ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to a whistling device for a cooker lid and in particular, to a handle block mounted onto a cooker lid to adjust the size of an opening between the venting recess of a handle block and the venting recess of an annular block, so that the adjustment of the handle block of the cooker lid can control the volume of the sound and the amount of hot air released from a cooker.
b) Description of the Prior Art
Recently, various types of safety devices and alarming devices are provided to cooking utensils in order to provide safety and convenience to the user. Frequently, a whistle is provided to the cooker lid so that the hot air produced during cooking provides an alarming sound to alert the user. However, for cooker lids having a glass window, no whittling device is provided as a result of its complicated structure. There is only an air vent provided on the cooker lid. If a whistling device is to be mounted onto the glass mounted cooker lid, the structure of the whistling device may be very complicated and expensive to manufacture.
Therefore, it is an object of the present invention to provide an improvement in the structure of a whistling device for a cooker lid which can obviate and mitigate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
It is the primary object of the present invention to provide a whistling device for a cooker includes a cooker lid, an annular block, a handle block, and a screw, characterized in that the cooker lid is circular and is having a center opening and a venting hole; the annular block is circular and has a circular opening, an annular groove at a bottom of the annular block, a venting recess in communication with the annular groove, and a protruded arch on a top of the annular block and located above the venting recess; the handle block is generally circular in shape and has a protrusion extending downwardly from a center of a bottom thereof, the protrusion being formed with a center threaded hole aligned with the center opening of the cooker lid, the protrusion being sized to fit within the center opening of the annular block and formed with an annular slot for receiving the annular block, the handle block having a venting recess at a bottom thereof in alignment with the venting recess of the annular block and an arch-shaped slot slidably engaged with the protruded arch of the annular block, the handle block having an arch-shaped handle diametrically mounted across the edge thereof; and a screw extending upwardly through the center opening of the cooker lid to engage with the threaded hole of the handle block.
It is another object of the present invention to provide a whistling device of a cooker lid which can mitigate the drawbacks of the conventional cooker lid with alarming device.
The various features of novelty which characterize the invention are pointed out with particularity in the claim annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects obtained by its uses, references is made to the accompanying drawings and descriptive matter in which preferred embodiment of the invention is illustrated.
