Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention is directed to the r! This invention relates to a method and device for cleaning the area of A.

(Prior Art) Inside the air conditioning duct installed in a building, dust from inside the building that has passed through the filter of the air conditioner and dust from the outside air adheres and accumulates, and bacteria, mold, etc. Dust mites are breeding and becoming contaminated.

When these dust-based contaminants accumulate in the ducts and reach a certain level, they are scattered indoors through the air outlet, contaminating the indoor environment and causing serious problems in maintaining health and product quality. will give.

Generally, air conditioning ducts are located in the ceiling or inside the walls of a building.
It is arranged in a complicated manner with branch ducts. Because the space is narrow, it is difficult to approach the duct. Furthermore, since the area of the duct is small, it is difficult for people to enter and work there.

Therefore, cleaning the duct requires disassembling the ceiling panel, duct, etc., which is not easy to do.

(Problems to be Solved by the Invention) The present invention does not require any manual work such as entering the air duct or disassembling the ceiling panel or the wind pipe, and does not require the use of complicated equipment, making it simple and safe. It also ensures that the inside of the air duct is cleaned.

[Structure of the invention]

(Means for Solving the Problems) The present invention inserts a thin flexible tube into the airway, sends compressed air into the tube and blows it out from the tip, thereby making the tube move in the airway. Simply hit the tube with a tube to peel off the dust stuck to the inner wall, and insert a flexible tube into the air duct.
The purpose is to send compressed air from the outside of the lfi to knock down and remove dust in the air duct using a simple method without disassembling the ceiling panel or the air duct.

Next, the present invention comprises a thin flexible tube with a front end inserted into the ffl tract, a pressure-resistant hose connected to this flexible tube, and a compressed air supply source connected to this pressure-resistant hose. This is a simple structure consisting of a pressure tube, a pressure hose, and a compressed air supply source such as a compressor, which reduces the number of components and simplifies operation.

(Function) In the present invention, compressed air is ejected from a thin flexible tube, and the ejected force causes the flexible tube to move and strike the inner wall of the airway, thereby peeling off the dust that has adhered to the inner wall of the airway. .

Next, in the present invention, a thin flexible tube with an open end is inserted into the airway, and compressed air is supplied to this tube from a compressed air supply source, so that the tube moves and hits the inner wall of the airway.

(Example) An embodiment of the invention will be described with reference to FIG.

Reference numeral 1 denotes a wind passage, one end of which is connected to an air conditioner (not shown), the middle of which is disposed substantially horizontally in the ceiling 2, etc., and the other end of which has an air outlet 3 open into the room 4. Furthermore, a duct of a vacuum dust collector 5 is connected to the air outlet 3 by a connector 7.

8 is a pressure-resistant hose, one end of which is connected to the compressor 9;
The connector 7 is inserted into the air passage 1 through an insertion port 10.

A coiled flexible wire 11 is placed along the entire length of the pressure hose 8, and both are tied together by connecting pieces 12 at appropriate intervals.

Reference numeral 13 is a flexible duplex made of, for example, rubber, which has an air outlet 14 at its tip and whose base end is connected to the tip of the pressure hose 8 by a connecting fitting (not shown). That is, the tip of a ventilated connecting fitting attached to the tip of the pressure-resistant bow 8 is inserted into the base end of the flexible tube 136 and fixed with adhesive. The flexible tube 13 is appropriately selected depending on the diameter, shape, etc. of the air passage 1, but generally has an inner diameter of 3s to 5s,
2 shoes thick, length 10cm to 50cIR (preferably 30cm
cm) and has a length sufficient to contact the inner wall of the air duct 1.

Next, a cleaning method using the S position of this embodiment will be explained.

A pressure-resistant hose 8 with a flexible duplex 13 connected to its tip is inserted into the air passage 1 through the insertion port 10 of the connector 7 together with the flexible wire 11. At this time, the pressure hose 8 is guided by the flexible wire 11 and inserted into the air passage 1 to an arbitrary position. Next, when the compressor 9 is operated to send compressed air into the pressure hose 8, the compressed air is ejected from the air ejection port 14 at the tip of the flexible tube 13. The flexible tube 13 at the tip moves vigorously within the air duct 1 due to the air jet force, and the flexible duplex 13 strikes the inner wall surface of the air duct 1. Then, the dust stuck inside the air duct 1 is peeled off.

In order to effectively operate the flexible tube 13, the air pressure at the outlet of the compressor 9 must be greater than 4 Kg/cti.

After the dust in the air passage 1 is removed as described above, the vacuum blood collector 5 is activated to suck and remove the dust separated in the air passage 1.

Next, FIG. 2 shows another embodiment.

In this embodiment, a brush-like flexible support member 15 is formed around the tip of the flexible wire 11. The supporting member 15 has a tip end inscribed in the airway 1 so that the flexible wire 11 is located at the center of the diameter of the airway 1.

According to this embodiment, since the tip of the flexible wire 11 is always installed at the center of the airway 1, the base of the flexible duplex 13 is located at the center of the airway 1, and therefore the diameter of the airway 1 is Flexibility even in large cases 13
Hammer the inner wall of the wind path 1 with a full force. When the flexible wire 11 is inserted or removed from the insertion port 10 along with the pressure hose 8, the support member 15 is attached to the flexible wire 11.
ni;a bends so that it does not become 5mm.

The rest of the structure and operation are the same as those of the previous embodiment.

〔Effect of the invention〕

The present invention inserts a thin flexible duplex into the Jul.
By sending B compressed air into this tube and ejecting it from the tip, the duup is made to move in the wind duct, and the inner wall of the wind duct is struck by the duup to peel off the dust that has rained on the inner wall. The air duct can be easily cleaned by simply inserting a flexible tube into the air duct, without requiring extensive work such as peeling off the ceiling or disassembling the air duct.

Next, the present invention is flexible because it consists of a thin flexible tube with an open end that is inserted into the air duct, a pressure-resistant hose connected to this flexible duplex, and a compressed air supply source connected to this pressure-resistant hose. By simply connecting the tube and the pressure-resistant hose to a compressed air supply source such as a conbrella, there is no need for a complicated mechanism or large equipment, and the device is simple and requires a small number of parts, making maintenance management easy.
