産業上の利用分野
本発明は、天井埋込型冷暖房空調機における、運転時の
送風音の低減を目的とした、天井埋込型冷暖房空調機に
関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ceiling-mounted cooling/heating air conditioner whose purpose is to reduce air blowing noise during operation.
従来の技術
近年、天井埋込型冷暖房空調機は居室内の床を全く必要
としないため急速に需要がのびている。BACKGROUND OF THE INVENTION In recent years, the demand for ceiling-embedded air conditioning and heating air conditioners has been rapidly increasing because they do not require any floor space in the living room.
以下、図面を参照しながら一般的な天井埋込型冷暖房空
調機の一例について説明する。Hereinafter, an example of a general ceiling-mounted heating and cooling air conditioner will be described with reference to the drawings.
第５図及び第６図は従来の天井埋込型冷暖房空調機の横
滑を示す。FIGS. 5 and 6 show side slippage in conventional ceiling-embedded heating and cooling air conditioners.

皿５を吊りボルト８及び固定ナツト９で固定していた。In the figure, the inside of the indoor unit 6 is equipped with a heat exchanger 2, a fan 3, a fan morph 4, and a water tray 5 in the outer shell 1, and the water receiver was fixed with a hanging bolt 8 and a fixing nut 9.
さらに室内側に突出しているパネル１０は、室内ユニッ
ト６から吊り下げられている吊りボルト８を介して蝶ネ
ジ１１で吊り下げ固定されている。また固定ナンド９と
蝶ネジ１１の内径は同一である。Further, the panel 10 protruding toward the indoor side is suspended and fixed by thumbscrews 11 via hanging bolts 8 suspended from the indoor unit 6. Furthermore, the inner diameters of the fixing pad 9 and thumbscrew 11 are the same.
発明が解決しようとする問題点
しかし、このような構造のものでは、運転をする際に、

かつそのホルト８の直径が１０ａ＋ｍと太いために抵抗
となり、矢印のごとく風の流れが乱れて異常な音が発生
し、さらに風量の低下もみられた。Problems to be solved by the invention However, with this type of structure, when driving,
As shown in FIG. 5, a voltage is applied to the fan motor 4 to rotate the fan 3, and as shown by the arrow, air flows from the room through the center of the panel 10, enters the indoor unit 6, and is absorbed by the heat exchanger 2. , cooling is performed from the Suita outlet 12, but when the fan 3 rotates as shown by the broken line as shown in FIG.
In addition, the diameter of the Holt 8 was as large as 10 a+m, which created resistance, disrupting the flow of air as shown by the arrow, producing abnormal noise, and further reducing the air volume.

いという問題点を有していた。During maintenance, this hanging bolt 8 also serves to fix both the water tray 5 and the panel 1o.
When removing the water tray, first remove the thumbscrews 11, remove the panel 1o from the indoor unit 6, and then remove the fixing bolts 9.
Since the inner diameter is the same as that of 1, when removing the fixing bolt 9, an equally long threaded portion must be removed. This has the problem that since the indoor unit 1 is embedded in the ceiling, the worker has to work in an upward posture for a long time, resulting in very poor workability.
本発明は上記問題点に＠み、運転時での送風音の低減を
目的とした天井埋込型冷暖房空調機を提供するものであ

れを防げることなくスムーズに流れる。At this time, when the fan 3 rotates in the direction of the dashed arrow as shown in FIG. 2, the air flows from the fan 3 to the heat exchanger 2 radially in a circular arc as shown by the solid arrow. Here, the rectifying part 13d of the hanging fitting 13 is fixed in the same direction as the wind flow, and as shown in FIGS. 3 and 4, the rectifying part 13d
Since d is an arc of about 100 degrees, the air flows smoothly without being blocked.

に行える。Therefore, since the flow is not disturbed, no abnormal noise is generated and no decrease in air volume is observed. Also, in Figure 1, the hanging bracket 13
Since only the water tray 5 is fixed with screws 15Vc via the fixing plate 14, when removing the water tray during maintenance, remove the panel 10 with the butterfly bolts 16 and use a tool such as a screwdriver to remove the panel 10. Since the screws 15 can be removed in a short time, the worker does not have to look upward during the work for a long time, resulting in good work efficiency. Furthermore, the fixing of the outer shell 1 and this hanging fitting 13 is also carried out using the fixing piece 1 of the hanging fitting 13.
3a can be easily done by using a cutter provided on the outer shell 1 and screwed together.
