- FIG. 6 is a cross sectional view of a ventilation vent cap according to the third exemplary embodiment and an exhaust stream.
- shielding portion 38 which has circular bottom surface 38 a , is composed of cones 33 and 34 having different base angles 33 a and 34 a , respectively, instead of being in the shape of a cone.
- Shielding portion 38 projects into air passage 9 . More specifically, shielding portion 38 is a combination of cone 33 having base angle 33 a and cone 34 having base angle 34 a. Base angle 34 a is smaller than base angle 33 a. The use of shielding portion 38 having such a shape allows exhaust streams 24 and 25 to flow more smoothly along cones 33 and 34 , thereby preventing an increase in the pressure loss and a decrease in the performance of the ventilator.
- Base angle 33 a is preferred to be large so that exhaust streams 24 and 25 can be prevented from flowing toward exterior wall 1 , but large base angle 33 a requires shielding portion 38 to have a large thickness B.
- the large thickness B causes shielding portion 38 to block opening 21 of cylindrical main body 5 , making it necessary to increase a distance C between exterior wall surface 1 a and circular bottom surface 38 a.
- shielding portion 38 is composed of two cones 33 and 34 , and base angle 34 a of cone 34 is smaller than base angle 33 a of cone 33 . This allows exhaust streams 24 and 25 to flow along cones 33 and 34 , while shielding portion 38 can be as thin as possible.
- Exhaust streams 24 and 25 flow as follows. As approaching cone 34 , exhaust streams 24 and 25 flow radially outward along the surface of cone 34 . When reaching cone 33 , exhaust streams 24 and 25 flow along cone 33 , and leave ventilation vent cap 18 at lower end 11 , thereby being discharged to exterior 3 . Exhaust streams 24 and 25 never flow toward exterior wall 1 because they have components in the direction of base angle 33 a with respect to exterior wall surface 1 a at lower end 11 .
- Ventilation vent cap 18 has a lower pressure loss (a larger amount of ventilation) with increasing distance between center 20 of shielding portion 38 and outdoor-side end surface 6 .
- lower end 11 has a larger angle (base angle 33 a )
- exhaust streams 24 and 25 are more apart from exterior wall surface la, making exterior wall 1 more soil resistant (it is desirable that the maximum angle of lower end 11 is 70°).
- shielding portion 38 is composed of cones 33 and 34 , allowing an appropriate distance between center 20 and outdoor-side end surface 6 , thereby reducing an increase in the amount of ventilation and increasing the angle of lower end 11 .
- exterior wall 1 can be more soil resistant, and the projection allowance C can be smaller, making ventilation vent cap 18 slim and aesthetically designed.
- Shielding portion 38 is composed of two cones 33 and 34 in the present third exemplary embodiment, but may alternatively be composed of three or more cones.
- a fourth exemplary embodiment of the present invention the same components as in the second exemplary embodiment are denoted by the same reference numerals, and the description thereof is omitted. The following description will be focused on the difference between the second and fourth exemplary embodiments.
- the fourth exemplary embodiment differs from the second exemplary embodiment in the shape of the shielding portion.
- FIG. 7 is a cross sectional view of a ventilation vent cap according to the fourth exemplary embodiment, and an exhaust stream.
- shielding portion 48 is composed of spherical surfaces 42 and 43 having different radiuses, instead of being in the shape of a cone. Shielding portion 48 projects into air passage 9 .
- Shielding portion 48 which is composed of two spherical surfaces 42 and 43 , can smoothly change the direction of exhaust streams 24 and 25 that have passed through the interior from a straight-ahead direction J to a blow-off direction G. This reduces an increase in the amount of ventilation.
- exhaust stream 24 flows toward exterior 3 at an angle substantially orthogonal to exterior wall 1 without soiling exterior wall 1 .
- the surface of shielding portion 48 is composed of two spherical surfaces 42 and 43 smoothly connected to each other without ridges. As a result, no problems occur such as dust accumulation in the ridges, so that the surface of shielding portion 48 , and hence the appearance of the product itself can be kept clean.
- the ventilation vent cap according to the present invention is useful as, for example, an outdoor hood mounted on the exterior wall of a building.

exhaust stream 17 passes through cylindricalmain body 5 and then flows along the surface ofcone 14 ofshielding portion 8. Apex 13 ofcone 14 is located above openingupper end 5 a of cylindricalmain body 5, so thatexhaust stream 17 can be prevented from flowing towardcover portion 10 and then turning into turbulent flow in the vicinity ofcover portion 10. Thus,exhaust stream 17 passed through cylindricalmain body 5 is smoothly discharged along the surface ofcone 14 ofshielding portion 8. This maintains the low pressure loss and high performance of the ventilator. - As shown in
FIG. 2 ,exhaust stream 17leaves air passage 9 throughlower end 11 ofcircular bottom surface 8 a substantially at an angle of θ with respect toexterior wall surface 1 a. This preventsexhaust stream 17 from colliding withexterior wall surface 1 a, so thatexterior wall surface 1 a can be kept clean. -

The following description will be focused on the difference between the first and second exemplary embodiments. The second exemplary embodiment differs from the first exemplary embodiment in the shapes of
shielding portion 8 andcover portion 10. -
FIG. 4 is a cross sectional view of a ventilation vent cap according to the second exemplary embodiment, and an exhaust stream.FIG. 5 is a perspective view of the ventilation vent cap and the exhaust stream. As shown inFIG. 4 ,shielding portion 8 is in the shape ofcone 23 whoseapex 13 faces cylindricalmain body 5. The base angle ofcone 23 is δ. As shown inFIG. 5 ,cover portion 10 has cover rim on an outdoor-side-end-surface side 16 on the outdoor-side end surface 6 side, cover rim on the outdoor-side-end-surface side 16 being longer than cover rim on a circular-bottom-surface side 15 on thecircular bottom surface 8 a side ofshielding portion 8. Thus,cover portion 10 hasend side 26, which extends obliquely downward fromcircular bottom surface 8 a to outdoor-side end surface 6. - When ventilation is started with the above-described ventilation vent cap, as shown in
FIG. 4 ,exhaust stream 24 passes through the lower part of cylindricalmain body 5 and then flows along the surface ofcone 23 ofshielding portion 8. - On the other hand, as shown in
FIG. 5 ,exhaust stream 25 passes through the upper part of cylindricalmain body 5, and flows along cover rim on the circular-bottom-surface side 15 on thecircular bottom surface 8 a side ofcover portion 10, then passes through a substantially V shaped region S formed by the region ofcover portion 10 that is in the vicinity ofend side 26 andshielding portion 8, thereby being discharged toexterior 3 from underend side 26. - At this moment, as shown in
FIG. 5 ,exhaust stream 25 flowing alongcover portion 10 is discharged toexterior 3 from the vicinity of an apex T of the region S on the shielding-portion 8 side.Exhaust stream 24, on the other hand, is discharged toexterior 3 smoothly from underend side 26. This prevents an increase in the pressure loss and a decrease in the performance of the ventilator. - It is desirable that the angle δ is in the range of 30° to 70°.
