Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular to a detergent-free and disinfectant-free three-oxygen washing machine. Background Art

[0002] With rising living standards, washing machines have become ubiquitous in every household, becoming an essential appliance. Assuming one person has five people in one household, 50% of households own one, resulting in a total of 140 million washing machines in China. Existing washing machine technology requires the use of detergents such as liquid or powdered laundry detergent. To sterilize clothes, washers without high-temperature sterilization also require disinfectant. Assuming a daily load of laundry, using a conservative 50 liters of water per load (40-70 liters for a front-loading washing machine, 100-130 liters for a top-loading washing machine), this generates 2.555 billion tons of wastewater annually. This is particularly true for large-scale specialized laundry facilities (such as those washing hospital bedsheets, clothing, hotels, and school linens). These facilities use higher concentrations of detergents and disinfectants, and residual chemicals are released into the environment along with the wastewater, causing environmental pollution and wasting energy on wastewater treatment. Furthermore, these large-scale laundry facilities have high operating costs and require approval from environmental protection authorities, as well as the establishment of qualified treatment facilities. In addition, waste packaging such as detergents, washing powder, and disinfectants requires a lot of energy to process in order to reduce pollution to the environment.

[0003] Oxygen (O₃) is a strong oxidant that quickly breaks down dirt and removes it from clothing fibers. It also effectively breaks down oil stains, removing stains that are difficult to remove with conventional detergents. It also increases the nutrient content of water, making clothes naturally softer and smoother. Furthermore, washing with O₃ water reduces shrinkage and increases clothing durability. O₃ has a bactericidal capacity 150 times that of chlorine and a sterilization rate 3,000 times faster. When dissolved in water, O₃ becomes trioxide water, its bactericidal effect is even more pronounced. Trioxide water can replace bleach and most liquid disinfectants. Therefore, O₃ disinfection is safer than other methods, leaves no residue, and poses no secondary pollution, making it an environmentally friendly disinfection method.

[0004] Nowadays, many washing machines use ozone water to kill bacteria on clothes. The conventional method of producing ozone water in a washing machine is to introduce external air into an ozone generator, and then introduce the ozone generated by the ozone generator into the washing water in the washing drum along with the air flow, so that the ozone dissolves in the washing water to form ozone water. One problem with this method is that the ozone introduced into the bottom of the drum is contained in the air bubbles. Since the water level of the washing water in the drum is low and the solubility of ozone in water is low, most of the ozone generated by the ozone generator does not dissolve in the water but overflows to the outside of the water surface with the bubbles, resulting in a very low ozone concentration in the washing water and limited sterilization effect. Summary of the Invention

[0005] To this end, the technical problem to be solved by the present invention is to provide a detergent- and disinfectant-free ozone washing machine. A centrifugal pump is used to circulate liquid, and negative pressure is formed in the throat section of the Venturi tube of the Venturi ejector to suck the ozone gas generated by the ozone generating unit into the liquid circuit. The ozone gas is then efficiently mixed by a dual-flow mixing component and circulated to the upper end of the liquid storage tank. The ozone water forms a closed circulation loop, ensuring a certain ozone concentration in the water, increasing the ozone concentration in the water in the washing drum, and ensuring the washing and sterilization effects.

[0006] The technical solutions of the present invention are as follows:

[0007] A detergent-free and disinfectant-free ozone washing machine comprises a drum, an ozone production mechanism, and a water-gas mixing mechanism. The water-gas mixing mechanism mixes ozone produced by the ozone production mechanism with water to form ozone water, which is then transported into the drum.

[0008] The three-oxygen production mechanism includes a three-oxygen generation unit and a liquid storage tank. The water-gas mixing mechanism is connected to the three-oxygen generation unit and the centrifugal pump respectively to form a closed circulation loop.

[0009] Furthermore, the tri-oxygen generating unit adopts a tri-oxygen generator, uses more than 99% oxygen (gaseous oxygen, liquid oxygen) as raw material, uses the tri-oxygen generator to produce tri-oxygen without nitrogen oxides by a corona method, and mixes it through a water-gas mixing mechanism to obtain trioxide water.

[0010] Furthermore, the trioxygen generating unit adopts a trioxygen production module, and uses electrolysis to add oxygen production liquid (purified water) into the trioxygen production module to produce trioxygen without nitrogen oxides, and then mixes it through a water-gas mixing mechanism to obtain trioxide water.

[0011] Furthermore, the water-gas mixing mechanism includes a centrifugal pump and a venturi ejector, the inlet end of the venturi ejector is connected to the bottom outlet end of the liquid storage tank through a centrifugal pump pipeline, the throat end pipeline of the venturi ejector is connected to the ozone generating unit, the outlet end pipeline of the venturi ejector is connected to the top inlet end of the liquid storage tank, and the liquid storage tank is also connected to the drum through a pipeline.

[0012] Furthermore, the outlet end of the venturi ejector is connected to a liquid storage tank through a dual-flow mixing assembly, and the dual-flow mixing assembly includes a mixing tube, and the mixing tube includes a cutting portion and a flow blocking portion connected in sequence, the cutting portion is arranged near the outlet end of the venturi ejector, and the flow blocking portion is arranged near the liquid storage tank.

[0013] Furthermore, the cutting portion includes cutting blades arranged in a staggered manner along the axial direction of the mixing tube in a cross-shaped pattern, and the inclination angle of the cutting blades relative to the central axis of the mixing tube is 30-60°;

[0014] The flow-blocking portion includes a guide column and a mushroom head. One end of the guide column is fixedly connected to the inner wall of the mixing tube, and the other end of the guide column extends toward the central axis of the mixing tube and its end is fixedly connected to the mushroom head. Two or more flow-blocking portions are closely arranged along the circumference of the inner wall of the mixing tube to form a flow-blocking ring, and at least one flow-blocking ring is arranged on the axial inner wall of the mixing tube.

[0015] Furthermore, the drum is further connected to a delay storage box, in which a carrying box for carrying polyacrylamide is provided, and the tri-oxygen generating unit is connected to the carrying box through a sand core gas distributor.

[0016] Furthermore, the delay storage box is connected to a stirring mechanism corresponding to the carrying box through a bracket, and the stirring mechanism includes a bevel gear plate arranged on the lower end face of the top end of the bracket through a flange, and a driving motor is provided on the upper end face of the top end of the bracket, and the output shaft of the driving motor passes through the bracket and the flange and is connected to a steering rod, and one end of the steering rod away from the output shaft of the driving motor extends radially along the bevel gear plate and is connected to a stirring rod, one end of the stirring rod passes through the steering rod and is connected to a reversing wheel meshing with the bevel gear plate, and the other end of the stirring rod is connected to a stirring rod inside the carrying box.

[0017] Furthermore, the bracket is provided with a guide frame protruding from the bracket near the bottom of the carrier box, and the end of the guide frame away from the bracket is located on the central axis of the carrier box. The other end of the stirring rod is connected to the guide frame through a universal ball and the stirring rod passes through the guide frame and is connected to the stirring rod.

[0018] Furthermore, the trioxygen flow rate of the trioxygen generating unit is set to x1, and the water source flow rate is set to x2. Then, the trioxygen concentration y=11.7735+0.0459x1-0.0060x2. When the water source flow rate is constant, the concentration of trioxygen increases with the increase of the trioxygen flow rate. When the trioxygen flow rate is constant, the concentration of trioxygen decreases with the increase of the tap water flow rate. By adjusting the trioxygen flow rate and the water source flow rate, trioxygen water of different concentrations can be prepared.

[0019] A method for using a detergent-free and disinfectant-free ozone washing machine, comprising a drum of the washing machine, an ozone production mechanism, and a water-gas mixing mechanism. The water-gas mixing mechanism mixes ozone produced by the ozone production mechanism with water to form ozone water, which is then transported into the drum.

[0020] The ozone production mechanism includes an ozone generating unit and a liquid storage tank, and the water-gas mixing mechanism is connected to the ozone generating unit and the centrifugal pump to form a closed circulation loop.

[0021] The water-gas mixing mechanism includes a centrifugal pump and a venturi ejector, wherein the inlet end of the venturi ejector is connected to the outlet end at the bottom of the liquid storage tank through a centrifugal pump pipeline, the throat end pipeline of the venturi ejector is connected to the ozone generating unit, and the outlet end pipeline of the venturi ejector is connected to the inlet end at the top of the liquid storage tank, and the liquid storage tank is also connected to the drum through a pipeline;

[0022] The drum is also connected to a storage box, in which a carrying box for carrying polyacrylamide is provided, and the trioxygen generating unit is connected to the carrying box through a sand core gas distributor;

[0023] The steps include:

[0024] S1. Prepare a gel by placing 1.0 g / L polyacrylamide by weight into a carrier box. Use a washing machine controller to add an appropriate amount of tap water to the carrier box to dissolve the polyacrylamide. Turn on the stirring mechanism in the carrier box and stir at a speed of 30-50 rpm to evenly disperse the polyacrylamide to form a hydrosol.

[0025] S2. After the trioxygen generating unit completes trioxygen production, the pipeline between the liquid storage tank and the centrifugal pump is opened. The centrifugal pump circulates the liquid flowing out of the liquid storage tank, creating a negative pressure in the venturi throat section of the venturi ejector. The trioxygen gas generated by the trioxygen generating unit is sucked into the liquid circuit in the venturi ejector through a pipeline to form a trioxygen water mixture. The trioxygen water mixture is mixed by a dual-flow mixing assembly and circulated to the upper end of the liquid storage tank, forming a closed circulation loop. The trioxygen water mixture stored in the liquid storage tank (with a concentration of 2-3 ppm) is pumped into the drum for washing clothes.

[0026] S3. When washing more than two loads of clothes at a time, another pipeline of the ozone generating unit pumps the ozone that has not completely entered the venturi ejector into the hydrosol in the carrier box through the sand core gas distributor, dissolving the ozone in the hydrogel and extending the half-life of the ozone hydrogel to more than 20 hours. After washing one load of clothes, the ozone hydrogel is directly introduced into the drum to wash the next load of clothes.

[0027] The working principle and beneficial effects of the present invention are:

[0028] 1. The present invention provides a detergent- and disinfectant-free ozone washing machine. A centrifugal pump circulates liquid, creating negative pressure in the throat section of the venturi tube of a venturi ejector to draw ozone gas generated by an ozone generating unit into a liquid circuit. The ozone gas is then efficiently mixed by a dual-flow mixing assembly and circulated to the upper end of a liquid storage tank. The ozone water forms a closed circulation loop. Under the action of a washing machine control unit, the ozone water is delivered into a drum for washing clothes. The washed clothes are washed and sterilized without the need for adding detergents or disinfectants, thereby reducing environmental pollution.

[0029] 2. The present invention provides a detergent- and disinfectant-free ozone washing machine. Ozone and water are initially mixed in a venturi ejector and then enter a mixing tube. Under the combined action of a cutting portion and a flow-blocking portion, a radial circulation mixing effect of the ozone solution is formed. The ozone solution mixture is cut and refined into micro-nano bubbles, achieving efficient mixing of dispersed phases such as gas-liquid and liquid-liquid with a continuous phase, enhancing mass transfer, and ensuring uniform mixing of the ozone solution.

Implementation Method

[0042] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0043] The fixed connection described in this device refers to fixation by welding, threaded fixation, etc., and different fixing methods are used in combination with different usage environments. The rotating connection refers to the axial fixation of the bearing by baking it on the shaft and realizing rotation through an elastic retaining ring. The sliding connection refers to the connection through the sliding of the slider in the slide groove. The hinged connection refers to the movable connection through a pin shaft and a short shaft. The required sealing is achieved by a sealing ring or an O-ring.

[0044] The present invention provides a three-oxygen washing machine free of detergent and disinfectant, such as Figure 1As shown, it also includes an ozone production mechanism and a water-gas mixing mechanism. The water-gas mixing mechanism mixes the ozone produced by the ozone production mechanism with water to form ozone water and transports the mixture into the drum 1.

[0045] The ozone production mechanism includes an ozone generating unit 5 and a liquid storage tank 2. The water-gas mixing mechanism is connected to the ozone generating unit 5 and the liquid storage tank 2 respectively to form a closed circulation loop. The water-gas mixing mechanism includes a centrifugal pump 3 and a venturi ejector 4. The inlet end of the venturi ejector 4 is connected to the bottom outlet end of the liquid storage tank 2 through a pipe of the centrifugal pump 3. The throat end pipe of the venturi ejector 4 is connected to the ozone generating unit 5. The outlet end pipe of the venturi ejector 4 is connected to the top inlet end of the liquid storage tank 2. The liquid storage tank 2 is also connected to the drum 1 through a pipe.

[0046] The liquid storage tank 2 is connected to the centrifugal pump 3 through a pipe. The inlet end of the venturi ejector 4 is connected to the bottom outlet end of the liquid storage tank 2 through a pipe of the centrifugal pump 3. The throat end of the venturi ejector 4 is connected to the tri-oxygen generating unit 5 through a pipe. The outlet end of the venturi ejector 4 is connected to the top inlet end of the liquid storage tank 2 through a pipe. The liquid storage tank 2 is also connected to the drum 1 through a pipe. A liquid storage tank 2 is fixed by a foot bracket. A pipe is connected to the centrifugal pump 3 below the liquid storage tank 2. The outlet of the centrifugal pump 3 is then connected to the venturi ejector 4 and the dual-flow mixing assembly 6 in sequence. Finally, the liquid pipe is connected to the liquid storage tank 2. The centrifugal pump 3 is used to circulate the liquid. The negative pressure is generated in the venturi throat section of the venturi ejector 4, which draws the tri-oxygen gas generated by the tri-oxygen generating unit 5 into the liquid circuit. After efficient mixing in the dual-flow mixing assembly 6, it is circulated to the upper end of the liquid storage tank 2. The tri-oxygen water forms a closed circulation loop. Under the action of the washing machine control unit, the tri-oxygen water is delivered into the drum for washing clothes.

[0047] Combine Figure 2 and Figure 3 The outlet end of the venturi ejector 4 is connected to the liquid storage tank 2 through a dual-flow mixing assembly 6. The dual-flow mixing assembly 6 includes a mixing tube 61. The mixing tube 61 includes a cutting portion 62 and a flow blocking portion 63 sequentially arranged inside the mixing tube 61. The cutting portion 62 is arranged near the outlet end of the venturi ejector 4. The flow blocking portion 63 is arranged near the liquid storage tank 2. The cutting portion 62 includes cutting blades 621 that are sequentially staggered and arranged in a cross shape along the axial direction of the mixing tube 61. The cutting blades 62 The inclination angle relative to the central axis of the mixing tube 61 is 30-60 degrees. The flow blocking portion 63 includes a guide post 632 and a mushroom head 631. One end of the guide post 632 is fixedly connected to the inner wall of the mixing tube 61, and the other end of the guide post 632 extends toward the central axis of the mixing tube 61 and its end is fixedly connected to the mushroom head 631. Two or more flow blocking portions 63 are closely arranged along the circumference of the inner wall of the mixing tube 61 to form a flow blocking ring. At least one flow blocking ring is arranged on the axial inner wall of the mixing tube 61.

[0048] The venturi ejector 4 achieves preliminary mixing of the trioxygen gas and water. The centrifugal pump 3 drives the water to flow at high speed from the inlet section to the contraction section. At this time, due to the gradual decrease in cross-sectional size, the liquid flow rate and dynamic pressure continue to increase. In the throat section, the instantaneous dynamic pressure and flow rate of the liquid rise to a maximum, and the static pressure decreases to a minimum. This creates a pressure difference between the inside and outside of the throat, thereby forming a negative pressure that draws the trioxygen gas into the throat to mix with the liquid. Finally, the trioxygen water passes through the diffusion section of the venturi ejector 4. The pipe cross-sectional size gradually increases, and its pressure and trioxygen water flow rate both decrease.

[0049] The trioxide-water mixture, initially mixed by the Venturi ejector 4, enters the mixing tube 61. The mixed liquid flows through the cutting portion 62. Under the cutting action of the cross-cutting blades 621, the mixed liquid is continuously cut and refined into the gas phase, liquid phase, and mixed phase flows, causing strong turbulence inside the mixing tube 61. The mixed liquid then enters the flow-blocking portion 62. A mushroom-shaped mixing enhancement structure is provided inside the cylindrical body of the flow-blocking portion 62. As the mixed liquid advances, it is obstructed by the cylindrical mushroom heads 631. The water flow is continuously dispersed and disrupted, and the flow direction is continuously changed, pushing the central fluid toward the periphery and the peripheral fluid toward the center, thereby achieving a good radial mixing effect. At the same time, the rotation of the fluid itself also occurs between adjacent mushroom heads 631, forming a radial circulation mixing effect, ultimately achieving efficient mixing of dispersed phases such as gas-liquid and liquid-liquid with the continuous phase, enhancing mass transfer, and achieving uniform mixing of the trioxide-water.

[0050] Combine Figure 4 The drum 1 is also connected to a delay storage box 7, which is provided with a carrier box 9 for carrying polyacrylamide. The trioxygen generating unit 5 is connected to the carrier box 9 through a sand core gas distributor 8. The delay storage box 7 is connected to a stirring mechanism corresponding to the carrier box 9 through a bracket 10. The stirring mechanism includes a bevel gear disk 12 provided on the lower end surface of the top of the bracket 10 through a flange 11. The upper end surface of the top of the bracket 10 is provided with a drive motor 13. The output shaft of the drive motor 13 passes through the bracket 10 and the flange 11 and is connected to a steering rod 14. The steering rod 14 is away from the output of the drive motor 13. One end of the shaft extends radially along the bevel gear disc 12 and is connected to a stirring rod 16. One end of the stirring rod 16 passes through the steering rod 14 and is connected to a reversing wheel 15 that meshes with the bevel gear disc 12. The other end of the stirring rod 16 is connected to a stirring rod 18 inside the carrier box 9. The bracket 10 is provided with a guide frame 17 protruding from the bracket 10 near the bottom of the carrier box 9. The end of the guide frame 17 away from the bracket 10 is on the central axis of the carrier box 9. The other end of the stirring rod 16 is connected to the guide frame 17 through a universal ball 19, and the stirring rod 16 passes through the guide frame 17 and is connected to the stirring rod 18.

[0051] Since the preparation of trioxygen takes a long time, and the solubility of trioxygen in water at normal temperature, normal pressure is about 13 times higher than that of oxygen and 25 times higher than that of air, when washing more than two rolls of clothes at a time, the trioxygen water stored in the liquid storage tank is very easy to decompose during the second washing, thereby reducing the bactericidal and disinfecting effect of trioxygen. Therefore, the trioxygen that has not completely entered the venturi ejector is pumped into the hydrosol in the carrier box through a sand core gas distributor through another pipeline of the trioxygen generating unit, dissolving the trioxygen in the hydrogel and extending the half-life of the trioxygen hydrogel to more than 20 hours. After washing one roll of clothes, the trioxygen hydrogel is directly introduced into the drum to wash the next roll of clothes, thereby achieving multiple washes and saving waiting time. Example

[0052] This embodiment is a three-oxygen washing machine that does not require detergent or disinfectant. Figure 5 As shown, using more than 99% oxygen (gaseous oxygen, liquid oxygen) as a raw material, the tri-oxygen generating unit produces tri-oxygen free of nitrogen oxides through a corona method, which is then mixed with water and gas to produce tri-oxide water, which enters the drum of a washing machine to clean and disinfect clothes. This embodiment is suitable for washing machines weighing more than 25 kg and is suitable for large washing places. A 180-liter bottle of liquid oxygen can be used for 150 to 200 hours.

[0053] The washing process includes the following steps:

[0054] 1) When the power is turned on, the human-machine interface 07A will display the machine self-test status;

[0055] 2) Open the oxygen cylinder 01A and adjust the oxygen pressure (0.1~0.15Mpa) and flow rate (0.8~1.5m 3 / h), the internal program of ozone concentration and flow rate has been preset and automatically adjusted according to the weight of the clothes;

[0056] 3) Add clothes (do not wash easily discolored clothes together with natural clothes. The washing machine has a special washing program for easily discolored clothes. Select this function to wash such clothes). Press the start button. The washing machine will automatically adjust the weight of the clothes and select the water volume. The tap water inlet valve 12A opens and water starts to flow in.

[0057] 4) At this time, the ozone generating unit 04A enters the preheating state and starts to produce ozone. The ozone flows into the dual-flow mixing assembly 09A through the pipeline. When the water level reaches the preset level, the dual-flow mixing assembly 09A starts to mix the ozone into the tap water for circulation.

[0058] 5) The drum 14A of the washing machine washes clothes. Each wash cycle lasts 8-20 minutes. After each wash cycle, the drain valve 10A is opened to drain the clothes (the drained water can be used to sterilize and deodorize the sewer). The washing cycle is generally three times. During the washing process, any undissolved tri-oxygen in the water is degraded into oxygen by the tri-oxygen degrader 13A and discharged.

[0059] 6) After washing and dehydration, the drying device 11A starts to dry the clothes. The residual three-oxygen smell on the clothes will be completely volatilized in about 15 minutes and degraded into oxygen by the three-oxygen degrader 13A and discharged;

[0060] 7) The whole process is completed and the clothes are taken out. The clothes are now dry and sterile.

[0061] The present invention does not require the addition of any detergents or disinfectants, but utilizes the unique sterilization, disinfection and decontamination capabilities of trioxygen. The washing effect is better than that of existing washing machines, and the sterilization rate can reach 99.99%. The discharged water is not only pollution-free, but also has the effect of sterilizing and deodorizing the sewer pipes. Example

[0062] This embodiment is a three-oxygen washing machine that does not require detergent or disinfectant. Figure 6 As shown, trioxygen is produced by electrolysis. Oxygen-generating liquid (purified water) is added to the trioxygen generating unit to produce trioxygen free of nitrogen oxides. The resulting trioxygen water is then mixed in a dual-flow mixing assembly and fed into the washing machine drum to clean and sterilize clothing. This embodiment is suitable for household washing machines weighing 3 to 10 kg and is suitable for areas with poor tap water quality (tap water conductivity exceeding 500 μS / cm). The washing machine consumes 10 ml of oxygen-generating liquid (purified water) per hour of operation. Assuming one hour of laundry per day, a bag of oxygen-generating liquid (purified water) needs to be replaced every three months, costing approximately 10 yuan.

[0063] The washing process includes the following steps:

[0064] 1) When the power is turned on, the human-machine interface 18B will display the machine self-test status;

[0065] 2) Open the oxygen cylinder and adjust the oxygen pressure (0.1~0.15Mpa) and flow rate (0.8~1.5m 3 / h), the internal program of ozone concentration and flow rate has been preset and automatically adjusted according to the weight of the clothes;

[0066] 3) Put in the clothes (do not wash clothes that are easy to discolor together with clothes of natural color. The washing machine 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 will automatically select the amount of water according to the weight of the clothes. The tap water inlet valve 20 opens and water starts to flow in.

[0067] 4) The ozone generating unit enters the preheating state and starts to produce ozone. The ozone enters the dual-flow mixing component 19B through the pipeline. After the preset water level is reached, the dual-flow mixing component 19B starts to mix the ozone into the tap water for circulation.

[0068] 5) The drum 22B of the washing machine washes clothes. Each wash cycle lasts 8-20 minutes. After each wash cycle, the drain valve 23B is opened to drain the clothes (the drained water can be used to sterilize and deodorize the sewer). The washing cycle is generally three times. During the washing process, any undissolved tri-oxygen in the water is degraded into oxygen by the tri-oxygen degrader 21B and discharged.

[0069] 6) After washing and dehydration, the drying device 24B starts to dry the clothes. The residual three-oxygen smell on the clothes will be completely volatilized in about 15 minutes and degraded into oxygen by the three-oxygen degrader 21B and discharged;

[0070] 7) The whole process is completed and the clothes are taken out. The clothes are now dry and sterile. Example

[0071] This embodiment is a three-oxygen washing machine that does not require detergent or disinfectant. Figure 7 As shown, oxygen-generating liquid (purified water) is produced online and automatically injected into the oxygen-generating liquid tank. Oxygen-free oxygen is produced by electrolysis, and mixed by a dual-flow mixing assembly to obtain trioxide water. The water enters the washing machine drum to clean and disinfect clothes. This embodiment is suitable for household washing machines with a capacity of 3 to 10 kg. This embodiment is suitable for areas with good tap water quality (tap water conductivity not exceeding 500 μs / cm). The cost of washing clothes is negligible, and the cost of manufacturing the washing machine is slightly higher.

[0072] The washing process includes the following steps:

[0073] 1) When the power is turned on, the human-machine interface 17C will display the machine self-test status;

[0074] 2) The oxygen liquid tank level sensor 04C automatically detects the oxygen liquid / tri-oxygen tank. When the liquid level is low, the online liquid preparation device 01C automatically prepares the liquid. The cooling water tank temperature sensor 12C detects the cooling water tank 11C. When the liquid level is low, it needs to be manually added. It is added once for a new machine and does not need to be added later.

[0075] 3) Add clothes (do not wash easily discolored clothes together with natural clothes. The washing machine has a special washing program for easily discolored clothes. Select this function to wash such clothes). Press the start button. The washing machine will automatically adjust the weight of the clothes and select the water volume. The tap water inlet valve 19C opens and water starts to flow in.

[0076] 4) At this time, the 35A constant current power supply 09C automatically connects to the oxygen production module 07C, and oxygen production begins. The cooling water circulation pump 14C starts, and the trace amount of gas and water produced by the oxygen production module 07C is brought into the cooling water tank 11C. When the cooling water tank temperature sensor 12C detects that the temperature of the oxygen production liquid / oxygen production tank reaches 28°C, the refrigeration device 15C starts and cools the oxygen production liquid and oxygen production tank 02C through the cooling coil 03C. When the temperature is below 24°C, the refrigeration device 15C stops working.

[0077] 5) Oxygen flows into the dual-flow mixing assembly 18C through a pipe. When the water reaches the set water level, the dual-flow mixing assembly 18C starts to mix the ozone into the tap water for circulation, while washing the clothes. The washing time is 8-10 minutes. After each wash, the drain valve 22 is opened to drain the water (the drained water can be sent to the sewer for sterilization and deodorization). The washing process is generally three times. During the washing process, the ozone that is not dissolved in the water is degraded into oxygen by the ozone degrader 20C and discharged.

[0078] 6) After washing and dehydration, the drying device 23C is started to dry the clothes. The residual three-oxygen smell on the clothes will be completely volatilized in about 15 minutes and degraded into oxygen by the three-oxygen degrader 20C and discharged;

[0079] 7) The whole process is completed and the clothes are taken out. The clothes are now dry and sterile.

[0080] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
