“HAND AND FOOT WASHING DEVICE”

FIELD OF THE INVENTION

The present invention relates to a washing appliance and more particularly to a device for washing hand and foot.

BACKGROUND OF THE INVENTION

Maintaining good hygiene and cleanliness is one of the best ways to stay healthy. Personal hygiene not only benefits one’s personal health but also impacts the people around that person. Maintaining personal as well as public cleanliness prevents spread of various diseases and infections. The importance of good hygiene and cleanliness is now even more apparent due to the pandemic. It is well known that washing hands and feet regularly is a very primitive yet effective and important form of hygiene.

Washing hands and feet before entering homes, workspaces, religious places like temples, swimming pools, etc. was a very common practice and custom especially in Asian households to maintain hygiene and cleanliness. However, due to the recent trend of living in building complexes, apartments and studio apartments that is in smaller houses especially in cities this practice of washing hands and feet regularly before entering is nowadays lost and ignored. Recently due to the pandemic, the extreme importance of maintaining hygiene and cleanliness has become very apparent. Currently, water taps and basins are provided outside larger homes and temples to facilitate washing of hands and feet before entering. However, the drawback of washing hands and feet under the current water taps and basins is that the taps and basins require a lot of space and cannot be installed outside smaller offices and homes. Another drawback of this type of taps and basins is the used water is left to run off in the open that causes wastage of water, soil pollution and in some cases become breeding grounds of mosquitoes.

German Patent DE29701860U1 discloses a portable bathroom module. The invention discloses a bathroom module with wash-basin located in a showering room along with a lavatory. The drawback of this type of invention is that module requires a considerable amount of space and cannot be installed outside an apartment in a building complex. Another drawback of this type of invention is that the module does not provided automatic cleaning of foot especially on the rear side of the feet. There is a need of a device for cleaning hand and feet that is portable and installable outside small apartments. There is further need of a device for cleaning hands and feet that detects and automatically cleans the feet and hands of a user.
