Description

Pressure release assembly and pressure cooker

Technical Field

The utility model belongs to the field of pressure relief, and particularly relates to a pressure relief assembly and a pressure cooker.

Background

The electric pressure cooker has the function of pressure rapid cooking, and the purpose of improving the cooking temperature and shortening the cooking time is achieved by pressurizing water vapor generated by sealing and heating food. The pressure cooker or the pressure pot becomes an indispensable cooking utensil for modern fast-paced life, but after the pressure cooking work is finished, a user cannot immediately uncover food, especially soup, fluid or viscous food, and cannot directly deflate for quick cooling, and long waiting time is needed for natural cooling because the pressure in the cooker is higher than the atmospheric pressure. If the pressure in the cooker is higher, the more heat needs to be released, the longer the normal cooling time is needed, the purpose of quick cooking is not achieved, and the experience of life users with fast rhythm is poor.

In addition, when food is pressure-cooked, the pressure cooker calculates the pressure cooking time, and the additional cooking time generated in the pressure cooker pressure-reducing process is not calculated, so that the actual pressure cooking time of the food is prolonged, the pressure cooking time set by the food is different from the actual cooking time, the taste of the food is influenced by the slow pressure release of the pressure cooker, and particularly, the taste of the food sensitive to the pressure cooking time is influenced more.

Therefore, the quick pressure release of the electric pressure cooker becomes an industry problem. Air forced convection cooling is one of the schemes for rapid cooling. According to the method, the rear part of the electric pressure cooker is used as a fan installation position, the top fins are used for performing an air cooling scheme, and the fan is connected with the fins by adopting a proper air passing pipeline, so that the electric pressure cooker becomes one of general design schemes for quick pressure relief of the electric pressure cooker. Because the air is guided by the fan on the pot body to cool the upper cover, the air passage can be subjected to a bending process due to the opening and closing of the cover through the hinge.

However, after the existing air passage is bent, due to the action of tensile stress, collapse occurs on one stretched side of the air passage, so that the air passage sectional area of the bent part is reduced, and the ventilation efficiency is affected.
