Determine if the temperature has risen to the temperature condition. Then, when the temperature condition is satisfied, the control unit 211 starts the operation of the heat source related function.

FIG. 3 is a diagram showing the configuration of the bathroom air conditioner 20. In FIG. 1, the heating / drying unit 230 and the ventilation unit 240 are in a state in which the housings 230a and 240a are shown in cross section and the inside is seen through.

As shown in FIG. 3, the bathroom air conditioner 21 includes a heating / drying unit 230 and a ventilation unit 240. The heating / drying unit 230 and the ventilation unit 240 are integrated with each other.

The heating / drying unit 230 includes a suction port 231 for sucking air and a discharge port 232 for discharging air in the lower part of the housing 230a. The suction port 231 and the discharge port 232 are each exposed from the ceiling of the bathroom into the bathroom. The discharge port 232 is provided with a louver (not shown) for changing the air discharge direction. The louver is driven by a motor. Inside the housing 230a, an air flow path P1 is formed between the suction port 231 and the discharge port 232. A heat exchanger 233 and a blower 234 are arranged in the flow path P1.

The heat exchanger 233 warms the air passing through the heat exchanger 233 with the hot water supplied from the water heater 11 which is a heat source. The outbound pipe 14a and the inbound pipe 14b are connected to the heat exchanger 233. When the heating function and the drying function are executed, the hot water heated by the burner or the like in the water heater 11 circulates in the heat exchanger 233 via the pipes 14a and 14b. This warms the air passing through the heat exchanger 233.

The blower 234 blows air from the suction port 231 toward the discharge port 232 so that the air flows through the flow path P1. The blower 234 is, for example, a cross-flow fan, which is driven by a motor (not shown).

A thermistor 235 for detecting the temperature of hot water flowing through the pipe 14a is arranged in the pipe 14a. The thermistor 235 is included in the detection unit 214 of FIG. Further, a thermal valve (not shown) for controlling the flow of hot water is arranged in the pipe 14a. When the thermal valve is opened, hot water flows through the pipes 14a and 14b, and the hot water circulates between the water heater 11 and the heat exchanger 233.

The ventilation unit 240 includes a suction port 241 for sucking air and a discharge port 242 for discharging air in the housing 240a. The suction port 241 is connected to the bathroom. The discharge port 242 is connected to the outside via a duct. In FIG. 3, only one suction port 241 is provided in the housing 240a, but another suction port may be provided in the housing 240a. This suction port is connected to a room other than the bathroom (for example, a dressing room) via a duct.

Inside the housing 240a, an air flow path P2 is configured between the suction port 241 and the discharge port 242. A blower 243 is arranged in the flow path P2. The blower 243 is, for example, a sirocco fan, which is driven by a motor (not shown).

When the heating function and the drying function are executed, the air in the bathroom taken in from the suction port 231 is discharged from the exhaust port 232 into the bathroom through the heat exchanger 233 by the air blown by the blower 234. As the air passes through the heat exchanger 233, the air is warmed and dehumidified. After that, the air is discharged into the bathroom from the discharge port 232, so that the inside of the bathroom is heated and dried. In this way, the bathroom is heated and dried.

When the ventilation function is executed, the air taken in from the suction port 241 is discharged to the outside from the discharge port 242 through the flow path P2 by the air blown by the blower 243. As a result, the bathroom and the like are ventilated.

When the blower function is executed, the blower 234 is driven without passing hot water through the heat exchanger 233. As a result, the air in the bathroom taken in from the suction port 231 passes through the heat exchanger 233 and is discharged into the bathroom from the discharge port 232. In this case, the air flowing through the flow path P1 is not warmed by the heat exchanger 233. Therefore, air having the same temperature as in the bathroom is discharged into the bathroom from the discharge port 232.

When the heating function and the drying function (heat source related function) are executed, the heat valve of the pipe 14a is opened, the water heater 11 which is a heat source is driven, and hot water is supplied to the heat exchanger 233. At this stage, the blower 234 is not driven, and air is not yet discharged from the discharge port 232. After that, the temperature of the hot water flowing through the heat exchanger 233 is monitored by the thermistor 235, and the blower 234 is driven when the temperature detected by the thermistor 235 reaches a target temperature suitable for the heating function and the drying function. As a result, the air warmed by the heat exchanger 233 is discharged from the discharge port 232. After that, the water heater 11 is controlled so that the temperature of the thermistor 235 becomes the target temperature.

It takes several minutes (for example, 1 to 3 minutes) for the temperature of the hot water flowing through the heat exchanger 233 to reach the target temperature. That is, there is a time lag of several minutes between the start of the hot water supply operation for the heat exchanger 233 and the actual start of the operation of the heating function and the drying function. This time lag varies depending on the environmental temperature, the lengths of the pipes 14a and 14b, and the like.

Control boards 236 and 244 are installed in the heating / drying unit 230 and the ventilation unit 240, respectively. These control boards 236 and 244 include the control unit 211, the storage unit 212, and the communication unit 213 of FIG. The bathroom air-conditioning remote controller 22 is communicably connected to the control board 236 on the heating / drying unit 230 side. Further, the control boards 236 and 244 are connected to each other so as to be able to communicate with each other. The control board 236 is arranged with a circuit unit for driving and controlling the heating / drying unit 230 and the water heater 11, and the control board 244 is arranged with a circuit unit for driving and controlling the ventilation unit 240. ..

When the control board 236 receives a signal from the bathroom air-conditioning remote controller 22 in response to an operation input to the input unit 222 of the bathroom air-conditioning remote controller 22, the control board 236 executes control according to the received signal. For example, when the received signal is a signal relating to a heating function or a drying function, the control board 236 controls the water heater 11 and the heating / drying unit 230. For example, as this control, the control board 236 controls the blower 234, the burner in the water heater 11, and the louver installed in the discharge port 232.

When the signal received from the bathroom air-conditioning remote controller 22 is a signal related to the ventilation function, the control board 236 transfers this signal to the control board 244. As a result, ventilation control based on the signal is performed on the control board 244. In this control, the blower 243 is driven.

Further, when the signal received from the bathroom air-conditioning remote controller 22 is a signal related to the blower function, the control board 236 simply controls to drive the blower 234. In this case, the control board 236 does not control the water heater 11. As a result, the air in the bathroom taken in from the suction port 231 is discharged into the bathroom from the discharge port 232 without being warmed.

When remote control is performed using the mobile terminal device 40, execution instructions for each function of heating, drying, ventilation, and ventilation are transferred from the kitchen remote controller 13 to the control unit 111 of the water heater 11, and further, the control unit. It is transferred from 111 to the control board 236. As a result, the heating, drying, ventilation and ventilation functions are executed under the control of the control board 236 as described above.

Returning to FIG. 2, the mobile terminal device 40 includes a display unit 401, an input unit 402, a control unit 403, a storage unit 404, and a wireless communication unit 405. The display unit 401 is composed of, for example, a liquid crystal panel. The input unit 132 includes various operation buttons and a touch panel laminated on the display unit 401.

The control unit 403 includes a CPU (Central Processing Unit) and performs predetermined control according to a program stored in the storage unit 404. The storage unit 404 includes a memory and stores a predetermined control program. The wireless communication unit 405 communicates with the router 30 according to the control from the control unit 403. The wireless communication unit 405 is a wireless communication module capable of wireless communication with the router 30. An IP address is also assigned to the wireless communication unit 405. Further, the wireless communication unit 405 holds the above-mentioned MAC address. In addition, the mobile terminal device 40 includes a speaker for outputting audio.

The server 60 includes a control unit 601, a storage unit 602, and a communication unit 603. The control unit 601 includes a CPU and performs predetermined control according to a program stored in the storage unit 602. The storage unit 602 includes a memory and a hard disk, and stores a predetermined control program and database. The communication unit 603 performs predetermined control according to the control from the control unit 601.

In the first embodiment, the portable terminal device 40 capable of remotely controlling the hot water supply device 10 is registered in the server 60 in advance in association with the hot water supply device 10. That is, the hot water supply device 10 and the mobile terminal device 40 are paired in advance, and information indicating pairing (pairing information) is managed by the server 60. Specifically, the ID information of the hot water supply device 10 and the ID information of the mobile terminal device 40 are associated with each other to form pairing information. Such pairing is performed, for example, in the home H10 in which the hot water supply device 10 is installed. This reduces the possibility that the mobile terminal device 40 and the hot water supply device 10 are unfairly paired by a malicious third party.

Here, the number of mobile terminal devices 40 that can be paired with one hot water supply device 10 is not limited to one. It can be assumed that a plurality of users, such as family members, each perform pairing between the portable terminal device 40 owned by the user and the hot water supply device 10. As a result, each member of the family can remotely control the hot water supply device 10 and the bathroom air conditioner 20 by their own mobile terminal device 40 outside the home.

In this way, when the user remotely controls the mobile terminal device 40 outside the home, for example, when the user in the home H10 is taking a bath, the user outside the home remotely controls the mobile terminal device 40. As a result of the above, it is possible that the bathroom air-conditioning function such as heating and drying of the bathroom is executed. In this case, the air-conditioning condition in the bathroom changes unexpectedly, which causes a remarkable discomfort to the user while taking a bath. In this way, when the bathroom air-conditioning function is executed by remotely controlling the mobile terminal device 40 without the user outside the house grasping the usage state of the bathroom, the user who is taking a bath is uncomfortable. There is a risk that it will end up.

Therefore, in the first embodiment, in order to suppress such a situation, the execution of the bathroom air conditioning function by remote control is restricted when the user is taking a bath. This configuration will be described below.

The bathroom air conditioning function limited here may include at least one of the above-mentioned heating, drying, ventilation and ventilation functions. All of these functions may be restricted, and only the bathroom air conditioning function, which is particularly likely to cause discomfort to the bather, may be restricted. Alternatively, bathroom air conditioning functions other than these functions may be further restricted. In the following, the server 60 controls during remote control, assuming that all of the above-mentioned heating, drying, ventilation, and ventilation functions are included in the functions that can be restricted during remote control.

FIG. 4 is a flowchart showing a process performed by the control unit 211 of the bathroom air conditioner 21 when the user inputs a remote control to the mobile terminal device 40. Further, FIG. 5A is a flowchart showing a process performed by the control unit 403 of the mobile terminal device 40 when the user inputs a remote control to the mobile terminal device 40. At the time of processing of FIGS. 4 and 5A, the user has started the application program of the hot water supply system 1 installed in the mobile terminal device 40, and the server 60 is in a state of being able to communicate with the mobile terminal device 40. Is.

With reference to FIG. 5A, when the control unit 403 of the mobile terminal device 40 receives an operation from the user for the input unit 402 (S201: YES), the control unit 403 is for executing the remote control corresponding to this operation. The command notification is transmitted to the server 60 (S202). At this time, the control unit 403 transmits the ID information of the mobile terminal device 40 together with the command notification.

When the control unit 601 of the server 60 receives the command notification regarding remote control from the control unit 403 of the mobile terminal device 40, the control unit 601 transmits the command notification to the kitchen remote controller 13 associated with the ID information included in the command notification. To do. When the received command notification is not related to the bathroom air conditioning function, the control unit 133 of the kitchen remote controller 13 executes an operation corresponding to the command notification. On the other hand, when the received command notification is related to the bathroom air conditioning function, the control unit 133 of the kitchen remote controller 13 transmits the received command notification to the control unit 211 of the bathroom air conditioner 21 via the control unit 111 of the water heater 11. To do.

With reference to FIG. 4, when the control unit 211 of the bathroom air conditioner 21 receives the command notification from the control unit 111 of the water heater 11 (S101: YES), the control unit 211 refers to the status information updated at any time, and a person is in the bathroom. It is determined whether or not there is a bathroom (S102). Specifically, the control unit 211 determines whether or not there is a person in the bathroom by referring to the detection result of the motion sensor 126 included in the state information.

When there is a person in the bathroom (S102: YES), the control unit 211 transmits the refusal notification to the control unit 111 of the water heater 11 without executing the operation of the received command notification (S103). The transmitted refusal notification is transmitted from the control unit 111 of the water heater 11 to the server 60 via the kitchen remote controller 13. At this time, the control unit 133 of the kitchen remote controller 13 transmits its own ID information to the server 60 together with the refusal notification. The control unit 601 of the server 60 identifies the mobile terminal device 40 that has been remotely controlled by referring to the received ID information, and transmits a refusal notification as a response notification to the specified mobile terminal device 40.

When there is no person in the bathroom (S102: NO), the control unit 211 transmits an execution notification to the control unit 111 of the water heater 11 (S104). The execution notification is transmitted as a response notification to the mobile terminal device 40 that has been remotely controlled by the same process as described above. Further, the control unit 211 determines whether or not the content of the received command notification is related to the heat source related function (S105). As described above, the heat source-related function is a bathroom air conditioning function performed by using the heat supplied from the heat source (water heater 11). Here, the heating and drying functions for the bathroom correspond to the heat source related functions.

When the content of the command notification is not related to the heat source related function (S105: NO), that is, when the content of the command notification is related to ventilation or ventilation to the bathroom, the control unit 211 provides the bathroom air conditioning function corresponding to the command notification. Execute (S106). In response to this, the blower 234 of the heating / drying unit 230 or the blower 243 of the ventilation unit 240 is driven to blow or ventilate the bathroom.

On the other hand, when the content of the command notification is related to the heat source related function (S105: YES), that is, when the content of the command notification is related to heating or drying the bathroom, the control unit 211 is arranged in the pipe 14a. The heat valve is opened and the water heater 11 is driven to execute the hot water supply operation for the heat exchanger 233 (S107). After that, the control unit 211 monitors whether or not the start condition of the heat source-related function corresponding to the command notification is satisfied (S108). Specifically, the control unit 211 detects the temperature of the hot water supplied to the heat exchanger 233 based on the output of the thermistor 235 arranged in the pipe 14a, and the temperature of the hot water is the heat source corresponding to the command notification. Determine if the target temperature suitable for the relevant function has been reached.

When the start condition of the heat source-related function is satisfied, the control unit 211 again refers to the latest state information and determines whether or not there is a person in the bathroom (S109). The determination method in step S109 is the same as in step S102. When there is no person in the bathroom (S109: NO), the control unit 211 drives the blower 234 of the heating / drying unit 230 (S110). As a result, the air warmed by the heat exchanger 233 is sent into the bathroom from the discharge port 232, and the inside of the bathroom is heated or dried.

On the other hand, when there is a person in the bathroom (S109: YES), the control unit 211 stops executing the heat source related function without driving the blower 234 of the heating / drying unit 230 (S111). Specifically, the control unit 211 closes the thermal valve arranged in the pipe 14a and stops the water heater 11. Then, the control unit 211 transmits an execution stop notification indicating that the execution of the bathroom air conditioning function (heat source related function) corresponding to the command notification has been stopped to the control unit 111 of the water heater 11. This notification is transmitted to the mobile terminal device 40, which is the transmission source of the command notification, by the same processing as the response notification. As a result, the control unit 211 ends the process.

With reference to FIG. 5A, when the control unit 403 of the mobile terminal device 40 receives the response notification from the server 60 (S203: YES), it is determined whether the response notification is a rejection notification or an execution notification. Judgment (S204). When the received response notification is a rejection notification (S204: YES), the control unit 403 causes the display unit 401 to display the rejection screen (S205). On the other hand, when the received response notification is an execution notification (S204: NO), the control unit 403 causes the display unit 401 to display the execution screen (S206).

6 (a) and 6 (b) are diagrams showing screens displayed on the display unit 401 of the mobile terminal device 40 in response to the reception of the response notification, respectively. FIG. 6A shows a display example of the rejection screen P10, and FIG. 6B shows a display example of the execution screen P20.

As shown in FIG. 6A, the refusal screen P10 includes an item P11 indicating the content of the remote control, a message P12 indicating that the remote control has been rejected, and an approval button P13. Further, as shown in FIG. 6B, the execution screen P20 includes an item P21 indicating the content of the remote control, a message P22 indicating that the remote operation has been executed, and an approval button P23. ..

By referring to the item P11 and the message P12 on the refusal screen P10, the user can grasp that the remote control of the bathroom air-conditioning function performed by the user has been refused. Further, the user can grasp that the remote control of the bathroom air-conditioning function performed by himself / herself has been executed by referring to the item P21 and the message P22 on the execution screen P20. After referring to the messages P12 and P22, the user operates the approval buttons P13 and P23. As a result, the refusal screen P10 and the execution screen P20 are closed, and the screen before these screens are displayed is displayed.

In addition, although the cases where the contents of the remote control are ventilation and heating for the bathroom are exemplified in FIGS. 6 (a) and 6 (b), other bathroom air-conditioning functions such as bathroom drying are the targets of the remote control. If so, a similar screen is displayed. In this case, the contents of items P11 and P21 are changed to other bathroom air conditioning functions such as bathroom drying.

FIG. 5B is a flowchart showing a process executed by the control unit 403 of the mobile terminal device 40 after displaying the execution screen P20 on the display unit 401. This process is performed when the content of the remote control is a heat source related function.

After displaying the execution screen P20 in step S206 of FIG. 5A, the control unit 403 of the mobile terminal device 40 determines whether or not the execution stop notification has been received from the server 60 within a predetermined time (S211). (S212). The predetermined time in step S211 is set to be slightly longer than the longest time that can be assumed as the time from the start of the hot water supply operation in step S107 of FIG. 4 to the satisfaction of the start condition in step S108.

If the execution stop notification is not received from the server 60 within the predetermined time (S211: YES, S211: NO), the control unit 403 ends the process without performing the process in step S213. On the other hand, when the execution stop notification is received from the server 60 within the predetermined time (S211: NO, S211: YES), the control unit 403 causes the display unit 401 to display the execution stop screen (S213), and ends the process. ..

FIG. 6C is a diagram showing an execution stop screen P30 displayed on the display unit 401 of the mobile terminal device 40 in response to the reception of the execution stop notification.

As shown in FIG. 6C, the execution stop screen P30 includes an item P31 indicating the content of the remote control, a message P32 indicating that the execution of the remote control has been stopped, and an approval button P33. There is. By referring to the item P31 and the message P32 on the execution stop screen P30, the user can grasp that the execution of the remote control of the bathroom air conditioning function (heat source related function) performed by the user has been stopped. After referring to the message P32, the user operates the approval button P33. As a result, the execution stop screen P30 is closed, and the screen before this screen is displayed is displayed.

In addition, although the case where the content of the remote control is the bathroom heating is illustrated in FIG. 6C, the same screen is displayed even when the bathroom drying (other heat source related functions) is the target of the remote control. Will be done. In this case, the content of item P31 is changed to bathroom drying.

<Effect of Embodiment 1>
According to the first embodiment, the following effects can be achieved.

When there is a person in the bathroom, the remote control of the predetermined bathroom air-conditioning function by the portable terminal device 40 is suppressed by the bathroom air-conditioning device 20 (control unit 211 of the bathroom air-conditioner 21). As a result, it is possible to prevent the bathroom air-conditioning function such as ventilation and heating from being suddenly executed by remote control in a situation where the user in the house is taking a bath. Therefore, it is possible to appropriately prevent the user from being uncomfortable while taking a bath.

Further, the bathroom air-conditioning function restricted when there is a person in the bathroom includes a heat source-related function (bathroom heating, bathroom drying) using heat from the water heater 11 (heat source). As a result, it is possible to prevent the temperature in the bathroom from suddenly rising by remote control when the user in the house is taking a bath. Therefore, it is possible to appropriately prevent the user who is taking a bath from being uncomfortable due to the temperature rise.

Further, as shown in FIG. 4, the control unit 211 of the bathroom air conditioner 21 is based on the heat from the water heater 11 (heat source) after receiving the operation start instruction of the heat source related functions (bathroom heating, bathroom drying). When the operation start condition of the heat source related function is satisfied (S108: YES), when a person is detected by the motion sensor 126 (human detection sensor) (S109: YES), the heat source related function corresponding to the operation start instruction. (S111), the start of the operation is suppressed. As a result, even if there is no person in the bathroom at the timing when the operation start instruction is received, if there is a person in the bathroom when the operation of the heat source related function can be started, the start of the operation is suppressed. Therefore, it is possible to appropriately prevent the user who is taking a bath from being uncomfortable due to the temperature rise. Further, if there is no person in the bathroom at the time when the operation of the heat source-related function can be started, the operation can be started smoothly and promptly.

Further, as shown in FIG. 4, when the control unit 211 of the bathroom air conditioner 21 suppresses the start of the operation corresponding to the operation start instruction (S102: YES, S111), the mobile terminal device 40 is notified to that effect. (S103, S112). As a result, in the mobile terminal device 40, it is possible to perform a process of notifying the user of the mobile terminal device 40, together with the information that the user is currently taking a bath, that the execution of remote control has been suppressed. For example, the control unit 403 of the mobile terminal device 40 causes the display unit 401 to display the rejection screen P10 shown in FIG. 6A or the execution stop screen P30 shown in FIG. 6C in response to these notifications. As a result, the user of the mobile terminal device 40 can grasp that the operation of his / her remote control has been suppressed together with the reason, and can take appropriate measures thereafter.

<Example of modification of Embodiment 1>
In the first embodiment, when there is a person in the bathroom when the bathroom air-conditioning function based on remote control is executed, the execution of the bathroom air-conditioning function is suppressed. On the other hand, in this modified example, if there is a person in the bathroom when the bathroom air-conditioning function based on remote control is executed, the execution of the bathroom air-conditioning function is suspended, and then the person leaves the bathroom. The bathroom air conditioning function is executed.

FIG. 7 is a flowchart showing a process performed by the control unit 211 of the bathroom air conditioner 21 when the user inputs a remote control to the mobile terminal device 40 according to the modification example.

In the flowchart of FIG. 7, steps S103 of the flowchart of FIG. 4 are replaced with steps S121 to S123, and steps S111 and S112 of the flowchart of FIG. 4 are replaced with steps S124 and S125. The other steps of FIG. 7 are similar to the corresponding steps of FIG.

With reference to FIG. 7, when the control unit 211 of the bathroom air conditioner 21 receives the command notification from the control unit 111 of the water heater 11 (S101: YES), determines that there is a person in the bathroom (S102: YES), a hold notification indicating that the execution of the bathroom air conditioning function corresponding to the command notification is suspended is transmitted to the control unit 111 of the water heater 11 as a response notification (S121). This notification is transmitted to the mobile terminal device 40, which is the transmission source of the command notification, by the same processing as the refusal notification transmitted in step S103 of FIG.

After that, the control unit 211 of the bathroom air conditioner 21 determines whether or not a person has left the bathroom with reference to the status information updated at any time (S122). Here, when the detection result of the motion sensor 126 included in the state information indicates that there is no person continuously for a predetermined time (for example, 1 minute), it is determined that the person has left the bathroom. When the control unit 211 determines that a person has left the bathroom (S122: YES), the control unit 211 transmits a hold release notification indicating that the hold of the bathroom air conditioning function has been released to the control unit 111 of the water heater 11 (S123). This notification is transmitted to the mobile terminal device 40, which is the transmission source of the command notification, by the same processing as described above.

After that, the control unit 211 advances the process to step S105. The processing of steps S105 to S109 and step S110 is the same as the corresponding step of FIG.

If it is determined in step S109 that there is a person in the bathroom (S109: YES), the control unit 211 temporarily stops the hot water supply operation for the heat exchanger 233 that started execution in step S107 (S124), and then from the bathroom. It is determined whether or not a person has left the room (S125). The determination in step S125 is the same as in step S122. Then, when a person leaves the bathroom (S125: YES), the control unit 211 returns the process to step S107 and starts the hot water supply operation to the heat exchanger 233 again.

In this way, the control unit 211 processes steps S107 to S109 and steps S124 and S125 until the start condition is satisfied (S108: YES) and the absence of people in the bathroom is satisfied (S109: YES). repeat. Then, when the start condition is satisfied (S108: YES), when there is no person in the bathroom (S109: YES), the control unit 211 drives the blower 234 of the heating / drying unit 230 to notify the command. The operation of the corresponding heat source related function is started (S110). As a result, the air warmed by the heat exchanger 233 is sent into the bathroom from the discharge port 232, and the inside of the bathroom is heated or dried. In this way, the control unit 211 ends the process.

In the flowchart of FIG. 7, instead of the refusal notification, the hold notification (S121) and the hold release notification (S123) are transmitted. When the hold notification is received, the control unit 403 of the mobile terminal device 40 causes the display unit 401 to display the hold screen P40 shown in FIG. 8A. Further, when the hold release notification is received after that, the control unit 403 of the mobile terminal device 40 causes the display unit 401 to display the hold release screen P50 shown in FIG. 8B.

<Embodiment 2>
In the first embodiment, the control unit 211 of the bathroom air conditioner 21 determines whether or not to suppress the execution of the bathroom air conditioning function, but in the second embodiment, a part of this determination is the control unit of the server 60. This is performed in the control unit 403 of 601 or the portable terminal device 40.

FIG. 9A is a flowchart showing a process when the control unit 601 of the server 60 performs a part of the determination as to whether or not to suppress the execution of the bathroom air conditioning function. Further, FIG. 9B is a flowchart showing a process when the control unit 403 of the mobile terminal device 40 performs a part of the determination as to whether or not to suppress the execution of the bathroom air conditioning function.

First, referring to FIG. 9A, when the control unit 601 of the server 60 receives the command notification from the mobile terminal device 40 (S301: YES), whether or not the content of the command notification is related to the bathroom air conditioning function. (S302). When the content of the command notification is not related to the bathroom air conditioning function (S302: NO), the control unit 601 transmits an execution notification to the mobile terminal device 40 that has transmitted the command notification (S305), and further to the mobile terminal device 40. The command notification is transferred to the associated kitchen remote controller 13 (S306). As a result, the kitchen remote controller 13 executes an operation corresponding to the command notification.

On the other hand, when the content of the command notification relates to the bathroom air conditioning function (S302: YES), the control unit 601 of the hot water supply device 10 (kitchen remote controller 13) associated with the mobile terminal device 40 that transmitted the command notification. With reference to the state information, it is determined whether or not there is a person in the bathroom (S303). Here, as in step S102 of FIG. 4, the presence or absence of a person in the bathroom is determined based on the detection result of the motion sensor 126 included in the state information.

When there is no person in the bathroom (S303: NO), the control unit 601 transmits an execution notification to the mobile terminal device 40 from which the command notification is transmitted (S305). As a result, the execution screen P20 similar to that shown in FIG. 6B is displayed on the display unit 401 of the mobile terminal device 40. Further, the control unit 601 transmits a command notification to the hot water supply device 10 (kitchen remote controller 13) associated with the mobile terminal device 40 (S306).

When the content of the remote control is not related to the bathroom air conditioning function (S222: NO), the control unit 403 displays the execution screen P20 on the mobile terminal device 40 that has transmitted the execution screen command notification similar to that in FIG. 6 (b). It is displayed on 401 (S225), and a command notification corresponding to remote control is transmitted to the server 60 together with its own ID information (S225). As a result, the hot water supply device 10 associated with the mobile terminal device 40 executes an operation corresponding to remote control.

On the other hand, when the content of the remote control is related to the bathroom air-conditioning function (S222: YES), the control unit 403 acquires the state information of the controlled hot water supply device 10 (kitchen remote controller 13) from the server 60, and the acquired state. With reference to the information, it is determined whether or not there is a person in the bathroom (S223). Here, as in step S102 of FIG. 4, the presence or absence of a person in the bathroom is determined based on the detection result of the motion sensor 126 included in the state information.

When there is no person in the bathroom (S223: NO), the control unit 403 displays the execution screen P20 on the display unit 401 (S225), and further sends a command notification corresponding to the remote control to the server 60 together with its own ID information. Transmit (S226). The server 60 transmits the received command notification to the kitchen remote controller 13 associated with the ID information. In this case, since the received command notification is related to the bathroom air conditioning function, the control unit 133 of the kitchen remote controller 13 sends the command notification to the control unit 211 of the bathroom air conditioner 21 via the control unit 111 of the water heater 11. Send.

On the other hand, when there is a person in the bathroom (S223: YES), the control unit 403 causes the display unit 401 to display the rejection screen P10 (S225). In this case, the control unit 403 ends the process without transmitting the command notification to the server 60. Therefore, the bathroom air-conditioning device 20 at the control destination does not execute the bathroom air-conditioning function corresponding to the command notification.

FIG. 10 is a flowchart showing a process performed by the control unit 211 of the bathroom air conditioner 21 when a command notification regarding the bathroom air conditioning function is transmitted by the process of FIG. 9A or FIG. 9B.
