Residual soup-free self-pressure relief steam pressure cooker

Abstract

The invention relates to high-temperature steam pressure cooking kitchenware, in particular to a hotcooker type cooker supplied with heat by steam. A cooker cover of the cooker is formed by superposing and knitting fibers of plant stalks or stems; the lower edge of the cooker cover has a circular section and the diameter of Phi50 to Phi30cm, and when placed on a cooker body, is in sealed contact with the inner wall surface of the cooker body; the upper end of a steam supply pipe of a steam distribution device is provided with external threads which are connected with internal threads at the top of a steam distribution cap inversely covered on the steam supply pipe; and steam distribution holes higher than the upper edge of the cooker body are radially uniformly distributed at the upper end of the steam supply pipe. The cooker of the invention ensures short cooking time, saves energy sources, avoids residual soup left in the steam supply pipe after a dinner, is sanitary and safe to use and widely applied to foods and makes more delicious the soup of the foods; and different plant fibers may have different kinds of plant aroma and function as medicated diets to a certain extent.

Description

technical field [0001] The invention relates to a steam cooking cooker, in particular to a chafing dish type cooking pot which provides heat with steam. Background technique [0002] The use of steam to cook food has been familiar to people since ancient times. Because the cooked food is delicious, does not get angry, and is rich in nutrition, it is loved by people. [0003] Chinese patent documents 91218391.8, 200420104602.3, and 90207621.3 disclose some technical schemes of steam chafing dish, solve the problem of traditional chafing dish sticky pot, make food taste delicious, and be suitable for use in restaurants. But there are following deficiencies in these steam hot pots: [0004] ① If the cooking is not covered, and the steam is heated under normal pressure, there will be no steam pressure in the pot, the temperature is not high enough, the steam utilization rate is low, the cooking time is long, and energy is wasted; [0005] ②If it is covered, the steam will carr...

AI Technical Summary

Problems solved by technology

[0004] ① If the cooking is not covered, and the steam is heated under normal pressure, there will be no steam pressure in the pot, the temperature is not high enough, the steam utilization rate is low, the cooking time is long, and energy is wasted;

[0005] ②If it is covered, the steam will carry the soup and rush out from the surroundings, which will easily burn the people around the table and pollute the dining environment;

[0006] ③ People eat in restaurants for a short time, and they cannot cook a lot of food (such as large pieces of beef, meat with bone, meat with skin, etc.) in a short period of time, so customers' choices of food are limited;

[0007] ④Because there is no pressure and low temperature in the pot, the soup taste of the food is not enough;

[0008] ⑤The soup will enter the steam supply pipe from the low-level steam distribution hole, pollute the steam supply pipe, and the residual soup that breeds bacteria will be strung into the pot of the customer who eats next time, endangering people's health
