The air sucked from the air supply suction port 6 by the air supply and blow unit 3 passes through the suction side duct 10, the blowout side duct 9, and the elbow 11 and is blown to the blowout grill portion 8. Then, the blown air is blown out from the air supply outlet 15 of the blowout grill portion 8 to the bathroom 1.

  FIG. 3 is a block diagram showing the installed state of the blowout grille portion 8, and FIG. 4 is a cross-sectional view showing the AA cross section of FIG.

  The blowout grill portion 8 includes a grill base 12 and a decorative panel 13.

  The grill base 12 is installed on the ceiling of the bathroom 1 and fixed to the bathroom ceiling 2 from the bathroom 1 side, for example, with screws.

  The decorative panel 13 is attached to the grill base 12 from the bathroom 1 side, for example, with a screw (not shown). By providing the decorative panel 13, the designability seen from the bathroom 1 side in the installed state is improved.

  A reinforcing rib 29 is provided on a part of the long side of the grill base 12 to suppress deformation.

  As shown in FIG. 4, the grill base 12 is connected to the elbow 11 at the connection portion 14.

  The grill base 12 also has a charge inlet 23 and a charge outlet 15.

  The air supply inlet 23 is provided at a connection portion with the elbow 11 (a portion where the connection portion 14 and the elbow 11 are connected). That is, in the state where the grill base 12 and the elbow 11 are connected, the area surrounded by the connection portion 14 is the air supply inlet 23.

  The air supply outlet 15 is provided at a connection portion with the bathroom ceiling 2 (a portion where the bathroom ceiling 2 and the grill base 12 are in contact). Further, the shape of the air supply outlet 15 is, for example, rectangular.

  The air supply inlet 23 may be provided above the air supply outlet 15.

  Hereinafter, in the description, the air supply inlet 23 side is described as the upstream side (upper side), and the air supply outlet 15 side is described as the downstream side (lower side).

  From the difference in shape, the inside of the grill base 12 can be divided into a first space 16 and an opposite side from a third space 18 with the second space 17 including the supply air outlet 15 as a center. That is, the grill base 12 includes a first space 16, a second space 17, and a third space 18.

  The first space 16 includes a first curved portion 19.

  The first bending portion 19 curves so as to guide the wind toward the second space 17, particularly the air supply outlet 15.

  The second space 17 includes a charge air outlet 15 from which the air flowing in from the charge air inlet 23 is blown.

  The third space 18 includes a first wall 21 extending in a direction perpendicular to the air supply outlet 15.

  The first wall portion 21 is a wall surface perpendicular to the bathroom ceiling 2.

  The first space 16 faces the third space 18 via the second space 17.

  The charge inlet 23 is provided in the upper part of the first space 16, the second space 17 and the third space 18.

  According to such a configuration, the air sucked from the air supply suction port 6 by the air supply air blower 3 is supplied along the first curved portion 19 and the first wall portion 21 after passing through the air supply inlet 23. It is guided to the air outlet 15 and blown from the air supply outlet 15. The first curved portion 19 generates an oblique vector component in the direction of the air blown from the air supply outlet 15 and collides with the vertical vector wind along the first wall 21. Here, in the first curved portion 19 and the first wall portion 21, since the pressure loss is lower in the gently curved first curved portion 19, the wind speed becomes faster. Therefore, the wind of the vector in the vertical direction flowing along the first wall portion 21 is bent in the diagonal direction. That is, the direction of the air blown from the air supply outlet 15 is an oblique direction including the direction from the first space 16 to the third space 18 as a vector component. Thereby, the wind direction can be determined without using a structure such as a fin, that is, without complicating the structure. Moreover, the designability is improved by eliminating the need for structures such as fins. Furthermore, since the structure such as the fin is not required, the cleaning of the grill base 12 becomes easy.

The second bending portion 20 curves so as to guide the wind toward the second space 17, particularly the air supply outlet 15.

  The air flowing in from the air supply inlet 23 is blown to the air supply outlet 15 along the second curved portion 20 and the first wall portion 21. At this time, the pressure loss of the wind flowing through the third space 18 is reduced by the second curved portion 20, but since the second curved portion 20 is flatter than the first curved portion 19, the first curved portion The pressure loss is lower at 19 and the overall pressure loss can be reduced while obtaining the same effect in the wind direction.

  Further, as shown in FIG. 6, in the first space 16, a second wall extending in the vertical direction with respect to the air supply outlet 15 on the downstream side of the first curved portion 19 and the upstream side of the air supply outlet 15. 22 may be provided. At this time, the second wall portion 22 is provided at a position facing the first wall portion 21, and the end portion 30 on the air supply inlet side of the second wall portion is an end portion on the air supply inlet side of the first wall portion It is located downstream (downward) of 32. That is, the width in the vertical direction of the first wall 21 is larger than the width in the vertical direction of the second wall 22. According to such a configuration, since the vertical component of the wind blown out from the air supply outlet 15 is increased by blowing the air along the second wall portion 22, the wind can be blown further away.

  The second wall portion 22 may be inclined toward the second space 17, in particular, the air supply outlet 15. At this time, the second wall portion 22 guides the air blown along the first curved portion 19 diagonally toward the air supply outlet 15, so that the air can be more efficiently blown in the oblique direction. it can.

  Next, the instruction rib 31 will be described with reference to FIG. The blowout grill portion 8 shown in FIG. 8B is obtained by rotating the blowout grill portion 8 in the state of FIG. 8A by 180 degrees.

  As shown to Fig.8 (a), the 1st wall part 21 may have the instruction | indication rib 31 about height 2 mm which shows the blowing direction of the air ventilated from the air supply blower outlet 15, for example. At this time, the indication rib 31 is provided on the first wall portion 21 so that the indication rib 31 is positioned on the side to which the wind blown out is directed. Therefore, when the user touches the instruction rib 31 with the finger from the bathroom 1 side, the wind direction can be understood, and the wind direction confirmation after attachment becomes easy.

  The indication rib 31 may be provided in the vicinity of the air supply outlet 15. Thereby, since the indication rib 31 can be visually recognized from the bathroom 1 in the state in which the outlet grille part 8 is attached to the bathroom ceiling 2, the wind direction confirmation after attachment becomes easier.

  Next, the expansion space portion 24 will be described with reference to FIG. In addition, the blowing grill part 8 shown in FIG.9 (b) rotates 180 degree | times of the blowing grill part 8 of the state of Fig.9 (a).
