Description

[Detailed description of the invention] The present invention relates to an apparatus for cleaning the inside of an empty HIM duct.

With the increase in the number of high-rise buildings, the demand for indoor air conditioning is also increasing, and the total length of air conditioning ducts is also rapidly increasing.

As the air conditioner duct 1- is used for many years, dust, lint, carbon, etc. accumulate in the duct, and bacteria and bacteria grow. 1, air pollution and Doug 1 ~ fire,
Cases of disease outbreaks of the tracheal system have been reported.

These safety and health problems have been increasingly pointed out for some time, and in order to prevent them, regular cleaning of these ducts has been called for as a new urban disaster problem.

However, ducts are often installed in heavy-duty equipment, making it difficult for workers to perform the work due to inconvenient or unnatural postures, and requiring time and effort to clean. Because of this, the reality is that duct cleaning is not easy.

The present invention has been made with attention to the above points, and it is an object of the present invention to provide a second device that effectively performs cleaning inside a duct.

An embodiment of the present invention will be described below.

In FIG. 1, a pair of air hacks 2 are arranged at appropriate intervals inside an air conditioning duct 1-1. The air hack 2 is formed by forming a flexible sheet such as rubber, soft synthetic resin, or fiber into a bag shape. It is possible to seal the passageway i and make it a cutoff field.Then, work is carried out for each blocked closed space R.

Sleeves 5 and 6 are inserted when blocking the air hack 2 passage. An IJ1 trachea 8 is inserted through one sleeve 5, and a 1 NOF air fan 8' is connected to the exhaust pipe 8. An air supply pipe 7 and a flexible rotating shaft 19 (described later) are inserted into the other sleeve 6, and the air supply pipe 7
An air supply fan 7' is connected to the air supply fan 7'.

A rotary duster 16 is movably arranged in the closed section R. As shown in FIG.
Supported by

1. The leg opening device 11 has one end attached to the outer periphery of the bearing side 12.
It is constituted by a plurality of diagonal supporting parts 13.

When the support part 13 is locked, the support part 12 is locked by a rotatable shaft support means so that the support part 12 can freely open in an umbrella shape from the bearing member 12, and the support part 13 is locked around the bearing member 120. Multiple pieces are arranged in the radial direction.

A spring 14 is provided between the support part 13 and the bearing member 12, and several wheels 15 are rotatably cut out at the other end of the support part 13.

As shown in FIG. 3, the support portion 13, which is disposed in the direction of the radial force and with its legs spread, generally has a rectangular shape of 1υ? N legs are spread out on the inner surface of the duct 1, and the bottom surface 1a,
Press the wheels on the ceiling IC and both sides 11] and 1d.
, the bearing portion 4; 112 is maintained at the center of the cross section of the deck 1. A suitable plurality of support parts 13, for example 4 to 8 support parts, are provided. The wheels 15 are in contact with the inner surface of the duct ■, respectively, and the bearing portions 4A1
It facilitates the forward and backward movement of 2'JiJ+.

-1- A piece of silk 18 is attached to the rotating shaft 17, which is rotatably supported by the bearing JtA12, with one end fixed thereto.

k711B has a sufficient length to reach the inner wall surface of the duct, and stamps the inner wall surface of the duct. 1vli8 is t+t
I-fiber threads, ribbons, tapes, etc. (used).

In addition to the rotary shaft 17, the shaft t+41 is connected to the rotary shaft 19 (9). The rotating shaft 19 passes through the sleeve 6,
The outside of the duct is appropriately extended by −1 and conducted by the ivy 0.

In the above embodiment, the duster 16 is
The duct is rotated and stamped on the duct surface to knock off accumulated dirt, float, and move inside the duct for cleaning. The air is exhausted through an exhaust pipe 8 by an exhaust fan 8'.

In the practical example of FIG. 4, a double pipe system 26 is arranged in the duct closed section R. The device is supported by the same device as the leg splitting device in the previous embodiment L).

In the double pipe 26, an inlet 28 is provided on the end surface of the inner pipe 27, and an outer pipe 29 with an air passage provided outside the inner pipe 27 is provided. An air jet 20 is provided in the section with an opening in the !1 and 1 directions.

The double pipe 26 is disposed to pass through the center of one airbag 2, and the intake pipe 22 is connected to the outer pipe 29, and the exhaust pipe 21 is connected to the inner pipe 27. Supply, exhaust pipe 2I
, 22 are connected to a fan 23 to form circulation piping. As another example, the air hack 2 may not be passed through the double pipe 26, but the suction and trachea 21, 22 may be led out from the duct 1a of the duct 1.

The rotary shaft 19 is supported by a support member 30 relative to the center of the double pipe 26 and protrudes from the suction hole 28.

Therefore, in this case, from the double pipe 26 to the support part side 3
0 serves as the bearing portion side of the flexible rotating shaft 19. The protruding end RB 19a of the flexible rotating shaft 19 has a puff-type peeler 16'.
is provided. On the other hand, during use, the flycatcher 1G' moves along the inner surface of the duct 1 without rotating.

In the embodiment of FIG. 5, the double pipe 26' is a parallel double pipe and is composed of an inner pipe 27' and an outer pipe 29'.
28' is provided on the end surface of the inner tube 27', and an inner tube 28' is provided at the end of the outer tube 29'. A number of air jets 20' are provided surrounding the TLL pipe 27'.

In the practical example shown in FIG. 6, the flexible rotating shaft 19 in the embodiment shown in FIG.
It is provided.

As mentioned above, the floating power is
It can be effectively evacuated via an exhaust device.

As described above, according to the present invention, a rotating duster produced at a high speed via a flexible rotating shaft is inserted into a duct.
By operating iJ f multi-movement-U, 1 (1)
It can be removed by shaking off the buildup and letting it float. Therefore, the cleaning can be performed hygienically, safely, and reliably without the need for workers to sneak into the duct.
