Cooking Appliance Venting Cap Layout for Dual Cooking Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooking appliances with a single venting passage struggle to accommodate both baking and conventional cooking modes, as they require different venting needs, making it difficult to achieve compatible venting modes for efficient cooking.
Innovation Solution
A cooking appliance design featuring a venting passage on the appliance cover, a baking assembly, and a detachable venting cap that switches positions to manage air flow, allowing for simultaneous air admission and venting during baking and rapid air venting during conventional cooking, ensuring improved efficiency and stability in both modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single venting passage is used in the cooking appliance, then the device complexity is reduced, but the adaptability to different cooking modes (baking and conventional cooking) deteriorates
Solution Approach 1:
The venting cap is designed to be movable between two positions: a first position where it blocks the venting passage for conventional cooking, and a second position where it allows venting for baking mode. This dynamic repositioning enables a single venting passage to accommodate different cooking mode requirements without increasing device complexity
Solution Approach 2:
The single venting passage is designed to serve multiple functions by combining it with a movable venting cap. The same passage can be used for both blocking (conventional cooking) and venting (baking mode), making the venting system universal for different cooking modes rather than requiring separate passages for each mode
2Object-affected harmful factors
If the venting cap blocks the venting passage during conventional cooking, then the humidity accumulation is reduced, but the air circulation required for baking is restricted
Solution Approach 1:
The venting cap is dynamically positioned to block the venting passage during conventional cooking, preventing humid air from entering and accumulating inside the appliance body. During baking mode, the cap is repositioned to allow air circulation. This dynamic blocking/allowing mechanism resolves the contradiction between preventing humidity accumulation and enabling air circulation
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
The design enhances baking efficiency by prolonging air circulation and ensures stable conventional cooking by effectively managing air flow, reducing the risk of humidity and oily waste accumulation, thereby improving user experience and appliance safety.
Implementation Method 1
the venting cap is assembled at a bottom end of the venting passage when the inner lid is dismounted, and the venting cap is assembled at a top end of the venting passage after the inner lid is mounted
Implementation Method 2
the appliance body being provided with a heating structure
Implementation Method 3
hot air needs to be vented out directly

AI summary
A cooking appliance comprises an appliance cover (1), an appliance body (2) and an inner lid (3), the appliance cover (1) being coveringly arranged above the appliance body (2) in a closable and openable manner; the appliance body (2) being provided with a heating structure. The appliance cover (1) comprises a cover body (4), a baking assembly (5) and a venting cap (7), the cover body (4) being provided with a venting passage (6) through which the inside of the cooking appliance communicates with the outside, the inner lid (3) being detachably mounted to the cover body (4); the baking assembly (5) being arranged below the cover body (4), the inner lid (3) being located below the baking assembly (5) when mounted to the cover body (4); the venting cap (7) being detachably mounted at any one end of the two ends of the venting passage (6), wherein the venting cap (7) is assembled at a bottom end of the venting passage (6) when the inner lid (3) is dismounted, and the venting cap (7) is assembled at a top end of the venting passage (6) after the inner lid (3) is mounted. The cooking appliance can solve the problem that two venting modes are incompatible.
