 and 40 as seen in figure 1. This tee fitting 38 communicates with drain line 40 for discharging any selected fluid to sewer as illustrated by arrow 41 in Figure 1.

Abstract

L'invention concerne une méthode de lavage de linge avec une laveuse-essoreuse comprenant un réservoir pour contenir le linge et un liquide de lavage. Le liquide de lavage est pompé du réservoir vers l'intérieur de la laveuse-essoreuse. Le rapport entre le poids de liquide de lavage et le poids de linge est d'environ 4 pour 1, plus l'eau absorbée. Le fluide est envoyé par impulsions vers le linge à un volume entre 0,5 et 2 gallons (2 à 8 litres) par livre (0,45 kg) de linge pendant un intervalle de temps sélectionné. Des produits chimiques de lavage sont ajoutés dans la laveuse-essoreuse. L'eau est envoyée dans la laveuse-essoreuse à un débit entre 0,35 et 0,6 gallon (1,33 à 2,3 litres) d'eau par livre (0,45 kg) de linge durant l'intervalle de temps sélectionné.
