〈産業上の利用分野〉
本考案は電動機により刈刃を回転させるように
した電動芝刈機に関するものである。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an electric lawn mower whose cutting blades are rotated by an electric motor.
〈従来の技術〉
電動芝刈機は、その電動機を冷却しなければな
らないと同時に、刈り取つた芝を周囲に撒き散ら
すことなく集草容器等に送り出せるようにするこ
とが望ましい。<Prior Art> In an electric lawn mower, it is desirable that the electric motor must be cooled and at the same time be able to send the cut grass to a grass collecting container or the like without scattering the cut grass around the lawn mower.
しかし乍ら、電動機を冷すには比較的大量の風
を必要とし、逆に刈り取つた芝を効率良く集草容
器内に送り込むには比較的少量の風の方が良いた
め、電動機を冷すのに必要な大量の風をそのまま
集草用の風に使用することが難しかつた。即ち、
電動機を冷すのに必要な大量の風をそのまま集草
用の風に使用すると、集草容器内に入る風が強過
ぎて集草容器内で反転して取り入れ口から出て行
くため、刈り取つた芝を集草容器内に効率良く送
り込むことが出来なくなつてしまい、集草用の風
を少なくすると電動機を十分に冷すことが出来な
くなつてしまう不具合を生じるのである。又、電
動機を覆う機枠の上部に冷却用の通風口を開口す
れば、冷却用の風量は少しで済むが、すると芝刈
機本体の機枠とは別体に成形しなければならず、
コスト高になると共に、その冷却用通風口から雨
水が浸入しないようにシール構造を設けなければ
ならなくなる不具合を生じる。 However, cooling the electric motor requires a relatively large amount of wind, and conversely, it is better to use a relatively small amount of wind to efficiently feed the cut grass into the grass collection container. It was difficult to use the large amount of wind needed to collect grass directly. That is,
If the large amount of air needed to cool the electric motor is directly used for grass collection, the wind entering the grass collection container will be too strong and will reverse inside the container and exit from the intake port, making it difficult to cut the grass. The removed grass cannot be efficiently fed into the grass collection container, and if the grass collection air is reduced, the electric motor cannot be cooled sufficiently, resulting in a problem. Also, if a cooling ventilation hole is opened at the top of the machine frame that covers the electric motor, the amount of cooling air can be reduced to a small amount, but then the machine frame must be formed separately from the lawnmower body.
In addition to increasing costs, this also creates a problem in that a sealing structure must be provided to prevent rainwater from entering through the cooling vent.
〈考案が解決しようとする問題点〉
本考案はこの様な従来の不具合に鑑みてなされ
たものであり、電動機を冷すのに必要な風量を少
なくすることなく、しかもその風を集草用の風に
使用して刈り取つた芝を効率良く集草容器内に送
り込むことが出来、尚且つその構成が簡単な電動
芝刈機を提供せんとするものである。<Problems to be solved by the invention> The present invention was devised in view of these conventional problems. To provide an electric lawn mower which can efficiently feed cut grass into a grass collecting container using wind and has a simple structure.
〈問題点を解決するための手段〉
係る目的を達成する本考案電動芝刈機は、機枠
内に電動機及びフアンを備えたフアンケースを設
置し、該フアンケースの吹出口を機枠下面に設置

The vehicle is installed, wheels 7 are attached to the front, rear, left and right sides, and an operating handle 8 is attached to the rear. An air intake port 9 is formed at the top of the machine frame 1 to take air into the interior.
A guide path 11 is integrally formed at the rear lower part to guide the grass cut by the cutting blade 5 directly into the grass collection container 10.

るための通口である。 The electric motor 2 is installed inside the machine frame 1 so that air flows through the air intake port 9 of the machine frame 1 and the inside of the fan case 4, and is a drive mechanism that rotates the fan 3 and the cutting blade 5 inside the fan case 4. Connect to 6.
In addition, 12 in the figure is a vent for circulating air inside the electric motor 2.

１の下面に設置した刈刃５の前方に臨ませる。 The fan case 4 is installed within the machine frame 1, and accommodates the fan 3 rotated by the drive mechanism 6 of the electric motor 2 inside the fan case 4. The fan case 4 has an opening 13 formed in the upper part to take in air. The air outlet 14 is made to face in front of the cutting blade 5 installed on the lower surface of the machine frame 1.
フアンケース４の吹出口１４には、刈刃５から
機枠１のガイド路１１に至る風量を調節する邪魔
板１５を上下移動自在に取付ける。 A baffle plate 15 for adjusting the amount of air from the cutting blade 5 to the guide path 11 of the machine frame 1 is attached to the air outlet 14 of the fan case 4 so as to be vertically movable.

It is clamped and engaged with the mouth edge 14a of the air outlet 14 of No. 4, and is mounted so as to be vertically movable.
尚、刈刃５は周知のロータリー回転刃でも良い
し、図示例の如く回転刃と固定刃を同軸状に重ね
合わせて芝を刈り取るようにしたものでも良い。 The cutting blade 5 may be a well-known rotary blade, or it may be a rotary blade and a fixed blade coaxially superimposed on each other to cut the grass, as shown in the illustrated example.

まれる。 However, when the electric motor 2 is operated, the mowing blade 5 is rotated by the drive mechanism 6 and at the same time, the grass is cut.
The fan 3 rotates to circulate the air inside the machine frame 1 and take air into the machine frame 1 from the air intake port 9 of the machine frame 1 to cool the electric motor 2. It starts blowing wind to collect grass. At this time, the amount of air blown toward the cutting blade 5 is adjusted by moving the baffle plate 15 attached to the air outlet 14 of the fan case 4 upward or downward. That is, when mowing wet grass or long grass, moving the baffle plate 15 slightly upward increases the amount of air blown toward the cutting blade 5, and when mowing dry, light grass, the baffle plate 15 moves slightly upward. By moving the plate 15 slightly downward, the amount of air blown toward the cutting blade 5 is reduced.
Note that the wind blown out from above the baffle plate 15 of the air outlet 14 collides with the inner wall 1a of the machine frame 1, etc., and is scattered. The grass cut by the grass-collecting wind blown out from the air outlet 14 of the fan case 4 is removed from the machine frame 1.
The grass is fed into the grass collecting container 10 through the guide path 11 of the grass collecting container 10 .
