[0032] An embodiment of the present application provides a clothing processing device, including a drum assembly, a water channel, an ozone generator, and an ozone catalytic unit 20.

[0033] The drum assembly includes a laundry treatment drum 10 having a laundry treatment chamber for treating laundry.

[0034] The water path is in communication with the drum assembly. That is, water in the water path can enter the drum assembly and then contact the laundry in the laundry treatment cavity, and / or water in the drum assembly can enter the water path.

[0035] In some embodiments, referring to Figure 1 and Figure 4 , the drum assembly further comprises an outer tub 30, the outer tub 30 is sleeved outside the laundry treatment drum 10, the outer tub 30 is used for containing water for laundry washing, and the laundry treatment drum 10 is used for containing laundry. In this embodiment, the laundry treatment drum 10 contains water through the outer tub 30, and the laundry treatment drum 10 can also be referred to as a perforated laundry treatment drum 10. In other embodiments, the laundry treatment drum 10 contains water by itself, which can also be referred to as a non-perforated laundry treatment drum 10, and the outer tub 30 can be arranged outside the laundry treatment drum 10 or not.

[0036] It can be understood that in some embodiments, the drum assembly can only have the laundry treatment drum 10 without the above-mentioned outer tub 30, and in this embodiment, the laundry treatment drum 10 is a non-perforated laundry treatment drum, and the laundry treatment drum 10 can contain water by itself.

[0037] The specific type of the water path is not limited.

[0038] For example, in some embodiments, the water path comprises a water inlet path, the water inlet path is used for supplying water to the drum assembly, that is, the water inlet path directly or indirectly supplies water to the laundry treatment drum 10. For example, in the embodiment with the outer tub 30, the water inlet path can directly inject water into the outer tub 30, and then enter the laundry treatment cavity through the hole on the laundry treatment drum 10, and / or the water inlet path can directly spray water into the laundry treatment drum 10.

[0039] In some embodiments, a detergent box can also be arranged on the water inlet path.

[0040] It should be noted that the water inlet path refers to the flow path of the water flow from the external water source to the laundry treatment drum 10 and / or the outer tub 30, and does not specifically refer to a specific structure.

[0041] In the embodiment with the outer tub 30, the water channel can include a circulating water channel for guiding part of the washing water in the outer tub 30 to the upper portion of the laundry treatment drum 10 and guiding from above the laundry treatment cavity, and it can be understood that a circulating pump is arranged on the circulating water channel for driving the water flow of the circulating water channel. In the related art, part of the liquid detergent, washing powder and the like that is not dissolved in the water is prone to deposit at the bottom of the outer tub 30, which affects the laundry cleaning effect on the one hand, and is still prone to foaming during the rinsing stage and remains on the washed laundry, affecting the user experience. In the embodiment, the circulating water channel can promote the dissolution of the detergent at the bottom of the outer tub 30, improve the cleaning effect, and in addition, the circulating water channel sprays from above the laundry treatment cavity to the laundry, which has a foam suppression effect.

[0042] The ozone generator is used to provide ozone to the water in the water channel and / or the drum assembly. That is, at least part of the ozone generated by the ozone generator needs to be dissolved into the water to form water-soluble ozone. The water-soluble ozone can enter the laundry treatment cavity along with the water flow in the water channel.

[0043] The ozone catalysis unit 20 at least includes an ozone catalyst 22 for the chemical reaction of ozone and water in the water.

[0044] Specifically, the ozone dissolved in the water (i.e., water-soluble ozone) generates strong oxidizing substances including hydroxyl radicals under the catalysis of the ozone catalyst 22. The hydroxyl radicals have strong oxidizing ability, strong disinfection and sterilization effect, and strong decontamination ability, and have the advantages of degradation of color-removing dyes and no secondary pollution.

[0045] However, the hydroxyl radicals have a fast annihilation speed and a short diffusion distance. In the related art, one of the technical solutions is to install the ozone catalyst in the water inlet box. The hydroxyl radicals pass through a long flow path from generation to entering the laundry treatment drum 10, and many of the hydroxyl radicals are annihilated before contacting the laundry, resulting in poor sterilization and disinfection effect and poor color-removing effect.

[0046] Therefore, in some embodiments of the present application, the ozone catalysis unit 20 is arranged in the laundry treatment drum 10. In this way, the ozone catalyst 22 can catalyze the water-soluble ozone in the laundry treatment drum 10, and the ozone catalyst 22 decomposes the ozone into oxygen and highly oxidizing hydroxyl radicals in the laundry treatment drum 10. In this way, the hydroxyl radicals are generated close to the position of the dye decolorization of the laundry, and the hydroxyl radicals are efficiently utilized during the washing process, which can quickly decompose the color-removing dyes, reduce the color mixing problem in the washing process, and improve the sterilization and disinfection effect and the decontamination effect.

[0047] It is to be noted that the ozone catalytic unit 20 does not need to use electric energy and does not need to input power, and thus the ozone catalytic unit 20 can be conveniently installed in the laundry treatment drum 10.

[0048] It is to be noted that the water-soluble ozone can diffuse for a long distance, and thus the distance between the ozone generator and the laundry treatment drum 10 is not limited, as long as it is convenient to arrange.

[0049] In some embodiments, the ozone generator can release ozone into water in the water inlet channel, or release ozone into water in the circulating water channel, or release ozone into the drum assembly, for example, release ozone into water in the interval region between the laundry treatment drum 10 and the outer tub 30, and the like, which is not limited herein.

[0050] The type of the ozone generator is not limited, for example, in some embodiments, the ozone generator is used to generate ozone gas, and the ozone gas is pumped into water by a power source such as a gas pump, and then dissolved in water to obtain water-soluble ozone.

[0051] In other embodiments, the ozone generator includes a cathode and an anode, which are arranged in the water channel or the drum assembly, and are used to electrolyze water to generate ozone. In this embodiment, the ozone generator can be understood as an electrolytic electrode, which electrolyzes water by the anode and the cathode to generate strong oxidizing substances such as hydroxyl radicals, water-soluble ozone, and hydrogen peroxide. In this way, ozone gas does not need to be generated, the hazards caused by ozone gas leakage are reduced, safety is improved, and the structure is simple and convenient to install.

[0052] The installation position of the anode and the cathode is not limited, for example, it can be installed on the above-mentioned water inlet channel, it can also be installed in the interval region between the outer tub 30 and the laundry treatment drum 10, and it can also be installed on the above-mentioned circulating water channel, and the like.

[0053] Exemplarily, in some embodiments, referring to Figure 3 , the ozone catalytic unit 20 includes a shell 21, and the ozone catalyst 22 is accommodated in the shell 21. In this way, the ozone catalytic unit 20 can be pre-assembled as a whole, and then the whole is installed at a suitable position of the laundry treatment drum 10, which is convenient to install and saves assembly time.

[0054] It is to be noted that the shell 21 has a hole, so that water can pass through the hole and contact the ozone catalyst 22 inside the shell 21.

[0055] The shell 21 can be a mesh structure, can be a hard structure, can also be a woven fabric, and the like, which is not limited herein.

[0056] The form of the ozone catalyst 22 is not limited, for example, it can be in the form of a sheet, a spherical particle, or other shapes.

[0057] The type of the ozone catalyst 22 is not limited. In some embodiments, the ozone catalyst 22 includes manganese dioxide and a carrier, and the manganese dioxide is loaded on the carrier. For example, the manganese dioxide can be dispersed in the carrier in the form of manganese dioxide powder.

[0058] The carrier is advantageous to improve the dispersion and thermal stability of the manganese dioxide, and to make the ozone catalyst 22 have a suitable pore structure, shape and structural strength. In addition, the addition of the carrier can reduce the amount of the manganese dioxide component on the one hand, thereby reducing the production cost, and on the other hand, it is helpful to shape the catalyst, and is convenient to form nanoscale spherical particles.

[0059] It should be noted that the crystal form of the manganese dioxide is not limited, for example, α-MnO2, β-MnO2, γ-MnO2, ε-MnO2 and λ-MnO2, etc., which are not limited herein.

[0060] When the manganese dioxide is in contact with ozone, the manganese dioxide acts as an ozone decomposition catalyst. There are a large number of active sites on the surface of the manganese dioxide. The active sites on the surface of the manganese dioxide can effectively adsorb ozone molecules, and accelerate the breaking of ozone molecules to release oxygen and hydroxyl radicals. In addition, the manganese dioxide has low cost and long service life, and the manganese dioxide itself is also an environmentally friendly catalyst.

[0061] The type of the carrier is not limited, for example, it can include at least one of a ceramsite carrier, an aluminum-silicon carrier, and an activated carbon carrier. It should be noted that when the type of the carrier is two or more, the content of any one is not limited.

[0062] Exemplarily, the preparation method of the catalyst with the manganese dioxide loaded on the ceramsite carrier can be as follows: taking manganese nitrate as an active component precursor, mixing the manganese nitrate, ceramsite powder, polyethylene glycol and aluminum sol binder according to a certain mass ratio to form spherical particles, and then performing drying, post-treatment and other steps to obtain a manganese-based catalyst with the ceramsite carrier.

[0063] Exemplarily, the preparation method of the catalyst with the manganese dioxide loaded on the aluminum-silicon carrier can be as follows: taking manganese nitrate as an active component precursor, mixing the manganese nitrate, aluminum oxide powder, polyethylene glycol and aluminum sol binder according to a certain mass ratio to form spherical particles, and then performing drying, post-treatment and other steps to obtain a manganese-based catalyst with the aluminum oxide carrier.

[0064] Exemplarily, the preparation method of the catalyst with the manganese dioxide loaded on the activated carbon carrier can be as follows: taking manganese nitrate as an active component precursor, mixing the manganese nitrate, activated carbon powder, polyethylene glycol and aluminum sol binder according to a certain mass ratio to form spherical particles, and then performing drying, post-treatment and other steps to obtain a manganese-based catalyst with the activated carbon carrier.

[0065] Exemplarily, the manganese dioxide is doped with at least one of iron, copper and cerium. The doping of the manganese dioxide with iron, copper and cerium can significantly improve the catalytic activity and catalytic efficiency of the manganese dioxide.

[0066] The experimental data of the five specific embodiments and two comparative embodiments of the present application are briefly introduced below.

[0067] Table 1 is the absorbance experimental results of the five specific embodiments and two comparative embodiments of the present application

[0068] Serial number Experimental samples absorbance No. 1 Mixed reactive dyes 3350 No. 2 Electrode electrolysis 1457 No. 3 β single crystal manganese dioxide 1127 No. 4 δ single crystal phase manganese dioxide 970 No. 5 Fe-δ single crystal manganese dioxide 774 No. 6 Ce-δ single crystal manganese dioxide 793 No. 7 Cu-δ single crystal manganese dioxide 625

[0069] The experimental conditions are as follows: the same absorbance instrument is used to detect the absorbance of the No. 1 to No. 7 experimental samples. During the experiment, the same incident light is used to irradiate the samples (i.e. the same parameters such as light intensity and wavelength of the incident light), and the intensity of the transmitted light through the samples is detected. The intensity of the transmitted light and the incident light is compared, and the above-mentioned absorbance is obtained. The greater the value of the absorbance, the greater the degree of light absorption of the sample, and the more dye molecules in the solution; the smaller the value of the absorbance, the smaller the degree of light absorption of the sample, and the fewer dye molecules in the solution.

[0070] The No. 1 sample is a mixed reactive dye and water mixed according to a predetermined ratio, and the absorbance of the mixed solution is tested. Seven reference solutions with the same concentration can be prepared according to the ratio of the No. 1 sample.

[0071] The No. 2 sample is a solution obtained by electrolyzing the above-mentioned reference solution for a certain period of time.

[0072] The No. 3 sample is a solution obtained by catalyzing the No. 2 sample solution with a β single crystal phase manganese dioxide catalyst.

[0073] The No. 4 sample is a solution obtained by catalyzing the No. 2 sample solution with a δ single crystal phase manganese dioxide catalyst.

[0074] The No. 5 sample is a solution obtained by catalyzing the No. 2 sample solution with a Fe-δ single crystal phase manganese dioxide catalyst.

[0075] The No. 6 sample is a solution obtained by catalyzing the No. 2 sample solution with a Ce-δ single crystal phase manganese dioxide catalyst.

[0076] The No. 7 sample is a solution obtained by catalyzing the No. 2 sample solution with a Cu-δ single crystal phase manganese dioxide catalyst.

[0077] As can be seen from the table, different types of manganese dioxide catalysts can significantly reduce the absorbance of the catalyzed solution, indicating that the catalyst can effectively decompose the decolorized dye molecules, thereby reducing the problem of dyeing in the washing process.

[0078] The type of the laundry treatment apparatus is not limited, for example, it can be a pulsator type or a drum type.

[0079] The laundry treatment apparatus can be a washing machine, a washer-dryer, or the like, and is not limited herein.

[0080] Exemplarily, the laundry treatment drum 10 comprises a drum body 11. The drum body 11 is generally cylindrical, and the space inside the drum body 11 defines a laundry treatment cavity.

[0081] It should be noted that, in the process of the laundry treatment apparatus being a pulsator type laundry treatment apparatus, please refer to Figure 1 , the axis L of the drum body 11 is generally along the up-down direction, and the laundry loading / unloading opening of the laundry treatment drum 10 is located at the top side of the drum body 11. In the embodiment of the laundry treatment apparatus being a drum type laundry treatment apparatus, please refer to Figure 4 , the axis L of the drum body 11 is generally along the horizontal direction, and the laundry loading / unloading opening of the laundry treatment drum 10 is located at the front side.

[0082] Exemplarily, in some embodiments, please refer to Figure 4 and Figure 5 , the laundry treatment apparatus comprises a lifting rib 12, the lifting rib 12 is arranged on the inner side of the drum body 11, and the ozone catalysis unit 20 is arranged in the lifting rib 12.

[0083] In the process of the laundry treatment drum 10 rotating along the horizontal axis, the lifting rib 12 carries the laundry to rotate together, and the laundry is lifted to a certain height and then falls again under the action of its own gravity, thereby achieving the effect of shaking the laundry.

[0084] In this embodiment, please refer to Figure 4 and Figure 5 , arranging the ozone catalysis unit 20 in the lifting rib 12 can make full use of the space in the lifting rib 12, and it is convenient to carry the ozone catalysis unit 20 on the existing product, only a small amount of changes or no changes are made to the product structure, so that the product can be updated and iterated with less cost, which is convenient for promotion and installation.

[0085] It should be noted that, the ozone catalysis unit 20 can be arranged in each lifting rib 12, or only in part of the lifting ribs 12.

[0086] It should be noted that the lifting rib 12 has space inside itself, so the ozone catalytic unit 20 may have a shell 21 ; or it may not have a shell 21 and directly place the ozone catalyst 22 into the lifting rib 12 to accommodate the ozone catalyst 22 through the lifting rib 12 .

[0087] In other embodiments, please refer to Figure 1 and Figure 2 The laundry treatment drum 10 includes a pulsator assembly 13, and the ozone catalytic unit 20 is disposed on the pulsator assembly 13. The pulsator assembly 13 is disposed in the drum body 11 and can rotate relative to the drum body 11. In this embodiment, the structure of the pulsator assembly can be fully utilized to install the ozone catalytic unit 20.

[0088] For example, the impeller assembly includes a wheel disc, which is located at the bottom of the cylinder body 11. The upper surface of the wheel disc has multiple water-discharging ridges, which ripple the water flow. The ozone catalytic unit 20 can be installed on the wheel disc, specifically on the water-discharging ridges, or at the center of the wheel disc.

[0089] In some embodiments, the impeller assembly further comprises a stirring rod, the bottom end of which is connected to the center of the wheel disc. The ozone catalytic unit 20 may also be installed in the stirring rod.

[0090] For example, see Figure 2 The central area of ​​the impeller assembly 13 is provided with a groove 13a, see Figure 3 The ozone catalytic unit 20 includes a housing 21, with an ozone catalyst 22 housed within the housing. At least a portion of the housing 21 is inserted into the recess 13a. In other words, in this embodiment, the pulsator assembly lacks a stirring rod. This allows the ozone catalytic unit 20 to be placed closer to the clothing, further enhancing the catalytic effect.

[0091] In some embodiments, the housing 21 is detachably connected to the impeller assembly 13 , for example, by elastic hooks, etc., to facilitate installation and removal of the ozone catalytic unit 20 .

[0092] For example, in some embodiments, the laundry treatment drum 10 further includes a filter bag, and the ozone catalytic unit 20 is disposed in the filter bag.

[0093] For example, see Figure 1 The clothing processing drum 10 includes a waterfall plate 14 arranged on the inner side of the drum body 11. The waterfall plate 14 extends along the height direction of the drum body 11 and is provided with a waterfall outlet 10b. A water spray channel 10a connected to the waterfall outlet 10b is formed between the waterfall plate 14 and the inner surface of the drum body 11.

[0094] During the washing process, the water under the pulsator assembly 13 is agitated by the water-repellent structure on the bottom side of the pulsator assembly 13. The water rises along the water channel 10a under the action of centrifugal force and is sprayed from the water spout 10b. The water spout from the water spout 10b is sprayed on the clothes in the clothes treatment cavity, which can quickly wet the clothes floating on the water surface and effectively wash the residual floating foam, thereby improving the washing effect.

[0095] Exemplarily, the ozone catalysis unit 20 is arranged in the water channel 10a or on the side of the water spout plate 14 facing the axis L of the barrel body. In this embodiment, the water flow contacts the ozone catalyst 22 when flowing through the water channel 10a. In this embodiment, the water spout plate 14 provides mounting support and mounting space for the ozone catalysis unit 20.

[0096] Exemplarily, the clothes treatment barrel includes a barrel body 11, a mounting structure arranged on the inner side of the barrel body 11, and a filter bag connected to the mounting structure. The mounting structure provides mounting support for the filter bag. During the washing process, part of the water flow flows through the filter bag, and the impurities mixed in the water are intercepted by the filter bag, which is beneficial to improve the clothes cleaning effect.

[0097] In some embodiments, the ozone catalysis units are all connected to the mounting structure. That is, the mounting structure is used to mount both the filter bag and the ozone catalysis units, which can make full use of the mounting structure.
