Abstract
Abstract A washing device for parts of body comprises a pump means to supply water from a water source under pressure and a nozzle means which spouts the pressurized water against the private parts of human body as a water jet. Since the pump means has an air intake port on the suction side, air foam is securely mixed in the water jet. Also, since an air control valve is provided in connection with the air intake port, the mixing ratio of the air in the water can be controlled by the air control valve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A washing device for parts of a body for use in combination with a toilet comprising: water source means; water heating means for heating water supplied from said water source means; pump means having a suction side connected to said water heating means for sucking up the water heated by said water heating means and supplying the water under pressure; said pump means having an air intake port provided in said suction side for introducing air into the water to form an air-water foam; said air intake port of said pump means is connected to an air control valve having means for regulating the amount of air introduced into said pump means; and nozzle means connected to said pump means for ejecting the pressurized air-water foam toward parts of a body as a controlled jet.
