The toilet-flushing apparatus 10 that Fig. 1 represents possesses Western-style toilet (for convenience of explanation following, as only to be called " closet ") 800 and hygienic washing device 100 disposed thereon.Closet 800 has basin 801.Hygienic washing device 100 has shell 400, toilet seat 200 and toilet cover 300.Toilet seat 200 and toilet cover 300 open and close respectively and are bearing on the shell 400 by axle freely.In addition, toilet cover 300 is not to be provided with.

For example in the bottom of shell 400, be provided with water, sterilization water spray nozzle (spraying portion) 480 to basin 801 surface spray of closet 800.Spray nozzle 480 both can be arranged on the inside of shell 400, also can attachedly be arranged on the outside of shell 400.

In addition, when in present specification, mentioning " water ", not only refer to cold water, also comprise heated hot water.And " the sterilization water " in the present specification is meant that the sterilization component of for example hypochlorous acid of being comprised etc. is more than the tap water liquid of (also only being called " water ").

As shown in Figure 2, the toilet-flushing apparatus 10 that present embodiment relates to has the 1st stream 21, the water guiding spray nozzle 480 that it supplies with waterings such as running water pipe, water storage tank.Upstream side at the 1st stream 21 is provided with electromagnetic valve 431.Electromagnetic valve 431 is electromagnetic valves to be opened/closed, and its instruction control according to the control part 405 that is arranged on shell 400 inside is supplied water.In addition, the 1st stream 21 is the secondary sides in electromagnetic valve 431 downstreams.

In the downstream of electromagnetic valve 431, be provided with the sterilization water generating unit 450 that can generate sterilization water.The back will be elaborated to sterilization water generating unit 450.Downstream in sterilization water generating unit 450 is provided with Flow-rate adjustment flow channel switching valve 471, itself or carry out the adjusting of the flow of water (flow), perhaps carry out switching or switching that spray nozzle 480 or not shown clean nozzle etc. are supplied water.The 1st stream 21 is in Flow-rate adjustment flow channel switching valve 471 place branches.After flowing through Flow-rate adjustment flow channel switching valve 471, be directed to spray nozzle 480 by the sterilization water of the 1st stream 21 guiding or last water.On the other hand, be directed at Flow-rate adjustment flow channel switching valve 471 place branches the 2nd stream 23 sterilization water or go up that water for example is directed to not shown clean nozzle or nozzle is cleaned chamber etc.Flow-rate adjustment flow channel switching valve 471 can be according to the instruction from control part 405, to sterilization water or go up the lead state of the 1st stream 21 and with sterilization water or go up the lead state of the 2nd stream 23 of water and switch of water.

For example shell 400 is provided with the inductive pick-up 402 of entering the room that detects the user and enter the washroom, human body sensor 403, the detection user that detection is positioned at the user in toilet seat 200 the place aheads has been sitting in the seat formula inductive pick-up 404 on the toilet seat 200.

The inductive pick-up 402 of entering the room can detect the user of door after just having entered the room who opens the washroom, can also detect to be ready entering the washroom and to be positioned in front of the door user.That is to say that the inductive pick-up 402 of entering the room can not only detect the user who has entered the washroom, can also detect the user who enters before washroom user before promptly is positioned at the washroom outer door.Inductive pick-up 402 of entering the room as such can use the microwave remote sensor of thermoelectric pickup, doppler sensor etc. etc.Use utilize microwave Doppler effect sensor or when using launched microwave and detecting the sensor etc. of detected body according to the microwave amplitude (intensity) of reflection, can detect user's existence across the door of washroom.That is to say, can detect and enter washroom user before.

Human body sensor 403 can detect the user who is positioned at closet 800 the place aheads and promptly be positioned at from toilet seat 200 forwards and leave the user of the position of toilet seat 200.That is to say that human body sensor 403 can detect the user who enters behind the washroom near toilet seat 200.As such human body sensor 403, for example can use infrared reflection formula distance measuring sensor etc.

Seat formula inductive pick-up 404 can detect and be positioned at the human body above the toilet seat 200 at once or be sitting in user on the toilet seat 200 before the user will sit on the toilet seat 200.That is, seat formula inductive pick-up 404 can not only detect the user who is sitting on the toilet seat 200, can also detect the user who is positioned at toilet seat 200 tops.Seat formula inductive pick-up 404 as such for example can use infrared reflection formula distance measuring sensor etc.

In the toilet-flushing apparatus 10 that present embodiment relates to, when the inductive pick-up 402 of for example entering the room detected the user who enters the washroom, control part 405 can be implemented water droplet from the control of spray nozzle 480 to basin 801 surface spray of closet 800.That is to say that control part 405 can be embodied in the user and uses the closet 800 preceding basin 801 surface wetting controls of water droplet with closet 800.Thus, can reduce attached to basin 801 lip-deep dirts.

The spray amount of the water droplet that control part 405 control spray nozzles 480 are sprayed, and will be controlled at about 10～50% in the regulation zone on basin 801 surfaces attached to the occupation rate of basin 801 lip-deep water droplets.At this, " occupation rate of water droplet " or " water droplet occupation rate " value that formula described later is derived of passing through in the present specification for relating to according to Fig. 5～Fig. 8." the regulation zones on basin 801 surfaces " are, typically as shown in Figure 1, the center line 805c of the specific volume water surface 805 is by basin 801 surfaces of rear side when for example observing from closet 800 sides.At this, in the present specification, the center line 805c of relative ponding face 805 is vertical horizontal direction when observing from closet 800 sides, will be decided to be " the place ahead " by the place ahead that the user who is sitting on the toilet seat 200 observes, and will be decided to be " rear " by the rear that the user who is sitting on the toilet seat 200 observes.

Generally, the dirt that the user drains, when the side of closet 800 is observed, easily attached to compare with basin 801 surfaces of the center line 805c front side of ponding face 805, by on basin 801 surfaces of rear side.Therefore, will be when observing be controlled at about 10～50% by control part 405, can reduce more expeditiously attached to basin 801 lip-deep dirts attached to the occupation rate of the basin 801 lip-deep water droplets of the center line 805c rear side of ponding face 805 from closet 800 sides.

Occupation rate attached to basin 801 lip-deep water droplets is lower than at 10% o'clock, and attached to basin 801 lip-deep water droplets interval broad each other, it is higher that the part of then not adhering to water droplet on basin 801 surfaces does not promptly have wetted part to adhere to the risk of dirt.In addition, as the method on wetting basin 801 surfaces, commonly used is that the part that will clean water with clean closet equally spues before using closet 800.At this moment, utilization will be cleaned and remain in lip-deep residual water after water is covered with pelvic surface of sacrum integral body.At this moment, though the occupation rate of water droplet about 15%, and is compared the situation of water droplet spraying, the water droplet attachment state on 801 in the basin is inhomogeneous, and the wide model in zone that does not adhere to water droplet distributes.Therefore, can not play consistently and suppress the effect that dirt adheres to, dirt remains in basin 801 lip-deep risks and increases.And, because the major part that spues is cleaned water all under basin 801 surface currents, so, exist 801 in basin to go up can to help the ratio that suppresses the residual water that dirt adheres to less, the viewpoint from economizing on water does not have effect yet.

On the other hand, even be higher than 50%, can not as the high occupation rate of water droplet, reduce attached to basin 801 lip-deep dirts attached to the basin 801 surperficial occupation rates that go up water droplet.And, the spray amount that also can waste water droplet, or need longer spray time.Therefore, when control part 405 is sprayed water droplet before the user uses closet 800, even also spray the danger of water droplet after can existing the user to be sitting on the toilet seat 200.Therefore, exist and to allow the danger of user's uneasiness.

To this, the control part 405 of present embodiment will be controlled at about 10～50% in the regulation zone on basin 801 surfaces attached to the occupation rate of basin 801 lip-deep water droplets.Thus, can make attached to basin 801 lip-deep water droplets evenly to distribute, be reduced in the risk that the part of not adhering to water droplet on basin 801 surfaces is adhered to dirt.Therefore, can reduce attached to basin 801 lip-deep dirts.In addition, can also suppress the spray amount of water droplet, shorten the spray time of water droplet.

When dirt drops on attached to basin 801 lip-deep water droplets top, the dirt water droplet of can crushing.At this moment, be about 2% when above in occupation rate attached to basin 801 lip-deep water droplets, crushed water droplet can spread on basin 801 surfaces, combines with adjacent other water droplets and forms moisture film.Thus, can suppress dirt attached on basin 801 surfaces.The back is elaborated to related content.

The surperficial possess hydrophilic property of the basin 801 of the closet 800 of present embodiment.Thus, from spray nozzle 480 water droplet of spraying positively attached on basin 801 surfaces.Thus, even also can carry out good control, can more effectively reduce attached to basin 801 lip-deep dirts in the high zone of water droplet occupation rate.So-called hydrophily promptly refers to the degree that does not flow down attached to the water droplet on the basin.For example, the surface of the closet that forms with enamel has shown good hydrophilicity.

In addition, the control part 405 sterilization water that can implement sterilization water generating unit 450 is generated is from the control of spray nozzle 480 to basin 801 surface spray of closet 800.With basin 801 surface spray of sterilization water, the basin 801 lip-deep bacterium that are present in closet 800 can be carried out sterilization by spray nozzle 480 to closet 800.Thus, spray nozzle 480 can suppress basin 801 surfaces and go up " dirt " that produces, and promptly suppresses so-called " ring stain ".And, when the sterilization glassware for drinking water has discoloration, for example when having hypochloric acid water, can make the surface of basin 801 become whiter (bleaching).

Control part 405 also can be in the spray amount from spray nozzle 480 time control sterilization water with the sterilization water spray, and will be controlled at about 10～50% in the regulation zone on basin 801 surfaces attached to the occupation rate of basin 801 lip-deep sterilization water.Control part 405 can be by the control spray nozzle 480 sterilization water of being sprayed particle diameter and spray time more easily control occupation rate attached to basin 801 lip-deep sterilization water.Thus, flow to ponding face 805 when inhibition sterilization water sticks in basin 801 surperficial going up or in cohesion thereafter and from basin 801 surfaces, can more expeditiously sterilization water be stayed on basin 801 surfaces.Therefore, can carry out the sterilization on basin 801 surfaces more expeditiously.In addition, when utilizing sterilization water, in order to improve the chance that contacts with bacterium, preferred high occupation rate.

And, in the toilet-flushing apparatus 10 that present embodiment relates to, the inductive pick-up 402 of for example entering the room detect less than behind the user in the washroom through during official hour, control part 405 can be implemented controls that sterilization water is sprayed to basin 801 surfaces of closet 800 from spray nozzle 480.That is to say that control part 405 can be carried out the control of basin 801 surfaces with the sterilization water-wet after the user washes dirt and finishes the use of closet 800.At this moment, with use closet 800 the user before compare when spraying, the sterilization water that spray nozzle 480 is sprayed can rest on basin 801 surfaces for a long time.Therefore, can more effectively carry out the sterilization on basin 801 surfaces.

Fig. 3 is the plane model figure of measuring position of the particle diameter of the illustration spray nozzle water droplet of being sprayed.

In addition, Fig. 4 is the chart of a routine measurement result of the particle diameter of the illustration spray nozzle water droplet of being sprayed.

As shown in Figure 3, the present inventor in the position measurement of the top of only leaving spray nozzle 480 about 25 millimeters (mm) spray nozzle 480 drop particle diameter of being sprayed.At this moment, use the Fraunhofer analytic method to measure the drop particle diameter that spray nozzle 480 is sprayed.The distribution of the drop particle diameter that spray nozzle 480 is sprayed one for example shown in Figure 4.

As shown in Figure 4, the drop particle diameter that spray nozzle 480 is sprayed for example is about 10～1000 microns (μ m).And the average grain diameter of the water droplet that spray nozzle 480 is sprayed for example is about about 50～500 μ m.From adjusting the aspect of water droplet occupation rate effectively, preferred 100～300 μ m of the average grain diameter of the water droplet that spray nozzle 480 is sprayed.The particle diameter of water droplet is during less than 10 μ m, exists water droplet to suspend and attached to the danger on the toilet seat 200 etc.Therefore, control part 405 is difficult to the occupation rate of control attached to basin 801 lip-deep water droplets.And, when for example the water droplet of Xuan Fuing is attached to user's buttocks, huckle etc., there is the danger that allows the user feel under the weather.On the other hand, the particle diameter of water droplet is during greater than 500 μ m, and there is the danger that flows down from the basin 801 surperficial vector product waters surface 805 in water droplet on sticking in basin 801 surfaces the time or in cohesion thereafter.Therefore, existence can not form and more effectively reduce attached to the moisture film of basin 801 lip-deep dirts, the danger of water droplet.Therefore, control part 405 is difficult to water droplet is gone up in control attached to basin 801 surfaces occupation rate.In addition, as average grain diameter described here, the size distribution of the Fraunhofer analytic method of the drop particle diameter during according to expression spraying has well been used Suo Te average (cumulative volume/total surface area).

To this, the average grain diameter of the water droplet that spray nozzle 480 is sprayed for example is about about 50～500 μ m.Therefore, can suppress the suspension of the water droplet that spray nozzle 480 sprayed.Thus, can suppress water droplet attached to toilet seat 200, user's buttocks or huckle etc.And, can suppress water droplet that spray nozzle 480 sprayed on sticking in basin 801 surfaces the time or in cohesion thereafter.Thus, can water droplet be stayed on basin 801 surfaces more expeditiously.And control part 405 is more easily controlled the occupation rate attached to basin 801 lip-deep water droplets.In addition, the average grain diameter of the water droplet that spray nozzle 480 is sprayed more preferably for example is about about 200 μ m.

Control part 405 can be controlled the spray amount of water droplet by the time of control spray nozzle 480 spraying water droplets.Control part 405 can more easily be controlled the occupation rates that go up water droplets attached to basin 801 surfaces by the particle diameter and the spray time of control spray nozzle 480 water droplet of being sprayed.About the particle diameter of water droplet, can adjust by the opening footpath and the flow of spray nozzle.In addition, consider that the user begins to the time that is sitting on the toilet seat 200 from entering the washroom, more preferably the spray time of water droplet is suppressed at for example below 10 seconds.Like this, can be before the user uses closet 800 basin 801 surfaces of wetting closet 800, suppress buttocks that water droplet is attached to the user, huckle etc.

In addition, the particle diameter of the sterilization water that spray nozzle 480 is sprayed is identical with the particle diameter of water droplet, for example is about about 10～1000 μ m.And the average grain diameter of the sterilization water that spray nozzle 480 is sprayed is identical with the average grain diameter of water droplet, for example is about about 50～500 μ m.

Secondly, with reference to accompanying drawing, a routine experimental result of the occupation rate of the water droplet that bright person implements is described.

Fig. 5, Fig. 6 (a) and Fig. 6 (b) are the ideographs of experiment condition of the occupation rate of the water droplet that is used to illustrate that the present inventor implements.

And Fig. 7 is the table as a result of illustration one this experimental result of example.

In addition, Fig. 8 is the chart of illustration one this experimental result of example.

In addition, Fig. 5 is the plane model figure when the top of the closet 800 of present embodiment is observed.Fig. 6 (a) is the plane model figure of observing from the top of the camera of test film.Fig. 6 (b) is the plane model figure of observing from the side of the camera of test film.

The present inventor, solution is sprayed to enamel surface as the basin 801 of the closet 800 of sanitary earthenware from spray nozzle 480 on, measured the occupation rate of the water droplet at measuring point A～H place shown in Figure 5.In this experiment, the occupation rate with the water droplet of the measuring point G among measuring point A～H is illustrated.

The present inventor at first puts test film 810 at measuring point G.The proterties on test film 810 surfaces is identical with the proterties on the enamel surface of basin 801.Therefore, test film 810 surfaces have the hydrophily surperficial identical with the enamel of basin 801.

Then, the present inventor is respectively with respectively solution being sprayed to the surface of the basin 801 of closet 800 from spray nozzle 480 in 1 second, 2 seconds, 3 seconds, 4 seconds, 5 seconds and 6 seconds.In order to test conveniently, the present inventor will have been caught the color (being green in this experiment) of regulation by the solution of spray nozzle 480 sprayings.By the solution of spray nozzle 480 spraying as shown below.

The spray solution that uses in this experiment comprises water, edible green (Japanese little storehouse food processing Co., Ltd. system).The manufacture method of spray solution is that the Xiang Shuili interpolation is edible green, makes the edible green 1(wt% that is).Then, in its solution, put into rotor (magnet), with electromagnetic type agitator (Japanese Pasolina system TR-300) speed is set at " 5 " and carries out 5 minutes stirring.

About the color of spray solution, use spectral photometric colour measuring meter (the Japanese Konika Minolta Sensing system CM-600d of Co., Ltd.) to confirm.That is, getting spray solution 100 microlitres (μ l) with micropipettor drips and drying in the approximate center of filter paper.The filter paper diameter that use this moment is 90mm.And the color of filter paper is white (for example, L * (D65)=97.25a * (D65)=-0.35b * (D65)=2.85).Then, with spectral photometric colour measuring instrumentation amount the color of approximate centre of dried filter paper.What be layered on measured filter paper (solution has dripped) behind overlapping 5 pieces of the filter paper (solution does not drip) that at this moment, will be identical with the filter paper of the spray solution that dripped has followingly implemented measurement.Then, making difference between base material (test film 810) and the spray solution is Δ L * (D65)=more than-5.8.For example, the color of the spray solution of use be L * (D65)=85.17a * (D65)=-23.17b * (D65)=6.50.

And the color of base material (test film 810) as shown below.That is, with spectral photometric colour measuring instrumentation amount the color of test film 810 approximate centre.For example, the color of the test film 810 of use be L * (D65)=90.97a * (D65)=-0.52b * (D65)=0.76.

Then, the present inventor has measured the occupation rate attached to the water droplet on the test film 810.Attached to the measuring method of the occupation rate of the water droplet on the test film 810 as shown below.

Shown in Fig. 6 (a) and Fig. 6 (b), the present inventor at first is placed in test film 810 and puts on the platform 820, will be radiated on the photographic plane from being arranged on to tilted roughly 35 ° the light of locational light source 830 of the top on test film 810 surfaces (photographic plane).In this experiment, from the center line 810c of test film 810, will shine from the light of 2 light sources 830 that are symmetric relation.Before will shining, measured the illumination of measuring point P1～P5 with luxmeter (Japanese HIOKI system 3423LUXHiTESTER) from the light of light source 830.This moment, the illumination of measuring point P1～P5 was 200～250 Luxs (lx).And in the time will shining from the light of light source 830 (when taking pictures), the illumination of measuring point P1～P5 is 5700～6000lx.

Then, the present inventor uses 1-4, the 7-26 of " Japanese KEYENCE corporate system DIGITAL MICROSCOPE VHX-100F " and basis " KEYENCE corporate system DIGITAL MICROSCOPE VHX-100F " user's manual to be taken pictures in test film 810 surfaces that water droplet adheres to.One for example shown in " the water droplet photo " of Fig. 7 of the photo of taking pictures.At this moment, the multiplying power with lens is set at " 5 times ".And, " light adjustment (LIGHT CONTROL) dial " that adjustment is arranged on adjustment Halogen lamp LED light quantity attached on " KEYENCE corporate system DIGITAL MICROSCOPE VHX-100F " before taking pictures is arranged on " minimum (MIN) ", " the brightness adjustment dial " of adjusting brightness be set on 12 the position, press " white balance button "." white balance button " is in order to bring into play the button of automatic adjustment color of image function.The area of taking pictures is 1875mm ²(50mm * 37.5mm).The pixel of the photo of taking pictures is 2,000,000 pixels.

Then, in the image of the water droplet of taking pictures,, therefore at first extracted the part (binary conversion treatment) of the briliancy of setting out owing to use the area measurement function of having used briliancy to measure the area of water droplet.Carried out the extraction of briliancy part according to 7-27, the 7-28 of " KEYENCE corporate system DIGITAL MICROSCOPE VHX-100F " user's manual.The extraction condition of briliancy as shown below.When the material of test film 810 was pottery, luminance range was set in " 0～190 ".When the material of test film 810 was resin, luminance range was set in " 0～170 ".Implemented the hydrophobic man-hour that adds on test film 810 surfaces, luminance range is set in " 0～150 ".Briliancy is extracted for example shown in " binaryzation " of Fig. 7 of image out.

Then, extract image out, carried out particle according to 7-31,7-32, the 7-33 of " KEYENCE corporate system DIGITAL MICROSCOPE VHX-100F " user's manual and removed and handle and hole is filled and handled about briliancy.The picture point number of setting during operation is decided to be " 30 ".Particle is removed and handled is the function that the particle of small size is removed in performance in the image of binaryzation.Hole fill to handle be in the image of binaryzation when producing immeasurable hole in the measured zone, make it can carry out the function of binary conversion treatment the hole filling.Then, the present inventor uses following formula to calculate occupation rate attached to water droplet on the test film 810.

The take pictures occupation rate (%) of area * 100=water droplet of the area ÷ of water droplet

One of the occupation rate of water droplet for example shown in " water droplet occupation rate (%) " and chart that Fig. 8 represents of Fig. 7 in each spray time.And one of the weight of water droplet for example shown in " water droplet weight (g) " and chart that Fig. 8 represents of Fig. 7 in each spray time.In addition, " the water droplet weight " in present specification be meant with water droplet from spray nozzle 480 after the spraying that the surperficial enterprising professional etiquette of the basin 801 of closet 800 is fixed time, remain in the weight of the water droplet on the test film 810.

Thus, water droplet occupation rate and water droplet weight increase along with the process of spray time.On the other hand, the water droplet occupation rate is that the boundary line turns to minimizing with about about 50%.Water droplet weight is that the boundary line turns to minimizing with about about 0.16.This be because, after the water droplet occupation rate reaches about 50%, stick in test film 810 lip-deep a part of water droplets and condense, even show water droplet spraying, much water droplets also can 805 landings of the vector product water surface.Thus, by in the about scope below 50% of water droplet occupation rate, water droplet being sprayed, can suppress the waste of water droplet.

According to this experimental result, the spray time preference of water droplet is according to appointment below 5 seconds.Thus, control part 405 can be controlled at the occupation rate attached to basin 801 lip-deep water droplets about below 50%.Therefore, distribute equably, can reduce the risk that water droplet does not adhere to dirt attached to basin 801 lip-deep parts attached to basin 801 lip-deep water droplets.Therefore, can reduce attached to basin 801 lip-deep dirts.

And the spray amount of control water droplet can realize water saving.Even spray nozzle 480 carries out spraying more than about 5 seconds with water droplet, the occupation rate of water droplet does not only rise, the danger that exists water droplet to begin to condense on the contrary.After the water droplet cohesion, beginning cohesion than water droplet before, the zone of not adhering to water droplet on basin 801 surfaces enlarges.Like this, begin than water droplet to increase before the cohesion in the risk that water droplet does not adhere to dirt attached to basin 801 lip-deep parts.To this, control part 405 is controlled at the spray time of water droplet for example about below 5 seconds, be controlled at about 50% when following attached to the occupation rate of basin 801 lip-deep water droplets, can shorten the spray amount of the spray time control water droplet of water droplet, reduce dirt simultaneously attached to basin 801 lip-deep risks.

In addition, aforesaid water droplet spray time and occupation rate are the illustrated example of this experimental result, but are not limited to this.As the front about as described in Fig. 1 and Fig. 2, the control part 405 of present embodiment is controlled the spray amount of water droplet by the time of control spray nozzle 480 spraying water droplets, the occupation rate attached to basin 801 lip-deep water droplets can be controlled at about 10～50% in the regulation zone on surface of basin 801.

Secondly, with reference to accompanying drawing, a routine experimental result of the nutrition residual rate that the present inventor is implemented describes.

In addition, Figure 10 is the chart of illustration one this experimental result of example.

The present inventor makes on the test film 810 of doubtful dirt attached to spray time with regulation or water droplet occupation rate, rinses out doubtful dirt then.The dirt composition that doubtful dirt contains ormal weight is saccharic, protein, lipid etc., makes the proterties of itself and dirt approximate.As Fig. 9 and shown in Figure 11, the water droplet occupation rate the when spray time of water droplet was 1 second is about about 10%.Water droplet occupation rate when the spray time of water droplet was 3 seconds is about about 30%.And the water droplet occupation rate the when spray time of water droplet was 5 seconds is about about 50%.These are identical with " water droplet occupation rate (%) " that Fig. 7 represents.

Then, take pictures in test film 810 surfaces that the present inventor will wash behind the doubtful dirt, and measured the nutrition residual rate on test film 810 surfaces.The present inventor has measured the nutrition residual rate according to the measurement of saccharic residual on test film 810 surfaces, protein, lipid.One for example shown in " surface picture " of Fig. 9 of test film 810 surface picture in each spray time or each water droplet occupation rate.And one of the nutrition residual rate on test film 810 surfaces for example shown in " nutrition residual rate (ppm) " and chart that Figure 10 represents of Fig. 9 in each spray time or each water droplet occupation rate.And, be used for remove under each spray time or each the water droplet occupation rate attached to the necessary time of doubtful dirt on the test film 810 for shown in Fig. 9 " removing the time (second) ".

According to this experimental result, even when occupation rate is about 10% left and right sides, the time of removing also only is 8 seconds, can fully remove in the scope of common Closet bowl cleaning time.And, even when having removed dirt, the also preferred nutrition residual rate that as far as possible suppresses to become the nutrient source of bacterium.According to chart shown in Figure 10, as can be known along with the water droplet occupation rate increases nutrition residual rate step-down.In addition, according to table as a result shown in Figure 9, the time of removing of increasing doubtful dirt along with the water droplet occupation rate shortens as can be known.

In this experiment, control part 405 is controlled at the spray time of water droplet about about 5 seconds, is controlled at approximately about 50% by the occupation rate with water droplet, and the nutrition residual rate is fully reduced.And, be used to as can be known to remove attached to required time of the doubtful dirt on the test film 810 the shortest when under this experiment condition about about 5 seconds being about 50% left and right sides of water droplet occupation rate at spray time.

Thus, control part 405 for example was controlled at the spray time of water droplet about about 5 seconds, in the time of will being controlled at about 50% left and right sides attached to the occupation rate of basin 801 lip-deep water droplets, can shortening the spray time of water droplet and suppress the spray amount of water droplet, suppress the nutrition residual rate on basin 801 surfaces simultaneously.

Secondly, with reference to accompanying drawing, describe attached to lip-deep effect of basin and effect suppressing dirt.

Figure 11 is the chart of the relation between illustration one routine water droplet occupation rate and the nutrition residual rate.

And Figure 12 is the comparison sheet for the test film that each test portion is described.

In addition, Figure 13 (a)～Figure 13 (c) is the plane model figure that removes the crude removal effect in order to illustrate.

Different and different attached to basin 801 lip-deep water droplet forms etc. according to the proterties on basin 801 surfaces.The water droplet occupation rate of the test film of the test portion that the present inventor is different to surface texture respectively (1)～(4) and the relation between the nutrition residual rate are measured.At first, make doubtful dirt, wash doubtful dirt then attached to having on the test film of identical proterties with basin 801 surfaces.Make the state of doubtful dirt attached on the test film time shown in Figure 12 " surface picture ".Doubtful dirt in this experiment is the dirt that has reproduced the composition ratio of actual dirt.And the present inventor is according to having remained in the measurement of concetration of test film proteins on surfaces, sugar and lipid after the flushing of doubtful dirt the nutrition residual rate.

The test film surface possess hydrophilic property of test portion (1).The test film of test portion (1) has and comprises that arithmetic average roughness Ra for example is the enamel layer (uncrystalline layer) on the surface of being called as about about 0.07 μ m " super even surface " etc.The following as can be known tendency of present inventor's investigation result: the flatness on surface is high more, and the hydrophily on surface is high more.

Contact angle θ at the water on the test film surface of test portion (1) for example is about about 38.4 ° (with reference to Figure 12)." contact angle " in present specification is meant on the surface of solids and the interface between the liquid surface of regulation, angle that the surface of solids and liquid surface form and the angle of promptly measuring in the hydraulic fluid side.And contact angle θ uses contact angle meter (Japan consonance surface chemistry Co., Ltd. system, automatic contact angle meter DM-500) to measure.Contact angle for example is about about 123.9 ° (with reference to Figure 12) in the water of the oleic acid on test portion (1) test film surface.Contact angle is that drip on the test film surface state of oleic acid is lowered into tank in the water, has measured the oleic acid contact angle on test film surface under this state.That is to say that " contact angle in the water " in present specification is meant the contact angle in water.

The test film surface possess hydrophilic property of test portion (2).On the test film surface of test portion (2), the SiO that have zircon (opacifying material), does not dissolve ₂Therefore, the hydrophily that had of the test film surface of test portion (2) is so high not as the hydrophily that the test film surface of test portion (1) is had.Contact angle θ at the lip-deep water of test film of test portion (2) for example is about about 43.5 ° (with reference to Figure 12).Contact angle θ for example is about about 106.0 ° (with reference to Figure 12) in the water of oleic acid on the test film surface of test portion (2).

The test film surface of test portion (3) has hydrophobicity." hydrophobicity " in present specification for example is meant to be compared with the pelvic surface of sacrum of the closet of implementing processings such as enamel on the surface and character that the compatibility of water is little or easily with the character of water ejection.Be formed with the overlay film of fluorine element on the enamel surface on the test film surface of test portion (3).Compare with the test film surface of test portion (1), test portion (2), the dirt that contains oil content has easily the lip-deep tendency of test film attached to test portion (3).The contact angle θ of the water on the test film surface of test portion (3) for example is about about 100.2 ° (with reference to Figure 12).Contact angle for example is about about 33.6 ° (with reference to Figure 12) in the water of the oleic acid on the test film surface of test portion (3).

The test film surface of test portion (4) is formed by acrylic resin.Therefore, the test film surface of test portion (4) has lipophile." lipophile " in present specification for example is meant with the pelvic surface of sacrum of the closet of implementing processing such as enamel on the surface compares the character big with the compatibility of fat or oil content.Compare with the test film surface of test portion (1), test portion (2), the dirt that contains oil content has easily the lip-deep tendency of test film attached to test portion (4).The contact angle θ of the water on the test film surface of test portion (4) for example is about about 72.3 ° (with reference to Figure 12).Contact angle for example is about about 2.5 ° (with reference to Figure 12) in the water of the oleic acid on the test film surface of test portion (4).

As shown in figure 11, the water droplet occupation rate increases, and then the nutrition residual rate reduces.This is because about as described in Fig. 1 and Fig. 2, by increasing the water droplet occupation rate, can not reduce the risk that doubtful dirt adheres to attached to the part on test film surface at water droplet as the front.That is to say, when the water droplet occupation rate increases, can reduce, alleviate the nutrition residual rate on test film surface attached to the lip-deep dirt of test film.When basin 801 masks of closet 800 have hydrophily, when promptly basin 801 masks of closet 800 have the surface texture identical with test portion (1) or test portion (2), the inhibition effect of nutrition residual rate in the water droplet occupation rate is about scope of about 20～50% time than higher.On the other hand, when basin 801 masks of closet 800 have hydrophobicity or lipophile, be basin 801 masks of closet 800 when having with the same surface texture of test portion (3) or test portion (4), the inhibition effect of nutrition residual rate in the water droplet occupation rate is about scope of about 10～40% time than higher.

Thus, on the surface of various closets, will be controlled at approximately about 10～50% attached to the occupation rate of basin 801 lip-deep water droplets by control part 405, it is residual to suppress nutrition.And, closet surface (surface of test portion (1) in this experiment) in performance with nutrition residual rate minimum, to be controlled at approximately about 30～50% attached to the occupation rate of basin 801 lip-deep water droplets by control part 405, it is residual further to suppress nutrition.

At this, shown in Figure 13 (a) and Figure 13 (b), even moisture film is not pre-formed on basin 801 surfaces, also can be crushed by dirt 521 and on basin 801 surfaces, spread attached to basin 801 lip-deep water droplets 511, combine with adjacent other water droplets 511 and form the moisture film 513 of suitable thickness.Even in this case, also can suppress dirt 521 attached on basin 801 surfaces.And, shown in the arrow A 1 of Figure 13 (c), can be by the clean water flushing of closet 800 and except that crude removal 521.

Even do not form moisture film, when the crushed moisture film that can form suitable thickness of water droplet, also can eliminate user's unplessantness displeasure.That is the situation of feeling bad below the user of use closet 800 exists: when for example carrying out " buttocks is cleaned " with hygienic washing device, the less and lighter dirt that disperses is attached on basin 801 surfaces.Less and lighter dirt like this falls and easily attached on 801 in the basin with inclination at closet 800 rear portions.Before using closet 800, will clean in the same manner in the method up to now that water spues with Closet bowl cleaning, the water droplet of this part can flow down, the risk height that dirt is residual.To this, in the present embodiment, even on 801 in foregoing basin, water droplet also can occupation rate in accordance with regulations disperse, foregoing dirt drops on 801 in basin and goes up on the water droplets that disperse, and water droplet is crushed and form moisture film, thereby can suppress less and lighter dirt attached on basin 801 surfaces.Therefore, can eliminate user's unplessantness displeasure.

Present inventor's investigation result is 2% when above attached to the occupation rate of basin 801 lip-deep water droplets 511 as can be known, can be crushed by dirt 521 and forms moisture film 513 attached to basin 801 lip-deep water droplets 511.But, because therefore the thin thickness of this moisture film can not be given full play to and suppress the dirt adhesion effect.Adhere to about suppressing dirt, the occupation rate of the water droplet more than 7% must be arranged as can be known.To this, illustrate further with reference to accompanying drawing.

Figure 14 (a) and Figure 14 (b) are in order to illustrate that the moisture film that the present inventor carries out forms the three-dimensional pattern figure that tests.

In addition, Figure 15 is the experimental result table of illustration one this experimental result of example.

At first, the present inventor has prepared base material 501 and has covered material 503.Base material 501 with cover material 503 and for example form by glass etc.Length and wide length when vertically observing the interarea that covers material 503 are respectively about about 18mm.The thickness that covers material 503 is about about 0.12～0.17mm.The weight that covers material 503 is about about 0.12 gram (g).

Shown in Figure 14 (a), the present inventor is dripped the water droplet 511 of regulation water droplet amount and it is adhered on base material 501 surfaces, will cover material 503 and be covered on the water droplet 511 as arrow A 2.Therefore, the present inventor judges whether water droplet 511 can be capped material 503 crushing and form moisture film 513 shown in Figure 14 (b).Its result of determination as shown in figure 15.

As shown in figure 15, the water droplet amount is 0.50 microlitre/square centimeter (μ l/cm ²) when above, water droplet 511 can be capped material 503 crushing and form moisture film 513 as can be known.The result of determination that Figure 15 represents is represented 1 the result of determination of water droplet 511 attached on the base material 501 time.At this, the water droplet amount is 0.20 μ l/cm ²Water droplet 511 at each unit area (cm ²) go up when having 3, be 0.60 μ l/cm attached to the water droplet amount on the base material 501 ²Can think that water droplet 511 can be capped material 503 crushing and form moisture film 513 this moment.

Figure 16 is the chart of the relation between illustration one routine water droplet occupation rate and the water droplet amount.

Attached to the form of test film, base material 501 lip-deep water droplets 511 according to the difference of the proterties (for example hydrophily, hydrophobicity etc.) of test film, base material 501 and difference.Therefore, the present inventor has discussed test film, and the water droplet occupation rate on the test film surface of test portion (4) and the relation between the water droplet amount of test film in test portion (1), test portion (3).

With compare on the surface attached to possess hydrophilic property, water droplet 511 is difficult to have hydrophobic diffusion into the surface.Therefore, the contact area that contacts with the surface of base material 501 grades of 1 water droplet 511 is than narrow with the surface contact area of possess hydrophilic property.

On the other hand, and compare attached to having on the hydrophobic surface, water droplet 511 is easily in the diffusion into the surfaces of possess hydrophilic property.Therefore, the contact area that contacts with the surface of base material 501 grades of 1 water droplet 511 is than with to have hydrophobic surface contact area big.

Thus, as shown in figure 16, the water droplet occupation rate of the water droplet amount of regulation attached on the test film surface of test portion (3) time is lower than the water droplet amount of its regulation water droplet occupation rate attached on the test film surface of test portion (1) time.And, the water droplet occupation rate of the water droplet amount of regulation attached on the test film surface of test portion (4) time is lower than the water droplet amount of its regulation water droplet occupation rate attached on the test film surface of test portion (1) time, than the water droplet occupation rate height attached on the test film surface of test portion (3) time.That is, when the test film with hydrophobic surface is compared with the test film on possess hydrophilic property surface, can under the lower state of water droplet occupation rate, form moisture film 513, can suppress dirt attached on basin 801 surfaces.

And the water droplet amount is 0.50 μ l/cm ²The time water droplet occupation rate water droplet 511 can be crushed and water droplet occupation rate when forming moisture film 513 is 0.7% on the test film surface of test portion (3), be 1.2% on the test film surface of test portion (4), be 2.0% on the test film surface of test portion (4).Thus, even as can be known on test film,, can be crushed by dirt and form moisture film attached to basin 801 lip-deep water droplets as long as the water droplet occupation rate is 2.0% when above with the surface that is called as " super even surface " and the test portion (1) on hydrophilic surface.That is to say, as can be known no matter the proterties on basin 801 surfaces how, as long as the water droplet occupation rate 2.0% with the time, can be crushed by dirt and form moisture film attached to basin 801 lip-deep water droplets.

That is, Figure 17 is the draw data of chart shown in Figure 11.

,, can be crushed by dirt and form moisture film about as described in Figure 16 as the front attached to basin 801 lip-deep water droplets as long as the water droplet occupation rate is 2% when above.

At this, as shown in figure 11,, more preferably further improve the water droplet occupation rate in order more to reduce the nutrition residual rate.In other words, suppress dirt attached to basin 801 lip-deep effects, more preferably further improve the water droplet occupation rate in order further to bring into play.Consider that the dirt ratio is easier on the test film surface attached to test portion (3) and test portion (4), as shown in figure 17, the water droplet occupation rate is when 0% brings up to about 10% left and right sides as can be known, and the nutrition residual rate reduces.That is to say that even as can be known on the test film of dirt than test portion that is easier to adhere to (3) and test portion (4), the water droplet occupation rate suppresses dirt and also can access further performance attached to basin 801 lip-deep effects when 0% brings up to about 10% left and right sides.

Thus, when the control part 405 of present embodiment will be controlled at about 10% left and right sides attached to the lower limit of the occupation rate of basin 801 lip-deep water droplets, suppress dirt and can access further performance attached to basin 801 lip-deep effects.

Figure 18 is the chart of the relation between illustration one routine water droplet occupation rate and the water droplet amount.

And Figure 19 is the chart of the relation between illustration one routine water droplet occupation rate and the water droplet density.

In addition, Figure 20 is the surface picture under the water droplet occupation rate of illustration regulation and the table as a result of binary image.

Figure 18 and chart shown in Figure 19 are the charts about the test film of test portion (1).Figure 20 is surface picture and the binary image about the test film of test portion (1).For " binaryzation ", as previously mentioned about Fig. 7.

As shown in figure 18, there is correlation between water droplet occupation rate and the water droplet amount.When the water droplet occupation rate increased, the effect that the water droplet amount increases and inhibition nutrition is adhered to increased.At this, as Figure 18 and shown in Figure 19, be 10～20% o'clock in the water droplet occupation rate, the water droplet amount increases and increases along with the water droplet occupation rate, and water droplet density is roughly saturated when being about 10% left and right sides in the water droplet occupation rate on the other hand, and the water droplet occupation rate reduces when surpassing about 20% left and right sides." water droplet density " in present specification is meant at each unit area (cm ²) the last water droplet number that exists.

That is to say that in the time of till the water droplet occupation rate arrives about about 20%, water droplet stably exists.On the other hand, the water droplet occupation rate surpasses at 20% o'clock, and for example water droplet can mutually combine to grow up to form and be the state of landing easily.

In the water droplet occupation rate is 10～20% o'clock, constantly increases attached to the amount of the lip-deep water droplet of test film, and but then, the number of water droplet but increases unlike the amount of water droplet.This is because the water droplet of being sprayed is coated on attached to above the lip-deep water droplet of test film, attached to the state (with reference to Figure 20) of size (amount) for increasing of the lip-deep water droplet of test film.In other words, for water droplet is covered with the whole state that exists of test film, is water droplet and on the test film surface, is the roughly state (with reference to Figure 11) of homogeneous dispersion.Therefore, under this state, can carry out the formation of the moisture film of suitable thickness expeditiously, can bring into play more expeditiously and suppress dirt attached to basin 801 lip-deep effects.

And the water droplet occupation rate was at 13～19% o'clock, even the water droplet occupation rate increases, stable state can be fixed and be to water droplet density also more.Do not observe the inter coagulation of a plurality of water droplet phase significantly.Therefore, can suppress because water droplet cohesion and the vector product water surface 805 flows down.And as shown in figure 18, the water droplet occupation rate is lower limit (the 0.50 μ l/cm that can form the water droplet amount of moisture film 13～19% o'clock water droplet amount ²) the water droplet amount more than 3 times.Therefore, can form more stable moisture film.

Secondly, with reference to accompanying drawing, the concrete example of the sterilization water generating unit 450 of present embodiment is described.

The sterilization water generating unit 450 of present embodiment is for for example having the electrolyzer unit of electrode.

As shown in figure 21, the sterilization water generating unit 450 of this concrete example portion within it has positive plate 451 and minus plate 452, by by control part 405 control energisings, can electrolysis flow through inner tap water.At this, contain chloride ion in the tap water.This chloride ion for example is included in the water source (for example, the water in underground water, reservoir water, river etc.) as salt (NaCl), calcium chloride (CaCl2) etc.Therefore, generate hypochlorous acid by its chloride ion of electrolysis.Its result is, become by the water of electrolysis (brine electrolysis) in sterilization water generating unit 450 and contains hypochlorous solution.

Hypochlorous acid is brought into play function as sterilization component, contain its hypochlorous liquid and be sterilization water can remove efficiently or decompose by ammonia, oil content etc. form dirty, maybe can carry out sterilization.

In addition, the sterilization water (brine electrolysis) that generates in sterilization water generating unit 450 also can be the liquid that contains metal ions such as silver ion, copper ion.Perhaps, the sterilization water that generates in sterilization water generating unit 450 also can be the solution that contains electrolytic chlorine, ozone etc.Perhaps, the sterilization water that generates in sterilization water generating unit 450 also can be acid water, alkaline water.Perhaps, sterilization water generating unit 450 is not limited to electrolyzer unit.That is, sterilization water also can be dissolving bactericide and bactericidal liquid and generate sterilization water in water.In these the solution, contain hypochlorous solution and have stronger sterilizing power.

As described above, according to present embodiment, the spray amount of the water droplet that control part 405 control spray nozzles 480 are sprayed, and will be controlled at about 10～50% in the regulation zone on basin 801 surfaces attached to the occupation rate of basin 801 lip-deep water droplets.Thus, distribute equably, can be reduced in the risk that water droplet does not adhere to dirt attached to basin 801 lip-deep parts attached to basin 801 lip-deep water droplets.Therefore, can reduce attached to basin 801 lip-deep dirts.And, can control the spray amount of water droplet and shorten the spray time of water droplet.And, to be controlled at about 10～50% attached to the occupation rate of basin 801 lip-deep water droplets by control part 405, even do not form moisture film on basin 801 surfaces, water droplet also can be spread on the basin surface by the dirt crushing, and combines the moisture film of formation suitable thickness with other adjacent water droplets.Thus, can suppress spray amount, suppress simultaneously attached to the lip-deep dirt of the basin of closet.

In addition, hypochlorous acid has and can decompose dirty function.Therefore, as previously mentioned, before using closet the occupation rate of control water droplet and suppressed dirt and adhered to after, can further after use closet, decompose nutritional labeling by inferior hydrochloric acid is sprayed, and further reduce the nutrition residual rate.Thus, can carry out desirable sterilization.As the opportunity of spraying, can be just left the back the user from closet, through any opportunity behind the official hour etc.

More than, embodiments of the present invention are illustrated.But the present invention is not limited to these and records and narrates content.As long as possess feature of the present invention, those skilled in the art to above-mentioned embodiment suitably in addition the technology after the design alteration be also contained in the scope of the present invention.For example, the shape of each key element that toilet-flushing apparatus 10 grades are possessed, size, material, configuration etc. and spray nozzle 480 form etc. is set, all be not limited to illustrated content, can suitably change.

In addition, as long as technical feasible, each key element that aforementioned each embodiment possessed can make up, as long as comprise feature of the present invention, the technology that has made up these contents is also contained in the scope of the present invention.
