BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device suitable for ejecting cleaning water mixed with a cleaning agent to remove, for example, oil stains and slime on a drain pipe.

[0002]

2. Description of the Related Art For example, a cleaning brush is provided at the tip of a long wire as a cleaning tool used when the flow of a drainage pipe becomes bad or when it starts to emit a bad odor.
There is a pipe cleaner with a handle for rotation at the rear end.

In this cleaner, the tip is inserted through the drainage hole, the brush at the tip is rotated by the handle at the rear end, and the inside of the pipe is advanced while adhering to the clogs and inner wall of the pipe such as hair, oil, dirt and scale. Use the brush on the tip to scrape off dirt or scrape it off. At this time, the scraped off or dirt is cleaned by appropriately pouring water from the drain hole and discharging it.

[0004]

However, the above-mentioned pipe cleaner has a problem that it is not possible to sufficiently remove sticky dirt and slime, such as oil, which gives off a bad smell, because of cleaning with a brush.

The pipe cleaner has a long overall length,
During use, there is slack between the brush at the front end and the handle at the rear end, so even if the wire is pushed in while turning the handle at the rear end, it is absorbed by the slack and the tip cannot be pushed forward and cannot be pushed in.

For this reason, it is difficult to move the handle forward while rotating the handle alone, and there is a problem that two workers, a person who rotates the handle and a person who pushes the handle with the wire, are required.

[0007] Therefore, an object of the present invention is to provide a cleaning tool capable of removing dirt such as oil and slime, and capable of performing the work by one person.

[0008]

In order to solve the above problems, in the present invention, a cleaning nozzle for spraying cleaning water obliquely forward is attached to the end of a flexible hose, and a connecting portion with a faucet is provided at the other end. A mixing device for mixing the cleaning agent with the cleaning water flowing in the hose is provided in the middle of the hose.

At this time, the cleaning nozzle is composed of a cylindrical case having a through hole formed from the front end face to the rear end face, and a rotary member fitted to the front end of the case and rotatably supported by a rotary shaft. In addition, a plurality of ejection holes communicating with the through hole of the case and inclined outward with respect to the through hole can be formed at the tip of the rotating member.

Further, the mixing device has a pipe line communicating with the hose, and a differential pressure device in which a small diameter passage hole is formed in the pipe line, and upstream and downstream sides of the passage hole of the differential pressure device. It is also possible to use a closed container that is connected to the conduit or the hose and contains a cleaning agent.

[0011]

In the cleaning device thus constructed, the flexible hose can be inserted into a bent drain pipe for cleaning. At this time, a jet jet in which the cleaning agent is mixed is ejected from the cleaning nozzle, and a large cleaning power can be obtained by the synergistic action of the mechanical cleaning by the pressure water and the chemical cleaning by the cleaning agent. Further, with respect to the clogging of the drainage pipe that cannot be washed out, the clogging can be eliminated by colliding the tip of the nozzle.

Further, when the washing water is supplied to the hose, the washing nozzle composed of the cylindrical case and the rotary member attached to the cylindrical case by the rotary shaft is ejected from the inclined ejection hole through the through hole of the case. The rotating member rotates due to the reaction force of the washing water. For this reason, when the hose to which the nozzle is attached is inserted into, for example, a drain pipe, the pressure water generated by the jet jet from the jet holes can be sprayed all over the inner wall to wash away the dirt in the pipe.

At this time, the pressure of the surroundings of the rotating member is lowered by the jet flow jetted obliquely forward from the jetting hole while rotating, and the suction force for sucking the nozzle in the depth direction of the drain pipe is generated. You can easily.

On the other hand, in the mixing device composed of the pressure difference device and the closed container, when the washing water passes through the passage hole formed in the pipe line of the pressure difference device, the passage hole has a small diameter, so that the passage hole has a small diameter. On the downstream side, the flow velocity is higher and the pressure is lower than on the upstream side. This pressure is applied to the cleaning agent in the closed container connected to the upstream side and the downstream side of the passage hole, respectively. For this reason,
The cleaning agent flows downstream due to the pressure difference and mixes with the cleaning water.

That is, the cleaning agent can be mixed according to the pressure difference generated in proportion to the flow rate of the cleaning water.

A cleaning nozzle 1 is attached to the tip of a flexible vinyl hose 2 (outer diameter 11 mm, inner diameter 8 mm), and a connecting portion 40 with a faucet is provided at the other end. Further, in the middle of the hose 2, a cleaning agent mixing device 20 for mixing a cleaning agent into the cleaning water flowing through the hose 2 is attached.

As shown in FIG. 2, the washing nozzle 1 is made of stainless steel and has an overall length of 9 mm and an outer diameter of 8 which is fitted into the end of the hose 2.
The cylindrical case 3 has a length of 9 mm, and the tip of the case 3 has a cylindrical rotating member 4 made of stainless steel and having a total length of 9 mm.

The rotating member 4 is composed of a head portion 5 having an outer diameter of 9 mm and a hakama portion 6 having an outer diameter of 6.5 mm, which is smaller than the head portion 5, and the inside of the hakama portion 6 is hollow with a diameter of 5.1 mm. Has become.

In this rotating member 4, the hakama 6 is fitted into a fitting hole 7 having a diameter of 6.6 mm formed in the case 3, and the rotating member 4
The case 3 is rotatably supported by a rotary shaft formed by a split pin 8 penetrating the case 3. Therefore, for example, in order to support the outer circumference of the hakama portion 6, it can be manufactured in a smaller size, lighter weight, and lower cost than a case where a bearing or the like is attached.

The fitting hole 7 of the case 3 is provided with six through holes 9 having a diameter of 1.2 mm and communicating with the rear end surface of the case 3.

On the other hand, on the end face of the head portion 5, there are formed three ejection holes 10 having a diameter of 2.4 mm and communicating with the through hole 9 through the hollow of the skirt portion 6.

The jet holes 10 are inclined 45 ° outward with respect to the through holes 9 so that the rotary member 4 is rotated by the reaction force when the pressure water is jetted from the jet holes 10. Has become.

Thus, the cleaning nozzle 1 of this embodiment
Has an inner diameter of 26 mm to 30 because the case 3 and the rotating member 4 are rotatably supported by a rotating shaft.
It can be downsized so that it can be washed by inserting it into a domestic drainage pipe of about mm.

In this embodiment, the diameter of the hakama portion 6 is smaller than that of the head portion 5. However, the present invention is not limited to this. For example, as shown in FIG.

As shown in FIG. 4, the cleaning agent mixing apparatus 20 comprises a differential pressure device 21 inserted in the middle of the hose 2 and a closed container 22 for containing a liquid cleaning agent.

The differential pressure device 21 comprises a cylindrical case 23, a partition member 24 fitted in the case 23, and a lid member 25.

As shown in FIG. 5, the lid member 25 is provided with a connection port 26 which is fitted in the hose 2 at the center of the disc, and has an internal thread formed on the inner periphery of the end of the cylindrical case 23 on the outer periphery of the disc. An external thread is formed for engagement.

The partition wall member 24 is formed by forming flanges at both ends of a cylindrical member having a through hole 27 formed therein, and the outer circumference of the flange contacts the inner circumference of the case as shown in FIG. Has become. The through hole 27 is formed to have a larger diameter than the connection port 26 of the lid member 25.

As shown in FIG. 4, the partition wall member 24 is made of O.
When sealed by the ring 28 and fixed by the lid member 25, the connection port 26 of the lid member 25 and the through hole 2 of the partition wall member 24.
With 7, the pipe line 29 communicating with the hose 2 is formed.

A passage hole 30 having a diameter smaller than the hose diameter is formed at the connecting portion between the connection port 26 and the through hole 27 of the conduit 29 due to the difference between the diameters of the two.

The passage hole 30 acts as a so-called orifice for the cleaning water flowing in the pipe 29, and causes a pressure difference so that the upstream side of the passage hole 30 has a high pressure and the downstream side has a low pressure.

On the other hand, a gap is formed by a flange between the circumference of the cylinder of the partition wall material 24 and the inner circumference of the case 23. A small hole 31 is provided between the void and the through hole 27 of the cylinder so as to communicate them.

A connection port 33 for connecting to the first connection tube 32 is provided on the outer wall of the case 23 in which the void is formed. The first tube 32 connected to the connection port 33 is connected to the closed container 22 containing a detergent.

The closed container 22 is a resin-made cylindrical container covered with a rubber cap so that airtightness can be maintained.

In this container 22, the second connecting tube 3
4 is connected, and its tube 34 is connected to the hose 2 on the downstream side of the differential pressure device 21.

Therefore, when the washing water flows, the passage hole 3
The pressure difference generated between the upstream side and the downstream side of 0 is added to the detergent in the closed container 22 by the first and second connection tubes 32 and 34, and the detergent causes the second connection tube 34 by the differential pressure. Flows into the hose 2 on the downstream side and is mixed with the wash water flowing through the hose 2.

That is, when a large amount of washing water flows through the hose 2, the flow velocity increases and the differential pressure increases, so that a large amount of detergent flows into the hose 2. Further, when the amount of washing water is small, the differential pressure becomes small and the inflow of detergent decreases.

Therefore, the diameter of the small hole 31 of the differential pressure device 21 or the diameter of the second connecting tube 34 is appropriately selected,
It is also possible to make the mixing concentration of the detergent mixed in the wash water constant by utilizing the differential pressure.

In the above embodiment, the lid members 25 are attached to both ends of the case 23 of the differential pressure device 21,
One may be formed integrally with the case 23 so that only one side can be removed.

Although the closed container 22 is a cylindrical container, it is not limited to this, and may have any shape.

Further, in the cleaning agent mixing device 20 of the present embodiment, the differential pressure device 21 and the closed container 22 are connected by the connecting tube, but the invention is not limited to this, and for example,
As shown in FIG. 6, it is possible to integrate the both into a simpler structure.

This embodiment is configured as described above, and in this cleaning device 41, liquid detergent is put in the closed container 22 and the connecting portion 40 at the rear end of the vinyl hose 2 is connected to the tap of the water supply. When tap water is passed through the faucet, the liquid detergent in the closed container 22 flows into the hose 2 and is mixed by the pressure of the wash water flowing in the hose 2.

The washing water mixed with the detergent is jetted obliquely forward from the jet holes 10 while rotating the rotating member 4 of the washing nozzle 1.

When this jetting nozzle 1 is inserted into the drain hole while holding the hose 2, the jetting pressure by the jet flow causes
Hair, dirt, etc. that have adhered to the inner wall of the drainage pipe or are clogged are blown off and washed away.

Further, highly viscous dirt and slime such as oil and water stains attached to the inner wall are also removed by the cleaning action of the detergent and the jet pressure.

Further, when it comes into contact with the block of the pipe, the tip of the nozzle 1 is collided and removed. The broken clogs are washed away by the jet.

At this time, the air pressure around the nozzle 1 is lowered by the jet flow of the nozzle 1, and a suction force works in the depth direction of the pipe, so that the pipe can be easily inserted.

As described above, in the cleaning device 41, it is possible to thoroughly remove the dirt in the drainage pipe by the ejection pressure by the ejection flow from the rotating ejection hole 10 and the cleaning power of the detergent.

Further, since the operation at that time only needs to be carried by holding the hose 2 and inserting it into the drainage hole, it can be easily performed by one person.

Although the tip of the cleaning nozzle is not covered with anything in the embodiment, the tip of the cleaning nozzle is covered with, for example, a contraction tube having a diameter larger than that of the rotating member of the cleaning nozzle so as not to damage the inner wall of the pipe. good.

Further, in the above embodiment, the cleaning device was used for cleaning the drainage pipe, but the cleaning device 41 is not limited to this, and can be used for various drainage ditch, outer floor, wall surface, automobile, and other house cleaning. Can be used in place.

[0053]

[Effect] With this configuration, the present invention makes it possible to easily clean the drainage pipe by using tap water pressure and without using other power.

Further, the pressure of the jet of the cleaning water mixed with the cleaning agent and the cleaning action of the cleaning agent can efficiently clean the drain pipe such as dirt and slime.

At this time, since the cleaning nozzle in which the rotating member is supported by the rotating shaft on the case can be downsized, it is possible to clean a small domestic drainage pipe.

Further, the cleaning nozzle can eject the jet jet while rotating the jet jet obliquely forward. For this reason, dirt and clogging of the drainage pipe can be blown off and the inside of the pipe can be thoroughly washed away.

Further, the mixing device comprising the differential pressure device and the detergent container can mix the cleaning agent by utilizing the flow rate of the cleaning water flowing through the hose. Therefore, the inflow amount of the cleaning agent can be changed according to the flow rate of the cleaning water flowing through the hose.
