When being arranged at above-mentioned driving mechanism in the unit box 30, in this form, at first connecting wheel 40, actuation gear 50, toilet cover are relatively rotated axle 20 with the damping case 220 of oil damping device 22 and carry out coaxial shape setting, and the 3rd of reducing gear train is taken turns 72 is that to take turns 73 be that final gear and idler gear 8 are vertically arranged from the bottom to top towards actuation gear 50 directions in this order and be provided with to leading portion gear, the 4th.For this reason, as can be seen from Figure 5, the 3rd take turns 72 be leading portion gear, the 4th take turns 73 be final gear, idler gear 8, actuation gear 50 and connecting wheel 40 be set at its width dimensions when rotatingshaft 20 axial directions are observed, with space that the outside dimension of damping case 220 equates substantially in.
Therefore, in the standing portion 10a of narrow width when the axial direction of rotatingshaft 20 is observed on unit box 30, can taking in the 4th, to take turns 73 be the foundation end of final gear, idler gear 8, actuation gear 50, connecting wheel 40, rotatingshaft 20 and toilet cover with oil damping device 22.Just because of this, as unit box 30, just can adopt when the axial direction of rotatingshaft 20 is observed two sides of visible its standing portion 10a to leave the shape of the L font in space.Thus, when rotatingshaft 20 connect toilet cover 6, when toilet cover 6 is opened and closed, the end of toilet cover 6 is not subjected to the obstruction of unit box 30, thus can adopt the toilet cover of not offering breach 6 with straight line shape end, thereby can improve the appearance design intention of Western water closet 1.
In addition, taking turns 73 with the 4th is that final gear, idler gear 8, actuation gear 50 and connecting wheel 40 are when being placed in width dimensions with narrow space that damping case 220 outside dimensions equate substantially, if without reasonable arrangement, then the height of unit box 30 can increase, but because in this form, as described below, with the longitudinally compact setting of each constituent part, so,, also can be compressed its height dimension even adopt unit box 30 with standing portion 10a.
That is, as shown in Figure 6, toilet cover has with the damping case 220 of oil damping device 22 protuberance 221 that stretches out is downwards arranged, and 221 pairs of opposition side ends that are meshed with the actuation gear 50 of the turn central shaft 9 of idler gear 8 of this protuberance are supported.In addition, the 4th take turns 73 be final gear have with the small gear 731 of idler gear 8 engagement and be positioned at its underpart with the 3rd to take turns 72 be the gearwheel 732 of leading portion gear engagement, this gearwheel 732 is observed its top and protuberance 221 overlaids from the axial direction of rotatingshaft 20.Because these overlay structure characteristics, this form can be provided with each constituent part is longitudinally compact, thus the height dimension of compression unit case 30.
And, the idler gear 8 that adopts in this form, the size of its axial direction is longer than the size of toilet cover with the axial direction of oil damping device 22, a side end of idler gear 8 and actuation gear 50 engagements, it is final gear engagement that end side and the 4th takes turns 73.Thereby, can easily constitute to make and be meshed with a side end of idler gear 8 with the actuation gear 50 of oil damping device 22 more close rotatingshaft 20 shaft end side and with the structure that supports with the end of opposition sides actuation gear 50 engagements turn central shaft 9 of 221 pairs of idler gears 8 of protuberance of damping case 220 than toilet cover.
In addition, in this form, taken in toilet seat in the unit box 30 with oil damping device 21, the damping case of this oil damping device 21 is made of the part 210 of unit box 30.Thereby, although toilet seat fulcrum 11 is thicker than rotatingshaft 20, owing to can omit the damping case that constitutes by other independent part, so toilet seat also can be accommodated in oil damping device 21 in the standing portion 10a of narrow width of unit box 30.
(on-off action of toilet cover)
In the toilet cover opening _ closing unit 10 of this form, when toilet cover 6 was in fully open position P0, shown in Fig. 5 (A), the side margin 521 that the side margin 511 that the projection 41 of connecting wheel 40 is positioned at the groove 51 that is arranged on the actuation gear 50 reaches circular-arc recess 52 nearby nearby.
Under this state, detect that nobody uses on the toilet seat unit 4, and be statically placed in opening state when having passed through scheduled time when the full cut-off sensor 97 of toilet cover opening _ closing unit 10 detects toilet cover 6, stepping motor 60 at first drives the number of steps of regulation to postive direction.As a result, the rotation of the output shaft of stepping motor 60 to the 1st take turns the 70, the 2nd take turns the 71, the 3rd take turns the 72, the 4th take turns 73, idler gear 8 and actuation gear 50 transmit, shown in Fig. 5 (B), actuation gear 50 rotates 60 ° to counterclockwise CCW direction.This position is the final position of actuation gear 50.So carrying out in the rotating process, the projection 41 that is positioned at the connecting wheel 40 of the groove 51 of actuation gear 50 and circular-arc recess 52 is subjected to pushing of edge 511,521 separately, so make connecting wheel 40 rotate 60 °, toilet cover 6 is toppled over initial position P4 by self-support holding position P1 and deadweight and is arrived backward position P5.Therebetween, when toilet cover 6 before fully open position P0 arrives at pulsation rate switching position P2 by self-support holding position P1, the pulsation rate that puts on stepping motor 60 is controlled at the A level and produces large driving force, and after toilet cover 6 is by pulsation rate switching position P2 during arriving at backward position P5, the pulsation rate that puts on stepping motor 60 is increased to the B level, and rotational velocity is enhanced.
So to toilet cover 6 when closing direction drives, after toilet cover 6 is toppled over initial position P4 by deadweight, rely on deadweight to continue to topple over, after backward position P5 stopped motoring, toilet cover 6 also can be swung to full close position P7.At this moment, owing to be provided with oil damping device 22 at rotatingshaft 20, so toilet cover 6 can sharply not toppled over.In addition, owing to be provided with oil damping device 21 at toilet seat fulcrum 11, so toilet seat 5 can sharply not toppled over.
When toilet cover 6 so relied on deadweight to swing to full close position P7, the projection 41 of connecting wheel 40 shown in Fig. 5 (C), was rotated 60 ° to counterclockwise CCW direction.But owing to leave sufficient play between the groove 51 of actuation gear 50 and circular-arc recess 52 and the projection 41, thereby actuation gear 50 does not interfere with each other with projection 41, among actuation gear 50 and the connecting wheel 40, has only connecting wheel 40 and toilet cover 6 interlocks.
In addition, when toilet cover 6 by when the closing direction rotation drives, because being fixed in the sensor of connecting wheel 40 rotates along counterclockwise CCW direction with magnet 96, so when toilet cover 6 closes on full close position P7 and is positioned at 30 ° of angular orientations (full cut-off detection position P6), sensor is approaching with magnet 96 and position transducer 97, and the output signal that position transducer 97 sends is switched.Thus, the signal by from position transducer 97 outputs can be detected closing of toilet cover 6.
On the other hand, in the moment of toilet cover 6 by backward position P5, stepping motor 60 counterrotatings, actuation gear 50 rotates 60 ° to clockwise CW direction, returns the primary position shown in Fig. 5 (C).At this moment, actuation gear 50 does not return primary position with projection 41 with interfering with each other.
When moving to full close position P7 as described above, toilet cover 6 is in action during finishing stage, if there is the user to open toilet cover 6 with manual mode, then connecting wheel 40 is moving with being rotatedly connected of toilet cover 6, be back to position shown in Fig. 5 (A) by position shown in Fig. 5 (C), and this moment actuation gear 50 owing to be back to primary position, therefore, projection 41 not with actuation gear 50 interferences.Thus, light and handy power need only be applied and just toilet cover 6 fully open position P0 can be back to.
(action of the occasion that toilet cover is opened in closing the driving process and effect thereof)
Meet this situation, stepping motor 60 should leave toilet cover 6 and arrive at number of steps before the backward position P5, but since this form with it cancellation,, the driving to closing direction of toilet cover 6 is stopped so stepping motor 60 is had no progeny in by external force.
In addition, toilet cover 6 by motor in the driven process of closing direction, be returned the situation of fully open position P0 if when it's convenient cover 6 because of artificial external force, because actuation gear 50 therefore external force has been back to the position shown in Fig. 5 (A), thereby stepping motor 60 no longer carries out the backward rotation that should carry out after toilet cover arrives at backward position P5.
As mentioned above, the toilet cover opening _ closing unit 10 of this form, toilet cover 6 by motor in the process that closing direction drives, toilet cover by by detect by sensor 98 pass through detection position P3 (pulsation rate switching position P2) after, if run into toilet cover 6 is returned fully open position P0 by artificial external force operation situation, stepping motor 60 is had no progeny in by external force, and the driving to closing direction of toilet cover 6 is stopped.Thus, avoided in use taking place the inconvenience that toilet cover 6 falls down.
In addition, toilet cover 6 by motor in the process that closing direction drives, when running into toilet cover 6 and being returned the situation of fully open position P0 by artificial external force operation, stepping motor 60 no longer carries out the backward rotation that should carry out after toilet cover arrives at backward position P5.Therefore, can not take place because of unnecessary initial stage action causes the projection 55 of actuation gear 50 and the situation of restraint part 31 collisions, thus can not send abnormal noise, and can prevent to sustain damage because of collision causes projection 55 or restraint part 31.
Further, in this form, for guaranteeing that toilet cover 6 can be reliably by self-support holding position P1 from fully open position P0, drive stepping motor 60 with pulsation rate A, and when toilet cover 6 by behind the pulsation rate switching position P2, then the pulsation rate B of excess torque drives stepping motor 60 after the deduction self-support holding torque producing.Thus, as in toilet cover 6 closing motion processes, when hope is back to opening state with hand with it, if toilet cover 6 has roughly passed through self-support holding position P1 (pulsation rate switching position P2), just then can open it with light and handy power.In addition, as with little drive force toilet cover 6, can therefore improve the rotating speed of stepping motor 60, thereby can make toilet cover 6 turn to closed condition rapidly.Thus, when the next bit user comes then, toilet cover 6 can not become the peculiar scene to the closing direction activity.
[example 2]
Above-mentioned form 1, though be constituted as, when toilet cover 6 is driven in the process to closing direction by motor, return fully open position P0 with detecting by artificial external force by sensor 98, thereby stopping to interrupt of the driving of 60 pairs of toilet covers 6 of later stepping motor to closing direction, yet, also can not use by sensor 98, only rely on the driving force of stepping motor 60, can prevent that just the accident of toilet cover 6 from toppling over.
Be specifically described as follows: above explain according to Fig. 4, toilet cover 6 is before fully open position P0 arrives at pulsation rate switching position P2 by self-support holding position P1, the pulsation rate that puts on stepping motor 60 is controlled at low-level (pulsation rate A), to produce big driving force, and after toilet cover 6 is by pulsation rate switching position P2 until the stage of arriving at backward position P5, the pulsation rate that then will put on stepping motor 60 is increased to high level (pulsation rate B), though this moment, driving force was little, had improved rotating speed.And, the driving force level of the stepping motor 60 that after toilet cover 6 is by pulsation rate switching position P2, is produced with pulsation rate B, deficiency so that toilet cover 6 by self-support holding position P1.
Thus, when toilet cover 6 to closing direction by the motoring process in, when toilet cover 6 is returned fully open position P0 with toilet seat 5 by artificial external force, even carry out the driving of closing direction by 60 pairs of toilet covers of stepping motor 6 once more after being interrupted, the driving force that stepping motor 60 is produced with pulsation rate B can't make toilet cover 6 and toilet seat 5 by self-support holding position P1.Therefore, in closing direction driving process,, can not produce the inconvenience that toilet cover 6 and toilet seat 5 fall down even toilet cover 6 and toilet seat 5 are turned back to fully open position P0 by artificial external force yet.
[other examples]
In the above-mentioned form, adopted from the observation of rotatingshaft 20 axial directions to be the unit box 30 of L font,, also can adopt the unit box 30 of I font as shown in Figure 7 as long as have the standing portion 10a that leaves the space in the side.Because the formation when adopting this element case 30 is identical with above-mentioned example, so adopt same numbering to invest among the figure to part with identical function, and omit explanation.In addition, as long as have the standing portion 10a that leaves the space in the side, also can adopt the unit box 30 of inverted T-shape.
In addition, in the above-mentioned form, the increase and decrease of stepping motor 60 driving forces is realized by switching pulsation rate, also can merely realize by the voltage or the electric current that change motor.
