The control box 106 is electrically connected to the cleaning agent machine 208, the blower 209, the driving motor 305, the liquid sensor 104 and the electromagnetic valve respectively.

[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 blower 209, the driving motor 305, the liquid sensor 104 and the electromagnetic valve respectively. The staff can set parameters such as the cleaning mode and cleaning time through the control box 106. The control box 106 first conducts a system self-check to check whether the working states of the cleaning agent machine 208, the blower 209, the driving motor 305, the liquid sensor 104 and the electromagnetic valve are normal; 2) The cleaning agent machine 208 injects the charged cleaning agent through the liquid injection port. The charged cleaning agent enters the first water pipe 204 and the second water pipe 205 through the retractable hose 210. The blower 209 is started, and air is sent into the first water pipe 204 and the second water pipe 205 through the retractable hose 210 to provide air flow support for the subsequent cleaning process; 3) The drive motor 305 starts, the drive gear 307 meshes with the rack 308, driving the connecting shaft 306 to rotate. The connecting shaft 306 is fixedly connected to the rotating shaft 202, and the rotating shaft 202 drives the lever 203 to rotate. During the rotation of the lever 203, it contacts the first stop block 206 and the second stop block 207 respectively, pushing the first water pipe 204 and the second water pipe 205 to move within the cleaning box 201; 4) The cleaning box 201 slides stably on the cabinet door 102 through the stable slider 219 and the stable chute 220. The horizontal nozzles 211 and the vertical nozzles 212 on the first water pipe 204 and the second water pipe 205 start to spray the cleaning agent and air flow. The horizontal nozzles 211 maintain the connection with the inner top surface of the cleaning box 201 through the tension spring 213 to ensure the stability of the nozzles during operation. The first water pipe 204 rotates within the cleaning box 201 through the rotating bearing 214, and the second water pipe 205 expands and contracts within the cleaning box 201 through the movable sleeve 215 and the spring 216 to ensure that the nozzles can cover all corners inside the cabinet 100. The guide block 218 penetrates the side wall of the cleaning box 201 and is slidably connected thereto to ensure the stability of the second water pipe 205 during movement. The wastewater and cleaning agent generated during the cleaning process are collected through the water collecting trough 103 at the bottom of the inner cavity of the cabinet 100; 5) The liquid sensor 104 detects the liquid level in the water collecting trough 103. When the liquid level reaches a certain height, the liquid sensor 104 sends a signal to the control box 106, and the control box 106 controls the solenoid valve to open, and the drain pipe 105 discharges the wastewater in the water collecting trough 103 outside the cabinet 100; 6) After the cleaning is completed, the drive motor 305 rotates in reverse, the drive gear 307 meshes with the rack 308, driving the connecting shaft 306 to rotate in reverse, and the cleaning box 201 returns to the initial position. The control box 106 closes the cleaning agent machine 208, the blower 209 and the drive motor 305; 7) When the cleaning process ends, the staff regularly replenishes the cleaning agent into the cleaning agent machine 208 through the liquid injection port, and regularly checks the working status of the cleaning unit, the drive unit, the water collecting trough 103 and the 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, the blower 209, the drive motor 305, the liquid sensor 104 and the solenoid valve in real time, and alarms in time when a fault is found. The user troubleshoots according to the prompts of the control box 106 and contacts professional personnel for maintenance if necessary.
