Heating Cooker Electrical Layout Around the Partition Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating cookers face challenges in further shortening the depth dimension of the back portion of the heating cooker main body without interfering with the partition wall due to the arrangement of electric components like the high-voltage transformer and cooling fan.
Innovation Solution
The arrangement of the high-voltage transformer and cooling fan is optimized by incorporating a projecting portion that extends beyond the end of the heating and cooking chamber, allowing the transformer to be positioned closer to the rear wall, thus reducing the overall depth of the heating cooker.

Engineering Contradiction Analysis
1Length of stationary object
If the depth dimension of the back portion is shortened by optimizing the arrangement of electric components, then the overall size of the heating cooker is reduced, but the partition wall may interfere with the electric components
Solution Approach 1:
The high-voltage transformer is designed with an asymmetric structure where one end extends forward beyond the partition wall plane. This dimensional change in the transformer's configuration allows it to be positioned such that its main body is arranged in the back portion while avoiding interference with the partition wall, thus resolving the spatial conflict between component placement and structural elements.
2Length of stationary object
If the high-voltage transformer and cooling fan are arranged in the back portion, then the depth dimension is reduced, but further shortening is limited by partition wall interference
Solution Approach 1:
The high-voltage transformer is segmented into functionally distinct regions: a main body portion for electrical transformation and a projecting portion that extends forward. This segmentation allows the transformer to be positioned with its main body in the back portion while the projecting portion occupies the space forward of the partition wall, enabling further depth reduction without increasing arrangement complexity.

AI summary
A heating cooker includes: a heating and cooking chamber configured to heat an object to be heated; a housing configured to accommodate the heating and cooking chamber; and an electric component arranged between the heating and cooking chamber and the housing, wherein the heating and cooking chamber has a vertical wall that intersects a horizontal direction, the housing has a vertical outer wall facing the vertical wall, the electric component includes a main body portion that is arranged between the vertical outer wall and the vertical wall, and a projecting portion that projects from the main body portion in a first direction from the vertical outer wall toward the vertical wall, and at least a part of the projecting portion is located further in the first direction than an end portion in a second direction opposite to the first direction of the heating and cooking chamber.
