Description

本願発明は、空気調和機用室外機ユニットの前面板の構造に関するものである。   The present invention relates to a structure of a front plate of an outdoor unit for an air conditioner.

一般に空気調和機用の室外機は、トランク型等の本体ケーシング内の機械室部分に圧縮機等の機械装置、ファン室部分に熱交換器、送風機(ファン)等を各々配設して構成されている。   In general, an outdoor unit for an air conditioner is configured by disposing a mechanical device such as a compressor in a machine room portion in a trunk-type main body casing, a heat exchanger, a fan (fan), and the like in a fan chamber portion. ing.

そして、上記本体ケーシングのファン室側背面(および側面)には空気吸込口が、また前面には空気吹出口が設けられている。そして、空気吹出口には、さらにベルマウスが設けられている。   The main body casing is provided with an air suction port on the fan chamber side rear surface (and side surface) and an air outlet on the front surface. A bell mouth is further provided at the air outlet.

このベルマウスは、上記本体ケーシングのフロントキャビネットの一部分により構成されている。   This bell mouth is constituted by a part of the front cabinet of the main body casing.

そして、上記送風機は、上記機械室内の上記空気吹出口と上記空気吸込口側熱交換器との間の空気通路にファンモータ取付台を設け、該ファンモータ取付台に対して送風機の羽根車が流側になるようにしてファンモータを取り付けるようになっている(特許文献1参照)。 The blower is provided with a fan motor mounting base in an air passage between the air outlet and the air inlet side heat exchanger in the machine room, and an impeller of the blower is connected to the fan motor mounting base. so that the attachment of the fan motor so as to become lower stream side (see Patent Document 1).

しかしながら、このような従来の室外機ユニットの構成では、送風機のファンモータを取り付けているファンモータ取付台と、ベルマウスを形成しているフロントキャビネットをそれぞれ別体に構成しているので、部品点数が多い。このため、製造時の組立工数も多く、組立時の作業効率が悪いという問題がある。   However, in the configuration of such a conventional outdoor unit, since the fan motor mounting base to which the fan motor of the blower is mounted and the front cabinet forming the bell mouth are configured separately, the number of parts There are many. For this reason, there are many assembly man-hours at the time of manufacture, and there exists a problem that the working efficiency at the time of assembly is bad.

また、ベルマウスと、ファンモータないしファン羽根車との芯ずれが生じ易い問題もある。   In addition, there is a problem that misalignment is likely to occur between the bell mouth and the fan motor or fan impeller.

さらに、ベルマウスはフロントキャビネットにファン羽根車の外径よりも大きい内径の丸孔を開けることにより形成されるので、その丸孔抜き跡の金属板の捨て材が多く、材料ロスが大きい。   Furthermore, since the bell mouth is formed by opening a round hole with an inner diameter larger than the outer diameter of the fan impeller in the front cabinet, there are many discarded materials of the metal plate of the round hole removal trace, and the material loss is large.

そこで、従来、上記のような送風機を具備した室外機ユニットにおいて、上記熱交換器を通した送風機からの風を外部に導くベルマウスと、上記送風機の駆動用モータを支持するモータベースとをフロントキャビネット部分に一体成形したものが提案されている(特許文献2参照)。   Therefore, conventionally, in an outdoor unit equipped with a blower as described above, a bell mouth that guides the wind from the blower that has passed through the heat exchanger to the outside, and a motor base that supports a motor for driving the blower are provided on the front side. What was integrally molded by the cabinet part is proposed (refer patent document 2).

このような本体ケーシングのフロントパネルをファンモータの支持板とし、それにベルマウスを一体に形成する構成によれば、送風機のベルマウスと送風機の駆動用モータを支持するモータベースとがフロントパネルに一体成形されていることから、ベルマウスとモータベースとを各々別部材により形成する先の従来例に比較して、部品点数の削減を図ることができる。   According to such a structure in which the front panel of the main body casing is used as a support plate for the fan motor and the bell mouth is integrally formed therewith, the bell mouth of the blower and the motor base that supports the drive motor of the blower are integrated with the front panel. Since it is molded, the number of parts can be reduced as compared with the prior art in which the bell mouth and the motor base are formed by separate members.

このため、組立工数を削減することができるので、その分組立時の作業効率を向上させることができ、コスト低減を図ることができる。   For this reason, since the number of assembling steps can be reduced, the work efficiency at the time of assembling can be improved correspondingly, and the cost can be reduced.

また、ベルマウスとモータベースとを一体成形する際に、芯合せ等の位置決めを容易かつ高精度に行なうことができるので、これらベルマウスとモータベース、並びにこのモータベースに取り付けられる駆動用モータないしファン羽根車の翼等との芯合せ等の位置決め精度を容易に向上させることができる。   Further, when the bell mouth and the motor base are integrally molded, positioning such as centering can be performed easily and with high accuracy. Therefore, the bell mouth and the motor base, and a driving motor attached to the motor base or Positioning accuracy such as alignment with the fan impeller blades can be easily improved.

このために、さらにファン羽根車の翼等とベルマウスとのクリアランス精度を向上させることができ、送風量を増大させることもできる。   For this reason, the clearance accuracy between the fan impeller blades and the bell mouth and the bell mouth can be further improved, and the air flow rate can be increased.

In order to improve it, more complicated processing is required. Moreover, when the plate | board thickness of a front panel is thin, it receives restrictions on the height of a bell mouth, and it is difficult to obtain a higher static pressure and a large air volume.

また、ベルマウスの空気吸込側および空気吹出側縁部の空気流ガイド面をフレア構造に形成することが難しく、本来の有効な整流機能を実現することができない。   Further, it is difficult to form the air flow guide surfaces of the air inlet side and the air outlet side edge of the bell mouth in a flare structure, and the original effective rectifying function cannot be realized.

本願発明は、このような問題を解決するためになされたもので、本体ケーシングの空気吹出面側パネルの開口部分に、該開口の中央にモータの支持部を形成する複数本の放射状の補強ステイを設けるとともに、ベルマウスの空気流下流側外周縁部の一部を上記パネルの上記開口部分の内側から補強ステイの間を通して表側に突出させ、該突出部を折り曲げて同パネル面上に接合固定する構造とすることによって、十分なファンモータ支持強度と自由なベルマウス形状を実現することができるようにした空気調和機用室外機ユニットを提供することを目的とするものである。   The present invention has been made to solve such problems, and a plurality of radial reinforcing stays are formed in the opening portion of the air blowing surface side panel of the main body casing, and a motor support portion is formed at the center of the opening. A part of the outer peripheral edge of the bell mouth on the downstream side of the air flow is projected from the inside of the opening of the panel to the front side through the reinforcing stay, and the projecting part is bent and fixed on the panel surface. It is an object of the present invention to provide an outdoor unit for an air conditioner capable of realizing sufficient fan motor support strength and a free bell mouth shape.

The bell mouth 11 can be formed simply and at low cost.

さらに、以上の構成の場合、上記各補強ステイ2b,2b・・・のステイ部は、それぞれその板面が空気の流通方向と平行になるように捩り、さらに必要に応じて弓なりに反り返るように加工されていることを特徴としている。   Further, in the case of the above configuration, the stay portions of the reinforcing stays 2b, 2b,... Are twisted so that the plate surfaces thereof are parallel to the air flow direction, and further bowed as necessary. It is characterized by being processed.

この反り返り方向は、本体ケーシング1の内側方向又は外側方向の何れでもよく、また内側方向と外側方向に交互に方向を変えて弓なりに反り返らせるようにしてもよい。   This warping direction may be either the inner side or the outer side of the main casing 1, or the direction may be alternately changed to the inner side and the outer side so as to be bowed.

このような構成によれば、開口2a部分に放射状に複数本の補強ステイ2b,2b・・・があっても、それ自体が空気流の通風抵抗となることを可及的に回避することができる。また、弓なりに反り返っていることにより、補強ステイ2b,2b・・・自体の強度、剛性が一層向上する。   According to such a configuration, even if there are a plurality of reinforcing stays 2b, 2b,... Radially in the opening 2a portion, it is possible to avoid as much as possible that the air flow itself becomes a ventilation resistance. it can. Further, since the bow is bent, the strength and rigidity of the reinforcing stays 2b, 2b,.

以上の結果、この発明の実施形態によれば、十分なファンモータ支持強度と自由なベルマウス形状を実現することができる低コストな空気調和機用室外機ユニットを提供することが可能となる。   As a result, according to the embodiment of the present invention, it is possible to provide a low-cost outdoor unit for an air conditioner that can realize sufficient fan motor support strength and a free bell mouth shape.
