Oven Door Rotary Hinge for Switchable Pull-Down and Side-Swing Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven doors, either pull-down or side-swing, face issues such as user interference, inconvenient food placement, and difficulty for disabled users, children, and elderly individuals in carrying heavy food due to lack of versatility in opening types.
Innovation Solution
An oven with a rotary hinge system that allows the door to rotate in multiple directions, enabling users to easily switch between pull-down and side-swing modes using an operation unit, incorporating a first link moving in one direction and a second link moving perpendicular to it, allowing the door to open/close the cooking space selectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pull-down type door is used, then the door can provide a temporal shelve function, but it interferes with the user when open and makes food placement and cleaning inconvenient
Solution Approach 1:
The door hinge system allows dynamic switching between pull-down mode (providing temporal shelve function) and side-swing mode (providing convenient food placement). The hinge can rotate to change the door's opening direction, enabling the system to adapt between two functional states based on user needs.
2Ease of operation
If a side-swing type door is used, then user interference is reduced and food placement is convenient, but it cannot provide the temporal shelve function and is difficult for disabled users, children, and elderly to handle heavy food
Solution Approach 1:
The hinge system enables dynamic mode switching, allowing the door to function as a side-swing door for convenient food placement, and can be rotated to provide pull-down functionality with temporal shelve support when needed.
3Device complexity
If a fixed door hinge is used, then the structure is simple, but the door cannot be opened in multiple directions and lacks versatility
Solution Approach 1:
The hinge assembly includes a hinge body with a rotating member that can rotate between a first position (side-swing mode) and a second position (pull-down mode). This rotational capability allows the door to change opening directions while maintaining a relatively compact hinge structure.

AI summary
The present invention provides an oven including: a cabinet having a cooking space open forward; a door rotating to open/close the cooking space; and a rotary hinge disposed on the front of the cabinet to rotate the door in various directions, in which the door includes: a first ink moving in a first direction; and a second link moving in a second direction perpendicular to the first direction by movement of the first link, and the rotational direction of the door depends on movement of the first link.
