[0001] Cross Reference to Related Applications

[0002] This application is based on Chinese Patent Application No. 202410898426.7, filed on July 4, 2024, Chinese Patent Application No. 202421574848.0, filed on July 4, 2024, and Chinese Patent Application No. 202422819091.3, filed on November 18, 2024, and claims priority to the three Chinese Patent Applications, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of laundry treatment, and in particular to a laundry treating apparatus BACKGROUND

[0004] This section is intended to provide background or context to the embodiments of the application. The description herein does not constitute admission that the prior art is prior art nor does it constitute an admission of any description in this section as prior art to an application described herein and likewise, the content of this section does not constitute admission as prior art to any patent, publication, or matter disclosed herein.

[0005] The laundry treating apparatus is equipped with an electrolysis device, which electrolyzes water liquid through electrode sheets to generate hydroxyl radicals and / or ozone and the like. Hydroxyl radicals (·OH) and ozone and the like have strong oxidation ability and have good sterilization and disinfection effects.

[0006] In related technologies, the cathode and the anode of the electrolysis device are arranged at intervals, that is, a spacing must be reserved between the cathode and the anode. In the process of electrolyzing water liquid by the cathode and the anode, ion conduction in the water liquid is relied on, and water quality differs greatly in different regions, 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 the water, and the smaller the conductivity. The difference in water quality can lead to two extreme cases. The first case: the TDS of the water liquid is too low, close to pure water, and the ions in the water liquid are too low to conduct electricity, thereby causing the electrolytic water device to be unable to electrolyze. The second case: the TDS of the water liquid 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 the water quality leads to unstable electrolytic water effect. SUMMARY

[0052] In the case of no conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific embodiments should be understood as the explanation and illustration of the purpose of the present application, and should not be regarded as an improper limitation on the present application.

[0053] It should be noted that in the embodiments of the present application, down refers to the direction of the ground, and up is opposite to down; front refers to the direction facing the user, and back is opposite to front; left refers to the side of the left hand of the user in the case that the user is located in front of the laundry treatment apparatus 1000, and right is opposite to left. The up-down direction, the left-right direction and the front-back direction are perpendicular to each other. In the embodiments of the present application, the up, down, front, back, left, right, first direction and second direction are based on the orientation or position relationship shown in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0054] Referring to Fig. 1, the embodiments of the present application provide a laundry treatment apparatus 1000, which includes an electrolytic device 100, a laundry treatment cavity, a water valve and a first liquid path 230.

[0055] The laundry treatment cavity can be used to hold laundry.

[0056] The water valve can be used to connect with a water source. The water source includes, but is not limited to, a water pipe, etc. In an embodiment, the water valve can be used to connect with the water pipe, and the water valve can be a water inlet control valve of the laundry treatment apparatus 1000. That is, the water valve can be used to provide water for the washing, rinsing, etc. of the laundry treatment apparatus 1000.

[0057] The first liquid path 230 connects the water valve and the laundry treatment cavity, and the electrolysis device 100 is disposed in the first liquid path 230. The water valve can open or shut off the water from the water source to enter the first liquid path 230. The first liquid path 230 transports the water from the water valve to the laundry treatment cavity after electrolysis by the electrolysis device 100.

[0058] Referring to FIGS. 2, 5, and 6, the electrolysis device 100 includes an electrode assembly 10, the electrode assembly 10 including electrode sheets 11 and a solid-state electrolyte 12, 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 in a first direction, and the solid-state electrolyte 12 being disposed between the cathode 111 and the anode 112. The solid-state electrolyte 12 is in a solid state and has an ion transport function. Here, the cathode 111 and the anode 112 are separated by the solid-state electrolyte 12, which can prevent the cathode 111 and the anode 112 from being in contact and short-circuited. Also, the electrolysis device 100 can not rely on ion conduction in water when operating, thereby avoiding the influence of water quality on the power of the electrolysis device 100, i.e., the solid-state electrolyte 12 ensures the normal implementation of the electrolysis process.

[0059] The electrode assembly 10 can be used to electrolyze water to generate hydroxyl radicals and / or ozone, etc. having strong oxidizing activity. The hydroxyl radicals and / or ozone, etc. having strong oxidizing activity can enter the laundry treatment cavity and sterilize and disinfect the laundry.

[0060] The principle of electrolysis of water by the electrode assembly 10 is that the solid-state electrolyte 12 is disposed between the cathode 111 and the anode 112, the solid-state electrolyte 12 separates the cathode 111 and the anode 112, and the solid-state electrolyte 12 can transmit ions. In the process of electrolysis of water by the electrode assembly 10, 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 12, for example, hydrogen ions can migrate through the solid-state electrolyte 12, and the solid-state electrolyte 12 forms high-concentration cation regions and anion regions on both sides thereof in the first direction. The surface of the anode 112 generates hydroxyl radicals and / or ozone, etc. having strong oxidizing activity, and the surface of the cathode 111 generates hydrogen.

[0061] Ozone can sterilize or inhibit bacteria on clothes, and can also oxidize and destroy the color groups of dye molecules in water to decolor the dye, prevent the dye from staining light-colored clothes to cause color mixing, and continue to react to decompose the dye molecules into harmless carbon dioxide, water and / or inorganic salt without secondary pollution, thereby preventing color mixing.

[0062] Hydroxyl radicals (·OH) have a very high oxidation potential (2.80 eV) and strong oxidation ability, can sterilize or inhibit bacteria on clothes, and can also rapidly react with most organic pollutants without selectivity to oxidize the harmful substances into carbon dioxide, water or inorganic salt without secondary pollution, and can also oxidize and destroy the free dye to decolor the dye, thereby preventing color mixing.

[0063] The cathode 111 generates hydrogen microbubbles, and since the diameter of the microbubbles is usually not greater than 50 μm, the hydrogen microbubbles can enter the inside of clothes fibers well during washing, and through the effects of microbubble explosion, adsorption and floating, the microbubbles circulate to wash clothes, and assist the detergent in removing sebum, oil, small dust and other dirt accumulated in the clothes fibers, thereby improving the cleaning ratio.

[0064] The clothes treatment device 1000 provided by the embodiments of the present application has the following advantages. On the one hand, the solid-state electrolyte 12 is arranged between the anode 112 and the cathode 111 to prevent the anode 112 and the cathode 111 from being short-circuited, and the solid-state electrolyte 12 can transmit ions and can conduct electricity without relying on ions in water, thereby avoiding the influence of water quality on the power of the electrode sheet 11. On the other hand, the water valve can supply water to the electrolysis device 100, and the water can flow through the electrolysis device 100 through the first liquid path 230, so that the electrolysis device 100 has little or no contact with the washing water in the clothes treatment cavity, the impurities such as lint can be prevented from adhering to the electrode assembly 10, the risk of the electrode sheet 11 contacting the lint is reduced, and the electrolysis efficiency of the electrode sheet 11 is improved. The water is electrolyzed by the electrolysis device 100 to generate hydroxyl radicals and / or ozone and other substances, and the electrolyzed water enters the clothes treatment cavity, and the hydroxyl radicals and / or ozone and other substances with strong oxidation activity can sterilize and disinfect clothes, prevent color mixing, and hydrogen microbubbles can assist the detergent in removing sebum, oil, small dust and other dirt accumulated in the clothes fibers, thereby improving the cleaning ratio.

[0065] It can be understood that the stacking of the cathode 111 and the anode 112 along 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. 5 and 6, the cathode 111, the anode 112, and the solid electrolyte 12 are substantially in the form of a flat plate, and the anode 112, the solid electrolyte 12, and the cathode 111 are sequentially stacked along the first direction, that is, the anode 112, the solid electrolyte 12, 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, the electrolysis efficiency of the electrolysis device 100 can be improved, and the volume of the electrolysis device 100 can be reduced, so that the electrolysis device 100 is more miniaturized, thereby facilitating the installation of the electrolysis device 100 on the clothes treatment apparatus 1000.

[0066] The clothes treatment apparatus 1000 has functions other than the washing function. For example, the clothes treatment apparatus 1000 can have a drying function. The drying function can be used to dry clothes.

[0067] The clothes treatment apparatus 1000 can be a washing machine or a washer-dryer. The washer-dryer is a clothes treatment apparatus 1000 that integrates a washing function and a drying function.

[0068] The clothes treatment apparatus 1000 can include a drum assembly 200, and the axis of the drum assembly 200 can extend in a horizontal direction. The clothes treatment apparatus 1000 in this embodiment is also referred to as a drum-type clothes treatment apparatus 1000. For example, the drum-type clothes treatment apparatus 1000 can be a drum washing machine or a drum washer-dryer.

[0069] In some embodiments, the drum assembly 200 includes a rotatable inner drum 201. The inner drum 201 has a loading / unloading opening, which can face forward. The space in the inner drum 201 is at least part of a clothes treatment cavity, and the inner drum 201 can be used to place and treat clothes. A user places or takes out clothes from the inner drum 201 through the loading / unloading opening from the front. The inner drum 201 can rotate, for example, clothes, water, and detergent rotate with the inner drum 201, so that the clothes constantly change their posture in the inner drum 201, and the water and the detergent change their flow direction with the inner drum 201.

[0070] In some embodiments, the inner drum 201 can be substantially in the form of a hollow cylinder.

[0071] In some embodiments, the tub assembly 200 includes an outer tub 202, and the inner tub 201 can be disposed in the outer tub 202. The outer tub 202 can be used to hold water, and the inner tub 201 can be used to hold laundry. In this embodiment, the outer tub 202 holds water, and the inner tub 201 can also be referred to as a perforated inner tub 201. Fluid can pass through the overflow hole of the inner tub 201 between the space between the outer tub 202 and the inner tub 201 and the space inside the inner tub 201.

[0072] In some embodiments, the outer tub 202 can be substantially hollow and cylindrical.

[0073] In some embodiments, the inner tub 201 holds water by itself and can also be referred to as a non-perforated inner tub 201. The outer tub 202 can or can not be disposed on the outside of the non-perforated inner tub 201.

[0074] It can be understood that in some embodiments, the tub assembly 200 can only have the inner tub 201 and not the outer tub 202 described above. In this embodiment, the inner tub 201 is a non-perforated inner tub 201 and can hold water by itself. The inner tub 201 can be a single-tub structure. That is, the laundry treatment apparatus 1000 only has the inner tub 201 as the tub.

[0075] For example, for the scheme in which the outer tub 202 is a water holding tub, the inner cavity of the inner tub 201 can form a laundry treatment cavity, and a washing water discharge outlet 2021 can be disposed at the bottom of the outer tub 202, so that washing water can be discharged from the outer tub 202 through the washing water discharge outlet 2021 and can be returned to the laundry treatment cavity through the circulation waterway system 300. For the scheme in which the inner tub 201 is a water holding tub, the inner cavity of the inner tub 201 can form a laundry treatment cavity, and a washing water discharge outlet can be disposed at the bottom of the inner tub 201, so that washing water can be discharged from the inner tub 201 through the washing water discharge outlet and can be returned to the laundry treatment cavity through the circulation waterway system 300.

[0076] In some embodiments, the laundry treatment apparatus 1000 includes a cabinet, and the tub assembly 200 is disposed in the cabinet. The cabinet is provided with an opening that is in communication with the interior of the tub assembly 200. For example, the front door 700 of the cabinet has an opening.

[0077] In some embodiments, the cabinet can be substantially hexahedral, such as a square or rectangular cuboid.

[0078] In some embodiments, referring to FIGS. 1 and 11, the laundry treatment apparatus 1000 includes a door body 400 and a door seal 500. The door body 400 is used to selectively open or close the opening of the cabinet, and the axis of the tub assembly 200 extends in the horizontal direction. The door seal 500 can be used to seal the gap between the tub assembly 200 and the opening of the front door 700. The space surrounded by the door seal 500 and the space inside the inner tub 201 can constitute a laundry treatment cavity.

[0079] It should be noted that the extending direction of the axis of the door seal ring 500 is consistent with the extending direction of the axis of the cylinder assembly 200, and the axis of the door seal ring 500 can extend in the horizontal direction.

[0080] In an embodiment, referring to FIGS. 5-7, the at least one electrode sheet 11 contacts the solid-state electrolyte 12. In some embodiments, the cathode 111 contacts the solid-state electrolyte 12. In some embodiments, the anode 112 contacts the solid-state electrolyte 12. In some embodiments, both the cathode 111 and the anode 112 contact the solid-state electrolyte 12.

[0081] For example, the electrode sheet 11 and the solid-state electrolyte 12 are both flat plate structures, and the electrode sheet 11 can be attached to the solid-state electrolyte 12.

[0082] In this embodiment, the at least one electrode sheet 11 contacts the solid-state electrolyte 12, 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.

[0083] In an embodiment, referring to FIGS. 1 and 5, the clothes treatment apparatus 1000 includes a detergent box 600, which is disposed in the first liquid path 230 and is located downstream of the electrolysis device 100. Part of the cavity of the detergent box 600 is part of the first liquid path 230. The water liquid after electrolysis by the electrolysis device 100 can first flow through the detergent box 600 and then enter the clothes treatment cavity. By using the cavity of the detergent box 600 as part of the first liquid path 230, the cost can be reduced by saving the pipe. The detergent box 600 is located downstream of the electrolysis device 100, which can avoid the contact between the detergent and the electrode assembly 10, avoid the pollution and scaling of the electrode sheet 11 caused by the contact between the electrode assembly 10 and the detergent, and reduce the influence of the detergent in the detergent box 600 on the electrolysis device 100.

[0084] The detergent box 600 is used to deliver the detergent to the clothes treatment cavity.

[0085] 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 clothes. The softening agent is used to soften, fluff, and eliminate static electricity of clothes. The scenting agent is used to increase the scent of clothes. The cleaning agent can be a liquid laundry detergent or a granular laundry detergent, etc.

[0086] In an embodiment, the detergent box 600 is formed with a liquid flow channel, and the first liquid path 230 can flow through the liquid flow channel. That is, the liquid flow channel is part of the first liquid path 230.

[0088] In an embodiment, the laundry treatment apparatus 1000 includes the detergent box 600 and a second liquid path connecting the water valve and the laundry treatment cavity, and the detergent box 600 is disposed in the second liquid path. The water from the water valve passes through the first liquid path 230 to the electrolysis device 100, and the water from the water valve passes through the second liquid path to the detergent box 600, and the electrolytic water of the electrolysis device 100 and the water flowing through the detergent box 600 do not affect each other. In this way, the electrolysis device 100 can be arranged flexibly, and the fluid path between the electrolysis device 100 and the laundry treatment cavity can be shortened.

[0089] In an embodiment, referring to FIG. 1, the laundry treatment apparatus 1000 includes the detergent box 600, and the electrolysis device 100 is located at the rear side of the detergent box 600. The electrolysis device 100 and the detergent box 600 are reasonably arranged, and the space in the cabinet can be fully utilized.

[0090] 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 600. If the electrolysis device 100 and the detergent box 600 are both disposed in the first liquid path 230, the distance between the electrolysis device 100 and the water valve is relatively short, and the first liquid path 230 can be conveniently routed.

[0091] In an embodiment, the laundry treatment apparatus 1000 includes the drum assembly 200, and the electrolysis device 100 is located above the drum assembly 200. The electrolysis device 100 is placed in the space above the drum assembly 200. The space in the drum assembly 200 is part of the laundry treatment cavity.

[0092] In an embodiment, referring to FIGS. 2 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 flow-through cavity 40c, the liquid inlet 40a and the liquid outlet 40b both communicate with the flow-through cavity 40c, at least part of the electrode assembly 10 is located in the flow-through cavity 40c, and the fluid of the first liquid path 230 sequentially flows through the liquid inlet 40a, the flow-through cavity 40c, and the liquid outlet 40b. For example, the water from the water valve enters the flow-through cavity 40c from the liquid inlet 40a, the electrode assembly 10 electrolyzes the water flowing 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 housing 40 not only helps the water to flow through the electrode assembly 10, thereby improving the electrolysis efficiency, but also protects the electrode assembly 10.

[0093] In an embodiment, the laundry treatment apparatus 1000 includes a dispenser drawer having a detergent dispensing cavity, and the dispenser drawer is pullably disposed in the detergent drawer 600. For example, the dispenser drawer is pullably disposed in the accommodation cavity. The detergent dispensing cavity is used to dispense the detergent.

[0095] In an embodiment, the liquid flow channel can be located above the mixing cavity, and the liquid flow channel and the mixing cavity are independent of each other. That is, the electrolyzed water in the liquid flow channel does not enter the mixing cavity, and the detergent mixture solution in the mixing cavity does not enter the liquid flow channel.

[0096] In an embodiment, the first liquid path 230 includes a first pipe that connects the water valve and the liquid inlet 40a. The water from the water valve enters the flow cavity 40c through the first pipe and the liquid inlet 40a. The first pipe is part of the first liquid path 230.

[0097] In an embodiment, referring to FIGS. 1 to 4, the first liquid path 230 includes a second pipe 210 that connects the liquid outlet 40b and the inlet of the liquid flow channel, and a third pipe 220 that connects the outlet of the liquid flow channel and the laundry treatment cavity. The electrolyzed water in the flow cavity 40c enters the laundry treatment cavity in sequence through the second pipe 210, the liquid flow channel, and the third pipe 220. The first pipe, the flow cavity 40c, the second pipe 210, the liquid flow channel, and the third pipe 220 can constitute the first liquid path 230.

[0098] In an embodiment, referring to FIG. 1, 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 cavity through the space surrounded by the door seal ring 500 without the need for an intermediate pipe to guide the liquid again.

[0099] In some embodiments, a fourth pipe connects the liquid outlet 40b and the laundry treatment cavity. In this way, the first pipe, the flow cavity 40c, and the fourth pipe can constitute the first liquid path 230. The first liquid path 230 can not pass through the detergent drawer 600.

[0100] It can be understood that part of the fourth pipe can be fixed to the detergent drawer 600, for example, the fourth pipe is fixed to the detergent drawer 600 by clamping.

[0101] In one embodiment, referring to FIGS. 2-4, 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. The first direction, the second direction, and the up-down direction are perpendicular to each other.

[0102] For example, in one embodiment, referring to FIGS. 1, 2, and 6, 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 housing 40.

[0103] In this embodiment, the water from the water valve flows into the flow-through cavity 40c along the second direction through the liquid inlet 40a, and the electrolyzed water flows out of the flow-through cavity 40c through the liquid outlet 40b. In the flow-through cavity 40c, the water flows along 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. The liquid outlet 40b is formed on the lower surface of the housing 40, which facilitates the smooth discharge of the electrolyzed water from the flow-through cavity 40c.

[0104] In one embodiment, referring to FIGS. 2 and 3, the axis of the liquid outlet 40b intersects the up-down direction. The axis of the liquid outlet 40b refers to the connecting line of the center points of the flow cross section of the liquid outlet 40b. For example, when the flow cross section of the liquid outlet 40b is circular, the axis of the liquid outlet 40b is the connecting line of the center of the circle. The axis of the liquid outlet 40b intersects the up-down direction, that is, the liquid outlet 40b extends obliquely relative to the up-down direction.

[0105] In one embodiment, the liquid outlet 40b can be located on the side of the electrode sheet 11 away from the liquid inlet 40a along the second direction. In this way, the fluid from the liquid inlet 40a can flow completely through the electrode sheet 11 along the second direction, and the water can fully contact the electrode sheet 11 before flowing out of the liquid outlet 40b.

[0106] In one embodiment, the electrode assembly 10 includes a support framework, and the solid-state electrolyte 12 is disposed on the support framework. The support framework can provide support for the solid-state electrolyte 12, increase the structural strength of the solid-state electrolyte 12, and reduce the probability of the solid-state electrolyte 12 being deformed by wrinkling.

[0107] In one embodiment, the support framework is located between the cathode 111 and the anode 112, and the solid-state electrolyte 12 covers at least one side of the support framework along the first direction.

[0108] For example, in some embodiments, the solid-state electrolyte 12 covers one side of the support framework along the first direction. In other embodiments, the solid-state electrolyte 12 covers both sides of the support framework along the first direction. In yet other embodiments, the solid-state electrolyte 12 covers all external surfaces of the support framework.

[0109] In this embodiment, the solid-state electrolyte 12 is configured to allow at least one of anions and cations to migrate. The support skeleton is configured to enhance the mechanical strength of the solid-state electrolyte 12, so that the solid-state electrolyte 12 is less likely to be punctured, and thus the risk of internal short circuit is reduced, and the solid-state electrolyte 12 is less likely to be damaged during the assembly of the electrolytic device 100.

[0110] It can be understood that the solid-state electrolyte 12 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, and the like.

[0111] In some embodiments, the solid-state electrolyte 12 can be integrated with the support skeleton, that is, the solid-state electrolyte 12 can be adhered to the support skeleton by its own force.

[0112] In some embodiments, the solid-state electrolyte 12 can be connected to the support skeleton by a fastener.

[0113] The solid-state electrolyte 12 is not limited in the manner of being attached to the support skeleton. For example, the solid-state electrolyte 12 can be attached to the support skeleton by coating, deposition, and the like.

[0114] The solid-state electrolyte 12 is not limited in type. The solid-state electrolyte 12 can be a proton membrane configured to allow hydrogen ions to migrate, and the solid-state electrolyte 12 can also be other types of solid-state membranes. For example, the solid-state electrolyte 12 includes, but is not limited to, a solid polymer solid-state electrolyte (SPEM), and the like.

[0115] The support skeleton is not limited in structure. For example, the support skeleton can be in a mesh structure. The support skeleton in the 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.

[0116] The mesh of the mesh structure is not limited in shape. The mesh can be circular, elliptical, or polygonal, and the like.

[0117] The support skeleton is not limited in material. The support skeleton can be made of an insulating material.

[0118] In some embodiments, the cathode 111 and the anode 112 can be attached to the solid-state electrolyte 12. In this way, the spacing between the cathode 111 and the anode 112 is small enough to improve the electrolysis efficiency.

[0119] In an embodiment, referring to FIGS. 5-7 and 9, 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 12. 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 12. The size of the solid-state electrolyte 12 is greater than or equal to the size of the electrode sheet 11, which not only reduces the probability of contact between the cathode 111 and the anode 112 as much as possible, thereby improving reliability and safety, but also facilitates the rapid and efficient transfer of ions by the solid-state electrolyte 12.

[0120] In an embodiment, referring to FIGS. 5-9, the electrode sheet 11 is formed with through holes 11a that extend through both sides in the first direction. For example, the cathode 111 is formed with through holes 11a that extend through both sides in the first direction. The anode 112 is formed with through holes 11a that extend through both sides in the first direction. On the one hand, water can contact and wet the solid-state electrolyte 12 through the through holes 11a; on the other hand, ozone, hydroxyl radicals, hydrogen, and other gases generated by the electrode sheet 11 can be quickly released through the through holes 11a.

[0121] The shape of the through holes 11a is not limited, and the shape of the through holes 11a includes but is not limited to a circular shape, an elliptical shape, a kidney shape, or a polygonal shape, and the like.

[0122] In some embodiments, the through holes 11a are long strip-shaped holes, and the through holes 11a can extend into long strip-shaped holes along a direction intersecting the second direction.

[0123] In an embodiment, referring to FIGS. 3 and 5, the electrolytic 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. For example, the electrode assembly 10 is clamped between the two clamping members 20, which is simple to assemble and can prevent the electrode assembly 10 from loosening and falling off to some extent, thereby improving the stability of the connection between the electrode assembly 10 and the two clamping members 20.

[0124] In an embodiment, referring to FIGS. 5, 6, and 9, 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 in the first direction. The clamping plate 21 is formed with a liquid passage gap 21a that extends through both sides of the clamping plate 21 in the first direction. The two clamping plates 21 clamp the electrode assembly 10, and the clamping plate 21 has a plate-like structure and a large contact area with the electrode assembly 10, which can effectively clamp the electrode assembly 10 and reduce the risk of displacement of the electrode assembly 10 during assembly. The liquid passage gap 21a is used for the flow of fluid such as water, and the water can flow through the liquid passage gap 21a to contact the electrode sheet 11.

[0125] The plate-like structure can be a flat plate-like structure or a curved plate-like structure.

[0126] In some embodiments, referring to FIGS. 5, 6 and 9, 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 flow of liquid to the electrode sheet 11 and the solid electrolyte 12, and the fluid can smoothly contact the electrode assembly 10.

[0127] In some embodiments, referring to FIGS. 5, 6 and 9, the clamping plate 21 includes a frame 211 and a reinforcing rib 212. The frame 211 is arranged to form an avoiding space, and the reinforcing rib 212 is arranged in the avoiding space and connected with the frame 211. The reinforcing rib 212 divides the avoiding space 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 can be used for the flow of liquid, so that the liquid passes through the avoiding space to contact the electrode sheet 11.

[0128] 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.

[0129] For example, referring to FIGS. 5 and 6, the clamping plate 21 includes at least two intersecting reinforcing ribs 212. The two reinforcing ribs 212 divide the avoiding space into a plurality of liquid passage gaps 21a with substantially the same area. In this way, the flow rate and flow velocity of the fluid passing through each liquid passage gap 21a are substantially the same, so that the fluid can stably and uniformly flow.

[0130] It should be noted that the plurality in the embodiments of the present application refers to two or more.

[0131] In some embodiments, referring to FIGS. 5, 6 and 9, the clamping member 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 members 20. The two clamping members 20 are assembled and fixed by the fixing lugs 23 and the fastener 22, which is convenient to operate and improves the assembly efficiency.

[0132] 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 member 20.

[0133] In some embodiments, referring to FIGS. 5, 6 and 9, 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 fluid passage gaps 21a, and fluid can flow through the fluid passage gaps 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.

[0134] In an embodiment, referring to FIGS. 5, 6 and 9, the fixing ears 23 are spaced apart 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 or misaligned.

[0135] In some embodiments, 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 FIGS. 5 and 6, 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, thereby protecting the electrolysis device 100 from insulation and preventing the two clamping members 20 from being short-circuited. 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.

[0136] In some embodiments, the electrode sheets 11 are in conductive contact with the clamping members 20. That is, the clamping members 20 can conduct current, and the current is transmitted to the electrode sheets 11 through the clamping members 20, thereby realizing the electrification of the electrode sheets 11. In this way, on the one hand, the electrode sheets 11 and the clamping members 20 have a large contact area, which can reduce power loss and improve the conductivity efficiency. On the other hand, the number of additional components required for the electrification of the electrode sheets 11 can be reduced, thereby reducing the production cost.

[0137] The clamping members 20 include, but are not limited to, metal members, which have low resistance and good conductivity.

[0138] In an embodiment, referring to FIGS. 5, 6 and 9, the clamping member 20 comprises an electrical connection portion 24 connected to the clamping plate 21, and projections of the electrical connection portions 24 of the two clamping members 20 are spaced apart in a plane perpendicular to the first direction. The electrical connection portion 24 is used to connect to a power supply circuit. The electrical connection portion 24 conducts electrical energy to the electrode sheet 11 through the clamping plate 21. The power supply circuit conducts electrical energy to the electrode sheet 11 through the clamping member 20, and the electrode sheet 11 is electrically connected to the power supply circuit through the clamping member 20. The electrical connection portions 24 of the two clamping members 20 are respectively electrically connected to positive and negative poles of the power supply circuit to form an electrical loop. The projections of the electrical connection portions 24 of the two clamping members 20 are spaced apart in a plane perpendicular to the first direction, that is, the projections of the electrical connection portions 24 of the two clamping members 20 do not overlap, so that the two electrical connection portions 24 are far apart, avoiding the risk of short circuit caused by water flow impact or other forces.

[0139] In an embodiment, the clamping plate 21 and the electrical connection portion 24 are integrally formed. That is, the clamping member 20 can be integrally formed. In this way, the process of separately manufacturing the electrical connection portion 24 can be reduced, and the production efficiency can be improved.

[0140] In an embodiment, referring to FIGS. 5, 6 and 9, the electrical connection portion 24 is connected to the periphery of the clamping plate 21. In an embodiment, the electrical connection portion 24 is connected to the periphery of the frame 211, so that the electrical connection portion 24 does not block the liquid passage gap 21a, and the fluid can smoothly flow through the liquid passage gap 21a and contact the electrode assembly 10, thereby improving the electrolysis efficiency of the electrolysis device 100.

[0141] In an embodiment, referring to FIGS. 2 and 9, part of the electrical connection portion 24 extends out of the housing 40. In an embodiment, 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 also be prevented from contacting the electrical connection end to a certain extent.

[0142] It can be understood that the housing 40 has a mounting hole 40d for penetrating 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 can be improved.

[0143] In an embodiment, referring to FIGS. 5, 6 and 9, one end of the electrical connection portion 24 is connected to one side of the clamping plate 21 along the second direction, and the other end of the electrical connection portion 24 is bent upward. The projection of the electrical connection portion 24 is substantially L-shaped in a plane perpendicular to the first direction.

[0144] The material of the clamping member 20 includes but is not limited to metal, which has low resistance and good conductivity.

[0145] The cathode 111 and the anode 112 can be made of materials known in the art that can be used to electrolyze water.

[0146] The number of the electrode sheets 11 is at least two. That is, the number of the electrode sheets 11 is two or more.

[0147] 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.

[0148] In some embodiments, the electrode assembly 10 includes two or more electrode sheets 11. The cathode 111 and the anode 112 form an electrolysis group, and a solid-state electrolyte 12 can be disposed 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 a first direction. For another example, a plurality of electrolysis groups can be tiled in a plane perpendicular to the first direction.

[0150] In some embodiments, referring to FIG. 4, the housing 40 includes a housing body 41 and a housing cover 42, and the housing cover 42 covers the housing body 41 to collectively define a flow passage 40c. For example, the liquid inlet 40a and the liquid outlet 40b can be formed in the housing body 41. The mounting hole 40d can be formed in the housing cover 42.

[0151] The housing body 41 and the housing cover 42 can be detachably connected or non-detachably connected. For example, the housing body 41 and the housing cover 42 can be welded, screwed, clamped, or the like. The connection between the housing body 41 and the housing cover 42 can be sealed to prevent water leakage in the flow passage 40c.

[0152] Referring to FIGS. 10 to 13, in some embodiments, the laundry treating apparatus 1000 includes a circulating water path system 300.

[0155] It can be understood that the number of electrolysis devices 100 can be multiple, one of which is arranged in the first liquid path 230, and the other of which is arranged in the circulating waterway system 300.

[0156] In this embodiment, the electrolysis device 100 is arranged in the circulating waterway system 300, and can continuously electrolyze the washing water flowing through the circulating waterway system 300 to generate active substances such as hydroxyl radicals / ozone. The electrolyzed washing water enters the clothes treatment cavity to sterilize and disinfect the clothes and prevent color from being transferred. The hydrogen gas micro-bubbles generated in the electrolysis process can assist the detergent in removing sebum, oil, and small dust accumulated inside the fibers of the clothes, thereby improving the washing effect on the clothes.

The spray port of the spray head 303 can be in communication with the clothes treatment cavity.

[0159] Specifically, the spray port of the spray head 303 can be directed towards the laundry treatment cavity to spray the backflow and electrolyzed washing water into the laundry treatment cavity by the spray head 303, so as to achieve the sterilization and disinfection effect on the laundry. Of course, the spray port of the spray head 303 can also be directed towards the door body 400 or the door seal ring 500. Specifically, the door body 400 is arranged to be openably covered at the access opening of the inner drum 201, and the door seal ring 500 is arranged at the access opening. When the door body 400 is covered at the access opening, the door body 400 abuts against and seals with the door seal ring 500.

[0161] In addition, the circulating waterway system 300 is not limited to the mode of spraying the backflow of washing water into the laundry treatment cavity by the spray head. The washing water backflow port can also be arranged at the upper portion of the outer tub 202, so that the washing water in the circulating waterway 301 flows back to the upper portion of the outer tub 202, and enters the laundry treatment cavity of the inner drum 201 through the overflow hole on the inner drum 201, so as to achieve the purpose of guiding the washing water into the laundry treatment cavity by the circulating waterway system 300.

The electrode assembly 10 electrolyzes the washing water flowing through the flow-through cavity 40c, and the electrolyzed washing water flows out of the liquid outlet 40b. The electrode assembly 10 is exposed in the flow-through cavity 40c, and the shell 40 not only facilitates the washing water to flow through the electrode assembly 10, thereby improving the electrolysis efficiency, but also protects the electrode assembly 10.

[0166] In other embodiments, the electrolysis device 100 is built in the circulating pump 302, so as to utilize the electrolysis device 100 to electrolyze the washing water flowing through the circulating pump 302, and generate active substances such as hydroxyl radicals and ozone.

Specifically, the washing water discharged from the washing water discharge port 2021 can enter the flow-through cavity 40c through the liquid inlet 40a, and contact the electrode assembly 10 located in the flow-through cavity 40c. The electrode assembly 10 electrolyzes the washing water flowing through the flow-through cavity 40c, and the electrolyzed washing water flows out of the liquid outlet 40b. The electrode assembly 10 is exposed in the flow-through cavity 40c, and the shell 40 not only facilitates the washing water to flow through the electrode assembly 10, thereby improving the electrolysis efficiency, but also protects the electrode assembly 10.

[0170] In some embodiments, the electrode assembly 10 is partially arranged in the circulation pump 302 and exposed in the circulation pump 302, and the fluid in the circulation pump 302 is in contact with the electrode assembly 10. That is, in this embodiment, the electrolysis device 100 can not be provided with the housing 40, but the electrode assembly 10 of the electrolysis device 100 is directly arranged in the circulation pump 302, and the circulation pump 302 is used to protect the electrode assembly 10 therein. In this way, the electrode assembly 10 can be more fully in contact with the fluid in the circulation pump 302, thereby improving the electrolysis efficiency, and the structure of the electrolysis device 100 is simplified, and the electrolysis device 100 is more miniaturized, which is conducive to the installation of the electrolysis device 100 in the circulation pump 302.

[0171] It should be noted that, as shown in FIGS. 12 and 13, the circulation pump 302 can be a water pump with one inlet and two outlets. Specifically, the circulation pump 302 has a water inlet 3021 in communication with the washing water discharge outlet 2021, a circulating water outlet 3022 in communication with the clothes treatment cavity, and a drain outlet 3023 in communication with the outside. When the circulating water is needed, the washing water discharged through the washing water discharge outlet 2021 can enter the circulation pump 302 through the water inlet 3021 of the circulation pump 302 and then be pumped into the clothes treatment cavity through the circulating water outlet 3022 of the circulation pump 302. When the washing water in the clothes treatment cavity needs to be discharged to the outside, the washing water discharged through the washing water discharge outlet 2021 can enter the circulation pump 302 through the water inlet 3021 of the circulation pump 302 and then be pumped to the outside of the clothes treatment device 1000 through the drain outlet 3023 of the circulation pump 302. Specifically, the pump housing 3024 is provided with an impeller, and the outlet of the circulation pump 302 can be switched by controlling the rotation direction of the impeller. For the specific structure of the circulation pump 302, the existing circulation pump 302 can be referred to for corresponding arrangement, which will not be described here.

[0172] Of course, in specific implementation, the circulation pump 302 can also be a water pump with one inlet and one outlet, and the drainage of the clothes treatment device 1000 can be realized by using an additional water pump.

[0173] In some embodiments, as shown in FIGS. 2 to 4, the cathode 111 and the anode 112 are stacked along the first direction, 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.

[0174] For example, referring to FIGS. 2 and 3, the cathode 111 and the anode 112 are stacked along the left-right direction, and the inlet 40a can be formed on the rear side of the housing 40. In this embodiment, the washing water in the circulation water path 301 flows into the flow-through cavity 40c through the inlet 40a along the second direction, and the electrolyzed water in the flow-through cavity 40c flows out through the outlet 40b. In the flow-through cavity 40c, the washing water flows along the second direction relative to the electrode assembly 10, so that the washing water continuously flows through the electrode assembly 10 and carries away the products such as ozone, hydroxyl radicals and hydrogen gas. The outlet 40b is formed on the lower surface of the housing 40, so that the electrolyzed washing water can be smoothly discharged from the flow-through cavity 40c.

[0175] In some embodiments, at least one of the cathode 111 and the anode 112 is attached to the solid electrolyte 12. In specific implementations, the cathode 111 can be attached to the solid electrolyte 12, or the anode 112 can be attached to the solid electrolyte 12, or both the cathode 111 and the anode 112 can be attached to the solid electrolyte 12.

[0176] In some embodiments, the cathode 111 is connected with a cathode connecting portion for connecting an external power line, and the anode 112 is connected with an anode connecting portion for connecting an external power line.

[0177] In specific implementations, the positive connecting portion and the negative connecting portion can be connecting terminals for facilitating the insertion of connecting wires. In this way, the external power lines can be electrically connected to the positive connecting portion and the negative connecting portion respectively to realize the conduction of the power supply, thereby improving the convenience of electrical connection. Of course, it can be understood that in other embodiments, the external power lines can be directly connected to the positive connecting portion and the negative connecting portion respectively, as long as the electrolysis of the washing water can be realized and the actual operation is not interfered.
