Description

この発明は、空気調和機に関するもので、特にエアフィルタの自動清掃機能を供えた空気調和機に関するものである。 The present invention relates to an air conditioner, and more particularly to an air conditioner provided with an automatic cleaning function of an air filter.

従来、空気調和機に於いては、送風ファンにより吸い込んだ室内空気を、熱交換器に通過させることにより冷却または加熱して室内へと返流させるが、空気中に浮遊する塵埃が熱交換器を汚染するのを防止するため、熱交換器の前面側にエアフィルタが設けられている。このフィルタに塵埃が付着して目詰まりが生じ通風抵抗が増大すると、熱交換が妨げられるために空気調和機の空調能力が低下すると共に、消費電力が増大する。このような不都合を解消するため、フィルタの自動清掃機能を供えた空気調和機が種々提案されている。 Conventionally, in an air conditioner, indoor air sucked by a blower fan is cooled or heated by passing through a heat exchanger to be returned to the room, but dust floating in the air is exchanged with the heat exchanger. An air filter is provided on the front side of the heat exchanger in order to prevent air pollution. If dust adheres to this filter and becomes clogged to increase ventilation resistance, heat exchange is hindered, so that the air conditioning capacity of the air conditioner is reduced and power consumption is increased. In order to eliminate such inconvenience, various air conditioners having an automatic filter cleaning function have been proposed.

フィルタを自動的に清掃する場合、フィルタの全面を清掃ブラシで掃除するため、フィルタと清掃ブラシとの少なくともいずれか一方を移動させる必要がある。
フィルタを移動させる方式では、外枠の上面や前面に吸込口を備え、この吸込口の内面側に沿って配された板状のフィルターと、このフィルターを移動させる移動経路と、この移動経路の途中に配され前記フィルターを清掃する清掃手段と、前記移動経路内のフィルタを移動させる移送手段とを備え、前記移動経路は吸込口の内面側に沿って形成されると共に、内部に配置される熱交換器との間の前方側空間部でＵ字状に折り返して形成され、更に、フィルタを通常使用位置に保持する通常ガイド部と、この通常ガイド部の一端部に連なると共に、湾曲部に対向して接触する回転ブラシと、このブラシで掻き取ったゴミを蓄えるダストボックスとを備え、前記フィルタを移動させることによって、通常ガイド部の一端部に位置するフィルタの先端部が、通常ガイド部から湾曲部でＵ字状に折返されて前記ブラシによって自動清掃を行うものがある。（例えば、特許文献１参照） When cleaning the filter automatically, since the entire surface of the filter is cleaned with the cleaning brush, it is necessary to move at least one of the filter and the cleaning brush.
In the method of moving the filter, a suction port is provided on the upper surface or the front surface of the outer frame, a plate-shaped filter arranged along the inner surface side of the suction port, a moving path for moving the filter, and a moving path for the moving path. The cleaning device includes a cleaning unit disposed on the way to clean the filter, and a transfer unit that moves the filter in the moving route. The moving route is formed along the inner surface side of the suction port and is arranged inside. It is formed by folding back in a U-shape in the space on the front side between the heat exchanger and the normal guide portion for holding the filter in the normal use position, and is connected to one end portion of the normal guide portion and is curved to the curved portion. A rotating brush that is in contact with each other and a dust box that stores dust scraped off by the brush are provided, and by moving the filter, the tip of the filter located at one end of the normal guide part is moved from the normal guide part. There is one that is folded back in a U shape at a curved portion and is automatically cleaned by the brush. (For example, see Patent Document 1)

また、清掃手段（清掃ブラシやダストボックス等）とフィルタ移送手段（フィルタ巻き取り装置等）を外枠内の上部後方でフィルタの先端部分に設けて、フィルタ先端を巻き取りながらブラシによって自動清掃を行うものがある。（例えば、特許文献２参照） Further, cleaning means (cleaning brush, dust box, etc.) and filter transfer means (filter winding device, etc.) are provided at the tip of the filter at the upper rear of the outer frame, and the brush is used for automatic cleaning while winding the tip of the filter. There is something. (For example, see Patent Document 2)

特許４１７５４０９号公報Japanese Patent No. 4175409 特開２００２−５５０４号公報JP, 2002-5504, A

これら従来例の空気調和機では、ダストボックスの容積が小さいためにフイルタ清掃で掻き取ったゴミを貯留する能力も小さいものであり、ダストボックスの容積を拡大するために、ダストボックスの設置スペースを大きく設ければ、空気調和機の全体寸法が大きくなり製造コストの上昇や、美観も損ねる懸念が有る。
また、ダストボックスが小さいとゴミ捨ての回数も多くなり、せっかくフイルタ清掃を自動にしても、これに替わってゴミ捨て作業が発生することで、使用者へのメリットが小さくなるだけでなく、使用者がゴミ捨て作業を行わずに放置し、ダストボックスがゴミでいっぱいになった場合には、溜まったゴミがフイルタ側に溢れたり、ブラシに絡まり故障が発生する危険が有る。 In these conventional air conditioners, since the dust box has a small volume, the ability to store dust scraped by the filter cleaning is also small, and in order to expand the dust box volume, a large dust box installation space should be provided. Therefore, there is a concern that the overall size of the air conditioner becomes large, the manufacturing cost rises, and the aesthetic appearance is impaired.
In addition, if the dust box is small, the number of times the dust is thrown increases, and even if the filter cleaning is done automatically, the dust throwing work will take place instead of this, which not only reduces the merit to the user but also If the dust box is left without performing the dust dumping work and the dust box is filled with dust, there is a risk that the collected dust may overflow to the filter side or the brush may become entangled and cause a failure.

上記課題を解決するために、特にその構成を、後板と前面カバーとオープンパネルとを備えた枠体を有し、前記枠体の上面に吸込口と、前記枠体の底面に吹出口と、前記吸込口と吹出口を連通し、前記吸込口から吸い込んだ室内空気を吹出口から送風する送風経路と、前記送風経路の吸込口内面側に沿って設けたフイルタと、前記フイルタと吹出口の間の送風経路に備えた熱交換器と、を有する空気調和機に於いて、前記後板の背面側に設けたフイルタ案内板と、前記後板の上部に設けたフイルタ掃除手段と、前記フイルタ案内板の後方に背面板と、を備え、前記後板とフィルタ案内板との間に第１空間を有し、前記フイルタ案内板と背面板の間に第２空間を有し、前記フイルタ掃除手段は、前記フィルタを第１空間へ送ってフイルタに付着したゴミを除去する構成とし、前記第２空間は、前記フィルタ掃除手段にて除去したゴミを下部に落下して集積するダストシュータで構成するようにしたものである。 In order to solve the above problems, in particular, the structure has a frame body including a rear plate, a front cover, and an open panel, a suction port on the upper surface of the frame body, and an outlet on the bottom surface of the frame body. An air blowing path for communicating the air inlet and the air outlet to blow indoor air sucked from the air inlet from the air outlet, a filter provided along an inner surface side of the air inlet of the air inlet, the filter and the air outlet An air conditioner having a heat exchanger provided in a ventilation path between the two, a filter guide plate provided on the back side of the rear plate, a filter cleaning means provided on the upper part of the rear plate, A rear plate is provided behind the filter guide plate, a first space is provided between the rear plate and the filter guide plate, and a second space is provided between the filter guide plate and the rear plate. Is configured to send the filter to the first space to remove dust adhering to the filter, and the second space is configured to be a dust shooter that collects dust removed by the filter cleaning means to the lower part and accumulates the dust. It was done like this.

この発明によれば、フイルタ案内板と背面板の間の空間にダストシュータを備え、ダストシュータ下部に取り除いたゴミを集積することで、大きなゴミ溜め空間を確保でき、空気調和機の全体寸法も比較的小さくでき、美観も向上できる。
また、大きなゴミ溜め空間を確保することで、ゴミ捨て作業の回数も少なくすることができ、ゴミが充満することが原因で発生するゴミの漏出や故障を防止できる。 According to this invention, a dust shooter is provided in the space between the filter guide plate and the back plate, and a large dust collecting space can be secured by accumulating the removed dust under the dust shooter, and the overall size of the air conditioner is relatively small. It can be made smaller and the aesthetics can be improved.
Further, by ensuring a large dust storage space, it is possible to reduce the number of times of dust disposal, and it is possible to prevent the dust from leaking out or malfunctioning due to the dust being filled.

室内機１の組立手順について説明する。まず、背面板２の左モータユニット取付部７６と右モータユニット取付部７８にモータユニット４０をそれぞれ組み込んでネジ止めする。次に、背面板２の固定用円柱８０にフィルタ案内板７９の固定孔８１で４か所ネジ止めして、背面板２の前方にフィルタ案内板７９を固定する。 The assembly procedure of the indoor unit 1 will be described. First, the motor unit 40 is assembled into the left motor unit mounting portion 76 and the right motor unit mounting portion 78 of the rear plate 2 and screwed. Next, the filter guide plate 79 is fixed to the front of the rear plate 2 by screwing the fixing column 80 of the rear plate 2 in four fixing holes 81 of the filter guide plate 79.

次に、フィルタ案内板７９の更に前方に後板３を取り付ける。背面板２に立設した取付リブ９６に後板３の取付孔９５を貫通して６か所ネジ止め固定することで後板３が背面板２に固定される。次に、ケーシング９０の前方で左側面９１と右側面９２の間に送風ファン１２が位置するように軸受けや送風モータ９３と共に固定する。次に、前部ドレンパン９９を送風ファン１２の前方に取り付けた後に、熱交換器１１を前部ドレンパン９９と後部ドレンパン８９を跨いで取り付ける。また、後板３底面のゴミ排出口１０１に下方からダストボックス１００を取り付ける。 Next, the rear plate 3 is attached further in front of the filter guide plate 79. The rear plate 3 is fixed to the rear plate 2 by passing through the mounting holes 95 of the rear plate 3 to the mounting ribs 96 provided upright on the rear plate 2 and fixing the rear plate 3 with screws at six positions. Next, in front of the casing 90, the blower fan 12 is fixed together with the bearing and the blower motor 93 so that the blower fan 12 is located between the left side surface 91 and the right side surface 92. Next, after attaching the front drain pan 99 to the front of the blower fan 12, the heat exchanger 11 is attached across the front drain pan 99 and the rear drain pan 89. Further, the dust box 100 is attached to the dust discharge port 101 on the bottom surface of the rear plate 3 from below.

次に、前面カバー４の後板３への取付を説明する。まず、後板３の左右上端に備えた前面カバー取付片９７の突起９８を、前面カバ−４の左右上端に備えた取付孔１２０に係止する。次に、取付孔１２０の係止状態で前面カバー４の全体を回動して前面カバー４を後板３に密着させ、前面カバー４の下部両端に一対備えた取付孔（図示せず）を貫通して後板３の前面カバー取付孔１０２にネジ止め固定する。 Next, attachment of the front cover 4 to the rear plate 3 will be described. First, the projections 98 of the front cover mounting pieces 97 provided on the left and right upper ends of the rear plate 3 are locked in the mounting holes 120 provided on the left and right upper ends of the front cover-4. Next, the front cover 4 is rotated as a whole in the locked state of the mounting hole 120 to bring the front cover 4 into close contact with the rear plate 3, and a pair of mounting holes (not shown) are provided at both lower ends of the front cover 4. It penetrates and is screwed and fixed to the front cover mounting hole 102 of the rear plate 3.

次に、ブラシユニット１５を前面カバー４の前方から左右に備えたスライド突起２４を前面カバー４の溝１１６に沿って後方へスライドさせ、溝１１６から連なる後板３の溝８８に案内し、ブラシユニット１５が最後部に突き当たった状態で下方に引き下ろすことで、ブラシユニット１５の係止突起２５が前面カバー４のコの字型係止部１１７に嵌り込み、ブラシユニット１５がセットされる。 Next, the slide protrusions 24 provided on the left and right sides of the front surface of the front cover 4 for the brush unit 15 are slid rearward along the grooves 116 of the front cover 4 and guided to the grooves 88 of the rear plate 3 which are continuous from the grooves 116. When the unit 15 hits the rearmost portion and is pulled down, the locking projection 25 of the brush unit 15 fits into the U-shaped locking portion 117 of the front cover 4, and the brush unit 15 is set.

次に、エアーフィルタ１０をフィルタ挿入部１１９から挿入する。フィルタ１０の先端はフイルタ溝１１８からユニット枠１８のスライド溝２７を経由してブラシ１９とフィルタ駆動部２０位置に突き当たってフィルタ１０のセットが完了する。この位置が室内機の通常運転時のフィルタ位置になる。次に、オープンパネル５を前面カバ−４の上フレーム１１２と前フレーム１１４に係止して取り付ければ室内機１の組立が完了する。 Next, the air filter 10 is inserted from the filter insertion portion 119. The tip of the filter 10 abuts the position of the brush 19 and the filter drive unit 20 from the filter groove 118 through the slide groove 27 of the unit frame 18, and the setting of the filter 10 is completed. This position is the filter position during normal operation of the indoor unit. Next, the open panel 5 is locked and attached to the upper frame 112 and the front frame 114 of the front cover 4 to complete the assembly of the indoor unit 1.

フィルタ１０の自動掃除運転の作動について説明する。室内機が空調運転を行うとフイルタ１０には室内に漂う空気中のゴミが吸込空気に混じって集積する、運転時間が長くなれば集積するゴミが多くなり熱交換器１１の熱交換効率が低下する前にフィルタ１０の掃除が必要になる。制御部４３で運転積算時間やその他掃除のタイミングを決定してフィルタ１０の自動掃除運転を開始する。ブラシモータ４１と送りモータ４２が回転を開始し、各モータの回転力がブラシ歯車２８と駆動歯車３０に伝わり、ブラシ１９とフィルタ駆動部２０か回転を開始する。フィルタ駆動部２０の回転によってフィルタ１０のラック１２７が噛み合い、フィルタ１０が後方のフィルタ経路８６（第１空間）側に徐々に引き込まれる。これと一緒にブラシ１９が回転してフィルタ１０の上面側に集積したゴミを取り除く。ブラシ１９に付着したゴミはフィルタ案内板７９のクシ歯８３でダストシュータ７２側に掻き落とされて、ダストシュータ７２内を落下しダストボックス１００に集積する。 The operation of the automatic cleaning operation of the filter 10 will be described. When the indoor unit performs an air conditioning operation, dust in the air floating in the room is mixed with the suction air and accumulates in the filter 10. When the operation time is long, the accumulated dust increases and the heat exchange efficiency of the heat exchanger 11 decreases. It is necessary to clean the filter 10 before doing so. The control unit 43 determines the cumulative operation time and other cleaning timing, and starts the automatic cleaning operation of the filter 10. The brush motor 41 and the feed motor 42 start rotating, the rotational force of each motor is transmitted to the brush gear 28 and the drive gear 30, and the brush 19 and the filter drive unit 20 start rotating. The rack 127 of the filter 10 meshes with the rotation of the filter driving unit 20, and the filter 10 is gradually drawn toward the rear filter path 86 (first space) side. Along with this, the brush 19 rotates to remove dust accumulated on the upper surface side of the filter 10. The dust attached to the brush 19 is scraped off by the comb teeth 83 of the filter guide plate 79 toward the dust shooter 72 side, falls inside the dust shooter 72, and accumulates in the dust box 100.

フィルタ１０の先端がフィルタ経路８６の下端に備えたフィルタセンサ１３２の位置に到達することで、送りモータ４２が逆回転に反転し、フィルタ１０は前面カバー４のフィルタ挿入部１１９側に戻っていく、この時ブラシモータ４１は正回転のまま回転を続けることでブラシ１９やクシ歯８３のゴミが逆戻りすることはない。このようなフィルタ１０の往復動作（掃除動作）を数回繰り返せば、フィルタ１０の掃除を確実にきれいにできる。そして、次回の自動掃除のタイミングが訪れるまで通常の空調運転を行うことを繰り返す。自動掃除運転の間隔は積算時間だけでなく、単純に時刻や曜日など色々に設定できる。また、操作部１２８やリモコン（図示せず）に手動掃除ボタンを設ければ、使用者だ手動で掃除運転を行うことができる。ダストボックス１００に溜まったゴミは後板３のゴミ排出口１０１からダストボックス１００を下方に取り外して行う。 When the tip of the filter 10 reaches the position of the filter sensor 132 provided at the lower end of the filter path 86, the feed motor 42 reverses to reverse rotation, and the filter 10 returns to the filter insertion portion 119 side of the front cover 4. At this time, since the brush motor 41 continues to rotate in the normal rotation, dust on the brush 19 and the comb teeth 83 does not return. By repeating such a reciprocating operation (cleaning operation) of the filter 10 several times, the filter 10 can be surely cleaned. Then, the normal air conditioning operation is repeated until the next automatic cleaning timing comes. The interval of automatic cleaning operation can be set not only for the total time, but simply for various times such as time of day and day of the week. If a manual cleaning button is provided on the operation unit 128 or a remote controller (not shown), the user can manually perform the cleaning operation. The dust collected in the dust box 100 is removed by removing the dust box 100 downward from the dust discharge port 101 of the rear plate 3.

このようにすることで、ゴミ捨て作業は数ヶ月または１年に１回等必要に応じて行われるが、ダストシュータ１００下部に取り除いたゴミを集積し、大きなゴミ溜め空間を確保でき、空気調和機の全体寸法も比較的小さくでき、美観も向上できる。また、大きなゴミ溜め空間を確保することで、ゴミ捨て作業の回数も少なくすることができ、ゴミが充満するすることが原因で発生するゴミの漏出や故障を防止できる。 By doing so, the dust disposal work is carried out as needed every few months or once a year, etc., but the removed dust can be collected under the dust shooter 100 to secure a large dust storage space, and air conditioning The overall size of the machine can be made relatively small and the aesthetics can be improved. Further, by ensuring a large dust collecting space, the number of times of dust disposal can be reduced, and it is possible to prevent dust from leaking out or malfunctioning due to the dust being filled.

また、フィルタ１０がブラシ１９とフイルタ駆動２０の間を通過する前後の変形角度も比較的小さいのでフィルタ１０を痛めることも少なくなり、これによってフィルタ１０が切れたり破れたりする故障も少なくすることができる。また、フィルタ案内板７９を背面板２と後板３の間に設けることで、フイルタ経路８６を確実に確保することで自動掃除運転時のフィルタ１０の移動を極めてスムーズに行うことができる。 In addition, since the deformation angle before and after the filter 10 passes between the brush 19 and the filter drive 20 is relatively small, the filter 10 is less likely to be damaged, and thus the failure of the filter 10 being cut or broken can be reduced. it can. Further, by providing the filter guide plate 79 between the rear plate 2 and the rear plate 3, it is possible to ensure the filter path 86, so that the filter 10 can be moved very smoothly during the automatic cleaning operation.
