Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of bathroom, and relates to toilet sewage structure, concretely relates to a sewage structure of flush toilet. BACKGROUND

[0002] The flush toilet is used to discharge sewage by the force of water flow. Since the flush toilet is used to discharge sewage by the force of water flow, the pot is usually set steeply, so that the water flow can impact the bottom of the toilet, forming a large force. However, the steep structure of the pot also causes a dead angle at the joint of the pot and the sewage structure, which easily causes the toilet to be blocked. Moreover, the sewage structure is also limited by the steep structure of the pot, causing the bend at the bottom to have a large bending angle. When flushing sewage, the water flow will collide with the sewage structure, causing the force to be damaged, so that the local resistance coefficient of the bend is large, thereby affecting the flushing and sewage effect of the toilet and easily causing blockage. If the structure of the joint of the pot and the sewage pipe is adjusted, and the bending radius of the bottom of the sewage pipe is adjusted, the blockage problem during sewage discharge of the toilet can be improved. SUMMARY

[0003] The utility model discloses a sewage structure of flush toilet to solve the technical problem of adjusting the sewage structure of the pot to improve the sewage effect. By adjusting the sewage structure of the toilet, the flushing effect and the sewage effect of the toilet are balanced, the sewage wall-hanging and the sewage blockage are reduced, the smoothness and efficiency of the toilet flushing and sewage are ensured, and the water-saving effect is achieved.

[0004] The utility model discloses a sewage structure of flush toilet, which comprises a sewage pipe connected with a pot and a sewage outlet, wherein the slope alpha of the back wall surface of the pot is not less than 93.4 degrees, and the bottom of the back wall surface of the pot is provided with an arc-shaped protrusion protruding towards the front wall surface of the pot, the radius of the arc-shaped protrusion is not less than 38mm, and the arc length is not less than 22.3mm; a bend section is arranged on the sewage pipe, the round corner radius of the bend section is not less than 9mm, the round corner arc length is not less than 18.6mm, and the height h of the horizontal tangent of the round corner vertex and the joint of the arc-shaped protrusion and the pot is not less than 45mm; the two ends of the bend section (201) are respectively connected with an inlet section and an outlet section, the inlet section is connected with the pot, and the included angle beta of the joint of the inlet section and the arc-shaped protrusion is not less than 30 degrees, and the outlet section is connected with the sewage outlet.

[0005] Due to the inclination of the rear wall of the toilet bowl is not less than 93.4°, when flushing, the water flow can flow down along the inner wall of the toilet more quickly, increasing the force and efficiency of flushing, and making the water flow more concentrated, so that it is easier to flush away larger dirt and reduce the possibility of blockage. The radius of the rear wall of the bowl connecting with the arc-shaped protrusion is not less than 38mm, and the arc length is not less than 22.3mm. The arc-shaped protrusion can guide the water flow, thereby changing the direction and path of the water flow, making the water flow directly hit the inner wall of the toilet and the sewage outlet, reducing the loss of water flow, ensuring the flushing effect, and the bottom of the bowl connecting with the communicating sewage pipe is provided with a bend section, the two ends of the bend section are respectively connected with the inlet section and the outlet section, the inlet section is connected with the bowl, and the outlet section is connected with the sewage outlet, so that the water flow flows into the sewage pipe. When the water flow flows into the sewage pipe from the bowl, the angle between the inlet section and the bowl is not less than 30°, so that the connection is more smooth, and the flow area of the water flow in the sewage pipe is contracted, so that the flow velocity of the water flow in the transition section increases, thereby quickly removing the dirt, shortening the residence time of the dirt in the sewage pipe, improving the sewage efficiency. After the water flow flows into the bend section, the fillet radius of the bend section is not less than 9mm, and the arc length of the fillet is not less than 45mm, so that the water flow can flow smoothly, reducing the blockage phenomenon, and the height h of the horizontal tangent of the top end of the fillet and the connection point of the bowl is not less than 45mm, improving the flushing effect of the water flow on the toilet, and then the water flow flows into the outlet section and flows out of the sewage outlet. While the flow velocity of the water flow in the sewage pipe increases, the water flow can improve the flushing force of the water flow on the inner wall of the sewage pipe, enhance the self-cleaning ability of the sewage pipe, ensure the smoothness of the sewage, and after the water flow carries the dirt out of the sewage pipe, the inlet section and the outlet section connected by the two ends of the bend section are inclined upward. After the toilet is flushed, water is stored on the bend section, the inlet section and the outlet section, forming a water seal, preventing the gas and odor in the sewer from flowing back to the room, and ensuring the deodorizing effect of the toilet.

[0006] Further optimize the technical solution, the inclination of the rear wall of the bowl α is 93.4°-113°.

[0007] The inclination of the rear wall of the bowl is in the range, when flushing, the water flow can flow down along the inner wall of the toilet more quickly, increasing the force and efficiency of flushing, and making the water flow more concentrated, so that it is easier to flush away larger dirt and reduce the possibility of blockage.

[0008] Further optimize the technical solution, the radius of the arc-shaped protrusion is 38mm-118mm.

[0010] Further optimization of the technical scheme, the arc length of the arc-shaped protrusion is 22.3mm-62.2mm.

[0011] When the arc length is controlled in the range, the flushing water amount and the flushing effect are balanced, and the water-saving effect is realized.

[0012] Further optimization of the technical scheme, the height h of the horizontal tangent of the junction point of the arc-shaped protrusion and the round corner vertex is 45mm-116.16mm.

[0013] When the height of the horizontal tangent of the junction point of the arc-shaped protrusion and the round corner vertex is controlled in the range, the flushing effect and the sewage effect are balanced, the flushing effect and the sewage effect are ensured, the flushing amount and the sewage are balanced, and the water-saving effect is realized.

[0014] Further optimization of the technical scheme, the included angle β of the junction point of the arc-shaped protrusion and the inlet section is 89°-30°.

[0015] When the included angle of the junction point of the arc-shaped protrusion and the inlet section is controlled in the range, the water flow is smoother, and the loss of water flow force is reduced.

[0016] Further optimization of the technical scheme, the round corner radius of the elbow section is 9mm-30mm.

[0017] When the round corner radius of the elbow section is controlled in the range, the water flow can flow smoothly, and the blocking phenomenon is reduced

[0018] Further optimization of the technical scheme, the round corner arc length of the elbow section is 18.6mm-48.7mm.

[0019] When the round corner radius of the elbow section is controlled in the range, the water flow path is balanced, and the sewage effect is ensured.

[0020] The beneficial effects of the utility model lie in:

[0021] 1, when flushing water in the closestool, the water flow can flow down along the closestool inner wall more quickly on the back wall surface of the closestool, the force and efficiency of the flushing water are increased, and the water flow is more concentrated, so that larger dirt is more easily flushed away, and the possibility of blocking is reduced;

[0022] 2, the arc-shaped protrusion connected with the bottom of the back wall surface of the closestool guides the water flow, so that the direction and path of the water flow are changed, the water flow directly hits the closestool inner wall and the sewage outlet, the flushing effect is ensured, the dead angle on the closestool is reduced, the dirt wall-hanging phenomenon is reduced, the water flow collision in the closestool and the sewage pipeline is reduced, the water flow force loss is reduced, the flushing effect is enhanced, the dirt is more easily taken away, and the sewage effect is ensured;

[0023] 3. After the water flow enters the elbow section, the low resistance coefficient of the elbow section enables the water flow to flow smoothly, reducing the blocking phenomenon, and the horizontal tangent of the vertex of the fillet on the elbow section and the junction of the arc-shaped protrusion and the bowl are controlled within a suitable height range, balancing the flushing effect and the sewage discharge effect, which can ensure both the flushing effect and the sewage discharge effect, so that the closestool has a water-saving effect;

[0024] 4.

At the same time, the increased water flow increases the scouring force of the water flow on the inner wall of the sewage pipe, thereby improving the self-cleaning ability of the sewage pipe.

DETAILED DESCRIPTION

[0030] The present utility model will be further described in detail in combination with the drawings and specific embodiments.

[0031] Please refer to the drawings Figures 1-4 A sewage discharge structure of a flushing closestool, comprising a sewage pipe 2 connected to a bowl 1 and a sewage outlet 3, wherein the slope a of the rear wall of the bowl 1 is not less than 93.4°. When flushing, the water flow can flow down the inner wall of the closestool more quickly, increasing the force and efficiency of flushing, and making the water flow more concentrated, thereby more easily flushing away larger sewage and reducing the possibility of blocking. When the slope of the rear wall of the bowl 1 is controlled to be 93.4°-113°, the flushing amount and effect are balanced, the flushing of the closestool is more water-saving, and a high-quality flushing effect is achieved.

[0032] The back wall bottom of the toilet 1 is provided with an arc-shaped protrusion 4 protruding towards the front wall of the toilet 1. After the water flow flows to the arc-shaped protrusion 4, the arc-shaped protrusion 4 guides the water flow, so that the water flow directly hits the inner wall of the toilet and the sewage outlet 3, reducing the loss of water flow impact and ensuring the flushing effect. The radius of the arc-shaped protrusion 4 is not less than 38mm, and the arc length is not less than 22.3mm. Especially when the radius and arc length of the arc-shaped protrusion 4 are controlled within the range of 38mm-118mm and 22.3mm-62.2mm, the transition of the water flow along the arc-shaped protrusion 4 is more smooth, the flushing effect is balanced, and the water flow can more accurately impact the sewage pipe 2, improving the sewage efficiency and avoiding the formation of a cleaning dead angle, which facilitates cleaning.

[0033] The sewage pipe 2 connected to the toilet 1 is provided with an elbow section 201. The two ends of the elbow section 201 are connected to an inlet section 202. The inlet section 202 is connected to the toilet 1, so that the water flow can smoothly flow into the sewage pipe 2. The included angle β between the inlet section 202 and the arc-shaped protrusion 4 is not less than 30°, so that the water flow can smoothly flow into the sewage pipe 2. When the included angle β between the inlet section 202 and the arc-shaped protrusion 4 is controlled within the range of 89°-30°, the water flow can smoothly flow into the sewage pipe 2, reducing the loss of water flow impact and ensuring smooth flow.

[0034] After the water flow flows through the inlet section 202, it enters the elbow section 201. The radius of the rounded corner 2011 of the elbow section 201 is not less than 9mm, and the arc length of the rounded corner 2011 is not less than 18.6mm. When the radius and arc length of the rounded corner 2011 of the elbow section 201 are controlled within the range of 9mm-30mm and 18.6mm-48.7mm, the water flow can smoothly flow through, reducing the phenomenon of blockage. The horizontal tangent of the vertex of the rounded corner 2011 and the height h of the junction of the arc-shaped protrusion 4 and the toilet 1 are not less than 45mm. Especially when they are controlled within the range of 45mm-116.16mm, the flushing effect of the water flow and the sewage effect of the water flow can be balanced, the flushing amount can be optimized, and a full flushing effect of the toilet can be achieved through a 3L flushing amount, achieving the water-saving effect of the toilet.

[0035] After the water flow flows through the elbow section 201, it enters the outlet section 203. The outlet section 203 is connected to the sewage outlet 3 of the toilet, so that the sewage can be discharged outward. The inlet section 202 and the outlet section 203 connected by the two ends of the elbow section 201 are both upwardly inclined. After the toilet is flushed, water is stored on the elbow section 201 and the inlet section 202 and the outlet section 203, forming a water seal, preventing the gas and odor in the sewer from flowing back into the room, and ensuring the deodorizing effect of the toilet.

[0036] The working principle of the sewage discharge structure of the flush toilet is that when the sewage in the toilet bowl 11 is flushed away by flushing water into the toilet, the inclined surface of the rear wall of the toilet bowl 1 enables the water flow to flow down along the inner wall of the toilet more quickly, increases the flushing force and efficiency, and makes the water flow more concentrated, so that larger sewage can be flushed away more easily and the possibility of blockage is reduced. The arc-shaped protrusion 4 at the bottom of the toilet bowl 1 can guide the water flow, so that the water flow directly hits the inner wall of the toilet and the sewage discharge port 3, reduces the loss of water flow, ensures the flushing effect, balances the flushing amount and flushing effect, realizes the water saving effect, and at the same time, the radian and arc length of the arc-shaped protrusion 4 avoid the formation of a sanitary dead angle and the breeding of bacteria, facilitating cleaning. After the water flow enters the sewage pipe 2 from the inlet section 202, the junction angle between the inlet section 202 and the arc-shaped protrusion 4 ensures the smoothness of the water flow, avoids water loss, and the reduction of the flow area in the sewage pipe 2 causes the water flow to accelerate after entering the inlet section 202, thereby quickly removing the sewage, shortening the residence time in the sewage pipe 2, improving the sewage efficiency, and at the same time, the accelerated water flow has strong scouring force, enhancing the self-cleaning ability of the sewage pipe 2. After the water flow enters the elbow section 201 of the sewage pipe 2, the low resistance coefficient of the elbow section 201 enables the water flow to flow smoothly, avoiding blockage. The junction point of the horizontal tangent at the top end of the upper round corner 2011 of the elbow and the arc-shaped protrusion 4 and the toilet bowl 1 is controlled at an appropriate height, so that the flushing effect and the sewage discharge effect are well balanced, which can ensure the flushing effect and the sewage discharge effect, further improving the water saving effect of the toilet. After the water flow flows through the elbow section 201, it enters the outlet section 203, and the junction of the outlet section 203 and the sewage discharge port 3 is connected, so that the water flow flows out smoothly. Since the inlet section 202 and the outlet section 203 are both upwardly inclined, water is stored on the elbow section 201 and the inlet section 202 and the outlet section 203 after flushing the toilet, forming a water seal, preventing the gas and odor in the sewer from flowing back to the room, and ensuring the deodorization effect of the toilet.
