Let's look at each component in detail.

[Frame part]

The frame part 100 may include a first column 110, a second column 120, an upper connection part 150, a protrusion 160, and a bottom plate 170.

The first pillar 110 and the second pillar 120 may be elongated in the vertical direction. The second pillar 120 may be spaced apart from the first pillar 110 in the first direction. Here, the first direction may mean a left-right direction in FIG. 1.

A first ultraviolet light emitting part 200a and a second ultraviolet light emitting part 200b may be respectively installed in the first column 110 and the second column 120 so as to be movable vertically.

A user may be positioned between the first pillar 110 and the second pillar 120 (FIGS. 5 to 9 ).

In this way, the ultraviolet sterilization device 10 includes the first column 110 extending in the vertical direction, and the ultraviolet light emitting unit 200 is installed to be movable up and down on the first column 110, so that it has a simple configuration. It is possible to form an ultraviolet sterilization device 10 in which the ultraviolet light emitting unit 200 moves up and down easily at low cost.

In addition, the ultraviolet sterilization device 10 further includes a second column 120 extending in the vertical direction and spaced apart from the first column 110 in the first direction, and the ultraviolet light emitting unit 200 is the first column ( By being installed to be movable vertically on each of the 110) and the second column 120, it is possible to form an ultraviolet sterilization device 10 in which the ultraviolet light emitting unit 200 moves vertically from both sides with a simple configuration at low cost. .

The upper connector 150 may connect the upper portions of the first pillar 110 and the second pillar 120. Accordingly, since the first pillar 110 and the second pillar 120 are stably supported, durability of the ultraviolet sterilization device 10 may be improved.

The protrusion 160 may be formed to protrude in the second direction from the upper connection portion 150 between the first pillar 110 and the second pillar 120. Here, the second direction may mean a front-rear direction in FIG. 1.

The photographing part 400 may be installed on the protrusion 160 toward the user. Accordingly, the photographing unit 400 can be stably installed toward the user at low cost with a simple configuration.

Specifically, one end of the protrusion 160 may extend downward, and an inclined surface inclined at a predetermined inclination toward the user may be formed inside a lower portion of the downwardly extended portion. The photographing unit 400 may be installed on the inclined surface.

The bottom plate 170 may be disposed below the first pillar 110 and the second pillar 120 (eg, the bottom), and may support the first pillar 110 and the second pillar 120. Accordingly, the ultraviolet sterilization device 10 can be easily moved.

A fifth ultraviolet light emitting unit 300 that irradiates ultraviolet rays upward may be installed on the bottom plate 170. The user may be positioned above the fifth ultraviolet light emitting unit 300 installed on the bottom plate 170.

[Ultraviolet light emitting part]

The ultraviolet light emitting units 200 and 300 are installed in the frame unit 100 to irradiate ultraviolet rays to a user. Accordingly, sterilization can be performed simply, quickly and conveniently at low cost for the user. Here, sterilization of the user may mean sterilization of pathogens present in the clothing worn by the user.

The first ultraviolet light emitting unit 200a and the second ultraviolet light emitting unit 200b may be installed to be movable vertically on the first pillar 110 and the second pillar 120, respectively. For example, the ultraviolet light emitting unit 200 may include a driving unit (not shown), and may be controlled by a control unit (not shown) to move up and down.

In this way, since sterilization can be performed while the ultraviolet light emitting unit 200 moves up and down, cost can be reduced by miniaturizing the ultraviolet light emitting unit 200, and sterilization can be performed intensively for a specific area.

The first ultraviolet light emitting unit 200a and the second ultraviolet light emitting unit 200b can irradiate ultraviolet rays in a direction facing each other so as to face a user positioned between the first pillar 110 and the second pillar 120. have. Accordingly, since ultraviolet rays can be irradiated to the user without a shaded area, sterilization can be thoroughly performed.

Meanwhile, as shown in FIGS. 5 to 9, when the user faces the front side and rotates approximately 90 degrees so that the user faces the side as shown in FIGS. 10 and 11, the sterilization can be performed more thoroughly.

A light shielding film 230 for limiting an irradiation angle of ultraviolet rays may be provided around the periphery of the ultraviolet emission region A in which ultraviolet rays are emitted among the ultraviolet light emitting units 200. For example, in FIGS. 1 to 11, light shielding films 230a and 230b may be provided to protrude in the first direction above the periphery of the ultraviolet emission region A.

The light-shielding film 230 may be, for example, a matt black anodizing treatment having a light reflectance of 10% or less. Accordingly, it is possible to prevent the ultraviolet rays from being reflected and diffused by the light shielding film 230.

Accordingly, as shown in FIGS. 5 to 8, ultraviolet rays may be irradiated in a horizontal direction or only at an angle that is inclined downward than in the horizontal direction. That is, irradiation of ultraviolet rays at an angle that is inclined upwards than in the horizontal direction can be suppressed.

Accordingly, as shown in FIGS. 6 and 7, even if the ultraviolet light emitting unit 200 moves upward and irradiates ultraviolet rays to sterilize the top worn by the user, it is not possible to irradiate ultraviolet rays to the skin of the user's face or the user's eyes. Can be prevented.

As described above, the light-shielding film 230 is provided around the periphery of the ultraviolet ray emitting region A in which ultraviolet rays are emitted, so that ultraviolet sterilization is possible for the user at low cost with a simple configuration. It can be done safely.

On the other hand, since ultraviolet (UV) rays cannot penetrate the clothing worn by the user, if ultraviolet rays (UV) are irradiated on the clothing worn by the user, the user can be safe from DNA destruction by ultraviolet rays (UV).

As shown in FIGS. 5 to 11, when the user wears long pants, if the light shielding films 230a and 230b are provided only above the periphery of the ultraviolet emission region A, ultraviolet sterilization can be safely performed for the user.

However, as shown in FIGS. 12 to 15, when the user wears shorts, the light shielding films 230a and 230b are not only at the upper portions 230a1 and 230b1 around the ultraviolet emission region A, but also at the lower portions 230a2 and 230b2. It must be provided so that ultraviolet sterilization can be safely performed for the user.

The fifth ultraviolet light emitting unit 300 may be installed on the bottom plate 170 to irradiate ultraviolet rays upward. Accordingly, sterilization can be performed simply, quickly and conveniently at low cost on the bottom surface of the user's shoe positioned above the fifth ultraviolet light emitting unit 300.

[Photographing Department]

The photographing unit 400 may be installed in the frame unit 100 to photograph a user. For example, the photographing unit 400 may be installed on the protrusion 160 toward the user.

The photographing unit 400 may be composed of at least one of a monocular (mono) camera, a binocular (stereo) camera, a depth camera, an infrared camera, a lidar, and an LRF sensor.

In addition, the photographing unit 400 may be connected to a control unit (not shown) to transmit the captured image information to the control unit. Here, the image information may be composed of at least one of visible image information, depth image information, and infrared image information.

[Control unit]

The controller (not shown) may distinguish between the user's skin and the clothing worn by the user from the image information captured by the photographing unit 400. Specifically, the control unit may receive image information from the photographing unit 400, and based on at least one of a color value, a depth value, or a temperature value included in the transmitted image information, the user's skin and the clothing worn by the user Can be distinguished.

For example, the controller may recognize a portion of the visible image information whose color value corresponds to a skin color as skin, and recognize a portion that is not as a garment.
A specific method of distinguishing skin from clothing follows known techniques.

Accordingly, since the user's skin and clothing can be effectively classified at low cost, sterilization can be safely performed for the user.

In addition, the controller may control the ultraviolet light emitting unit 200 to irradiate ultraviolet rays only to clothes worn by the user based on this. For example, since the control unit can know in advance the irradiation angle of the above-described ultraviolet light emitting unit 200, the ultraviolet light emitting unit is moved up and down as shown in Figs. 5 and 6 and 13 and 15. (200) can be irradiated with ultraviolet rays in the height section where only the garment is present. At this time, the user can increase the height section in which only clothes are present by raising the hand up to the height of the head as shown in FIGS. 5 to 17. More specific methods follow known techniques.

At this time, when there are a plurality of ultraviolet light emitting units 200, such as the first ultraviolet light emitting unit 200a and the second ultraviolet light emitting unit 200b, the control unit sets each of the ultraviolet light emitting units 200 individually. It can be moved up and down.

In this way, by controlling the ultraviolet light emitting unit 200 to separate the user's skin and the clothing worn by the user from the image information photographed by the photographing unit 400 and irradiate ultraviolet rays only on the clothing, ultraviolet rays are applied to the user. Sterilization can be carried out safely.

16 and 17 are perspective views and plan views showing an ultraviolet sterilizing device according to another embodiment of the present invention.

16 and 17, the ultraviolet sterilization device 20 according to another embodiment includes a frame unit 100, an ultraviolet light emitting unit 200 and 300, a photographing unit 400, and a control unit (not shown). It can be configured to include. Only differences from the ultraviolet sterilization apparatus of FIGS. 1 to 14 will be described.

The frame unit 100 may include a first pillar 110 and a second pillar 120 as well as a third pillar 130 and a fourth pillar 140.

The pillars 110, 120, 130, 140 are arranged so that the line segment connecting the first pillar 110 and the second pillar 120 and the line segment connecting the third pillar 130 and the fourth pillar 140 cross each other. Can be placed.

In addition, the first pillar 110, the second pillar 120, the third pillar 130, and the fourth pillar 140 may be spaced apart from each other.

The ultraviolet light emitting units 200a, 200b, 200c, and 200d may be respectively installed in the first pillar 110, the second pillar 120, the third pillar 130, and the fourth pillar 140 so as to be movable vertically. have.

A user may be positioned between the first pillar 110 and the second pillar 120 and between the third pillar 130 and the fourth pillar 140.

The controller (not shown) emits ultraviolet rays by moving the ultraviolet light emitting units 200 installed in the first pillar 110, second pillar 120, third pillar 130, and fourth pillar 140, respectively, up and down. The unit 220 may irradiate ultraviolet rays only to the clothing worn by the user.

The control unit may individually move each of the ultraviolet light emitting units 200a, 200b, 200c, and 200d up and down.

Accordingly, since ultraviolet rays can be irradiated from four directions surrounding the user, sterilization can be performed more quickly and thoroughly. In addition, since the sterilization is thoroughly performed without the user rotating or changing the posture, the sterilization can be performed more conveniently.

18 to 20 are a front view and a plan view showing a fifth ultraviolet light emitting unit according to another embodiment of the present invention.

18 to 20, a fifth ultraviolet light emitting unit 300 according to another embodiment includes a light emitting unit 310, a distance sensor 320, a substrate 330, and a tempered glass 340. Can be.

Each of the plurality of light emitting units 310 may irradiate ultraviolet rays upward.

The plurality of distance sensors 320 may be respectively disposed near at least some of the light emitting units 310. The distance sensor 320 may measure a distance to an object placed above it.

A light emitting unit 310 and a distance sensor 320 may be disposed on the upper surface of the substrate 330.

The tempered glass 340 may be disposed above the light emitting unit 310 and the distance sensor 320, and a user may be positioned on the upper surface of the tempered glass 340.

The control unit (not shown) of the UV sterilization device may receive distance information about the distance measured from the distance sensor 320, and the user's foot or shoe among the plurality of light emitting units 310 The light emitting unit 310 determined to be positioned above may be selected, and only the selected light emitting unit 310 may be irradiated with ultraviolet rays.

For example, as shown in FIGS. 18 and 19, a plurality of distance sensors 320 may be disposed near a plurality of light emitting units 310 disposed in the middle of the fifth ultraviolet light emitting unit 300, and By measuring the distance to the placed object, distance information can be transmitted to the control unit. However, it is not limited to this configuration.

In other words, unlike the drawings, the plurality of distance sensors 320 are not only the light-emitting unit 310 disposed in the middle of the fifth ultraviolet light-emitting unit 300, but also light emission disposed in all parts of the fifth ultraviolet light-emitting unit 300. It may be disposed near the unit body 310.

When a plurality of distance sensors 320 are widely spread and disposed near the light emitting unit 310 disposed in all portions of the fifth ultraviolet light emitting unit 300, the control unit may The entire area where the shoes are located can be recognized.

However, as shown in FIGS. 18 and 19, when the distance sensor 320 is intensively disposed near the light emitting unit 310 in a partial region (eg, the middle part) of the fifth ultraviolet light emitting unit 300, the control unit is Based on the information, the entire area can be estimated. That is, based on the distance information received from the distance sensor 320 that is intensively arranged in a partial area, the control unit determines the entire area (B of FIG. 18 or C of FIG. 19) that is determined to be placed on the upper side. Can be estimated.

Specifically, for example, in FIGS. 18 and 19, the control unit is based on the distance information received from the distance sensor 320 intensively disposed in the middle of the fifth ultraviolet light emitting unit 300. The width can be recognized. The controller may estimate the total area B or C by calculating the length of the user's foot or shoe corresponding to the width.

The controller may select the light emitting unit 310 corresponding to the entire area, and irradiate only the selected light emitting unit 310 with ultraviolet rays.

Accordingly, since the ultraviolet rays irradiated from the fifth ultraviolet light emitting unit 300 can be accurately irradiated only to the user's feet or the bottom of the shoes, ultraviolet sterilization can be performed more safely for the user. In particular, even when the user wears shorts, it is possible to prevent UV rays from being irradiated to the skin of the user's legs.

21 is a cross-sectional view showing an ultraviolet light emitting unit according to another embodiment of the present invention.

Referring to FIG. 21, an ultraviolet light emitting unit 200 according to another embodiment may include a plurality of light emitting units 210 and a parallel light lens 220 provided on the front surface of the light emitting unit 210. . The parallel light lens 220 may replace the light blocking layer 230 described above.

Accordingly, the ultraviolet rays emitted from the light emitting unit 210 are not diffused, but are condensed by the parallel light lens 220 to be irradiated only in a direction parallel to one direction (eg, horizontal direction), so that sterilization can be effectively performed. In addition, since the irradiation angle of ultraviolet rays is reliably limited, sterilization can be performed more safely by effectively preventing ultraviolet rays from being irradiated to the user's skin.

The parallel light lens 220 may be formed by forming a plurality of lenses 222 as a layer. For example, as shown in FIG. 21, the collimated light lens 220 may be formed of a layer of four planar convex lenses 222a, 222b, 222c, and 2224d. The radiuses of curvature of the lenses 222 of neighboring layers may be different from each other.

Accordingly, with a simple configuration, ultraviolet rays can be condensed and stably irradiated in a direction parallel to one direction.

Each of the parallel light lenses 220 may be provided on the front surface of the plurality of light emitting units 210, and the parallel light lenses 220 respectively provided on the front surface of the light emitting units 210 adjacent to each other are planar convex forming each layer. The lenses 222 may be in contact with each other. Accordingly, the collimated light lens 220 may form a lens arrangement.

When the collimated light lens 220 is composed of a plurality of lens 222 layers, the collimated light lenses 220 may contact each other between the lenses 222 forming each layer. Accordingly, the collimated light lens 220 may form a lens arrangement for each layer.

For example, as shown in FIG. 21, four planar convex lenses 222a, 222b, 222c, and 2224d each provided on the front surface of the light emitting unit 210a and the neighboring light emitting unit 210b are The lenses 222 may be in contact with each other. Accordingly, since each layer of the collimated light lens 220 may form a lens arrangement, the collimated light lens 220 may be formed by forming a layer of four lens arrays.

Accordingly, when manufacturing the collimated light lens 220, there is no need to assemble after manufacturing the lens 222 for each light emitting unit 210, and since it is sufficient to manufacture the lens array for the entire light emitting unit 210, the manufacturing cost Can be saved.

Likewise, even when the collimated light lens 220 is composed of a plurality of layers of lenses 222, there is no need to assemble the lenses 222 forming a plurality of layers for each light emitting unit 210, respectively, and the light emitting unit 210 ) After manufacturing the lens array for each layer for the whole, it is possible to reduce the manufacturing cost because it is necessary to assemble the lens array by placing layers.

It is obvious that transformations can be made. In addition, even if not explicitly described and described the operating effects according to the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effects by the configuration should also be recognized.
