Description

本発明は、洗浄用器具の技術分野に属する。本発明は、配管（特に排煙用ダクト）の洗浄用器具およびその洗浄方法に関するものである。   The present invention belongs to the technical field of cleaning instruments. The present invention relates to a cleaning instrument for piping (especially a duct for smoke exhaust) and a cleaning method thereof.

配管とは、液体、気体、粉体等の流体の輸送等のために取り付けられた管、チューブ、ホースのことをいう。通常、配管は、金属製または高分子樹脂製等の材質で、形状は角形、円形または楕円形の筒形状を有しており、直管、曲管（エルボ）、分岐管等を組み合わせて用いられる。このような配管は、ダクト（通風管）、水道管、排水管、ガス管、消火管等の様々な用途で、工場、店舗、家庭、屋外、地中、海中等のあらゆる場所に配設されている。これらの中でもダクトは、通常、気体を運ぶ管であり、主に建築物内の空調、換気、または排煙等の目的で配設されるものである。   The pipe means a pipe, a tube, or a hose attached for transporting a fluid such as liquid, gas, and powder. Normally, piping is made of metal or polymer resin, and has a cylindrical shape such as a square, circle, or ellipse, and is used in combination with straight pipes, bent pipes (elbows), branch pipes, etc. It is done. Such pipes are installed in various places such as factories, stores, homes, outdoors, underground, and underwater in various uses such as ducts (ventilating pipes), water pipes, drainage pipes, gas pipes, and fire extinguishing pipes. ing. Among these, the duct is usually a pipe that carries a gas, and is mainly disposed for the purpose of air conditioning, ventilation, or smoke emission in a building.

ダクトを配設し、空調、換気、および排煙等を行うことにより、建築物内部は快適な環境に保たれるが、その長期間の使用、または汚れた空気の輸送によりダクトの管の内壁には油や粉塵、付着物等の汚れが堆積していくことになる。このような汚れは、汚れた空気や煙を輸送するための排煙用ダクトの場合において特に問題となる。ダクト内の汚れの堆積は、結果として、ダクトの機能低下、そしてダクトの閉塞を引き起こす。ダクトが閉塞した場合、ダクトそのものを全て取り替える必要が生じることさえある。また、飲食店、例えば焼肉店の排煙用ダクトの場合、堆積された汚れには油分を含んでいるため、悪臭の発生や発火の恐れもある。   The interior of the building is maintained in a comfortable environment by installing a duct and performing air conditioning, ventilation, smoke exhaust, etc., but the inner wall of the duct tube due to its long-term use or transport of dirty air On the surface, dirt such as oil, dust, and deposits accumulates. Such contamination is particularly problematic in the case of smoke exhaust ducts for transporting dirty air and smoke. The accumulation of dirt in the duct results in reduced function of the duct and blockage of the duct. If the duct becomes blocked, it may even be necessary to replace the duct itself. In addition, in the case of smoke exhaust ducts at restaurants, for example, yakiniku restaurants, the accumulated dirt contains oil, so there is a risk of generation of malodors and ignition.

このようなダクト内の汚れの堆積による、ダクトの機能低下を避けるためには、定期的な清掃、または洗浄が必要不可欠である。しかし、通常は、内部に作業者が清掃器具を持ち込み、作業するにはダクトは開口が狭く、内部の清掃や洗浄は非常に困難である。従来、このようなダクトの清掃や洗浄の方法としては、例えば、汚れが軽度の場合には、水を流してその水圧で汚れを除去する方法、外部からブラシを挿入し、浮かせた粉塵を集塵機で吸い込む方法が挙げられ、また、汚れが酷い場合には、ダクトの内部に薬品や熱湯を流して汚れを溶解、剥離させる方法が挙げられる。しかし、水などの液体を用いて天井のダクトを洗浄すると部屋中が水浸しになるという問題がある。また、ダクトの入口付近に、例えば焼肉用テーブルがある場合、それを取り外して洗浄を行う必要がある。またダクトが折れ曲がっている場合には内部までの洗浄は困難である。   Periodic cleaning or cleaning is indispensable in order to avoid deterioration of the function of the duct due to accumulation of dirt in the duct. However, usually, an operator brings a cleaning tool inside, and the duct has a narrow opening for working, and it is very difficult to clean and clean the inside. Conventionally, as a method of cleaning and cleaning such ducts, for example, when dirt is light, a method of removing dirt by flowing water with the water pressure, a brush is inserted from the outside, and dust that floats is collected by a dust collector In the case where the dirt is severe, there is a method in which a chemical or hot water is poured inside the duct to dissolve and remove the dirt. However, there is a problem that if the ceiling duct is cleaned with a liquid such as water, the room is immersed in water. Moreover, when there is a grilled meat table near the entrance of the duct, for example, it is necessary to remove it and perform cleaning. Further, when the duct is bent, it is difficult to clean the inside.

特許文献１には、挿抜方向に沿った軸心周りに回転することにより、流体輸送管に接続された弁取付用の分岐管内を掃除し、分岐管内の流体を排出する機能を有する分岐管内掃除装置が開示されている。当該掃除用具の利点は管の内面から掻き落とされた物を、管内に残さず、排出管内流体とともに外部に排出できることにある。当該掃除装置は、流体輸送管に用いられるものであり、また、掃除具の軸は可撓性を有しない。   Patent Document 1 discloses a cleaning in a branch pipe that has a function of cleaning the inside of a branch pipe for valve attachment connected to a fluid transport pipe and discharging the fluid in the branch pipe by rotating around an axis along the insertion / extraction direction. An apparatus is disclosed. The advantage of the cleaning tool is that the material scraped off from the inner surface of the pipe can be discharged to the outside together with the fluid in the discharge pipe without leaving it in the pipe. The said cleaning apparatus is used for a fluid transport pipe, and the axis | shaft of a cleaning tool does not have flexibility.

特許文献２には、ダクト内面に強固に付着している塵芥を清掃するための空調ダクトノズルおよび空調ダクト清掃装置が開示されている。当該清掃装置は、高圧空気を導くホースの先端にシャフトを取り付け、シャフトの外周面に高圧空気を略半径方向に噴射する複数の噴射口を形成し、またカバーの内周面には羽根車を有する。当該清掃装置は、放出空気によって空調ダクトの内面の塵芥を浮き飛ばすとともに、ノズルの推進力を得ることができ、ノズルは空調ダクトの内壁面に沿って旋回しながら推進することで付着している塵芥を清掃することができる。しかし、当該清掃装置は高圧の空気によって吹き飛ばすことができる塵芥には有効であるが、強固に堆積した汚れを掻き落とす効果を有しない。   Patent Document 2 discloses an air-conditioning duct nozzle and an air-conditioning duct cleaning device for cleaning dust that is firmly attached to the inner surface of the duct. In the cleaning device, a shaft is attached to the tip of a hose that guides high-pressure air, a plurality of injection ports for injecting high-pressure air in a substantially radial direction are formed on the outer peripheral surface of the shaft, and an impeller is provided on the inner peripheral surface of the cover. Have. The cleaning device floats the dust on the inner surface of the air conditioning duct by the released air and can obtain the propulsive force of the nozzle, and the nozzle adheres by propelling while turning along the inner wall surface of the air conditioning duct. The dust can be cleaned. However, the cleaning device is effective for dust that can be blown away by high-pressure air, but does not have the effect of scraping off the accumulated dirt.

１．６ フレキシブル中空部材
本発明洗浄用器具は、前記可撓性中空部材が貫通する可撓性で伸縮可能なフレキシブル中空部材（以下、「フレキシブル中空部材」という。）を含む。かかるフレキシブル中空部材は、通常、管状であり、当該中空部材の長軸方向に、例えば蛇腹式（アコーディオン式）に収縮させることにより、伸長状態から収縮状態に縮めることができ、また逆に収縮状態から伸長状態に伸ばすことができる（図６（Ａ）、（Ｂ）参照）。フレキシブル中空部材は、配管洗浄後、可撓軸や可撓性中空部材といった部品、またはそれに加えてブラシを配管から回収する際に、収縮状態から伸長状態に伸ばすことにより、それら部品等をカバーすることができ、それらに付着した粉塵や油といった汚れの飛散、落下などを防止する機能を有する。 1.6 Flexible Hollow Member The cleaning instrument of the present invention includes a flexible and extendable flexible hollow member (hereinafter referred to as “flexible hollow member”) through which the flexible hollow member passes. Such a flexible hollow member is usually tubular, and can be contracted from an expanded state to a contracted state by contracting in the longitudinal direction of the hollow member, for example, an accordion type (accordion type). Can be extended to a stretched state (see FIGS. 6A and 6B). The flexible hollow member covers parts such as a flexible shaft and a flexible hollow member after the pipe is washed, or by extending the brush from the contracted state to the extended state when the brush is recovered from the pipe. It has a function of preventing the scattering and dropping of dirt such as dust and oil adhering to them.

フレキシブル中空部材の内径は、可撓性中空部材の外径より大きく、通常、配管のほぼ外径までである。フレキシブル中空部材の内径が配管の外径と同程度である場合、フレキシブル中空部材を配管に直接接続ないし固定することもできる。その際、ロープやベルト等の適当な補強部材で当該接続ないし固定を補強することができる。フレキシブル中空部材の径が、配管の径より小さい場合は、例えば、中空のジョイント部材を使用し、可撓性中空部材と配管とを接続することもできる。その接続において、ロープやベルト等の適当な補強部材で接続を補強（固定）することができる。フレキシブル中空部材を配管に直接またはジョイント部材を用いて接続することにより、一人でも、また片手でも容易にフレキシブル中空部材を収縮状態から伸長状態に伸ばすことができる。   The inner diameter of the flexible hollow member is larger than the outer diameter of the flexible hollow member, and is usually up to substantially the outer diameter of the pipe. When the inner diameter of the flexible hollow member is approximately the same as the outer diameter of the pipe, the flexible hollow member can be directly connected to or fixed to the pipe. At that time, the connection or fixation can be reinforced by an appropriate reinforcing member such as a rope or a belt. When the diameter of the flexible hollow member is smaller than the diameter of the pipe, for example, a hollow joint member can be used to connect the flexible hollow member and the pipe. In the connection, the connection can be reinforced (fixed) with an appropriate reinforcing member such as a rope or a belt. By connecting the flexible hollow member to the pipe directly or using a joint member, the flexible hollow member can be easily extended from the contracted state to the extended state by one person or one hand.

フレキシブル中空部材の伸長状態における長軸方向の長さとしては、可撓軸や可撓性中空部材の長さに応じて適宜選択しうるが、例えば、可撓性中空部材の分岐部（分岐管を用いる場合はその分岐部）からブラシの根元ないし先端までの長さを挙げることができる。また、それ以上であってもそれ以下であってもよい。また、フレキシブル中空部材の収縮状態における長軸方向の長さは、伸長状態の１／３〜１／２０の長さが適当であり、１／５〜１／２０の長さが好ましい。   The length in the major axis direction in the extended state of the flexible hollow member can be appropriately selected according to the length of the flexible shaft or the flexible hollow member.

（５）第５工程
本工程は、汚れを落としながら、または汚れを落とした後、その汚れを当該配管洗浄用器具の可撓性中空部材を通して前記吸引機で吸い取る工程である。
汚れを配管１０から掻き落としながら、または汚れを掻き落とした後、その汚れは本発明洗浄用器具Ａの可撓性中空部材４を通過して吸引機８によって吸い取られる。図１および図２の一例では、ブラシ６の根元に位置するところにあるノズル５が吸引機８の吸い取り口として機能し、そこから汚れが吸い取られる。吸い取られた汚れは、可撓性中空部材４を通って吸引機内部に蓄積される。このとき、図３に示すノズル５Ａを用いた場合はノズルの側方から、図４に示すノズル５Ｂを用いた場合はノズルの正面から汚れが主に吸い込まれる。このように、吸引機８により汚れを吸い取り除去することにより、油、スス、粉塵といった汚れが堆積し、閉塞した配管であっても容易に洗浄することができる。 (5) Fifth Step This step is a step of sucking the dirt with the suction machine through the flexible hollow member of the pipe cleaning tool while removing the dirt or after removing the dirt.
After the dirt is scraped off from the pipe 10 or after the dirt is scraped off, the dirt passes through the flexible hollow member 4 of the cleaning instrument A of the present invention and is sucked by the suction machine 8. In the example of FIGS. 1 and 2, the nozzle 5 located at the base of the brush 6 functions as a suction port of the suction device 8, and dirt is sucked therefrom. The sucked dirt is accumulated inside the suction machine through the flexible hollow member 4. At this time, dirt is mainly sucked from the side of the nozzle when the nozzle 5A shown in FIG. 3 is used, and from the front of the nozzle when the nozzle 5B shown in FIG. 4 is used. In this way, by sucking and removing dirt by the suction device 8, dirt such as oil, soot, and dust accumulates, and even a closed pipe can be easily cleaned.

（６）第６工程
本工程は、配管洗浄後、フレキシブル中空部材を収縮状態から伸長状態に伸ばし、当該フレキシブル中空部材で覆いながら、可撓軸や可撓性中空部材といった部品を配管から回収する工程である。本工程は、必要に応じて、上記（１）〜（５）の工程に追加される。
