As described above, constituting the spray nozzle device 800 of present embodiment.

The control of the ＞ cleaning parts of ＜ 6 and action

Hereinafter, control and the action of the cleaning part of the clean washing apparatus of present embodiment are illustrated.

First, the basic action of cleaning part 500 is illustrated referring to Fig. 6.

First, the running water flowed in water supply pipe is supplied to as rinse water from water supply connector 510.Enter And, sealing magnetic valve 514 is opened, so as to supply rinse water to secondary water tank 600.Now, flowed in rinse water supply line 690 The flow of rinse water remain constant by constant flow rate valve 513.In addition, the driving of sealing magnetic valve 514 by control unit 130 according to distant The operation of control device 400 and operating portion 210 is controlled.

Then, it is conveyed to the rinse water of secondary water tank 600 to be accumulated in secondary water tank 600, and is fed to heat exchanger 700 With the water pump 516 for constituting injection flow rate change portion.And then, by driving water pump 516, rinse water is conveyed via flow regulating valve 517 To spray nozzle device 800.In addition, the driving of water pump 516 is carried out by control unit 130 according to the operation of remote control 400 and operating portion 210 Control.

Then, the driving of control unit 130 water pump 516.Moreover, flat plate-like heater of the control unit 130 to heat exchanger 700 702 are powered, and start to heat rinse water.Now, control unit 130 according to enter water temperature sensor 630 and go out hot water temperature sensing The detection information of device 730, controls the energization to flat plate-like heater 702.Moreover, control unit 130 is controlled so that rinse water Maintain by the temperature of the setting of hot water temperature's switch 231 of operating portion 210.

Then, control unit 130 controls cutting for flow regulating valve 517 according to the operation information of operating portion 210 and remote control 400 Change.That is, flow regulating valve 517 is switched to the huckle cleaning nozzle 831 of spray nozzle device 800, washer jet for women by control unit 130 832nd, any one in nozzle cleaning portion 833, and supply rinse water.Thus, from huckle cleaning ejiction opening 834, for women clear Any one ejiction opening washed in ejiction opening 836, nozzle cleaning ejiction opening 838 sprays rinse water.

Hereinafter, pair control related to the secondary water tank 600 of present embodiment, especially water level detecting and flow detection are carried out Explanation.

First, the control of the cleaning part 500 when initially using of the clean washing apparatus of present embodiment is illustrated using Figure 29 System.

Figure 29 is the timing diagram of cleaning part when initially using of the clean washing apparatus.In addition, suitable when initially using Implement what is reused after drain operation in situation about being used for the first time after being set in clean washing apparatus or in order to prevent from freezing Situation etc. does not stockpile the state of rinse water in cleaning part 500.

As shown in figure 29, in moment P1, user is to the cleaning switch of operating portion 210 or remote control 400 (for example, buttocks Cleaning switch 221 or 410) operated.Thus, control unit 130 is powered to sealing magnetic valve 514, starts in secondary water tank 600 The supply of rinse water, meanwhile, start the driving of level detection sensor 620.In addition, after moment P14 huckle cleaning stops Cleaned after end, supply rinse water to secondary water tank 600, water is continued untill level detection sensor 620 detects upper limit water level The driving of level detection sensor 620.

Then, in moment P2, when level detection sensor 620 detects upper limit water level, the time started of control unit 130 surveys Amount.And then, P3 at the time of have passed through the defined time stops the energization of sealing magnetic valve 514 and stops the supply of rinse water.

In addition, in the present embodiment, stopping being powered after such as 2 seconds of upper limit water level are detected.The reason is that Turn into full water state in P2 at the time of detecting upper limit water level, generally pair water tank 600 and in heat exchanger 700.Here, continue into Row is conveyed during unnecessary 2 seconds.Thus, more reliably make rinse water full of in heat exchanger 700 and water pump 516, exclude heat The air waited in exchanger 700.As a result, being more reliably prevented from the dry combustion method of the heat exchanger 700 as caused by residual air, carry High security and durability.Similarly, the water pump 516 that rinse water reliably can be transported into composition injection flow rate change portion is formed For full water state.Thereby, it is possible to start the water pump 516 of full water state, rinse water is more reliably sent to spray nozzle part 820.

Then, P3 at the time of stopped the energization of sealing magnetic valve 514, control unit 130 starts the drive to water pump 516 It is dynamic.Meanwhile, flow regulating valve 517 is driven, the supply of rinse water is started to the huckle cleaning stream 835 of such as spray nozzle part 820.Now, By the driving of water pump 516, the water level decreasing of the rinse water in secondary water tank 600, in moment P4, level detection sensor 620 is solved Except the detection to upper limit water level.Then, in moment P4, control unit 130 starts the driving to heat exchanger 700.That is, water level is passed through The detection of reduction, is able to confirm that out whether water pump 516 is normally carried out action.Thereby, it is possible to prevent the heat exchangers such as dry combustion method 700 Abnormal temperature rises.

Supply to the rinse water of huckle cleaning stream 835 and sprayed from huckle cleaning ejiction opening 834.The rinse water of ejection passes through Spray opening 844 and contact the inner surface for clasping portion 816 for the end for being arranged at support 810 and reflect.Thus, cleaning nozzle The outer surface of cover 840.Hereinafter, cleaning action is referred to as " preceding cleaning ".In addition, preceding cleaning is continued to from heat exchanger 700 Go out hot water temperature reach such as 25 DEG C rise after 2 seconds at the time of P5 untill.

Then, at the end of moment P5, preceding cleaning, control unit 130 starts the washer jet drive division to spray nozzle device 800 860 driving.Moreover, making spray nozzle part 820 advance from reception position to huckle cleaning position.Now, from reception position to stern During portion's cleaning positions movement, the switching flow regulating valve 517 of control unit 130 supplies rinse water to nozzle cleaning stream 839.Supply Rinse water to nozzle cleaning stream 839 is ejected into the inside of nozzle casing 840 from nozzle cleaning ejiction opening 838.The cleaning of ejection Water flows out to the outside of nozzle casing 840 from discharge outlet 845 after the inner surface of nozzle casing 840 has been cleaned.During this period, nozzle Rinse water after portion 820 is heated by heat exchanger 700 is heated.Thus, can be by cold water during the huckle cleaning implemented thereafter Ejection prevent trouble before it happens, eliminate user unplessantness displeasure.

Then, P6 at the time of spray nozzle part 820 reaches huckle cleaning position, the switching flow regulating valve 517 of control unit 130 starts Rinse water is supplied to huckle cleaning stream 835.Supply is to the rinse water of huckle cleaning stream 835 from huckle cleaning ejiction opening 834 Spray.Moreover, rinse water cleans the part of user by ejection opening 844.For example used in addition, huckle cleaning is proceeded to Person is carried out at the time of the operation of cleaning stopping untill P11.

Now, control unit 130 is in the driving to heat exchanger 700, according to entering water temperature sensor 630 and go out hot water temperature The detection data of degree sensor 730 are controlled so that the temperature of rinse water turns into set temperature.

In addition, when continuing the driving of water pump 516 from moment P3, the water level decreasing of the rinse water in secondary water tank 600.Cause This, P7 at the time of level detection sensor 620 detects lower limit water level, control unit 130 starts logical to sealing magnetic valve 514 Electricity, and supply rinse water.Hereafter, control unit 130 continues to be powered to sealing magnetic valve 514, until level detection sensor 620 is examined P8 at the time of measuring upper limit water level.

P8 at the time of upper limit water level is detected, control unit 130 stops the energization of sealing magnetic valve 514, and when starting Between measure.And then, measurement at the time of level detection sensor 620 detects lower limit water level next time untill P9 when passing through Between.

Then, P9 at the time of lower limit water level is detected, elapsed time measured by the computing of control unit 130 and from the upper limit Water level calculates flow to the water (such as 65cc) of lower limit water level.The P10 at the time of computing of flow calculation process terminates, when In the case that the flow set according to each cleaning strength has differences with the flow sprayed, the adjustment water pump 516 of control unit 130 Output, corrects the flow of rinse water.

Then, P11, control unit at the time of the operation for the cleaning stopping that operating portion 210 or remote control 400 are carried out in user 130 stop the energization to water pump 516 and heat exchanger 700.Meanwhile, the washer jet of the driving spray nozzle device 800 of control unit 130 drives Dynamic portion 860, makes spray nozzle part 820 be retreated from huckle cleaning position to reception position.

P12 at the time of spray nozzle part 820 backs to reception position, control unit 130 stops to washer jet drive division 860 Driving.Meanwhile, control unit 130 drives water pump 516 and heat exchanger 700 again, starts " the rear cleaning " in cleaning nozzle portion 820.

Then, P13 at the time of have passed through the defined time, control unit 130 stops to water pump 516 and heat exchanger 700 Driving.Thus, " rear cleaning " terminates.

Then, P13 at the time of the rear cleaning of spray nozzle part 820 terminates, control unit 130 is logical to sealing magnetic valve 514 again Electricity, rinse water is supplied to secondary water tank 600.Then, P14 at the time of level detection sensor 620 detects upper limit water level, control Portion 130 stops being powered to sealing magnetic valve 514, terminates a series of control of huckle cleaning.Thus, it is upper in secondary water tank 600 Restrict water supply under the full water state of position, cleaning part 500 is holding state.

As described above, performing the control of cleaning part when initially using of the clean washing apparatus 100 of present embodiment.

Hereinafter, illustrated using Figure 30 present embodiment clean washing apparatus 100 it is usually used when cleaning part control System.

Figure 30 be the clean washing apparatus it is usually used when cleaning part timing diagram.In addition, suitable when usually used Clean washing apparatus under holding state when by implementing initially to use in the past implements the situation of cleaning action.

Here, the cleaning part when control of cleaning part during usually used shown in Figure 30 and initial shown in Figure 29 use The difference of control be that P20 at the time of cleaning operation is carried out, secondary water tank 600 is in full water state；And control Portion 130, which is stored with, has had been carried out initial situation about using.

First, as shown in figure 30, in moment P20, secondary water tank 600 is under the holding state of full water state, is used Person operates to the cleaning switch (for example, huckle cleaning switch 221 or 410) of operating portion 210 or remote control 400.Thus, control Portion 130 processed is powered to water pump 516, starts to supply rinse water to defined spray nozzle part.Meanwhile, according to having had been carried out initial operation The data storage of control, starts the energization to heat exchanger 700.

And then, start simultaneously at " preceding cleaning " action of spray nozzle device 800.Moreover, control unit 130 starts water level detecting sensing The driving of device 620.

That is, in situation when initially using illustrated by Figure 29 with the case of, being grasped from cleaning has been carried out Control at the time of work untill at the time of the energization of heat exchanger 700 starts is different.In addition, from starting to spray nozzle device 800 Driving at the time of P5 after control, effect and act same with Figure 29, therefore omit the description.

As described above, the clean washing apparatus of present embodiment is detected by being arranged at the level detection sensor of secondary water tank The change of the water level of rinse water, and flow is calculated by computing.Thus, without setting the special of detection flows in addition in cleaning part Flow sensor etc..As a result, can simplify the structure of cleaning part, cost of implementation is cut down.

In addition, the clean washing apparatus of present embodiment initial in use, after the full water state of secondary water tank is detected, Continue the time as defined in water flowing.Meanwhile, after being driven to water pump, and then level detection sensor detects upper limit water level In the case of releasing, start to be powered to heat exchanger.Thereby, it is possible to judge that reliably heat exchanger has supplied rinse water. As a result, the dry combustion method of heat exchanger can be prevented.Therefore, compared to usually using flow sensor prevent dry combustion method structure and Speech, can be formed as simple structure.As a result, can be cleaned with being realized with a low cost the health with high security and reliability Device.

As described above, performing the control of the cleaning part of the clean washing apparatus in present embodiment, effect and acting.

Control, effect and the action of ejections towards toilet seat inner surface of the ＞ of ＜ 7 based on spreader nozzle

Hereinafter, the direction of the spreader nozzle based on the clean washing apparatus in present embodiment is sat using Figure 31 to Figure 34 Ejection control, effect and the action of closet inner surface are illustrated.

Figure 31 is the stereogram of the outward appearance for the spreader nozzle for showing the clean washing apparatus.Figure 32 is the vertical of the spreader nozzle Sectional view.Figure 33 is the rotation of the ejiction opening for the set location and spreader nozzle for showing the spreader nozzle in the clean washing apparatus The top view of gyration.Figure 34 is the output in the corresponding injection flow rate change portion of the anglec of rotation for the ejiction opening for showing the spreader nozzle And the chart of the rotary speed of spreader nozzle drive division.

As shown in Figure 31 and Figure 32, spreader nozzle 550 is by spreader nozzle drive division 550a, main part 550c, rotation Nozzle 550d etc. is constituted.Spreader nozzle drive division 550a carries out rotation driving such as being constituted by motor to swivel nozzle 550d. Main part 550c has inlet fluid path 550b and ingate 550h, the cleaning that the foam generating unit 560 shown in Fig. 6 is generated Foam and rinse water etc. are supplied to swivel nozzle 550d.Moreover, main part 550c will internally pass through O-ring 550e, O-ring 550f and remained and rotate freely by the swivel nozzle 550d of sealing.Swivel nozzle 550d drives via axle 550n and spreader nozzle Dynamic portion 550a is fitted together to, and is driven in rotation.

As described above, constituting the spreader nozzle 550 of present embodiment, and act as follows.

First, Fig. 6 foam generating unit 560 is generated rinse water or cleaning main body of the foam from spreader nozzle 550 Part 550c inlet fluid path 550b is supplied to.The rinse water or cleaning foam of supply are opened from around swivel nozzle 550d If, main part 550c multiple ingate 550h are supplied in swivel nozzle 550d.Hereafter, from swivel nozzle 550d spray The inner surface for exporting 550u towards toilet seat sprays.

As shown in figure 33, spreader nozzle 550 is configured at the position of the ratio center of main body 200 on the right side.Its reason be in order to The preferred dispositions such as the huckle cleaning nozzle 831 of body local will be cleaned in center.Therefore, spreader nozzle 550 is configured at left and right and appointed Anticipate a side rather than center.In addition, above-mentioned configuration can certainly be made opposite.

Then, ejection control of the reference picture 6 to the cleaning foam of spreader nozzle 550 etc. is illustrated.

It is non-to take a seat state and toilet seat is in the case of closed mode, spreader nozzle to user in addition, following 550 ejection control is illustrated.

First, when user enters toilet, the control unit 130 of clean washing apparatus 100 is sensed by human testing Device 450 detects the entrance of people.Meanwhile, control unit 130 starts to constitute the operating of the water pump 516 in injection flow rate change portion.Moreover, control Open the open and close valve 530a of branch flow passage 530 in portion 130.

In this case, carry out to huckle cleaning nozzle 831, washer jet for women 832 or nozzle cleaning portion 833 etc. The flow regulating valve 517 of the switching of stream is closure state.Therefore, the rinse water of automatic heat-exchanger 700 is carried out via the He of branch flow passage 530 Constitute the check-valves 531 of foam generating unit 560, bubble chamber 532 and be supplied to spreader nozzle 550.The rinse water of supply is from sprinkling The ejiction opening 550u of nozzle 550 is ejected into toilet seat inner surface.

Now, control unit 130 is driven to the spreader nozzle drive division 550a of spreader nozzle 550, to swivel nozzle 550d ejiction opening 550u carries out rotation driving.Thus, from the rinse water or cleaning foam of ejiction opening 550u ejections to toilet seat The complete cycle sprinkling of device inner surface, in toilet seat inner surface formation moisture film or foam film.

In addition, as shown in figure 33, from distances of the ejiction opening 550u of spreader nozzle 550 to toilet seat inner surface according to sprinkling The anglec of rotation direction of nozzle 550 and it is different.

That is, in the case of the anglec of rotation change for the spreader nozzle 550 for making to be configured at above-mentioned position, as shown in figure 33, When the ejiction opening 550u of spreader nozzle 550 anglec of rotation is 160 °, from ejiction opening 550u to the distance of toilet seat inner surface Most long (remote).On the other hand, when the ejiction opening 550u anglec of rotation (is rotated obtained by 180 ° for 340 ° equivalent to from above-mentioned 160 ° Position) when, it is most short (near) to the distance of toilet seat inner surface from ejiction opening 550u.

Therefore, as shown in figure 34, control unit 130 is controlled so that according to the ejiction opening 550u of spreader nozzle 550 rotation Gyration, changes output and the spreader nozzle drive division 550a rotary speed for the water pump 516 for constituting injection flow rate change portion.

Hereinafter, output and the spreader nozzle drive division of water pump 516 are changed to the anglec of rotation according to spreader nozzle 550 The control of 550a rotary speed is illustrated.

First, control unit 130 detects user by human body detection sensor 450 and enters toilet.Thus, control unit 130 start above-mentioned control.

Then, control unit 130 changes composition injection flow rate according to the ejiction opening 550u of spreader nozzle 550 anglec of rotation The output of the water pump 516 in portion changes in the range of from " height " to " low " as shown in Figure 34 hypomere and sprays cleaning bubble Foam.

Specifically, it is attached for 160 ° in the anglec of rotation of the distance to toilet seat inner surface most long (remote) shown in Figure 33 Closely, control unit 130 makes the output of water pump 516 larger (height).On the other hand, in the distance to toilet seat inner surface most short (near) The anglec of rotation is that control unit 130 makes the output of water pump 516 smaller (low) near 340 °.

In addition, control unit 130 in the anglec of rotation more than 0 ° and less than in the range of 160 °, make the output stage of water pump 516 Property or continuously from it is " low " change turn to " height ".Similarly, control unit 130 in the anglec of rotation more than 160 ° and less than 340 ° In the range of, make the output of water pump 516 periodically or continuously from " height " become to turn to " low ".Thus, according to from ejiction opening 550u to toilet seat inner surface distance, it is uniform in defined altitude range in the range of the complete cycle of toilet seat inner surface Spray rinse water or cleaning foam in ground.

In addition, in Figure 34, being shown by taking the action of the spreader nozzle 550 with rotationally constrained portion described later as an example. Therefore, show in the range of the anglec of rotation is 0 ° to 340 °, the figure of the exporting change of water pump 516.But, do not set using In the case of the structure for putting rotationally constrained portion, naturally it is also possible to make in the scope for the rotation 1 week that the anglec of rotation is 0 ° to 360 ° The output of water pump 516 changes.

That is, control unit 130 according to the anglec of rotation of spreader nozzle 550, i.e. ejiction opening 550u and toilet seat inner surface away from From the spray volume (and spouting velocity) of cleaning foam of the control from ejiction opening 550u.

More specifically, to before the toilet seat at the ejiction opening 550u maximum distances position with spreader nozzle 550 In the case that side sprays cleaning foam, water pump 516 is output as " height ", spray cleaning foam most surging head.Thereby, it is possible to Cleaning foam is set fully to reach the inner surface in front of toilet seat.

On the other hand, to the toilet seat rear at the ejiction opening 550u minimum distances position with spreader nozzle 550 In the case of spraying cleaning foam, water pump 516 is set to be output as " low ", most weak tendency head ground sprays cleaning foam.Thereby, it is possible to incite somebody to action A problem that resilience for cleaning foam, prevents trouble before it happens.

Moreover, using it is preceding in advance to toilet seat inner surface integrally spray rinse water or cleaning foam and formed moisture film or Foam film.Thereby, it is possible to which the attachment of dirt when using is prevented trouble before it happens.

As described above, control unit 130 makes the defeated of water pump 516 according to the ejiction opening 550u of spreader nozzle 550 anglec of rotation Go out to change.Thereby, it is possible to reliably be reached apart from different toilet seat inner surfaces with causing rinse water or cleaning foam Front, side, the mode at rear sprayed.As a result, can toilet seat inner surface wide scope formation moisture film or Foam film, suppresses the attachment of dirt.

In addition, in the above-described embodiment, set by causing the output of water pump 516 on the basis of average rank " medium " It is illustrated exemplified by the structure of fixed " height " and " low ", but not limited to this.For example, being configured to make the output of water pump 516 Average rank " medium " itself it is higher or relatively low, so as to change reference grade.In such a situation it is preferred that will adjustment The grade switching switch of average rank is arranged at operating portion 210 or remote control 400.Thus, even in being provided with hygienic cleaning In the case that size of toilet seat 110 of device 100 etc. is different, also toilet seat can be reached to cause rinse water or clean foam The mode of the complete cycle of device inner surface is sprayed.Moreover, the cleaning foam for being sprayed onto toilet seat inner surface can be changed arbitrarily (with respect to the horizontal plane) height and position.As a result, can be more reliably in whole toilet seat inner surface formation moisture film or bubble Foam film, suppresses the attachment of dirt.

In addition, in the above-described embodiment, with the anglec of rotation of the control unit 130 according to the ejiction opening 550u of spreader nozzle 550 Degree makes to be illustrated exemplified by the ejection control that the output of water pump 516 changes, but not limited to this.For example, except water pump 516 Output change outside, can be controlled into as shown in Figure 34 epimere according to the ejiction opening 550u's of spreader nozzle 550 The anglec of rotation makes spreader nozzle drive division 550a rotary speed change.

As described above, by making the output of water pump 516 change, making rinse water or cleaning the impetus of the ejection of foam Change.Thereby, it is possible to make cleaning foam reliably be sprayed onto toilet seat inner surface farther out, and effectively suppress cleaning bubble Resilience of the foam at nearer toilet seat inner surface.

Now, the anglec of rotation always according to ejiction opening 550u becomes spreader nozzle drive division 550a rotary speed Change.Thereby, it is possible to make rinse water or cleaning foam to the sprinkler discharge density of the complete cycle of toilet seat inner surface evenly.

That is, in the case where making the ejiction opening 550u of spreader nozzle 550 with certain rotary speed rotation, with toilet seat The distant position of inner surface, the sprinkler discharge density for cleaning foam is small.On the other hand, with the distance of toilet seat inner surface compared with Near position, the sprinkler discharge density for cleaning foam is big.

In addition, even in the output of above-mentioned water pump 516 is changed and spray cleaning foam in the case of, can also make The sprinkler discharge density of cleaning foam becomes uniform to a certain extent.

But, when becoming spreader nozzle drive division 550a rotary speed according to the anglec of rotation of spreader nozzle 550 When changing and spraying cleaning foam, sprinkler discharge density can be made evenly.In other words, rinse water or cleaning foam can be made from sprinkling The ejiction opening 550u of nozzle 550 sprays, and is sprayed in the range of the complete cycle of toilet seat inner surface with sprinkler discharge density evenly.

Generally, in the case of rotation speed constant, as shown in figure 33, towards the ejiction opening 550u with spreader nozzle 550 The anglec of rotation of maximum distance be 160 ° nearby, i.e. toilet seat front sprinkling rinse water or cleaning foam dispersion, spray Density is small.Therefore, as shown in Figure 34 epimere, in the case where foam etc. will be cleaned to ejection in front of toilet seat, spreader nozzle 550 rotary speed is most slow (low speed), thus, make the ejiction opening 550u of spreader nozzle 550 by toilet seat front adjacent when Between it is elongated, uprise sprinkler discharge density.

On the other hand, direction and the anglec of rotation of the ejiction opening 550u minimum distances of spreader nozzle 550 are near 340 °, i.e. Cleaning foam that the rear of toilet seat sprays etc. is concentrated, and sprinkler discharge density is big.Therefore, as shown in Figure 34 epimere, spreader nozzle 550 Rotary speed it is most fast (high speed).Thus, the ejiction opening 550u of spreader nozzle 550 is made to pass through the when anaplasia near toilet seat rear It is short, make sprinkler discharge density step-down.

As a result, the rinse water that can make to be sprayed onto toilet seat inner surface or clean the sprinkler discharge density of foam independent of Become to the anglec of rotation uniform (eliminating uneven).Therefore, it is possible to more effectively suppress in the range of the complete cycle of toilet seat inner surface The attachment of dirt.

As described above, control unit 130 drives spreader nozzle according to the ejiction opening 550u of spreader nozzle 550 anglec of rotation Portion 550a rotary speed changes.For example, when be spreader nozzle 550 ejiction opening 550u direction towards with toilet seat In the case of the anglec of rotation in front of the longer toilet seat of the distance on surface, make spreader nozzle drive division 550a rotary speed compared with Small (low speed).On the other hand, when be ejiction opening 550u direction towards the toilet seat shorter with the distance of toilet seat inner surface after In the case of the anglec of rotation of side, make spreader nozzle drive division 550a rotary speed larger (high speed).

Thereby, it is possible to equably by rinse water or cleaning foam to front, the side apart from different toilet seat inner surfaces Side, rear are sprayed without the inequality of sprinkler discharge density.As a result, by be formed uniformly on toilet seat inner surface moisture film or Foam film, can more effectively suppress the attachment of dirt.

Here, in the present embodiment, control unit 130 is controlled so that detected when by human body detection sensor 450 It is fashionable to entering for people, spray rinse water or cleaning foam in advance from spreader nozzle 550 to toilet seat inner surface.Specifically, Control unit 130 is controlled so that swivel nozzle 550d is for example rotated after 2 weeks by spreader nozzle drive division 550a and is stopped automatically Only.Thus, before user uses lavatory, in toilet seat inner surface formation moisture film or foam film.As a result, can effectively press down The attachment of the dirt in toilet seat inner surface when system is used.

In addition, in the above-described embodiment, illustrating spraying cleaning bubble using preceding making spreader nozzle 550 rotate 2 weeks The example of foam etc., but not limited to this.For example, it may be following structure：Cleaning foam to cause sprinkling etc. is fully reached and sat The defined number of turns of closet inner surface or defined time are sprayed and stopped.

In addition, in the above-described embodiment, the direction of rotation of spreader nozzle 550 does not have specifically mentioned, to cause rotation spray Mouth 550d is illustrated exemplified by rotating the structure of 2 weeks to a direction, but not limited to this.It is disconnected Make the swivel nozzle 550d of spreader nozzle 550 in the structure of defined rotating range reciprocating rotary.

Generally, the swivel nozzle 550d for making spreader nozzle 550 is being used only towards any one side in right or left In the case of the structure for carrying out integral cycle rotating, rinse water or the sprinkling direction for cleaning foam are equidirectional all the time.

But,, will from the two directions of positive and negative rotation by reciprocating action in the case where rotating back and forth to and being sprayed Foam etc. is cleaned to spray to toilet seat inner surface.Thus, the generation in so-called sprinkling omission portion tails off.It is clear therefore, it is possible to realize Wash the sprinkling that foam etc. evenly reaches toilet seat inner surface.As a result, can be pressed down by less sprinkling number of times (time) The attachment of dirt processed.In addition, above-mentioned reciprocating rotary is not limited to reciprocal 1 time, it is of course possible to be set as reciprocal 2 times or reciprocal 3 times Deng repeatedly.

Specifically, as shown in Figure 34 epimere, first, the swivel nozzle 550d of spreader nozzle 550 is made from equivalent to seat 0 ° of the anglec of rotation of the front side of closet rotates forward (for example, clockwise) for 340 ° to the anglec of rotation, and temporarily ceases.Hereafter, Swivel nozzle 550d is reversely rotated (for example, counterclockwise) for 0 ° from 340 ° of the anglec of rotation to the anglec of rotation, stop after reciprocating rotary Only.

In this case, set and the swivel nozzle 550d of spreader nozzle 550 scopes that can be rotated are limited to from rotation 0 ° of angle to 340 ° of the anglec of rotation, for example as machinery retainer rotationally constrained portion (not shown).

Specifically, the projection and main part of the part of the periphery that is formed at swivel nozzle 550d are for example passed through 550c rotating limiting walls constitute rotationally constrained portion (not shown).By the structure, when projection rotate and with rotating limiting walls thing When reason is abutted, the action for the swivel nozzle 550d to be rotated is limited.That is, the motor for constituting spreader nozzle drive division 550a passes through Abut and skid and dally.Thus, swivel nozzle 550d is configured to carry out the rotation more than scope that can rotate.

As described above, setting the rotationally constrained portion of limitation rotating range on the spreader nozzle 550 of said structure, make sprinkling Nozzle 550 do not limited by rotationally constrained portion can rotate in the range of reciprocating rotary.Moreover, from reciprocal opposite direction, I.e. two directions of positive and negative rotation are sprayed onto toilet seat inner surface by foam etc. is cleaned.Thus, the production in so-called sprinkling omission portion Change few.Therefore, it is possible to realize that cleaning foam etc. evenly reaches the sprinkling of toilet seat inner surface.As a result, can be with less Sprinkling number of times (time) suppress dirt attachment.

In addition, the spreader nozzle 550 of said structure can will be configured the motor-driven of spreader nozzle drive division 550a The position that swivel nozzle 550d projection is abutted with rotationally constrained portion is identified as spreader nozzle drive division 550a rotation position all the time The origin put.That is, the deviation of the origin caused by the reciprocating action for the swivel nozzle 550d that spreader nozzle 550 will not be produced.By This, it is possible to increase is relative to the rotary angle position precision of toilet seat inner surface.Therefore, it is possible to make relative to toilet seat inner surface Defined position position deviate etc. deviation it is minimum.Steeped as a result, be able to will be cleaned with appropriate ejection output, rotary speed Foam etc. is sprayed onto the accurate rotary angle position of toilet seat inner surface from the ejiction opening 550u of spreader nozzle 550.

In addition, in the above, illustrating physically to limit the structure of the rotating range of spreader nozzle 550, but do not limit In this.Deviate in the position of the origin of spreader nozzle 550 in the case of not being a problem, merely can be driven by spreader nozzle Portion 550a carries out positive and negative rotation action.Thus, it is not necessary to rotationally constrained portion and can realize that positive and negative rotation, a direction rotate Etc. various action.As a result, the action being more suitable for can be realized according to the situation of the dirt of toilet seat inner surface etc..In the feelings Under condition, preferably the anglec of rotation of reversion is set as near 160 °, and make rotary speed gradually slack-off in its vicinity.Thus, energy Enough mitigate load during spreader nozzle drive division 550a reversion.
