Description

本発明は、冷媒配管接続部が本体から外部へ突出され、本体の冷媒配管接続部が貫通する開口が冷媒配管接続部を除きパネルで覆われてなる空気調和機に関する。   The present invention relates to an air conditioner in which a refrigerant pipe connection portion projects outward from a main body, and an opening through which the refrigerant pipe connection portion of the main body passes is covered with a panel except for the refrigerant pipe connection portion.

従来より、冷媒配管接続部が本体から外部へ突出され、本体の冷媒配管接続部が貫通する開口が冷媒配管接続部を除きパネルで覆われてなる空気調和機において、前記パネルを、前記冷媒配管接続部の配設位置を境にして分割された上下２つのパネルで構成するとともに、冷媒配管の下側に位置するパネルは垂直方向にスライドさせることで着脱可能である構成として、容易に取り付け、取り外しすることができるようにしたものがある（例えば、特許文献１参照）。   Conventionally, in an air conditioner in which a refrigerant pipe connection portion protrudes from the main body and an opening through which the refrigerant pipe connection portion of the main body passes is covered with a panel except for the refrigerant pipe connection portion, the panel is connected to the refrigerant pipe. It is composed of two upper and lower panels divided with the connection position as a boundary, and the panel located on the lower side of the refrigerant pipe can be attached and detached easily by sliding in the vertical direction, There is one that can be removed (for example, see Patent Document 1).

また、空気調和機本体の外殻を構成している板金製の箱型の本体ケースの側面を切り欠いて冷媒配管導出用の切欠部を形成し、この切欠部を覆うように配管押え板を取り付け、配管押え板に冷媒配管を押えるＵ字溝を形成し、このＵ字溝の各々の縁部に、例えばバーリング加工等によって折曲片を形成し、これらの折曲片が前記冷媒配管の外周面と面接触するようにしたものも提案されている（例えば、特許文献２参照）。   In addition, the side of the sheet metal box-shaped main body case that forms the outer shell of the air conditioner body is cut away to form a cutout portion for leading out the refrigerant pipe, and a pipe presser plate is installed to cover this cutout portion. A U-shaped groove for holding the refrigerant pipe is formed on the pipe holding plate, and a bent piece is formed on each edge of the U-shaped groove by, for example, burring, etc., and these bent pieces are formed on the refrigerant pipe. Some have been proposed that are in surface contact with the outer peripheral surface (see, for example, Patent Document 2).

特開平０１−１２３９２６号公報（第１図）Japanese Patent Laid-Open No. 01-123926 (FIG. 1) 特開２００６−０９７９９６号公報（図７〜図９）Japanese Patent Laying-Open No. 2006-097996 (FIGS. 7 to 9)

しかしながら、本体の冷媒配管接続部が貫通する開口を覆うパネルを冷媒配管接続部の配設位置を境にして分割された上下２つのパネルで構成し、単に冷媒配管の下側に位置するパネルを垂直方向にスライドして着脱可能としたものにあっては、本体内部にある熱交換器の洗浄や修理といったサービスの作業性を向上させることを主な目的としているため、空気調和機内部で熱交換されて冷やされた冷気が分割されたパネル間の隙間から洩れるのを防止する対策が十分でなく、冷気洩れによる結露を防止できなかった。   However, the panel that covers the opening through which the refrigerant pipe connection part of the main body passes is composed of two upper and lower panels that are divided with the refrigerant pipe connection part as a boundary, and the panel that is simply located below the refrigerant pipe For those that can be removed by sliding vertically, the main purpose is to improve the workability of services such as cleaning and repairing the heat exchanger inside the main unit. Measures to prevent the exchanged and cooled cold air from leaking through the gaps between the divided panels were not sufficient, and condensation due to cold air leakage could not be prevented.

また、本体ケースの側面に冷媒配管導出用の切欠部を形成し、この切欠部を覆うように配管押え板を取り付け、配管押え板に冷媒配管を押えるＵ字溝を形成し、このＵ字溝の各々の縁部に、バーリング加工等によって折曲片を形成したものにあっては、板金を９０°折り曲げて形成したものであるため、板金加工の際に生ずるバリにより、組立作業やサービス作業の際に作業者が手を切ってしまうなど、作業性、安全性に課題を残していた。   Also, a notch for leading out the refrigerant pipe is formed on the side surface of the main body case, a pipe holding plate is attached so as to cover the notch, and a U-shaped groove for holding the refrigerant pipe is formed on the pipe holding plate. In the case of bent pieces formed by burring or the like at each edge of the sheet metal, since the sheet metal is bent 90 °, assembly work and service work are caused by burrs generated during sheet metal processing. There were still problems in workability and safety.

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、本体の冷媒配管接続部が貫通する開口を覆うパネルを分割構成とする場合において、冷気洩れによる結露を防止でき、かつ組立作業やサービス作業時の作業性、安全性を向上させることができるようにすることを目的としている。   The present invention has been made to solve the above-described problems. In the case where the panel covering the opening through which the refrigerant pipe connection portion of the main body passes is divided, it is possible to prevent condensation due to cold air leakage and to assemble the panel. It is intended to improve workability and safety during work and service work.

本発明に係る空気調和機は、断熱性を有する弾性体で構成されたパイプカバーで覆われた冷媒配管接続部が本体から外部へ突出され、前記本体の前記冷媒配管接続部が貫通する開口が、前記パイプカバーで覆われた前記冷媒配管接続部を除きパネルで覆われてなる空気調和機において、前記パネルが、前記冷媒配管接続部の配設位置を境にして分割された２つのパネルで構成されているとともに、これら２つのパネルには前記パイプカバーで覆われた前記冷媒配管接続部を挟み込むためのＵ字溝がそれぞれ形成されており、かつ一方のパネルは着脱可能に構成され、その前記Ｕ字溝の縁部にはカーリングが形成されているものである。   In the air conditioner according to the present invention, the refrigerant pipe connection portion covered with a pipe cover made of an elastic body having heat insulation properties projects from the main body to the outside, and the opening through which the refrigerant pipe connection portion of the main body passes is provided. In the air conditioner that is covered with a panel except for the refrigerant pipe connection portion covered with the pipe cover, the panel is divided into two panels separated by the arrangement position of the refrigerant pipe connection portion. These two panels are each formed with U-shaped grooves for sandwiching the refrigerant pipe connection portion covered with the pipe cover, and one panel is configured to be removable. Curling is formed at the edge of the U-shaped groove.

本発明に係る空気調和機においては、着脱可能に構成されたパネルのＵ字溝の縁部にカーリングが形成されているので、バリが無く、パネルがパイプカバーの表面を滑り易くなり、パネルがパイプカバーに引っ掛かることが無く、組立作業やサービス作業時の作業性、安全性が向上し、かつ密着性が高くなる。このため、空気調和機内部で熱交換されて冷やされた冷気が、分割されたパネル間の隙間から洩れるのを防止することができ、冷気洩れによる結露を未然に防止することができる。   In the air conditioner according to the present invention, curling is formed at the edge of the U-shaped groove of the detachable panel, so that there is no burr and the panel easily slides on the surface of the pipe cover. It does not get caught in the pipe cover, improving workability and safety during assembly work and service work, and improving adhesion. For this reason, it is possible to prevent cold air that has been cooled by heat exchange inside the air conditioner from leaking through the gaps between the divided panels, and it is possible to prevent condensation due to cold air leakage.

図１は本発明の実施形態に係る空気調和機の化粧パネルを外し下面側を上にした状態を示す斜視図である。本発明の実施形態に係る空気調和機は、天井埋込型の空気調和機である。この空気調和機は、図１及び図２のように本体１の外殻が、基本的に板金で構成されるドラム２と、ドラム２の冷媒配管接続部１０が貫通する開口（図示せず）を覆う板金製のパネル１１とで構成されている。パネル１１は、冷媒配管接続部１０の配設位置を境にして分割された２つのパネルすなわち上パネル３と下パネル４で構成されている。   FIG. 1 is a perspective view showing a state in which the decorative panel of the air conditioner according to the embodiment of the present invention is removed and the lower surface is turned up. An air conditioner according to an embodiment of the present invention is a ceiling-embedded air conditioner. In this air conditioner, as shown in FIGS. 1 and 2, the outer shell of the main body 1 is basically an opening (not shown) through which the drum 2 composed of sheet metal and the refrigerant pipe connecting portion 10 of the drum 2 penetrate. It is comprised with the panel 11 made from a sheet metal which covers. The panel 11 is composed of two panels, that is, an upper panel 3 and a lower panel 4 that are divided at the position where the refrigerant pipe connection portion 10 is disposed.

図２は本発明の実施形態に係る空気調和機の要部である冷媒配管接続部付近を拡大して示す斜視図、図３は本発明の実施形態に係る空気調和機の着脱可能なパネルの拡大斜視図、図４は本発明の実施形態に係る空気調和機の着脱可能なパネルのカーリング部の拡大側面図である。冷媒配管接続部１０は、図２のように液冷媒配管５とガス冷媒配管６とで構成され、これらは本体１の前記開口の開口面の横幅方向に位置がずれ、かつ全体として外側寄りに偏位して配置されていて、配管接続作業時の作業空間を確保できるようになっている。また、液冷媒配管５とガス冷媒配管６には、断熱及び結露対策としてそれぞれの周囲に断熱性を有する弾性体で構成されたパイプカバー７，８が取り付けられている。また、上パネル３と下パネル４には、パイプカバー７，８で覆われた液冷媒配管５とガス冷媒配管６を挟み込むためのＵ字溝１２ａ，１２ｂ（図３に下パネル４側のＵ字溝のみ示す）がそれぞれ形成されている。Ｕ字溝１２ａ，１２ｂの円弧の径は、パイプカバー７，８の径よりも小さく設定されている。また、一方のパネルすなわち下パネル４（図２は倒伏状態の図であるため上側に示されている）は、着脱可能に構成されており、上パネル３（図２は倒伏状態の図であるため下側に示されている）と本体１とにねじにより止着されるようになっている。さらに、下パネル４には、外側寄りに位置するＵ字溝１２ｂの縁部にカーリング９が形成されている。   FIG. 2 is an enlarged perspective view showing the vicinity of a refrigerant pipe connecting portion, which is a main part of the air conditioner according to the embodiment of the present invention, and FIG. 3 is a diagram of a detachable panel of the air conditioner according to the embodiment of the present invention. FIG. 4 is an enlarged perspective view, and FIG. 4 is an enlarged side view of the curling portion of the detachable panel of the air conditioner according to the embodiment of the present invention. As shown in FIG. 2, the refrigerant pipe connection portion 10 is composed of a liquid refrigerant pipe 5 and a gas refrigerant pipe 6, which are displaced in the lateral width direction of the opening surface of the opening of the main body 1 and outward as a whole. It is arranged in a deviated position so that a work space for pipe connection work can be secured. In addition, pipe covers 7 and 8 made of an elastic body having heat insulation are attached to the liquid refrigerant pipe 5 and the gas refrigerant pipe 6 as heat insulation and condensation countermeasures. Further, the upper panel 3 and the lower panel 4 are provided with U-shaped grooves 12a and 12b for sandwiching the liquid refrigerant pipe 5 and the gas refrigerant pipe 6 covered with the pipe covers 7 and 8 (the U-shaped groove on the lower panel 4 side in FIG. 3). (Only the groove is shown) is formed. The diameters of the arcs of the U-shaped grooves 12 a and 12 b are set smaller than the diameters of the pipe covers 7 and 8. Further, one panel, that is, the lower panel 4 (shown on the upper side because FIG. 2 is a lying state) is configured to be detachable, and the upper panel 3 (FIG. 2 is a lying state). Therefore, it is fixed to the main body 1 with a screw. Further, the lower panel 4 is formed with a curling 9 at the edge of the U-shaped groove 12b located on the outer side.

本発明の実施形態に係る空気調和機は、以上のように構成され、液冷媒配管５及びガス冷媒配管６が、現地にて配管を通じて室外機と接続される。着脱可能な下パネル４は、パイプカバー７，８の表面で軸方向にスライドされ、さらにパイプカバー７，８の径方向に圧縮されることで取り付けられる。その際、下パネル４には、外側寄りに位置するＵ字溝１２ｂの縁部にカーリング９が形成されているため、バリが無く、下パネル４をパイプカバー７，８の表面に引っ掛かけること無く、スムーズに移動させることができ、浮き上がりを防止することができる。また、カーリング９部がパイプカバー７，８の外周面と面接触し、密着性が高くなる。このため、上下パネル３，４間、及び上下パネル３，４とパイプカバー７，８との間に隙間が発生せず、空気調和機内部で熱交換されて冷やされた冷気の漏洩が無くなり、冷気洩れによる結露の発生を未然に防止することができるとともに、組立作業やサービス作業の際に作業者が安全に作業でき、作業性、安全性が向上する。   The air conditioner according to the embodiment of the present invention is configured as described above, and the liquid refrigerant pipe 5 and the gas refrigerant pipe 6 are connected to the outdoor unit through the pipe on site. The detachable lower panel 4 is attached by being slid in the axial direction on the surfaces of the pipe covers 7 and 8 and further compressed in the radial direction of the pipe covers 7 and 8. At that time, since the curling 9 is formed at the edge of the U-shaped groove 12b located on the outer side of the lower panel 4, there is no burr and the lower panel 4 is hooked on the surface of the pipe covers 7, 8. Without being lifted, and can be lifted smoothly. Further, the curling 9 portion comes into surface contact with the outer peripheral surfaces of the pipe covers 7 and 8, and the adhesion is enhanced. For this reason, a gap does not occur between the upper and lower panels 3 and 4 and between the upper and lower panels 3 and 4 and the pipe covers 7 and 8, and there is no leakage of cold air that is cooled by heat exchange inside the air conditioner, Condensation due to cold air leakage can be prevented in advance, and workers can work safely during assembly work and service work, improving workability and safety.

また、カーリング９が補強リブとして働くので、剛性が高くなり、下パネル４のＵ字溝１２ｂと外側辺との間の距離（幅）が、内側寄りに位置するＵ字溝１２ａと内側辺との間の距離（幅）に比べて小さくても、Ｕ字溝１２ｂの円弧の外側端部の組付時の浮き上がりを防止することができる。さらに、取り付け時におけるねじ止め等の外力によって下パネル４が撓んで隙間ができてしまうことを防止できる。   In addition, since the curling 9 serves as a reinforcing rib, the rigidity is increased, and the distance (width) between the U-shaped groove 12b of the lower panel 4 and the outer side is such that the U-shaped groove 12a and the inner side located closer to the inner side. Even if it is smaller than the distance (width) between the two, it is possible to prevent lifting when the outer end of the arc of the U-shaped groove 12b is assembled. Further, it is possible to prevent the lower panel 4 from being bent due to an external force such as screwing at the time of attachment, thereby forming a gap.
