Vacuum Cooker Pump Layout for Lighter Covers and Stable Vacuum
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum electric cookers with integrated suction pumps are bulky, heavy, and stressful on the container, leading to potential breakage and inefficient vacuum maintenance during cooking, which compromises the freshness of food.
Innovation Solution
The vacuum electric cooker design relocates the vacuum pump to the cooker body, using a connecting arm and nozzle system with a trap member and air-flow control to prevent food and liquids from entering the pump, and incorporates control means to maintain a predetermined vacuum level during cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction pump is integrated into the cover, then the vacuum function is achieved, but the cover becomes bulky and heavy, causing stress on the container and potential breakage
Solution Approach 1:
The suction pump is extracted from the cover and relocated to the base of the vacuum electric cooker. The cover now only contains the discharge nozzle, significantly reducing its weight and structural complexity while maintaining the vacuum function through the relocated pump system.
2Reliability
If the suction pump is integrated into the cover, then the vacuum function is achieved, but the structure becomes bulky and complex, making operation difficult
Solution Approach 1:
The suction pump is extracted from the cover and placed in the base, simplifying the cover structure to only include the discharge nozzle. This extraction makes the cover lighter and easier to handle, install, and operate while the vacuum function is maintained through the base-mounted pump system.
3Reliability
If the suction pump is integrated into the cover, then the vacuum function is achieved, but the stress on the container increases, causing potential breakage
Solution Approach 1:
The suction pump is extracted from the cover and relocated to the base, eliminating the heavy structure from the cover. This reduces the stress and weight burden on the container, preventing potential breakage while maintaining the vacuum function through the base-mounted pump and connecting arm system.
