Automatic Welding for Efficient Refrigerator Pipe Assembly
Here’s PatSnap Eureka !
Summary
Problems
In traditional refrigerators, the limited space in the machine room makes direct pipe welding difficult and time-consuming, leading to increased costs and potential assembly errors due to the need for manual welding and cramped working conditions.
Innovation solutions
The implementation of automatic high-frequency welding using a connection pipe with a pre-connected connection member, which is inserted into the sealing pipe to a specific length and welded in place, preventing excessive insertion and ensuring accurate positioning, thereby reducing manual labor and assembly errors.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If manual welding is performed in the limited machine room space, then pipe connection is achieved, but the number of work steps increases and assembly time is lost
Why choose this principle:
The patent replaces manual mechanical welding operations with an automatic high-frequency welding system. The welding rod is automatically fed through the connection pipe to the sealing pipe, and high-frequency current automatically performs the welding operation, eliminating the need for manual welding steps and significantly reducing assembly time.
Principle concept:
If manual welding is performed in the limited machine room space, then pipe connection is achieved, but the number of work steps increases and assembly time is lost
Why choose this principle:
The connection pipe structure enables self-positioning and self-alignment during insertion into the sealing pipe. The welding rod automatically positions itself through the connection pipe, and the high-frequency welding system automatically performs the connection without requiring manual positioning or adjustment, making the process self-service and eliminating unnecessary work steps.

Abstract
A refrigerator includes a cabinet configured to define a storage space and a machine room which is separated from the storage space in the cabinet. A compressor, a condenser, and a cooling fan are configured to cool the storage space and disposed in the machine room. The compressor includes a shell configured to define an outer appearance of the compressor, a sealing pipe connected to the shell to inject a refrigerant into the shell, and a connection pipe connected to the sealing pipe. The connection pipe includes a body portion connected to the sealing pipe and a connection member passing through the body portion and welded to an end of the sealing pipe in a state of being in contact with the end of the sealing pipe when the body portion is inserted into the sealing pipe.
