Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of clothing processing equipment, specifically, it relates to a clothing processing device with drying and sterilization functions. Background Technology
[0002] As living standards continue to improve, people's needs for clothing processing equipment are becoming more refined, no longer limited to just washing clothes. In particular, due to problems such as the smog in northern my country making it unsuitable to dry clothes and the rainy season in southern China making clothes difficult to dry and causing odors, clothing processing equipment with drying functions is becoming increasingly popular.
[0003] Clothing processing equipment with drying function has a drying air duct, which is equipped with a fan and a heating device. The fan sends airflow into the drying air duct, and the airflow is formed into a high-temperature airflow by the heating device in the drying air duct. The high-temperature airflow is sent into the clothing processing drum through the drying air duct, which raises the temperature inside the clothing processing drum to evaporate the moisture on the clothes inside the drum. Then the evaporated water vapor is discharged from the clothing processing drum by the airflow, thus achieving the effect of drying the clothes inside the clothing processing drum.
[0004] However, because moisture may remain inside the clothes drying drum, bacteria, growth, and odors can develop within it. Furthermore, the high-temperature air used in the drying process is limited and cannot completely eliminate these bacteria. Additionally, the high-temperature air during drying cannot remove odors from clothes; in fact, it may even accelerate the spread of odors inside the drying drum.
[0005] In view of this, the present invention is hereby proposed. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a clothing treatment device to improve the sterilization efficiency of the clothing treatment device; another objective of the present invention is to provide a clothing treatment device to remove clothing odors.
[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:
[0008] A clothing processing device with a drying function includes a clothing processing drum; a drying air duct for supplying airflow to the clothing processing drum; a light irradiation chamber provided in the drying air duct, through which at least part of the airflow enters the clothing processing drum; and a photoplasma tube provided in the light irradiation chamber for irradiating and sterilizing the airflow flowing into the clothing processing drum.
[0009] Furthermore, the drying air duct has a disc-shaped air outlet cavity, and the air outlet cavity is provided with a partition rib, which divides the disc-shaped air outlet cavity into two parts; the first part with a smaller cross-sectional area constitutes the light irradiation cavity, and a photoplasma tube is provided on the outer periphery of the light irradiation cavity and inserted radially into the light irradiation cavity.
[0010] Furthermore, the center of the disc-shaped air outlet cavity is provided with an annular dividing rib, and the outer part of the annular dividing rib is provided with a first dividing rib and a second dividing rib arranged at an angle. The part between the first dividing rib and the second dividing rib constitutes the light irradiation cavity. The first dividing rib is provided with a notch to introduce airflow into the light irradiation cavity, and the photoplasma tube is set close to the second dividing rib.
[0011] Furthermore, the drying air duct also includes an air inlet chamber equipped with a fan, and the air inlet chamber is directly connected to the second part of the air outlet chamber via a connecting chamber that extends obliquely upward; the first partition rib separates the connecting chamber from the light irradiation chamber, and the first partition rib is provided with a notch that connects the two sides, and at least part of the airflow flowing into the air inlet chamber flows into the light irradiation chamber through the notch; the notch is located near the center of the annular air outlet chamber relative to the photoplasma tube.
[0012] Furthermore, a heater is provided in the second part of the annular air outlet cavity, which is directly opposite the air outlet end of the connecting cavity and is used to directly heat the blown airflow; the heater is located near the notch on the first partition rib and is used to heat the airflow flowing into the illumination cavity.
[0013] Furthermore, the optical plasma tube is columnar, and the end of the columnar optical plasma tube is provided with a mounting seat that is at least partially radially protruding outside the drying air duct. The radially protruding part of the mounting seat is fixed to the outer wall of the drying air duct.
[0014] Furthermore, the mounting base has radially outward protruding fixing ribs on its radially opposite sides. Both fixing ribs are in contact with the outer wall of the drying air duct. The fixing ribs are provided with through holes. Screws pass through the through holes and are fixed to the drying air duct to fix the mounting base on the drying air duct.
[0015] Furthermore, a shock-absorbing washer is fitted around the outer periphery of the columnar plasma tube, and the shock-absorbing washer is clamped between the fixing base and the drying air duct.
[0016] Furthermore, a plurality of air outlets are provided on one side of the annular air outlet cavity, at least one of which is a first air outlet connected to the light illumination cavity, and the remaining air outlets are second air outlets connected to the second part; the first air outlet is opened opposite to at least a portion of the columnar plasma tube in the light illumination cavity.
[0017] Furthermore, the second dividing rib has an outwardly protruding curved part near the outer periphery of the annular air outlet cavity, and the columnar plasma tube is located in the area enclosed by the curved part; the first air outlet is a circular opening located on one side of the area enclosed by the curved part.

[0019] 1. In this invention, a photo-plasma tube irradiates the hot air in the drying duct, forming hot air with sterilization and deodorization functions in the drying duct. The hot air with sterilization and deodorization functions is rapidly diffused into the clothing processing drum through the drying duct. While ensuring the drying function of the clothing processing equipment, the clothing is subjected to sterilization and deodorization processes, thereby improving the utilization efficiency of the hot air.
[0020] 2. In this invention, the photoplasma tube is set in an independent chamber within the drying air duct, so that the photoplasma tube can irradiate part of the airflow flowing into the clothes processing drum, thereby reducing the power of the photoplasma tube and improving the photo-sterilization effect on the airflow, thus significantly improving the sterilization and deodorization efficiency of the photoplasma tube in the clothes processing drum.
[0021] 3. In this invention, the photoplasma tube has UVC and / or UVD ultraviolet light. UVD ultraviolet light can efficiently excite oxygen and water in the air to produce photoplasma clusters, and UVC ultraviolet light has a highly efficient sterilization effect, so that the microorganisms attached to the clothes in the clothes treatment tube and inside it are completely killed.

[0036] Example 1
[0037] like Figures 1 to 7 As shown, this embodiment of the invention provides a clothing processing device with a drying function, including a housing 1, a clothing processing cylinder 2 installed inside the housing, and a drying air duct 4 for sending hot air into the clothing processing cylinder 2. The air outlet of the drying air duct 4 is connected to the rear of the clothing processing cylinder 2, and a photo-plasma tube 3 for irradiating the hot air inside the drying air duct 4 is provided inside the drying air duct 4.
[0038] In this embodiment, a fan 9 is installed inside the drying duct 4. The fan 9 drives airflow through the drying duct 4 to deliver air into the clothes processing drum 2. A heater 5 is also installed inside the drying duct 4 to heat the flowing airflow, forming a high-temperature dry airflow that flows back into the clothes processing drum 2 to dry the clothes inside. In this embodiment, the clothes processing equipment can be a direct-vent dryer, a circulating condenser dryer, etc.; this embodiment uses a direct-vent dryer as an example for further explanation.
[0039] like Figures 1 to 5 As shown, in this embodiment, the air inside the clothes processing drum 2 flows into the drying duct 4 and is irradiated by the photo-plasma tube 3 installed in the drying duct 4, so that an airflow with sterilization and deodorization functions is formed in the drying duct 4, and then diffuses into the clothes processing drum 2 for sterilization and deodorization treatment of the clothes inside the drum.
[0040] In this embodiment, the photoplasma tube 3 can emit photoplasma and ion clusters. The photoplasma tube 3 irradiates the hot air in the drying duct 4. The emitted photoplasma and ion cluster light decompose oxygen and water molecules in the air into hydroxide ions, free oxygen atoms, superoxide ions and other oxidants, thereby forming sterilizing air to sterilize the clothes and decompose harmful impurities in the air inside the clothes treatment drum 2 into inert compounds such as carbon dioxide and water. The odor of the clothes is quickly and easily removed.
[0041] like Figures 1 to 5As shown, in this embodiment, the photoplasma tube 3 is located in the light-illuminating cavity 44 isolated in the air outlet cavity 42 of the drying air duct 4, so that the photoplasma tube 3 can irradiate part of the airflow returning into the clothes processing drum 2. When the airflow flows through the light-illuminating cavity 44 where the photoplasma tube 3 is located, the photoplasma and ion clusters emitted by the photoplasma tube 3 decompose oxygen and water molecules in the air into hydroxide ions, free oxygen atoms, superoxide ions and other oxidants, and generate a certain amount of ozone. When the airflow has a certain amount of heat, the ozone is easily decomposed by heat, thereby ensuring that the photoplasma with a low ozone concentration disinfects and sterilizes the environment inside the clothes processing drum 2 of the clothes processing equipment.
[0042] In this embodiment, a portion of the air outlet cavity 42 is divided into a light irradiation cavity 44 by a partition rib 45. A photoplasma tube 3 is installed inside the light irradiation cavity 44. An air inlet and an air outlet are respectively located on opposite sides of the light irradiation cavity 44. The photoplasma tube 3 is positioned near or directly at the air outlet, so that it irradiates light into the light irradiation cavity 44, ensuring that all airflow passing through the light irradiation cavity 44 is irradiated, thereby effectively improving sterilization and deodorization efficiency. In this embodiment, the ion clusters generated by the photoplasma tube 3 transform airborne particles into oxidants. When encountering harmful substances, the overall photoplasma clusters are highly active. Under the same polluted environment, it destroys organic matter 180 times faster than ultraviolet light and 2000 times faster than ozone, removing biological pollutants from the air—killing and destroying bacteria, viruses, and mold in the air and on object surfaces, reducing the spread of germs in the air.
[0043] In this embodiment, the drying air duct 4 has an air inlet chamber 40, a connecting chamber 41 and an air outlet chamber 42 connected in sequence; a fan 9 is installed in the air inlet chamber 40, which draws external air into the drying air duct 4 and provides flow force to the air inlet airflow.
[0044] In this embodiment, the connecting cavity of the drying air duct 4 connects the air inlet cavity 40 and the air outlet cavity 42, so that the airflow drawn by the fan 9 enters the air outlet cavity 42. The air outlet cavity 42 is equipped with a heater 5, which heats the airflow flowing into the air outlet cavity 42 to form a high-temperature airflow. The high-temperature airflow flows into the clothes processing cylinder 2 from the rear opening of the cylinder, and performs high-temperature drying treatment on the clothes in the clothes processing cylinder 2. The airflow flowing into the clothes processing cylinder 2 is directly irradiated, so that the sterilization and deodorization airflow formed by the photo-plasma tube 3 can be directly returned to the cylinder, reducing the diffusion of the sterilization and deodorization airflow formed by the photo-plasma tube irradiation in the drying air duct, thereby improving the sterilization and deodorization efficiency of the photo-plasma tube.
[0045] In this embodiment, the fan 9 causes the air inside the drying duct 4 and the clothes processing drum 2 to flow and form an airflow. During the airflow in the drying duct 4, the photo-plasma tube 3 irradiates the air to form sterilizing air containing oxides, so as to sterilize the clothes processing equipment.
[0046] In this embodiment, the heater 5 inside the drying air duct 4 is positioned close to the photoplasma tube 3 so that the heater 5 can heat the space near the photoplasma tube 3, which helps to reduce the ozone concentration in the sterilization air.
[0047] In this embodiment, the light plasma and ion cluster light emitted by the photoplasma tube 3 decompose oxygen and water molecules in the air into hydroxide ions, free oxygen atoms, superoxide ions and other oxidants. However, along with the generation of ozone, excessive ozone can strongly irritate the human respiratory tract, causing symptoms such as sore throat, chest tightness and cough. The hot air in the drying duct 4 causes the ozone to decompose by heat, which can effectively reduce the ozone concentration in the circulating airflow.
[0048] like Figures 1 to 5 As shown in the figure, this embodiment introduces a clothing processing device with a drying function, including a clothing processing drum 2; a drying air duct 4 for supplying airflow to the clothing processing drum 2; a light irradiation chamber 44 provided in the drying air duct 4, through which at least part of the airflow enters the clothing processing drum 2; and a photo-plasma tube 3 provided in the light irradiation chamber 44 to irradiate and sterilize the airflow flowing into the clothing processing drum 2.
[0049] In this embodiment, the drying duct 4 is formed by the clamping space of two vertical plates located at the rear of the garment processing equipment. The two vertical plates are a back plate 102 and a back cover plate 103. A rubber gasket 104 is provided between the back plate 102 and the back cover plate 103 to seal the drying duct formed by the two plates. A baffle is provided in the gap between the back plate 102 and the back cover plate 103 to separate the gap between the two plates and form a vertically arranged drying duct 4. The lower part of the drying duct 4 is an air inlet 40, the upper part is an air outlet 42, and the middle part is a connecting cavity 41. At the same time, an air inlet 48 is opened on the back plate 102 on the lower front side of the drying duct 4 to send the outside air into the drying duct 4 via the fan 9. In addition, multiple air outlets 43 are opened on the back plate 102 on the upper front side of the drying duct 4 to send the airflow from the air outlet 42 into the garment processing cylinder 2.
[0050] like Figures 2 to 5As shown, in this embodiment, the drying air duct 4 has a disc-shaped air outlet cavity 42. The annular air outlet cavity 42 is provided with radially extending partition ribs 45, which divide the disc-shaped air outlet cavity 42 into two fan-shaped areas. The first part 421 constitutes the light irradiation cavity 44. The outer peripheral sidewall of the disc-shaped air outlet cavity 42 is provided with a photoplasma tube 3 that is radially inserted into the light irradiation cavity 44.
[0051] Preferably, the circumferential dimension of the first part 421 is much smaller than the circumferential dimension of the second part 422, so that the photoplasma tube 3 illuminates only the smaller first part 421, thereby improving the illumination effect of the airflow within the first part 421.
[0052] like Figures 3 to 5 As shown, in this embodiment, the center of the disc-shaped air outlet cavity 42 is provided with an annular partition rib 453, and the outer part of the annular partition rib 453 is provided with a first partition rib 451 and a second partition rib 452 arranged at an interval. The fan-shaped part between the first partition rib 451 and the second partition rib 452 constitutes the illumination cavity 44. That is, the first partition rib 451, the second partition rib 452, the annular partition rib 453 and the outer peripheral sidewall of the air outlet cavity 42 together form two fan-shaped areas of different sizes, namely the first part 421 and the second part 422, wherein the smaller area of the first part 421 is the illumination cavity 44.
[0053] In this embodiment, a notch 46 is provided at the first partition rib 451, which is connected to the air inlet cavity 40 via the connecting cavity 41, so that the air inlet of the illumination cavity 44 is located on the side of the first partition rib 451; at the same time, in order to improve the illumination efficiency in the illumination cavity 44, the photoplasma tube 3 is placed close to the second partition rib 452, so that the airflow flowing into the illumination cavity 44 can be fully irradiated by the photoplasma tube 3, thereby improving the illumination effect.
[0054] In this embodiment, the drying air duct 4 further includes an air inlet cavity 40 equipped with a fan 9. The air inlet cavity 40 is directly connected to the second part 422 of the air outlet cavity 42 via a connecting cavity 41 that extends obliquely upward. A first partition rib 451 separates the connecting cavity 41 from the illumination cavity 44. The first partition rib 451 is provided with a notch 46 that connects the two sides. At least part of the airflow flowing into the air inlet cavity 40 flows into the illumination cavity 44 through the notch 46, so as to connect the first part 421 branch of the air inlet cavity 40 and the air outlet cavity 42 through the notch 46. The notch 46 is located near the center of the annular air outlet cavity 42 relative to the photoplasma tube 3.
[0055] Preferred, such as Figures 1 to 5 As shown, in this embodiment, the first partition rib 451 extends to the air inlet cavity 40 along the approximately tangential direction of the annular partition rib 453 to form a connecting cavity 41 extending along the common tangent of the air inlet cavity 40 and the air outlet cavity 42.
[0056] In this embodiment, a heater 5 is provided in the second part 422 of the annular air outlet cavity 42. The heater 5 is directly opposite the air outlet end of the connecting cavity 41 and is used to directly heat the airflow blown in. At the same time, the heater 5 is located near the opening 46 and can be used to heat the airflow flowing into the light illumination cavity 44 to increase the temperature of the airflow flowing through the light illumination cavity 44.
[0057] like Figures 1 to 5 As shown, in this embodiment, the second separating rib 452 extends along a wavy line that bends to both sides until it reaches the outer periphery of the annular air outlet cavity 42. In this embodiment, the second separating rib 452 has two curved portions 47 near the outer periphery of the annular air outlet cavity 42, one protruding outward and the other concave inward. The columnar photoplasma tube 3 is disposed within the area enclosed by the curved portions 47. By placing the photoplasma tube 3 in the curved portions 47, the curved portions 47 can guide the airflow in the illumination cavity 44 to form a vortex near the photoplasma tube 3, prolonging the residence time of the airflow there and further improving the illumination effect.
[0058] like Figures 1 to 7 As shown, in this embodiment, a plurality of air outlets 43 are provided on one side of the annular air outlet cavity 42. Each air outlet 43 is used to guide the airflow in the air outlet cavity 42 into the clothes processing drum 2. At least one air outlet 43 of the annular air outlet cavity 42 is a first air outlet 431 connected to the light irradiation cavity 44, and the remaining air outlets 43 are second air outlets 432 connected to the second part 422. The first air outlet 431 is opened opposite to at least a portion of the columnar plasma tube 3 in the light irradiation cavity 44. Thus, the columnar plasma tube 3 can irradiate the area of the first air outlet 431, so that all the airflow flowing into the clothes processing drum 2 can be irradiated by the plasma tube 3, thereby increasing the amount of gas in the clothes processing drum 2 after irradiation, and thus achieving the purpose of improving the sterilization and deodorization effect.
[0059] In this embodiment, the first air outlet 431 is located on the offset side of the notch, and is closer to the center of the air outlet cavity 42 than the notch; at the same time, the first air outlet 431 and the notch 46 are both on the same side of the photoplasma tube 3, so as to improve the irradiation effect of the photoplasma tube on the airflow flowing through the light irradiation cavity 44.
[0060] Preferably, the first air outlet 431 can be located at the overlapping position of the columnar plasma tube 3, so that the air outlet of the light cavity 44 is located at the farthest side relative to the air inlet, thereby extending the flow distance of the airflow in the light cavity 44 and improving the light effect; at the same time, the second air outlet 432 is opened at the plasma tube 3, so that the airflow flowing into the clothes treatment drum 2 can be completely irradiated by the plasma tube 3, thereby further increasing the amount of gas in the clothes treatment drum 2 after light irradiation, thereby achieving the purpose of improving the sterilization and deodorization effect (not shown in the attached drawings).
[0061] In this embodiment, the first air outlet 431 is a circular opening located on one side of the area enclosed by the curved portion 47; the cross-sectional area of the circular opening is smaller than that of the second air outlet 432; the radial dimension of the first air outlet 431 formed by the circular opening is less than or equal to the width of the notch 46 and approximately equal to the extension length of the photoplasma tube 3 in the illumination cavity 44.
[0062] like Figures 1 to 7 As shown, in this embodiment, the photoplasma tube 3 is columnar, and its end is provided with a mounting base 321 that is at least partially radially protruding outside the drying duct 4. The radially protruding part of the mounting base 321 is fixed to the outer wall of the drying duct 4. In this embodiment, the mounting base 321 has radially outward protruding fixing ribs 323 on its radially opposite sides. Both fixing ribs 323 are in contact with the outer wall of the drying duct 4. The fixing ribs 323 are provided with through holes, and screws pass through the through holes and are fixed to the drying duct 4 to fix the mounting base 321 to the drying duct 4.
[0063] Preferably, the outer wall of the drying duct 4 is provided with an installation groove, the bottom of the installation groove is provided with a through hole for the columnar plasma tube 3 to pass through, the mounting base has a limiting part that protrudes radially from the through hole and contacts the inner wall of the installation groove, and a shock-absorbing washer 322 made of elastic material is sleeved on the outer periphery of the limiting part, and the shock-absorbing washer 322 is clamped between the fixing base 321 and the outer wall of the drying duct 4.
[0064] The shock-absorbing washer 322 is a cylindrical shape that coaxially passes through the through hole in the side wall of the drying air duct 4, and the photoplasma tube 3 is located inside the shock-absorbing washer 322. The outer wall of the shock-absorbing washer 4 is provided with a notch groove 324, which is inserted into the side wall of the drying air duct 4 around the through hole to achieve axial fixed installation between the shock-absorbing washer 322 and the drying air duct 4. The outer wall of the mounting base 321 is provided with a protruding rib 326, which is inserted into the annular limiting groove 325 provided on the inner peripheral wall of the cylindrical shock-absorbing washer 322 to achieve axial fixed installation between the photoplasma tube 3 and the shock-absorbing washer 322.
[0065] In this embodiment, the photoplasma tube 3 can be an ultraviolet light tube with at least two wavelengths: UVC and UVD.
[0066] Ultraviolet (UV) radiation can be categorized by wavelength into vacuum UV (ultra-low frequency, UVD), short-wave germicidal UV (low frequency, UVC), medium-wave erythema-inducing UV (medium frequency, UVB), and long-wave black spot-inducing UV (high frequency, UVA). Among these, the UVC band has a wavelength of 200–275 nm, with the 253.7 nm UVC band exhibiting highly effective sterilization. The UVD band has a wavelength of 100–200 nm, with the 185 nm UVD band capable of exciting oxygen and water in the air to produce photoplasma.
[0067] In this embodiment, a control device 10 is further included. The control device 10 is connected to the photo-plasma tube 3 to control the photo-plasma tube 3 to irradiate the air flow in the drying air duct 4. The control device 10 can be independently installed on the outer wall of the drying air duct 4; or it can be integrally arranged on the control board of the laundry treatment device.
[0068] In this embodiment, a photo-plasma concentration detection device is provided in the drying air duct 4 or in the laundry treatment cylinder 2. The photo-plasma concentration detection device is used to detect whether the photo-plasma concentration in the drying air duct 4 or the photo-plasma concentration inside the laundry treatment cylinder 2 into which the sterilizing gas is introduced meets the sterilization requirements. The photo-plasma concentration detection device is a concentration sensor (not marked in the drawings).
[0069] In this embodiment, an odor detection device is provided inside the laundry treatment cylinder 2. The odor detection device is used to detect the odor concentration and taste concentration of the laundry treatment cylinder 2 or the clothes inside it to precisely control the operation of the photo-plasma generation module.
[0070] In this embodiment, the photo-plasma concentration detection device and the odor detection device are respectively connected to the control device 10. The control device 10 receives the photo-plasma concentration detected by the photo-plasma concentration detection device and the odor concentration and taste concentration values detected by the odor detection device. Based on the obtained photo-plasma concentration, odor concentration and taste concentration values, the control device 10 controls the working time of the photo-plasma tube 3 to ensure that the photo-plasma concentration in the drying air duct 4 meets the requirements of sterilization and odor removal.
[0071] Through the above-mentioned laundry treatment device, the photo-plasma tube 3 has UVC ultraviolet rays and / or UVD ultraviolet rays. The UVD band ultraviolet rays can efficiently excite oxygen and water in the air to generate photo-plasma clusters, and the UVC band ultraviolet rays have a high-efficiency sterilization effect, so that the microorganisms attached to the laundry treatment cylinder 2 and the clothes inside it are completely killed.
[0072] In this embodiment, the photo-plasma tube 3 can also be a wide-waveband photon tube. The wide-waveband photon tube emits light with a balanced energy in a specific waveband, and the wavelength is 100nm - 300nm.
[0073] In this embodiment, a photocatalytic layer is provided in the drying air duct 4. The wide-waveband photon tube is arranged on one side of the photocatalytic net, or the wide-waveband photon tube has a photocatalytic layer inside. The photocatalytic layer is composed of a nano-scale noble metal catalytic material. Under the catalysis of a variety of specific nano-scale noble metal media, the wide-waveband photon tube irradiates the air, generating a large amount of hydroxyl ions, superoxide ions, hydrogen peroxide and pure negative oxygen ions, forming photo-hydrogen ions, which can quickly and effectively kill more than 99% of bacteria, viruses and molds in the air and remove the odors in the air, achieving the effect of purifying the air.
[0074] In this embodiment, the wide-wave photon tube can be a broadband ultraviolet light tube. Compared with irradiating air with an ultraviolet light tube having a UVC ultraviolet and / or UVD ultraviolet band, under the catalysis of a variety of noble metal media at a specific nanoscale, irradiating air with the broadband ultraviolet light tube can generate a large amount of hydroxyl ions, superoxide ions, hydrogen peroxide and pure negative oxygen ions, improving the sterilization effect.
