[0028]
The main body case 34 is provided with an air passage 39A that guides air into the partition wall 39 from the second opening of the duct coupling pipe 12.
[0029]
5 and 6 are explanatory views of the duct integrated pipe 12, a duct connecting portion 41 attached to the main body case 34, a semi-cylindrical exhaust duct connecting portion 42 fixed to the duct connecting portion 41, and one end closed. A semicircular T-shaped intake duct connecting portion 44 and the like closed by the plate 43 are provided.
[0030]
Then, the duct integrated pipe 12 is formed by aligning the flat portion 45 of the intake duct connecting portion 44 with the flat portion 46 of the exhaust duct connecting portion 42 and inserting the intake duct connecting portion 44 into the duct connecting portion 41. .
[0031]
Note that the intake duct connection portion 44 and the exhaust duct connection portion 42 are both formed in a semicircular cross section, but the present invention is not limited to this, and the intake duct connection portion 44 and the exhaust duct connection portion 42. It goes without saying that the cross section of the above may be formed into a quadrangle.
[0032]
However, as described above, the intake duct connecting portion 44 and the exhaust duct connecting portion 42 are preferably combined with each other and then have a flat portion so as to be integrated by means such as taping.
[0033]
In addition, although the case where the intake duct connection portion 44 has a T shape has been described, the present invention is not limited to this, and may be an L shape. However, since the both ends can be fixed by taping or the like by forming the T shape in this way, the advantage that the coupling between the intake duct connecting portion 44 and the exhaust duct connecting portion 42 can be strengthened. There is.
[0034]
In this embodiment, the duct coupling pipe 12 is configured by combining the intake duct connecting portion 44 and the exhaust duct connecting portion 42. However, the present invention is not limited to this configuration. For example, the duct connecting tube 12 may be integrally formed with synthetic resin. The air path shown by the solid line arrow and the air path shown by the dotted line arrow in FIG.
[0035]
An opening that forms an air path indicated by a solid line arrow at one opening (the main body case 34 side) of the duct coupling pipe (exhaust duct) 12 corresponds to the first opening, and one of the duct coupling pipe (exhaust duct) 12 ( The opening that forms the air path indicated by the dotted arrow at the opening on the main body case 34 side corresponds to the second opening.
[0036]
The second opening is connected to the bathroom ventilation inlet 38 through the air passage 39A and the partition wall 39.
[0037]
FIG. 7 is a view showing a procedure for attaching the duct integrated pipe 12 to the main body case 34.
[0038]
In this figure, the procedure for attaching the duct integrated pipe 12 to the main body case 34 is as follows. First, the hand is taken out from the inside of the main body case 34 of the attached bathroom heater 10 to grip the duct integrated pipe 12 and Pull in. Thereafter, the nail plate 40 is inserted and the duct integrated pipe 12 is fixed to the main body case 34.
[0039]
Since the ventilation fan is a centrifugal fan 47 provided with a plurality of the same impellers as the circulation fan 37, air is sucked from the axial direction and discharged in the circumferential direction.
[0040]
For this reason, when the opening of the intake duct connecting portion 44 is located on the peripheral surface of the centrifugal fan 47, there arises a problem that the air in the bathroom is blown out to the dressing room through the intake duct connecting portion 44.
[0041]
Therefore, the air passage 39A as described above is formed in the main body casing 34.
[0042]
As a result, in the centrifugal fan (exhaust fan) 47, the air in the bathroom and the air in the dressing room flow as indicated by the dotted lines shown in FIG. 8, and the air discharged from the centrifugal fan 47 is supplied to the exhaust duct connecting portion. It flows through 42.
[0043]
Thus, since the air in the dressing room is sucked into the main body 11 of the bathroom heater by the intake duct 14 and is exhausted through the exhaust duct 13 together with the air in the bathroom, the bathroom heater 10 is provided only in the bathroom. Even in this case, the dressing room can be ventilated and exhausted by a single exhaust duct 13, eliminating the need for a dedicated ventilator or bathroom heater 10 in the dressing room, thus increasing costs. In addition to being able to suppress, a plurality of exhaust ducts 13 are not disposed behind the ceiling, so that it is possible to prevent deterioration in workability and maintainability.
[0044]
【The invention's effect】
As described above, according to the present invention, the exhaust duct and the intake duct that forms the air passage are connected to the main body case by the duct integrated pipe that forms a part of the exhaust duct. Even when a heater is provided, the dressing room can be ventilated and exhausted with a single exhaust duct.
[0045]
Further, the amount of air sucked into the exhaust fan by using the partition wall can be appropriately distributed between the bathroom and the dressing room, and the exhaust of both the rooms can be surely performed.
