DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION

Overview

(18) For a better understanding of the invention, specific examples of forms and embodiments the invention can take will now be set forth in detail. Frequent reference will be made to the appended drawings. Reference numbers will be used to indicate certain parts and locations in the drawings. The same reference numerals will be used to indicate the same parts and locations throughout the drawings unless otherwise indicated.

(19) This exemplary embodiment will be described in the context of a home with a pipe including frozen material where the pipe is located in the ground outside of the home. It is to be understood, however, that the location of the frozen material in the pipe and of the pipe itself is of no consequence to the present invention. In general, the invention may be used to thaw frozen material from any pipe in any location, so long as it is fluidly connected to an opening. Therefore, the present invention is not to be limited by the pipe location, the location of the frozen material, or the type of frozen material.

(20) FIG. 1 shows the present invention 10 being used to thaw frozen material 12 from a pipe 14. In one embodiment, the present invention 10 includes a conduit 16 through which a plurality of wires 18 pass. The wires 18 connect to a power source 20 which may be accessed using a standard 110 Volt outlet plug-in 22 on one end of the wires 18. The present invention 10 may also be powered by a 220 Volt outlet source or by battery power. Operatively connected to the other end of the wires is a heating element 24. The heating element 24 may be made of a material that turns electrical current into heat through resistive heating. For example, nichrome, which is a combination of nickel and chromium, may be used. Other heating elements, such as infrared lights, heating wire or any other electrically powered heating element may be used.

(21) The heating element is controlled by a thermostat 26 or other control system. The thermostat 26 works in conjunction with one or more sensors 28, such as a thermocouple, to ensure the heating element 24 is maintained at or about a preferred temperature, the preferred temperature being at least above the melting point for the frozen material 12. The thermostat 26 can also be used to turn the heating element 24 on and off.

(22) As the heating element 24 is intended to conduct heat near ice or other frozen material 12, it is preferred that the heating element 24 be water proof or at least water resistant. As shown in FIG. 2, the heating element 24 is preferably encased in a shell 30 of plastic, metal or any other material that allows sufficient heat transfer and water resistance. The shell 30 may be a plastic material that is molded around the heating element 24. Because the heating element 24 and shell 30 are frequently subjected to contact with the pipe 14 or frozen material 12, it is likely the heating element 24 will need to be replaced periodically. Rather than requiring the purchase of an entirely new apparatus 10, the user of the present invention 10 preferably can simply replace the heating element 24 and shell 30, which may be multiple pieces or formed together as a single, removable piece 32.

(23) The removable piece 32 is secured to the conduit 16 by a plug 34. The plug 34 includes a securing member 36 or profile that fits into a receiving end 38 of the conduit 16. For example, the securing member 36 of the plug 34 may be threads that screw into a threaded end of the conduit 16. If desired, the plug 34 may be more permanently affixed to the conduit 16 through shrink wrapping the area where the plug 34 and conduit 16 meet.

(24) The plug 34 also includes electrical connections 40 that operatively connect the heating element 24 to the wires 18 and ultimately to the power source 20. The electrical connections can be similar to those found in a light bulb, ensuring the present invention 10 may also be used as a lighting source. For example, in such a situation, the heating element 24 may be replaced with a light bulb 42 in the present invention 10. Other attachments, such as a camera 44, microphone 46 or hardened end 48 may be used as desired.

Options and Alternatives

(25) It will be appreciated that the invention can take many forms and embodiments. Just a few examples have been set forth above. Variations obvious to those skilled in the art will be included within the invention which is defined solely by the appended claims.
