This application claims priority as a Divisional of U.S. patent application Ser. No. 18/648,126, filed Apr. 26, 2024 and incorporates the same by reference herein in its entirety.

The present disclosure is related in general to personal hygiene and cleaning technology. More specifically, the disclosure relates to a cleaning apparatus designed for cleaning hands through the controlled and customizable dispensing of water, soap, and lotion. Additionally, this disclosure details an apparatus and method that will self-clean the sink. The disclosure also includes additional functionalities like communication with electronic devices, dispensing of soap and lotion based on user preferences, drying elements, UV sterilization and even detection of unusual patterns on the user's hands.

Hand hygiene stands as a crucial element in preserving personal health and preventing the transmission of infections. Traditional handwashing methods, involving manual application of water and soap, exhibit limitations in customization, efficiency, and user experience. Technological advancements have paved the way for innovative solutions to elevate the hand-cleaning process. Conventional handwashing systems often lack customization options, fail to identify users, and may result in inconsistent cleaning patterns. The manual nature of traditional handwashing further contributes to inefficiencies, with a lack of effective feedback mechanisms for users. Additionally, these methods don't offer insights into health aspects. The 2000 worldwide Covid epidemic clearly demonstrated the need for efficient and effective handwashing solutions to prevent the spread of this and other diseases.

Typically, users manually rub their hands together under running water with soap in a process that lacks customization options. The intensity and duration of washing are not tailored to individual preferences, resulting in a non-uniform experience for all users. Moreover, there is no mechanism for user identification, and the lack of feedback mechanisms can cause uncertainty about the thoroughness of the hand-cleaning process. Traditional methods also miss incorporating advanced features like soap/lotion dispensing, UV sterilization, and self-cleaning capabilities. While touchless systems with automated sensors exist, they often lack customization options for users and fail to provide inherent user identification or personalization. Limited feedback mechanisms, relying on visual cues like water flow, further contribute to their drawbacks. Additionally, separate UV sterilization devices require independent use, lacking integration with a comprehensive hand-cleaning system and leading to additional steps for users. Even in facilities with automated hand dryers, the focus is primarily on drying hands, lacking additional features such as lotion dispensing or UV sterilization, and offering no customization options for users in terms of drying duration or preferred temperature. Thus, there is a need for a better more effective solution for hand washing and hand sterilization.

Conventional handwashing methods suffer from a lack of personalization, employing a one-size-fits-all approach to cleaning. These systems do not incorporate mechanisms for user identification, leading to inconsistent cleaning patterns and varying levels of effectiveness. Additionally, the absence of effective feedback mechanisms leaves users unaware of the correct completion of the cleaning process. Health monitoring capabilities are also absent in traditional handwashing systems, and their energy efficiency and self-cleaning capabilities are often inadequate.
