Device, the distributor are provided with the device for detecting paper consumption.Then the detection means is also electrically connected to monitoring unit 12.Paper
Detect the combination of usage time and/or frequency of use, paper consumption or both that can be based on distributor.
Monitoring system 2 can also include device 10, for detecting the solid constituent of excreta, i.e., substantially solid excretion
Thing.Such detection means 10 can be optical type, that is, be configured and positioned within basin bottom part residual water top with
Just falling for solid state component is detected.In fact, such element has minimum surface area and thickness in practice.In addition, it
Systematically fall vertically.Their testing result by the optical barrier for being arranged in basin bottom residual water surface is special
Favourable.
Monitoring unit 12 is configured as the function of the consumption of toilet paper and the seat also as user on toilet seat 4
The function for position carrys out order flusher valve 43Actuator 16.More precisely, water-flushing device leaves the position that is seated in user
When putting, automatic triggering, as long as he has already consumed by toilet paper when being sitting in seated position.In fact, if he is sitting on toilet seat
Then a number of paper is had already consumed by when standing up, it means that he is likely to complete consumption toilet paper.Therefore,
Once user stands up, it is suitable for triggering the purpose that water-flushing device finally rinses to reach.On the contrary, if user is sitting in toilet seat
Also without consumption toilet paper when on device, it means that when he leaves seated position to stand up, he is likely to contemplate straight
Wipe immediately and thus consume toilet paper.In this case, water-flushing device will not directly trigger after user stands up, and see
Time delay is observed, and in the case where detecting paper consumption, as long as toilet paper is consumed, time delay will extend.
Fig. 2 is to show the flow chart for being used to monitor the general principle of the method for water-flushing device according to the present invention.First step
20 be the seated position for detecting user on toilet seat.If detecting user in the position, detection in step 22 is defended
The consumption of raw paper, while user is still within seated position.If detecting the consumption of toilet paper in user's seated position,
The fact that user leaves the position is then detected in step 24.In this case, user is considered as when being seated
Through completing wiping operation, it is triggered once water-flushing device described in he leaves seated position, in step 26, the triggering of water-flushing device
Then correspond to finally rinse.This is avoided user must not hence in so that water-flushing device can automatically be triggered in the correct time
Do not turn round manually to start water-flushing device.
Referring still to Fig. 2, in step 22, when user is in seated position, disappearing for toilet paper is not being detected
In the case of consumption, when user leaves seated position by standing, in a step 28, health is then detected in step 30
The consumption of paper, this exceedes predetermined initial elapsed time, such as several seconds.At the time of seated position is had been moved off from user
The given elapsed time in without consumption paper in the case of, do not take with triggering the relevant action of water-flushing device, and in step 32
Stop monitor.Such case has been sat down on toilet seat without consuming toilet paper and being likely to corresponding to user
Do not drain anything.It should be noted that still can be with water-flushing device described in manual command.Still in step 30, if from
The consumption that seated position detects toilet paper afterwards and within the predetermined elapsed time after possible time delay 34 is opened, then
Water-flushing device is triggered in step 26, is rinsed corresponding to final.Time delay 34 is designed to avoid not yet completing to wipe in user
Water-flushing device is triggered while wiping operation.In fact, this operation generally corresponds to a series of toilet paper consumption, it is consumed every time
The wiping action that several seconds may be continued afterwards.It is therefore advantageous that after consumption toilet paper every time is provided in step 30
Time delay, the time delay can be several seconds, such as in the range of 5 to 15 seconds.
Referring still to Fig. 2, in step 22, toilet paper is considered as to be only just consumed after minimal consumption amount be probably to have
Profit.Actually, it may occur that user may attempt to operate the distributor of toilet paper without actual consumption toilet paper, otherwise may be used
It can happens is that, such as a small amount of toilet paper is consumed to wipe nose, and not start actually and wipe action.The minimum disappears
The paper and/or the use duration of distributor that consumption can be based on certain length.These commentaries given above are also applied for
The consumption of paper is detected in step 30.In fact, in order to reasonably consider that wiping operation has been completed, paper should be reached
Minimal consumption amount.It can correspond to the total length of paper, such as 50 centimetres.It may correspond to operate the distributor of paper
Total time, such as 20 seconds." total length " and " total time " is understood to cumulative length and cumulative time, it is contemplated that wiping operation leads to
A series of paper consumption often interrupted by appropriate wiping action forms.

Once the seated position that user is on toilet seat, the detection correspond to step 120, detected in step 138
The appearance of solid constituent.If detecting solid constituent, according to step 142, alternatively according to time delay 140, and also have
Sharp ground, according to the limitation of the number of flushing, such as the flushing three times according to step 144, then middle rinse occurs.It is once real
Now predetermined middle washing time, according to step 146, stop for monitoring the middle method rinsed or rinsed.
These measures allow to effectively neutralize offending smell, so do automatically and limitedly consume water.It is true
On, the volume for water that is middle and finally rinsing advantageously rinses required volume significantly less than traditional single.The volume can
With for example in the range of 1 to 3 liter, preferably in 2 liters of magnitude.Or the centre is rinsed or each middle rinse can be right
Ying Yu ratios finally rinse the volume of small volume.
Parallel with the appearance of detection solid constituent, this method is provided in a manner of the method similar to Fig. 2 in step 122
