Solution Overview
Problem
Existing cooking appliances have complex and troublesome structures for installing and disassembling temperature sensors, requiring separate components for spring support, vertical guidance, and anti-separation mechanisms, making maintenance difficult.
Innovation Solution
A modular sensor structure with a spring-mounted sensor module that uses keys and key grooves for anti-separation, integrated with a piston ring for upward/downward movement guidance, simplifying assembly and disassembly by preventing the sensor module from separating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components for spring support, vertical guidance, and anti-separation mechanisms are used, then the temperature sensor can be installed, but the structure becomes complex and maintenance becomes difficult
Solution Approach 1:
The patent combines multiple separate components (spring support structure, vertical guidance structure, and anti-separation structure) into a single integrated temperature sensor assembly. The spring support structure includes both the anti-separation protrusion and the vertical guidance groove, eliminating the need for separate components and simplifying the overall structure while maintaining reliable temperature sensor installation.
2Reliability
If separate components for spring support, vertical guidance, and anti-separation mechanisms are used, then the temperature sensor can be installed, but maintenance becomes troublesome
Solution Approach 1:
The patent integrates the spring support structure, vertical guidance structure, and anti-separation structure into a unified component assembly. This merging allows the temperature sensor to be installed and maintained as a single unit, significantly improving ease of repair by eliminating the need to handle multiple separate components during maintenance operations.
3Reliability
If multiple separate structures are used for sensor installation, then the sensor can be secured, but assembly becomes troublesome
Solution Approach 1:
The patent combines the spring support structure with anti-separation protrusions and vertical guidance grooves into a single integrated component. This merging simplifies the assembly process by reducing the number of parts that need to be assembled while ensuring the sensor remains securely positioned through the combined anti-separation and guidance features.

AI summary
Disclosed herein is a cooking appliance. A working coil provided at a lower portion of the cooking appliance. The working coil heats a tray disposed in a cooking compartment in an IH mode. A temperature measurement module, which measures a temperature of the tray in a contact mode, is provided in the center of the working coil. The temperature measurement module includes a module body that is elastically biased upward by a spring. The module body is inserted into the spring and supports upper and lower ends of the spring. When the module body is installed on the working coil, the lower end of the spring is supported by an installation base of the working coil. The module body and the installation base are fastened in a key-to-key groove structure.
