Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bather watching system, and more particularly to a bather watching system which allows a bather to be watched more finely and a person other than the subject not feel uncomfortable.

[0002]

2. Description of the Related Art Conventionally, there is a system for watching a bather and detecting an abnormality in the bather, for example, Japanese Patent Application No. 10-
No. 303436 and Japanese Patent Application No. 2000-195338.

As is well known, this bather watching system includes a main body unit installed in a living room and the like.
It is composed of a bathroom unit installed in the bathroom and a bathroom entrance / exit unit installed at the entrance / exit of the bathroom.

These units cooperate with each other to watch over bathers, particularly the elderly, and prevent accidents in the bathroom.

[0005]

[Problems to be Solved by the Invention]

[0006] However, the above-mentioned conventional bather watching system has the following problems.

(1) In general, if an elderly person is soaked in a bathtub having an excessively high temperature for a long time, he or she may be hot or dizzy and may be unable to move.

However, since the conventional bather watching system does not adopt a watching system in consideration of the relationship between the hot water temperature and time, the elderly person inadvertently soaked in a hot water bath for a long time as described above. It may fall into such a situation.

(2) Conventionally, the bather watching system issues a pre-bell when the bather does not move for a predetermined time, for example, 2 minutes or more, and prompts the movement. Emit a bell.

However, it is unknown to the bather how many minutes the pre-bell will start, that is, the remaining time before the start of the pre-bell.

Therefore, suddenly, "Is it okay?"
Such a pre-bell may be very surprising, and you may not be able to take a bath without worry if you do not know the remaining time until the start of the pre-bell.

Since the pre-bell is output by voice, it is difficult for a hearing-impaired person to use the conventional bather watching system.

In this case, it is conceivable to make the voice loud, but for example, outputting a loud voice at night is annoying to the neighbors and is not preferable in the environment.

(3) In the conventional bather watching system, as described above, when the bather does not move for 2 minutes or more,
The advance bell promotes the movement of the bather.

Therefore, even if the pre-bell is issued, the family member outside the bathroom cannot talk with the bather in the bathroom, and therefore the actual appearance of the bather is not clear.

(4) The users of the bather watching system are
Generally, the person is an elderly person, and the watching time is determined to be, for example, 2 minutes.

However, even when another family member takes a bath, it is extremely annoying that the pre-bell is issued every two minutes and the person is asked "Is it okay?".

In addition, when a visitor such as a relative takes a bath, he or she may not know anything about the bather watching system, and similarly, the pre-bell is uncomfortable and unfamiliar. .

Further, in this bather watching system, conventionally, when two people take a bath and one goes out, the remaining bathers are confirmed by voice.

That is, when two people are taking a bath and one is out, the watching operation ends as it is.

Therefore, in order to continue watching the remaining person, the voice message "Please touch the sensor when there is a person inside" is output and confirmed.

However, when the washing machine is installed in the bathroom or when the hot water of the bathtub is pumped out to the outside washing machine, the bathroom may come and go frequently. It is extremely annoying that the confirmation by voice is made each time.

(5) The bather watching system has hitherto been premised on the presence of a cohabitant such as a wife or a child in order to watch over the elderly person who is the subject.

However, the cohabitant is not always near the elderly person and may go out for shopping or the like.

In this way, when the cohabitant was absent, an unusual situation occurred in the young and the elderly, and the main bell was emitted.
If the cohabitant cannot be contacted, the bather watching system will not work effectively for the original function of protecting the elderly.

(6) Conventionally, the bather watching system, when starting watching, sounds a music box and plays a certain music in the bathroom to inform the bather that the device is operating and watching. , Gives a sense of security.

However, this music is reproduced by the music box, is a predetermined music, and is not always the bather's favorite.

Therefore, the conventional bather watching system cannot be said to be suitable for seeking further relaxation and comfort while taking a bath.

An object of the present invention is to provide a bather watching system in which a bather can be more closely watched and a person other than the subject does not feel uncomfortable.

[0030]

[Means for Solving the Problems] In order to solve the above problems, the present invention measures the hot water temperature when a bather enters a hot water bath and responds to the measured hot water temperature. When the bather does not leave the bathtub even after the set time has elapsed, an alarm is issued (hot water temperature alarm system 8 in FIGS. 2 to 4), and as described in claim 2, Set the time from the detection of the last movement of the bather to the start of the pre-bell, and display the remaining time of the set time by reading the minutes and seconds (pre-bell display / flashing method 9 in FIGS. 5 to 7), As described in claim 3, when the pre-bell is started, the flash light blinks in synchronization with the pre-bell (same method), and the intercom master unit is installed in the bathroom as described in claim 5. , Install intercom slaves outside the bathroom, and A telephone is activated to enable communication inside and outside the bathroom (intercom interlocking system 10 in FIG. 8), and when a person other than the target person uses it, a predetermined operation mode is set. , The monitoring condition is relaxed according to the set operation mode (see FIG.
As described in the operation mode method 11) of FIG. 12 and claim 10, a telephone number corresponding to a predetermined telephone is registered in advance, and at the time of the main bell, an emergency automatic call is made to the telephone of the registered telephone number (Fig. 13 to 14 of the telephone connection system 12), as described in claim 12, it has a built-in ringtone playback function, pre-registers predetermined performance data, and plays the ringtone based on the performance data when bathing. The function is activated to play the music corresponding to the performance data (Fig. 15 to Fig. 1).
6 ringtone playback system 13).

According to the above-mentioned configuration of the present invention, the hot water temperature alarm system 8 (FIGS. 2 to 4) enables the user to take a bath only for a time period corresponding to the hot water temperature, thus preventing accidents of the elderly in the bathroom. Pre-bell display / blinking method 9 (Figs. 5 to 7)
By doing so, the remaining time until the start of the pre-bell is counted down and displayed, which gives the bather a sense of security, and when the pre-bell is started, the pre-bell can be known by blinking the flash light, so it can be used by people with hearing loss. With the intercom interlocking system 10 (Fig. 8), the cohabitant can hear the sound in the bathroom, so that the actual state of the bather can be known, and the operation mode system 11 (Figs. 9 to 9). 12)
Since it is possible to set a family mode different from the normal mode, people other than the target person can use the bather watching system without feeling any discomfort, and the telephone connection method 12 (Fig. 13-
According to FIG. 14), even if the cohabitant is absent, it is possible to notify the cohabitant who is not present of the abnormal situation, so that the bather watching system can be effectively used, and the ringtone reproduction method 1
3 (FIGS. 15 to 16) allows you to play your favorite music, so you can further relax while taking a bath.

Therefore, according to the present invention, it is possible to provide a bather watching system in which a bather can be more closely watched and a person other than the subject does not feel uncomfortable.

[0033]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the accompanying drawings by way of embodiments. FIG. 1 is an overall view showing the configuration of the present invention. The illustrated bather watching system includes a hot water temperature alarm system 8 attached to a bathroom unit 2 and a bathroom entrance / exit unit 3, a pre-bell display / blinking system 9, It is composed of an intercom interlocking system 10, an operation mode system 11, a telephone connection system 12, and a ringtone reproduction system 13.

The main body unit 1 shown in the figure is installed, for example, in a living room of a house 4 in which an elderly person lives, the indoor unit 2 is installed on a wall of a bathroom, and the bathroom entrance / exit unit 3 is installed above a bathroom door or the like. The above-mentioned methods operate in cooperation with these units.

In this case, in order to simplify the description, the control unit of each system (for example, FIG. 2) is also the control unit of the in-bathroom unit 2, and both are common (however, For intercom interlocking system 10 (Fig. 8),
A commercially available intercom is used, and the intercom master unit 10A installed in the bathroom is connected to the bathroom unit 2). However, the present invention is not limited to this, and the control unit of each system may be the control unit of the bathroom entrance / exit unit 3 or may be provided independently.

Hereinafter, the hot water temperature alarm system 8 to the ringtone reproduction system 13 will be described in detail.

(1) Hot water alarm system 8

(1) -Configuration. The hot water alarm system 8 gives an alarm to the bather if the bather does not come out of the bath even after the time determined for each hot water has passed.

As shown in FIG. 2, this hot water temperature alarm system 8 includes a control unit 8A, a hot water temperature measuring unit 8B, a hot water bath entrance / exit detection unit 8C, a timer 8D, a storage unit 8E, and a voice synthesis unit 8.
F and a speaker 8G.

Of these, the hot water temperature measuring section 8B is composed of a thermometer suspended in a hot water bath and measures the temperature of hot water.

The bathtub entrance / exit detector 8C is composed of a water level sensor or the like suspended in the bathtub, and detects whether the bather enters or exits the bathtub.

When the timer 8D is set, the time set when it is set, that is, the timer value is relatively long (for example, 20 to 30).
It is a timer and measures the time determined for each hot water temperature.

In this case, the relationship between the hot water temperature and the timer value is shown in FIG. 3. For example, when the hot water temperature is 43 ° C.
When the timer value is 5 minutes and the hot water temperature is 38 ° C, the timer value is 20 minutes.

The relationship between the hot water temperature and the timer value is stored in the storage unit 8E in advance.

As a result, the hot water temperature measuring section 8B
For example, when the hot water temperature is measured to be 38 ° C. (FIG. 3) (step 102 in FIG. 4), the timer 8D is set based on the relationship between the hot water temperature and the timer value stored in the storage unit 8E.
Is set (step 103 in FIG. 4) and the timer value is set to 20 minutes.

Then, while the bather is still in the bathtub (NO in step 104 of FIG. 4), the timer 8D has timed out (YES in step 105 of FIG. 4) and the set 20 minutes have passed. In this case, the speaker 8G gives an alarm such as "Please leave the bathtub" (Fig. 4).
Step 106).

As described above, the voice synthesizing unit 8F determines that the bather does not leave the bathtub even after the lapse of the time determined for each bath temperature (FIG. 3) (YE in step 105 in FIG. 4).
S), the alarm sound for the bather is voice-synthesized, for example, the speech sound such as "please get out of the bathtub" is synthesized, and the speech sound is output from the speaker 8G.

(1) -Operation. The operation of the hot water alarm system 8 according to the present invention having the above configuration will be described below with reference to FIG.

A. Operation until timer 8D is set.

In step 101 of FIG. 4, it is judged whether or not it has been detected that the bathtub has been entered. If it is not detected (NO), the same operation is repeated, and if it is detected (Y
ES), the hot water temperature is measured in step 102, and the timer 8D is set in step 103.

That is, the control unit 8A (FIG. 2) waits until it receives an incoming signal from the bathtub entrance / exit detection unit 8C, and when the incoming signal is received, it is considered that the bather has entered the bathtub. ,
This time, the hot water temperature measuring unit 8B is controlled to measure the hot water temperature.

As a result of the measurement, for example, when the temperature of the hot water, that is, the hot water temperature (FIG. 3) is 43 ° C., the control unit 8A
Compares the relationship between the hot water temperature stored in the storage unit 8E and the timer value, sets the timer 8D, and sets the timer value to 5 minutes.

B. Operation after setting timer 8D.

Then, in step 104 of FIG.
It is determined whether or not the exit from the bathtub is detected, and when it is detected (YES), in step 107, the timer 8D
, And the audio output is stopped in step 108.

That is, when the control unit 8A receives the outgoing signal from the bathtub entrance / exit detection unit 8C (FIG. 2), immediately after the timer 8D is set (step 103 in FIG. 4), the bather takes a bathtub. It is determined that the timer 8D does not need to measure the elapsed time, the operation is stopped, and the sound output from the speaker 8G is also stopped. .

However, in step 104 of FIG.
If it is not detected that the bathtub has exited (NO), in step 105, it is determined whether or not the timer 8D has timed out. If not, (NO),
Returning to step 104, the same operation is repeated.

Then, when the time is up (YE
S), in step 106, "please leave the bathtub" is output by voice synthesis, and the process returns to step 104 to repeat the same operation.

That is, the control unit 8A (FIG. 2) does not receive the output signal from the bathtub entrance / exit detection unit 8C, the timer 8
When D is timed up, and when the time is up, that is, when 5 minutes corresponding to the hot water temperature of 43 ° C. (FIG. 3) has elapsed, the voice synthesizing unit 8F is controlled to perform the above-mentioned operation. "Please leave the bathtub" is synthesized into a voice and output from the speaker 8G.

As for the alarm generated by the voice output from the speaker 8G, the control unit 8A causes the bathtub entrance / exit detection unit 8C.
Until the bather detects that the bather has exited the bathtub (YES in step 104 in FIG. 4).

In this way, if the hot water temperature is high (Fig. 3), the bath time can be shortened so that the bath time can be changed according to the hot water temperature. We are preventing it.

(2) Pre-bell display / blinking method 9

(2) -Configuration. In the pre-bell display / blinking method 9, the remaining time until the pre-bell is started is displayed by reading minutes and seconds, and when the pre-bell is started, the flashlight 9H2 is blinked.

As shown in FIG. 5, the pre-bill display / blinking system 9 includes a control unit 9A, a transmission / reception unit 9B, and a two-minute timer 9 as shown in FIG.
C, cancel switch 9D, amplifier 9E, microphone 9F
And a light emitting circuit 9G and a display portion 9H.

In the pre-bell display / blinking method 9, the movement of the bather is detected by an internal sensor 9J installed outside (for example, a wall of the bathroom), and the detection signal A at that time is transmitted via the transmitting / receiving section 9B. It shall be received wirelessly.

Further, in this case, the pre-bell signal B is sent from the main body unit 1 (FIG. 1) and is wirelessly received via the transmitter / receiver 9B, and is also wirelessly received by the bathroom entrance / exit unit 3 and the bathroom entrance / exit From the speaker 3B2 of the unit 3, it is assumed that the pre-bell is also output as a voice such as "Is it okay?". Alternatively, the pre-bell signal B may be input from the main unit 1 (FIG. 1) by wire.

The 2-minute timer 9C is set when the inner sensor 9J detects the movement of the bather (YES in step 201 in FIG. 7 or YES in step 208) (step 202 in FIG. 7), and the set time is set. Is 2 minutes until the start of the pre-bell, and the minutes and seconds are read by counting down the remaining time of 2 minutes (step 203 in FIG. 7).

The remaining time after the minute / second has been read by the 2-minute timer 9C appears in the timer value at that time, so the timer value is displayed on the screen 9H1 (FIG. 5) of the display unit 9H (FIG. 6, FIG. 6). Step 204 of 7.).

When the cancel switch 9D is pressed by the bather, the abnormality notification (the state in which the inner sensor 9J does not detect the movement of the bather for 2 minutes) causes the main unit 1 (FIG. 1).
This is a switch for canceling the transmission to.

Therefore, even if the inner sensor 9J does not detect the movement of the bather (NO in step 201 in FIG. 7 or NO in step 208), the cancel switch 9D is pressed (in FIG. 7). If YES in step 207 or YES in step 209), the 2-minute timer 9C is set (step 202 in FIG. 7).

Further, the microphone 9F (FIG. 5) is attached to the speaker 3B2 of the bathroom entrance / exit unit 3, so that the pre-bell output from the speaker 3B2 is input to the microphone 9F as sound, and the amplifier 9E outputs the pre-bell. After amplifying the pre-bell, the light emitting circuit 9G is turned on through the control unit 9A to blink the flashlight 9H2.

In this case, the control unit 9A determines that the voice signal input from the microphone 9F has a predetermined sound pressure level and frequency as a pre-bell, or the voice signal is "OK" based on the voice recognition function. Only when it is judged that it is a pre-bell, the light emitting circuit 9G is turned on so as not to react to other sounds such as a music box sound emitted from the unit 2 in the bathroom.

Alternatively, the light emitting circuit 9G is connected to the current sensor built in the speaker 3B2, and when the current flows in the current sensor according to the pre-bell, the light emitting circuit 9G is turned on, and the speaker 3B2 is Transmitter / receiver 9B regardless of
The light emitting circuit 9G may be turned on based on the pre-bell signal B directly received from the main unit 1 (FIG. 1) via the or the pre-bell signal B directly input from the main unit 1 by wire.

(2) -Operation. The operation of the pre-bell display / blinking method 9 according to the present invention having the above configuration will be described below with reference to FIG.

A. Operation until the start of the pre-bell.

In step 201 of FIG. 7, it is judged whether or not the detection signal A is received from the inner sensor 9J, and if it is received (YES), the process proceeds to step 202.

If it is not received (NO), it is determined in step 207 whether or not the cancel switch 9D is pressed. If it is pressed (YES), step 2
02, if not pressed (NO), step 2
Return to 01 and repeat the same operation.

That is, the control unit 9A (FIG. 5) detects the movement of the bather by receiving the detection signal A from the external internal sensor 9J via the transmission / reception unit 9B, or the cancel switch 9D is activated. It waits until it is pressed, and if any of these operations occurs, it proceeds to step 202 and sets the 2-minute timer 9C.

In this case, the time set by the 2-minute timer 9C is the time until the start of the pre-bell, that is, 2 minutes, as described above.

Then, in step 203 of FIG. 7,
The countdown is performed, and in step 204, the timer value is displayed.

That is, the 2-minute timer 9C sets the remaining time of 1 minute 59 seconds after setting 2 minutes which is the time until the start of the pre-bell.
Minute / second reading is performed by counting down 1 minute 58 seconds ... And the timer value at that time is displayed on the screen 9H1 of the display section 9H via the control section 9A (FIG. 6). .

Then, in step 205 of FIG. 7,
If the timer value is 0 (YES), that is, if the remaining time is exhausted, the pre-bell is started, so the process proceeds to step 206 of the next stage.

However, in step 205 of FIG.
If the timer value is not 0 (NO), that is, if there is still the remaining time, the routine proceeds to step 208, and the inner sensor 9J
It is determined whether or not the detection signal A from is received (YES), or even if it is not received (NO), in step 209, if the cancel switch 9D is pressed (YES). , In step 202, the 2-minute timer 9C is set again.

In this case, the inner sensor 9J again detects the movement of the bather, or the bather rejects the detection by the inner sensor 9J, so that the 2-minute timer 9C is reset (see FIG. 7). Step 202), the time of 2 minutes until the start of the pre-bell is set again, and the remaining time is counted down again, so that the minutes / seconds are read and the timer value is displayed (steps 203 → 204 in FIG. 7).

In step 205 of FIG. 7,
If the timer value is not 0 (NO) and there is remaining time, the process proceeds to step 208, but the detection signal A from the inner sensor 9J is not received (NO), and the cancel switch 9D is also pressed in step 209. If not (NO),
Since the countdown is in progress, minute / second reading and display are continued (step 203 → 204 in FIG. 7).

B. Operation after the start of the pre-bell. If the timer value is 0 in step 205 of FIG. 7 (YES), the pre-bell is started when the remaining time is exhausted, and the flash light 9H2 is blinked in step 206.

That is, when the remaining time counted down by the 2-minute timer 9C (FIG. 5) disappears and 2 minutes elapse,
The main unit 1 (Fig. 1), the inner sensor 9J (Fig. 2) 2
Preliminary bell signal B
And the pre-bell signal B is received by the bathroom entrance / outlet unit 3 while being received via the transmitter / receiver 9B.

Then, the pre-bell as the sound output from the speaker 8G of the bathroom entrance / exit unit 3 is input to the microphone 9F and amplified by the amplifier 9E, and the control unit 9A causes the predetermined sound pressure, etc., as described above. On condition that
The light emitting circuit 9G is turned on to flash the flashlight 9H2.

Alternatively, when the light emitting circuit 9G is connected to a current sensor built in the speaker 8G, when a current flows in the current sensor according to the pre-bell, the light emitting circuit 9G
By turning on G, the flashlight 9H2 blinks.

Further, as described above, regardless of the speaker 3B2, the pre-bell signal B received directly from the main unit 1 (FIG. 1) via the receiving section 9B and the pre-bell signal directly input from the main unit 1 by wire. By turning on the light emitting circuit 9G based on the signal B, the flashlight 9H2
Blink.

The flashlight 9H2 is turned off when the pre-bell signal B is no longer transmitted from the main unit 1 (FIG. 1).

By the operations of A and B, by counting down the remaining time until the start of pre-belling,
Since it is displayed in seconds, it gives the bather a sense of security, and the start of the pre-bell is indicated by the flashing flash light.
It also enables people with hearing loss.

(3) Regarding intercom interlocking system 10.

(3) -Configuration. The intercom interlocking system 10 activates an intercom during a pre-bell and a main bell so that a call can be made inside or outside the bathroom.

As shown in FIG. 8, this intercom interlocking system 10 uses a commercially available intercom to
Place the intercom base unit 10A outside the bathroom (for example, in the kitchen),
Intercom slave unit 10B is installed respectively.

Thus, the intercom slave unit 1 on the kitchen side
Even if the call switch 10B3 of 0B is pressed, if the call switch 10A4 on the side of the intercom base unit 10A is not responded to, the call is impossible and the privacy of the bather is protected.

However, as will be described later, for example, at the time of pre-bell, the call switch 10A4 on the intercom master unit 10A side.
When is automatically turned on, the intercom is activated and you can talk inside or outside the bathroom, so you can see the actual situation of the bather.

The intercom base unit 10A has the control unit 1
0A1, a speaker 10A2, a microphone 10A3, and a call switch 10A4, which are connected to, for example, the unit 2 in the bathroom.

The intercom slave unit 10B has a speaker 10B1, a microphone 10B2, and a call switch 10B3.
And is installed outside the bathroom, for example, in the kitchen as described above.

With this configuration, when the bathroom unit 2 receives, for example, the pre-bell signal B from the main unit 1, the bathroom unit 2 sends the control signal S to the intercom master unit 10.
A to the call switch 10 via the control unit 10A1.
A4 is automatically turned on and the intercom is activated.

Therefore, if the person living together with the bather turns on the call switch 10B3 of the intercom slave 10B,
You can talk in and out of the bathroom.

(3) -Operation. Hereinafter, the operation of the intercom interlocking system 10 according to the present invention having the above configuration will be described.

For example, the sensor 2E in the bathroom unit 2
However, if the movement of the bather is not detected for 2 minutes, the main unit 1 considers that there is an abnormality in the bather and pre-bell signal B.
Is transmitted to the unit 2 in the bathroom, and a voice such as "Is it okay?" Is emitted.

At this time, as described above, the bathroom unit 2 transmits the control signal S to the intercom master unit 10A, the call switch 10A4 is automatically turned on, and the intercom is activated.

At the same time, the sound of the pre-bell such as "Is it okay?" Is heard from the main unit 1 side as well, so the cohabitant knows that the intercom has been activated and calls the intercom slave 10B call switch. By turning on 10B3, you can talk inside or outside the bathroom.

As a result, the cohabitant can hear the sound in the bathroom and know the state of the bather.

On the other hand, even with the pre-bell, the inner sensor 2E
If 2 minutes have passed without detecting the bather's movement,
A main bell signal C is transmitted from the main body unit 1 side, and a sound such as "an abnormal situation has occurred" is emitted.

In this case as well, as in the case of the pre-bell, the bathroom unit 2 transmits the control signal S to the intercom master unit 10A, the call switch 10A4 is automatically turned on, and the intercom is activated.

At the same time, the voice of this bell saying "an abnormal situation has occurred" is heard from the main unit 1 side as well, so that the cohabitant knows that the intercom is activated and the intercom slave 10B. Call switch 1
You can talk inside or outside the bathroom by turning on 0B3.

(4) Operation mode method 11

(4) -Configuration. The operation mode method 11, when used by a person other than the target person, sets a predetermined operation mode and, depending on the set operation mode, extends the normal watching time, relaxes the watching condition, etc. I do.

As shown in FIG. 9, the operation mode system 11 includes a control section 11A, a family mode button 11B, a washing mode button 11C, an inner sensor 11D, a 2-minute timer 11E, and a 30-minute timer 11F. , Washing mode timer 11G, external detection timer 11H, pre-bell timer 11J
And a speaker 11K, and further an entrance / exit switch 3X provided in the bathroom entrance / exit unit 3.

Of these, by depressing the family mode button 11B (YES in step 301 of FIG. 10), the full-auto mode of the family modes is set (step 308).

When the family mode (full auto mode) is set, the watching time is extended, for example, from the conventional 2 minutes to 30 minutes (YES in step 303, step 309), and the watching by the extended time is performed. When is finished (step 306), the family mode is canceled (step 307).

The entrance / exit switch 3X turns it on.
By doing (YES in step 401 of FIG. 11),
The semi-auto mode of the family mode is set.

When this semi-auto mode is set, watching is started (step 402 in FIG. 11), and the entrance / exit switch 3X is turned off (step 4).
If YES in step 03 or YES in step 409), the watching ends.

That is, the full-auto mode of the family mode extends the watching time, whereas the semi-auto mode determines whether or not there is watching.

When the entrance / exit switch 3X is provided, the exit sensor 3E is unnecessary and does not work.

The laundry mode button 11C is pushed down (YES in step 501 of FIG. 12),
The washing mode timer 11G, which will be described later, is set (step 509), whereby the washing mode is set.

When this washing mode is set, the voice recognition time, that is, the voice recognition time such as "Please touch the sensor when there is a person inside", as will be described later, is set to the conventional voice recognition time of, for example, 15. If the time is extended from 20 seconds to 20 minutes (YES in step 507) and the user enters or leaves the bathroom during that 20 minutes, no voice recognition is performed.

That is, the washing mode extends the voice recognition time.

The washing mode timer 11G (FIG. 9) is set (step 509) when the washing mode button 11C is pushed down (YES in step 501 in FIG. 12), and the set time is, for example, as described above. 20 minutes.

Since the washing mode timer 11G is provided, as described above, the voice recognition time can be reduced to 15 times that of the conventional one.
It has been extended from 20 seconds to 20 minutes.

(4) -Operation. Hereinafter, the operation mode system 1 according to the present invention having the above configuration
The operation of No. 1 will be described with reference to FIGS.

A. Operation in family mode (full auto mode).

The operation in this case is the operation in the family mode (full auto mode), which is added to the operation in the normal mode, shown in FIG. 10 and surrounded by broken lines (α and β).

A-Operation until setting of 1.2-minute timer 11E or 30-minute timer 11F.

In step 301 of FIG. 10, it is determined whether or not the family mode button 11B has been pressed. If it has been pressed (YES), the family mode is set in step 308, and then the process proceeds to step 302. If it is not pushed down (NO), the process directly proceeds to step 302, and in step 302, the internal sensor 11
It is determined whether D has detected a person.

That is, the control unit 11A (FIG. 9) considers that the family mode is set when the family mode button 11B is pushed down, and at that time, for example, a mode setting area of a memory (not shown). "1" is stored in.

The fact that the family mode has been set serves as a criterion for the determination (step 303 in FIG. 10) described later.

After that, in step 302 of FIG. 10, it is judged whether or not the inner sensor 11D has detected the movement of a person, and if not detected (NO), the process returns to step 301 and the same operation is repeated and detected. In case (YE
S), in step 303, it is determined whether or not the family mode is set, and if it is the family mode (YES), step 30
In step 9, the 30-minute timer 11F is set, and when the family mode is not set (NO), in step 304,
The two-minute timer 11E is set, and the process proceeds to step 305.

That is, the control unit 11A (FIG. 9), when detecting the movement of a person through the internal sensor 11D, considers that the user has taken a bath, and whether or not it is the family mode this time. Then, as described above, “1” is stored in the memory (not shown).
Is stored, it is determined to be the family mode, and otherwise, it is determined to be the normal mode.

Then, in the normal mode, the 2-minute timer 11E is set to set the watching time to 2 minutes as in the conventional case. In the family mode, the 30-minute timer 11F is set to set the watching time to 30 minutes. Extend to minutes.

A-2.2 Operation after setting the 2-minute timer 11E or the 30-minute timer 11F.

In step 305 of FIG. 10, it is judged whether or not the exit sensor 3E has detected the movement of a person, and when it is detected (YES), in step 306, 30
The minute timer 11F is stopped, and in step 307,
Cancel the family mode.

That is, the control unit 11A (FIG. 9), when detecting the movement of a person through the exit sensor 3E, judges that the user who once took a bath leaves the bathroom, and ends watching. , The set 2 minutes or 30 minutes timer (Fig. 1
Step 304 or 309 of 0) is stopped, and if "1" is stored in the memory (not shown), the "1" is erased to cancel the family mode.

Further, in step 305 of FIG. 10, it is judged whether or not the exit sensor 3E has detected the movement of the person, and if it is not detected (NO), the operation of step 310 and thereafter is the same as the conventional one. Step 311 described later
The only difference is whether the timer that is the target of the determination is 2 minutes timer 11E or 30 minutes timer 11F.

In other words, whether the watching time is 2 minutes as before,
It is an extended 30 minutes difference depending on the family mode.

The following description will be made assuming that the family mode is set (step 308 in FIG. 10) and the 30-minute timer 11F is set (step 309). That is, it is assumed that a person other than the target person, for example, a visitor, uses it.

In step 310 of FIG. 10, the inner sensor 11D
Judges whether or not the human movement is detected, and if it is detected (YES), the process returns to step 303 to set the 30-minute timer 11F again, and if not detected (N
O), 30 minutes timer 11F time up? If the time is not up (NO), the process returns to step 305 to repeat the same operation. If the time is up (YES), a pre-bell is output in step 312.

That is, the visitor first hears a pre-bell such as "Are you okay?" After 30 minutes have passed since entering the bath (YES in step 302).

However, it is usually unthinkable that the inner sensor 11D will not be blocked for 30 minutes after taking a bath.

Therefore, this visitor also normally shuts off the inner sensor 11D once during 30 minutes, and the above step 310 YES → step 303 → step 309 → step 3
The operation of 05 is performed, and the loop operation of returning to step 310 is performed. In effect, the bather watching system does not seem to be working for the visitor, and there is no discomfort.

Thereafter, the pre-bell timer 11J is set in step 313 of FIG. 10, and the inner sensor 11 is set in step 314.
When D detects the movement of a person (YES), it is determined that there is no abnormality in the visitor, the pre-bell is stopped in step 318, the pre-bell timer 11J is also stopped in step 319, and the 30-minute timer 11F again. To set, return to step 303.

If the inner sensor 11D does not detect the movement of the person in step 314 (NO), but the exit sensor 3E detects the movement of the person in step 315 (YE
S): The pre-bell is stopped in step 320 and the pre-bell timer 11J is also stopped in step 321 to judge that the visitor is out of the bathroom and to end watching, and as described above, 30 minutes in step 306. Stop timer 11F,
In step 307, the family mode is released.

However, in the unlikely event that the inner sensor 11D does not detect the movement of the person in step 314 (NO), and the exit sensor 3E does not detect the movement of the person in step 315 (NO), step 316. If the pre-bell timer 11J has timed out (YES), step 317
Then, the main unit 1 (FIG. 1) is notified of an abnormality in the visitor and the main bell is emitted.

B. Operation in family mode (semi-auto mode).

The operation in this case is shown in FIG. 11, and as described above, the outlet sensor 3E (FIG. 9) does not work.

In this case, it is assumed that the elderly person who is the target person will use it.

When the entrance / exit switch 3X is turned on in step 401 of FIG. 11 (YES), the two-minute timer 11E is set in step 402, and in step 403 it is determined whether the entrance / exit switch 3X is turned off. To be judged.

If it is turned off (YE
S) In step 412, if the two-minute timer 11E is stopped and watching is completed and it is not turned off (N)
O), and proceeds to the next step 404.

That is, the control section 11A (FIG. 9) indicates that the entrance / exit switch 3X has been turned on.
If it is detected through the, the semi-auto mode of the family mode is determined to be set, the 2-minute timer 11E is set, and the 2-minute watching time is set as in the conventional case.

In this state, when the control section 11A detects that the entrance / exit switch 3X is turned off, it determines that the user has finished bathing, and the two-minute timer 11E.
Stop and finish watching.

However, when the control section 11A detects that the entrance / exit switch 3X is not turned off, the control section 11A carries out the operations in and after step 404.

In this case, the operation after step 404 in FIG. 11 is the case where the two-minute timer 11E is set in the operation after step 310 in FIG. 10, and the outlet sensor 3E is replaced with the inlet / outlet switch 3X. The description is omitted here.

C. Operation in washing mode.

The operation in this case is the operation in the washing mode which is added to the operation in the normal mode, as shown in FIG. 12 and surrounded by the broken line (γ and δ).

C-1. Operation until the exit sensor 3E determines whether or not a movement of a person is detected.

In step 501 of FIG. 12, it is determined whether or not the washing mode button 11C has been pushed down. If the washing mode button 11C has been pushed down (YES), the washing mode timer 11G is set in step 509, and then step 502 follows. If you proceed and cannot push it down (NO),
The process directly proceeds to step 502, and in step 502,
It is determined whether the exit sensor 3E has detected a person.

That is, the control section 11A (FIG. 9), when the washing mode button 11C is pushed down, considers that the washing mode is set and sets the washing mode timer 11G.

The set time of the washing mode timer 11G is, for example, 20 minutes.

As a result, when two people are taking a bath and one of them takes a bath, in order to continue watching the remaining person, "touch the sensor when there is a person inside".
The time for confirming the sound output by voice is extended from the conventional 15 seconds (set time of the external detection timer 11H described later) to 20 minutes.

Therefore, a person other than the elderly person who is the subject, for example, the daughter of the elderly person, uses the washing machine in the bathroom to pump up the water in the bath for washing, and to move in and out of the bathroom. However, since the voice confirmation time is extended to 20 minutes as described above, there is no discomfort.

C-2. The operation after determining whether or not the exit sensor 3E detects the movement of a person.

C-2-Operation when motion of a person is detected

In step 502 of FIG. 12, if the exit sensor 3E detects the movement of a person (YES), the external detection timer 11H is set in step 503, and the inner sensor 11D moves the person in step 504. Is detected, and if it is detected (YE
S) In order to set the 2-minute timer 11E, the process proceeds to step 511 described later, and if not detected (NO), in step 505, it is determined whether or not the exit sensor 3E has detected the movement of a person.

That is, when the movement of a person is detected through the exit sensor 3E (FIG. 9), the control section 11A sets the external detection timer 11H as in the conventional case, so that the conventional voice confirmation time is reached. Set 15 seconds.

For example, when the above-mentioned elderly daughter enters the bathroom, the exit sensor 3E is blocked, so that the external detection timer 1
1H is set, and the conventional voice confirmation time of 15 seconds is started.

In this case, since the daughter is using the washing machine, the external detection timer 11H times up and
It is assumed that 5 seconds have passed (NO in step 504 of FIG. 12).
→ NO in step 505 → YES in step 506).

However, as described above, since the washing mode timer 11G is set and the voice confirmation time is extended to 20 minutes, unless the washing mode timer 11G times out (NO in step 507 of FIG. 12), When there is a person inside, please touch the sensor "(step 508 in FIG. 12) is not output as voice.

As described above, by setting the family mode or the laundry mode, a person other than the target person can use the bather watching system without any discomfort.

C-2-Operation when motion of a person is not detected

When the exit sensor 3E does not detect the movement of the person in step 502 of FIG. 12 (NO), it is determined in step 510 whether or not the inner sensor 11D has detected the movement of the person, and it is not detected. In case (NO),
If the same operation is repeated after returning to step 502 and it is detected (YES), the two-minute timer 11E is set in step 511, and it is determined in step 512 whether or not the exit sensor 3E has detected the movement of a person. To do.

Then, in step 512, when the exit sensor 3E does not detect the movement of a person (NO), the operation after step 513 is the same as the operation after step 310 in FIG. 10, and the description thereof will be omitted. .

However, in FIG. 12, as described above, when two people are taking a bath and one of them takes a bath, in order to continue watching the remaining person, Is
Please touch the sensor ”to confirm by outputting by voice (step 508 in FIG. 12). Therefore, in steps 512 and 518, the exit sensor 3E
10 is different from that in FIG. 10 in that the operation after the person has detected the movement of the person (YES) proceeds to the setting of the external detection timer 11H in step 503.

(5) Regarding the telephone connection system 12.

(5) -Configuration. The telephone connection system 12 automatically makes an emergency call to an external telephone, for example, the mobile phone 7 of a cohabitant at the time of the main bell.

In this case, the bather receives the main bell signal C, which is transmitted because the bathroom entrance / exit unit 3 considers that an abnormal situation has occurred and the watching time has elapsed without reaction even by the pre-bell. , A predetermined operation is performed.

As shown in FIG. 13, the telephone connection system 12 includes a control unit 12A, a telephone line control unit 12B, a voice synthesis unit 12C, a telephone number setting unit 12D, and a storage unit 12.
E and a transmission / reception unit 12F.

Of these, the telephone line control unit 12B makes an emergency call by automatically dialing an abnormal situation of a bather through the public line 6 to a predetermined telephone, for example, the mobile telephone 7 at the time of the main bell.

Further, the voice synthesizing unit 8F synthesizes a speech sound indicating an abnormal situation of the bather, for example, "an abnormal situation has occurred" at the time of the main bell.

That is, when the telephone number of the mobile phone 7 owned by the person living together with the bather is input from the telephone number setting unit 12D which is configured by a numeric keypad in advance, the telephone number is temporarily stored in the storage unit 12E. It

It is assumed that the main bell signal C from the bathroom entrance / exit unit 3 is directly received wirelessly via the transmitting / receiving unit 12F as described later (FIG. 14 (A)).

At this time, the telephone number in the storage unit 12E is detected, the mobile telephone 7 having the telephone number is automatically dialed through the telephone line control unit 12B, and the voice synthesis unit 12C performs voice synthesis. A speech sound such as “I did it” is transmitted to the owner of the mobile phone 7.

However, as is well known, there are cases where the owner of the mobile phone 7 is in a place where radio waves do not reach, and in that case, since the above-mentioned abnormal situation of the bather is not transmitted, The telephone line control unit 12B automatically dials the mobile telephone 7 as many times as necessary.

Also, in this case, the mode in which the telephone connection system 12 receives the main bell signal C is shown in FIG.

Of these, FIG. 14 (A) and FIG. 14 (B) are
This is a case of receiving wirelessly, and FIG. 14C shows a case of receiving by wire.

That is, in FIG. 14A, the main bell signal C is wirelessly received directly from the bathroom entrance / exit unit 3, and FIG.
Receives a main bell signal C wirelessly transmitted from the bathroom entrance / exit unit 3 to the main body unit 1 from the main body unit 1.

Further, FIG. 14C shows a main bell signal C wirelessly transmitted from the bathroom entrance / exit unit 3 to the main unit 1.
Is received by wire via the contact 1J and the terminal 12G.

(5) -Operation. Hereinafter, the telephone connection system 12 according to the present invention having the above configuration
The operation of will be described.

For example, when the cohabitant of the bather owns the mobile telephone 7 (FIG. 13), the telephone number of the mobile telephone 7 is stored in advance by operating the telephone number setting section 12D. It is stored in the section 12E.

In this state, for example, a cohabitant goes out with the mobile phone 7.

In this case, as is well known, the bather is watched by, for example, a pre-bell sounding every two minutes, and when the pre-bell does not detect any movement and two minutes pass, the main bell is called. Sounds, and the speaker 12H (at the same time, the speakers of the main unit 1 and the bathroom entrance / exit unit 3) outputs the sound "an abnormal situation has occurred".

At this time, the control section 12A receives the main bell signal C from the bathroom entrance / exit unit 3 via the transmitting / receiving section 12F, for example.
When you directly receive the, the phone number of the storage unit 12E is detected,
The telephone line control unit 12B is controlled to automatically dial the telephone number, and an emergency situation is automatically notified via the voice synthesis unit 12C.

In this case, as described above, the mobile phone 7
In some cases, the cohabitant who is the owner of the mobile phone is in a place where radio waves do not reach, or the mobile phone 7 is turned off. In that case, the call cannot be made.

However, even in such a case, in order to protect the bather, as described above, until the call becomes possible,
It automatically dials any number of times to notify you of emergency situations automatically.

In this way, even if the cohabitant is absent, the bather watching system can be effectively used by notifying the cohabitant who is not present of the abnormal situation.

(6) Regarding ringtone reproduction system 13

(6) -Configuration. This ringtone playback system 13 has a built-in ringtone playback function,
Play the music that bathers like.

As shown in FIG. 15, the ringtone reproducing system 13 includes a control section 13A, an internal sensor 13B, a personal computer interface section (for example, USB I / F) 13C, and
A memory card interface unit (for example, a memory card slot) 13D, a storage unit 13E, and a ringtone reproduction unit 1
3F, an amplifier 13G, a speaker 13H, a ten-key interface unit 13J, and its ten-key 13K.

Of these, the ringtone reproducing section 13F has, for example, the configuration shown in FIG. 16, and includes the FIFO 13F1A and FM.
It is composed of a sound source 13F1B and a chord generating circuit 13F1 for a mobile phone, which includes a D / A converter 13F1C.

The personal computer interface section (for example, USB I / F) 13C and the memory card interface section (for example, memory card slot) 13D are connection sections between the personal computer and the memory card, and the performance data of the ringtone playback section 13F. Enter.

This performance data is temporarily stored in the storage unit 13E. For example, when an elderly person takes a bath, the performance data is read from the storage unit 13F and input to the chord generating circuit 13F1 (FIG. 16). Then, the circuit 13F1 is activated, and a predetermined melody is amplified by the amplifier 13G and emitted from the speaker 13H.

Further, the ten-key pad 13K is a key used when the bather inputs a melody composed by himself / herself. The data is temporarily stored in the storage unit 13E.

Similarly, for example, when an elderly person takes a bath, the melody composed by himself read out from the storage section 13F activates the chord generation circuit 13F1 as performance data (FIG. 16). , And is amplified by the amplifier 13G and emitted from the speaker 13H.

(5) -Operation. Hereinafter, the ringtone reproduction system 1 according to the present invention having the above configuration
The operation of No. 3 will be described.

First, the bather connects a personal computer to the personal computer interface section 13C or a memory card to the memory card interface section 13D, and inputs performance data that suits his taste.

Furthermore, if there is a melody composed by himself, the bather operates the ten-key 13K to input it as performance data via the ten-key interface section 13J.

These performance data are temporarily stored in the storage section 8E as described above.

In this case, the performance data may be Naniwabushi or a jujube if the bather is an elderly person, or may be a recently popular song if the bather is a young person, and his favorite music is the speaker 13H. Anything can flow from the.

In this state, the control unit 13A determines that the inner sensor 1
When a person's movement is detected via 3B, the storage unit 13E is searched and, for example, a chord generating circuit 13F1 which constitutes the ringtone reproduction unit 13F is activated by predetermined performance data.

As a result, the predetermined melody is transmitted to the amplifier 13
Amplified by G and emitted from the speaker 13H, the bather's favorite music flows to the bathroom.

In this case, since the performance data of many songs is normally stored in the storage section 8E, the bather operates the English key (not shown) or the like to cause the control section 13A to operate. Which performance data is used to play ringtone 13F
To give instructions on whether to start.

For example, when the "A" key is pressed, the control section 13A uses the first performance data stored in the storage section 13E, and when the "B" key is pressed. Similarly, the chord generation circuit 13F1 of the ringtone reproduction section 13F is activated by the second performance data.

As described above, by playing the music of one's liking, it is possible to further relax while taking a bath.
