The specific embodiment
At first, preferred embodiment describe of the present invention.
As long as the lowest water level in the wc flushing cistern and the storage water yield between the sensed water level are set as more than the water retention capacity of flushing toilet.
According to such structure, can in for the second time flushing, make the amount corresponding with retaining in the lavatory pan be replaced as new flushing water.Therefore, even produced cleaning and removing residual in the first time behind the flushing operation, also can eliminate effectively cleaning and removing residual in the flushing for the second time.
In addition, also can be in the following way, that is, flushing toilet belongs to siphon toilet, and possesses " the backwater feed path " that is communicated in the siphon toilet in the flushing water supply unit.
According to such structure, although in for the second time flushing, when supplying water in from the flushing water supply unit to lavatory pan, the part of output can be discharged under the effect of the siphon of closet,, the water level that might cause closet do not reach the situation of common water retention capacity thereby being lower than flood level, but owing to from the backwater feed path supply amount corresponding with this deficiency separately, therefore can guarantee the water retention capacity that lavatory pan is interior.
And, also can be in the following way, namely, flushing toilet is siphon toilet, the sensed water level of level sensor is set to, and has added at least the amount corresponding with the backwater in the siphon toilet and the water level that reaches, simultaneously, the near water yield that is equivalent to less the amount of backwater of flushing water supply unit is supplied with in siphon toilet with the state that can not produce siphonage.
According to this mode, when washing for the second time, can guarantee to have at least in the wc flushing cistern in common water retention capacity having added the amount of backwater and the water yield that obtains.And when washing for the second time, the flushing water supply unit can supply water to siphon toilet with larger flow at first.Although the water yield of supplying with during this period can owing to the siphonage part that runs off, afterwards, will be supplied to can not produce the state of siphonage the water yield of the amount that is equivalent to less backwater.In this way, can guarantee the predetermined water retention capacity that closet is interior.
Fig. 1 and Fig. 2 illustrate embodiments of the invention 1.Flushing toilet among the embodiment 1 has toilet body 1.Bottom at the urinal 2 of toilet body 1 is formed with water seal section 3.Above water seal section 3, drainage channel 4 one distolateral towards urinal 2 the bottom surface and opening downwards.Drainage channel 4 is formed, and after rising obliquely upward from urinal 2 interior openends, hangs down vertically.Another of drainage channel 4 be distolateral to be connected to not shown gutter.
Be used for storing in advance the wc flushing cistern 5 of the flushing water that should supply with to toilet body 1, with toilet body 1 in abutting connection with and arrange.Wc flushing cistern 5 is joined together by pipe arrangement 6 with toilet body 1.Opening is located, another distolateral top that is connected in the toilet body 1 in one distolateral bottom at wc flushing cistern 5 of pipe arrangement 6.Pipe arrangement 6 pump 7 is installed midway so that can be by by the operated flush switch 8 of closet user, and with the flushing waters in the wc flushing cistern 5 to toilet body 1 force feed and supply with.9 controls of pump 7 controlled devices, and as described later, the actuation time of the pump 7 when in control device 9, being set with once flushing.Thus, pump 7 constitutes, and controls by control device 9, and as described later, has set the actuation time of the pump 7 in once cleaning in control device 9.In addition, consisted of flushing water supply unit S of the present invention by pump 7, pipe arrangement 6 and control device 9.
On the other hand, one of the T of the cistern water supply section distolateral top that is configured in the wc flushing cistern 5.The T of cistern water supply section has the pipe arrangement 10 that is connected with running water pipe, and an end of pipe arrangement 10 is located opening above wc flushing cistern 5.At pipe arrangement 10 feed water valve 11 is installed.This feed water valve 11 is the electromagnetic type open and close valve, and is constituted as, and makes to wc flushing cistern 5 by control device 9 and supplies water or the action that stops is controlled.
Be provided with for the level sensor 12 that the water level that sets is detected in the inside of wc flushing cistern 5.Level sensor 12 is made of the pillar 13 on the bottom surface that uprightly is arranged on wc flushing cistern 5 and the test section 14 that is installed on the upper end of this pillar 13.In pillar 13, take in the lead-in wire (not shown) that is connected with test section 14.Lead-in wire is led to the outside from the bottom surface of wc flushing cistern 5, and is connected with control device 9.
The water level that is detected by level sensor 12 (water level that represents with H3 among Fig. 2 (C): below, be called sensed water level) be, lowest water level (the water level shown in the H1 among Fig. 2 (A), compare with the opening of pipe arrangement 6 and to be arranged in the top) and peak level (water level shown in the H2 of this figure) between water level, its expression, from lowest water level H1 to the wc flushing cistern 5 interior water yields of storing the sensed water level H3, with urinal 2 interior water retention capacitys of the storing (water yield of retaining when having reached flood level H4 urinal 2: Q) compare identical or slightly many water level.
In addition, although not shown, in wc flushing cistern 5, also be provided with for the water level detecting unit that peak level H2 is detected (for example optical pickocff).Thereby constitute, control device 9 is based on the situation of water level detecting unit inspection to high water level H2, and to supply-water pump 11 output out codes.
In addition, control device 9 is set to, in situation about not being transfused to from the detection signal of level sensor 12, even flush switch 8 is operated, do not allow the driving of pump 7 yet, and when being transfused to the detection signal that has from level sensor 12, allow the driving of pump 7.In addition, in the situation of present embodiment, in control device 9, be set with the actuation time of two kinds of pumps 7.
That is, in control device 9, in the situation that flush switch 8 has been operated when detecting peak level H2 by not shown water level detecting unit, select the T1 time with as actuation time.The T1 time is, sprays time of the following water yield by pump 7, and the described water yield is, the water level in the wc flushing cistern 5 drops to the water yield in the interval till the lowest water level H1 from peak level H2.This interval water yield is fully more than the water retention capacity of toilet body 1.On the other hand, in the situation that flush switch 8 has been operated when not detecting peak level H2 having detected sensed water level H3, then control device 9 is selected T2 times (T1＞T2) with the actuation time as pump 7.The T2 time for the time of ejection water yield Q ', described water yield Q ' is, with water retention capacity Q in the urinal 2 about equally or slightly more than the water yield of the water retention capacity Q in the urinal 2.
Action effect to the embodiment 1 that consists of in the above described manner describes.When being in wc flushing cistern 5 under the state of peak level H2, when behind defecation not shown flush switch 8 being operated, control device 9 will select the T1 time that pump 7 is driven.Make flushing waters in the wc flushing cistern 5 by pipe arrangement 6 and once to toilet body 1 interior ejection by pump 7.Flushing water will be by the effect of siphon flows out to drainage channel 4 with floating pollutant from the water seal section 3 of urinal 2 strong, and discharges to the discharge pipe of outside.And if passed through T1 actuation time that sets, then control device 9 will make pump 7 stop, and flow in the toilet body 1 thereby stop flushing water.
This result who washes for the first time is that the water level in the wc flushing cistern 5 becomes the state of lowest water level H1(Fig. 2 (A)).Therefore, in during this to the water yield of toilet body 1 interior ejection be, fully more than the water yield of the water retention capacity of urinal 2.When the driving of pump 7 is stopped, owing to the 11 output valve opening signals from control device 9 to feed water valve, thereby will supply with flushing waters to wc flushing cistern 5 by pipe arrangement 10.
As mentioned above, even after having implemented primary flushing, sometimes also can produce cleaning and removing residual in the urinal 2.Under these circumstances, be envisioned that the user in can be after for the first time flushing very short time wish attempt washing for the second time.But, shown in Fig. 2 (B), even when being in the process of supply flushing water in the wc flushing cistern 5, and water level is not when returning to sensed water level H3, level sensor 12 can be to control device 9 output detection signals.At this moment, because in control device 9, still incomplete to the condition that pump 7 drives, even therefore flush switch 8 is operated pump 7 is driven.Therefore, just do not begin to carry out for the second time situation of flushing during can not occurring in that water levels in the wc flushing cistern 5 fully do not recover.
When the water level in the wc flushing cistern 5 shown in Fig. 2 (C), when having reached sensed water level H3, after this, control device 9 will be by the input from the detection signal of level sensor 12, and becomes the state of the driving that allows pump 7.Therefore, when operation flush switch 8 after sensed water level is detected, control device 9 will select the T2 time that pump 7 is driven, thereby begin to carry out the flushing second time.And when having passed through T2 during the time, the action of pump 7 will stop, and the water retention capacity Q that is ejected to the water yield in the toilet body 1 and urinal 2 during this period is about equally or slightly more than the water retention capacity Q of urinal 2.On the other hand, owing in wc flushing cistern 5, be set to the water yield the lowest water level H1 from sensed water level H3, with water yield Q about equally or slightly more than water yield Q, even therefore after flushing finishes for the second time, the water levels in the wc flushing cistern 5 can not be lower than lowest water level yet.In this way, the water yield to toilet body 1 ejection when washing for the second time is, and is identical with the water retention capacity Q of urinal 2 or slightly more than the amount of the water retention capacity Q of urinal 2.Therefore, in for the second time flushing, the amount corresponding with retaining in the urinal 2 almost all can be replaced as new flushing water, therefore, even producing cleaning and removing residual in the flushing for the first time, also can eliminate cleaning and removing residual by for the second time flushing.
Fig. 3 illustrates embodiments of the invention 2.The difference of present embodiment and embodiment 1 is, is provided with the backwater feed path 15 that is communicated in the toilet body 1 at flushing water supply unit S.Backwater feed path 15 one distolateral with at the downstream portion place of feed water valve 11 is connected from the mode of the pipe arrangement top set of extending towards wc flushing cistern 5.Distolateral place, the top opening in toilet body 1 of another of backwater feed path 15.In this embodiment, backwater feed path 15 be provided with choke valve 16 midway so that the flow in the backwater feed path 15 becomes, can not make the flow on the degree of toilet body 1 interior generation siphonage.
According to the embodiment 2 that consists of in the above described manner, when in similarly to Example 1 mode and when having finished primary flushing, make feed water valve 11 drive valve by control device 9, thereby to wc flushing cistern 5 interior supply flushing waters, simultaneously, flushing water is not flow in the toilet body 1 from backwater feed path 15 by the state of throttling with its flow.
, by pump 7 and strong during the toilet body 1 interior ejection flushing water, in drainage channel 4, can produce siphonage.Therefore, although be set as, the water yield that sprays in the T1 in the actuation time of pump 7 is greater than the water retention capacity Q in the urinal 2, if supply with flushing waters from backwater feed path 15, then also can make the water level in the urinal 2 be lower than flood level H4, thereby produce the situation that to guarantee water retention capacity.
But, in the present embodiment, owing to adopted following mode, that is, after pump 7 has stopped, with the flow on the degree that can not produce siphonage, carry out the supply of flushing water from backwater feed path 15 to toilet body in 1, therefore in urinal 2, guaranteed water retention capacity Q.
Other structure is identical with embodiment 1, and can bring into play same action effect.
Fig. 4 illustrates embodiments of the invention 3.In the present embodiment, the sensed water level H5 of wc flushing cistern 5 is different from other embodiment.In embodiment 1, the water yield between sensed water level H3 and the lowest water level H1 is set to, with the water retention capacity (Q) of toilet body about equally or slightly more than the water yield (Q ') of the water retention capacity (Q) of toilet body, and in the present embodiment, so that this water yield becomes, the water yield that has added on its basis the amount corresponding with backwater (Q1) and obtained (Q '+Q1) mode, set sensed water level and improve.
In addition, in the present embodiment, in the toilet body 1 the ejection flushing water during, the operation mode of pump 7 is switched to the little operation mode of ability by the large operational mode of ability.
To produce siphonage in the drainage channel 4 in toilet body 1 at the flushing water of supplying with under the large operation mode of ability, and can not produce siphonage in that the little operational mode of ability is next.
In control device 9, flush switch 8 is being carried out during to peak level H2 by not shown water level detecting unit inspection in the situation of operation, will select the T3 time with the duration as the large operation mode of ability.The T3 time is, sprays time of the following water yield by pump 7, and the described water yield is, water level in the wc flushing cistern 5 is reduced to from peak level H2 compares with lowest water level H1 and improved the water yield in the interval till the water level with the corresponding amount of backwater.In addition, control device 9 is set to, and when having passed through T3 during the time, the operation mode that the ability that switches to is little also continues the T4 time.
On the other hand, when detecting sensed water level H5 but not detecting peak level H2 flush switch 8 has been carried out in the situation of operation, control device 9 will be selected T2 time (T3＞T2) with the actuation time as pump 7.The T2 time is, pump 7 sprays the time of water yield Q ' under the large operation mode of ability, and described water yield Q ' is, with water retention capacity Q in the urinal 2 about equally or slightly more than the water yield of the water retention capacity Q in the urinal 2.Control device 9 is set to, and when having passed through T2 during the time, operation mode is switched to the little operation mode of ability and continues the T4 time.
According to the embodiment 3 that consists of in the above described manner, if when being in peak level H2 in flushing cisterns 5 flush switch 8 is operated, then pump 7 at first drives the T3 time with the large operation mode of ability.During this period, because pump 7 is with larger flow ejection flushing water, thereby by siphonage the dirts in the water seal section 3 when being attracted, drainage channel are discharged from.Water level in the wc flushing cistern 5 at the time point place of having passed through the T3 time becomes, from lowest water level, improved after the water yield Q1 water level, wherein, water yield Q1 is equivalent to the amount corresponding with backwater.
Passing through T3 after the time, control device 9 switches to the little operation mode of ability with the operation mode of pump 7.After this, pump 7 is with smaller flow ejection flushing water.And although passing through T4 after the time, the water yield Q1 that is equivalent to the amount of backwater is ejected in the toilet body 1, owing to can not produce siphonage during this period, so the water level in the urinal 2 will reach flood level.
On the other hand, in for the second time flushing, when having detected sensed water level H5 at level sensor 12 but do not detect under the state of peak level H2 when flush switch 8 operated, control device 9 will be selected the T2 time, and (T3＞T2) is as the driving time of pump 7.During this period, pump 7 sprays water yield Q ' with larger flow, and described water yield Q ' is, with the retaining flow about equally or slightly more than the water yield of retaining flow.Although produced during this period siphonage, after the time, because pump 7 is switched to the little operation mode of ability, so siphonage will temporarily be interrupted through T2.Therefore, as long as sprayed the water yield Q1 that is equivalent to the amount corresponding with backwater in during the T2 time in urinal 2, the water level in the urinal 2 just can reach flood level.In a word, even after having implemented for the second time flushing, also can in urinal 2, guarantee the water retention capacity Q that is scheduled to.
Other structure is identical with other embodiment, and can bring into play same action effect.
Fig. 5 illustrates embodiments of the invention 4.Adopted in the present embodiment following structure, that is, wc flushing cistern 17 has been arranged on the position of comparing top side with toilet body 1, and from the structural element of flush water supply device S, has removed pump.
Particularly, in the upper shed of the bottom surface of wc flushing cistern 17 limbers 18 is arranged, and be communicated in the toilet body 1 via not shown pipe arrangement.This limbers 18 can open and close by flushing valve 19, and flushing valve 19 is connected with rotatable washed handle 20 by spherical chain 21.Be connected with motor 22 at washed handle 20, and motor 22 is by based on the operation of flush switch 8 and from the driving instruction of control device 9 outputs, thus driven.
In addition, 23 is bleed off pipe.
The present invention can also be applied in the lavatory pan such as this form of supplying with to toilet body 1 by action of gravitation and with the flushing water in the wc flushing cistern 17 of embodiment 4.Embodiment 4 can also add the structure of the backwater feed path 15 as embodiment 2, perhaps with embodiment 3 such, the sensed water level of wc flushing cistern 5 add with the textural association of the corresponding amount of backwater together.
Other structure is identical with the structure of embodiment 1 to embodiment 3, and can bring into play the action effect identical with these embodiment.
