Description

Technical Field

[0001] The present invention relates to the technical field of ultraviolet sterilization, and more specifically, to an ultraviolet sterilization device, a sterilization method thereof, and an air-conditioning unit. Background Art

[0002] The application of ultraviolet sterilization technology on air-conditioning machines is becoming a trend. Currently, there are two ultraviolet sterilization solutions for air-conditioning machines in the market. One is to install a traditional quartz ultraviolet mercury lamp inside the air-conditioning machine, and the other is to install UVC-LED lamp beads that emit ultraviolet light inside the air-conditioning machine.

[0003] Due to the advantages of uniform ultraviolet radiation distribution, no blind area, and no dead angle in the radiation area of the quartz ultraviolet mercury lamp, 360° ultraviolet radiation sterilization can be achieved within its installation area. However, since the service life of the quartz ultraviolet mercury lamp is only about 5000 hours, the quartz ultraviolet mercury lamp still has disadvantages such as short service life, long startup time, easy mercury pollution to the environment, and high maintenance cost.

[0004] Although the UVC-LED lamp beads have advantages such as energy conservation, environmental protection, long service life, and fast startup speed, their radiation is unilateral and directional, that is, they only radiate in the positive direction of the LED lamp beads. Therefore, the UVC-LED lamp beads cannot achieve 360° radiation without blind areas and dead angles.

[0005] Although selecting UVC-LED lamp beads with a large radiation angle, such as lamp beads with a luminous angle of 120°, can expand the radiation range to a certain extent, there is still a problem of uneven radiation intensity distribution in the radiation space, that is, the radiation density in the radiation center area is the highest, the radiation density in the surrounding area is low, and the farther away from the center area, the lower the radiation density. Summary of the Invention

[0006] In view of this, the present invention provides an ultraviolet sterilization device, a sterilization method thereof, and an air-conditioning unit to improve the uniformity of ultraviolet radiation intensity distribution while expanding the ultraviolet radiation range.

[0036] The above is the core idea of the present invention. To make the above objects, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] An embodiment of the present invention provides an ultraviolet sterilization device, as Figure 1 shown, including a plurality of LED light sources 1 and a rotating body 2.

[0038] Among them, the LED light source includes an LED substrate 10 and a plurality of LED lamp beads 11 that emit ultraviolet light and are arranged on the LED substrate 10. Optionally, the LED substrate 10 includes a heat dissipation aluminum substrate, and the LED lamp beads 11 include UVC-LED lamp beads that emit short-wave ultraviolet light.

[0039] The rotating body 2 has at least three surfaces arranged around a rotation axis 3, and at least one LED light source 1 is arranged on each surface so that the LED light source 1 rotates around the rotation axis 3. Among them, the LED substrate 10 of the LED light source 1 can be fixed on the surface of the rotating body 2 by bonding or other means. The rotation axis 3 is fixedly connected to the rotating body 2 so that the rotation axis 3 drives at least three surfaces and the LED light sources 1 on at least three surfaces to rotate.

[0040] It should be noted that the number of LED light sources 1 on each surface and the number of LED lamp beads 11 in the LED light source 1 can be set according to the actual application scenario and will not be elaborated here. In some embodiments of the present invention, only the case where the number of LED light sources 1 on each surface is equal to 1 and the number of LED lamp beads 11 in each LED light source 1 is equal to 3 is taken as an example for illustration.

[0041] In some embodiments of the present invention, as Figure 1As shown, the rotating body 2 is a regular triangular prism, that is, the rotating body 2 has three surfaces S1, S2, and S3 arranged around the rotation axis 3, and at least one LED light source 1 is arranged on each surface to enable the LED light source 1 to rotate around the rotation axis 3. Based on this, by rotating the LED light source 1 around the rotation axis 3, the LED light source 1 realizes 360° rotation and radiation, thereby expanding the ultraviolet radiation range of the LED light source 1 and the ultraviolet sterilization device.

[0042] Moreover, since at least one LED light source 1 is arranged on each surface of the rotating body 2, and the multiple LED lamp beads 11 on the LED light source 1 are arranged in sequence and evenly along the axial direction X of the rotation axis, it is possible to make the ultraviolet light emitted by the LED lamp beads 11 evenly distributed in the axial direction X of the rotation axis 3. In addition, the light-emitting angle of the LED lamp beads 11 is greater than or equal to 120° to make the ultraviolet light evenly distributed in the rotation direction Y of the rotation axis 3.

[0043] Of course, the present invention is not limited to this. In some other embodiments, the rotating body 2 can also be a regular quadrangular prism, that is, the rotating body 2 has four surfaces arranged around the rotation axis 3, and at least one LED light source 1 is arranged on each surface to enable the LED light source 1 to rotate around the rotation axis 3. At this time, the light-emitting angle of the LED lamp beads 11 can be greater than or equal to 90°. Of course, in some other embodiments, the rotating body 2 can also be a regular polygonal prism such as a regular pentagonal prism, which will not be elaborated here.

[0044] It can be understood that the more surfaces the rotating body 2 has arranged around the rotation axis 3, the smaller the light-emitting angle of the LED lamp beads 11 can be. Optionally, the minimum light-emitting angle of the LED lamp beads 11 is equal to 360° divided by the number of surfaces of the rotating body 2 arranged around the rotation axis 3.

[0045] In some embodiments of the present invention, as Figure 2 shown, the ultraviolet sterilization device further includes a plurality of wind turbine blades 4, and the plurality of wind turbine blades 4 are respectively arranged on at least three surfaces to drive the rotation axis 3 to rotate through the wind turbine blades 4, and drive at least three surfaces and the LED light sources 1 on at least three surfaces to rotate around the rotation axis 3 through the rotation axis 3.

[0046] Optionally, as Figure 2 shown, two wind turbine blades 4 are arranged on each surface, and the two wind turbine blades 4 are respectively arranged on both sides of the rotation axis 3. Of course, the present invention is not limited to this. In some other embodiments, three or more wind turbine blades 4 can be arranged on each surface, and the plurality of wind turbine blades 4 are evenly distributed on the surface along the axial direction X of the rotation axis.

[0047] Moreover, as Figure 2As shown, the wind turbine blade 4 is a sheet-like structure with a certain bending curvature, and the wind turbine blade 4 bends towards the rotation direction Y to drive the rotating shaft 3 to rotate in the rotation direction Y.

[0048] Based on any of the above embodiments, in some embodiments of the present invention, as Figure 3 shown, the ultraviolet sterilization device further includes a rotating motor 5. The rotating motor 5 is connected to one end of the rotating shaft 3, and the rotating motor 5 drives the rotating shaft 3 to rotate, so as to drive at least three surfaces and the LED light sources 1 on at least three surfaces to rotate around the rotating shaft 3 through the rotating shaft 3.

[0049] That is to say, the ultraviolet sterilization device provided by the embodiments of the present invention can not only drive the rotating shaft 3 to rotate through the wind turbine blade 4, but also drive the rotating shaft 3 to rotate through the rotating motor 5 to achieve 360° sterilization. Of course, the present invention is not limited thereto. In other embodiments, the rotating shaft 3 can also be driven to rotate by other power devices, which will not be elaborated here.

[0050] Based on any of the above embodiments, in some embodiments of the present invention, as Figure 3 shown, it further includes a conductive component 6. Among them, the conductive component 6 is nested on one side of the rotating shaft 3, and the conductive component 6 is electrically connected to the LED substrate 10 of the LED light source 1 to supply power to the LED substrate 10 through the conductive component 6 and drive the LED lamp beads 11 to emit light.

[0051] Optionally, the conductive component 6 includes a conductive slip ring or a conductive bearing, so that the conductive component 6 rotates with the rotating shaft 3 to avoid the risk of the wires connected to the conductive component 6 being wound around the rotating shaft 3 and causing damage to the wires.

[0052] It should be noted that the conductive component 6 can be directly electrically connected to the LED substrate 10 to supply power to the LED substrate 10, or can be electrically connected to the LED substrate 10 through the rotating shaft 3 to supply power to the LED substrate 10. At this time, the rotating shaft 3 needs to be made of a conductive material such as metal. It should also be noted that the conductive component 6 also needs to be electrically connected to the power supply so that the power supply can supply power to the LED substrate 10 through the conductive component 6.

[0053] In some embodiments of the present invention, as Figure 3 shown, the ultraviolet sterilization device may further include fixing components such as a base 7, a fixed shaft seat 8, a first fixing bracket 21, and a second fixing bracket 22. Among them, the fixed shaft seat 8, the first fixing bracket 21, and the second fixing bracket 22 are installed on the base 7. The fixed shaft seat 8 is used to fix the rotating shaft 3, the first fixing bracket 21 is used to fix the conductive component 6, and the second fixing bracket 22 is used to fix the rotating motor 5.

[0054] The ultraviolet sterilization device provided by the embodiment of the present invention uses the LED lamp beads 11 that emit ultraviolet light as the light source, which has the advantages of energy conservation, environmental protection, long service life, fast startup speed, etc. Moreover, by arranging the LED light source 1 on the rotating body 2, not only the radiation range of the ultraviolet light of the ultraviolet sterilization device is expanded, but also the uniformity of the radiation intensity distribution of the ultraviolet sterilization device is improved.

[0055] The embodiment of the present invention also provides an ultraviolet sterilization method, which is applied to the ultraviolet sterilization device provided in any one of the above embodiments. As Figure 4 shown, the method includes:

[0056] S101: Arrange the LED light source on at least three surfaces of the rotating body arranged around the rotation axis. The LED light source includes an LED substrate and a plurality of LED lamp beads that emit ultraviolet light arranged on the LED substrate;

[0057] S102: Drive the LED light source to rotate around the rotation axis through the rotation axis.

[0058] As Figure 1 shown, driving the LED light source 1 to rotate around the rotation axis 3 through the rotation axis 3 can enable the LED light source to rotate and radiate 360°, thereby expanding the ultraviolet radiation range of the ultraviolet sterilization device. And, since at least one LED light source is arranged on each surface of the rotating body, and each LED light source has a plurality of LED lamp beads that emit ultraviolet light, therefore, not only can the radiation intensity distribution of the ultraviolet light on each surface of the rotating body be made more uniform, but also the radiation intensity distribution of the ultraviolet light on the rotation path can be made more uniform, thereby improving the uniformity of the radiation intensity distribution of the ultraviolet sterilization device.

[0059] In some embodiments of the present invention, driving the LED light source to rotate around the rotation axis through the rotation axis includes: driving the rotation axis to rotate through the wind turbine blades or the rotating motor, and driving the LED light source to rotate around the rotation axis through the rotation axis.

[0060] That is, in some embodiments of the present invention, as Figure 2 shown, the rotation axis 3 can be driven to rotate through the wind turbine blades 4, and the LED light source 1 can be driven to rotate around the rotation axis 3 through the rotation axis 3. In other embodiments of the present invention, as Figure 3 shown, the rotation axis 3 can be driven to rotate through the rotating motor 5, and the LED light source 1 can be driven to rotate around the rotation axis 3 through the rotation axis 3. Of course, in other embodiments of the present invention, the rotation axis 3 can be driven to rotate through other power devices, which will not be elaborated here.

[0061] The embodiment of the present invention also provides an air conditioner unit, and the air conditioner unit includes the ultraviolet sterilization device provided in any one of the above embodiments. Optionally, the ultraviolet sterilization device can be arranged inside the indoor unit of the air conditioner unit to sterilize the inside of the indoor unit.

[0062] In some embodiments of the present invention, the ultraviolet sterilization device is installed on the air flow path inside the air conditioner unit, that is, on the necessary path of the air flow inside the air conditioner unit, so as to sterilize the air flow inside the air conditioner unit. When the LED light source in the ultraviolet sterilization module rotates 360°, 100% contact between high-intensity ultraviolet radiation and the air flow of the air conditioner unit is achieved. By sterilizing the air flow, the ultraviolet radiation range is extended to the limit, achieving ultraviolet radiation sterilization without dead angles and blind areas, thus completely overcoming the defect of unidirectional radiation of UVC-LED lamp beads. Moreover, it achieves the same sterilization effect as traditional quartz ultraviolet mercury lamps, and has the advantages of energy conservation, environmental protection, longer service life, and fast startup speed.

[0063] In some embodiments of the present invention, such as Figure 5 and Figure 6 shown, the ultraviolet sterilization device 23 is installed inside the cross-flow fan 24 of the air conditioner unit. The rotating shaft 3 of the rotating body of the ultraviolet sterilization device 23 is connected to the fixed shaft 25 of the cross-flow fan 24, so that the fixed shaft 25 drives the rotating shaft 3 to rotate, and drives at least three surfaces and the LED light sources 1 on at least three surfaces to rotate around the rotating shaft 3 through the rotating shaft 3.

[0064] That is to say, when the cross-flow fan 24 rotates 360° around the fixed shaft 25, the fixed shaft 25 will drive the rotating shaft 3 to rotate, so that the LED light sources 1 on at least three surfaces rotate around the rotating shaft 3, that is, the LED light sources 1 rotate 360°, and then the components such as evaporator fins in the irradiation area of the ultraviolet light emitted by the LED light sources 1 can be sterilized.

[0065] It should be noted that, as Figure 5 shown, one side of the rotating shaft 3 is connected to the fixed shaft 25, and the other side of the rotating shaft 3 is connected to the conductive component 6, and the conductive component 6 is electrically connected to the power supply of the air conditioner unit, so as to supply power to the LED substrate through the power supply inside the air conditioner unit and drive the LED lamp beads to emit light.

[0066] In Figure 5 the structure shown, since the rotating shaft 3 is driven by the fixed shaft 25 to rotate, therefore, the ultraviolet sterilization device may not have power devices such as wind wheel blades 4 and rotating motors 5 and fixed structures such as a base 7, a fixed shaft seat 8, a first fixing frame 21 and a second fixing frame 22, thus simplifying the structure of the ultraviolet sterilization device and reducing the cost of the ultraviolet sterilization device. And, setting the ultraviolet sterilization device inside the cross-flow fan 24 results in less change to the internal structure of the air conditioner unit, which is more conducive to installation.

[0067] In some other embodiments of the present invention, the ultraviolet sterilization device can also be installed at the air outlet of the air conditioner unit, such as at the air outlet of the indoor air conditioner or the air outlet of the central air conditioner, such asFigure 7 and Figure 8 As shown, the ultraviolet sterilization device 23 is installed at the air outlet 27 of the indoor unit 26. When the air conditioner indoor unit 26 operates, there will be air flow at the air outlet 27. That is, the air flow at the air outlet 27 will push the wind turbine blades 4 of the ultraviolet sterilization device 23 to rotate, so as to drive at least three surfaces and the LED light sources 1 on at least three surfaces to rotate around the rotation axis 3 through the wind turbine blades 4.

[0068] Figure 7 In the structure shown, since the wind turbine blades 4 drive the LED light sources 1 to rotate around the rotation axis 3, there is no need to install a rotation motor 5, which is more energy-saving and environmentally friendly. Figure 8 In the structure shown, the conductive component 6 is connected to one side of the rotation axis 3, and the conductive component 6 is electrically connected to the power supply of the air conditioner unit, so as to supply power to the LED substrate through the power supply inside the air conditioner unit and drive the LED lamp beads to emit light.

[0069] In some other embodiments of the present invention, the ultraviolet sterilization device can also be installed at the air outlet of the air conditioner unit, such as at the air outlet of the air conditioner indoor unit or the air outlet of the central air conditioner, as Figure 9 and Figure 3 As shown, the ultraviolet sterilization device 23 is installed at the air outlet 27 of the indoor unit 26. When the air conditioner indoor unit 26 operates, the rotation motor 5 of the ultraviolet sterilization device 23 drives the rotation axis 3 to rotate, so as to drive at least three surfaces and the LED light sources 1 on at least three surfaces to rotate around the rotation axis 3.

[0070] As Figure 3 shown, the conductive component 6 is connected to one side of the rotation axis 3, and the conductive component 6 is electrically connected to the power supply of the air conditioner unit, so as to supply power to the LED substrate through the power supply inside the air conditioner unit and drive the LED lamp beads to emit light. Figure 9 In the structure shown, the rotation motor 5 drives the LED light sources 1 to rotate around the rotation axis 3. Since the rotation speed of the rotation motor 5 is adjustable, the sterilization effect can be optimized by adjusting the rotation speed of the rotation motor 5.

[0071] It should be noted that Figure 9 in the structure shown, the ultraviolet sterilization device 23 can also have wind turbine blades 4, so as to drive the rotation axis 3 to rotate simultaneously through the wind turbine blades 4 and the rotation motor 5, or drive the rotation axis 3 through the wind turbine blades 4 and the rotation motor 5 respectively at different time intervals.

[0072] It should also be noted that the ultraviolet sterilization device in the embodiments of the present invention can be applied not only to air conditioner units, but also to the interiors of devices such as disinfection cabinets or disinfection drying machines.

[0073] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
