Title: Device and method for washing drinkware

Description:
FIELD OF THE INVENTION 
     This is a patent related to a device for washing drinkware. More particularly, this patent relates to a device for a multi-staged washing drinkware without consuming electricity. 
     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. 
     Therefore, there is a need for a cost-effective drinkware washing device that does not use electricity. 
     There is a need for a simple drinkware washing device that it is easy to fix during break-downs. 
     There is also a need for a drinkware washing device that can provide thorough washings to different sizes, shapes, and types of drinkware. 
     There is a need for alleviating the current waste management problems by avoiding using plastic, paper, or other synthetic material drinkware. 
     The drinkware washing device of the present invention solve the above problems.

     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.

     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.
