The entire piping section 25 can be concealed regardless of whether the wall 7 formed with the opening 3 is on the right side or the left side of the centrifugal fan type ventilation fan 2 . That is, regardless of whether the wall 7 having the opening 3 is on the right side or the left side of the centrifugal fan type ventilator 2, the entire pipe section 25 can be concealed by the same ventilator pipe concealing member 19. can.

したがって、換気扇システム１００では、開口３が形成された壁７が遠心送風機型換気扇２に向かって右側または左側のどちらに存在するかによって、配管部２５を隠蔽する換気扇用配管隠蔽部材を個別に用意し、選択する必要がない。 Therefore, in the ventilating fan system 100, depending on whether the wall 7 having the opening 3 is on the right side or the left side of the centrifugal fan type ventilating fan 2, a ventilating fan pipe concealing member for concealing the pipe portion 25 is individually prepared. and you don't have to choose.

図１８は、実施の形態１における側方隠蔽部材２１と吊戸２２と遠心送風機型換気扇２との奥行方向の位置関係を示す側面図である。吊戸２２は、遠心送風機型換気扇２を挟んで壁７と反対側において遠心送風機型換気扇２と隣り合わせに設けられ、台所の調理器具等が収納される収納部である。 FIG. 18 is a side view showing the positional relationship in the depth direction between the side shielding member 21, the hanging door 22, and the centrifugal fan type ventilation fan 2 according to the first embodiment. The hanging door 22 is provided adjacent to the centrifugal fan type ventilation fan 2 on the opposite side of the wall 7 with the centrifugal fan type ventilation fan 2 interposed therebetween, and is a storage section for storing kitchen utensils and the like.

側方隠蔽部材２１の奥行寸法Ｄ１は、吊戸２２の奥行寸法Ｄ２と同一とされており、具体的には４００ｍｍである。換気扇用配管隠蔽部材１９の据付手順を、先に側方隠蔽部材２１を取付け、次に上方隠蔽部材２０を取り付ける手順とすると、吊戸２２と側方隠蔽部材２１との奥行方向の位置が、墨出し作業等することなく自然と予め決めた位置に合致するようになる。 The depth dimension D1 of the side shielding member 21 is the same as the depth dimension D2 of the hanging door 22, specifically 400 mm. Assuming that the procedure for installing the ventilation fan pipe shielding member 19 is to first attach the side shielding member 21 and then attach the upper shielding member 20, the depth direction positions of the hanging door 22 and the side shielding member 21 are It comes to naturally match the predetermined position without marking work or the like.

側方隠蔽部材２１は、台所の後ろの壁７２との間に、予め決められた厚さの緩衝材などの部材を介して配置される。側方隠蔽部材２１は、側方隠蔽部材２１の奥行寸法Ｄ１と吊戸２２の奥行寸法Ｄ２とが同一とされ、適正な位置に配置されることで、奥行方向の位置が吊戸２２の奥行方向の位置と合致する。すなわち、側方隠蔽部材２１は、側方隠蔽部材２１の奥行寸法Ｄ１と吊戸２２の奥行寸法Ｄ２とが同一とされ、適正な位置に配置されることで、吊戸２２の正面と側方隠蔽部材２１の正面２１５との、奥行方向の位置が同じになる。 The side shielding member 21 is placed between the back wall 72 of the kitchen and a member such as a cushioning material having a predetermined thickness. The side concealing member 21 has the same depth dimension D1 of the side concealing member 21 and the depth dimension D2 of the hanging door 22, and is arranged at an appropriate position so that the position in the depth direction matches the depth of the hanging door 22. Match the position of the direction. That is, the side shielding member 21 has the same depth dimension D1 of the side shielding member 21 and the depth dimension D2 of the hanging door 22, and is arranged at an appropriate position, so that the front side and the side side of the hanging door 22 are arranged. The position in the depth direction is the same as the front face 215 of the concealing member 21 .

その後、上方隠蔽部材２０を側方隠蔽部材２１に取り付けることにより、上方隠蔽部材２０の奥行き方向の位置が、適正な位置に配置される。ここで、上方隠蔽部材２０は、側方隠蔽部材２１に一部が重なった状態で固定されるため、上方隠蔽部材２０の正面２１５と側方隠蔽部材２１の正面２０８とは、奥行き方向の位置がわずかに異なる状態となるが、ほぼ合致した状態となる。吊戸２２と、側方隠蔽部材２１と、上方隠蔽部材２０との奥行方向の位置をあらかじめ合致させた方が良いのは、台所の意匠性を向上させるためである。 After that, by attaching the upper shielding member 20 to the side shielding members 21, the position of the upper shielding member 20 in the depth direction is arranged at an appropriate position. Here, since the upper shielding member 20 is fixed in a state in which it partially overlaps with the side shielding member 21, the front surface 215 of the upper shielding member 20 and the front surface 208 of the side shielding member 21 are positioned in the depth direction. are in a slightly different state, but they are in a substantially matched state. The reason why the positions of the hanging door 22, the side shielding member 21, and the upper shielding member 20 in the depth direction should be matched in advance is to improve the design of the kitchen.
