Description

本発明は、空気調和機、特に、前面パネルを取り外したり取り付けたりすることのできる空気調和機に関する。   The present invention relates to an air conditioner, and more particularly to an air conditioner from which a front panel can be removed or attached.

従来から、空気調和機の中には、特許文献1(特開2012−24714号公報)に記載されているように、前面パネルが着脱可能に構成されているものがある。空気調和機のメンテナンス時などに前面パネルを取り外すと、前面パネルのみが取り扱い中に落下して、前面パネルの落下衝撃で前面パネルに割れが生じることがある。そこで、一般的に、前面パネルについては、人が通常前面パネルを取り扱う程度の高さから落下しても割れが生じ難いように設計される。   Conventionally, some air conditioners have a front panel configured to be detachable as described in Patent Document 1 (Japanese Patent Laid-Open No. 2012-24714). If the front panel is removed during maintenance of the air conditioner, etc., only the front panel may fall during handling, and the front panel may be cracked by the drop impact of the front panel. Therefore, in general, the front panel is designed so that cracking does not easily occur even if a person falls from a height that normally handles the front panel.

しかしながら、前面パネルは、空気調和機の中でもデザイン的に最も重要な位置である前面に配置される。デザインを重視した場合には、前面パネルが落下衝撃で割れを生じ易い形状になることがある。特に、前面パネルの角部は落下時に床などに衝突しやすく、割れを生じ易い部分である。角部の境界部分の曲率半径が大きなデザインの前面パネル、例えば、特許文献1に記載されている前面パネルでは割れが生じにくいが、角部の曲率半径を小さく設計すると前面パネルの角部で割れが発生し易くなる。   However, the front panel is disposed on the front surface, which is the most important design position among the air conditioners. If the design is emphasized, the front panel may be easily cracked by a drop impact. In particular, the corner portion of the front panel is a portion that easily collides with the floor or the like when dropped, and easily cracks. A front panel with a large radius of curvature at the corner boundary, for example, the front panel described in Patent Document 1, is less likely to crack, but if the corner radius of curvature is designed to be small, it is cracked at the corner of the front panel. Is likely to occur.

The front panel 30 is shown in FIGS. 2 to 11, the state seen from the front is shown in FIG. 4, the state seen from the left is shown in FIG. 5, the state seen from above is the state seen from below in FIG. 7 is shown in FIG. 7, and the state seen from behind is shown in FIG. 4 to 8 show the front panel 30 in a state before the decorative resin panel 80 is pasted. Further, FIG. 9 shows a cross section taken along line II in FIG. 8, FIG. 10 shows a cross section taken along line II-II in FIG. 8, and FIG. 8 shows a cross section taken along line III-III in FIG. 11. In the description here, the front and rear (front direction and back direction), left and right, and top and bottom of the air purifier 10 are directions indicated by arrows in FIG.

前面パネル30は、前面部31と上側面部32と下側面部33と右側面部34と左側面部35とが一体的に成形されてなる。前面パネル30は樹脂製である。前面パネル30に用いられる樹脂としては、例えば熱可塑性樹脂があり、熱可塑性樹脂としては例えば耐衝撃性ポリエチレン(HIPS:High Impact Polystyrene)又はアクリロニトリル・ブタジエン・スチレン樹脂(ABS樹脂)がある。前面パネル30は、例えば射出成形により成形され、前面部31と上側面部32と下側面部33と右側面部34と左側面部35とが同時に成形される。   The front panel 30 is formed by integrally forming a front surface portion 31, an upper side surface portion 32, a lower side surface portion 33, a right side surface portion 34, and a left side surface portion 35. The front panel 30 is made of resin. Examples of the resin used for the front panel 30 include a thermoplastic resin, and examples of the thermoplastic resin include impact-resistant polyethylene (HIPS) or acrylonitrile-butadiene-styrene resin (ABS resin). The front panel 30 is formed by, for example, injection molding, and the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, and the left side surface portion 35 are simultaneously formed.

前面部31と上側面部32と下側面部33と右側面部34と左側面部35は、板状であり、前面部31と上側面部32と下側面部33と右側面部34と左側面部35の板厚は、1〜5mmの範囲内で適切な値に設定されている。前面部31と上側面部32と下側面部33と右側面部34と左側面部35の板厚は例えば全て同じに設定され、例えば2mmである。   The front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34 and the left side surface portion 35 are plate-shaped, and the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34 and the left side surface portion 35. The plate thickness is set to an appropriate value within a range of 1 to 5 mm. The plate thicknesses of the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, and the left side surface portion 35 are all set to the same, for example, 2 mm, for example.

前面パネル30は、本体20に前面パネル30を固定するために、本体20の上面に引っ掛ける突起71が上側面部32の下面32aから下方に突出している。また、本体20に前面パネル30を固定するために、右側面部34と左側面部35の下方にロック機構74,75がそれぞれ設けられている。上側面部32の突起71を本体20の上面に引っ掛け、前面パネル30の下方を本体20の側に押し込むことにより、前面パネル30の下方がロック機構74,75でロックされて前面パネル30が固定される。   In the front panel 30, a protrusion 71 that hooks on the upper surface of the main body 20 protrudes downward from the lower surface 32 a of the upper side surface portion 32 in order to fix the front panel 30 to the main body 20. Further, in order to fix the front panel 30 to the main body 20, lock mechanisms 74 and 75 are provided below the right side surface portion 34 and the left side surface portion 35, respectively. By hooking the protrusion 71 of the upper side surface portion 32 on the upper surface of the main body 20 and pushing the lower portion of the front panel 30 toward the main body 20, the lower portion of the front panel 30 is locked by the lock mechanisms 74 and 75 and the front panel 30 is fixed. Is done.

前面パネル30は、上側面部32、下側面部33、右側面部34及び左側面部35と前面部31とは接続部40で接続されている。接続部40は、例えば、上側面部32及び前面部31に垂直な平面で切断したときの断面が、例えば3mm以上8mm以下の半径を有する円弧状の形状を呈する。前面パネル30は、上側面部32と右側面部34とが境界曲面部36で接続され、上側面部32と右側面部34とが境界曲面部37で接続され、下側面部33と右側面部34とが境界曲面部38で接続され、下側面部33と左側面部35とが境界曲面部39で接続されている。これら境界曲面部36〜39は、前面部31に略平行な平面で切断したときの形状が円弧状になっている。境界曲面部36〜39の半径は、例えば4mm以下に設定されている。例えば、この境界曲面部36〜39の半径は約3mmである。その結果、前面パネル30は、上側面部32と右側面部34、上側面部32と右側面部34、下側面部33と右側面部34、下側面部33と左側面部35の境界がはっきりとしたシャープな輪郭を呈する。しかし、境界曲面部36,37の曲率半径が小さくなると曲率半径が大きい場合に比べて、右側上部の角部51及び左側上部の角部51が落下したときに床面に衝突すると角部51,52の周辺で割れが生じ易くなる。そこで、角部51,52に凹部61,62が形成されている。   In the front panel 30, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, the left side surface portion 35, and the front surface portion 31 are connected by a connection portion 40. For example, the connection portion 40 has an arc shape in which a cross section when cut by a plane perpendicular to the upper side surface portion 32 and the front surface portion 31 has a radius of, for example, 3 mm or more and 8 mm or less. In the front panel 30, the upper side surface portion 32 and the right side surface portion 34 are connected by a boundary curved surface portion 36, the upper side surface portion 32 and the right side surface portion 34 are connected by a boundary curved surface portion 37, and the lower side surface portion 33 and the right side surface portion 34 are connected. Are connected by a boundary curved surface portion 38, and the lower side surface portion 33 and the left side surface portion 35 are connected by a boundary curved surface portion 39. These boundary curved surface portions 36 to 39 are arcuate when cut along a plane substantially parallel to the front surface portion 31. The radius of the boundary curved surface portions 36 to 39 is set to 4 mm or less, for example. For example, the radius of the boundary curved surface portions 36 to 39 is about 3 mm. As a result, the front panel 30 has a sharp boundary between the upper side surface portion 32 and the right side surface portion 34, the upper side surface portion 32 and the right side surface portion 34, the lower side surface portion 33 and the right side surface portion 34, and the lower side surface portion 33 and the left side surface portion 35. Presents a beautiful outline. However, when the curvature radius of the boundary curved surface portions 36 and 37 is reduced, the corner portion 51 and the corner portion 51 when the corner portion 51 on the right upper side and the corner portion 51 on the left upper portion collide with the floor surface when the corner portion 51 on the right side falls are compared with the case where the radius of curvature is large. Cracks are likely to occur around 52. Therefore, concave portions 61 and 62 are formed in the corner portions 51 and 52.

これら凹部61,62は、前面部31の左右方向の中央において上下に延びる前面部31に垂直な平面に対して互いに面対称に形成されている。以下においては、凹部61の形状について詳細に説明し、凹部61と面対称な凹部62の形状についての詳しい説明を省略する。凹部61は、図11に示されているように、深さDp1が2mm以上あり、3mm以上であることが好ましい。前面部31の角部51からは境界曲面部36が後方に延びている。この角部51においては、境界曲面部36に接する第1側面部が上側面部32であり、境界曲面部36に接する第2側面部が右側面部34である。なお、角部52からは境界曲面部37が後方に延びている。この角部52においては、境界曲面部37に接する第1側面部が上側面部32であり、境界曲面部37に接する第2側面部が左側面部35である。   The concave portions 61 and 62 are formed symmetrically with respect to a plane perpendicular to the front surface portion 31 extending vertically in the center of the front surface portion 31 in the left-right direction. Below, the shape of the recessed part 61 is demonstrated in detail, and the detailed description about the shape of the recessed part 62 symmetrical to the recessed part 61 is abbreviate | omitted. As shown in FIG. 11, the recess 61 has a depth Dp1 of 2 mm or more and preferably 3 mm or more. A boundary curved surface portion 36 extends rearward from the corner portion 51 of the front surface portion 31. In the corner portion 51, the first side surface portion in contact with the boundary curved surface portion 36 is the upper side surface portion 32, and the second side surface portion in contact with the boundary curved surface portion 36 is the right side surface portion 34. The boundary curved surface portion 37 extends rearward from the corner portion 52. In the corner portion 52, the first side surface portion in contact with the boundary curved surface portion 37 is the upper side surface portion 32, and the second side surface portion in contact with the boundary curved surface portion 37 is the left side surface portion 35.

図11に示されているように、凹部61の深さDp1は、境界曲面部36の前端部36aから後部に向かって、2mmの範囲には前面部31の支持が無いことを意味する。前面部31に支持されない2mmの境界曲面部36は、上側面部32及び右側面部34によってのみ支えられているから、凹部61の周囲の境界曲面部36、上側面部32及び右側面部34が構成する凹部61の壁は、境界曲面部36の一部、上側面部32の一部及び右側面部34の一部に落下衝撃を受けたときに、従来のように前面部31に前端部36aなどで接続されている場合に比べて撓みやすくなっている。樹脂でできている凹部61のこれらの壁は、撓みによる変形が樹脂の弾性変形であれば衝撃がなくなると元に戻る。その結果、凹部61のこれらの壁によって角部51の周辺、特に境界曲面部36の前端部36aの周辺が床面に衝突した時に凹部61の壁が撓んで落下衝撃を吸収することができ且つ角部51の周辺の外観を衝突前の状態に維持することができる。凹部61の深さDp1が2mmより浅いと凹部61の壁が撓みにくくなる。   As shown in FIG. 11, the depth Dp1 of the recess 61 means that the front surface portion 31 is not supported in a range of 2 mm from the front end portion 36a of the boundary curved surface portion 36 toward the rear portion. Since the 2 mm boundary curved surface portion 36 that is not supported by the front surface portion 31 is supported only by the upper side surface portion 32 and the right side surface portion 34, the boundary curved surface portion 36, the upper side surface portion 32, and the right side surface portion 34 around the recess 61 are configured. The wall of the concave portion 61 is formed such that when a drop impact is applied to a part of the boundary curved surface part 36, a part of the upper side part 32, and a part of the right side part 34, the front end part 36a or the like is provided on the front part 31 as in the prior art. It is easier to bend than when connected by. These walls of the recess 61 made of resin return to their original state when the impact is eliminated if the deformation due to the bending is an elastic deformation of the resin. As a result, these walls of the recess 61 can absorb the drop impact by bending the wall of the recess 61 when the periphery of the corner 51, particularly the periphery of the front end portion 36a of the boundary curved surface portion 36 collides with the floor surface. The appearance around the corner 51 can be maintained in the state before the collision. When the depth Dp1 of the recess 61 is shallower than 2 mm, the wall of the recess 61 is difficult to bend.

(2−2)化粧樹脂パネル
前面パネル30には、前面パネル30の上部に表示用の複数の開口部45が設けられている。これら開口部45から内部に塵埃や水などが入らないように、透明な化粧樹脂パネル80がこれら開口部45を覆うように前面パネル30の上部に取り付けられている。透明な化粧樹脂パネル80は、透明な樹脂からなる例えば厚さ2mm以上5mm以下の板状の部材である。前面パネル30には、化粧樹脂パネル80を取り付けるための段差46が設けられている(図5参照)。
(2-2) Cosmetic resin panel The front panel 30 is provided with a plurality of display openings 45 at the top of the front panel 30. A transparent decorative resin panel 80 is attached to the upper portion of the front panel 30 so as to cover these openings 45 so that dust and water do not enter the openings 45 from the inside. The transparent decorative resin panel 80 is a plate-shaped member made of a transparent resin and having a thickness of 2 mm or more and 5 mm or less, for example. The front panel 30 is provided with a step 46 for attaching the decorative resin panel 80 (see FIG. 5).

図12には、図11に示されている箇所の前面パネル30と化粧樹脂パネル80との関係が示されている。化粧樹脂パネル80は、例えば接着剤又は粘着剤で前面パネル30の前面部31の前側に貼着される。しかし、化粧樹脂パネル80は、図12に示されているように、境界曲面部36うちの凹部61の壁を形成する部分には接続されない。境界曲面部36うちの凹部61の壁を形成する部分を言い換えると、凹部61の壁を形成する境界曲面部36の一部ということになる。例えば、化粧樹脂パネル80が境界曲面部36の前端部36aに接続されていると、角部51の周辺が床面に衝突したときの落下衝撃が化粧樹脂パネル80に伝わるため、化粧樹脂パネル80に割れや白化が生じたり、化粧樹脂パネル80から前面パネル30の衝撃が伝播して前面パネル30に割れが生じたりする場合がある。ここで白化とは、樹脂が白く変色することをいう。従って、化粧樹脂パネル80が凹部61の壁を形成する境界曲面部36の一部から離して取り付けられていることで、化粧樹脂パネル80及び前面パネル30の割れや白化を防止することができる。同様に、化粧樹脂パネル80は、上側面部32うちの凹部61の壁を形成する部分及び右側面部34うちの凹部61の壁を形成する部分には接続されない。言い換えると、凹部61の壁を形成する上側面部32の一部及び右側面部34の一部に化粧樹脂パネル80は貼着されない。   FIG. 12 shows the relationship between the front panel 30 and the decorative resin panel 80 at the location shown in FIG. The decorative resin panel 80 is attached to the front side of the front portion 31 of the front panel 30 with, for example, an adhesive or an adhesive. However, as shown in FIG. 12, the decorative resin panel 80 is not connected to a portion of the boundary curved surface portion 36 that forms the wall of the recess 61. In other words, the portion of the boundary curved surface portion 36 that forms the wall of the recess 61 is a part of the boundary curved surface portion 36 that forms the wall of the recess 61. For example, when the decorative resin panel 80 is connected to the front end portion 36a of the boundary curved surface portion 36, a drop impact is transmitted to the decorative resin panel 80 when the periphery of the corner 51 collides with the floor surface. May be cracked or whitened, or the impact of the front panel 30 may propagate from the decorative resin panel 80 to cause the front panel 30 to crack. Here, whitening means that the resin turns white. Therefore, the decorative resin panel 80 is mounted apart from a part of the boundary curved surface portion 36 that forms the wall of the recess 61, so that the decorative resin panel 80 and the front panel 30 can be prevented from being cracked or whitened. Similarly, the decorative resin panel 80 is not connected to the portion of the upper side surface portion 32 that forms the wall of the recess 61 and the portion of the right side surface portion 34 that forms the wall of the recess 61. In other words, the decorative resin panel 80 is not attached to a part of the upper side surface part 32 and a part of the right side surface part 34 forming the wall of the recess 61.
