Green sink

Abstract

It is an object of this invention to provide a method of maintaining a constant or variable water temperature in kitchen sinks, bathroom sinks, bathtubs, baby tubs, pet dishes (stop from freezing in the winter) and a wide variety of liquid containers such as cattle and horse water troughs, banquet food warmers (to replace sterno heat source) commercial sinks an portable liquid containers. For example, keeping the water warm or hot enough to do more dishes without draining the sink of cold water in order to replace it with warm or hot water, could potentially save millions of gallons of water across the country every day.

1 . A method of manufacturing liquid receptacles with heating elements for controlling liquid temperatures within said liquid receptacles comprising the steps of:
 a. imbedding a heating element in a shell of said liquid receptacle,;   b. mounting a control panel in a conveniently accessible location;   c. connecting an electrical logic circuit to said control panel,   d. attaching an appropriate power supply to said heating element;   e. attaching an appropriate power source to said power supply and.   f. attaching an appropriate power source to said electrical logic circuit.   
     
     
         2 . The method of  claim 1  wherein said control panel comprises the steps of:
 a. mounting an on/off switch on said control panel;   b. mounting a temperature control on said control panel;   c. mounting a heat timer on said control panel and   d. mounting a reset switch on said control panel.   
     
     
         3 . The method of  claim 2  wherein said control panel further comprises the steps of:
 a. programming of an electrical logic circuit comprising the steps of:
 1. initializing the electrical logic circuit with a system on/off switch 
 2. supplying a heating element with a heating element power source, 
 3. controlling said heating element power source with a heating element on/off device, 
 4. controlling said heating element on/off device by a heat timer, 
 5. adjusting said heat timer to a user selected time, 
 6. setting a temperature control to a user selected temperature, 
 7. monitoring the selected temperature by use of an appropriate temperature sensor, 
 8. feeding back information from said temperature sensor to said temperature control, 
 10. energizing an over-temperature relay should said temperature sensor become activated, 
 11. energizing an over-temperature warning should said temperature sensor become activated, 
 12. turning off said heating element via said heating element on/off device with signal from said over-temperature relay and 
 13. turning off the on/off switch with a signal from said over-temperature relay, 
   b. re-initializing said electrical logic circuit after programmed shut-down comprising the further steps of;
 1. re-setting said over-temperature relay and said over-temperature warning by depressing said relay reset and, 
 2. re-applying the logic circuit power source by re-setting said on/off switch via the re-setting of said over-temperature relay 
   
     
     
         4 . A method of modifying liquid receptacles with heating elements for controlling liquid temperatures within said liquid receptacles comprising the steps of:
 a. applying a heating element to one or multiple surfaces of said heating receptacle,   b. mounting a control panel in a conveniently accessible location;   c. connecting an electrical logic circuit to said control panel,   d. attaching an appropriate power supply to said heating element;   e. attaching an appropriate power source to said power supply and   f. attaching an appropriate power source to said electrical logic circuit.   
     
     
         5 . The method of  claim 4  wherein said control panel comprises the steps of:
 a. mounting an on/off switch on said control panel;   b. mounting a temperature control on said control panel;   c. mounting a heat timer on said control panel and   d. mounting a reset switch on said control panel.   
     
     
         6 . The method of  claim 5  wherein said control panel further comprises the steps of:
 a. programming of an electrical logic circuit comprising the steps of:
 1. initializing the electrical logic circuit with a system on/off switch 
 2. supplying a heating element with a heating element power source, 
 3. controlling said heating element power source with a heating element on/off device, 
 4. controlling said heating element on/off device by a heat timer, 
 5. adjusting said heat timer to a user selected time, 
 6. setting a temperature control to a user selected temperature, 
 7. monitoring the selected temperature by use of an appropriate temperature sensor, 
 8. feeding back information from said temperature sensor to said temperature control, 
 10. energizing an over-temperature relay should said temperature sensor become activated, 
 11. energizing an over-temperature warning should said temperature sensor become activated, 
 12. turning off said heating element via said heating element on/off device with signal from said over-temperature relay and 
 13. turning off the on/off switch with a signal from said over-temperature relay, 
   b. re-initializing said electrical logic circuit after programmed shut-down comprising the further steps of;
 1. re-setting said over-temperature relay and said over-temperature warning by depressing said relay reset and, 
 2. re-applying the logic circuit power source by re-setting said on/off switch via the re-setting of said over-temperature relay
