Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of toilets, in particular to a bent pipe structure and a toilet. Background Art
[0002] Most existing toilets use a jet siphon to drain waste. The stronger the flush, the louder the noise from the siphon, especially at night when it's quiet.
[0003] The existing technology typically requires adding a downpipe in front of the siphon bend in the curved pipe structure connected below the toilet's sewage outlet to shield the noise during the siphoning process. This method is not effective in reducing noise, and the addition of a downpipe increases the vertical footprint of the curved pipe structure, hindering structural compactness.
[0004] Therefore, there is an urgent need for a curved pipe structure and a toilet to solve the above problems. Utility Model Content

[0009] The cross section of the starting pipe section is wide at the top and narrow at the bottom;
[0010] Along the extension direction, the height of the starting pipe section (100) gradually decreases, and along the extension direction, the height of the rising pipe section (200) gradually increases. A sewage inlet (600) is formed between the lowest point of the starting pipe section (100) and the lowest point of the rising pipe section (200). The cross section of the sewage inlet (600) presents a structure that is wide at the top and narrow at the bottom.
[0011] As a preferred solution of the curved pipe structure provided by the present invention, along the extension direction, the cross section of the rising pipe section (200) transitions from a wide upper portion and narrow lower portion structure to an elliptical shape; and / or,
[0012] Along the extension direction, the cross section of the drop tube section (300) transitions from an elliptical shape to a circular shape; and / or,

[0015] As a preferred solution of the elbow structure provided by the present invention, the ratio of the cross-sectional area of the sewage inlet to the cross-sectional area of the highest point of the rising pipe section is in the range of 1.7-2.3.
[0016] As a preferred solution of the elbow structure provided by the present invention, along the extension direction of the elbow structure, within the range from the cross section at the entrance of the starting pipe section to the cross section at the entrance of the outlet pipe section, the ratio of the areas of two adjacent cross sections is in the range of 1-1.4.
[0017] As a preferred solution of the curved pipe structure provided by the present invention, in the curved pipe structure, the ratio S1 of the major axis to the minor axis of the cross section of the curved pipe structure with a wide upper portion and narrow lower portion is in the range of 1<S1≤1.3.
[0018] As a preferred solution of the curved pipe structure provided by the present invention, in the curved pipe structure, the ratio S2 of the major axis to the minor axis of the elliptical cross section is in the range of 1<S2≤1.1.
[0019] As a preferred solution of the curved pipe structure provided by the present invention, the projection of the turning pipe section in the vertical direction and the projection of the outlet pipe section in the vertical direction can both fall within the range of the rising pipe section; the middle part of the turning pipe section bends toward the direction close to the rising pipe section; the middle part of the outlet pipe section bends toward the direction away from the rising pipe section.
[0020] As a preferred solution of the curved pipe structure provided by the present invention, in the horizontal direction, the curved pipe section extends toward the water trap.
[0021] 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 one of the above schemes, wherein the curved pipe structure is connected to the toilet bowl and can discharge waste in the toilet bowl.
[0022] Beneficial effects of the utility model:
[0023] The curved pipe structure provided by the present invention includes a starting pipe section, an ascending pipe section, a descending pipe section, a bend pipe section, and an outlet pipe section, which are sequentially connected along the extension direction.

The cross-section of the starting pipe section is a wide-upper-narrow-lower structure, and the cross-section of the sewage inlet is a wide-upper-narrow-lower structure. Through the above-mentioned arrangement, the airflow velocity during siphoning can be effectively reduced, thereby reducing noise, and even with a larger pipe diameter, the curved pipe structure can still ensure that it has sufficient siphoning force. In other words, the curved pipe structure can effectively reduce siphoning noise without changing the space occupied by the curved pipe structure by rationally designing the shape of the cross section and selecting the cross-sectional area.

[0045] 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.
[0046] Figure 1 A schematic diagram showing a toilet provided by an embodiment of the present utility model is shown; Figure 2 The schematic diagram of the elbow structure provided by the embodiment of the present utility model is shown. Figure 1 and Figure 2 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.
[0047] Specifically, the curved pipe structure 1 includes a starting pipe section 100, an ascending pipe section 200, a descending pipe section 300, a bend pipe section 400, and an outlet pipe section 500, which are sequentially connected along the extension direction. The starting pipe section 100 is connected to the trap 11 of the toilet bowl 10. The height of the starting pipe section 100 gradually decreases along its extension direction. The height of the ascending pipe section 200 gradually increases along its extension direction, with a sewage inlet 600 formed between the lowest point of the starting pipe section 100 and the lowest point of the ascending pipe section 200. The height of the descending pipe section 300 gradually decreases along its extension direction, extending horizontally toward a position below the ascending pipe section 200 in the vertical direction. Horizontally, the bend pipe section 400 extends toward the water trap 11. The vertical projections of the bend pipe section 400 and the outlet pipe section 500 both fall within the riser pipe section 200. The central portion of the bend pipe section 400 curves toward the riser pipe section 200, while the central portion of the outlet pipe section 500 curves away from the riser pipe section 200. This arrangement reduces the space occupied by the elbow structure 1 in both the vertical and horizontal directions, improving its compactness.
[0048] More specifically, the cross-section of the starting pipe section 100 is wide at the top and narrow at the bottom. This arrangement ensures that the curved pipe structure 1 maintains sufficient siphoning power even with a larger pipe diameter (e.g., 50 mm). It also effectively reduces the airflow velocity during siphoning, thereby reducing noise.
[0049] More specifically, the diameter of the curved pipe structure 1 gradually decreases along the extension direction of the curved pipe structure 1. Through the above arrangement, the air flow velocity of the curved pipe structure 1 during siphoning can be further reduced, thereby reducing noise.
[0050] More specifically, along the extension direction of the ascending pipe section 200, the cross-section of the ascending pipe section 200 transitions from a wide-at-top, narrow-at-bottom structure to an elliptical shape, the cross-section of the descending pipe section 300 transitions from an elliptical shape to a circular shape, and the cross-section of the bend pipe section 400 is a circular shape. In other words, the curved pipe structure 1 can effectively reduce siphon noise without increasing the space occupied by the curved pipe structure 1 by designing its cross-sectional shape along the extension direction and selecting the appropriate cross-sectional area.

Figure 2 and Figure 3Along the extension direction of the starting pipe section 100, from the entrance position of the connection between the starting pipe section 100 and the water trap 11 to the sewage inlet 600, a starting first cross-section 110, a starting second cross-section 120, and a starting third cross-section 130 are intermittently cut, wherein the starting first cross-section 110 is the inlet cross-section of the starting pipe section 100.

[0054] More specifically, the ratio of the cross-sectional area of the sewage inlet 600 to the cross-sectional area of the highest point of the riser section 200 is in the range of 1.7-2.3. In this embodiment, the ratio of the cross-sectional area of the sewage inlet 600 to the cross-sectional area of the highest point of the riser section 200 is preferably 2.0.

[0058] More specifically, in the curved tube structure 1, the ratio S1 of the major axis to the minor axis of the cross section of the structure with a wide upper portion and narrow lower portion is in the range of 1<S1≤1.3. In this embodiment, the range of S1 is preferably 1<S1≤1.2.
