Description

本発明は天井埋込形空気調和機に係り、特にルーバ駆動手段への冷気の進入を防止するためにシール構造を改良した天井埋込形空気調和機に関する。   The present invention relates to a ceiling-embedded air conditioner, and more particularly to a ceiling-embedded air conditioner with an improved seal structure to prevent cold air from entering a louver driving means.

一般に天井埋込形空気調和機は、中央部に吸込口が設けられ、この吸込口を囲うように複数の吹出口が設けられている。   Generally, a ceiling-embedded air conditioner is provided with a suction port at the center, and a plurality of air outlets are provided so as to surround the suction port.

この吹出口には風向を室内の上下方向に変更させるルーバがそれぞれ設けられ、このルーバを駆動させるモータの駆動装置が化粧パネルの裏側に配置され、モータがモータケースに収容されている(例えば、特許文献1参照)。   The air outlets are each provided with a louver that changes the air direction in the vertical direction of the room, a motor driving device for driving the louver is disposed on the back side of the decorative panel, and the motor is accommodated in a motor case (for example, Patent Document 1).

通常、冷房運転時、熱交換器で冷却された空気を吹出ロから吹出すが、特許文献1に記載の天井埋込形空気調和機では、ルーバ駆動装置は吹出口の近傍に配置されるため、モータケースに冷風が侵入し、モータに結露するという不具合がある。
特開2002−115897号公報
Normally, during cooling operation, the air cooled by the heat exchanger is blown out from the blowout air. However, in the ceiling-embedded air conditioner described in Patent Document 1, the louver drive device is disposed in the vicinity of the blowout port. There is a problem that cold air enters the motor case and condensation occurs on the motor.
JP 2002-115897 A

本発明は上述した事情を考慮してなされたもので、駆動手段への冷気進入を阻止し、駆動手段への結露を防止できる天井埋込形空気調和機を提供することを目的とする。   The present invention has been made in consideration of the above-described circumstances, and an object thereof is to provide a ceiling-embedded air conditioner that can prevent cold air from entering the drive means and prevent condensation on the drive means.

本発明の一実施形態に係る天井埋込形空気調和機について図面を参照して説明する。   A ceiling-embedded air conditioner according to an embodiment of the present invention will be described with reference to the drawings.

図1は本発明の一実施形態に係る天井埋込形空気調和機の斜視図であり、本天井埋込形空気調和機の化粧パネルを除去して示す空気調和機本体の斜視図であり、図3は本天井埋込形空気調和機に用いる化粧パネルを裏面から見た平面図である。   FIG. 1 is a perspective view of a ceiling-embedded air conditioner according to an embodiment of the present invention, and is a perspective view of an air conditioner body shown by removing a decorative panel of the ceiling-embedded air conditioner. FIG. 3 is a plan view of a decorative panel used in the ceiling-embedded air conditioner as viewed from the back side.

図1ないし図3に示すように、本発明の一実施形態に係る天井埋込形空気調和機1は、天井に埋め込まれる空気調和機本体2と、この空気調和機本体2の下面を覆う化粧パネル3で構成される。   As shown in FIGS. 1 to 3, a ceiling-embedded air conditioner 1 according to an embodiment of the present invention includes an air conditioner body 2 embedded in a ceiling and a makeup covering the lower surface of the air conditioner body 2. Consists of panel 3.

空気調和機本体2は筐体4を備え、この筐体4には室内熱交換器(図示せず)、室内送風機5などを収容する。   The air conditioner body 2 includes a housing 4, and the housing 4 accommodates an indoor heat exchanger (not shown), an indoor blower 5, and the like.

筐体4は同様の4組の吊り下げ手段6によって天井基材(図示せず)に吊り下げて取り付けられる。   The casing 4 is attached to a ceiling base material (not shown) by four similar sets of suspension means 6.

化粧パネル3は、全体が略四角形をなし、その中央に室内空気を吸い込む吸込口3aと、吸込口3aの周囲に形成した4個の被空調空気を吹き出す吹出口3bを備える。   The decorative panel 3 has a substantially rectangular shape as a whole, and includes a suction port 3a that sucks room air in the center thereof, and a blower outlet 3b that blows out four air-conditioned airs formed around the suction port 3a.

吹出口3bは吸込口3aから吸い込まれ熱交換器で熱交換された室内空気を吹出し、その前面には吹出空気の方向を変更する板状のルーバ7が回動可能に設けられる。   The blowout port 3b blows out indoor air sucked from the suction port 3a and heat-exchanged by the heat exchanger, and a plate-like louver 7 that changes the direction of the blown air is rotatably provided on the front surface thereof.

図4及び図5に示すように、ルーバ7には、各ルーバ7を動作させる駆動手段としてのルーバ駆動用モータ8が各々別個に取付固定され、この駆動用モータ8は、化粧パネル3の裏側に設けたモータ収納部9に収納固定される。   As shown in FIGS. 4 and 5, a louver driving motor 8 as a driving means for operating each louver 7 is separately attached and fixed to the louver 7, and this driving motor 8 is connected to the back side of the decorative panel 3. Is stored and fixed in the motor storage portion 9 provided in

さらに、吹出口3bを囲うように断熱部材である発泡部材10が設けられ、図2に示すドレンパン13に設けられた吹出部13bと連通して熱交換器を介した吹出空気の通風経路が形成される。なお、符号11は、化粧パネル3とドレンパン13との間に配置されるシール部材である。   Further, a foam member 10 as a heat insulating member is provided so as to surround the air outlet 3b, and a ventilation path for the air blown through the heat exchanger is formed in communication with the air outlet 13b provided in the drain pan 13 shown in FIG. Is done. Reference numeral 11 denotes a seal member disposed between the decorative panel 3 and the drain pan 13.

モータ収納部9に固定される駆動用モータ8は、保護部材12によって覆われる。   The driving motor 8 fixed to the motor housing 9 is covered with a protective member 12.

モータ収納部9は隣接する2個のルーバ7を各々別個に動作させるための駆動用モータ8を各々収容するために隣接して設けられ、図3に示すように収納固定された2個の駆動用モータ8を一体的に保護部材12で覆う。   The motor storage unit 9 is provided adjacent to each of the drive motors 8 for separately operating the two adjacent louvers 7 and is stored and fixed as shown in FIG. The motor 8 is integrally covered with the protective member 12.

保護部材12を裏面から見た図6に示すように、保護部材12にはその全周に沿って立上12dが設けられ、さらに、90°の角度を有して配され同一形状の2個のモータ収容凸部12aが設けられ、各々のモータ収容凸部12aに連通する軸用凸部12bを挟むようにして両側(両辺)にリブ12cが設けられる。   As shown in FIG. 6 when the protective member 12 is viewed from the back side, the protective member 12 is provided with rising portions 12d along the entire circumference, and further, two pieces having the same shape and arranged at an angle of 90 °. The motor housing projections 12a are provided, and ribs 12c are provided on both sides (both sides) so as to sandwich the shaft projections 12b communicating with each motor housing projection 12a.

このリブ12cを設けることで、保護部材12と発泡部材10の接触面にリブ12cが介在することになり、リブ12cで発泡部材10を押圧することが可能になり、部品特に発泡部材10の寸法バラツキによる空隙がなくなり、冷気のモータ収容凸部12aへの進入が防止され、駆動用モータ8への結露を防止できる。   By providing the rib 12c, the rib 12c is interposed on the contact surface between the protective member 12 and the foam member 10, and the foam member 10 can be pressed by the rib 12c. The gap due to the variation is eliminated, the cold air is prevented from entering the motor housing convex portion 12a, and the dew condensation on the drive motor 8 can be prevented.

また、空気調和機本体2には、図2に示すように、熱交換器で生成されるドレンを受け吹出口部13bを備えるドレンパン13が設けられ、このドレンパン13には保護部材12のモータ収納凸部12aが嵌まる凹部13aが保護部材12の配置に対応して設けられる。これにより、空気調和機本体の高さ方向の寸法を小さくでき、ルーバ駆動用モータ8がドレンパンによっても断熱されるので結露を確実に防ぐことができる。   In addition, as shown in FIG. 2, the air conditioner body 2 is provided with a drain pan 13 having a drain outlet 13 b that receives the drain generated by the heat exchanger, and the drain pan 13 houses the motor of the protection member 12. Concave portions 13a into which the convex portions 12a are fitted are provided corresponding to the arrangement of the protective member 12. Thereby, the dimension of the height direction of an air conditioner main body can be made small, and since the louver drive motor 8 is thermally insulated also by a drain pan, dew condensation can be reliably prevented.

なお、図7に示すように、リブ12Acは複数個設けてもよく、さらに、リブ12Acの高さを変えてもよく、さらに、発泡部材にもリブを形成するようにしてもよい。   As shown in FIG. 7, a plurality of ribs 12Ac may be provided, the height of the ribs 12Ac may be changed, and the ribs may be formed on the foamed member.

本実施形態の天井埋込形空気調和機によれば、駆動手段への冷気進入を阻止し、ルーバ駆動手段への結露を防止できる天井埋込形空気調和機が実現する。   According to the ceiling-embedded air conditioner of the present embodiment, a ceiling-embedded air conditioner that prevents cold air from entering the drive means and prevents condensation on the louver drive means is realized.
