FIG. 2 is a block diagram of the audio device 20. As shown in FIG. The audio device 20 is
typically deployed entirely in the toilet 55 (FIG. 5), but at least speakers L, R (L, R) shall mean left
and right, respectively, in the reference configuration. And the operation key 22 is left in the
toilet 55, and the other elements are outside the toilet 55 (above the ceiling of the toilet, below
the floor of the toilet, and in the wall of the toilet). It is also possible to deploy in
[0015]
The control microcomputer 21 receives signals from the operation key 22 and the receiver 23.
The operation key 22 is mounted on the housing of the main body of the audio device 20 so that
various instructions for the audio device 20 can be input. The audio device 20 is provided with a
remote control (not shown) that allows the user to issue an instruction the same as the
instruction from the operation key 22 or an instruction further added to the instruction of the
operation key 22, and the user from the remote control The instruction is received by the
receiver 23 via radio waves or infrared rays, and is further sent from the receiver 23 to the
control microcomputer 21. The receiver 23 also receives user position information of the human
body proximity sensor 14 from the transmitter / receiver 13 of the toilet apparatus 10, and the
information is also sent to the control microcomputer 21.
[0016]
A DSP (Digital Signal Processor) 27 receives various instructions such as reproduction of a
predetermined music from the control microcomputer 21, and sends various information to the
control microcomputer 21. The reproduction data storage unit 30 is, for example, a removable
memory card, a built-in HDD, a built-in non-volatile memory or the like, and data related to a
plurality of music pieces is recorded. When playing back music, the DSP 27 reads out the
corresponding data from the reproduction data storage unit 30, decodes it, and outputs the
digital audio signals of the left and right channels after decoding to the DAC 31.
[0017]
The DAC 31 converts the digital audio signals of the left and right channels from the DSP 27 into
analog audio signals, and outputs the analog audio signals to the volume adjustment unit 29. The
08-05-2019
5
volume adjustment unit 29 receives the left and right volume control signals from the control
microcomputer 21, amplifies the analog audio signals of the left and right channels with gains
based on the left and right volume control signals, and outputs them to the audio signal
switching unit 34. .
[0018]
The audio signal switching unit 34 controls each output destination of the analog audio signal of
each of the left and right channels from the volume adjustment unit 29 based on the control
signal from the control microcomputer 21. The analog audio signals of the left and right
channels are respectively output to the amplifiers 36a and 36b at the first switching position of
the audio signal switching unit 34, and are respectively output to the amplifiers 36b and 36a at
the second switching position. . The amplifiers 36a and 36b amplify the audio signal from the
audio signal switching unit 34 and send it to the speakers L and R.
[0019]
Although the “reference direction” will be described in FIG. 5 later, the control microcomputer
21 detects the direction of the user 57 in the toilet 55 from the output signal of the human body
proximity sensor 14 or the seating sensor 16 (FIG. 1). In the case of the direction of the
reference, the audio signal switching unit 34 is switched to the first switching position. Also,
when the user 57 faces in the opposite direction to the reference direction, the audio signal
switching unit 34 is switched to the second switching position.
[0020]
In the example of FIG. 2, the audio signal switching unit 34 for switching the audio signal of each
of the left and right channels sent to the speakers L and R is interposed between the volume
adjustment unit 29 and the amplifiers 36a and 36b. 34 can be interposed between the DAC 31
and the volume control unit 29. However, in that case, the left and right volume control signals
sent from the control microcomputer 21 to the volume adjustment unit 29 are signals that are
left-right reversed at the time of the first switching position and the time of the second switching
position of the audio signal switching unit 34. Sent by line.
08-05-2019

[0021]
Further, the audio signal of the left and right channels sent to the speakers L and R can be
switched by the DSP 27 without the audio signal switching unit 34. The transmission of the audio
signal of each of the left and right channels from the DSP 27 to the DAC 31 uses the same signal
line in a time division manner. Therefore, when transmitting the audio signals of the right and
left channels to the speakers L and R respectively, the audio sent from the DSP 27 to the DAC 31
when transmitting the audio signals of the right and left channels to the speakers L and R,
respectively. The time slots of the signal may be assigned in reverse. Then, when the audio
signals of the left and right channels are respectively transmitted to the speakers L and R, and
when the audio signals of the right and left channels are respectively transmitted to the speakers
L and R, the volume adjustment unit 29 from the control microcomputer 21. The left and right
volume control signals to be sent to each other are sent to the left and right signal lines.
[0022]
FIG. 3 is a block diagram of the mechanical switch 15 for detecting the toilet bowl portion. The
mechanical switch 15 includes a toilet seat limit switch 51 and a lid limit switch 52. In the
example of FIG. 3, the toilet seat limit switch 51 and the lid limit switch 52 are described as being
off when the rod is projected upward, and turned on when the rod is pushed downward, but the
setting is reversed. I don't care.
[0023]
The toilet bowl 40 includes a toilet bowl body 41, a toilet seat 42, a lid 43 and a water tank 44.
For convenience of explanation, in the toilet bowl 40, the water tank 44 side is defined as the
rear, and the side opposite to the water tank 44 is defined as the front.
[0024]
The toilet body 41 is fixed to the floor of the toilet 55 on the lower surface. The toilet seat 42 is
pivotally supported at its rear end and is placed on the upper surface of the toilet body 41 (the
first and second positions from the top on the right in FIG. 3) and the front end thereof. It is
pivotable between an open position (the position illustrated third from the top on the right side
08-05-2019
7
in FIG. 3) pulled up from the position.
[0025]
The lid 43 is pivotally supported at the rear end and is placed on the upper surface of the toilet
seat 42 in the closed position (the position illustrated first from the top on the right in FIG. 3) and
the front end is pulled up from the toilet body 41 It is pivotable between the open position (the
second and third positions from the upper right of FIG. 3). Since the toilet seat 42 is disposed
below the lid 43, the lid 43 is always in the open position when the toilet seat 42 is in the open
position, and the toilet seat 42 is always in the closed position when the lid 43 is in the closed
position.
[0026]
The toilet seat 42 and the lid 43 respectively have operation pieces 47 and 48 that rotate
integrally at the rear end, and the toilet seat limit switch 51 and the lid limit switch 52 are
pressed from the operation pieces 47 and 48, respectively. And it is possible to switch on and off
according to the release of pressing.
[0027]
The toilet seat limit switch 51 is pushed downward by the operation piece 47 in the open
position of the toilet seat 42 to be in the on position, and in the closed position of the toilet seat
42, the downward push from the operation piece 47 is released and is off It becomes a position.
In the open position of the lid 43, the lid limit switch 52 is pushed downward by the operation
piece 48 to be in the on position, and in the closed position of the lid 43, the downward push
from the operation piece 48 is released and the lid 43 is turned off. It becomes a position.
[0028]
When a person uses the toilet 55 in a standing posture, the person is turned backward, and the
toilet seat 42 and the lid 43 are both in the open position (the third illustrated position from the
upper right side of FIG. 3). When a person sits on the toilet seat 42 in the toilet 55, the person is
08-05-2019
8
in the forward position, and the seat 42 and the lid 43 are in the closed position and the open
position, respectively (from the upper right of FIG. 3). Position shown in the second)). Therefore,
the direction of the person in the toilet 55 can be detected from the on / off position of the toilet
seat limit switch 51 and the lid limit switch 52.
[0029]
The human body proximity sensor 14 and the seating sensor 16 are distinguished from switches
including movable parts such as the toilet seat limit switch 51 and the lid limit switch 52, and
have a structure without a movable part. The human body proximity sensor 14 is set at one or
more predetermined positions in the toilet 55, and detects the user position in the toilet 55 and,
therefore, the user's approach to the toilet seat 42. The human body proximity sensor 14 is
distributed, for example, in the case of a light system configuration, on the ceiling, floor and wall
of the toilet 55 and at one or more predetermined portions of the toilet bowl 40, and the
reflected amount or traveling destination of emitted light The amount of light reaching the light
may be detected to detect the presence or absence of the human body portion at each space
portion in the toilet 55.
[0030]
Further, the human body proximity sensor 14 detects the user position in the toilet 55, for
example, in the height direction or in the front-rear direction. Thereby, the human body
proximity sensor 14 can also serve as the seating sensor 16. The human body proximity sensor
14 determines that the user is seated on the toilet seat 42, for example, when the user position in
the toilet 55 is low. When the user position in the toilet 55 is high, it is determined that the user
is standing in the toilet 55. Furthermore, when the user position in the toilet 55 is close to the
toilet 40 in the front-rear direction of the toilet 55, it is determined that the user is sitting on the
toilet seat 42. When the toilet 55 is separated from the toilet 40 in the front-rear direction, it is
determined that the user is standing in the toilet 55.
[0031]
The human body proximity sensor 14 can also adopt a load detection type configuration. In that
case, the human body proximity sensor 14 is embedded in a predetermined portion of the floor
in the toilet 55, and detects the presence or absence of the user at the predetermined portion
08-05-2019
9
based on the weight caused by the weight when the user steps on the predetermined portion. Do.
[0032]
The seating sensor 16 comprises, for example, a piezoelectric element. The seating sensor 16 is
mounted on the toilet seat 42 and detects seating based on the presence or absence of a load
caused by the weight of the user on the toilet seat 42. A predetermined load is applied to the
seating sensor 16 mounted on the toilet seat 42 when the user is seated on the toilet seat 42, and
no load is applied when the user is standing.
[0033]
The orientation of the user in the toilet 55 can be detected based on the output of the human
body proximity sensor 14, the mechanical sensor 15 and / or the seating sensor 16. The seating
sensor 16 may also be included within the concept of the human body proximity sensor 14 as
detecting the user's position within the toilet 55.
[0034]
When a person is absent in the toilet 55, it is desirable to deactivate the audio device 20 or
deactivate some functions in the toilet function control unit 17 in order to save power. When the
lid 43 is in the closed position (the position illustrated first from the top on the right side of FIG.
3), the toilet 55 can be presumed to be absent, so the toilet limit switch 52 is turned on / off. It is
possible to detect the presence or absence of a person in If one or more deployed human body
proximity sensors 14 can not detect the user position, it can be determined that the user is not
present in the toilet 55. Furthermore, when the user position can not be detected by the human
body proximity sensor 14 and the seating sensor 16 detects non-seating, it can be determined
that the user is not present in the toilet 55.
[0035]
When it is determined from the output of the human body proximity sensor 14, the mechanical
08-05-2019
10
sensor 15 and / or the seating sensor 16 that there is a person in the toilet 55, the audio device
20 is activated to make the audio device 20 available to the user. . When it is determined that
there is no person in the toilet 55, the audio device 20 is fully or partially stopped to save power.
[0036]
FIG. 4 shows various mounting positions of the speakers L and R in the toilet 55. Hereinafter, for
convenience of description, the front-rear direction of the toilet 55 is defined to coincide with the
above-described front-rear direction of the toilet 40. That is, the direction from the water tank 44
to the toilet bowl body 41 is defined as the forward direction of the toilet 55, and the direction
from the toilet bowl body 41 to the water tank 44 is defined as the rearward direction of the
toilet 55. The heights of the speakers L and R in each of FIGS. 4A to 4D are equal to each other.
[0037]
In FIG. 4A, the speakers L and R are attached to the left and right of the rear surface portion of
the water tank 44 rearward. In FIG. 4B, the speakers L and R are attached to the left and right
sides of the toilet body 41 respectively toward the left and right.
[0038]
In FIG. 4C, the speakers L and R are attached to the right and left on the left and right side walls
of the toilet 55, respectively. In FIG. 4D, the speakers L and R are attached to the front wall of the
toilet 55 toward the rear.
[0039]
FIG. 5 illustrates the sound emitted from the speakers L and R when the user 57 is sitting on the
toilet 40 and is standing by. In FIG. 5 and FIG. 6 described later, the left sound means the output
sound of the audio signal of the left channel, and the right sound means the output sound of the
audio signal of the right channel. Furthermore, regarding the attachment position of the speakers
L and R, FIGS. 5 (a) to 5 (d) and 6 (a) to 6 (d) correspond to FIGS. 4 (a) to 4 (d), respectively.
08-05-2019
11
[0040]
When the user 57 is sitting on the toilet bowl 40, as shown in FIGS. 5 (a) to 5 (d), the user 57 is
facing forward, which means the human body proximity sensor 14 Or, it is detected based on the
output of the mechanical switch 15 (FIG. 1). As a result, the audio signal switching unit 34 (FIG.
2) is at the first switching position, and the left and right sounds corresponding to the audio
signals of the left and right channels are output from the speakers L and R, respectively. The left
sound and the right sound at this time are aligned with the left ear 58 l and the right ear 58 r of
the user 57 who is facing forward in the toilet 55.
[0041]
FIG. 6 illustrates the sound emitted from the speakers L and R when the user 57 is using the
toilet 55 in a standing position. When the user 57 is standing in the standing posture, as shown
in FIGS. 6A to 6D, the user 57 is facing backward, which means that the human body proximity
sensor 14 or the mechanical switch 15 is used. It is detected based on the output of (FIG. 1). As a
result, the audio signal switching unit 34 (FIG. 2) is at the second switching position, and the
right and left sounds corresponding to the audio signals of the right and left channels are output
from the speakers L and R, respectively. The left sound and the right sound at this time are
aligned with the left ear 58 l and the right ear 58 r of the user 57 facing backward in the toilet
55.
[0042]
FIG. 7 is a block diagram of the toilet system 75. As shown in FIG. The toilet system 75 includes a
toilet apparatus 76 and a toilet audio apparatus 77. The above-described toilet apparatus 10 and
audio apparatus 20 are specific examples of the toilet apparatus 76 and the toilet audio
apparatus 77, respectively.
[0043]
The toilet apparatus 76 has a seating detection means 80 and a human body detection means 81.
08-05-2019
12
The seating detection means 80 detects that the user is seated on the toilet seat. The human body
detection means 81 detects the presence or absence of a human body in the toilet. The
aforementioned human body proximity sensor 14 and seating sensor 16 (FIG. 1) are specific
examples of the seating detection means 80 and the human body detection means 81,
respectively.
[0044]
The toilet audio apparatus 77 has an audio signal generating means 84 and speakers 85a and
85b. Audio signal generation means 84 generates audio signals of the left and right channels. At
least two speakers 85a and 85b are respectively disposed on one side and the other side in the
left-right direction in the toilet, are supplied with audio signals of different channels, and output
audio related to the supplied audio signals.
[0045]
The toilet audio apparatus 77 further includes an orientation detection unit 88 and an audio
signal switching unit 89. The direction detection means 88 detects whether the user is facing the
reference direction or the opposite direction in the toilet based on the outputs of the seating
detection means 80 and the human body detection means 81. The audio signal switching unit 89
switches the channel of the audio signal sent to each of the speakers 85 a and 85 b based on the
output of the direction detection unit 88.
[0046]
The reference direction and the opposite direction are, for example, the forward and backward
directions described above in FIG. In that case, the speakers 85a and 85b disposed on one side
and the other side correspond to the speakers L and R, respectively. The orientation detection
unit 88 may detect the orientation of the user in the toilet based on only one output of the
seating detection unit 80 or the human body detection unit 81, or based on the outputs of both
the seating detection unit 80 and the human body detection unit 81. The orientation of the user
in the bathroom may be detected.
[0047]
08-05-2019
13
In the toilet system 75 that detects the direction of the user based only on the output of the
seating detection means 80, if the seating detection means 80 detects that the user is not seated
on the toilet seat, even if the user is not in the toilet Assuming that the user is in the standing
posture, audios of left and right channels corresponding to the left and right with respect to the
user orientation in the standing posture flow from the speakers 85a and 85b, but if the user is
not in the toilet, the speaker 85a, If the left and right channels of the audio flowing from 85b do
not correspond to the left and right with respect to the user orientation, there is no problem with
that. Further, as described later, when the operation of the toilet audio device 77 is stopped while
the user is not present in the toilet, there is no problem regarding the channel switching in the
audio signal switching unit 89. The same applies to the toilet system 75 that detects the direction
of the user based only on the output of the human body detection means 81.
[0048]
While the seating detection means 80 detects the seating and non-seating of the user on the
toilet seat, the human body detection means 81 detects whether or not the distance from the
user to the toilet is within the criteria based on the current user position. It will be done. That is,
if the user distance is within the reference, it can be determined that the user is seated, and if
outside the reference, it can be determined that the user is standing up.
[0049]
Thus, the toilet system 75 can stream audio from the left and right channels matched with the
user's orientation from the speakers 85a and 85b regardless of the orientation of the user in the
toilet.
[0050]
The toilet audio apparatus 77 can further include a deactivating means 93.
The presence or absence of the user in the toilet is detected based on the output of the human
body detection means 81. The operation stop unit 93 stops the operation of the toilet audio
device 77 when there is no user in the toilet. Moreover, the method of the operation stop may be
stopped after a predetermined time (for example, 20 minutes) since the seating detection means
08-05-2019
14
80 detects the presence of the user in the toilet. By doing so, in the case where the human body
detection means 80 is broken or the like, it can be reliably stopped after a predetermined time.
[0051]
The operation stop of the toilet audio device 77 by the operation stop means 93 includes not
only a full operation stop but also a partial operation stop within the concept. The partial
deactivation of the toilet audio device 77 means, for example, deactivating at least one or more of
the audio signal generating means 84, the speakers 85a and 85b, the audio signal switching
means 89, and the direction detecting means 88. Do. The presence / absence detection means 92
and the operation stop means 93 are not normally deactivated in preparation for the next
activation of the toilet audio device 77. If the operation of elements upstream of the speakers
85a and 85b with respect to the flow of the audio signal is stopped, the speakers 85a and 85b
generally do not output audio even in the activated state. By stopping the operation of the toilet
audio device 77 by the operation stop unit 93, the power consumption of the toilet audio device
77 can be suppressed.
[0052]
Typically, the resumption of the operation of the toilet audio device 77 by the operation stop
means 93 is performed after the presence / absence detection means 92 detects the user's entry
into the toilet. The presence or absence of the user can be detected based on the lighting state of
the electric light of the toilet or the operating state of the ventilation fan of the toilet instead of
the output of the seating detection means 80 or the human body detection means 81.
[0053]
Preferably, the audio signal switching unit 89 continues switching of the channel of the audio
signal within a predetermined time after the seating detection unit 80 detects that the user is not
seated. The predetermined time is set, for example, as an equivalent time which it takes from
when the user gets up from the toilet seat to when it leaves the toilet.
