Description

Quick pressure relief structure of pressure cooker

Technical Field

The utility model relates to a pressure cooker technical field specifically is a quick release structure of pressure cooker.

Background

The pressure cooker can raise the physical phenomenon that the boiling point of liquid under higher air pressure exerts pressure on water, so that the water can reach higher temperature without boiling, thereby accelerating the efficiency of stewing food. The utility model can heat the cooked food to more than 100 ℃, and in high altitude areas, the pressure cooker can avoid the problem that the food is not easy to cook because the boiling point of water is reduced.

After the pressure cooker finishes the cooking work, the cooker cover can be opened only after the cooker body is cooled in order to ensure the safety because of the high pressure in the cooker. The common method comprises natural cooling at room temperature, or spraying cold water on the pressure cooker for cooling, realizing pressure relief function, and opening the cooker cover.

However, such techniques have the following disadvantages: the waiting time is longer, generally 10-30 minutes, and if the altitude area is formed, the waiting time is longer. This affects the taste of food, especially for food with soup such as noodles, etc., either the food is too cooked by the heat in the pressure cooker due to long time of opening the cover, or people stop heating the pressure cooker in advance and want to cook the noodles by the residual heat in the cooker, which is not good to control the timing of turning off the fire, often resulting in the cooked filling, the cooked noodles, and the taste is poor. Especially for families living in cloud, noble, Sichuan, sweet, green, new and other high-altitude areas, the families mostly like the pasta, which brings inconvenience to users.

Disclosure of Invention

For overcoming the deficiencies of the prior art, the utility model provides a quick release structure of pressure cooker solves the pressure release that current pressure cooker exists and takes a long time, influences food taste scheduling problem easily.

The utility model provides a quick release structure of pressure cooker, includes pot cover, the pot body, still includes water pipe, water storage device, on-off valve, discharge valve, the one end of water pipe is put through with water storage device mutually, and the other end of water pipe stretches into the pot internally, on-off valve is used for controlling the break-make of the pipeline between water pipe and the water storage device, discharge valve is used for controlling the internal atmospheric break-make of pot and pot body outside.

In the technical scheme, after food with soup (such as noodles and the like) is cooked in a pot body at high pressure, the on-off valve is placed in an on state, the pot body is in a high-pressure state, the water storage device is in a normal-pressure state, the soup in the pot body rapidly enters the water storage device through the water pipe due to the pressure difference, after the soup in the pot body completely enters the water storage device, the on-off valve is placed in an off state, most of pressure in the pot body is released at the moment, the condition of opening the pot cover is met, the rest pressure generated by steam can be discharged by opening the exhaust valve, and the on-off valve is placed in an on state, so that the soup in the water storage device flows back to the pot body.
