DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) Referring to the several views of the drawings, the handheld dishwashing device that is easily transportable, requires a minimal amount of water, and allows for quick and easy cleansing of dishes is shown according to the several embodiments of the invention and is generally indicated as 10.

(11) Referring initially to FIGS. 1-3, the handheld dishwashing device 10 is ergonomically structured for being grasped within a user's hand in a position that allows the user's forefinger to depress an actuator member, which is defined by the trigger 64. The handheld dishwashing device 10 includes a rinse extension bar chamber 76 that slideably captivates a rinse extension bar 66 that extends outwardly from the distal end of the rinse extension bar having chamber 76. A pivot pin 68 connects the rinse extension bar chamber 76 with the handle 62 of the handheld dishwashing device 10 and allows for guided, pivoting movement of the rinse extension bar 66 and chamber 76 about the pin 68 and relative to an elongate member defining the cleaning head extension bar 78 so that the rinse extension bar 66 can be moved towards the cleaning head extension bar 78 to hold the cleaning head 84 while scrubbing and scraping (see broken line illustration in FIG. 1). A spring 77 at the swivel pin 68 urges the rinse extension bar 66 to a relaxed position shown in FIGS. 2 and 3. A thumb grip 70 is ergonomically placed along the rinse extension bar 66 to allow the user to easily extend the rinse extension bar 66 outwardly relative to the chamber 76 by applying pressure to the thumb grip 70. At the distal end of the rinse extension bar 66 is a scraper 72 that can be used to scrape dirty dishes during the cleaning process. A rinse tube water exit 74 is also located at the distal end of the rinse extension bar 66. The rinse extension bar 66 can extend out from and retract within the rinse extension bar chamber 76 to accommodate the user's needs.

(12) Also extending from the handle 62 of the handheld dishwashing device 10 is a cleaning head extension bar 78. Located at the distal end of the cleaning head extension bar 78 is a first reduced hole 80 for the soap mixture 162 to exit and a second reduced hole 82 for the hot water to exit, as shown in FIG. 4. A cleaning head 84 attaches to the distal end of the cleaning head extension bar 78, which includes a cleaning head base 86 and a filter or sponge material 88 suitable for scrubbing dishes. As illustrated, the cleaning head base 86 can freely rotate and has no fixed positions. An optional fabric 90 covers the filter or sponge material 88. Additionally, the cleaning head extension bar 78 and the rinse extension bar 66 can be moved together, as illustrated by the broken lines in FIG. 1, allowing the user to reach narrow areas while cleaning, and the sponge material 88 freely follows the shape of dishes and utensils when being used, thereby enabling a user to clean the dishes and utensils without having to angle the device 10 in awkward positions. The cleaning head 84 pivots into position by itself in response to the pressure applied by the user against the dish or utensil. This pivot action permits the device 10 to alternate between the sponge material 88 and other cleaning surfaces on the cleaning head 84, such as the scraper 103 (see FIGS. 4 and 6) and rubber brush bristles 104 (see FIG. 5), without having to change hand positions and while maintaining the finger on the trigger 64. Multiple embodiments of the cleaning head 84 are contemplated, each of which can be interchangeably attached to the cleaning head extension bar 78, providing the user with a variety of cleaning options.

(13) Referring to FIGS. 4-6, the structure of the cleaning head 84 and its method of attachment to the cleaning head extension bar 78 is shown in accordance with a preferred embodiment. In the embodiment shown in FIGS. 4-6, the cleaning head extension bar 78 includes a male snap-on attachment component 96, generally in the form of a ring, that engages a female snap-on attachment component 98, generally in the form of an annular groove, within female receptacle 92. The receptacle 92 is rotatably held on a swivel rod component 100, allowing the cleaning head 84 to rotate about the swivel rod axis 102, as indicated by the arrows in FIG. 4. A hole 99 in the female receptacle 98 (see FIG. 4) directs the flow of hot water and soap into the filter material (or spongy material) exposed within square opening 106 of the cleaning head base 86.

(14) Several embodiments of the cleaning head 84 are contemplated within the scope of the invention. The cleaning head 84 illustrated in FIGS. 4 and 6 includes the cleaning head base 86 with an integrally formed scraper 103, the array of rubber brush bristles 104 (see FIG. 5), and the filter or sponge material 88 with the filter or sponge material and bristles covered by the optional fabric 90. The user can use the scraper 103 as a traditional scraper or squeegee for wiping the dish clean of grease and food, and then flip the cleaning head 84 to use the sponge material 88 to finish the cleaning process. Use of the scraper 103 prevents the sponge material 88 from contacting grease and food, thereby limiting the amount of water and soap required for the cleaning process. Another embodiment of the cleaning head 84 is illustrated in FIG. 6 and includes an array of rubber brush bristles 104 attached to the cleaning head base 86, and the filter or sponge material 88, but without the optional fabric.

(15) In operation, a water source and soap or soap mixture source are provided and are in communication with the handheld dishwashing device 10 by hand unit water line 50 and hand unit soap line 48, respectively. As shown in FIG. 7, a hand unit connector tube 52 may encase the hand unit soap line 48 and the hand unit water line 50 for preventing the two lines from tangling. Referring to FIGS. 1-3, the hand unit soap line 48 and the hand unit water line 50 enter the handheld dishwashing device 10, and the hand unit soap line 48 travels through the handle 62 and the cleaning head extension bar 78, ending at the first reduced hole 80 (see FIG. 4), allowing the soap mixture to exit onto the cleaning head 84.

(16) The hand unit water line 50 travels through the handle 62, ending at a hot water chamber 114 encased within the handle 62. The hot water chamber 114 is divided into separate chambersa cleaning head hot water chamber 116 and a rinse extension hot water chamber 118by spaced washers 120. A cleaning head hot water line 122 connects the cleaning head hot water chamber 116 with the second reduced hole 82 (see FIG. 4) for the hot water to exit onto the cleaning head 84. A rinse extension hot water line 124 connects the rinse extension hot water chamber 118 with the rinse tube water exit 74, located at the distal end of the rinse extension bar 66.

(17) The trigger 64 controls whether water is taken from the cleaning head hot water chamber 116 or the rinse extension hot water chamber 118. When the trigger 64 is in a relaxed position, as illustrated in FIG. 2, water continuously flows from the cleaning head hot water chamber 116 to the cleaning head hot water line 122 via a hot water exit hole 126, and water is emitted from the reduced hole 82 onto the cleaning head 84. When the trigger 64 is depressed, as illustrated in FIG. 3, the hot water exit hole 126 is displaced, allowing water to continuously flow from the rinse extension hot water chamber 118 to the rinse extension hot water line 124, and water is emitted from the rinse tube water exit 74. When the trigger 64 is released, a spring 128 returns the trigger 64 to its relaxed position, as illustrated in FIG. 2.

(18) Referring to FIG. 7, the handheld dishwashing device 10 is shown in combination with a base unit 20, which is used to heat a pressurized flow of water and to mix and store soap for use by the handheld dishwashing device 10. The base unit includes a heater unit control knob 34, a water holding unit pump knob 36, a heater unit power knob 38, a water toggle switch 40, a pressure reducer control knob 42, and a soap adjustment knob 44. A storage compartment 46 for the accompanying handheld dishwashing device 10 is provided that also serves to catch any water run-off from the handheld dishwashing device 10 after being used. A hand unit drain tube 56 extends outwards from the base unit 20 for draining the excess water run-off within the storage compartment 46. A soap unit compartment 58 located on the base unit 20 can be opened to access a soap mixture tank. Extending from the front side of the base unit 20 are a hand unit soap line 48 and a hand unit water line 50 that connect the base unit 20 with the handheld dishwashing unit 10. Encasing the hand unit soap line 48 and the hand unit water line 50 is a hand unit connector tube 52.
