発明が解決しようとする問題点
しかし、第６図の構造のものでは前面グリル１
０６とフアンガード１０７が一体成型されていな
いため、部品点数が増えかつ意匠的にフアンガー
ドが見立つて美観をそこなうと云う問題点を有し
ていた。Problems to be Solved by the Invention However, in the structure shown in Fig. 6, the front grill 1
Since 06 and the fan guard 107 are not integrally molded, there are problems in that the number of parts increases and the fan guard stands out from the design, detracting from the aesthetics.
また、第７図、第８図、第９図の構造のもので
は前面グリル本体２０６をフアンガード２０６ａ
と一体成型することにより部品点数が減り、かつ
意匠的にも美観をそこなわないので、上記第６図
の構造のものについての問題点を解消できる。 In addition, in the structures shown in FIGS. 7, 8, and 9, the front grill body 206 is replaced by a fan guard 206a.
Since integral molding reduces the number of parts and does not impair the aesthetic appearance, the problems associated with the structure shown in FIG. 6 can be solved.
ところが、第７図、第８図、第９図ではフアン

た。 However, in FIGS. 7, 8, and 9, when the fan 207 rotates and blows air, the fan guard 206
Part of the wind that hits the front grill body 206 passes through the front grill body 206, but part of it hits the fan orifice 206b, and the wind that has no place to escape there generates turbulence as shown by the arrow. As a result, flow resistance increases, leading to problems such as a decrease in air volume and an increase in noise.
本発明は上記問題点に鑑み、フアンガードに当
つた風がスムーズに流れ、風量ダウンおよび騒音
の増大とすることなく、空気調和ができるように
するものである。 In view of the above-mentioned problems, the present invention allows air to flow smoothly when it hits the fan guard, thereby achieving air conditioning without reducing the air volume or increasing noise.
問題点を解決するための手段
上記問題点を解決する本発明の技術的な手段
は、フアンオリフイスの形状を円周方向に傾斜し
て段を設けたものである。Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide a fan orifice with steps inclined in the circumferential direction.
作 用 この技術的手段による作用は次のようになる。Effect The effect of this technical means is as follows.
すなわち、フアンガードに当つた風の一部は従
来例と同様前面グリル本体をスムーズに通過し、
一部はフアンオリフイスが傾斜していることによ
り、その傾斜にそつて風が流れ前面グリル本体を
スムーズに通過するようになる。 In other words, part of the wind that hits the fan guard passes smoothly through the front grill body, just like in the conventional example.
Partly because the fan orifice is slanted, the wind flows along the slope and passes smoothly through the front grill body.
この結果、風量のダウンおよび騒音の増大を防
げるようになる。 As a result, it becomes possible to prevent a reduction in air volume and an increase in noise.
実施例
以下、本発明の一実施例を第１図、第２図第３
図、第４図にもとづいて説明する。Embodiment Hereinafter, one embodiment of the present invention will be described in FIG. 1, FIG. 2, and 3.
This will be explained based on FIG.

ｃのリブを設けたものである。 In FIG. 3, reference numeral 1 denotes an outdoor unit body, to which a fan cover 2, outer box sides 3 and 4, and a top plate 5 are attached, and a front grill body 6 is attached. 6a,
Reference numeral 6b is a fan guard and fan orifice integrally molded with the front grill body 6, and the fan guard 6a is a plurality of ribs having a rectangular cross section that protrude laterally from the front surface of the front grill body 6 and are integrally molded. Further, the fan orifice 6b is provided with steps inclined in the circumferential direction, and the ribs of the fan guard 6a are arranged along the steps.
It is provided with ribs c.

それが流通抵抗をより少なくしている。 In the above configuration, by driving the fan motor 8, the fan 7 rotates and the wind flows as shown by the arrow. That is, a portion of the air that hits the fan guard 6a smoothly passes through the front grill body 6, and a portion flows along the fan orifice 6b and the rib 6c and smoothly passes through the front grill body 6. In particular, by providing the ribs 6c, a rectifying effect occurs, which further reduces the flow resistance.
したがつて、風量ダウンおよび騒音の増大をす
ることなく、空気調和ができるものである。 Therefore, air conditioning can be achieved without reducing the air volume or increasing noise.
次に本発明の他の実施例について説明する。 Next, other embodiments of the present invention will be described.

利点を有するものである。Effects of the Invention As described above, the present invention provides a fan guard by integrally molding a plurality of ribs with a rectangular cross section that protrude laterally in the front side on the front grille body, and provides a fan guard that forms the ventilation circuit of an air conditioner. The orifice is also integrally molded at the same time, and the shape of the fan orifice is inclined in the circumferential direction of the fan orifice to provide steps, thereby preventing a decrease in air volume and an increase in noise. Furthermore, since the air volume does not decrease, the fan motor can also be made smaller and lighter. Further, by providing the ribs of the fan guard along the steps, there are various advantages such as increasing the strength of the fan guard.
