Induction Cooking Appliance Sensor Holder for Stable Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction heating cooking appliances face issues with temperature sensor accuracy due to varying contact with the cover plate, risk of damage from impacts, and complex assembly processes for temperature sensors and fuses, which can lead to malfunction or disconnection.
Innovation Solution
A holder is integrated with a supporter to elastically support the temperature sensor and fuse, ensuring reliable contact and reducing impact, while integrating sensor and fuse assembly to simplify the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the degree of contact between the temperature sensor and the cover plate is increased, then the accuracy of the temperature measurement is improved, but the risk of damage to the temperature sensor or cover plate due to impact increases
Solution Approach 1:
The patent introduces a temperature sensor holder as an intermediary component between the temperature sensor and the cover plate. The holder includes a receiving hole that accommodates the temperature sensor and positioning protrusions that contact the cover plate, thereby mediating the contact force and protecting both the sensor and cover plate from direct impact damage while maintaining measurement accuracy.
Solution Approach 2:
The holder structure provides beforehand cushioning by absorbing impact forces before they reach the temperature sensor. The positioning protrusions on the holder contact the cover plate first, cushioning the impact and preventing direct transmission of force to the fragile temperature sensor, thus reducing damage risk while maintaining stable contact for accurate measurement.
2Reliability
If the degree of contact between the temperature sensor and the cover plate is lowered, then the risk of damage is reduced, but the accuracy of the temperature measurement is lowered
Solution Approach 1:
The holder acts as an intermediary that maintains optimal contact pressure between the positioning protrusions and the cover plate surface. This mediation ensures sufficient contact for accurate temperature measurement while preventing excessive force that could cause damage, effectively resolving the trade-off between measurement accuracy and damage risk.
3Reliability
If separate mounting structures are provided for the temperature sensor and fuse, then each component can be independently secured, but the number of assembly processes increases
Solution Approach 1:
The patent merges the mounting structures for the temperature sensor and fuse into a single integrated holder. The holder contains both a receiving hole for the temperature sensor and a receiving groove for the fuse, allowing both components to be mounted simultaneously in one assembly operation, thereby reducing the number of assembly processes while maintaining secure mounting of both components.
Solution Approach 2:
The holder serves multiple functions: it mounts the temperature sensor, mounts the fuse, provides positioning against the cover plate, and protects both components. This multi-functionality eliminates the need for separate mounting structures and reduces assembly complexity while ensuring reliable securement of both the sensor and fuse.

Implementation Method 1
at least one holder being coupled to the induction heating element, the holder comprises a receiving hole being open toward the cover plate, and a sensing portion inserted into the receiving hole and having at least a portion that protrudes from the holder toward the cover plate
Implementation Method 2
The basic heating principle of the induction heating cooking appliance is that food items contained in a container is cooked by induction heating of the cooking container; The cooking container includes a magnetic substance, wherein a current is applied to a heating coil
Implementation Method 3
The working coil may form a magnetic field using a current flowing through the working coil. The magnetic field may generate heat in the cooking container itself, which is an object to be heated, placed on the cover plate by the induction heating
