Includes. In addition, "including" a certain component means that other components may be further included rather than excluding other components unless otherwise stated.

Referring to FIG. 1, the ultraviolet sterilization module assembly for mounting furniture of the present invention includes a module body 10 made of wood (solid wood) and a power connection part 40 for supplying power to the module body 10.

Specifically, the module body 10 may be composed of a rectangular wooden box. That is, when the module main body 10 is made of wood such as solid wood, when it is installed inside furniture such as a drawer of a desk, there is little sense of foreignness, and thus it can be applied more eco-friendly.

On the other hand, a first ultraviolet irradiation portion 11a and a second ultraviolet irradiation portion 11b are formed on the upper surface of the module body 10, and an illuminance sensor 12 is installed in the middle thereof. In addition, a first fixing portion 13 and a second fixing portion 14 are formed at both ends of the module body 10 by a predetermined length and formed symmetrically to each other. Here, in the first fixing part 13 and the second fixing part 14, a first mounting hole 13h and a second mounting hole 14h through which a bolt passes are respectively formed.

In addition, the module body 10 is provided with an operation display unit 20 so as to display the operating states of the first and second ultraviolet irradiation units 11a and 11b on the outside of the furniture. In addition, an on-off switch unit 30 for driving the module body 10 is provided when pressed by an external force. The on-off switch unit 30 is turned on by applying power to the inside by pressing the terminal of the on-off switch unit 30 when a pressing force is applied by contacting the sidewall when opening/closing a drawer or furniture. State.

Meanwhile, a panel mount part 45 is provided on the module body 10, and the panel mount part 45 is connected to the power connection part 40. That is, in this embodiment, a method in which power is provided by wire is illustrated. However, the present invention is not limited thereto, and a charging power supply unit (a USB charging type power supply unit) is provided in the module body 10 of the present invention, so that the panel mount unit 45 and the power connection unit 40 may be excluded.

In this way, the operation display unit 20, the on-off switch unit 30, and the panel mount unit 45 connected to the power connection unit 40 are each connected to the module body 10 through a cable, and these elements are designed It can be installed in the state of being exposed to the outside or inserted into the main part of the furniture considered in the image

Referring to FIG. 2, on the upper surface of the module body 10, a first ultraviolet irradiation portion 11a and a second ultraviolet irradiation portion 11b are respectively formed on both sides of the illuminance sensor 12 in the center.

Here, the UV irradiation units 11a and 11b may be applied with a UV-C LED that irradiates a super sterilization ray having a wavelength range of about 100 nm to 280 nm of UV-C. Accordingly, it is possible to efficiently kill Escherichia coli remaining in the stored cell phone or other items, staphylococcus aureus, Vibrio bacteria, Salmonella, botulinum mycosis pathogenic bacteria and general bacteria, which are bacteria that cause food poisoning.

In addition, the illuminance sensor 12 is used to automatically operate the ultraviolet irradiation units (11a, 11b) by detecting when a mobile phone or other items are stored in a storage space such as a drawer.

Meanwhile, the fixing portions 13 and 14 protruding from both ends of the module body 10 of the present invention are formed at positions that are displaced from each other in the longitudinal direction, and only part of the module body 10 protrudes to both sides. Accordingly, when a plurality of module bodies 10 are installed in series or in parallel, they can be installed in close contact with each other, thereby minimizing the installation space.

3 and 4, the module body 10 has a mounting area 10b having a predetermined space therein so that the PCB 50 can be inserted therein, and a cover plate on the top of the mounting area 10b (10a) is detachably mounted. Accordingly, it is possible to improve maintenance performance after installation. That is, the module body 10 of the present invention is made of solid wood, and the cover plate 10a is provided in a structure detachably installed on the cupber mounting portion 16 of the module body 10 in order to improve maintainability. In addition, as shown in FIG. 3, an interface terminal portion 55 is provided on the PCB 50, and an operation display portion 20, an on-off switch portion 30, and a panel mount portion 45 are respectively provided through the interface terminal portion 55. It is electrically connected.

Referring to FIG. 5, a circular concave region 15b is formed on the lower surface of the module body 10 (lower surface with reference to FIG. 5). This recessed region 15b serves to allow the ultraviolet irradiation portion 11b to be positioned inside the module body 10 without protruding to the outside. Here, the groove area 15b is formed as a groove having a certain inclination so as not to interfere with the irradiation angle (approximately 120 degrees) of, for example, a UV-C LED.

Referring to FIG. 6, the ultraviolet sterilization module assembly of the present invention having the above-described configuration can be easily installed, for example, through fixing bolts B1 and B2 on the lower surface of the upper plate 100 of the desk. That is, in the present invention, the module body 10 can be conveniently installed in various locations of existing furniture.

In addition, in the present invention, when the mobile phone P is stored in the drawer 200, the illuminance sensor 12 detects it and drives a plurality of ultraviolet irradiation units 11a and 11b through the control unit to remain in the mobile phone P. It can kill bacteria or viruses. In this case, it goes without saying that the UV irradiation time and period of the UV irradiation units 11a and 11b can be adjusted and applied according to a required sterilization setting. For example, the UV sterilization operation can be set to be about 5 minutes and then turned off by operation.

In addition, the ultraviolet sterilization operation may be applied in parallel with an optical sensor detection mode using the illuminance sensor 12 or an external switch mode using the on/off switch 30. For example, when power is first applied, the optical sensor sensing mode is operated, and when the on-off switch unit 30 is operated thereafter, the operation can be set in the switch mode thereafter.

As another example, since it operates according to the illuminance in the optical sensor detection mode, in this case, a separate external switch (on-off switch unit) can be excluded, and when the illuminance is lowered (when it becomes dark) through the illuminance sensor 12 The sterilization mode can be turned on and then controlled to turn off the sterilization mode when it becomes bright again. In addition, in this case, when an on signal is received from the external on/off switch unit 30, the on/off setting may be possible regardless of the detection signal of the illuminance sensor 12. In addition, the operation display unit 20 may notify the user of the operation state by turning on such an on/off setting.

Meanwhile, in the present embodiment, the mobile phone sterilization has been described as an example, but it goes without saying that the same sterilization treatment is also possible for various items stored in the drawer part 200.

Referring to FIG. 7, as a second embodiment, a UV-C LED 11C having a wavelength range of 100 to 280 nm and a UV-A LED 11A having a wavelength range of 320 to 405 nm inside the module body 10 Each is provided in a provided form. In this case, the on-off switch unit 30 may be operated to control the on-off of the UV-A LED 11A, and to control the on-off of the UV-C LED 11C through the illuminance sensor 12.

That is, in general, the wavelength of UV-C is made in the range of 100 to 280 nm, and generally has the greatest sterilization power (DNA destruction power) in the 265 nm band, but it is harmful to the human body and has a problem of large power consumption. On the other hand, the wavelength of UV-A is made in the range of 320 ~ 405nm, of which, in the 405nm band, it reacts with porphyrin contained in bacteria and decomposes. However, UV-A should be irradiated continuously for a long time (10 to 20 hours) instead of low power consumption.

Accordingly, in the present embodiment, the UV-A LED 19b is turned on and off from the outside through the on-off switch unit 30 to sterilize the storage room (drawer unit) 200 for a long time. In this case, it is possible to intuitively recognize that the inside of the drawer part 200 is being sterilized from the outside by configuring the front of the storage room with a transparent material.

On the other hand, by turning on and off the UV-C LED 11C through the illuminance sensor 12, the illuminance sensor 12 recognizes this when the user stores items such as mobile phones P in the drawer 200 and closes the drawer. Thus, sterilization and disinfection are performed by driving the UV-C LED (11C) for about 1 to 2 minutes. In addition, although not shown, the module body 10 is composed of a plurality, of which a plurality of UV-C LEDs (11C) are provided in one module body, and a plurality of UV-A LEDs (11A) are provided in the other module body. It is also possible to configure and control in the manner described above.

Accordingly, while reducing power consumption required for sterilization, UV-C irradiation, which is harmful to the human body, can be controlled to be driven only when the drawer 200 is closed, so that safer sterilization and sterilization can be achieved.

Referring to FIG. 8, according to the third embodiment of the present invention, a sterilization module may be applied to the open drawer part 200.

Specifically, the drawer part 200 may include an open-type drawer part 200 having a sunshade plate 22 formed thereon and a base plate 260 formed in the lower part thereof. Here, a PCB is installed between the sunshade plate 220 and the base plate 260 in an erect state. On this PCB, a UV-C LED (11C) is installed at the top, and a UV-A LED (11A) is installed at the bottom with the partition wall 250 interposed therebetween.

In addition, the driving unit 300 is provided on the rear surface of the PCB, and the refractive lens 400 is installed in a vertical direction in front of the partition wall 250 in a state in which the refractive lens 400 is erected. Here, the refractive lens 400 is installed in a state erected on the base plate 260 by the installation block 450.

Through this configuration, the ultraviolet rays irradiated from the UV-C LED 11C installed on the upper side of the PCB are refracted downward through the refractive lens 400. Accordingly, a UV-C irradiation area of a certain range is formed on the base plate 260. Accordingly, even if the open drawer part 200 is configured, it is possible to prevent UV-C from being irradiated to the outside and causing harm to the human body.

Meanwhile, the UV-A LED 11A acts to destroy bacteria through reaction and decomposition of porphyrin by continuously irradiating UV with a wavelength of 405 nm.

In this way, by controlling the irradiation angle of UV-C, which is harmful to the human body, to irradiate it within 1 minute, it prevents harm to the human body when in use, and by continuously irradiating the UV-A installed under the base plate 260 to visible light. By doing so, users can recognize that they are in good hygiene conditions, and bacteria can be removed when irradiation is performed for a long time.

Referring to FIG. 9, according to the fourth embodiment of the present invention, a concave reflective plate 600 may be installed on a lower surface of the sunshade plate 220 in addition to the refractive lens 400 described above as a refractive means. That is, when UV light is refracted with a refractive lens, it may be difficult to secure a desired wavelength band. Therefore, by installing the concave reflector 600 to which the metal reflective coating is applied, the angle of refraction can be more easily adjusted.

In addition, when the wireless charging unit 500 is installed on the base plate 260 and the mobile phone P is placed on the wireless charging unit 500, charging, sterilization, and sterilization may be performed in parallel.

In the above, the present invention has been illustrated and described with respect to specific embodiments, but the present invention is not limited to the above-described embodiments, and those of ordinary skill in the art to which the present invention pertains, the present invention described in the following claims.
