Description

[Detailed Description of the Invention] This invention relates to a simple ventilation device of the type that is installed through the wall of a house in order to promote natural ventilation between the inside and outside of a room.

In regions with unique climatic conditions such as the Nansei Islands, many of these types of goods are needed.
Conventional ventilation systems cannot prevent the intrusion of rainwater, dust, and small insects, and if the structure emphasizes these measures, the ventilation function will deteriorate and the purpose of a simple ventilation system cannot be achieved. was occurring.

This idea aims to provide a ventilation system that can eliminate the above-mentioned drawbacks, ensure the stability of the ventilation function, and is also highly decorative. It is a deep bowl-shaped main body with an outside air introduction hole that slopes toward the bottom on the inner peripheral wall, and the space between the double walls is used as a ventilation path. This ventilation system is characterized by having an inclined ventilation hole with a net communicating with the ventilation passage, and necessary decorations arranged within the opening area on the front surface of the main body.

Next, an embodiment based on the present invention will be described.
In the drawing, 1 is a deep bowl-shaped body made of pottery;
2 is an inner and outer double-walled space that serves as a ventilation path; 3 is a required number of outside air introduction holes provided in the inner peripheral wall 4 of the main body;
The outside air intake hole is slanted toward the bottom of the main body to prevent rainwater from entering. In addition, 5 in the figure is a ventilation hole provided at the bottom of the outer wall 6 of the main body.A net 7 is attached to this ventilation hole to prevent the intrusion of small insects, and a synergistic effect with the outside air introduction hole 3 prevents the intrusion of dust. The holes are slanted to prevent this. Furthermore, 8 is a drain outlet, 9 is a Shisa area placed within the opening area on the front of the main body 1, and a decorative drawing such as a family crest, and 10 is an annular groove provided on the outer periphery of the main body to improve connection with the wall surface of the house (mainly concrete wall). , 11 indicate screw holes.

By fitting a required number of deep bowl-shaped main bodies 1 to the required locations on the wall of the house, dust and dirt can be removed indoors and outdoors due to the shapes of the ventilation holes 5, the double wall space 2, the outside air introduction holes 3, and the presence of the net 7. The intrusion of small insects can be prevented, and the intrusion of rainwater can be prevented by the synergistic effect of the ventilation hole 5 and the outside air introduction hole 3 and the depth of the space 2.

In regions with long summers, such as the Nansei Islands, multiple such simple ventilation devices are installed and it is necessary to constantly encourage ventilation, but the article according to the present invention prevents the intrusion of rainwater, dust, and small insects as described above. On the other hand, there are many typhoons, and even in these cases, it can prevent rainwater from entering, so it is very useful.In addition, it has a place for Shisa and family crests, so it is very useful. It has the effect of satisfying the local custom of always attaching a statue to a house as a guardian deity.
