  In step S <b> 12, control unit 205 of hot water supply apparatus 210 transmits a command of content for performing temperature change notification to bathroom remote controller 310 and kitchen remote controller 320. The bathroom remote controller 310 and the kitchen remote controller 320 that have received the command execute a temperature change notification. That is, in the audio output unit 303 of the bathroom remote controller 310 and the kitchen remote controller 320, the set value of the hot water supply temperature is changed from the second set temperature for the dishwasher 220 to the normal set temperature, that is, the first set temperature. A voice message with the content to notify is output from the speaker. After step S12, the process of this routine is terminated.

  In the present embodiment, the following effects can be obtained. When the hot water temperature setting value is automatically changed from a relatively low first setting temperature to a relatively high second setting temperature, after the user is informed in advance of the setting temperature change, the hot water temperature setting value is changed. Change from the first set temperature to the second set temperature. Conversely, when the hot water temperature setting value is automatically changed from the relatively high second setting temperature to the relatively low first setting temperature, the hot water temperature setting value is first changed from the first setting temperature to the second setting temperature. Change to temperature, and then notify the user of the change in set temperature. Thereby, it can suppress more reliably that the hot water of the temperature which a user does not intend is discharged from the 1st hot-water tap 10 or the 2nd hot-water tap 20.

  In the present embodiment, the configuration in which hot water supply apparatus 210 and dish washing apparatus 220 communicate via HEMS controller 100 has been described as an example. Not only such a configuration but also a configuration in which the hot water supply device 210 and the tableware washing device 220 communicate via devices other than the HEMS controller 100, or a configuration in which the hot water supply device 210 and the tableware washing device 220 directly communicate with each other. But you can.

Embodiment 2. FIG.
Next, the second embodiment will be described. The difference from the first embodiment will be mainly described, and the description of the same or corresponding parts will be simplified or omitted. The configuration of the hot water supply system 1 according to the second embodiment may be the same as the configuration of FIGS. 1 and 2.

  The bathroom remote control 310 includes a human sensor 307 that detects the presence or absence of a person in the bathroom 910. The human sensor 307 of the bathroom remote control 310 is an example of a unit that acquires information about the presence of the person in the place where the first hot-water tap 10 is located, that is, the bathroom 910. The kitchen remote controller 320 includes a human sensor 307 that detects the presence or absence of a person in the kitchen 920. The human sensor 307 of the kitchen remote controller 320 is an example of a unit that acquires information on the presence of the person in the place where the second hot-water tap 20 is located, that is, the kitchen 920.

  The hot water supply system 1 of the second embodiment executes the control routine of FIG. 3 described above, but differs in the following points. In the second embodiment, the following is performed in step S2 of FIG. When the presence sensor 307 of the bathroom remote controller 310 detects that there is no person in the bathroom 910, the bathroom remote controller 310 does not execute a temperature change notice by voice from the voice output unit 303. When the presence sensor 307 of the kitchen remote controller 320 detects that there is no person in the kitchen 920, the kitchen remote controller 320 does not execute a temperature change notice by voice from the voice output unit 303. When the presence sensor 307 of the bathroom remote controller 310 detects that there is a person in the bathroom 910, the bathroom remote controller 310 executes a temperature change notice by voice from the voice output unit 303. When the presence of a person in the kitchen 920 is detected by the human sensor 307 of the kitchen remote controller 320, the kitchen remote controller 320 executes a temperature change notice by voice from the voice output unit 303.

  According to the second embodiment, the following effects can be obtained. When there is no person in the bathroom 910, there is a low possibility that the first hot-water tap 10 will take out the hot water, so that the need for the bathroom remote controller 310 to make a sound temperature change notice is low. In this case, it is possible to prevent the user from feeling uncomfortable by unnecessary voice guidance by not performing the temperature change notice by voice. When there is no person in the kitchen 920, there is a low possibility that the second hot-water tap 20 will discharge the hot water, so that it is less necessary for the kitchen remote controller 320 to make a sound temperature change notice. In this case, it is possible to prevent the user from feeling uncomfortable by unnecessary voice guidance by not performing the temperature change notice by voice.

  As a modification of the present embodiment, information on the presence or absence of a person in a place where the first hot-water tap 10 or the second hot-water tap 20 is obtained by means other than the human sensor 307 provided in the bathroom remote control 310 or the kitchen remote control 320. May be. For example, the following may be used. When a human sensor is built in a room air conditioner installed in the dining kitchen, the human sensor detects the presence or absence of a person in the kitchen 920. The control unit 205 of the hot water supply apparatus 210 may acquire the detected information via the HEMS controller 100. In this way, information detected by another electrical device 200 equipped with a human sensor may be used.

Embodiment 3 FIG.
Next, the third embodiment will be described with reference to FIG. 4. The description will focus on the differences from the above-described embodiment, and the description of the same or corresponding parts will be simplified or omitted. The configuration of hot water supply system 1 of the third embodiment may be the same as the configuration of FIGS. 1 and 2.

  The state of at least one electric device 200 in the place where the first hot-water tap 10 or the second hot-water tap 20 is located is referred to as a “neighboring device state” in this specification. In the third embodiment, the following is performed. The control unit 205 of the hot water supply apparatus 210 can acquire information related to the neighboring device state in real time via the HEMS controller 100.

  The hot water supply system 1 of the third embodiment executes the control routine of FIG. 3 described above, but differs in the following points. In step S2 of FIG. 3, the following is performed. When the location where the first hot-water tap 10 is located, that is, the state of the current neighboring device with respect to the bathroom 910 corresponds to the first pattern in which there is a high possibility that there is a person in the bathroom 910, the bathroom remote controller 310 outputs audio. A temperature change notice is executed by voice from the unit 303. When the current neighboring device state of the bathroom 910 corresponds to the second pattern in which it is considered that there is a low possibility that there is a person in the bathroom 910, the bathroom remote controller 310 notifies the temperature change notice by sound from the sound output unit 303. Do not execute. When the location where the second hot-water tap 20 is located, that is, the current state of the neighboring device about the kitchen 920 corresponds to the first pattern that can be considered that there is a high possibility that there is a person in the kitchen 920, the kitchen remote controller 320 outputs audio. A temperature change notice is executed by voice from the unit 303. When the current neighboring device state of the kitchen 920 corresponds to the second pattern in which it is considered that there is a low possibility that there is a person in the kitchen 920, the kitchen remote controller 320 notifies the temperature change by voice from the voice output unit 303. Do not execute.

  If it is this Embodiment 3, the effect similar to Embodiment 2 will be acquired. That is, the following effects can be obtained. In the case where the current neighboring device state of the bathroom 910 corresponds to the second pattern in which it is considered that there is a low possibility that there is a person in the bathroom 910, that is, when there is a low possibility that there is a person in the bathroom 910, Since there is a low possibility that the hot water will be discharged from the bathroom 10, it is less necessary for the bathroom remote controller 310 to perform a temperature change notice by voice. In this case, it is possible to prevent the user from feeling uncomfortable by unnecessary voice guidance by not performing the temperature change notice by voice. When the current neighboring device state of the kitchen 920 corresponds to the second pattern in which it is considered that there is a low possibility that there is a person in the kitchen 920, that is, when the possibility that there is a person in the kitchen 920 is low, the second hot water tap Since there is a low possibility that the hot water will be discharged from 20, the necessity for the kitchen remote controller 320 to give a temperature change notice by voice is low. In this case, it is possible to prevent the user from feeling uncomfortable by unnecessary voice guidance by not performing the temperature change notice by voice. According to the third embodiment, even when the bathroom remote controller 310 and the kitchen remote controller 320 are not provided with the human sensor 307, the above-described effect can be obtained, so that the cost can be reduced.

  As the neighboring device state for the bathroom 910, for example, the lighting and extinguishing states of the bathroom lighting 230 may be used. In this case, the state in which the bathroom lighting 230 is lit may be the first pattern that can be considered as a high possibility that there is a person in the bathroom 910. The state in which the bathroom lighting 230 is turned off may be a second pattern that can be regarded as a low possibility that there is a person in the bathroom 910.

  For example, the state of operation and stop of a bathroom dryer or a bathroom ventilation fan may be used as the neighboring device state for the bathroom 910. For example, the state in which the bathroom dryer is operating may be a second pattern that can be regarded as a low possibility that there is a person in the bathroom 910.

  A combination of the states of the plurality of electric devices 200 may be used as the neighboring device state. For example, a combination of the lighting and extinguishing states of the bathroom lighting 230 and the operating and stopping states of the bathroom ventilation fan may be used as the neighboring device state. Even when the bathroom lighting 230 is turned off, it can be considered as follows when the bathroom ventilation fan is operating. Since the interior of the bathroom 910 is bright due to sunlight from the window of the bathroom 910, the bathroom illumination 230 is not necessary and is turned off, and it can be considered that the bathroom exhaust fan is operated to exhaust the steam at the time of hot water supply. Therefore, the state in which the bathroom lighting 230 is turned off and the bathroom ventilation fan is operating may be a first pattern in which it is considered that the possibility that there is a person in the bathroom 910 is high.

  As the neighboring device state for the kitchen 920, for example, the state of the kitchen lighting 240, the kitchen ventilation fan, the IH cooker, the microwave oven, or the room air conditioner may be used, or each of the plurality of electric devices 200 among them may be used. A combination of states may be used.

  The contents of the first pattern that can be considered that there is a high possibility that there are people in the bathroom 910, the contents of the second pattern that can be considered that there is a low possibility that there are people in the bathroom 910, and the first that can be considered that there is a high possibility that there are people in the kitchen 920 The user may be able to change at least one of the contents of the pattern and the contents of the second pattern that can be regarded as having a low possibility that there is a person in the kitchen 920. You may comprise so that the user operation for making such a change can be received, for example by the bathroom remote control 310, the kitchen remote control 320, a personal computer, or a tablet. By enabling the user to change the contents of the first pattern or the second pattern, the following effects can be obtained.

  The contents of the first pattern or the second pattern can be determined according to the presence or absence of a window in the bathroom 910 or the kitchen 920, the positional relationship of the room including the bathroom 910 or the kitchen 920, the lifestyle of the user, and the like. As a result, the presence or absence of a person in the bathroom 910 or the kitchen 920 can be estimated with higher accuracy.

  FIG. 4 is a diagram illustrating an example in which the user can change the contents of the first pattern that can be considered that there is a high possibility that there is a person in the kitchen 920. In the example of FIG. 4, whether the kitchen lighting 240 is turned on or off, whether the IH cooker is in use or stopped, whether the microwave oven is in use or is stopped, The user can set the content of the first pattern by combining each condition of whether the presence sensor of the room air conditioner detects the presence or absence of a person. “Both” in FIG. 4 means that the contents of the first pattern are not used. That is, in the example of FIG. 4, whether the IH cooker is being used or stopped, and whether the microwave oven is being used or stopped are not used as the contents of the first pattern. In the example of FIG. 4, the content of the first pattern is that the kitchen lighting 240 is on and the presence sensor of the room air conditioner detects the presence of a person. That is, in this case, when the kitchen lighting 240 is on and the presence sensor of the room air conditioner detects that there is a person, the kitchen remote controller 320 assumes that there is a person in the kitchen 920. Performs a temperature change notice by voice from the voice output unit 303.

Embodiment 4 FIG.
Next, the fourth embodiment will be described with reference to FIG. 5. The description will focus on the differences from the above-described embodiment, and the description of the same or corresponding parts will be simplified or omitted. The configuration of hot water supply system 1 of the fourth embodiment may be the same as the configuration of FIGS. 1 and 2.

  In the fourth embodiment, the following is performed. The control unit 205 of the hot water supply apparatus 210 can acquire information related to the neighboring device state in real time via the HEMS controller 100. Based on the information acquired from the HEMS controller 100, the control unit 205 of the hot water supply apparatus 210 performs hot water supply to the first hot water tap 10 or the second hot water tap 20 at each of a plurality of patterns in which neighboring device states are classified. Learn the probability of being implemented. In the following description, a case where the probability of hot water supply to the second hot water tap 20 in the kitchen 920 is learned will be described as an example.

  FIG. 5 is a diagram for explaining learning of the probability that hot water is supplied to the second hot-water tap 20 in the fourth embodiment. In the example illustrated in FIG. 5, a combination of the states of the kitchen lighting 240, the kitchen ventilation fan, the IH cooker, and the microwave oven is used as the neighboring device state. The neighboring device states are classified into 16 patterns from No. 1 to No. 16 in FIG. 5 as follows. Whether the kitchen lighting 240 is on or off, whether the kitchen exhaust fan is operating or stopped, whether the IH cooker is operating within the past 10 minutes, and the microwave oven is operating within the past 10 minutes It is classified into 16 patterns depending on whether or not For example, in the second pattern, the kitchen lighting 240 is turned off, the kitchen exhaust fan is stopped, the IH cooker has not been operated within the past 10 minutes, and the microwave oven has been operated within the past 10 minutes. It is in a state of being. In the 15th pattern, the kitchen lighting 240 is lit, the kitchen exhaust fan is operating, the IH cooker is operating within the past 10 minutes, and the microwave oven is operating within the past 10 minutes. There is no state.

  The control unit 205 of the hot water supply apparatus 210 may learn the probability that hot water is supplied to the second hot-water tap 20 at each of the 1st to 16th patterns as follows. The control unit 205 of the hot water supply apparatus 210 can detect the presence or absence of hot water supply to the second hot water tap 20. The presence or absence of hot water supply to the second hot-water tap 20 may be detected by, for example, a signal from a flow rate sensor provided in the hot-water supply pipe 30b connected to the second hot-water tap 20. The control unit 205 of the hot water supply apparatus 210 periodically receives information on the state of neighboring devices from the HEMS controller 100 and determines whether or not hot water is currently supplied to the second hot water tap 20. Based on the received information, the control unit 205 of the hot water supply apparatus 210 classifies the current neighboring device state into one of patterns 1 to 16, and the number of the classified pattern and the second hot water tap 20. It is stored as one event in association with the presence or absence of hot water supply. Data relating to a large number of events is accumulated by periodically executing the process. Based on the stored data, the probability that hot water supply to the second hot-water tap 20 is performed at each of the patterns from No. 1 to No. 16 is learned. For example, among the events corresponding to the 16th pattern, the value obtained by dividing the number of events with hot water supply to the second hot water tap 20 by the total number of events corresponding to the 16th pattern is the 16th pattern. Alternatively, learning may be performed so as to regard the probability that hot water supply to the second hot-water tap 20 is performed. The example of FIG. 5 means that the learning result that the probability that hot water supply to the second hot-water tap 20 is performed in the case of the 16th pattern is 35.1% is obtained. In addition, although the example of the system which has the hot water supply presence / absence detection means to the 2nd hot-water tap 20 was described here, you may use the hot water supply presence / absence detection means built in the hot water supply apparatus 210. FIG. In that case, since the first hot water tap 10 (shower 11) and the second hot water tap 20 cannot be distinguished, the hot water prediction accuracy is lowered, but there is no need to provide a detection means for each hot water tap, so there is an economic merit. is there.

  Note that the process of learning the probability of hot water supply to the first hot-water tap 10 or the second hot-water tap 20 at each of a plurality of patterns in which neighboring device states are classified is replaced with the control unit 205 of the hot water supply device 210. Then, the HEMS controller 100 may execute.

  The hot water supply system 1 according to the fourth embodiment executes the control routine of FIG. 3 described above, but differs in the following points. In step S2 of FIG. 3, the control unit 205 of the hot water supply apparatus 210 is as follows. Judge whether the current neighboring device state for the kitchen 920 corresponds to any of the patterns 1 to 16, and learn the probability that the hot water supply to the second hot-water tap 20 is carried out in the case of the corresponding pattern Acquire based on the information. When the probability is larger than a reference (for example, 10%), the kitchen remote controller 320 executes a temperature change notice by voice from the voice output unit 303. When the probability is not larger than a reference (for example, 10%), the kitchen remote controller 320 does not execute the temperature change notice by voice from the voice output unit 303.

  According to the fourth embodiment, an effect similar to that of the second or third embodiment is obtained. That is, the following effects can be obtained. If the current neighboring equipment state of the kitchen 920 corresponds to a pattern in which the probability of hot water supply to the second hot water tap 20 is not large compared to the standard (for example, 10%), the second hot water tap 20 Since there is a low possibility of getting out of the hot water, it is less necessary for the kitchen remote controller 320 to perform a temperature change notice by voice. In this case, it is possible to prevent the user from feeling uncomfortable by unnecessary voice guidance by not performing the temperature change notice by voice. According to the fourth embodiment, even when the kitchen remote controller 320 does not include the human sensor 307, the above-described effect can be obtained, so that the cost can be reduced.

  In the fourth embodiment, the case of learning and controlling the probability of hot water supply to the second hot water tap 20 in the kitchen 920 has been described as an example, but by applying a similar method to the bathroom 910 You may learn and control the probability that the hot water supply to a certain 1st hot-water tap 10 will be implemented.

Embodiment 5. FIG.
Next, the fifth embodiment will be described with reference to FIG. 6. The description will focus on the differences from the above-described embodiment, and the description of the same or corresponding parts will be simplified or omitted. The configuration of hot water supply system 1 of the fifth embodiment may be the same as the configuration of FIGS. 1 and 2. The control in the fifth embodiment includes control similar to the control described in the second, third, or fourth embodiment.

  FIG. 6 is a flowchart of a control routine executed by hot water supply system 1 of the fifth embodiment. When the control unit 205 of the hot water supply apparatus 210 receives a hot water supply request from the tableware washing apparatus 220, the processing of the routine in FIG. 6 starts. Before step S21 in FIG. 6, the same processing as step S1 in FIG. 3 may be executed.

In step S21 of FIG. 6, the control unit 205 of the hot water supply apparatus 210 determines, for example, whether the possibility of hot water from the first hot water tap 10 / second hot water tap 20 is high or low as follows. To do.
(1) When the bathroom remote controller 310 / kitchen remote controller 320 includes the human sensor 307 as in the second embodiment, the first hot water tap 10 / When it is determined that there is a high possibility of hot water being discharged from the second hot-water tap 20, and when the human sensor 307 detects the absence of a person, the possibility of hot water being discharged from the first hot-water tap 10 / second hot-water tap 20 is low. May be determined.
(2) When the information on the neighboring device state can be acquired as in the third embodiment, when the current neighboring device state corresponds to the first pattern, the hot water is discharged from the first hot-water tap 10 / second hot-water tap 20 If the current neighboring device state corresponds to the second pattern, it may be determined that the possibility of discharging from the first hot-water tap 10 / second hot-water tap 20 is low.
(3) When learning the probability that hot water supply to the first hot-water tap 10 / second hot-water tap 20 is performed at each of a plurality of patterns in which neighboring device states are classified as in the fourth embodiment Is the first hot water supply when the probability of hot water supply to the first hot water tap 10 / second hot water tap 20 is larger than a reference (for example, 10%) when the current neighboring device state is a corresponding pattern. It may be determined that there is a high possibility that the hot water will be discharged from the tap 10 / second hot water tap 20, and otherwise, it may be determined that the possibility that the hot water will be discharged from the first hot water tap 10 / second hot water tap 20 is low.

  When it is determined that there is a high possibility that the first hot water tap 10 / the second hot water tap 20 will discharge the hot water, the process proceeds from step S21 to step S22. In step S22, the following is performed. The control unit 205 of the hot water supply apparatus 210 transmits a command for performing a temperature change notice to the bathroom remote controller 310 / kitchen remote controller 320. The bathroom remote controller 310 / kitchen remote controller 320 that has received the command executes a temperature change notice. That is, the audio output unit 303 of the bathroom remote controller 310 / kitchen remote controller 320 sends a speaker a voice message with a content for notifying that the set value of the hot water supply temperature is changed to the temperature for the dishwasher 220, that is, the second set temperature. Output from. Since the process after step S22 is the same as the process after step S3 of FIG. 3, description is abbreviate | omitted.

  When it is determined that there is a low possibility of hot water coming out of the first hot water tap 10 / second hot water tap 20, the process proceeds from step S21 to step S23. In step S23, the control unit 205 of the hot water supply apparatus 210 changes the set value of the hot water supply temperature from the first set temperature without causing the bathroom remote controller 310 / kitchen remote control 320 to execute a temperature change notice by voice from the voice output unit 303. Change to two preset temperatures. The process proceeds from step S23 to step S24.

  As described above, in the case of the fifth embodiment, when there is a low possibility that the first hot water tap 10 / second hot water tap 20 is discharged, it is not possible to prevent the temperature change notification by voice. The necessary voice guidance can prevent the user from feeling uncomfortable.

  In step S24, hot water supply to the dishwasher 220 is started. Since the process of step S24 is the same as step S4 of FIG. 3, description is abbreviate | omitted. The process proceeds from step S24 to step S25. In step S25, the control unit 205 of the hot water supply apparatus 210 determines whether or not the hot water supply to the tableware washing apparatus 220 has been completed. Whether or not the hot water supply to the dishwasher 220 has been completed can be determined by whether or not the hot water supply request from the dishwasher 220 continues. In step S25, when the hot water supply to the dishwasher 220 is completed, that is, when the hot water supply request from the dishwasher 220 is removed, the process proceeds to step S26. In step S <b> 26, the dishwasher 220 ends the operation, whereby hot water supply to the dishwasher 220 is stopped. The process proceeds from step S26 to step S27. In step S27, the set value of the hot water supply temperature is changed from the second set temperature to the normal set temperature, that is, the first set temperature. In this case, since there is a low possibility that the hot water tap 10 / second hot water tap 20 is discharged, there is no need to leave the set value of the hot water temperature changed. After step S27, the routine of FIG. 6 is terminated.

  If the hot water supply to the dishwasher 220 has not been completed in step S25, that is, if the hot water supply request from the dishwasher 220 continues, the process proceeds from step S25 to step S28. In step S28, the same method as in step S21 is used to determine again whether the possibility of hot water coming out of the first hot water tap 10 / second hot water tap 20 is high or low based on the latest information. If it is determined that there is a low possibility that the first hot-water tap 10 / second hot-water tap 20 is discharged, the process returns from step S28 to step S25.

If it is determined in step S28 that there is a high possibility that the hot water tap 10 / second hot water tap 20 will be discharged, the process proceeds to step S29. The case is, for example, one of the following cases.
(1) The human sensor 307 included in the bathroom remote controller 310 / kitchen remote controller 320 detects the absence of a person at step S21, but the human sensor 307 detects the presence of a person at step S28.
(2) The neighboring device state corresponds to the second pattern at the time of step S21, but the neighboring device state changes after that, and the neighboring device state corresponds to the first pattern at the time of step S28.
(3) At the time of step S21, although the probability that the hot water supply to the 1st hot-water tap 10 / the 2nd hot-water tap 20 is implemented was not large compared with a reference | standard (for example, 10%), the neighborhood apparatus state corresponded, Thereafter, the neighboring device state changes, and in step S28, the neighboring device state corresponds to a pattern in which the probability of hot water supply to the first hot-water tap 10 / second hot-water tap 20 is larger than a reference (for example, 10%). When it comes to.

  In step S <b> 29, control unit 205 of hot water supply apparatus 210 transmits a command of contents for performing temperature change notification to bathroom remote controller 310 / kitchen remote controller 320. The bathroom remote controller 310 / kitchen remote controller 320 that has received the command executes a temperature change notification. That is, in the audio output unit 303 of the bathroom remote controller 310 / kitchen remote controller 320, the set value of the hot water supply temperature is changed from the normal set temperature, that is, the first set temperature, to the second set temperature for the dishwasher 220. A voice message with a notification content is output from the speaker. The processing after step S29 is the same as the processing after step S5 in FIG.

  According to the fifth embodiment, the following effects can be obtained. In step S21, it is determined that there is a low possibility of hot water coming out of the first hot water tap 10 / second hot water tap 20, and the set value of the hot water temperature is changed from the first set temperature to the second set temperature without performing a temperature change notice by voice. It is also conceivable that the user starts using the first hot-water tap 10 / second hot-water tap 20 without knowing the change after the automatic change. In such a case, in the case of the fifth embodiment, the user can first determine whether or not the possibility that the hot water tap 10 / second hot water tap 20 is discharged is high or low in step S28. It is possible to detect whether or not there is a possibility of using the hot-water tap 10 / second hot-water tap 20. And when a user may use the 1st hot-water tap 10 / the 2nd hot-water tap 20, the preset value of the hot-water supply temperature is changed from the first preset temperature to the second preset temperature for the dishwasher 220. You can be notified to the user by voice. As a result, it is possible to prevent hot water having a temperature unintended by the user from flowing out of the first hot water tap 10 / second hot water tap 20, thereby reducing the user's comfort level and wasting water and energy. it can.

  In addition, when it transfers from step S29 of FIG. 6 to step S5 of FIG. 3, you may make it as follows. After changing the set value of the hot water temperature from the second set temperature to the first set temperature in step S8 or step S11 of FIG. 3, the first hot water tap 10 / It is determined again whether the possibility of hot water from the second hot water tap 20 is high or low. If it is determined that there is a low possibility of hot water being discharged from the first hot water tap 10 / second hot water tap 20, the audio output unit 303 of the bathroom remote control 310 / kitchen remote control 320 in step S9 or step S12 in FIG. A voice message notifying that the set value of the hot water supply temperature has been changed from the second set temperature to the first set temperature is not output from the speaker. In this way, it is possible to prevent the user from feeling uncomfortable due to unnecessary voice guidance.

When a user operation for canceling the temporary stop of the dishwasher 220 is input, the hot water supply system 1 performs the following. The voice output unit 303 of the remote controller 300 outputs a voice message that informs that the set value of the hot water supply temperature is changed to the temperature for the dishwasher 220, that is, the second set temperature, from the speaker. That is, the temperature change notice is executed. Thereafter, the control unit 205 of the hot water supply apparatus 210 changes the set value of the hot water supply temperature from the first set temperature to the second set temperature. In addition, the control unit 205 of the hot water supply apparatus 210 transmits a command requesting release of the temporary stop of the tableware washing apparatus 220 to the HEMS controller 100. The dishwasher 220 that has received the temporary suspension release request via the HEMS controller 100 resumes operation.

  If it is this Embodiment, the following effects are acquired by doing as mentioned above. A user who has finished using the first hot-water tap 10 or the second hot-water tap 20 with the tableware washing device 220 temporarily stopped performs a simple operation on the nearby remote controller 300, for example, a one-touch operation. The temporary stop of the cleaning device 220 can be released, and the set value of the hot water supply temperature can be returned to the second set temperature. For this reason, excellent usability can be obtained.

  The hot water supply system 1 according to the present embodiment may include means for performing a notification operation that prompts cancellation of the temporary stop of the dishwasher 220 when the temporary stop of the dishwasher 220 is not released for a certain period of time. For example, if the user operation for canceling the temporary stop is not input even after a certain time (for example, 10 minutes) has elapsed after the dishwasher 220 has been temporarily stopped, the remote controller 300 indicates that “the hot water supply is not used for a while. "Please press the operation resumption switch" may be displayed in text on the display unit 302 or may be output from the audio output unit 303 by voice. By doing so, it is possible to cope with a case where the user forgets to cancel the temporary stop of the dishwasher 220.

  The hot water supply system 1 according to the present embodiment is the case where the pause of the dishwasher 220 is not released even after a predetermined time has elapsed since the notification operation for prompting the release of the pause of the dishwasher 220 is performed. A means for automatically canceling the temporary stop of the dishwashing apparatus 220 may be provided in the case where the temporary stop of the dishwashing apparatus 220 is not canceled even if the notification operation for prompting the cancellation of the temporary stop of the apparatus 220 is repeated a plurality of times.
