Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vent cap installed on a wall surface of a building for ventilation, and particularly to a vent cap suitable for a tiled wall surface.

[0002]

[Prior art]

 The vent cap is used as an external terminal device of the ventilation system and is usually installed on the wall surface of the building where the tip of the ventilation path is open. In order to eliminate it and enhance the appearance and design of the building, various measures have been taken to attach exterior tiles to the hood. One of the important issues regarding the tile installation is how to secure the fixing force to the tile. In other words, since the vent cap is attached to the outer wall, it is necessary to secure the tile fixing force sufficiently to prevent the tile from falling. For example, Japanese Patent Application No. 3-111103 and Japanese Patent Application No. 3-112703 show examples of such a device. Among these, in Japanese Patent Application No. 3-111103, the hood portion of the vent cap has a holder structure, and the fixing force is secured by mechanically holding the exterior tile. Also, in Japanese Patent Application No. 3-112703, the hood is formed as a ceramic tile adhering cell divided by tile joint partitions, and the side surface of the tile is also adhered to obtain a fixing force. There is.

All of these have sufficient performance in terms of the tile fixing force. However, there is a problem of complicated structure. Further, preferably, it is desirable to attach tiles by a process similar to the process of applying tiles to the surrounding walls, but there is a drawback that such a process is not possible.

[0004]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a tile-decorative vent cap which has a relatively simple structure, can secure the fixing force of the tile, and can be mounted with the tile by the same treatment as the surrounding wall.

[0005]

[Means for Solving the Problems]

 The tile-decorative vent cap according to the present invention is provided with a mounting surface portion on which the same type of tile as the tile used for the wall surface to be installed can be selected and mounted, and the mounting surface portion has a fixing surface for the tile adhering material. The tile adhering surface for the tile adhering material is formed by attaching a planar perforated material having a large number of through holes in a state of being slightly floated above the bottom surface of the mounting surface portion. The tile decorative type vent cap according to the present invention has the same basic structure as described above, and the fixing surface for the tile adhering material is formed by the uneven surface material having many unevenness on the surface. There is.

[0006]

[Action]

 As described above, according to the present invention, since the fixing surface is provided by the perforated material having a through hole or the uneven surface material in the mounting surface portion, it is generally used for sticking tiles such as tile mortar. A sufficient anchoring force can be given to the adhesive material such as. Therefore, the tiles can be attached in the same manner as tiles are attached to the surrounding wall, and the same level of fixing force as that of the surrounding wall can be provided. Further, since the structure is simply attached with the perforated material and the uneven surface material, the structure is simpler than that of the conventional structure.

[0007]

【Example】

 Embodiments of the present invention will be described below. As shown in FIGS. 1 and 2, the vent cap 1 according to this embodiment includes a fitting cylinder 2 and a hood portion 3.

The fitting cylinder 2 is fitted and attached to the ventilation duct D opened to the hollow portion H provided on the wall surface W, and is formed of, for example, aluminum or stainless steel.

The hood portion 3 is for covering the opening at the tip of the fitting cylinder 2, is formed of the same material as the fitting cylinder 2 in a rectangular shape, and has a tile T attached to the front surface thereof. A mounting surface portion 4 is formed, and a ventilation opening 6 having a louver 5 is provided below the mounting surface portion 4. The mounting surface portion 4 is formed by being dropped into a concave shape having a depth d, and the lath net 7 is slightly floated from the bottom surface of the mounting surface portion 4 as "a planar perforated material having a large number of through holes". It is provided in an upright position to form a "fixed surface". The depth d of the mounting surface portion 4 is the sum of the thickness of the tile T, the thickness of the lath net 7 and the filling space of the mortar as the “tile adhering material”. Here, the reference numeral 8 indicates an inclined plate for preventing rainwater blown in, runoff water from the duct side and the like from staying in the hood portion 3.

Instead of the lath net 7, a so-called punching plate can be used as “a planar perforated material having a large number of through holes”. In this case as well, the mounting surface portion 4 is the same as the lath net 7. Installed in a state of being slightly floated from the bottom of the.

In the vent cap 1 thus configured, the fitting cylinder 2 is fitted and attached to the ventilation duct D, and the hood portion 3 is embedded in the recess H so as to be flush with the wall surface W. Installed on W. After the mortar is sufficiently coated on the lath net 7 provided on the mounting surface portion 4, a tile T of the same type as the surrounding wall is attached (see FIG. 4). As a result, the vent cap 1 has the same tile appearance as the wall surface W to be installed without fear of falling tiles, even though the vent cap 1 has a simple structure, and a working state that is very harmonious with the wall surface W is obtained. be able to.

In particular, in the case of the above-mentioned embodiment, since the tile T is attached to the hood portion 3 in a state of being dropped, the fixing is more reliable, and the hood portion 3 is fixed from the wall surface W 1. Since it does not project, it is inconspicuous even when viewed from an angle, and it can be more in harmony with the appearance of the wall surface W. Further, since the ventilation opening 6 is provided in the lower portion of the front surface of the hood portion, it is difficult for rainwater and the like from entering from the outside, so that there is an advantage that the so-called “rainfall” is improved.

Next, as another embodiment, a case where the uneven surface member 9 shown in FIG. 3 is used for the vent cap 1 instead of the “fixed surface” formed by the lath net 7 will be described. The uneven surface material 9 may be a metal material such as aluminum or stainless steel, but here, it is formed of a ceramic material that is well compatible with a tile adhering material such as mortar. On one surface thereof, a plurality of concave grooves 10 having a reverse taper cross-sectional shape in a so-called dovetail shape are formed in parallel, and convex portions 11 are formed between the concave grooves 10. The surface on which the concave groove 10 and the convex portion 11 are formed faces outward and is provided in close contact with the bottom surface of the mounting surface portion 4 shown in the above-described embodiment. Then, the mortar is applied on the uneven surface material 9 to spread the mortar in the groove 10, and the tile T is attached. When the uneven surface material 9 is formed of a material that is sufficiently compatible with the tile adhering material, the concave groove 10 may be a simple concave groove that does not have a reverse taper sectional shape.

In the above, the vent cap 1 in which the “fixing surface” is provided only on the front surface of the hood portion 3 and the hood portion 3 is embedded in the wall surface W has been described, but the invention is not limited to this, and for example, the wall surface W. Alternatively, the hood portion 3 may be protruded from the wall surface W without providing the hollow portion H. In this case, the tiles T are attached to the entire hood portion 3 by providing a "fixed surface" also on the side surface 12 of the hood portion.

[0015]

[Effect of device]

 As described above, the tile-decorative vent cap according to the present invention is provided with the fixing surface for generating the anchoring force with the tile adhering material, so that the surrounding wall has a relatively simple structure. It is possible to attach tiles similar to the above with the same level of fixing force.
