Description

  The present invention relates to a ventilating device for a building, and more particularly, can effectively prevent the outer wall of a building below the venting port from being soiled, has good appearance, and is damaged during transportation. The present invention relates to a ventilating device for a building that can prevent this.

  In general, when installing a ventilating device in a building, in order to prevent rainwater from entering the ventilating space between the venting device and the outer wall, the portion where the venting device and the outer wall contact is sealed with caulking material. It is. However, dirt easily adheres to the surface of the caulking material. When rainwater flows on the surface of the caulking material, the dirt adhering to the surface of the caulking material is washed away by the rainwater, and when the rainwater flows down the wall of the building, There is a problem that streaky dirt is generated on the wall surface.

  Therefore, the ventilating apparatus is usually provided with a draining plate that guides rainwater flowing down on the seal surface so as to be separated from the outer wall of the building.

  When the horizontal length of the venting device of this draining board is equal to the width of the venting device, it is difficult to guide rainwater flowing down on the sealing surface to the draining plate, and it flows down on the outer wall of the building, Streaks of dirt were sometimes generated on the outer wall of the building.

  Therefore, by making the horizontal length of the venting device of the draining plate larger than the width of the venting device, the rainwater flowing down on the sealing surface is effectively guided to the draining plate, and the rainwater is separated from the outer wall of the building. There has been proposed a ventilator that can be guided as described above (for example, JP-A-8-303830).

JP-A-8-303830

  Thus, by making the lateral length of the ventilating device of the draining plate larger than the width of the ventilating device, it becomes possible to reliably guide rainwater flowing down on the surface of the caulking material to the draining plate. However, when the horizontal length of the venting device of the draining board is made larger than the width of the venting device, not only the appearance is bad, but also when transporting the venting device to which the draining plate is attached, The right and left ends of the vent may be bent and damaged, and it is said that extra work and costs are required for packing the vent opening device to prevent the left and right ends of the draining plate from being bent during transportation of the vent opening device. There was a problem.

  Therefore, the present invention can effectively prevent the outer wall of the building from being contaminated due to the rainwater flowing down the surface of the caulking material, has good appearance, and has a draining plate attached. It is an object of the present invention to provide a building ventilating device that can effectively prevent the left and right end portions of the draining plate from being bent and broken when the ventilating device is transported.

  An object of the present invention is a ventilator device that can be attached to an outer wall of a building and has an opening communicating with a vent formed in the outer wall, wherein the opening on the surface of the ventilator device that faces the outer wall. The caulking material filling part that is provided at a position surrounding the upper part and both side parts of the part and that can be filled with a caulking material that seals between the outer walls and the lower part of the ventilating device is provided to fill the caulking material filling part A draining member that receives the water flowing down on the caulking material and guides the water away from the outer wall, and the lateral length of the venting device of the draining member is substantially equal to the width of the venting device. A ventilator device comprising a guide member extending obliquely upward toward a side surface of the ventilator device at a lower end portion of the caulking material filling portion surrounding the both side portions of the opening. It is made.

  During the rain, rainwater that pours down flows on the upper surface of the ventilator device, and a part of it flows down on the side of the ventilator device and on the caulking material filled in the caulking material filling part. Because dirt tends to adhere, the rainwater flowing down on the caulking material contains dirt adhering to the surface of the caulking material, and the rainwater flowing down on the caulking material is delivered to the outer wall surface of the building, and passes over the outer wall surface. When flowing down, streak-like dirt often occurred on the outer wall surface of the building. For this reason, in the conventional ventilating device, the lateral length of the venting device of the draining member that receives rainwater flowing down on the caulking material and guides it away from the outer wall of the building is made larger than the width of the ventilating device. It was configured to reliably receive the rainwater flowing down on the caulking material by the draining member, but when the lateral length of the venting device of the draining member is made larger than the width of the venting device as described above Not only looks good, but also when transporting a venting device with a draining member attached, the left and right ends of the draining member may bend and break, and when transporting the venting device, In order to prevent the right and left ends of the draining member from being bent, there is a problem that extra labor and cost are required for packing the ventilating apparatus. However, according to the present invention, since the lateral length of the ventilating device of the draining member and the width of the venting device are substantially equal, not only the appearance is good, but also the ventilating device to which the draining member is attached is transported. In doing so, the left and right end portions of the draining member are bent and there is no risk of breakage, and the lower end portion of the caulking material filling portion is provided with a guide member extending obliquely upward toward the side surface of the ventilating apparatus. Even if the length of the draining member is substantially the same as the width of the ventilation opening device, the rainwater that flows down on the caulking material and reaches the lower end of the filling portion of the caulking material is surely secured to the draining member by the lower surface of the guide member. Therefore, rainwater that has flowed down on the caulking material is transferred to the outer wall surface of the building, and streaks due to the flow down on the outer wall surface are generated on the outer wall surface of the building. It becomes possible to reliably prevent that.

  In a preferred embodiment of the present invention, the caulking material filling portion provided at a position surrounding the both side portions of the opening extends in a substantially vertical direction.

Since a guide member extending diagonally upward toward the side of the device is provided, even if the lateral length of the ventilating device of the draining member is substantially equal to the width of the venting device, it flows down on the caulking material. It is possible to reliably guide the rainwater on the draining member by the guide member.

  In the present invention, the guide member is provided so as to have an angle of 25 to 50 degrees with respect to the side surface of the ventilating apparatus, and preferably provided so as to have an angle of 30 to 45 degrees. When the angle of the guide member with respect to the side surface of the ventilating apparatus is less than 25 degrees, the width of the caulking material filling portion becomes narrow, and the gap between the ventilating apparatus and the outer wall cannot be sufficiently sealed. When the angle of the guide member with respect to the side surface of the mouth device exceeds 50 degrees, the rainwater that has flowed down on the caulking material and reached the lower end of the filling portion of the caulking material may fall to the ground surface as it is, and the guide member This makes it difficult to guide rainwater onto the draining member as desired, which is not preferable.

  In this embodiment, when fixing the ventilating device 1 to the outer wall 2 of the building, in order to prevent rainwater from entering the venting port 3 from between the venting device 1 and the outer wall 2, the caulking material is filled. The portion 15 is filled with a caulking material so that the space between the ventilating apparatus 1 and the outer wall 2 is sealed.

  As shown in FIG. 2 and FIG. 3, three elastic members 6 a, 6 b, 6 c are formed on the surface of the cylindrical member 6, and these are fitted when the cylindrical member 6 is fitted into the vent 3. The elastic members 6a, 6b, and 6c press the inner wall of the vent 3 so that the cylindrical member 6 is fixed in the vent 3 and the base member 7 is fixed to the outer wall 2 of the building. It is configured.

  As shown in FIGS. 2 and 3, the base member 7 to which the tubular member 6 is attached is formed on the opening surface of the opening 11 in the opening 11 formed on the surface of the hood member 5 on the outer wall 2 side. And the opening 11 is closed.

  As shown in FIG. 3, the base member 7 is fixed to the hood member 5 at six locations by blind rivets 7a, 7b, 7c, 7d, 7e, and 7f.

  As shown in FIGS. 2 and 3, a draining plate forming portion 25 is formed on the lower edge portion of the base member 7. The draining plate forming portion 25 is substantially perpendicular to the surface of the base member 7 and has a wall portion 26 having substantially the same height as the plate-like wall 14, and substantially parallel to the surface of the base member 7 from the top of the wall portion 26. A flat plate portion 27 that extends and a draining plate 28 that extends obliquely downward and forward (in a direction away from the outer wall 2) from the lower edge portion of the flat plate portion 27 are provided. As shown in FIG. 3, the lateral length of the ventilating apparatus 1 of the draining plate 28 is set to be substantially equal to the width of the hood member 5.

  The draining plate 28 guides rainwater that has flowed down on the draining plate 28 so as to be separated from the outer wall 2, and as shown in FIGS. 2 and 3, both side portions 28 a, 28 a of the draining plate 28 are The rainwater which is bent at a substantially right angle with respect to the surface of the draining plate 28 and has flowed down to the draining plate 28 is prevented from flowing sideways, and at the same time, the strength of the draining plate 28 is improved.

  Further, as shown in FIG. 3, the upper edge portions 28 b and 28 b of the draining plate 28 on the outer wall 2 side are bent so as to be substantially parallel to the surface of the base member 7, and the rainwater that has flowed down to the draining plate 28. Is prevented from flowing down to the outer wall 2 side, and the strength of the draining plate 28 is improved.

  As shown in FIG. 2, the louver 30 is fixed near the lower edge of the base member 7 by screws 32 a and 32 b. The gallery 30 is configured to guide air flowing into the internal space of the hood member 5 downward and away from the outer wall 2 through the vent 3 and the cylindrical member 6 from the room.

  As shown in FIG. 2 and FIG. 3, guide members 35, 35 extending obliquely upward are formed in the caulking material filling portion 15 at the left and right ends of the wall portion 26 of the draining plate forming portion 25, respectively. Yes. In the present embodiment, the guide members 35 and 35 are formed at an angle of 40 degrees with respect to the plate-like wall 14.

  FIG. 4 is a schematic rear view of the ventilating apparatus showing a state where the caulking material is filled in the caulking material filling unit 15.

  As described above, when attaching the ventilating apparatus 1 to the outer wall 2 of the building, the caulking material filling portion 15 is filled with the caulking material. As shown in FIG. 4, the caulking material is at the same height as the plate-like wall 14 formed in the hood member 5 around the opening 11 in the caulking material filling portion 15 in a substantially rectangular shape, and The seal portion 18 is formed by filling so that the cross section is substantially rectangular.

  The guide members 35 and 35 are not necessarily formed so as to form an angle of 40 degrees with respect to the plate-like wall 14, and the guide members 35 and 35 are 25 degrees to 50 degrees, preferably 30 degrees. It has an angle of 45 degrees. When the angle of the guide members 35 and 35 with respect to the plate-like wall 14 is less than 25 degrees, the width of the seal portion 18 becomes narrow and the space between the ventilating apparatus 1 and the outer wall 2 cannot be sufficiently sealed. In the case where the angle of the guide members 35, 35 with respect to the plate-like wall 14 exceeds 50 degrees, the rainwater may enter the vent 3. The rainwater that has flowed down and has reached the lower end of the seal portion 18 falls as it is, and guides the rainwater along the lower surfaces of the guide members 35 and 35 to the inside of the hood member 5 as desired. It is difficult to lead to 28, which is not preferable.

  In the ventilating apparatus 1 according to a preferred embodiment of the present invention configured as described above, rainwater is guided in the following manner when it rains.

  Rainwater that has poured onto the upper surface of the hood member 5 of the ventilating apparatus 1 flows on the upper surface of the hood member 5 and then flows down to the ground, but part of it flows down the left and right surfaces of the hood member 5. Therefore, part of the rainwater flows down along the outer surface of the seal portion 18 filled with the caulking material.

  Since dirt easily adheres to the surface of the caulking material, the rainwater flowing down along the outer surface of the seal part 18 filled with the caulking material contains dirt adhering to the outer surface of the seal part 18.

  Further, since the seal portion 18 filled with the caulking material is in contact with the outer wall 2, the rain water that flows down the outer surface of the seal portion 18, leaves the outer surface of the seal portion 18, and falls downward is It is transferred to the surface of the outer wall 2 and easily flows on the surface of the outer wall 2, and as a result, streaky dirt may occur on the surface of the outer wall 2 of the building.

  Therefore, conventionally, a draining plate 28 having a width larger than the width of the hood member 5 is provided at the lower edge portion of the hood member 5 as a draining plate 28 that receives rainwater that leaves the outer surface of the seal portion 18 and falls downward. The rain water that flows down the outer surface of the seal portion 18 and leaves the outer surface of the seal portion 18 is transferred to the draining plate 28 so that it does not flow on the surface of the outer wall 2, so Preventing the occurrence of dirt.

  However, when the horizontal length of the ventilating device 1 of the draining plate 28 is larger than the width of the hood member 5, not only the appearance is bad, but the ventilating device 1 to which the draining plate 28 is attached is transported. In order to prevent the right and left end portions of the draining plate 28 from being bent and damaged, and to prevent the right and left end portions of the draining plate 28 from being bent when the ventilating device 1 is transported. There has been a problem that the packaging of the apparatus 1 requires extra labor and costs.

  Therefore, in the present embodiment, the left and right end portions of the wall 26 of the draining plate forming portion 25 extend obliquely upward into the caulking material filling portion 15, and rainwater is disposed inside the hood member 5 along the lower surface thereof. Guide members 35 and 35 are formed so as to guide the rainwater flowing down the outer surface of the seal portion 18 onto the draining plate 28 by the guide members 35 and 35.

  That is, according to the present embodiment, rainwater that flows down the outer surface of the seal portion 18 filled with the caulking material and reaches the lower end portion of the seal portion 18, along the lower surfaces of the guide members 35, 35, Guided inside the hood member 5. As a result, even if the horizontal length of the drainage plate 28 and the width of the hood member 5 are equal to each other, the rainwater is surely delivered to the drainage plate 28, and therefore travels along the outer surface of the seal portion 18. The rainwater that has flowed down and reached the lower end of the seal portion 18 is reliably prevented from flowing down on the surface of the outer wall 2, and flows along the surface of the seal portion 18. It is possible to reliably prevent the occurrence of streaky dirt caused by flowing down the surface of the outer wall 2 of the building.

  Further, according to the present embodiment, since the lateral length of the ventilating apparatus 1 of the draining plate 28 is substantially equal to the width of the hood member 5, the lateral length of the ventilating apparatus 1 of the draining plate 28 is the hood. The appearance is not deteriorated as in the case where the width is larger than the width of the member 5, and the hood member 5 is wider than the hood member 5 in the width direction of the hood member 5 when the ventilation port device 1 including the draining plate 28 is transported. In addition, the left and right end portions of the draining plate 28 protruding outward are not bent and damaged. Furthermore, in order to prevent the left and right end portions of the draining plate 28 protruding outward from the hood member 5 in the width direction of the hood member 5 from being bent, extra labor and cost are required for packing the ventilating apparatus 1. Conventional problems can also be solved.

  FIG. 5 is a schematic rear view of a ventilating apparatus according to another preferred embodiment of the present invention, showing a state in which a caulking material is filled in the seal portion.

  As shown in FIG. 5, in the ventilating apparatus 1 according to this embodiment, the hood member 5 has a substantially dome-shaped cross section.

  In this embodiment, the opening 11 formed on the surface of the hood member 5 on the outer wall 2 side has a substantially dome shape, and the hood member 5 around the opening 11 has a substantially domed plate-like wall 14. The caulking material filling part 15 is formed by the plate-like wall 14 and the outer wall 2 side surface of the outer hood member 5, and the caulking material filling part 15 is filled with the caulking material. Thus, a seal portion 18 is formed.

  Also in this embodiment, the rainwater that has flowed down the outer surface of the seal portion 18 filled with the caulking material into the caulking material filling portion 15 and has reached the lower end portion of the seal portion 18 is hooded by the guide members 35 and 35. Since it is guided inward of the member 5 and reliably delivered to the draining plate 28, it flows down along the outer surface of the seal portion 18, and rainwater that reaches the lower end of the seal portion 18 travels on the surface of the outer wall 2. The streaks that are prevented from flowing down reliably, flow along the surface of the seal portion 18 filled with the caulking material in the caulking material filling portion 15, and the rainwater containing dirt flows down on the surface of the outer wall 2. It becomes possible to reliably prevent the occurrence of the soil on the surface of the outer wall 2 of the building.

  FIG. 6 is a schematic front view of a ventilating apparatus according to another preferred embodiment of the present invention, and FIG. 7 is a schematic longitudinal sectional view of the ventilating apparatus shown in FIG.

  As shown in FIGS. 6 and 7, the ventilating apparatus 51 according to this embodiment includes a base member 57 that is fixed to the outer wall 2 of the building, and a cover member 55 into which the base member 57 is fitted.

  FIG. 8 is a schematic rear view of the ventilation opening device shown in FIG. 6.

  As shown in FIGS. 6, 7, and 8, the cover member 55 has a substantially rectangular cross section, and a gall 58 is formed on the surface opposite to the outer wall 2, and the outer wall of the cover member 55 is formed. An opening 59 is formed on the second side.

  As shown in FIG. 8, an opening 56 is formed on the outer wall 2 side of the base member 57.

  As shown in FIGS. 6, 7, and 8, a seal portion forming member 60 is attached to the surface of the base member 57 on the outer wall 2 side. The seal portion forming member 60 has an L-shaped cross section, and includes an adhesive portion 60 a that is bonded to the surface of the base member 57 on the outer wall 2 side, and a plate-like wall portion 60 b that is substantially perpendicular to the surface of the base member 57. The caulking material filling portion 65 is formed by the plate-like wall portion 60b and the outer wall 2 side surface of the outer base member.

  A draining plate forming portion 70 is formed on the lower edge portion of the base member 57.

  The draining plate forming portion 70 is substantially perpendicular to the surface of the base member 57 and has a wall portion 76 having substantially the same height as the plate-like wall portion 60b, and substantially parallel to the surface of the base member 57 from the top of the wall portion 76. A flat plate 77 extending downward and a draining plate 78 extending obliquely downward and forward (in a direction away from the outer wall 2) from the lower edge of the flat plate 77 are provided.

  As shown in FIG. 8, the lateral length of the vent hole device 51 of the draining plate 78 is set to be approximately equal to the width of the cover member 55.

  The draining plate 78 guides rainwater that has flowed down to the draining plate 78 so as to be separated from the outer wall 2, and both side portions 78 a, 78 a of the draining plate 78 are surfaces of the draining plate 78 as shown in FIG. 7. On the other hand, it is possible to prevent the rainwater which is bent at a substantially right angle and has flowed down to the draining plate 78 from flowing sideways, and at the same time, the strength of the draining plate 78 is improved.

  As shown in FIGS. 7 and 8, both lower end portions of the plate-like wall portion 60 b that is substantially perpendicular to the surface of the base member 57 of the seal portion forming member 60 are bent and obliquely upward in the caulking material filling portion 65. Guide members 63, 63 extending in the direction are formed. In this embodiment, the guide members 63 and 63 are formed so as to form an angle of 40 degrees with respect to the plate-like wall 60b.

  FIG. 9 is a schematic rear view of the ventilating apparatus showing a state in which the caulking material filling unit 65 is filled with the caulking material.

  In attaching the ventilating apparatus 1 to the outer wall 2 of the building, the caulking material filling portion 65 is filled with the caulking material. As shown in FIG. 9, the caulking material is filled in the caulking material filling portion 65 so as to be substantially the same height as the substantially rectangular plate-like wall 60 b and the cross section is substantially rectangular. Thus, a seal portion 68 is formed.

  It is not always necessary for the guide members 63 and 63 to be formed at an angle of 40 degrees with respect to the plate-like wall 60b. The guide members 63 and 63 are 25 with respect to the plate-like wall 60b. The angle may be from 50 degrees to 50 degrees, preferably from 30 degrees to 45 degrees. When the angle of the guide members 63 and 63 with respect to the plate-like wall 60b is less than 25 degrees, the width of the seal portion 68 becomes narrow, and the gap between the ventilation port device 51 and the outer wall 2 cannot be sufficiently sealed. In the case where the angle of the guide members 63, 63 with respect to the plate-like wall 60b exceeds 50 degrees, the rainwater may enter the vent 3 and travel along the outer surface of the seal portion 68. The rainwater that has flowed down and reached the lower end of the seal portion 68 falls as it is, and guides the rainwater along the lower surfaces of the guide members 63 and 63 to the inside of the cover member 55 as desired. It is difficult to lead to 78, which is not preferable.

  In the ventilating apparatus 1 according to a preferred embodiment of the present invention configured as described above, rainwater is guided in the following manner when it rains.

  Rainwater that has poured onto the upper surface of the cover member 55 of the ventilating apparatus 51 flows on the upper surface of the cover member 55 and flows down to the ground, but part of it flows down the left and right wall surfaces of the cover member 55. Therefore, part of the rainwater flows down along the outer surface of the seal portion 68 filled with the caulking material.

  Since dirt easily adheres to the surface of the caulking material, the rainwater flowing down along the outer surface of the seal part 68 filled with the caulking material contains dirt adhering to the outer surface of the seal part 68.

  In addition, since the seal portion 68 filled with the caulking material is in contact with the outer wall 2, the rainwater that flows down along the outer surface of the seal portion 68, leaves the outer surface of the seal portion 68, and falls downward is It is transferred to the surface of the outer wall 2 and easily flows on the surface of the outer wall 2, and as a result, streaky dirt may occur on the surface of the outer wall 2 of the building.

  Therefore, conventionally, as the draining plate 78 that receives the rainwater that leaves the outer surface of the seal portion 68 and falls downward, the draining plate 78 in which the lateral length of the ventilation port device 51 is larger than the width of the base member 57 is used. Rainwater that is provided at the lower edge portion of the base member 57 and flows along the outer surface of the seal portion 68 and leaves the outer surface of the seal portion 68 is transferred to the draining plate 78 so that it does not flow on the surface of the outer wall 2. As a result, the occurrence of stain streaks on the outer wall 2 is prevented.

  However, when the length of the drainage plate 78 in the lateral direction of the ventilation port device 51 is larger than the width of the base member 57, not only the appearance is bad, but also the ventilation port device 51 to which the drainage plate 78 is attached is transported.
