Description

Long-term stay restraining device for concealed toilet room on the back of the ceiling

The present invention relates to a long-term stay restraining device for a concealed toilet room on the back of a ceiling that can be applied to a toilet such as a public toilet or an office toilet.

In recent years, there has been a problem that toilet rooms in public toilets or office toilets are occupied by users for a long time. The background is due to the popularity of smart phones and portable game consoles and the speed of data communication, so the use of the toilet room as a business-independent operation using smart phones and portable game consoles (joining SNS and online games) Etc.) or access to information without urgency, the use of the toilet room into a private space to lead to longer time.

Therefore, even when a plurality of toilet rooms are provided in the toilet, it is easy to change the state in which all the toilet rooms are in use, and it is a situation in which a person who wants to go to the toilet cannot use the toilet room.

With regard to such a problem, Patent Document 1 proposes a scheme of notifying a user in a toilet room that there is a person waiting for a vacancy. Patent Document 1 discloses a technique in which a wall surface or the like in a toilet is provided with a device that detects a presence or absence of a waiting space in a contact or non-contact manner, and a display that is interlocked with the device is provided in the toilet room. When a person waiting for a vacancy is detected, a person in the toilet room is used to notify a person waiting for a vacancy.

Further, Patent Document 2 discloses a technique in which a sensor for detecting presence or absence of a human body in a toilet room is provided, which is not provided in a toilet in which a plurality of toilet rooms are arranged, but is suitable for a multi-function type in which an automatic door is installed. Toilet room to prevent homeless people from occupying the toilet room for a long time, occupying the toilet room for mischief or criminal purposes, and in order to easily find people falling in the toilet room due to unexpected accidents, etc. When the continuous human body detection state continues for a set time or longer, the automatic door is unlocked and the automatic door is opened.

Further, Patent Document 3 discloses a technique of detecting a human body and performing a determination as to whether or not a person is present in the toilet room, causing the electric wave to contact the human body, particularly the chest, and using the reflected wave of the electric wave due to the motion caused by the heart rhythm of the chest and the breathing. The Doppler effect produced in it.

In a toilet (toilet) such as a public toilet or an office toilet, when it is desired to detect the presence or absence of a human body in the toilet room, the method exemplified in Patent Document 3 is considered to be easy to adopt because of its simple structure.

However, in practical products such as a non-contact biological information monitoring device that utilizes the Doppler effect, the setting conditions of the signal transceiver that radiates microwaves and receives reflected waves of microwaves are almost all parts of the signal transceiver. Install as much as possible on the outside of the wall or ceiling to obtain high-precision biological information (heart rhythm, breathing, body movements, etc.) as the main purpose.

For example, there is an actual product in which it is assumed that a person who searches for a survivor at the time of a disaster is targeted to a person as large as possible (search target). In addition, in a medical institution or a nursing facility, in order to prevent neglect of a person who falls from a bed, it is assumed that a person lying on the periphery of the bed is targeted. In addition, for the purpose of caring for the elderly living alone, one person is expected to be present in any part of the entire room.

As a solution related to the above care, a plurality of sensors are used to construct the detection system, and Patent Document 4 proposes a scheme of the home security remote confirmation system. Patent Document 4 discloses a human body detecting sensor using a microwave-based Doppler effect, and discloses a concealed human body detecting sensor disposed on a back surface of a ceiling including a residential toilet, and the concealed type The human detection sensor is covered by the ceiling components.

Patent Document 1: Japanese Patent Laid-Open Publication No. 2015-218571

Patent Document 2: Japanese Patent Laid-Open Publication No. 2002-188204

Patent Document 3: Japanese Patent Laid-Open Publication No. 2002-071825

Patent Document 4: Japanese Patent Laid-Open Publication No. 2002-024966

In the above-mentioned environment such as a public toilet or an office toilet, a plurality of toilet rooms are usually arranged. Further, in order to be able to grasp whether or not there is any person in each of the toilet rooms, it is necessary to satisfy the following conditions when it is desired to use not only a sensor using the Doppler effect but also various sensors.

First, it is necessary to set the device using the sensor to correspond to each toilet room. In particular, when a person is placed in a very narrow space such as a toilet, and the toilet room is usually arranged adjacently, the installation place of the device for radiating the microwave for receiving the reflected wave by the Doppler effect cannot be It is the side wall or floor of the toilet, but only the ceiling.

In addition, in the case of a women's toilet, it is necessary to be seen by a person who is in the toilet room to eliminate insecurity. That is, if it is misunderstood as a sneak camera, it will give a distrust of the facility manager.

As described above, there is a problem that a device that is visually unobstructed between a sensor such as a photo sensor, a human body temperature sensor, and an infrared sensor and a detection target cannot be used.

In the technique disclosed in Patent Document 3, since the microwave is radiated and the Doppler effect of the reflected wave and the received reflected wave is utilized, it is considered that the presence or absence of the human body in the toilet room can be grasped.

However, humans who have brought a smart phone or a portable game machine into the toilet to play games or obtain information, and who use the original usual use in the toilet are indiscriminately tested. Therefore, for a person who stays in the toilet room for a long time for a purpose different from the original use, the effect of vacating the toilet room cannot be expected by this technique.

Therefore, in view of the above problems, an object of the present invention is to detect the presence or absence of a human body in a toilet room, and to alert a person in the toilet room to possessive use, and an object of the present invention is to achieve proper utilization of the toilet room. (Invention of the first aspect)

The present invention has been made in view of the above problems, and has provided the following ceiling back concealed type toilet long-term stay suppressing device, thereby solving the above problems. The ceiling-side concealed toilet room long-term stay restraining device comprises: a detecting mechanism for detecting a human body in the toilet room; a reminding mechanism including a sounding device capable of outputting a sound-based reminder to the toilet room; and a control mechanism based on the detecting mechanism The human body detects to control the output of the reminder of the reminding mechanism; the frame body internally houses the detecting mechanism, the reminding mechanism and the control mechanism, and the lower surface of the frame body serves as a ceiling piece above the toilet room a mounting surface on the back of the ceiling, wherein the detecting mechanism comprises a Doppler sensor, and the Doppler sensor radiates microwaves passing through the ceiling member into the toilet room and detects by Doppler effect The biological information of the human body in the toilet room, the control mechanism includes a timer, and the timer measures the time of treating the toilet room based on the detection of the biological information by the detecting mechanism, when the timer measures The control mechanism causes the reminder mechanism to output the reminder when the time between the toilets exceeds a predetermined time. (Invention of the second aspect)

Further, in the present invention, preferably, the reminder based on the sound is a reminder based on the sound information, and the sounder of the reminding mechanism outputs a reminder based on the sound information that penetrates the ceiling member toward the toilet room. (Invention of the third aspect)

Further, in the present invention, preferably, when the detecting means detects a change in the biological information based on the reduction of the body motion, the control means causes the timer to start the measurement of the time between the toilets, wherein the body The reduction in the movement is caused by the change in the seating movement of the human body entering the toilet seat and sitting in the toilet seat, and the sitting posture of the human body sitting on the toilet seat is maintained. (Invention of the fourth aspect)

Further, in the present invention, it is preferable that a mounting surface of the frame body is provided with a microwave passage surface and a through hole, and the microwave passes through a radiation wave of the microwave radiated from the surface for the detecting mechanism and a reflected wave of the microwave of the radiation. The sound passing through the through hole for the reminding mechanism passes, and when the mounting surface of the frame overlaps the back surface of the ceiling of the ceiling member, the microwave passing surface and the through hole are covered by the ceiling member. (Invention of the fifth aspect)

Further, in the invention, the mounting surface of the frame body is provided with a fixing mechanism for fixing the frame body to the back surface of the ceiling of the ceiling member. (Effects of the first aspect of the invention)

When the person plays a smart phone or a portable game machine in the toilet room, the time occupied by the toilet (the time between the toilets) is significantly longer than the time when the person usually uses the toilet room.

Therefore, according to the invention of the first aspect, it is possible to give a reminder to a person who occupies the toilet room at a predetermined time or more that is arbitrarily set in advance, and therefore has an effect of easily vacating the toilet room.

Further, since it is set to emit a reminder by the sound outputted by the reminder mechanism, it is effective in being able to reliably transmit a reminder to a person who is in the toilet room.

Since the long-term stay restraining device of the concealed toilet room on the back of the ceiling is disposed on the back of the ceiling, the person entering the toilet room cannot see the long-term stay restraining device of the concealed toilet room on the back of the ceiling even if the ceiling is observed.

Therefore, there is no misunderstanding that the device for sneak shots is installed, and the person entering the toilet room does not feel insecure. (Effect of the second aspect of the invention)

According to the invention of the second aspect, the reminder outputted from the sound generator is sound information, so that the person who receives the reminder in the toilet room can immediately understand that the reminder content is intended to leave the toilet room, and the effect of leaving the toilet room is improved. (Effect of the third aspect of the invention)

For a person entering the toilet room, it is a normal behavior to temporarily hold the sitting position after sitting on the toilet seat. That is, the body movement is reduced from a large movement such as sitting in the toilet to a small movement such as maintaining the sitting posture. Therefore, according to the invention of the third aspect, the detecting means detects the change of the biological information based on the decrease in the body motion, and starts measuring the time between the toilets. Further, even when sitting on a toilet seat and operating a portable terminal such as a game machine or a smart phone, the body's body motion itself becomes small, and a change in biological information based on a decrease in body motion is also detected.

Therefore, it is possible to have an excellent effect of being able to reliably start the measurement of the time between the toilets for the toilet room in which the portable terminal is used instead of occupying the toilet room.

In addition, even if the person who wants to enter the toilet room and the person who leaves the toilet room pass by the door of the toilet room and enter the toilet room, and perform the action of seating on the toilet seat for the sake of urine and urine, by detecting Based on the change in the biological information of the above-mentioned body movement that has entered the toilet, the measurement of the time between the toilets is started, thereby preventing the metering of the time between the toilets of the person who has previously left the toilet room. (Effect of the invention of the fourth aspect)

According to the invention of the fourth aspect, the microwave passage surface and the through hole are in contact with the ceiling member and covered by the simple operation of arranging the ceiling back concealed type toilet long-term stay suppressing device on the back side of the ceiling of the ceiling member, on the back of the ceiling. After the setting, the small animal or the like does not enter between the device and the ceiling member, and in addition, dust or small foreign matter on the back surface of the ceiling can be prevented from being mistakenly inserted into the device.

In addition, the sound-based reminder has a directivity directed downward from the reminder mechanism and is played through the through hole to the toilet room. Moreover, if the through hole is open between the through hole and the ceiling member, the sound-based reminder diffuses from the space to the space on the back of the ceiling, and it is difficult to reach the toilet room below the ceiling member. However, in the invention of the fourth aspect, as described above, the through hole is in contact with and covered by the ceiling member by being disposed on the back side of the ceiling of the ceiling member, so that the sound-based reminder is appropriately passed from the through hole through the ceiling member to the proper position. The space in the toilet room below the installation location of the device serves as a reliable transmission to the person in the toilet room to be reminded. (Effect of the fifth aspect of the invention)

According to the invention of the fifth aspect, the ceiling-side concealed toilet room long-term stay suppressing device can be stably installed on the back side of the ceiling of the ceiling member, and the small-scale earthquake can be prevented even if the building does not collapse. The effect of device misalignment.

The invention will now be described in accordance with the illustrated embodiments. Fig. 1 is a view showing the installation state of the ceiling back concealed type toilet long-term stay suppressing device 1 of the present invention. As shown in Fig. 1, a ceiling member C of the toilet A is extended above the toilet room B of the toilet (toilet) A.

Moreover, the ceiling member C is a member having less penetration loss of microwaves, for example, a sheet of gypsum board used as a conventional ceiling finished product. Further, in the ceiling-side concealed toilet room long-term stay suppressing device of the present embodiment, it is verified that the radiation wave and the reflected wave of the microwave emitted from the device described later are even if the thickness of the ceiling member is 18 mm. It can also penetrate without any problem, and the device can operate properly.

In the public toilet or office toilet, the ceiling member C of the toilet A uses a large number of the above-mentioned components composed of gypsum board, and the ceiling of the toilet A is usually covered by the ceiling finished product with less penetration loss of the microwave. Further, in the toilet A of Fig. 1, a toilet room B is shown, but a plurality of toilet rooms are arranged side by side in the front-rear direction in the drawing, and only one toilet room B is shown for convenience of explanation.

As shown in the drawing, the ceiling back concealed toilet room long-term stay suppressing device 1 of the present invention is disposed on the ceiling member C in such a manner as to be placed above the body E of the toilet seater sitting on the toilet seat D of the toilet bowl. The back of the ceiling. Further, each of the toilets B is correspondingly provided with a ceiling back concealed type toilet long-term stay suppressing device 1.

The ceiling back concealed toilet room long-term stay suppressing device 1 is configured such that the detecting mechanism 2, the alerting mechanism 3, and the control mechanism 4 are incorporated in the casing 5. (testing facility)

The detecting mechanism 2 is constituted by a Doppler sensor, and the Doppler sensor radiates a chamber B that can penetrate the ceiling member C toward the toilet room B located below the installation place of the long-term stay restraining device 1 of the concealed toilet room on the back of the ceiling. The microwave is used to detect the presence or absence of human body E in the toilet room B and the biological information described later by using the microwave-based radiation wave and the Doppler effect of the reflected wave. Further, the detecting mechanism 2 is provided to detect the human body E of the user who enters and exits the toilet room B by using the entire area in the toilet room B including the position of the door F of the toilet room B as the detection range.

The Doppler sensor of the detecting mechanism 2 has the ability to detect the heart rhythm and breathing of the human body existing in the detecting area, and has the ability to detect the body motion of the human body existing in the detecting area, which is detected by the above-mentioned heart rhythm and breathing A sensor for biological information composed of body movements.

The body movements of the human body include: movements when opening and closing the door of the toilet room to enter and exit the toilet room; actions of pulling down or lifting pants, skirts, underwear, etc.; sitting on the toilet seat or getting up from the toilet seat; sitting in the toilet seat state Take the action of taking the toilet paper; and sit on the toilet seat and operate the small fingertip movement of the portable terminal device such as a smart phone or a portable game machine.

Therefore, the Doppler sensor can detect not only the state in which the body moves in the toilet room, such as up, down, left and right, and back and forth, but also the ability to detect that the person is sitting in the toilet seat for the toilet or the fingertip. The state in which the body movement of the terminal device is small, thereby detecting not only the presence or absence of biological information (heart rhythm, breathing, body movement) (ie, detecting the presence or absence of a human body), but also detecting biological information based on changes in biological information that are reduced in body motion and small body movements ( Bioinformation based on small movements such as heart rate, pulse, fingertips, etc., and changes in biological information based on increased body movements.

Further, in the space on the back surface of the ceiling, for example, the vibration generated by the ventilating fan, the vibration of the air conditioning duct, or the vibration passing through the wall from the outside of the building is easily transmitted, and the Doppler sensor of the above detecting mechanism 2 erroneously oscillates these vibrations. The possibility of erroneous detection is received as a reflected wave from the toilet side. Therefore, in order to prevent erroneous detection due to vibration from the space side on the back surface of the ceiling, it is preferable to provide a defense mechanism composed of an impact absorber or the like around the detection mechanism 2. (Reminder agency)

The reminder mechanism 3 is provided with a sounder capable of outputting a reminder based on the sound information toward the toilet room B located below the long-term stay restraining device 1 of the concealed toilet room on the back of the ceiling. The reminder based on the sound information is composed of a human voice, a synthesized sound, or the like, and is stored in the reminding mechanism 3 in a manner that can be issued when necessary. The content of the sound information is, for example, "the remaining one minute to the time. In order to wait for the next one, please prepare to leave the toilet room" and other reminders to leave the toilet room.

The sound data is set to be issued by the reminding mechanism 3, and the reminder generated by the sound data causes the entering toilet room who is in the state of the toilet room B to be in the toilet room B for a predetermined period of time to leave the toilet room, so that the toilet is required to enter the toilet. Everyone can hear it. However, assuming that there is a waiter waiting for the toilet room to vacate in the toilet, it is preferable that the waiter can also hear the volume of the sound data.

That is, if the waiter waiting outside the toilet room can also hear the reminder based on the voice information, the waiter can know the next free toilet room according to the time information, thereby reducing the physiological pain.

The sound information is listed as a sound for reminding the person to be left in the toilet room to leave the toilet room. However, the present invention is not limited to the sound information, and may be a sound such as a time sound or a warning sound. That is, the person who treats the toilet room can be reminded that various sound effects can be used when leaving the booth from the toilet room. (control agency)

The control mechanism 4 is connected to the above-described detecting mechanism 2, and is provided to be capable of receiving biometric information of the human body E detected by the detecting mechanism 2 including whether or not the toilet is to be in the toilet. Further, there is a timer 6 that measures the time between the toilets based on the biological information of the human body detected by the detecting mechanism 2.

Further, the control mechanism 4 is connected to the above-described reminding mechanism 3, and the control mechanism 4 controls the reminding mechanism 3 to output the sound information as the above-mentioned reminder when the time between the toilets measured by the timer 6 exceeds a predetermined time (for example, 10 minutes). (Appropriate access to the toilet room, leaving the toilet room)

Specifically, when a person opens the door F into the toilet room B, the detecting mechanism 2 performs detection as follows: from the detection range in which the person enters the detecting mechanism 2, the detecting mechanism 2 detects the human body moving from the opened door to the toilet bowl And detecting the movement of the human body into the toilet until the person entering the toilet room takes off the pants, skirt or underwear and sits on the toilet seat D. Since the body motion of the person at this time is large, the detecting mechanism 2 that detects the human body transmits the biological information based on the large body motion to the control unit 4.

Next, in the case where the portable terminal device is operated while sitting or seated on the toilet seat D, the detecting mechanism 2 also detects biological information composed of the heart rhythm, breathing, and body motion of the human body. Further, in this case, since the sitting posture maintaining operation is performed, the human body movement is small, and therefore the detecting mechanism 2 transmits the biological information based on the small body motion to the control unit 4.

In this way, when the seating movement from the human body to the toilet is changed to the seating posture of the human body sitting on the toilet seat and the body movement is greatly reduced, the detecting mechanism 2 also detects the change of the biological information based on the reduction of the body movement and controls the movement. Agency 4 sends.

When the biometric information of the human body is changed as the information is transmitted from the detecting unit 2 to the control unit 4, the control unit 4 determines that the human body E has changed from the entering toilet to the sitting posture maintaining operation based on the change in the biological information. When this determination is made, as described above, the control mechanism 4 causes the timer 6 to start the measurement of the time between the toilets, and the time between the metered toilets and the preset standby time for the reminder mechanism to operate. That is, the time is compared for comparison.

When the person in the toilet room B finishes the urination and the like and enters the preparatory movement for leaving the toilet room B within the predetermined time period, the body movement is inevitably increased because the clothes and the like are arranged from the toilet seat. The movement of opening the door F and leaving the toilet room B is also a large body movement. Therefore, the biological information detected by the detecting mechanism 2 is based on the state in which the body motion is increased from the time of leaving the toilet preparation operation to leaving the toilet room.

Moreover, when the person closes the door F and leaves the toilet room B, since the human body does not exist in the detection range of the detecting mechanism 2, the detecting mechanism 2 detects the state without biometric information (biological information is "zero"), and the control mechanism 4 The side receives the above information, and changes the biological information based on the large body movement from the toilet to the case where the biological information in the biological state is not detected as the signal is sent from the detecting mechanism 2 to the control mechanism 4, and the control mechanism 4 determines the toilet room. It is an empty toilet room. (measurement reset)

When a determination is made to leave the toilet room detection (determining that the toilet room is an empty toilet room), the control mechanism 4 causes the timer 6 to reset the time of the toilet room (set the time between the toilets to zero), and It becomes the state of the metering start standby. In this case, since the toilet room is left within the prescribed time, the reminder mechanism 3 does not operate. (Entering the toilet room after leaving the toilet room)

In the case where the next person enters the toilet room B after a person has left the toilet room B, as described above, the detecting mechanism 2 performs the above-mentioned entry into the toilet room for the next person (to enter the toilet room, undress, sit down) Tested on the toilet seat, etc.). As described above, when the detecting means 2 detects that the biological information in the toilet B is zero due to the above leaving the toilet room, the timer 6 returns to the state in which the metering start standby.

Therefore, even if a person enters the toilet room B only after a short time after leaving the toilet room, the measurement of the time of the room to be opened by the former person in the toilet room B does not continue. Then, the next person's entering the toilet seat seating operation is changed to the sitting posture maintaining operation, and the detecting mechanism 2 also detects the change in the biological information based on the reduction in the body motion, and transmits the detected change in the biological information to the control unit 4. Further, if the control mechanism 4 determines that the entering the toilet holder has changed from the entering toilet to the sitting posture maintaining operation, as described above, the timer 6 starts and starts the measurement of the time between the toilets. (When the time between toilets exceeds the specified time)

The continuous posture is based on the small movement of the human body in the toilet room B or the detection of the heart rhythm or the breathing, and the detection mechanism 2 can detect the movement of the human body. When the seating posture continues to operate, the control mechanism 4 When it is determined that the time between the toilets measured by the timer 6 exceeds the predetermined time, the control unit 4 operates the reminding mechanism 3 to transmit a reminder based on the sound information to the person in the toilet room B, prompting him to leave. In the toilet or out of the toilet. (Successfully leaving the toilet room and entering the toilet room)

The next person in the case where the person who previously used the toilet room leaves the toilet room and then enters the toilet room, the detecting mechanism 2 detects the biological information based on the person leaving the toilet room (the large body movement) and based on entering the toilet The biometric information of the intervening person entering the toilet seat (large body movement) is in a continuous state, and it is possible to transmit the signal from the detecting mechanism 2 to the control mechanism 4 as a state in which the biological information based on the large body motion is continuously detected. That is, when the current person leaves the toilet room, there is a possibility that the meter reset will not be performed without detecting the biological information, so the timer 6 does not return to the state of the metering start standby.

However, the movement of the person who enters the toilet room also changes from the movement to the toilet seat to the seating posture that is seated on the toilet seat. Therefore, the detecting mechanism 2 detects the change of the biological information based on the reduction of the body motion and the control mechanism 4 send. Further, when the state in which the body movement is greatly reduced is transmitted as the signal from the detecting means 2 to the control means 4, the control means 4 determines that the person entering the toilet room has changed from the entering the toilet seat to the sitting posture maintaining operation, and is to be treated. The metering of the time between the toilets is reset, and returns to the state in which the meter 6 starts the standby, and then the timer 6 is started to measure the time between the toilets as described above.

That is to say, it is assumed that "the timer is returned to the metering start standby state because the previous person has not detected the human body after leaving the toilet room" and "the former person leaves the toilet room and the latter person enters the toilet room continuously, and the latter person enters the toilet. In the case where the time between the toilets of the previous person continues to be measured, the control mechanism 4 is set to be in any case, and if the above determination is made, the timer 6 is reset at the time of the determination. The measurement of time, and return to the state of the metering start standby, and then the measurement of the time between the toilets. Thereby, the measurement of the time of the waiting room is appropriately started for the latter person entering the toilet room.

As shown in FIG. 4, the transmission of the biological information from the detecting means 2 toward the control means 4 can be transmitted, for example, at the level of the Doppler effect, and the control means 4 is set to change based on the level of the Doppler effect received as a signal. The amplitude determines whether it is an empty toilet, whether it is a state of entering the toilet seat, whether it is a state of maintaining the seated posture, and whether it is a state of leaving the toilet. Further, the method of transmitting the biological information as a signal from the detecting means 2 to the control means 4 or the method of determining the state of the person to be occupant based on the received signal (i.e., biological information) is not particularly limited. In Fig. 4, the vertical axis is the level of the Doppler effect, and the horizontal axis is the time. (framework)

FIG. 2 schematically shows a state in which the casing 5 accommodates the detecting mechanism 2, the alerting mechanism 3, and the control mechanism 4. As shown in FIG. 2, the lower surface (the lower surface of the casing) of the casing 5 is a mounting surface 7 that is in close contact with the back surface of the ceiling of the ceiling member C.

Further, as shown in (b) of FIG. 3, the microwave passing surface 8 and the plurality of aligned through holes 9 are located on the mounting surface 7, and the microwave passing surface 8 and the through hole 9 are disposed at a position where the back of the ceiling is concealed When the long-term stay restraining device 1 of the toilet room is mounted on the back surface of the ceiling of the ceiling member C, the microwave passing surface 8 and the through hole 9 are covered by the ceiling member C.

The microwave passage surface 8 is a region in the lower plate surface of the casing, and is a portion through which the radiation wave of the microwave radiated by the detecting mechanism 2 and the reflected wave of the radiated microwave pass. Further, the upper surface of the lower panel of the frame in which the through holes 9 are arranged is provided with a sounding device (for example, a speaker) 10 of the reminding mechanism 3, and the sound information outputted by the reminding mechanism 3 passes through the through holes 9 and further passes through the ceiling member C. The person in the toilet room B below can hear it. (About loading the reminder mechanism and covering the through hole by the ceiling piece)

The reason why the above-described reminding mechanism 3 is loaded into the casing 5 together with the detecting mechanism 2 and the control mechanism 4 is as follows. First of all, assuming that the reminder mechanism is separately disposed at a position such as an inner wall surface in the toilet room that can be seen by the toilet person, since the reminder mechanism reminds the person in the toilet room that the toilet room is to leave the toilet room, it is easy to affect the waiting The mood of the person in the toilet. Moreover, it is expected that the person in the toilet will perform a trick on the reminder institution or destroy the reminder institution.

In order to prevent the reminder mechanism from being mischievous or destroyed, it is listed as a countermeasure to lie in the back of the ceiling above the toilet room B. However, in the case where the reminding mechanism is configured to be separately hidden on the back of the ceiling, the sound emitted by the reminding mechanism is suffocated on the back of the ceiling, and the sound quality of the sound passing through the ceiling member to the lower toilet room is deteriorated.

Thus, if the sound quality is deteriorated, the content of the reminder cannot be transmitted to the person in the toilet room to be in the toilet. For example, even if the sound information is broadcasted by a foreign language such as English or Chinese to remind the toilet room to leave the toilet room, not only the content of the broadcast is unclear, but even if it is played in Japanese or in a foreign language, it cannot be distinguished.

In order to reliably convey the content of the reminder, it is considered to increase the volume of the reminder mechanism. However, if the volume is increased, the ceiling surface of the toilet is vibrated in a wide range, and it is unclear which toilet room is being reminded. Therefore, for the person in the toilet room as the object of reminding, it is impossible to judge whether to remind the user to leave the toilet room or to remind the person in the adjacent toilet room, for the adjacent toilet room that is not the object of the reminder. For people, it is also impossible to judge whether the object of the reminder is itself. Therefore, there is a problem that any person who is to be in the toilet room is likely to cause misunderstanding.

In addition, for the waiter who waits outside the toilet room to vacate the toilet room, it is difficult to judge which toilet room is being reminded, only to hear the reminder during the play and leave the toilet room, and can not expect the toilet room to be vacated immediately. . (Benefit to the reminder mechanism)

In order to solve the above problems, firstly, in the concealed toilet room long-term stay suppressing device 1 on the back side of the ceiling, as described above, the reminding mechanism 3 is loaded into the frame 5 together with the detecting mechanism 2 and the control mechanism 4, and the back side of the ceiling is concealed. The toilet room long-term stay suppressing device 1 is disposed on the back side of the ceiling of the ceiling member C, whereby the reminding mechanism 3 can be simply hidden on the back surface of the ceiling without the need to separately provide the reminding mechanism 3 to the back of the ceiling. (The benefit of covering the through hole by the ceiling piece)

Next, the reminder based on the sound information is outputted from the above-described reminding mechanism 3 with the directivity directed downward, and is played through the through hole 9 into the toilet room B. Further, by placing the ceiling back concealed type toilet long-term stay suppressing device 1 on the back side of the ceiling of the ceiling member C, the through hole 9 is in contact with the ceiling member C and covered, so that the reminder based on the sound information is not boring on the back of the ceiling.
