Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly washing machines, and in particular to a tri-oxygen generating device for an environmentally friendly washing machine and an environmentally friendly washing machine. Background Art

[0002] With the continuous improvement of living standards, washing machines have entered thousands of households and become one of the indispensable household appliances in people's daily lives. Existing washing machine washing technology must add detergents such as laundry liquid and washing powder. If you want to sterilize and disinfect clothes, washing machines without high-temperature disinfection must also add disinfectant. Based on a conservative calculation of washing clothes once a day and using 50 liters of water each time (drum washing machine: about 40L-70L, pulsator washing machine: about 100L-130L), the annual sewage generated is as high as 2.555 billion tons, especially in large-scale specialized washing places (washing hospital sheets, clothes; hotels, school sheets). The large amount of detergents and disinfectants used in these places are at higher concentrations. The residual chemical detergents are discharged into the nature along with the sewage, causing environmental pollution and wasting energy consumption in treating sewage. In addition, waste packaging such as detergents, washing powders, disinfectants, etc. requires a lot of energy to process to reduce pollution to the environment.

[0003] Most detergents are artificially synthesized organic compounds, such as laundry detergent and dishwashing liquid, which contain high levels of phosphorus (sodium phosphate). After washing, the phosphorus-containing wastewater flows into rivers and lakes, causing eutrophication of water bodies, resulting in vigorous reproduction of algae in the water bodies, causing fish and other aquatic organisms to die due to lack of oxygen. At the same time, it also causes great harm to human skin, especially infants' and young children's underwear, and even causes disease. If clothes and bed sheets in public places are not thoroughly disinfected, there is a risk of virus cross-infection.

[0004] The main active ingredients of detergents are surfactants and cleaning agents. In addition, there are auxiliary ingredients such as bleach, fluorescent brighteners, corrosion inhibitors, foam regulators, enzymes, etc. Commercial detergents generally contain one or several surfactants and several cleaning agents due to their large usage and the wide variety of fabric sources. Commercial washing not only requires a large amount of detergent, but also a large amount of gas, washing water and electricity consumption, which puts great pressure on large-scale specialized laundry businesses and the environment. Summary of the Invention

[0005] This invention proposes an environmentally friendly ozone generator for washing machines and an environmentally friendly washing machine. This solves the existing problem of washing machines relying on detergents and disinfectants for daily laundry, generating large amounts of wastewater. This problem is particularly severe in large, specialized laundry facilities, where residual chemicals are discharged into the environment along with the wastewater, causing environmental pollution and wasted energy in wastewater treatment. Furthermore, the high phosphorus content in detergents causes eutrophication of water bodies, harming human skin, particularly infant and toddler underwear and women's underwear, and potentially causing illness. Furthermore, commercial laundry consumes large amounts of detergent, gas, water, and electricity, placing significant pressure on businesses and the environment.

[0006] The technical solution of the present invention is as follows: an environmentally friendly ozone generator for a washing machine, applied to a washing machine, comprising: an oxygen cylinder, a pressure reducing valve, a flow meter, an ozone generator, an ozone concentration monitor, a control system, a water inlet mechanism, and a dehydration mechanism;

[0007] The input end of the pressure reducing valve is communicated with the output end of the oxygen cylinder;

[0008] The input end of the flow meter is communicated with the output end of the pressure reducing valve;

[0009] The input end of the ozone generator is connected to the output end of the flow meter;

[0010] The input end of the ozone concentration monitor is connected to the output end of the ozone generator;

[0011] The control system is used to control the operation of the equipment;

[0012] The water inlet mechanism is connected to the washing machine and is used to fill water into the washing machine;

[0013] The dehydration mechanism is arranged on the washing machine and is used for discharging sewage.

[0014] Preferably, the control system includes: a 24V power supply, a human-machine interface and a main control circuit board;

[0015] The human-machine interface is electrically connected to a 24V power supply;

[0016] The main control circuit board is electrically connected to the human-machine interface, and the main control circuit board is electrically connected to the 24V power supply.

[0017] Furthermore, the water inlet mechanism includes: a water-air mixing pump and a tap water inlet valve;

[0018] The output end of the water-gas mixing pump is connected to the output end of the ozone concentration monitor;

[0019] The output end of the tap water inlet valve is communicated with the output end of the water-gas mixing pump.

[0020] Furthermore, the dehydration mechanism includes: a drain valve, a drying device and a tri-oxygen degrader;

[0021] The drain valve is connected to the washing machine;

[0022] The drying device is arranged on the washing machine;

[0023] The three-oxygen degrader is arranged on the washing machine.

[0024] In the aforementioned solution, the environmentally friendly washing machine includes the ozone generator for an environmentally friendly washing machine as described in any one of the above solutions.

[0025] The working principle and beneficial effects of the present invention are:

[0026] 1. In the present invention, there is no need to add any detergent or disinfectant. The unique sterilization, disinfection and decontamination capabilities of ozone are utilized, and the washing effect is better than that of existing washing machines. The sterilization rate can reach 99.99%. The discharged water is not only pollution-free, but also has the effect of sterilization and deodorization on the sewer pipes.

[0027] 2. In the present invention, there are 140 million washing machines in China; 2.555 billion tons of sewage are generated each year. Based on the electricity consumption of 0.2 kWh per ton (Internet source: sewage treatment power consumption is 0.2-0.3 kWh / m3), 510 million kWh of electricity can be saved each year. Every kWh (kilowatt-hour) of electricity saved saves 0.4 kg of standard coal, and at the same time reduces pollution emissions by 0.272 kg of carbon and 0.785 kg of carbon dioxide, which means that carbon emissions can be reduced by 138.7 million kg and carbon dioxide emissions by 400 million kg each year.

[0028] 3. In the present invention, based on the 1.4 billion population in China and the average annual per capita laundry detergent consumption of 3 kg, the online price of a 3 kg bottle of laundry detergent is about RMB 40. If a 20% discount is applied to the number of people who use laundry detergent (1.12 billion), 1.12 billion × RMB 40 = RMB 44.8 billion, which means RMB 44.8 billion can be saved annually.

[0029] 4. In the present invention, trioxygen is generated through the cooperation between the oxygen cylinder, the pressure reducing valve, the flow meter, the trioxygen generator, the trioxygen concentration monitor, the control system, the water inlet mechanism and the dehydration mechanism. Trioxygen is a strong oxidant that can decompose dirt and separate it from clothing fibers in a short period of time. Trioxygen can also effectively decompose oil stains and remove oil stains that cannot be removed by general detergents. Trioxygen can increase the nutrients in water and make clothes more naturally soft. In addition, washing clothes with trioxygen water can also reduce the shrinkage of clothes and increase the durability of clothes. The bactericidal ability of trioxygen is 150 times that of chlorine, and the bactericidal speed is 3000 times that of chlorine. The bactericidal effect of trioxygen dissolved in water to become trioxide water is more significant. Trioxide water can replace bleach and most liquid disinfectant chemicals. Therefore, trioxygen disinfection is safer than other disinfection methods, will not leave any residue, and will not cause secondary pollution. It is a more environmentally friendly disinfection method. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

This embodiment proposes an environmentally friendly three-oxygen generating device for a washing machine, which is applied to the washing machine 1, including: an oxygen cylinder 2, a pressure reducing valve 3, a flow meter 4, a three-oxygen generator 5, a three-oxygen concentration monitor 6, a control system, a water inlet mechanism and a dehydration mechanism. The input end of the pressure reducing valve 3 is connected to the output end of the oxygen cylinder 2, the input end of the flow meter 4 is connected to the output end of the pressure reducing valve 3, the input end of the three-oxygen generator 5 is connected to the output end of the flow meter 4, and the input end of the three-oxygen concentration monitor 6 is connected to the output end of the three-oxygen generator 5. Through the oxygen cylinder 2, the pressure reducing valve 3, the flow meter 4, the three-oxygen generator 5, the three-oxygen concentration monitor 6, the control system, the water inlet mechanism and the dehydration mechanism, The cooperation between water bodies produces trioxygen, which is a strong oxidant that can decompose dirt in a short time and separate it from clothing fibers. Trioxygen can also effectively decompose oil stains and remove oil stains that ordinary detergents cannot remove. Trioxygen can increase the nutrients in water and make clothes more naturally soft. In addition, washing clothes with trioxygen water can also reduce the shrinkage of clothes and increase the durability of clothes. The bactericidal ability of trioxygen is 150 times that of chlorine, and the bactericidal speed is 3000 times that of chlorine. The bactericidal effect of trioxygen dissolved in water to become trioxide water is more significant. Trioxide water can replace bleach and most liquid disinfectant chemicals, so trioxygen disinfection is safer than other disinfection methods, there will be no residue, no secondary pollution, and it is a more environmentally friendly disinfection method.

[0041] It should also be added that the oxygen cylinder 2 can be purchased from outside and placed directly next to the washing machine 1 for use.

[0042] Among them, the control system is used to control the operation of the equipment. The control system includes: a 24V power supply 7, a human-machine interface 8 and a main control circuit board 9. The human-machine interface 8 is electrically connected to the 24V power supply 7, the main control circuit board 9 is electrically connected to the human-machine interface 8, and the main control circuit board 9 is electrically connected to the 24V power supply 7. Specifically, by connecting the 24V power supply 7 to provide power for the equipment, the operator controls the main control circuit board 9 through the human-machine interface 8 to issue instructions for operation.

[0043] Among them, the water inlet mechanism is connected to the washing machine 1 and is used to fill water into the washing machine 1. The water inlet mechanism includes: a water-gas mixing pump 10 and a tap water inlet valve 11. The output end of the water-gas mixing pump 10 is connected to the output end of the three-oxygen concentration monitor 6, and the output end of the tap water inlet valve 11 is connected to the output end of the water-gas mixing pump 10. Specifically, the tap water inlet valve 11 is connected to the faucet, and the water enters the washing machine 1 through the tap water inlet valve 11.

[0044] Among them, the dehydration mechanism is provided on the washing machine 1 for discharging sewage. The dehydration mechanism includes: a drain valve 12, a drying device 13 and a tri-oxygen degrader 14. The drain valve 12 is connected to the washing machine 1, the drying device 13 is provided on the washing machine 1, and the tri-oxygen degrader 14 is provided on the washing machine 1. Specifically, after washing is completed, the drain valve 12 is opened to drain the water, and then the clothes are dehydrated. At this time, the drying device 13 is started to dry the clothes. The residual tri-oxygen odor on the clothes is degraded into oxygen by the tri-oxygen degrader 14 and discharged.

[0045] The environmentally friendly washing machine 1 includes an ozone generator for an environmentally friendly washing machine according to any one of the above solutions.

[0046] In this embodiment, when the washing machine 1 is washing clothes, the 24V power supply 7 is turned on and the human-machine interface 8 displays the machine standby state;

[0047] Open oxygen cylinder 2 and adjust the oxygen pressure (0.1-0.15 MPa) and flow rate (0.8-1.5 m³ / h). The internal program for the three oxygen concentrations and flow rates has been preset and will automatically adjust according to the weight of the clothes.

[0048] Put in clothes (clothes that are easy to discolor should not be washed together with clothes of natural color. The washing machine 1 has a special washing program for clothes that are easy to discolor. You can select this function to wash such clothes). Press the start button. The washing machine 1 automatically detects the weight of the clothes and automatically selects the amount of water. The water inlet valve 11 opens and starts to fill the washing machine 1 with water.

[0049] At this time, the ozone generator 5 enters the preheating state and starts to produce ozone. The ozone enters the water-gas mixing pump 10. After the preset water level is reached, the water-gas mixing pump 10 starts to mix the ozone into the tap water for circulation.

[0050] The washing machine 1 washes clothes for 8 to 20 minutes. After each wash, the drain valve 12 is opened to drain the clothes (the drained water can be sent to the sewer for sterilization and deodorization). Generally, the clothes are washed three times. During the washing process, the trioxygen that is not dissolved in the water is degraded into oxygen by the trioxygen degrader 14 and discharged.

[0051] After washing is completed and dehydration is carried out, the drying device 13 is started to dry the clothes, and the residual three-oxygen odor on the clothes is degraded into oxygen by the three-oxygen degrader 14 and discharged.

[0052] After the whole process is completed, take out the clothes, which are now dry and sterile.

[0053] Embodiment 2: This solution is applicable to a household washing machine 1 weighing 3 to 20 kg.

The main control board 24 is electrically connected to the constant current power supply 25, and the interactive interface 23 is electrically connected to the main control board 24.

[0055] When the present embodiment is in use, the interactive interface 23 displays the standby state when the power is turned on;

[0056] Turn on the faucet, put in clothes (clothes that are easy to discolor should not be washed together with clothes of natural color. The washing machine 1 has a special washing program for clothes that are easy to discolor. This function can be selected to wash such clothes). Press the start button. The washing machine 1 automatically selects the amount of water according to the weight of the clothes. The water inlet valve 15 opens and starts to fill with water.

[0057] Tap water enters the electrolysis module 16, the constant current power supply 25 is energized, the electrolysis module 16 starts working, generates hydrogen and trioxide water, and enters the washing machine 1. When the water level reaches the set water level, the water inlet valve 15 is closed and washing begins;

[0058] After entering the washing state, hydrogen and trioxide react rapidly with organic matter (dirt) on the clothes, and the concentration of hydrogen and trioxide is consumed and reduced. At this time, the circulating water solenoid valve 17 opens, and the gas-liquid mixing pump 35 draws water from the washing machine 1 tub and the hydrogen and trioxide that have not dissolved in the water into the electrolysis module 16.
