Description

本発明は、エアコンディショナーや送風機、加湿器、除湿機、換気扇、あるいは空気清浄機等の空気調和機に配置されたエアフィルターの清掃体、回転ロータ、及び、それを用いた空気調和機に関するものである。 The present invention relates to an air filter cleaning body, a rotary rotor, and an air conditioner using the same arranged in an air conditioner such as an air conditioner, a blower, a humidifier, a dehumidifier, a ventilation fan, or an air purifier. It is.

従来の空気調和機には、吸込口と熱交換器との間に、空気調和機本体内部への塵埃侵入を防ぐためにエアフィルターが配置されており、空気調和機の運転に伴い吸込口から空気と共に侵入する塵埃を捉える機能を有している。このため、エアフィルターには捉えた塵埃が徐々に付着し、また、油分を含む塵埃はこびりついて、目が徐々に詰まってしまい風量を低下させてしまうので、空気調和機本体から着脱可能に構成され、定期的にエアフィルター表面を電気掃除機等で吸引したり、洗浄したりしなければならなかった。 In a conventional air conditioner, an air filter is disposed between the suction port and the heat exchanger to prevent dust from entering the air conditioner body, and air flows from the suction port as the air conditioner operates. And has a function of catching intruding dust. For this reason, the dust caught on the air filter gradually adheres, and the dust containing oil is stuck and the eyes are gradually clogged to reduce the air volume, so it can be detached from the air conditioner body. Therefore, the air filter surface had to be regularly sucked or cleaned with an electric vacuum cleaner or the like.

これに対し、エアフィルターの上流側表面に沿って移動することができる吸引口を有する吸引ノズルと、この吸引ノズルに連結された吸引装置を空気調和機本体に設けて、吸引口からエアフィルター表面に付着した塵埃を吸引することで、エアフィルターを取り外すことなくエアフィルターの自動清掃が行える構造が考案されている（例えば、特許文献１参照）。 On the other hand, a suction nozzle having a suction port that can move along the upstream surface of the air filter, and a suction device connected to the suction nozzle are provided in the air conditioner body, and the air filter surface extends from the suction port. A structure has been devised that can automatically clean the air filter without removing the air filter by sucking the dust adhering to the surface (see, for example, Patent Document 1).

また、回転ロータを空気調和機本体に設けて、エアフィルター表面に付着した塵埃を掻き取ることで、エアフィルターを取り外すことなくエアフィルターの自動清掃が行える構造が考案されている。図１１は回転ロータ４８を設けた、空気調和機本体の要部断面図である。１は空気調和機本体、２は空気調和機本体１の前面から上面にかけて形成された吸込口、３は空気調和機本体１の下部に形成された吹出口である。吸込口２と吹出口３を結ぶ空気通路には空気中の塵埃を取り除くエアフィルター５と送風ファン６、熱交換器４が配置されている。エアフィルター５の塵埃を除去する手段として、回転ロータ４８が具備されている。また、回転ロータ４８は、図１２のように、棒状のロータ５４の溝部に、可撓性を有するエラストマー等で作られた、帯状の先端部の長手方向に連続的なリブ部５０を設けた軟質ブレード４９を有して構成されている。塵埃の除去運転の開始に当たり、回転ロータ４８は、エアフィルター５の下端に位置している。塵埃の除去運転を開始すると、回転駆動手段（図示せず）により回転ロータ４８が矢印の方向に回転すると共に、その回転する回転ロータ４８が上下移動手段（図示せず）で、エアフィルター５の表面に沿って上方に移動する。この間に、回転ロータ４８で、エアフィルター５に付着しこびりついた油分を含む塵埃等が掻き落とされる。次に、上下移動手段（図示せず）により、回転ロータ４８が、エアフィルター５の上端まで達すると、自動的に下降し、エアフィルター５の下端まで移動する。この間も上昇時と同様に、回転ロータ４８で、エアフィルター５に付着しこびりついた油分を含む塵埃等が掻き落とされる装置が考案されている。 In addition, a structure has been devised in which a rotary rotor is provided in an air conditioner body and dust is adhered to the surface of the air filter so that the air filter can be automatically cleaned without removing the air filter. FIG. 11 is a cross-sectional view of the main part of the air conditioner main body provided with the rotating rotor 48. Reference numeral 1 denotes an air conditioner body, 2 denotes a suction port formed from the front surface to the upper surface of the air conditioner body 1, and 3 denotes an air outlet formed at a lower portion of the air conditioner body 1. An air filter 5 that removes dust in the air, a blower fan 6, and a heat exchanger 4 are disposed in an air passage that connects the suction port 2 and the blower outlet 3. A rotating rotor 48 is provided as means for removing dust from the air filter 5. Further, as shown in FIG. 12, the rotary rotor 48 is provided with a continuous rib portion 50 in the longitudinal direction of the belt-shaped tip portion made of a flexible elastomer or the like in the groove portion of the rod-shaped rotor 54. A soft blade 49 is provided. At the start of the dust removal operation, the rotary rotor 48 is positioned at the lower end of the air filter 5. When the dust removal operation is started, the rotary rotor 48 is rotated in the direction of the arrow by the rotation driving means (not shown), and the rotating rotor 48 is moved up and down by the vertical movement means (not shown). Move upward along the surface. During this time, the rotating rotor 48 scrapes off dust or the like containing oil adhered to the air filter 5. Next, when the rotary rotor 48 reaches the upper end of the air filter 5 by the vertical movement means (not shown), it automatically descends and moves to the lower end of the air filter 5. In the meantime, as in the case of ascent, a device has been devised in which the rotating rotor 48 scrapes off dust or the like containing oil adhered to the air filter 5.

また、ねじりブラシを空気調和機本体に設けて、エアフィルター表面に付着した塵埃を掻き取ることで、エアフィルターを取り外すことなくエアフィルターの自動清掃が行える構造が考案されている。エアフィルター５の塵埃を除去する手段として、図１３のように、2本の金属線を、ブラシを挟み込みながらねじって形成したねじりブラシ５１を、図１１の回転ロータ４８の代わりに、空気調和機本体１に取り付け、ねじりブラシ５１を回転させることによって、ブラシ毛５２の先端部５３をエアフィルター５の網目にくい込ませながら、エアフィルター５に付着した塵埃を掻き落とす装置が考案されている。 Also, a structure has been devised in which a torsion brush is provided on the air conditioner body and the air filter can be automatically cleaned without removing the air filter by scraping off dust adhering to the surface of the air filter. As a means for removing dust from the air filter 5, as shown in FIG. 13, a torsion brush 51 formed by twisting two metal wires while sandwiching the brush is used in place of the rotary rotor 48 of FIG. A device has been devised for scraping off dust adhering to the air filter 5 while rotating the torsion brush 51 by attaching it to the main body 1 and making the tip 53 of the bristles 52 difficult to mesh with the air filter 5.

しかしながら、上記特許文献１に開示されたような従来の空気調和機においては、吸引口の開閉面積を絞ることで風量を落として、吸引圧力を高めている。このような吸引ノズルで塵埃を除去しようとすると、エアフィルター表面に浮いたような状態で乗っている綿埃等は容易に吸引できるが、吸引力のみでは、エアフィルターの格子にこびりついた油分を含む塵埃を清掃体で擦り取ることは出来ず、また、エアフィルターの網目に絡んだ塵埃等を、清掃ブラシのように掻き出して剥離させることもできず、エアフィルターの格子と網目にこびりついた塵埃を確実に除去することは非常に困難であった。 However, in the conventional air conditioner disclosed in Patent Literature 1, the suction pressure is increased by reducing the air volume by reducing the opening / closing area of the suction port. If you try to remove dust with such a suction nozzle, you can easily suck cotton dust that floats on the surface of the air filter, but with the suction force alone, you can remove oil stuck to the grid of the air filter. The dust contained in the air filter mesh cannot be scraped off by the cleaning body, and the dust entangled in the air filter mesh cannot be peeled off like a cleaning brush and stuck to the air filter lattice and mesh. It has been very difficult to reliably remove.

また、図１１、及び図１２の如く考案されたような従来の空気調和機においては、回転ロータ４８を形成する軟質ブレード４９は、エアフィルター５の表面をなでるだけで、たとえ、凸状のリブ部５０を設けても、リブ部５０は軟質ブレード４９の長手方向に連続的に設けられている為、エアフィルター５の格子の隙間や、網目に入り込むことが出来ず、エアフィルター５の表面に浮いたような状態で乗っている綿埃等は除去できるが、エアフィルター５の格子にこびりついた油分を含む塵埃や、エアフィルター５の網目に絡んだ塵埃を完全に剥離させるまで掻き出すことは非常に困難であった。また、軟質ブレード４９のリブ部５０をエアフィルター５に強く接触させて、塵埃の除去効果を上げようとすれば、摩擦抵抗が大きくなり、回転数が低くなってしまい、逆に清掃効果が減少するという問題もあった。また、エアフィルターを傷つけるという問題もあった。 Further, in the conventional air conditioner devised as shown in FIGS. 11 and 12, the soft blade 49 forming the rotating rotor 48 only strokes the surface of the air filter 5, and even if it is a convex rib. Even if the portion 50 is provided, the rib portion 50 is continuously provided in the longitudinal direction of the soft blade 49, so that it cannot enter the gaps or meshes of the lattice of the air filter 5, and does not enter the surface of the air filter 5. Cotton dust and the like that are in a floating state can be removed, but it is very difficult to scrape off dust containing oil stuck to the grid of the air filter 5 or dust entangled in the mesh of the air filter 5 until it completely peels off. It was difficult. Further, if the rib part 50 of the soft blade 49 is brought into strong contact with the air filter 5 to increase the dust removal effect, the frictional resistance increases, the rotational speed decreases, and conversely the cleaning effect decreases. There was also a problem of doing. There was also a problem of damaging the air filter.

また、図１３の如く考案されたような従来の空気調和機においては、ねじりブラシ５１のブラシ毛５２の先端部５３がエアフィルター５の網目に入り込むだけで、エアフィルター５の網目に絡んだ綿埃等の塵埃の除去はできても、エアフィルター５の格子全体を擦る、あるいは拭くことは出来ず、エアフィルター５にこびりついた油分を含む塵埃を確実に除去することは非常に困難であった。また、全長が長いため、ねじりブラシ５１自身、全体が撓み、エアフィルター５に均一に接触しないため、エアフィルター５の格子に接触しない部分と、エアフィルター５の網目にくい込んでしまう部分ができ、接触しない部分は塵埃の除去効果が減り、網目にくい込んでしまう部分はエアフィルター５の抵抗が増し、回転数が減少してしまい、清掃効果が減少するという問題があった。また、ブラシ毛５２は毛の太さが細ければ回転の抵抗は減るが、塵埃の除去効果が減り、逆に太ければ塵埃の除去効果は増すが、エアフィルター５の抵抗が増し、回転抵抗が大きくなるという問題もあった。また、毛が太い場合においては、強い腰でエアフィルター５に当接するために、エアフィルター５自身を痛めてしまうという問題も有していた。 Further, in the conventional air conditioner devised as shown in FIG. 13, the tip 53 of the bristle 52 of the torsion brush 51 only enters the mesh of the air filter 5 and the cotton entangled with the mesh of the air filter 5. Even though dust such as dust could be removed, the entire lattice of the air filter 5 could not be rubbed or wiped off, and it was very difficult to reliably remove dust containing oil stuck to the air filter 5. . In addition, since the entire length is long, the torsion brush 51 itself is bent and does not uniformly contact the air filter 5, so that there is a portion that does not contact the lattice of the air filter 5 and a portion that is difficult to mesh with the mesh of the air filter 5, There is a problem that the dust removal effect is reduced in the non-contact portion, and the resistance of the air filter 5 is increased in the portion where the mesh is difficult to be reduced, the rotation speed is reduced, and the cleaning effect is reduced. Further, the brush hair 52 has a reduced rotational resistance if the bristle is thin, but the effect of removing dust is reduced. Conversely, if the bristle 52 is thick, the effect of removing the dust is increased, but the resistance of the air filter 5 is increased and rotated. There was also a problem that resistance increased. In addition, when the hair is thick, it has a problem that the air filter 5 itself hurts because it contacts the air filter 5 with a strong waist.

本発明は、上記従来の課題を解決するためのもので、エアフィルターの格子と網目に付着し、こびりついた油分を含む塵埃等を、効率よく、確実に除去でき、長期間に亘ってエアフィルターの目詰まりのない状態で使用することができる空気調和機の清掃装置及び、空気調和機を提供することを目的とする。 The present invention is for solving the above-described conventional problems, and is capable of efficiently and surely removing dust or the like that adheres to the lattice and mesh of the air filter and contains oil, and is used for a long time. It is an object of the present invention to provide an air conditioner cleaning device and an air conditioner that can be used without clogging.

前記従来の課題を解決するために、本発明では、本体に設けられた吸込口と吹出口を結ぶ空気通路に、除塵用のエアフィルターを配置してなるエアコンディショナーや送風機、加湿器、除湿機、換気扇、あるいは空気清浄機等の空気調和機において、前記エアフィルターに付着した塵埃を除去する清掃体は、基台に固定される基部と、略帯状の清掃片より構成され、前記清掃片の先端又は／及び側面に、複数の突起部を有しているので、前記エアフィルターに接触する、前記清掃体の略帯状の部分が、前記エアフィルターの表面をむら無く万遍に擦るようにするので、前記エアフィルターの表面に付着しこびりついた油分を含む塵埃等を擦り落とす。また、前記清掃片の先端又は／及び側面の複数の突起部が、前記エアフィルターの格子の凹部と網目に効率よくくい込み引っ掻くので、前記エアフィルターの格子の凹部と網目に付着し絡みついた塵埃を掻き落とすように除去することができる。 In order to solve the above-described conventional problems, in the present invention, an air conditioner, a blower, a humidifier, and a dehumidifier in which an air filter for dust removal is disposed in an air passage connecting a suction port and a blowout port provided in a main body. In an air conditioner such as a ventilation fan or an air purifier, a cleaning body for removing dust adhering to the air filter is composed of a base fixed to a base and a substantially strip-shaped cleaning piece, Since there are a plurality of protrusions at the tip or / and the side surface, the substantially band-shaped portion of the cleaning body that comes into contact with the air filter rubs the surface of the air filter evenly and uniformly. Therefore, dust or the like containing oil adhered to the surface of the air filter is scraped off. In addition, since the plurality of protrusions on the tip and / or side of the cleaning piece efficiently bite and scratch the recesses and meshes of the lattice of the air filter, dust adhering to and entangled with the recesses and meshes of the lattice of the air filter can be removed. It can be removed by scraping.

本発明の清掃体、回転ロータ、及び空気調和機は、前記清掃体が略帯状の清掃片より構成され、前記清掃片の先端又は／及び側面に複数の突起部を有しているので、エアフィルターの格子に付着しこびりついた油分を含む塵埃等も擦り落とすことができる。また、前記清掃体の先端又は／及び側面に複数の突起部を有しているので、前記突起部で前記エアフィルターの格子の凹部と網目に効率よくくい込み、前記エアフィルターに付着し絡みついた塵埃を掻き落とすことができるため、前記エアフィルターから塵埃を完全に剥離、除去させることができる。前記エアフィルターの格子と網目に付着しこびりついた油分を含む塵埃等が除去されることにより、長期間に亘って前記エアフィルターの目詰まりのない状態で使用することができるため、空気調和機の性能も維持され、且つ、前記エアフィルターを取り外して塵埃の清掃を行う必要もなくなる。 In the cleaning body, the rotary rotor, and the air conditioner of the present invention, the cleaning body is configured by a substantially strip-shaped cleaning piece, and has a plurality of protrusions on the tip or / and the side surface of the cleaning piece. Dust and the like containing oil adhering to the filter lattice can be scraped off. In addition, since the cleaning body has a plurality of protrusions on the front end and / or side surface, the protrusions efficiently bite into the recesses and meshes of the lattice of the air filter, and adhere to the air filter and become entangled. Therefore, the dust can be completely peeled off and removed from the air filter. By removing dust or the like containing oil adhering to the grid and mesh of the air filter, it can be used without clogging the air filter for a long period of time. Performance is also maintained, and there is no need to remove the air filter and clean the dust.

図２は、本発明の実施例１における、清掃体７の斜視図である。清掃体７は、基部３６と、側面の先端部１２に突起部１０及び開放端側から基部３６側に向けて任意の長さのスリット１１を有する帯状の清掃片９とで形成されている。清掃体７は、基部３６が基台８へ挿入固定され保持されている。また、突起部１０はエアフィルター５の網目にくい込む大きさで、断続的に形成されている。清掃片９は、略帯状体を有しているので、エアフィルター５の格子に付着しこびりついた油分を含む塵埃等を擦り落とすことができる。また、清掃片９は、先端部１２にスリット１１を有するので、清掃片９は、スリット１１を有しない部分の腰が強く、スリット１１を有する先端部１２は軟らかくなり、エアフィルター５の表面をむら無く万遍に擦るようになり、塵埃の除去効果が増す。また、清掃片９は、エアフィルター５の表面に接触する先端部１２に、エアフィルター５の網目にくい込む大きさの、断続的な突起部１０を有しているので、突起部１０が、エアフィルター５の格子の凹部と網目に効率よくくい込み引っ掻くので、エアフィルター５の格子の凹部と網目に付着し絡みついた塵埃を掻き落とすように除去することができる。 FIG. 2 is a perspective view of the cleaning body 7 in the first embodiment of the present invention. The cleaning body 7 is formed of a base 36 and a strip-shaped cleaning piece 9 having a protrusion 10 on the side end portion 12 and a slit 11 having an arbitrary length from the open end side toward the base portion 36 side. The cleaning body 7 has a base 36 inserted and fixed to the base 8 and is held. Further, the protrusion 10 is intermittently formed in such a size that the mesh of the air filter 5 is difficult to enter. Since the cleaning piece 9 has a substantially band-like body, dust or the like containing oil adhered to the lattice of the air filter 5 can be scraped off. Moreover, since the cleaning piece 9 has the slit 11 in the front-end | tip part 12, the waist of the part which does not have the slit 11 is strong in the cleaning piece 9, and the front-end | tip part 12 which has the slit 11 becomes soft, and the surface of the air filter 5 is made. Evenly rubs evenly, increasing the dust removal effect. Moreover, since the cleaning piece 9 has the intermittent protrusion part 10 of the magnitude | size which can penetrate the mesh | network of the air filter 5 at the front-end | tip part 12 which contacts the surface of the air filter 5, the protrusion part 10 is air-flowing. Since the recesses and the meshes of the grid of the filter 5 are efficiently bitten and scratched, the entangled dust adhering to the grid recesses and the meshes of the air filter 5 can be removed so as to be scraped off.

また、図３のように、清掃体１３は、基部３６と、略帯状の清掃片１５で形成されており、基部３６が基台１４に挿入固定され、清掃体１３が基台１４に保持されている。清掃片１５の先端部１９にエアフィルター５に接触する凸部１６と接触しない凹部１７のような、段差を設けたので、エアフィルター５の格子の凹凸にたいして、むら無く万遍に接触するため、エアフィルター５の格子に付着しこびりついた油分を含む塵埃等を効率よく擦り落とすことができる。また、清掃片１５は、エアフィルター５の表面に接触する先端部１９の凸部１６に、エアフィルター５の網目にくい込む大きさの、断続的な突起部１８を有しており、突起部１８が、エアフィルター５の格子の凹部と網目に効率よくくい込み引っ掻くので、エアフィルター５の格子の凹部と網目に付着し絡みついた塵埃を掻き落とすように除去することができる。また、清掃片１５の先端部１９の段差の形状は、図３の如く、山形形状の他に、図４の如く、凹凸形状や、図５の如く、波形状でも同様の効果が得られるものである。また、図６の如く、突起部１８は、清掃片１５の凸部１６の先端に設けてもよい。 Further, as shown in FIG. 3, the cleaning body 13 is formed by a base 36 and a substantially strip-shaped cleaning piece 15. The base 36 is inserted and fixed to the base 14, and the cleaning body 13 is held by the base 14. ing. Since the step 19 is provided at the tip 19 of the cleaning piece 15 such as the concave portion 17 that does not contact the convex portion 16 that contacts the air filter 5, in order to uniformly contact the unevenness of the lattice of the air filter 5, It is possible to efficiently rub off dust containing oil adhering to the grid of the air filter 5. In addition, the cleaning piece 15 has an intermittent protrusion 18 having a size that is difficult to mesh the mesh of the air filter 5 on the protrusion 16 of the tip 19 that contacts the surface of the air filter 5. However, since it efficiently bites and scratches the recesses and meshes of the lattice of the air filter 5, the dust adhering to and entangled with the recesses and meshes of the lattice of the air filter 5 can be removed so as to be scraped off. In addition to the chevron shape as shown in FIG. 3, the shape of the level difference at the tip 19 of the cleaning piece 15 can be obtained in the same shape as shown in FIG. 4, or the corrugated shape as shown in FIG. It is. As shown in FIG. 6, the protrusion 18 may be provided at the tip of the convex portion 16 of the cleaning piece 15.

また、図７のように、清掃体２０は、基部３６と、帯状の清掃片２２で形成されており、基部３６を基台２１に挿入固定し、清掃体２０が基台２１に保持されている。清掃片２２は、先端部２４が根元部２５にたいして屈曲しており、清掃片２２のエアフィルターに接触する側の先端部２４に複数の突起部２３がエアフィルター５の網目にくい込む大きさで、断続的に形成されている。図８において、清掃体２０が、矢印Ａの方向に移動する際には、清掃片２２の先端部２４が根元部２５より後行しているので、清掃片２２の先端部２４が、前記エアフィルター５の格子の凹凸にたいして、抵抗が少なく、また、むら無く万遍に接触するため、エアフィルター５の格子に付着しこびりついた油分を含む塵埃等を効率よく擦り落とすことができる。また、清掃片２２の先端部２４に設けられた複数の突起部２３が、エアフィルター５の格子の凹部と網目に効率よくくい込み引っ掻くので、前記エアフィルター５の格子の凹部と網目に付着し絡みついた塵埃を掻き落とすように除去することができる。 In addition, as shown in FIG. 7, the cleaning body 20 is formed of a base portion 36 and a strip-shaped cleaning piece 22. The base portion 36 is inserted and fixed to the base 21, and the cleaning body 20 is held by the base 21. Yes. The cleaning piece 22 has a size in which the tip end portion 24 is bent with respect to the root portion 25, and the plurality of protrusions 23 are not easily meshed with the mesh of the air filter 5 in the tip end portion 24 on the side of the cleaning piece 22 that contacts the air filter. It is formed intermittently. In FIG. 8, when the cleaning body 20 moves in the direction of arrow A, the tip 24 of the cleaning piece 22 follows the root 25, so that the tip 24 of the cleaning piece 22 Since there is little resistance to the unevenness of the grid of the filter 5 and the contact is even and uniform, dust containing oil adhered to the grid of the air filter 5 can be efficiently scraped off. Further, since the plurality of protrusions 23 provided at the tip 24 of the cleaning piece 22 efficiently bite and scratch the grid recesses and meshes of the air filter 5, they adhere to and entangle with the grid recesses and meshes of the air filter 5. The dust can be removed so as to scrape off the dust.

また、図８において、エアフィルター５が、矢印Ｂの方向に移動する際には、清掃片２２の先端部２４が根元部２５より先行しているので、清掃片２２の先端部２４が、前記エアフィルター５の格子の凹凸にたいして、抵抗が少なく、また、むら無く万遍に接触するため、エアフィルター５の格子に付着しこびりついた油分を含む塵埃等を効率よく擦り落とすことができる。また、清掃片２２の先端部２４に設けられた複数の突起部２３が、エアフィルター５の格子の凹部と網目に効率よくくい込み引っ掻くので、前記エアフィルター５の格子の凹部と網目に付着し絡みついた塵埃を掻き落とすように除去することができる。 In FIG. 8, when the air filter 5 moves in the direction of arrow B, the distal end portion 24 of the cleaning piece 22 precedes the root portion 25, so that the distal end portion 24 of the cleaning piece 22 is The air filter 5 has less resistance to the unevenness of the lattice of the air filter 5 and contacts evenly and uniformly, so that dust containing oil adhering to the lattice of the air filter 5 can be efficiently scraped off. Further, since the plurality of protrusions 23 provided at the tip 24 of the cleaning piece 22 efficiently bite and scratch the grid recesses and meshes of the air filter 5, they adhere to and entangle with the grid recesses and meshes of the air filter 5. The dust can be removed so as to scrape off the dust.

また、図９のように、清掃体２６は、基台２７に、清掃片Ａ２８、及び清掃片Ｂ２９の、凸部Ａ３０及び凸部Ｂ３２と、凹部Ａ３１及び凹部Ｂ３３が互いに位相差を有して配されるようにしたので、前の清掃片Ａ２８の凸部Ａ３０がエアフィルター５に接触しなかった部分を、次の清掃片Ｂ２８の凸部Ｂ３２が接触することにより、清掃のし残しが無くなり、むら無く万遍に、エアフィルター５の塵埃の除去ができる。また、清掃片の先端部は、上記の段差を有する以外に、突起部やスリットを有する場合も位相差を設けることにより、同様の効果がでる。 Further, as shown in FIG. 9, the cleaning body 26 includes a base 27, a cleaning piece A 28, a cleaning piece B 29, a convex portion A 30 and a convex portion B 32, and a concave portion A 31 and a concave portion B 33 that have a phase difference. Since the projection A30 of the previous cleaning piece A28 does not contact the air filter 5, the projection B32 of the next cleaning piece B28 comes into contact with the portion where the projection A30 of the previous cleaning piece A28 does not come into contact with the air filter 5. The dust from the air filter 5 can be removed evenly and uniformly. Further, in addition to the above-described step difference, the tip of the cleaning piece can provide a similar effect by providing a phase difference even when it has a protrusion or a slit.

次に、本実施例１における空気調和機の清掃装置、及びそれを搭載した空気調和機の動作を説明する。空気調和機本体１を、例えば、冷房運転すると、送風ファン６により、室内の空気が吸込口２から流入し、エアフィルター５を通って熱交換器４に至り、そこで冷却され、冷たい空気が吹き出し口３から室内に吹き出される。吸込口２から吸引される室内の空気に含まれる塵埃は、エアフィルター５で捕集され、エアフィルター５の表面に次第に堆積していく。エアフィルター５の表面に塵埃が堆積してくると、空気の通気圧損が増加し、熱交換器４での熱交換効率が低下してくるので、定期的に或いは、必要に応じて、エアフィルター５に堆積した塵埃の除去運転が必要となる。 Next, the operation of the air conditioner cleaning device and the air conditioner equipped with the same in the first embodiment will be described. When the air conditioner body 1 is cooled, for example, indoor air flows from the suction port 2 by the blower fan 6, passes through the air filter 5, reaches the heat exchanger 4, is cooled there, and cool air blows out. It blows out into the room from the mouth 3. Dust contained in indoor air sucked from the suction port 2 is collected by the air filter 5 and gradually accumulates on the surface of the air filter 5. If dust accumulates on the surface of the air filter 5, air pressure loss of the air increases and the heat exchange efficiency in the heat exchanger 4 decreases. Therefore, the air filter may be periodically or as needed. 5 is required to remove dust accumulated on 5.

塵埃の除去運転の開始に当たり、清掃体７は、エアフィルター５の下端に位置している。塵埃の除去運転を開始すると、清掃体が上下移動手段（図示せず）で、エアフィルター５の表面に沿って上方に移動する。この間に、清掃体７の清掃片９の先端で、エアフィルター５に付着堆積した塵埃が掻き落とされる。 At the start of the dust removal operation, the cleaning body 7 is located at the lower end of the air filter 5. When the dust removal operation is started, the cleaning body moves upward along the surface of the air filter 5 by the vertical movement means (not shown). During this time, the dust adhering to the air filter 5 is scraped off at the tip of the cleaning piece 9 of the cleaning body 7.

次に、上下移動手段（図示せず）により清掃体７が、エアフィルター５の上端まで達すると、自動的に下降し、エアフィルター５の下端まで移動する。この間も上昇時と同様に、清掃体７の清掃片９の先端で、エアフィルター５に付着しこびりついた油分を含む塵埃等が掻き落とされる。 Next, when the cleaning body 7 reaches the upper end of the air filter 5 by the vertical movement means (not shown), it automatically descends and moves to the lower end of the air filter 5. During this time, as in the case of ascent, dust or the like containing oil adhering to and sticking to the air filter 5 is scraped off at the tip of the cleaning piece 9 of the cleaning body 7.

また、本実施例では図示しないが、清掃体７が上下移動せずに、エアフィルター５自身が、清掃体７の清掃片９の先端に接触しながら移動して、エアフィルター５に付着しこびりついた油分を含む塵埃等を除去する構造にしてもよい。 Although not shown in the present embodiment, the cleaning body 7 does not move up and down, and the air filter 5 itself moves while contacting the tip of the cleaning piece 9 of the cleaning body 7 to adhere to the air filter 5 and stick to it. Alternatively, a structure for removing dust or the like containing oil may be used.

The rotary rotor 37 is formed by inserting a cleaning body 44 into a support groove 39 of a rotor 38 serving as a rotation shaft, and has a protrusion 43 on a convex portion 41 of a tip 46 of a cleaning piece 40 constituting the cleaning body 44. The rotating rotor 37 is attached so that the tip 46 of the cleaning piece 40 contacts the air filter 5. The cleaning piece 40 is formed on the surface of the air filter 5 as a belt-like body having a convex portion 41 that intermittently contacts the concave portion 42 where the tip portion 46 does not continuously contact. Moreover, the convex part 41 and the recessed part 42 of the some cleaning piece 40 are arrange | positioned so that the air filter 5 may be contacted in a mutually different position. A bracket 47 is attached to both ends of the rotor 38 to fix the rotary rotor 37 to the cleaning device. When the rotating rotor 37 rotates, every time the convex portions 41 of the plurality of cleaning pieces 40 come into contact with the air filter 5 alternately, the unevenness of the lattice of the air filter 5 is uniformly contacted. It is possible to efficiently rub off dust or the like that adheres to the lattice and contains oil. Further, the cleaning piece 40 has an intermittent protrusion 43, which is large enough to fit into the mesh of the air filter 5, on the convex portion 41 of the tip 46 that contacts the surface of the air filter 5. However, since the concave portions and the meshes of the lattice of the air filter 5 are efficiently bitten and scratched, the dust adhering to and entangled with the concave portions of the lattice and the mesh of the air filter 5 can be removed so as to be scraped off.

また、回転ロータ３７は、先端部４６に山形形状段差の凸部４１、及び凹部４２を有する清掃片４０で形状で説明したが、先端部の形状は、スリット、凹凸形状や波形形状でもよい。 Further, the rotary rotor 37 has been described in terms of the shape of the cleaning piece 40 having the convex portion 41 and the concave portion 42 of the chevron-shaped step at the distal end portion 46, but the shape of the distal end portion may be a slit, an uneven shape, or a corrugated shape.

また、図１０に示すように、ロータ３８の支持溝３９を、長手方向の軸の周りに螺旋状に形成して、清掃片４０が螺旋状に捩られた回転ロータ３７を形成しているので、回転ロータ３７が回転すると、清掃片４０は連続的に滑らかに、かつ均一に、エアフィルター５の表面に当たるため、音が静かで、むら無く万遍に、効率よく確実に塵埃を除去することができる。 Further, as shown in FIG. 10, the support groove 39 of the rotor 38 is formed in a spiral shape around the longitudinal axis, and the rotary rotor 37 in which the cleaning piece 40 is helically twisted is formed. When the rotary rotor 37 is rotated, the cleaning piece 40 continuously and smoothly hits the surface of the air filter 5, so that the sound is quiet and the dust is uniformly and efficiently removed without fail. Can do.

次に、本実施例２における空気調和機の回転ロータ３７及びそれを搭載した空気調和機の動作を説明する。図１１の従来の空気調和機本体１の回転ロータ４８の代わりに、本発明の実施例２における回転ロータ３７を取り付けて説明する。塵埃の除去運転の開始に当たり、回転ロータ３７は、エアフィルター５の下端に位置している。塵埃の除去運転を開始すると、回転駆動手段（図示せず）により回転ロータ３７が矢印の方向に回転すると共に、その回転する回転ロータ３７が上下移動手段（図示せず）で、エアフィルター５の表面に沿って上方に移動する。この間に、回転ロータ３７の清掃片４０の先端で、エアフィルター５に付着しこびりついた油分を含む塵埃等が掻き落とされる。 Next, the operation of the rotary rotor 37 of the air conditioner and the air conditioner equipped with the same according to the second embodiment will be described. Instead of the rotating rotor 48 of the conventional air conditioner body 1 of FIG. 11, a rotating rotor 37 according to the second embodiment of the present invention will be attached and described. At the start of the dust removal operation, the rotary rotor 37 is positioned at the lower end of the air filter 5. When the dust removal operation is started, the rotary rotor 37 is rotated in the direction of the arrow by the rotation driving means (not shown), and the rotating rotor 37 is moved up and down by the vertical movement means (not shown).

During this time, similarly to the time of ascent, dust or the like containing oil adhered to the air filter 5 is scraped off at the tip of the cleaning piece 40 of the rotary rotor 37.

回転ロータ３７は、回転しながらエアフィルター５に接触しながら移動するため、回転ロータ３７によって、強力にエアフィルター５に付着した塵埃や、こびりついた油分を含む塵埃を掻き出して除去することができる。 Since the rotating rotor 37 moves while contacting the air filter 5 while rotating, the rotating rotor 37 can scrape and remove the dust adhering to the air filter 5 and the dust containing the sticking oil.

また、本実施例では図示しないが、回転ロータ３７が上下移動せずに、エアフィルター５自身が、回転する回転ロータ３７の清掃片４０の先端に接触しながら移動して、エアフィルター５に付着しこびりついた油分を含む塵埃等を除去する構造にしてもよい。 Although not shown in the present embodiment, the rotary rotor 37 does not move up and down, and the air filter 5 itself moves while contacting the tip of the cleaning piece 40 of the rotating rotor 37 and adheres to the air filter 5. A structure may be used to remove dust and the like containing oil.

また、上記の実施例１、または２に説明した清掃片の材質は、エアフィルター５に接触する先端部に、スリット、凸部、凹部、及び突起部を有する、帯状の軟質の合成樹脂で成形されている。軟質の合成樹脂で成形された清掃片は、エアフィルターの格子の凹凸にたいして、むら無く万遍に接触するため、エアフィルターの格子に付着しこびりついた油分を含む塵埃等を効率よく擦り落とすことができる。また、清掃片の材質は、帯状の布帛に、合成樹脂で突起部を一体成形してもよい。 Moreover, the material of the cleaning piece described in the first or second embodiment is formed of a strip-shaped soft synthetic resin having a slit, a convex portion, a concave portion, and a protruding portion at a tip portion that contacts the air filter 5.
