Description

Technical Field

[0001] The utility model belongs to the technical field of flush toilets, in particular to a toilet with rotary flushing and sewage discharge. Background Art

[0002] Traditional siphonic toilets, after flushing the water tank, rely on the gravity of the water flow and the suction created by the siphon structure of the toilet itself to pump waste into the sewer, completing the entire flushing and sewage discharge process. Existing research on toilets focuses on two aspects: 1) How to improve the flushing effect of the inner surface of the pot body, such as Chinese 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 force of the sewage pipe on the miso, so as to avoid blockage of the sewage outlet and increase the sewage discharge volume, such as Chinese patents CN112211260A, CN104712045B and CN110016951A.

[0003] Problems with existing siphonic toilets: 1. In order to increase the flow rate of water flushing 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 contaminates the hole openings, resulting in many sanitary dead corners in the pot bottom, which is difficult to clean; 2. The strong water flow from the injection holes rushes in parallel with the pipe opening of the sewage pipe, pushing the sewage to flow directly at high speed in the pipe under high pressure. The miso is also prone to adhesion when it contacts the inner wall of the sewage pipe, and the straight water cannot fully carry away the adhesions. 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 miso residues easily accumulate on the lower side of the bend. Utility Model Content

[0004] The technical problems to be solved by the utility model 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 utility model solves the above problems by adopting the following technical solutions:

[0006] A rotary flush toilet comprises an open-top pot body, a seat ring provided on the top of the pot body, a cap head connected to the lower end of the front side wall of the pot body, a baffle extending above the rear end of the cap head, a siphon drain pipe connected to the rear end of the cap head to form a trap, a water channel provided above the siphon drain pipe, a rear end of the water channel connected to a drain hole of a water tank, and further comprising:

[0007] The 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 opening of the first flushing water channel is located below the water cover;

[0008] The second flushing water channel 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 the side of the seat ring close to the first flushing water channel, with a water outlet hole at the end.

[0009] Compared with the prior art, the present invention adopting the above structure has the following beneficial effects:

[0010] This solution is designed to have water flow that enters the trap tangentially, forming an upward rotating water flow. The two ends of the trap are connected to the pot body and the siphon sewage pipe respectively, so that the rotating water flow is diverted to 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 the rotational potential energy, and the siphon effect formed by the pipe forms a rotating flow in the pipe; part of the water flow diverted to the pot body forms a rotating flushing at the bottom of the pot, thereby dazzling 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 into the sewage pipe.

[0011] As a preferred embodiment, a further technical solution of the above structure is:

[0012] The lower end of the first flushing water channel tilts left or right and cuts into the side of the top wall of the siphon sewage pipe inlet, or the lower part of the first flushing water channel bends left or right and cuts into the side wall of the water trap.

[0013] The beneficial effects obtained by the above features are as follows: this embodiment enables the flushing water to have centrifugal force when it dives downward from the first flushing water channel. The water flow diverted 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.

[0014] Beneficial effects obtained by the above features: This embodiment increases the amount of water distributed to the siphon sewage pipe, thereby enhancing flushing in the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] See also Figures 1 to 4 The utility model provides a rotary flushing sewage toilet, including a pot body 3 with an open top, a seat ring 5 on the top of the pot body 3, 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 4 of the pot body extends to the upper 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, the siphon sewage pipe 10 is provided with a water supply channel 1, the rear end of the water supply channel 1 is connected to the drain hole of the water tank, and the back of the rear side wall 4 of the pot body is provided with a first flushing water channel 2, the upper end of the first flushing water channel 2 is connected to the upper water channel 1, and 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.

[0022] A second flushing water channel 11 is also provided inside the seat ring 5, one end of which is connected to the upper water channel 1, and the other end extends along the side of the seat ring 5 close to the first flushing water channel 2 toward the front end of the pot body 3. A circle outlet hole 12 is provided at the end, and the circle outlet hole 12 faces the front end of the pot body 3. This solution adopts a circle channel vortex structure to cooperate with the function of the first flushing water channel 2 of this solution. On the one hand, this structure has a better flushing performance on the pot surface. 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, thereby utilizing the potential energy of the circle channel water vortex to further energize the flushing water of the siphon drain pipe 10, achieving a one plus one greater than two effect.

[0023] This solution is designed to have water flow that enters the trap tangentially, forming an upward rotating water flow. The two ends of the trap are connected to the pot body and the siphon sewage pipe respectively, so that the rotating water flow is diverted to 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 the rotational potential energy, and the siphon effect formed by the pipe forms a rotating flow in the pipe; part of the water flow diverted to the pot body forms a rotating flushing at the bottom of the pot, thereby dazzling 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 into the sewage pipe.

[0024] 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 nearing the 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.

[0025] In this solution, the lower opening of the first flushing channel 2 is located behind the baffle 7 and is designed as a hidden structure. Except for the lower drain outlet, no other holes are visible on the pot body 3, thus reducing blind spots for cleaning and facilitating cleaning by users. On the one hand, this structure allows more water to be focused on flushing the drain outlet and directly remove 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 4 of the pot body is also the front wall of the first flushing water channel 2.

[0026] Existing toilets with secondary water channel spray holes usually produce relatively loud noises. This solution eliminates the spray holes in the pot, making it quieter.

[0027] This solution forms a rotating water flow that can roll back along the pipe wall by introducing water from the side of the pipe. 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.

[0028] Alternatively, the lower end of the first flush channel 2 can be tilted left or right, cutting into the side of the top wall of the inlet of the siphonic sewage pipe 10. Alternatively, the lower portion of the first flush channel 2 can bend left or right, cutting into the side wall of the water trap 9. This configuration of the first flush channel 2 creates a centrifugal force as the flushing water rushes downward from the first flush channel 2. The water directed through the first flush channel 2 rushes into the water trap 9, creating a strong vortex, exerting a strong impact on the pipe walls (including the walls of the water trap 9 and the walls of the siphonic sewage pipe 10).

[0029] As an option, the rear side wall 4 of the pot body converges toward the center, thereby causing the lower end of the first flushing water channel 2 to tilt toward the front end. As another option, the lower end of the rear side wall 4 of the pot body bends backward, thereby causing the lower end of the first flushing water channel 2 to tilt backward. The impulse inherited in the direction of the potential energy is large, the dirt at the bottom of the pot is heavy, and flushing of the sewage pipe is also the main purpose of this solution. Therefore, it is necessary to study the technical point of reasonable distribution of potential energy. The forward-leaning example makes the water flow rotation direction closer to the pot body 3, mainly focusing on flushing the pot bottom; the backward-bending example makes the water flow rotation direction closer to the siphon sewage pipe 10, mainly focusing on flushing the pipeline.

[0030] As an option, the lower end of the first flushing water channel 2 corresponds to the middle section of the trap 9 ; as another option, the lower end of the first flushing water channel 2 corresponds to the rear section of the trap 9 .

[0031] Due to the shape of the bottom surface of the 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 very necessary to reasonably distribute the water according to the model and shape of the toilet. The example of the opposite middle section makes the water flow distributed to the pot body 3 and the siphon drain pipe 10 balanced, and the example of the opposite rear section increases the water amount distributed to the siphon drain pipe 10, thereby strengthening the flushing in the pipeline.

[0032] 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 enables the miso to fall to the rear side of the lower opening of the pot body 3 after falling into the pot body 3, thereby being more easily carried away by the vortex.

[0033] The beneficial effects of the utility model are as follows: 1) In this solution, no other holes are seen in the pot body except the drainage hole at the cap head, thereby reducing cleaning dead corners; 2) the spray hole in the pot is eliminated, thereby reducing noise; 3) This solution forms a rotating water flow that can roll back along the pipe wall through the side water inlet of the pipe. 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.

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