Abstract
Description
[0001] MULTIFUNCTIONAL HYGIENIC HAND AND FOOT WASHING UNIT
[0002] Technical Field
[0003] The invention relates to a multifunctional hygienic hand and foot washing unit which enables personal hygiene needs to be met in a practical, ergonomic, and independent manner, allowing users to wash their feet, dry them and put on socks, wash their hands and ensure hygiene, and which provides both ease of use and a hygienic experience through its movable sink mechanism and automatic features.
[0004] Background of the Invention
[0005] In the prior art, various units and apparatus used for foot washing or ablution purposes are known. These products generally suffer from problems such as limited functionality, lack of ergonomics, and an inability to adequately meet hygiene standards. The existing products can be grouped as follows:
[0006] • Fixed foot washing basins: These basins, which are commonly used in places of worship or sports facilities, are generally fixed and do not allow users to sit or perform the operation in a comfortable position. This situation constitutes a significant obstacle for individuals with limited mobility.
[0007] • Portable apparatus: Various portable washing apparatus generally require a faucet connection. However, such devices create installation difficulties and are not user-friendly due to the requirement to manually control the water flow. • Standard sinks: Most sinks have designs that cause accessibility difficulties for users. In particular, these sinks are not suitable for individuals using wheelchairs and cannot be used without additional support.
[0008] • Systems lacking hygienic features: The existing solutions do not include advanced hygiene functions such as automatic soaping, drying, or sterilization. Users require additional equipment or products in order to perform these operations.• Inclusivity issues: The existing designs are generally produced only for specific age groups or for users in good physical condition. Usability for individuals with disabilities or for elderly users is therefore highly limited.
[0009] The currently available units exhibit ergonomic deficiencies. Most existing products require users to remain standing for extended periods and do not provide seating support. Furthermore, height and position adjustments cannot be made for users with disabilities. The existing products also lack modern hygiene functions such as UV sterilization, sensor-operated soaping, or automatic drying.
[0010] Considering the inadequacies of the existing products and the increasing elderly population as well as the need of physically disabled individuals to maintain independent living, the importance of the multifunctional hygienic hand and foot washing unit invention becomes even more evident. Furthermore, during periods in which hygiene is critical, such as pandemics, such integrated solutions provide significant benefits in terms of protecting both individual and public health. Unlike existing products, the invention offers a solution that is both user-friendly and hygienic, thereby improving users’ quality of life.
[0011] When compared to existing products, the multifunctional hygienic hand and foot washing unit invention offers numerous advantages both technically and practically. Primarily, its advanced technology that integrates multiple functionalities enables individuals with limited mobility to meet their hygiene needs independently. In particular, while ergonomically inadequate solutions such as fixed foot washing basins require users to remain standing for extended periods, the invention provides a comfortable experience by including a stool that allows seated use. Moreover, whereas standard sinks and shower apparatus generally create accessibility difficulties, the movable sink and sensor-supported mechanisms included in the invention eliminate these difficulties, providing an inclusive solution suitable for individuals of all ages and physical conditions.
[0012] The invention, which also introduces significant innovations in terms of hygiene, is equipped with advanced technologies such as UV light (ultraviolet light) and sensor-operated foot drying. While existing systems generally include manual soaping anddrying operations, the invention incorporates modem hygiene solutions such as automatic liquid soap spraying and a 360-degree washing pipe. These features enable users to achieve maximum hygiene with minimal effort. Furthermore, a unique additional component included in the invention, such as the sock donning apparatus, provides a specialized solution aimed at improving the daily quality of life of individuals with limited mobility.
[0013] The need for the invention arises from the lack of a holistic system that allows users to meet their personal hygiene requirements independently, comfortably, and effectively. The absence of ergonomic, hygienic, and inclusive designs in existing products constitutes a serious problem, particularly for individuals with disabilities and elderly users. The multifunctional hygienic hand and foot washing unit invention aims to enhance hygiene standards not only for individual users but also for collective-use environments such as hospitals, nursing homes, and places of worship. The innovative solutions offered by the invention go beyond existing alternatives through both their technical superiority and practical ease of use, and therefore play a critical role in improving users’ quality of life.
[0014] The innovations introduced by the multifunctional hygienic hand and foot washing unit invention by eliminating the deficiencies present in existing products can be summarized as follows:
[0015] • Ergonomic design: Components such as the stool seat, stool leg, and movable sink included in the invention enable users to comfortably perform operations both in a seated and standing position.
[0016] • Fully integrated hygiene solutions: The invention elevates users’ hygiene standards to the highest level through features such as UV light-based sterilization, automatic liquid soap spraying, and sensor-operated foot drying.
[0017] • Ease of use: Components such as the push-pull faucet, shower pedal, movable sink, and wheels provide ease of use.
[0018] • Inclusive design: The invention is designed to be suitable for use by individuals of all ages and physical conditions.
[0019] • Multifunctional use: The invention combines multiple operations, such as washing, soaping, drying, and sock donning, within a single system.The structural and characteristic features and all the advantages of the invention will be more clearly understood due to the figures and detailed descriptions provided below and, thus the assessment should be made considering this detailed description.
