Patent Document 1: Japanese Laid-Open Patent Publication No. 2015-190682.

As described above, in the configuration of Patent Document 1, the outer panel cover is fixed to the outdoor side of the casing, and the air volume adjusting plate can be moved inside. Therefore, the movable range of the air volume adjusting plate is limited to the depth of the frame, and it is very difficult to ensure the ventilation efficiency, especially the weak wind.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a ventilating device capable of improving ventilation efficiency and a door and window including the ventilating device.

The present invention provides a ventilator including a frame having an opening that communicates in the indoor and outdoor directions, and a blade member that moves in a direction in which the opening is opened and closed on the outdoor side of the opening. And adjusting the air volume passing through the opening; and the outer panel is supported by the frame on the outdoor side of the blade member, and is capable of opening and closing the opening; wherein the blade member is opposite to the frame or the outer panel It is rotatably supported and is subjected to a load in an opening direction which is moved to the outdoor side to open the opening, and the blade member and the outer panel can each be at least a part of the outdoor side facing room of the frame The opening operation is performed until the outer side protrudes from the rotational position.

According to such a configuration, the ventilating device can open the blade member and the outer panel to a position projecting outward from the outdoor side of the outdoor side when the air is ventilated. Therefore, the depth of the ventilating device (frame) can be minimized, and the opening area of the ventilating opening can be largely ensured. Further, it is possible to efficiently introduce the wind (building wind) flowing along the outer wall of the building in which the ventilating device is installed. As a result, sufficient ventilation performance can be obtained even in the absence of wind or weak wind, thereby improving ventilation efficiency.

In the ventilating device according to the present invention, the wind receiving surface may be provided at a front end portion of the blade member, and the wind receiving surface may be in a state in which the blade member abuts or approaches the outer panel. The inner side of the outer panel extends in a direction away from the indoor side. Thus, when the blade member starts moving, the wind pressure can be efficiently received by the wind receiving surface. As a result, it can be avoided that the blade member is in close contact with the inner surface of the outer panel, and the wind pressure cannot be efficiently received, so that it is difficult to start moving.

In the ventilating device according to the present invention, the wind receiving surface may be provided in a blade tip end member which is a blade tip end member that is attached to a tip end portion of the blade member and has flexibility, or A blade tip end member that is rotatably attached to a front end portion of the blade member. Thus, when the blade member moves, the blade tip end member is deformed or rotated by the wind pressure received by the wind receiving surface, and the wind pressure can be received in a direction closer to the vertical direction. As a result, the blade member can more efficiently withstand wind pressure.

In the ventilator of the present invention, a waterproof sheet may be formed on the inner surface of the blade member, and the waterproof sheet may be interposed in a state in which the blade member moves toward the indoor side to close the opening. The inner surface is in a ventilation path formed between the opening. Thus, even if it is subjected to wind and rain when the ventilation device is ventilated, for example, it is possible to trap rainwater with the waterproof sheet. As a result, it is possible to prevent rainwater or the like from penetrating into the indoor side.

In the ventilator according to the present invention, the blade member and the outer panel may be supported by one side of the opening, and each of the opening directions may be the same. In this way, the blade member and the outer panel are opened in the same direction from the outer wall surface of the building, for example, so that the building wind or the like blown along the outer wall surface can be introduced more efficiently, and the ventilation efficiency can be further improved.

In the ventilation device according to the present invention, the inner panel may be configured to be supported by the frame on the indoor side of the opening, and to open and close the opening; and the link mechanism The opening and closing operation of the outer panel is interlocked with the opening and closing operation of the inner panel. As described above, by opening the inner panel from the indoor side, the outer panel and the blade member following it can be opened, and the ventilation operation can be easily performed.

The present invention provides a door and window, comprising: a ventilating device having the above configuration; and a window connected to at least one vertical frame of the frame body. According to such a configuration, the ventilating device and the window can be provided as a single door and window on the building, and the appearance quality and the construction efficiency are high.

According to the present invention, the ventilation efficiency can be improved.

The ventilation path S is partitioned by the partition wall 28 into an indoor side path S1 and an outdoor side path S2, and these paths S1 and S2 are communicated by the opening 22, respectively. The partition wall 28 is formed in a frame shape by the upper piece 28a and the lower piece 28b which protrude inward from the inner side depth direction of the upper frame 20a and the lower frame 20b, and the vertical sheets 28c and 28d which protruded inward from the inner side depth direction of the vertical frames 20c and 20d. . In the case of the present embodiment, the upper piece 28a is provided on the inner wall member 29a attached to the inner depth surface of the upper frame 20a, and the lower piece 28b is provided on the inner wall member 29b attached to the inner deep surface of the lower frame 20b. . The inner wall members 29a, 29b may be integrally formed with the respective frames 20a, 20b.

A screen door window 30 is provided on the opening portion 22. The screen door window 30 is mounted and fixed to the inner side depth surface of each of the sheets (28a to 28d). The screen door window 30 can also be configured to be openable and closable using a guide rail or the like.

The inner panel 24 is a door leaf that is rotatably supported on one side of the vertical frame 20d on the indoor side of the opening 22 . A shaft piece 24a along the vertical direction is provided at one side of the inner side panel 24. On the inner deep surface of the vertical frame 20d, a hinge piece 32 in the vertical direction is provided at a position on the indoor side of the vertical piece 28d. The shaft piece 24a and the hinge piece 32 are rotatably engaged to form a hinge for rotation of the inner side panel 24. The inner panel 24 can be extended from the fully closed position (see FIG. 3 ) accommodated in the depth of the frame 20 to the fully open position (see FIG. 4 ) that protrudes from the indoor side main viewing surface 33 of the casing 20 to the indoor side. Opening and closing.

The inner panel 24 has a hollow structural portion 24b having a thickness in the depth direction as viewed from the front, at a portion corresponding to the opening portion 22. The hollow structure portion 24b is in a state of occupying most of the indoor side path S1 of the ventilation path S at the fully closed position. The upper and lower edge portions of the hollow structural portion 24b are in contact with the airtight members 34 attached to the respective sheets 28a and 28b. A door stopper piece 24c is provided on each of the upper, lower, left and right edge portions of the inner panel 24 in the depth direction indoor side. Each of the door stopper pieces 24c abuts against the airtight member 34 attached to the protruding piece provided on the inner deep surface of each of the frames (20a to 20d). Thereby, the inner panel 24 abuts on each of the airtight members 34 at the upper and lower left and right edge portions in the fully closed position, thereby ensuring airtightness and watertightness (see FIGS. 3 and 5). A handle 36 for opening and closing operation is attached to the inner side surface of the inner panel 24.

The outer side panel 25 is a door leaf that is rotatably supported on one side of the vertical frame 20d on the outdoor side of the opening 22 . A shaft piece 25a in the vertical direction is provided at one side of the outer side panel 25. On the inner deep surface of the vertical frame 20d, a hinge piece 38 along the vertical direction is provided at a position on the outdoor side of the vertical piece 28d. The shaft piece 25a and the hinge piece 38 are rotatably engaged to form a hinge for rotating the outer side panel 25. The outer panel 25 can be moved from a fully closed position (see FIG. 3 ) accommodated in the depth of the frame 20 to a fully open position (see FIG. 4 ) that protrudes outward from the outdoor side main view surface 37 of the casing 20 . Opening and closing.

The outer panel 25 has a bottomed container structure that is thinner than the inner panel 24 at substantially the same plane as the outdoor side main viewing surface 37 of the casing 20 at the fully closed position. Side walls 25b and 25c that respectively protrude toward the indoor side are provided in the vicinity of the left and right side portions of the inner surface 39 of the inner side surface of the outer panel 25. The open end portion 25d of the outer side panel 25 on the side opposite to the hinge piece 38 side protrudes toward the vertical frame 20c than the side wall 25b. Thereby, it is not easy to visually recognize the shielding structure inside the apparatus from the gap between the outer side panel 25 and the vertical frame 20c in the fully closed position (refer FIG. 3).

A waterproof member 41 that is in contact with the upper end surface of the outer panel 25 at the fully closed position is provided at the outdoor side end portion of the inner side of the upper frame 20a. When the outer panel 25 in the open state is closed to the fully closed position, the waterproof member 41 is slidably attached to the upper end surface of the outer panel 25, and has a function of sweeping rainwater or the like accumulated on the upper end surface to the outside. The waterproof member 41 can also prevent rainwater or the like from infiltrating into the outdoor side path S2 from the gap between the outer panel 25 and the upper frame 20a in the fully closed position.

As shown in FIGS. 3 to 5, the opening and closing operations of the inner panel 24 and the outer panel 25 are interlocked by the pair of upper and lower link mechanisms 40. Each link mechanism 40 has a pair of arm members 42, 43 and a slider 44. Each of the link mechanisms 40 has a vertically symmetrical structure, and the other configuration is the same. Therefore, the lower link mechanism 40 will be mainly described below, and the upper link mechanism 40 will be given the same reference numeral and will not be described in detail. .

One end portion of one arm member 42 is rotatably coupled to the inner panel 24 via a rotating shaft 42a, and the other end portion is rotatably coupled to the slider 44 via a rotating shaft 42b. One end portion of the other arm member 43 is rotatably coupled to the outer panel 25 via a rotating shaft 43a, and the other end portion is rotatably coupled to the slider 44 by a rotating shaft 42b shared with the arm member 42. The slider 44 is engaged so as to be slidable with respect to the guide rail 46 provided on the inner side of the lower frame 20b. The guide rail 46 is protruded from the inner side deep surface on the indoor side of the lower piece 28b provided on the inner wall member 29b constituting the lower frame 20b. The guide rail 46 extends in the longitudinal direction of the lower frame 20b. It should be noted that the guide rail 46 of the upper link mechanism 40 is protruded from the inner deep side on the inner side of the upper piece 28a provided on the inner wall member 29a constituting the upper frame 20a.

Therefore, in a state where the inner panel 24 and the outer panel 25 are in the fully closed position, the link mechanism 40 is at the sliding position of the vertical frame 20d of the slider 44 closest to the hinge side of each of the panels 24 and 25 (see FIG. 3). When the inner side panel 24 is opened to the indoor side by the handle gripping lever 36, the one arm member 42 is opened to the indoor side with the rotating shaft 42b on the slider 44 side as a center of rotation. Thereby, the slider 44 is pulled by the arm member 42, and slides from the side of the vertical frame 20d to the side of the vertical frame 20c on the opposite side. At this time, the arm member 43 on the other side is pressed by the sliding slider 44, and the outer panel 25 is pressed toward the outdoor side. Then, the outer panel 25 is interlocked with the inner panel 24, and the opening operation is also performed. Finally, as shown in FIG. 4, the slider 44 abuts against the stopper 47 provided on the guide rail 46, and each of the panels 24, 25 is in the fully open position. In this state, the slider 44 is held by the holding spring 48 attached to the stopper 47, so that the fully open state of each of the panels 24, 25 can be maintained.

On the other hand, when the inner panel 24 is closed toward the opposite side of the opening operation, the slider 44 is detached from the holding spring 48, and this time it slides toward the vertical frame 20d side, so that the outer panel 25 also performs the closing operation.

In addition, as shown in FIG. 5, the slider 44 is arrange|positioned in the indoor side rather than the upper sheet 28a and the lower sheet 28b. Therefore, the upper and lower arm members 43 on the side of the outer panel 25 are respectively inserted into the through holes 45 provided in the upper piece 28a and the lower piece 28b. Here, the outdoor side of the through hole 45 is plugged by the brush strip 49 to prevent foreign matter such as insects or garbage from entering the indoor side from the through hole 45. It should be noted that foreign matter enters the indoor side from the opening portion 22 and is prevented by the screen door window 30.

As shown in FIGS. 3 to 5, the blade member 26 is rotatably supported by the vertical frame 20d on one side of the outdoor side of the opening 22. The blade member 26 can be supported in such a manner as to be rotatable relative to the outer panel 25. A shaft member 50 extending in the vertical direction along the vertical frame 20d is provided at one side of the blade member 26. On the inner side of the frame 20, a bearing member 52 is provided on the outdoor side of the vertical piece 28d and on the indoor side of the hinge piece 38. The shaft member 50 is rotatably supported around the bearing member 52 so that the blade member 26 is supported to be rotatable relative to the vertical frame 20d. The blade member 26 can be fully closed from the fully closed position (see FIG. 3 ) accommodated in the outdoor side path S2 within the depth of the casing 20 to the outdoor side of the outdoor side main view surface 37 of the casing 20 ( Referring to Fig. 4), opening and closing is performed. The blade member 26 is always subjected to a load in an opening direction that moves to the outdoor side.

The blade member 26 is a plate-shaped member, and has a door stop portion 26b, an inclined portion 26c, a main body portion 26d, and a front end portion 26a in this order from the hinge member-side shaft member 50 toward the open end side end portion 26a. The blade member 26 is an extruded material of a resin such as aluminum or a resin such as polyvinyl chloride resin (PVC).

The door stopper portion 26b is a plate extending from the vertical direction of the vertical frame 20d toward the vertical frame 20c (hereinafter referred to as "X1 direction") in the X direction from the shaft member 50 as a reference. unit. The inclined portion 26c is a plate portion that gradually inclines toward the outdoor side from a position slightly closer to the base end than the front end of the door stop portion 26b toward the X1 direction. The main body portion 26d is a plate portion that extends in the X1 direction at a position that abuts or approaches the inner surface 39 of the outer panel 25. Two waterproof sheets 54 are protruded from the inner surface of the main body portion 26d. The front end portion 26a is a pocket-shaped portion provided at the front end portion of the main body portion 26d, and the blade leading end member 56 is mounted therein.

The blade member 26 forms a vent 62 at a gap between the blade leading end member 56 provided at the front end portion 26a and the vertical frame 20c. The air vent 62 serves as an air inlet that enters the room from the outside through the opening 22, and the opening area changes in accordance with the movement of the blade member 26. The air passage 62 has the smallest opening area when the blade member 26 is in the fully closed position, and the opening area is the largest when the blade member 26 is in the fully open position. In the case of this embodiment, as is clear from Fig. 3, the fully closed position of the blade member 26 does not mean the position where the air inlet 62 (and the opening 22) is completely closed, but the position where the opening area is the smallest.

Each of the waterproof sheets 54 is arranged side by side in the X direction on the inner surface of the main body portion 26d. Each of the waterproof sheets 54 is a plate portion that is gradually inclined toward the indoor side in the X1 direction and whose front end is bent in the X1 direction. Each of the waterproof sheets 54 is a member for removing moisture such as rainwater that flows into the outdoor side path S2 from the gap between the open end portion 25d of the outer panel 25 and the vertical frame 20c and flows toward the opening portion 22 along the inner surface of the blade member 26.

The waterproof blade 58 (see the two-dot chain line in FIG. 3) may be attached to the vertical frame 20c (vertical sheet 28c). That is, when the waterproof sheet 54 and the waterproof blade 58 are alternately arranged at the fully closed position of the blade member 26, a crank-shaped waterproof path can be formed, and the waterproof performance can be further improved. The waterproof blade 58 has a structure in which the main body portion 26d of the blade member 26 is substantially reversed, and has a pair of waterproof sheets 58a that are alternately arranged with the waterproof sheet 54.

The blade leading end member 56 is formed of a rubber-based material or a resin-based material or the like, and is a member having flexibility and a certain degree of rigidity. The blade leading end member 56 is disposed to gradually incline toward the indoor side from the front end portion 26a toward the X1 direction. In other words, the blade tip end member 56 is in a direction away from the inner face 39 of the outer panel 25 toward the indoor side in a state in which the blade member 26 abuts or approaches the inner face 39 of the outer panel 25 (see FIGS. 3 and 4). Extend. Therefore, in a state where the blade member 26 abuts or approaches the inner face 39, a gap G is formed between the blade tip end member 56 and the inner face 39. At this time, the tip end of the blade tip end member 56 is in a state of protruding toward the indoor side from the depth of the outer panel 25 (the side wall 25b) (see FIG. 3). The surface (outer surface) on the side of the gap G of the blade tip end member 56 functions as a wind receiving surface 56a that receives the wind that flows in from the ventilating port 62.

Next, the self-weight load mechanism 60 that operates the blade member 26 in the opening direction will be described. Fig. 6 is a front view showing the structure of the self-heavy load mechanism 60, and Fig. 6(A) shows a state in which the blade member 26 is in a state of no wind or weak wind, and (B) in Fig. 6 shows that the blade member 26 is subjected to A diagram of a strong wind state.

As shown in FIG. 6, the self-heavy load mechanism 60 has a shaft member 50 and a bearing member 52.

The shaft member 50 has a cylindrical body 50a that is provided on one side of the blade member 26 (a side portion on the side of the vertical frame 20d) and extends in the vertical direction; the pair of shaft portions 50b and 50b are from the cylindrical body 50a. The upper and lower openings respectively protrude upward and downward; the downward facing end surface 50c surrounds the lower shaft portion 50b. Each of the shaft portions 50b has a structure in which the proximal end portion is fitted into the tubular body 50a and the distal end portion projects upward and downward. However, the shaft portion 50b may be integrally formed with the tubular body 50a. The downward end surface 50c is an inclined surface (oblique surface) that is inclined in the vertical direction with respect to the axial direction of the shaft portion 50b. In other words, the downward end surface 50c has a shape in which the lower end portion of the cylindrical body 50a is cut in an oblique direction intersecting the axial direction.

The bearing member 52 is provided with a pair of upper and lower sides so as to correspond to the upper and lower shaft portions 50b and 50b. The upper bearing member 52 is a cylindrical body that rotatably supports the upper shaft portion 50b. The lower bearing member 52 is a cylindrical body that rotatably and freely supports the lower shaft portion 50b. The lower bearing member 52 is provided with an upward end surface 52a that surrounds the inserted shaft portion 50b. The upward end surface 52a is an inclined surface (oblique surface) that is inclined in the vertical direction with respect to the axial direction of the shaft portion 50b. In other words, the upward end surface 52a has a shape in which the bearing member 52 is cut in an oblique direction crossing the axial direction.

As shown in (A) of FIG. 6, in the state where the external force from the wind or the outer panel 25 is not applied to the blade member 26, the downward end surface 50c of the shaft member 50 and the upward end surface 52a of the bearing member 52 are in close contact with each other. It is formed in a cylindrical shape. In other words, in a state where no load other than the weight is applied to the blade member 26, the downward end surface 50c slides down on the upward end surface 52a due to the weight of the blade member 26, and the blade member 26 rotates in the opening direction. Therefore, the blade member 26 is in the fully open position shown in FIG.

When the blade member 26 is rotated in the closing direction by the external force from the wind or the outer panel 25 in the state shown in FIG. 6(A), the downward end surface 50c is facing as shown in FIG. 6(B). The upper end surface 52a is slid upward, and the blade member 26 is rotated in the closing direction. Therefore, in a state in which the blade member 26 is in the fully closed position shown in FIG. 3, the blade member 26 is placed at a position where the height H in FIG. 6 is raised from the fully closed position.

The mechanism that operates the blade member 26 in the opening direction may be a mechanism other than the heavy-duty load mechanism 60. For example, instead of the self-heavy load mechanism 60, a coil spring 64 or a torsion spring 66 indicated by a two-dot chain line in Fig. 3 may be used. The coil spring 64 is coupled between the blade member 26 and the inner surface 39 of the outer panel 25, and is an elastic body that always urges the blade member 26 toward the opening direction of the outer panel 25. The torsion spring 66 is fitted over the shaft member 50 as an elastic body that always urges the blade member 26 toward the opening direction.

Next, the operation of the ventilation device 10 will be described. Fig. 7 is a cross-sectional view showing the operation of the blade member 26 when wind power is applied to the ventilating device 10, and Fig. 7(A) is a view showing a state in which the blade member 26 is in a state of no wind or weak wind, and Fig. 7 (B) is a state in which the blade member 26 is moved from the state shown in (A) of FIG. 7 to the closing direction, and (C) in FIG. 7 is the blade member 26 shown in (B) of FIG. A diagram of a state in which the state is further moved in the closing direction.

When the inner panel 24 and the outer panel 25 are placed in the fully closed position as shown in FIG. 3, the blade member 26 is in a state of being pressed by the outer panel 25 in the closing direction. Therefore, the blade member 26 is in a position to slide up on the upward end surface 52a of the bearing member 52 against the downward end surface 50c of the shaft member 50 against the load in the opening direction by the own weight (refer to (B) of FIG. 6).

In this state, the blade member 26 is in a fully closed position in which the door stopper portion 26b abuts or approaches the vertical piece 28d (refer to FIG. 3). In addition, even in a state where the blade member 26 is in the fully closed position, the ventilating port 62 having the smallest opening area through which the wind can flow can be secured between the blade member 26 and the vertical piece 28c. However, in this case, the inner panel 24 is in the fully closed position and the indoor side of the ventilation path S (opening 22) is completely closed by the airtight member 34. Therefore, wind or rain does not enter the room.

Next, when the room is ventilated, the handle 36 is gripped to open the inner panel 24 to the indoor side. As a result, the outer panel 25 is also opened to the outdoor side by the link mechanism 40, and the pressing force from the outer panel 25 to the blade member 26 is released. Therefore, the blade member 26 performs the opening operation so as to follow the outer panel 25 that performs the opening operation by the self-weight imparted by the self-weighting mechanism 60 in the opening direction. When the inner panel 24 and the outer panel 25 are in the fully open position as shown in FIG. 4, the blade member 26 also abuts or approaches the inner surface 39 of the outer panel 25, and becomes a fully open position in which the further rotation in the opening direction is restricted.

In this state, the outer side panel 25 and the blade member 26 are largely extended toward the outdoor side (refer FIG. 4). Therefore, the opening area of the ventilation port 62 is maximized, and even if there is no wind or weak wind, the amount of air entering the room from the opening 22 can be ensured, and sufficient ventilation performance can be ensured.

When the ventilating device 10 receives strong wind in the state shown in FIG. 4, the wind that has flowed in from the ventilating port 62 is blown from the gap G to the wind receiving surface 56a of the blade tip end member 56. When the wind pressure received by the entire wind receiving surface 56a exceeds the self-weight applied to the blade member 26 in the opening direction by the self-heavy load mechanism 60, the blade member 26 starts to move in the closing direction (refer to the arrow shown by the two-dot chain line in Fig. 4). ). Further, when the wind force is increased, the blade member 26 gradually moves in the closing direction, and the opening area of the air passage 62 is reduced, thereby suppressing the amount of air flowing into the room. As a result, the amount of air entering the room through the opening 22 can be maintained substantially constant regardless of the size of the outdoor wind force, so that the air can be ventilated with a constant air volume.

However, after the blade member 26 is in the fully closed position shown by the two-dot chain line in Fig. 4, even if the wind force is further increased, the opening area of the ventilating opening 62 does not change. However, since the opening area of the ventilating opening 62 at this time is extremely small, the amount of air entering the room gradually increases, but it can be prevented from becoming excessive.

Further, when the blade member 26 is closed in this manner, when the blade member 26 is moved from the fully open position, the wind pressure of the wind W can be smoothly received by the wind receiving surface 56a of the blade distal end member 56 (refer to FIG. 7 ( A)). Therefore, it is possible to prevent the wind force required for the entire length of the blade member 26 to be in close contact with the outer panel 25 to start moving, so that the start movement of the blade member 26 is smoother. That is, in the state of (A) of FIG. 7, the blade member 26 is oriented in substantially the same direction as the direction of the wind W, and therefore, although it is in a state in which it is difficult to start by the turning operation of the shaft member 50, The blade leading end member 56 can be smoothly started. In addition, instead of the blade tip end member 56, the tip end portion 26a of the blade member 26 as a profile may have the same shape as the blade tip end member 56 (wind receiving surface 56a). Further, the blade tip end member 56 may be configured such that its root portion is rotatably supported by the tip end portion 26a of the blade member 26, and in this case, the blade tip end member 56 does not necessarily have to be flexible.

In the present embodiment, the blade tip end member 56 has flexibility. Therefore, the blade tip end member 56 is deformed as if it is turned toward the indoor side by the wind pressure received by the wind receiving surface 56a (refer to (B) of FIG. 7). Thus, the blade leading end member 56 can withstand the wind pressure of the wind W in a direction closer to the vertical direction, thereby making the blade member 26 start moving more smoothly. As a result, the blade member 26 can smoothly perform the closing operation due to the pressure receiving action of the blade tip end member 56 which is deformed as shown in Fig. 7(C). In addition, in the case where the blade tip end member 56 is rotatably supported by the tip end portion 26a of the blade member 26, the blade tip end member 56 is also as shown in FIGS. 7(B) to 7 . The structural example shown in (C) is rotated in the same manner, and the blade member 26 can smoothly synchronize the motion.

As described above, the ventilation device 10 of the present embodiment includes the housing 20 having the opening 22 that communicates in the indoor and outdoor directions, and the blade member 26 is in the opening 22 on the outdoor side of the opening 22. The opening and closing direction is moved to adjust the amount of air passing through the opening 22; and the outer panel 25 is supported by the frame 20 on the outdoor side of the blade member 26, and the opening 22 can be opened and closed. At this time, the blade member 26 is rotatably supported with respect to the frame body 20 or the outer side panel 25, and is subjected to a load in the opening direction of moving to the outdoor side to open the opening portion 22. Further, each of the blade member 26 and the outer panel 25 can be opened until at least a part thereof protrudes outward from the outdoor side main viewing surface 37 of the casing 20 toward the outdoor side.

As described above, the ventilating device 10 can open the blade member 26 and the outer panel 25 to a position that protrudes outward from the outdoor side main viewing surface 37 when the air is ventilated. Therefore, the depth of the ventilating device 10 (the casing 20) can be minimized, and the opening area of the vent 62 can be largely ensured. Further, it is possible to efficiently introduce the wind (building wind) flowing along the outer wall of the building in which the ventilation device 10 is installed. As a result, sufficient ventilation performance can be obtained even in the absence of wind or weak wind, thereby improving the ventilation efficiency. Further, since the blade member 26 is provided, the blade member 26 is pushed by the wind pressure during the strong wind to perform the closing operation, and the opening area of the ventilation port 62 is adjusted. Therefore, it is possible to perform the ventilation at the required constant air volume even in the case of strong wind or the like.

In the ventilating device 10, a wind receiving surface 56a is provided at the front end portion 26a of the blade member 26, and the wind receiving surface 56a is in a state of abutting or approaching the outer panel 25 of the blade member 26, on the outer panel 25 The inner surface 39 extends in a direction away from the indoor side. Thereby, when the blade member 26 starts moving, the wind pressure can be efficiently received by the wind receiving surface 56a. As a result, it can be avoided that the blade member 26 is in close contact with the inner surface 39 of the outer panel 25, and the wind pressure cannot be efficiently received, so that it is difficult to start moving.

In the ventilating device 10, the wind receiving surface 56a is provided in the blade tip end member 56 which is a blade tip end member 56 which is attached to the front end portion 26a of the blade member 26 and has flexibility, or is capable of The blade tip end member 56 is attached to the front end portion of the blade member 26 in a rotating manner. Thereby, when the blade member 26 moves, the blade tip end member 56 is deformed or rotated by the wind pressure received by the wind receiving surface 56a, so that the wind pressure can be received in a direction closer to the vertical direction. As a result, the blade member 26 can more effectively withstand the wind pressure. In addition, since the blade tip end member 56 has a flexible and flexible structure, when the blade member 26 is accidentally closed by the wind pressure or the like, it is possible to suppress the sandwiching between the blade member 26 and the frame body 20 Damage to the blade member 26 or the frame 20 caused by foreign matter or the like, or generation of noise.

In the ventilating device 10, a waterproof sheet 54 is formed on the inner surface of the blade member 26, and the waterproof sheet 54 is interposed on the inner surface in a state where the blade member 26 is moved toward the indoor side to close the opening portion 22. In the ventilation path S (outdoor side path S2) formed between the openings 22. Thereby, even if it is subjected to wind and rain when the ventilation device 10 performs ventilation, for example, the waterproof sheet 54 can be used to catch rainwater. As a result, it is possible to suppress the penetration of rainwater or the like into the indoor side.

In the ventilator 10, the blade member 26 and the outer panel 25 are respectively supported by one side portion of the opening portion 22, and the respective opening directions to the outside are the same. Therefore, the blade member 26 and the outer side panel 25 are opened in the same direction from the outer wall surface of the building, for example, so that the building wind or the like blown along the outer wall surface can be introduced more efficiently, and the ventilation efficiency can be further improved.

In the ventilating device 10, the blade member 26 always receives a load in the opening direction due to its own weight. Therefore, even if the size of the height, the width, and the like of the ventilator 10 are changed, the size of the blade member 26 is similarly changed, so that the weight increases and decreases, and the surface area that receives the wind pressure also increases and decreases. For example, in the case where the height dimension of the blade member 26 is increased, its own weight is increased, and its surface area is also increased, and in the case where the height dimension is reduced, its own weight is reduced, and its surface area is also reduced. Therefore, the increase or decrease of the load in the opening direction based on the self-weight (gravity) is proportional to the increase or decrease of the wind force capable of overcoming the self-weight. As a result, regardless of the size of the blade member 26, the opening area of the ventilating opening 62 is adjusted to a size corresponding to the outdoor wind force, so that the amount of ventilation air is maintained constant. As described above, even when the size of the blade member 26 is changed, the load in the opening direction of the blade member 26 based on the own weight is proportional to the pressure receiving area of the blade member 26 that receives the wind force. Therefore, compared with the conventional structure using the elastic body, the opening and closing operation of the blade member 26 with respect to the wind force is smoother, and it is not easy to cause a performance difference depending on the device size. Further, compared with a structure in which the blade member 26 is biased in the opening direction by using the elastic body, the manufacturing cost and the manufacturing efficiency can be improved, and the deterioration of the elastic body does not occur, so that durability can be ensured.

It is to be understood that the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the spirit and scope of the invention.
