JP 2007-170107 A

  The window device of the above-mentioned patent document 1 has a poor appearance because the joint between the frame of the ventilation device and the frame of the sash window can be seen from the room. In addition, since the entire panel on the indoor side of the ventilator and the entire ventilator fan chamber are above the joint, the height of the entire window device tends to increase. If the height of the building window is constant, the height of the window sash or ventilator must be reduced. If the height of the ventilation device is reduced, the storage space for the ventilation fan is reduced, and the ventilation fan must be reduced.

In order to solve the above problems, the present invention is a ventilation device with a window provided on the upper side of a sash window, separate from the sash window,
A ventilation fan unit including a ventilation fan;
A frame having an upper frame and a lower frame and a pair of vertical frames;
A cover member that covers the ventilation fan unit from the indoor side so as to form a housing room for the ventilation fan unit between the frame body,
The lower frame is overlaid on the upper side of the sash upper frame in the sash window, and the bottom portion of the cover member is located below the seam on the indoor side of the lower frame and the sash upper frame. Features.
According to this characteristic configuration, the joint between the ventilation fan frame body and the sash window frame can also be covered from the indoor side by the cover member that covers the ventilation fan from the indoor side. Therefore, even if the ventilation fan frame is separate from the sash window frame, the joints thereof can be prevented from being exposed to the room, and the aesthetic appearance of the room can be avoided. Moreover, since the lower part of the cover member and the storage chamber overlaps in the height direction with the joint part (the peripheral part including the seam) between the ventilation fan frame and the sash window frame, the height dimension of the entire window device Can be suppressed. Alternatively, the accommodation chamber can be made large and the ventilation fan can be sufficiently accommodated.

And a connecting member that connects the lower frame to the sash upper frame, and the connecting member covers the seam by straddling the indoor side surface of the lower frame to the indoor side surface of the sash upper frame. It is preferable.
With the connecting member, the lower frame of the ventilation fan frame and the upper frame of the sash can be firmly connected. In addition, the joint can be hidden by the connecting member, and the connecting member can be covered from the indoor side by the cover member. Therefore, it is possible to avoid the appearance of the room from being damaged by the joint and the connecting member. Since the lower part of the cover member and the storage chamber overlaps with the connecting member in the height direction, an increase in the height dimension of the entire window device can be suppressed, or the storage chamber can be widened.
The whole of the connecting member may overlap the lower part of the cover member and the storage chamber in the height direction, and only the upper part of the connecting member above the middle in the vertical direction is below the cover member and the storage chamber. It may overlap with the side portion in the height direction.
The connecting member preferably extends from the vicinity of one end portion in the longitudinal direction of the lower frame to the vicinity of the other end portion, or preferably extends over substantially the entire length in the longitudinal direction of the lower frame. Accordingly, the connecting member can cover most of the seam.

The storage chamber is opened downward, and a filter unit is provided in the opening.The connecting member is provided with a shaft support portion that rotatably supports the filter unit in the up and down direction. It is preferable that a latching portion for releasably latching the filter unit is provided.
According to this configuration, the filter unit can be made inconspicuous. During maintenance, when the hook of the filter unit is released, the filter unit can be rotated downward about the shaft support portion. As a result, the filter can be easily removed or replaced. Further, the storage chamber can be easily opened, and the storage chamber and the exhaust fan can be easily cleaned and inspected. Furthermore, the number of parts and the number of assembling steps can be reduced by integrally providing the shaft support for the filter unit on the connecting member that connects the frames.

It is preferable that the shaft support portion is disposed at a lower portion than a portion of the connecting member that covers the joint.
Thus, the portion of the connecting member that covers the joint can be reliably covered with the cover member and the filter unit.

  According to the present invention, even if the ventilation fan frame is separate from the sash window frame, the joints thereof can be prevented from being exposed to the room, and the appearance of the room can be prevented from being impaired. Moreover, the ventilation fan accommodation room can be enlarged. Or the increase in the height dimension of the whole window apparatus can be suppressed.

The convex edge portion 53 has an inverted L-shaped cross section, protrudes upward from the filter installation plate 51, and extends left and right (in a direction orthogonal to the paper surface of FIG. 3). End frames 52 are attached to the left and right ends of the filter installation plate 51, respectively. The end frame 52 is made of resin, extends along the left and right ends of the filter installation plate 51, and protrudes above the filter installation plate 51.

  A planar or sheet-like filter 59 is placed on the upper surface of the filter installation plate 51. The edges on the outdoor side and the indoor side of the filter 59 are directed to the convex edge portions 53 and 53. The left and right edges of the filter 59 are addressed to the end frames 52 and 52.

The filter unit 50 is attached to the window device 1 as follows.
As shown in FIG. 3, a rotary shaft 58 is integrally provided at the end of the filter installation plate 51 on the outdoor side (left side in FIG. 3). The rotating shaft 58 has a circular cross section and extends to the left and right (in the direction orthogonal to the plane of FIG. 3). A shaft support 63 is integrally provided on the base 61 of the connecting member 60. The shaft support 63 is disposed below the portion of the connecting member 60 that covers the joint 19, has a C-shaped cross section, and extends left and right (horizontal direction). A rotation shaft 58 is fitted on the shaft support 63 so as to be rotatable around its own axis. Thus, the shaft support 63 supports the filter unit 50 so as to be rotatable up and down. In other words, the outdoor end of the filter unit 50 is rotatably supported by the frame members 10 and 20 via the connecting member 60.

  As shown in FIG. 3, a locking lever 55 is provided at the end of the end frame 52 on the indoor side (right side in FIG. 3) via a connecting portion 54. The connecting portion 54 and the locking lever 55 are the same body as the end frame 52. The connecting portion 54 has a downward semicircular arc shape, and protrudes from the end frame 52 in the indoor direction (right in FIG. 3). The central portion of the locking lever 55 is connected to the protruding end of the connecting portion 54.

As shown in FIGS. 2 and 3, the cover member 40 is provided with a latch member 44 (a latch portion). The latch member 44 is made of a rod-like and irregularly shaped aluminum mold that extends in the left-right direction (a direction orthogonal to the paper surface of FIG. 3). The latch member 44 is disposed near the bottom of the storage chamber 20b and the vertical wall 46. Both ends in the extending direction of the latch member 44 are supported by the end plate 42 by screws. Further, a rib 47 is provided on the inner surface near the lower end of the vertical wall 46. The rib 47 extends to the left and right, protrudes from the vertical wall 46 in the outdoor direction (left in FIG. 3), and hits the side of the latch member 44. Insertion holes 47 a and 47 a are provided near both ends in the extending direction of the rib 47. The latching claw 56 is inserted between the latching member 44 and the vertical wall 46 and passed through the insertion hole 47a, and is releasably latched on the upper end portion of the latching member 44. In other words, the latch member 44 (latching portion) latches the filter unit 50 so as to be releasable. Thus, the filter unit 50 is attached to the bottom of the cover member 40 substantially horizontally.
In this embodiment, the filter unit 50 is disposed to be slightly inclined upward as it goes in the indoor direction (right in FIG. 3).

Operation | movement of the sash window apparatus 1 with a ventilation function comprised as mentioned above is demonstrated.
When the ventilating fan 31 is driven, the air in the room 3 passes through the indoor vent 51 a, dust is removed by the filter 59, enters the housing chamber 20 b, and is sucked into the ventilating fan 31. This air is discharged from the sending section 32 to the ventilation chamber 20a, and is sent to the outside (outdoor) through the outdoor vent 26b. Along with this, outside air enters the room 3 from another opening of the building. Thereby, the atmosphere in the room 3 can be ventilated.

When the filter 59 is cleaned or replaced, the lever portion 57 is pushed in the outdoor direction (left in FIG. 3). Then, the connecting portion 54 is elastically deformed, and the entire locking lever 55 rotates a little around the connecting portion 54. As a result, the latching claw 56 is tilted toward the vertical wall 46 and detached from the latching member 44, and the latched state can be released. Therefore, the end on the lever portion 57 side of the filter unit 50 becomes free, and the filter unit 50 can be rotated downward about the rotation shaft 58. As a result, as shown in FIG. 5, the filter unit 50 can hang downward or tilt downward from the rotating shaft 58, and the filter 59 on the installation plate 51 can be exposed to the room 3. Therefore, the filter 59 can be easily removed or replaced.
Furthermore, when maintaining the ventilation fan 31, the engagement between the hook member 43 and the suspension support portion 22d is released, and the cover member 40 is pulled out in the indoor direction (right in FIG. 3). Since the ventilation fan unit 30 is not fixed to the cover member 40, the cover member 40 can be easily removed. The ventilation fan 31 is exposed to the room 3 by removing the cover member 40. Thereby, the ventilation fan 31 can be easily cleaned or inspected.

In the sash window device 1 with the ventilation function configured as described above, the connecting member 60 covers the joint 19, and the frame connecting portion 62 of the connecting member 60 is covered from the indoor side by the cover member 40. Therefore, not only the joint 19 but also the frame connecting portion 62 can be prevented from being exposed to the room 3, and the sash window device 1 can be secured.
Since the connecting member 60 extends over substantially the entire length of the frames 12 and 23, most of the seam 19 can be covered.
Further, since the shaft support portion 63 is provided below the frame connecting portion 62 (the portion covering the joint 19), the filter unit 50 can be disposed below the frame connecting portion 62, and the frame connecting portion 62 is attached to the filter unit 50. Can be covered from below.
Furthermore, since the indoor vent 51a faces downward, it is not conspicuous and the aesthetics can be further improved.

Further, the lower part (bottom part) of the cover member 40 and the storage chamber 20b overlaps with the frame connecting part 62, that is, the joint part of the frames 23 and 12 (the peripheral part including the joint 19) in the height direction. As a result, the storage chamber 20b can be enlarged and the ventilation fan 31 can be stored sufficiently. Or the increase in the height dimension of the window apparatus 1 whole can be suppressed.
Furthermore, by integrally configuring the frame connecting portion 62 that connects the frames 12 and 23 and the shaft support portion 63 that supports the filter unit 50, the number of parts and the number of assembly steps can be reduced.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the lower end portion (bottom portion) of the cover member 40 may be located below the shaft support portion 63, and may be located below the base portion 61.
The frame connecting portion 62 does not necessarily have to be entirely covered in the extending direction of the joint 19, and the frame connecting portion 62 may not be partially covered by the joint 19. Alternatively, the frame connecting part 62 may be omitted. Even in such a case, the cover member 40 can cover the joint 19 so that it cannot be seen from the room.
The frame connecting part 62 and the shaft support part 63 may be separate members.
From the viewpoint of facilitating maintenance of the filter unit 50, it is sufficient that the filter unit 50 has a rotary structure, and the bottom portion of the cover member 40 may not be positioned below the joint 19, and the frame connecting portion 62. May not be covered with the cover member 40, and the frame connecting portion 62 may be omitted. Further, the frames 12 and 14 of the sash window 10 and the frames 23 and 24 of the ventilation device 20 do not have to be separate. The left and right ends of the filter unit 50 may be releasably hooked on the cover member 40.

  The present invention can be applied, for example, to a ventilation device attached to a sash window of a house.
