Sanitary washing apparatus

Abstract

A sanitary washing apparatus includes a washing nozzle (410) configured to discharge wash water toward a human body part, the washing nozzle including: a water supply path (411) configured to pass the wash water; an orifice (413) configured to direct the wash water passed through the water supply path toward the human body part; a throat (417) provided on a trajectory connecting the orifice and the human body part; a mixing chamber (415) provided on a downstream side of the orifice and on an upstream side of the throat, an area of a cross section of the mixing chamber perpendicular to a discharge direction of the wash water being larger than an area of a cross section of the orifice perpendicular to the discharge direction; and an air intake portion (423) configured to take air into the mixing chamber by a negative pressure generated by wash water flowing from the orifice toward the throat, a return flow being generated in the mixing chamber by wash water flowing out from the orifice and having a flow direction changed by a wall face of the mixing chamber, the air sucked into the mixing chamber via the air intake portion being mixed into the return flow as an air bubble, the return flow mixed with the air joining wash water flowing from the orifice toward the throat and being discharged from the throat.

Description

technical field [0001] The aspect of the present invention generally relates to a sanitary cleansing device, and specifically relates to a sanitary cleansing device for washing the "bottom" and the like of a user sitting on a Western-style toilet with water. Background technique [0002] In a sanitary washing machine, in order to improve the feeling of washing, for example, it is generally considered that a washing method that realizes both the stimulating feeling and the sense of volume of the washing water is preferable. In order to further enhance the stimulation, it is necessary, for example, to further increase the flow rate of the spouted water, and to spray the water to the human body without attenuating the further increased flow rate in the flow path. [0003] As a method of increasing the jetting water flow rate, for example, a method of reducing the diameter of the washing flow path and further forcibly increasing the flow rate by using a pump, etc. are mentioned....

AI Technical Summary

Problems solved by technology

For example, if water is supplied at a flow rate exceeding the hot water generating capacity of the instant heating heat exchanger, the supplied water cannot be sufficiently heated in the instant heating heat exchanger.

Therefore, there may be temperature unevenness in the generated warm water or the specified warm water may not be generated.
