Description

[0001] Sterilization and disinfection system in open space [0002]

The present invention relates to a space-open disinfection and disinfection system, and more particularly, to a space-open disinfection and disinfection system for disposing a target article in a closed space and irradiating ultraviolet rays A (UV-A) Disclosed is a system and method for disinfecting and sterilizing various objects in a space opened by natural light utilizing UV-B (UV-B).

Generally, most sterilizer products available on the market use ultraviolet C (UV-C) wavelength band known as sterilizing line of ultraviolet A, B and C, and have the most excellent sterilizing power among UV C 256.7nm is widely used.

Since this wavelength band is short wavelength among ultraviolet rays, it can access DNA such as bacteria / viruses and exhibits high energy enough to destroy it. Therefore, when direct light is irradiated to a person, it causes skin diseases and especially eye retina In order to prevent direct contact of skin and eyes with ultraviolet C (UV-C) light, sterilizer products must be made into products with UV-C lamps installed in a closed space.

This conflicts with the general understanding of consumers who want to sterilize a wide variety of products in a confined space.

In addition, if you look at a UV cup sterilizer in a public restaurant, you may find that you put a beverage cup in a sterilization space in a stack, and in this case, it will not have sterilizing power at all. This is a functional limit of ultraviolet C (UV-C), because ultraviolet C (UV-C) belongs to short wavelength of ultraviolet wavelength band. As a result, most of ultraviolet C (UV-C) disinfector has a disadvantage that the effective irradiation distance is only about 30 cm.

As such, since the effective irradiation distance is short, all the sterilizers are inevitably designed to insert the sterilizing object into the closed space so as to maintain an appropriate distance.

Although there is an ultraviolet sterilizer which overcomes this closed type and expresses as an open type, only a short distance irradiation by a short wavelength is performed by using the light source as the UV C (UV C) as it is. The object is firstly dried by wind and sterilized by ultraviolet C (UV-C), but the wavelength of wind itself is more likely to interfere with the irradiation of ultraviolet C (UV-C).

In addition, even in the case of an air purification / sterilization product using ultraviolet C (UV-C), air is continuously generated in the room due to a short irradiation distance, So that the air is sterilized instantaneously.

However, in contrast, the method of disinfecting daylight in a natural state is different from the method of manufacturing ultraviolet sterilizer as described above.

This is because the ultraviolet C does not play a role in disinfection by natural light. Of ultraviolet rays originating from the sun, ultraviolet C (UV-C) is mostly absorbed in the Earth's ozone layer and can no longer descend to the Earth's atmosphere and can only be artificially created in the laboratory.

As such, natural light that has been provided with the benefit of disinfection of human beings for a long time ago is composed of ultraviolet A (UV-A) and ultraviolet B (UV-B), and the sterilizing power does not reach ultraviolet C (UV-C).

Ultraviolet A (UV-A) is a low-energy ultraviolet light with a long wavelength range of 320 to 400 nm. It is known to occupy about 30% of natural light. It penetrates into the skin dermis because of its long wavelength and is known as a major cause of skin cancer and aging. UV-A has a function of drying a light-irradiated object, and it is utilized as a hardening agent system in the field of industry and the like .

Ultraviolet B (UV-B) is a medium-wavelength ultraviolet light of 280 ~ 320nm, which is known to occupy about 5% of natural light. It is stronger than UV-A and burns in a short time. '. It does not excel as UV C but it can exert sterilizing and disinfecting function. When it is applied to skin and hair of human and animal, it is important to produce vitamin D3 which strengthens immunity to human body. It also plays a role.

The biggest problem in disinfection treatment by natural light using UV-A and UV-B is that the sterilizing power is weaker than the UV-C sterilizer, (UV-A) and UV-B (UV-B) are not as much as UV-C, and they are exposed to the eyes and skin for a long time. It becomes dangerous.

Therefore, in order to overcome the unreasonableness of such a conventional ultraviolet C (UV-C) sterilizer and to sterilize various objects in a space opened with natural light utilizing UV-A (UV-A) and UV-B The need for an open-space sterilizing method of sterilization is increasing.

In addition, the control unit generates data on sterilization disinfection completion time according to lighting of the sterilizing illumination unit and harmful time data on which the ultraviolet rays are continuously exposed to the human body so that the UV-A LED and the UV-B LED of the sterilization illumination unit When the movement of the human body in the indoor space is detected in the lighted state, the residual time until the sterilization completion time is compared with the harmful time, and if the remaining time of the sterilization disinfection is shorter than the harmful time, And at least one of the LEDs of the sterilizing illumination unit is turned off when the sterilization disinfection completion remaining time is longer than the harmful time.

FIG. 1 is a view showing an example in which a space open type disinfection / disinfection system according to the present invention is applied to each space, and FIG. 2 is a block diagram showing a main structure of a space open type disinfection / disinfection system according to the present invention.

The sterilization and disinfection system according to the present invention includes a sterilizing lighting unit 10 installed in an open interior space to emit ultraviolet rays of a predetermined wavelength, A sensing unit 20 for sensing the movement of the human body in a predetermined area provided with the sterilizing illumination unit 10 and a control unit 20 for controlling the blinking of each LED provided in the sterilizing illumination unit 10 based on the value sensed by the sensing unit 20, And a control unit (30) for setting a lighting holding time.

The sterilizing illumination unit 10 is configured by combining a UV-A LED 11 of an ultraviolet A wavelength range and a UV-B LED 12 or an illumination LED 13 of an ultraviolet B wavelength range, 30, respectively.

1 (a), the sterilizing lighting unit 10 can be installed on the shelf of the sink to disinfect the articles stored in the upper part of the sink, such as a bowl on the sink, a sink ball, and the like. And (b) is capable of sterilizing a sink, a bathtub, and the like which are installed inside the toilet and installed inside the toilet. (C) sterilize the inside of the shoe box at the entrance of the entrance hall or the shoe removed, and (d) sterilize the bed and the bedding placed on the bed in the bedroom.

The sensing unit 20 senses the changed environmental information in the indoor space in which the sterilizing lighting unit 10 is installed and controls the LED blinking of the sterilizing lighting unit 10 based on the sensing value.

The sensing unit 20 includes a human body sensing unit 21 installed at one side of the room where the sterilizing lighting unit 10 is installed and sensing movement of the human body within a predetermined area, And a humidity sensing unit 23 installed in a room where the sterilizing illumination unit 10 is installed to sense humidity in a predetermined area.

The control unit 30 receives the sensing values sensed by the human body sensing unit 21, the light sensing unit 22 and the humidity sensing unit 23 and receives the sensed values of the UV-A LEDs An individual flashing control module 31 for controlling the LED lamp of at least one of the LED 11, the UV-B LED 12 and the LED 13 for illumination to blink; The UV-B LED 12, and the LED 13 for illumination, based on the values obtained by counting the signals transmitted from the sensing unit 20 in an accumulative manner over time, A flashing control module 32 for controlling the effective time at which any one or more of the LED lamps is turned on and at least one of the UV-A LED 11, the UV-B LED 12, And a user-specific flash control module 33 for controlling the flashing of one or more LED lamps.

The individual flashing control module 31 operates each LED corresponding thereto based on each sensed value sensed by the sensing unit 20. In particular, in addition to blinking of each type of LED, the number of blinking of each LED is also set to a sensing value So that it can be controlled selectively.

For example, a sterilizing illumination unit 10 composed of a UV-A LED 11, a UV-B LED 12 and an LED 13 for illumination is installed on the upper part of a kitchen sink shelf, The control unit 30 transmits a detection value to the human body detection sensor 40. When the user's access is detected from the human body detection sensor to the kitchen, The power supply to the UV-A LED 11 and the UV-B LED 12 is stopped so that the user approaching the kitchen is not exposed to the ultraviolet rays.

A value sensed by the humidity sensor 23 in the vicinity of the kitchen sink is transmitted to the controller 30. If the humidity value transmitted to the controller 30 is greater than a predetermined value, 11) is lit more than a conventional number of lights so that moisture around the kitchen sink is below a preset constant value.

If the humidity value sent from the humidity sensor 23 to the control unit 30 is lower than a predetermined value, the number of lighting of the UV-A LED 11 is reduced to the set number.

In addition, in the case of the light sensing unit 22, the power of the UV-A LED 11 and the UV-B LED 12 is stopped by sensing the light of the automatic flickering lamp at the entrance or the like of the entrance, 13) can be maintained.

In this manner, the individual flicker control module 31 controls the operation of each LED in accordance with the environmental condition sensed by the sensing unit 20, thereby increasing the sterilization efficiency in real time.

The user-specific flashing control module 33 is controlled in preference to the control command arbitrarily specified by the user, rather than the influence of the sensing value of the sensing section 20. [ For example, in order to disinfect the bedding on the bed in a state where the sterilizing lighting unit 10 is installed in the bedroom, the user can control the sterilizing lighting unit 10 during the entire period from the time of work to the time of work, , The control command of the user-designated flashing control module 33 is given priority even if another sensing value is transmitted to the control unit 30.

The automatic flashing control module 32 counts the time at which the sensing value sensed by the sensing unit 20 is transmitted to the control unit 30 and counts the signals transmitted from each sensing unit 20 in each time slot, The counted number of signals is counted to determine the cumulative count history, and the effective time for lighting a specific LED lamp in a time zone formed by a predetermined number of counts or more is set.

FIG. 3 is a table showing the average value of the cumulative number of human body detection counts per one hour in a certain area (bedroom, kitchen, toilet) of the indoor space over a time period, The human body sensing value sensed by the sensing unit 21 is transmitted to the controller 30 and the controller 30 generates a time value for each sensed sensing signal. The time value thus generated is cumulatively counted by the control unit 30 for each time slot, and is generated as a history information table counted for 24 hours.

As shown in the drawing, the human body detection cumulative counting value is generated from 5:00 pm to 1:00 am in the kitchen space, and it is not detected from 1:00 am to 4:00 am and the cumulative human body detection counting value is generated again from 5:00 am have. On the other hand, since the bedroom sleeps at night, the counting value is generated from 7:00 pm to 9:00 am on the following day, and the movement of the human body is not detected until the afternoon departure time (about 6:00 pm).

Based on the table generated in this manner, the operation of each LED of the sterilizing illumination unit is controlled.

That is, if the lighting reference value of the UV-A LED 11 and the UV-B LED 12 is set to be equal to or less than the cumulative counting value 1 in the automatic blinking control module 32, The UV-A LED 11 and the UV-B LED 12 are controlled to be automatically turned on from 11:00 to 1:00 pm and from 3:00 pm to 5:00 pm. In the case of the bedroom, the UV-A LED 11 and the UV-B LED 12 are automatically turned on from 9:00 am to 6:00 pm.

In addition, the table allows the accumulated count value to be updated in real time due to a change in the life pattern of the user or the like, so that the control setting is automatically changed according to the lighting reference value initially set by the user.

 In addition, the automatic blinking control module 32 may automatically control the user, and the user may optionally release the automatic blinking control state and optionally control the blinking control module 33 by the user.

3, the operation of the automatic blinking control module 32 according to human body detection has been described. However, in addition to the above, a UV-A LED 11 having a function of removing moisture by the above- As shown in FIG.

FIG. 4 is a table showing the number of cumulative counts of human body detection counts per hour in the kitchen and the average value for one month by detecting the humidity value. The lighting reference value of the UV-A LED 11 according to the time- And the humidity sensing value is set to 20, the UV-A LED 11 is automatically turned on by the automatic blinking control module 32 when the hourly humidity sensing value is 10 or more, When the sensing value is 20 or more, the number of lighting of the UV-A LED 11 lamp is controlled by the individual flashing control module 31 based on the humidity sensing value.

When the operation of the sterilizing illumination unit 10 is controlled by the individual flicker control module 31 considering the human body detection value prior to the humidity sensing value, the lighting reference value of the UV-A LED 11 is not based on the humidity sensing value A LEDs 11 are controlled on the basis of the human body detection sensing value and the number of lighting of the UV-A LED 11 lamp with respect to an excess value of the humidity sensing value within a time period during which the UV-A LED 11 is lit.

That is, even if the lighting reference value of the UV-A LED 11 is set to 10 according to the humidity value by time of day as in the description of FIG. 3, it is set at 10:00 am to 5:00 am, 11:00 am to 1:00 pm, And the UV-A LED 11 and the UV-B LED 12 are simultaneously turned on automatically by 5:00 PM and the humidity sensing value exceeds the value of 20 or more within the operation time of the UV-A LED 11 The number of lighting of the UV-A LED (11) lamp is controlled individually only at the sensed time zone of 1:00 am humidity sensing value 35, 2:00 am humidity sensing value interval 25. For example, the number of UV-A LED 11 lamps is set to 60% of the total number of UV-A LED 11 lamps when the humidity value is less than 20, The UV-A LED 11 is turned on at 1:00 am and 75% of the total number of lamps of the UV-A LED 11 is turned on. At 2:00 am, 65% of the total number of lamps are controlled to be turned on .

In addition, the control unit 30 generates sterilization disinfection completion time data according to lighting of the sterilizing illumination unit 10 within a predetermined space, and harmful time data in which the ultraviolet rays are continuously exposed to the human body. This time data is changed depending on the number of LEDs of the sterilizing illumination unit 10 lit.

When the movement of the human body is detected in the state where the UV-A LED 11 and the UV-B LED 12 of the sterilizing illumination unit 10 are lit, the disinfection completion time data and the harmful time data are compared with each other, Control the flashing of the lamp.

That is, when the remaining time from the control unit 30 to the disinfecting disinfection completion time is compared with the harmful time, if the disinfection completed remaining time is shorter than the noxious time, the sterilizing illumination unit 10 is kept lit, Is longer than the harmful time, at least one of the LEDs of the sterilizing illumination unit 10 is turned off to prevent harm to the human body.

The number of lights that are extinguished according to the degree of harmfulness of the human body can be set again in detail. That is, when the control unit 30 compares the time information as described above and continues to maintain the lighting state until the disinfecting completion time, if the UV-A LED 11, the UV-B LED 12 ) The number of lamps to be turned off is controlled separately. For example, the harmful rating variable according to the type of the UV-A LED 11, the type of the UV-B LED 12, and the number of lamps is generated, and compared with the harmful excess time, Respectively.

In addition, it is also possible to add the environmental weights according to the environment of the indoor space, and set the number of lights to be turned off for each lamp type. That is, in the case of the kitchen, the weight of the drying environment is larger, so that the environmental weight may be applied so as to reduce the rate at which the UV-A LED 11 is turned off.

Hereinafter, a method of disinfecting and sterilizing a space-open type according to the present invention will be described in detail.

FIG. 5 is a flow chart illustrating a procedure for sterilization of the open space according to the present invention. Referring to FIG. 5, a sterilizing lighting unit 10 including an LED assembly in which ultraviolet rays are emitted and an LED 13 for illumination is combined is installed in an open interior space requiring sterilization (S510).

In addition, the sensing unit 20 may be installed to sense humidity, brightness information, or motion information of a human body in a predetermined area in which the sterilizing lighting unit 10 is installed, The environment information value within the installation space is sensed through the controller 20 (S520).

The sensed value of the sensing unit 20 is transmitted to the control unit 30. The control unit 30 of the present invention controls the automatic flashing control module 32, the individual flashing control module 31, To control the LED lighting of the sterilizing lighting unit 10.

The sensing value transmitted from the sensing unit 20 is first sensed by the automatic flash control module 32 from the UV-A LED 11, the UV-B LED 12, The control command is generated so that the LED 13 is automatically turned on for each time zone according to a predetermined setting reference (S530). A LED 11 and a UV-B LED (not shown) are controlled by the individual flicker control module 31 based on the sensed values of the human body sensing unit 21, the light sensing unit 22 and the humidity sensing unit 23. [ 12 and the illumination LED 13 lamp (S540).

Finally, the lighting control is performed by the user's designated blinking control module 33 to set the control command directly in order to give priority to the lighting control in the control module (S550) The LEDs of the sterilizing lamps and the like are turned on according to the command so that the disinfection is performed in the opened indoor space (S560).

In this manner, the control command is generated in three steps so that more precise control can be performed according to the surrounding environment, so that the ultraviolet rays are not exposed to the user in the open space.

Hereinafter, an example of a method of using the space open type disinfection / disinfection system according to the present invention by specific spaces such as a toilet, a kitchen, a front door, a bedroom, etc. will be described in detail.

The combination of the sterilizing illumination unit 10 for optimal sterilization and disinfection in the interior space of the toilet is designed and manufactured at a ratio of 5: 3: 2 for the illumination LED 13, the UV-A LED 11 and the UV-B LED 12 .

The disinfection lighting unit 10 is not always controlled by the automatic flash control module 32 and the UV-A LED 11, the UV-B LED 12, The inside of the bathroom is disinfected, the user senses the reception of money to the inside of the toilet through the human body sensing part 21, or the inside of the bathroom is lighted by the light sensing part 22, And if the sensing value of the sensing unit 20 is not sensed again within a predetermined time, the LED is immediately turned on so that the room is always kept comfortable.

The combination of the sterilizing illumination unit 10 for optimal sterilization and disinfection in the interior space, such as the toilet in the kitchen sink space or the entrance hall, is provided by the illumination LED 13, the UV-A LED 11 and the UV- : 3: 2 ratio.

Especially, water is frequently used in the kitchen sink space, and there is a need to quickly remove the moisture by causing the bacterial propagation actively by the ambient moisture around the sink to actively propagate the bacteria. In order to quickly remove the moisture in the kitchen space, it is preferable to control the drying by the individual flicker control module 31 according to the humidity value detected in real time by the humidity sensor 23.

That is, the number of lighting of the lamp of the UV-A LED 11 is adjusted according to the change of the humidity value detected in real time, and when the humidity is high, the lamp is turned on more rapidly and dried quickly. In the nighttime or when the user does not use the kitchen, the automatic ultraviolet LED is turned on for a long time through the automatic flicker control module 32 to sterilize a bowl, a knife, and a cloth placed on the upper part of the kitchen sink.

As described above, the present invention can sterilize all the articles that can be placed in the kitchen sink in an open space at all times, and sterilize the sink bowl and the vicinity of the drain hole. Also, there is no need to place an article inside the closed space for sterilization as in the prior art.

In the case of the entrance hall, it is preferable that the user does not stay in the room for a long period of time, such as a toilet, so that it is controlled as the sterilization method in the toilet space.

The combination of the sterilization lighting unit 10 for optimal disinfection in the bedroom is designed in a ratio of 5: 5 for the UV-A LED 11 and the UV-B LED 12 and is attached to the wall near the bed in the bedroom .

Bedrooms are usually reserved for the user to sleep at night, and are vacated for outdoor activities in the morning. Accordingly, in the bedroom, the user is allowed to light up for a long time through the automatic flashing control module 32 for each time zone such as the sleeping time and the commute time, and further, in order to increase the sterilization effect of the bedding disinfection, The UV-A LED 11 is turned on by 100%, and the UV-B LED 12 is turned on by 50% for a long time, thereby exerting a unique function of the bedding sterilizer.

House dust mite is the biggest problem in the bedding in the bedroom, and it is difficult to provide long-time light to the bedding with the conventional bedding sterilizer equipped with the UV-C LED, and it is usually exposed for 1 to 2 seconds on the bedding surface, The tick can not be removed. It is practically impossible to irradiate ultraviolet rays for more than 20 seconds by dividing the entire area of the bedding for a long time.

On the other hand, in the present invention, the house-mite is not directly killed by the UV-C, but the house-mite is breathing in the humid environment and the UV-A LED 11 is irradiated to the bedding for a long time, By eliminating moisture and directly killing germs that can feed on house dust mite by long-time irradiation of UV-A LED 11, bedding can no longer serve as a habitat for house dust mite.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the scope of the appended claims should include all such modifications and changes as fall within the scope of the present invention.
