Thereby, it can confirm that the toilet is in use outside.

JP-A-2005-163408 JP 2005-179983 A

  However, since the lamp in use is turned on by operating the internal close switch, for example, when the internal close switch is operated by mischief, the lamp in use remains on even though there is no person in the room. End up. That is, when the internal closing switch is pressed without entering the room, the lamp in use may remain lit even though there is no person in the room. In this case, it is possible to set the lamp to turn off after a certain period of time (this constant time is longer than the general toilet use time, for example, about 30 minutes so as not to hinder normal use) However, even in that case, the toilet cannot be used while the lamp is on. In other words, the toilet cannot be used even though there are no people in the room for a considerable length of time.

  Therefore, the present invention has been made in view of the above prior art, and an object of the present invention is to make it possible to confirm from the outside whether or not there is actually a person in the room.

  In order to achieve the above object, the present invention provides a motor for driving a door that partitions the interior and the exterior, an internal closing switch disposed indoors, an external opening switch disposed outdoor, the internal closing switch, and the external A drive control means for controlling the driving of the motor in response to an operation of an opening switch; an external notification section that is arranged outside the room and notifies information; an internal notification section that is arranged inside the room and notifies information; In order to detect that there is a person in the room, and a lock control means for performing a control so that the door cannot be opened even by operating the external opening switch by operating the internal closing switch The occupancy detection sensor and the lock control means are controlled so that the door cannot be opened even by operating the external opening switch. Sometimes when the external opening switch is operated, when the internal closing switch is operated or a person is detected by the occupancy detection sensor, a notification indicating that the external opening switch is in use is sent to the external notification. An automatic door having a notification control means performed by the unit.

  In the present invention, when the internal closing switch is operated or a person is detected by the occupancy detection sensor, the external notification unit notifies that the user is in use. That is, it is notified that the device is in use based on the action of a person in the room or based on detection of a person in the room. For this reason, it can be confirmed from the outside whether or not there is actually a person.

  Here, the notification control means performs control for requesting the operation of the internal closing switch through the internal notification unit, and when the internal closing switch is operated, the notification indicating that the internal closing switch is in use is performed. This is preferably performed by an external notification unit.

  In this aspect, since the person in the room is prompted to operate the internal close switch, the internal close switch can be reliably operated when the person is in the room.

  Further, the notification control means may be configured such that when the external opening switch is operated after a predetermined time has elapsed since the door is closed, the internal closing switch is operated, or by the presence detection sensor. When a person is detected, notification indicating that the person is in use may be performed by the external notification unit.

  In this aspect, the external notification unit can be used as a means for confirming whether an abnormality has occurred in a person who has been in the room for a long time.

  Further, the notification control means indicates absence when a certain period of time has passed since the operation of the internal opening switch or the detection of a person by the occupancy detection sensor without operating the external opening switch. Notification and notification for prompting the external opening switch to be operated again are performed by the external notification unit, and the locking control unit performs the operation of the external opening switch again after the notification by the external notification unit. The door may be unlocked.

  In this aspect, when there is no person in the room and the door cannot be opened from the outside, it is easily recognized that the door is absent, and the door is opened again by operating the external opening switch. Can be opened.

  Further, the internal notification unit has a sound generator, when the lock control means is controlled to lock the door, and when a person is detected by the occupancy detection sensor, You may have a pseudo sound control means which performs control which generates a pseudo sound from the said sound generator.

  In this aspect, a pseudo sound close to the sound generated during use is generated. For this reason, a user can use it in comfort.

  The occupancy detection sensor has a detection area composed of a plurality of areas, and the notification control means detects a person in an area set in advance as an area close to the door passage area in the detection area. When the control of driving the motor is performed by the drive control means in the case where the user is in the vehicle, a notification that calls attention to a person in the room may be performed through the internal notification unit.

  In this aspect, when there is a person in an area close to the passing area of the door, a notification that calls attention is performed. For this reason, it can be set as an automatic door safe for a user including the operator of an operation part.

  Further, the drive control means has an inching operation mode for controlling the drive of the motor so that the door moves in the opening direction or the closing direction only while the internal operation unit or the external operation unit is operated. It may be.

  In this aspect, when the drive control means executes the inching operation mode, the door moves in the opening direction or the closing direction only while the internal operation unit or the external operation unit is operated. For this reason, the drive of the door can be controlled at the will of the user (operator of the operation unit).

  Further, when the control means executes the inching operation mode when a person is detected in an area set in advance as an area close to the passing area of the door among the detection areas, You may make it perform the notification which shows that it is in the inching operation mode, or it switches to the inching operation mode with respect to the person in the said room through an internal alerting | reporting part.

  In this aspect, when the inching operation mode is executed, the user (operator of the operation unit) can know it. Therefore, it is possible to provide an automatic door that is easier for the user to use.

  As described above, according to the present invention, it can be confirmed from the outside whether or not there is actually a person in the room.

It is a block diagram which shows the structure of the control system of the automatic door which concerns on embodiment of this invention. It is a figure for demonstrating the multipurpose toilet provided with the said automatic door. It is the schematic of the state which looked at some indoors of the said multipurpose toilet from the side. It is the FIG. 2 equivalent view explaining the multipurpose toilet of another structure.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the automatic door 10 according to the present embodiment locks the door 12, a motor 14 that drives the door 12, a controller 16 that performs various operation controls including drive control of the motor 14, and the door 12. Electric lock 18, operation units 41 and 42, sensors 46 and 47, and notification devices 51 and 52 for performing notification. The automatic door 10 is installed and used in a multipurpose toilet 24 for use, for example, for wheelchair users, elderly people, pregnant women, mothers with infants, and the like. In addition, although the example installed in the multipurpose toilet 24 (refer FIG. 2) is demonstrated here, it is not restricted to this, It can install in a comparatively narrow room | chamber interior, such as a fitting room.

  As shown in FIGS. 2 and 3, the multipurpose toilet 24 includes a wall portion 27 having an opening 26 that functions as an entrance, and the sliding door type door 12 is disposed in the opening 26. . This wall portion 27 forms a rectangular parallelepiped space together with the other wall portions 28 to 30, and a toilet 32, a wash basin 33, an auxiliary handrail 34 and the like are provided in the room formed by these wall portions 27 to 30. It is arranged.

  A part of the wall 27 in which the opening 26 is formed is configured as a door pocket 38 that houses the door 12 in the open position. That is, the door 12 is movable between a fully opened position where the door 12 is housed in the door pocket 38 and opens the opening 26, and a fully closed position where the door 12 advances from the door pocket 38 and closes the opening 26.

  The operation units 41 and 42 include an internal operation unit 41 disposed indoors and an external operation unit 42 disposed outdoor. The internal operation unit 41 includes an internal opening switch 41a and an internal closing switch. 41b, and the external operation unit 42 includes an external opening switch 42a and an external closing switch 42b. The internal opening switch 41 a and the internal closing switch 41 b are installed on the side surface on the indoor side of the wall portion 27, and are disposed immediately next to the opening portion 26, for example. The external opening switch 42a and the internal closing switch 41b are installed on the side surface of the wall portion 27 on the outdoor side, and are arranged, for example, immediately next to the opening portion 26.

  When operated, the internal opening switch 41a and the external opening switch 42a output a signal for performing control to move the door 12 in the opening direction. When operated, the internal closing switch 41b and the external closing switch 42b output a signal for performing control to move the door 12 in the closing direction. The output of these signals is continuously output while the switches 41a, 41b, 42a, and 42b are being pressed, for example. In order to facilitate disconnection detection, the signal may be continuously output while the pressing operation is not performed, and the signal output may be stopped while the pressing operation is performed.

  An emergency switch 44 is provided in the room. The emergency switch 44 is installed in the vicinity of the toilet bowl 32, for example, and when operated, a contact is made with a predetermined manager such as a management room.

  An occupancy detection sensor 46 and an auxiliary sensor 47 are provided as sensors. The occupancy detection sensor 46 has a detection area 46a, and outputs a detection signal when a person or an object is detected in the detection area 46a. Although not shown, the occupancy detection sensor 46 includes a plurality of sensor units. Then, the detection area 46a can be divided into a plurality of areas, and a person or the like can be detected individually in each divided area.

  The occupancy detection sensor 46 is installed on the ceiling, for example, and irradiates a detection medium such as near infrared rays downward. The detection area 46a has, for example, a rectangular shape when viewed from above, and is set to include at least the vicinity of the toilet 32 and the washstand 33. The detection area 46a also includes an area (safety monitoring area) 46b along the wall 27 where the opening 26 is provided. The safety monitoring area 46b can be set (stored) in advance as an area that can be detected by a person in the vicinity of the passing area of the door 12. As shown in FIG. 4, when the door 12 is configured to move inside the wall 27, the safety monitoring area 46 b includes the vicinity of the door 12 passing area on the door bottom side. An area may be set.

  The auxiliary sensor 47 is a sensor for detecting a person at the opening 26, and is constituted by, for example, a photoelectric sensor. The auxiliary sensor 47 emits a light beam between the door pocket 38 and a portion of the wall portion 27 that faces the door pocket 38 with the opening 26 interposed therebetween, and outputs a detection signal when the light beam is blocked.

  The notification devices 51 and 52 include an internal notification unit 51 and an external notification unit 52. The internal notification unit 51 is a notification unit disposed in the room, and is used to notify a user in the room. The external notification unit 52 is a notification unit arranged outside the room, and is used to notify a user outside the room. The internal notification unit 51 includes an internal sound generator 51 a having a speaker that generates sound (presentation of information) according to the signal output from the controller 16, and a display (information information) according to the signal output from the controller 16. And an internal display 51b that performs (presentation). The external notification unit 52 is also the same, and includes an external sound generator 52a and an external display 52b. That is, the notification devices 51 and 52 include sound generators 51a and 52a and indicators 51b and 52b.

  The controller 16 includes a ROM, a RAM, a CPU, and the like, and exhibits various functions by executing a program stored in the ROM. This function includes drive control means 55, locking control means 56, notification control means 57, and pseudo sound control means 59.

  The drive control means 55 performs drive control of the motor 14 in accordance with operations of the internal operation unit 41 and the external operation unit 42. That is, when the signal output from the internal opening switch 41a or the external opening switch 42a is input to the controller 16, the drive control means 55 controls the drive of the motor 14 so that the door 12 operates in the opening direction. When a signal output from the closing switch 41b or the external closing switch 42b is input to the controller 16, the motor 14 is driven and controlled so that the door 12 operates in the closing direction.

  The drive control of the motor 14 includes a normal mode and an inching operation mode. In the normal mode, if the detection signal from the auxiliary sensor 47 is not input to the controller 16, the motor 14 is driven until the door 12 reaches the fully closed position. In the normal mode, when the signal output from the auxiliary sensor 47 is input to the controller 16, the closing operation is limited.

  The drive control unit 55 switches from the normal mode to the inching operation mode when the internal operation unit 41 or the external operation unit 42 is continuously operated for a predetermined time or longer, for example, 2 seconds or longer. That is, when the opening switches 41a and 42a or the closing switches 41b and 42b are pressed for a moment, the motor 14 is driven and controlled in the normal mode. On the other hand, when the pressing is continued for a predetermined time or longer, the inching operation mode is changed from the normal mode. Switch to. Note that “instantaneous” is expressed as a comparison with the case where the operation is continued for a predetermined time or more, and means that the switch is pressed for a length of time not to enter the inching operation mode. It is. In the present embodiment, the fact that a person is detected in the safety monitoring area 46b is also a condition for switching from the normal mode to the inching operation mode, but this condition may be removed.

  In the inching operation mode, the motor 14 is driven and controlled so that the door 12 moves in the opening direction or the closing direction only while the internal operation unit 41 or the external operation unit 42 is operated. That is, in the inching operation mode, the drive control means 55 performs drive control of the motor 14 while confirming whether or not the signal output from the internal close switch 41b or the like is continuously input to the controller 16. For this reason, while the opening switches 41a and 42a continue to be pressed, the door 12 operates to move in the opening direction. However, once the pressing of the opening switches 41a and 42a is stopped, the door 12 stops. Further, when a predetermined time or more, for example, 5 seconds elapses, or when the opening switches 41a and 42a or the closing switches 41b and 42b are pressed for a moment, the inching operation mode is switched to the normal mode. While the closing switches 41b and 42b continue to be pressed, the door 12 operates so as to move in the closing direction, but once the pressing of the closing switches 41b and 42b is stopped, the door 12 stops. Further, when a predetermined time or more, for example, 5 seconds elapses, or when the opening switches 41a and 42a or the closing switches 41b and 42b are pressed for a moment, the inching operation mode is switched to the normal mode.

  In the inching operation mode, the door 12 may be operated at a moving speed lower than the moving speed of the door 12 in the normal mode, for example, half or less of the normal speed.

  The lock control means 56 controls the drive of the electric lock 18, and controls the electric lock 18 so that the door 12 is locked when the door 12 is closed by operating the internal closing switch 41b. When the signal output from the internal opening switch 41a is input to the controller 16, the electric lock 18 is controlled so that the door 12 is unlocked.

  The notification control means 57 performs control for notifying the user of various information. This notification includes notification for prompting the user to be alerted, notification for prompting the user to perform a predetermined operation, notification for informing the user of the operation status of the door 12, and the like.

  For example, when the person is detected in the safety monitoring area 46b during the closing operation of the door 12 (detected state), the notification for calling attention to the user is a notification that calls attention to the door 12 that is closed. is there. For example, in this notification, a voice “Please be careful about the door to be closed” may be played, or “Intention to the door to be closed!” May be displayed on the internal display 51b. Moreover, you may perform these simultaneously.

  In order to prompt the user to perform a predetermined operation, for example, when the opening switch 41a, 42a or the closing switch 41b, 42b is pressed for a moment, the user can switch to the inching operation mode by long pressing. There is a notice to inform you. In this notification, a voice may be heard saying “If you keep pressing the close switch, you can close the door as long as you keep pressing the switch”, or / and the internal display 51b and the external display 52b have the same contents. The display and the lamp may be turned on / off. In addition, for example, notification that prompts the user to press the internal closing switch 41b or notification that prompts the occupant detection sensor 46 to move the body when the presence of the occupant is confirmed from outside corresponds to this. In this notification, you may hear the voices “You have been confirmed from outside”, “Please press the close switch”, “Please move”, or / and display the same content on the internal display 51b. Also good.

  For example, when the motor 14 is driven and controlled in the inching operation mode, the notification informing the user that the door 12 is operating in the inching operation mode is available. . In this notification, a voice “inching operation is in progress” may be played, or / and the same content may be displayed on the internal display 51b and the external display 52b. In addition, for example, notification that the presence of a room is confirmed, which is performed when the presence of the room is confirmed from the outside, also corresponds. In this notification, a voice saying “Availability is being confirmed” may be played, or / and the same content may be displayed on the external display 52b.

  The pseudo sound control means 59 performs control to generate a pseudo sound from the internal sound generator 51a when the door 12 is locked and a person is detected by the occupancy detection sensor 46.

  Here, the operation of the automatic door 10 according to the present embodiment will be described. First, the basic operation of the automatic door 10 will be described with reference to FIG.

  FIG. 5 is a flowchart for explaining the operation of the door 12 according to a series of flows when the user uses the multipurpose toilet 24. First, when the door 12 is in the fully closed position and is in a standby state. When the external opening switch 42a is turned on (steps ST1 and ST2), the motor 14 is driven to open the door 12 (step ST3). When the user enters the room and presses the internal close switch 41b once (step ST4), the motor 14 is driven to close the door 12 (step ST5). When the door 12 is in the fully closed position, the electric lock 18 is driven and the door 12 is locked, and a display indicating that the door 12 is in use is displayed on the external display 52b (step ST6).

  Thereafter, when the user leaves the multipurpose toilet 24, the user presses the internal opening switch 41a. When the internal opening switch 41a is pressed once (step ST7), the display indicating that it is in use is turned off, and the electric lock 18 is driven to unlock the door 12. Then, the motor 14 is driven to open the door 12 (step ST8). Thereafter, when the external closing switch 42b is pressed once, the door 12 is closed at a normal speed (steps ST9 and ST12). On the other hand, if the external closing switch 42b is not operated even after a predetermined time has elapsed after the door 12 reaches the fully open position, the determination in step ST11 is YES and the motor 14 is driven to close the door 12 ( Step ST10). In this case, since the door 12 is closed without using the closing switch 42b, the door 12 is preferably closed at a low speed.

  Next, a control operation including mode switching will be described with reference to FIG. FIG. 6 is a flowchart when the door 12 is closed. When the user who has entered the room presses the internal closing switch 41b once with the door 12 in the fully open position (step ST21), the area near the door 12 (safety monitoring area) 46b is turned on (detected state). It is determined whether or not there is (step ST22).

  When the safety monitoring area 46b is in the detection state, a notification that alerts the closed door 12 and a notification that it can be switched to the inching operation mode are notified (steps ST23 and ST24). For example, the internal display 51b displays “Caution on the door to be closed!” And also displays “If the switch is kept pressed, the door can be closed only while the switch is kept pressed.” Then, it is determined whether or not the internal closing switch 41b is kept pressed for a predetermined time or more (step ST25). When the internal closing switch 41b is kept pressed for a predetermined time or more, the inching operation mode is switched.

  In the inching operation mode, the door 12 is operated while determining whether or not the internal closing switch 41b is turned on. That is, if the close switch 41b is on (YES in step ST26), the door 12 is closed at a low speed during that time, and “Inching operation is in progress” is displayed on the indicators 51b and 52b (step ST27). , ST28). The motor 14 is driven while monitoring the state of the closing switches 41b and 42b until the door 12 reaches the fully closed position (step ST29). When the door 12 reaches the fully closed position, the electric lock 18 is driven to lock the door 12. (Step ST30). As a result, the inching operation mode is canceled, and when the opening switches 41a and 42a are subsequently turned on, the normal mode is set.

  On the other hand, before the door 12 reaches the fully closed position, when the pressing of the closing switches 41b and 42b is stopped and the door 12 is not turned on, the process proceeds to step ST31 and the driving of the motor 14 is stopped. Thereby, the closing operation of the door 12 is stopped. At this time, the display of “inching operation is being performed” on the indicators 51b and 52b is stopped (step ST32).

  When the safety monitoring area 46b is not in the detection state, the determination in step ST22 is NO. Therefore, the process proceeds to step ST33, and the process is fully closed unless the detection signal from the auxiliary sensor 47 is input to the controller 16. Move the door 12 to the position.

  Next, referring to FIG. 7, a control operation when generating a pseudo sound during use will be described. When the door 12 is closed and locked by the electric lock 18, the process proceeds from step ST41 to step ST42. In step ST42, it is determined whether the occupancy detection sensor 46 detects a person. If a person is detected, control is performed to generate a pseudo sound (step ST43). Therefore, while the door 12 is locked and it is determined that there is a person in the room, a pseudo sound similar to the sound generated when the toilet is used is generated.

  Next, referring to FIG. 8, the control operation (control operation of the knock function) when confirming occupancy from the outside will be described. This figure shows the control operation when the door 12 is closed and the door 12 is locked by the electric lock 18. In this state, it is determined whether or not the operation of the external opening switch 42a has been performed (step ST51). When the external opening switch 42a is turned on, the internal notification unit 51 presents information for checking the presence of the room ( Step ST52). For example, the internal sound generator 51a plays a sound such as “has been confirmed from the outside”, “push the close switch”, “move”. In addition, the external notification unit 52 presents information indicating that the presence in the room is being confirmed (step ST53). For example, the external sound generator 52a plays a sound “Checking in-room”.

  Then, it is determined whether the internal closing switch 41b has been operated or the detection state of the occupancy detection sensor 46 has changed (steps ST54 and ST55). The internal notification unit 51 notifies the outside that it is in use (steps ST56 and ST57). For example, a voice “currently in use” is played from the external voice generator 52a, and a voice “notified that it is currently used” is sent from the internal voice generator 51a.

  On the other hand, when the internal closing switch 41b is not operated and the detection state of the occupancy detection sensor 46 does not change, the process proceeds from step ST55 to step ST58 to determine whether or not a predetermined time has elapsed. To do. Here, the reason for waiting for the elapse of the predetermined time is that the user does not always immediately operate the internal closing switch 41b when the presence confirmation request is made. If the internal closing switch 41b is not operated within the predetermined time and the detection state of the occupancy detection sensor 46 does not change, the external notification unit 52 notifies the absence and the external opening switch 42a. Notification is made to prompt the user to operate again (step ST59). Further, the internal notification unit 51 notifies that the operation of the external opening switch is valid (step ST60). Notifications at this time are, for example, “currently absent”, “please press the opening switch again”, “the door opens by operating the external opening switch”, and the like.

  When the external opening switch 42a is operated, the electric lock 18 is unlocked and the door 12 is opened (steps ST61 and ST62).

  The control operation of the knock function may be executed after a predetermined time has elapsed after the door 12 is closed and locked. For example, when a cared person who is accompanied by a caregiver uses the multipurpose toilet 24, the caregiver may wait outside for a long time. In this case, since the caregiver urges the operation of the internal closing switch 41b by pressing the external opening switch 42a, it can be confirmed whether there is any abnormality in the cared person inside. When the cared person is in an abnormal state in which the internal closing switch 41b cannot be pressed, the door 12 can be opened by pressing the external opening switch 42a again.

  As described above, in the present embodiment, when the internal closing switch 41b is operated or a person is detected by the occupancy detection sensor 46, a notification indicating that the user is in use is displayed on the external notification unit 52. Made by. That is, it is notified that the device is in use based on the action of a person in the room or based on the fact that the person in the room is actually detected. For this reason, it can be confirmed from the outside whether the multipurpose toilet 24 actually has a person.

  Moreover, in this embodiment, since the internal notification unit 51 is requested to operate the internal closing switch 41b, a person in the room is prompted to operate the internal closing switch 41b. For this reason, when a person is in the room, the internal closing switch 41b can be reliably operated.

  Further, in the present embodiment, when a predetermined time or more elapses after the operation of the external opening switch 42a without operating the internal closing switch 41b and detection of a person by the occupancy detection sensor 46, a notification indicating absence Since the notification that prompts the user to operate the external opening switch 42a is performed again, the user may be absent when the door 12 cannot be opened from the outside despite the absence of a person in the room. The door 12 can be opened easily by re-operating the external opening switch 42a.

  In the present embodiment, a pseudo sound is generated when the door 12 is locked and a person is detected by the occupancy detection sensor 46. For this reason, a user can use it in comfort.

  Moreover, in this embodiment, when the door 12 is operated when there is a person in an area (safety monitoring area) 46b close to the passing area of the door 12, a notification that calls attention is given. For this reason, it can be set as an automatic door safe for a user including the operator of an operation part.

  In the present embodiment, when the drive control means 55 executes the inching operation mode, the door 12 moves in the opening direction or the closing direction only while the internal operation unit 41 or the external operation unit 42 is being operated. For this reason, the drive of the door 12 can be controlled by a user's (operator of an operation part) will.

  Further, in this embodiment, when switching from the normal mode to the inching operation mode, the notification devices 51 and 52 notify that the mode is switched to the inching operation mode, so the user (operator of the operation units 41 and 42) You can know that the mode changes. Therefore, it can be set as the automatic door 10 which is easier to use for the user.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention. For example, although the door 12 can be locked by the electric lock 18 in the above embodiment, the present invention is not limited to this. For example, while the electric lock 18 is omitted, the door 12 may not be opened by the locking control unit 56 invalidating the operation of the external opening switch 42a under a predetermined condition. In this case, a mechanical lock may be provided.

  In the above embodiment, the inching operation mode can be executed in both the opening operation and the closing operation. However, the present invention is not limited to this, and the inching operation mode can be executed only in one of the opening operation and the closing operation. It is good also as a structure. For example, when the door 12 is stored in the door pocket 38 as in the above embodiment, the inching operation mode may not be executed during the opening operation.

  In the above embodiment, one of the conditions for switching to the inching operation mode is set when a person is detected in the safety monitoring area 46b. However, in the configuration in which the safety monitoring area 46b is not set, the auxiliary sensor 47 sets the person. Detection may be added as a switching condition.

  Moreover, in the said embodiment, although it was set as the structure which has the room presence detection sensor 46 installed in the ceiling, and the auxiliary sensor 47 installed in the wall part 27, it is not restricted to this structure. For example, it is good also as a structure which has only the auxiliary sensor 47 installed in the wall part 27. FIG. In this case, based on the time series change of the photoelectric sensor installed on the wall 27, for example, if it is detected only once from the initial state, it will be in the room, if it is detected twice, it will be exited. It is also possible to detect a room and use it as an in-room detection sensor.

  Further, the embodiment may further include a remote switch. The remote switch is connected to the controller 16 by wire or wirelessly, and can be installed at any place of the multipurpose toilet 24.
