Anti-liner-suction cooking utensil

Abstract

The invention discloses an anti-liner-suction cooking utensil which comprises a pot body, wherein a liner is arranged in the pot body; and a cooker cover which is provided with a sealing ring, whereinthe sealing ring comprises a sealing ring body, a lower lip and an upper lip, one end of the lower lip is fixedly connected with the sealing ring body, the other end of the lower lip extends downwards, at least part of the lower lip can be in sealing fit with the inner wall face of the inner container, one end of the upper lip is fixedly connected with the sealing ring body and / or the lower lip,and the other end is a free end; when the cooker cover is in a state of buckling the cooker body, the upper lip edge is provided with a first position which abuts against the inner container to seal the inner container and a second position which moves towards the lower lip edge to be separated from the inner container so that an air inlet gap can be formed between the upper lip edge and the innercontainer. Due to the structural design of the sealing ring, when the cover is opened, external air can quickly enter the inner container through the gap between the sealing ring and the inner container, so that negative pressure is eliminated, the inner container is prevented from being sucked, and a user can open the cover conveniently.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, and in particular relates to a gallbladder-absorbing-proof cooking appliance. Background technique [0002] Existing pressure cooking utensils generally include a pot body and a pot cover, an inner container is provided in the pot body, and a sealing ring is provided between the pot cover and the inner container, so that the gap between the pot cover and the inner container is form a closed cooking cavity. After the cooking is completed, the pressure in the pot is released through the pressure relief valve, and the float on the pot cover falls, and the pressure inside and outside the pot is close to each other. At this time, when the lid opening button is pressed, the pot lid will be delayed to open, and bile suction will occur, that is, The lid and the liner are adsorbed together, resulting in the phenomenon that the lid cannot be opened smoothly. The main reason for this phenomenon...

AI Technical Summary

Problems solved by technology

[0004] The contact area between the upper lip and the edge of the inner container is large, thereby increasing the mutual adsorption force between the two. During the process of opening the cover, the joint between the upper lip and the edge of the inner container blocks the entry of external air , the air in the gallbladder cannot be replenished in time and effectively, and the negative pressure in the gallbladder cannot be eliminated, which aggravates the problem of gallbladder suction. It is difficult for users to open the upper cover in a short time, which reduces the user experience; When the upper cover is pushed up hard, the inner tank will be lifted under the action of the adsorption force, and then fall down, the high-temperature soup in the pot will splash and scald the user, causing a safety accident;

[0005] The dimensional accuracy of the sealing ring is high. If the size of the sealing ring is too large due to manufacturing errors, when the lid is fastened on the pot body, the gap between the sealing ring and the inner tank will become very small or even zero, so that Creates convenient conditions for the phenomenon of bile absorption, which will cause serious bile absorption
