Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a curved pipe structure and a toilet. Background Art

[0002] Most existing toilets use a jet siphon system for waste removal. According to current national standards, the diameter of a toilet's elbow must be at least 41mm. The diameter determines the strength of the siphon; smaller diameters increase the siphon force but also increase the risk of blockage.

[0003] While prior technologies pursue high siphoning power, they generally ignore the problem of elbow clogging. When consumers clog the toilet due to excessive waste, they are forced to use a plunger, which degrades the user experience. However, research on anti-clogging toilet elbow structures is currently limited.

[0004] Therefore, there is an urgent need for a curved pipe structure and a toilet to solve the above problems. Utility Model Content

[0005] According to one aspect of the present invention, an object is to provide a curved pipe structure that can improve anti-clogging performance while ensuring siphoning capacity.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] Bend pipe structure, including:

[0008] The starting pipe section, the sewage inlet straight pipe section, the rising pipe section, the falling pipe section and the outlet pipe section are connected in sequence along the extension direction. The starting pipe section is connected to the water trap of the toilet bowl. Along the extension direction, the vertical height of the starting pipe section gradually decreases, the sewage inlet straight pipe section is parallel to the horizontal direction, the vertical height of the rising pipe section gradually increases, and the vertical height of the falling pipe section gradually decreases.

[0009] As a preferred solution of the curved pipe structure provided by the present invention, the curved pipe structure further includes a bend pipe section, which is connected and arranged between the falling pipe section and the outlet pipe section, and the bend pipe section bends toward the direction close to the rising pipe section.

[0010] As a preferred solution of the curved pipe structure provided by the present invention, the curved pipe section bends toward the direction close to the rising pipe section to form a curved protrusion, and the falling pipe section bends to transition to the falling extension of the curved protrusion to form an inclination angle with the horizontal direction, and the inclination angle ranges from 10° to 20°.

[0011] As a preferred solution of the curved pipe structure provided by the present invention, the projection of the curved pipe section in the vertical direction can fall within the range of the rising pipe section.

[0012] As a preferred solution of the elbow structure provided by the present invention, there is an arc transition between the turning pipe section and the outlet pipe section.

[0013] As a preferred solution of the bent pipe structure provided by the present invention, a line connecting the center of the highest cross section of the ascending pipe section and the center of the cross section of the descending pipe section bent to the outlet of the descending section perpendicular to the vertical direction forms an angle with the vertical direction, and the range of the angle is 35°-55°.

[0014] As a preferred solution of the curved pipe structure provided by the present invention, the vertical distance between the center of the highest cross section of the rising pipe section and the center of the cross section of the falling pipe section bent to the outlet of the falling section parallel to the horizontal direction is in the range of 65mm-85mm.

[0015] As a preferred solution of the elbow structure provided by the present invention, the length of the straight sewage inlet pipe section ranges from 10 mm to 50 mm.

[0016] As a preferred solution of the elbow structure provided by the present invention, the projection of the outlet pipe section in the vertical direction can fall within the range of the rising pipe section.

[0017] According to another aspect of the present invention, an object is to provide a toilet comprising a toilet bowl and a curved pipe structure as described in any of the above schemes, wherein the curved pipe structure is connected to the toilet bowl and can discharge waste in the toilet bowl.

[0018] Beneficial effects of the utility model:

[0019] The curved pipe structure provided by the present invention includes a starting pipe section, a sewage straight pipe section, a rising pipe section, a falling pipe section and an outlet pipe section that are sequentially connected along the extension direction. The starting pipe section is connected to the water trap of the toilet bowl. Along the extension direction, the height of the starting pipe section in the vertical direction gradually decreases, and the sewage straight pipe section is parallel to the horizontal direction. The sewage straight pipe section provides a larger space to accommodate waste, has a rectifying effect, and improves the stability of fluid flow to ensure the stability of siphoning. The height of the rising pipe section in the vertical direction gradually increases, and the height of the falling pipe section in the vertical direction gradually decreases. Through the above-mentioned arrangement, waste can pass through the curved pipe structure more smoothly, while avoiding affecting the siphoning capacity of the curved pipe structure, and effectively reducing the possibility of clogging of the curved pipe structure.

[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] Figure 1 A schematic diagram of a toilet provided by an embodiment of the present utility model is shown. Figure 1 This embodiment provides a curved pipe structure and a toilet. The toilet includes a toilet bowl 10 and a curved pipe structure 1 provided in this embodiment. The curved pipe structure 1 is connected to a water trap 11 of the toilet bowl 10 and can discharge waste in the toilet bowl 10.

[0044] Figure 2 A schematic diagram showing the elbow structure provided by the embodiment of the present invention is shown, referring to Figure 2 The curved pipe structure 1 provided in this embodiment includes a starting pipe section 100, a sewage inlet straight pipe section 200, a rising pipe section 300, a falling pipe section 400, a bend pipe section 500 and an outlet pipe section 600 that are connected in sequence along its extension direction. The starting pipe section 100 is connected to the water trap 11 of the toilet bowl 10, and the height of the starting pipe section 100 in the vertical direction gradually decreases along the extension direction. Along the extension direction, the sewage inlet straight pipe section 200 is parallel to the horizontal direction. The length range of the sewage inlet straight pipe section 200 is 10mm-50mm. In this embodiment, as a preference, the length of the sewage inlet straight pipe section 200 is specifically 20mm. By providing the sewage inlet straight pipe section 200, a larger space is provided for the curved pipe structure 1 to accommodate waste, which has a rectifying effect and improves the stability of the fluid flow to ensure the stability of the siphon.

[0045] Specifically, the vertical height of the ascending pipe section 300 gradually increases along the extension direction. The vertical height of the descending pipe section 400 gradually decreases along the extension direction and bends downward toward the ascending pipe section 300. The middle portion of the bend pipe section 500 bends toward the ascending pipe section 300. This arrangement allows waste to pass through the curved pipe structure 1 more smoothly while preventing the siphoning capacity of the curved pipe structure 1 from being affected, effectively reducing the possibility of clogging of the curved pipe structure 1.

[0046] More specifically, the descending pipe section 400 bends toward the vertically lower position of the ascending pipe section 300, the vertical projection of the bend pipe section 500 can fall within the ascending pipe section 300, and the vertical projection of the outlet pipe section 600 can fall within the ascending pipe section 300. In other words, through the above arrangement, the space occupied by the curved pipe structure 1 can be reduced in both the vertical and horizontal directions, thereby improving the structural compactness.

[0047] More specifically, the arc transition between the bend pipe section 500 and the outlet pipe section 600 can improve the smoothness of the transition position between the bend pipe section 500 and the outlet pipe section 600, facilitate the flow of dirt, and avoid blockage.

[0048] More specifically, the cross section of the outlet of the outlet pipe section 600 is perpendicular to the vertical direction. This arrangement can prevent the accumulation of waste at the outlet of the outlet pipe section 600, thereby improving the smoothness of the outlet pipe section 600 in discharging waste and further preventing the elbow structure 1 from clogging.

[0049] Figure 3 The following is a partial structural diagram of the elbow structure provided by the embodiment of the present utility model. Figure 3 The line connecting the highest cross section of the ascending tube section 300, i.e., the center of the first cross section 420 of the descending section, and the cross section of the descending tube section 400 where it bends perpendicular to the vertical direction, i.e., the center of the second cross section 430 of the descending section, forms an angle ɑ with the vertical direction. The angle ɑ ranges from 35° to 55°. In this embodiment, the angle ɑ is preferably 45°.

[0050] Specifically, refer to Figure 3 The vertical distance H between the center of the first cross-section 420 of the falling section and the center of the second cross-section 430 of the falling section ranges from 65 mm to 85 mm. The height difference created by this vertical distance H provides sufficient falling distance for waste flowing through the falling pipe section 400, thereby increasing the initial velocity of waste upon entering the bend pipe section 500 and facilitating smoother waste discharge from the elbow structure 1. In this embodiment, the vertical distance H is preferably 75 mm.

[0051] For more details, please refer to Figure 3The middle part of the bend pipe section 500 is bent toward the direction close to the rising pipe section 300 to form a bend protrusion 510. The falling extension portion 410 of the falling pipe section 400 bends and transitions to the bend protrusion 510 to form an inclination angle β with the horizontal direction, and the range of the inclination angle β is 10°-20°. In this embodiment, the inclination angle β is preferably 15°. Through the above-mentioned arrangement, a smooth transition between the falling pipe section 400 and the bend pipe section 500 can be achieved, which facilitates the flow of fluids such as dirt, and by designing the angle of the inclination angle β, the flow of dirt in the bend pipe section 500 can be facilitated, avoiding the blockage of the bend pipe section 500 by dirt.

[0052] Figure 4 A schematic diagram showing a curved pipe structure without a straight sewage inlet pipe section provided by an embodiment of the present invention is shown. Figure 4 This elbow structure also features a starting section 100, an ascending section 300, a descending section 400, a bend section 500, and an outlet section 600. However, the straight sewage inlet section 200 is not provided between the starting section 100 and the ascending section 300. The lowest point of the starting section 100, i.e., the outlet, directly connects to the inlet of the ascending section 300. Experiments have shown that this elbow structure is prone to clogging.

[0053] Further, in Figure 4 In the schematic diagram of the curved pipe structure without a straight sewage inlet pipe section, the inclination angle β1 between the falling extension portion 410 where the falling pipe section 400 bends and transitions to the turning protrusion 510 and the horizontal direction, the angle ɑ1 between the line between the centers of the second cross-section 430 of the falling section and the vertical direction, and the vertical distance H1 between the center of the first cross-section 420 of the falling section and the center of the second cross-section 430 of the falling section are all outside the above-mentioned specified ranges and are prone to blockage after experimental testing.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
