The outside air can be circulated and the mold prevention effect is obtained.
Moreover, since the ventilation louver provided under the normal door is not necessary, the gap air from the louver can be eliminated, and the cold is not felt at the washing place in winter.

Moreover, the said bathroom ventilator can also be set as the structure which the said blower outlet has faced the direction of the wall near a door so that the external air blown out indoors may flow along the wall which comprises the inner periphery of a bathroom.
In this way, outside air can be blown from the air outlet to the bathroom wall near the door, allowing the outside air to flow along the wall to the inner periphery of the bathroom, and in particular, eliminating mold generated on the bathroom wall on the door side. Will be able to.

Further, in the bathroom ventilation apparatus, a configuration may be adopted in which a blowing portion is provided at least on the bottom surface of the door so that a part of the outside air sent from the fan is blown out also from the peripheral surface of the door. it can.
If it carries out like this, external air will be blown out from the blowing part of the bottom face of a door, and the mold | generation which generate | occur | produces in the sash frame etc. of the outer periphery of a door can be prevented favorably.

Next, the best mode for carrying out the present invention will be described using examples.
FIG. 1 is a plan view of a bathroom. Walls 4a, 4b, 4c, and 4d are erected on the outer periphery of the bathroom washroom 2 and bathtub 3, and a door 5 is openable and closable on the wall 4d side. Is provided. Further, an exhaust fan K for exhaust is provided on the ceiling above the bathtub 3.
The door 5 is formed of a folding door in FIG. 1, and the main folding door 51 and the sub folding door 52 are connected by a connecting shaft 53, and the sub folding door 52 can be folded on the main folding door 51 in an overlapping manner. This door 5 is provided so that it can be opened and closed to the wall 4a side through a hinge portion 6 formed of a hinge.

FIG. 2 shows a front view of the door 5 as seen from the washing room 2 side, and FIG. 3 shows a cross-sectional view taken along line AA in FIG.
On the hinge part 6 side of the main folding door 51 that constitutes the door 5, a plurality of air outlets 9 are formed in substantially the entire vertical direction of the main folding door 51 at intervals in the vertical direction.
As shown in FIG. 3, the main folding door 51 has a structure in which a wind tunnel S is formed in the vertical direction between the indoor wall portion 51a constituting the surface on the washing room 2 side and the outdoor wall portion 51b on the dressing room side. A plurality of outlets 9, 9, 9 are opened in the vertical direction on the indoor wall 51a side. Further, a slit for draining is formed on the lower end side of the main folding door 51, and it is configured so that air can be blown downward also from the slit 10 for draining water.

  A sirocco fan 7 is provided at the upper end of the wind tunnel S of the main folding door 51, and an intake port 8 for sucking outside air is opened on the outdoor wall 51 b side of the sirocco fan 7. The sirocco fan 7 has a diameter of, for example, about 100 mm, and is configured by a small sirocco fan having a thickness of about 20 to 30 mm.

  For example, as shown in FIG. 4, which is a cross-sectional view taken along line B-B of FIG. 2, the plurality of air outlets 9 have extended passages 91 extending from the wind tunnel S in the main folding door 51 toward the indoor wall portion 51 a. Formed, bent 90 ° at the tip of the extension passage 91 to form a bent passage 92, and bent at 90 ° in parallel to the extension passage 91 at the tip of the bent passage 92 to form an outlet passage 93. The air outlet 9 is formed on the side of the indoor wall 51a of the outlet passage 93, and the passage connecting the outlet 9 and the wind tunnel S is formed as a curved passage. Water intrusion into the inside can be satisfactorily prevented.

  In such a structure, when the sirocco fan 7 is rotated, outside air is sucked into the wind tunnel S from the air inlet 8, and the outside air passes through the passages 91, 92, and 93 from the wind tunnel S into the bathroom 1. The outside air is blown out vertically from a plurality of outlets 9 formed in the vertical direction, flows along the walls 4a and 4b as shown in FIG. 1, and is provided on the ceiling above the bathtub 3. It is made to flow toward the ventilation fan K. In addition, since the wind flows over the entire area of the walls 4a and 4b in the vertical direction, mold that tends to occur on the inner periphery of the walls 4a and 4b can be prevented well.

  Further, as shown in FIG. 5, the door lower frame 11 is provided on the frame receiving portion 21 a of the waterproof pan 21 constituting the washing place 2, and the main folding door 51 constituting the door stands on the door lower frame 11. In the structure provided, a packing 12 and a packing 13 are provided to seal between the floor surface 14 on the dressing room side, the door lower frame 11, and the main folding door 51. Water droplets are easily attached from the side, and mold is likely to be generated at this portion, but outside air that passes through the wind tunnel S is also blown out from the blowing portion 10 that also serves as a draining slit opened at the bottom surface of the main folding door 51. Therefore, generation of mold around the door lower frame 11 can be satisfactorily prevented.

In addition, even in the structure as shown in FIG. 6 where the packings 12 and 13 are not present, it is possible to favorably prevent the occurrence of mold by applying external air to the door lower frame 11 from the blowing portion 10.
In FIG. 6, an upright portion 21b is integrally formed in a rising shape on the outer periphery of the waterproof pan 21, and a frame receiving portion 21a is formed substantially horizontally at the upper end of the upstanding portion 21b. This is a type in which the door lower frame 11 is installed.

In addition, in this example, although what formed the blowing part 10 in the lower end bottom face of the main folding door 51 is illustrated, it blows out similarly to peripheral surfaces, such as the top | upper surface part of the main folding door 51, and the left and right side parts. If the part is left open, mold generated on the top frame and the left and right side frames of the door 5 can be well prevented.
In addition, in this example, although the thing which opened the some blower outlet 9,9,9 in the up-down direction is illustrated, this several blower outlet 9 may be a vertically long thing, and is a vertically long slit. It can also be comprised by the 1 or several blower outlet 9 long in the up-down direction.

  In this way, the outside air is blown out from the air outlet 9 into the bathroom 1 in the vertical direction, and the door 5 does not need to be provided with a louver on the lower end side as in the prior art. When performing hair washing or the like, there is a case where a gap wind enters from the bottom side of the louver and feels cold, but in this example, the gap wind does not enter the washing place 2.

FIG. 7 is a schematic plan view showing a modification.
In FIG. 7, the door 5 is formed of a single face material 55, and the face material 55 is inclined obliquely toward the wall 4 a in the vicinity of the door 5, and a plurality of outlets in the vertical direction. 9 is formed. A duct member 16 having a U-shaped cross section is attached to the dressing chamber side of the face material 55 at the position of the air outlet 9, and a vertical wind tunnel S is formed between the duct member 16 and the face material 55. The sirocco fan 7 can be provided on the upper end side of the wind tunnel S. When the sirocco fan is rotated, the sirocco fan 7 passes through the wind tunnel S in the duct member 16 and extends from the plurality of vertical outlets 9 toward the wall 4a. Thus, the outside air is blown out, and the outside air can flow well along the wall 4a in the entire vertical direction.

In particular, when the door 5 is opened to the washing place 2 side, the door 5 is almost in contact with the wall 4a side and mold is likely to be generated on the wall 4a. Therefore, the generation of mold near the door 5 of the wall 4a can be surely prevented.
In FIG. 7, the door 5 is provided with a frame member on the outer periphery of the face material 55 in a frame shape. In FIG. 7, a right vertical frame 56 a and a left vertical frame 56 b are illustrated, and the left and right vertical frames 56 a and 56 b are illustrated. Door frames 15a and 15b are erected on the outside.

  In addition, what is shown in the plane sectional view of FIG. 8 is the upper end in the vertical fence 56 using the vertical fence 56 provided in the vertical direction on the outer periphery of the face material 55 of the door 5 erected vertically. A sirocco fan 7 is provided on the side, and a vertical wind tunnel S is formed in the vertical gutter 56, and the air inlet 8 is connected to the sirocco fan 7 in the dressing room side of the gutter 56. Opened in the corresponding position. In addition, a blower outlet 9 is formed in the bathroom 1 side of the vertical fence 56 in an inclined manner toward the unit wall 4 side, and a plurality of the blowout openings 9 are formed at predetermined intervals in the vertical direction over the entire vertical area of the vertical fence 56. It has been done.

This vertical gutter 56 is connected to the unit wall 4 constituting the bathroom wall by a hinge 6 so as to be opened and closed. The unit wall 4 of this example has a structure in which a space 4S is formed.
A primary coil 17a is provided on the hinge portion 6 side in the unit wall 4, and a secondary coil 18a is provided in the vertical shaft 56 so as to face the primary coil 17a. Electric power can be sent to the secondary coil 18a by induction, a structure without wiring can be obtained, and the sirocco fan 7 can be rotated by supplying power to the sirocco fan 7 satisfactorily.

  Furthermore, a primary coil 17b is also provided in the unit wall 4 at a position indicated by an imaginary line, and a secondary coil 18b indicated by an imaginary line is provided at a position on the outlet 9 side in the vertical rod 56. In such a structure, when the door 5 is opened toward the unit wall 4 with the hinge portion 6 as the center, the primary coil 17b and the secondary coil 18b are aligned to face each other, and the primary coil 17b to the secondary coil are aligned. Electric power can be sent to 18b by electromagnetic induction, and even when the door 5 is open, the sirocco fan 7 can be rotated to allow outside air to flow along the unit wall 4 from the air outlet 9, especially on the door 5 side. Since mold tends to occur on the unit wall 4, it is possible to prevent mold from being applied to the unit wall 4 near the door 5 by reliably applying outside air to the entire area in the vertical direction.
