BACKGROUND OF THE INVENTIONField of the Invention
The present invention relates to a dishwashing apparatus and, more particularly, to a portable dishwashing apparatus having a base unit and an accompanying hand unit that allows for easy, one-handed operation of the dishwashing apparatus, and requires a minimal amount of water, which can be accessed from direct hook up to plumbing or from within its own contained water supply.
Discussion of the Related Art
Over the years, automatic dishwashers have become commonplace in households in the United States, and provide a convenient method of cleaning and sterilizing dishes and eating utensils. Typically, dirty dishes are loaded into the dishwasher, which, in operation, sprays heated water at 130-150 degrees Fahrenheit onto the dishes. A detergent and water mixture is then used to clean the dishes, followed by clean water to remove the detergent residue. While such represents the typical dishwashing cycle process in both residential and commercial dishwashers alike, a number of advances have been made in recent years in an effort to further enhance the cleansing capabilities of dishwashers, such as the use of multiple wash and rinse cycle periods as well as the inclusion of rinsing aids.
A considerable drawback of traditional automatic dishwashers is the large amount of water required during each wash and rinse cycle. Such a negative characteristic becomes readily apparent when an automatic dishwasher is used when it is not filled to full capacity, which is likely to occur in households of one to three persons. Furthermore, a number of situations may present themselves to an individual who may have dirty dishes but is in a location lacking a automatic dishwasher. For example, a college dorm room rarely comes equipped with a automatic dishwasher, however, college students often utilize micro-refrigerators that include an attached microwave, which is used to heat entire meals. Consequently, college students must either purchase disposable paper plates and plastic eating utensils or engage in the cumbersome task of hand washing the dirty dishes.
Only a few dishwashing devices have been developed that can be used in a portable fashion. A number of these portable dishwashing devices are non-electric, and are powered by water pressure alone. For example, U.S. Pat. No. 4,542,756 discloses a portable non-electric dishwasher system that is especially suited for insertion within a sink and includes an enclosed dish-holding container, and is entirely reliant on the water pressure supplied by an outside source. Suspended throughout the interior of the enclosure is a series of expansible water bladders having multiple apertures for spraying water on the dirty dishes. With the application of the pressurized water, the bladders expand, which effectively scrubs the dirty dishes. The continued expansion of the bladders eventually triggers an outflush of water from the apertures, thus rinsing the dirty dishes. This scrub and rinse cycle continues over a period of time as determined by the user.
U.S. Pat. No. 5,518,014 discloses a portable countertop dishwasher that is electrically powered and structured for placement alongside a sink. The portable countertop dishwasher includes a housing cavity with a fluid handling assembly contained therein and having an upper pump and a lower pump, each within its own housing. In operation, the pumps distribute fluid amongst the dishes within the housing cavity, with an outlet conduit serving to release the fluid from the housing.
While the portable dishwashing devices described above are useful for their intended purpose, there remains a need for a more practical and efficient electrically powered portable dishwashing apparatus that is easily transportable, requires a minimal amount of water, and allows for quick and easy cleansing of dirty dishes. The present invention seeks to address the limitations and shortcomings of presently known portable dishwashing devices, as well as to effectively minimize the amount of water that is wasted during the cleansing process.
The present invention provides a portable dishwashing apparatus that includes a base unit having means to heat water that is supplied from a conventional plumbing system via attachment or, alternatively, supplied from a portable water holding tank in connection with the base unit. The present invention utilizes a hand unit having a cleaning head that is in connection with the base unit's heated water supply, and is equipped to brush, scrape, and wash dishes and utensils.

It is still a further object of the present invention to provide a portable dishwashing apparatus which is adapted to clean one dish in a matter of seconds with no wasted water and considerably less energy uses as compared to other conventional dishwashing systems and methods.
It is still a further object of the present invention to provide a portable dishwashing apparatus that provides hot water in a matter of seconds, with no water wasted while waiting for the water to heat to the desired temperature, and further wherein the apparatus is able to maintain a selected water temperature throughout use.
It is yet a further object of the present invention to provide a portable dishwashing apparatus that is adapted to soap and rinse at the same time, thereby saving time, energy and water.
It is still a further object of the present invention to provide a portable dishwashing apparatus that is structured to direct hot water directly into a cleaning head while helping to keep food and germs out of the cleaning head.
It is still a further object of the present invention to provide a portable dishwashing apparatus that provides a pivotable and rotatable cleaning head that receives a flow of hot water and soap mixture, and wherein the cleaning head surface remains hot even when turned upside down.
It is still a further object of the present invention to provide a portable dishwashing apparatus that provides a hand unit with a cleaning head and a rinse extension arm, and wherein the rinse extension arm is structured and disposed to be used for holding the cleaning head in position.
It is yet a further object of the present invention to provide a portable dishwashing apparatus as set forth above, and wherein the cleaning head is structured and disposed for wiping, scraping and scrubbing dishes, pots, pans and the like.
These and other objects and advantages of the present invention are more readily apparent with reference to the detailed description and accompanying drawings.
SUMMARY OF THE INVENTIONThe present invention is directed to a portable dishwashing apparatus that is easily transportable, requires a minimal amount of water, and allows for quick and easy cleansing of dishes. The portable dishwashing apparatus includes a base unit having means to heat water that is supplied from a conventional plumbing system or other water flow supply source via attachment or, alternatively, supplied from a portable water holding tank in connection with the base unit. The water, whether supplied via a conventional plumbing system, other water flow supply source or from the portable water holding tank, is heated by a heater unit located within the base unit. A soap mixture tank containing heavily concentrated soap is located within the base unit of the portable dishwashing apparatus, and serves to mix and store the heated water and concentrated soap mixture. The present invention utilizes a hand unit having a cleaning head that is in connection with the base unit's heated water supply and soap mixture tank, and is equipped to brush, scrape, and wipe dish surfaces, and to further apply the heated water and soap mixture in order to wash dishes and utensils. The hand unit also provides a clean and rinse function to rinse the soapy water from the cleaned dishes and utensils.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSReferring to the several views of the drawings, the portable dishwashing apparatus 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.
In each of the embodiments of the invention, the portable dishwashing apparatus 10 includes a base unit 20 and a hand unit 60. Referring to
Referring to
Referring to
Also extending from the handle 62 of the hand unit 60 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
Referring to
Several embodiments of the cleaning head 84 are contemplated within the scope of the invention. The cleaning head 84 illustrated in
In operation, a water source is provided by the holding tank inlet tube 130 extending from the portable water holding tank 110, which is plugged into the holding tank water inlet connection 24. Additionally, or in the alternative, the direct line inlet tube 132 can be connected to a conventional plumbing system at the direct water supply inlet connection 22 to serve as a water source. Referring to
The holding tank inlet tube 130 and the direct line inlet tube 132 converge at a valve 138, which controls whether water is received from the holding tank inlet tube 130 or the direct line inlet tube 132. The user controls the valve 138 with the water inlet valve knob 26 located on the base unit 20. Thereafter, the water flows in a cold water line 140 from the valve 138 to the heater unit 142. The water enters the heater unit 142 and is heated by the heater coils 144. A filter material 146 helps to even the flow of water through the heater. The water then exits the heater unit 142 via the hot water exit tube 148, where a thermometer 150 calculates the temperature of the water. The thermometer display 54 located on the base unit 20 displays the temperature calculated by the thermometer 150 to the user.
The hot water exit tube 148 then flows to a T-splitter 152, which splits the water into two separate lines—the hand unit water line 50 and the soap tank water line 154. The hand unit water line 50 travels directly out of the base unit 20 and enters the hand unit connector tube 52. The soap tank water line 154 approaches a soap tank valve 156, which controls the amount of water that enters the soap mixture tank 158. The soap tank valve 156 is controlled by the soap adjustment knob 44 located on the base unit 20. The water enters the soap mixture tank 158 and comes into contact with a soap concentrate, forming a soap mixture 162. The user can access the soap mixture tank 158 and replace the soap concentrate by opening the soap unit compartment 58 located on the base unit 20 and removing a cap 159 on the top of the soap mixture tank 158. Once the mixture tank 158 is filled with soap concentrate to the appropriate replacement level, the cap 159 is replaced and the compartment is closed. As more water enters the soap mixture tank 158, the level of the soap mixture 162 rises until reaching a soap fill level 164, at which point the soap mixture 162 begins to enter a soap exit tube 166, which is located within the soap mixture tank 158, through a V-cut 168 at the top of the soap exit tube 166. The soap mixture 162 then enters the hand unit soap line 48, which exits the base unit 20 and enters the hand unit connector tube 52. A soap drain valve 170 can be opened to release (i.e. drain) excess soap mixture 162 from the soap mixture tank 158 via a soap drain tube 30 that leads to a sink exit tube 193 (see
The hand unit connector tube 52 encases the hand unit soap line 48 and the hand unit water line 50 and extends from the base unit 20 to the hand unit 60. Referring to
Upon entering the hand unit 60, 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 chambers—a cleaning head hot water chamber 116 and a rinse extension hot water chamber 118—by 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
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
A power cord 176 with accompanying power plug 178 extends out of the base unit 20, supplying power to the portable dishwashing apparatus 10. A water holding unit pump switch 172 is included within the base unit 20 for actuating water flow from the portable water holding tank 110 to the portable dishwashing apparatus 10, and is controlled by the water holding unit pump knob 36 located on the base unit 20. A heater unit power switch 174 controls the power supplied to the heater unit 142, and is regulated by the heater unit power knob 38 located on the base unit 20. A heating control switch 180, which is regulated by the heater unit control knob 34 located on the base unit 20, controls the temperature of the heater coils 144.
