The present invention relates to a bathroom air conditioning system, a control device, a bathroom air conditioning method, and a program.

Especially in the winter, there is a demand for room temperature control in bathrooms that takes into consideration the user's health by suppressing the user's heat shock. On the other hand, it is connected in series to the forward side of the hot water supply path for supplying hot water from the bath water heater to the bathtub, and uses the heat transferred from the hot water supplied from the water heater to the bathtub to heat the floor of the bathroom. A bathroom floor heating device that performs heating has been proposed (see Patent Document 1, for example). According to the bathroom floor heating device described in Patent Literature 1, the user's feet are warmed, so the user's comfort is improved accordingly. However, it is difficult to warm the user's upper body by the radiant heat from the floor heating device installed on the floor of the washroom. Therefore, in order to suppress the user's heat shock, it is necessary to further heat the entire bathroom.

However, in many cases, the floor area of the washing place where the bathroom floor heating device is installed is small. In addition, since the floor of the washroom is directly touched by the user, the maximum temperature is also suppressed. For this reason, a certain amount of time is required to warm the entire bathroom, which may impair user convenience.

(Embodiment 1)
The bathroom air conditioning system according to the present embodiment includes a water heater, a first circulation pipe embedded in the floor of the bathroom and through which hot water supplied from the water heater circulates, and a wall of the bathroom where hot water is supplied from the water heater. and a second circulation pipe through which hot water is circulated. Here, the first circulation pipe and the second circulation pipe are arranged so that hot water supplied from the water heater flows through the first circulation pipe, then flows through the second circulation pipe, and then returns to the water heater. . Further, the bathroom air conditioning system according to the present embodiment includes a first temperature sensor that detects a first temperature of the floor, a second temperature sensor that detects a second temperature of the wall of the bathroom, the first temperature and the second temperature. 2 based on the temperature, first hot water supply start instruction information instructing the water heater to start supplying hot water to the first circulation pipe, or instructing the water heater to supply hot water to the first circulation pipe. and a control device that generates hot water supply suspension instruction information for instructing suspension.

The bathroom air conditioning system according to the present embodiment is installed in a bathroom R including a bathtub 3 and a faucet 4 as shown in FIG. 1, for example. This bathroom air conditioning system includes a water heater 2 for boiling hot water, a wall-embedded heat transfer panel 6 embedded in the wall WA of the bathroom R, and a floor-embedded heat transfer panel embedded in the floor FL of the washing area of the bathroom R. 5, the hot water discharged from the water heater 2 flows through the circulation path provided in the wall-embedded heat transfer panel 6 and the floor-embedded heat transfer panel 5, and heat is exchanged with the wall WA and the floor FL. The temperature of the air in the bathroom R is adjusted by warming the WA and the floor FL. The circulation path provided in the wall-embedded heat transfer panel 6 and the floor-embedded heat transfer panel 5 may be independent from the hot water supply path from the water heater 2 to the bathtub 3, the faucet 4, the kitchen (not shown), etc. . In this case, it is possible to reduce the influence of hot water supply from the water heater 2 to the wall-embedded heat transfer panel 6 and the floor-embedded heat transfer panel 5 on filling the bathtub with hot water, washing work in the kitchen, and the like. . This air conditioning system also includes a temperature sensor 71 that detects the temperature of the floor FL, a temperature sensor 72 that detects the temperature of the walls WA, an operation device 8 operated by a user, and operation details received by the operation device 8. and a control device 1 that controls the hot water heater 2 according to.

The water heater 2 heats tap water using electricity, gas, or the like as an energy source, and supplies hot water to a dwelling unit having a bathroom R. The water heater 2 may be a hot water storage type water heater having a hot water storage tank, or may be an instantaneous water heating type water heater. However, from the viewpoint of energy efficiency, the water heater 2 is preferably a hot water storage type water heater that can use a heat pump to boil hot water. If the water heater 2 is a hot water storage type water heater, for example, hot water boiled during the day is stored in a hot water storage tank in cooperation with a solar power generation system, and the hot water stored in the hot water storage tank is used at night. Therefore, it is preferable from the viewpoint of effective utilization of renewable energy. When the water heater 2 is a hot water storage type water heater, the temperature of the hot water stored in the hot water storage tank is maintained at a high temperature of 80° C. or higher. Then, the water heater 2 adjusts the temperature of the hot water by appropriately adding tap water having a lower temperature than the hot water stored in the hot water storage tank at the time of hot water supply. On the other hand, if the water heater 2 is an instantaneous water heater type water heater, the temperature of the hot water is adjusted by changing the degree of heating of the water that is the basis of the hot water.

Water heater 2 is also connected to circulation pipe 610 via hot water supply pipe 931 and to circulation pipe 510 via circulation pipe 951, as shown in FIG. Also, the water heater 2 is connected to a hot water supply path to other facilities in the dwelling unit such as a bathtub 3, a faucet 4 and a kitchen via a hot water supply pipe (not shown). Then, the water heater 2 supplies hot water to other facilities in the dwelling unit through the hot water supply pipe. Water heater 2 starts supplying hot water to circulation pipes 610 and 510 when hot water supply start instruction information is received from control device 1, and stops supplying hot water to circulation pipes 610 and 510 when hot water supply stop instruction information is received from control device 1. Pause temporarily. Further, when hot water supply temperature information is received from control device 1, water heater 2 adjusts the temperature of hot water supplied to circulation pipes 610 and 510 to the hot water supply temperature indicated by the hot water supply temperature information. Further, upon receiving the operation stop instruction information from the control device 1, the water heater 2 stops its operation. In this specification, temporarily stopping the hot water supply from the water heater 2 is referred to as "pause", and stopping the operation of the water heater 2 is referred to as "stop".

As shown in FIG. 2, the wall-embedded heat transfer panel 6 includes a circulation pipe 610 through which hot water supplied from the water heater 2 circulates, a heat transfer plate 612 for transferring heat from the circulation pipe 610 to the wall WA, have The heat transfer plate 612 has a rectangular plate shape and is made of metal with high thermal conductivity such as aluminum.

As shown in FIGS. 3A and 3B, the wall-embedded heat transfer panel 6 has a flat rectangular box-like shape as a whole, and the heat transfer plate 612 side is on the inside of the bathroom R. Embedded in WA. Further, the wall-embedded heat transfer panel 6 has a heat insulating material 616 arranged so as to cover the circulation pipe 610 side of the heat transfer plate 612 . As a result, heat dissipation from the heat transfer plate 612 to the side opposite to the inside of the bathroom R is suppressed. The circulation pipe 610 is formed in a tubular shape from metal with high thermal conductivity such as aluminum. The circulation pipe 610 is arranged on one surface side of the heat transfer plate 612 in the thickness direction, and is parallel to the long water conduit 613 along the longitudinal direction of the water conduit 613 and communicates with the water conduit 613 at one end. and a long drain pipe 614 communicating with the other end of each of the plurality of heat transfer tubes 615 . A hot water supply pipe 931 is connected to the water conduit 613 . Moreover, as shown in FIG. 3B, the heat insulating material 616 is not interposed between the heat transfer tube 615 and the heat transfer plate 612, and they are thermally coupled to each other.

Returning to FIG. 2, the floor-embedded heat transfer panel 5 has the same configuration as the wall-embedded heat transfer panel 6, and includes a circulation pipe 510 through which hot water supplied from the water heater 2 circulates, and a circulation pipe 510 to the floor FL. and a heat transfer plate 512 for transferring heat. The material and shape of heat transfer plate 512 and the material of circulation pipe 510 are similar to heat transfer plate 612 and circulation pipe 610 . Circulation pipe 510 is a first circulation pipe connected to wall-embedded heat transfer panel 6 via connection pipe 941 and to water heater 2 via circulation pipe 951 . The floor-embedded heat transfer panel 5 also has a flat rectangular box shape as a whole, and has a heat insulating member (not shown) disposed so as to cover the circulation pipe 510 side of the heat transfer plate 512 .

Here, the hot water supplied from the water heater 2 to the hot water supply pipe 931 flows through the circulation pipe 610 of the wall-embedded heat transfer panel 6, the connection pipe 941, the circulation pipe 510 of the floor-embedded heat transfer panel 5, and the circulation pipe 951 in this order. Return to water heater 2. That is, circulation pipes 610 and 510 are arranged so that hot water supplied from water heater 2 flows through circulation pipe 610 and then flows through circulation pipe 510 before returning to water heater 2 .

The temperature sensor 71 is a first temperature sensor embedded in the floor FL of the bathroom R. The temperature sensor 71 is arranged near the surface of the floor FL and not in contact with the heat transfer plate 512 of the floor-embedded heat transfer panel 5 . The temperature sensor 72 is a second temperature sensor embedded in the wall WA of the bathroom R. The temperature sensor 72 is located near the surface of the wall WA and not in contact with the heat transfer plate 612 of the wall-embedded heat transfer panel 6 .

The operating device 8 has, for example, a push switch 81 operated by a user and a display screen 82 for displaying the target temperature of the floor FL of the bathroom R or the time, as shown in FIG. 4 . This operation device 8 is installed on the wall WA of the bathroom R, for example, as shown in FIG. In the example shown in FIG. 4, the display screen 82 displays information IN1 indicating the current temperature of the floor FL, information IN2 indicating the current time, information IN3 indicating the target temperature of the floor FL set by the user, and a timer. Information IN4 indicating the time at which the will operate is displayed. By operating the push switch 81, the user can start or stop the operation of the bathroom air conditioning system, set the target temperature of the floor FL, or set the time at which the timer operates.

The control device 1 is installed at an appropriate place in the dwelling unit having the bathroom R, collects various inputs from the operation device 8 and the temperature sensors 71 and 72, and controls the operation of the water heater 2. As shown in FIG. 5, the control device 1 includes a CPU (Central Processing Unit) 101, a main memory section 102, an auxiliary memory section 103, a communication interface 104, and a bus 109 connecting these to each other. A main storage unit 102 is used as a work area for the CPU 101 . The auxiliary storage unit 103 is, for example, a non-volatile semiconductor memory such as flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), or HDD (Hard Disk Drive). Auxiliary storage unit 103 stores programs for CPU 101 to execute various processes. Communication interface 104 communicates with water heater 2 and temperature sensors 71 and 72 .

The CPU 101 reads the program stored in the auxiliary storage unit 103 into the main storage unit 102 and executes it to obtain a temperature acquisition unit 111, a determination unit 112, a temperature difference calculation unit 113, an instruction information generation unit 114, a transmission unit 115, a target It functions as a temperature updating unit 116 , a flag managing unit 117 and a timer unit 118 . Further, the auxiliary storage unit 103 includes a target temperature storage unit 131 for storing target temperature information indicating a preset target temperature for warming the floor FL, and a first reference temperature indicating a first reference temperature for the temperature of the floor FL. and a reference information storage unit 132 for storing information and second reference temperature information indicating a second reference temperature with respect to the temperature of the wall WA. The reference information storage unit 132 also stores target lower limit temperature information indicating the target lower limit temperature, which is the lower limit of the target temperature of the floor FL.

Here, the first reference temperature and the second reference temperature are set within a temperature range that does not cause so-called low-temperature burns even if the user keeps contact with the floor FL for 20 minutes, for example. In addition, the relationship between the temperature of the skin in contact with the floor FL and the time until the user's skin gets a low-temperature burn is, for example, 3 to 4 hours when the skin temperature is 44°C, and 30 minutes when the skin temperature is 46°C. It is reported that it takes 2 to 3 minutes at 50°C for 1 hour and 2 to 3 minutes (see Non-Patent Literature: Yukio Yamada, "Low Temperature Burns", Product Safety Association, "Products and Safety", No. 72). Therefore, the first reference temperature is set to 48°C, for example, and the second reference temperature is set to 50°C, for example. The first reference temperature is set lower than the second reference temperature because the floor FL is in contact with the user longer than the wall WA. Further, reference information storage unit 132 stores standby time information indicating a standby time after transmission of hot water supply start instruction information to water heater 2 . This standby time is set based on the time required for the temperature of the wall WA or the floor FL of the bathroom R to stabilize, and is set to, for example, about 3 to 5 minutes. The waiting time may be increased or decreased appropriately according to the size of the bathroom R or the environment in which the bathroom R is installed.

Further, the target temperature candidate storage unit 122 temporarily stores target temperature information input from the operation device 8 . Flag storage unit 121 stores flag information indicating whether target temperature information is stored in target temperature candidate storage unit 122 . This flag information is initially set to "F0" and updated to "F1" when the target temperature information input from the operation device 8 is newly stored in the target temperature candidate storage unit 122. FIG. Then, when the target temperature stored in the target temperature storage unit 131 is updated with the target temperature information stored in the target temperature candidate storage unit 122, the flag information is updated to "F0".

The temperature acquisition unit 111 acquires first temperature information indicating a first temperature, which is the temperature of the floor FL, from the temperature sensor 71, and second temperature information indicating a second temperature, which is the temperature of the wall WA, from the temperature sensor 72. get.

The timing unit 118 is, for example, a software down counter that updates the count value information for timing stored in the main storage unit 102 by decrementing it by "1" every preset unit time. Elapsed time from the start of bathroom air conditioning processing is counted. The unit time is set to an integral multiple of one period of a clock signal output from a clock generator (not shown) built in the control device 1, for example. Timing unit 118 sets count value information for timing stored in main storage unit 102 to a preset initial value at the same time when control device 1 starts bathroom air conditioning processing. Then, when the count value indicated by the count value information for timekeeping reaches “0”, timekeeping unit 118 notifies instruction information generation unit 114 of count-up information for forcibly stopping the operation of water heater 2 .

The determination unit 112 acquires the target temperature information stored in the target temperature storage unit 131 and determines whether or not the temperature of the floor FL is lower than the target temperature indicated by the acquired target temperature information. Further, the determination unit 112 acquires the first reference temperature information and the second reference temperature information stored in the reference information storage unit 132, and the temperature of the floor FL is less than the first reference temperature indicated by the acquired first reference temperature information. and the temperature of the wall WA is lower than the second reference temperature indicated by the acquired second reference temperature information. Furthermore, the determination unit 112 acquires the waiting time information from the reference information storage unit 132, and the elapsed time after the transmission unit 115 transmits the hot water supply start instruction information to the water heater 2 matches the waiting time indicated by the waiting time information. Determine whether or not Further, the determination unit 112 determines whether or not the temperature difference between the temperature of the floor FL and the aforementioned target temperature calculated by the temperature difference calculation unit 113 is higher than 0°C.

The temperature difference calculation unit 113 acquires the target temperature information stored in the target temperature storage unit 131, and calculates the first temperature of the floor FL indicated by the first temperature information acquired by the temperature acquisition unit 111 and the acquired target temperature information. Calculate the temperature difference from the target temperature. Specifically, the temperature difference calculator 113 calculates a value obtained by subtracting the first temperature from the target temperature. The temperature difference calculator 113 then takes the integer part of the calculated value as the temperature difference. For example, if the value obtained by subtracting the first temperature from the target temperature is "3.2°C", the temperature difference is "3", and if the value is "5.6°C", the temperature difference is "5". .

Instruction information generation unit 114 generates hot water supply start instruction information or hot water supply stop instruction information based on the temperature of floor FL indicated by the first temperature information and the temperature of wall WA indicated by the second temperature information. Specifically, when determination unit 112 determines that the temperature of floor FL is lower than the target temperature, instruction information generation unit 114 generates hot water supply start instruction information. Further, when the determination unit 112 determines that the temperature of the floor FL is lower than the first reference temperature and the temperature of the wall WA is lower than the second reference temperature, the instruction information generation unit 114 generates hot water supply start instruction information. do. On the other hand, when determination unit 112 determines that the temperature of floor FL is equal to or higher than the first reference temperature, or that the temperature of wall WA is equal to or higher than the second reference temperature, instruction information generation unit 114 generates hot water supply start instruction information. to avoid generating Here, the hot water supply start instruction information is first hot water supply start instruction information for instructing water heater 2 to start supplying hot water to circulation pipe 610 . Hot water supply suspension instruction information is first hot water supply suspension instruction information that instructs water heater 2 to suspend supply of hot water to circulation pipe 610 .

Instruction information generation unit 114 also generates hot water supply temperature information that indicates the temperature of hot water to be supplied from water heater 2 to circulation pipe 610 . Here, instruction information generation unit 114 determines the amount of hot water supplied from hot water heater 2 to circulation pipes 610 and 510 based on the temperature difference between the temperature of floor FL and the target temperature, which is calculated by temperature difference calculation unit 113 . Generate hot water supply temperature information that specifies the temperature. Specifically, instruction information generation unit 114 resets the temperature obtained by adding the temperature difference calculated by temperature difference calculation unit 113 to the preset hot water supply temperature as the new hot water supply temperature. Then, instruction information generation unit 114 generates hot water supply temperature information that designates the temperature of hot water supplied from water heater 2 to circulation pipes 610 and 510 to the reset hot water supply temperature.

Further, when receiving the above-described count-up information from timer 118, instruction information generation unit 114 determines that the forced stop time for forcibly stopping water heater 2 has arrived, and generates operation stop instruction information. . The instruction information generation unit 114 also generates operation stop instruction information when the operation stop instruction information is input from the operation device 8 .

Transmission unit 115 transmits hot water supply start instruction information, hot water supply suspension instruction information, hot water supply temperature information, or operation stop instruction information generated by instruction information generation unit 114 to water heater 2 .

When the target temperature information is input from the operation device 8 , the target temperature update unit 116 acquires the first reference temperature information and the target lower limit temperature information from the reference information storage unit 132 . Then, the target temperature updating unit 116 determines whether or not the target temperature indicated by the target temperature information is lower than the first reference temperature indicated by the first reference temperature information and higher than the target lower limit temperature indicated by the target lower limit temperature information. do. Then, when the target temperature is lower than the first reference temperature and higher than the target lower limit temperature, the target temperature updating unit 116 causes the target temperature candidate storage unit 122 to store the target temperature information input from the operation device 8 . Then, the target temperature updating unit 116 updates the target temperature information stored in the target temperature storage unit 131 with the target temperature information stored in the target temperature candidate storage unit 122 at preset timing.

When target temperature update unit 116 causes target temperature candidate storage unit 122 to store the target temperature information input from operation device 8 , flag management unit 117 updates the flag information stored in flag storage unit 121 . Further, when target temperature updating unit 116 updates target temperature information stored in target temperature storage unit 131 with target temperature information stored in target temperature candidate storage unit 122, flag management unit 117 stores flag storage unit 121. update flag information.

Next, the bathroom air conditioning process executed by control device 1 according to the present embodiment will be described with reference to FIGS. 6 and 7. FIG. The bathroom air conditioning process is started, for example, when the user performs an operation via the operation device 8 to start the bathroom air conditioning process. First, the temperature acquisition unit 111 acquires first temperature information indicating the temperature of the floor FL from the temperature sensor 71, and acquires second temperature information indicating the temperature of the wall WA from the temperature sensor 72 (step S101). Next, the determination unit 112 acquires the second reference temperature information stored in the reference information storage unit 132, and determines whether the temperature Tw of the wall WA is less than the second reference temperature Twb indicated by the acquired second reference temperature information. It is determined whether or not (step S102). Here, it is assumed that the determination unit 112 determines that the temperature Tw of the wall WA is equal to or higher than the second reference temperature Twb (step S102: No). In this case, instruction information generation unit 114 generates the hot water supply suspension instruction information described above, and transmission unit 115 transmits the generated hot water supply suspension instruction information to water heater 2 (step S103). At this time, water heater 2 stops supplying hot water to circulation pipe 610 when supplying hot water to circulation pipe 610, and maintains the state when supplying hot water to circulation pipe 610 is suspended. Subsequently, the process of step S122 in FIG. 7, which will be described later, is executed.

Returning to FIG. 6, on the other hand, it is assumed that the determination unit 112 determines that the temperature Tw of the wall WA is lower than the second reference temperature Twb (step S102: Yes). In this case, the determination unit 112 acquires the first reference temperature information stored in the reference information storage unit 132, and determines whether the temperature Tf of the floor FL is less than the first reference temperature Tfb indicated by the acquired first reference temperature information. It is determined whether or not (step S104). When the determination unit 112 determines that the temperature Tf of the floor FL is equal to or higher than the first reference temperature Tf (step S104: No), the process of step S103 described above is executed. In this way, determination unit 112 monitors both the temperature of floor FL and the temperature of wall WA. Stop the water supply. This prevents the user from suffering so-called low-temperature burns.

On the other hand, when the determination unit 112 determines that the temperature Tf of the floor FL is lower than the first reference temperature Tf (step S104: Yes), it acquires the target temperature information stored in the target temperature storage unit 131, and determines the temperature of the floor FL. It is determined whether or not Tf is less than the target temperature Tt indicated by the acquired target temperature information (step S105). When the determination unit 112 determines that the temperature Tf of the floor FL is equal to or higher than the target temperature Tt (step S105: No), the process of step S103 described above is performed.

On the other hand, it is assumed that the determination unit 112 determines that the temperature Tf of the floor FL is lower than the target temperature Tt (step S105: Yes). In this case, instruction information generation unit 114 generates hot water supply temperature information indicating the temperature of hot water to be supplied from water heater 2 to circulation pipe 610 , and transmission unit 115 transmits the generated hot water supply temperature information to water heater 2 . (step S106). Here, the hot water supply temperature information is information for instructing the temperature of the hot water supplied from the water heater 2 to the circulation pipe 610 to be the target temperature. After that, instruction information generation unit 114 generates the aforementioned hot water supply start instruction information, and transmission unit 115 transmits the generated hot water supply start instruction information (step S107). Next, determination unit 112 acquires standby time information from reference information storage unit 132, and the elapsed time after transmission unit 115 transmits hot water supply start instruction information to water heater 2 matches the standby time indicated by the standby time information. It is determined whether or not (step S108). Determination unit 112 repeatedly executes the process of step S108 unless the elapsed time after transmission unit 115 transmits the hot water supply start instruction information to water heater 2 does not match the waiting time described above (step S108: No).

On the other hand, when determination unit 112 determines that the elapsed time after transmission unit 115 has transmitted the hot water supply start instruction information to water heater 2 matches the standby time described above (step S108: Yes), temperature acquisition unit 111 acquires first temperature information from the temperature sensor 71 and acquires second temperature information from the temperature sensor 72 (step S109), as in step S101. Next, determination unit 112 determines whether or not temperature Tw of wall WA is lower than second reference temperature Twb (step S110), as in step S102. The second reference temperature Twb is set at 50° C., for example. Here, when the determination unit 112 determines that the temperature Tw of the wall WA is equal to or higher than the second reference temperature Twb (step S110: No), the process of step S103 described above is executed. On the other hand, it is assumed that the determination unit 112 determines that the temperature Tw of the wall WA is lower than the second reference temperature Twb (step S110: Yes). In this case, determination unit 112 determines whether or not temperature Tf of floor FL is lower than first reference temperature Tfb (step S111), as in step S104 described above. The first reference temperature Tfb is set at 48° C., for example. When the determination unit 112 determines that the temperature Tf of the floor FL is equal to or higher than the first reference temperature Tf (step S111: No), the process of step S103 described above is executed. On the other hand, when the determination unit 112 determines that the temperature Tf of the floor FL is lower than the first reference temperature Tf (step S111: Yes), the temperature Tf of the floor FL is lower than the target temperature Tt, similarly to step S105 described above. (step S112). When the determination unit 112 determines that the temperature Tf of the floor FL is equal to or higher than the target temperature Tt (step S112: No), the process of step S103 described above is performed.

On the other hand, it is assumed that the determination unit 112 determines that the temperature Tf of the floor FL is lower than the target temperature Tt (step S112: Yes). In this case, the temperature difference calculation unit 113 acquires the target temperature information stored in the target temperature storage unit 131 as shown in FIG. A temperature difference between the temperature and the target temperature indicated by the acquired target temperature information is calculated (step S113). Next, the instruction information generator 114 determines whether the temperature difference ΔT calculated by the temperature difference calculator 113 is higher than 0° C. (step S114). When the determination unit 112 determines that the temperature difference ΔT calculated by the temperature difference calculation unit 113 is 0° C. or less (step S114: No), the process of step S117, which will be described later, is executed. On the other hand, it is assumed that the determination unit 112 determines that the temperature difference ΔT calculated by the temperature difference calculation unit 113 is higher than 0° C. (step S114: Yes). In this case, the instruction information generation unit 114 resets the temperature obtained by adding the temperature difference ΔT calculated by the temperature difference calculation unit 113 to the preset hot water supply temperature as a new hot water supply temperature (step S115). Then, instruction information generation unit 114 generates hot water supply temperature information that designates the temperature of hot water supplied from water heater 2 to circulation pipes 610 and 510 as a new hot water supply temperature. Then, transmission unit 115 transmits the generated hot water supply temperature information to water heater 2 (step S116).

Subsequently, the instruction information generation unit 114 determines whether or not the hot water supply of the water heater 2 is suspended (step S117). Here, if the hot water supply stop instruction information has already been transmitted to the water heater 2 and the hot water supply start instruction information has not been transmitted to the water heater 2 thereafter, the instruction information generation unit 114 determines that the water heater 2 is inactive. I judge. When the instruction information generation unit 114 determines that the hot water heater 2 is not in a rest state (step S117: No), the process of step S119, which will be described later, is executed as it is. On the other hand, when the instruction information generating unit 114 determines that the hot water supply machine 2 is inactive (step S117: Yes), it generates hot water supply start instruction information. Then, transmission unit 115 transmits the generated hot water supply start instruction information to water heater 2 (step S118).

After that, the target temperature update unit 116 determines whether or not the content of the flag information stored in the flag storage unit 121 is "F1" (step S119). When the target temperature updating unit 116 determines that the content of the flag information is "F0" (step S119: No), the process of step S122, which will be described later, is executed.

Next, the flag management unit 117 updates the content of the flag information stored in the flag storage unit 121 to "F0" (step S121).

Subsequently, the instruction information generation unit 114 determines whether operation stop instruction information has been input from the operation device 8 (step S122). When the instruction information generation unit 114 determines that the operation stop instruction information has been input (step S122: Yes), the instruction information generation unit 114 executes the process of step S124, which will be described later. On the other hand, when the instruction information generation unit 114 determines that there is no operation stop command information input (step S122: No), it determines whether or not the forced stop time for forcibly stopping the operation of the water heater 2 has arrived. (Step S123). Here, the instruction information generation unit 114 determines that the forced stop time has come when the above-mentioned count-up information is notified from the clock unit 118 . When the instruction information generation unit 114 determines that the forced stop timing for forcibly stopping the water heater 2 has not yet arrived (step S123: No), the process of step S108 is executed again. On the other hand, when the instruction information generation unit 114 determines that the forced stop time has arrived (step S123: Yes), it generates operation stop instruction information. Then, the transmission unit 115 transmits the generated operation stop information to the water heater 2 (step S124), and the bathroom air conditioning process ends.

Next, the target temperature setting process executed by control device 1 according to the present embodiment in parallel with the above-described bathroom air conditioning process will be described with reference to FIG. This target temperature setting process is started, for example, at the same time as the above-described bathroom air conditioning process is started. First, the target temperature update unit 116 determines whether target temperature information has been input from the operation device 8 (step S201). The target temperature update unit 116 repeatedly executes the process of step S201 unless the target temperature information is input from the operation device 8 (step S201: No). On the other hand, assume that the target temperature updating unit 116 determines that the target temperature information has been input from the operation device 8 (step S201: Yes). In this case, the target temperature update unit 116 acquires the first reference temperature information from the reference information storage unit 132, and the target temperature Tt indicated by the target temperature information is less than the first reference temperature Tfb indicated by the obtained first reference temperature information. (step S202). The first reference temperature Tfb is set at 48° C., for example.

When the target temperature updating unit 116 determines that the target temperature is equal to or higher than the first reference temperature Tfb (step S202: No), the process of step S201 is executed again. On the other hand, it is assumed that the target temperature updating unit 116 determines that the target temperature is lower than the first reference temperature Tfb (step S202: Yes). In this case, the target temperature updating unit 116 acquires the target lower limit temperature information from the reference information storage unit 132, and determines whether the target temperature Tt indicated by the target temperature information is higher than the target lower limit temperature Ttl indicated by the acquired target lower limit temperature information. It is determined whether or not (step S203). Target lower limit temperature Ttl is set to 20° C., for example. When the target temperature update unit 116 determines that the target temperature is equal to or lower than the target lower limit temperature Ttl (step S203: No), the process of step S201 is executed again. On the other hand, when the target temperature update unit 116 determines that the target temperature is higher than the target lower limit temperature Ttl (step S203: Yes), the target temperature update unit 116 updates the target temperature information stored in the target temperature candidate storage unit 122 of the main storage unit 102. (Step S204). Next, the flag management unit 117 updates the content of the flag information stored in the flag storage unit 121 to "F1" (step S205). After that, the process of step S201 is executed again.

On the other hand, it is assumed that the determination unit 2112 determines that the temperature Tw of the wall WA (temperature Tf of the floor FL) is lower than the second target temperature Twt (first target temperature Tft) (step S2111: Yes). In this case, the temperature difference calculation unit 2113 calculates the temperature Tw of the wall WA (temperature Tf of the floor FL) indicated by the second temperature information (first temperature information) acquired by the temperature acquisition unit 2111 and the second target temperature Twt (the second target temperature Twt). 1 target temperature Tft) is calculated (step S2112). Next, the instruction information generation unit 2114 determines whether the temperature difference ΔT calculated by the temperature difference calculation unit 2113 is higher than 0° C. (step S2113). When the determination unit 2112 determines that the temperature difference ΔT calculated by the temperature difference calculation unit 2113 is 0° C. or less (step S2113: No), the process of step S2116, which will be described later, is executed. On the other hand, it is assumed that the determination unit 2112 determines that the temperature difference ΔT calculated by the temperature difference calculation unit 113 is higher than 0° C. (step S2113: Yes). In this case, the instruction information generation unit 2114 resets the temperature obtained by adding the temperature difference ΔT calculated by the temperature difference calculation unit 2113 to the preset hot water supply temperature as the new hot water supply temperature (step S2114). Then, instruction information generating section 2114 generates first hot water supply temperature information (second hot water supply temperature information) that designates the temperature of hot water to be supplied to circulation pipe 610 (510) as a new hot water supply temperature. transmits the generated first hot water supply temperature information (second hot water supply temperature information) (step S2115).

Subsequently, instruction information generation unit 2114 determines whether water heater 2002 is in a hot water supply stop (step S2116). When the instruction information generation unit 2114 determines that the hot water heater 2 is not in a rest state (step S2116: No), the process of step S2118, which will be described later, is executed as it is. On the other hand, when instruction information generation unit 2114 determines that water heater 2002 is inactive (step S2116: Yes), instruction information generation unit 2114 generates first hot water supply start instruction information (second hot water supply start instruction information). Then, transmission unit 2115 transmits the generated first hot water supply start instruction information (second hot water supply start instruction information) to water heater 2002 (step S2117).

After that, the target temperature update unit 2116 determines whether the content of the second flag information Fw (first flag information Ff) stored in the flag storage unit 2121 is "F1" (step S2118). When the target temperature updating unit 2116 determines that the content of the second flag information Fw (first flag information Ff) is "F0" (step S2118: No), the process of step S2121, which will be described later, is executed. On the other hand, when the target temperature update unit 2116 determines that the content of the second flag information Fw (first flag information Ff) is “F1” (step S2118: Yes), the second target stored in the target temperature storage unit 2131 The temperature information (first target temperature information) is updated with the second target temperature information (first target temperature information) stored in the target temperature candidate storage unit 2122 (step S2119). Next, the flag management unit 2117 updates the content of the second flag information Fw (first flag information Ff) stored in the flag storage unit 2121 to "F0" (step S2120). Subsequently, the processes after step S2121 are executed. The processing after step S2121 is the same as the processing after step S122 described in the first embodiment.

As described above, circulation pipe 610 according to the present embodiment is arranged such that hot water supplied from water heater 2002 flows through circulation pipe 610 and then returns to water heater 2002. After the hot water supplied from the water heater 2002 flows through the circulation pipe 510 , it is piped so as to return to the water heater 2002 . As a result, the controller 2001 can individually control the supply of hot water from the water heater 2002 to the circulation pipes 610 and 510, so that the temperature of the floor FL and the temperature of the walls WA can be controlled independently. can be set to Therefore, for example, hot water is supplied only to the circulation pipe 510 embedded in the floor FL, or tap water is supplied to the circulation pipe 610 embedded in the wall WA, thereby suppressing the temperature rise in the bathroom R. The so-called hot flashes of the user can be suppressed. In this way, an improvement in user's comfort and an effect on the user's health are expected.

Further, determination unit 2112 according to the present embodiment determines whether the temperature of floor FL is lower than the first target temperature, and instruction information generation unit 2114 causes determination unit 2112 to determine whether the temperature of floor FL is the first target temperature. When it is determined that the temperature is lower than the target temperature, second hot water supply start instruction information is generated. Further, determination unit 2112 determines whether the temperature of wall WA is less than the second target temperature, and instruction information generation unit 2114 determines that determination unit 2112 determines that the temperature of wall WA is less than the second target temperature. When determined, first hot water supply start instruction information is generated. In addition, the determination unit 2112 determines whether the temperature of the floor FL is lower than the preset first reference temperature, and the instruction information generation unit 2114 causes the determination unit 2112 to determine whether the temperature of the floor FL is the first reference temperature. If determined to be less than the second hot water supply start instruction information is generated. On the other hand, when determination unit 2112 determines that the temperature of floor FL is equal to or higher than the first reference temperature, instruction information generation unit 2114 avoids generating second hot water supply start instruction information. Furthermore, determination unit 2112 determines whether the temperature of wall WA is less than the second reference temperature, and instruction information generation unit 2114 determines whether determination unit 2112 determines that the temperature of wall WA is less than the second reference temperature. When determined, first hot water supply start instruction information is generated. On the other hand, when determining unit 2112 determines that the temperature of wall WA is equal to or higher than the second reference temperature, instruction information generating unit 2114 avoids generating first hot water supply start instruction information. This prevents the temperature of the floor FL and the wall WA from rising excessively.

Furthermore, the temperature difference calculation unit 2113 according to the present embodiment calculates the temperature difference between the temperature of the floor FL and the first target temperature, and the instruction information generation unit 2114 calculates the hot water heater temperature based on the calculated temperature difference. First hot water supply temperature information specifying the temperature of hot water supplied from 2002 to circulation pipe 510 is generated. Further, temperature difference calculation unit 2113 calculates the temperature difference between the temperature of wall WA and the second target temperature, and instruction information generation unit 2114 generates a temperature difference from water heater 2002 to circulation pipe 610 based on the calculated temperature difference. Second hot water supply temperature information specifying the temperature of hot water to be supplied is generated. As a result, water heater 2002 supplies hot water to circulation pipe 510 at a temperature suitable for efficiently bringing the temperature of floor FL closer to the first target temperature, and water heater 2002 to circulation pipe 610 reduces the temperature of wall WA to the second target temperature. Since hot water with a temperature suitable for efficiently approaching the target temperature is supplied, the temperature of the floor FL is easily maintained at the first target temperature and the temperature of the wall WA is easily maintained at the second target temperature.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, as shown in FIG. 14, a connecting pipe 3941 communicating with the circulation pipe 610 and a connecting pipe 3942 communicating with the circulation pipe 510 may be connected to each other via a three-way valve 3991 . In addition, in FIG. 14, the same reference numerals as in FIG. 2 denote the same configurations as those in the first embodiment. Water heater 3002 is also connected to three-way valve 3991 via circulation pipe 3951 . Here, three-way valve 3991 causes hot water flowing in from circulation pipe 610 to flow out to circulation pipe 510 or water heater 3002 in accordance with a control signal input from control device 3001 .

Water heater 3002 has the same configuration as water heater 2 according to Embodiment 1, and supplies the generated hot water to circulation pipe 610 through hot water supply pipe 931 . Operation device 3008 is the same as operation device 8 according to Embodiment 1, and operates a push switch to generate circulation mode change instruction information for instructing a change in the circulation mode of hot water supplied to circulation pipe 610. Output to the control device 3001 is possible.

The control device 3001 controls the state of the three-way valve 3991 by outputting a control signal to the three-way valve 3991 based on circulation mode change instruction information input from the operation device 3008 . For example, assume that control device 3001 is executing the bathroom air conditioning process described in the first embodiment in a state where three-way valve 3991 causes hot water flowing in from circulation pipe 610 to flow out to circulation pipe 510 . At this time, when the control device 3001 receives the circulation mode change instruction information from the operation device 3008 , the control device 3001 forcibly terminates the bathroom air conditioning process and outputs a control signal to the three-way valve 3991 . By doing so, the three-way valve 3991 is changed to a state in which the hot water flowing in from the circulation pipe 610 flows out to the water heater 3002 . Then, control device 3001 transmits to water heater 3002 hot water temperature information instructing to lower the temperature of hot water supplied from water heater 3002 to circulation pipe 610, thereby reducing the temperature of wall WA to the temperature indicated by the hot water temperature information. can be cooled to

According to this configuration, when the temperature in the bathroom R rises, for example, the circulation mode of the hot water supplied to the circulation pipe 610 can be changed, so that the hot flashes of the user can be suppressed.

In each embodiment, an example in which the circulation pipe 610 is arranged on the wall WA has been described, but the circulation pipe 610 is not limited to this, and may be embedded in the ceiling of the bathroom R, or may be connected to the ceiling. It may be embedded over both walls WA.

Various functions of the control devices 1, 2001, and 3001 according to the present invention may be implemented by software, firmware, or a combination of software and firmware. In this case, the software or firmware is written as a program, and the program is stored on computer-readable media such as flexible discs, CD-ROMs (Compact Disc Read Only Memory), DVDs (Digital Versatile Discs) and MOs (Magneto-Optical Discs). By storing and distributing the program in a recording medium, and reading and installing the program in the computer, a computer capable of realizing each function described above may be configured. When each function is shared between an OS (Operating System) and an application, or when the OS and an application cooperate with each other, only portions other than the OS may be stored in the recording medium.

Furthermore, it is also possible to superimpose each program on a carrier wave and distribute it via a network. For example, the program may be posted on a bulletin board (BBS, Bulletin Board System) on the network and distributed via the network. Then, these programs may be activated and executed in the same manner as other application programs under the control of the OS so that the above-described processing can be executed.
