Thereby, the distance from each edge part of the suction inlet 32 to the front panel 21 and the back panel 22 becomes small with respect to the longitudinal direction dimension 32X of the suction inlet 32.

  Next, the configuration of the air supply device 34 will be described with reference to FIGS. 3 and 4 are schematic cross-sectional views showing the vicinity of the outlet of the bathroom dryer according to the first embodiment of the present invention. FIG. 5 is a diagram for explaining the configuration of the air supply device in the bathroom dryer according to the first embodiment of the present invention. Specifically, FIG. 3 is a schematic diagram illustrating a state in which air is blown out to the bathroom space 20 and the ceiling panel 26, and FIG. 4 is a schematic diagram illustrating a state in which air is blown out to the bathroom space 20.

  As illustrated in FIG. 3, the air supply device 34 includes a casing 36, a pipe 43, and a guide 300.

  The casing 36 is a metal box serving as a casing of the air supply device 34, and the outer shape thereof has a substantially rectangular parallelepiped shape whose longitudinal direction is the depth direction (the arrow X direction in FIG. 1). Inside the casing 36, a pipe 43 and a fan 41 (see FIG. 5) are arranged.

  The fan 41 is an electric blower that operates by receiving power supply, and here, a centrifugal fan is employed. A sirocco fan (not shown) of the fan 41 rotates about an axis extending in the vertical direction. As a result, air is sucked from the suction port 41a that opens upward, and blown out toward the back panel 22 in the depth direction of the pipe 43 through an internal flow path (not shown).

  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, a louver 462 is provided inside the pipe 43 so as to be rotatable together with the rotational drive of the motor 500 (see FIG. 5).

  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 that has been taken into the casing 36 and has flowed through the first internal flow path 401 toward the front panel 21 in the depth direction is blown out by the fan 41, and is turned back to the second internal flow path 402. In the direction toward the back panel 22 side.

  The pipe 43 has a notch 43c in a part below. Further, a louver 462 having a circular cross section is provided inside the pipe 43 so as to cover the notch 43c. The louver 462 has a hole 35bb, a hole 35aa, and a hole 35bb formed in a part of the louver 462 at positions spaced apart from each other in the depth direction (arrow X direction). The hole 35bb has an opening shape larger than the hole 35aa. The second internal flow path 402 inside the pipe 43 communicates with the bathroom space 20 via the first air outlet 35a constituted by the hole 35aa and the second air outlet 35b constituted by the hole 35bb. As described above, since the hole 35bb has a larger opening shape than the hole 35aa, the flow rate of air blown from the second blower outlet 35b is larger than the flow rate of air blown from the first blower outlet 35a. The flow rate is larger.

  As shown in FIG. 4, the louver 462 is configured to be rotatable within a range represented by an arrow R along the inner surface of the pipe 43 around the central axis C of the pipe 43. By the rotation of the louver 462, the direction in which the first air outlet 35a and the second air outlet 35b blow out air changes within a predetermined range.

  The guide 300 is a member for guiding the direction of air blown out from the air outlet 35 along the ceiling panel 26. The guide 300 is a hollow member that covers a part of the louver 462 and is arranged along the ceiling panel 26. The guide 300 has an open end 300a on the louver 462 side and an end 300b on the ceiling panel 26 side. Thereby, when the louver 462 rotates along the inner surface of the pipe 43, the air blown from the first air outlet 35a or the second air outlet 35b opened in the louver 462 is caused to flow into the guide 300, Air can be blown out from the end portion 300 b of the guide 300 along the ceiling panel 26.

  More specifically, the air blown out from the air outlet 35 is guided by the guide 300 as follows. For example, as shown in FIG. 3, when the louver 462 rotates, that is, the louver 462 rotates so that the second air outlet 35b communicates with the bathroom space 20, and the first air outlet 35a communicates with the inside of the guide 300. When moved, the air blown from the second outlet 35b is directed into the bathroom space 20 as indicated by the arrow F12, and the air blown from the first outlet 35a is within the guide 300 as indicated by the arrow F11. Head to. The air from the first air outlet 35a toward the guide 300 passes through the guide 300 and is blown out from the end 300b along the ceiling panel 26. The air blown out along the ceiling panel 26 proceeds in a state along the ceiling panel 26 and then is sucked into the suction port 32 (see FIG. 1) as it is. As described above, the guide 300 is configured so that the air blown from the first blower outlet 35a is directed along the ceiling panel 26 so as to go directly to the suction port 32 without circulating through the bathroom space 20. The direction of the air blown out from the outlet 35a is guided.

  In addition, in FIG. 3, although the guide 300 has shown the state which guides the direction of the air blown off from the 1st blower outlet 35a, the guide 300 guides the direction of the air blown off from the 2nd blower outlet 35b. You may comprise as follows. In this case, the guide 300 is directed to the direction of the air blown out from the second air outlet 35b so that the air blown out from the second air outlet 35b is directed to the suction port 32 as it is along the ceiling panel 26. To guide you. Further, the shape and size of the guide 300 can be selected as appropriate.

  For example, as shown in FIG. 4, when the louver 462 rotates, that is, the first air outlet 35 a communicates with the bathroom space 20, while the second air outlet 35 b communicates with both the bathroom space 20 and the guide 300. When the louver 462 rotates so as not to communicate, air is blown out only from the first air outlet 35a to the bathroom space 20. The air blown into the bathroom space 20 circulates through the entire bathroom space 20 and is then sucked into the suction port 32.

  According to the bathroom dryer according to the first embodiment of the present invention configured as described above, the air blown from the first air outlet 35a is directed toward the air inlet 32 in a state along the ceiling panel 26. In addition, air is blown out from the first air outlet 35a. Thereby, the air blown out from the first air outlet 35 a can be sucked into the air inlet 32 without being circulated through the bathroom space 20 and along the ceiling panel 26. For this reason, the air blown out from the first air outlet 35a circulates through the bathroom space 20 and then is sucked into the air inlet 32, thereby preventing air containing a lot of moisture from accumulating on the ceiling panel 26 of the bathroom space 20. be able to. As a result, it is possible to prevent condensation on the ceiling panel 26 of the bathroom space 20.

  Moreover, since the guide 300 which guides the direction of the air which blows off from the 1st blower outlet 35a is provided, the air blown off from the 1st blower outlet 35a followed the ceiling panel 26 without circulating the inside of the bathroom space 20. In the state, it can guide easily in the direction which goes to the suction inlet 32, and the ceiling panel 26 can be dried more efficiently.

  In addition, the distance 35X1 from the end of the blower outlet 35 to the front panel 21 and the distance 35X2 from the end of the blower outlet 35 to the back panel 22 are both made smaller than the longitudinal dimension 35X of the blower outlet 35. The air blown out from the air outlet 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 ceiling panel 26 and dried.

  Further, 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 back panel 22 are both smaller than the longitudinal dimension 32X of the suction port 32. The air in the bathroom space 20 sucked in through 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, so that the air current is spread over a wide area of the bathroom space 20 and dried. It becomes possible to make it.

  Also, the direction in which the plurality of holes 32a of the suction port 32 are arranged, the longitudinal direction of the suction port 32, and the direction in which the plurality of holes 35aa and 35bb of the outlet 35 are arranged, and the longitudinal direction of the outlet 35 Are made substantially parallel to each other, so that a wide curtain-shaped airflow formed by blowing air from the air outlet 35 can be brought to the suction port 32 without breaking the shape of the airflow. The panel 26 can be spread over a wide area and dried.

  In addition to the above embodiment, a heating means (not shown) such as a heater is installed on the downstream side of the fan 41 to warm the blown air and reduce the relative humidity, thereby preventing the condensation on the ceiling panel 26. It can be further increased.

  Furthermore, it is also possible to exhaust a part of the sucked air out of the bathroom so that the air outside the bathroom can be actively taken into the bathroom through an opening provided in the bathroom door or the like. . When the humidity in the bathroom is very high, such as immediately after bathing, the humidity in the bathroom can be quickly lowered by taking in the low humidity outside the bathroom into the bathroom, and the effect of preventing condensation on the ceiling panel 26 can be expected.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples. In other words, those specific examples that have been appropriately modified by those skilled in the art are also included in the scope of the present invention as long as they have the characteristics of the present invention.
