JP 2002-126033 A

However, when the inside of a bathroom is dried by forcibly driving a ventilating fan in conjunction with an operation for terminating spraying of hot water, as in a conventional bathroom dryer with a mist function, for example, a plurality of users are short. Even when it is not necessary to dry the interior of the bathroom, such as when changing over time, there is a problem that the interior of the bathroom is dried, resulting in an increase in energy costs. That is, when it is used by a subsequent user, it is necessary to spray the hot water in the bathroom again to make it a humid space, so that the drying performed immediately before becomes useless, resulting in an increase in energy cost.

On the other hand, it seems that the above-mentioned problem can be solved by allowing the user to arbitrarily determine the start timing of drying in the bathroom. The start timing varies and the state in the bathroom at the start of drying in the bathroom (the amount of hot water in the bathroom) varies. That is, the amount of hot water remaining in the bathroom when drying in the bathroom is started varies depending on how much time has passed since the mist sauna mode was completed. That is, a large amount of hot water remains in the bathroom immediately after the mist sauna mode ends, but the hot water remaining in the bathroom also evaporates as time passes after the mist sauna mode ends. The amount of hot water in the water gradually decreases. In this way, if the user arbitrarily decides when to start drying in the bathroom, and the interior of the bathroom is dried in the same drying process, sometimes the drying in the bathroom will be insufficient, and sometimes the reverse. There is a problem in that drying in the bathroom becomes excessive, resulting in an increase in energy costs.

  Therefore, the present invention aims to provide a bathroom dryer with a mist function that can dry the interior of the bathroom reliably, reduce the total energy used for drying in the bathroom, and save energy and lower costs. To do.

According to a first aspect of the present invention, there is provided a spraying means for spraying hot water in the bathroom, a drying means for drying the bathroom, and a control means for controlling the spraying means and the drying means. Has a mist sauna mode in which the spraying means is operated and the inside of the bathroom is a humid space, and a bathroom drying mode in which the drying means is operated, and is selected from a plurality of operation modes including the mist sauna mode and the bathroom drying mode. An operation mode selection means capable of selecting a specific operation mode; and a storage means for storing a history of execution of the mist sauna mode. The control means selects the operation mode when the bathroom drying mode is selected. When the bathroom drying mode start signal transmitted from the means is received, the bathroom drying mode start signal is received within a predetermined first predetermined time period from the reception of the bathroom drying mode start signal. If the storage means stores that the time when the mist sauna mode is executed is less than the second predetermined time, the first bathroom drying control is performed to operate the drying means for a predetermined time. The storage means stores the fact that the time when the mist sauna mode was executed is not less than the second predetermined time within a period retroactive to the first predetermined time from when the bathroom drying mode start signal was received. If it is, the second bathroom drying control is performed, in which the drying means is operated for a longer time than the first bathroom drying control.

Even if the mist sauna mode has been executed before starting the drying in the bathroom, if a long time has passed from the end of the mist sauna mode to the start of the drying in the bathroom, spraying in the bathroom The hot and cold water that has been evaporated is considered to have no significant effect on the time required to dry the bathroom. In addition, even if the time elapsed from the end of the mist sauna mode to the start of drying in the bathroom is short, if the time during which the mist sauna mode has been executed is short, the amount of hot water sprayed in the bathroom is reduced. Even in this case, it is considered that the time required to dry the bathroom is not greatly affected.

  In the present invention, when the control means receives the bathroom drying mode start signal, the mist sauna mode is executed within a period of time that is predetermined for a predetermined first time from when the bathroom drying mode start signal is received. If the mist sauna mode is not executed or the time for which it is executed is less than the second predetermined time, it is determined that the amount of hot water remaining in the bathroom at that time is not large. Then, the first bathroom drying control for operating the drying means is executed only for the time necessary to dry the hot water remaining in the bathroom. On the other hand, when the time when the mist sauna mode is executed is not less than the second predetermined time within a period that is predetermined in advance from the time when the control means receives the bathroom drying mode start signal, While the mist sauna mode is being executed, a large amount of hot water is sprayed in the bathroom, and it is determined that a large amount of hot water still remains in the bathroom. The second bathroom drying control for operating the drying means is executed for a time necessary for drying (longer time than the first bathroom drying control). That is, when it is determined that the amount of hot water remaining in the bathroom is large when starting the bathroom drying mode, the time for operating the drying means is lengthened.

  In this way, by determining the amount of hot water remaining in the bathroom and changing the time for operating the drying means according to the amount of hot water, the bathroom can be reliably dried and The total energy used for drying can be reduced, saving energy and reducing costs.

The second aspect of the present invention relates to a bathroom dryer with a mist function according to the first aspect, and the second bathroom drying control is the most recent retroactive from the time when the bathroom drying mode start signal is received. A normal bathroom drying control and a bathroom drying mode start signal executed when the elapsed time from when the mist sauna mode ends to when the bathroom drying mode start signal is received is not less than a predetermined third predetermined time. Executed when the elapsed time from when the most recent mist sauna mode is completed retroactively to when the bathroom drying mode start signal is received is less than a predetermined third predetermined time. It is characterized by comprising energy-saving bathroom drying control for drying the interior of the bathroom using the remaining heat in the bathroom after the mode ends.

During the execution of the mist sauna mode, the floor and walls in the bathroom are heated by the sprayed hot water. Therefore, if there is not enough time between the end of the most recent mist sauna mode and the time when the control means receives the bathroom drying mode start signal, there is sufficient residual heat in the mist sauna mode on the floor or wall in the bathroom. This residual heat works well for drying hot water remaining in the bathroom. According to the present invention, it is determined that there is a lot of hot water remaining in the bathroom, and even when the second bathroom drying control for operating the drying means for a longer time than the first bathroom drying control is executed, the latest mist sauna mode is performed. If the elapsed time from the time when the bathroom drying mode start signal is received is less than the third predetermined time, it is determined that there is sufficient mist sauna mode residual heat on the floor or wall in the bathroom. Then, energy-saving bathroom drying control is performed to dry the interior of the bathroom by actively using the residual heat. Thereby, the inside of a bathroom can be dried with energy saving and low cost.

The third aspect of the present invention is the bathroom dryer with a mist function according to the second aspect, wherein the drying means dries the bathroom by supplying heated air into the bathroom. The energy-saving bathroom drying control is characterized in that the amount of heat applied to the air supplied to the bathroom by the drying means is controlled to be smaller than the normal bathroom drying control.

  If not much time has passed between the end of the most recent mist sauna mode and the time when the control means receives the bathroom drying mode start signal, there is sufficient residual heat in the mist sauna mode on the floor and walls in the bathroom. This residual heat can be used for drying in the bathroom. Therefore, according to the present invention, if the elapsed time from the end of the most recent mist sauna mode to the reception of the bathroom drying mode start signal is less than the third predetermined time, the remaining heat in the bathroom is dried. Compared with the normal bathroom drying control executed when the elapsed time is not less than the third predetermined time, the energy saving bathroom drying control executed at that time is determined to be usable, and the drying means is installed in the bathroom. The amount of heat applied to the supplied air is controlled to be small. Thereby, the energy used for drying in a bathroom can be reduced, and energy saving and low cost can be aimed at.

According to a fourth aspect of the present invention, there is provided a bathroom dryer with a mist function according to the second aspect, wherein the drying means exhausts the air in the bathroom and ventilates the bathroom. Therefore, the energy-saving bathroom drying control is characterized in that it controls the discharge speed of the air discharged by the drying means to be smaller than that of the normal bathroom drying control.

  If not much time has passed between the end of the most recent mist sauna mode and the time when the control means receives the bathroom drying mode start signal, there is sufficient residual heat in the mist sauna mode on the floor and walls in the bathroom. This residual heat can be used for drying in the bathroom. Therefore, according to the present invention, if the elapsed time from the end of the most recent mist sauna mode to the reception of the bathroom drying mode start signal is less than the third predetermined time, the remaining heat in the bathroom is dried. Compared with the normal bathroom drying control executed when the elapsed time is not less than the third predetermined time, the air discharged by the drying means is judged to be usable and the energy saving bathroom drying control executed at that time is compared with the normal bathroom drying control executed when the elapsed time is not less than the third predetermined time. The discharge speed is controlled to be small. Also, by reducing the discharge speed of the air discharged from the bathroom, a rapid temperature drop in the bathroom due to ventilation is prevented. Therefore, the loss of the residual heat by the rapid heat dissipation of the floor and wall in the bathroom is suppressed, and the bathroom can be dried using the residual heat for a long time. Thereby, the energy used for drying in a bathroom can be reduced, and energy saving and low cost can be aimed at.

According to a fifth aspect of the present invention, there is provided a bathroom dryer with a mist function according to the fourth aspect, further comprising temperature detection means for detecting the temperature in the bathroom, and the control means is an energy saving bathroom. In the case where the drying control is executed, when the temperature in the bathroom detected by the temperature detection means becomes lower than a predetermined temperature, the energy saving bathroom drying control is shifted to the bathroom drying control, and the drying means It is characterized by controlling so as to increase the discharge speed of the discharged air.

  As ventilation in the bathroom progresses, the temperature in the bathroom decreases and the residual heat on the floor and walls is lost. According to the present invention, when the temperature in the bathroom detected by the temperature detecting means for detecting the temperature in the bathroom is lower than a predetermined temperature, the residual heat of the floor or wall in the bathroom is not much dried. Since it is determined that it can no longer be used, the energy-saving bathroom drying control is shifted to the normal bathroom drying control so that the discharge speed of the air discharged by the drying means is increased. In other words, when the residual heat of the floor or wall in the bathroom can be used for drying, the air discharge rate is reduced by the drying means, and when the residual heat of the floor or wall in the bathroom becomes unavailable for drying, the drying means discharges The interior of the bathroom is dried by increasing the air discharge rate and ventilating the bathroom rapidly. Thereby, energy saving and low cost can be achieved, and the inside of the bathroom can be quickly dried.

  As described above, according to the bathroom dryer with a mist function of the present invention, the interior of the bathroom can be reliably dried, the total energy used for drying in the bathroom can be reduced, and energy saving and low cost can be achieved.

Thereafter, the “bathroom drying” switch of the operation panel 50 is operated (turned on) once at time T3, and the control unit 40 receives a signal of the “bathroom drying” switch (standard operation) from the operation panel 50. Standard operation in the drying mode is started. The execution time of the bathroom drying mode (standard operation) in this case is determined based on the time tm when the mist sauna mode is executed within 3 hours from the time T3 when the “bathroom drying” switch is operated (turned on). Is done. Specifically, the time tm when the mist sauna mode is executed within 3 hours from the time T3 when the “bathroom drying” switch is operated (turned on) is obtained by tm = T2−T1. And as shown in FIG. 12, when time tm when this mist sauna mode was performed is less than 10 minutes, bathroom drying mode is performed only for the preset standard time td. On the other hand, when the time tm when the mist sauna mode is executed is 10 minutes or more, it is determined that a large amount of hot water is sprayed in the bathroom 2 and the execution time of the bathroom drying mode is determined. Execute for a time td 'longer than the standard time td. Details will be described later with reference to FIG.

  Similarly, in the case 2 shown in FIG. 13, the time tm when the mist sauna mode is executed within 3 hours from the time T3 when the “dry bathroom” switch is operated (turned on) is tm = T2− ( T3-3h). And as shown in FIG. 13, when time tm when this mist sauna mode was performed is less than 10 minutes, bathroom drying mode is performed only for the preset standard time td. On the other hand, when the time tm when the mist sauna mode is executed is 10 minutes or more, it is determined that a large amount of hot water is sprayed in the bathroom 2 and the execution time of the bathroom drying mode is determined. Execute for a time td 'longer than the standard time td.

  In cases 1 and 2, if the mist sauna mode is executed a plurality of times within 3 hours retroactively from time T3, the sum of the execution times is set to tm. If the total time tm of the mist sauna mode is less than 10 minutes, the bathroom drying mode is executed for the preset standard time td, while the total time tm of the mist sauna mode is When it is 10 minutes or longer, it is determined that a large amount of hot water is sprayed in the bathroom 2 and the bathroom drying mode is executed for a time td ′ longer than the standard time td. In case 1 and case 2, the time for executing the bathroom drying mode is switched depending on whether or not the execution time tm of the mist sauna mode is 10 minutes or more. It can set suitably based on the spraying ability etc.

  12 and 13 describe the standard operation in the bathroom drying mode, but when the continuous operation in the bathroom drying mode is performed, as described above, until the end switch 404 is operated (turned on) by the user. The operation in the bathroom drying mode is continuously executed.

Next, a case where the bathroom drying mode (standard operation) is executed after the mist sauna mode is finished will be described with reference to FIG. In this case, the inside of the bathroom 2 can be dried by executing the bathroom drying mode (standard operation). FIG. 14 is a flowchart showing a procedure of operation control when the bathroom drying mode (standard operation) is executed after the mist sauna mode ends.

  First, in S1, the “mist sauna” switch of the operation panel 50 is operated (turned on) by the user at time T1, and the control unit 40 receives the signal of the “mist sauna” switch from the operation panel 50. Mist sauna mode is started. At this time, the memory 302 (storage means) stores the start time T1 of the mist sauna mode as a history of the execution of the mist sauna mode. Then, the mist sauna mode is executed, and the operation of the mist sauna mode ends at time T2 (S2). At this time, the memory 302 (storage means) stores the end time T2 of the mist sauna mode as a history of the execution of the mist sauna mode.

  Next, at S3, the user operates (turns on) the “bathroom drying” switch of the operation panel 50 once at time T3, and the control unit 40 operates the “bathroom drying” switch (standard operation) from the operation panel 50. By receiving the signal, the bathroom drying mode (standard operation) is started. At this time, the memory 302 (storage means) stores the start time T3 of the bathroom drying mode (standard operation) as a history of execution of the bathroom drying mode (standard operation). Then, due to S4, the damper 206 is driven to the branch position (the inlet of the exhaust duct 202 is half open (half open state)). Thereby, a part of the air sucked from the suction port 201 is discharged from the exhaust duct 202 to the outside of the bathroom 2, and another part of the air enters the bathroom 2 from the air outlet 203 provided in the grill plate 300. An air path is formed so as to be blown out (see FIG. 7).

  Next, in S5, it is determined whether or not T3-T2 is less than 3 hours using the mist sauna mode end time T2 stored in the memory 302 and the bathroom drying mode (standard operation) start time T3. The Here, when it is determined that T3-T2 is not less than 3 hours (NO), in other words, the mist sauna mode is executed within 3 hours from the start time T3 of the bathroom drying mode (standard operation). If it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time, the process proceeds to S8. On the other hand, when it is determined that T3-T2 is less than 3 hours (YES), in other words, the mist sauna mode is executed within 3 hours from the start time T3 of the bathroom drying mode (standard operation). If it is determined that the mist sauna mode is executed within 3 hours from the start time T3 of the bathroom drying mode (standard operation), the time tm is calculated (the calculation method is FIG. 12 and FIG. 13).

  Next, in S7, it is determined whether or not the time tm when the mist sauna mode is executed is 10 minutes or more within 3 hours from the start time T3 of the bathroom drying mode (standard operation). If it is determined that the time tm when the mist sauna mode is executed is not 10 minutes or more (NO), it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time. Proceed to S8.

  Then, the driving of the heating heater 205 (high output (high output)) is started in S8, and the driving of the heating / ventilation fan motor 208 (high rotation (high rotation speed)) is started in S9. Thereby, a part of the air sucked from the suction port 201 by the high-speed rotation of the heating ventilation fan 207 is discharged out of the bathroom 2 from the exhaust duct 202, and the other part of the air is heated by the heating heater 205, The air is blown into the bathroom 2 from the air outlet 203 provided in the grill plate 300. In S10, it is determined whether the standard time td has elapsed from time T3, in other words, whether the standard time td has elapsed since the bathroom drying mode was started. Until this, the process of S10 is executed. Then, when it is determined (YES) that the standard time td has elapsed since the bathroom drying mode was started, the process ends.

On the other hand, if it is determined in S7 that the time tm when the mist sauna mode is executed is 10 minutes or more (YES), a large amount of hot water is sprayed in the bathroom 2 while the mist sauna mode is executed. Therefore, it is determined that a large amount of hot water still remains in the bathroom 2, and in S11, the execution time of the bathroom drying mode is corrected to a time td ′ (correction time) longer than the standard time td. . The correction time td 'for the bathroom drying mode (standard operation) will be described later with reference to FIG.

Thus, the mist sauna mode is not executed or the mist sauna mode is executed within 3 hours from the time when the control unit 40 receives the start signal of the bathroom drying mode (standard operation) (time T3). However, if the executed time tm is less than 10 minutes, it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time and remains in the bathroom 2. The heater 205 and the heating / ventilation fan 207 are operated only for a time necessary for drying the hot water (standard time td). On the other hand, if the time for which the mist sauna mode has been executed is 10 minutes or more within 3 hours from the time when the control unit 40 receives the start signal of the bathroom drying mode (standard operation) (time T3), the mist A large amount of hot water is sprayed in the bathroom 2 while the sauna mode is being executed, and it is determined that a large amount of hot water still remains in the bathroom 2 and remains in the bathroom 2. The heating heater 205 and the heating / ventilation fan 207 are operated for a correction time td ′ necessary for drying the hot water (a time longer than the standard time td). That is, when it is determined that the amount of hot water remaining in the bathroom 2 is large when starting the bathroom drying mode (time T3), the time for operating the heating heater 205 and the heating ventilation fan 207 is lengthened. .

  Next, in S12, it is determined whether or not T3-T2 is less than 15 minutes using the mist sauna mode end time T2 stored in the memory 302 and the bathroom drying mode (standard operation) start time T3. The Here, when it is determined that T3-T2 is not less than 15 minutes (NO), in other words, the bathroom drying mode (standard operation) is started after 15 minutes or more have elapsed after the mist sauna mode is finished. In this case, it is determined that there is no residual heat in the mist sauna mode that can be used for drying on the floor or wall in the bathroom 2, and in this case, the bathroom drying control is normally performed. That is, similarly to S8 and S9, the driving of the heating heater 205 (high output (high output)) is started by S16, and the heating and ventilation fan motor 208 (high rotation (high rotation speed)) is driven by S17. Be started. In S15, it is determined whether the correction time td 'has elapsed from time T3, in other words, whether the correction time td' has elapsed since the start of the bathroom drying mode, and it is determined that it has not elapsed (NO). If it is determined that the correction time td ′ has elapsed (YES), the process ends.

On the other hand, when it is determined in S12 that T3-T2 is less than 15 minutes (YES), in other words, the bathroom drying mode (standard operation) is started within 15 minutes after the mist sauna mode is finished. If it is determined that there is sufficient residual heat in the mist sauna mode on the floor or wall in the bathroom 2, the residual heat is actively used to execute energy-saving bathroom drying control for drying the bathroom 2. . That is, driving of the heater 205 (low output (low output)) is started by S13, and driving of the heating / ventilation fan motor 208 (low rotation (low rotation speed)) is started by S14. Thus, in the energy-saving bathroom drying control, the output (heat amount) of the heater 205 and the number of rotations of the heating / ventilation fan motor 208 are controlled by positively using the residual heat in the mist sauna mode of the floor or wall in the bathroom 2. In addition, control is performed so as to be smaller than normal bathroom drying control (S16, S17), energy used for drying in the bathroom 2 is reduced, and energy saving and cost are reduced. In S15, it is determined whether the correction time td 'has elapsed from time T3, in other words, whether the correction time td' has elapsed since the start of the bathroom drying mode, and it is determined that it has not elapsed (NO). If it is determined that the correction time td ′ has elapsed (YES), the process ends.

  Next, a correction time td 'obtained by correcting the standard time td in the bathroom drying mode will be described. This correction time td 'is the time determined in the bathroom drying mode execution time correction process (S11) in FIG. FIG. 15 is a diagram illustrating the relationship between the time tm when the mist sauna mode is executed and the correction time td '.

  As shown in FIG. 15, the standard time td when the bathroom drying mode (standard operation) is executed is 2 hours. That is, in this embodiment, if the time tm when the mist sauna mode is executed is not more than 10 minutes within 3 hours from the start time T3 of the bathroom drying mode (standard operation), the bathroom drying mode is executed for 2 hours. Is done. The standard time td can be set by the operation remote controller 50 described above (see FIG. 3).

In addition, if the time tm when the mist sauna mode is executed is 10 minutes or more within 3 hours from the start time T3 of the bathroom drying mode (standard operation), this standard time is corrected and the bathroom drying mode is illustrated. The correction time shown in FIG. Specifically, when the time tm when the mist sauna mode is executed is within 10 hours and less than 20 minutes within 3 hours from the start time T3 of the bathroom drying mode (standard operation), the bathroom drying mode is set to 2. When the time tm when the mist sauna mode is executed for 2 hours (correction time td ′ = standard time td × 1.1) is 20 minutes or more and less than 30 minutes, the bathroom drying mode is 2.6 hours (correction time) td ′ = standard time td × 1.3) When the time tm when the mist sauna mode is executed is 30 minutes or more, the bathroom drying mode is 3.0 hours (correction time td ′ = standard time td × 1) .5) Performed. As described above, the correction time td 'is set to be longer according to the time tm when the mist sauna mode is executed within 3 hours from the start time T3 of the bathroom drying mode (standard operation).

The above describes the case where the bathroom drying mode (standard operation) is executed after the mist sauna mode is finished to dry the interior of the bathroom 2. Next, instead of the bathroom drying mode (standard operation), the mist sauna mode is finished. A case where the ventilation mode (standard operation) is executed later to dry the bathroom 2 will be described. FIG. 16 is a flowchart showing a procedure of operation control when the ventilation mode (standard operation) is executed after the mist sauna mode ends.

  First, in S21, the user operates (turns on) the “mist sauna” switch of the operation panel 50 at time T1, and the control unit 40 receives the signal of the “mist sauna” switch from the operation panel 50. Mist sauna mode is started. At this time, the memory 302 (storage means) stores the start time T1 of the mist sauna mode as a history of the execution of the mist sauna mode. Then, the mist sauna mode is executed, and the operation of the mist sauna mode ends at time T2 (S22). At this time, the memory 302 (storage means) stores the end time T2 of the mist sauna mode as a history of the execution of the mist sauna mode.

  Next, in S23, the user operates (turns on) the “ventilation” switch of the operation panel 50 once at time T3, and the control unit 40 outputs a signal of the “ventilation” switch (standard operation) from the operation panel 50. By receiving, ventilation mode (standard operation) is started. At this time, the start time T3 of the ventilation mode (standard operation) is stored as a history of the ventilation mode (standard operation) being executed by the memory 302 (storage means). In S24, the damper 206 is driven to the ventilation position (the inlet of the exhaust duct 202 is open (fully opened)). Thereby, an air path is formed so that all the air sucked from the suction port 201 is discharged out of the bathroom 2 from the exhaust duct 202 (see FIG. 5).

  Next, in S25, using the mist sauna mode end time T2 and the ventilation mode (standard operation) start time T3 stored in the memory 302, it is determined whether T3-T2 is less than 3 hours. . Here, when it is determined (NO) that T3-T2 is not less than 3 hours, in other words, the mist sauna mode is not executed within 3 hours from the start time T3 of the ventilation mode (standard operation). If it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time, the process proceeds to S28. On the other hand, when it is determined that T3-T2 is within 3 hours (YES), in other words, the mist sauna mode is executed within 3 hours from the start time T3 of the ventilation mode (standard operation). If it is determined, the process proceeds to S26, and the time tm when the mist sauna mode is executed is calculated within 3 hours from the start time T3 of the ventilation mode (standard operation) (the calculation method is shown in FIG. 12). And FIG. 13).

  Next, in S27, it is determined whether or not the time tm when the mist sauna mode is executed is 10 minutes or more within 3 hours retroactively from the start time T3 of the ventilation mode (standard operation). If it is determined that the time tm when the mist sauna mode is executed is not 10 minutes or more (NO), it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time. Proceed to S28.

  Then, the driving of the heating / ventilation fan motor 208 (high rotation (high rotation speed)) is started in S28. Thereby, all the air sucked from the suction port 201 by the high-speed rotation of the heating and ventilation fan 207 is discharged out of the bathroom 2 from the exhaust duct 202. In S29, it is determined whether the standard time tv of the ventilation mode (standard operation) has elapsed from time T3, in other words, whether the standard time tv has elapsed since the start of the ventilation mode. If it has been (NO), the process of S29 is executed until it elapses. Then, when it is determined (YES) that the standard time tv has elapsed since the start of the ventilation mode, the process ends.

On the other hand, when it is determined by S27 that the time tm when the mist sauna mode is executed is 10 minutes or more (YES), a large amount of hot water is sprayed in the bathroom 2 while the mist sauna mode is executed. Therefore, it is determined that a large amount of hot water still remains in the bathroom 2, and in S30, the execution time of the ventilation mode is corrected to a time tv ′ (correction time) longer than the standard time tv. The correction time tv 'for this ventilation mode (standard operation) will be described later with reference to FIG.

As described above, the mist sauna mode is not executed or the mist sauna mode is executed within 3 hours from the time when the control unit 40 receives the ventilation mode (standard operation) start signal (time T3). However, if the executed time tm is less than 10 minutes, it is determined that the amount of hot water remaining in the bathroom 2 is not large at that time, and the hot water remaining in the bathroom 2 is determined. The heating / ventilation fan 207 is operated only for a time necessary for drying (standard time tv). On the other hand, in the case where the mist sauna mode is executed for 10 minutes or more within 3 hours from the time when the control unit 40 receives the start signal of the ventilation mode (standard operation) (time T3), the mist sauna While the mode is being executed, a large amount of hot water is sprayed in the bathroom 2, and it is determined that a large amount of hot water still remains in the bathroom 2, and the hot water remaining in the bathroom 2 is determined. The heating / ventilation fan 207 is operated for a correction time tv ′ necessary to dry the air (longer than the standard time tv). That is, when it is determined that the amount of hot water remaining in the bathroom 2 is large when starting the ventilation mode (time T3), the time for operating the heating and ventilation fan 207 is lengthened.

  Next, in S31, it is determined whether or not T3-T2 is less than 15 minutes using the mist sauna mode end time T2 and the ventilation mode (standard operation) start time T3 stored in the memory 302. . Here, when it is determined that T3-T2 is not less than 15 minutes (NO), in other words, the ventilation mode (standard operation) is started after 15 minutes or more have elapsed from the end of the mist sauna mode. In this case, it is determined that there is no residual heat in the mist sauna mode that can be used for drying on the floor or wall in the bathroom 2, and in this case, normal ventilation control is executed. That is, similarly to S28, the driving of the heating / ventilation fan motor 208 (high rotation (high rotation speed)) is started by S34, and the flag F is set to “0” (F = 0) by S35.

On the other hand, if it is determined in S31 that T3-T2 is less than 15 minutes (YES), in other words, the ventilation mode (standard operation) is started within 15 minutes after the mist sauna mode is finished. In this case, it is determined that there is sufficient residual heat in the mist sauna mode on the floor or wall in the bathroom 2, and energy-saving bathroom drying control for drying the interior of the bathroom 2 is executed by actively using the residual heat. That is, the driving of the heating / ventilation fan motor 208 (low rotation (low rotation speed)) is started in S32, and the flag F is set to “1” (F = 1) in S33. As described above, in the energy-saving bathroom drying control, by actively using the residual heat in the mist sauna mode of the floor or wall in the bathroom 2, the rotation speed of the heating / ventilation fan motor 207 is set to the normal bathroom drying control (S28). Control is performed so as to be smaller in comparison. Thereby, the energy used for drying in the bathroom 2 can be reduced, and energy saving and low cost can be aimed at. Moreover, the rapid fall of the temperature in the bathroom 2 by ventilation is prevented by making small the discharge speed | rate of the air discharged | emitted from the bathroom 2 inside. Therefore, rapid heat dissipation of the floor and walls in the bathroom 2 is suppressed, and the bathroom 2 can be dried using the residual heat for a long time.

Next, in S36, it is determined whether the correction time tv 'has elapsed from time T3, in other words, whether the correction time tv' has elapsed since the start of the ventilation mode. And when it is judged that it has not passed, it progresses to S37. If it is determined in S36 that the correction time tv 'has elapsed (YES), the process ends.

Next, in S37, it is determined whether or not the flag F is “1”. If it is determined in S37 that the flag F is “1” (YES), that is, if it is determined that the energy-saving bathroom drying control is being executed, the process proceeds to S38. If it is determined in S37 that the flag F is not “1” (NO), that is, if it is determined that the normal bathroom drying control is being executed, the process proceeds to S36, and the corrected time tv from time T3 again. It is determined whether 'has elapsed.

In S38, it is determined whether or not the temperature in the bathroom 2 is less than 30 degrees. The temperature in the bathroom 2 is detected by a temperature sensor 209. If it is determined in S38 that the temperature in the bathroom 2 is less than 30 degrees (YES), the process proceeds to S39, where the rotation speed of the heating / ventilation fan motor 208 is increased from a low rotation speed (low rotation speed) to a high speed. Changed to rotation (high rotation speed). As described above, when it is determined that the temperature in the bathroom 2 is less than 30 degrees, it is determined that the residual heat of the floor or wall in the bathroom 2 is not much available for drying in the bathroom 2, and energy-saving bathroom drying is performed. Control is shifted to normal bathroom drying control, and the bathroom 2 is rapidly ventilated to speed up drying. If it is determined by S38 that the temperature in the bathroom 2 is not less than 30 degrees (NO), it is determined that the residual heat of the floor and walls in the bathroom 2 can still be used for drying in the bathroom 2, and S36 Then, it is determined again whether or not the correction time tv ′ has elapsed from time T3.

When shifting from the energy saving bathroom drying control to the normal bathroom drying control, the flag F is changed from “1” to “0” in S40. Then, after F = 0, the process proceeds to S36, where it is determined again whether or not the correction time tv ′ has elapsed from time T3, and until the correction time tv ′ has elapsed from time T3, S36 → S37 → S36. The process is executed.

  Next, the correction time which corrected the standard time of ventilation mode is demonstrated. This correction time is the time determined in the ventilation mode execution time correction process (S30) of FIG. FIG. 17 is a diagram illustrating the relationship between the time tm when the mist sauna mode is executed and the correction time tv ′ of the ventilation mode (standard operation).

  As shown in FIG. 17, the standard time tv when the ventilation mode (standard operation) is executed is 3 hours. That is, in this embodiment, if the time tm when the mist sauna mode is executed is not more than 10 minutes within 3 hours retroactively from the start time T3 of the ventilation mode (standard operation), the ventilation mode is executed for 3 hours. . The standard time tv can be set by the operation remote controller 50 described above (see FIG. 3).

If the time tm when the mist sauna mode is executed is 10 minutes or more within 3 hours from the start time T3 of the ventilation mode (standard operation), the standard time is corrected, and the ventilation mode is shown in FIG. The correction time shown is executed. Specifically, when the time tm when the mist sauna mode is executed is within 10 hours and less than 20 minutes within 3 hours from the start time T3 of the ventilation mode (standard operation), the ventilation mode is 3.9 hours. (Correction time tv ′ = standard time tv × 1.3) When the time tm when the mist sauna mode is executed is 20 minutes or more and less than 30 minutes, the ventilation mode is 4.5 hours (correction time tv ′ = When the time tm when the mist sauna mode is executed is 30 minutes or more, the ventilation mode is 5.1 hours (correction time tv ′ = standard time tv × 1.7). Is done. As described above, the correction time tv 'is set to become longer according to the time tm when the mist sauna mode is executed within 3 hours from the start time T3 of the ventilation mode (standard operation).
