Description

Chamber pot flushing water method for supplementing water

Technical field

The present invention relates to a kind of closet, particularly a kind of bath method for supplementing water of closet.

Background technology

Closet is as a kind of blowdown apparatus, and usually utilize siphonic effect to be kinetic energy by liquid potential energy converting and energy, liquid is swept along, and dirt enters in sewer pipe, completes blowdown process.

For novel intelligent closet, usually there are two kinds to the method for supplementing water of closet:

Method a: newly open an intake tunnel on closet, carries out moisturizing with the bypass of water intaking valve itself, the precision gist valve body precision of rate of water make-up.This method for supplementing water, due to the newly-increased moisturizing passage of needs, cause closet to design complicated, moisturizing low precision, and in airtight water tank, this method easily causes pollution of waterhead.

Method b: after dirt discharges closet, uses water pump to be continued to flow to basin body by the water in water tank.After dirt discharge, water seal disappears, and closet and sewer pipe will be connected state.Now, the foul smell in building pipe or small worm can diffuse to room.Therefore, in order to ensure dwelling environment, need moisturizing as early as possible.The all baths of indirect request all need to store in advance in water tank, thus cause water tank volume to increase.

Summary of the invention

The object of the present invention is to provide a kind of chamber pot flushing water method for supplementing water.Utilize the method, both avoided the toilet bowl structure complexity that newly-increased moisturizing passage causes, reduced again water tank volume, and decrease the space hold of closet entirety.

To achieve these goals, the present invention devises a kind of chamber pot flushing water method for supplementing water, comprises following steps:

After water tank receives flush signal, wash by water in closet, closet blowdown;

After being flushed, described water tank carries out first time moisturizing to described closet, and after first time moisturizing, closet water level rises, and the height of water level after rising is not less than h ₁, h ₁for the closet water surface forms the critical groundwater table height required for water seal;

After first time, moisturizing terminated, water tank carries out second time moisturizing to closet.

For Intelligent closestool of the prior art, embodiments of the present invention are passed through separated for the step of water tank to chamber pot flushing water, first time moisturizing, second time moisturizing, make only to need to store the water yield met needed for single step in water tank at every turn, can reach and use water requirement.Therefore, water tank is completely washed by water and the whole water yields needed for moisturizing without the need to disposable storage, reduces the volume requirements to water tank.

As preferably, after bath in closet, before first time moisturizing is carried out to closet, also comprise following steps:

Judge whether supplying water condition is reached for the first time;

If judge, supplying water condition is reached for the first time, then described water tank carries out first time moisturizing to described closet, otherwise repeats described judgement, until judge that supplying water condition is reached for the first time.

Add the determining step that first time supplying water condition is carried out, moisturizing can be carried out on suitable opportunity to closet, thus make the water level in closet return back to water seal position more in time.

As preferably, this first time supplying water condition be: when closet water level is lower than design initial water level.That is, when closet blowdown, closet water level is once decline, and start first time moisturizing immediately, by the raise of stage in closet, and the height of water level after lifting is not less than h ₁.Thus, can within the shortest time, make the water level of closet reach water seal position, and then effectively prevent the gas dispersion in sewer pipe to indoor.Now, as long as the volume of water tank storage bath and the total Water for the first time needed for moisturizing, therefore in terms of existing technologies, water tank can have less volume, and the space taken is less.

As preferably, this first time supplying water condition also can be: water volume in water tank reaches V ₁and V ₁meet:

$V_{max}\≥V_1\≥V_a-\frac{V_a}{V_{mus}}\×V_{add};$

In formula, V _maxfor the initial water yield of water tank, V _afor closet water level rises to h from the height of water level after closet blowdown ₁the required water yield, V _musfor unit time water tank is to the rate of water make-up of closet, V _addfor unit time external water source is to the rate of water make-up of water tank, V _add<V _mus.For front a kind of preferred version, only can store the water yield needed for bath in water tank, thus further reduce the volume of water tank.

Due to V ₁magnitude relationship to the first time supplementary water time of water tank to closet.And work as V ₁more hour, water tank is moisturizing more early, and the hazardous substances in sewer pipe spreads also fewer towards indoor, therefore further, as preferably, and V ₁meet:

$V_a\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}.$

At water tank closet carried out in the step of first time moisturizing, as preferably, following sub-step can also be comprised:

Judge whether the closet water surface forms water seal by the first sensor be located in closet;

If judge, the closet water surface forms water seal, then terminate first time moisturizing; If judge, the closet water surface does not form water seal, then water tank continues described closet moisturizing, until first sensor judges that the closet water surface forms water seal.

By this sub-step, can guarantee that in water tank, the closet water surface can form water seal, eliminate error of calculation, and then prevent that water seal is not in place causes the gas in sewer pipe to spread for a long time.Further, can guarantee when water level after closet blowdown is lower than initial designs water level but higher than critical groundwater table height h ₁time, moisturizing stage first time directly terminates, and then prevents excessive moisturizing.

In addition, as preferably, after first time moisturizing is carried out to closet, before second time moisturizing is carried out to closet, can also following steps be comprised:

Judge whether second time supplying water condition is reached;

If judge, second time supplying water condition is reached, then water tank carries out second time moisturizing to closet, otherwise repeats described judgement, until judge that second time supplying water condition is reached.

Add the determining step that second time supplying water condition is carried out, moisturizing can be carried out on suitable opportunity to closet, thus make the water level in closet return back to initial water level more accurately.

As preferably: second time supplying water condition is: water volume in water tank reaches V ₂and V ₂meet:

$V_{max}\&GreaterEqual;V_2\&GreaterEqual;V_b-\frac{V_b}{V_{mus}}\&times;V_{add};$

In formula, V _maxfor the initial water yield of water tank, V _bfor closet water level is from h ₁rise to the water yield needed for design initial water level of closet, V _musfor unit time water tank is to the rate of water make-up of closet, V _addfor unit time external water source is to the rate of water make-up of water tank, V _add<V _mus.Same, V ₂magnitude relationship to the second time supplementary water time of water tank to closet.And work as V ₂more hour, water tank is moisturizing more early, and the water level of closet more early returns to initial water level.

Carry out, in the step of second time moisturizing, also comprising following sub-step to closet at water tank:

Judge whether the closet water surface reaches design initial water level by the second sensor be located in closet;

If judge, the closet water surface reaches design initial water level, then terminate second time moisturizing; If judge, the closet water surface does not reach design initial water level, then water tank continues closet moisturizing, until the second sensor judges that the closet water surface reaches design initial water level.

By this sub-step, can guarantee that in water tank, the closet water surface can get back to design initial water level, eliminate error of calculation, and then prevent water level not in place and affect the flush cycle of next round.Further, can guarantee when water level after closet moisturizing is higher than initial designs water level, the second time moisturizing stage directly terminates, and then prevents excessive moisturizing.

In addition, as preferably, in the process of above-mentioned bath, first time moisturizing, second time moisturizing, can by the water level monitoring water volume in water tank of monitoring water tank, also can be washed by water by monitoring or moisturizing complete after through time supervision water volume in water tank.Wherein, the water yield being carried out monitoring water tank by monitoring water tank water level only need arrange water level monitor in water tank, and it arranges comparatively simple, with low cost.After being completed by monitoring bath or moisturizing through time supervision water volume in water tank then lower to the requirement of water tank internal environment comparatively speaking, when being in water tank on the vehicles acutely rocked still can exactly the water yield of water tank.

In addition, as preferably, in the process of bath, first time moisturizing, second time moisturizing and after first time, second time moisturizing complete, also comprise following steps: whenever water volume in water tank is lower than V _maxtime, external water source carries out moisturizing to water tank, until water volume in water tank reaches V again _max, V _maxfor the initial water yield of water tank.

Immediately moisturizing is carried out to water tank when water volume in water tank starts to decline, then can ensure within the shortest time, the water in water tank to be filled, thus the moisturizing efficiency of water tank to closet is also improved, the water level of closet is restored within the shortest time.

Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.

First embodiment of the present invention relates to a kind of chamber pot flushing water method for supplementing water, shown in Fig. 1 and Fig. 2, comprises following steps:

Step S101, after water tank 2 receives flush signal, washes by water, realizes the dirt eliminating function of closet 1 in closet 1.This step is same as the prior art, does not repeat them here.

Step S102, judges whether supplying water condition is reached for the first time; If judge, supplying water condition is reached for the first time, then enter step S103, water tank 2 pairs of closets 1 carry out first time moisturizing, otherwise repeats to judge, until judge that supplying water condition is reached for the first time.

In the step S102 of present embodiment, this first time supplying water condition be: when closet 1 water level is lower than design initial water level.That is, when closet 1 blowdown, closet 1 water level is once decline, and start first time moisturizing (as being driven in closet by the water of water pump by low water stage) immediately, by the raise of stage in closet, and the height of water level after lifting is not less than h ₁.Thus, can within the shortest time, make the water level of closet 1 reach water seal position, and then effectively prevent the gas dispersion in sewer pipe to indoor.

Therefore, in the present embodiment, as long as water tank 2 stores the volume of bath and the total Water for the first time needed for moisturizing, therefore in terms of existing technologies, water tank 2 can have less volume, and the space taken is less.

In the present embodiment, by adding the determining step carried out first time supplying water condition, moisturizing can be carried out on suitable opportunity to closet 1, thus making the water level in closet 1 return back to water seal position more in time.

Step S103, after being flushed, water tank 2 pairs of closets 1 carry out first time moisturizing, and after first time moisturizing, closet 1 water level rises, and the height of water level after rising is not less than h ₁, h ₁for closet 1 water surface forms the critical groundwater table height required for water seal;

Step S104, judges whether second time supplying water condition is reached; If judge, second time supplying water condition is reached, then water tank 2 pairs of closets 1 carry out second time moisturizing, otherwise repeat described judgement, until judge that second time supplying water condition is reached.

In the step S104 of present embodiment, second time supplying water condition is: water tank 2 water yield rises to the initial water yield of water tank 2.When water tank 2 water yield gets back to the initial water yield of water tank 2, water tank 2 has abundant water to carry out supplementary closet 1.In this programme, water tank 2 water yield rises to the condition of the initial water yield and overlaps to the condition of water tank 2 moisturizing, detection scheme can be merged, thus the manufacturing cost of water tank 2 is declined.

Add the determining step that second time supplying water condition is carried out, moisturizing can be carried out on suitable opportunity to closet 1, thus make the water level in closet 1 return back to initial water level more accurately.

Step S105, after second time supplying water condition is set up, water tank 2 pairs of closets 1 carry out second time moisturizing.

In addition, it will be understood by those skilled in the art that in the process of bath, first time moisturizing, second time moisturizing and first time, second time is after moisturizing completes, whenever water tank 2 water yield is lower than V _maxtime, external water source can carry out moisturizing to water tank 2 at once, until water tank 2 water yield reaches V again _max, V _maxfor the initial water yield of water tank 2.Immediately moisturizing is carried out to water tank 2 when water tank 2 water yield starts to decline, then can ensure within the shortest time, the water in water tank 2 to be filled, thus the moisturizing efficiency of water tank 2 pairs of closets 1 is also improved, the water level of closet 1 is restored within the shortest time.However, it is also feasible for selecting carry out moisturizing to water tank 2 other opportunity, and this does not affect the realization of fundamental technics object of the present invention.

For Intelligent closestool of the prior art, present embodiment, by the watering step of water tank 2 pairs of closets 1 is divided into twice, makes water tank 2 completely wash by water and the whole water yields needed for moisturizing without the need to disposable storage, and then reduces the volume requirements to water tank 2.

Second embodiment of the present invention relates to a kind of chamber pot flushing water method for supplementing water, second embodiment is the further improvement of the first embodiment, main improvements are, in the second embodiment of the present invention: in step s 102, this first time supplying water condition be: water tank 2 water yield reaches V ₁and V ₁meet:

$V_{max}\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add};$

In formula, V _maxfor the initial water yield of water tank 2, V _afor closet 1 water level rises to h from the height of water level after closet 1 blowdown ₁the required water yield, V _musfor the rate of water make-up of unit time water tank 2 pairs of closets 1, V _addfor unit time external water source is to the rate of water make-up of water tank 2, V _add<V _mus.Wherein V _avalue can draw according to the concrete shape of closet 1.

It is evident that, in the present embodiment, V ₁magnitude relationship to the first time supplementary water time of water tank 2 pairs of closets 1.And work as V ₁more hour, water tank 2 more early moisturizing, the hazardous substances in sewer pipe spreads also fewer towards indoor, therefore, usually wish V ₁can be little as much as possible, thus water seal position can be formed in time.

Because water tank 2 is while closet 1 moisturizing, external water source is also to water tank 2 moisturizing, therefore, can by counting the water yield that moisturizing process peripheral water source fills in water tank 2, and moisturizing is completed, and the water yield that rear water box 2 fills into closet 1 is just in time more than or equal to V _a, make V ₁value less.

Accordingly, t can be established _mendfor the time spent by moisturizing process, V _mendfor external water source in this step of first time moisturizing at t _mendthe rate of water make-up of inner water tank 2 during this period of time, V _addfor unit time external water source is to the rate of water make-up of water tank 2, V _musfor the rate of water make-up of unit time water tank 2 pairs of closets 1, V _afor closet 1 water level rises to h from the height of water level after closet 1 blowdown ₁the required water yield, V ₁be the water capacity of the first moisturizing when starting in water tank 2, then can draw following three calculating formulas:

V ₁+ V _mend>=V _a;

V _mend=V _add× t _mend;

V _mma× t _mend=V _a;

Therefore, have:

$V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}.$

In formula, V _afor closet 1 water level rises to h from the height of water level after closet 1 blowdown ₁the required water yield, V _musfor the rate of water make-up of unit time water tank 2 pairs of closets 1, V _addfor unit time external water source is to the rate of water make-up of water tank 2, V _add<V _mus.

Obviously, to V ₁, its maximum value is V _max.Therefore can obtain:

$V_{max}\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}$

In addition, due to V _max>=V _aand in order to make V ₁little as much as possible, further, Ke Yiling:

$V_a\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}$

Due to pipeline restriction, in current most domestic environment, water source, unit interval inside and outside is all the rate of water make-up much smaller than unit interval inner water tank 2 pairs of closets 1 to the rate of water make-up of water tank 2 usually.That is, when the overwhelming majority, V _add<V _mus.Now, V is reached in water tank 2 water yield ₁afterwards first time moisturizing is carried out to closet 1, just can meet the water seal requirement of closet 1.For the first embodiment, in the present embodiment, only can store the water yield needed for bath in water tank 2, therefore present embodiment further reduces the volume of water tank 2.

And work as V _add>=V _mustime, because the water intake velocity of water tank 2 is greater than water speed, as long as therefore closet 1 water level decreasing is to h ₁just can carry out first time moisturizing afterwards, thus, the volume of water tank 2 also can miniaturization more.

3rd embodiment of the present invention relates to a kind of chamber pot flushing water method for supplementing water, 3rd embodiment is the further improvement of the second embodiment, main improvements are, in the 3rd embodiment of the present invention: in step S104, this second time supplying water condition is: water tank 2 water yield reaches V ₂and V ₂meet:

$V_{max}\&GreaterEqual;V_2\&GreaterEqual;V_b-\frac{V_b}{V_{mus}}\&times;V_{add};$

In formula, V _maxfor the initial water yield of water tank 2, V _bfor closet 1 water level is from h ₁rise to the water yield needed for design initial water level of closet 1, V _musfor the rate of water make-up of unit time water tank 2 pairs of closets 1, V _addfor unit time external water source is to the rate of water make-up of water tank 2, V _add<V _mus.

Same, V ₂magnitude relationship to the second time supplementary water time of water tank 2 pairs of closets 1.And work as V ₂more hour, water tank 2 more early moisturizing, the water level of closet 1 more early returns to initial water level.And work as V _add>=V _mustime, as long as closet 1 water level meets or exceeds h after rising ₁time, can second time moisturizing be carried out.

V ₂the computational methods that draw of optional interval and V ₁identical, therefore repeat no more in this article.But it is worth mentioning that, for second time moisturizing, the opportunity of moisturizing might not be the problem that override will be considered.Because first time moisturizing completes, closet 1 water level has reached water seal position h ₁, the dirt diffusion problem of sewer pipe is resolved, and therefore, the target of second time moisturizing is make closet 1 water level rise to the design initial water level of closet 1 and ready for wash by water next time, and the time urgency of this target is not strong.In addition, the water level susceptibility after second time moisturizing is not high yet, and that is, closet 1 water level after moisturizing floats to some extent and also can not impacts flush make a big impact near the design initial water level of closet 1.

But, make V ₂value as far as possible close still significant, this is because, work as V ₂close time, without the need to arranging the device detecting closet 1 water level in closet 1, and the water yield of second time moisturizing can be controlled by the form water in water tank 2 all being filled into closet 1, thus the manufacturing cost of closet 1 can be saved.

4th embodiment of the present invention relates to a kind of chamber pot flushing water method for supplementing water, 4th embodiment is the further improvement of the 3rd embodiment, main improvements are, in the 4th embodiment of the present invention: in the process of the bath described in step S101, S103, S105, first time moisturizing, second time moisturizing, can by water level monitoring water tank 2 water yield of monitoring water tank 2.

In the present embodiment, only with V ₁v is worked as example illustrates _add<V _mustime to V ₁water level monitoring:

Due to V ₁monitoring can by the height of water level j in monitoring water tank 2 ₁realize, suppose that C is the conversion coefficient between the water yield that can extract out of water tank 2 and water tank 2 water level, when water tank 2 water level is higher than j ₁time, condition is reached, therefore, and by:

C×V ₁＝j ₁；

$V_{max}\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}$

Can be derived from:

$V_{max}\&times;C>j_1\&GreaterEqual;(V_a-\frac{V_a}{V_{mus}}\&times;V_{add})\&times;C;$

In formula, C its depend on the structure of water tank 2, the water tank 2 for most shape and structure comparatively rule:

Due to:

$V_a\&times;C=\frac{V_a+V_x}{f},V_{max}\&times;C=\frac{V_{max}+V_x}{f};$

In formula, V _xfor water tank 2 content is positioned at the volume under the water surface, f is the floor space of described water tank 2.

Therefore, can draw:

$\frac{V_{max}+V_x}{f}>j_1\&GreaterEqual;\frac{V_a+V_x-\frac{V_a}{V_{mus}}\&times;V_{add}}{f};$

Specifically, the volume of water tank 2 content comprises and is not limited to: the volume shared under water when pump, pipeline and other component are located in water tank 2, water tank 2 inwall bossing relative to regular shape container shared by volume, suction pump cannot take out and water tank 2 bottom water shared by volume etc.Due to the volume taking into full account content, therefore present embodiment is more accurate to the calculating of water level, makes j ₁calculating more accurate.

For the water level j reached needed for second time replenishing water tank of water 2 ₂computational methods and j ₁roughly the same, therefore repeat no more in this article.

The water yield being carried out monitoring water tank 2 by monitoring water tank 2 water level only need arrange water level monitor in water tank 2, and it arranges comparatively simple, with low cost.

Obviously, in the present embodiment, also can by monitoring bath or moisturizing complete after through time supervision water tank 2 water yield.

Same, herein also only with V ₁v is worked as example illustrates _add<V _mustime to V ₁water level monitoring:

If t ₁the time waited for needed for first time moisturizing, by:

$t_1=\frac{V_1}{V_{add}};$

$V_{max}\&GreaterEqual;V_1\&GreaterEqual;V_a-\frac{V_a}{V_{mus}}\&times;V_{add}$

In formula, t ₁the time waited for needed for first time moisturizing.

Can draw:

$\frac{V_{max}}{V_{add}}>t_1\&GreaterEqual;\frac{V_a}{V_{mus}}-\frac{V_a}{V_{add}}$

For the required time t waited for of second time replenishing water tank of water 2 ₂computational methods and t ₁roughly the same, therefore repeat no more in this article.

In the present embodiment, by monitoring bath or moisturizing complete after through time supervision water tank 2 water yield then lower to the requirement of water tank 2 internal environment comparatively speaking, still can obtain the water yield of water tank 2 when being in water tank 2 on the vehicles acutely rocked exactly, being therefore more suitable for the application scenarios under this type of particular surroundings.

In addition, in the present embodiment, can also be carried out monitoring water tank 2 water yield by the hydraulic pressure bottom monitoring water tank 2, concrete monitoring water yield method is multiple in addition, repeats no longer one by one in this article.

5th embodiment of the present invention relates to a kind of chamber pot flushing water method for supplementing water, 5th embodiment is the further improvement of the 4th embodiment, main improvements are, in the 5th embodiment of the present invention: in step s 103, carry out in the process of first time moisturizing at water tank 2 pairs of closets 1, following sub-step can also be comprised: shown in Figure 3, judge whether closet 1 water surface forms water seal by the first sensor 3 be located in closet 1.

If judge, closet 1 water surface forms water seal, then terminate first time moisturizing; If judge, closet 1 water surface does not form water seal, then water tank 2 continues the moisturizing of described closet 1, until the first sensor 3 in closet 1 judges that closet 1 water surface forms water seal.

By this sub-step, can guarantee that in water tank 2, closet 1 water surface can form water seal, eliminate error of calculation, and then prevent that water seal is not in place causes the gas in sewer pipe to spread for a long time.Further, can guarantee when water level after closet 1 blowdown is lower than initial designs water level but higher than critical groundwater table height h ₁time, moisturizing stage first time directly terminates, and then prevents excessive moisturizing.

Same, carry out at water tank 2 pairs of closets 1, in the step of second time moisturizing, also can comprising following sub-step:

Judge whether the closet water surface reaches design initial water level by the second sensor 4 be located in closet 1;

If judge, closet 1 water surface reaches design initial water level, then terminate second time moisturizing; If judge, closet 1 water surface does not reach design initial water level, then water tank 2 continues closet moisturizing, until the second sensor 4 judges that closet 1 water surface reaches design initial water level.

By this sub-step, can guarantee that in water tank 2, closet 1 water surface can get back to design initial water level, eliminate error of calculation, and then prevent the flush cycle of the inadequate position influence next round of water level.Further, can guarantee when after closet 1 moisturizing, water level is higher than initial designs water level, the second time moisturizing stage directly terminates, and then prevents excessive moisturizing.

Persons of ordinary skill in the art may appreciate that the respective embodiments described above realize specific embodiments of the invention, and in actual applications, various change can be done to it in the form and details, and without departing from the spirit and scope of the present invention.
