Description

Technical Field

[0001] The present invention belongs to the technical field of sanitary ware, and in particular relates to a direct-discharge toilet bowl defecation system and a water-saving sewage discharge method. Background Art

[0002] The squat toilets and toilets in the prior art generally include a water tank, a toilet bowl and a sewage pipe. When sewage needs to be discharged, the sewage is discharged by the pressure generated by the flushing water in the water tank after the sewage pipe is filled with water. The sewage discharge effect is determined by the pressure formed in the sewage pipe, the amount of flushing water and the pressure. Therefore, in order to ensure the sewage discharge effect, the water consumption in the water tank is relatively large, generally 6-8L. In addition, some existing direct-discharge defecation devices, although they do not require a water tank to store water, have the problem of poor sewage discharge effect due to their own structural defects, and their sewage discharge water consumption is generally 4-5L, which is relatively large. Therefore, how to study a defecation system with low water consumption and good sewage discharge effect has become the focus of those skilled in the art. Summary of the Invention

[0061] This embodiment is written in a progressive manner.

[0062] Reference Figure 1-6 , a direct-discharge toilet bowl defecation system, comprising:

[0063] A toilet 3000 is provided with a first sewage pipe 3001-2 at the bottom thereof. One end of the first sewage pipe is connected to a pressure source, and a first valve is provided between the pressure source and the first sewage pipe at the end thereof for controlling the connection or closing of the pressure source and the first sewage pipe.

[0064] A transition pipe having a first connecting end and a second connecting end 1002 , wherein the first connecting end of the transition pipe is connected to the other end (the sewage outlet end) of the first sewage pipe; and the second connecting end of the transition pipe is connected to the sewage main pipe 1003 ;

[0065] A water spraying member provided on the toilet bowl, the water spraying member is used to spray water into the toilet bowl to wet and flush the toilet bowl;

[0066] The blocking mechanism 1000 includes a drain valve 1007 abutting against the inner opening of the transition pipe at the first connection end, and the drain valve is used to control the connection state between the first sewage pipe at the first connection end and the sewage main pipe at the second connection end.

[0067] It should be noted that the pressure source can be a pressure water source or a pressure gas source. The pressure water source refers to water with a certain pressure, which can be the water supply provided by a connected tap water pipe, or the pressurized water provided by a pressure pump added to the municipal tap water pipe; the pressure gas source is a pressure gas source formed by compressing gas in a compressor, or it can be a compressed gas chamber containing compressed gas.

[0068] In the flush-type toilet defecation system of the present application, the water spray component first wets the toilet bowl, which is beneficial for the waste in the toilet bowl to not stick to the toilet bowl and flow into the first sewage pipe; during flushing, the water spray component sprays water and cooperates with the pressure source to punch the first sewage pipe. Preferably, the water spray component and the first sewage pipe are connected to the same pressure water source, and the discharge valve is opened to connect the first sewage pipe with the sewage main pipe, so that the waste in the toilet bowl is flushed out from the first sewage pipe, which has a good sewage discharge effect and effectively saves water; after flushing, the water spray component replenishes a small amount of maintenance water and stores it in the first sewage pipe to prevent odor; the water consumption of the entire flushing and sewage discharge process is 1-1.4L, and the water consumption of each sewage discharge is about 1-1.2L, effectively saving water resources.

[0069] In this embodiment, the transition pipe is preferably a tee structure; one end of the tee is sealed with an end cap 1012, and the other end serves as a first connection end. The end cap preferably has a stepped structure that matches the inner diameter of the tee, and the end cap and tee are secured with bolts 1006 in a manner similar to a flange connection. Preferably, the toilet is a ceramic toilet, protected by a ceramic casing 3001-1.

[0070] As an optional embodiment, the water spraying member includes a water spray pipe 3003 and a nozzle connected to the water spray pipe. The water spray pipe is connected to a water source via a water spray line. The water spray pipe is provided with a water spray valve 4009 (on / off valve) that controls the opening and closing of the water spray pipe. The nozzle is used to spray water supplied by the water spray pipe into the toilet bowl to wet and flush the toilet bowl. In this embodiment, the water spray pipe is arranged around the inner edge of the open end of the toilet bowl, and a water spray groove is provided along the length of the water spray pipe, which serves as the nozzle for spraying water. Alternatively, the water spray pipe has multiple water spray outlets arranged along the length of the water spray pipe, which serve as the nozzle for spraying water.

[0071] As a preferred embodiment, the first connecting end of the transition pipe extends into the other end of the first sewage pipe and is sealed and clamped with the end of the first sewage pipe; this connection method between the first sewage pipe and the transition pipe effectively ensures the sealing performance of the docking between the two and avoids water leakage.

[0072] More preferably, the first sewage pipe includes: an inclined pipe section 3001-4 and a straight mouth section 3001-5 connected to each other; a stamped installation port 3002 is provided at one end of the inclined pipe section in the direction of the central axis, which is used as an installation port connected to the pressure source; the other end of the inclined pipe section is connected to one end of the straight mouth section, and the other end of the straight mouth section is used as a sewage outlet end 3001-3.

[0073] One of the straight section of the first sewage pipe and the first connecting end of the transition pipe is provided with a male stop, and the other of the straight section of the first sewage pipe and the first connecting end of the transition pipe is provided with a female stop that cooperates with the male stop.

[0074] In this embodiment, a female stopper is provided at the sewage outlet end of the straight section, and a male stopper 1001 is provided at the first connection end of the transition pipe. After the sewage outlet end of the straight section is docked with the first connection end of the transition pipe, the male stopper is snapped into the female stopper. Preferably, a first sealing ring 1020 is provided between the male stopper and the female stopper, and the end face of the sewage outlet end and the end face of the first connection end are further provided with bolts to lock and fit together. In the above scheme, the matching method of the male and female stoppers of the transition pipe and the first sewage pipe ensures the tightness of the connection. At the same time, the addition of a sealing ring and further locking by bolts effectively enhances the tightness of the connection between the transition pipe and the sewage pipe. The first sewage pipe and the transition pipe adopt this connection structure, which effectively avoids the problems of poor sealing performance, loose connection, and water leakage in the existing defecation system during application. In this embodiment, the side wall of the transition pipe near the first connection end is also provided with an observation port 1005 for convenient observation of the blockage of the drainage valve. The observation port is provided with a cap. After removing the cap, the blockage of the drainage valve can be observed through the observation port to facilitate maintenance and inspection of the sealing performance of the drainage valve.

The drainage valve is opened, so that the first sewage pipe is connected to the sewage main pipe, effectively flushing the waste in the toilet bowl from the first sewage pipe. The use of air pressure to drain the waste further effectively saves water. After flushing, the flushing valve is closed, and the water spraying part is opened to add a small amount of maintenance water to the first sewage pipe to prevent odor. It should be noted that the compressed air source is compressed by a compressor, and the air path of the flushing valve is connected to the outlet of the compressor; alternatively, the air path of the flushing valve is connected to a compressed air tank or a compressed air chamber.

The water inlet pipe is provided with an inlet valve for controlling the conduction or closure of the pipe, and the water outlet pipe is provided with a water outlet valve 4008 for controlling the conduction or closure of the pipe.

[0085] By controlling the water inflow and outflow of the second chamber, the blocking block is effectively pushed away from the first connection end, and the discharge valve is quickly opened, connecting the first sewage pipe at the first connection end and the sewage main pipe at the second connection end, thereby draining the waste in the toilet bowl. The elastic power member in this application is preferably a spring, and the elastic power member can also be an elastic block made of rubber band material.

[0088] Furthermore, the first connecting end of the transition pipe has an annular protrusion extending into the transition pipe, and the sealing block is provided with an annular groove that engages with the annular protrusion. The coordinated structure of the annular protrusion and the annular groove ensures the tightness of the drainage valve. In this embodiment, the sealing block includes a sealing ring washer 1009, a stainless steel pressure plate 1008, and a clamping plate 1010. One side of the sealing ring washer is provided with an annular groove, within which is an installation inner hole, and the stainless steel pressure plate is arranged in the installation inner hole; the clamping plate is arranged on the other side of the sealing ring washer. With the stainless steel pressure plate sealing the first connecting end, sewage and dirt at the drainage outlet of the first sewage pipe come into contact with the stainless steel pressure plate, which has good strength and corrosion resistance. The sealing ring washer effectively enhances the tightness of the seal. The sealing ring washer is made of elastic silicone or rubber material, the clamping plate is preferably plastic or nylon, and the push rod is preferably made of nylon. The drainage valve with these three components is rationally structured and has excellent properties such as weight, sealing, and corrosion resistance. It is preferred that the stainless steel pressure plate, the sealing ring gasket and the splint are bonded with adhesive, and the sealing block and the push rod are connected with screws; see Figure 2 .

[0089] As a preferred embodiment, the cylinder body 1018 also includes a cylinder cover 1019 connected by threads; one end of the elastic power member abuts the push rod, and the other end of the elastic power member abuts the cylinder cover. One end of the cylinder body is connected to the transition pipe, and the outer wall of the other end of the cylinder body is provided with an external thread extending in the axial direction; the cylinder cover is provided with an internal thread matching the external thread; one end of the elastic power member abuts the push rod, and the other end of the elastic power member abuts the cylinder cover. The cylinder body and the cylinder cover are detachably connected by threads, which, on the one hand, facilitates disassembly and maintenance, and replacement of the elastic power member; on the other hand, by screwing the depth of the threaded connection, the axial length of the cylinder body can be adjusted, and then the elastic contact force applied by the elastic power member-spring can be adjusted. After the elastic power member-spring has been used for a period of time, the elastic force performance of the spring is weakened. By shortening the axial length of the cylinder body, the elastic force can be increased to meet the contact force required by the discharge valve. In this embodiment, the cylinder body is installed on the end cover plate, and the two are fastened with bolts.

[0090] The direct-discharge toilet system of the present application also includes: a sewage separation branch connected to the side of the first sewage pipe; the sewage separation branch is equipped with a sewage separation assembly 2000, which is used to independently discharge sewage containing chemical components and maintenance return water. Sewage containing chemical components is mainly domestic sewage. Domestic sewage such as shower water, laundry water, washing water, and dishwashing water often contains a large amount of chemical components. This chemical sewage is discharged and collected together with urine and feces, which affects the subsequent use of urine and feces.

[0091] Preferably, the sewage separation assembly includes a separation tube shell and a siphon tube assembly arranged in the separation tube shell; a joint 2007 is provided at the bottom of the separation tube shell, and the joint is used to connect to the side of the first sewage pipe; the two side walls of the separation tube shell are respectively provided with a drain port 2006 and a return water port 2005; the siphon tube assembly includes a siphon tube 2002 with dual channels, and a siphon tube sealing cover 2003; one channel of the siphon tube is connected to the joint at the bottom of the installation box, and the other channel of the siphon tube is connected to the separation tube shell; the return water port is connected to the outlet pipe, and a drain pipe 4006 is provided at the drain port, and the drain pipe is provided with a drain valve for controlling the conduction and closing of the pipe.

[0092] In one feasible embodiment, the separation pipe housing includes a mounting box 2004 and a cover 2001. The mounting box has an open top, and the cover is removably connected to the open end of the mounting box. A connector is provided at the bottom of the mounting box for connecting to the side of the first sewage pipe. A drain port and a return port are provided on each side wall of the mounting box. The siphon assembly includes a dual-channel siphon and a siphon sealing cap. One channel of the siphon is connected to the connector at the bottom of the mounting box. The sewage separation assembly uses the siphon principle to discharge domestic sewage from the toilet bowl and the first sewage pipe, separating and discharging domestic sewage through a drain valve connected to a drain pipe. During return flow, the drain valve is closed, and water in the second chamber flows from the outlet through the outlet pipe to the return port of the mounting box. Water discharged from the outlet in the second chamber flows through the return port into the sewage separation assembly, and then flows back to the first sewage pipe through the connector at the bottom of the sewage separation assembly for use as maintenance water. This structural design is both reasonable and compact, significantly saving water.

[0093] A sewage separation branch is set on the side of the first sewage pipe, and the sewage separation branch is preferably arranged on the side of the straight mouth section; when domestic water enters the toilet, the discharge valve is blocked and the sewage outlet of the first sewage pipe is not opened, and the domestic water will flow to the sewage separation assembly. The sewage separation assembly is discharged independently by the siphon principle and discharged from the drain outlet. Since domestic water contains chemical components, the sewage is discharged from the drain pipe to the sewage treatment plant for treatment through the sewage separation branch. In this way, urine and feces are discharged independently from domestic water, which not only uses less water, but also can produce pure feces with less chemical pollution (domestic sewage containing chemical components is separated and discharged), which can be fermented in a septic tank to form an ecological organic fertilizer source, which can be directly used for agricultural production, solving the problem of ecological organic fertilizer resources being hard to come by in my country; replacing existing chemical fertilizers with ecological organic fertilizer sources can reduce the ecological pollution caused by excessive chemical fertilizers, making it green and organic, and more environmentally friendly. In the present application, the sewage pipe at the second connection end is connected to the septic tank, achieving centralized collection and utilization of feces. Preferably, the sewage pipe includes a vertical pipe and an inclined pipe connected to the vertical pipe. The sewage pipe is connected to the septic tank pipe to further connect to the septic tank. The vertical pipe and the inclined pipe are arranged at an angle of 100-150 degrees, preferably 120 degrees, to facilitate smooth transition and discharge of feces.

[0094] After entering the soil, ecological organic fertilizer has a strong chelating effect, which can feed a large number of microorganisms and directly provide nutrients for crop absorption. At the same time, these organic matters are the synthesis of multiple complex acids, which can chelate a large number of elements in the soil. Therefore, when using this organic fertilizer, it can solve the problem of soil microenvironment, as well as the problem of physiological changes in the growth of the aboveground part of the crop. It can also continuously improve the soil and produce some high-quality agricultural products. Ecological organic fertilizer is used to fertilize crops, and the agricultural products produced are green and pollution-free organic products, which greatly improve human life and health. On the other hand, by replacing chemical fertilizers with ecological organic fertilizers, the use of chemical fertilizers can be greatly reduced, thereby greatly reducing the serious pollution in the process of chemical fertilizer reproduction, and further slowing down the undesirable consequences of the depletion of national mineral resources.

[0095] The current excessive use and abuse of chemical fertilizers and chemical pesticides has caused land and water pollution, and the ecological environment has become increasingly severe. Although the use of chemical fertilizers has greatly improved the yield efficiency of crops, it also pollutes land resources and seriously damages soil structure. At the same time, it flows into groundwater, lakes, rivers and oceans during rainy days, causing water resource pollution. Land and water resource pollution has caused an imbalance in the ecological environment and caused huge losses. In the direct-discharge toilet system of the present application, the sewage separation assembly is located in the sewage branch line, which is also connected to the sewage treatment equipment. Bathing water, washing water and other domestic water are separated and discharged through the sewage separation assembly. The domestic sewage with various chemical components flows from the drain outlet to the sewage treatment equipment for further treatment, avoiding its direct discharge into rivers and lakes, reducing water pollution and being more environmentally friendly. That is: by separating sewage into its main components, feces and urine and domestic sewage with chemical components (bathing water, washing water, etc.) are discharged into channels, solving the problem of sewage treatment from the source. Domestic sewage is not directly discharged into rivers and lakes, polluting water sources; fecal water is concentratedly fermented into ecological organic fertilizer with high nutrients and high fertilizer efficiency, turning waste into treasure, helping agricultural development while reducing pollution to the environment.

[0096] As an application embodiment of the direct-discharge toilet defecation system of the present application, the sewage main is connected to the first drainage pipe, which is connected to the septic tank, and the excrement (feces and feces) is discharged into the septic tank for sterilization, storage, and fermentation, thereby generating ecological organic fertilizer for centralized transportation for agricultural production; the drain port of the sewage separation assembly is connected to the second drainage pipe, which is then collected by the second drainage pipe to the urban sewage network and then to the sewage treatment plant for centralized treatment, thereby reducing sewage discharge and pollution to the environment; see for details. Figure 7 The sewage treatment flow chart shown in FIG. In this regard, the present application can also provide a sewage treatment system, including the above-mentioned direct-discharge toilet defecation system, and also including a sewage treatment plant and a septic tank. The connection relationship between the components in the sewage treatment system is specifically referred to in FIG. Figure 7 set up.

[0097] As a preferred embodiment, the in-line toilet system of the present application further includes: a waterway integration joint 4003; the waterway integration joint comprises a four-way pipe joint; one of the four-way pipe joints is connected to the water supply source, the main pressure water source 5001; the remaining three of the four-way pipe joints are respectively connected to the flushing pipe connected to the punching installation port, the spraying pipe connected to the water spraying pipe, and the water inlet pipe 4005 of the second chamber in the cylinder of the sealing mechanism. The four-way waterway integration joint integrates the pipes connected to the punching installation port, the pipes connected to the water spraying pipe, and the pipes connected to the cylinder water inlet hole, creating a compact structure while achieving coordinated coordination of water spraying, cylinder water inlet, and flushing, thereby facilitating sewage control and water conservation.

[0098] The direct-discharge toilet system of the present application also includes a controller 4002 and a sensor. The sensor, flush valve 4007, spray valve 4009, inlet valve, and outlet valve 4008 are all connected to the controller. The controller is used to process sensor information and control the on / off switching of each valve and the coordination of the on / off timing of each valve, thereby effectively achieving water-saving sewage disposal. The controller is preferably a single-chip microcomputer controller or a PLC controller.

[0099] This application sets up a controller and a sensor to realize the automatic control of defecation of the defecation system, which can control the water consumption in a more precise and quantitative manner and save water more efficiently.

[0100] Furthermore, the direct-discharge toilet bowl defecation system of the present application also includes: a blowing mechanism, which includes: a blowing pipeline, and an air outlet connected to the blowing pipeline; the blowing pipeline is connected to the air source chamber, and the air outlet is used to blow out the airflow provided by the air source chamber. Preferably, the air source chamber is a hot air chamber; a blowing valve for controlling the conduction and closing of the pipeline is provided in the blowing pipeline; the blowing valve is connected to the controller. More preferably, the air outlet and the blowing pipeline are connected to a swing arm mechanism that drives them to swing, and the blowing angle is adjusted by the existing swing arm mechanism so that the air outlet blows towards the inguinal crotch of the toilet user; the blowing angle range can be obtained by those skilled in the art based on toilet tests. Furthermore, a directional nozzle is provided in the water spray pipe of the water spray component, and the directional nozzle is used to spray water in a directional manner to the inguinal crotch of the toilet user to clean the stool when the water spray component flushes and discharges sewage; and then cooperates with the air drying mechanism to blow and dry.

[0101] It should be noted that the water spray valve, water inlet valve, water outlet valve, flush valve, drain valve, air flushing valve, blower valve, etc. in the defecation system of this application are preferably solenoid valves; the toilet in this application can be a squat toilet or a sit-down toilet.

[0102] The present application also provides a water-saving sewage discharge method for a direct-discharge toilet system, including a first sewage discharge mode and a second sewage discharge mode. The first sewage discharge mode is used for the discharge and treatment of urine and feces; the second sewage discharge mode is used for the discharge and treatment of domestic sewage with chemical components;

[0103] The first sewage discharge method includes sewage pretreatment and sewage treatment steps;

[0104] The sewage pre-treatment includes: a sensor sensing and transmitting a first sensing signal to a controller to control a water spray valve to open, and connect a water spray pipeline so that the nozzle sprays water to wet the toilet bowl;

[0105] The sewage treatment includes:

[0106] The controller controls the opening of the water spray valve, flushing valve and water inlet valve; the water spray part sprays water and cooperates with the stamping joint to stamp, and the sewage and flushing water are gathered together to the drainage valve at the sewage outlet end of the first sewage pipe, and the drainage valve is opened (the stamping water of the water inlet pipe enters the second chamber to drive the piston rod connected to the drainage valve to overcome the abutment power of the elastic power part to push the drainage valve to open), and the sewage in the toilet bowl and the first sewage pipe is discharged. The sewage in the toilet bowl flows from the first sewage pipe to the sewage main pipe connected to the transition pipe. At the same time, the stamping water pressure flowing into the second chamber has the effect of delaying the closing of the drainage valve, which is conducive to the closing of the drainage valve after the sewage is drained.

[0107] The controller controls the closing of the flush valve and the water inlet valve, and the opening of the water outlet valve. The second chamber is depressurized, and the punching water in the chamber is discharged from the outlet pipe and flows back to the first sewage pipe through the return water port of the sewage separation assembly. The discharge valve is driven by the abutment force provided by the elastic power part to abut and seal the sewage outlet end; the sensor senses again, transmits the second sensing signal to the controller, controls the water spray valve to open, and the nozzle sprays water into the toilet bowl, which forms maintenance water together with the water flowing back from the return water port, and has the function of preventing odor from overflowing.

[0108] Preferably, the water inlet flow of the water inlet valve is substantially equivalent to the water outlet flow of the water outlet valve, so as to simplify the design. The opening time of the water outlet valve in the water outlet pipeline is greater than the opening time of the water inlet valve, so as to empty the punching water in the second chamber.

[0109] The above is the overall discharge treatment process for feces, while for urine discharge treatment, the sewage pretreatment step is omitted to further save water; and in the flushing process after urination, only the water spraying part can be used for flushing, and the water inlet valve is coordinated to open the discharge valve to achieve urine flushing; the water inlet valve is closed, the water outlet valve is opened to discharge water, and while the discharge valve is closed, the water outlet of the outlet pipe flows back to the sewage pipe section to become maintenance water, further reducing the amount of water sprayed by the water spraying part for maintenance water, significantly saving water. That is, the direct-discharge toilet defecation system of the present application has different water consumption for flushing urine and feces, with the water flushing volume of 1-1.4L for feces and 0.7-0.9L for urine. The direct-discharge toilet defecation system of the present application consumes less water for flushing urine and feces, saving water resources, and also avoiding: the existing system consumes a lot of water for flushing, too much water mixed with urine and feces reduces the fertilizer value of feces, and increases the burden of subsequent fermentation treatment.

[0110] The second sewage discharge method includes: closing the spray valve, flushing valve, water inlet valve and outlet valve, opening the drain valve of the sewage separation assembly, and with the help of the siphon principle, the sewage in the first sewage pipe of the toilet is discharged from the drain outlet; the controller controls the closure of the drain valve and at the same time controls the opening of the spray valve, and the nozzle sprays water into the toilet to form maintenance water.

[0111] See also Figure 6This embodiment uses a sit-down toilet as an example. The toilet bowl is a ceramic bowl, comprising a ceramic bowl and a ceramic shell. The bowl is housed within and protected by the ceramic shell. A flip-top toilet lid (toilet cover) is provided on the ceramic shell. The toilet lid 4001 is connected to the ceramic shell housing the bowl in accordance with existing flip-top structures.
