Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a duct ventilation fan that ventilates a room through a duct communicating with the room and the outdoors.

Conventional technology Traditionally, most houses were single-family houses, and many of the single-family houses were also made of wood. In this wooden house, the walls were made of wood, the ceiling was also made of soft materials, and the attic space was wide, so ventilation inlets were installed on the walls and ceiling of the attic area. There is a wide range of areas where ventilation and exhaust ports can be installed, and the duct ventilation fan can be installed in any location that will not affect the performance of the fan.

For this reason, conventional duct ventilation fans were installed as shown in Figure 3.

That is, a box-shaped frame 101 with a built-in fan 100 is installed on a ceiling with ample space, and a suction adapter 102 provided on one side of the box-shaped frame 101 is installed on a ceiling with sufficient space.
The suction port 105 formed in the air blower 100 is connected to the suction port 105 formed in the air blower 100 through the suction duct 103, thereby communicating the indoor space with the suction port of the blower 100. At this time, since the attic space is wide, the opening position of the suction port 105 and the piping of the suction duct 103 can be arbitrarily determined in consideration of workability, performance of the duct ventilation fan, etc.

Then, the exhaust adapter IQ6 provided on the other side opposite to the one side of the frame 101 is connected to the exhaust port 109 formed on the outer wall 10 through the exhaust duct 107, and the outlet of the blower 100 is connected. It communicates with the outdoors. The opening position of the exhaust port 109 and the piping of the exhaust duct 107 can be arbitrarily determined as described above.

When the duct ventilation fan in the configuration mentioned above is operated, indoor air is sucked in from the suction port 105 by the blower ioo, sent through the suction duct 103 from the suction adapter 102 into the frame 101, and exhausted from the exhaust adapter 106. The air was exhausted to the outside through a duct 107 and from an outlet 109 formed in an outer wall 108.Problems to be Solved by the InventionIn recent years, due to the rise in land prices, housing has become more popular than detached houses. are on the rise, and high airtightness is required, and walls and ceilings are being replaced with hard materials such as concrete, and the locations for installing intake and exhaust ports for ventilation are becoming limited. The height of the attic has become lower, and the number of obstacles in the attic has increased. As a result, it was no longer easy to install ducts, and construction work had to be done by using soft ducts and bending them at large angles to avoid obstacles.
The ventilation resistance in the ducts increased, and the necessary amount of ventilation could not be obtained.

The present invention solves these problems, and even if the locations of the inlet and exhaust ports provided on the ceiling or outer wall for ventilation are limited, or even if there are obstacles in the ceiling, the ventilation fan can be used. The purpose is to enable easy duct piping without degrading performance.

Means for Solving the Problem In order to solve this problem, the present invention provides a bottomed cylindrical first
Of the two second frames, the first frame has a built-in blower, a suction adapter is provided on the side to communicate the inside with the suction duct, and the side of the second frame has the inside and the exhaust duct connected. A duct ventilation fan is constructed by providing an exhaust adapter for communicating with the first frame and the second frame, and arbitrarily selecting mutual positions in the circumferential direction of the first frame and the second frame, and fixing the openings against each other. It is.

Effect With this structure, when installing a duct ventilation fan and piping the duct, the duct ventilation fan itself must be placed in a position where the duct can reach each of the suction and exhaust ports provided on the ceiling and exterior wall without bending as much as possible. , the first frame is fixed with the suction adapter facing the suction port on the ceiling surface, and the second frame is fixed to the first frame with the exhaust adapter facing the exhaust port on the outer wall. Then, the suction and exhaust ducts are connected to the suction and exhaust adapters to complete the process.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, an embodiment of the present invention will be explained based on a button in FIG. 1 and a button in FIG.

The frame of the main body of the exchange S (M) is made up of two bottomed cylindrical frames A1 and frame B2, whose open ends are butted against each other and fixed.The frame A1 has a built-in blower 3, and the inside and the suction are connected to the side. A suction adapter 6 is provided to communicate with the opening duct 4, and a flange A is bent outward at the opening end.
There are 6.

The frame B2 is provided with an exhaust adapter 8 on its side surface that communicates the inside with the exhaust duct 7, and is provided with a 7-lunge B9 bent outward at its open end.

Frame A1 and frame B2 are provided with a plurality of screw holes at the same intervals in their respective flanges AS and B9, and the direction is adjusted by shifting the distance between adjacent screw holes, that is, the position of each by 1 bis. can do.

The installation work of the above-mentioned box or duct ventilation fan in an apartment complex or a high-rise building will be explained below.

In these buildings, there are only a limited number of locations where ventilation inlets and exhaust vents can be installed;
One position is selected for each of the suction port 11 provided in the outer wall 12 and the exhaust port 13 provided in the outer wall 12, where the duct can reach in a substantially straight line without being obstructed by obstacles on the way. Set this position as the installation position of the ventilation fan body.
is fixed to the ceiling with the suction adapter 6 facing the suction port 11. Next, attach frame B2 to exhaust adapter 8.
so that it faces the exhaust port 13, and then turn the flange A at that position.
s, and fix B9 with screws 14. Then, connect the suction adapter 6 and the suction port 11 with the suction duct 4, and connect the exhaust adapter 8 with the suction duct 4.
The construction is completed by connecting the exhaust port 13 and the exhaust port 13 with the exhaust duct 7.

As mentioned above, the installation work of the duct ventilation fan is carried out on frame A1.
, the mutual positional relationship of the frame B2, the flange As,
Adjust in 1 pitch increments of the screw size of B9, and tighten the suction duct 4.
Since the exhaust duct 7 and the exhaust duct 7 can be arranged in a substantially straight line, the work is easy and the performance of the ventilation fan is not deteriorated.

Effect of Enrichment As is clear from the explanation of the examples above, according to this research, there are limited locations where ventilation inlets and exhaust ports can be installed on the ceiling and outside walls. Even if there are many obstacles behind the duct that could interfere with the duct piping, you can adjust the mutual positions of the two frames and select the installation position for the ventilation fan body that allows piping without bending the duct. , it is possible to easily install duct piping without reducing the performance of the ventilation fan.
