DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.
Referring to FIG. 1 and FIG. 2, the first preferred embodiment of the heating assembly 1 defines a space 12 within a spiraled bent wire section 111 of the heating wire 14 of the heating device 11, and the temperature sensor 13 is placed within the space 12. In this embodiment, when the electrical source 5 passes electricity through heating wire 14, the electrical resistivity of heating wire 14 would transform the electrical energy into heat energy, thus heating the heating wire 14. The temperature sensor 13 held within the heating device 11 would then measure the temperature of heating wire 14 accurately due to its placement in space 12 and send the temperature readings to control device 4. Control device 4 would then take these readings and adjust the temperature of heating wire 14 accordingly by altering the electrical output of the electrical source 5 according to some predetermined control mechanisms. An insulating material 15 encloses both the heating device 11 and the temperature sensor 13, thus decreasing the error of the temperature readings of temperature sensor 13 caused by the environmental temperature.
FIG. 3 illustrates the second preferred embodiment of this invention, where the heating device 21 of heating assembly 2 has a section of the heating wire 24 that forms a “U” shape by being placed from one end 231 of the temperature sensor 23, along the surface of temperature sensor 23, to the other end 232 of the temperature sensor 23, and then back along another side of temperature sensor 23. Thus the curved section 211 of heating wire 24 forms a space 22 wherein temperature sensor 23 is placed. The temperature sensor 23 is sized to fit within space 22. Furthermore an insulating material 25 could enclose both the heating device 21 and temperature sensor 23, thus reducing the effects the environmental temperature has on temperature sensor 23. Once heating wire 24 starts to give off heat, temperature sensor 23 would accurately measure the temperature released by heating device 21 and send these temperature readings to control device 4. Control device 4 would then take these readings and adjust the temperature of heating wire 24 accordingly by altering the electrical output of the electrical source 5 according to some predetermined control mechanisms. The increased accuracy of the temperature sensor 23 decreases the need to restrict the range of heat released by the heating wire 24 to account for errors in the temperature readings from temperature sensor 23, thus maximizing the range of temperature which the heating device 21 could run and offering the user with safety from overheating the heating device 21 and comfort.
FIG. 4 illustrates the third preferred embodiment of this invention heating assembly 3, where a heat conducting material 36 thermally connects a section of heating wire 34 with temperature sensor 33 in order to allow temperature sensor 33 to accurately measure the temperature of heating wire 34 and to reduce the effects of the environmental temperature on temperature sensor 33.
Those skilled in the art would recognize the fact that the control device does not necessarily have to control the electrical output of the power source in order to alter the temperature of the heating wire. In essence, the control device is responsible for controlling the temperature of the heating wire; the means which the control device controls the temperature of the heating wire is not limited.
In summary of the descriptions above, this invention is a heating assembly that encloses a temperature sensor in close contact with a heating device, thus reducing environmental thermal influence on the temperature sensor and thus increasing the accuracy of the temperature sensor, hence accomplishing the goals of this invention.
While the present invention has been described in connection with what is considered the most preferred and practical embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
