Description

Technical Field

[0001] The invention relates to the field of electrical appliances, and in particular to an electric rice cooker. Background Art

[0002] Sushi is a typical vinegar-flavored food. The large amount of acetic acid used in its production and consumption is very beneficial to human health. The lactic acid produced after acetic acid processing not only sterilizes and disinfects raw and cold foods, but also helps to remove intestinal bacteria and aid digestion. In addition, the various nutrients in seafood have the function of curing diseases and promoting health. The most traditional sushi is mainly made of raw fish, rice and refined salt, and is made after months of pickling and fermentation. With the rapid development of society, this kind of sushi made by traditional methods is no longer common. At present, most sushi uses the method of mixing rice with vinegar to process its main ingredients, and adds auxiliary ingredients such as sour radish and dried radish according to different people's tastes. However, whether it is traditional or modern sushi, the combination of rice and vinegar is still the basis of sushi making. Moreover, with the improvement of living standards, people have higher and higher requirements for the taste of sushi rice. Therefore, in order to meet the requirements of more consumers, further improvements need to be made to the processing of sushi rice. However, the improvement of sushi rice in the prior art is mainly to mix the cooked sushi rice with other ingredients or other seasonings to achieve the purpose of improving the taste, and there is no improvement on the cooking process of sushi rice. There are few devices developed for cooking sushi rice. Generally, sushi rice is cooked by ordinary rice cookers combined with experience. This method of making sushi rice has low universality. Therefore, there is a need for an electric rice cooker that can meet the needs of consumers and can be used to cook sushi rice with excellent taste.
