Electric hot tray and cooking utensil

The utility model discloses an electric hot tray and a cooking utensil, and relates to the field of electric heating. An electric heating wire comprises a paper substrate, and the two faces of the electric heating wire are covered with inorganic insulating plates and fixed through the clamping force of a metal cover plate and a buckle. The electric hot tray has the advantages of higher working temperature and power density. In order to avoid poor heat dissipation caused by thermal expansion of the heating wire, the length of the continuous line segment of the heating wire does not exceed 30mm, or the product of the length and the power density does not exceed 20. The cooking utensil comprises the electric hot tray. 本实用新型公开了一种电热盘和一种烹饪器具，涉及电热领域。一种电热盘，电热丝包含纸基板，电热丝的两面覆盖无机绝缘板，依靠金属盖板和扣具的夹力固定；优点是电热盘的工作温度和功率密度更高。为了避免电热丝的热膨胀导致散热不良，电热丝连续线段的长度不超过30mm，或者与功率密度的乘积不超过20。一种烹饪器具包括有上述电热盘。
