Double-liner electric cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric cookers with a single liner are inefficient for large food quantities, occupy excessive kitchen space, and have cumbersome sealing mechanisms prone to deformation, leading to poor sealing and ease of use issues.
Innovation Solution
A double-liner electric cooker design with two inner cavities separated by a thermal insulation plate, featuring intersecting hinge shafts for easy opening, snap-fastened sealing members, and a rigid construction to prevent deformation, allowing for independent heating and reduced volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electric cookers are used to cook large amounts of food, then cooking capacity is improved, but kitchen space occupation increases
Solution Approach 1:
The patent combines two cooking chambers into a single electric cooker body, allowing simultaneous cooking of large amounts of food in one appliance rather than requiring multiple separate cookers. The cooker body includes a first cooking chamber and a second cooking chamber that share common structural components, achieving space-efficient multi-functionality.
Solution Approach 2:
The electric cooker is designed with dual cooking chambers that can independently perform various cooking functions (steaming, boiling, stewing, baking, braising), making the single appliance capable of handling diverse cooking tasks that previously required multiple specialized devices.
2Reliability
If a sealing member is used to seal the cooker cover, then sealing effect is improved, but ease of assembly and cleaning deteriorates
Solution Approach 1:
The sealing member is designed as a separable component that can be easily detached from the cooker cover. The sealing member includes a sealing body with a sealing surface that contacts the cooker body, and it can be independently removed for cleaning or replacement without disassembling the entire cooker cover assembly.
Solution Approach 2:
The sealing member is extracted as a standalone replaceable component from the cooker cover assembly. It is mounted in a sealing groove but can be easily removed by pulling it out, allowing users to clean or replace the sealing member without affecting other parts of the cooker cover.
3Strength
If the cooker cover is made rigid to maintain structure, then strength is improved, but susceptibility to heat and steam deformation increases
Solution Approach 1:
The cooker cover is designed with non-uniform thickness distribution, being thicker at the rim portion that contacts the sealing member and thinner at other areas. This local quality variation provides enhanced structural strength where needed for sealing while reducing overall material and improving heat resistance.
Solution Approach 2:
The cooker cover is made from heat-resistant composite materials that combine high strength with resistance to thermal deformation. The material composition is selected to maintain structural integrity under the thermal and steam conditions encountered during cooking operations.
4Device complexity
If one liner is used per electric cooker, then simplicity is improved, but cooking efficiency for different foods deteriorates
Solution Approach 1:
The electric cooker integrates two separate cooking chambers into one appliance, each chamber capable of holding a liner for cooking different types of food simultaneously. This merging allows users to cook multiple dishes at once without requiring multiple separate cookers.
Solution Approach 2:
Each cooking chamber is designed with universal compatibility for standard liners, allowing the same basic structure to support various cooking functions. The dual-chamber design provides multi-functionality for simultaneous preparation of different meals.

AI summary
Disclosed is a double-liner electric cooker, comprising a cooker body, liners and cooker covers, wherein two liners and two cooker covers are provided, the cooker body is provided with a first inner cavity, two first inner cavities are mutually separated via a thermal insulation plate, and the two first inner cavities are both provided with cavity openings for the liners to be placed therein; the rear ends of the two cooker covers are respectively hinged to the edges of the cavity openings via hinge shafts, and the axial directions of the two hinge shafts intersect. The electric cooker is convenient to open, and on the basis that the sealing members are convenient to assemble and disassemble, the cooker cover can still maintain good sealing effects.
