[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-119829 Summary of the Invention [Problem to be solved by the invention]

[0004] When facility equipment performs power outage countermeasure operation, it may be advisable for the user to perform preliminary operations corresponding to the power outage countermeasure operation, such as preparatory operations required for the power outage countermeasure operation and auxiliary operations for further enhancing the effectiveness of the power outage countermeasure operation, before the power outage countermeasure operation is performed. This specification provides a technology that can prevent facility equipment from performing power outage countermeasure operation without the user having performed preliminary operations. [Means for solving the problem]

[0005] In a first aspect of the present technology, an equipment system may include equipment installed in a residence and a power outage prediction device that predicts a power outage in the residence. When the power outage prediction device predicts a power outage in the residence, the equipment may be configured to perform a power outage countermeasure operation at a first time earlier than the time when the power outage is predicted to occur, and to notify a user at a second time earlier than the first time, prompting the user to perform a preparatory operation corresponding to the power outage countermeasure operation. Note that, in this specification, the preparatory operation for the power outage countermeasure operation refers to one or both of a preparatory operation required for the power outage countermeasure operation and an auxiliary operation for further enhancing the effectiveness of the power outage countermeasure operation.

[0006] According to the above configuration, it is possible to prompt the user to perform a preparatory operation before the facility device performs a power outage countermeasure operation, thereby preventing the facility device from performing a power outage countermeasure operation without the user having performed a preparatory operation.

[0007] In a second aspect of the present technology, in the first aspect, the advance operation may include a preparatory operation required for the power outage countermeasure operation.

[0008] According to the above configuration, it is possible to prevent the facility equipment from executing power outage countermeasure operation when the user has not performed the preparatory operation required for power outage countermeasure operation.

[0009] In a third aspect of the present technology, in the first or second aspect described above, the facility equipment may be configured to perform the power outage prevention operation if the user gives permission to perform the power outage prevention operation after sending a notification to the user urging them to perform the preliminary operation, and not to perform the power outage prevention operation if the user does not give permission to perform the power outage prevention operation.

[0010] For example, if a user is out, even if the user receives a notification urging the user to perform preparatory action corresponding to power outage countermeasure operation, the user is unable to perform the preparatory action. In such a case, if the power outage countermeasure operation is performed, there is a risk that the facility equipment will perform power outage countermeasure operation without the user having performed the preparatory action. According to the above configuration, after the facility equipment has sent a notification urging the user to perform the preparatory action, if the user does not permit the facility equipment to perform the power outage countermeasure operation, the facility equipment will not perform the power outage countermeasure operation. This makes it possible to prevent the facility equipment from performing power outage countermeasure operation without the user having performed the preparatory action.

[0011] In a fourth aspect of the present technology, in the first or second aspect, the facility equipment system may further include a sensor capable of detecting whether the pre-operation has been performed. After issuing a notification urging the user to perform the pre-operation, the facility equipment may be configured to perform the power outage countermeasure operation if the sensor detects that the pre-operation has been performed, and not to perform the power outage countermeasure operation if the sensor does not detect that the pre-operation has been performed.

[0012] According to the above configuration, the facility device does not execute power outage countermeasure operation if the sensor does not detect that the preparatory action has been executed after the notification urging the user to execute the preparatory action has been sent to the user. This makes it possible to prevent the facility device from executing power outage countermeasure operation without the user having performed the preparatory action.

[0013] In a fifth aspect of the present technology, in any one of the first to fourth aspects, the power outage countermeasure operation may include filling a bathtub with water or hot water. The preliminary action may include closing a drain valve of the bathtub.

[0014] When filling the bathtub with water or hot water as a backup operation in case of a power outage, it is necessary to close the bathtub drain valve beforehand. With the above configuration, it is possible to prevent the bathtub filling operation or hot water filling operation from being performed when the bathtub drain valve is not closed.

[0015] In a sixth aspect of the present technology, in any one of the first to fifth aspects, the power outage countermeasure operation may include filling a bathtub with water, and the preliminary action may include closing a bathtub lid.

[0016] When filling the bathtub with water as a backup for power outages, if the bathtub lid is not closed beforehand, the temperature of the water stored in the bathtub may drop due to heat radiation to the surrounding area. With the above configuration, it is possible to prevent the bathtub from being filled with water when the bathtub lid is not closed.

[0017] In a seventh aspect of the present technology, in any one of the first to sixth aspects, the power outage countermeasure operation may include a heating operation or a cooling operation of a room, and the preparatory action may include an action of closing a window or a door of the room.

[0018] When performing heating or cooling operation in a room as a power outage countermeasure operation, if the room windows and doors are not closed in advance, there is a risk that the air heated by the heating operation or the air cooled by the cooling operation will leak from inside the room to the outside. With the above configuration, it is possible to prevent the heating or cooling operation from being performed in a room when the room windows or doors are not closed.

[Figure 7] 10 shows yet another example of a flowchart of power outage countermeasure operation of the facility device 2 according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0020] (Example) 1, the facility equipment system 200 of this embodiment includes a facility equipment 2, a server device 210, and a terminal device 220. The server device 210 is capable of communicating with each of the facility equipment 2, the terminal device 220, and an external server device 300 via the Internet.

[0021] (Configuration of Equipment 2) 2, the facility equipment 2 of this embodiment is a thermal equipment installed in a user's house. The facility equipment 2 includes a tank unit 4, a HP unit 6, and a combustion unit 8.

[0022] (HP Unit 6 Configuration) The HP unit 6 includes a refrigerant circulation path 52 for circulating a refrigerant (for example, an HFC refrigerant such as R410A or a CO2 refrigerant such as R744), an air heat exchanger 54, a fan 56, a compressor 62, a three-fluid heat exchanger 58, an expansion valve 60, and a tank circulation pump 22.

[0023] The air heat exchanger 54 exchanges heat between outside air blown by the fan 56 and the refrigerant in the refrigerant circuit 52. The compressor 62 pressurizes the gas-phase refrigerant and sends it out. The three-fluid heat exchanger 58 exchanges heat between the refrigerant in the refrigerant circuit 52 and water in a tank circuit 20 (described later). And / or the three-fluid heat exchanger 58 exchanges heat between the refrigerant in the refrigerant circuit 52 and heating water in an HP circuit 88 (described later). The expansion valve 60 adiabatically expands the liquid-phase refrigerant to reduce its pressure. The air heat exchanger 54, the compressor 62, the three-fluid heat exchanger 58, and the expansion valve 60 constitute the heat pump 50.

[0024] In the heat pump 50, the high-temperature, high-pressure gas-phase refrigerant delivered from the compressor 62 flows into the three-fluid heat exchanger 58. As the refrigerant passes through the three-fluid heat exchanger 58, it releases heat and condenses, becoming a liquid. The liquid-phase refrigerant that has passed through the three-fluid heat exchanger 58 is depressurized by the expansion valve 60. The low-temperature, low-pressure liquid-phase refrigerant that has passed through the expansion valve 60 flows into the air heat exchanger 54. As the refrigerant passes through the air heat exchanger 54, it absorbs heat and evaporates, becoming a gas-phase refrigerant. The gas-phase refrigerant that has passed through the air heat exchanger 54 is returned to the compressor 62. In the heat pump 50, the air heat exchanger 54 absorbs heat from the outside air, and the three-fluid heat exchanger 58 heats water and / or heating water.

[0025] The HP unit 6 includes an HP controller 102. The HP controller 102 includes a CPU, a ROM, a RAM, etc. Various operating programs are stored in the ROM. Various signals input to the HP controller 102 and various data generated in the process of the CPU executing processing are temporarily stored in the RAM. The HP controller 102 controls each component of the HP unit 6 by the CPU executing processing based on the information stored in the ROM and RAM.

[0026] (Tank unit 4 configuration) The tank unit 4 includes a hot water storage tank 10. The hot water storage tank 10 stores water heated by the HP unit 6. In this embodiment, the water stored in the hot water storage tank 10 is tap water. Water is stored in the hot water storage tank 10 until it is full. Thermistors 12, 14, 16, and 18 are attached to the hot water storage tank 10 at approximately equal intervals along the height of the hot water storage tank 10. Each of the thermistors 12, 14, 16, and 18 measures the temperature of the water at its attachment position.

[0027] The upstream end of the tank circulation path 20 is connected to the bottom of the hot water storage tank 10, passes through a three-fluid heat exchanger 58 of the HP unit 6, and has a downstream end connected to the top of the hot water storage tank 10. A tank circulation pump 22 is provided in the tank circulation path 20. The tank circulation pump 22 pumps water in the tank circulation path 20 from the upstream side to the downstream side. When the HP unit 6 drives the heat pump 50 and the tank circulation pump 22, water in the bottom of the hot water storage tank 10 is sent to the three-fluid heat exchanger 58 and heated, and the heated water is returned to the top of the hot water storage tank 10. As a result, temperature stratification is formed inside the hot water storage tank 10, with a layer of high-temperature water stacked on top of a layer of low-temperature water.

[0028] The upstream end of tap water inlet passage 24 is connected to tap water supply source 32 outside facility equipment 2. The downstream end of tap water inlet passage 24 branches into first inlet passage 24a and second inlet passage 24b. The downstream end of first inlet passage 24a is connected to the bottom of hot water storage tank 10. The downstream end of second inlet passage 24b is connected midway to first hot water supply passage 36. A check valve 26 is provided in first inlet passage 24a. A check valve 28 is provided in second inlet passage 24b.

[0029] The upstream end of the first hot water supply passage 36 is connected to the top of the hot water storage tank 10. As described above, the second inlet passage 24b of the tap water inlet passage 24 is connected to the first hot water supply passage 36. A mixing valve 30 is provided at the connection between the first hot water supply passage 36 and the second inlet passage 24b. The mixing valve 30 adjusts the ratio of the flow rate of high-temperature water flowing into the first hot water supply passage 36 from the top of the hot water storage tank 10 to the flow rate of low-temperature water flowing into the first hot water supply passage 36 from the second inlet passage 24b. The first hot water supply passage 36 downstream of the connection with the second inlet passage 24b passes through a hot water heating passage 37 of the combustion unit 8 and is connected to a second hot water supply passage 39. The first hot water supply passage 36 and the second hot water supply passage 39 are connected by a heat source machine bypass passage 33. A bypass valve 34 is provided in the heat source machine bypass passage 33. The downstream end of the second hot water supply passage 39 is connected to a hot water tap 38.

[0030] The tank unit 4 further includes a first heating water return conduit 84, a regulating valve 90, an HP circulation conduit 88, and an HP bypass conduit 94. Heating water flows into the first heating water return conduit 84 from the combustion unit 8, which will be described later. The downstream end of the first heating water return conduit 84 is connected to the regulating valve 90. The HP circulation conduit 88 and the HP bypass conduit 94 are further connected to the regulating valve 90. By changing the opening of the regulating valve 90, the ratio of the flow rate of heating water flowing from the first heating water return conduit 84 to the HP circulation conduit 88 to the flow rate of heating water flowing from the first heating water return conduit 84 to the HP bypass conduit 94 can be changed. The HP circulation conduit 88 passes through the three-fluid heat exchanger 58 of the HP unit 6 and is connected to the upstream end of the second heating water return conduit 96 of the combustion unit 8. The HP bypass conduit 94 is connected to the upstream end of the second heating water return conduit 96 without passing through the HP unit 6.

[0031] The tank unit 4 includes a tank controller 104. The tank controller 104 includes a CPU, a ROM, a RAM, etc. Various operating programs are stored in the ROM. Various signals input to the tank controller 104 and various data generated in the process of the CPU executing processing are temporarily stored in the RAM. The tank controller 104 controls each component of the tank unit 4 by the CPU executing processing based on the information stored in the ROM and RAM.

[0032] (Configuration of combustion unit 8) The combustion unit 8 includes a cistern 70, a hot water heating burner 81, and a heating water heating burner 82. The cistern 70 is a container with an open top that stores heating water inside. In this embodiment, the heating water is, for example, antifreeze. The downstream end of a second heating water return line 96 and the upstream end of a heating water outflow line 72 are connected to the cistern 70. A heating water circulation pump 74 is provided in the heating water outflow line 72. When the heating water circulation pump 74 is driven, the heating water in the cistern 70 flows into the heating water outflow line 72.

[0033] The downstream end of the heating water supply path 72 branches into a burner heating path 73, a low-temperature heating circulation path 75, and a low-temperature heating bypass path 85. A low-temperature heating terminal 78 is attached to the low-temperature heating circulation path 75. In this embodiment, the low-temperature heating terminal 78 is, for example, a floor heating panel installed in a living room. The low-temperature heating terminal 78 provides heating by heat radiation from the heating water. A first on-off valve 86 is provided in the low-temperature heating circulation path 75. A second on-off valve 87 is provided in the low-temperature heating bypass path 85.

[0034] A heating water heating burner 82 is provided in the burner heating path 73. The heating water heating burner 82 burns fuel (e.g., fuel gas) supplied from a fuel supply source (e.g., a gas conduit) to heat the heating water in the burner heating path 73. A fan 82a is attached to the heating water heating burner 82 to supply air to the heating water heating burner 82. The downstream end of the burner heating path 73 branches into a high-temperature heating circulation path 77, a high-temperature heating bypass path 71, and a reheating circulation path 79. A high-temperature heating terminal 76 is attached to the high-temperature heating circulation path 77. The high-temperature heating terminal 76 in this embodiment is, for example, a bathroom heater / dryer installed in a bathroom. The high-temperature heating terminal 76 provides heating by radiating heat from the heating water. A third on-off valve 89 is provided in the high-temperature heating circulation path 77. The low-temperature heating circulation path 75, the low-temperature heating bypass path 85, and the high-temperature heating circulation path 77 join at their respective downstream ends and connect to the upstream end of the first heating water return path 84 of the tank unit 4. A fourth on-off valve 80 is provided in the high-temperature heating bypass path 71. The downstream end of the high-temperature heating bypass path 71 is connected to the second heating water return path 96.

[0035] Reheating circulation path 79 is provided with a reheating thermal valve 83 and a reheating heat exchanger 97. Reheating thermal valve 83 opens and closes reheating circulation path 79. In reheating heat exchanger 97, heat is exchanged between the heating water flowing through reheating circulation path 79 and the water flowing through bathtub water circulation path 91. The downstream end of reheating circulation path 79 is connected to a second heating water return path 96.

[0036] One end and the other end of the bathtub water circulation path 91 communicate with the interior of the bathtub 130 via a bathtub adapter 132 provided at the bottom of the side of the bathtub 130. A bathtub water circulation pump 99 is provided in the bathtub water circulation path 91. When the bathtub water circulation pump 99 is driven, the water stored in the bathtub 130 (also called bathtub water) flows into one end of the bathtub water circulation path 91 via the bathtub adapter 132. Then, the water inside the bathtub water circulation path 91 flows out from the other end of the bathtub water circulation path 91 via the bathtub adapter 132 into the bathtub 130.

[0037] A hot water supply water heating burner 81 is provided in the hot water supply heating path 37. The hot water supply water heating burner 81 burns fuel (e.g., fuel gas) supplied from a fuel supply source (e.g., a gas conduit) to heat the water in the hot water supply heating path 37. A fan 81a is attached to the hot water supply water heating burner 81 to supply air to the hot water supply water heating burner 81. The downstream end of the hot water supply heating path 37 branches into a second hot water supply path 39 and a third hot water supply path 40. A bathtub hot water valve 42 that opens and closes the third hot water supply path 40 is provided in the third hot water supply path 40. The downstream end of the third hot water supply path 40 is connected to a portion of the bathtub water circulation path 91 between the bathtub water circulation pump 99 and the bathtub adapter 132.

[0038] The combustion unit 8 is equipped with a combustion controller 106. The combustion controller 106 is equipped with a CPU, ROM, RAM, etc. Various operating programs are stored in the ROM. Various signals input to the combustion controller 106 and various data generated in the process of the CPU executing processing are temporarily stored in the RAM. The combustion controller 106 controls each component of the combustion unit 8 by the CPU executing processing based on the information stored in the ROM and RAM.

[0039] A drain channel 131 is connected to the bottom of bathtub 130. Drain channel 131 is provided with a drain plug 133 that is manually opened and closed by the user. Drain plug 133 is normally closed. When bathtub water is stored in bathtub 130 and the user opens drain plug 133, the bathwater is discharged from bathtub 130 into drain channel 131. Bathtub 130 is provided with a drain plug open / close sensor 134 (see upper left in Figure 2) that can detect the open / close state of drain plug 133. Drain plug open / close sensor 134 outputs a signal indicating the open / close state of drain plug 133 to combustion controller 106. Drain plug 133 may also be an automatic drain plug that can be opened and closed automatically by combustion controller 106.

[0040] A bathtub lid 135 is provided on top of bathtub 130, which can be opened and closed manually by the user. Bathtub lid 135 is normally left open. When bathtub water is stored in bathtub 130, the user can close bathtub lid 135 to prevent the temperature of the bathtub water from dropping due to heat dissipation into the atmosphere. Bathtub 130 is provided with a bathtub lid open / close sensor 136 (see upper left of Figure 2) that can detect the open / close state of bathtub lid 135. Bathtub lid open / close sensor 136 outputs a signal indicating the open / close state of bathtub lid 135 to combustion controller 106.

[0041] A door open / close sensor 122 (see the upper left of FIG. 2) that can detect whether a door is open or closed, and a window open / close sensor 124 (see the upper left of FIG. 2) that can detect whether a window is open or closed, are provided in a room (e.g., a living room) in which the low-temperature heating terminal 78 is installed. The door open / close sensor 122 outputs a signal indicating whether the door is open or closed to the combustion controller 106. The window open / close sensor 124 outputs a signal indicating whether the window is open or closed to the combustion controller 106.

[0042] (Configuration of controller 110) The HP controller 102 and the tank controller 104 are capable of bidirectional communication. Furthermore, the tank controller 104 and the combustion controller 106 are capable of bidirectional communication. The HP controller 102, the tank controller 104, and the combustion controller 106 cooperate to control the facility equipment 2. In this specification, the HP controller 102, the tank controller 104, and the combustion controller 106 are also collectively referred to as the controller 110. The controller 110 is configured to be able to perform the following operations: boiling operation, low-temperature heating operation, high-temperature heating operation, hot water supply operation, water filling operation, cold water filling operation, and reheating operation, which will be described later.

[0043] Furthermore, the controller 110 (specifically, the tank controller 104) can communicate bidirectionally with a remote control 112 that can be operated by the user. The user can use the remote control 112 to give instructions to start or stop various operations and change various settings. The various settings referred to here include, for example, the set temperature for the water heating operation, the set temperature for the low-temperature heating operation, the set temperature for the high-temperature heating operation, the set temperature for the hot water supply operation, the set temperature and set water volume for the water filling operation, the set water volume for the water filling operation, and the set temperature for the reheating operation.

[0044] (Heating operation) The boiling operation is an operation in which the water in the hot water storage tank 10 is heated by the HP unit 6 and the high-temperature water is returned to the hot water storage tank 10. For example, when the temperature of the water in the hot water storage tank 10 (for example, the temperature detected by the thermistor 12) falls below a predetermined lower limit temperature, the controller 110 automatically starts the boiling operation. When the boiling operation is started, the controller 110 drives the compressor 62, the fan 56, and the tank circulation pump 22.

[0045] By driving the compressor 62, the refrigerant in the refrigerant circulation path 52 circulates through the compressor 62, the three-fluid heat exchanger 58, the expansion valve 60, and the air heat exchanger 54 in this order. In this case, the refrigerant in the refrigerant circulation path 52 passing through the three-fluid heat exchanger 58 is in a high-temperature, high-pressure gas phase. Furthermore, by driving the tank circulation pump 22, water in the hot water storage tank 10 circulates through the tank circulation path 20. That is, water present in the lower part of the hot water storage tank 10 is introduced into the tank circulation path 20. As the introduced water passes through the three-fluid heat exchanger 58, it is heated by the heat of the refrigerant in the refrigerant circulation path 52, and the heated water is returned to the upper part of the hot water storage tank 10. At this time, the controller 110 controls the compressor 62, the fan 56, and the tank circulation pump 22 so that the temperature of the water after passing through the three-fluid heat exchanger 58 becomes the set temperature for the boiling operation. As a result, high-temperature water is stored in the hot water storage tank 10. When the hot water storage tank 10 is filled with high-temperature water, the controller 110 stops the compressor 62, the fan 56, and the tank circulation pump 22, thereby ending the boiling operation.

[0046] (Low temperature heating operation) Low-temperature heating operation is an operation in which a room is heated using the low-temperature heating terminal 78. When the controller 110 receives an instruction to perform low-temperature heating operation from the remote control 112, it opens the first on-off valve 86 and drives the heating water circulation pump 74 while closing the second on-off valve 87, the third on-off valve 89, the fourth on-off valve 80, and the reheating thermal valve 83. Furthermore, the controller 110 drives the compressor 62 and the fan 56. As a result, the refrigerant in the refrigerant circulation path 52 is pressurized by the compressor 62 and becomes a high-temperature, high-pressure gas phase. The heating water heated while passing through the three-fluid heat exchanger 58 is then supplied to the low-temperature heating terminal 78 via the cistern 70. Furthermore, the controller 110 opens the fourth on-off valve 80 as necessary and drives the heating water heating burner 82 and the fan 82a. As a result, the heating water, which has been heated to a higher temperature by the heating water heating burner 82, is supplied to the low-temperature heating terminal 78 via the cistern 70. During low-temperature heating operation, the controller 110 specifies the target temperature (low-temperature target temperature) of the heating water to be supplied to the low-temperature heating terminal 78 based on the set temperature for the low-temperature heating operation. The controller 110 then controls the opening of the regulating valve 90, the operation of the HP unit 6, and the outputs of the heating water circulation pump 74, the heating water heating burner 82, and the fan 82a so that the temperature of the heating water supplied to the low-temperature heating terminal 78 becomes the low-temperature target temperature. When the controller 110 receives an instruction to end the low-temperature heating operation from the remote control 112, it stops the heating water circulation pump 74, the compressor 62, the fan 56, the heating water heating burner 82, and the fan 82a, and ends the low-temperature heating operation.

[0047] (High temperature heating operation) High-temperature heating operation is an operation in which the bathroom is heated using the high-temperature heating terminal 76. When controller 110 receives an instruction to perform high-temperature heating operation from remote control 112, it opens third on-off valve 89, closes first on-off valve 86, second on-off valve 87, and fourth on-off valve 80, and drives heating water circulation pump 74 with adjustment valve 90 fully closed on the HP circulation path 88 side and fully open on the HP bypass path 94 side. Furthermore, controller 110 drives heating water heating burner 82 and fan 82a. As a result, heating water heated to a high temperature by heating in heating water heating burner 82 is supplied to high-temperature heating terminal 76. During high-temperature heating operation, controller 110 determines the target temperature (high-temperature target temperature) of heating water to be supplied to high-temperature heating terminal 76 based on the set temperature for high-temperature heating operation. Then, controller 110 controls the outputs of heating water circulation pump 74, heating water heating burner 82, and fan 82a so that the temperature of the heating water supplied to high-temperature heating terminal 76 becomes the high-temperature target temperature. When controller 110 receives an instruction to end high-temperature heating operation from remote control 112, it stops heating water circulation pump 74, heating water heating burner 82, and fan 82a, and ends high-temperature heating operation.

[0048] When controller 110 receives both an instruction to perform low-temperature heating operation and an instruction to perform high-temperature heating operation from remote control 112, it performs operations substantially similar to the high-temperature heating operation described above. In this case, controller 110 performs the high-temperature heating operation described above with not only third on-off valve 89 but also first on-off valve 86 open. As a result, heating water that has been heated to a high temperature by heating in heating water heating burner 82 is supplied to high-temperature heating terminal 76, and heating water that has been slightly cooled by heat radiation from high-temperature heating terminal 76 is supplied to low-temperature heating terminal 78 via cistern 70.

[0049] (Hot water operation) The hot water supply operation is an operation in which water adjusted to a set temperature for the hot water supply operation is supplied to the hot water tap 38. When the hot water tap 38 is opened, the controller 110 starts the hot water supply operation. When the hot water tap 38 is opened, water pressure from the tap water supply source 32 causes tap water to flow from the tap water inlet path 24 (first inlet path 24a) into the lower part of the hot water storage tank 10. At the same time, water from the upper part of the hot water storage tank 10 is supplied to the hot water tap 38 via the first hot water supply path 36. In the hot water supply operation, if the temperature of the water supplied from the hot water storage tank 10 to the first hot water supply path 36 (i.e., the temperature detected by the thermistor 12) is higher than the set temperature, the controller 110 drives the mixing valve 30 to introduce tap water from the second inlet path 24b into the first hot water supply path 36. As a result, the water supplied from the hot water storage tank 10 and the tap water supplied from the second inlet path 24b are mixed in the first hot water supply path 36. In this case, the controller 110 adjusts the opening of the mixing valve 30 so that the temperature of the water supplied to the hot water tap 38 matches the set temperature. On the other hand, when the temperature of the water supplied from the hot water storage tank 10 to the first hot water supply path 36 is lower than the set temperature, the controller 110 closes the bypass valve 34 and heats the water passing through the first hot water supply path 36 by the hot water supply water heating burner 81 and the fan 81a. The controller 110 adjusts the output of the hot water supply water heating burner 81 and the fan 81a so that the temperature of the water supplied to the hot water tap 38 matches the set temperature. When the hot water tap 38 is closed, the controller 110 ends the hot water supply operation.

[0050] (Bath filling operation) The bath filling operation is an operation in which water adjusted to the set temperature for the bath filling operation is supplied to the bathtub 130 in the amount set for the bath filling operation. When the controller 110 receives an instruction to perform the bath filling operation from the remote control 112, it starts the bath filling operation. When the bath filling operation starts, the controller 110 opens the bathtub hot water valve 42. When the bathtub hot water valve 42 is opened, water pressure from the bath water supply source 32 causes tap water to flow from the tap water inlet path 24 (first inlet path 24a) into the bottom of the hot water storage tank 10. At the same time, water from the top of the hot water storage tank 10 flows into the bathtub 130 via the first hot water supply path 36, the hot water supply heating path 37, the third hot water supply path 40, the bathtub water circulation path 91, and the bathtub adapter 132. In the bath filling operation, the temperature of the water supplied to the third hot water supply path 40 is adjusted to the set temperature in the same way as in the hot water supply operation. When the flow rate of water supplied to the bathtub 130 reaches the set water volume, the controller 110 closes the bathtub hot water supply valve 42 and ends the bath filling operation.

[0051] (Water filling operation) The water filling operation is an operation in which unheated tap water is supplied to the bathtub 130 in the amount set for the water filling operation. When the controller 110 receives an instruction to perform the water filling operation from the remote control 112, it starts the water filling operation. When the water filling operation starts, the controller 110 controls the mixing valve 30 so that the hot water storage tank 10 side is fully closed and the second inlet path 24b side is fully open, and opens the bathtub hot water valve 42. As a result, water pressure from the tap water supply source 32 causes tap water to flow from the tap water inlet path 24 (second inlet path 24b) through the first hot water supply path 36, the hot water supply heating path 37, the third hot water supply path 40, the bathtub water circulation path 91, and the bathtub adapter 132 into the bathtub 130. Unlike the bath filling operation, heating by the hot water supply heating burner 81 is not performed during the water filling operation. When the flow rate of water supplied to the bathtub 130 reaches the set water volume, the controller 110 closes the bathtub hot water supply valve 42 and ends the water filling operation.

[0052] (Reheating operation) Reheating operation is an operation for reheating bathwater. When controller 110 receives a command to perform reheating operation from remote control 112, it starts the reheating operation. In reheating operation, controller 110 closes first on-off valve 86, second on-off valve 87, third on-off valve 89, and fourth on-off valve 80, opens reheating thermal valve 83, and drives heating water circulation pump 74 with adjustment valve 90 fully closed on the HP circulation path 88 side and fully open on the HP bypass path 94 side. In reheating operation, heating water is heated by heating water heating burner 82, just as in high-temperature heating operation. Controller 110 also drives bathwater circulation pump 99. This causes bathwater to flow into bathwater circulation path 91 via bathtub adapter 132 and be sent to reheating heat exchanger 97. In reheating heat exchanger 97, the water flowing through bathtub water circulation path 91 is heated by the heat of the heating water flowing through reheating circulation path 79. The bathtub water heated in reheating heat exchanger 97 is returned to bathtub 130 via bathtub water circulation path 91 and bathtub adapter 132. When the temperature of the bathtub water flowing into bathtub water circulation path 91 from bathtub 130 exceeds the set temperature for reheating operation, controller 110 stops heating of the heating water by heating water heating burner 82 and stops bathtub water circulation pump 99 and heating water circulation pump 74, thereby ending reheating operation.

[0053] (Internet connection for Equipment 2) The remote control 112 can communicate with a router device (not shown) installed in the home via wireless communication. The controller 110 (specifically, the tank controller 104) can connect to the Internet via the remote control 112 and the router device. This allows the controller 110 to communicate with the server device 210 via the Internet.

[0054] (Configuration of server device 210) 1 is, for example, a stationary server device managed by a manufacturer of the equipment 2. The server device 210 includes a control unit (not shown) including a CPU, ROM, RAM, etc., a storage unit (not shown) including an HDD, SSD, etc., and a communication unit (not shown) connectable to the Internet. The server device 210 stores information such as the location information of the residence in which the equipment 2 is installed and identification information of the terminal device 220 owned by the user of the equipment 2.

[0055] (Configuration of terminal device 220) The terminal device 220 is, for example, a portable or stationary communication terminal (e.g., a smartphone, mobile phone, tablet, PC, etc.) owned by a user of the facility equipment 2. The terminal device 220 includes a control unit (not shown) including a CPU, ROM, RAM, etc., a display unit (not shown) such as a display, an input unit (not shown) such as a touch switch, a storage unit (not shown) including an EEPROM, flash memory, etc., and a communication unit (not shown) connectable to the Internet. The terminal device 220 is capable of communicating with the controller 110 of the facility equipment 2 via the server device 210.

[0056] (Configuration of external server device 300) The external server device 300 is, for example, a stationary server device managed by a company that provides weather information. The external server device 300 includes a control unit (not shown) including a CPU, ROM, RAM, etc., a storage unit (not shown) including a HDD, SSD, etc., and a communication unit (not shown) connectable to the Internet. The external server device 300 provides weather information for various parts of the country and power outage prediction information based on the weather information. The power outage prediction information may be, for example, information indicating the probability of a power outage occurring for each predetermined time period (for example, every hour) from the current time until a predetermined period (for example, 72 hours later) expressed in multiple levels (for example, four levels) for each predetermined area (for example, for each 5-kilometer square area). Alternatively, when a power company or the like implements planned power outages, the power outage prediction information may be information indicating the scheduled start time and end time of the power outage for each predetermined area (for example, for each 5-kilometer square area).

[0057] The server device 210 can acquire power outage prediction information for the residence in which the facility device 2 is installed, based on power outage prediction information for all parts of the country provided from the external server device 300 via the Internet and location information of the residence in which the facility device 2 is installed. Upon acquiring the power outage prediction information for the residence in which the facility device 2 is installed, the server device 210 transmits the power outage prediction information to the controller 110 of the facility device 2.

[0058] (Example of power outage prevention operation) When controller 110 acquires power outage prediction information from server device 210, it executes the process shown in Fig. 3. Note that the process shown in Fig. 3 assumes that drain plug 133 is a manual drain plug that is opened and closed manually by a user.

[0059] In S2, the controller 110 identifies, based on the power outage prediction information, the time at which a power outage is predicted to occur in the residence where the equipment 2 is installed, as the predicted power outage time. For example, if the power outage prediction information is information that indicates, for each predetermined area (for example, for each 5-km square area), values ​​that represent the possibility of a power outage for each predetermined time period (for example, every hour) from the current time until a predetermined period (for example, 72 hours later) using multiple levels (for example, four levels), the information indicates the possibility of a power outage for each predetermined area (for example, for each 5-km square area), the controller 110 identifies, as the predicted power outage time, the time at which the possibility of a power outage will reach the highest level (for example, the fourth level) in the residence where the equipment 2 is installed. Alternatively, if the power outage prediction information is information that indicates, for each predetermined area (for example, for each 5-km square area), the time at which a power outage is scheduled to start and the time at which the power outage is scheduled to end, the controller 110 identifies, as the predicted power outage time, the time at which a power outage is scheduled to start in the residence where the equipment 2 is installed. Note that the server device 210, rather than the controller 110, may identify the predicted power outage time. In this case, in S2, the controller 110 acquires from the server device 210 the predicted power outage time that the server device 210 has identified based on the power outage prediction information.

[0060] In S4, the controller 110 identifies a first time and a second time. The first time is a first predetermined time (e.g., one hour) before the predicted power outage time. The second time is a second predetermined time (e.g., two hours) before the predicted power outage time. The second predetermined time is set to be longer than the first predetermined time.

[0061] In S6, the controller 110 determines whether the current time has passed the second time. If the current time has not passed the second time (NO), the process returns to S6. If the current time has passed the second time (YES), the process proceeds to S8.

[0062] In S8, controller 110 executes a notification to prompt the user to perform a preliminary action corresponding to the power outage countermeasure operation. In the example of FIG. 3, the power outage countermeasure operation is the execution of an operation to fill bathtub 130 with water, and the preliminary action is the action of closing drain plug 133 of bathtub 130. That is, in S8, controller 110 executes a notification to terminal device 204 to prompt the user to close drain plug 133. As a result, a notification prompting the user to close drain plug 133 is displayed on terminal device 204 carried by the user. Note that the action of closing drain plug 133 of bathtub 130 corresponds to the preparatory action required for the power outage countermeasure operation of filling bathtub 130 with water.

[0063] In S10, controller 110 determines whether the preliminary action notified in S8 has been performed. In the example of Fig. 3, controller 110 determines whether drain plug 133 has been closed based on a detection signal from drain plug open / close sensor 134. If drain plug 133 has not been closed (NO), the process returns to S10. If drain plug 133 has been closed (YES), the process proceeds to S12.

[0064] In S12, the controller 110 determines whether the current time has passed the first time. If the current time has not passed the first time (NO), the process returns to S12. If the current time has passed the first time (YES), the process proceeds to S14.

[0065] In S14, controller 110 executes power outage countermeasure operation. In the example of Fig. 3, controller 110 executes an operation to fill bathtub 130. This allows high-temperature bathwater to be stored in bathtub 130 before a power outage occurs. After S14, the processing of Fig. 3 ends.

[0066] In the example of Figure 3, before performing the water filling operation as a power outage countermeasure operation in S14, the user performs a preliminary action of closing the drain plug 133, thereby preventing the water filling operation from being performed when the drain plug 133 is not closed.

[0067] (Another example of power outage prevention operation) When controller 110 acquires power outage prediction information from external server device 300, it may execute the process shown in Figure 4 instead of the process shown in Figure 3. In the process shown in Figure 4, the power outage countermeasure operation is the execution of a water filling operation for bathtub 130, and the preliminary action is the action of closing bathtub lid 135 for bathtub 130. In this case, the action of closing bathtub lid 135 for bathtub 130 corresponds to an auxiliary action for further enhancing the effectiveness of the water filling operation for bathtub 130, which is the power outage countermeasure operation. In addition, the process shown in Figure 4 assumes that drain plug 133 is not a manual drain plug that is opened and closed manually by the user, but an automatic drain plug that is opened and closed automatically by controller 110. In this case, controller 110 automatically executes the process of closing drain plug 133 when executing a water filling operation, so the user does not need to perform the action of closing drain plug 133.

[0068] Since steps S2 to S6 are the same as the processes shown in FIG. 3, the description thereof will be omitted.

[0069] In S22, controller 110 executes a notification to terminal device 204 urging the user to close bathtub lid 135. As a result, a notification urging the user to close bathtub lid 135 is displayed on terminal device 204 carried by the user.

[0070] In S24, controller 110 determines whether bathtub lid 135 is closed based on the detection signal from bathtub lid open / close sensor 136. If bathtub lid 135 is not closed (NO), processing returns to S24. If bathtub lid 135 is closed (YES), processing proceeds to S12.

[0071] Explanation of S12 and S14 will be omitted as they are the same as the processes shown in Fig. 3. After S14, the process in Fig. 4 ends.

[0072] In the example of Figure 4, before performing the water filling operation as a power outage countermeasure operation in S14, the user performs a preliminary action of closing the bathtub lid 135, thereby preventing the water filling operation from being performed when the bathtub lid 135 is not closed.

[0073] In the process shown in Fig. 4, drain plug 133 may be a manual drain plug that is opened and closed manually by the user. In this case, in S22 of Fig. 4, controller 110 may execute a notification prompting both the operation of closing drain plug 133 and the operation of closing bathtub lid 135 as a preliminary operation. In this case, the process may proceed to S12 if, in S24, a detection signal from drain plug open / close sensor 134 determines that drain plug 133 is closed, and a detection signal from bathtub lid open / close sensor 136 determines that bathtub lid 135 is closed. This configuration makes it possible to prevent the bathtub filling operation from being performed when drain plug 133 or bathtub lid 135 is not closed.

[0074] (Yet another example of power outage prevention operation) When controller 110 acquires power outage prediction information from external server device 300, it may execute the process shown in Fig. 5 instead of the process shown in Fig. 3. In the process shown in Fig. 5, the power outage countermeasure operation is the operation of filling bathtub 130 with water, and the preliminary operation is the operation of closing drain plug 133 of bathtub 130. The operation of closing drain plug 133 of bathtub 130 corresponds to the preparatory operation required for the power outage countermeasure operation of filling bathtub 130 with water. In addition, the process shown in Fig. 5 assumes that drain plug 133 is a manual drain plug that is opened and closed manually by the user.

[0075] Since S2 to S8 are the same as the processes shown in FIG. 3, the description thereof will be omitted.

[0076] In S32, controller 110 determines whether or not permission to perform water filling operation has been received from terminal device 204. In the example shown in FIG. 5, after a notification prompting the user to close drain plug 133 of bathtub 130 is displayed on terminal device 204, the user can input permission to perform subsequent water filling operation via terminal device 204. Therefore, after the user closes drain plug 133 of bathtub 130, the user can input permission to perform subsequent water filling operation via terminal device 204, thereby permitting the execution of subsequent water filling operation. If permission to perform water filling operation is not received in S32 (NO), the process returns to S32. If permission to perform water filling operation is received (YES), the process proceeds to S12.

[0077] Since S12 is the same as the process shown in FIG. 3, the description thereof will be omitted.

[0078] In S34, controller 110 executes a water filling operation for bathtub 130. This allows bathwater to be stored in bathtub 130 before a power outage occurs. After S34, the processing in FIG. 5 ends.

[0079] In the example of Figure 5, before performing the water filling operation as a power outage prevention operation in S34, the user performs a preliminary action of closing the drain plug 133, thereby preventing the water filling operation from being performed when the drain plug 133 is not closed.

[0080] (Yet another example of power outage prevention operation) When controller 110 acquires power outage prediction information from external server device 300, it may execute the process shown in Fig. 6 instead of the process shown in Fig. 3. In the process shown in Fig. 6, the power outage countermeasure operation is room heating operation using low-temperature heating terminal 78, and the preparatory actions are the action of closing the room door and the action of closing the room window. In this case, the action of closing the room door and the action of closing the room window both correspond to auxiliary actions for further enhancing the effect of the room heating operation, which is the power outage countermeasure operation.

[0081] Since S2 to S6 are the same as the processes shown in FIG. 3, the description thereof will be omitted.

[0082] In S42, the controller 110 executes a notification to prompt the user to close the door and the window of the living room to the terminal device 204. As a result, a notification prompting the user to close the door and the window of the living room is displayed on the terminal device 204 carried by the user.

[0083] In S44, controller 110 determines whether the door to the living room is closed based on a detection signal from door open / close sensor 122. If the door to the living room is not closed (NO), the process returns to S44. If the door to the living room is closed (YES), the process proceeds to S46.

[0084] In S46, the controller 110 determines whether the window in the living room is closed based on the detection signal from the window open / close sensor 124. If the window in the living room is not closed (NO), the process returns to S46. If the window in the living room is closed (YES), the process proceeds to S12.

[0085] Since S12 is the same as the process shown in FIG. 3, the description thereof will be omitted.

[0086] In S48, controller 110 executes heating operation for the room using low-temperature heating terminal 78. This allows the room to be heated before a power outage occurs. After S48, the processing in FIG. 6 ends.

[0087] In the example of Figure 6, before performing heating operation in the room as a power outage prevention operation in S48, the user performs preparatory actions of closing the door and window of the room, thereby preventing heating operation in the room from being performed when the door or window of the room is not closed.

[0088] (Yet another example of power outage prevention operation) When controller 110 acquires power outage prediction information from external server device 300, it may execute the process shown in Fig. 7 instead of the process shown in Fig. 3. In the process shown in Fig. 7, the power outage countermeasure operation is the operation of heating up hot water storage tank 10, and the preparatory operation is the operation of washing dishes using high-temperature water in hot water storage tank 10. In this case, the operation of washing dishes using high-temperature water in hot water storage tank 10 corresponds to an auxiliary operation for further enhancing the effect of the operation of heating up hot water storage tank 10, which is the power outage countermeasure operation.

[0089] Since S2 to S6 are the same as the processes shown in FIG. 3, the description thereof will be omitted.

[0090] In S52, the controller 110 executes a notification to the terminal device 204 urging the user to wash dishes using the high-temperature water in the hot water storage tank 10. As a result, a notification urging the user to wash dishes is displayed on the terminal device 204 carried by the user.

[0091] In S54, controller 110 determines whether permission to perform the water heating operation has been received from terminal device 204. In the example shown in FIG. 7, after a notification prompting the user to wash dishes using high-temperature water from hot water storage tank 10 is displayed on terminal device 204, the user can input permission to perform the subsequent water heating operation via terminal device 204. Therefore, after the user washes dishes using high-temperature water from hot water storage tank 10, the user can input permission to perform the water heating operation via terminal device 204, thereby permitting the subsequent water heating operation to be performed. If permission to perform the water heating operation has not been received in S54 (NO), the process returns to S54. If permission to perform the water heating operation has been received (YES), the process proceeds to S12.

[0092] Since S12 is the same as the process shown in FIG. 3, the description thereof will be omitted.

[0093] In S56, the controller 110 executes the boiling operation. This allows high-temperature water to be stored in the hot water storage tank 10 before a power outage occurs. After S56, the processing in FIG. 7 ends.

[0094] 7, before the heating operation is performed as a power outage countermeasure operation in S56, the user performs a preliminary operation of washing dishes using high-temperature water in the hot water storage tank 10. This prevents the high-temperature water stored in the hot water storage tank 10 by the heating operation from being consumed by subsequent dishwashing.

[0095] (Correspondence) The server device 210 is an example of a "power outage prediction device," and the drain plug open / close sensor 134, the bathtub lid open / close sensor 136, the door open / close sensor 122, and the window open / close sensor 124 are examples of "sensors."

[0096] (Variation) A cooling device (not shown) may be provided in a room of the house in which the facility device 2 is installed, instead of the low-temperature heating terminal 78. In this case, in S48 of Fig. 6, the controller 110 may perform a cooling operation of the room using the cooling device, instead of a heating operation of the room using the low-temperature heating terminal 78, as a power outage countermeasure operation.

[0097] A storage battery (not shown) may also be provided in the home in which the facility device 2 is installed. In this case, in S56 of Fig. 7, the controller 110 may execute a charging operation from the commercial power grid to the storage battery as a power outage countermeasure operation instead of a heating operation of the hot water storage tank 10. In this case, the controller 110 may execute a notification to prompt the user to perform an operation that consumes power from the storage battery as a pre-operation in S52. With this configuration, it is possible to prevent the power stored in the storage battery by the charging operation from being subsequently consumed.

[0098] In the process of Fig. 3, a water filling operation may be performed instead of a hot water filling operation as a power outage countermeasure operation. Also, in the process of Fig. 5, a water filling operation may be performed instead of a cold water filling operation as a power outage countermeasure operation.

[0099] In the process of Fig. 6, the preliminary action corresponding to the heating operation in the room, which is the power outage countermeasure operation, may be only one of the actions of closing the door of the room and the window of the room. In this case, in S42 of Fig. 6, controller 110 may execute a notification prompting only one of the actions of closing the door of the room and the window of the room. Furthermore, of S44 and S46 of Fig. 6, controller 110 may execute only the process corresponding to the action notified in S42, and not execute the other process.

[0100] In the processing of Figure 6, as a power outage countermeasure operation, instead of heating the room using low-temperature heating terminal 78, bathroom heating operation using high-temperature heating terminal 76 may be performed. In this case, controller 110 may execute a notification prompting the user to close the bathroom door and bathroom window as a pre-action in S42 of Figure 6. Alternatively, door open / close sensor 122 and window open / close sensor 124 may be configured to be able to detect the open / closed states of the bathroom door and window, respectively, and controller 110 may determine whether the bathroom door is closed in S44 and whether the bathroom window is closed in S46.

[0101] In the processes of FIGS. 3, 4, 5, 6 and 7, steps S10, S24, S32, S44, S46 and S54 do not have to be executed.

[0102] The facility device 2 may also be equipped with another type of heating device, for example, a gas fan heater (not shown). In this case, the facility device 2 may perform heating operation using the gas fan heater as power outage countermeasure operation, and may notify the user to perform an operation to open the main valve (not shown) of a gas supply pipe (not shown) that supplies fuel gas to the gas fan heater as a preparatory operation for the power outage countermeasure operation. In this case, the operation of opening the main valve of the gas supply pipe corresponds to a preparatory operation required for heating operation using the gas fan heater, which is power outage countermeasure operation.

Furthermore, the technologies illustrated in this specification or drawings can achieve multiple objectives simultaneously, and achieving one of those objectives is itself technically useful.
