The drain pipe 105 passes through the cabinet 100 and extends to its exterior. A control box 106 is fixedly installed on the outer wall of the cabinet 100. The control box 106 is electrically connected to the cleaning agent machine 208, the fan 209, the drive motor 305, the liquid sensor 104, and the electromagnetic valve.

[0025] Working principle and process: 1) The staff starts the self-cleaning program through the control box 106. The control box 106 is electrically connected to the cleaning agent machine 208, the fan 209, the drive motor 305, the liquid sensor 104 and the solenoid valve respectively. The staff can set parameters such as cleaning mode and cleaning time through the control box 106. The control box 106 first performs a system self-test to check whether the working status of the cleaning agent machine 208, the fan 209, the drive motor 305, the liquid sensor 104 and the solenoid valve is normal. 2) The cleaning agent machine 208 injects the electrified cleaning agent through the injection port. The electrified cleaning agent enters the first water pipe 204 and the second water pipe 205 through the retractable hose 210. The fan 209 starts and sends air into the first water pipe 204 and the second water pipe 205 through the retractable hose 210 to provide airflow support for the subsequent cleaning process. 3) The drive motor 305 starts, the drive gear 307 meshes with the rack 308, and drives the connecting shaft 306 to rotate. The connecting shaft 306 is fixedly connected to the rotating shaft 202. The rotating shaft 202 drives the lever 203 to rotate. During the rotation, the lever 203 contacts the first stop 206 and the second stop 207 respectively, pushing the first water pipe 204 and the second water pipe 205 to move inside the cleaning box 201. 4) The cleaning box 201 slides stably on the cabinet door 102 via the stabilizing slider 219 and the stabilizing slide groove 220. The horizontal nozzle 211 and the vertical nozzle 212 on the first water pipe 204 and the second water pipe 205 begin to spray cleaning agent and airflow. The horizontal nozzle 211 is kept connected to the inner top surface of the cleaning box 201 by the tension spring 213 to ensure that the nozzle remains stable during operation. The first water pipe 204 rotates in the cleaning box 201 via the rotating bearing 214. The second water pipe 205 extends and retracts in the cleaning box 201 via the movable sleeve 215 and the spring 216 to ensure that the nozzle can cover all corners inside the cabinet 100. The guide block 218 penetrates the side wall of the cleaning box 201 and slides thereto to ensure that the second water pipe 205 remains stable during movement. The wastewater and cleaning agent generated during the cleaning process are collected through the water collection tank 103 at the bottom of the inner cavity of the cabinet 100. 5) Liquid sensor 104 detects the liquid level in water collection tank 103. When the liquid level reaches a certain height, liquid sensor 104 sends a signal to control box 106. Control box 106 controls the solenoid valve to open, and drain pipe 105 discharges the wastewater in water collection tank 103 to the outside of cabinet 100. 6) After cleaning is completed, the drive motor 305 reverses, the drive gear 307 meshes with the rack 308, driving the connecting shaft 306 to reverse, the cleaning box 201 returns to the initial position, and the control box 106 shuts down the cleaning agent machine 208, the fan 209 and the drive motor 305. 7) After the cleaning process is completed, the staff will regularly replenish the cleaning agent to the cleaning agent machine 208 through the liquid injection port, and regularly check the working status of the cleaning unit, drive unit, water collection tank 103 and drain pipe 105 to ensure the normal operation of the system. The control box 106 monitors the working status of the cleaning agent machine 208, fan 209, drive motor 305, liquid sensor 104 and solenoid valve in real time. If a fault is found, an alarm will be set in time. The user will troubleshoot according to the prompts of the control box 106, and contact professional personnel for maintenance if necessary.
