The present invention relates to a pump, and, more specifically to a self-priming pump that is dedicated to pumping water to water features.
A swimming pool has a filtration pump. The filtration pump of a swimming pool pumps water to the swimming pool and is therefore a key component of the circulation system in a pool. Filtration pumps are typically installed upstream of the pool filter. Because of this, filtration pumps include a strainer basket for removing large debris from the water and preventing the debris from entering the pump.
A swimming pool could also have added water features such as a spa, fountain, waterfall, etc. These water features may have a dedicated pump to provide circulation to that water feature. Pumps that provide circulation to water features are typically installed after the pool filter and therefore do not need a strainer basket. However, in the pool market today, filtration pumps are often used to supply water to the water features which renders the strainer basket of the filtration pump superfluous. Furthermore, there are dedicated water feature pumps without the strainer basket and without the reservoir where the strainer basket is installed. However, without the reservoir, dedicated water feature pumps of swimming pools are not known to self-prime.
Accordingly, there is a need for improvements in the design of water feature pumps where the water feature pumps can self-prime and also prevent a strainer basket from being installed in the water feature pump.
A self-priming dedicated water feature pump is provided. The water feature pump can include a strainer housing connected to a pump housing. The strainer housing is an example embodiment of a priming reservoir, and references herein to the example embodiment of the strainer housing, shall be understood by a person of ordinary skill in the art to also encompass a reference to a priming reservoir more generally. The strainer housing can include a reservoir for allowing water to enter the strainer housing so that the water feature pump can self-prime. The strainer housing can also include a post installed within the reservoir. The post can function to prevent a strainer basket from being installed in the strainer housing. The post can be of sufficient volume and/or geometry to allow enough water to enter the strainer housing so that the water feature pump can self-prime while also preventing a strainer basket from being installed in the strainer housing. A cap can also be installed on the post to prevent a strainer basket from being installed in the strainer housing. The cap can be removable to allow for debris removal.
The foregoing features and others will be apparent from the following Detailed Description, taken in connection with the accompanying drawings, in which:
The present invention relates to a self-priming dedicated water feature pump, as discussed in detail below in connection with
The reservoir 32 can include a removed portion 34. The removed portion 34 can be located on the rear end 22 of the strainer housing 12 which facilitates water to flow from the strainer housing 12 to the pump housing 14. The pump housing 14 can include an outlet 36 so that the flow of water can move from the inlet 30 of the strainer housing 12 through the removed portion 34 into the pump housing 14 and exit the outlet 36. The outlet 36 can be threaded to receive an outflow conduit for directing the flow of water out of the water feature pump 10 to the water features, such as spa jets, waterfall, fountain, deck jet, laminar, bubbler, vanishing edge, etc.
As noted above, the water feature pump 10 also includes the post 18. The post 18 can include a top portion 38, a body 40, and a bottom portion 42. The post 18 can be shaped in a cylindrical fashion or any other suitable shape to accomplish the function of the present disclosure as will be discussed in greater detail below. The bottom portion 42 of the post 18 can be secured to the bottom of the inner wall 29 which abuts the bottom end 26 of the strainer housing 12. The bottom portion 42 of the post 18 can be secured permanently using any suitable mechanism known to those of skill in the art. For example, the post 18 can be integrally formed with the bottom of the inner wall 29 or fastened mechanically with an adhesive, screw, or snap-fit mechanism. The post 18 can alternatively be removable from the reservoir 32 and need not be permanently affixed to the inner wall 29. As will be discussed in greater detail below, removing the post 18, can allow the water feature pump 10 to be converted from a dedicated water feature pump to a traditional filtration pump. The thickness of the body 40 of the post 18 should be a suitable size in relation to the reservoir 32 to allow for a sufficient amount of water to fill into the reservoir 32. The purpose of allowing a sufficient amount of water into the reservoir 32 will be explained in greater detail below.
An alternative embodiment of the post 18 is shown in connection with
In another embodiment, the post 18 can be designed to be removable from the inner wall 29 and reservoir 32. For example, the means for installing the post 18 can be done in a removable manner such by using a screw or a snap-fit mechanism. If such a removable mechanism is used, the post 18 can be removed by unscrewing or snapping out the post 18 from the inner wall 29. Removing the post 18 from the reservoir 32 allows the water feature pump 10 to be transformed from a dedicated water feature pump to a traditional filtration pump. The traditional filtration pump which has no post 18 allows a strainer basket to be installed in the reservoir 32 and therefore can be installed before a filter and can self-prime. If the post 18 was installed in the reservoir 32 by permanently fastening the post 18 to the inner wall 29, then the present disclosure can allow for a strainer basket to be shaped so that the strainer basket can be installed over the post 18 and be within the reservoir 32. For example, the strainer basket could include a long tube that would accept the post 18 and fit within the reservoir 32 as shown in
The water feature pump 10 can function as a dedicated water feature pump that allows for self-priming while also preventing the installation of a strainer basket. A strainer basket may not be needed for the water feature pump 10 because the water feature pump 10 can be installed after the filter to provide circulation to various water features. It may still desirable to include a strainer housing 12 to allow the water feature pump 10 to self-prime. Therefore, the post 18 can be installed within the reservoir 32 of the strainer housing 12 to prevent installation of a strainer basket. The thickness of the body 40 of the post 18 can be a certain amount relative to the size of the reservoir 32 so to allow a sufficient amount of water to enter the reservoir 32 to allow the water feature pump 10 to self-prime. Alternatively, the volume of the post 18 can be such that it allows for a sufficient amount of water to be available in the reservoir 32 to allow the water feature pump 10 to self-prime. The geometry of the post 18 can be any type of geometry known to those of skill in the art to make it difficult to design a new strainer basket that could be retrofitted to the strainer housing 12. Additionally, the cap 44 can be added to the post 18 such that a strainer basket modified to fit in the strainer housing 12 would need to be so small so as to render it useless.
