換気扇は、住宅の台所に設置されて使用されることが多く、油煙又は埃の付着によって各シャッター板の動作が悪くならないように、各シャッター板と本体枠との間に若干の隙間を設けた構造となっている。したがって、隙間部分からの室外側の空気の流入及び光の侵入が問題となる。
Ventilation fans are often used in residential kitchens, and a slight gap is provided between each shutter plate and the body frame so that the operation of each shutter plate does not deteriorate due to adhesion of oily smoke or dust. It has a structure. Therefore, inflow of outdoor air from the gap portion and intrusion of light become a problem.
特許文献１に開示される換気扇は、本体枠と各シャッター板との重なりが無い上部に隙間が存在する。したがって、シャッター板と本体枠との隙間からの室外側空気の流入及び光の侵入を低減する余地がある。また、シャッター板が、回転軸の軸方向となる横方向に本体枠からはみ出てしまうことが容易に想定される。換気扇は、木枠を用いて住宅の壁の角穴に取り付けられることが多いため、本体枠からシャッター板がはみ出てしまうと、シャッター板と角穴内側面とが干渉し、シャッター板の動作不良でシャッターを開閉できなくなる恐れがある。
The ventilation fan disclosed in Patent Document 1 has a gap in the upper portion where the main body frame and each shutter plate do not overlap. Therefore, there is room for reducing the inflow of outdoor air and the intrusion of light from the gap between the shutter plate and the main body frame. Further, it is easily assumed that the shutter plate protrudes from the main body frame in the lateral direction that is the axial direction of the rotation axis. Ventilation fans are often installed in square holes on the walls of houses using wooden frames.If the shutter plate protrudes from the main body frame, the shutter plate interferes with the inner surface of the square hole, which may cause malfunction of the shutter plate. There is a risk that the shutter cannot be opened or closed.

The shutter plate 161 rotates around the rotation shaft 21 between the open position and the closed position. The shutter plate 161 is rotated upward around the rotation shaft 21 by the wind pressure of the ventilation flow generated by the fan 15 to be turned sideways to open the air path. The shutter plate 161 is self-weighted when the fan 15 stops. Rotate downward about the rotation axis 21 and turn downward to close the air passage.
図４は、実施の形態１に係る換気扇のシャッター板が開口を塞いだ状態を示す断面図である。図４は、シャッター板１６１が開口１１１を塞いだ状態を上下方向からみた断面を示している。シャッター板１６１は、本体枠１１の左右の縁である側枠部１１ａの端部１１ｅ同士の間隔Ｗ１よりも小さく、側枠部１１ａの内側面１１ｇから開口１１１の中央側に突出した前面部１１ｂ同士の間隔Ｗ２よりも大きい幅Ｗ３を持っている。シャッター板１６１が開口１１１を塞いだ状態にあるときに、シャッター板１６１の側端部１６ａは、本体枠１１の側部枠１１ａの内側面１１ｇから突出した前面部１１ｂに平行になって重なるため、本体枠１１とシャッター板１６１との隙間からの室外空気の流入及び光の侵入は生じにくくなっている。
FIG. 4 is a cross-sectional view showing a state where the shutter plate of the ventilation fan according to Embodiment 1 blocks the opening. FIG. 4 shows a cross section of the state in which the shutter plate 161 closes the opening 111 as viewed from above and below. The shutter plate 161 is smaller than the interval W1 between the end portions 11e of the side frame portion 11a which is the left and right edges of the main body frame 11, and the front surface portion 11b protruding from the inner side surface 11g of the side frame portion 11a toward the center side of the opening 111. The width W3 is larger than the interval W2. When the shutter plate 161 closes the opening 111, the side end portion 16a of the shutter plate 161 is overlapped in parallel with the front surface portion 11b protruding from the inner side surface 11g of the side frame 11a of the main body frame 11. Inflow of outdoor air and intrusion of light from the gap between the main body frame 11 and the shutter plate 161 are less likely to occur.
図５は、実施の形態１に係る換気扇の本体枠の上部での断面図である。図６は、実施の形態１に係る換気扇の本体枠の上下方向の中央部での断面図である。図７は、実施の形態１に係る換気扇の本体枠の下部での断面図である。本体枠１１は、開口１１１の上側の縁の端部から下方向に突出する上端部屈曲部１１ｃと、開口１１１の下側の縁の端部から上方向に突出する下端部屈曲部１１ｆと、開口１１１の左右の縁である側枠部１１ａの内側面１１ｇから開口１１１の中央側に突出した前面部１１ｂとを有する。シャッター板１６１は、開口１１１を塞ぐシャッター面１６１ａと、シャッター面１６１ａが開口１１１を塞いだ状態において、上端１６１ｂがシャッター面１６１ａよりも本体枠１１の他端側に位置するようにクランク状に屈曲した上端部１６ｂと、シャッター面１６１ａが開口を塞いだ状態において、下端１６１ｃが本体枠１１の他端側に位置するように本体枠１１の他端側に屈曲した下端部１６ｃとを有する。
FIG. 5 is a cross-sectional view of the upper part of the main body frame of the ventilation fan according to the first embodiment. FIG. 6 is a cross-sectional view of the center frame of the main body frame of the ventilation fan according to Embodiment 1 in the vertical direction. FIG. 7 is a cross-sectional view of the lower part of the main body frame of the ventilation fan according to the first embodiment. The main body frame 11 includes an upper end bent portion 11c that protrudes downward from an end of the upper edge of the opening 111, a lower end bent portion 11f that protrudes upward from an end of the lower edge of the opening 111, It has a front surface portion 11 b that protrudes from the inner side surface 11 g of the side frame portion 11 a that is the left and right edges of the opening 111 to the center side of the opening 111. The shutter plate 161 is bent in a crank shape so that the shutter surface 161a that closes the opening 111 and the upper end 161b is located on the other end side of the main body frame 11 with respect to the shutter surface 161a in a state where the shutter surface 161a closes the opening 111. The upper end portion 16b and the lower end portion 16c bent to the other end side of the main body frame 11 so that the lower end 161c is located on the other end side of the main body frame 11 when the shutter surface 161a closes the opening.
図５に示すように、シャッター板１６１は、上端部１６ｂがクランク状に曲げられており、シャッター１６を閉じた時、シャッター板１６１の上端部１６ｂが本体枠１１の上端部屈曲部１１ｃよりも本体枠１１の他端側に入り込む。すなわち、シャッター板１６１が開口１１１を塞いだ状態において、上端部１６ｂは、上端部屈曲部１１ｃよりも本体枠１１の他端側に配置される。したがって、本体枠１１の上端部屈曲部１１ｃとシャッター板１６１との隙間からの室外側空気の流入及び光の侵入は生じにくくなっている。
As shown in FIG. 5, the shutter plate 161 has an upper end portion 16 b bent in a crank shape. When the shutter 16 is closed, the upper end portion 16 b of the shutter plate 161 is more than the upper end bent portion 11 c of the main body frame 11. It enters into the other end side of the main body frame 11. That is, in a state where the shutter plate 161 closes the opening 111, the upper end portion 16b is disposed on the other end side of the main body frame 11 with respect to the upper end portion bent portion 11c. Therefore, the inflow of outdoor air and the entry of light from the gap between the upper end bent portion 11c of the main body frame 11 and the shutter plate 161 are less likely to occur.
また、図６に示すように、シャッター板の上端部１６ｂは、上方に位置する別のシャッター板１６１の下端部１６ｃよりも室内側に入り込む。すなわち、上下方向に配列された複数のシャッター板１６１は、開口１１１を塞いだ状態において、下側のシャッター板１６１の上端部１６ｂは、上側のシャッター板１６１の下端部１６ｃよりも本体枠１１の他端側に配置される。したがって、シャッター板１６１同士の隙間からの室外側空気の流入及び光の侵入は生じにくくなっている。
Further, as shown in FIG. 6, the upper end portion 16b of the shutter plate enters the indoor side from the lower end portion 16c of another shutter plate 161 positioned above. That is, in the state where the plurality of shutter plates 161 arranged in the vertical direction block the opening 111, the upper end portion 16b of the lower shutter plate 161 is closer to the lower end portion 16c of the upper shutter plate 161 than the lower end portion 16c of the upper shutter plate 161. Arranged on the other end side. Therefore, inflow of outdoor air and intrusion of light from the gap between the shutter plates 161 are less likely to occur.
図７に示すように、本体枠１１は、下端部屈曲部１１ｆにリブ１１ｄが設けられている。シャッター板１６１の下端部１６ｃは、リブ状になっており、シャッター板１６１が閉じると、下端部１６ｃは、下端部屈曲部１１ｆが本体枠１１の他端側に隣接するように下端部屈曲部１１ｆと重なる。換言すると、シャッター板１６１の下端部１６ｃは、シャッター面１６１ａが開口１１１を塞いだ状態において、下端１６１ｃが本体枠１１の他端側に位置するように、本体枠１１の他端側に屈曲し、シャッター面１６１ａとの間で鈍角をなす傾斜面１６２を備えている。また、下端部屈曲部１１ｆは、本体枠１１の他端側と逆側に突出するリブ１１ｄを備えている。したがって、本体枠１１の下端部屈曲部１１ｆとシャッター板１６１との隙間からの室外側空気の流入及び光の侵入は生じにくくなっている。シャッター板１６１の下端部１６ｃは、シャッター板１６１に対して鈍角の角度αを有する傾斜面１６２を備えた形状となっているため、滞留が生じにくく風路の圧力損失となりにくい。
As shown in FIG. 7, the main body frame 11 is provided with a rib 11d at a lower end bent portion 11f. The lower end portion 16c of the shutter plate 161 has a rib shape. When the shutter plate 161 is closed, the lower end portion 16c has a lower end bent portion so that the lower end bent portion 11f is adjacent to the other end side of the main body frame 11. It overlaps with 11f. In other words, the lower end portion 16c of the shutter plate 161 is bent toward the other end side of the main body frame 11 so that the lower end 161c is positioned on the other end side of the main body frame 11 in a state where the shutter surface 161a closes the opening 111. And an inclined surface 162 that forms an obtuse angle with the shutter surface 161a. Further, the lower end bent portion 11 f includes a rib 11 d that protrudes on the opposite side to the other end side of the main body frame 11. Therefore, inflow of outdoor air and intrusion of light from the gap between the lower end bent portion 11f of the main body frame 11 and the shutter plate 161 are difficult to occur. Since the lower end portion 16c of the shutter plate 161 has a shape including an inclined surface 162 having an obtuse angle α with respect to the shutter plate 161, it is difficult for stagnation to occur and the pressure loss of the air passage is unlikely to occur.
図８は、実施の形態１に係る換気扇の本体枠の一端側を示す斜視図である。図４及び図８に示すように、換気扇１の本体枠１１は、本体枠１１の側部枠１１ａの内側面１１ｇから前面部１１ｂが突出し、側部枠１１ａの端面と前面部１１ｂとの間に段差が生じていることにより、シャッター板１６１が下向きの閉じ位置にあるときに、シャッター板１６１が本体枠１１から横にはみ出さないようになっている。これにより、シャッター板１６１が本体枠１１から横にはみ出し、シャッター板１６１と取り付け時の壁穴３１の内側面との干渉により、シャッター１６が開かない又はシャッター１６が閉じないといった動作不良が発生することを防止できる。なお、前面部１１ｂと端面１１ｅとの段差を、シャッター板１６１の板厚よりも大きくすることで、シャッター１６を下にして換気扇１を置いた際に、シャッター板１６１に荷重がかかって回動軸２１が破損することを防止できる。
FIG. 8 is a perspective view showing one end side of the main body frame of the ventilation fan according to the first embodiment. As shown in FIGS. 4 and 8, the main body frame 11 of the ventilation fan 1 has a front surface portion 11b protruding from the inner side surface 11g of the side frame 11a of the main body frame 11, and between the end surface of the side frame 11a and the front surface portion 11b. Due to the difference in level, the shutter plate 161 does not protrude laterally from the main body frame 11 when the shutter plate 161 is in the downwardly closed position. As a result, the shutter plate 161 protrudes laterally from the main body frame 11, and malfunctions such as the shutter 16 not opening or closing due to interference between the shutter plate 161 and the inner surface of the wall hole 31 at the time of attachment occur. Can be prevented. The step between the front surface portion 11b and the end surface 11e is made larger than the thickness of the shutter plate 161, so that when the ventilation fan 1 is placed with the shutter 16 down, the shutter plate 161 is loaded and rotated. It is possible to prevent the shaft 21 from being damaged.
図９は、実施の形態１に係る換気扇のシャッター板の斜視図である。図９に示すように、シャッター板１６１の裏面両側端部には、リブ１６ｄが設けられている。換言すると、シャッター面には、シャッター板１６１が開口を塞いだ状態において、本体枠１１の開口の左右の縁である側枠部１１ａに沿うリブ１６ｄを設けられている。したがって、シャッター板１６１は換気流を受けやすい構造になっており、シャッター１６は、換気流の風圧によって容易に開く。
FIG. 9 is a perspective view of the shutter plate of the ventilation fan according to the first embodiment. As shown in FIG. 9, ribs 16 d are provided at both ends of the rear surface of the shutter plate 161. In other words, the rib 16d is provided on the shutter surface along the side frame portion 11a which is the left and right edges of the opening of the main body frame 11 in a state where the shutter plate 161 closes the opening. Accordingly, the shutter plate 161 has a structure that easily receives the ventilation flow, and the shutter 16 is easily opened by the wind pressure of the ventilation flow.
実施の形態１に係る換気扇１では、本体枠１１は、開口１１１の上側の縁の端部から下方向に突出する上端部屈曲部１１ｃと、開口１１１の下側の縁の端部から上方向に突出する下端部屈曲部１１ｆと、開口１１１の左右の縁のである側枠部１１ａの内側面１１ｇから開口１１１の中央側に突出する前面部１１ｂとを有する。また、シャッター板１６１は、開口１１１を塞ぐシャッター面１６１ａと、シャッター面１６１ａが開口１１１を塞いだ状態において、上端１６１ｂが本体枠１１の他端側に位置するようにクランク状に屈曲した上端部１６ｂとを有し、本体枠１１の左右の縁である側枠部１１ａ同士の間隔よりも小さく、前面部１１ｂ同士の間隔よりも大きい幅を持っている。シャッター板１６１が開口１１１を塞いだ状態において、上端部１６ｂは、上端部屈曲部１１ｃよりも本体枠１１の他端側に配置され、シャッター板１６１の下端部１６ｃは、下端部屈曲部１１ｆが本体枠１１の他端側に隣接するように下端部屈曲部１１ｆと重なる。したがって、シャッター板１６１と本体枠１１との隙間からの室外側空気の流入及び非開の侵入を低減することができる。
In the ventilation fan 1 according to the first embodiment, the main body frame 11 includes the upper end bent portion 11c that protrudes downward from the edge of the upper edge of the opening 111, and the upward direction from the edge of the lower edge of the opening 111. A bottom end bent portion 11f that projects to the center of the opening 111 from the inner side surface 11g of the side frame portion 11a that is the left and right edges of the opening 111. The shutter plate 161 includes a shutter surface 161a that closes the opening 111, and an upper end portion that is bent in a crank shape so that the upper end 161b is positioned on the other end side of the main body frame 11 in a state where the shutter surface 161a closes the opening 111. 16b, which is smaller than the interval between the side frame portions 11a which are the left and right edges of the main body frame 11, and larger than the interval between the front surface portions 11b. In a state in which the shutter plate 161 closes the opening 111, the upper end portion 16b is disposed on the other end side of the main body frame 11 with respect to the upper end portion bent portion 11c, and the lower end portion 16c of the shutter plate 161 has the lower end portion bent portion 11f. It overlaps with the lower end bent portion 11f so as to be adjacent to the other end side of the main body frame 11. Therefore, inflow of outdoor air from the gap between the shutter plate 161 and the main body frame 11 and non-open intrusion can be reduced.
