When the circulation fan motor 13 is driven, the air taken in from the suction port 10 is heated by the heat exchanger 12 to become hot air. The warm air passes through the ventilation path 14 that connects the circulation fan motor 13 to the air outlet 11 that blows air into the bathroom 1 and reaches the air outlet 11.

  Further, the warm air is supplied by a wind direction plate 15 as a wind direction control means for changing the direction of the air blown from the air outlet 11, and a motor, preferably a stepping motor (not shown), as a means for operating the wind direction plate 15. The air can be blown in any direction of the bathroom 1.

  As the circulation fan motor 13, for example, a sirocco fan is used as a fan and a DC is used as a motor.

  In the first embodiment, the body 8 of the bathroom heater / dryer may be provided with humidifying means that can make the bathroom 1 a sauna space.

  In the first embodiment, the heat exchanger 12 using hot water is used as the air heating means, but other electric heaters such as a PTC heater, a halogen heater, and a sheathed heater may be used instead of the heat exchanger 12.

  The bathroom heater / dryer is provided by screwing a ventilation unit 17 provided with a ventilation fan motor 16 as a ventilation means for discharging the air of the bathroom 1 to the outside outside the inspection port 5 side of the main body 8. The damper 17 which adjusts the opening shape (equivalent to opening area) which connects the part 17 and the main body 8, and can communicate can be ventilated.

  In addition, the structure which connects the external heating apparatus and bathroom heating dryer via a duct piping may be sufficient without the damper 18 and having the ventilation means in the main body 8 inside.

  The bathroom heating / drying machine includes an electrical board 19 as operation control means for controlling operation, and a dressing room remote controller 21 as operation means for operating the bathroom heating / drying machine from the inside of the dressing room 20 to display the operation state. And a bathroom remote controller 22 as an operation means for operating the bathroom heater / dryer from the bathroom 1 and displaying the operation state, and operating the bathroom heater / dryer by operations from the dressing room remote controller 21 and the bathroom remote controller 22. Can do.

  The bathroom heater / dryer includes a temperature sensor 23 as a bathroom temperature detection means and a humidity sensor 24 as a humidity detection means, and the temperature of the bathroom 1 is determined from the temperatures detected by the temperature sensor 23 and the humidity sensor 24.

The microcomputer is generally called a microcomputer and controls the operation of the bathroom heating dryer. The microcomputer is provided in the dressing room remote controller 21 or the bathroom remote controller 22 and controls the operation of the bathroom heating dryer by communication. It suffices that at least one component is mounted on the electrical board 19, the dressing room remote controller 21 or the bathroom remote controller 22, and there is no problem even if it is mounted at a plurality of locations.

  In addition, communication does not limit communication forms, such as a wired line and wireless.

  The temperature sensor 23 may be a thermistor sensor, an infrared sensor, or other various temperature sensors, and the humidity sensor 24 may be calculated from a relative humidity, a resistance change value, or a current change value, and directly calculates the absolute humidity. As long as it is obtained, the computation can be omitted.

  Note that it is preferable that the temperature sensor and the humidity sensor be provided at positions close to each other because the absolute humidity can be calculated with little error with respect to temperature unevenness in the space, and may be integrated.

  As shown in FIG. 3, an operation mode for drying clothes after washing or bathing in the bathroom 1 by operating the bathroom remote controller 22 or the dressing room remote controller 21, such as clothes drying operation, bathroom drying operation, etc. is started. Then, the wind direction plate 15 becomes an angle A0 set by the user (user) for each operation mode, and the setting of the angle A0 is selected by the user from several preset angles set in advance. Generally, it is set for a dry object.

  The angle is an angle on the washing space 3 side between the ceiling surface 4 and the wind direction plate 15.

  Further, the user can set the driving time T0 of the driving mode, that is, the driving end time (for example, the driving duration can be set every 10 minutes up to a minimum time of 10 minutes and a maximum of 6 hours).

  When the circulation fan motor 13 is operated, the air sucked from the suction port 10 reaches the blower outlet 11 through the heat exchanger 12 and the ventilation path 14 and is blown out to the bathroom 1 at an angle A0 determined by the wind direction plate 15.

The air in the bathroom 1 containing the hydrated water is discharged outdoors.

  At that time, the air volume blown into the bathroom and the air volume discharged to the outside are the initial setting value Q0 of the air volume to be blown preset in each operation mode and the initial setting value Q1 of the air volume discharged to the outdoors. .

After that, the object to be dried in the bathroom 1 gradually dries, but there is a difference in the drying state of the object to be dried due to the installation condition of the bathroom heating dryer, the size of the bathroom 1, the temperature and humidity of each season, etc. Yes,
Drying may occur at the time set by the user.

  While the drying operation is continued, the absolute humidity in the bathroom is calculated from the values detected by the temperature sensor and the humidity sensor at the time T1 (for example, 5 minutes) before the end of the operation time set by the user. The state of the object to be dried is determined based on the moisture content of the bathroom air, that is, the absolute humidity threshold of the bathroom air.

  When it is determined that the absolute humidity in the bathroom 1 is small, the operation is continued with the operation time T0 set by the user as the operation end time, and the operation is ended when the time T0 has elapsed from the start of the operation.

  When it is determined that the absolute humidity in the bathroom 1 is high, the predetermined operation time T2 (for example, 30 minutes) is extended with respect to the operation time T0 set by the user.

  Note that the same determination is made at the time T1 before the end of the operation after extending the operation time T2.

  Further, the extension of the operation time may be provided with means for forcibly terminating the operation by the accumulated time (for example, the operation continuation by extension is 24 hours).

  Note that it is possible to set the operation time not to be extended as described above.

  In addition, an operation in the case where the air volume is changed as means for drying an object to be dried within the operation time set by the user when the absolute humidity in the bathroom 1 is determined to be small will be described.

  As shown in FIG. 4, after a certain time T1 (for example, 30 minutes or half of the set operation time) has elapsed after the start of operation, the absolute humidity calculation in the bathroom is performed based on the values detected by the temperature sensor and the humidity sensor, and determined in advance. The state of the object to be dried is determined based on the amount of moisture in the bathroom air, that is, the absolute humidity threshold of the bathroom air.

  If it is determined that the absolute humidity in the bathroom 1 is low, the operation is continued without changing the initial circulating air volume Q0, and the operation is terminated when T0 time has elapsed from the start of the operation.

  When it is determined that the absolute humidity in the bathroom 1 is high, the air flow is increased to a predetermined circulation air flow Qmax (for example, 300 m3 / h or more) with respect to the initial circulation air flow Q0, and T0 time has elapsed from the start of operation. When you do so, stop driving.

  Note that it is also possible to set the air volume not to increase as described above.

  The operation in the case of storing the absolute humidity in the bathroom 1 before the start of operation, that is, the initial moisture amount in the bathroom 1, and using the initial moisture amount as a threshold value for determining the dry state of the object to be dried will be described.

  As shown in FIG. 5, the absolute humidity in the bathroom is calculated from the values detected by the temperature sensor and the humidity sensor at t0 (for example, 30 minutes before the start) before the start of operation. The initial moisture amount is set as a threshold for determining the state of the dry object. And since a user starts arbitrarily, the said initial moisture content is memorize | stored in time series.

  The initial moisture amount may be configured such that a value after a certain period (for example, 24 hours) is erased from the stored value.

  While the drying operation is continued, the absolute humidity in the bathroom is calculated from the values detected by the temperature sensor and the humidity sensor at the time T1 (for example, 5 minutes) before the end of the operation time set by the user. The state of the dry object is determined from the amount of moisture in the bathroom air at T1.

  If it is determined that the amount is smaller than or equal to the initial moisture content, the operation is continued with the operation time T0 set by the user as the operation end time, and the operation is terminated when the time T0 has elapsed from the start of operation.

  If it is determined that the amount of water is greater than the initial moisture content, a predetermined operation time T2 (for example, 30 minutes) is extended with respect to the operation time T0 set by the user.

  Note that the same determination is made at the time T1 before the end of the operation after extending the operation time T2.

  Further, the extension of the operation time may be provided with means for forcibly terminating the operation by the accumulated time (for example, the operation continuation by extension is 24 hours).

  Note that it is possible to set the operation time not to be extended as described above.

  In addition, the absolute humidity in the bathroom is calculated from the value detected by the sensor at the time T1 before the end of operation (for example, 5 minutes) for the operation time set by the user, and the amount of moisture in the bathroom air in T1 before the end of operation is calculated. A configuration may be adopted in which the state of the drying object is determined according to the difference from the initial moisture content, and a stage is provided for the extended operation time T2.

  The bathroom heating / drying machine according to the present invention has a function for drying an object to be dried and a target space, and can be applied to a device having a function of setting an operation time from a device operation unit.
