Is installed.

  Next, the memorial function of the hot water supply / memorial device 2 will be described.

  The memorial pipe 46 is composed of a return pipe 461 that guides the bathtub hot water BW to the combusting combustion chamber 8, and an outward pipe 462 that guides the bathtub hot water BW to the bathtub 6. The return pipe 461 and the forward pipe 462 are connected to the circulation fitting 48 of the bathtub 6. In the bath water purging process, the water is guided to the heat exchanger 14 through the return pipe 461, and is subjected to additional heating, and reaches the bathtub 6 through the forward pipe 462.

  The return pipe 461 is provided with a bath temperature sensor 50, a water level sensor 52, a circulation pump 54, and a running water switch 56. The bath temperature sensor 50 detects the temperature of the flowing bath water BW. The water level sensor 52 detects the water level of the bathtub hot water BW of the bathtub 6 as a pressure. The circulation pump 54 is a power source for flowing the bathtub hot water BW through the memorial pipe 46. The running water switch 56 detects the flow state in the memorial pipeline 46. When the circulation pump 54 is driven, the presence or absence of flowing water is detected by the flowing water switch 56, and when the hot water BW that can be circulated exists in the bathtub 6, the flowing water switch 56 is turned on. Between the water level sensor 52 and the circulation pump 54, the above-mentioned pouring pipe line 38 is connected, and hot water or water is poured into the remedy pipe line 46 side.

  The forward pipe 462 is provided with a bath temperature sensor 65 and a three-way valve 66. The bath temperature sensor 65 detects the temperature of the bath water BW which is heated in memory and flows to the bathtub 6. One side of the three-way valve 66 is connected to a pipe line for flowing the bathtub hot water BW to the bathtub 6, and the other side is connected to a drain pipe line 70.

  The hot water supply / remembrance device 2 is provided with a control device 110 that controls operations such as hot water supply control and control of the rehabilitation process. The control device 110 communicates with the external terminal 114 to control the hot water supply command and the like. Examples of the external terminal 114 include a system dedicated terminal or a smartphone (hereinafter referred to as “smartphone” as appropriate) in which a control application is installed.

  Next, the configuration of the three-way valve 66 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a three-way valve unit. In FIG. 2, the same parts as those in FIG. Moreover, the structure shown in FIG. 2 is an example, and is not limited to this.

  For example, as shown in FIG. 2A, the three-way valve 66 has an inflow side connection port 118 for connecting the forward pipe 462 of the memorial pipe 46 at the lower part. At the connection port 118, the bath water BW that flows through the forward pipe 462 of the memorial pipe 46 flows in during the memorial process. One connection port (the left connection port in the figure) 120 on the outlet side of the three-way valve 66 is connected to a circulation fitting 48 installed in the bathtub 6. The other connection port (the right connection port in the figure) 122 on the outlet side of the three-way valve 66 is connected to the drain pipe 70.

  A motor 124 for operating the valve is installed on the top of the three-way valve 66. As shown in FIG. 2B, for example, a spherical valve portion 127 in which a flow path 125 is formed is configured inside the three-way valve 66. By switching the valve portion 127 to the left and right by the motor 124, the communication destination of the inflow side connection port 118 is switched to the left connection port 120 in the drawing or the right connection port 122 in the drawing. That is, based on a control signal from the control device 110, the flow from the heat exchanger 14 for remedy to the circulation fitting 48 and the flow from the heat exchanger 14 to the drain pipe 70 are switched.

  From the above configuration, if the circulation pump 54 is driven in a state where the valve portion 127 is switched so that the communication destination of the inflow side connection port 118 becomes the right connection port 122 (drainage pipe 70), As indicated by the arrow in FIG. 1, the bathtub hot water BW flows and flows through the circulation fitting 48 → the return pipe 461 → the forward pipe 462 → the three-way valve 66 → the drain pipe 70. That is, in the hot water supply / remedy apparatus 2 according to this embodiment, the hot water BW is discharged without opening the drain plug 6a by switching the three-way valve 66 installed in the memorial pipe 46 to the drain pipe 70. It can be done.

  In the present embodiment, the location of each person is detected at a place where an external terminal (for example, a smartphone) 114 associated with the person is present. And it controls according to the place. Therefore, a method for detecting the location where the smartphone 114 is located (the position of the smartphone 114) will be described next.

  The smartphone 114 is equipped with a function of communicating using Bluetooth (registered trademark). The position of the smartphone 114 can be detected by using this Bluetooth Proximity Profile (PXP). That is, ProximityProfile (PXP) is a profile that can determine the distance of a paired device, and therefore can determine whether or not the paired device has come within a predetermined distance. This profile is also used for security measures such as locking the PC when the user leaves the desk.

  For example, a Bluetooth communication device may be provided with a Bluetooth communication function (Bluetooth communication device) capable of transmitting and receiving dimming intensity to the dimming function unit of the lighting 602 of the bathroom 600. This makes it easy to install and secure a power source.

  For example, as shown in FIG. 3, when a Bluetooth communication device is arranged in the illumination 602-1 near the entrance 601 of the bathroom 600, a device (smartphone) paired with the Bluetooth communication device is used. Whether or not the user has entered the bathroom 600 can be determined as follows. That is, as the dressing room 500 approaches the bathroom 600, the distance to the device (smartphone) paired with the Bluetooth communication device approaches. And after approaching the vicinity of the entrance / exit 601 of the bathroom 600, it will leave | separate as it advances into the bathroom 600. Thus, after approaching and within a predetermined distance, it is determined that the smartphone is in the bathroom if the user leaves. It can be similarly determined whether or not the user leaves the bathroom 600. That is, as the smartphone in the bathroom approaches the entrance / exit 601 of the bathroom, the distance from the Bluetooth communication device approaches and falls within a predetermined distance, and then leaves. Thus, if the smartphone in the bathroom once approaches and falls within a predetermined distance and then leaves, it is determined that the smartphone has left the bathroom 600.

  On the other hand, when a Bluetooth communication device is arranged in the lighting 602-2 in the back of the bathroom 600, whether or not a device (smartphone) paired with the Bluetooth communication device has entered the bathroom 600 is as follows. Can be determined. That is, as the dressing room 500 approaches the bathroom 600, the distance from the device (smartphone) paired with the Bluetooth communication device approaches, and when the distance further approaches and falls within a predetermined distance, the smartphone is in the bathroom. Is determined. It can be similarly determined whether or not the user leaves the bathroom 600. That is, as the smartphone in the bathroom approaches the entrance / exit 601 of the bathroom, the distance from the Bluetooth communication device increases, and further away when the smartphone leaves the bathroom. As described above, if the smartphone in the bathroom is separated and separated by a predetermined distance or more, it is determined that the smartphone has left the bathroom 600.

  As described above, when the position is grasped by Bluetooth, there are two patterns, that is, a pattern in which the Bluetooth communication device is arranged and then moves away and a pattern that approaches and moves away unilaterally. By grasping which pattern is applicable, it is possible to accurately determine whether or not the smartphone is in the bathroom. Note that the location where the Bluetooth communication device is disposed may be set by the user operating the device or may be learned by making several determinations.

  Similarly, whether or not the smartphone 114 is in the dressing room 500 can be grasped by the distance from the Bluetooth communication device 501. The Bluetooth communication device 501 may be installed on the wall or on the washstand 502.

  Next, specific control logic of the bath control apparatus according to the present invention will be described with reference to a flowchart.

  FIG. 4 is a flowchart showing specific contents of automatic button processing executed by the bath control apparatus. The following processing is repeatedly executed at a predetermined time cycle.

  In step S11, it is determined whether or not the automatic button of the smartphone 114 is turned on. If the determination result is positive, the process proceeds to step S12. If the determination result is negative, the process proceeds to step S14.

  In step S12, the automatic button flag is turned on.

  In step S13, the hot water supply / memorial device 2 is operated to start hot water filling.

  In step S14, it is determined whether or not the automatic button flag is on. If the determination result is positive, the process proceeds to step S15, and if the determination result is negative, the process is temporarily exited.

  In step S15, it is determined whether or not the minimum set amount of hot water and the energy-saving hot water temperature have been reached. If the determination result is positive, the process proceeds to step S16, and if the determination result is negative, the process is temporarily exited.

  Here, the minimum set amount of hot water, the minimum set hot water temperature, and the energy-saving hot water temperature will be supplemented. For example, when each family member owns a smartphone 114, the minimum set hot water temperature and the minimum hot water temperature are the lowest hot water temperature and the lowest hot water temperature set by the family at home. It is. In other words, if there are three family members (three smartphones) who have registered the control application and all three are at home, the lowest setting is the lowest of the hot water volume and hot water temperature set by those three people. The amount of hot water and the minimum set hot water temperature. If there are three family members (three smartphones) who have registered the control app, but only two people are at home (if one person has not returned home), the amount of hot water and hot water set by the two at home Among the temperatures, the lowest is the minimum set amount of water and the minimum set temperature. In the case of a single household (living alone), the hot water volume and hot water temperature set by the person are the minimum hot water volume and the minimum hot water temperature. The energy-saving hot water temperature is a hot water temperature slightly lower than the minimum set hot water temperature (for example, a hot water temperature 3 ° C. lower than the minimum set hot water temperature). In step S15, it is determined whether or not the hot water amount has reached the minimum set hot water amount and the hot water temperature has reached the energy-saving hot water temperature.

  In step S16, the hot water filling is completed and notified.

  In step S17, the hot water supply / memorial device 2 is set to the sleep mode.

  In step S18, the automatic button flag is turned off.

  FIG. 5 is a flowchart showing the specific contents of the bathing pretreatment executed by the bath control device.

  In step S <b> 21, it is determined whether or not a person has moved to a dressing room 500 from a place other than the bathroom 600. If the determination result is positive, the process proceeds to step S22. If the determination result is negative, the process proceeds to step S25. In this embodiment, the determination is made based on whether or not the smartphone 114 associated with each person has moved from a place other than the bathroom 600 to the dressing room 500. Whether or not the smartphone 114 has moved from a place other than the bathroom 600 to the dressing room 500 can be determined by, for example, the Bluetooth communication function.

  In step S22, the preparation flag is turned on.

  In step S23, the sleep mode of the hot water supply / remedy device 2 is canceled.

  In step S24, the circulation pump 54 is operated to detect the temperature of the bathtub hot water BW with the bath temperature sensor 50, and the water level sensor 52 detects the water level (hot water amount) of the bathtub hot water BW of the bathtub 6 as a pressure.

  In step S25, it is determined whether or not the preparation flag is on. If the determination result is affirmative, the process proceeds to step S26, and if the determination result is negative, the process is temporarily exited.

  In step S26, a preparation process is executed. Specific processing contents will be described later.

  FIG. 6 is a flowchart showing specific contents of the preparation process executed by the bath control apparatus.

  In step S261, it is determined whether or not the person who has moved to the dressing room 500 has been adjusted to the set hot water temperature and the set hot water volume registered in the smartphone 114 associated with the person. If the determination result is negative, the process proceeds to step S262, and if the determination result is positive, step S262 is skipped.

  In step S262, the hot water supply / remembrance device 2 is operated so that the set hot water temperature and the set hot water amount registered in the smartphone 114 are obtained. When it is necessary to increase the hot water temperature and the amount of hot water, the hot water temperature and the amount of hot water can be increased by taking the water W from the water supply port 16 and supplying the hot water. If the amount of hot water becomes excessive, the bathtub hot water BW is discharged without opening the drain plug 6a by switching the three-way valve 66 as described above. In addition, when a person who likes a high hot water bathes first and then a person who prefers a lower hot water bathes, it is necessary to lower the hot water temperature. In this case, the hot water temperature can be lowered by increasing the opening degree of the bypass water control valve 32 and supplying the water W taken from the water supply port 16 to the bathtub 6. In this way, it is possible to adjust the set hot water temperature and the set hot water amount registered in the smartphone 114.

  In step S263, it is determined whether or not a predetermined time has elapsed since the person (smartphone 114 linked to the person) moved to the dressing room 500. While the determination result is negative, step S264 is skipped, and when the determination result is affirmative, the process proceeds to step S264.

  In step S264, the lighting of bathroom 600 is turned on.

  In step S265, it is determined whether or not the adjustment of the hot water temperature and the hot water amount is completed and the lighting of the bathroom 600 is turned on. While the determination result is negative, step S266 is skipped, and when the determination result is affirmative, the process proceeds to step S266.

  In step S266, the preparation flag is turned off.

  FIG. 7 is a flowchart showing specific contents of bathroom processing executed by the bath control device.

  In step S <b> 301, it is determined whether a person (smartphone 114 linked to the person) is in bathroom 600. If the determination result is affirmative, the process proceeds to step S302. If the determination result is negative, the process temporarily exits. Note that whether or not a person is in the bathroom 600, that is, whether or not the smartphone 114 associated with the person is in the bathroom 600 can be determined by, for example, the Bluetooth communication function.

  In step S <b> 302, it is determined whether a person has entered the bathtub 6. If the determination result is affirmative, the process proceeds to step S303, and if the determination result is negative, the process proceeds to step S306.

  The determination as to whether or not a person has entered the bathtub 6 may be made based on the water level sensor 52, for example. The water level sensor 52 is a sensor that detects the water level of the bath water BW of the bathtub 6 as a pressure. If the water level sensor 52 detects an increase in water level (pressure), it can be determined that a person has entered the bathtub 6. Further, it may be estimated (indirectly detected) that a person has entered the bathtub 6 based on the elapsed time since entering the bathroom 600. Furthermore, it may be estimated (indirectly detected) that a person has entered the bathtub 6 when a hot water outlet 26 such as a shower stops and a predetermined time has passed.

  In step S303, the bathtub entering flag is turned on.

  In step S304, the illumination intensity of the bathroom 600 is adjusted. Even if it is a little dark, it may turn off completely. Further, the illuminance may be adjusted to zero, that is, may remain bright without adjustment. How to adjust is performed according to a set value registered in the smartphone 114.

  In step S305, the illumination intensity of the dressing room 500 is adjusted. In this case as well, it may be slightly darkened or completely turned off according to the illuminance of the bathroom 600. Also, the illuminance need not be adjusted to zero, that is, not adjusted. The illumination of the dressing room 500 may be turned off while the illuminance of the bathroom 600 remains bright. How to adjust is performed according to a set value registered in the smartphone 114.

  In step S306, it is determined whether or not the bathtub entry flag is on. If the determination result is affirmative, the process proceeds to step S307, and if the determination result is negative, the process is temporarily exited.

  In step S307, it is determined whether or not a person is going out of the bathtub 6. If the determination result is affirmative, the process proceeds to step S308. If the determination result is negative, the process proceeds to step S309. In addition, since the water level sensor 52 detects the water level of the bathtub hot water BW of the bathtub 6 as a pressure, for example, if the water level (pressure) falls, the determination whether the person is going out of the bathtub 6 will be carried out. What is necessary is just to determine with getting up at 6 and going out of the bathtub 6 from now on.

  In step S308, the bathtub exit flag is turned on.

  In step S309, it is determined whether the bathtub exit flag is on. If the determination result is negative, the process proceeds to step S310, and if the determination result is positive, the process proceeds to step S311.

  In step S310, the in-tub processing is executed. Specific processing contents will be described later.

  In step S311, a bathtub exit process is executed. Specific processing contents will be described later.

  FIG. 8 is a flowchart showing specific contents of the in-tub processing executed by the bath control device.

  In step S3101, it is determined whether or not the smartphone 114 is in a state. If the determination result is affirmative, the process proceeds to step S3102. If the determination result is negative, the process proceeds to step S3106. Whether or not the smartphone 114 is placed may be determined by a signal from an acceleration sensor built in the smartphone 114.

  In step S <b> 3102, it is determined whether the display surface of the smartphone 114 is close to the wall of the bathroom 600, that is, whether the display surface is directed to the wall of the bathroom 600. If the determination result is negative, the process proceeds to step S3103, and if the determination result is positive, the process proceeds to step S3104. Whether the display surface of the smartphone 114 is close to the wall of the bathroom 600 can be determined by whether the change can be detected by the illuminance sensor of the smartphone 114 when the illuminance of the display surface of the smartphone 114 is changed. That is, if the display surface of the smartphone 114 is close to the wall of the bathroom 600, the reflected light of the light emitted from the display surface of the smartphone 114 can be detected by the illuminance sensor of the smartphone 114.

  In step S3103, color gradation illumination is performed with normal illuminance.

  In step S3104, color gradation illumination is performed with an illuminance brighter than normal.

  In step S3105, music is played. What kind of music is played is performed based on setting information registered in the smartphone 114. For example, when a music genre is designated and healing music is to be played, a high-quality bathroom space can be produced by selecting and playing healing music such as genre number 26 of the ID3 tag from the smartphone 114. Instead of selecting music from the smartphone 114, a music distribution service or the like may be used.

  In step S3106, it is determined whether the smartphone 114 is currently performing color gradation illumination. If the determination result is affirmative, the process proceeds to step S3107. If the determination result is negative, the process is temporarily exited.

  In step S3107, the color gradation illumination is stopped.

  FIG. 9 is a flowchart showing the specific contents of the bathing process executed by the bath control device.

  In step S3111, it is determined whether or not the smartphone 114 is in a possessed state. If the determination result is negative, the process proceeds to step S3112, and if the determination result is positive, the process proceeds to step S3113. Note that whether or not the smartphone 114 is being held may be determined by a signal from an acceleration sensor built in the smartphone 114.

  In step S3112, the lighting of the bathroom 600 is adjusted, and if it is darkened in step S304, it is brightened. If it is too bright, the illuminance difference is large and the eyes are dazzled, and it may be difficult to straddle the edges of the bathtub 6, so the eyes are brightened to the extent that the eyes are not dazzled. For example, the illuminance is increased so that the difference in illuminance is about 70% at the maximum.

  In step S3113, the color gradation illumination is stopped.

  In step S3114, the lighting of bathroom 600 is adjusted. In step S3112, the illuminance is increased, but the illuminance is further increased to return to the normal state. Also in this case, if the difference in illuminance is too large, the eyes will be dazzled, so the eyes are brightened to the extent that they are not dazzled. For example, the illuminance is increased so that the difference in illuminance is about 70% at the maximum.

  In step S3115, the illumination of the dressing room 500 is adjusted. If it is darkened in step S305, the illuminance is increased and the normal state is restored.

  In step S3116, music is stopped.

  In step S3117, the bathtub entry flag and the bathtub exit flag are turned off.

  FIG. 10 is a flowchart showing specific contents of the post-bath processing executed by the bath control device.

  In step S <b> 41, it is determined whether or not the person (smartphone 114 linked to the person) has moved from the bathroom 600 to the dressing room 500. If the determination result is positive, the process proceeds to step S42, and if the determination result is negative, the process proceeds to step S44. Note that whether or not the smartphone 114 has moved from the bathroom 600 to the dressing room 500 can be determined by, for example, the Bluetooth communication function.

  In step S42, the bathing end flag is turned on.

  In step S43, the hot water supply / memorial device 2 is set to the sleep mode.

  In step S44, it is determined whether or not the bathing end flag is on. If the determination result is affirmative, the process proceeds to step S45, and if the determination result is negative, the process is temporarily exited.

  In step S45, a bathing end process is executed. Specific processing contents will be described later.

  FIG. 11 is a flowchart showing specific contents of the bathing end process executed by the bath control device.

  In step S451, it is determined whether or not the person (smartphone 114 associated with the person) has moved out of the dressing room 500. While the determination result is negative, step S452 is skipped, and when the determination result is affirmative, the process proceeds to step S452. Note that whether or not the smartphone 114 has moved out of the dressing room 500 can be determined by, for example, the Bluetooth communication function.

  In step S452, the bathroom 600 and the dressing room 500 are turned off.

  Next, processing of the bath control device will be described along each scene. In the following description, step numbers of the flowcharts are described as appropriate so that the correspondence with the flowcharts can be easily understood.

(When the automatic button of the smartphone application is turned on from off)
If the automatic button of the smartphone application is not operated and remains off, steps S10 → S11 → S14 → RETURN are repeatedly processed.

  When the automatic button of the smartphone application is operated and turned from off to on, it is processed in steps S10 → S11 → S12 → S13 → RETURN, the automatic button flag is turned on, and the hot water supply / remedy device 2 is activated to fill the hot water. To start.

  In the next cycle, since the automatic button of the smartphone application remains on and the automatic button flag is on, the process is processed in steps S10 → S11 → S14 → S15 → RETURN. The process is repeated until the minimum set hot water amount and energy saving hot water temperature are reached. When it reaches the minimum set amount of hot water and energy-saving hot water, it is processed in steps S15 → S16 → S17 → S18 → RETURN, the hot water filling is completed, notification is made with a display or chime, etc., and the hot water supply / remedy device 2 is put into sleep mode At the same time, the automatic button flag is turned off.

(When a person moves from a place other than the bathroom to the dressing room)
If a person (smartphone 114 linked to the person) is in a place other than the dressing room, steps S20 → S21 → S25 → RETURN are repeatedly performed.

  When a person (smartphone 114 associated with the person) moves to the dressing room 500, steps S20 → S21 → S22 → S23 → S24 → RETURN are processed, the preparation flag is turned on, and the hot water supply / memorial device The sleep mode 2 is canceled, the circulation pump 54 is driven, and the bath temperature sensor 50 detects the hot water temperature and the hot water amount of the bathtub 6.

  After the next cycle, since the person is in the dressing room 500, the smartphone 114 linked to the person is in the dressing room 500, and the preparation flag is on, the process is processed as steps S20 → S21 → S25 → S26. The preparation process is executed. Specifically, steps S20 → S21 → S25 → S26 → S261 → S262 are processed until the bath water temperature and the amount of bath water detected by the bath temperature sensor 50 reach the set values registered in the smartphone 114. Further, until the predetermined time elapses after the smartphone 114 moves to the dressing room 500, S263 → S265 → RETURN is processed following S262, and when the predetermined time elapses, S263 → S264 → S265 → The light of the bathroom 600 is turned on by processing RETURN. When the bath water temperature and the amount of bath water detected by the bath temperature sensor 50 reach the set values registered in the smartphone 114, the process is processed in steps S20 → S21 → S25 → S26 → S261. When the bath water temperature and the bath water amount are adjusted and the bathroom 600 is turned on, the preparation flag is turned off (step S266).

(When a person moves to the bathroom)
If a person is in a place other than the bathroom and the smartphone 114 associated with the person is in a place other than the bathroom, steps S30 → S301 → RETURN are repeated.

  If a person is in the bathroom but not in the bathtub 6, steps S30 → S301 → S302 → S306 → RETURN are repeated.

  If the water level sensor 52 detects that a person has entered the bathtub 6, steps S30 → S301 → S302 → S303 → S304 → S305 → RETURN are processed, and after the next cycle, the person leaves the bathtub 6. Until it tries, step S30-> S301-> S302-> S306-> S307-> S309-> S310-> RETURN is repeated, and the processing in a bathtub is performed. Specifically, if the smartphone 114 is held, steps S310 → S3101 → S3106 → RETURN are processed, and when the smartphone 114 is placed (Yes in step S3101), the display surface of the smartphone 114 faces the wall. If not (No in Step S3102), color gradation illumination is performed with normal illuminance (Step S3103), and if the display surface of the smartphone 114 is directed to the wall (Yes in Step S3102), it is brighter than normal. Color gradation illumination is performed with illuminance (step S3104). Then, music (for example, healing music) is played (step S3105). In this way, it is possible to produce a high-quality bathtub space by performing faint light color gradation lighting in the bathroom and playing healing music. In addition, when the display surface of the smartphone 114 is directed to the wall, the color gradation lighting is performed with a brighter illuminance than usual so that the color gradation lighting spreads like indirect lighting on the wall in a dark bathroom. A space with a mood can be produced.

  If the smartphone 114 is carried without a person trying to get out of the bathtub 6, steps S310 → S3101 → S3106 → S3107 → RETURN are processed, and the color gradation illumination is stopped. If the smartphone 114 is possessed, it can be estimated that there is an intention to use the smartphone 114. Therefore, the color gradation illumination is stopped and the display is returned to the normal display screen. When the smartphone 114 is placed, color gradation illumination is performed again with normal illuminance or illuminance brighter than normal according to the orientation of the smartphone 114 (steps S3103 and S3104).

  When a person tries to get out of the bathtub 6, steps S30 → S301 → S302 → S306 → S307 → S308 → RETURN are processed, and after the next cycle, steps S30 → S301 → S302 → S306 → S307 → S309 → S311 -> RETURN is repeatedly processed, and the bathtub removal process is executed. Specifically, if the smartphone 114 is not carried, the lighting of the bathroom 600 is brightened so that the eyes are not dazzled, and the edge of the bathtub 6 is easily straddled. If the smartphone 114 is possessed, the color gradation lighting is stopped (step S3113), the lighting of the bathroom 600 and the dressing room 500 is returned to the normal state (steps S3114 and S3115), and the music is stopped (step S3116). ), The bathtub entry flag and the bathtub exit flag are turned off (step S3117).

(When the smartphone moves from the bathroom to the dressing room)
If a person (smartphone 114 linked to the person) is in the bathroom, steps S40 → S41 → S44 → RETURN are repeated.

  When a person (smartphone 114 associated with the person) moves from the bathroom 600 to the dressing room 500, the process is performed in steps S40 → S41 → S42 → S43 → RETURN, the bathing end flag is turned on,焚 The device 2 enters the sleep mode.

  After the next cycle, since the smartphone 114 is in the dressing room 500 and the bathing end flag is on, the process is performed in steps S40 → S41 → S44 → S45, and the bathing end process is executed. Specifically, after moving out of the dressing room 500 (Yes in step S451), the bathroom 600 and the dressing room 500 are turned off (step S452).

  As described above, according to the present embodiment, when the switch of any terminal 114 possessed by each person at home is turned on, the amount of hot water is set at each terminal 114 possessed by each person at home. Energy saving calculated based on the lowest hot water temperature among the hot water temperatures and the hot water temperature calculated based on the lowest hot water temperature set for each terminal 114 owned by each person at home. Fill the bath with hot water. Since it did in this way, it can prevent raising hot water temperature unnecessarily and can obtain a high energy-saving effect.

  Further, in the conventional automatic heat insulation, when the hot water filling is completed and there is an interval before the bathing, a renewal is performed in a predetermined time cycle. Therefore, a plurality of chasing operations may be performed before bathing, which wastes energy and is not preferable in terms of energy saving. On the other hand, according to the present embodiment, when the hot water filling is completed, the sleep mode is set, so that the temperature is kept at a hot water temperature slightly lower than the minimum set hot water temperature (for example, a hot water temperature 3 ° C. lower than the minimum set hot water temperature). To save energy and keep warm. Then, when a person (smartphone 114 linked to the person) moves from a place other than the bathroom to the dressing room 500, the sleep mode is canceled to perform the memorial operation. Since it did in this way, it is possible to prevent energy from being wasted by unnecessary chasing operation by the automatic heat retaining function, and to achieve energy saving warming excellent in energy saving effect.

  In addition, when a person (smartphone 114 linked to the person) moves from a place other than the bathroom to the dressing room 500, the hot water state is changed to a person linked to the smartphone 114 moved to the dressing room 500. If it is not set according to the condition, the hot water is adjusted so as to be set according to the person linked to the smartphone 114 moved to the dressing room 500 to adjust the hot water state. I did it. Since it did in this way, it can be in the state of the bath according to each person's liking.

  Furthermore, when a predetermined time has elapsed after a person (smartphone 114 linked to the person) moves from a place other than the bathroom to the dressing room 500, the bathroom 600 is turned on. Since it did in this way, it is convenient that a person does not need to operate the switch of the illumination of the bathroom 600.

  Furthermore, when the person (smartphone 114) who moved to the dressing room 500 further moves to the bathroom 600 and enters the bathtub 6, the lighting of the bathroom 600 is adjusted. That is, instead of dimming when entering the bathroom 600, the lighting is dimmed after entering the bathtub 6. Since it did in this way, when a person straddles the edge of the bathtub 6, it is safe because the illumination is bright, and when a person enters the bathtub 6 across the edge of the bathtub 6, it is relaxed by dimming the illumination of the bathroom 600. An effect is obtained.

  In addition, the lighting of the bathroom 500 is darkened or turned off as the lighting of the bathroom 600 is darkened. Even if the bathroom 600 is darkened, if the washroom 500 is bright, the light of the washroom 500 reaches the bathroom 600. As in the present embodiment, the lighting of the washroom 500 is linked to the lighting of the bathroom 600 to darken the bathroom 600, and when a person enters the bathtub 6, the smartphone 114 in the bathroom is placed. If so, by emitting light from the light emitting surface of the smartphone 114 and performing color gradation illumination, a high-quality bathtub space can be produced, and the relaxation effect is enhanced.

  Furthermore, when the smartphone 114 in the bathroom is placed, if the light emitting surface of the smartphone 114 is away from the wall, light of a predetermined illuminance is emitted from the light emitting surface to perform color gradation illumination, and light emission If the surface is close to the wall, color gradation illumination is performed by emitting light having an illuminance stronger than the predetermined illuminance. In this way, when the light emitting surface is directed to the wall, color gradation lighting is performed with strong light, so in a dark bathroom the color gradation lighting spreads like indirect lighting on the wall and creates a space with a fantasy atmosphere. Can produce.

  Furthermore, music was played along with the color gradation lighting. As a result, a high-quality bathroom space can be produced.

  When the smartphone 114 that performs color gradation illumination is carried, the color gradation illumination is stopped. Since it can be estimated that the smartphone 114 is possessed, it is possible to estimate that there is an intention to use the smartphone 114. Therefore, by stopping the color gradation lighting and returning to the normal display screen, anti-glare can be achieved.

  Moreover, when the person who entered the bathtub 6 is going to get out of the bathtub 6, the illumination of the bathroom 600 was adjusted. Since it did in this way, when a person straddles the edge of the bathtub 6, illumination is bright and safe.

  Furthermore, after determining that the person in the bathtub 6 is about to get out of the bathtub 6, the lighting of the bathroom 600 is so bright that the smartphone 114 that is in the bathroom is brighter than if it is not held. Was adjusted. Thus, anti-glare can be achieved by adjusting the illumination of the bathroom 600 in two stages.

  Further, when adjusting the lighting of the bathroom 600, the lighting of the dressing room 500 is adjusted to make it brighter. Since it does in this way, before a person moves to the dressing room 500, the illumination of the dressing room 500 can be adjusted brightly and it is safe.

  A person (smartphone 114 linked to the person) moves from a place other than the bathroom to the dressing room 500, then moves to the bathroom 600, moves to the dressing room 500 again, and further moves outside the dressing room 500. In this case, the lighting of the bathroom 600 and the dressing room 500 is turned off. By doing so, useless power consumption can be prevented and an energy saving effect can be obtained.

  According to this embodiment, if the bather changes, the brightness of the bathroom and the bathing temperature water level are prepared according to the person, and he / she is healed by music and gradation lighting that each person likes during bathing.

  As described above, according to the present embodiment, a blue tooth function capable of transmitting and receiving dimming intensity is added to the dimming function unit of the bathroom lighting, and pairing is performed using the Proximity Profile (PXP) of the blue tooth function. By using a profile that can determine the distance to the device (dimming function unit), the water level and the bath water temperature are changed according to the bather in advance. It is possible to set a bathing scene that the bather likes most. And if bathing is detected with a pressure sensor, it will change to the brightness of the bathroom most suitable for each person who is going to bathe, and the illumination of the dressing room 500 will be turned off. In addition, it is possible to produce a high-quality bathroom space by performing subtle color gradation lighting in the bathroom 600 and playing healing music. In addition, by temporarily stopping the heat retention function using the location information of the bather, it is possible to prevent memorialization even if it takes time from completion of filling to bathing, and high energy saving An effect can be obtained.

(Second Embodiment)
FIG. 12 is a flowchart showing specific contents of the person whereabouts determination process executed by the bath control apparatus.

  In the following description, parts having the same functions as those described above are denoted by the same reference numerals, and redundant description is omitted as appropriate.

  In the first embodiment, the position of the smartphone 114 is specified by using Bluetooth's Proximity Profile (PXP). However, a GPS (Global Positioning System) may be used. However, GPS signals are difficult to reach indoors, and it is particularly difficult to detect altitude. Therefore, for example, when the bath control device according to the present invention is introduced into an apartment, there is a possibility that the movement to the bathroom 600 or the dressing room 500 in the downstairs / upstairs is erroneously determined as the movement of the own floor. Therefore, when using GPS, after grasping a rough place by GPS, the lighting of the dressing room 500 and the bathroom 600 is blinked with a predetermined illumination pattern. Then, the movement to the dressing room 500 or the bathroom 600 may be determined based on whether or not the illuminance sensor of the smartphone 114 detects the blinking pattern. Specific contents will be described with reference to FIG.

  In step S51, based on the GPS function, it is determined whether the smartphone 114 is in the dressing room 500 (or in the vicinity of the dressing room 500). If the determination result is affirmative, the process proceeds to step S52. If the determination result is negative, the process proceeds to step S55.

  In step S52, the illumination of the dressing room 500 blinks in a predetermined pattern.

  In step S53, it is determined whether or not the detection pattern of the illuminance sensor of the smartphone 114 matches the predetermined pattern in step S52. If the determination result is affirmative, the process proceeds to step S54. If the determination result is negative, the process is temporarily exited.

  In step S <b> 54, it is determined that the smartphone 114 is in the dressing room 500, that is, that a person linked to the smartphone 114 is in the dressing room 500.

  In step S55, based on the GPS function, it is determined whether the smartphone 114 is in the bathroom 600 (or in the vicinity of the bathroom 600). If the determination result is affirmative, the process proceeds to step S56. If the determination result is negative, the process is temporarily exited.

  In step S56, the lighting of the bathroom 600 blinks in a predetermined pattern.

  In step S57, it is determined whether or not the detection pattern of the illuminance sensor of the smartphone 114 matches the predetermined pattern in step S56. If the determination result is affirmative, the process proceeds to step S58, and if the determination result is negative, the process is temporarily exited.

  In step S <b> 58, it is determined that the smartphone 114 is in the bathroom 600, that is, that a person associated with the smartphone 114 is in the bathroom 600.

  Thus, after grasping a rough place by GPS, the lighting of the dressing room 500 and the bathroom 600 blinks with a predetermined illuminance pattern, and whether the blink pattern has been detected by the illuminance sensor of the smartphone 114, the dressing room By determining the movement to 500 or the bathroom 600, the present invention can be implemented even in a terminal (for example, a smartphone) not equipped with Bluetooth Proximity Profile (PXP).

  The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.

  For example, in the above description, a smartphone in which a control application is installed is illustrated as the terminal 114, but a tablet type terminal, a system dedicated terminal, or the like may be used.

  In the color gradation illumination, it is also preferable to control the brightness by an illuminance sensor. This is because antiglare can be achieved in this way.

  Also, bathroom heating (bath warming) may be synchronized. In this case, the timing for starting the bathroom heating (bath warming) is, for example, the timing for starting the hot water filling in step S13, the timing delayed for a predetermined time from the start of the hot water filling, and the smartphone 114 from a place other than the bathroom 600. The timing which moved to the dressing room 500 etc. can be considered. Also, since the time from hot water filling to completion of hot water filling can be predicted, the hot water filling completion timing is predicted, and bathroom heating (bath warming) is started at a predetermined time before that prediction timing. May be. Other timings may also be used. The timing for finishing the bathroom heating (bath warming) is, for example, the completion timing of hot water filling, the timing when the smartphone 114 moves from a place other than the bathroom 600 to the dressing room 500, the timing when the lighting of the bathroom 600 is turned on in step S264, etc. Can be considered. Other timings may also be used.

  Further, the location of the person and the identification of each person may be performed by a face recognition sensor. In this way, the present invention can be implemented without carrying a terminal (for example, a smartphone) during bathing.

  The above embodiments can be appropriately combined.
