The present disclosure relates to a suction type toilet with a water turbine or an electric motor as power, and a water turbine and electric motor hybrid power suction type toilet which is completely the same in the part of toilet main body and can be obtained by switching a plurality of related components when the power is changed from the water turbine to the electric motor or from the electric motor to the water turbine.
A pipeline, leading to a sewer, of a toilet basin is provided with a bent structure capable of retaining sealing water and isolating odor of the sewer, and is commonly known as an S-shaped bend. A traditional toilet has two technical defects. Firstly, water resources are greatly wasted, and the fundamental reason is that the traditional toilet is cleaned in a flushing mode, namely, moving clear water is used for impacting a mixture of excrement and urine as wells as sealing water at the position of the S-shaped bend; in this way, clear water and excrement liquid (the mixture of excrement and urine as well as sealing water is called excrement liquid for short) must be mixed in a large scale, in order to ensure that sealing water left at the S-shaped bend is close to clean water after the toilet is flushed, the water consumption must be large, and the larger the water consumption is, the better the effect is. Secondly, the S-shaped bend pipeline is long and zigzag, so that the structure is easy to block, water scale is continuously formed after the pipeline is used for a long time and is difficult to remove, the effective water passing section of the pipeline is continuously reduced, the occurrence rate of blocking is continuously increased, and the water consumption for cleaning the toilet is continuously increased.
In order to achieve sustainable development, water resource waste must be completely eradicated, and a traditional toilet causes the maximum waste of domestic water. The present disclosure aims to overcome the great waste of water resources of the traditional toilet, and the idea of the present disclosure is to reduce the mixing of clear water and excrement liquid to the greatest extent. In the pipeline or the channel, the water at the rear part always follows behind the water at the front part in sequence, so that the water at the front part and the water at the rear part are not mixed. Under this inspiration, when the toilet is cleaned, in order to ensure that clear water and excrement liquid are not mixed, power equipment must be used, a suction mode is adopted, the excrement liquid is forced to run in front, the clear water follows the excrement liquid, and the excrement liquid and the clear water leave the toilet in sequence and fall into the sewer in this mode. The water turbine is firstly selected as the power equipment, the water turbine is the most durable in various power machines, an impeller and a rotating shaft of the water turbine can be completely sealed in the water system, no sealing facility needs to be additionally arranged at the rotating shaft, the water turbine can directly utilize energy of tap water, and the energy of the tap water completely depends on pressure. At present, urbanization is continuously accelerated, new buildings are all high-rise buildings, and tap water needs to be secondarily pressurized, so that a larger space is provided for the novel toilet by taking the water turbine as power. However, due to the fact that the tail end of a tap water pipe network and a water supply pipe network through adoption in indigenous methods in vast rural areas may still be insufficient in pressure, in order to enable a novel water-saving toilet to be universally applicable, a water turbine has to be replaced by an electric motor in places where the tap water supply pipe network is insufficient in pressure. No matter whether the water turbine or the electric motor is used as the power, the main body part of the toilet is completely the same, and when the two kinds of power are replaced, only several related components need to be switched. Therefore, the present disclosure provides a water turbine or an electric motor or a water turbine and electric motor hybrid power suction type toilet, the water turbine or the electric motor can be independently used as a power source, the water turbine and the electric motor can also be selected both, and under different conditions, the electric motor or the water turbine can be manually switched to be used as the power source according to needs. By taking the water turbine or the electric motor as power, the novel water-saving toilet provided by the present disclosure can form the effect at the position of the S-shaped bend that the excrement liquid runs in front and the clear water follows, and the excrement liquid and the clear water fall into the sewer in sequence. Therefore, mixing of the excrement liquid and the clear water is sufficiently reduced, and the effect is that the toilet is flushed clean and the water is saved. The water consumption for urine is less than 1.5 liters, and the water consumption for excrement is less than two liters. People may only defecate once and urinate many times in one day, so that the average water consumption of the toilet each time is no more than 1.5 liters, which is one fourth of the current national forced water consumption standard of 6 liters. The present disclosure further aims to thoroughly change the long and zigzag form of the S-shaped bent pipeline of the traditional toilet, so that the blocking is impossible, and the effect of a water turbine or an electric motor in a water saving mechanism is fully exerted. The present disclosure also provides greater convenience for the user to select the power, and the initial selection can be changed as required even if the toilet is purchased home and installed in place by the user.

The proper position can indicate that the pipe cavity (419) and the part leading to the hollow frame (41) can be hidden, so that the attractiveness or appearance is not influenced. The pipe cavity (419) is provided with a basin bottom water injection valve (415) and a flow rectifying device (412) at the basin bottom water injection hole (43).

Further, a moving contact (85) and a static contact (86), which are associated with the plastic protruding part (84), of an electric motor switch are further arranged outside the water tank. The plastic protruding part (84) is not limited to a plastic material, and may be a protruding part of any material.
The lower part of the toilet is provided with an S-shaped bend different from a traditional toilet, and according to different functions, the whole S-shaped bend is divided into five parts including an S-shaped bend inlet section (44), an S-shaped bend propeller position section (45), an S-shaped bend horizontal overflow port section (46), an S-shaped bend kettle belly accommodating body (47) and an S-shaped bend connecting sewer pipe network section (48).

According to the principle of connecting vessels, the highest water level of sealing water is determined by the position of the horizontal overflow port (51).
Further, the upper end and the lower end of the S-shaped bend kettle belly accommodating body (47) are combined with the upper end and the lower end of the S-shaped bend horizontal overflow port section (46) respectively.

The present disclosure is further described in conjunction with the attached figures and embodiments.
The present disclosure aims to overcome the technical defects that tap water resources for a traditional toilet are greatly wasted and effective service life of the toilet is shortened due to the fact that an S-shaped bend cannot be opened, clamped foreign matters cannot be taken out, water scale cannot be removed and the like. Provided is a water turbine power suction type toilet, tap water drives a water turbine, the water turbine drives a propeller, and a mixture of excrement and urine as well as sealing water at the sealing position of an S-shaped bend is pumped into a sewer. According to the novel toilet, energy of tap water is fully utilized, so that excrement can be easily smashed and sent out of the S-shaped bend. Tap water firstly flows through the water turbine to transfer energy to an impeller, and then enters a basin through water injection holes in the hollow frame of the toilet and a basin bottom water injection hole. Therefore, the effect that the mixture of excrement and urine as well as sealing water is continuously pumped out in front and clear water continuously and sequentially followed is achieved at the position of the S-shaped bend. Therefore, mixing of clear water with the mixture of excrement and urine as well as sealing water is fully avoided, so that the flushing is thorough, and water is saved to the maximum extent. Therefore, scaling is unlikely to occur due to thorough flushing. The installation position of the water turbine becomes an openable position of the S-shaped bend, and even if scaling or clamping of foreign matters occurs, the scalings or foreign matters are convenient to be removed. The novel toilet completely changes long and zigzag form of the S-shaped bend of the traditional toilet, so that blocking is impossible. A main body of the novel toilet, namely a ceramic part, can be used permanently.
The water turbine power suction type toilet is superior to the traditional toilet because the water turbine power suction type toilet can fully utilize energy of tap water and reduce mixing of clear water as well as excrement and urine as much as possible, and therefore efficient water saving is achieved. The key to achieving all the above is not only scientific use of the water turbine, but also all-around innovation of a toilet main body.
As shown in
The lower part of the toilet is provided with an S-shaped bend different from a traditional toilet, and according to different functions, the whole S-shaped bend is divided into five parts including an S-shaped bend inlet section (44), an S-shaped bend propeller position section (45), an S-shaped bend horizontal overflow port section (46), an S-shaped bend kettle belly accommodating body (47) and an S-shaped bend connecting sewer pipe network section (48).
The S-shaped bend propeller position section (45) is a conical pipe with a large upper part and a small lower part. As shown in
The upper end and the lower end of the S-shaped bend kettle belly accommodating body (47) are combined with the upper end and the lower end of the S-shaped bend horizontal overflow port section (46) respectively. The inner diameter of the S-shaped bend kettle belly accommodating body (47) is larger than the outer diameter of the S-shaped bend horizontal overflow port section (46), a cavity is formed between the S-shaped bend kettle belly accommodating body (47) and the S-shaped bend horizontal overflow port section (46), the cavity communicates with the horizontal overflow port (51) and also communicates with the S-shaped bend connecting sewer pipe network section (48).
The upper part of the S-shaped bend kettle belly accommodating body (47) is provided with a component capable of mounting or dismounting the water turbine, so that the upper part becomes an openable part of the S-shaped bend. According to the water turbine as shown in
A tap water inlet (13, 23, 49) is formed in the direction tangential to the side wall of the volute chamber (11, 21), and a volute chamber water outlet (14, 410) is formed in one side of the upper part of the volute chamber (11, 21) from the shaft retaining body (12).
Tap water in the volute chamber (11, 21) transfers most of kinetic energy to the impeller, and the flow velocity v2 at the volute chamber water outlet (14, 410) is much smaller than that v1 at the tap water inlet (13, 23, 49). According to the flow continuity principle v1s1=v2s2, the cross-sectional area s2 of the volute chamber water outlet (14, 410) is much larger than that s1 of the tap water inlet (13, 23, 49).
The impeller of the water turbine is sealed in the volute chamber (11, 21), and the impeller comprises an impeller chassis (15), a blade (17, 22) and a blade upper cover (16) which are fixed into a whole. The blade (17, 22) is a curved surface of which the generatrix is perpendicular to the impeller chassis (15). The blade upper cover (16) is a conical surface, so that the height of a water passage formed by the adjacent blades is gradually increased from outside to inside, so that gradual narrowing of the channel from outside to inside can be compensated, and the cross-sectional area of the channel is kept unchanged.
The upper part of impeller rotating shaft (18, 31, 413) which is fixed to an impeller chassis (15) and rotates synchronously with the impeller extends into the shaft retaining body (12), the lower part of the impeller rotating shaft (18, 31 and 413) penetrates through the volute chamber (11, 21) of the water turbine, and a funnel plugging body (33, 414) and a propeller (32 and 411) are sequentially installed at the lower end of the impeller rotating shaft (18, 31, 413) from top to bottom. The funnel plugging body (33, 414) and the propeller (32, 411) are fixed into a whole.
The funnel plugging body (33, 414) is a slightly tapered circular sleeve with a larger upper part and a smaller lower part, and as shown in
The propeller (32, 411) installed at the lower part of the impeller rotating shaft (18, 31, 413) is positioned at the lower part of the S-shaped bend propeller position section (45). A sharp cutting edge is arranged in front of all blades of the propeller, so that the sharp cutting edge has a propelling function and also has a cutting function.
The volute chamber water outlet (14, 410) of the water turbine is connected with the hollow frame water inlet (42) of the toilet through a hose or other similar objects.
Wherein, the capping screw head (19) not only has an axial limiting effect on the impeller rotating shaft, but also facilitates adjustment of an axial gap, so that the impeller rotating shaft rotates easily. The sealing rubber pad can completely seal the impeller rotating shaft in the water system. The scientific use of the water turbines is as follows: the water turbines in all power machines are most durable and not easy to damage, and can be completely sealed in the water system, so that the worry of water leakage and electric leakage which may occur when an electric motor is used does not exist, and the operation is safe and reliable.
The water turbine power suction type toilet is superior to the traditional toilet also because toilet completely changes long and zigzag form of the S-shaped bend of the traditional toilet, so that blocking is impossible. As shown in
The structure provided with the S-shaped bend horizontal overflow port section (46) and the S-shaped bend kettle belly accommodating body (47) further has the effect that when the toilet is flushed, almost no water exists above the propeller (411), so that backflow does not occur, and sufficient water saving is more facilitated. On the contrary, if a complete upstream pipeline exists above the propeller (411), the water in the upstream pipeline inevitably returns to the sealing position of the S-shaped bend after the toilet is flushed, and in order to enable the return water to be completely clear water, the time to flush the toilet needs to be increased, and thus more water is used undoubtedly.
In all-round innovation of the toilet main body, besides thorough transformation for the S-shaped bend, the crucial transformation is that the basin bottom water injection valve (415) and the flow rectifying device (412) are arranged at the basin bottom water injection hole (43). A pedal valve handle (416) is arranged on the lower part in front of the toilet, and a valve line a (417) and a valve line b (418) extend out of the valve handle at the same time, wherein the valve line a (417) is connected with the tap water supply valve (64), and the valve line b (418) is connected with the basin bottom water injection valve (415). When the pedal valve handle (416) is treaded, under the traction of the valve line a (417) and the valve line b (418), the tap water supply valve (64) and the basin bottom water injection valve (415) can be opened simultaneously. It should be noted that the pedal valve handle (416) is not limited to being arranged on the lower part in the front of the toilet and is also not limited to being in the form of a pedal valve handle, and a manually pressed or any other form of control valve handle can be adopted, for example, an electric button in an electronic or electromagnetic mode is arranged at any appropriate position of the toilet, as long as synchronous control of the tap water supply valve (64) and the basin bottom water injection valve (415) can be realized conveniently. As shown in
The pipe cavity (419) attached to the outer wall of the toilet between the hollow frame water inlet (42) and the basin bottom water injection hole (43) communicates with the bottom of the basin, the liquid levels on the two sides of a connecting vessel are always flush, and in the process of defecation or urination of a person, the mixture of excrement and urine as well as sealing water can enter the pipe cavity (419) at any time to pollute the pipe cavity (419). The pipe cavity (419) cannot be cleaned, and water scale cannot be removed. In order to eliminate the defect, the basin bottom water injection valve (415) is arranged at the basin bottom water injection hole (43), the pedal valve handle (416), the valve line a (417) and the valve line b (418) are utilized, the valve line a (417) is connected with the tap water supply valve (64), the valve line b (418) is connected with the basin bottom water injection valve (415), when the pedal valve handle (416) is treaded, under the traction of the valve line a (417) and the valve line b (418), the tap water supply valve (64) and the basin bottom water injection valve (415) are opened at the same time. Therefore, the tap water supply valve (64) and the basin bottom water injection valve (415) can be synchronously controlled, namely, the work of the water turbine is synchronous with the opening of the basin bottom water injection valve (415), and the stop of the water turbine is also synchronous with the closing of the basin bottom water injection valve (415). Therefore, the basin bottom water injection valve (415) plays two roles: firstly, the mixture of excrement and urine as well as sealing water is prevented from entering the pipe cavity (419), so that the pipe cavity (419) is not polluted and free of water scale; and secondly, after the toilet is flushed each time, the pipe cavity (419) is always filled with clear water, and the clear water is reserved for being used for flushing the toilet next time, so that the time difference between the pumping of the mixture of excrement and urine as well as the sealing water and the following up of the clear water described at present is avoided, and a satisfactory sequential following up effect is formed.
More preferably, as the pressure of tap water is reduced along with the rise of floor of a building, in order to fully improve the utilization efficiency of tap water energy, a pressure energy relay device is arranged at the joint of the tap water pipe network and the water turbine in the present disclosure. As shown in
The pressure energy relay device uses compressed air to store energy, as shown in
In addition, as shown in
In order to improve the universality of the water-saving toilet, the water-saving toilet is suitable for the situation that the tap water pressure is insufficient, the present disclosure also provides a suction type water-saving toilet with an electric motor as power, and the electric motor replaces a water turbine to serve as a suction power source. The power suction type toilet disclosed by the present disclosure can save a large amount of water, the key is in that the suction of the water turbine or the electric motor is utilized to force excrement liquid to run in advance and clear water to follow the excrement liquid, and the excrement liquid and the clear water leave the toilet in sequence and fall into a sewer, so that the mixing of the clear water and the excrement liquid is reduced to the maximum extent. Under a condition that the pressure of tap water is not smaller than 0.35 MPa, the water turbine can be preferentially used as power. As shown in
The water tank is involved when the electric motor is used as power, and as the water consumption of the novel toilet for cleaning each time is only about one fourth of that of a traditional toilet, the water tank can be made into an exquisite and attractive plastic product, which is low in height and is placed at the position of the machine cabin cover, just like a thickened machine cabin cover. The pressure relay energy device does not need to be connected between the water tank and the tap water pipe network, and the connection between the water tank and the tap water pipe network as well as control of water inflow is the same as the traditional toilet, which is not shown here.
The valve handle of the basin bottom water injection valve (415) is located outside the water system, sealing between the valve body and the valve handle is a corrugated pipe made of high-quality silica gel, one end of the corrugated pipe is sleeved on a valve shell opening extending out of the valve handle in a sealed mode, the other end of the corrugated pipe is sleeved on the valve handle in a sealed mode, the corrugated pipe can stretch out and draw back freely like a spring, and the high-quality silica gel can not be damaged for a long time, so that the valve handle can be freely drawn without leakage for a long time.
According to the water turbine and electric motor hybrid power suction type toilet, the working process of the water turbine or the electric motor is divided into two stages. In the first stage, the amount of the mixture of excrement and urine as well as sealing water, namely excrement liquid, is large, and the S-shaped bend inlet is deeply buried below the liquid level, so that the power of the water turbine or the electric motor is fully exerted. Under the condition that the pedal valve handle (416) is treaded, the excrement liquid is almost completely pumped away instantly, and at the moment, clear water injected from the water injection holes in the periphery of the hollow frame (41) and the basin bottom water injection hole (43) does not reach the position of the S-shaped bend inlet. In this stage, large-scale mixing of clear water and excrement liquid is avoided unsurprisingly. However, in the first stage, the excrement liquid cannot be completely pumped away, because the pumping function of the propeller is achieved through atmospheric pressure, when the liquid level of the excrement liquid drops below the upper opening edge of the S-shaped bend inlet, air enters immediately, negative pressure below the propeller does not exist any more, and the pumping function disappears immediately. At this time, the depth of the residual excrement liquid is not enough to bury the S-shaped bend inlet. In the first stage, although large-scale mixing of the clear water and the excrement liquid is avoided, sufficient conditions are provided for small-scale mixing of the clear water and the residual excrement liquid in the second stage. In the second stage, the suction function of the water turbine or the electric motor can be recovered after the water level rises and the S-shaped bend inlet is buried again due to injection of clear water, the power of the water turbine or the electric motor cannot be fully exerted in the stage, and the water turbine or the electric motor can pump away the clear water every time when the clear water is injected. Clear water injected from the periphery of the hollow frame cannot reach the position of the S-bend inlet at the same time, and the flowing direction at the time of arrival is very inconsistent with the flowing direction caused here due to the suction of the water turbine or the electric motor, the injected clear water is very easy to mix with residual excrement liquid, and if no measure is taken, the residual excrement liquid is diluted by continuously injected clean water, the diluted excrement liquid is continuously pumped away, if the finally remaining sealing water becomes clear water, a large amount of clear water needs to be injected, and water waste caused by this small-scale mixing is also considerable. The hollow frame water inlet (42) does not communicate with the hollow frame (41) at the rear part of the toilet directly, so that the water injection mode of the hollow frame into the toilet is improved. The above is the situation before the basin bottom water injection valve (415) and the flow rectifying device (412) are arranged. The small-scale mixing in the second stage can be truly and thoroughly reduced, and the basin bottom water injection valve (415) and the flow rectifying device (412) play a key role. Due to the existence of the basin bottom water injection valve (415), after the toilet is cleaned each time, the pipe cavity (419) is always filled with clear water, the clear water can be reserved for being used for cleaning the toilet next time, and the pipe cavity (419) can be selected to be relatively thick and large, so that more clear water can be contained. The flow rectifying device (412) can adopt a fixed propeller impeller or a spherical circular baffle with densely distributed small holes, and the convex surface of the spherical surface is outwards similar to a shower head used during showering and plays a role in decelerating and expanding the water flow. At the end of the first stage of the operation of the water turbine or the electric motor for cleaning the toilet next time, clear water injected from the basin bottom water injection hole (43) can rush out first due to the fact that the clear water is stored in the pipe cavity after cleaning the toilet last time, and under the action of the flow rectifying device (412), the clear water is spread to fill the channel leading to the S-shaped bend inlet, and residual excrement liquid located in the front is pushed forwards; and before clear water injected from the water injection holes in the periphery of the hollow frame arrives, the residual excrement liquid is completely sent into the S-shaped bend inlet, so that the small-scale mixing is reduced to the maximum extent.
The basin bottom water injection valve (415) further has the function of keeping the pipe cavity (419) clean, if the basin bottom water injection valve (415) is not available, the pipe cavity (419) communicates with the bottom of the basin, the liquid levels on the two sides are always kept flush, in the process of defecation of people, excrement liquid can continuously enter the pipe cavity (419), and particularly when the traditional toilet is blocked, the depth of the excrement liquid in the toilet is the depth of the excrement liquid in the pipe cavity (419). Pollutants on the tube cavity (419) cannot be cleaned, and water scale cannot be removed. This toilet is provided with the basin bottom water injection valve (415) which is opened only when clear water is injected into the toilet from the pipe cavity (419) in the toilet cleaning process, and the basin bottom water injection valve (415) is kept closed at other times, so that neither pollution nor scaling can occur. In addition, the flow rectifying device (412) may be configured to fix in place through a friction force, only this position can be polluted, and therefore the rectifying device (412) is configured to be movable and easy to disassemble, and may be very easily take off every half a year or one year to be cleaned and then installed back, and the scaling is avoided.
The present disclosure relates to a water turbine and electric motor hybrid power suction type toilet which is superior to a traditional toilet, and the key point is that the novel toilet thoroughly changes the long and zigzag structure of an S-shaped bend pipeline of the traditional toilet.
In order to facilitate excrement to pass through the S-shaped bend, the S-shaped bend propeller position section (45) can be specially made into a conical pipe with a large upper part and a small lower part.
The S-shaped bend horizontal overflow port section (46) is an inclined circular pipe, where half of the inclined circular pipe is cut into a horizontal overflow port (51), the S-shaped bend horizontal overflow port section (46) is used for retaining the sealing water, and the position of the horizontal overflow port (51) is a position of the highest water level of the sealing water. However, the S-shaped bend horizontal overflow port section (46) does not only retain the sealing water, and due to the existence of the S-shaped bend horizontal overflow port section (46), the horizontal overflow port (51), the flow deflector (52), the strip-shaped rubber fins (34) and the S-shaped bend kettle belly accommodating body (47) jointly form a perfect combination. The perfect combination has the effects that as long as the fluid crosses the S-shaped bend propeller position section (45), the fluid is thrown into the S-shaped bend kettle belly accommodating body (47) along the flow deflector (52) without being left under the driving of the strip-shaped rubber fins (34), and then automatically falls into the sewer through the S-shaped bend connecting sewer pipe network section (48). Therefore, the toilet can be cleaned only by sending the residual excrement liquid to the S-shaped bend propeller position section (45) by the clear water along with the residual excrement liquid in the second stage of the operation of the water turbine or the electric motor. The length of the propeller position section (45) is less than 4 cm, and the funnel plugging body (33, 414) occupies a considerable position, so that the process can be completed by only needing a small amount of clear water to follow the residual excrement liquid. Therefore, the whole cleaning process is very water-saving.
The strip-shaped rubber fins (34) play a role in accelerating the rotation of the fluid to obtain larger centrifugal force, but do not require the fluid to rotate synchronously with the water turbine or the electric motor. Therefore, compared with blades in the same shape and made of hard materials, the rubber fins (34) have a soft interaction with the fluid, and the noise is low.
The S-shaped bend kettle belly accommodating body (47) also plays another important role. In the first stage of operation of the water turbine or the electric motor, a large amount of excrement liquid is instantaneously pumped away, so that the excrement liquid cannot be discharged by the rear pipeline in time, but the excrement liquid can be instantaneously and completely received by the S-shaped bend kettle belly accommodating body (47) with a larger inner diameter and then slowly discharged into the sewer from the rear pipeline.
In addition, as shown in
The water turbine and electric motor hybrid power suction type toilet is superior to the traditional toilet since the defect that the S-shaped bend pipeline of the traditional toilet is long, zigzag and unopenable is thoroughly overcome. The water turbine and electric motor hybrid power suction type toilet has the advantages that when the toilet is cleaned, excrement and urine are mixed to reach the propeller (411) together with sealing water and undergo a continuous process of smashing, diluting and propelling, and then the mixture is thrown into the kettle belly accommodating body (47) and automatically falls into the sewer through the S-shaped bend connecting sewer pipe network section (48). Intact excrement is present only in the S-shaped bend inlet section (44), so that blocking becomes impossible. The installation position of the water turbine or the electric motor becomes an openable position of the S-shaped bend, and water scale can be thoroughly removed. The propeller position section (45), the horizontal overflow port section (46) and the kettle belly accommodating body (47) can be made of melamine plastic as a whole to be manufactured separately, and the ceramic main body part of the toilet can be used permanently.
More preferably, according to the water turbine and electric motor hybrid power suction type toilet, when the water turbine is used as power, in order to fully improve the utilization efficiency of tap water energy, a pressure energy relay device is arranged at the joint of the tap water pipe network and the water turbine.
