Description

Self-defoaming pressure cooker

Technical Field

The invention relates to the technical field of kitchen utensils, in particular to a self-defoaming pressure cooker.

Background

The pressure cooker is also called pressure cooker and pressure cooker, and is a cooker in kitchen. 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.

At present, an exhaust pipe is arranged on a pot cover of the existing pressure cooker, a pressure release valve is sleeved at the upper end of the exhaust pipe, and when the air pressure of a pot body is overlarge, the pressure release valve can be jacked up and rotated to exhaust outwards through air flow, so that explosion accidents caused by overlarge air pressure in the pot body are avoided; however, the existing pressure cooker is easy to generate a large amount of bubbles when stewing food, and the bubbles carry a large amount of sundry food to overflow from the exhaust pipe, so that not only can a large amount of food be wasted, but also water stains generated after the bubbles are broken in the pressure release valve can be thrown out in the process of quick rotation of the pressure release valve, and a user has to spend a large amount of time cleaning a cooking bench and a cooking utensil; when a user cooks and cooks food near a cooking bench, the high-temperature liquid water mixed with the finely-divided food can be thrown to the body of the user, and scalding accidents are easily caused; in addition, the food overflowing from the exhaust pipe and entering the pressure release valve easily blocks the exhaust hole on the valve body, so that the exhaust of the pressure release valve is blocked, the air pressure in the pressure cooker greatly exceeds a critical value, and safety accidents are easily caused if blockage is not timely cleared.
