Description

Technical Field

[0001] This utility model relates to the field of squat toilets, and in particular to a side-pipe water seal squat toilet. Background Technology

[0002] The existing wells in newly built unfinished houses are very shallow, about 300mm. The squat toilets that can be installed need to be less than 250mm in total height. In order to prevent odor, users will choose squat toilets with water traps. It can be seen that at present, the demand for squat toilets with water traps and a total height of less than 250mm, i.e., water-sealed squat toilets, is becoming increasingly strong in both public buildings and home decoration.

[0003] However, the structure of water-sealed squat toilets currently on the market is a standard straight pipe. In order to meet national standards, the depth of the washing surface must be more than 90mm to prevent urine rebound, and the water channel must be able to pass through a solid ball with a diameter of not less than 46mm, the water seal depth must be not less than 50mm, and the cut must be not less than 50mm. In addition, there are limitations such as the thickness of the ceramic body and the slope and height of the toilet bowl. Under these circumstances, it is difficult for water-sealed squat toilets to achieve a total height of less than 250mm. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose a side-pipe water seal squat toilet, which solves the problem that existing water seal squat toilets, while meeting national standards, have a total height that is difficult to be less than 250mm.

[0005] To achieve this objective, the present invention adopts the following technical solution: A side-pipe water seal squat toilet, including a pedal and a urinal; The toilet bowl is connected below the pedal; The toilet bowl has an arc-shaped surface and a sewage discharge section. The end of the arc-shaped surface is connected to the sewage discharge section. A sealing cavity is connected below the sewage discharge section. The sealing cavity is used to form a water cover at the sewage discharge section. The sealing cavity is connected to a sewage pipe through a drainage pipe. The drainage pipe is formed by the outer bottom surface of the arc-shaped surface and the drainage trough. The sewage pipe is located directly below the outer bottom surface of the arc-shaped surface and is connected to the drainage trough. The drainage pipe does not extend along the center line O of the arc-shaped surface; the sewage pipe is located to the left or right of the center line O. The distance h between the top of the pedal and the bottom of the toilet bowl is 240-250mm.

[0006] Preferably, in the vertical projection, the outer wall contour of the sewage pipe is located within the outer periphery contour of the arc-shaped surface.

[0007] Furthermore, the drainage channel has a U-shaped cross-section with different heights at both ends, a thickness of 10mm, an opening width w1 of 81.5-87.5mm, a distance w2 between the higher end of the drainage channel's cross-section and the lowest point of the inner wall of the drainage channel, and a distance w3 between the lower end of the drainage channel's cross-section and the lowest point inside the drainage channel, which is 33.5-39.5mm.

[0008] Preferably, in the vertical direction, the shortest distance s1 between the outer pipe wall outline of the sewage pipe and the sealing cavity is 213-220mm; The distance s2 between the center of the sewage pipe and the centerline O is 73-80mm.

[0009] Preferably, in the vertical projection, the outer wall contour of the sewage pipe is tangent to the outer peripheral contour of the arc-shaped surface.

[0010] Preferably, a sewage outlet is formed at the tail end of the sewage discharge section, and the inlet of the sewage pipe is higher than the sewage outlet.

[0011] Preferably, the drainage pipe is S-shaped when projected in the vertical direction.

[0012] Preferably, the sewage discharge section is offset outward and is in the shape of an arc-shaped tube.

[0013] Preferably, the outlet of the sewage pipe faces downwards.

[0014] Preferably, the pedal is provided with a plurality of anti-slip grooves, which are arranged in parallel.

[0015] The technical solution provided by this utility model can include the following beneficial effects: This solution provides an off-center water seal squat toilet. By setting an off-center drainage pipe at the bottom of the arc-shaped surface, and utilizing the arc space at the bottom of the arc-shaped surface, the distance between the inlet of the sewage pipe and the lowest point of the concave arc-shaped surface is shortened while meeting the ball-passing index. This reduces the structural height required to meet the water seal depth index, thereby lowering the overall height of the water seal squat toilet and meeting installation requirements. At the same time, the drainage pipe and the arc-shaped surface are not separated, which facilitates mold preparation, production operation, and control of product consistency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] A side-pipe water seal squat toilet includes a pedal 1 and a toilet bowl 2; The toilet bowl 2 is connected below the pedal 1; The toilet bowl 2 has an arc-shaped surface 21 and a sewage discharge section 22. The end of the arc-shaped surface 21 is connected to the sewage discharge section 22. A sealing cavity 23 is connected below the sewage discharge section 22. The sealing cavity 23 is used to form a water cover at the sewage discharge section 22. The sealing cavity 23 is connected to the sewage discharge pipe 25 through a drainage pipe 24. The drainage pipe 24 is formed by the outer bottom surface 210 of the arc-shaped surface 21 and the drainage channel 241. The sewage discharge pipe 25 is located directly below the outer bottom surface 210 of the arc-shaped surface 21 and is connected to the drainage channel 241. The drainage pipe 24 does not extend along the center line O of the arc surface 21, and the sewage pipe 25 is located to the left or right of the center line O. The distance h between the top of the pedal 1 and the bottom of the toilet bowl 2 is 240-250mm.

[0025] Existing water-sealed squat toilets use a standard straight pipe. To meet national standards, and considering production and functionality, while ensuring a 90mm washing surface depth, the ball seal must be ≥46mm, the water seal ≥50mm, and the cut ≥50mm. Adding the ceramic body thickness and the slope of the washing surface, the total height of the water-sealed squat toilet reaches 265mm under ideal conditions. Moreover, in actual production, due to firing and deformation, the total height is even higher. To solve the problems existing in the current technology, this utility model proposes an off-pipe water-sealed squat toilet, such as... Figure 1 - Figure 3 As shown, compared to conventional water-sealed squat toilets, the drain pipe 24 of this off-center water-sealed squat toilet does not extend along the center line O of the arc-shaped surface 21. The drain pipe 25 is located to the left or right of the center line O. That is, the drain pipe 24 is offset from the center line O of the arc-shaped surface 21. Conventional water-sealed squat toilets need to use the lowest point of the concave area of ​​the arc-shaped surface 21 as a reference to increase the total height to meet the standards for ball and water seal. However, this off-center water-sealed squat toilet does not need to use the lowest point of the concave area of ​​the arc-shaped surface 21 as a reference. The drain pipe 24... 4. After the offset occurs, the bottom arc space of the arc surface 21 can be used to increase the cross-sectional area of ​​the drainage pipe 24 to meet the requirements of the ball passage. At the same time, the height of the water seal surface is effectively increased. When the water seal depth requirement is met, the distance between the lowest point of the concave part of the arc surface 21 and the bottom of the toilet bowl 2 is smaller than that of conventional water seal squat toilets. Ultimately, the overall height is effectively shortened, so that the total height is less than 250mm and meets the national standard requirements. This solves the problem that the total height of existing water seal squat toilets is difficult to be less than 250mm when meeting the national standard.

[0026] Meanwhile, the drainage pipe 24 is formed by the outer bottom surface 210 of the arc-shaped surface 21 and the drainage groove 241, that is, the drainage pipe 24 and the arc-shaped surface 21 are not separated. The drainage pipe 24 is close to the bottom of the arc-shaped surface 21, retaining the general direction of the pipe of a conventional water seal squat toilet, without making large-scale bending operations, ensuring that the water seal squat toilet can realize the function of flushing and sewage discharge. At the same time, there is no need to make any small parts to support the empty pipe for mold preparation, which is conducive to the production of high pressure mold, improves molding accuracy, reduces deformation risk, facilitates production operation and controls product consistency.

[0027] It is worth noting that the arc surface 21 has different curvatures depending on the requirements and radii. The curvature of the arc surface 21 directly affects the ball seal and water seal, and needs to be designed according to national standards to meet the water seal and ball seal specifications. Preferably, the curvature of the arc surface 21 is 48-49.5°.

[0028] Preferably, in the vertical direction, the outline of the outer wall of the sewage pipe 25 is located within the outer periphery outline of the arc-shaped surface 21.

[0029] Specifically, the drain pipe 25 does not exceed the width of the arc-shaped surface 21, effectively preventing the production difficulties caused by the drain pipe 25 exceeding the range of the arc-shaped surface 21.

[0030] Furthermore, the drainage channel 241 has a U-shaped cross-section with different heights at both ends. The drainage channel 241 has a thickness of 10mm, an opening width w1 of 81.5-87.5mm, a distance w2 between the higher end of the cross-section of the drainage channel 241 and the lowest point of the inner wall of the drainage channel 241 of 70.5-76.5mm, and a distance w3 between the lower end of the cross-section of the drainage channel 241 and the lowest point inside the drainage channel 241 of 33.5-39.5mm.

[0031] like Figure 4 As shown, the dimensions of the drainage pipe 24 are limited to ensure that the drainage pipe 24 meets the ball passage index while meeting the water seal requirements, and the overall height is less than 250mm.

[0032] Preferably, in the vertical direction, the shortest distance s1 between the outer wall outline of the sewage pipe 25 and the sealing cavity 23 is 213-220mm. The distance s2 between the center of the sewage pipe 25 and the centerline O is 73-80mm.

[0033] like Figure 2As shown, under this constraint, while ensuring that the water cover is higher than the lowest point of the concave arc surface 21, the path length of the drainage pipe 24 is minimized as much as possible to ensure the flushing and sewage discharge function of the drainage pipe 24. This effectively prevents the water cover from being formed due to the excessive length of the drainage pipe 24. If the water in the sealing cavity 23 is not filled, a normal water cover will not be formed, affecting the pressure ratio inside and outside the drainage pipe 24, thus causing the water in the drainage pipe 24 to be pushed back towards the arc surface 21.

[0034] Preferably, in the vertical projection, the outer wall contour of the sewage pipe 25 is tangent to the outer peripheral contour of the arc-shaped surface 21.

[0035] like Figure 2 As shown, the sewage pipe 25 is deviated to the centerline O of the arc-shaped surface 21 to the greatest extent possible, adapting to the arc-shaped surface 21. A cross-sectional view is then taken under this structure (e.g., Figure 4 As shown in the figure, the cross-section of the drainage pipe 24 can be seen. The cross-sectional area of ​​the sewage pipe 25 is about 1 / 4 to 2 / 5 larger than that of a conventional water seal squat toilet, which effectively reduces the risk of blockage and meets the requirements of ball passage.

[0036] Preferably, a drain outlet 221 is formed at the tail end of the drain section 22, and the inlet of the drain pipe 25 is higher than the drain outlet 221.

[0037] like Figure 3 As shown, the inlet of the drain pipe 25 is higher than the drain outlet 221. Specifically, the lowest point of the inlet of the drain pipe 25 in the vertical direction and the drain outlet 221 will be filled with water. The height difference between the two is the water seal depth. Because the arc surface 21 has an arc, and the drain pipe 25 is located to the left or right of the center line O, by utilizing the bottom arc space of the arc surface 21, the distance between the inlet of the drain pipe 25 and the lowest concave point of the arc surface 21 is shortened. Under the condition of meeting the national standard water seal depth, the distance between the drain outlet 221 and the lowest concave point of the arc surface 21 is also shortened, so that the position of the sealing cavity 23 connected below the drain section 22 is moved upward relative to the pedal 1, thus effectively shortening the total height of the water seal squat toilet.

[0038] The sealing cavity 23 is an existing structure that uses retained water for sealing. The inlet of the sewage pipe 25 is higher than the sewage outlet 221, which effectively prevents odor from flowing back into the toilet bowl 2 through the sewage outlet 221.

[0039] Preferably, the drainage pipe 24 is S-shaped when projected in the vertical direction.

[0040] like Figure 2As shown, the drainage pipe 24 is S-shaped, which can effectively guide the sewage to flow along the center of the drainage pipe 24, reduce the sewage from accumulating at the edge of the drainage pipe 24, and reduce the risk of sewage accumulation in the drainage pipe 24.

[0041] Preferably, the sewage discharge section 22 is offset outward and is in the shape of an arc-shaped tube.

[0042] Specifically, such as Figure 3 As shown, the sewage discharge section 22 is an arc-shaped tube that is offset outwards, and the water surface is partially blocked from top to bottom. The wall of the sewage discharge section 22 can prevent water from the sealed cavity 23 from splashing onto the user.

[0043] Preferably, the outlet of the sewage pipe 25 faces downward.

[0044] Specifically, such as Figure 2 As shown, the downward-facing outlet of the sewage pipe 25 facilitates connection with pipes installed on the ground.

[0045] Preferably, the pedal 1 is provided with a plurality of anti-slip grooves 11, which are arranged in parallel.

[0046] Specifically, such as Figure 1 As shown, the anti-slip groove 11 increases the coefficient of friction of the pedal 1 surface, improves the stability when the user contacts the pedal 1, reduces the risk of slipping accidents during use, and thus ensures the user's safety.

[0047] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
