DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, a preferred embodiment of a drainage pipe passage apparatus is designated at 10. This device 10 is, for example, a wet/
A suitable pressure/vacuum source, such as a dry vacuum cleaner 12, a pressure/vacuum control manifold 14, and a working hose 16 for communication with a drain 18 are included.

Vacuum cleaner 12 includes an upright container 20 having an electric motor-driven fan 22 . The fan 22 draws vacuum into the interior 26 of the container or canister 20 through an inlet port 24 and into the canister 20 through an outlet port 28.
It is used to exhaust air from the

The wet-dry vacuum cleaner operates to draw dirt into the canister 20 through the vacuum port 24 while exhausting air from the interior of the canister 20 through the pressure port 28. The pressure/vacuum control manifold controls the drain opening device to selectively apply pressure or vacuum to drain I8 via work hose 16.

The control manifold 14 includes an upright block housing 30 formed of any suitable material, such as hard plastic or cast aluminum. The control manifold has a vacuum duct 32 and a pressure duct 34 inside.
and a conical vacuum sleeve 36 and a pressure sleeve 3 on the outside.
8, and these sleeves are respectively connected to a vacuum port 24 and a pressure port 28 of the vacuum cleaner.

Vacuum duct 32 and pressure duct 34 combine to form an upwardly extending three-way pressure/vacuum duct 40. The three-way pressure/vacuum duct 40 defines an access port 42 located on the top surface 44 of the manifold. Front wall 46 has openings 4850 that communicate with internal vacuum and pressure ducts, respectively, for drawing air into and exhausting air from the canister during postfilling operations. It fulfills its role.

Further controls manifold pressure/vacuum flow to working hose 1
6. The control mechanism has a pivot axis 52 that extends horizontally through the manifold and lies along the top of a partition 56 separating internal vacuum duct 32 and t-chaduct 34. . Pivot shaft 52 is pivotally mounted between front wall 46 and rear wall 50 of the manifold and includes a projection 60 extending a short distance from front wall 46 .

A plate-shaped valve or damper 62 is supported on the surface of the pivot shaft 54 and projects radially therefrom to restrict the flow by blocking either the internal vacuum duct 32 or the pressure duct 34. It is directed through the three-way duct 40 and the working hose 16.

The shape of the blade valve 62 matches the inner wall surfaces of the vacuum duct and the pressure horn duct, and makes airtight contact at the junction of these ducts to prevent pressure loss during operation. Control mechanism 52 further includes a movable cover 64. This movable cover 64 selectively closes the opening 48.50 in the front wall 46. The movable cover is connected to the pivot shaft 54 by an extension rod 66 and can be pivoted between the openings. A suitable knob 68 is attached to the cover 64 to facilitate operation of the cover.

The blade valve 62 and the extension londo 6 are in the same plane so that when the blade valve covers, for example, the pressure duct 34, the pressure opening 50 is not closed. This relationship also holds true for the vacuum duct 32 and the vacuum opening 48.

In operation, control mechanism 52 is first set to one position, such as the position shown in solid lines in FIGS. 2 and 3. In this position, air is forced out of the vacuum cleaner via the pressure duct 34 and the pressure opening 50. On the other hand, the outer cover 64 closes the vacuum opening 48 and opens the vacuum duct 32, and air is drawn into the vacuum cleaner via the hose 16. This arrangement of valve 62 ensures the drawing of a partial vacuum through the working hose 16 and the application of the vacuum to the clogged drain. By reversing the position of the handle and control mechanism (to the dotted position in FIG. 3), pressure is now applied to the service water bath and drain pipe. As indicated by the dotted line in FIG. 3, air is forced through the pressure duct 34 into the working hose and reaches the drain pipe. On the other hand, the open vacuum port 48 admits ambient air into the control system.

By periodically operating this control mechanism, differential pressure pulsations are applied and the drain pipe is effectively opened.

Similarly, the control mechanism can be applied to other appliances or devices, such as automobile radiators, marine engines, etc., to clean the fluid flow paths of these devices.

The present invention is also useful in cleaning swimming pools or winterizing them. It can be used in particular for water filtration applications in swimming pools to drive out water and debris in circulation lines.

If desired, a drain cleaning aid fluid, such as a cleaning agent or pressurized water, can be introduced through the hose fitting 17 using an applicator 19 as shown in FIGS. 1 and 4.

Figures 4 and 5 illustrate a variation of the invention in which the supply of water is accompanied by a pulse of positive pressure in the system to assist in opening a drain or similar member. It is. A handheld nozzle 70 is now attached to the hose fitting 17 and has a suitable fitting 72 for receiving the water supply hose.

This nozzle includes a suitable valve 74 and has a trigger 76 for water supply. Additionally, the trigger 76 is part of an electrical circuit 78 that includes a control manifold solenoid 80 shown in FIG. Activation of the trigger supplies water to the drain and moves the solenoid actuated movable cover 66 to positive pressure mode. Releasing this trigger interrupts the water supply and applies a vacuum pulse to the drain. If desired, this nozzle can be used for detergent,
It can be used to supply degreasing agents etc. to the drain.

In another variation of the invention illustrated in FIGS. 6 and 7, a control manifold 90 includes an upright block-shaped housing 92 having an interior chamber 94 and a movable housing 92 for directing pressure and vacuum pulses to a closed drain. blade valve or damper 96.

It terminates in an inlet/outlet sleeve 108. The upper portions of the front and rear walls follow the shape of the tapered side wall portion 102a. The inner surfaces 110 of both tapered side walls immediately below the inlet/outlet sleeve are beveled to form a sealing surface for engagement with upper sealing surfaces 112 on opposite sides of the blade valve. Operation hose 11 fitted in the population/outlet sleeve
3 leads to vacuum and pressure pulses to the drain.

The control manifold also includes an internal partition 114 that includes spaced apart partition walls 116. These partition walls 1
16 is vertically oriented and extends between and is attached to the front and rear walls. This internal partition is molded integrally with the control manifold. The upper edge of each partition wall is beveled to form a sealing surface that engages the lower sealing surface 120 of the blade valve. Additionally, a stop shoulder 121 is located at the upper edge of each partition wall to limit movement of the blade valve. The partition wall cooperates with the front wall to direct air into and out of a single inlet/outlet port 122 in the front wall.

The lower end of the pressure chamber and the lower end of the vacuum chamber have an outlet port 123 and an inlet port 125, respectively, for connection to corresponding ports on a vacuum cleaner as substantially shown in FIG.

The approximately rectangular blade valve shown in FIG.
includes. This valve plate 124 has a hollow pivot hub 126
Main portion 124a along pivot axis A-A defined by
and a sub-portion 124b. The pivot hub is generally cylindrical and integrally formed with a valve plate of a suitable material, such as polypropylene. This pivot hub receives a pivot shaft 1211. Pivot axis 128 includes pivot openings 1 in front wall 104 and rear wall 102.
Assembled into the manifold at 30.132. A handle member 134 is fitted onto the free end of this pivot shaft and operates the blade into vacuum and pressure positions.

As shown in FIG. 6, the control manifold has a blade valve that closes the pressure chamber so that in its activated state the vacuum cleaner sends vacuum pulses to the inlet sleeve 10g and the operating hose 1.

The blade valve includes a spring member 136 (FIG. 7) fitted between the pivot shaft and the front wall, which causes the blade valve to rotate under the influence of a differential pressure acting on the blade valve (solid line position in FIG. 6) in the vacuum mode. Resisting the tendency to move. Instead of this,
A ball/catch structure between the front wall 104 and the working handle 134 could be used to positively position and hold the blade valve in both the pressure and vacuum positions.

8 and 9 show a variation of the pressure/vacuum manifold of FIG. 6. This type of manifold 90 includes a housing 92, an interior chamber 94, and a damper 96 that directs pressure pulses and vacuum pulses to a closed drain. This damper 96 is moved by an operating handle 138 into a vacuum position (solid line) or a pressure position (dotted line). Pivot axis 14
0 is mounted between front wall 142 and rear wall 144 and receives damper 96 as shown in FIGS. 6 and 7. The first and second levers 146 and 148 are fitted onto the ends of a pivot shaft extending between the front and rear walls and are joined at one end by a laterally extending gripping handle 150. The other ends of these levers extend from the pivot axis and provide balance to the operating handle. An abutment or stop 152 is provided on the outer surface of the front and rear walls to limit movement of the operating handle without stressing the blade valve. Stop member 152 is preferably integrally molded with the front and rear walls. The operating handle is weighted to counter the tendency of the blade valve 96 to move counterclockwise (see FIG. 8) due to the pressure difference between the vacuum surface 96a and the pressure surface 96b. This pressure differential is sufficient to maintain the operating handle in pressure mode (dotted line in Figure 8). The operating handle itself shall have a durable structure suitable for rapidly switching the unit from pressure mode to vacuum mode. Other components shown in FIGS. 8 and 9 are the same as those in FIG. 6, and are designated with corresponding symbols.

FIG. 1O shows yet another modification of the invention. The drain opener in this variation includes a pressure/vacuum control manifold and a container for connection to a canister-type dry or wet-dry vacuum cleaner.

The drain opener includes an intermediate canister or receiver 156 that receives the effluent from the vertical drain 18 and a pressure/receiver.
It includes a vacuum control manifold 90 and a canister dry or wet-dry vacuum cleaner 15g. This arrangement allows pressure/vacuum pulses from a pressure/vacuum source, such as a canister vacuum cleaner 158, to the vertical drain 18 without requiring a source vacuum cleaner to receive effluent from the vertical drain. It is possible to communicate with each other. This effluent is received and retained in intermediate canister 156.

This variation includes a pressure/vacuum control manifold 90 as described above with respect to FIGS. 8 and 9.

As mentioned above, this pressure/vacuum manifold 90 directs pressure or vacuum pulses through hose 113 to the clogged vertical drain 18.

The intermediate canister includes a bucket 160 of a suitable capacity, such as 5 gallons, and a snap fitting 16 on the side.
4 and a securely fitted top cover 162 held in place by 4. The top cover includes fittings that form a vacuum line 166 and a pressure line 168.

The vacuum pipe line 166 has a circular port L66a on its top surface,
An upwardly facing elbow fitting 166b is connected to the vacuum cleaner vacuum port 158 via a suitable hose 16g. circular port 1
66a and the vacuum elbow fitting 166b are attached to the inside of the bucket 1.
It opens at 70.

The pressure line 16g also has an upwardly facing elbow fitting 168 similar to the circular port 168a and the vacuum line elbow fitting.
b. However, the pressure line further includes a direct connection between the elbow fitting and the circular port to direct pressure pulses from pressure source 158p through hose 172, pressure line 168, manifold 90, and to the vertical drain via hose 113. Conduit connection 168c is included.

In other words, the interior of the bucket is not exposed to pressure pulses.

To operate the embodiment shown in FIG. 10, the operating handle 150 is first set to vacuum mode (solid line) and a vacuum pulse is delivered to the clogged drain by the vacuum source 158v. $170 of the bucket is exposed to the vacuum created by the vacuum source. In this mode of operation, the effluent drawn from the drain is collected in a bucket. By simply reversing the operating handle to pressure mode (dotted line),
Pressure pulses are directed from the pressure source to the drain via pressure lines, manifolds, and hoses 113. Once the drain has been cleaned, the effluent in the canister can be disposed of by removing the top cover.

If desired, liner 171 (FIG. 11a) is inserted into container 160.
(FIG. 1O) or for the collection and disposal of effluent received by container 20 (FIG. 1). Preferably, the liner is made of a thick sheet metal material or a highly rigid material so that it can maintain its shape even in vacuum mode.

Figures 11a and ub show another variant of the invention. In these variations, the pressure/vacuum manifold 1
80 is disposed in a horizontal position within the outer housing 182 of the drain opening device. A motor-driven header 184 within the outer housing is connected 186 to the manifold.
188 provides a source of pressure P and a source of vacuum V. The housing includes a base plate 190 and an outer cover 192 mounted on a receiver 194 to receive runoff from a closed drain with a liner 171. A control damper 196 is mounted within the manifold of the pivot shaft 198 and divides the interior chamber 200 into a pressure chamber 202 and a vacuum chamber 204. Preferably, the damper and its pivot shaft are integral and molded from a suitable plastic material. ■
A handle 206 is fitted onto the opposite end of the pivot shaft to operate the damper. slot 210
The knob 20g attached to this handle through the handle becomes a grip and is used to operate the damper.

In operation, the damper is normally in the position shown in FIG. 11a, or pressure mode, and incoming pressurized air opens the damper and directs pressure through the intake/outlet port to the drain. In the embodiment shown in FIGS. 1-10, the damper is moved from a vacuum mode to a pressure mode to sequentially apply a vacuum pulse and a pressure pulse to the drain.

As shown in FIG. 11b, the operating handle is inserted into the slot 21.
The vacuum mode is suppressed by a ring 214 fixed to the housing adjacent to 0. This restraining ring 214 is attached to a base member 216 fixed to the howling.

This ring slides over the knob and holds the damper in the vacuum position against the force of pressurized air directed to the atmosphere through the exhaust port. In this position, the drain release device connects the receiver 1 via the three-way duct 220 and the vacuum chamber 200.
94 is used for wet vacuum work on the collected waste.

FIG. 11b shows a force cup 222 particularly suitable for the present invention.
shows. Force cup 222 includes a hemispherical upper portion 224 that is shaped to define an opening 226 in communication with three-way duct 220 . The force cup edge around opening 226 forms a flange, shown at 228, to facilitate connection with the three-way duct. The opposite end 230 of the hemispherical portion is
It has an integral hollow neck wall portion 232 of decreasing diameter converging toward an open end 234 . The force cup is integrally molded of rubber or a suitable rubber substitute and is operated in vacuum mode, especially in section 11b.
It has sufficient strength to withstand the vacuum when used in the wet vacuum mode of the figure and sufficient elasticity to conform to various drain shapes.

In operation using a drain release device with a receiver liner,
It is desirable for the liner to maintain its shape within the receiver so that it does not interfere with the vacuum drawn from the receiver.

As shown in Figure 11a, the liner has a pleated side wall 1.
71a is provided to maintain the strength of this side wall so that it will not collapse during work. Furthermore, double-sided tape 171c is fitted to the liner bottom wall 171b, and the liner is attached to the receiver bottom wall 19.
Install it on 4a. As another means of maintaining liner shape, manifold connections 188 extend well into receiver 194 to direct air flow to liner bottom wall 171b.

The manifold connections 188 preferably extend to a depth of at least half the depth of the receiver, the length of which is selected by the user or manufacturer to determine the amount of effluent that can be received by the receiver. As the level of effluent rises to the point that it covers the open lower end 189 of connection 188, the airflow characteristics of the device will change and the change in motor pitch will alert the operator to the receiver. This safety measure ensures that no effluent flows through the vacuum intake connection 186 and into the blower 184. .

The present invention has been described above as utilizing a commercially available household wet-dry vacuum cleaner. However, the present invention is not limited thereto, and generally applies to any drain opening specifically designed for commercial or industrial use as long as the pressure/vacuum source and its control mechanism are suitable for the drain opening application. It can be used for devices. In such embodiments of the invention, higher horsepower drive motors are used to achieve levels of pressure/vacuum greater than those obtained with wet-dry vacuum cleaners, making them suitable and suitable for drain cleaning in commercial and industrial applications. may be required. Similarly, the invention is particularly suited for cleaning automotive radiators, cleaning marine engines, and other applications.
