Inventor: IMAI ITSUJI
IPC: F24H9/00
Filed: 1984-10-11
Abstract: PURPOSE:To prevent cooling due to dissipation of heat and contrive saving of fuel as well as shortening of boiling time by a method wherein the range of propagation of heat of heated water is narrowed temperarily to increase the impregnating speed of the heat. CONSTITUTION:In order to divide the contents of the vessel into two parts A, B, a partitioning plate is made of a flat and thin galvanized iron sheet, plastic sheet or the like and the rims of the sheet, which are made so as to meet with the inside dimensions of the vessel, are covered by rubber, vinyl or the like to improve contact between the vessel and the plate. A quick boiling plate (b) is forced into the vessel vertically at the center of the vessel substantially to divide water or liquid in the vessel into two parts A, B and cut the communication or mixing of the contents as a boundary. Heating is effected in the part A only, which is near a heat supplying port, and the part B absorbs heat through the quick boiling plate (b) while heat source is circulated quickly in only the part A and the quick boiling plate (b) is removed when the temperature of the part A has arrived at a high temperature to obtain the hot-water of proper temperature by mixing it into the low-temperature part B. According to this method, fuel may be saved and the time for boiling may be shortened.
