  The heat storage amount detection unit 35 obtains a value corresponding to the heat storage amount of hot water in the hot water tank 2 based on monitor information related to detection of the heat storage amount of the operation status of the cogeneration hot water supply heat source device 3. The monitor information is, for example, information on the temperature detected by the hot water temperature detection sensors 101 to 111 in the hot water tank, information on the operating time of the power generator 1, and the like. The operating time of the power generation device 1 can be obtained from, for example, on / off information of the power generation device 1 and time information obtained from the timepiece mechanism 41. In addition, if a flow sensor is provided in the exhaust hot water introduction passage 14, information on the operation time of the power generation apparatus 1 can be obtained from information on the flow sensor.

  Here, an example of how to obtain a value corresponding to the heat storage amount of hot water in the hot water tank 2 is shown. For example, as the monitor information, the heat storage amount detection unit 35 takes in information on the temperature detected by the hot water temperature detection sensors 101 to 111 in the hot water tank, and the temperature detected by the hot water temperature detection sensor 105 in the hot water tank is about 60 ° C. Assuming that the temperature detected by the water temperature detection sensor 106 is about 20 ° C., the boundary line between the water and hot water in the hot water tank 2 as shown by the broken line A in FIG. 7 indicates the hot water temperature detection sensor 105 in the hot water tank and the hot water tank. It is determined that about 80 L of hot water at about 60 ° C. is accumulated in the hot water storage tank 2 between the internal hot water temperature detection sensor 106.

  Moreover, if the amount of hot water accumulated per unit time due to the operation of the power generation device 1 is given in advance to the heat storage amount detection unit 35 and this amount is 2 L per minute, for example, the time of the power generation device 1 obtained from the clock mechanism 41 When the information has passed for 30 minutes, the heat storage amount detection unit 35 determines that 60 L of hot water at about 60 ° C. is accumulated in the hot water storage tank 2. In this manner, the heat storage amount detection unit 35 can detect the amount of hot water in the hot water tank 2 from time to time based on the operating time information of the power generation device 1 obtained from the timepiece mechanism 41.

  Further, the heat storage amount detection unit 35 calculates the amount of hot water used in the hot water storage tank 2 from, for example, detection data of the flow rate sensor 70 and subtracts this value from the amount of hot water stored in the hot water storage tank 2, thereby The amount of hot water remaining in the tank 2 can be detected every moment, and the temperature of the hot water accumulated in the hot water storage tank 2 can be estimated from the elapsed time since the accumulation of hot water.

  The selection control unit 36 is a hot water supply heat source selection control unit. For example, when a value corresponding to the heat storage amount obtained by the heat storage amount detection unit 35 falls below a lower threshold value predetermined for heat source selection. The hot water supply heat source is switched from the hot water storage tank 2 to the auxiliary hot water supply heat source device 4 to perform hot water supply, and a value corresponding to the heat storage amount of the hot water in the hot water storage tank 2 determined by the heat storage amount detection unit 35 is determined in advance for the heat source selection. When the temperature rises above the upper threshold value, the hot water supply heat source is switched from the auxiliary hot water supply heat source device 4 to the hot water storage tank 2 of the cogeneration hot water supply heat source device 3 for hot water supply. In addition, the selection control of the hot water supply heat source by the selection control unit 36 is not particularly limited, and is appropriately set.

  In the present embodiment, a hot water supply passage (hot water supply path 12) fed from the hot water storage tank 2 of the cogeneration hot water supply heat source device 3 is communicated with a water supply inlet of the auxiliary hot water supply heat source device 4. When only hot water is used as a heat source and hot water of a set temperature or higher is sent from the hot water storage tank 2, the hot water of the hot water storage tank 2 is supplied to the hot water supply destination via the auxiliary hot water supply heat source device 4 in a non-heated drive state. Yes.

  That is, when hot water is supplied using the hot water in the hot water tank 2 as a heat source, the selection control unit 36 opens the hot water on / off valve 54 and adjusts the valve opening amounts of the hot water proportional valves 55 and 56 as appropriate. Hot water is mixed with water supplied from the water supply passage 11 via the branch passage 11b and sent to the auxiliary hot water supply heat source device 4 in a non-heated drive state as hot water at a set temperature. Then, for example, hot water having a set temperature introduced into the auxiliary hot water supply heat source device 4 is switched to the hot water path switching valve 58 to supply hot water to an appropriate hot water supply destination such as a kitchen through the branch passage 90, or the hot water open / close valve 59 is opened. Hot water filling is performed through the hot water introduction passage 95 and the hot water filling passage.

  Further, when the hot water supply heat source is switched to the auxiliary hot water supply heat source device 4, the selection control unit 36 closes the hot water on / off valve 54, for example, and supplies water introduced into the hot water mixing unit 10 from the water supply passage 11 through the branch passage 11 b. The hot water heater 5a is introduced through the connection passage 45, and a command is given to the combustion control unit 42 of the hot water heater 5a, and the hot water heater 5a is operated to supply hot water by the auxiliary hot water supply heat source device 4.

  When the selection control unit 36 selects the hot water supply operation from the auxiliary hot water supply heat source device 4, the combustion control unit 42 refers to the flow rate detected by the flow rate sensor 73 and turns on at least one of the gas on-off valves 81, 82, 83. Open and adjust the valve opening amount of the gas proportional valve 86 to adjust the amount of gas supplied to the burner 6 and also adjust the air volume of the combustion fan 8 to set the hot water discharged through the hot water supply heat exchanger 19. Combustion control of the burner 6 is performed so that the temperature becomes hot water.

  The hot water use amount data storage unit 38 flows the hot water use amount data for each time on the time axis for each provisional set period (for example, one day) with an integer multiple of one day (an integer multiple of 1) as a period. A plurality (for example, a predetermined number such as one month) is obtained and accumulated based on the information on the hot water flow rate obtained from the sensor 73 and the time information obtained from the clock mechanism 41. Examples of stored data are schematically shown in FIGS. 3 (a) and 3 (b). In FIG. 3, the amount of hot water used is indicated by L.

  The true set cycle setting unit 43 sets the temporary set cycle to true when the plurality of accumulated data accumulated by the hot water supply usage data accumulation unit 38 are all patterned for each temporary set cycle. When the plurality of accumulated data accumulated by the hot water use amount data accumulating unit is not patterned for each provisional set period, the time during which the hot water use amount is patterned from the plurality of accumulated data And set this time as the true setting period.

  For example, as shown in FIG. 3A, the true set cycle setting unit 43 is configured to use the temporary set cycle if the plurality of accumulated data accumulated by the hot water supply usage data accumulation unit 38 are all substantially the same pattern. For example, one day is set as a true setting cycle.

  On the other hand, in the true set cycle setting unit 43, as shown in FIG. 3B, for example, a plurality of accumulated data accumulated by the hot water supply usage data accumulation unit 38 is not patterned for each temporary set cycle. In this case, a time for patterning the amount of hot water supply usage is obtained from the plurality of accumulated data, and this time is set as a true setting cycle. In the case of FIG. 3B, if the accumulated data is grouped into three ones, it can be patterned as shown in FIG. 4, so the true set period is three times the tentative set period, Since it can be understood that 3 days is sufficient, the true setting cycle is 3 days.

  The true set cycle setting unit 43 adds the true set cycle information obtained as described above to the hot water supply usage amount patterning data storage unit 48. The hot water supply usage patterning data storage unit 48 stores the data of the pattern of hot water supply usage for each true setting cycle set by the true setting cycle setting unit 43.

  Bathtub pouring amount patterning data detection unit 49 obtains patterning data of the amount of pouring water into the bathtub for each true set period from the hot water supply usage amount data stored in patterning data storage unit 48. For example, the bath pouring amount patterning data detection unit 49 is provided with data on the capacity of the bath 126 in advance, and the bath pouring amount patterning data detection unit 49 stores this data and the hot water supply usage patterning data storage unit 48. By comparing with the stored hot water use amount data, it can be determined that the hot water supply amount of four-fifths of the capacity of the bathtub 126 is used at a time is pouring hot water into the bathtub 126. it can.

  In the present embodiment, the timing of pouring the user's bath 126 into the bathtub 126 can be determined as described above, and the user's bathing information can be detected based on the detection information of the water level sensor 125. it can.

  That is, conventionally, the water level sensor 125 has been used to determine the hot water level when, for example, hot water is filled automatically from a hot water source through a hot water passage, but the water level depends on the size (volume) of the person taking the bath. Since the fluctuation occurs, the bath water level information obtained from the water level sensor 125 is compared with the bath water level fluctuation amount reference data given in advance, so that the user's bathing information, for example, “A. Information such as “Mr. B takes a bath after 20 minutes” and “Mr. C (adult) and Ms. D (child) take a bath together around x hour ○”. Can be detected.

  The bathing information data storage unit 37 stores the user's bathing information as described above for each time on the time axis for each provisional set period having an integer multiple of one day (an integer multiple of 1) as a cycle. Based on the bath water level information obtained from the water level sensor 125 and the time information obtained from the clock mechanism 41, it is estimated and learned and stored, and a plurality of the data are accumulated.

  With reference to this accumulated data, the true set cycle setting unit 43 is configured such that when a plurality of accumulated data accumulated by the bathing information data accumulation unit 37 are all patterned for each temporary set cycle, When the provisional set period is set as a true set period, and the plurality of accumulated data accumulated by the bathing information data accumulation unit 37 are not patterned for each provisional set period, the plurality of accumulated data are used. The time for bathing information to be patterned is obtained, and this time is set as a true set period, and this true set period information is added to the bathing information pattern data storage unit 47. This true set cycle setting method is the same as the true set cycle setting method for hot water supply usage.

  The bathing information pattern data storage unit 47 stores the bathing information data patterned for each true set cycle set by the true set cycle setting unit 43.

  The hot water filling start time detection unit 39 refers to the data of the bath pouring amount patterning data detection unit 49 to obtain the hot water filling start time of the bathtub 126 on the time axis of the true set period, and bathing information patterning At least one of the operations for obtaining the hot water start time of the bathtub 126 on the time axis of the true set period with reference to the data in the data storage unit 47 is performed.

  In addition, when the hot water filling start time detection unit 39 refers to the data in the bathing information patterned data storage unit 47, the hot water filling start time of the bathtub 126 is obtained in correspondence with the estimated bathing start time of the user. When the person takes a bath, the bath start time of the person who takes the bath first is estimated, and the hot water start time of the bathtub 126 is obtained in correspondence with the estimated bath start time.

  Moreover, the hot water filling start time detection unit 39 refers to the data of the bath pouring amount patterning data detection unit 49 to obtain the hot water filling start time and the data of the bathing information patterning data storage unit 47 to refer to the hot water filling. When both of the operations for obtaining the start time are performed, the filling start time obtained by these operations is usually substantially the same time. However, if a difference occurs in the hot water filling start time obtained by both operations, for example, the time between them is determined as the hot water filling start time, and this information is added to the automatic hot water filling execution unit 40.

  The automatic hot water filling execution unit 40 takes in the time information obtained from the clock mechanism 41 and automatically supplies hot water from the hot water supply heat source at the hot water filling start time obtained by the hot water filling start time detection unit 39 to fill the hot water in the bathtub 126.

Therefore, it is possible to store hot water use amount data and bathing information data appropriate for the user, and to perform optimal hot water supply operation and hot water operation using the stored data.

  For example, in the present embodiment, the hot water usage pattern data storage unit 37 stores hot water usage data stored in the hot water usage pattern data, or the bathing information patterning is obtained. The hot water start time detection unit 39 obtains the hot water start time of the bathtub 126 on the time axis of the true setting cycle by referring to the bathing information data stored in the data storage unit 47, and the hot water start that has been obtained At the time, the automatic hot water filling execution unit 40 automatically supplies hot water from the hot water supply heat source and fills the bathtub 126, so that the hot water filling of the bathtub 126 can be performed automatically at a time suitable for the user.
