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 having an air filter automatic cleaning function.

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、熱交換器の風上側にエアフィルタが設けられている。このエア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、エア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. In order to prevent contamination, an air filter is provided on the windward side of the heat exchanger. When dust adheres to the air filter and clogging occurs and the ventilation resistance increases, heat exchange is hindered, so that the air conditioning capability of the air conditioner decreases and power consumption increases. In order to eliminate such inconveniences, various air conditioners having an air filter automatic cleaning function have been proposed.

エアフィルタを自動的に清掃する場合、エアフィルタの全面を清掃ブラシで掃除するため、エア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。
エアフィルタを移動させる方式では、エアフィルタを移動させる移動経路を備え、この移動経路の途中に配されエアフィルタを移動させる移送手段とを備え、熱交換器の前方側空間に移動経路をU字状に折り返して形成し、更に、移動経路に接して回転ブラシと、このブラシで掻き取ったゴミを蓄えるダストボックス等のフィルタ清掃装置を熱交換器の前方側空間に備え、エアフィルタを移動させることによって、フィルタ清掃装置で自動清掃を行うものがある。(例えば、特許文献1参照)
When the air filter is automatically cleaned, it is necessary to move at least one of the air filter and the cleaning brush in order to clean the entire surface of the air filter with the cleaning brush.
In the method of moving the air filter, a moving path for moving the air filter is provided, and a transfer means is provided in the middle of the moving path to move the air filter, and the moving path is U-shaped in the front space of the heat exchanger. In addition, a rotary brush in contact with the moving path and a filter cleaning device such as a dust box for storing dust scraped off by this brush are provided in the space on the front side of the heat exchanger, and the air filter is moved. In some cases, automatic cleaning is performed by a filter cleaning device. (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)をフィルタ表面全体に移動させ自動清掃を行うものもある。
また、清掃手段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エア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, there is a type that performs automatic cleaning by moving a cleaning means (cleaning brush, dust box, etc.) over the entire filter surface.
Also, there is a type in which a cleaning means and a filter transfer means (filter take-up device or the like) are provided at the front end portion of the air filter behind the upper part in the outer frame, and automatic cleaning is performed with a brush while winding the filter front end. (For example, see Patent Document 2)

これら従来例の空気調和機では、フィルタ清掃装置の構造は複雑であり、多数の部品から構成され製造コストが上昇するため、製品価格も大幅に上昇する。
また、空気調和機の内部にフィルタ清掃装置を組み付ける大きな空間が必要であり、この組み付け空間があることで、空気調和機全体(特に奥行き寸法)が大きくなるものだった。
そこで、同じ外枠の空気調和機でフィルタ清掃装置を搭載せずに安価な機種を作成した場合には、外枠内のフィルタ清掃装置の取付け空間はそのままなので空気調和機全体は大きいままであり、初めからフィルタ清掃装置を搭載しない機種と比較すると大きいことにより材料費や輸送費等が上昇する問題があった。
In these conventional air conditioners, the structure of the filter cleaning device is complicated, and since it is composed of a large number of parts, the manufacturing cost increases, so the product price also increases significantly.
In addition, a large space for assembling the filter cleaning device inside the air conditioner is necessary, and the entire air conditioner (especially the depth dimension) becomes large due to this assembly space.
Therefore, when an inexpensive air conditioner with the same outer frame is installed without installing a filter cleaning device, the installation space for the filter cleaning device in the outer frame remains the same, so the entire air conditioner remains large. There is a problem that the material cost and the transportation cost increase due to the large size compared with the model not equipped with the filter cleaning device from the beginning.

A ventilation path that communicates the suction opening and the outlet, and blows indoor air sucked from the suction opening from the outlet; an air filter provided along the inner surface of the suction opening of the ventilation path; and the air filter In an air conditioner having a heat exchanger provided in the air flow path between the air outlets, and having an installation plate that is attached to the wall surface of the room and fixes the outer frame, on the back side of the rear plate, A filter cleaning set composed of a filter cleaning means and a back plate and the installation plate can be selected and attached.

この発明によれば、後板の背面側にフィルタ掃除手段と背面板とを積層して組み立て可能とし、フィルタ掃除セットと据付板を選択することで、フィルタ清掃装置を搭載した高級機種と、フィルタ清掃装置を搭載しない安価な機種で、同じ外枠の金型を使用することができ、かつ、部品の共通化や組立作業の共通化することでコストダウンをすることができる。
また、1種類の据付板で、フィルタ清掃装置を搭載した高級機種と、フィルタ清掃装置を搭載しない安価な機種の2種類の機種の据付をすることができる。
また、フィルタ掃除セットを選択したときには、ゴミの排出口にダストボックスを装着し、据付板を選択したときには、前記排出口を閉塞する排出口閉塞板を備え、前記排出口に排出口閉塞板を装着する構成とすることで、簡単に排出口を塞ぐことができ外観を損なうことを防止できる。
According to the present invention, the filter cleaning means and the back plate can be stacked and assembled on the back side of the rear plate, and the filter cleaning set and the installation plate are selected, so that a high-end model equipped with the filter cleaning device, the filter It is an inexpensive model that is not equipped with a cleaning device, can use a mold with the same outer frame, and can reduce costs by sharing parts and assembling work.
In addition, it is possible to install two types of models with one type of installation plate: a high-end model equipped with a filter cleaning device and an inexpensive model not equipped with a filter cleaning device.
In addition, when a filter cleaning set is selected, a dust box is attached to the dust outlet, and when an installation plate is selected, a dust outlet closing plate is provided to close the outlet, and a drain outlet closing plate is attached to the outlet. By adopting such a configuration, it is possible to easily close the discharge port and prevent the appearance from being impaired.

Next, the filter guide plate 79 is fixed to the front side of the back plate 2 by screwing the fixing plate 80 of the back plate 2 with 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 forward 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 through the mounting ribs 96 erected on the rear plate 2 and fixing them with six screws. Next, the blower fan 12 is fixed together with the bearing and the blower motor 93 so that the blower fan 12 is positioned between the left side surface 91 and the right side surface 92 in front of the casing 90. 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 protrusions 98 of the front cover mounting piece 97 provided at the left and right upper ends of the rear plate 3 are engaged with the mounting holes 120 provided at the left and right upper ends of the front cover-4. Next, the entire front cover 4 is rotated while the mounting hole 120 is locked to bring the front cover 4 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. It penetrates and is fixed to the front cover mounting hole 102 of the rear plate 3 with screws.

By pulling downward while the unit 15 is in contact with the rearmost portion, the locking protrusion 25 of the brush unit 15 is fitted into the U-shaped locking portion 117 of the front cover 4 and the brush unit 15 is set.

次に、エアフィルタ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 against the position of the brush 19 and the filter driving unit 20 from the filter groove 118 via 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, assembling of the indoor unit 1 is completed when the open panel 5 is locked and attached to the upper frame 112 and the front frame 114 of the front cover 4.

室内の壁面への取付について説明すれば、まず、前記据付板57が取り付けられる位置や壁面の状態、材質等に応じて長孔61やネジ穴62を適宜選択して据付板57を壁面にネジ止めする。次に、据付板57上部の舌片58に、背面板2の係止凹部70を挿入して係止することで、背面板2の上部を据付板57に係止する。そして、据付板57の下部の係止片59に備えた係止孔60に、背面板2の爪部71を係止することで背面板2の下部を据付板57に固定する。   The installation to the wall surface in the room will be described. First, the long hole 61 and the screw hole 62 are appropriately selected according to the position where the installation plate 57 is attached, the state of the wall surface, the material, etc., and the installation plate 57 is screwed to the wall surface. Stop. Next, the upper portion of the back plate 2 is locked to the installation plate 57 by inserting and locking the locking recess 70 of the back plate 2 to the tongue piece 58 on the top of the installation plate 57. Then, the lower portion of the rear plate 2 is fixed to the installation plate 57 by engaging the claw portion 71 of the rear plate 2 in the engagement hole 60 provided in the engagement piece 59 at the lower portion of the installation plate 57.

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 air-conditioning operation, the dust in the air drifting in the room is mixed with the intake air and accumulates in the filter 10, and the accumulated dust increases as the operation time increases, and the heat exchange efficiency of the heat exchanger 11 decreases. Before cleaning, the filter 10 needs to be cleaned. The control unit 43 determines the accumulated 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 is engaged with the rotation of the filter driving unit 20, and the filter 10 is gradually pulled toward the rear filter path 86 (first space). At the same time, 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 72 side by the comb teeth 83 of the filter guide plate 79, 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 is reversed in the reverse direction, and the filter 10 returns to the filter insertion portion 119 side of the front cover 4. At this time, the brush motor 41 keeps rotating in the forward direction, so that the dust on the brush 19 and the comb teeth 83 does not return. If such a reciprocating operation (cleaning operation) of the filter 10 is repeated several times, the cleaning of the filter 10 can be surely cleaned. Then, the normal air-conditioning operation is repeated until the next automatic cleaning timing comes. The automatic cleaning operation interval can be set not only for the accumulated time but also for various times such as time and day of the week. Further, 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 garbage disposal work is performed once a few months or once a year, if necessary. However, the removed garbage is accumulated at the bottom of the dust shooter 100 to ensure a large garbage storage space and air conditioning. 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 garbage disposal operations, and it is possible to prevent the leakage and breakdown of garbage caused by the filling of garbage.

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。   Further, since the deformation angle before and after the filter 10 passes between the brush 19 and the filter drive 20 is also relatively small, the filter 10 is less likely to be damaged, thereby reducing the failure of the filter 10 to be cut or torn. it can. Further, by providing the filter guide plate 79 between the back plate 2 and the rear plate 3, it is possible to move the filter 10 very smoothly during the automatic cleaning operation by ensuring the filter path 86 with certainty.

次に、フィルタ掃除セット(フィルタ清掃機能)を搭載せずに安価な機種を作成した場合の構成を、図14〜16と図20〜23を基に説明する。   Next, a configuration when an inexpensive model is created without mounting a filter cleaning set (filter cleaning function) will be described based on FIGS. 14 to 16 and FIGS.

The upper surface rib 143 is brought into contact with the lower part of the upper rail 149 of the rear plate 3. Next, a screw hole 145 is passed through from the back side and screwed to a vertical beam 150 formed in the rear opening 140 of the rear plate 3, and a plurality of screws are passed through a mounting hole 95 provided in the rear plate 3 to a screw boss 147. It is fixed.

次に、ダストボックス100を取り除くと、後板3底面にゴミ排出口101が表れる。このゴミ排出口101が開口しても室内機の性能上は問題無いが、意匠の低下を防止するために排出口閉塞板151が必要になる。この排出口閉塞板151はゴミ排出口101よりもやや大きく横長方形状の板の左右辺部に、ゴミ排出口101の左右縁に下方から係止する蓋突起152とバネ部153を有している。また、背面板2が取り除かれることで、据付板57下部の係止孔60に係止していた背面板2の爪部71が無くなることを補うために、排出口閉塞板151の内側で据付板57の係止孔60に対向する位置に、背面板2の爪部71と略同形状の蓋爪部154を形成し後板3の下方を固定する構造とする。   Next, when the dust box 100 is removed, the dust discharge port 101 appears on the bottom surface of the rear plate 3. Even if the dust discharge port 101 is opened, there is no problem in the performance of the indoor unit, but the discharge port closing plate 151 is necessary to prevent the design from being deteriorated. This discharge port closing plate 151 has lid protrusions 152 and spring portions 153 that are engaged with the left and right edges of the dust discharge port 101 from below on the left and right sides of a horizontally rectangular plate that is slightly larger than the dust discharge port 101. Yes. Further, in order to compensate for the fact that the claw portion 71 of the back plate 2 that has been locked in the lock hole 60 at the bottom of the installation plate 57 is eliminated by removing the back plate 2, the back plate 2 is installed inside the discharge port closing plate 151. A lid claw portion 154 having substantially the same shape as the claw portion 71 of the back plate 2 is formed at a position facing the locking hole 60 of the plate 57, and the lower portion of the rear plate 3 is fixed.

前記排出口閉塞板151のゴミ排出口101への取り付けについて説明すれば、まず、やや突出する蓋爪部154をゴミ排出口101の内側へ入れてからゴミ排出口101の左右縁に蓋突起152とバネ部153を嵌め込んでセットする。また、排出口閉塞板151を取り付けた状態で据付板57下部の係止孔60に蓋爪部154を係止することで後板3(室内機1)を据付板57に固定することができる。尚、この実施例では蓋突起152とバネ部153による構成にしたが、排出口閉塞板151のゴミ排出口101への取り付け構造については、ネジ止めにして強度を向上した構成にしても良い。   The attachment of the discharge port closing plate 151 to the dust discharge port 101 will be described. First, a slightly protruding lid claw portion 154 is placed inside the dust discharge port 101 and then the lid protrusions 152 on the left and right edges of the dust discharge port 101. And the spring part 153 is fitted and set. Further, the rear plate 3 (indoor unit 1) can be fixed to the installation plate 57 by engaging the lid claw portion 154 in the engagement hole 60 below the installation plate 57 with the discharge port closing plate 151 attached. . In this embodiment, the cover projection 152 and the spring portion 153 are used. However, the attachment structure of the discharge port closing plate 151 to the dust discharge port 101 may be screwed to improve the strength.

次に、フィルタ掃除セットを搭載せずに安価な機種を作成した場合に於ける室内機1の組立手順について説明する。まず、後板3の後部開口部140に背面側から上部閉塞板141を多数のネジでネジ止めする。次に、後板3のゴミ排出口101に排出口閉塞板151を嵌め込んでセットする。   Next, an assembly procedure of the indoor unit 1 when an inexpensive model is created without mounting the filter cleaning set will be described. First, the upper closing plate 141 is screwed to the rear opening 140 of the rear plate 3 from the back side with a number of screws. Next, the discharge port closing plate 151 is fitted into the dust discharge port 101 of the rear plate 3 and set.

次に、送風ファン12や送風モータ93、前部ドレンパン99、熱交換器11、前面カバー4、エアフィルタ10、オープンパネル5の組立は先に説明した、フィルタ掃除セットを搭載した機種とほぼ同じ工程で組み立てることができる。   Next, the assembly of the blower fan 12, the blower motor 93, the front drain pan 99, the heat exchanger 11, the front cover 4, the air filter 10, and the open panel 5 is almost the same as the model equipped with the filter cleaning set described above. Can be assembled in the process.

室内の壁面への取付について説明すれば、まず、据付板57を壁面にネジ止めする。次に、据付板57上部の舌片58に、上部閉塞板141の係止凹部144を挿入して係止することで、後板3の上部を据付板57に係止する。そして、据付板57の下部の係止片59に備えた係止孔60に、排出口閉塞板151の蓋爪部154を係止することで後板3の下部を据付板57に固定することができる。   If the attachment to a wall surface in a room is explained, first, the installation plate 57 is screwed to the wall surface. Next, the upper portion of the rear plate 3 is locked to the installation plate 57 by inserting and locking the locking recess 144 of the upper closing plate 141 into the tongue piece 58 on the upper side of the installation plate 57. Then, the lower portion of the rear plate 3 is fixed to the installation plate 57 by engaging the lid claw portion 154 of the discharge port closing plate 151 in the engagement hole 60 provided in the engagement piece 59 at the lower portion of the installation plate 57. Can do.

このようにすることで、後板3の背面側にフィルタ掃除手段と背面板2とを積層して組み立て可能とし、フィルタ掃除セットと据付板57を選択することで、フィルタ清掃装置を搭載した高級機種と、フィルタ清掃装置を搭載しない安価な機種で、同じ外枠の金型を使用することができ、かつ、部品の共通化や組立作業の共通化することでコストダウンをすることができる。   In this way, the filter cleaning means and the back plate 2 can be stacked and assembled on the back side of the rear plate 3, and the filter cleaning set and the installation plate 57 can be selected to install a high-quality filter cleaning device. The model and an inexpensive model that does not have a filter cleaning device can be used, and the same outer frame mold can be used, and the cost can be reduced by using common parts and assembly work.

また、1種類の据付板57で、フィルタ清掃装置を搭載した高級機種と、フィルタ清掃装置を搭載しない安価な機種の2種類の機種の据付をすることができる。
また、フィルタ掃除セットを選択したときには、ゴミの排出口101にダストボックス100を装着し、据付板57を選択したときには、排出口101を閉塞する排出口閉塞板141を備え、排出口101に排出口閉塞板151を装着する構成とすることで、簡単に排出口101を塞ぐことができ外観を損なうことを防止できる。
また、排出口閉塞板151に蓋爪部154を備えることで、より簡単に部品の共通化や組立作業の共通化とコストダウンをすることができる。
In addition, one type of installation plate 57 can be used to install two types of models: a high-end model equipped with a filter cleaning device and an inexpensive model not equipped with a filter cleaning device.
Further, when the filter cleaning set is selected, the dust box 100 is attached to the dust discharge port 101, and when the installation plate 57 is selected, a discharge port closing plate 141 for closing the discharge port 101 is provided, and the discharge port 101 has a discharge port. By adopting a configuration in which the blocking plate 151 is mounted, it is possible to easily block the discharge port 101 and prevent the appearance from being impaired.
In addition, by providing the lid claw portion 154 in the discharge port closing plate 151, it is possible to more easily share parts, share assembling work, and reduce costs.
