Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating apparatuses face challenges with air accumulation in fuel pumps and supply pipes, leading to difficulty in igniting fuel due to air blockages, which causes inconvenience and unpleasant odors from fuel falling outside during preheating.
Innovation Solution
A method for controlling a heating apparatus that involves a passage opening process to discharge air through a discharge valve, followed by preheating of the fuel injection part, and the use of a blowing fan to introduce external air, ensuring efficient fuel transfer and ignition while preventing fuel from falling during preheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the oil pump operates to exhaust air through the nozzle before ignition, then air in the fuel supply system is removed, but repeated ignition attempts are required causing inconvenience and odor
Solution Approach 1:
The system performs a preliminary air exhaust operation by opening the discharge valve before the main ignition process. The controller detects air presence in the fuel supply pipe and activates the discharge valve to exhaust air through the heating pipe before attempting ignition, thereby eliminating the need for repeated ignition attempts and improving operational convenience.
2Reliability
If the discharge valve is opened to exhaust air from the fuel supply pipe, then air blockage is removed, but fuel may fall outside during preheating causing odor
Solution Approach 1:
The system uses the heating pipe as an intermediary pathway for air exhaust. Instead of directly exhausting air from the fuel supply pipe to the outside environment, the air is guided through the heating pipe where it can be contained and directed to appropriate discharge points, preventing fuel from falling outside and reducing odor issues.
Solution Approach 2:
The system utilizes pneumatic pressure differentials created during the discharge valve operation to control fuel flow. By carefully managing the pressure conditions during air exhaust, the system prevents fuel from being forced outside through the nozzle while still effectively removing air from the fuel supply line.
3Productivity
If preheating is performed to enable smooth fuel injection, then fuel injection is improved, but fuel may fall through the nozzle and cause odor
Solution Approach 1:
The system performs preliminary air exhaust operations before initiating preheating. By removing air from the fuel supply pipe and heating pipe in advance, the system ensures that only fuel remains in the system during preheating, eliminating the risk of fuel falling outside due to air displacement during the preheating process.

AI summary
Provided is a method for controlling a heating apparatus. A method for controlling preheating of a heating apparatus, in which a fuel tank and a fuel injection part are provided in a first passage that provides a moving path, and fuel remaining in the first passage moves in a second direction opposite to a first direction while preheating a fuel injection part, which injects the supplied fuel in the first direction, before ignition, includes a passage opening process of allowing the first passage to communicate with the outside through a discharge valve provided in the first passage, and a preheating process of heating at least a portion of the fuel injection part before the fuel injected from the fuel injection part is ignited.
