Description

    The device of the present invention relates to a ventilation device for natural ventilation provided in a vertical part or vertical frame such as a fitting window or a general opening / closing window.

    The simplest method used to ventilate is a natural ventilation method that opens and closes windows and shojis to replace room air and outside air. However, windows in high-rise buildings are stronger than the ground. For this reason, there are many cases where the windows cannot be opened and closed, and most of them adopt a centralized system using building air conditioning. The structure that prevents the opening and closing of windows has evolved, and recently there has been an increase in buildings that appear to be composed entirely of glass when viewed from a distance, but the air conditioning of this centralized system has insufficient ventilation. The indoor air is apt to be clean. For this reason, various natural ventilation methods have been devised, using a natural ventilator (see Patent Document 1) or an unsightly air vent with a ventilation opening in the outer wall of the building, a wind tunnel that connects the inside and outside of the building, and an air volume adjustment valve in the wind tunnel A device for ventilating a room (see Patent Document 2) or a ventilation device (see Patent Document 3) that makes it easy to ventilate by using a normal shape of the eye has been provided.

    However, in Patent Document 1, it is necessary to previously form an air inlet / outlet of a wind tunnel communicating with the inside and outside of a sash or curtain wall in advance, which is a custom-made product. There is a problem in that a pre-processing for inserting a cylinder is required in advance by inserting a cylinder into an invisible part to form a ventilation passage instead of using the whole part of In FIG. 1 of Patent Document 1, the indoor blowing is the floor plate opening, and in both Patent Documents 2 and 3, the opening of the indoor blowing is directed toward the ceiling, and dust generated indoors. There is a disadvantage that the deposits are easily deposited and the opening is easily blocked. The present invention has been provided for the purpose of solving such disadvantages.

The present invention has solved the inconvenience by paying attention to the vertical part or the vertical frame from the idea that dust does not accumulate if the opening of the ventilator is made vertical, and refers to the internal structure of the vertical part or the vertical frame. That is, the present invention has a ventilation structure in which the inside of the vertical part or the vertical frame part communicates the outdoor side and the indoor side, and the ventilation adjustment is performed between the first opening part and the second opening part on the indoor side of the vertical part or the vertical frame part. A ventilation amount adjusting means for automatically adjusting the ventilation amount by using the wind pressure of the ventilation from the inside and outside is provided in the ventilation adjusting chamber, and the ventilation amount adjusting means is composed of parts of the same shape. A ventilation amount adjustment plate is suspended freely by a pair of hinge fittings, and when this ventilation amount adjustment plate comes into contact with one of the first opening and the second opening, the periphery of the opening is A sealing member is provided on either the opening peripheral surface of the first opening and the second opening on the side of the ventilation adjustment chamber or both the front and back peripheral surfaces of the ventilation amount adjustment plate so that the surface is sealed. The ventilation amount adjusting plate is provided in the first opening on the ventilation plate provided outside the second opening. It is natural ventilation apparatus according to claim in which means for close tightly has a forced operation can function manually aeration provided.

    The air flow adjustment means here refers to returning the air flow adjustment plate in the air flow adjustment chamber to a fixed position when the outdoor air flow rate from the outside is below a certain amount, and when the air flow adjustment plate is above a certain amount, the air flow adjustment plate flows into the outside air. It is a method of moving in the opening closing direction by that amount according to the amount. For example, it is possible to hang the air flow adjustment plate swingably in the opening sealing direction using a hinge fitting, And an air flow adjustment plate may be provided with an inclined rail or a groove on one side and a groove or an inclined rail on the other side, and the air flow adjustment plate may be placed so as to be swingable in the opening sealing direction. .

    Further, the ventilation shape on the indoor side in the vertical part or the vertical frame may be one-sided or two-sided blowing, and the natural ventilation device may be installed in a plurality of places as needed instead of one. Here, the vertical part, the vertical frame and each part of the window are originally given names, and the vertical frame between the window and the window is the vertical part, and the vertical frame part is at both ends of the window. In the invention, since both are considered to be substantially the same, the name is unified in the vertical part and the vertical frame part is defined as being included in the name of this vertical part.

    In the natural ventilation device of the present invention, the vertical part itself is formed in advance in a structure having an indoor / outdoor communication structure and a ventilation adjusting chamber having two openings, and a ventilation amount adjusting plate is installed in the ventilation adjusting chamber so as to be swingable. It is easy to install just by devising a sealed structure, and because it is a vertical type, it is difficult for dust to accumulate. In addition, the ventilation adjustment plate can be moved to the second opening side according to the outside air inflow amount from the outside to automatically adjust the blowout to the indoor side, and the ventilation adjustment plate provided on the ventilation plate is in close proximity. By operating the means, the amount of air flowing in from the first opening can be limited in advance and sealed, so that a comfortable natural ventilation environment can be obtained.

    FIG. 1 is a cross-sectional view of a vertical portion of the embodiment, FIG. 2 is an external view showing a part of a fitting window, and FIG. 3 is a ventilation view seen from the inner side in FIG. FIG. 4 is a front view showing a method for attaching the ventilation amount adjusting plate by a hinge fitting, and FIG. 5 is a front view showing an example of the ventilation plate.

    FIG. 1 is a cross-sectional view of an example in which the indoor outlet, that is, the second opening, is on the left side. In normal times, comfortable wind from the outdoor side flows in and there is natural ventilation on the indoor side. This is a ventilator that can close the outside air inflow by manual operation when the wind with the blowout amount adjusted according to the outside air inflow amount from the outside flows indoors and the strong outdoor wind affects the indoor side. .

The configuration of the embodiment of the present invention will be described with reference to the drawings. The natural ventilation device of the present invention is provided in a vertical portion between curtain walls of glass 2 constituting a building exterior as shown in FIGS. . As shown in FIG. 1, the interior of the vertical portion 1 has a ventilation structure in which both indoors and outdoors are communicated, and an air flow adjusting chamber 5 is provided between the first opening 3 and the second opening 4 on the indoor side in the vertical portion. The air flow adjusting chamber 5 is provided with an air flow adjusting plate 7 having a tight rubber 6 for sealing around the front and back surfaces.
The ventilation amount adjusting plate 7 is swingably suspended by being connected to each other by four sets of hinge fittings 8 formed of parts having the same shape on both side walls of the ventilation adjusting chamber 5 and both side surfaces of the ventilation amount adjusting plate 7. The suspended state of the airflow adjustment plate 7 and the four sets of hinge fittings 8 is as shown in FIG. 4, and when one set of hinge fittings 8 is enlarged, it is as shown in FIG. When viewed from above, the connection status of the hinge bracket is as shown in FIG.
Therefore, the ventilation amount adjusting plate 7 is suspended in parallel with both openings 3 and 4 by its own weight, and is shaken by the respective hinge fittings 8 in the closing direction of both openings 3 and 4 by the wind pressure of the ventilation from the inside and outside. It is configured to be movable.

The tight rubber 6 seals the opening when the air flow adjusting plate 7 comes into contact with one of the first opening 3 and the second opening 4 by the wind pressure of the air from the inside and outside. belongs to.

    Further, a ventilation plate 9 is provided outside the second opening 4 and screwed, and a screw hole is formed in the middle of the ventilation plate 9, and a rotary knob 10 with a screw is provided in the screw hole. Is screwed with a lock nut 11, and a rubber cap 12 is attached to the tip of the screw. The rotary knob 10 has a function of screwing the rubber cap 12 at the tip into contact with the air flow adjusting plate 7 and then bringing the air flow adjusting plate 7 into contact with the first opening 3 and sealing the first opening 3. It has. It is also possible to forcibly set the blowout amount from the ventilation plate 9 by stopping the ventilation amount adjusting plate 7 halfway. FIG. 5 is a front view showing an example of the ventilation plate 9, but the ventilation plate 9 does not necessarily have such a shape because of its design.

Next, the operation will be described. In FIG. 1, the wind that has entered from the outdoor air flow inlet 13 on the vertical portion 1 proceeds as indicated by the arrow, enters the indoor side, and proceeds from the first opening 3 to the ventilation control chamber 5. At this time, if the air pressure of the air from the outside is of a level that does not move the air flow adjusting plate 7, the air flows as it is from the second opening 4 through the air vent plate 9 into the room. The aeration rate adjustment plate 7 as long as the extent that the wind pressure of the vent from the outside moves the airflow amount adjusting plate 7 when entering from the first opening portion 3 moves in accordance with the wind pressure adjustment to the second opening portion 4 side Thus, the amount blown out from the second opening 4 side is reduced. The indoor second opening 4 by Taitogomu 6 aeration amount adjusting plate 7 in contact with the second opening 4 if the wind pressure is the maximum is sealed wind Ri no longer flows, thus the wind strong As a result, the air flow rate adjusting plate 7 is appropriately swung to perform fully automatic natural ventilation.

Next outdoor wind strongly, if the aeration amount adjusting plate 7 in its wind pressure largely moves to the second opening portion 4 side, when you want to limit a small amount of wind than the amount that flows into the indoor by movement, The rotating knob 10 attached to the ventilation plate 9 is turned, and the contact position of the rubber cap 12 at the tip of the screw is set so as to stop the movement of the ventilation amount adjusting plate 7 on the first opening 3 side from the maximum movement position. When the adjusted upper lock nut 11 is screw-locked, the ventilation amount adjusting plate 7 has a rubber cap 12 abutting position at the tip of the screw as a maximum moving distance, and a small amount of wind restricted from the original inflow amount flows into the room. Become. In addition, when the outdoor wind pressure does not move the ventilation amount adjusting plate 7 that is suspended by its own weight, if a small amount of predetermined wind is desired to be put indoors, the screw lock of the rotary knob 10 is once released and further By turning the rotary knob 10, the rubber cap 12 at the tip of the screw is first brought into contact with the air flow rate adjusting plate 7, and then the air flow rate adjusting plate 7 is gradually pushed further into the first opening 3. Since the airflow adjustment plate 7 is gradually fixed and remains fixed in contact with the rubber cap 12 due to its own weight, the airflow entering the airflow adjustment chamber 5 is restricted by the airflow adjustment plate 7 and naturally. The amount of air blown into the branch will also be limited. When stopping the ventilation regardless of the outdoor wind, when the rotary knob 10 is turned to the end, the ventilation adjustment plate 7 comes into contact with the first opening 3 and the first opening 3 is sealed by the tight rubber 6 and is indoors. Wind will not flow into. Thus, this apparatus can also operate natural ventilation compulsorily manually.
