Description

Technical Field

[0001] The present invention belongs to the technical field of dirt cleaning, and specifically relates to a cleaning machine and a cleaning method, which are suitable for most scenes where dirt and grease need to be cleaned, especially tableware cleaning. Background Art

[0002] In all walks of life, such as industrial production, daily life, and medical care, there are scenes where dirt needs to be cleaned. For example, cleaning of tobacco oil in the tobacco industry, cleaning of household or commercial tableware, cleaning of medical supplies, cleaning of oil tanks, cleaning of toilets, etc. The cleaning methods in the prior art mainly include the main washing stage, the rinsing stage, and the drying stage. Detergents are added in the main washing stage to remove stains that are difficult to clean, such as oil stains, blood stains, and urine alkali. Since detergents are added, a special rinsing device is required to remove the bubbles generated by the detergents.

[0003] The cleaning method of adding cleaning agent has the following problems:

[0004] 1. After using detergent, no matter how you rinse, there will be detergent residue, and as long as there is residue, it will cause damage in some aspects. For example, in the scenario of tableware washing, tableware with chemical reagents residue will cause damage to the human body after use; in the scenario of laundry, clothes with chemical reagents residue may cause skin allergies or skin diseases.

[0005] 2. After cleaning with cleaning agents, the discharged cleaning agents will cause soil compaction, and the cleaning agents will also cause groundwater pollution and seriously damage the living environment. If the cleaning agents are treated at the discharge end, professional environmental protection equipment will inevitably be required, which will inevitably cause additional expenses and increase the cost of cleaning.

[0006] In some cleaning scenarios where the cleaned items need to be dried, a special drying module is also required to dry the cleaned items, such as washing tableware. In order to make the cleaned items dry quickly, a common method is to add a drying agent, and then use hot air and other means to accelerate the drying of the cleaned items. The drying method of adding a drying agent has the following problems: after drying with a drying agent, the drying agent forms a layer of film on the surface of the cleaned items that will not disappear, and the drying agent is more harmful to the human body than the cleaning agent. For example, in an application scenario such as tableware washing, when people use this kind of tableware, part of the drying agent will inevitably enter the human body along with the food, causing harm. Summary of the invention

[0007] In view of the above problems, the present invention aims to provide a cleaning machine that can remove dirt without adding cleaning agents and can achieve rapid drying after cleaning without taking drying measures.

[0008] The technical solution to the problem of the present invention is: a cleaning machine, comprising:

[0009] A washing system suitable for flushing away dirt;

[0010] A water treatment system, the water treatment system comprising a water weak alkalization module, a first water magnetization module, and a water flow channel; the water weak alkalization module comprises a shell with a water inlet and a water outlet, and a filter material encapsulated in the shell that can make water weakly alkaline; the first water magnetization module comprises a first tube with magnetic conductivity, and a magnet arranged on the first tube to form a magnetic field in the first tube area, the first tube having a water inlet and a water outlet; the water flow channel comprises a water inlet and a water outlet;

[0011] The water weak alkalization module and the first water magnetization module are sequentially arranged between the water inlet and the water outlet of the water flow channel along the water flow direction of the water flow channel;

[0012] The water inlet of the water weak alkalization module is connected to the water flow channel, the water outlet of the water weak alkalization module is connected to the water inlet of the first tube of the first water magnetization module, and the water outlet of the first tube of the first water magnetization module is connected to the water outlet of the water flow channel;

[0013] The water outlet of the water flow channel is connected to the water inlet of the washing system.

[0014] In the above technical scheme, the main function of the weak alkalinity module is to make water weakly alkaline, and the main function of the first water magnetization module is to magnetize water to form small molecular clusters of water. In the process of water passing through the weak alkalinity module and the first water magnetization module, the dipole moments of the two HO bonds of the water molecules cannot be offset, the positive and negative charge centers do not overlap, and the entire molecule has a higher polarity. The polarity of the water molecules and the positive and negative charges of the oil stains form an attraction principle, and the water molecules can easily entrain the oil stains (because there is no emulsification reaction) and take them away, thus achieving the purpose of cleaning stains without detergent.

[0015] The magnetization process is set after the weak alkalization process, and the water obtained by the washing system is the smallest possible small molecular cluster water. On the one hand, in the process of cleaning dirt, the water has stronger permeability and can better wrap the dirt and then clean it; on the other hand, the smaller the small molecular cluster water is, the easier it is to evaporate, and the items being washed are less likely to be covered with water droplets, and the items are easier to dry. In this way, the purpose of natural drying can be achieved without using drying agents or other drying methods.

[0016] As a further improvement of the above scheme, it also includes an ozone generating module, which includes an ozone generator and a delivery pipe connected to the ozone generator and connecting the ozone to the water flow channel; the access point of the delivery pipe is located between the water outlet of the water weak alkalization module and the first pipe water inlet of the first water magnetization module.

[0017] In the above-mentioned further improved scheme, the addition of the ozone generating module mainly plays two roles. First, sterilization and disinfection. In some application scenarios with disinfection requirements (such as dishwashing), there are relevant testing standards and requirements, and ozone is added to meet the relevant requirements; second, ozone is a strong oxidant with certain decontamination ability. During the cleaning process, it can work better with small molecular clusters of water to remove stains.

[0018] One feasible solution is that a second water magnetization module is provided between the water outlet of the water weak alkalization module and the delivery pipe access point of the ozone generation module, and the second water magnetization module has the same structure as the first water magnetization module;

[0019] The first pipe water inlet of the second water magnetization module is communicated with the water outlet of the water weak alkalization module, and the first pipe water outlet of the second water magnetization module is communicated with the water inlet of the first pipe of the first water magnetization module.

[0020] The above scheme adds one more level of water magnetization module, the purpose of which is to enhance the magnetization effect and make the water form small molecular clusters as small as possible.

[0021] One feasible solution is to provide a plurality of second water magnetization modules between the water outlet of the water weak alkalization module and the delivery pipe access point of the ozone generation module, and two adjacent second water magnetization modules are connected in sequence;

[0022] And / or, a plurality of first water magnetization modules are provided between the water outlet of the water flow channel and the access point of the delivery pipe of the ozone generating module, and two adjacent first water magnetization modules are connected in sequence.

[0023] The above scheme adds more levels of water magnetization modules, the purpose of which is also to enhance the magnetization effect and make the water form small molecular clusters as small as possible.

[0024] An improved solution is to further include a static mixer with a water inlet and a water outlet, wherein the static mixer is arranged between the water outlet of the water flow channel and the water inlet end of the washing system, the water inlet of the static mixer is connected to the water outlet of the water flow channel, and the water outlet of the static mixer is connected to the water inlet end of the washing system.

[0025] The purpose of setting up a static mixer is to fully mix ozone and water to facilitate the sterilization, disinfection and decontamination capabilities.

[0026] One possible implementation is to have no drying module.

[0027] The drying module here refers to the structure that the washing machine in the prior art generally has to accelerate the drying of items. Some are hot air systems integrated into the washing system, which use hot air to dry the items after the main washing and rinsing stages are completed; some are independent drying devices, which transfer the cleaned items to the drying device for drying or drying. In most cases, a drying accelerator is added to achieve quick drying. Since the above solution uses a water treatment system, it has the characteristics of quick drying, so the drying module can be omitted, saving the cost of the drying stage.

[0028] An optional solution is that the half width of water flowing out of the water outlet of the first tube of the last water magnetization module is less than 60HZ.

[0029] A specific solution is that it also includes a drainage system connected to the washing system; the washing system includes a flushing device for flushing dirt, a water supply module for supplying water to the flushing device, and a water collection part for receiving water;

[0030] The water delivery module comprises a water storage tank connected to the water outlet of the water flow channel, and the water storage tank is connected to the flushing device through a pipeline;

[0031] The water collecting part is connected with the drainage system. The water collecting part or the drainage system is connected with a return pipe. The return pipe is communicated with the water storage tank. Valves are arranged on the drainage system and the return pipe.

[0032] In the prior art, due to the addition of detergents, wastewater generated in both the main wash stage and the rinse stage cannot be recycled because it contains chemicals. Most cleaning equipment is directly discharged into the natural environment, causing environmental pollution. In some cleaning scenarios, wastewater can be partially recycled, such as dishwashers. The prior art dishwasher uses wastewater by recycling wastewater containing detergents to the pre-wash equipment in the pre-wash stage, because detergents also need to be added in the pre-wash stage for preliminary washing of large particles of dirt.

[0033] However, no matter how the wastewater in the prior art is used, the amount of water used in the main wash stage and the rinsing stage has not been reduced at all, because the water used in these two stages requires clean water. The water consumption of the cleaning machine is extremely large. The current cleaning equipment uses at least 5 liters of water per minute in the main wash and rinsing stages, which means that the amount of wastewater discharged is also at least 5 liters per minute. Such a large amount of water is delivered to the pre-wash stage, and the pre-wash stage cannot use it up, so the current operation generally recycles the water in the rinsing stage for use in the pre-wash stage, and the dirtier water in the main wash stage is still directly discharged. In general, the total amount of water used in the main wash and rinsing stages of the prior art is huge, and the current recycling methods cannot change this problem.

[0034] In the solution of the present invention, since detergent is not used, the water in the rinsing stage is not polluted and is very clean. The rinsing water is recycled to the water storage tank through the return pipe and can be used for rinsing and main washing. In this way, the water in the rinsing stage is discharged without any waste, the total water consumption is greatly reduced, and water resources are saved.

[0035] Furthermore, the flushing device includes a first spray device disposed above the water collecting portion, and a second spray device disposed in the water collecting portion area and arranged opposite to the first spray device;

[0036] The water storage tank is connected to the first spray device and the second spray device through pipelines respectively;

[0037] The water collecting part is connected to the first spraying device and the second spraying device respectively through pipelines;

[0038] The water delivery module also includes a delivery pipeline that can deliver water from the water storage tank to the water collection part.

[0039] Furthermore, it also includes a rack, a storage rack, and a protective cover connected to the rack and openable, wherein the rack includes an equipment room arranged at the bottom; the water delivery module, the water treatment system, and the drainage system are arranged in the equipment room;

[0040] The water collecting part is arranged above the equipment room, and the water receiving surface and the protective cover of the water collecting part are enclosed to form a washing room; the water collecting part is provided with a first heating element for heating water; the water storage tank is provided with a second heating element for heating water;

[0041] The storage rack is arranged in the water collection area and between the first spray device and the second spray device. In a specific solution, the magnet includes at least one magnet group arranged along the axial direction of the first tube, each magnet group includes two magnets, the magnets are fixedly arranged on the outer surface of the first tube, and the opposite magnetic poles of the two magnets are opposite;

[0042] The magnetic field parameters between the two magnets are 5000-6000 Gauss.

[0043] Furthermore, there are multiple magnet groups, and the arrangement of adjacent magnet groups is such that their orthographic projections in the axial direction of the first tube are perpendicular to each other. The purpose of the perpendicular arrangement is to allow water on all sides to be magnetized when water flows through the tube.

[0044] In a feasible solution, each magnet group is wrapped with a magnetic locking member to prevent magnetic leakage.

[0045] Furthermore, the first water magnetization module also includes a shell with a closed cavity, the first tube is inserted into the closed cavity of the shell, the closed cavity is filled with a rare earth filler with heat conduction and magnetic locking effects, and a heating component and a sensor for monitoring temperature are provided in the peripheral area of ​​the first tube.

[0046] Accordingly, in order to solve the problem of water resource waste, the present invention also provides a cleaning method, comprising the above-mentioned cleaning machine, and the cleaning steps are as follows:

[0047] a) In the water treatment stage, the tap water is treated by the water weak alkalization module and the water magnetization module to form small molecular cluster water, reaching the level of half width of the water less than 60HZ;

[0048] b) During the main wash phase, the treated water is passed from the water storage tank into the flushing device to rinse the items to be washed, and the flushing wastewater is discharged through the drainage system;

[0049] c) During the rinsing stage, the drainage system is closed, the return pipe is opened, and the water in the water tank is passed into the flushing device to rinse the items to be cleaned. The rinsing water flows back to the water tank through the return pipe for recycling.

[0050] The remarkable effects of the present invention are:

[0051] 1. The water weak alkalization module cooperates with the water magnetization module, and the magnetization program is set after the weak alkalization program, so that the water obtained at the end where water is needed is small molecular cluster water as small as possible. Small molecular cluster water can easily carry away oil and dirt, so as to achieve the purpose of cleaning stains without detergent; at the same time, the smaller the small molecular cluster water is, the easier it is to evaporate, the less likely the washed items are to hang water droplets, and the easier the items are to dry, so as to achieve the purpose of fast and natural drying without drying agents or other drying methods.

[0052] 2. Since no detergent is required, no bubbles will be generated, which can greatly shorten the rinsing time and improve the cleaning efficiency.

[0053] 3. Due to the characteristics of rapid natural drying, drying measures such as drying agents and / or drying modules can be omitted.

[0054] 4. The rinsing water is recycled to the water storage tank through the return pipe and can be used for rinsing and main washing. In this way, there is no waste of water in the rinsing stage, the total water consumption is greatly reduced, and water resources are saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0069] For the convenience of description, the description of the relative position relationship of each component (such as: up, down, left, right, etc.) is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.

[0070] Example 1

[0071] Figures 1 to 6An embodiment of the present invention is shown, a cleaning machine, comprising a washing system suitable for washing dirt, a drainage system connected to the washing system, and a water treatment system. The water treatment system comprises a water weak alkalization module 2, a first water magnetization module 3, and a water flow channel 1.

[0072] The water weak alkalinization module 2 comprises a housing 21 with a water inlet and a water outlet, and a filter material encapsulated in the housing 21 that can make water weakly alkaline. The filter material makes water weakly alkaline by a physical method, which is a prior art. There are many filter materials that can make water weakly alkaline by a physical method in the prior art. This embodiment uses medical stone, tourmaline, ochre, hexacyclic stone, calcium sulfite and nano zeolite uniformly mixed as the filter material.

[0073] The housing 21 can be designed in different forms according to the amount of water to be treated. For example, in a small amount of water treatment scenario, a specific embodiment may be that the housing of the water weak alkalization module includes a chamber, and the filter material is encapsulated in this chamber. In a large amount of water treatment scenario, a specific embodiment may be that the housing 21 of the water weak alkalization module 2 includes a plurality of adjacent or separated chambers, and the plurality of chambers are connected in sequence, and the filter material is encapsulated in different chambers. In this way, the amount of filter material can be increased, thereby increasing the processing capacity. Figure 2 In the illustrated structure, the housing 21 is separated into two chambers connected in series.

[0074] The first water magnetization module 3 includes a first tube 31 with magnetic conductivity and a magnet 32 ​​arranged on the first tube 31 to form a magnetic field in the area of ​​the first tube 31. The first tube 31 has a water inlet and a water outlet. A specific embodiment is that the magnet 32 ​​includes at least one magnet group arranged along the axial direction of the first tube 31. Each magnet group includes two magnets. The magnet is fixedly arranged on the outer surface of the first tube 31, and the opposite magnetic poles of the two magnets are opposite. The magnetic field magnetic force parameter between the two magnets is 5000-6000 Gauss. Preferably 5500 Gauss.

[0075] An optional embodiment is that the magnet groups are provided in plurality, and the adjacent magnet groups are arranged in such a manner that their orthographic projections in the axial direction of the first tube 31 are perpendicular to each other. A feasible embodiment is that the spacing between the opposite poles of the two magnets is 4-6 mm to ensure sufficient magnetic field strength.

[0076] A feasible embodiment is that the half width of the water flowing out of the water outlet of the first tube 31 of the last water magnetization module is less than 60HZ. Preferably, it is 40-50HZ. The half width is a key detection index of small molecular cluster water, which directly reflects the compactness of the water molecule cluster. It mainly relies on nuclear magnetic resonance (NMR), 17O-NMR technology to qualitatively determine the size of water molecule clusters. By measuring the half width of the vibration frequency of water, the size of the water molecule cluster can be known. The smaller the HZ value, the smaller the water molecule cluster.

[0077] A feasible embodiment is that each magnet group is wrapped with a magnetic locking member 33 to prevent magnetic leakage. The magnetic locking member 33 is a cylindrical iron block. A hole matching the size of the magnet group is opened in the center of the iron block, and the magnet group is sleeved in the hole. Due to the wrapping of the iron block, the magnetic field formed by the magnet group will not leak magnetic flux, further improving the magnetization effect.

[0078] Further, the first water magnetization module 3 also includes a shell 34 with a closed cavity. The first tube 31 is inserted into the closed cavity of the shell 34. The closed cavity is filled with a rare earth filler with heat conduction and magnetic locking effects. A heating component 36 and a sensor 35 for monitoring the temperature are provided in the peripheral area of ​​the first tube 31. The heating component 36 is provided in the peripheral area of ​​the first tube 31, which means that the setting position of the heating component 36 can be adjusted according to the actual design situation, and can be set in the closed cavity or on the shell 34. In principle, the required temperature can be guaranteed. The heating component 36 in this embodiment is arranged in a sealed cavity, and the temperature sensor is arranged on the shell.

[0079] The rare earth filler is a material in the prior art, including at least one of graphene powder, tourmaline electric raw stone powder, Bian stone powder, germanium stone powder, biochar powder, medical stone powder, and volcanic rock silicate.

[0080] The water flow channel 1 includes a water inlet and a water outlet. The water outlet of the water flow channel 1 is connected to the water inlet of the washing system. The connection described here can be a direct connection or an indirect connection. In principle, it is only necessary to ensure that the water path is connected and the water in the water flow channel 1 can flow into the washing system. The water weak alkalization module 2 and the first water magnetization module 3 are sequentially arranged between the water inlet and the water outlet of the water flow channel 1 along the water flow direction of the water flow channel 1.

[0081] The water inlet of the water weak alkalization module 2 is connected to the water flow channel 1, and the water outlet of the water weak alkalization module 2 is connected to the water inlet of the first tube 31 of the first water magnetization module 3. The water outlet of the first tube 31 of the first water magnetization module 3 is connected to the water outlet of the water flow channel 1.

[0082] An improved embodiment scheme is that it also includes an ozone generating module 4, which includes an ozone generator and a delivery pipe connected to the ozone generator and connected to the water flow channel 1. The access point of the delivery pipe is located between the water outlet of the water weak alkalization module 2 and the water inlet of the first pipe 31 of the first water magnetization module 3. The ozone generating module 4 is a prior art, and its main purpose is to generate ozone, and it only needs to be able to pass ozone into the water flow channel.

[0083] As a further improved embodiment, a static mixer 6 with a water inlet and a water outlet may be further included, and the static mixer 6 is arranged between the water outlet of the water flow channel 1 and the water inlet end of the washing system. The water inlet of the static mixer 6 is connected to the water outlet of the water flow channel 1. The water outlet of the static mixer 6 is connected to the water inlet end of the washing system. The purpose of setting the static mixer 6 is to fully mix ozone with water to facilitate the sterilization and decontamination capabilities.

[0084] An optional embodiment is that a second water magnetization module 5 is further provided between the water outlet of the weakly alkaline water module 2 and the delivery pipe access point of the ozone generating module 4. The second water magnetization module 5 has the same structure as the first water magnetization module 3. The water inlet of the first tube 31 of the second water magnetization module 5 is connected to the water outlet of the weakly alkaline water module 2. The water outlet of the first tube 31 of the second water magnetization module 5 is connected to the water inlet of the first tube 31 of the first water magnetization module. The purpose of adding one more level of water magnetization module is to enhance the magnetization effect so that the water forms small molecular clusters of water as small as possible.

[0085] Of course, in order to achieve a stronger magnetization effect and make the water form small molecular clusters as small as possible, more levels of water magnetization modules can be connected at different positions and selected according to different application scenarios. For example, one embodiment is to provide a plurality of second water magnetization modules 5 between the water outlet of the water weak alkalization module 2 and the delivery pipe access point of the ozone generation module 4, and two adjacent second water magnetization modules 5 are connected in sequence;

[0086] And / or, a plurality of first water magnetization modules 3 are provided between the water outlet of the water flow channel 1 and the delivery pipe access point of the ozone generating module 4, and two adjacent first water magnetization modules 3 are connected in sequence.

[0087] In the prior art, washing machines are generally equipped with drying modules that accelerate the drying of items. Some are hot air systems integrated into the washing system, which dry items with hot air after the main wash and rinse stages; some are independent drying devices that transfer the washed items to the drying device for drying or drying. In most cases, drying agents are added to achieve quick drying. The solution of this embodiment uses a water treatment system, which has the characteristic of quick drying, so the drying module is omitted, and the cost of the drying stage is omitted.

[0088] The washing system includes a flushing device 8 for flushing dirt, a water supply module 9 for supplying water to the flushing device 8, and a water collecting part 10 for receiving water. The water supply module 9 includes a water storage tank 91 connected to the water outlet of the water flow channel 1 (when a static mixer 6 is installed, the water storage tank 91 is connected to the water outlet of the static mixer 6). The water storage tank 91 is connected to the flushing device 8 through a pipeline. The water collecting part 10 is connected to the drainage system 7. The water collecting part 10 or the drainage system 7 is connected to a return pipe 92. The return pipe 92 is connected to the water storage tank 91. Valves are provided on the drainage system 7 and the return pipe.

[0089] Further, the flushing device 8 includes a first spray device 81 disposed above the water collecting portion 10, and a second spray device 82 disposed in the water collecting portion 10 area and arranged opposite to the first spray device 81. The water storage tank 91 is connected to the first spray device 81 and the second spray device 82 through pipelines. The water collecting portion 10 is connected to the first spray device 81 and the second spray device 82 through pipelines. The water delivery module 9 also includes a delivery pipeline 95 that can deliver water from the water storage tank 91 to the water collecting portion 10.

[0090] Furthermore, it also includes a rack 11, a storage rack, and a protective cover 12 connected to the rack 11 and openable. The rack 11 includes an equipment room 13 arranged at the bottom. The water delivery module 9, the water treatment system, and the drainage system 7 are arranged in the equipment room 13.

[0091] The water collecting part 10 is arranged above the equipment room 13. The water receiving surface of the water collecting part 10 and the protective cover 12 together form a washing room 14. The water collecting part 10 is provided with a first heating element for heating water. The water storage tank 91 is provided with a second heating element for heating water. The rack is arranged in the area of ​​the water collecting part 10 and is located between the first spray device 81 and the second spray device 82.

[0092] The following is an example of a dishwasher used in the field of tableware washing, and further illustrates the above structure:

[0093] The water collecting part 10 is the water tank of the dishwasher, and the first spray device 81 and the second spray device 82 are rotating spray heads, which are all prior art. The water delivery module 9 also includes a first pump 93 for pumping water from the water storage tank into the first spray device 81 and the second spray device 82, respectively, and a second pump 94 for pumping water from the water collecting part 10 into the first spray device 81 and the second spray device 82, respectively. In the washing room 14 area, a delivery pipeline outlet is opened on the side wall of the frame 11 above the water collecting part 10, and water is delivered from the water storage tank 91 to the water collecting part 10 through the outlet. This waterway is to provide water for the main washing stage. A third pump can be used for delivery. In this embodiment, in order to reduce the number of parts, no additional water pump is added, but the first pump 93 is selected as a variable frequency pump, so that water can be supplied to the flushing device 8 and the water collecting part 10.

[0094] The first heating element is used to heat the water in the water collecting part 10, and the second heating element is used to heat the water in the water storage tank 91 to ensure the water temperature in the main washing stage and the rinsing stage. The water temperature of the dishwasher is controlled between 60-85 degrees, and the temperature can be different in different washing stages.

[0095] This embodiment also provides a cleaning method, and the cleaning steps are as follows:

[0096] a) In the water treatment stage, the tap water is treated by the water weak alkalization module and the water magnetization module to form small molecular cluster water, reaching the level of half width of the water less than 60HZ;

[0097] b) During the main wash phase, the treated water is passed from the water storage tank 91 to the flushing device 8 to rinse the items to be washed, and the flushing waste water is discharged through the drainage system;

[0098] c) During the rinsing stage, the drainage system 7 is closed, the return pipe is opened, and the water in the water tank 91 is passed into the flushing device 8 to rinse the items to be cleaned. The rinsing water flows back to the water tank 91 through the return pipe for recycling.

[0099] The specific working process of this embodiment is as follows:

[0100] Water treatment stage: tap water enters the water flow channel, and then is treated by the water weak alkalization module 2 to make the water weakly alkaline, and then undergoes one or more levels of magnetization in the water magnetization module to magnetize the water into small molecular clusters of water, which is then evenly mixed with ozone to form weak alkaline water that can sterilize and disinfect and has extremely strong permeability. The treated water enters the water storage tank.

[0101] In the main wash stage, the first pump presses the hot water in the water tank 91 into the outlet of the side wall of the frame 11 through the delivery pipeline 95, and the water enters the water collecting part 10 and is further heated. The water in the water collecting part 10 is pumped into the first spray device 81 and the second spray device 82 through the second pump 94 installed at the bottom of the water collecting part to wash the items. While washing, the water is drained from the drainage system 7, and clean water continuously flows into the water collecting part 10.

[0102] In the rinsing stage, after the main wash stage is completed, the drainage system 7 is closed and the return pipe is opened. The first pump 93 pumps the water in the water tank 91 through the pipe to the first spray device 81 and the second spray device 82 for rinsing, and the rinsing water enters the water tank 91 through the return pipe 92 for recycling. The temperature in the rinsing stage is higher, the small molecular water is more likely to evaporate, and the washed items will dry quickly.

[0103] Since detergent is not used, the water in the rinsing stage is not polluted and is very clean. The rinsing water is recycled to the water storage tank 91 through the return pipe 92 and can be used for rinsing and main washing. In this way, the water in the rinsing stage is discharged without any waste, the total water consumption is greatly reduced, and water resources are saved.
