Specifically, FIG. 8( a ) is a diagram showing a state in which the valve body 8 is positioned to the normal position. Fig. 8(b) is a diagram showing a state in which the valve body 8 is positioned to the valve-opening position. Fig. 8(c) is a diagram showing a state in which the valve body 8 is positioned to the valve closing position.

The valve body 8 is normally positioned to the normal position shown in Fig. 8(a).

(Other implementations)

The modes for implementing the present invention have been described so far, but the present invention should not be limited to only the above-mentioned embodiments.

In the above-mentioned embodiment, as the door and window 1, an embedded window constituting a part of the curtain wall is exemplified, but the door and window of the present invention are not limited to be used in the curtain wall, and can also be various windows arranged on the outer wall of the building; Doors and windows for entrances and exits such as indoor and outdoor entrances or bathrooms. Furthermore, in the actual In the form, although the door and window 1 is used as an example of a fixed window in which the surface component 3 is fixed, the window is not limited to the embedded window, and can also be a two-way sliding window or a one-way sliding window in which the surface component, that is, the window sash, is supported and can be opened and closed. Windows, up and down windows, horizontal push-out windows, etc. have various types of switches.

In the above-described embodiment, as the valve body of the present invention, a valve body (on-off valve) that rotates around the rotating shaft portion 83 is used, but it is not limited to this, and, for example, a spherical body described in Patent Document 1 may be used. Wait for the valve body that will not turn. In addition, a configuration without a valve body may be adopted.

In the above-mentioned embodiment, the long hole 116 is provided in the drainage device body 7, and the rotating shaft portion 83 is provided in the valve body 8, but it is not limited to this. For example, the long hole of the present invention may be provided in the valve body, and the rotating shaft portion of the present invention may be provided in the drainage device body. At this time, the rotating shaft portion of the present invention is formed separately from the drain device body, and is inserted into the hole provided in the drain device body and the long hole provided in the valve body.

In the above-mentioned embodiment, there are two receiving ports OP, and the number of the receiving ports OP can also be one or more than three.

In the above-mentioned embodiment, the first inclined surface 101 is formed by a flat surface, but it is not limited to this, as long as it is inclined downward from the outer edge of the lower surface 100 to the center of the lower surface 100 , it can also be formed as a curved surface.

The drainage device of the present invention is a drainage device for discharging water accumulated in a frame material, and includes a drainage device body having: a cylindrical body having a drainage channel penetrating in a vertical direction; and a ceiling a face portion, which is arranged on the upper end of the cylindrical body and covers the drainage channel, and a receiving port is arranged in the drainage device body, which is fastened to the side opening, and connects the drainage channel and the drainage device body. The lower surface of the top surface is provided with a first inclined surface, which constitutes an upper edge among the receiving openings, and increases from the outer edge of the lower surface to the center of the lower surface. Lean downwards.

In the present invention, since the above-mentioned first inclined surface is provided on the lower surface of the top surface portion, a structure is formed in which the water permeating into the receiving port is easily contacted with the first inclined surface. Then, the water contacting the first inclined surface is attracted to the inside of the drainage device body through the surface tension, and then falls down through the drainage channel due to its own weight, thereby draining the water.

Therefore, even when the kinetic energy of the water accumulated in the frame material is small, the water can be discharged in the above-mentioned manner to improve the drainage performance.

In addition, in the drainage device of the present invention, the cylindrical body is provided with a second inclined surface, which constitutes a lateral edge in the receiving port, and is arranged to flow from the drainage channel to the drainage The outside of the device body expands the opening area of the receiving port.

According to the present invention, since the second inclined surface is provided in the cylindrical body, the opening area of the receiving port can be expanded, and the water accumulated in the frame material can be smoothly penetrated into the drainage channel through the receiving port. In addition, the second inclined surface may have the same function as the first inclined surface (the function of being in contact with water and attracting the water to the inside of the drainage device body), further improving the drainage performance.

In addition, in the drainage device of the present invention, when viewed from above, the first inclined surface extends across the inner peripheral surface of the cylindrical body.

According to the present invention, since the first inclined surface extends as described above, the water sucked into the inside of the drainage device body through the first inclined surface can be effectively dropped into the cylindrical body (drainage passage), and the drainage can be further raised. performance.

In addition, in the drainage device of the present invention, a valve body is further provided in the drainage channel and can be moved to a normal position, a valve-opening position, and a valve-closing position, respectively, inside the cylindrical body The peripheral surface is provided with a water blocking surface that the valve body abuts on, and one of the cylindrical body and the valve body is provided with a long hole; the other of the cylindrical body and the valve body is provided is set to be inserted into The rotating shaft portion of the long hole, the normal position is that the rotating shaft portion is located at one end side of the long hole in the longitudinal direction, and the gap between the water blocking surface and the valve body is the first gap. The valve opening position is that the valve body positioned to the normal position rotates with the rotating shaft as the center, and the gap between the water blocking surface and the valve body is larger than the first gap The position of the larger second gap; the valve closing position is the position where the rotating shaft portion is located on the other end side in the longitudinal direction of the long hole, and the valve body abuts on the water blocking surface.

In the present invention, the valve body is generally positioned to the normal position based on its own weight. In addition, the valve body positioned in the normal position receives a load due to the water permeating the drain passage through the receiving port, rotates around the rotating shaft portion, and is positioned at the valve opening position. Thereby, the water permeating into the drainage channel through the receiving port is discharged. In addition, the valve system is positioned to the valve closing position by applying pressure from outside the drain device so that the movement of the valve body is guided based on the long hole and the rotating shaft portion. Thereby, the backflow of rainwater, wind, etc. from the outside of the drainage device can be prevented through the drainage device.

Here, in the normal position, the gap (first gap) between the water blocking surface and the valve body is a smaller gap than the gap (second gap) in the valve-opening position. That is, since drainage is not required in a normal state, the gap (first gap) between the water blocking surface and the valve body can be made relatively small. Therefore, it is possible to prevent the outdoor wind from flowing into the room through the drainage device (the gap) in the environment including the blowing degree of the natural wind (for example, 12 m/s or less) in a windless state.

Further, according to the present invention, in the drainage device, the longitudinal direction of the long hole is inclined with respect to the vertical direction.

According to the present invention, since the longitudinal direction of the long hole is inclined with respect to the vertical direction, the valve body can be rotated from the normal position to the valve opening position at the position away from the water blocking surface. That is, the water blocking surface can be set at a position where the valve body does not mechanically interfere with the valve body when it rotates. Therefore, when the valve body is positioned to In the valve-closed position, the contact between the valve body and the water-blocking surface can be reliably performed, and the water-blocking performance in the valve-closed position can be improved.

Further, according to the present invention, in the drainage device, the long hole is provided in the cylindrical body, and the rotating shaft portion is provided in the valve body.
