Solution Overview

Problem

Existing multifunctional air fryers have high production costs, small internal cooking space, and limited functions, unable to perform tasks like stir-frying and stewing.

Innovation Solution

An overturnable dual-purpose multifunctional air fryer design featuring a machine core with a thermal circulation fan and heating element, detachably connected to a fryer with multiple configurations allowing for various cooking modes, including deep frying, steaming, boiling, frying, roasting, and stir-frying, while optimizing space and reducing costs through innovative structural elements like thermal conductive structures and a transparent lid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a steam generator and bottom heating device are added to the air fryer to achieve multiple functions, then the cooking functions are improved, but the production cost increases and the internal cooking space decreases

Engineering Contradiction:
Improvecooking functionsVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent makes the existing heating element and fan serve multiple cooking functions by changing the orientation and configuration of the fryer basket. The same heating element performs both top-down heating (for air frying) and bottom-up heating (for steaming and boiling) functions, eliminating the need for separate heating devices and reducing production costs while expanding cooking capabilities

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an overturnable fryer basket that can be flipped to change the heating direction. By inverting the fryer basket orientation, the heating element transitions from top-down to bottom-up heating mode, enabling steaming and boiling functions without adding extra equipment, thus avoiding increased production costs

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If a steam generator and bottom heating device are added to the air fryer to achieve multiple functions, then the cooking functions are improved, but the internal cooking space becomes smaller

Engineering Contradiction:
Improvecooking functionsVSAvoidinternal cooking space
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent makes the existing heating element and fan serve multiple cooking functions by changing the orientation and configuration of the fryer basket. The same heating element performs both top-down heating (for air frying) and bottom-up heating (for steaming and boiling) functions, eliminating the need for separate heating devices and reducing production costs while expanding cooking capabilities

3Adaptability or versatility

If the machine core and fryer are detachably connected with overturnable configuration, then the multifunctionality and space optimization are improved, but the device complexity increases

Engineering Contradiction:
ImprovemultifunctionalityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the air fryer into two detachable modules: a machine core (containing the motor and fan) and a fryer basket (containing the heating element). This segmentation allows the components to be independently manufactured and assembled, simplifying the overall structure while enabling multiple cooking functions through different configurations and orientations of the detachable parts

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure provides an overturnable dual-purpose multifunctional air fryer, including a machine core and a fryer, wherein the machine core has a bottom opening which is provided with a thermal circulation fan and a heating element therein, and the fryer has a top opening; and the machine core and the fryer are detachably connected, and the machine core and the fryer can be in: a first matching state, where the machine core is located above the fryer, and the bottom opening of the machine core faces downward and communicates to the top opening of the fryer; and a second matching state, where the fryer is located above the machine core, and the bottom opening of the machine core faces upward and connects to a bottom of the fryer. According to the structural design of the air fryer in the present disclosure, the machine core may be overturned to work so that the air fryer has multiple functions such as deep frying, steaming, boiling, frying, roasting, stewing, stir-frying, etc.; and thus, the requirements of different users can be meet, and the practicability of the air fryer can be greatly increased. In addition, the air fryer, in the present disclosure, has relatively larger cooking space and lower manufacturing costs by removing the elements such as the door panel, the lower shell, etc.
