Abstract

PURPOSE:To minimize the size of the main body of a ventilating device having a slide type shutter. CONSTITUTION:A shutter 22, which shuts a ventilating port 16 at the back surface of a main body 13, is formed of a first shutter 23, whose one end is connected to the ventilating port 16 and which is bent freely, and a plate type second shutter 24, connected to the other end of the first shutter 23. The shutter is stored while being bent when the shutter is not used and, therefore, the slide space of the shutter is reduced and the size of the main body of the title device can be reduced.

Description

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 intrusion in a ventilation device.

[0002]

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

[0003]

In the conventional ventilation device as described above, the air supply port 3 and the exhaust port 4 on the back surface of the main body 5 are provided.
The shutter 6 that opens and closes the air intake port 3 and the exhaust port 4 is a single plate.
There is a problem that the shutter 6 is large due to the structure in which the rear surface of the main body 1 is slid to the left and right, and the slide 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 problems, and an object of the present invention is to obtain an inexpensive ventilation device in which the shutter and the ventilation device can be miniaturized.

[0005]

A ventilator according to the present invention is provided with a vent hole for forming an air supply or exhaust passage in a main body case, and a slide type shutter for arbitrarily opening and closing the vent hole. In a ventilator that ventilates indoors and outdoors through a mouth, one end of the shutter is connected to the vent, and the first shutter is made bendable and the other end of the first shutter is connected. The second shutter is divided from the second shutter.

[0006]

According to the present invention, the main body case is provided with a vent for forming an air supply or exhaust passage and a slide type shutter for arbitrarily opening and closing the vent, and ventilation for indoor and outdoor ventilation is provided through the vent. In the ventilator for performing the above, the shutter has a first end that is connected to the ventilation port and is bendable.
The second shutter connected to the other end of the first shutter and the second shutter are separated from each other, so that the first shutter and the second shutter are connected in the state in which the ventilation port is closed by sliding. 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 ventilation port is opened.

【Example】

Example 1. 1 to 4 are views showing an embodiment of the present invention, in which reference numeral 13 is a main body which constitutes a ventilation device 14, which is composed of a main body case and is provided with an air supply port 15 at the upper part on the indoor side.
An exhaust port (not shown) is provided at the bottom. Although not shown, the main body is connected to a blower unit provided inside the air-conditioner and provided outside by a multi-layer pipe (described later) that penetrates a wall (not shown), and is connected to each other. It has independent supply and exhaust passages. Reference numeral 16 denotes a vent hole provided on the back surface of the main body 13 to form a supply / exhaust passage. Reference numeral 17 denotes a multi-layer tube, which is made of, for example, vinyl chloride, has a partition wall 18 and is divided into two layers inside, and is connected to the vent hole 16 by penetrating a wall body. Reference numeral 19 denotes a heat exchanger holder, which is made of, for example, styrofoam, has a bottomed shape, and a communication hole 20 is provided at a position facing the vent hole 16 and is internally provided in the main body 13. Reference numeral 21 denotes a heat exchanger, which is configured by stacking a plurality of partition plates (not shown) via a spacing plate (not shown) so that the primary air flow and the secondary air flow alternately flow between the layers. It consists of a square pillar. Reference numeral 22 is a shutter, and 23 is a first shutter that forms one of the shutters, and 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 one end thereof is the vent hole. It is fixed to 16. A second shutter 24 forms the other of the shutters 22 and is made of, for example, a plate material and has the first shutter 23.
Is polymer-bonded to the other end. As shown in FIG. 3, the distance L from the vent end portion 25 of the main body 13 which is the mounting portion of the shutter 22 to the right end corner portion 26 is determined by the lateral dimension A of the second shutter 24 and the opening of the vent opening 16. It becomes the dimension (A + B) which is obtained by adding the dimension B. 27 is a mounting plate, which is the main body 1
3 is attached to the back surface and connects the multi-layer pipe 17 to the vent 16.

In the ventilator constructed as described above, the multi-layer pipe 1 is operated by operating the air supply / exhaust blower.
Feeding / discharging action is performed via 7. Then, in this case, as shown in FIG. 3B, the shutter 22 opens the vent hole 16 and the first shutter 23 is bent so as to overlap,
Further, the second shutter 24 is overlapped with the first shutter 23 and covers the inner wall of the main body 13. On the other hand, when the air supply / exhaust blower is not operated, the first and second shutters 23 and 24 extend in a plane and close the ventilation port 16 as shown in FIG. As described above, in order to seal the ventilation hole 16, a shutter having twice the size of B shown in FIG. 3 has been conventionally used, but the lateral dimension A of the first shutter 23 and the opening dimension B of the ventilation hole 16 are different from each other. Therefore, the shutter 22 and the main body 13 can be downsized.

Example 2. Further, as shown in FIG. 4, with respect to the main body 13 having the partition plate 30 for preventing the mixed flow of the supply / exhaust air in the vent hole 16, by providing the escape groove 31 in the shutter 22, the same effect as that of the above-described first embodiment. Is obtained.

[0010]

As described above, according to the present invention, the main body case is provided with the vent hole for forming the air supply or exhaust passage, and the slide type shutter for arbitrarily opening and closing the vent hole. In a ventilator for indoor and outdoor ventilation, the shutter has a first shutter that is connected to the ventilation port at one end and is bendable, and a second shutter that is connected to the other end of the first shutter. Since the first shutter is bent when it is stored when the shutter is not used, there is no need for a slide space equivalent to the entire length of the shutter, and the main body case and the shutter are small in size. And cost reduction.
