Description

Technical Field

[0001] The present invention relates to the technical field of toilets, in particular to a double-rotation flushing anti-gravity toilet and a flushing method. Background Art

[0002] Toilets are a frequently used toilet tool in people's lives. Since toilets can provide people with sitting support during toileting and are convenient and clean for daily use, they are widely accepted and used by people.

[0003] In order to conveniently flush away the excrement adhering to the inner wall of the toilet bowl after use, the prior art toilets are usually provided with a flush outlet at the rear of the toilet bowl, and the flush outlet discharges water forward to flush and clean the inner wall of the toilet bowl. However, the point where the water is flushed out of the flush outlet of the existing toilet is often fixed and arranged at the upper part of the toilet bowl. The flushing method is usually to flush from top to bottom, and to increase the flushing cleaning effect by using the potential energy of gravity. However, such a flushing structure cannot completely cover the entire surface of the toilet bowl, and also makes it impossible to fully flush the inner surface of the toilet bowl during the flushing process.

[0004] At the same time, the existing toilet flushing port is relatively simple. When a large amount of water is flushed out from the flushing port in a short time, it will encounter greater resistance at the flushing port and produce greater noise. At the same time, the existing toilet flushing method is to flush from top to bottom. A large amount of water directly enters the sewage outlet, which will also cause the flushing and sewage discharge process to produce greater noise. In addition, when the user uses the toilet in a sitting position, the excrement is mainly concentrated in the lower back of the toilet bowl. In order to cover the inner surface of the toilet bowl as much as possible, the existing toilet flushing structure will set the water drop point of the flushing port on the upper inner wall of the toilet bowl. However, this will cause the flushing ability of the water to move downward and reduce the flushing and cleaning effect of the excrement. After long-term use, dirt will accumulate in the back of the toilet bowl, which will eventually increase the user's daily cleaning and maintenance workload. Summary of the Invention

[0005] The main purpose of the present invention is to propose a double-rotation flushing anti-gravity toilet and flushing method that flushes cleanly, discharges sewage sufficiently, and reduces noise quietly, aiming to optimize and improve the toilet bowl structure to achieve sufficient sewage discharge and efficient cleaning effects.

[0006] To achieve the above-mentioned objectives, the present invention proposes a dual-rotation flush anti-gravity toilet, comprising a toilet body and a water tank, the water tank being arranged at the rear of the toilet body, and a toilet bowl with a top opening being arranged in the front of the toilet body; the inner surface of the toilet bowl is provided with a first flushing layer, a second flushing layer and a third flushing layer in sequence from top to bottom, and there is a height difference between two adjacent flushing layers; a first flushing port is provided at the upper rear of the toilet bowl, the first flushing port flushes water outwardly into the surface of the first flushing layer and forms a first flushing trajectory, a second flushing port is provided at the lower rear of the toilet bowl and is located in the third flushing layer, the water flushed outwardly from the second flushing port enters the second flushing layer from the bottom to the top, moves along the surface of the second flushing layer and then enters the surface of the third flushing layer to form a second flushing trajectory, the end of the first flushing trajectory at least partially overlaps with the end of the second flushing trajectory, and the end of the second flushing trajectory is connected to the sewage outlet at the bottom of the toilet bowl.

[0007] Preferably, a flushing groove is provided in the third flushing layer, the second flushing port is located on the side of the central plane of the toilet bowl, one end of the flushing groove is connected to the second flushing port, and the other end of the flushing groove is connected to the sewage outlet. An upward inclined surface is provided on the side of the flushing groove and is connected to the second flushing layer, and the flushing direction of the second flushing port is parallel to the upward extension direction of the upward inclined surface.

[0008] Preferably, when flushing through the second flushing port, the amount of water flushed along the upward inclined surface is greater than the amount of water entering the flushing groove.

[0009] Preferably, when the second flush outlet flushes, part of the water entering the flush groove directly enters the sewage outlet along the flush groove to form the first siphon phenomenon; the water entering the second scouring layer along the upward inclined surface and then descending into the third scouring layer enters the flush groove again, and enters the sewage outlet along the flush groove to form the second siphon phenomenon.

[0010] Preferably, the ratio of the flushing volume of the first flushing port to the flushing volume of the second flushing port is 2-3:7-8, and a fixed pressure valve switch is provided at the front end of the second flushing port.

[0011] Preferably, when the toilet is in a non-flushing state, the second flushing layer and the third flushing layer are both filled with water, and the water depth in the second flushing layer is lower than the water depth in the third flushing layer.

[0012] Preferably, the central axis of the flushing groove is arc-shaped or semicircular.

[0013] Preferably, the first scouring layer and the second scouring layer have a smooth transition structure, and the second scouring layer and the third scouring layer have a smooth transition structure.

[0014] Preferably, the initial water outlet time of the first flushing port is 1-2 seconds earlier than the initial water outlet time of the second flushing port.

[0015] The present invention also provides a flushing method for the dual-flushing anti-gravity toilet, comprising the following steps:

[0016] Step S1: When the user finishes using the toilet and lightly presses the flush switch of the water tank, water is transported through the pipeline to the first flush port and the second flush port respectively. At this time, the water pressure is lower than the preset pressure value of the fixed pressure valve switch, and the water cannot be flushed out through the second flush port. The first flush port flushes water toward the surface of the first flushing layer to flush the excrement on the surface of the toilet bowl into the sewage outlet at the bottom;

[0017] Step S2: When the user finishes using the toilet, by pressing the flush switch of the water tank to the bottom, water is transported to the first flush port and the second flush port through the pipeline. At this time, the water pressure is greater than the preset pressure value of the fixed value valve switch, and the water can be flushed out from the first flush port and the second flush port at the same time;

[0018] Step S3: The water flowing out of the first flushing port flushes the surface of the first flushing layer and moves along the first flushing trajectory, flushing the excrement on the surface of the first flushing layer downwards;

[0019] Step S4: Part of the water flushed out from the second flush outlet moves along the flushing groove and introduces the excrement originally located in the third flushing layer into the sewage outlet at the bottom by a siphon phenomenon; another part of the water enters the second flushing layer along the upward inclined surface to converge and mix the excrement located in the second flushing layer and the excrement flushed down from the first flushing layer. The mixed water enters the flushing groove through the second flushing trajectory to form a siphon phenomenon again, and finally enters the sewage outlet at the bottom through the flushing groove.

[0020] The technical solution of the present invention has the following advantages over the prior art:

[0021] The technical solution of the present invention is to divide the inner wall of the toilet into a first flushing layer, a second flushing layer and a third flushing layer from top to bottom. The excrement of the user during the toileting process is mainly concentrated on the surface of the second flushing layer and the third flushing layer. Therefore, a first flushing port with a relatively small amount of water is set to flush the excrement on the surface of the first flushing layer with less excrement downward and collect it, and at the same time, a second flushing port with a larger amount of water is set to flush water from the third flushing layer to the second flushing layer, and the excrement located in the second flushing layer is flushed and collected to the sewage outlet. Through the above-mentioned flushing structure and the bottom-up flushing method, the excrement inside the toilet can be completely and fully flushed into the sewage outlet, so that the surface of the toilet is cleaned.

[0022] At the same time, the existing toilet flushing method is to flush from top to bottom, which produces a large flushing and sewage discharge noise. The technical solution of the present invention adopts a bottom-up method to flush specific areas in a targeted manner, and then the water and excrement automatically flow downward to discharge sewage, dividing the entire flushing and sewage discharge process into different stages, which can effectively reduce noise.

[0023] In addition, when the second flush outlet flushes out the water, part of the water enters the sewage outlet from the flushing groove to realize the first siphon phenomenon of sewage discharge. The water flushed from the second flush outlet from bottom to top and the water flowing downward from the first flush outlet merge together, and then enter the sewage outlet together to realize the second siphon phenomenon of sewage discharge. Therefore, compared with the flushing method of the existing technology, the two siphon methods can realize the full discharge of excrement and are not prone to blockage.

[0033] The present invention provides a double-flushing anti-gravity toilet.

[0034] See Figure 1 and Figure 2 In the embodiment of the present invention, the dual-flushing anti-gravity toilet includes a toilet body 1 and a water tank 2. The water tank 2 is arranged at the rear of the toilet body 1. A toilet bowl 3 with an open top is provided in the front of the toilet body 1. The inner surface of the toilet bowl 3 is provided with a first flushing layer 4, a second flushing layer 5 and a third flushing layer 6 from top to bottom. There is a height difference between the two adjacent flushing layers. Therefore, during the flushing process, water can flow from top to bottom. A first flushing port 31 is provided above the rear of the toilet bowl 3. The first flushing port 31 flushes water outward. The first flushing track 7 is formed by the surface of the first flushing layer 31 and the second flushing track 7 is formed. The second flushing port 32 is provided at the lower rear part of the toilet bowl and is located in the third flushing layer 6. The water flushed out of the second flushing port 32 enters the second flushing layer 5 from the third flushing layer 6 from bottom to top. The water moves along the surface of the second flushing layer 5 and then enters the surface of the third flushing layer 6 to form the second flushing track 8. The end of the first flushing track 7 at least partially overlaps with the end of the second flushing track 8, and the end of the second flushing track is connected to the sewage outlet 9 at the bottom of the toilet bowl 3.

[0035] To ensure reliable flushing, the third flushing layer 6 of this embodiment is provided with a flushing groove 61. The second flushing port 32 is located to the side of the center plane of the toilet bowl 3. One end of the flushing groove 61 is connected to the second flushing port 32, and the other end is connected to the sewage outlet 9. An upwardly inclined surface 62 is provided on the side of the flushing groove 61, connecting to the second flushing layer 5. The flushing direction of the second flushing port 32 is parallel to the upward extension of the upwardly inclined surface 62. Preferably, when flushing through the second flushing port 32 of this embodiment, the amount of water flushed along the upwardly inclined surface 62 is greater than the amount of water entering the flushing groove 61. Therefore, when water is flushed out through the second flushing port 32, most of the water moves from the third flushing layer 6 to the second flushing layer 5 via the upwardly inclined surface 62, while a small amount of water moves through the flushing groove 61. While the central axis of the flushing groove 61 of this embodiment is arc-shaped, in other embodiments of the present invention, the central axis of the flushing groove 61 may be semicircular or have other shapes.

[0036] At the same time, when flushing from the second flush port 32, part of the water entering the flush groove 61 flows directly along the flush groove 61 into the sewage outlet 9, forming a primary siphon phenomenon. The water that enters the second scouring layer 5 along the upwardly inclined surface 62 and then descends into the third scouring layer 6 re-enters the flush groove 61 and flows along the flush groove 61 into the sewage outlet 9, forming a secondary siphon phenomenon. Since excrement is primarily concentrated in the second and third scouring layers 5 and 6 when people use the toilet in a seated position, the primary siphon phenomenon caused by flushing from the second flush port 32 can draw all of the excrement in the third scouring layer 6 and part of the excrement in the second scouring layer 5 into the sewage outlet 9 for downward discharge. Furthermore, most of the water flushed from the second flush port 32 can flow along the upwardly inclined surface 62 into the second scouring surface 5, then merge with the water flushed from the first flush port 31 and enter the third scouring layer 6 together, ultimately entering the sewage outlet 9 for downward discharge.

[0037] Preferably, the ratio of the flushing volume of the first flush port 31 to the flushing volume of the second flush port 32 in this embodiment is 2-3:7-8, so that the second flush port 32 has a larger flushing volume, which can effectively clean the excrement on the surface of the second flushing layer 5 and the third flushing layer 6. In addition, a fixed pressure valve switch is provided at the front end of the second flushing port 32 of this embodiment. Therefore, when the user lightly presses the flush switch of the water tank, the small amount of water is insufficient to overcome the closing pressure value of the fixed pressure valve switch. Therefore, the water can only flush outward through the first flushing port 31, that is, directly flush the surface of the first flushing layer 4, and then the water moves from the first flushing layer 4, the second flushing layer 5, and the third flushing layer 6 by its own weight, and finally flushes the excrement into the sewage outlet 9. When the user presses the flush switch to the bottom, the water inside the water tank flows through the pipe toward the first flush port 31 and the second flush port 32. Since the water pressure at this time is greater than the closing pressure value of the pressure valve switch, the water can be discharged through the second flush port 32, and some water is also discharged outward through the first flush port 31.

[0038] Preferably, when the toilet of this embodiment is in a non-flushing state, the second flushing layer 5 and the third flushing layer 6 are both filled with water, and the water depth inside the second flushing layer 5 is lower than the water depth inside the third flushing layer 6. Preferably, the first flushing layer 4 and the second flushing layer 5 of the toilet of this embodiment are transitioned with a smooth structure, and the second flushing layer 5 and the third flushing layer 6 are transitioned with a smooth structure. Through the above structure, the second flushing layer 5 can form a shallow water area, and the third flushing layer 6 can form a deep water area. Therefore, when the user uses the toilet, the excrement falls on the second flushing layer 5 and is not likely to splash large water upwards. The excrement falling into the second flushing layer 5 can slide down the inclined surface into the third flushing layer 6, so that the excrement is not likely to emit odor to the outside.

[0039] See Figure 1 and Figure 2 The present invention also proposes a flushing method for a dual-flush anti-gravity toilet. When the user finishes using the toilet, by lightly pressing the flush switch of the water tank, water is transported to the first flush port 31 and the second flush port 32 through the pipeline. At this time, the water pressure is lower than the preset pressure value of the fixed pressure valve switch, and the water cannot be flushed out through the second flush port 32. The first flush port 31 flushes water to the surface of the first flushing layer 4 to flush the excrement on the surface of the toilet bowl 3 into the sewage outlet 9 at the bottom.

[0040] When the user finishes using the toilet, they press the flush switch of the water tank 2 to the bottom. Water is then pumped through the pipe to the first flush port 31 and the second flush port 32. At this point, the water pressure is greater than the preset pressure value of the fixed-value valve switch, and water is simultaneously flushed out of the first flush port 31 and the second flush port 32. The water flushing out of the first flush port 31 flushes the surface of the first flushing layer 4 and moves along the first flushing track 7, flushing the excrement on the surface of the first flushing layer 4 downward. Part of the water flushed out from the second flush outlet 32 ​​moves along the flushing groove 61 and introduces the excrement originally located in the third scouring layer 6 into the sewage outlet 9 at the bottom by a siphon phenomenon; another part of the water enters the second scouring layer 5 along the upward inclined surface to converge and mix the excrement located in the second scouring layer 5 and the excrement flushed down from the first scouring layer 4. The mixed water enters the flushing groove 61 through the second flushing track 8 to form a siphon phenomenon again, and finally enters the sewage outlet at the bottom through the flushing groove 61.

[0041] In other embodiments of the present invention, the initial water discharge time of the first flushing port 31 is 1-2 seconds earlier than the initial water discharge time of the second flushing port 32 .

[0042] It should be noted that the water tank 2 of this embodiment can be a push-to-storage water tank of an ordinary toilet or can be a smart toilet water tank directly connected to a water pipe, which is not limited here.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
