Then, a suction hole that rotates together with the brush is provided in the rotating body so that dust peeled from the inner wall of the duct is sucked into the suction hose from this suction hole.

特開2001−280333号公報Japanese Unexamined Patent Publication No. 2001-280333 特開2009−131791号公報Japanese Unexamined Patent Publication No. 2009-131791

しかし、特許文献2のダクト清掃器具では、吸引ホースと内部のフレキシブルシャフトの太さが全長にわたって均一であるため、曲がり易さも全長に亘って均一であり、ダクトのコーナーを曲がる際に、曲がってほしい吸引ホースの先端が曲がらず、中間部分が曲がってしまって、ダクトがコーナーの奥に入りにくく、長くてコーナーの多い排気ダクトは清掃しにくいという問題が有る。
本発明は、上記課題に鑑みてなされたものであり、ダクトのコーナーの奥へ回転体を設けた先端を入れることが容易で、長くてコーナーの多い排気ダクトであっても清掃しやすいダクト清掃器具、及びこれを用いたダクト清掃方法の提供を目的とする。
However, in the duct cleaning tool of Patent Document 2, since the thickness of the suction hose and the flexible shaft inside is uniform over the entire length, the ease of bending is also uniform over the entire length, and when the corner of the duct is bent, it bends. There is a problem that the tip of the desired suction hose does not bend, the middle part bends, the duct is difficult to enter the back of the corner, and the long exhaust duct with many corners is difficult to clean.
The present invention has been made in view of the above problems, and it is easy to insert the tip provided with a rotating body into the back of the corner of the duct, and it is easy to clean even an exhaust duct having many long corners. An object of the present invention is to provide an instrument and a duct cleaning method using the instrument.

上記課題を解決するためになされた発明は、ダクトの内部を清掃するダクト清掃器具であって、回転駆動装置に連結されて回転駆動されるフレキシブルシャフトと、前記フレキシブルシャフトの先端に着脱自在に連結される回転ブラシ、又は回転バフからなる回転清掃具とを備え、前記フレキシブルシャフトは、基端が回転駆動装置に着脱自在に連結されるメインシャフトと、前記メインシャフトより短尺に設けられ、基端が前記メインシャフトの先端に着脱自在に連結されるサブシャフトとを有し、前記メインシャフト、及びサブシャフトは、金属線をらせん状に巻回した芯線を可撓性樹脂により被覆してなる索条部を有し、前記サブシャフトの索条部は、前記メインシャフトの索条部より全径が細い。 The invention made to solve the above problems is a duct cleaning tool for cleaning the inside of a duct, which is detachably connected to a flexible shaft that is connected to a rotary drive device and is rotationally driven and is detachably connected to the tip of the flexible shaft. The flexible shaft is provided with a main shaft whose base end is detachably connected to a rotary drive device, and a rotary cleaning tool made of a rotary brush or a rotary buff, which is shorter than the main shaft. Has a sub-shaft that is detachably connected to the tip of the main shaft, and the main shaft and the sub-shaft are cords formed by coating a core wire in which a metal wire is spirally wound with a flexible resin. has ridges, rope portion of the sub-shaft, the overall diameter is not fine than rope portion of the main shaft.

このように、フレキシブルシャフトの先端側のサブシャフトの全径を、同基端側のメインシャフトの全径より細くしたので、サブシャフトがメインシャフトより曲がりやすく、ダクトに入れたフレキシブルシャフトを、メインシャフト側から押した場合に、基端側のメインシャフトが折れ曲がる前に先端側のサブシャフトが折れ曲がるので、ダクト清掃器具が、ダクトのコーナーに沿って曲がりやすい。 In this way, the total diameter of the sub shaft on the tip side of the flexible shaft is made smaller than the total diameter of the main shaft on the base end side, so the sub shaft is easier to bend than the main shaft, and the flexible shaft put in the duct is used as the main. When pushed from the shaft side, the sub-shaft on the tip side bends before the main shaft on the base end side bends, so that the duct cleaning device easily bends along the corner of the duct.

そして、本発明は、サブシャフトの索条部が前記メインシャフトの索条部より芯線の径が太いを特徴とする。こうすることで、繰り返し折れ曲がることによるサブシャフトの損傷を抑制することができる。 The present invention is characterized in that the cord portion of the sub-shaft has a larger core wire diameter than the cord portion of the main shaft. By doing so, it is possible to suppress damage to the sub-shaft due to repeated bending.

本発明は、上記のダクト清掃器具と、ダクト内の塵埃を吸引する集塵機の吸引ホースをダクトの排気口に連結する集塵ノズルとを備え、前記集塵ノズルは、前記メインシャフトを挿通可能な挿入口と、前記メインシャフトを挿通可能に構成されるとともにダクトの排気口に連結される送出口と、集塵機に連結される排気口とを備えるダクト清掃キットを含む。このような、集塵機を用いることで、回転清掃具でダクト内壁の塵埃を掃き落としながら、同時にダクトの排気口から塵埃を吸引することができる。 The present invention includes the above-mentioned duct cleaning device and a dust collecting nozzle for connecting a suction hose of a dust collector for sucking dust in the duct to an exhaust port of the duct, and the dust collecting nozzle can insert the main shaft. Includes a duct cleaning kit including an insertion port, an inlet that is configured to allow the main shaft to be inserted and is connected to an exhaust port of the duct, and an exhaust port that is connected to a dust collector. By using such a dust collector, it is possible to sweep off the dust on the inner wall of the duct with a rotary cleaning tool and at the same time suck the dust from the exhaust port of the duct.

本発明は、本発明に係るダクト清掃器具を用いてダクトの清掃を行うダクト清掃方法を含む。特に、本発明のダクト清掃方法は、前記ダクトが、トイレ、洗面所、風呂場等の被排気室の吸引口と換気扇を結ぶ一又は複数の上流側の部分排気ダクトと、前記換気扇と屋外へ空気を排気する排気口とを結ぶ下流側の部分排気ダクトとを有する排気ダクトの清掃に用いることが好ましい。かかる排気ダクトに、本発明に係るダクト清掃器具を用いることで、より綺麗に掃除を行うことができる。 The present invention includes a duct cleaning method for cleaning a duct using the duct cleaning tool according to the present invention. In particular, in the duct cleaning method of the present invention, the duct connects one or a plurality of upstream partial exhaust ducts connecting a suction port of an exhaust room such as a toilet, a washroom, or a bathroom with a ventilation fan, and the ventilation fan and the outside. it is preferably used to clean the exhaust duct having a downstream parts partial exhaust duct connecting the exhaust port for exhausting air. By using the duct cleaning tool according to the present invention for such an exhaust duct, cleaning can be performed more beautifully.

本発明に係るダクト清掃方法は、換気扇を前記排気ダクトから取り外したのち、前記いずれかの部分排気ダクトの上流側と下流側の一側から前記ダクト清掃器具を挿入して当該部分排気ダクトを清掃したのち、当該部分排気ダクトの上流側と下流側の他側から前記ダクト清掃器具を挿入して前記部分排気ダクトを清掃することが好ましい。
本発明のダクト清掃器具は、フレキシブルシャフトの先端が曲がりやすいため、下流側排気ダクトの排気口からだけでなく、天井裏に有ってフレキシブルシャフトの差し込みにくい、部分排気ダクトの換気扇から取り外した端部からでも、フレキシブルシャフトを差し込むことができる。これにより、部分排気ダクトを上下流の両側から清掃することができ、上流側から、又は下流側からのみでは、回転清掃具の当たらない箇所にも回転清掃具を当てることができるため、部分排気ダクトを、より綺麗に清掃することができる。
In the duct cleaning method according to the present invention, after removing the ventilation fan from the exhaust duct, the duct cleaning device is inserted from one of the upstream side and the downstream side of the partial exhaust duct to clean the partial exhaust duct. After that, it is preferable to insert the duct cleaning device from the other side of the upstream side and the downstream side of the partial exhaust duct to clean the partial exhaust duct.
In the duct cleaning tool of the present invention, since the tip of the flexible shaft is easily bent, the end removed from the ventilation fan of the partial exhaust duct, which is located behind the ceiling and difficult to insert the flexible shaft, as well as from the exhaust port of the downstream exhaust duct. The flexible shaft can be inserted even from the part. As a result, the partial exhaust duct can be cleaned from both the upstream and downstream sides, and the rotary cleaning tool can be applied to a place where the rotary cleaning tool does not hit only from the upstream side or the downstream side. The duct can be cleaned more cleanly.

本発明は、換気扇を前記排気ダクトから取り外したのち、前記いずれかの上流側の部分排気ダクトと前記下流側の部分排気ダクトを連結した状態で、前記ダクト清掃器具を前記排気ダクトに挿入して前記排気ダクトを清掃するダクト清掃方法を含む。
本発明のダクト清掃器具は、フレキシブルシャフトの先端が曲がりやすいため、長くてコーナーの多い排気ダクトであっても、フレキシブルシャフトを奥の方まで差し入れることができる。従って、上流側の部分排気ダクトと下流側の部分排気ダクトを連結して全長が長く、コーナーが多くなった状態でも十分に清掃を行うことができる。そして、このように、上流側と下流側の部分排気ダクトを連結することで、上流側の部分排気ダクトの内部を下流側の部分排気ダクトの排気口に連結した集塵機により吸引を行いながら清掃することができる。
In the present invention, after the ventilation fan is removed from the exhaust duct, the duct cleaning device is inserted into the exhaust duct with the partial exhaust duct on the upstream side and the partial exhaust duct on the downstream side connected to each other. The duct cleaning method for cleaning the exhaust duct is included.
In the duct cleaning tool of the present invention, since the tip of the flexible shaft is easily bent, the flexible shaft can be inserted all the way into the exhaust duct even if it is long and has many corners. Therefore, the partial exhaust duct on the upstream side and the partial exhaust duct on the downstream side are connected to have a long overall length, and sufficient cleaning can be performed even when there are many corners. Then, by connecting the upstream side and the downstream partial exhaust ducts in this way, the inside of the upstream partial exhaust duct is cleaned while being sucked by the dust collector connected to the exhaust port of the downstream partial exhaust duct. be able to.

さらに、本発明に係るダクト清掃方法は、前記排気ダクトを前記ダクト清掃器具で清掃したのち、前記排気口に集塵ネット取付パーツを取り付け、前記排気ダクトの上流側から、ブロアーにより空気を流送して、前記排気ダクトを清掃することが好ましい。本発明のダクト清掃装置によれば、長くてコーナーの多い排気ダクトでも清掃することができるようになるが、かかる排気ダクトでは、下流側から集塵機で吸引するだけでは、払い落とした塵埃を十分に回収できない虞がある。排気ダクトの上流側から、ブロアーにより空気を流送することで、より確実に払い落とした塵埃を除去することができる。 Further, in the duct cleaning method according to the present invention, after cleaning the exhaust duct with the duct cleaning device, a dust collecting net attachment part is attached to the exhaust port, and air is flowed from the upstream side of the exhaust duct by a blower. Then, it is preferable to clean the exhaust duct. According to the duct cleaning device of the present invention, even an exhaust duct that is long and has many corners can be cleaned. However, in such an exhaust duct, the dust that has been wiped off can be sufficiently removed by simply sucking the dust from the downstream side with a dust collector. There is a risk that it cannot be collected. By blowing air from the upstream side of the exhaust duct with a blower, the dust that has been wiped off can be removed more reliably.

本発明のダクト清掃器具、及びダクト清掃方法によれば、長くてコーナーの多い排気ダクトの奥まで容易に回転清掃具を挿入して、十分に清掃を行うことができる。 According to the duct cleaning tool and the duct cleaning method of the present invention, the rotary cleaning tool can be easily inserted into the depth of the exhaust duct which is long and has many corners, and sufficient cleaning can be performed.
