【発明の詳細な説明】 産業上の利用分野 本発明は、器体内部に部品の冷却及び送風を目である。[Detailed description of the invention] Industrial applications The present invention is designed to cool parts and blow air inside the container.

般的である。Conventional Structure and Problems Conventionally, when a fan motor 1 is attached to a device body 2 as shown in FIG. A common method is to fix the metal mounting plate 6 to a metal mounting plate 6, and then fix this metal mounting plate 6 to the container body 2 via a motor vibration isolating rubber 7 or the like using a container fastening screw 8.
この場合、設計的に配慮しなければならないものとして

性の変化を可能な限り少なくする串及び、ファンモータ
ー１の回転時に、主にファン９のアンバランスによって
発生する振動を、器体２に伝達しない様な構造でなけれ
ばならない。In this case, design considerations must first be made in terms of performance: a skewer that minimizes changes in the characteristics of the fan motor 1 due to leakage magnetic flux; The structure must be such that vibrations caused by unbalance are not transmitted to the vessel body 2.
理由として前者はファンモーター１の回ＩＶ数の低下、
後者は、ファンモーター１の振動による異常音の発生を
防ぐ為である。又、この時、上記欠陥を解消する為の部
品点数の増加、或いは使用桐ト１−の選定９組立て工数
の増加に伴なうコストアンプに対する設計的配慮も必要
である。The reason for the former is a decrease in the number of rotations of fan motor 1,
The latter is to prevent abnormal noise from occurring due to vibration of the fan motor 1. In addition, at this time, it is necessary to take into consideration the cost of the amplifier due to an increase in the number of parts to eliminate the above-mentioned defects, or an increase in the number of assembly steps required for selection of paulownia wood.

ではない。よって、ファンモーター１は振動しても器体
２に振動が伝わって異常音が発生しない防振構造とする
様、ゴム等の弾性体を介して締結する事が必要である。However, as one of the most effective means to reduce the leakage magnetic flux passing through the metal mounting plate 6 from the fan motor 1, it is recommended to replace the metal mounting plate 6 with a non-magnetic material such as austenitic stainless steel, aluminum, copper or copper. There are alloys, etc., but they are all expensive materials and have a big disadvantage in terms of cost. In addition, the vibration of the fan motor 1 caused by the unbalance of the fan 9 can be improved by balancing the fan 9.
Actually, when considering mass productivity and cost, this is not preferable. Therefore, it is necessary to fasten the fan motor 1 through an elastic body such as rubber so that the fan motor 1 has a vibration-proof structure that does not transmit the vibration to the device body 2 and generate abnormal noise even if it vibrates.
この時、ファンモーター１の回転数を低く押える事によ

非常に困臀なものである。At this time, it is possible to reduce the vibration by keeping the rotation speed of the fan motor 1 low, but this is actually very difficult in terms of design since the original purpose of cooling and air blowing ability is reduced. It is something.

を目的とする。OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and is very simple, and does not reduce the performance of the fan motor 1 due to leakage magnetic flux or transmit vibrations caused by unbalance of the fan 9 to the device body 2. The purpose is to realize this configuration at low cost.

減する事の可能な構成である。Structure of the Invention In order to achieve the above-mentioned object, the structure of the fan motor mounting device of the present invention is such that the fan motor mounting plate is made of resin, and a vibration-proof structure can be easily formed due to the excellent elasticity that is a characteristic of resin. This is a configuration that can greatly reduce the number of parts and costs by requiring only one assembly and two parts.

。Hereinafter, as for the operation of the above-mentioned configuration, as shown in FIG. 4, which is a view seen from the direction indicated by the mark in FIG. It is fixed to the boss 11 (b) of the bracket 10 made of aluminum. At this time, since the bosses 11 are arranged with a gap t, when the motor fastening screw 6 is tightened, the resin bracket 10 deforms within the elastic limit by the gap, and the iron core 3 closely adhere to. In other words, motor fastening screw 5
If it is tightened 1, the resin bracket 1o will be permanently attached.
The bracket fixes the iron core part 3 through its own elasticity, and the elasticity of the bracket itself absorbs the vibrations of the fan motor 1 when the fan 9 rotates, thereby transmitting the vibrations to the body 2 side. Not only does it not cause unpleasant abnormal noises, but also because the resin does not transmit magnetic flux,
Since leakage magnetic flux to the fan motor 1 can be almost ignored, there is no deterioration in the characteristics of the fan motor 1, and the resin material itself can be supplied at a very low cost compared to the intended non-magnetic material. Moreover, since the number of parts is small, the effect is tremendous.

When tightening the motor fastening screws 6, the fan motor 1 and the resin bracket 1 are attached to the fan motor 1 and the resin bracket 1.

In addition to preventing deterioration of characteristics due to the vibration-proof structure and leakage magnetic flux, it is possible to reduce the number of mounting screws and man-hours. This configuration is similar to Section 6.7.
As shown in the figure, a step 12 or a recess 13 having a shape that locks or engages with the motor core 3 etc. is provided in the resin bracket 10, and as shown in FIG. A feature is that a motor fastening screw 5 is arranged at position 14. When the fan motor 1 is attached to the container body 2 through the resin bracket 10 in this way, the outer dimensions of the resin bracket 10 and the dimensions of the iron core 3 of the fan motor 1 are approximately equal, as shown in FIG. By providing an opening 16 at approximately the center of the face-shaped resin bracket 10, the area of the intake opening 16 provided in the container body 2 is reduced when the container body 2 is placed as shown in FIG. By increasing , it is possible to reduce the intake resistance during cooling and air blowing, which is the original purpose of the fan motor 1, and to make maximum use of the performance of the fan motor 1.
