Description
本発明は、電子写真方式の複写機やプリンタ等の画像形成装置に用いられる空気清浄装置及びこの空気清浄装置を備える画像形成装置に関する。 The present invention relates to an air cleaning device used in an image forming apparatus such as an electrophotographic copying machine or a printer, and an image forming apparatus including the air cleaning device.
近年、建物の気密性が向上したこともあって、室内に設置されているプリンタ、複写機等の各種事務機器から発生するオゾンや窒素酸化物（ＮＯｘ：ＮＯ、ＮＯ２等）、揮発性有機化合物（ＶＯＣ）等の排出物質に対する関心が高まっている。
各種事務機器から外部に排出されるオゾン、窒素酸化物及び揮発性有機化合物は装置外に排出されると、人体等に悪影響を及ぼすことがあり、またその臭気により人に不快感を与えることがある。そのため、これら排出物質を吸着除去するフィルタが事務機器内に一般的に設置されている。
Recently, also a possible airtight buildings is improved, a printer that is installed in a room, a copying machine such as ozone and nitrogen oxide generated from a variety of office machines (NOx: NO, NO 2, etc.), volatile organic There is a growing interest in emissions such as compounds (VOC).
Ozone, nitrogen oxides, and volatile organic compounds discharged to the outside from various office equipment may adversely affect the human body, etc., and may cause discomfort to humans due to their odor. is there. Therefore, a filter for adsorbing and removing these exhausted substances is generally installed in office equipment.
しかしながら、フィルタによる吸着除去方法では、これら排出物質を吸着するとフィルタの吸着性能は短時間で低下してしまい、ユーザやサービスマンがフィルタを頻繁に交換しなければならないという問題があった。また、フィルタによる排出物質除去効率を向上させるために、フィルタのメッシュを細かくしたりフィルタの厚みを厚くしたりしてフィルタの表面積を増大させると、フィルタの圧力損失が増大して容量の大きいファンを取付ける必要が生じ、装置の製造コストが高くなる。また、同時に消費電力も増大し、更にファンによる騒音が大きくなる虞がある。 However, the adsorption removal method using a filter has a problem that if these exhausted substances are adsorbed, the adsorption performance of the filter deteriorates in a short time, and the user or serviceman must frequently replace the filter. In addition, if the filter surface area is increased by reducing the filter mesh or increasing the filter thickness in order to improve the exhaust material removal efficiency by the filter, the pressure loss of the filter increases and the fan with a larger capacity. The manufacturing cost of the apparatus becomes high. At the same time, the power consumption increases and the noise from the fan may increase.
また光触媒フィルタを用いてこれら排出物質を除去する方法が知られている。しかしこの方法では、紫外線ランプからの紫外線光が光触媒に照射されている間しか排出物質を分解除去できないという問題があった。 In addition, a method for removing these emission substances using a photocatalytic filter is known. However, this method has a problem in that the discharged substances can be decomposed and removed only while the photocatalyst is irradiated with ultraviolet light from the ultraviolet lamp.
そこで特許文献１には、光触媒層が形成された光触媒保持体と、蓄光顔料層が形成された蓄光顔料保持体と、光触媒層及び蓄光顔料層に紫外線光を照射する光源とを備え、光源及び蓄光顔料層の少なくとも一方からの紫外線光によって、オゾンと窒素酸化物、揮発性有機化合物を光触媒層で分解することを特徴とする空気清浄機構が開示されている。
しかしながら、この特許文献１の開示技術は、オゾン、窒素酸化物、揮発性有機化合物を光触媒層で分解する技術であるため、排出物質除去効率の向上という点においては、充分ではない。
Therefore, Patent Document 1 includes a photocatalyst holder in which a photocatalyst layer is formed, a photocatalyst pigment holder in which a phosphorescent pigment layer is formed, and a light source that irradiates the photocatalyst layer and the phosphorescent pigment layer with ultraviolet light. An air cleaning mechanism is disclosed in which ozone, nitrogen oxides, and volatile organic compounds are decomposed by a photocatalyst layer with ultraviolet light from at least one of the phosphorescent pigment layers.
However, since the disclosed technique of Patent Document 1 is a technique for decomposing ozone, nitrogen oxides, and volatile organic compounds with a photocatalyst layer, it is not sufficient in terms of improving emission material removal efficiency.
本発明は、上記した従来技術の問題点を解決すべくなされたものであって、機器内で発生したオゾン、窒素酸化物及び揮発性化合物を長期間に亘って安定して除去でき、構成要素の交換や補充を減らすことができ、発生する物質を従来よりも更に効率よく除去することができる空気清浄装置及びこの空気清浄機を備える画像形成装置を提供するものである。 The present invention has been made to solve the above-described problems of the prior art, and can stably remove ozone, nitrogen oxides, and volatile compounds generated in equipment over a long period of time.

Active compounds can be removed stably over a long period of time, and the ability to irradiate ultraviolet rays does not drop in a short period of time, so the replacement and replenishment of components can be reduced, and by combining ultraviolet irradiation means and heating means In addition, it is possible to provide an air cleaning device that can decompose and remove ozone, nitrogen oxides, and volatile compounds more efficiently.

図1は、本発明に係る空気清浄装置を備える画像形成装置の概略図である。
図１に示すように、本発明に係る画像形成装置（１００）は、給紙部（１０１）、画像形成部（１０２）、定着部（１０３）及び空気清浄装置（１０４）を備えている。
主に画像形成部（１０２）及び定着部（１０３）にて発生するオゾン、窒素酸化物及び揮発性有機化合物を含むガスは、空気清浄装置（１０４）を通して装置外に排出される。
FIG. 1 is a schematic view of an image forming apparatus including an air cleaning device according to the present invention.
As shown in FIG. 1, an image forming apparatus (100) according to the present invention includes a paper feeding unit (101), an image forming unit (102), a fixing unit (103), and an air cleaning device (104).
Gases containing ozone, nitrogen oxides, and volatile organic compounds mainly generated in the image forming unit (102) and the fixing unit (103) are discharged out of the apparatus through the air cleaning device (104).
図２は、空気清浄装置の概略図である。
図２に示すように、空気清浄装置（１０４）は、ガスを排気口（４）へ案内するための排気ダクト（１）、ガスを装置外へ送るためのファン（２）、及びガスが装置外に排出される前にガス中のオゾン、窒素酸化物及び揮発性有機化合物を分解除去するための分解装置（３）を備えている。
ガスは、ファン（２）により排気ダクト（１）内を排気口（４）に向かって流れ、分解装置（３）にてガスに含まれるオゾン、窒素酸化物及び揮発性有機化合物は分解される。分解されたガスは排気口（４）から装置外に排出される。
FIG. 2 is a schematic view of the air cleaning device.
As shown in FIG. 2, the air cleaning device (104) includes an exhaust duct (1) for guiding gas to an exhaust port (4), a fan (2) for sending gas to the outside of the device, and a gas device. A decomposition device (3) is provided for decomposing and removing ozone, nitrogen oxides and volatile organic compounds in the gas before being discharged outside.
The gas flows through the exhaust duct (1) toward the exhaust port (4) by the fan (2), and ozone, nitrogen oxides and volatile organic compounds contained in the gas are decomposed by the decomposition device (3). . The decomposed gas is discharged out of the apparatus through the exhaust port (4).
図３は、分解装置の概略図である。
図３に示すように、分解装置（３）は、加熱手段（３１）と紫外線照射手段（３２）を備える。加熱手段（３１）と紫外線照射手段（３２）は、排気ダクト（１）の上壁部と下壁部に対向して設置されている。図示例では加熱手段（３１）が上壁部に配置されているが、どちらが上壁部に設置されても良い。また、排気ダクトの左右の壁部に対向して配置してもよい。紫外線照射手段（３２）は、図示の如く加熱手段（３１）の直下又は直上に設置されるのが分解除去効率の点から望ましいが、加熱手段（３１）の下流側直後に設置されても良い。
ファン（２）によって運ばれたガスは、加熱手段（３１）によって３００℃以上に加熱される。加熱によりガス中のオゾン、窒素酸化物及び揮発性有機化合物は分解されやすい状態となる。加熱温度を３００℃以上とする理由は、３００℃未満であるとオゾン、窒素酸化物及び揮発性有機化合物の分解除去効率が低下するからである。また、加熱のみでオゾン、窒素酸化物及び揮発性有機化合物を分解しようとすると６００〜７００℃で加熱する必要があるが、分解手段として紫外線照射と併用することにより、それほどの高温加熱は必要なくなる。
加熱手段（３１）としては、気体用加熱ヒータが用いられる。具体的には、発熱線に電気を流すことによる抵抗加熱によるヒータ、及びその応用電熱装置が好適に用いられる。また、遠赤外線等の放射による加熱であってもよい。形状はパネル状が望ましい。
加熱手段（３１）による加熱と同時に、もしくは加熱手段（３１）による加熱の後、そのガスは紫外線照射手段（３２）により、１８５〜２５４ｎｍの波長の紫外線が照射され、ガスに含まれるオゾン、窒素酸化物及び揮発性有機化合物は分解される。紫外線の波長を１８５〜２５４ｎｍとする理由は、１８５ｎｍ未満又は２５４ｎｍを超える場合、オゾン、窒素酸化物及び揮発性有機化合物の分解除去効率が低下するからである。
紫外線照射手段（３２）は、紫外線光源として、発光管が棒状の低圧水銀ＵＶランプが好適に用いられる。
紫外線照射手段（３２）は、装置駆動時に紫外線を照射するように構成される。
FIG. 3 is a schematic view of the disassembling apparatus.
As shown in FIG. 3, the decomposition apparatus (3) includes a heating means (31) and an ultraviolet irradiation means (32). The heating means (31) and the ultraviolet irradiation means (32) are installed facing the upper wall portion and the lower wall portion of the exhaust duct (1). In the illustrated example, the heating means (31) is disposed on the upper wall, but either may be installed on the upper wall. Moreover, you may arrange | position facing the wall part on either side of an exhaust duct. As shown in the figure, it is desirable that the ultraviolet irradiation means (32) is disposed immediately below or directly above the heating means (31) from the viewpoint of decomposition and removal efficiency. However, the ultraviolet irradiation means (32) may be disposed immediately downstream of the heating means (31). .
The gas carried by the fan (2) is heated to 300 ° C. or higher by the heating means (31). Ozone, nitrogen oxides and volatile organic compounds in the gas are easily decomposed by heating. The reason why the heating temperature is set to 300 ° C. or higher is that if it is lower than 300 ° C., the decomposition and removal efficiency of ozone, nitrogen oxides, and volatile organic compounds decreases. Moreover, when ozone, nitrogen oxides, and volatile organic compounds are to be decomposed only by heating, it is necessary to heat at 600 to 700 ° C. However, by using together with ultraviolet irradiation as a decomposition means, heating at such a high temperature is not necessary. .
A gas heater is used as the heating means (31). Specifically, a heater by resistance heating by causing electricity to flow through the heating wire, and its applied electric heating device are preferably used. Further, heating by radiation such as far infrared rays may be used. The shape of the panel is desirable.
Simultaneously with heating by the heating means (31) or after heating by the heating means (31), the gas is irradiated with ultraviolet rays having a wavelength of 185 to 254 nm by the ultraviolet irradiation means (32), and ozone and nitrogen contained in the gas Oxides and volatile organic compounds are decomposed. The reason for setting the wavelength of ultraviolet light to 185 to 254 nm is that when it is less than 185 nm or exceeds 254 nm, the decomposition and removal efficiency of ozone, nitrogen oxides, and volatile organic compounds decreases.
For the ultraviolet irradiation means (32), a low-pressure mercury UV lamp having a rod-like arc tube is suitably used as an ultraviolet light source.
The ultraviolet irradiation means (32) is configured to irradiate ultraviolet rays when the apparatus is driven.
図４は、ヒートポンプ及び熱交換器を有する空気清浄装置の概略図である。
図４に示すように、排気ダクト（１）内には、第１熱交換器（５）がファン（２）の下流側且つ紫外線照射手段（３２）の上流側に設置され、第２熱交換器（６）が分解装置（３）及び第１熱交換器（５）の下流側に設置される。ヒートポンプ（７）が排気ダクト（１）外に設置される。ヒートポンプ（７）は、膨張弁（７１）、蒸発器（７２）、圧縮機（７３）及び凝縮器（７４）を備える。第１熱交換器（５）は凝縮器（７４）と接続され、第２熱交換器（６）は蒸発器（７２）と接続される。
ヒートポンプ（７）内を流れる冷媒は、膨張弁（７１）にて低温低圧の液体となり、その後蒸発器（７２）にて蒸発する際、気化熱として外気の熱を奪う。蒸発器（７２）と第２熱交換器（６）は接続されているので、加熱され高温となった排気ダクト（１）内のガスは第２熱交換器（６）によって熱を奪われ即ち冷却され、高温のガスが装置外に排出されるのを防止する。
蒸発器（７２）にて低温低圧の気体となった冷媒は、その後圧縮機（７３）にて高温高圧の気体となり、凝縮器にて凝縮する際、凝縮熱として外気へ熱を放出する。凝縮器（７４）と第１熱交換器（５）は接続されているので、ファン（２）によって運ばれたガスは、第１熱交換器（５）によって加熱される。この冷媒の凝縮熱は、第２熱交換器（６）にて加熱され高温となった排気ダクト（１）内のガスから奪った熱であり、この熱を利用して再び加熱の熱源として使用することで、加熱手段（３１）の電力を節減でき、コストを削減することができる。
FIG. 4 is a schematic view of an air cleaning device having a heat pump and a heat exchanger.
As shown in FIG. 4, in the exhaust duct (1), a first heat exchanger (5) is installed on the downstream side of the fan (2) and on the upstream side of the ultraviolet irradiation means (32). A vessel (6) is installed downstream of the cracking device (3) and the first heat exchanger (5). A heat pump (7) is installed outside the exhaust duct (1). The heat pump (7) includes an expansion valve (71), an evaporator (72), a compressor (73), and a condenser (74). The first heat exchanger (5) is connected to the condenser (74), and the second heat exchanger (6) is connected to the evaporator (72).
The refrigerant flowing in the heat pump (7) becomes a low-temperature and low-pressure liquid at the expansion valve (71), and then deprives the outside air as heat of vaporization when it evaporates in the evaporator (72). Since the evaporator (72) and the second heat exchanger (6) are connected, the gas in the exhaust duct (1) heated to a high temperature is deprived of heat by the second heat exchanger (6). It is cooled and prevents hot gas from being discharged out of the apparatus.
The refrigerant that has become a low-temperature and low-pressure gas in the evaporator (72) then becomes a high-temperature and high-pressure gas in the compressor (73), and releases heat to the outside air as condensation heat when condensing in the condenser. Since the condenser (74) and the first heat exchanger (5) are connected, the gas carried by the fan (2) is heated by the first heat exchanger (5). The heat of condensation of the refrigerant is the heat taken from the gas in the exhaust duct (1) that has been heated by the second heat exchanger (6) and becomes a high temperature, and is used again as a heat source for heating using this heat. By doing so, the electric power of a heating means (31) can be saved and cost can be reduced.
本発明は、電子写真方式のプリンタ、複写機、ファクシミリ等の、空気清浄装置を備えた画像形成装置に対して好適に利用される。 The present invention is suitably used for an image forming apparatus equipped with an air cleaning device, such as an electrophotographic printer, a copying machine, and a facsimile machine.
