As illustrated in the drawing, the transparent grill-type pipeline module 1 of the present invention consists of a pipeline through which air flows, an inlet pipe 10 through which air is introduced, an outlet pipe 11 through which air flows out, and the inlet pipe. It has a configuration including a plurality of intermediate conduits (12) disposed between (10) and the outlet conduit (11). The inflow pipe 10, the outflow pipe 11, and the intermediate pipe 12 are all made of a pipe member made of a transparent material such as acrylic, glass, etc. through which UV-C can pass. Here, it should be understood that the material of the transparent grille type conduit module 1 is "transparent" as long as it can transmit UV-C, and does not necessarily have to be transparent to the naked eye. 1 and 2, arrows indicate the flow of air.

The inflow pipe 10 is elongated, and for convenience, the direction in which the inflow pipe 10 is extended is called a “first direction”. The arrow X-X direction in FIG. 1 corresponds to the first direction. The outflow pipe 11 also extends long, and the outflow pipe 11 also extends in the first direction like the inflow pipe 10 , but is positioned side by side with the inflow pipe 10 at a distance.

The intermediate conduit 12 is a member elongated in a state perpendicular to the inlet conduit 10 and the outlet conduit 11, and a plurality of intermediate conduits 12 are arranged in parallel with each other at an interval, the intermediate conduit 12 Both ends of each are coupled to the inlet pipe 10 and the outlet pipe 11 and communicated with each other. The direction in which the intermediate conduit 12 extends is called a “second direction”, and the arrow Y-Y direction in FIG. 1 corresponds to the second direction. For reference, the arrow Z-Z direction of FIG. 1 orthogonal to both the first direction and the second direction, that is, the thickness direction of the transparent grill-type conduit module 1 according to the present invention is called a “third direction”. In the transparent grill-type conduit module 1 of the present invention, as above, a plurality of intermediate conduits 12 are positioned side by side at a distance from each other, and both ends of the intermediate conduit 12 have an inlet conduit 10 and an outlet conduit 11, respectively. ), the expression "grill type" was used because it has a shape that is connected and connected.

In the transparent grill-type conduit module 1 according to the present invention, the air introduced through the inlet flows into each intermediate conduit 12 while passing the inlet conduit 10, and the air that has passed through each intermediate conduit 12 After being merged in the outlet pipe 11, an air flow path is formed that flows along the outlet pipe 11 and goes out to the outlet.

3 is a schematic perspective view showing a state in which a UV-C lamp is installed in order to irradiate UV-C to the transparent grill-type pipeline module 1 of FIG. 1 . 4 is a schematic side view viewed in the direction of the arrow K of FIG. 3 is shown. For convenience, in the drawings, the UV-C lamp is shown in the form of a cylindrical rod member. In particular, in the drawings, a plurality of UV-C lamps are shown in a form in which a plurality of UV-C lamps are intermittently arranged in a row in the extending direction, but UV-C lamps extended long according to the length of the pipe may be used, and a grill-type pipe module The number of UV-C lamps installed in the vicinity of (1) is not limited to those illustrated in the drawings and may be further increased or decreased as necessary.

The present invention is provided with a UV-C lamp for irradiating by emitting UV-C to the air flowing along the transparent grill-type pipeline module (1). In particular, in the present invention, in order to continuously irradiate UV-C to the air while the air flows along the transparent grill-type pipeline module (1), a UV-C lamp is installed on the outside of the entire transparent grill-type pipeline module (1). can be provided. Specifically, a UV-C lamp is disposed on the outside of each of the inlet pipe 10 and the outlet pipe 11 , and the rod-shaped first UV-C lamp 21 elongated in the first direction is introduced as illustrated in the drawing. The conduit 10 and the outlet conduit 11 are respectively disposed in parallel and spaced apart from each other. Therefore, while the air passes through the inlet pipe 10 and the outlet pipe 11, respectively, UV-C is continuously irradiated by the first UV-C lamp 21 to sterilize the air. If necessary, a UV-C lamp may be provided inside the transparent grill-type conduit module 1 .

In addition, UV-C lamps are respectively disposed in the interval existing between the outside of the intermediate pipe 12 and the intermediate pipe 12 to illuminate the UV-C to the intermediate pipe 12 as well. For convenience, a UV-C lamp disposed in parallel with the intermediate pipe 12 and irradiating UV-C to the intermediate pipe 12 is called a “second UV-C lamp 22”. The second UV-C lamp 22 is also composed of a rod-shaped lamp elongated in the second direction as illustrated in the drawing and may be arranged in parallel with the intermediate pipe 12 in a spaced apart state. Therefore, UV-C is continuously irradiated to the air by the second UV-C lamp 22 to sterilize even while the air flows from the inlet pipe 10 to the intermediate pipe 12 and flows through the intermediate pipe 12 . this is done

As described above, in the transparent grill-type pipeline module 1 according to the present invention, a plurality of intermediate pipelines 12 are provided between the inlet and outlet pipelines in the process in which the introduced air flows to the outlet pipeline 11 through the inlet pipeline 10 . ), but it has a configuration in which air is continuously exposed to UV-C by the light emission of UV-C lamps around each pipe in the process of air flowing. In particular, in the transparent grill-type conduit module 1 of the present invention, a long air flow path is formed in the order of an inlet pipe, an intermediate pipe, and an outlet pipe, and the inlet pipe 10 and the outlet pipe 11 are parallel to the outside. The first UV-C lamp 21 is provided, and in addition to this, the second UV-C lamp 22 is also provided in the space between the outside of the intermediate pipe 12, so that the air flows along the long air flow path. UV-C is continuously irradiated to the air over the air passage. That is, UV-C is irradiated throughout the long air passage while having the longest air passage in a small space. Therefore, the time the air flows through the pipeline, that is, the residence time of the air becomes longer, and UV-C irradiation is made throughout the extended residence time, and accordingly, the amount of UV-C light irradiation to the air increases, so that the It has the advantage of maximizing the air sterilization effect.

On the other hand, the transparent grill-type conduit module 1 according to the present invention having the above configuration may be used in a form in which a plurality of them are stacked in close contact with each other in the third direction. 5 is a schematic perspective view showing a state in which a plurality of transparent grill-type pipeline modules are stacked in close contact with each other in a third direction. For convenience, the illustration of the UV-C lamp is omitted in FIG. 5 , and three transparent grill-type conduit modules in close contact in the third direction are labeled with reference numbers 1-1, 1-2, and 1-3, respectively.

As illustrated in FIG. 5 , in the present invention, a plurality of transparent grill-type conduit modules can be integrally laminated and combined so that the third-direction side surfaces of the transparent grill-type conduit module are in close contact with each other. bonding can be made. Therefore, if a large air volume (the amount of air that has passed through the sterilizer) is required, an appropriate number of transparent grill-type conduit modules can be used by closely stacking them as illustrated in FIG. , the advantage of being able to respond quickly, easily, and very appropriately and effectively to the required air volume is also exhibited. That is, if necessary, by stacking and using a plurality of transparent grill-type conduit modules, it can be made to have sufficient air volume as required.

On the other hand, in closely stacking a plurality of transparent grill-type pipeline modules in the third direction as described above, by making the air inflow-outflow directions of the transparent grill-type pipeline modules closely stacked adjacent to each other opposite to each other, in each direction UV-C sterilization is performed for all flowing air, and energy can be saved by heat exchange at the same time.

6 and 7, each of the two transparent grill-type conduit modules is located in a mirror-symmetrical relationship with each other about the axis in the second direction, and the side surfaces of the third direction are arranged so as to be in close contact with each other. A schematic perspective view showing is shown. FIG. 8 is a schematic perspective view showing an additional UV-C lamp in the configuration of FIGS. 6 and 7 , and FIG. 9 is a schematic side view viewed in the direction of arrow J of FIG. 8 . In FIGS. 5 to 9, the two transparent grill-type pipeline modules closely arranged in a mirror-symmetrical relationship are referred to as a first-side transparent grill-type pipeline module (1a) and a second-side transparent grill-type pipeline module (1b), respectively. 6 to 8, arrows indicate the flow of air.

As illustrated in FIGS. 6 to 9 , when the first side and the second side transparent grill-type conduit module 1a, 1b are combined, the first-side transparent grill-type conduit module 1a moves the outside air into the room. The function of introducing and the second side transparent grill-type conduit module 1b may each have a function of discharging indoor air to the outside. In this case, the outside air can be sterilized and introduced into the room, and the inside air can be sterilized and discharged to the outside. Therefore, the transparent grill conduit module illustrated in FIGS. 6 to 9 can be very usefully used in treatment facilities related to infectious diseases that require sterilization of indoor air when external air is introduced into the room and exhausted at the same time.

In particular, in the above configuration, since the first side and the second side transparent grill type pipe module (1a, 1b) are in close contact with each other, each of the first side and the second side transparent grill type pipe module (1a, 1b) In the process of air flowing, heat exchange occurs with each other. As exemplified above, in the process in which outside air is introduced into the room through the first side transparent grill type conduit module 1a, and the air inside the room is discharged to the outside through the second side transparent grill type conduit module 1b, The heat exchange between the indoor air and the outside air is achieved by the close contact of the first and second side transparent grill-type conduit modules 1a and 1b. Therefore, the effect of suppressing the energy loss due to ventilation as much as possible is exhibited.

On the other hand, when installing the transparent grill-type conduit modules overlapping each other while being positioned in a mirror-symmetric relationship with each other, two or more may be arranged so as to be in close contact with each other. 10 is a schematic view showing a configuration in which four transparent grill-type conduit modules are placed in a mirror-symmetrical relationship with each other and arranged so that the side surfaces in the third direction are placed in close contact with each other in a state in which they are positioned in a mirror-symmetrical relationship with each other about the axis in the second direction. A perspective view is shown, and FIG. 11 is a schematic plan view of the embodiment shown in FIG. 10 . 10 and 11, the configuration described above with reference to FIGS. 6 to 9, that is, the first side and the second side transparent grill-type conduit module are in close contact with the side surfaces in the third direction, It has a configuration that is repeated in the third direction. In the form of the embodiment shown in FIGS. 10 and 11 , the effect of further expanding heat exchange with each other in the process of air flowing to each of the first side and the second side transparent grill-type conduit module is exhibited. As such, the number of transparent grill-type conduit modules to be installed while being positioned in a mirror-symmetrical relationship with each other is not limited to those illustrated in the drawings, and may be increased or decreased as necessary.

The transparent grill-type conduit module according to the present invention may be disposed in the case member 3 . Fig. 12 is a schematic perspective perspective view showing a state in which the transparent grill-type conduit module and the UV-C lamp having a heat exchange function illustrated in Fig. 7 are disposed in the case member 3, and Fig. 13 is an arrow in Fig. 12 A schematic cross-sectional view in the second direction along PP is shown.

As illustrated in FIGS. 12 and 13 , the transparent grill-type conduit module is built into the case member 3 . Although the UV-C lamp is also built into the case member 3 , the illustration of the UV-C lamp is omitted in FIGS. 12 and 13 for convenience. That is, although not shown in the drawings, the UV-C lamp is positioned at a predetermined position and spaced apart from the outer surface of the transparent grill-type conduit module by a protruding support rod or the like inside the case member 3 . In the present invention, the inner wall of the case member 3 is made of a reflective wall capable of reflecting UV-C, and a portion of the reflective wall facing the intermediate conduit 12 is curved so as to surround the intermediate conduit 12 . can be made in the form

14 is a schematic enlarged view of the circle C portion of FIG. 13 , and as illustrated in FIG. 14 , on the reflective wall of the case member 3, further toward between the intermediate conduits 12 as illustrated in the drawing A protruding curved protrusion 31 may be present, and a curved concave portion 32 may be present in a portion surrounding the intermediate conduit 12 existing outside. When the curved protrusion 31 and the curved concave portion 32 are provided, UV-C emitted from the second UV-C lamp 22 disposed to extend in the second direction is indicated by the letter L in FIG. 14 . UV on the intermediate pipe by being reflected and irradiated in the direction of the intermediate pipe 12 by the shape of the curved protrusion 31 and the curved concave part 32 while colliding with the curved protrusion 31 and the curved concave part 32 as shown by the arrow -C The amount of light irradiation is maximized. Therefore, the UV-C emitted from the UV-C lamp is not wasted and is effectively used for air sterilization.

15 is a schematic enlarged view of the circle E of FIG. 13 . As illustrated in FIG. 15 , the reflective wall of the case member 3 may be formed in a curved shape, as described with reference to FIG. 14 . UV-C emitted from the second UV-C lamp 22 arranged to extend in the second direction is reflected and irradiated in the direction of the intermediate pipe 12 after hitting the curved reflective wall of the case member 3, Accordingly, the amount of UV-C light irradiation to the intermediate pipe is maximized and the UV-C emitted from the UV-C lamp is effectively used for air sterilization.

As seen above, in the UV-C air sterilizer according to the present invention, the length of the air passage through which the air flows is maximized, so that the residence time becomes longer. Since the amount of UV-C light irradiation in the air passage is increased by being irradiated, it has the advantage of maximizing the air sterilization effect by UV-C.

In addition, the UV-C air sterilizer according to the present invention has a configuration that can easily increase the amount of air that has passed through the sterilizer as needed, so that it is possible to respond very easily to the required air volume.

Furthermore, the UV-C air sterilizer according to the present invention may have a configuration in which air does not flow in only one direction, but in opposite directions, at the same time, so that heat exchange occurs when air flows in both sides By doing so, the effect of minimizing heat energy loss is exhibited. The UV-C air sterilization device of the present invention can be easily applied to various places where air sterilization is required, and in particular, it can be very usefully used in infectious disease management facilities such as a ward dedicated to infectious diseases.
