Description

本発明は，空気調和機に関し，特に，吸い込みグリルの開度規制構造に関するものである。   The present invention relates to an air conditioner, and more particularly to an opening restriction structure of a suction grill.

従来の床置型空気調和機に備えられている吸い込みグリルには，吸い込んだ空気の異物を除くためのフィルターが備えられており，前記床置型空気調和機を稼動させることにより前記フィルターに異物が付着し空気の吸い込み機能を低下させる場合がある。そのため，前記フィルターの交換を行うことができるよう，前記吸い込みグリルは開閉自在とする必要がある。そのため，保守などで，前記床置型空気調和機の内部を点検できるように，前記吸い込みグリルを全開できるようにした床置型空気調和機が従来より存在する。しかしながら，前記吸い込みグリルを開閉自在とした場合，開口部から手を中に挿入し，前記床置型空気調和機の内部に備えられている送風機などの回転ファンに誤って手を巻き込まれるおそれがあった。
そのため，従来から，フィルターの交換は可能であるが手を内部に挿入することは不可能であるような半開きである第１の開放位置まで前記吸い込みグリルを開放できるよう開度を規制することができ，また，前記開度の規制を解除することにより前記第１の開放位置より大きく開放されたいわば全開の第２の開放位置まで前記吸い込みグリルを開放することが可能な床置型空気調和機が提案されている。
特許文献１に記載の床置型空気調和機では，筐体と吸い込みグリルとを連結し前記吸い込みグリルの開度を第１の開放位置で規制する開度規制部材が，Ｕ字状の部材で構成されている。前記筐体側に備えられた係止棒が，前記開度規制部材の上下の直線部に挟まれ，前記開度規制部材のＵ字部に当接することにより，前記開度規制部材は，前記吸い込みグリルを第１の開放位置まで開放することができる。また，前記開度規制部材の前記吸い込みグリル側の端部に取り付けられ，前記開度規制部材と前記吸い込みグリルとを固定するネジをはずすことにより前記開度の規制が解除され，前記吸い込みグリルを第２の開放位置まで開放することができる。
特許文献２に記載の床置型空気調和機では，開度規制部材は，筐体に設けられた係止孔に挿入され前記係止孔より大きい係止具が前記係止孔に当接することにより開度を規制する係止部と，吸い込みグリルに設けられ上端が開放された切欠孔が設けられた取り付け具とを有している。前記係止部の端部には，前記取り付け具に設けられた切欠孔と係合するネジが設けられている。前記切欠孔を挟み込み，ネジで固定すれば，前記開度規制部材は，前記吸い込みグリルを第１の開放位置まで開放することができる。前記切欠孔と係合するネジをゆるめ，前記取り付け具を前記係止部からはずすと，前記吸い込みグリルは第２の開放位置まで開放することができる。
特開２０００−８８２７８号公報 特開平１０−１４１６９８号公報 A suction grill provided in a conventional floor-mounted air conditioner is equipped with a filter for removing foreign matter from the sucked air. When the floor-mounted air conditioner is operated, foreign matter adheres to the filter. However, the air suction function may be reduced. Therefore, the suction grill needs to be openable and closable so that the filter can be replaced. Therefore, there is a floor-mounted air conditioner that can fully open the suction grill so that the inside of the floor-mounted air conditioner can be inspected for maintenance. However, when the suction grill is freely opened and closed, there is a risk that a hand is inserted into the opening and the hand is accidentally caught in a rotary fan such as a blower provided in the floor-mounted air conditioner. It was.
Therefore, conventionally, it is possible to regulate the opening degree so that the suction grille can be opened to the first open position that is half open so that the filter can be replaced but the hand cannot be inserted inside. And a floor-mounted air conditioner capable of opening the suction grille to a fully open second open position that is opened to a greater extent than the first open position by releasing the restriction of the opening degree. Proposed.

しかしながら，特許文献１に記載の空気調和機では，第２の開放位置まで前記吸い込みグリルを開放する際，前記開度規制部材と前記吸い込みグリルとが固定されている複数のネジのうち，１箇所のネジをはずすと，前記吸い込みグリルが前に倒れてきて，残りの固定されたネジをはずしにくいという問題があった。
一方，特許文献２に記載の空気調和機に設けられた開度規制部材では，前記吸い込みグリル開閉の際，前記開度規制部材本体が，前記筐体の前記係止孔を移動するので，前記係止孔の縁とこすれ，接触面積が大きいことから摩擦力が大きく，操作性が悪いという問題があった。
従って，本発明は前記事情に鑑みてなされたものであり，その目的とするところは，開度規制部材と吸い込みグリルとを固定するネジをはずしても前記吸い込みグリルが前に倒れてこないし，前記開度規制部材と前記吸い込みグリルを固定する位置がずれないので，前記吸い込みグリル開閉の際の操作性を向上し，また安全性にも配慮された空気調和機を提供することにある。 However, in the air conditioner described in Patent Document 1, when the suction grille is opened to the second open position, one of the plurality of screws to which the opening restriction member and the suction grille are fixed. When the screws were removed, the suction grill fell forward and there was a problem that it was difficult to remove the remaining fixed screws.
On the other hand, in the opening degree regulating member provided in the air conditioner described in Patent Document 2, when the suction grill is opened and closed, the opening degree regulating member body moves through the locking hole of the casing. There was a problem that the frictional force was large and the operability was poor because the contact area was rubbed and the contact area was large.
Therefore, the present invention has been made in view of the above circumstances, and the purpose of the present invention is that the suction grill does not fall forward even if the screw for fixing the opening restriction member and the suction grill is removed. An object of the present invention is to provide an air conditioner that improves the operability when opening and closing the suction grille, and also takes safety into consideration, because the position where the opening restriction member and the suction grille are fixed does not shift.

前記目的を達成するために本発明は，空気の吸い込み口が設けられた筐体と，前記筐体に設けられた吸い込み口から吸い込まれた異物を除くためのフィルターを備え，前記筐体の吸い込み口にその下端を支点として開閉自在に設けられた吸い込みグリルと，前記筐体と係合することにより前記筐体と前記吸い込みグリルとを連結し，前記吸い込みグリルが第１の開放位置までしか開かないよう前記筐体と前記吸い込みグリルとの開度を規制する開度規制部材とを含んでなり，前記連結を外すことにより前記規制が解除され，前記第１の開放位置より大きく開放された第２の開放位置まで前記吸い込みグリルを開放することが可能な空気調和機であって，
前記開度規制部材に係止孔又は係止突起が形成され，且つ前記吸い込みグリル上端に前記開度規制部材に形成された係止孔又は係止突起と係合することにより，前記開度規制部材が前記吸い込みグリルに係止する係止突起又は係止孔であって，前記吸い込みグリルの前記上端から前記下端に向かう方向の係止突起又は係止孔が形成され，前記開度規制部材の端部と，前記吸い込みグリルの上端近傍に前記開度規制部材と前記吸い込みグリルとをネジ固定するためのネジ孔であって，前記吸い込みグリルの前記上端から前記下端に向かう方向のネジ孔が設けられ，前記開度規制部材は，少なくともその本体と，該開度規制部材本体の前記筐体側端部に設けられ，該開度規制部材本体の横断面積より小さい断面形状からなるガイド突起とを備えてなり，更に前記筐体に，前記ガイド突起を案内する前記吸い込みグリルの開閉方向の長孔が形成され，前記ガイド突起が前記長孔の端部に当接することにより，前記吸い込みグリルの前記第１の開放位置における開度規制が行われてなることを特徴とする空気調和機として構成されている。
このように，前記開度規制部材に係止孔又は係止突起が形成され，且つ前記吸い込みグリルに前記開度規制部材に形成された係止孔又は係止突起と係合する係止突起又は係止孔が形成されることによって，前記開度規制部材と前記吸い込みグリルとをネジで固定する前に，前記係止孔に前記係止突起を係合させることにより，前記開度規制部材が前記吸い込みグリルに係止されるので，手で支えなくても，前記吸い込みグリルは前に倒れなくなり，前記開度規制部材と前記吸い込みグリルとを固定する位置がずれないので，前記ネジによる固定作業が極めて簡単となり，また安全性が向上する。
また，前記開度規制部材本体の前記筐体側端部に設けられたガイド突起の断面積は，前記開度規制部材本体の横断面積より小さいことにより，前記ガイド突起を前記筐体に形成された長孔に沿って摺動させたときの接触面積が小さいことから摩擦力が小さく，前記吸い込みグリル開閉の際の操作性が向上する。
さらに，前記開度規制部材が弾性部材であることが好ましい。
なぜなら，前記吸い込みグリルを開閉する際，前記開度規制部材を前記筐体に設けられた長孔に沿って摺動させる際に発生する衝撃を緩和し，スムーズに動かすことができるからである。更に，当該空気調和機が動作することにより発生する各部品の振動を吸収し，前記振動により各部品から発生する音を軽減する効果も期待される。
一方，前記開度規制部材は，前記吸い込みグリルに取り付けられる前記フィルターを略縦方向に案内する縦方向溝部を更に備えてなるものであることが考えられる。
このように，前記開度規制部材に，前記吸い込みグリルに取り付けられる前記フィルターを略縦方向に案内する縦方向溝部が形成されると，前記縦方向溝部に沿って前記フィルターを挿入するだけで前記フィルターを前記吸い込みグリルに取り付けることができ，前記フィルターの取り付け作業が容易になる。
また，当該空気調和機が床置型であることが考えられる。
床置型空気調和機の場合，利用者の手が届き易い位置にあるため，開口部から手を中に挿入し，前記床置型空気調和機の内部に備えられている送風機などの回転ファンに誤って手を巻き込まれることがないよう，利用者がフィルターを交換する際には，前記開度規制部材により第１の開放位置までしか前記吸い込みグリルを開放できない構成にして，安全性を高める必要がある。 To accomplish the above object, comprises a housing suction port of the air is provided, a filter for removing foreign substances sucked from the suction port provided in the housing, the suction of the housing A suction grill provided at the mouth with its lower end as a fulcrum is connected to the housing, and the housing and the suction grill are connected by engaging with the housing, and the suction grill opens only to the first open position. An opening restriction member for restricting the opening of the housing and the suction grill so that the restriction is released by releasing the connection, and the opening is larger than the first opening position. An air conditioner capable of opening the suction grille to an open position of 2,
Said locking hole or locking projection to the opening degree limiting member is formed, and by engaging the locking hole or locking projection formed on the opening regulating member to the inlet grill upper, the opening regulating A member is a locking projection or a locking hole for locking to the suction grille, and a locking projection or a locking hole in a direction from the upper end to the lower end of the suction grille is formed . A screw hole for screwing the opening degree restricting member and the suction grille near the upper end of the suction grille, and a screw hole extending in a direction from the upper end to the lower end of the suction grille. The opening restriction member includes at least a main body thereof, and a guide protrusion provided at an end of the opening restriction member main body on the housing side and having a cross-sectional shape smaller than a cross-sectional area of the opening restriction member main body. The Further, a long hole in the opening / closing direction of the suction grill for guiding the guide protrusion is formed in the housing, and the guide protrusion abuts on an end of the long hole, whereby the first of the suction grill is formed. It is configured as an air conditioner characterized in that opening degree regulation at the open position is performed .
As in this, the locking holes or the locking projection to the opening degree limiting member is formed, and the suction locking projection to the opening regulating member engaging holes or engaging projections engage formed in the grill Alternatively, the opening restriction member is formed by engaging the engagement protrusion with the engagement hole before the opening restriction member and the suction grille are fixed with screws by forming the engagement hole. Is locked to the suction grille, so that even if it is not supported by the hand, the suction grille will not fall forward and the position where the opening restricting member and the suction grille are fixed will not be displaced. Work becomes extremely easy and safety is improved.
In addition, the guide protrusion is formed on the casing because the cross-sectional area of the guide protrusion provided on the casing-side end of the opening restriction member main body is smaller than the cross-sectional area of the opening restriction member main body. Since the contact area when sliding along the long hole is small, the frictional force is small and the operability when opening and closing the suction grill is improved.
Further, the opening degree regulating member is preferably an elastic member.
This is because, when opening and closing the suction grille, it is possible to reduce the impact generated when the opening degree restricting member is slid along the long hole provided in the housing, and to move smoothly. Furthermore, the effect of absorbing the vibration of each component generated by the operation of the air conditioner and reducing the sound generated from each component due to the vibration is also expected.
On the other hand, it is conceivable that the opening degree regulating member further includes a longitudinal groove portion that guides the filter attached to the suction grille in a substantially longitudinal direction.
As described above, when the longitudinal groove portion for guiding the filter attached to the suction grille in the substantially vertical direction is formed on the opening degree regulating member, the filter is simply inserted along the longitudinal groove portion. A filter can be attached to the suction grille, and the filter can be easily attached.
Moreover, it is possible that the said air conditioner is a floor type.
In the case of a floor-mounted air conditioner, the user's hand is easily reachable. Therefore, a hand is inserted through the opening, and a rotary fan such as a blower provided inside the floor-mounted air conditioner is erroneously inserted. Therefore, when the user replaces the filter, the suction grill must be opened only to the first open position by the opening degree regulating member so that the hand is not caught. is there.

本発明に係る空気調和機によれば，開度規制部材と吸い込みグリルとを固定するネジをはずしても前記吸い込みグリルが前に倒れてこないし，前記開度規制部材と前記吸い込みグリルを固定する位置がずれないので，前記吸い込みグリル開閉の際の操作性が向上する。   According to the air conditioner of the present invention, the suction grill does not fall forward even if the screw for fixing the opening restriction member and the suction grill is removed, and the opening restriction member and the suction grill are fixed. Since the position does not shift, the operability when opening and closing the suction grill is improved.

図５に示すように，前記開度規制部材１０には，前記吸い込みグリル４側の端部に，前記吸い込みグリル４に形成された係止突起Ｅと係合する係止孔Ｄが形成されている。また，前記開度規制部材１０は，この開度規制部材１０の本体部分を構成する開度規制部材本体１０Ａと，該開度規制部材本体１０Ａの前記筐体２側の端部に形成され，該開度規制部材本体１０Ａの横断面積よりも小さい断面形状からなるガイド突起１０Ｂとを備えて構成されている。前記ガイド突起１０Ｂは，立上部１０Ｂ１と，突起部１０Ｂ２とを備えて構成されている。前記開度規制部材本体１０Ａには，前記係止孔Ｄと前記ガイド突起１０Ｂとの間に平面視で略Ｚ形状の溝部１０Ａ１が形成されている。前記溝部１０Ａ１は，前記吸い込みグリル４に取り付けられる前記フィルター３を略縦方向（図５におけるＰ５方向）に案内する。
開度規制部材は図３に示すように左右に１対（１０，１１）設けられており，図６に示す開度規制部材１１は，前記開度規制部材１０と同様の構造であり，前記開度規制部材１０と左右対称となっている。
このように，前記開度規制部材１０，１１に，前記吸い込みグリル４に取り付けられる前記フィルター３を略縦方向に案内する縦方向溝部１０Ａ１，１１Ａ１が形成されることにより，前記縦方向溝部１０Ａ１，１１Ａ１に沿って図５，図６におけるＰ５方向に前記フィルター３を挿入するだけで，前記フィルター３を前記吸い込みグリル４に取り付けることができ，前記フィルター３の取り付け作業が容易になる。
前記開度規制部材１０，１１は，樹脂などの弾性部材で構成することができる。
前記開度規制部材１０，１１を弾性部材で構成することで，前記吸い込みグリル４を開閉する際，前記開度規制部材１０，１１を前記開度規制部材案内板１２，１３に形成された長孔Ｆに沿って摺動させる際に発生する衝撃を緩和し，スムーズに動かすことができる。更に，当該空気調和機Ｘが動作することにより発生する各部品の振動を吸収し，前記振動により各部品から発生する音を軽減する効果も奏されよう。 The opening restriction members 10 and 11 will be described with reference to FIGS.
As shown in FIG. 5, the opening restriction member 10 is formed with a locking hole D that engages with a locking projection E formed on the suction grill 4 at the end of the suction grill 4. Yes. The opening restriction member 10 is formed at an opening restriction member main body 10A constituting the main body portion of the opening restriction member 10 and an end of the opening restriction member main body 10A on the casing 2 side. A guide protrusion 10B having a cross-sectional shape smaller than the cross-sectional area of the opening degree regulating member main body 10A is provided. The guide projection 10B includes an upright portion 10B1 and a projection portion 10B2. In the opening degree regulating member main body 10A, a substantially Z-shaped groove portion 10A1 is formed between the locking hole D and the guide projection 10B in a plan view. The groove portion 10A1 guides the filter 3 attached to the suction grill 4 in a substantially vertical direction (P5 direction in FIG. 5).
As shown in FIG. 3, the pair of opening restriction members (10, 11) is provided on the left and right, and the opening restriction member 11 shown in FIG. 6 has the same structure as the opening restriction member 10. It is symmetrical with the opening degree regulating member 10.
As described above, the opening restriction members 10 and 11 are formed with the longitudinal groove portions 10A1 and 11A1 for guiding the filter 3 attached to the suction grille 4 in the substantially longitudinal direction, whereby the longitudinal groove portions 10A1 and 10A1 are formed. The filter 3 can be attached to the suction grille 4 simply by inserting the filter 3 in the direction P5 in FIGS. 5 and 6 along the line 11A1, and the attachment work of the filter 3 becomes easy.
The opening restriction members 10 and 11 can be formed of an elastic member such as resin.
By configuring the opening restriction members 10 and 11 with elastic members, the opening restriction members 10 and 11 are formed on the opening restriction member guide plates 12 and 13 when the suction grill 4 is opened and closed. The impact generated when sliding along the hole F can be mitigated and moved smoothly. Furthermore, the vibration of each component generated by the operation of the air conditioner X will be absorbed, and the effect of reducing the sound generated from each component by the vibration will also be achieved.

図７を用いて前記開度規制部材案内板１２について説明する。前記開度規制部材案内板１２は前記筐体２側に固定される部材であり，前記吸い込みグリル４の開閉方向（図７におけるＰ１，Ｐ２方向）に長い長孔Ｆが形成されている。前記長孔Ｆには，前記開度規制部材１０に形成された前記ガイド突起１０Ｂが嵌入係合されている。従って，前記開度規制部材１０は，前記ガイド突起１０Ｂを介して前記開度規制部材案内板１２に形成された長孔Ｆに沿って摺動させることができる。前記長孔Ｆの前記吸い込みグリル４側の縁１２Ａまで図７におけるＰ１方向に前記開度規制部材１０を摺動させると，前記開度規制部材１０のガイド突起１０Ｂに形成された立上部１０Ｂ１が縁１２Ａに当接し，前記開度規制部材１０はそれ以上前記吸い込みグリル４側略水平方向（図７におけるＰ１方向）へ摺動させることはできない。これにより，前記吸い込みグリル４が第１の開閉位置で保持され，その位置で開度が規制される。
また，前記突起部１０Ｂ２の幅は，前記吸い込みグリル４側の端部における長孔Ｆの幅より大きいので，前記開度規制部材１０に形成されたガイド突起１０Ｂと前記長孔Ｆとの嵌入係合がはずれることはない。
前記開度規制部材１１についても，図８に示すように前記開度規制部材案内板１３と係合する。
図７，図８に示すように，前記開度規制部材１０，１１に形成されたガイド突起１０Ｂ，１１Ｂの断面積は，前記開度規制部材本体１０Ａ，１１Ａの横断面積より小さいことにより，前記開度規制部材本体１０Ａ，１１Ａを，前記開度規制部材案内板１２，１３に形成された長孔Ｆに沿って摺動させるよりも，接触面積が小さいことから摩擦力が小さく，前記吸い込みグリル４開閉の際の操作性が向上する。 The opening degree restricting member guide plate 12 will be described with reference to FIG. The opening degree restricting member guide plate 12 is a member fixed to the housing 2 side, and a long slot F is formed in the opening / closing direction of the suction grill 4 (P1, P2 direction in FIG. 7). In the long hole F, the guide protrusion 10B formed on the opening degree restricting member 10 is fitted and engaged. Accordingly, the opening degree regulating member 10 can be slid along the long hole F formed in the opening degree regulating member guide plate 12 via the guide protrusion 10B. When the opening restriction member 10 is slid in the direction P1 in FIG. 7 to the edge 12A on the suction grille 4 side of the long hole F, an upright portion 10B1 formed on the guide protrusion 10B of the opening restriction member 10 is formed. Abutting on the edge 12A, the opening restriction member 10 cannot be slid further in the substantially horizontal direction (P1 direction in FIG. 7) on the suction grill 4 side. Accordingly, the suction grill 4 is held at the first opening / closing position, and the opening degree is regulated at the position.
Further, since the width of the protrusion 10B2 is larger than the width of the long hole F at the end on the suction grill 4 side, the insertion protrusion between the guide protrusion 10B formed on the opening restriction member 10 and the long hole F is provided. There is no losing luck.
The opening restriction member 11 is also engaged with the opening restriction member guide plate 13 as shown in FIG.
As shown in FIGS. 7 and 8, the sectional area of the guide protrusions 10B and 11B formed on the opening restriction members 10 and 11 is smaller than the cross-sectional area of the opening restriction member bodies 10A and 11A. Since the contact area is smaller than when the opening restriction member bodies 10A and 11A are slid along the long holes F formed in the opening restriction member guide plates 12 and 13, the suction grille is small. 4. Operability when opening and closing is improved.

前記筐体２と前記吸い込みグリル４との開度について説明する。
図３において前記吸い込みグリル４が閉じた状態の位置をＡとし，初期状態とする。前記固定つまみ５をはずすと，前記吸い込みグリル４の両端上方に備えられた前記開度規制部材１０，１１の規制により，前記吸い込みグリル４は図３における位置Ａから第１の開放位置である位置Ｂまで，前記固定された下端を開閉の支点として，わずかに開放することができる。
このとき，図５に示すように前記開度規制部材１０に形成された係止孔Ｄと前記吸い込みグリル４に形成された係止突起Ｅとが係合し，更にネジ孔Ｇにおいてネジで固定することにより，前記開度規制部材１０と前記吸い込みグリル４とが連結固定されている。
前記開度規制部材１１についても同様である。
従って，前記開度規制部材１０，１１を前記吸い込みグリル４からはずして前記吸い込みグリル４を第２の開放位置まで開くに際して，ネジ孔Ｇに螺着したネジをはずしても，前記係止孔Ｄと前記係止突起Ｅとが係合しているのでこの状態で手を離しても前記吸い込みグリル４が倒れたりする不都合がなく，作業者の操作性が向上する。また作業が安全である。こうして作業の安全性が確保された状態で，前記係止孔Ｄと前記係止突起Ｅの係合を解除して前記吸い込みグリル４を前記第１の開放位置より大きく開かれた第２の開放位置である図４における位置Ｃまで，前記固定された下端を開閉の支点として，Ｐ３方向に開放することができる。 The opening degree of the housing 2 and the suction grill 4 will be described.
In FIG. 3, the position where the suction grille 4 is closed is A, and is the initial state. When the fixing knob 5 is removed, the suction grill 4 is located at the first open position from the position A in FIG. 3 due to the restriction of the opening restriction members 10 and 11 provided above both ends of the suction grill 4. Up to B, the fixed lower end can be opened slightly using the opening / closing fulcrum.
At this time, as shown in FIG. 5, the engagement hole D formed in the opening degree restricting member 10 and the engagement protrusion E formed in the suction grill 4 are engaged, and the screw hole G is fixed with screws. Thus, the opening degree regulating member 10 and the suction grill 4 are connected and fixed.
The same applies to the opening degree regulating member 11.
Accordingly, when the opening restricting members 10 and 11 are removed from the suction grill 4 and the suction grill 4 is opened to the second open position, the locking hole D can be removed even if the screw screwed into the screw hole G is removed. Since the engagement protrusion E is engaged, there is no inconvenience that the suction grill 4 falls down even if the hand is released in this state, and the operability for the operator is improved. Work is safe. Thus, in a state where the safety of the work is ensured, the engagement between the engagement hole D and the engagement protrusion E is released, and the suction grill 4 is opened larger than the first release position. Up to the position C in FIG. 4 which is the position, the fixed lower end can be opened in the P3 direction using the opening / closing fulcrum.

前記吸い込みグリル４を閉める場合について説明する。
前記開度規制部材１０，１１と前記吸い込みグリル４とをネジ孔Ｇにおいて固定するネジがはずされ図４における位置Ｃまで開放された前記吸い込みグリル４は，前記固定された下端を開閉の支点として，Ｐ４方向に閉められ，図３における位置Ｂで前記開度規制部材１０，１１に形成されている係止孔Ｄと，前記吸い込みグリル４に形成されている係止突起Ｅを係合させることにより，前記開度規制部材１０，１１が前記吸い込みグリル４に係止される。
このように，前記開度規制部材１０，１１に係止孔Ｄが形成され，且つ前記吸い込みグリル４に前記開度規制部材１０，１１に形成された係止孔Ｄと係合する係止突起Ｅが形成されることによって，前記開度規制部材１０，１１と前記吸い込みグリル４とをネジ孔Ｇにおいてネジで固定する前に，前記係止孔Ｄに前記係止突起Ｅを係合させることにより，前記開度規制部材１０，１１が前記吸い込みグリル４に係止されるので，作業者が手で支えなくても前記吸い込みグリル４は前に倒れなくなり，両手でネジによる固定作業を行うことが可能となり，作業者の操作性が向上する。また，作業の安全が確保される。更に，前記開度規制部材１０，１１と前記吸い込みグリル４とを固定する位置がずれないので，極めて簡単にネジによる固定作業を行うことができる。
このように，作業者は，前記開度規制部材１０，１１と前記吸い込みグリル４とが係止した状態で，すなわち作業の安全性が確保された状態で，前記開度規制部材１０，１１と前記吸い込みグリル４に備えられたネジ孔Ｇにおいて，前記開度規制部材１０，１１と前記吸い込みグリル４とをネジで固定する。続いて前記吸い込みグリル４は，前記固定された下端を開閉の支点として，図４におけるＰ４方向に閉じられる。前記吸い込みグリル４は，図３における位置Ａで完全に閉まる。
なお，ここでは，前記開度規制部材１０，１１に係止孔Ｄ，前記吸い込みグリル４に係止突起Ｅが形成されているが，前記開度規制部材１０，１１に係止突起を形成し，前記開度規制部材１０，１１に形成された係止突起と係合する係止孔を前記吸い込みグリル４に形成する構成でもかまわない。
また，前記開度規制部材１０，１１に形成された係止孔Ｄのかわりに，前記吸い込みグリル４に形成された係止突起Ｅと係合するくぼみを前記開度規制部材１０，１１に形成する構成でもかまわない。 A case where the suction grill 4 is closed will be described.
The suction grille 4 that is opened to the position C in FIG. 4 by removing the screws that fix the opening restriction members 10 and 11 and the suction grille 4 in the screw holes G has the fixed lower end as an opening / closing fulcrum. , P4, and the engagement protrusion D formed in the suction grille 4 is engaged with the engagement hole D formed in the opening restriction members 10 and 11 at the position B in FIG. As a result, the opening restriction members 10 and 11 are locked to the suction grill 4.
Thus, the locking holes D are formed in the opening restriction members 10 and 11, and the locking protrusions that engage with the locking holes D formed in the opening restriction members 10 and 11 in the suction grill 4. By forming E, before the opening restricting members 10 and 11 and the suction grill 4 are fixed with screws in the screw holes G, the locking protrusions E are engaged with the locking holes D. Thus, since the opening restricting members 10 and 11 are locked to the suction grill 4, the suction grill 4 does not fall forward even if the operator does not support it with his hand, and the fixing work with screws is performed with both hands. This improves the operability for the operator. In addition, work safety is ensured. Furthermore, since the position where the opening degree regulating members 10 and 11 and the suction grill 4 are fixed does not shift, the fixing operation with screws can be performed very easily.
In this way, the operator can move the opening degree regulating members 10 and 11 in a state where the opening degree regulating members 10 and 11 and the suction grill 4 are locked, that is, in a state where work safety is ensured. In the screw holes G provided in the suction grill 4, the opening restriction members 10 and 11 and the suction grill 4 are fixed with screws. Subsequently, the suction grill 4 is closed in the direction P4 in FIG. 4 using the fixed lower end as a fulcrum for opening and closing. The suction grill 4 is completely closed at position A in FIG.
Here, the opening restricting members 10 and 11 are formed with a locking hole D and the suction grille 4 is formed with a locking protrusion E. However, the opening restricting members 10 and 11 are formed with a locking protrusion. The suction grill 4 may be formed with a locking hole that engages with a locking projection formed on the opening restriction members 10 and 11.
Further, in place of the locking holes D formed in the opening restriction members 10, 11, recesses that engage with the locking protrusions E formed in the suction grill 4 are formed in the opening restriction members 10, 11. It does not matter if it is configured to do so.

また，当該空気調和機Ｘは吸い込みグリルが大型の床置型に適用して好適であるが，もちろんそれ以外の形式の空気調和機に適用してもかまわない。
当該空気調和機Ｘが床置型空気調和機の場合，床置型でない空気調和機と比べて機器は利用者の手が届き易い位置にあるため，前記吸い込み口１などの開口部から手を中に挿入し，前記床置型空気調和機の内部に備えられている送風機６などの回転ファンに誤って手を巻き込まれることがないよう，利用者がフィルター３を交換する際には，前記開度規制部材１０，１１により第１の開放位置までしか前記吸い込みグリル４を開放できない本発明に係る実施の形態のような構成にすれば，安全性を高めることができる。 In addition, the air conditioner X is suitable for application to a floor type with a large suction grille, but of course, it may be applied to other types of air conditioners.
In the case where the air conditioner X is a floor-mounted air conditioner, the device is more easily reachable by the user than a non-floored air conditioner. When the user replaces the filter 3 so that the hand is not accidentally caught in a rotary fan such as the blower 6 provided inside the floor-mounted air conditioner, the opening degree restriction Safety can be improved by adopting the configuration according to the embodiment of the present invention in which the suction grill 4 can be opened only by the members 10 and 11 to the first open position.
