It is attached to the lower surface of the left-right outer edge part of the said base plate, It has a decorative board which coat | covers the back of the left-right side surface of the said toilet bowl main body.

  In this toilet apparatus, since the intake port is formed in the overhanging portion, the upper surface of the toilet body does not exist near the lower portion of the intake port, and a wide space can be provided below the intake port. For this reason, the air inlet has a small inflow resistance of air and can suck air from a wide space extending downward. That is, as the fan is driven, the functional device can suck sufficient air from the intake port.

  Therefore, the toilet device of this invention can operate a functional apparatus favorably.

The functional device has a filter covering the air inlet, said base plate, Ru Tei guide portion is provided for guiding the filter inserted from the outer edge to a position covering the air inlet. In this case, since the guide portion is provided on the base plate, the filter can be reliably guided and arranged at an appropriate position with respect to the air inlet provided on the base plate. Further, since the intake port is opened downward, air is sucked when the fan is driven, and dust or the like adhering to the lower surface of the filter falls downward when the fan stops driving. For this reason, it is difficult for the filter to be clogged with dust or the like, and the functional device can suck air well, so that the functional device can be operated well.

The base plate is provided at an outer edge portion, and has an insertion port into which the filter is inserted.

Further, the intake port can be disposed at a position overlapping the exhaust path in the front-rear direction. For this reason, the arrangement area with respect to the base plate of a functional apparatus can be made small.

The base plate has a wall erected along the periphery of the intake port, by said casing of the wall portion and the functional device is connected, the intake passage can be formed. In this case, the cross-sectional area of the intake passage can be increased as compared with the case where the intake passage is formed only by the casing or the wall portion. In other words, when the intake passage is formed only by the casing or the wall portion, it must have a draft due to the restriction of the forming means, and the sectional area of the intake passage must be gradually reduced. On the other hand, since the intake passage is formed by the wall portion and the casing, the cross-sectional area of the intake passage can be increased without being affected by the draft angle.

Another toilet device of the present invention is a toilet device provided with a base plate in which a functional device with a built-in fan is fixed in a casing and can be placed on the upper surface of the toilet body.

  The rear base plate 41 has an intake port 47 formed in a horizontally elongated shape along the rear side of the front wall portion 43F formed continuously with the right wall portion 43S. The intake port 47 is formed in the overhanging portion 41H. The upper surface 2T of the toilet body 2 does not exist below the intake port 47, and the intake port 47 opens toward a wide space extending below the intake port 47. For this reason, the air inlet 47 has low inflow resistance of air and can suck air from a wide space extending downward. That is, the room heating device 50 can suck sufficient air from the air inlet 47 in accordance with driving of the fan 53 described later.

  Therefore, the flush toilet of the embodiment can operate the room heating device 50 satisfactorily.

  As shown in FIGS. 3 to 6, the room heating device 50 includes a fan 53 in a casing 52. The fan 53 is a disk-shaped sirocco fan that sucks air from the side surface 53A orthogonal to the rotation axis and discharges the air outward from the circumferential surface by centrifugal force.

  The casing 52 of the room heating device 50 is formed of a first member 54, a second member 55, and a third member 56. The first member 54 and the second member 55 are formed in a substantially target shape. The end portions of the side surface portion 54S of the first member 54 and the side surface portion 55S of the second member 55 are joined together. The first member 54 and the second member 55 form a substantially cylindrical space in which the fan 53 is housed. The first member 54 and the second member 55 communicate with the lower part of the substantially cylindrical space formed in the upper part, and form an exhaust passage 57 extending obliquely downward. Lower portions of the first member 54 and the second member 55 that form the exhaust path 57 are inserted through openings that are provided in the rear base plate 41 so as to penetrate vertically, and extend below the rear base plate 41. A hot air outlet 51 is formed at the downstream end of the exhaust passage 57. The warm air outlet 51 is disposed at a position facing the slit hole 31 of the decorative plate 30 attached to the lower surface of the right outer edge portion of the rear base plate 41. The warm air outlet 51 is provided with a louver 51L that guides the blowing direction of the warm air diagonally downward. The first member 54 forms the substantially cylindrical space in which the fan 53 is accommodated, the exhaust passage 57, the warm air outlet 51 and the louver 51L, and the second member 55 forms the front. The first member 54 and the second member 55 are provided with a heat generating portion 58 at the upper part on the downstream side of the exhaust passage 57. The heat generating portion 58 has a heat generating body 58F disposed so as to face the exhaust path 57.

  The second member 55 is provided with an opening 55 </ b> A at a portion facing a side surface 53 </ b> A orthogonal to the rotation axis of the fan 53 when the fan 53 is housed. A part of the side surface portion 56S is attached to the third member 56 along the upper portion of the edge portion of the opening 55A. The front surface portion 56F that is continuous with the side surface portion 56S of the third member 56 is disposed at a position spaced apart from the second member 55. An inflow port 59 that opens downward is formed by the lower end of the third member 56.

  A lower portion of the casing 52 in which the fan 53 is housed is fitted between a front wall portion 43F, a rear wall portion 43B, and a right wall portion 43S provided on the rear base plate 41. In this state, the lower end of the third member 56 of the casing 52 is connected to the upper end of the front wall portion 43F. Thus, an intake passage 48 is formed by the front wall portion 43F, the third member 56 of the casing 52, and the second member 55. Since the intake passage 48 is thus formed, the cross-sectional area of the intake passage 48 can be increased. The lower end (upstream end) of the intake passage 48 communicates with the intake port 47 formed in the projecting portion 41H of the rear base plate 41 from above.

  The filter F includes a flat frame portion 100 having a plurality of divided net portions 101 and a grip portion 102 that is provided at one end of the frame portion 100 and rises upward. The filter F is provided with an inclined piece 102 </ b> A that extends from the upper end of the grip portion 102 and is connected to the upper surface of the frame portion 100. A recess 102S that opens to the front side is formed between the grip portion 102 and the inclined piece 102A. A guide piece 104 projects from the front side surface of the frame portion 100 on the gripping portion 102 side (the side surface located on the front side when the filter F is mounted so as to cover the intake port 47). Further, an elastic piece 103 formed by a notch groove provided in a U-shape is provided on the upper surface of the frame portion 100 on the gripping portion 102 side. A convex portion 103 </ b> A is provided on the top end surface of the elastic piece 103. On the upper surface in the second insertion port 45 formed in the rear base plate 41, there is provided a recess 45B that engages with the protrusion 103A when the filter F is inserted into an appropriate position.

  As shown in FIGS. 7 to 10, the frame portion 100 of the filter F has a first inclined side surface 100 </ b> A that is inclined rearward in the front end direction at the front end portion of the front side surface. Further, the frame portion 100 of the filter F has a second inclined side surface 100B that is inclined rearward in the front end direction at an intermediate portion of the rear side surface. A side surface of the guide piece 104 on the insertion tip side is formed with a third inclined surface 104A that approaches the front side surface of the frame portion 100 in the insertion direction.

  The rear base plate 41 forms a front side wall of the second insertion port 45, and has ribs 49 that protrude from the upper surface so as to surround three sides of the air intake port 47. The rib 49 is continuous with the front rib 49A positioned in front of the air inlet 47, the rear end of the front rib 49A, the rear rib 49B positioned in the rear with respect to the air inlet 47, and the rear rib 49B. It is composed of a rear rib 49 </ b> C that is continuous with the side end portion and is located behind the air inlet 47. The intake port 47 is provided inside the first insertion port 44 and the second insertion port 45 which is shifted rearward. The first rib 49A is provided with a first inclined surface 49P and a second inclined surface 49Q that are provided to be inclined rearward in the depth direction. The rear rib 49C is formed with a third inclined surface 49R provided to be inclined rearward in the back direction.

  The front rib 49 </ b> A is a guide portion that guides the filter F inserted from the first insertion port 44 and the second insertion port 45 to a position that covers the intake port 47. That is, as shown in FIG. 8, when the filter F is inserted from the first insertion port 44 and the second insertion port 45, first, the first inclined side surface 100A of the filter F collides with the first inclined surface 49P of the front rib 49A. As a result, the filter F slides obliquely backward intersecting the insertion direction. When the filter F is further moved in the insertion direction, as shown in FIG. 9, the side corner portion 100C of the filter F collides with the second inclined surface 49Q. Thereby, the filter F slides further diagonally backward which cross | intersects an insertion direction. When the filter F is further moved in the insertion direction, the third inclined side surface 104 </ b> A of the guide piece 104 collides with the front rib 49 </ b> A that forms the second insertion port 45. Thereby, the filter F slides further back diagonally intersecting the insertion direction. Thereafter, as shown in FIG. 10, the filter F is inserted into an appropriate position covering the intake port 47. In this state, the protrusion 103A provided on the elastic piece 103 is engaged with the recess 45B.

  In this way, the filter F is reliably guided and arranged at an appropriate position with respect to the air inlet 47 provided in the rear base plate 41 by the front rib 49A provided in the rear base plate 41. Further, since the filter F can be directly attached to the intake port 47, a gap between the filter F and the intake port 47 can be eliminated, and entry of dust and the like into the intake passage 48 can be reduced. Further, the exhaust passage 57 and the intake port 47 can be disposed at positions where they overlap in the front-rear direction. For this reason, the arrangement area with respect to the rear base plate 41 of the room heating apparatus 50 can be reduced.

  When the filter F is inserted at an appropriate position, the grip portion 102 of the filter F is substantially flush with the outer surface of the right wall portion 43S. For this reason, the cover 10 can be smoothly raised and lowered along the right wall portion 43 </ b> S, and the grip portion 102 can be concealed by the side surface portion 10 </ b> A of the cover 10. For this reason, the toilet apparatus 1 can be made into the clean shape which does not have an unevenness | corrugation in a side part, and can improve appearance. Further, when the cover 10 is raised, the grip portion 102 of the filter F is exposed, so that the grip portion 102 can be gripped by inserting a fingertip into the recess 102S. For this reason, the filter F can be easily removed.

  When removing the filter F, the rear rib 49C serves as a guide portion for guiding the filter F. That is, as shown in FIG. 9, when the filter F is pulled out, the second inclined side surface 100B of the filter F collides with the third inclined surface 49R of the rear rib 49C. Thereby, the filter F slides diagonally forward that intersects the pulling direction. When the filter F is further pulled out, the second inclined side surface 100 </ b> B of the filter F collides with the rear side wall that forms the second insertion port 45. Thereby, the filter F slides diagonally forward intersecting the extraction direction, and the filter F can be extracted from the second insertion port 45 and the first insertion port 44.
