It is appreciated that the heater 60 may be positioned external to the chamber 40 as long as the heated air is directed into the interior of the chamber 40.
The chamber 40 includes one or more, and preferably two, circulation fans 63 mounted above the heater 60 within the directly heated space 51 of the chamber 40. The circulation fans 63 are secured above the heater 60 via a support 64. The circulation fans 63 generally blow directly upon or near the heater 60 and direct the air towards the perforated floor 47 to travel within the passageway 49 towards the indirectly heated space 52 and then rise (through the natural rising process of heated air) onto the object 12. The fans 63 continue to circulate the air within the chamber 40 by pulling air from near the ceiling 45 of the chamber 40 and directing the air towards the perforated floor 47.
The present invention also generally includes a plurality of internal temperature sensors 67 comprised of a probe structure to be inserted within the objects 12 to measure an internal temperature of the objects 12. The sensors 67 are generally comprised of thermistor sensors or thermo couples to measure temperature. The sensors 67 are preferably comprised of a substantially small diameter structure to leave minimal or no marks within the object 12.
Lead wires 68 are connected to the sensors 67 that are directed to one or more controllers 79 within the control room 70 or at another location to allow an operator to monitor the internal temperature of the objects 12 to ensure complete heating of the objects 12 both internally and externally. It is appreciated that the transmission of the data from the sensors 67 to the controller 79 may be accomplished in various manners.
It is also appreciated that the chamber 40 includes one or more ambient or external temperature sensors to record an air temperature external of the objects 12 within the chamber 40. The external temperature sensors (not shown) are generally positioned external to the objects 12 within the interior of the chamber 40, such as within the indirectly heated space 52 to accurately measure the temperature of the ambient air surrounding the object 12. It is appreciated that one or a plurality of external temperature sensors may be used and the external temperatures sensors may use various technologies to measure the ambient temperature.
E. Control Room.
The control room 70 is also generally located upon the frame 21 of the vehicle 20. The control room 70, in the preferred embodiment, is positioned forwardly of the chamber 40, wherein the front wall 42 defines a rear wall of the control room 70. The control room 70 also generally includes sidewalls 71 and a ceiling 75 to completely enclose the control room 70. The sidewalls 71 of the control room 70 and the sidewalls 71 of the chamber 40 are preferably substantially integral as viewed from outside of the vehicle 20. The ceiling 75 is also generally integral with the ceiling 45.
The control room 70 generally includes a door 73 including a handle 74 to access the interior of the control room 70 and one or more windows 72. The control room 70 may also include various vents, electrical outlets, and other mechanics or components to allow for the mechanical and electrical operation of the present invention. The control room 70 also generally includes one or more controllers 79 for recording and viewing temperature data of the chamber 40. The controller 79 may record temperature external and internal to the objects 12, along with heating time, heater 60 statistics, and various other types of data useful in determining the sanitization of the objects 12 within the chamber 40.
The controller 79 or various other transmission devices may also be connected to an external computer (e.g. laptop, etc.) for transferring the heating data thereto. The transferred heat data of the chamber 40 and objects 12 may be compiled and arranged for study of the effectiveness of the heater 60, determination of the sanitization of various parts of the object 12, proof to the customer of internally and externally heating the objects 12 for a specific timeframe 21, and for various other purposes.
F. Operation of Preferred Embodiment.
In use, the object 12 is positioned within the indirectly heated space 52 of the chamber 40. The internal temperature sensors 67 are then inserted within the object 12 at various locations and depths to thoroughly measure the internal temperature of the object 12. The rear door 43 are then closed to seal the chamber 40. The operator then enters the control room 70 and activates the heater 60, the circulation fans 63, and the controller 79.
Heat radiates outward from the heater 60 and the circulation fans 63 direct the heated air 14 to within the passageway 49, under the partition 50, and into the indirectly heated space 52 to contact the object 12 by rising out of the passageway 49. The heated air 14 continues to rise and is pulled towards the circulation fans 63, via the suctioning force of the rotating blades of the circulation fans 63. The heated air 14 continues to circulate throughout the interior of the chamber 40 thus evenly heating the object 12.
Both, the internal temperature of the object 12 and the external temperature of the air surrounding the object 12 are continually monitored via the controller 79 receiving data from the internal temperature sensors 67 and the external temperature sensors. The heater 60 continues to heat the interior of the chamber 40 until both of the internal temperature and the external temperature reaches a predetermined temperature and remains at that predetermined temperature which is known to terminate all insects, bugs, bacteria, etc. Once the desired heat temperature is reached both external and internal to the objects 12, the heater 60 may be turned off and the fans 63 allowed to continue to circulate for a predetermined timeframe 21. The recorded temperature information may be transferred to a data logger as appreciated.
