Electric Oven Heater Access Layout for Safer Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric oven heaters are prone to damage during installation and removal processes, and the current methods for installing and removing heaters are inefficient.
Innovation Solution
The design includes a main body with a cooktop and a cavity where the first heating unit is installed or removed through an opened top, and the second heating unit is accessed through an open front of the cooking chamber, using a reflector with heater placement parts and a grate to protect the heaters during these processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the heater is installed or removed independently through the cooking chamber, then the heater can be accessed for maintenance, but the heater may be damaged during the process and the process is inefficient
Solution Approach 1:
The oven is divided into two separate access paths: one for the first heating unit through the top opening and another for the second heating unit through the front opening. This segmentation allows each heater to be accessed independently through its own dedicated path, preventing damage during installation and removal while improving operational efficiency
Solution Approach 2:
The patent introduces intermediate structures including a top opening mechanism and a front opening mechanism that serve as mediators between the external environment and the heating units. These intermediaries provide protected access paths, allowing heaters to be installed and removed without direct exposure to potential damage sources in the cooking chamber
2Productivity
If the heater is installed or removed through the cooking chamber, then access is possible, but the process efficiency is reduced
Solution Approach 1:
The top opening and front opening are prepared in advance as dedicated access paths. The first heating unit is positioned and secured through the top opening before cooking operations begin, and the second heating unit is positioned through the front opening. This preliminary arrangement eliminates the need for time-consuming disassembly during maintenance, significantly improving service efficiency
Solution Approach 2:
Instead of accessing both heating units through the same vertical space (cooking chamber), the patent introduces a horizontal dimension by creating a front opening alongside the vertical top opening. This dimensional change provides parallel access paths, allowing simultaneous or independent maintenance of both heating units without interfering with each other, thereby reducing total service time
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 design minimizes damage to the heaters during installation and removal and enhances the efficiency of the process by allowing for safe and convenient access through the top and front of the oven.
Implementation Method 1
a first heating unit and a second heating unit, which supply radiant energy into the cooking chamber

AI summary
Provided is an electric oven, which includes a main body, a cooktop, and an oven part. The cooktop is disposed in an upper portion of the main body to heat an object. The oven part is disposed within the main body under the cooktop, and includes a cavity including a cooking chamber, a door selectively opening and closing the cooking chamber, and a first heating unit and a second heating unit, which supply radiant energy into the cooking chamber. Before the cooktop is installed, or after the cooktop is removed, a top of the main body is opened, and the first heating unit is installed in or removed from the cavity through the opened top of the main body. The second heating unit is installed in or removed from the cooking chamber through an open front of the cooking chamber. Accordingly, a heater can be protected, and be conveniently installed and removed.
