2. Description of the Related Art A variety of ventilators having the above-mentioned functions have been conventionally provided, and a typical one is a ventilator having an indoor partition plate 6 provided with a large number of vent holes 5 as shown in FIG. A main body 7, a slide plate 9 provided with a ventilation hole 8 in a positional relationship that can be aligned with the ventilation hole 5 of the ventilation device main body 7, and sliding in a state of being substantially in close contact with the indoor-side partition plate 6; The sliding plate 9 is slid via an operation knob 13 provided on the indoor side, comprising an outdoor partition plate 12 having a protruding portion 11 provided so as to cover the vent hole 10 from the upper outdoor side. And a type in which a ventilation path is opened and closed according to a matching relationship between the ventilation hole 8 of the slide plate 9 and the ventilation hole 5 of the ventilation device main body 7, and is used for ventilation between an indoor room and an outdoor room. In a ventilation system, insects and air Etc. is so as not to entering indoors, would also be present, for example stretched filter serving net vents 8 of the slide plate 9.

[0003]

However, the conventional ventilators such as those described above require a large number of components in addition to the ventilator body in order to perform the function of opening and closing the ventilation path. The cost required for manufacturing and assembling the same is extremely high. In particular, there is a problem that it is difficult to obtain high watertightness or airtightness due to the structure of the means for opening and closing the ventilation path using the slide plate as in the above example.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ventilation device which can be manufactured at low cost and has high watertightness and airtightness.

[0005]

A ventilating apparatus according to the present invention, which has been made to solve the above-mentioned problems, has a relay room through which outside air and inside air can flow, and the relay room has an external flow opening which is always open. And an internal circulation port which is opened and closed by a swinging door.

The outside air and the inside air refer to inside and outside air with respect to a certain space, and may be interpreted as indoor air and outdoor air, or may be interpreted as indoor outdoor air and indoor air. In particular, when circulating indoor air and outdoor air, it is desirable to open the outer circulation port at a position deviating from the precipitation orbit. The external flow opening that opens at a position deviating from the precipitation trajectory is, for example, an external flow opening that opens directly below or diagonally downward so that rain or the like falling from the top does not directly enter. A structure having a structure in which the upper part of the outer circulation port is covered by a part of a partition wall of the ventilation device or a relay room.

[0007] In order to obtain the minimum necessary function as a ventilator for closing the entire internal circulation port, it is not necessary to particularly limit the mode of the swing door. However, in order to prevent the swinging door from protruding into the room, it is preferable to open the inside. In order to open and close the inner circulation port with a small number of operations over a wide area in the width direction of the ventilation device, it is necessary to use a horizontal opening parallel to the partition wall. Those that oscillate about an axis are preferred. In addition, in order to facilitate opening and closing operations of the swing door, it is desirable to form a knob or other clues on the swing door. It is desirable to attach a sealing material to the edge of the inner circulation port where the swinging door contacts.

[0008] Further, in the case of disposing it facing outdoors, a swinging door can always be interposed between the outer circulation port and the inner circulation port regardless of whether it is open or closed. That is, it is preferable that the swinging door has a structure in which an inner circulation port is provided above the outer circulation port and the swing door that opens and closes the inner circulation port swings above the support shaft.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a ventilation device according to the present invention will be described with reference to the drawings. The ventilation device shown in FIGS. 1 and 2 is an example of a ventilation device incorporated as a lower frame of a sliding door. This ventilator includes a ventilator body (hereinafter, referred to as a main body) 14 and an swing door 3 integrally formed by extrusion molding from a metal material having high corrosion resistance. The main body 14 includes a holding portion 15 for fixing glass and a sealing material or a door plate at an upper portion, a functional space 16 for mounting a door roller at a lower portion, and an external partition wall 17 opposed to each other in parallel. A relay room 1 sandwiched between inner partition walls 18 through which outside air and inside air can flow, and a bottom wall 19 of the relay room 1
A guide space 20 is formed over the entire width of the main body and communicates with the outside through the outer circulation port 2 formed in a vertical stripe at a constant pitch.

The guide space 20 has a state in which a part of the outer partition wall 17 is recessed to a depth reaching the position of the inner partition wall 18, and the bottom wall 19 of the relay room 1 is provided above the guide space 20.
And the functional space 16 is provided below the guide space 20.
Is present. On the top wall 21 of the relay room 1 and the functional space 16, holding grooves 22, 22 to be screwed with screws used when combined with a vertical frame (not shown) have a C-shaped cross-sectional shape, and A support groove 23 having a C-shaped cross section as a bearing portion of the swing door 3 is formed over the entire width of the main body 14 at an upper portion of the inner partition wall 18 in the relay room 1. Is formed.

The swing door 3 has a shaft portion 24 serving as a support shaft having a partially cut-out circular cross-sectional shape and a flat lid portion 25 integrated with each other. By positioning the shaft portion 24 into the support groove 23 from the longitudinal end thereof, the swing door 3 can swing with respect to the main body 14 inside the relay chamber 1. The swing door 3
A sealing material 26 is fitted to the edge of the inner flow opening 4 and functions to increase the airtightness when the sealing member 26 is closed.
In addition, a clue is formed at the center of the lid 25 by fitting the cap 27 having an appropriate depth from the outside into the through hole, so that the swing door 3 can be easily opened and closed.

In addition to the above-described embodiment, the ventilating apparatus according to the present invention has a lid 25 itself formed into a shape having clues for opening and closing as shown in FIG. 3, and an internal circulation as shown in FIGS. 4 and 5. The swing door 3 that opens and closes the mouth swings above the shaft portion 24 serving as a support shaft, so that the swing door 3 always swings between the outer circulation port 2 and the inner circulation port 4 even when the door is open. The outside air can be efficiently directed to the back surface of the swing door 3 by interposing the door 3 to prevent entry of rain or the like, and by adjusting the inclination of the walls 19 and 21 constituting the guide space 20 as shown in FIG. There is also a structure having a structure for guiding well and automatically closing the internal circulation port 4 in a strong wind.
Further, when ventilating a specific indoor room, the external circulation port 2 does not need to be opened at a position deviating from the precipitation trajectory as in the example shown above, so that the external circulation port 2 is provided with the external partition wall 17. The guide space 20 provided in the above-described example is not required (see FIG. 7).

In the case where a structure is employed in which the swing door 3 swings above the shaft portion 24 serving as a support shaft in the relay chamber 1, the lid 25 of the swing door 3 causes the inside of the relay chamber 1 to move. Since the ventilation path may be closed, the shape of the bottom wall 19 of the relay room 1 is devised as shown in FIG. 4 or the movement of the swing door 3 is controlled by separately providing a stop piece 28 as shown in FIG. Some restriction is needed. Further, in order to stabilize the posture of the swinging door 3 at the time of opening and closing, there is a case where an elastic material 30 provided with a notch portion 29 with which the edge of the swinging door 3 is hooked is loaded into the relay chamber 1.
In order to prevent insects and dust from entering, a net covering the outer circulation port 2 may be attached.

Although the ventilation device according to the present invention has been described above as a ventilation device incorporated as a lower frame of a sliding door, a large number of structures can be incorporated in addition to the sliding door, such as doors, walls, windows for killing, and the like. And can be appropriately incorporated as a frame material constituting them. Therefore, the holding unit 15 and the functional space 16 are not always arranged vertically above and below the relay room 1 in the entire ventilation device. And the function space 16 may be reversed, and a structure having completely different functions from the above-described ventilation device is employed above and below the relay room 1 in the entire ventilation device depending on the structure to be incorporated. In some cases.

[0015]

As described above, the use of the ventilating apparatus according to the present invention requires only a small number of components for performing the function of opening and closing the ventilation path, thereby reducing the cost of manufacturing these components and assembling them. In addition, by opening and closing the internal flow opening with the swinging door, the structure in which the sealing material is less consumed when the sealing material is provided than in the case of opening and closing by the slide plate, is further provided.
By providing the outer circulation port at a position deviating from the precipitation orbit, it is possible to prevent direct intrusion of rain and the like, and to provide a highly watertight and airtight ventilation device.

In addition, an internal communication port is provided above the external communication port, and a swinging door for opening and closing the internal communication port is structured to swing above the support shaft, so that the opening door is opened. A swinging door can always be interposed between the outer circulation port and the inner circulation port regardless of whether it is closed or closed. Thus, in the case of disposition facing the outdoors, it is possible to more reliably prevent intrusion of rain and the like at the time of opening, and to prevent erroneous opening due to strong wind and the like at the time of closing. .
