Description

The present invention relates to a hot water supply system provided with a bathroom remote controller and a kitchen remote controller, which enables simplicity of operation and detection of a dual abnormal state by utilizing voice recognition.

Conventionally, as a hot water supply system, a bathroom remote controller, a kitchen remote controller, etc. are provided with an operation unit having an LCD screen, and an operation for instructing a temperature change or an increase in the amount of hot water is displayed on the LCD screen. It is common to press the button part by hand to perform the desired operation.
However, in order to perform this operation, it is not always possible to accurately operate the buttons and the like displayed on the liquid crystal screen unless the entire system is understood to some extent. For example, when an old man or a child takes a bath and tries to add hot water, the liquid crystal display may not always display a screen for changing the amount of hot water, but may display a screen for changing the temperature. be. On the contrary, when it is desired to change the temperature, the screen for increasing or decreasing the temperature may not be displayed, and the screen for changing the amount of hot water may be displayed. In such a case, you have to change the displayed screen to find the screen with the desired operation, but even if it is easy for someone who knows it, an old man who understands only a part of the system, It causes confusion for children and the like.
In such a case, if the operation by voice recognition is possible, the operation screen requested by intuitive verbal instructions can be made to appear even if the entire system is not understood, which is extremely convenient.

On the other hand, if all of the instructions by voice recognition rely on intuitive verbal instructions, there is a risk that unclear parts may occur in the content and range of the instructions. For example, when there is a voice instruction to raise the temperature, it is a very difficult problem to determine how many times the temperature should be raised. What is the current temperature and how many times do you want it to be, or what to do if there is a limit or an appropriate range for raising and lowering the temperature as a bathtub device and instructions are given beyond that. Whether it should be done is a difficult question.

Patent Document 1 and Patent Document 2 exist as techniques using voice recognition for a conventional hot water supply device, and Patent Document 1 describes a voice command issued by a user and registered voice data in a hot water system. A technique has been proposed in which comparison and collation are performed by voice recognition and hot water supply control is performed when they match. or,
Patent Document 2 proposes a technique for controlling hot water supply by determining whether or not the input voice data is a preset command word.
However, such literature does not propose a technology that captures the technical advantages and disadvantages of both parties and makes effective use of them. A first object of the present invention is to solve the above problem.

In addition, it has recently been noted that bathing is a time of relaxation after the end of one day's activities, and on the other hand, it is physically dangerous for the elderly and the like. For example, when you are in a bathtub, blood flow becomes active and your body temperature tends to rise at once. Furthermore, bathing has the effect of water pressure due to hot water, and your blood pressure rises and your heart rate rises. It has been pointed out that there is a danger of losing consciousness due to the condition of blood pressure.

On the other hand, Patent Document 3 and Patent Document 4 exist, and Patent Document 3 proposes a technique of providing a predetermined biosensor in a water heater to notify a hot water user by an alarm or the like when an abnormality occurs. ing. Further, Patent Document 4 proposes a technique of providing a temperature sensor for measuring the body temperature of a bather and giving a warning to the bather based on the detected body temperature.

However, both proposals require a biosensor, a temperature sensor, and the like, are complicated and expensive in terms of equipment, and their effects are limited to the characteristics of the sensor.
A second object of the present invention is how to solve such a physical danger in bathing by utilizing the technique of voice recognition.

Japanese Unexamined Patent Publication No. 2005-17974 Japanese Unexamined Patent Publication No. 2002-267252 Japanese Patent No. 3188046 JP-A-2004-127027

The subject of the present invention is to combine operation instructions by operating the liquid crystal screen and operation instructions by voice recognition to effectively utilize the technical features of both to promote smooth operation, and to promote smooth operation, and to physically perform bathing.

As shown in FIG. 1, this hot water supply system has a kitchen 10, a bathroom 20, and a water heater 30, the kitchen 10 is provided with a kitchen remote control 11 and a hot water supply port 12, and the bathroom 20 is provided with a bathroom remote control 21 and a bathtub. 22 and a shower 23 are provided. The water heater 30 includes a microcomputer 31, a heat source 32, and a heat source 33 for reheating. The kitchen remote controller 11 and the bathroom remote controller 21 each have a remote controller system control unit in the microphone, as shown in FIG. The control unit includes a voice recognition control unit equipped with a microphone to identify the voice from the user, a voice reproduction control unit equipped with a speaker to reproduce the registered voice, and a liquid crystal display representing a dedicated screen or the like. It is provided with a display control unit having a display control unit and a communication control unit having a communication circuit for controlling mutual communication.
Further, the microcomputer 31 of the water heater 30 includes a communication control unit having a communication circuit with the kitchen remote controller 11 and the bathroom remote controller 21, and a water heater system control unit having a sensor and a heat source control unit.

<Rising temperature>
The hot water supply system is provided with a kitchen remote controller 11 and a bathroom remote controller 21 for instructing the temperature of hot water in a bathtub or shower to rise (hereinafter referred to as temperature rise) or fall (hereinafter referred to as temperature decrease), and the temperature rise using the kitchen remote controller 11 and the bathroom remote controller 21. And the operation of lowering the temperature will be described with reference to the flowchart shown in FIG.
On the LCD screens of the kitchen remote controller 11 and the bathroom remote controller 12, a normal screen displaying the temperature of hot water in a bathtub, automatic bath, repelling, etc. is displayed (see FIG. 3 (A)), and a microphone is displayed in the vicinity thereof. Is provided. Therefore, when the user wishes to raise the temperature of the bathtub or shower, the user is asked to utter a "heating phrase" suggesting a rise in the temperature of the hot water through this microphone. This temperature rising phrase refers to a word suggesting a temperature rise, and examples thereof include words such as "raise the temperature of hot water" and "heat".
When the word "raise the hot water supply temperature" or "heat up" is issued by the user, the voice recognition control unit of the system control unit of the bathroom remote controller 11 or the kitchen remote controller 21 catches this word. Determine if the word corresponds to a "heating phrase".
The determination as to whether or not the phrase corresponds to this "heating phrase" is determined by comparing the words listed in the control unit with the words recognized by voice.
The target person who uses this system is originally a bather, but instructions such as raising the temperature are not limited to this bather. For example, when a child is taking a bath, a family member such as a mother is in the kitchen. The remote control may instruct the temperature rise, etc., and the term "user" is used to include this.

When the voice recognition control unit catches the word uttered by the user and determines that it corresponds to the "heating phrase", the result is transmitted to the display control unit.
Then, on the liquid crystal screen that receives the command from the display control unit, a dedicated screen suitable for instructing the temperature rise is automatically launched.
As a result, even a person who is unfamiliar with the system operation, an elderly person, a child, or the like can start up the dedicated screen required for the temperature rise instruction without hesitation.

On this dedicated screen, a temperature indication zone showing a specific example and range of the temperature that rises from the current hot water temperature of the bathtub etc. is displayed, and as shown in Fig. 3 (B), it is one case when the temperature rises by 1 ° C. The eyes, the second one when the temperature rises by 2 ° C, the third eye when the temperature rises by 3 ° C, and the other fourth eye are displayed as options. For example, when the current temperature is 40 ° C, it is first displayed as 41 ° C, and then 42 ° C, 43 ° C, and others are displayed in that order.
Therefore, the user manually touches the instruction zone indicating the desired temperature rise from this dedicated screen to specify the specific temperature.
When there is an instruction from this dedicated screen, it is transmitted from the display control unit of the kitchen remote controller 11 or the bathroom remote controller 21 to the water heater 30, which will be described later.
As a result, the user can accurately indicate the desired temperature, and when the device has a limit of the temperature rising range, the user does not mistakenly indicate the temperature beyond this.

By the way, at this time, in parallel with the display of the dedicated screen by the liquid crystal display, the instruction by the voice recognition based on the voice input can be used together.
When there is an instruction by hand operation on the above dedicated screen, the instruction content is transmitted to the communication control unit as it is, but on the other hand, when the display control unit without this hand instruction determines, We will shift to this voice recognition method.
The purpose is that the user may have inconvenience in operating the screen because he / she is away from the screen, and may desire it by voice from a remote position. At this time, it is not limited to the manual instruction to the above screen, but it is also possible for the voice recognition control unit to utter the display temperature through the microphone while looking at the dedicated screen displayed by the user. Is.
Specifically, if there is a voice from the user, for example, "Yonjuuni" indicating 42 ° C. through a microphone, the voice recognition control unit catches it and recognizes it as 42 ° C.
At this time, it is assumed that children and the like are not good at pronouncing "Yonjuuni", which may cause a malfunction in voice recognition.
Therefore, as shown in FIG. 3B, it is also effective to color-code the temperature indicator zone on the dedicated screen for each eye and have the color pronounced. For example, 41 ° C is color-coded as "blue", 42 ° C is "yellow", 43 ° C is "orange", and the others are "brown". It is a means to increase the recognition rate by subscripting "brown" and having the user pronounce the color at the desired temperature.
When this voice instruction is given, the instructed temperature is displayed on the screen in order to confirm whether or not the recognition is correct, and for example, "Are you sure you want 42 ° C?" Is displayed. The same content may be uttered from the voice reproduction control unit through a speaker.
As a result, even a child or the like who is not good at pronouncing complicated words can accurately instruct the rise or fall of the hot water temperature while enjoying watching the color.

In response to the above response, answer "No" or "Yes" by either liquid crystal display or voice recognition in the same way as above.
The instruction content is transmitted from the voice control unit of the kitchen remote controller 11 or the bathroom remote controller 12 to the communication control unit, and is transmitted from the communication circuit of the water heater 30 to the communication control unit through the communication circuit.
The communication control unit that receives this is transmitted to the water heater system control unit, and the temperature rise is started from the heat source control unit.
The selection between the above voice input and the manual input on the screen has advantages and disadvantages, and is based on the selection according to the user's circumstances.

<Temperature drop>
On the contrary, this system recognizes the "lowering temperature phrase" that suggests the decrease in hot water temperature generated by the user by voice, and either touches the zone indicating the decrease in temperature on the dedicated screen by hand or instructs the corresponding temperature by utterance. It also has a means to instruct the temperature of the hot water to drop.
The content is almost the same as the case of the above-mentioned temperature rise, but instead of the above-mentioned "heat-up phrase", a "temperature-lowering phrase" suggesting a decrease in hot water temperature is used. This temperature-lowering phrase includes words that would generally suggest a temperature drop, such as "lower the temperature of hot water", "warm" and the like.
In addition, on the dedicated screen, for example, the first eye when the temperature drops by 1 ° C, the second eye when the temperature drops by 2 ° C, the third eye when the temperature drops by 3 ° C, and the other fourth eye are displayed from the current hot water temperature. Will be done. When the current temperature is 40 ° C, it is displayed as 39 ° C, 38 ° C, 37 ° C, etc. in the order of increasing order.
Others are the same as in the case of the above temperature rise (not shown).

<Additional bath>
In addition, this system includes a kitchen remote controller 11 and a bathroom remote controller 21 for instructing an increase in the amount of hot water in the bathtub (additional hot water), and an operation for increasing the amount of hot water using the kitchen remote controller 11 and a bathroom remote controller 21 will be described based on the flowchart shown in FIG. ..
As described above, the liquid crystal screen displays the normal screen when the temperature rises, but the footbath does not display the normal screen. Therefore, if the user wishes to increase the amount of hot water, ask the user to utter a "additional hot water phrase" that suggests an increase in the amount of hot water in the bathtub. This footbath phrase refers to a word that suggests an increase in the amount of hot water, and examples thereof include words such as "add hot water" and "increase hot water".
When the word "add hot water" or "add more hot water" is issued by the user, the voice recognition control unit of the system control unit of the bathroom remote controller or kitchen remote controller catches this phrase, and this phrase is used. Judge whether or not it corresponds to the "additional bath phrase".
In this "additional hot water phrase", words that are likely to correspond to the control unit are listed, and the presence or absence of the corresponding words is determined by comparing with the words recognized by voice.

When the voice recognition control unit catches the word uttered by the user and determines that it is a "additional hot water phrase", the result is transmitted to the display control unit.
Then, on the liquid crystal display screen that receives the command from the display control unit, a dedicated screen suitable for instructing the increase in the amount of hot water is automatically launched.
On this dedicated screen, a hot water amount instruction zone showing a specific example and a range of the hot water amount to be increased is displayed. For example, as shown in Fig. 3 (C), the first square when the number is increased to the first row, the second square when the number is increased to the second row, the third square when the number is increased to the third row, and the other four. Eyes are displayed as choices. For example, 10L is displayed at first, and 30L, 60L, and others are displayed in the following order.
Therefore, the user manually touches the instruction zone indicating the desired amount of increased hot water from this dedicated screen to indicate a specific value.
When there is an instruction from this dedicated screen, it is transmitted from the display control unit to the water heater described later.

At this time, in parallel with the display of the dedicated screen by the liquid crystal display, the instruction by voice recognition based on the voice input can be used together.
Specifically, if there is a utterance from the user through a microphone, for example, "Rokuju" indicating 60L, the voice recognition control unit catches it and recognizes it as 60L.
At this time, it is assumed that children and the like are not good at pronouncing "Rokuju".
Therefore, as shown in FIG. 3C, it is also effective to color-code the hot water amount instruction zone for each eye and have the color pronounced. For example, 10L is color-coded as "blue", 30L as "yellow", 60L as "orange", and the others as "brown", and "blue", "yellow", "orange", "brown" as needed. And ask the user to pronounce the color of the desired amount of hot water.
When this voice instruction is given, the instructed amount of hot water is displayed on the screen in order to confirm whether or not the recognition is correct, and for example, "Do you want to increase 60L?" Is displayed. The same content may be uttered from the voice reproduction control unit through a speaker.

In response to this reply, answer "No" or "Yes" by either liquid crystal display or voice recognition in the same way as above.
The instruction content is transmitted from the voice control unit to the communication control unit, and is transmitted from the communication circuit of the water heater to the communication control unit through the communication circuit.
The communication control unit that receives this is transmitted to the water heater system control unit, and the hot water addition is started from the heat source control unit.
The selection between the above voice input and the manual input on the screen shall be made according to the circumstances of the user.

<Automatic selection of bathtub / shower>
The case where the temperature of the bathtub 22 or the shower 21 is raised or lowered has been described above, but when selecting either the bathtub or the shower, the user may be allowed to select either of them. The additional system shown allows this to be done automatically regardless of the user's choice.
As shown in FIG. 4, when the user issues a "heating phrase" or a "cooling phrase" suggesting an increase or decrease in the sound of hot water, the additional system determines whether the shower is in use at that time. To judge.
In that determination, a valve U provided in the middle of the flow path from the heat source to the bathtub, a flow meter A provided in the flow path from the water supply system to the heat source, and a flow path between the valve U and the bathtub are provided. A flow meter B is used.
At the valve U, the flow rate A on the water supply side, and the flow rate B on the hot water filling side, a) the valve U is closed and the flow rate A is A> 0, or b) the valve U is open. If the flow rate (AB)> 0, it is determined that the shower is in use.
Other than that, it is judged that the shower is not used. This is because one hot water supply flow path is switched by the valve U, so it can be determined from the position of the valve which hot water is being supplied.

Based on this judgment, when it is determined that the shower is in use, when the above "heating phrase" or "lowering temperature phrase" is issued by the user, the corresponding LCD display dedicated screen displays " Display a sentence that clearly indicates that the target for raising or lowering the temperature is the shower, such as "How many times do you want to raise the hot water supply temperature of the shower?"
If it is determined that the shower is not in use, a sentence such as "How many times do you want to raise the bath temperature?" Is displayed to clearly indicate that the target for raising or lowering the temperature is the bathtub.
When operating according to this additional system, the user is automatically selected by operating the system without instructing himself that the subject of heating or cooling is either a shower or a bathtub.

<Watching function>
Next, the monitoring function of this system will be described with reference to FIG. 7.
This watching function is a function of watching over a bather by determining whether or not a person using the bathtub 22 or shower 23 of the bathroom 20 (hereinafter referred to as a bather) has some physical abnormality. To say.
The monitoring function is divided into a first step of recognizing a positive response from the bather after the function starts and a second step of recognizing a state in which there is no response from the bather under certain conditions.
Before entering each step, in principle, the start operation is input from the kitchen remote controller side to start the watching function. This operation may be either voice input or screen input.

Then, the first step is started, and the first step starts from the setting of the call start time.
The call start time refers to the time during which the second step should function after the first step has been made to function for a certain period of time, and is defined so that each of them is divided into predetermined times to exert two types of functions.
For example, when the call start time is set to 5 minutes, the operation of the first step is performed for 5 minutes, and then the operation of the next second step is started.
When this call start time is set, the voice recognition control unit of the bathroom remote controller operates to recognize the "worry phrase" that may be emitted from the bather through the microphone within this set time.
This "worry phrase" is a collection of words emitted by a bather that may cause some physical abnormality. For example, it refers to words such as "Tasukete", "Dareka", "Oi", and "Taihenda" that are presumed to have an unusual condition in the body. The recognition of this word is made by comparison with the words listed in the voice control unit, but it may be further evolved by the learning function.

When this "worry phrase" is recognized by the voice recognition control unit of the bathroom remote controller, the bather positively notifies that some abnormal situation has occurred. Therefore, this is regarded as the occurrence of an abnormal situation. Notify the kitchen remote control.
The means of this notification is, for example, either announcing by voice "I confirmed an abnormality in the bath" or displaying it on the LCD screen, or one of them.
Since the notification is when an abnormality has occurred in the bather, the notification is not limited to the notification to the kitchen remote controller, and includes a means that can be received even at a remote place such as a notification to a family member by a mobile phone. Is desirable.

Then, when the predetermined time has passed and no abnormality is confirmed in the first step, the process automatically shifts to the second step based on the setting of the call start time.
In this second step, a state in which there is no response from the bather is recognized under certain conditions, and this is judged to be abnormal. In order to recognize this "absent" state, the following conditions are required. Become.
One of the conditions is that a "call" that should ask the bather for some kind of response is pronounced as a voice.
The purpose of this call is to have the bather announce the condition by his / her own voice through the speaker, and therefore, the call is a word that prompts the announcement of the condition.
For example, even if it is a casual tone such as "How is the hot water?" Or "How are you feeling?", It is a word that can surely ask for a reply.
This call is made from the voice reproduction control unit through the speaker, and is appropriately selected from the vocabulary prepared for the call by the voice control unit and pronounced.
It is preferable that the vocabulary of the calling words is larger. For example, when the calling is repeated multiple times, it is preferable that the words are different from the previous words instead of the same words in order to draw the attention of the bather.

The second condition is to set a certain time limit as the standby time for this call.
It takes a certain amount of time for the bather to respond to the call, and a minimum amount of time is secured, while if it is too long, the bather will continue to wait even though the response cannot be expected, which is effective. I am afraid to lose.
The standby time is set by balancing the two, for example, 30 seconds, and the voice recognition control unit is operated so that the presence or absence of a response within this time frame can be detected.

Now, under such conditions, the voice recognition control unit determines whether or not the "safety phrase" can be confirmed.
This "safety phrase" is a word that is recognized as having responded to the above call.
For example, words such as "good hot water" and "just right" can be judged to be positive in response to the call, and even words such as "hot" and "slimy" can be used for the call. Since it is a word issued in response, it is included in the relief phrase.
In such a case, it is judged that the physical or mental abnormality of concern is unlikely to exist, and the watching function is terminated.

On the other hand, under such conditions, if the "safety phrase" cannot be confirmed, the watching function from a different standpoint from the first step is exhibited.
That is, if there is no pronunciation of the voice within the standby time despite the above call, if there is a utterance but it is just "Ah", "Wu", etc., or if there is a utterance of a word, If it is not a word that responds to the call, or if it is meaningless as a word, the "safety phrase" cannot be confirmed.
In such a case, it is recognized that a serious abnormality may be hidden.
For example, in elderly people, the high temperature and pressure of hot water tend to cause an increase in blood pressure and pulse, resulting in a feeling of illness, a state of unconsciousness, and a disturbance of consciousness such as fainting. In such a case, even if the above-mentioned call is made, it is not possible to respond to the call, and there is a concern that even the call is not conscious.
This corresponds to the case where the above "safety phrase" cannot be confirmed, and can be an important opportunity to know the existence of danger.
Therefore, in this system, it is judged that the situation deserves to issue a warning by confirming this state.
When such a state is detected by the voice recognition control unit of the bathroom remote controller, it is notified to the kitchen remote controller as described above, and is displayed by voice or on the LCD screen as a possibility of an abnormal situation occurring.
In this case, since there is a possibility that urgency is required, it is desirable to take measures not only to notify the kitchen remote controller but also to those other than family members.

At this time, if further certainty is desired in the monitoring by the above-mentioned call, it is possible to make the call again and again while changing the words of the call and the setting of the standby time.

By the above means, the monitoring function from a position different from that of the first step is exhibited, and an effective means of avoiding danger from a position different from the conventional one can be obtained.

The monitoring functions of the first step and the second step are combined to perform dual protection.
Therefore, it may be performed only once during bathing, but it is also optional to repeat it multiple times according to the situation of the bather such as the elderly.
