The present disclosure generally describes fluid pumping devices. More specifically, the present disclosure describes electrically powered motorized pumps with multiple discharge ports.
Electric motor driven utility pumps can use various techniques to move water and other fluids from one location to another. Such pumps operate by drawing fluid into the main pump body and then discharging the fluid through an outlet. The outlet can be attached to a conduit, such as a standard garden hose, to deliver the discharged fluid to a separate location.
Utility pumps typically provide discharge outlets in one of two locations. More specifically, pumps typically employ either a top (axial) discharge outlet 502 as shown in
Described herein are embodiments of systems, methods and apparatus for addressing these shortcomings.
This description includes drawings, wherein:
Corresponding reference characters in the attached drawings indicate corresponding components throughout the several views of the drawings. In addition, elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted or described in order to facilitate a less obstructed view of the illustrated elements and a more concise disclosure.
The present disclosure describes pumps with discharge outlets in multiple locations, for example, on both the top and the side. These pumps take advantage of the benefits, while minimizing the drawbacks, of pumps with only a single discharge outlet.
The present disclosure describes a pump that provides for either top or side discharge capabilities through the use of a unique pump housing design. A user can select the discharge location by attaching a conduit device (e.g., a garden hose) to one discharge outlet and sealing the other discharge outlet. For example, the user can install a threaded cap (which can be tethered to pump, for example, via a tether) onto the other discharge outlet.
Existing top discharge utility pumps 500 (see
The presently described multi-outlet pump 100 combines both of these features into one unique housing 110 that allows for user changeable discharge depending on the application.
Certain embodiments also employ a design that filters debris from the pump. The proposed design reduces clogging during operation by way of multiple sets of progressively reduced openings to filter debris from large too small. This feature also allows for easy, tool-less cleaning of collected debris. That is, the use of multiple sets of progressively reduced openings allows for the filter of debris from large too small.
Existing pumps use various openings, obstructions, and screens to filter debris and reduce pump clogging. For example,
The present disclosure also provides a unique housing design that includes an integrated cord wrap system which serves as handles, plus a molded in feature to allow for hanging during storage.
In some embodiments, the top and side discharge outlets can include or be fitted with quick-release fittings. The quick-release fittings can be configured to automatically close-off the unused discharge outlet and allow for quick attachment to a conduit device, such as a garden hose.
In some aspects, the pump may be cordless, and operate with an interchangeable and rechargeable battery pack. In some examples the battery pack can provide a direct current electrical power supply to the pump.
Some examples of the presently disclosed pump provide a user with the ability to convert easily from a top discharge to a side discharge pump. This allows the user to handle a range of residential water pumping applications with a single product.
In some examples, the presently described pump can be made, at least partially, with injection mold tooling.
Some examples of the presently described pump can be used to remove water from pool covers, small swimming pools, hot tubs, flooded window wells, low spots on lawns, flooded basements, flat roofs, stock tanks, rain barrels, and the like.
An electrical power source supplies electrical power to the motorized pump. The electrical power supply can include an electrical cord for plugging into an AC power supply.
In some embodiments, a battery/battery pack provides a DC power supply as shown in
The battery pack can be removable and/or rechargeable. In some examples, the battery 460 can be recharged via a docking station. In other examples, the battery 460 is rechargeable via a power cord that plugs into the housing. The battery operated pump can be configured to turn on and off via a switch 470 (e.g., a push-button switch) located on the exterior of the pump housing 410 or at the switch plug 903. The switch 470 could include a number of types of activators or switches, including for example, on/off switches (e.g., slide switches, rocker switches, switch nobs, push-button switches, etc.), tilt switches such as float switches, pressure or pneumatic switches, capacitive sensor switches, etc. In still other examples, the battery operated pump 400 could also be set up to automatically start upon detection of the presence of water (e.g., such as by use of a capacitive switch). Additionally and/or alternatively, the pump 400 may include a timer that automatically controls the operation (e.g., the turning on or off) of the pump. The timer can be set so that the pump automatically turns off after being on for a predetermined period of time (e.g., 30 minutes, 1 hour, 2 hours, etc.) so as not to drain more power than necessary. The pump 400 may also be equipped with a sensor to automatically shut the pump off when it determines that it is no longer pumping fluid. The switch 470 (or timer or sensor) is not limited to use on a battery operated pump, and could also be employed on other pumps, including pumps designed to be powered from an AC or DC power source. The switch 470 or timer could also be located at locations away from the pump housing 410. For example, the switch 470 or timer could be located on a power cord that supplies power to the pump 400. Moreover, the power cord could also include a receiver or transceiver (e.g., a radio frequency transceiver) that allows for the remote controllability of the pump 400.
Some examples of the pump have a fluid inlet 150 for drawing fluid into the pump housing 110, and a first discharge outlet 102 for discharging fluid out of the pump housing. The first discharge outlet 102 is adapted to attach to a fluid conduit device. In some examples, the first discharge outlet 102 is positioned on a top portion of the pump 100. The pump 100 also has a first sealing mechanism that seals the first discharge outlet 102 to inhibit discharge of fluid from the first discharge outlet 102 when not in use. The first sealing mechanism can include, for example, a threaded cap 206 (which can be tethered to the pump as shown in
In some examples, the sealing mechanism may include, or be a part of a system that allows a user to selectively seal one or more of the discharge outlets. For example, the sealing mechanism may include a device built in to one or more of the discharge outlets that is in communication with a switch (e.g., a mechanical or electrical switch) or other controller (e.g., a computer or processor). In this way, a user can select to seal or unseal a discharge port by activating/deactivating the corresponding switch. In some examples, switch or other controller, may be accessible remotely or wirelessly so that the sealing mechanism, as well as other features of the multi-use pump, could be operated at a remote distance. For example, the switches can be configured to communicate with a remote controller device, which can be a radio, infrared, Wi-Fi, Bluetooth, or other type of signal transmitter.
The pump comprises a second discharge outlet 104 for discharging fluid out of the pump housing. In some examples, the second discharge outlet 104 is positioned on the side of the pump 100. The second discharge outlet is adapted to attach to a fluid conduit device.
A second sealing mechanism seals the second discharge outlet to inhibit discharge of fluid from the second discharge outlet when not in use. The second sealing mechanism, can also include a threaded cap 106 (which can be tethered to the pump) or a quick-release fitting 108. The pump 100 has a second internal fluid flow path 116 between the fluid inlet 150 and the second discharge outlet 104.

Referring again to
The pump 100 may include an electrical power outlet opening 103, which can be configured to receive or otherwise mate with a power cord to provide power to the pump 100. In some examples, the opening 103 is configured to provide a water-proof connection to a water-proof power cord.
Some examples of the pump 100 include a cord-wrap mechanism 112 that facilitates winding of an electrical cord around the pump housing. In one example, the cord-wrap mechanism 112 comprises a plurality of protuberances extending from the pump housing 110. One or more of the protuberances can comprise, or operate as a handle to facilitate handling of the pump. In some forms, the handle and cord-wrap mechanism 112 are integrated into a common structure so that the protuberance forms both a handle and a portion of a cord-wrap mechanism. In still other examples, the pump 100 may have a separate handle integrated into and/or attached to the pump 100. For example,
Some examples of the pump 100 also include a hanging apparatus 118 (see
In some examples, the pump 100 comprising a filter system that filters debris from the motorized pump. The filter system can include a plurality of concentric filter levels, including, for example, filter rings (122, 124, 126), and/or legs 128, each concentric filter level having a plurality of filter openings (123, 125, 127, 129), wherein the filter openings (e.g., 123) of an outer concentric filter ring (e.g., 122) are larger than the filter openings (e.g., 125, 127) of any inner concentric filter ring (124, 126) so that at least some smaller debris that can pass through an outer concentric filter ring is filtered by an inner concentric filter ring.
In some aspects, at least one filter ring (122, 128) is a component of the pump housing 110, as shown in
Other embodiments further include a housing that is configured with a first mating structure that allows accessories to be attached or removed from the pump. For example, in one form the pump housing defines a socket within which the above mentioned tethered tool may be stored for tightening and loosening the sealing mechanism. In other forms, housing attachments or accessories, such as leg extenders or handles may be attached to either stabilize the pump or allow it to be dropped into sumps or other recessed areas more easily. In some forms, some of the above mentioned features may also be attached to the pump with such a mating structure in order to allow the pump to be customized as desired by the user. For example, the above-mentioned cord wrap structures, handles and/or hooks could connect to the pump housing using a mating structure, such as a friction fit tongue and groove configuration. In this way, they could be moved about the pump housing to be placed in an orientation desired by the user or replaced with alternate accessories (e.g., different shaped hook receptacles, longer legs or foot members, etc.).
In some examples, the pump and/or the pump housing can include foot members 140 that support the stability of the pump. In some aspects, the foot members 140 can be adapted so that accessories such as the above-mentioned leg extensions can be connected, thereby expanding the diameter of the base of the pump 100 to provide even further stability.
The present disclosure also relates to methods of pumping fluid. In particular, the present disclosure describes examples of methods and techniques from pumping fluid in from multiple outlets in a pumping apparatus.
The method 800 involves pumping fluid from multiple outlets in a fluid pumping apparatus, which can be any of the pumping apparatuses described herein. In some examples, the pumping apparatus has a pump and a pump housing, and two discharge outlets. Each of the discharge outlets may have a sealing mechanism that serves to seal the outlet when not in use, but to allow free flow of fluid out of the outlet when in use. In some examples, the two outlets can be placed on opposite sides of the pumping apparatus. In other examples, the outlets are placed on different sides of the apparatus so as to pump in two different (e.g., perpendicular) directions. For example, one outlet may be on the top of a pumping apparatus, and the other can be on the side of the apparatus. The pump has at least two internal flow paths in the housing that connects an inlet to each of the discharge outlets.
The method 800 can include attaching 810 a fluid conduit to a first discharge outlet. This attaching can serve to unseal the first sealing mechanism and establish a fluid connection with the conduit. In some aspects, the step of unsealing may occur prior to the attaching of the conduit. For example, unsealing the outlet may first involve removing a cap from the discharge outlet.
Using a sealing mechanism, the second discharge outlet is also sealed 820 to inhibit, obstruct and/or prevent fluid from being discharged from the second discharge outlet. Sealing can include placing a threaded cap over the second discharge outlet, or using an internal sealing mechanism (e.g., similar to a seal in a quick-release mechanism) to maintain a seal of the discharge outlet. In some examples, step 820 may not require an active step. For example, when the outlet defaults to a sealed position, step 820 may simply include maintaining the second outlet in a sealed position. In some examples, the sealing mechanism can be built into the discharge outlet and activated by way of a switch (e.g., a mechanical or electrical switch), that allows the user to select which discharge outlet to use without having to actively seal or close that specific outlet.
Next, the pump is operated 830 to draw fluid into the pump housing through the inlet. The fluid is then directed 840 from the fluid inlet, through a first internal fluid flow path in the housing, and toward the first discharge outlet. Because the second discharge outlet is sealed, fluid will not be directed toward that outlet. Fluid is then discharged 850 from the first outlet, through the conduit, as desired by the user.
Because the method 800 contemplates using multi-outlet pumps, the method 800 may further comprise additional steps that allow for the pumping of fluid out of the second port. In this manner, the method 800 may include disconnecting 860 the conduit from the first outlet, and subsequently re-sealing the first outlet. In some examples, a significant amount of time may elapse between step 850 and step 860, such that the two steps are each performed as part of separate pumping tasks. In some examples, the disconnecting 860 of the conduit may serve to automatically seal the first outlet, for example, by using a quick-connect sealing mechanism to automatically seal the first discharge outlet so that the pump will not discharge fluid from that port.
A conduit is then attached 870 to the second discharge outlet, thereby establishing a fluid connection between the second discharge outlet and the inlet. The attaching 870 of the conduit may serve to unseal the second discharge outlet itself, but in some examples, a separate step of unsealing may be necessary. For example, it may be necessary to remove a cap that was previously sealing the second discharge outlet.
In some examples, the same conduit that was previously attached to the first discharge outlet (e.g., in step 810) may be used to connect to the second discharge outlet in step 870. However, in other examples, different conduits may be used. Further, in some examples, each discharge outlet may be configured to use different types of outlets, such as outlets having different mating parts or conduit diameters.
Fluid is then pumped 880 into the inlet and through the second flow path toward the second discharge outlet. The fluid is then discharged out of the second outlet 890, through the conduit. In this way, the pump can be used to discharge fluid from different outlets. In some examples, wherein the fluid discharged from the second discharge outlet (e.g., in step 890) is discharged in a direction perpendicular to the direction of fluid discharged from the first port (e.g., in step 850). In other examples, for example, where the discharge ports are arranged on opposite ends, the discharge directions can be parallel to one another.
It should be noted that the example described above involves attaching a conduit to the discharge outlets prior to fluid being discharged therethrough. However, not all embodiments will require the connection of a conduit, as fluid may simply be projected away from the outlet. In this manner, the discharge outlet may utilize a switch, lever, or other technique to maintain the outlet sealing mechanism in an unsealed position.
Moreover, some embodiments can determine which of the multiple outlets to discharge fluid based on other techniques that are not based on which outlet has a conduit attached. For example, it may be possible in some embodiments to have conduits connected to all outlets, without rendering those discharge outlets functional or active. For example, the pump may include a selector mechanism that, in addition to the caps and connection mechanisms described above, could further include a switch, a lever, a toggle, a valve, an actuator, or another selector device that determines (or allows a user to determine) which of the discharge outlets will discharge fluid during operation of the pump, even if all outlets are attached to a conduit. For example, the selection mechanism could include a valve that opens and/or closes one or more of the internal flow paths of the pump that directs fluid from the inlet to each of the various discharge outlets.
In this way, methods for controlling a multi-flow pump may include providing a pump having an inlet, and at least a first outlet, a second outlet. The provided multi-flow pump would also have a mechanism for selecting which of the first outlet and second outlet fluid will through. The method further includes moving the mechanism between a first position for allowing fluid to flow through the first outlet and a second position for allowing fluid to flow through the second position. For example, the method may include utilizing a first outlet obstruction and a second outlet obstruction in the pump. The obstructions may be placed in the internal fluid flow paths of within the pump housing. The method may involve moving the mechanism between the first position and second position comprises, respectively, such that the second outlet obstruction engages with the second outlet to obstruct the second outlet and prevent fluid from flowing through the second outlet when the mechanism is in the first position. Further, the method can include moving the first outlet obstruction into engagement with the first outlet to obstruct the first outlet and prevent fluid from flowing through the first outlet when the mechanism is in the second position.
The moving of the mechanism can be performed manually by a user, such as by sliding a lever or pressing toggle mechanism, or the moving could be performed automatically and/or electronically, such as by a controller or computer operated device. For example, the controller can be configured to automatically move a lever, valve, actuator, obstruction device, or the like in response to receiving a signal or command. Additionally and/or alternatively, the controller may effect movement of the mechanism in response to making a determination to change the discharge flow outlets. Such a determination could be based on a variety of factors or combinations of factors, such as the detection (using sensors) of the amount of flow into and/or out of the pump, a detection of the amount of time (using a timer) that monitors how long the pump is operating, and/or algorithms that monitor pumping features such as pumping speed, power, efficiency, flow rate, flow volume, etc.
Additionally and/or alternatively, the pump could be configured so that some or all of the outlets are capable of discharging fluid even if there is no conduit attached thereto. In some situations, the pump can be configured so that more than one of the pump outlets discharge fluid simultaneously, regardless of whether or not a conduit is attached thereto.
The present figures show pumps with dual outlets for purposes of simplicity of description. It should be understood that the described technology could include three or more outlets, depending on the size, shape, and construction of the pump. In any case, the pump will have the ability to pump from one outlet, or a selection of multiple outlets, among all of the outlets on the pump itself. For example, pumps may include three, four, or even five discharge outlets, and can be configured so that only one of the outlet discharges fluid during operation, so that some of the outlets discharge fluid during operation, or so that all of the outlets are discharging fluid during operation.
Some embodiments may incorporate one or more features of the Wayne Water Systems ISP50 pump, which is described in U.S. patent application Ser. No. 10/233,832, filed Aug. 29, 2002, now U.S. Pat.
