[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] In order to improve the cleaning power of water for clothes, this application provides a water treatment device and a washing machine, which will be described below with reference to the accompanying drawings.

[0028] For example, please refer to Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the water treatment device provided in an embodiment of this application. Figure 2 This is another structural schematic diagram of the water treatment device provided in the embodiments of this application. The water treatment device 100 includes a mounting box 110, a microbubble generator 120, and a magnetization component 130.

[0029] Mounting box 110 is used to mount or fix microbubble generator 120 and magnetization component 130. Mounting box 110 has a first mounting space 112, a second mounting space 114 and a third mounting space 116. The second mounting space 114 is located between the first mounting space 112 and the third mounting space 116, or in other words, the second mounting space 114 is sandwiched between the first mounting space 112 and the third mounting space 116. It should be noted that the above is for the purpose of illustrating the relative positional relationship of the first mounting space 112, the second mounting space 114 and the third mounting space 116, and should not be construed as a limitation on the first mounting space 112, the second mounting space 114 and the third mounting space 116.

[0030] A microbubble generator 120 is installed within the second installation space 114. The microbubble generator 120 is connected to a water source and can treat the water to generate microbubbles. Microbubbles have a large specific surface area, slow rising speed, negative charge effect, implosion release of energy, and generation of hydroxyl radicals, resulting in highly efficient cleaning capabilities for stains. The negatively charged surface of microbubbles attracts positively charged dirt (such as proteins and dyes), causing it to detach from the fibers. It is suitable for removing charged stains such as blood stains, tea stains, and ink stains. When microbubbles burst, they generate localized high voltage (>1000 atm) and microjets, impacting and stripping dirt. Microbubbles undergo Brownian motion in water, allowing them to penetrate deeper into fiber gaps and remove deep-seated stains. When microbubbles burst, they briefly generate hydroxyl radicals (·OH), which can oxidize and decompose organic stains (such as oil stains and sweat stains). Microbubbles can increase dissolved oxygen in water, enhance the enzyme activity of detergents (such as proteases and lipases), and improve cleaning efficiency. This can be achieved through high-speed shearing methods such as mechanical stirring or the Venturi effect. The principle is to generate turbulence by high-speed water flow or gas jet, which shears gases such as air or ozone to form microbubbles.

[0031] The magnetization component 130 is disposed within the first installation space 112 and the third installation space 116, forming a magnetized space. The microbubble generator 120 is located within the magnetized space. The magnetization component 130 can generate magnetic lines of force and magnetize the water flow within the microbubble generator 120. After the water is magnetized by a strong magnetic field, the trajectory of charged ions (such as calcium and magnesium ions) in the water is deflected under the action of the Lorentz force, reducing scale deposition. After magnetization, water molecule clusters may become smaller, increasing permeability. Experiments show that surface tension can be reduced by 5%-10%, which helps detergent foaming and stain removal. Some studies indicate that the pH rises slightly (0.5-1 unit) after magnetization, and the increased pH value is beneficial for washing. Magnetization changes water quality, which can reduce detergent usage and inhibit scale deposition. Due to the increased permeability, detergent efficiency may be improved, which can be achieved by using low-temperature water, as high temperatures weaken the magnetization effect. Inhibiting scale deposition can extend the life of the washing machine heating element and reduce the hardening of clothing fibers.

[0032] In the water treatment device 100 of this application embodiment, a microbubble generator 120 is used to generate microbubbles. Microbubbles have characteristics such as large specific surface area, negative charge effect, and the ability to generate hydroxyl radicals through implosion energy release, which have a highly efficient cleaning ability for stains, that is, improving cleaning power by changing the water flow pattern. A magnetization component 130 is used to magnetize the water. Under the action of Lorentz force, the trajectory of charged ions in the water is deflected, which can reduce scale deposition, that is, improving cleaning ability by changing the water quality. This application embodiment uses the microbubble generator 120 and the magnetization component 130 in combination to change the water quality and water flow pattern, promoting the improvement of cleaning ability from different angles.

[0033] For example, please continue reading Figure 2 The magnetization component 130 includes a first permanent magnet 132 and a second permanent magnet 134. The polarity of the first permanent magnet 132 is opposite to that of the second permanent magnet 134. One of the first permanent magnet 132 and the second permanent magnet 134 is disposed in the first mounting space 112, and the other is disposed in the third mounting space 116.

[0034] The magnetic flux of the first permanent magnet 132 and the second permanent magnet 134 should not be less than 50,000 gs. The material of the first permanent magnet 132 and the second permanent magnet 134 can be neodymium iron boron, and the number of the first permanent magnet 132 and the second permanent magnet 134 is the same. For example, the first permanent magnet 132 and the second permanent magnet 134 with a single larger area can be set opposite each other and set on both sides of the microbubble generator 120. For example, the first permanent magnet 132 and the second permanent magnet 134 can be symmetrically arranged along the microbubble generator 120.

[0035] The first mounting space 112 and the third mounting space 116 can be slots to accommodate the first permanent magnet 132 and the second permanent magnet 134. The first permanent magnet 132 and the second permanent magnet 134 can be fixed by snap-fit. For ease of explanation, this embodiment uses the example of the first permanent magnet 132 being installed in the first mounting space 112 and the second permanent magnet 134 being installed in the third mounting space 116 as an example, and should not be construed as a limitation on the installation positions of the first permanent magnet 132 and the second permanent magnet 134.

[0036] For example, the water treatment device 100 may include a first latching group 142 and a second latching group 144.

[0037] The first latch group 142 includes at least two latches, which are disposed opposite to each other in the first installation space 112, that is, at least two latches are disposed opposite to each other on the groove wall and protrude from the groove wall, so as to clamp the first permanent magnet 132 from both sides and fix the first permanent magnet 132.

[0038] Similarly, the second snap-fit ​​assembly 144 can be configured similarly to the first snap-fit ​​assembly 142 to facilitate manufacturing and simplify positioning. The second snap-fit ​​assembly 144 includes at least two snaps, which are disposed opposite to each other in the third mounting space, that is, at least two snaps are disposed opposite to each other on the groove wall and protrude from the groove wall, so as to clamp the second permanent magnet 134 from both sides and fix the second permanent magnet 134.

[0039] The mounting box 110 can be provided with heat dissipation holes at the locations of the first permanent magnet 132 and the second permanent magnet 134 to dissipate the heat generated in the system and to allow users to easily view the status of the first permanent magnet 132 and the second permanent magnet 134 from the front of the mounting box 110 without disassembly.

[0040] It should be noted that the buckle setting can be based on the installation and disassembly directions of the first permanent magnet 132 and the second permanent magnet 134, and no specific restrictions are imposed here.

[0041] For example, please refer to Figure 1 and Figure 2 And see Figure 3 and Figure 4 As shown, Figure 3 This is another structural schematic diagram of the water treatment device provided in the embodiments of this application. Figure 4 for Figure 3The diagram shows a cross-sectional view of the water treatment device along line AA. The microbubble generator 120 includes a venturi tube 122, which comprises a converging section 1220, a throat section 1222, and a diffuser section 1224 connected in sequence. The venturi tube 122 also includes an air inlet section 1226 connected to the throat section 1222. The converging section 1220 has a water inlet, the diffuser section 1224 has a water outlet, and the end of the air inlet section 1226 furthest from the throat section 1222 is an air inlet. Air and water mix within the venturi tube 122 downstream of the air inlet section 1226 to form microbubbles.

[0042] The contraction section 1220, the throat section 1222, and the diffusion section 1224 are arranged in a direction perpendicular to the magnetic field lines of the magnetization assembly 130.

[0043] The Venturi tube 122 can be secured using arc-shaped clips. For example, the water treatment device 100 further includes a third clip group 146, which comprises at least two arc-shaped clips arranged along the extension directions of the constriction section 1220, the throat section 1222, and the diffuser section 1224 to secure the Venturi tube 122. It is understood that one arc-shaped clip can be used to secure the constriction section 1220, and the other arc-shaped clip can be used to secure the diffuser section 1224, thereby securing at least the constriction section 1220 and the diffuser section 1224 to secure the Venturi tube 122.

[0044] Please see Figures 5 to 8 As shown, Figure 5 This is another structural schematic diagram of the water treatment device provided in the embodiments of this application. Figure 6 This is another structural schematic diagram of the water treatment device provided in the embodiments of this application. Figure 7 for Figure 6 The diagram shows a cross-sectional view of the water treatment device along BB. Figure 8 for Figure 5 The diagram shows an exploded view of the water treatment device. To further enhance the cleaning ability of clothing, the water treatment device 100 of this embodiment also integrates an ion generator 150. The ion generator 150 is installed on the side of the mounting box 110 away from the second mounting space 114 and is connected to the air inlet of the microbubble generator 120. The ion generator 150 is used to generate antibacterial molecules and is directed to the microbubble generator 120.

[0045] For example, the water treatment device 100 also includes an installation pipe 160, which is connected to the installation box 110, and the air vent of the installation pipe 160 is connected to the air inlet of the microbubble generator 120. The ion generator 150 is installed on the installation pipe 160.

[0046] It should be noted that the ion generator 150 can be a negative ion generator, cloud ion generator, plasma generator, or other functional modules that can ionize air to generate sterilizing and cleaning components.

[0047] A negative ion generator is a device that generates negative air ions. It utilizes a high-voltage DC source to produce a high corona discharge, rapidly releasing a large number of electrons (e-). Since electrons cannot exist in the air for long (their lifetime is only on the order of nanoseconds), they are immediately captured by oxygen molecules (O2) in the air, thus generating negative air ions. These ions have bactericidal, preservative, and odor-removing effects. Antibacterial molecules such as negative ions enhance cleaning power, inhibit bacteria and odors, and reduce static electricity during laundry. Negative ions neutralize the positive charge on the surface of stain particles such as dust and oil, reducing electrostatic adsorption between dirt and fibers, making stains easier to remove from clothing. Negative ions can destroy bacterial cell membranes, inhibiting microbial reproduction, and decompose odor molecules such as sweat and mildew, making them suitable for underwear, sportswear, etc. After washing, the clothing fibers carry negative ions, reducing static electricity buildup during drying and making the fabric softer.

[0048] The cloud ion generator is a device that generates negative air ions and ozone. After air is ionized, it produces a large number of negative ions and ozone, which have bactericidal and deodorizing effects. Antibacterial molecules such as ozone have the function of oxidizing and decomposing organic matter, sterilizing and deodorizing during clothing washing. Ozone is a strong oxidant that can effectively decompose organic stains such as grease, sweat stains, and proteins, as well as blood stains and food residues, especially stubborn stains that are difficult to remove with traditional detergents. The oxidizing effect of ozone can partially replace chemical detergents, reducing dependence on cleaning agents, making it suitable for environmentally conscious individuals or those with sensitive skin. Ozone can kill bacteria and mold on clothing and decompose odor molecules such as smoke and sweat odor, making it suitable for scenarios with high disinfection requirements, such as underwear and sportswear.

[0049] The main working principle of the plasma generator is to raise the low voltage to positive and negative high voltage through the boost circuit. The positive and negative high voltage of the discharge needle generates corona discharge on the grounded metal ring, ionizing the air and generating a large number of positive and negative air ion groups, thereby sterilizing, removing odors, eliminating smoke, and improving air quality.

[0050] This application uses an ion generator 150, which can generate negative ions and ozone, as an example for illustration.

[0051] For example, the assembly sequence of the water treatment device 100 is as follows: The ion generator 150 is fastened to the mounting box 110 using limiting ribs and screws (not shown). At this time, the discharge needle of the ion generator 150 is sealed into the ionization chamber of the mounting box 110 through a circular hole. A sealing ring is fitted onto the portion of the mounting box 110 above the step. Then, the venturi tube 122 is assembled together with the arc-shaped buckle and its support portion on the mounting box 110, axially limited by the limiting ribs on the venturi tube 122. Simultaneously, the cylindrical portion of the air inlet section 1226 of the venturi tube 122 above the funnel is fitted onto the cylinder of the mounting box 110, and sealed by the sealing ring. This forms a relatively sealed ionization chamber. The first permanent magnet 132 and the second permanent magnet 134 are respectively installed into the mounting slots, namely the first mounting space 112 and the third mounting space 116. Note that the permanent magnets are installed symmetrically, with the N pole and the S pole corresponding. The magnetic lines of force formed between them are as perpendicular as possible to the Venturi tube 122. The permanent magnets are positioned and fixed by buckles and limiting ribs, which is convenient and quick.

[0052] For example, the working process of the water treatment device 100 is as follows: while water flows through the venturi tube 122, the vertical magnetic lines of force formed by the permanent magnet magnetize the water flow, thus softening the water quality after magnetization. At the same time, the ion generator 150 is powered on, and the air, due to the negative pressure at the air inlet section 1226 of the venturi tube 122, is ionized by the ion generator 150 to form a gas containing negative ions and ozone. The water in the venturi tube 122 mixes with this gas to form microbubbles containing negative ions and ozone. The beneficial effect of negative ions and ozone on washing is utilized to enhance the washing capacity of the washing machine.

An embodiment of this application also provides a washing machine 1000, which includes the water treatment device 100 as described above.

Since this washing machine 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0054] The washing machine 1000 also includes a water inlet pipe 200 and a circulation pipe 300. A water treatment device 100 is installed at the water inlet pipe 200, and / or at the circulation pipe 300. One option is to install an ion generator magnetized microbubble composite module, i.e., the water treatment device 100, on the water inlet pipe 200. One end is connected to the water inlet valve, and the other end is directly connected to the washing machine tub. The treated water enters the tub directly. Alternatively, the water inlet pipe can be equipped with a water filter box. After passing through the water filter box, the water treated by the water treatment device 100 rinses the detergent before entering the tub. A third installation option involves connecting a circulation pump to the circulation pipe 300 at one end and the tub at the other. This option allows for continuous circulation of the washing water, ensuring a sufficient content of microbubbles.
