Description

The present invention relates to a pipe clogging remover for removing clogging of a pipe such as an air conditioner or a drain pipe for draining drain water from a freezer.

The air conditioner or the like has a drain pipe 2 for discharging the drain water mixed with dust taken from the atmosphere, lubricating oil in the compressor, metal powder, etc. to the outside. As described above, the drain pipe 2 may be mixed with dust, lubricating oil, metal powder, etc., and therefore, the pipe may be clogged with foreign matter in which these dust, lubricating oil, metal powder, etc. are solidified due to long-term use.

As an instrument for removing clogging of a pipe such as the drain pipe 2, for example, Non-Patent Document 1 describes a suction pump 100 for a drain hose. The conventional suction pump 100 is shown in FIG. The suction pump 100 has an outer cylinder portion 101 formed in a tubular shape having a tapered tip 104, a gasket 102 that slides inside the outer cylinder portion 101, and one end fixed to the gasket 102. An elongated operation portion 103 extending to the other end side of the outer cylinder portion 101 is provided.

In the step of clearing the clogging of the drain pipe 2, first, the tapered tip 104 of the outer cylinder portion 101 is connected to the outdoor end of the drain pipe 2, and the operation portion 103 is pushed and pulled to push and pull the gasket 102 to the outer cylinder. The gasket 102 is reciprocated in the axial direction inside the portion 101. When the gasket 102 moves in the direction approaching the tip 104 of the outer cylinder portion 101, air is discharged from the outer cylinder portion 101 into the drain pipe 2, and when the gasket 102 moves in the direction away from the tip 104 of the outer cylinder portion 101, it is outside. Since the air in the drain pipe 2 is sucked from the tip of the tubular portion 101, the drain pipe 2 is repeatedly pressurized and depressurized from the end on the outdoor side, and the foreign matter clogged in the drain pipe 2 is removed from the drain pipe 2. It is peeled off from the inner circumference of the drain pipe 2 and swept away by the drain water to the outdoor end of the drain pipe 2.

By the way, since it is necessary for the drain pipe 2 to flow down the drain water, it often extends in the vertical direction, and the end portion of the drain pipe 2 on the outdoor side is often opened downward. In addition, since drain water containing foreign matter is discharged, it is preferable that an opening is provided at a low position, and the outdoor end of the drain pipe 2 is located near the ground, dirt floor, balcony floor, or the like. Often located in.

On the other hand, as shown in FIG. 9, the tip of the conventional suction pump 100 is open in the axial direction of the outer cylinder portion 101, and as described above, the drain pipe is near the ground, the soil floor, the floor of the balcony, or the like. Since the outdoor end of 2 is open, when the tip of the suction pump 100 is connected to the outdoor end of the drain pipe 2, these grounds, dirt floors, balconies, etc. are in the way of the suction pump. It is difficult to arrange 100 in the vertical direction. Therefore, it is necessary to bend and connect the outdoor end of the drain pipe 2 so that it can be connected to the tip of the suction pump 100.

However, the drain pipe 2 is fixed to the outer wall of a building, for example, and it may be difficult to bend the end portion thereof. Further, since the suction pump 100 must be operated while holding the end portion of the drain pipe 2 in a bent state, there is a problem that the work becomes difficult.

Therefore, in the present invention, even when the end of the drain pipe is open downward and the end of the drain pipe is close to the ground or the like, the end of the drain pipe can be easily bent without bending. It is an object of the present invention to provide a pipe clogging removing tool capable of removing foreign matter stuck in a drain pipe.

The first tube clogging clearing tool of the present invention is provided at the outer cylinder portion formed in a tubular shape, the tapered portion formed at one end of the outer cylinder portion, and the tip of the tapered portion. A tip portion formed in a tubular shape having a diameter smaller than that of the outer cylinder portion, a gasket that slides inside the outer cylinder portion, and an elongated portion that is fixed to the gasket at one end and extends to the other end of the outer cylinder portion. A pipe clogging remover that includes an operation unit and removes foreign matter stuck inside the drain pipe for discharging the drain water of the air conditioner to the outside, and the tip portion is attached to and detached from the tapered portion. The tip portion is freely joined, and one end side connected to the tapered portion extends in the axial direction of the outer cylinder portion and is bent at the intermediate portion, and the other end is in the axial direction of the outer cylinder portion. Is characterized in that it is possible to change between an attachment that opens in different directions and an attachment that does not bend .

The second tube clogging clearing tool of the present invention is characterized in that, in addition to the characteristics of the first tube clogging clearing tool, the tip portion is bent at least 90 degrees or more at the intermediate portion.

According to the first tube clogging remover, one end of the tip that connects to the tapered portion extends in the axial direction of the outer cylinder and bends in the middle, and the other end is in the axial direction of the outer cylinder. Since it opens in different directions, even if the outdoor end of the drain pipe is located close to the ground, dirt floor, balcony floor, etc. and is arranged so that it opens downward, the outer cylinder is almost open. The tip can be opened upward while being held horizontally, and foreign matter stuck in the drain pipe can be easily removed without bending the end of the drain pipe.

According to the second tube clogging remover, the tip is bent at least 90 degrees in the middle, so at least the outer cylinder is tilted and held so that the tip goes down so that the tip faces upward. It is possible to open the drain pipe and easily remove the foreign matter stuck in the drain pipe without bending the end portion of the drain pipe.

According to the first tube clogging eliminator, since the tip is detachably joined to the tapered portion, the tip can be used as an attachment, for example, depending on the shape of the end of the tube filled with foreign matter. The tip shape can be changed.

Hereinafter, the best embodiment of the tube clogging clearing tool 1 according to the present invention will be described with reference to each figure. The pipe clogging clearing tool 1 removes foreign matter stuck inside the drain pipe 2 for discharging the drain water of the air conditioner to the outside, for example. The drain pipe 2 is a flexible pipe made of resin, and the heat insulating tube 3 is extrapolated. The pipe clogging remover 1 of the present invention is not limited to the one that removes the foreign matter stuck in the drain pipe 2, and can be used, for example, when removing the foreign matter stuck in the drain pipe.

As shown in FIGS. 1 and 2, the tube clogging clearing tool 1 includes an outer cylinder portion 4 formed in a tubular shape, a tapered portion 5 formed at one end of the outer cylinder portion 4, and a tapered portion. A gasket that slides inside the outer cylinder portion 4, the tip portion 6 provided at the tip of the fifth, the rear end portion 7 formed so as to cover the other end of the outer cylinder portion 4 and the insertion hole 71 formed in the center, and the inside of the outer cylinder portion 4. 8 and an elongated operation portion 9 having one end fixed to the gasket 8 and extending in the direction of the other end of the outer cylinder portion 4 are provided.

The outer cylinder portion 4 is a resin cylinder. The tapered portion 5 has a tubular fixed portion 51 that is externally attached to one end of the outer tubular portion 4 and airtightly adhered, a truncated cone portion 52 that reduces the diameter from the fixed portion 51 toward the tip, and a truncated cone portion 52. It has a male screw portion 53 provided at the tip provided at the tip of the above, and the inside is a cavity in which the fixed portion 51 and the end portion of the male screw portion 53 are open.

The tip portion 6 is made of resin and has a female screw portion 61 screwed to the male screw portion 53 of the taper portion 5, a base end portion 62 extending from the female screw portion 61 in the axial direction of the outer cylinder portion 4, and a base end portion. A connecting portion 63 that bends and extends from 62 is integrally formed. The bending angle of the tip portion 6 is preferably at least 90 degrees or more. The bending angle of the tip portion 6 in the present embodiment is 100 degrees. The connecting portion 63 is provided with a step 64 in the middle to shorten the diameter on the tip side. The most tip side of the connecting portion 63 has a diameter of 14 mm, and the base end portion 62 side of the step 64 has a diameter of 16 mm, so that it can be connected to the drain pipes 2 having inner diameters of 14 mm and 16 mm.

Since the female screw portion 61 of the tip portion 6 is screwed to the male screw portion 53 of the taper portion 5, it can be easily removed by turning the tip portion 6 in the loosening direction with respect to the taper portion 5. Further, the tip portion 6 can be easily screwed by turning the tip portion 6 in the tightening direction with respect to the tapered portion 5. For example, by preparing an attachment that does not bend at the tip portion or an attachment that matches the shape of the pipe other than the drain pipe 2, foreign matter stuck in the pipe other than the drain pipe 2 can be removed.

As shown in FIGS. 2 and 3, the rear end portion 7 covers the tubular adhesive portion 72 that is externally attached to the other end of the outer cylinder portion 4 and airtightly adhered, and the other end of the outer cylinder portion 4. It has a cover portion 73, an insertion hole 71 provided in the center of the cover portion 73, and an intake / exhaust port 74 for sucking and exhausting outside air from the other end of the outer cylinder portion 4 into the outer cylinder. The gasket 8 has a cylindrical shape that airtightly contacts the inner circumference of the outer cylinder portion 4, is made of an elastomer, and is formed so as to be slidable in the axial direction of the outer cylinder portion 4. An operation portion 9 elongated in the axial direction of the outer cylinder portion 4 is fixed to the gasket 8 toward the rear end portion 7 side. The operation unit 9 has a thin cylindrical push rod 91 whose one end is fixed to the gasket 8 and inserted into the insertion hole 71 of the cover portion 73, and a grip hole formed at the other end of the push rod 91 for the operator to grip. It has a grip portion 93 on which 92 is formed.

As shown in FIG. 2, with the operation unit 9 pushed into the outer cylinder portion 4, as shown in FIG. 3, the grip portion 93 is gripped and the operation portion 9 is pulled out from the outer cylinder portion 4. Then, inside the outer cylinder portion 4, the gasket 8 slides from one end side to the other end side of the outer cylinder portion 4. Then, as the gasket 8 slides, the space on one end side of the outer cylinder portion 4 expands with the gasket 8 as a boundary, and the space on the other end side of the outer cylinder portion 4 narrows. Therefore, the air pressure in the space on one end side of the outer cylinder portion 4 drops, and the outside air is taken in from the opening of the tip portion 6 communicating with the space. On the other hand, the air pressure in the space on the other end side of the outer cylinder portion 4 rises, and air is discharged to the outside from the suction / exhaust port 74 of the rear end portion 7 communicating with the space.

Then, as shown in FIG. 3, in a state where the operation unit 9 is pulled out from the outer cylinder portion 4, as shown in FIG. 2, the grip portion 93 is gripped and the operation portion 9 is pushed in the direction of pushing into the outer cylinder. Then, inside the outer cylinder portion 4, the gasket 8 slides from the other end side of the outer cylinder portion 4 toward one end side. Then, as the gasket 8 slides, the space on one end side of the outer cylinder portion 4 narrows with the gasket 8 as a boundary, and the space on the other end side of the outer cylinder portion 4 expands. Therefore, the air pressure in the space on one end side of the outer cylinder portion 4 rises, and air is discharged to the outside through the opening of the tip portion 6 communicating with the space. On the other hand, the air pressure in the space on the other end side of the outer cylinder portion 4 drops, and the outside air is sucked in from the suction / exhaust port 74 of the rear end portion 7 communicating with the space.

When the drain pipe 2 is clogged with foreign matter, first, as shown in FIG. 4, the connecting portion 63 of the tip portion 6 is inserted into the drain pipe 2 to connect the drain pipe 2 and the tip portion 6. Then, the grip portion 93 of the operation portion 9 is gripped, the operation portion 9 is pushed and pulled as shown in FIG. 4, and the operation portion 9 is pushed into the outer cylinder portion 4 as shown in FIG. As shown in FIG. 5, the state in which the operation unit 9 is pulled out from the outer cylinder portion 4 is repeated. As a result, intake and exhaust are repeated from the opening of the tip portion 6, and pressurization and depressurization are repeated from the end on the outdoor side inside the drain pipe 2, and foreign matter clogged in the drain pipe 2 is removed from the drain pipe 2. It is peeled off from the inner peripheral surface of the drain pipe 2 and swept away by the drain water to the outdoor end of the drain pipe 2.

As described above, the pipe clogging clearing tool 1 of the present embodiment is arranged so that the outdoor end of the drain pipe 2 opens downward at a position close to the ground, the soil floor, the floor of the balcony, or the like. Even if there is, the tip portion 6 can be opened upward while the outer cylinder portion 4 is held substantially horizontally, and it is easy without bending the end portion of the drain pipe 2 without the ground or the like getting in the way. Foreign matter stuck in the drain pipe 2 can be removed.

In the above-described embodiment, the tip portion 6 of the tube clogging clearing tool 1 is bent from the female screw portion 61, the base end portion 62 extending from the female screw portion 61 in the axial direction of the outer cylinder portion 4, and the base end portion 62. The connecting portion 63 extending through the shaft is integrally formed, and is always bent at the intermediate portion, but the present invention is not limited to this. Next, a modified example of the embodiment of the tube clogging clearing tool 1 will be described.

As shown in FIGS. 6 and 7, the tip portion 6 of the modified example is configured to be swingably bent at the intermediate portion. Specifically, for example, as shown in FIG. 7, the joint portion between the base end portion 62 and the connection portion 63 of the tip portion 6 is formed in a ring shape, and one is extrapolated and extrapolated to the other so as to be swingable. An air flow path is provided so that the end portion 62 and the connecting portion 63 communicate with each other.

With this configuration, the opening direction of the tip 6 can be changed regardless of the posture of the outer cylinder 4, and what is the orientation of the outdoor end of the drain pipe 2 and the shape of the installation location? Even in this case, the tip portion 6 can be easily connected to the end portion of the drain pipe 2.

Further, in another modified example, as shown in FIG. 8, the tip portion 6 has a flexible bellows tube 65 formed in the intermediate portion. That is, there is flexibility between the base end portion 62 and the connecting portion 63 of the tip portion 6, and the opening direction of the tip portion 6 can be freely changed by bending the bellows tube 65 in the intermediate portion. It is a shape that can be used. With this configuration, the opening direction of the tip 6 can be changed regardless of the posture of the outer cylinder 4, and what is the orientation of the outdoor end of the drain pipe 2 and the shape of the installation location? Even in this case, the tip portion 6 can be easily connected to the end portion of the drain pipe 2.

It is needless to say that the embodiment of the present invention is not limited to the above-described embodiment and can be appropriately changed without departing from the scope of the idea of the present invention.

The pipe clogging clearing tool 1 according to the present invention can be suitably used when, for example, connecting to the outdoor side end of the drain pipe 2 of an air conditioner to remove foreign matter clogged in the drain pipe 2. ..
