[0057] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners 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.

[0058] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", etc. are based on the directions or positional relationships 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, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0059] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, 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 situations.

[0060] 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 1As shown in the figure, the washing machine of the first preferred embodiment includes: a cabinet 1, a laundry treatment tub 2, and a door 3. The laundry treatment tub 2 is disposed within the cabinet 1, and the door 3 is configured 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 22 is disposed within the outer tub 21. The tub opening on the right side of the outer tub 21 is the tub opening of the laundry treatment tub 2. A laundry receiving cavity is formed within the inner tub 22 for placing laundry. The washing machine further includes a UV-C irradiation device 4 and an ozone generation device 5. The ozone generation device 5 is used to generate and provide ozone. The UV-C irradiation device 4 is capable of emitting ultraviolet light in the UV-C band. In the air, ozone (O 3 ) can generate hydroxyl radicals (·OH) under the irradiation of ultraviolet light in the UV-C band. The hydroxyl radicals can comprehensively sterilize and deodorize the laundry within the laundry receiving cavity, and can make the laundry produce a slight smell of sunlight. At the same time, irradiation with ultraviolet light in the UV-C band will not cause aging or damage to the components of the laundry treatment device or the laundry being treated.

[0061] Furthermore, the laundry treatment device includes a duct 6 and a blower 7 disposed within the duct 6. Both ends of the duct 6 are in communication with the laundry receiving cavity. The duct 6 and the laundry receiving cavity together form a circulation path. The blower 7 is capable of driving air to flow within the circulation path. The ozone generation device 5 and the UV-C irradiation device 4 are both disposed within the circulation path. The ozone generation device 5 generates ozone, and the ozone is irradiated by ultraviolet light in the UV-C band to generate hydroxyl radicals. When the blower 7 is started, the ozone and the hydroxyl radicals enter the laundry receiving cavity to comprehensively sterilize and deodorize the laundry.

[0062] The circulation path is closed, and the air flow continuously circulates within the circulation path. This can not only improve the air fluidity, contribute to the treatment of the laundry, and make the sterilization and deodorization effect of the laundry better, but also prevent ozone from leaking to the outside of the laundry treatment device, thereby avoiding harm to the human body caused by ozone.

[0063] Preferably, both the ozone generation device 5 and the UV-C irradiation device 4 are disposed within the duct 6. The duct 6, the outer tub 21, and the inner tub 22 are all made of transparent materials, so that the UV-C irradiation device 4 can penetrate the duct 6, the outer tub 21, and the inner tub 22 with ultraviolet light in the UV-C band and irradiate into the laundry receiving cavity. Since the air within the circulation path is always in a flowing state, the ozone generated by the ozone generation device 5 may exist in various places within the circulation path. By setting the duct 6, the outer tub 21, and the inner tub 22 to be made of transparent materials, the ozone present within the inner tub 22 can be irradiated, improving the decomposition rate of ozone, and thus generating more hydroxyl radicals, promoting the sterilization and deodorization effect. Moreover, the ultraviolet light in the UV-C band can directly irradiate the laundry, promoting the effect of the smell of sunlight on the laundry.

[0064] Continue to refer toFigure 1 , as Figure 1 shown, both ends of the pipeline 6 are connected to the outer barrel 21. The pipeline 6 includes a first air duct 61, a second air duct 62, and a third air duct 63 connected in sequence. The lower end of the first air duct 61 is connected to the upper end on the right side of the outer barrel 21, and the third air duct 63 is connected to the upper part above the left end of the outer barrel 21. Of course, both ends of the pipeline 6 being connected to the outer barrel 21 is merely a preferred setting. In the second preferred embodiment, as Figure 2 shown, a seal 8 is provided between the outer barrel 21 and the door body 3. The seal 8 is used to seal the gap between the outer barrel 21 and the door body 3. A communication hole is provided on the seal 8. The first air duct 61 is connected to the clothing accommodation cavity through the communication hole, or the first air duct 61 may extend into the communication hole to be connected to the clothing accommodation cavity. Regarding the connection method between the pipeline 6 and the clothing accommodation cavity, those skilled in the art can set it according to the actual situation as long as a circulation path can be formed.

[0065] Furthermore, the diameter of the first air duct 61 is smaller than that of the second air duct 62, and the diameter of the first air duct 61 is smaller than that of the third air duct 63. 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 accommodation cavity through the first air duct 61, they can contact the clothing at a faster speed, avoiding accumulation above the clothing accommodation cavity. Moreover, the third air duct 63 is connected to the upper part above the left end of the outer barrel 21. During the air flow circulation, it can make the air flow reach the bottom of the clothing accommodation cavity and then enter the third air duct 63 from the bottom of the clothing accommodation cavity, and circulate continuously based on this.

[0066] 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 inclines downward towards the direction close to the clothing accommodation cavity, which can promote the air flow.

[0067] Preferably, the ozone generating device 5 of the present invention includes a connected ozone generating component 51 and a driving power supply 52. The driving power supply 52 is a high-voltage driving power supply, a high-voltage power board, or a high-voltage coil driving device. The ozone generating component 51 is an ozone generating sheet or an ozone generating needle. When the driving power supply 52 is powered on, ozone can be generated at the ozone generating component 51, that is, oxygen is changed into O 3 . In the present invention, the driving power supply 52 is arranged outside the pipeline 6, and the ozone generating component 51 is arranged inside the pipeline. The two are electrically connected through wires. Of course, this is merely a preferred setting. It can also be that the ozone generating device 5 is entirely arranged outside the pipeline 6, or it can be that the ozone generating device 5 is entirely arranged inside the pipeline 6. Those skilled in the art can set it according to the actual situation.

[0068] Next, refer toFigure 2 , the difference between the second preferred embodiment and the first preferred embodiment is that: the first air duct 61 is connected to the clothing receiving cavity through a seal 8, and the ultraviolet UVC irradiation device 4 is arranged on the inner wall of the outer tub 21. The remaining settings are the same and will not be elaborated here.

[0069] Next, refer to Figure 3 , the difference between the third preferred embodiment and the second preferred example is that: the ultraviolet UVC irradiation device 4 is arranged in the third air duct 63, and the remaining settings are the same and will not be elaborated here.

[0070] Next, refer to Figure 4 , the difference between the fourth preferred embodiment and the second preferred embodiment is that: the ultraviolet UVC irradiation device 4 is arranged on the seal 8, and the remaining settings are the same and will not be elaborated here.

[0071] In the second and fourth preferred embodiments, the light irradiation direction of the ultraviolet UVC irradiation device 4 is towards the clothing receiving cavity. In this case, even if the pipes 6, the outer tub 21, and the inner tub 22 are not made of transparent materials, it can still promote the sunlight smell effect of the clothes and the sterilization and odor removal effect.

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

[0073] The ultraviolet UVC irradiation device 4 can be installed by means of snap connection, bolts, or bonding.

[0074] In the embodiment where the ultraviolet UVC irradiation device 4 is arranged in the pipe 6, an ultraviolet reflector can be arranged in the pipe 6 to reflect the UVC band ultraviolet rays into the clothing receiving cavity.

[0075] Furthermore, the clothing treatment device further includes a heating device (not shown in the figure), and 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 UVC 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 UVC 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.

[0076] It should be noted that although the present invention is described only by taking a washing machine as an example, this is not restrictive. The laundry treatment device can also be a dryer, a washer-dryer, a clothes storage cabinet, a shoe washing and care device or a clothes care machine, as long as it includes a clothes receiving cavity, an ozone generating device 5 and a UV-C irradiation device 4; the ozone generating device 5 is configured to be able to supply ozone into the clothes receiving cavity; the UV-C irradiation device 4 is configured to be able to irradiate the ozone generated by the ozone generating device 5. In other preferred embodiments, the difference from the washing machine lies only in the components forming the clothes receiving cavity other than 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 pipeline 6, the ozone generating device 5 and the UV-C irradiation device 4 will not be elaborated here, and those skilled in the art can set them according to the actual situation by themselves.

[0077] 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. Changes in the structure of the ozone generating device 5 do not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0078] It should be noted that the present invention does not impose any restrictions on the specific structure of the UV-C irradiation device. The UV-C irradiation device 4 can be an LED lamp capable of emitting UV-C band ultraviolet rays, or a low-pressure mercury lamp or a high-pressure mercury lamp, etc. The UV-C irradiation device 4 can also include a UV lamp capable of emitting UV-C band ultraviolet rays and a moving member for driving the lamp to rotate or move, so as to enable the lamp to be adjusted for irradiation and the irradiation to be more comprehensive.

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

[0080] In another preferred embodiment, the laundry treatment device further includes a water mist nozzle and a water storage tank connected to each other. The water mist nozzle is used to supply a small amount of water molecules into the clothes receiving cavity to promote the generation of hydroxyl radicals.

[0081] After the ozone generating device 5 and the UV-C irradiation device 4 are started, ozone, hydroxyl radicals, UV-C band ultraviolet rays and the fabric undergo a photoreaction similar to sunlight, catalyzing the clothes to undergo oxygenolysis, and the smell of drying clothes for a long time 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 and grassy aroma and apple fragrance, so as to achieve the smell of sunlight produced by drying clothes and quilts, thereby making the user happy.

Specifically, the greater the power of the ozone generating device 5, the greater the amount of ozone generated. In order to enable the generated ozone to be fully decomposed to generate more hydroxyl radicals, the power of the UV-C irradiation device 4 is controlled according to the power of the ozone generating device 5, so that the irradiation intensity of the UV-C irradiation device 4 can fully decompose the hydroxyl radicals, or the decomposed ozone accounts for a preset percentage of the total generated ozone. Those skilled in the art can set the preset percentage according to the actual situation, and preferably it is 20%-60%.

[0086] A one-to-one correspondence table of the power of the ozone generating device 5 and the power of the UV-C irradiation device 4 can be formulated, or a one-to-one correspondence table of each range of the power of the ozone generating device 5 and each range of the power of the UV-C irradiation device 4 can also be formulated, and the power of the UV-C irradiation device 4 is controlled according to the corresponding relationship in the table.

[0087] In the control method of another preferred embodiment, the power of the ozone generating device 5 is controlled according to the power of the UV-C irradiation device 4. So that under a certain irradiation intensity, the ozone generated by the ozone generating device 5 can be fully decomposed, or the decomposed ozone accounts for a preset percentage of the total generated ozone. Those skilled in the art can set the preset percentage according to the actual situation, and preferably it is 20%-60%.

[0088] A one-to-one correspondence table of the power of the ozone generating device 5 and the power of the UV-C irradiation device 4 can be formulated, or a one-to-one correspondence table of each range of the power of the ozone generating device 5 and each range of the power of the UV-C irradiation device 4 can also be formulated, and the power of the ozone generating device 5 is controlled according to the corresponding relationship in the table.
