[0002] Most ceramic toilets are jet siphon toilets. The water inlet of the flushing channel is connected to the water tank, and the connection or disconnection between the water inlet of the flushing channel and the water tank is achieved through the drain valve. The water outlet of the flushing channel extends to the main punching hole at the bottom of the toilet bowl. When flushing, the drain valve opens, and the water in the water tank flows along the flushing channel to the main punching hole at the bottom of the toilet bowl under the action of gravity to spray and flush away the dirt.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0055] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0056] like Figure 1 , Figure 2 as well as Figure 3As shown, this embodiment provides a toilet body 100, including a wash ring 1, a pot surface 2, a water trap 3 and a drain bend 4 connected in sequence from top to bottom. The wash ring 1 is specifically arranged in the circumference of the upper edge of the pot surface 2, and the pot surface 2, the water trap 3 and the drain bend 4 form the toilet bowl of the toilet. The cross-sectional area of ​​the water trap 3 is smaller than the cross-sectional area of ​​the pot surface 2, and the cross-sectional area of ​​the drain bend 4 is smaller than the cross-sectional area of ​​the water trap 3. That is, the cross-sectional area of ​​the toilet bowl gradually decreases from top to bottom. The wash ring 1 is provided with a first wash ring water outlet 111 and a second wash ring water outlet 121 for discharging water. The water flow at the first washing ring water outlet 111 can flow along the circumference of the washing ring 1 to the front end of the pot surface 2, and is divided at the front end of the pot surface 2 to the water trap 3 to form a first water flow and to the second washing ring water outlet 121 to form a split water flow; the water flow at the second washing ring water outlet 121 can flow along the circumference of the washing ring 1 to the first washing ring water outlet 111, and converge with the water flow output from the first washing ring water outlet 111 to form a second water flow; the split water flow converges with the water flow output from the second washing ring water outlet 121 to form a third water flow. Among them, the flow rate of the first water flow is greater than the flow rate of the second water flow, and the flow rate of the first water flow is greater than the flow rate of the third water flow.

[0057] For flushing, see Figure 3 , water flows out through the first washing ring water outlet 111 and the second washing ring water outlet 121 on the washing ring 1, the water flowing out of the first washing ring water outlet 111 flows along the circumference of the washing ring 1 to the front end of the pot surface 2, and is divided at the front end of the pot surface 2, so that a part of the water flows downstream along the front end of the pot surface 2 to form a first water flow, and the first water flow directly enters the water trap 3; the water flowing out of the second washing ring water outlet 121 flows along the circumference of the washing ring 1 to the first washing ring water outlet 111, and converges with the water flowing out of the first washing ring water outlet 111 near the first washing ring water outlet 111 to form a second water flow; another part of the water flow divided at the front end of the pot surface 2 passes over the front end of the pot surface 2 and continues to flow until it reaches the second washing ring water outlet 121, and converges with the water flowing out of the second washing ring water outlet 121 near the second washing ring water outlet 121 to form a third water flow. That is, when the toilet body 100 is flushed, a stream of water is formed at the first wash ring outlet 111, the second wash ring outlet 121 and the front end of the pot surface 2. The first stream of water, the second stream of water and the third stream of water formed eventually rotate into the water trap 3 and the drainage bend 4, and the waste is discharged by inducing the siphon of the drainage bend 4. Since the cross-sectional area of ​​the water trap 3 is smaller than the cross-sectional area of ​​the pot surface 2, and the cross-sectional area of ​​the drainage bend 4 is smaller than the cross-sectional area of ​​the water trap 3, the water flow can accelerate the rotation at the water trap 3 and further accelerate at the inlet end of the drainage bend 4 to quickly discharge the waste. The toilet provided in this embodiment forms three streams of water for flushing, eliminates the main flushing hole at the bottom of the toilet bowl, and can effectively reduce the flushing noise compared to the toilet that flushes by jetting through the main flushing hole in the prior art.

[0058] At the same time, the flow rate of the first water flow formed is greater than the flow rate of the second water flow, and greater than the flow rate of the third water flow, that is, the water flow that flows to the front end of the pot surface 2 and directly flows to the water trap 3 at the front end of the pot surface 2 has the largest flow rate. By increasing the flow rate of the first water flow, the flushing water flow can be made to rush to the water inlet 41 of the drainage bend pipe 4 faster and more fully. At the same time, combined with the vortex flushing water flow formed by the second and third water flows, while ensuring the silent effect, the flushing force and water flow speed are increased, and the drainage bend pipe 4 can form a siphon to discharge sewage faster. The first water flow with a large flow rate has a large potential energy, which can improve the flushing ability, ensure that the sewage is flushed away, and improve the flushing speed and sewage discharge performance of the toilet.

[0059] Furthermore, in actual application, the flow rate of the second water flow may also be greater than that of the third water flow.

[0060] In this embodiment, the first wash ring water outlet 111 and the second wash ring water outlet 121 are respectively arranged on both sides of the center line M of the toilet, and the water outlet direction of the first wash ring water outlet 111 is toward the front end of the pot surface 2, and the water outlet direction of the second wash ring water outlet 121 is toward the rear end of the pot surface 2. Figure 3 In the direction of the toilet, the first wash ring water outlet 111 and the second wash ring water outlet 121 are respectively arranged on the left and right sides of the center line M of the toilet, the water flow from the first wash ring water outlet 111 flows counterclockwise toward the front end of the pot surface 2, and is divided at the front end of the pot surface 2, and the water flow from the second wash ring water outlet 121 flows counterclockwise toward the rear end of the pot surface 2, and converges with the water flow at the first wash ring water outlet 111 when reaching the first wash ring water outlet 111. That is, the overall water flow direction of the first wash ring water outlet 111 and the second wash ring water outlet 121 is consistent, and both rotate and flow in the counterclockwise direction to achieve rotary flushing and sewage discharge.

[0061] Continue reading Figure 3 The washing ring 1 is provided with a water inlet 10, a first flow channel 11 and a second flow channel 12 connected to the water inlet 10, the end of the first flow channel 11 away from the water inlet 10 forms a first washing ring water outlet 111, and the end of the second flow channel 12 away from the water inlet 10 forms a second washing ring water outlet 121. The first flow channel 11 and the second flow channel 12 can realize the diversion of water flow at the water inlet 10. Specifically, a water inlet is installed at the water inlet 10, and the water inlet can be connected to the water tank 200 of the toilet (see Figure 1 ) is connected, and the outlet end of the water inlet is provided with a first water diversion port and a second water diversion port. The first water diversion port guides the water flow to the first flow channel 11 and flows out through the first washing circle outlet 111. The second water diversion port guides the water flow to the second flow channel 12 and flows out through the second washing circle outlet 121.

[0062] Furthermore, the washing ring 1 includes a washing ring bottom wall 13 and a washing ring side wall 14 arranged outside the washing ring bottom wall 13, the washing ring bottom wall 13 is connected to the upper edge of the pot surface 2, and a flow channel protrusion 15 is arranged on the washing ring bottom wall 13, the flow channel protrusion 15 is bent and extended, and the above-mentioned first flow channel 11 and second flow channel 12 are formed between the washing ring side wall 14.

[0063] See also Figure 3 and Figure 4 The pot surface 2 includes a first pot surface section 21 and a second pot surface section 22 connected end to end. The first pot surface section 21 is located at the front end of the toilet body 100. The first pot surface section 21 is recessed relative to the second pot surface section 22 to form a lower water tank 20. The lower water tank 20 is used to guide the first water flow to the water trap 3. By providing a more recessed first pot surface section 21 at the front end of the pot surface 2 to form the lower water tank 20, when the water flow output from the first washing ring water outlet 111 flows to the lower water tank 20, most of the water flows directly to the water trap 3 through the lower water tank 20, that is, the first water flow is the main water flow, the water volume is large, and the flow direction is directly from the front end of the pot surface 2 to the water surface at the water trap 3, so as to quickly form a siphon to flush away the dirt. Moreover, since the slope at the lower water trough 20 is greater than the slope at the second pot surface section 22, the first water flow at the lower water trough 20 can rush to the water trap 3 more quickly, further accelerating the water flow speed and quickly forming a siphon to discharge sewage.

[0064] Furthermore, the surfaces of the first pot surface section 21 and the second pot surface section 22 have no raised parts and are in an overall downward trend, thereby ensuring the water flow speed and avoiding the water flow speed being slowed down by the raised parts.

[0065] Exemplarily, the cross-sectional area of ​​the first wash ring water outlet 111 is twice or more than the cross-sectional area of ​​the second wash ring water outlet 121, so as to maximize the water volume of the first water flow.

[0066] In this embodiment, the first pot surface section 21 is within the angle range of α with the center of the pot surface 2 as the vertex, and the value range of α is 100° to 140°. The center of the pot surface 2 is the intersection of the symmetry line of the front-to-back direction of the pot surface 2 and the symmetry line of the left-to-right direction. The lower water trough 20 formed by the first pot surface section 21 within this angle range has a sufficiently large drainage area to ensure that the first stream of water has a large flow rate and ensure the flushing and sewage discharge effect. Moreover, the lower water trough 20 formed by the first pot surface section 21 within this angle range is not too large, resulting in all the water output from the outlet of the first pot surface 2 flowing through the lower water trough 20 to the water trap 3, and cannot be diverted to the second washing circle outlet 121 to form a third stream of water.

[0067] Exemplarily, the value of α is 100°, 110°, 120°, 130°, 140°, etc., but is not limited to the listed values. In this embodiment, the value of α is 120°.

[0068] Furthermore, the lower water tanks 20 are distributed on both sides of the center line M of the pot surface 2 .

[0069] The angle between the line connecting the highest point and the lowest point of the cross section of the first pot surface section 21 along the vertical plane and the horizontal plane is set to β, and the vertical plane is perpendicular to the front-to-back direction of the toilet. Figure 4 , the cross-section of the first pot surface section 21 along the vertical plane includes the cross-section at AA, the cross-section at BB, and the cross-section at CC. Among them, the value range of β is 10°~50°, and along the direction from top to bottom, the first pot surface section 21 tends to extend downward. The lower water trough 20 formed by the first pot surface section 21 within the above β angle range can ensure that the water flow has a sufficient water discharge speed. Further, the value range of β is 20°~40°.

[0070] It should be noted that the angle β at any cross section of the first pot surface section 21 may vary, and is limited to between 10° and 50°, and further limited to between 20° and 40°. Figure 5 , the angle β formed by the cross section at AA is 22°; see Figure 6 , the angle β formed by the cross section at BB is 26°; see Figure 7 , the β angle formed by the cross section at CC is 38°.

[0071] In this embodiment, the angle between the tangent line of the second pot surface section 22 at the uppermost end and the horizontal plane is γ, and the value range of γ is 2° to 10°, that is, the angle at which the second pot surface section 22 starts to fall is 2° to 10°. Exemplary values ​​are 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc., but are not limited to the listed values. Fig. 9 It shows Figure 8 In the cross-sectional view at DD, the angle γ between the tangent line of the second pot surface section 22 at the uppermost end and the horizontal plane is 5°. Fig.10 It shows Figure 8 In the cross-sectional view at EE, the angle γ between the tangent line of the second pot surface section 22 at the uppermost end and the horizontal plane is 5°. Fig.11 It shows Figure 8 In the cross-sectional view at point FF, the angle γ between the tangent line of the second pot surface section 22 at the uppermost end and the horizontal plane is 5°.

[0072] Furthermore, the angle between the tangent line of the first pot surface section 21 at the uppermost end and the horizontal plane is φ, φ>γ, so as to ensure that the first pot surface section 21 is concave relative to the second pot surface section 22, that is, the angle at which the first pot surface section 21 falls is greater than the angle at which the second pot surface section 22 starts to fall. Exemplarily, the value range of the angle φ is 15° to 50°, so as to ensure that the water flow has a faster falling speed at the lower water tank 20 formed by the first pot surface section 21. That is, the first water flow has both a sufficiently large flow rate and a faster water discharge speed.

[0073] In this embodiment, the projection area and aspect ratio of the pot surface 2, the water trap 3 and the water inlet 41 of the drainage bend 4 are limited. The orthographic projection area of ​​the pot surface 2 on the horizontal plane is set to S1, the orthographic projection area of ​​the water trap 3 on the horizontal plane is set to S2; the orthographic projection area of ​​the water inlet 41 of the drainage bend 4 on the horizontal plane is set to S3; the ratio of S1 to S2 is greater than or equal to 3 and less than or equal to 5, and the ratio of S2 to S1 is greater than or equal to 1 and less than or equal to 3, ensuring that the cross-sectional area of ​​the pot surface 2, the water trap 3 and the water inlet 41 of the drainage bend 4 is gradually reduced, while realizing the step-by-step acceleration of the water flow, it can also ensure that the flow rate of the first water flow reaches the maximum, and the water discharge speed is fast.

[0074] Further, see Fig.12 , it is stipulated that the front-to-back direction of the toilet is the first direction, and the left-to-right direction is the second direction, wherein the first direction is perpendicular to the second direction. The maximum dimension of the pot surface 2 in the first direction is L1, and the maximum dimension of the pot surface 2 in the second direction is L2, and the ratio of L1 to L2 is greater than or equal to 1.3 and less than or equal to 1.5; that is, the length-to-width ratio of the pot surface 2 ranges from 1.3 to 1.5. The maximum dimension of the water trap 3 in the first direction is L3, and the maximum dimension of the water trap 3 in the second direction is L4, and the ratio of L3 to L4 is greater than or equal to 1.1 and less than or equal to 1.3; that is, the length-to-width ratio of the water trap 3 ranges from 1.1 to 1.3. The maximum dimension of the water inlet 41 of the drainage bend 4 in the first direction is L5, and the maximum dimension of the water inlet 41 of the drainage bend 4 in the second direction is L6, and the ratio of L5 to L6 is greater than or equal to 1 and less than or equal to 1.1; that is, the length-to-width ratio of the water inlet 41 of the drainage bend 4 ranges from 1 to 1.1. The limitation of the length-to-width ratio of the above-mentioned pot surface 2, water trap 3 and water inlet 41 of the drainage bend 4 makes the cross-sectional shape of the pot surface 2, water trap 3 and water inlet 41 of the drainage bend 4 more reasonable, avoids the cross-sectional shape from being an overly slender structure, and maximizes the flow rate of the first water flow with a faster discharge speed.

[0075] In this embodiment, the limitations on the projected area and the aspect ratio of the pot surface 2, the water trap 3 and the water inlet 41 of the drainage bend pipe 4 help to maximize the flow rate of the first water flow and enable the first water flow to have a faster discharge speed, thereby increasing the flushing force and speed of the toilet and improving the sewage discharge performance.

[0076] For example, the pot surface 2 has a length-to-width ratio of 1.4, the trap 3 has a length-to-width ratio of 1.2, and the water inlet 41 of the drain bend 4 has a length-to-width ratio of 1.1. The projected area ratio of the pot surface 2 to the trap 3 is 4.2, and the projected area ratio of the trap 3 to the water inlet 41 of the drain bend 4 is 2.1.

[0077] Furthermore, in the present embodiment, the distance between the front end of the water trap 3 and the front end of the pot surface 2 is L7, and the distance between the water inlet 41 of the drainage bend 4 and the front end of the pot surface 2 is L8. Exemplarily, L7 is 200 mm, and L8 is 250 mm. This can maximize the amount of water in the first water flow that falls from the front end of the pot surface 2 to the water trap 3, and enable the first water flow to hit the water inlet 41 of the drainage bend 4 faster, thereby increasing the speed of siphon formation, accelerating the flushing speed and sewage discharge effect.

[0078] See also Fig.13 There is a first dividing line 5 between the water trap 3 and the pot surface 2, the first dividing line 5 is set at an angle to the horizontal plane, and the rear end of the first dividing line 5 is higher than the front end of the first dividing line 5. In other words, the lowest point of the rear end of the pot surface 2 is higher than the lowest point of the front end of the pot surface 2, so that the sinking amount of the front end of the pot surface 2 is greater, so that the area of ​​the lower water tank 20 at the front end of the pot surface 2 is larger, and the flow rate of water (i.e., the first water flow) at the lower water tank 20 is further increased and the flow rate of the water flow at the front end of the pot surface 2 is accelerated, and at the same time, the first water flow is prevented from rushing out of the pot surface 2 to cause splashing.

[0079] Furthermore, there is a second dividing line 6 between the water trap 3 and the drainage bend 4, the second dividing line 6 is set at an angle with the horizontal plane, and the rear end of the second dividing line 6 is higher than the front end of the second dividing line 6. That is, the water inlet 41 of the drainage bend 4 is inclined relative to the horizontal plane and inclined toward the lower water tank 20 at the front end of the pot surface 2, so that the water inlet 41 of the drainage bend 4 can better receive the first water flow from the lower water tank 20, and fully utilize the potential energy of the first water flow to flush away dirt.

[0080] Exemplarily, the angle between the first dividing line 5 and the horizontal plane is θ, and the value range of θ is 5° to 15°. For example, the value of θ is 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc., but not limited to the listed values. The angle θ within this angle range can ensure that the lowest point of the front end of the pot surface 2 is low to form a lower water tank 20 with a larger area, and can also avoid the lowest point of the front end of the pot surface 2 being too low, preventing the unreasonable structural phenomenon of the front end of the water trap 3 being too low and the rear end being too high, and avoiding the first stream of water from being too large in potential energy and causing impact splashing. The angle between the second dividing line 6 and the horizontal plane is Ψ, and the value range of Ψ is 5° to 15°. For example, the value of Ψ is 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc., but not limited to the listed values. The values ​​of θ and Ψ can be the same or different. The angle Ψ within this angle range can ensure that the first stream of water flowing down from the lower trough 20 is better received, and the potential energy of the first stream of water is fully utilized to flush away dirt, and the water inlet 41 of the drain elbow 4 is not too inclined to cause water splashing out.

[0081] In this embodiment, the second dividing line 6 is approximately parallel to the first dividing line 5 , so that the entire water trap 3 is inclined relative to the horizontal plane, ensuring that a larger area at the front end of the pot surface 2 can form the lower water trough 20 .

[0082] The present embodiment also provides a non-main flush silent rotary flush toilet, comprising a water tank 200 and the toilet body 100 as described above, wherein the water tank 200 is disposed on the toilet body 100 (see Figure 1 ), and can be connected with the first washing circle water outlet 111 and the second washing circle water outlet 121 through the water inlet 10 on the washing circle 1.

[0083] The main-flush-free silent rotary flush toilet including the toilet body 100 as described above, when flushing, water is discharged through the first wash ring water outlet 111 and the second wash ring water outlet 121 on the wash ring 1, and the water flow flowing out of the first wash ring water outlet 111 flows along the circumference of the wash ring 1 to the front end of the pot surface 2, and is divided at the front end of the pot surface 2, so that a part of the water flow flows downstream along the front end of the pot surface 2 to form a first water flow, and the first water flow directly enters the water trap 3; the water flow flows out of the second wash ring water outlet 111 to the front end of the pot surface 2, and the water flow flows out of the first ... The water flowing out of 21 flows along the circumference of the washing ring 1 to the first washing ring water outlet 111, and converges with the water flowing out of the first washing ring water outlet 111 near the first washing ring water outlet 111 to form a second water flow; another part of the water flow diverted at the front end of the pot surface 2 passes over the front end of the pot surface 2 and continues to flow until it reaches the second washing ring water outlet 121, and converges with the water flowing out of the second washing ring water outlet 121 near the second washing ring water outlet 121 to form a third water flow. That is, when the toilet body 100 is flushed, a water flow is formed at the first washing ring water outlet 111, the second washing ring water outlet 121 and the front end of the pot surface 2. The first water flow, the second water flow and the third water flow formed eventually rotate into the water trap 3 and the drainage bend pipe 4, and the waste is discharged by siphoning through the drainage bend pipe 4. Since the cross-sectional area of ​​the water trap 3 is smaller than the cross-sectional area of ​​the pot surface 2, and the cross-sectional area of ​​the drainage bend 4 is smaller than the cross-sectional area of ​​the water trap 3, the water flow can accelerate the rotation at the water trap 3 and further accelerate at the inlet end of the drainage bend 4 to quickly discharge the waste. The toilet provided in the embodiment of the present application forms three streams of water for flushing, and the main flushing hole at the bottom of the toilet bowl can be eliminated. Compared with the toilet in the prior art that flushes by jetting through the main flushing hole, the flushing noise can be effectively reduced.

[0084] More importantly, the flow rate of the first water flow formed is greater than the flow rate of the second water flow, and greater than the flow rate of the third water flow, that is, the water flow that flows to the front end of the pot surface 2 and directly flows to the water trap 3 at the front end of the pot surface 2 has the largest flow rate. By increasing the flow rate of the first water flow, the flushing water flow can rush to the water inlet 41 of the drainage bend pipe 4 faster and more fully, thereby increasing the flushing force and water flow speed, and enabling the drainage bend pipe 4 to form a siphon faster to discharge sewage. The first water flow with a large flow rate has a large potential energy, which can improve the flushing ability, ensure that the sewage is flushed away, and improve the flushing speed and sewage discharge performance of the toilet.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
