There is a problem that hot air leaks and a short circuit between the suction airflow and the blowout airflow occurs, and it is required to prevent the short circuit with a simple structure.

  Further, since the tightening amount of the screw 108 to which the front cover 107 is attached is not regulated, when the front cover 107 is formed of resin or thin, the front cover 107 is deformed when the tightening amount of the screw 108 is increased. Therefore, it is required to prevent the front cover from being deformed.

  The present invention solves such a conventional problem, and provides a bathroom heater / dryer capable of preventing a short circuit between an intake air flow and a blow-out air flow and preventing deformation of the surface of the grill. It is an object.

  In the present invention, a circulation part-side partition plate that partitions the suction opening and the blow-off opening in the circulation part and a grill-side partition plate that partitions the suction port and the outlet of the grill are provided to face each other.

  By this means, a bathroom heater / dryer capable of preventing a short circuit between the suction airflow and the blowout airflow can be obtained.

  Another means is provided with an abutting portion that abuts against the ceiling of the bathroom and regulates the tightening of the grill mounting screw.

  By this means, a bathroom heating dryer capable of preventing deformation of the grill surface is obtained.

  ADVANTAGE OF THE INVENTION According to this invention, the bathroom heating dryer which has the effect which can prevent the short circuit of a suction airflow and a blowing airflow can be provided.

  Moreover, the bathroom heating dryer which can prevent the deformation | transformation of the surface of a grill can be provided.

  According to the first aspect of the present invention, a grille having a suction opening and a blowout opening below, a circulation part having a circulation unit therein, and a suction opening and a blowout opening provided on the lower surface of the circulation part A circulation portion side partition plate that partitions the suction opening and the blowout opening in the circulation portion, and a grill side partition plate that partitions the suction port and the outlet of the grill in a shape along the circulation portion side partition plate, It is provided with the grill side partition plate facing the circulation part side partition plate, which can prevent short circuit of suction airflow and blowout airflow, even when the thickness of the ceiling of the bathroom where the bathroom heating dryer is installed is different The grill side partition plate can be made to correspond to the circulation part side partition plate.

  According to a second aspect of the present invention, when the grill mounting screw reaches a predetermined tightening amount in the vicinity of the grill mounting screw for mounting the grill, the grill mounting screw comes into contact with the ceiling of the bathroom. A contact part that regulates screw tightening is provided, and if the screw tightening amount of the screw for mounting the grill is too large, the grille will be deformed in a concave shape, but before the grille is deformed, the contact part Is in contact with the ceiling surface of the bathroom and tightening of the screws for mounting the grill is restricted, and deformation of the grill can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1 to FIG. 4, a circulation motor 1, a circulation fan 2, a circulation component 3, and a heat exchanger 4 that heats using hot water heat are integrally formed. The circulation unit 5 is assembled in the outer case 6 and provided with a circulation part 9 in which a suction opening 7 and a blow-off opening 8 are formed in the lower part. The grill 11 provided below the circulation portion 9 is provided with a grill-side partition plate 14 that partitions the suction port 12 and the outlet 13 of the grill 11 in a shape along the circulation portion-side partition plate 10. 10 is formed so that the grill-side partition plate 14 faces the plate.

  In addition, the grill 11 is abutted against the ceiling 16 of the bathroom and tightens the grill mounting screw 15 when the grill mounting screw 15 reaches a predetermined tightening amount in the vicinity of the grill mounting screw 15. A restricting contact portion 17 is provided and configured.
