Split-type electric pressure cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split-type electric pressure cookers lack a safe and efficient mechanism for venting, as users must manually operate a mechanical vent valve close to the steam source, risking scalding from steam.
Innovation Solution
A split-type electric pressure cooker design featuring a power transmitting device on the cooker body and a motor driving device on the lid, allowing for electronically controlled venting through a mechanical vent valve operated by a DC motor, which prevents users from needing to manually open the vent valve near the steam source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a manual mechanical vent valve is used on the cooker lid, then the structure is simple, but users are at risk of being scalded by steam when operating the vent valve
Solution Approach 1:
The patent replaces the manual mechanical vent valve operation with an electric motor-driven system. The motor is controlled by a control circuit that receives signals from the control panel, automatically opening and closing the vent valve without requiring user proximity to the steam source. This substitution of manual mechanical operation with an automated electromechanical system eliminates the scalding risk while managing the increased device complexity through integrated control architecture.
Solution Approach 2:
The patent introduces a control circuit as an intermediary between the user interface (control panel) and the vent valve actuation mechanism. This intermediary layer processes user inputs or automated signals and controls the motor operation, allowing venting to be initiated without direct user contact with the vent valve area. The control circuit serves as a mediator that decouples the user from the hazardous steam environment while maintaining system functionality.
2Adaptability or versatility
If the cooker lid and body are completely separable, then the design is flexible and easy to clean, but power transmission between parts becomes difficult
Solution Approach 1:
The patent divides the power transmission system into two separate components: a power transmitting device mounted on the cooker body and a power receiving device mounted on the cooker lid. This segmentation allows the lid and body to be completely separable while maintaining power transmission capability when assembled. Each component can be independently manufactured, assembled, and cleaned, preserving design flexibility and ease of maintenance while enabling electronic control of the vent valve.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables safe and efficient venting by automating the process, reducing the risk of user scalding and improving product safety by maintaining the vent valve in an open state for continuous steam release.
Implementation Method 1
a power transmitting device mounted on the cooker body and able to be electrically connected to the power supply device, and the power transmitting device is used to transmit power to the power receiving device

AI summary
Disclosed is a split-type electric pressure cooker. The cooker comprises a cooker body (1) and a cooker lid (2), the cooker body (1) being provided with a power supply device. The split-type electric pressure cooker further comprises: a mechanical vent valve (21), comprising a valve seat (211) and a valve cover (212), wherein the valve seat (211) is fixedly mounted on the cooker lid (2), and the valve cover (212) can be movably mounted on the valve seat (211); a power transmitting device (12) mounted on the cooker body (1) and able to be electrically connected to the power supply device; a power receiving device (22) mounted on the cooker lid (2); and a motor driving device (23) mounted on the cooker lid (2) and electrically connected to the power receiving device (22), the motor driving device (23) being used for driving the valve cover (212) to move so as to open or close the mechanical vent valve (21). With the cooperation of the power transmitting device (12) and the power receiving device (22), the power transmission is realized between the cooker body (1) and the cooker lid (2), thereby changing the existing manual mechanical venting method into an electrically controlled venting method. By means of such design, when venting, a user does not need to manually open the vent valve at close range, thereby preventing the occurrence of the user from being scalded by steam and improving the product safety.
