  However, in the preliminary drying in which the object to be dried is dried only with unheated air, the moisture that can be removed from the object to be dried is relatively small. Therefore, a long period of time is required to remove a certain amount of moisture from the object to be dried. Is required. Therefore, a long period is required to complete the drying of the object to be dried by using the preliminary drying and the main drying together.

  This invention is made | formed in view of said subject, The objective is to provide the bathroom drying system which can aim at shortening of the period which a drying operation requires, maintaining energy saving property.

The air heating means is configured to be able to heat the air with hot water generated by the hot water generation unit, hot water stored in the hot water storage tank, or heated hot water heated by the heating unit,
In a state in which the air blowing unit is operated after the command receiving unit receives the start of the drying operation, and the air heating unit does not heat the air by the heated hot water heated by the heating unit. Preliminary drying for blowing air into the bathroom is performed until a processing switching time that is a set period prior to the desired drying completion time received by the command receiving unit, and the air blowing means is operated, and The bathroom is configured to perform the main drying in which air is blown into the bathroom in a state where the air heating means heats the air with the heated hot water heated by the heating unit from the process switching time to the desired end time. It is a drying system, and its characteristic configuration is

That is, as shown in FIG. 5, when the heat medium in the first circulation path 31 is circulated by the first circulation pump P1, the amount of warm water circulated in the second circulation path 32 is reduced by the second circulation pump P2, that is, If the flow rate of the hot water passing through the first heat exchanger 21 per unit time is reduced, the temperature of the hot water after passing through the first heat exchanger 21 is relatively high, so that the temperature of the hot water in the hot water storage tank 23 is To rise. On the other hand, if the circulation amount of the warm water in the second circulation path 32 is increased by the second circulation pump P2, that is, if the flow rate of the warm water passing through the first heat exchanger 21 per unit time is increased, the first heat Since the temperature of the hot water after passing through the exchanger 21 is relatively low, the temperature of the hot water flowing into the hot water tank 23 is lowered. For example, the operation control unit C controls the operation of the second circulation pump P2 in the hot water storage tank 23 so that the temperature of the flowing hot water becomes 60 ° C.

  Hereinafter, the cool air operation, the ventilation operation, the heating operation, the heat drying operation, and the eco drying operation as the drying operation in the present embodiment of the bathroom heater / dryer A will be described.

(Cool wind driving)
The cool air operation is an operation in which the air sucked from the bathroom M is blown into the bathroom M through the circulation ventilation path 18 without heating. Specifically, when the cool air operation switch 47 is pressed by the user, the operation control unit C operates the circulation fan 6 in a state where the flow of the heat medium in the heating circulation path 8 is stopped and exhausts the heat. In this operation, the fan 7 is operated and a part of the air sucked from the inside of the bathroom M is discharged to the outside through the exhaust duct 5, and the remaining air is blown into the bathroom M through the circulation ventilation path 18 without heating. Moreover, the operation control part C adjusts the direction of the movable louver 19 so that the blowing direction of the air into the bathroom M becomes the set blowing direction for the cool wind operation.

[Ventilation operation]
The ventilation operation is an operation in which the air sucked from the bathroom M is exhausted from the exhaust duct 5. Specifically, when the ventilation operation switch 46 is pressed by the user, the operation control unit C stops the operation of the circulation fan 6 and stops the flow of the heat medium in the heating circulation path 8. Then, the exhaust fan 7 is operated. In addition, the operation control unit C adjusts the operating state so that the movable louver 19 is closed.

[Heating operation]
The heating operation is an operation in which air in the bathroom M is taken in and heated, and then the heated air is blown out into the bathroom M. Specifically, when the heating operation switch 45 is pressed by the user, the operation control unit C stops the exhaust fan 7 and activates the circulation fan 6, and the heating unit 24 heats the first heat exchanger 21. Control is performed so that the heated air is blown into the bathroom M in a state where the heating heat exchanger 9 heats the air with the heated hot water generated by heating the heated water. That is, as shown in FIG. 6, the hot water circulates in the first circulation path 31 and the second circulation path 32 indicated by bold lines, and the heating medium circulates in the heating circulation path 8. The hot water supply apparatus B is controlled.
And the flow volume of the heat medium which flows through the heating circuit 8 is controlled so that the warm air temperature in the blower outlet 4 is maintained in a preset temperature range. During the heating operation, the heating unit 24 is controlled to always burn.

  Thereby, the air heated by the heat exchanger 9 for heating is blown out into the bathroom M from the blower outlet 4. Further, the operation control unit C adjusts the operation state of the circulation fan 6 so that the flow rate of the air blown into the bathroom M becomes the ventilation amount for heating, and swings the movable louver 19. .

[Heating and drying operation]
In the heat drying operation, for example, a part of the air sucked from the inside of the bathroom M as a drying space where a drying object such as clothes containing moisture is placed is taken out through the exhaust duct 5 after taking a bath. However, in the state where the heating medium heated using the heated hot water generated by the heating unit 24 is passed through the heating circulation path 8, the remaining air is heated by the heating heat exchanger 9 and then blown. In this operation, the air is blown into the bathroom M from the outlet 4.

Specifically, when the heating / drying operation switch 44 is pressed by the user, the operation control unit C operates the exhaust fan 7 and the circulation fan 6 and is heated in the first heat exchanger 21 by the heating unit 24. Control is performed so that heated air is blown into the bathroom M in a state where the heat exchanger 9 for heating heats the air with the heated warm water generated by heating the warm water. Moreover, the circulation state of the warm water and the heat medium in the warm water supply device B is the circulation state shown in FIG. 6 as in the above heating operation.
And the flow volume of the heat medium which flows through the heating circuit 8 is controlled so that the warm air temperature in the blower outlet 4 is maintained in a preset temperature range. During the heating and drying operation, the heating unit 24 is controlled to always burn.

[Eco-drying operation]
In the eco-drying operation, for example, a part of the air sucked from the bathroom M as a drying space where a dry object such as clothes containing moisture is arranged is discharged to the outside through the exhaust duct 5 while being heated. After the preliminary drying in which air is blown into the bathroom M in a state where the heating heat exchanger 9 does not heat the air with the heated hot water heated by the heating heat exchanger 9, the heating heat exchanger 9 heats the air with the heated hot water heated by the heating unit 24. In this state, the main drying is performed by blowing air into the bathroom M. In the preliminary drying, when the heat storage amount of the hot water tank 23 satisfies the heat sufficient condition, the air heated by the heating heat exchanger 9 with the hot water stored in the hot water tank 23 is blown out from the outlet 4 into the bathroom M. It is configured.

  Specifically, after the eco-drying operation switch 41 of the remote controller R is pressed by the user, that is, after the remote controller R accepts the start of the eco-drying operation, the operation control unit C, the exhaust fan 7 and the circulation fan 6. The heating heat exchanger 9 blows out air into the bathroom M without heating the air by the heated hot water generated by heating the hot water heated in the first heat exchanger 21 by the heating unit 24. Preliminary drying is performed up to the processing switching time that is a set period before the desired drying operation end time accepted by the remote controller R, and the exhaust fan 7 and the circulation fan 6 are operated and heated by the heating unit 24. The main drying in which air is blown into the bathroom M in a state where the heating heat exchanger 9 heats the air with heated hot water is performed from the process switching time to the desired end time.

  The desired end time of the drying operation accepted by the remote controller R is a time at which the user wants to finish drying the object to be dried, and is input by the user from the desired end time input unit 42 of the remote controller R before the eco-drying operation is performed. It is what is done.

The set period, which is a period from the process switching time to the desired end time, is obtained by, for example, the operation control unit C from the current time to the desired end time input by the user, and according to the length of the time. Is set. That is, when the time from the current time to the desired end time input by the user is long, the predrying time can be extended, and thus the object to be dried is dried to some extent in the predrying. Therefore, even if the subsequent main drying is shortened, the object to be dried can be dried at the desired end time, so that the setting period can be set short.
In the present embodiment, in the preliminary drying, a heated air blowing process and a non-heated air blowing process described later are performed, and a hot air drying process described later is performed as the main drying.

  Then, in the preliminary drying, when the amount of heat stored in the hot water storage tank 23 satisfies the heat sufficient condition, the operation control unit C uses the hot water stored in the hot water storage tank 23 to heat the air heated by the heating heat exchanger 9 in the bathroom M. When the heated air blowing process is performed and the amount of heat stored in the hot water storage tank 23 does not satisfy the heat sufficient condition, the heating heat exchanger 9 blows out the unheated air into the bathroom M. Perform the process.

  In the present embodiment, the heat storage amount of the hot water storage tank 23 determined by the temperature detected by the temperature detection units T1 to T5 functioning as the heat storage amount detection unit in the preliminary drying is equal to or greater than the set heat storage amount. In this case, it is determined that the sufficient heat condition has been satisfied, and a heating and blowing process is performed in which the air heated by the heating heat exchanger 9 using the hot water stored in the hot water storage tank 23 is blown into the bathroom M. On the other hand, the operation control unit C determines that the sufficient heat condition is not satisfied when the heat storage amount of the hot water storage tank 23 obtained from the temperatures detected by the temperature detection units T1 to T5 is less than the set heat storage amount. The non-heating air blowing process which blows off the air which the heat exchanger 9 for heating does not heat in the bathroom M is implemented.

  About the heat storage amount of the hot water storage tank 23, it is calculated | required by the operation control part C from the volume and temperature of the hot water accommodated in the hot water storage tank 23. FIG. For example, in the hot water storage tank 23, the hot water stored above the temperature detection unit T1 is stored between the temperature detection unit T2 and the temperature detection unit T1, the amount of stored heat required to be the detected temperature of the temperature detection unit T1. The amount of heat storage required for the hot water to be the detected temperature of the temperature detection unit T2, the amount of heat storage required for the hot water contained between the temperature detection unit T3 and the temperature detection unit T2 to be the detection temperature of the temperature detection unit T3, The amount of stored heat required for the hot water stored between the temperature detection unit T4 and the temperature detection unit T3 to be the detected temperature of the temperature detection unit T4, and is stored between the temperature detection unit T5 and the temperature detection unit T4. The sum of the heat storage amounts that are determined as the hot water being the detected temperature of the temperature detection unit T <b> 5 is determined as the heat storage amount of the hot water storage tank 23.

  The set heat storage amount is set to, for example, a predicted demand heat amount that is a heat demand amount predicted from a past heat use history by the user. Therefore, in this embodiment, in pre-drying, when the heat storage amount of the hot water storage tank 23 calculated | required based on the detected temperature of the temperature detection parts T1-T5 becomes more than an estimated demand heat amount, a heating ventilation process is implemented. It is configured as follows. Thereby, when surplus heat is stored in the hot water storage tank 23 with respect to the predicted demand, the air blown into the bathroom M using the surplus heat is heated by the heat exchanger 9 for heating. Drying of the drying object in M can be promoted.

  Next, the operation state of the hot water supply device B in the non-heating air blowing process, the hot air drying process, and the heating air blowing process in the eco-drying operation will be described with reference to FIGS. In addition, the flow path shown with the thick line in FIGS. 5-7 shows the flow path which is in the state through which warm water flows.

[Non-heating blast treatment]
As shown in FIG. 5, in the non-heating air blowing process in the preliminary drying, the operation control unit C stops the operation of the fourth circulation pump P4 and stops the flow of the heat medium in the heating circulation path 8, That is, the heating heat exchanger 9 does not heat the air with the heated hot water heated by the heating unit 24 or the hot water stored in the hot water storage tank 23.

  Then, the circulation fan 6 and the exhaust fan 7 are actuated so that a part of the air sucked from the inside of the bathroom M is discharged to the outside through the exhaust duct 5, and the remaining air is blown into the bathroom M through the circulation ventilation path 18. Moreover, the operation control part C adjusts the direction of the movable louver 19 so that the blowing direction of the air into the bathroom M becomes the set blowing direction of the non-heating air blowing process in the eco-drying operation. The moisture can be removed from the dried object by the air blown into the bathroom M by the non-heated air blowing process.

  In the present embodiment, since the combined heat and power supply device 20 is always operating, as shown in FIG. 5, the first water circulation flow is passed through the first circulation path 31 and the second circulation path 32, so that the first The circulation pump P1 and the second circulation pump P2 are operated, and the three-way valves V1 and V2 are switched. Thereby, in the 1st heat exchanger 21, the warm water which circulates through the 2nd circulation path 32 is heated with the heat which the cooling water of the cogeneration apparatus 20 which circulates through the 1st circulation path 31 holds. Then, the hot water heated in the first heat exchanger 21 is stored in the hot water tank 23 from the second circulation path 32 through the first connection path 33.

[Hot air drying treatment]
As shown in FIG. 6, in the hot air drying process in the main drying, the operation control unit C operates the second circulation pump P2, the fourth circulation pump P4, and the heating unit 24, and switches the three-way valves V1 and V2. Thus, the hot water flows through the second circulation path 32 and the heating medium flows through the heating circulation path 8. That is, the heating heat exchanger 9 is heated by the heated hot water heated by the heating unit 24.

  Then, the circulation fan 6 and the exhaust fan 7 are operated, and a part of the air sucked from the bathroom M is discharged to the outside through the exhaust duct 5, and the remaining air is heated and circulated by the heat exchanger 9 for heating. It blows out into the bathroom M through the ventilation path 18. Moreover, the operation control part C adjusts the direction of the movable louver 19 so that the blowing direction of the air into the bathroom M becomes the set blowing direction of the hot air drying process. By this hot air drying process, moisture can be removed from the object to be dried by air heated using the heat of the heated hot water heated by the heating unit 24.

  In this embodiment, since the combined heat and power supply device 20 is always operating, as shown in FIG. 6, the first circulation pump P1 is operated so that the cooling water flows through the first circulation path 31. The Thereby, in the 1st heat exchanger 21, since the warm water which circulates through the 2nd circulation path 32 is heated with the heat which the cooling water of the cogeneration apparatus 20 which circulates through the 1st circulation path 31 holds, in the heating part 24 Heated hot water obtained by further heating the hot water circulating through the second circulation path 32 can be generated.

[Heat blowing treatment]
As shown in FIG. 7, in the heated air blowing process in the preliminary drying, the operation control unit C is configured by the second circulation path 32 and the second connection path 34 by operating the third circulation pump P3 and the fourth circulation pump P4. The hot water flows through the circulation path, and the heating medium flows through the heating circulation path 8. That is, the heating heat exchanger 9 is heated by the hot water stored in the hot water tank 23.

Then, the circulation fan 6 and the exhaust fan 7 are operated, and a part of the air sucked from the bathroom M is discharged to the outside through the exhaust duct 5, and the remaining air is heated and circulated by the heat exchanger 9 for heating. It blows out into the bathroom M through the ventilation path 18.
In the heating and blowing process, since the heating unit 24 is not operating, the heating heat exchanger 9 is not in a state of heating the air by the heated hot water heated by the heating unit 24.
Moreover, the operation control part C adjusts the direction of the movable louver 19 so that the blowing direction of the air into the bathroom M becomes the set blowing direction of the heated air blowing process. With this heating and blowing process, moisture can be removed from the object to be dried by air heated using the heat of hot water stored in the hot water storage tank 23.

  In this embodiment, since the combined heat and power supply device 20 is always operating, as shown in FIG. 7, the first circulation pump P1 and the second circulation pump P2 are operated, and the three-way valves V1 and V2 are switched. The hot water flows through the circulation path constituted by the first circulation path 31, the second circulation path 32, and the first connection path 33. Thereby, in the 1st heat exchanger 21, the warm water which circulates through the 2nd circulation path 32 is heated with the heat which the cooling water of the cogeneration apparatus 20 which circulates through the 1st circulation path 31 holds. Then, the hot water heated in the first heat exchanger 21 is stored in the hot water tank 23 from the second circulation path 32 through the first connection path 33. Thereby, the air heated by the heat exchanger 9 for heating can be blown out to the bathroom M using the heat of the hot water while heating the hot water stored in the hot water tank 23.

Next, the eco-drying operation will be described based on the flowchart shown in FIG.
In carrying out the eco-drying operation, a desired end desired time is input by the user from the desired end time input unit 42 of the remote controller R. When the user presses the eco dry operation switch 41 of the remote controller R, that is, when the remote controller R accepts the start of the eco dry operation, the remote controller R instructs the operation control unit C to start the eco dry operation. .

  When the remote controller R accepts the start of the eco-drying operation, the operation control unit C determines whether or not the period from the current time to the desired end time is longer than the set period (# 1). This determination is to determine whether the time for carrying out the eco-drying operation is sufficient, and the length of time from the current time to the desired end time is equal to or less than the set period. In some cases, this drying is carried out without carrying out preliminary drying.

  That is, in # 1, when the time from the current time to the desired end time is longer than the set period, the non-heating air blowing process is performed (# 2). And it is discriminate | determined whether heat sufficient conditions are satisfy | filled (# 3). In this embodiment, it is discriminate | determined whether the heat storage amount calculated | required by the temperature detected by temperature detection part T1-T5 which functions as a heat storage amount detection part is more than a setting heat storage amount.

  In # 3, when the sufficient heat condition is satisfied, that is, when the heat storage amount is equal to or greater than the set heat storage amount, the heated air blowing process is performed (# 5). If the sufficient heat condition is not satisfied in # 3, that is, if the heat storage amount is less than the set heat storage amount, it is determined whether or not it is the process switching time (# 4).

  In # 4, when it is not the process switching time, the non-heating air blowing process is continued (# 2).

  In step # 5, when the heated air blowing process is performed, it is determined whether or not a sufficient heat condition is satisfied (# 6). If the sufficient heat condition is satisfied, it is determined whether or not it is the process switching time (# 7). If the sufficient heat condition is not satisfied in # 6, the non-heating air blowing process is performed again (# 2).

  If the process switching time is not reached in # 7, the heated air blowing process is continued (# 5).

  Although not shown in FIG. 8, the operation control unit C delays the process switching time of # 7 toward the end desired time when the heating and blowing process of # 5 is performed. For example, the process switching time is delayed closer to the desired end time so that the time for performing the hot air drying process in # 7 is shortened by the time blown into the bathroom by the # 5 hot air blowing process.

  In # 1, if the time from the current time to the desired end time is equal to or shorter than the set period, and if it is the process switching time in # 4 and # 7, the hot air drying process is performed. (# 8). Next, the operation control unit C determines whether or not it is the desired end time (# 9). If it is not the desired end time, the hot air drying process is continued, and if the desired end time is reached, the hot air drying process is stopped and the eco-drying operation is terminated (# 9). . That is, the first, second, and fourth circulation pumps P1, P2, and P4 are stopped, the combustion of the heating unit 24 is stopped, and the exhaust fan 7 and the circulation fan 6 of the bathroom heating dryer A are stopped.

[Second Embodiment]

  In the second embodiment, the first connection path 33 and the second circulation path 32 form a loop-shaped flow path for circulating the hot water stored in the hot water tank 23. In this loop-shaped flow path, a connection circulation pump P6 is provided in the upper first connection path 33a, and a heating unit 24 and a second heat exchanger 22 are provided in the second circulation path 32.

  Further, the operation control unit C operates the heat collection circulation pump P5 when the amount of heat obtained by the solar water heater 50 is large, and stops the heat collection circulation pump P5 when the amount of heat obtained by the solar water heater 50 decreases. Specifically, when the temperature of the heat medium circulating through the heat collector circuit 51 detected by the circuit temperature detector 51A is equal to or higher than a predetermined set heat medium temperature, the heat collection circulation pump P5 is operated, When the temperature is lower than the set heat medium temperature, the heat collection circulation pump P5 is stopped.

In order to detect whether the temperature of the heat medium circulating in the heat collector circulation path 51 is equal to or higher than a predetermined set heat medium temperature in a state where the heat collection circulation pump P5 is stopped, the operation control unit C For example, the heat collection circulation pump P5 is configured to operate for a certain period of time every predetermined setting detection period.
As a result, when the amount of heat obtained by the solar water heater 50 is small, the temperature of the hot water in the hot water storage tank 23 is lowered by the low-temperature heat medium flowing through the tank heat exchanger 52. Can be prevented.

While a part of the air is discharged to the outside through the exhaust duct 5, the remaining air is blown into the bathroom M through the circulation ventilation path 18. Moreover, the operation control part C adjusts the direction of the movable louver 19 so that the blowing direction of the air into the bathroom M becomes the set blowing direction of the non-heating air blowing process in the eco-drying operation.
