  • Patent number: 9670659
    Abstract: A nozzle assembly and a bidet including the same are provided. The nozzle assembly may include a plurality of sitz bath nozzles dispensing jets of water, wherein a plurality of water streams formed by the jets of water dispensed by the plurality of sitz bath nozzles contact each other at a water contact point to form fountain-like water streams. Thus, a clinical effect of the sitz bath is brought about as the pressure inside the anus is reduced. In addition, secondary diseases such as the urinary tract infection and the like for female users may be prevented, and the stress exerted to the anus at the beginning of the sitz bath function may be significantly decreased.
