Description

【考案の詳細な説明】（産業上の利用分野）本考案は主として空気調和装置のダクト内を清
掃する装置に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to an apparatus for cleaning the inside of a duct of an air conditioner.

を一般とする。(Prior Art) Conventionally, the inside of a duct of an air conditioner is generally cleaned by inserting an air hose into the duct and blowing out dust and the like inside to a collection port using air jet power.

（考案が解決しようとする問題点）しかしながら、上記従来法によれば、埃等に若

くなり、収集不能となる不都合があつた。(Problem to be solved by the invention) However, according to the above-mentioned conventional method, if the dust is slightly sticky, for example, if the dust is mixed with cigarette grease, the dust will stick to the inner surface of the duct. There was an inconvenience that the particles adhered to each other, and the adhesion force overcame the jetting force of the air, preventing them from flying, making it impossible to collect them.

を突設させたことを特徴とする。(Means for Solving the Problem) The present invention attempts to solve the above-mentioned inconvenience by adding a means to remove dust, etc. from the inner surface of the duct to the conventional device. A cylindrical holder is connected to the distal end of the holder at an opening at one end thereof, and a flexible finned tube communicating with the inside of the holder is provided protruding from a closed portion at the other end of the holder.

収集口まで吹き飛ばされる。(Function) The present invention has the above-mentioned configuration. According to this, dust etc. adhering to the inner surface of the duct are knocked away from the inner surface of the duct by being hit by the finned thin tube which itself flutters and sways due to the air jet force. The air is then blown away to the collection port by the air jet force from this finned tube.

（実施例）次に本考案の実施例を図示のものにつき説明す
る。(Example) Next, an example of the present invention will be described with reference to the drawings.

図面で１はウレタン製耐圧用のエアーホース、

ント金具により連結される。 In the drawing, 1 is a pressure-resistant air hose made of urethane,
Reference numeral 2 indicates a cylindrical holder made of vinyl having one end open and the other end closed, and the tip of the air hose 1 and the open end of the holder 2 are connected by a joint fitting (not shown).

められる。 To do this, insert the air hose 1 having the finned tube 6 into the duct 5 of the air conditioner and feed compressed air of, for example, 7 kg/cm ² into the air hose 1. Air is blown out while the inner surface of the duct 5 is struck, and dust and the like inside the duct 5 are efficiently collected in the collection port 7.

する。(Effect of the invention) As described above, according to the invention, a flexible finned tube is provided at the tip of the air hose to communicate with the air hose, and the finned tube blows air into the duct and hits the inner surface of the duct. Since the inside of the duct is cleaned by using air jets, it is possible to remove dust and the like inside the duct much more efficiently than the conventional method which cleans the inside of the duct using only air jet force.
