## Background
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates generally to deposit removal and, more particularly, to an apparatus for introduction a descaling agent to remove mineral deposits, such as calcium carbonate (or “limescale”), from water pipes and valves in a washing machine.
Description of the Prior Art
The use of conventional, modern washing machines (or “laundry machines”) to wash clothes using water and detergent (and sometimes bleach) and then extract much of the water therefrom is well known. Through ordinary use of conventional washing machines, however, mineral deposits often build up in its conduits, such as pipes and valves, generally resulting in a decrease of efficiency and efficacy of the washing machine. As mineral deposits typically cannot be removed by merely flushing the conduits with water, common methods of eliminating the problem in washing machines often include removing or replacing pipes. While the general use of descaling agents is known, it is often difficult to properly introduce them to the pipes and valves used by a washing machine to enable optimal efficacy.
As a result, a problem which still exists is that simply pouring a descaling agent, such as the CLR® Calcium, Lime & Rust Remover, into a washing machine fails to optimize descaling efficacy. Thus, there remains a need for an apparatus for introducing a descaling agent to the water input conduits and facilitating the removal of mineral deposits therefrom. It would be helpful if such a washing machine descaler introduction apparatus enabled a descaling agent to simultaneously be introduced to both the hot and cold water inputs of the washing machine. It would be additionally desirable for such a washing machine descaler introduction apparatus to allow an descaler to be automatically introduced to the washing machine at a controlled pace to maximize the descaling agents' efficacy.
The Applicant's invention described herein provides for an apparatus adapted to allow a user to deliberately introduce a quantity of a descaling agent to the pipes and valves in a washing machine through both water inputs. The primary components in Applicant's washing machine descaler introduction apparatus are a dispensing receptacle, a dispensing valve member, and a diverter. When in operation, the washing machine descaler introduction apparatus enables more effective and efficient cleaning of the conduits of a washing machine. As a result, many of the limitations imposed by prior art structures are removed.
SUMMARY OF THE INVENTION
A washing machine descaler introduction apparatus for introducing a descaling agent to the water inlets of a conventional washer and dryer at a controlled rate. The washing machine descaler introduction apparatus comprises a dispensing receptacle, defined in the preferred embodiment as a dispensing bag, with an attached dispensing valve assembly and an attachable diverter. In use, the dispensing bag, full of a descaling agent, is hung from an elevated position above a convention washing machine with the valve handle of the dispensing valve assembly in the closed position, fully covering the outlet pipe of the dispensing valve assembly with a the closing member. The hot water inlet conduit and the cold water inlet conduit of the washing machine are then each connected to one of the outlet tubes of the diverter. Once a hole is opened for ventilation, the valve handle is moved out of the closed position, moving the closing member partially or fully off of the outlet pipe, thereby enabling the descaling agent to exit the bag and be directed into the hot water inlet conduit and the cold water inlet conduit at a rate that is controlled by how unobstructed the outlet is with respect to the closing member. The descaling agent can then work its way through the washing machine, which is typically run during this process, at a controlled pace to optimize its descaling activity.
It is an object of this invention to provide an apparatus for introducing a descaling agent to the water input conduits and facilitating the removal of mineral deposits therefrom.
It is another object of this invention to provide a washing machine descaler introduction apparatus that enables a descaling agent to simultaneously be introduced to both the hot and cold water inputs of the washing machine.
It is yet another object of this invention to provide a washing machine descaler introduction apparatus that allows an descaler to be automatically introduced to the washing machine at a controlled pace to maximize the descaling agents' efficacy.
These and other objects will be apparent to one of skill in the art.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings and in particular FIGS. 1, 2A and 2B, a washing machine descaler introduction apparatus is shown as a dispensing receptacle and having an attached dispensing valve assembly 110 and an attachable diverter 120. In the preferred embodiment, the dispensing receptacle is defined as a reinforced dispensing bag 101 having a reinforced upper section 102 and a tapered bottom section. It is contemplated that the lower area in the dispensing bag 101, below the reinforced area, is filled with a conventional descaling agent, such as the CLR® Calcium, Lime & Rust Remover, which is to be dispensed from the bag 101, through the valve assembly 110 and the diverter 120, into the pipes of a washing machine (not shown). In addition, said lower area is detachable and disposable from the reinforced section 102.
The dispensing bag 101 includes a mounting aperture 103 that allows the dispensing bag to be hung from a hook or other structure and a reinforced air outlet 104 for being punctured and providing through the puncture an air hole that ventilates the bag 101 when fluid is exiting. It is contemplated that an air hole can be punctured in the air outlet 104 by a puncture tool 105 having an elongated edge.
The dispensing valve assembly 110 is defined by a closeable outlet pipe having a threaded interior surface 111 extending from the front of the dispensing bag 101 and a sliding closing member 112 on the interior of the bag 101 connected to a valve handle 113 that extends outside the bag 101 for selectively opening and closing the outlet pipe of the dispensing valve assembly 110.
The diverter 120 is defined by a splitting connecting member having a threaded outer base surface 121 and two threaded outlet tubes 122. The diverter 120 is constructed to engage the threaded interior surface 111 of the dispensing valve assembly 110, forming a fluid tight attachment, and split fluid exiting the dispensing valve assembly 110, dispensing it from both of the outlet tubes 122.
Referring now to FIGS. 1, 2A, 2B, 3, and 4, when the washing machine descaler introduction apparatus 100 is in use, the dispensing bag 101, full of a descaling agent, is hung from an elevated position above a convention washing machine, typically from a hook 130 through the mounting aperture 103. Prior to use, it is contemplated that the valve handle 113 will remain in a closed position, as shown in FIG. 1, with the closing member 112 fully covering the outlet pipe of the dispensing valve assembly 110. The hot water inlet conduit and the cold water inlet conduit of the washing machine are then each connected to one of the outlet tubes 122. The puncture tool 105 is then used to open a hole in the air outlet 104 and then the valve handle 113 is moved out of the closed position, moving the closing member 112 partially or fully off of the outlet pipe of the dispensing valve assembly 110, thereby enabling the descaling agent to exit the bag 101 and be directed into the hot water inlet conduit and the cold water inlet conduit at a rate that is controlled by how unobstructed the outlet pipe of the dispensing valve assembly 110 is with respect to the closing member 112.
The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
