The type and number of power loads 260 included in the energy storage system 1000 may be arbitrary.

  The hot water storage type water heater 300 generates hot water using electric power supplied from at least one of the solar power generation device 220 and the system power supply 210 via the distribution board 240, and stores the generated hot water as heat energy therein. It is an energy storage device.

  FIG. 3 is a block diagram functionally showing a main part of the hot water storage type hot water heater 300 according to the first embodiment. The hot water storage type water heater 300 includes a heat pump type heating device 301, a hot water storage tank 306, a water flow path 307, a circulation pump 308, temperature sensors 310a, 310b, 310c, 310d, and 310e (hereinafter collectively referred to as temperature sensors). 310), a hot water discharge pipe 311, a water supply pipe 312, a flow rate sensor 313, an operation monitoring unit 320, a hot water storage state calculation unit 321, and a transmission unit 322.

  The hot water storage type water heater 300 operates the heat pump type heating device 301 using electric power supplied from at least one of the solar power generation device 220 and the system power source 210, and the heat pump type heating device 301 generates heat contained in the air. It is a water heater that collects and uses it for boiling water.

  In the hot water storage type water heater 300, the heat pump type heating device 301 is connected to the hot water storage tank 306 by the water flow path 307. When the heat pump type heating apparatus 301 is operated, the water flow path 307 is formed from the lower part of the hot water storage tank 306 as indicated by the solid line arrow. The water discharged in the flow flows in the order of the circulation pump 308 and the radiator 304 of the heat pump type heating device 301, and is supplied to the upper part of the hot water storage tank 306. The hot water storage tank 306 is configured by a sealed tank that stores hot water. The heat pump type heating device 301 includes an evaporator 302, a compressor 303, a radiator 304, and an expansion valve 305. When the heat pump type heating device 301 is operated, the heat pump type heating device 301 is separated from the evaporator 302 as indicated by a dotted arrow. The refrigerant moves in the direction passing through the compressor 303, the radiator 304, and the expansion valve 305.

  In the heat pump type heating device 301, heat in the air is absorbed by the refrigerant in the evaporator 302, and the refrigerant is compressed by the compressor 303, and the temperature rises. The refrigerant that has released heat by the radiator 304 is expanded and liquefied by the expansion valve 305, and the liquefied refrigerant returns to the evaporator 302. The water led to the radiator 304 by the circulation pump 308 from the lower part of the hot water storage tank 306 is heated by the heat released from the refrigerant and supplied to the upper part of the hot water storage tank 306. For this reason, in the hot water storage tank 306, temperature stratification is formed so that high temperature water stays on the upper side and low temperature water stays on the lower side.

  The hot water storage tank 306 is composed of a single section or a plurality of sections divided in the height direction. In the example of FIG. 3, the hot water storage tank 306 is divided into sections 309a, 309b, 309c, and 309d from the top to the bottom. , 309e. The sections 309a, 309b, 309c, 309d, and 309e are provided with temperature sensors 310a, 310b, 310c, 310d, and 310e that detect the water temperature in each section. The number and classification method of the hot water storage tank 306 and the number of temperature sensors 310 are arbitrary.

  Hot water heated by the heat pump heating device 301 is discharged from the hot water discharge pipe 311 provided at the upper part of the hot water storage tank 306 to the hot water supply pipe 30. The hot water storage tank 306 is supplied with the same amount of water discharged from the hot water discharge pipe 311 from a water supply pipe 312 connected to the water supply pipe 31. The water supply pipe 312 is provided below the hot water storage tank 306. A hot water sensor 313 is provided in the middle of the hot water pipe 311, detects the volume and temperature of hot water discharged from the hot water pipe 311, and outputs it to the hot water storage state calculation unit 321.

  The operation monitoring unit 320 monitors the operation of the heat pump type heating device 301. If the heat pump type heating device 301 is in a heating operation, the transmission unit 322 is supplied by the hot water storage hot water supply device 300 from a plurality of power supply sources. Hot water is generated using electric power, and a signal indicating that the generated hot water is being stored in the hot water storage tank 306 as heat energy is output to the network N1.

  The hot water storage state calculation unit 321 calculates the amount of stored energy stored in the hot water storage tank 306 and the amount of energy used to discharge from the hot water storage tank 306. The hot water storage state calculation unit 321 includes water temperatures T1, T2, T3, T4 and hot water stored in the sections 309a, 309b, 309c, 309d, and 309e of the hot water storage tank 306 detected by the temperature sensors 310a, 310b, 310c, 310d, and 310e, respectively. T5 (° C.) is acquired, and the stored energy amount Q (calories) stored in the hot water storage tank 306 is calculated using, for example, the following equation (1).

In the above equation (1), ρ _k (k = 1 to 5) is the water density (kilogram / liter) in each section 310 of the hot water storage tank 306, and the hot water in each section 310 detected by the temperature sensor 310. It is _obtained from the temperature Tk. In the above equation (1), c _k (k = 1 to 5) is the specific heat of water in each section 310 of the hot water storage tank 306 (calories / gram ° C.), and is obtained from the temperature T _k of hot water in each section 310. It is done. In the above equation (1), V _k (k = 1 to 5) is the volume (liter) of each of the sections 310a to 310e.

The hot water storage state calculation unit 321 acquires the capacity V _out (liter) and the temperature T _out (° C.) of hot water discharged from the hot water pipe 311 detected by the flow sensor 313, and uses, for example, the following equation (2) to store hot water The amount of energy used Q _out (calories) discharged from the tank 306 is calculated.

In the above equation (2), ρ _out is the density (kilogram / liter) of hot water discharged from the hot water pipe 311 and is obtained from the temperature T _{out of} hot water detected by the hot water sensor 313. c _out is the specific heat of water at T _out (calories / gram ° C).

  Instead of calculating the amount of hot water stored in the hot water storage tank 306 and the amount of hot water discharged from the hot water storage tank 306, the hot water storage state calculation unit 321 uses the above equations (1) and (2). The capacity (liter) of hot water stored in the hot water and the capacity (liter) of hot water discharged from the hot water storage tank 306 may be obtained. The capacity of the hot water stored in the hot water storage tank 306 is calculated as the stored energy amount V (liter) using, for example, the following equation (3).

In the above equation (3), the effective coefficient Ek is set to E _k = 1 when T _k ≧ predetermined temperature is satisfied, and E _k = 0 when T _k <predetermined temperature is satisfied. That is, the hot water storage state calculation unit 321 sets the capacity of hot water at a predetermined temperature or higher in the hot water storage tank 306 as the stored energy amount V of the hot water storage tank 306. The predetermined temperature is, for example, 45 ° C. For example, when the temperature sensors 310a and 310b detect 60 ° C. and the temperature sensors 310c, 310d, and 310e detect 40 ° C., the hot water storage state monitoring unit 321 determines whether the temperature of the hot water is 45 ° C. or higher. The sum (V _a + V _b ) of the volume is calculated as the stored energy amount V of the hot water storage tank 306.

  1 shows an example in which the display device 270 is connected to the network N1. However, the present invention is not limited to this. For example, the display device 270 and the information output control device 100 are connected via a network (not shown) different from the network N1. May be configured to communicate with each other. In that case, the energy storage system 1000 includes a network N1 that connects the information output control device 100, the power measuring device 250, and the hot water storage hot water heater 300, and a network N1 that connects the information output control device 100 and the display device 270. Has a separate network.

  Further, instead of the display device 270 communicating with the network 5 or the like, the information output control device 100 and the information output control device 100 can be connected to each other using a general-purpose standard such as RS-232C, USB (Universal Serial bus), HDMI (registered trademark), or an original standard.

  Further, the information output control device 100 and the display device 270 may be configured integrally. In this case, the number of devices related to the energy storage system 1000 can be reduced.

  FIG. 5 is an example of a screen that displays the stored energy amount of the hot water storage tank 306 according to the first embodiment. The screen shown in FIG. 5 is a screen displayed by the display device 270. The display device 270 displays a display mark D306 that schematically represents the hot water storage tank 306. The height of the display mark D306 indicates the maximum stored energy amount of the hot water storage tank 306.

  The display device 270 distinguishes and displays the energy amount stored using the first power and the energy amount stored using the second power in the display mark D306.

  In FIG. 5, the display D1061 indicates the amount of energy stored using the first electric power among the amount of energy stored in the hot water storage tank 306, and the display D1062 indicates the first amount of energy stored in the hot water storage tank 306. It shows the amount of energy stored using the second power.

  The display device 270 displays the display D1061 and the display D1062 separately by making the colors different from each other. For example, when the display D1062 indicating the amount of energy stored using the second power that is the generated power is displayed in green, the user can easily feel the energy saving effect. In addition to green, when displaying in orange, it is easy for the user to associate solar power generation, and the display device 270 can arbitrarily select colors representing the first power and the second power according to the user's preference. It may be possible to set to.

  The display device 270 displays the heights of the display D1061 and the display D1062 using the first power, the energy stored using the second power, and the maximum stored energy of the hot water storage tank 306. It depends on the amount. For example, when the energy amount stored using the second power is larger than the energy amount stored using the first power, the display device 270 sets the height of the display D1062 to be higher than the height of the display D1061. Also display higher. Further, the display device 270 is proportional to the ratio of the height of the display D1061 and the height of the display D1062 to the ratio of the energy amount stored using the first power and the energy amount stored using the second power. May be displayed.

  Display device 270 displays the height of display D1061 and display D1062 stacked closer to the height of display mark D306 as the amount of stored energy in hot water storage tank 306 approaches the maximum amount of stored energy.

  When the control unit 105 of the information output control device 100 outputs information on the stored energy amount, the display device 270 updates and displays the heights of the display D1061 and the display D1062. The heights of the display D1061 and the display D1062 change as the information on the stored energy amount output by the control unit 105 of the information output control apparatus 100 changes.

  In FIG. 5, the display D1062 indicating the amount of energy stored using the second power and the display D1061 indicating the amount of energy stored using the first power are in the upper or lower relationship. It doesn't matter. Further, the display device 270 not only displays the amount of stored energy on the display mark D306 schematically representing the hot water storage tank 306, but also stores the energy stored using the first power using a numerical value or a graph. The amount and the amount of energy stored using the second power may be displayed. Further, the display device 270 may display the stored energy amount displayed on the displays D1061 and D1062 as a ratio with respect to the maximum stored energy amount.

  Next, processing performed by the information output control apparatus 100 according to Embodiment 1 will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of the information output control process according to the first embodiment. The control program of the information output control device 100 is activated when the information output control device 100 is turned on, and is executed at predetermined intervals until the information output control device 100 is subsequently turned off.

  In step S101, the energy storage state acquisition unit 101 acquires the use energy amount Qout discharged from the hot water storage tank 306 from the hot water storage type water heater 300 via the network N1. Subsequent to step S101, the energy configuration calculation unit 104 acquires the amount of energy 1062 stored using the second power stored in the storage unit 106 in step S102 and the energy accumulation state acquisition unit 101 acquired in step S101. The amount of energy used Qout is compared.

  In step S102, when the used energy amount Qout discharged from the hot water storage tank 306 is equal to or less than the value of the energy amount 1062 stored using the second electric power, the energy configuration calculation unit 104 determines whether the second energy amount is calculated in step S103. The stored energy amount 1062 subtracted from the energy amount 1062 stored using electric power is subtracted, and the value after subtraction is stored in the storage unit 106 as an updated value of the energy amount 1062 stored using the second power. The process proceeds to step S104.

  In step S102, when the amount of used energy Qout discharged from the hot water storage tank 306 is larger than the value of the energy amount 1062 stored using the second electric power, the energy configuration calculation unit 104 determines whether the second energy amount is calculated in step S113. The amount of energy stored using the second power is all used by the tapping water, and the amount of energy 1062 stored using the second power is updated to zero and stored in the storage unit 106 again.

  Following step S113, in step S114, the energy configuration calculation unit 104 calculates the energy amount 1062 stored using the second electric power before being updated to zero from the used energy amount Qout discharged from the hot water storage tank 306. The amount of excess energy obtained by subtraction is subtracted from the amount of energy 1061 stored using the first power stored in the storage unit 106, and the value after subtraction is stored using the first power. The updated energy amount 1061 is stored in the storage unit 106, and the process proceeds to step S104.

  That is, when the hot water is discharged from the hot water storage tank 306, the energy configuration calculation unit 104 first uses the energy amount 1062 stored by using the second electric power out of the amount of hot water stored in the hot water storage tank 306, and uses the energy. When the energy amount 1062 stored using the second power reaches zero by subtracting the amount Qout, the used energy amount Qout is subtracted from the energy amount 1061 stored using the first power. That is, in the present embodiment, the remaining amount of the stored energy amount is calculated on the assumption that the energy stored using the second power is used preferentially.

  When there is no hot water from the hot water storage tank 306, the energy usage amount Qout acquired by the energy storage state acquisition unit 101 in step S101 is zero. In step S102, the second power stored in the storage unit 106 is always stored. In step S103, the energy configuration calculation unit 104 once again stores the same value as the energy amount 1062 stored using the second power stored in the storage unit 106 in the storage unit 106. It will be memorized.

  Here, if the used energy amount Qout is zero in step S102, the energy configuration calculating unit 104 also subtracts the energy amount 1062 stored by using the second power in step S103, and stores it in the storage unit 106. It is also possible to skip step S103 and proceed to step S104.

Is obtained from the hot water storage type water heater 300.

Following step S105, the first power acquisition unit 102 in step S106, the value of _{P s} (system power supplied from the system power supply 210) to the first power, the second power acquisition unit 103 in step S107, the the value of P _g (generated power supplied from the solar power generation apparatus 220) to second power, both via the network N1 and acquires from the power measurement device 250.

Following step S107, in step S108, the energy configuration calculation unit 104 obtains the energy usage state Q _out discharged from the hot water storage tank 306 acquired by the energy storage state acquisition unit 101 in step S101, and acquires the energy storage state in step S104. In the stored energy amount Q of the hot water storage tank 306 acquired by the unit 101 and the information output control process executed by the information output control device 100 at predetermined time intervals, the stored energy amount of the hot water storage tank 306 at the time of the previous processing execution From the stored energy amount Q ′, (Q−Q ′ + Q _out ) is calculated as the energy amount of the hot water generated by the hot water storage type hot water heater 300.

Following step S108, the energy configuration calculation unit 104 uses the following formulas (4) and (5) in step S109, for example, and the first power acquired by the first power acquisition unit 102 in step S106 the value of P _s, a second power P _g in accordance with the ratio between the value of the energy of the hot water storage type water heater 300 calculated in step S108 is generated by the second power acquisition unit 103 acquires at step S107 The amount is allocated to the energy amount Q _s stored using the first electric power and the energy amount Q _g stored using the second electric power.

In step S110, the energy configuration calculation unit 104 stores the energy amount Q _s stored using the first power distributed in step S109 and the energy amount Q _g stored using the second power. The value after the addition was updated by adding to the energy amount 1061 stored using the first power stored in the storage unit 106 and the energy amount 1062 stored using the second power, respectively. The storage unit 106 stores the energy amount 1061 stored using the first power and the updated value of the energy amount 1062 stored using the updated second power.

  In FIG. 12, a solid line L1 indicates the relationship between the voltage of the storage battery module 403 and the storage rate when the power storage device 400 is in a charging operation. A solid line L2 indicates the relationship between the voltage of the storage battery module 403 and the storage rate during the discharging operation of the power storage device 400. A solid line L3 indicates the relationship between the voltage of the battery module 403 and the storage rate when the power storage device 400 is on standby, that is, in a state where the charge / discharge operation is not performed. The power storage state calculation unit 405 may further consider the operation efficiency depending on the battery temperature of the power storage device 400.

  For example, the storage state calculation unit 405 obtains the relationship between the voltage of the storage battery module 403 and the storage rate in advance for each battery temperature range, and corresponds to the battery temperature of the storage battery module 403 measured by the battery management unit 402 and the voltage between terminals. The storage rate to be derived is derived from the relationship obtained in advance.

  In addition, the storage state calculation unit 405 may combine the method of calculating the charge / discharge amount by integrating the above-described current values and the method of deriving the storage rate corresponding to the inter-terminal voltage obtained in advance. For example, when the storage rate of the storage battery module 403 is within a predetermined range, the storage state calculation unit 405 calculates the storage rate from the charge / discharge amount obtained by integrating the current values measured by the battery management unit 402. In other words, when the storage rate of the storage battery module 403 falls below or exceeds a predetermined range, the storage rate corresponding to the terminal voltage measured by the battery management unit 402 is derived.

  The storage state calculation unit 405 may output the derived storage rate to the transmission unit 406 as the amount of energy stored in the storage battery module 403, or may calculate the storage amount from the storage rate and the maximum storage capacity to transmit the storage unit You may output to 406.

  The transmission unit 406 outputs the energy amount derived by the storage state calculation unit 405 to the network N1.

  Returning to FIG. 9, the information output control device 100 is storing the electric power supplied from at least one of the solar power generation device 220 and the system power supply 210 as electric energy in the storage battery module 403 or in the storage battery module 403. A signal indicating that the stored electric energy is being consumed and the amount of energy stored in the storage battery module 403 are acquired from the power storage device 400 via the network N1.

  The constituent elements of the information output control device 100 according to the modification of the first embodiment are configured such that each constituent element of the information output control device 100 according to the first embodiment handles information of the hot water storage hot water heater 300, instead of the power storage device 400. The difference is that it deals with information related to.

  The energy storage state acquisition unit 101 uses, as electrical energy, the power supplied from the power storage device 400 from at least one of the solar power generation device 220 and the system power supply 210, instead of the information related to the heat energy storage state of the hot water storage hot water heater 300. A signal indicating that the battery module 403 is accumulating, or a signal indicating that the electric energy accumulated in the battery module 403 is being consumed, and the amount of energy stored in the battery module 403 are stored via the network N1. Obtained from the device 400.

  The first power acquisition unit 102 acquires the value of the first power from the power measurement device 250 while the power storage device 400 is storing electrical energy in the storage battery module 403. The second power acquisition unit 103 acquires the value of the second power from the power measurement device 250 while the power storage device 400 is storing electrical energy in the storage battery module 403. The energy configuration calculation unit 104 calculates the first amount of energy stored in the storage battery module 403 acquired by the energy storage state acquisition unit 101 from the ratio between the value of the first power and the value of the second power. The amount of energy stored using electric power and the amount of energy stored using second electric power are calculated.

  The amount of power stored using the first power and the amount of power stored using the second power are the amount of energy 1061 stored using the first power and the second power, respectively. The stored energy amount 1062 is stored in the storage unit 106 and output to the display device 270 by the control unit 105 via the network N1.

  FIG. 13 is an example of a screen that displays the amount of stored energy of the storage battery module 403 according to the modification of the first embodiment. The screen shown in FIG. 13 is displayed on the display device 270. The display device 270 displays a display mark D396 schematically representing a battery instead of the display mark D306 schematically representing the hot water storage tank 306.

  The height of the display mark D396 indicates the maximum stored energy amount of the storage battery module 403, and the display device 270 displays a display D1961 indicating the amount of energy stored using the first power in the display mark D396, and a second A display D1962 indicating the amount of energy stored using electric power is displayed separately. FIG. 13 illustrates an example in which the display device 270 displays each energy amount using the storage rate. Not limited to this, the display device 270 may display each energy amount using the amount of stored electricity.

  Next, processing performed by the information output control apparatus 100 according to the modification of the first embodiment will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of the information output control process according to the modification of the first embodiment.

  In step S121, the energy accumulation state acquisition unit 101 indicates that the power storage device 400 is accumulating in the storage battery module 403 as electric energy supplied from at least one of the solar power generation device 220 and the system power supply 210. Alternatively, a signal indicating that the electric energy stored in the storage battery module 403 is being consumed and the amount of energy C stored in the storage battery module 403 are acquired from the power storage device 400. Following step S121, if the power storage device 400 is storing electrical energy in step S122, the energy storage state acquisition unit 101 sets the value of the first power Ps in step S123. In step S124, the second power acquisition unit 103 acquires the value of the second power Pg from the power measurement device 250 via the network N1.

  Subsequent to step S124, in step S125, the energy configuration calculation unit 104 determines the stored energy amount C of the storage battery module 403 acquired by the energy storage state acquisition unit 101 in step S121 and the information output control device 100 in advance. In the information output control process executed at regular intervals, the electric energy stored in the power storage device 400 from the stored energy amount C ′, which is the stored energy amount of the storage battery module 403 at the time of execution of the previous process, is stored. Calculate as a quantity.

Subsequent to step S125, the energy configuration calculation unit 104 uses the following formulas (6) and (7) in step S126, for example, to obtain the first power that the first power acquisition unit 102 acquires in step S123. According to the ratio between the value of P _{s and} the value of the second power P _g acquired by the second power acquisition unit 103 in step S124, the amount of electric energy accumulated in the power storage device 400 calculated in step S125 is and the amount of energy C _s energy stored using a first power distributed to the amount of energy C _g where stored using a second power.

In step S127, the energy configuration calculation unit 104 stores the energy amount C _s stored using the first power distributed in step S126 and the energy amount C _g stored using the second power. Each is added to the energy amount 1061 stored using the first power stored in the storage unit 106 and the energy amount 1062 stored using the second power. The energy configuration calculation unit 104 stores the value after the addition in the storage unit 106, similarly to step S110 in FIG. Subsequent to step S127, in step S128, the control unit stores the amount of energy 1061 stored using the first power and the amount of energy 1062 stored using the second power in the same manner as step S111 in FIG. Are notified via the network N1.

  In step S122, when the power storage device 400 is not storing electrical energy, the energy storage state acquisition unit 101 proceeds to step S129. In step S129, when the power storage device 400 is consuming electric energy, the energy configuration calculation unit 104 in step S130 stores the stored energy amount C of the storage battery module 403 acquired by the energy storage state acquisition unit 101 in step S121. From the stored energy amount C ′ that is the stored energy amount of the storage battery module 403 at the time of the previous processing execution, (C′−C) is calculated as the amount of electrical energy consumed by the power storage device 400.

  Following step S130, the energy configuration calculation unit 104 stores the amount of energy 1062 stored using the second power stored in the storage unit 106 in step S131 and the amount of energy consumed by the power storage device 400 calculated in step S130. (C'-C) is compared in size.

  In step S131, when the energy consumption amount (C′−C) of the power storage device 400 is equal to or less than the value of the energy amount 1062 stored using the second power, the energy configuration calculation unit 104 determines in step S132 that The amount of energy consumed (C′−C) is subtracted from the amount of energy 1062 stored using the second power, and the value after the subtraction is the updated value of the amount of energy 1062 stored using the second power. Is stored in the storage unit 106, and the process proceeds to step S128.

  In step S131, when the energy consumption amount (C′−C) of the power storage device 400 is larger than the value of the energy amount 1062 stored using the second power, the energy configuration calculation unit 104 determines in step S133. , Assuming that the amount of energy stored using the second power is all used by the discharging operation of the power storage device 400, the amount of energy 1062 stored using the second power is updated to zero, and the storage unit 106 Remember again.

  Following step S133, the energy configuration calculation unit 104 stores the amount of energy stored in step S134 using the second power before being updated to zero from the energy consumption amount (C′−C) of the power storage device 400. The excess energy amount obtained by subtracting 1062 is subtracted from the energy amount 1061 stored using the first power stored in the storage unit 106. The energy configuration calculation unit 104 stores the subtraction result in the storage unit 106 as an updated value of the energy amount 1061 stored using the first power, and proceeds to step S128.

  That is, as in the first embodiment, the energy configuration calculation unit 104 calculates the remaining amount of the stored energy amount by preferentially using the energy stored using the second power.

  In step S129, when power storage device 400 is not consuming electric energy, in step S129, in step S128, control unit 105 stores energy amount 1061 stored using the first power stored in storage unit 106.

The water outlet 363 discharges hot water illuminated by the light of the light source 368 to a bathtub or a sink.

  The light emitters constituting the light source 368 may be composed of two or less colors. In this case, although the types of colors that can be expressed are limited, the number of light emitters to be used can be reduced and the color can be configured at low cost.

  In addition to the position shown in FIG. 24, the light source 368 may be mounted above the water discharge port 363 so as to irradiate hot water flowing through the water discharge channel 362 from above the water discharge port.

  In addition, the spout 363 may be configured with a shower head capable of showering by forming two or more fine tapping holes, and a handle for switching between straight tapping and shower tapping is provided. It may be configured such that it can be switched between straight hot water and shower hot water by a handle operation.

  Next, the light source control process in the hot water outlet 360 according to Embodiment 3 will be described with reference to FIG. FIG. 25 is a flowchart illustrating an example of a light source control process in the hot water outlet 360 according to the third embodiment. The light source control process at the hot water outlet 360 is activated when the opening / closing operation detection unit 366 detects an opening operation of the opening / closing operation unit 365.

  When the opening / closing operation detection unit 366 detects the opening / closing operation of the opening / closing operation unit 365, the light source control unit 367 stores hot water in the water discharged to the water discharge channel 362 from the temperature setting operation detected by the opening / closing operation detection unit 366 in step S301. It is determined whether hot water in the tank 306 is included. If the light source control unit 367 determines in step S301 that the water discharged to the water discharge channel 362 contains hot water in the hot water storage tank 306, the process proceeds to step S302. In step S302, the reception unit 364 receives the energy amount 1062 stored using the second power from the information output control device 100 via the network N1.

  Subsequent to step S302, if the amount of energy 1062 stored using the second power received by the receiving unit 364 in step S302 is greater than zero in step S303, the light source control unit 367 proceeds to step S304. In step S304, the light source control unit 367 determines that the power supply source that has generated hot water contained in the hot water supplied from the water outlet 363 is the second power supply source, and changes the emission color of the light source 368 to the second power supply source. The color indicating is determined.

  The light source control unit 367 determines in advance the color indicating the second power supply source, for example, green so that the user can easily associate energy saving. Not limited to this, the light source control unit 367 may arbitrarily determine a color indicating the second power supply source, such as an orange color that is easily associated with solar power generation.

  Subsequent to step S304, the light source control unit 367 proceeds to step S305 and performs lighting control so that the light source 368 emits light with the emission color determined in step S304.

  In step S303, if the amount of energy 1062 stored using the second power received by the receiving unit 364 in step S302 is zero, the light source control unit 367 proceeds to step S306. In step S306, the light source control unit 367 determines the emission color of the light source 368 as a color indicating the first power supply source in order to indicate that hot water including hot water generated with the first power is being used. Then, the process proceeds to step S305. The light source controller 367 determines in advance that the color indicating the first power supply source is different from the color indicating the second power supply source, such as yellow. The light source control unit 367 is not limited to yellow, and may arbitrarily determine the color indicating the first power supply source as long as it is different from the color indicating the second power supply source.

  In step S301, when the light source control unit 368 determines that the hot water in the hot water storage tank 306 is not discharged, the process proceeds to step S309, and the emission color of the light source 368 is not defined. That is, following step S309, in step S305, the light source control unit 368 does not perform lighting control of the light source 368.

  Subsequent to step S305, when the opening / closing operation detection unit 366 detects the closing operation of the opening / closing operation unit 365 in step S307, the light source control unit 367 controls the light source 368 to be turned off in step S308, and the light source control process ends. To do.

  If the opening / closing operation detection unit 366 does not detect the closing operation of the opening / closing operation unit 365 in step S307, the process returns to step S301, and the light source control process is repeated.

  In step S305, the light source controller 367 controls the lighting of the light source 368 with the light emission color determined in step S304 or step S306, so that the light source 368 emits light. The light emitted by the light source 368 is refracted by hot water or reflected on the inner surface of the water discharge channel 362 and directed toward the water discharge port 363, and the water discharge port 363 illuminates the hot water discharged to the bathtub or sink. To the user's eyes, it looks as if the hot water was colored.

  FIG. 26 is a diagram showing the relationship between the amount of hot water and the operation of the hot water outlet in the energy storage system 3000 according to the third embodiment.

Time T ₁ shows a state in which the opening / closing operation unit 365 is operated and the hot water outlet 360 starts water discharge including hot water in the hot water storage tank 306. Since the amount of energy 1062 stored using the second power at time T ₁ is the same as that at time T ₀ , the light source control unit 367 is using hot water generated using the second power. In order to show this, the light emission color of the light source 368 is changed to a color indicating the second power supply source, and lighting control is performed. FIG. 26 shows an example in which the color indicating the second power supply source is green. Thereby, the light source 368 illuminates hot water discharged from the water outlet 363 with a color indicating the second power supply source.

Unplugging operation subsequent handling portions 365 at time T _1, the value of the second energy amount 1062 stored using power decreases with the use of hot water.

Time T _2, shows a state in which the amount of energy 1062 stored using the second power is zero. At time T _2, the light source control unit 367, shown in order to indicate that it is in use hot water, the color of light emitted by the light source 368 first power sources including hot water generated using a first power Control lighting with color. Thereby, the light source 368 changes the color which illuminates the hot water discharged from the water outlet 363 from the color indicating the second power supply source to the color indicating the first power supply source. FIG. 26 shows an example in which the color indicating the first power supply source is yellow.

Time T ₃ shows a state where the opening and closing operation unit 365 is stoppered operation. The light source control unit 367 controls to turn off the light source 368 and ends the light irradiation.

  As described above, according to the energy storage system 3000 according to the third embodiment, the hot water storage hot water heater 300 includes hot water accumulated in the hot water storage tank 306 and illuminates hot water discharged from the hot water outlet 360. 368 and a light source control unit 367 for controlling the light source 368 corresponding to the power supply source used to generate the hot water accumulated in the hot water storage tank 306, and the information output control device 100 transmits the second Since the light source control unit 367 causes the light source 368 to emit light in a different manner based on the amount of thermal energy 1062 stored using electric power, the user of the hot water outlet 360 looks at the hot water discharged from the water outlet 363. Simply identify whether the energy source used to generate the hot water contained in the hot water is the first or second power source. It is possible. Thereby, even when the display device 270 described in the first embodiment and the second embodiment is not arranged near the hot water outlet 360, the user uses the energy supply source used to generate hot water in use. Can be identified as the first power supply source or the second power supply source.

  Further, according to the energy storage system 3000 according to the third embodiment, the light source control unit 367 is a color indicating the first power supply source based on the amount of thermal energy stored using the second power, or Since the light source 368 emits light in one of the colors indicating the second power supply source, the user determines whether the energy supply source used to generate hot water in use is the first power supply source, It is possible to identify whether it is a power supply source.

  In general, when the hot water outlet 360 is used, the user's line of sight is often directed to the vicinity of the water outlet 363. Therefore, the hot water source is used based on the energy supply source used to generate the hot water contained in the hot water used. By changing the light emitted from the light source 368 provided at the tip 360, the user can generate hot water contained in the hot water being used without having to look at the display device 270 during bathing or cooking. It is possible to identify whether the used energy supply source is the first power supply source or the second power supply source.

  The user can recognize that the energy supply source used to generate hot water in use is the second power supply source, so that the user is aware of the benefits of the power generation device that is the second power supply source. can do. Further, when the amount of energy 1062 stored using the second power stored in the storage unit 106 of the information output control device 100 becomes zero, the light emitted by the light source 368 provided in the hot water outlet 360 is changed. Therefore, the user can recognize that the energy supply source used to generate hot water in use has changed. This will lead to energy saving activities such as suppressing the use of hot water.

  In addition, by changing the light emitted from the light source 368 provided at the hot water outlet 360 based on the power supply source used to generate hot water in use, even children and elderly people can generate hot water. The power source used can be identified intuitively, and energy conservation activities can be promoted regardless of age.

(First modification of the third embodiment)
As described above, based on the value of the amount of energy 1062 stored using the second power acquired from the information output control device 100, the light source 368 provided in the hot water outlet 360 is displayed in the color indicating the first power supply source or The energy storage system 3000 that emits light in one of the colors representing the two power supply sources has been described.

  Not limited to this, the light source control unit 367 of the hot water outlet 360 controls the light emission color of the light source 368 to change stepwise from the color indicating the second power supply source to the color indicating the first power supply source. It may be a configuration. A first modification of the third embodiment configured as described above will be described below. The energy storage system 3100 according to the first modification of the third embodiment is the same as the energy storage system 3000 of the third embodiment except for the operation of the hot water outlet 360. The light source control process of the hot water outlet 360 in the energy storage system 3100 will be described with reference to FIG. FIG. 27 is a flowchart showing an example of a light source control process in the hot water outlet 360 according to the first modification of the third embodiment.

  In FIG. 27, the processing from step S301 to step S309 is the same as the processing from step S301 to step S309 described in FIG. Following step S302, the light source control unit 367 proceeds to step S304 if the amount of energy 1062 stored using the second power received by the receiving unit 364 is greater than a predetermined value q in step S310. If the amount of energy 1062 stored using the second power is equal to or less than q, the process proceeds to step S303.

  In step S303, if the amount of energy 1062 stored using the second power is greater than zero, the process proceeds to step S311. If the amount of energy 1062 stored using the second power is zero, the process proceeds to step S306.

  That is, if the amount of energy 1062 stored using the second power in step S310 is equal to or less than q in step S310, the light source control unit 367 uses the amount of energy 1062 stored using the second power in step S303. In step S311, an intermediate color expressed by mixing the color indicating the second power supply source and the color indicating the first power supply source is set as the light emission color of the light source 368 until it becomes zero.

  The light source control unit 367 may use a color obtained by mixing the color indicating the second power supply source and the color indicating the first power supply source at the same ratio as an intermediate color, or may have a plurality of intermediate colors having different mixing ratios. Good. In that case, for example, the light source control unit 367 obtains a ratio of the amount of energy 1062 stored using the second power to q, sets the obtained ratio as a color mixture ratio indicating the second power supply source, and the rest The intermediate color is expressed by using the ratio of the color as the color mixture ratio indicating the first power supply source.

FIG. 28 is a diagram showing the relationship between the amount of hot water and the operation of the hot water outlet in the energy storage system 3000 according to the first modification of the third embodiment. The energy amount 1061 stored using the first power at each of the times T ₀ , T ₁ , T ₂ , T ₃ in FIG. 28, the energy amount 1062 stored using the second power, and the opening / closing operation unit 365. This operation is the same as the times T ₀ , T ₁ , T ₂ , T ₃ in FIG.

Time T ₄ in FIG. 28, after unplugging operation of the opening and closing operation unit 365 at time T _1, the value of the second energy amount 1062 stored using power is reduced with the lapse of time, a predetermined The state where the value q is reached is shown.

Time T ₄ after, during the time T _2, until the amount of energy 1062 stored using the second power is zero, the light source control unit 367, color and first power of a second power supply source The light source 368 emits light with an intermediate color mixed with a color indicating the supply source. As the value of the amount of energy 1062 stored using the second power decreases, the light source control unit 367 mixes the color indicating the first power supply source rather than the color indicating the second power supply source. Is increased to form a neutral color. For example, the time T ₄ after the value of the second energy amount 1062 stored using power received from the information output control device 100 q / 3 decreases, the light source control unit 367, a second power decrease The red amount corresponding to the amount of energy 1062 used and stored is emitted.

Further, the value of the energy amount 1062 stored using the second power received from the information output control device 100 decreases by q / 3, that is, the value of the energy amount 1062 stored using the second power is q. When / 3 is reached, the light source control unit 367 increases the red light emission degree and causes the light source 368 to emit light. By the light source control unit 367 is controlled to emit light of the light source 368 in this way, from time T ₄ the value of the amount of energy 1062 stored using a second power approaches zero, stored using the second power the value of the amount of energy 1062 over the time T _2, which is a zero, the color of the light source 368 is gradually changed from green to yellow.

  As described above, according to the energy storage system 3100 according to the first modification of the third embodiment, the light source control unit 367 has the energy amount 1062 stored using the second power determined in advance. When the value is less than or equal to the value, the color indicating the second power supply source and the color indicating the first power supply source are caused to emit light based on the amount of energy 1062 stored using the second power. Therefore, it can be recognized that the energy supply source used by the user to generate hot water in use will change soon. This leads to energy saving activities such as suppressing the use of hot water thereafter.

(Second modification of the third embodiment)
As described above, when the light source control unit 367 of the hot water outlet 360 includes hot water in the hot water storage tank 306 in the water discharged from the water outlet 363, energy storage for causing the light source 368 to emit light in a color indicating the power supply source that generated the hot water. The systems 3000 and 3100 have been described. However, the light source control unit 367 emits the light source 368 even when the water discharged from the water outlet 363 does not contain hot water in the hot water storage tank 306, that is, when water flowing in from the water supply pipe 31 is discharged. You may control so. A second modification of the third embodiment configured as described above will be described below. The energy storage system 3200 according to the second modification of the third embodiment is the same as the energy storage systems 3000 and 3100 of the third embodiment except for the operation of the hot water outlet 360. The light source control process of the hot water outlet 360 in the energy storage system 3200 will be described with reference to FIG. FIG. 29 is a flowchart showing an example of the light source control process in the hot water outlet 360 according to the second modification of the third embodiment.

  In FIG. 29, the processing from step S302 to step S308 is the same as the processing from step S302 to step S308 described in FIG. In step S303, the light source control unit 367 proceeds to step S304 if the energy amount 1062 stored using the second power received by the receiving unit 364 in step S302 is greater than zero, and uses the second power. If the amount of stored energy 1062 is zero, the process proceeds to step S306. Since the light source control unit 367 in the present embodiment does not determine whether the hot water in the hot water storage tank 306 is included in the water discharged in step S301, the light source 368 is always supplied with the first power supply during the water discharged from the water outlet 363. Control is performed to emit light in either the color indicating the source or the color indicating the second power supply source.

  As described above, according to the energy storage system 3200 according to the second modification of the third embodiment, even when the light source control unit 367 does not include hot water in the hot water storage tank 306 in the water discharged from the hot water outlet 360. Based on the amount of energy 1062 stored using the second power, the light source 368 emits light in either the color indicating the first power supply source or the color indicating the second power supply source. When switching the discharged water to hot water from now on, it is possible to recognize in advance whether the hot water after the switching is generated by the first power supply source or the second power supply source. Thus, for example, when the user switches the discharged water from water to hot water, the user can easily switch to hot water by recognizing in advance that the power supply source that generated the hot water after switching is the second power supply source. be able to.

(Third Modification of Embodiment 3)
As described above, the energy storage system 3000, 3100, in which the light source control unit 367 causes the light source 368 to emit light in a color indicating the first power supply source, a color indicating the second power supply source, or a color expressed by mixing them. 3200 has been described. In addition to the above, the light source control unit 367 may control the light source 368 to emit only the color indicating the first power supply source or the color indicating the second power supply source. A third modification of the third embodiment configured as described above will be described below. The energy storage system 3300 according to the third modification of the third embodiment is the same as the third modification, the first modification of the third embodiment, and the second of the third embodiment, except for the operation of the hot water outlet 360. This is the same as the energy storage system 3000, 3100, 3200 described in the modified example. The light source control process of the hot water outlet 360 in the energy storage system 3300 will be described with reference to FIG. FIG. 30 is a flowchart showing an example of a light source control process in the hot water outlet 360 according to the third modification of the third embodiment.

  In FIG. 30, when hot water generated using the second power is used, the light source control unit 367 causes the light source 368 to emit light, and the hot water generated using the first power is used. In this example, the light source control unit 367 controls the light source 368 not to emit light. In FIG. 30, the processing from step S301 to step S305 and from step S307 to step S308 are the same processing as described in FIG.

  In step S303, if the amount of energy 1062 stored using the second power is zero, the light source control unit 367 proceeds to step S309. In step S309, the light source control unit 367 does not define the emission color of the light source 368. That is, following step S309, in step S305, the light source control unit 368 does not control lighting of the light source 368.

FIG. 31 is a diagram showing the relationship between the amount of hot water and the operation of the hot water outlet in an energy storage system 3300 according to a third modification of the third embodiment. The energy amount 1061 stored using the first power at each of the times T ₀ , T ₁ , T ₂ , T ₃ in FIG. 31, the energy amount 1062 stored using the second power, and the opening / closing operation unit 365. This operation is the same as the times T ₀ , T ₁ , T ₂ , T ₃ in FIG.

When the amount of energy 1062 stored using a second power at time T _2, it becomes zero, the light source control unit 367 stops the light emission of the light source 368. Thus, the time T _2, since, as the eyes of the user of the tapping destination 360, a hot water containing a hot water second power supply source is generated by the power supply only during the water discharge, with the color hot water Looks like.

  In the present embodiment, the example in which the light source control unit 367 controls the light source 368 to emit only the color indicating the second power supply source has been described. Of course, the light source control unit 367 has the first power supply. The light source 368 may be configured to emit only the color indicating the source. In that case, in step S303, if the amount of energy 1062 stored using the second power is zero, the light source control unit 367 supplies the emission color of the light source 368 to the first power supply instead of proceeding to step S309. Determine the color to indicate the source. On the other hand, if the amount of energy 1062 stored using the second power is larger than zero in step S303, the light source control unit 367 does not define the emission color of the light source 368 instead of proceeding to step S304. 368 is prevented from emitting light.

  As described above, according to the energy storage system 3300 according to the third modification of the third embodiment, the light source control unit 367 is based on the amount of thermal energy stored using the second power. The light source 368 emits light only when hot water generated using the power supplied by the second power supply source is used or when hot water generated using the power supplied by the second power supply source is used. The hot water outlet 360 can reduce the power required for the light emission of the light source 368.

(Fourth modification of the third embodiment)
In the third modification of the third embodiment described above, light emission of a color indicating that the light source control unit 367 is the second power supply source by the value of the energy amount 1062 stored using the second power. The light source 368 may be controlled to change the degree. A fourth modification of the third embodiment configured as described above will be described below. The energy storage system 3400 according to the fourth modified example of the third embodiment has been described in the third modified example from the first modified example of the third embodiment and the third embodiment except for the operation of the hot water outlet 360. It is the same as the energy storage system 3000, 3100, 3200, 3200. A light source control process of the hot water outlet 360 in the fourth modification of the third embodiment will be described with reference to FIG. FIG. 32 is a flowchart showing an example of a light source control process in the hot water outlet 360 according to the fourth modification of the third embodiment.

  In FIG. 32, the processing from step S301 to step S305 and the processing from step S307 to step S310 are the same processing as described in FIG. If the amount of energy 1062 stored using the second power is less than or equal to q in step S310, the light source control unit 367 sets the amount of energy 1062 stored using the second power to zero in step S303. Until it becomes, in step S312, the light emission degree of the light source 368 is determined according to the value of the energy amount 1062 stored using the second electric power.

FIG. 33 is a diagram showing the relationship between the amount of hot water and the operation of the hot water outlet 360 in the energy storage system 3400 according to the fourth modification of the third embodiment. 33. Energy amount 1061 stored using the first power at each of times T ₀ , T ₁ , T ₂ , T ₃ , T ₄ in FIG. 33, energy amount 1062 stored using the second power, opening and closing The operation of the operation unit 365 is the same as the times T ₀ , T ₁ , T ₂ , T ₃ , T ₄ in FIG.

In a second value the time T ₄ the energy 1062 stored using power, after reaching a predetermined value q, during the time T _2, until zero, the light source control unit 367, a light source It is lowered slowly than that of the light-emitting degree of up to 368 at a time T _4. For example, after time T ₄ , when the value of the energy amount 1062 stored using the second power received from the information output control device 100 decreases by q / 3, the light source control unit 367 sets the light emission degree of the light source 368 to the time. than the emission degree of up to T ₄ q / 3 down to emit light in a color of a second power supply source. FIG. 33 shows an example in which the color indicating the second power supply source is green.

Further, the value of the energy amount 1062 stored using the second power received from the information output control device 100 decreases by q / 3, that is, the value of the energy amount 1062 stored using the second power is q. Upon reaching the / 3, the light source control unit 367, and the light emission degree of q / 3 of up to the light emission degree of the light source 368 at time _{T 4,} causes light sources 368. Light source control unit 367 by the light emission control of the light source 368 in this way, over a period from time T ₄ to time T _2, the light emitting degree of the light source 368 is gradually lowered.

  Similarly to the first modification of the third embodiment, the light emission level of the light source 368 is decreased stepwise before the value of the amount of energy 1062 stored by the light source control unit 367 using the second power becomes zero. By doing so, the user can be conscious of suppressing the use of hot water. As described above, according to the energy storage system 3400 according to the fourth modification of the third embodiment, the energy amount 1062 stored by the light source control unit 367 using the second power is a predetermined value. When the energy supply source used by the user to generate hot water in use by causing the light source 368 to emit light at a light emission degree corresponding to the amount of energy 1062 stored using the second power when Recognize that it will change soon. Thereby, like the 1st modification of Embodiment 3, it is connected with the energy-saving activity of suppressing utilization of subsequent hot water.

(Embodiment 4)
In the first to fourth modifications of the third embodiment and the third embodiment described above, the tapping water is based on the value of the energy amount 1062 stored using the second power acquired from the information output control device 100. The light source controller 367 of the previous 360 causes the light source 368 to emit light. The energy storage system shown in the fourth embodiment includes a light source 368 provided in the hot water outlet 360 based on which power supply source is the energy supply source output by the information output control device 120 of the second embodiment. The light source control unit 367 controls it. The energy storage system shown in Embodiment 4 configured as described above will be described below.

  The energy storage system 4000 according to the fourth embodiment is the same as the energy storage system 3000 except that the information output control device 100 of the energy storage system 3000 of the third embodiment is replaced with the information output control device 120, and a description thereof is omitted. To do. The receiving unit 364 of the hot water outlet 360 in the energy storage system 4000 receives which power supply source is the energy supply source from the information output control device 120 instead of the value of the amount of energy 1062 stored using the second power. A signal indicating whether or not the data has been received is received via the network N1. The light source control unit 367 of the hot water outlet 360 causes the light source 368 to emit light with a color corresponding to the energy supply source received by the receiving unit 364. The light source control processing of the hot water outlet 360 in the energy storage system 4000 will be described with reference to FIG.
