Pellet Fuel Ignition Device with Covered Bottom Heater Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pellet fuel burning devices face inefficiencies in initial ignition time and uniform heat transfer due to accumulation of fuel and non-uniform heat distribution, leading to prolonged cooking times and inconvenience.
Innovation Solution
An ignition device with a heater bar at the lower part of an inner container, covered by a cover forming a space portion, ensures efficient heat supply and rapid ignition of pellet fuel by evenly distributing heat across the fuel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual ignition of accumulated fuel is used, then the device structure is simple, but the ignition time is long and convenience is poor
Solution Approach 1:
The patent replaces the manual mechanical ignition method with an electrical heating system. A heater bar equipped with a heating element is positioned at the bottom of the fuel container, converting manual ignition into automated electrical heating ignition, thereby improving operational convenience and reducing ignition time.
Solution Approach 2:
The heater bar is pre-positioned at the bottom of the container and can be activated before fuel accumulation occurs. This preliminary preparation of the heating source allows for rapid ignition when fuel is supplied, eliminating the time delay associated with manual ignition of accumulated fuel.
2Quantity of substance
If the pellet burner unit size increases, then the fuel capacity is increased, but the heat transfer becomes non-uniform and is impeded
Solution Approach 1:
The patent applies local quality by positioning the heating element specifically at the bottom region where fuel accumulates. The heater bar provides localized heating at the base, ensuring that heat is generated where fuel is most concentrated, thereby maintaining uniform heat transfer even as fuel capacity increases.
Solution Approach 2:
The heating system is segmented into a modular heater bar structure with multiple heating zones along its length. This segmentation allows different regions of the fuel container to receive appropriate heat distribution, preventing heat transfer impediment even when the container size and fuel capacity are increased.
