This study is about the bidet which is used to clean the anal and local parts after the user seated on the left side of the toilet in the toilet. The cleaner of the bidet which is contaminated from various bacteria and dirt is washed clean with clean water to keep it clean The present invention relates to a cleaning device for a bidet cleaner that hygienically maintains a bidet used by a plurality of users. As a result of developing and studying a bidet nozzle that can be implemented with a bidet nozzle and a washing nozzle for automatically washing the jetting head of the bidet and the jetting head, the optimum jetting time of the nozzle after the hydraulic jetting is 1 second To 10 seconds, it was confirmed that the nozzle cleanliness of an average of 5 seconds was maintained at 100%. Subsequent studies will require further study of the durability of the product and the cleaning safety at a pressure of $5kg/mm^2$. Toilet bidet is a product that is closely related to the safety and life of the people, but the development of various technologies is still insufficient. Therefore, it is meaningful that this study contributed to the quality of life of the people by continuously researching and developing the bidet.

This study uses the bidet 4D double diamond design process model to propose an improvement for "senior-oriented bidet product service design" that reflects the characteristics and needs of seniors. This study was based on the product service system concept. To this end, qualitative research on seniors was conducted to derive user value factors, and, based on this, product service ideas were discovered, and a prototype reflecting the usefulness review of a working-level expert group was proposed. First, a "smart application service for user-customized function setting guide" was proposed. A bidet incorporating Internet of Things technology and a smart phone are linked to provide an app service that automatically interprets user characteristic information and information on bidet products to guide customized functions. Second, a control panel and remote control user interface to "user-oriented product service interface" was proposed. In consideration of the usability and cognitive ability of seniors, a simple and intuitive physical user interface such as a configuration centered on main functions, button arrangement according to task sequence, and a touch screen remote control was presented. Third, we proposed a "bidet care service linked with products and health/hygiene care" that provides a wide range of services such as user health and hygiene, cleanliness, entertainment, etc., in addition to regular bidet product service. This study proposed a product-based service design methodology that can improve user experience and relationship quality by discovering and improving the pain points and needs of users (seniors) in the process of using bidet products (before, during, and after use).

There are an electronic and a manual type in Bidet. The electronic bidet has some advantages. it supplies multiple functions and is up easily. However, it has frequent defects and a high price. The manual bidet is not need to supply electric and is cheaper than the electronic type. However, it is needed to supply hot water and is hard to set up. In order to solve these defects, this study designed a bidet heating unit using an electric instantaneous water heating method. To get a proper heating elements, experiments were performed about a Ni-Cr heater and a film heater.

An optimized bidet nozzle design to form the required swirl water jet is proposed with the help of numerical analysis. The bidet can do the cleaning process of human body by water injection and the speed/pressure/injection angle/magnitude of swirl intensity of water jet determine the cleaning capability and personal subjective feeling. The objective of this research is to design optimal water injection nozzle to make stable swirl intensity. The effect of individual design variables are analyzed from the basic design and the final design is deduced to make high performance water jet within the pre-determined operation conditions.

Bidet is widely used and is being developed for multipurpose. However, use of this bidet varies by the elderly and disabled people. Therefore, this research compares and analyze need of bidet for elderly and disabled people and by many different types. This survey was conducted targeting 39 elderly and 120 disabled people. This survey is consist of questions that varies by bidet companies and includes questions like UI cognitive abilities, automatic water flushing, position of control box and necessary of embossment for icons. As a result, elderly and disabled people showed similar in result but for visually impaired person, the ratio of preference showed 1:9 which is opposite. As for visually impaired person, the ratio of preference showed 1:9 which is pretty high.

In this paper, the module which can measure body fat, heart rate and $SpO_2$ has been developed for being mounted on widespread bidets in the home. This moudule was manufactured by a structure that can be mounted on a bidet, users such as elderly, patients with chronic fatigue, heart disease and overworked workers checking their health status in every life through monitoring their body fat, heart rate and $SpO_2$ and preventing of sudden death.

We have studied that a effect saving temperature of instantaneous heater using an economical bidet due to change Silicon-Tube. The results, we have found that the existing instantaneous heater is reduced 15 [%], 20 [%] better than a new product instantaneous heater as a discharge water [${\ell}$/min] with temperature and ${\nabla}$ value, respectively. Therefore, we have showed that the innovative effect of a working process and the cost reduction because an economical bidet due to change Silicon-Tube.
