The air filter holding guide rail 13 is a rail extending in the axial direction X of the heat exchanger 8. The air filter holding guide rail 13 is a U-shaped guide rail having a groove that is open on the bottom surface 52 side and into which the upper end of the air filter 12 is fitted. The air filter holding guide rail 13 serves to transfer air from the space other than the air filter 12 from the space upstream of the air filter 12 to the space downstream of the air filter 12 in the air supply passage 5A. In order to suppress the flow, a sealing member 18 parallel to the elastic top surface 51 is attached to the inner surface of the groove. 1 to 3, the air filter 12 is not shown.
　このように構成された熱交換型換気装置１００において、エアフィルター１２の外装箱５への取り付け時には、まず、図５に示すように、第１可動ガイドレール１１３を上方側すなわち天面５１側に移動させるとともに、第２可動ガイドレール１１４を下方側すなわち底面５２側に移動させて配置する。 In the heat exchange type ventilator 100 configured as described above, when the air filter 12 is attached to the outer box 5, first, as shown in FIG. 5, the first movable guide rail 113 is placed on the upper side, that is, on the top surface 51 side. At the same time, the second movable guide rail 114 is moved to the lower side, that is, the bottom surface 52 side, and is arranged.
　これにより、図５に示すように、第１可動ガイドレール１１３に貼り付けられたシール部材１８および第１可動ガイドレール１１３と全熱交換素子８０の第３熱交換器枠２２３との間、および第２可動ガイドレール１１４に貼り付けられたシール部材１８および第２可動ガイドレール１１４と全熱交換素子８０の第４熱交換器枠２２４との間を離した状態で、前面５３に形成されたメンテナンス開口１７から熱交換器８を外装箱５内へと容易にスライドさせて挿入することができる。この場合、第１可動ガイドレール１１３に貼り付けられたシール部材１８および第１可動ガイドレール１１３と全熱交換素子８０の第３熱交換器枠２２３との間にクリアランスが設けられており、第２可動ガイドレール１１４に貼り付けられたシール部材１８および第２可動ガイドレール１１４と全熱交換素子８０の第４熱交換器枠２２４との間にクリアランスが設けられているため、メンテナンス開口１７から外装箱５内への熱交換器８の挿入が容易になる。 Thereby, as shown in FIG. 5, between the seal member 18 attached to the first movable guide rail 113 and between the first movable guide rail 113 and the third heat exchanger frame 223 of the total heat exchange element 80, and The sealing member 18 attached to the second movable guide rail 114 and the second movable guide rail 114 are formed on the front surface 53 in a state where the second movable guide rail 114 is separated from the fourth heat exchanger frame 224 of the total heat exchange element 80. The heat exchanger 8 can be easily slid and inserted into the exterior box 5 from the maintenance opening 17. In this case, a clearance is provided between the seal member 18 attached to the first movable guide rail 113 and the third heat exchanger frame 223 of the first movable guide rail 113 and the total heat exchange element 80, (2) Since a clearance is provided between the second movable guide rail 114 and the fourth heat exchanger frame 224 of the total heat exchange element 80, the seal member 18 attached to the movable guide rail 114 and the maintenance opening 17 Insertion of the heat exchanger 8 into the outer box 5 is facilitated.
　すなわち、第１可動ガイドレール１１３は、第１可動ガイドレール１１３に貼り付けられたシール部材１８の厚みと第３熱交換器枠２２３の幅との合計よりも大きい溝幅を有する。第２可動ガイドレール１１４は、第２可動ガイドレール１１４に貼り付けられたシール部材１８の厚みと第４熱交換器枠２２４の幅との合計よりも大きい溝幅を有する。 That is, the first movable guide rail 113 has a groove width larger than the sum of the thickness of the seal member 18 attached to the first movable guide rail 113 and the width of the third heat exchanger frame 223. The second movable guide rail 114 has a groove width larger than the sum of the thickness of the seal member 18 attached to the second movable guide rail 114 and the width of the fourth heat exchanger frame 224.
　また、この状態で、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３に貼り付けられたシール部材１８との間に、エアフィルター１２の縦方向の幅寸法よりも大きい寸法のクリアランスが設けられる。これにより、前面５３に形成されたメンテナンス開口１７からエアフィルター１２を外装箱５内へと容易にスライドさせて挿入することができる。エアフィルター１２の縦方向の幅寸法は、エアフィルター１２における上下方向の寸法であり、高さ寸法である。 In this state, a clearance having a size larger than the vertical width of the air filter 12 is provided between the second movable guide rail 114 and the seal member 18 attached to the air filter holding guide rail 13. . Thereby, the air filter 12 can be easily slid and inserted into the exterior box 5 from the maintenance opening 17 formed in the front surface 53. The vertical width dimension of the air filter 12 is a vertical dimension of the air filter 12 and a height dimension.
　この場合、エアフィルター保持ガイドレール１３に貼り付けられたシール部材１８と第２可動ガイドレール１１４との間にエアフィルター１２の縦方向の幅寸法よりも大きい寸法のクリアランスを設けられているため、メンテナンス開口１７から外装箱５内への熱交換器８の挿入が容易になる。また、エアフィルター保持ガイドレール１３にシール部材１８が貼り付けられていない場合には、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３の内底面との間に、エアフィルター１２の縦方向の幅寸法よりも大きい寸法のクリアランスが設けられることになる。 In this case, a clearance having a size larger than the vertical width of the air filter 12 is provided between the seal member 18 attached to the air filter holding guide rail 13 and the second movable guide rail 114. Insertion of the heat exchanger 8 from the maintenance opening 17 into the exterior box 5 is facilitated. When the seal member 18 is not attached to the air filter holding guide rail 13, the vertical direction of the air filter 12 is located between the second movable guide rail 114 and the inner bottom surface of the air filter holding guide rail 13. A clearance having a dimension larger than the width dimension will be provided.
　その後、図６に示すように、第１可動ガイドレール１１３を下方側すなわち底面５２側に移動させた位置に固定し、第１可動ガイドレール１１３に貼り付けられたシール部材１８を第３熱交換器枠２２３の天面５１側の側面に押し当てる。この結果、第１可動ガイドレール１１３がシール部材１８を介して第３熱交換器枠２２３を下方に押圧する。さらに、第２可動ガイドレール１１４を上方側すなわち天面５１側に移動させた位置に固定し、第２可動ガイドレール１１４に貼り付けられたシール部材１８を第４熱交換器枠２２４の底面５２側の側面に押し当てる。この結果、第２可動ガイドレール１１４がシール部材１８を介して第４熱交換器枠２２４を上方に押圧する。 Thereafter, as shown in FIG. 6, the first movable guide rail 113 is fixed at a position moved downward, that is, toward the bottom surface 52, and the seal member 18 attached to the first movable guide rail 113 is subjected to the third heat exchange. It is pressed against the side surface on the top surface 51 side of the container frame 223. As a result, the first movable guide rail 113 presses the third heat exchanger frame 223 downward via the seal member 18. Further, the second movable guide rail 114 is fixed at a position moved upward, that is, toward the top surface 51, and the seal member 18 attached to the second movable guide rail 114 is attached to the bottom surface 52 of the fourth heat exchanger frame 224. On the side. As a result, the second movable guide rail 114 presses the fourth heat exchanger frame 224 upward via the seal member 18.
　これにより、熱交換器８には、図６に円形矢印で示す一方向側への回転力Ｆが付与され、第１固定ガイドレール１１１に貼り付けられたシール部材１８に第１熱交換器枠２２１の外気側側面５６側の側面が押し当てられ、第２固定ガイドレール１１２に貼り付けられたシール部材１８に第２熱交換器枠２２２の内気側側面５５の側面が押し当てられる。第１固定ガイドレール１１１が天面５１に固定されており、第２固定ガイドレール１１２が底面５２に固定されている。この結果、熱交換器８の四隅の角部の熱交換器枠２２の全てが複数のガイドレール１１に押し当てられ、熱交換器８が外装箱５内で複数のガイドレール１１によって支持され、固定される。 As a result, a rotational force F in one direction indicated by a circular arrow in FIG. 6 is applied to the heat exchanger 8, and the first heat exchanger frame is attached to the seal member 18 attached to the first fixed guide rail 111. 221 is pressed against the outside air side surface 56 side, and the side surface of the inside air side surface 55 of the second heat exchanger frame 222 is pressed against the seal member 18 attached to the second fixed guide rail 112. The first fixed guide rail 111 is fixed to the top surface 51, and the second fixed guide rail 112 is fixed to the bottom surface 52. As a result, all of the heat exchanger frames 22 at the four corners of the heat exchanger 8 are pressed against the plurality of guide rails 11, and the heat exchanger 8 is supported by the plurality of guide rails 11 in the outer box 5, Fixed.
　また、第２可動ガイドレール１１４がエアフィルター１２の下面、すなわち底面５２側の端面に押し当てられることにより、エアフィルター１２は、天面５１側に押圧された状態で、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３との間にエアフィルター１２が保持される。ここで、回転力Ｆによって第２可動ガイドレール１１４がエアフィルター１２に押し当てられることにより、エアフィルター１２の縦方向の幅寸法に個体差があった場合、および第２可動ガイドレール１１４の縦方向の幅寸法に個体差があった場合でも、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３との間の隙間の発生を抑制してエアフィルター１２を保持することができる。これにより、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３との間から空気が漏えいして室内へ塵埃および虫が侵入することを抑制できる。このように、エアフィルター１２を天面５１側に押圧した状態で固定することにより、エアフィルター１２の保持構造における隙間を減らすことが可能であり、給気通風路５Ａにおいてエアフィルター１２によって区画されるエアフィルター１２よりも上流側の空間からエアフィルター１２よりも下流側の空間へのエアフィルター１２以外での空気の流れを抑制することができる。 Further, the second movable guide rail 114 is pressed against the lower surface of the air filter 12, that is, the end surface on the bottom surface 52 side, so that the air filter 12 is pressed against the top surface 51 side. The air filter 12 is held between the air filter holding guide rail 13 and the air filter holding guide rail 13. Here, when the second movable guide rail 114 is pressed against the air filter 12 by the rotational force F, there is an individual difference in the width dimension of the air filter 12 in the vertical direction. Even if there is an individual difference in the width dimension in the direction, it is possible to hold the air filter 12 while suppressing generation of a gap between the second movable guide rail 114 and the air filter holding guide rail 13. Accordingly, it is possible to prevent the air from leaking from between the second movable guide rail 114 and the air filter holding guide rail 13 and dust and insects from entering the room. Thus, by fixing the air filter 12 while pressing it toward the top surface 51, it is possible to reduce the gap in the holding structure of the air filter 12, and the air filter 12 is partitioned by the air filter 12 in the supply air passage 5A. The flow of air other than the air filter 12 from the space upstream of the air filter 12 to the space downstream of the air filter 12 can be suppressed.
　また、エアフィルター１２は、メンテナンスカバー９を閉じることにより、メンテナンスカバー９と後面５４とに挟まれた状態で固定される。これにより、エアフィルター１２の保持構造における隙間を減らすことが可能であり、給気通風路５Ａにおいてエアフィルター１２によって区画されるエアフィルター１２よりも上流側の空間からエアフィルター１２よりも下流側の空間へのエアフィルター１２以外での空気の流れを、より抑制することができる。そして、エアフィルター１２は、メンテナンスカバー９と後面５４とに密着した状態で固定されることが好ましい。 {Circle around (2)} By closing the maintenance cover 9, the air filter 12 is fixed while being sandwiched between the maintenance cover 9 and the rear surface 54. Thereby, it is possible to reduce the gap in the holding structure of the air filter 12, and from the space upstream of the air filter 12 defined by the air filter 12 in the supply air passage 5 </ b> A to the downstream of the air filter 12. The flow of air other than the air filter 12 into the space can be further suppressed. It is preferable that the air filter 12 is fixed in a state in which the air filter 12 is in close contact with the maintenance cover 9 and the rear surface 54.
　また、エアフィルター保持ガイドレール１３とエアフィルター１２との間にシール部材１８を設けることにより、シール部材１８がエアフィルター１２に押し当てられ、シール部材１８が圧縮される。これにより、第２可動ガイドレール１１４とエアフィルター保持ガイドレール１３との間の隙間の発生をより抑制することができる。 Also, by providing the seal member 18 between the air filter holding guide rail 13 and the air filter 12, the seal member 18 is pressed against the air filter 12 and the seal member 18 is compressed. Thereby, the generation of a gap between the second movable guide rail 114 and the air filter holding guide rail 13 can be further suppressed.
　また、熱交換器８は、外装箱５内において、図６に円形矢印で示す熱交換器８の軸を中心とした一方向側への回転、および熱交換器８の軸を中心とした円形矢印と逆方向である他方向側への回転が可能とされている。このため、熱交換器８を、外装箱５への取り付け後の適正な姿勢から熱交換器８の軸を中心とした他方向側へわずかに回転させた状態で外装箱５内へスライドさせて挿入することができる。 Further, the heat exchanger 8 is rotated in one direction around the axis of the heat exchanger 8 indicated by a circular arrow in FIG. Rotation in the other direction, which is opposite to the direction of the arrow, is enabled. For this reason, the heat exchanger 8 is slid into the outer box 5 while being slightly rotated in the other direction around the axis of the heat exchanger 8 from an appropriate posture after being attached to the outer box 5. Can be inserted.
　この場合には、第１固定ガイドレール１１１に貼り付けられたシール部材１８および第１固定ガイドレール１１１と第１熱交換器枠２２１との間を離し、第２固定ガイドレール１１２に貼り付けられたシール部材１８および第２固定ガイドレール１１２と第２熱交換器枠２２２との間を離し、第１可動ガイドレール１１３に貼り付けられたシール部材１８および第１可動ガイドレール１１３と第３熱交換器枠２２３との間を離し、第２可動ガイドレール１１４に貼り付けられたシール部材１８および第２可動ガイドレール１１４と第４熱交換器枠２２４との間を離した状態で、熱交換器８を外装箱５内へスライドさせて挿入することができる。これにより、メンテナンス開口１７から外装箱５内への熱交換器８の挿入がより容易になる。 In this case, the seal member 18 attached to the first fixed guide rail 111 and the space between the first fixed guide rail 111 and the first heat exchanger frame 221 are separated and attached to the second fixed guide rail 112. The seal member 18 and the first movable guide rail 113 attached to the first movable guide rail 113 are separated from the seal member 18 and the second fixed guide rail 112 and the second heat exchanger frame 222, and the third heat The heat exchanger is separated from the exchanger frame 223, and the heat exchange is performed in a state where the seal member 18 attached to the second movable guide rail 114 and the second movable guide rail 114 are separated from the fourth heat exchanger frame 224. The container 8 can be slid and inserted into the outer box 5. This makes it easier to insert the heat exchanger 8 from the maintenance opening 17 into the exterior box 5.
　一方、メンテナンス時には、上述した熱交換器８およびエアフィルター１２の外装箱５への取り付け時と反対の作業を行えばよい。すなわち、第１可動ガイドレール１１３を上方側すなわち天面５１側に移動させた位置に固定し、第１可動ガイドレール１１３に貼り付けられたシール部材１８を第３熱交換器枠２２３の内側面から離す。この結果、第１可動ガイドレール１１３による回転力Ｆが解除され、第１可動ガイドレール１１３がシール部材１８を介して第３熱交換器枠２２３を下方に押圧する状態が解除される。 On the other hand, at the time of maintenance, the opposite operation to the above-described operation of attaching the heat exchanger 8 and the air filter 12 to the outer case 5 may be performed. That is, the first movable guide rail 113 is fixed at a position moved upward, that is, toward the top surface 51, and the seal member 18 attached to the first movable guide rail 113 is fixed to the inner surface of the third heat exchanger frame 223. Away from As a result, the rotational force F by the first movable guide rail 113 is released, and the state in which the first movable guide rail 113 presses the third heat exchanger frame 223 downward via the seal member 18 is released.
　さらに、第２可動ガイドレール１１４を下方側すなわち底面５２側に移動させた位置に固定し、第２可動ガイドレール１１４に貼り付けられたシール部材１８を第４熱交換器枠２２４の内側面から離す。この結果、第２可動ガイドレール１１４による回転力Ｆが解除され、第２可動ガイドレール１１４がシール部材１８を介して第４熱交換器枠２２４を上方に押圧する状態が解除される。この結果、熱交換器８を容易にスライドさせて外装箱５から抜き取ることが可能となり、熱交換器８および外装箱５の内部のメンテナンスを行うことができる。 Further, the second movable guide rail 114 is fixed at a position moved downward, that is, toward the bottom surface 52, and the seal member 18 attached to the second movable guide rail 114 is removed from the inner surface of the fourth heat exchanger frame 224. Let go. As a result, the rotational force F by the second movable guide rail 114 is released, and the state in which the second movable guide rail 114 presses the fourth heat exchanger frame 224 upward via the seal member 18 is released. As a result, the heat exchanger 8 can be easily slid and extracted from the outer box 5, so that the inside of the heat exchanger 8 and the outer box 5 can be maintained.
　また、第１可動ガイドレール１１３を上方側すなわち天面５１側に移動させた位置に固定することで、エアフィルター１２の下面が第２可動ガイドレール１１４から離れ、またはエアフィルター保持ガイドレール１３に貼り付けられたシール部材１８からエアフィルター１２の上面が離れる。この結果、エアフィルター保持ガイドレール１３に貼り付けられたシール部材１８と第２可動ガイドレール１１４との間にエアフィルター１２の縦方向の幅寸法よりも大きい寸法のクリアランスが設けられる。また、エアフィルター保持ガイドレール１３にシール部材１８が貼り付けられていない場合には、エアフィルター保持ガイドレール１３の内底面と第２可動ガイドレール１１４との間に、エアフィルター１２の縦方向の幅寸法よりも大きい寸法のクリアランスが設けられることになる。 In addition, by fixing the first movable guide rail 113 to the upper side, that is, the position moved to the top surface 51 side, the lower surface of the air filter 12 is separated from the second movable guide rail 114 or the air filter holding guide rail 13 The upper surface of the air filter 12 is separated from the attached seal member 18. As a result, a clearance having a size larger than the vertical width of the air filter 12 is provided between the seal member 18 attached to the air filter holding guide rail 13 and the second movable guide rail 114. When the seal member 18 is not attached to the air filter holding guide rail 13, the vertical length of the air filter 12 is set between the inner bottom surface of the air filter holding guide rail 13 and the second movable guide rail 114. A clearance having a dimension larger than the width dimension will be provided.
　これにより、エアフィルター１２がエアフィルター保持ガイドレール１３と第２可動ガイドレール１１４とに挟持された状態が解除される。この結果、エアフィルター１２を容易にスライドさせて外装箱５から抜き取ることが可能となり、エアフィルター１２および外装箱５の内部のメンテナンスを行うことができる。また、エアフィルター保持ガイドレール１３に貼り付けられたシール部材１８をエアフィルター１２との干渉によって劣化させることなく、干渉によるシール部材１８の破れおよび剥がれを防止して、エアフィルター１２を着脱することが可能である。また、エアフィルター１２の着脱時におけるエアフィルター１２の押し込み荷重および引き出し荷重を小さくすることができる。 Thereby, the state in which the air filter 12 is sandwiched between the air filter holding guide rail 13 and the second movable guide rail 114 is released. As a result, the air filter 12 can be easily slid and removed from the outer box 5, and the inside of the air filter 12 and the outer box 5 can be maintained. Further, the seal member 18 attached to the air filter holding guide rail 13 is not degraded by the interference with the air filter 12, and the tear and peeling of the seal member 18 due to the interference is prevented, and the air filter 12 is attached and detached.

It is held between the air filter holding guide rail 13. The second movable guide rail 114 is separated from the heat exchanger 8 and the air filter 12 at a predetermined lower second position in the moving direction.
　また、第１可動ガイドレール１１３は、移動方向において予め定められた下方側の第３の位置において、熱交換器８の適正な取り付け位置において熱交換器８を支持および固定する。また、第１可動ガイドレール１１３は、熱交換器８が支持および固定されない、移動方向において予め定められた第４の位置において、エアフィルター１２から離間している。 The first movable guide rail 113 supports and fixes the heat exchanger 8 at an appropriate mounting position of the heat exchanger 8 at a predetermined lower third position in the moving direction. Further, the first movable guide rail 113 is separated from the air filter 12 at a predetermined fourth position in the moving direction where the heat exchanger 8 is not supported and fixed.

The flow of air other than the air filter 12 from the space upstream of the filter 12 to the space downstream of the air filter 12 can be suppressed. Accordingly, it is possible to prevent the air from leaking from between the second movable guide rail 114 and the air filter holding guide rail 13 and to prevent impurities such as dust and insects from entering the room, resulting in the holding structure of the air filter 12. Therefore, it is possible to suppress impurities from entering the room. Thereby, the heat exchange type ventilation device 100 can increase the cleanliness of the air introduced into the room.
　また、熱交換型換気装置１００は、熱交換器８を固定することによりエアフィルター１２が同時に固定され、熱交換器８の固定を解除することによりエアフィルター１２の固定が同時に解除されるため、エアフィルター１２の着脱が容易である。 Further, in the heat exchange type ventilation device 100, since the air filter 12 is simultaneously fixed by fixing the heat exchanger 8, and the fixing of the air filter 12 is simultaneously released by releasing the fixing of the heat exchanger 8, The attachment and detachment of the air filter 12 is easy.
　また、熱交換型換気装置１００は、エアフィルター保持ガイドレール１３、シール部材１８、および熱交換器８を固定するガイドレール１１といった簡単な構成によりエアフィルター１２を固定可能であり、耐久性にも問題が生じない。 In addition, the heat exchange type ventilator 100 can fix the air filter 12 with a simple configuration such as the guide rail 11 for fixing the air filter holding guide rail 13, the seal member 18, and the heat exchanger 8, and the durability is also improved. No problem.
　すなわち、熱交換型換気装置１００は、簡単な構成で、エアフィルター１２の着脱を伴う場合のメンテナンス性と、塵埃および虫などの不純物の室内への侵入の抑制とを実現できる。 That is, the heat exchange type ventilation device 100 can realize, with a simple configuration, maintainability when the air filter 12 is attached and detached and suppression of impurities such as dust and insects from entering the room.
