Hand washing, disinfection and automatic massage machine, and method of operating the same

A method of operating a hand washing, disinfection and automatic massage machine comprising a Liquid Crystal Display (LCD) touch screen, signal Light-Emitting Diodes (LEDs), a support frame, a wrist lock controller comprising a wrist lock mechanism, a first motor, a rotary bar, and thrust levers, the wrist lock mechanism comprising a fixed plate, a movable plate, and movable blades located between the fixed plate and the movable plate, the hand washing, disinfection and automatic massage machine further comprising a movement controller, a washing and disinfection compartment, Ultraviolet (UV lamps), a wastewater treatment compartment, a water pump and air blower compartment, an energy source, and a controller, said method including the following steps:

• i) selecting setting parameters for the operation mode of said hand washing, disinfection and automatic massage machine;
• if a user wants to change the operation mode pre-programmed for the hand washing, disinfection and automatic massage machine follow step ii);
• otherwise perform step iii);
• ii) setting parameters for the controller to control operation mode of the hand washing, disinfection and automatic massage machine through setting keys on the interface of the LCD touch screen;
• wherein the parameters set by the user shall not be less than the values of the pre-programmed parameters of the hand washing, disinfection and automatic massage machine;
• iii) performing a cycle of hand hygiene and massage by the controller that transmits motion to the rotary bar and the thrust levers, to rotate the movable plates and the movable blades creating full openings on the wrist lock mechanisms for the user to insert their hands into the washing chamber;
• if the user's hands are in the correct position, the wrist lock mechanisms are driven by the first motor causing the movable blades to slowly radiate until they touch the user's hand, and the yellow light of the signal LEDs lights up to indicate that the hand washing, disinfection and automatic massage machine is performing the hand hygiene process;
• wherein the washing and disinfection compartment performs the cycle of hand hygiene and massage;
• if the user's hand is not properly positioned, an error message is displayed on the interface of the LCD touch screen;
• iv) cleaning the machine and getting ready for the next hand hygiene process by controlling the wrist locking mechanisms so that the movable blades radiate completely to close the wrist lock mechanisms;
• next, spinning a fourth motor, a fifth motor and a sixth motor at high speed to cause water to splash from a wiper cluster, a brush cluster and a massage cluster;
• finally, turning the UV lamps on for a preset time to disinfect inside the washing chamber;
• at the end of the hand hygiene process, the UV lamps are off, and the green light of the signal LEDs lights up to indicate the hand washing, disinfection and automatic massage machine is ready for next hand hygiene;
• wherein for the case of a user performing step ii), the controller adjusts the hand washing, disinfection and automatic massage machine to the default programmed operation mode.
