BACKGROUND ART

Every day, home and restaurants use a large quantity of drinkware such as glasses, cups, mugs, etc. Manual washing of drinkware is time consuming and is not thorough. This is especially true in special occasions such as Thanksgiving, birthday party, graduation party, or Christmas celebrations, Furthermore, working people are too busy to wash drinkware every day.

To solve this problem, home owners or occupants use a washing machine. However, washing machines are expensive and require the use of electricity. The use of electricity increases monthly utilities bills which adds to the total cost. Furthermore, washing machines often breakdown. It is expensive to fix or to replace a broken washing machine with a new one. In the meantime, the use of drinkware continues, which creates inconvenience to the users. Thus, maintenance costs add to the total costs of using washing machines.

Above are the reasons why restaurants seldom use washing machines and hire manual labors or to use plastic or paper drinkware. However, plastic or paper drinkware create an environmental problem because used plastic drinkware need to be classified, disposed of, and recycled. If restaurants and households use plastic or paper drinkware, it adds enormous pressure on the current waste management issues.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present invention.

Now referring to FIG. 1, a 3D diagram illustrating a perspective view of a drinkware washing box 100 in accordance to an embodiment of the present invention is illustrated. In an illustrative embodiment, drinkware washing box 100 includes a base 101, a main body 102, a top rim 103, a first compartment 110, a second compartment 120, and a divider 104 that divides first compartment 110 and second compartment 120. First compartment 110 is mainly hollow and includes a first pushed-down rotary cup cleaning device 112 that provides a first washing for a drinkware. Second compartment 120 is mainly hollow and includes a second pushed-down rotary cup cleaning device 121 for providing a second washing for the drinkware.

Next, referring to FIG. 2, a 3D diagram 200 illustrating a perspective view of components of the drinkware washing box 100 of FIG. 1 in accordance with an embodiment of the present invention illustrated. In one exemplary embodiment, base 101 is a shallow rectangular box with rounded ends and it is divided into a first base section 1011, a second base section 1012, and a third base section 1013. A base top surface 201 having the same shape is placed on top of base 101. Base top surface 201 further includes a first insertion hole 2011 for vertically erecting first pushed-down rotary cup cleaning device 112 and a second insertion hole 2012 for vertically erecting second pushed-down rotary cup cleaning device 121. Other multi-purpose holes 2013 are used to connect base top surface 201 to base 101 using fastening means (not shown) such as screws, pins, fasteners, glue, adhesive, etc. Multi-purpose holes 2013 are also used to drain excess cleaning liquid from second compartment 120 into second base section 1012 and third base section 1013.

Continuing with FIG. 2, a distribution tube network 220 is connected to the handle of second pushed-down rotary cup cleaning device 121 to provide external cleaning liquid to second compartment 120. Distribution tube network 220 is arranged along the edges of interior walls of second compartment 120. A leg assembly 2014 is fastened to top base surface 201 to secure distribution tube network 220 in place. Third base section 1013 has an entry opening 1014 so that distribution tube network 220 can receive cleaning liquid from an external source. An insertion box 210 is inserted snugly into first compartment 110. A plurality of soft bristles 111 are deposited on the entire inner surface area of insertion box 210 and extended outward to scrub the exterior surfaces of a drinkware. For this reason, first compartment 110 has smaller volume than second compartment 120.

Continuing with FIG. 2, in operation, first compartment 110 is used for a first washing and second compartment 120 is for a second washing of a drinkware. When a dirty drinkware such as cups, glasses, mugs, etc. need to be cleaned and washed, the drinkware is first inverted and its interior bottom is pushed down on top of first pushed-down rotary cup cleaning device 112. This creates a pressure upon first pushed-down rotary cup cleaning device 112. In accordance to the present invention, this pressure causes first pushed-down rotary cup cleaning device 112 to rotate in a first direction, e.g., a clockwise direction. The higher the pressure, the faster the rotation. As the drinkware rotates, plurality of bristles 111 cleans the exterior and first pushed-down rotary cup cleaning device cleans the interior of the drinkware. Next, as the drinkware is cleaned and lifted off, the pressure upon first pushed-down rotary cup cleaning device 112 decreases. This causes first pushed-down rotary cup cleaning device 112 to rotates in a second direction, e.g., counter-clockwise, opposite to the first direction.

Continuing with FIG. 1 and FIG. 2, the second washing is provided by second compartment 120 and second pushed-down rotary cup cleaning device 121. The cleaned drinkware is again inverted with its interior bottom pushed down on top of second pushed-down rotary cup cleaning device 121. This creates a pressure upon second pushed-down rotary cup cleaning device 121. In accordance to the present invention, this pressure causes second pushed-down rotary cup cleaning device 121 to rotate in a first direction, e.g., a clockwise direction. The higher the pressure, the faster the rotation. As the cleaned drinkware rotates, cleaning liquid such as water is ejected out the top of second pushed-down rotary cup cleaning device 121 and from distribution tube network 220. Next, as the drinkware is cleaned and lifted off, the pressure upon second pushed-down rotary cup cleaning device 121 decreases. This causes second pushed-down rotary cup cleaning device 121 to rotates in a second direction, e.g., counter-clockwise, opposite to the first direction. The decrease in pressure stop the ejection of cleaning liquid. Consequently, the drinkware is thoroughly washed and rinsed off without using any electrical energy. Thus, the objectives of the present invention are achieved.

Next, FIGS. 3-8 disclose different exemplary embodiments of first pushed-down rotary cup cleaning device 112 and second pushed-down rotary cup cleaning device 121 that facilitate the achievement of the objectives of the present invention.

Now referring to FIG. 3, a diagram 300 of the external view of second pushed-down rotary cup cleaning device 121 is illustrated. In an illustrative embodiment, second pushed-down rotary cup cleaning device 121 is structurally more complicated than first pushed-down rotary cup cleaning device 112 because in the second washing external cleaning liquid is also involved.

At the bottom of handle 301 is an insertion section 3011 for inserting second pushed-down rotary cup cleaning device 121 into insertion hole 2012. The diameter of insertion section 3011 is smaller than handle 301 so that second pushed-down rotary cup cleaning device 121 can be vertically erected perpendicular to base top surface 201.

Continuing with FIG. 3, as alluded earlier, insertion section 3011 and insertion hole 2012 allow the replacement of second pushed-down rotary cup cleaning device 121. When second pushed-down rotary cup cleaning device 121 is worn out or when different types of drinkware are cleaned, Tea cups, champagne glasses, and beer mugs all have different lengths, shapes, and diameters. Other embodiments of second pushed-down rotary cup cleaning device 121 include different lengths and different types and materials of bristles 3034 and different arrangements and geometries of cleaning brush 303, depending on the types of drinkware need to be cleaned. Yet in another exemplary embodiment, cleaning liquid ejecting head 304 can also have bristles together with cavities 3041 for washing the interior bottom of drinkware and for ejecting cleaning liquid.

The majority of spring rod 408 includes a plurality of spiral shaped grooves. Coupling sleeves 410 also has a smaller diameter than cylindrical shaft cover 3021 so that coupling sleeve 410 and enlarged section 4101 are enveloped inside cylindrical shaft cover 3021. The interior of coupling sleeves 410 also includes a plurality of teeth that engage with the plurality of spiral shaped grooves of spring rod 408. This engagement creates the rotation of second pushed-down cup washing device 121 when cleaning liquid ejecting head 304 is pressed down by a downward pressure.

Still continuing with FIG. 4, cleaning brush 303 includes a cylindrical core 3031, an insertion section 3032, pin holes 3033 for lock on with second clevis pins 4102, and plurality of soft bristles 3034. In one exemplary embodiment, plurality of bristles 3034 is arranged in six rows.

Cylindrical core 3031 is hollow and has a diameter slightly smaller than cylindrical shaft cover 3021. Insertion section 3032 rests upon enlarged section 3101 so that cylindrical core 3031 fits snuggly within the interior of cylindrical shaft cover 3021.

Referring still to FIG. 4, cleaning liquid ejecting head 304 has the shape of a half dome and includes cavities 3041. An elongated tube 407 has a proximal end connected to handle 301 and a distal end connected cleaning liquid ejecting head 304 by a bushing mechanism (not shown).

Now referring to FIG. 5A, a perspective diagram 500A of second pushed-on rotary cup washing device 121 with a receiving section 510 is illustrated. In an exemplary embodiment, receiving section 510 includes an opening 511 for receiving an external source of cleaning liquid. In the present application, cleaning liquid is not limited to water, it can be dish soaps, detergent, distilled vinegar, etc.

Next referring to FIG. 5B, a perspective diagram 500B showing internal structure of second pushed-on rotary cup washing device 121 along the longitudinal line AA′ of FIG. 5A is illustrated. In one exemplary embodiment, internally, receiving end 510 includes a chamber 5102 connected to a narrow cavity 5101. Opening 511 is connected to narrow cavity 5101 for transferring the cleaning liquid into narrow cavity 5101. A spout 512 is connected to chamber 5102 for distributing cleaning liquid to distribution tube network 220. Receiving section 510 has the same diameter as cylindrical sheath 3012 so that insertion section 3011 can be slid into the top of receiving section 510.

Continuing with FIG. 5B, elongated tube 407 has a first enlarged section 4071 and first spring retainer 4021. First enlarged section 4071 rests upon the mouth of narrow cavity 5101. The top of first compression spring 402 is stopped by first compression spring retainer 4021.

Next, FIGS. 6-7 disclose different exemplary embodiments of first pushed-down rotary cup cleaning device 112. In an illustrative embodiment, first pushed-down rotary cup cleaning device 112 is structurally simpler than second pushed-down rotary cup cleaning device 121 because in the first washing external cleaning liquid is not involved.

Now referring to FIG. 6, a diagram 600 of the external view of first pushed-down rotary cup cleaning device 112 is illustrated. From the bottom to the top, first pushed-down rotary cup cleaning device 112 includes a handle 601, a shaft 602, a cleaning brush 303, and a top section 604. At the bottom of handle 601 is an insertion section 6011 for inserting first pushed-down rotary cup cleaning device 112 into insertion hole 2011. The diameter of insertion section 6011 is smaller than handle 601 so that first pushed-down rotary cup cleaning device 112 can be vertically erected perpendicular to base top surface 201.

Continuing with FIG. 6, as alluded earlier, insertion section 6011 and insertion hole 2011 allow the replacement of first pushed-down rotary cup cleaning device 112. When first pushed-down rotary cup cleaning device 112 is worn out or when different types of drinkware are cleaned. Tea cups, champagne glasses, and beer mugs all have different lengths, shapes, and diameters. Other embodiments of first pushed-down rotary cup cleaning device 112 include different lengths with different types and materials of bristles 6033 and the geometry and arrangement cleaning brush 603, depending on the types of drinkware need to be washed. In other embodiments of the present application, cleaning liquid ejecting head 304 is made of soft materials such as super soft Styrofoam, soft foams so that it can go through any shapes and sizes of drinkware mouths. In all embodiments, first pushed-down rotary cup cleaning device 112 and second pushed-down rotary cup cleaning device 121 can be used to wash laboratory glassware.

Now referring to FIG. 7, a 3D diagram 700 showing the internal components of first pushed-down rotary cup cleaning device 112 is illustrated. In an exemplary embodiment, handle 601 includes insertion section 6011, a cylindrical sheath 6012, a top threaded section 6013. The top threaded section 6013 has exterior threads located at the top of cylindrical sheath 6012.

Continuing with FIG. 7, shaft 602 includes a spring rod 6024 having a bottom section 6023 that is inserted into cylindrical sheath 6012, a compression spring 6025 enveloping spring rod 6024, a compression spring retainer 6026, a cylindrical shaft cover 6021, a coupling sleeve 701 with an enlarged section 7011, clevis pins 7012, and a pair of covering means 7013-7014 such as plastic caps, bolts, etc. Spring rod 6024 has smaller diameter than cylindrical sheath 6012 and cylindrical shaft cover 6021. The majority of spring rod 6024 includes a plurality of spiral shaped grooves. Coupling sleeves 701 also has a smaller diameter than cylindrical shaft cover 6021 so that coupling sleeve 701 and enlarged section 7011 are enveloped inside cylindrical shaft cover 6021. The interior of coupling sleeves 701 also includes a plurality of teeth that engage with the plurality of spiral shaped grooves of spring rod 6024. This engagement creates the rotation of first pushed-down cup washing device 112 when top section 3604 is pressed down by a downward pressure.

Still continuing with FIG. 7, cleaning brush 603 includes a cylindrical core 6031, an insertion section 6032, pin holes 3033 for lock on with second clevis pins 7012, and plurality of soft bristles 6034. In one exemplary embodiment, plurality of bristles 6034 is arranged in six rows. Each row of bristles 6034 is formed along the longitudinal length of cylindrical core 6031 and at an angle of 60° with respect to other rows. Cylindrical core 6031 is hollow and has a diameter slightly smaller than cylindrical shaft cover 6021. Insertion section 6032 rests upon enlarged section 7011 so that cylindrical core 6031 fits snuggly within the interior of cylindrical shaft cover 6021.

Still referring to FIG. 7, top section 604 has the shape of a half dome and connected to cylindrical core 6031 by a bushing mechanism (not shown). Bushing or connector that connects top section 604 and cylindrical core 6031 is well-known in the art and needs not discussed here.

Now referring to FIG. 8, a perspective 3D diagram 800 illustrating the operating principle of second pushed-down rotary cup cleaning device of FIG. 1-FIG. 5. In second compartment 120, distribution tube network 220 provides cleaning liquid to the interior and exterior of a drinkware 810.

To provide cleaning liquid to the interior of drinkware 810, an input tube 5110 connects external cleaning liquid source, goes through opening 1014, and delivers cleaning liquid to opening 511. Receiving section 510 is slidably coupled to bottom section 3011 through insertion hole 2012. Thus, input tube 5110 is conveniently located in third section 2013 of base 101 and second pushed-down rotary cup cleaning device 121 is erected vertically with cleaning brush 303 near the rim of second compartment 120.

To provide cleaning liquid to the exterior of drinkware 810, an output tube 5120 is located at the bottom of base top surface 201 connecting spout 512 to the remainder tubes of distribution tube network 220. To maximize the available space, distribution tube network 220 includes a plurality of tubes arranged along the interior edges and around the circumference of the top surface of second compartment 120. In an exemplary embodiment, because second compartment 120 is a rectangular box with rounded end, tubes connected together along the edges of second compartment 120 to form a rectangular side tube section 820 that receives cleaning liquid from output tube 5120. A curved tube 821 runs along the rim of the top surface of second compartment 120 and connects the two upper corners of rectangular side tube section 820 to form a semicircle. Tubes which run along the rim of second compartment 120 and form the semicircle includes a plurality of spray holes 8201 where cleaning liquid ejected to wash the exterior of drinkware 810.

Continuing with FIG. 8, in operation, drinkware 810 is inverted and its interior bottom is pushed down on top of cleaning liquid ejecting head 304, creating a downward pressure 801. Downward pressure 801 slides cleaning brush 303 down deep into cylindrical shaft cover 3021. The intimate coupling between internal teeth (not shown) of coupling sleeve 410 and plurality of spiral-shaped grooves of second compression spring rod 408 causes cleaning brush 303 rotate in a first direction 802. Depending on the winding direction of spiral-shaped grooves, first direction 802 can be set to either clockwise or counter-clockwise. As cleaning brush 303 is rotating, it sinks into cylindrical shaft cover 3021, compressing second compression spring 409. At the same time, since insertion section 4081 rests on mid-section cam 4031, bushing 403 compresses first compression spring 402. This increases the pressure inside chamber 5102 and, in turn, causes cleaning liquid to raise quickly in elongated tube 407 along a first current path 803. Finally, cleaning liquid is ejected out of plurality of cavities 3041 into the interior of drinkware 810 by second current paths 804 due to the thinness of elongated tube 407 and high pressure inside chamber 5102. Thus, the interior of drinkware 810 is scrubbed by bristles 3034 and by the cleaning liquid along second current paths 804 as second pushed-down rotary cup cleaning device 121 is rotating in first direction 802.

Continuing with FIG. 8, the cleaning liquid flows inside distribution tube network 220 along rectangular tube frame 820 and curved tube frame 821. The cleaning liquid exits out of distribution tube network 220 by plurality of spray holes 8201 along a third path 805 to clean the exterior of drinkware 810.

Still referring to FIG. 8, after second washing as described above, drinkware 810 is lifted off from cleaning liquid ejecting head 304. As pressure 801 decreases and become a second pressure 802, first compression spring 402 and second compression spring 409 expand, pushing cleaning brush 303 out of cylindrical shaft cover 3021. This force causes cleaning brush 303 to rotate in a second direction 8021. In the meantime, cleaning liquid still cleans the interior and exterior of drinkware 810 by second paths 804 and third path 805 due to the pressurized external cleaning liquid source.

It is within many embodiments of the present invention that a plurality of drinkware washing boxes as described in FIG. 1-FIG. 7 above can be placed next to one another to clean a bucket full of dirty drinkware 810 as the same time. It is also within the scope of the present invention that a valve can be implemented to control the flow of the external cleaning liquid. This valve only opens to allow the cleaning liquid to flow when cleaning liquid ejecting head 304 is pressed down. Otherwise, this valve is closed when pressure 801 is decreased to zero.

Finally, referring to FIG. 9, a method 900 for washing drinkware without using electricity is illustrated. Method 900 is embodied by drinkware washing box 100 described in FIG. 1 and FIG. 2 above. Furthermore, method 900 includes a first washing using first pushed-down rotary cup cleaning device 112 and a second washing using second pushed-down rotary cup cleaning device 121.

At step 901, a first washing is provided by using a first pressure by a drinkware to rotate a vertically erected first cleaning brush in a first direction around the interior of the drinkware. It is within many embodiments of the present invention that the first pressure is varied and proportional to the angular velocity of the first cleaning brush. The harder the pressure, the faster the first cleaning brush rotates, Step 901 is realized by first compartment 110 and first pushed-down rotary cup cleaning device 112. The structure and operation of first pushed-down rotary cup cleaning device 112 are described in details in FIG. 6-FIG. 7 and FIG. 8 respectively. Within many embodiments of the invention described above, as pressure 801 increases, first pushed-down rotary cup cleaning device 112 rotates in first direction 8011 faster. Conversely, as drinkware 810 is lifted off, second pressure 802 decreases, first pushed-down rotary cup cleaning device 112 rotates in second direction 8021 faster because of the kinetic energy stored in compression spring 6025.

At step 902, a second washing with cleaning liquid is provided using a second pressure by the drinkware to rotate a vertically second cleaning brush in a second direction around the interior of the drinkware. Step 902 is realized by second compartment 120 and second pushed-down rotary cup cleaning device 121. The structure and operation of second pushed-down rotary cup cleaning device 121 are described in details in FIG. 3-FIG. 5 and FIG. 8 respectively.

The foregoing description details certain embodiments of the invention. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the invention can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the invention with which that terminology is associated. The scope of the invention should therefore be construed in accordance with the appended claims and any equivalents thereof.
