Further, as shown in FIG. 4, a substantially intermediate portion of the first belt 41 is fixed to a belt fixing portion 37 </ b> E formed at the upper end portion of the third-stage lifting frame 37.

また、2段目の昇降枠36の下端部36Eには、図7に示すように、上記第1ベルト41よりも内側に配置される第2ベルト42の一端が固定されている。この第2ベルト42は、図6に示すように、3段目の昇降枠37の上端に形成された上部ローラ58に巻かれて、この3段目の昇降枠37の前面を下方に延びる。そして、この第2ベルト42の他端は、図7に示すように、3段目の昇降枠37の下端に形成された下部ローラ59に巻かれて、当該3段目の昇降枠37の背面を上方に延び、上記2段目の昇降枠36の下端部36Eに連結されている。さらに、第2ベルト42の略中間部は、図4に示すように、4段目の昇降枠38の上端部に形成されたベルト固定部38Hに固定されている。
フィルタ昇降モータ39が正回転された場合、ラック55とピニオン53との噛み合いによって、2段目の昇降枠36が下降する。ここで、2段目の昇降枠36に巻かれた第1ベルト41の略中間部は3段目の昇降枠37の上端部に形成されたベルト固定部37Eに固定されているため、2段目の昇降枠36の下降に伴い3段目の昇降枠37も下降する。さらに、3段目の昇降枠37に巻かれた第2ベルト42の略中間部は4段目の昇降枠38の上端に形成されたベルト固定部38Hに固定されているため、3段目の昇降枠37の下降に伴い4段目の昇降枠38も下降する。
これにより、フィルタ昇降モータ39が正回転駆動されると、図3に示すように、昇降枠35〜38がすべて引き出されて、フィルタ33が降下する。本構成では、フィルタ昇降装置31は、少なくともフィルタ33の長さ以上、本体3の外部に昇降枠35〜38を引き出し可能となっている。言い換えれば、フィルタ昇降装置31は、フィルタ33の略全面が本体3の外部に露出する長さHだけ、本体3の外部に昇降枠35〜38を引き出せるようになっている。この構成によれば、フィルタ33の着脱時に、このフィルタ33の略全面が外部に露出するため、フィルタ33の着脱作業を非常に容易に行うことができる。さらに、従来のものに比べて、4段目、すなわち最下段の昇降枠38がより低い位置まで下降するため、背の低いユーザであっても簡単にフィルタ33の着脱を行うことができる。
一方、フィルタ昇降モータ39が逆回転された場合、ラック55とピニオン53との噛み合いによって、2段目の昇降枠36が上方に引き上げられるとともに、上記第1ベルト41及び第2ベルト42によって、3段目の昇降枠37及び4段目の昇降枠38が上方に引き上げられる。これにより、フィルタ昇降モータ39が逆回転駆動されると、図2に示すように、昇降枠35〜38がすべて引き込まれて、フィルタ33が格納される。
Further, as shown in FIG. 7, one end of the second belt 42 disposed on the inner side of the first belt 41 is fixed to the lower end portion 36 </ b> E of the second-stage lifting frame 36. As shown in FIG. 6, the second belt 42 is wound around an upper roller 58 formed at the upper end of the third-stage lifting frame 37 and extends downward on the front surface of the third-stage lifting frame 37. The other end of the second belt 42 is wound around a lower roller 59 formed at the lower end of the third-stage lifting frame 37 as shown in FIG. And is connected to the lower end 36E of the second-stage lifting frame 36. Further, as shown in FIG. 4, the substantially middle portion of the second belt 42 is fixed to a belt fixing portion 38 </ b> H formed at the upper end portion of the fourth-stage lifting frame 38.
When the filter elevating motor 39 is rotated forward, the second elevating frame 36 is lowered by the meshing of the rack 55 and the pinion 53. Here, since the substantially middle portion of the first belt 41 wound around the second-stage lifting frame 36 is fixed to a belt fixing portion 37E formed at the upper end of the third-stage lifting frame 37, the second stage As the eye lifting frame 36 is lowered, the third stage lifting frame 37 is also lowered. Further, since the substantially middle portion of the second belt 42 wound around the third-stage lifting frame 37 is fixed to a belt fixing portion 38H formed at the upper end of the fourth-stage lifting frame 38, the third-stage lifting frame 37 As the elevating frame 37 is lowered, the fourth elevating frame 38 is also lowered.
As a result, when the filter lifting / lowering motor 39 is driven to rotate in the forward direction, as shown in FIG. 3, all the lifting frames 35 to 38 are pulled out, and the filter 33 is lowered. In this configuration, the filter elevating device 31 can draw the elevating frames 35 to 38 to the outside of the main body 3 at least as long as the length of the filter 33. In other words, the filter lifting and lowering device 31 can draw the lifting frames 35 to 38 to the outside of the main body 3 by a length H that the substantially entire surface of the filter 33 is exposed to the outside of the main body 3. According to this configuration, when the filter 33 is attached / detached, substantially the entire surface of the filter 33 is exposed to the outside, so that the attachment / detachment work of the filter 33 can be performed very easily. Furthermore, since the fourth stage, that is, the lowermost elevating frame 38 is lowered to a lower position as compared with the conventional one, even a short user can easily attach and detach the filter 33.
On the other hand, when the filter elevating motor 39 is rotated in the reverse direction, the second elevating frame 36 is pulled upward by the meshing of the rack 55 and the pinion 53, and the first belt 41 and the second belt 42 3 The stage lifting frame 37 and the fourth stage lifting frame 38 are pulled upward. Thus, when the filter lifting / lowering motor 39 is driven to rotate in the reverse direction, as shown in FIG. 2, all the lifting frames 35 to 38 are pulled in and the filter 33 is stored.

本構成では、フィルタ昇降装置31は、上述のように、フィルタ33の略全面を本体3の外部に露出するために、1〜4段に区別された昇降枠35〜38を備えて構成されている。ここで、フィルタ33の略全面を本体3の外部に露出する目的であれば、4段に限らず、例えば、3段や5段の構造とすることも考えられる。しかしながら、フィルタ昇降装置を3段の昇降枠で構成した場合、各段の昇降枠の高さが大きくなるため、これら昇降枠を収容する空気調和装置本体が高さ方向に大きくなってしまう。
一方、フィルタ昇降装置を5段の昇降枠で構成した場合、各昇降枠を上昇・下降するための機構が複雑になるとともに、各昇降枠が5段に積層されるため、空気調和装置本体が厚み方向に大きくなってしまう。
これに対して、本構成では、フィルタ昇降装置31を4段の昇降枠35〜38で構成したため、従来のものに比べて空気調和装置本体3を高さ方向及び厚み方向に大型化することなく当該本体3内にフィルタ昇降装置31を配置することができる。
In this configuration, as described above, the filter lifting / lowering device 31 includes the lifting frames 35 to 38 that are distinguished in one to four stages in order to expose the substantially entire surface of the filter 33 to the outside of the main body 3. Yes. Here, for the purpose of exposing substantially the entire surface of the filter 33 to the outside of the main body 3, not only four stages but also a three-stage or five-stage structure may be considered. However, when the filter lifting / lowering device is composed of three-stage lifting frames, the height of the lifting frames at each stage is increased, so that the air conditioner main body that accommodates these lifting frames is increased in the height direction.
On the other hand, when the filter elevating device is composed of five elevating frames, the mechanism for raising and lowering each elevating frame is complicated and each elevating frame is stacked in five stages. It becomes larger in the thickness direction.
On the other hand, in this structure, since the filter raising / lowering device 31 was comprised with the four steps raising / lowering frames 35-38, compared with the conventional thing, the air conditioning apparatus main body 3 is not enlarged in a height direction and a thickness direction. A filter lifting / lowering device 31 can be disposed in the main body 3.

また、昇降枠35〜38がすべて引き出された状態では、図3に示すように、1段目の枠体35Aの上縁が、所定位置まで低く下がって維持されており、枠体35Aの上縁の上方に形成される空間を通じて、電気式除塵フィルタ40が装着される。この電気式除塵フィルタ40は、図2に示すように、熱交換器7とフィルタ33との間に装着され、フィルタ33を通過した室内空気中の塵埃を捕集が可能である。   Further, in the state where all the lifting frames 35 to 38 are pulled out, as shown in FIG. 3, the upper edge of the first-stage frame body 35A is lowered and maintained to a predetermined position. The electric dust filter 40 is mounted through a space formed above the edge. As shown in FIG. 2, the electric dust removing filter 40 is mounted between the heat exchanger 7 and the filter 33, and can collect dust in the indoor air that has passed through the filter 33.

フィルタ33は、上述したように4段目の昇降枠38の下端に固定されるため、昇降枠35〜38が上昇し、フィルタ33が空気調和装置本体3の前面11から天面13に進入する過程では、フィルタ33の上部が湾曲して前面11から天面13に進入する。
この空気調和装置本体3の天面13は、図2に示すように、空気調和装置本体3の上部3Aと、この上部3Aの上に間隔δをあけて着脱自在に取り付けられる天面パネル43とで構成され、上述したフィルタ33の上部は湾曲して該隙間δ内に進入し、昇降枠35〜38がすべて引き込まれた状態(図2)では、フィルタ33が、前面11及び天面13の各吸込口15,17を同時に覆う。
Since the filter 33 is fixed to the lower end of the fourth-stage lifting frame 38 as described above, the lifting frames 35 to 38 are raised, and the filter 33 enters the top surface 13 from the front surface 11 of the air conditioner body 3. In the process, the upper part of the filter 33 is curved and enters the top surface 13 from the front surface 11.
As shown in FIG. 2, the top surface 13 of the air conditioner main body 3 includes an upper part 3A of the air conditioner main body 3 and a top panel 43 that is detachably mounted on the upper part 3A with a gap δ. In the state in which the upper part of the filter 33 described above is curved and enters the gap δ and the lifting frames 35 to 38 are all retracted (FIG. 2), the filter 33 is formed on the front surface 11 and the top surface 13. Each inlet 15 and 17 is covered simultaneously.

本実施の形態では、図3に示すように、天面パネル43の前縁部に対し、各フィルタ33に対応して、フィルタ33の上部の方向転換部、すなわちフィルタ33が前面11から天面13に方向転換する部位に突出して、フィルタ33の上部を前面11から天面13に滑らかに案内可能に、フィルタ案内部43Aが一体に設けられている。また図2に示すように、方向転換した後のフィルタ33の先端部を、天面パネル43の下面に対し滑らかに案内自在に、天面パネル43の前後方向に延びる桁部43Bの下面に、湾曲リブ45が一体に設けられている。この構成では、フィルタ案内部43A、及び湾曲リブ45の協働によって、フィルタ33の上部が、空気調和装置本体3の前面11から天面13に対し、滑らかに案内されて進入が可能となる。   In the present embodiment, as shown in FIG. 3, with respect to the front edge portion of the top panel 43, the direction changing portion at the top of the filter 33 corresponding to each filter 33, that is, the filter 33 is connected to the top surface from the front surface 11. The filter guide 43A is integrally provided so that the upper portion of the filter 33 can be smoothly guided from the front surface 11 to the top surface 13 so as to project to a portion whose direction is changed to 13. Further, as shown in FIG. 2, the tip of the filter 33 after the direction change is smoothly guided to the lower surface of the top panel 43, and on the lower surface of the girder 43 </ b> B extending in the front-rear direction of the top panel 43. The curved rib 45 is provided integrally. In this configuration, the upper portion of the filter 33 is smoothly guided from the front surface 11 to the top surface 13 of the air conditioner main body 3 by the cooperation of the filter guide portion 43A and the curved rib 45, thereby allowing entry.

上記前面パネル5は、図2に示すように、空気調和装置1の不作動状態において、フィルタ昇降装置31を完全に覆うように、空気調和装置本体3の前面11に隙間無く閉じている。そして、空気調和装置1を作動する段階、或いはフィルタ昇降装置31を作動し、昇降枠35〜38を降下する段階には、図8及び図9に示すように、リンク機構46を介して、前面パネル5が前方に押し出され、空気吸い込みのための隙間確保、或いは昇降枠35〜38の降下のための隙間が確保される。   As shown in FIG. 2, the front panel 5 is closed to the front surface 11 of the air conditioner main body 3 without a gap so as to completely cover the filter elevating device 31 when the air conditioner 1 is not in operation. And in the step of operating the air conditioner 1 or the step of operating the filter lifting device 31 and lowering the lifting frames 35 to 38, as shown in FIGS. The panel 5 is pushed forward, and a clearance for air suction or a clearance for lowering the lifting frames 35 to 38 is secured.

また、フィルタ昇降装置31は、上述したように、昇降枠35〜38の吸込口15に対向する面が上を向くように、空気調和装置本体3の前面11に傾斜して取り付けられている。具体的には、図6に示すように、フィルタ昇降装置31は、昇降枠35〜38に支持されるフィルタ33が鉛直方向に対して角度Aで傾斜するように取り付けられている。
この角度Aは、昇降枠35〜38を下降する際に、フィルタ33の付着面33Aに付着した塵埃が付着面33Aから脱落しない角度に設定され、本実施形態では、角度Aは3°に設定されている。
この角度Aを、3°以上とすることで、より効果的な付着力が得られ、塵埃の付着面33Aからの脱落を防止できる。さらに、空気調和装置1が不作動状態で昇降枠35〜38がすべて引き込まれた状態においても、付着面33Aが傾斜しているため、塵埃の脱落を防止できる。この角度Aは大きければ大きいほど、塵埃の付着面33Aからの脱落を防止できる。
In addition, as described above, the filter lifting / lowering device 31 is attached to the front surface 11 of the air conditioner main body 3 so that the surface of the lifting frames 35 to 38 facing the suction port 15 faces upward. Specifically, as shown in FIG. 6, the filter lifting / lowering device 31 is attached so that the filter 33 supported by the lifting frames 35 to 38 is inclined at an angle A with respect to the vertical direction.
This angle A is set to an angle at which dust attached to the attachment surface 33A of the filter 33 does not fall off from the attachment surface 33A when descending the lifting frames 35 to 38. In this embodiment, the angle A is set to 3 °. Has been.
By setting the angle A to 3 ° or more, a more effective adhesion force can be obtained and dust can be prevented from falling off from the adhesion surface 33A. Furthermore, even when the air-conditioning apparatus 1 is in an inoperative state and the lifting frames 35 to 38 are all retracted, the attachment surface 33A is inclined, so that dust can be prevented from falling off. The larger this angle A is, the more the dust can be prevented from falling off from the attachment surface 33A.

本実施形態によれば、空気調和装置本体3が熱交換器7及び送風機9を備え、熱交換器7に対向させて前面及び天面に吸込口15,17を備え、該吸込口15,17に亘ってフィルタ33を配置し、該フィルタ33を上昇・下降させるフィルタ昇降装置31を備え、このフィルタ昇降装置31は、フィルタ33を保持する1〜4段に区別された昇降枠35〜38を備え、これら昇降枠35〜38を、少なくとも前面から天面に亘るフィルタ33の長さ以上である長さHだけ空気調和装置本体3の外部に引き出し可能に構成したため、フィルタ33の着脱時に、このフィルタ33の略全面が外部に露出するため、フィルタ33の着脱作業を非常に容易に行うことができる。   According to this embodiment, the air conditioning apparatus body 3 includes the heat exchanger 7 and the blower 9, and includes the suction ports 15 and 17 on the front surface and the top surface so as to face the heat exchanger 7, and the suction ports 15 and 17.
