DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter for preventing outside air from entering in a ventilation device.

[0002]

2. Description of the Related Art Conventionally, as this type of ventilator, FIG.
As shown in the figure, the supply / exhaust blower 1 and the heat exchanger 2 are installed inside,
A shutter 6 for opening and closing the air supply port 3 and the air exhaust port 4 on a main body 5 having an air supply port 3 and an exhaust port 4 formed on the back surface thereof, and a main body outer shell 7.
And a mounting plate 9 having a ventilation tube 8 are known (for example, see Japanese Utility Model Application Laid-Open No. 63-116836).

[0003]

In the conventional ventilating apparatus described above, the air supply port 3 and the exhaust port 4 on the back of the main body 5 are provided.
The shutter 6 that opens and closes the air supply port 3 and the exhaust port 4 with a single plate
With the structure that has the opening 10 communicating with the main body 1 and slides the back surface of the main body 1 left and right, there is a problem that the shutter 6 is large, the sliding space of the shutter 6 is required on the main body 1 side, and the ventilation device becomes large. .

The present invention has been made to solve the above-mentioned problems, and has as its object to provide an inexpensive ventilator in which a shutter and a ventilator can be reduced in size.

[0005]

A ventilating apparatus according to the present invention is provided with a ventilation port for forming an air supply or exhaust passage in a main body case, and a sliding shutter for arbitrarily opening and closing the ventilation port. In a ventilator for ventilating indoors and outdoors through an opening, one end of the shutter is connected to the vent, and a first shutter that is freely bendable is connected to the other end of the first shutter. This is a divided configuration of the second shutter and the second shutter.

[0006]

According to the present invention, a ventilation opening for forming an air supply or exhaust passage in the main body case and a sliding shutter for arbitrarily opening and closing the ventilation opening are provided, and the indoor and outdoor ventilation is provided through the ventilation opening. In the ventilating apparatus, one end of the shutter is connected to the ventilation port, and the first shutter is bendable.
And the second shutter connected to the other end of the first shutter, the first shutter and the second shutter are continuously connected in a state where the shutter is slid and the vent is closed. The first shutter is bent and the second shutter is overlapped with the first shutter in a state where the first shutter is provided and the vent is opened.

【Example】

Embodiment 1 FIG. FIGS. 1 to 4 show an embodiment of the present invention. In the drawings, reference numeral 13 denotes a main body constituting a ventilation device 14, which is composed of a main body case and has an air supply port 15 at an upper portion on the indoor side.
An exhaust port (not shown) is provided at the lower part. Although not shown, the main body is connected to a blower unit provided inside and outside of which is provided with a blower for air supply / exhaust and a multi-layer pipe (described later) penetrating a wall (not shown). It has independent supply and exhaust passages. Reference numeral 16 denotes a vent provided on the back of the main body 13 and forms a supply / exhaust passage. Reference numeral 17 denotes a multi-layer tube, which is made of, for example, vinyl chloride and has a partition 18 and is internally partitioned into two layers, and is connected to the vent 16 through a wall. Reference numeral 19 denotes a heat exchanger holder, which is made of, for example, styrofoam and has a bottom and has a communication hole 20 at a position facing the ventilation port 16 and is provided inside the main body 13. Reference numeral 21 denotes a heat exchanger in which a plurality of partition plates (not shown) are stacked via a spacing plate (not shown) so that a primary airflow and a secondary airflow alternately flow between the above layers. Consists of square pillars. Reference numeral 22 denotes a shutter, and 23 denotes a first shutter which forms one of the shutters. The first shutter is provided between the main body 13 and the heat exchanger holder 19, and is made of, for example, a bendable thin film material and has one end provided with the ventilation port. 16. Reference numeral 24 denotes a second shutter which forms the other of the shutter 22 and is made of, for example, a plate material.
Is polymerized to the other end. As shown in FIG. 3, the distance L from the air vent end 25 of the main body 13 which is the mounting portion of the shutter 22 to the right end corner 26 is the lateral dimension A of the second shutter 24 and the opening of the air vent 16. The dimension (A + B) is obtained by adding the dimension B. 27 is a mounting plate for the main body 1
The multi-layer pipe 17 is mounted on the back of the vehicle 3 to connect the multi-layer pipe 17 to the ventilation port 16.

In the ventilator constructed as described above, the multi-layer pipe 1 is operated by operating the air supply / exhaust blower.
The supply / discharge operation is performed via 7. Then, in this case, as shown in FIG. 3B, the shutter 22 opens the ventilation port 16 and the first shutter 23 is bent so as to overlap,
Further, the second shutter 24 is superimposed on the first shutter 23 and covers the inner wall of the main body 13. On the other hand, when the air supply / exhaust air blower is not operated, the first and second shutters 23 and 24 extend in a planar shape and cover the ventilation port 16 as shown in FIG. As described above, a shutter twice as large as the dimension B shown in FIG. 3 was conventionally used to seal the ventilation port 16, but the lateral dimension A of the first shutter 23 and the opening dimension B of the ventilation port 16 And the size of the shutter 22 and the main body 13 can be reduced.

Embodiment 2 FIG. Further, as shown in FIG. 4, the same effect as that of the first embodiment can be obtained by providing the shutter 22 with the escape groove 31 for the main body 13 having the partition plate 30 in the ventilation port 16 for preventing the mixture of supply and exhaust. Is obtained.

[0010]

As described above, according to the present invention, the main body case is provided with the ventilation port for forming the air supply or exhaust passage, and the sliding shutter for arbitrarily opening and closing the ventilation port. In a ventilator for ventilating indoors and outdoors, one end of the shutter is connected to the vent, the first shutter is bendable, and a second shutter is connected to the other end of the first shutter. Since the first shutter is bent during storage when the shutter is not used, a sliding space equivalent to the entire length of the shutter is not required. And cost reduction.
