Description

Aspects of the present invention generally relate to bathroom exit detection systems.

Because the bather does not know when to leave the bathroom, for example, the bather and other family members run into each other in the dressing room, the timing to start preparing meals for the bather is unknown, and the dressing room Various problems may occur in the home, such as not being able to operate heating at appropriate timing.

For example, it has been proposed to detect a bather's exit from the bathroom using a human body detection sensor (for example, Patent Document 1). However, detecting the bather's exit from the bathroom is too late, and there is a possibility that it will be too late to suppress the collision in the dressing room or heat the dressing room in time.

Further, for example, it has been proposed to issue a notification by transmitting information on leaving the room through the operation of the bather (for example, Patent Literature 2). However, in this case, if the bather forgets to operate, the notification will not be performed.

For this reason, in the bathroom exit detection system, by predicting the exit of the bather from the bathroom and activating the equipment outside the bathroom, it is possible to more reliably suppress collisions in the dressing room and to improve the heating of the dressing room. It is desired to be able to start at an appropriate timing.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same reference numerals are given to the same constituent elements, and detailed description thereof will be omitted as appropriate.

(First embodiment)
FIG. 1 is a block diagram schematically showing the bathroom exit detection system according to the first embodiment.
As shown in FIG. 1 , the bathroom exit detection system 10 includes a remote controller 12 (detector), a transmitter 14 and a controller 16 .

The remote control 12 is provided in the bathroom 2, for example. The bathroom 2 is provided with, for example, at least two bathroom appliances such as an air conditioner 20 and a cleaning appliance 22 .

The air conditioner 20 is provided on the ceiling of the bathroom 2, for example. The air conditioner 20 has a heating function for blowing out warm air to warm the inside of the bathroom 2, a drying function for blowing out air (for example, warm air) to dry clothes hung in the bathroom 2, and ventilation in the bathroom 2. have at least one of the following: The air conditioner 20 is, for example, a bathroom ventilating, heating and drying machine. The air conditioner 20 may be, for example, a ventilation fan.

A cleaning appliance 22 is provided inside the bathroom 2 . The cleaning device 22 is, for example, a device that sprays detergent or water (hot water) on the inner wall of the bathtub. Alternatively, the cleaning device 22 may be a device that sprays water, sterilized water, or the like on the floor (washing area) of the bathroom 2 .

Note that the bathroom equipment provided in the bathroom 2 is not limited to the air conditioner 20 and the cleaning equipment 22 . The bathroom equipment may be any equipment provided in the bathroom 2 . The number of bathroom appliances provided in the bathroom 2 is not limited to two, and may be one or three or more.

The remote controller 12 has an operation unit 30 for inputting operation instructions, and a notification unit 32 for giving a predetermined notification to the bather. The operating unit 30 may be any operating member such as a push button switch or a touch sensor, for example. The notification unit 32 is, for example, a display device such as a liquid crystal display. The notification unit 32 may be, for example, a light-emitting element that provides notification with light, a speaker that provides notification with sound, or the like. The notification unit 32 may be any member capable of giving a predetermined notification to a bather or the like.

The remote control 12 is connected to the air conditioner 20 and the cleaning appliance 22, and operates these operations by inputting operation instructions input through the operation unit 30 to the air conditioner 20 and the cleaning appliance 22. FIG. In other words, the air conditioner 20 and the cleaning appliance 22 operate based on operation instructions input from the remote controller 12 .

Further, the remote controller 12 detects a predetermined operation of the bathroom equipment such as the air conditioner 20 and the cleaning equipment 22 as a specific operation immediately before the bather leaves the bathroom 2 . For example, if the air conditioner 20 is performing a heating operation, there is a high possibility that the user will stop the operation immediately before leaving the room. Also, for example, if the air conditioner 20 has a ventilation function, there is a high possibility that an operation for activating the ventilation function will be performed immediately before leaving the room. Also, for example, the cleaning device 22 is likely to be operated just before leaving the room. Therefore, the remote controller 12 detects such a predetermined operation as a specific action immediately before the bather leaves the bathroom 2 . Note that the remote control 12 may be provided for each of the air conditioner 20 and the cleaning appliance 22 . That is, a predetermined operation on bathroom equipment may be detected for each of a plurality of bathroom equipment.

The transmission unit 14 transmits a signal to a notification unit 18 (external device) provided outside the bathroom 2 . Communication between the transmission unit 14 and the notification unit 18 may be wired or wireless.

The controller 16 is connected to the remote controller 12 and the transmitter 14 . The control unit 16 controls the operation of the transmission unit 14 based on the result of detection by the remote controller 12 of a specific operation immediately before the bather leaves the bathroom 2 .

The transmission unit 14 and the control unit 16 may be provided in the bathroom 2 or may be provided in a dressing room adjacent to the bathroom 2 or the like. Also, the transmitter 14 and the controller 16 may be incorporated in the air conditioner 20 or the like, for example. In other words, the transmitter and controller of the air conditioner 20 may be used as the transmitter 14 and controller 16 of the bathroom exit detection system 10 .

The control unit 16 transmits a signal from the transmission unit 14 to the notification unit 18 in response to the remote controller 12 detecting a specific action immediately before the bather leaves the bathroom 2 . That is, the control unit 16 transmits a signal from the transmission unit 14 to the notification unit 18 when a predetermined operation on the bathroom equipment is detected.

The remote controller 12 detects a predetermined operation on at least two bathroom appliances, the air conditioner 20 and the cleaning appliance 22, as a specific action immediately before leaving the room. For example, the control unit 16 transmits a signal from the transmission unit 14 to the notification unit 18 when a predetermined operation is detected for each of at least two bathroom appliances. For example, the control unit 16 may transmit a signal from the transmission unit 14 to the notification unit 18 when a predetermined operation is detected on at least one of the at least two bathroom appliances.

The notification unit 18 is installed, for example, in a dressing room, a kitchen, or a living room. The notification unit 18 responds to the reception of the signal from the transmission unit 14 and performs a predetermined notification indicating that the bather is about to leave the bathroom 2 . As a result, it is possible to inform people in the dressing room, kitchen, living room, etc. that the bather is about to leave the bathroom 2 .

The notification unit 18 is, for example, a display device such as a liquid crystal display. The notification unit 18 may be, for example, a light-emitting element that provides notification by light, or a speaker that provides notification by sound. The notification unit 18 may be any member capable of giving a predetermined notification to a bather or the like.

The notification unit 18 may be, for example, a mobile information terminal such as a smart phone or a tablet terminal. The configuration of the notification unit 18 may be any configuration that can notify a person in a room other than the bathroom 2 that the bather is about to leave the bathroom 2 .

Further, under a predetermined condition, the control unit 16 does not transmit a signal from the transmission unit 14 to the notification unit 18 even when the remote controller 12 detects a specific action immediately before leaving the room. For example, when the signal transmission function is stopped via the operation unit 30 of the remote controller 12 , the control unit 16 prevents the transmission unit 14 from transmitting a signal to the notification unit 18 . For example, the control unit 16 may have a clock function so that the transmission unit 14 does not transmit a signal to the notification unit 18 during midnight hours. For example, a detection sensor or the like is used to detect the number of people in a house (a detached house or a room in an apartment complex such as a condominium). A signal may not be transmitted to the notification unit 18 .

As described above, the bathroom exit detection system 10 according to the present embodiment detects a specific action immediately before the bather leaves the bathroom 2, and transmits a signal to the notification unit 18 in response to this detection. . Thereby, the notification unit 18 provided outside the bathroom 2 can be operated by predicting that the bather will leave the bathroom 2 . In addition, by detecting a specific action immediately before leaving the room with the remote controller 12, it is possible to prevent the bather from forgetting to operate the bather compared to the case of providing a dedicated button for notifying the leaving of the room.

In the bathroom leaving detection system 10, the notification part 18 reports in response to the reception of the signal, thereby informing people outside the bathroom 2 that the bather is about to leave before the bather leaves the room. can be done. As a result, it is possible to prevent the occurrence of various domestic problems caused by not knowing when to leave the bathroom 2 . For example, it is possible to prevent encounters between bathers and their families in the dressing room, so that the family can go to the dressing room with peace of mind while bathing, and the family can prepare meals for the bather at the appropriate timing. can.

Further, in the bathroom exit detection system 10, the remote controller 12 detects a predetermined operation on the bathroom equipment as a specific action immediately before exiting the room. Certain bathroom appliances are often operated before leaving the room. For example, the air conditioner 20 is often stopped before leaving the room. Therefore, by detecting a predetermined operation on the bathroom equipment as a specific action immediately before leaving the room, it is possible to more accurately detect the action of the bather just before leaving the room.

In addition, in the bathroom exit detection system 10, the remote control 12 detects a predetermined operation on at least two bathroom appliances, the air conditioner 20 and the cleaning appliance 22, as a specific action immediately before leaving the room. Thereby, the movement of the bather just before leaving the room can be detected more accurately.

For example, when a signal is transmitted from the transmission unit 14 to the notification unit 18, the notification unit 32 provided in the bathroom 2 may notify the bather that the signal has been transmitted. In other words, the bather may be notified that the person outside the bathroom 2 has been notified. Thereby, the convenience of the bathroom exit detection system 10 can be further improved. For example, it is possible to notify the bather of the transmission (notification) of the signal, so that the bather can leave the bathroom 2 with peace of mind without worrying about running into a family member or the like. Note that the notification unit 32 may be provided separately from the remote controller 12 .

In the bathroom exit detection system 10, the control unit 16 does not transmit a signal from the transmission unit 14 to the notification unit 18 even when the remote controller 12 detects a specific action immediately before exiting the room under predetermined conditions. As a result, it is possible to prevent the signal from being transmitted at a timing when there is no need to inform the user that the room is about to leave, such as late at night or when there is no family, and the usability can be improved.

(Second embodiment)
FIG. 2 is a block diagram schematically showing a bathroom exit detection system according to the second embodiment.
It should be noted that the same reference numerals are given to the elements that are substantially the same in terms of function and configuration as those of the first embodiment, and detailed description thereof will be omitted.
As shown in FIG. 2, in the bathroom exit detection system 10a, the transmitter 14 transmits a signal to the air conditioner 40 (external device) provided in the dressing room 4, which is the room adjacent to the bathroom 2. As shown in FIG. The room adjacent to the bathroom 2 is not limited to the dressing room 4 and may be any room.

The air conditioner 40 adjusts the indoor temperature of the dressing room 4 . The air conditioner 40 has, for example, at least one of a heating function for blowing out warm air to warm the inside of the dressing room 4, a cooling function for blowing out cool air, and a dryer function for blowing out warm air to easily dry the hair. The air conditioner 40 may be, for example, a ventilation fan.

The control unit 16 operates the air conditioner 40 by transmitting a signal from the transmission unit 14 to the air conditioner 40 in response to the remote controller 12 detecting a specific operation immediately before leaving the room.

As described above, the bathroom exit detection system 10 a operates the air conditioner 40 of the dressing room 4 adjacent to the bathroom 2 based on the signal from the transmission unit 14 . Thereby, the air conditioning of the dressing room 4 adjacent to the bathroom 2 can be performed at an appropriate timing. Also, by operating the air conditioner 40, it is possible to notify family members that the room is about to leave.

The external device to be operated in response to detection of a specific action immediately before leaving the room is not limited to the air conditioner 40, and may be, for example, a lighting fixture provided in the dressing room 4. Further, the external device to be operated in response to the detection of the specific action immediately before leaving the room is not limited to the device provided in the adjacent room, and may be the device provided in the living room, kitchen, or the like. Any device provided in a room other than the bathroom 2 may be an external device that operates in response to detection of a specific action immediately before leaving the room.

(Third embodiment)
FIG. 3 is an explanatory diagram schematically showing a bathroom exit detection system according to the third embodiment.
As shown in FIG. 3 , the bathroom exit detection system 10 b includes a detection unit 50 . The detection unit 50 is provided on the wall surface 2 a of the bathroom 2 . The detection unit 50 detects the water splashing on the wall surface 2 a of the bathroom 2 as the movement of the bather in the bathroom 2 .

As shown in FIG. 3, the bather may clean the inside of the bathroom 2 by spraying water on the surrounding wall surface 2a and the like using a shower or the like immediately before leaving the room. The detection unit 50 detects this action of watering as a specific action immediately before the bather leaves the bathroom 2 .

For example, a radio wave sensor (microwave sensor), a voice sensor (microphone), a temperature sensor, a pressure sensor, a vibration sensor, or the like can be used as the detection unit 50 . For example, when the detection unit 50 outputs an analog signal (waveform) such as radio wave, sound, vibration, pressure, etc., the frequency at which water collides with an object is set as a band frequency, and other frequency bands are filtered (circuit or calculation processing). As a result, it is possible to improve the detection accuracy of the water sprinkled on the wall surface 2a or the like.

The wall surface 2a on which the detection unit 50 is provided may be any wall surface of the four wall surfaces that constitute the bathroom 2, for example. Further, the position where the detection unit 50 is provided is not limited to the wall surface 2a, and may be, for example, the periphery of the floor 2b of the washing area, the ceiling surface 2c, or the outer surface 2e (apron) of the bathtub 2d. The detection unit 50 detects, for example, water splashed on any one of the wall surface 2a, the peripheral edge of the floor 2b of the washing area, the ceiling surface 2c, and the outer surface 2e of the bathtub 2d. The peripheral portion of the floor 2b of the washing area is, for example, a portion of the floor surface of the floor 2b of the washing area within 15 cm from the wall surface 2a or the outer surface 2e of the bathtub 2d. The position where the detection unit 50 is provided may be any position in the bathroom where a large amount of water does not splash during normal bathing.

In addition, the detection unit 50 further detects entry of the bather into the bathroom 2 . For example, by using a radio wave sensor for the detection unit 50, water sprinkled on the wall surface 2a and the entry of the bather into the bathroom 2 can be detected by a single sensor. For example, the detection unit 50 may be configured to have a sensor that detects water and a sensor that detects entry into the room. In this case, the sensor for detecting entry into the room may be provided at a different position from the sensor for detecting water.

FIG. 4 is a graph diagram schematically showing an example of the operation of the control unit according to the third embodiment.
As shown in FIG. 4, the control unit 16 sets a predetermined threshold value Th for the detection result of the detection unit 50, and when the detection unit 50 detects water equal to or greater than the predetermined threshold value Th, It is determined that the detection unit 50 has detected a specific action.

Further, when the detection unit 50 detects a specific action immediately before leaving the room during a period from the detection of the entry into the room to the elapse of the predetermined time t1, the control unit 16 sends the transmission unit 14 to the external device (the notification unit 18 or No signal is sent to the air conditioner 40).

For example, like the signal Sa in FIG. 4, the control unit 16 does not transmit a signal from the transmission unit 14 to the external device even if the threshold value Th is exceeded before the predetermined time t1 elapses.

Also, the control unit 16 does not transmit a signal from the transmission unit 14 to the external device even when the time when the threshold value Th or more does not reach the predetermined time t2, for example, like the signal Sa in FIG.

For example, like the signal Sb in FIG. 4 , the control unit 16 sends a signal from the transmission unit 14 to the external device when the time period during which the threshold value Th becomes equal to or greater than the threshold value Th after the elapse of the predetermined time t1 is equal to or longer than the predetermined time t2. to send.

For example, when the time when the threshold value Th is exceeded does not reach the predetermined time t2, there is a high possibility that the water splashed for a moment, instead of the operation of watering for cleaning. Therefore, as described above, when the period of time when the threshold Th is exceeded is equal to or longer than the predetermined time t2, by transmitting a signal from the transmission unit 14 to the external device, erroneous detection due to water splashing or the like can be suppressed, and cleaning can be performed. It is possible to more reliably detect the operation of watering for.

It should be noted that detection of the watering operation is not limited to the case where the time for which the threshold value Th is reached is equal to or longer than the predetermined time t2. , it may be determined that the watering operation has been performed. Further, for example, the amount of detected water is obtained from the integrated value of the signal exceeding the threshold value Th, and when the amount of water exceeds a predetermined amount, it is determined that the watering operation has been performed. good too.

As described above, in the bathroom exit detection system 10b, the detection unit 50 detects the water splashed on any one of the wall surface 2a, the peripheral edge of the floor 2b, the ceiling surface 2c, and the outer surface 2e of the bathtub 2d. detected as the motion of That is, water sprinkling work for cleaning performed by a bather before leaving the room is detected by detecting water in a place where a large amount of water is not splashed during normal bathing in the bathroom 2 . Thereby, the movement of the bather just before leaving the room can be detected more accurately.

Further, in the bathroom leaving detection system 10b, for example, by setting the predetermined time t1 to about the average time from normal bathing to leaving the room, another action performed before that is detected as the specific action immediately before leaving the room. It is possible to suppress the detection as That is, it is possible to suppress erroneous detection of a specific action immediately before leaving the room.

For example, as described with regard to the first embodiment, even when detecting a predetermined operation of the bathroom equipment by the remote control 12 as a specific action immediately before the bather leaves the bathroom 2, the detection of entering the room is also performed. until the predetermined time t1 elapses, when the remote controller 12 detects a predetermined operation on the bathroom equipment, the transmission unit 14 does not transmit a signal to the external equipment (notification unit 18 or air conditioner 40). may

FIG. 5 is an explanatory diagram schematically showing a modification of the bathroom exit detection system according to the third embodiment.
As shown in FIG. 5 , the bathroom exit detection system 10 c includes a plurality of detection units 50 . Although two detection units 50 are shown in this example, the number of detection units 50 is not limited to two, and may be three or more. The plurality of detection units 50 are provided on different surfaces, for example, the wall surface 2a, the peripheral edge of the floor 2b of the washing area, the ceiling surface 2c, and the outer surface 2e of the bathtub 2d.

FIGS. 6A and 6B are graph diagrams schematically showing another example of the operation of the control unit according to the third embodiment.
As signals S1 and S2 shown in FIG. 6A , the control unit 16 detects water having a predetermined threshold value Th or more among the plurality of detection units 50, and the other detection units It is determined that the plurality of detection units 50 have detected a specific action immediately before leaving the room when the water of the predetermined threshold value Th or more is not detected by the detection units 50 .

Then, the control unit 16 determines that it is an erroneous detection when each of the plurality of detection units 50 detects water equal to or greater than a predetermined threshold value Th, like the signals S1 and S2 shown in FIG. 6B. .

As shown in FIG. 5, when the plurality of detection units 50 are provided on different surfaces, it is unlikely that the plurality of detection units 50 will simultaneously detect the water in the water sprinkling operation. Therefore, as described above, when each of the plurality of detection units 50 detects water equal to or greater than the predetermined threshold value Th, the control unit 16 determines that it is an erroneous detection due to the influence of an earthquake, for example. When only one of the plurality of detection units 50 detects water equal to or greater than a predetermined threshold value Th, it is determined that a specific action immediately before leaving the room has been detected. As a result, the influence of an external factor such as an earthquake can be suppressed, and the movement of the bather just before leaving the room can be detected more accurately.

FIG. 7 is a graph diagram schematically showing another example of the operation of the control unit according to the third embodiment.
When a plurality of detection units 50 are provided, for example, like the signals S1 and S2 shown in FIG. 7, after one of the plurality of detection units 50 detects water equal to or greater than a predetermined threshold value Th, a predetermined time t3 When another one of the plurality of detection units 50 detects water equal to or greater than the predetermined threshold value Th within this period, it may be determined that a specific action immediately before leaving the room has been detected.

In the action of watering for cleaning, there is a high possibility that multiple surfaces of the bathroom 2 are hit with water in turn. Therefore, as described above, after one of the plurality of detection units 50 detects water of a predetermined threshold value Th or more, another one of the plurality of detection units 50 detects water of a predetermined threshold value Th or more within a predetermined time t3. is detected, it is determined that a specific action just before leaving the room has been detected. Thereby, the movement of the bather just before leaving the room can be detected more accurately.

(Fourth embodiment)
FIGS. 8(a) and 8(b) are explanatory diagrams schematically showing a bathroom exit detection system according to the fourth embodiment.
As shown in FIGS. 8A and 8B, in the bathroom exit detection system 10d, the detection unit 52 is provided at the upper end (rim surface) of the bathtub 2d. The detection unit 52 detects the action of closing the bathtub 2 d with the bath lid 54 as the action of the bather in the bathroom 2 . The control unit 16 transmits a signal from the transmission unit 14 to the external device (the notification unit 18 or the air conditioner 40) in response to the detection unit 52 detecting the action of closing the bath lid 54. FIG.

In this way, the action of closing the bath lid 54 may be detected as a specific action immediately before leaving the room. In this case, for example, a radio wave sensor (microwave sensor), a photoelectric sensor, an illuminance sensor, or the like can be used for the detection unit 52 .

Even when the action of closing the bath lid 54 is detected as a specific action immediately before leaving the room, a plurality of detection units 52 may be provided and the detection may be performed according to the procedure described with reference to FIG. 6 or 7 . Thereby, the movement of the bather just before leaving the room can be detected more accurately.
