Description

Technical Field

[0001] This invention belongs to the field of sanitary ware technology, specifically relating to a double-vortex toilet. Background Technology

[0002] Toilets are common bathroom fixtures in homes. In the field of toilet production and design, toilets utilize the pushing force of water flow on waste and / or the suction force of siphon to remove waste. How to improve the waste removal capacity of toilets is one of the mainstream topics in toilet design improvement.

[0003] Traditional toilets typically have a main water channel connecting to the tank, which in turn connects to the rim. The rim has evenly spaced perforations around the rim. Flushing water flows through these perforations into the rim, causing the water level to rise and siphoning out waste. While the traditional perforation structure allows for a more thorough flushing of the rim, the water flow per perforation is small, resulting in less scrubbing force on the rim's surface.

[0004] To increase the flushing force of water flow on the surface of the pot, the prior art also provides a swirling flushing structure with a side channel and a single spray hole. Specifically, a side channel connected to the main channel is set under the seat ring, and a spray hole is set in the spray part of the side channel. The water in the side channel is discharged in a concentrated manner through the spray hole. The water flow has a large momentum and a fast water flow speed, thereby increasing the flushing force of the water flow on the surface of the pot.

[0005] Household waste discharged through toilets is often not simply liquid or solid; it can be mucus, floating matter, residue, or even a mixture that clumps together but disperses in water, forming a complex physical structure. Current toilet technology commonly uses a single flush, frequently resulting in waste residue. Specifically: 1) Toilets with a perforated design allow flushing water to flow into the bowl in one go, which is effective in removing liquids and light floating matter, but less effective in removing solid waste. 2) With a single jet hole structure, the rinsing water flows into the pot body at one time and forms a swirling jet inside the pot. The water flow speed is fast and the effect of discharging solid dirt is good. However, the water flow spirals down on the pot wall, and there is a situation where the pot wall is not completely rinsed, and light floating objects are easily left behind.

[0006] 3) Existing technologies also include structures with water guide channels or multiple spray holes along the side channels to improve the coverage of the rinsing water on the surface of the pot. However, after the mixed clump of dirt is broken down by water impact, a water stain or floating object will remain on the upper layer of the water due to buoyancy, or be splashed onto the upper side of the pot by splashing water. After the rinsing water flows into the pot, it can only flow downwards and cannot backwash the water stain and floating object that have already adhered to the upper surface of the pot. Therefore, there is also the problem of incomplete rinsing. Summary of the Invention

[0007] The technical problem to be solved by this invention is to improve the waste disposal effect of the toilet, especially to solve the problem of waste splashing onto the upper side of the pot wall during the flushing process.

[0008] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A double-vortex toilet includes a pot body, a side water channel is provided on one side of the inner wall of the pot body, a jet hole is provided at the end of the side water channel, and a water guide ring is provided on the outside of the jet hole. The water guide ring includes two ring grooves, an upper ring groove and a lower ring groove, which are arranged parallel to each other.

[0009] Compared with the prior art, the present invention employing the above structure has the following advantages: This invention uses upper and lower water guide rings to allow water to flow into the bottom of the pot in staggered order. The water flow in the lower ring groove is used to impact and discharge the dirt at the bottom of the pot, while the water flowing down the upper ring groove afterward washes away the dirt that splashed onto the upper side when the lower ring groove was flushed, thus thoroughly removing the dirt.

[0010] As a preferred option, a further technical solution to the above structure is: The upper annular groove guides the water flow to the entire circumference of the pot body, while the lower annular groove disperses and releases the water flow to the bottom of the pot body. Specifically, the upper annular groove extends horizontally around the entire length of the inner wall of the pot body, and the lower annular groove extends along a quarter of the length of the inner wall of the pot body.

[0011] The beneficial effects obtained from the above features are as follows: This scheme allows the water in the lower annular groove to flow into the pot body significantly earlier than the water in the upper annular groove. The water in the lower annular groove is concentrated on moving dirt, while the water in the upper annular groove is used to thoroughly rinse the surface of the pot body, thus achieving the purpose of rationally allocating rinsing force and water volume according to the rinsing target.

[0012] The upper annular groove extends horizontally along the inner wall of the pot for one circumference, and the lower annular groove extends along the inner wall of the pot for one-quarter of the pot's circumference.

[0013] The beneficial effect obtained from the above features is that this structure allows water from the upper and lower annular grooves to flow into the pot body sequentially.

[0014] The upper annular groove is wider at the turning points, narrower in the straight sections, and gradually disappears at the end; the lower annular groove is wider at the beginning and gradually disappears.

[0015] The beneficial effects obtained from the above features are as follows: The water guide channel structure provided in this embodiment can reasonably and quickly release the water in the lower ring channel and disperse it so that it can have more contact with the inner wall of the pot. It can also reasonably delay the downward flow of the upper ring channel and evenly guide the water to the upper side of the pot as a whole, especially avoiding the situation that the water volume on the rear side is too small.

[0016] The top surface of the upper annular groove is an arc-shaped groove; the arc-shaped groove can retain more water and prevent the water from flowing out prematurely.

[0017] An upper jet hole is provided on the upper side of the end of the side channel, and a lower jet hole is provided on the lower side. The upper jet hole corresponds to the upper annular groove, and the lower jet hole corresponds to the lower annular groove.

[0018] The beneficial effects obtained from the above features are: the scheme achieves water distribution to the upper and lower annular grooves through two injection holes, which facilitates and accurately controls the water distribution ratio.

[0019] Based on the direction of the flushing water flow, the upper jet hole is located in front of the lower jet hole, and its water output is delayed relative to the lower jet hole.

[0020] The beneficial effects obtained from the above features are as follows: the staggered upper and lower spray holes result in greater potential energy of the water flow in the lower annular groove, which can effectively push the solid waste at the bottom of the pot out, reduce the force of the water flow in the upper annular groove, and thus allow the water to flow backward along the annular groove, further staggering the time of the water flow in the lower annular groove.

[0023] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0024] See Figures 1 to 7The present invention provides a double vortex toilet, including a pot body 1. A side water channel 4 is provided on one side of the inner wall of the pot body 1. A jet hole is provided at the end of the side water channel 4. A water guide ring is provided on the outside of the jet hole. The water guide ring includes two ring grooves, an upper ring groove 2 and a lower ring groove 3. The upper ring groove 2 and the lower water guide groove are arranged in parallel.

[0025] The upper annular groove 2 is used to guide the water flow to the entire circumference of the pot body 1, and the lower annular groove 3 is used to disperse the water flow to the bottom of the pot body 1.

[0026] This invention utilizes two water-guiding rings, one above the other, to allow water to flow into the pot bottom in a staggered sequence. The lower ring trough 3, closer to the pot bottom, allows water to enter the pot body 1 first. Its shape guides the dispersed water flow into the pot body 1, impacting and discharging the dirt at the bottom. The upper ring trough 2, further from the bottom than the lower ring trough 3, intercepts and guides the water flow backward, delaying its impact on the pot body 1. This design achieves the following effects: the lower ring trough 3 carries a larger volume of water, flowing into the pot body 1 first to impact and push away solid dirt at the bottom; the upper ring trough 2 carries a smaller volume of water, flowing into the pot body 1 later. It then rinses away any splashed wastewater or lightweight floating particles separated from the solid dirt that adhere to the pot wall during the impact of the solid dirt in the lower ring trough 3, thus thoroughly removing the dirt.

[0027] Optionally, the upper annular groove 2 extends horizontally along the inner wall of the pot body 1 for one circumference, and the lower annular groove 3 extends along the inner wall of the pot body 1 for one-quarter of the pot body's total circumference. Utilizing the structure of the upper annular groove 2 and the lower annular groove 3, the water flow from the lower annular groove 3 into the pot body 1 occurs significantly earlier than the water flow from the upper annular groove 2. The water flow from the lower annular groove 3 is concentrated on dispersing dirt, while the water from the upper annular groove 2 is used to thoroughly rinse away lightly adhering substances from the surface of the pot body 1.

[0028] As an alternative, the upper annular groove 2 has a wider turning section, a narrower straight section, and a reduced or even disappearing structure at the end; the lower annular groove 3 has a wide beginning and a gradually disappearing structure.

[0029] The top surface of the upper annular groove 2 is an arc-shaped groove (not shown). The arc-shaped groove can retain more water and prevent water from flowing out prematurely.

[0030] Both the widened and grooved water-guiding surfaces can retain more water, preventing excessive water loss during turns. The lower annular groove 3 is designed to be short and gradually disappear to disperse the water, causing the water flow to spiral downwards and making it contact the inner wall of the pot body 1 more frequently. In this embodiment, the shape of the upper annular groove 2 slows down the downward flow of water and evenly guides it to the upper side of the pot body 1. The varying groove width prevents the water volume at the rear from being too small.

[0031] Alternatively, an upper jet hole 201 is provided on the upper side of the end of the side channel 4, and a lower jet hole 301 is provided on the lower side. The upper jet hole 201 corresponds to the upper annular groove 2, and the lower jet hole 301 corresponds to the lower annular groove 3. Water is divided through the two jet holes, which facilitates accurate control of the water division ratio.

[0032] Furthermore, based on the direction of the rinsing water flow, the upper spray hole 201 is positioned in front of the lower spray hole 301, causing it to delay water flow relative to the lower spray hole 301. The staggered arrangement of the upper spray hole 201 and the lower spray hole 301 results in greater potential energy for the water flow in the lower annular groove 3, effectively pushing solid waste from the bottom of the pot out and reducing the force of the water flow in the upper annular groove 2, allowing it to flow backward along the annular groove and further staggering the flow time with the water flow in the lower annular groove 3.

[0033] In this design, the cross-sectional ratio of the upper spray hole 201 to the lower spray hole 301 is 2:8 or 3:7. This cross-sectional ratio represents the water distribution ratio. This design is such that the water volume in the lower annular groove 3 is greater than that in the upper annular groove 2. The water flow in the lower annular groove 3 is for solid dirt, while the water flow in the upper annular groove 2 is for light adhering substances (water droplets, paper scraps, small particles, etc.) on the surface of the pot body 1. Therefore, a large water volume and flow rate are not required.

[0034] As an embodiment of the injection hole setting position of the present invention: the upper injection hole 201 and the lower injection hole 301 are set at the middle position on the side of the pot body 1 near the main water channel.

[0035] As an embodiment of the annular groove shape of the present invention: the upper annular groove 2 has a width of 0-15mm at the front of the pot body 1, a width of 5mm-15mm at the side of the pot body 1, a width of 15mm-20mm at the rear corner of the pot body 1, and a width of 0-10mm extending to the back side of the spray hole.

[0036] The beneficial effects of this invention are: 1) Through the upper and lower water guide rings, the rinsing water is rinsed on the surface of the pot body in sequence, and a secondary rinsing can be achieved for the splashing of dirt caused by strong rinsing water. 2) The length of the annular groove further staggers the action time of the two water flows, creating a clear distinction between the front and rear water jets; 3) By diverting water through the spray holes, the water distribution ratio can be accurately controlled to achieve the purpose of rationally allocating flushing force and water volume to the flushing target.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
