Description

Multi-direction ventilation apparatus with removable multi-directional branch pipes

The present invention relates to a ventilation apparatus having a detachable multi-directional branch pipe, and more particularly, to form a coupling hole in the ventilation apparatus in a multi-direction and to attach or detach a branch pipe or coupling hole plug for coupling to the coupling hole. It is possible to easily select and change the direction of the required inlet and the number of the necessary inlet according to the interior structure of the specific building, and it is equipped with a detachable multi-directional branch pipe that can provide the functions of the distributor and the ventilation fan as a single unit. It relates to a ventilation device.

In general, a building such as a house or office is provided with a ventilation system to maintain a pleasant indoor environment by forcibly exhausting carbon dioxide, polluted air, and odors accumulated in the internal space to the outside.

The ventilation system is typically installed in the upper part of the ceiling finish of the building, and in addition to the conventional ventilation facilities for effectively exhausting the internal air of each room in response to the structural characteristics of the house, office divided into several rooms Is organized in the following way.

In each of the rooms, an intake grill is installed, and each of the intake grills is connected to an exhaust duct for guiding sucked internal air to the outside. Several exhaust ducts connected to the intake grille of each room and embedded in the ceiling are collected by a distributor, which is connected to an exhaust fan. That is, the air inside each room is collected into the distributor via the exhaust duct through the exhaust fan connected to the distributor, and the indoor air collected by the distributor is forcedly moved to the common exhaust pipe connected to the exhaust fan. It is discharged to the outdoors.

However, such a conventional ventilation facility has the following disadvantages.

First, there is a problem that it is difficult to secure flexibility in the installation work of the ventilation facility. That is, the number of exhaust ducts installed in each house or office may be different from house to house, and therefore, various types of distributors corresponding to the number of exhaust ducts in which the plurality of exhaust ducts are collected must also be manufactured. In addition, since the connection duct for connecting the distributor and the exhaust duct is further added, there is a problem that the installation of the ventilation facility becomes more cumbersome or the economic efficiency is lowered.

Second, in the conventional distributor, the branch pipe connected to the exhaust duct installed in the building is formed integrally with the distributor. Therefore, there is a problem in that the process of connecting the exhaust duct extending in various directions to the branch pipe for connecting the duct of the distributor is difficult.
