Solution Overview
Problem
Microwave ovens with air frying functions experience inadequate and uneven hot air flow, leading to inconsistent food coloring, cooked and rare food, and partial burning, making accurate temperature control challenging.
Innovation Solution
A cooking device with a gas circulation apparatus that drives gas to flow in multiple directions, increasing heat convection generation area and intensity, ensuring an even temperature field and accurate temperature monitoring for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional gas circulation apparatus is used in a microwave oven with air frying function, then the device can provide hot air circulation, but the hot air flow is inadequate and uneven, resulting in inconsistent food coloring, presence of cooked and rare food, and partial burning
Solution Approach 1:
The gas driving part is divided into multiple fan blade parts (first fan blade part, second fan blade part, etc.) that are spatially separated and oriented in different directions. Each fan blade part generates independent gas flow patterns, collectively creating comprehensive and uniform hot air circulation throughout the cooking cavity, thereby resolving the uneven heating issue
Solution Approach 2:
Different fan blade parts are positioned at specific locations (e.g., upper, lower, left, right sides) and oriented to direct gas flow toward specific regions of the cooking cavity. This localized flow control ensures that each region receives adequate and appropriately directed hot air, achieving uniform temperature distribution and consistent food cooking across the entire cavity
2Productivity
If the gas circulation is inadequate, then energy consumption is reduced, but the heat convection generation area and intensity are insufficient, leading to poor cooking quality and inaccurate temperature control
Solution Approach 1:
The fan blade parts are arranged in three-dimensional space with different orientations (horizontal, vertical, inclined angles). This spatial arrangement creates multi-directional gas flow patterns that thoroughly permeate the cooking cavity, significantly increasing the heat convection generation area and intensity, thereby improving both cooking efficiency and temperature control precision

AI summary
A cooking device is provided. The cooking device including: a housing having a cooking cavity; and a gas circulation apparatus disposed in the housing and configured to drive gas in the cooking cavity to flow and circulate. The gas circulation apparatus includes a gas driving part. When driven by the gas driving part, gas has a first part flowing in a first direction and a second part flowing in a second direction, one of the first direction and the second direction is a circumferential direction of the gas driving part, and another of the first direction and the second direction is a radial direction of the gas driving part.
