Upper Core Venting Structure for Air Fryer Moisture Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air fryers face challenges in efficiently removing water vapor from the cooking pot, which affects cooking performance and taste.
Innovation Solution
The upper machine core device includes a ventilation member with a ventilation channel that connects to the cooking cavity, allowing water vapor to be smoothly discharged outside, thereby adjusting the water vapor content and improving cooking taste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air fryer uses a heating tube and fan to circulate hot air for cooking, then the cooking effect is improved, but water vapor accumulates in the pot body affecting cooking quality
Solution Approach 1:
The patent extracts the water vapor removal function from the heating system by adding a separate exhaust assembly. The exhaust assembly includes an exhaust channel that penetrates the machine core shell and an exhaust fan that actively draws water vapor out of the cooking cavity, separating the heating/circulation function from the moisture removal function to improve cooking quality
Solution Approach 2:
The patent introduces an intermediary exhaust assembly that acts as a bridge between the cooking cavity and the external environment. The exhaust fan serves as a mediator to actively transport water vapor from the cooking cavity through the exhaust channel to the outside, enabling controlled moisture removal without disrupting the hot air circulation system
2Loss of energy
If the upper machine core assembly is sealed to contain heat, then energy efficiency is improved, but water vapor cannot be removed
Solution Approach 1:
The patent segments the machine core shell into multiple sections with a selective opening. The exhaust channel is positioned at a specific location on the shell, allowing the shell to be divided into a cooking cavity portion and an exhaust portion. This segmentation enables the majority of the shell to remain sealed for heat retention while a specific segment facilitates water vapor removal
Solution Approach 2:
The patent applies local quality by creating a localized exhaust opening in the otherwise sealed machine core shell. The exhaust channel is positioned at a specific location with specific dimensions optimized for water vapor removal while minimizing heat loss. The local opening is strategically placed to allow moisture discharge without compromising overall thermal efficiency
3Object-generated harmful factors
If the ventilation channel is positioned to face the baffle member, then water vapor removal is improved, but the structure becomes more complex
Solution Approach 1:
The patent merges the ventilation channel with the exhaust fan assembly, integrating the channel directly into the fan housing structure. The exhaust fan and exhaust channel are positioned as a unified assembly that faces the baffle member, combining the air moving function with the vapor discharge pathway into a single integrated component rather than separate elements
Solution Approach 2:
The exhaust assembly serves multiple functions: the exhaust fan provides both air circulation and water vapor removal, while the exhaust channel simultaneously acts as a structural support element and a vapor discharge pathway. The baffle member serves both to direct airflow and to position the exhaust channel optimally for water vapor removal
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
This solution effectively addresses the issue of water vapor removal, enhancing the cooking performance and taste of air-fried food by maintaining optimal air pressure and moisture levels within the cooking cavity.
Implementation Method 1
The heating assembly is provided in the installation cavity
Implementation Method 2
the fan is used to blow hot air into the pot to heat the food, so that the hot air can be circulated in the pot body
Implementation Method 3
the ventilation channel is configured to pass through both sides of the ventilation member; one end of the ventilation channel is configured to face a side of the baffle member away from the installation cavity

AI summary
Disclosed are an upper machine core device and a cooking appliance. The upper machine core device includes an upper machine core assembly, a heating assembly and a ventilation member. The upper machine core assembly is provided with an installation cavity and includes a baffle member. The installation cavity forms an opening on one side of the upper machine core assembly; the baffle member is provided in the installation cavity and covers the opening. The heating assembly is arranged in the installation cavity. The ventilation member is connected to the upper machine core assembly, and is provided with a ventilation channel. The ventilation channel runs through both sides of the ventilation member, and one end of the ventilation channel faces the side of the baffle member away from the installation cavity. When the upper machine core device covers the pot body provided with the cooking cavity, the cooking cavity and the installation cavity are isolated due to the presence of the baffle member. Therefore, the ventilation member allows the ventilation channel to be connected with the cooking cavity when the upper machine core device covers the pot body; and then when the cooking appliance is in working condition, the water vapor in the pot body can be smoothly discharged to the outside through the ventilation channel, which can adjust the water vapor content in the pot to improve the cooking taste.
