Description

本発明は空気調和機に関し、特にケーシングに係るものである。   The present invention relates to an air conditioner, and particularly relates to a casing.

従来、この種の空気調和機では、一般的な構造として構造材をなすフレームに複数のパネルを固定してケーシングを構成していた。
また、例えば特許文献１に開示する空気調和機では、ケーシングを構成する複数のパネのそれそれが鋼板からなる外壁板と内壁板の間に発泡断熱材を注入してなり、外壁板および内壁板の各々の外端縁に折曲部を形成し、外壁板の折曲部と内壁板の折曲部との間に軟質発泡ウレタンシートからなる熱的絶縁材を介装している。 Conventionally, in this type of air conditioner, a casing is configured by fixing a plurality of panels to a frame constituting a structural material as a general structure.
Further, for example, in the air conditioner disclosed in Patent Literature 1, each of the plurality of panels constituting the casing is formed by injecting a foam heat insulating material between an outer wall plate made of a steel plate and an inner wall plate, and each of the outer wall plate and the inner wall plate. A bent portion is formed at the outer edge of the outer wall plate, and a thermal insulating material made of a soft foamed urethane sheet is interposed between the bent portion of the outer wall plate and the bent portion of the inner wall plate.

ケーシングは２つのパネルをＬ字状もしくはＴ字状に配置し、一方のパネルの端面をなす外壁板の折曲部がガスケットを介して他方のパネルの内壁板に当接し、他方のパネルの外壁板側から発泡断熱材および内壁板を貫いてボルトを挿通し、このボルトがガスケットと一方のパネルにおける外壁板の折曲部と熱的絶縁材と内壁板の折曲部とを貫通することで、双方のパネルを連にしている。   The casing has two panels arranged in an L shape or T shape, and the bent portion of the outer wall plate forming the end face of one panel abuts against the inner wall plate of the other panel via a gasket, and the outer wall of the other panel By inserting a bolt through the foam insulation and the inner wall plate from the plate side, this bolt penetrates the bent portion of the outer wall plate and the thermal insulation material and the bent portion of the inner wall plate in one panel. Both panels are connected.

また、特許文献２に開示する空気調和機では、図７および図８に示すように、ケーシングを構成する複数の断熱パネル１のそれぞれが外周縁の枠体２に囲まれた内部に断熱材３を充填してなり、断熱材３の表裏を外壁板１ａと内壁板１ｂが覆っており、枠体２が断熱パネル１の相互間を連結接続する連結手段をなす。そして、枠体２に形成した凹部４に嵌合材５を配置し、相互に対向する枠体２を嵌合材５で連結している。   Moreover, in the air conditioner disclosed in Patent Document 2, as shown in FIGS. 7 and 8, each of the plurality of heat insulating panels 1 constituting the casing is surrounded by a frame 2 on the outer periphery, and the heat insulating material 3 is provided inside. The outer wall plate 1 a and the inner wall plate 1 b cover the front and back of the heat insulating material 3, and the frame body 2 serves as a connecting means for connecting and connecting the heat insulating panels 1 to each other. And the fitting material 5 is arrange | positioned in the recessed part 4 formed in the frame 2, and the frame 2 which mutually opposes is connected with the fitting material 5. FIG.

特開平１０−１１０９６４号公報JP-A-10-110964 特開２００７−２７１１４０号公報JP 2007-271140 A

上記した従来の構成では、空気調和機の容量の増加に伴ってケーシングも大型化し、各断熱パネル１の形状も大きくなる。このため、図７および図８に示すように、断熱パネル１の連結力を補強するためにＬ字型の連結補強ブラケット６を接合対象の断熱パネル１の相互間に配置し、ビス７によって連結補強ブラケット６を断熱パネル１の内壁板１ｂに固定している。   In the conventional configuration described above, the casing becomes larger and the shape of each heat insulating panel 1 becomes larger as the capacity of the air conditioner increases. For this reason, as shown in FIGS. 7 and 8, in order to reinforce the connection force of the heat insulation panel 1, L-shaped connection reinforcement brackets 6 are arranged between the heat insulation panels 1 to be joined and connected by screws 7. The reinforcing bracket 6 is fixed to the inner wall plate 1 b of the heat insulating panel 1.

しかしながら、断熱パネル１の形状が大きくなると凹部４および嵌合材５も大きくなり、凹部４に嵌合材５を押し込むために大きな力が必要となり、組立て作業性が悪くなる。連結補強ブラケット６を固定するビス７は断熱パネル１の薄い肉厚の内壁板１ｂに螺合するので、断熱パネル１に内側から外側へ向けて強い力が作用するとビス７が内壁板１ｂから外れる場合がある。また、断熱パネル１は空気調和機を設置する現場でケーシングに組み立てるので、搬送時もしくは組立て作業時の取り扱い方、さらには設置場所の水平度等によっては、組み上げた状態において断熱パネル１に歪みが生じ、断熱パネル１の連結部に隙間が生じて気密性が損なわれる場合がある。   However, when the shape of the heat insulating panel 1 is increased, the concave portion 4 and the fitting material 5 are also large, and a large force is required to push the fitting material 5 into the concave portion 4, so that the assembling workability is deteriorated. Since the screw 7 for fixing the connection reinforcing bracket 6 is screwed into the thin walled inner wall plate 1b of the heat insulating panel 1, the screw 7 is detached from the inner wall plate 1b when a strong force acts on the heat insulating panel 1 from the inside to the outside. There is a case. Moreover, since the heat insulation panel 1 is assembled into a casing at the site where the air conditioner is installed, the heat insulation panel 1 may be distorted in the assembled state depending on how to handle it during transportation or assembly work, and depending on the level of installation place. This may cause a gap in the connecting portion of the heat insulating panel 1 and impair airtightness.

本発明は上記した課題を解決するものであり、パネル同士の連結部における連結強度を高めるとともに、パネル同士を密接に接合することができる空気調和機を提供することを目的とする。   This invention solves an above-described subject, and it aims at providing the air conditioner which can join panels closely while improving the connection strength in the connection part of panels.

Abutting on the side surface, the connecting tool is inserted from the other heat insulation panel to the end surface of one heat insulation panel, and at least one heat insulation panel has an outer wall plate disposed on the outer surface and an inner wall plate disposed on the inner surface. The outer wall plate and the inner wall plate are bent at the end face side to form a folded portion, and a connecting member for receiving the tightening force of the connector is disposed between the outer wall plate and the inner wall plate. The connecting member has a pressing portion that receives the tightening force of the connecting tool and presses the folded portion toward the inner wall plate of the other heat insulating panel, and the pressing portion extends along the one side of the one heat insulating panel. Existing And features.

また、前記一方の断熱パネルは、連結用部材の押圧部が一方の断熱パネルの前記一辺に沿った平坦部を有し、この平坦部で折込部を押圧することを特徴とする。
また、前記一方の断熱パネルは、外周端面を形成する枠体が外側壁板および内側壁板の折込部を挿入する保持部を有し、保持部が連結用部材の押圧部を受け止め、枠体に囲まれた外側壁板と内側壁板の間に断熱材を充填してなることを特徴とする。 Further, the one heat insulating panel is characterized in that the pressing portion of the connecting member has a flat portion along the one side of the one heat insulating panel, and the folding portion is pressed by the flat portion.
Further, the one insulation panel, has a holding portion frame member forming an outer peripheral end face for inserting the folded portion of the outer wall plate and an inner wall plate, holding portion receiving a pressing portion of the connecting member, the frame member A heat insulating material is filled between the outer wall plate and the inner wall plate surrounded by the inner wall plate .

また、前記枠体は、連結用部材を挿入する位置決め部を有し、位置決め部は、連結用部材の押圧方向と交差する方向において連結具もしくは連結用部材に作用する力を受け止めることを特徴とする。
また、前記連結用部材は、外側壁板または内側壁板に沿った両片部を備え、両片部は、連結用部材の押圧方向と交差する方向において連結具もしくは連結用部材に作用する力を受け止めることを特徴とする。
また、前記一方の断熱パネルは、枠体と連結用部材の少なくとも一方が双方の対向面間に断熱用空間を形成する凹部を有することを特徴とする。 Further, the frame body has a positioning portion for inserting the connecting member, and the positioning portion receives a force acting on the connecting tool or the connecting member in a direction intersecting the pressing direction of the connecting member.

以上のように本発明によれば、一方の断熱パネルの連結用部材がその押圧部で外側壁板と内側壁板の折込部を他方の断熱パネルの内側面に押圧することで、連結具の締付け力を受ける連結用部材の抜け出しを外側壁板と内側壁板の折込部で防止して連結部における連結強度を高めることができ、連結用部材の押圧部が断熱パネルの一辺に沿って延在することで、断熱パネル同士を密接に接合することができる。さらに、連結用部材の押圧部が一方の断熱パネルの一辺に沿った平坦部で折込部を押圧することにより、連結部において断熱パネルに歪みが生じることを防止し、断熱パネルの相互間に隙間が生じて気密性が損なわれることを防止する。   As described above, according to the present invention, the connecting member of one heat insulating panel presses the folded portion of the outer wall plate and the inner wall plate against the inner side surface of the other heat insulating panel at the pressing portion, thereby The connecting member that receives the tightening force can be prevented from being pulled out by the folded portion of the outer wall plate and the inner wall plate, so that the connecting strength at the connecting portion can be increased, and the pressing portion of the connecting member extends along one side of the heat insulating panel. By being present, the heat insulating panels can be closely joined. Furthermore, when the pressing part of the connecting member presses the folding part with a flat part along one side of one of the heat insulating panels, the heat insulating panel is prevented from being distorted in the connecting part, and a gap is formed between the heat insulating panels.

以下、本発明の実施の形態を図面に基づいて説明する。
（全体構造）
図６に示すように、空気調和機のケーシング５１は、側壁をなす複数の壁板パネル５２を立設し、壁板パネル５２の上端に天井部をなす複数の天板パネル５３を配置し、ケーシング５１の内部に隔壁をなす中仕切パネル５４を立設し、各パネルを相互に接合して組み立てた構造をなし、開口部に扉パネル５５を配置しており、別途に骨組の構造材を必要としないフレームレス構造である。なお、図６においては後述する連結用部材１０９を便宜的に可視的に表示しているが、連結用部材１０９はパネル内部に配置するものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Overall structure)
As shown in FIG. 6, the casing 51 of the air conditioner is provided with a plurality of wall plate panels 52 that form side walls, and a plurality of top plate panels 53 that form a ceiling at the upper end of the wall plate panel 52. A partition panel 54 that forms a partition wall is erected inside the casing 51, and each panel is joined to each other for assembly. A door panel 55 is arranged in the opening, and a separate structural material is used. It is a frameless structure that is not required. In FIG. 6, a connecting member 109 to be described later is visibly displayed for convenience, but the connecting member 109 is disposed inside the panel.

壁板パネル５２、天板パネル５３、中仕切パネル５４、扉パネル５５は基本的に同じ断熱パネルの構造を有しており、図１に示すように、壁板パネル５２、天板パネル５３、中仕切パネル５４の断熱パネルは、外側面に配置する外側壁板１０１および内側面に配置する内側壁板１０２を有するとともに、金属薄板からなる外側壁板１０１および内側壁板１０２の周縁部を折り曲げて折込部１０３、１０４を形成している。   The wall panel 52, the top panel 53, the partition panel 54, and the door panel 55 basically have the same heat insulating panel structure. As shown in FIG. 1, the wall panel 52, the top panel 53, The heat insulating panel of the partition panel 54 includes an outer wall plate 101 disposed on the outer surface and an inner wall plate 102 disposed on the inner surface, and bends the peripheral portions of the outer wall plate 101 and the inner wall plate 102 made of a thin metal plate. The folding parts 103 and 104 are formed.

図５に示すように、断熱パネルは、パネル外周端面を形成する樹脂製の枠体１０５が保持部１０６を有し、保持部１０６に形成した溝１０７に外側壁板１０１および内側壁板１０２の折込部１０３、１０４を挿入しており、枠体１０５に囲まれた外側壁板１０１と内側壁板１０２の間に断熱材１０８をなすウレタンを充填している。   As shown in FIG. 5, in the heat insulating panel, a resin frame 105 that forms the outer peripheral end surface of the panel has a holding portion 106, and a groove 107 formed in the holding portion 106 has an outer wall plate 101 and an inner wall plate 102. The folding portions 103 and 104 are inserted, and urethane forming the heat insulating material 108 is filled between the outer wall plate 101 and the inner wall plate 102 surrounded by the frame body 105.

断熱パネル同士の連結部は、壁板パネル５２同士の連結部であっても、壁板パネル５２と中仕切パネル５４との連結部であっても、壁板パネル５２と天板パネル５３との連結部であっても、中仕切パネル５４と天板パネル５３との連結部であっても基本的に同様であり、ここでは、図１に示す壁板パネル５２同士の連結部を例に説明する。   Even if the connection part of heat insulation panels is a connection part of the wall board panels 52, even if it is a connection part of the wall board panel 52 and the partition panel 54, it is between the wall board panel 52 and the top panel 53. Even if it is a connection part, even if it is a connection part of the partition panel 54 and the top panel 53, it is the same fundamentally, and demonstrates here the connection part of the wall board panels 52 shown in FIG. 1 as an example. To do.

断熱パネル同士の連結部では、一方の壁板パネル５２の一辺の端面が他方の壁板パネル５２の内側面にガスケット５６を介して当接している。一方の壁板パネル５２の辺縁部には外側壁板１０１と内側壁板１０２の間に型鋼材等からなる断面コ字状の連結用部材１０９を配置してある。連結用部材１０９は、折込部１０３、１０４の先端間の間隔より幅が広く、かつ連結用部材１０９の両辺部１０９ａと外側壁板１０１の間および内側壁板１０２の間に所定の隙間１１０を有し、この間隙１１０に断熱材１０８を介装している。   In the connecting portion between the heat insulating panels, one end surface of one wall plate panel 52 is in contact with the inner surface of the other wall plate panel 52 via a gasket 56. A connecting member 109 having a U-shaped cross section made of a steel mold or the like is disposed between the outer wall plate 101 and the inner wall plate 102 at the edge of one wall plate panel 52. The connecting member 109 is wider than the interval between the tips of the folding portions 103 and 104, and a predetermined gap 110 is provided between both side portions 109a of the connecting member 109 and the outer wall plate 101 and between the inner wall plates 102. And a heat insulating material 108 is interposed in the gap 110.

連結用部材１０９は少なくとも両肩部が枠体１０５の保持部１０６に当接する押圧部１１１をなす。押圧部１１１は一方の壁板パネル５２の一辺に沿って延在する平坦部１１２を形成しており、枠体１０５の保持部１０６を介して平坦部１１２で折込部１０３、１０４を押圧する。   The connecting member 109 forms a pressing portion 111 with at least both shoulder portions coming into contact with the holding portion 106 of the frame body 105. The pressing portion 111 forms a flat portion 112 extending along one side of one wall plate panel 52, and the folding portions 103 and 104 are pressed by the flat portion 112 via the holding portion 106 of the frame body 105.

連結用部材１０９に対向する枠体１０５の対向面には断熱用空間を形成する凹部１１３を形成している。しかしながら、連結用部材１０９と枠体１０５の対向面間に断熱用空間を形成する凹部は枠体１０５と連結用部材１０９の少なくとも一方に形成すればよい。   A concavity 113 that forms a heat insulating space is formed on the facing surface of the frame 105 facing the connecting member 109. However, a recess that forms a heat insulating space between the facing surfaces of the connecting member 109 and the frame 105 may be formed in at least one of the frame 105 and the connecting member 109.

他方の壁板パネル５２から一方の壁板パネル５２の端面にボルトからなる連結具１１４を挿入し、連結用部材１０９の螺子孔１１５に連結具１１４を螺合させている。この連結具１１４の締付け力を受ける連結用部材１０９の押圧部１１１を枠体１０５の保持部１０６が受け止め、押圧部１１１は平坦部１１２で枠体１０５の保持部１０６を介して折込部１０３、１０４を他方の壁板パネル５２の内側壁板１０２に向けて押圧する。   A connector 114 made of a bolt is inserted into the end surface of the one wall plate panel 52 from the other wall plate panel 52, and the connector 114 is screwed into the screw hole 115 of the connection member 109. The holding portion 106 of the frame body 105 receives the pressing portion 111 of the connecting member 109 that receives the tightening force of the connecting tool 114, and the pressing portion 111 is a flat portion 112 through the holding portion 106 of the frame body 105. 104 is pressed toward the inner wall plate 102 of the other wall plate panel 52.

上記した構成により、従来のような連結補強ブラケットを必要とせずに、断熱パネル同士が直接的に密着することで、断熱パネル同士を９０度の角度を保って連結する保持力が高まり、ケーシング５１の剛性が向上する。   With the above-described configuration, the heat-insulating panels are directly brought into close contact with each other without the need for a connection reinforcing bracket as in the prior art, so that the holding power for connecting the heat-insulating panels with an angle of 90 degrees is increased, and the casing 51 The rigidity is improved.

すなわち、一方の断熱パネル、ここでは壁板パネル５２の連結用部材１０９がその押圧部１１１で外側壁板１０１と内側壁板１０２の折込部１０３、１０４を他方の断熱パネル、ここでは壁板パネル５２の内側面に押圧することで、連結具１１４の締付け力を受ける連結用部材１０９の抜け出しを外側壁板１０１と内側壁板１０２の折込部１０３、１０４で防止して連結部１１４における連結強度を高めることができるとともに、連結用部材１０９の押圧部１１１が断熱パネルの一辺に沿って延在することで、断熱パネル同士を密接に接合することができる。このため、従来の構成と同強度を確保するための連結具１１４の本数が半減し、従来において必要であった断熱パネル間の嵌合材が不要となり、組立ての作業性が向上する。また、断熱パネルの辺縁部に連結用部材１０９の型鋼材を配置することで、断熱パネルの単体としての曲げ剛性が向上し、ケーシング５１の内圧を受けて外側へ撓むことを防止する。   That is, one of the heat insulating panels, here, the connecting member 109 of the wall plate panel 52 is the pressing portion 111, and the folded portions 103, 104 of the outer wall plate 101 and the inner wall plate 102 are connected to the other heat insulating panel, here the wall plate panel. 52, the connecting member 109 that receives the tightening force of the connector 114 is prevented from being pulled out by the folding portions 103 and 104 of the outer wall plate 101 and the inner wall plate 102, and the connection strength at the connection portion 114 is prevented. In addition, the pressing portion 111 of the connecting member 109 extends along one side of the heat insulating panel, so that the heat insulating panels can be joined closely. For this reason, the number of connecting members 114 for securing the same strength as that of the conventional configuration is reduced by half, and the fitting material between the heat insulating panels, which has been necessary in the prior art, becomes unnecessary, and the assembling workability is improved. In addition, by arranging the shape steel material of the connecting member 109 at the edge of the heat insulating panel, the bending rigidity of the heat insulating panel as a single unit is improved, and the inner pressure of the casing 51 is prevented from being bent outward.

さらに、連結用部材１０９の押圧部１１１が一方の壁板パネル５２の一辺に沿った平坦部１１２で折込部１０３、１０４を押圧することにより、連結部において壁板パネル５２に歪みが生じることを防止し、壁板パネル５２の相互間に隙間が生じて気密性が損なわれることを防止する。   Furthermore, when the pressing portion 111 of the connecting member 109 presses the folding portions 103 and 104 with the flat portion 112 along one side of the one wall plate panel 52, the wall plate panel 52 is distorted at the connecting portion. This prevents a gap from being generated between the wall panel 52 and impairing the airtightness.

また、保持部１０６が連結用部材１０９の押圧部１１１を受け止めることにより、押圧部１１１は断熱材１０８を介することなく保持部１０６、折込部１０３、１０４を押圧して挟持固定するので、連結強度をより高めることができる。   Further, since the holding portion 106 receives the pressing portion 111 of the connecting member 109, the pressing portion 111 presses and holds the holding portion 106 and the folding portions 103 and 104 without using the heat insulating material 108. Can be further enhanced.

枠体１０５と連結用部材１０９の少なくとも一方が双方の対向面間に断熱用空間を形成する凹部１１３を有することで、あるいは外側壁板１０１と連結用部材１０９の間および内側壁板１０２と連結用部材１０９の間に所定の隙間１１０を有し、さらには隙間１１０に断熱材１０８を介装することで、連結部の断熱性が向上し、結露防止および熱損失の低減を実現できる。   At least one of the frame body 105 and the connecting member 109 has a recess 113 that forms a heat insulating space between the opposing surfaces, or is connected between the outer wall plate 101 and the connecting member 109 and with the inner wall plate 102. By providing a predetermined gap 110 between the members 109 and further interposing the heat insulating material 108 in the gap 110, the heat insulating property of the connecting portion is improved, and it is possible to prevent condensation and reduce heat loss.

また、枠体１０５が連結用部材１０９に対する位置決め部１２１を有することで、パネル成型時に連結用部材１０９の位置決めが容易になる。また、連結部の捩れにより連結具１１４や連結用部材１０９に押圧方向と交差する方向に力が掛かってもその力を位置決め部１２１で受け止めるので、連結を保持する力が高まるとともに、連結用部材１０９が外側壁板１０１または内側壁板１０２に接触することを防いで断熱性が損なわれることを防止する。   Further, since the frame body 105 has the positioning portion 121 with respect to the connecting member 109, the positioning of the connecting member 109 becomes easy during panel molding. Further, even if a force is applied to the connector 114 or the connecting member 109 in the direction intersecting the pressing direction due to the twist of the connecting portion, the force is received by the positioning portion 121, so that the force for holding the connection is increased and the connecting member is increased. 109 is prevented from contacting the outer wall plate 101 or the inner wall plate 102 to prevent the heat insulation from being impaired.

また、連結用部材１０９は外側壁板１０１または内側壁板１０２に沿うように両片部１０９ａを設けているので、連結具１１４や連結用部材１０９に押圧方向と交差する方向に力が掛かっても、その力を両片部１０９ａで受け止めるので連結を保持する力を高めることができる。   In addition, since the connecting member 109 is provided with both pieces 109a along the outer wall plate 101 or the inner wall plate 102, a force is applied to the connecting tool 114 and the connecting member 109 in a direction crossing the pressing direction. However, since the force is received by both pieces 109a, the force for maintaining the connection can be increased.

連結用部材１０９は、図６に示すように、壁板パネル５２、天板パネル５３、中仕切パネル５４の何れにも任意の要所に設けることが可能であり、ケーシング５１の要所に連結用部材１０９を配置することで、フレームレスであるにも拘わらず、フレーム構造に匹敵する筐体強度を実現できる。   As shown in FIG. 6, the connecting member 109 can be provided at any important point on the wall panel 52, the top panel 53, or the partition panel 54, and is connected to the important part of the casing 51. By disposing the member 109, the housing strength comparable to the frame structure can be realized in spite of being frameless.

図２に示すように、枠体１０５には断熱空間を形成する凹部１１３を閉空間部１１６として形成することも可能であり、連結具１１４に螺合する連結用部材１０９と外側壁板１０１の間および連結用部材１０９と内側壁板１０２の間を大きく隔てることにより、連結部の断熱性を高めることができ、結露防止および熱損失の低減を促進することができる。この場合に、連結用部材１０９は枠体１０５との間の断熱材１０８を介して折込部１０３、１０４を押圧する。   As shown in FIG. 2, a recess 113 that forms a heat insulating space can be formed as a closed space 116 in the frame 105, and the connection member 109 and the outer wall plate 101 that are screwed into the connection tool 114 are formed. By separating the space between the connecting member 109 and the inner wall plate 102, the heat insulating property of the connecting portion can be enhanced, and condensation prevention and reduction of heat loss can be promoted. In this case, the connecting member 109 presses the folding portions 103 and 104 via the heat insulating material 108 between the connecting member 109 and the frame body 105.

連結用部材１０９は断面コ字状の型鋼材に限るものではなく、種々の形状のものを採用できる。図３に示すように、板材の中央部に浅溝１１７を設けた連結用部材１１８でもよく、あるいは図４に示すように、板材の中央部にＶ字状溝１１９を設けた連結用部材１２０でもよい。   The connecting member 109 is not limited to a steel shape having a U-shaped cross section, and various shapes can be employed. As shown in FIG. 3, it may be a connecting member 118 provided with a shallow groove 117 in the center portion of the plate material, or as shown in FIG. 4, a connecting member 120 provided with a V-shaped groove 119 in the center portion of the plate material. But you can.
