Summary of the Invention

"A plurality" means greater than or equal to two.
[0029] The present invention provides a laundry processing device, including a drum assembly 20 (see Figure 3 and Figure 4 ), waterway and electrolysis device 10.
[0030] The drum assembly 20 has a laundry processing chamber. The laundry processing chamber is used to accommodate laundry.
[0031] See also Figure 4 The drum assembly 20 at least includes an inner drum 21, and the space inside the inner drum 21 defines a clothes processing chamber.
[0032] For example, see Figure 4 In some embodiments, the barrel assembly 20 further includes an outer barrel 22, which is mounted on the outside of the inner barrel 21 and is used to hold water. In this embodiment, the inner barrel 21 holds water through the outer barrel 22, and the inner barrel 21 can also be called a perforated inner barrel. In other embodiments, the inner barrel 21 holds water by itself and can also be called a non-perforated inner barrel. The outer barrel 22 can be set outside the inner barrel 21, or it can be omitted.
[0033] It is understandable that in some embodiments, the barrel assembly 20 may only have an inner barrel without the outer barrel 22. In this embodiment, the inner barrel 21 is a non-porous inner barrel, and the inner barrel 21 itself can hold water.
[0034] The water channel is in communication with the laundry processing chamber. It should be noted that the water channel is in communication with the laundry processing chamber means that water in the water channel can enter the laundry processing chamber, and / or water in the laundry processing chamber can enter the water channel.
[0035] See also Figure 3 The electrolysis device 10 includes an anode 11 and a cathode 13, both of which are arranged on the waterway. The cathode 13 and the anode 11 are used to electrolyze the water on the waterway.
[0036] Among them, see Figure 1 The surface of the anode 11 has a boron-doped diamond coating 112. Therefore, the anode 11 can also be called a diamond thin film electrode.
[0037] The surface of the cathode 13 has a boron-doped diamond coating.
[0038] Boron-doped diamond (BDD) coating, as an electrode material, has excellent electrochemical properties, such as a wide electrochemical potential window, low background current, good physicochemical stability, and low adsorption properties.
[0039] Since the surface of the anode 11 has a boron-doped diamond coating 112 , the anode 11 has a relatively high electrode potential; the surface of the cathode 13 has a boron-doped diamond coating 112 , so the cathode 13 can also have a relatively high electrode potential, so that the electrolysis device 10 can efficiently generate reactive oxygen species (ROS).
[0040] Reactive oxygen refers to a general term for substances composed of oxygen or containing oxygen and with active properties. Reactive oxygen includes hydroxyl radicals (·OH), water-soluble ozone (O3), hydrogen peroxide (H2O2), singlet oxygen, etc. Reactive oxygen has very high activity and can effectively degrade organic matter such as dyes.
[0041] During the electrolysis process, when current passes through the electrodes, water molecules are electrolyzed into hydrogen ions and hydroxide ions. The hydrogen ions migrate toward the cathode, and the hydroxide ions migrate toward the anode. The hydroxide ions are oxidized to oxygen or reactive oxygen species on the anode surface and released from the anode surface, while the hydrogen ions are reduced to hydrogen gas or hydrogen peroxide on the cathode surface.
[0042] It should be noted that the oxygen evolution potential (OEP) represents the reaction's tendency to proceed, and can also be understood as the potential difference that must be overcome for hydroxide ions to oxidize to oxygen or reactive oxygen species. A more positive OEP indicates the easier it is for hydroxide ions to oxidize, and the easier the reaction proceeds. The hydrogen evolution potential (HEP) represents the reaction's tendency to proceed, and can also be understood as the potential difference that must be overcome for hydrogen ions to be reduced to products such as hydrogen gas or hydrogen peroxide. A more positive HEP indicates the easier it is for hydrogen ions to be reduced, and the easier the reaction proceeds.
[0043] It should be noted that, in each reaction on the anode surface, when the oxygen evolution potential is low, the reaction in which the reaction product is oxygen prevails, while the reaction in which the reaction product is active oxygen is suppressed. When the oxygen evolution potential is high, the reaction in which the reaction product is active oxygen prevails, while the reaction in which the reaction product is oxygen is suppressed. In each reaction on the cathode surface, when the hydrogen evolution potential is low, the reaction in which the reaction product is hydrogen prevails, while the reaction in which hydrogen peroxide is suppressed. When the hydrogen evolution potential is high, the reaction in which the reaction product is hydrogen peroxide prevails, while the reaction in which the reaction product is hydrogen is suppressed.
[0044] In the clothing processing device of the embodiment of the present application, since the surfaces of the anode 11 and the cathode 13 are both provided with a boron-doped diamond coating 112, the boron-doped diamond coating makes the anode 11 have a higher oxygen evolution potential, and the boron-doped diamond coating makes the cathode 13 have a higher hydrogen evolution potential. In this way, the generation of O2 by-products can be suppressed to a certain extent in each oxidation reaction of the anode, so that the anode 11 can produce more oxygen active substances such as singlet oxygen, hydroxyl radicals and water-soluble ozone, thereby increasing the generation ratio of active oxygen products. In other words, the proportion of highly oxidizing products such as water-soluble ozone increases while the proportion of hydrolysis by-product O2 decreases, thereby improving the sterilization and anti-dye cross-coloring effects of the clothing processing device. In each reaction of the cathode 13, the generation of hydrogen microbubbles is suppressed to a certain extent, the proportion of hydrogen generation is reduced, and the proportion of hydrogen peroxide generation is high. Hydrogen peroxide has strong oxidizing properties and has a sterilization and disinfection effect; in addition, it can also reduce the risk of hydrogen embrittlement caused by hydrogen bubbles to other metal materials.
[0045] The clothing processing device of the embodiment of the present application has greatly improved electrolysis efficiency and electron utilization rate compared to the comparative example of an anode with a ruthenium-iridium coating deposited on the surface of a titanium substrate. After electrolysis by the electrolysis device 10, the oxygen activity in the water is strong, which can better achieve the whitening of white clothes, oxygen bleaching and washing of colored clothes, improve the cleaning effect, reduce dye cross-contamination, etc., and can better match the use scenarios of the clothing processing device.
[0046] It should be noted that the anode 11 includes a substrate, and the boron-doped diamond coating 112 can be deposited directly or indirectly on the surface of the substrate. The substrate is the structural support body of the anode 11.
[0047] The specific material of the substrate is not limited. For example, in some embodiments, the substrate may be a titanium substrate. The titanium substrate may be made of pure titanium or may be formed by coating a titanium film on the surface of other materials.
[0048] For some examples, see Figure 1 The anode 11 includes a silicon substrate 111 , and a boron-doped diamond coating 112 is directly or indirectly deposited on a surface of the silicon substrate 111 .
[0049] In related technologies, an iridium-based oxide coating is deposited on the surface of the anode. Due to the significant difference in thermal expansion coefficient between the iridium-based oxide coating and the substrate, the iridium-based oxide coating typically exhibits a cross-sectional crack structure. During the electrocatalytic process, the electrolyte penetrates through the cracks to the interface between the substrate and the coating, accelerating electrochemical oxidation of the substrate surface. Oxidation of the substrate surface can shorten the life of the electrode and cause the electrode catalytic material to fall off or even become inactivated.
[0050] In the embodiment of the present application, the expansion coefficients of the silicon substrate 111 and the boron-doped diamond coating 112 are relatively close, which can effectively improve the cracking phenomenon of the electrode catalytic material layer in the prior art and increase the service life of the electrode.
[0051] Illustratively, the cathode 13 comprises a substrate, and a boron-doped diamond coating 112 is formed on a surface of the substrate of the cathode 13. The substrate of the cathode 13 and the substrate of the anode 11 may be the same or different. For example, in some embodiments, the substrate of the cathode 13 and the substrate of the anode 11 are different, but the coatings on the surfaces of the cathode 13 and the anode 11 are the same, namely, the boron-doped diamond coating 112. The cathode 13 and the anode 11 cannot be used interchangeably.
[0052] In other embodiments, the substrate of the cathode 13 is the same as the substrate of the anode 11, and the coating on both surfaces is the same, namely, a boron-doped diamond coating 112, so that the anode 11 and the cathode 13 can be used interchangeably. It should be noted that the shapes of the anode 11 and the cathode 13 can be the same or different.
[0053] On the one hand, during the electrolysis process, the corrosion rate of one of the electrodes may exceed the corrosion rate of the other electrode. When the degree of corrosion of one of the electrodes reaches a certain level, the positive and negative poles of the power supply can be switched, and the polarity of the two electrodes can be exchanged. At this time, the original anode 11 is switched to the cathode 13, and the original cathode 13 is switched to the anode 11. In this way, the two electrodes have approximately the same service life, which can extend the service life of the electrolysis device 10. On the other hand, scale will gradually form on the surface of the cathode 13 during the electrolysis of water. The scale is difficult to remove, especially when the water quality is poor and the scale accumulates a lot, which will seriously affect the electrolysis efficiency of the electrolysis device 10. In the embodiment of the present application, when the scale on the cathode 13 reaches a certain level, the positive and negative poles of the power supply are switched, and the polarity of the two electrodes is exchanged. The electrode that previously deposited a certain amount of scale serves as the anode 11, and the scale will gradually peel off from the anode 11, thereby achieving the effect of removing the scale. In addition, after the electrodes are exchanged, no damage will be caused to any electrode.
[0054] The following describes the degradation effect of the electrolysis device of one embodiment of the present application on dyes in combination with experimental data.
[0055] Table 1 is a comparison table of electrolysis experiments of the electrolysis device of one embodiment of the present application and the comparative example.
[0056]
[0057] The experimental conditions in Table 1 are as follows: using standard white cloth, adding different amounts of dye, electrolyzing the mixture of dye and water using different electrolysis electrodes, and then detecting the color of the cloth after electrolysis.
[0058] All the experimental samples above had the same amount of water and the same type of dye added.
[0059] Among them, samples No. 1, No. 4 and No. 7 were prepared by adding different amounts of dye to the same volume of water, soaking a standard white cloth in the mixture of dye and water without electrolyzing the mixture, and then testing the color of the cloth after drying.
[0060] For samples No. 2, No. 5, and No. 8, different amounts of dye were added to the same volume of water. A standard white cloth was then immersed in the dye-water mixture. Using the same reference electrode, the mixture was electrolyzed, and the color of the cloth was measured after drying. The reference electrode's anode was a ruthenium-iridium coating deposited on a titanium substrate, and its cathode was stainless steel.
[0061] For samples No. 3, No. 6, and No. 9, different amounts of dye were added to the same volume of water. A standard white cloth was then immersed in the dye-water mixture. Using the same electrodes from the present embodiment, the mixture with varying amounts of dye and water was electrolyzed. After drying, the cloth's color was measured. The electrodes in the present embodiment consisted of the same anode 11 and cathode 13, both of which consisted of a boron-doped diamond coating 112 deposited on the surface of a silicon substrate 111.
[0062] Add 10 ml of dye to samples 1, 2, and 3. Add 20 ml of dye to samples 4, 5, and 6. Add 40 ml of dye to samples 7, 8, and 9.
[0063] The color difference ratios in Table 1 were calculated by dividing the CMC color difference before electrolysis by the corresponding CMC color difference after electrolysis.
[0064] The specific calculation method is as follows.
[0065] The color difference ratio of sample No. 2 is: the CMC color difference of sample No. 1 divided by the CMC color difference of sample No. 2.
[0066] The color difference ratio of sample No. 3 is: the CMC color difference of sample No. 1 divided by the CMC color difference of sample No. 3.
[0067] The color difference ratio of sample No. 5 is: the CMC color difference of sample No. 4 divided by the CMC color difference of sample No. 5.
[0068] The color difference ratio of sample No. 6 is: the CMC color difference of sample No. 4 divided by the CMC color difference of sample No. 6.
[0069] The color difference ratio of sample No. 8 is: the CMC color difference of sample No. 7 divided by the CMC color difference of sample No. 8.
[0070] The color difference ratio of sample No. 9 is: the CMC color difference of sample No. 7 divided by the CMC color difference of sample No. 9.
[0071] It can be seen from the above table that the electrolysis device 10 of the embodiment of the present application can degrade dyes to a great extent and effectively reduce the color bleeding phenomenon during the laundry process.
[0072] For example, see Figure 3 The electrolysis device 10 includes a proton exchange membrane 14 disposed between the anode 11 and the cathode 13. The proton exchange membrane 14 is used to allow hydrogen ions to pass through.
[0073] The proton exchange membrane 14 is a highly conductive membrane that can be made of a polymer material. It contains a large number of proton exchange groups that can adsorb and transfer protons. When the proton exchange membrane 14 is placed in electrolyzed water, hydrogen ions are transferred from one side of the proton exchange membrane 14 to the other side.
[0074] Water is decomposed into reactive oxygen species such as hydroxyl radicals, singlet oxygen, and ozone at the anode 11, and protons (H+) enter the cathode 13 through the proton exchange membrane 14. Electrons flow out of the anode 11, through the power circuit to the cathode 13, and the power supply provides the driving force (battery voltage). On the cathode 13 side, the protons (H+), external oxygen, and electrons recombine to produce hydrogen peroxide (H2O2). The use of the proton exchange membrane 14 can increase the concentration and proportion of reactive oxygen species.
[0075] In some embodiments, the electrode potential of the anode 11 is not less than 2.4 V (volts); and / or the electrode potential of the cathode 13 is not less than 0.75 V. In this way, as much oxygen activity as possible is generated during electrolysis.
[0076] For some examples, see Figure 2 and Figure 3 The electrolysis device 10 also includes a shell 12, which has a accommodating chamber 12a, a water inlet 12b and a water outlet 12c. The accommodating chamber 12a is connected to the water inlet 12b and the water outlet 12c; the cathode 13 and the anode 11 are both arranged in the accommodating chamber 12a. In this embodiment, the electrolysis device 10 can be connected to the waterway as a pre-assembled whole. For example, one end of one of the pipes is connected to the water inlet 12b, and one end of the other pipe is connected to the water outlet 12c, and the water source is connected. In this way, overflow electrolysis can be achieved and the electrolysis efficiency can be improved. When replacement or maintenance is required, the pipe can also be removed from the shell 12 and the electrolysis device 10 can be removed as a whole, which is convenient for operation.
[0077] The specific shape of the shell 12 is not limited, as long as it can easily accommodate the anode 11 and the anode 11.
[0078] Exemplarily, the water inlet 12 b and the water outlet 12 c are disposed on opposite sides of the housing 12 , so that it is convenient to connect the pipes from opposite sides of the housing 12 .
[0079] The structure of the cathode 13 is not limited. In some embodiments, the cathode 13 may also be a structure in which a boron-doped diamond coating is deposited on the surface of a silicon substrate.
[0080] The location of the electrolysis device 10 on the clothes processing apparatus is not limited, and the electrolysis device 10 can be set at any part of the clothes processing apparatus that can come into contact with water.
[0081] For some examples, see Figure 3The water channel includes a water inlet channel 30 for supplying water to the cylinder assembly 20 , and the electrolysis device 10 is arranged on the water inlet channel 30 .
[0082] In this embodiment, the anode 11 and the cathode 13 will not come into contact with the washing water in the barrel assembly 20, which can avoid the adverse effects of detergents, lint and other debris on the electrolysis device 10, improve the working environment of the electrolysis device 10, and increase the service life of the electrolysis device 10.
[0083] The water inlet passage 30 refers to the path for water to flow from a water source into the inner tub 21 and / or outer tub 22, and does not specifically refer to a specific structure. For example, in an embodiment with an outer tub 22, the water inlet passage 30 may directly inject water into the outer tub 22, and then enter the laundry treatment chamber through holes in the laundry treatment tub. Alternatively, the water inlet passage 30 may directly spray water into the laundry treatment tub.
[0084] Among them, the water in the water inlet waterway 30 can all flow through the electrolysis device 10, or only part of it can flow through the electrolysis device 10. The external water source is divided into at least two water inlet waterways 30, one part of which is equipped with the electrolysis device 10, and the other water inlet waterways 30 are not equipped with the electrolysis device 10. In this way, the water inlet efficiency can be taken into account.
[0085] For example, a detergent dispenser box may also be provided on the water inlet channel 30. In some embodiments, the electrolysis device 10 is provided upstream of the detergent dispenser box along the water flow direction of the water inlet channel 30, that is, the water flows through the electrolysis device 10 first and then through the detergent dispenser box; in other embodiments, the electrolysis device 10 is provided downstream of the detergent dispenser box along the water flow direction of the water inlet channel 30, that is, the water flows through the detergent dispenser box first and then through the electrolysis device 10; in still other embodiments, the electrolysis device 10 is provided within the detergent dispenser box.
[0086] Exemplarily, the laundry processing apparatus includes a circulating water circuit, which is used to guide a portion of the wash water in the laundry processing chamber to the upper portion of the tub and then to the laundry processing chamber from above. The electrolysis device 10 is disposed on the circulating water circuit. It is understood that a circulating pump is provided at the inlet of the circulating water circuit, i.e., the inlet of the circulating water circuit is connected to the outlet of the circulating pump.
[0087] In the related art, some liquid detergents, washing powder, etc. that are not dissolved in water are easily deposited at the bottom of the outer barrel 22, which on the one hand affects the cleaning effect of clothes, and on the other hand, it is still easy to foam during the rinsing stage and remain on the clothes after washing, affecting the user experience.
[0088] In this embodiment of the present application, the circulating water circuit promotes the dissolution of detergent at the bottom of the outer tub 22, improving the cleaning effect. Furthermore, the circulating water circuit sprays the laundry from above the laundry processing chamber, suppressing foam. The electrolysis device 10 in the circulating water circuit electrolyzes the circulating wash water, allowing for extended electrolytic sterilization during the wash cycle without affecting the washing time.
[0089] For some examples, see Figure 4 The electrolysis device 10 is arranged in the interval area between the outer tub 22 and the inner tub 21. It is arranged on the circumferential outside of the inner tub 21, or on the side of the inner tub 21 along the axial direction and away from the clothing loading port.
[0090] The spacing area has a relatively large space, so the size of the electrolysis device 10 can be relatively large. In addition, it is also convenient to integrate the electrolysis device 10 and the heating structure of the clothes processing equipment.
[0091] In the description of this application, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine different embodiments or examples described in this application and features of different embodiments or examples without contradiction.

Persons skilled in the art will readily appreciate that various modifications and variations are possible.
