That is, the water mist operation start command 43f of the touch panel type information input unit 43 of the smartphone P is touch-operated to command the water mist operation start command, and the water mist operation start command commanded from the kitchen remote control 1 is the smartphone P. Corresponds to the case of the water mist operation start command transmitted from.

Further, the bath drying control means 6 is based on the detection information of the humidity sensor 34 when the water mist operation start command commanded from the kitchen remote controller 1 is the water mist operation start command transmitted from the smartphone P, and the bathroom 101 When the estimated mist spraying impossible state, which is presumed that mist should not be sprayed, is detected, the first mist spraying impossible estimation information corresponding to the mist spraying impossible estimation state is transmitted to the kitchen remote controller 1. ing.
Further, when the kitchen remote controller 1 receives the first mist spray impossible estimation information transmitted from the bath drying control means 6, the kitchen remote controller 1 transmits the second mist spray impossible estimation information corresponding to the first mist spray impossible estimation information to the smartphone P. It is configured to do.
When the smartphone P receives the second mist spray impossible estimation information transmitted from the kitchen remote controller 1, the smartphone P cannot spray mist indicating that the mist should not be sprayed into the bathroom 101 as shown in FIG. The water mist operation start selection screen 47 including the information 47a is displayed on the display surface 41 by the image display means 42, and the touch panel type information input unit 43 is forced to start the water mist operation for forcibly starting the water mist operation. It is configured to operate in a state in which an operation for transmitting a command to the kitchen remote controller 1 is possible.
Then, when the kitchen remote controller 1 receives the water mist operation forced start command transmitted from the smartphone P, the bath-drying control means 6 operates the circulation fan 2 and the ventilation fan 3, and also operates the upstream mist. The solenoid valve 12 and the solenoid valve 13 for downstream mist are opened (that is, the mist means M is operated) to forcibly start the water mist operation.

As shown in FIG. 4, on the water mist operation start selection screen 47, the text information "during bathing or drying" is displayed as a specific example of the mist spray impossible information 47a.
Further, on the water mist operation start selection screen 47, a text information such as "Do you want to start the water mist operation?" Is displayed to ask whether or not the water mist operation is forcibly started. Water mist operation forced start selection information 47b is displayed, and further, "Yes" and "No" icons are displayed below the water mist operation forced start selection information 47b, and the area of the "Yes" icon is water. The water mist operation forced start switch 43h that commands the mist operation forced start command is set, and the area of the “No” icon is the water mist operation cancel switch 43i that cancels the water mist operation command.
That is, the image display means 42 displays the water mist operation start selection screen 47 on the display surface 41, and the touch panel type information input unit 43 is provided with the water mist operation forced start switch 43h. Is equivalent to operating in a state in which an operation for transmitting a water mist operation forced start command to the kitchen remote controller 1 is possible.

The bath-drying control means 6 increases the relative humidity detected by the humidity sensor 34 after the ventilation fan 3 operates (degree of increase) with respect to the relative humidity detected by the humidity sensor 34 before the ventilation fan 3 operates. When the setting width (an example of the setting degree) is less than the set width (an example of the setting degree), the mist spray permissible estimated state is detected, and when the increase width is equal to or more than the set width, the mist spray impossible estimated state is detected. ing.

Next, the results of an experiment will be described below in order to make it possible to detect whether the mist spraying allowable estimated state or the mist spraying impossible estimated state is detected by the fluctuation of the relative humidity detected by the humidity sensor 34.
When a person is bathing in the bathroom 101, the relative humidity detected by the humidity sensor 34 before the operation of the ventilation fan 3 is 51%, but one minute has passed after the operation of the ventilation fan 3. At that time, the relative humidity detected by the humidity sensor 34 increased to 90%.
On the other hand, when no one is bathing in the bathroom 101, the relative humidity detected by the humidity sensor 34 before the operation of the ventilation fan 3 is 47%, and one minute after the operation of the ventilation fan 3 After a lapse of time, the relative humidity detected by the humidity sensor 34 remained at 47%.

Although detailed description is omitted, even when the laundry is dried in the bathroom 101, the relative humidity detected by the humidity sensor 34 is higher after the ventilation fan 3 is operated than before the ventilation fan 3 is operated. Was higher.
Incidentally, when a person is taking a bath in the bathroom 101 or when the laundry is dried in the bathroom 101, the mist should not be sprayed in the bathroom 101.

That is, since the air in the bathroom 101 is not ventilated to the humidity sensor 34 before the ventilation fan 3 is operated, the relative humidity detected by the humidity sensor 34 is the bathroom heating / drying isolated from the inside of the bathroom 101. It is the relative humidity of the air in the casing 7 of the part D.
On the other hand, after the ventilation fan 3 is operated, the air in the bathroom 101 is ventilated to the humidity sensor 34, so that the relative humidity detected by the humidity sensor 34 is the relative humidity of the air in the bathroom 101. ..
Therefore, the mist spray permissible estimation is based on the relative humidity detected by the humidity sensor 34 before the operation of the ventilation fan 3 and the relative humidity detected by the humidity sensor 34 after the operation of the ventilation fan 3. It is possible to detect whether it is a state or an estimated state where mist spraying is not possible.

Then, in this embodiment, the set time is set to, for example, 1 minute, and the set width is set to, for example, 5% in relative humidity.

Next, among the control operations of the bath-drying control means 6, the control operation for realizing the control when the water mist operation start command is commanded from the smartphone P described above will be described based on the flowchart shown in FIG. Add.

Subsequently, the ventilation fan 3 is operated (steps # 1 to 3).

After the ventilation fan 3 is operated in step # 3, the bath-drying control means 6 reads the detection data (relative humidity) of the humidity sensor 34 from the time when the ventilation fan 3 is operated until the set time elapses. The increase width of the detection data (relative humidity) of the humidity sensor 34 after the operation of the ventilation fan 3 is greater than or equal to the set width with respect to the detection data (relative humidity) of the humidity sensor 34 before the operation of the ventilation fan 3. It is determined whether or not this is the case (steps # 4 to 6).
Then, when the rise width of the detection data of the humidity sensor 34 does not exceed the set width between the time when the ventilation fan 3 is operated and the set time elapses, that is, when the rise width is less than the set width. The mist spray permissible estimation state is detected (step # 7), and when the increase width of the detection data of the humidity sensor 34 exceeds the set width, the mist spray non-permissible estimation state is detected (step # 10).
When the bath-drying control means 6 detects the mist spray permissible estimation state in step # 7, it starts the water mist operation, transmits the "operation reception signal" to the smartphone P via the kitchen remote controller 1, and returns, that is, , Proceed to the main control routine waiting for a command from the kitchen remote controller 1 etc. (steps # 8 and 9).

By the way, when the smartphone control means 45 of the smartphone P receives the "operation reception signal" transmitted from the bath drying control means 6, it indicates that the water mist operation in which the start command has been executed has been executed by the image display means 42. The "operation executed information" is displayed on the display surface 41. As the "operation executed information", for example, on the remote control operation screen 46 displayed on the display surface 41, a display such as changing the color of the icon corresponding to the water mist operation or blinking the icon is executed.

When the bath-drying control means 6 detects the mist spray impossible estimation state in step # 10, it transmits the first mist spray impossible estimation information to the kitchen remote controller 1, and after the transmission, issues a water mist operation forced start command from the smartphone P. When it is received, the process proceeds to step # 8, while when the water mist operation cancel command from the smartphone P is received, the process returns as it is (steps # 11 to 13).
By the way, when the process proceeds to step # 8, the water mist operation is started, the "operation reception signal" is transmitted to the smartphone P via the kitchen remote controller 1, and the device returns (steps # 8 and 9).

When the kitchen remote controller 1 receives the first mist spray impossible estimation information from the bath drying control means 6, it transmits the second mist spray impossible estimation information corresponding to the first mist spray impossible estimation information to the smartphone P.
When the smartphone control means 45 of the smartphone P on which the remote control application is running receives the second mist spray impossible estimation information from the kitchen remote control 1, the water mist operation start selection screen 47 (see FIG. 4) is displayed by the image display means 42. It is displayed on the display surface 41.
When the user executes the water mist operation even though the display surface 41 of the smartphone P displays information such as "during bathing or drying" as a specific example of the mist spray impossible information 47a. Touch-operates the "Yes" icon (that is, the water mist operation forced start switch 43h) on the display surface 41 of the smartphone P, while "No" on the display surface 41 of the smartphone P when the water mist operation is not executed. ”Icon (that is, the water mist operation cancel switch 43i) is touch-operated.

When the water mist operation forced start switch 43h is touch-operated by the user, the smartphone control means 45 of the smartphone P transmits a water mist operation forced start command to the kitchen remote controller 1, and the water mist operation cancel switch 43i is operated by the user. When the touch operation is performed, a water mist operation cancel command is transmitted to the kitchen remote controller 1.
