摘要

A hygienic device for human faeces in which at least two toilet cabines can be automatically rotated around their joint central axis. One of the cabins is ready for use, while the other is being cleaned. Applications for rotary toilet devices exist mainly where fairly large and large numbers of people have to share a confined space for periods of varying duration, for example in aircraft, buses, ships and railway trains. Applications may also include their use in leisure centres such as camping sites and bathing facilities, or sports centres, open-air concerts and theatres, conference and congress buildings and civil protection installations.
