Description

フィルタ清掃装置Filter cleaning device
　本発明は、空気調和機などに備えられ、フィルタ上に付着した埃を除去するフィルタ清掃装置に関する。 The present invention relates to a filter cleaning device that is provided in an air conditioner or the like and removes dust adhering to a filter.
　空気調和機には、室内機の空気吸入口に、吸い込む空気に含まれている埃を除去するためのフィルタが備えられている。従来の空気調和機においては、フィルタに付着した埃の清掃は、手動によって行われていた。すなわち、人手によりフィルタを室内機から外して、手動でフィルタを清掃する必要があった。 The air conditioner is equipped with a filter for removing dust contained in the air to be sucked into the air intake port of the indoor unit. In the conventional air conditioner, the dust adhering to the filter is manually cleaned. That is, it is necessary to manually remove the filter from the indoor unit and manually clean the filter.
　しかし、室内機の設置箇所によってはフィルタを外す作業が困難であり、特に室内機が高所に設置されている場合には、フィルタの清掃は非常に手間のかかる作業である。そのため、昨今の空気調和機には、フィルタを外すことなく、装置内で自動的にフィルタを清掃する機能を備えているものもある。 However, it is difficult to remove the filter depending on the installation location of the indoor unit, and particularly when the indoor unit is installed at a high place, cleaning the filter is very laborious. Therefore, some recent air conditioners have a function of automatically cleaning the filter in the apparatus without removing the filter.
　例えば、特許文献１には、フィルタに付着した塵埃を自動的に除去するフィルタ清掃機構付きの空調室内機が開示されている。特許文献１に記載の空調室内機（２）は、フィルタ（２１）を搬送させながら前記フィルタ（２１）に付着した塵埃を除去する。この空調室内機（２）は、前記フィルタ（２１）の網目に入り込む複数の細線部材（４１１ａ）を有し、回転時に前記網目と前記細線部材（４１１ａ）との噛み合いによって前記フィルタ（２１）を搬送するローラー（４１）と、前記フィルタ（２１）を挟んで前記ローラー（４１）と対峙する位置に配備されるブラシ（６１）と、を備え、前記細線部材（４１１ａ）は、前記ローラー（４１）から径に対して所定方向に傾いて突出しており、前記ブラシ（６１）は、前記細線部材（４１１ａ）を起こす方向と逆の方向に回転する。 For example, Patent Document 1 discloses an air conditioning indoor unit with a filter cleaning mechanism that automatically removes dust adhering to a filter. The air conditioning indoor unit (2) described in Patent Document 1 removes dust attached to the filter (21) while transporting the filter (21). This air conditioning indoor unit (2) has a plurality of fine wire members (411a) that enter the mesh of the filter (21), and the filter (21) is brought into engagement with the mesh and the fine wire member (411a) during rotation. A roller (41) for conveying, and a brush (61) disposed at a position facing the roller (41) across the filter (21). The thin wire member (411a) includes the roller (41 ) Protrudes in a predetermined direction with respect to the diameter, and the brush (61) rotates in a direction opposite to the direction in which the thin wire member (411a) is raised.

　上述の特許文献１のように、フィルタの自動清掃機能を備えている空気調和機には、フィルタを間に挟んでブラシと対向する位置に、フィルタを押さえるための回転部材（例えば、特許文献１のローラー４１）が設けられている。この回転部材は、軸方向に長い円筒状に形成され、室内側熱交換器の前方に配置される。また、この回転部材には、円筒形状の長手方向の少なくとも一方の端部に、フィルタを搬送させるためのギア（例えば、特許文献１のローラーギア３２）が設けられている。 As in the above-described Patent Document 1, an air conditioner having a filter automatic cleaning function includes a rotating member for holding the filter at a position facing the brush with the filter interposed therebetween (for example, Patent Document 1). The roller 41) is provided. The rotating member is formed in a cylindrical shape that is long in the axial direction, and is disposed in front of the indoor heat exchanger. Further, the rotating member is provided with a gear (for example, a roller gear 32 of Patent Document 1) for transporting the filter at at least one end in the longitudinal direction of the cylindrical shape.
　そして、フィルタを間に挟んでブラシと対向する位置に配置された回転部材は、一般的に、フィルタを搬送させるためのギアと同軸上で回転する。そのため、回転部材の径は、ブラシの方へフィルタを押し出すために、ギアと略同一径となっている。 Rotating members arranged at positions facing the brush with the filter interposed therebetween generally rotate coaxially with a gear for transporting the filter. Therefore, the diameter of the rotating member is substantially the same as that of the gear in order to push the filter toward the brush.
　しかしながら、このような回転部材を設けることによって、室内側熱交換器への空気通路が塞がれることになる。すなわち、フィルタ清掃装置（特に、回転部材）が空気吸入口から室内側熱交換器に至る空気通路を狭めてしまうことになる。空気通路が狭くなることにより、空気調和機の性能低下につながる可能性が高くなる。 However, by providing such a rotating member, the air passage to the indoor heat exchanger is blocked. That is, the filter cleaning device (particularly the rotating member) narrows the air passage from the air inlet to the indoor heat exchanger. Narrowing the air passage increases the possibility of reducing the performance of the air conditioner.
　そこで、本発明では、空気通路が狭くなることを低減したフィルタ清掃装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a filter cleaning device that reduces the narrowing of the air passage.
　本発明の一局面にかかるフィルタ清掃装置は、フィルタに付着した埃を清掃するフィルタ清掃装置であって、フィルタの表面上の塵埃を除去する埃取り部材と、前記埃取り部材に沿うように前記フィルタを移動させるフィルタ駆動部と、前記フィルタを間に挟んで前記埃取り部材と対向する位置に配置され、前記フィルタの移動に連動して回転する回転部材とを備えている。 A filter cleaning device according to one aspect of the present invention is a filter cleaning device that cleans dust adhering to a filter, the dust removing member removing dust on the surface of the filter, and the dust removing member along the dust removing member. A filter driving unit that moves the filter; and a rotating member that is disposed at a position facing the dust removing member with the filter interposed therebetween and rotates in conjunction with the movement of the filter.
　上記の本発明の一局面にかかるフィルタ清掃装置において、前記フィルタには、前記フィルタの移動方向に沿って複数の突起部が形成され、前記フィルタ駆動部は、前記突起部と噛み合う回転ギアを有しており、前記回転部材の径は、前記回転ギアの径よりも小さくなっていてもよい。 In the filter cleaning device according to one aspect of the present invention described above, the filter has a plurality of protrusions along the moving direction of the filter, and the filter driving unit has a rotating gear that meshes with the protrusions. The diameter of the rotating member may be smaller than the diameter of the rotating gear.
　上記の本発明の一局面にかかるフィルタ清掃装置では、側面視において、前記回転ギアの内側に前記回転部材が位置していてもよい。 In the filter cleaning device according to one aspect of the present invention, the rotating member may be located inside the rotating gear in a side view.
　上記の本発明の一局面にかかるフィルタ清掃装置において、前記フィルタには、前記フィルタの移動方向に沿って複数の突起部が形成されており、前記回転部材は、前記突起部と噛み合うギアを有していてもよい。なお、前記回転部材のギアと噛み合う前記突起部は、前記フィルタ駆動部の回転ギアと噛み合う前記突起部と、同一の部材であってもよいし、別の部材であってもよい。 In the filter cleaning device according to one aspect of the present invention described above, the filter has a plurality of protrusions along the moving direction of the filter, and the rotating member has a gear that meshes with the protrusion. You may do it. The protrusion that meshes with the gear of the rotating member may be the same member as the protrusion that meshes with the rotating gear of the filter driving unit, or may be a different member.
　上記の本発明の一局面にかかるフィルタ清掃装置において、前記回転部材の表面には、ブラシが設けられていてもよい。 In the filter cleaning device according to one aspect of the present invention, a brush may be provided on the surface of the rotating member.
　上記の本発明の一局面にかかるフィルタ清掃装置では、前記回転部材の表面に設けられたブラシと前記フィルタの裏面とが接触することによって、前記回転部材は回転してもよい。 In the filter cleaning device according to one aspect of the present invention described above, the rotating member may rotate when the brush provided on the surface of the rotating member comes into contact with the back surface of the filter.

As shown in FIG. 1, the indoor unit 1 has a substantially rectangular parallelepiped shape, and is usually used by being hung on the upper part of the wall of the room. As described above, the indoor unit 1 is provided with the indoor heat exchanger 31. The indoor heat exchanger 31 is connected to a compressor on the outdoor unit side through a refrigerant pipe (not shown). Thereby, this indoor unit 1 and the outdoor unit constitute a refrigeration cycle, and as a result, function as an air conditioner. A control unit that controls the refrigeration cycle is provided in the electrical component unit in the indoor unit 1.
　図３に示すように、室内機１は、主として、筐体１０、フィルタ清掃装置２０、フィルタ２１、空気調和ユニット３０、および電装品ユニット（図示せず）などを備えている。以下、これらの各構成部材についてそれぞれ詳述する。 As shown in FIG. 3, the indoor unit 1 mainly includes a housing 10, a filter cleaning device 20, a filter 21, an air conditioning unit 30, an electrical component unit (not shown), and the like.

　なお、説明の便宜上、前面パネル１１が配置されている側を室内機１の前面側とし、背面パネル１３が配置されている側を室内機１の背面側とする。そして、室内機１の前面側から背面側、または背面側から前面側へ向かう方向のことを、前後方向という。また、室内機１の通常の設置状態において、上方から下方または下方から上方へ向かう方向のことを、上下方向または鉛直方向という。また、この上下方向に交差または直交する方向のことを、水平方向または左右方向という。 For convenience of explanation, the side on which the front panel 11 is arranged is the front side of the indoor unit 1, and the side on which the back panel 13 is arranged is the back side of the indoor unit 1. The direction from the front side to the back side of the indoor unit 1 or from the back side to the front side is referred to as the front-rear direction. Moreover, in the normal installation state of the indoor unit 1, the direction from the top to the bottom or from the bottom to the top is referred to as the up-down direction or the vertical direction. A direction intersecting or orthogonal to the vertical direction is referred to as a horizontal direction or a horizontal direction.
　筐体１０の上面には、吸込み口１４が設けられている。この吸込み口１４から、室内機１が設置されている室内の空気が室内機１内に取り込まれる。そして、図３に示すように、この吸込み口１４の真下には、フィルタ２１が配置されている。 A suction port 14 is provided on the upper surface of the housing 10. The indoor air in which the indoor unit 1 is installed is taken into the indoor unit 1 from the suction port 14. As shown in FIG. 3, a filter 21 is disposed directly below the suction port 14.
　前面パネル１１は、筐体１０の前面（正面）に位置する。前面パネル１１は、本体パネル１２に対して開閉可能に取り付けられている。図２には、前面パネル１１が開いている状態を示す。図２に示すように、前面パネル１１の裏面側には、フィルタ清掃装置２０のダストボックス２２Ｒ・２２Ｌが配置されている。 The front panel 11 is located on the front surface (front surface) of the housing 10.

　室内側熱交換器３１は、複数の熱交換器を、クロスフローファン３２を覆う屋根（逆Ｖ字状）のように組み合わせたものである。なお、各熱交換器は、左右両端で複数回折り返された伝熱管（図示せず）に多数の放熱フィン（図示せず）が取り付けられたものであって、冷房運転時には蒸発器として機能し、暖房運転時には凝縮器として機能する。 The indoor heat exchanger 31 is a combination of a plurality of heat exchangers such as a roof (inverted V shape) covering the cross flow fan 32. Each heat exchanger has a large number of radiating fins (not shown) attached to a heat transfer tube (not shown) bent back and forth at both left and right ends, and functions as an evaporator during cooling operation. It functions as a condenser during heating operation.
　クロスフローファン３２は、駆動モータ（図示せず）に連結されている。そして、クロスフローファン３２は、空気調和機の運転中、その駆動モータによって回転駆動され、室内の空気を筐体１０に吸い込んで室内側熱交換器３１に供給すると共に、室内側熱交換器３１で熱交換された空気を室内に送出する。なお、駆動モータは、信号線を介して電装品ユニットに通信接続されており、電装品ユニット内の制御部から送信される制御信号に従って動作する。 The crossflow fan 32 is connected to a drive motor (not shown). The cross flow fan 32 is rotationally driven by the drive motor during the operation of the air conditioner, sucks indoor air into the housing 10 and supplies the indoor air to the indoor heat exchanger 31, and also the indoor heat exchanger 31. The air that has been heat-exchanged in is sent out indoors. The drive motor is communicatively connected to the electrical component unit via a signal line, and operates according to a control signal transmitted from a control unit in the electrical component unit.
　電装品ユニットは、例えば、筐体１０内の右側端部に配置される。電装品ユニットは、中央処理演算部（制御部）、信号送受信部などで構成されている。電装品ユニットは、信号線を介して、冷凍サイクルの各構成部材と接続されている。そして、電装ユニット内の制御部は、使用者の指示、および室温や外気温を検出する温度センサ等の各種センサの検出信号に基づいて、冷凍サイクルを制御し、冷房運転および暖房運転を行う。 The electrical component unit is disposed, for example, at the right end in the housing 10. The electrical component unit includes a central processing calculation unit (control unit), a signal transmission / reception unit, and the like. The electrical component unit is connected to each component of the refrigeration cycle via a signal line. And the control part in an electrical equipment unit controls a refrigerating cycle based on a user's instruction | indication and the detection signal of various sensors, such as a temperature sensor which detects room temperature and external temperature, and performs air_conditionaing | cooling operation and heating operation.
　また、電装品ユニットは、信号線を介して、クロスフローファン３２の駆動モータ、フラップ１５の駆動モータ、フィルタ清掃装置２０の駆動モータ、フィルタ清掃装置２０内の各部材の電源部などとも接続されている。 The electrical component unit is also connected to the drive motor of the cross flow fan 32, the drive motor of the flap 15, the drive motor of the filter cleaning device 20, the power supply unit of each member in the filter cleaning device 20 and the like via signal lines. ing.
　フィルタ２１は、吸込み口１４と室内側熱交換器３１との間に設けられている。説明の便宜上、吸込み口１４と対向しているフィルタ２１の面を表面とし、室内側熱交換器３１と対向しているフィルタ２１の面をフィルタの裏面とする。図３に示すように、フィルタ２１は、筐体１０に設けられた吸込み口１４の形状に沿うように配置されている。フィルタ２１は、吸込み口１４から室内機１の内部に取り込まれる空気に含まれる埃や塵を捕捉する。これにより、室内機１の内部に取り込まれる空気中の埃や塵の量を減らすことができる。 The filter 21 is provided between the suction port 14 and the indoor heat exchanger 31. For convenience of explanation, the surface of the filter 21 facing the suction port 14 is defined as the front surface, and the surface of the filter 21 facing the indoor heat exchanger 31 is defined as the back surface of the filter. As shown in FIG. 3, the filter 21 is disposed along the shape of the suction port 14 provided in the housing 10. The filter 21 captures dust and dirt contained in the air taken into the indoor unit 1 from the suction port 14. Thereby, the amount of dust and dust in the air taken into the indoor unit 1 can be reduced.
　本実施形態にかかる室内機１には、２つのフィルタ２１が、左右に並んで配置されている（図４参照）。右側および左側のフィルタをそれぞれ区別して説明する場合には、左側フィルタを２１Ｌとし、右側フィルタを２１Ｒとする。なお、本発明の一態様の空気調和機におけるフィルタの個数及び配置は、これに限定はされない。例えば、吸込み口１４の全領域をカバーするような１枚のフィルタで構成してもよい。 In the indoor unit 1 according to the present embodiment, two filters 21 are arranged side by side (see FIG. 4). When the right and left filters are described separately, the left filter is 21L and the right filter is 21R. Note that the number and arrangement of the filters in the air conditioner of one embodiment of the present invention are not limited thereto. For example, you may comprise with one filter which covers the whole area | region of the suction inlet 14. FIG.
　フィルタ清掃装置２０は、フィルタ２１上に付着した埃や塵などを除去する装置である。フィルタ清掃装置２０には、矩形の板状を有するフィルタ２１が、フィルタ清掃装置２０の形状に沿うように取り付けられている。フィルタ清掃装置２０には、フィルタ２１上に付着した埃、塵、ゴミなどを収容するダストボックス２２が備えられている。ダストボックス２２は、各フィルタ２１に対してそれぞれ設けられている。すなわち、本実施形態の室内機１には、右側のフィルタ２１Ｒと左側のフィルタ２１Ｌのそれぞれに対して、ダストボックス２２が１個ずつ設けられている。なお、左右のダストボックスを区別して称する場合には、右側ダストボックスを２２Ｒとし、左側ダストボックスを２２Ｌと呼ぶ（図２、図４など参照）。 The filter cleaning device 20 is a device that removes dust and dirt adhering to the filter 21. A filter 21 having a rectangular plate shape is attached to the filter cleaning device 20 so as to follow the shape of the filter cleaning device 20.

That is, in the indoor unit 1 of the present embodiment, one dust box 22 is provided for each of the right filter 21R and the left filter 21L. When the left and right dust boxes are referred to separately, the right dust box is referred to as 22R, and the left dust box is referred to as 22L (see FIGS. 2 and 4).
　＜フィルタ清掃装置について＞
　続いて、室内機１に備えられているフィルタ２１およびフィルタ清掃装置２０のより具体的な構成について、図４から図１１を参照しながら説明する。 <About the filter cleaning device>
Next, more specific configurations of the filter 21 and the filter cleaning device 20 provided in the indoor unit 1 will be described with reference to FIGS. 4 to 11.

FIG. 5 shows a state in which the right dust box 22 </ b> R is removed from the main body portion of the filter cleaning device 20. In FIG. 6, the filter support body 25 of the filter cleaning apparatus 20 is shown. FIG. 7 shows a more specific configuration of the front brush 23, the filter drive gear 24, the back roller 41, and the like that constitute the filter cleaning device 20. FIG. 8 shows a more specific configuration of the filter drive gear 24 and the back roller 41. FIG. 9A shows how dust on the filter 21 is scraped off by the front brush 23. FIG. 9B shows a filter driving gear (filter driving unit) 24 and a rotating gear 41a of the back roller 41 (rotating member).
　フィルタ清掃装置２０は、主として、フィルタ２１の前面側に配置されている。空気調和機が空調運転を行っている状態では、図３および図４などに示すように、フィルタ２１は、その前方側の端部部分のみがフィルタ清掃装置２０と重なるような位置関係で配置されている。そして、フィルタ清掃装置２０によってフィルタ２１の清掃が行われる際には、フィルタ２１は駆動モータ２４Ｍによって駆動されて移動し、フィルタ２１の表面全体がフィルタ清掃装置２０の前面ブラシ２３上を通過するように構成されている。 The filter cleaning device 20 is mainly disposed on the front side of the filter 21. In a state where the air conditioner is performing an air conditioning operation, as shown in FIGS. 3 and 4, the filter 21 is disposed in a positional relationship such that only the end portion on the front side overlaps the filter cleaning device 20. ing. When the filter 21 is cleaned by the filter cleaning device 20, the filter 21 is driven and moved by the drive motor 24M so that the entire surface of the filter 21 passes over the front brush 23 of the filter cleaning device 20. It is configured.
　フィルタ２１は、メッシュ部５１と、メッシュ部５１の周囲を取り囲む枠体（枠部）５２とで構成されている。図１０および図１１には、フィルタ２１のより具体的な構成を示す。 The filter 21 includes a mesh part 51 and a frame body (frame part) 52 surrounding the mesh part 51. 10 and 11 show a more specific configuration of the filter 21. FIG.
　図１０および図１１に示すように、枠体５２は、縦方向（移動方向に平行な方向）の枠部分である縦枠５２Ｖと、横方向（移動方向に交差する方向）の枠部分である横枠５２Ｈとからなる。フィルタ２１は、後述するフィルタ支持体２５に着脱可能に支持されている。 As shown in FIGS. 10 and 11, the frame body 52 is a vertical frame 52 </ b> V that is a vertical frame portion (a direction parallel to the moving direction) and a horizontal frame portion (a direction that intersects the moving direction). It consists of a horizontal frame 52H. The filter 21 is detachably supported by a filter support 25 described later.
　メッシュ部５１は、例えば、ポリエチレンテレフタレートで網目状に形成され、枠体５２は、例えば、ポリプロピレン樹脂などの合成樹脂で形成される。またあるいは、メッシュ部５１と枠体５２とは、ポリプロピレン樹脂等の合成樹脂により一体的に成形されてもよい。 The mesh part 51 is formed in a mesh shape with, for example, polyethylene terephthalate, and the frame body 52 is formed with a synthetic resin such as polypropylene resin. Alternatively, the mesh portion 51 and the frame body 52 may be integrally formed of synthetic resin such as polypropylene resin.
　また、枠体５２は、複数のリブ５３を有している。各リブ５３は、枠体５２の内部を縦または横に略等間隔に延びており、これにより、メッシュ部５１の表面は碁盤目状に区画される。この構成により、フィルタ２１の強度が高まる。 The frame body 52 has a plurality of ribs 53. Each rib 53 extends in the frame body 52 vertically or horizontally at substantially equal intervals, whereby the surface of the mesh portion 51 is partitioned in a grid pattern. With this configuration, the strength of the filter 21 is increased.
　リブ５３は、フィルタ２１の裏面側に設けられていることが好ましい。これにより、メッシュ部５１の表面を、略面一とすることができる。フィルタ２１の表面が略面一であることによって、フィルタ２１の表面に付着した埃や塵などを、フィルタ清掃装置２０によってより容易に取り除くことができる。 The rib 53 is preferably provided on the back side of the filter 21. Thereby, the surface of the mesh part 51 can be made substantially flush. Since the surface of the filter 21 is substantially flush, dust or dirt attached to the surface of the filter 21 can be easily removed by the filter cleaning device 20.
　また、本実施形態では、枠体５２の縦枠５２Ｖの裏面側に、複数のラック（突起部）５４が形成されている。このようなラック５４は、フィルタ２１の移動を駆動するフィルタ駆動ギア２４と噛み合う。そして、駆動モータ２４Ｍによってフィルタ駆動ギア２４が回転駆動されると、これに連動して、フィルタ２１がフィルタ支持体２５のガイド２５ａ（図３など参照）に沿って移動する。すなわち、駆動モータ２４Ｍによってフィルタ駆動ギア２４が回転駆動されると、フィルタ２１がフィルタ支持体２５のガイド２５ａに沿って、室内機１内を前後方向に移動するとともに、室内機１内を上下方向に移動する。 In the present embodiment, a plurality of racks (projections) 54 are formed on the back side of the vertical frame 52V of the frame body 52. Such a rack 54 meshes with the filter drive gear 24 that drives the movement of the filter 21. When the filter drive gear 24 is rotationally driven by the drive motor 24M, the filter 21 moves along the guide 25a (see FIG. 3 and the like) of the filter support 25 in conjunction with this. That is, when the filter drive gear 24 is rotationally driven by the drive motor 24M, the filter 21 moves in the front-rear direction in the indoor unit 1 along the guide 25a of the filter support 25, and moves up and down in the indoor unit 1. Move to.
　次に、フィルタ清掃装置２０の構成について説明する。図３に示すように、フィルタ清掃装置２０は、主な構成部材として、ダストボックス２２、前面ブラシ（埃取り部材）２３、フィルタ駆動ギア２４、背面ローラ（回転部材）４１（図５参照）、およびフィルタ支持体２５などを備えている。 Next, the configuration of the filter cleaning device 20 will be described. As shown in FIG. 3, the filter cleaning device 20 includes, as main components, a dust box 22, a front brush (dust removing member) 23, a filter drive gear 24, a back roller (rotating member) 41 (see FIG. 5), and A filter support 25 and the like are provided.
　ダストボックス２２は、前面ブラシ２３によってフィルタ２１表面から除去された埃、塵、ゴミなどを、その内部に集積させる。ダストボックス２２は、フィルタ２１の表面側の前方部に、配置されている。そして、ダストボックス２２（具体的には、右側のダストボックス２２Ｒと左側のダストボックス２２Ｌ）は、フィルタ２１の左右方向（水平方向）に沿って、フィルタ２１の一端部から他端部に延びるように配置されている（図４参照）。 The dust box 22 accumulates dust, dust, dust and the like removed from the surface of the filter 21 by the front brush 23 in the interior. The dust box 22 is disposed in the front portion on the surface side of the filter 21. The dust box 22 (specifically, the right dust box 22R and the left dust box 22L) is disposed so as to extend from one end of the filter 21 to the other end along the horizontal direction (horizontal direction) of the filter 21. (See FIG. 4).
　ダストボックス２２は、フィルタ清掃装置２０に対して、取り外し可能に取り付けられている。具体的には、図５に示すように、ダストボックス２２は、フィルタ清掃装置２０のフィルタ支持体２５のダストボックス収容部２９に配置される。なお、ダストボックス２２には、ダストボックス２２を室内機１に対して固定させるためのロック機構（図示せず）が設けられている。そして、例えば、ダストボックス２２の上方中央部に設けられたロック解除レバー７１を、下方に下ろすことで、ロック機構のロックを解除することができる。これにより、使用者は、例えば、ダストボックス２２内の集積された埃を捨てる場合などに、ダストボックス２２を室内機１の本体部分から取り外すことができる。 The dust box 22 is detachably attached to the filter cleaning device 20. Specifically, as shown in FIG. 5, the dust box 22 is disposed in the dust box housing portion 29 of the filter support 25 of the filter cleaning device 20. The dust box 22 is provided with a lock mechanism (not shown) for fixing the dust box 22 to the indoor unit 1. For example, the lock release lever 71 provided at the upper center portion of the dust box 22 is lowered to release the lock mechanism. Thereby, the user can remove the dust box 22 from the main body part of the indoor unit 1 when, for example, throwing away the accumulated dust in the dust box 22.
　前面ブラシ２３は、細長い円筒形状（円柱形状）を有している。前面ブラシ２３は、ダストボックス２２の左右方向（水平方向）に沿って、各ダストボックス２２（２２Ｒおよび２２Ｌ）の一端部から他端部に延びるように配置されている。 The front brush 23 has an elongated cylindrical shape (columnar shape). The front brush 23 is disposed so as to extend from one end of each dust box 22 (22R and 22L) to the other end along the left-right direction (horizontal direction) of the dust box 22.
　前面ブラシ２３は、その先端（または表面）がフィルタ２１の表面と接触するように配置され、フィルタ２１上に付着した埃Ｄを掻き取る（図９（ａ）参照）。前面ブラシ２３は、例えば、適度な剛性を有する繊維（例えば、ナイロンなどの合成繊維、動物毛などの天然繊維）を複数本束ねて得られるブラシ毛２３ａ（図９（ａ）参照）、パイル状に起毛させた繊維（例えば、ナイロンなどの合成繊維、動物毛などの天然繊維）などで形成することができる。 The front brush 23 is arranged so that the tip (or surface) thereof is in contact with the surface of the filter 21 and scrapes off the dust D adhering to the filter 21 (see FIG. 9A). The front brush 23 includes, for example, brush hairs 23a (see FIG. 9A) obtained by bundling a plurality of fibers having appropriate rigidity (for example, synthetic fibers such as nylon and natural fibers such as animal hairs), a pile shape It is possible to form the fiber with raised fibers (for example, synthetic fiber such as nylon, natural fiber such as animal hair).
　また、前面ブラシ２３は、内部に回転するローラを有している。言い換えると、回転するローラの表面に前面ブラシ２３を構成するブラシ毛が埋め込まれている。そのため、ローラの回転に合わせて、ローラの表面に位置する前面ブラシ２３も回転する。ローラは、駆動モータ２３Ｍによって駆動される。駆動モータ２３Ｍは、正転のみ可能なモータであって、清掃運転中、前面ブラシ２３を矢印Ｒ１方向に回転させ続ける（図９（ａ）参照）。 Further, the front brush 23 has a roller that rotates inside. In other words, the bristle constituting the front brush 23 is embedded on the surface of the rotating roller. Therefore, the front brush 23 positioned on the surface of the roller also rotates in accordance with the rotation of the roller. The roller is driven by a drive motor 23M. The drive motor 23M is a motor that can perform only forward rotation, and continues to rotate the front brush 23 in the direction of the arrow R1 during the cleaning operation (see FIG. 9A).
　フィルタ駆動ギア２４は、フィルタ２１を間に挟んで、前面ブラシ２３と対向する位置に配置されている（図９（ａ）参照）。図６および図８などに示すように、フィルタ駆動ギア２４は、シャフト部２４ａとギア部（回転ギア）２４ｂとで構成されている。 The filter drive gear 24 is disposed at a position facing the front brush 23 with the filter 21 in between (see FIG. 9A). As shown in FIGS. 6 and 8, the filter drive gear 24 is composed of a shaft portion 24a and a gear portion (rotating gear) 24b.
　シャフト部２４ａは、フィルタ支持体２５に取り付けられており、フィルタ２１の左右方向（水平方向）に沿って配置されている（図６参照）。具体的には、右側フィルタ２１Ｒ側のシャフト部２４ａは、フィルタ支持体２５の右側壁部２６から中央壁部２７にまで延びている。また、左側フィルタ２１Ｌ側のシャフト部２４ａは、フィルタ支持体２５の中央壁部２７から左側壁部２８にまで延びている。シャフト部２４ａは、駆動モータ２４Ｍによって駆動される。これにより、フィルタ駆動ギア２４は回転する。 The shaft portion 24a is attached to the filter support 25 and is disposed along the left-right direction (horizontal direction) of the filter 21 (see FIG. 6). Specifically, the shaft portion 24 a on the right filter 21 </ b> R side extends from the right wall portion 26 of the filter support 25 to the central wall portion 27. The shaft portion 24 a on the left filter 21 </ b> L extends from the central wall portion 27 of the filter support 25 to the left wall portion 28. The shaft portion 24a is driven by a drive motor 24M. Thereby, the filter drive gear 24 rotates.
　シャフト部２４ａの両端部には、ギア部２４ｂが設けられている。駆動モータ２４Ｍによって回転するシャフト部２４ａに連動して、ギア部２４ｂも回転する。ギア部２４ｂは、フィルタ２１の縦枠５２Ｖに設けられた複数のラック（突起部）５４と対向するように配置されている。すなわち、フィルタ２１の各ラック５４は、フィルタ駆動ギア２４のギア部２４ｂの各歯と噛み合う。これにより、駆動モータ２４Ｍによってフィルタ駆動ギア２４が回転駆動されると、これに連動して、フィルタ２１がフィルタ支持体２５のガイド２５ａに沿って移動する。 The gear part 24b is provided in the both ends of the shaft part 24a. The gear portion 24b also rotates in conjunction with the shaft portion 24a rotated by the drive motor 24M. The gear portion 24 b is disposed so as to face a plurality of racks (projections) 54 provided on the vertical frame 52 </ b> V of the filter 21. That is, each rack 54 of the filter 21 meshes with each tooth of the gear portion 24 b of the filter drive gear 24. Thus, when the filter drive gear 24 is rotationally driven by the drive motor 24M, the filter 21 moves along the guide 25a of the filter support 25 in conjunction with this.
　駆動モータ２４Ｍは、正転・逆転切り換え可能なモータであって、上述の通り、フィルタ駆動ギア２４を回転させることによって、フィルタ２１をフィルタ支持体２５のガイド２５ａに沿って移動させる。なお、具体的には、駆動モータ２４Ｍが正転されると、フィルタ２１は、ガイド２５ａに沿って前方および下方に移動する（図９（ａ）の矢印Ｍ方向）。その結果、フィルタ２１上に堆積している塵埃が下から順に前面ブラシ２３によってダストボックス２２内に掻き落とされる（図９（ａ）参照）。一方、駆動モータ２４Ｍが逆転されると、フィルタ２１は、ガイド２５ａに沿って後方および上方に移動する。その結果、清掃済みのフィルタ２１が規定の位置に戻される。 The drive motor 24M is a motor that can switch between forward and reverse rotation, and moves the filter 21 along the guide 25a of the filter support 25 by rotating the filter drive gear 24 as described above. Specifically, when the drive motor 24M is rotated forward, the filter 21 moves forward and downward along the guide 25a (in the direction of arrow M in FIG. 9A). As a result, the dust accumulated on the filter 21 is scraped off into the dust box 22 by the front brush 23 in order from the bottom (see FIG. 9A). On the other hand, when the drive motor 24M is reversed, the filter 21 moves rearward and upward along the guide 25a. As a result, the cleaned filter 21 is returned to the specified position.
　背面ローラ４１は、フィルタ２１を間に挟んで前面ブラシ２３と対向する位置に配置されている（図９（ａ）参照）。例えば、背面ローラ４１は、フィルタ駆動ギア２４のシャフト部２４ａの前方側の斜め下方に配置されている。背面ローラ４１は、細長い円筒形状（円柱形状）を有している。背面ローラ４１は、フィルタ２１の左右方向（水平方向）に沿って、フィルタ２１の一端部側から他端部側に延びるように配置されている。なお、背面ローラ４１は、フィルタ駆動ギア２４のギア部２４ｂの内側に配置されている。 The back roller 41 is disposed at a position facing the front brush 23 with the filter 21 in between (see FIG. 9A). For example, the back roller 41 is disposed obliquely below the front side of the shaft portion 24 a of the filter drive gear 24. The back roller 41 has an elongated cylindrical shape (columnar shape). The back roller 41 is arranged so as to extend from one end side of the filter 21 to the other end side along the left-right direction (horizontal direction) of the filter 21. The back roller 41 is disposed inside the gear portion 24 b of the filter drive gear 24.
　背面ローラ４１は、長手方向の両端部にギア４１ａを有している。本実施形態では、背面ローラ４１は、フィルタ２１によって回転駆動される。すなわち、背面ローラ４１は、フィルタ２１の移動に連動して回転する。具体的には、背面ローラ４１の両端に設けられたギア４１ａが、フィルタ２１の縦枠５２Ｖに形成されたラック５４と噛み合うことで、フィルタ２１の移動に連動して背面ローラ４１が回転する。 The back roller 41 has gears 41a at both ends in the longitudinal direction. In the present embodiment, the back roller 41 is rotationally driven by the filter 21. That is, the back roller 41 rotates in conjunction with the movement of the filter 21. Specifically, the gears 41 a provided at both ends of the back roller 41 mesh with the racks 54 formed on the vertical frame 52 </ b> V of the filter 21, so that the back roller 41 rotates in conjunction with the movement of the filter 21.
　なお、ラック５４は、フィルタ駆動ギア２４のギア部２４ｂとも噛み合う。そのため、ラック５４は、フィルタ駆動ギア２４のギア部２４ｂと背面ローラ４１のギア４１ａとかみ合うために必要な幅（例えば、図１１などの幅Ｗ１）を有している。そして、上述したように、フィルタ２１は、フィルタ駆動ギア２４によって駆動されて移動する。すなわち、フィルタ駆動ギア２４の回転に合わせてラック５４が上下および前後方向に送られる。これにより、ラック５４と噛み合うもう一つのギア（すなわち、背面ローラ４１のギア４１ａ）も回転する。なお、ラック５４は、フィルタ駆動ギア２４のギア部２４ｂとかみ合う部分Ａと背面ローラ４１のギア４１ａとかみ合う部分Ｂとに分け、部分Ａと部分Ｂとの間に隙間を設けてもよい（図１１参照）。 The rack 54 also meshes with the gear portion 24b of the filter drive gear 24. Therefore, the rack 54 has a width (for example, a width W1 in FIG. 11 and the like) necessary for meshing with the gear portion 24b of the filter drive gear 24 and the gear 41a of the back roller 41. As described above, the filter 21 is moved by being driven by the filter drive gear 24. That is, the rack 54 is sent in the vertical and front-rear directions in accordance with the rotation of the filter drive gear 24. As a result, another gear meshing with the rack 54 (that is, the gear 41a of the back roller 41) also rotates. The rack 54 may be divided into a portion A that engages with the gear portion 24b of the filter drive gear 24 and a portion B that engages with the gear 41a of the back roller 41, and a gap may be provided between the portion A and the portion B (see FIG. 11).
　フィルタ支持体２５は、フィルタ２１を支持している。フィルタ支持体２５には、フィルタ清掃時に、フィルタ２１の移動を案内するガイド２５ａが備えられている。ガイド２５ａは、駆動モータ２４Ｍによってフィルタ２１を移動させる際において、フィルタ２１を規定の方向に沿って移動させるために形成されている。 The filter support 25 supports the filter 21. The filter support 25 is provided with a guide 25a for guiding the movement of the filter 21 during filter cleaning. The guide 25a is formed to move the filter 21 along a specified direction when the filter 21 is moved by the drive motor 24M.
　また、フィルタ支持体２５は、右側壁部２６、中央壁部２７、および左側壁部２８を有している。 The filter support 25 has a right side wall part 26, a central wall part 27, and a left side wall part 28.
　右側壁部２６は、フィルタ支持体２５の右側縁部において前後方向に延びる側壁である。この右側壁部２６の左側すなわち内側には、ガイド２５ａが配置されている。また、図４に示すように、右側壁部２６には、駆動モータ２３Ｍ、右側のフィルタ２１Ｒの移動を駆動する駆動モータ２４Ｍ、およびその他のフィルタ清掃装置駆動用の部材を搭載した駆動ユニット６０が設けられている。 The right side wall part 26 is a side wall extending in the front-rear direction at the right side edge part of the filter support 25. A guide 25a is disposed on the left side, that is, the inner side of the right wall portion 26. As shown in FIG. 4, the right wall portion 26 has a drive unit 60 mounted with a drive motor 23M, a drive motor 24M that drives the movement of the right filter 21R, and other members for driving the filter cleaning device. Is provided.
　左側壁部２８は、フィルタ支持体２５の左側縁部において前後方向に延びる側壁である。この左側壁部２８の右側すなわち内側には、ガイド２５ａが配置されている。また、図示はしていないが、左側壁部２８には、左側のフィルタ２１Ｌの移動を駆動する駆動モータ２４Ｍ、およびその他のフィルタ駆動用の部材を搭載した駆動ユニットが設けられている。なお、左側のダストボックス２２Ｌに配置される前面ブラシ２３の回転駆動は、右側壁部２６に設けられた駆動ユニット６０内の駆動モータ２３Ｍによって駆動される。この場合、駆動モータ２３Ｍの回転力は、右側のダストボックス２２Ｒに配置される前面ブラシ２３から、駆動ギアを介して、左側のダストボックス２２Ｌに配置される前面ブラシ２３に伝達される。 The left wall 28 is a side wall extending in the front-rear direction at the left edge of the filter support 25. A guide 25a is arranged on the right side of the left wall 28, that is, on the inner side. Although not shown, the left side wall portion 28 is provided with a drive motor 24M for driving the movement of the left filter 21L and a drive unit on which other filter driving members are mounted. The rotation of the front brush 23 arranged in the left dust box 22L is driven by a drive motor 23M in a drive unit 60 provided on the right wall portion 26. In this case, the rotational force of the drive motor 23M is transmitted from the front brush 23 disposed in the right dust box 22R to the front brush 23 disposed in the left dust box 22L via the drive gear.
　中央壁部２７は、フィルタ支持体２５の左右方向の略中央部において前後方向に延びる壁部である。そして、この中央壁部２７の両側には、ガイド２５ａがそれぞれ配置されている。なお、これらのガイド２５ａは、左側壁部２８のガイド２５ａおよび右側壁部２６のガイド２５ａと同一の形状を呈している。そして、左側のガイド２５ａは左側壁部２８のガイド２５ａと互いに対向し、右側のガイド２５ａは右側壁部２６のガイド２５ａと互いに対向している。すなわち、２つのフィルタ２１Ｒ・２１Ｌのうち一方（２１Ｌ）は中央壁部２７の左側のガイド２５ａと左側壁部２８のガイド２５ａとによって案内され、他方（２１Ｒ）は中央壁部２７の右側のガイド２５ａと右側壁部２６のガイド２５ａとによって案内されることになる。 The central wall portion 27 is a wall portion extending in the front-rear direction at a substantially central portion in the left-right direction of the filter support 25. Guides 25 a are arranged on both sides of the central wall portion 27. These guides 25a have the same shape as the guide 25a of the left side wall 28 and the guide 25a of the right side wall 26. The left guide 25a faces the guide 25a of the left wall 28 and the right guide 25a faces the guide 25a of the right wall 26. That is, one of the two filters 21R and 21L (21L) is guided by the left guide 25a of the central wall 27 and the guide 25a of the left wall 28, and the other (21R) is the right guide of the central wall 27. It will be guided by 25a and the guide 25a of the right side wall part 26.
　また、フィルタ支持体２５には、その前面側の下部に、ダストボックス２２を載置するためのダストボックス収容部２９が設けられている。ダストボックス収容部２９は、右側壁部２６と中央壁部２７との間、および、左側壁部２８と中央壁部２７との間にそれぞれ設けられている。右側壁部２６と中央壁部２７との間のダストボックス収容部２９には、ダストボックス２２Ｒが載置され、左側壁部２８と中央壁部２７との間のダストボックス収容部２９には、ダストボックス２２Ｌが載置される。 Further, the filter support 25 is provided with a dust box accommodating portion 29 for placing the dust box 22 at the lower part on the front side thereof. The dust box accommodating portions 29 are provided between the right side wall portion 26 and the central wall portion 27 and between the left side wall portion 28 and the central wall portion 27, respectively. A dust box 22R is placed in the dust box housing portion 29 between the right side wall portion 26 and the central wall portion 27, and a dust box 22L is placed in the dust box housing portion 29 between the left side wall portion 28 and the central wall portion 27. Placed.
　＜背面ローラについて＞
　続いて、背面ローラ４１のより具体的な構成について説明する。背面ローラ４１は、ギア４１ａ、ブラシ４１ｂ、および回転軸４１ｐなどを有している。 <Back roller>
Next, a more specific configuration of the back roller 41 will be described. The back roller 41 includes a gear 41a, a brush 41b, a rotating shaft 41p, and the like.
　上述したように、ギア４１ａは、背面ローラ４１の両端部に位置する。そして、図８に示すように、ギア４１ａは、フィルタ駆動ギア２４のギア部２４ｂの内側に位置する。 As described above, the gear 41a is located at both ends of the back roller 41. As shown in FIG. 8, the gear 41 a is located inside the gear portion 24 b of the filter drive gear 24.
　ブラシ４１ｂは、背面ローラ４１の表面に設けられている。ブラシ４１ｂは、例えば、適度な剛性を有する繊維（例えば、ナイロンなどの合成繊維、動物毛などの天然繊維）を複数本束ねて得られるブラシ毛で形成されている（図９（ａ）参照）。ブラシ４１ｂは、前面ブラシ２３と同じ素材で形成してもよい。 The brush 41b is provided on the surface of the back roller 41. The brush 41b is formed of, for example, brush hair obtained by bundling a plurality of fibers having appropriate rigidity (for example, synthetic fibers such as nylon and natural fibers such as animal hair) (see FIG. 9A). . The brush 41b may be formed of the same material as the front brush 23.
　背面ローラ４１の表面のブラシ４１ｂは、フィルタ２１の裏面と接触するように配置されている。そして、清掃運転中、フィルタ２１の移動に連動して背面ローラ４１は回転する。これにより、前面ブラシ２３と背面ローラ４１との間に配置されたフィルタ２１では、裏面側のブラシ４１ｂの作用によって、表面に付着している埃や塵などが、前方側へ押し出される。そのため、前面ブラシ２３によるフィルタ２１表面上での回転動作により、フィルタ２１上にある程度強力に付着している埃も掻き取ることができる。 The brush 41b on the surface of the back roller 41 is disposed so as to contact the back surface of the filter 21. During the cleaning operation, the back roller 41 rotates in conjunction with the movement of the filter 21. Thereby, in the filter 21 arrange | positioned between the front brush 23 and the back roller 41, the dust and dust adhering to the surface are pushed ahead by the effect | action of the brush 41b on the back side. Therefore, the dust adhered to the filter 21 to some extent can be scraped off by the rotation operation on the surface of the filter 21 by the front brush 23.
　回転軸４１ｐは、ブラシ４１ｂの内側に位置する。言い換えると、回転軸４１ｐの表面にブラシ４１ｂを構成するブラシ毛が埋め込まれている。回転軸４１ｐは、背面ローラ支持部４２に対して回転可能に取り付けられている。 Rotation shaft 41p is located inside brush 41b. In other words, the brush bristles constituting the brush 41b are embedded in the surface of the rotating shaft 41p. The rotating shaft 41p is rotatably attached to the back roller support portion.
　なお、本実施形態では、上記のようにフィルタ２１の裏面側に配置される回転部材として、表面にブラシ４１ｂを有する背面ローラ４１を用いている。しかし、本発明の一態様においては、フィルタ２１の裏面側に配置する回転部材の表面には、ブラシが設けられていなくてもよい。 In the present embodiment, the back roller 41 having the brush 41b on the surface is used as the rotating member disposed on the back side of the filter 21 as described above. However, in one aspect of the present invention, the brush does not have to be provided on the surface of the rotating member disposed on the back surface side of the filter 21.
　背面ローラ４１は、背面ローラ支持部４２によってフィルタ支持体２５に対して取り付けられている。背面ローラ支持部４２は、背面ローラ４１を、その両端部で支持している。図８に示すように、背面ローラ支持部４２は、フィルタ駆動ギア２４のギア部２４ｂと、背面ローラ４１のギア４１ａとの間に配置されている。図７には、背面ローラ支持部４２周辺の構成を示す。 The back roller 41 is attached to the filter support 25 by a back roller support portion 42. The back roller support portion 42 supports the back roller 41 at both ends thereof. As shown in FIG. 8, the back roller support portion 42 is disposed between the gear portion 24 b of the filter drive gear 24 and the gear 41 a of the back roller 41. FIG. 7 shows a configuration around the back roller support portion 42.
　図７に示すように、背面ローラ支持部４２は、フィルタ支持体２５に設けられたガイド２５ａに取り付けられている。そして、背面ローラ支持部４２は、ガイド２５ａの先端下方部から前方へ突出するように配置されている。背面ローラ４１の回転軸４１ｐは、背面ローラ支持部４２の先端部分に回転可能な状態で取り付けられている。 As shown in FIG. 7, the back roller support portion 42 is attached to a guide 25 a provided on the filter support 25. And the back roller support part 42 is arrange | positioned so that it may protrude ahead from the front-end | tip lower part of the guide 25a. The rotation shaft 41p of the back roller 41 is attached to the tip portion of the back roller support portion 42 in a rotatable state.
　なお、図９（ａ）に示すように、背面ローラ４１の径（断面径）は、フィルタ駆動ギア２４のギア部２４ｂの径よりも小さくなっている。そのため、フィルタ駆動ギア２４と一体的に背面ローラが設けられている場合と比較して、背面ローラの容積を小さくすることができる。そのため、本実施形態の構成によれば、吸込み口１４から室内機１内に取り込まれる空気の通路における背面ローラ４１の専有容積を小さくすることができる。したがって、空気通路が狭くなることにより、空気調和機の吸込み抵抗が増加し、空気調和機の送風性能低下につながる可能性を低減させることができる。 As shown in FIG. 9A, the diameter (cross-sectional diameter) of the back roller 41 is smaller than the diameter of the gear portion 24b of the filter drive gear 24. Therefore, the volume of the back roller can be reduced as compared with the case where the back roller is provided integrally with the filter drive gear 24. Therefore, according to the configuration of the present embodiment, the exclusive volume of the back roller 41 in the passage of the air taken into the indoor unit 1 from the suction port 14 can be reduced. Therefore, when the air passage is narrowed, the suction resistance of the air conditioner is increased, and the possibility that the air performance of the air conditioner is reduced can be reduced.
　また、本実施の形態では、背面ローラ４１の径（断面径）は、図７に示すようにフィルタ駆動ギア２４のギア部２４ｂの径の半分よりも小さくなっている。これにより、背面ローラ４１の本体部分（回転軸４１ｐ）がフィルタ駆動ギア２４のシャフト部２４ａに当たることを抑えることができる。なお、背面ローラ４１のブラシ毛の先端については、シャフト部２４ａにある程度当たってもよい。これに加え、側面視において、背面ローラ４１を、フィルタ駆動ギア２４のギア部２４ｂの内側に配置することができる。 Further, in the present embodiment, the diameter (cross-sectional diameter) of the back roller 41 is smaller than half the diameter of the gear portion 24b of the filter drive gear 24 as shown in FIG. Thereby, it can suppress that the main-body part (rotating shaft 41p) of the back roller 41 hits the shaft part 24a of the filter drive gear 24. FIG. The tip of the bristles of the back roller 41 may hit the shaft portion 24a to some extent. In addition, the back roller 41 can be disposed inside the gear portion 24b of the filter drive gear 24 in a side view.
　また、背面ローラ４１の配置位置は、フィルタ２１を間に挟んで前面ブラシ２３と対向する位置であればよい。これにより、フィルタ２１に強固に付着した埃などを、背面ローラ４１によって前面ブラシ２３側へ押し出すことができる。 Further, the arrangement position of the back roller 41 may be a position facing the front brush 23 with the filter 21 in between. Thereby, dust or the like firmly adhered to the filter 21 can be pushed out to the front brush 23 side by the back roller 41.
　なお、図９（ａ）に示すように、フィルタ清掃装置２０を側面側から見た場合に（側面視において）、背面ローラ４１は、フィルタ駆動ギア２４のギア部２４ｂの内側に位置することが好ましい。ここで、「背面ローラが、フィルタ駆動ギアのギア部の内側に位置する」とは、側面視において、フィルタ駆動ギアのギア部の回転軌跡の内側（回転軌跡の範囲内）に背面ローラが位置するように配置されていることを意味する。これにより、背面ローラ４１を設けることによって、吸込み口１４から取り込まれる空気の通路が狭められることを抑え、空気調和機の吸込み抵抗が増加することを抑えることができる。 9A, when the filter cleaning device 20 is viewed from the side surface side (in side view), the back roller 41 may be located inside the gear portion 24b of the filter drive gear 24. preferable. Here, “the back roller is located inside the gear portion of the filter drive gear” means that the back roller is located inside the rotation locus (within the range of the rotation locus) of the gear portion of the filter drive gear in a side view. It means that it is arranged. Thereby, by providing the back roller 41, it is possible to suppress the passage of the air taken in from the suction port 14 from being narrowed and to prevent the suction resistance of the air conditioner from increasing.
　＜フィルタおよび背面ローラの動作について＞
　続いて、フィルタ２１および背面ローラ４１の動作について、図９（ａ）などを参照しながら説明する。上述したように、フィルタ２１は、フィルタ駆動ギア２４の回転動作によって移動する。具体的には、フィルタ２１の縦枠５２Ｖに設けられた各ラック５４が、フィルタ駆動ギア２４のギア部２４ｂと噛み合うことで、ギア部２４ｂの回転（例えば、矢印Ｒ２方向の回転）に連動して、フィルタ２１が矢印Ｍ方向に移動する。 <Operation of filter and back roller>
Next, operations of the filter 21 and the back roller 41 will be described with reference to FIG. As described above, the filter 21 is moved by the rotation operation of the filter drive gear 24. Specifically, each rack 54 provided in the vertical frame 52V of the filter 21 meshes with the gear portion 24b of the filter drive gear 24, thereby interlocking with the rotation of the gear portion 24b (for example, the rotation in the arrow R2 direction). Thus, the filter 21 moves in the arrow M direction.
　また、フィルタの縦枠５２Ｖに設けられた各ラック５４は、ギア部２４ｂと隣り合うように位置する背面ローラ４１のギア４１ａとも噛み合う。そのため、フィルタ２１の移動動作に伴う各ラック５４の移動に連動して、ギア４１ａが回転する。これにより、背面ローラ４１も、フィルタ２１の動き（矢印Ｍ）に連動して、矢印Ｒ３方向に回転する。 Further, each rack 54 provided in the vertical frame 52V of the filter meshes with the gear 41a of the back roller 41 positioned adjacent to the gear portion 24b. Therefore, the gear 41a rotates in conjunction with the movement of each rack 54 accompanying the movement operation of the filter 21. As a result, the back roller 41 also rotates in the direction of arrow R3 in conjunction with the movement of the filter 21 (arrow M).
　なお、図９（ａ）に示す前面ブラシ２３、フィルタ駆動ギア２４および背面ローラ４１の回転方向は、本発明の一例である。そのため、前面ブラシ２３と、フィルタ駆動ギア２４および背面ローラ４１とは、互いに異なる方向に回転してもよい。この場合、ラック５４とギア４１ａとの間に一つギアを追加する、あるいは、ギア４１を追加のモータで駆動することになる。ただし、このようにした場合に、同方向に回転させる場合と比べて、フィルタの搬送により大きな力が必要となる。 The rotational directions of the front brush 23, the filter drive gear 24, and the back roller 41 shown in FIG. 9A are examples of the present invention. Therefore, the front brush 23, the filter drive gear 24, and the back roller 41 may rotate in different directions. In this case, one gear is added between the rack 54 and the gear 41a, or the gear 41 is driven by an additional motor. However, in this case, a greater force is required for transporting the filter than when rotating in the same direction.
　また、フィルタ駆動ギア２４の回転方向と背面ローラ４１の回転方向とは、同じ方向とすることが好ましい。これにより、フィルタ２１の裏面と背面ローラ４１上のブラシ４１ｂとの間の摩擦を抑えることができる。 Further, it is preferable that the rotation direction of the filter drive gear 24 and the rotation direction of the back roller 41 be the same direction. Thereby, the friction between the back surface of the filter 21 and the brush 41b on the back roller 41 can be suppressed.
　さらに、フィルタ駆動ギア２４のギア部２４ｂの各歯のピッチＰ１と、背面ローラ４１のギア４１ａの各歯のピッチＰ２とは、各ラック５４間の間隔に合わせて、略同一にすることが好ましい（図９（ｂ）参照）。これにより、フィルタ２１の移動速度と、背面ローラ４１の回転速度を合わせることができる。そのため、フィルタ２１上に発生する静電気の量を抑えることができる。 Further, the pitch P1 of each tooth of the gear portion 24b of the filter drive gear 24 and the pitch P2 of each tooth of the gear 41a of the back roller 41 are preferably substantially the same in accordance with the interval between the racks 54. (See FIG. 9B). Thereby, the moving speed of the filter 21 and the rotational speed of the back roller 41 can be matched. Therefore, the amount of static electricity generated on the filter 21 can be suppressed.
　なお、本実施形態では、上述のように、フィルタ２１の縦枠５２Ｖに設けられた各ラック５４は、ギア部２４ｂおよびギア４１ａの両方に噛み合う。したがって、ラック５４の水平方向の幅Ｗ１は、一般的なフィルタ（例えば、図１６に示すフィルタ２２１）のラック２５４の幅Ｗ２と比較して大きくなっている。 In the present embodiment, as described above, each rack 54 provided in the vertical frame 52V of the filter 21 meshes with both the gear portion 24b and the gear 41a. Therefore, the horizontal width W1 of the rack 54 is larger than the width W2 of the rack 254 of a general filter (for example, the filter 221 shown in FIG. 16).
　なお、本実施形態では、背面ローラ４１の回転は、フィルタ２１のラック５４を介して伝達される駆動モータ２４Ｍの駆動力を用いて行われる。しかし、本発明の態様はこのような構成に限定はされない。例えば、背面ローラ４１に専用の駆動モータを設け、フィルタ２１の移動とは別の駆動系によって背面ローラ４１を回転させてもよい。 In this embodiment, the back roller 41 is rotated by using the driving force of the driving motor 24M transmitted through the rack 54 of the filter 21. However, the aspect of the present invention is not limited to such a configuration. For example, a dedicated drive motor may be provided on the back roller 41, and the back roller 41 may be rotated by a drive system different from the movement of the filter 21.
　以上のように、本実施形態のフィルタ清掃装置２０は、前面ブラシ２３（埃取り部材）に沿うようにフィルタ２１を移動させるフィルタ駆動ギア２４（フィルタ駆動部）と、フィルタ２１を間に挟んで前面ブラシ２３と対向する位置に配置され、フィルタ２１の移動に連動して回転する背面ローラ４１（回転部材）とを備えている。この構成によれば、フィルタ駆動ギア２４（フィルタ駆動部）と背面ローラ４１（回転部材）とを別々の部材で構成することができる。そのため、フィルタ２１を挟んで前面ブラシ２３（埃取り部材）と対向する位置に配置される回転部材の径を小さくすることができる。したがって、フィルタ２１を通して外部の空気を取り込む際の空気調和機の吸込み抵抗の増加を抑えることができる。 As described above, the filter cleaning device 20 of the present embodiment sandwiches the filter 21 between the filter drive gear 24 (filter drive unit) that moves the filter 21 along the front brush 23 (dust removing member). A back roller 41 (rotating member) that is disposed at a position facing the front brush 23 and rotates in conjunction with the movement of the filter 21 is provided. According to this structure, the filter drive gear 24 (filter drive part) and the back roller 41 (rotating member) can be comprised by a separate member. Therefore, the diameter of the rotating member arranged at a position facing the front brush 23 (dust removing member) across the filter 21 can be reduced. Therefore, an increase in the suction resistance of the air conditioner when taking in external air through the filter 21 can be suppressed.
　〔第２の実施形態〕
　本発明の第２の実施形態について、図１２から図１４を参照しながら説明する。第２の実施形態では、空気調和機の室内機１内のフィルタ清掃装置の構成が、第１の実施形態とは異なっている。それ以外の構成については、第１の実施形態と同じ構成が適用できる。そこで、以下では、第２の実施形態にかかるフィルタ清掃装置１２０の構成を中心に説明する。第１の実施形態と同じ構成が適用できる構成部材については、第１の実施形態と同じ符号を付し、その説明を省略する。 [Second Embodiment]
A second embodiment of the present invention will be described with reference to FIGS. In 2nd Embodiment, the structure of the filter cleaning apparatus in the indoor unit 1 of an air conditioner differs from 1st Embodiment. About the other structure, the same structure as 1st Embodiment is applicable. Therefore, hereinafter, the configuration of the filter cleaning device 120 according to the second embodiment will be mainly described. About the structural member which can apply the same structure as 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected and the description is abbreviate | omitted.
　図１２には、第２の実施形態にかかる室内機１に備えられているフィルタ清掃装置１２０の一部分を示す。フィルタ清掃装置１２０は、主な構成部材として、ダストボックス２２、前面ブラシ（埃取り部材）２３、フィルタ駆動ギア１２４、背面ローラ（回転部材）１４１、およびフィルタ支持体１２５などを備えている。ダストボックス２２、前面ブラシ（埃取り部材）２３、およびフィルタ支持体１２５（フィルタ支持体２５に対応）については、第１の実施形態と同様の構成が適用できる。 FIG. 12 shows a part of the filter cleaning device 120 provided in the indoor unit 1 according to the second embodiment. The filter cleaning device 120 includes a dust box 22, a front brush (dust removing member) 23, a filter drive gear 124, a back roller (rotating member) 141, a filter support 125, and the like as main components. The same configuration as that of the first embodiment can be applied to the dust box 22, the front brush (dust removing member) 23, and the filter support 125 (corresponding to the filter support 25).
　第１の実施形態と同様に、フィルタ駆動ギア１２４は、フィルタ１２１を間に挟んで、前面ブラシ２３と対向する位置に配置されている。図１２に示すように、フィルタ駆動ギア１２４は、シャフト部１２４ａとギア部（回転ギア）１２４ｂとで構成されている。 As in the first embodiment, the filter drive gear 124 is disposed at a position facing the front brush 23 with the filter 121 interposed therebetween. As shown in FIG. 12, the filter drive gear 124 includes a shaft portion 124a and a gear portion (rotating gear) 124b.
　シャフト部１２４ａは、フィルタ１２１の左右方向（水平方向）に沿って配置されている。シャフト部１２４ａは、駆動モータ２４Ｍによって駆動される。これにより、フィルタ駆動ギア１２４は回転する。 The shaft portion 124a is disposed along the left-right direction (horizontal direction) of the filter 121. The shaft portion 124a is driven by the drive motor 24M. Thereby, the filter drive gear 124 rotates.
　シャフト部１２４ａの両端部には、ギア部１２４ｂが設けられている。駆動モータ２４Ｍによって回転するシャフト部１２４ａに連動して、ギア部１２４ｂも回転する。ギア部１２４ｂは、フィルタ１２１の縦枠１５２Ｖに設けられた複数のラック（突起部）１５４と対向するように配置されている。すなわち、フィルタ１２１の各ラック１５４は、フィルタ駆動ギア１２４のギア部１２４ｂの各歯と噛み合う。これにより、駆動モータ２４Ｍによってフィルタ駆動ギア１２４が回転駆動されると、これに連動して、フィルタ１２１がフィルタ支持体１２５のガイド２５ａに沿って移動する。 Gear portions 124b are provided at both ends of the shaft portion 124a. The gear portion 124b also rotates in conjunction with the shaft portion 124a that is rotated by the drive motor 24M. The gear portion 124 b is disposed so as to face a plurality of racks (projections) 154 provided on the vertical frame 152 </ b> V of the filter 121. That is, each rack 154 of the filter 121 meshes with each tooth of the gear portion 124b of the filter drive gear 124. Thus, when the filter drive gear 124 is rotationally driven by the drive motor 24M, the filter 121 moves along the guide 25a of the filter support 125 in conjunction with this.
　背面ローラ１４１は、フィルタ１２１を間に挟んで前面ブラシ２３と対向する位置に配置されている。例えば、図１２に示すように、背面ローラ１４１は、フィルタ駆動ギア１２４のシャフト部１２４ａの前方側の斜め下方に配置されている。背面ローラ１４１は、細長い円筒形状（円柱形状）を有している。背面ローラ１４１は、フィルタ１２１の左右方向（水平方向）に沿って、フィルタ１２１の一端部から他端部に延びるように配置されている。 The back roller 141 is disposed at a position facing the front brush 23 with the filter 121 interposed therebetween. For example, as shown in FIG. 12, the back roller 141 is disposed obliquely below the front side of the shaft portion 124 a of the filter drive gear 124. The back roller 141 has an elongated cylindrical shape (columnar shape). The back roller 141 is disposed so as to extend from one end of the filter 121 to the other end along the left-right direction (horizontal direction) of the filter 121.
　背面ローラ１４１は、長手方向の略中央部にギア１４１ａを有している。また、第１の実施形態と同様に、背面ローラ１４１の表面には、ブラシ１４１ｂが設けられている。また、第１の実施形態と同様に、背面ローラ１４１は、背面ローラ支持部１４２によってフィルタ支持体１２５に対して取り付けられている。なお、図示はしていないが、ブラシ１４１ｂの内側には、回転軸が設けられている。そして、回転軸は、背面ローラ支持部１４２に対して回転可能に取り付けられている。これにより、背面ローラ１４１は回転する。 The back roller 141 has a gear 141a at a substantially central portion in the longitudinal direction. As in the first embodiment, a brush 141b is provided on the surface of the back roller 141. Similarly to the first embodiment, the back roller 141 is attached to the filter support 125 by the back roller support portion 142. Although not shown, a rotating shaft is provided inside the brush 141b. The rotation shaft is rotatably attached to the back roller support portion 142. As a result, the back roller 141 rotates.
　第１の実施形態と同様に、背面ローラ１４１は、フィルタ１２１によって回転駆動される。すなわち、背面ローラ１４１は、フィルタ１２１の移動に連動して回転する。具体的には、背面ローラ１４１に設けられたギア１４１ａが、フィルタ１２１に形成された第２のラック１５５と噛み合うことで、フィルタ１２１の移動に連動して背面ローラ１４１が回転する。 As in the first embodiment, the back roller 141 is rotationally driven by the filter 121. That is, the back roller 141 rotates in conjunction with the movement of the filter 121. Specifically, the gear 141 a provided on the back roller 141 meshes with the second rack 155 formed on the filter 121, so that the back roller 141 rotates in conjunction with the movement of the filter 121.
　続いて、本実施形態のフィルタ清掃装置１２０に備えられているフィルタ１２１の構成について説明する。図１３および図１４には、フィルタ１２１の構成を示す。フィルタ１２１は、メッシュ部１５１と、メッシュ部１５１の周囲を取り囲む枠体（枠部）１５２とで構成されている。 Subsequently, the configuration of the filter 121 provided in the filter cleaning device 120 of the present embodiment will be described. 13 and 14 show the configuration of the filter 121. FIG. The filter 121 includes a mesh portion 151 and a frame body (frame portion) 152 that surrounds the mesh portion 151.
　枠体１５２は、縦方向（移動方向に平行な方向）の枠部分である縦枠１５２Ｖと、横方向（移動方向に交差する方向）の枠部分である横枠１５２Ｈとからなる。フィルタ１２１は、フィルタ支持体１２５に着脱可能に支持されている。 The frame body 152 includes a vertical frame 152V that is a frame portion in the vertical direction (direction parallel to the moving direction) and a horizontal frame 152H that is a frame portion in the horizontal direction (direction intersecting the moving direction). The filter 121 is detachably supported on the filter support 125.
　メッシュ部１５１は、例えば、ポリエチレンテレフタレートで網目状に形成され、枠体５２は、例えば、ポリプロピレン樹脂などの合成樹脂で形成される。またあるいは、メッシュ部１５１と枠体１５２とは、ポリプロピレン樹脂等の合成樹脂により一体的に成形されてもよい。 The mesh portion 151 is formed in a mesh shape with, for example, polyethylene terephthalate, and the frame body 52 is formed with a synthetic resin such as polypropylene resin. Alternatively, the mesh portion 151 and the frame body 152 may be integrally formed of synthetic resin such as polypropylene resin.
　また、枠体１５２は、複数のリブ１５３を有している。各リブ１５３は、枠体１５２の内部を縦または横に略等間隔に延びており、これにより、メッシュ部１５１の表面は碁盤目状に区画される。この構成により、フィルタ１２１の強度が高まる。 The frame body 152 has a plurality of ribs 153. The ribs 153 extend in the frame body 152 vertically or horizontally at substantially equal intervals, whereby the surface of the mesh portion 151 is partitioned in a grid pattern. With this configuration, the strength of the filter 121 is increased.
　リブ１５３は、フィルタ１２１の裏面側に設けられている。本実施形態では、縦方向（移動方向に平行な方向）に延びるリブ１５３のうちの中央に位置するリブ１５３Ｃに、複数の第２のラック（突起部）１５５が形成されている。第２のラック１５５は、背面ローラ１４１に設けられたギア１４１ａと対応する位置に配置され、ギア１４１ａと噛み合う。これにより、フィルタ１２１が移動することによって第２のラック１５５と噛み合うギア１４１ａが回転する。 The rib 153 is provided on the back side of the filter 121. In the present embodiment, a plurality of second racks (projections) 155 are formed on the rib 153C located at the center of the ribs 153 extending in the vertical direction (direction parallel to the moving direction). The second rack 155 is disposed at a position corresponding to the gear 141a provided on the back roller 141, and meshes with the gear 141a. Thereby, the gear 141a which meshes with the 2nd rack 155 rotates by the filter 121 moving.
　また、枠体１５２の縦枠１５２Ｖの裏面側には、複数のラック（突起部）１５４が形成されている。ラック１５４は、フィルタ１２１の移動を駆動するフィルタ駆動ギア１２４と噛み合う。そして、駆動モータ２４Ｍによってフィルタ駆動ギア１２４が回転駆動されると、これに連動して、フィルタ１２１がフィルタ支持体１２５のガイド２５ａに沿って移動する。すなわち、駆動モータ２４Ｍによってフィルタ駆動ギア１２４が回転駆動されると、フィルタ１２１がフィルタ支持体１２５のガイド２５ａに沿って、室内機１内を前後方向に移動するとともに、室内機１内を上下方向に移動する。 A plurality of racks (projections) 154 are formed on the back side of the vertical frame 152V of the frame 152. The rack 154 meshes with a filter drive gear 124 that drives the movement of the filter 121. When the filter drive gear 124 is rotationally driven by the drive motor 24M, the filter 121 moves along the guide 25a of the filter support 125 in conjunction with this. That is, when the filter drive gear 124 is rotationally driven by the drive motor 24M, the filter 121 moves in the front-rear direction in the indoor unit 1 along the guide 25a of the filter support 125 and moves in the vertical direction in the indoor unit 1. Move to.
　以上のように、本実施形態にかかるフィルタ清掃装置１２０では、フィルタ１２１の中央部において縦方向に延びるリブ１５３Ｃに形成された第２のラック１５５によって、背面ローラ１４１の回転が行われる。この場合、背面ローラ１４１には、１個のギア１４１ａのみを設ければよい。これにより、フィルタ１２１の移動に連動して、背面ローラ１４１を回転させることができる。 As described above, in the filter cleaning device 120 according to the present embodiment, the back roller 141 is rotated by the second rack 155 formed on the rib 153 </ b> C extending in the vertical direction at the center of the filter 121. In this case, only one gear 141a may be provided on the back roller 141. Thereby, the back roller 141 can be rotated in conjunction with the movement of the filter 121.
　このように、本発明の一態様にかかるフィルタ清掃装置では、第１の実施形態のように、フィルタ２１の縦枠５２Ｖに形成されたラック５４が、背面ローラ４１のギア４１ａと噛み合うことによって、背面ローラ４１を回転させてもよい。また、第２の実施形態のように、フィルタ１２１の縦枠１５２Ｖに形成されたラック１５４とは別に、例えば、フィルタ１２１のリブ１５３に第２のラック１５５を形成してもよい。そして、第２のラック１５５が、背面ローラ１４１のギア１４１ａと噛み合うことによって、背面ローラ１４１を回転させてもよい。第２の実施形態の構成によれば、フィルタ１２１の縦枠１５２Ｖの幅を、第１の実施形態のフィルタ２１の縦枠５２Ｖの幅Ｗ１と比較して、小さくすることができる。 Thus, in the filter cleaning device according to one aspect of the present invention, the rack 54 formed on the vertical frame 52V of the filter 21 meshes with the gear 41a of the back roller 41 as in the first embodiment. The back roller 41 may be rotated. Further, as in the second embodiment, for example, the second rack 155 may be formed on the rib 153 of the filter 121 separately from the rack 154 formed on the vertical frame 152V of the filter 121. Then, the back roller 141 may be rotated by the second rack 155 meshing with the gear 141 a of the back roller 141. According to the configuration of the second embodiment, the width of the vertical frame 152V of the filter 121 can be made smaller than the width W1 of the vertical frame 52V of the filter 21 of the first embodiment.
　なお、本実施形態では、背面ローラ１４１のギア１４１ａは、背面ローラ１４１の長手方向の略中央部に１個形成されている。しかし、本発明の態様はこの構成に限定はされない。他の構成例では、背面ローラ１４１のギア１４１ａは、背面ローラ１４１の長手方向の略中央部の両脇に２個以上形成することもできる。この場合、ギア１４１ａは、フィルタ１２１のリブ１５３と対応する位置に形成することが好ましい。これにより、リブ１５３上に、ギア１４１ａと噛み合う第２のラック１５５を形成することができる。 In this embodiment, one gear 141a of the back roller 141 is formed at a substantially central portion in the longitudinal direction of the back roller 141. However, the aspect of the present invention is not limited to this configuration. In another configuration example, two or more gears 141 a of the back roller 141 may be formed on both sides of the substantially central portion of the back roller 141 in the longitudinal direction. In this case, the gear 141a is preferably formed at a position corresponding to the rib 153 of the filter 121. As a result, the second rack 155 that meshes with the gear 141 a can be formed on the rib 153.
　〔第３の実施形態〕
　本発明の第３の実施形態について、図１５および図１６を参照しながら説明する。第３の実施形態では、空気調和機の室内機１内のフィルタ清掃装置の構成が、第１の実施形態とは異なっている。それ以外の構成については、第１の実施形態と同じ構成が適用できる。そこで、以下では、第３の実施形態にかかるフィルタ清掃装置２２０の構成を中心に説明する。第１の実施形態と同じ構成が適用できる構成部材については、第１の実施形態と同じ符号を付し、その説明を省略する。 [Third Embodiment]
A third embodiment of the present invention will be described with reference to FIGS. 15 and 16. In 3rd Embodiment, the structure of the filter cleaning apparatus in the indoor unit 1 of an air conditioner differs from 1st Embodiment. About the other structure, the same structure as 1st Embodiment is applicable. Therefore, hereinafter, the configuration of the filter cleaning device 220 according to the third embodiment will be mainly described. About the structural member which can apply the same structure as 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected and the description is abbreviate | omitted.
　図１５には、第３の実施形態にかかる室内機１に備えられているフィルタ清掃装置２２０の一部分を示す。フィルタ清掃装置２２０は、主な構成部材として、ダストボックス２２、前面ブラシ（埃取り部材）２３、フィルタ駆動ギア２２４、背面ローラ（回転部材）２４１、およびフィルタ支持体２２５などを備えている。ダストボックス２２、前面ブラシ（埃取り部材）２３、およびフィルタ支持体２２５（フィルタ支持体２５に対応）については、第１の実施形態と同様の構成が適用できる。 FIG. 15 shows a part of the filter cleaning device 220 provided in the indoor unit 1 according to the third embodiment. The filter cleaning device 220 includes a dust box 22, a front brush (dust removing member) 23, a filter drive gear 224, a back roller (rotating member) 241, a filter support 225, and the like as main components. The same configuration as that of the first embodiment can be applied to the dust box 22, the front brush (dust removing member) 23, and the filter support 225 (corresponding to the filter support 25).
　第１の実施形態と同様に、フィルタ駆動ギア２２４は、フィルタ２２１を間に挟んで、前面ブラシ２３と対向する位置に配置されている。図１５に示すように、フィルタ駆動ギア２２４は、シャフト部２２４ａとギア部（回転ギア）２２４ｂとで構成されている。 As in the first embodiment, the filter drive gear 224 is disposed at a position facing the front brush 23 with the filter 221 interposed therebetween. As shown in FIG. 15, the filter drive gear 224 includes a shaft portion 224a and a gear portion (rotating gear) 224b.
　シャフト部２２４ａは、フィルタ２２１の左右方向（水平方向）に沿って配置されている。シャフト部２２４ａは、駆動モータ２４Ｍによって駆動される。これにより、フィルタ駆動ギア２２４は回転する。 The shaft portion 224a is disposed along the left-right direction (horizontal direction) of the filter 221. The shaft portion 224a is driven by the drive motor 24M. As a result, the filter drive gear 224 rotates.
　シャフト部２２４ａの両端部には、ギア部２２４ｂが設けられている。駆動モータ２４Ｍによって回転するシャフト部２２４ａに連動して、ギア部２２４ｂも回転する。ギア部２２４ｂは、フィルタ２２１の縦枠２５２Ｖに設けられた複数のラック（突起部）２５４と対向するように配置されている。すなわち、フィルタ２２１の各ラック２５４は、フィルタ駆動ギア２２４のギア部２２４ｂの各歯と噛み合う。これにより、駆動モータ２４Ｍによってフィルタ駆動ギア２２４が回転駆動されると、これに連動して、フィルタ２２１がフィルタ支持体２２５のガイド２５ａに沿って移動する。 The gear part 224b is provided in the both ends of the shaft part 224a. The gear portion 224b also rotates in conjunction with the shaft portion 224a rotated by the drive motor 24M. The gear portion 224b is disposed so as to face a plurality of racks (projections) 254 provided on the vertical frame 252V of the filter 221. That is, each rack 254 of the filter 221 meshes with each tooth of the gear portion 224b of the filter drive gear 224. Accordingly, when the filter drive gear 224 is rotationally driven by the drive motor 24M, the filter 221 moves along the guide 25a of the filter support 225 in conjunction with this.
　背面ローラ２４１は、フィルタ２２１を間に挟んで前面ブラシ２３と対向する位置に配置されている。例えば、図１５に示すように、背面ローラ２４１は、フィルタ駆動ギア２２４のシャフト部２２４ａの前方側の斜め下方に配置されている。背面ローラ２４１は、細長い円筒形状（円柱形状）を有している。背面ローラ２４１は、フィルタ２２１の左右方向（水平方向）に沿って、フィルタ２２１の一端部から他端部に延びるように配置されている。 The back roller 241 is disposed at a position facing the front brush 23 with the filter 221 in between. For example, as shown in FIG. 15, the back roller 241 is disposed obliquely below the front side of the shaft portion 224 a of the filter drive gear 224. The back roller 241 has an elongated cylindrical shape (columnar shape). The back roller 241 is disposed so as to extend from one end of the filter 221 to the other end along the left-right direction (horizontal direction) of the filter 221.
　第１の実施形態と同様に、背面ローラ２４１の表面には、ブラシ２４１ｂが設けられている。また、第１の実施形態と同様に、背面ローラ２４１は、背面ローラ支持部２４２によってフィルタ支持体２２５に対して取り付けられている。なお、図示はしていないが、ブラシ２４１ｂの内側には、回転軸が設けられている。そして、回転軸は、背面ローラ支持部２４２に対して回転可能に取り付けられている。これにより、背面ローラ２４１は回転する。 As in the first embodiment, a brush 241b is provided on the surface of the back roller 241. As in the first embodiment, the back roller 241 is attached to the filter support 225 by the back roller support 242. Although not shown, a rotation shaft is provided inside the brush 241b. The rotation shaft is rotatably attached to the back roller support portion 242. Thereby, the back roller 241 rotates.
　本実施形態にかかる背面ローラ２４１には、第１および第２の実施形態にかかる背面ローラにおいて設けられているようなギアは設けられていない。本実施形態では、ブラシ２４１ｂとフィルタ２２１の裏面とが接触することによって生じる摩擦力によって、背面ローラ２４１が回転する。これにより、背面ローラ２４１は、フィルタ２２１の移動に連動して回転する。 The rear roller 241 according to the present embodiment is not provided with a gear that is provided in the rear roller according to the first and second embodiments. In the present embodiment, the back roller 241 is rotated by the frictional force generated by the contact between the brush 241b and the back surface of the filter 221. Thereby, the back roller 241 rotates in conjunction with the movement of the filter 221.
　続いて、本実施形態のフィルタ清掃装置２２０に備えられているフィルタ２２１の構成について説明する。図１６には、フィルタ２２１の構成を示す。フィルタ２２１は、メッシュ部２５１と、メッシュ部２５１の周囲を取り囲む枠体（枠部）２５２とで構成されている。メッシュ部２５１は、第１の実施形態のメッシュ部５１と同様の構成が適用できる。 Subsequently, the configuration of the filter 221 provided in the filter cleaning device 220 of the present embodiment will be described. FIG. 16 shows the configuration of the filter 221. The filter 221 includes a mesh part 251 and a frame body (frame part) 252 that surrounds the mesh part 251. A configuration similar to that of the mesh unit 51 of the first embodiment can be applied to the mesh unit 251.
　枠体２５２は、縦方向（移動方向に平行な方向）の枠部分である縦枠２５２Ｖと、横方向（移動方向に交差する方向）の枠部分である横枠２５２Ｈとからなる。フィルタ２２１は、フィルタ支持体２２５に着脱可能に支持されている。 The frame body 252 includes a vertical frame 252V that is a frame portion in the vertical direction (direction parallel to the moving direction) and a horizontal frame 252H that is a frame portion in the horizontal direction (direction intersecting the moving direction). The filter 221 is detachably supported by the filter support 225.
　また、枠体２５２は、複数のリブ２５３を有している。リブ２５３は、第１の実施形態のリブ５３と同様の構成が適用できる。 Further, the frame body 252 has a plurality of ribs 253. The rib 253 can be configured similarly to the rib 53 of the first embodiment.
　枠体２５２の縦枠２５２Ｖの裏面側には、複数のラック（突起部）２５４が形成されている。このようなラック２５４は、フィルタ２２１の移動を駆動するフィルタ駆動ギア２２４と噛み合う。そして、駆動モータ２４Ｍによってフィルタ駆動ギア２２４が回転駆動されると、これに連動して、フィルタ２２１がフィルタ支持体２２５のガイド２５ａに沿って移動する。すなわち、駆動モータ２４Ｍによってフィルタ駆動ギア２２４が回転駆動されると、フィルタ２２１がフィルタ支持体２２５のガイド２５ａに沿って、室内機１内を前後方向に移動するとともに、室内機１内を上下方向に移動する。 A plurality of racks (projections) 254 are formed on the back side of the vertical frame 252V of the frame body 252. Such a rack 254 meshes with a filter drive gear 224 that drives the movement of the filter 221. When the filter drive gear 224 is rotationally driven by the drive motor 24M, the filter 221 moves along the guide 25a of the filter support 225 in conjunction with this. That is, when the filter drive gear 224 is rotationally driven by the drive motor 24M, the filter 221 moves in the front-rear direction in the indoor unit 1 along the guide 25a of the filter support 225, and in the vertical direction in the indoor unit 1. Move to.
　なお、本実施形態では、ラック２５４は、フィルタ駆動ギア２２４のギア部２２４ｂのみと噛み合う。そのため、ギア部２４ｂおよびギア４１ａの両方と噛み合う第１の実施形態のフィルタ２１と比較して、ラック２５４の水平方向の幅Ｗ２を小さくすることができる。これにより、空気調和機の吸込み抵抗の増加を抑えることができる。 In this embodiment, the rack 254 meshes only with the gear portion 224b of the filter drive gear 224. Therefore, the horizontal width W2 of the rack 254 can be reduced as compared with the filter 21 of the first embodiment that meshes with both the gear portion 24b and the gear 41a. Thereby, the increase in the suction resistance of an air conditioner can be suppressed.
　以上のように、本実施形態にかかるフィルタ清掃装置２２０では、背面ローラ２４１の表面に設けられたブラシ２４１ｂとフィルタ２２１の裏面とが接触することによって、背面ローラ２４１が回転する。これにより、フィルタ２２１の移動に連動して、背面ローラ２４１を回転させることができる。 As described above, in the filter cleaning device 220 according to the present embodiment, the back roller 241 rotates when the brush 241b provided on the surface of the back roller 241 contacts the back surface of the filter 221. Thereby, the back roller 241 can be rotated in conjunction with the movement of the filter 221.
　今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。また、本明細書で説明した異なる実施形態の構成を互いに組み合わせて得られる構成についても、本発明の範疇に含まれる。 The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. Further, configurations obtained by combining the configurations of the different embodiments described in this specification with each other are also included in the scope of the present invention.
