Description

Pressure limiting valve, pot cover and cooking utensil

Technical Field

The utility model relates to a small household appliances field particularly, relates to a pressure limiting valve, pot cover and cooking utensil.

Background

The electric pressure cooker is used by consumers because of easy cooking of food difficult to cook. The electric pressure cooker is provided with a pressure limiting valve which is used as a main key part for pressure control, and the pressure limiting valve supports against an exhaust pipe by the gravity of the pressure limiting valve to realize the rise of the pressure in the cooker. If the pressure in the cooker is too high, the high-temperature steam will open the pressure limiting valve and be discharged from the exhaust pipe to reduce the pressure.

In the exhaust process, high-temperature steam is directly exhausted from the air outlet on the pressure limiting valve to the area above the pressure limiting valve to form a large amount of steam. Because the kitchen is generally smaller at present, and in order to improve space utilization, all install the wall cabinet, this just leads to in culinary art process, and a large amount of high temperature steam can rush to the wall cabinet, causes the wall cabinet moist, and the wall cabinet can go mildy in the time of the good time, causes the damage.

SUMMERY OF THE UTILITY MODEL

The main object of the present invention is to provide a pressure-limiting valve, a pot cover and a cooking utensil, which can solve the problem of the prior art that the gas discharged from the pressure-limiting valve is directly flushed upwards.
