Description
AN APPARATUS FOR CLEANING A CONDUIT
FIELD OF THE INVENTION
The present invention broadly relates to an apparatus for cleaning a conduit such as a gutter, also called a rainspout, a sewer or any type of pipe system.
More particularly, it relates to a rain gutter cleaning apparatus.
BACKGROUND OF THE INVENTION
The gutters of a building which are filled up and obstructed with dirt and leaves are commonly hand-cleaned, using a ladder to reach the gutters. As can be very easily understood, this method of cleaning could be very dangerous.
Other types of conduits such as sewers or the pipe system of a whirlpool may rapidly fill up with impurities which could be very difficult to remove, even impossible to clean.
US 5,421,904 is concerned with a drain pipe having a nozzle body and a hole at an end wall for allowing fluid to pass through. This drain pipe comprises a nozzle body configured to effectively clean the lateral right angle segment or segments of drain pipes which are hidden and unseen from a longitudinally disposed drain pipe segment or conduit employing high pressure fluid.
US 4,795,495 teaches a cleaning device having an inlet nozzle assembly at one end and a sealed nozzle assembly at the other end. The device was conceived mainly to break up clogs in the sewer and thus to improve cleaning of the latter.
US 3,678,948 is concerned with a device for cleaning pipe lines, the device having a nozzle portion. The nozzles are fixed at a certain angle so to clean the interior of the pipe line more efficiently. One feature of the device is that the forward nozzles have an angle greater than the rearward nozzles.

It would be advantageous to provide an apparatus that allows a conduit of the type having a drain outlet such as a rain gutter to be rapidly, simply and effectively cleaned at low cost. Hence, there is presently a need for such a device.
SUMMARY OF THE INVENTION
An object of the present invention is to propose an apparatus for cleaning a conduit that satisfies that above-mentioned need.
In accordance with the present inventian, that object is achieved with an apparatus for cleaning a conduit. The apparatus comprises a hose adapted to be mounted inside and along the conduit. The hose has a first end with an inlet for receiving a cleaning fluid under pressure; a plurality of outlet nozzles disposed along the hose and being designed so to project flushing jets of the cleaning fluid towards a drain outlet of the conduit to thereby sweep any dirt therein towards the drain outlet. The hose also has a closed second end to further increase the pressure of the fluid under the effect of reversed pressure.
The apparatus further comprises a plurality of brackets to mount the hose inside the conduit spaced apart from an inner wall of the conduit.
In a preferred embodiment, the apparatus further comprises an inner pipe mounted coaxially within the hose spaced apart from an inner wall of the hose.
In that case, the inner pipe has a first end with an inlet defining the inlet of the hose; and a second end having an outlet disposed nearby the second end of the hose. Thus, the cleaning fluid under pressure received through the inlet of the inner pipe flows directly towards the second end of the inner pipe, exits the outlet thereof where it hits the closed second end of the hose and flows back towards the first end of the hose and exits through the nozzles at high pressure.
The present invention is also directed to the combination of a rain gutter with an apparatus for cleaning a conduit as described hereinabove.
A conduit cleaning apparatus according to the present invention is thus believed to be very efficient and simple to clean a conduit.
That and other aspects of the present invention will become more apparent in the following description of the invention, particularly when considered in conjunction with the accompanying drawings in which like parts are indicated by like numerals.

DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1 to 4 illustrate an apparatus (2) according to a first preferred embodiment of the invention mounted in a rain gutter (4) which commonly becomes rapidly filled with dirt or leaves.
Referring to figures 1 to 3, the rain gutter (4) consists of a conduit having a U-shaped cross-section and a drain outlet (12) located in the bottom of the gutter (4). The apparatus (2) comprises an elongated hose (6) having a first end (8) opposite a second end (10). The hose (6) is devised to extend in the rain gutter (4) with its second end (10) disposed near an extremity (13) of the gutter (4) and its first end (8) disposed either in the drain outlet (12) or, as illustrated, on the other side of the drain outlet (12) with respect to the extremity (13) of the gutter (4). The hose (6) is preferably hanging within the gutter (4) by means of a plurality of pipe brackets (14) having their extremities (5) hooked to the upper edges (7) of the gutter (4), as shown in FIG. 1.
The first end (8) of the hose (6) is provided with an inlet (16) for receiving a cleaning fluid under pressure. The cleaning fluid may be simply water, a cleaning solution or compressed air. The first end (8) of the hose {6) may be simply connected to a garden hose or a compressor.
Still referring to Figures 1 to 3, the hose (6) is provided along its length with a plurality of outlet nozzles (18) all pointing substantially towards the first end (8) of the hose (6), thereby delivering flushing jets of fluid directed towards that first end (8), and thus towards the drain outlet (12) of the gutter (4). As can be appreciated, the jets of fluid are thus sweeping all the dirt along with them.
The second end (10) of the hose (6} is closed, preferably with a cap (20) to increase and maintain the pressure of the flushing jets under the effect of reversed pressure, as the flow of fluids hits the closed second end (10).
As can be appreciated from FIGS. 2 to 4, the configuration of the nozzles (18) 5 along the length of the hose (6) is precisely adapted to the cleaning of a gutter.
More particularly, the nozzles (18) are disposed following three lines, two lines extending respectively on the left side (15) end of the right side (17) of the hose (6), as best seen in FIGS. 2 and 4, and the third line extending on the bottom (19) of the hose (6), as shown in FIG. 4.
The nozzles (18) disposed on each side (15,17) of the hose (6) are preferably equally spaced apart along the length of the hose (6) and each nozzle (18} on one side (15) is facing a nozzle (18) on the other side (17). The nozzles (18) on the bottom (19) of the hose (6) are disposed along the hose, halfway between two consecutive side nozzles (18). This particular configuration allows the fluid coming out from the bottom nozzles (18) to first sweep the dirt located on the bottom (21 ) of the gutter (4) and bring it upwards to thereby be swept by the side nozzles (18) and so on towards the drain outlet (12).
As best seen in Fig. 3, the hose (6) may comprise a further nozzle (23), preferably of the shower type, located near the first end (8) thereof and devised to be disposed above the drain outlet (12) of the gutter (4) to assure the accumulated dirt to drop down the pipe drain of the gutter (4). Should the end of the gutter (4} be extended to reach the end of the roof, other nozzles (25), preferably smaller than the other nozzles (18), will be installed on the hose (6) to prevent any accumulation of dirt in that extended portion. The nozzles are preferably made of brass or PVC and are of the finger or flat type.
Referring to figures 2 to 4, in order to prevent excessive pressure on the cap (20) of the second end (10) and vibration in the hose (6), a conical deflector (22) is mounted on the cap (20). The conical deflector (22) has a circular base (24) fixed to the inner wall of the cap (20) and a tip (26) pointing towards the first end (8) of the hose (6). As can be appreciated, the flow of fluid under pressure hitting the conical deflector (22) besides being reversed, is uniformly distributed inside the hose (6), thereby reducing the pressure acting directly on the cap (20) and preventing vibration of the hose (6).
Preferably, and for a better deflecting efficiency, a conical cap (28) on which a propeller (30) is rotatively mounted, as best seen in Figure 7, is mounted on the tip (26) of the conical deflector (22). The conical cap (28) is adapted to be snapped on the tip (26) of the deflector by means of mating circular grooves (32).
The hose (6) is preferably made of ABS, PVC, copper or any other material suitable for a pipe. The diameter of the hose (6) is chosen according to its particular use. For example, the diameter of a hose used to clean a gutter is approximately 3l4 inch.
Also preferably, a valve may be mounted at the first end (8) of the hose (6) for controlling the pressure and the flow of the fluid. A soap reservoir already known in prior art, may also be operatively connected to the first end (8) of the hose (6) in order to clean the conduit with a cleaning solution.
Referring now to FIGS. 5 and 6, a second preferred embodiment of the present invention is illustrated. Advantageously, this embodiment may be used where the initial pressure of the fluid used is very low or where the supply in fluid is restricted. Therefore, this second embodiment is designed to further increase and maintain the fluid pressure of the jets at a relatively low cost.
More particularly, as shown in FIGS. 5 and 6, this second embodiment comprises the same elements as the first embodiment described hereinbefore but further comprises an inner pipe (36) coaxially mounted within the hose (6).
The inner pipe (36) has an inlet (16) for receiving the fluid under pressure.
In that case, the inlet of the inner pipe (36) defines the inlet of the hose (6).
The inner pipe (36) also has an outlet (38) disposed near the end wall of the hose (6) defined by the cap (20), whereby the fluid under pressure enters the hose (6) from the inlet of the inner pipe (36), then flows through it and exits from the outlet (38) of the inner pipe (36) where it hits the end wall of the cap (20) and flows back towards the first end (8) of the hose (6) and exits through the nozzles (18) at high pressure. In order to further increase and maintain the pressure within the hose (6), a wall (40) surrounding the inner pipe (36) is mounted within the hose (6) near the first end (8) thereof, as shown in FIG.
6.
That wall (40) consists of a cap provided with a central hole sized to sealingly receive the inner pipe (36).
Also, as an option, a heating tape or cable, already known in prior art, may advantageously be installed around the hose to thaw any accumulated ice in the gutter or conducts.
Although the present invention has been explained hereinabove by way of a preferred embodiment thereof, it should be understood that the invention is not limited to this precise embodiment and that various changes and modifications may be effected therein without departing from the scope or spirit of the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1 to 4 illustrate an apparatus (2) according to a first preferred embodiment of the invention mounted in a rain gutter (4) which commonly becomes rapidly filled with dirt or leaves.
Referring to figures 1 to 3, the rain gutter (4) consists of a conduit having a U-shaped cross-section and a drain outlet (12) located in the bottom of the gutter (4). The apparatus (2) comprises an elongated hose (6) having a first end (8) opposite a second end (10). The hose (6) is devised to extend in the rain gutter (4) with its second end (10) disposed near an extremity (13) of the gutter (4) and its first end (8) disposed either in the drain outlet (12) or, as illustrated, on the other side of the drain outlet (12) with respect to the extremity (13) of the gutter (4). The hose (6) is preferably hanging within the gutter (4) by means of a plurality of pipe brackets (14) having their extremities (5) hooked to the upper edges (7) of the gutter (4), as shown in FIG. 1.
The first end (8) of the hose (6) is provided with an inlet (16) for receiving a cleaning fluid under pressure. The cleaning fluid may be simply water, a cleaning solution or compressed air. The first end (8) of the hose {6) may be simply connected to a garden hose or a compressor.
Still referring to Figures 1 to 3, the hose (6) is provided along its length with a plurality of outlet nozzles (18) all pointing substantially towards the first end (8) of the hose (6), thereby delivering flushing jets of fluid directed towards that first end (8), and thus towards the drain outlet (12) of the gutter (4). As can be appreciated, the jets of fluid are thus sweeping all the dirt along with them.
The second end (10) of the hose (6} is closed, preferably with a cap (20) to increase and maintain the pressure of the flushing jets under the effect of reversed pressure, as the flow of fluids hits the closed second end (10).
As can be appreciated from FIGS. 2 to 4, the configuration of the nozzles (18) 5 along the length of the hose (6) is precisely adapted to the cleaning of a gutter.
More particularly, the nozzles (18) are disposed following three lines, two lines extending respectively on the left side (15) end of the right side (17) of the hose (6), as best seen in FIGS. 2 and 4, and the third line extending on the bottom (19) of the hose (6), as shown in FIG. 4.
The nozzles (18) disposed on each side (15,17) of the hose (6) are preferably equally spaced apart along the length of the hose (6) and each nozzle (18} on one side (15) is facing a nozzle (18) on the other side (17). The nozzles (18) on the bottom (19) of the hose (6) are disposed along the hose, halfway between two consecutive side nozzles (18). This particular configuration allows the fluid coming out from the bottom nozzles (18) to first sweep the dirt located on the bottom (21 ) of the gutter (4) and bring it upwards to thereby be swept by the side nozzles (18) and so on towards the drain outlet (12).
As best seen in Fig. 3, the hose (6) may comprise a further nozzle (23), preferably of the shower type, located near the first end (8) thereof and devised to be disposed above the drain outlet (12) of the gutter (4) to assure the accumulated dirt to drop down the pipe drain of the gutter (4). Should the end of the gutter (4} be extended to reach the end of the roof, other nozzles (25), preferably smaller than the other nozzles (18), will be installed on the hose (6) to prevent any accumulation of dirt in that extended portion. The nozzles are preferably made of brass or PVC and are of the finger or flat type.
Referring to figures 2 to 4, in order to prevent excessive pressure on the cap (20) of the second end (10) and vibration in the hose (6), a conical deflector (22) is mounted on the cap (20). The conical deflector (22) has a circular base (24) fixed to the inner wall of the cap (20) and a tip (26) pointing towards the first end (8) of the hose (6). As can be appreciated, the flow of fluid under pressure hitting the conical deflector (22) besides being reversed, is uniformly distributed inside the hose (6), thereby reducing the pressure acting directly on the cap (20) and preventing vibration of the hose (6).
Preferably, and for a better deflecting efficiency, a conical cap (28) on which a propeller (30) is rotatively mounted, as best seen in Figure 7, is mounted on the tip (26) of the conical deflector (22). The conical cap (28) is adapted to be snapped on the tip (26) of the deflector by means of mating circular grooves (32).
The hose (6) is preferably made of ABS, PVC, copper or any other material suitable for a pipe. The diameter of the hose (6) is chosen according to its particular use. For example, the diameter of a hose used to clean a gutter is approximately 3l4 inch.
Also preferably, a valve may be mounted at the first end (8) of the hose (6) for controlling the pressure and the flow of the fluid. A soap reservoir already known in prior art, may also be operatively connected to the first end (8) of the hose (6) in order to clean the conduit with a cleaning solution.
Referring now to FIGS. 5 and 6, a second preferred embodiment of the present invention is illustrated. Advantageously, this embodiment may be used where the initial pressure of the fluid used is very low or where the supply in fluid is restricted. Therefore, this second embodiment is designed to further increase and maintain the fluid pressure of the jets at a relatively low cost.
More particularly, as shown in FIGS. 5 and 6, this second embodiment comprises the same elements as the first embodiment described hereinbefore but further comprises an inner pipe (36) coaxially mounted within the hose (6).
The inner pipe (36) has an inlet (16) for receiving the fluid under pressure.
In that case, the inlet of the inner pipe (36) defines the inlet of the hose (6).
The inner pipe (36) also has an outlet (38) disposed near the end wall of the hose (6) defined by the cap (20), whereby the fluid under pressure enters the hose (6) from the inlet of the inner pipe (36), then flows through it and exits from the outlet (38) of the inner pipe (36) where it hits the end wall of the cap (20) and flows back towards the first end (8) of the hose (6) and exits through the nozzles (18) at high pressure. In order to further increase and maintain the pressure within the hose (6), a wall (40) surrounding the inner pipe (36) is mounted within the hose (6) near the first end (8) thereof, as shown in FIG.
6.
That wall (40) consists of a cap provided with a central hole sized to sealingly receive the inner pipe (36).
Also, as an option, a heating tape or cable, already known in prior art, may advantageously be installed around the hose to thaw any accumulated ice in the gutter or conducts.
