Detailed Description

In addition, from the viewpoint of fluid flow analysis, where the fluid encounters a right angle turn during the flow process, the right angle position may create turbulence, thereby changing and affecting the overall flow velocity. The influence caused in the application of the sewage discharge pipe is reflected in that the sewage discharge efficiency and the sewage discharge effect of sewage discharge flow are influenced; in addition, in the sewage disposal process, due to the existence of the opening corners, the condition that the corners are hung with sewage is possibly generated in the sewage disposal process.

The sewage pipe, the sewage system and the closestool provided by the embodiment of the application can solve the problems.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1 to 4, one embodiment of the present application provides a soil pipe 2 including: a sewage intake section 21 and a sewage discharge section 22.

Wherein, the sewage inlet pipe section 21 is rotatably connected with the sewage discharging box 1 of the closestool, and the sewage inlet pipe section 21 is provided with a sewage inlet 211.

The sewage draining pipe section 22 is connected with the sewage inlet pipe section 21 and is arranged in a bending mode relative to the sewage inlet pipe section 21. One end of the sewage discharge pipe section 22, which is far away from the sewage inlet pipe section 21, is provided with a sewage discharge port 221, and the area of the sewage discharge port 221 is larger than that of the sewage inlet 211.

The sewage draining pipe 2 provided by the embodiment of the application comprises a sewage inlet pipe section 21 and a sewage draining pipe section 22. The sewage inlet pipe section 21 is provided with a sewage inlet 211 for the sewage in the basin cavity 202 of the toilet seat body 200 to enter. The sewage discharge pipe section 22 is provided with a sewage discharge port 221 for discharging the sewage in the sewage discharge pipe 2. The sewage discharge pipe section 22 is connected with the sewage inlet pipe section 21 and is bent relative to the sewage inlet pipe section 21, so that a height difference is generated between the position of the sewage discharge port 221 and the position of the sewage inlet 211, and sewage can be conveniently discharged under the action of gravity.

Because the sewage inlet pipe section 21 can be rotatably connected with the sewage discharging box 1 of the toilet, the sewage discharging pipe section 22 can be driven to rotate from top to bottom in the sewage discharging process so as to discharge the sewage in the sewage discharging pipe 2 into the sewage discharging box 1 by utilizing gravitational potential energy, and the sewage can enter the shifter through the sewage outlet 112 of the sewage discharging box 1 and then enter an external sewage discharging channel, as shown in fig. 8 and 9.

Compare in the scheme that advances dirty mouthful 211 and drain 221 diameter equal among the prior art, this scheme sets up the area that the area of drain 221 is greater than into dirty mouthful 211, has increased the area of drain 221 in other words, therefore is favorable to improving blowdown efficiency, reduces the probability that the filth hangs at drain 221.

In an exemplary embodiment, the intake pipe section 21 is a mirror-symmetrical structure. The symmetry plane S1 of the sewage intake section 21 extends in the extension direction of the sewage discharge section 22.

In one example, the dirt inlet 211 is provided in a circular shape. The drain opening 221 is provided in a shape of a rectangle, as shown in fig. 2.

The sewage inlet pipe section 21 adopts a mirror symmetry structure, and the sewage inlet 211 is round, so that the structure is regular, and the processing and forming are convenient; it is also advantageous to simplify the sealing structure between the waste pipe section 21 and the waste box 1.

During the rotary blowdown process, the initial position of the blowdown section 22 is generally vertical as shown in fig. 8, i.e., with the blowdown outlet 221 facing horizontally upward. Thus, the extension direction of the waste pipe section 22 in this state is the vertical direction. Since the symmetry plane of the sewage inlet section 21 extends along the extension direction of the sewage pipe section 22, the symmetry plane of the sewage inlet section 21 is the vertical plane of the sewage inlet section 21 when the sewage pipe 2 is in the initial position.

The sewage draining outlet 221 is specially-shaped, and the sewage draining outlet 221 can be enabled to be properly expanded outwards only on the basis of the existing circular shape, so that the area of the sewage draining outlet 221 can be larger than that of the sewage inlet 211. In the design process, the tail end of the sewage discharge pipe section 22 is only required to be properly expanded and deformed outwards, so that the improvement is facilitated on the basis of the existing sewage discharge pipe 2, and the area of the sewage discharge port 221 is increased under the condition that the whole volume of the sewage discharge pipe 2 is basically unchanged, so that the sewage discharge efficiency and the sewage discharge effect are improved.

In an exemplary embodiment, the waste pipe section 22 is divided into a dump portion 222 and a non-dump portion 223, as shown in fig. 4, with the plane of symmetry of the waste pipe section 21 being the interface 212. The soil pipe 2 is rotated toward the side where the dumping part 222 is located during the rotation.

Wherein, the area of the dumping part 222 near the sewage draining exit 221 is provided with a diversion inclined plane 2221, as shown in fig. 4. The guide slope 2221 extends obliquely in a direction away from the interface surface 212 in a direction toward the soil discharge opening 221.

Because the sewage pipe 2 only needs to rotate to one side in the rotating process, namely to the side where the dumping part 222 is located, the sewage can flow to the sewage outlet 221 along the inner wall surface of the dumping part 222 as far as possible under the action of gravity and is discharged. Therefore, the area of the dumping part 222 close to the sewage outlet 221 is provided with the flow guiding inclined plane 2221, which is equivalent to that an inclined port is added at the opening of the traditional regular cylindrical structure, so that the sewage can be guided well, the flow rate of the sewage can be improved, the sewage can be discharged from the sewage outlet 221 quickly and smoothly, and the sewage discharge efficiency can be improved.

And, the setting of direction inclined plane for drain 221 forms special-shaped opening, and is bigger than traditional circular opening area, also is favorable to promoting the blowdown flow of drain 221, and then promotes blowdown efficiency.

The increase of the flow rate and the flow rate of the sewage discharge can reduce the probability of the sewage hanging at the sewage discharge port 221, thereby improving the sewage discharge effect.

In an exemplary embodiment, the angle of inclination of the deflector ramp 2221 with respect to the interface surface 212 is in the range of 10 ° to 20 °, as shown in fig. 5.

The inclination angle of the diversion inclined plane 2221 relative to the interface 212 is limited within the range of 10 degrees to 20 degrees, so that the problems that the drainage pipe section 22 occupies too much space due to the overlarge inclination angle of the diversion inclined plane 2221, the volume of the drainage box 1 is increased due to the increase of the occupied space of the drainage pipe section 22, and the miniaturization of the drainage box 1 is not facilitated are avoided.

As shown in fig. 5, in a comparative example, the inclination angle of the guide slope 2221 is increased to 30 °, the width of the soil discharge opening 221 in the left-right direction is increased by a 1. In another comparative example, the inclination angle of the guide slope 2221 is increased to 45 °, the width of the soil discharge opening 221 in the left-right direction is increased by a 2. Thus, the space occupied by the soil pipe 2 is increased. As shown in fig. 12, when the sewage pipes 2 rotate by the same angle to reach the sewage draining position, the volume of the sewage draining box 1 needs to be increased correspondingly due to the increase of the inclination angle of the air guiding inclined plane 2221, which is not favorable for the miniaturization of the sewage draining box 1.

Therefore, the inclined angle of the diversion inclined plane 2221 relative to the interface 212 is limited within the range of 10 degrees to 20 degrees (such as 10 degrees, 13 degrees, 15 degrees, 18 degrees, 20 degrees and the like) by the scheme, so that the sewage discharge efficiency and the sewage discharge effect of the sewage discharge pipe 2 can be improved on the basis of small volume change, the miniaturization of the sewage discharge box 1 is also facilitated, and the flexibility and the adaptability of the sewage discharge system 100 can be improved.

In one exemplary embodiment, the waste pipe section 22 includes a straight pipe section 224 and a contoured pipe section 225, as shown in FIG. 1. The straight pipe section 224 is connected to the dirty pipe section 21. The special-shaped pipe section 225 is connected with the straight pipe section 224, and a flow guiding inclined plane 2221 is arranged at the position, close to the sewage outlet 221, of the special-shaped pipe section 225.

The straight pipe section 224 may be generally cylindrical to facilitate smooth interface with the dirty pipe section 21. And the special pipe section 225 is provided with a flow guide inclined surface 2221, so that the sewage discharge efficiency and the sewage discharge effect can be improved.

And design like this for water conservancy diversion inclined plane 2221 is only located the terminal part of blowdown pipe section 22, and the length of water conservancy diversion inclined plane 2221 is shorter relatively, therefore the volume of blowdown pipe section 22 is less compared with regular cylindrical change, so be favorable to blow off pipe 2 to promote blowdown efficiency and blowdown effect on the basis that its volume change is little, also be favorable to the miniaturization of blowdown box 1, and then be favorable to promoting the flexibility and the suitability of blowdown system 100.

In an exemplary embodiment, the waste pipe section 22 is a mirror-symmetrical structure. The symmetry plane S2 of the waste pipe section 22 is perpendicular to the symmetry plane S1 of the waste pipe section 21, as shown in fig. 2.

As shown in fig. 2, the waste pipe section 22 is mirror-symmetrical in the front-rear direction with respect to the direction in the drawing, and the symmetrical surface S2 of the waste pipe section 22 extends in the up-down direction and the left-right direction. The sewage intake pipe section 21 is mirror-symmetrical in the left-right direction, and a symmetrical surface S1 of the sewage intake pipe section 21 extends in the up-down direction and the front-rear direction. Thus, the symmetry plane S2 of the waste pipe section 22 is perpendicular to the symmetry plane of the waste pipe section 21S 1.

Thus, the waste pipe section 22 is also relatively regular in shape and easy to machine. In addition, the force of the sewage discharge pipe section 22 is balanced, and the stability of the sewage discharge pipe 2 in the rotating process is improved.

In an exemplary embodiment, the central axis of the sewage inlet 211 intersects the central axis of the sewage outlet 221 in a plane of symmetry of the sewage inlet section 21, and the angle θ is less than 90 °, as shown in fig. 3.

Thus, an acute angle is formed between the sewage inlet direction of the sewage inlet 211 and the sewage discharge direction of the sewage outlet 221, instead of the right angle of the conventional right angle elbow.

Since the sewage drain 2 is in the initial position, as shown in fig. 8, 10 and 13, the sewage pipe section 22 is in the vertical state, and thus the central axis of the sewage drain 221 also extends in the vertical direction. Since an acute angle is formed between the sewage inlet direction of the sewage inlet 211 and the sewage discharge direction of the sewage outlet 221, not a right angle of the conventional right angle elbow, the central axis of the sewage inlet 211 extends obliquely downward, not in a horizontal direction. Therefore, the sewage in the basin cavity 202 can rapidly enter the sewage discharge pipe 2 under the action of gravity, and the flow guide of the sewage can be facilitated, so that the sewage discharge efficiency and the sewage discharge effect can be further improved.

And, when the blow-off pipe 2 rotates to the blow-off position, as shown in fig. 9, 11 and 14, the blow-off pipe 2 forms a dual-inclination blow-off slide way similar to a rotary slide, and has two slopes, the sewage in the basin cavity 202 firstly enters the first slope (i.e. the sewage inlet pipe section 21) through the sewage inlet 211, and then turns to the second slope (i.e. the blow-off pipe section 22) to be discharged quickly, thereby ensuring that the toilet can blow off sewage better and faster.

In an exemplary embodiment, the angle θ between the central axis of the sewage inlet 211 and the central axis of the sewage inlet 221 is in the range of 75 ° to 85 °, such as 75 °, 80 °, 85 °, on a plane of symmetry of the sewage inlet section 21.

This is also advantageous to prevent the sewage from turning sharply when the sewage is rotated from the sewage inlet pipe section 21 to the sewage discharge pipe section 22, so that the sewage discharge efficiency and the sewage discharge effect are better.

In an exemplary embodiment, the waste pipe section 22 is in circular arc transition connection with the waste pipe section 21, as shown in fig. 3.

In an exemplary embodiment, the soil pipe 2 further includes: the connecting portion 24 is connected to the sewage inlet pipe section 21, the connecting portion 24 is connected to the driving device 3 for driving the sewage discharge pipe 2 to rotate, and the central axis of the connecting portion 24 coincides with the central axis of the sewage discharge outlet 221, as shown in fig. 3.

Like this, after the assembly is accomplished, drive arrangement 3 drives connecting portion 24 and rotates, and then can drive the relative blowdown box 1 of blow off pipe 2 whole and rotate around the central axis of dirty mouthful 211 of advancing.

In an exemplary embodiment, the minimum distance H between the waste outlet 221 and the waste inlet 211 is greater than or equal to 50mm, as shown in fig. 3.

When the sewage draining pipe 2 is at the initial sewage draining position, the position of the lowest point of the sewage draining opening 221 determines the upper limit of a water seal cover in the toilet, and the position of the highest point of the sewage inlet 211 determines the lower limit of the water seal in the toilet. And the height difference between the position of the lowest point of the drain outlet 221 and the position of the highest point of the drain outlet 221 is equal to the minimum distance between the drain outlet 221 and the drain inlet 211. Therefore, the minimum distance between the sewage outlet 221 and the sewage inlet 211 is limited to be greater than or equal to 50mm, and the water seal height H0 (or the water seal depth) in the toilet can be ensured to be not less than 50mm as shown in FIG. 13 so as to meet the national standard requirement.

In an exemplary embodiment, the diameter d of the dirt intake 211 is in the range of 55mm to 65mm, as shown in FIG. 3.

The pipe diameter of traditional blow off pipe 2 is generally in 45mm to 50 mm's within range, and the diameter of entering dirty mouthful 211 equals blow off pipe 2's pipe diameter, also is in 45mm to 50 mm's within range. And this scheme will be discharged dirty mouthful 211 diameter d and inject in 55mm to 65 mm's within range (like 55mm, 60mm, 65mm etc.), and dirty mouthful 211 area of advancing obviously increases, and the area of drain 221 is greater than the area of dirty mouthful 211, therefore the pipe diameter increase of whole blow off pipe 2 can promote the blowdown performance of scouring away the pipeline better, also is favorable to practicing thrift blowdown water, realizes the purpose of environmental protection and water conservation. The volume of the sewage discharge port 221 is not changed greatly, so that various factors such as structure, volume, environmental protection and the like are considered.

In an exemplary embodiment, the length of the sewage drain 2 is in the range of 130mm to 140mm, such as 130mm, 132mm, 135mm, 138mm, 140mm, etc.

Most of the length of the traditional siphon pipe is more than 700mm, and the pipe of the sewage discharge pipe 2 in the scheme is obviously shortened. The big pipe diameter cooperation short tube way can make the blowdown performance of blow off pipe 2 of this application embodiment more reliable and more reliable, is difficult for taking place to block up more.

In an exemplary embodiment, the end of the waste pipe section 21 remote from the waste pipe section 22 is further provided with a sealing boss 23 for mounting the sealing member 14, as shown in fig. 1, 2 and 3. The sealing boss 23 is annular, and the inner diameter of the sealing boss 23 is larger than the diameter of the dirt inlet 211.

The arrangement of the sealing boss 23 is convenient for the installation of the sealing element 14, is beneficial to realizing the sealing fit among the sewage discharge pipe 2, the sewage discharge box 1 and the toilet bowl 202, and prevents the leakage of sewage.

In an exemplary embodiment, the outer wall surface of the sealing boss 23 adjacent to the waste discharge opening 221 is connected to the outer wall surface of the waste discharge pipe section 22, as shown in fig. 3.

Thus, the length of the waste pipe section 21 is very small, the portion of the waste pipe section 21 connected to the non-pouring portion 223 of the waste pipe section 22 is even negligible, and the portion connected to the pouring portion 222 of the waste pipe section 22 is substantially circular arc-shaped. Thus, the dirty section 21 generally corresponds to a transition joint. Thus being beneficial to shortening the pipeline length of the sewage discharge pipe 2 and further being beneficial to improving the sewage discharge performance of the sewage discharge pipe 2.

As shown in fig. 6, the present embodiment also provides a soil exhaust system 100, including: a waste box 1, a waste pipe 2 as in any of the previous embodiments and a drive means 3.

The sewage discharge pipe 2 is rotatably connected with the sewage discharge box 1. The driving device 3 is connected with the sewage discharge pipe 2 and is used for driving the sewage discharge pipe 2 to rotate relative to the sewage discharge box 1.

In an exemplary embodiment, the waste box 1 includes a box body 11 and a box cover 12, as shown in fig. 6. The cartridge body 11 is provided with a rotation attachment hole 111 as shown in fig. 6. The box cover 12 is connected with the box body 11 in a covering manner. A sealing ring 13 is arranged between the box cover 12 and the box body 11, and as shown in figure 6, a sealing element 14 is arranged between the sewage discharge pipe 2 and the sewage discharge box 1. The box main body 11 is provided with a connection hole 121, and the soil discharge pipe 2 is provided with a connection part 24. The driving means 3 is connected to the connecting portion 24 through a connecting hole 121 for driving the soil pipe 2 to rotate. The drive means 3 may be a motor.

The sewage disposal principle of the sewage disposal system 100 is as follows (as shown in fig. 8 to 9):

when the toilet seat body 200 is rotated to discharge sewage, sewage in the basin cavity 202 enters the sewage discharge pipe 2, the sewage discharge pipe 2 is driven by the driving device 3 to rotate rightwards by 100 degrees to 120 degrees from an initial position (namely the position that the sewage discharge port 221 faces to the right upper side, as shown in fig. 8 and 13) to reach a sewage discharge position (as shown in fig. 9 and 14), and the sewage is discharged from the sewage discharge port 221 and is discharged through the sewage outlet 112 of the sewage discharge box 1.

After the sewage discharging action is finished, the sewage discharged through the sewage discharging pipe 2 flows into the shifter through the sewage inlet of the sewage discharging box 1 and then is led into an external sewage discharging channel, and a sealing ring 13 is arranged between the shifter and the sewage discharging box 1. And the sewage draining pipe 2 is reset to the initial position (as shown in figure 10) under the driving of the driving device 3 and is applied again when the sewage draining function is carried out next time.
