Heating Cooker Irradiator Reflector Light Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heating cooker design suffers from reduced light irradiation within the heating compartment due to the interior lighting being disposed outside the inner box, leading to light not passing through the ceiling intake port, especially as the separation distance between the lighting and the intake port increases.
Innovation Solution
The heating cooker incorporates an irradiator disposed on the outer side of the heating cooking compartment, which irradiates the interior with light, and a reflector positioned opposite to the compartment to reflect light emitted from the irradiator. The design includes specific openings in the wall portion to allow both direct and reflected light to pass through, thereby increasing the light irradiation within the compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the interior lighting is disposed outside the inner box, then the lighting structure is simplified and easier to manufacture, but the amount of light irradiating the heating compartment is reduced
Solution Approach 1:
The patent transitions from a single direct lighting path to a multi-dimensional lighting system by adding a reflector that creates indirect light paths. The reflector is positioned at an angle (e.g., 45 degrees) to the irradiator, reflecting light onto the ceiling and sides of the heating compartment, thereby adding spatial dimensions to light distribution and increasing overall illumination coverage.
Solution Approach 2:
The reflector acts as an intermediary element between the irradiator and the heating compartment interior. Instead of light directly illuminating all areas, the reflector mediates by catching light from the irradiator and redirecting it to the ceiling and walls, ensuring more uniform and comprehensive illumination throughout the compartment.
2Adaptability or versatility
If the separation distance between the interior lighting and the ceiling intake port increases, then the lighting can be positioned more flexibly, but the amount of light passing through the intake port decreases
Solution Approach 1:
The reflector introduces additional light paths by reflecting light onto the ceiling and sides of the compartment. This creates multiple illumination zones and ensures that even areas far from the irradiator receive adequate light, effectively decoupling the lighting performance from the strict proximity requirement to the intake port.
Solution Approach 2:
The reflector is strategically positioned to target specific areas of the heating compartment, such as the ceiling and side walls, with reflected light. This creates localized illumination zones that complement the direct light from the irradiator, ensuring comprehensive coverage throughout the compartment regardless of the irradiator's distance from the intake port.

Function Achieved in This Case
This configuration effectively increases the amount of light irradiating the inside of the heating cooking compartment, enhancing illumination and cooking efficiency.
Implementation Method 1
The reflector is disposed at a position on the wall portion opposite to the heating cooking compartment and reflects light emitted from the irradiator

AI summary
A heating cooker includes a heating cooking compartment, an upper wall, an irradiator, and a reflector. The heating cooking compartment allows a heating-target object to be accommodated therein. The upper wall constitutes at least a part of the heating cooking compartment. The irradiator is disposed on an outer side of the heating cooking compartment with respect to an upper wall and irradiates an inside of the heating cooking compartment with light from an outside of the heating cooking compartment. The reflector is disposed at a position on the upper wall opposite to the heating cooking compartment, and reflects light emitted from the irradiator. The upper wall has a first opening configured to allow light emitted from the irradiator to pass through, and a second opening configured to allow light reflected from the reflector to pass through.
