Description

Technical Field

[0001] This utility model belongs to the field of dirt cleaning technology, specifically relating to a pre-washing device and cleaning system, which is applicable to most scenarios that require cleaning stains and oil, especially tableware cleaning. Background Technology

[0002] In various industries, including industrial production, daily life, and healthcare, there are scenarios where cleaning is necessary. Examples include cleaning tobacco tar, household or commercial tableware, medical supplies, oil tanks, and toilets. Cleaning methods mainly include a main wash, a rinsing stage, and a drying stage. The main wash stage involves adding cleaning agents to remove stubborn stains such as oil, blood, and urine scale. Because of the added cleaning agents, a specialized rinsing device is needed to remove the bubbles produced by the cleaning agents.

[0003] To ensure thorough cleaning and improve efficiency, a pre-wash is often performed before the main wash stage. Therefore, pre-wash equipment is often used in conjunction with the main wash equipment in many applications. In developing this invention, it was discovered that the existing technology has at least the following problems:

[0004] 1. The pre-washing stage requires a large amount of water. The water in the pre-washing tank becomes very dirty quickly after the equipment has been running for a short time. Workers then drain the wastewater as needed, replenish it with fresh water, and begin the next round of pre-washing. Therefore, the pre-washing stage involves a large volume of water discharge and demand, resulting in significant water waste.

[0005] 2. No matter how you rinse after using a cleaning agent, there will always be cleaning agent residue. Any residue can cause harm. For example, in dishwashing, using tableware with chemical residue can harm your health; in laundry, clothing with chemical residue may cause skin allergies or skin diseases.

[0006] 3. After cleaning with cleaning agents, the discharged agents can cause soil compaction, and the seepage of the cleaning agents can also lead to groundwater pollution, severely damaging the living environment. Treating the cleaning agents at the discharge point would require specialized environmental protection equipment, inevitably resulting in additional expenses and increasing the cost of cleaning.

[0007] 4. In some cleaning scenarios where items need to be dried, a dedicated drying module is required, such as for dishwashing. Some drying methods are integrated into the washing system's hot air system, used to dry items after the main wash and rinse stages; others are independent drying devices that transfer cleaned items to the device for air drying or baking. In many cases, drying agents are added to achieve rapid drying. These methods have the following problems: (a) After drying with a drying agent, the agent forms a persistent film on the surface of the item. The drying agent is more harmful to the human body than the cleaning agent. In applications such as dishwashing, when people use the tableware, some of the drying agent will inevitably enter the body along with the food, causing harm. (b) Drying equipment is expensive, increasing the overall equipment production cost.

[0008] 5. Due to the addition of detergents, the wastewater generated in both the main wash and rinsing stages contains chemicals and is essentially unrecyclable. Most cleaning equipment discharges this wastewater directly into the environment, causing pollution. In some cleaning scenarios, such as dishwashers, the wastewater can be partially recycled. Current dishwasher technology utilizes wastewater by recycling the detergent-containing wastewater to the pre-wash stage, as this stage also requires the addition of detergents for initial washing of large particles of dirt.

[0009] Regardless of how wastewater is utilized in existing technologies, the water volume used in the main wash and rinsing stages remains unchanged, as both stages require clean water. The washing machines consume a massive amount of water; current equipment uses at least 5 liters per minute in the main wash and rinsing stages, meaning at least 5 liters of wastewater are discharged per minute. This large volume of water is sent to the pre-wash stage, which cannot utilize it all. Therefore, current operations typically recycle water from the rinsing stage for use in the pre-wash stage, while the dirtier water from the main wash stage is discharged directly. In summary, existing technologies consume a huge amount of water in the main wash and rinsing stages, and current recycling methods cannot change this problem. Utility Model Content

[0010] To address the aforementioned problems, this utility model aims to provide a pre-washing device that can improve water utilization and save water resources.

[0011] The technical solution to the problem solved by this utility model is: a pre-washing device, comprising:

[0012] A pre-washing tank is suitable for holding items to be washed. The pre-washing tank is equipped with a drain outlet and has an open top.

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

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

[0015] The first floating debris discharge channel is located inside the filter tank. The first floating debris discharge channel is equipped with an overflow port, and the overflow port is located at a height higher than the bottom surface of the filter tank.

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

[0017] In the above scheme, water washes the dirt from the object to be cleaned into the pre-wash tank. Heavier items sink, while oil and other contaminants float on the surface. Most of the oil overflows into the filtration tank. Once the water level in the filtration tank reaches a certain height, the oil is drained through the overflow outlet of the first floating debris discharge channel. The water in the filtration tank becomes slightly cleaner and suitable for pre-washing, then flows back into the pre-wash tank for reuse through the first recycling pipe. This scheme significantly extends the water utilization time and improves the utilization rate, thus conserving water resources, given the same amount of water.

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

[0019] Furthermore, a filter screen is provided at the opening of the filtration pool.

[0020] One specific implementation is that the agitation device includes an air pipe installed in the pre-washing tank and an air supply device installed outside the pre-washing tank and connected to the air pipe, wherein the air pipe is provided with a plurality of air holes.

[0021] One feasible implementation is that a device chamber is submerged in the pre-washing tank, a heating element is installed in the device chamber, the top opening of the device chamber is flush with the bottom of the pre-washing tank, and a filter screen is installed at the top opening of the device chamber.

[0022] Furthermore, a second floating debris discharge channel is provided at the drain outlet of the pre-washing tank. The second floating debris discharge channel has the same structure as the first floating debris discharge channel and is set in the same way at the drain outlet. A filter screen is provided around the second floating debris discharge channel.

[0023] One feasible implementation scheme further includes a first water treatment system located in the pre-washing tank area to supply water to the pre-washing tank. The first water treatment system includes a water weak alkalization module, a first water magnetization module that can magnetize water to form small molecular clusters of water with a half-width of less than 60 Hz, and a water flow channel.

[0024] The water alkalinization module includes a housing with an inlet and an outlet, and a filter media encapsulated within the housing that can turn water into a weak alkaline state; the first water magnetization module includes a first tube with magnetic conductivity, and a magnet disposed on the first tube to form a magnetic field in the region of the first tube, the first tube having an inlet and an outlet; the water flow channel includes an inlet and an outlet.

[0025] The water weak alkalization module and the first water magnetization module are sequentially arranged between the inlet and outlet of the water flow channel along the water flow direction.

[0026] The inlet of the water weak alkalization module is connected to the water flow channel, the outlet of the water weak alkalization module is connected to the inlet of the first tube of the first water magnetization module, and the outlet of the first tube of the first water magnetization module is connected to the outlet of the water flow channel.

[0027] In the above technical solution, the main function of the water weak alkalization module is to make the water weakly alkaline, and the main function of the first water magnetization module is to magnetize the water to form small water molecule clusters. During the process of water passing through the water weak alkalization module and the first water magnetization module, the dipole moments of the two H1O bonds of the water molecules cannot cancel each other out, the centers of positive and negative charges do not coincide, and the entire molecule has high polarity. Utilizing the principle of attraction between the polarity of water molecules and the positive and negative charges of oil stains, the water molecules easily trap and carry away the oil stains (because there is no emulsification reaction), thus achieving the purpose of cleaning stains without detergent.

[0028] Setting the magnetization program after the weak alkalinity program results in water with the smallest possible molecular clusters. This allows the water to penetrate more effectively during the cleaning process, better encapsulating the dirt and thus cleaning it thoroughly.

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

[0030] The ozone generating module includes an ozone generator and a delivery pipe connected to the ozone generator and supplying ozone into the water flow channel; the connection point of the delivery pipe is located between the outlet of the water weak alkalization module and the inlet of the first pipe of the first water magnetization module.

[0031] The static mixer has an inlet and an outlet. The inlet of the static mixer is connected to the outlet of the water flow channel, and the outlet of the static mixer can be connected to the open area of ​​the pre-washing tank.

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

[0033] The ozone generator module serves two main purposes: first, sterilization and disinfection; second, ozone, being a strong oxidant, possesses a certain degree of cleaning ability, allowing it to work more effectively with small water molecule clusters during the cleaning process to remove stains. The static mixer is installed to ensure thorough mixing of ozone and water, facilitating the effective sterilization, disinfection, and cleaning.

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

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

[0036] The static mixer has an inlet and an outlet. The inlet of the static mixer is connected to the outlet of the water flow channel, and the outlet of the static mixer can be connected to the open area of ​​the pre-washing tank.

[0037] The water treatment sequence for this scheme is: weak alkalization of water – magnetization – ozone introduction.

[0038] Furthermore, at least one second water magnetization module is provided between the outlet of the first water magnetization module and the inlet of the ozone generating module. The second water magnetization module has the same structure as the first water magnetization module.

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

[0040] The water treatment sequence of this scheme is: weak alkalization of water – multi-stage magnetization – ozone introduction.

[0041] One feasible implementation 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 to each other;

[0042] The magnetic field between the two magnets has a magnetic force of 5000-6000 Gauss;

[0043] When there are multiple magnet groups, the arrangement of adjacent magnet groups is such that their orthogonal 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 sealed cavity, the first tube passing through the sealed cavity of the shell, the sealed cavity being filled with rare earth filler having thermal conductivity and magnetic locking properties, and a heating component and a sensor for monitoring temperature being provided in the area surrounding the first tube.

[0045] Accordingly, in order to solve the problem of water waste in the main washing stage, this utility model also provides a cleaning system, including: a main washing machine, and the above-mentioned pre-washing equipment;

[0046] The main washing machine includes a washing system suitable for rinsing dirt, a drainage system connected to the washing system, and a second water treatment system that can treat water to a half-width of less than 60 Hz, the second water treatment system being connected to the washing system;

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

[0048] The recycling system also includes a second recycling 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 from the main wash stage can be discharged to the filter tank through the second recovery water pipe, while floating matter such as oil is discharged through the first floating matter discharge channel. The water from the main wash stage, after purification, can then be sent to the pre-wash tank for pre-washing through the first recovery water pipe, ensuring that water from the main wash stage is not discharged externally and increasing the water utilization rate of the main wash stage. Furthermore, the combined application of the second and first water treatment systems in the above scheme eliminates the need to add cleaning agents during the pre-wash and main wash stages.

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

[0051] The ozone generating module includes an ozone generator and a delivery pipe connected to the ozone generator and supplying ozone into the water flow channel; the connection point of the delivery pipe is located between the outlet of the water weak alkalization module and the inlet of the first pipe of the first water magnetization module.

[0052] At least one second water magnetization module is provided between the outlet of the water weak alkalization module and the inlet of the ozone generation module. The second water magnetization module has the same structure as the first water magnetization module.

[0053] The inlet of the first pipe of the second water magnetization module is connected to the outlet of the weakly alkaline water module, and the outlet of the first pipe of the second water magnetization module is connected to the inlet of the first pipe of the first water magnetization module.

[0054] The water treatment sequence of this scheme is: weak alkalization of water — primary or multiple stages of magnetization — ozone introduction — magnetization.

[0055] In one feasible implementation, the washing system includes a rinsing device for rinsing off dirt, a water supply module for supplying water to the rinsing device, and a water collection section for receiving water.

[0056] The water supply module includes a water storage tank connected to the outlet of the water flow channel, and the water storage tank is connected to the flushing device through a pipe;

[0057] The water collection section is connected to the drainage system, and the water collection section or the drainage system is connected to a return water pipe. The return water pipe is connected to the water storage tank, and valves are provided on both the drainage system and the return water pipe.

[0058] In the above solution, since no detergent is used, the water used in the rinsing stage remains clean and uncontaminated. The rinsing water is recycled to a storage tank via a return pipe and can be used for both rinsing and the main wash. This ensures that no water is wasted during the rinsing stage, significantly reducing total water consumption and conserving water resources.

[0059] Furthermore, the rinsing device includes a first spray device disposed above the water collection section and a second spray device disposed in the water collection section 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 via pipes respectively;

[0061] The water collection unit is connected to the first spray device and the second spray device respectively through pipes;

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

[0063] Furthermore, it also includes a rack, a storage rack, and a protective cover connected to the rack and capable of being opened, wherein the rack includes an equipment room located at the bottom; the water supply module, water treatment system, and drainage system are located in the equipment room;

[0064] The water collection unit is located above the equipment room, and the water receiving surface of the water collection unit and the protective cover together form a washing room; the water collection unit is equipped with a first heating element for heating water; the water storage tank is equipped with a second heating element for heating water;

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

[0066] The significant advantages of this invention are:

[0067] 1. The design of the recycling system enables the pre-washing equipment to independently recycle water, which significantly extends the water utilization time and improves the utilization rate under the same water volume, thus saving water resources.

[0068] 2. After the pre-washing equipment is installed in the first water treatment system, the water weak alkalization module works in conjunction with the water magnetization module, and the magnetization program is set after the weak alkalization program. The resulting water is water with the smallest possible molecular clusters. Small molecular clusters of water can easily carry away oil stains, achieving the purpose of pre-washing without the need for cleaning agents.

[0069] 3. The dirty water generated during the main wash stage can be discharged to the pre-wash equipment through the second recycling water pipe. After being purified by the pre-wash equipment, it is used for pre-washing, thus ensuring that the water from the main wash stage is not discharged externally, increasing the water utilization rate of the main wash stage and saving water resources.

[0070] 4. The design of the second water treatment system ensures that the main washing machine uses small-molecule cluster water, which easily carries away oil and dirt, achieving the goal of cleaning stains without detergent. Simultaneously, the smaller the water molecule cluster, the easier it evaporates, the less water droplets remain on the rinsed items, and the faster they dry, achieving rapid natural drying. Due to its rapid natural drying characteristic, drying agents and / or drying modules can be omitted.

[0071] 5. Since no detergent is needed, no bubbles are produced, which can greatly shorten rinsing time and improve cleaning efficiency.

[0072] 6. For the main wash machine itself, the rinsing water is recycled back to the storage tank via the return water pipe and can be used for both rinsing and the main wash. This ensures that no water is wasted during the rinsing stage, significantly reducing total water consumption and saving water resources.

[0073] As can be seen from the above description of the effects, 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 storage tank for the main wash and rinsing, and the rinsing water is used for the main wash and then enters the pre-wash. In terms of rinsing water alone, it undergoes a cycle of rinsing, main wash, and pre-wash; the pre-wash stage not only utilizes the main wash water but also has the ability to self-purify, recycle, and reuse. From pre-wash to main wash and then to rinsing, the water is fully utilized multiple times, greatly improving water utilization efficiency and reducing the total water consumption of the cleaning process.

[0097] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0098] For ease of description, the relative positions of the components (e.g., top, bottom, left, right, etc.) are described according to the layout orientation of the accompanying drawings and do not limit the structure of this patent. Example 1

[0099] Figures 1-6 An embodiment of the present invention and its variants are shown. A pre-washing device includes a pre-washing tank 15, a filter tank 16, an agitator 17, a first floating matter discharge channel 18, and a recycling system 19.

[0100] The pre-wash tank 15 is suitable for holding items to be washed. The pre-wash tank 15 is provided with a drain outlet. The top of the pre-wash tank is open.

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

[0102] The agitation device 17 is installed inside the pre-wash tank 15 and is suitable for agitating the water in the pre-wash tank 15 into a vortex and / or turbulent flow. The purpose of the agitation device 17 is to remove large particles of residue from the items to be washed. The agitation device 17 is existing technology and has various structural forms, such as impeller agitation and bubble agitation. In a specific feasible embodiment, the agitation device 17 includes an air pipe 171 installed inside the pre-wash tank 15 and an air supply device 172 installed outside the pre-wash tank 15 and connected to the air pipe 171. The air pipe is provided with several air holes 173. The air supply device 172 can be a blower. The air pipe 171 provides a gas flow channel, and a one-way valve is installed inside the air pipe 171 to prevent water backflow. When the air pipe 171 installed at the bottom of the pre-wash tank 15 exhausts gas into the water, the gas agitates the water, causing the water at the top of the pre-wash tank 15 to overflow with floating matter into the filter tank 16.

[0103] The first floating debris discharge channel 18 is located within the filter tank 16. The first floating debris discharge channel 18 is equipped with an overflow port 182. The overflow port 182 is positioned higher than the bottom surface of the filter tank 16. Furthermore, a filter screen is installed at the opening of the filter tank 16. Water and floating debris overflowing from the pre-wash tank 15 into the filter tank 16 are filtered by the filter screen; larger particles are intercepted, and the main components entering the filter tank 16 are water and oil. As the water level in the filter tank 16 reaches the overflow port, the oil is discharged from the overflow port, thus purifying the water in the filter tank 16.

[0104] The recycling system 19 includes a first recycling water pipe 191 connected at one end to the filter tank 16 and at the other end to the pre-wash tank 15, and a pumping device 192 for transporting water in the first recycling water pipe 191. In this embodiment, the pumping device 192 is a circulating water pump. The function of the first recycling water pipe 191 is to send the purified water from the filter tank 16 into the pre-wash tank 15 for recycling, thereby significantly extending the water utilization time and improving the utilization rate under the same water volume, thus saving water resources.

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

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

[0107] One feasible embodiment is that a device chamber 151 is sunken within the pre-wash tank 15, and a heating element is installed inside 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 screen is installed at the top opening of the device chamber 151. The purpose of installing the heating element is to heat the water in the pre-wash tank to the required temperature according to usage needs.

[0108] The above describes the water purification and recycling function of the pre-wash equipment itself. The following describes the function of the pre-wash equipment so that the incoming water can be treated and cleaned without detergent.

[0109] One feasible embodiment includes a pre-washing device that further comprises a first water treatment system located in the pre-washing tank 151 area to supply water to the pre-washing tank 151. 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 water molecule clusters with a half-width of less than 60 Hz, and a water flow channel 1. The half-width is a key detection indicator for small water molecule clusters, directly reflecting the compactness of the water molecule clusters. Qualitative determination of water molecule cluster size is mainly achieved using nuclear magnetic resonance (NMR), specifically 17O-NMR technology. By measuring the half-width of the water's vibrational frequency, the size of the water molecule clusters can be determined. The smaller the Hz value, the smaller the water molecule clusters.

[0110] The water alkalinization module 2 includes a housing 21 with an inlet and an outlet, and a filter media encapsulated within the housing that can turn water into a weakly alkaline state. The filter media turns water into a weakly alkaline state through a physical means, which is existing technology. Various filter media exist that can physically turn water into a weakly alkaline state; in this embodiment, a uniform mixture of maifanite, tourmaline, ochre, hexagonal quartz, calcium sulfite, and nano-zeolite is used as the filter media.

[0111] Depending on the volume of water to be treated, the housing 21 can be designed in different forms. For example, in a small-volume water treatment scenario, one specific embodiment may have the housing 21 of the water weak alkalization module 2 including a chamber in which the filter media is encapsulated. In a large-volume water treatment scenario, one specific embodiment may have the housing of the water weak alkalization module 2 including several adjacent or separate chambers, which are sequentially connected, and the filter media is encapsulated in different chambers. This allows for an increase in the amount of filter media, thereby increasing the treatment capacity.

[0112] The first water magnetization module 3 includes a first tube 31 with magnetic conductivity and a magnet 32 ​​disposed on the first tube 31 to form a magnetic field in the region of the first tube 31. The first tube 31 has an inlet and an outlet; the water flow channel 1 also includes an inlet and an outlet. In one feasible embodiment, 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 magnets are fixedly disposed on the outer surface of the first tube 31, and the opposite magnetic poles of the two magnets face each other. The magnetic force parameter between the two magnets is 5000-6000 Gauss, preferably 5500 Gauss. When multiple magnet groups are provided, the arrangement of adjacent magnet groups is such that their orthogonal projections in the axial direction of the first tube 31 are perpendicular to each other. In another feasible embodiment, the distance between the opposite magnetic poles of the two magnets is 4-6 mm to ensure sufficient magnetic field strength.

[0113] One feasible embodiment involves encasing each magnet assembly with a magnetic locking element 33 to prevent magnetic leakage. The magnetic locking element 33 is a cylindrical iron block. A hole matching the size of the magnet assembly is opened in the center of the iron block, and the magnet assembly fits into this hole. Due to the encasing effect of the iron block, the magnetic field generated by the magnet assembly will not leak, further improving the magnetization effect.

[0114] Furthermore, the first water magnetization module 3 also includes a housing 34 with a sealed cavity. The first tube 31 passes through the sealed cavity of the housing 34. The sealed cavity is filled with a rare earth filler that has thermal conductivity and magnetic locking properties. A heating element 36 and a temperature sensor 35 are provided around the first tube 31. The heating element 36 is provided around the first tube 31, meaning that the position of the heating element 36 can be adjusted according to the actual design. It can be placed inside the sealed cavity or on the housing 34, as long as the required temperature can be maintained. In this embodiment, the heating element 36 is placed inside the sealed cavity, and the temperature sensor is placed on the housing.

[0115] The rare earth filler is a prior art material, including at least one of graphene powder, tourmaline powder, bian stone powder, germanium powder, biochar powder, maifan 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 inlet and outlet of the water flow channel 1 along the water flow direction.

[0117] In one feasible embodiment, the inlet of the water weak alkalization module 2 is connected to the water flow channel 1. The outlet of the water weak alkalization module 2 is connected to the inlet of the first pipe 31 of the first water magnetization module 3. The outlet of the first pipe 31 of the first water magnetization module 3 is connected to the 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 is already possible to achieve rinsing with small molecule cluster water without adding cleaning agents.

[0118] Furthermore, in a feasible embodiment, the first water treatment system further includes an ozone generating module 4 and a static mixer 6. The ozone generating module 4 includes an ozone generator and a delivery pipe connected to the ozone generator and supplying ozone into the water flow channel. The connection point of the delivery pipe is located between the outlet of the water weak alkalization module 2 and the inlet of the first pipe 31 of the first water magnetization module 3. The static mixer 6 has an inlet and an outlet, with the inlet of the static mixer 6 connected to the outlet of the water flow channel 1. The 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 supply—magnetization.

[0119] Another feasible embodiment includes an ozone generating module 4 and a static mixer 6 in the first water treatment system. The ozone generating module 4 includes an ozone generator and a delivery pipe connected to the ozone generator and supplying ozone into the water flow channel. The connection point of the delivery pipe is located between the first outlet 31 of the first water magnetization module 3 and the outlet of the water flow channel 1. The static mixer 6 has an inlet and an outlet. The inlet of the static mixer 6 is connected to the outlet of the water flow channel. The outlet of the static mixer 6 can be connected to the open area of ​​the pre-wash tank 15. The water treatment sequence in this scheme is weak alkalization of water—magnetization—ozone supply. Figure 3 As shown, based on this embodiment, it can be further implemented by providing at least one second water magnetization module between the outlet of the first water magnetization module 3 and the connection point of the delivery pipe of the ozone generating module 4. Figure 3 (Not shown, but built into the housing of ozone generating module 4). The second water magnetization module has the same structure as the first water magnetization module 3. The inlet of the first pipe of the second water magnetization module is connected to the outlet of the first water magnetization module 3. The outlet of the first pipe of the second water magnetization module is connected to the water flow channel 1. The water treatment sequence of this scheme is weak alkalization of water—multi-stage magnetization—ozone introduction. Considering both cost and effectiveness, this scheme is preferred for dishwashers in the field of dishwashing.

[0120] Ozone generating module 4 is existing technology; its main purpose is to generate ozone, which can then be introduced into the water flow channel. Static mixer 6 is also an existing component. The purpose of static mixer 6 is to ensure thorough mixing of ozone and water, thereby facilitating its sterilization, disinfection, and decontamination capabilities.

[0121] To achieve a stronger magnetization effect and form water molecules into the smallest possible clusters, multiple stages of water magnetization modules can be connected before and / or after the ozone delivery pipe connection point, allowing for flexible selection based on different application scenarios and needs. For example, in the dishwashing field, one or two stages of magnetization are generally sufficient for the pre-wash stage.

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

[0123] The function of the first water treatment system is as follows: After tap water enters the water flow channel 1, it is treated by the water weak alkalization module 2 to make the water weakly alkaline. Then, it undergoes one or more stages of magnetization by the water magnetization module 3, which magnetizes the water into small molecular clusters. After being uniformly mixed with ozone, it forms weakly alkaline water with strong sterilization and disinfection properties and high permeability. In this process, the dipole moments of the two H1O bonds of the water molecules cannot cancel each other out, and the centers of positive and negative charges do not coincide. The entire molecule has high polarity. Utilizing the principle of attraction between the polarity of water molecules and the positive and negative charges of oil stains, the water molecules easily trap and carry away the oil stains, thus achieving the purpose of cleaning stains without detergent.

[0124] When using the pre-washing equipment, the first pool of water needs to be treated by the first water treatment system after being fed into the pre-washing tank 15. Subsequent uses rely on its own purified and recycled water for pre-washing, eliminating the need to obtain water from the first water treatment system. However, if water loss occurs during the pre-washing process, or if the magnetization decreases due to excessive water circulation, water can be replenished from the first water treatment system into the pre-washing tank as needed.

[0125] Example 2

[0126] like Figure 7-11 As shown, in order to solve the problem of water waste in the main washing stage, this embodiment provides a cleaning system, including a main washing machine and a pre-washing device as described in Embodiment 1.

[0127] The main washing machine includes a washing system suitable for rinsing dirt, a drainage system 7 connected to the washing system, and a second water treatment system capable of treating water to a half-width of less than 60 Hz (preferably 40-50 Hz). The second water treatment system is connected to the washing system.

[0128] The second water treatment system has the same structure, function and effect as the first water treatment system.

[0129] The recycling system 19 also includes a second recycling water pipe 193. One end of the second recycling 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 focuses on the main washing stage, the requirements for the water treatment system are higher, and the drying speed after rinsing is also critical. Therefore, a water treatment sequence of weak alkalization—one or more stages of magnetization—ozone generation—magnetization (one or more stages) is selected to minimize the half-width of the formed small molecule clusters of water, for example, to around 40 Hz. The second water treatment system structure includes a 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 alkalinization module 2 includes a housing 21 with an inlet and an outlet, and a filter media encapsulated within the housing 21 that makes the water weakly alkaline. The first water magnetization module 3 includes a first tube 31 with magnetic conductivity and a magnet 32 ​​disposed on the first tube 31 to form a magnetic field in the region of the first tube 31. The first tube 31 has an inlet and an outlet. The water flow channel 1 includes an inlet and an outlet. The water alkalinization module 2 and the first water magnetization module 3 are sequentially arranged between the inlet and outlet of the water flow channel 1 along the water flow direction. The inlet of the water alkalinization module 2 is connected to the water flow channel 1. The outlet of the water alkalinization module 2 is connected to the inlet of the first tube 31 of the first water magnetization module 3. The outlet of the first tube 31 of the first water magnetization module is connected to the outlet of the water flow channel 1.

[0132] The ozone generating module 4 includes an ozone generator and a delivery pipe connected to the ozone generator and supplying ozone into the water flow channel. The connection point of the delivery pipe is located between the outlet of the water weak alkalization module 2 and the 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 outlet of the water weak alkalization module 2 and the connection point of the delivery pipe of the ozone generating module 4. The inlet of the first pipe 31 of the second water magnetization module 5 is connected to the outlet of the water weak alkalization module 2. The outlet of the first pipe 31 of the second water magnetization module 5 is connected to the inlet of the first pipe 31 of the first water magnetization module 3. The inlet of the static mixer 6 is connected to the outlet of the water flow channel 1. The outlet of the static mixer 6 is connected to the washing system.

[0133] One feasible embodiment includes a washing system comprising a rinsing device 8 for rinsing away dirt, a water supply module 9 for supplying water to the rinsing device 8, and a water collection section 10 for collecting water. The water supply module 9 includes a water storage tank 91 connected to the outlet of the water flow channel 1 (if a static mixer 6 is installed, the water storage tank 91 is connected to the outlet of the static mixer 6). The water storage tank 91 is connected to the rinsing device 8 via a pipe. The water collection section 10 is connected to a drainage system 7. A return water pipe 92 is connected to either the water collection section 10 or the drainage system 7. The return water pipe 92 is connected to the water storage tank 91. Valves are installed on both the drainage system 7 and the return water pipe. Since no detergent is used, the water used in the rinsing stage is not contaminated and remains clean. The rinsing water is recycled back to the water storage tank 91 via the return water pipe 92 for reuse in both rinsing and main washing. This ensures that no water is wasted during the rinsing stage, significantly reducing total water consumption and conserving water resources.

[0134] Furthermore, the rinsing device 8 includes a first spray device 81 disposed above the water collection section 10 and a second spray device 82 disposed in the area of ​​the water collection section 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 via pipes.

[0136] The water collection unit 10 is connected to the first spray device 81 and the second spray device 82 via pipes.

[0137] The water delivery module 9 also includes a delivery pipeline 95 that can deliver water from the water storage tank 91 to the water collection section 10.

[0138] The water supply module 9 also includes a first pump 93 that pumps 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 that pumps water from the water collection section 10 into the first spray device 81 and the second spray device 82 respectively.

[0139] Furthermore, it also includes a rack 11, a shelf, and a protective cover 12 connected to and operable by the rack 11. The rack 11 includes an equipment room 13 located at the bottom. The water supply module 9, the water treatment system, and the drainage system 7 are located in the equipment room 13.

[0140] The water collection section 10 is located above the equipment room 13. The water receiving surface of the water collection section 10 and the protective cover 12 together form the washing room 14. The water collection section 10 is equipped with a first heating element for heating the water. The water storage tank 91 is equipped with a second heating element for heating the water. The shelf is located in the area of ​​the water collection section 10 and between the first spray device 81 and the second spray device 82. In the washing room 14 area, a delivery pipe outlet is opened on the side wall of the frame 11 above the water collection section 10, and water is sent from the water storage tank 91 into the water collection section 10 through this outlet. This water path is for providing 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, instead of adding an additional water pump, a variable frequency pump is selected for the first pump 93, thereby enabling the supply of water to the rinsing device 8 and the water collection section 10.

[0141] The first heating element is used to heat the water in the water collection section 10, and the second heating element is used to heat the water in the water storage tank 91 to ensure the water temperature during the main wash and rinsing stages.

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

[0143] (1) Pre-washing stage: Items to be cleaned are placed in the pre-washing tank. Water from the first water treatment system enters the pre-washing tank 15 and reaches the preset liquid level. Heating elements are activated as needed to control the water temperature. The agitator 17 is activated to make the water churn. During the churning process, large particles and some stains on the items to be cleaned are washed into the pre-washing tank 15. As the water at the top of 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 matter discharge channel 18. The water in the filter tank 16 becomes slightly cleaner and suitable for pre-washing. It is then returned to the pre-washing tank for reuse through the first recycling water pipe 191. A small portion of the oil stains are discharged through the overflow port of the second floating matter discharge channel 20.

[0144] In the pre-washing stage, in addition to its self-purification and water recycling function, the equipment in this embodiment incorporates a first water treatment system. This system combines a weakly alkaline water module with a water magnetization module, and the magnetization process is set after the weakly alkaline water process. This results in water with the smallest possible molecular clusters. These small molecular clusters easily trap and carry away oil and dirt, thus eliminating the need for cleaning agents during the pre-washing stage. This approach saves water as much as possible and avoids the discharge of wastewater containing chemical agents.

[0145] (2) During the main wash stage, the main wash machine's function is used to deliver water from the second water treatment system into the storage tank 91. The first pump 93 pumps the hot water from the storage tank 91 through the delivery pipe 95 into the outlet on the side wall of the frame 11, where it enters the water collection section 10 and is further heated. The water in the water collection section 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 section 10 to clean the items. While washing, water is drained from the drainage system 7, and clean water continuously flows into the water collection section 10. The water discharged from the drainage system 7 is discharged into the filter tank 16 through the second recovery water pipe 193. After the filter tank 16 performs self-purification, it flows back to the pre-wash tank 15 through the first recovery water pipe 191 for reuse.

[0146] During the main wash stage, a second water treatment system, functioning similarly to the first, removes stains without the need for detergents by using magnetized water to form small molecular clusters. Furthermore, wastewater from the main wash stage is recycled into a pre-wash unit for pre-washing, conserving water resources.

[0147] (3) The rinsing stage is achieved by the function of the main washing machine. After the main washing stage is completed, the drainage system 7 is closed and the return water pipe is opened. The first pump 93 pumps the water in the water storage tank 91 through the pipeline 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 water pipe 92 for recycling and can be used for rinsing and main washing.

[0148] During the rinsing stage, since no detergent is used, the water used in this stage remains clean and uncontaminated. After recycling, the water is reused without any waste, significantly reducing total water consumption and conserving water resources. Furthermore, because the water used is magnetized small-molecule cluster water, it evaporates more easily, preventing water droplets from clinging to rinsed items and allowing for rapid drying, eliminating the need for drying agents and / or drying modules.
