The invention relates to a uniformly heated cooking utensil. The cooking utensil comprises a pot body and a cover body. The pot body is provided with a heating plate and an inner gallbladder above it. The inner gallbladder comprises a first arc transition part and a side wall and a bottom wall connected with it respectively. The heating plate is provided with an inner ring heating area and an outer ring heating area. The inner ring heating area and the inner gallbladder are arranged between the inner ring heating area and the inner gallbladder. The first clearance, the outer ring heating area and the outer surface of the inner gallbladder are fitted together. With this technology, the temperature of the heating area on the inner gallbladder and the outer ring of the heating plate is higher than that corresponding to the inner ring, and then a strong heating area and a weak heating area are formed on the inner gallbladder. During the cooking process of rice, especially in the stage of water absorption and heating, the temperature of the inner gallbladder side rises rapidly, which promotes the water absorption of the rice in the first transition region in advance and avoids the lack of water in the later cooking period. Water causes the problem of hard rice, and eventually cooked rice has better uniformity.

一种均匀加热的烹饪器具
本专利技术涉及烹饪家用电器领域,尤其涉及一种均匀加热的烹饪器具。
技术介绍
饭煲是现有家庭中的必备的烹饪器具,随着人们对于生活水平的提高,对于饭煲烹饪的质量要求也越来越高,但是,由于目前大多数饭煲都是采用平盘状发热盘加热,由于加工误差的存在以及加热过程中的内胆变形,制作出的米饭均匀性不好。现有技术中提出了一种改进的方案,具体是通过将普通的平盘状发热盘改进为内凹的碗状结构,通过增加发热盘表面与内胆的接触面积来保证均匀加热性,但发热盘与内胆也只是在冷态时贴合完全,在实际烹饪时发热盘与内胆均处于热膨胀状态,再加上两者之间的膨胀率和膨胀方向不同导致无法完全贴合。对此,现有技术CN201620247009.7中还提出了一种改进方案,具体是在与内锅底壁配合的第一盘体与内锅的外壁面之间设置第一间隙,以及在盘体的延伸部与内锅的外壁面之间设置第二间隙,通过间隙的设置为盘体受热变形预留了一定的变形空间,从而防止发热盘受热变形后与内锅干涉,该方案实际上是使加热过程中内胆变形从而能够消除间隙,进而增加发热盘表面与内胆的接触面积。因此,上述现有技术的根本目的在于增加 ...
