Description

Technical Field

[0001] This utility model relates to the field of automatic cleaning technology, and more specifically, to a cleaning machine and a cleaning system. 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, and oil tanks. Cleaning methods mainly include a main wash stage, 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] A Chinese patent discloses a dishwasher comprising a dishwasher body, a detergent dispenser, and a water purifier. The dishwasher body has an inner cavity; the detergent dispenser is located outside the dishwasher body and connects to the inner cavity; the water purifier is located outside the dishwasher body and has an inlet and an outlet. The inlet is configured to connect to a tap water pipe, and the outlet connects to the inner cavity. However, this dishwasher requires the addition of detergent during cleaning to remove oil and dirt. After cleaning, the detergent is discharged with the wastewater, which can easily cause pollution. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that require the addition of additional cleaning fluid, and to provide a cleaning machine and cleaning system that can achieve the cleaning effect of removing oil and dirt from items without the need for additional cleaning fluid.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A cleaning machine is provided, comprising a water treatment module, a water storage module, a first micro-nano bubble generating module, and a cleaning module. The input end of the water treatment module can be connected to an external water source. The water treatment module is equipped with a magnetizer. The output end of the water treatment module is connected to the input end of the water storage module and the input end of the first micro-nano bubble generating module, respectively. The output end of the first micro-nano bubble generating module is connected to the water storage module. The output end of the water storage module is connected to the cleaning module. The water storage module is also equipped with a drain pipe.

[0007] With this setup, when cleaning is required, an external water source is connected to the water treatment module. The water is first magnetized by the magnetizer in the water treatment module, weakening the hydrogen bond network between water molecules and reducing the surface tension of the water. The water then enters the water storage module for storage. At the same time, the first micro-nano bubble generating module works, using the magnetized water in the water storage module to generate micro-nano bubbles. Because the surface tension of the water is reduced after magnetization, it is easier to generate small-sized bubbles, increasing the concentration of micro-nano bubbles in the water. Subsequently, the magnetized water containing micro-nano bubbles in the water storage module is sent to the cleaning module. The cleaning module sprays water containing micro-nano bubbles to clean items. The micro-nano bubbles contained in the water can improve the cleaning effect of the water: micro-nano bubbles can generate free radicals without external stimulation. When micro- and nano-bubbles contract, the charge density of the double layer increases rapidly. When the bubbles burst, the drastic change of the disappearance of the gas-liquid interface releases the energy stored in the high concentration of positive and negative ions on the interface. At this time, a large number of hydroxyl radicals can be generated, thereby increasing the activity of water and improving the cleaning effect of water. Moreover, when the bubbles burst, they generate jets that physically impact dirt on the surface of objects, turning oil stains and other dirt that are difficult to dissolve in water into small droplets, which are easy to emulsify with water. This achieves a high-quality cleaning effect without the need for external cleaning agents. After cleaning, the water is discharged through the drain pipe of the water storage module.

[0008] Preferably, the water treatment module further includes a weak alkalization tube, which is connected to the magnetizer. An external water source flows through the weak alkalization tube and the magnetizer before entering the water storage module and the first micro-nano bubble generating module.

[0009] With this setup, the weak alkali tube makes the water weakly alkaline. When water flows through the weak alkali tube and the magnetizer, the dipole moments of the two H1O bonds cannot cancel each other out, the centers of positive and negative charges do not coincide, and the entire molecule has high polarity. By utilizing the principle of attraction between the polarity of water molecules and the positive and negative charges of oil, water molecules can easily carry away the oil, thereby further improving the cleaning ability of the water.

[0010] Preferably, the magnetizer includes a magnetizing tube and a magnet. The magnet includes at least one magnet group arranged along the axial direction of the magnetizing tube. Each magnet group includes two magnets. The magnets are fixedly arranged on the outer surface of the magnetizing tube, and the opposite magnetic poles of the two magnets are opposite to each other. The magnetic field force parameter between the two magnets is 5000-6000 Gauss.

[0011] Preferably, the water storage module includes a first water tank, a first water pump, a second water pump, and a second water tank. The inlet of the first water tank is connected to the outlet of the water treatment module. The first water tank is connected to the cleaning module through the first water pump. The second water tank is installed below the cleaning module. The output of the first micro-nano bubble generating module is connected to the second water tank. The drain pipe is connected to the second water tank. The bottom of the second water tank is also provided with a return pipe. The return pipe is connected to the cleaning module through the second water pump. The drain pipe is connected to the outside.

[0012] In this setup, before cleaning, magnetized weakly alkaline water treated by the water treatment module enters the first water tank and the first micro-nano bubble generating module. The first water pump delivers water from the first water tank to the cleaning module for spraying, and the sprayed water naturally flows into the second water tank. At the same time, the first micro-nano bubble generating module generates a large number of micro-nano bubbles and sends them into the water in the second water tank. When the water level in the second water tank reaches a preset value, the pre-cleaning preparation is complete. The object to be cleaned is placed in the working area, and the second water pump operates, drawing water from the second water tank through the return pipe for the main wash of the object. The weakly alkaline magnetized water containing a large number of micro-nano bubbles can effectively remove oil stains from the surface of the object. The oily water flows back to the second water tank and is discharged through the drain pipe. Subsequently, the first water pump operates again, drawing weakly alkaline magnetized water from the first water tank to rinse the object. At this point, the water contains fewer contaminants and is stored in the second water tank for use in the next batch of objects to be cleaned. This helps to save water resources, reduce the wear rate of the filter media in the water treatment module, and improve environmental protection.

[0013] Preferably, the second water tank is equipped with a filter plate, which is installed at the water inlet of the second water tank.

[0014] With this configuration, the filter plate can filter the weakly alkaline magnetized water used for cleaning, preventing solids that easily sink to the bottom from entering the second water tank and being drawn up by the second water pump, thus avoiding clogging and damage to the second water pump, and improving the cleanliness of the recycled water.

[0015] Preferably, the second water tank has an open top. This design allows the cleaned water to fall freely into the second water tank, which helps improve recycling efficiency.

[0016] Preferably, the second water tank is provided with an overflow pipe, and the top of the overflow pipe has an overflow port, which is connected to the drain pipe.

[0017] With this setup, during the main wash, the solids washed down are blocked by the filter plate, and only the oil flows back into the second water tank with the water. The oil layer floats on the top of the second water tank, and the second water pump draws clean water from the return pipe of the second water tank to circulate and clean the items to be cleaned. After the main wash is completed and the rinsing step is started, the first water pump draws water from the first water tank to clean the items to be cleaned. After the cleaning is completed, the water flows into the second water tank, at which point the water level in the second water tank rises, and the oil layer on the top of the second water tank flows into the drain pipe from the overflow port at the top of the overflow pipe and is discharged.

[0018] Preferably, it includes a heating device for heating the water in the first water tank, the heating device being installed inside or outside the first water tank, and the first water tank being provided with an exhaust pipe for discharging steam, the exhaust pipe being connected to the outside.

[0019] With this configuration, the first water tank can heat the water, improving its ability to dissolve pollutants and enhancing the cleaning effect. When the water in the first water tank is heated, it will generate steam, causing the pressure inside the first water tank to increase. At this time, the steam can be discharged through the exhaust pipe to prevent the pressure inside the first water tank from becoming too high and causing an explosion.

[0020] Preferably, the heating device uses gas heating and is also equipped with a flue pipe.

[0021] With this setup, gas heating can reduce energy costs compared to electric heating, and the exhaust pipe is used to discharge the exhaust gas generated by combustion in the heating device.

[0022] Preferably, the second water tank is also equipped with an electric heating element. This arrangement allows the electric heating element to maintain the temperature of the water in the second water tank.

[0023] Preferably, the diameter of the bubbles in the water stream output from the output end of the first micro-nano bubble generating module is 50nm-1000nm.

[0024] Preferably, the system further includes an ozone generating module, the output of which is connected to the first micro / nano bubble generating module.

[0025] With this configuration, ozone can be dissolved into the water, thereby improving the water's sterilization ability and thus enhancing the cleaning effect. The first micro-nano bubble generating module produces a large number of micro-nano bubbles, which create a suspension-like effect in the water. Ozone can be stored within the micro-nano bubbles, further increasing the ozone content per unit volume of water and preventing ozone from escaping and forming an odor. This is beneficial for improving the working environment and enhancing the sterilization effect.

[0026] Preferably, the first micro-nano bubble generating module includes a bubble generator and a pressure-reducing water tank. The input end of the pressure-reducing water tank is connected to the output end of the water treatment module, the output end of the pressure-reducing water tank is connected to the input end of the bubble generator, the output end of the ozone generating module is connected to the input end of the bubble generator, and the output end of the bubble generator is connected to the second water tank.

[0027] This setup provides a buffer space for the pressure-reducing water tank, which lowers the water pressure output by the water treatment module. This facilitates the subsequent fusion of ozone and water in the bubble generator, preventing a decrease in ozone solubility in water due to excessive water pressure. This helps to increase the content of micro-nano bubbles and ozone in the water.

[0028] Preferably, the bubble generator includes a self-priming pump and a mixing chamber. The output end of the ozone generating module and the output end of the pressure-reducing water tank are respectively connected to the input end of the mixing chamber. The self-priming pump is used to generate negative pressure to make water flow from the pressure-reducing water tank to the mixing chamber. The output end of the mixing chamber is connected to the second water tank.

[0029] With this setup, the self-priming pump generates negative pressure to draw water from the depressurization tank into the mixing chamber. Ozone and water mix in the mixing chamber, and the water repeatedly shears and breaks down the ozone through high-speed swirling and hydraulic shearing. This causes some ozone to mix in the water, generating ozone micro-nano bubbles, while some ozone dissolves directly in the water, forming ozone-rich water that is then transported to the second tank. The second water pump then acts on the cleaning module, increasing the ozone content and enhancing the bactericidal effect of ozone, thereby improving the cleaning effect of the water.

[0030] Preferably, the cleaning machine further includes an electrical control cabinet, which is electrically connected to the first water pump, the second water pump, the first micro-nano bubble generating module, and the ozone generating module.

[0031] Preferably, the cleaning machine further includes a water collection tank, which is installed at the bottom of the cleaning module, and the top of the second water tank is open, with the top of the second water tank embedded in the bottom of the water collection tank.

[0032] The cleaning module includes an upper nozzle and a lower nozzle, with the lower nozzle mounted on the water collection tank, meaning the water collection tank is located at the bottom of the upper and lower nozzles. With this arrangement, when the upper and lower nozzles spray water for cleaning, the water falls after rinsing the surface of the object to be cleaned, is collected by the water collection tank, and flows into a second water tank embedded within the water collection tank, thus achieving water recycling.

[0033] A cleaning system includes a cleaning machine as described above, and further includes a pre-wash device, the pre-wash device comprising:

[0034] A pre-washing tank is used to hold items to be washed, and the top of the pre-washing tank is open.

[0035] A filter tank is installed inside the 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.

[0036] The second micro-nano bubble generating module is located next to the pre-wash tank. The input end of the second micro-nano bubble generating module is connected to the filter tank, and the output end of the second micro-nano bubble generating module is connected to the pre-wash tank.

[0037] 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.

[0038] The drain pipe is provided with a first recovery port, and the filter tank is provided with a second recovery port. The first recovery port and the second recovery port are connected.

[0039] The first recovery port is equipped with a solenoid valve or a manual opening / closing port. With this setup, during rinsing, the upper layer of water containing oil in the second water tank is first discharged through the overflow pipe and drain pipe. After the oily wastewater is drained, the user can open the first recovery port through the solenoid valve or manual opening / closing. The subsequently discharged oil-free, weakly alkaline magnetic water containing micro-nano bubbles can be transported to the filter tank through the first recovery port. The filter tank can also filter the water after pre-rinsing in the pre-rinse tank. The recovery system extracts the water after filtration and reuses it in the pre-rinse tank to pre-rinse the items to be cleaned, which helps to save water resources, reduce filter element wear, and improve cleaning effect. At the same time, the second micro-nano bubble generating module generates micro-nano bubbles in the pre-rinse tank, improving the pre-rinse effect of the items to be cleaned in the pre-rinse tank.

[0040] Compared with the prior art, the beneficial effects of this utility model are:

[0041] (1) By setting up the water treatment module and the first micro-nano bubble generating module, magnetized water with micro-nano bubbles is generated, which changes the physical and chemical properties of the water and improves the water's ability to remove dirt. High-quality cleaning effect can be achieved without the addition of external cleaning agents.

[0042] (2) By setting up a weak alkali pipe, the water body becomes weakly alkali water, which further improves the cleaning effect of the water body.

[0043] (3) By setting up a water storage module, the magnetized weakly alkaline water can be recycled, which can reduce water consumption and the consumption of consumables in the water treatment module, thus improving environmental protection.

[0044] (4) By setting up a heating device, the temperature of the water body is increased, the dissolving capacity of the water body is increased, and the cleaning effect is further improved.

[0045] (5) By using gas heating, energy costs are reduced compared to electric heating.

[0046] (6) By combining the ozone generating module with the first micro-nano bubble generating module, more ozone can be contained in the water body, and ozone overflow is effectively avoided. This can improve the sterilization ability of the water body and prevent ozone from polluting the outside air and producing odors.

[0047] (7) The cleaning system combining the cleaning machine and the pre-washing tank realizes the recycling of weakly alkaline magnetized water, reduces water waste and the consumption of consumables in the water treatment module, and improves environmental protection capabilities.

[0060] Example 1

[0061] like Figures 1 to 5 The first embodiment of the cleaning machine of this utility model is shown, including a water treatment module 1, a water storage module 2, a first micro-nano bubble generating module 3, and a cleaning module 4. The input end of the water treatment module 1 can be connected to an external water source. The water treatment module 1 is equipped with a magnetizer 11. The output end of the water treatment module 1 is connected to the input end of the water storage module 2 and the input end of the first micro-nano bubble generating module 3, respectively. The output end of the first micro-nano bubble generating module 3 is connected to the water storage module 2. The output end of the water storage module 2 is connected to the cleaning module 4. The water storage module 2 is also equipped with a drain pipe 241.

[0062] With this setup, when cleaning is required, an external water source is connected to the water treatment module 1. The water source is first magnetized by the magnetizer 11 in the water treatment module 1, which weakens the hydrogen bond network between water molecules and reduces the surface tension of the water. Then, the water enters the water storage module 2 for storage. At the same time, the first micro-nano bubble generating module 3 works, using the magnetized water in the water storage module 2 to generate micro-nano bubbles. Since the surface tension of the water is reduced after magnetization, it is easier to generate small-sized bubbles, increasing the concentration of micro-nano bubbles in the water. Then, the magnetized water containing micro-nano bubbles in the water storage module 2 is sent to the cleaning module 4. The cleaning module 4 sprays water containing micro-nano bubbles to clean the items. The micro-nano bubbles contained in the water can improve the cleaning effect of the water: micro-nano bubbles can generate free radicals without external stimulation. When micro- and nano-bubbles contract, the charge density of the double layer increases rapidly. When the bubbles burst, the drastic change of the disappearance of the gas-liquid interface releases the energy stored in the high concentration of positive and negative ions on the interface. At this time, a large number of hydroxyl radicals can be generated, thereby increasing the activity of water and improving the cleaning effect of water. Moreover, when the bubbles burst, they generate jets that physically impact dirt on the surface of objects, turning oil stains and other dirt that are difficult to dissolve in water into small droplets, which are easy to emulsify with water. This achieves a high-quality cleaning effect without the need for external cleaning agents. After cleaning, the water is discharged through the drain pipe 241 of the water storage module 2.

[0063] As one embodiment of this utility model, the water treatment module 1 also includes a weak alkalization tube 12, which is connected to the magnetizer 11. After the external water source flows through the weak alkalization tube 12 and the magnetizer 11, it enters the water storage module 2 and the first micro-nano bubble generating module 3.

[0064] With this setup, the weak alkali tube 12 makes the water weakly alkaline. When the water flows through the weak alkali tube 12 and the magnetizer 11, the dipole moments of the two H1O bonds cannot cancel each other out, the centers of positive and negative charges do not coincide, and the whole molecule has high polarity. By utilizing the principle of attraction between the polarity of water molecules and the positive and negative charges of oil, water molecules can easily carry away the oil, thereby further improving the cleaning ability of the water.

[0065] As one embodiment of this utility model, the water storage module 2 includes a first water tank 21, a first water pump 22, a second water pump 23, and a second water tank 24. The inlet end of the first water tank 21 is connected to the outlet end of the water treatment module 1. The first water tank 21 is connected to the cleaning module 4 through the first water pump 22. The second water tank 24 is installed below the cleaning module 4. The output end of the first micro-nano bubble generating module 3 is connected to the second water tank 24. The drain pipe 241 is connected to the second water tank 24. The bottom of the second water tank 24 is also provided with a return pipe 242. The return pipe 242 is connected to the cleaning module 4 through the second water pump 23. The drain pipe 241 is connected to the outside.

[0066] In this setup, before cleaning, magnetized weakly alkaline water treated by water treatment module 1 enters the first water tank 21 and the first micro-nano bubble generating module 3, respectively. The first water pump 22 delivers the water from the first water tank 21 to the cleaning module 4 for spraying. The sprayed water naturally flows into the second water tank 24. At the same time, the first micro-nano bubble generating module 3 generates a large number of micro-nano bubbles and sends them into the water in the second water tank 24. When the water level in the second water tank 24 reaches a preset value, the pre-cleaning preparation is complete. The object to be cleaned is then placed in the working area, and the second water pump 23 operates, flowing through the return pipe... 242. Water from the second water tank 24 is drawn to perform a primary wash on the items to be cleaned: the weakly alkaline magnetized water containing a large number of micro-nano bubbles can effectively remove oil stains from the surface of the items to be cleaned. The oily water is returned to the second water tank 24 and discharged through the drain pipe 241. Then, the first water pump 22 works to draw weakly alkaline magnetized water from the first water tank 21 to rinse the items to be cleaned. At this time, the water contains fewer pollutants and is stored in the second water tank 24 for use in the next batch of items to be cleaned. This helps to save water resources, reduce the wear rate of the filter media in the water treatment module 1, and improve environmental protection.

[0067] As one embodiment of this utility model, a filter plate is provided inside the second water tank 24, and the filter plate is installed at the water inlet of the second water tank 24.

[0068] With this setup, the filter plate can filter the weakly alkaline magnetized water used for cleaning, preventing solids that easily sink to the bottom from entering the second water tank 24 and being drawn up by the second water pump 23, thus avoiding clogging and damage to the second water pump 23, and improving the cleanliness of the recycled water.

[0069] In one embodiment of this invention, the top of the second water tank 24 is open. This design allows the cleaned water to fall freely into the second water tank 24, which improves recycling efficiency.

[0070] As one embodiment of this utility model, the second water tank 24 is provided with an overflow pipe, and an overflow port is opened at the top of the overflow pipe, which is connected to the drain pipe 241.

[0071] With this setup, during the main wash, the solids washed down are blocked by the filter plate, and only the oil flows back into the second water tank 24 with the water. The oil layer floats on the upper layer of the second water tank 24. The second water pump 23 draws clean water from the return pipe 242 of the second water tank 24 to circulate and clean the items to be cleaned. After the main wash is completed and the rinsing step is started, the first water pump 22 draws water from the first water tank 21 to clean the items to be cleaned. After the cleaning is completed, the water flows into the second water tank 24, at which time the water level in the second water tank 24 rises, and the oil layer on the upper layer of the second water tank 24 flows into the drain pipe 241 from the overflow port at the top of the overflow pipe and is discharged.

[0072] As one embodiment of this utility model, the first water tank 21 is also provided with a heating device, and the first water tank 21 is provided with an exhaust pipe 211 for discharging steam, and the exhaust pipe 211 is connected to the outside.

[0073] With this configuration, the first water tank 21 can heat the water, thereby improving the water's ability to dissolve pollutants and enhancing the cleaning effect. When the water in the first water tank 21 is heated, it will generate steam, which will increase the pressure inside the first water tank 21. At this time, the steam can be discharged through the exhaust pipe 211 to prevent the first water tank 21 from becoming too pressurized and exploding.

[0074] As one embodiment of this utility model, the heating device adopts gas heating and is also equipped with a flue pipe.

[0075] With this setup, gas heating can reduce energy costs compared to electric heating, and the exhaust pipe is used to discharge the exhaust gas produced by combustion in the heating device.

[0076] As one embodiment of this utility model, an electric heating element is also provided inside the second water tank 24. This arrangement allows the electric heating element to maintain the temperature of the water inside the second water tank 24.

[0077] To facilitate the description of the internal pipe relationships, a cleaning input pipe 41 is introduced here, which is connected to the input end of the cleaning module 4.

[0078] Example 2

[0079] like Figures 1 to 6 The following is a second embodiment of a cleaning machine according to the present invention. This embodiment is similar to the previous one, except that it also includes an ozone generating module 5.

[0080] As one embodiment of this utility model, it also includes an ozone generating module 5, the output end of which is connected to the first micro-nano bubble generating module 3.

[0081] With this setup, ozone can be incorporated into the water, thereby enhancing the water's sterilization ability and improving the cleaning effect. The first micro-nano bubble generating module 3 generates a large number of micro-nano bubbles, which produce a suspension-like effect in the water. Ozone can be stored in the micro-nano bubbles, further increasing the ozone content per unit of water and preventing ozone from overflowing and forming an odor. This is beneficial for improving the working environment and enhancing the sterilization effect.

[0082] As one embodiment of this utility model, the first micro-nano bubble generating module 3 includes a bubble generator 32 and a pressure-reducing water tank 31. The input end of the pressure-reducing water tank 31 is connected to the output end of the water treatment module, the output end of the pressure-reducing water tank 31 is connected to the input end of the bubble generator 32, the output end of the ozone generating module 5 is connected to the input end of the bubble generator 32, and the output end of the bubble generator 32 is connected to the second water tank 24.

[0083] With this configuration, the pressure-reducing water tank 31 provides a buffer space, which reduces the water pressure output by the water treatment module. This facilitates the subsequent fusion of ozone and water in the bubble generator 32, preventing the ozone solubility in water from decreasing due to excessive water pressure. This is beneficial for increasing the content of micro-nano bubbles and ozone in the water.

[0084] As one embodiment of the present invention, the bubble generator 32 includes a self-priming pump 321 and a mixing chamber 322. The output end of the ozone generating module 5 and the output end of the pressure-reducing water tank 31 are respectively connected to the input end of the mixing chamber 322. The self-priming pump 321 is used to generate negative pressure to make water flow from the pressure-reducing water tank 31 to the mixing chamber 322. The output end of the mixing chamber 322 is connected to the second water tank 24.

[0085] With this setup, the self-priming pump 321 generates negative pressure to draw water from the depressurization tank 31 into the mixing chamber 322. Ozone and water mix in the mixing chamber 322. The water in the mixing chamber 322 repeatedly shears and breaks down the ozone through high-speed swirling and hydraulic shearing, causing some ozone to mix in the water and generate ozone micro-nano bubbles. Some ozone is also dissolved directly in the water, thus forming an ozone-rich water body, which is then transported to the second water tank 24. The second water pump 23 then acts on the cleaning module 4, increasing the ozone content and improving the bactericidal effect of ozone, thereby improving the cleaning effect of the water body.
