Description

本発明は、空気調和機に取り付けられたエアフィルターの清掃を行う空気調和機用回転ロータと、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 a rotary rotor for an air conditioner that cleans an air filter attached to the air conditioner, and an air conditioner using the same.

空気調和機に取り付けられたエアフィルターに堆積した塵埃を除去する従来の方法として、塵埃吸引用の吸引孔を設けた吸引ノズルと、前記吸引ノズルに連結された吸引装置とを備え、前記吸引ノズルをエアーフィルターの上流側表面に沿って移動させて、エアフィルター上に堆積した塵埃を吸引するようにしたものがある（例えば、特許文献１参照）。しかしながら、上記特許文献1に記載されたエアフィルターの清掃方法では、空気調和機の冷房運転時に発生する湿気などにより、エアーフィルターの表面にこびりついた塵埃が取れ難く、また、塵埃が取れ易いように、吸引力を高めるために、吸引ノズルに設けた吸引孔を狭めると、広いエアーフィルターの全面を清掃するのに時間がかかるといった問題があった。   As a conventional method for removing dust accumulated on an air filter attached to an air conditioner, the suction nozzle includes a suction nozzle provided with a suction hole for dust suction and a suction device connected to the suction nozzle. Is moved along the upstream surface of the air filter to suck dust accumulated on the air filter (see, for example, Patent Document 1). However, in the air filter cleaning method described in Patent Document 1 above, it is difficult to remove dust adhered to the surface of the air filter due to moisture generated during the cooling operation of the air conditioner, and it is easy to remove dust. When the suction hole provided in the suction nozzle is narrowed in order to increase the suction force, there is a problem that it takes time to clean the entire surface of the wide air filter.

これを改善する方法として、外周長手方向にブラシ状の清掃体を植毛した空気調和機用回転ロータでエアフィルターの表面に付着した塵埃を強制的に除去するようにしたものもある（例えば、特許文献２参照）。   As a method for improving this, there is a method in which dust attached to the surface of the air filter is forcibly removed by a rotary rotor for an air conditioner in which a brush-like cleaning body is planted in the longitudinal direction of the outer periphery (for example, a patent) Reference 2).

図７は、上記特許文献２に記載された従来の空気調和機用回転ロータを搭載した空気調和機の縦断面図、図８は、同空気調和機用回転ロータの斜視図である。   FIG. 7 is a longitudinal sectional view of an air conditioner equipped with the conventional air conditioner rotary rotor described in Patent Document 2, and FIG. 8 is a perspective view of the air conditioner rotary rotor.

図７において、空気調和機本体１内には、熱交換器２と、室内の空気を取り入れる吸込口３と、前記熱交換器２と前記吸込口３の間に設けられたベルト状のエアフィルター４と、このエアフィルター４を張設した駆動軸６および従動軸７と、前記駆動軸６を回転駆動するサーボモーター５と、前記フィルター４で捕集された塵埃を除去する空気調和機用回転ロータ８（以下、「回転ロータ８」という）と、前記回転ロータ８を回転駆動する駆動手段（図示せず）と、前記吸込口３と連通すると共に前記回転ロータ８を内設し排出口９を有する排気管１０と、前記排気管１０内に設けられた塵埃排出用ファン１１と、前記吸込口３から室内の空気を吸引し、熱交換器２を通して吹き出し口１２から、熱交換された空気を室内に吹き出すファン１３とを備えている。   In FIG. 7, in the air conditioner main body 1, a heat exchanger 2, a suction port 3 for taking in indoor air, and a belt-like air filter provided between the heat exchanger 2 and the suction port 3. 4, a drive shaft 6 and a driven shaft 7 on which the air filter 4 is stretched, a servo motor 5 that rotationally drives the drive shaft 6, and an air conditioner rotation that removes dust collected by the filter 4 A rotor 8 (hereinafter referred to as “rotary rotor 8”), a driving means (not shown) for rotationally driving the rotary rotor 8, and the suction port 3 are communicated with the rotary rotor 8 and a discharge port 9 is provided. The exhaust pipe 10 having the above, the dust discharge fan 11 provided in the exhaust pipe 10, and the indoor air is sucked from the suction port 3, and the heat-exchanged air is discharged from the blowout port 12 through the heat exchanger 2. Fan 1 It is equipped with a door.

回転ロータ８は、図８に示すように、樹脂からなる回転自在のロータ８ａと、前記ロータ８ａの外周の長手方向に直線状に植設されたブラシ状の清掃体８ｂから構成されている。   As shown in FIG. 8, the rotary rotor 8 is composed of a rotatable rotor 8a made of resin, and a brush-like cleaning body 8b planted linearly in the longitudinal direction of the outer periphery of the rotor 8a.

上記構成による回転ロータと空気調和機の動作、作用は以下の通りである。   The operation and action of the rotary rotor and air conditioner configured as described above are as follows.

空気調和機本体１を、例えば、冷房運転すると、ファン１３により室内の空気が吸込口３から流入し、エアフィルター４を通って熱交換器２に至り、そこで冷却され、冷たい空気が吹き出し口１２から室内に吹き出される。吸引される室内の空気に含まれる塵埃は、前記エアフィルター４で捕集され、フィルター４の表面に堆積する。エアフィルター４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４上の塵埃の除去運転が必要となる。   When the air conditioner main body 1 is in a cooling operation, for example, indoor air flows from the inlet 3 by the fan 13, passes through the air filter 4, reaches the heat exchanger 2, and is cooled there. Is blown out into the room. Dust contained in the indoor air to be sucked is collected by the air filter 4 and deposited on the surface of the filter 4. If dust accumulates on the surface of the air filter 4, the air pressure loss of air increases and the heat exchange efficiency decreases. Therefore, the dust on the air filter 4 can be removed periodically or as necessary. Driving is required.

塵埃の除去運転は、サーボモーター５を運転して駆動軸６を回転させてベルト状のフィルター４を連続的に移動させ、その間に回転ロータ８を回転させると共に塵埃排出用ファン１１を運転するもので、エアフィルター４上の塵埃が、回転ロータ８の清掃体8ｂで掻き取られ、掻き取られた塵埃は、塵埃排出用ファン１１により吸引され、排出口９より室外に排出されるようになっている。   In the dust removal operation, the servo motor 5 is operated to rotate the drive shaft 6 to continuously move the belt-like filter 4, while the rotary rotor 8 is rotated and the dust discharge fan 11 is operated. Thus, the dust on the air filter 4 is scraped by the cleaning body 8b of the rotary rotor 8, and the scraped dust is sucked by the dust discharge fan 11 and discharged from the discharge port 9 to the outside. ing.

しかしながら、上記特許文献２に開示された回転ロータ８は、樹脂などからなるロータ８ａに清掃体８ｂを植毛して構成しているため、製造コストが高く、また、強度を確保する観点からロータ８ａが太くなるという問題があった。又、前記清掃体８ｂは、網目状のエアフィルター４上の塵埃を掻き取るため消耗していくが、ロータ８ａに植設されているため、それ自体の交換は不可能で、回転ロータ８全体を交換する必要があり、維持費用が高価になるという問題があった。   However, since the rotary rotor 8 disclosed in Patent Document 2 is configured by flocking the cleaning body 8b on the rotor 8a made of resin or the like, the rotor 8a is high in manufacturing cost and secures strength. There was a problem that became thick. The cleaning body 8b is consumed to scrape the dust on the mesh-like air filter 4. However, since the cleaning body 8b is implanted in the rotor 8a, it is impossible to replace the cleaning body 8b. There is a problem that the maintenance cost becomes expensive.

上記問題を解決するために、本来の使用用途は、電気掃除機用であるが、アルミニュームなどの金属材料からなり、外周面に螺旋状の複数の溝を有する回転ロータと、前記溝に下端が着脱自在に装着される清掃体とで構成した回転ロータがある（例えば、特許文献３、４参照）。このような回転ロータの場合は、ロータが金属材料で形成されているので、強度が上がり、その分ロータの径が小さくできると共に、清掃体の交換が容易になるというメリットを有している。
特開２００５−１４０４０５号公報 特開平６−７４５２１号公報 特開２００１−１６１６１１号公報 特開平１１−９５２２号公報 In order to solve the above problem, the original use is for a vacuum cleaner, but it is made of a metal material such as aluminum and has a rotating rotor having a plurality of spiral grooves on the outer peripheral surface, and a lower end in the groove. There is a rotary rotor that is configured with a cleaning body that is detachably mounted (for example, see Patent Documents 3 and 4). In the case of such a rotating rotor, since the rotor is formed of a metal material, the strength is increased, and the diameter of the rotor can be reduced correspondingly, and the cleaning body can be easily replaced.

ロータをアルミニュームなどの金属材料で形成し、それに清掃体取り付け用の溝を螺旋状に設ける場合、一般的な製法として、１）捩り押出し金型にて、ロータの材料を捩りながら押出す、２）ロータの材料を一旦まっすぐに押出して、後加工で、目的の捩り角度まで捩って仕上げるなどの方法があるが、いずれの場合も、捩り加工時に、ロータに反りが発生するが、電気掃除機用の回転ロータは、床吸込具に装着されるようになっているので、長さもせいぜい２０〜３０ｃｍ程度で、前記反りもさほど大きな問題とならない。仮に、製造工程で、大きな反りが発生した場合でも、図９に示すように定盤３４でロータを転がして、その反りを実用的に問題ない範囲で容易に矯正することが出来る。   When the rotor is formed of a metal material such as aluminum and the groove for attaching the cleaning body is provided in a spiral shape, as a general manufacturing method, 1) Extrude while twisting the rotor material with a twisting extrusion mold, 2) There is a method of extruding the rotor material straight once and finishing by twisting to the target twist angle in the post-processing. In either case, the rotor warps during the twisting process. Since the rotary rotor for a vacuum cleaner is designed to be attached to a floor suction tool, the length is at most about 20 to 30 cm, and the warpage is not a significant problem. Even if a large warp occurs in the manufacturing process, the rotor can be rolled by the surface plate 34 as shown in FIG. 9, and the warp can be easily corrected within a practically no problem range.

しかしながら、空気調和機用回転ロータの場合は、それが清掃するエアフィルターの幅が３００ｍｍ以上と広く、時には、左右に配置された２つのエアフィルターを同時に清掃できるように６００ｍｍ以上と長く形成する必要があり、しかも、電気掃除機用の回転ロータと異なり、低速で回転して使用されるため、製造工程で発生する反りを、より精度よく、確実に矯正する必要がある。   However, in the case of a rotary rotor for an air conditioner, the width of the air filter to be cleaned is as wide as 300 mm or more, and sometimes it is necessary to form it as long as 600 mm or more so that the two air filters arranged on the left and right can be cleaned simultaneously. In addition, unlike a rotary rotor for an electric vacuum cleaner, it is used by rotating at a low speed, so it is necessary to more accurately and reliably correct the warp generated in the manufacturing process.

本発明は、上記従来の課題を解決するもので、ロータの製造工程で発生する反りを、精度よく確実に矯正することができる空気調和機用回転ロータとそれを用いた空気調和機を提供することを目的とするものである。   The present invention solves the above-described conventional problems, and provides a rotary rotor for an air conditioner that can accurately and reliably correct warpage that occurs in the manufacturing process of the rotor, and an air conditioner using the same. It is for the purpose.

前記従来の課題を解決するために、本発明の空気調和機用回転ロータは、空気調和機に取着されたエアフィルターに堆積した塵埃を除去し、全長が少なくとも３００ｍｍのロータを有する空気調和機用回転ロータであって、前記ロータは、軽合金材料で形成されると共に外周の長手方向に複数条の支持溝が前記ロータの長手方向の軸の周りに螺旋状に形成されており、該支持溝に一端が挿入され、他端が前記支持溝の開口より突出して前記エアフィルター上の塵埃を掻き取る清掃体を備え、前記ロータの隣り合う２つの前記支持溝間に位置する全ての外周部における最も突出した先端部分の回転軌跡を同一にし、且つ該突出した先端部分が前記ロータの隣り合う２つの前記支持溝間の一方の支持溝側に近くなるように偏らせて形成されてあることに特徴を有する。   In order to solve the above-described conventional problems, the rotary rotor for an air conditioner according to the present invention removes dust accumulated on an air filter attached to the air conditioner and has a rotor having a total length of at least 300 mm. The rotor is made of a light alloy material, and a plurality of support grooves are formed in a spiral shape around the longitudinal axis of the rotor in the longitudinal direction of the outer periphery. All outer peripheral portions located between two adjacent support grooves of the rotor, each having a cleaning body having one end inserted into the groove and the other end protruding from the opening of the support groove and scraping off dust on the air filter Are formed so as to have the same rotation trajectory of the most protruding tip portion, and so that the protruding tip portion is biased closer to one of the support grooves between the two adjacent support grooves of the rotor. Door to having the features.

また、本発明の空気調和機は、熱交換器と、該熱交換器の上流側に配され流入する空気中に含まれる塵埃を捕獲するエアフィルターと、請求項１に記載の空気調和機用回転ロータと、該回転ロータを回転させる回転駆動手段と、該回転ロータを前記エアフィルターの上流側に配置し、前記エアフィルターの表面に沿って移動させる上下方向移動手段とを備えたことに特徴を有する。   The air conditioner of the present invention is a heat exchanger, an air filter that is disposed upstream of the heat exchanger and captures dust contained in the flowing air, and the air conditioner according to claim 1. A rotary rotor, a rotary drive unit that rotates the rotary rotor, and a vertical movement unit that is arranged upstream of the air filter and moves along the surface of the air filter. Have

本発明の空気調和機用回転ロータは、ロータの製造工程で発生する反りを、精度良く確実に矯正することができるものである。   The rotary rotor for an air conditioner according to the present invention is capable of accurately and reliably correcting warpage that occurs in the manufacturing process of the rotor.

本発明は、空気調和機に取着されたエアフィルターに堆積した塵埃を除去し、全長が少なくとも３００ｍｍのロータを有する空気調和機用回転ロータであって、前記ロータは、軽合金材料で形成されると共に外周の長手方向に複数条の支持溝を有し、前記支持溝に一端が挿入固定され、他端が前記支持溝の開口より突出して前記エアフィルター上の塵埃を掻き取る清掃体を備え、前記ロータの隣り合う２つの前記支持溝間に位置する全ての外周部におけるもっとも突出した部分の先端の回転軌跡を同一にしたもので、前記ロータの反り矯正時に、ロータと定盤との間や、ロータとローラー間でのがたつきが少なくなるので、反りの矯正が容易で且つ確実にでき、仕上がり精度の高い空気調和機用回転ロータを提供することができる。   The present invention is a rotary rotor for an air conditioner having a rotor with a total length of at least 300 mm, which removes dust accumulated on an air filter attached to the air conditioner, and the rotor is made of a light alloy material. And a cleaning body having a plurality of support grooves in the longitudinal direction of the outer periphery, one end inserted and fixed in the support groove, and the other end protruding from the opening of the support groove to scrape off dust on the air filter. , The rotation trajectory of the tip of the most protruding part in all the outer peripheral parts located between the two adjacent support grooves of the rotor is the same, and during the correction of the warp of the rotor, between the rotor and the surface plate In addition, since rattling between the rotor and the roller is reduced, it is possible to provide a rotary rotor for an air conditioner that can easily and reliably correct warpage and has high finishing accuracy.

本発明は、特に、複数条の支持溝を、ロータの長手方向の軸の周りに螺旋状に形成したもので、支持溝の開口近傍の外径が、ロータの最大回転外径より小さい場合でも、その部分が、その支持溝と隣の支持溝との間に位置すると共にロータの最大回転外径と同じ外径の外周部で支持されるので、前記ロータの反り矯正時に、ロータと定盤との間や、ロータとローラー間でのがたつきがより少なくなり、反りの矯正がより容易になり、仕上がり精度の高い空気調和機用回転ロータを提供することができる。   In the present invention, in particular, a plurality of support grooves are spirally formed around the longitudinal axis of the rotor, and even when the outer diameter near the opening of the support groove is smaller than the maximum rotation outer diameter of the rotor. The portion is located between the support groove and the adjacent support groove and is supported by the outer peripheral portion having the same outer diameter as the maximum rotation outer diameter of the rotor. Therefore, when correcting the warpage of the rotor, the rotor and the surface plate It is possible to provide a rotary rotor for an air conditioner with high finishing accuracy, in which the backlash between the rotor and the roller is less, the warp is more easily corrected.

本発明は、空気調和機に、空気を熱交換する熱交換器と、前記熱交換器の上流側に配され流入する空気中に含まれる塵埃を捕獲するエアフィルターと、上述の空気調和機用回転ロータとを備えたもので、ロータの反りが非常に小さいので、回転ロータの回転時の騒音を低減するために、回転ロータの回転数を落としても、エアフィルターの全幅に渡って確実に塵埃を掻き取ることができる。   The present invention provides an air conditioner having a heat exchanger that exchanges heat with air, an air filter that is disposed upstream of the heat exchanger and that captures dust contained in the flowing air, and the above-described air conditioner With a rotating rotor, the warpage of the rotor is very small, so in order to reduce the noise during rotation of the rotating rotor, even if the rotational speed of the rotating rotor is reduced, it is ensured over the entire width of the air filter. Dust can be scraped off.

There are various methods, such as a method of providing a movable board rotating in the torsional direction on the line and extruding the material of the rotor 30 with a mold while simultaneously twisting to finish the target torsion angle. The manufacturing method and the processing method may be appropriately determined in consideration of the cross-sectional shape, material, thickness, strength, twist angle, required accuracy, and the like.

また、本実施例では、回転ロータ２５の有効清掃幅Ｌ３が、３００ｍｍ以上と、長尺なので、ロータ３０の製造時に発生する反りが全体で大きくなり、矯正が必要となってくるが、具体的には、従来のように定盤３４上でロータ３０を転がして行なう方法（図９）、あるいは、図５に示すように、少なくとも三つの棒状のローラー３５でロータ３０を挟持しながら転がして、矯正するなどの方法がある。   Further, in this embodiment, since the effective cleaning width L3 of the rotary rotor 25 is as long as 300 mm or more, the warpage generated at the time of manufacturing the rotor 30 becomes large as a whole, and correction is necessary. In the conventional method, the rotor 30 is rolled on the surface plate 34 (FIG. 9), or, as shown in FIG. 5, the rotor 30 is rolled while being sandwiched by at least three rod-shaped rollers 35. There are methods such as correcting.

清掃体３２は、図３（ｄ）に示すように、多数の極細繊維などからなるブラシ部３２ａと、ブラシ部３２ａの下端を固定すると共に、ロータ３０に設けた支持溝３１に着脱自在に装着される基部３２ｂから構成されている。尚、ブラシ部３２ａは、繊維などに限らず、塩化ビニールなどの軟質材からなるブレード状のもの、或いは不織布で形成しても良い。またブラシ部３２ａと基部３２ｂとの固定は、ブラシ部３２ａを基部３２ｂに植設したり、両者を接着したり、或いは、一方を他方で挟むようにするなどその方法は特に限定しない。   As shown in FIG. 3 (d), the cleaning body 32 fixes a brush portion 32 a made of a large number of ultrafine fibers and the lower end of the brush portion 32 a and is detachably attached to a support groove 31 provided in the rotor 30. The base portion 32b is configured. The brush portion 32a is not limited to fibers, but may be formed of a blade-like material made of a soft material such as vinyl chloride, or a non-woven fabric. The method of fixing the brush portion 32a and the base portion 32b is not particularly limited, for example, the brush portion 32a is implanted in the base portion 32b, the two are bonded, or one is sandwiched between the other.

以上のように構成された空気調和機用回転ロータを搭載した空気調和機の動作、作用は、以下の通りである。   The operation and action of the air conditioner equipped with the air conditioner rotary rotor configured as described above are as follows.

空気調和機本体２０を例えば、冷房運転すると、ファン２７の運転により室内の空気が吸込口２２から流入し、エアフィルター２３を通って熱交換器２１に至り、そこで冷却され、冷たい空気が吹き出し口２６から室内に吹き出される。吸込口２２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２３で捕獲され、そのエアフィルター２３の表面に次第に堆積していく。エアフィルター２３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２１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２３に堆積した塵埃の除去運転が必要となる。   For example, when the air conditioner body 20 is in a cooling operation, indoor air flows from the suction port 22 by the operation of the fan 27, passes through the air filter 23, reaches the heat exchanger 21, and is cooled there. 26 is blown into the room. Dust contained in indoor air sucked from the suction port 22 is captured by the air filter 23 and gradually accumulates on the surface of the air filter 23. If dust accumulates on the surface of the air filter 23, the air pressure loss of air increases and the heat exchange efficiency in the heat exchanger 21 decreases. Therefore, the air filter is periodically or as needed. The operation of removing the dust accumulated on 23 is required.

そこで、本実施例では、塵埃の除去運転を開始すると、図２に示すように、エアフィルター２３の下端に位置していた回転ロータ２５が、回転駆動手段（図示せず）により矢印方向（時計方向）に回転しながら、上下移動手段（図示せず）で、エアフィルター２３の表面に沿って上方に移動する。この間に、清掃体３２のブラシ部３２ａの先端で、エアフィルター２３の上流側表面に付着堆積した塵埃が掻き落とされる。掻き落とされた塵埃は、図示しない塵埃吸引手段で吸引されると共に、屋外に排出されるようになっている。   Therefore, in this embodiment, when the dust removal operation is started, as shown in FIG. 2, the rotary rotor 25 located at the lower end of the air filter 23 is moved in the direction of the arrow (clockwise) by the rotation drive means (not shown). While moving in the direction), the upper and lower moving means (not shown) moves upward along the surface of the air filter 23. During this time, dust adhering to the upstream surface of the air filter 23 is scraped off at the tip of the brush portion 32a of the cleaning body 32. The dust scraped off is sucked by a dust suction means (not shown) and discharged to the outdoors.

なお、上下移動手段により、回転ロータ２５が、エアフィルター２３の上端まで達すると、自動的に下降し、次回の塵埃の除去運転用に、エアフィルター２３の下端で停止するようになっている。また、回転ロータ２５の回転方向は、矢印方向と反対方向（反時計方向）であっても良く、その回転方向は、清掃性能等を考慮しながら適宜決定すればよい。   When the rotary rotor 25 reaches the upper end of the air filter 23 by the vertical movement means, it automatically descends and stops at the lower end of the air filter 23 for the next dust removal operation. Further, the rotation direction of the rotary rotor 25 may be the direction opposite to the arrow direction (counterclockwise direction), and the rotation direction may be appropriately determined in consideration of the cleaning performance and the like.

以上のように、本実施例によれば、ロータ３０の隣り合う２つの支持溝３１間に位置する全ての外周部３０ａ（本実施例では、４箇所）におけるもっとも突出した部分の先端３０ｃの回転軌跡（直径がＬの円）が同一になるようにしているので、ロータ３０の反り矯正時に、ロータ３０と定盤３４との間や、ロータ３０とローラー３５間でのがたつきが少なくなり、３００ｍｍ以上の長いロータ３０でも、反りの矯正が容易になり、仕上がり精度の高い空気調和機用回転ロータを提供することができる。   As described above, according to this embodiment, the rotation of the tip 30c of the most protruding portion of all the outer peripheral portions 30a (four in this embodiment) located between the two adjacent support grooves 31 of the rotor 30 is performed. Since the trajectories (circles having a diameter L) are the same, rattling between the rotor 30 and the surface plate 34 and between the rotor 30 and the roller 35 is reduced when the rotor 30 is warped. Even with a long rotor 30 of 300 mm or more, it becomes easy to correct warpage, and a rotary rotor for an air conditioner with high finishing accuracy can be provided.

また、ロータ３０を、比重の軽いマグネシウム合金、アルミニューム合金、チタン合金などの軽合金材料で形成しているので、ロータ３０が空気調和機用に長尺に形成されても空気調和機全体の重さの中では微々たるもので、一般に壁に取り付けられる空気調和機に重量的に大きな負担をかけることがない。   Further, since the rotor 30 is made of a light alloy material such as magnesium alloy, aluminum alloy or titanium alloy having a light specific gravity, even if the rotor 30 is formed long for an air conditioner, the entire air conditioner It is insignificant in weight and generally does not place a heavy burden on the air conditioner attached to the wall.

又、複数条の支持溝３１を、ロータの長手方向の軸の周りに螺旋状に形成することにより、図６に示すように、支持溝３１の開口３１ａ近傍での外径Ｌ１が、ロータ３０の最大回転外径Ｌ０より小さい場合でも、その部分が、その支持溝３１と隣の支持溝３１’との間に位置すると共にロータ３０の最大回転外径Ｌ０と同じ外径の外周部３０ａによって、ロータ３０の長手方向で位置はずれるものの支持されるので、前記ロータ３０の反り矯正時に、ロータ３０と定盤３４との間や、ロータ３０とローラー３５間でのがたつきがより少なくなり、反りの矯正が容易になり、仕上がり精度の高い空気調和機用回転ロータを提供することができる。本実施例では、支持溝３１が４つ設けられているので、支持溝３１の捩り角度を、ロータ３０の一方の端から他方の端にかけて、３６０度÷４、すなわち９０度に設定している。特に図示しないが、ロータ３０に、一対の支持溝３０を対向して設けた場合は、その支持溝３１の捩り角度を１８０度以上にすると良い。   Further, by forming a plurality of support grooves 31 spirally around the longitudinal axis of the rotor, as shown in FIG. 6, the outer diameter L1 in the vicinity of the opening 31a of the support groove 31 is reduced to the rotor 30. Is smaller than the maximum rotation outer diameter L0 of the rotor 30, and the portion is located between the support groove 31 and the adjacent support groove 31 ′, and the outer peripheral portion 30a has the same outer diameter as the maximum rotation outer diameter L0 of the rotor 30. Since the rotor 30 is displaced in the longitudinal direction, it is supported, so that when the warpage of the rotor 30 is corrected, rattling between the rotor 30 and the surface plate 34 or between the rotor 30 and the roller 35 is reduced. It is possible to provide a rotary rotor for an air conditioner that is easy to correct warpage and has high finishing accuracy. In this embodiment, since four support grooves 31 are provided, the twist angle of the support groove 31 is set to 360 degrees / 4, that is, 90 degrees from one end of the rotor 30 to the other end. . Although not particularly illustrated, when a pair of support grooves 30 are provided opposite to the rotor 30, the twist angle of the support grooves 31 is preferably 180 degrees or more.

また、空気を熱交換する熱交換器２１と、前記熱交換器２１の上流側に配され流入する空気中に含まれる塵埃を捕獲するエアフィルター２３と、上記実施の形態で述べた回転ロータ２５とを、空気調和機本体２０に備えることにより、ロータ３０の反りが非常に小さいので、回転ロータ３０の回転時の騒音が低く、また回転ロータ２５の回転数を落としても、エアフィルター２３の全幅に渡って確実に塵埃を掻き取ることができるもので、メンテナンスの容易な空気調和機を提供することができる。   In addition, the heat exchanger 21 that exchanges heat with the air, the air filter 23 that is arranged upstream of the heat exchanger 21 and captures dust contained in the inflowing air, and the rotary rotor 25 described in the above embodiment. Is provided in the air conditioner main body 20 so that the warpage of the rotor 30 is very small, so that noise during rotation of the rotary rotor 30 is low, and even if the rotational speed of the rotary rotor 25 is reduced, the air filter 23 Since the dust can be surely scraped over the entire width, an air conditioner with easy maintenance can be provided.

又、清掃体３２の基部３２ｂが、ロータ３０の支持溝３１に対し挿脱自在なので、回転ロータ２５の組み立てが容易である。また、清掃体３２は、網目状のエアフィルター２３上の塵埃を掻き取るため、消耗が激しいが、その基部３２ｂが、ロータ３０の支持溝３１に挿脱自在なので、清掃体３２が消耗したときに、回転ロータ２５全体を交換する必要が無く、清掃体３２のみの交換で済むので、空気調和機の維持費用が安価である。   Further, since the base portion 32 b of the cleaning body 32 can be inserted into and removed from the support groove 31 of the rotor 30, the assembly of the rotary rotor 25 is easy. Further, the cleaning body 32 scrapes off dust on the mesh-like air filter 23, so that the cleaning body 32 wears heavily. In addition, since it is not necessary to replace the entire rotary rotor 25 and only the cleaning body 32 is replaced, the maintenance cost of the air conditioner is low.

又、支持溝３１が、ロータ３０の外周長手方向に螺旋状に形成されているので、その支持溝３１に、清掃体３２の基部３２ｂを挿入することで、清掃体３２のブラシ部３２ａが螺旋状に配置され、それによってブラシ部３２ａの先端がエアフィルター２３に部分的に接して、摺動抵抗が分散されるので、回転ロータ２５を回転駆動する回転駆動手段を小型化することが出来ると共に、エアフィルター２３をむら無く、均一に清掃することができる。   Further, since the support groove 31 is formed in a spiral shape in the outer circumferential longitudinal direction of the rotor 30, the brush portion 32 a of the cleaning body 32 is spiraled by inserting the base portion 32 b of the cleaning body 32 into the support groove 31. Since the tip of the brush portion 32a is partially in contact with the air filter 23 and the sliding resistance is dispersed, the rotational drive means for rotationally driving the rotary rotor 25 can be reduced in size. The air filter 23 can be uniformly cleaned without unevenness.

又、ロータ３０を金属材で形成することにより、強度が高まり、その分、ロータ３０をより小径に形成することができ、省スペース化となる。   Further, by forming the rotor 30 with a metal material, the strength is increased, and accordingly, the rotor 30 can be formed with a smaller diameter, thereby saving space.

なお、上記実施例では、２個のエアフィルター２３のそれぞれに回転ロータ２５を設けたが、一本の長尺の回転ロータ２５で、２個のエアフィルター２３の清掃を同時に行うようにしても良い。   In the above-described embodiment, each of the two air filters 23 is provided with the rotating rotor 25. However, the two air filters 23 may be simultaneously cleaned with one long rotating rotor 25. good.

以上のように、本発明にかかる空気調和機用回転ロータは、製造時にロータに発生した反りを精度良く、かつ容易に矯正できるもので、家庭用、業務用の各種空気調和機は勿論、空気清浄機、換気装置などエアフィルターを有する各種機器に適用できるものである。   As described above, the rotary rotor for an air conditioner according to the present invention can accurately and easily correct the warp generated in the rotor at the time of manufacture. The present invention can be applied to various devices having an air filter such as a cleaner and a ventilator.
