[0009] (Findings that formed the basis of this disclosure) At the time the inventors came up with the idea for this disclosure, there was a technology in place that, when use of a guest room was finished, would fully open the motor damper of the guest room's ventilation system to exhaust air at maximum ventilation volume, thereby exhausting dust generated during cleaning and odors remaining in the guest room to the outside. However, in recent years, users have become increasingly concerned about the air environment in guest rooms, and there is a desire to stay in a room that has been thoroughly sterilized. Therefore, the inventors have discovered a problem in that simply exhausting dust and odors from the guest room when the guest room has finished using it does not meet the user's needs, and have come to constitute the subject of the present disclosure in order to solve this problem. Therefore, the present disclosure provides a guest room sterilization system that can provide a sufficiently sterilized guest room for users.

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] (Embodiment) Hereinafter, an embodiment will be described with reference to FIGS. [1. Configuration] The configuration of a guest room sterilization system 10 in the present disclosure and the facilities of an accommodation facility 1 equipped with the guest room sterilization system 10 will be described with reference to Figure 1. The guest room sterilization system 10 manages the implementation of sterilization treatments for guest rooms 50 equipped in the accommodation facility 1. The accommodation facility 1 has multiple guest rooms 50, but Figure 1 shows only one room for ease of explanation.

[0012] The guest room 50 is equipped with guest room facilities including a door lock 52, a card switch 53, a motion sensor 54, an illuminance sensor 55, a door sensor 56, a ventilation device 57, an air conditioner 58, and a second sterilization device 59. The guest room facilities 52 to 59 are connected to a communication network 200 via a router 51 by wireless communication such as Wi-Fi (registered trademark).

[0013] The door lock 52 is provided on the door (not shown) of the guest room 50, and when a card-type room key 100 held by a user U or the like of the guest room 50 is held over or inserted, the door is unlocked by performing authentication using the information recorded on the room key 100. The door lock 52 also locks the door when it is closed (auto-lock). If the door lock 52 has a smart lock function that supports unlocking via a communication terminal, the user U can unlock the door by operating a smart lock app installed on the user terminal 90.

[0014] The card switch 53 is placed near the door of the guest room 50 and turns the power to the guest room 50 on / off depending on whether the guest room key 100 is inserted or removed. The human presence sensor 54 senses infrared rays to detect people in the guest room 50. The illuminance sensor 55 detects the brightness of the guest room 50 based on the amount of light received by a light-receiving element. The door sensor 56 detects whether the door to the guest room 50 is opened or closed. The ventilation device 57 operates a ventilation fan (not shown) to ventilate the guest room 50.

[0015] The air conditioner 58 conditions the cabin 50. The air conditioner 58 includes the function of the air blower of the present disclosure. A first sterilization device 58a provided in the air conditioner 58 applies high voltage to water in the air to generate nano-sized particulate ions, which are then released into the cabin 50, thereby sterilizing the cabin 50 by the oxidizing power of OH radicals contained in the particulate ions. The second sterilization device 59 is, for example, an air purifier, and sterilizes the air in the cabin 50 by drawing in air from the cabin 50 and circulating it through a filter impregnated with a hypochlorous acid solution. When the second sterilization device 59 is operated to sterilize the cabin 50, the ventilation device 57 is stopped to fill the cabin 50 with hypochlorous acid, a sterilizing component, and operation of the ventilation device 57 is resumed after sterilization is completed.

[0016] The sterilization capability of the second sterilization device 59 (sterilization using hypochlorous acid) is higher than that of the first sterilization device 58a (sterilization using OH radicals), and in terms of sterilization efficiency, using the second sterilization device 59 is more effective than using the first sterilization device 58a. However, the second sterilization device 59 requires maintenance such as replenishing salt tablets, whereas the first sterilization device 58a can be operated maintenance-free. Therefore, it is desirable for the accommodation facility 1 to sterilize guest rooms using the first sterilization device 58a as much as possible. Therefore, in the accommodation facility 1, guest rooms are basically sterilized using the first sterilization device 58a, and when time is tight, guest rooms are sterilized using the second sterilization device 59.

[0017] Furthermore, the accommodation facility 1 is equipped with a management device 70 having a guest room management DB (database) 71 in which information such as scheduled occupancy information for guest room 50 is recorded, and a guest room key collection device 80. The management device 70 is placed, for example, at the front desk of the accommodation facility 1, and information such as check-in and check-out completion information for guest room 50 is input by an employee of the accommodation facility 1. The management device 70 records the check-in and check-out completion information for guest room 50 in the guest room management DB 71.

[0018] 2, the guest room management DB 71 stores guest room management information for each guest room, including the check-out status, cleaning status, amenity replenishment status, room disinfection status, and information on the next scheduled check-in date and time. The information on the scheduled check-in date and time corresponds to the planned use information of the present disclosure.

[0019] The room key collection device 80 is installed, for example, in the lobby of the accommodation facility 1 and collects the room keys 100. The room key collection device 80 transmits the room number information recorded on the collected room keys 100 to the management device 70. Upon receiving the room number information, the management device 70 executes check-out processing for the corresponding room and records check-out completion information in the room management DB 71. This allows the user U to complete check-out simply by returning the room key 100 to the room key collection device 80.

[0020] The guest room sterilization system 10, the management device 70, and the guest room key collection device 80 are connected to a communication network 200 and communicate with each other via the communication network 200. The communication network 200 may be a LAN (Local Area Network) of the accommodation facility 1 or a WAN (Wide Area Network) such as a public line. The guest room sterilization system 10 communicates with guest room equipment 52-59 via the communication network 200 and a router 51 in the guest room 50.

[0021] Furthermore, employee terminals 91 and 92 used by employees E1 and E2, who perform various maintenance tasks such as cleaning guest room 50 and replenishing amenities, communicate with the management device 70 via communication network 200. For example, if employee E1 is in charge of cleaning guest room 50 and employee E2 is in charge of replenishing amenities in guest room 50, employee E1 operates employee terminal 91 to send cleaning completion information to the management device 70 when cleaning guest room 50 is completed. Furthermore, employee E2 operates employee terminal 92 to send amenity replenishment completion information to the management device 70 when replenishing amenities in guest room 50 is completed. When receiving the cleaning completion information, the management device 70 records the cleaning completion information for guest room 50 in the guest room management DB 71, and when receiving the amenity replenishment completion information, the management device 70 records the amenity replenishment completion information for guest room 50 in the guest room management DB 71.

[0022] The guest room sterilization system 10 is a computer system composed of a communicator 11, a processor 20, a memory 30, etc. The memory 30 stores a control program 31 that is read from a recording medium 40 (such as a magnetic disk, magnetic tape, optical disk, or flash memory) or downloaded from an external system such as a management device 70.

[0023] By reading and executing the control program 31, the processor 20 functions as a check-out recognition unit 21, a maintenance completion recognition unit 22, a guest room sterilization control unit 23, a check-in recognition unit 24, and an entry / exit recognition unit 25. The entry / exit recognition unit 25 includes the functions of the entry recognition unit of the present disclosure.

[0024] The check-out recognition unit 21 recognizes that the guest room 50 has been checked out by the following check-out recognition methods 1 to 3. Check-out recognition method 1: The check-out recognition unit 21 recognizes that the guest room 50 has been checked out when it determines through communication between the guest room sterilization system 10 and the management device 70 that check-out completion information for the guest room 50 has been entered into the management device 70. Check-out recognition method 2: The check-out recognition unit 21 recognizes that the guest room 50 has been checked out when it determines through communication between the guest room sterilization system 10 and the guest room key collection device 80 that the guest room key 100 for the guest room 50 has been collected by the guest room key collection device 80. Check-out recognition method 3: The check-out recognition unit 21 recognizes that the guest room 50 has been checked out when it determines that the scheduled check-out date and time for the guest room 50, recognized by referring to the guest room management DB 71, has passed. Note that when the check-out date for the guest room 50 is the same day, the check-out recognition unit 21 may recognize that the guest room 50 has been checked out when the preset upper limit time for check-out for the guest room (such as 10:00) has passed. The check-out recognition unit 21 may recognize that the guest room 50 has been checked out by using one or two of the above check-out recognition methods 1 to 3, rather than by using all of them.

[0025] The maintenance completion recognition unit 22 recognizes that maintenance of the guest room 50 is complete when it recognizes through communication between the guest room sterilization system 10 and the management device 70 or the employee terminals 91, 92 that cleaning completion information for the guest room 50 and information that amenities have been replenished in the guest room 50 have been entered into the management device 70. The maintenance completion recognition unit 22 may also be configured to recognize that cleaning completion information for the guest room 50 and information that amenities have been replenished in the guest room 50 have been entered into the management device 70 by referring to the guest room management DB 71.

[0026] The guest room sterilization control unit 23 transmits control information to the ventilation device 57, the air conditioner 58, and the second sterilization device 59 via the communication network 200, thereby controlling the operation of the ventilation device 57, the air conditioner 58 (including the first sterilization device 58a), and the second sterilization device 59, and performs guest room sterilization processing to sterilize the guest room 50. The execution procedure for the guest room sterilization processing will be described in detail later.

[0027] The check-in recognition unit 24 recognizes that the guest room 50 has been checked in when it recognizes through communication between the guest room sterilization system 10 and the management device 70 that check-in completion information for the guest room 50 has been entered into the management device 70. Note that the check-in recognition unit 24 may also recognize that the guest room 50 has been checked in by referring to the guest room management DB 71.

[0028] The entry / exit recognition unit 25 recognizes entry into and exit from the guest room 50 by any one of the following entry / exit recognition methods 1 to 5. The configuration in which the entry / exit recognition unit 25 recognizes entry into the guest room 50 corresponds to the entry recognition unit of the present disclosure. Entry / Exit Recognition Method 1: The entry / exit recognition unit 25 recognizes entry into the guest room 50 when it determines that the door lock is unlocked through communication between the guest room sterilization system 10 and the door lock 52. The entry / exit recognition unit 25 also recognizes exit from the guest room 50 when it determines that the door lock is locked through communication between the guest room sterilization system 10 and the door lock 52.

[0029] Entry / Exit Recognition Method 2: The entry / exit recognition unit 25 recognizes entry into the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the card switch 53, that the guest room key 100 has been inserted into the card switch 53. In addition, the entry / exit recognition unit 25 recognizes exit from the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the card switch 53, that the guest room key 100 has been removed from the card switch 53.

[0030] Entry / Exit Recognition Method 3: The entry / exit recognition unit 25 recognizes entry into the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the human presence sensor 54, that the human presence sensor 54 has detected a person. In addition, the entry / exit recognition unit 25 recognizes exit from the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the human presence sensor 54, that the human presence sensor 54 has stopped detecting a person.

[0031] Entry / Exit Recognition Method 4: The entry / exit recognition unit 25 recognizes entry into the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the illuminance sensor 55, that the illuminance detected by the illuminance sensor 55 has increased (assuming the lights in the guest room 50 have been turned on). Also, the entry / exit recognition unit 25 recognizes exit from the guest room 50 when it determines, through communication between the guest room sterilization system 10 and the illuminance sensor 55, that the illuminance detected by the illuminance sensor 55 has decreased (assuming the lights in the guest room 50 have been turned off).

[0032] Entry / Exit Recognition Method 5: The entry / exit recognition unit 25 recognizes entry into the guest room 50 when it determines that the door has been opened through communication between the guest room sterilization system 10 and the door sensor 56. The entry / exit recognition unit 25 then recognizes exit from the guest room 50 when it determines that the door has been closed through communication between the guest room sterilization system 10 and the door sensor 56. The entry / exit recognition unit 25 may recognize entry into and exit from the guest room 50 by using at least one of the entry / exit recognition methods 1 to 5, rather than by using all of them.

[0033] [2. Guest room sterilization] 3 and 4, the procedure for executing the guest room sterilization process performed by the guest room sterilization system 10 will be described. The guest room sterilization system 10 performs the guest room sterilization process for each of the multiple guest rooms 50 provided in the accommodation facility 1 according to the procedure described below.

[0034] 3, when the check-out recognition unit 21 recognizes that the guest room 50 has been checked out, the process proceeds to step S2. In step S2, the guest room sterilization control unit 23 proceeds to step S3 when a predetermined time has elapsed since check-out of the guest room 50 was completed. The elapse of a predetermined time since check-out of the guest room 50 was completed corresponds to the predetermined condition based on the recognition that the guest room has been checked out in the present disclosure.

[0035] The predetermined time in step S2 is set to, for example, two hours, assuming the time from when the guest room 50 is checked out until the maintenance work of the guest room 50, which includes cleaning and replenishing amenities, is completed and the maintenance of the guest room 50 is completed. This allows the guest room 50 to be sterilized after the maintenance of the guest room 50 is completed.

[0036] In step S3, the guest room sterilization control unit 23 references the guest room management information stored in the guest room management DB 71 and recognizes the next scheduled check-in date and time for the guest room 50. In the next step S4, if the next scheduled check-in date and time for the guest room 50 is the following day or later, the guest room sterilization control unit 23 proceeds to step S20 and schedules the execution of guest room sterilization processing on the scheduled check-in date. On the other hand, if the next scheduled check-in date for the guest room 50 is the same day, the guest room sterilization control unit 23 proceeds to step S5. In step S5, the guest room sterilization control unit 23 calculates the available time from the current time to the scheduled check-in time.

[0037] Here, in the processing of steps S1 to S4, if all of the following conditions are met: (1) check-out of guest room 50 is recognized, (2) a predetermined time has passed since the time of check-out recognition, and (3) the next scheduled check-in date is the same day, this corresponds to the predetermined condition based on check-out being recognized in this disclosure.

[0038] In the following step S6, the guest room sterilization control unit 23 determines whether the vacant time is equal to or greater than a determination time. Here, the determination time is set to, for example, 8 hours based on the time required for the first sterilization device 58a to sterilize the guest room 50. If the vacant time is equal to or greater than the determination time, the guest room sterilization control unit 23 proceeds to step S30, where it operates the first sterilization device 58a and performs guest room sterilization processing by blowing air using the air conditioner 58. The air volume of the air blown by the air conditioner 58 is set to, for example, one of three levels: strong, medium, or weak.

[0039] On the other hand, when the available time is shorter than the determination time, the guest room sterilization control unit 23 proceeds to step S7 and activates the second sterilization device 59 to perform guest room sterilization processing. By thus determining either the first sterilization device 58a or the second sterilization device 59 depending on the available time from check-out to the next check-in, when there is ample available time, the guest room sterilization processing can be performed using the first sterilization device 58a, which can be operated without maintenance. When there is not enough available time, the guest room sterilization processing can be performed quickly using the second sterilization device 59, which can complete sterilization in a shorter time than the first sterilization device 58a.

[0040] In the next step S8 in FIG. 4, the guest room sterilization control unit 23 determines whether the guest room sterilization process is complete. The guest room sterilization control unit 23 determines whether the guest room sterilization process is complete based on the execution time of the guest room sterilization process. When the guest room sterilization process is performed by operating the first sterilization device 58a, the guest room sterilization control unit 23 determines that the guest room sterilization process is complete when the operation time of the first sterilization device 58a exceeds 8 hours, for example. When the guest room sterilization process is performed by operating the second sterilization device 59, the guest room sterilization control unit 23 determines that the guest room sterilization process is complete when the operation time of the second sterilization device 59 exceeds 15 minutes, for example.

[0041] If the guest room sterilization process is completed, the guest room sterilization control unit 23 proceeds to step S9, and if the guest room sterilization process is not completed, the process proceeds to step S40. In step S40, if the entry / exit recognition unit 25 recognizes entry into the guest room 50, the process proceeds to step S41, and if the entry into the guest room 50 is not recognized, the process proceeds to step S9.

[0042] In step S41, the guest room sterilization control unit 23 interrupts the guest room sterilization process that is currently being performed. In the following step S42, when the entry / exit recognition unit 25 recognizes that a guest has left the guest room 50, the process proceeds to step S43. In step S43, the guest room sterilization control unit 23 resumes the guest room sterilization process, and the process proceeds to step S8. Here, depending on the interruption time from when the guest room sterilization control unit 23 interrupted the guest room sterilization process in step S41 to when the guest room sterilization process is resumed in step S43, the execution time of the guest room sterilization process after resumption may be extended by, for example, the interruption time.

[0043] In step S9, the guest room sterilization control unit 23 starts standby processing for the guest room 50. As standby processing for the guest room 50, the guest room sterilization control unit 23 performs processing in which only air is blown by the air conditioner 58 (second standby processing of the present disclosure). The air volume of the air blown at this time is set to low. Furthermore, not only air blowing but also sterilization may be performed (first standby processing of the present disclosure). The sterilization capacity at this time may be lower than when the guest room sterilization processing was performed. The guest room standby processing promotes ventilation and deodorization of the guest room 50. When the second sterilization device 59 is operated during the guest room sterilization processing, some occupants of the guest room 50 may smell a chlorine odor, but this chlorine odor can be reduced by blowing air during the standby processing.

[0044] In the next step S10, the check-in recognition unit 24 proceeds to step S11 when it recognizes that check-in for the guest room 50 has been completed, and proceeds to step S50 when it does not recognize check-in for the guest room 50. In step S11, the guest room sterilization control unit 23 ends the guest room standby process.

[0045] Furthermore, in step S50, if the entry / exit recognition unit 25 recognizes entry into the guest room 50 before check-in, the process proceeds to step S51, and if it does not recognize entry into the guest room 50, the process proceeds to step S9. In step S51, the guest room sterilization control unit 23 ends the guest room standby process. In the following step S52, if the entry / exit recognition unit 25 recognizes exit from the guest room 50, the process proceeds to step S53. In step S53, the guest room sterilization control unit 23 executes additional guest room sterilization processing, and then proceeds to step S9.

[0046] The guest room sterilization control unit 23 basically operates the first sterilization device 58a to perform the additional guest room sterilization process, but may operate the second sterilization device 59 when the time until the scheduled check-in time is short (for example, within one hour). Furthermore, the sterilization capacity setting of the first sterilization device 58a when performing the additional guest room sterilization process may be the same as in step S30, or may be lowered (set to weaker) than in step S30 to reduce the amount of particulate ions released. Furthermore, the time period for performing the additional guest room sterilization process may be the same as in step S30, or may be shorter than in step S30.

[0047] In the example shown in FIG. 2, the processing according to the flowcharts in FIGS. 3 and 4 allows for room No. 101 to be sterilized by the scheduled check-in time on the day, since a predetermined time (assumed to be one hour here) has passed since check-out was completed. For room No. 102, a predetermined time has passed since check-out was completed, but the scheduled check-in date is the following day, so room sterilization is scheduled for the following day. For room No. 103, a predetermined time has not passed since check-out was completed, so room sterilization has not yet been performed. For room No. 104, check-out has not yet been completed, so room sterilization has not yet been performed.

[0048] [3. Effects, etc.] As described above, in this embodiment, the processor 20 constituting the guest room sterilization system 10 functions as the check-out recognition unit 21 and the guest room sterilization control unit 23. Then, when a predetermined time has elapsed since the check-out recognition unit 21 recognized that the guest room 50 has been checked out, the guest room sterilization control unit 23 executes a guest room sterilization process to sterilize the guest room 50 by operating the first sterilization device 58a or the second sterilization device 59. This allows guest room 50 to be disinfected at the time when it is assumed that guest room 50 has been checked out and maintenance such as cleaning of guest room 50 has been completed, making it possible to provide a thoroughly disinfected guest room for the next occupant of the room.

[0049] (Other embodiments) As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Therefore, other embodiments will be described below as examples.

[0050] In the above embodiment, the guest room sterilization control unit 23 executes the guest room sterilization process on the scheduled check-in date when the next scheduled check-in date for the guest room 50 is the day after check-out or later, by the processing of steps S4 and S20 in Fig. 3. In another embodiment, the processing of steps S4 and S20 may be omitted, and the guest room sterilization process may be executed on the day of check-out, even if the next scheduled check-in date for the guest room 50 is the day after check-out or later.

[0051] In the above embodiment, the guest room sterilization control unit 23 determines whether to operate the first sterilization device 58a or the second sterilization device 59 to perform the guest room sterilization process, depending on the available time until the scheduled check-in time, through the process of steps S5 to S7 and S30 in Fig. 3. In another embodiment, the process of steps S5 to S7 and S30 may be omitted, and the second sterilization device 59, which has a higher sterilization capability, may be uniformly operated to perform the guest room sterilization process.

[0052] In the above embodiment, the guest room sterilization control unit 23, by processing steps S8, S40 to S43 in Figure 4, interrupts the guest room sterilization process when it recognizes entry into the guest room 50 while the guest room sterilization process is being performed, and resumes the guest room sterilization process when it recognizes exit from the guest room 50. In another embodiment, the processing of steps S40 to S43 may be omitted, and a configuration may be adopted in which entry into the guest room 50 is not determined while the guest room sterilization process is being performed.

[0053] In the above embodiment, the guest room sterilization control unit 23 executed standby processing for the guest room 50 in step S9 of FIG. 4, but the processing of steps S9, S51, and S11 may be omitted, and the standby processing may not be performed.

[0054] In the above embodiment, the guest room sterilization control unit 23 performed additional guest room sterilization processing when entry into the guest room 50 was recognized before check-in, according to steps S10, S50 to S53 in Fig. 4. In another embodiment, the processing of steps S50 to S53 may be omitted, and additional guest room sterilization processing may not be performed.

[0055] In the above embodiment, a configuration in which the guest room sterilization system 10 is provided in the accommodation facility 1 has been exemplified, but the guest room sterilization system 10 may be located in a location separate from the accommodation facility 1. In this case, the guest room sterilization system 10 communicates with the guest room equipment 52-59 of the guest room 50, the management device 70, and the guest room key collection device 80 via a WAN. The guest room sterilization system 10 may also be configured as part of the functions of the management device 70.

[0056] In the above embodiment, the predetermined condition for executing the guest room sterilization process is set to be that all of the following conditions are met: (1) check-out of the guest room 50 is recognized, (2) a predetermined time has passed since the check-out was recognized, and (3) the next scheduled check-in date is the same day. In another embodiment, the predetermined condition for executing the guest room sterilization process may be set to any of the following predetermined conditions 1 to 3. Predetermined condition 1: A predetermined time has elapsed since check-out of guest room 50 was recognized. Predetermined condition 2: After check-out of the guest room 50 is recognized, the maintenance completion recognition unit 22 recognizes that maintenance of the guest room 50 has been completed. Predetermined condition 3: After check-out of guest room 50 is recognized, the maintenance completion recognition unit 22 recognizes that maintenance of guest room 50 has been completed, and further, the next scheduled check-in date for guest room 50 is the same day that check-out was recognized.

[0057] In the above embodiment, the guest room sterilization control unit 23 recognizes the next scheduled check-in date and time for the guest room 50 and calculates the vacant time of the guest room 50 through the processing of steps S3 and S5 in FIG. 3 , and determines whether to operate the first sterilization device 58a or the second sterilization device 59 in the guest room sterilization process based on the vacant time.

Examples of processors include a central processing unit (CPU) and a microprocessing unit (MPU). Examples of storage media include a hard disk, flash memory, and optical disk. Furthermore, wired logic, which does not allow rewriting of programs, may be used as the controller. Using wired logic as the controller is effective in improving processing speed. Examples of wired logic include an application-specific integrated circuit (ASIC). The cabin sterilization system may also be implemented by combining a processor and wired logic. By implementing a controller by combining a processor and wired logic, it is possible to increase the flexibility of software design while improving processing speed. A circuit having the cabin sterilization system function and a circuit having a different function may be configured with a single semiconductor element. An example of a circuit having a different function is an A / D / D / A conversion circuit. The controller may also be configured with a single semiconductor element or multiple semiconductor elements. When configured with multiple semiconductor elements, each control described in the claims may be realized by a different semiconductor element. Furthermore, a circuit having the cabin sterilization system function may be configured with a semiconductor element and a passive component such as a resistor or capacitor.

[0060] The communicator in the present disclosure may be any device that enables communication between the guest room sterilization system of the present disclosure and an external device. When describing the subject matter of the invention, the device that enables communication between the guest room sterilization system of the present disclosure and an external device may be referred to as a communication means, a communication unit, a transmission / reception means, a transmission / reception unit, or similar terms in addition to a communicator. The communicator can be realized in various forms. Examples of the communicator include a wireless connection with an external device via a base station or a direct wireless connection with an external device. Examples of wireless connections with an external device via a base station or the like include an IEEE 802.11-compatible wireless LAN that wirelessly communicates with a Wi-Fi (registered trademark) router, a third-generation mobile communication system (commonly known as 3G), a fourth-generation mobile communication system (commonly known as 4G), an IEEE 802.16-compatible WiMax (registered trademark), or a low-power wide area (LPWA) network. The use of a communicator that directly and wirelessly connects the guest room sterilization system 10 of the present disclosure to an external device is effective in improving communication security and allows the device of the present disclosure to communicate with external devices even in places where there is no relay device such as a Wi-Fi (registered trademark) router. Examples of communicators that directly and wirelessly connect the guest room sterilization system of the present disclosure to an external device include communication via Bluetooth (registered trademark), communication via NFC (Near Field Communication) via a loop antenna, and infrared communication.
