Solution Overview
Problem
Existing cooking devices with hood functions face inefficiencies in air suction due to long distances between fan motors and openings, leading to degraded suction performance and limited installation and maintenance flexibility, as well as ineffective ventilation of contaminated air from gas oven ranges.
Innovation Solution
A cooking device incorporating a ventilation apparatus with a swirler and driving motor to enhance air introduction and suction performance, featuring a movable member to block rising contaminated air and a filter unit for improved airflow guidance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a long exhaust pipe is used to install the driving part in the exhaust pipe, then the driving part can be installed, but the installation position is limited and repair and replacement become difficult
Solution Approach 1:
The exhaust pipe is divided into a first exhaust pipe and a second exhaust pipe that can be independently assembled and disassembled. The driving part is installed in the first exhaust pipe, which can be detached from the second exhaust pipe, enabling easy maintenance and replacement without requiring complete disassembly of the entire exhaust system.
Solution Approach 2:
The exhaust pipe system is designed with movable and detachable connections, transforming from a fixed rigid structure to a dynamic configurable system. This allows the driving part to be accessed, removed, and replaced by simply detaching the first exhaust pipe from the second exhaust pipe.
2Productivity
If the swirler and driving motor are added to enhance air suction performance, then air introduction efficiency improves, but device height increases
Solution Approach 1:
The swirler is designed with wings arranged in a radial pattern around a central axis, creating a three-dimensional vortex structure. This radial configuration allows the swirler to generate effective air suction and swirling motion without requiring additional vertical height, as the airflow manipulation occurs in the horizontal plane rather than extending the device vertically.
3Ease of manufacture
If the fan motor assembly is positioned far from the opening part, then installation is easier, but suction force is lost during transfer and suction performance degrades
Solution Approach 1:
The exhaust pipe is designed with a curved configuration rather than a straight line, allowing the driving part to be positioned closer to the opening part while maintaining ease of installation. The curved path optimizes airflow direction and reduces energy loss, ensuring that suction force is effectively transmitted from the fan motor assembly to the opening part without significant degradation.

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 solution enhances air suction efficiency, reduces device height, and facilitates easier maintenance by improving airflow patterns and preventing contaminated air from spreading in the kitchen, thus maintaining a cleaner environment.
Implementation Method 1
