[0053] An embodiment of a control method of an integrated multifunctional water tank control system:

[0054] A control method for an integrated multifunctional sink control system is provided, and the system is applied to the above-mentioned integrated multifunctional sink control system for control. The method comprises: setting the operation time of the integrated sink, starting the integrated multifunctional sink control system, judging whether a cutting board signal of the integrated sink is detected, and if so, starting the sterilization function, and starting the driving fan unit 8 and the PCT heating circuit 4 in turn to dry and heat the items in the storage bucket.

[0055] After running for a preset time, the fan unit 8 and the PCT heating circuit 4 are stopped, and the ultraviolet sterilization lamp is started to sterilize and disinfect.

[0056] When the power is turned on, the radar sensing circuit 6 is started, and when a human body sensing signal is detected, the LED atmosphere light is started, and the ultraviolet sterilization lamp is turned off at the same time.

[0057] During the operation of the LED atmosphere light, if no human sensing signal is detected, the LED atmosphere light will be turned off and the ultraviolet sterilization lamp will be started at the same time.

[0058] In actual application, when the power is turned on, the product is in standby mode. If the microswitch detection circuit 7 senses that a cutting board has been put down, the sterilization function is immediately started: the fan, heater, ultraviolet lamp and other functions are started in turn to dry, heat, and disinfect the knives, cutting boards, chopsticks and other items in the storage bucket.

[0059] When the drying and heating process reaches 30 minutes, the program stops drying and heating and starts the ultraviolet disinfection lamp disinfection.

[0060] After the power is turned on, the radar sensing circuit 6 starts working. When the user (or moving object) sensed by the radar enters within 2 meters of the integrated water sink, the atmosphere light automatically lights up. At the same time, the ultraviolet sterilization lamp immediately turns off and stops working after the radar senses that a user is approaching, to prevent the user from being exposed to the ultraviolet sterilization lamp; when the user leaves the integrated water sink within 2 meters for 20 seconds, the atmosphere light turns off and the ultraviolet sterilization lamp turns on to continue the disinfection function.

[0061] In this embodiment, the following functions are also included:

[0062] Self-start function: When the user does not use it for several consecutive days, the above functions will be automatically started for sterilization and disinfection every 3 days (72 hours).

[0063] Stop function: If the user needs to turn off the disinfection function midway, press and hold the "Power Off / Start" button for 3 seconds to turn off all functions.

[0064] Automatic water in and out function: After the user has selected the corresponding items to be cleaned, the user can press the start button to automatically start cleaning. At this time, the main control will drain the water tank according to the initially set water volume, and when the items to be cleaned are automatically cleaned, the water in the tank will be automatically drained.

[0065] Disinfection function: The system automatically turns on the sterilization function according to the cleaning progress and turns it off within the preset time.

[0066] Real-time display function: When the user operates during use and a pre-alarm error occurs, the system will display the corresponding error on the display screen.

[0067] Error alarm function: When the system detects an operation error, it will automatically drive the buzzer to sound an alarm and will not execute the next step.

[0068] Therefore, compared with the prior art, the present invention integrates the sink with multiple functional modules, various functions can be used in a centralized manner, the spatial layout is more reasonable, and it is conducive to the modular installation of the integrated sink, improving the installation efficiency. The multifunctional intelligent integrated sink integrates temperature detection, human body sensing, cutting board detection, drying, disinfection, sterilization, atmosphere lighting and heating functions on the sink, and reasonably combines them, uses human body sensing for related control, makes kitchen and bathroom products more intelligent, enhances the user experience and safety of use, and can effectively solve various needs of people.

[0069] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
