Horizontal Compressor Leg Design for Brazing Workability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horizontal compressors with a second leg that supports and stands the hermetic container face productivity issues due to the support piece hindering the brazing of the refrigerant return pipe at the joint port, increasing labor and reducing efficiency.
Innovation Solution
The second leg is designed with a first support portion that extends away from the joint port, ensuring sufficient space for brazing and integrating both support and standing functions, reducing the number of components and assembly time.

Engineering Contradiction Analysis
1Device complexity
If the support piece is integrated with the second leg to reduce component number, then the number of components and assembly labor-hours are reduced, but the support piece hinders the brazing of the refrigerant return pipe at the joint port
Solution Approach 1:
The second leg is segmented into functionally distinct portions: a support portion for standing the hermetic container and a leg portion for supporting the container in horizontal attitude. This segmentation allows the brazing portion of the joint port to be positioned away from the support piece, eliminating the hindrance to brazing work while maintaining the integrated structure's component reduction benefits.
Solution Approach 2:
Different portions of the second leg are designed with different spatial orientations and functions. The support portion extends in one direction to provide standing capability, while the leg portion extends in another direction to provide horizontal support, creating local spatial quality variations that ensure the joint port remains accessible for brazing operations.
2Loss of time
If the second leg has both support and standing functions integrated, then assembly time is reduced, but the interval between the support piece end and joint port becomes very small
Solution Approach 1:
The second leg utilizes three-dimensional spatial arrangement by extending the support portion and leg portion in different directions from the hermetic container. This dimensional differentiation creates sufficient spatial interval between the support piece end and the joint port, allowing brazing operations to proceed without interference while maintaining the integrated structure's assembly efficiency.

AI summary
According to one embodiment, a horizontal compressor comprises a container accommodating a compression mechanism unit and an electric motor unit, a first leg fixed to the container near the motor unit, a second leg fixed to an end of the container on the compression mechanism unit side, an accumulator between the legs, and a joint port in the container. The second leg includes a first support portion supporting the container in a horizontal attitude, and a second support portion supporting the container standing in a vertical attitude. The first support portion extends in a direction away from the joint port relative to the second support portion.
