Background Art

[0002] Conventionally, in restaurants, hospitals, amusement arcades, and various other facilities, cleaning, disinfection, etc. within the facilities have been regularly carried out for hygiene purposes. For example, on the doorknobs that are frequently touched by users' hands, miscellaneous bacteria are likely to breed, and leaving it in that state is a hygienic problem. Therefore, an ultraviolet irradiation device is arranged adjacent to the doorknob to automatically disinfect the doorknob with ultraviolet rays (see Patent Document 1).

[0003] On the other hand, for the disinfection of users' hands in facilities, currently, spraying and applying alcohol is being done. Therefore, alcohol sprays are often placed at the entrances of facilities. In order to manage the disinfection of fingers using alcohol, an administrator is placed at the entrance, and the administrator sprays alcohol spray on the users' hands to permit entry into the facility.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0025] FIGS. 1 and 2 show the overall configuration of the ultraviolet sterilization device 1 for fingers according to the first embodiment of the present invention. The ultraviolet sterilization device 1 for fingers includes a first irradiation unit 110 and a second irradiation unit 210 that constitute an irradiation unit, a holding unit 150 that holds the first irradiation unit 110 and the second irradiation unit 210, a detection unit 180 that detects the insertion of a finger, a power supply 185, and a control device 190.

[0026] The first irradiation unit 110 houses the first ultraviolet lamp 120 therein and irradiates the first ultraviolet rays of the first ultraviolet lamp 120. The second irradiation unit 210 houses the second ultraviolet lamp 220 therein and irradiates the second ultraviolet rays of the second ultraviolet lamp 220.

[0027] The detailed structure of the first irradiation unit 110 will be described with reference to FIG. 3. Since the second irradiation unit 210 has the same structure, the description of the second irradiation unit 210 will be omitted by making the last two digits of the reference numerals of the components and members of the first irradiation unit 110 the same.

[0028] The first irradiation unit 110 includes a first ultraviolet lamp 120, a first ballast 122 that supplies an alternating current to the first ultraviolet lamp 120, a first housing 124 that houses the first ultraviolet lamp 120, a first opening 124A for irradiation formed in the first housing 124, a guard portion 126 installed in the first opening 124A, and a reflection plate 128 disposed behind the first ultraviolet lamp 120 within the first housing 124.

[0029] The first ultraviolet lamp 120 emits ultraviolet rays with a wavelength of 253.7 nanometers, which are most easily absorbed by pathogenic bacteria such as viruses. The first ultraviolet lamp 120 includes a cylindrical glass tube, electrodes disposed near both ends inside the glass tube, and caps fixed to both ends of the glass tube. When the first ultraviolet lamp 120 is mounted on a socket and a current is passed through the electrodes, electrons are emitted from the emitters (electron-emitting substances) of the electrodes and are attracted and move to the opposite electrodes. The moving electrons collide with mercury atoms enclosed in the glass tube, and ultraviolet rays are emitted.

[0030] The first housing 124 has a box shape close to a hexahedron, and a detachable lid 125 is provided on one of the six faces (this face is defined as the ultraviolet irradiation plane). A first opening 124A is formed in the lid 125. An internal first ultraviolet lamp 120 faces the first opening 124A. As shown in Fig. 3(B) with the lid 125 removed, the reflection plate 128 is arranged on the opposite side of the first opening 124A in the first ultraviolet lamp 120. As a result, a part of the first ultraviolet rays irradiated from the first ultraviolet lamp 120 is directly emitted from the first opening 124A. The remaining part of the first ultraviolet rays is reflected by the reflection plate 128 and then emitted from the first opening 124A. In this embodiment, the direction perpendicular to the plane of the opening 124A is defined as the irradiation direction 129 of the first ultraviolet rays.

[0031] The guard part 126 is installed to cover the first opening 124A. In this embodiment, the guard part 126 is composed of a metal mesh member, which prevents the user's hand from contacting the first ultraviolet lamp 220. Note that the material of the guard part 126 is not limited to the metal mesh member, and a fence member formed by arranging a plurality of linear wires in parallel, a punching metal member having a large number of small apertures, an ultraviolet transmissive material such as glass or resin that can transmit ultraviolet rays, etc. can also be used.

[0032] The first opening 124A is rectangular. The size of the longitudinal direction LK1 of the first opening 124A is set to be 200 mm or more and 600 mm or less, and the size of the short transverse direction LW1 is set to be 150 mm or more and 350 mm or less. Thereby, the first ultraviolet rays can be collectively irradiated onto the palms or the backs of both hands. In conjunction with this, the size of the longitudinal direction LC1 of the plane in the first housing 14 where the first opening 124A is formed is set to be 220 mm or more and 620 mm or less, and the size of the short transverse direction LW1 is set to be 170 mm or more and 370 mm or less.

[0033] As shown in FIG. 2, the holding unit 150 holds the first irradiation unit 110 and the second irradiation unit 220 with a space therebetween. The holding unit 150 includes a holding plate 152 to which the first irradiation unit 110 and the second irradiation unit 220 are fixed, and a connection case 154 provided integrally on the back side of the holding plate 152. The connection case 154 has a substantially triangular shape when viewed from the side, and the holding plate 152 is provided on the inclined surface 154C thereof. As shown in FIG. 4(A), the bottom surface 154A of the connection case 154 can be connected to a step ladder 160 or a pedestal, and as shown in FIG. 4(B), the back surface 154B can be connected to a wall surface or the like. Further, a power supply 185 for supplying a desired alternating voltage to the first irradiation unit 110 and the second irradiation unit 220 and a control device 190 for controlling irradiation and the like of the first irradiation unit 110 and the second irradiation unit 220 are housed in the connection case 154.

[0034] Returning to FIG. 2, the first irradiation unit 110 and the second irradiation unit 220 held by the holding unit 150 are in a posture in which the first irradiation direction 129 of the first ultraviolet ray and the second irradiation direction 229 of the second ultraviolet ray face each other. In other words, the first opening 124A of the first irradiation unit 110 faces the second opening 224A of the second irradiation unit 220. Further, a gap formed by the first irradiation unit 110 and the second irradiation unit 220 serves as an insertion space 170 for inserting a finger.

[0035] As shown in FIG. 5, the distance WU between the closest edges of the first ultraviolet lamp 120 and the second ultraviolet lamp 220 is 70 mm or more and 200 mm or less. As a result, the distance to the midpoint between them is 35 mm or more and 100 mm or less, and a sufficient sterilization effect can be exhibited in a short time (for example, 10 seconds or less, preferably 8 seconds or less). If the distance is increased further, it is necessary to lengthen the irradiation time, resulting in a long waiting time when used at the entrance of a facility where many people enter and leave.

[0036] Considering the insertion space 170 defined by the first opening 124A and the second opening 224A, the distance WS in the opposing direction of this insertion space 170 is 60 mm or more and 180 mm or less, preferably 70 mm or more and 150 mm or less. By setting it to 60 mm or more, it becomes possible for the user to change the insertion angle of the hand H within the insertion space 170, and further, contact of the hand H with the guard portion 126 can be suppressed.

[0037] Furthermore, the insertion depth DS in the insertion space 170 (that is, the distance from the finger insertion port 170A to the holding plate 152) is set to 170 mm or more and 370 mm or less. By doing so, the entire hand H of the user can be arranged within the insertion space 170. On the other hand, since this insertion depth DS is not too deep, even if the distance WS in the opposing direction of the insertion space 170 is set small, for example, to 120 mm or less, contact of the wrist or upper arm with the finger insertion port 170A (the first irradiation portion 110 and the second irradiation portion 220) can be suppressed. Incidentally, the insertion depth DS is preferably 300 mm or less, more preferably 250 mm or less.

[0038] Also, the angle α in the opposing direction (the first irradiation direction 129 or the second irradiation direction 229) of the first irradiation portion 110 and the second irradiation portion 220 is set to 10° or more and 80° or less with respect to the horizontal, preferably 30° or more and 60° or less. In the present embodiment, it is set to 45°, which is 40° or more and 50° or less. Of course, the angle α can also be set to 0° or 90°.

[0039] The insertion space 170 has a finger insertion port 170A for inserting a finger defined in a strip shape (slit shape or rectangular shape) on its upper side. This finger insertion port 170A is the upper edge (lip) of the plane in which the first opening 124A of the first irradiation unit 110 is formed and the upper edge (lip) of the plane in which the second opening 224A of the second irradiation unit 120 is formed. The angle β in the width direction WE of this finger insertion port 170A is set to be 10° or more and 80° or less with respect to the horizontal, preferably 30° or more and 60° or less. In this embodiment, it is set to 45° which is 40° or more and 50° or less. In this embodiment, the longitudinal direction LE of the strip of the finger insertion port 170A is set horizontally (see Fig. 5(A)).

[0040] In this way, when the angles of the finger insertion port 170A and the insertion space 170 are set, the user can insert the hand H into the insertion space 170 in a natural posture, and as a result, the situation where the hand H touches the first irradiation unit 110 and the second irradiation unit 220 can be suppressed.

[0041] The distance in the longitudinal direction LE of the strip of the finger insertion port 170A is set to be 220 mm or more and 620 mm or less. In this way, the user can insert the entire hands H into the insertion space 170 at the same time. The distance in the longitudinal direction LE is preferably 400 mm or less, and the entire device can be made compact.

[0042] With the above structure, by irradiating ultraviolet rays from both the first irradiation unit 110 and the second irradiation unit 220 to the fingers inserted into the insertion space 170, foreign substances adhering to the palms and the backs of both hands can be sterilized collectively. Although not particularly shown here, if a display unit for calling attention to the effect of "please widen the interval between fingers" is provided for the user, the gaps between fingers can also be sterilized. Since the user does not need to reverse the hand H in the insertion space 170, the contact with the first irradiation unit 110 and the second irradiation unit 220 can also be suppressed.

[0043] As shown in FIG. 1, a detection unit 180 for detecting that a finger has been inserted into the insertion space 170 is installed around the insertion space 170. This detection unit 180 can use a line sensor or a proximity sensor, and when a finger exists in the insertion space 170, it emits a presence signal. By using this signal, it is possible to determine the entry timing and the retraction timing of the finger.

[0044] Next, the control device 190 will be described.

[0045] As shown in FIG. 6(A), the control device 190 includes a computer, and is provided with a CPU 13, a RAM 14, a ROM 15, an input / output interface 16, a switch 17, a bus 18, and a control power supply 19. The CPU 13 is a so-called central processing unit, and various programs are executed to realize various functions. The RAM 14 is a so-called RAM (Random Access Memory), and is used as a work area for the CPU 13. The ROM 15 is a so-called ROM (Read Only Memory), and stores a basic OS and various programs (control programs in this embodiment) executed by the CPU 13. The switch 17 switches the ON / OFF of the first irradiation unit 110 and the second irradiation unit 220. The control power supply 19 is an AC-DC converter, which converts the AC voltage of the power supply 185 into a DC voltage. The input / output interface 16 is connected to the detection unit 180 and a gate device to be described later, and performs transmission and reception of various signals.

[0046] As shown in FIG. 6(B), as functions executed by the control program, the control device 190 has an irradiation start unit 20, an irradiation end unit 22, a standby processing unit 24, and an irradiation determination unit 26.

[0047] When the following determinations (1) and (2) are both satisfied, the irradiation start unit 20 turns on the first irradiation unit 110 and the second irradiation unit 220 using the switch 17. As a result, irradiation of ultraviolet rays by the ultraviolet lamp is started.

[0048] (1) Based on the signal of the detection unit 180, an insertion start determination meaning that a finger has been " newly inserted " into the insertion space 170.

[0049] (2) The standby processing unit 24 makes a second time elapse determination indicating that a predetermined second time has elapsed since the end of the previous irradiation.

[0050] Note that by combining the second time elapse determination in (2), continuous irradiation on the same person can be suppressed, but this determination in (2) is not essential.

[0051] The irradiation end unit 22 operates a timer starting from the above-described insertion start determination or the start of ultraviolet irradiation, makes a first time elapse determination indicating that a predetermined first time has elapsed, and turns off the first irradiation unit 110 and the second irradiation unit 220 using the switch 17 based on this first time elapse determination. As a result, the irradiation of ultraviolet rays by the ultraviolet lamp ends. Note that this first time is preferably within 10 seconds and is set to 5 seconds in the present embodiment. In this way, the ultraviolet irradiation on the hand H can be forcibly ended within the first time. Note that the irradiation end unit 22 preferably makes a retraction determination indicating that the finger has "retracted" from the insertion space 170. If the retraction determination is executed before the first time elapse determination, it is preferable to notify the user visually or audibly by a warning unit (not particularly shown) that the sterilization is incomplete because the sterilization time is insufficient. At the time of this notification, the first irradiation unit 110 and the second irradiation unit 220 may be turned off.

[0052] The standby processing unit 24 operates a timer starting from the end of irradiation by the irradiation end unit 22, and makes a second time elapse determination indicating that a predetermined second time has elapsed. The user can visually recognize that the sterilization has ended by using this second time, which is the ultraviolet lamp-off time, while keeping the hand H inserted. Also, this second time becomes a so-called standby time, and continuous use by the same user can be suppressed. This second time is preferably, for example, 3 seconds or more, more preferably 5 seconds or more. On the other hand, in order to enable the next user to quickly start hand sterilization after the sterilization of the previous user's hand is completed, the second time is preferably 10 seconds or less.

[0053] The irradiation determination unit 26 determines whether irradiation has been performed, which means that the finger inserted into the insertion space 170 has been irradiated with ultraviolet rays, and outputs the irradiation completion signal to the outside. That is, a signal indicating that the sterilization of the user's finger has been completed can be transmitted to the outside. Note that this irradiation execution determination can use any one of the following conditions, for example, or a combination of multiple conditions: (1) Irradiation has been started by the irradiation start unit 20. (2) Ultraviolet irradiation has been terminated by the irradiation end unit 22. (3) The notification (determination) of "insufficient irradiation time" in the irradiation end unit 22 has not occurred. (4) Based on the signal of the detection unit, it has been determined that the finger has always been present during the irradiation time.

[0054] Next, referring to FIG. 7, the gate system 300 according to the second embodiment of the present invention will be described. This gate system 300 includes the finger ultraviolet sterilizer 1 of the first embodiment and a gate device 400 connected thereto via a communication line. The gate device 400 has an opening / closing door 420, and by opening and closing this opening / closing door 420, passage through this gate is prohibited / allowed. The gate device 400 interlocks with receiving the irradiation completion signal from the irradiation determination unit 26 and opens the opening / closing door 420 to allow passage. As a result, it becomes possible to surely sterilize the fingers of the user without arranging a dedicated administrator for disinfection confirmation at the entrance of the facility.

[0055] Note that the type of this gate device 400 is not particularly limited, and it may be a so-called automatic door or an automatic locking system installed in a manual door.

[0056] Next, referring to FIG. 8, the finger ultraviolet sterilizer 500 according to the third embodiment of the present invention will be described. This finger ultraviolet sterilizer 500 is the same as the finger ultraviolet sterilizer 1 of the first embodiment except that the holding mode of the holding unit 550 is different (that is, the holding postures of the first and second irradiation units 110 and 120 are different). Therefore, the reference numerals of the components and members other than the holding unit 550 are made the same as those in the first embodiment, and individual descriptions are omitted.

[0057] The holding part 550 of the finger ultraviolet sterilizing device 500 holds the first irradiation part 110 and the second irradiation part 210 such that the ultraviolet irradiation planes (the planes of the first opening 124A and the second opening 224A) of the first irradiation part 110 and the second irradiation part 210 are in the vertical direction. As a result, the width direction WE of the finger insertion port 170A becomes horizontal, and the lengthwise direction LE of the strip has a predetermined angle γ with respect to the vertical direction and the horizontal direction. Specifically, the angle γ of this lengthwise direction LE of the strip is set to be 10° or more and 80° or less based on the horizontal direction, preferably 30° or more and 60° or less. In the present embodiment, it is set to 45° which is 40° or more and 50° or less.

[0058] In this way, the user can simultaneously insert both hands into the insertion space 170 through the finger insertion port 170A while shifting the heights of both hands while facing the palm or the back of the hand in the vertical direction. Also, since the first opening 124A and the second opening 224A are along the vertical direction, there is also an advantage that ultraviolet rays are less likely to enter the user's line of sight. Furthermore, since the overall width of the finger ultraviolet sterilizing device 500 becomes compact, the finger ultraviolet sterilizing device 500 can be installed in a narrow space.

[0059] Note that in the finger ultraviolet sterilizing device of the first to third embodiments, the case where the first irradiation part 110 and the second irradiation part 210 are provided as the irradiation parts is exemplified, but the present invention is not limited to this. For example, as in the finger ultraviolet sterilizing device 600 of FIG. 9, in the finger ultraviolet sterilizing device 1 of the first embodiment, the second irradiation part can be omitted. In this way, only the first irradiation part 110 can emit the first ultraviolet ray toward the floor side, so the user can sterilize while placing the palm in the insertion space 170 below the first irradiation part 110 and reversing the palm and the back of the hand. Also, there is an advantage that the first ultraviolet ray is less likely to enter the user's field of view.

[0060] Note that the finger ultraviolet sterilizing device and the gate system of the present invention are not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.
