Description

本発明は、吹出口に、吹き出される空気の向きを調整するベーンが設けられた空気調和機に関する。   The present invention relates to an air conditioner in which a vane that adjusts the direction of air to be blown out is provided at an air outlet.

一般的に、空気調和機は、吸込口および吹出口が形成され、内部にファンが収容された筐体を備えており、筐体には、吹出口から吹出される空気の向きを調整するためのベーン(風向板)が設けられている。従来の空気調和機では、一般ユーザーが素手で吹出口からベーンを容易に取り外せるようになっていた。そのため、ベーンが取り外された状態で空気調和機を運転させることがあり、その場合には、運転中に誤って筐体内部のファンに指を接触させてしまうという可能性が存在していた。それを防止するため、一般ユーザーが素手では吹出口からベーンを容易に取り外しできない機構とする必要があった。そのような背景から、素手ではベーンを容易に取り外すことができないが、例えばドライバーなどの一般的な軸状工具を用いることで、ベーンの取り外しができる空気調和機が提案されている（例えば、特許文献１参照）。   In general, an air conditioner has a housing in which a suction port and a blow-out port are formed and a fan is accommodated therein, and the housing is for adjusting the direction of air blown from the blow-out port. Vanes (wind direction plates) are provided. In a conventional air conditioner, a general user can easily remove a vane from a blowout port with bare hands. Therefore, the air conditioner may be operated in a state where the vane is removed. In this case, there is a possibility that a finger is accidentally brought into contact with the fan inside the casing during the operation. In order to prevent this, it was necessary for a general user to have a mechanism in which the vane cannot be easily removed from the air outlet with bare hands. From such a background, an air conditioner that can remove a vane by using a general shaft-like tool such as a screwdriver has been proposed (for example, a patent). Reference 1).

この従来の空気調和機は、ベーンの中間部が支持軸構造によって回転自在に支持されている。支持軸構造は、ベーンに取り付けられるベース板と、ベース板に突設された軸サポート片と、軸サポート片に設けられた軸と、筐体に設けられ、軸を回転自在に支持する軸受部と、ベーンに突設されてベース板を摺動できるように支持する爪部と、ベース板の両側縁部に張り出すように突設された係止片と、ベーンに設けられたカバー部とを備えている。そして、係止片が爪部に接触することで、軸が抜け出ることを防止し、カバー部が軸サポート片を覆うものであった。   In this conventional air conditioner, the intermediate portion of the vane is rotatably supported by the support shaft structure. The support shaft structure includes a base plate attached to the vane, a shaft support piece projecting from the base plate, a shaft provided on the shaft support piece, and a bearing portion provided on the housing for rotatably supporting the shaft. A claw portion that protrudes from the vane and supports the base plate so as to be slidable, a locking piece that protrudes from both side edges of the base plate, and a cover portion that is provided on the vane It has. And when a locking piece contacted the nail | claw part, it prevented that the axis | shaft slipped out and the cover part covered the axis | shaft support piece.

特許文献１に記載の技術によれば、ベーンを取り外す作業において、支持軸構造のベース板の両側縁部に張り出して形成されている係止部とベーン背面上に突設された各爪部との係合を、それぞれ解除する必要がある。この作業は、素手で行うことができないため、素手で吹出口からベーンを容易には取り外せず、使用者が、意図せずにベーンが外れることを防止できた。
しかしながら、工具を用いてベーンを取り外す際には、ベース板の両側縁部に軸の挿抜方向に直交する方向に張り出している両係止部と両爪部との係合を解いて、中間支持軸体を軸線に沿って軸を抜く方向へ摺動させる必要がある。そのため、両係止部と両爪部との係合を、両側からそれぞれ工具を使用して同時に解除する（両爪部間の間隔を広げる）必要があり、サービス業者にとってもベーンを取り外す際の作業性が悪かった。そのため、メンテナンス性の改善が望まれていた。 According to the technique described in Patent Document 1, in the work of removing the vane, the locking portions that are formed to protrude from both side edges of the base plate of the support shaft structure, and the respective claw portions that protrude from the back surface of the vane, It is necessary to release the respective engagements. Since this operation cannot be performed with bare hands, the vane cannot be easily removed from the outlet with bare hands, and the user can prevent the vane from being unintentionally removed.
However, when removing the vane using a tool, disengage both the locking parts and the claws that protrude in the direction perpendicular to the shaft insertion / removal direction on both side edges of the base plate, It is necessary to slide the shaft body along the axis in the direction of removing the shaft. Therefore, it is necessary to simultaneously release the engagement between both locking parts and both claw parts from both sides by using a tool (increase the distance between both claw parts). Workability was bad. Therefore, improvement in maintainability has been desired.

本発明は、前記のような課題を解決するためになされたもので、素手では吹出口からベーンを容易に取り外せないが、一般的な軸状工具を用いることで、容易にベーンを取り外すことができる空気調和機を提供することを目的とする。   The present invention has been made to solve the above-described problems, and the vane cannot be easily removed from the blow outlet with a bare hand, but the vane can be easily removed by using a general shaft-shaped tool.

図４のように中間支持軸体３０が中間支持軸体取付部４０に取り付けられた際、中間支持軸体３０は、先端側の軸サポート片３３が中間支持軸体取付部４０の軸差込部４３に突き当たり、また図９（ｂ）のように基台３２から延びて下方へと傾斜した後端側の爪３６が係止突起４４に突き当たるので、長手方向に摺動できない。また、その際、爪３６と係止突起４４との接触部は、ガード部３７にて覆われている。ガード部３７の長手方向の側面部には切欠き３８ａ，３８ｂが設けられているので、側面から見ると、爪３６と係止突起４４との接触部が確認できる。この切欠き３８ａ，３８ｂすなわちガード部３７とベーン４の背面との隙間は、マイナスドライバーのような一般的な軸状工具を差し込むことができる大きさである。また、切欠き３８ｃで形成される隙間は、係止突起４４が通過できる大きさである。   As shown in FIG. 4, when the intermediate support shaft body 30 is attached to the intermediate support shaft body attachment portion 40, the intermediate support shaft body 30 has the shaft support piece 33 on the distal end side inserted into the shaft of the intermediate support shaft body attachment portion 40. The claw 36 on the rear end side that abuts against the portion 43 and extends from the base 32 and inclines downward as shown in FIG. 9B abuts against the locking projection 44 and cannot slide in the longitudinal direction. At this time, the contact portion between the claw 36 and the locking projection 44 is covered with a guard portion 37. Since the notches 38a and 38b are provided in the side surface in the longitudinal direction of the guard portion 37, the contact portion between the claw 36 and the locking projection 44 can be confirmed when viewed from the side. The gaps between the notches 38a and 38b, that is, the guard portion 37 and the rear surface of the vane 4 are large enough to insert a general shaft-like tool such as a flat-blade screwdriver. Moreover, the clearance gap formed by the notch 38c is a magnitude | size which the latching protrusion 44 can pass.

前記のように構成された室内機１００においては、ベーン２、ベーン３、およびベーン４の取り付け、取り外しが行われる。なお、ベーン２、ベーン３、およびベーン４の取り付け、取り外し方法は、同様であるため、ここではベーン４の場合を例に挙げて説明する。 (Vane installation and removal method)
Next, the procedure for attaching and removing the vanes will be described with reference to FIGS.
10A and 10B show the support shaft structure 20 before being assembled with the shaft rotating portion 50 of the indoor unit 100 that is an air conditioner according to an embodiment of the present invention. FIG. 10A is a plan view, and FIG. It is SS sectional view taken on the line of (). FIG. 11 shows the support shaft structure 20 in a state assembled with the shaft rotating portion 50 of the air conditioner according to the embodiment of the present invention, where (a) is a plan view and (b) is an R- of this (a). It is R arrow sectional drawing. FIGS. 12A and 12B show the support shaft structure 20 in a state of being axially connected to the shaft rotating portion 50 of the air conditioner according to the embodiment of the present invention. FIG. 12A is a plan view, and FIG. It is QQ arrow sectional drawing. FIG. 13 shows the support shaft structure 20 in a state where it is axially connected to the shaft rotating portion 50 of the air conditioner according to the embodiment of the present invention and the claw 36 and the locking projection 44 are engaged. ) Is a plan view, and (b) is a cross-sectional view taken along the line PP of (a).
In the indoor unit 100 configured as described above, the vane 2, the vane 3, and the vane 4 are attached and detached. In addition, since the attachment method of the vane 2, the vane 3, and the vane 4 is the same, the case of the vane 4 will be described as an example here.

（ベーンの取り付け方法）
ベーン４を取り付けるには、始めに、図１０（ａ）のように、中間支持軸体３０をストッパー３５と保持部４１が接触する位置までガイド４２に沿って摺動させる。このとき、図１０（ｂ）のように、爪３６は係止突起４４を乗り越えた位置にある。次に、ベーン４を移動させ、図１１（ａ）（ｂ）のように、軸回転部５０が軸差込部４３の真横の位置にくるようにする。続いて、図１２（ａ）のように、中間支持軸体３０を軸３４が軸差込部４３から軸回転部５０の軸受部５１に挿入される方向(図１２では左方向)へと摺動させ、軸３４を軸回転部５０の軸受部５１に挿入させる。このとき、図１２（ｂ）のように、爪３６は、係止突起４４を乗り越え、図９、および図１３（ａ）（ｂ）のように、爪３６と係止突起４４とが軸３４の軸線方向で対向するように接触する。また、先端側の軸サポート片３３が中間支持軸体取付部４０の軸差込部４３に突き当たる。このため、中間支持軸体３０は摺動できなくなる。このとき、爪３６と係止突起４４の接触部は、ガード部３７の内側に位置する。以上の流れでベーン４は、筐体１に取り付けられる。 (Vane installation method)
To attach the vane 4, first, as shown in FIG. 10A, the intermediate support shaft body 30 is slid along the guide 42 to a position where the stopper 35 and the holding portion 41 are in contact with each other. At this time, as shown in FIG. 10B, the claw 36 is in a position over the locking projection 44. Next, the vane 4 is moved so that the shaft rotating portion 50 is located at a position directly beside the shaft inserting portion 43 as shown in FIGS. Subsequently, as shown in FIG. 12A, the intermediate support shaft 30 is slid in the direction in which the shaft 34 is inserted from the shaft insertion portion 43 into the bearing portion 51 of the shaft rotating portion 50 (leftward in FIG. 12). The shaft 34 is inserted into the bearing portion 51 of the shaft rotating portion 50. At this time, as shown in FIG. 12B, the claw 36 gets over the locking projection 44, and the claw 36 and the locking projection 44 are connected to the shaft 34 as shown in FIG. It contacts so that it may oppose in the direction of an axis. Further, the shaft support piece 33 on the distal end side abuts against the shaft insertion portion 43 of the intermediate support shaft body mounting portion 40. For this reason, the intermediate support shaft 30 cannot slide. At this time, the contact portion between the claw 36 and the locking projection 44 is located inside the guard portion 37. The vane 4 is attached to the housing 1 by the above flow.

（ベーンの取り外し方法）
ベーン４を取り外すには、ベーン４を取り付け方法と逆の流れをとる。つまり、中間支持軸体３０を軸３４が軸回転部５０の軸受部５１に挿入される方向とは逆向きに摺動させる。その際、爪３６を、上方に押し上げ、中間支持軸体取付部４０の係止突起４４を乗り越えさせる必要がある。しかし、ベーン４が吹出口１ｂに取り付けられている状態では、爪３６と係止突起４４との接触部がガード部３７にて覆われていて、爪３６がガード部３７の内側に位置するため、素手で（つまり、工具を用いずに）爪３６と係止突起４４の係合を解除することはできない。したがって、素手では吹出口１ｂからベーン４を取り外すことはできない。 (How to remove the vane)
In order to remove the vane 4, the flow reverse to the method of attaching the vane 4 is taken. That is, the intermediate support shaft 30 is slid in the direction opposite to the direction in which the shaft 34 is inserted into the bearing portion 51 of the shaft rotating portion 50. At that time, it is necessary to push up the claw 36 upward to get over the locking projection 44 of the intermediate support shaft mounting portion 40. However, when the vane 4 is attached to the air outlet 1b, the contact portion between the claw 36 and the locking projection 44 is covered with the guard portion 37, and the claw 36 is located inside the guard portion 37. The engagement between the claw 36 and the locking projection 44 cannot be released with bare hands (that is, without using a tool). Therefore, the vane 4 cannot be removed from the outlet 1b with bare hands.

そこで、支持軸構造２０では、マイナスドライバーのような一般的な軸状工具を用いて、爪３６と係止突起４４の係合を容易に解除することができるようにしている。つまり、室内機１００は、マイナスドライバーのような一般的な軸状工具を用いて、ベーン４を容易に取り外すことができる。例えば、マイナスドライバーをガード部３７の切欠き３８ａ又は３８ｂに挿入し、爪２６を押し上げ（図１２の状態）、その状態で中間支持軸体３０を後方へ摺動させ、係止突起４４を乗り越えさせる。爪２６が係止突起４４を乗り越えれば、中間支持軸体３０を軸３４が挿入される方向とは逆方向にスムースに摺動させることができるようになり、軸３４を軸回転部５０の軸受部５１から抜き出すことができる（図１１の状態）。したがって、サービス業者が室内機１００のメンテナンスを行う場合、マイナスドライバー等の一般的な軸状工具を用いて、ベーン４を容易に吹出口１ｂから取り外すことができる（つまり、メンテナンスにおける作業性が良い）。   Therefore, in the support shaft structure 20, the engagement between the claw 36 and the locking projection 44 can be easily released using a general shaft tool such as a flat-blade screwdriver. That is, the indoor unit 100 can easily remove the vane 4 using a general shaft tool such as a flat-blade screwdriver. For example, a flathead screwdriver is inserted into the notch 38a or 38b of the guard portion 37, the claw 26 is pushed up (the state shown in FIG. 12), and the intermediate support shaft 30 is slid rearward in this state to overcome the locking projection 44. Let If the claw 26 gets over the locking projection 44, the intermediate support shaft 30 can be smoothly slid in the direction opposite to the direction in which the shaft 34 is inserted. It can be extracted from the part 51 (state of FIG. 11). Therefore, when the service provider performs maintenance of the indoor unit 100, the vane 4 can be easily removed from the outlet 1b using a general shaft tool such as a flat-blade screwdriver (that is, workability in maintenance is good). ).

以上のように構成された室内機１００においては、素手では吹出口１ｂからベーン２、ベーン３、およびベーン４を容易に取り外すことはできないが、一般的な軸状工具を用いることで、容易にベーン２、ベーン３、およびベーン４を取り外すことができる室内機１００を得ることができる。その際、切欠き３８ａまたは切欠き３８ｂから挿入された軸状工具によって爪３６が上方向に移動させられて係止突起４４を乗り越えることができるとともに、爪３６が設けられている基台３２はガイド４２に案内されるベース板３１が保持部４１によって保持されているので、軸３４と軸受部５１との芯ズレが起こらず、芯ズレを考慮する必要がなく、作業性が向上する。そのため、一般ユーザーが誤ってベーンを外してしまうことがなく、サービス業者がメンテナンス時に作業性良くベーンの取り外しを行うことができる。 In the indoor unit 100 configured as described above, the vane 2, the vane 3, and the vane 4 cannot be easily removed from the outlet 1b with bare hands, but can be easily performed by using a general shaft tool. The indoor unit 100 from which the vane 2, the vane 3, and the vane 4 can be removed can be obtained. At that time, the claw 36 can be moved upward by the shaft-shaped tool inserted from the notch 38a or the notch 38b to get over the locking projection 44, and the base 32 on which the claw 36 is provided is Since the base plate 31 guided by the guide 42 is held by the holding portion 41, there is no misalignment between the shaft 34 and the bearing portion 51, and there is no need to consider the misalignment, and workability is improved. Therefore, the general user does not accidentally remove the vane, and the service provider can remove the vane with good workability during maintenance.

なお、前述の実施形態では、本発明を室内機と室外機とを有するセパレートタイプの空気調和機に用いたものを例に挙げて説明したが、これに限るものでなく、一体型の空気調和機にも本発明を適用できることは言うまでもない。   In the above-described embodiment, the present invention has been described with reference to an example in which the present invention is used for a separate type air conditioner having an indoor unit and an outdoor unit. However, the present invention is not limited to this, and is an integrated air conditioner. Needless to say, the present invention can also be applied to a machine.
