Cooking Chamber Airflow Guide to Block Upward Heat Escape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heating cooking apparatus allows warm air to flow out of the heating cooking chamber when the opening is opened, causing an unpleasant experience for the user.
Innovation Solution
A heating cooking apparatus with a heating cooking chamber, a housing, a lid portion, a first circulation portion, a first blow-out port, and a guide portion, where the first air is circulated between the upper wall of the chamber and the housing, blown out from the first blow-out port, and guided toward the opening when the lid opens, inhibiting air from flowing out upward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid portion opens the opening of the heating cooking chamber, then the user can access the chamber, but warm air flows out in the upward direction causing unpleasant experience
Solution Approach 1:
The guide portion acts as an intermediary structure that intercepts and redirects the warm air flow. It is positioned between the chamber opening and the user, capturing the upward-flowing warm air and directing it along the upper wall away from the user's face, thus mediating the harmful air flow effect
Solution Approach 2:
The air flow direction is changed from a vertical upward path toward the user to a horizontal path along the upper wall. The guide portion creates a new flow dimension that moves air laterally across the top of the chamber rather than allowing it to rise directly outward toward the user
2Productivity
If the first circulation portion blows out first air from the first blow-out port, then air circulation is improved, but the complexity of the device increases
Solution Approach 1:
The first circulation portion is integrated into the existing housing structure and works in conjunction with the guide portion to serve multiple functions: it circulates air within the chamber, directs air flow away from the user, and maintains pressure balance. This multi-functional design improves air circulation efficiency without proportionally increasing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively inhibits air from the heating cooking chamber from flowing out in the upward direction when the opening is opened, improving user comfort by preventing warm air from escaping.
Implementation Method 1
The first circulation portion causes first air to circulate between an upper wall of the heating cooking chamber and an upper wall of the housing
Implementation Method 2
The guide portion guides, toward the opening, the first air blown out from the first blow-out port when the lid portion opens the opening

AI summary
A heating cooking apparatus includes a heating cooking chamber, a housing, a lid portion, a first circulation portion, a first blow-out port, and a guide portion. The heating cooking chamber further includes an opening. The housing accommodates the heating cooking chamber. The lid portion opens and closes the opening. The first circulation portion causes first air to circulate between an upper wall of the heating cooking chamber and an upper wall of the housing. When the lid portion opens the opening, the guide portion guides the first air blown out from the first blow-out port toward the opening.
