Description

Technical Field

[0001] This application relates to the field of kitchen disinfection equipment technology, and in particular to a guide rail routing structure for a disinfection cabinet. Background Technology

[0002] In the field of existing kitchen disinfection equipment technology, especially in the design of disinfection cabinets, the installation and stability of the inner rails have always been key technical challenges. Most switches in existing disinfection cabinets are magnetic induction proximity switches, which control the power supply to the light source inside the cabinet by sensing the distance between the magnet and the proximity switch. The installation of the inner rails in traditional disinfection cabinet drawers often uses a distributed component assembly method, especially the dispersed arrangement of control wires. This not only increases installation complexity and errors but may also lead to damage to the control wires over long-term use, affecting the smooth sliding of the drawers and the overall stability of the disinfection cabinet. Therefore, the wiring structure of disinfection cabinet guide rails in related technologies has the drawbacks of being difficult to install due to its dispersed arrangement and the susceptibility of control wires to damage over long-term use. Utility Model Content

[0003] To avoid the aforementioned drawbacks, a guide rail wiring structure for a disinfection cabinet is provided.
