Gas Stove Cooker Lid With Reflective Plate for Uniform Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cookers, such as metal or ceramic pans, suffer from uneven heating, require frequent food turning, produce offensive smoke and safety concerns due to hot oil burning, and are limited in cooking diverse foods like pizza or bread, with preheating times being lengthy and unsuitable for small quantities.
Innovation Solution
A cooker design featuring a reflective plate with whirlpool-directed grooves and ridges in the lid of a gas stove cooker, which guides gas flames for uniform heat exposure and efficient smell particle removal through radiation, convection, and whirlpool circulation, allowing multidimensional heating and quick cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional metal or ceramic pan is used for cooking, then the heating plate can be simple in structure, but the heat distribution becomes uneven requiring frequent food turning
Solution Approach 1:
The reflective plate introduces a vertical dimension to heat distribution by reflecting flames upward and outward onto the lid's inner surface, creating multidimensional heat exposure (from below through the pan and from above through the lid) rather than conventional single-direction heating
Solution Approach 2:
The reflective plate is segmented with radial grooves that divide the flame path into multiple zones, directing heat to different areas of the lid systematically to achieve uniform heat distribution across the cooking surface
2Object-affected harmful factors
If a metal heating plate is used, then the cooker structure remains simple, but smoke and smell particles are generated causing pollution and safety concerns
Solution Approach 1:
The reflective plate converts harmful direct flames and hot gases that would otherwise escape into the environment into beneficial heating elements by reflecting them onto the lid's inner surface, thereby reducing smoke and smell particle emission while improving heat distribution
Solution Approach 2:
The reflective plate acts as an intermediary surface between the gas flame and the food, mediating the heat transfer process by reflecting and redistributing thermal energy while containing smoke and smell particles within the cooking chamber
3Adaptability or versatility
If an oven is used for cooking various foods like pizza or bread, then cooking versatility is improved, but preheating time increases significantly
Solution Approach 1:
The cooker achieves multi-functionality by combining direct flame heating through the pan with reflected flame heating through the lid, enabling it to cook various foods (pizza, bread, grilled items, stews) in a single device without requiring separate oven preheating
Solution Approach 2:
The reflective plate is pre-configured with radial grooves and specific geometry to automatically direct and distribute flames uniformly across the lid surface as soon as the gas is ignited, eliminating the need for preliminary preheating that conventional ovens require

AI summary
The present invention relates to a cooker for use with a gas stove, which provides uniform heat exposure and at the same time removing smell particles by generating radiation, convection, whirlpool circulation in the lid of the cooker through a reflective plate mounted in the lid. The reflective plate has grooves and ridges evenly provided in whirlpool directions from its centre to it outer edge so that the gas flame induces descending diffraction and refraction toward the extreme outer edge of the reflective plate after being guided naturally along whirlpool directions. Thus, the present invention provides a cooker having a fast and multidimensional heating system.
