However, in the conventional simultaneous supply / exhaust type ventilation port for two pipes, the supply port and the exhaust port are generally provided side by side, and the supply port and the exhaust port are provided. In order to prevent a short circuit between the air supply and the exhaust, it is necessary to provide them separately. As a result, there is a problem that the ventilation opening and its weather cover become large. In addition, since the side-by-side positions of the air supply and exhaust ports are fixed in relation to the shape of the weather cover, depending on the relative position between the ventilation device and the air vent, the air supply pipe or the exhaust pipe may be bent in multiple steps and piping I needed to.

In the case of using a double pipe, there is a problem that a bent double pipe is expensive and it is difficult to construct a bent portion.

The present invention has been made to solve the above-mentioned problem, and an object of the invention is to provide a simple and inexpensive piping for a ventilation system and a compact simultaneous supply / exhaust ventilation system. It is intended to provide a mouth.

The base 5 has a square cross section in the embodiment, and is formed in a cylindrical shape having an outer opening 6 on one side and an inner opening 7 on the opposite side.

The air supply opening frame 10 is formed in a rectangular box shape with one surface opened, and each peripheral wall is provided with an opening 12. Further, a cylindrical socket 14 for connecting an exhaust pipe 38 is provided in the bottom portion 13 at a predetermined position eccentric to the center of gravity C so as to penetrate the bottom portion 13. . Reference numeral 15 denotes a flange for attaching to the base 5.

The weather cover 20 has a square cross section that can be fitted on the peripheral wall of the air supply port frame 10, and an exhaust passage 22 is formed between the base end 21 and the exhaust port 23 at the outer end. . An air supply port 24 that can communicate with the opening 12 of the air supply port frame 10 is provided at a lower portion of the base end section 21. A flange 25 is provided for attachment to 5.

As described above, the air supply port frame 10 and the abutment plate 30 are rotated and attached to the base frame 5, so that the parallel air supply pipes 36 and the exhaust pipes 38 can be connected with the minimum number of bends.

No matter where the socket 14 of the air supply port frame 10 is rotated, the air supply chamber 35 is opened and the air supply port 2 is opened.
The communication with the outside air is possible via 4. Since the outside air is once introduced into the air supply chamber 35 and then guided to the air supply pipe 36, it is possible to prevent the supply air pressure from being directly influenced by the wind pressure of the outside air.

Further, since the exhaust pipe 38 penetrates through the air supply chamber 35 and communicates with the inside of the weather cover 20, the bottom portion 13 of the air supply port frame 10 becomes a wall separating the air supply path and the exhaust path. In addition, the air supply and the exhaust do not mix in the simultaneous air supply / exhaust type ventilation port 1. Further, since the air supply port 24 on the lower surface of the base end 21 of the weather cover 20 is separated from the exhaust port 23 on the front end, a short circuit between the air supply and exhaust is prevented.

It should be noted that the present invention is not limited to the above description and examples of the drawings, and the embodiments thereof can be changed without departing from the technical idea of the present invention. For example, the base frame and the air supply opening frame may be cylindrical, and the plate may be correspondingly circular.

Also, a heat exchanger may be installed in the air supply chamber to adjust the temperature of the air supplied indoors.

[0030]

[Effect of the Invention] The simultaneous supply / exhaust type ventilation port of the invention is configured as described above, so that by rotating the supply port frame and the abutment plate, two air supply pipes and an exhaust pipe are provided between the ventilation apparatus. And the air supply pipe and the exhaust pipe can be connected by piping with the minimum number of bendings, so that the piping work can be performed simply and inexpensively. As a result, it is possible to easily select the installation location of the simultaneous supply / exhaust ventilation port.

Further, since the outside air is once introduced into the air supply chamber and then guided to the air supply pipe, the supply pressure does not depend on the wind pressure of the outside air.

Further, since the air supply path and the exhaust path are separated by the air supply port frame, the air supply pipe and the exhaust pipe can be provided close to each other. Can be prevented from being mixed, and the ventilation port can be formed compact. In addition, since the air supply port on the lower surface of the base end portion of the weather cover and the exhaust port on the distal end portion are separated from each other, there is an effect that a short path of air supply and exhaust can be prevented.
