Description

  The present invention relates to an automatic door interlocking type dry sterilization apparatus.

  Traditionally, clean hands when entering and leaving rooms in various factories such as hospital waste treatment rooms, intensive care units, hospital rooms, toilets for hospitals, welfare facilities for the elderly and public facilities, restaurant kitchens, food processing factories, etc. In particular, in order to avoid human damage such as food poisoning and nosocomial infections caused by Staphylococcus aureus, Salmonella, pathogenic Escherichia coli O-157, norovirus, etc. in recent years, it is required to sterilize the various pathogens. It has been.

  For this reason, conventionally, hand washers, disinfectants, etc. have been installed in places where hand washing is required, so as to sterilize and wash hands. However, since a conventional disinfectant is a disinfection by supplying alcohol for disinfection to the hand, for example, pathogens such as norovirus have a small disinfection effect and cannot always be completely disinfected.

On the other hand, when leaving the room after cleaning the hands with a hand-washer or disinfector, the doorway of the room should be an automatic door in order to prevent the washed hands from being contaminated again or to improve the convenience for the handicapped. In addition, in order to prevent the person from leaving the room without washing hands and to ensure hygiene management, the handwasher and disinfectant are linked to the automatic door, and the handwasher and disinfectant are linked. In order to prevent the automatic door from opening only after the use of the door (see, for example, Patent Document 1). However, in the case of this type of device, it can be confirmed that either a handwashing device or a disinfecting device has been used, but it is not always possible to confirm whether the hand has been sterilized by the handwashing device or the disinfecting device. There was a risk of leaving the room in a sterilized condition.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an automatic door-linked dry sterilization apparatus that is a compact facility and that can only be left after sterilizing various pathogens. There is to do.

The invention according to claim 1 of the present application detects hand washing means for washing a hand, a hand insertion part for inserting a hand, and that a hand is inserted into a predetermined position of the hand insertion part in a non-contact state with the hand. Inserting into the hand insertion part by comprising a detection part, a drying mechanism for drying the hand inserted into the hand insertion part, and ultraviolet sterilization means for sterilizing the hand inserted into the hand insertion part by irradiating with ultraviolet rays Drying sterilization means that sterilizes the hand by ultraviolet rays at the same time , automatic door, and when the hand is inserted into the hand insertion portion of the dry sterilization means to detect this and start the operation of the dry sterilization means, When the hand is pulled out from the manual insertion portion of the dry sterilization means after the time for completing the sterilization has elapsed since the start of sterilization in the dry sterilization means and before reaching the predetermined longest sterilization time. to allow the opening of the automatic door, and the self And control means you limit the time that has allowed the opening of the door,
It is in the automatic door interlocking type dry sterilization apparatus characterized by having.

The invention according to claim 2 of the present application is such that the dry sterilization means displays that a predetermined time has elapsed every time a predetermined time has elapsed since the start of irradiation of ultraviolet rays by the ultraviolet sterilization means. as well as comprising a, the control unit is in the automatic door-linked dry disinfection device according to claim 1, characterized in that to stop the operation of the drying sterilizing means and the irradiation time of the ultraviolet light reaches the maximum sterilizing time .

  According to the first aspect of the present invention, since the sterilization means using ultraviolet rays is used as the sterilization means, the sterilization means can be more surely sterilized than other means such as alcohol for disinfection, and at the same time, sterilization using ultraviolet rays is performed. Can be easily integrated, and a compact dry sterilization means can be constructed, thereby reducing the installation space of the automatic door-linked dry sterilization apparatus as a whole.

  In addition, since the automatic door is allowed to open when a predetermined time has elapsed since the start of sterilization in the dry sterilization means, the automatic door is opened unless the sterilization is continued for a predetermined time or more when the sterilization is surely completed. Therefore, only those who have been sterilized reliably can leave and the hygiene management of the room is ensured.

Moreover, since the time during which the automatic door is allowed to open is limited, it is possible to reliably prevent a person who has completely sterilized his / her hand from touching each part of the room again and then leaving the room after being recontaminated.

In addition, the hand inserted into the hand insertion portion can be reliably dried and sterilized in a non-contact state.

According to the second aspect of the present invention, it is possible to inform the person who is sterilizing the hand of the time until the sterilization is completely completed after the ultraviolet irradiation is started by the sterilization time display unit. Further, by setting the longest sterilization time, it is possible to prevent sterilization more than necessary.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall schematic configuration diagram of an automatic door interlocking type dry sterilization apparatus 1 according to an embodiment of the present invention. As shown in the figure, this automatic door-linked dry sterilization apparatus 1 includes a hand-washing means (hereinafter referred to as “automatic hand-washer” in this embodiment) 10 for washing hands without contact, and a hand inserted into a hand insertion portion 37. A non-contact drying and sterilization means (hereinafter referred to as “dry sterilization apparatus” in this embodiment) 30, a control means 50 for driving and controlling the dry sterilization apparatus 30, and an automatic door 70. Has been. The automatic door 70 is provided with automatic door control means 80 for driving and controlling the automatic door 70. Each component will be described below.

  The automatic hand-washing means 10 detects that a hand has approached on the wash basin 11 by a sensor (not shown) and automatically supplies water for cleaning water, and detects that a hand has approached by a sensor (not shown). Thus, a cleaning liquid supply pipe 15 for automatically supplying a cleaning liquid such as a disinfecting liquid or a soap liquid is installed. That is, the automatic hand-washing means 10 is a hand-washing means that detects that the hand is located at a predetermined position (upper part of the washbasin 11) in a non-contact state with the hand and supplies washing water or washing liquid to the hand.

  FIG. 2 is a schematic side view of the dry sterilizer 30. As shown in FIGS. 1 and 2, the dry sterilizer 30 includes a device main body 31 formed in a box shape and a lower end 33 on the back side of the device main body 31. A manual insertion portion forming member 35 that is bent substantially at right angles to the side and bent in a L-shape as a whole, and in front of the apparatus main body 31 and the L-shaped manual insertion portion formation member 35. A space formed on the side is a hand insertion portion 37. A blower port 39 of a drying mechanism 38 (see FIG. 3) that blows warm air (heated air) toward the manual insertion portion 37 is provided on the lower surface of the apparatus main body 31, and also near the lower surface of the apparatus main body 31 (manual insertion). Ultraviolet sterilizing means (hereinafter referred to as “sterilizing lamp” in this embodiment) 41 is installed in the upper part of the portion 37. In addition, a detection unit 43 (see FIG. 3) that detects that the hand has been inserted at a predetermined position in the hand insertion unit 37 in a non-contact state with the hand is installed around the hand insertion unit 37. On the other hand, a sterilization time display unit 45 is attached to the front side surface of the apparatus main body 31. The sterilization time display unit 45 is configured by arranging a plurality of (three in this embodiment) lighting lamps (LED lamps) 45-1 to 45-3 in a line.

  FIG. 3 is a schematic control block diagram of the control means 50 and the automatic door control means 80. As shown in the figure, the control means 50 inputs a detection signal from a detection unit 43 that detects that a hand has been inserted into the hand insertion unit 37, and the sterilization lamp 41 and a fan constituting the drying mechanism 38. 381 and heater 383 (both built in the apparatus main body 31) and the sterilization time display unit 45 are each configured to output drive signals. Further, the control means 50 outputs an automatic door opening permission signal for allowing the automatic door control means 80 to open the automatic door 70.

  On the other hand, the automatic door control means 80 inputs a signal from a door opening indicator 81 composed of a sensor, a switch or the like for detecting when a person is positioned in front of the automatic door 70 and automatically drives the automatic door 70. The drive / stop signal is output to the door drive device 83.

  First, the outline of the operation of the automatic door-linked dry sterilization apparatus 1 will be described. When a hand is inserted into the hand insertion portion 37 of the dry sterilization apparatus 30 shown in FIG. Dry sterilization is started. The dry sterilization time is displayed on the lighting lamps 45-1 to 45-3, and the lighting lamps 45-1 to 45-3 are turned on one by one every 7 seconds. When 21 seconds (the longest sterilization time) has elapsed since the start of the dry sterilization by the dry sterilization apparatus 30, the operation of the dry sterilization apparatus 30 is automatically stopped, and then for a predetermined time (in this embodiment, 2 seconds). Only the automatic door 70 can be opened. If the irradiation time of the ultraviolet rays by the dry sterilizer 30 exceeds 14 seconds, the automatic door 70 opens for a predetermined time even if the hand is subsequently pulled out from the hand insertion portion 37 and the dry sterilizer 30 is stopped. In other words, when the irradiation time of ultraviolet rays is less than 14 seconds, the automatic door 70 is not opened when the hand is pulled out from the hand insertion portion 37 and the dry sterilization apparatus 30 is stopped. This is due to the following reason. That is, sterilization by ultraviolet rays is more effective than alcohol sterilization. For example, Escherichia coli (O157: H7), Salmonella, Staphylococcus aureus, Norovirus, etc. are almost killed by irradiation with ultraviolet rays (especially shortwave ultraviolet rays) for 5 seconds. Experiments have confirmed that 100% of the material is killed by UV irradiation for a second. Therefore, in the present invention, if the hand is not completely sterilized by irradiating the hand with ultraviolet rays for 14 seconds or more exceeding 10 seconds, a signal for instructing opening is issued from the door opening indicator 81 of the automatic door 70, for example. Even if it is input to the automatic door control means 80, the automatic door 70 is configured not to open. The operation will be specifically described below.

  FIG. 4 is an operation flowchart of the automatic door interlocking type dry sterilization apparatus 1. As shown in the figure, when a hand is first inserted into the hand insertion part 37 of the dry sterilization apparatus 30 (step 1), this is detected by the detection part 43, and the control means 50 drives the fan 381 and the heater 383. Then, heated air is blown out from the air blowing port 39 and blown onto the hand for drying, and at the same time, the sterilization lamp 41 is turned on to start sterilization by ultraviolet rays of the hand (step 2). Simultaneously with the lighting of the germicidal lamp 41, the first lighting lamp 45-1 in the germicidal time display section 45 is lighted (step 3).

  Next, when the state in which the hand is inserted continues for 7 seconds, the second lighting lamp 45-2 is turned on (steps 4 and 5). At this time, the first lighting lamp 45-1 may be kept on or may be turned off. On the other hand, if the hand is pulled out from the hand insertion part 37 during this time, the driving of the drying sterilizer 30 is stopped (ie, the driving of the drying mechanism 38 is stopped and the sterilizing lamp 41 is turned off), and the lighting lamp 45-1 is turned off at the same time ( Steps 6, 10) and return to Step 1.

  If the state in which the hand is inserted in step 5 continues for 7 seconds after the lighting lamp 45-2 is turned on, the third lighting lamp 45-3 is turned on (steps 7 and 8). At this time, the first and second lighting lamps 45-1 and 45-2 may remain on or be turned off. On the other hand, if the hand is pulled out from the hand insertion part 37 during this time, the driving of the drying sterilizer 30 is stopped (ie, the driving of the drying mechanism 38 is stopped and the sterilizing lamp 41 is turned off), and the lighting lamps 45-1 and 45-2 are turned off at the same time. (Steps 9 and 10), the process returns to Step 1.

  When the lighting of the lighting lamp 45-3 continues from step 8 for another 7 seconds in step 8 or when the hand is pulled out from the hand insertion part 37 before that, the operation of the dry sterilizer 30 is stopped (steps 11 and 12). . When one second has elapsed since the operation of the dry sterilization apparatus 30 was stopped (step 13), an automatic door opening permission signal is transmitted from the control means 50 to the automatic door control means 80, whereby the automatic door 70 can be freely opened and closed for two seconds. (Steps 14 and 15). Accordingly, if a signal for opening the automatic door control means 80 is input by the door opening indicator 81 during this period, the automatic door 70 is opened. When the two seconds have elapsed, the automatic door opening permission signal transmitted from the control means 50 to the automatic door control means 80 is turned off (step 16), and the automatic door 70 is again automatically controlled by the door opening indicator 81, for example. Even if a signal for opening it is input to the means 80, it cannot be opened. In other words, the control means 50 limits the time during which the automatic door 70 is allowed to open, so that there is a possibility that the hand is not completely sterilized (a person who has not been sterilized by the dry sterilizer 30 or once. The person who stayed in the room after completing the sterilization and whose hands may have been contaminated again is reliably prevented from leaving the room.

  In this embodiment, the plurality of lighting lamps 45-1 to 45-3 are sequentially turned on with the passage of time to indicate that the predetermined time has passed each time a predetermined time has elapsed since the start of ultraviolet irradiation. The reason for this is to inform the person who is inserting the hand of an approximate time until a predetermined time (14 seconds) elapses.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape or structure not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are achieved. For example, in the above-described embodiment, the automatic hand-washing means 10 that can wash hands without contact is used as the hand-washing means 10, but hand-washing means that discharges washing water or the like by touching the hand may be used. Needless to say, the dry sterilization means 30 can be variously modified.
