Description

Technical Field

[0001] The invention belongs to the technical field of flush toilets used for flushing toilets, and in particular relates to a siphon toilet. Background Art

[0002] Traditional siphonic toilets, after flushing the water tank, rely on the gravity of the water flow and the suction effect formed by the siphon structure of the toilet itself to pump the waste into the sewer, completing the entire flushing and sewage discharge process. The existing technology for toilet research focuses on two aspects: 1) How to improve the flushing effect of the inner surface of the pot body, such as my country's patents CN220888854U, CN203080674U and CN112211260A; 2) How to increase the thrust of the water flow at the bottom of the pot during siphoning and the suction of the sewage pipe on the miso, so as to avoid blockage of the sewage outlet and increase the sewage discharge volume, such as my country's patents CN112211260A, CN104712045B and CN110016951A.

[0003] The existing siphon toilets have the following problems: 1. In order to increase the water flow rate into the sewage pipe, the injection holes set at the top of the pot bottom cap increase the hole structure of the pot bottom, and the miso pollutes the hole mouth, resulting in many sanitary dead corners in the pot bottom, which is not easy to clean; 2. The strong water flow from the injection hole rushes in parallel with the sewage pipe mouth, pushing the sewage to flow directly at high speed in the pipe under high pressure. The miso contacts the inner wall of the sewage pipe and is also prone to adhesion, and the direct water cannot fully carry away the adhesion. In addition, the siphon pipe is a large-turn bend pipe. Under the action of centrifugal force, the impact of the water flow on the back water side wall is much smaller than the flushing force on the front water side wall. Therefore, it is common to see that miso residues are easily accumulated on the lower side of the bend. Summary of the invention

[0004] The technical problems to be solved by the present invention are the problem of multiple cleaning dead corners at the bottom of a pot and the problem of residue accumulation inside a sewage pipe.

[0005] The present invention solves the above-mentioned problem by adopting the following technical solution: A dazzling siphonic toilet comprises a pot body with an opening at the top, a seat ring is arranged on the top of the pot body, the lower end of the front side wall of the pot body is connected to the hat head, the lower end of the rear side wall of the pot body extends to the upper part of the rear end of the hat head to form a baffle, the rear end of the hat head is connected to the siphon sewage pipe to form a water trap, an upper water channel is arranged above the siphon sewage pipe, the rear end of the upper water channel is connected to the drain hole of the water tank, a first flushing water channel is arranged on the back of the rear side wall of the pot body, the upper end of the first flushing water channel is connected to the upper water channel, the lower end extends to the water trap position and enters tangentially from the water trap, and the lower mouth of the first flushing water channel is located below the water cover surface.

[0006] Compared with the prior art, the present invention adopting the above structure has the following beneficial effects: 1) In this scheme, there are no other holes in the pot body except the drainage hole at the cap head, reducing the cleaning dead corners; 2) The spray hole in the pot is eliminated, thereby reducing noise; 3) In this scheme, water is introduced from the side of the pipe to form a rotating water flow that can roll back along the pipe wall. The water flow continues to rotate in the pipe with the rotational potential energy. Due to the siphon effect formed by the pipe, a rotating flow is formed in the pipe, thereby forming a scouring on the inner wall of the siphon drainage pipe. The inner wall of the pipe has no back water surface, thereby achieving a complete flushing effect.

[0007] As a preferred embodiment, a further technical solution of the above structure is: The lower end of the first flushing water channel tilts to the left or right and cuts in from the top wall side of the siphon sewage pipe inlet, or the lower part of the first flushing water channel bends to the left or right and cuts in from the side wall of the water trap.

[0008] Beneficial effects obtained from the above features: This embodiment enables the flushing water to have centrifugal force when it dives downward from the first flushing water channel. The water flow guided by the first flushing water channel rushes in from the side wall of the water trap, forming a strong vortex, which has a greater impact on the pipe wall.

[0009] The rear side wall of the pot body closes toward the center, so that the lower end of the first flushing water channel is inclined toward the front end.

[0010] The beneficial effects obtained by the above features are as follows: in this example, the rotational potential energy of the water flow is more inclined toward the pot body side, and the water flow has a strong scouring effect on the bottom of the pot.

[0011] The lower end of the rear side wall of the pot body is bent backwards, so that the lower end of the first flushing water channel is tilted backwards.

[0012] Beneficial effects obtained from the above features: This example makes the water flow rotation potential energy closer to the siphon sewage pipe side, mainly focusing on pipe flushing.

[0013] The lower outlet of the first flushing water channel corresponds to the middle section of the trap.

[0014] Beneficial effects obtained by the above features: This example increases the flow rate ratio distributed to the pot body.

[0015] The lower outlet of the first flushing water channel corresponds to the rear section of the trap.

[0016] Beneficial effects obtained by the above features: This example increases the amount of water distributed to the siphon drain pipe and strengthens flushing in the pipe.

[0017] A second flushing water channel is also provided, which is arranged inside the seat ring, one end of which is connected to the upper water channel, and the other end extends toward the front end of the pot body along one side of the seat ring close to the first flushing water channel, and a circle water hole is provided at the end, and the circle water hole faces the front end of the pot body.

[0018] Beneficial effects obtained from the above features: In this example, rotational potential energy is formed by the circle water, and the flushing water poured into the siphon sewage pipe further energizes it.

[0019] In this scheme, the water flow that enters the hat head tangentially downward forms an upward rotating water flow, which is connected to the pot body and the siphon sewage pipe through the two ends of the hat head respectively, so that the rotating water flow is diverted to the direction of the pot body and the sewage pipe. The part of the water flow diverted to the siphon sewage pipe continues to rotate in the pipe with the rotating potential energy, and the siphon effect formed by the pipe forms a rotating flow in the pipe; the part of the water flow diverted to the pot body forms a rotating flushing at the bottom of the pot, thereby flushing the bottom of the pot, and then the funnel shape of the pot bottom and the siphon effect are used to make the rotating water flow move downward and backflow to the sewage pipe, so that the flushing water in the siphon sewage pipe forms a flushing, and the inner wall of the pipe has no back water surface, thereby achieving a complete flushing effect.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0022] See also Figures 1 to 4 The Xuanchong siphon toilet provided by the present invention includes a pot body 4 with an opening at the top, a seat ring 5 is provided on the top of the pot body 4, the lower end of the front side wall 6 of the pot body is connected to the cap head 8, the lower end of the rear side wall 3 of the pot body extends to the upper part of the rear end of the cap head 8 to form a baffle 7, the rear end of the cap head 8 is connected to the siphon sewage pipe 10 to form a water trap 9, an upper water channel 1 is provided above the siphon sewage pipe 10, the rear end of the upper water channel 1 is connected to the drain hole of the water tank, a first flushing water channel 2 is provided on the back of the rear side wall 3 of the pot body, the upper end of the first flushing water channel 2 is connected to the upper water channel 1, the lower end extends to the position of the water trap 9 and enters tangentially from the water trap 9, and the lower mouth of the first flushing water channel 2 is located below the water cover surface.

[0023] In this solution, the lower opening of the first flushing water channel 2 is located behind the baffle 7 and is designed as a hidden structure. Except for the lower sewage outlet, no other holes are visible on the pot body 4, thereby reducing the blind spots for cleaning and facilitating cleaning by users. On the one hand, this structure can focus more water on flushing the sewage outlet and directly take away the adhesions, reducing the accumulation of dirt; on the other hand, when the user manually scrubs, only one hole needs to be cleaned, which is more convenient. For more details, see Figure 1 In the example shown, the connection point A between the rear wall of the first flushing water channel 2 and the upper wall of the siphon drain pipe 10 is slightly higher than the lower end point B of the baffle 7. In this example, the rear side wall 3 of the pot body is also the front wall of the first flushing water channel 2.

[0024] The existing toilet with a secondary water channel jet hole usually generates a lot of noise. The present solution eliminates the jet hole in the pot, making it quieter.

[0025] In this solution, water is introduced into the pipe from the side to form a rotating water flow that can roll back along the pipe wall. The water flow continues to rotate in the pipe with the rotational potential energy. Due to the siphon effect formed by the pipe, a rotating flow is formed in the pipe, thereby forming a flushing on the inner wall of the siphon sewage pipe 10. The inner wall of the pipe has no back water surface, thereby achieving a complete flushing effect.

[0026] As an option, the lower end of the first flushing water channel 2 is inclined to the left or right, cutting into the side of the top wall of the inlet of the siphon sewage pipe 10, or the lower part of the first flushing water channel 2 is bent to the left or right, cutting into the side wall of the water trap 9. The first flushing water channel 2 of this shape makes the flushing water have centrifugal force when it dives downward from the first flushing water channel 2. The water flow guided by the first flushing water channel 2 rushes into the water trap 9, forming a strong vortex, which has a greater impact on the pipe wall (including the pipe wall of the water trap 9 and the pipe wall of the siphon sewage pipe 10).

[0027] As an option, the rear side wall 3 of the pot body closes toward the center, so that the lower end of the first flushing water channel 2 tilts toward the front end. As another option, the lower end of the rear side wall 3 of the pot body bends backward, so that the lower end of the first flushing water channel 2 tilts backward. The impulse inherited in the direction of the potential energy is large, the dirt at the bottom of the pot is heavy, and the flushing of the sewage pipe is also the main purpose of this scheme. Therefore, it is necessary to study the technical point of reasonable distribution of potential energy. The forward-tilted example makes the water flow rotation direction closer to the pot body 4, mainly focusing on the flushing of the bottom of the pot; the backward-bent example makes the water flow rotation direction closer to the siphon sewage pipe 10, mainly focusing on the flushing of the pipeline.

[0028] As an option, the lower opening of the first flushing water channel 2 corresponds to the middle section of the water trap 9 ; as another option, the lower opening of the first flushing water channel 2 corresponds to the rear section of the water trap 9 .

[0029] Due to the shape of the bottom surface of the water trap 9 and the structure of the baffle 7, a large part of the water discharged from the first flushing water channel 2 enters the siphon drain pipe 10, and a small amount goes to the bottom of the pot for flushing. It is also necessary to reasonably distribute the water according to the model and shape of the toilet. The example facing the middle section makes the water flow distributed to the pot body 4 and the siphon drain pipe 10 balanced, and the example facing the rear section increases the water amount distributed to the siphon drain pipe 10, thereby strengthening the flushing in the pipeline.

[0030] As a further improvement of this solution, a second flushing water channel 11 is also provided, which is arranged inside the seat ring 5, one end of which is connected to the upper water channel 1, and the other end extends to the front end of the pot body 4 along the side of the seat ring 5 close to the first flushing water channel 2, and a circle water hole 12 is provided at the end, and the circle water hole 12 faces the front end of the pot body 4. This solution adopts the structure of the circle channel vortex to cooperate with the function of the first flushing water channel 2 of this solution. On the one hand, the structure has a better flushing performance on the pot surface, and on the other hand, the circle hole vortex is designed to be designed in the same direction as the vortex at the bottom of the pot, so as to use the potential energy of the circle channel water vortex to further energize the flushing water of the siphon sewage pipe 10, achieving the effect of one plus one being greater than two.

[0031] Furthermore, the horizontal plane projection position of the lowest point of the water trap 9 is located behind the lower end of the baffle 7. This solution can make the miso fall to the rear side of the lower opening of the pot body 4 after falling into the pot body 4, so that it is more easily carried away by the vortex.

[0032] Beneficial effects of the present invention: This solution designs a water flow that enters the water trap tangentially to form an upward rotating water flow, and the two ends of the water trap are connected to the pot body and the siphon sewage pipe respectively, so that the rotating water flow is diverted to the direction of the pot body and the sewage pipe. Part of the water flow diverted to the siphon sewage pipe continues to rotate in the pipe with rotational potential energy, and a rotating flow is formed in the pipe due to the siphon effect formed by the pipe; part of the water flow diverted to the pot body forms a rotating flushing at the bottom of the pot, thereby flushing the bottom of the pot, and then the funnel shape of the pot bottom and the siphon effect are used to make the rotating water flow downward and backflow to the sewage pipe.

[0033] In this solution, water from the first flushing water channel and water from the second flushing water channel are quickly poured into the water trap. When the water discharge is about to end, water passes through the top of the siphon pipe and siphoning occurs. At this time, the water in the water trap still maintains a strong rotation. Under the action of the siphon, the swirling water is pulled backward, and the water moves backward in a spiral with the swirling potential energy, thereby forming a flushing in the siphon sewage pipe. The inner wall of the sewage pipe has no back water surface, thereby achieving a complete flushing effect.

[0034] The above description is only a preferred feasible embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made using the contents of the present specification and its drawings are included in the scope of rights of the present invention.
