In addition, a and b are the positions for washing the anus and bidet, which are local parts of the human body, respectively, and A and B are nozzles for injecting washing water to the anus a (wet washing) and bidet b (bide washing), respectively. The extended position.
In addition, when the butt cleaning is performed, it is intermediate between A and B (for convenience, C), but is not shown because it is complicated.
[0027]
Moreover, as shown by the arrows in FIG. 6, the local cleaning range can be expanded by reciprocating the nozzles at the extended positions A, B, and C with a small stroke.
[0028]
Furthermore, by changing the position to reach instantaneously, it becomes possible to instantly clean the local area over a wide range. Further, by changing the repeated position, it is possible to experience a different feeling of cleaning instantly and to eliminate the monotonous feeling.
[0029]
In the above configuration, the operation of the part constituting the water circuit of the toilet with the local body cleaning device will be described before the cleaning water is jetted onto the human body.
[0030]
First, in the standby state (the seating SW is in the ON state), the buttocks washing SW, the main flow path solenoid valve, and the body washing solenoid valve are in the OFF state (non-operating state), the nozzle is in the stowed state, and the flow control switching The valve is in a position (= SC) where the inflow path and the two outflow paths are all in communication.
[0031]
Next, when the buttocks SW as a request for injecting wash water into the anus is operated, the main flow path solenoid valve is turned on (water channel open state), and the wash water is discharged from the ejection hole of the nozzle in the housed state. Be injected. The jetted cleaning water is reflected by the cleaning chamber constituent members arranged on the opposite side, and the nozzle is cleaned (= pre-cleaning).
After completion of pre-cleaning (that is, after the main flow path solenoid valve is turned off), the pressure in the hot water tank is released (= pressure release).
After depressurization, the flow control switching valve moves to the water stop position (= flow control movement).
After the flow adjustment, the nozzle extends, but after a short delay (approximately 0.3 seconds), the fuselage washing solenoid valve is turned on (water channel open state), and the nozzle being extended Clean the surface (= extension (body cleaning)).
[0032]
After the extension (body cleaning), the main passage solenoid valve is turned on to perform actual butt washing, and the water channel opening by the flow control switching valve is gradually advanced (= soft start).
After the soft start, perform local cleaning with the water of your choice (= main cleaning).
[0033]
When the stop SW (or the dry SW) as a stop request for the wash water is operated, the main flow path solenoid valve is turned off (water channel closed state), and the injection of the wash water is stopped. The nozzle and the flow control switching valve are maintained as they are, and the pressure accumulated in the hot water tank is released (= pressure release).
[0034]
After depressurization, the flow control switching valve is moved to the water stop position (= flow control movement).
After completion of the flow adjustment, the nozzle is stored in the storage position, and at the same time, the body cleaning electromagnetic valve is turned on to clean the surface of the nozzle (= storage (body cleaning)).
Here, the body cleaning electromagnetic valve 32 is turned off slightly earlier (approximately 0.5 seconds) than the end of the storage of the nozzle.
[0035]
After storage (body cleaning), the flow control switching valve is moved to the SC position, the main flow path solenoid valve is turned on (water channel open state), and cleaning water is injected from the nozzle ejection holes in the storage state. . The sprayed cleaning water is reflected by the cleaning chamber constituent member disposed on the opposite side to clean the nozzle (= post-cleaning).
[0036]
After post-cleaning, the flow control switching valve is moved to the home position (= origin adjustment), and further, the flow control switching valve is moved to the SC position (= flow control movement) to complete the cleaning.
In the flowchart of FIG. 7, when the cleaning of the local cleaning device is completed, a cleaning end signal is output from the electronic control unit to the counting device. When the counting device counts a predetermined number of times (n times), it outputs a signal to the toilet bowl cleaning device.
[0038]
In toilet flushing, when the toilet flushing device receives a signal from the counting device or an operation signal from the toilet flushing SW, the toilet flushing on / off valve is activated to start water supply to the toilet bowl. Next, the vacuum on-off valve is activated to suck in sewage containing filth and drain it to the outside.
[0039]
When the bidet SW is operated instead of the buttocks cleaning SW, the water circuit of the local cleaning device performs substantially the same operation as in the buttocks cleaning.
[0040]
Further, the counter device does not discriminate the number of times of buttocks washing and the number of bidet washings. For example, when the butt washing is used once and the bidet washing is used once, the counter is counted as a total of two times.
[0041]
