Definitions

  • the invention relates to systems for washing laundry and more particularly to a system for washing laundry applicable to a laundry which combines washing laundry and water treatment.
  • the system or method involves using electrolyzed water or nano ion water, ozone, air or hydrogen nano bubbles in water as a replacement of the laundry detergents or chemical cleaning fluids.
  • a conventional automatic washing machine comprises a sodium chloride addition device and an electrolysis device. Compressed ozone air and electrolyzed water flow to a perforated basket of a washing machine to mix with dirty clothes by controlling concentration of sodium chloride. The dirty clothes are thus cleaned by the mixture in a wash cycle.
  • Another conventional washing machine comprises a bubbles generation device and a control device.
  • the bubbles are nano bubbles which are effective in increasing solubility of the chemical cleaning fluids.
  • the present inventor has filed several patent applications about electrolysis devices for generating nano ion water, nano bubbles generation devices and washing systems.
  • the applications are not related to laundry washing, instead related to washing glass, sapphire , silicon parts, metal parts, electronic components ceramics, and wafers in the process of manufacturing inorganic items or semiconductor manufacturing process.
  • they lay the foundation for the technology of washing laundry without using laundry detergents or chemical cleaning fluids.
  • the present inventor recently filed a patent application, entitled "System for washing laundry, nano bubbles ion water generation device and method of washing laundry”.
  • the application can solve the problem of environmental pollution caused by used laundry detergents or chemical cleaning fluids. But the application is only applicable to a single washing machine used by a home or individual. That is, the application is not applicable to self-serve laundry or business laundry having a plurality of washing machines.
  • the invention provides a system for washing laundry comprising a cleaning fluid electrolytic hydrogen nano bubbles generation device for receiving tap water and electrolyzing the tap water to generate nano hydrogen bubbles and nano ion water or alkaline electrolytic water together as a cleaning fluid; a recycled water nano bubbles generation device for receiving tap water and recycled water by the system and generating ozone nano bubbles from a mixture of the tap water and the recycled water; and at least one washing machine capable of performing one of a plurality of wash cycles including pre-wash, main wash, and rinse; wherein in the pre-wash or rinse, the recycled water nano bubbles generation device supplies the tap water having ozone nano bubbles to each of the at least one washing machine through a pre-wash or rinse line so that each of the at least one washing machine is configured to perform the pre-wash or rinse; and wherein in the main wash, the cleaning fluid electrolytic hydrogen nano bubbles generation device supplies the main solution to each of the least one washing machine through a cleaning fluid line so that each of the at least one washing machine
  • a pre-wash or rinse water filter wherein after the pre-wash or rinse has been performed, water flows through a pre-wash or rinse recycled water line into the pre-wash or rinse water filter and the pre-wash or rinse water filter is configured to filter the water.
  • a pre-wash or rinse water treatment system wherein after the filtered water has flowed to the pre-wash or rinse water treatment system, the pre-wash or rinse water treatment system is configured to treat the filtered water; wherein the treated water as recycled water flows to the recycled water nano bubbles generation device; and wherein the recycled water nanometer bubbles generation device is configured to generates ozone nano bubbles in the recycled water.
  • a cleaning fluid filter wherein after the main wash has been performed, water flows through a cleaning fluid recycled line to the cleaning fluid filter; and wherein the cleaning fluid filter is configured to removes solid particles from the water.
  • a dirty cleaning fluid ozone nano bubbles treatment device wherein after the recycled water has flowed to the washed cleaning fluid ozone nano bubbles treatment device, the washed cleaning fluid ozone nano bubbles treatment device is used with electrolysis device as an advance oxidation system for washed water treatment; and wherein the treated water flows to the cleaning fluid electrolytic hydrogen nano bubbles generation device.
  • FIG. 1 schematically depicts a system for washing laundry of the invention.
  • a system for washing laundry of the invention comprises a cleaning fluid electrolytic hydrogen nano bubbles generation device 6 for receiving tap water and electrolyzing the tap water to generate nano ion water (or alkaline electrolytic water) and nano hydrogen bubbles together as a cleaning fluid; a recycled water nano bubbles generation device 3 for receiving tap water and water recycled by the system and generating ozone nano bubbles from the water; and at least one washing machine 7 (a plurality of washing machines 7 are shown) capable of performing one of a plurality of wash cycles including pre-wash, main wash and rinse.
  • the recycled water nano bubbles generation device 3 supplies the tap water having ozone nano bubbles to each washing machine 7 through a pre-wash or rinse line 8 so that each washing machine 7 can perform the pre-wash or rinse.
  • the cleaning fluid electrolytic hydrogen nano bubbles generation device 6 supplies the main solution to each washing machine 7 through a cleaning fluid line 9 so that each washing machine 7 can perform the main wash.
  • Tap water is supplied to the cleaning fluid electrolytic hydrogen nanometer bubbles generation device 6 through a hose.
  • an electrolysis device is activated to electrolyze the soften tap water to generate nano ion water (or alkaline electrolytic water) and nano hydrogen bubbles together as a cleaning fluid in which device parameters including current, voltage, water flow rate and concentration of electrolyte in a cation electrolyte tank are set and controlled by a detection device; and the cleaning fluid is stored in the cleaning fluid electrolytic hydrogen nano bubbles generation device 6 after the device parameters reach set values.
  • the negative charge of the nano hydrogen bubbles surfaces are greater than that of nano bubbles of other gas. Thus, the nano hydrogen bubbles have larger washing capability.
  • the tap water is supplied to the recycled water nano bubbles generation device 3.
  • the recycled water nano bubbles generation device 3 activates to generate ozone nano bubbles in the tap water which is stored in the recycled water nano bubbles generation device 3.
  • Ozone nano bubbles can increase washing capability of the tap water and have an improved oxidation effect which can kill microorganisms, remove and oxidize dirt from clothes.
  • Ozone gases are converted to ozone bubbles which have advantages of a prolonged period of time of existence in water, increased surface contact area, increased reaction, and decreased ozone consumption.
  • washing Dirty clothes are placed in a perforate basket of the washing machine 7 and next an automatic washing is performed.
  • the washing includes the following sequential wash cycles: pre-wash, first spin, main wash, second spin, rinse, and third spin as detailed below.
  • the recycled water nano bubbles generation device 3 supplies the tap water having ozone nano bubbles to each washing machine 7 through a pre-wash (or rinse) line 8 so that dirty clothes can be washed initially.
  • the perforated basket of the washing machine 7 rotates to remove dirty water from the washed clothes.
  • the dirty water is drained the washing machine 7 to a pre-wash (or rinse) water filter 1 through a pre-wash (or rinse) recycled water line 10.
  • Water is filtered by the pre-wash (or rinse) water filter 1 to remove dirt and then the filtered water flows to a pre-wash (or rinse) water treatment system 2 for treatment.
  • the treatment includes biological, chemical and physical treatment methods.
  • the treated water i.e., recycled water
  • flows to the recycled water nano bubbles generating device 3 which activates to generates ozone nano bubbles in the recycled water.
