本発明は一般家庭で使われるミキサー等の電動機器に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to electric appliances such as mixers used in general households.

従来、この種の電動機器は、第１図で示す様に、駆動用

固着されており、この冷却ファン５の効率を高めるため
に、エアガイトロが七−夕１に取イ・」けられている。Conventional Structure and Problems Conventionally, in this type of electric equipment, as shown in FIG. 1, a driving motor 1 is elastically supported on a main body 3 by a vibration isolating rubber 2. A cooling fan 5 is fixed to the opposite drive side of the motor 1, and in order to increase the efficiency of the cooling fan 5, an air guide is installed on the Tanabata 1.
又、排気孔７を有する本体底面８とエアガイド６の間に
は隙間９か設けられてあり、モーり１の振動がエアガイ

この隙間９のため、矢印１０て示す冷却風の一部が排気

ファン５の径は８扱以上に大きく設＝−ｉ サしており
、冷却ファン騒音を増大させる結果とな−）ている。Further, a gap 9 is provided between the bottom surface 8 of the main body having the exhaust hole 7 and the air guide 6 to prevent vibrations of the morrow 1 from being transmitted through the air guide 6 to the main body 3. However, due to this gap 9, a portion of the cooling air indicated by the arrow 10 is not exhausted and flows, reducing the cooling efficiency of the cooling fan 5. For this reason, in order to secure the necessary cooling air, the diameter of the cooling fan 5 is set to be larger than 8 mm, which results in an increase in cooling fan noise.
そこで第２図で示す様に、エアカイト６を本体底面８に
固着し、モータ１とエアガイトロの接触をたてはモータ
１の振動がエアガイトロを通して本体３に伝わる事もな

風成分が大きくなり、冷却ファン５による冷却効率が悪

せる事になる。Therefore, as shown in FIG. 2, by fixing the air kite 6 to the bottom surface 8 of the main body and making contact between the motor 1 and the air kite, the vibrations of the motor 1 will not be transmitted to the main body 3 through the air kite, and as shown in FIG. There is no gap 9, and there is no circulating cooling air component, improving the efficiency of the cooling fan 5.
The gap 12 between these parts needs to be designed to be larger than the example shown in FIG. 1. Therefore, the cooling air component circulating through this gap 12 becomes large, and the cooling efficiency of the cooling fan 5 deteriorates, resulting in an increase in the cooling fan noise as described above.
以上述べた様に従来の構造ではモータの防振と冷却ファ

て充分彦低騒音化が実現出来なかった。As mentioned above, with the conventional structure, it is difficult to simultaneously improve both motor vibration isolation and cooling fan efficiency, and as a result, sufficient noise reduction cannot be achieved.

できる。Composition of the Invention An electric device of the present invention includes a driving motor, a cooling fan fixed to a shaft on the non-driving side of the motor, and a main body including a motor and a cooling fan therein, and a main body bottom facing the cooling fan. The rubber ring-shaped disc includes a main body having an exhaust hole, and a rubber ring-shaped disc located on the outer periphery of the cooling fan and fixed to the motor so that the cooling fan is located on the inner periphery thereof. The outer periphery of the exhaust hole is brought into elastic contact with the main body at the outer periphery of the exhaust hole to form an exhaust passage, which prevents vibrations from the motor from being transmitted to the main body and improves the efficiency of the cooling fan. Fan noise can also be improved.
実施例の説明
以下、添付図面に基づいて本発明の一実施例について説
明する。第３図において１４は駆動用のモータであり、
防振ゴム１５を介して本体１６に弾性支持されている。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 3, 14 is a driving motor,
It is elastically supported by the main body 16 via vibration isolating rubber 15.

いる。A cooling fan 18 is fixed to the non-drive side shaft 17 of the motor 14 . An exhaust hole 2Q is provided on the bottom surface 19 of the main body facing the cooling fan 18. A rubber ring-shaped disk 21 is provided on the outer circumference of the cooling fan 18, and is fixed to the motor 14 so that the cooling fan 18 is located on the inner circumference thereof. The outer periphery 21' of the rubber ring-shaped disk 21 is lip-shaped, and its entire periphery is in elastic contact with the inner surface of the substantially cylindrical air guide 22. A substantially cylindrical air guide 22 surrounds the motor 14 and is molded integrally with the main body 16 so that its end surface becomes the exhaust hole 20.
Together with the rubber ring-shaped disc 21, it forms an exhaust passageway.
上記構成において、動作全説明する。モータ１４を駆動
すると、冷却フィン１８が回転し、冷却風が矢印２３の
方向に流れてモータ１４を冷却する。In the above configuration, the entire operation will be explained. When the motor 14 is driven, the cooling fins 18 rotate and cooling air flows in the direction of the arrow 23 to cool the motor 14.
この時、ゴム質リング状円板２１と冷却ファン１８との
隙間２４はゴム質リング状円板２１がモータ１４に固定
されているため、モータが振動しても一定に保たれ冷却

周はその弾性を利用してエアガイド２２の内面に当接し
ているため、モータ１４が振動してもこの間に隙間が広
がる事も無く、冷却風がこの間から環流する事も無い。At this time, since the rubber ring disc 21 is fixed to the motor 14, the gap 24 between the rubber ring disc 21 and the cooling fan 18 is kept constant even if the motor vibrates, and the cooling fan 18 There is no contact with the rubber ring-shaped disc 21, and the gap 24 can be set to the minimum within the range of component dimensional accuracy, and the ability of cooling air to circulate through this gap has been greatly improved compared to the past. can. The outer periphery of the rubber ring-shaped disk 21 uses its elasticity to abut against the inner surface of the air guide 22, so even if the motor 14 vibrates, the gap between them does not widen, and cooling air can circulate from this gap. There's nothing to do.

めて少な〈従来に比へ悪くなる事は無い。By focusing on the above two points, it is possible to greatly reduce the circulating component of the cooling air, and the efficiency of the cooling fan 18 can be greatly increased.
lJ (according to experiments, it is improved by about 20% compared to the conventional example shown in Figure 1), and as a result, it is possible to obtain the necessary cooling air with the cooling fan 5, which has a smaller diameter than the conventional one. Therefore, the noise of the cooling fan 6 can be significantly reduced. When compared with the conventional example shown in FIG. 1, a reduction of 2 to 3 dB (A) was obtained. The vibration of the motor 14 is insulated by the vibration isolating rubber 15, and at the same time, the elasticity of the rubber ring-shaped disc 21 fixed to the motor 14 also insulates the vibration of the air guide 2, and the motor vibration transmitted to the main body 16 is is extremely low (nothing worse than before).

In FIG. 4, the outer peripheral portion 25' of the rubber ring-shaped disk 26 is directed downward and directly onto the bottom surface 26 of the main body. It is an example in which the outer circumferential portion 27' of the rubber ring-shaped disk 27 is elastically abutted against the ring-shaped rib 29 provided on the bottom surface 28 of the main body. This is an example where
Both of them form an exhaust passage A, similar to the embodiment described above. It goes without saying that the material of the rubber ring-shaped disk described in Ait is limited to rubber.
