发明名称 Heating device adapted to maintain an open hole in ice
摘要 Disclosed is a water spitter for maintaining an opening in ice for the purpose of ice fishing. The water spitter has an outer reservoir placed circumferentially about an inner heating chamber. The heating chamber is internally lined with a coiled tube. The coiled tube passes through the bottom wall of the inner heating chamber and has an inlet located within the outer reservoir. The coiled tube additionally passes out of the inner heating chamber to an outlet which can be directed to the hole in the ice. By filling the outer reservoir with water and filling the inner heating chamber with charcoal or other combustible material and igniting the combustible material, a fisherman can direct a volume and temperature controlled stream of heated water into the hole. Additional features are disclosed which provide advantages of unrestricted portability, compact pack-up, and positional stability during operation.
