A cooking appliance including a temperature sensing system having an upper housing having a first heating surface and a lower housing having a second heating surface includes a temperature sensing probe, a control panel and a control unit in electrical communication with the temperature sensing probe and the control panel. The temperature sensing probe is removably received by the upper housing and extends through the first heating surface. The control panel has one or more input buttons for allowing a user to select at least one input parameter including a desired internal temperature of a food item.

1. A cooking appliance, said cooking appliance comprising: an upper housing having a first heating surface selectively contacting a food item,a lower housing having a second heating surface selectively contacting said food item,a control panel having one or more input means for allowing a user to select at least one input parameter, said at least one input parameter including a desired internal temperature of said food item;a control unit integrated with said cooking appliance;a temperature sensing system, said temperature sensing system comprising a temperature sensing probe, said temperature sensing probe being removably received by said upper housing and selectively extending through said first heating surface;wherein said control unit being in electrical communication with said temperature sensing probe and said control panel, said control unit selectively operating said cooking appliance in dependence upon data from said temperature sensing probe;wherein said temperature sensing probe includes a rotatable knob and a piercing shaft having a temperature sensor, said piercing shaft being extendable from a first position, in which said piercing shaft is substantially contained within said upper housing, to a second position, in which said piercing shaft protrudes from said upper housing to pierce said food item;wherein rotation of said rotatable knob effects the extension of said piercing shaft from said first position to said second position;wherein said temperature sensing probe further includes a guide cylinder and a probe housing having at least one protrusion extending from said housing;wherein said at least one protrusion is received in an angled slot formed in said guide cylinder and a substantially vertical groove formed in said rotatable knob; andwherein said guide cylinder is housed within said rotatable knob;wherein said cooking appliance further comprising an electrical pathway connecting said control unit and said temperature sensing probe when said temperature sensing probe is received by said upper housing;wherein said electrical pathway comprising at least one terminal in electrical communication with a temperature sensor in said temperature sensing probe, and said at least one terminal is in electrical communication with a conductive strip in said guide cylinder, and said conductive strip is in electrical communication with said control unit. 2. The cooking appliance of claim 1, wherein: said control unit is configured to control operation of at least one of said first and said second heating surfaces in dependence upon said at least one input parameter and an internal temperature of said food item detected by said temperature sensing probe. 3. The cooking appliance of claim 1, further comprising: a locking mechanism for selectively locking said temperature sensing probe to said upper housing. 4. The cooking appliance of claim 3, wherein: said locking mechanism includes a lock button, a substantially U-shaped actuating member and a pair of opposed sliders, said sliders being configured to selectively engage said temperature sensing probe to lock said probe to said upper housing by engaging a retaining plate of said probe. 5. The cooking appliance of claim 1, wherein: said control unit is configured to deactivate said first and second heating surfaces when said desired internal temperature is detected by said temperature sensing probe. 6. The cooking appliance of claim 1, wherein: said control unit is configured to generate an audible alert when said desired internal temperature is detected by said temperature sensing probe. 7. A cooking appliance, comprising: an upper housing having an upper heating surface which selectively contacts a food item and a lower housing having a lower heating surface which selectively contacts said food item;a temperature sensing probe received by said upper housing and selectively extending through said upper heating surface;a control panel having one or more input means for allowing a user to select at least one input parameter, said at least one input parameter including a desired internal temperature or doneness of said food item; anda control unit in electrical communication with said temperature sensing probe and said control panel,wherein said temperature sensing probe comprising a rotatable knob and a piercing shaft, said piercing shaft is selectively movable between a first position, in which said extends through said upper heating surface, and a second position, in which said piercing shaft is retracted substantially into said rotatable knob and does not extend through said upper heating surface,wherein rotation of said rotatable knob effects the extension of said piercing shaft from said first position to said second position;wherein said temperature sensing probe further includes a guide cylinder and a probe housing having at least one protrusion extending from said housing;wherein said at least one protrusion is received in an angled slot formed in said guide cylinder and a substantially vertical groove formed in said rotatable knob; andwherein said guide cylinder is housed within said rotatable knob;wherein said cooking appliance further comprising an electrical pathway connecting said control unit and said temperature sensing probe when said temperature sensing probe is received by said upper housing;wherein said electrical pathway comprising at least one terminal in electrical communication with a temperature sensor in said temperature sensing probe, and said at least one terminal is in electrical communication with a conductive strip in said guide cylinder, and said conductive strip is in electrical communication with said control unit. 8. The cooking appliance of claim 7, wherein: said temperature sensing probe is selectively removable from said upper housing. 9. The cooking appliance of claim 7, further comprising: a locking mechanism for selectively locking said temperature sensing probe to said upper housing. 10. The cooking appliance of claim 9, wherein: said locking mechanism includes a lock button, a substantially U-shaped actuating member and a pair of opposed sliders, said sliders being configured to selectively engage said temperature sensing probe to lock said probe to said upper housing by engaging a retaining plate of said probe. 11. The cooking appliance of claim 7, wherein: said control unit is configured to control operation of at least one of said first and said second heating surfaces in dependence upon said at least one input parameter and an internal temperature of said food item detected by said temperature sensing probe. 12. The cooking appliance of claim 11, wherein: said control unit is configured to deactivate said first and second heating surfaces when said desired internal temperature or doneness is detected by said temperature sensing probe.
