Irrigation system

#This application claims the benefit of PCT Patent Application PCT/US18/52326, filed on Sep. 22, 2018, which claims the benefit of U.S. Utility patent application Ser. No. 15/713,252, filed on Sep. 22, 2017, now abandoned, both applications being incorporated herein by reference.

#Not Applicable.

#This invention relates to irrigation systems, and more particularly to an irrigation system for use in conjunction with a hot tub.

#FIG. 1 is a diagram of the invention;

#FIG. 2 is a diagram of an interface screen of a control system of the invention, illustrating an interface screen of a software application for controlling the irrigation system as being executed on a mobile smart phone;

#FIG. 3 is a diagram of an interface screen of a control system of the invention, illustrating an interface screen for controlling the water pump, water temperature, lighting, and the like, in a spa;

#Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

#Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word “each” is used to refer to an element that was previously introduced as being at least one in number, the word “each” does not necessarily imply a plurality of the elements, but can also mean a singular element.

#FIG. 1 illustrates an irrigation system 10 for use with a hot tub or spa 20 having a water heating circuit 30 and an automatic water fill valve 40 connected to a water source 15 through a source line 16. The source line 16 may optionally include a water softening unit 180 disposed therealong for reducing hard minerals within the water entering the irrigation system 10 through the source line 16. In some embodiments the irrigation system 10 is added to an existing spa 20 having the water heating circuit 30, which is typically an electric heater 37 (FIG. 1), and/or the automatic water fill valve 40 connected with the water source 15. In other embodiments, the irrigation system 10 includes the spa 20, the water heating circuit 30, and the automatic water fill valve 40. The spa 20 may also include a sterilizing apparatus such as an ozone generator 39 (FIG. 1) for sterilizing the water as it circulates throughout the system 10.
