Description

本発明は、室内ユニットの空気吸込口に設けられたエアフィルタを自動的に清掃する機能を備えた空気調和機に関する。   The present invention relates to an air conditioner having a function of automatically cleaning an air filter provided in an air suction port of an indoor unit.

従来の空気調和機のフィルタ装置は、室内ユニットの本体内部への塵埃の侵入を防止す
るためのエアフィルタが熱交換器の前面に設けられており、このエアフィルタは付着した塵埃を手で清掃できるように着脱自在に構成されている。こうした構成のフィルタ装置は頻繁なメンテナンスが必要となるだけでなく、メンテナンスが行われるまでの間にはエアフィルタが徐々に目詰まりしていき、その結果、熱交換器を通過する風量が低下し、空調能力が低下して消費電力の増大につながることとなる。 In the conventional air conditioner filter device, an air filter is installed on the front of the heat exchanger to prevent dust from entering the inside of the indoor unit body. It is configured to be detachable so that it can. The filter device having such a configuration not only requires frequent maintenance, but also gradually clogs the air filter until the maintenance is performed, and as a result, the amount of air passing through the heat exchanger decreases. As a result, the air conditioning capacity is reduced, leading to an increase in power consumption.

このため、エアフィルタのメンテナンスの手間を低減する目的で、エアフィルタに付着した塵埃をブラシにより定期的に清掃する自動清掃装置が提案されている（例えば、特許文献１参照。）。   For this reason, an automatic cleaning device that periodically cleans dust adhering to the air filter with a brush has been proposed for the purpose of reducing maintenance work of the air filter (see, for example, Patent Document 1).

特開２００１−９９４７９号公報JP 2001-99479 A

しかしながら、特許文献１に記載の自動清掃装置の場合、ブラシとエアフィルタがお互いにこすられるためブラシに塵埃が絡みついたり、ブラシが摩耗もしくは変形して機能低下するなどの問題があった。また、ある程度の時間が経過するとブラシで掻き落として集めた塵埃を処理しなくてはならずメンテナンスの手間が大幅に軽減されるものではなかった。   However, in the case of the automatic cleaning device described in Patent Document 1, there are problems that the brush and the air filter are rubbed against each other, so that dust is entangled with the brush, and the brush is worn or deformed to deteriorate its function. In addition, after a certain amount of time has passed, the dust collected by scraping with a brush must be treated, and the labor of maintenance has not been greatly reduced.

本発明は、従来技術の有するこのような問題点に鑑みてなされたものであり、エアフィルタ全面を自動的に吸引清掃することでメンテナンスを軽減するとともに、室内ユニット本体を小型に設定しても本来の基本性能を損なわない空気調和機を提供することを目的としている。   The present invention has been made in view of the above-described problems of the prior art, and reduces the maintenance by automatically sucking and cleaning the entire surface of the air filter and reducing the size of the indoor unit main body. The object is to provide an air conditioner that does not impair the original basic performance.

上記目的を達成するため、本発明は、熱交換器で熱交換された空気を室内に吹き出す室内ユニットを有する空気調和機であって、前記熱交換器を通過する空気の塵埃を除去するエアフィルタと、該エアフィルタから塵埃を掻き落す塵埃分離部材と、該塵埃分離部材で掻き落した塵埃を吸引する吸引装置とを備え、前記エアフィルタのエアフィルタ枠には塵埃分離部材を収納する収納部を設け、該収納部の面を前記エアフィルタの延長面より風下側に配設して、前記塵埃分離部材が前記収納部に収納された状態では、前記塵埃分離部材の先端と前記収納部の面とを離し、前記塵埃除去部材が前記収納部の風上側の面に当接しない構成としたことを特徴とする。 In order to achieve the above object, the present invention provides an air conditioner having an indoor unit that blows out the air heat-exchanged by a heat exchanger into the room, and removes air dust passing through the heat exchanger. And a dust separating member for scraping dust from the air filter, and a suction device for sucking the dust scraped off by the dust separating member, and a storage portion for storing the dust separating member in the air filter frame of the air filter In the state where the surface of the storage portion is disposed on the leeward side of the extended surface of the air filter, and the dust separation member is stored in the storage portion, the tip of the dust separation member and the storage portion The dust removing member is separated from the surface, and the dust removing member is not in contact with the windward surface of the storage unit .

また、本発明は前記収納部に前記塵埃分離材を位置決めする位置決め手段を設けたことを特徴とする。   Further, the present invention is characterized in that positioning means for positioning the dust separating material is provided in the storage portion.

また、本発明の前記収納部は、前記エアフィルタと、前記室内ユニットの端部に位置する電源箱との間に設けられると共に、冷凍サイクル配管の前方に設けられたことを特徴とする。   The storage unit of the present invention is provided between the air filter and a power supply box located at an end of the indoor unit, and is provided in front of a refrigeration cycle pipe.

この構成をなすことにより、本発明はエアフィルタの塵埃を自動的に清掃することができる。   With this configuration, the present invention can automatically clean the dust of the air filter.

以下、本発明の実施の形態について、図面を参照しながら説明する。
図１乃至図５は、本発明にかかる空気調和機のフィルタ装置を示しており、図１および図２において、熱交換器を通過する空気の塵埃を除去するエアフィルタ２は、フィルタ枠１に支持固定され、エアフィルタ２の表面に沿って移動可能な吸引ノズル３が設けられる。吸引ノズル３はフィルタ枠１の上下端に設置された一対のガイドレール４により、エアフィルタ２と極めて狭い間隙を保って円滑に左右に移動することができる。吸引ノズル３の左右方向への駆動手段は図示しないが、モーターによる駆動力を歯車等の伝達手段で構成するものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show a filter device of an air conditioner according to the present invention. In FIGS. 1 and 2, an air filter 2 that removes dust of air passing through a heat exchanger is provided in a filter frame 1. A suction nozzle 3 that is supported and fixed and movable along the surface of the air filter 2 is provided. The suction nozzle 3 can move smoothly to the left and right with a very narrow gap from the air filter 2 by a pair of guide rails 4 installed at the upper and lower ends of the filter frame 1. Although the drive means for the suction nozzle 3 in the left-right direction is not shown, the drive force by the motor is constituted by a transmission means such as a gear.

吸引ノズル３には吸引ダクト５の一端が連結され、吸引ダクト５の他端は吸引装置６に連結される。吸引ダクト５は吸引ノズル３の移動に差し支えないように折り曲げ可能なダクトで形成される。また、吸引装置６には排気ダクト７が連結され、室外へ引き回される。エアフィルタ２に付着した塵埃は吸引ノズル３により吸引された後、吸引ダクト５、吸引装置６、排気ダクト７を経由して室外へ排出される。   One end of a suction duct 5 is connected to the suction nozzle 3, and the other end of the suction duct 5 is connected to a suction device 6. The suction duct 5 is formed of a duct that can be bent so as not to interfere with the movement of the suction nozzle 3. Further, an exhaust duct 7 is connected to the suction device 6 and is routed outside the room. Dust adhering to the air filter 2 is sucked by the suction nozzle 3 and then discharged to the outside through the suction duct 5, the suction device 6 and the exhaust duct 7.

なお、エアフィルタ２は、図５に示すようにフィルタ桟２ａとネット２ｂと横桟２ｃとから構成されている。   In addition, the air filter 2 is comprised from the filter crosspiece 2a, the net | network 2b, and the horizontal crosspiece 2c, as shown in FIG.

また、吸引ノズル３は図３及び図４に示すように、吸引した風の流通路を構成するノズル８と、ノズル８を囲むように摺動自在に取り付けられたフィルム９と、フィルム９を支持して駆動力を伝えるギヤ１４と、フィルム９を支持して円滑に駆動させるためのローラー１５ａ、１５ｂ、１５ｃから構成される。ノズル８のエアフィルタ２側の面には、エアフィルタ２の縦長さに相当する長さでスリット状のノズル開口部１０が設けてある。一方、フィルム９はループ状に形成され、ノズル開口部１０を覆うようにノズル８の外周に巻き付けられ、エアフィルタ２側の面は、ノズル開口部１０に対向する開口部１６が形成されたフィルムガイド１７で支持されている。フィルム９にはスリット状の吸引孔１１が設けてあり、吸引孔１１がノズル開口部１０とエアフィルタ２に対向するようにフィルム９は取り付けられている。フィルム９の両側には多数の駆動穴が等間隔に形成されており、ステッピングモーターに連結されたギヤ１４が、駆動穴に噛み合うことによりフィルム９は上下方向のいずれにも自在に摺動できるようになっている。   As shown in FIGS. 3 and 4, the suction nozzle 3 supports a nozzle 8 constituting a flow path of sucked air, a film 9 slidably attached so as to surround the nozzle 8, and the film 9. The gear 14 transmits the driving force and the rollers 15a, 15b, 15c for supporting the film 9 and driving it smoothly. A slit-like nozzle opening 10 having a length corresponding to the longitudinal length of the air filter 2 is provided on the surface of the nozzle 8 on the air filter 2 side. On the other hand, the film 9 is formed in a loop shape, wound around the outer periphery of the nozzle 8 so as to cover the nozzle opening 10, and the air filter 2 side surface is formed with an opening 16 facing the nozzle opening 10. Supported by a guide 17. The film 9 is provided with a slit-like suction hole 11, and the film 9 is attached so that the suction hole 11 faces the nozzle opening 10 and the air filter 2. A large number of drive holes are formed on both sides of the film 9 at equal intervals, and the gear 14 connected to the stepping motor meshes with the drive holes so that the film 9 can slide freely in any of the vertical directions. It has become.

以上のような構成により、吸引装置６によって吸引される風量は吸引孔１１に絞られて集中することとなるので、少ない風量でも吸引孔１１部分では強い風速を発生させることが可能となり、小出力で強い吸引力を発揮できる。この強い吸引力で吸引されたエアフィルタ上の塵埃は、吸引孔１１からノズル開口部１０を経てノズル８内部に入り、さらに吸引ダクト５、吸引装置６、排気ダクト７を経由して室外へ排出される。そして、吸引ノズ
ル３を左右に駆動する毎に、フィルム９に設けた吸引孔１１の位置を上下方向に変更することで、エアフィルタ２全面を吸引清掃することが可能となる。 With the configuration as described above, the air volume sucked by the suction device 6 is concentrated in the suction hole 11, so that even with a small air volume, it is possible to generate a strong wind speed in the suction hole 11 portion, and a small output Can exert strong suction power. Dust on the air filter sucked by this strong suction force enters the nozzle 8 from the suction hole 11 through the nozzle opening 10, and further discharges outside through the suction duct 5, the suction device 6 and the exhaust duct 7. Is done. And every time the suction nozzle 3 is driven left and right, the entire surface of the air filter 2 can be suction-cleaned by changing the position of the suction hole 11 provided in the film 9 in the vertical direction.

本発明においては、吸引清掃が終了した後、空気調和機の基本性能を損なわない位置に吸引ノズル３を収納するように設定している。すなわち、図１に示すように、吸引ノズル３がエアフィルタ２を吸引清掃後に、吸引ノズル３をエアフィルタ２と重ならない位置（対向しない位置）に収納することにより、空気調和機の基本性能を十分に発揮することができる。換言すれば、空気調和機の運転時に吸引ノズル３をエアフィルタ２と重ならない位置に収納して、吸引ノズル３を空気調和機の運転時の障害にならないように設定することで、空気調和機の本来の基本性能を確保することができる。   In the present invention, after the suction cleaning is completed, the suction nozzle 3 is set to be stored in a position that does not impair the basic performance of the air conditioner. That is, as shown in FIG. 1, after the suction nozzle 3 sucks and cleans the air filter 2, the suction nozzle 3 is housed in a position that does not overlap the air filter 2 (a position that does not face the air filter 2). Can fully demonstrate. In other words, by storing the suction nozzle 3 in a position that does not overlap the air filter 2 during operation of the air conditioner, and setting the suction nozzle 3 so as not to become an obstacle during operation of the air conditioner, the air conditioner The original basic performance can be secured.

以下、ノズル収納スペースの具体例について説明する。   Hereinafter, a specific example of the nozzle storage space will be described.

図１及び図２は、吸引ノズル３の収納部１ａをエアフィルタ枠１の一部（図１及び図２では、フィルタ枠１の右端）に設け、空気調和機の運転中はこの収納部１ａに吸引ノズル３を収納している。この構成は、図１に示すフィルタ装置完成品として室内ユニット本体に容易に組み込むことができ、組立工数の低減を図ることが可能となる。   1 and 2 show that the storage portion 1a of the suction nozzle 3 is provided in a part of the air filter frame 1 (the right end of the filter frame 1 in FIGS. 1 and 2), and this storage portion 1a is operated during operation of the air conditioner. The suction nozzle 3 is housed in the container. This configuration can be easily incorporated into the indoor unit main body as a completed filter device shown in FIG. 1, and the number of assembly steps can be reduced.

図６に示すように、吸引ノズル３の収納部１ａには、吸引ノズル３の位置決め手段１８が設けられており、空気調和機の運転中における吸引ノズル３の収納位置を所定の位置に設定することで、安定したノズル収納が可能になる。位置決め手段１８は、例えば接触式の位置センサーで構成され、エアフィルタ２の清掃後、吸引ノズル３が図６に示す収納部１ａに移動して位置決め手段１８に接触すると、位置決め手段１８はオン信号を制御装置（図示せず）に出力し、制御装置は吸引ノズル３をその位置に停止させる。   As shown in FIG. 6, the storage unit 1a of the suction nozzle 3 is provided with positioning means 18 for the suction nozzle 3, and sets the storage position of the suction nozzle 3 to a predetermined position during operation of the air conditioner. Thus, stable nozzle storage becomes possible. The positioning means 18 is composed of, for example, a contact-type position sensor. After the air filter 2 is cleaned, when the suction nozzle 3 moves to the storage portion 1a shown in FIG. Is output to a control device (not shown), and the control device stops the suction nozzle 3 at that position.

また、図６に示す例では、吸引ノズル３の収納部１ａは、エアフィルタ２と、室内ユニット本体２１の端部に位置する電源箱２０との間に設けられるとともに、図７に示すように、冷凍サイクル配管１９の前方に設けられており、この構成は、製品スペースの有効活用ができ、室内ユニット本体２１の小型化を図ることができる。   In the example shown in FIG. 6, the storage portion 1a of the suction nozzle 3 is provided between the air filter 2 and the power supply box 20 located at the end of the indoor unit main body 21, and as shown in FIG. The structure is provided in front of the refrigeration cycle pipe 19, and this configuration can effectively use the product space and can reduce the size of the indoor unit main body 21.

なお、上記実施の形態において、吸引ノズル３に形成された吸引孔１１にエアフィルタ２に付着した塵埃を吸引するようにしたが、吸引孔１１に沿ってブラシ等の塵埃分離部材を取り付け、エアフィルタ２の清掃時、塵埃分離部材により塵埃をエアフィルタ２から掻き落としながら吸引孔１１に塵埃を吸引するようにしてもよい。この場合、吸引ノズル３に対向する収納部１ａの面をエアフィルタ２の延長面より後方に設定し、吸引ノズル３が収納部１ａに収納されている状態では、塵埃分離部材が収納部１ａの前記面と当接しないように構成するのが好ましい。   In the above embodiment, dust attached to the air filter 2 is sucked into the suction hole 11 formed in the suction nozzle 3. A dust separation member such as a brush is attached along the suction hole 11 to When cleaning the filter 2, the dust may be sucked into the suction hole 11 while the dust separating member scrapes off the dust from the air filter 2. In this case, when the surface of the storage portion 1a facing the suction nozzle 3 is set behind the extended surface of the air filter 2, and the suction nozzle 3 is stored in the storage portion 1a, the dust separating member is the storage portion 1a. It is preferable to configure so as not to contact the surface.

本発明の空気調和機のフィルタ装置は、エアフィルタに付着した塵埃の自動的な吸塵排出が可能になり、基本性能の維持も可能となるので、他のフィルタ使用商品の用途にも適用できる。   The filter device for an air conditioner according to the present invention can automatically absorb and discharge dust adhering to the air filter, and can maintain the basic performance, so that it can be applied to other products using filters.
