  In the ventilation mode of FIG. 4D, the fan motor 27 stops and the fan motor 32 rotates. The motor of the door portion 25 closes the suction opening 18 and opens the circulation opening 19. The motor of the door portion 36 blocks the air flow path on the duct 5 side and opens the air flow path on the suction port 34 side. The heater 30 is turned off by de-energization. As a result, the high-humidity air inside the bathroom 9 is sucked into the bathroom ventilator 1 from the suction port 34, blown into the duct 6 by the exhaust system fan 33, and exhausted to the outside. Air is supplied from the dressing room through the vent.

  In the above-described bathroom drying mode and clothes drying mode, the amount of air supplied from other rooms is equal to the amount of bathroom air discharged, and bathroom air does not flow from the garage 41 to other rooms such as a dressing room. It is like that.

  In addition, a cool breeze mode used in summer, etc. may be provided in the operation mode, and the air in the bathroom may be exhausted while circulating the air in the bathroom or supplying the air in another room with the heater OFF. . Furthermore, although the other room has been described as a dressing room, it may be a room other than the dressing room, or it may be outside air. The heater 30 may be a heat exchanger or any other heating means that heats the air. Furthermore, the bathroom drying mode may be used as an energy-saving clothing drying mode that does not use the heater 30, or the heater 30 may be turned on with the clothing drying mode as a rapid bathroom drying mode.

  Next, the structure of the louver 41 provided in the door 42 (see FIG. 3) of the bathroom 9 will be described with reference to FIGS. The bathroom gallery 41 forms a vent for introducing air such as a dressing room or a corridor. The louver 41 is formed by arranging draining plates 43 (see FIGS. 6A and 6B) extending in the horizontal direction in a lattice shape in the vertical direction, and a gap between the upper and lower draining plates 43 serves as a vent 43A. The draining plate 43 of the louver 41 is inclined such that the edge on the bathroom 9 side is low and the edge on the dressing room side is high so that water drops fall on the washing place side of the bathroom 9. The front edge portion 43B and the rear edge portion 43C of the draining plate 43 extend in the vertical direction so that water drops that have passed through the vent hole 43A do not fall to the dressing room side.

  The gallery 41 is provided with a gallery opening / closing device 44. This gallery opening / closing device 44 constitutes a bathroom air-conditioning system together with the above-described bathroom air-conditioning device 1, and vertically extends along a guide plate 45 having a substantially L-shaped horizontal section and a front edge portion 43 </ b> B of the draining plate 43. The frame 46 includes a slidable frame 46, a shielding plate 47 for closing the gap 43 </ b> A, a rack 48 attached to a side surface of the frame 46, a pinion 49, and a motor 50.

  The guide plate 45 is provided at the left and right edge portions of the louver 41 and is fixed so as to extend in the vertical direction. The frame part 46 is formed in a rectangular frame shape, and can be moved up and down by being guided by the guide plate 45. The left and right end portions of the shielding plate 47 are held inside the frame portion 46. The frame portions 46 at the upper end portion and the lower end portion can close the gap 43A. A plurality of shielding plates 47 are provided so as to have a vertical width corresponding to the height above and below the vent 43A of the louver 41.

  A rack 48 is attached to the surfaces of the left and right frame portions 46 extending in the vertical direction. A pinion 49 attached in the vicinity of the guide plate 45 is engaged with the rack 48. A gear (not shown) is fixed to the rotation shaft of the pinion 49, and a worm gear (not shown) fixed to the rotation shaft of the motor 50 is engaged with the gear and is rotated by the rotation of the motor 50.

  The control circuit of the motor 50 is connected to the output terminal of the control device C described above. Based on the command signal from the control device C, the motor 50 is rotated in a predetermined direction at a predetermined number of rotations, and the frame portion 46 is moved in the vertical direction. It moves to open and close the vent 43A of the louver 41.

  The bathroom ventilator 1 is provided with an air pressure sensor (pressure sensor) (not shown) for detecting the air pressure inside the bathroom 9 as air pressure detecting means. The detection result of the air pressure sensor is inputted to the input / output terminal of the microprocessor of the control device C. In the microprocessor of the control device C, the permissible value for the air pressure detected by the air pressure sensor is set within a certain range, and the outdoor wind enters the duct 6 of the bathroom ventilator 1 and the exhaust air pressure in the duct 6 increases. When the air pressure detected by the air pressure sensor increases to a predetermined value or more, when the current for closing the gallery 41 is supplied from the microprocessor of the control device C to the relay of the motor 50, the motor 50 closes the gallery 41. Current flows, and the gap 43 </ b> A of the louver 41 is closed by the shielding plate 46. When the gap 43A of the garage 41 is closed, moist air inside the bathroom 9 is prevented from flowing into the dressing room through the gap 43A of the garage 41, and is prevented from condensing on the wall or ceiling of the dressing room. The

  When a large air volume exhaust device such as a range hood of a building is driven, air is sucked from the gallery 41, so that the air pressure inside the bathroom 9 decreases. When the air pressure detected by the air pressure sensor of the bathroom ventilator 1 is reduced to a predetermined value or less, when the current for closing the gallery 41 is supplied from the microprocessor of the control device C to the relay of the motor 50, the motor 50 is connected to the gallery 41. An electric current flows so as to close and the gap 43 </ b> A of the louver 41 is closed by the shielding plate 46. This prevents an increase in the load on the fan motors 27 and 32 of the air supply system fan 28 and the exhaust system fan 33.

  Instead of the air pressure sensor, an increase in air pressure may be detected by measuring the current of the fan motor 32 of the exhaust system fan 33. That is, when outside air enters the duct 6 due to strong wind or the like, the rotational speed of the exhaust fan 33 varies. The current of the fan motor 32 changes due to the fluctuation in the rotational speed of the exhaust fan 33. Therefore, the control device C is provided with a current sensor for monitoring the current supplied to the fan motor 32, and the detection result of the current sensor is compared with the allowable value provided in the microprocessor of the control device C, and the current exceeding the allowable value is determined.
