[0041] The following further describes the implementation manners of the present application in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0042] In the various specific technical features and each embodiment described in the specific implementation manners, without conflict, they can be combined in any suitable manner. For example, different embodiments can be formed by combining different specific technical features / embodiments. To avoid unnecessary repetition, various possible combination manners of the various specific technical features / embodiments in the present application will not be described separately. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] In the related art, the cathode and anode of the electrolysis device are arranged at intervals, that is to say, a distance must be reserved between the cathode and the anode. During the process of electrolyzing the aqueous solution at the cathode and anode, it relies on the ions in the aqueous solution to conduct electricity, and the water quality varies greatly in different regions. For example, the TDS of the water quality in Wuxi is about 150, while it is as high as 500 in northern regions such as Xinjiang; the TDS in Japan is about 80, while it is more than 500 in Europe and North America. TDS (Total Dissolved Solids) refers to the concentration of total dissolved substances in water, which mainly reflects the concentration of calcium, magnesium and other ions in water, and has a good corresponding relationship with the water hardness and conductivity. Exemplarily, the smaller the TDS value, the lower the concentration of calcium, magnesium and other ions in water, and the smaller the conductivity. The water quality difference will lead to two extreme situations. The first situation: the TDS of the aqueous solution is too low, approaching pure water, the ions in the aqueous solution are too low to conduct electricity, resulting in the inability of the electrolyzed water device to electrolyze. The second situation: the TDS is too high, the water quality is too hard, and the power of the anode and cathode rises sharply, resulting in short-circuit protection, and the anode and cathode decay rapidly due to scale. Therefore, the TDS difference in water quality leads to unstable electrolyzed water effects.

[0044] In a first aspect of the embodiments of the present application, an electrolysis device 100 is provided, and the electrolysis device 100 can be used for a clothing treatment device.

[0045] Please refer to Figures 1 to 9 , the electrolysis device 100 includes an electrode assembly 10, the electrode assembly 10 includes a solid electrolyte 121, a support skeleton 122 and electrode sheets 11, the solid electrolyte 121 is arranged on the support skeleton 122; at least one electrode sheet 11 is a cathode 111, at least one electrode sheet 11 is an anode 112, the cathode 111 and the anode 112 are stacked along a first direction, and the solid electrolyte 121 is arranged between the cathode 111 and the anode 112.

[0046] The solid electrolyte 121 is in a solid state and has an ion transport function. Both the cathode 111 and the anode 112 can be prepared from materials known in the art that can be used for electrolysis.

[0047] The solid electrolyte 121 is used to allow the migration of at least one of anions and cations. The support skeleton 122 is used to enhance the mechanical strength of the solid electrolyte 121. The solid electrolyte 121 is not easily punctured, which helps to reduce the risk of internal short circuit. In addition, the solid electrolyte 121 is not easily damaged during the assembly of the electrolysis device 100.

[0048] The type of the solid electrolyte 121 is not limited. The solid electrolyte 121 can be a proton membrane for the migration of hydrogen ions, or the solid electrolyte 121 can be other types of solid membranes. For example, the solid electrolyte 121 can be a solid polymer electrolyte membrane (SPEM).

[0049] The electrode assembly 10 is used for electrolyzing a fluid. The fluid can be an aqueous solution. This application takes the fluid as an aqueous solution as an example for illustration. The electrode assembly 10 can be used to electrolyze the aqueous solution to generate substances such as hydroxyl radicals and / or ozone with strong oxidation activity.

[0050] Principle of the electrode assembly 10 for electrolyzing water: A solid electrolyte 121 is arranged between the cathode 111 and the anode 112. The solid electrolyte 121 separates the cathode 111 and the anode 112 and can transfer ions. During the process of the electrode assembly 10 electrolyzing the aqueous solution, water molecules ionize to generate cations and anions, and at least one of the cations and anions can migrate through the solid electrolyte 121. For example, hydrogen ions can migrate through the solid electrolyte 121, and high-concentration cation regions and anion regions are respectively formed on both sides of the solid electrolyte 121 in the first direction. Substances such as hydroxyl radicals and / or ozone with strong oxidation activity are generated on the surface of the anode 112, and hydrogen is generated on the surface of the cathode 111.

[0051] Ozone can sterilize or inhibit bacteria on clothes, etc. Ozone can also oxidize and destroy the chromogenic groups of dye molecules that have dissociated into the water to decolorize the dyes, prevent the free dyes from staining light-colored clothes to cause color bleeding, and continue to react to decompose the dye molecules into harmless carbon dioxide, water, and / or inorganic salts without secondary pollution, playing a role in preventing color bleeding.

[0052] Hydroxyl radicals (·OH) have an extremely high oxidation potential (2.80 eV), with extremely strong oxidation ability. They can sterilize or inhibit bacteria on clothing, etc. Hydroxyl radicals can undergo rapid chain reactions with most organic pollutants, oxidizing harmful substances into carbon dioxide, water, or inorganic salts without selectivity and without secondary pollution. Hydroxyl radicals can also oxidize and destroy free dyes to decolorize the dyes, playing a role in preventing color bleeding.

[0053] The cathode 111 will generate hydrogen microbubbles. Since the diameter of the microbubbles is very small, usually not greater than 50 μm (micrometers), the hydrogen microbubbles can well enter the interior of the clothing fibers during the washing process. Through the actions of microbubble bursting, adsorption and floating, etc., the microbubbles circulate and scour the clothing, assisting the detergent to remove dirt such as sebum, grease, and tiny dust accumulated inside the clothing fibers, and can improve the washing ratio.

[0054] It should be noted that the superposition of the cathode 111 and the anode 112 along the first direction means that the anode 112 and the cathode 111 are arranged roughly face to face. Exemplarily, please refer to Figure 1 and Figure 2 , the cathode 111, the anode 112, and the solid electrolyte 121 are all roughly in a flat plate structure. The anode 112, the solid electrolyte 121, and the cathode 111 are stacked in sequence along the first direction. That is to say, the anode 112, the solid electrolyte 121, and the cathode 111 are arranged roughly parallel face to face. In this way, without the anode 112 and the cathode 111 contacting and short - circuiting, the distance between the two poles can be reduced as much as possible, reducing energy consumption and improving the electrolysis efficiency of the electrolysis device 100.

[0055] For the electrolysis device 100 provided in the embodiment of the present application, on the one hand, the solid electrolyte 121 is arranged between the anode 112 and the cathode 111, which can prevent the anode 112 and the cathode 111 from contacting and short - circuiting; the solid electrolyte 121 can transfer ions and can conduct electricity without relying on ions in the water solution, thus avoiding the influence of water quality on the power of the electrode sheet 11. On the other hand, the solid electrolyte 121 is used for at least one of the migration of anions and cations, and the support skeleton 122 is used to enhance the mechanical strength of the solid electrolyte 121. The solid electrolyte 121 is not easily punctured and is not easily damaged during the assembly process of the electrolysis device 100.

[0056] In the second aspect of the embodiment of the present application, a clothing treatment device is provided, including a clothing treatment cavity and the electrolysis device 100 in any embodiment of the present application. The fluid after electrolysis of the electrode assembly 10 enters the clothing treatment cavity.

[0057] The clothing treatment cavity can be used to hold clothing.

[0058] The laundry treatment device provided by the embodiment of the present application electrolyzes the aqueous solution through the electrolysis device 100 to generate substances such as hydroxyl radicals and / or ozone. The electrolyzed aqueous solution enters the laundry treatment chamber. Substances with strong oxidation activity such as hydroxyl radicals and / or ozone play a role in sterilizing and disinfecting the laundry and preventing color bleeding. Hydrogen microbubbles can assist the detergent in removing dirt such as sebum, grease, and fine dust accumulated inside the laundry fibers, and can improve the washing ratio.

[0059] Exemplarily, the laundry treatment device has a first liquid path communicating with the laundry treatment chamber. The first liquid path can communicate with a water source to supply water to the laundry treatment chamber. In this way, the laundry treatment device has a laundry washing function. The electrolysis device 100 is arranged on the first liquid path to electrolyze the aqueous solution flowing into the laundry treatment chamber.

[0060] The water source can be a tap water source or the circulating water of the laundry treatment device. That is to say, the aqueous solution can be tap water. Tap water does not contain impurities such as laundry lint and hair, which can avoid the attachment of impurities such as lint to the electrode assembly 10 and improve the service life of the electrolysis device 100.

[0061] The functions of the laundry treatment device are not limited. Exemplarily, in addition to the washing function, the laundry treatment device can also have a drying function. The drying function can be used to dry the laundry.

[0062] The laundry treatment device can be a washing machine or a washer-dryer, etc. A washer-dryer is a laundry treatment device integrating washing and drying functions.

[0063] The laundry treatment device can include a cylinder assembly. The axis of the cylinder assembly can extend in the horizontal direction. The laundry treatment device in this embodiment is also called a drum-type laundry treatment device. The axis of the cylinder assembly can extend in the vertical direction. The laundry treatment device in this embodiment is also called a pulsator-type laundry treatment device.

[0064] In some embodiments, the cylinder assembly includes a rotatable inner cylinder. The inner cylinder has a loading and unloading opening, and the loading and unloading opening can face forward. The inner cylinder can be used to place and process laundry. The user puts or takes out the laundry through the loading and unloading opening from the front. The inner cylinder can rotate. For example, the laundry, aqueous solution, detergent, etc. rotate with the inner cylinder. In this way, the laundry continuously changes its posture inside the inner cylinder, and the fluids such as the aqueous solution and detergent change their flow directions with the inner cylinder.

[0065] In some embodiments, the inner cylinder can be generally in the shape of a hollow cylinder.

[0066] In some embodiments, the barrel assembly includes an outer barrel, and an inner barrel can be disposed in the outer barrel. The outer barrel can be used to hold water, and the inner barrel is used to hold clothes. In this embodiment, water is held in the outer barrel, and the inner barrel can also be referred to as a perforated inner barrel. Fluids can flow between the spaced space between the outer barrel and the inner barrel and the space inside the inner barrel through the flow holes of the inner barrel.

[0067] In some embodiments, the outer barrel can be generally in the shape of a hollow cylinder.

[0068] In some embodiments, the inner barrel holds water by itself and can also be referred to as a non-perforated inner barrel. An outer barrel can be provided outside the non-perforated inner barrel, or an outer barrel can be not provided.

[0069] It can be understood that in some embodiments, the barrel assembly can have only the inner barrel without the above-mentioned outer barrel. In this embodiment, the inner barrel is a non-perforated inner barrel and can hold water by itself. The inner barrel can be a single-barrel structure. That is to say, the laundry treatment device has only one barrel, which is the inner barrel.

[0070] In some embodiments, the laundry treatment device includes a cabinet, the barrel assembly is disposed in the cabinet, and the cabinet is provided with an opening communicating with the inside of the barrel assembly.

[0071] In some embodiments, the cabinet can be generally in the shape of a hexahedron, for example, a cube or a cuboid.

[0072] In some embodiments, the laundry treatment device includes a door body and a door seal ring. The door body is used to selectively open or close the opening of the cabinet. The axis of the barrel assembly extends in the horizontal direction, and the door seal ring can be used to seal the gap between the barrel assembly and the opening of the cabinet. The space surrounded by the door seal ring and the space inside the inner barrel can form a laundry treatment chamber.

[0073] It should be noted that the extending direction of the axis of the door seal ring is the same as the extending direction of the axis of the barrel assembly, and the axis of the door seal ring can extend in the horizontal direction.

[0074] In some embodiments, please refer to Figure 6 , the solid electrolyte 121 covers at least one side surface of the support skeleton 122 along the first direction.

[0075] Exemplarily, in some embodiments, the solid electrolyte 121 covers one side surface of the support skeleton 122 along the first direction. In some other embodiments, the solid electrolyte 121 covers two side surfaces of the support skeleton 122 along the first direction. In some other embodiments, the solid electrolyte 121 covers all outer surfaces of the support skeleton 122.

[0076] In this embodiment, the solid electrolyte 121 is used for allowing at least one of anions and cations to migrate. The support framework 122 is used for enhancing the mechanical strength of the solid electrolyte 121, and the solid electrolyte 121 is not easily punctured, which is beneficial to reducing the risk of internal short circuit. In addition, the solid electrolyte 121 is not easily damaged during the assembly process of the electrolysis device 100.

[0077] It can be understood that the number of layers of the solid electrolyte 121 can be one layer or multiple layers, and the multiple layers include two layers and more than two layers. For example, two layers or three layers, etc.

[0078] In some embodiments, the solid electrolyte 121 and the support framework 122 can be of an integral structure. That is to say, the solid electrolyte 121 can adhere to the support framework 122 by its own acting force.

[0079] In some embodiments, the solid electrolyte 121 and the support framework 122 can be connected by fasteners. The manner in which the solid electrolyte 121 adheres to the support framework 122 is not limited. Exemplarily, the solid electrolyte 121 can adhere to the support framework 122 by means such as coating and deposition.

[0080] In some embodiments, please refer to Figure 3 , the support framework 122 is in a mesh structure. The support framework 122 in a mesh structure is easy to process and form, and is beneficial to the stability of its own structure, thereby enhancing the structural stability of the electrode assembly 10.

[0081] In some embodiments, please refer to Figure 2 , at least one electrode sheet 11 contacts the solid electrolyte 121. In one embodiment, the cathode 111 contacts the solid electrolyte 121. In one embodiment, the anode 112 contacts the solid electrolyte 121. In one embodiment, both the cathode 111 and the anode 112 contact the solid electrolyte 121.

[0082] In this embodiment, at least one electrode sheet 11 contacts the solid 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 the energy consumption.

[0083] In some embodiments, please refer to Figure 1, with a plane perpendicular to the first direction as the projection plane, the projection of the electrode sheet 11 is within the projection range of the solid electrolyte 121. That is to say, the projections of the cathode 111 and the anode 112 are both within the projection range of the solid electrolyte 121. The anode 112 and the cathode 111 are completely blocked by the solid electrolyte 121, and the anode 112 and the cathode 111 do not contact each other. The size of the solid electrolyte 121 is greater than or equal to the size of the electrode sheet 11, which can not only reduce the probability of contact between the cathode 111 and the anode 112 as much as possible, improve reliability and safety, but also facilitate the rapid and effective transfer of ions by the solid electrolyte 121.

[0084] In the related art, in some cases, the effective area of the electrode sheet is too small to meet the clothing washing standards such as the washing ratio and the anti-color bleeding requirements. In other cases, the effective area of the electrode sheet is too large, increasing the power of the electrolysis device, resulting in an increase in the overall power of the machine, and a high-power power cord needs to be matched.

[0085] In some embodiments, please refer to Figures 4 to 6 , the electrode sheet 11 forms a through hole 11a that penetrates through two side surfaces of the electrode sheet 11 along the first direction. The effective area of at least one side surface of the electrode sheet 11 along the first direction is 2 cm 2 to 50 cm 2 . In this way, the electrolysis efficiency of the electrolysis device 100 is relatively high, and the washing ratio and anti-color bleeding requirements of the clothing can be met.

[0086] It should be noted that the effective area refers to the remaining area of the area of one side surface of the electrode sheet 11 along the first direction minus 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 the through holes 11a on this side surface. For example, one side surface of the electrode sheet 11 along the first direction can be rectangular, the electrode sheet 11 includes a plurality of through holes 11a, and the plurality of through holes 11a can all be circular. The effective area of the electrode sheet 11 refers to the remaining area of the rectangular area minus the sum of the areas of the plurality of circular areas.

[0087] It should be noted that in this application, the unit "cm 2 " is square centimeter, and a plurality refers to a quantity including two or more.

[0088] It has been found through experiments that when the effective area is less than 2 cm 2 , the washing ratio and anti-color bleeding requirements of the clothing cannot be met. When the effective area is greater than 50 cm 2 , the overall power of the clothing processing device increases, resulting in an increase in energy consumption. Please refer to Table 1. Table 1 is a table of the test results of the washing ratio, anti-color bleeding, and power using the electrolysis device 100 of this application. Compared with the related art, the effective area of the electrode sheet 11 in the embodiments of this application is between 2 cm 2 to 50 cm 2Thereby, on the basis of not requiring a large-power power cord, the electrolysis efficiency of the electrolysis device 100 can be improved by increasing the effective area, and at the same time, the washing ratio of the clothes and the requirement of preventing color bleeding can be satisfied. Further, by setting an appropriate effective area, for example, it can be 2 cm 2 , 5 cm 2 , 10 cm 2 , 15 cm 2 , 20 cm 2 , 25 cm 2 , 30 cm 2 , 35 cm 2 , 40 cm 2 , 45 cm 2 or 50 cm 2 and so on to adapt to different types of clothing treatment devices.

[0089] Table 1

[0090] <![CDATA[Effective area / cm 2 > Washing ratio Color bleeding prevention Power of electrolysis device 100 / W 2 1.1 1.6 5 10 1.15 2.3 20 20 1.2 3.4 40 35 1.21 5.5 100 50 1.21 6.0 150

[0091] The washing ratio refers to the degree of cleanliness of the clothes after washing. It should be noted that a washing ratio of not less than 1.1 meets the industry standard, and a color bleeding prevention greater than 1.5 can be considered qualified.

[0092] In one embodiment, the ratio of the total area of the through holes 11a to the area of one side of the electrode plate 11 along the first direction is 10% to 30%. Exemplarily, this ratio can be 10%, 15%, 20%, 25% or 30% and so on. By setting an appropriate ratio, the number of the through holes 11a, the current-carrying area, and the effective area of the electrode plate 11 are all moderate, meeting the washing requirements and power requirements, and improving the electrolysis efficiency of the electrolysis device 100.

[0093] In one embodiment, please refer to Figure 1 , the electrode plate 11 has an axisymmetric structure. Thus, the through holes 11a are relatively evenly distributed on the electrode plate 11, which can reduce the resistance during the flow of the water liquid, enabling the water liquid to flow stably and evenly, and improving the electrolysis efficiency of the electrolysis device 100.

[0094] In some embodiments, please refer to Figures 4 to 6 , the electrolysis device 100 includes two clamping members 20, and the electrode assembly 10 is clamped between the two clamping members 20. The clamping members 20 have a limiting and fixing effect on the electrode assembly 10. Exemplarily, please refer to Figure 5 , the electrode assembly 10 can be stacked between the two clamping members 20. Thus, the electrode assembly 10 can be prevented from loosening and falling off, thereby improving the connection stability between the electrode assembly 10 and the two clamping members 20.

[0095] In some embodiments, please refer to Figure 4 andFigure 6 The clamping member 20 includes a clamping plate 21, and the clamping plates 21 of the two clamping members 20 are located on both sides of the electrode assembly 10 along the first direction.

[0096] Exemplarily, please continue to refer to Figure 6 For ease of description, the clamping plates 21 of the two clamping members 20 are respectively defined as a first clamping plate 21b and a second clamping plate 21c, and the first clamping plate 21b, the electrode assembly 10, and the second clamping plate 21c are stacked along the first direction. For example, both the first clamping plate 21b and the second clamping plate 21c can be in a flat plate structure. In this way, the contact area between the electrode assembly 10 and the clamping member 20 can be increased, and the first clamping plate 21b and the second clamping plate 21c can effectively clamp the electrode assembly 10, thereby enhancing the connection stability between the electrode assembly 10 and the clamping member 20.

[0097] In some embodiments, please refer to Figure 4 The clamping plate 21 is formed with a liquid passage notch 21a, and the liquid passage notch 21a penetrates through the two side surfaces of the clamping plate 21 along the first direction. The liquid passage notch 21a is used for the flow of water liquid, and the water liquid can flow through the liquid passage notch 21a to contact the electrode plate 11.

[0098] In some embodiments, please refer to Figure 4 Taking the plane perpendicular to the first direction as the projection plane, the projection of the through hole 11a is within the projection range of the liquid passage notch 21a. That is to say, the through hole 11a communicates with the liquid passage notch 21a. In this way, the clamping plate 21 can be prevented from blocking the water liquid from flowing to the electrode plate 11 and the solid electrolyte 121, so that the water liquid can smoothly contact the electrode assembly 10.

[0099] In some embodiments, please refer to Figure 4 The clamping plate 21 includes a frame 211 and a reinforcing rib 212. The frame 211 encloses to form an avoidance space 211a, and the reinforcing rib 212 is arranged in the avoidance space 211a and connected to the frame 211. The reinforcing rib 212 divides the avoidance space 211a into a plurality of liquid passage notches 21a. The frame 211 and the reinforcing rib 212 can contact the electrode plate 11 and play a role in clamping the electrode assembly 10.

[0100] In this embodiment, the frame 211 can abut against the peripheral part of the electrode plate 11, so that the peripheral part of the electrode plate 11 is subjected to a clamping force. The reinforcing rib 212 is used to optimize the stress distribution and transmission, play a role in strengthening the strength of the frame 211, and can also abut against the middle part of the electrode plate 11 to improve the clamping effect.

[0101] Exemplarily, please continue to refer to Figure 4, the clamping plate 21 includes at least two intersecting reinforcing ribs 212, and the two reinforcing ribs 212 divide the avoidance space 211a into a plurality of liquid passing gaps 21a with substantially the same area. In this way, the flow rate and velocity of the liquid passing through each liquid passing gap 21a are substantially the same, enabling the liquid to flow stably and uniformly. In addition, the frame 211 and the two reinforcing ribs 212 together form a hollow structure. The clamping plate 21 with a hollow structure is easy to process and form, and is beneficial to the stability of its own structure.

[0102] In some embodiments, please refer to Figure 5 , the clamping member 20 includes a fastening member 22 and a fixing ear 23 connected to the clamping plate 21. The fastening member 22 passes through the fixing ears 23 of the two clamping members 20. The two clamping members 20 are assembled and fixed through the fixing ears 23 and the fastening member 22, which is convenient for operation and improves the assembly efficiency.

[0103] The type of the fastening member 22 is not limited. For example, the fastening member 22 can be a bolt or the like.

[0104] In some embodiments, please refer to Figure 4 and Figure 5 , the fixing ear 23 is connected to the periphery of the clamping plate 21. Exemplarily, the fixing ear 23 is connected to the periphery of the frame 211. In this way, the fixing ear 23 does not block the liquid passing gap 21a, and the liquid can flow smoothly through the liquid passing gap 21a and contact the electrode assembly 10, thereby improving the electrolysis efficiency of the electrolysis device 100. In addition, the periphery of the frame 211 has a large installation space, which is convenient for assembling the two clamping members 20 and improves the assembly efficiency.

[0105] In one embodiment, please continue to refer to Figure 5 , a plurality of fixing ears 23 are distributed at intervals along the circumferential direction of the clamping plate 21, and the fixing ears 23 of the two clamping members 20 correspond to each other one by one. In this way, the connection stability between the two clamping members 20 can be further enhanced, and the two clamping members 20 can be prevented from shifting and misaligning.

[0106] In some embodiments, please refer to Figure 5 , the electrolysis device 100 includes an insulating member 30, and an insulating member 30 is arranged between the fixing ears 23 of the two clamping members 20. Exemplarily, please continue to refer to Figure 5 , the insulating member 30 is sleeved on the part of the fastening member 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, playing an insulating and protective role for the electrolysis device 100 and preventing the two clamping members 20 from contacting and short-circuiting. On the other hand, the fastening member 22 has a limiting effect on the insulating member 30, preventing the insulating member 30 from loosening and falling off and enhancing the stability of the insulating member 30.

[0107] In some embodiments, please refer to Figure 4 andFigure 5 The clamping member 20 includes a power connection portion 24 for connecting to a power supply circuit. Exemplarily, the power connection portion 24 is connected to the clamping plate 21. The power connection portion 24 conducts electrical energy through the clamping plate 21 to the electrode plate 11. That is, the electrical energy of the power supply circuit is conducted to the electrode plate 11 through the clamping member 20, and the electrode plate 11 is electrically connected to the external power supply circuit through the clamping member 20. The power connection portions 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.

[0108] In one embodiment, please refer to Figure 4 The power connection portion 24 is connected to the periphery of the clamping plate 21. Exemplarily, the power connection portion 24 is connected to the periphery of the frame 211. In this way, the power connection portion 24 does not block the liquid passing notch 21a, and the water liquid can smoothly flow through the liquid passing notch 21a and contact the electrode assembly 10, thereby improving the electrolysis efficiency of the electrolysis device 100.

[0109] In addition, the power connection portion 24 is spaced from the fixing ear 23, which can also reduce the probability of the external wire touching other parts and reduce potential safety hazards.

[0110] In one embodiment, please continue to refer to Figure 4 Taking the plane perpendicular to the first direction as the projection plane, the projections of the power connection portions 24 of the two clamping members 20 do not overlap. That is, the projections of the two power connection portions 24 are spaced apart. In this way, the two power connection portions 24 are far apart from each other, avoiding contact short circuit between the two power connection portions 24 caused by water liquid impact or other acting forces.

[0111] In some embodiments, the electrode plate 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 plate 11 through the clamping member 20 to energize the electrode plate 11. In this way, on the one hand, there is a large contact area between the electrode plate 11 and the clamping member 20, which can reduce power loss and improve the conductive efficiency. On the other hand, it can also reduce the additional components required for energizing the electrode plate 11 and reduce the production cost.

[0112] The clamping member 20 includes but is not limited to being made of metal, having a low resistance and good electrical conductivity.

[0113] In some embodiments, please refer to Figures 7 to 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 circulation chamber 40c. Both the liquid inlet 40a and the liquid outlet 40b communicate with the circulation chamber 40c. At least a part of the electrode assembly 10 is located within the circulation chamber 40c. The aqueous liquid enters the circulation chamber 40c from the liquid inlet 40a. The electrode assembly 10 electrolyzes the aqueous liquid flowing through the circulation chamber 40c, and the electrolyzed aqueous liquid flows out from the liquid outlet 40b. The liquid inlet 40a is convenient for connecting to a water source. For example, the liquid inlet 40a and the water valve of the laundry treatment device can be connected through a pipeline or other structural components. The liquid outlet 40b is convenient for connecting to the laundry treatment chamber. For example, the liquid outlet 40b and the laundry treatment chamber can be connected through a pipeline or other structural components. The housing 40 not only helps the aqueous liquid to flow through the electrode assembly 10 concentratedly, thereby improving the electrolysis efficiency, but also can protect the electrode assembly 10.

[0114] In some embodiments, please refer to Figure 7 and Figure 8 , the liquid inlet 40a is formed on one side surface of the housing 40 along the second direction, and the liquid outlet 40b is formed on the lower surface of the housing 40. The second direction, the up-down direction, and the first direction are perpendicular to each other.

[0115] Exemplarily, the aqueous liquid enters the circulation chamber 40c substantially along the second direction, and the electrolyzed aqueous liquid is discharged from the circulation chamber 40c substantially along the up-down direction. In this way, on the one hand, the impact force of the aqueous liquid can be reduced, preventing the electrode assembly 10 from being damaged due to the excessive flow rate and / or flow volume of the aqueous liquid. On the other hand, the flow direction of the aqueous liquid entering and leaving the circulation chamber 40c changes, which can slow down the flow rate of the aqueous liquid in the circulation chamber 40c, thereby prolonging the residence time of the aqueous liquid in the circulation chamber 40c, so that the electrode assembly 10 can fully electrolyze the aqueous liquid. On the other hand, the liquid outlet 40b is formed on the lower surface of the housing 40, which can prevent water from accumulating in the circulation chamber 40c.

[0116] It should be noted that the "down" refers to the direction towards the ground, and the "up" is the opposite direction to the "down". The first direction, the second direction, and the up-down direction together constitute a three-dimensional perpendicular coordinate system.

[0117] In some embodiments, please refer to Figure 9 , the housing 40 includes a housing body 41 and a housing cover 42. The housing cover 42 covers the upper part of the housing body 41 to jointly define the circulation chamber 40c. Exemplarily, both the liquid inlet 40a and the liquid outlet 40b can be formed on the housing body 41.

[0118] In some embodiments, please refer to Figure 9, the housing 41 has an upward opening 40c1, and the housing cover 42 is covered above the housing 41 to shield the opening 40c1. In this way, on the one hand, the housing cover 42 can prevent external impurities from entering the flow chamber 40c, playing a role in protecting the electrode assembly 10; the housing cover 42 shielding the opening 40c1 can also prevent the water liquid from overflowing. On the other hand, the electrode assembly 10 can enter and exit the housing 41 through the opening 40c1, facilitating the loading, unloading and maintenance of the electrode assembly 10.

[0119] The housing 41 and the housing cover 42 can be detachably connected or non-detachably connected. Exemplarily, the housing 41 and the housing cover 42 can be welded, screwed, snapped, etc.

[0120] The number of the electrode plates 11 is at least two. That is to say, the number of the electrode plates 11 is two or more than two.

[0121] In some embodiments, the electrode assembly 10 includes two electrode plates 11, one electrode plate 11 is the cathode 111, and one electrode plate 11 is the anode 112. In some embodiments, the electrode assembly 10 includes more than two electrode plates 11. The cathode 111 and the anode 112 are a set of electrolysis groups, and a solid electrolyte 121 can be arranged between the cathode 111 and the anode 112 of each set of electrolysis groups. There can be one set or multiple sets of electrolysis groups. Exemplarily, multiple sets of electrolysis groups can be stacked along the first direction. Another example is that multiple sets of electrolysis groups can be tiled in a plane perpendicular to the first direction.
