  The present invention relates to a vent valve for opening and closing a ventilating passage for joinery, a drainage valve device for opening and closing a drainage passage for a joinery, and a joinery including the joinery valve device. .

In joinery, ventilating passages that communicate indoors and outdoors are formed in the upper frame of the joinery frame or on the top of the shoji, and a ventilating valve is provided in the passage to form a ventilator. By opening the passage, the room and the outside communicate with each other to ventilate the room, and the ventilation valve closes the passage to prevent rainwater or the like from flowing through the passage and entering the room.
For example, in Patent Document 1, a ventilation passage is formed in the upper frame of a joinery frame, and a wind plate is swingably suspended in the middle of the passage to be a ventilation valve. A ventilator is disclosed in which the passage is opened by moving away from the upper frame convex plate and swinging by the strong wind acting on the wind moving plate so as to contact the upper frame convex plate and close the passage. ing.
Japanese Utility Model Publication No.59-154598

In the conventional ventilation device described above, an unpleasant sound is generated when the wind plate, which is a valve for ventilation, abuts against the convex plate of the upper frame, and therefore an unpleasant sound is generated when the ventilation passage is closed. .
In particular, since the wind plate described above is swung by a strong wind and collides with the upper frame convex plate, a larger unpleasant sound is generated.

  In the conventional ventilator described above, an airtight material is attached to the wind plate and the upper frame convex plate so that the airtight material contacts each other when the wind plate swings. Since an unpleasant sound is generated when touching, an unpleasant sound is generated when the ventilation passage is closed.

  An object of the present invention is to provide a fitting device that can open and close a passage with a valve and that does not generate unpleasant noise when the passage is closed, and a fitting including the valve device. .

The valve device for joinery of the present invention is a valve device for joinery that opens and closes a passage through which a fluid formed in the joinery flows with a valve,
A groove-shaped valve body mounting portion having a substantially semicircular recess and an opening for opening the recess into the passage is provided above the passage, and the valve body is provided below the passage. Having a contact part,

The attached portion has an arc surface on which the valve body is provided and a plane continuous with the arc surface, and the attached portion can be deformed and rotated in the opening / closing direction into the recessed portion through the opening. In a substantially semicircular cross section that fits and forms a space between the recessed portion and the arcuate surface of the attached portion, a plane,
Said valve body is mounted suspended swingably opening and closing direction, by swinging in the direction the valve body is closed, the contact portion of the valve body abuts on the valve body abutment portion By closing the passage and swinging in the direction in which the valve body opens, the contact portion is separated from the valve body contact portion to open the passage,
The fitting valve device is characterized in that a pile is provided on at least one of the contact portion and the valve body contact portion.

In the present invention, a pile is attached to the contact portion of the valve body so as to face the valve body contact portion,
The valve body may swing in a closing direction by its own weight so that the pile contacts the valve body contact portion.
By doing so, the valve body swings in the closing direction, so that the pile provided at the contact portion of the valve body contacts the valve body contact portion and closes the passage, so that an unpleasant sound is generated. There is nothing.
Further, when the external force does not act on the valve main body, the pile contacts the valve main body contact portion and closes the passage, so that the valve main body is swung by a large external force such as strong wind and contacts the valve main body contact portion. No unpleasant sound is generated even when a large external force is applied.

  The joinery of this invention is a joinery provided with the valve device for joinery of this invention mentioned above.

According to the joinery valve device of the present invention, the valve main body is swung in the opening direction and the closing direction, so that the contact portion of the valve main body is separated from the valve main body contact portion or the passage is opened and closed. The passage can be opened and closed with a valve.
Further, when the passage is closed, the pile contacts with a point contact, so that no unpleasant sound is generated and no unpleasant sound is generated when the passage is closed.
Moreover, it is possible to attach to a recessed part through the opening part of a valve main body attaching part by deform | transforming the to-be-attached part of the one end part of a valve main body.
Further, since the portion other than the portion near the one end of the valve main body is made of a hard material, the valve main body reliably swings in the opening / closing direction.

As shown in FIG. 1, a shoji 2 is attached to a joinery frame 1 so as to be freely opened and closed.
The joinery frame 1 has an upper frame 3, a lower frame 4, and left and right vertical frames 5 connected in a square shape.
The shoji 2 has an upper collar 6, a lower collar 7, and left and right vertical collars 8 connected in a square shape, and a face material 9 is mounted therein.
The joinery shown in FIG. 1 is a folding door in which two shojis 2 can be folded. It is not restricted to this, A hinged door, a single sliding door, a 3 piece sliding door, etc. may be sufficient.
The joinery of this embodiment is a bathroom joinery. However, the present invention is not limited to this, and doorway fittings, window fittings, and the like that partition the room and the outdoors may be used.

As shown in FIG. 2, the joinery has a passage through which a fluid such as air or rainwater flows, for example, a ventilation passage 10 through which air flows through the upper frame 3.
This ventilation passage 10 communicates one side in the out-of-plane direction and the other side in the out-of-plane direction, for example, the dressing room side and the bathroom side with the joinery as a boundary.
A valve that opens and closes the passage 10, for example, an exhaust valve 20, is attached to the joinery, for example, the upper frame 3, and serves as a joinery valve device according to the present invention.

The valve 20 is attached to one end of the valve body 21 so as to be swingable in the direction in which the passage 10 is closed and opened in the upper frame 3, for example, in the out-of-plane direction. It is a thing.
The pile 22 has a large number of thin linear pieces and is called, for example, mohair.
The valve body 21 swings in one out-of-plane direction (closing direction) with one end as a fulcrum, so that the pile 22 contacts the upper frame 3 and closes the passage 10.
The valve body 21 swings in the out-of-plane direction to the other side (opening direction) with one end serving as a fulcrum, so that the pile 22 is separated from the upper frame 3 to open the passage 10.
Closing the passage 10 described above prevents fluid such as air from flowing through the passage 10, and opening the passage 10 means flowing fluid such as air through the passage 10.

Since this is the case, the valve body 21 swings to one side in the out-of-plane direction, so that a large number of thin linear pieces of the pile 22 provided on the valve body 21 abut on the upper frame 3 by point contact. So there will be no unpleasant sound.
Therefore, it is possible to provide a fitting valve device that does not generate unpleasant noise when closing the passage 10.
In this embodiment, the pile 22 is provided in the portion that contacts the upper frame 3 of the valve body 21, but the pile 22 may be provided in the portion of the upper frame 3 that contacts the valve body 21, or provided in both. Also good.
In short, the pile 22 should just be provided in the part which the valve main body 21 and the channel | path 10 side contact | abut.

In this embodiment, the valve body 21 swings in the out-of-plane direction side (closing direction) by its own weight, and the pile 22 abuts on the upper frame 3, and external force acting on the valve body 21, for example, out-of-plane direction. Due to the pressure difference between one side and the other side in the out-of-plane direction, the valve body 21 swings in the other side in the out-of-plane direction (opening direction) and the pile 22 is separated from the upper frame 3, so that a large external force acts on the valve body 21 However, no unpleasant sound is generated.
This embodiment is a bathroom fitting, and when venting the air inside the bathroom to ventilate the bathroom, the pressure inside the bathroom becomes negative, and the pressure difference becomes lower than the pressure inside the dressing room. And the valve main body 21 swings in the other direction in the out-of-plane direction.

Next, an example of the specific shape of each part is demonstrated based on FIGS.
The upper frame 3 has a valve body mounting portion 30 in an upper part of the passage 10 and a valve body contact portion 40 in a lower part of the passage 10.
The attached portion 23 at one end (upper end) of the valve body 21 is attached to the valve body attachment portion 30 so as to be rotatable in an out-of-plane direction, and the valve body 21 is suspended so as to be swingable in an out-of-plane direction. . The other end (lower end) of the valve body 21 is a contact portion 24 that contacts the valve body contact portion 40, and the pile 22 is attached to the contact portion 24.
In this embodiment, the upper frame 3 has an in-plane direction outer member 3a and an in-plane direction inner member 3b, and the in-plane direction outer member 3a and the in-plane direction inner member 3b are separated in the in-plane direction. The ventilation passage 10 is provided between the two.

As shown in FIG. 3, the valve body mounting portion 30 has a groove shape having a substantially semicircular recess 31 and an opening 32 that opens the recess 31 into the passage 10. The attachment portion 30 is continuous with the entire length of the upper frame 3 in the longitudinal direction.
The valve main body abutting portion 40 has a flat surface 41 that extends in the up-down direction and continues to the entire length in the longitudinal direction of the upper frame 3.
The valve main body 21 is plate-shaped as shown in FIGS. 3 and 4, and the attached portion 23 provided at one end thereof has a cross-section that fits into the recessed portion 31 so as to be rotatable in an out-of-plane direction. The valve main body 21 is integrally provided on the arc surface 23 a in a semicircular shape, and the flat surface 23 b faces the arc inner surface 31 a of the recessed portion 31.
A space 33 is formed between the arc inner surface 31 a of the recessed portion 31 and the arc surface 23 a and the flat surface 23 b of the attached portion 23.

A pile 22 is provided at the other end of the valve body 21, that is, at the contact portion 24 facing the valve body contact portion 40 of the upper frame 3.
This pile 22 is obtained by implanting a large number of thin linear pieces 22b on a substrate 22a, and the substrate 22a is fixedly attached to the abutting portion 24 of the valve body 21 by adhesion or the like. The thin linear piece 22b may be directly implanted in the contact portion 24 of the valve body 21.
A large number of linear pieces 22 b of the pile 22 abut on the flat surface 41 of the valve body abutting portion 40.

The valve main body 21 swings in the out-of-plane direction side (closing direction) by its own weight, and the pile 22 is held in a state of being in contact with the valve main body contact portion 40. For example, the swing center 21 a of the valve body 21 is located closer to the one side in the out-of-plane direction (closer to the closing direction) than the valve body contact portion 40.
Therefore, the valve body 21 is restrained from swinging to the other side in the out-of-plane direction due to vibration or the like.

The valve body 21 has a portion 21b near the attached portion 23 made of a soft material and the remaining portion 21c made of a hard material.
By doing in this way, the to-be-attached part 23 can be deform | transformed etc. and can be pushed in and attached to the valve body attaching part 30. Therefore, since the valve main body 21 can be attached and detached after assembling the joinery, maintenance is easy.
That is, since the valve main body attaching portion 30 is made of a hard material such as aluminum, if the attached portion 23 of the valve main body 21 is made of a hard material, it cannot be attached or detached after assembling the joinery.
Moreover, since the other part 21c of the valve main body 21 is made of a hard material, the valve main body 21 is reliably swung in the out-of-plane direction.
That is, if the entire valve body 21 is made of a soft material, the entire valve body 21 is curved and is difficult to swing.
The entire valve body 21 may be made of a hard material.

Next, test examples of the present invention will be described.
Using the upper frame 3 shown in FIG. 3, the volume (dB) under an arbitrary condition was measured when the valve main body 21 was different from the valve main body 21 and contacted with the valve main body contact portion 40 of the upper frame 3.
As shown to Fig.5 (a), in the case of the valve main body 21 which does not provide the pile 22, the sound volume was 66.0 (dB).
As shown in FIG. 5B, in the case of the valve main body 21 in which the pile 22 is not provided and the valve main body contact portion 24 is made of a soft material, the sound volume was 62.2 (dB).
As shown in FIG. 5C, in the case of the valve main body 21 in which the length of the pile 22 is 1.5 mm, the sound volume was 58.1 (dB).
As shown in FIG. 5D, in the case of the valve body 21 in which the length of the pile 22 is 2.0 mm, the volume is 51.5 (dB).

  From these facts, it was found that by providing the pile 22 on the valve body 21, the volume generated when contacting the valve body contact portion 40 can be reduced.

In each of the above-described embodiments, the valve body 21 swings in the closing direction by its own weight and swings in the opening direction by an external force. However, the valve body 21 swings in the closing direction by an external force and passes through the passage. When the external force is closed, it may be swung in its opening direction by its own weight.
For example, in FIG. 3, the valve body mounting portion 30 is formed at a position closer to the other side in the out-of-plane direction than shown, and the swing center 21 a of the valve body 21 is located on the other side in the out-of-plane direction from the valve body contact portion 40 ( When no external force acts on the opening side), the valve body 21 hangs down and the pile 22 moves away from the valve body contact portion 40 to open the passage 10, and the valve body 40 is piled toward the one side in the out-of-plane direction by the external force. 22 abuts on the valve body abutting portion 40 to close the passage 40.
Further, the valve main body abutting portion 40 is provided at a position where the other end portion of the valve main body 21 contacts the valve main body abutting portion 40 before the center of gravity of the valve main body 21 comes directly below the swing center 21 of the valve main body 21. Thus, the valve body 21 may swing by its own weight in the closing direction so that the pile 22 contacts the valve body mounting portion 40.

It is a front view of the joinery which shows embodiment of this invention. It is a longitudinal cross-sectional view of joinery. It is an enlarged view of a passage part. It is a partial front view of a valve. It is explanatory drawing of the various valves used for the test example.
