Below, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. In order to clearly explain the present invention in the drawings, parts that are not related to the description are omitted, and similar parts are given similar reference numerals throughout the specification.

Throughout the specification, when a part is said to “include” a certain component, this means that it may further include other components rather than excluding other components, unless specifically stated to the contrary.

Figure 1 is a perspective view showing the overall shape of an air sterilization reactor according to an embodiment of the present invention. As shown in FIG. 1, the air sterilization reactor according to one embodiment of the present invention has an overall cylindrical shape, and is formed with an air inlet 11 on one side and an air outlet 12 on the other side. The air sterilization reactor may be made of plastic material, metal material, etc. The air inlet 11 and the air outlet 12 are narrower than the main body 10 of the reactor, and one of the inlet 11 and the outlet 12 has a fan 70 for introducing air into the main body 10. ) can be formed.

Hereinafter, the structure of the air sterilization reactor will be described in more detail with reference to FIGS. 2 and 3.

Figure 2 is a cross-sectional view of a first example of an air sterilization reactor according to an embodiment of the present invention. As shown in Figure 1, the air sterilizing reactor according to the present invention may be composed of a main body 10, a reflective coating surface 20, a sphere 30, a first sterilizing light source 40, and a fan 70. there is.

As described above, the main body 10 may be composed of an air inlet 11, an air outlet 12, and a hollow portion 13. Here, a fan 70 may be installed in the air inlet 11 or the air outlet 12 to introduce external air into the hollow portion inside the main body 10. And the hollow part 13 becomes a space where sterilization of incoming air is performed.

A reflective coating surface 20 is applied to the inner surface of the main body 10. An aluminum-coated surface may be used as the reflective coating surface 20. The reflective coating surface 20 functions to increase the sterilizing light irradiation area for incoming air by reflecting the sterilizing light emitted from the first sterilizing light source 40 installed on the sphere 30 multiple times.

A sphere 30 is formed in the center of the hollow part 13, and a first sterilizing light source 40 is installed in the sphere 30. The sphere 30 occupies a significant portion of the hollow part and functions to impede the flow of incoming air, allowing the incoming air to stay in the hollow part 13 for a longer period of time. The surface of the sphere 30 is coated with a reflective coating surface 20.

A first sterilizing light source 40 is installed in the sphere 30, and the first sterilizing light source 40 may include a randomly installed sub-sterilizing light source 41. With this configuration, the sterilizing light emitted from the first sterilizing light source 40 is irradiated in all directions of the reactor. The irradiated sterilizing light is reflected by the reflective coating surface 20 applied to the inner surface of the main body 10, The reflected irradiated light is re-reflected by the reflective coating surface of the sphere 30 or another reflective coating surface 20 on the inner surface of the main building. This re-reflection phenomenon is repeated, and due to this re-reflection repetition, the amount of sterilizing light irradiated to the incoming air increases. Accordingly, the sterilization efficiency for outdoor air increases.

Hereinafter, a second embodiment of the air sterilization reactor according to the present invention will be described with reference to FIG. 3.

Figure 3 is a cross-sectional view of a second embodiment of the air sterilization reactor according to an embodiment of the present invention. Unlike the example of FIG. 2, FIG. 3 includes a partition wall 50 installed on the inner surface of the hollow part 13 in a zigzag pattern instead of a sphere 30, and a second sterilizing light source 60 installed at each partition wall 50. there is. The partition walls 50, which are installed in a zigzag manner, are installed to overlap each other to form a zigzag flow path for external air, thereby allowing the incoming air to stay in the hollow portion 13 for a longer period of time. And the partition wall 50 may also be coated with a reflective coating surface 20. And a second sterilizing light source 60 is installed on the upper or lower surface of the partition wall 50. The sterilizing light radiated from the second sterilizing light source 60 is re-reflected by the reflective coating surface 20 of the opposite partition 50 or another reflective coating surface 20 on the inner surface of the main body 10. This re-reflection phenomenon is repeated, and due to this re-reflection repetition, the amount of sterilizing light irradiated to the incoming air increases. Accordingly, the sterilization efficiency for outdoor air increases.

Meanwhile, although not shown, the sphere 30 of the first embodiment may be installed in the central part of the hollow portion, and a partition wall 50 may be installed in other spaces. In this case, the sterilization efficiency increases as the air flow is further slowed and the outside air stays in the hollow part longer, and the re-reflection phenomenon becomes more diverse, which can further increase the sterilization efficiency.

Figure 4 is a diagram for explaining a reactor assembly in which a plurality of air sterilization reactors are assembled, which is an embodiment of the present invention. A plurality of air sterilization reactors according to an embodiment of the present invention described in FIGS. 1 to 3 can be assembled and used as one “sterilization device.” As shown in Figure 4, a plurality of holes are formed in the upper and lower plates, and the air sterilization reactor according to the present invention is placed side by side in the holes. And pillars are installed at the corners of the upper and lower plates. By configuring in this way, an air sterilization device consisting of “multiple air sterilization reactors” can be constructed in the form of one assembly.

The air sterilization reactor described above cannot be applied limited to the configuration and method of the above-described embodiments, but the embodiments are configured by selectively combining all or part of each embodiment so that various modifications can be made. It can be.
