Houses which use only electricity are becoming popular in Japan. Electromagnetic ranges (IH range)are used in those houses. The updraft above an IH range is slower than a gas range. The requiredventilation rate is different for a gas range and an IH range. In this study, measurements of updraftvelocity and temperature distribution above the IH ranges are conducted. The required ventilation ratefor the home kitchen with IH ranges are proposed by this study.Results are as follows: The position of the maximum air flow velocity, when one range is operated, isdirectly above the range, and when two ranges are operated, it is in the center of the two ranges. Theupdraft air flow rate is strongly influenced by the number of ranges. The capture ratio has fewdifferences pertaining to power value of a range. When the number of ranges increases, the captureratio is small. When two ranges are operated and the capture ratio is 80%, the required ventilation rateis about 150m3/h.
