Description

UV Sterilizer {UV Sterilizer}

The present invention relates to a UV sterilization device. More specifically, it is installed in the storage space of an installation object and detects whether the storage space is open, and stops irradiating UV light when the storage space is open, thereby allowing the user to use the storage space during UV sterilization. It relates to a UV sterilizing device that prevents the user's body from being exposed to UV light even when the device is opened.

Ultraviolet (UV) refers to electromagnetic waves in the 10 to 400 nanometer wavelength range (750 THz) that are invisible to the human eye and are adjacent to the purple band in the spectrum.

The wavelength of ultraviolet light is shorter than visible light and longer than X-rays. Long-wavelength ultraviolet rays do not have enough energy to ionize atoms, but they can cause chemical reactions in substances to emit light or produce a fluorescent effect. Therefore, ultraviolet rays not only heat living organisms, but also cause molecular interactions within the body. Electromagnetic waves with sufficiently high energy can destroy biological tissue and thus destroy small microorganisms. Due to this effect, ultraviolet rays are used for sterilization in everyday life.

Sterilization devices using ultraviolet rays are generally used in devices that are concerned about contamination by microorganisms, such as dedicated sterilizers for sterilizing medical instruments, tableware, etc., or refrigerators.

Recently, users can arbitrarily install and sterilize products for which UV sterilization devices were not applied during production, such as the "portable sterilization device using UV LED" (hereinafter referred to as 'conventional patent') disclosed in Patent Publication No. 10-2015-0028154. A sterilization device that can do this is being developed.

However, if the human body is overexposed to ultraviolet rays, it causes skin damage such as age spots, freckles, and sunburn, and in severe cases, it can cause skin cancer. Therefore, in order to prevent users from being exposed to ultraviolet rays, products to which a UV sterilizing device is applied during production are designed so that UV light irradiation is stopped when the product door is opened.

However, in the case of a UV sterilizing device that is installed and used arbitrarily by the user, as in the conventional patent, it is not linked to the product door, so UV light irradiation is not stopped even if the user opens the door while the installed UV sterilizing device is sterilizing, so the user cannot use the UV sterilizing device. There is a problem that there is a high possibility of exposure to light.

Figure 1 is a diagram showing the coupling relationship between the mounting part and the main body of a UV sterilizing device according to an embodiment of the present invention, and Figure 2 is a diagram showing the main body according to an embodiment of the present invention.

The UV sterilizing device according to an embodiment of the present invention can be used by being mounted on an installation object that has an opening and closing means and a storage space. Specifically, the installation object is provided with an opening and closing means such as a door or lid that can be opened and closed by the user, and a storage space whose opening or closing is determined depending on the open and closed state of the opening and closing means, such as a vehicle console box, vehicle glove box, closet, and trash can. , toilets, etc. may be installation objects.

The UV sterilizing device according to this embodiment is installed on the inner wall constituting the storage space of the installation object and can sterilize the storage space and the items stored in the storage space through UV light irradiation.

To this end, the UV sterilizing device may be configured to include a mounting portion 10 mounted on an installation object, as shown in FIG. 1, and a main body portion 30 that is coupled to the mounting portion 10 and irradiates UV light.

The mounting unit 10 may be fixedly mounted on an installation object using double-sided tape or screws. At this time, the mounting unit 10 may be mounted on one side of the inner wall constituting the storage space so that the UV light irradiation direction of the main body unit 30 coupled to the mounting unit 10 is toward the storage space.

The main body portion 30 can be coupled to the mounting portion 10 in various detachable coupling methods. For example, at least a portion of the mounting portion 10 is made of a magnetic material, and the mounting portion 10 and the main body portion 30 may be coupled to each other using magnetism, but the present invention is not limited thereto.

As shown in FIG. 2, the main body 30 includes a main body 31 forming the outer shape of the main body, one or more UV modules 32 disposed in the main body and operating to irradiate UV (ultraviolet) light, and It may be configured to include a status indicator light 33 that provides various status information about the UV sterilizing device to the user.

The main housing 31 may be provided with an internal space capable of accommodating the UV module 32. In addition, the main body housing 31 has a mounting surface disposed on one side, and the mounting surface may be engraved in a shape corresponding to the mounting part 10 so that the mounting part 10 can be accommodated and mounted. At this time, when the mounting portion 10 and the main body portion 30 are coupled to each other using magnetism as described above, at least a portion of the mounting surface of the main body housing 31 may be made of a material such as iron or magnet. .

One or more through-holes for irradiating light from the accommodated UV module 32 may be formed on the other side of the mounting surface of the main housing 31. The lamp of the UV module 32 may be disposed in the through hole, and thus the light emitted from the UV module 32 may be irradiated in a direction opposite to the mounting surface.

The status indicator light 33 is placed on one side of the main housing 31 and can emit light of various colors. It can provide various status information about the UV sterilizing device by the color of the light it emits or by flashing. there is. At this time, the status information provided by the status indicator 33 may include whether the UV module 32 is operating, information on the remaining amount of the built-in battery, information on the coupling status between the mounting unit 10 and the main body 30, etc. .

Figure 3 is a functional block diagram of the main body according to an embodiment of the present invention, and Figures 4 to 6 are diagrams showing an example of signal generation of the operation control unit according to an embodiment of the present invention.

The UV sterilizing device according to this embodiment determines irradiation of UV light depending on whether the storage space is open, and stops irradiation of UV light when the storage space is open.

For this purpose, the main body 30 includes an opening/closing detection unit 34 that determines the open/closed state of the opening/closing means, an operation control unit 35 that operates and controls the UV module 32, and a signal generation point of the operation control unit 35. It may be configured to include a count unit 36 that counts the elapsed time.

The opening/closing detection unit 34 determines the open/closed state of the opening/closing means and generates an open signal when the opening/closing means is determined to be open, and generates a close signal when the opening/closing means is determined to be in a closed state.

The open/close detection unit 34 may determine the open/closed state of the open/close means in various ways. For example, the open/close state may be determined based on the inclination value of the open/close means detected through a tilt sensor. In this way, when the opening/closing detection unit 34 is configured to determine the open/closed state based on the inclination value, the UV sterilizing device according to this embodiment is mounted on the opening/closing means of the installation object and detects the tilt sensor of the opening/closing detection unit 34. The detected inclination value can be an inclination value according to the arrangement angle of the opening and closing means. Here, a more detailed description of how the opening/closing detection unit 34 determines the open or closed state of the opening/closing means based on the inclination value will be described later with reference to FIG. 7 .

The open or closed signal generated by the open/close detection unit 34 is provided to the operation control unit 35, and the operation control unit 35 provides a UV module ( 32) can be operated and controlled.

Specifically, the operation control unit 35 may control the UV module 32 to emit UV light based on the closing signal received from the opening/closing detection unit 34. 4 as an example, the operation control unit 35 generates an irradiation start signal when receiving a closing signal from the opening/closing detection unit 34, and transmits the generated irradiation start signal to the UV module 32 and the count unit 36. can be provided to. The UV module 32 that has received the irradiation start signal starts irradiating UV light, and the count unit 36 that has received the irradiation start signal calculates the first elapsed time from the time the irradiation start signal was generated (or received). You can count. The operation control unit 35 may determine whether the first reference time (t ₁ ) has elapsed from the time of generation of the irradiation start signal based on the first elapsed time count of the counter 36. And, when it is determined that the first reference time (t ₁ ) has elapsed, the operation control unit may generate an irradiation end signal and provide it to the UV module 32. The UV module 32 that has received the irradiation end signal may end irradiation of UV light. Accordingly, when the opening/closing detection unit 34 generates a closing signal according to the closing of the opening/closing means, UV light may be irradiated from the UV module 32 for a first reference time (t ₁ ), which allows the user to close the opening/closing means. The UV sterilization device can be operated to irradiate UV light by simply closing it.

Here, the first reference time (t ₁ ) may be the time required to sufficiently sterilize the storage space and the stored items, and the set value of the first reference time (t ₁ ) may be the time at which installation of the UV sterilizing device is recommended. It may be determined by the size of the storage space, the output of the UV module 32, etc.

The operation control unit 35 may control the UV module 32 to stop irradiating UV light based on the open signal received from the opening/closing detection unit 34. To be described in detail with reference to FIG. 5, the operation control unit 35 generates an irradiation stop signal when receiving an open signal from the opening/closing detection unit 34, and sends the generated irradiation stop signal to the UV module 32 and the count unit. It can be provided in (36). The UV module 32 that has received the irradiation stop signal may stop irradiating UV light. Therefore, if the opening/closing means is opened while the UV module 32 is irradiating light, the irradiation of light from the UV module 32 is immediately stopped, thereby preventing the user from being exposed to UV light.

Meanwhile, the count unit 36 that receives the irradiation stop signal from the operation control unit 35 may count the second elapsed time from the time the irradiation stop signal was generated (or received). At this time, the count unit 36 may separately perform a first elapsed time count from the point in time when the irradiation start signal is generated and a second elapsed time count from the point in time when the irradiation stop signal is generated. The counter 36 may temporarily stop counting the first elapsed time when an irradiation stop signal is generated while counting the first elapsed time according to the irradiation start signal.

When the opened opening/closing means is closed again, the operation control unit 35 may receive a closing signal, generate an irradiation start signal, and provide the generated irradiation start signal to the UV module 32 and the count unit 36. The UV module 32, which has received the irradiation start signal, restarts the UV light irradiation that was stopped, and the count unit 36, which has received the irradiation start signal, pauses the first elapsed time count due to the opening of the opening and closing means. Can be resumed by connecting the first elapsed time count that was paused. Through this connection of the first elapsed time count, the operation control unit 35 adds up the UV light irradiation time (t ₂ ) before generating the irradiation stop signal and the time elapsed after generating the irradiation start signal again (t ₄ ). An irradiation end signal can be generated when one hour becomes the first reference time (t ₁ ).

Preferably, the count unit 36 may initialize the first elapsed time count if the irradiation start signal is not generated within the second reference time while the first elapsed time count is paused. In this case, as shown in Figure 6, even if the operation control unit 35 generates the irradiation start signal again after generating the irradiation stop signal, it generates the irradiation start signal again regardless of the UV light irradiation time before generating the irradiation stop signal. An irradiation end signal is generated when the first reference time (t ₁ ) has elapsed from a point in time. Therefore, when the storage space is opened for a relatively short period of time and UV light irradiation is stopped, the UV light irradiation time is collectively counted, thereby preventing energy consumption caused by UV light irradiation for an excessive period of time, and on the other hand, the storage space If there is a concern about recontamination of the storage space due to being open for a relatively long time, the UV light irradiation time can be reset to sufficiently sterilize the recontaminated storage space.

Here, the second reference time may be a time sufficient for the storage space to be contaminated due to the opening of the storage space, and the set value of the second reference time is the size of the storage space where installation of the UV sterilizing device is recommended, the installation of the UV sterilizing device may be determined by the usage environment of the recommended installation object, etc.

Figure 7 is a functional block diagram of an opening/closing detection unit according to an embodiment of the present invention.

Hereinafter, the opening/closing detection unit 34 according to this embodiment will be looked at in more detail with reference to FIG. 7 .

As described above, the opening/closing detection unit 34 may determine the opening/closing state based on the inclination value of the opening/closing means. To this end, the opening/closing detection unit 34 may be configured to include a tilt sensor 341 that detects a tilt value, and an opening/closing information generator 342 that generates an open or closed signal based on the tilt value.

The tilt sensor 341 is disposed within the main housing 31 to measure the tilt value. When the main housing 31 is mounted on the opening and closing means of the installation object, the tilt sensor 341 can measure the tilt value according to the opening and closing operation of the opening and closing means.

The tilt value measured by the tilt sensor 341 may be provided to the opening/closing information generator 342. The opening/closing information generator 342 generates an open or closed signal based on the tilt value provided from the tilt sensor 341, and may provide the generated open or closed signal to the operation control unit 35.

The opening/closing information generator 342 may generate an open signal when the slope value is outside a set reference range. For example, when the reference range is set from -10° to 10°, the opening/closing information generator 342 may generate an open signal when the provided tilt value is less than -10° or more than 10°.

Conversely, the opening/closing information generator 342 may generate a closing signal if the slope value is within a set reference range. However, if the installation object on which the UV sterilizing device according to this embodiment is installed is not fixed in a certain position, the measured inclination value may change as the arrangement angle of the installation object changes even if the opening and closing means is not opened or closed. For example, when the installation object is a console box of a vehicle, the measured tilt value of the tilt sensor 341 may change depending on the tilt of the vehicle body. Due to the change in inclination value due to the change in the placement angle of the installation object itself, when UV light irradiation is stopped, UV light irradiation is resumed when the placement angle of the installation object itself returns to the original angle, so it is not a big problem, but the placement of the installation object itself If UV light irradiation starts due to a change in inclination value due to an angle change, UV light may be irradiated while the opening/closing means is open, and there is a risk that the user may be exposed to UV light. To solve this problem, the opening/closing information generator 342 may generate a closing signal when the change in slope value per unit time is greater than or equal to the reference change value and the final slope value is within the reference range. That is, the opening/closing information generation unit 342 generates a closing signal to irradiate UV light only when the user operates the opening/closing means to open/close the opening/closing means and is accompanied by a relatively rapid change in the inclination value, and causes the inclination of the installation object unintentional by the user. When the slope value falls within the standard range due to a gradual change in slope, a closing signal is not generated and UV light may not be irradiated.

Additionally, depending on the type and shape of the installation object, the tilt value measured in the closed state of the opening and closing means may vary. For example, the opening and closing means disposed on the upper side may measure a tilt value close to horizontal in a closed state, but the opening and closing means disposed on the front side may measure a tilt value close to vertical in a closed state. In order to install and use the UV sterilizing device according to the present embodiment on various types of installation objects, the installation angle of the UV sterilizing device It is desirable to vary depending on .

To this end, the opening/closing detection unit 34 may be provided with a reference range setting unit 343 that flexibly sets the reference range depending on the installation environment.

The reference range setting unit 343 determines whether the opening and closing means is closed based on the amount of change in the slope value measured when the main body unit 30 is mounted on the mounting part 10, and determines whether the opening and closing means is closed and determines the slope value measured in the closed state. The standard range can be set using the standard range setting unit 343. More specific details regarding the standard range setting process of the standard range setting unit 343 will be described later with reference to FIG. 10.

FIG. 8 is a functional block diagram showing a configuration for mode selection of the main body according to an embodiment of the present invention, FIG. 9 is a functional block diagram of a coupling detection unit according to an embodiment of the present invention, and FIG. 10 is a functional block diagram of a coupling detection unit according to an embodiment of the present invention. This is a diagram illustrating an example of mode selection by a mode selection unit according to an embodiment of.

The UV sterilizing device according to this embodiment does not irradiate UV light when the main body 30 is not coupled to the mounting part 10, so that in the uninstalled state of the main body 30 (unattached to the mounting part), UV light can be prevented from being irradiated.

To this end, the UV sterilizing device according to this embodiment includes a coupling detection unit 37 that determines whether the mounting part 10 and the main body 30 are coupled, and a mode selection unit 38 that selects the operating mode of the UV sterilizing device. ) may be configured to include.

The coupling detection unit 37 may determine the coupling or separation state between the mounting unit 10 and the main body 30 and provide determination information to the mode selection unit 38. For this purpose, the coupling detection unit 37 receives detection information from the coupling detection sensor 371, which detects proximity or contact between the mounting part 10 and the main body 30, and the coupling detection sensor 371, and connects the mounting part 10 to the coupling detection sensor 371. ) may be provided with a coupling state determination unit 372 that determines the coupling state or separation state between the main body portion 30.

The coupling detection sensor 371 is disposed on the main body 30 and can detect the approach of the mounting part 10 to the main body 30 or the contact between the mounting part 10 and the main body 30. Various types of sensors may be applied as the coupling detection sensor 371, but as described above, when at least a portion of the mounting portion 10 is made of a magnetic material, the coupling detection sensor 371 is a Hall sensor applied to the mounting portion 10. Magnetism can be detected upon approach. And the coupling state determination unit 372 determines the coupling state when the coupling detection sensor 371 detects the magnetism of the mounting part 10, and determines the coupling state to be in a separated state when the coupling detection sensor 371 does not detect the magnetism of the mounting part 10. It can be judged as follows. In this way, the coupling determination using the Hall sensor can prevent the approach or contact of a non-magnetic object from being mistakenly judged as a coupling between the mounting part 10 and the main body 30.

Meanwhile, the mode selection unit 38 may select one mode from a plurality of modes including standby mode based on the determination of the coupling state determination unit 372. Here, the operating mode of the UV sterilizing device according to this embodiment may include standby mode and normal mode. In the standby mode, the operation control unit 35 may not control the operation of the UV module 32 and the UV module 32 may not irradiate UV light. Conversely, in the normal mode, operation control of the operation control unit 35 or UV light irradiation of the UV module 32 may be performed.

Preferably, the UV sterilizing device according to the present embodiment may be equipped with a battery that supplies power in a different configuration, and in standby mode, the power supply to the operation control unit 35 and UV module 32 is cut off, and in normal mode, the power supply to the operation control unit 35 and the UV module 32 is blocked. The power supply to the operation control unit 35 and the UV module 32 can be unblocked. At this time, power may be supplied to the coupling detection unit 37 and the mode selection unit 38 at all times regardless of the mode.

The mode selection unit 38 can select the standby mode when the coupling state determination unit 372 determines the disconnection state. Additionally, the mode selection unit 38 can select the normal mode when the coupling state determination unit 372 determines that the coupling state is in the coupling state. However, if the coupling state determination unit 372 switches to the normal mode immediately upon determining the coupling state, when the main body 30 is coupled to the mounting portion 10 while the UV light irradiation conditions are met, UV light is immediately irradiated to the user. may be exposed to UV light. Therefore, preferably, as shown in FIG. 10, when the coupling state determination unit 372 determines the coupling state, the mode selection unit 38 can select the normal mode after a predetermined delay time (t ₆ ).

At this time, when the operation control unit 35 generates the irradiation end signal, the mode selection unit 38 selects the standby mode for a third reference time from the time the operation control unit 35 generates the irradiation end signal and then selects the standby mode for the third reference time. After this has elapsed, you can select normal mode again. Therefore, when the UV light irradiation is sufficiently completed and the operation control unit 35 generates an irradiation end signal, the opening and closing means is opened and closed during the third reference time and the UV light is not irradiated even if the UV light irradiation condition is met, resulting in meaningless UV light. Power consumption due to light irradiation can be prevented. Here, the third reference time may be the same as the second reference time, and if necessary, the third reference time may be a time different from the second reference time.

Meanwhile, as described above, the reference range setting unit 343 determines whether the opening and closing means is closed based on the change in the slope value measured when the main body unit 30 is mounted on the mounting unit 10, and determines whether the opening and closing means is closed. You can set the reference range using the slope value measured in .

Specifically, the reference range setting unit 343 may set the reference range based on the slope value during the delay time before the mode selection unit 38 selects the general mode. Preferably, the reference range setting unit 343 monitors the change in the slope value detected during the delay time, and if the slope value changes above the reference value and then stabilizes and shows a change below the reference value, the reference range setting unit 343 monitors the change in the slope value detected during the delay time. The average slope value can be calculated. And the reference range can be set based on the calculated average slope value. For example, if the average slope value is 15°, the range from 10° to 20° can be set as the reference range. Therefore, if the user couples the main body 30 to the mounting part 10 mounted on the opening and closing means and closes the opening and closing means within the delay time (t ₆ ), the standard is based on the average value of the inclination detected while the opening and closing means is closed.
