Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-stage stacked ovens face challenges in cooling electric parts and water tanks due to increased temperature and limited space, as well as difficulties in door opening mechanisms, particularly with pull-down doors requiring additional space.
Innovation Solution
The implementation of a supporter system that allows for vertical stacking of ovens with different cooking methods, incorporating turbo fans for air circulation to cool components and a door design that maintains airflow paths even when closed, reducing overall height and enhancing cooking chamber size.

1Length of stationary object
If electric parts and water tanks are installed in the upper space of the cavity in a two-stage stacked oven, then the overall height is reduced, but the cooling of these components becomes problematic due to high temperature and limited space
Solution Approach 1:
The cavity space is segmented into multiple regions: the upper space for component installation, the lower cooking chamber for heating, and dedicated airflow channels for cooling. This segmentation allows simultaneous achievement of compact height and effective cooling by creating separate functional zones within the stacked oven structure.
Solution Approach 2:
Airflow channels act as intermediary pathways that connect the lower cooking chamber to the upper component installation space. These channels mediate the transfer of cool air from the lower chamber to cool the electric parts and water tanks in the upper space, solving the cooling problem without increasing overall height.
2Ease of operation
If a pull-down door is used in the stacked oven, then door opening functionality is achieved, but additional space at the lower portion is required which increases overall height
Solution Approach 1:
The door mechanism transitions from a static pull-down design requiring large clearance to a dynamic hinge-based swing door that rotates within a compact arc. This dynamic movement allows the door to open and close effectively within the limited space of the stacked oven configuration, eliminating the need for additional lower space.
Solution Approach 2:
The door opening motion is changed from vertical displacement (pull-down) to rotational movement (swing) in a different dimensional plane. This dimensional change allows the door to achieve full opening functionality without requiring additional vertical space at the lower portion, thus maintaining compact overall height.

Function Achieved in This Case
This solution ensures effective cooling of components and maintains door functionality while minimizing the overall height of the stacked oven, providing a larger cooking chamber and efficient airflow for both ovens.
Implementation Method 1
the air which flows down from the lower portion of the first oven is introduced into the upper space of the first oven through the airflow path

AI summary
A stacked oven may include a supporter installed between a first oven at a lower portion of the first oven and a second oven above the first oven and fixing the second oven at a position spaced apart upward from the first oven. The supporter may include a first installation member that includes a vertical extending member that contacts a side surface of the first oven, a lateral extending member that extends from an upper portion of the vertical extending member in a direction toward a center of the first oven, and a load support provided between a lower portion of the lateral extending member and the first oven; a second installation member that includes a lower surface support and a side surface support that contact a lower surface and a side surface of the second oven, respectively, and having an angle with respect to each other, and a guide that extends upward and outward from an upper end of the side surface support; and a connection member that vertically connects the lateral extending member and the lower surface support.
