Further, prior to the protrusion of the cleaning wastewater recovery cell 46, clean water is supplied for removing stains after a long period of non-use and for checking the function of the cleaning wastewater analysis function unit 27 at the start of use.

FIG. 6 shows a control block diagram of this embodiment.
In the controller 53, a delay timer 67 is provided so that cleaning can be started after the cleaning operation, a timer 68 as a supplemental means when the recovery of the cleaning wastewater or an analysis of the cleaning wastewater cannot be reliably performed, and a cleaning water. An automatic cleaning control unit 69 that controls the pattern, water force, and nozzle operation is provided.

Further, the cleaning wastewater analysis function section 27 is provided with a reference check section 70 and a light quantity adjusting section 71. In addition, a motor 72 for driving the nozzle, a pump 73 for adjusting the pressure level of the water passage and the water pressure from the nozzle, and the like are provided.

Next, the operation of this embodiment will be described. The control operation is shown in the flowchart in FIG. When the user presses the bottom switch 33 of the remote controller 32, first, the solenoid valve 52 is opened, and the cleaning wastewater recovery cell 46 is opened.
Fresh water from the water supply 22 is supplied at a high speed for a predetermined time to remove dirt when not in use. Then, using the collected fresh water after the dirt is removed, the cleaning wastewater analysis function unit 27
The cloudiness of the transparent walls 56 and 57 and the light emitting diode 5
8 and the deterioration of the phototransistor 59 are corrected. This is because the reference check unit 70 determines that fresh water is stored in the cleaning wastewater recovery cell 46, and the light amount is adjusted so that the output of the phototransistor 59 that receives the light emitted from the light emitting diode 58 falls within a predetermined range. This is performed by adjusting the amount of electricity supplied to the light emitting diode 58 in the section 71.

Next, the posterior nozzle 43 and the cleaning waste water recovery cell 46 are projected. This operation is performed by the control valve 45 and the control valve 4.
8 is opened, and the posterior cylinder 44 and the sewage recovery cylinder 45 are exposed to water pressure to cause the protrusion.

Further, at this time, the timer 68 built in the controller 53 operates, and functions as a supplemental means in the unlikely event of a failure or when waste water cannot be collected.

The bottom nozzle 43 and the cleaning wastewater recovery cell 46
When is sufficiently projected, warm water as washing water is supplied to the human body, and the automatic washing control unit 69 starts prewashing of the anus. During this pre-washing, the air pump 45 'operates to mix air bubbles into the wash water, so that the jet flow from the posterior nozzle 43 interferes and swings, and the wash water is supplied to the human body in a wide range. As a result, the stool mass that has adhered to the anus and the like is evenly removed, and the function of pre-washing is fulfilled.

The hot water supplied from the posterior nozzle 43 is
After hitting the area around the anus, part of it is scattered as sewage, and part of it is transmitted to the user's hips and drops downward at the convex part of the buttocks, and is collected by the washing sewage recovery cell 46 provided at the bottom. The dropped water accumulates in the concave portion 54 of the cleaning wastewater recovery cell 46, and is sequentially replaced with the falling wastewater.

The turbidity of the wastewater received in the recess 54 is shown in FIG.
As shown in (4), when the predetermined value or more is reached, it is considered that the dirty water has been received, and the completion display lamp 42 provided on the remote controller 32 lights up in red. After that, when the concentration of dirty water in the recess 54 is changing, the completion display lamp 42 is made to blink. When the turbidity level of the recovered dirty water becomes equal to or less than the predetermined value 1, the cleaning mode is automatically switched to the main cleaning. In this main cleaning, stopping and operating the air pump 45 'is repeated, and the bottom cleaning nozzle 43 is moved to the motor 7
Move back and forth in 2. As a result, dirt can be spread over a wide area,
In addition, the peeling action due to the change of the pattern effectively removes it.

When the turbidity level of the recovered wastewater becomes a predetermined value 2 or less and the level of the predetermined value 2 or less continues for a predetermined time, it is judged that the cleaning is completed, and the completion display lamp 4
Change 2 from blinking red to lit green. Then, the air pump 45 ′ is stopped, the control valve 45 and the control valve 48 are closed, and the posterior washing nozzle 43 and the washing dirty water collecting cell 4 are operated by the operation of the posterior cylinder 44 and the dirty water collecting cylinder 47.
6 is stored.

As described above, the color tone of the filth on the user's body is not determined to determine the filth removal status, but the collected wash filth water is analyzed, so that it can be detected by the color and lightness of the skin. It is possible to accurately determine the removal status of collected sewage, even if there is an error, the stool attached to the folds of the anus, or the fall of stools covered by the pubic hair on the anus of a boy.

Further, since the cleaning is automatically stopped when the area around the anus is cleaned, the conventional cleaning is continued without knowing when the cleaning is completed, wasteful hot water is used, and water is saved and energy is saved. You can solve what was going against. In addition, even for the user, it is possible to stop the cleaning in a state where the dirt is not sufficiently removed, notice it by wiping with a paper, and not to perform the cleaning again, and the cleaning can be finished quickly and accurately by omitting the operation. Convenience increases.

Further, since the display can be performed by the remote control together with the automatic stop, the user can visually recognize the completion of washing, and even a person who has lost the sensation of paralyzing the lower half of the body can immediately move to the next action.

In the event of incorrect use, failure, or inability to collect sewage in the middle of the process, the sewage does not continue to be received in a controllable manner, or the turbidity level does not change. When the time set according to the cleaning pattern and water pressure has passed, the cleaning is automatically stopped.
At this time, although not shown in FIG. 7, the fact is displayed on the remote controller 32.

When the cleaning / sewage recovery cell 46 is stored in the warm water cleaning toilet seat body 21, the electromagnetic valve 52 is opened again for a predetermined time, and the cleaning / sewage recovery cell 46 is cleaned with fresh water. For this reason, the dirt adhered to the cell portion, the upper surface edge, and the side surface of the cleaning dirty water recovery cell 46 is dropped before it has dried, and dirt is accumulated even after long-term use, and the transparent walls 56 and 57 are fogged. It is possible to prevent it from getting worn out, and it becomes excellent in reliability.

FIG. 9 shows a second embodiment of the present invention. In this case, the mechanical structure is the same as that of the first embodiment.
Although the configurations shown in (a) and (b) are adopted, the control operation is different, and the difference will be mainly described.

When the posterior switch 33 is pressed, the cleaning dirty water collecting cell 46 is cleaned and then the control valve 45 is opened so that only the posterior nozzle 43 is projected.

At this time, the timer built in the controller 53 is activated, as a transition means for ending the pre-wash and shifting to the main wash, as a projection timing means for the projection of the cleaning wastewater recovery cell 46, and in the event of a failure. It also serves as a supplementary measure when wastewater cannot be recovered.

When the posterior nozzle 43 is sufficiently projected, warm water, which is washing water, is sprayed on the human body, and prewashing is started.
Then, when the predetermined time set by the timer has elapsed, the main wash mode is entered. After a lapse of a predetermined time in the main washing mode, the control valve 48 is opened by the function of the timer and the washing dirty water collecting cell 46 is projected.

The reason why the cleaning sewage recovery cell 46 is made to protrude at the time when this main washing is progressing is that when the cleaning sewage recovery cell 46 is made to protrude from the beginning as in the first embodiment, the cleaning sewage recovery cell 46 is made from the time when the sewage is still considerably dirty. Since sewage enters the tank, it has the advantage of being able to predict the completion time, but on the other hand, it has the drawback of becoming easily soiled and requiring time to clean, but this is to reduce this.

The following operation is the same as that of the first embodiment and will not be described. 10A and 10B show a third embodiment of the present invention.

In the third embodiment, the posterior wash nozzle 43 and the wash waste water recovery cell 46 are projected by hydraulic extrusion in the first and second embodiments, but in the third embodiment, the motor is used. It is driven to project.

The posterior washing nozzle 74 and the washing dirty water collecting cell 75 are configured so that they can be freely projected and stored via a belt 77 by a motor 76. Then, the posterior washing nozzle 74 and the washing dirty water collecting cell 75 are engaged with each other by the connecting portion 78, and both are projected and housed by one motor 76. Also in this embodiment, the cleaning waste water recovery cell 75 has a configuration in which it does not planarly overlap the buttocks cleaning nozzle 74, and the falling water from the buttocks cleaning nozzle 74 during buttocks cleaning falls into the cleaning waste water recovery cell 75. However, the detection value is prevented from causing an error.

The advantage of this motor drive system is that it can be driven at a constant speed and with a constant thrust even when the water pressure is small compared to the water pressure extrusion system, and a separate motor is provided as in the first embodiment. Even without it, it is possible to perform a move operation that repeats moving back and forth and an operation that aligns the cleaning nozzle position with the anus position.

Sewage recovery cell 7 in this third embodiment
Unlike the first and second embodiments, No. 5 is a type in which the recovered sewage overflows, but it also drops downward from a small hole 80 formed in the lower surface of the recess 79 of the wash sewage recovery cell 75. Is taking. For this reason, there is an advantage in that the change in turbidity can be grasped faster than in the forms of the first and second embodiments in which the whole is flooded.

In the above embodiment, the washing means was a hot water washing toilet seat, but in addition to this, a washing device in which the user manually brings the nozzle to the washing portion without fixing it to the toilet bowl, and the washing water is warm water. Various methods are conceivable, such as a type of cleaning device that cleans with water without using.

Further, as the cleaning wastewater recovery means, the cleaning wastewater recovery cell has been taken as an example in the above-mentioned embodiment, but it has no concave portion and is attached to the tip of the recovery rod by the surface tension of the wastewater, or the proximity. Various methods are conceivable, such as holding the dirty water between the two poles with surface tension and sucking the waste water from the tip of the nozzle with a pump.

Further, as the cleaning sewage analysis means, the method of detecting the turbidity of the sewage was taken as an example in the above-mentioned embodiment, but the method of using the conductivity of the sewage or pH (PH), the ion concentration and the dissolved oxygen were used. Method of using, method of using salinity and sugar content,
There are various methods such as a method using specific gravity.

Also in the case of turbidity detection, there are a method of utilizing visible light, a method of utilizing ultrasonic waves, etc. other than the method of utilizing infrared light. Furthermore, as the detection target of sewage, the turbidity of collected sewage due to feces is detected, but there are various methods such as detecting occult blood in feces, detecting fiber content, and detecting pigment.

In addition to the method of using the solenoid valve 52 and the cleaning section 51 as the fresh water supply means, various methods such as a method of controlling the fresh water supply by starting and stopping the pump, a method of setting a brush and the fresh water supply as a set, etc. There is.

Further, although the fresh water used in the above embodiment is water supplied from the tap water, it may be warm water heated by the heating means or treated water such as acidic water or alkaline water.

Further, in the above-described embodiment, the display is performed by the remote controller when the cleaning is completed. However, other notification means include visual display methods such as screen display, auditory methods such as the use of sound and voice, and vibration. There are various methods such as the method of appealing to the sense of touch.

Further, in the above embodiment, the buttocks were mentioned as the objects to be washed, but it is naturally conceivable that a female part or a combination thereof is used. It is also possible to detect components in urine and menstrual blood components with cleaning wastewater.
