[0025] The existing sewage pipes cannot improve the flushing and sewage discharge capacity and are prone to siphoning.
[0026] Based on the above problems, the present application proposes a sewage pipe and a toilet, which can effectively solve the above problems by setting the vertical dimension of the cross-sectional figure at the highest point of the turning section in the circumferential direction to be smaller than the horizontal dimension of the cross-sectional figure.
[0027] A sewage pipe and a toilet provided by the present application are described in detail below with reference to the accompanying drawings and embodiments.
[0028] This application provides a sewage pipe. Figures 1 to 3 , Figure 1 This is a schematic structural diagram of an embodiment of a sewage pipe of the present application; Figure 2 for Figure 1 A schematic diagram of the structure in which the sewage pipe is arranged in the toilet; Figure 3 for Figure 2 Schematic diagram of the structure along the Aa section. In some embodiments, the sewage pipe 100 includes an ascending section 10 , a turning section 20 and a descending section 30 .
[0029] Along the sewage discharge direction, the rising section 10, the turning section 20 and the descending section 30 are connected in sequence. Among them, the dimension b of the cross-sectional figure in the circumferential direction at the highest point of the turning section 20 in the vertical direction is smaller than the dimension B of the cross-sectional figure in the horizontal direction. Specifically, the sewage pipe 100 is a siphon-type sewage pipe 100, which is used to discharge liquid and can be used in swimming pools, industrial wastewater treatment, toilet sewage and other fields for sewage discharge. In this embodiment, the sewage pipe 100 is specifically used for toilet sewage discharge. Among them, the sewage inlet 51 of the rising section 10 of the sewage pipe 100 and the sewage outlet 52 of the descending section 30 are located at different heights in the vertical direction. In this embodiment, the height of the sewage inlet 51 of the rising section 10 is higher than the height of the sewage outlet 52 of the descending section 30, so that the pressure difference generated by the liquid level difference can be used to form a siphon to drive the liquid flow. Among them, the formation of the siphon requires that the highest point inside the sewage pipe 100 is also filled with liquid. In the existing sewage pipe 100, the cross-section of the bend section 20 is in the shape of a standard circle. When the pipe diameter is increased to improve the sewage discharge capacity, the vertical dimension b of the highest point of the bend section 20 will also increase, making it difficult to fill the highest point inside the sewage pipe 100 with liquid, increasing the difficulty of siphoning. If the pipe diameter is reduced to make it easier for the sewage pipe 100 to form a siphon, the sewage discharge capacity of the sewage pipe 100 is reduced; it is difficult to simultaneously ensure the improvement of sewage discharge capacity and the reduction of the difficulty of siphoning. In this embodiment, the cross-sectional figure in the circumferential direction at the highest point of the turning section 20 is a non-standard circle, and its dimension b in the vertical direction is smaller than the dimension B in the horizontal direction. By increasing the dimension B in the horizontal direction, the cross-sectional area of the sewage pipe 100 is increased, thereby improving the sewage discharge capacity of the sewage pipe 100. On the other hand, while increasing the dimension B in the horizontal direction while keeping the dimension b in the vertical direction unchanged or reducing the dimension b in the vertical direction, the area of the cross-section at the highest point of the turning section 20 is increased while the highest point inside the sewage pipe 100 remains unchanged or decreases, thereby making it easier for the liquid to fill the sewage pipe 100 and reducing the difficulty of the siphon phenomenon.
[0030] Different from the prior art, the vertical dimension b of the cross-sectional figure of the highest point of the bend section 20 of the sewage pipe 100 of the present application is smaller than the horizontal dimension B of the cross-sectional figure. The above can increase the cross-sectional area of the highest point of the sewage pipe 100 while reducing the height of the highest point inside the sewage pipe 100, which can improve the flushing and sewage discharge capacity of the sewage pipe 100 and easily generate the siphon phenomenon.
[0031] In some embodiments, the cross-sectional figure is an oblate circle surrounded by arcs. Specifically, the dimensions of the oblate circle in two vertical directions are different. In some embodiments, the cross-sectional figure in the circumferential direction at the highest point of the turning section 20 can also be an ellipse, a rectangle or other irregular reasonable figures, as long as the dimension b of the cross-sectional figure in the circumferential direction at the highest point of the turning section 20 in the vertical direction is smaller than the dimension B of the cross-sectional figure in the horizontal direction, without specific limitation.
[0032] In some embodiments, the sewage pipe 100 further includes a trap section 40, which is arranged at the other end of the ascending section 10 connected to the turning section 20, and the trap section 40 is the sewage inlet 51 of the sewage pipe 100. Specifically, the sewage pipe 100 is used in a toilet, and the trap section 40 of the sewage pipe 100 is used to accumulate liquid of a certain height to form a water seal to isolate the gas, which can effectively prevent harmful gases, odors, and small animals such as insects and mice in the sewer connected to one end of the descending section 30 of the sewage pipe 100 from entering the room. In addition, the trap section 40 also plays a role in preventing backflow. In this embodiment, the trap section 40 accumulates a certain height of liquid to ensure that the liquid level can completely cover the sewage inlet 51 of the sewage pipe 100 to form a siphon phenomenon.
[0033] The cross-sectional figures of the trap section 40, the ascending section 10, and the descending section 30 in the circumferential direction are oval or circular. Specifically, in this embodiment, except for the oval cross-sectional figure of the highest part of the bend section 20 in the circumferential direction of the sewage pipe 100, the cross-sectional figures of other regions in the circumferential direction of the sewage pipe 100 are all standard circles. In some other embodiments, the cross-sectional figures of each region in the circumferential direction of the sewage pipe 100 can also be oval.
[0034] In some embodiments, the descending section 30 is arranged with multiple bends. Specifically, the descending section 30 is arranged with multiple bends, which can slow down the discharge speed of the siphoned liquid, better absorb the impact sound and vibration of the liquid, and reduce the noise during sewage discharge. On the other hand, the descending section 30 is arranged with multiple bends to slow down the liquid flow rate, which helps to intercept larger solid matter, prevent the solid matter from being directly flushed into the sewer from the descending section 30, and avoid clogging of the sewer.
[0035] Further, in a preferred embodiment, the descending section 30 includes at least a first descending portion 31, a second descending portion 32, and a third descending portion 33 connected in sequence along the sewage discharge direction. Among them, the inclination angle of the first descending portion 31 is greater than the inclination angle of the second descending portion 32, and the inclination angle of the second descending portion 32 is less than the inclination angle of the third descending portion 33. The first descending portion 31 connects the turning section 20. The descending section 30 also includes a fourth descending portion 34 and a fifth descending portion 35 connected in sequence along the sewage discharge direction, the fourth descending portion 34 connects the third descending portion 33, the inclination angle of the fourth descending portion 34 is less than the inclination angle of the third descending portion 33, and the inclination angle of the fifth descending portion 35 is greater than the inclination angle of the fourth descending portion 34. Specifically, the descending section 30 of the above-mentioned sewage discharge pipe 100 changes its inclination angle continuously along the sewage discharge direction, which can effectively slow down the discharge speed of the liquid and effectively reduce noise. In this embodiment, the descending section 30 is composed of five sections with changing inclination angles. In some other embodiments, the descending section 30 can also be composed of three sections, four sections, six sections, and other reasonable sections, which are not specifically limited.
[0036] In a preferred embodiment, the fifth descending portion 35 is vertically arranged, and the fifth descending portion 35 is the sewage outlet 52 of the sewage pipe 100. The fourth descending portion 34 is horizontally arranged. Specifically, the fifth descending portion 35 is used to connect to the sewer, wherein the fourth descending portion 34 is horizontally arranged, and the advantage of the fifth descending portion 35 being vertically arranged is that when the liquid flows through the fourth descending portion 34, the flow velocity of the liquid in the vertical direction is reduced to zero, thereby avoiding the liquid from flowing into the sewer from the fifth descending portion 35 to generate a large impact force.
[0037] In some embodiments, the rising section 10 is arranged in a straight line. Specifically, the rising section 10 is in a straight line to avoid the liquid from being blocked in the rising section 10 when flowing, so that the liquid can better fill the highest point of the sewage pipe 100 and more easily produce a siphon effect.
[0038] In some embodiments, the trap section 40, the rising section 10, the turning section 20 and the descending section 30 are integrally formed, so that the sewage pipe 100 has fewer connecting structures, the sewage pipe 100 is not prone to water leakage, and the sewage pipe 100 has better structural stability.
[0039] Different from the prior art, the vertical dimension b of the cross-sectional figure of the highest point of the bend section 20 of the sewage pipe 100 of the present application is smaller than the horizontal dimension B of the cross-sectional figure. The above can increase the cross-sectional area of the highest point of the sewage pipe 100 while reducing the height of the highest point inside the sewage pipe 100, which can improve the flushing and sewage discharge capacity of the sewage pipe 100 and easily generate the siphon phenomenon.
[0040] Correspondingly, the present application also proposes a toilet, which includes a toilet chamber and a sewage pipe, wherein the sewage pipe is connected to the toilet chamber, and the sewage pipe is the sewage pipe described in the above embodiment.
[0041] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent principle transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
