Automatic steam exhausting electric pressure cooker

Abstract

The invention provides an automatic steam exhausting electric pressure cooker. The cooker comprises a cooker cover, a cooker inner container, a cooker body and a cantilever hinged with the cooker body, wherein the center of the cooker cover is rotationally pivoted to the cantilever; the cooker cover is rotationally buckled with or separated from the cooker body and provided with a counter weight pressure limiting valve; the cantilever is provided with an electromagnetic push rod; when the cooker cover is buckled with the cooker body, the electromagnetic push rod is close to the counter weight pressure limiting valve and can drive the counter weight pressure limiting valve to exhaust steam and release pressure; and when the cooker cover is separated from the cooker body, the electromagnetic push rod is far away from the counter weight pressure limiting valve. Compared with the prior art, the electric pressure cooker of the invention has the advantages of realizing automatic steam exhausting and pressure releasing through cooperating action of the electromagnetic push rod and the pressure limiting valve, ensuring that the cooker can only be opened under the condition that foods are boiled completely, eliminating the safety potential hazard of user scalding, further expanding application range and saving cost, along with simpler structure, more convenient installation and no occupation of internal space.

Description

technical field [0001] The invention relates to an electric pressure cooker for kitchen cooking utensils, in particular to an electric pressure cooker with automatic steam exhaust. Background technique [0002] Because the electric pressure cooker is in a high-pressure environment when cooking, the user needs to wait for the high-temperature steam in the pot to completely liquefy into water after the electric heating device stops heating before opening the lid safely. Generally, after the electric pressure cooker stops heating and waits for a period of time, Manual steam exhaust and pressure relief is implemented by manually rotating the heavy hammer pressure limiting valve, and then the pot cover is opened. However, in the above method of manual steam exhaust, it is difficult to confirm whether the food in the pot is fully cooked before exhausting steam, and the food may not be fully cooked due to insufficient heat preservation time due to premature steam exhaust; If the ...

AI Technical Summary

Problems solved by technology

However, in the above method of manual steam exhaust, it is difficult to confirm whether the food in the pot is fully cooked before exhausting steam, and the food may not be fully cooked due to insufficient heat preservation time due to premature steam exhaust; If the user does not operate properly, the high-temperature steam discharged from the heavy hammer pressure limiting valve will burn the user and cause dangerous safety issues

And because the steam can only be exhausted manually, some foods that need air circulation to achieve better cooking effects during cooking are inconvenient to cook in the electric pressure cooker, which limits the scope of use of the electric pressure cooker

Moreover, because the inside of the electric pressure cooker is a high-pressure environment, it is generally impossible to achieve boiling during the cooking process. In the high-pressure environment of the electric pressure cooker, food generally can only be mixed through the convective movement of molecules, and the mixing is not sufficient enough to achieve boiling in a large range. and mix thoroughly

For food like porridge and soup, the cooking effect is not good

[0003] At present, there are some electric pressure cookers on the market that can realize automatic steam exhaust, but the existing automatic steam exhaust devices are usually installed inside the electric pressure cooker, which requires a large installation space. Moreover, when the automatic exhaust device fails, maintenance is also very inconvenient
