         [0034]    As shown in  FIGS. 1-26 , generally the system  30  comprises a well  33  having a cavity  34 . Well  33  is mounted in relationship to a top housing  36 . The housing  36  is shown resting above a counter  39 . Toward its lower portion, the well  33  has an outlet opening which is associated with a drain plug fitting  42 . The fitting  42  is associated with a drain handle  45 . The fitting  42  also is in liquid flow association with an overflow tube  48  which has an upper end  49 . The handle  45  can be hand operated to lift the drain fitting  42  out of well  33 , and in conjunction therewith to remove the overflow tube  48 . 
         [0035]    The system  30  further comprises an insert or support  51 , shown located toward the bottom of well  33 . The support  51  acts to provide support for a food utensil such as a dipper, scoop, spoon, ladle or fork, for example, such as the scoop  52  shown in  FIGS. 12 and 21 . The system  30  further comprises a heating subsystem  54  which includes a heating element  57 , heating plate  58  and electrical circuitry. element  57  is positioned relative to the well  33  so that heating subsystem  54  can be operated to heat the element  57 . Element  57  heats heat transfer plate  58 , which is preferably made of aluminum, and which transfer heat to the well  33  to thereby heat liquid within the well cavity  34 . plate  58  also helps to mount element  57 . 
         [0036]    The system  30  additionally includes a lower housing  59  associated with the well  33 . housing  59  can house the heating element  57 , plate  58 , as well as electrical wiring, a drain tube  61 , and mounting components for element  57 . The drain tube  61  can be positioned to be in fluid flow connection with the fitting  42 . A control housing  62  can be mounted with housing  59 , to act as a power inlet box to receive cords, wires and to house control systems for temperature and water flow that extend to electrical switches and to the heating element  57 . 
         [0037]    The system  30  further includes one or more faucet assemblies  63  that can discharge fluid into the well  33 , one such faucet assembly  63  being shown in  FIGS. 1-3 ,  17 - 19 ,  21 - 22 . The faucet assembly  63  comprises a housing  64  with an operational component such as a handle or knob  66  illustrated, connected to a valve within the assembly  63  as known in the art, to block, or allow controlled liquid flow through a faucet nozzle  69 . Faucet assembly  63  can comprise a flow tube or pipe  72  and a fitting  74  that can be connected to a water supply source. The faucet assembly  63  can be mounted in association with the counter  39 . The faucet nozzle  69  is positioned so that water or other liquid can be discharged there from into the well cavity  34 . 
         [0038]    The system  30  can also comprise electrical circuitry and control valves such as solenoid valve fittings discussed hereafter and shown in  FIGS. 17-19 , to provide for draining the contents well cavity  34  for a predetermined amount of time and filling the well cavity  34  with water from the faucet assembly  63  for a predetermined amount of time. 
         [0039]    The arrangement of the components of system  30  is such that the heating subassembly  54  can be operated to heat fluids, such as water, located within well cavity  34  to a temperature of at least 135° F., and will allow the system to be operated for extended periods of time, such as ten to thirty hours, at temperatures in the range of 135° F. to about 160° F. Food utensils can be placed in the well cavity  34  to rest upon support  51  to provide for sanitary location of the utensil while it is not being used. 
         [0040]    More Detailed Description 
         [0041]    Now, providing a more detailed description of system  30 . The well  33  can be generally a container of a variety of shapes such as without limitation, a rectangular prism, triangular prism, octagonal prism, hexagonal prism, pentagonal prism, or cylindrical as shown in the drawings. Well  33  can have an outer wall such as the illustrated generally cylindrical vertical wall  83 . Well wall  83  is shown to depend downwardly into a rounded area  86  which extends into a generally horizontal bottom wall  89 . At the upper end of well  33 , the wall  83  extends into an outwardly directed flange  92 , shown curved with a concave underside and having an outer end  93  which can rest upon the upper surface  94  of the upper wall  95  of top housing  36 . The upper end of the well  33  can be secured to the housing  36 , such as by placing a bead of silicone adhesive within the concave portion of the upper well flange  92 , and then extending the well  83  through the top of the opening through housing  36  with the underside of flange  92  facing the top surface  94  of housing upper wall  95  and held thereto so that the said adhesive within flange  92  bonds with top housing surface  94 . This allows an integral bonding of the housing  36  with the well  33  so that those two members can be handled together during installation. Other means of bonding the well  33  with housing wall  95  can be used, such as by welding, brazing, or with threaded studs and nuts. 
         [0042]    The drain fitting  42  is specifically shown to have a larger generally cylindrical upper section  99 . As shown more clearly in  FIGS. 4-9 , section  99  depends downwardly into a lower generally cylindrical section  102 , with a generally horizontal annular shoulder  105  located about the lower edge of bottom section  99 . The fitting  42  is positioned relative to well  33  so that the annular shoulder  105  rests against the upper surface  106  of the well bottom wall  89  to be supported thereby. In that position, the fitting lower section  102  extends through a generally cylindrical drain opening in the well bottom wall  89 . The pressure of shoulder  105  against surface  106  seals off liquid from flowing from the well cavity  34  to pass around the outside of fitting  42  and outside of drain tube  61 . 
         [0043]    Fitting  42  has a generally cylindrical cavity  110  that has its lower end opening  111  through the bottom of lower fitting section  102 . The cavity  110  extends upwardly to within the upper fitting section  99 . The upper end of cavity  110  is closed by the upper wall  112  of fitting section  99 . A transverse bore  113  extends generally horizontally through a part of the wall of upper fitting section  99  to open into fitting cavity  110 . the lower end section  114  of overflow tube  48  is telescopically received for a snug fit within transverse bore  113  and can be secured therein as by welding, so that fluid can flow through overflow tube  48  though transverse bore  113  and through cavity  110  thence through drain tube  61  to a general drainage pipe or tube (not shown). The lower fitting section  102  has an outer cylindrical surface  115  with an angular groove  116  that can receive a washer  116   a.    
         [0044]    The drain tube  61  is illustrated as generally cylindrical, but it can have other shapes such as rectangular prism, octagonal prism hexagonal prism or pentagonal prism. As shown, the outer cylindrical surface  115  of fitting lower section  102  is telescopically snugly received with drain tube  61  to allow fluid flow from the fitting cavity  110  into the tube  61 . The tube  61  can be secured as by brazing to the lower well wall  89 . The lower exterior of the drain tube  61  can be threaded if desired to accommodate a screw fitting with drainage hose fitting, or with, for example, a solenoid controlled valve fitting described below as to  FIGS. 17-19 . 
         [0045]    A pair of mounting flanges  117  extends upwardly from the top of upper fitting section  99 . The lower section  118  of drain handle  45  extends between the two flanges  117 , and is spaced from the flanges  117 . A pin  121  extends through the flanges  117  and through the handle lower section  118 , so that the handle lower section  118  pivots freely between flanges  117  about pin  121 . 
         [0046]    The drain handle  45  can have a shape such as shown in the drawings whereby it extends from its lower section  118  connected to the flanges  117  to bend into curved section  130 , and thence extends generally upward into a section  133 . section  133  thence bends into a curved section  136  that extends into end segment  139 . end segment  139  can rest against the upper surface  94  of top housing  36 . 
         [0047]    The overflow tube  48  extends from its lower end  114  into a curved segment  140  which extends into a generally vertical segment  141 . The upper end  49  of tube  48  is located beneath the upper edge of the well  33 , i.e., beneath the top surface of the well flange  92 . Preferably the overflow tube is located about 0.5 inches to about 1.5 inches beneath the top edge of well  33 , although different distances may be desired. Thus, from the illustration shown, when a level of water or other liquid within well cavity  34  rises above the upper end  49  of overflow tube  48 , fluid within well cavity  34  will descend to flow through the overflow tube  48 , through the drain fitting  42  and thence downwardly through drain tube  61  as described. 
         [0048]    The utensil support  51  is shaped to have an upper platform section  147  upon which one or more utensils can rest. Support  51  has a structure that can depend downwardly from the platform section  147  to fit about the overflow tube  48  and drain handle  45 , so that the lower end of the support  51  can rest generally upon or otherwise be supported by the well bottom wall  89 . As illustrated. The upper support platform  147  has a generally octagonal configuration. platform  147  has an opening  152  sized to allow the drain fitting  42 , as well as the lower end section of drain handle  45 , to pass there-through when the handle  45  is lifted upward to remove the fitting  42 . platform  147  also has an opening  155  that joins opening  152 . Opening  155  is sized to allow overflow tube  48  and part of drain handle  45  to pass there-through. As shown, opening  155  extends through the outer edge of platform wall  147 . Along each of four alternating sides of the octagonal support platform  147  depend generally vertical legs  161 . Legs  161  are shown as flange shaped with their lower ends  163  resting upon the upper surface  106  of well lower wall  89 . 
         [0049]    The top housing  36  has a depending curtain wall  170  descending about the perimeter of upper housing top wall  95 . At the lower edge of curtain wall  170  are inwardly extending flat feet sections  173 . The bottoms of feet  173  can rest upon the upper surface of the counter  39  to supported housing  36  thereon. As shown in the drawings. The top housing  36  is hexagonal, with one part having a general trapezoid configuration facing the front of the counter  39  toward the operator, and the other unitary part having a generally rectangular configuration located near the back edge of the counter  39 . The top housing upper wall  95  has a generally circular bore  182  which can be aligned with a generally cylindrical passageway extending through the surface of counter  39 . Thus, the system  30  provides support for the well  33  by the well  33  being supported through its contact of annular flange  92  upon the top housing wall surface  94  and the support of the top housing  36  upon counter  39  as described. The housing  36  can have an electrical switch  174  mounted thereto. switch  174  can be a toggle switch having an “on” position whereby an electrical circuit is completed through the heating element  57  to heat fluid within the well cavity  34 . Switch  174  also has an “off” position in which the circuit through heating element  57  is open so that the element  57  is not heated. 
         [0050]    The well  33  can be secured to the counter such as by mounting brackets  180  as shown in  FIG. 14 . The mounting brackets have generally horizontal flanges  183  that can be secured to the underside of the horizontal wall  186  of the counter  39 . The brackets  180  also have generally vertically extending flanges  187  which extend along the side of the outer surface of the well wall  83 . A stud  188  is welded to the well wall  83 , and stud  188  passes through an opening in each vertical flange  187 , and thence stud  188  passes through a nut positioned against the outer surface of vertical flange  187  to thus secure well  33  to the counter  39 . At both outer edges of vertical flange  87  are outwardly extending wing flanges  189 . 
         [0051]    Housing  59  includes the top heat transfer plate  58  and a holding plate  195  that is mounted with threaded studs  198  attached to the bottom of the well  33  and secured with nuts  199  that abut the underside of plate  195  to support plate  195  a predetermined distance beneath heat plate  58 . heating plate  58  is preferably of aluminum. The heating element  57  can have a generally arcuate shape. The heating element  57  rests upon the upper surface of holding plate  195  so that the top of the heating element  57  abuts the bottom surface of heat transfer plate  58  to be held there between to heat it and thereby heat the bottom well wall  89  and the contents of well cavity  34 . The lower housing  59  further comprises a peripheral casing  202 . Casing  202  is shown isolated in  FIGS. 15-16 .  FIG. 16  shows the casing  202  layout in flat sheet metal preformed configuration prior to shaping it in the form of  FIG. 16 . The casing  202  in  FIG. 15  as formed generally has an octagonal base wall  204  having eight side edges, from which extend at generally right angles a plurality of corresponding walls  206 , yielding an octagonal shape for the casing  202 . The casing base wall  204  has a generally centrally located circular opening  207  through which the drain tube  61  can extend. base  204  also has a pair of smaller circular openings  208  through which the studs  198  can pass and be secured by nuts  210  on the underside of base wall  204 . One of the octagonal side walls  206  can have a circular opening  211  to receive electrical wiring from the control housing  62 . 
         [0052]    The heating subsystem  54  can also include a thermostat  213  in electrical connection with the electrical circuitry and heating element  57 , and in sensing contact with the well bottom wall  89 , to allow maintaining the temperature of the well cavity contents at a selected temperature. 
         [0053]    The structure of the drain fitting  42  has been illustrated with the upper section  99  and lower section  102  preferably being unitary. Alternatively they can be integral with one another. The flanges  117  are preferably unitary with fitting section  99 , or alternatively can be integral with each other. Drain tube  75  is preferably integral with the upper wall of the bottom housing  59 . The heating element  57  preferably has an arcuate configuration as shown, but could be of different shapes, such as serpentine, U-shaped or spiral. If desired, the heating plate  58  can have a conforming recess on its underside shape to receive the heating element  57 . Further, element  57  and heating plate  58  can be integral and one piece. Element and holding plate  195  can be of one piece, and be recessed. 
         [0054]    Various other modifications of this design as described and shown could be made. For example, the support  51 , drain handle  45 , overflow tube  48  and fitting  42  can be shaped and arranged so that both the handle  45  and overflow tube  48  extend generally vertically from the fitting  42 . the overflow tube lower end could extend through the top of fitting section  99  to connect the tube flow to the cavity  110 . In such case, the mounting of the handle  45  to a flange or flanges secured to the fitting section  42  can be offset. With such an arrangement the drain tube and the handle could also be curved toward their bottoms to come in at different angles or directions to connect with the drain fitting  42 . In such an example, the support  51  can have centrally located opening and need not have an opening extend to the outer edge of the support platform  147 . The platform  147  can also be perforated with a plurality of holes such as illustrated in  FIG. 12 . 
         [0055]    The faucet control is illustrated with a rotatable knob, but could be by other known means such as by lever handle or push button. The location of the faucet assembly  63  can vary, with  FIG. 9A  showing two possible locations. 
         [0056]    In installation and operation, the opening  250  in counter platform wall  171  is sized and shaped to allow accommodate passage there through of the well  33 , the lower housing  59  and the control housing  62 . For example, the counter hole can be generally circular and about 6″ in diameter to accommodate a well having a diameter from about 4.8″ to about 5.0″. An assembly  253  of the top housing  36 , well  33 , lower housing  59  and control housing  62  can be positioned so that the central vertical axis of well  33  is tilted at an angle relative to the counter platform  171  to pass lower housing  59 , control housing  62  and the lower part of well  33  through the counter hole  250 . Once lower housing  59 , control housing  62  and the lower part of well  33  clear through hole  250 , the axis of well  33  is tilted to a generally vertical position to slide the well wall  83  through the platform opening  250  until the top housing feet  173  rest upon the top surface of counter platform  171 . Electrical connections are made to control housing  62  to provide electrical power to assembly  30 . 
         [0057]    The lower housing  59  housing heating element  57  is positioned relative to the well  33  to heat liquid in the well cavity  37  to a temperature of at least 135 F.° as described. 
         [0058]    The drain fitting  42  with drain handle  45 , and overflow tube  48  are placed so fitting  42  is located as shown in  FIG. 1 . The faucet assembly  63  is installed to be connected to a supply pipe so that water can flow there from into the well cavity  34  up to the level of the overflow tube upper end  49 . When it is desired to discharge the contents of well cavity  34 , the drain handle  45  can be grasped to remove the drain fitting  42  to allow liquid within the well cavity  34  to flow through the drain tube  61 . 
         [0059]    The utensil support  51  is placed within the cavity  34  of well  33  so that the support  51  is supported by the structure of well  33 , and so that the support  51  is placed within the cavity  34  of the well  33  so that the platform  147  is positioned to support a food utensil, with the structure of support  51  fitting about the drain fitting  42 , the overflow tube  140  and the drain handle  45 , such as previously described. 
         [0060]    As shown in the embodiment of  FIGS. 17-19 , the system  30 ′ can also be provided with a valve fitting  220  having a flow path there through controlled by a solenoid. fitting  220  is mounted toward the bottom of, and in fluid flow connection with, drain tube  61 ′, such as the lower exterior of drain tube  61 ′ being threaded to be received with a threaded inlet bore of the fluid flow path of the valve fitting  220 . Alternatively, the interior of drain tube  61 ′ can be threaded at its lower end to receive the externally threaded male end of a solenoid valve fitting. With this embodiment the drain plug fitting  42 , handle  45  and overflow tube  48  are not present. The solenoid controlled valve of fitting  220  can be actuated through a momentary switch  222  to open the valve to allow fluid to pass through fitting  220  to thereby drain the well cavity  34 ′. A timer and electrical and electronic circuitry can be provided and can be located in part in the control housing  62 ′ and connected in conjunction with the switch  222  to hold the solenoid valve  220  open for a predetermined amount of time for well drainage. Alternatively, the momentary switch  222  and circuitry can be such as to have the valve of fitting  220  to remain open as long as the button of switch  222  is pressed. 
         [0061]    An automatic filling operation can also be performed through electrical and electronic circuitry connected with a solenoid controlled valve fitting  230 . Fitting  230  has a flow path there through controlled by a solenoid. Fitting  230  is mounted toward the bottom of, and in fluid flow connection with, faucet assembly  63 ′. With the faucet knob  66 ′ rotated to place the valve of faucet assembly  63 ′ in an “open” position, the solenoid controlled valve of fitting  230  can be actuated through a momentary switch  233  to open the valve of fitting  230  to allow fluid to pass through fitting  230  to thereby flow through the faucet assembly  63 ′, thence discharged through faucet nozzle  69 ′ in to well cavity  34 ′. A timer can be provided in the circuitry, and located such as in the control housing  62 ′ and connected in conjunction with the switch  233  to maintain the solenoid valve of fitting  230  open for a predetermined amount of time for pouring water through nozzle  69 ′ in to well cavity  34 ′. If the solenoid controlled fitting  230  is used, the faucet assembly  63 ′ can, if desired, be provided sans the manually controlled valve such as controlled by knob  66 ′, so that the only control of flow through the faucet assembly  63 ′ is by the solenoid controlled fitting  230 . 
         [0062]    The solenoid controlled valve fittings  220  and  230  can be those as are commercially available. One example of such fitting is STC Valve® model number 2P200-3/4 sold by Sizto Tech Corporation having an address of 892 Commercial Street, Palo Alto, Calif. 94303, USA. Another example of such fitting is Beta Valve brand solenoid valve model number 6115BC sold by Beta Valve System s Ltd., Park House Business Centre, Desborough Park Road, High Wycombe, Bucks HP12 3DJ, United Kingdom. 
         [0063]    The solenoid valve fitting  220  and its electrical circuitry as described can be operated in tandem with the solenoid controlled valve fitting  230  to drain and fill the well cavity  34 ′ in sequence. To drain and fill the well cavity  34 ′, the operator pushes the momentary switch  222  to open the solenoid controlled valve of fitting  220  for a predetermined amount of time to drain the well cavity  34 ′ through drain tube  61 . After that, the momentary switch  222  is released to close the valve of drain fitting  220 . Following that, the switch  233  can be activated to open the valve in fitting  230  so that water flows though faucet nozzle  69  to fill well cavity  34 ′ as described. 
         [0064]    The electrical circuitry and its timing controls can be provided so that rather than using two switches  222  and  233 , a single switch is used with electrical circuitry to automatically open and shut the values of solenoid valve fittings  220  and  230  to drain, then fill, well cavity  34 ′. The said switch, which can be located in the same position as switch  222  can be activated with its associated circuitry to open the solenoid controlled valve of fitting  230  to drain the well cavity  34 ′ for a preselected period of time. After passage of that preselected period of time, the electrical circuitry with timer acts with the solenoid of fitting  220  to close the valve of fitting  220 . Within a short period of time thereafter, such as preferably about 1 to about 8 seconds, the circuitry timing acts to open the valve of faucet solenoid fitting  230  to allow water to flow through fitting  230  through nozzle  69 ′ in to well cavity  34 ′ to a preselected level, such as just beneath the overflow tube top  49 . After that, the circuitry acts with the solenoid valve of fitting  230  to close the valve of fitting  230  to stop flow of water through fitting  230  and through nozzle  69 . 
         [0065]    Rather than having a single switch such as described, the electrical circuitry can be provided to begin the draining operation within a preselected amount of time following the filling of the well cavity  34 ′. The filling operation would then automatically follow the draining operation such as described above. Alternatively the commencement of the well draining operation can be programmed to be triggered to begin based on the level of food waste accumulation in the well cavity  34 ′. When that predetermined amount of waste accumulation is detected, such as by an electronic control that measures the resistivity of the water in the well cavity  34 ′, the circuitry commences the cycle by activating the solenoid of drain fitting  220  to open the valve of fitting  220  to drain the well cavity  34 ′. 
         [0066]    Changes can be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
