Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Application No. 62/049,433, filed on Sep. 12, 2014. The entire disclosure of the above application is incorporated herein by reference. 
     
    
     FIELD 
       [0002]    The present disclosure relates to a food waste disposer discharge treatment device and, more particularly, to a food waste disposer discharge treatment device that introduces additives directly into a discharge stream of a food waste disposer. 
       BACKGROUND 
       [0003]    The present disclosure relates generally to a food waste disposer discharge treatment device, and more particularly, to a treatment device that passively introduces additives directly into the discharge stream of a food waste disposer. For example, in the case of a food waste disposer connected to a septic system, the additives may include septic chemicals, bio-enzymes, micro-organisms, and/or other substances to aid the septic system. For further example, in the case of a food waste disposer connected to a composting system, the additives may include micro-organisms, bacteria, and/or other composting aids or substances for the composting system. 
         [0004]      FIG. 1  shows a prior art food waste disposer  100  coupled with an injection device  102  that introduces chemicals in liquid form into the food waste disposer 100. Such a prior art device is disclosed in U.S. Pat. No. 5,856,173 (Riley et al.), which is incorporated herein by reference. 
         [0005]    The food waste disposer  100  is mounted to a sink, such as a kitchen sink, and comminutes food scraps into particles small enough to safely pass through household drain plumbing. The food waste disposer  100  includes an upper food conveying section  104 , a lower motor section  106 , and an intermediate grinding section  108  disposed between the food conveying section  104  and the motor section  106 . The food conveying section  104  includes a first inlet  110  at its upper end for receiving food waste and water in a direction “A”. The food conveying section  104  also includes a second inlet  112  for receiving food waste and water in a direction “B” discharged from a dishwashing machine (not shown). The food conveying section  104  conveys food waste and water to the grinding section  108 , and the injection device  102  injects chemicals in liquid form into the grinding section  108 . The particulate waste, the injected water, and the injected chemicals are mixed and discharged through a discharge outlet  114  in a direction “C”. 
         [0006]    The prior art injection device  102  includes a bottle  116  integrated with a pump  118 , a bottle receiver  120 , and an electromagnetic actuator  122 . The bottle  116  is integrated with the pump  118  of the type that is commonly used to dispense fluid substances such as hand lotion, liquid detergent, and window cleaning fluid. The bottle  116  has a bottle cap  124  for filling the bottle  116  with chemicals. The bottle  116  is secured to the bottle cap  124  fitted into the bottle receiver  120 . The bottle  116  has a pump operating tubular member  126  extending out of a collar portion  128  of the bottle cap  124 . The upper part of the tubular member  126  terminates in a discharge cap  130 . The discharge cap  130  is connected to the interior of the grinding section  108  through a flexible tube  132 . The tube contains a check valve  134  to ensure that water that enters the grinding section  108  cannot enter the pump  118 . When the tubular member  126  is plunged downward, the pump  118  dispenses a small predetermined quantity of chemicals in liquid from the bottle  116  through the discharge cap  130  and the flexible tube  132  into the interior of the grinding section  108 . 
         [0007]    The electromagnetic actuator  122 , secured to a bracket  136 , provides the mechanical force to the pump  118  to dispense a small predetermined quantity of chemicals in liquid form from the bottle  116 . When energized, the electromagnetic actuator  122  drives a rod  138  downward, so the tubular member  126  of the pump  118  plunges downward and correspondingly brings about ejection of a small predetermined quantity of chemicals in liquid form out of the bottle  116  into the food waste disposer  100 . Every time the food waste disposer  100  is turned on to carry out a grinding operation, the electromagnetic actuator  122  executes one pumping stroke to inject a small predetermined quantity of chemicals in liquid form into the food waste disposer  100 . 
         [0008]    As shown in  FIG. 1 , prior art injection devices, such as injection device  102 , employ a complex system of tubing, pumps, and electromagnetic actuators resulting in food waste disposers with such injection devices being more expensive. Further, such injection devices cannot generally be retrofitted to existing food waste disposers, thereby requiring replacement of the entire food waste disposer upon installation. Also, the electromagnetic actuator  122  uses electricity in its operation, increasing the operating cost. Additionally, the predetermined quantity of liquid chemicals dispensed by the injection device  102  may be insufficient during longer grinding operations while excessive and wasteful during shorter grinding operations, potentially creating environmental concerns. Further, such injection devices  102  dispense only liquids and not solids. 
       SUMMARY

       DETAILED DESCRIPTION 
       [0025]    Example embodiments will now be described more fully with reference to the accompanying drawings. 
         [0026]      FIG. 2  shows a discharge treatment device  200  that passively introduces additives directly into a discharge stream  202  from a food waste disposer  204  mounted to a sink  206 , such as a kitchen sink. For example, in the case of a food waste disposer connected to a septic system, the additives may include septic chemicals, bio-enzymes, micro-organisms, and/or other substances to aid the septic system. For further example, in the case of a food waste disposer connected to a composting system, the additives may include micro-organisms, bacteria, and/or other composting aids or substances for the composting system. The additives for the composting system may, for example, enhance or accelerate the breakdown of food waste material collected in a compost collection tank prior to being transferred to a compost pile. The discharge treatment device  200  is shown retrofitted to the food waste disposer  204  through a tail pipe  208  connected to a discharge outlet  210  of the food waste disposer  204 . For example, an inlet of the discharge treatment device  200  is connected to a discharge outlet  210  of the food waste disposer  204  through a tail pipe  208 . Alternatively, the inlet of the discharge treatment device  200  may connect directly to the discharge outlet  210  of the food waste disposer  204 . Alternatively, an inlet of the discharge treatment device  200  may connect to the sink  206  directly. As shown in  FIG. 2 , an outlet of the discharge treatment device  200  is connected to a drain pipe  212 . The drain pipe  212  may be connected to a septic system (not shown), that includes a septic tank or to a composting system (not shown), that includes a compost collection tank. No modification of the food waste disposer  204  and the downstream plumbing is necessary. 
         [0027]    As shown in  FIG. 2 , the discharge treatment device  200  may be installed between the discharge outlet  210  of the food waste disposer  204  and a plumbing trap (not shown). In other words, in  FIG. 2 , the discharge treatment device  200  is installed on the upstream side of plumbing trap located in the plumbing for the sink  206 . Alternatively, the discharge treatment device  200  may be installed on the downstream side of the plumbing trap located in the plumbing for the sink  206 . In the case of the discharge treatment device  200  being installed downstream from the plumbing trap, the plumbing trap may contain any odor from the additives in the discharge treatment device  200  and prevent any such odor from traveling upstream through the food waste disposer  204  and into the sink  206 . 
         [0028]    The discharge treatment device  200  holds at least one pellet  214  that contains additives to be introduced into the discharge stream  202  from the food waste disposer  204 . As discussed above, the additives may include may include septic chemicals, bio-enzymes, micro-organisms, and/or other substances to aid a connected septic system and/or may include may include micro-organisms, bacteria, and/or other composting aids or substances for a connected composting system.  FIG. 2  shows the discharge treatment device  200  holding one pellet  214 . The discharge treatment device  200  passively introduces the additives directly into the discharge stream  202  when water from the discharge stream  202  comes into contact with the pellet  214  and dissolves at least part of the pellet  214 . Water in the discharge stream  202  has at least two sources. Water may enter the food waste disposer  204  from a faucet  216  assembly from a direction “A,” along with food waste introduced into the food waste disposer  204  from the sink  206 . Water may also enter the food waste disposer  204  from a dish washing machine (not shown) in a direction “B” through a dishwasher discharge line  218 , along with food waste introduced into the food waste disposer  204  from the dish washing machine. Because the discharge treatment device  200  is located downstream from the discharge outlet  210  of the food waste disposer  204 , the discharge treatment device  200  is able to passively introduce additives into the discharge stream  202  during each dishwasher cycle and each food waste disposer  204  cycle independently. 
         [0029]    When water in the discharge stream  202  from the food waste disposer  204  in a direction “C” comes into contact with the pellet  214  of the additives in the discharge treatment device  200 , at least part of the pellet  214  dissolves in the discharge stream  202 . A mixture  220  of the discharge stream  202  and the additives exits the discharge treatment device  200  into the drain pipe  212  in a direction “D.” As the pellet  214  erodes with each flow of water, the pellet  214  feeds downward by force of gravity until the pellet  214  is completely dissolved. A user may add a new pellet  214  to the discharge treatment device  200  when necessary, such as when the pellet  214  previously added is completely dissolved. 
         [0030]    In the case of the discharge treatment device  200  being installed for use with a septic system, the discharge treatment device  200  can work with all solid versions of septic chemicals, bio-enzymes, and micro-organisms available in the marketplace, including, but not limited to, REX-BAC-T® Bacteria Blocks, RID-X® Septic System Treatment, and BIO-ACTIVE® Septic Tank Treatment. In addition to introducing septic chemicals and/or composting aids, the discharge treatment device  200  may also be used to introduce drain cleaning chemicals, root killers, and scents into the discharge stream  202 . The discharge treatment device  200  can hold all forms of solid pellets  214 , such as solid pellets  214  in stick form, gel form, and powder form. In some aspects of the disclosure, the discharge treatment device  200  may hold additives in liquid form. Further, the discharge treatment device  200  may include an injection mechanism, such as an electrically operated pump, to inject liquid into the discharge stream. For example, the electrically operated pump may include a battery operated pump to inject liquid into the discharge stream. 
         [0031]    Referring to  FIGS. 3 and 4 , the discharge treatment device  200  includes an entry section  222 , an exit section  224 , and a holding section  226  between the entry section  222  and the exit section  224 . The entry section  222  has at least one internal cavity enclosed by the wall of the entry section  222 . The exit section  224  has at least one internal cavity enclosed by the wall of the exit section  224 . The holding section  226  has at least one internal cavity enclosed by the wall of the holding section  226 . The internal cavity of the entry section  222 , the internal cavity of the exit section  224 , and the internal cavity of the holding section  226  are connected, allowing the discharge stream  202  from the food waste disposer in a direction “C” to pass from the entry section  222  through the holding section  226  to the exit section  224 . 
         [0032]      FIGS. 3 and 4  illustrate one configuration of the entry section  222 , the exit section  224 , and the holding section  226  with the entry section  222  being at approximately a right angle to both the exit section  224  and the holding section  226  and the holding section  226  being collinear with the exit section  224 . It is understood, however, that other configurations of the entry section  222 , the exit section  224 , and the holding section  226  are possible and within the scope of the present disclosure. For example, the entry section  222  and the exit section  224  may be at an obtuse angle and the entry section  222  and the holding section  226  may be at an acute angle. 
         [0033]    The diameter of the entry section  222  and the diameter of the exit section  224  may be approximately the same while the diameter of the holding section  226  may be smaller than the diameter of the entry section  222  and the diameter of the exit section  224  as shown. Alternatively, the diameter of the entry section  222  and the diameter of the exit section  224  may be different depending on the required flow rate and the desired pellet dissolving rate. The entry section  222  is connected to a tail pipe of the food waste disposer  204  and the exit section  224  is connected to a drain pipe. 
         [0034]    The holding section  226  has an exterior portion  228  and an interior portion  230 . The exterior portion  228  has at least one internal cavity enclosed by the wall of the exterior portion  228 . The interior portion  230  has at least one internal cavity enclosed by the wall of the interior portion  230 . The internal cavity of the exterior portion  228  and the internal cavity of the interior portion  230  are connected. The interior portion  230  and the exterior portion  228  hold at least one pellet of additives in the internal cavity of the interior portion  230  and the internal cavity of the exterior portion  228 . The interior portion  230  and the exterior portion  228  are connected through their internal cavities, allowing the at least one pellet of additives to enter the interior portion  230  from the exterior portion  228 . The exterior portion  228  has an exterior opening  232  for replenishing the additives as necessary, such as when a pellet previously added to the discharge treatment device  200  is completely dissolved. The exterior opening  232  of the exterior portion  228  is optionally covered by an exterior cap  234  to prevent spillage of the discharge stream  202  from the food waste disposer out of the discharge treatment device  200 . 
         [0035]    The exterior portion  228  and the interior portion  230  of the holding section  226  may have different lengths as shown. In some aspects of the present disclosure, the exterior portion  228  and the interior portion  230  may have the same length. The exterior portion  228  and the interior portion  230  may have the same length as shown. In some aspects of the present disclosure, the exterior portion  228  and the interior portion  230  have different lengths. The exterior portion  228  and the interior portion  230  may be tubular in shape as shown. In some aspects of the present disclosure, the exterior portion  228  and the interior portion  230  may have other shapes such as cubical or irregular shapes. In some aspects of the present disclosure, the exterior portion  228  may not be visible because the exterior cap  234  may completely enclose the exterior portion  228 . 
         [0036]      FIG. 4  shows a cut-away view of the discharge treatment device  200  of  FIG. 3  taken along line  1 - 1  of  FIG. 3 . The interior portion  230  optionally has a bottom member  236  that holds the at least one pellet. The discharge stream  202  from the waste disposer in a direction “C” may enter the interior portion  230  of the holding section  226  through at least one interior opening  238  on the interior portion  230 .  FIG. 4 , for example, shows two of the interior openings  238 . The at least one interior opening  238  may be, but is not limited to, a slot, a hole, a matrix, a filter, a permeable surface, a porous surface, a screen, and/or any other suitable surface permeable to water. The number of interior openings  238  and the type interior openings  238  may be based on the required flow rate and the desired pellet dissolving rate. 
         [0037]    After dissolving part of the at least one pellet of additives, the mixture  220  of the discharge stream  202  and the additives exits the holding section  226  through at least one bottom opening  240  on the bottom member  236  into a drain pipe in a direction “D.”  FIG. 4 , for example, shows three bottom openings  240 . The at least one bottom opening  240  may be, but is not limited to, a slot, a hole, a matrix, a filter, a permeable surface, a porous surface, a screen, and/or any other suitable surface permeable to water. The number of bottom openings  240  and the type of bottom openings  240  may be based on the required flow rate and the desired pellet dissolving rate. 
         [0038]    To secure the exterior cap  234  to the holding section  226 , the exterior portion  228  optionally has an externally threaded cylindrical portion  242  formed on it close to the exterior opening  232 . The exterior cap  234  optionally may have an internally threaded cylindrical part  244  formed on it near a cap opening  246  for screwing onto the threaded cylindrical part of the exterior portion  228 . Other mechanisms of securing the exterior cap  234  to the exterior portion  228  include the use screws with bolts, clamps, twist ties, cable ties, hooks, pins, and other suitable fastening mechanisms. 
         [0039]      FIG. 5  shows a cross-sectional view of a discharge treatment device  200 . In  FIG. 5 , for example, the entry section  222  slopes downward into the holding section  226  and exit section  224 , as opposed to the exterior wall of the entry section meeting the exterior wall of the holding section  226  at a right angle, as shown in  FIGS. 3 and 4 , for example. 
         [0040]    Referring to  FIGS. 3 ,  4 , and  5 , an inlet of the entry section  222  of the discharge treatment device  200  may be connected to a discharge outlet of a food waste disposer directly by a plumbing nut (not shown). Other exemplary ways to connect a food waste disposer to the discharge treatment device  200  are recited, for example, in U.S. Pat. No. 6,007,006 (Engel et al.), which is incorporated herein by reference. Alternatively, the inlet of the entry section  222  of the discharge treatment device  200  may be connected to a tailpipe that is connected to a food waste disposer by plumbing connection methods such as the use of fasteners, threaded pipe, solvent welding, soldering, brazing, welding, compression fittings, flare fittings, flange fittings, mechanical fittings, grooved pipe fittings, and crimped or pressed fittings. Alternatively, the entry section  222  of the discharge treatment device  200  may be connected to a sink by plumbing connection methods such as the use of fasteners, threaded pipe, solvent welding, soldering, brazing, welding, compression fittings, flare fittings, flange fittings, mechanical fittings, grooved pipe fittings, and crimped or pressed fittings. 
         [0041]    The exit section  224  of the discharge treatment device  200  may be connected to a drain pipe by plumbing connection methods such as the use of fasteners, threaded pipe, solvent welding, soldering, brazing, welding, compression fittings, flare fittings, flange fittings, mechanical fittings, grooved pipe fittings, and crimped or pressed fittings. 
         [0042]    The discharge treatment device  200  may be composed of metallic materials such as aluminum, copper, and stainless steel. The discharge treatment device  200  may be formed by powdered metal methods. Alternatively, the discharge treatment device  200  may be made of a polymeric material or a composite material. The discharge treatment device  200  may be formed by injection molding methods such as insert plastic injection molding, metal injection molding, or by casting methods such as die-casting or investment casting. The discharge treatment device  200  may be made of a molding process from a polymeric material such as, but not limited to, polypropylene, polyamide, or the like. Alternatively, the discharge treatment device  200  may be made partially from translucent and transparent materials to enable a user to visually determine the amount of the pellet  214  remaining. The discharge treatment device  200  may be made entirely of translucent and transparent materials. 
         [0043]      FIGS. 6 ,  7 ,  8 , and  9  show further aspects of the present disclosure.  FIG. 6  demonstrates one configuration of the entry section  222 , the exit section  224 , and the holding section  226  with the entry section  222  being at approximately right angle to both the exit section  224  and the holding section  226 , while the exit section  224  and the holding section  226  are at an obtuse angle. The diameter of the entry section  222  and the diameter of the exit section  224  may be approximately the same while the diameter of the holding section  226  may be smaller than the diameter of the entry section  222  and the diameter of the exit section  224  as shown. 
         [0044]    The discharge stream  202  from the waste disposer may enter the interior portion  230  of the holding section  226  in a direction “C” through the at least one interior opening  238  on the interior portion  230 .  FIGS. 6 and 7 , for example, show four interior openings  238 . After dissolving at least part of the pellet  214  of additives, the mixture  220  of the discharge stream  202  and the additives exits the holding section  226  through at least one bottom opening  330  on the bottom member  336  and flows into the drain pipe in a direction “D,” as shown in  FIGS. 8 and 9 . The number and type of interior openings  238  and bottom openings  330  are chosen based on the required flow rate and the desired pellet dissolving rate. Alternatively, the interior portion  230  may not have any bottom member or bottom opening. 
         [0045]    Referring to  FIG. 7 , to use the discharge treatment device  200 , a user may insert the at least one pellet  214  of additives into the holding section  226  through the exterior opening  232  of the exterior portion  228 . After adding the at least one pellet  214  to the holding member, the user may screw the exterior cap  234  onto the externally threaded cylindrical portion  242  of the exterior portion  228  to secure the exterior cap  234  to the holding section  226 . 
         [0046]    The discharge treatment device  200  with aspects of the present disclosure has fewer parts, resulting in lower cost. Additionally, because the discharge treatment device  200  may be retrofitted to the food waste disposer  204 , the initial cost of installing the discharge treatment device  200  to the food waste disposer  204  is lower. Because the amount of chemicals dissolved is proportional to the amount of the discharge stream from the food waste disposer, the discharge treatment device  200  may introduce the appropriate amounts of additives, thus lowering the operating cost. Introducing the appropriate amounts of additives maximizes the effectiveness, minimizes waste, and lessens the environmental impact of the additives. The operation of the discharge treatment device  200  does not require electricity, further lowering the operating cost. Furthermore, this passive introduction of additives avoids the need of pouring them down the drain or directly into, for example, a septic tank or compost collection tank. A user may simply open the faucet and run water into the food waste disposer  204  to introduce additives into the septic system or composting system. 
         [0047]    Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the orientation of the figures, which show the typical orientation of the discharge treatment device  200  connected to the food waste disposer  204 . 
         [0048]    The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
