Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a diagram showing a schematic configuration of a sterilization and sterilization apparatus according to an embodiment of the present invention.

The sterilization and sterilization device 1 according to an embodiment of the present invention is installed near the handle of the door and irradiates ultraviolet rays to the handle to sterilize the handle so as to suppress the spread of pathogens through the handle in homes and public places. Device.

Specifically, the sterilization and sterilization device 1 according to an embodiment of the present invention includes a bracket 100 and a body 200.

The bracket 100 is a member that is installed on the door, and provides a function to fix the main body 200 to the door, and at the same time, allows the main body 200 to be attached to and detached from the door. Is absent.

These brackets 100 are spaced apart from each other by a predetermined interval on the upper part of the handle formed on the door.

The main body 200 is fastened to the fastening bracket 100 and fixedly installed on the handle of the door, and the handle is sterilized by irradiating ultraviolet rays with the handle.

Referring to FIGS. 2 and 3 together, the main body 200 includes a housing 210 having an opening formed at a lower portion thereof, at least one ultraviolet light emitting module 220 installed at the lower end of the housing to irradiate ultraviolet rays through the opening, A front detection sensor 230 installed at the front of the housing 210 to detect a user approaching the door, a lower detection sensor 240 installed at the bottom of the housing to detect a user near the handle, the A controller 250 for controlling the ultraviolet light emitting module according to different operation modes based on the detection result of the front detection sensor and the lower detection sensor, and a battery 260 for supplying power required for the operation of the main body 200 do.

The housing 210 is a member defining the outer shape of the main body 210 as shown in FIG. 3, and an opening is formed in the lower portion of the housing 210 so that ultraviolet rays radiated through the ultraviolet light emitting module 220 to be described later are By being irradiated through, the ultraviolet rays can irradiate the handle part.

On the inside and outside of the housing 210, an ultraviolet light emitting module 220, front/rear detection sensors 230 and 240, a controller 250 and a battery 260, which will be described later, may be installed. In addition to this, in addition to this, an LED indicating an operation state may be installed on the front surface of the housing 210, and a charging port for charging the battery 260 may be formed on one side or rear side.

The material and shape of the housing 210 are not limited.

The ultraviolet light emitting module 220 may be in the form of an ultraviolet LED, and a plurality of ultraviolet light emitting modules 230 are arranged in a line at predetermined intervals.

The front detection sensor 230 is installed on the front side of the housing 210 and can detect a user located in the front side of the housing 210. Accordingly, when the housing 210 is installed on the door, the front detection sensor 230 may detect a user located in front of the door. The front sensor 230 may be in the form of any one of various known proximity sensors.

The lower detection sensor 240 is installed under the housing 210 and may detect a user located under the housing 210. Accordingly, when the housing 210 is installed on the door, the downward detection sensor 230 may detect a user (eg, hand) located on the handle of the door. The downward detection sensor 230 may be in the form of any one of various known proximity detection sensors.

The controller 250 may control the overall operation of the main body 200. For example, the controller 250 may process tasks such as on/off of the main body 200 and control according to user manipulation.

In particular, the control unit 250 according to the present invention distinguishes whether the user is a user simply passing through a door or a user directly using a door (handle), and performs different operations according to the result of the classification.

Specifically, the control unit 250 maintains the standby mode when the user is not detected in front of the user or the user is a user who simply passes the door. If it is determined that the user directly using the door is detected, the control unit 250 switches from the standby mode to the sterilization mode. Is converted.

Here, the standby mode is a mode in which the battery is saved by operating only the minimum power for user detection of the sterilization and sterilization device 1, and the sterilization mode is a mode in which sterilization and disinfection is performed by irradiating ultraviolet rays on the handle after the user has used it. have.

To this end, the control unit 250 may determine that the user is a user who directly uses the door when a user is simultaneously detected by the front sensor 230 and the lower sensor 240.

In this case, the control unit 250 switches from the standby mode to the sterilization mode, and when the sterilization mode is activated, the user uses the handle until the user is not detected at the same time in the front sensor and the lower sensor. Wait until it disappears from the door.

Thereafter, the controller 250 measures a duration at which the user is not detected at the same time in the front detection sensor and the lower detection sensor, and when the measured duration passes a preset first reference time, the ultraviolet light emitting module is After the handle is sterilized by ultraviolet rays by operating for a reference time, the sterilization mode is switched to the standby mode.

For example, the control unit 250 detects a user at the same time by the front detection sensor and the lower detection sensor (a state in which the user is holding the handle and using the door), and then the front detection sensor and the lower detection sensor do not simultaneously detect the user. If not, the duration is measured and the UV light is irradiated after the user leaves by operating the UV light emitting module 220 when a preset reference time (1 to 10 seconds, preferably 5 seconds, less than the first reference time) elapses. Make it possible.

At this time, the control unit 250 may improve the sterilization effect by ultraviolet rays by operating the ultraviolet light emitting module 220 for 10 to 50 seconds (preferably 20 seconds or more, hereinafter, the second reference time).

In this process, the control unit 250 controls at least one of the front detection sensor 230 and the lower detection sensor 230 while the ultraviolet light emitting module 220 is operated for the second reference time. When detected, the ultraviolet light emitting module is temporarily turned off and temporarily waits until the user is not detected at the same time by the front sensor and the lower sensor.

This is to prevent ultraviolet rays from being irradiated to a user who has passed in the sterilization process using ultraviolet rays.

Thereafter, the control unit 250 operates the ultraviolet light emitting module again when the duration in which the user is not detected simultaneously by the front sensor and the lower sensor again passes the first reference time.

For example, the front sensor detects when the human body is approaching, and the sensor in the direction of the door handle (lower human body detection sensor) detects the human body (hand), and UV sterilization irradiation for 10 to 40 seconds ( However, if the hand does not move away from the handle, UV sterilization should not be performed even if the front sensor is detected).

If the sensor on the front panel detects the sterilization process 1 to 10 seconds after detecting the hand (user), the sterilization operation should be stopped, and if the person is out of position afterwards, the remaining time after 1 to 10 seconds is examined or 10 Re-sterilize irradiation for ~40 seconds.

Sterilization irradiation for 10 to 40 seconds at 8-hour intervals from the time not detected by two sensors (If more than one sensor detects, stop the operation and sterilize the remaining time after the person leaves, or perform sterilization investigation again for 10 to 40 seconds. .

In some other embodiments, the sterilization and sterilization apparatus 1 according to the present invention may further include an array control unit for varying the arrangement shape of the plurality of ultraviolet light emitting modules corresponding to the shape of the handle.

In this regard, it will be described with reference to FIGS. 4 to 6 together.

4 to 6 are views for explaining a specific configuration and function of the arrangement control unit.

The arrangement control unit 300 according to the present invention is characterized in that the plurality of ultraviolet light emitting modules 220 arranged in a row are bent or bent so that each of the ultraviolet light emitting modules 230 have the same distance from the handle. To do.

To this end, the array control unit 300 includes a lower frame 310, an upper frame 320, a shape measuring module, and a length adjusting member 320.

The lower frame 310 is installed at the lower end of the housing, and specifically, may be formed at a position that can be exposed from the outside through an opening of the housing 210.

The lower frame 310 may have a plurality of the ultraviolet light emitting modules arranged along the length direction, and may be formed of a flexible material such as rubber/silicone. Accordingly, when the lower frame 310 is bent or bent, the arrangement shape of the plurality of ultraviolet light emitting modules arranged along the length direction of the lower frame 310 is also changed.

Meanwhile, although not shown, a shape measuring module for measuring information on the shape of the handle may be installed on the lower surface of the lower frame 310. For example, the shape measurement module may be a camera module, and in this case, the lower surface of the housing 310 may be photographed at predetermined time intervals to obtain information on the shape of the handle.

The upper frame 320 is installed inside the housing 210 and is installed vertically above the lower frame 310.

A plurality of length adjustment members 330 to be described later may be installed inside the upper frame 320.

The length adjustment member 330 is a member having one end connected to the inner side of the upper frame, the other end contacting the lower frame, and installed at predetermined intervals along the length direction of the lower frame.

It is preferable that the length adjustment member 330 is provided in a form capable of adjusting the length. For example, the length adjustment member 330 may be in a form in which multi-stage cylindrical members whose diameter decreases gradually are continuously combined, and thus the length may be contracted or elongated while the cylindrical member is inserted or protruded.

This length adjustment member 330 allows the upper frame 320 to be connected to the lower frame 310, and at the same time, the length of each length adjustment member 330 is independently variable, thereby changing the shape of the lower frame 310. It is characterized by transforming.

To this end, the control unit 350 analyzes the shape of the handle measured by the shape measurement module so that all ultraviolet light emitting modules formed in the lower frame can be formed to be spaced apart from the handle by the same distance, and It may be characterized by partially extending or contracting the adjustment member.

For example, as shown in Figure 5, the control unit 350 analyzes the photographed image received from the shape measurement module, and if it is determined that the handle is straight, all the length adjustment members 330 maintain the same length, so that the ultraviolet light emitting member Can be controlled so that they can be arranged in a line.

On the other hand, as shown in FIG. 6, when the control unit 350 analyzes the photographed image received from the shape measurement module and determines that the handle is circular, the length adjustment member 330 gradually increases as it goes from the center to the outer side. Let's do it.

At this time, the upper frame 320 is fixedly installed on the housing 310, but the lower frame 310 is in a state connected to the upper frame 320 only through the length adjusting member 330, so each length adjusting member as described above When the length of 330 is controlled, the ultraviolet light emitting members are arranged in a curved shape.

Therefore, even if the shape of the handle is various, it is possible to provide an optimized sterilization effect.

Although the above has been described with reference to embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention described in the following claims. I will be able to.
