以下、本発明を適用した画像形成装置について説明を行う。
＜実施例１＞
図１は本発明の実施例１に係る画像形成装置の排気ダクトの位置を示す断面図（Ａ）、本発明の実施の形態に係る同断面図（Ｂ）、そして正面図（Ｃ）である。本実施例の画像形成装置の排気ダクト３は、画像形成装置本体１の背面２にあって、下方向に向けて取り付けられている。そして排気ダクト３の排気口５は、水平方向の断面で形成してある。排気口５内の排気の流れの上流側には、防塵フィルタ６、脱臭フィルタ８が設けられている。
Hereinafter, an image forming apparatus to which the present invention is applied will be described.
<Example 1>
FIG. 1 is a cross-sectional view (A) showing a position of an exhaust duct of an image forming apparatus according to Embodiment 1 of the present invention, a cross-sectional view (B) according to an embodiment of the present invention, and a front view (C). . The exhaust duct 3 of the image forming apparatus according to the present embodiment is attached to the back surface 2 of the image forming apparatus main body 1 and directed downward. And the exhaust port 5 of the exhaust duct 3 is formed in the cross section of a horizontal direction. A dustproof filter 6 and a deodorizing filter 8 are provided on the upstream side of the exhaust flow in the exhaust port 5.
また、脱臭フィルタ８に流れる気流が均一になるように、脱臭フィルタ８の上流側には排気ダクト３の内部にV字形状に配置された整流リブ１０が形成されている。 Further, a rectifying rib 10 arranged in a V shape inside the exhaust duct 3 is formed on the upstream side of the deodorizing filter 8 so that the airflow flowing through the deodorizing filter 8 is uniform.
次に本実施例の機能、動作について説明する。排気ファン４は軸流ファンで、軸流ファンから排気された気流は、軸流ファンの中心部では気流の流れが弱い特性があるが、排気ダクト３内部にV字形状に配置された整流リブ１０よって脱臭フィルタ８へ均一に分流され、脱臭フィルタ８の吸着面が均一に有効利用される。この時、画像形成装置本体１内で発生したトナーやオゾン等の臭気成分は脱臭フィルタ８に吸着され、排気口５に達するまでの臭気成分が減少する。さらに、排気ダクト３の排気口５を下方向の排気としているため、下向きの排気方向の効果とあいまって臭気が押さえられる。 Next, functions and operations of the present embodiment will be described. The exhaust fan 4 is an axial fan, and the airflow exhausted from the axial fan has a characteristic that the airflow is weak at the center of the axial fan, but the rectifying ribs arranged in a V shape inside the exhaust duct 3 Accordingly, the flow is evenly divided into the deodorizing filter 8, and the adsorption surface of the deodorizing filter 8 is uniformly and effectively used. At this time, odor components such as toner and ozone generated in the image forming apparatus main body 1 are adsorbed by the deodorizing filter 8 and the odor components until reaching the exhaust port 5 are reduced. Furthermore, since the exhaust port 5 of the exhaust duct 3 is configured as downward exhaust, the odor is suppressed in combination with the effect of the downward exhaust direction.
なお本実施例では、着脱可能な脱臭フィルタ８がシール材９を介して取り付けられている。そのため、臭気除去フィルタ８が寿命に達した時に容易にメンテナンスが可能となる。また、シール材９により密閉度が高められているため、脱臭フィルタ８に画像形成装置本体１内で発生したトナーやオゾン等の臭気成分が確実に吸着される。 In this embodiment, a detachable deodorizing filter 8 is attached via a sealing material 9. Therefore, maintenance can be easily performed when the odor removal filter 8 reaches the end of its life. Further, since the sealing degree is enhanced by the sealing material 9, odor components such as toner and ozone generated in the image forming apparatus main body 1 are reliably adsorbed to the deodorizing filter 8.
さらに本実施例では、着脱可能な防塵フィルタ６がシール材７を介して取り付けられているため、防塵フィルタ６がメンテナンス時期に達した時に容易にメンテナンスが可能となる。また、シール材９により密閉度が高められているため、防塵フィルタ６に画像形成装置本体１内で発生した飛散トナーや粉塵が確実に吸着される。 Further, in the present embodiment, the removable dustproof filter 6 is attached via the seal material 7, so that maintenance can be easily performed when the dustproof filter 6 reaches the maintenance time. Further, since the sealing degree is enhanced by the sealing material 9, the scattered toner and dust generated in the image forming apparatus main body 1 are reliably adsorbed to the dustproof filter 6.
＜実施例２＞
図２は本発明の実施例２に係る正面図である。実施例１に対して、脱臭フィルタ８に流れる気流が均一になるように、脱臭フィルタ８の上流側に、排気ダクト３の上部コーナー部に角度約４５°の整流リブ１２、中心部に円形の整流リブ１１、下部にはV字形状に配置されたた整流リブ１０が形成されている。
<Example 2>
FIG. 2 is a front view according to Embodiment 2 of the present invention. Compared to the first embodiment, the rectifying ribs 12 having an angle of about 45 ° are formed at the upper corner portion of the exhaust duct 3 on the upstream side of the deodorizing filter 8 so that the airflow flowing through the deodorizing filter 8 is uniform, and the center portion is circular A rectifying rib 10 arranged in a V shape is formed at the lower portion of the rectifying rib 11.
本実施例の機能、動作について説明する。排気ファン４から排気された気流（やはり軸流ファンなので、その中心部は気流の流れが弱い特性がある）、排気ダクト３内部にV字形状に配置された整流リブ１０よって脱臭フィルタ８へ均一に分流され、脱臭フィルタ８の吸着面が均一に有効利用される。また、排気効率を向上させるため、気流の流れが弱い中心部には気流を流さないための円形の整流リブ１１によって排気効率が高まる。さらに、排気ダクト３内部のコーナー部に渦が発生するのを防止するための整流リブ１２によってさらに排気効率が高まる。 The function and operation of this embodiment will be described. Airflow exhausted from the exhaust fan 4 (again, it is an axial fan, so the airflow at the center is weak), and evenly to the deodorizing filter 8 by the rectifying rib 10 arranged in a V shape inside the exhaust duct 3 The adsorption surface of the deodorizing filter 8 is uniformly and effectively used. Further, in order to improve the exhaust efficiency, the exhaust current is enhanced by the circular rectifying ribs 11 for preventing the airflow from flowing in the central portion where the airflow is weak. Further, the exhaust efficiency is further enhanced by the rectifying rib 12 for preventing the vortex from being generated at the corner portion inside the exhaust duct 3.
＜実施例３＞
図３は本発明の実施例３に係る正面図である。図５は、排気ダクト３を画像形成装置本体１に固定するための口形状の板部材１４である。この板部材１４の一方の面に粘着部材（図示を省略する）が形成され、もう一方の面にはシール材１６とマジックテープ（登録商標）１５が形成されている。
<Example 3>
FIG. 3 is a front view according to Embodiment 3 of the present invention. FIG. 5 shows a mouth-shaped plate member 14 for fixing the exhaust duct 3 to the image forming apparatus main body 1. An adhesive member (not shown) is formed on one surface of the plate member 14, and a sealing material 16 and Velcro (registered trademark) 15 are formed on the other surface.
本実施例の板部材１４の機能、動作について説明すると、臭気除去フィルタの設定のない製品に後付けで臭気除去フィルタを取り付ける場合、口形状板部材１４の一方の面に形成された粘着部材により口形状板部材１４を製品排気口の周囲に貼り付けることで、製品側の臭気除去フィルタの着脱可能な固定構造が容易に作ることができる。 The function and operation of the plate member 14 according to the present embodiment will be described. When the odor removal filter is attached to a product that does not have an odor removal filter as a retrofit, the adhesive member formed on one surface of the mouth-shaped plate member 14 is used for the mouth. By attaching the shape plate member 14 around the product exhaust port, a detachable fixing structure of the odor removal filter on the product side can be easily made.
