DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 2 and 3, a box body 30 and a grill 31 form a box-shaped main body 32. The box 30 includes a pair of second vertical plates 30c and an intermediate horizontal plate 30d opposed to a pair of first vertical plates 30b opposed to the upper plate 30a. A first casing 33 and a second casing 34 are attached across the upper plate 30a and the intermediate horizontal plate 30d.
[0020]
A first blade (sirocco fan) 35 is rotatably provided in the first casing 33 to constitute a circulation fan 36, and an intake side of the circulation fan 36 is opened to a circulation intake port (bell mouth) 37. The discharge side is open to the circulation discharge port 38. The circulation discharge port 38 is provided with a heater 39.
[0021]
A second blade (sirocco fan) 40 is rotatably provided in the second casing 34 to constitute a ventilation fan 41. The intake side of the ventilation fan 41 opens to the ventilation inlet 42, the discharge side opens to the ventilation outlet 43, and the ventilation outlet 43 opens outdoors by an exhaust duct 44.
[0022]
A part of the circulation intake port 37, the circulation discharge port 38 and the ventilation intake port 42 communicates with the interior of the bathroom through the ventilation portion 45 of the grill 31, and a part of the ventilation intake port 42 is the air passage 46. Communicated with the room air inlet 47. The other room air inlet 47 is open to the other room, for example, a toilet, through a ventilation duct 48.
[0023]
The air passage 46 is composed of an inner chamber 46a of the box 30 and an opening 46b formed in the intermediate horizontal plate 30d and a telescopic duct 46c. The telescopic duct 46c has a U-shaped fixed duct 50 that is fixed to the intermediate horizontal plate 30d and one of the second vertical plates 30b, and a U-shaped cross-section that is movably provided along the fixed duct 30. A movable duct 51 in the form of a ring.
[0024]
As shown in FIG. 4, the movable duct 51 has a flange 52, and a fixing tool 54 is screwed and attached to the intermediate horizontal plate 30 d through a long hole 53 formed in the flange 52. The other end of the movable duct 51 is opposed to the ventilation inlet 42, and an upward piece 55 is provided to constitute an intake air volume distribution adjusting device.
[0025]
Therefore, if the movable duct 51 is extended and operated, the overlap amount of the rising plate 55 and the ventilation inlet 42 is increased, the opening area of the air passage 46 and the ventilation inlet 42 is increased, and the ventilation intake is increased. Since the opening area between the mouth 42 and the bathroom is reduced, the amount of air sucked by the ventilation fan 41 is large in the toilet and small in the bathroom.
[0026]
Further, if the movable duct 51 is contracted and operated, the overlap amount between the rising plate 55 and the ventilation inlet 42 is reduced, the opening area of the air passage 46 and the ventilation inlet 42 is reduced, and the ventilation inlet 42 and the bathroom are reduced. Since the opening area with the interior increases, the amount of air sucked by the ventilation fan 41 is small in the toilet and large in the bathroom.
[0027]
The position adjustment (air volume adjustment) of the movable duct 51 described above is performed with the grille 31 removed. A scale 56 is formed in the fixed duct 50 so that the position of the movable duct 51, that is, the opening area of the air passage 46 and the ventilation inlet 42 can be visually confirmed.
[0028]
Therefore, when installing a bathroom ventilation dryer for two rooms, for example, when the toilet is large, the movable duct 51 is extended to operate the intake air volume in the toilet to be large, and when the toilet is small The movable duct 51 is contracted and operated to reduce the intake air volume in the toilet.
[0029]
【The invention's effect】
According to the first invention, the air in the bathroom can be circulated, heated and circulated, and the inside of the bathroom and other rooms can be ventilated.
[0030]
Moreover, since the ratio of the air intake air volume in the bathroom and the other air intake air volume by the ventilation fan 41 can be increased or decreased by the intake air volume distribution adjusting device, it can be adjusted according to the size of the bathroom, the size of other rooms, duct resistance, etc. The required air volume can be ventilated.
[0031]
This makes it possible to sufficiently ventilate the bathroom and other rooms by using the ventilation fan 41 as a small capacity.
[0032]
Further, by extending and contracting the telescopic duct 46c, the amount of intake air from the bathroom and the amount of intake air from other rooms can be adjusted.
[0033]
According to the second invention, by moving the movable duct 51 with the grille 31 removed, the intake air volume from the bathroom and the intake air volume from other rooms can be adjusted. It can be hidden by covering with 31.
[0034]
This makes it easy to adjust the intake air volume and improve the appearance during normal times.
