[0003] At present, the siphon principle is widely used as the mainstream toilet sewage discharge. In order to form a siphon phenomenon and discharge the sewage smoothly, the existing wall-mounted toilet needs to bend the sewage pipe inside the toilet body, i.e., the ceramic body of the wall-mounted toilet for many times, resulting in the total length and total height of the sewage pipe inside the wall-mounted toilet needing to be increased to ensure that a siphon is formed inside the toilet for sewage discharge. In order to accommodate the sewage pipe that is bent many times, the structure of the existing wall-mounted toilet is large in overall volume, resulting in a large space occupation; and, since the sewage pipe is bent many times inside the toilet body, the sewage travels a long distance in the sewage pipe, which leads to poor sewage discharge efficiency.

[0033] Embodiment 1

[0034] In order to solve the problem that the toilet in the prior art has a large overall volume and poor sewage discharge efficiency, this embodiment provides a sewage pipe, which is arranged outside the toilet and is used to communicate with the liquid outlet end of the toilet body, and the sewage pipe cooperates with the toilet to form a siphon sewage discharge phenomenon. The structural setting of the sewage pipe in this embodiment can achieve siphon sewage discharge in cooperation with the flow channel inside the toilet, and can avoid setting a structural setting of multiple bends in the flow channel inside the toilet, which not only solves the problem that the toilet in the prior art has a large overall volume and occupies a large space; at the same time, it simplifies the flow channel setting inside the toilet, reduces the travel of sewage in the flow channel inside the toilet, and is conducive to improving sewage discharge efficiency.

[0035] It can be understood that the sewage pipe in this embodiment is arranged outside the toilet and is used to communicate with the liquid outlet end of the toilet body. The sewage pipe cooperates with the internal drainage channel of the toilet body to form a siphon phenomenon. The sewage pipe is arranged outside the toilet body as a part of the siphon pipeline, thereby reducing the structure of the internal drainage channel of the toilet body and the distance of the liquid flow, improving the sewage discharge efficiency, and reducing the volume of the toilet body.

[0036] like Figures 1 to 3As shown, at least a portion of the sewage pipe is bent and formed into a bent pipe section 210, the water inlet end and the water outlet end of the bent pipe section 210 are staggered in the horizontal direction, and the bent pipe section 210 is surrounded by a baffle portion and a bent portion. At least a portion of the pipe wall of the baffle portion is configured as a baffle structure 211 that deforms toward one side of the pipe. The baffle structure 211 and the bent portion have different curvatures, and the inner wall surface of the baffle structure 211 is arranged relative to the water inlet end to slow down the water flow passing through the bent pipe section 210.

[0037] Specifically, the bent pipe section 210 of the sewage pipe in this embodiment adopts staggered water inlet and outlet ends, and cooperates with the setting of the baffle structure 211, which is conducive to the rapid filling of the internal liquid of the pipe body between the bent pipe section 210 and the toilet body, forming the required height difference for the siphon phenomenon, so as to ensure the stability and rapid progress of the siphon phenomenon and improve the efficiency of siphon sewage discharge.

[0038] Among them, the setting of the baffle structure 211 is conducive to hindering the flow of liquid, so that the liquid can quickly fill the tube body between the bent tube section 210 and the toilet body to form the height difference required for the siphon phenomenon; at the same time, due to the setting of the baffle structure 211, the liquid can fill the tube body between the bent tube section 210 and the toilet body, which can prevent gas from entering this part of the tube body, thereby avoiding the problem of reduced height difference leading to poor siphon effect.

[0039] Furthermore, the inner wall surface of the baffle structure 211 is arranged opposite to the water inlet end, which is conducive to hindering the liquid entering the water inlet end, thereby hindering the flow of liquid at the bent pipe section 210.

[0040] Furthermore, if Figure 1 and Figure 2 As shown, the bending portion in this embodiment is formed as an arc surface structure, and the curvature of the baffle structure 211 is different from the curvature of the bending portion, so as to form a special-shaped structure in which the diameter is first large and then small inside the bent pipe section 210, wherein the diameter of the pipe body at the upstream position of the baffle structure 211 gradually increases along the direction of liquid flow, which is conducive to storing liquid and thus improving the siphon effect.

[0041] Specifically, the baffle portion at least includes a straight tube arm and a baffle structure 211 that are connected in the vertical direction, and the straight tube arm is arranged upstream of the baffle structure 211 .

[0042] Furthermore, the straight tube arm and the bent arm segment of the bent portion are arranged relatively to each other in the horizontal direction, and the diameter of the tube body enclosed between the two gradually increases; the baffle structure 211 and the bent arm segment of the bent portion are arranged relatively to each other in the horizontal direction, and the diameter of the tube body enclosed between the two gradually decreases.

[0043] The curvature radius of the bent arm section of the bent portion remains unchanged, and the bent arm section of the bent portion cooperates with the straight tube arm and the baffle structure to form the tube body of the bent tube section 210. Along the direction of liquid flow, the tube diameter between the baffle structure 211 and the bent portion is reduced, so that the baffle structure 211 can hinder the flow of liquid, making it convenient for the liquid to fill the upstream of the baffle structure 211, so as to form a siphon phenomenon.

[0044] In this embodiment, when the liquid flows inside the tube body formed by the baffle structure 211 with different curvatures and the bent arm segments of the bent part, the inner wall surface of the baffle structure 211 arranged opposite to the water inlet end blocks the liquid flow, and the tube diameter in this area gradually decreases, further blocking the liquid flow and facilitating the formation of a siphon phenomenon. Compared with the regular tube body bending structure in the prior art, the baffle structure 211 of the present application not only blocks the liquid flow, but also has the effect of changing the tube diameter and draining.

[0045] Furthermore, the inner wall surface of the baffle structure 211 is formed into an inclined structure that is set at an angle to the horizontal direction. The inclined structure is advantageous in achieving a certain guiding effect while blocking the liquid, thereby avoiding the phenomenon of liquid rebound causing liquid swirl.

[0046] In this embodiment, if Figures 1 to 3 As shown, the angle A between the inclined surface structure and the horizontal direction satisfies 10°≤A≤45°. When the angle A between the inclined surface structure and the horizontal direction satisfies 10°≤A≤45°, it is beneficial to improve the siphon efficiency; when the angle A is less than 10°, it will cause the liquid to rebound and the liquid to swirl; when the angle A is greater than 45°, the effect of blocking the liquid is poor and is not conducive to the generation of siphon, and the siphon effect is inefficient.

[0047] Specifically, the angle A may be any one of 10°, 15°, 20°, 25°, 30°, 35°, 40°, and 45°.

[0048] Furthermore, along the radial direction of the water inlet end of the bent pipe section 210, the extension length L of the baffle structure 211 satisfies 0.5D≤L≤D, where D is the diameter of the opening of the water inlet end of the bent pipe section 210, and it should be noted that D is the inner diameter of the opening of the water inlet end of the bent pipe section 210. When the extension length L of the baffle structure 211 is less than 0.5D, it does not have the effect of blocking the liquid; when the extension length L of the baffle structure 211 is greater than D, the liquid flow rate slows down and the siphon effect becomes weak.

[0049] It should be noted that, in the present embodiment, the radial direction of the water inlet end of the bent pipe section 210 is the horizontal direction, that is, the extension length of the baffle structure 211 along the horizontal direction is L.

[0050] In this embodiment, the sewage pipe includes a first tube body 10 and a second tube body 20 which are connected to each other. Along the flow direction of the liquid, the second tube body 20 is arranged downstream of the first tube body 10. The liquid inlet of the first tube body 10 is used to connect with the liquid outlet end of the toilet body, and the bent pipe section 210 is arranged on the second tube body 20.

[0051] The first tube body 10 and the second tube body 20 may be detachably connected or integrally formed. When the first tube body 10 and the second tube body 20 are detachably connected, they may be connected by snap-fitting or by fasteners.

[0052] Furthermore, the arrangement of the bent tube section 210 on the second tube body 20 enables the first tube body 10 to be filled with liquid.

[0053] Furthermore, along the flow direction of the liquid, the bent pipe section 210 is arranged on the end of the second tube body 20 close to the first tube body 10. The bent pipe section 210 is arranged on the end of the second tube body 20 close to the first tube body 10 to facilitate the liquid to fill the first tube body 10 when the siphon phenomenon occurs, so as to ensure the height difference of the liquid generated at the siphon site.

[0054] Furthermore, one end of the second tube body 20 away from the first tube body 10 is connected to a liquid collection structure or a sewer pipe to discharge waste to the outside of the toilet device.

[0055] like Figures 1 to 3 As shown, the opening directions of the liquid inlet and the liquid outlet of the first tube body 10 are arranged at an angle, and the first tube body 10 is formed into a corner structure.

[0056] Specifically, the setting of the corner structure is conducive to increasing the water filling speed inside the first tube body 10, thereby increasing the efficiency of siphon generation, and also facilitates the connection between the first tube body 10 and the toilet body and the second tube body 20.

[0057] Preferably, the opening direction of the liquid inlet of the first tube body 10 is perpendicular to the opening direction of the liquid outlet of the first tube body 10, the liquid inlet is arranged in the horizontal direction, and the liquid outlet is arranged in the vertical direction.

[0058] Furthermore, the angle B between the tangent direction of the corner structure and the opening direction of the liquid inlet of the first tube body 10 satisfies 10°≤B≤30°, at which time the efficiency of siphon formation is the highest and the stability of liquid flow can be guaranteed.

[0059] In this embodiment, the first tube body 10 has a liquid inlet pipe section 110, a flow pipe section 120 and a liquid outlet pipe section 130 which are arranged in sequence. The liquid inlet pipe section 110 is connected to the liquid outlet end of the toilet body, and the liquid outlet pipe section 130 is connected to the second tube body 20. Along the radial direction of the first tube body 10, the cross-sectional areas of the liquid inlet pipe section 110 and the liquid outlet pipe section 130 are smaller than the cross-sectional area of ​​the flow pipe section 120.

[0060] Among them, a variable diameter structure design with a small diameter inlet pipe section 110, a large diameter flow pipe section 120, and a small diameter liquid outlet pipe section 130 is adopted, which facilitates the rapid filling of the liquid inside the liquid inlet pipe section 110 to generate a siphon; there is more water potential energy inside the flow pipe section 120 to increase the siphon effect; and the diameter of the liquid outlet pipe section 130 is convenient to keep the first tube body 10 filled with liquid to ensure the siphon effect.

[0061] Furthermore, the cross-sectional area S1 of the liquid inlet pipe section 110 satisfies 1320 mm 2 ≤S1≤2000mm 2 .

[0062] Furthermore, the cross-sectional area S2 of the flow pipe section 120 satisfies 1700 mm 2 ≤S2≤2800mm 2 .

[0063] Furthermore, the cross-sectional area S3 of the liquid outlet pipe section 130 satisfies 1320 mm 2 ≤S3≤2000mm 2 .

[0064] It should be noted that the cross-sectional area of ​​the liquid inlet pipe section 110 may be equal to or different from the cross-sectional area of ​​the liquid outlet pipe section 130 , and can be adaptively set according to the actual situation.

[0065] Furthermore, in this embodiment, the first tube body 10 is a C-shaped structure.

[0066] In this embodiment, the shape of the opening of the first tube body 10 is circular or elliptical, which can be set as needed.

[0069] The toilet body is installed on the surface to be installed, the outer shell of the toilet body is a ceramic body, and the surface to be installed is the ground.

[0070] Furthermore, a drainage channel is provided inside the toilet body so that the drainage channel cooperates with the sewage pipe to form a siphon.

[0071] Furthermore, along the height direction of the toilet body, the lowest point of the water level inside the drainage channel is flush with the baffle structure of the sewage pipe or is located above the baffle structure. Figure 4 As shown, along the height direction of the toilet body, the distance H between the lowest point of the water level inside the drainage channel and the baffle structure 211 of the sewage pipe satisfies: H ≥ 0. The interior of the pipe body upstream of the baffle structure 211 is filled with liquid to form a full pipe state, thereby ensuring that the water level has a height difference at the lowest point inside the drainage channel, thereby ensuring the siphon effect.

[0072] In this embodiment, the toilet device also includes a bracket and a water tank, at least a portion of the first tube body 10 of the sewage pipe is fixed on the bracket, the water tank is arranged on the bracket, and the toilet body has a water inlet, the water tank and the water inlet of the toilet body.

[0073] The water inlet of the toilet body is arranged above the liquid outlet end of the toilet body, and the bracket is used to fix the water tank and the first tube body 10.

[0074] In this embodiment, the first tube body 10 is fixed to the bracket through a fixed cover, and is connected to the water outlet of the toilet body through a straight tube and a sealing ring. The bracket can be an iron frame or a bracket of other materials. Specifically, one end of the straight tube is connected to the first tube body 10, and the other end of the straight tube is connected to the water outlet of the toilet body.
