As shown in FIG. 1, the bathroom 1 includes a bathtub 2 and a washing place 3, a ceiling surface 4 has an inspection port 5 and an opening 6, and a body 7 that forms a bathroom heating dryer is disposed in the opening 6. Yes.

  As shown in FIG. 2, a main body 7 is provided in the ceiling space 8 of the bathroom 1 and communicates with the bathroom 1 through the opening 6. The inspection port 5 is located directly above the washing area, and the opening 6 is located directly above the bathtub 2.

  Moreover, the panel 9 of a bathroom heating dryer faces the bathroom 1, and is provided with the suction inlet 10 and the blower outlet 11. FIG.

  The main body 7 includes a heat exchanger 12 using hot water as air heating means for heating air taken in from the suction port 10 and a circulation fan motor 13 as circulation fan means for circulating air. When the motor 13 is driven, the air taken from the suction port 10 is overheated by the heat exchanger 12 and becomes hot air. The warm air passes through the ventilation path 14 and reaches the air outlet 11 that blows air into the bathroom 1 by the circulation fan motor 13. Further, the warm air is moved in an arbitrary direction of the bathroom 1 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, as a means for operating the wind direction plate 15. Can blow.

  In the first embodiment, the main body 7 may be provided with humidifying means that can make the bathroom 1 into a sauna space.

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

  Further, a ventilation unit 17 having a ventilation fan motor 16 as a ventilation means for discharging the air of the bathroom 1 to the outside is provided outside the main body 7 of the bathroom heater / dryer, and the ventilation unit 17 and the main body 7 are opened to communicate with each other. 18 is provided. The opening 18 includes a damper 19 that adjusts the size of the opening 18 so that the bathroom 1 can be ventilated.

  The damper 19 may not be provided.

  In addition, the structure which the ventilation part 17 equips with the inside of the main body 7, or communicates with the main body 7 via duct piping may be sufficient.

  The main body 7 includes an electrical board 20 as operation control means for controlling operation, a dressing room remote controller 22 as operation means for operating the main body 7 from the dressing room 21 and displaying the operation state, and the main body 7 as a bathroom. And a bathroom remote controller 23 as an operation means for operating from 1 and displaying the driving state. The operation of the main body 7 can be performed by an operation from the dressing room remote controller 22 or the bathroom remote controller 23.

  The body 7 is provided with a bathroom temperature sensor 24 and a bathroom humidity sensor 25 in the vicinity of the suction port 10, and when either or both of the circulation fan motor 13 and the ventilation fan motor 16 are driven, the air passing through the suction port 10. Temperature and humidity can be detected.

  Moreover, the dressing room 21 is equipped with the dressing room temperature sensor 26, and the temperature of the dressing room 21 can be detected. The dressing room temperature sensor 26 can also be installed inside the dressing room remote controller 22, thereby facilitating the construction.

  Next, the ventilation operation by the said structure is demonstrated.

  When a large amount of moisture is generated in the bathroom 1 due to bathing or the like, the ventilation fan motor 16 is driven by pressing the ventilation operation switch of the dressing room remote controller 22 or the bathroom remote controller 23, and the bathroom 1 taken in from the inlet 10 Exhaust air containing a large amount of moisture outdoors.

  At this time, air that does not contain as much moisture as the air exhausted from the bathroom 1 flows from the dressing room 21 into the bathroom 1 through a gall (not shown) provided on the door of the bathroom 1.

  As a result, the moisture generated in the bathroom 1 is discharged to the outside, and there is an effect such as prevention of mold stains in the bathroom 1.

  Next, the automatic stop of the ventilation operation will be described.

  When the ventilation operation is performed, the temperature and humidity in the bathroom 1 that has risen due to bathing or the like gradually decrease. Therefore, as a method of automatically stopping the ventilation operation, for example, there is a method of stopping when the humidity in the bathroom 1 becomes a predetermined value or less.

  However, in this method, how much the humidity decreases depending on the humidity of the dressing room 21 flowing into the bathroom 1, and the humidity of the air in the dressing room 21 flowing into the bathroom 1 is, for example, the air conditioning of the dressing room 21. When the on / off operation is performed or when the opening / closing of the window of the dressing room 21 is changed greatly, there is a problem that the accuracy of the moisture discharge completion determination is low.

  As a highly accurate method of automatic stop of the ventilation operation, the completion of the discharge of the moisture in the bathroom 1 is all exhausted, that is, all the air containing a large amount of moisture that was in the bathroom 1 at the start of the ventilation operation. There is a method of detecting that the air inside is replaced with the air in the dressing room 21.

  Specifically, the automatic stop timing is when the temperature in the bathroom 1 and the temperature in the dressing room 21 are equal, and the humidity in the bathroom 1 and the dressing room 21 are equal.

  The automatic stop determination device for ventilation operation provided on the electrical board 20 of the bathroom heating / drying machine of the present invention detects the temperature and humidity of the air in the bathroom 1 and the temperature of the air in the dressing room 21. When the temperature of the air in the bathroom 1 is equal to the temperature of the air in the dressing room 21 and the amount of change in the humidity of the air in the bathroom 1 over a certain period of time is below a certain value, the humidity of the air in the bathroom 1 It is determined that the humidity of the air in the dressing room 21 has become equal, and the ventilation operation is automatically stopped.

  The temperature in the bathroom 1 is detected by a value detected by the bathroom temperature sensor 24 as a means for detecting the temperature in the bathroom 1 and by a dressing room temperature sensor 26 as a means for detecting the temperature of the dressing room 21. Use the specified value.

  The humidity is a value detected by the bathroom humidity sensor 25 as a means for detecting the humidity in the bathroom 1 and the amount of change in a certain time (for example, about 30 minutes) is less than a certain value (for example, about 10%). If there is, it can be determined that the humidity in the bathroom 1 and the humidity in the dressing room 21 are equal.

  The humidity may be either relative humidity or absolute humidity.

  Further, a certain time (for example, about 30 minutes) may be provided between the time when the ventilation operation is determined to be stopped by the automatic stop determination device and the time when the ventilation operation is stopped.

  Thereby, the moisture in a bathroom can be discharged | emitted reliably.

  The bathroom heater / dryer according to the present invention makes it possible to correctly determine the timing for automatically stopping the ventilation operation even when the temperature and humidity of the air sucked into the bathroom fluctuates in the automatic stop of the ventilation operation. It is useful as a bathroom heating dryer with low energy consumption used in the bathroom.
