Description
本実用新案は扇風機の羽根群に関する。 This utility model relates to a fan blade group.
従来の扇風機の羽根群は羽根が単層であり、その中には、一つの回転スリーブと、一組の羽根群とがあり、前記羽根群には複数の羽根が環状に配列して回転スリーブの外周面に固定される。単層羽根の扇風機には、後部中心の風域から空気が吸入できず、空気の吸入効果が悪く、また送風効果も良くないという問題点がある。 The blade group of the conventional fan has a single layer of blades, and there is one rotating sleeve and one set of blade group, and the blade group has a plurality of blades arranged in an annular shape. It is fixed to the outer peripheral surface. The single-layer blade fan has a problem that air cannot be sucked from the air region at the center of the rear, the air sucking effect is bad, and the air blowing effect is not good.
以上の問題を解決するために、ある業者は解決方法を提供した。ＣＮ２００９９９７５９Ｙは一種の改良した多層羽根を有する扇風機を提供する、その公告日は２００８年１月２日である。前記多層羽根は二層の羽根で、その中には、一つの回転スリーブと、一組の先羽根群と、一組の後羽根群とがあり、前記先羽根群には複数の先羽根が環状に配列して回転スリーブの外周面に固定され、前記後羽根群には複数の後羽根が環状に配列して回転スリーブの外周面に固定され、前記先羽根群は後羽根群の前に位置する。前記扇風機には以下の問題があり、１）扇風機の先部中心の無風域を補償できるが、先置きの小羽根の風量は後ろ置きの大羽根から隠され、送風効果に影響を及ぼし、２）小羽根と大羽根は別々にデザインしてから組み立てられ、このようなデザインを組み立てる時、環境影響を受けて、小羽根と大羽根の相対位置がずれ、または小羽根と大羽根とが重なる恐れがあり、さらに、組立が複雑で、組立コストが高い、３）扇風機後部の風域から空気を吸い込むことができず、空気の吸入効果が悪く、送風効果も良くない。 In order to solve the above problems, a contractor provided a solution. CN2009999759Y provides a fan with a kind of improved multi-layer blade, the announcement date is January 2, 2008. The multi-layer blade is a two-layer blade, and includes a rotating sleeve, a set of leading blade groups, and a set of trailing blade groups, and the leading blade group includes a plurality of leading blades. A plurality of rear blades are annularly arranged and fixed to the outer peripheral surface of the rotating sleeve, and the leading blade group is arranged in front of the rear blade group. To position. The electric fan has the following problems: 1) Although it can compensate for the no wind area at the center of the front part of the electric fan, the air volume of the front small blade is hidden from the large blade at the rear and affects the air blowing effect. ) Small blades and large blades are designed separately and then assembled. When assembling such a design, the relative position of the small blades and large blades shifts or the small blades and large blades overlap due to environmental effects. Further, the assembly is complicated and the assembly cost is high. 3) Air cannot be sucked in from the air region at the rear of the fan, the air suction effect is poor, and the air blowing effect is not good.
本実用新案の目的として、一種の扇風機の羽根群を提供し、送風効果が悪く、組立が複雑であるという従来扇風機の問題を解決する。 As an object of this utility model, a kind of fan blade group is provided to solve the problem of the conventional fan that the ventilation effect is poor and the assembly is complicated.
本実用新案は以下の技術手段を採用した。 This utility model adopted the following technical means.
扇風機の羽根群が回転し、そして、後ろ側から風を吸い込んで、先側へ風を送って、その中には、一つの回転スリーブと、１組の先羽根群と、それに１組の後羽根群とがあり、前記先羽根群には複数個の先羽根が環状に配列して回転スリーブの外周面に固定され、前記後羽根群には複数個の後羽根が環状に配列して回転スリーブの外周面に固定され、前記先羽根群は後羽根群の前に位置し、さらに、前記先羽根は後羽根より大きい。 The fan blades rotate, suck the wind from the back side and send the wind to the front side, including one rotating sleeve, one pair of front blades, and one after There are blade groups, and a plurality of front blades are arranged in an annular shape in the front blade group and fixed to the outer peripheral surface of the rotary sleeve, and a plurality of rear blades are arranged in an annular shape in the rear blade group and rotate. It is fixed to the outer peripheral surface of the sleeve, the leading blade group is located in front of the trailing blade group, and the leading blade is larger than the trailing blade.
もっとも好ましい実施例によれば、前記回転スリーブと、先羽根と、後羽根とは一体成型される。 According to the most preferred embodiment, the rotating sleeve, the leading blade, and the trailing blade are integrally formed.
もっとも好ましい実施例によれば、前記先羽根の数は後羽根の数と同じで、さらに、前記複数個の先羽根は複数個の後羽根と交錯する。 According to a most preferred embodiment, the number of leading blades is the same as the number of trailing blades, and the plurality of leading blades intersect with a plurality of trailing blades.
もっとも好ましい実施例によれば、前記先羽根の数は少なくとも三つである。 According to the most preferred embodiment, the number of leading blades is at least three.
もっとも好ましい実施例によれば、前記先羽根の長さは後羽根の長さより長い。 According to the most preferred embodiment, the length of the leading blade is longer than the length of the trailing blade.
もっとも好ましい実施例によれば、前記回転スリーブの半径と、先羽根の長さと、後羽根の長さとの割合は１：２．５−３．５：１−１．５である。 According to the most preferred embodiment, the ratio of the radius of the rotating sleeve, the length of the leading blade and the length of the trailing blade is 1: 2.5-3.5: 1-1.5.
本技術手段と従来技術とを比べると、本発明には二層の羽根が設置され、そして、大羽根は先に位置し、小羽根は後ろに位置するので、回転する時、小羽根は扇風機の後部中心の風域から空気を吸い込んで、扇風機後部の吸気量を増加し、扇風機全体の風力も増加できる。そして、回転スリーブと、先羽根と、後羽根とは一体成形されるので、組み立てる時、小羽根が大羽根と重なったり、またずれたりする恐れがなく、成形や組立が簡単で、組立コストも節約できる。複数個の先羽根は複数個の後羽根と交錯するので、先羽根が吸気するのを後羽根に隠されることを避けることができる。 Comparing this technical means with the prior art, the present invention has two layers of blades, and the large blades are located at the front and the small blades are located at the back. By sucking air from the wind area at the center of the rear of the fan, the intake air at the rear of the fan can be increased, and the wind power of the entire fan can be increased. And since the rotating sleeve, the leading blade and the trailing blade are integrally molded, there is no fear that the small blade overlaps or shifts from the large blade when assembling, the molding and assembly are simple, and the assembly cost is also low. Can save. Since the plurality of leading blades intersect with the plurality of trailing blades, it is possible to avoid the leading blades from being hidden by the trailing blades.
以下に図と好ましい実施形態とをまとめて、本実用新案の内容を一層詳しく説明する。 The contents of the utility model will be described in more detail below by combining the drawings and preferred embodiments.
