[0032] The following further describes in detail the implementation manners of the present application with reference to the 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.

[0033] In the various specific technical features and each embodiment described in the detailed implementation manners, they can be combined in any suitable manner without contradiction. 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 construed as indicating or implying relative importance. The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] The embodiment of the present application provides a clothing treatment device, including a clothing treatment cavity and the electrolysis device 100 in any one of the embodiments of the present application. The fluid after electrolysis of the electrode assembly 10 of the electrolysis device 100 enters the clothing treatment cavity.

[0035] The clothing treatment cavity can be used to hold clothes.

[0036] In the clothing treatment device provided by the embodiment of the present application, substances such as hydroxyl radicals and / or ozone are generated after the aqueous solution is electrolyzed by the electrolysis device 100. The electrolyzed aqueous solution enters the clothing treatment cavity. Substances with strong oxidation activity such as hydroxyl radicals and / or ozone play a role in sterilizing and disinfecting clothes and preventing color bleeding. Hydrogen microbubbles can assist the detergent to remove dirt such as sebum, grease, and fine dust accumulated inside the clothing fibers, and can improve the washing ratio.

[0037] 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 disposed on the first liquid path to electrolyze the water flowing into the laundry treatment chamber.

[0038] The water source can be a tap water source or the circulating water of the laundry treatment device. That is to say, the water can be tap water. Tap water does not contain impurities such as lint and hair of clothes, 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.

[0039] 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 clothes.

[0040] The laundry treatment device can be a washing machine or a washing and drying integrated machine, etc. A washing and drying integrated machine is a laundry treatment device that integrates the washing function and the drying function.

[0041] The laundry treatment device can include a cylinder assembly, and 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, and the laundry treatment device in this embodiment is also called a pulsator-type laundry treatment device.

[0042] 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 clothes. The user puts clothes into or takes clothes out of the inner cylinder through the loading and unloading opening from the front. The inner cylinder can rotate. For example, clothes, water, detergent, etc. rotate with the inner cylinder. In this way, the clothes continuously change their postures in the inner cylinder, and fluids such as water and detergent change their flow directions with the inner cylinder.

[0043] In some embodiments, the inner cylinder can be generally in the shape of a hollow cylinder.

[0044] In some embodiments, the cylinder assembly includes an outer tub, and the inner cylinder can be disposed in the outer tub. The outer tub can be used to hold water, and the inner cylinder is used to hold clothes. In this embodiment, by holding water in the outer tub, the inner cylinder can also be called a perforated inner cylinder. Fluids can flow between the space between the outer tub and the inner cylinder and the space inside the inner cylinder through the through holes of the inner cylinder.

[0045] In some embodiments, the outer tub can be generally in the shape of a hollow cylinder.

[0046] In some embodiments, the inner cylinder holds water by itself and can also be called a non-perforated inner cylinder. An outer tub can be provided outside the non-perforated inner cylinder, or an outer tub can not be provided.

[0047] It can be understood that in some embodiments, the cylinder assembly may only have an inner cylinder and no outer barrel as described above. In this embodiment, the inner cylinder is a non-porous inner cylinder and can hold water by itself. The inner cylinder can be of a single-cylinder structure. That is to say, the laundry treatment device has only one cylinder, namely the inner cylinder.

[0048] In some embodiments, the laundry treatment device includes a cabinet, the cylinder assembly is disposed inside the cabinet, and the cabinet is provided with an opening communicating with the inside of the cylinder assembly.

[0049] In some embodiments, the cabinet can be generally in a hexahedral shape, for example, a cube shape or a cuboid shape.

[0050] 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 cylinder assembly extends in the horizontal direction, and the door seal ring can be used to seal the gap between the cylinder assembly and the opening of the cabinet. The space enclosed by the door seal ring and the space inside the inner cylinder can form a laundry treatment cavity.

[0051] 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 cylinder assembly, and the axis of the door seal ring can extend in the horizontal direction.

[0052] In the related art, the electrolysis device includes an electrode plate, and the electrode plate is used for electrolyzing a fluid. In some cases, the effective area of the electrode plate is too small to meet the laundry washing standards such as the washing ratio and the anti-color bleeding requirement. In other cases, the effective area of the electrode plate is too large, the power of the electrolysis device increases, resulting in an increase in the overall machine power, and a high-power power cord needs to be matched.

[0053] Please refer to Figures 1 to 5 , the embodiment of the present application also provides an electrolysis device 100 for a laundry treatment device, including an electrode assembly 10. The electrode assembly 10 includes an electrode plate 11, and the electrode plate 11 is formed with a through hole 11a penetrating two surfaces in its thickness direction. The effective area of at least one side surface of the electrode plate 11 in the thickness direction is 2 cm 2 to 50 cm 2 .

[0054] It should be noted that in the present application, the unit "cm 2 " is square centimeter.

[0055] The electrode assembly 10 is used for electrolyzing a fluid. The fluid can be an aqueous solution. The present application takes the fluid as an aqueous solution as an example for illustration. The electrode assembly 10 can be used for electrolyzing an aqueous solution to generate substances such as hydroxyl radicals and / or ozone with strong oxidation activity.

[0056] It should be noted that the effective area refers to the remaining area obtained by subtracting the total area of the through holes 11a from the area of one side of the electrode sheet 11 in the thickness direction. The total area of the through holes 11a refers to the sum of the areas of all the through holes 11a on this side. For example, one side of the electrode sheet 11 in the thickness 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 obtained by subtracting the sum of the areas of the plurality of circles from the rectangular area.

[0057] It should be noted that in the embodiments of the present application, "a plurality of" means that the quantity includes two or more.

[0058] It has been found through experiments that when the effective area is less than 2 cm 2 , the requirements for the washing ratio and anti-color bleeding of clothes cannot be met. When the effective area is greater than 50 cm 2 , the overall power of the clothing treatment device increases, resulting in increased energy consumption. Please refer to Table 1. Table 1 is the test result table of the washing ratio, anti-color bleeding, and power using the electrolysis device 100 of the present application. Compared with the related art, the effective area of the electrode sheet 11 in the embodiments of the present application is between 2 cm 2 and 50 cm 2 . In this way, 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 requirements for the washing ratio and anti-color bleeding of clothes can be met. 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.

[0059] Table 1

[0060] <![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

[0061] 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 an anti-color bleeding greater than 1.5 can be considered qualified.

[0062] In the electrolysis device 100 provided by the embodiments of the present application, the aqueous solution can flow through the electrode sheet 11 through the through holes 11a to reduce the resistance during the flow of the aqueous solution. The effective area of the electrode sheet 11 is set between 2 cm 2Between 0 and 50 cm 2 During this range, the electrolysis efficiency of the electrolysis device 100 is relatively high, which can meet the requirements of the washing ratio and anti-color bleeding of clothes.

[0063] In the related art, the cathode and anode of the electrolysis device are arranged at intervals, that is to say, a spacing 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 that in northern regions such as Xinjiang is as high as 500; the 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 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, and 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 water scale. Therefore, the TDS difference in water quality leads to unstable electrolyzed water effects.

[0064] In some embodiments, please refer to Figure 1 and Figure 2 , the electrode assembly 10 includes a solid electrolyte 121, 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 in the thickness direction, and the solid electrolyte 121 is arranged between the cathode 111 and the anode 112.

[0065] 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 well-known in the art that can be used for electrolysis.

[0066] The principle of the electrode assembly 10 for electrolyzing water: the 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 the solid electrolyte 121 can transfer ions. During the process of the electrode assembly 10 electrolyzing water, 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 thickness 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.

[0067] Ozone can sterilize or inhibit bacteria on clothes, etc. Ozone can also oxidize and destroy the chromophore groups of dye molecules that have dissociated into water, causing the dyes to decolorize, preventing the dissociated dyes from staining light-colored clothes and causing color bleeding. Continuing the reaction will decompose the dye molecules into harmless carbon dioxide, water, and / or inorganic salts, without secondary pollution, thus playing a role in preventing color bleeding.

[0068] Hydroxyl radicals (·OH) have an extremely high oxidation potential (2.80 eV), and their oxidation ability is extremely strong. They can sterilize or inhibit bacteria on clothes, 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 dissociated dyes to decolorize them, playing a role in preventing color bleeding.

[0069] The cathode 111 will generate hydrogen microbubbles. Since the diameter of the microbubbles is very small, usually not exceeding 50 μm (micrometers), the hydrogen microbubbles can enter the interior of the clothing fibers well during the washing process. Through the effects of microbubble bursting, adsorption and floating, etc., the microbubbles circulate and scour the clothes, assisting the detergent to remove dirt such as sebum, grease, and fine dust accumulated inside the clothing fibers, and can improve the washing ratio.

[0070] It should be noted that the cathode 111 and the anode 112 being stacked in the thickness 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 thickness direction. That is to say, the anode 112, the solid electrolyte 121, and the cathode 111 are arranged parallel to each other roughly face to face. In this way, the electrode sheet 11 and the solid electrolyte 121 can be attached. Without the anode 112 and the cathode 111 contacting and short-circuiting, the distance between the two electrodes can be reduced as much as possible, reducing energy consumption and improving the electrolysis efficiency of the electrolysis device 100.

[0071] In this embodiment, 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 conduct ions and can conduct electricity without relying on the ions in the water solution, thus avoiding the influence of water quality on the power of the electrode sheet 11.

[0072] Please refer to Figure 2 , in some embodiments, the cathode 111 contacts the solid electrolyte 121. In some embodiments, the anode 112 contacts the solid electrolyte 121. In some embodiments, both the cathode 111 and the anode 112 contact the solid electrolyte 121.

[0073] 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 energy consumption.

[0074] In some embodiments, referring to Figure 1 , with the plane perpendicular to the thickness 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. 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.

[0075] In some embodiments, referring to Figure 3 and Figure 4 , the electrolysis device 100 includes two clamping members 20, and the electrode assembly 10 is clamped between the two clamping members 20. The clamping member 20 has a limiting and fixing effect on the electrode assembly 10. Exemplarily, continue to refer to Figure 3 and Figure 4 , the electrode assembly 10 can be stacked between the two clamping members 20. The assembly method is simple, which can prevent the electrode assembly 10 from loosening and falling off, thereby improving the connection stability between the electrode assembly 10 and the two clamping members 20.

[0076] In some embodiments, referring to Figure 3 , the clamping member 20 includes a clamping plate 21, and a liquid passing notch 21a is formed in the clamping plate 21. The clamping plates 21 of the two clamping members 20 are located on both sides of the electrode assembly 10 in the thickness direction. The liquid passing notch 21a is used for the flow of water liquid, and the water liquid can flow through the liquid passing notch 21a to contact the electrode sheet 11.

[0077] Exemplarily, referring to Figure 4 , for the convenience of description, the clamping plates 21 of the two clamping members 20 are respectively defined as the first clamping plate 21b and the second clamping plate 21c, and the first clamping plate 21b, the electrode assembly 10 and the second clamping plate 21c are stacked in the thickness 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.

[0078] In some embodiments, referring to Figure 3, with a plane perpendicular to the thickness 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 avoided 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.

[0079] In some embodiments, please refer to Figure 3 , the clamping member 20 includes a power connection portion 24, and the power connection portion 24 is used to connect to the power supply circuit. Exemplarily, the power connection portion 24 is connected to the clamping plate 21. The power connection portion 24 conducts electric energy to the electrode plate 11 through the clamping plate 21. That is to say, the electric 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 poles of the power supply circuit to form an electric circuit.

[0080] In some embodiments, the electrode plate 11 is in conductive contact with the clamping member 20. That is to say, 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 the power loss and improve the conduction efficiency. On the other hand, it can also reduce the additional components required for the electrode plate 11 to be energized and reduce the production cost.

[0081] The clamping member 20 includes but is not limited to being made of metal, having a low resistance and good electrical conductivity.

[0082] In some embodiments, the ratio of the total area of the through-holes 11a to the area of one side of the electrode plate 11 in the thickness direction is 10% to 30%. Exemplarily, this ratio can be 10%, 15%, 20%, 25% or 30%, etc. By setting an appropriate ratio, the number of through-holes 11a, the current-carrying area, and the effective area of the electrode plate 11 are all appropriate, meeting the cleaning requirements and power requirements, and improving the electrolysis efficiency of the electrolysis device 100.

[0083] In some embodiments, please refer to Figure 1 , the contour shape of the electrode plate 11 is an axisymmetric figure, and at least two through-holes 11a are symmetrically distributed along the axis of symmetry of the electrode plate 11. In this way, 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, so that the water liquid can flow stably and evenly, and improve the electrolysis efficiency of the electrolysis device 100.

[0084] In some embodiments, please refer to Figure 1, the electrode sheet 11 has an axisymmetric structure. That is to say, all the through holes 11a are symmetric about the axis of symmetry of the electrode sheet 11. Thus, the through holes 11a are relatively evenly distributed on the electrode sheet 11, further improving the stability and uniformity of the water liquid during the flow process, thereby enhancing the electrolysis efficiency of the electrolysis device 100.

[0085] The shape of the through hole 11a is not limited. Exemplarily, the shape of the through hole 11a can be circular, waist-shaped, oval, polygonal or irregular, etc.

[0086] In some embodiments, please refer to Figure 5 , 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 cavity 40c. The liquid inlet 40a and the liquid outlet 40b are both communicated with the circulation cavity 40c. At least part of the electrode assembly 10 is located in the circulation cavity 40c. The water liquid enters the circulation cavity 40c from the liquid inlet 40a. The electrode assembly 10 electrolyzes the water liquid flowing through the circulation cavity 40c, and the electrolyzed water 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 members. The liquid outlet 40b is convenient for connecting to the laundry treatment cavity. For example, the liquid outlet 40b and the laundry treatment cavity can be connected through a pipeline or other structural members. The housing 40 not only helps the water liquid to flow through the electrode assembly 10 concentratedly, thereby enhancing the electrolysis efficiency, but also can protect the electrode assembly 10.

[0087] In some embodiments, please refer to Figure 5 , 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 cavity 40c. Exemplarily, both the liquid inlet 40a and the liquid outlet 40b can be formed on the housing body 41.

[0088] The housing body 41 and the housing cover 42 can be detachably connected or non-detachably connected. Exemplarily, the housing body 41 and the housing cover 42 can be welded, screwed or snapped, etc. The connection part of the housing body 41 and the housing cover 42 can be sealed to prevent the water liquid in the circulation cavity 40c from leaking.

[0089] In some embodiments, please refer to Figure 4 and Figure 6 , the electrode assembly 10 includes a support skeleton 122, and a solid electrolyte 121 is arranged on the support skeleton 122. The solid electrolyte 121 covers at least one side of the support skeleton 122 in the thickness direction.

[0090] Exemplarily, in some embodiments, the solid electrolyte 121 covers one side of the support framework 122 in the thickness direction. In some other embodiments, the solid electrolyte 121 covers both sides of the support framework 122 in the thickness direction. In some other embodiments, the solid electrolyte 121 covers all the outer surfaces of the support framework 122.

[0091] In this embodiment, the solid electrolyte 121 is used for the migration of at least one of anions and cations.
