Electric pressure cooker with pressure relieving function

Abstract

The invention relates to an electric pressure cooker with a pressure relieving function. The electric pressure cooker comprises a cooker body, a cooker cover and a jet flow impact cooling device, wherein the cooker cover is matched with the cooker body to be used; the jet flow impact cooling device comprises a circulation water path, a jet flow pump connected onto the circulation water path and aspraying device arranged in the pot cover; and the spraying device communicates with the circulation water path. The temperature in the cooker is fast lowered by using the jet flow impact cooling cooker cover; the reduction speed of the pressure in the cooker is further accelerated; the pressure relieving time is shortened; by using strong heat exchange capability of the jet flow impact cooling, the demanding quantity of the cooling water can be reduced; and the size of a water storage device and the size of the whole electric pressure cooker are reduced.

Description

technical field [0001] The invention relates to the technical field of electric pressure cookers, in particular to an electric pressure cooker with a pressure relief function. Background technique [0002] With the quickening pace of people's life, kitchen cooking utensils need to meet people's needs for quickness and convenience. The existing electric pressure cooker has many advantages such as fast cooking, high cooking temperature, less nutrient loss of cooking food, good food taste, power saving, etc., and has become an indispensable cooking utensil in the family kitchen. However, after the cooking work of the traditional electric pressure cooker is over, because there is high pressure in the pot, the user cannot immediately open the pot cover, but must open or press the pressure relief valve to exhaust and reduce the pressure, or let the food in the pot cool naturally, and wait until the pot After the pressure is reduced to normal pressure, the cover can be opened to t...

AI Technical Summary

Problems solved by technology

However, after the cooking work of the traditional electric pressure cooker is over, because there is high pressure in the pot, the user cannot immediately open the pot cover, but must open or press the pressure relief valve to exhaust and reduce the pressure, or let the food in the pot cool naturally, and wait until the pot Only when the pressure is reduced to normal pressure can the lid be opened to take out the food. Because the lid cannot be opened quickly after fast cooking and the food cannot be enjoyed immediately, resulting in a long waiting time, which brings great inconvenience to the user

[0003] In order to solve the technical problem that the traditional electric pressure cooker cannot be quickly opened, some technical solutions have been proposed in the industry: first, the cooling air blown by the cooling fan cools the inner pot or the lid after cooking, but in the actual application process It is found that the air cooling effect is not obvious, and the user still cannot open the pot cover quickly; the second is to actively discharge the gas in the pot through the exhaust device installed on the pot cover after cooking, and when the user opens or presses the pressure relief valve In the process of exhausting and depressurizing, if the food in the pot is liquid food, the liquid food in the pot is easily ejected from the exhaust port by high-pressure steam, causing danger to the user and polluting the inner and outer surfaces of the pot and the environment , causing cleaning problems
