DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning ventilation fan having ventilation pipes for dividing and piping the inside of a pipe into an intake side and an exhaust side and sucking and exhausting the air. It is about.

[0002]

2. Description of the Related Art As shown in FIG. 6, an air-conditioning ventilator for introducing outdoor air into a room and simultaneously discharging indoor air has an intake / exhaust passage formed by a single pipe (one-pipe simultaneous intake / exhaust type).
It has been known. As shown in the figure, an intake / exhaust pipe 2 extending from the air-conditioning ventilator main body 1 to the outside is configured so that one pipe is partitioned into an intake side and an exhaust side in the cross-sectional direction to the left and right to intake and exhaust.

[0003]

By the way, since the ventilation pipe 2 is simply extended from the air-conditioning ventilation fan 1, the installation of the air-conditioning ventilation fan 1 is conventionally limited to the outer wall. There was a problem that location restrictions became large. When the ventilation pipe 2 is buried in the wall as in Japanese Patent Application No. 4-317597, the ventilation pipe 2 is placed directly behind the air-conditioning ventilation fan due to the relationship between the installation height on the indoor side and the outer wall structure of the building. May not be able to penetrate the outer wall straight.

[0004] On the other hand, the drain is also discharged outside through the exhaust side of the ventilation pipe 2, and when installed on the discharge window, there is a possibility that the pedestrian may be drained. In addition, when the air conditioner / ventilation fan 1 is installed side by side with the air conditioner, since the drain pipe of the air conditioner is provided in a separate system, it is necessary to secure a piping space and separately perform construction work.

The present invention has been made to effectively solve the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air-conditioning ventilator capable of alleviating the restrictions on the installation place of the air-conditioning ventilator and treating the drain indoors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 5 shows an example in which an air-conditioning ventilation fan 11 for ventilating room air is juxtaposed on the side of an indoor unit 12 of an air conditioner.

This air-conditioning ventilation fan 11 is, as shown in FIG.
An air-conditioning ventilation fan-side ventilation pipe 13 and an outdoor-side ventilation pipe 14, which are formed by dividing a ventilation pipe that divides a circular cross section of the pipe into an intake side and an exhaust side on the left and right and sucks and exhausts the air in two parts in the longitudinal direction, These ventilation pipes 13 and 14 are connected to each other via a connection box 15 having six surfaces. Junction box 15
The inside is partitioned by a partition wall 16 into an intake side and an exhaust side. An intake path 17 is formed on the intake side to connect the intake sides of both ventilation pipes 13 and 14 to each other, and both sides are formed on the exhaust side. An exhaust passage 18 connecting the exhaust sides of the ventilation pipes 13 and 14 to each other is formed.

In the illustrated example, a connection port having a circular cross section divided into an intake side and an exhaust side by a partition wall 16 for connecting an air conditioning ventilation fan side ventilation pipe 13 to one side wall surface 21 formed in the connection box 15. The other side wall surface 23 adjacent to the one side wall surface 21 and facing the outdoor side is partitioned into an intake side and an exhaust side left and right by a partition wall 16 for connecting the outdoor side ventilation pipe 14. A connection port 24 having a circular cross section is formed.

That is, the partition wall 16 is bent into a substantially L-shaped cross section so as to form a continuous intake / exhaust passage which is partitioned into the intake side and the exhaust side via the connection box 15, and is formed inside the connection box 15. In addition to partitioning between the intake side and the exhaust side, the partition 16
Both ends of the partition wall 13 partition the air conditioning ventilation fan side ventilation pipe 13 and the outdoor side ventilation pipe 14 into an intake side and an exhaust side.
a and 14a butted against each other on the same plane.

A bottom wall 25 is provided on the exhaust side of the connection box 16.
A connection port 27 for connecting a drain pipe 26 is formed on the side wall 21, and a connection port 29 for connecting a drain pipe 28 of the air conditioner is formed on the side wall surface 21.

Therefore, the intake and exhaust air passing through the ventilation pipes 13 and 14 are both performed through the connection box 15 in opposite directions.
In the connection box 15, the intake and exhaust air passes through the partition wall 16 without mixing. When the ventilation pipes 13 and 14 are connected by the connection box 15 in this manner, the intake / exhaust passage can be bent at a right angle through the connection box 15, and thus the air-conditioning ventilation fan 1 can be bent.
1 can be installed on a partition wall other than the outer wall, and the restriction on the installation location can be greatly improved. Further, the connection port 24 of the outdoor ventilation pipe 14 is provided with left and right side walls 23 and 31 facing each other, a necessary opening is formed by punching or the like, and the partition wall 16 is detachable so that the left and right can be switched. Change the connection position of the ventilation piping.
It can be used without increasing the number of production models, even at installation positions that are severely restricted .

Further, on the exhaust side of the connection box 15, the drain can be treated without being discharged to the outside through the drain pipe 26, so that even if the air-conditioning ventilation fan 11 is installed on the discharge window, the drain will not hit a pedestrian. Can be prevented. Furthermore, when the air-conditioning ventilation fan 11 is installed in parallel with the air-conditioner 12,
5, the drain on the air conditioner side can also be treated by the common drainage system via the drain pipe 26, so that the space for the drain pipe of the air conditioner and the construction work are not required.

FIG. 2 shows the outdoor connection port 24 in a lower position. By lowering the connection port 24, the position of the ventilation pipe defined by the height of the air-conditioning ventilation fan 11 can be lowered, and it is possible to cope with restrictions on the building structure. Conventionally, the ventilation pipe 2 had to be downgraded in order to drain the water. However, in the present invention, since the drainage is performed in the connection box 15, the connection port on the outdoor side does not matter. It is also possible to raise 24 to the upper position contrary to this embodiment.

FIGS. 3 and 4 show that an outdoor ventilation pipe 14 is connected to a side wall surface 23 facing the outdoor side of the junction box 15 and an air conditioning ventilation fan side ventilation pipe 13 is connected to a side wall surface 31 facing the side wall surface 23. Connected.

FIG. 3 shows that the ventilation pipes 13 and 14 connected to the connection box 15 are connected at the same height.
As shown in FIG. 4, if the ventilation pipe 13 for the air-conditioning ventilation fan is connected to the upper stage and the piping 14 for the outdoor ventilation is connected to the lower stage, the ventilation pipe is straightened to the outer wall 32 right behind the air-conditioning ventilation fan 11 on the building outer wall structure. Can be handled when it cannot penetrate through In addition, 33 is a makeup grill and 34 is a makeup cover.
