TECHNICAL FIELD OF THE INVENTION The present invention relates to a ventilation fan that connects a ventilation pipe to a vent body provided in an outer case and performs ventilation through the ventilation pipe.

TECHNICAL BACKGROUND OF THE INVENTION Conventionally, for example, in a ceiling ventilation fan, an exhaust port body serving as a vent body is provided in a side plate part, and an outer box equipped with an air blower inside is attached to the ceiling space. An exhaust pipe, which is a ventilation pipe, is connected to the exhaust port body, and the indoor air is appropriately discharged to the outside through the exhaust pipe.

Problems with the Background Art In the conventional device described above, if the position of the exhaust port body of the outer box and the exhaust pipe is misaligned, the outer box must be reinstalled and its position adjusted, or the exhaust pipe must be reinstalled. There is no way to adjust the position by using the button, which is troublesome, and the first adjustment does not necessarily match the positions of the two, so there is a problem that the adjustment work requires time and effort. there were.

OBJECTS OF THE INVENTION Accordingly, the present invention provides a ventilation fan in which the vent pipe can be easily connected to the vent body without the troublesome work of attaching and repairing the outer case and the vent pipe.

SUMMARY OF THE INVENTION The present invention provides a method for forming an outlet in a side plate of an outer box, disposing a vent body so as to protrude from the outlet and to be movable within the outlet. This book is characterized in that it is held at an arbitrary position by being clamped to the outlet edge by a backing plate part and a pressing member.

EMBODIMENT OF THE INVENTION A first embodiment of the invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 denotes a ceiling plate in the building, which partitions the interior 2 and the attic 3. Reference numeral 4 denotes an outer ring having an opening at the bottom, and the opening at the bottom serves as a suction opening 5. The outer box 4 is installed in the attic 3 so that the inlet 5 faces the indoor room 2. 6 habe mouse 6

They are arranged horizontally to form 17. 8 is a blower device arranged in the blower chamber 7, which is driven by a drive motor 9.
and a fan 10.

In Figures 1 and 2, 11 is a circular outlet;
This is formed on the side plate portion 4& of the outer box 4. Reference numeral 12 denotes an exhaust port body, which is a vent body, and this has a tapered cylindrical shape whose diameter decreases from one end to the other end, and even at its maximum diameter, the diameter is smaller than the outlet port 11. It is set as follows.

A flange portion 15 extending outward is formed on the periphery of one end (large diameter side end) of the exhaust port body 12, and the flange portion 13 is provided with an elastic body, such as a countersunk washer, as a pressing member. A leaf spring 14 having a shape is screwed to the winding. Further, an annular backing plate portion 15 is screwed to the substantially middle portion of the outer waste portion of the exhaust port body 12 so as to face the flange portion 13 .

In this case, the outer diameters of the leaf spring 14 and the backing plate 15 are set to be larger than the diameter of the outlet 11. The exhaust port body 12 is arranged at the outlet 11 so that the leaf spring 14 and the backing plate 15 face each other with the side plate 4a of the outer box 4 sandwiched between them. 12 is the outlet port 1
1 and is movable within the outlet 11 in the direction along the side plate portion 4&. Furthermore, the leaf spring 14 presses the shoulder edge of the outlet 11 with its spring force (resilient force), and as a result, the original leaf spring 14 and the backing plate 15 cause the outlet 11 to become green. It is holding Iku in its arms, and the exhaust port body 12
is designed to be held in any position, and the outlet 1
jl[l! of the exhaust port body 12 in 1] The portion where the IK is located is closed by the backing plate portion 15. 1
Reference numeral 6 denotes an exhaust pipe as a ventilation pipe, which is attached to the ceiling 3 via a mounting bracket (not shown), and one end of which is connected to the other end (small diameter end) of the exhaust port body 1z. The other end (not shown) is led out to the outside.

Here, in the case of connecting the exhaust pipe 16 and the exhaust port body 12, if the positions of the two are misaligned, k means the exhaust port body 12.
It is only necessary to align the outer box 4 by moving it in an appropriate direction such as up and down, left and right (the dotted chain line in Figure 2 shows one form after the movement). There is no need to repair the exhaust pipe 16 or install or repair the exhaust pipe 16.

In the above configuration, when the drive motor 9 is driven,
Due to the blowing action of the blower device 8), indoor air is injected into the room.5. Blow room 7. The air is exhausted to the outside through the exhaust port body 12 and the exhaust pipe 16, thereby ventilating the room.

According to this embodiment, the following effects can be obtained. ID, the exhaust port body 12 is movable to the side plate 4 of the outer box 4, so when aligning the exhaust port body 12 and the exhaust pipe 16, it is necessary to attach the outer box 4 and the exhaust pipe 16. It is possible to adjust the movement of the exhaust port body 12 and align the two with a simple operation without having to do anything to repair the exhaust port body 1.
2 and the exhaust pipe 16 can be easily connected. or,
Since the exhaust port body 12 is movable within the outlet port 11 and is held by sandwiching the shoulder edge of the outlet port 11 between the plate part 14 and the roaring plate part 15, the exhaust port body 12 can be moved within the outlet port 11. top and bottom,
It can be moved in any direction, such as left or right, and can be held securely in any position after movement. Furthermore, since the plate spring 14 is used as a pressing member, a clamping action can be obtained at all times, and no clamping work 4 is required.
Overall, further effects can be obtained in terms of positioning the exhaust port body 12 and the exhaust pipe 16 and facilitating the connection work.

Next, FIG. 3 shows a second embodiment of the present invention. In the second embodiment, the exhaust port body 12 has a flange having approximately the same outer diameter as the backing plate part 15 instead of the flange part 13. This embodiment differs from the first embodiment in that a plurality of screws 18 are provided as pressing members on the outer layer of the terrange section 17.
Substantially the same effects as in the first embodiment can be obtained.

However, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the spirit of the invention.

The alignment of the two may be exactly the same as the upper and lower sides.

It is possible to provide a ventilation fan that can reliably perform the operation even when the ventilation port body and the ventilation pipe are deviated from each other in any direction, such as left or right, and can thereby greatly improve the workability of connecting the ventilation port body and the ventilation pipe.
