Description

Technical Field

[0001] The present invention relates to a sanitary ware, in particular to a sewage pipe water seal card on a siphon sewage pipe body is horizontally arranged on the side of the toilet bowl bottom, and a high-speed large water flow flushed out by an auxiliary flushing injection hole is used to strongly spray the sewage pipe inlet, and a siphon water resistance section arranged after the sewage pipe water seal card immediately generates a strong siphon force in the siphon negative pressure section, so that a strong siphon replacement effect is achieved at the bowl bottom inlet, thereby solving the problems of shallow bowl bottom, loud noise, high water consumption, poor replacement effect and production process existing in existing squat toilets with water traps and squat toilets without water traps. Background Art

[0002] Squat toilets are particularly popular in areas south of the Yellow River, and my country currently has nearly 300 million squat toilets installed.

[0003] In daily use, people clearly know that squat toilets have problems such as shallow bowls, small water storage area, loud noise, high water consumption, and floating objects that cannot be flushed away, compared to toilets. However, these problems have not changed for decades and remain the same today.

[0004] In the sanitary ceramics industry, there are only two recognized methods of sewage replacement. The first is siphon replacement, which uses the water level difference between the sewage pipe inlet and the sewage pipe outlet to generate a negative pressure siphon function on the upper part of the sewage pipe to suck away the dirt. It has the significant advantages of thorough replacement, water saving and quietness, but the sewage pipe cannot be too thick, because the siphon is restricted by the total water volume and the kinetic energy of the water flow, and the diameter of the sewage pipe can only be controlled within 58 mm. Most toilets use siphon replacement; the second is direct drop replacement, which relies on the strong kinetic energy of water to evenly flush the entire water storage surface and force the dirty water and dirt out of the sewage pipe. Its product advantages are simple manufacturing structure, thick sewage pipe diameter, and the sewage pipe inlet looks large, but the bottom of the toilet bowl is shallow, floating objects cannot be flushed away, water consumption is high, and noise is high. At present, all squat toilets on the market use this method.

[0005] Why have squat toilets produced by the entire ceramic industry adopted the direct-drop replacement method for decades? It is because the designers of the ceramic industry lack comprehensive and in-depth research on architectural design, installation process and product structure design.

[0006] The national construction industry standard for the depth of the sink in the bathroom is 400 mm, the outer diameter of the sewage pipe interface is 110 mm, and the distance between the lower edge of the horizontal sewage pipe interface and the bottom plate of the sink is 60-80 mm. In other words, the height of the squat toilet ceramic plus the total height after the installation of the 110 mm horizontal pipe is only 320-340 mm. If the height exceeds this range, the squat toilet cannot be installed.

[0007] There are two types of squat toilets on the market now: squat toilets with traps and squat toilets without traps.

[0008] As mentioned above, there are two types of replacement methods for sanitary ware: siphon type and direct drop type. The siphon type has many more advantages than the direct drop type. Why don't squat toilets use the siphon type replacement method? The reasons are as follows:

[0009] First of all, it should be noted that the design of the siphon drain pipe of the sanitary ware must meet the following conditions to achieve a better siphon effect: first, there must be a drop between the drain pipe inlet and the drain pipe outlet; second, there must be a water resistance bend at the end of the drain pipe to quickly form a negative pressure siphon in the drain pipe; third, the diameter of the drain pipe must match the water supply flow and the kinetic energy of the water flow.

[0010] The current structure of squat toilets with traps on the market is: the sewage pipe of the squat toilet is symmetrically designed under the bottom of the toilet bowl, and the outlet of the sewage pipe faces downward. In order to facilitate the insertion of the sewage connection pipe with an outer diameter of 110 mm, the outer diameter of the end of the tapered outlet is about 90 mm. Excluding the thickness of the ceramic tube wall, the inner diameter of the sewage pipe outlet is about 70 mm, and the upper diameter of the cone is larger. The inner diameter of the 110 mm outer diameter pipe is 104 mm, so the diameter of the upper end of the cone must be greater than 104 mm, otherwise it will not be installed tightly. If the installation height is considered: the installation height available for the standard sinking tank is only 320-340 mm, the sewage connection pipe occupies 110 mm, and the right-angle elbow of the pipe must be shortened to leave at least 10 mm of sealing length. The ceramic wall thickness at the bottom of the sewage pipe inlet is 10 mm, and only the 50 mm sewage pipe diameter is counted. The inner diameter of the sewage pipe water seal card is only 45 mm, the ceramic wall thickness at the water seal card is 10 mm, and the national standard water storage depth of 50 mm, the above together account for 285 mm in height. In this way, even the height of the designed water guide ring is not high, because the narrowest water guide ring also requires a 40 mm outer diameter of the pipe wall, not to mention what height is there to design the bottom of the toilet bowl. Through the above precise calculations, we can conclude that any product with a total ceramic height of more than 220 mm on the current squat toilets on the market cannot be installed in the national standard sinking tank. The actual solutions to the problem are to raise the ground, press the connecting pipe downward, or add a step. Many manufacturers make the pipe diameter narrower, the water seal smaller, the water storage shallower, and the basin bottom flat. The most common problem in the market is that squat toilets cannot be installed. As for the siphon squat toilet, if the current sewage pipe structure is not changed, none of the three conditions for the formation of siphon will be met.

[0011] The current squat toilet structure without a trap on the market is: a squat toilet always needs a trap to isolate odors, and a squat toilet without a trap simply uses the trap as another separate accessory, which is then sealed and connected during installation. This separate trap outlet discharges water horizontally, which helps alleviate the problem of the squat toilet being unable to be installed, but the bottom of the toilet bowl cannot be made too deep, and the diameter of the trap cannot be made too thick, otherwise it will also affect the installation height. For this squat toilet structure without a trap, the water seal position of the trap can only be designed below the bottom of the toilet bowl, and there is no water at all in the bottom of the toilet bowl. If you want to consider designing a siphon-type sewage replacement method, there is no high-design water resistance bend to help form a negative pressure siphon in the sewage pipe.

[0012] How to improve the current squat toilet structure to achieve siphon replacement, optimize the design without changing people's installation habits and simplifying the production process? I made the following discussion. Summary of the invention

[0013] The present invention relates to a sanitary ware, in particular to a sewage pipe water seal card on a siphon sewage pipe body is horizontally arranged on the side of the toilet bowl bottom, and a high-speed large water flow flushed out by an auxiliary flushing injection hole is used to strongly spray the sewage pipe inlet, and a siphon water resistance section arranged after the sewage pipe water seal card immediately generates a strong siphon force in the siphon negative pressure section, so that a strong siphon replacement effect is achieved at the bowl bottom inlet, thereby solving the problems of shallow bowl bottom, loud noise, high water consumption, poor replacement effect and production process existing in existing squat toilets with water traps and squat toilets without water traps.

[0014] As mentioned in the previous section: All current squat toilets in the sanitary ceramics industry have the sewage pipe set in the central position under the toilet bowl, the sewage pipe water seal is located very low, and the sewage pipe outlet is a conical ceramic outlet with an inner diameter of about 70 mm. This structural layout of the sewage pipe determines that squat toilets can only use a straight-down replacement method. If you want to improve the replacement effect, you must start by changing the structure of the sewage pipe and the flushing flow system. The most reliable solution is to refer to the sewage pipe structure of the siphon toilet.

[0015] The above technical problems of the present invention are solved by providing a squat toilet with a horizontal siphon sewage pipe, which includes a squat toilet body, a water inlet interface, an auxiliary flushing water guide pipe, a washing water guide ring, a washing hole, a toilet bowl bottom, a frame, an auxiliary flushing jet hole, a bowl bottom inlet, a sewage pipe inlet, a sewage pipe water seal card, a sealing card slot, a sewage pipe outlet, a siphon water resistance section, and a siphon negative pressure section. The characteristic of the squat toilet is that the sewage pipe water seal card on the siphon sewage pipe body is horizontally arranged on the side of the toilet bowl bottom, and the high-speed and large water flow flushed out of the auxiliary flushing jet hole is used to strongly spray the sewage pipe inlet. The siphon water resistance section arranged after the sewage pipe water seal card immediately generates a strong siphon force in the siphon negative pressure section, so that a strong siphon replacement effect is achieved at the bowl bottom inlet, thereby solving the problems of shallow bowl bottom, high noise, high water consumption, poor replacement effect and production process existing in the existing squat toilets with water traps and squat toilets without water traps.

[0016] Optionally: the sewage pipe water seal card on the siphon sewage pipe body is set on the left or right side of the bottom of the toilet bowl, and the angle formed with the frame can be arbitrarily designed according to the need for convenient mold opening.

[0017] Optional: The height of the sewage pipe water seal card position can be arbitrarily selected according to the depth of water stored at the bottom of the toilet bowl.

[0018] Optionally: The diameter of the main body of the siphon sewage pipe is designed according to the flow rate and kinetic energy of the water inlet interface, and its internal diameter is controlled between 41 and 55 mm.

[0019] Optionally: the bending shape and structural orientation of the siphon water resistance section on the siphon sewage pipe body are not restricted.

[0020] Optional: The water outlet direction of the sewage pipe outlet is not restricted.

[0021] Optional: The size and shape of the basin bottom inlet and the setting orientation of the sewage pipe inlet are not restricted.

[0022] Optionally: the size, shape, distance from the sewage pipe inlet and direction of the auxiliary injection hole are not restricted.

[0023] Optionally, the main body of the siphon sewage pipe can be connected in sections in a specific production mold structure, or the main body of the siphon sewage pipe is composed of a sectioned combination structure of different materials.

[0024] Compared with the existing squat toilets with or without water traps on the market, the squat toilet with a horizontal siphon sewage pipe of the present invention has the following advantages:

[0025] 1. It raises the height of the sewage pipe water seal card, creating conditions for the design of a siphon sewage pipe. The current sewage pipes of squat toilets with water traps are all located on the central axis below the bottom of the toilet bowl. The height of the sewage pipe water seal card is restricted by the height of the bottom of the toilet bowl. If the sewage pipe water seal card is designed to be high, the total height of the ceramic body will increase, and the squat toilet cannot be installed. The current squat toilets without water traps do not have their own sewage pipes. They are formed by a separate water trap elbow and then connected to form an odor barrier. The sewage pipe water seal card is closer to the bottom of the sink. Because the sewage pipe water seal cards of these two squat toilets are located at a very low position, it is impossible to design the sewage pipe water resistance section like the toilet sewage pipe, and it cannot be designed as a siphon sewage pipe, so only a straight drop replacement method can be used. Although the sewage pipe of the vertical replacement is relatively thick, the water storage depth at the bottom entrance of the toilet remains unchanged. Dirty water and dirt are completely smashed down by strong water flow, so it consumes a lot of water, makes a lot of noise, splashes seriously, and floating objects are difficult to flush away. The horizontal siphon sewage pipe squat toilet of the present invention sets the siphon sewage pipe body horizontally to the left or right side of the frame. The height position of the sewage pipe water seal card is no longer restricted by the bottom of the toilet bowl. The position of the sewage pipe water seal card can be raised as much as possible, as long as the sewage pipe is not exposed higher than the ceramic panel. In this way, the bottom of the toilet bowl can be greatly deepened, and the anti-splashing performance is enhanced during flushing; after the position of the sewage pipe water seal card is raised, there is enough space height to design the water resistance section of the sewage pipe, and the siphon sewage pipe can be designed like a toilet.

[0026] 2. The inner diameter of the sewage pipe outlet is reduced, which creates conditions for the siphon negative pressure section of the siphon sewage pipe body to quickly form a strong negative pressure. The current squat toilets with water traps and squat toilets without water traps are both straight-drop replacement methods. The diameter of the sewage pipe outlet is thick, generally 70 mm, because the conical ceramic outlet is to be directly connected to the 110 mm thick sewage connection pipe. If the ceramic pipe diameter is too small, it will not be tightly connected. Furthermore, the basin bottom inlet of the straight-drop replacement method is always full of water, and the replacement of dirt depends entirely on the large water flow to force it out. If the sewage outlet pipe is not rough, it will seriously affect the discharge of dirt. The design principle of the siphon sewage pipe is fundamentally different from the straight-drop replacement method. In addition to requiring a height difference in the water flow, it must also achieve full water supply, and the water resistance bend must be used to press the air at the upper end of the sewage pipe out to form a better siphon effect. According to the current flow calculation of squat toilet water tank water supply, although the water tank is located at a high position and the potential energy of the water is large, the inner diameter of the pipe at the water inlet interface is only 38 mm. For this reason alone, if it is to be designed as a siphon type sewage pipe, in order to achieve full water supply in the sewage pipe, the sewage pipe outlet cannot be made thicker. The diameter of the sewage pipe main body of the horizontally placed siphon sewage pipe squat toilet of the present invention is designed according to the flow rate and kinetic energy of the water inlet interface, and its inner diameter is controlled between 41 and 55 mm, which can not only realize sewage discharge when the sewage pipe is full of water, but also squeeze out the air in the negative pressure area of ​​the sewage pipe through the siphon water resistance bend to quickly realize the siphon effect. What is more outstanding is that the characteristic of the thinner sewage pipe outlet can be utilized to make the lowest edge of the inner wall of the sewage pipe outlet flush with the lowest edge of the inner wall of the 110 mm thick sewage connecting pipe when it is sleeved. In this way, the water flow height difference between the sewage pipe inlet and the sewage pipe outlet is increased, which is of great help to achieve a good siphon effect.

[0027] 3. Changing from straight-drop replacement to siphon replacement creates conditions for completely solving the defects of the current squat toilet replacement. The current squat toilets with water traps and squat toilets without water traps are all straight-drop replacement methods. First, the diameter of the sewage pipe outlet is large, generally with an inner diameter of 70 mm, and the diameter of the water supply pipe cannot meet the drainage flow of the sewage pipe at all; second, there is almost no water flow height difference between the sewage pipe inlet and the sewage pipe outlet; third, there is no water resistance bend designed with a height difference at the end of the sewage pipe; fourth, there is no strong water flow at the sewage pipe inlet to help form a negative pressure siphon; therefore, the current squat toilet replacement methods on the market are all straight-drop replacement, so replacement problems such as high water consumption, high noise, serious splashing, and difficulty in flushing away floating objects always exist. The horizontally placed siphonic sewage pipe squat toilet of the present invention arranges the sewage pipe water seal clamp on the siphon sewage pipe body horizontally on the side of the toilet bowl bottom, so that the sewage pipe water seal can be raised, and the inner diameter of the entire sewage pipe is controlled between 41 and 55 mm. By optimizing the sleeve connection mode of the sewage pipe outlet and the sewage connection pipe, the water flow height difference between the sewage pipe inlet and the sewage pipe outlet can be further increased, creating conditions for designing a siphon water resistance bend at the end of the sewage pipe; the high-speed and large water flow flushed out by the auxiliary flushing injection hole is used to strongly spray the sewage pipe inlet, and the siphon water resistance section arranged after the sewage pipe water seal clamp immediately generates a strong siphon force in the siphon negative pressure section, thereby well solving various replacement performance problems existing in the existing squat toilets, the water consumption can be reduced from 6 liters to 4 liters, the noise is reduced from more than 70 decibels to more than 50 decibels, the basin bottom is deepened by one third, the splashing index is fully qualified, and floating objects are easily and immediately washed away.

[0028] 4. The siphonic sewage pipe adopts a horizontal structure, which creates conditions for simplifying the production process of siphonic squat toilets and improving the product qualification rate. Squat toilets are simple-process products among sanitary ceramic products and are classified as small items. The main reasons are simple product structure, small ceramic volume and low sales price. In people's lives, especially in the southern region, squat toilets are more likely to be used than toilets. Therefore, the poor replacement performance of the current squat toilets is the most after-sales feedback problem and has not been solved. From a design perspective, the total height of the ceramic of the toilet is generally 380-400 mm, and most products are siphonic replacement methods; the national standard reserved depth of the bathroom sink is also 400 mm, so why can't a siphonic sewage pipe be designed? I think that firstly, the rigid structure of the current squat toilet has imprisoned people's thinking, making them think that the sewage pipe design under the toilet bowl is the simplest and most scientific; secondly, they think that the connection method between the ceramic outlet of the squat toilet and the sewage connecting pipe can no longer be changed; thirdly, they don't know that the siphon sewage pipe is much thinner, and there is a way to further raise the water flow height difference between the sewage pipe inlet and the sewage pipe outlet during installation; fourthly, when the squat toilet is installed, the water tank is destined to be in a symmetrical position with the ceramic, and the sewage pipe buried under the ground suppresses the height forward and affects the mold opening of the water inlet interface structure backward. The squat toilet with a horizontally placed siphonic sewage pipe of the present invention breaks the traditional inherent design mode starting from the structure of the ceramic body, comprehensively considers the above-mentioned various factors, especially the sewage pipe water seal card on the siphon sewage pipe body is horizontally arranged on the side of the toilet bowl bottom, so that the sewage pipe water seal card is no longer restricted by the height of the toilet bowl bottom; the ceramic sewage pipe is designed as a siphon sewage pipe body according to the standard of a toilet, and the entire pipeline becomes thinner. Since the water flow saturation requirement for forming a siphon is met, the water level difference between the sewage pipe inlet and the sewage pipe outlet is increased, and it is also convenient to design a siphon water resistance bend for quickly forming a siphon; an auxiliary flushing injection hole is arranged at the water storage depth of the basin bottom inlet, and the water pressure potential energy of a higher water tank is converted into the water kinetic energy for quickly forming a negative pressure siphon, thereby obtaining a siphon effect better than the performance of a toilet; the siphon sewage pipe body is horizontally placed on the toilet bowl bottom structure, which provides a new mold structure method for not changing the current ceramic installation form and convenient, fast and stable molding and blanking, thereby improving the product production qualification rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] Figure 1 It is a schematic diagram of the structure of a squat toilet with a horizontally placed siphon sewage pipe according to the present invention.

DETAILED DESCRIPTION

[0032] Figure 1 The specific implementation of the squat toilet with a horizontal siphon sewage pipe of the present invention is shown. The water inlet interface 2 on the squat toilet body 1 is connected to the frame 7, the washing water guide ring 4, and the auxiliary flushing water guide pipe 3. The washing holes 5 are supplied with water by the washing water guide ring, and the auxiliary flushing injection holes 8 are supplied with water by the auxiliary flushing water guide pipe 3. A toilet inlet 9 is opened at the lowest point behind the toilet bottom 6, and auxiliary flushing injection holes 8 are symmetrically arranged at both ends to spray water toward the sewage pipe inlet 10. The siphon sewage pipe body 16 is horizontally arranged on the left or right side of the toilet bottom 6, and the sewage pipe water seal card 11 can be arbitrarily designed at the left or right side of the toilet bottom 6 as needed. A siphon water resistance section 14 is designed between the sewage pipe water seal card 11 and the sewage pipe outlet 13, and its curved shape is determined according to the need for the siphon negative pressure section 15 located at the upper end of the sewage pipe water seal card 11 to quickly form negative pressure. A sealing groove 12 is designed on the upper part of the sewage pipe outlet 13 for sealing when the sewage pipe is connected with the sewage connection pipe.

[0033] The following options can be flexibly handled in specific design:

[0034] 1. The drainage pipe water seal card 11 on the siphon drainage pipe body 16 is set on the left or right side of the toilet bowl bottom 6, and the angle formed with the frame can be arbitrarily designed according to the need for convenient mold opening. Horizontal placement is just a design concept, which can also be considered as offset. When the offset reaches a certain degree, the drainage pipe inlet 10 can even keep the current squat toilet structure unchanged, and the siphon drainage pipe body 16 can be bypassed to the side of the toilet bowl bottom 6.

[0035] 2. The height of the sewage pipe water seal card 11 can be arbitrarily selected according to the need for the depth of water stored in the toilet bowl bottom 6. During the design, the depth of the toilet bowl bottom 6 should also be considered according to the total depth of the sinking tank.

[0036] 3. The diameter of the siphon sewage pipe body 16 is designed according to the flow rate and kinetic energy of the water inlet interface 2, and its internal diameter is controlled between 41 and 55 mm. If the pipe is too thin, it is easy to be blocked during use, and if the pipe is too thick, the water supply system cannot meet the conditions for forming a negative pressure siphon in the pipe.

[0037] 4. The bending shape and structural orientation of the siphon water resistance section 14 on the siphon sewage pipe body 16 are not restricted.

[0038] 5. The water outlet direction of the sewage pipe outlet is not restricted. If the mold opening process allows, even the horizontal water outlet pipe can be directly generated on the sewage pipe outlet 13.

[0039] 6. The size and shape of the basin bottom inlet 9 and the location of the sewage pipe inlet 10 are not restricted.

[0040] 7. The size, shape, distance and direction of the auxiliary jet hole 8 from the sewage pipe inlet 10 are not limited. If necessary, the sewage pipe inlet 10 can also be sprayed obliquely.

[0041] 8. The siphon sewage pipe body 16 can be connected in sections in the specific production mold structure; or the siphon sewage pipe body 16 is composed of a section combination structure of different materials.

[0042] When people start flushing: people press the flush button, and the water flow with a water level of nearly 1 meter rushes into the water inlet interface 2 with strong kinetic energy. Only a small part of the strong water flow of the water inlet interface 2 supplies water to multiple small washing holes through the washing water guide ring 4, and the water flow after washing the toilet bottom 6 causes the water storage surface of the basin bottom inlet 9 to rise rapidly; at the same time, most of the strong water flow is sprayed toward the sewage pipe inlet 10 through the auxiliary flushing water guide pipe 3 and the auxiliary flushing injection hole 8, and the siphon negative pressure section 15 above the sewage pipe water seal card 11 is quickly filled with water. When the large water flow passes through the siphon water resistance section 14, due to the obstruction of the water flow, a small amount of air in the siphon negative pressure section 15 will be squeezed out. Due to the water level difference between the sewage pipe inlet 10 and the sewage pipe outlet 13, the water flow speed discharged from the sewage pipe outlet 13 is faster. At this moment, negative pressure is immediately generated in the siphon negative pressure section 15, and the dirty water and dirt in the basin bottom inlet 9 are instantly sucked clean.

[0043] Of course, the horizontal siphon sewage pipe squat toilet of the present invention can also have many changes and modifications, and is not limited to the specific structure of the above-mentioned embodiment, such as the siphon sewage pipe body is offset at different angles and various changes in the structural form of the toilet bowl. In short, the protection scope of the horizontal siphon sewage pipe squat toilet of the present invention should also include those obvious exchanges, substitutions and modifications to ordinary technicians in the field.
