  (1) Water filling operation

  The processing procedure of the water filling operation of the hot water storage tank 4 will be described with reference to FIGS. 5, 6, 7, 8, 9 and 10. 5 to 9 show an example of the processing procedure of the water filling operation, and FIG. 10 shows the water filling operation. In FIGS. 5 to 9, a, b, c, d, e, f, and g indicate a connecting portion between the flowcharts.

  This processing procedure is an example of the water filling control method of the present invention, and is a tank water filling operation start process F1, a quick water replenishment end determination process F2, a quick water replenishment end process F3, a refill water switching valve forgetting check process F4, a tank water filling operation. It includes an end determination process F5, a normal water replenishment process F6, a tank water filling abnormal end process F7, and a tank water filling normal end process F8.

  After the power is turned on, it is monitored whether or not the tank water filling switch 87 is turned on (step S101). If the tank water filling switch 87 is turned on (YES in step S101), the tank water filling operation start process F1 is executed. In addition, when performing tank water filling, it is necessary to switch the supplementary water switching valve 81 (manual) to the supplemental water circuit 79 side in advance.

  In the tank water filling operation start process F1, when the tank water filling operation is started, the rapid water filling switch 91 is turned on and the tank water filling display unit 89 blinks (step S102), and the start of the rapid water filling operation is displayed. In this case, after opening the tank opening / closing valve 43 (step S103), the hot water storage tank switching valve 40 is opened to the tank side (step S104), and the detection electrode 9B (HL) is turned off as the determination process of the water level detected by the water level sensor 9. Is determined (step S105). If the detected water level of the water level sensor 9 detects the high level HL, that is, if the detection electrode 9B (HL) is not OFF (NO in step S105), high-speed water filling is unnecessary, and the tank water filling display portion 89 is turned on. (Step S106), water supply from the supply line 13 side may be performed.

  If the water level sensor 9 has not detected the high level HL, that is, if the detection electrode 9B (HL) is OFF (YES in step S105), high-speed water filling is necessary, so the on-off valve 83 is closed (step S107). Then, the pouring amount counter 92 is cleared (step S108), and the pouring solenoid valve 78 is opened (step S109). In this case, in order to detect an abnormality of the supplementary water switching valve 81 or whether the supplementary water switching valve 81 has been switched to the supplemental water circuit 79 side with the bath water flow switch 85, a single transfer is used, for example, a restriction flow rate of 14 [liter]. Do hot water. Further, the solenoid valve 78 is opened after the on-off valve 83 is closed.

  In the quick water replenishment determination process F2, ON / OFF of the water flow switch 85 is monitored (step S110). If there is no water flow, the water flow switch 85 is turned OFF (YES in step S110), and the water level sensor 9 is at the detected water level. As a determination process, it is determined whether the detection electrode 9B (HL) is ON (step S111). In this case, if the water level sensor 9 detects the high level HL from the start of water filling, it is assumed that a predetermined time, for example, 5 [minutes] has elapsed since the pouring electromagnetic valve 78 is closed (OFF). If the water level sensor 9 detects the high level HL in the confirmation of the detection level of the water level sensor 9 (YES in step S111), the water level of the hot water storage tank 4 is the appropriate water level, so the rapid water replenishment end process Move to F3. That is, in this case, the hot water solenoid valve 78 is closed (step S112), the tank water filling display portion 89 is turned on (step S113), and the end of the rapid water refilling is displayed.

  If the bath water flow switch 85 is not OFF (NO in step S110), it is determined that the refill water switching valve 81 is abnormal (step S114), the pouring electromagnetic valve 78 is closed (step S115), and the tank water filling display portion 89 is displayed. Is turned on (step S116).

  If the detection level of the water level sensor 9 is confirmed (step S111) and the water level sensor 9 is not at the high level HL (NO in step S111), whether or not a predetermined amount of pouring, for example, 210 [liter] is poured. Confirmation (step S117), and if 210 [liter] is not poured (NO in step S117), the process returns to step S110. This pouring amount is confirmed by the detection value of the pouring amount sensor 93.

  If 210 [liter] has been poured (YES in step S117), the water level corresponding to that has not been obtained, so that tank filling is abnormal (step S118), and the molten solenoid valve 78 is closed (step S119). The tank water filling display unit 89 is turned on to notify the end of water replenishment (step S120).

  In this state, the operation of the tank water filling switch 87 is monitored (step S121), and if there is no operation of the tank water filling switch 87 (YES in step S121), the process proceeds to the forgetting to replace supplementary water switching valve check process F4. In this check process F4, it is determined whether or not the check of the refill water switching valve 81 is completed (step S122). If the check of the refill water switch valve 81 is not completed (YES in step S122), a predetermined time, for example, 9 It is checked whether [minutes] 30 [seconds] have elapsed (step S123). If 9 [minutes] and 30 [seconds] have elapsed since the end of the rapid water replenishment (YES in step S123), the hot water solenoid valve 78 is opened (step S124), and it is confirmed whether the water flow switch 85 is ON ( If the bath flow switch 85 is ON (YES in step S125), it is confirmed whether, for example, 5 [seconds] have elapsed as a continuous constant time (step S126).

  After continuous elapse of 5 seconds (YES in step S126), the pouring electromagnetic valve 78 is closed (step S127), and the check of the refill water switching valve 81 is ended (step S128).

  If the bath flow switch 85 is not ON (NO in step S125), and if 5 seconds have not elapsed (NO in step S126), for example, 20 [ Second] has elapsed (step S129). If 20 seconds have elapsed since the start of the check (YES in step S129), the pouring solenoid valve 78 is closed (step S130), and the tank water filling abnormality ( Step S131).

  Further, in the tank water filling operation end determination process F5, it is determined whether, for example, 10 [min] has elapsed before the end of the rapid water replenishment (step S132). If it does not reach the high level HL, the process proceeds to the tank water filling abnormal end process F7.

  If 10 minutes have not elapsed since the end of the rapid water replenishment (YES in step S132), the process proceeds to the normal water replenishment process F6. In this normal water replenishment process, it is determined whether the high level HL is detected as the detection process of the water level detected by the water level sensor 9, that is, whether the detection electrode 9B (HL) is ON (step S133). If the detection electrode 9B is ON (YES in step S133), the makeup water electromagnetic valve 17 is closed (step S134). From this state, the pump ON timing is confirmed (step S135). If the pump ON timing comes (YES in step S135), the circulation pump 26 is operated (step S136), and the process returns to step S121 (FIG. 7).

  In step S133, if the water level sensor 9 does not detect the high level HL, that is, if the detection electrode 9B (HL) is not ON (NO in step S133), the makeup water electromagnetic valve 17 is opened (step S137), and the water level It is determined whether the high level HL is detected as the detection level determination process of the sensor 9, that is, whether the detection electrode 9A (LL) is OFF (step S138). If the low level LL is not detected, the detection electrode 9A is detected. If (LL) is OFF (YES in step S138), the circulation pump 26 is turned OFF (step S139), and the process returns to step S121 (FIG. 7). If the low level LL is detected, that is, if the detection electrode 9A (LL) is not OFF (NO in step S138), the process returns to step S121 (FIG. 7).

  In the tank water filling operation end determination process F5, when 10 minutes have elapsed from the end of the rapid water replenishment (NO in step S132), it is confirmed whether the water level sensor 9 is not at the high level HL, that is, whether the detection electrode 9B (HL) is OFF. (Step S140). If the water level sensor 9 has not detected the high level HL (YES in step S140), the process proceeds to the tank water filling abnormality termination process F7. If the water level sensor 9 detects the high level HL, that is, if the detection electrode 9B (HL) is not OFF (NO in step S140), the water filling completion is stored (step S141), and the tank water filling is normally completed. The process proceeds to process F8. In this case, the determination of the high level HL of the water level sensor 9 is based on whether or not the detection electrode 9B is continuously turned on for, for example, 10 [seconds] as a constant time.

  In the tank water filling abnormality termination process F7, the makeup water electromagnetic valve 17 is opened (step S142), and after the operation of the circulation pump 26 (step S143), for example, 5 [minutes] elapsed is monitored (step S144). Steps S140, S142, S143, and S144 are executed until 5 minutes have elapsed. If 5 minutes have elapsed as the accumulated time (YES in step S144), a water filling abnormality (step S145) is established. The valve 17 is closed (step S146), the circulation pump 26 is turned off (step S147), the on-off valve 83 is opened (step S148), and the tank water filling is abnormally terminated.

  In the tank water filling normal end processing F8, the makeup water electromagnetic valve 17 is closed (step S149), the circulation pump 26 is turned off (step S150), the tank water filling display portion 89 is turned off (step S151), and the on-off valve 83 is opened ( Step S152), tank filling is completed.

  By the procedure described above, the water filling operation is executed as shown in FIG.

  Referring to FIG. 11 for the pump ON timing described above, FIG. 11 shows a table of pump ON timing and pump operation.

  According to the pump ON timing table 124, the circulating pump 26 performs an intermittent pump operation with a pump operation of 2 [minutes] and a stepwise increase in the conduction stop time. Thereby, air purge of a circulation circuit etc. is performed.

  (2) Low temperature heating operation

  In this low temperature heating operation, the hot water HM1 in the hot water storage tank 4 is mixed with the hot water HM1 circulated through the low temperature heater 52 to lower the temperature, and the hot water HM1 having the required temperature is circulated through the low temperature heater 52.

  (3) High temperature heating operation

  When an operation signal is input from the high-temperature heater 54 to the control device 82, the operation of the circulation pump 26 is started. The detected temperature T3 of the temperature sensor 42 and the detected temperature T4 of the temperature sensor 44 are compared. If T4> T3, the hot water tank switching valve 40 is opened on the hot water tank 4 side. Hot water HM1 in the hot water storage tank 4 is sent from the circulation pump 26 to the secondary heat exchanger 30 and the primary heat exchanger 28. Combustion of the burner 46 is controlled so that the detected temperature T5 of the temperature sensor 48 on the outlet side of the primary heat exchanger 28 is, for example, 80 [° C.] as a constant temperature suitable for radiant heating. If the hot water HM1 in the hot water storage tank 4 is a constant temperature suitable for heat radiation heating, for example, 80 [° C.], the heating by the primary heat exchanger 28 is not performed.

  The heated hot water HM1 flows into the high-temperature heater 54 and dissipates heat. In this case, the hot water HM1 flowing into the circulation path 8 and the high temperature distribution valve 62 is diverted to the circulation path 8A, passes through the hot water supply heat exchanger 56, joins with the return hot water HM1 from the high temperature heater 54, and enters the hot water storage tank 4. It reaches. In this case, the circuit of the hot water supply heat exchanger 56 formed by the circulation path 8A is used as a circulation circuit until the high-temperature heater 54 can be operated and a hot water supply heating path that can immediately respond to a hot water supply request.

  The hot water HM1 deprived of heat through the high-temperature heater 54 and the return hot water HM1 from the hot water supply heat exchanger 56 are mixed, and this mixed hot water HM1 is detected by the temperature sensor 42. The detected temperature T3 of the temperature sensor 42 is compared with the detected temperature T4 of the temperature sensor 44 on the outlet side of the hot water storage tank 4. If T4 <T3, the opening degree of the hot water tank switching valve 40 is switched from the hot water tank 4 side to the branch flow path 24 side, and the use of the hot water HM1 in the hot water tank 4 is stopped. That is, heat is stored by the hot water HM1 to save the heat.

  (4) Hot water supply operation

  The water supply W that has entered the heating / hot water supply / remembrance device 2 from the water supply port reaches the branch point of the bypass 60 through the temperature sensor 64, the water amount sensor, the water control valve, and the like. The water supply W flowing to the bypass 60 side is mixed with the hot water HW for mixing. Further, the feed water W that has flowed into the hot water supply heat exchanger 56 via the secondary heat exchanger 58 is subjected to heat exchange with the hot water HM1 in the hot water supply heat exchanger 56, and becomes hot water HW. Passes the mixing valve installed at the branch point. The opening of the mixing valve is adjusted so that the detected temperature T8 of the temperature sensor 66 becomes the set temperature, and the hot water HW heated by the hot water supply heat exchanger 56 is mixed with the feed water W to be adjusted to the set temperature. The hot water is taken out from the hot spring outlet.

  In the circulation operation of the hot water HM1, when the water amount sensor in the hot water supply circuit 36 senses flowing water, the circulation pump 26 starts operation. The detected temperature T3 of the temperature sensor 42 and the detected temperature T4 of the temperature sensor 44 are compared. When T4> T3, the hot water tank switching valve 40 is opened on the hot water tank 4 side. Hot water HM1 in the hot water storage tank 4 is sucked into the circulation pump 26 and sent to the secondary heat exchanger 30 and the primary heat exchanger 28. The temperature of the hot water HM1 that has passed through the primary heat exchanger 28 and the secondary heat exchanger 30 is detected by the temperature sensor 48, and the burner 46 is adjusted so that the detected temperature T5 is, for example, 80 [° C.]. The combustion control is performed. If the hot water HM1 in the hot water storage tank 4 is at a constant temperature, for example, 80 [° C.], the heating by the burner 46 is not performed.

  The hot water HM1 at a constant temperature, for example, 80 [° C.] performs heat exchange with the hot water supply W side in the hot water supply heat exchanger 56. For example, when the hot water supply capacity is No. 24, the amount of heat is 41.86 [kW] (36,000 [kcal / h]). If the hot water temperature of the hot water storage tank 4 is 80 [° C.] and the circulation rate of the circulation pump 26 is about 12 [liter / min], the temperature of the hot water HM1 returning to the hot water storage tank 4 is about 30 [° C.] If all of the hot water HM1 is used for hot water supply heat exchange, the temperature of the hot water in the hot water storage tank 4 is about 30 [° C.]. If the number of hot water supply numbers decreases, the temperature drop of the hot water HM1 returning to the hot water storage tank 4 is small, and the hot water temperature of the hot water storage tank 4 is always 30 [° C.] or higher.

  Further, the detected temperature T3 of the hot water HM1 deprived of heat by the hot water supply heat exchanger 56 and the detected temperature T4 of the temperature sensor 44 are compared. If T4 <T3, the hot water storage tank switching valve 40 is switched from the hot water storage tank 4 side to the branch flow path 24 side, and the hot water HM1 of the hot water storage tank 4 is not used. Thereby, the heat loss by use of the hot water HM1 of the hot water storage tank 4 is suppressed.

  (5) Bathtub pouring operation

  When the hot water solenoid valve 78 is opened at the time of hot water supply, the hot water supply circuit 36 is connected to the remedy circuit 38, and the hot water HW flowing through the hot water supply circuit 76 branched from the hot water supply circuit 36 passes through the remedy heat exchanger 70. 68 is poured. In this case, the remedy pump 72 is not used. If the water supply W is clean water, there is sufficient water pressure, and the hot water HW is poured into the bathtub 68 using the water pressure.

  (6) Bath water tracking operation

  When a chasing operation signal is input from the remote control device 94 to the control device 82, the chasing pump 72 is started to operate. Thereby, the bath water BW is circulated to the reheating circuit 38, and heat of the hot water HM1 is heat-exchanged by the reheating heat exchanger 70 to be heated. When the detected temperature T9 of the temperature sensor 74 reaches the set temperature, the chasing operation is ended and the chasing pump 72 is stopped.

  In this case, when the follow-up operation signal is input to the control device 82, the operation of the circulation pump 26 is started. The detected temperature T3 of the temperature sensor 42 and the detected temperature T4 of the temperature sensor 44 are compared. If T4> T3, the hot water tank switching valve 40 is switched to the hot water tank 4 side. Hot water HM1 in the hot water storage tank 4 is sucked into the circulation pump 26 and sent to the secondary heat exchanger 30 and the primary heat exchanger 28. The temperature of the hot water HM1 that has passed through the primary heat exchanger 28 and the secondary heat exchanger 30 is detected by the temperature sensor 48, and the burner 46 is adjusted so that the detected temperature T5 is, for example, 80 [° C.]. The combustion control is performed. If the hot water HM1 in the hot water storage tank 4 is at a constant temperature, for example, 80 [° C.], the heating by the burner 46 is not performed.

  The high temperature distribution valve 62 is also opened on the circulation path 8B side, the warm water HM1 is allowed to flow on the circulation path 8B side, and the heat of the warm water HM1 is exchanged with the bath water BW between the remedy circuit 38 and the circulation path 8B. In this case, the high temperature distribution valve 62 also flows the hot water HM1 to the hot water supply heat exchanger 56 side. The hot water HM1 deprived of the bath water BW by the heat exchanger for remedy 70 merges with the hot water HM1 that has passed through the hot water supply heat exchanger 56 in the circulation path 8A, and is returned to the hot water storage tank 4. The circulation path 8A passing through the hot water supply heat exchanger 56 from the high temperature distribution valve 62 is used as a hot water supply circuit that can immediately respond to a hot water supply request.

  The hot water HM1 deprived of heat by the heat exchanger for remedy 70 is mixed with the hot water HM1 that has passed through the hot water supply heat exchanger 56, and the detected temperature T3 and the detected temperature T4 of the mixed hot water HM1 are compared, and T4 If T3, the hot water tank switching valve 40 is switched from the hot water tank 4 side to the branch flow path 24 side, and the hot water HM1 of the hot water tank 4 is not used. That is, heat is stored by the hot water HM1 to save the heat.

  (7) Solar heat collection operation

  The temperature rise of the hot water HM2 due to solar heat is related to the amount of solar radiation, and according to the test results, it has been confirmed that an increase of about 30 [° C.] can be expected even in winter. Regardless of the season, the hot water temperature of the hot water storage tank 4 is about 30 [° C.], so the hot water storage tank 4 including the solar heat exchanger 12 that exchanges heat with the hot water HM2 that is a solar heat medium is 30 [ The temperature of the hot water storage tank 4 can be raised to about 60 [° C.] by 30 [° C.] + 30 [° C.]. In this case, if the required temperature of the low-temperature heater 52 described above is, for example, 60 [° C.], the heat of the hot water HM1 stored in the hot water storage tank 4 can be used for heat dissipation of the low-temperature heater 52. Of course, more heat can be used in summer.

  With regard to the solar heat that can be used for the heat collecting circuit 6, the sunrise and sunset times vary depending on the season, and the time zone with solar radiation also varies. The operation start time and stop time of the heat collecting pump 14 are set in the control device 82 through the remote control device 94 according to the season (summer, winter, intermediate period). The season may be determined using the detected temperature T10 of the temperature sensor 80.

  Therefore, when the set time reaches the operation start time of the heat collecting pump 14, the heat collecting pump 14 is operated. The hot water HM2 circulates in the heat collecting circuit 6, and the temperature sensor 20 detects the temperature of the hot water HM2 entering the heat collecting panel 10. Since the heat collection panel 10 is means for heating the hot water HM2 with solar heat, if there is solar radiation, the detected temperature T2 of the hot water HM2 that has passed through the heat collection panel 10 rises. Therefore, if T2> T1, it is determined that solar heat is collected, and the operation of the heat collection pump 14 is continued. On the other hand, if T2 ≦ T1, the temperature of the hot water HM2 that has passed through the heat collection panel 10 has decreased, so it is determined that there is no solar heat collection, the operation of the heat collection pump 14 is stopped, and the heat collection End the operation.

  In this case, if there is a temperature rise (T2> T1) in the heat collecting panel 10, if the detected temperature T2 is lower than the detected temperature T4 of the temperature sensor 44 (T2 <T4), the hot water HM1 in the hot water storage tank 4 Heat is lost to the hot water HM2, resulting in heat loss. In order to prevent this, the solar switching valve 16 is switched to the bypass path 18 side and circulated. This circulation continues until T2> T4. When T2> T4, the solar switching valve 16 is switched to the solar heat exchanger 12 side, and the heat of the hot water HM2 is exchanged with the hot water HM1 in the hot water storage tank 4. I do. When the set time comes to the stop time of the heat collection pump 10, the operation of the heat collection pump 10 is stopped.

  As a result, by collecting solar heat in the hot water HM2 and exchanging heat of the hot water HM2 for the hot water HM1, heat can be stored in the hot water storage tank 4 through the hot water HM1.

  The advantages and effects of the above embodiment are as follows.

  (1) In filling the hot water storage tank of such a solar heat utilization system, the hot water storage tank is incorporated in the heating circuit in order to use solar heat for heating. Since the heating circuit is cut off from the water supply, it is common to fill the water with a water replenishing solenoid valve. However, since the water discharge is small, it takes about 90 minutes to fill the hot water storage tank. Moreover, the next operation cannot be confirmed while the water is filled, so you just have to wait. For this reason, the time required for water filling affects construction costs and sales promotion, but such a problem is solved in the above embodiment.

  (2) Increasing the water discharge is effective for shortening the water filling time. There is a method to increase the water discharge amount of the water replenishing solenoid valve, but it is not easy to secure the water discharge space. In the said embodiment, the pouring circuit is utilized, the circuit and control which perform water filling are utilized, and the speed-up is aimed at. Since automatic pouring is a hot water filling circuit to the bathtub, the amount of pouring is sufficient, and an edge cutting device is also incorporated. The hot water storage time can be shortened by providing a flow path from the circuit to the hot water storage tank side. However, water filling the hot water storage tank is a circuit that is used only at the time of equipment purchase, and is rarely used when draining the water in the hot water storage tank for maintenance. It is not necessary in view of control load and cost, and a manual valve is sufficient. However, since it is a manual valve, it is possible to forget to switch the valve. Therefore, reliable control of water filling is realized by performing control for notifying valve switching forgetting by using control for checking valve switching during water filling.

  (3) The control load can be reduced, the water filling time to the hot water storage tank can be shortened, an erroneous operation can be notified, and the convenience during construction can be improved.
