Description

本発明は、空気調和装置の室外機及びこの室外機を備えた空気調和装置に関するものである。   The present invention relates to an outdoor unit of an air conditioner and an air conditioner including the outdoor unit.

空気調和装置の室外機において、暖房運転中に雨や雪などによって前面パネルに付着した水滴や、室外機の上に積っている雪が融けた水滴が前面パネルの表面に沿って落下し、ベルマウスとファンの間に浸入する。
そして、外気温度が低い場合は、ファンの吹出し空気温度が氷点以下となることがあり、そのような場合はベルマウスとファンとの間に浸入した水滴が氷結し、水滴の量が多いと氷結した氷が成長してファンと接触し、異常音を発生したり、回転を妨げることにより室外機が異常停止するなどの問題が発生した。 In the outdoor unit of an air conditioner, water droplets that adhere to the front panel due to rain or snow during heating operation or water that melts snow on the outdoor unit fall along the surface of the front panel and drop Infiltrate between mouse and fan.
If the outside air temperature is low, the temperature of the blown air from the fan may be below the freezing point. In such a case, water droplets that enter between the bell mouth and the fan freeze, and if the amount of water droplets is large, the ice freezes. As the ice grows, it comes into contact with the fan, causing abnormal noise, and the outdoor unit stops abnormally by preventing rotation.

このような問題を解消するためにケーシングにファンの吹出し口を形成するベルマウスを設けると共に、その前面側に吹出しグリルを設け、吹出し口の上方に吹出し口の径以上の幅を有し、ケーシングと吹出し口との間をシールするシール部材を設けた空気調和機用室外機が提案されている（例えば、特許文献１参照）。   In order to solve such a problem, the casing is provided with a bell mouth that forms a fan outlet, a front grille is provided with a blow grill, and the casing has a width equal to or larger than the diameter of the outlet. There has been proposed an air conditioner outdoor unit provided with a seal member that seals between the air outlet and the outlet (for example, see Patent Document 1).

実用新案登録第２５１００７８号公報（第２頁、図１）Utility Model Registration No. 2510078 (2nd page, FIG. 1)

特許文献１の空気調和機用室外機は、ケーシングと吹出しグリルの上部の間をシール部材でシールする場合、鉄線を溶接した吹出しグリルの外周、少なくとも上辺において額縁状の縁が必要であり、外観意匠性を損うばかりでなく、鉄線部分に板状の部品を組合わせる必要があり、製造が面倒でコストの高くなるという問題があった。
また、シール部材は、吹出しグリルの両端部だけの固定では、中央部分のすき間を塞ぐことが難しいので固定ねじを増加することになるが、このため外観性、作業性が悪化するという問題点があった。 The outdoor unit for an air conditioner of Patent Document 1 requires a frame-like edge at the outer periphery, at least the upper side, of the blowout grill welded with iron wire when sealing between the casing and the upper part of the blowout grill with a sealing member. In addition to impairing the design, there is a problem that it is necessary to combine a plate-like part with the iron wire portion, which is troublesome to manufacture and high in cost.
Also, if the sealing member is fixed only at both ends of the blowout grill, it is difficult to close the gap in the central portion, so the number of fixing screws is increased, but this causes the problem that the appearance and workability deteriorate. there were.

さらに、前記のシール部材を固定する固定箇所を削減するために、シール部材の両端部のみを固定し、中間部を吹出しグリルの弾性を利用してケーシングに押し付けることで、ガタツキや振動を抑制するようにしている。しかし、この場合は、吹出しグリル自体の弾性によりたわんだ状態で両端部が固定されるため、ケーシングと吹出しグリルとの間をシールするシール部材が曲線状になり、確実にシールすることは困難である。   Furthermore, in order to reduce the number of fixing points for fixing the sealing member, only both ends of the sealing member are fixed, and the intermediate portion is pressed against the casing by using the elasticity of the blowout grill, thereby suppressing rattling and vibration. I am doing so. However, in this case, since both ends are fixed in a state of being bent due to the elasticity of the blowout grill itself, the seal member for sealing between the casing and the blowout grill has a curved shape, and it is difficult to reliably seal. is there.

また、シール部材は厚みと同程度の幅が必要なため、吹出しグリルの上面から１０ｍｍ以上下った位置に壁が出来ることになる。このため、製品サイズの小型化と性能改善のために、ファン径を最大限に設定する必要がある製品設計上、特に、吹出しグリルの上辺の中央部付近において、シール部材が風路側に突出してファンによる吹出しを阻害することになり、騒音の発生や空力性能の阻害要因になっていた。   Further, since the seal member needs to have a width approximately equal to the thickness, a wall is formed at a position 10 mm or more lower than the upper surface of the blowout grill. For this reason, in order to reduce the product size and improve the performance, it is necessary to set the fan diameter to the maximum, especially in the vicinity of the center of the upper side of the blow grill, the seal member protrudes toward the air channel side. As a result, the blowout by the fan was hindered, and this was an obstacle to the generation of noise and aerodynamic performance.

本発明は、上記の課題を解決するためになされたもので、簡単な構造でベルマウスとプロペラファンとの間で水滴が氷結するのを確実に防止することのできる室外機及びこの室外機を備えた空気調和装置を提供することを目的としたものである。   The present invention has been made to solve the above-described problems, and an outdoor unit that can reliably prevent water droplets from icing between a bell mouth and a propeller fan with a simple structure, and the outdoor unit. An object of the present invention is to provide an air conditioner provided.

本発明に係る室外機は、上部が開口されたほぼ直方体状のケーシングと、該ケーシングの上部開口部を閉塞する天面パネルとを有し、前記ケーシングを構成する前面パネルに形成されたプロペラファンの吹出し口にベルマウスが設けられ、前記吹出し口の前面側に吹出しグリルが取付けられた室外機において、前記天面パネルの前面側の前記吹出しグリルに対応する部分の縁部に、該縁部から前面側に張り出した庇部を設け、前記庇部の前端部の下部を内側に折り曲げて折り曲げ部を形成したものである。 An outdoor unit according to the present invention includes a substantially rectangular parallelepiped casing having an upper opening, and a top panel that closes the upper opening of the casing, and a propeller fan formed on a front panel constituting the casing. In an outdoor unit in which a bell mouth is provided at the air outlet of the air outlet, and an air outlet grill is attached to the front side of the air outlet, the edge portion of the top panel corresponding to the air outlet grill on the front side of the top panel A flange that projects from the front to the front side is provided , and a lower portion of the front end of the flange is bent inward to form a bent portion .

また、本発明に係る空気調和装置は、上記の室外機を備えたものである。   Moreover, the air conditioning apparatus which concerns on this invention is equipped with said outdoor unit.

本発明によれば、簡単な構造で外観性を損うことがなく、ベルマウスとプロペラファンとの間で水滴が氷結するのを確実に防止することのできる室外機及びこれを備えた空気調和装置を得ることができる。   According to the present invention, an outdoor unit capable of reliably preventing water droplets from icing between the bell mouth and the propeller fan without damaging the appearance with a simple structure, and an air conditioner including the same. A device can be obtained.

1 is an external perspective view of an outdoor unit of an air-conditioning apparatus according to Embodiment 1 of the present invention, FIG. 2 is a perspective view showing a state in which the top panel of FIG. 1 is removed, and FIG. 3 is an obliquely opposite side of FIG. FIG. 4 is a top view of FIG. 1. In the following description, the front side of the figure is referred to as the front side, the back side as the back side, the left side as the left side, and the right side as the right side.

図１〜図４において、１は室外機のケーシングで、下面に脚部２ａを有する底板、前面側から左側面にかけて設置されたほぼＬ字状の前面パネル３、右側面から背面側の一部にかけて設置された側面パネル４及び背面側から左側面の前面パネル３の内側にかけて設置されたほぼＬ字状の熱交換器５により、上面が開口された直方体状に形成されており、上面開口部は天面パネル１５により閉塞されている。なお、ケーシング１内には、仕切り板、圧縮機、冷媒配管、電気品などが搭載されているが、図示してない。   1-4, 1 is a casing of an outdoor unit, a bottom plate having a leg portion 2a on the lower surface, a substantially L-shaped front panel 3 installed from the front side to the left side, a part from the right side to the rear side Are formed in a rectangular parallelepiped shape whose upper surface is opened by a side panel 4 installed over and a substantially L-shaped heat exchanger 5 installed from the back side to the inside of the front panel 3 on the left side. Is closed by the top panel 15. In addition, although the partition plate, the compressor, the refrigerant piping, the electrical component, and the like are mounted in the casing 1, they are not illustrated.

３０はその駆動モータ（図示せず）がケーシング１内において底板２に立設されたモータ取付板６に取り付けられたプロペラファンで、前面パネル３に設けたプロペラファン３０の吹出し口にはベルマウス７が設けられており、吹出し口の外側には、吹出し口を覆って吹出しグリル８が取付けられている。
そして、前面パネル３及び側面パネル４の上端部には、段部９ａを介して僅かに縮小された係合部９が形成されており、後述の天面パネル１５の嵌合部１８に設けねじ挿通穴１９に対応してねじ穴１０が設けられている。 A propeller fan 30 is attached to a motor mounting plate 6 whose drive motor (not shown) is erected on the bottom plate 2 in the casing 1, and a bell mouth is provided at the outlet of the propeller fan 30 provided on the front panel 3. 7 is provided, and a blowout grill 8 is attached outside the blowout opening so as to cover the blowout opening.
And the engagement part 9 slightly reduced via the step part 9a is formed in the upper end part of the front panel 3 and the side panel 4, and it is provided in the fitting part 18 of the top | upper surface panel 15 mentioned later. A screw hole 10 is provided corresponding to the insertion hole 19.

天面パネル１５はケーシング１の外形とほぼ等しい大きさに形成され、周縁には後述の庇部１６を除き、ケーシング１の係合部９に嵌合する嵌合部１８が設けられており、前面側の吹出しグリル８に対応する部分は、縁部から外方（前面側）に張り出した庇部１６が設けられている。実施例では、この庇部１６の張り出し量を縁部から１０〜２０ｍｍ程度としたが、これに限定するものではない。そして、嵌合部１８には、庇部１６の近傍を含めて複数のねじ挿通穴１９が設けられている。   The top panel 15 is formed to have a size substantially equal to the outer shape of the casing 1, and a fitting portion 18 that is fitted to the engaging portion 9 of the casing 1 is provided on the periphery except for a flange portion 16 described later. A portion corresponding to the front grille grill 8 is provided with a flange 16 projecting outward (front side) from the edge. In the embodiment, the protruding amount of the flange portion 16 is about 10 to 20 mm from the edge portion, but is not limited thereto. The fitting portion 18 is provided with a plurality of screw insertion holes 19 including the vicinity of the flange portion 16.

この庇部１６は、図５のＸ−Ｘ断面図である図６（ａ），（ｂ）に示すように、前端部の下部が内側にほぼＵ字状に折り曲げられ、又は内側に向ってカールされている（以下、この部分を折り曲げ部１７という）。
また、図３、図４に示すように、天面パネル１５の庇部１６に続く左側面の縁部は、段部２１を介して庇部１６の左端部の面より僅かに張り出して（例えば、数ｍｍ〜１０ｍｍ程度）、張り出し部２０が形成されている。なお、ケーシング１の前面パネル３の側面部３ａも、段部１１を介して天面パネル１５の張り出し部２０に対応した形状になっている。 As shown in FIGS. 6 (a) and 6 (b) which are XX cross-sectional views of FIG. 5, the flange portion 16 is bent in a substantially U-shape at the lower end of the front end portion, or toward the inside. It is curled (hereinafter, this portion is referred to as a bent portion 17).
Further, as shown in FIGS. 3 and 4, the edge of the left side surface following the flange 16 of the top panel 15 slightly protrudes from the left end surface of the flange 16 via the stepped portion 21 (for example, , A few mm to about 10 mm), and the overhanging portion 20 is formed. Note that the side surface portion 3 a of the front panel 3 of the casing 1 also has a shape corresponding to the protruding portion 20 of the top panel 15 via the step portion 11.

このように構成した天面パネル１５は、その嵌合部１８をケーシング１の係合部９に嵌合してケーシング１の上部開口部を閉塞し、天面パネル１５の嵌合部１８に設けた複数のねじ挿通穴１９に挿通したねじを、このねじ挿通穴１９に対応してケーシング１の係合部９に設けたねじ穴１０にそれぞれ螺入し、一体に固定する。このとき、天面パネル１５に設けた庇部１６は、吹出しグリル８の上方において前面パネル３の表面から、前面側にほぼ吹出しグリル８の前縁部の近傍まで突出する。   The top panel 15 configured as described above is provided in the fitting portion 18 of the top panel 15 by fitting the fitting portion 18 to the engaging portion 9 of the casing 1 to close the upper opening of the casing 1. The screws inserted into the plurality of screw insertion holes 19 are respectively screwed into the screw holes 10 provided in the engaging portions 9 of the casing 1 corresponding to the screw insertion holes 19 and fixed integrally. At this time, the flange 16 provided on the top panel 15 protrudes from the surface of the front panel 3 above the blow grill 8 to the front side to the vicinity of the front edge of the blow grill 8.

この場合、吹出しグリル８がケーシング１の左側に位置するため、天面パネル１５はその左側の縁部と、庇部１６の左側の端面とが同一平面になり、この部分が直線状になっていると、製品組立時に天面パネル１５が前後方向にずれて、ねじ挿通穴１９とねじ穴１０が整合せず、作業性が悪くなるおそれがある。   In this case, since the blow-out grill 8 is located on the left side of the casing 1, the left side edge of the top panel 15 and the left end face of the flange 16 are flush with each other, and this portion is straight. When the product is assembled, the top panel 15 is displaced in the front-rear direction, the screw insertion hole 19 and the screw hole 10 are not aligned, and workability may be deteriorated.

本実施の形態においては、天面パネル１６の左側の縁部を、庇部１６の左側の端面との間に設けた段部２０ａを介して若干張り出した張り出し部２０を形成し、ケーシング１の前面パネル３の側面３ａも段部１１ａを介して張り出し部２０に対応した形状に形成したので、組立時に天面パネル１５の前後方向の位置決めを確実に行うことができ、作業性を向上することができる。   In the present embodiment, a protruding portion 20 is formed by slightly projecting the left edge of the top panel 16 via a step portion 20 a provided between the left end surface of the flange portion 16 and the casing 1. Since the side surface 3a of the front panel 3 is also formed in a shape corresponding to the projecting portion 20 through the stepped portion 11a, the top panel 15 can be reliably positioned in the front-rear direction during assembly, and workability is improved. Can do.

上記のように構成した本実施の形態に係る室外機においては、天面パネル１５の上に付着した水滴や、天面パネル１５上に積った雪が融けて前面側に流れ出した場合、図の右側においては前面パネル３に沿って流れ落ちるが、吹出しグリル８側（左側）においては天面パネル１５に庇部１６が設けられているため、前面パネル３の面から離れた位置に水滴が落下し、前面パネル３の下部又は吹出しグリル８の棧に接触し、棧に沿って落下する。このため、凍結によるつららは吹出しグリル８の棧の部分で成長し、前面パネル３及びベルマウス７内へは浸入しない。   In the outdoor unit according to the present embodiment configured as described above, when water droplets adhering to the top panel 15 or snow accumulated on the top panel 15 melt and flow to the front side, Although it flows down along the front panel 3 on the right side, since the flange 16 is provided on the top panel 15 on the blowing grill 8 side (left side), water drops fall away from the surface of the front panel 3. Then, it touches the lower part of the front panel 3 or the ridge of the blowout grill 8 and falls along the ridge. For this reason, icicles due to freezing grow at the ridge portion of the blowout grill 8 and do not enter the front panel 3 and the bell mouth 7.

このため、外気温度が低くなってプロペラファン３０からの吹出し空気温度が氷点以下になっても、ベルマウス７とプロペラファン３０との間に氷結が生じることがなく、氷結によるプロペラファン３０の異常音の発生を防止することができる。   For this reason, even if the outside air temperature becomes low and the temperature of the air blown from the propeller fan 30 falls below the freezing point, no ice formation occurs between the bell mouth 7 and the propeller fan 30, and the abnormality of the propeller fan 30 due to freezing. Generation of sound can be prevented.

また、天面パネル１５の庇部１６は、その前端部が前面パネル３から離れた位置（突出した位置）にあるため、庇部１６に指をかけることがあるが、庇部１６の先端部の下部には内側に折り曲げた折り曲げ部１７を設けたので、指に怪我をすることがなく、安全性を確保することができる。
また、天面パネル１５は、庇部１６の近傍を含む嵌合部１８の複数箇所に設けたねじ挿通穴１９に挿通したねじを、これに対応してケーシング１の係合部９に設けたねじ穴１０に螺入して固定したので、若し、庇部１６に手を掛けて持ち上げるような力が加えられても、天面パネル１６の変形を防止することができる。 Further, since the front end portion of the top panel 15 is located at a position away from the front panel 3 (projected position), a finger may be put on the top portion 16. Since the bent portion 17 that is bent inward is provided at the lower portion of the finger, the finger is not injured and safety can be ensured.
Further, the top panel 15 is provided with the screws inserted into the screw insertion holes 19 provided at a plurality of locations of the fitting portion 18 including the vicinity of the flange portion 16 in the engaging portion 9 of the casing 1 correspondingly. Since the screw hole 10 is screwed and fixed, the top panel 16 can be prevented from being deformed even if a force such as placing the hand on the collar 16 and lifting it is applied.
