Title: Toilet with washing function
Inventor: KAWAGURI MARIKO
IPC: E03D9/08
Filed: 1995-04-12
Abstract: PURPOSE: To allow a proper washing process by providing a drainage recovery vessel for collecting a part of drainage generated at a washing process with a washing liquid, a drainage analyzer for making judgement about a washing extent, and a washing control section for controlling the washing process. CONSTITUTION: According to an instruction from a washing control section 21, warm water is jetted from a washing nozzle 1, thereby starting a washing process. Drainage after the washing process, while entering a drainage collector via the inlet 5 thereof and flowing out from the outlet 6 via a channel 2, is analyzed with an LED 3, a photo diode 4 and a judgement section 20. At the start of the washing process, a contaminant is contained in wash water and light emitted from the LED 3 is much reflected. Also, a light quantity received with the diode 4 is large. In the course of the progress of the process, the turbidity of a cleaning liquid is reduced and the reflected light quantity is also reduced. At the same time, the received light quantity becomes small.  Then, the section 20 judges the end of the process, when the received light quantity reaches the preset value, and outputs the result of the judgement to the section 21. This section 21, upon receipt of a signal from the section 20, controls the washing process with the cleaning liquid.
