Description

Technical Field

[0001] The present invention belongs to the technical field of dirt cleaning, and specifically relates to a pre-washing device and a cleaning system, 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 mainly include the main wash stage, the rinsing stage, and the drying stage. Detergents are added in the main wash 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] In order to clean thoroughly and improve the cleaning efficiency, pre-washing is performed as needed before entering the main wash stage. Therefore, in many scenarios, pre-washing equipment and main wash equipment are used together. In the process of implementing the present invention, it is found that there are at least the following problems in the prior art:

[0004] 1. The pre-washing stage requires a lot of water. After the pre-washing equipment has been working for a short time, the water in the pre-washing pool will become very dirty. The staff will directly drain the waste water according to the situation, and then add new water to start the next round of pre-washing. Therefore, the amount of water discharged in the pre-washing stage is large, and the demand is also large, which is a great waste of water resources.

[0005] 2. 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.

[0006] 3. 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.

[0007] 4. 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. Some drying measures are hot air systems integrated into the washing system, which are blown dry with hot air after the main wash and rinse stages are completed; some are independent drying devices, which transfer the cleaned items to the drying device for blowing or drying. And in most cases, a drying accelerator is added to achieve quick drying. These methods have the following problems: (a) After drying with a drying accelerator, the drying accelerator forms a layer of film on the surface of the cleaned items that will not disappear, and the drying accelerator is more harmful to the human body than the cleaning agent. For example, in the application scenario of tableware washing, when people use this kind of tableware, part of the drying accelerator will inevitably enter the human body along with the food, causing harm. (b) The drying equipment is expensive, which increases the overall equipment production cost.

[0008] 5. Due to the addition of detergents, the 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 nature, causing environmental pollution. In some cleaning scenarios, wastewater can be partially recycled, such as dishwashers. The existing dishwasher uses wastewater by recycling the wastewater with 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.

[0009] 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. Summary of the invention

[0010] In view of the above problems, the present invention aims to provide a pre-washing device which can improve the utilization rate of water and save water resources.

[0011] The technical solution to the problem of the present invention is: a pre-washing device, comprising:

[0012] A pre-washing tank, suitable for containing objects to be washed, wherein the top of the pre-washing tank is open;

[0013] A filter tank is adjacent to the pre-wash tank, the top of the filter tank is open, and the open surface of the filter tank is lower than the open surface of the pre-wash tank, or is flush with the open surface of the pre-wash tank;

[0014] A stirring device is arranged in the pre-wash tank and is suitable for stirring the water in the pre-wash tank into a vortex and / or turbulent state;

[0015] A first floating object discharge channel is provided in the filter tank, wherein the first floating object discharge channel is provided with an overflow port, and the overflow port is arranged at a height higher than the bottom surface of the filter tank;

[0016] The recovery system comprises a first recovery water pipe with one end connected to the filter tank and the other end connected to the pre-wash tank, and a pumping device for conveying water in the first recovery water pipe.

[0017] In the above scheme, water is used to flush the dirt from the objects to be cleaned into the pre-wash tank, the heavy dirt sinks, and the oil dirt floats on the surface. Most of the oil dirt enters the filter tank by overflow. When the water in the filter tank rises to a certain height, the oil dirt in the filter tank is discharged through the overflow port of the first floating object discharge channel, and the water in the filter tank becomes slightly cleaner water that can meet the needs of pre-washing, and flows back to the pre-wash tank through the first recycling water pipe for reuse. This scheme greatly extends the water utilization time and improves the utilization rate under the same water volume, saving water resources.

[0018] A feasible implementation scheme is that the filter tank is provided with a drain outlet, the first floating object discharge channel includes a pipe body, the overflow outlet is arranged on the pipe body and communicates with the inner cavity of the pipe body; the lower end of the pipe body is sealed and connected to the drain outlet of the filter tank.

[0019] Furthermore, a filter screen is provided at the open portion of the filter pool.

[0020] In a specific implementation, the stirring device includes an air pipe arranged in the pre-washing tank, and an air supply device arranged outside the pre-washing tank and connected to the air pipe, and a plurality of air holes are arranged on the air pipe.

[0021] A feasible implementation scheme is that a device chamber is sunken in the pre-wash tank, a heating element is arranged in the device chamber, the top opening of the device chamber is flush with the bottom of the pre-wash tank, and a filter is arranged at the top opening of the device chamber.

[0022] Furthermore, the pre-wash tank is provided with a drain outlet, and a second floating object discharge channel is provided at the drain outlet of the pre-wash tank. The second floating object discharge channel has the same structure as the first floating object discharge channel and is arranged in the same manner at the drain outlet; a filter is provided around the second floating object discharge channel.

[0023] A feasible implementation scheme is to further include a first water treatment system disposed in the pre-washing tank area and supplying water to the pre-washing tank, wherein the first water treatment system includes a water weak alkalization module, a first water magnetization module capable of magnetizing water to form small molecular cluster water with a half-width less than 60HZ, and a water flow channel;

[0024] The water weak alkalinization 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;

[0025] 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;

[0026] 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.

[0027] 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.

[0028] The magnetization program is set after the weak alkalization program, and the water obtained is the smallest possible small molecular cluster water. On the one hand, during the process of cleaning dirt, the water has stronger permeability and can better wrap the dirt and then clean it.

[0029] Further, a feasible solution is that the first water treatment system also includes an ozone generation module and a static mixer;

[0030] The ozone generating module comprises an ozone generator and a delivery pipe connected to the ozone generator and connected 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;

[0031] The static mixer has a water inlet and a water outlet. 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 can be connected to the open area of ​​the pre-wash tank.

[0032] In the above further improved scheme, the water treatment sequence is weak alkalization of water - passing ozone - magnetization.

[0033] The addition of the ozone generation module plays two main roles. First, it sterilizes and disinfects. Second, ozone is a strong oxidant with a certain decontamination ability. During the cleaning process, it can work better with small molecular water to remove stains. The purpose of setting up a static mixer is to fully mix ozone with water to facilitate the sterilization, disinfection and decontamination capabilities.

[0034] Another feasible solution is that the first water treatment system further includes an ozone generation module and a static mixer;

[0035] The ozone generating module comprises an ozone generator and a delivery pipe connected to the ozone generator and connected to the water flow channel; the connection point of the delivery pipe is located between the first pipe water outlet of the first water magnetization module and the water outlet of the water flow channel;

[0036] The static mixer has a water inlet and a water outlet. 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 can be connected to the open area of ​​the pre-wash tank.

[0037] The water treatment sequence of this scheme is weak alkalization of water - magnetization - ozone.

[0038] Furthermore, at least one second water magnetization module is provided between the water outlet of the first water magnetization module and the delivery pipe access point of the ozone generating module, and the second water magnetization module has the same structure as the first water magnetization module;

[0039] The first pipe water inlet of the second water magnetization module is communicated with the water outlet of the first water magnetization module, and the first pipe water outlet of the second water magnetization module is communicated with the water flow channel.

[0040] The water treatment sequence of this scheme is weak alkalization of water - multi-level magnetization - ozone.

[0041] A feasible implementation scheme is that 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] When there are multiple magnet groups, adjacent magnet groups are arranged in such a manner that their orthographic projections in the axial direction of the first tube are perpendicular to each other.

[0044] 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.

[0045] Accordingly, in order to solve the problem of water waste in the main wash stage, the present invention also provides a washing system, comprising: a main wash machine, and the above-mentioned pre-wash device;

[0046] The main washing machine comprises a washing system suitable for washing dirt, a drainage system connected to the washing system, and a second water treatment system capable of treating water to a half-width of less than 60 Hz, wherein the second water treatment system is connected to the washing system;

[0047] The second water treatment system has the same structure as the first water treatment system;

[0048] The recovery system also includes a second recovery water pipe, one end of which is connected to the filter tank and the other end of which is connected to the drainage system.

[0049] In the above scheme, the dirty water of the main washing machine in the main washing stage can be discharged to the filter tank through the second recycling water pipe, and the floating objects such as oil and dirt can be discharged through the first floating object discharge channel. Then, the water in the main washing stage can be sent to the pre-washing tank through the first recycling water pipe for pre-washing after being purified, so that the water in the main washing stage is not discharged, and the utilization rate of the water in the main washing stage is increased. In addition, the coordinated application of the second water treatment system and the first water treatment system in the above scheme makes it unnecessary to add cleaning agents in both the pre-washing and main washing stages.

[0050] Furthermore, the second water treatment system also includes an ozone generating module;

[0051] The ozone generating module comprises an ozone generator and a delivery pipe connected to the ozone generator and connected 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;

[0052] At least one 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;

[0053] 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.

[0054] The water treatment sequence of this scheme is weak alkalization of water - one or more levels of magnetization - ozone - magnetization.

[0055] In a feasible implementation, 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;

[0056] 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;

[0057] 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.

[0058] In the above scheme, 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.

[0059] 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;

[0060] The water storage tank is connected to the first spray device and the second spray device through pipelines respectively;

[0061] The water collecting part is connected to the first spraying device and the second spraying device respectively through pipelines;

[0062] The water delivery module also includes a delivery pipeline that can deliver water from the water storage tank to the water collection part.

[0063] 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;

[0064] 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;

[0065] The storage rack is arranged in the water collection area and is located between the first spray device and the second spray device.

[0066] The remarkable effects of the present invention are:

[0067] 1. The design of the recycling system enables the pre-wash equipment to independently realize self-recycling of water. Under the condition of the same amount of water, the water utilization time is greatly extended, the utilization rate is improved, and water resources are saved.

[0068] 2. After the first water treatment system is placed in the pre-washing equipment, the water weak alkalization module cooperates with the water magnetization module, and the magnetization program is set after the weak alkalization program. The water obtained is small molecular cluster water as small as possible. Small molecular cluster water can easily carry away oil and dirt, achieving the purpose of pre-washing without using detergent.

[0069] 3. The dirty water from the main washing machine during the main washing stage can be discharged to the pre-washing equipment through the second recycling water pipe, and used for pre-washing after self-purification in the pre-washing equipment, so that the water in the main washing stage is not discharged, which increases the utilization rate of the water in the main washing stage and saves water resources.

[0070] 4. The design of the second water treatment system makes the water used in the main washing machine small-molecule water, which can easily carry away the oil and dirt, so as to achieve the purpose of cleaning the stains without detergent; at the same time, the smaller the small-molecule water, the easier it is to evaporate, and the less likely the washed items are to be covered with water droplets, and the easier the items are to dry, so as to achieve the purpose of fast and natural drying. Due to the characteristics of fast and natural drying, drying measures such as drying agents and / or drying modules can be omitted.

[0071] 5. Since no detergent is required, no bubbles will be generated, which can greatly shorten the rinsing time and improve the cleaning efficiency.

[0072] 6. For the main washing machine itself, 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.

[0073] From the above description of the effects, it can be seen that in terms of water conservation, the water in the main wash stage is completely discharged into the pre-wash equipment for reuse; the water in the rinsing stage is completely recycled to the water storage tank for main wash and rinsing, and the rinsing water is used for the main wash and then enters the pre-wash. In terms of the rinsing water, it has been used in turns of rinsing-main wash-pre-wash; the pre-wash stage not only uses the main wash water, but also has the ability to self-purify and recycle for reuse. From pre-wash to main wash, and then to rinsing, the water is fully utilized many times, which greatly improves the water utilization rate and reduces the total amount of water used in the washing process.

[0097] 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.

[0098] For the convenience of description, 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.

[0099] Figures 1 to 6 An embodiment of the present invention and its variant embodiments are shown, a pre-washing device, including a pre-washing tank 15, a filtering tank 16, an agitating device 17, a first floating object discharge channel 18, and a recovery system 19.

[0100] The pre-washing tank 15 is suitable for containing the objects to be washed. The pre-washing tank 15 is provided with a drain. The top of the pre-washing tank is open.

[0101] The filter pool 16 is adjacent to the pre-wash pool 15. The top of the filter pool 16 is open. The open surface of the filter pool 16 is lower than the open surface of the pre-wash pool 15, or is flush with the open surface of the pre-wash pool 15. When the water in the pre-wash pool 15 overflows the open surface of the filter pool 16, the water will overflow into the filter pool 16.

[0102] The stirring device 17 is arranged in the pre-washing tank 15, and is suitable for stirring the water in the pre-washing tank 15 into a vortex and / or turbulent state. The purpose of the stirring device 17 is to remove large particle residues of the items to be washed. The stirring device 17 is a prior art, and there are many structural forms, such as impeller stirring, bubble stirring, etc. A specific feasible embodiment is that the stirring device 17 includes an air pipe 171 arranged in the pre-washing tank 15, and an air supply device 172 arranged outside the pre-washing tank 15 and connected to the air pipe 171, and a plurality of air holes 173 are arranged on the air pipe. The air supply device 172 can be a blower. The air pipe 171 provides a gas flow channel, and a one-way valve is arranged in the air pipe 171 to prevent water from flowing back. When the air pipe 171 arranged at the bottom of the pre-washing tank 15 exhausts air into the water body, the gas stirs the water body to churn, so that the uppermost layer of water in the pre-washing tank 15 entrains floating objects and overflows to the filter tank 16.

[0103] The first floating object discharge channel 18 is arranged in the filter tank 16. The first floating object discharge channel 18 is provided with an overflow port 182. The setting height of the overflow port 182 is higher than the bottom surface of the filter tank 16. Furthermore, a filter screen is provided at the open portion of the filter tank 16. The water and floating objects overflowing from the pre-wash tank 15 into the filter tank 16 are filtered through the filter screen, and slightly larger particles are intercepted. What enters the cavity of the filter tank 16 is mainly water and oil. As the water level in the filter tank 16 reaches the overflow port position, the oil is discharged from the overflow port, and the water in the filter tank 16 is purified.

[0104] The recycling system 19 includes a first recycling water pipe 191, one end of which is connected to the filter tank 16 and the other end of which is connected to the pre-wash tank 15, and a pumping device 192 for conveying water in the first recycling water pipe 191. The pumping device 192 of this embodiment is a circulating water pump. The function of the first recycling water pipe 191 is to convey the purified water in the filter tank 16 to the pre-wash tank 15 for recycling, so that under the same water volume, the water utilization time is greatly extended, the utilization rate is improved, and water resources are saved.

[0105] In a specific embodiment, the filter tank 16 is provided with a drain port, and the first floating object discharge channel 18 includes a pipe body 181. The overflow port 182 is provided on the pipe body 181 and communicates with the inner cavity of the pipe body 181. The lower end of the pipe body 181 is sealed and connected to the drain port of the filter tank 16. Further, a second floating object discharge channel 20 is provided at the drain port of the pre-wash tank 15. The second floating object discharge channel 20 has the same structure as the first floating object discharge channel 18. The arrangement method at the drain port is the same. A filter screen is arranged around the second floating object discharge channel 20. The so-called sealed connection means that there is a good sealing relationship after the lower end of the pipe body 181 is connected to the drain port, and water will not leak from the connection. The connection between the lower end of the pipe body 181 and the drain port can be detachable or fixed. This embodiment preferably has a detachable connection method. When it is necessary to quickly discharge the water in the filter tank 16, the pipe body 181 is removed and the water can be discharged from the drain port. The purpose of arranging the filter screen around the second floating object discharge channel 20 is to prevent large particles from entering the overflow port and blocking the discharge channel.

[0106] A filter screen is provided at the connection between the filter tank 16 and the first water recovery pipe 191. A filter screen is provided at the connection between the pre-wash tank 15 and the first water recovery pipe 191.

[0107] A feasible embodiment is that a device chamber 151 is sunken in the pre-wash tank 15, a heating element is arranged in the device chamber 151, the top opening of the device chamber 151 is flush with the bottom of the pre-wash tank 15, and a filter is arranged at the top opening of the device chamber 151. The purpose of providing the heating element is to heat the water in the pre-wash tank to a desired temperature for use according to usage requirements.

[0108] The above describes the water purification and recycling function of the pre-washing equipment itself. The following describes the function of the pre-washing equipment that can be cleaned without a cleaning agent after the influent water has been treated.

[0109] A feasible embodiment is that the pre-washing equipment also includes a first water treatment system arranged in the pre-washing tank 151 area and supplying water to the pre-washing tank 151, wherein the first water treatment system includes a water weak alkalization module 2, a first water magnetization module 3 that can magnetize water to form small molecular cluster water with a half-width less than 60HZ, and a water flow channel 1. Half-width is a key detection indicator of small molecular cluster water, which directly reflects the compactness of water molecular clusters. Mainly relying on nuclear magnetic resonance (NMR), 17O-NMR technology qualitatively determines the size of water molecular clusters. By measuring the half-width of the vibration frequency of water, the size of the water molecular cluster can be known. The smaller the HZ value, the smaller the water molecular cluster.

[0110] The water weak alkalinization module 2 comprises a housing 21 with a water inlet and a water outlet, and a filter material that can make water weakly alkaline and is encapsulated in the housing 21. The filter material can make water weakly alkaline by physical means, which is a prior art. There are many filter materials that can make water weakly alkaline by physical means in the prior art. This embodiment uses medical stone, tourmaline, ochre, hexacyclic stone, calcium sulfite and nano zeolite uniformly mixed as the filter material.

[0111] 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 21 of the water weak alkalization module 2 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 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.

[0112] 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 first tube 31 area. The first tube 31 has a water inlet and a water outlet; the water flow channel 1 includes a water inlet and a water outlet. A feasible 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 poles of the two magnets are opposite. The magnetic field magnetic force parameter between the two magnets is 5000-6000 Gauss. Preferably 5500 Gauss. When there are multiple magnet groups, the arrangement of adjacent magnet groups is such that the positive 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.

[0113] 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.

[0114] 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.

[0115] The rare earth filler is an existing technology, 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.

[0116] 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 .

[0117] A feasible embodiment is that the water inlet of the water weak alkalization module 2 is connected to the water flow channel 1. 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. In this embodiment, the water is first weakly alkalized and then magnetized. For the pre-washing stage, it can be rinsed with small molecular cluster water without adding a cleaning agent.

[0118] Further, a feasible embodiment is that the first water treatment system also includes an ozone generating module 4 and a static mixer 6. The ozone generating module 4 includes an ozone generator, 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 2 and the water inlet of the first tube 31 of the first water magnetization module 3. The static mixer 6 has a water inlet and a water outlet, and 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 can be connected to the open area of ​​the pre-wash tank 15. In the above further improved embodiment, the water treatment sequence is water weak alkalization-ozone-magnetization.

[0119] Another feasible embodiment is that the first water treatment system also includes an ozone generating module 4 and a static mixer 6. The ozone generating module 4 includes an ozone generator, 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 first pipe water outlet 31 of the first water magnetization module 3 and the water outlet of the water flow channel 1. The static mixer 6 has a water inlet and a water outlet. The water inlet of the static mixer 6 is connected to the water outlet of the water flow channel. The water outlet of the static mixer 6 can be connected to the open area of ​​the pre-wash tank 15. The water treatment sequence of this scheme is weak alkalization of water - magnetization - ozone. Figure 3 As shown, based on this embodiment, it can be further implemented as follows: at least one second water magnetization module ( Figure 3 The second water magnetization module has the same structure as the first water magnetization module 3. The first water inlet of the second water magnetization module is connected to the water outlet of the first water magnetization module 3. The first water outlet of the second water magnetization module is connected to the water flow channel 1. The water treatment sequence of this scheme is weak alkalinization of water - multi-stage magnetization - ozone. In the field of tableware washing, considering the comprehensive cost and effect, this scheme can be preferred as the scheme of the dishwasher.

[0120] The ozone generating module 4 is a prior art, and its main purpose is to generate ozone, and it is sufficient to pass the ozone into the water flow channel. The static mixer 6 is also an existing part. The purpose of setting the static mixer 6 is to make ozone and water fully mixed, so as to facilitate the sterilization and decontamination capabilities.

[0121] In order to achieve a stronger magnetization effect and make the water form the smallest possible molecular clusters, more levels of water magnetization modules can be connected before and / or after the access point of the ozone delivery pipe, and can be flexibly selected according to different application scenarios and needs. For example, in the field of dishwashing, one or two levels of magnetization in the pre-wash stage can basically meet the requirements.

[0122] Generally, a faucet 111 is connected to the water outlet of the static mixer 6 to control the discharge of water into the pre-wash tank 15 .

[0123] The function of the first water treatment system is: after the tap water enters the water flow channel 1, it is treated by the water weak alkalization module 2 to make the water weakly alkaline, and then the water is magnetized by the primary or multi-stage magnetization of the water magnetization module 3 to form small molecular water, and after being evenly mixed with ozone, it forms weak alkaline water that can sterilize and disinfect and has strong permeability. In this process, the dipole moments of the two HO bonds of the water molecule cannot be offset, the positive and negative charge centers do not overlap, and the entire molecule has a higher polarity. By using the polarity of the water molecule and the positive and negative charges of the oil stain to form an attraction principle, the water molecule can easily carry away the oil stain, thus achieving the purpose of cleaning the stain without a detergent.

[0124] When the pre-washing device is in use, the first pool water needs to be passed through the first water treatment system through tap water for treatment and then put into the pre-washing tank 15. In the subsequent use, the water is recycled by self-purification for pre-washing, and there is no need to obtain water from the first water treatment system. Of course, if water loss occurs during the pre-washing process, or the magnetization is reduced due to the large number of cycles of water use, water can be replenished from the first water treatment system into the pre-washing tank according to demand.

[0129] The recovery system 19 further includes a second recovery water pipe 193. One end of the second recovery water pipe 193 is connected to the filter tank 16, and the other end is connected to the drainage system 7.

[0130] Since this embodiment is the main wash stage, the requirements for the water treatment system will be higher, and there are also requirements for the drying speed after rinsing. Therefore, the water treatment sequence of weak alkalization of water-one or multiple levels of magnetization-ozone-magnetization (one or multiple levels) is selected to make the half width of the formed small molecular cluster water as small as possible, for example, about 40HZ. The second water treatment system structure includes a water weak alkalization module 2, a second water magnetization module 5, a water flow channel 1, an ozone generation module 4, a first water magnetization module 3, and a static mixer 6. The second water magnetization module 5 has the same structure as the first water magnetization module 3.

[0131] The water weak alkalization module 2 includes 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 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 first tube 31 area. The first tube 31 has a water inlet and a water outlet. The water flow channel 1 includes a water inlet and a water outlet. 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. The water inlet of the water weak alkalization module 2 is connected to the water flow channel 1. 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 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. At least one second water magnetization module 5 is also provided between the water outlet of the water weak alkalization module 2 and the delivery pipe access point of the ozone generating module 4. The water inlet of the first pipe 31 of the second water magnetization module 5 is communicated with the water outlet of the water weak alkalization module 2. The water outlet of the first pipe 31 of the second water magnetization module 5 is communicated with the water inlet of the first pipe 31 of the first water magnetization module 3. 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 washing system.

[0133] A feasible embodiment is that 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. 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.

[0134] Furthermore, 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 area of ​​the water collecting portion 10 and arranged opposite to the first spray device 81 .

[0135] The water storage tank 91 is connected to the first spray device 81 and the second spray device 82 through pipelines.

[0136] The water collecting part 10 is connected to the first spraying device 81 and the second spraying device 82 through pipelines.

[0137] The water delivery module 9 further includes a delivery pipeline 95 which can deliver water from the water storage tank 91 to the water collecting part 10 .

[0138] The water delivery module 9 further includes a first pump 93 for pumping water from the water storage tank 91 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.

[0139] 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.

[0140] 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 are enclosed to 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 storage 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. In the washing room 14 area, a conveying pipeline outlet is opened on the side wall of the frame 11 located above the water collecting part 10, and water is sent from the water storage tank 91 to the water collecting part 10 through the outlet. This water circuit 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 a variable frequency pump is selected for the first pump 93, so that water supply for the flushing device 8 and the water collecting part 10 can be achieved.

[0141] 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.

[0142] The working process of the cleaning system of this embodiment is as follows:

[0143] (1) Pre-washing stage: The articles to be washed are placed in the pre-washing tank. The water from the first water treatment system enters the pre-washing tank 15 and reaches the preset liquid level. The heating element is activated to control the water temperature in the pre-washing tank as needed. The stirring device 17 is activated to make the water tumble. During the tumbling process, the large particles of residue and some stains on the articles to be washed are washed into the pre-washing tank 15. When the uppermost part of the water in the pre-washing tank 15 overflows into the filter tank 16, most of the oil stains enter the filter tank 16 with the overflow water. When the water in the filter tank 16 rises to a certain height, the oil stains in the filter tank 16 are discharged through the overflow port 182 of the first floating object discharge channel 18. The water in the filter tank 16 becomes slightly cleaner water that can meet the needs of pre-washing, and flows back to the pre-washing tank through the first recovery water pipe 191 for reuse. A small part of the oil stains is discharged through the overflow port of the second floating object discharge channel 20.

[0144] In the pre-washing stage, in addition to the function of self-purification and water recycling, the equipment of this embodiment is provided with a first water treatment system, a water weak alkalization module cooperates with a water magnetization module, and the magnetization program is set after the weak alkalization program. The water obtained is a small molecular cluster water as small as possible, and the small molecular cluster water can easily carry away the oil and dirt. Therefore, the pre-washing stage can be pre-washed without a cleaning agent. On the one hand, water is saved as much as possible, and on the other hand, no sewage with chemical agents is discharged.

[0145] (2) The main wash stage is realized by the function of the main washing machine. The water passing through the second water treatment system enters the water storage tank 91. The first pump 93 presses the hot water in the water storage tank 91 into the outlet of the side wall of the frame 11 through the delivery pipeline 95. The water enters the water collection part 10 and is further heated. The water in the water collection part 10 is pumped into the first spray device 81 and the second spray device 82 by the second pump 94 installed at the bottom of the water collection part 10 to wash the items. While washing, the water is drained from the drainage system 7, and clean water continuously flows into the water collection part 10. The water discharged by the drainage system 7 is discharged into the filter pool 16 through the second recovery water pipe 193. After the filter pool 16 performs its self-purification function, it flows back to the pre-wash pool 15 through the first recovery water pipe 191 for reuse.

[0146] In the main wash stage, the second water treatment system is set up, which has the same function as the first water treatment system, and can remove stains through magnetized small molecular water without adding detergent. In addition, the wastewater discharged in the main wash stage flows into the pre-wash equipment for recycling and pre-washing, saving water resources.

[0147] (3) The rinsing stage is realized by the function of the main washing machine. After the main washing 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 storage tank 91 through the pipe to the first spray device 81 and the second spray device 82 for rinsing. The rinsing water enters the water storage tank 91 through the return pipe 92 for recycling and can be used for rinsing and main washing.

[0148] In the rinsing stage, since no detergent is used, the water in the rinsing stage is not polluted and is very clean. After being recycled and reused, no water is wasted and discharged, and the total water consumption is greatly reduced, saving water resources. In addition, since the water used is magnetized small molecular cluster water, it is more volatile, and the rinsed items are not easy to bead, and the washed items will dry quickly, and drying measures such as drying agents and / or drying modules can be omitted.
