Gas Water Heater Smoke Exhaust Pipe Rainproof Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke exhaust pipes for gas water heaters face challenges in mounting and rainproofing, with previous solutions either requiring difficult welding outdoors or needing a fixed positioning plate, which complicates installation and operation.
Innovation Solution
A smoke exhaust pipe design featuring a pipe body with a mounting part and a rainproof pipe with a downward opening, allowing for easy insertion and sealing, along with a movable rainproof pipe that can be conveniently mounted using hooks and notches, facilitating simple assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rainproof structure is welded to a pipe opening, then rainproof effect is improved, but mounting difficulty increases
Solution Approach 1:
The smoke exhaust pipe is divided into multiple segments including the pipe body, mounting part, and rainproof pipe that can be assembled separately. The rainproof pipe is detachably connected to the mounting part via hooks and notches, allowing the rainproof function to be integrated without requiring welding operations.
Solution Approach 2:
The mounting part is inserted into the pipe body, and the rainproof pipe is nested on the mounting part. This nested structure allows the rainproof component to be integrated into the pipe system without external welding, simplifying the mounting process while maintaining rainproof effectiveness.
2Reliability
If a positioning plate is fixed on a wall, then rainproof effect is improved, but device complexity increases
Solution Approach 1:
The rainproof function is extracted from the wall-mounted positioning plate concept and integrated directly onto the smoke exhaust pipe itself through the rainproof pipe component. This eliminates the need for separate wall fixation structures, reducing overall device complexity while maintaining rainproof performance.
Solution Approach 2:
The mounting part serves multiple functions: it connects the pipe body to the rainproof pipe, provides structural support, and enables detachable assembly. This multi-functional design eliminates the need for separate positioning plates and wall fixation components, simplifying the overall mounting structure.
