Description

Sterilization Device and Sterilization System Using the Same

The present invention relates to a sterilization apparatus and a sterilization method using the same, and more particularly, to a sterilization apparatus for sterilizing a sterilization space using a light source such as UV. It relates to a sterilization apparatus capable of sterilizing a sterilization space without gaps by easily setting a sterilization apparatus and a sterilization method using the same.

In general, ultraviolet sterilizers are widely known sterilizers that sterilize various pathogenic microorganisms present in the air by irradiating the moving air with ultraviolet rays while forcibly moving indoor air by a fan to a certain crotch area in which a plurality of ultraviolet lamps are installed.

However, these pathogenic microorganisms are not only contained in the air, but also exist on the surfaces of furniture, household goods, etc. provided in a sterile space. In this case, there is a problem in that sufficient sterilization cannot be achieved only with the conventional sterilization apparatus that sterilizes by sucking air.

In particular, recently, the importance of sterilization is expanding through the corona virus (COVID-19). Since these corona viruses are transmitted through droplets such as saliva of an infected person, the virus survives not only in the air but also in the surrounding household items. In order to completely sterilize these viruses, sterilization through air sterilization is also required, but there is a problem that sufficient sterilization cannot be achieved only by sterilization of air.

For this purpose, recently, a method of sterilizing the entire sterilization space using sterilization devices using sterilization liquid or sterilization steam is widely used, but this takes a long time to sterilize, and there is a problem in that use is restricted in a space where contact with moisture, etc. is impossible There is this.

As shown in FIGS. 1 to 4, the sterilization apparatus 10 is largely a housing 100, a light source irradiation unit 200, a control unit 400, a placement confirmation unit 300, a sensor unit 500, a support unit ( 600 ), a moving unit 700 , and a verification unit 900 .

The housing 100 provides a space in which the light source irradiation unit 200, the control unit 400, the arrangement confirmation unit 300, the sensor unit 500, etc. are seated, and the light source irradiated from the light source irradiation unit 200 is provided in a variety of ways, max.

The length of the main frame 110 may be made in various lengths in consideration of the length of the light source irradiator 200 to be installed, the installation environment, and the like. In one embodiment, the length of the main frame 110 forming the center of the housing 100 may have a length of about 1,000 mm to 1,500 mm.

The dividing surface 120 is formed to protrude along the longitudinal direction of the main frame 110 to divide the housing 100 into a plurality of surfaces, and to protect the light source irradiator 200 such as a UV lamp or UV quartz tube provided therein. will do The divided surface 120 is provided in various numbers in consideration of the number of installation of the light source irradiation unit 200 used for sterilization, the use environment, etc., so that the number of the divided surfaces 120 can be set. In the present invention, in one embodiment, the housing 100 can be divided into four surfaces by having four divided surfaces 120 , but it is provided with two or more divided surfaces 120 depending on the usage mode to provide two or more surfaces. The housing 100 can be divided into In addition, the dividing surface 120 may be provided entirely along the longitudinal direction of the main frame 110, or may be partially provided on one side of the main frame 110 for installation of a reflective unit 130 such as a reflector to be described later. . In addition, the divided surface 120 may be provided radially based on the longitudinal center of the main frame 110, and a plurality of divided surfaces 120 to be installed are preferably provided at equal intervals, but depending on the usage It is obvious that they may be disposed at different intervals from each other.

The reflection unit 130 is provided on one side of the housing 100, preferably on one side of the main frame 110, and more preferably on one side of the dividing surface 120 to direct the light source irradiated into the housing 100 in an external direction. It is a device for improving the light irradiation efficiency of the light source irradiator 200 by reflecting it. The reflection unit 130 is formed in a flat plate shape having a curved or bent shape in a shape corresponding to the inner space of the housing 100 according to the structure of the main frame 110 and the dividing surface 120 . It is self-evident that the reflection unit 130 may be provided as a whole along the main frame 110 and the dividing surface 120, or may be provided partially depending on the usage.

The light source coupling unit (not shown) is provided on one side of the housing 100 and is a device for coupling the light source irradiator 200 . Such a light source coupling part may use any device as long as it can be stably coupled to a UV irradiation unit made of a UV quartz tube or UV lamp in one embodiment. The light source coupling unit may have various structures depending on the shape of the UV irradiation unit, and it is preferable to use a coupling device commonly used for coupling the lighting device.

The housing 100 according to the above configuration is illustrated and described as having a longitudinal direction in the vertical direction, but depending on the usage, a separate support or a combination body is used on one side of the housing 100 in a direction parallel to the ground. It is self-evident that it can have a longitudinal direction as In addition, the housing 100 may be provided so that the installation angle can be changed according to the usage aspect. To this end, an angle adjusting unit is provided on one side of the housing 100 , preferably on one side of the lower end, so that the housing 100 can be installed by adjusting the angle to be inclined at a predetermined angle from the ground in consideration of the installation environment.

The light source irradiator 200 is a device for irradiating a light source for sterilization by being coupled to a light source coupling provided on one side of the housing 100 . As the light source irradiator 200, any device may be used as long as it is a device for irradiating light for sterilization. However, it is preferably made of a UV irradiation unit consisting of a UV quartz tube or UV lamp that irradiates UV as a light source for sterilization. More preferably, it is preferable to use a UV lamp for irradiating UVC (220 to 280 nm) or UVV (170 to 220 nm) of ultraviolet rays, and it is most preferable to use a UV irradiation unit for irradiating UVC.

UV (ultra Violet) refers to ultraviolet light, and has a wavelength region (750 THz) of 10 nm to 400 nm, which is adjacent to the violet band in the electromagnetic wave spectrum, and is invisible to the human eye. These UVs can cause substances to react chemically to emit light or produce a fluorescence effect. Therefore, ultraviolet rays not only 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 name is divided by wavelength such as UVA, UVB, and UVC, and there is a difference in sterilization power.

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

The arrangement confirmation unit 300 is provided on one side of the housing 100 to allow the user to visually confirm the range of sterilization by the light source irradiated from the light source irradiation unit 200 . In general, it is difficult for a user to substantially confirm the sterilization range of the light source irradiator 200 that substantially irradiates UV as an area outside the range of visible light that can be visually confirmed by a person. For this purpose, the user can visually check the sterilization range and area (L) through the light source irradiator 200 through the arrangement confirmation unit 300 that irradiates visible light that the user can visually confirm, and through this, efficient sterilization The arrangement position and number of arrangement of the device 10 may be set. In the drawings of the present invention, the arrangement confirmation unit 300 is provided on each divided surface 120 in three rows along the longitudinal direction of the housing 100 to be spaced apart from each other at regular intervals, but this is only an example. The arrangement position and number of the arrangement confirmation unit 300 are not limited. Depending on the usage aspect, one arrangement confirmation unit 300 is installed on each divided surface 120 or provided only in one row, etc. This may be variously changed depending on the type of the light source irradiating unit 200, arrangement conditions, etc. It is self-evident that it can

The light source irradiation area (L) used in the present invention means a distance at which sterilization can be smoothly performed by the light source irradiated through the light source irradiation unit 200, not simply the maximum length to which the light source is irradiated.

This arrangement confirmation unit 300 is preferably provided on one side of the housing 100, preferably on one side of the housing 100 provided with the light source irradiator 200, more preferably on one side of the reflective plate. Any device may be used as the arrangement confirmation unit 300 as long as it is a device capable of irradiating visible light having an irradiation length, area L, etc. corresponding to UV irradiated from the light source irradiation unit 200 . However, it is preferable to use an LED irradiation unit having an irradiation length, an area (L), etc. corresponding to the light source irradiated from the light source irradiation unit 200 . In addition, the arrangement confirmation unit 300 is preferably provided so as not to interfere with the irradiation of the light source irradiated from the light source irradiator 200 , and may be installed in various positions depending on the arrangement shape of the light source irradiator 200 . In addition, depending on the usage, it is provided on one side of the housing 100 in a removable type, not a fixed type, and after confirming the arrangement of the sterilization device 10, it is removed from the housing 100 and the light source irradiated from the light source irradiation unit 200 is irradiated. It is possible to maximize the irradiance efficiency of the light source by removing factors that may interfere with it.

At this time, the control unit 400 includes a timer for controlling the time of irradiating the light source, a transmission/reception unit connectable with the control unit 400 or the user terminal of the adjacent sterilization apparatus 10 by wire or wirelessly, and exposed to the outside to allow the user to control signals It may further include a control unit such as a touch panel capable of inputting. The control unit 400 is commonly used in an apparatus for irradiating a light source, and a detailed description thereof will be omitted.

The sensor unit 500 is provided on one side of the housing 100 or the control unit 400 to detect a person's approach while irradiating a light source, or to recognize an abnormal state occurring in the surrounding situation of the sterilization apparatus 10, and the control unit 400 It is a device that transmits In the case of using UV, particularly UVC, when such a light source is irradiated to a person or an animal, etc., it may cause damage to the skin, eye, etc., so the sensor unit 500 recognizes the approach of such a person or animal and sends it to the control unit 400 It is a device for stopping the irradiation of the light source by transmitting a signal to cut off the power supplied to the light source irradiator 200 . As such, the sensor unit 500 may use any sensor as long as it is a device capable of transmitting a signal to the control unit 400 by detecting the approach of a person or an animal. In an embodiment, the sensor unit 500 may use a motion sensor, and any device other than the motion sensor may be used as long as it is a device capable of detecting an approach of a person or the like.

The sensor unit 500 may include various types of sensors in anticipation of various risk factors that may occur during sterilization in addition to detecting people or animals.

If a plurality of sterilization devices 10 are provided, the control unit 400 provided in each sterilization device 10 is provided to interoperate with each other through wired or wireless, and is provided in any one sterilization device 10 . When an abnormality is detected in the sensor unit 500 , the control is performed to block the light sources of all sterilization devices 10 .

The support unit 600 is provided under the housing 100 to support the housing 100 so that the housing 100 can be stably disposed. The support unit 600 may be formed as a separate device as shown in the drawing, or the lower control panel 420 constituting the control unit 400 may simultaneously serve as the support unit 600 . Such a support unit 600 is a device capable of supporting the sterilization device 10 so that the housing 100 does not collapse or the installation angle is not changed and can be stably installed in the arrangement position when the sterilization device 10 is installed, no matter what device is used. free If the above-described angle adjusting unit is provided on one side of the housing 100 , the support unit 600 is preferably provided to be coupled to the angle adjusting unit of the housing 100 .

The moving unit 700 is provided at the lower end of the support unit 600 to smoothly assist the movement of the housing 100 . As the moving unit 700, it is preferable to use a commonly used moving wheel or the like.

The power supply unit (not shown) is a device connected to the control unit 400 of the sterilization apparatus 10 to supply power to the control unit 400 , the light source irradiator 200 , and the sensor. Although the present invention has been illustrated and described focusing on being connected to an outlet through the power line 800, a portable power source such as a battery may be used depending on the usage mode, and the power line 800 and a battery may be provided at the same time. It is self-evident that there may be

The sterilization device 10 having the above-described configuration is attached to one side of the sterilization space (A) and spaced apart from the sterilization device 10 at a predetermined interval according to the usage aspect, and the verification unit 900 that can confirm the sterilization state by six is more. can be provided. If the verification unit 900 is attached to the wall, floor, ceiling, or various structures of the sterilization space (A), the user can visually confirm the situation in which actual sterilization is made by the light source irradiated from the light source irradiation unit 200. It is free to use anything. One side of the verification unit 900 is provided with a removable pressure-sensitive adhesive, and the other side may include a medium for testing on which experimental bacteria such as aureus and white bacteria are smeared. In another aspect of use, the verification unit 900 may be provided to have a simple phrase in the form of a sticker. As such, the verification unit 900, which can be visually confirmed, is attached to the sterilization space (A) and sterilized for a certain time using the sterilization device 10. When the irradiation of the light source of the light source irradiation unit 200 is completed, the user is sterilized. After entering the space (A), it is possible to check the sterilization state of the sterilization space (A) through the verification unit (900). At this time, the test bacteria smeared on one surface of the verification unit 900 are sterilized as they are exposed to ultraviolet light, and the number of the test bacteria is gradually reduced. Experimental bacteria are completely sterilized. As such, by comparing the state of the test bacteria initially smeared on one surface of the verification unit 900 with the state of the verification unit 900 after sterilization is performed through the sterilization device 10, the sterilization state can be easily checked with the naked eye. Since this sterilization causes a deviation in the degree of sterilization depending on the time, angle, etc., when the light source is irradiated, the sterilization state of various locations can be easily checked with the naked eye through the verification unit 900 attached to various places in the sterilization space (A). Through this, when the sterilization is not completely made, it is possible to extend the operating time of the sterilization device 10 to perform complete sterilization.

Sterilization method using a sterilizer

A sterilization method for sterilizing the sterilization space A using the sterilization apparatus 10 having the above-described configuration will be described in more detail as follows.

5 is a process diagram showing a schematic flow of a sterilization method according to the present invention.

First, check the surrounding environment of the sterilization space (A) in which sterilization is performed, and if a preparation process for performing sterilization is required, a pretreatment process for performing this may be performed. The sterilization apparatus 10 used in the present invention sterilizes the sterilization space (A) using a light source, in particular, a UV light source. Among the UV light sources, a UV light source in a UVC wavelength band with high sterilization is used, which may cause harmful effects on the human body when directly irradiated to the human body as described above. Accordingly, in order to prevent the light source from being irradiated to the outside of the sterilization space (A) while sterilization is being performed in the sterilization space (A), the light source such as a blackout curtain is not transmitted to a part through which the light source can be transmitted, such as a window or a glass door. It can be blocked by using a blocking member that cannot. In addition, since the light source has a straightness, it may include a pretreatment process of arranging furniture, decorations, etc. that are unnecessary to be disposed inside the sterile space (A) to block the irradiation of the light source.

6 and 7 are plan views showing an embodiment in which the sterilization apparatus according to the present invention is disposed in a sterilization space. Next, the light irradiation area (L) according to the internal environment of the sterilization space (A) and the light irradiation range of the sterilization device 10, such as the area, shape, arrangement state of the interior furniture, etc. of the sterilization space (A), the irradiation length The sterilization device 10 is disposed inside the sterilization space A in consideration of the general consideration (S100). At this time, since it is difficult for the user to visually confirm the light source irradiated from the light source irradiating unit 200, the ultraviolet light has a visible area (L) and an irradiation length corresponding to the irradiation area (L) and the irradiation length of the light source irradiated with the light source. The sterilization apparatus 10 can be easily arranged using the arrangement confirmation unit 300 irradiating light. In addition, in addition to simply checking the light source irradiation area (L) of the sterilization device 10, the light source for sterilization is not irradiated by clearly checking the shadows and shadows generated by the structures and structures inside the sterilization space (A). It is possible to arrange the sterilization device 10 by minimizing the part that is not. As such, since the arrangement number and arrangement position of the sterilization apparatus 10 are set through the arrangement confirmation unit 300, even in the sterilization space A having the same area L, the arrangement diagram is the number of sterilization apparatus 10 according to the internal environment. and the location may be variously changed. However, it is possible to improve the power efficiency and sterilization reliability used during sterilization by checking the optimal number of batches and placement positions through the batch confirmation unit 300 no matter what environment is applied.

When the area (L) of the sterilization space (A) is narrow, the sterilization apparatus 10 according to the present invention is divided through a plurality of division surfaces 120, and since light source irradiation is possible in all directions 360 degrees, one sterilization apparatus ( 10) is free to use. However, when the area (L) of the sterilization space (A) is large or the internal environment is complicated, a plurality of sterilization devices (10) to sterilize the entire interior of the sterilization space (A) with only one sterilization device (10) can also be placed.

At this time, the arrangement of the sterilizer 10 may be set through the batch confirmation unit 300 from the initial arrangement process, and optionally after the sterilization device 10 is placed, the arrangement position is confirmed through the batch confirmation unit 300 . And (S110), it is possible to easily adjust the position of the sterilization apparatus 10 through this (S120). At this time, when disposing a plurality of sterilization apparatus 10, it is preferable to arrange so that the visible light irradiated from the arrangement confirmation unit 300 provided in each sterilization apparatus 10 overlaps at a predetermined interval. In this way, the number and arrangement position of the sterilization apparatus 10 disposed in the sterilization space (A) can be clearly set because the irradiation area (L) of the light source, the irradiation distance, the presence or absence of obstacles, etc. can be visually checked through the visible light. can

That is, when the light irradiation area (L) of the sterilization apparatus 10 is simply numerically calculated and arranged, a space in which sterilization is not performed may occur inside the sterilization space (A) as shown in FIG. 6 . In order to prevent this, the arrangement position of the sterilization apparatus 10 is changed or the arrangement of the sterilization apparatus 10 is checked by checking whether a space that is not sterilized by the light source occurs inside the sterilization space A through the arrangement confirmation unit 300 . By changing the number, the arrangement of the sterilization device 10 can be adjusted so that sufficient sterilization is made in all spaces of the sterilization space A as shown in FIG. 7 .

In addition, since the sterilization apparatus 10 according to the present invention is configured to be able to adjust the installation angle of the housing 100, it may be installed by adjusting the installation angle when an obstacle or the like exists.

Next, the verification unit 900 is attached to the wall, floor, ceiling, furniture, etc. of one side of the sterile space (S200). The number and attachment positions of the verification unit 900 may be selectively determined in consideration of the environment of the sterile space (A). In particular, the verification unit 900 is a slanted surface that is not in contact with the light source irradiated from the sterilization apparatus 10 in a vertical direction, a position as far from the sterilization apparatus 10 as possible, and a shadow or shadow by the internal structure of the sterilization space (A). It is recommended to attach in consideration of the side on which the lesion occurs, and the part that is in close contact with the human body or is in frequent contact with the human body. As the number of attached verification units 900 increases, the reliability of the sterilization state increases, but it is preferable to selectively determine the sterilization cost because the sterilization cost may increase.

Next, when a light source irradiation start signal is applied remotely from the control unit or the outside, the control unit 400 applies power applied from the power supply to the light source irradiation unit 200, and the light source irradiation unit 200 irradiates the light source for sterilization ( S300). At this time, when a light source irradiation start signal is applied through a switch provided on one side of the sterilization apparatus 10, the light source after having a predetermined waiting time to provide time for the operator to leave the sterilization space (A) control to be investigated. In one embodiment, the light source may be irradiated from about 15 seconds after the operator operates the switch. This waiting time can be set in consideration of the time during which the operator can sufficiently leave the sterilization space (A) in consideration of the area of the sterilization space (A). In addition, without individually controlling each sterilization apparatus 10, when a light source irradiation start signal is input through any one sterilization apparatus 10, the control unit 400 provided in each sterilization apparatus 10 interlocks. It is self-evident that the light source can be irradiated at the same time. For this purpose, the control unit 400 provided in each sterilization apparatus 10 may be set to interoperate with each other through wired or wireless. Depending on the usage aspect, the sterilization apparatus 10 may be remotely controlled through a separate remote control or a portable terminal of an operator.

When the sensor unit 500 detects an abnormal signal while the light source irradiator 200 is irradiating the light source, the light source irradiation of the light source irradiator 200 may be urgently stopped ( S310 ). As described above, since the light source of the UVC wavelength band may 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 an abnormal signal to the control unit 400 . , and the control unit 400 urgently cuts off the power applied to the light source irradiator 200 (S310). At this time, when an abnormality is detected in any one of the plurality of sterilization apparatuses 10 in the sensor unit 500 , the control unit 400 of the corresponding sterilization apparatus 10 transmits an abnormal signal to the control unit provided in the surrounding sterilization apparatus 10 . It is transferred to 400 to urgently stop irradiation of the light source of all sterilization devices 10 . In the present invention, a motion sensor is provided in the sensor unit 500 to detect a movement of a person or an animal to generate an abnormal signal. It is also obvious that sensors can be used, and that two or more types of sensors can be used in combination.

As such, when the emergency stop occurs, the control unit 400 transmits information about the occurrence of an abnormal situation to a portable terminal of a previously inputted operator 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 control unit 400, and the control unit 400 automatically transmits a signal according to the surrounding situation to the light source irradiation unit ( 200) to re-apply the power to resume irradiation of the light source. Depending on the usage aspect, it may be set so that irradiation of the light source can be resumed only when a separate input signal from the manager is generated. It is self-evident that such a setting method can be selectively set in consideration of the use environment and the like.

Next, the control unit 400 measures a preset time through a timer included therein to complete the sterilization by ending the set time or by terminating the irradiation of the light source through a stop signal applied from the outside (S400). At this time, as for the measurement time of the timer, the timer in which the emergency stop has occurred is temporarily stopped, and when the sum of the time before the emergency stop and the time after restarting after the emergency stop is the same as the previously input time, the light source irradiation is terminated.

Next, the sterilization state is visually confirmed by confirming the presence or absence of the experimental bacteria of the verification unit 900 attached to the inside of the sterilization space (A) (S500). The verification unit 900 is gradually reduced according to the exposure time to ultraviolet rays, which can be easily confirmed by the user with the naked eye. This process will be described in more detail through examples as follows.

After attaching the verification unit 900 to the light source irradiating unit 200 at a distance of about 2 m, the change of the verification unit 900 for each time period is checked as shown in Table 2 below. At this time, [Table 1] shows the verification unit 900 on which yellow bacteria and white bacteria not exposed to UV are smeared.

[Table 2] confirms the sterilization state according to the embodiment through the verification unit 900, and the sterilization time may differ depending on the environment of the actual sterilization space (A). Therefore, even if sterilization is performed for about 50 minutes, complete sterilization may not be achieved, so the reliability of sterilization can be improved by checking the sterilization state through the verification unit 900 . That is, instead of simply predicting the irradiation time of the light source and irradiating the light source only for a reference time and completing sterilization, the user directly checks the sterilization degree using the verification unit, so even if there is a time difference in sterilization depending on the environment Complete sterilization can be performed. As shown in [Table 2] above, if it is determined through the verification unit 900 that the experimental bacteria remain, re-sterilization can be performed by re-irradiating the light source for a predetermined time. In this case, the re-sterilization time may be variously set in consideration of the residual degree of the experimental bacteria confirmed by the administrator through the verification unit 900 . Since the re-sterilization process is the same as or similar to the light source irradiation process (S300) to the verification unit 900 confirmation process (S500) described above, a detailed description will be omitted. In addition, the re-sterilization process may be performed only the first time, or may be repeatedly performed depending on the state of the verification unit 900 checked after re-sterilization, and may re-operate a plurality of sterilization devices 10 at the same time, or some sterilization devices 10 ), it is self-evident that re-sterilization can be performed by re-operation.

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