HVAC Exterior Cleaning Pipework

Abstract

The HVAC exterior cleaning pipework is a system attachable to a HVAC unit, such that the PVC pipework can clean the exterior of the unit by means of strategically placed sprayer valves. The pipework is extendable, such that it can expand or retract to meet the exact dimensions of the specific HVAC unit whereon it should be attached. The pipework may be connected directly to a hose with sufficiently pressurized water, or the integrated pump may assist in the flow of water. The spray heads and the pump have removable components whereby they can be cleaned separately when needed.

15. The cleaning device of claim 1, further comprising a clearance of the extendable pipework from the outside of the hvac unit via a length of the plurality of connector straps between the extendable pipework and the hvac unit.

16. The cleaning device of claim 1, further comprising a timer configured to control an operation of the sprayer valves.

17. The cleaning device of claim 1, further comprising a filter configured inline with the extendable pipework.

18. The cleaning device of claim 1, further comprising a filter configured offline with the extendable pipework.

19. The cleaning device of claim 1, wherein the extendable pipework is retractable in regards to a portion of the outside of the hvac unit.

20. The cleaning device of claim 1, wherein the extendable pipework is extendable to a topside and a lateral side of the outside of the hvac unit.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] FIG. 1 is a holistic view of the HVAC exterior cleaning pipework installed on an HVAC unit in accordance with an embodiment of the present disclosure.

[0008] FIG. 2 is a view of the HVAC exterior cleaning pipework, in which it is demonstrated how a built-in pump slightly alters the design of the pipework in accordance with an embodiment of the present disclosure.

[0009] Throughout the description, similar reference numbers may be used to identify similar elements depicted in multiple embodiments. Although specific embodiments of the invention have been described and illustrated, the invention is not to be limited to the specific forms or arrangements of parts so described and illustrated. The scope of the invention is to be defined by the claims appended hereto and their equivalents.

DETAILED DESCRIPTION

[0010] Reference will now be made to exemplary embodiments illustrated in the drawings and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended. Alterations and further modifications of the inventive features illustrated herein and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

[0011] Throughout the present disclosure the term [term] is used to refer to [describe, rest of sentence]. The term [term] refers to [describe, rest of sentence].

[0012] FIG. 1 is a holistic view of the HVAC exterior cleaning pipework installed on an HVAC unit in accordance with an embodiment of the present disclosure. The pipework is comprised primarily of PVC pipe A, which may be either one-half inch or three-fourths inch in diameter. Strategically placed around the pipework are sprayer valves B with removable heads for cleaning. Additionally, there are sliding adjustable connector straps C to connect to the HVAC unit. At one end of the pipework is a small structure to receive the input of water. This structure connects to a water hose at the outlet D, then feeds the water through a pump with a timer E, powered by 110 volts or by solar power. This pump F is capable of exerting thirty to forty pounds of pressure. The pump has a removable plastic jar G for use of cleaning. Lastly, the water flows from the pump through the four inch pipe into the pipework system, to be sprayed onto the HVAC unit.

[0013] FIG. 2 is a view of the HVAC exterior cleaning pipework, in which it is demonstrated how a built-in pump slightly alters the design of the pipework in accordance with an embodiment of the present disclosure. The PVC pipe A that is either one-half inch or three-quarters inch is depicted, similarly to FIG. 1. In this version however, the water from a hose goes through the water hose connector D then to the pump F, with the associated cleaning jar G, which feeds the water out both ends directly into the pipework system. A clearance of the extendable pipework above the HVAC unit provides clearance of irregular surfaces and a spray angle for the sprayer valves thereto. A cleaning fluid includes water and oxidizing and reactive agents formulated to clean dirt and grease from the HVAC unit.

[0014] Although the operations of the method(s) herein are shown and described in a particular order, the order of the operations of each method may be altered so that certain operations may be performed in an inverse order or so that certain operations may be performed, at least in part, concurrently with other operations. In another embodiment, instructions or sub-operations of distinct operations may be implemented in an intermittent and/or alternating manner.

[0015] While the forgoing examples are illustrative of the principles of the present disclosure in one or more particular applications, it will be apparent to those of ordinary skill in the art that numerous modifications in form, usage and details of implementation can be made without the exercise of inventive faculty, and without departing from the principles and concepts of the invention. Accordingly, it is not intended that the disclosure be limited, except as by the specification and claims set forth herein.
