Description

UV sterilization device that is easy to attach and remove {UV Sterilizer}

The present invention relates to a UV sterilization device that is easily attachable and detachable, and more specifically, to a UV sterilizing device that is easily attached and detachable, and has a mounting part that is mounted in a storage space of an installation object, and a main body part that is detachably coupled to the mounting part and capable of irradiating UV light. It makes it easy to attach and detach the part, and when the mounting part and the main body are combined, the hanging area where the hanging hook of the mounting part is caught has elasticity in the insertion/removal direction of the hanging hook, so that the force applied to the catching area during the insertion/removal of the hanging hook is reduced. It relates to a UV sterilizing device that prevents damage to the caught area by allowing it to be absorbed by its elasticity.

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, storage space (accommodation space) of target products to which UV sterilization device is not applied during production, such as "portable sterilization device using UV LED" (hereinafter referred to as 'conventional patent') disclosed in Patent Publication No. 10-2015-0028154 ) A sterilizing device that the user can install and sterilize at will is being developed.

However, since the conventional patent is used without separate fixation in the storage space, there is a problem that it is difficult to keep the UV light irradiation direction constant when used on an object such as a vehicle console box that may be shaken. Conversely, when using a fixing means such as double-sided tape to fix the UV sterilizing device in the receiving space, there is a problem that management of the UV sterilizing device, such as battery replacement, battery charging, and removal of foreign substances, is inconvenient.

The main body 10 can be separated from the mounting part 30 through .

An engraved area 112 having a shape corresponding to the mounting part 30 may be disposed on the coupling surface of the main housing 11 to accommodate the mounting part 30. Therefore, in a state where the main body 10 is coupled to the mounting part 30, the mounting part 30 is accommodated and arranged in the engraved area 112 of the main body housing, and the main body 10 coupled with the mounting part is arranged in close contact with the wall of the receiving area.

Figure 6 is a diagram showing the catching hook according to an embodiment of the present invention being inserted through the insertion area, and Figure 6 is a diagram showing the catching hook according to an embodiment of the present invention being arranged to be caught in the catching area, and Figure 7 is a drawing showing the catching hook according to an embodiment of the present invention. This is a diagram showing how force is applied to the catching area during the process of inserting the locking protrusion into the protrusion groove according to one embodiment. And Figure 8 is a diagram showing the force applied to the catching area in the process of inserting the catching hook according to an embodiment of the present invention through the insertion area.

Hereinafter, the insertion locking portion 111 of the main body portion and the locking hook 32 of the mounting portion will be examined in more detail with reference to FIGS. 3 to 9.

The insertion locking portion 111 includes an insertion area 1111 formed through the coupling surface of the main body housing 11 so that the locking hook 32 can be inserted into the internal space of the main body housing, and an insertion area 1111 inserted into the insertion area 1111. It may be configured to include a locking area 1112 that prevents the locking hook 32 moved to one side from being caught and the coupling between the main body 10 and the mounting portion 30 from being released arbitrarily.

The hanging hook 32 protrudes from one end of the mounting plate 31 in the downward direction (opposite direction of the mounting surface), and the protruding end is bent in one direction (horizontal to the mounting plate) to form an 'ㄴ' shape. You can.

Looking at the coupling process between the inserting hook 32 and the locking portion 111, first, as shown in FIG. 5, the hook 32 is inserted into the inner space of the main body housing through the insertion area 1111 of the locking portion. You can. In this way, when the catching hook 32 is moved in the direction of the catching area 1112 in the state of inserting the catching hook 32 into the internal space, the catching hook 32 is caught in the catching area 1112 as shown in FIG. The coupling between (10) and the mounting portion (30) can be maintained. At this time, the catching area 1112 may be provided with a locking protrusion 1112a that protrudes toward the internal space, and the hook 32 may be provided with a protrusion groove 321 into which the locking protrusion 1112a can be inserted. The locking protrusion 1112a is inserted into the protrusion groove 321 while the locking hook 32 is disposed in the locking area 1112, so that a greater force is required to move the locking hook 32 in the unlocking direction. . Therefore, it is possible to prevent the latching hook 32 from arbitrarily moving in the latching direction.

At this time, in the process of inserting or removing the catching protrusion 1112a from the protrusion groove 321, the catching hook 32 or the catching area 1112 must move up and down a predetermined distance. To this end, the catching hook 32 or the catching area 1112 may have elasticity in the up and down directions.

Referring to FIG. 4, the front and rear end connection portions connected to the hook 32 at one end of the mounting plate 31 are formed so that elasticity is formed in the hook 32 in the vertical direction (thickness direction of the mounting plate). An elasticity providing hole 311 may be disposed. The elasticity providing hole 311 separates a portion of the circumference of the connection between the latching hook 32 and the mounting plate 31 from the main body of the mounting plate 31, thereby allowing the latching hook 32 to have elasticity in the vertical direction. Due to this elasticity, the locking hook 32 can move up and down at a predetermined height when the locking protrusion 1112a is inserted into/detached from the protrusion groove 321, as shown in FIG. 7 . In addition, the elasticity of the catching hook 32 is such that, as shown in FIG. 8, the catching area 1112 is inserted into the internal space through the insertion area 1111 or is removed from the internal space. When the locking areas 1112 come into contact with each other, damage to the locking hook 32 or the locking area 1112 can be prevented by absorbing some of the force applied to each other due to the contact.

Referring to FIG. 3, so that the locking area 1112 has a predetermined elasticity in the vertical direction, the insertion locking part 111 has an elasticity providing area 1113 formed through the main body housing coupling surface along a partial section around the locking area. can be provided. At this time, the insertion area 1111 and the elasticity providing area 1113 are connected to each other, so that the elasticity of the part of the catching area 1112 that is close to the insertion area 1111 can be formed to be greater. Due to this elasticity, the locking area 1112 can move up and down at a predetermined height when the locking protrusion 1112a is inserted into/detached from the protrusion groove 321, as shown in FIG. 7 . In addition, the elasticity of the catching area 1112 is such that, as shown in FIG. 8, the catching area 1112 is inserted into the internal space through the insertion area 1111 or in the process of being removed from the internal space, the catching hook 32 and the When the locking areas 1112 come into contact with each other, damage to the locking hook 32 or the locking area 1112 can be prevented by absorbing some of the force applied to each other due to the contact. In the process of inserting or removing the catching protrusion from the protrusion groove, the catching area may move in the up and down direction due to elasticity.

Figure 9 is a functional block diagram of the main body according to an embodiment of the present invention, and Figures 10 to 12 are diagrams showing an example of signal generation of the operation control unit according to an embodiment of the present invention. And Figure 13 is a diagram showing an example of mode selection by the mode selection unit according to an embodiment of the present invention.

The installation object on which the UV sterilizing device according to an embodiment of the present invention is installed may be provided with an opening and closing means, and the accommodation space of the installation object may be opened or closed according to the opening and closing operation of the opening and closing means. For example, installation objects may include a vehicle console box, vehicle glove box, closet, trash can, toilet, etc.

At this time, the UV sterilizing device according to this embodiment determines irradiation of UV light depending on whether the storage space is open, and can stop irradiation of UV light when the storage space is open.

For this purpose, the main body 10 includes an open detection unit 17 that detects whether the installation object storage space is open, an operation control unit 16 that operates and controls the UV module 12, and a signal from the operation control unit 16. It may be configured to include a count unit 18 that counts the elapsed time from the point of creation.

The open detection unit 17 determines the open or closed state of the storage space and generates an open signal when the storage space is determined to be open, and generates a closed signal when the storage space is determined to be closed.

The open detection unit 17 can determine the open or closed state of the storage space in various ways. For example, the open detection unit 17 measures the tilt of the opening and closing means using a separate tilt sensor, and measures If the inclination value of one opening and closing means is outside a predetermined standard range, the storage space is determined to be open. However, if the measured inclination value is within the standard range, the storage space can be determined to be closed. In addition, the open detection unit 17 measures the amount of light received in the storage space using a separate light detection sensor, and if the measured light received amount value of the storage space exceeds the standard value, it determines that the storage space is open. If the value is below the standard value, it can be determined that the storage space is closed.

Depending on whether the storage space is determined to be open or closed, the open or closed signal generated by the open detection unit 17 is provided to the operation control unit 16, and the operation control unit 16 receives the signal received from the open detection unit 17. The UV module 12 can be controlled to operate based on an open or closed signal.

Specifically, the operation control unit 16 may control the UV module 12 to emit UV light based on the closing signal received from the open detection unit 17. 10 as an example, the operation control unit 16 generates an irradiation start signal when receiving a closing signal from the open detection unit 17, and sends the generated irradiation start signal to the UV module 12 and the count unit 18. can be provided to. The UV module 12 that has received the irradiation start signal starts irradiating UV light, and the count unit 18 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 16 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 18. 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 12. The UV module 12 that has received the irradiation end signal can end irradiation of UV light. Accordingly, when the open detection unit 17 generates a closing signal according to the opening and closing means, UV light may be irradiated from the UV module 12 for the first reference time (t ₁ ), which allows the user to close the opening and 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 can be determined by the size of the storage space, the output of the UV module 12, etc.

The operation control unit 16 may control the UV module 12 to stop irradiating UV light based on the opening signal received from the opening detection unit 17. To be described in detail with reference to FIG. 11, the operation control unit 16 generates an irradiation stop signal when receiving an open signal from the open detection unit 17, and sends the generated irradiation stop signal to the UV module 12 and the count unit. It can be provided in (18). The UV module 12 that has received the irradiation stop signal may stop irradiating UV light. Accordingly, when the opening and closing means is opened while the UV module 12 is irradiating light, and the storage space is opened, the irradiation of light from the UV module 12 is immediately stopped, thereby preventing the user from being exposed to UV light.

Meanwhile, the count unit 18 that receives the irradiation stop signal from the operation control unit 16 may count the second elapsed time from the time the irradiation stop signal is generated (or provided). At this time, the count unit 18 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 18 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 and closing means is closed again and the storage space is closed, the operation control unit 16 receives the closing signal, generates an irradiation start signal, and provides the generated irradiation start signal to the UV module 12 and the count unit 18. . The UV module 12, which has received the irradiation start signal, restarts the UV light irradiation that was stopped, and the count unit 18, 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 16 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, as shown in FIG. 12, the pause time (t ₅ ) from the time when the count unit 18 pauses the first elapsed time count to the time when the irradiation start signal is generated is set to the second reference time. If it is exceeded, the first elapsed time count may be initialized. In this case, the operation control unit 16 initializes the first elapsed time count even if the irradiation start signal is generated again after generating the irradiation stop signal, so it generates the irradiation start signal again regardless of the UV light irradiation time before generating the irradiation stop signal. The irradiation end signal is generated when the first reference time (t ₁ ) has elapsed from the point of generation. 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.

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

To this end, the UV sterilizing device according to this embodiment may be configured to include a mode selection unit 19 that selects the operating mode of the UV sterilizing device based on whether the binding detection unit 14 detects the binding.

As described above, the coupling detection unit 14 can detect whether the mounting unit 30 and the main body unit 10 are coupled. The coupling detection unit 14 generates coupling information when coupling between the mounting unit 30 and the main body 10 is detected, and generates separation information when detection of coupling between the mounting unit 30 and the main body 10 stops. And the generated combination information and separation information can be provided to the mode selection unit 19.

The mode selection unit 19 may select one mode based on the combination information or separation information provided from the combination detection unit 14.

Here, the operating mode of the UV sterilizing device according to this embodiment may include standby mode and normal mode. In standby mode, the operation control unit 16 may not control the operation of the UV module 12 and the UV module 12 may not irradiate UV light. Conversely, in the normal mode, operation control of the operation control unit 16 or UV light irradiation of the UV module 12 may be performed.

Preferably, the UV sterilizing device according to the present embodiment may be equipped with batteries that supply power in different configurations, and in standby mode, the power supply to the operation control unit 16 and UV module 12 is cut off, and in normal mode, The power supply to the operation control 16 and the UV module 12 can be unblocked. At this time, power may be supplied to the coupling detection unit 14 and the mode selection unit 19 at all times regardless of the mode.

The mode selection unit 19 can select the standby mode when it receives separation information from the coupling detection unit 14. Additionally, the mode selection unit 19 can select a normal mode when it receives combination information from the combination detection unit 14. However, when the coupling detection unit 14 detects the coupling between the main body 10 and the mounting unit 30 and immediately switches to the normal mode, the UV light irradiation conditions are met (for example, determining the closed state of the storage space). When the main body part 10 is coupled to the mounting part 30, UV light is immediately irradiated and the user may be exposed to UV light. In order to solve this problem, preferably, as shown in FIG. 13, when coupling information is provided from the coupling detection unit 14, the mode selection unit 19 selects the normal mode after a predetermined delay time (t ₆ ). You can.

At this time, when the operation control unit 16 generates the irradiation end signal, the mode selection unit 19 selects the standby mode for a third reference time from the time the operation control unit 16 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. Accordingly, when the UV light irradiation is sufficiently completed and the operation control unit 16 generates an irradiation end signal, the storage space is opened and closed during the third reference time and the UV light is not irradiated even if the UV light irradiation conditions are met, resulting in Power consumption due to meaningless UV 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.
