When power is supplied to the fan 41, a motor (not shown) is driven to rotate, and a sirocco fan (not shown) fixed to the output shaft rotates about an axis extending in the vertical direction. Thereby, air is sucked from the suction port 41a that opens upward, and blown out toward the right side panel 24 in the left-right direction.

  The pipe 43 is a metallic tubular member disposed adjacent to the fan 41 in the depth direction (arrow X direction). The pipe 43 has an end 43b on the side opposite to the fan 41 closed, while an end 43a on the fan 41 side is open. As a result, the air blown out by the fan 41 flows into the pipe 43 from the end 43a. As will be described later, an air volume restricting louver 561 (not shown in FIG. 2) is rotatably provided inside the pipe 43.

  Inside the casing 36, the pipe 43 is arranged, so that the first internal flow path 401 outside the pipe 43 and the flow path downstream of the first internal flow path 401 and the second inside the pipe 43. It is partitioned into an internal flow path 402. That is, the air taken into the casing 36 from the communication port 37 and flowing in the first internal flow path 401 in the left-right direction toward the left side panel 23 is blown out by the fan 41 and folded so as to be folded back. It will flow through the flow path 402 in the left-right direction toward the right side panel 24 side.

  All of the heaters 44a, 44b, and 44c are disposed in the vicinity of the outlet 35 of the second internal flow path 402, and generate heat when supplied with electric power. The heaters 44a, 44b, and 44c are arranged at intervals from each other along the longitudinal direction (depth direction) of the air outlet 35.

  Next, with reference to FIG. 3 thru | or FIG. 4, arrangement | positioning of the suction inlet 32 and the blower outlet 35, and the airflow formed in the bathroom space 20 by them are demonstrated. FIG. 3 is a schematic plan view showing a unit bath with a bathroom dryer according to the first embodiment of the present invention. FIG. 4 is a schematic cross-sectional view showing the vicinity of the air outlet of the bathroom dryer provided in the unit bath with the bathroom dryer according to the first embodiment of the present invention. Specifically, FIG. 3 is a schematic diagram showing a positional relationship between the unit bath 2, the suction port 32 and the blower port 35, and FIG. 4 is a depth direction of the pipe 53 provided in the longitudinal direction of the intake device 31. It is sectional drawing in the plane perpendicular | vertical to.

  As shown in FIG. 3, in the left-right direction (arrow Y direction), regions from the end 26L (left side panel 23 side) to the end 26R (right side panel 24 side) of the ceiling panel 26 are defined as regions Y1 and Y2. , Y3 is divided into three equal parts, the air outlet 35 is provided in the region Y1, and the suction port 32 is provided in the region Y3. In other words, assuming that the horizontal dimension of the ceiling panel 26 is Ly, the air outlet 35 is provided within a range Ly / 3 from the end 26L, and the suction port 32 is within a range Ly / 3 from the end 26R. Is provided.

  In the depth direction (arrow X direction) that is the longitudinal direction of the air outlet 35, the distance 35X1 from the end of the air outlet 35 to the front panel 21 and the distance 35X2 from the end of the air outlet 35 to the back panel 22 are Is smaller than the longitudinal dimension 35X of the air outlet 35.

  Further, in the depth direction (arrow X direction) which is the longitudinal direction of the suction port 32, the distance 32X1 from the end of the suction port 32 to the front panel 21 and the distance 32X2 from the end of the suction port 32 to the rear panel 22 are , Both are smaller than the longitudinal dimension 32X of the inlet 32. A part of the suction port 32 is closed by an air volume restricting louver 561 described later. In the example of FIG. 3, the central portion of the suction port 32 is closed. Therefore, the air in the central portion of the suction port 32 is also sucked from both ends. As a result, the air volume at both ends of the air inlet 32 is increased, and the air volume at the corner of the bathroom that is difficult to dry can be increased.

  Inside the intake device 31, a pipe 53 is provided in the longitudinal direction. As shown in FIG. 4, the pipe 53 has a plurality of holes 32 a below it. Further, an air volume restricting louver 561 having a circular cross section is provided inside the pipe 53 so as to cover the plurality of holes 32a. The air volume restricting louver 561 can block a part of the suction port 32. Further, the air volume restricting louver 561 is provided with an opening in the longitudinal direction, and communicates with the bathroom space 20 through the suction port 32.

  When the air blown out by the fan 41 (see FIG. 2) passes in the vicinity of the heaters 44a, 44b, and 44c (see FIG. 2), heat is generated from the heaters 44a, 44b, and 44c that generate heat and become high temperature. Is heated to a high temperature. For this reason, the air is blown out into the bathroom space 20 at a high temperature immediately after being heated by the heaters 44a, 44b, 44c. The air blown into the bathroom space 20 is sucked upward from below through the suction port 32 provided in the louver 561.

  The air volume restricting louver 561 is configured to be rotatable within a range indicated by an arrow R along the inner surface of the pipe 53 around the central axis C of the pipe 53. It is desirable that the air volume restricting louver 561 be composed of a rotating member driven by a motor or the like. The location where the suction port 32 is blocked can be changed by the rotation of the air volume restricting louver 561.

  FIG. 5 is a diagram schematically showing an example of the air volume restricting louver 561. FIG. 5A shows a gradually varying type air volume restricting louver 561, and FIG. 5B shows a discrete type air volume restricting louver 561. FIG. In addition, the widths in the short direction of the regions (a), (b), and (c) shown in FIGS. 5 (A) and 5 (B) are preferably not more than the width of the suction port 32 in the short direction. . In FIG. 5, as an example, the width in the short direction of the regions (a), (b), and (c) is assumed to be smaller than the width of the suction port 32 in the short direction. Thereby, since the blocking means does not protrude from the suction port 32, the design can be ensured.

  FIG. 5A shows a gradually changing type air volume restricting louver 561. In the gradual change type, as shown in FIG. 5A, the opening A1 located at the center of the air flow restricting louver 561 is opened so as to be parallel to the central axis C of the pipe of the air flow restricting louver 561. Has been. Furthermore, the openings A2 and A3 located on the end side are provided so as to be inclined with respect to the central axis C. As a result, the region (a) in FIG. 5A includes at least a part of the openings A2 and A3 on the end side, and does not include the opening A1 in the center. In addition, the region (b) in FIG. 5A includes at least a part of the central opening A1, and does not include the openings A2 and A3. Further, the region (c) in FIG. 5A does not include an opening.

  FIG. 5B shows a discrete type air volume restriction louver 561. In the example of FIG. 5B, the opening B1 provided at the center of the air volume restricting louver 561 and the openings B2 and B3 provided at the ends have the same area. Further, the openings B1, B2, and B3 are all provided in parallel to the central axis C. Further, the openings B2 and B3 are provided so that the bottoms thereof coincide with the middle line of the opening B1 parallel to the central axis C. As a result, the region (a) in FIG. 5B includes at least part of the openings B2 and B3 on the end side, and does not include the opening B1 in the center. In addition, the region (b) in FIG. 5B includes at least a part of the central opening B1, and does not include the openings B2 and B3. Further, the region (c) in FIG. 5B does not include an opening. Note that the air volume restricting louver 561 shown in FIG. 5 is an example, and the size and angle of the opening are not limited thereto.

  As described above, the air volume restricting louver 561 partially closes the suction port 32, whereby the amount of air blown out from the suction port can be partially increased. The amount of can be increased.

  According to the unit bath with a bathroom dryer according to the first embodiment of the present invention configured as described above, first, among the regions of the ceiling panel 26 viewed in three equal parts in the left-right direction (arrow Y direction) The air outlet 35 is provided in the region Y1, and the suction port 32 is provided in the region Y3 farthest from the region Y1, so that the air outlet 35 and the suction port 32 are greatly separated in the depth direction. Thereby, the expression of the short circuit phenomenon which the airflow formed with the air which blows off from the blower outlet 35 advances toward the suction inlet 32, without reaching the floor panel 25 etc. of the unit bath 2 can be suppressed. .

  In addition, although it is supposed here that the blower outlet 35 and the suction inlet 32 are provided in the area | region of both ends among the area | regions of the ceiling panel 26 seen by dividing into 3 parts, the expression of a short circuit phenomenon is suppressed more reliably. Therefore, it is more preferable to provide the ceiling panel 26 in the regions at both ends when the region of the ceiling panel 26 is divided into four equal parts.

  Further, the distance 35Y1 from the end of the air outlet 35 to the left side panel 23 and the distance 35Y2 from the end of the air outlet 35 to the right side panel 24 are both smaller than the longitudinal dimension 35Y of the air outlet 35. Thus, the air blown out from the air outlet 35 forms a wide curtain-like air flow while entraining the air in the vicinity of the front panel 21 and the back panel 22. As a result, the airflow can be spread over a wide area of the bathroom space 20 and dried.

  Further, the distance 32X1 from the end of the suction port 32 to the left side panel 23 and the distance 32X2 from the end of the suction port 32 to the right side panel 24 are both smaller than the longitudinal dimension 32X of the suction port 32. Thus, the air in the bathroom space 20 sucked in by the suction port 32 forms a wide curtain-like air current while entraining the air in the vicinity of the front panel 21 and the rear panel 22, and thus the air current is spread over a wide area of the bathroom space 20. It becomes possible to dry.

  In addition, since the air volume restricting louver 561 that closes a part of the suction port 32 is provided, the air volume of the portion of the bathroom that is difficult to dry can be increased. As a result, for example, the occurrence of mold can be suppressed even in places where air stays in the corners of the bathroom and is difficult to dry.

  Further, since the air volume restricting louver 561 is constituted by a rotating member or the like driven by a motor or the like, it does not protrude from the suction port 32 and is excellent in design.
