Description

Technical Field

[0001] This invention relates to the field of water electrolysis technology, and more particularly to an electrolysis device and clothing treatment equipment. Background Technology

[0002] Currently, the water electrolysis technology in washing machines mainly utilizes flat-plate electrodes to generate hydroxyl radicals (·OH), ozone (O3), hydrogen peroxide (H2O2), and hypochlorite ions (ClO2). - It contains active substances such as ) to remove stains from clothing fibers.

[0003] Traditional flat plate electrodes have coatings on both sides of the anode, but only the coating on the side opposite the cathode can generate active substances through electrocatalysis. The best electrolysis efficiency can only be guaranteed when water flows through the electrode in a direction perpendicular or nearly perpendicular to the flat plate electrode. However, the water in the washing machine drum comes from all directions, resulting in a low efficiency in generating active substances and poor cleaning ability. Summary of the Invention

An anode conductive connector is connected to one of the core and the sleeve, and a cathode conductive connector is connected to the other. At least one of the components connected to the anode conductive connector has an electrocatalytic layer. Specifically, when the anode conductive connector is connected to the core, the electrocatalytic layer is located on the core; when the anode conductive connector is connected to the sleeve, the electrocatalytic layer is located on the sleeve. Alternatively, both the core and the sleeve may have electrocatalytic layers. An anode conductive connector can be connected to the core (or the sleeve). The electrical connector can also be connected to a cathode conductive connector. With this configuration, when the anode conductive connector and the cathode conductive connector are energized respectively, water located outside the electrolysis device can pass through the sleeve from all sides in multiple directions and come into contact with the electrocatalytic layer to undergo an electrocatalytic reaction to produce active substances. The produced active substances can also pass through the sleeve from inside in multiple directions and flow out of the electrolysis device.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0036] The electrolysis device and clothing treatment equipment will be described in detail below through specific embodiments:

[0037] Reference Figures 1 to 9 As shown, some embodiments of the present invention provide an electrolysis device 1, which includes a core 11 and a sleeve 12 sleeved outside the core 11, that is, the electrolysis device 1 adopts a sleeve-shaped structure.

[0038] The sleeve 12 is a water-permeable structure, and one of the core 11 and the sleeve 12 is connected to an anode conductive connector 13, while the other is connected to a cathode conductive connector 14. At least one of the sleeves connected to the anode conductive connector 13 is provided with an electrocatalytic layer. That is, when the anode conductive connector 13 is connected to the core 11, the electrocatalytic layer is provided on the core 11, and when the anode conductive connector 13 is connected to the sleeve 12, the electrocatalytic layer is provided on the sleeve 12. Alternatively, both the core 11 and the sleeve 12 are provided with electrocatalytic layers. The core 11 (or the sleeve 12) can be connected to either the anode conductive connector 13 or the cathode conductive connector 14.

[0039] With this configuration, when the anode conductive connector 13 and the cathode conductive connector 14 are energized respectively, water located outside the electrolysis device 1 can pass through the sleeve 12 in multiple directions from all sides of the sleeve 12 and come into contact with the electrocatalytic layer to undergo an electrocatalytic reaction to produce active substances. The produced active substances can also pass through the sleeve 12 in multiple directions from inside the sleeve 12 and flow out of the electrolysis device 1.

[0040] In other words, the electrolysis device 1 adopts a sleeve-shaped structure, and water flow from multiple directions can pass through the sleeve 12, which can ensure the efficiency of active substance generation and thus improve the stain removal ability of the clothing treatment equipment.

[0041] In a specific implementation, an electrocatalytic layer can be coated on the core 11, and an anode conductive connector 13 can be connected to the core 11 to pass a positive current to the anode conductive connector 13, so that the core 11 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1. Correspondingly, a cathode conductive connector 14 can be connected to the sleeve 12 to pass a negative current to the cathode conductive connector 14, so that the sleeve 12 forms the cathode of the electrolysis device 1.

[0042] Alternatively, an electrocatalytic layer can be coated on the sleeve 12, and an anode conductive connector 13 can be connected to the sleeve 12 to pass a positive current to the anode conductive connector 13, so that the sleeve 12 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1. Correspondingly, a cathode conductive connector 14 can be connected to the core 11 to pass a negative current to the cathode conductive connector 14, so that the core 11 forms the cathode of the electrolysis device 1.

[0043] An electrocatalytic layer can also be coated on both the core 11 and the sleeve 12. One of the core 11 and the sleeve 12 is connected to one of the anode conductive connector 13 and the cathode conductive connector 14, and the other of the core 11 and the sleeve 12 is connected to the other of the anode conductive connector 13 and the cathode conductive connector 14. By changing the connection relationship between the core 11, the sleeve 12 and the anode conductive connector 13 and the cathode conductive connector 14, the anode or cathode functions of the core 11 and the sleeve 12 can be interchanged.

[0044] In practice, the sleeve 12 is provided with a water-permeable hole 121 so that the sleeve 12 is formed as a water-permeable structure.

[0045] In some embodiments, the core 11 is a hollow core. This configuration allows the hollow area inside the core 11 to form a space for water to flow in and out. This allows water to not only enter the interior of the core 11 from the outside through the sleeve 12 to achieve an electrocatalytic reaction, but also for the water to pass through the hollow area inside the core 11 to reach the sleeve 12 for electrolysis again, thereby improving the efficiency of electrocatalysis.

[0046] Specifically, both the core 11 and the sleeve 12 can be cylindrical structures. Regardless of whether the electrocatalytic layer is placed on the core 11 or the sleeve 12, it can face the water flow from multiple directions through the sleeve 12, thereby ensuring the efficiency of the electrocatalytic reaction.

[0047] Furthermore, the walls of both the core 11 and the sleeve 12 are permeable structures. In practice, permeable holes 121 can be provided on the walls of the core 11 and the sleeve 12 respectively, so that the core 11 and the sleeve 12 form a permeable structure; alternatively, the core 11 and the sleeve 12 can be made of permeable material, relying on the permeable pores inherent in the material itself to form a permeable structure.

[0048] It is understandable that the core 11 is a hollow core, and the walls of both the core 11 and the sleeve 12 are water-permeable structures. With this configuration, water can not only enter the core 11 from the outside of the electrolysis device 1 through the sleeve 12 and the walls of the core 11 to achieve an electrocatalytic reaction, but the water entering the hollow area inside the core 11 can also pass through the core 11 to reach the sleeve 12 and flow out of the outside of the electrolysis device 1 to achieve electrolysis again. That is, multiple electrolysis from the outside to the inside and from the inside to the outside is achieved, thereby effectively improving the efficiency of the electrocatalytic reaction.

[0049] In other words, when the anode conductive connector 13 and the cathode conductive connector 14 are energized respectively, water located outside the electrolysis device 1 can pass through the sleeve 12, the electrocatalytic layer and the core 11 in sequence to enter the interior of the core 11, thereby undergoing an electrocatalytic reaction and producing active substances. Water that has entered the hollow part inside the core 11 can also flow out of the electrolysis device 1 through the core 11, the electrocatalytic layer and the sleeve 12, thereby undergoing another electrocatalytic reaction and producing active substances.

[0050] It is understandable that, since the electrolysis device 1 has a sleeve-shaped structure, water located outside the electrolysis device 1 can flow through the electrocatalytic layer when it enters the core 11 from multiple directions, and water located inside the core 11 can flow out of the electrolysis device 1 from multiple directions, thereby causing an electrocatalytic reaction and producing active substances. Compared with the traditional flat plate electrode, this setting can effectively increase the number of electrolysis activations, increase the number of sites for producing active substances, and increase the concentration of active substances, thereby improving the efficiency of active substance production and thus enhancing the decontamination ability of the electrolysis device 1.

[0051] In some embodiments, the core 11 is made of a porous conductive material to transmit current from the anode conductive connector 13 or the cathode conductive connector 14, thereby catalyzing the electrocatalytic layer to undergo an electrolytic reaction to generate active substances.

[0052] In practice, the electrocatalytic layer is made of a porous, water-permeable material so that water located outside the electrolysis device 1 can pass through the electrocatalytic layer into the core 11 and flow out of the core 11 to undergo multiple electrocatalytic reactions.

[0053] Furthermore, the electrocatalytic layer can penetrate into the core 11 and cover the pore surface inside the core 11. The increased surface area of ​​the electrocatalytic layer can provide more electrocatalytic reaction sites. By increasing the number of electrolytic active sites, the reaction rate can be accelerated, and the electrocatalytic efficiency can be further improved. At the same time, the penetration of the electrocatalytic material into the pores inside the core 11 can also protect the core 11 from being easily broken down.

[0054] It should be noted that when the electrocatalytic layer is placed on the sleeve 12, the sleeve 12 is also a porous and water-permeable structure. The electrocatalytic layer can penetrate into the interior of the sleeve 12, which can also improve the electrocatalytic efficiency and generate more active substances.

[0055] In some embodiments, the electrocatalytic layer is a titanium suboxide coating, i.e., the anode coating is a titanium suboxide coating. The oxygen in titanium suboxide can exist in two forms: lattice oxygen and adsorbed oxygen, which is beneficial for the generation of active oxygen substances. The titanium suboxide coating has a honeycomb porous structure composed of macropores and mesopores, and its electrochemical active area is 300 times its geometric area, three orders of magnitude higher than the surface area of ​​the pure electrode itself, providing excellent conditions for the efficient generation of active substances to degrade stains. Furthermore, titanium suboxide material has good conductivity, electrochemical activity, and stability, with low charge transfer resistance and diffusion resistance. Simultaneously, the oxygen evolution potential of titanium suboxide material is as high as 2.1V, a characteristic that ensures high efficiency in the electrochemical oxidation process and enables low energy consumption during the reaction.

[0056] In a specific embodiment, the electrocatalytic layer can be a tin-containing titanium suboxide coating, that is, tin can be doped into the titanium suboxide coating so that the addition of tin can generate a variety of active substances through electrocatalysis. These active substances include hydroxyl radicals (·OH) and singlet oxygen radicals. 1 O2, ozone (O3), hypochlorite ions (ClO) - At least one of them.

[0057] It should be noted that various reactive substances include, but are not limited to, hydroxyl radicals (·OH) and singlet oxygen radicals. 1 O2, ozone (O3), hypochlorite ions (ClO) - One or more active substances can be used, and different active substances can remove different pollutants, thus achieving a better decontamination effect. Furthermore, because the decay periods of various active substances differ and their generation times are sequential, they can exert their effects in sequence, thereby achieving a greater degree of decontamination. This design solves the problem of traditional planar electrodes producing only one type of active substance.

[0058] In specific implementation, the titanium suboxide coating may also contain at least one of antimony and nickel, that is, the titanium suboxide coating also contains antimony, or also contains nickel, or contains both antimony and nickel, so as to improve the catalytic activity of the titanium suboxide coating by adding antimony or nickel, thereby improving the reaction efficiency of electrocatalytic reaction and increasing the concentration of active substances.

[0059] It should be noted that the titanium suboxide coating may also contain other catalytic materials. This invention does not limit this, as long as it can improve the catalytic activity of the titanium suboxide coating and thus enhance the reaction efficiency of the electrocatalytic reaction.

[0060] In some embodiments, the electrocatalytic layer is disposed on the core 11 and / or the sleeve 12. That is, the electrocatalytic layer may be disposed only on the core 11, or only on the sleeve 12, or both the core 11 and the sleeve 12 may be disposed on the electrocatalytic layer. The specific configuration can be determined according to actual needs.

[0061] In practice, the electrocatalytic layer is disposed on the outer surface of the core 11 and / or the inner surface of the sleeve 12.

[0062] Specifically, the electrocatalytic layer is coated on the outer surface of the core 11, the anode conductive connector 13 is connected to the core 11, and the cathode conductive connector 14 is connected to the sleeve 12. The electrocatalytic layer coated on the outer surface of the core 11 can be positioned opposite to the sleeve 12, which is connected to a negative current and forms a cathode, so as to generate an electrocatalytic reaction.

[0063] In other embodiments, an electrocatalytic layer is coated on the inner surface of the sleeve 12, an anode conductive connector 13 is connected to the sleeve 12, and a cathode conductive connector 14 is connected to the core 11. The electrocatalytic layer coated on the inner surface of the sleeve 12 can be positioned opposite to the core 11, which is connected to a negative current and forms a cathode, so as to generate an electrocatalytic reaction.

[0064] In other words, in specific implementation, the electrocatalytic layer can be applied only to the outer surface of the core 11 or only to the inner surface of the sleeve 12. That is, the electrocatalytic layer can be applied only to one side of the core 11 (or sleeve 12) used as the anode, which reduces the waste caused by the double-sided coating of the traditional flat plate electrode to a certain extent.

[0065] Alternatively, an electrocatalytic layer can be coated on both the outer surface of the core 11 and the inner surface of the sleeve 12. Specifically, one of the anode conductive connector 13 and the cathode conductive connector 14 is supplied with a positive current, and the other with a negative current; the positive and negative currents are interchangeable. That is, the anode conductive connector 13 can supply both positive and negative currents, and the cathode conductive connector 14 can supply both positive and negative currents.

[0066] It is understandable that both the core 11 and the sleeve 12 are coated with an electrocatalytic layer, and the two electrocatalytic layers are electrically connected to the anode conductive connector 13 and the cathode conductive connector 14, respectively.

[0067] Specifically, a positive current can be supplied to the anode conductive connector 13 and a negative current can be supplied to the cathode conductive connector 14. When the core 11 is connected to the anode conductive connector 13 and the sleeve 12 is connected to the cathode conductive connector 14, the core 11 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1, and the sleeve 12 and the electrocatalytic layer coated thereon together form the cathode of the electrolysis device 1. When the sleeve 12 is connected to the anode conductive connector 13 and the core 11 is connected to the cathode conductive connector 14, the sleeve 12 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1, and the core 11 and the electrocatalytic layer coated thereon together form the cathode of the electrolysis device 1.

[0068] Of course, a negative current can also be supplied to the anode conductive connector 13 and a positive current can be supplied to the cathode conductive connector 14. When the core 11 is connected to the anode conductive connector 13 and the sleeve 12 is connected to the cathode conductive connector 14, the core 11 and the electrocatalytic layer coated thereon together form the cathode of the electrolysis device 1, and the sleeve 12 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1. When the sleeve 12 is connected to the anode conductive connector 13 and the core 11 is connected to the cathode conductive connector 14, the sleeve 12 and the electrocatalytic layer coated thereon together form the cathode of the electrolysis device 1, and the core 11 and the electrocatalytic layer coated thereon together form the anode of the electrolysis device 1.

[0069] In practice, after a certain number of years of use, the positive and negative currents in the anode conductive connector 13 and the cathode conductive connector 14 can be interchanged to extend their service life and reduce costs.

[0070] In some embodiments, the core 11 is a porous titanium structure, and the electrocatalytic layer is coated on the surface of the core 11, specifically on the outer surface of the core 11. An anode conductive connector 13 is connected to the core 11. A positive current is passed through the anode conductive connector 13 to form an anode, that is, a porous titanium structure is used as the anode substrate, and the porous titanium structure itself has water permeability. The sleeve 12 is a metal sleeve, specifically a stainless steel sleeve. A cathode conductive connector 14 is connected to the sleeve 12. A negative current is passed through the cathode conductive connector 14 to form a cathode. Water permeable holes are provided on the sleeve 12 so that the sleeve 12 can be formed as a water permeable structure.

[0071] In other embodiments, the sleeve 12 is a porous titanium structure, and the electrocatalytic layer is coated on the surface of the sleeve 12, specifically on the inner surface of the sleeve 12. An anode conductive connector 13 is connected to the sleeve 12. A positive current is passed to the anode conductive connector 13 to form an anode, that is, a porous titanium structure is used as the anode substrate, and the porous titanium structure itself has water permeability. The core 11 is metal, specifically a stainless steel core. A cathode conductive connector 14 is connected to the core 11. A negative current is passed to the cathode conductive connector 14 to form a cathode. Water permeable holes are provided on the core 11 so that the core 11 can be formed as a water permeable structure.

[0072] Understandably, porous titanium structures have a large surface area, increasing the number of sites for producing active substances, thereby increasing the concentration of active substances. Furthermore, they are less prone to electrical breakdown when energized. Compared to using stainless steel as the anode substrate, which requires electrocatalytic layers to be coated on both sides, using porous titanium as the anode substrate only requires coating the electrocatalytic layer on one side of the core 11 (or sleeve 12) serving as the anode substrate, thus saving material costs.

[0073] Of course, the sleeve 12 and the core 11 can also be made of other materials. This invention does not limit this, as long as they can have a water-permeable effect so that electrolyzed water can pass through the sleeve 12 and the core 11 and undergo an electrocatalytic reaction.

[0074] In some embodiments, there is a gap between the outer surface of the core 11 and the inner surface of the sleeve 12, the width of which is greater than or equal to 1 mm and less than or equal to 3 mm, so as to avoid short circuits caused by contact between the core 11 and the sleeve 12, and at the same time, to avoid compressing the space of the electrocatalytic reaction and ensure the reaction efficiency.

[0075] Understandably, the gap between the outer surface of the core 11 and the inner surface of the sleeve 12 should not be too large. In order to ensure the efficiency of the electrocatalytic reaction, the area of ​​the electrocatalytic layer needs to be within a reasonable range. If the gap between the core 11 and the sleeve 12 is too large, it will result in the entire electrolysis device being too large in size, which will not only restrict the installation, but also affect the internal space of the garment processing equipment and affect the washing efficiency. Of course, there needs to be at least a 1mm gap between the core 11 and the sleeve 12 to ensure that there is enough space between the core 11 and the sleeve 12 for the electrocatalytic reaction to occur, so as to generate enough active substances and ensure that the garment processing equipment has a certain cleaning ability.

[0076] For example, the sleeve 12 is a cylindrical sleeve with an outer diameter of 30 mm and a length of 10 cm. The core 11 is a cylindrical thin-walled core with an outer diameter of 26 mm and a length of 10 cm. The core 11 is disposed inside the sleeve 12 and does not extend beyond the sleeve 12, so that the surfaces of the core 11 and the sleeve 12 can be fully utilized.

[0077] It is understood that the electrolysis device 1 of the present invention is in the shape of a cylindrical sleeve. Compared with the flat plate electrode, when water passes through the electrolysis device 1, it can cause local turbulence, accelerate the desorption and diffusion process of bubbles, avoid the performance degradation caused by bubble adsorption, reduce the interfacial resistance between the solution and the electrolysis device 1, thereby enhancing mass transfer and reducing the activation "dead zone".

[0078] In other embodiments, a proton membrane is disposed between the outer surface of the core 11 and the inner surface of the sleeve 12, and the proton membrane is attached to both the outer surface of the core 11 and the inner surface of the sleeve 12 to improve current efficiency or reduce voltage and achieve efficiency enhancement.

[0079] Understandably, the proton exchange membrane can separate the core 11 and the sleeve 12. Specifically, the electrocatalytic layer can be coated on the outer surface of the core 11, and the proton exchange membrane can separate the electrocatalytic layer from the inner surface of the sleeve 12, respectively, and be attached to both the electrocatalytic layer and the inner surface of the sleeve 12. Alternatively, the electrocatalytic layer can also be coated on the inner surface of the sleeve 12, and the proton exchange membrane can separate the electrocatalytic layer from the outer surface of the core 11, respectively, thereby ensuring that the electrocatalytic reaction can proceed normally. Specifically, the proton exchange membrane is a perfluorosulfonic acid proton exchange membrane.

[0080] In some embodiments, the electrocatalytic layer is formed as a honeycomb porous structure, which is microscopically composed of macropores and pore media. Its electrochemical active area is 300 times its geometric area, which is three orders of magnitude higher than the surface area of ​​the pure electrode itself, providing favorable conditions for the efficient generation of active substances to degrade stains.

[0081] Other embodiments of the present invention provide a garment processing device, including a tubular assembly 2 and an electrolysis device 1 as described in any of the above embodiments, the electrolysis device 1 being disposed on the tubular assembly 2.

[0082] The garment processing equipment provided in this embodiment of the invention has the beneficial effects of the electrolysis device 1 of any of the above embodiments because it includes the electrolysis device 1 of any of the above embodiments, which will not be described again here.

[0083] In some embodiments, refer to Figures 6 to 9 As shown, the cylindrical assembly 2 includes an outer cylinder 21, and the electrolysis device 1 is disposed at the bottom of the outer cylinder 21. The electrolysis device 1 and the outer cylinder 21 are fixed relative to each other, which facilitates the introduction of current into the anode conductive connector 13 and the cathode conductive connector 14.

[0084] Specifically, the drum assembly 2 also includes an inner drum, and the outer drum 21 and the inner drum are interconnected. When washing clothes, the washing water in the inner drum is directly used as electrolyzed water and passes through the inside of the electrolysis device 1 to generate various active substances, which can enter the inner drum to treat the clothes. By increasing the number of electrolytic active sites, the reaction rate can be accelerated, making the degradation more thorough.

[0085] In some embodiments, the garment treatment device includes a water inlet, through which water enters the drum assembly 2. An electrolysis device 1 may also be provided at the water inlet, through which water flows from the water inlet to the drum assembly 2 via the electrolysis device 1. When the water flows through the electrolysis device 1, an electrolytic reaction occurs and active substances are generated. The active substances generated by electrolysis enter the interior of the drum assembly 2 with the water flow. The active substances are mixed in the washing water and can degrade stains during the garment washing process to ensure the stain removal effect.

[0086] In some embodiments, the drum assembly 2 includes an outer drum and an inner drum disposed within the outer drum. The inner drum is provided with lifting ribs and / or a lint filter, and the electrolysis device 1 is disposed at the lifting ribs or the lint filter. This arrangement secures the electrolysis device 1 inside the inner drum, allowing it to contact the washing water more fully and continuously during the washing process. This enables the electrolysis device 1 to electrolyze the washing water, generating more active substances and thus improving electrolysis efficiency and washing performance.

[0087] In a practical implementation, a wireless power transmission device for powering the electrolysis device 1 can be installed on the inner cylinder. This device transmits electrical energy wirelessly, thus eliminating the need for a conductive wire connection to an external power source and preventing interference between the inner cylinder and the conductive wire during rotation. Of course, other power supply methods can also be used to power the electrolysis device 1, such as generator power supply or power storage device power supply; this application does not impose specific limitations on these methods.

[0088] Of course, it should be noted that the electrolysis device 1 can also be set in other locations, as long as it can make the electrolysis device 1 come into contact with the washing water and can transfer the various active substances generated by electrolysis into the drum assembly 2 for washing clothes.

[0089] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
