[0062] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application but should not be used to limit the scope of the present application.

[0063] In the specific embodiments, each specific technical feature and each embodiment described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different specific technical features / embodiments can be combined to form different embodiments. In order to avoid unnecessary repetition, each possible combination of the specific technical features / embodiments in the present application will not be described again. In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The present application will be further described in conjunction with the drawings and specific embodiments.

[0064] In the related art, the cathode and the anode of the electrolysis device are arranged apart, that is, a spacing must be reserved between the cathode and the anode. In the process of electrolyzing the water solution by the cathode and the anode, ion conduction in the water solution is relied on, and water quality in different regions differs greatly, for example, water quality TDS in Wuxi is about 150, while that in Xinjiang and other northern regions is as high as 500; TDS in Japan is about 80, while that in Europe and North America is as high as more than 500. TDS (Total Dissolved Solids) refers to the concentration of total dissolved solids in water, mainly reflecting the concentration of calcium, magnesium and other ions in water, and has a good corresponding relationship with water hardness and conductivity. For example, the smaller the TDS value, the lower the concentration of calcium, magnesium and other ions in water, and the smaller the conductivity. The difference in water quality can lead to two extreme cases. The first case is that the TDS of the water solution is too low, close to pure water, and the ion in the water solution is too low to conduct electricity, thereby causing the electrolytic water device to be unable to electrolyze. The second case is that the TDS is too high, and the water quality is too hard, causing the power of the anode and the cathode to rise sharply, resulting in short-circuit protection, and the anode and the cathode quickly decay due to scale. Therefore, the difference in TDS of water quality leads to unstable electrolytic water effect.

[0065] The first aspect of the embodiments of the present application provides an electrolysis device 100, which can be used in a clothes treatment apparatus 1000.

[0066] Referring to FIGS. 1 to 9, the electrolysis device 100 includes an electrode assembly 10, the electrode assembly 10 including a solid-state electrolyte 121, a support framework 122, and electrode sheets 11, the solid-state electrolyte 121 being disposed on the support framework 122; at least one of the electrode sheets 11 being a cathode 111, and at least one of the electrode sheets 11 being an anode 112, the cathode 111 and the anode 112 being stacked along a first direction, and the solid-state electrolyte 121 being disposed between the cathode 111 and the anode 112.

[0067] The solid-state electrolyte 121 is in a solid state and has an ion transmission function. The cathode 111 and the anode 112 can both be made of materials known in the art that can be used for electrolysis.

[0068] The solid-state electrolyte 121 is used for migration of at least one of anions and cations. The support framework 122 is used to enhance the mechanical strength of the solid-state electrolyte 121, so that the solid-state electrolyte 121 is not easily punctured, which is conducive to reducing the risk of internal short circuit. In addition, the solid-state electrolyte 121 is also not easily damaged during assembly of the electrolysis device 100.

[0069] The type of the solid-state electrolyte 121 is not limited, and the solid-state electrolyte 121 can be a proton membrane for migration of hydrogen ions, or can be another type of solid-state membrane, for example, the solid-state electrolyte 121 can be a solid polymer solid-state electrolyte (SPEM).

[0070] The electrode assembly 10 is used for electrolyzing fluid. The fluid can be water. The present application takes the fluid as water as an example for illustration. The electrode assembly 10 can be used for electrolyzing water to generate hydroxyl radicals and / or ozone and the like having strong oxidizing activity.

[0071] The principle of the electrode assembly 10 electrolyzing water is that a solid-state electrolyte 121 is arranged between the cathode 111 and the anode 112, the solid-state electrolyte 121 separates the cathode 111 and the anode 112, and the solid-state electrolyte 121 can transmit ions. In the process of the electrode assembly 10 electrolyzing water, water molecules are ionized to generate cations and anions, at least one of the cations and the anions can migrate through the solid-state electrolyte 121, for example, hydrogen ions can migrate through the solid-state electrolyte 121, and the solid-state electrolyte 121 forms high-concentration cation regions and anion regions on both sides of the solid-state electrolyte 121 along the first direction. The surface of the anode 112 generates hydroxyl radicals and / or ozone and the like having strong oxidizing activity, and the surface of the cathode 111 generates hydrogen.

[0072] Ozone can have a sterilization or bacteriostasis effect on clothes and the like, and ozone can also oxidize and destroy the color-developing groups of dye molecules that are free in water to decolor the dye, prevent free dye from staining light-colored clothes to cause color bleeding, continue to react to decompose the dye molecules into harmless carbon dioxide, water and / or inorganic salt, without secondary pollution, and play a role in preventing color bleeding.

[0073] Hydroxyl radicals (·OH) have extremely high oxidation potential (2.80 eV), and have extremely strong oxidizing ability, can have a sterilization or bacteriostasis effect on clothes and the like, and can have a rapid chain reaction with most organic pollutants, non-selectively oxidizing harmful substances into carbon dioxide, water or inorganic salt, without secondary pollution, and hydroxyl radicals can also oxidize and destroy free dye to decolor the dye, playing a role in preventing color bleeding.

[0074] The cathode 111 produces hydrogen gas microbubbles, and since the diameter of the microbubbles is very small, usually no more than 50 μm (microns), the hydrogen gas microbubbles can enter the inside of clothes fibers well during washing, and through the effects of microbubble burst, adsorption and floating, the microbubbles circulate to wash clothes, assisting detergents to remove sebum, oil, small dust and other dirt accumulated in the inside of clothes fibers, and can improve the cleaning ratio.

[0075] It should be noted that the stacking of the cathode 111 and the anode 112 in the first direction means that the anode 112 and the cathode 111 are arranged in a substantially face-to-face manner. For example, referring to FIGS. 1 and 2, the cathode 111, the anode 112, and the solid-state electrolyte 121 are substantially in the form of a flat plate, and the anode 112, the solid-state electrolyte 121, and the cathode 111 are sequentially stacked in the first direction, that is, the anode 112, the solid-state electrolyte 121, and the cathode 111 are arranged in a substantially face-to-face parallel manner. In this way, the distance between the two electrodes can be reduced as much as possible, the energy consumption can be reduced, and the electrolysis efficiency of the electrolysis device 100 can be improved without the anode 112 and the cathode 111 being in contact and short-circuiting.

[0076] The electrolysis device 100 provided by the embodiments of the present application has the following advantages. On the one hand, the solid-state electrolyte 121 is arranged between the anode 112 and the cathode 111, which can prevent the anode 112 and the cathode 111 from being in contact and short-circuiting. The solid-state electrolyte 121 can transmit ions and can not rely on ion conduction in water, thereby avoiding the influence of water quality on the power of the electrode sheet 11. On the other hand, the solid-state electrolyte 121 is used for migration of at least one of anions and cations, and the support skeleton 122 is used for enhancing the mechanical strength of the solid-state electrolyte 121. The solid-state electrolyte 121 is not easily punctured, and the solid-state electrolyte 121 is not easily damaged during assembly of the electrolysis device 100.

[0077] Referring to FIG. 10, the second aspect of the embodiments of the present application provides a clothes treatment apparatus 1000, which includes a clothes treatment cavity and the electrolysis device 100 according to any one of the embodiments of the present application. The fluid after electrolysis of the electrode assembly 10 enters the clothes treatment cavity.

[0078] The clothes treatment cavity can be used for containing clothes.

[0079] The clothes treatment apparatus 1000 provided by the embodiments of the present application has the following advantages. After electrolysis of the water by the electrolysis device 100, hydroxyl radicals and / or ozone and other substances are generated. The water after electrolysis enters the clothes treatment cavity, and the hydroxyl radicals and / or ozone and other substances with strong oxidation activity play a role in sterilization and disinfection of clothes and prevention of color transfer. Hydrogen micro-bubbles can assist detergents in removing dirt such as sebum, oil, and small dust accumulated inside the fibers of clothes, and can improve the cleaning ratio.

[0080] For example, the clothes treatment apparatus 1000 has a first liquid path 200 in communication with the clothes treatment cavity. The first liquid path 200 can be in communication with a water source to supply water to the clothes treatment cavity. In this way, the clothes treatment apparatus 1000 has a clothes washing function. The electrolysis device 100 is arranged on the first liquid path 200 to electrolyze the water flowing into the clothes treatment cavity.

[0081] The water source can be a tap water source or a circulating water of the laundry treating apparatus 1000. That is, the water liquid can be tap water, which does not contain lint and hair and other impurities, so that the lint and other impurities can be prevented from adhering to the electrode assembly 10, thereby improving the service life of the electrolysis device 100.

[0082] The laundry treating apparatus 1000 can have functions other than the washing function. For example, the laundry treating apparatus 1000 can have a drying function. The drying function can be used to dry laundry.

[0083] The laundry treating apparatus 1000 can be a washing machine or a washer-dryer. The washer-dryer is a laundry treating apparatus 1000 that integrates a washing function and a drying function.

[0084] The laundry treating apparatus 1000 can include a drum assembly, and an axis of the drum assembly can extend in a horizontal direction. The laundry treating apparatus 1000 in this embodiment is also referred to as a drum-type laundry treating apparatus 1000. The axis of the drum assembly can extend in a vertical direction, and the laundry treating apparatus 1000 in this embodiment is also referred to as a pulsator-type laundry treating apparatus 1000.

[0085] In some embodiments, the drum assembly includes a rotatable inner drum. The inner drum has a loading / unloading opening, and the loading / unloading opening can face forward. The inner drum can be used to place and treat laundry. A user places or takes out laundry into or from the inner drum through the loading / unloading opening from the front. The inner drum can rotate, for example, laundry, water liquid, and detergent and other substances rotate with the inner drum, so that the laundry continuously changes its posture in the inner drum, and the water liquid and the detergent and other fluids change their flow directions with the inner drum.

[0086] In some embodiments, the inner drum can be substantially hollow and cylindrical.

[0087] In some embodiments, the drum assembly includes an outer tub, and the inner drum can be disposed in the outer tub. The outer tub can be used to hold water, and the inner drum can be used to hold laundry. In this embodiment, the inner drum is also referred to as a perforated inner drum because the outer tub holds water. Fluids can flow between the space between the outer tub and the inner drum and the space in the inner drum through the overflow hole of the inner drum.

[0088] In some embodiments, the outer tub can be substantially hollow and cylindrical.

[0089] In some embodiments, the inner drum holds water by itself and is also referred to as a non-perforated inner drum. The outer tub can or can not be disposed outside the non-perforated inner drum.

[0090] It can be understood that, in some embodiments, the drum assembly can only have the inner drum and does not have the outer tub described above. In this embodiment, the inner drum is a non-perforated inner drum, and the inner drum itself can hold water. The inner drum can be a single-drum structure. That is, the laundry treating apparatus 1000 only has the inner drum as a drum.

[0091] In some embodiments, the laundry treating apparatus 1000 includes a cabinet, and the drum assembly is disposed in the cabinet. The cabinet is provided with an opening in communication with the interior of the drum assembly. For example, the front door 400 of the cabinet has the opening.

[0092] In some embodiments, the cabinet can have a substantially hexahedral shape, such as a square or cuboid shape.

[0093] In some embodiments, referring to FIG. 10, the laundry treating apparatus 1000 includes a door body for selectively opening or closing the opening of the cabinet and a door gasket 500 for sealing the gap between the drum assembly and the opening of the front door 400. The door gasket 500 can be disposed around the axis of the drum assembly, which extends in the horizontal direction.

[0094] It should be noted that the axis of the door gasket 500 extends in the same direction as the axis of the drum assembly, and the axis of the door gasket 500 can extend in the horizontal direction.

[0095] In some embodiments, referring to FIG. 6, the solid-state electrolyte 121 covers at least one side of the support skeleton 122 in the first direction.

[0096] For example, in some embodiments, the solid-state electrolyte 121 covers one side of the support skeleton 122 in the first direction. In other embodiments, the solid-state electrolyte 121 covers two sides of the support skeleton 122 in the first direction. In other embodiments, the solid-state electrolyte 121 covers all the outer surfaces of the support skeleton 122.

[0097] In this embodiment, the solid-state electrolyte 121 is used for the migration of at least one of anions and cations. The support skeleton 122 is used to enhance the mechanical strength of the solid-state electrolyte 121, so that the solid-state electrolyte 121 is not easily punctured, which is conducive to reducing the risk of internal short circuit. In addition, the solid-state electrolyte 121 is also not easily damaged during the assembly of the electrolytic device 100.

[0098] It should be understood that the solid-state electrolyte 121 can have one layer or multiple layers, and the multiple layers include two layers and more than two layers, such as two layers or three layers, and the like.

[0099] In some embodiments, the solid-state electrolyte 121 can have an integrated structure with the support skeleton 122, that is, the solid-state electrolyte 121 can be adhered to the support skeleton 122 by its own force.

[0100] In some embodiments, the solid-state electrolyte 121 can be connected to the support framework 122 by fasteners 22. The solid-state electrolyte 121 can be attached to the support framework 122 in any manner, such as by coating, deposition, or the like.

[0101] In some embodiments, referring to FIG. 3, the support framework 122 has a mesh structure. The support framework 122 having a mesh structure is easy to process and shape, and is beneficial to the stability of its own structure, thereby enhancing the structural stability of the electrode assembly 10.

[0102] In some embodiments, referring to FIG. 2, at least one electrode sheet 11 contacts the solid-state electrolyte 121. In an embodiment, the cathode 111 contacts the solid-state electrolyte 121. In an embodiment, the anode 112 contacts the solid-state electrolyte 121. In an embodiment, both the cathode 111 and the anode 112 contact the solid-state electrolyte 121.

[0103] In this embodiment, at least one electrode sheet 11 contacts the solid-state electrolyte 121, which can reduce the distance between the cathode 111 and the anode 112, improve the working efficiency of the electrode assembly 10, and reduce energy consumption.

[0104] In some embodiments, referring to FIG. 1, the projection of the electrode sheet 11 in a plane perpendicular to the first direction is within the projection range of the solid-state electrolyte 121. That is, the projection of the cathode 111 and the projection of the anode 112 are both within the projection range of the solid-state electrolyte 121, the anode 112 and the cathode 111 are completely blocked by the solid-state electrolyte 121, and the anode 112 and the cathode 111 do not contact. The size of the solid-state electrolyte 121 is greater than or equal to the size of the electrode sheet 11, which not only can reduce the probability of contact between the cathode 111 and the anode 112 as much as possible, improve reliability and safety, but also facilitates the rapid and effective transfer of ions by the solid-state electrolyte 121.

[0105] In the related art, an electrolytic device includes an electrode sheet for electrolyzing a fluid. In some cases, the effective area of the electrode sheet is too small to meet the laundry cleaning standards such as wash ratio and color protection requirements. In other cases, the effective area of the electrode sheet is too large, the power of the electrolytic device increases, resulting in an increase in the power of the entire machine, which requires a large power supply line to be matched.

[0106] In some embodiments, referring to FIGS. 4-6, the electrode sheet 11 forms a through hole 11a that penetrates both sides of the electrode sheet 11 along the first direction, and the effective area of at least one side of the electrode sheet 11 along the first direction is 2 cm 2 to 50 cm 2Water can flow through the electrode sheet 11 via the through holes 11a to reduce the resistance during water flow. In this way, the electrolysis efficiency of the electrolysis device 100 is higher, and the washing ratio and color protection requirements of the clothes can be met.

[0107] It should be noted that the effective area refers to the area of one side of the electrode sheet 11 along the first direction minus the remaining area after subtracting the total area of the through holes 11a. The total area of the through holes 11a refers to the sum of the areas of all through holes 11a on the side. For example, one side of the electrode sheet 11 along the first direction can be rectangular, the electrode sheet 11 includes a plurality of through holes 11a, and each of the plurality of through holes 11a can be circular. The effective area of the electrode sheet 11 refers to the remaining area after subtracting the sum of the areas of the plurality of circles from the rectangular area.

[0108] It should be noted that in this application, the unit "cm 2 " is square centimeters, and the plurality refers to a number including two or more.

[0109] It has been found through experiments that when the effective area is less than 2cm 2 , the washing ratio and color protection requirements of the clothes cannot be met. When the effective area is greater than 50cm 2 , the overall power of the clothes treatment device 1000 increases, resulting in increased energy consumption. Please refer to Table 1, which is a table of washing ratio, color protection, and power test results using the electrolysis device 100 of the present application. Compared with related art, the effective area of the electrode sheet 11 in the embodiment of the present application is between 2cm 2 and 50cm 2 . In this way, without the need for a large power supply line, the electrolysis efficiency of the electrolysis device 100 can be improved by increasing the effective area, while meeting the washing ratio and color protection requirements of the clothes. Further, by setting an appropriate effective area, for example, it can be 2cm 2 , 5cm 2 , 10cm 2 , 15cm 2 , 20cm 2 , 25cm 2 , 30cm 2 , 35cm 2 , 40cm 2 , 45cm 2 , or 50cm 2 , etc., to adapt to different types of clothes treatment devices 1000.

[0110] Table 1

[0111] The washing ratio refers to the degree of cleanliness of the clothes. It should be noted that a washing ratio of no less than 1.1 meets industry standards, and a color protection of greater than 1.5 can be considered qualified.

[0112] In one embodiment, the ratio of the total area of the through holes 11a to the area of one side of the electrode sheet 11 along the first direction is 10% to 30%. For example, the ratio can be 10%, 15%, 20%, 25%, or 30%, etc. By setting an appropriate ratio, the number of through holes 11a, the flow area, and the effective area of the electrode sheet 11 are moderate, meeting the cleaning requirements and power requirements, and improving the electrolysis efficiency of the electrolysis device 100.

[0113] In one embodiment, referring to FIG. 1, the electrode sheet 11 is an axisymmetric structure. In this way, the through holes 11a are relatively uniformly distributed on the electrode sheet 11, which can reduce the resistance during the flow of the water, so that the water can flow stably and uniformly, and the electrolysis efficiency of the electrolysis device 100 is improved.

[0114] In some embodiments, referring to FIGS. 4 to 6, the electrolysis device 100 includes two clamping pieces 20, and the electrode assembly 10 is clamped between the two clamping pieces 20. The clamping pieces 20 have a limiting and fixing effect on the electrode assembly 10. For example, referring to FIG. 5, the electrode assembly 10 can be stacked between the two clamping pieces 20, so that the electrode assembly 10 can be prevented from loosening and falling off, thereby improving the connection stability of the electrode assembly 10 and the two clamping pieces 20.

[0115] In some embodiments, referring to FIGS. 4 and 6, the clamping piece 20 includes a clamping plate 21, and the clamping plates 21 of the two clamping pieces 20 are located on both sides of the electrode assembly 10 along the first direction.

[0116] For example, referring to FIG. 6, for the convenience of description, the clamping plates 21 of the two clamping pieces 20 are defined as a first clamping plate 21b and a second clamping plate 21c, respectively, and the first clamping plate 21b, the electrode assembly 10, and the second clamping plate 21c are stacked along the first direction. For example, the first clamping plate 21b and the second clamping plate 21c can each have a plate structure. In this way, the contact area between the electrode assembly 10 and the clamping piece 20 can be increased, the first clamping plate 21b and the second clamping plate 21c can effectively clamp the electrode assembly 10, and the connection stability of the electrode assembly 10 and the clamping piece 20 is enhanced.

[0117] The plate structure can be a flat plate structure or a curved plate structure.

[0118] In some embodiments, referring to FIG. 4, the clamping plate 21 is formed with a liquid passage gap 21a penetrating through both sides of the clamping plate 21 along the first direction. The liquid passage gap 21a is used for water flow, and the water can flow through the liquid passage gap 21a to contact the electrode sheet 11.

[0119] In some embodiments, referring to FIG. 4, the projection of the through hole 11a in a plane perpendicular to the first direction is located within the projection range of the liquid passage gap 21a. That is, the through hole 11a is in communication with the liquid passage gap 21a, so that the clamping plate 21 does not block the water liquid from flowing to the electrode sheet 11 and the solid-state electrolyte 121, and the water liquid can smoothly contact the electrode assembly 10.

[0120] In some embodiments, referring to FIG. 4, the clamping plate 21 includes a frame 211 and a reinforcing rib 212. The frame 211 surrounds to form an avoiding space 211a, and the reinforcing rib 212 is arranged in the avoiding space 211a and connected with the frame 211. The reinforcing rib 212 divides the avoiding space 211a into a plurality of liquid passage gaps 21a. The frame 211 and the reinforcing rib 212 can contact the electrode sheet 11, and play a role of clamping the electrode assembly 10. The avoiding space 211a can be used for flowing water liquid, so that the water liquid contacts the electrode sheet 11 through the avoiding space 211a.

[0121] In this embodiment, the frame 211 can abut against the peripheral part of the electrode sheet 11, so that the peripheral part of the electrode sheet 11 is subjected to the clamping force. The reinforcing rib 212 is used for optimizing stress distribution and transmission, and plays a role of strengthening the strength of the frame 211. The reinforcing rib 212 can also abut against the middle part of the electrode sheet 11 to improve the clamping effect.

[0122] For example, referring to FIG. 4, the clamping plate 21 includes at least two intersecting reinforcing ribs 212. The two reinforcing ribs 212 divide the avoiding space 211a into a plurality of liquid passage gaps 21a with substantially the same area. In this way, the flow and flow rate of the water liquid through each liquid passage gap 21a are substantially the same, so that the water liquid can stably and uniformly flow. In addition, the frame 211 and the two reinforcing ribs 212 jointly form a hollow structure. The clamping plate 21 in the hollow structure is easy to process and form, and is beneficial to the stability of its own structure.

[0123] In some embodiments, referring to FIG. 5, the clamping piece 20 includes a fastener 22 and a fixing lug 23 connected with the clamping plate 21. The fastener 22 penetrates the fixing lugs 23 of the two clamping pieces 20. The two clamping pieces 20 are assembled and fixed through the fixing lugs 23 and the fastener 22, which is convenient to operate and improves the assembly efficiency.

[0124] The type of the fastener 22 is not limited. For example, the fastener 22 can be a bolt or the like. Taking the bolt as an example, the distance between the two fixing lugs 23 can be adjusted by adjusting the bolt and the nut, so as to adjust the clamping force of the clamping piece 20.

[0125] In some embodiments, referring to FIGS. 4 and 5, the fixing ears 23 are connected to the periphery of the clamping plates 21. For example, the fixing ears 23 are connected to the periphery of the frames 211, so that the fixing ears 23 do not block the liquid passages 21a, and water can flow through the liquid passages 21a and contact the electrode assemblies 10, thereby improving the electrolysis efficiency of the electrolysis device 100. In addition, the periphery of the frames 211 has a large mounting space, facilitating the assembly of the two clamping members 20 and improving the assembly efficiency.

[0126] In an embodiment, referring to FIG. 5, a plurality of fixing ears 23 are distributed along the periphery of the clamping plates 21, and the fixing ears 23 of the two clamping members 20 correspond to each other. In this way, the connection stability of the two clamping members 20 can be further improved, and the two clamping members 20 can be prevented from being offset and misaligned.

[0127] In some embodiments, referring to FIG. 5, the electrolysis device 100 includes an insulating member 30, and the fixing ears 23 of the two clamping members 20 are provided with an insulating member 30 therebetween. For example, referring to FIG. 5, the insulating member 30 is sleeved on the portion of the fastener 22 located between the two fixing ears 23. In this way, on the one hand, the insulating member 30 can prevent the two clamping members 20 from contacting or colliding, and can play a role in insulating and protecting the electrolysis device 100, thereby preventing the two clamping members 20 from being in contact and short-circuiting. On the other hand, the fastener 22 has a limiting effect on the insulating member 30, preventing the insulating member 30 from loosening and falling off, and improving the stability of the insulating member 30.

[0128] In some embodiments, referring to FIGS. 4 and 5, the clamping member 20 includes an electrical connection part 24, and the electrical connection part 24 is used to be connected to a power supply circuit. For example, the electrical connection part 24 is connected to the clamping plate 21. The electrical connection part 24 conducts electrical energy to the electrode sheet 11 through the clamping plate 21. That is, the electrical energy of the power supply circuit is conducted to the electrode sheet 11 through the clamping member 20, and the electrode sheet 11 is electrically connected to the external power supply circuit through the clamping member 20. The electrical connection parts 24 of the two clamping members 20 are respectively electrically connected to the positive and negative electrodes of the power supply circuit to form an electrical loop.

[0129] In an embodiment, referring to FIG. 4, the electrical connection part 24 is connected to the periphery of the clamping plate 21. For example, the electrical connection part 24 is connected to the periphery of the frame 211, so that the electrical connection part 24 does not block the liquid passages 21a, and water can flow through the liquid passages 21a and contact the electrode assemblies 10, thereby improving the electrolysis efficiency of the electrolysis device 100.

[0130] In addition, the electrical connection part 24 is spaced apart from the fixing ear 23, which can also reduce the probability of the external power line contacting other parts and reduce the safety hazard.

[0131] In an embodiment, please refer to FIG. 4, in a plane perpendicular to the first direction as a projection plane, the projections of the contact parts 24 of the two clamping members 20 do not overlap. That is, the projections of the two contact parts 24 are spaced apart, so that the two contact parts 24 are far apart, avoiding short circuit caused by water impact or other forces.

[0132] In some embodiments, the electrode sheet 11 is in conductive contact with the clamping member 20. That is, the clamping member 20 can conduct current, and the current is transmitted to the electrode sheet 11 through the clamping member 20 to realize the electrification of the electrode sheet 11. In this way, on the one hand, the electrode sheet 11 and the clamping member 20 have a large contact area, which can reduce power loss and improve conductive efficiency. On the other hand, it can also reduce the additional components required for the electrification of the electrode sheet 11 and reduce production costs.

[0133] The clamping member 20 includes but is not limited to a metal member, which has low resistance and good conductive performance.

[0134] In some embodiments, please refer to FIGS. 7-9, the electrolysis device 100 includes a housing 40, the housing 40 is formed with a liquid inlet 40a, a liquid outlet 40b and a flow cavity 40c, the liquid inlet 40a and the liquid outlet 40b are in communication with the flow cavity 40c, and at least part of the electrode assembly 10 is located in the flow cavity 40c. The water enters the flow cavity 40c from the liquid inlet 40a, the electrode assembly 10 electrolyzes the water flowing through the flow cavity 40c, and the electrolyzed water flows out from the liquid outlet 40b. The liquid inlet 40a is convenient for connecting a water source, for example, the liquid inlet 40a and the water valve of the clothes treatment equipment 1000 can be connected through a pipeline or other structural member. The liquid outlet 40b is convenient for connecting a clothes treatment cavity, for example, the liquid outlet 40b and the clothes treatment cavity can be connected through a pipeline or other structural member. The housing 40 not only facilitates the concentration of water flowing through the electrode assembly 10, thereby improving the electrolysis efficiency, but also protects the electrode assembly 10.

[0135] In some embodiments, please refer to FIGS. 7 and 8, the liquid inlet 40a is formed on one side of the housing 40 along the second direction, and the liquid outlet 40b is formed on the lower surface of the housing 40, which is convenient for the smooth discharge of the electrolyzed water from the flow cavity 40c, and the second direction, the up-down direction and the first direction are perpendicular to each other.

[0136] For example, the water solution enters the flow cavity 40c in the second direction, and the electrolyzed water solution is discharged from the flow cavity 40c in the up-down direction. In this way, on the one hand, the impact of the water solution can be reduced, and the water solution can be prevented from flowing too fast and / or having too large a flow rate, so as to prevent the electrode assembly 10 from being damaged. On the other hand, the flow direction of the water solution entering and exiting the flow cavity 40c is changed, the flow rate of the water solution in the flow cavity 40c is reduced, and the residence time of the water solution in the flow cavity 40c is prolonged, so that the electrode assembly 10 can sufficiently electrolyze the water solution. On the other hand, the liquid outlet 40b is formed on the lower surface of the shell 40, and water can be prevented from accumulating in the flow cavity 40c.

[0137] It should be noted that down refers to the direction toward the ground, and up is the opposite direction of down. The first direction, the second direction, and the up-down direction together constitute a three-dimensional vertical coordinate system.

[0138] In some embodiments, referring to FIG. 9, the shell 40 includes a shell body 41 and a shell cover 42, and the shell cover 42 covers the shell body 41 to jointly define the flow cavity 40c. For example, the liquid inlet 40a and the liquid outlet 40b can both be formed on the shell body 41.

[0139] In some embodiments, referring to FIG. 9, the shell body 41 has an opening 40c1 facing upward, and the shell cover 42 covers the shell body 41 and covers the opening 40c1. In this way, on the one hand, the shell cover 42 can prevent foreign matter from entering the flow cavity 40c, thereby protecting the electrode assembly 10; and the shell cover 42 covering the opening 40c1 can also prevent the water solution from overflowing. On the other hand, the electrode assembly 10 can enter and exit the shell body 41 through the opening 40c1, thereby facilitating the assembly and disassembly of the electrode assembly 10 and facilitating maintenance.

[0140] The shell body 41 and the shell cover 42 can be detachably connected or non-detachably connected. For example, the shell body 41 and the shell cover 42 can be welded, screwed, or clamped. The connection between the shell body 41 and the shell cover 42 can be sealed, thereby preventing the water solution in the flow cavity 40c from leaking.

[0141] The number of the electrode sheets 11 is at least two. That is, the number of the electrode sheets 11 is two or more.

[0142] In some embodiments, the electrode assembly 10 includes two electrode sheets 11, one of which is a cathode 111 and the other of which is an anode 112. In some embodiments, the electrode assembly 10 includes more than two electrode sheets 11. The cathode 111 and the anode 112 form an electrolysis group, and a solid-state electrolyte 121 can be arranged between the cathode 111 and the anode 112 of each electrolysis group. There can be one or more electrolysis groups. For example, a plurality of electrolysis groups can be stacked in the first direction. For another example, a plurality of electrolysis groups can be tiled in a plane perpendicular to the first direction.

[0143] In some embodiments, referring to FIG. 1, the electrode sheet 11 has an axisymmetric shape, and the at least two through holes 11a are symmetrically distributed along the axis of symmetry of the electrode sheet 11. In this way, the through holes 11a are relatively uniformly distributed on the electrode sheet 11, which can reduce the resistance during the flow of the water solution, so that the water solution can flow stably and uniformly, thereby improving the electrolysis efficiency of the electrolysis device 100.

[0144] In some embodiments, referring to FIG. 1, the electrode sheet 11 has an axisymmetric structure. That is, all the through holes 11a are symmetric along the axis of symmetry of the electrode sheet 11. In this way, the through holes 11a are relatively uniformly distributed on the electrode sheet 11, which further improves the stability and uniformity of the water solution during the flow, thereby improving the electrolysis efficiency of the electrolysis device 100.

[0145] The shape of the through hole 11a is not limited. For example, the shape of the through hole 11a can be circular, waist-round, oval, polygonal, or irregular, etc.

[0146] Referring to FIGS. 1, 2, and 4-6, the clamping member 20 is formed with a clamping space, and the electrode assembly 10 is arranged in the clamping space.

[0147] The clamping space has a limiting and fixing effect on the electrode assembly 10. For example, the clamping member 20 can have an integrated structure, and the clamping member 20 is internally formed with a clamping space. In this way, the electrode assembly 10 and the clamping member 20 can be assembled, which can prevent the electrode assembly 10 from loosening and falling off, thereby improving the connection stability of the electrode assembly 10 and the clamping member 20.

[0148] In this embodiment, the electrode assembly 10 is arranged in the clamping space, which has a simple assembly mode and can effectively prevent the electrode assembly 10 from loosening and falling off, thereby improving the connection stability of the electrode assembly 10 and the clamping member 20.

[0149] In some embodiments, the clamping plate 21 and the power connection part 24 are an integrated structure, that is, the clamping member 20 can be an integrated structure. In this way, the process of separately manufacturing the power connection part 24 can be reduced, and the production efficiency can be improved.

[0150] Referring to FIG. 10, the laundry treating apparatus 1000 includes a water valve and a first liquid path 200.

[0151] The water valve can be used to connect with a water source. The water source includes, but is not limited to, a tap water pipe, etc. In an embodiment, the water valve can be used to connect with the tap water pipe, and the water valve can be a water inlet control valve of the entire laundry treating apparatus 1000. That is, the water valve can be used to provide water for the washing, rinsing, etc. of the entire laundry treating apparatus 1000.

[0152] The first liquid path 200 is connected with the water valve and the laundry treatment cavity, and the electrolysis device 100 is arranged in the first liquid path 200. The water valve can open or cut off the water from the water source to enter the first liquid path 200. The first liquid path 200 conveys the water from the water valve to the laundry treatment cavity after the water is electrolyzed by the electrolysis device 100.

[0153] In this embodiment, the water valve can provide water to the electrolysis device 100, and the water can flow through the electrolysis device 100 through the first liquid path 200. In this way, the electrolysis device 100 has less contact or even no contact with the washing water from the laundry treatment cavity, which can avoid the attachment of impurities such as lint to the electrode assembly 10, reduce the risk of the electrode sheet 11 contacting the lint, and improve the electrolysis efficiency of the electrode sheet 11. After the water is electrolyzed by the electrolysis device 100, hydroxyl radicals and / or ozone and other substances are generated, and the electrolyzed water enters the laundry treatment cavity. The hydroxyl radicals and / or ozone and other substances with strong oxidation activity can play a role in sterilization and disinfection of the laundry and prevention of color transfer. Hydrogen micro-bubbles can assist the detergent in removing dirt such as sebum, oil, and small dust accumulated inside the fibers of the laundry, which can improve the cleaning ratio.

[0154] In one embodiment, referring to FIGS. 10 and 14, the laundry treatment apparatus 1000 includes a detergent box 300, which is arranged in the first liquid path 200 and located downstream of the electrolysis device 100. Part of the cavity of the detergent box 300 is part of the first liquid path 200. The water electrolyzed by the electrolysis device 100 can first flow through the detergent box 300 and then enter the laundry treatment cavity. By using the cavity of the detergent box 300 as part of the first liquid path 200, the cost can be reduced by saving the pipe. The detergent box 300 is located downstream of the electrolysis device 100, which can avoid the contact between the detergent and the electrode assembly 10 and prevent the electrode sheet 11 from being contaminated and scaled due to the contact between the electrode assembly 10 and the detergent. The influence of the detergent in the detergent box 300 on the electrolysis device 100 can be reduced.

[0155] The detergent box 300 is used to dispense the detergent to the laundry treatment cavity.

[0156] The type of the detergent is not limited, and the detergent includes but is not limited to a cleaning agent, a softening agent, or a scenting agent, etc. The cleaning agent is used to clean the laundry. The softening agent is used to soften, fluff, and eliminate static electricity of the laundry. The scenting agent is used to increase the scent of the laundry. The cleaning agent can be a liquid laundry detergent or a granular laundry detergent, etc.

[0157] In one embodiment, the detergent box 300 is formed with a liquid flow channel, and the first liquid path 200 can flow through the liquid flow channel. That is, the liquid flow channel is part of the first liquid path 200.

[0158] In one embodiment, the detergent box 300 includes a box cover and a box body, and the box cover covers the upper opening of the box body to define a placement cavity. The liquid flow channel can be formed in the box cover.

[0159] In an embodiment, the laundry treatment apparatus 1000 includes the detergent box 300 and a second liquid path connecting the water valve and the laundry treatment cavity, and the detergent box 300 is disposed in the second liquid path. Water from the water valve passes through the first liquid path 200 to the electrolysis device 100, and water from the water valve passes through the second liquid path to the detergent box 300, and the electrolyzed water of the electrolysis device 100 and the water passing through the detergent box 300 do not affect each other. In this way, the electrolysis device 100 can be flexibly arranged, and the fluid path between the electrolysis device 100 and the laundry treatment cavity can be shortened.

[0160] In an embodiment, referring to FIG. 10, the laundry treatment apparatus 1000 includes the detergent box 300, and the electrolysis device 100 is located at the rear side of the detergent box 300. The electrolysis device 100 and the detergent box 300 are reasonably arranged, and the space in the cabinet can be fully utilized.

[0161] In an embodiment, the water valve is located at the rear side of the electrolysis device 100. The electrolysis device 100 is located between the water valve and the detergent box 300. If the electrolysis device 100 and the detergent box 300 are both disposed in the first liquid path 200, the distance between the electrolysis device 100 and the water valve is relatively short, and the first liquid path 200 can be conveniently routed.

[0162] In an embodiment, the electrolysis device 100 is located above the drum assembly. The electrolysis device 100 is placed in the space above the drum assembly. The space in the drum assembly is part of the laundry treatment cavity.

[0163] In an embodiment, referring to FIGS. 11 to 18, the fluid of the first liquid path 200 sequentially passes through the liquid inlet 40a, the flow-through cavity 40c, and the liquid outlet 40b. For example, water from the water valve enters the flow-through cavity 40c from the liquid inlet 40a, the electrode assembly 10 electrolyzes the water passing through the flow-through cavity 40c, and the electrolyzed water flows out from the liquid outlet 40b. The electrode assembly 10 is exposed in the flow-through cavity 40c, and the shell 40 not only facilitates the water to flow through the electrode assembly 10, thereby improving the electrolysis efficiency, but also protects the electrode assembly 10.

[0164] In an embodiment, the laundry treatment apparatus 1000 includes a dispenser box having a detergent dispensing cavity, and the dispenser box is pullably disposed in the detergent box 300. For example, the dispenser box is pullably disposed in the placement cavity. The detergent dispensing cavity is used for dispensing detergent. The dispenser box is pulled out from the detergent box 300 to at least partially outside the detergent box 300, and a user can dispense detergent into the detergent dispensing cavity. The detergent box 300 can have a mixing cavity, and the detergent and water can be mixed in the mixing cavity. For example, the region below the dispenser box can be the mixing cavity.

[0165] In one embodiment, the detergent box 300 is formed with a discharge port which is in communication with the mixing chamber. The discharge port is used to discharge the detergent mixture solution in the mixing chamber to the laundry treatment chamber.

[0166] In one embodiment, the liquid flow channel can be located above the mixing chamber, and the liquid flow channel and the mixing chamber are independent of each other. That is, the electrolyzed water in the liquid flow channel does not enter the mixing chamber, and the detergent mixture solution in the mixing chamber does not enter the liquid flow channel.

[0167] In one embodiment, the first liquid path 200 includes a first pipe which connects the water valve and the liquid inlet 40a. The water from the water valve enters the flow chamber 40c through the first pipe and the liquid inlet 40a. The first pipe is a part of the first liquid path 200.

[0168] In one embodiment, referring to FIGS. 10 to 13, the first liquid path 200 includes a second pipe 210 which connects the liquid outlet 40b and the inlet of the liquid flow channel, and a third pipe 220 which connects the outlet of the liquid flow channel and the laundry treatment chamber. The electrolyzed water in the flow chamber 40c enters the laundry treatment chamber through the second pipe 210, the liquid flow channel and the third pipe 220 in sequence. The first pipe, the flow chamber 40c, the second pipe 210, the liquid flow channel and the third pipe 220 can constitute the first liquid path 200.

[0169] In one embodiment, referring to FIG. 10, the water outlet end of the third pipe 220 is connected to the door seal ring 500. For example, the water outlet end of the third pipe 220 can extend to the radial inner side of the door seal ring 500. In this way, the electrolyzed water can directly enter the laundry treatment chamber through the space surrounded by the door seal ring 500 without the need for an intermediate pipe to guide the liquid again.

[0170] In some embodiments, a fourth pipe connects the liquid outlet 40b and the laundry treatment chamber. In this way, the first pipe, the flow chamber 40c and the fourth pipe can constitute the first liquid path 200. The first liquid path 200 can not pass through the detergent box 300.

[0171] It can be understood that part of the fourth pipe can be fixed to the detergent box 300, for example, the fourth pipe is fixed to the detergent box 300 by clamping.

[0172] For example, in one embodiment, referring to FIGS. 10, 11 and 15, the cathode 111 and the anode 112 are stacked along the left-right direction, and the liquid inlet 40a can be formed on the rear side of the shell 40.

[0173] In this embodiment, the water from the water valve flows into the flow cavity 40c through the inlet 40a in the second direction, and the electrolyzed water in the flow cavity 40c flows out through the outlet 40b. In the flow cavity 40c, the water flows in the second direction relative to the electrode assembly 10, so that the water continuously flows through the electrode assembly 10 and carries away the products such as ozone, hydroxyl radicals and hydrogen.

[0174] In one embodiment, as shown in FIGS. 11 and 12, the axis of the outlet 40b intersects the up-down direction. The axis of the outlet 40b refers to the line connecting the center points of the flow sections of the outlet 40b. For example, when the flow section of the outlet 40b is circular, the axis of the outlet 40b is the line connecting the centers of the circles. The axis of the outlet 40b intersects the up-down direction, that is, the outlet 40b extends obliquely relative to the up-down direction.

[0175] In one embodiment, the outlet 40b can be located on the side of the electrode sheet 11 away from the inlet 40a in the second direction. In this way, the fluid from the inlet 40a can flow completely through the electrode sheet 11 in the second direction, and the water can fully contact the electrode sheet 11 before flowing out of the outlet 40b.

[0176] In one embodiment, the support framework 122 can be made of an insulating material.

[0177] In some embodiments, the through hole 11a is a long strip-shaped hole, and the through hole 11a can extend into a long strip-shaped hole in a direction intersecting the second direction.

[0178] In some embodiments, as shown in FIGS. 11 and 18, part of the electrical connection portion 24 extends out of the housing 40. For example, part of the electrical connection portion 24 extends out of the upper surface of the housing 40. In this way, the electrical connection end of the power supply circuit can be connected to the electrical connection portion 24, and the water in the flow cavity 40c can be prevented from contacting the electrical connection end to some extent.

[0179] It can be understood that the housing 40 has a mounting hole 40d for the electrical connection portion 24, and the mounting hole 40d and the electrical connection portion 24 are sealed. In this way, the water in the flow cavity 40c can be prevented from contacting the electrical connection end, and the safety is improved.

[0180] In some embodiments, as shown in FIGS. 14, 15 and 18, one end of the electrical connection portion 24 is connected to one side of the clamping plate 21 in the second direction, and the other end of the electrical connection portion 24 is bent upward. When a plane perpendicular to the first direction is taken as a projection plane, the projection of the electrical connection portion 24 is substantially L-shaped.

[0181] In some embodiments, as shown in FIG. 13, the mounting hole 40d can be formed in the cover 42.
