(57) [Summary] [Purpose] The present invention relates to a smoke prevention structure for a woodworking dust collector that may suck wood chips into the casing. The purpose of this invention is to improve safety by preventing smoke from being emitted even if wood chips are inhaled. [Configuration] A fan 6 is housed in the casing 5.
is fixed to the shaft 12. A fan cover 7 is screwed to the casing 5 and covers the fan 6. A metal protrusion 7b is welded and fixed to the fan side of the fan cover 7 and the inner periphery of the suction port.
Description
【０００１】0001
本考案はケーシング内に木片を吸い込む可能性がある木工用集じん機の発煙防 止構造に関するものである。 This invention is a smoke prevention device for woodworking dust collectors that may suck wood chips into the casing. This relates to the stop structure.

従来技術を第５図に沿って説明する。モータによって回転するファン６を収納 するケーシング５と、ファン６を覆い吸込口７ａを有するファンカバー７によっ て構成された木工用集塵機。 The prior art will be explained with reference to FIG. Contains a fan 6 rotated by a motor A casing 5 that covers the fan 6 and a fan cover 7 that has a suction port 7a. Dust collector for woodworking.
【０００３】0003
図５によって従来品の問題点を説明する。 The problems of the conventional product will be explained with reference to FIG.
【０００４】 ケーシング５内にファン６が収納されファン６は吸込口７ａを有するファンカ バー７に覆われている。羽根６ａのＡ部とファンカバー７の側面で楔状の隙間が 形成されるため、吸込口７ａから木片が吸い込まれると木片は羽根６ａの斜面に そって移動しＡ部の隙間にはさまる。はさまった木片はファン６と一緒に回転す るためファンカバー７との間で摩擦熱が発生し発煙が起きるという問題があった 。0004 A fan 6 is housed in the casing 5, and the fan 6 is a fan case having a suction port 7a. Covered by bar 7. There is a wedge-shaped gap between part A of the blade 6a and the side of the fan cover 7. Therefore, when a piece of wood is sucked in from the suction port 7a, the piece of wood is placed on the slope of the blade 6a. It moves along and gets stuck in the gap in section A. The stuck piece of wood will rotate together with fan 6. Therefore, there was a problem in that frictional heat was generated between the fan cover 7 and smoke. .
【０００５】 本考案の目的は発煙を防止し、安全性を高めることである。[0005] The purpose of this invention is to prevent smoke generation and improve safety.
【０００６】[0006]
上記目的は、ファンの羽根内径側先端とファンカバーのファンの側面との間に 突起を設け、羽根の斜面にそって移動してきた木片をはじき飛ばすことにより達 成される。 The above purpose is to connect the tip of the fan blade on the inner diameter side and the side of the fan on the fan cover. This is achieved by installing protrusions to repel pieces of wood that move along the slope of the blade. will be accomplished.
【０００７】[0007]
【作用】 上記のように構成された木工用集じん機では、吸込口から入った木片はファンの 羽根の斜面に沿って先端へ移動するが、ファンカバーのファン側と吸込口内周に 沿って突起部が設けられているため、ファンカバー内側にはさまることがなくフ ァンの回転によりはじき飛ばされる。[Effect] In the woodworking dust collector configured as above, the wood chips that enter through the suction port are removed by the fan. It moves to the tip along the slope of the blade, but on the fan side of the fan cover and the inner circumference of the suction port. Since there is a protrusion along the fan cover, the fan cover will not get caught inside the fan cover. It is thrown away by the rotation of the fan.

本考案の実施例を図１〜図４により説明する。 An embodiment of the present invention will be described with reference to FIGS. 1 to 4.
【０００９】 ケーシング５にファン６が収納されファン６は電動機のシャフト１２にワッシ ャ８、スプリングワッシャ９、ボルト１０で固定直結されている。ケーシング５ にファンカバー７、ノズル２がボルト固定されファン６を覆っている。ファンカ バー７の内周には金属製突起部７ａが溶接固定されている。ケーシング５はカバ ー１で覆われ、カバー１に設けた吐出口にダストバッグ４が着脱自由に取付けら れている。[0009] A fan 6 is housed in the casing 5, and the fan 6 is attached to the shaft 12 of the electric motor with a washer. They are fixedly and directly connected by a spring washer 8, a spring washer 9, and a bolt 10. Casing 5 A fan cover 7 and a nozzle 2 are bolted to cover the fan 6. Funka A metal protrusion 7a is welded and fixed to the inner circumference of the bar 7. Casing 5 is a hippo -1, and a dust bag 4 is detachably attached to the outlet provided in the cover 1. It is.
【００１０】 次に動作を説明する。0010 Next, the operation will be explained.
【００１１】 吸込口７ａから吸引された木片１１は遠心力によりファン６の羽根６ａの斜面 に沿って先端Ａ部に移動する。しかし、ファンカバー７のファン側と吸込口内周 に沿って突起部７ｂが設けられているため、木片１１は羽根６ａとファンカバー ７の隙間にはさまることがなくはじき飛ばされる。[0011] The wood chips 11 sucked in from the suction port 7a are pushed onto the slope of the blades 6a of the fan 6 by centrifugal force. Move along to the tip A section. However, the fan side of the fan cover 7 and the inner circumference of the suction port Since the protrusion 7b is provided along the blade 6a, the wooden piece 11 It does not get caught in the gap between 7 and is repelled.
【００１２】0012
本考案によれば、ファンカバーのファン側と吸込口内周に沿って突起部を設け たので、木片を吸い込んだ場合に発煙を防止できる。 According to the present invention, protrusions are provided along the fan side of the fan cover and the inner circumference of the suction port. This prevents smoke from being produced if wood chips are inhaled.
