An intermediate member provided with a screw portion on the top plate member, and a hood mainly made of ceramics attached to the top plate member of the intermediate member via an attachment member.

  In addition to the first problem-solving means, the second problem-solving means of the present invention is provided with a peripheral wall raised on the tip side so as to form a smooth concave surface on the outer peripheral edge of the ring main body of the collar portion. That is.

  In addition to the first problem-solving means, the third problem-solving means of the present invention is provided on the outer peripheral edge of the ring main body of the collar portion with a peripheral wall raised so as to form a smooth concave surface, The drainage ridges are integrally formed on the outer side in the radial direction of the peripheral wall.

  In addition to the first problem-solving means, the fourth problem-solving means of the present invention is provided with a peripheral wall raised on the tip side so as to form a smooth concave surface on the outer peripheral edge of the ring main body of the collar portion, Further, the folded portion is provided to be folded back on the rear end side, and a gap is left between the outer peripheral edge of the flange portion.

  According to a fifth problem solving means of the present invention, in addition to the first problem solving means, a plurality of leg members in the intermediate member are inclined and erected so as to approach the center line of the ring plate at equal intervals.

  According to a sixth problem solving means of the present invention, in addition to the fifth problem solving means, the leg member is formed of a strip-shaped plate, and is twisted so as to be inclined with respect to a circumferential tangential direction with respect to the center line of the ring plate, and The leg members are twisted in the same direction.

  The seventh problem solving means of the present invention is that, in addition to the first problem solving means, the hood is detachably attached to the top plate member of the intermediate member by screws.

  The eighth problem-solving means of the present invention is that, in addition to the first or seventh problem-solving means, the intermediate member is detachably attached to a collar portion of the apparatus main body by a screw.

  According to a ninth problem solving means of the present invention, in addition to the seventh problem solving means, the mounting member of the hood has a screw rod screwed to a screw portion of the top plate member fixed to the rear surface of the hood.

  According to a tenth problem solving means of the present invention, in addition to the seventh problem solving means, the attachment member of the hood is integrally formed with a ceramic screw rod screwed to a screw portion of the top plate member on the rear surface of the hood. That is.

  According to an eleventh problem solving means of the present invention, in addition to the seventh problem solving means, a seat plate is fixed to a tip of a screw rod that is screwed into a screw portion of the top plate member in the hood mounting member. A screw hole is provided from the tip of the screw rod to the middle, and the screw is passed through the hole penetrating the center of the hood with the seat plate in contact with the center of the rear surface of the hood. It is screwed and fixed in the screw hole of the rod.

  The thirteenth problem solving means of the present invention is that, in addition to any one of the problem solving means, the hood has a reinforcing sheet attached to the rear surface of the pottery bowl-shaped body.

  By the structure of this invention, the cylindrical apparatus main body inserted in a ventilating hole and the food | hood which covers the ventilating hole were comprised mainly with the product made from earthenware, and both came to be able to connect easily. As a result, the vents can be baked in pottery in the same color as the tiles on the outdoor wall of the house, making it possible to harmonize the appearance that could not be realized in conventional houses. Moreover, the fire damper is not always necessary. Moreover, since the ventilation opening is almost covered with a hood, it cannot be visually recognized from the outside, and there is no sense of discomfort in the exterior of the building.

  When the hood or the intermediate member is detachable from the main body, the hood can be easily removed, and dirt and cleaning can be easily performed. Further, when the shape of the hood is a point-symmetrical shape such as a circle or a regular polygon, the hood has no vertical direction and the applicable range is widened.

Embodiments of the present invention will be described below based on an embodiment shown in the drawings.
1 and 2, a natural ventilation port W1 of the present invention is provided on the outer wall W of a building, and the ventilation port device of the present invention is inserted and attached thereto. The outline of this ventilating device is that a ceramic hood 30 is attached to the tip of a ceramic device main body 10 via a metal intermediate member 20 and a mounting member 40.

  Now, in the apparatus main body 10 made of earthenware, a hole in the cylindrical portion 11 inserted into the ventilation port W1 serves as a ventilation port 11a, and a water return circumferential ridge 11b is provided near the rear end. A circular flange 12 is integrally formed near the tip of the main body. A peripheral wall 12b is provided on the outer peripheral edge of the circular collar body 12a of the circular flange so as to protrude toward the tip side so as to form a smooth concave surface. Further, a draining ridge 12c is integrally formed on the outer side in the radial direction of the peripheral wall.

  Further, the folded portion 12c is folded back to the rear end side, and a gap C is left between the outer peripheral edge of the circular flange portion. The caulking agent C is filled in the gap to prevent rainwater from entering. The peripheral wall 12b changes the direction of the exhaust from the ventilation port in a direction away from the building outer wall W, and the rainwater is guided downward through the draining ridges 12c, thereby preventing the wall surface from being stained.

  In the metal intermediate member 20 shown in FIGS. 2 and 3, a plurality (three in the figure) of leg members 22 are equidistant from the surface of the annular plate 21 attached to the circular flange 12, and the circle center of the annular plate Inclined to approach the line. An equilateral triangular top plate member 23 is fixed to the tips of these leg members, and a nut member 24 is fixed to the back surface thereof. The leg member 22 is formed of a strip-shaped plate, and is twisted so as to be inclined with respect to the tangential direction of the circumference with respect to the center line of the ring plate 21, and is twisted in the same direction by the leg members. By this same direction twist, a swirling flow (arrow B) is generated in the airflow passing through the ventilation port, and the flow resistance of the airflow is reduced.

  The hood 30 is detachably attached to the top plate member 23 of the intermediate member 20 with the attachment member 40. The hood 30 has a metal reinforcing sheet (aluminum foil) 32 attached to the rear surface of a round bowl-shaped main body 31 made of earthenware.

  In the mounting member 40 of the ceramic hood 30, a seat plate 42 is fixed to the tip of a screw rod 41 that is screwed into the screw portion 24 of the top plate member 23, and the screw rod penetrates the seat plate. A screw hole 43 is provided from the front end to the middle. Then, with the seat plate 42 in contact with the center of the rear surface of the hood, a screw 44 is screwed and fixed into the screw hole 43 of the screw rod 41 through a hole penetrating the center of the hood.

  In the above, in order to attach this apparatus to the ventilation port of the building outer wall W1, first, the cylindrical part 11 of the apparatus body 10 is inserted into the ventilation hole, and the circular flange part 12 is pressed against the outer wall W. Next, through the hole 21a of the annular plate 21 of the intermediate member 20, the screw 1 is screwed and fixed to the outer wall W1 through the hole provided in the circular hook body 12a.

  Then, the hood 30 is pressed against the seat plate 42 of the hood mounting member 40, and is screwed into the screw hole 43 of the mounting member through the screw 44 through the hole of the hood. As a result, the screw rod 41 and the seat plate 42 are fixed to the hood 30. Next, the screw rod 41 is screwed into the nut member 24, and the attachment of the hood 30 to the apparatus main body 10 is completed.

  Here, since the screw rod 41 is attached to the hood 30 with screws 44, it is more resistant to fire than attaching with an adhesive. Moreover, since the relatively small-sized screw 44 penetrates the hood 30, the through-hole of the hood 30 only needs to have a small diameter. In addition, since the screw member 41 is screwed into the nut member 24 with a relatively large diameter screw rod 41, the screw rod 41 can be easily screwed into the nut member 24 of the intermediate member 20 even when the hole of the nut member 24 is difficult to see.

  FIG. 4 is another embodiment of the mounting member for the ceramic hood, and a screw rod 41 screwed to the nut member 24 of the top plate member is fixed to the rear surface of the hood via a seat plate and an adhesive. It has been done.

  FIG. 5 shows still another embodiment of the mounting member for the ceramic hood, in which a ceramic screw rod 41 screwed into the nut member 24 of the top plate member is integrally formed on the rear surface of the hood. It is.

  6 and 7 show still another embodiment of the mounting member for the ceramic hood. That is, a seat plate 42 having a claw 42a at its periphery is fixed to the tip of the screw rod 41 that is screwed into the screw portion 24 of the top plate member. A short cylindrical recess 33 is formed concentrically at the center of the inner surface of the hood 30. Then, the seat plate 42 is pushed into the short cylindrical recess 33 through the adhesive D in a state of being secured and fixed. At this time, since the claw 42a is elastically deformed and enters with a reduced radius, the claw is obliquely pressed against the inner surface of the recess, and a retaining action is generated.

  When the member is made of earthenware, it may be reinforced with a sheet or plate such as metal or plastic. In this case, the pottery is prevented from being damaged, and even if broken, the pieces are prevented from falling off.

  The present invention is not limited to the examples and embodiments described above, and includes various modifications without departing from the scope and scope of the claims.

  The present invention is used for a ventilation opening device.
