この発明では、前記筐体の底面に、前記吸込グリルの枠が係合する溝部を設けたため、例えば、吸込グリルの枠が反った状態となったとしても、吸込グリルの枠の隙間がほとんどシールされ、従って、運転中に室内空気が吸込グリルを経ずに室内熱交換器の吸い込み空間に進入することが抑制される。また、吸込グリルの枠と溝部の嵌合であるため、一応のラビリンス効果が得られ、運転中に室内空気が吸込グリルを経ずに室内熱交換器の吸い込み空間に進入することが抑制される。 In order to solve the above-described problems, the present invention provides a ceiling-suspended air conditioner having a suction grill on the bottom surface of a housing housing an indoor heat exchanger and a blower, and a frame of the suction grill on the bottom surface of the housing. It is characterized in that a groove portion is provided to engage with.
In the present invention, since the groove portion for engaging the suction grille frame is provided on the bottom surface of the housing, for example, even if the suction grille frame is warped, the gap of the suction grille frame is almost sealed. Therefore, during operation, room air is prevented from entering the suction space of the indoor heat exchanger without passing through the suction grille. In addition, since the frame of the suction grille and the groove are fitted, a temporary labyrinth effect is obtained, and it is suppressed that the indoor air enters the suction space of the indoor heat exchanger without passing through the suction grille during operation. .

Further, the indoor air is prevented from entering the suction space of the indoor heat exchanger 15 without passing through the suction grille 37. Therefore, during operation, indoor dust is less likely to reach the indoor heat exchanger 15, and clogging of the indoor heat exchanger 15 is suppressed.

この構成では、閉塞板７１の下縁部７１Ｇは、吸込開口１２Ｃの縁部の一部を構成し、この下縁部７１Ｇには、吸込グリル３７の枠３７Ａが嵌る断面コ字状の溝部７１Ｈが形成されているため、吸込グリル３７の枠３７Ａが、閉塞板下縁部７１Ｇの断面コ字状の溝部７１Ｈに嵌り合うことで、吸込グリル３７の枠３７Ａと閉塞板下縁部７１Ｇとの間にほとんど隙間がなくなり、室内空気が室内熱交換器１５の吸い込み空間に進入することが抑制される。よって、運転中に、室内の塵埃が室内熱交換器１５に至ることが少なくなり、室内熱交換器１５の目詰まりが抑制される。   In this configuration, the lower edge portion 71G of the closing plate 71 constitutes a part of the edge portion of the suction opening 12C, and the lower edge portion 71G has a U-shaped groove portion 71H into which the frame 37A of the suction grille 37 fits. Since the frame 37A of the suction grille 37 fits into the U-shaped groove 71H of the closing plate lower edge 71G, the frame 37A of the suction grille 37 and the closing plate lower edge 71G There is almost no gap between them, and room air is prevented from entering the suction space of the indoor heat exchanger 15. Therefore, during operation, indoor dust is less likely to reach the indoor heat exchanger 15, and clogging of the indoor heat exchanger 15 is suppressed.

２枚の吸込グリル３７Ｒ，３７Ｌは、ケーシング１２Ａの両端に位置する各閉塞板７１の下縁部７１Ｇと、図３の後面側の支持片１００と、図３の前面側の支持片１０１と、開口中央部に位置する連結片１０２とに支持されて、取り付けられている。
中央部の連結片１０２は、断面コ字状で下が解放された溝部１０２Ａを有し、この溝部１０２Ａには、右の吸込グリル３７Ｒの枠３７Ａの左端部と、左の吸込グリル３７Ｌの枠３７Ａの右端部とが係合している。右の吸込グリル３７Ｒの枠３７Ａの右端部は、閉塞板７１の右の下縁部７１Ｇの溝部７１Ｈに係合し、左の吸込グリル３７Ｌの枠３７Ａの左端部は、左の下縁部７１Ｇの溝部７１Ｈに係合している。 In the present embodiment, the suction grille 37 is composed of two suction grilles 37R and 37L having the same width W1 and divided into left and right as schematically shown in FIG.
The two suction grilles 37R and 37L have the same shape.
The two suction grilles 37R and 37L include a lower edge 71G of each closing plate 71 located at both ends of the casing 12A, a support piece 100 on the rear side of FIG. 3, and a support piece 101 on the front side of FIG. It is supported and attached to the connecting piece 102 located at the center of the opening.
The central connecting piece 102 has a U-shaped groove portion 102A having a U-shaped cross section, and the groove portion 102A includes a left end portion of the frame 37A of the right suction grille 37R and a frame of the left suction grille 37L. The right end of 37A is engaged. The right end portion of the frame 37A of the right suction grille 37R is engaged with the groove portion 71H of the lower right edge portion 71G of the closing plate 71, and the left end portion of the frame 37A of the left suction grille 37L is left lower edge portion 71G. Is engaged with the groove 71H.

別実施の形態として、後面側、及び、前面側の支持片１００,１０１に対しても、断面コ字状で下が解放された溝部１００Ａ，１０１Ａを形成し、この溝部１００Ａ，１０１Ａに左右の吸込グリル３７Ｒ，３７Ｌの枠を係合する形態としてもよい。この構成では、２枚の吸込グリル３７Ｒ，３７Ｌの枠の略全周囲が、各溝部に係合するため、各係合部の間にほとんど隙間がなくなり、室内空気が室内熱交換器１５の吸い込み空間に進入することが抑制される。よって、運転中に、室内の塵埃が室内熱交換器１５に至ることが少なくなり、室内熱交換器１５の目詰まりが抑制される。   As another embodiment, groove portions 100A and 101A having a U-shaped cross section are formed on the rear side and front side support pieces 100 and 101, and left and right sides are formed in the groove portions 100A and 101A. It is good also as a form which engages the frame of suction grille 37R and 37L. In this configuration, since substantially the entire circumference of the frame of the two suction grilles 37R and 37L is engaged with each groove portion, there is almost no gap between each engagement portion, and the room air is sucked into the indoor heat exchanger 15. Entering the space is suppressed. Therefore, during operation, indoor dust is less likely to reach the indoor heat exchanger 15, and clogging of the indoor heat exchanger 15 is suppressed.

本実施の形態では、右の吸込グリル３７Ｒの枠の右端部が閉塞板７１の右の下縁部７１Ｇの溝部７１Ｈに係合し、左の吸込グリル３７Ｌの枠の左端部が左の下縁部７１Ｇの溝部７１Ｈに係合し、かつ中央部の連結片１０２の溝部１０２Ａには、右の吸込グリル３７Ｒの枠の左端部と、左の吸込グリル３７Ｌの枠の右端部とが係合するため、吸込グリル３７の枠３７Ａと下縁部７１Ｇ、及び中央部の連結片１０２との間にほとんど隙間がなくなり、室内空気が室内熱交換器１５の吸い込み空間に進入することが抑制される。よって、運転中に、室内の塵埃が室内熱交換器１５に至ることが少なくなり、室内熱交換器１５の目詰まりが抑制される。   In the present embodiment, the right end portion of the frame of the right suction grille 37R is engaged with the groove portion 71H of the right lower edge portion 71G of the closing plate 71, and the left end portion of the frame of the left suction grille 37L is the lower left edge. The left end portion of the frame of the right suction grille 37R and the right end portion of the frame of the left suction grille 37L engage with the groove portion 71H of the portion 71G and the groove portion 102A of the connecting piece 102 at the center portion. Therefore, there is almost no gap between the frame 37 </ b> A of the suction grille 37, the lower edge portion 71 </ b> G, and the connecting piece 102 at the center portion, and room air is prevented from entering the suction space of the indoor heat exchanger 15. Therefore, during operation, indoor dust is less likely to reach the indoor heat exchanger 15, and clogging of the indoor heat exchanger 15 is suppressed.

例えば、室内天井板５が経年変化等により波打った場合、サイドカバー４５の上面と、室内天井板５の下面との間に隙間が生じ、その隙間から室内空気をケーシング１２Ａの側面部１２Ｂに吸い込み、この側面部１２Ｂから、上述のように室内熱交換器１５の吸い込み空間に室内空気が進入する恐れがある。
本実施の形態では、上述したように、各部における隙間がほとんどなくなるため、運転中に、室内の塵埃が室内熱交換器１５に至ることが少なくなり、室内熱交換器１５の目詰まりが抑制される。 For example, when the indoor ceiling plate 5 undulates due to secular change or the like, a gap is generated between the upper surface of the side cover 45 and the lower surface of the indoor ceiling plate 5, and indoor air is passed from the gap to the side surface portion 12 </ b> B of the casing 12 </ b> A. Suction, there is a risk that room air may enter the suction space of the indoor heat exchanger 15 from the side surface portion 12B as described above.
In the present embodiment, as described above, since there are almost no gaps in each part, indoor dust is less likely to reach the indoor heat exchanger 15 during operation, and clogging of the indoor heat exchanger 15 is suppressed. The

以上、一実施の形態に基づいて、本発明を説明したが、本発明は、これに限定されるものではない。例えば、溝部７１Ｈ，１０２Ａを設ける部位は、吸込グリル３７に対応した位置で、ケーシング１２Ａの底面でよく、閉塞板７１の下縁部７１Ｇや、中央部の連結片１０２の下面に限定されない。   As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, the portion where the groove portions 71H and 102A are provided may be the bottom surface of the casing 12A at a position corresponding to the suction grille 37, and is not limited to the lower edge portion 71G of the closing plate 71 or the lower surface of the connecting piece 102 in the central portion.
