Adjustable Ejector Pipe Mounting for Gas Fireplace Flame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas fireplaces face installation challenges due to fixed ejector pipe connections, leading to potential misalignment and skewed flame combustion effects caused by manufacturing errors and inaccuracies in burner and simulated solid fuel positioning.
Innovation Solution
A movably installed ejector pipe system for gas fireplaces, featuring a nozzle, ejector pipe, limit seat, flexible sealing ring, and substrate with a stepped inner bore structure, allowing adjustable positioning and easy maintenance, along with a sealing gasket for air intake optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed connection structure is used between the ejector pipe and the nozzle, then the installation process is simplified, but manufacturing errors and welding distortion cause misalignment and skewed flame combustion
Solution Approach 1:
The ejector pipe is designed with a movable connection structure that allows adjustment of its position and angle relative to the nozzle. The pipe can rotate and tilt within a certain range, enabling operators to compensate for manufacturing errors and achieve proper alignment for optimal flame combustion, while still maintaining a relatively simple installation process.
2Stability of the object's composition
If the ejector pipe is fixedly connected to the nozzle, then the structural stability is improved, but the inability to adjust position causes error offset and installation difficulties
Solution Approach 1:
The connection structure provides dynamic adjustability during installation, allowing the ejector pipe to be positioned and angled correctly. Once installed, the structure maintains stability to preserve the optimized configuration. This dynamic-to-static transition resolves the contradiction between structural stability and installation ease.
Solution Approach 2:
The connection structure is divided into separate components including the nozzle, ejector pipe, and adjustment mechanisms. This segmentation allows independent positioning and adjustment of each component, making installation easier while maintaining overall structural stability when assembled.
3Ease of manufacture
If the ejector pipe and nozzle are installed in a fixed relative positional relationship, then the manufacturing process is simplified, but the simulated solid fuel placement becomes inaccurate affecting flame combustion
Solution Approach 1:
The movable ejector pipe allows for post-manufacturing adjustment of the fuel placement position. Even if the simulated solid fuel is initially placed with some inaccuracy, the ejector pipe can be adjusted to achieve the correct relative positioning for optimal flame combustion, thereby compensating for manufacturing tolerances.

AI summary
Disclosed in the present disclosure is a movably installed ejector pipe for a gas fireplace, the nozzle and the limit seat are fixed to the substrate, the ejector pipe is inserted between the limit seat and the nozzle, the limit seat is provided inside with a first inner bore and a second inner bore of a stepped shape, the first inner bore is below the second inner bore and is larger than the second inner bore, a head of the ejector pipe is provided with a groove. In the gas fireplace provided in the present disclosure, because a limit seat is added, the ejector pipe can swing at a certain angle within the limit seat, so that a placing angle of a burner can be finely adjusted and thereby the burner is in a position that allows for the optimal viewing effect of flame combustion.
