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 it through a heat exchanger and returned to the room, but dust floating in the air is returned to the heat exchanger. An air filter is provided on the front side of the heat exchanger to prevent it from contaminating. When dust adheres to this filter to cause clogging and 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 provided with 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, it is necessary to move at least one of the filter and the cleaning brush in order to clean the entire surface of the filter with 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, and a plate-shaped filter arranged along the inner surface side of the suction port, a moving path for moving this filter, and a moving path of this moving path. It is provided with a cleaning means arranged in the middle for cleaning the filter and a transfer means for moving the filter in the moving path, and the moving path 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 front space between the heat exchanger, and is connected to a normal guide part that holds the filter in the normal use position and one end of this normal guide part, and also in a curved part. A rotating brush that comes into contact with each other and a dust box that stores dust scraped by this brush are provided, and by moving the filter, the tip of the filter, which is usually located at one end of the guide portion, is moved from the normal guide portion. There is a curved portion that is folded back in a U shape and automatically cleaned by the brush. (See, for example, 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) In addition, 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 automatic cleaning is performed with the brush while winding the filter tip. There is something. (See, for example, Patent Document 2)

First, the filter guide plate 74 is fixed to the front of the back plate 2 by screwing it to the fixing cylinder 75 of the back plate 2 at four places through the fixing holes 81 of the filter guide plate 79. Next, the rear plate 3 is attached further in front of the filter guide plate 74. The rear plate 3 is fixed to the back plate 2 by penetrating the mounting holes 96 of the rear plate 3 through the mounting ribs 97 erected on the back plate 2 and fixing them with screws at six places. Next, in the left motor unit mounting portion 70, the pedestal 67 in which the motor mounting plate 44 of the left motor unit 40L is formed on the back plate 2 and the rear plate 3, the first bead 68 and the second bead 69 of the front pedestal 98, Place the third bead 99 on the pedestal 67 and the front pedestal 98 with a guide.

Next, after the front drain pan 101 is attached to the front of the blower fan 12, the heat exchanger 11 is attached across the front drain pan 101 and the rear drain pan 90. Further, the dust box 102 is attached to the dust discharge port 103 on the bottom surface of the rear plate 3 from below.

次に、前面カバー4の背面板2、後板3への組み立て方について説明する。まず、背面板2の左右と中央に備えた前面カバー取付片87の突起88を、前面カバ−4の上フレーム112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104にネジ止め固定する。このとき、上押さえ部122(第3固定部)がモータユニット40の当接部58を上方からしっかり押圧することで、背面板2の台座67(第1固定部)や後板3の前台座98(第2固定部)との間に確実に固定される。また、モータユニット40は背面板2の第1ビード68と第2ビード69や、後板3の第3ビード99によってモータ取付板44の左右方向の位置ずれを防止する。 Next, how to assemble the front cover 4 to the back plate 2 and the rear plate 3 will be described. First, the protrusions 88 of the front cover mounting pieces 87 provided on the left, right, and center of the back plate 2 are locked to the mounting holes 120 provided in the upper frame 112 of the front cover-4. Next, in the locked state of the mounting holes 120, the entire front cover 4 is rotated so that the front cover 4 is brought into close contact with the rear plate 3, and a pair of mounting holes (not shown) provided at both lower ends of the front cover 4 are provided. It penetrates and is fixed to the front cover mounting hole 104 of the rear plate 3 by screwing. At this time, the upper pressing portion 122 (third fixed portion) firmly presses the contact portion 58 of the motor unit 40 from above, so that the pedestal 67 (first fixed portion) of the back plate 2 and the front pedestal of the rear plate 3 are pressed firmly. It is securely fixed to 98 (second fixing portion). Further, the motor unit 40 prevents the motor mounting plate 44 from being displaced in the left-right direction by the first bead 68 and the second bead 69 of the back plate 2 and the third bead 99 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、ブラシユニット15の係止突起25が前面カバー4の係止部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 cover 4 for the brush unit 15 are slid backward along the groove 116 of the front cover 4 to guide the brush unit 15, and the brush unit 15 is in contact with the rearmost portion. The locking projection 25 of the unit 15 is fitted into the 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の先端はフィルタ溝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の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 section 119. The tip of the filter 10 abuts from the filter groove 118 through the slide groove 27 of the unit frame 18 to the positions of the brush 19 and the filter drive unit 20, and the setting of the filter 10 is completed. This position is the filter position during normal operation of the indoor unit. Next, if the open panel 5 is locked and attached to the upper frame 112 and the front frame 114 of the front cover-4, the assembly of the indoor unit 1 is completed.

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1が空調運転を行うとフィルタ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74のクシ歯部83でダストシュータ63側に掻き落とされて、ダストシュータ63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 1 performs air-conditioning operation , dust in the air floating in the room is mixed with the suction air and accumulated in the filter 10. As the operation time becomes longer, the accumulated dust increases and the heat exchange efficiency of the heat exchanger 11 increases. It is necessary to clean the filter 10 before it drops. The control unit 43 determines the integrated operation time and other cleaning timings, and starts the automatic cleaning operation of the filter 10. The brush motor 41 and the feed motor 42 start to rotate, 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 to rotate. The rotation of the filter drive unit 20 causes the rack 127 of the filter 10 to engage, and the filter 10 is gradually pulled toward the rear filter path 86 (first space). Along with this, the brush 19 rotates to remove dust accumulated on the upper surface side of the filter 10. The dust adhering to the brush 19 is scraped off to the dust shooter 63 side by the comb tooth portion 83 of the filter guide plate 74, falls inside the dust shooter 63, 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やクシ歯部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102に溜まったゴミは後板3のゴミ排出口103からダストボックス102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 in reverse rotation, and the filter 10 returns to the filter insertion portion 119 side of the front cover 4. At this time, the brush motor 41 continues to rotate in the normal rotation, so that the dust on the brush 19 and the tooth portion 83 does not return. By repeating such a reciprocating operation (cleaning operation) of the filter 10 several times, the cleaning of the filter 10 can be surely cleaned. Then, the normal air-conditioning operation is repeated until the timing of the next automatic cleaning comes. The interval of the automatic cleaning operation can be set not only by the integrated time but also by simply setting the time and the day of the week. Further, if the operation unit 128 or the remote controller (not shown) is provided with a manual cleaning button, the user can manually perform the cleaning operation. The dust collected in the dust box 102 is collected by removing the dust box 102 downward from the dust discharge port 103 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63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。また、フィルタ10がブラシ19とフィルタ駆動部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74を背面板2と後板3の間に設けることで、フィルタ経路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。また、モータユニット40が所定の位置に適確に固定されているので、ブラシモータ41や送りモータ42の回転を、ブラシ19やフィルタ駆動部20にスムーズに伝達することができる。また、モータユニット40が所定の位置に適確に固定することで、フィルタ10の自動掃除運転における故障も少なくすることができる。 By doing so, the garbage disposal work is performed as needed, such as once every few months or a year, but the removed garbage can be accumulated in the lower part of the dust shooter 63, a large garbage storage space can be secured, and air conditioning can be achieved. The overall dimensions of the machine can be made relatively small, and the aesthetics can be improved. In addition, by securing a large garbage storage space, it is possible to reduce the number of times of garbage disposal work, and it is possible to prevent the leakage and failure of garbage caused by the filling of garbage. Further, since the deformation angle before and after the filter 10 passes between the brush 19 and the filter driving unit 20 is relatively small, the filter 10 is less likely to be damaged, and thus the failure of the filter 10 being cut or torn is also reduced. Can be done. Further, by providing the filter guide plate 74 between the back plate 2 and the rear plate 3, the filter path 86 can be reliably secured, so that the filter 10 can be moved extremely smoothly during the automatic cleaning operation. Further, since the motor unit 40 is appropriately fixed at a predetermined position, the rotation of the brush motor 41 and the feed motor 42 can be smoothly transmitted to the brush 19 and the filter drive unit 20. Further, by appropriately fixing the motor unit 40 at a predetermined position, it is possible to reduce failures in the automatic cleaning operation of the filter 10.
