Description

Technical Field

[0001] This utility model relates to the field of horizontal drainage toilet technology, specifically to a flushing and sewage discharge structure and toilet for a horizontal drainage toilet. Background Technology

[0002] Current horizontal flush toilets typically employ a washdown design, which has several significant drawbacks in practical applications. First, washdown toilets are prone to "splashing" during flushing, causing wastewater to splash, which not only affects comfort but may also negatively impact hygiene. Second, "backflow" is another common problem with washdown toilets. Due to their flushing mechanism, waste is not completely expelled, resulting in some waste (low-density suspended solids such as food scraps and toilet paper) flowing back into or remaining in the toilet bowl, reducing cleaning effectiveness.

[0003] To overcome these problems, some designs attempt to enhance the siphon effect by incorporating conventional S-shaped traps into the sewage pipes, aiming to remove waste more effectively. However, even with these measures, blockages can still occur when handling large artificial excrement simulants that meet national standards, demonstrating the design's limited ability to handle larger or irregularly shaped waste. Utility Model Content

[0004] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a flushing and sewage discharge structure for a horizontal drainage toilet and a toilet in which the inner diameter of the horizontal drainage trap gradually decreases along the direction of water flow. When flushing, the flow velocity increases, forming a Venturi effect. After the water flows through the arched middle of the horizontal drainage trap, it falls under the action of gravity, generating a siphon that can quickly discharge the sewage from the inside of the toilet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flushing and sewage disposal structure for a horizontal drain toilet includes a toilet bowl and a horizontal drain trap. The highest point of the pipe in the horizontal drain trap is in the middle, and the middle is arched. The bottom of the toilet bowl is connected to the horizontal drain trap. A side flushing port is provided at the top of the toilet bowl, and a bottom flushing nozzle is provided at the bottom of the toilet bowl. The bottom flushing nozzle is correspondingly located at the inlet of the horizontal drain trap. Both the side flushing port and the bottom flushing nozzle are used to provide flushing water. The inner diameter of the horizontal drain trap gradually decreases along the water flow direction.

[0007] As a preferred embodiment, the horizontal drainage trap includes an inlet section, an arched bend section, and an outlet section connected in sequence. The bottom jet nozzle is correspondingly located at the inlet of the inlet section, and the outlet of the outlet section is connected to a horizontal drainage pipe.

[0008] As a preferred option, the inner diameter of the drainage horizontal pipe is smaller than the inner diameter of the outlet section.

[0009] As a preferred option, the direction of the water jet from the bottom jet nozzle is consistent with the direction of the water flow in the inlet section.

[0010] As a preferred embodiment, the width of the water seal in the horizontal drainage trap is not less than 85mm, the length is not less than 100mm, and the water seal height is greater than 50mm.

[0011] As a preferred option, the inner diameter of both the horizontal drain trap and the horizontal drain pipe is greater than 41 mm.

[0012] As a preferred option, an acceleration device is provided at the bottom jet nozzle to increase the water flow velocity.

[0013] A toilet includes the flushing and sewage discharge structure of the above-mentioned horizontal drainage toilet, and also includes a water tank, the water tank including two water outlet pipes, the two water outlet pipes being respectively connected to a side flush port and a bottom flush jet port.

[0014] This utility model has the following advantages:

[0015] The inner diameter of the horizontal drain trap gradually decreases along the direction of water flow, increasing the flow velocity at the beginning of the trap (Venturi principle). After passing through the arched middle section of the trap, the water falls under the influence of gravity, creating a siphon effect. This siphon further increases the flow velocity before the water flows out of the sewer through the horizontal drain pipe. Because the flow velocity gradually increases within the trap, the force of the water flow is sufficient to carry large pieces of artificial waste and low-density suspended matter into the sewer, thus more effectively propelling waste forward and ensuring its smooth entry into the sewer system. The gradually increasing flow velocity and strong force within the trap easily carry and discharge large pieces of artificial waste and low-density suspended matter, avoiding the clogging problems common in traditional designs.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1

[0021] like Figure 1 As shown, a flushing and sewage disposal structure for a horizontal drain toilet includes a toilet bowl 1 and a horizontal drain trap 2. The highest point of the pipe in the horizontal drain trap 2 is in the middle, and the middle section is arched. The bottom of the toilet bowl 1 is connected to the horizontal drain trap 2. A side flush outlet 3 is provided at the upper part of the toilet bowl 1, and a bottom flush nozzle 4 is provided at the bottom of the toilet bowl 1. The bottom flush nozzle 4 is correspondingly located at the inlet of the horizontal drain trap 2. Both the side flush outlet 3 and the bottom flush nozzle 4 are used to provide flushing water. The inner diameter of the horizontal drain trap 2 gradually decreases along the water flow direction. The inlet of the horizontal drain trap 2 is the water seal point.

[0022] Compared to existing technologies, by increasing the flow rate of water flowing out of the side flush outlet 3 to ensure sufficient flow of the brush ring in the inner bowl 1 of the toilet bowl, and increasing the flow rate of water flowing out of the bottom flush nozzle 4, the water flow rate of the side flush outlet 3 and the jet flow rate of the bottom flush nozzle 4 are sufficient to instantly flush the dirt at the inlet of the water inlet section 5 into the horizontal drain trap 2. The water flow quickly fills the horizontal drain trap 2, and the water flow carrying the dirt flows through the horizontal drain trap 2. The inner diameter of the horizontal drain trap 2 gradually decreases along the direction of water flow, which increases the flow rate of water in the front section of the horizontal drain trap 2 (Venturi principle). After the water flows through the arched middle part of the horizontal drain trap 2, the process of falling under the action of gravity generates a siphon. The siphon effect increases the flow rate of water again, and then flows out of the sewer through the drain horizontal pipe 8. Because the water flow velocity gradually increases within the horizontal drain trap 2, the force of the water flow is sufficient to carry large pieces of artificial excrement and low-density suspended matter into the sewer, thus more effectively propelling waste forward and ensuring its smooth entry into the sewer system. The gradually increasing water velocity within the horizontal drain trap 2 provides sufficient force to easily carry and discharge large pieces of artificial excrement and low-density suspended matter, avoiding the clogging problems common in traditional designs.

[0023] When the water flowing out of the side flush 3 reaches the water seal, the water level rises and forms a vortex. Under the action of the water jet force from the bottom flush 4, the rotating water flow is guided into the horizontal drainage water trap 2, enhancing the sewage discharge efficiency.

[0024] The horizontal drainage trap 2 includes an inlet section 5, an arched bend section 6, and an outlet section 7 connected in sequence. The inlet section 5 is inclined upward along the water flow direction, and the outlet section 7 is inclined downward along the water flow direction. The water flow after passing through the arched bend section 6 generates a gravity drop, which creates a siphon force, reduces water flow resistance, and promotes the rapid ascent of the water flow in the arched bend section 6, further accelerating the flow. The bottom flush nozzle 4 is correspondingly set at the inlet of the inlet section 5. When flushing, the bottom flush nozzle 4 can flush the dirt at the inlet of the inlet section 5 into the horizontal drainage trap 2. The outlet of the outlet section 7 is connected to a horizontal drain pipe 8, which can be connected to the sewer for easy installation.

[0025] The horizontal drain trap 2 and the horizontal drain pipe 8 are collectively referred to as the sewage pipe. The inner diameter of the sewage pipe gradually decreases along the direction of water flow. The Venturi principle causes the water flow velocity in the sewage pipe to gradually increase. The gravity of the arched bend 6 generates a siphon. Under the dual action of the Venturi principle and the siphon, the problem of poor discharge of suspended matter is solved. The inlet pipe diameter of the inlet section 5 is relatively large in order to prevent blockage when flushing away large pieces of man-made excrement.

[0026] The jetting direction of the bottom jet nozzle 4 is consistent with the water flow direction of the inlet section 5, creating a smoother water flow path. This helps reduce energy loss caused by water flow deflection or collision, allowing waste to be discharged more quickly and efficiently. The consistent water flow direction reduces energy loss, lowering the water volume and pressure required to overcome flow resistance, thus achieving energy savings. This consistent flow direction not only promotes rapid waste discharge but also helps remove residues adhering to the inside of the drain pipe. This design, by enhancing the flushing effect of the water flow on the pipe walls, effectively prevents dirt accumulation and further improves overall cleanliness.

[0027] The inner diameter of the horizontal drain pipe 8 is smaller than the inner diameter of the outlet of the water outlet section 7, so that the water flowing out of the water outlet section 7 generates a better Venturi effect in the horizontal drain pipe 8, generating a greater water flow force to discharge the sewage.

[0028] The water seal area refers to the horizontal cross-section of the water seal (i.e., the water-holding part) in the horizontal drain trap 2. The water seal height refers to the vertical depth of the water seal in the horizontal drain trap 2, which is the distance from the water seal surface to the bottom of the water seal. The width of the water seal in the horizontal drain trap 2 is not less than 85mm, the length is not less than 100mm, and the water seal height is greater than 50mm. This ensures a good water seal effect, effectively preventing backflow of sewer gas while maintaining sufficient water volume to maintain sanitary conditions. The inner diameter of both the horizontal drain trap 2 and the horizontal drain pipe 8 is greater than 41mm, ensuring that large pieces of material can pass through the sewage pipe without clogging.

[0029] The bottom-flushing nozzles are equipped with four acceleration devices to increase water flow velocity. These devices maintain efficient rinsing while reducing water consumption. By precisely controlling the speed and direction of the water flow, more effective cleaning is achieved, thereby saving water resources.

[0030] The horizontal drainage trap 2 of the flushing and sewage structure of this utility model has only one arched bend 6, which eliminates the need for complex bends and reduces the obstruction caused by large pieces of man-made excrement.

[0031] Example 2

[0032] A toilet, including the flushing and sewage disposal structure of the horizontal drainage toilet described in Embodiment 1, also includes a water tank. The water tank includes two water outlet pipes, which are respectively connected to a side flush port 3 and a bottom flush jet port 4. The toilet can be a wall-hung toilet or a floor-standing wall-mounted toilet. Because the water flow velocity gradually increases within the horizontal drainage trap 2 and the horizontal drain pipe 8, the water flow force is sufficient to flush large pieces of artificial excrement simulation materials and low-density suspended matter into the sewer.

[0033] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
