Description

A toilet device, flushing system and flushing method thereof

technical field

This article relates to sanitary technology, especially a toilet device, a flushing system and a flushing method.

Background technique

While existing types of flush toilets are major contributors to a clean and healthy environment, one major disadvantage of flush toilets is long-term water use. In the context of limited water resources and interruptions in supply due to drought or floods, the need for water-saving, hygienic alternatives is evident.

This is urgent in both developing and developed countries, where water for industry competes with water for agriculture, as well as for sanitation and personal use. It is well known that the treatment of wastewater requires both high investment in infrastructure, the process is expensive and in many cases difficult to build infrastructure for sewer systems and treatment plants.

The volume of water required to flush a toilet is usually about 6 liters per flush of solids and liquids. The technique widely used today is to flush the toilet using 2 different flush volumes, one for solids and faeces (full flush) and one for the flush used after the user urinates, a half flush (or economy flush ). This means that when a user uses the toilet to urinate, 3 liters of water are removed with each flush. The cost of flushing toilets is very high. First, the waste water after flushing needs to be treated. Second, the investment in sewer infrastructure. Its operation and maintenance costs also make the cost of cleaning sewers very high.

Due to limited availability of potable water, the industry is developing new technologies to reduce flushing or use non-potable water for toilet flushing.

In the prior art, a flushing technique is used in vacuum toilets, as is used in transportation systems such as trains and airplanes. On the ground, the high investment required to generate the vacuum and the high energy required to operate the system have so far prevented the widespread use of these systems on the ground. There are also new developments in mechanical "flushing", but the investment is high and cleanliness depends on regular maintenance. User acceptance is low due to the different mode of operation from flush toilets. These techniques also have the potential for occasional failure of the odor barrier.

Another widely used flushing technology is the "marine toilet" in recreational shipping. They also have a low flush volume, but are much more difficult to use: before using the toilet, the toilet bowl must be filled with water, which volume must be assessed by the user, and from urination to defecation where the water needs to go from a low fill volume to a high fill volume change. After use the user must refill the reservoir by pressing three buttons. The disadvantage of this system is that it is dependent on the correct operation and correct judgment of the user when all the steps are performed in the correct order. This means that each process is time-controlled and lasts as long as the button is pressed. Another disadvantage is that users are accustomed to operating systems with as many as two flushes after use rather than before and after use.

As shown in FIGS. 1-6 , the embodiment of the present application provides a toilet device 100 , which can be used in a suction smart toilet, which can be a sitting type or a squatting type.

As shown in FIG. 1 , this embodiment is described in detail with a sitting toilet device 100 . The toilet device 100 includes a toilet body 1 and a flushing system 2 installed in cooperation with the toilet body 1 .

As shown in FIG. 2 , the toilet body 1 includes a toilet bowl 10 and a base 11 . The toilet bowl 10 is provided with a first spraying port 101 , a second spraying port 102 , and a sewage discharge port 103 . The first spraying port 101 and the second spraying port 102 are connected with the flushing system 2 for cleaning the toilet body 1, and the sewage outlet 103 is used for connecting with the sewer system to discharge the cleaned contents.

The toilet body 1 includes a front end 1a and a rear end 1b opposite to the front end 1a, and the rear end 1b can be arranged corresponding to the installation surface of the wall. Along the front-rear direction of the toilet body 1 , the first flushing port 101 is arranged at the front of the toilet bowl 10 , and the second flushing port 102 is arranged at the rear of the first flushing port 101 . Along the height direction of the toilet body 1 , the first flushing port 101 and the second flushing port 102 are located at the upper part of the toilet bowl 11 .

In an exemplary embodiment, the first spraying ports 101 include a plurality and are arranged along the circumference of the toilet bowl 10; the second spraying ports 102 include a plurality and are arranged along both sides of the circumference of the toilet bowl 10, so that Can play a better flushing effect.

The toilet bowl 10 has an arc-shaped front portion 104 , an inclined arc-shaped rear slope portion 105 , and a water sealing area 106 at the bottom. The arc-shaped front portion 104 and the inclined rear slope portion 105 form a main chamber extending from top to bottom. The shape of the arc-shaped front portion 104 provides space for receiving urine. Up and down, gradually leaning forward to avoid contact with solid contents during a bowel movement. The water sealing area 106 turns and continues along the lower part of the main chamber and extends toward the rear or side of the toilet bowl 10 . The sewage outlet 103 is located at the rear or side of the toilet bowl 10 and communicates with the water sealing area 106 . The sealed water area 106 has a storage space in the shape of a horizontal column, which can store a certain amount of water, prevent the suction device 12 from contacting with solids, and prevent odorous particles from adhering to the ceramics. The basic water level stored in the sealed water area 106 is connected to the back slope portion 105 of the toilet bowl 10 to fill the diverted space. When flushing, the rising part of the liquid level will level the part between the basic water level and the back slope portion 105 of the toilet bowl , to significantly lift the water. The design of the rear slope 105 can facilitate the accumulation of liquid and paper. The design of the toilet bowl of the embodiment of the present application can significantly raise the water level, gather the contents, and avoid the solid matter sticking to the toilet wall during the sewage discharge process.

The design of the toilet bowl 10 of the embodiment of the present application reduces the demand for higher hydraulic power (flow rate and pressure), and the toilet paper on the slightly descending wet slope can be washed away only by the force of the flushing water flow. In addition, the sealed water area 14 can store a higher water level, and it is easier to wash away the contents.

As shown in FIG. 1 and FIG. 2 , the toilet device 100 also includes a suction device 12 , which is installed in cooperation with the sewage outlet 103 to generate negative pressure to discharge the contents in the toilet bowl 10 . The suction device 12 in this embodiment can be a submerged pump, and a vacuum pump can also be used in other embodiments.

As shown in FIG. 2 , the toilet device 100 also includes an anti-backflow device 13 disposed at the outlet of the suction device 12 , which is an anti-backflow valve used in this embodiment. The suction device 12 is installed in cooperation with the sewage outlet 103 of the toilet body 1 through a flange connector 14, and the flange connector 14 integrates an O-shaped sealing ring and a connecting screw (not shown) fixed to the ground. The suction device 12 can not only suck liquids and solids, but also handle solids and toilet paper, stir them, and shred them.

In this embodiment, the anti-reflux valve 13 is reinforced at the outlet of the suction device 13 by a magnetic element 130 . When the suction device 12 is working, the anti-backflow valve 13 is automatically opened under the push of the inhaled object; after the suction device 13 stops, the anti-backflow valve 13 is automatically closed to seal the toilet bowl 10 and the sewer. The anti-backflow valve 13 is provided with a shut-off device (not shown), so that a rise in the water level on one side of the toilet bowl 10 will not open the anti-backflow valve 13, requiring the pressure of the water column to be higher than the pressure of the blocked water in the toilet to open the anti-backflow valve 13 . The magnetic attraction element 130 is fixed at a predetermined height and is opened at a higher water level, or the discharge system forces it to be opened. The force of the suction device 12 is higher than the resistance of opening the anti-reflux valve 13 to prevent the emulsion from flowing away during the artificial input of liquid or solid. The working time of the suction device 12 is set according to the time of emptying the toilet.

In another embodiment, the magnetic device 130 on the anti-backflow valve 13 will open the anti-backflow valve 13 through the opening circuit of the control device 24 (control device 24 of the flushing system 2 described below).

As shown in FIG. 4 , the toilet body 1 of the embodiment of the present application can be split, including a main body and a base, and the main body and the base can be assembled with each other. The figure is a schematic diagram of the base, and the suction device 12 is arranged on the base, so that it can be quickly adapted to the squatting toilet.

As shown in Figure 1, the flushing system 2 includes a first spray pipeline 21 and a second spray pipeline 22, an on-off assembly 23 connected with the first spray pipeline 21 and the second spray pipeline 22, and The on-off assembly 23 is connected to the control device 24 that controls the opening and closing of the on-off assembly 23. The first spray pipeline 21 is installed in cooperation with the first spray outlet 101 of the toilet body 1 , and the second spray pipeline 22 is installed in cooperation with the second spray outlet 102 .

As shown in Figure 2, the water outlet end (front end) of the first spraying pipeline 21 is provided with a first nozzle 210, and the first nozzle 210 is positioned at the front end of the toilet tank 10 and can flush the toilet paper thrown into by the user's paper. Wash mouth 101 and install. As shown in the figure, the water sprayed by the first nozzle 210 should enter the horizontal columnar storage space of the water sealing area 106 along the curve of the slightly lowered front end of the toilet bowl 10 . The first nozzle 101 has a horizontal section 2101 and a bent section 2102 bent into the toilet bowl 10. The direction of the horizontal section 2101 guides the sprayed water to be delivered horizontally to a position close to the front wall, and the bent section 2102 directs the water to the toilet bowl. 10% wall spraying, can effectively clean the dirt sticking to the inner wall of the toilet. The water outlet end of the second spraying pipeline 22 is provided with a second nozzle 220, and the second nozzle 220 is positioned at the side or back of the toilet bowl 10, and is installed in cooperation with the second spraying port 102 for cleaning the inner wall of the rear portion of the toilet bowl 10 , will likely come into contact with sticky particles for cleaning.

In order to improve the cleaning effect, the first nozzle 210 and the second nozzle 220 can be operated alternately, for example, from left to right, or pulse flushing and the like. According to the available water supply pressure and flow rate, the first nozzle 210 and the second nozzle 220 should be interchangeable, and the spraying angle and spraying direction of the first nozzle 210 and the second nozzle 220 to the cylinder wall can be changed, as shown in Fig. 2 and Fig. 3 As shown, the spraying angle between the second nozzle 220 and the side wall of the toilet cylinder 10 is about 10 degrees, and the spraying coverage range is about 45 degrees, which can be set according to the actual situation. The first nozzle 210 and the second nozzle 220 should integrate threads with sealing rings in order to connect them to the supply pipes of the first spray line 21 and the second spray line 22 . The first nozzle 210 and the second nozzle 220 may be in various shapes such as circular and flat. The first nozzle 210 can completely clean the inner wall of the front of the toilet bowl 10 . The second nozzle 220 is set at an angle so that the flushing range is sufficient to cover the entire toilet bowl 10 .

In order to improve the performance of the cleaning nozzles, the first nozzle 210 and the second nozzle 220 are not fixed on the inner wall of the toilet bowl 10, but are located below the upper edge of the toilet bowl 10, with a small distance from the inner wall, and the spray will not flow parallel to the inner wall, Instead, it forms a certain angle with the inner wall, and the range of spray washing coverage is increased through the angle change, so the cleaning effect of the system can be improved.

The main purpose of the first nozzle 210 is to flush solid objects such as toilet paper thrown in by the user after cleaning with paper after urinating. The first nozzle 210 enters the portion of the sealed water zone 106 along the curve of the slightly lower front end of the toilet bowl. The orientation of the first nozzle 210 directs the jet of water parallel to the surface. The second nozzle 220 mainly cleans the inner wall of the rear portion of the toilet bowl 10 because sticky particles may be contacted. In order to improve the cleaning effect, the nozzles of the second nozzles 220 on both sides are operated alternately (from left to right, or in pulses).

In this embodiment, the on-off component 23 adopts an electric control valve, and the first spraying pipeline 21 and the second spraying pipeline 22 are respectively provided with an electric control valve: a first electric control valve 23a and a second electric control valve 23b. In other embodiments, the first spraying pipeline 21 and the second spraying pipeline 22 may also adopt an integrated electric control valve, which is not limited here.

As shown in Figure 1, the flushing system 2 also includes a pressurizing device 25 located at the first spraying pipeline 21 and the second spraying pipeline 22, which is used for the first spraying pipeline 21 and the second spraying pipe The spray washing water in road 22 is pressurized to provide better flushing effect. The figure shows three waterways A, B, and C as examples of three kinds of water supply, any one of which can supply water to the first spraying pipeline 21 and the second spraying pipeline 22 . Waterway A uses a pressurized water tank for water supply, waterway B uses a booster pump for water supply, and waterway C uses a booster pump and a gas-liquid mixing tank 28 for water supply. The three water supply channels can be used alone or in combination. No limit.

When the pressurizing device 25 adopts a gravity flushing water tank, the water inlet ends of the first spraying pipeline 21 and the second spraying pipeline 22 communicate with the gravity flushing water tank 25 . The gravity flush water tank 25 is suspended at a certain height compared to the toilet body 10 , so that the pressure is only provided by the gravity of the water in the water tank 25 .

When the pressurizing device 25 adopts a booster pump, the booster pump directly pressurizes the water in the first spraying pipeline 21 and the second spraying pipeline 22 .

As shown in Figure 1, the control device 24 includes a control unit (not shown), an operation panel connected to the control unit, and operation buttons (for example: F, M, S, B as shown in Figure 1) are set on the operation panel . The control button can be a physical button or a touch button, can be designed as a piezoelectric switch, or can be designed as a micro switch integrated in the panel. The operation panel can be placed above the toilet body 1, and the switch is connected to a control unit with a program (Arduino) to parameterize different flushing programs. The control device 24 can also be displayed on the terminal through a user interface, which can be a user interface of a sitting or squatting toilet.

In this embodiment, the control device 24 controls the electric control valves 23a, 23b and the suction device 14 to open and close, the time of opening and closing, and the discharge with the toilet bowl according to different flushing command signals received. Empty sequences form multiple flush patterns. In different flushing modes, flushing system 2 achieves effective flushing, emptying, and refilling of the toilet by setting the time sequence to raise the water in the toilet to different levels to maintain the correct ratio of solids and liquids. rinse off.

Prior art toilets typically use two flush modes: one for solids (feces) and one for liquids (urine). Fluid flushes typically contain only half the volume of a full flush, with male and female users typically using between 2.5 and 3 liters per wash. The flushing of the European toilet is regulated by the EN 997 standard, the main flushing water volume is about 6 liters, and the American HET standard is 4.8 liters/flush.

Male and female users are known to act differently after urinating. Those who do not use toilet paper to urinate are usually male users; those who use toilet paper to urinate are usually female users. Since male users flush directly after urinating each time, female users need toilet paper after urinating, which means that female users need more water to wash the toilet paper in the toilet. The advantage is that male users have a water saving potential of about 50% for flushing urine compared to female users, since no water is required to flush the toilet paper. Rinsing water simply rinses the ceramic surface and refills the contents of the water siphon.

Therefore, the toilet device 100 of the embodiment of the present application divides liquid flushing into two flushing modes, the first flushing mode: paperless liquid flushing suitable for men; the second flushing mode: paper liquid flushing suitable for women.

The first mode, a paperless liquid douche for men, works as follows:

After going to the toilet, the user presses the male flushing operation button (the button can be prompted with the symbol M) to trigger the first flushing command (low voltage pulse signal). The control device 24 of the flushing system receives the first flushing command, activates the suction device 12 to suck out the contents, and at the same time, the backflow prevention valve 13 is automatically opened. When the suction device 12 starts and stops after the first predetermined emptying time, the anti-backflow valve 13 is closed to prevent the water from the sewer from flowing back into the water seal area 106 of the toilet.

After the suction device 12 stops for the second predetermined emptying time, the first control valve 23a is opened, the first spraying pipeline 21 delivers water flow, and the first nozzle 210 of the first spraying pipeline 21 discharges water to wet the toilet bowl 10 to clean the front of the water seal area 106 and supplement the water volume of the water seal area 106, the required flushing volume is about 200 milliliters until reaching the first predetermined liquid level L1 to cover the water seal area 106, thereby covering the suction device 12 and the contents parts in contact with objects. Of course, the water volume of the sealing water area 106 can also be replenished through the second spraying pipeline 22 , and the following various modes can supplement the water sealing area 106 through the second spraying pipeline 22 , which is not limited here.

Wherein, the liquid level of the toilet body 1 can be estimated by the opening time of the first control valve 23a, or can be detected by installing a liquid level sensor in the toilet body 1, which is not limited here.

The specific control method of the first mode can refer to Table 1, where X represents the time variable, s represents the second, and the corresponding time can be set through the software. This table is a diagram of a typical flush program logic setup.

Among them, when the toilet is ready to be used, the initial basic water level in the toilet is L1. After the user uses the toilet, the water level rises to LM, and the user presses the flush button to directly perform suction and emptying. After a short period of time, the toilet flushes and fills the water level to L1. The main purpose of setting the rest time is: the filling process can only be started after the process of absorbing excrement is completely completed. There needs to be a short gap in between, otherwise the pump doesn't know when to stop.

The second mode is suitable for women's flushing with paper liquid. The specific operation method is as follows:

Since female users use toilet paper after urinating, these papers are likely to be thrown at the front of the toilet bowl 10, therefore, the amount of flushing water must be such that these paper pieces can be flushed to the water-containing part of the toilet before being discharged. After going to the toilet, the user presses the female flushing operation button (the button can be prompted with a symbol F) to trigger the second flushing command (low voltage pulse signal).

The control device 24 receives the second flushing command, controls the control valve 23a to open the first spraying pipeline 21, and the water flow is sprayed from the first nozzle 210, about 400 milliliters. The first nozzle 210 is installed on the front portion of the toilet bowl 10, close to the front wall of the toilet bowl, so that the toilet paper enters the lower part of the toilet bowl 10 from the front portion of the toilet bowl 10, so that the toilet paper is rushed to the water sealing area of the toilet bowl 10, and the water level rises to At the second predetermined liquid level L2, the paper in the toilet bowl 10 can float on the water surface, and the water level in the toilet bowl 10 is higher than the lower end position of the rear slope portion 105 of the toilet bowl 10 .

When the water level rises to the second predetermined liquid level L2, the control device 24 controls the suction device 12 to open, and the suction device 12 sucks out the liquid with the floating toilet paper. The suction device 12 stops after the third predetermined emptying time, and during the start-up period of the suction device 12, the control device 24 controls the control valve 23a to close. The suction device 12 and the first spraying line 21 work simultaneously for a period of time.

After the water in the toilet bowl 10 is evacuated, the suction device 12 will stop, and the control device 24 controls the control valve 23 to open again to open the first spraying pipeline 21 until the water level in the sealed water area 106 reaches the first predetermined liquid level L1, about 200 ml of water to cover the parts of the suction device 12 that come into contact with the excrement, and the anti-backflow valve 13 is closed to prevent the entry of gas from the waste pipe. The specific control process can refer to Table 2.

Table II

Among them, when the toilet is ready to be used, the initial basic water level in the toilet is L1. After the user uses the toilet, the water level rises to LF. The user presses the flush button to flush, and the water level rises to L2 for suction and emptying. After a short period of time, the toilet Flush fill level to L1.

Analysis of the water used for the second flush mode: Empty volume totals about 200ml of urine, 400ml of water for flushing the paper, 200ml of water for refilling the bottom of the toilet bowl about 800ml.

The toilet device 100 of the embodiment of the present application is also provided with a third flushing mode: it is suitable for men or women to use after discharging solid feces.

The third flushing mode needs to achieve two goals. The first is that when the solid is discharged as a liquid emulsion, more water needs to be added to the toilet bowl 10 to dilute the solid, so the amount of flushing water is higher than that of the second flushing mode. The suction device 12 needs to be activated at the third predetermined liquid level L3; the second is to clean the dirt on the toilet bowl 10 .

The specific operation method is as follows:

After going to the toilet, the user presses the male and female solid (feces) flush button with pressurization function (the button can be indicated by the symbol S) to trigger the third flush command.

The control device 24 receives the third flushing command, and controls the first control valve 23a and the second control valve 23b to open to open the first spraying pipeline 21 and the second spraying pipeline 22 and then close them after a predetermined flushing time. The water flow is sprayed from the first nozzle 210 of the first spray pipeline 21 and the second nozzle 220 of the second spray pipeline 22 to the wall surface of the toilet bowl 10 until the water flow increases to the point that the solid is partially covered by the flushing water and the toilet paper can float. The third predetermined liquid level L3 to a certain extent.

While the water is still flushing in, the suction device 12 starts to suck the contents of the cylinder and stops after a fourth predetermined emptying time. The opening time of the first nozzle 210 and the second spraying pipeline 22 is set as the first predetermined duration when the suction device 12 is working. The first spraying pipeline 21 and the second spraying pipeline 22 stop before the suction device 12 stops, the purpose of which is to make the contents of the toilet bowl 10 be completely sucked out.

After the suction device 12 stops sucking, the first spraying pipeline 21 is opened to fill the toilet bowl 10 with water, and rise to the first predetermined liquid level L1 again. The specific control method can refer to Table 3.

Table three

Among them, when the toilet is ready to be used, the initial basic water level in the toilet is L1. After the user uses the toilet, the water level rises to Ls, the user presses the flush button, the two nozzles flush, the water level rises to L3, and then suction and empty. When emptying, the two nozzles flush for a period of time, and after a short time after emptying, the toilet flushes the filling level to L1.

Water consumption analysis of the third flushing mode: 600ml is used to clean the tank wall and flush the paper, 200ml is used to replenish the toilet and clean the front of the toilet. The input of solid and liquid is about 350ml. Filled water (200ml) stays in the lower part of the toilet bowl for next use. The total volume to be treated is 950 ml of fluid (stool is about 80% fluid).

The toilet device 100 of the embodiment of the present application is also provided with a fourth flushing mode: pressurized flushing suitable for private residences and commercial or public applications.

The fourth flushing mode can be an additional function of the third flushing mode. The main difference from the third flushing mode is that when the fourth flushing mode is turned on, the opening time of the first control valve 23a and the second control valve 23b is extended, approximately 30%, thereby increasing the amount of flushing, while the opening time of the suction device 12 is also relatively extended.

The opening time of the first control valve 23a and the second control valve 23b is defined as the first predetermined flushing time. The opening time of the first nozzle 210 and the second spraying pipeline 22 is set to a second predetermined duration when the suction device 12 is working, and the second predetermined duration is greater than the first predetermined duration of the third flushing mode.

The starting time of the suction device 12 is set as the fifth predetermined emptying time, and the fifth predetermined emptying time is greater than the fourth predetermined emptying time. When the suction device 12 is started and the liquid level reaches the third predetermined liquid level L3, it can be calculated according to the opening time of the first control valve 23a and the second control valve 23b, or can be detected according to the liquid level sensor, which will not be done here. limited.

In addition, the fourth flushing command corresponding to the fourth flushing mode is triggered by the user pressing a flushing button with pressurized flushing (the button can be indicated by a symbol B). The rest of the operation steps of the fourth flushing mode can refer to the third flushing mode, which will not be repeated here.

To avoid the risk of running out of water capacity due to overuse, the flushing system has a reminder function. The first reminding method: by setting the first sensor 26 connected with the control device 24 in the water tank 25 to detect the water level, when the water level of the water tank 25 does not match the water consumption curve, the indicator light reminds. The control device 24 pre-stores the water consumption curve, and collects and calculates the water consumption data of the water tank 25 to determine whether they match. The second reminder method can mark the water level corresponding to the flushing button B in the toilet tank, which is recommended to use pressurized flushing, and it can be prompted by the indicator light. The pressure boost switch B uses the change of the indicator light to prompt the user to operate.

The toilet device 100 of the embodiment of the present application is also provided with a fifth flushing mode: it is suitable for fully automatic full flushing in public or commercial applications where the user is not familiar with the flushing process of the fourth flushing mode, and can be used to treat toilet tanks that are higher than usual. Volume of solids (feces). A larger volume of water (eg, 800 ml instead of 600 ml) needs to be injected due to the greater volume of solids being expelled.

The second liquid level sensor 27 is arranged on the back of the toilet bowl 10 to detect the input solids and liquids, and when the control device 24 receives the input solids and liquids exceeding the predetermined value, it selects to start the fifth flushing mode.

Exemplarily, when about 170g of solid is input, the water level of the toilet bowl 10 will be raised to the high water level of the toilet bowl. If more than 200 ml of urine and more than 170 ml of the usual solids volume, the second level sensor 27 can detect an input above a predetermined level and can adjust the flush volume accordingly, which means that the fifth flush mode will be performed.

The fifth flushing mode can be an automatic flushing mode. The main difference from the fourth flushing mode is that this mode does not require the user to operate buttons, and the fifth flushing command of the control device 24 to open the fifth flushing mode passes the second liquid level. The sensor 27 obtains that when the second liquid level sensor 27 senses that the input solids and liquids in the toilet tank exceed a predetermined value (generally, the water level exceeds a predetermined value), the fifth flushing mode is selected to start.

Start the fifth flushing mode, the control device 24 controls to open the first spraying pipeline 21 and the second spraying pipeline 22 for a second predetermined flushing time, and the second predetermined flushing time is greater than the first predetermined flushing time;

When the liquid level in the toilet cylinder 10 reaches the fourth predetermined liquid level, the control device 24 controls the suction device 12 to start the sixth predetermined emptying time and then stops; close the first spraying pipeline 21 before the suction device 12 stops working and the second spraying line 22 , the first spraying line 21 and the second spraying line 22 continue to be opened for a third predetermined duration at the suction device 12 . The fourth predetermined liquid level is greater than the third liquid level, the sixth predetermined emptying time is greater than the fifth predetermined emptying time, and the third predetermined duration is greater than or equal to the first predetermined duration.

After the suction device 12 stops sucking, the first spraying pipeline 21 is opened again, and the first spraying pipeline 21 is closed when the liquid level in the toilet bowl 10 reaches the first predetermined liquid level L1.

In order to distinguish flush water from rising waste fluid levels in the toilet bowl 10, the second sensor 27 is turned off during flushing operations and top-down inflow (urination). Exemplarily, when the variation of the increase of liquid in the toilet bowl is greater than a preset value, the detection is stopped, and when a flushing signal is received, the detection is started. The rest of the operation steps in the fifth flushing mode may be the same as those in the fourth flushing mode, and will not be repeated here.

Of course, the fifth flushing mode can also be triggered manually, and the corresponding button can be triggered by the user to trigger the fifth flushing signal, which is not limited here.

The water consumption of the fifth flush mode is <1.0 liter/flush. Compared with high-efficiency toilets with US standard 4.8 liters/flush (US HET toilet 1.28 gallons), the water saving effect is about 79%. With a pressurized flush, the water savings are significantly lower at about 1.5 liters/flush, but still about 69% less compared to 4.8 liters/flush.

When any of the above-mentioned flushing modes in the embodiment of the present application is activated, the booster device is required to increase the pressure so that the fluid pressure can be between 1.2 and 4.0 bar. Can adopt gravity water tank 26, increase pump 28 etc. as above-mentioned supercharging device.

When the pressurizing device 26 only adopts the gravity water tank, the water flow pressure of the gravity water tank reaches about 0.15 to 0.2 bar. Flushing performance is reduced as a result, but this can be compensated to some extent by higher flushing volumes and larger flushing tube diameters. The water of gravity water tank 26 can be supplemented by running water, also can collect and filter the water from rainwater collecting tank. In this case, the solenoid valves 23a, 23b can also be operated without backpressure. When the water level is low, the boost function will be turned off.

The applicant has conducted research and proved that the implementation of the toilet device 100 in this application has a high water saving effect. Table 4 is the water saving calculation of 2 adults (male and female) who use the toilet device 100 of the embodiment of the present application for 2 full flushes and 6 times of urination every day, water saving: 82% (water saving without male flushing mode: 77 %).

*Example: One male and one female user per day

As shown in Figure 1, the flushing system 2 of the embodiment of the present application also includes a tank body 28 connected to the first spraying pipeline 21 and the second spraying pipeline 22, and the tank body 28 is used to store gas-liquid with a certain pressure. mixture. The gas-liquid mixture is delivered to the first spraying pipeline 21 and the second spraying pipeline 22 to flush the toilet. On the one hand, the flushing ability is improved, and on the other hand, water can be saved.

In addition, at the same time, a bubble device may be provided at the first nozzle 210 of the first spraying pipeline 21 and the second nozzle 220 of the second spraying pipeline 22 to produce a gas-liquid mixture to achieve the best cleaning effect.

As shown in FIG. 6 , the tank body 28 is made of pressure-resistant steel and has a water inlet and an air inlet (not labeled). An air intake valve is set at the air port, and an air pump and a diversion rubber film box are arranged. With the help of the air pump, compressed air (1.2 to 4.0 bar or higher) can be input into the tank body 28. The effect is that the diversion rubber The membrane box is expanded to the water side by pressurized air and filled to volume with pressurized air. A booster pump is installed at the water inlet, and starting the booster pump will generate a pressure higher than that of the air side to resist the air pressure. Since air is compressible, the water side will compress the air side and fill the container with water at the pressure set by the booster pump.

As shown in Fig. 5 and Fig. 6, the flushing system of the embodiment of the present application can be integrated into a box D, which can realize an integrated, pre-installed one-piece design - plug and play, which can be placed on the floor It can also be installed on the wall of the room. The design is easy to install while allowing one flushing system to be applied to multiple toilets, such as a public toilet box with an integrated plumbing system with a universal inlet connector that can supply water from a push button, side or top. All electronics inside the box are integrated and wired so that the connection of the integrated flushing system to the power supply is also possible to the operating switch (plug). For the external panel, the wiring is pre-installed and the control unit (CPU) is also integrated. In order to ensure a safe space, the tank body 28 can also be "flat" in that its depth needs to be reduced compared to spherical or cylindrical containers. According to the performance of the booster pump, the booster pump can also be installed outside the box. The control unit is also connected to the first level sensor 26, the second level sensor 27 and is used to start and stop the booster pump. When the duration is too long and the risk of bacterial growth rises, the control unit can also initiate a cleaning flush, helping to improve the hygiene of standing water. The flushing system 2 is provided with a plug connector which can be connected with a DC power supply battery for power supply.

The flushing time and emptying time of each flushing mode in the embodiment of the present application can be set. Since the flushing process operates the control valve 23 and the suction device 12 in chronological order, the time setting must be adjustable according to the flushing system. After selecting this mode, the operator can select the start time of each valve/pump after pressing the corresponding start button, as shown in Table 5:

Table five

The program can be done by the remote control or the bluetooth program on the smartphone.

The first predetermined liquid level L1 described in the embodiment of the present application is the initial basic liquid level, the second predetermined liquid level L2, and the third predetermined liquid level L3 are calculated based on the basic liquid level, and are obtained by controlling the opening of the control valve 23 Parameters such as time can determine the second predetermined liquid level L2 and the third predetermined liquid level L3.
