A toilet structure

Abstract

A toilet structure of the present invention includes a lower flushing part and an upper flushing part. The lower flushing part includes a front extension part, relatively arranged rear extension parts, and a siphon part. The front extension part includes an extension pipe that accommodates the water seal water and is arranged between the front extension part and the rear extension parts. The siphon part includes a sewage collection part arranged below the water outlet of the lower nozzle and along the siphon port. The height of the sewage collection part is lower than the height of the convex corner and the front extension wall. A siphon port is arranged at one end of the sewage collection part far from the lower nozzle. In the present invention, the sewage collection part and the rear extension wall are moved to a more rearward and lower position, so that the dirt discharged by the user will fall to the right side of the vertical tangent of the lower edge of the rear wall, that is, the bottom of the entire toilet, increasing the space for accommodating dirt. When flushing the dirt, the activity space of the dirt and the water flow is large, and there will be no phenomenon of blocking and splashing. The siphon effect is stronger, and it can adapt to lower water supply pressure, improving the practicability of the toilet.

Description

Technical Field

[0001] The present invention relates to a toilet structure, in particular to a pressure jet siphon toilet structure. Background Art

[0002] A pressure jet siphon toilet adds a jet secondary channel at the bottom inside the toilet, aiming at the center of the sewage outlet. When flushing, part of the water flows out along the rim wash, and part is ejected from the jet orifice. This kind of toilet uses a relatively large water flow force to generate siphon to quickly flush away the dirt.

[0003] Traditional toilet structures such as Figure 7 , in the traditional structure, the inventor has found the following problems through long-term thinking and a large number of practices:

[0004] 1. When flushing, the lower spray water flow ejected by the lower nozzle is likely to collide with the ceramic surface, resulting in an increased flow resistance of the water flow, and the flowing distance of the jet water flow is far, the flowing direction of the water flow does not correspond to the position of the siphon port, the generated siphon effect is poor, and the utilization rate of the water flow is low.

[0005] 2. When flushing, due to the narrow position of the dirt collection area, the dirt is easily blocked when the lower jet water flow ejects, and it is easy to splash onto the user's buttocks, affecting the user's perception of the toilet.

[0006] 3. Under a relatively low pressure, such as above about 0.1 MPa, siphon can be generated, and the siphon diameter is small, which is easy to cause blockage for household use, the sewage discharge capacity is poor, and the toilet needs to be cleaned frequently, affecting the use of consumers.

[0007] For another toilet structure, such as in Japanese Patent Application No.: 03822732.0, the landing point of the dirt in this toilet will fall on the ceramic surface, which is easy to cause the phenomenon of feces sticking. When discharging sewage, the upper water flow impact force is insufficient, which is likely to cause part of the dirt to remain on the ceramic surface. After flushing, there is still part of the residue, and it needs to be washed and flushed many times, which is rather troublesome. Summary of the Invention

[0008] The present invention provides a toilet structure, which can effectively solve the above problems.

[0009] The present invention is realized as follows:

[0010] A toilet structure includes: a lower flushing part, an upper flushing part, the lower flushing part includes a front extension part, rear extension parts arranged oppositely, and a siphon part,

[0011] The front extension part includes an extension pipe that holds the seal water and is set in the middle of the front extension part and the rear extension part. The extension pipe is inclined and set behind the bottom of the urinal. One end close to the lower spray head is fixedly connected with a front extension wall. There is an integrally formed convex corner for guiding the water flow between the front extension wall and the lower spray head. The upper spray head swirls and converges into the extension pipe that is inclined downward and backward. After turning backward through the convex corner and merging with the pressurized water of the lower spray head, the water and dirt are sucked away through the siphon phenomenon at the siphon part.

[0012] The rear extension part has a rear extension wall set at the relative position of the front extension wall. One side of the rear extension wall close to the siphon part is fixedly connected with a siphon mouth edge, and one end far from the siphon mouth edge is integrally formed with a lower rear wall edge.

[0013] The siphon part includes a dirt collection part set below the water outlet of the lower spray head and the siphon mouth edge. The height of the dirt collection part is lower than the height of the convex corner and the front extension wall. One end of the dirt collection part far from the lower spray head is provided with a siphon mouth. The pressurized water output by the lower spray head sucks and collects the swirl flowing from the upper flushing part through the Venturi effect and reaches the siphon mouth. The water and dirt at the siphon mouth pass through the rising passage to the weir part to generate a siphon phenomenon, and then the dirt is discharged through the vertical pipe.

[0014] The convex corner is set above the water outlet of the lower spray head to separate the upper and lower water flows, facilitating the lower spray head to generate a suction effect to suck away the swirl of the upper spray head.

[0015] The lower convex end of the siphon mouth edge is higher than the jet channel of the lower spray head.

[0016] As a further improvement, the upper flushing part includes an annular water channel connected to the water outlet of the upper spray head. Below the annular water channel is a dry surface, and below the dry surface is integrally formed a water accumulation surface. The water accumulation surface is connected to the extension pipe. The pressurized water from the upper spray head flows through the annular water channel. Some of the oblique flow and the flowing water clean the dry surface and then lift the seal water of the water accumulation surface. The water is introduced into the extension pipe through the water accumulation surface to increase the pressure of the pressurized water of the lower spray head.

[0017] As a further improvement, both the lower spray head and the upper spray head communicate with the water control part. The water control part includes a first water supply part connected to the upper spray head through a pipe and a second water supply part connected to the lower spray head through a pipe. Both the first water supply part and the second water supply part communicate with the water inlet end through control valves.

[0018] As a further improvement, the lower spray head is inclined and set at the water inlet of the lower flushing part to connect to the external pressurized water. The jet of the lower spray head can directly spray to three - quarters of the height from the bottom to the top of the rising passage.

[0019] As a further improvement, the flow path for the dirt to be discharged between the lower rear wall edge, the rear extension wall, the upper and lower parts of the siphon mouth, the front extension wall, the convex corner, and the rising passage is greater than 50mm.

[0020] As a further improvement, the dirt collection part is arranged at the lower half of the right end of the vertical tangent of the convex edge along the lower edge of the rear wall, and the vertical tangent of the lower edge of the rear wall and the vertical tangent of the convex corner are on the same straight line.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention moves the dirt collection part and the rear extension wall to a more rear and lower position, so that the dirt discharged by the user will fall to the right side of the vertical tangent of the lower edge of the rear wall, that is, the bottom of the entire toilet bowl, increasing the space for accommodating dirt. When flushing the dirt, the activity space of the dirt and the water flow is large, and there will be no blocking and splashing phenomena. Moreover, since the dirt no longer impacts the ceramic surface during flushing, the noise during flushing is reduced, improving the practicality of the toilet.

[0023] 2. The present invention sets the position of the extension pipe between the front extension wall and the rear extension wall lower and more inclined, enabling the swirling effect of the upper water flow from the upper spray head to be stronger, the flushing potential energy to be greater, and the water flow force impacting in the dirt collection part to be stronger, providing a greater and faster water flow velocity for washing away the dirt.

[0024] 3. The position of the siphon port is set on the right side of the dirt collection part, which is more rear and lower compared with the prior art. The upper water flow from the upper spray head and the lower water flow from the lower spray head converge at the siphon port. And based on the "Venturi effect" generated by the lower spray head, when the lower spray head jets to the rising passage, it will produce a suction effect on the upper water flow from the upper spray head, causing the upper water flow from the upper spray head and the dirt collection part to be suctioned to the siphon port to generate siphon. The siphon effect is stronger, and a strong siphon effect can also be generated when the flow pressure in the toilet bowl is about 0.05 MPa.

[0025] 4. The convex corner is blocked at the convergence of the upper water flow and the lower water flow to prevent the upper water flow from affecting the jet of the lower water flow after flushing downward. By means of the convex edge of the convex corner, the upper water flow and the lower water flow can be guided to converge, forming a stronger siphon water flow.

[0026] 5. The lower edge of the rear wall and the rear extension wall are retracted into the interior of the toilet bowl compared with the prior art, not only reducing the area of direct contact with dirt, preventing dirt from sticking to it and increasing the difficulty of flushing, but also increasing the accommodation space for dirt, being able to accommodate more dirt and preventing blockage.

[0027] 6. The lower convex end of the siphon port edge is higher than the jet channel of the lower spray head, which will not hinder the jet channel of the lower spray head and reduce the flow resistance of the lower water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] To make the implementation modes of the present invention, all fall within the scope of protection of the present invention. Therefore, the following detailed description of the implementation modes of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected implementation modes of the present invention. Based on the implementation modes in the present invention, all other implementation modes obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0047] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0048] Refer to Figure 1-7 As shown, a toilet structure includes: a lower flushing part 50, an upper flushing part 10. The lower flushing part 50 includes a front extension part 51, relatively arranged rear extension parts 52, and a siphon part 53.

[0049] The front extension part 51 includes an extension pipe 511 that accommodates the water seal water and is arranged between the front extension part 51 and the rear extension part 52.

[0050] The extension pipe 511 is inclined and arranged at the rear of the bottom of the toilet bowl 60. One end close to the lower nozzle 40 is fixedly connected with a front extension wall 510. A convex angle 512 for guiding the water flow is integrally formed between the front extension wall 510 and the lower nozzle 40. The upper nozzle 20 swirls and converges to the downward and backward inclined extension pipe 511. After turning backward through the convex angle 512, it merges with the pressurized water of the lower nozzle 40, and then the dirt is sucked away through the siphon phenomenon at the siphon part 53.

[0051] The rear extension part 52 is provided with a rear extension wall 521 at a position opposite to the front extension wall 510. One side of the rear extension wall 521 close to the siphon part 53 is fixedly connected with a siphon port edge 522, and a rear wall lower edge 520 is integrally formed at one end far from the siphon port edge 522.

[0052] The siphon part 53 includes a sewage collection part 533 disposed at the water outlet of the lower spray head 40 and below the siphon mouth edge 522. The height of the sewage collection part 533 is lower than the heights of the convex corner 512 and the front extension wall 510. One end of the sewage collection part 533 away from the lower spray head 40 is provided with a siphon mouth 534. The pressurized water output by the lower spray head 40 sucks and collects the swirling flow collected from the upper flushing part 10 by the Venturi effect through the extension pipe 511 to reach the siphon mouth 534. The water and dirt at the siphon mouth 534 reach the weir part 531 through the rising passage 530 to generate a siphon phenomenon, and then the dirt is discharged through the vertical pipe 532.

[0053] The convex corner 512 is disposed above the water outlet of the lower spray head 40 to separate the upper and lower water flows, facilitating the lower spray head 40 to generate a suction effect to suck away the swirling flow of the upper spray head 20, and preventing the upper water flow from hindering the jet flow of the lower water flow during downward flushing, so that the two do not affect each other.

[0054] The lower convex end of the siphon mouth edge 522 is higher than the jet flow channel of the lower spray head 40 and will not hinder the jet flow channel of the lower spray head 40.

[0055] Further, the upper flushing part 10 includes an annular water channel 11 connected to the water outlet of the upper spray head 20. A drying surface 12 is disposed below the annular water channel 11. A water accumulation surface 13 is integrally formed below the drying surface 12. The water accumulation surface 13 is connected to the extension pipe 511. The pressurized water from the upper spray head 20 flows through the annular water channel 11. Part of the oblique flow and the flowing water clean the drying surface 12 and then lift the water seal water of the water accumulation surface 13. The water is introduced into the extension pipe 511 through the water accumulation surface 13 to increase the pressure of the pressurized water of the lower spray head 40.

[0056] Further, both the lower spray head 40 and the upper spray head 20 are communicated with the water control part 30. The water control part 30 includes a first water supply part 31 connected to the upper spray head 20 through a pipeline, and a second water supply part 33 connected to the lower spray head 40 through a pipeline. Both the first water supply part 31 and the second water supply part 33 are communicated with the water inlet end 32 through control valves. The lower spray head 40 is a Venturi tube and can generate a certain suction force on the water seal water of the extension pipe 511 when spraying the lower water flow, providing a certain boost for the water seal water of the extension pipe 511 and the swirling flow from the upper spray head 20, so that the water from above can flow in faster and converge with the lower water flow.

[0057] Further, the lower spray head 40 is inclined and disposed at the water inlet of the lower flushing part 50 to receive external pressurized water. The jet flow of the lower spray head 40 can directly spray to three-quarters of the height from the bottom up of the rising passage 530. The height of the jet flow flushing will neither directly exceed the weir part 531 resulting in excessive impact force, nor can it flush the dirt to a relatively high height to improve the siphon effect.

[0058] Further, the flow path for dirt discharge between the lower edge 520 of the rear wall, the rear extension wall 521, the upper half and the lower half of the front extension wall 510, the convex corner 512, and the rising passage 530 is greater than 50 mm.

[0059] Further, the dirt collection part 533 is arranged at the lower half of the right end of the vertical tangent of the convex edge of the lower edge 520 of the rear wall. The vertical tangent of the lower edge 520 of the rear wall and the vertical tangent of the convex corner 512 are on the same straight line. By arranging the dirt collection part 533 in a lower and more rear position, the effect of hiding dirt is better, and even when splashing occurs, it can be blocked by the rear extension wall 521 and the edge 522 of the siphon mouth in time.

[0060] The process of dirt excretion and flushing of the toilet:

[0061] When the user excretes, the dirt falls onto the front extension wall 510 due to gravity and slides into the dirt collection part 533 along the inclined extension pipe 511. Moreover, the dirt collection part 533 is arranged in a lower and more rear position and is blocked by the edge 522 of the siphon mouth. When splashing occurs, the dirt will not splash onto the user's buttocks;

[0062] When flushing, the pressurized water is connected from the water inlet end 32, sprayed from the upper spray head 20 through the first water supply part 31, and circulates around the annular water channel 11 to clean the outermost circle. When circulating, part of the water flow will swirl along the dry surface 12 to form a vortex-shaped water flow. When swirling on the dry surface 12, part of the water flow will swirl along the water accumulation surface 13 again. At this time, the height of the water seal water rises, and part of the water flows into the vertical pipe along the weir part 531;

[0063] At the same time, a stream of pressurized water is connected through the second water supply part 33 to the inclined lower spray head 40. The lower spray head 40 forms a jet along the rising passage 530, pushes the dirt in the dirt collection part 533 along the rising passage 530, and at the same time, the lower spray head 40 generates a Venturi effect, sucking the water seal water of the extension pipe 511 and the swirling water flow from the upper flushing part 10, so that the two converge with the downward water flow at a faster speed and rush along the rising passage 530 to the weir part 531 to generate siphon, and flush the dirt and all the water out along the weir part 531 and the vertical pipe 532 until there is no remaining dirt and water in the siphon mouth 534 and the dirt collection part 533. Then, the upper spray head 20 flows down from the annular water channel 11, the dry surface 12, and the water accumulation surface 13 in turn according to the flow path during flushing, and is stored in the water accumulation surface 13, the extension pipe 511, the dirt collection part 533, and the middle section of the rising passage 530 to form a water seal water surface, waiting for the next excretion process.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
