Description

Technical Field

[0001] This utility model relates to the technical field of toilet base structure, specifically a concealed vortex flush toilet base structure. Background Technology

[0002] In the field of bathroom fixtures, toilets, as core cleaning appliances, directly affect user experience and hygiene safety through their flushing performance. Currently, traditional toilets generally use exposed nozzles, with the water flow direction typically vertically downwards or nearly vertical.

[0003] Because the water jet from the nozzle is directed vertically downwards, the kinetic energy of the water spreads rapidly radially upon contact with the pot surface, failing to form a concentrated impact vector and resulting in a significant reduction in water impact pressure. Furthermore, the exposed nozzle design makes the water flow susceptible to air resistance during transport, and turbulence easily occurs at the junction of the nozzle and the water channel, causing some energy loss and further weakening the water's impact capability. For stubborn stains such as hardened feces and adhesive dirt, the traditional vertically downward water flow struggles to overcome the adhesion tension between the dirt and the glaze, resulting in noticeable dirt residue after rinsing. Users need to rinse multiple times to achieve a basic cleaning effect, reducing ease of use and wasting water resources. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model proposes a concealed vortex flush toilet base structure. By setting up a water outlet guide and a vortex flush branch channel, this application not only hides the water outlet at the bottom of the wash ring, but also increases the impact force of the water flow, solving the problem of weak flushing power and inadequate cleaning of pot surfaces in traditional toilets.

[0005] To achieve this objective, the present invention adopts the following technical solution: A concealed vortex flush toilet base structure includes a wash ring and a bowl connected to each other. The wash ring has a hollow interior forming a vortex flush main water channel. The end of the wash ring is provided with a water inlet. The bottom of the wash ring is provided with at least two vortex flush ports. The vortex flush main water channel is connected to the water inlet. The bottom wall of the washing ring protrudes upward at the vortex inlet to form a water outlet guide, and the area below the water outlet guide forms a vortex branch channel; the vortex branch channel is connected to the vortex main channel, the water flow direction of the vortex branch channel is inclined downward, and the water outlet of the vortex branch channel forms a vortex inlet.

[0006] The water outlet guide section is provided with a guide slope and a conical slope in sequence along the water flow direction. The conical slope is inclined to connect the outer periphery of the guide slope and the bottom wall of the washing ring. A water guide is provided at the end of the vortex flushing branch waterway that is close to the vortex flushing main waterway. The water guide is located on the guide slope. The end of the vortex flushing branch waterway that is away from the vortex flushing main waterway forms a vortex flushing outlet. The water guide is used to allow water flow from the main vortex channel to flow into the vortex branch channel, the conical inclined surface is used to collect the water flow sprayed from the water guide, and the vortex outlet is used to spray water outward.

[0007] The washing ring is provided with the water inlet at the bottom of the vortex main water channel. The side of the washing ring near the water inlet is provided with an arc surface. The arc surface is inclined to connect the water inlet and the vortex main water channel. The water inlet is connected to the vortex main water channel. The arc surface is inclined from bottom to top in the direction away from the water inlet.

[0008] The direction of water flow in the vortex branch channel forms an angle of inclination α with the direction of water flow in the vortex main channel, and the angle of inclination α is 12-17°.

[0009] The top of the pot surface is recessed inward to form a water-retaining groove. The bottom of the water-retaining groove is smoothly connected to the water-rinsing surface of the pot surface. The top wall of the water-retaining groove is fixedly connected to the bottom wall of the washing ring.

[0010] A chamfer is provided between the guide slope and the bottom wall of the washing ring, and a chamfer is provided between the conical slope and the bottom wall of the washing ring.

[0011] The vortex flushing port includes a first sub-vortex flushing port, a second sub-vortex flushing port, and a third sub-vortex flushing port. The first sub-vortex flushing port is located on the annular wall section of the washing ring adjacent to the water inlet. The second sub-vortex flushing port is located on the annular wall section on the front side of the washing ring. The third sub-vortex flushing port is symmetrically arranged with respect to the first sub-vortex flushing port.

[0012] The technical solution of this utility model can include the following beneficial effects: 1. The water outlet of the vortex flushing branch channel forms a vortex flushing port, which allows the water outlet of the toilet in this application to be hidden at the bottom of the wash ring through the water outlet guide, avoiding the problem of sanitary dead corners such as grooves and gaps formed by the exposed water outlet of traditional toilets.

[0013] 2. When the water flows from the main vortex channel into the inclined branch channel, it accelerates along the inclined trajectory under the influence of gravity. Simultaneously, the inclination angle gives the water a clear radial directionality, transforming potential energy into a composite kinetic energy of downward gravitational acceleration and radial directional impact. This potential energy conversion mode allows the water flow to gain stronger initial momentum, quickly overcoming the adhesion tension between stubborn dirt and the glaze surface, completely solving the problem of insufficient impact caused by potential energy dissipation in traditional designs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following is combined with Figures 1 to 4 This invention describes a concealed vortex flush toilet base structure according to an embodiment of the present invention.

[0020] A concealed vortex flush toilet base structure includes a wash ring 1 and a bowl 2 connected to each other. The wash ring 1 has a hollow interior forming a vortex flush main water channel 101. The end of the wash ring 1 is provided with a water inlet 105. The bottom of the wash ring 1 is surrounded by at least two vortex flush ports 104. The vortex flush main water channel 101 is connected to the water inlet 105. The bottom wall of the washing ring 1 protrudes upward at the vortex inlet 104 to form a water outlet guide 11, and a vortex branch channel 102 is formed in the area below the water outlet guide 11; the vortex branch channel 102 is connected to the vortex main channel 101, the water flow direction of the vortex branch channel 102 is inclined downward, and the water outlet of the vortex branch channel 102 forms the vortex inlet 104.

[0021] Since the inlet 105, the main vortex channel 101, and the branch vortex channel 102 are connected, the water introduced by the inlet 105 passes through the main vortex channel 101, and then is divided in the branch vortex channel 102. Finally, the water is sprayed outward from the vortex outlet 104, thus forming a surrounding vortex water flow, achieving full coverage of the pot surface 2 without dead angles.

[0022] The bottom wall of the washing ring 1 has an inwardly protruding water outlet guide 11, and the area below the water outlet guide 11 forms a vortex flushing channel 102. Therefore, the water outlet guide 11 can accurately guide the water flow and concentrate energy, prevent the water flow from spreading, keep the water flow in the vortex flushing channel 102 with concentrated kinetic energy, and enhance the flushing impact force.

[0023] The water outlet of the vortex flushing channel 102 forms a vortex flushing port 104, which allows the water outlet of the toilet in this application to be hidden at the bottom of the wash ring 1 through the water outlet guide part 11, thus avoiding the problem of sanitary dead corners such as grooves and gaps formed by the exposed water outlet of traditional toilets.

[0024] The vortex branch channel 102 is inclined, and by optimizing the angle between the water flow direction and the direction of gravity, the gravitational potential energy of the water flow is efficiently converted into directional impact kinetic energy. When the water flows from the vortex main channel 101 into the inclined branch channel, it accelerates along the inclined trajectory under the action of gravity. At the same time, the inclination angle gives the water flow a clear radial directionality, so that the potential energy conversion forms a composite kinetic energy of downward gravitational acceleration and radial directional impact. This potential energy conversion mode gives the water flow stronger initial momentum, which can quickly overcome the adhesion tension of stubborn dirt and glaze, and completely solve the problem of insufficient impact caused by potential energy dissipation in traditional designs.

[0025] Therefore, by setting up the water outlet guide section 11 and the vortex flushing branch water channel 102, this application not only hides the water outlet at the bottom of the wash ring 1, but also increases the impact force of the water flow, solving the problem that the traditional toilet has weak flushing power and the pot surface 2 is not cleaned properly.

[0026] The water outlet guide section 11 is provided with a guide slope 111 and a conical slope 112 in sequence along the water flow direction. The conical slope 112 is inclined to connect the outer periphery of the guide slope 111 and the bottom wall of the washing ring 1. A water guide 103 is provided at one end of the vortex branch waterway 102 near the vortex main waterway 101. The water guide 103 is located on the guide slope 111. A vortex outlet 104 is formed at one end of the vortex branch waterway 102 away from the vortex main waterway 101. The water inlet 103 is used to allow the water flow from the main vortex channel 101 to flow into the vortex branch channel 102. The conical inclined surface 112 is used to collect the water flow sprayed from the water inlet 103. The vortex outlet 104 is used to spray water outward.

[0027] Since the water inlet 103 is located on the guide slope 111, the guide slope 111 first guides the water flow of the vortex main channel 101 in a predetermined direction, ensuring that the water flow smoothly enters the vortex branch channel 102 along the preset trajectory, and avoiding the loss of vector kinetic energy caused by the deflection of the water flow.

[0028] The conical inclined surface 112 is inclined to connect the outer periphery of the guide inclined surface 111 and the bottom wall of the washing ring 1, which can quickly gather the dispersed water flow sprayed from the water guide 103 into a concentrated stream, reducing the energy waste caused by water flow diffusion.

[0029] The conical inclined surface 112 and the tilt angle work together to create a synergistic effect, allowing the water flow to maintain the impact vector brought about by the tilt direction and form a high-intensity directional impact jet.

[0030] Since the water inlet 103 is located on the guide slope 111, the guide slope 111 first guides the water flow of the vortex main channel 101 in a predetermined direction, ensuring that the water flow smoothly enters the vortex branch channel 102 along the preset trajectory, and avoiding the loss of vector kinetic energy caused by the deflection of the water flow.

[0031] The conical inclined surface 112 is inclined to connect the outer periphery of the guide inclined surface 111 and the bottom wall of the washing ring 1, which can quickly gather the dispersed water flow sprayed from the water guide 103 into a concentrated stream, reducing the energy waste caused by water flow diffusion.

[0032] The conical inclined surface 112 and the tilt angle work together to create a synergistic effect, allowing the water flow to maintain the impact vector brought about by the tilt direction and form a high-intensity directional impact jet.

[0033] After the water enters from the bottom inlet 105, it gains initial circumferential kinetic energy upward and along the tangential direction of the vortex main channel 101 under the guidance of the arc surface 12, avoiding the impact turbulence generated when the water enters the main channel vertically, and significantly reducing the energy loss during the water intake stage.

[0034] Next, the high-velocity water flow is quickly diverted through the main vortex channel 101 to each vortex branch channel 102. This allows for more full utilization of the impact vector imparted by the tilt angle of the vortex branch channel 102, forming a dual enhancement effect of initial kinetic energy and tilt impact kinetic energy. This gives the concentrated jet from the vortex nozzle 104 stronger penetrating power and improves the cleaning power of the pot surface 2.

[0035] The water flow direction of the vortex branch channel 102 forms an inclination angle α with the water flow direction of the vortex main channel 101, and the inclination angle α is 12-17°.

[0036] Through fluid dynamics simulation and actual testing optimization, this application limits the tilt angle α to 12-17°. This angle range precisely balances the radial impact kinetic energy and tangential circumferential kinetic energy of the water flow. When the angle is less than 12°, the radial impact component of the water flow is insufficient, making it difficult to generate a strong impact force to remove dirt. When the angle is greater than 17°, the water flow is prone to detaching from the pot surface 2, causing splashing, and the increased frictional resistance leads to aggravated energy loss. The golden angle α of 12-17° allows the water flow to maintain a stable circumferential flow state while converting the kinetic energy of the water flow into radial impact energy pointing towards the center of the pot surface 2, thereby improving the cleaning power of the pot surface 2 and achieving rapid removal of stubborn stains.

[0037] The top of the pot surface 2 is recessed inward to form a water storage groove 21. The bottom of the water storage groove 21 is smoothly connected to the water rinsing surface of the pot surface 2. The top wall of the water storage groove 21 is fixedly connected to the bottom wall of the washing ring 1.

[0038] The inward-curving water-retaining groove 21 at the top of the pot surface 2 provides a stable base for the strong impact vortex water flow brought by the vortex outlet 104. The water stored in the water-retaining groove 21 can form a preset water layer. When the strong impact water flow washes along the pot surface 2, the preset water layer and the vortex water flow work together to enhance the continuity of the water flow vortex and amplify the impact kinetic energy through the buffer-reflection effect of the water layer, thereby increasing the impact force of the water flow on the periphery of the water-retaining groove 21 and the water surface of the pot surface 2.

[0039] Meanwhile, the bottom of the water storage groove 21 is smoothly connected to the flushing surface without any protrusions or sharp edges, avoiding obstruction of the flow trajectory of the strong impact water flow, ensuring that the water flow transmits impact energy in a lossless state, thoroughly removing dirt that is easily left in the water storage area, and solving the problem of cleaning blind spots around the water storage line of traditional toilets.

[0040] A chamfer is provided between the guide inclined surface 111 and the bottom wall of the washing ring 1, and a chamfer is provided between the conical inclined surface 112 and the bottom wall of the washing ring 1.

[0041] The guide ramp 111 and the bottom wall of the washing ring 1, and the conical ramp 112 and the bottom wall of the washing ring 1, are respectively chamfered to form a smooth transition flow channel structure, completely eliminating the flow channel sharp edges caused by traditional right-angle connections. The chamfer design, through fluid dynamics optimization, can effectively suppress the formation of eddies and turbulence in the water flow at the junction of the guide ramp 111 and the bottom wall, and at the junction of the conical ramp 112 and the bottom wall, reducing the friction loss of the water flow and making the water flow smoother along the convergence path of the guide ramp 111 and the conical ramp 112.

[0042] The vortex flushing port 104 includes a first sub-vortex flushing port, a second sub-vortex flushing port, and a third sub-vortex flushing port. The first sub-vortex flushing port is located on the annular wall section of the washing ring 1 adjacent to the water inlet 105. The second sub-vortex flushing port is located on the front annular wall section of the washing ring 1. The third sub-vortex flushing port is symmetrically arranged with respect to the first sub-vortex flushing port.

[0043] The first sub-vortex flushing port is located next to the annular wall section of the inlet 105, which allows the first sub-vortex flushing port to directly obtain the high initial kinetic energy water flow after being guided by the arc surface 12, forming a strong flushing zone near the water source, thereby quickly breaking through the stubborn dirt around the side of the inlet 105.

[0044] The third sub-vortex flushing outlet is symmetrically distributed with the first sub-vortex flushing outlet. It receives the water flow smoothly transmitted through the main vortex flushing channel 101 and forms a symmetrical impact balance with the first sub-vortex flushing outlet, avoiding the situation where the kinetic energy on one side is attenuated, resulting in the water flow deviating and the flushing not being complete.

[0045] The second sub-vortex flush nozzle is specifically positioned on the annular wall section in front of the wash ring 1, precisely covering the blind spot in front of traditional toilets where dirt tends to remain. The concentrated jets from the first, second, and third sub-vortex flush nozzles form a triple-impact network on the wash surface 2, combining strong flushing from both sides with supplementary flushing from the front. This allows for precise, zoned cleaning of different areas of dirt, thus addressing the problem of weak localized cleaning in traditional toilets.

[0046] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
