  The configuration of the hot water supply device 27 shown in FIG. 5 is the one disclosed by the present applicant in Japanese Patent Application No. 7-129831, and is already known at the present time, so the description of the configuration of the hot water supply device itself is omitted. In FIG. 5, the bath remote control device 1 and the kitchen remote control device 2 are connected to the control device 3 of the hot water supply device 27, but the kitchen remote control device 2 is installed in the kitchen. Is not provided with a teletext receiving function circuit (receiver circuit) provided in the bath remote control device 1 of the present embodiment or a configuration for displaying text information of the teletext, but other configurations are provided with the bath remote control. Same as device 1. (Of course, the kitchen remote control device 2 can also be provided with functions relating to these character broadcasts.) The operation of each function of the hot water supply device 27 is performed under the control of the control device 3.

  The operations of the hot water supply device 27 such as the hot water supply function, the hot water filling function, and the heat retention function are well known, but will be briefly described below because they are related to the operation of the remote control device. The operation of the hot water supply function is started by turning on the operation switch 35 of the bath remote control device 1 or the kitchen remote control device 2 and opening a hot water tap (not shown) provided at the hot water supply destination of the hot water supply pipe 11 in this state. To do. When the hot water tap is opened, the control device 3 detects the flow rate exceeding the minimum operating flow rate through which the water supply pipe 5 is passed by the flow rate sensor 4, burns the hot water burner 10, and heats the water passing through the hot water heat exchanger 7. The hot water is prepared, and the hot water is supplied to the hot water supply destination through the hot water supply pipe 11.

  In the operation of the hot water supply function, the control device 3 determines whether the hot water temperature is based on detection information of the incoming water temperature by the incoming water temperature sensor 6, the amount of hot water supplied by the flow rate sensor 4, and the hot water temperature (outlet temperature) by the hot water temperature sensor 8. The amount of gas supplied from the gas passage 9 is controlled by the opening amount of a proportional valve (not shown) so that the hot water supply set temperature set by the kitchen remote control device 2 (or the bath remote control device 1) is reached. The hot water supply operation is terminated when the hot water tap at the hot water supply destination is closed. That is, when the flow rate sensor 4 detects the stop of water flow by closing the hot-water tap, the control device 3 shuts off the gas supply to the hot-water supply burner 10 and stops the combustion of the hot-water supply burner 10.

  The operation of the hot water filling function is started by turning on the automatic switch 36 of the bath remote control device 1 (or the kitchen remote control device 2) while the operation switch is turned on. Then, the hot water solenoid valve 13 is opened, and the water passing through the hot water heat exchanger 7 becomes hot water by the combustion heating of the hot water burner 10 as in the operation of the hot water supply function. 14, and is dropped into the bathtub 26 through a recirculation circuit 25 having a return pipe 23 and an outgoing pipe 24. The water level of the bathtub 26 is detected by a pressure sensor as the water level sensor 20, and when the detected water level reaches the set water level of the bathtub set by the hot water supply related switch group 38, the hot water solenoid valve 13 is closed and the hot water filling operation is performed. Ends. In this hot water filling operation, the control device 3 controls the hot water temperature of the hot water heat exchanger 7 so that the hot water filling set temperature is set by the hot water supply related switch group 38.

  In the automatic operation by the automatic switch 36, the operation of the heat retaining function is performed following the operation of the hot water filling function. The operation of this heat retention function is to start the circulation pump 21 for a short time at a predetermined time interval, recirculate hot water in the bathtub 26 and circulate it through the circulation path 25, and the hot water temperature (bath temperature) of the bathtub 26 by the bath temperature sensor 18. Is detected. When the detected bath temperature falls below the allowable range set by the hot water supply related switch group 38 and falls below the allowable range, the circulating pump 21 is driven to recirculate hot water in the bathtub 26 and circulate through the circulation path 25. The reheating is performed by the reheating heat exchanger 15 by the combustion of the bath burner 16. Then, when the temperature detected by the bath temperature sensor 18 reaches the set temperature of the bath, the circulation pump 21 is stopped and the combustion of the bath burner 16 is stopped. As described above, the operation of the heat retaining function (the heat retaining operation) is performed for a predetermined time (for example, 4 hours) after the hot water filling is completed. In the hot water supply device 27 that performs the water retaining function together with the heat retaining function, the water level of the bathtub is monitored by the water level sensor 20, and the hot water solenoid valve 13 is opened when the water level of the bathtub drops beyond the allowable range from the set water level. Then, the amount of hot water that reaches the set water level from the hot water supply heat exchanger 7 side is replenished, and a water retention operation is performed to maintain the bathtub water level at the set water level.

  In FIG. 5, 12 is a flow sensor, 22 is a water flow switch, 19 is a conduit for connecting the discharge port of the circulation pump 21 and the water intake of the reheating heat exchanger 15, and 17 is a gas passage to the bath burner 16. Respectively.

  FIG. 1 shows a first configuration example of the bath remote control device 1 according to the present embodiment. An FM character broadcast receiving unit (text broadcast receiving module) 40 is provided inside a housing case 31 (see FIG. 2). Circuits of a display control unit 41, a bathing / bathing detection unit 42, an individual preference program data creation storage unit 44, and a preference program priority display selection unit 45 are formed on a circuit board and accommodated. In FIG. 1, the bathing / bathing detection unit 42 is shown as a separate circuit from the personalized preference program data creation storage unit 44, the preference program priority display selection unit 45 and the display control unit 41. , 41, 45, and 46. The display screen 32 and the program selection button 39 as the program selection means are provided on the surface of the casing case 31 as shown in FIG.

  The FM teletext receiver 40 includes an antenna, a demodulator circuit, a circuit for separating text information from the signal demodulated by the demodulator circuit, and the like necessary for receiving the teletext. As disclosed in Patent Documents 1 and 3 and the like, since it is known, description of its circuit configuration is omitted. The character information received (received and separated) by the FM character broadcast receiving unit 40 is added to the display control unit 41.

  The display control unit 41 has a built-in memory 43, and character information of each program supplied from the FM character broadcast receiving unit 40 is stored in the memory 43 in association with the program information within a memory capacity. Store in the area. This display control unit 41 is supplied with a switch on / off signal of the teletext switch 37. When an on signal is applied from the teletext switch 37, the text selected by the program selection button 39 is set. When the character information of the broadcast program is displayed on the display screen 32 and an off signal is applied from the character broadcast switch 37, the display of the character information is stopped.

  The bath / bath detector 42 detects that a person has bathed in the bathtub 26 and that he / she has bathed from the bathtub 26 based on a change in the water level of the water level detection signal from the water level sensor 20. This bathing / bathing detection unit 42 includes a clock mechanism (in this example, a timer), and when the water level fluctuates based on the water level detection information of the water level sensor 20, the timer starts the timer operation within the reference time. When the fluctuation level of the water level has reached the reference value, it is determined that the person has bathed in the bathtub when the fluctuation level of the water level reaches the reference value of the water level rise. When the fluctuation amount within the reference time reaches the reference value for lowering the water level, it is determined that the person has taken a bath from the bathtub. The bathing / bathing detection unit 42 bathing and bathing detection (detection) result signals are respectively added to the display control unit 41, individual preference program data creation storage unit 44, and preference program priority display selection unit 45.

  A characteristic point in the present embodiment is that even if the teletext switch 37 is not turned on, it is automatically detected when the water level sensor 20 detects that a person has bathed in the bathtub. The text information of the teletext is configured to be displayed on the display screen 32, and the bather is automatically identified and the text information of the favorite program of the person is displayed on the display screen 32. It is that. In order to execute this unique display mode, the bath remote control device 1 of the present embodiment includes an individual preference program data creation storage unit 44 and a preference program priority display selection unit 45.

  The personal preference program data creation storage unit 44 includes a nonvolatile memory 46, and creates and stores program preference data for each individual bath user. That is, the personal preference program data creation storage unit 44 takes in the detection information of the bathtub water level from the water level sensor 20, and the amount of increase in the water level from the water level based on the water level that is stretched in the bathtub before the person bathes Identify the person who bathed by.

  FIG. 3 shows the amount of water level rise of each person when taking a bath in relation to the water level. The horizontal axis of the graph in FIG. 3 indicates the water level at which hot water is filled, and the vertical axis indicates the bathtub water level. The line a on the graph indicates the water level before the person takes a bath. This water level matches the water level of the hot water filling (water filling set water level), and the angle of the straight line a is 45 degrees. Line b shows the water level due to bathing by the daughter, line c shows the water level due to bathing by the mother, and line d shows the water level due to bathing by the father.

  For example, if the father is 180 cm tall and the weight is 80 kg, the mother is 160 cm tall, the weight is 50 kg, the daughter is 140 cm tall and the weight is 40 kg, and if the father bathes, the water level will be the lowest set level (15 cm) Then, only the lower body is soaked in water, and the abdomen and chest are soaked in water as the water level increases during bathing. The average angle of the line d at this time is about 51 degrees, but the angle when the water level is 20 cm or less is a little steep. This indicates that the cross-sectional area of the abdominal part is considerably larger than the cross-sectional area of the breast part. In the case of a mother, the average angle of the line c is 49 degrees, but the angle is steep at a position where the water level is 22 to 26 cm, indicating that it is a feminine figure. In the case of a daughter, the average angle of line b is 48 degrees.

  As shown in FIG. 3, the amount of water level rise during bathing varies depending on the physique of each person making up the family, and the amount of water level rise during bathing is the water level level before bathing even for the same person. Varies depending on (usually the set water level when filling is completed). The personal preference program data creation storage unit 44 detects the amount of water level rise when a person bathes in the bathtub 26 from the water level detection information of the water level sensor 20, and the amount of water level rise at the time of bathing (water level rise relative to the water level before bathing) Amount) is stored in the nonvolatile memory 46 in correspondence with the water level before bathing. This water level rise value may be stored as a value obtained by subtracting the water level level before bathing from the water level level when bathing in the bathtub (value of the water level rise from the water level level before bathing), or You may memorize | store with the value of the water level at the time of a bathing state (The value of the water level which added the water level rise part to the water level before bathing).

  The personal preference program data creation storage unit 44 further obtains information on the result of the program selection designation of the program selection button 39 based on the operation of the program selection button 39, and from the bath by the detection information of the bathing / bathing detection unit 42. When the bathing is detected, the teletext program last used by the person in the bathtub 26 is stored in the non-volatile memory 46 in association with the stored water level rise value at the time of bathing. Program preference data that associates the amount of water level rise at the time of bathing with the last program used in the bathtub 26 is created and stored for all members of the family.

  The preference program priority display selection unit 45, when the personal preference program data creation storage unit 44 creates and stores the above program preference data, detects a person's bathing by a water level detection signal from the water level sensor 20, and at the time of the bathing The detected value of the water level rise amount is collated with the data of the water level rise amount corresponding to the water level level before bathing in the program preference data to identify the bather. As is clear from FIG. 3, for example, when the bath water level before bathing was 27 cm, the water level increased by 66 mm when the father bathed, increased by 43 mm when the mother bathed, and increased by 34 mm when the daughter bathed, Since the amount of water level rise differs depending on the person's physique, the bather can be easily identified by comparing the amount of water level rise at the time of bathing with the stored program preference data.

  The preference program priority display selection unit 45 specifies the bather, reads the teletext preference program (program name) that the bather last watched in the bathtub at the previous bathing from the program preference data, and reads the program. The display control unit 41 is instructed to display the character information. For example, if the bather was a father and watched a sports program during the previous bath, he ordered the display of sports program text information, and the bather was a mother and watched the weather forecast during the last bath. In this case, the display of character information of the weather forecast program is instructed. When the bather is a daughter and watching the fortune-telling program at the previous bathing, the display of character information of the fortune-telling program is instructed. The display control unit 41 reads out the character information of the program instructed from the preference program priority display selection unit 45 from the memory 43. Then, the display screen 32 is switched from the hot water supply related information display to the character information display, and the read character information is displayed on the display screen 32.

  On the other hand, when the preference program priority display selection unit 45 cannot identify the bather even if the value of the water level rise at the time of bathing detected based on the water level detection signal from the water level sensor 20 is compared with the preference program data. For example, during normal bathing, the mother is immersed in hot water up to the shoulder, but then happens to be immersed in hot water only up to the bottom of the chest. If it becomes unclear whether the bathing is for the mother or the daughter, or because a relative has come to stay and a person with a different physique from the family has bathed, The preference program data is not yet created because the water level rise data is not stored (recorded) in the preference program data or because the bath remote control device 1 is the first bath after the wire connection to the hot water supply device 27. If you do n’t, Commanding the display of the program text information of the start of the broadcast (1st) to the display control unit 41. In response to the instruction, the display control unit 41 reads out the character information of the first program of the teletext (the first news program in the above example) from the memory 43. Then, the display screen 32 is switched from the hot water supply related information display to the character information display, and the read character information is displayed on the display screen 32.

  The display control unit 41 displays the character information on the display screen 32 when detecting that the bather has taken a bath from the bathtub 26 based on the bathing detection signal from the bathing / bathing detection unit 42. Switch to display of hot water related information. In this case, when it is detected (detected) that the bather has taken a bath from the bathtub 26, the display screen 32 is displayed for a predetermined time (for example, 10 seconds) from the time of bathing to display hot water related information (character information is not displayed). ) May be switched to.

  According to the present embodiment, when a person takes a bath in the bathtub 26, the display screen 32 automatically switches from displaying hot water related information (not displaying character information) to displaying character information. When taking a bath, the display on the display screen 32 automatically switches from displaying character information to displaying hot water related information (or automatically displaying to hot water related information after a predetermined time (for example, 10 seconds) after bathing. Therefore, it is possible to enjoy the teletext in the bathtub 26 without operating the teletext switch 37. While bathing from the bathtub 26, hot water-related information is displayed on the display screen 32. If you want to watch text broadcasting while bathing from the bathtub 26, turn on the text broadcasting switch 37. Since the display screen 32 is switched from the hot water supply related information to the character information, the character information can be enjoyed. At this time, if the character broadcast switch 37 is turned off, the display screen 32 is switched from the character information to the display of the hot water supply related information.

  In the present embodiment, since the user's teletext preference program is created and stored as program preference data after bathing, the favorite program is automatically displayed on the display screen 32 when bathing next time. Thus, it is possible to enjoy a favorite program (for example, weather forecast) in the bathtub without performing a program selection operation. If you are interested in another program, operate the program selection button 39 to select another program (for example, a sports program), and that program will be displayed on the display screen 32. Sometimes, the program data of the program preference data is changed from the previous recorded data (weather forecast) to another program (sports program) that was last viewed in the bathtub, so that the program that was updated and stored the next time you take a bath (Sports program) is displayed on the display screen 32. Thus, even when the bather's preference of the program changes, the previously stored program data is updated according to the bather's preference, which is very convenient.

  Furthermore, even when the user's data is not recorded and created in the program preference data or when the bather cannot be specified, when a bathing in the bathtub 26 is detected (detected), a predetermined program is set. Since the character information of the first program of the teletext in this embodiment is automatically displayed on the display screen 32, the user feels relaxed in the bathtub 26 without performing any operation for viewing the teletext. You can enjoy teletext.

  Next, a second configuration example of the bath remote control device 1 according to this embodiment will be described. In the second configuration example, a counter circuit (not shown) is provided in the personal preference program data creation storage unit 44, and the bather specified by the information on the rise in water level at the time of bathing takes a bath in the bathtub 26. Each time a program is selected, the number of times each selected teletext program selected when the program is selected is counted by the counter circuit in association with information on the time when the program is selected, and the time information is added. A value (cumulative value of the number of selections for each program), that is, a count value having time-series time information, is created as program preference data in association with the increase in the water level change at the time of bathing by the bather.

  When the bathing is performed next time, the preference program priority display selection unit 45 has the bather most in the past (all past periods or a predetermined past period such as one month, three months from the present time). The character information of the first program with the largest number of selections (the value of the cumulative selection number is large) is preferentially displayed on the display screen 32, or the first rank program with the largest value of the cumulative selection number is preliminarily displayed. Character information of programs up to a designated rank (for example, the third rank) is repeatedly displayed until the program selection means 39 selects the program. In this case, when a plurality of programs having the same number of cumulative selection times are generated, for example, based on time information (time series information) attached to the count value, a program selected more recently is determined to be higher. The top and bottom of the ranking can be determined.

  Next, the 3rd structural example of the bath remote control apparatus 1 of this embodiment is demonstrated. In the third configuration example, the personal preference program data creation storage unit 44 is similarly provided with a counter circuit (not shown), and a bather specified by the information on the rise in water level at the time of bathing is bathed in the bathtub 26. The counter circuit counts the number of display times of each teletext program displayed when the program is displayed in association with time information at the time (timing) when the program is displayed, Count value with the time information (cumulative value of display count for each program), that is, count value with time-series time information is created as program preference data in association with the rise in water level change at bathing time To do.

  When the bathing is performed next time, the preference program priority display selection unit 45 has the bather most in the past (all past periods or a predetermined past period such as one month, three months from the present time). The character information of the first program with the highest display count (the value of the cumulative display count is large) is preferentially displayed on the display screen 32, or the program with the highest rank of the cumulative display count value is preliminarily displayed. Character information of programs up to a designated rank (for example, the third rank) is repeatedly displayed until the program selection means 39 selects the program. In this case, when a plurality of programs with the same number of cumulative display times are generated, for example, by determining a program displayed more recently as a higher rank based on time information (time series information) attached to the count value, The top and bottom of the ranking can be determined.

  In addition, this invention can take various embodiment, without being limited to the said embodiment example. For example, in the above embodiment, when the bather cannot be specified at the time of bathing, the first (first) program of the teletext is displayed on the display screen 32. You may make it display repeatedly preferentially until a program is selected by the program selection button 39 from the top program of a teletext to the last program.

  In the above embodiment, the character broadcast switch 37 is turned off and the person is not taking a bath, that is, the character information is not displayed on the display screen 32 (character information non-display period). Although the hot water supply related information is displayed on the screen 32, the operation state of the power saving mode may be used instead of displaying the hot water supply related information. The operation in the power saving mode is an operation for turning off the power of one or both of the FM character broadcast receiving unit 40 and the display screen 32 so as not to display information on the display screen 32. FM when the teletext switch 37 is switched from the on state to the off state without bathing, or when it is detected that the bather takes a bath from the bathtub 26 when the teletext switch 37 is off. By configuring the teletext receiver 40 and the display screen 32 to be turned off, it is possible to obtain the operating state of the power saving mode. By setting it as such an operation mode, the power saving of the bath remote control apparatus 1 can be aimed at. Even in such a power-saving mode operation state, when the teletext switch 37 is turned on or even when the teletext switch 37 is off, a person's bathing is detected based on the water level detection signal of the water level sensor 20. When (detected), the display screen 32 is switched from the non-display state in the power saving mode to the character information display state by turning on the power supply in the shut-off state.

  Furthermore, in the first configuration example of the bath remote control device in the above embodiment, when creating the program preference data, the last program viewed in the bathtub 26 is determined as the bather's preference program. The program used for the longest time may be stored as a favorite program of the bather. In this case, the bather measures the time of the program used in the bathtub 26 by a clock mechanism (for example, a timer), and when a plurality of programs are used, the program that has been used for the longest time among them is bathed. The user's favorite program is stored in the favorite program data.

  In the second and third configuration examples of the bath remote control apparatus according to the present embodiment, when the number of program selections and display times are counted, 1 is simply selected every time a program is selected (displayed). In addition to counting (addition counting), the following modifications can be employed. For example, every time a program is selected (displayed), a predetermined unit number of 2 or more is added and counted, and when the program is switched to another program on the way, 1 or more is displayed for the program whose display is turned off. It is possible to adopt a count method in which a predetermined number of units is subtracted, or a configuration in which various rules are defined and the count method according to the rules is executed.

  Furthermore, in the above-described embodiment, the text broadcast switch 37 is provided in the bath remote controller 1.

In addition, a clock display may be displayed on the display screen 32 during the character information display period.

  Furthermore, when displaying character information on the display screen 32, as indicated by the one-dot chain line in FIG. 2, the character information is displayed in the character information display area, and the hot water supply combustion display A and the bath combustion display B are displayed. At least one of them may be displayed by display means such as a combustion lamp, for example. Further, the hot water supply temperature set by the hot water remote control device 1 in the hot water remote control device 1 and the hot water supply setting set by the kitchen remote control device 2 You may make it display the priority display of which temperature is given priority and performing hot water supply operation.

  Furthermore, when a bather cannot be specified by the amount of rise in the water level at the time of bathing, the bather may be specified by adding voice information of the pronunciation of the bather to the judgment material. In this case, the bather's voice data is stored in the memory as additional information in the program preference data. That is, the sound (for example, nasal singing) when the bather is taking a bath is collected by the microphone 33 of the bath remote control device, and the personally identifiable information such as the frequency and intonation of the voice is analyzed and the voice information is displayed as a program. Store as preference data. By adding audio information to the program preference data in this way, even if the bather cannot be identified by the amount of rise in the water level at the time of bathing, the sound collection data at the time of bathing of the bather is obtained from the audio data (information The bather can be identified by comparing with).

  Further, when using broadcast in which text information and radio information such as radio are multiplexed, for example, when the text broadcast switch 37 is pressed for the first time, text information is displayed and voice is provided such as radio. When the teletext switch 37 is pressed, only the text information is displayed. Next, when the teletext switch 37 is pressed, radio or the like is provided. When the teletext switch 37 is pressed, both text information and audio are provided. It is also possible to adopt a configuration in which a series of operations that are performed each time the teletext switch 37 is pressed are repeated.

  Further, the FM character broadcast receiving unit 40 may be integrated with a RAM for storing news once received and a ROM for storing character fonts.

  Furthermore, in each of the above embodiments, the character information is displayed on the display screen 32, but image information, web information, and the like may be displayed in addition to the character information.

  Further, in the above embodiment, the character broadcast is FM multiplex character broadcast. However, the present invention can be applied to AM multiplex character broadcast and TV multiplex character broadcast.
