Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning ventilator having a ventilation pipe for partitioning the inside of the pipe into an intake side and an exhaust side for intake and exhaust, and more particularly to an air conditioning ventilator capable of relaxing restrictions on the installation location of the air conditioning ventilator. It is about.

[0002]

2. Description of the Related Art An air-conditioning ventilation fan that introduces outdoor air into a room and discharges the indoor air at the same time has an intake / exhaust passage formed by a single pipe as shown in FIG. 6 (one-pipe simultaneous intake / exhaust type).
It has been known. As shown in the figure, the intake / exhaust pipe 2 extending from the air-conditioning ventilation fan main body 1 to the outside is divided into the intake side and the exhaust side into one pipe in the cross-sectional direction to intake and exhaust.

[0003]

By the way, since the ventilation pipe 2 is simply extended from the air conditioning ventilation fan 1 as described above, the installation of the air conditioning ventilation fan 1 is limited to the outer wall in the conventional case. There was a problem that place restrictions became large. When the ventilation pipe 2 is embedded in the wall as in Japanese Patent Application No. 4-317597, the ventilation pipe 2 is located directly behind the air conditioning fan because of the relationship between the installation height on the indoor side and the external wall structure of the building. It may not be possible to penetrate straight through the outer wall.

On the other hand, the drain is also discharged to the outside through the exhaust side of the ventilation pipe 2, and when it is installed on the sweep window, there is a possibility that the passerby is drained. Further, when the air-conditioning ventilation fan 1 is installed in parallel with the air conditioner, the drain pipe of the air conditioner is arranged in a separate system, so that it is necessary to secure a piping space and perform construction work separately.

The present invention was devised to effectively solve the above problems.

An object of the present invention is to provide an air conditioning ventilator capable of alleviating restrictions on the installation location of the air conditioning ventilator and treating drains indoors.

[0007]

According to the present invention, there is provided an air conditioning ventilator having a ventilation pipe for partitioning the inside of the pipe into an intake side and an exhaust side for intake and exhaust, and the ventilation pipe is longitudinally connected to the air conditioning ventilator side. A partition that divides the ventilation pipes into the outdoor side and connects these ventilation pipes with a connecting box, and divides them into an intake passage that connects the intake sides of the divided ventilation pipes and an exhaust passage that connects the exhaust sides to each other. A wall is formed and a drain pipe is connected to the bottom of the connection box on the exhaust side.

Further, the connecting box is formed with a connection port on one side wall surface thereof, which is divided into an intake side and an exhaust side by the partition wall for connecting the air conditioning ventilation fan side ventilation pipe. On the side wall surface adjacent to the one side wall surface or on the side wall surface facing the one side wall surface, a connection port partitioned by the partition wall into an intake side and an exhaust side is formed for connecting the outdoor side ventilation pipe. Further, a connection port for connecting the drain pipe of the air conditioner is formed on the exhaust side of the connection box partitioned by the partition wall.

[0009]

[Operation] If the ventilation pipe on the air conditioning ventilation fan side and the ventilation pipe on the outdoor side are connected by the connecting box in this way, the intake / exhaust passage can be bent through the connecting box according to the installation situation. It is possible to ease restrictions on the installation location of air conditioning ventilation fans.

Further, the drain is collected indoors through the drain pipe connected to the connecting box, and when the air conditioning ventilation fan is installed in parallel with the air conditioner, if the drain pipe of the air conditioner is connected to the connecting box, common drainage will be obtained. Draining can be done through the route.

[0011]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 5 shows an example in which an air conditioning ventilation fan 11 for ventilating indoor air is installed side by side on an indoor unit 12 of an air conditioner.

As shown in FIG. 1, the air conditioning ventilation fan 11 has
The air-conditioning ventilation fan-side ventilation pipe 13 and the outdoor-side ventilation pipe 14 are formed by dividing the ventilation pipe for dividing the circular cross section of the pipe into the intake side and the exhaust side into the left and right sides and dividing the ventilation pipe into two in the longitudinal direction. These ventilation pipes 13 and 14 are connected to each other via a connecting box 15 having six faces. Connection box 15
The inside is partitioned by a partition wall 16 into an intake side and an exhaust side. An intake passage 17 is formed on the intake side to connect the intake sides of both ventilation pipes 13 and 14 to each other. An exhaust passage 18 connecting the exhaust sides of the ventilation pipes 13 and 14 is formed.

In the illustrated example, one side wall surface 21 formed in the connecting box 15 has a circular cross-section connection port which is divided into an intake side and an exhaust side by a partition wall 16 for connecting the air conditioning ventilation fan side ventilation pipe 13. 22 is formed, and the other side wall surface 23 adjacent to the one side wall surface 21 and facing the outdoor side is partitioned by the partition wall 16 to the left and right sides to connect the outdoor side ventilation pipe 14. A connection port 24 having a circular cross section is formed.

That is, in order to form a continuous intake / exhaust passage that is divided into the intake side and the exhaust side and passes through the connecting box 15, the partition wall 16 is bent into a substantially L-shaped cross section so that the inside of the connecting box 15 is closed. In addition to partitioning the intake side and the exhaust side, the partition wall 16
Both ends of the partition wall 13 for partitioning the air conditioning ventilation fan side ventilation pipe 13 and the outdoor side ventilation pipe 14 into an intake side and an exhaust side.
The ends of a and 14a are abutted on the same plane.

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

Therefore, both intake and exhaust air passing through the ventilation pipes 13 and 14 are carried out in the opposite directions via the connecting box 15,
The intake / exhaust air passes through the partition wall 16 in the connecting box 15 without being mixed. By connecting the ventilation pipes 13 and 14 with the connecting box in this manner, the intake and exhaust passages can be bent at a right angle through the connecting box 15, so that the air conditioning ventilation fan 11 can be installed on a partition wall other than the outer wall. And
The restrictions on the installation location can be greatly improved. In addition, the connection port 24 of the outdoor side ventilation pipe 14 is provided on the left and right opposing side wall surfaces 2
Provided on 3, 31 and take necessary openings by punching,
Moreover, if the partition wall 16 is made detachable so that the left and right sides can be interchanged, it is possible to cope with the manufacturing models without increasing them.

Further, since the drain can be treated on the exhaust side of the connecting box 15 without being discharged to the outside through the drain pipe 26, even if the air-conditioning ventilation fan 11 is installed on the sweep window, the drain will not reach the passerby. It can be prevented. Further, when the air conditioning ventilation fan 11 is installed in parallel with the air conditioner 12, the connecting box 1
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 unnecessary.

FIG. 2 shows the outdoor side connection port 24 in a lowered 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 the restriction on the building structure. Further, in the past, in order to perform drainage, the ventilation pipe 2 had to be made to have a downward slope, but in the present invention, since drainage is performed by the connecting box 15, the connection port on the outdoor side does not have to worry about this point. It is also possible to raise 24 to the upper position, contrary to this embodiment.

3 and 4, the outdoor side ventilation pipe 14 is connected to the side wall surface 23 of the connecting box 15 facing the outdoor side, and the air conditioning ventilation fan side ventilation pipe 13 is connected to the side wall surface 31 facing the side wall surface 23. It is connected.

In FIG. 3, the ventilation pipes 13 and 14 connected to the connecting box 15 are connected at the same height, whereas
As shown in FIG. 4, if the air conditioning ventilation fan side ventilation pipe 13 is connected to the upper stage and the outdoor side ventilation pipe 14 is connected to the lower stage, the ventilation pipe is straight to the outer wall 32 directly behind the air conditioning ventilation fan 11 due to the structure of the building outer wall. It can be used when it cannot penetrate the Reference numeral 33 is a makeup grill, and 34 is a makeup cover.
