Detailed Embodiments

[0052] The preferred embodiments of the present invention will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0053] It should be noted that in the description of the present invention, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", etc. are based on the direction or positional relationship shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0054] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "connected", "connected to", "communicated with" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] First, refer to Figure 1 , the laundry treatment device of the present invention is described by taking a washing machine as an example. As Figure 1 shown, the washing machine of the first preferred embodiment includes: a cabinet 1, a laundry treatment tub 2, and a door body 3. The laundry treatment tub 2 is arranged inside the cabinet 1, and the door body 3 is arranged to be able to control the opening and closing state of the tub opening of the laundry treatment tub 2. The laundry treatment tub 2 includes an outer tub 21 and an inner tub 22. The inner tub is arranged inside the outer tub 21. A laundry receiving cavity is formed inside the inner tub 22, and a plurality of holes (not shown in the figure) are arranged on the inner tub 22. The laundry receiving cavity is used for placing laundry. The washing machine further includes an ultraviolet irradiation device 4 and an ozone generation device 5. The ozone generation device 5 is used to generate and provide ozone. The ultraviolet irradiation device 4 can emit ultraviolet rays of any one or more of the UVA band, UVB band, and UVC band. In the air, ozone (O 3 ) can generate hydroxyl radicals (·OH) under ultraviolet irradiation. The hydroxyl radicals can comprehensively sterilize and deodorize the laundry in the laundry receiving cavity, and can make the laundry have a slightly sun-like smell. An air outlet 211 is arranged on the outer tub 21. The air outlet 211 is communicated with the laundry receiving cavity. A filtering device 9 is arranged inside the air outlet 211 and can decompose the ozone in the air discharged from the laundry receiving cavity. On the premise of being able to achieve sterilization and deodorization of the laundry, the present invention can also decompose the discharged ozone, avoid ozone leakage, and thus prevent discomfort to the human body.

[0056] Further, in the present preferred embodiment, the filtering device 9 includes a filter body made of manganese dioxide nanoparticles. The filter body covers the air outlet. The filter body is a block structure matching the air outlet 211 and is provided with a plurality of filter holes. When air passes through the filter body at the air outlet 211, since the filter body is an oxide nano-catalytic material based on manganese dioxide nanoparticles, it can decompose trace amounts of active oxygen. First, an ozone molecule adsorbs to the active site on the surface of the filter body catalyst and decomposes to form a gaseous oxygen molecule and an atomic oxygen substance; the adsorbed atomic oxygen reacts with another gaseous ozone molecule to form an adsorbed peroxide and a gaseous oxygen molecule; finally, the adsorbed peroxide intermediate decomposes to form gaseous oxygen molecules that detach from the catalyst surface, decomposing the active oxygen and preventing the leakage of active oxygen.

[0057] It should be noted that the present invention does not impose any restrictions on the specific structure of the filtering device 9 and the filter body. The filtering device 9 may also include a housing and a filter body disposed inside the housing. The housing can function to enclose the filter body and is detachably disposed at the air outlet 211 for easy disassembly and assembly; the filter body may also be in the form of an integrally formed honeycomb pore block, plate, membrane, or particles, etc. The filtering device 9 may also be in the form of a honeycomb pore block, plate, membrane, or particles, etc. made of activated carbon. Those skilled in the art can set it according to the actual situation.

[0058] In another preferred embodiment, the outer tub 21 is connected to an air outlet duct. The end of the air outlet duct forms an air outlet 211. The filtering device 9 is disposed inside the air outlet 211 or at the connection between the air outlet duct and the outer tub 21.

[0059] Continue to refer to Figure 1 , in the present preferred embodiment, the laundry treatment device further includes an air inlet duct 6 and a blower 7. The air inlet duct 6 is in communication with the laundry receiving cavity. The blower 7 is arranged to drive the air outside the laundry receiving cavity to enter the laundry receiving cavity through the air inlet duct 6. Specifically, one end of the air inlet duct 6 is in communication with the laundry receiving cavity through the outer tub 21. The other end of the air inlet duct 6 is provided with an air inlet, and the air inlet is in communication with the outside of the laundry receiving cavity. The blower 7 is disposed at a position close to the air inlet. When the blower 7 is started, air enters the air inlet duct 6 from the air inlet, then enters the laundry receiving cavity through the air inlet duct 6, and finally is discharged from the air outlet 211.

[0060] The air inlet duct 6 includes a first air duct 61 and a second air duct 62 connected in sequence. The lower end of the first air duct 61 is connected to the upper end of the right side of the outer tub 21, and an air inlet is provided at the left end of the second air duct 62 to communicate with the outside of the clothing receiving cavity. Of course, this is only a preferred setting method. In another preferred embodiment, a seal 8 is provided between the outer tub 21 and the door body 3. The seal 8 is used to seal the gap between the outer tub 21 and the door body 3. A communication hole is provided on the seal 8. The first air duct 61 communicates with the clothing receiving cavity through the communication hole, or the first air duct 61 extends into the communication hole to communicate with the clothing receiving cavity. Regarding the connection method between the air inlet duct 6 and the clothing receiving cavity, those skilled in the art can set it according to the actual situation as long as the circulation path can be realized.

[0061] Further, the diameter of the first air duct 61 is smaller than that of the second air duct 62. Based on this, when the fan 7 drives air to flow from the second air duct 62 into the first air duct 61, due to the narrowing of the diameter of the pipe fitting, the cross-section of the pipe fitting decreases and the wind speed increases. When the ozone or hydroxyl radicals enter the clothing receiving cavity through the first air duct 61, they can contact the clothes at a faster speed, avoiding accumulation above the clothing receiving cavity. And the air outlet 211 is connected to the upper left end of the outer tub 21. When the air flows, it can make the air flow reach the bottom of the clothing receiving cavity and then enter the air outlet 211 from the bottom of the clothing receiving cavity upward.

[0062] In addition, a guiding surface 31 is further provided on the door body 3 of the clothing treatment device of the present invention. The guiding surface 31 slopes downward toward the direction close to the clothing receiving cavity, which can promote the flow of air.

[0063] In another preferred implementation, the clothing treatment device of the present invention may not include the fan 7 and the air inlet duct 6. An axial flow fan blade (not shown in the figure) is provided at the left end of the inner tub 22, and only one air inlet is provided on the door body 3 or the outer tub 21. The inner tub 22 is driven by a motor. When the motor rotates, the axial flow fan blade drives the air to flow.

[0064] In another preferred embodiment, control valves are provided at both the air inlet and the air outlet 211. The control valves can control the opening and closing states of the air inlet and the air outlet 211.

[0065] Preferably, the air inlet duct 6 and the laundry receiving cavity together form a reaction chamber, in which an ozone generating device 5 and an ultraviolet irradiation device 4 are sequentially arranged in the air flow direction. Specifically, in the air flow direction, the ozone generating device 5 is located upstream of the ultraviolet irradiation device 4. Considering that there may be bends in the air inlet duct 6, if the ultraviolet irradiation device 4 is in the front and the ozone generating device 5 is in the back, and they are separated on both sides of the bend, there will be a situation where the ultraviolet irradiation device 4 cannot irradiate the ozone generated by the ozone generating device 5. By arranging the ozone generating device 5 and the ultraviolet irradiation device 4 in the air flow direction in sequence, this problem can be avoided regardless of whether there are bends in the air duct.

[0066] Continue to refer to Figure 1 , both the ozone generating device 5 and the ultraviolet irradiation device 4 are arranged in the air inlet duct 6. The air inlet duct 6, the outer tub 21 and the inner tub 22 are all made of transparent materials, so that the ultraviolet irradiation device 4 can penetrate the air inlet duct 6, the outer tub 21 and the inner tub 22 with ultraviolet rays and irradiate into the laundry receiving cavity. Since the ozone generated by the ozone generating device 5 may exist in various places in the air inlet duct 6 and the laundry receiving cavity, and by setting the air inlet duct 6, the outer tub 21 and the inner tub 22 to be transparent materials, the ozone existing in the inner tub 22 can be irradiated, improving the decomposition rate of ozone, and then generating more hydroxyl radicals, promoting the effect of sterilization and odor removal. Moreover, the ultraviolet band can directly irradiate the laundry, promoting the effect of the smell of sunlight on the laundry.

[0067] As Figure 2 shown, the difference between the washing machine of the second preferred embodiment of the present invention and the first preferred embodiment lies in that the ultraviolet irradiation device 4 is arranged on the seal 8, and the other settings are the same, which will not be elaborated here.

[0068] As Figure 3 shown, the difference between the washing machine of the third preferred embodiment of the present invention and the first preferred embodiment lies in that the ultraviolet irradiation device 4 is arranged on the inner wall of the outer tub 21, and the other settings are the same, which will not be elaborated here.

[0069] In the second and third preferred embodiments, the light irradiation direction of the ultraviolet irradiation device 4 is towards the laundry receiving cavity. In this case, even if the air inlet duct 6, the outer tub 21 and the inner tub 22 are not set to be transparent materials, it can also promote the effect of the smell of sunlight on the laundry and the effect of sterilization and odor removal, as long as the ultraviolet irradiation device 4 is set to be able to irradiate the UVC band ultraviolet rays into the laundry receiving cavity. Those skilled in the art can set it according to the actual situation.

[0070] The ultraviolet irradiation device 4 can be installed by means of snap connection, bolt connection or bonding.

[0071] Further, the ozone generating device 5 of the present invention includes an ozone generating member 51 and a driving power source 52 connected to each other. The driving power source 52 is a high-voltage driving power source, a high-voltage power supply board, or a high-voltage coil driving device. The ozone generating member 51 is an ozone generating sheet or an ozone generating needle. When the driving power source 52 is energized, ozone can be generated at the ozone generating member 51, that is, oxygen is converted into O 3 , in the present invention, the driving power source 52 is arranged outside the air inlet duct 6, and the ozone generating member 51 is arranged inside the air inlet duct 6. The two are electrically connected through wires. Of course, this is only a preferred arrangement. It is also possible that the entire ozone generating device 5 is arranged outside the air inlet duct 6. In this case, a communication hole is opened on the air inlet duct 6, and the ozone generating device 5 provides ozone into the air inlet duct through this communication hole, and the ozone generating device 5 is hermetically connected to the communication hole. It is also possible that the entire ozone generating device 5 is arranged inside the air inlet duct 6, and those skilled in the art can set it according to the actual situation.

[0072] Those skilled in the art can understand that in other types of clothing treatment devices, the ultraviolet irradiation device 4 can also be arranged in the clothing accommodation cavity or on the door body 3, as long as the ultraviolet irradiation device 4 is arranged to be able to irradiate ultraviolet rays into the clothing accommodation cavity, and those skilled in the art can set it according to the actual situation.

[0073] In the embodiment where the ultraviolet irradiation device 4 is arranged in the second air duct 62, an ultraviolet reflector can be arranged in the first air duct 61 to reflect the ultraviolet rays into the clothing accommodation cavity.

[0074] Further, the clothing treatment device further includes a heating device (not shown in the figure). The heating device is arranged to be able to heat and decompose the ozone generated by the ozone generating device. When both the ozone generating device 5 and the ultraviolet irradiation device 4 are working, starting the heating device can promote the decomposition of ozone. When both the ozone generating device 5 and the ultraviolet irradiation device 4 are not working, starting the heating device can decompose the remaining ozone to avoid ozone leakage to the outside of the clothing treatment device, thereby avoiding harm to the human body.

[0075] It should be noted that although the present invention is described by taking a washing machine as an example only, this is not restrictive. The laundry treatment device may also be a dryer, a washer-dryer, a laundry storage cabinet, a shoe washing and care device or a garment care machine, as long as it includes a laundry receiving cavity, an air outlet 211, an ozone generating device 5, an ultraviolet irradiation device 4 and a filtering device 9; the air outlet 211 is communicated with the laundry receiving cavity; the ozone generating device 5 is arranged to be able to provide ozone into the laundry receiving cavity; the ultraviolet irradiation device 4 is arranged to be able to irradiate the ozone generated by the ozone generating device 5; the filtering device 9 is arranged in the air outlet 211 and can filter and decompose the ozone in the air discharged from the laundry receiving cavity. In other preferred embodiments, the difference between it and the washing machine lies only in the components forming the laundry receiving cavity except for the common knowledge differences in the prior art, and the rest of the setting methods are the same. For example, the setting methods and specific structures of the air inlet duct 6, the ozone generating device 5, the ultraviolet irradiation device 4 and the filtering device 9 will not be elaborated here, and those skilled in the art can set them according to the actual situation by themselves.

[0076] Those skilled in the art can understand that the ozone generating device 5 can be the device described in the present invention or other existing devices capable of generating ozone, such as an ozone generator. The change in the structure of the ozone generating device 5 does not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0077] Preferably, the ultraviolet irradiation device 4 is only capable of emitting ultraviolet rays in the UVC band, and the irradiation of ultraviolet rays in the UVC band can avoid damage or aging of clothes or components of the laundry treatment.

[0078] It should be noted that the present invention does not impose any restrictions on the specific structure of the ultraviolet irradiation device 4. The ultraviolet irradiation device 4 can be an LED lamp capable of emitting ultraviolet rays, or a low-pressure mercury lamp or a high-pressure mercury lamp, etc. The ultraviolet irradiation device 4 can emit one or any combination of ultraviolet rays in the UVA band, the UVB band or the UVC band. The ultraviolet irradiation device 4 can also be a device including an ultraviolet ray-emitting lamp and a moving member for driving the lamp to rotate or move, so as to enable the lamp to be adjusted for irradiation and make the irradiation more comprehensive. Those skilled in the art can set it according to the actual situation by themselves.

[0079] In another preferred embodiment, the laundry treatment device further includes an oxygen storage tank for providing oxygen into the laundry treatment device, which helps to generate ozone.

[0080] After the ozone generating device 5 and the ultraviolet irradiation device 4 are started, ozone, hydroxyl radicals, ultraviolet rays and the fabric undergo a photochemical reaction similar to sunlight, catalyzing the oxygenolysis of the clothing, and the smell of long-term sun-dried clothes can be achieved in a short time. The treated clothes can produce at least one natural substance among decanal, nonanal, octanal, and hexanal. The fragrance combinations that can be produced are: sweet fragrance, citrus fragrance, wax fragrance, floral fragrance; wax fragrance, citrus fragrance, fatty fragrance and floral fragrance; sweet orange, slight grease, honey-like aroma; grease, grassy smell and apple fragrance, so as to achieve the sunlight smell produced by sun-drying clothes and quilts, thereby making the user happy.

[0081] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
