AI Technical Summary
The existing refrigerator drainage structure is complex, making it inconvenient to manufacture.
The drainage pipe fittings are made of one piece, with the upper and lower water guide pipes. They are fixed to the inner tank by the upper and lower flange plates. The foam layer wraps around the inner tank and extends into the compressor compartment, simplifying the structure and fixing it with glue.
It simplifies the manufacturing of drainage pipe fittings and saves materials, resulting in a simpler structure and improved production efficiency.
