Description

本考案は、乾燥設備等に設置され乾燥設備等の内部の湿気を外部に排出するための排気装置に係る技術分野に属する。   The present invention belongs to a technical field related to an exhaust device that is installed in a drying facility or the like and discharges moisture inside the drying facility or the like to the outside.

一般的に、乾燥設備等では、乾燥を促進するために内部の湿気を外部に排出するための排気装置が設置される。この排気装置には、乾燥設備等の内部の温度が高く湿度が高い場合に開放され、乾燥設備等の内部の温度が低く湿度が低い場合に閉鎖されるように、乾燥設備等の内部，外部を連通，遮断する開閉ダンパが備えられる。   Generally, in a drying facility or the like, an exhaust device for discharging internal moisture to the outside is installed in order to promote drying. This exhaust system is open when the internal temperature of the drying equipment is high and the humidity is high, and is closed when the internal temperature of the drying equipment is low and the humidity is low. Opening and closing dampers are provided to communicate and block.

従来、開閉ダンパを備えた排気装置としては、例えば、特許文献１に記載のものが知られている。   Conventionally, as an exhaust device provided with an open / close damper, for example, one disclosed in Patent Document 1 is known.

特許文献１には、乾燥設備等に接続された排気筒の内部にソレノイドで開閉駆動される開閉ダンパが取付けられた排気装置が記載されている。   Patent Document 1 describes an exhaust device in which an open / close damper that is driven to open and close by a solenoid is attached inside an exhaust pipe connected to a drying facility or the like.

特許文献１に係る排気装置は、ソレノイドの作動（励磁）によって開閉ダンパが迅速に開閉駆動されるものである。   In the exhaust device according to Patent Document 1, the opening / closing damper is rapidly opened / closed by actuation (excitation) of a solenoid.

特開２００４−８６４３号公報Japanese Patent Laid-Open No. 2004-8643

特許文献１に係る排気装置では、開閉ダンパの開閉駆動源としてソレノイドを使用することから、開閉ダンパを自動的に開閉させようとすると温度センサ，コントローラ等が必要になるため、製造コストが高くなるという問題点がある。   In the exhaust device according to Patent Document 1, since a solenoid is used as an opening / closing drive source of the opening / closing damper, a temperature sensor, a controller, and the like are required when the opening / closing damper is automatically opened / closed. There is a problem.

本考案は、このような問題点を考慮してなされたもので、製造コストを高めることなく開閉ダンパを自動的に開閉させることのできる排気装置を提供することを課題とする。   The present invention has been made in consideration of such problems, and an object of the present invention is to provide an exhaust device that can automatically open and close the open / close damper without increasing the manufacturing cost.

前述の課題を解決するため、本考案では、乾燥設備等に接続された排気筒の内部に開閉ダンパが取付けられた排気装置において、開閉ダンパを閉鎖方向に弾圧付勢する閉鎖用バネ材と、開閉ダンパを開放方向に弾圧付勢する開放用バネ材とを備え、開放用バネ材は高温時に閉鎖用バネ材の弾圧に抗して開閉ダンパを開放させるように変形する形状記憶合金で形成されていることを特徴とする手段を採用する。   In order to solve the above-described problems, in the present invention, in an exhaust device in which an open / close damper is attached to an inside of an exhaust pipe connected to a drying facility or the like, a closing spring material that elastically biases the open / close damper in a closing direction; And an opening spring material that elastically biases the opening / closing damper in the opening direction. The means characterized by the above is adopted.

この手段では、温度変化で自然に変形する形状記憶合金で形成された開放用バネ材によって開閉ダンパを開閉駆動することで、特許文献１に係る排気装置における温度センサ，コントローラ等が不要になる。   With this means, the temperature sensor, controller, and the like in the exhaust device according to Patent Document 1 are not required by opening and closing the opening and closing damper with the opening spring material formed of a shape memory alloy that is naturally deformed by a temperature change.

また、本考案では、開放用バネ材は高温時に軸長が伸張して弾性が発揮され低温時に弾性が低減されるコイルスプリングとされ軸長の伸張方向を開閉ダンパの方向へ規制するガイドシャフトが挿通されていることを特徴とする手段を採用する。   Further, in the present invention, the opening spring material is a coil spring whose axial length is extended to exhibit elasticity at high temperatures and reduced in elasticity at low temperatures, and a guide shaft that restricts the extension direction of the axial length toward the opening / closing damper. A means characterized by being inserted is adopted.

この手段では、開放用バネ材として直線的に変形するコイルスプリングが選択されることで、開閉ダンパを開閉駆動するための開放用バネ材の動作域が小さくなる。   In this means, a linearly deforming coil spring is selected as the opening spring material, so that the operating range of the opening spring material for driving the opening / closing damper is reduced.

また、本考案では、開閉ダンパは排気筒の軸方向と直交する方向に対して傾斜して閉鎖されることを特徴とする手段を採用する。   In the present invention, the open / close damper is closed with an inclination with respect to a direction orthogonal to the axial direction of the exhaust stack.

この手段では、開閉ダンパが傾斜して閉鎖されることで、短い開閉軌跡で大きな開放角度を構成することができる。   With this means, the opening / closing damper is inclined and closed, so that a large opening angle can be formed with a short opening / closing locus.

また、本考案では、開閉ダンパは排気筒の外部から開閉状態を目視することのできる目印が設けられていることを特徴とする手段を採用する。   In the present invention, the open / close damper employs means characterized in that a mark that allows the open / close state to be visually observed from the outside of the exhaust pipe is provided.

この手段では、開閉ダンパに開閉状態を目視することのできる目印が設けられることで、排気筒の外部から一見して開閉ダンパの開閉状態を把握することができる。   In this means, the open / close damper is provided with a mark that allows the open / close state to be visually observed, so that the open / close state of the open / close damper can be grasped at a glance from the outside of the exhaust stack.

本考案に係る排気装置は、温度変化で自然に変形する形状記憶合金で形成された開放用バネ材によって開閉ダンパを開閉駆動することで、温度センサ，コントローラ等が不要になるため、製造コストを高めることなく開閉ダンパを自動的に開閉させることができる効果がある。   Since the exhaust device according to the present invention drives the open / close damper with an opening spring material made of a shape memory alloy that is naturally deformed by a temperature change, a temperature sensor, a controller, and the like are not required. There is an effect that the opening and closing damper can be automatically opened and closed without increasing it.

以下、本考案に係る排気装置を実施するための形態を図面に基づいて説明する。   EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the exhaust apparatus which concerns on this invention is demonstrated based on drawing.

この形態では、熱風で食器類を乾燥させたり消毒保管したりする食器類乾燥装置，食器類消毒保管装置からなる乾燥設備等Ｄへの設置に好適なものを示してある。   In this embodiment, a tableware drying device that dries and disinfects and stores dishes with hot air, a drying facility that includes a tableware disinfection storage device, and the like that are suitable for installation in D are shown.

この形態は、図１に示すように、乾燥設備等Ｄの天部に縦型に設置される排気筒１に受座２，開閉ダンパ３，閉鎖用部材４，開放用部材５が取付けられている。   In this embodiment, as shown in FIG. 1, a seat 2, an open / close damper 3, a closing member 4, and an opening member 5 are attached to an exhaust pipe 1 installed vertically on the top of a drying facility D or the like. Yes.

排気筒１は、乾燥設備等Ｄの天部に立上げられるようにして接続され、方形の筒形に形成された本体部１１が乾燥設備等Ｄの内部，外部を連通して湿気Ｗの排気路を構成するものである。本体部１１の下部には、乾燥設備等Ｄへの接続のための取付用フランジ１２が張り出して設けられている。本体部１１の上部は、上端口がゴミ等の侵入を防止するために庇形の天板１３で閉塞され、天板１３の下位にある側面部に細幅の排気口１４が開口されている。また、本体部１１の側部の下方寄りには、丸孔からなる複数個の覗孔１５が穿孔されている。また、本体部１１の側部の下方寄りの覗孔１５が穿孔された面と直交する面の隅部には、スリット状の窓１６が開口されている（図３参照）。   The exhaust cylinder 1 is connected so as to be raised at the top of the drying equipment D or the like, and the main body 11 formed in a rectangular cylinder communicates the inside and the outside of the drying equipment D to exhaust the moisture W. It constitutes a road. At the lower part of the main body 11, a mounting flange 12 for connecting to a drying facility D or the like is provided so as to protrude. An upper end of the upper portion of the main body 11 is closed with a bowl-shaped top plate 13 to prevent intrusion of dust and the like, and a narrow exhaust port 14 is opened at a side surface below the top plate 13. . Further, a plurality of viewing holes 15 made of round holes are drilled near the lower side of the side of the main body 11. In addition, slit-like windows 16 are opened at the corners of the surface perpendicular to the surface in which the viewing hole 15 near the lower side of the main body 11 is perforated (see FIG. 3).

受座２は、方形の窓枠形状に形成され排気筒１の本体部１１の内部の下方寄り（排気筒１の覗孔１５，窓１６よりも下方）に取付け固定されている。この受座２は、図１（Ａ）に示すように、排気筒１の本体部１１の軸方向と直交する方向に対して約２０度の角度θで傾斜されている。なお、この受座２の両端部は、排気筒１の本体部１１の内壁に沿って上方，下方に延長されて略コ字型を呈し、開閉ダンパ３，開放用部材５の取付けに利用されている。   The receiving seat 2 is formed in the shape of a rectangular window frame, and is fixedly attached to the lower side of the inside of the main body 11 of the exhaust tube 1 (below the viewing hole 15 and the window 16 of the exhaust tube 1). As shown in FIG. 1A, the seat 2 is inclined at an angle θ of about 20 degrees with respect to a direction orthogonal to the axial direction of the main body 11 of the exhaust stack 1. Both end portions of the seat 2 extend upward and downward along the inner wall of the main body 11 of the exhaust tube 1 to form a substantially U-shape, and are used for mounting the opening / closing damper 3 and the opening member 5. ing.

開閉ダンパ３は、受座２の上方に延長された部分で排気筒１の本体部１１の内壁に固定された平板な取付座３１と、受座２の開口面よりも広い面積の開閉板３２と、取付座３１，開閉板３２との間に取付けられたヒンジ３３とからなる。開閉板３２の平板な板形の本体部３２ａの一辺（ヒンジ３３が取付けられた辺と直交する辺）には、ほぼ９０度上方に屈曲された補強片３２ｂが設けられている。開閉板３２の補強片３２ｂのヒンジ３３側の端部には、舌片形の突片３２ｃが形成されている。この開閉板３２の突片３２ｃは、開閉ダンパ３の開閉の際に、排気筒１の窓１６から出没する。開閉板３２のほぼ中央には、長軸がヒンジ３３方向に位置し端軸が補強片３２ｂ方向に位置する長孔３２ｄが穿孔されている。   The opening / closing damper 3 includes a flat mounting seat 31 fixed to the inner wall of the main body 11 of the exhaust stack 1 at a portion extending above the receiving seat 2, and an opening / closing plate 32 having a larger area than the opening surface of the receiving seat 2. And a hinge 33 mounted between the mounting seat 31 and the opening / closing plate 32. On one side of the flat plate-shaped main body portion 32a of the opening / closing plate 32 (side orthogonal to the side on which the hinge 33 is attached), a reinforcing piece 32b bent upward by approximately 90 degrees is provided. A tongue-shaped projecting piece 32c is formed at the end of the reinforcing piece 32b of the opening / closing plate 32 on the hinge 33 side. The projecting piece 32 c of the opening / closing plate 32 appears and disappears from the window 16 of the exhaust tube 1 when the opening / closing damper 3 is opened / closed. In the center of the opening / closing plate 32, a long hole 32d having a long axis positioned in the direction of the hinge 33 and an end shaft positioned in the direction of the reinforcing piece 32b is formed.

閉鎖用部材４は、開閉ダンパ３のヒンジ３３に組込まれたトーションコイルスプリング等の閉鎖用バネ材からなる。この閉鎖用部材４は、開閉ダンパ３の開閉板３２を受座２に押付けるように弾圧する。   The closing member 4 is made of a closing spring material such as a torsion coil spring incorporated in the hinge 33 of the opening / closing damper 3. The closing member 4 compresses the opening / closing plate 32 of the opening / closing damper 3 so as to press it against the seat 2.

開放用部材５は、受座２の下方に延長された部分で排気筒１の本体部１１の内壁に固定されて突出されたカップ形の取付座５１と、取付座５１に挿通され開閉ダンパ３の開閉板３２の長孔３２ｄに貫通されてさらに上方へ延びたガイドシャフト５２と、ガイドシャフト５２の下端部に取付けられガイドシャフト５２を取付座５１に抜止めする抜止ピン５３と、ガイドシャフト５２に嵌挿されてガイドシャフト５２の取付座５１との接触摩擦を低減するワッシャ５４と、開閉ダンパ３の開閉板３２の下方でガイドシャフト５２に嵌挿されてた開放用バネ材５５と、ガイドシャフト５２に嵌挿されてガイドシャフト５２の開閉ダンパ３の開閉板３２の長孔３２ｄとの接触摩擦を低減するワッシャ５６と、ガイドシャフト５２の上端部に取付けられガイドシャフト５２からワッシャ５６を抜止めする抜止ピン５７とからなる。開放用バネ材５５は、高温時に軸長が伸張するニッケル−チタン系の形状記憶合金で形成されたコイルスプリングからなる。この開放用バネ材５５は、ニッケル−チタン系の形状記憶合金の特性から、高温時に弾性を強力に発揮し低温時に弾性を低減する機能を有している。この開放用バネ材５５の高温時に弾性は、閉鎖用バネ材４の弾性よりも強力になるように設定されている。   The opening member 5 includes a cup-shaped mounting seat 51 that is fixedly protruded from the inner wall of the main body 11 of the exhaust stack 1 at a portion extending below the receiving seat 2, and an opening / closing damper 3 that is inserted through the mounting seat 51. A guide shaft 52 that extends through the elongated hole 32d of the opening / closing plate 32 and extends further upward, a retaining pin 53 that is attached to the lower end portion of the guide shaft 52 and prevents the guide shaft 52 from being attached to the mounting seat 51, and the guide shaft 52 A washer 54 that reduces contact friction with the mounting seat 51 of the guide shaft 52, a release spring material 55 that is inserted into the guide shaft 52 below the opening / closing plate 32 of the opening / closing damper 3, and a guide A washer 56 that is fitted on the shaft 52 to reduce contact friction with the elongated hole 32d of the opening / closing plate 32 of the opening / closing damper 3 of the guide shaft 52, and is attached to the upper end of the guide shaft 52. Consisting retaining pin 57 for retaining fit the washer 56 from id shaft 52. The release spring material 55 is made of a coil spring formed of a nickel-titanium shape memory alloy whose axial length is extended at a high temperature. This release spring material 55 has a function of strongly exhibiting elasticity at high temperatures and reducing elasticity at low temperatures due to the characteristics of the nickel-titanium shape memory alloy. The elasticity of the opening spring material 55 is set to be stronger than that of the closing spring material 4 at a high temperature.

この形態によると、乾燥設備等Ｄの内部の温度が低い場合（食器類乾燥装置，食器類消毒保管装置からなる乾燥設備等Ｄは通常湿度が低くなっている）には、図１（Ａ）に示すように、開放用部材５の開放用バネ材５５の軸長が短縮される。従って、開閉ダンパ３は、開閉板３２が閉鎖用部材４の弾性で受座２に押付けられることで閉鎖されることになる。このとき、弾性が低減した開放用バネ材５５は、閉鎖用部材４の弾性によって軸長が収縮される。開閉ダンパ３が閉鎖されると、乾燥設備等Ｄの内部，外部が遮断され乾燥設備等Ｄの内部への虫，ゴミ等の侵入を防止することができる。   According to this embodiment, when the temperature inside the drying facility D is low (the drying facility D including the tableware drying device and the tableware disinfection storage device is usually low in humidity), FIG. As shown, the axial length of the opening spring member 55 of the opening member 5 is shortened. Therefore, the open / close damper 3 is closed when the open / close plate 32 is pressed against the seat 2 by the elasticity of the closing member 4. At this time, the shaft length of the opening spring material 55 with reduced elasticity is contracted by the elasticity of the closing member 4. When the open / close damper 3 is closed, the inside and outside of the drying facility D can be shut off and insects, dust, etc. can be prevented from entering the interior of the drying facility D.

逆に、乾燥設備等Ｄの内部の温度が高い場合（食器類乾燥装置，食器類消毒保管装置からなる乾燥設備等Ｄは通常湿度が高くなっている）には、図１（Ｂ）に示すように、開放用部材５の開放用バネ材５５の軸長が伸張される。従って、開閉ダンパ３は、開閉板３２が閉鎖用部材４の弾性に抗する開放用部材５の開放用バネ材５５の弾性で受座２から押上げられることで開放される。開閉ダンパ３が開放されると、乾燥設備等Ｄの内部，外部が連通され乾燥設備等Ｄの内部の湿気Ｗを外部に上昇排出させることができる。   Conversely, when the temperature inside the drying facility D is high (the drying facility D including the tableware drying device and the tableware disinfection storage device has a high humidity), it is shown in FIG. As described above, the axial length of the opening spring member 55 of the opening member 5 is extended. Accordingly, the opening / closing damper 3 is opened by the opening / closing plate 32 being pushed up from the seat 2 by the elasticity of the opening spring member 55 of the opening member 5 that resists the elasticity of the closing member 4. When the open / close damper 3 is opened, the inside and the outside of the drying facility etc. D are communicated, and the moisture W inside the drying facility etc. D can be raised and discharged to the outside.

この開閉ダンパ３の開閉は、温度変化にともなう開放用部材５の開放用バネ材５５の変形で自動的に駆動される。従って、特許文献１に係る排気装置における温度センサ，コントローラ等が不要になるため、製造コストを低減することができる。   The opening / closing of the opening / closing damper 3 is automatically driven by the deformation of the opening spring member 55 of the opening member 5 accompanying the temperature change. Therefore, the temperature sensor, the controller, and the like in the exhaust device according to Patent Document 1 are not necessary, and the manufacturing cost can be reduced.

この開放用部材５の開放用バネ材５５の変形については、６０℃で軸長が伸張し５０℃で軸長が収縮するように設定するのが好ましい。なお、開閉ダンパ３の開閉については、徐動となって特許文献１に係る排気装置のような迅速性を期待することができない。ただし、食器類乾燥装置，食器類消毒保管装置からなる乾燥設備等Ｄでは、長時間の処理が行われて頻繁に開閉ダンパ３が開閉されるわけではないので、全く支障は生じない。   The deformation of the opening spring member 55 of the opening member 5 is preferably set so that the axial length is extended at 60 ° C. and the axial length is contracted at 50 ° C. Note that the opening / closing of the open / close damper 3 is slow and cannot be expected to be as quick as the exhaust device according to Patent Document 1. However, in the drying equipment D including the tableware drying device and the tableware disinfection storage device, since the long-time processing is not performed and the opening / closing damper 3 is not frequently opened and closed, no trouble occurs.

さらに、この形態によると、開放用部材５の開放用バネ材５５として直線的に変形するコイルスプリングが選択されることで、開閉ダンパ３を開閉駆動するための開放用バネ材５５の動作域を小さくすることができ、装置全体の小型化が可能になる。また、開放用部材５のコイルスプリングからなる開放用バネ材５５の軸長の伸張がガイドシャフト５２に案内されるため、開放用バネ材５５の変形が捻れ等を生ずることなく正確に実行される。   Further, according to this embodiment, a coil spring that linearly deforms is selected as the opening spring material 55 of the opening member 5, so that the operating range of the opening spring material 55 for opening and closing the opening / closing damper 3 is increased. It is possible to reduce the size of the entire apparatus. Further, since the extension of the axial length of the opening spring material 55 made of the coil spring of the opening member 5 is guided by the guide shaft 52, the deformation of the opening spring material 55 is accurately executed without causing twisting or the like. .

また、開閉ダンパ３が閉鎖時に受座２によって傾斜されているため、開閉ダンパ３を短い開閉軌跡で大きな開放角度を構成させることができる。   Further, since the opening / closing damper 3 is inclined by the seat 2 when closed, the opening / closing damper 3 can be configured to have a large opening angle with a short opening / closing locus.

また、開閉ダンパ３が開放されると、開閉ダンパ３の開閉板３２の突片３２ｃが排気筒１の窓１６から突出されるため、開閉ダンパ３の開閉状態を目視することのできる目印が設けられることになって、排気筒１の外部から一見して開閉ダンパ３の開閉状態を把握することができる。同様に、排気筒１の覗孔１５からの開閉ダンパ３の開閉状態を把握することもできる。   When the open / close damper 3 is opened, the projecting piece 32c of the open / close plate 32 of the open / close damper 3 protrudes from the window 16 of the exhaust stack 1, so that the open / close state of the open / close damper 3 can be visually observed. Thus, the open / close state of the open / close damper 3 can be grasped at a glance from the outside of the exhaust stack 1. Similarly, the open / close state of the open / close damper 3 from the viewing hole 15 of the exhaust tube 1 can be grasped.

以上、図示した形態の外に、排気筒１を乾燥設備等Ｄの側部に接続する横型に構成することも可能である。   As described above, in addition to the illustrated form, the exhaust pipe 1 can be configured as a horizontal type connected to the side of the drying equipment D or the like.

本考案に係る排気装置は、食器類乾燥装置，食器類消毒保管装置以外の広範な乾燥設備等Ｄへの設置が可能である。また、小型から大型まで乾燥設備等Ｄの装置規模に対応して大きさを変更することが可能である。   The exhaust device according to the present invention can be installed in a wide range of drying facilities D other than the tableware drying device and the tableware disinfection storage device. Moreover, it is possible to change a magnitude | size corresponding to the apparatus scales, such as drying equipment, from small to large.
