Description

本発明は、分離型空気調和機の室内機であって、特に直方体形状の室内機の長手方向中央部に配置して室内機の前面を保護する緩衝材に関する。 The present invention relates to a cushioning material for a split-type air conditioner indoor unit, particularly a cushioning material that is placed in the longitudinal center of a rectangular parallelepiped indoor unit to protect the front of the indoor unit.

直方体形状の室内機は、通常、室内機の長手方向の両端部に端部緩衝材（例えば特許文献１の緩衝材）を装着し、室内機の長手方向の一端から筒状の梱包材で包み込むことで梱包される。
ここで、室内機の前面には、風向板が配置されている。風向板は回動することが可能なように吹き出し口に軸支されており、軸同士の間は固定されていないため機械的強度が低い。室内機の輸送中にコンテナ内が高温になった場合、室内機の前面と梱包材との間に空間があると、風向板がたわむおそれがある。そこで、室内機の前面と梱包材との間の空間を埋めるように、室内機の前面に中央緩衝材を配置し、風向板を保護するようにしている。 Rectangular indoor units are typically packaged by attaching end cushioning material (such as the cushioning material described in Patent Document 1) to both longitudinal ends of the indoor unit and wrapping one longitudinal end of the indoor unit in tubular packaging material.
Here, an air deflector is placed on the front of the indoor unit. The air deflector is supported on the outlet so that it can rotate, and the shafts are not fixed to each other, so the mechanical strength is low. If the temperature inside the container becomes high during transportation of the indoor unit, there is a risk that the air deflector will bend if there is a space between the front of the indoor unit and the packaging material. Therefore, a central cushioning material is placed on the front of the indoor unit to fill the space between the front of the indoor unit and the packaging material, and to protect the air deflector.

特開２００９－９０９９４号公報JP 2009-90994 A

ところで、一般に、室内機の中央緩衝材として使用される部材は直方体形状のものであり、風向板の中央部のみを支えるように設けられていた。この直方体形状の中央緩衝材と室内機の接触面積が小さいため、梱包の際に筒状の梱包材との摩擦により外れてしまい、梱包作業を容易に行うことができない。
そこで、本発明は、このような課題を解決するためになされたものであり、室内機の前面への固定作業を簡素化して梱包作業を容易に行うことができるとともに、室内機の前面の保護を行うことができる緩衝材を提供することを目的としている。 Generally, the member used as the central cushioning material for the indoor unit is rectangular and is provided to support only the center of the airflow direction plate. Because the contact area between the rectangular central cushioning material and the indoor unit is small, friction between the central cushioning material and the cylindrical packaging material during packaging causes it to come off, making packaging difficult.
Therefore, the present invention has been made to solve such problems, and aims to provide a cushioning material that can simplify the fixing work to the front of the indoor unit, making packaging work easier, and also protect the front of the indoor unit.

上記目的を達成するために、本発明の一態様に係る緩衝材は、直方体形状の室内機の前面に着脱自在に固定され、筒状の梱包材の内部に配置される緩衝材であって、梱包材の梱包材内壁に面接触する梱包材接触面と、室内機の前面の一部に面接触する室内機接触面と、を備えている。 To achieve the above object, the cushioning material according to one aspect of the present invention is a cushioning material that is removably fixed to the front surface of a rectangular parallelepiped indoor unit and placed inside a cylindrical packaging material, and has a packaging material contact surface that is in surface contact with the inner wall of the packaging material, and an indoor unit contact surface that is in surface contact with a portion of the front surface of the indoor unit.

本発明に係る緩衝材によれば、室内機および梱包材のそれぞれと緩衝材との接触面積を大きくすることにより室内機の前面への固定作業を簡素化して梱包作業を容易に行うことができるとともに、室内機の前面の保護機能を向上させることができる。 The cushioning material of the present invention increases the contact area between the cushioning material and both the indoor unit and the packaging material, simplifying the work of fixing the indoor unit to the front surface, making packaging easier, and improving the protection function of the front surface of the indoor unit.

In addition, the terms indicating directions such as "up,""down,""front,""back,""left," and "right" used in the following explanation are based on the state in which the air conditioner's indoor unit is attached to a wall inside a room.

図１は、壁掛け型の室内機１が梱包されている状態を示しており、図２は、図１のII-II線矢視図である。
室内機１は壁掛け型の室内機であって、筐体内部に、図示しない送風ファン、熱交換機、電気部品等を取り付けたドレンパン組立体などが収納されている。筐体は、図２に示すように、室内機１の上面を構成する上面パネル２と、室内機１の前面に配置され、前面平面部３ａ及び曲率を有する前面曲面部３ｂを有している前面パネル３と、前面パネル３の前面曲面部３ｂとの間に矩形状の空間を設けて配置されている底面パネル４と、前面パネル３の前面平面部３ａに対して平行に対向して裏側に配置され、室内の壁に固定可能な金属板からなる図示しない据付板が取り付けられる背面板５と、上面パネル２、前面パネル３、底面パネル４及び背面板５の長手方向両端に直交して配置された１対の側面パネル６，６（図１参照）とを備えている。前面平面部３ａは上面パネル２の前面、前面曲面部３ｂは上面パネル２の前面から底面に向けて傾斜している。なお、上面パネル２には吸い込み口（不図示）が設けられており、前面パネル３の前面曲面部３ｂ及び底面パネル４の間の矩形状の空間は吹き出し口とされ、この吹き出し口に風向板７が回動自在に配置されている。 FIG. 1 shows a wall-mounted indoor unit 1 in a packaged state, and FIG. 2 is a cross-sectional view taken along line II-II in FIG.
The indoor unit 1 is a wall-mounted indoor unit, and a drain pan assembly to which a blower fan, a heat exchanger, electric parts, etc. (not shown) are attached is housed inside the housing. As shown in Fig. 2, the housing includes an upper panel 2 constituting the upper surface of the indoor unit 1, a front panel 3 arranged on the front side of the indoor unit 1 and having a front flat portion 3a and a front curved portion 3b having a curvature, a bottom panel 4 arranged with a rectangular space between the front curved portion 3b of the front panel 3, a back panel 5 arranged on the back side parallel to and facing the front flat portion 3a of the front panel 3, and to which an installation plate (not shown) made of a metal plate that can be fixed to a wall inside the room is attached, and a pair of side panels 6, 6 (see Fig. 1) arranged perpendicularly to both ends of the longitudinal direction of the upper panel 2, the front panel 3, the bottom panel 4, and the back panel 5. The front flat portion 3a is inclined toward the front surface of the upper panel 2, and the front curved portion 3b is inclined from the front surface of the upper panel 2 toward the bottom surface. In addition, an intake port (not shown) is provided in the top panel 2, and the rectangular space between the front curved portion 3b of the front panel 3 and the bottom panel 4 is an outlet port, and a wind deflector 7 is arranged at this outlet port so that it can be freely rotated.

そして、室内機１の梱包姿勢は、剛性の高い背面板５が下側とされており、室内機１の長手方向両端部に一対の端部緩衝材８，８が装着され、室内機１の長手方向中央部に風向板７の外周を横切るように中央緩衝材９が配置されているとともに、室内機１、端部緩衝材８，８及び中央緩衝材９を覆うように、四角筒状の段ボールからなる梱包材１０で梱包されている。
一対の端部緩衝材８，８は、発泡ポリスチレンなどの発泡材で形成された部材であり、室内機１の側面パネル６の外面全体を覆いながら上面パネル２、前面パネル３、底面パネル４及び背面板５の一部を覆って装着されている。 The indoor unit 1 is packed in such a manner that the highly rigid back panel 5 is at the bottom, a pair of end cushioning materials 8, 8 are attached to both longitudinal ends of the indoor unit 1, a central cushioning material 9 is arranged in the longitudinal centre of the indoor unit 1 across the outer periphery of the air direction plate 7, and the indoor unit 1 is packed in packaging material 10 made of square cylindrical cardboard so as to cover the indoor unit 1, the end cushioning materials 8, 8 and the central cushioning material 9.
The pair of end cushioning materials 8, 8 are members formed from a foam material such as expanded polystyrene, and are attached so as to cover the entire outer surface of the side panel 6 of the indoor unit 1 while also covering parts of the top panel 2, front panel 3, bottom panel 4 and back panel 5.

梱包材１０は、図１、図２に示すように、段ボールを材料として長方形の開口を有する筒状部材である。
一方、本願における緩衝材としての中央緩衝材９は、発泡ポリスチレンなどの発泡材で形成した長尺の部材であり、図３（ａ）、（ｂ）に示すように、矩形平面状の第１梱包材接触面１１及び第２梱包材接触面１２が互いに直交して形成されている。また、これら第１及び第２梱包材接触面１１，１２に対向する側に、前面曲面部３ｂおよび底面パネル４の形状に合わせて湾曲した曲面形状の室内機接触面１３が形成されている。これにより、中央緩衝材９は、第１梱包材接触面１１を形成した部位９ａの奥行き寸法Ｌ１が大きく（以下、大形緩衝部９ａと称する）、第２梱包材接触面１２の先端側の部位９ｂの奥行き寸法Ｌ２が小さい（以下、小形緩衝部９ｂと称する）、略楔形状に形成された部材である。そして、図３（ａ）、（ｂ）に示すように、第１梱包材接触面１１及び第２梱包材接触面１２の四角には、Ｃ面形状の面取り１４が形成されている。なお、面取り１４の形状は、Ｃ面形状に限らず、Ｒ面形状であってもよい。 As shown in Figs. 1 and 2, the packaging material 10 is a tubular member made of corrugated cardboard and having a rectangular opening.
On the other hand, the central cushioning material 9 as the cushioning material in the present application is a long member formed of a foam material such as expanded polystyrene, and as shown in Figures 3(a) and (b), the first packaging material contact surface 11 and the second packaging material contact surface 12, which are rectangular flat surfaces, are formed perpendicular to each other. In addition, on the side facing these first and second packaging material contact surfaces 11 and 12, a curved indoor unit contact surface 13 is formed that is curved to match the shape of the front curved surface portion 3b and the bottom panel 4. As a result, the central cushioning material 9 is a member formed in a substantially wedge shape, with the depth dimension L1 of the portion 9a forming the first packaging material contact surface 11 being large (hereinafter referred to as the large cushioning portion 9a) and the depth dimension L2 of the portion 9b on the tip side of the second packaging material contact surface 12 being small (hereinafter referred to as the small cushioning portion 9b). And, as shown in Figures 3(a) and (b), C-shaped chamfers 14 are formed at the four corners of the first packaging material contact surface 11 and the second packaging material contact surface 12. The shape of the chamfer 14 is not limited to a C-surface shape, but may be an R-surface shape.

そして、この中央緩衝材９は、室内機１の長手方向の中央部に風向板７を横切るように配置される。そして、中央緩衝材９の一部と前面パネル３及び底面パネル４は、粘着テープ（不図示）が貼り付けられ、中央緩衝材９は前面パネル３及び底面パネル４に着脱自在に固定される。
上記構成の中央緩衝材９は、図２に示すように、四角筒形状の梱包材１０の互いに直交する梱包材内壁１０ａ，１０ｂの一方の梱包材内壁１０ａに第１梱包材接触面１１が面接触し、他方の梱包材内壁１０ｂに第２梱包材接触面１２が面接触し、室内機接触面１３が、室内機１の前面パネル３の前面曲面部３ｂ及び底面パネル４に面接触した状態で配置される。なお、本発明に記載されている梱包材接触面が、第１梱包材接触面１１及び第２梱包材接触面１２に対応している。 This central cushioning material 9 is disposed in the center of the longitudinal direction of the indoor unit 1 so as to cross the airflow direction plate 7. A part of the central cushioning material 9 and the front panel 3 and bottom panel 4 are attached with adhesive tape (not shown), and the central cushioning material 9 is removably fixed to the front panel 3 and bottom panel 4.
2, the central cushioning material 9 having the above-mentioned configuration is arranged in such a manner that the first packaging material contact surface 11 is in surface contact with one of the mutually orthogonal packaging material inner walls 10a, 10b of the rectangular cylindrical packaging material 10, the second packaging material contact surface 12 is in surface contact with the other packaging material inner wall 10b, and the indoor unit contact surface 13 is in surface contact with the front curved surface portion 3b and the bottom panel 4 of the front panel 3 of the indoor unit 1. Note that the packaging material contact surfaces described in the present invention correspond to the first packaging material contact surface 11 and the second packaging material contact surface 12.

ここで、図４は、室内機１に固定されている中央緩衝材９の他の実施形態を示したものである。
室内機１を壁面へ設置する作業を行うにあたって、まず室内機１から梱包材１０及び端部緩衝材８を取り除いた後、室内機１の面積の小さい部分を下、面積の大きい部分を上として配置する。すなわち、背面板５を上側に位置し、前面パネル３の前面平面部３ａを下側として床面または作業台に設置する。このとき、前面パネル３の前面平面部３ａは背面板５と比較して面積が小さい形状なので、室内機１のバランスがとりにくく自立が難しい。しかし、中央緩衝材９の大形緩衝部９ａが作業台に当接して中央緩衝材が自立補助具として機能することで、室内機１の自立が可能となる。このように、面積の小さい部分を下にした室内機１の自立を補助する自立補助具として央緩衝材９を使用することで、図４に示すように、背面板５を外した状態で室内機１内部の配管作業を容易に行うことが可能となる。 Here, FIG. 4 shows another embodiment of the central cushioning material 9 fixed to the indoor unit 1. In FIG.
When installing the indoor unit 1 on a wall, first remove the packaging material 10 and the end cushioning material 8 from the indoor unit 1, and then place the indoor unit 1 with the smaller area on the bottom and the larger area on the top. That is, place the rear panel 5 on the top and the front flat surface 3a of the front panel 3 on the bottom, and install it on the floor or workbench. At this time, since the front flat surface 3a of the front panel 3 has a smaller area than the rear panel 5, it is difficult to balance the indoor unit 1 and make it self-supporting. However, the large cushioning portion 9a of the central cushioning material 9 abuts against the workbench and functions as a self-supporting aid, making it possible for the indoor unit 1 to stand on its own. In this way, by using the central cushioning material 9 as a self-supporting aid that helps the indoor unit 1 stand on its own with the smaller area on the bottom, it becomes possible to easily perform piping work inside the indoor unit 1 with the rear panel 5 removed, as shown in FIG. 4.

上述したように、本実施形態の中央緩衝材９は、室内機１の長手方向の中央部に風向板７を横切るように配置されるため、第１梱包材接触面１１が梱包材内壁１０ａに面接触し、第１梱包材接触面１１に直交する第２梱包材接触面１２が梱包材内壁１０ａに直交する梱包材内壁１０ｂに面接触し、室内機接触面１３が前面パネル３の前面曲面部３ｂ及び底面パネル４の間を覆うことで、室内機１の機械的強度が低い風向板７を確実に保護することができる。 As described above, in this embodiment, the central cushioning material 9 is positioned across the wind deflector 7 in the longitudinal center of the indoor unit 1, so that the first packaging contact surface 11 is in surface contact with the packaging inner wall 10a, the second packaging contact surface 12 perpendicular to the first packaging contact surface 11 is in surface contact with the packaging inner wall 10b perpendicular to the packaging inner wall 10a, and the indoor unit contact surface 13 covers the area between the front curved portion 3b of the front panel 3 and the bottom panel 4, thereby reliably protecting the wind deflector 7 of the indoor unit 1, which has low mechanical strength.

そして、室内機１の長手方向の両端部に端部緩衝材８を装着し、室内機１の長手方向中央部に中央緩衝材９を配置してしているので、室内機１の積み上げ保管時に、梱包材１０の中央部が凹むことを防止することができる。
また、中央緩衝材９の第１梱包材接触面１１及び第２梱包材接触面１２の四角は、Ｃ面形状の面取り１４が形成されているので、梱包材１０の梱包作業を行うときに、梱包材１０の縁部が中央緩衝材９の第１梱包材接触面１１及び第２梱包材接触面１２に引っ掛かりにくくなり、梱包材１０の梱包作業を容易に短時間で行うことができる。
さらに、面積の小さい部分を下にした室内機１の自立補助具として中央緩衝材９を使用すると、背面板５を上に向けた状態で室内機１内部の配管作業を容易に行うことができる。 End cushioning materials 8 are attached to both longitudinal ends of the indoor unit 1, and a central cushioning material 9 is arranged in the longitudinal center of the indoor unit 1, so that the central part of the packaging material 10 can be prevented from being dented when the indoor units 1 are stacked for storage.
In addition, the four corners of the first packaging material contact surface 11 and the second packaging material contact surface 12 of the central cushioning material 9 are formed with C-shaped chamfers 14, so that when the packaging material 10 is being packed, the edges of the packaging material 10 are less likely to get caught on the first packaging material contact surface 11 and the second packaging material contact surface 12 of the central cushioning material 9, making it easy to pack the packaging material 10 in a short amount of time.
Furthermore, by using the central cushioning material 9 as an aid for supporting the indoor unit 1 with the smaller area facing downwards, piping work inside the indoor unit 1 can be easily carried out with the rear panel 5 facing upwards.
