In the sterilization device 10 according to the present invention, even the light source 300 coupled to the light source coupler may be included as components of the present invention. The light source 300 is a device that is coupled to the light source coupler and emits light for sterilization. As the light source 300, any device may be used as long as it is a device that emits light for sterilization. However, it is preferably made of a UV irradiation unit composed of a UV quartz tube or a UV lamp for irradiating UV as a light source 300 for sterilization. More preferably, it is good to use a UV lamp that irradiates UVC (220 ~ 280nm) or UVV (170 ~ 220nm) among ultraviolet rays, and it is most preferable to use a UV irradiation unit that irradiates UVC.

UV (ultra violet) refers to ultraviolet rays and has a wavelength range (750 Thz) of 10 nm to 400 nm, which is a region that cannot be seen with the human eye, adjacent to the violet band in the electromagnetic spectrum. These UV rays can cause substances to cause chemical reactions to emit light or to generate a fluorescence effect. Therefore, ultraviolet rays not only simply heat living organisms, but also cause interactions of molecules in the body. Using this point, it is possible to perform sterilization by adopting a method of destroying DNA using a UV wavelength of a certain wavelength.

However, even the UV wavelength does not perform the sterilization function in all ranges. In general, UV wavelength is a wavelength cycle, and the names are divided by wavelength, such as UVA, UVB, and UVC, and there are differences in sterilization power.

Among these UV wavelengths, UVC has the highest sterilization power, and since it is a method of sterilization by destroying DNA, the time required for sterilization is relatively short compared to other wavelengths. However, since it is basically a method of destroying DNA, it should be used with caution because it can cause harmful elements to humans.

In addition, the number of light sources 300 may be provided in various ways according to usage conditions. In the case of the first structure of the above-described structure of the housing 100, it is preferable to have one or more on one side of the center of the housing 100, and in the case of the second structure, as shown in FIG. 5, each dividing surface 133 It may be provided in one or a plurality of parts according to the usage mode, and the same number or different numbers may be provided for each split surface 133, or different types of light sources for irradiating different wavelengths may be provided. In addition, the light source 300 may be provided in at least one of the housing 100 and the side housing 200 . For smooth sterilization, it is preferable to be provided in both the housing 100 and the side housing 200, but depending on the usage mode, only one light source 300 is provided and the other one is provided with only a reflector to be irradiated by the light source 300. An irradiation angle of light may be changed by reflecting light through a reflector.

The placement confirmation unit 400 is provided on one side of the housing 100 and is a device that allows a user to visually check the range in which sterilization is performed by the light emitted from the light source 300 . In general, ultraviolet rays are an area outside the range of visible light that can be visually confirmed by humans, and it is difficult for users to visually check the irradiation range. is impossible to ascertain. Accordingly, the shadow generation area according to the irradiation range of the light source 300, the area (L), and the arrangement of furniture inside the sterilization area (A) through the placement confirmation unit 400 that irradiates visible light that can be visually confirmed by the user. (S) etc. can be visually confirmed. Through this, it is possible to adjust the arrangement position of the sterilization device 10 optimized for sterilization in the sterilization area A, the number of installations, the arrangement angle of the side housing 200, and the like. The placement confirmation unit 400 may be provided in various positions and numbers on one side of the housing 100 and the side housing 200 in consideration of the irradiation direction and length of the light emitted from the light source 300 . Although the present invention focuses on the provision of a plurality of arrangement confirmation units 400, this is only one embodiment and the number and arrangement position thereof may be configured in various ways according to the usage mode.

The placement confirmation unit 400 may use any device as long as it can irradiate visible light having an irradiation length and an area L corresponding to the UV irradiated from the light source 300 . However, it is preferable to use an LED irradiation unit having an irradiation length, an area L, and the like corresponding to that of the light source 300 emitted from the light source 300 . In addition, the placement confirmation unit 400 is preferably provided at a location that does not interfere with the irradiation of light emitted from the light source 300, and accordingly, it can be installed in various locations in consideration of the location of the light source 300.

In addition, depending on the usage mode, the arrangement confirmation unit 400 is provided in a detachable type rather than a fixed type, and is removed after confirming the arrangement of the sterilization device 10, which may interfere with the irradiation of light emitted from the light source 300. The irradiation efficiency of the light source 300 may be maximized by completely removing the .

When UV, in particular, UVC is used as the light source 300 in the sterilization device 10 according to the present invention, when the light source 300 is irradiated to a person or animal, it may cause damage to the skin, eyes, etc. Sensor unit Reference numeral 500 is a device that recognizes the approach of a person or animal and transmits a signal to the control unit 600 to cut off power supplied to the light source 300 to stop irradiation of the light source 300 . As such, the sensor unit 500 may use any sensor as long as it is a device capable of detecting the approach of a person or animal and transmitting a signal to the control unit 600 . In one embodiment, the sensor unit 500 may use a motion detection sensor. In addition, the sensor unit 500 may use at least one of various types of sensors in anticipation of various risk factors that may occur during sterilization in addition to detecting the approach of a person or animal.

The control unit 600 is provided on one side of the housing 100 and controls power supplied to the light source 300 to control whether the light source 300 is irradiated, irradiation time, irradiation intensity, and the like. The controller 600 is preferably provided on one side of the housing 100, preferably at the lower end of the housing 100 to serve as the center of gravity of the sterilization device 10, and can control the light source 300. Any device may be used as long as it is a device. At this time, the controller 600 is a timer for controlling the irradiation time of the light source 300, a controller 600 of an adjacent sterilization device 10 or a transceiver that can be connected to a user terminal by wire or wirelessly, and is exposed to the outside to the user. may further include a control unit such as a touch panel capable of inputting a control signal. In addition, one side of the controller 600 may further include a coupling device (not shown) for facilitating movement and storage by combining the plurality of sterilization devices 10 when moving or storing the plurality of sterilization devices 10. there is.

Sterilization method using a sterilizer

A sterilization method of sterilizing the sterilization area A by utilizing the sterilization device 10 having the above configuration will be described in more detail.

First of all, if a preparation process for performing sterilization is required after confirming the surrounding environment of the sterilization area A, a pretreatment process may be performed. The sterilization device 10 used in the present invention sterilizes using a UV light source as a light source 300. Among the UV light sources, a UV light source in the UVC wavelength range having high sterilization properties is used, which, as described above, may cause harmful effects to the human body when directly irradiated to the human body. Accordingly, in order to prevent the light source 300 from being irradiated to the outside of the sterilization area A while sterilization is being performed in the sterilization area A, a blocking member such as a blackout curtain is installed on a window through which the light source 300 can pass. Take measures to protect users and administrators by installing or installing access prevention notices to prevent human access. Existing devices had to arrange furniture to minimize the area S where sterilization is not performed due to shadows caused by desks, etc., but the sterilization device 10 according to the present invention utilizes the side housing 200 to Since the area S can be minimized, movement of furniture, etc., can be minimized to maximize convenience for users and managers.

10 is a flowchart sequentially showing a sterilization method using a sterilization device according to the present invention. Next, the light irradiation area according to the area, shape, arrangement of internal furniture, etc. of the sterilization area A, the light irradiation range and irradiation length of the light source 300 of the sterilization area A and the light source 300 of the sterilization device 10 ( L) and the like are comprehensively placed to dispose the sterilization device 10 inside the sterilization area A (S100). At this time, since the ultraviolet ray emitted from the light source 300 irradiates light in an area that is not visible to the human eye, check the arrangement of irradiating visible light corresponding to the irradiation area (L) and length of the light emitted from the light source 300. Using the unit 400, the user can check the optimal arrangement position with the naked eye. A method for setting the angle of the side housing 200 for the arrangement of the sterilization device 10 will be described through several embodiments.

First, as shown in FIG. 2 or 6, the light source 300 provided on at least one of the housing 100 and the side housing 200 by opening the side housing 200 provided on at least one side. It allows light to be irradiated to the outside. At this time, it is preferable that the side housing 200 is basically opened at least 90 degrees.

8 is a side view showing an elevated state of the housing according to the present invention. Next, when the floor height of the building is high, as shown in FIGS. 1, 3 and 4, the internal support 122 or the internal frame 132 is raised, or as shown in FIG. 8, the controller ( 600) and the lower housing 100 as a whole to raise the position of the light source 300 as a whole, so that it can be applied to buildings with high floor heights. In addition, when a lifting unit is further provided between the control unit 600 and the lower panel 110 of the housing 100, the housing 100 can be applied to a high floor height by lifting the entire height of the housing 100. As such, when the light source 300 does not reach a sufficient irradiation height even when the housing 100 is raised, the light may be irradiated to a higher height than when the side housing 200 is vertically opened. That is, the sterilization area A having a floor height up to twice as high as the height of the housing 100 can be sufficiently sterilized according to the elevation of the housing 100 and the opening angle of the side housing 200.

In addition, the side housing 200 provided on the upper part of the housing 100 adjusts its placement position and angle according to the upper surface of a shelf, closet, etc., as well as the height of the floor, and the side housing provided on the lower side ( 200) can freely adjust and fix the arrangement angle in order to sterilize the lower surface of the desk.

9 is a side view showing angle adjustment and rotation of the side housing according to the present invention. In addition, when the side housing 200 is coupled to one side of the housing 100 through a ball joint or a universal joint, when there is a gap between a wall and furniture, a gap caused by a pillar 1000, etc. As such, sterilization can be performed smoothly by rotating one of the side housings 200 to change the irradiation direction of the light source 300 .

As described above, when the sterilization device 10 is disposed, the sterilization device 10 is disposed through the placement confirmation unit 400 provided in at least one of the housing 100, the control unit 600, and the side housing 200. Since the number of batches, the batch position, and the arrangement angle of the side housing 200 can be visually checked and placed, it is possible to clearly check the area where the light emitted from the light source 300 is not irradiated, thereby minimizing the sterilization blind spot. . Accordingly, the sterilization efficiency of the sterilization area A can be maximized. In this way, reliability of sterilization can be improved because the light irradiation range and the shadow generation area (S) are confirmed through the visually confirmable placement confirmation unit 400 .

When the area of the sterilization area A is small or there are few obstacles such as furniture, the sterilization device 10 according to the present invention can irradiate the 360-degree omnidirectional light source 300 through one device, so that one sterilization device ( 10) is free to use. However, when the area of the sterilization area (A) is wide or there are many obstacles such as furniture and pillars 1000 inside, it is possible to evenly sterilize the entire inside of the sterilization area (A) with only one sterilization device (10). Since it can be difficult, it is also possible to arrange a plurality of sterilization devices 10 . In the case of using a plurality of sterilization devices 10 as described above, the plurality of sterilization devices 10 are combined into one through a coupling device provided on one side of the control unit 600 or the housing 100 and capable of mutual coupling and separation, moving, and then separating the plurality of sterilization devices 10. can be arranged to maximize work efficiency.

At this time, the arrangement of the plurality of sterilization devices 10 may be set through the placement confirmation unit 400 from the initial placement process, or through the placement confirmation unit 400 after arbitrarily placing the plurality of sterilization devices 10. The position of the arrangement may be checked, and the position of the sterilization device 10 may be readjusted through this. In the case of arranging the plurality of sterilization devices 10 as described above, it is preferable to arrange the irradiated light overlapping at predetermined intervals rather than generating an area where no light is irradiated.

As such, the irradiation area (L) of the light source 300, the irradiation distance, and the presence or absence of obstacles are visually confirmed through visible light, and the arrangement, height adjustment, and opening angle of the side housing 200 of the sterilization device 10 and Since the rotation angle can be adjusted, anyone can easily set the number and position of the sterilization device 10.

11 is a schematic arrangement state diagram showing a state in which the sterilization device according to the present invention is arbitrarily arranged, and FIG. 12 is a schematic arrangement state diagram showing a state in which the sterilization device according to the present invention is arranged through a placement confirmation unit 400 . That is, when the light irradiation area L of the sterilization device 10 is simply numerically calculated and arranged, as shown in FIG. 11, the sterilization area A ) There may be a space that is not sterilized inside. In addition, even if it is included in the sterilization range of the sterilization device 10, sterilization cannot be smoothly performed in the area S where shadows are generated by obstacles such as pillars 1000 and the like. However, when the user visually arranges the sterilization device 10 through the placement confirmation unit 400, as shown in FIG. 12, the light irradiation area L of the sterilization device 10 is visually checked and placed Therefore, it can be arranged without space beyond the irradiation area L of the light emitted from the light source 300 . In addition, when an obstacle such as a pillar 1000 is disposed, as in the sterilization device 10 disposed in the middle of the left side of FIG. By irradiating light, the shadow generation area S can be minimized.

As such, the sterilization device 10 according to the present invention is configured to adjust not only the angle and height of the housing 100, but also the arrangement height, opening angle, rotation angle, etc. of the side housing 200, so there are obstacles and the like. Even in the sterilization area (A) of a complex structure, it is possible to maximize the sterilization effect by minimizing the shadow generation area (S).

Next, the verification unit 900 is attached to one side wall, floor, ceiling, furniture, and pillar 1000 of the sterilization area A (S200). The number and attachment positions of the verifying unit 900 may be selectively determined in consideration of the environment of the sterilization area A. In particular, the verification unit 900 is preferably attached to one side that is expected to be a weak sterilization area, such as an inclined surface that is not in contact with the irradiated light in a direction perpendicular to the sterilization device 10 and a position spaced as far away as possible. As the number of attached verifying units 900 increases, the reliability of the sterilization state increases, but it is preferable to selectively determine the sterilization cost because sterilization costs may increase. In addition, in the case where sufficient data such as the arrangement position of the sterilization device 10 and the arrangement angle of the side housing 200 are accumulated while repeatedly sterilizing the sterilization area A, the verification unit 900 may not be attached.

Next, the control unit 600 applies the power applied from the power supply unit to the light source 300 through the power line 800 when a signal to start irradiation of the light source 300 is applied remotely from the control unit or the outside, so that the light source 300 Light for sterilization is irradiated (S300). At this time, when a signal to start irradiation of the light source 300 is applied through a switch provided on one side of the sterilization device 10, a predetermined waiting time is set to provide time for the operator to leave the sterilization area A. After excitation, it is controlled to irradiate light. In one embodiment, the light source 300 may be irradiated from about 15 seconds after the operator operates the switch. This waiting time can be set so that the operator has enough time to leave the sterilization area (A) in consideration of the area of the sterilization area (A). In addition, when a plurality of sterilization devices 10 are disposed, each sterilization device 10 is not individually operated, and when a signal to start irradiation of the light source 300 is input to any one sterilization device 10, each sterilization device 10 It is obvious that the control unit 600 provided in the device 10 can work with each other to simultaneously irradiate the light source 300 . To this end, the control unit 600 provided in each sterilization device 10 may be set to interoperate through wired or wireless communication. Depending on the usage mode, the sterilization device 10 may be remotely controlled through a separate remote control or an operator's portable terminal.

In this way, when the sensor unit 500 detects an abnormal signal while irradiating light from the light source 300, the light irradiation of the light source 300 may be urgently stopped. As described above, since ultraviolet rays in the UVC wavelength band can have a harmful effect on the human body, when a human or animal is detected by the sensor unit 500 during the sterilization process, the sensor unit 500 sends the control unit 600 abnormally. After transmitting the signal, the controller 600 urgently cuts off the power applied to the light source 300 . At this time, when a discrete signal is detected in any one of the plurality of sterilization devices 10, the power of the light sources 300 of all interlocked sterilization devices 10 is cut off. In the present invention, the sensor unit 500 is provided with a motion sensor to sense the motion of a person or animal and generate an abnormal signal. Various sensors can be used, and it is also obvious that two or more types of sensors can be used in combination.

When an emergency stop occurs like this, the control unit 600 transmits information about the occurrence of an abnormal situation to the previously entered portable terminal of a worker or manager.

When such an emergency stop occurs, the sensor unit 500 continuously or periodically transmits a signal according to the surrounding situation to the controller 600, and the controller 600 automatically sends the light source 300 to the light source 300 if the abnormal signal is not re-input for a certain period of time. ), the irradiation of the light source 300 may be resumed by re-applying power. Depending on the usage mode, it may be set so that irradiation of the light source 300 is resumed only when a separate input signal is generated by a manager. It is obvious that such a setting method can be selectively set in consideration of the use environment.

Next, the control unit 600 measures a predetermined time through a timer included therein, and the set time ends or the irradiation of the light source 300 is terminated through a stop signal applied from the outside to complete sterilization (S400). . At this time, the measured time of the timer temporarily stops the timer in which the emergency stop occurs, and the irradiation of the light source 300 is terminated when the sum of the operation time before the emergency stop and the time after the restart after the emergency stop is the same as the previously input time. do.

Next, the sterilization state is visually confirmed by checking whether or not the test bacteria remain in the verification unit 900 attached to the inside of the sterilization area (A) (S500). The verification unit 900 is gradually reduced according to the time exposed to ultraviolet rays, which can be easily checked by the user with the naked eye. This process will be described in more detail through examples.

After attaching the verification unit 900 at a distance of about 2 m from the light source 300, checking the change of the verification unit 900 for each time period is shown in [Table 2]. At this time, [Table 1] shows the verification unit 900 smeared with yellow bacteria and white bacteria not exposed to UV.

[Table 2] confirms the sterilization status according to an embodiment through the verification unit 900, and some differences may occur in the sterilization time depending on the environment of the actual sterilization area (A). Therefore, since complete sterilization may not be achieved even if sterilization is performed for about 50 minutes, reliability of sterilization can be improved by checking the sterilization state through the verification unit 900. That is, since the user directly checks the degree of sterilization with the naked eye using the verification unit 900, rather than simply estimating the irradiation time of the light source 300 and irradiating the light source 300 only for the reference time to complete sterilization. Complete sterilization can be performed even if there is a difference in sterilization time depending on the use environment. As shown in the above [Table 2], if it is determined that the test bacteria remain upon confirmation through the verification unit 900, re-sterilization may be performed by re-irradiating the light source 300 for a predetermined time. In this case, the re-sterilization time may be variously set in consideration of the degree of remaining test bacteria confirmed by the manager through the verification unit 900. Since the re-sterilization process is the same as or similar to the aforementioned light source 300 irradiation process (S300) and verification unit 900 confirmation process (S500), a detailed description thereof will be omitted. In addition, the re-sterilization process may be performed only once, or may be repeatedly performed according to the status of the verification unit 900 confirmed after re-sterilization, and a plurality of sterilization devices 10 may be re-operated at the same time, or some sterilization devices 10 ), it is self-evident that re-sterilization can be performed by re-activation.

Additionally, when the sterilization inside the sterilization area (A) is completed, the user or manager displays the arrangement position of the sterilization device 10 inside the sterilization area (A) for repeated sterilization of the sterilization area (A), and the user terminal or The installation height of the housing 100, the opening angle of the side housing 200, the rotation angle, etc. are input to the controller 600 (S600). In this way, when repetitive sterilization is performed by recording the placement position, etc., the arrangement process of the sterilization device 10 is performed more smoothly without confirmation through the placement confirmation unit 400 by utilizing the initially registered data. can do.

In addition, when the sterilization process is completed, the plurality of sterilization devices 10 may be coupled to each other through a coupling device to be moved and stored at once. In this way, when the sterilization device 10 is moved and stored, the side housing 200 is closed to prevent the light source 300 stored inside from being exposed to the outside, thereby preventing the light source 300 from being damaged due to external impact, etc. It can be moved and stored safely. If there is no side housing 200, since the light source 300 is exposed to the outside, if a direct impact occurs to the light source 300 during movement and storage, the light source 300 may be damaged, so the light source 300 is sterilized. Although there are cumbersome problems such as removing from the device 10 and storing it separately, the sterilization device 10 according to the present invention is safe because the side housing 200 can prevent external shock from being transmitted to the light source 300. Can be moved and stored.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, the above-described embodiments should be understood as illustrative in all respects and not limiting.
