Description

Technical Field

[0001] The present invention relates to the field of ceramic sanitary wares, and particularly to a squatting pan with good flushing effect and a preparation method thereof. Background Art

[0002] In the prior art, the forming of a squatting pan can be divided into atmospheric pressure forming and high-pressure forming. Atmospheric pressure forming is to use a plaster mold for grouting under atmospheric pressure and then demold to form a squatting pan. This forming method requires a large number of small mold parts, and in the forming process, mold loading and demolding are required, with a very long operation time and low production efficiency.

[0003] High-pressure forming refers to using a resin mold to form the main body of a squatting pan by grouting under a relatively high pressure. Since the grouting pressure is relatively high, it is required to use as few small mold parts as possible. In the prior art (such as CN 20191060044.2), generally, the squatting pan is divided into a panel and a bladder and formed separately, and its flushing structure is arranged in the panel. However, limited by the mold structure, the flushing effect of the squatting pan formed by this forming method is often relatively poor. In addition, using this forming method, one set of molds is required for one product, which limits the production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a squatting pan with good flushing effect, which has a good flushing effect and does not splash water.

[0005] To solve the above technical problem, the present invention discloses a squatting pan with good flushing effect, which includes a separately integrally formed panel and a separately integrally formed bladder, and the panel and the bladder are bonded to form a squatting pan;

[0006] The bladder includes a siphon elbow, a toilet bowl, a water inlet pipe, a water guide cavity and a water outlet hole. The water guide cavity is arranged above the toilet bowl, and the water outlet hole is arranged at the top of the water guide cavity so that flushing water is discharged from the water outlet hole;

[0007] A baffle is arranged on the inner peripheral surface of the panel, and the baffle extends into the interior of the toilet bowl to form a flushing hole between the baffle and the inner wall of the toilet bowl, and the flushing water discharged from the water outlet hole enters the toilet bowl through the flushing hole.

[0008] As an improvement of the above technical solution, a swirling baffle is further arranged on the top surface of the water guide cavity, and the swirling baffle is inclined relative to the outer side wall of the bladder.

[0009] As an improvement of the above technical solution, a plurality of swirling baffles are arranged on the top surface of the water guide cavity, and the water outlet hole is arranged between the adjacent swirling baffles.

[0010] As an improvement of the above technical solution, the water outlet holes include a first water outlet hole and a second water outlet hole, and the aperture of the first water outlet hole is larger than that of the second water outlet hole.

[0011] As an improvement of the above technical solution, a stepped portion is provided at the outlet of the siphon elbow, and the stepped portion is disposed around the inner wall of the siphon elbow.

[0012] As an improvement of the above technical solution, the width of the stepped portion: the width of the water inlet of the siphon elbow = (3 - 5):1.

[0013] As an improvement of the above technical solution, the stepped portion includes a first stepped portion and a second stepped portion, and the first stepped portion is disposed above the second stepped portion;

[0014] The first stepped portion gradually widens from the side close to the water inlet of the siphon elbow to the side away from the water inlet of the siphon elbow.

[0015] As an improvement of the above technical solution, the maximum width of the first stepped portion is greater than the width of the second stepped portion.

[0016] As an improvement of the above technical solution, the maximum width of the first stepped portion: the width of the second stepped portion = (1.5 - 2.5):1.

[0017] As an improvement of the above technical solution, a water replenishing hole is provided on the inner wall of the water guiding cavity near the water inlet pipe, and the water replenishing hole is disposed close to the bottom surface of the water guiding cavity.

[0018] Implementing the present invention has the following beneficial effects:

[0019] 1. For the squatting pan of the present invention, a water guiding cavity is provided at the top of the bladder bag, and water outlet holes are provided on the top surface of the water guiding cavity, and then the flushing water ejected from the water outlet holes is guided into the toilet bowl through the baffle structure of the panel; the flushing effect is improved, and splashing is effectively avoided.

[0020] 2. For the squatting pan of the present invention, the flushing structure (water guiding cavity, water outlet holes, water inlet pipe, etc.) is arranged in the bladder bag structure, greatly simplifying the structure of the panel, enabling the panel to adopt a double-sided pulp structure, and improving its strength. At the same time, it also enables a panel to be adapted to multiple bladder bags, improving production efficiency. In addition, through this structural design, the height of the squatting pan can be effectively reduced under the condition of the same bladder bag slope.

[0021] 3. For the squatting pan of the present invention, inclined swirling small baffle strips are provided beside the water outlet holes, increasing the swirling effect of the flushing water and improving the flushing effect.

[0022] 4. The squatting pan of the present invention is provided with a stepped portion at the outlet of the siphon elbow, which can make the flushing sewage fully turbulent and enhance the siphon effect. Further, by controlling the width and the number of the stepped portions, the flushing effect can be effectively improved. The squatting pan in the present invention can flush out more than 3 sponge strips, which is far superior to the traditional squatting pan.

[0023] 5. The squatting pan of the present invention is provided with water replenishing holes on the inner wall of the water guiding cavity near the water inlet pipe, which can replenish the water seal; at the same time, it can also make the residual flushing water in the water guiding cavity flow out fully after flushing, avoiding excessive dirt deposition in the water guiding cavity.

[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inner and outer that appear or will appear in the text of the present invention are only based on the drawings of the present invention and are not specific limitations on the present invention.

[0033] Refer to Figures 1 to 3, the present invention provides a squat toilet with good flushing effect, which includes a separately integrally formed panel 1 and a separately integrally formed bladder 2. The panel 1 and the bladder 2 are bonded, glazed, and fired to form a finished squat toilet. Separating the panel 1 and the bladder 2 for forming greatly simplifies the structure of the panel, enabling the panel to adopt a double-sided slurry structure, enhancing its strength. At the same time, it also enables a single panel to be adapted to multiple bladders, improving production efficiency. In addition, through this structural design, the height of the squat toilet can be effectively reduced under the condition of the same bladder slope.

[0034] Among them, the panel 1 includes a panel body 11, a baffle 12, and an anti-slip part 13; among them, the baffle 12 is arranged around the inner peripheral surface of the panel 1 to cooperate with the bladder 2 to form a flushing structure. The anti-slip part 13 is arranged on both sides of the panel, and it can be multiple convex strips or grooves, but is not limited thereto.

[0035] Furthermore, referring to Figure 4 , a plurality of convex parts 14 are also arranged on the back surface of the panel 1, which are arranged around the outside of the baffle 12, and can facilitate the positioning of the panel 1 and the bladder 2 during bonding.

[0036] Referring to Figures 3 to 5 , the bladder 2 includes a toilet bowl 21, a water inlet pipe 22, a water guide cavity 23, a water outlet hole 24, and a siphon elbow 25; among them, the water guide cavity 23 is arranged around the top of the bladder 2 and is connected to the water inlet pipe 22; the water outlet hole 24 is arranged on the top surface of the water guide cavity 23. A flushing hole 26 is formed between the baffle 11 and the inner wall of the toilet bowl 21. During flushing, the flushing water enters the water guide cavity 23 from the water inlet pipe 22, and then rushes upward through the water outlet hole 24 on the top surface of the water guide cavity 23, and then is discharged into the toilet bowl 21 from the flushing hole 26 under the diversion of the panel body 11 and the baffle 12. This structure forms a waterfall flushing, strengthening the flushing effect and effectively preventing splashing.

[0037] Furthermore, referring to Figure 5 , in order to improve the flushing effect, a plurality of swirling baffle strips 27 are also arranged on the top of the bladder 2, which are arranged on the outer side of the top surface of the water guide cavity 23, and the swirling baffle strips 27 are inclined relative to the outer wall of the bladder. The swirling baffle strips 27 can further divert the flushing water rushed out from the water outlet hole 24, prompting the water flow to enter the toilet bowl 21 at a specific angle, thereby forming a super-whirl flushing and strengthening the flushing effect.

[0038] Specifically, in this embodiment, a plurality of swirling baffle strips 27 are arranged on the top of the bladder 2, and one or more water outlet holes 24 are arranged between adjacent swirling baffle strips 27; preferably, one water outlet hole 24 is arranged between adjacent swirling baffle strips 27.

[0039] Specifically, referring to Figure 5, the water outlet holes 24 include a first water outlet hole 241 and a second water outlet hole 242, and the aperture diameter (water outlet area) of the first water outlet hole 241 is larger than that of the second water outlet hole 242. The first water outlet hole 241 has a larger water outlet area, with a large water output but a small water outlet speed. The second water outlet hole 242 has a smaller water outlet area, with a small water output but a large water outlet speed. The shapes of the first water outlet hole 241 and the second water outlet hole 242 are oval, circular, rectangular, square, etc., but are not limited thereto; preferably, the first water outlet hole 241 is oval, and the shape of the second water outlet hole 242 is circular; the major axis and minor axis of the first water outlet hole 241 are both larger than the aperture diameter of the second water outlet hole 242.

[0040] Specifically, the number of the first water outlet holes 241 and the second water outlet holes is 6 - 10, but is not limited thereto. Preferably, there are 8 first water outlet holes 241 and 8 second water outlet holes 242 provided on the water guiding cavity 23. According to people's usage habits and the flushing characteristics of the squatting pan, 4 - 6 first water outlet holes 241 and 2 - 3 second water outlet holes 242 are arranged on the side of the toilet bowl 21 far from the water inlet of the siphon elbow 25. Since the side far from the water inlet of the siphon elbow 25 is the sewage receiving surface, the drop of the flushing water is small and the travel distance is long. Therefore, more first water outlet holes 241 are arranged to increase the water output to fully flush the sewage receiving surface of the toilet bowl 21 and optimize the flushing effect. More second water outlet holes 242 are arranged on the side close to the water inlet of the siphon elbow 25, which can increase the water speed entering the siphon elbow 25 and optimize the siphon effect. Through the cooperation of the first water outlet holes 241 and the second water outlet holes 242, not only the flushing effect can be optimized, but also water can be effectively saved.

[0041] Specifically, referring to Figure 6 , Figure 7 , the siphon elbow 25 is arranged at the bottom of the toilet bowl 21, and a step portion 28 is arranged at its outlet. The step portion 28 can further turbulize the flushing water discharged from the siphon elbow 25, thereby enhancing the siphon effect. In order to prevent the step portion 28 from forming a swirling flow and weakening the flushing effect, the width of the step portion 28 should be controlled: the width of the water inlet of the siphon elbow 25 = (3 - 5):1; when the width of the step portion 28 < 1 / 5 of the width of the water inlet of the siphon elbow 25, effective turbulization cannot be achieved. When the width of the step portion 28 < 1 / 3 of the width of the water inlet of the siphon elbow 25, the reeling wave formed by the flushing water will instead hinder the flushing water and weaken the flushing effect.

[0042] Specifically, the step portion 28 includes a first step portion 281 and a second step portion 282. The first step portion 281 gradually widens from the side close to the water inlet of the siphon bend 25 to the side away from the water inlet of the siphon bend 25, and the width of the second step portion 282 remains constant. The first step portion 281 is arranged above the second step portion 282. When the flushing water flows through the step portion 28, it is first blocked by the first step portion 281 to form the first turbulence; and then it is blocked by the second step portion 282 to form the second turbulence. The step portion 28 of this structure can better improve the siphon effect.

[0043] Specifically, the maximum width of the first step portion 281 is greater than the width of the second step portion 282. Specifically, the maximum width of the first step portion: the width of the second step portion = (1.5-2.5): 1; exemplary are 1.5: 1, 1.7: 1, 1.9: 1, 2: 1, but not limited thereto. Specifically, when the maximum width of the first step portion 281 is greater than 2.5 times the width of the second step portion 282, part of the vortex-shaped water flow formed by the first step portion 281 will not collide with the second step portion 282, weakening the flushing effect. When the maximum width of the first step portion 281 is less than 1.5 times the width of the second step portion 282, the vortex water flow formed by the first step portion 281 is weak, and the collision is concentrated only on one side of the second step portion 282. It is difficult for the second step portion 282 to effectively play its role, weakening the flushing effect.

[0044] Specifically, in order to further optimize the siphon effect, the height difference between the first step 281 and the second step 282 should be controlled to be 100-500 mm, preferably 100-200 mm, and exemplary examples may be 110 mm, 120 mm, 125 mm, 130 mm, 155 mm, 180 mm, 190 mm, but not limited thereto.

[0045] Specifically, in this embodiment, a water replenishment hole 29 is also provided on the water guide cavity 23, which is arranged near the bottom surface of the water guide cavity 23, so that after the flushing is completed, the residual flushing water in the water guide cavity 23 is discharged from the water replenishment hole 29 to replenish the water seal, and at the same time, the flushing water is prevented from remaining in the water guide cavity and depositing dirt. It should be noted that since the siphon effect of the squat toilet in the present invention is strong, the water seal is too low after flushing, so the water replenishment hole 29 is provided. Further, in order to cooperate with the outflow of residual water, the present invention sets the water replenishment hole 29 on the inner wall of the water guide cavity 23 near the water inlet pipe 22.

[0046] The flushing effect of the present invention is described below with specific test examples:

A stepped portion 28 is provided at the bottom of the siphon elbow 25, which gradually widens from the side close to the water inlet of the siphon elbow to the side far from the water inlet of the siphon elbow, and its maximum width: the width of the water inlet of the siphon elbow = 4:1.
