Solution Overview
Problem
Conventional kilns lack efficient heating due to random wood placement, leading to suboptimal hot air circulation and energy wastage, resulting in decreased heating efficiency.
Innovation Solution
A kiln design featuring a cavity with a front, middle, and rear section, where the top wall surface of the front section tilts downward to guide hot air back to the heat source, and a heat storage member and thermal insulation structure to enhance heat retention and circulation, ensuring uniform heating of food ingredients from the top down.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wood is arbitrarily placed into the cavity without fixed position, then ease of operation is improved, but heating efficiency deteriorates
Solution Approach 1:
The cavity is divided into different sections (front section with downward tilt, middle section, rear section with upward tilt) where each section has specific functional characteristics. The front section guides hot air downward, the middle section allows circulation, and the rear section directs air back toward the heat source, creating localized functional zones that optimize heating efficiency while maintaining operational simplicity
Solution Approach 2:
The patent introduces a vertical dimension to hot air circulation by tilting the top wall surfaces of the front and rear sections. This creates a three-dimensional convection pattern where hot air rises, moves horizontally, descends along the tilted surfaces, and circulates back, transforming simple horizontal heating into efficient multi-dimensional heat distribution
2Device complexity
If hot air flow is not guided properly, then device complexity is reduced, but heat dissipation increases
Solution Approach 1:
The top wall surfaces of the front and rear sections are designed with specific tilt angles rather than being flat or curved. This angular geometry naturally guides the hot air flow in predetermined paths, creating efficient convection currents that minimize energy loss without requiring additional mechanical components or complex control systems

This design improves heating efficiency by minimizing heat dissipation and ensuring uniform heating of food surfaces, reducing energy wastage and shortening cooking time.
Implementation Method 1
a heating assembly adapted to generate heat for heating the cavity
Implementation Method 2
the hot air flow formed by the heat generated from the heating assembly could be guided downwardly by the top wall surface of the front section of the cavity to flow back to the heat source

AI summary
A kiln including a stove and a heat source wherein the stove includes a cavity, an entry, and an air outlet. The cavity includes a front section communicating with the entry, a rear section disposed away from the entry, and a middle section disposed between the front section and the rear section. A top wall surface of the front section tilts downwardly toward the entry, and a top wall surface of the rear section tilts downwardly from the middle section toward a direction away from the entry. The air outlet is located between a top of the front section and the entry. The heat source is disposed in the rear section and includes a heating assembly for generating heat. The heating assembly is located at a position higher than a half of a distance between a top and a bottom of the middle section of the cavity.
