[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] See first Figure 1 ,like Figure 1 As shown, the clothes dryer of the first preferred embodiment of the utility model includes a drying drum 11, an active oxygen generating device 14 and a light source device 13; the active oxygen generating device 14 is configured to provide active oxygen into the drying drum 11; the light source device 13 is configured to irradiate the active oxygen generated by the active oxygen generating device 14, and the light source device 13 can emit full-spectrum sunlight. The drying drum 11 contains a clothing receiving cavity 111, and the clothing receiving cavity 111 is used to place clothing to be treated. In the air, the active oxygen (O3) generated by the active oxygen generating device 14 can generate hydroxyl radicals (·OH) under the irradiation of the full-spectrum sunlight of the light source device 13. The hydroxyl radicals can comprehensively sterilize and deodorize the clothing in the clothing receiving cavity 111, and can make the clothing produce a slight sunlight smell, thereby improving the user experience. The technical solution of the utility model is used to sterilize and deodorize the clothing, and the effect is good. High temperature is not used, and the material of some clothing can be prevented from being damaged by high temperature.

[0033] Preferably, the wavelength range of the full-spectrum lamp band of the light source device 13 is the 300nm-1000nm band, and the color rendering index Ra is greater than 80. Further, the wavelength range of the full-spectrum lamp band of the light source device 13 is the 350-780nm band, and the color rendering index Ra is greater than 90. Further, the wavelength range of the full-spectrum lamp band of the light source device 13 is the 350nm-780nm band, and the color rendering index Ra is greater than 97. The 350nm-780nm band covers the range of visible light, from ultraviolet light (350nm) to infrared light (780nm), and covers ultraviolet light, infrared light and visible light at the same time, which can sterilize and deodorize, and can also slightly heat clothes to enhance the effect of sunshine smell.

[0034] The Color Rendering Index (CRI) is an indicator used to evaluate the ability of a light source to reproduce the color of an object. Ra is one of the common color rendering indices, which indicates the ability of a light source to reproduce a set of standard colors, ranging from 0 to 100. The higher the value, the better the light source's ability to reproduce colors. When the Ra color rendering index is greater than 80, it means that the color rendering index of the light source is above 80. This is generally considered a relatively good color rendering performance, which helps ensure that the color of an object can be accurately identified under light.

[0035] In the present invention, the wavelength range of the full-spectrum lamp band of the light source device 13 is most preferably 350nm-780nm, and the color rendering index Ra is greater than 97, which most closely simulates sunlight irradiation on clothes, improves the sterilization and deodorization effect of clothes, and enhances the sunshine smell of clothes.

[0036] In a clothes dryer in another preferred embodiment, the full-spectrum lamp band of the light source device 13 includes visible light and UVC band ultraviolet rays, and the UVC band ultraviolet rays will not cause aging of clothes and parts of the clothes dryer.

[0037] The light intensity of the light source device 13 when working is controlled within a preset range to avoid damage to clothes caused by too strong light intensity. The preset range of light intensity can be set by technicians in this field according to actual conditions, for example, the light intensity of sunlight irradiating to the ground at 12:00 noon at a certain temperature.

[0038] Continue reading Figure 1 The clothes dryer includes a pipe 15, both ends of which are connected to the drying drum 11, and the pipe 15 and the drying drum 11 together form a circulation path, and a fan 16 is arranged in the pipe 15. When the fan 16 is started, the active oxygen can circulate in the closed circulation path, so as to prevent the active oxygen from leaking to the outside of the clothes dryer, thereby preventing the active oxygen from causing harm to the human body. At the same time, the fluidity of the air is improved, which is helpful for the treatment of the clothes, so that the sterilization and deodorization effect of the clothes is better.

[0039] In another preferred embodiment, the clothes dryer does not include the fan 16, and axial flow fan blades are arranged inside the drying drum 11. The axial flow fan blades rotate with the rotation of the drying drum 11 and can still play a role in driving the air flow.

[0040] Furthermore, the clothes dryer further comprises a sealing support 17, which is dynamically sealedly connected to the barrel mouth of the drying drum 11, and the sealing support 17 is located between the door body 12 and the drying drum 11 of the clothes dryer, and is used to seal the gap between the drying drum 11 and the door body 12, and the sealing support 17 is formed with a connecting cavity running through it, and the connecting cavity is connected to the drying drum 11, and one end of the drying drum 11 away from the barrel mouth is dynamically sealedly connected to the housing 10 of the clothes dryer; specifically, the sealing support 17 is a sleeve-shaped structure, the left end of the sealing support 17 is fixedly connected to the inner wall of the housing 10, and the right end of the sealing support 17 is dynamically sealedly connected to the drying drum 11, and the clothes dryer further comprises a dynamic sealing part 18, which is a circular ring-shaped structure, the left side of the dynamic sealing part 18 is dynamically sealedly connected to the right side of the drying drum 11, and the right side of the dynamic sealing part 18 is connected to the housing 10, based on which, it is ensured that the circulation passage is in a closed state and does not hinder the rotation of the drying drum 11.

[0041] In addition, the housing 10 is provided with a first hole 101 and a second hole 102, one end of the duct 15 is connected to the end of the drying drum 11 away from the drum mouth through the first hole 101 and the second hole 102, and the other end of the duct 15 is connected to the drying drum 11 through the sealing support 17. Specifically, the duct 15 includes a first air duct 151 and a second air duct 152 that are connected, the first air duct 151 is located inside the housing 10 and below the drying drum 11, the first air duct 151 is connected to the second air duct 152 through the first hole 101, the second air duct 152 is located outside the housing 10, and the second air duct 152 is connected to the closed space formed by the dynamic sealing part 18, the housing 10 and the right side of the drying drum 11 through the second hole 102, and the right side of the drying drum 11 is provided with a plurality of air inlet holes 112, so the second air duct 152 can be connected to the inside of the drying drum 11, and the duct 15 can be connected to the inside of the drying drum 11 regardless of whether the drying drum 11 rotates.

[0042] Those skilled in the art will appreciate that in a preferred embodiment in which the drying drum 11 is arranged in a fixed manner, that is, when the clothes dryer is in operation, the drying drum 11 cannot rotate at all times. In this case, the sealing support 17 and the drying drum 11 may not be connected in a dynamic sealing manner, and the drying drum 11 and the dynamic sealing portion 18 may not be connected in a dynamic sealing manner. Alternatively, the sealing support 17 and the dynamic sealing portion 18 may not be provided, and both ends of the pipe 15 are directly connected to the interior of the drying drum 11, and the pipe 15 is provided in the housing 10. Those skilled in the art may set this by themselves according to actual conditions.

[0043] Furthermore, the left side wall of the second air duct 152 is the right side wall of the box body 10, saving material costs, and the second air duct 152 is buckled on the right side of the box body 10 and covers the second hole 102. Of course, the second air duct 152 can also be a separate tubular structure connected to the second hole 102, and those skilled in the art can set it according to actual conditions.

[0044] It should be noted that the present invention does not impose any limitation on the specific location of the first air duct 151. For example, the first air duct 151 is located above the drying drum 11, and those skilled in the art can set it according to actual conditions.

[0045] In the dryer of the first preferred embodiment, the light source device 13 is connected to the housing 10 and is located in the connecting cavity formed by the sealing support 17. The irradiation direction of the light source device 13 is toward the inside of the drying drum 11. The clothes in the drying drum 11 are irradiated by full-spectrum sunlight, which enhances the effect of sunshine smell. The active oxygen generator 14 is arranged in the pipeline 15. More preferably, the active oxygen generator 14 is arranged in the second air duct 152 and is arranged close to the second hole 102, so that the active oxygen generated by the active oxygen generator 14 can enter the drying drum 11 faster.

[0046] See also Figure 2 The difference between the clothes dryer of the second preferred embodiment and the first preferred embodiment is that the light source device 13 is arranged on the door body 12, and the irradiation direction is toward the inside of the drying drum 11. The rest of the configuration is the same as the first preferred embodiment, and will not be repeated here.

[0047] See also Figure 3 The active oxygen generating device 14 of the utility model includes a connected active oxygen generating component 142 and a driving power supply 141. The driving power supply 141 is a high-voltage driving power supply or a high-voltage power supply board or a high-voltage coil driving device. The active oxygen generating component 142 is an active oxygen generating sheet or an active oxygen generating needle. When the driving power supply 141 is energized, the active oxygen generating component 142 can generate active oxygen, that is, convert oxygen into O3.

[0048] In another preferred embodiment, the active oxygen generating device 14 also includes a first shell and a second shell, the driving power supply 141 is arranged in the first shell, and the active oxygen generating component 142 is arranged in the second shell. The arrangement of the first shell and the second shell facilitates the installation and disassembly of the active oxygen generating device 14. Of course, this is not restrictive, and the active oxygen generating component 142 can also be directly embedded in the pipeline 15. Those skilled in the art can set it according to actual conditions.

[0049] The difference between the dryer of the third preferred embodiment of the utility model and the first preferred embodiment is that the driving power supply 141 is arranged outside the circulation passage, and the active oxygen generating component 142 is arranged inside the circulation passage, that is, the driving power supply 141 is arranged outside the second air duct 152, and the active oxygen generating component 142 is arranged inside the second air duct 152. Based on this, high-temperature airflow is prevented from flowing through the active oxygen generating device 14, and the driving power supply 141 is prevented from being damaged by excessive temperature; the light source device 13 is connected to the sealing support 17, and a fiber filter 21 is also arranged between the pipe 15 and the sealing support 17. The remaining arrangements are the same as those of the first preferred embodiment and will not be repeated here.

[0050] During the drying process, clothes usually release fine fibers and fluff. If these fibers enter the duct 15, they may accumulate on the fan 16, duct 15 and other key components, causing system blockage. By providing a lint filter 21, these tiny particles can be captured and prevented from entering key mechanical and electrical components, helping to maintain the normal operation of the dryer.

[0051] It should be noted that the present invention does not impose any restrictions on the specific locations of the light source device 13 and the active oxygen generating device 14. As long as the light source device 13 is configured to irradiate light into the interior of the drying drum 11 so that the irradiated clothes have a sunshine smell, and the active oxygen generating device 14 can provide active oxygen to the interior of the drying drum 11, the active oxygen generating device 14 can be entirely disposed in the pipeline 15, or partially disposed in the pipeline 15, with the remaining portion disposed outside the pipeline 15. Those skilled in the art can set it themselves according to actual conditions.

[0052] like Figure 4 As shown, in the embodiment where the light source device 13 is arranged on the door body 12 or the sealing support 17, the angle between the irradiation end surface 131 of the light source device 13 and the horizontal line S is a, and the angle a is between 120°-150°. The angle of the irradiation area of ​​the light source device 13 is b, and the angle b is between 30°-60°, so that the irradiation end surface 131 of the light source device 13 faces the inside of the drying drum 11, and the clothes can be irradiated in the maximum range to ensure that the light evenly covers different parts of the clothes, avoids excessive irradiation in some areas and insufficient irradiation in other areas, and allows as many clothes as possible to be irradiated by the light source. The irradiation effect of the clothes inside the drying drum 11 is improved.

[0053] In the embodiment in which the light source device 13 is arranged in the pipe 15, the pipe 15 and the drying drum 11 are both made of transparent materials, so that the light source device 13 can penetrate the pipe 15 to irradiate the full-spectrum sunlight into the drying drum 11. Since the air in the circulation passage is always in a flowing state, the active oxygen generated by the active oxygen generating device 14 may exist in various places in the circulation passage. By setting the pipe 15 and the drying drum 11 to be made of transparent materials, the active oxygen existing in the drying drum 11 can be irradiated, and the decomposition rate of the active oxygen can be improved, thereby generating more hydroxyl free radicals, promoting the effect of sterilization and deodorization, and the full-spectrum sunlight can directly irradiate the clothes, promoting the sunshine smell effect of the clothes.

[0054] In the first to third preferred embodiments, the light irradiation direction of the light source device 13 is toward the clothing holding cavity 111. In this case, the pipe 15 and the drying drum 11 are not set to transparent materials, which can also promote the sunlight smell effect and the sterilization and deodorization effect of the clothes.

[0055] Those skilled in the art will appreciate that the active oxygen generating device 14 may be a device as described in the present invention, or may be other existing devices capable of generating active oxygen, such as an ozone generator. Changes to the structure of the active oxygen generating device 14 do not deviate from the basic principles of the present invention and shall fall within the scope of protection of the present invention.

[0056] It should be noted that the present invention does not impose any limitation on the specific structure of the light source device 13. The light source device 13 may be an LED lamp capable of emitting full-spectrum sunlight, or may be a specific fluorescent tube, metal halide lamp or mercury vapor lamp, etc. It may also be a lighting device including ultraviolet lamp beads, visible light lamp beads and infrared lamp beads. The light source device 13 may also include a lamp capable of emitting full-spectrum sunlight and a movable component for driving the lamp to rotate or move, so that the lamp can be adjusted for illumination, and the illumination is more comprehensive.

[0057] In another preferred embodiment, the clothes dryer further comprises an oxygen storage tank for providing oxygen into the clothes dryer, which helps to generate living oxygen.

[0058] In another preferred embodiment, the clothes dryer further comprises a connected water mist nozzle and a water storage tank, wherein the water mist nozzle is used to provide a trace amount of water molecules into the clothing receiving cavity to promote the generation of hydroxyl free radicals.

[0059] After the active oxygen generator 14 and the light source device 13 are started, the spectrum of the light source device 13 is close to the spectrum of sunlight, especially in the visible light part, the ratio of each wavelength component is similar to that of sunlight, and a photochemical reaction similar to sunlight is produced with the clothing fabric, catalysis, active oxygen, hydroxyl radicals to oxygenate the clothing, and the smell of clothes that have been dried 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 aroma combinations that can be produced are: sweet, citrus, wax, and floral; wax, citrus, fat, and floral; sweet orange, slight grease, honey-like aroma; grease and grass and apple aroma, so as to achieve the smell of sunshine produced by drying clothes and quilts, and then make users happy.

[0060] When in use, the user can turn on the sunshine smell care mode, turn on the light source device 13 and the active oxygen generating device 14, and start the fan 16. The full-spectrum sunlight emitted by the light source device 13 irradiates the clothes to produce a sunshine smell. The active oxygen generating device 14 provides active oxygen to the drying drum 11. Under the irradiation of the full-spectrum light, a part of the active oxygen will be quickly converted into hydroxyl free radicals. The oxidizing ability of hydroxyl free radicals is 1.4 times that of active oxygen, so the effect of removing odor is better. In addition, the oxygenation of clothes by active oxygen and hydroxyl free radicals can enhance the sunshine smell of clothes.

[0061] In the first to third preferred embodiments of the dryer of the utility model, a driving motor 19 and a transmission belt 20 are included. The right side of the drying drum 11 is rotatably connected to the casing 10 through a rotating shaft. The left side of the drying drum 11 is supported by the sealing support 17 for the drum mouth, and the drum mouth and the sealing support 17 are dynamically sealed and connected without hindering rotation. The transmission belt 20 is sleeved on the drying drum 11. When the driving motor 19 drives the transmission belt 20 to rotate, the transmission belt 20 drives the drying drum 11 to rotate. Of course, this is only a preferred setting method to drive the drying drum 11 to rotate. It can also be that the driving motor 19 is set on the right side of the drying drum 11 and is fixedly connected to the casing 10 to directly drive the drying drum 11 to rotate. Those skilled in the art can set it according to actual conditions.

[0062] It should be noted that the present invention does not impose any restrictions on the type of dryer. The dryer may be a hot air dryer, a heat pump dryer, a steam dryer or a rotary dryer, etc. Those skilled in the art may set it according to actual conditions.

[0063] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying 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.
