Abstract
Description
Technical Field
[0001] This utility model relates to a vortex-wash flush toilet. Background Technology
[0002] A direct-fall water-saving and silent toilet disclosed in Chinese utility model patent (CN219794110U) features a first and second annular flow guide sections arranged in a triangular pattern, connected from top to bottom, on the ring wall of the flow guide channel connecting the toilet bowl and the sewage pipe. When the toilet is flushed, the water flows downwards and rotates within the toilet bowl. Under the influence of gravity and the downward tilt of the toilet bowl, the rotating water gathers at the bottom of the bowl and enters the flow guide channel. Passing through the first and second annular flow guide sections, a first and second vortex are formed within the flow guide channel, maximally delaying and slowing the drainage time to the sewage pipe. With continuous water supply to the flow guide channel from the toilet bowl, the problem of low water pressure and slow flow rate in the flushing channel is solved, allowing the flow guide channel to quickly fill with water, creating a pressure difference against the sewage pipe and achieving the desired flushing effect. In addition, to solve the problem of water splashing, the patent provides a diversion surface with a high beginning and low end between the vertical surface and the lower slope of the toilet bowl edge.
[0003] However, the above-mentioned patent has the following problems: (1) Since the water flow in the toilet bowl rotates and gathers along the surface of the bowl and enters the guide channel, the time for the water to enter the guide channel is not fast enough and the water volume is not large enough. Therefore, in order to avoid the sewage pipe from draining the guide channel too fast and too much before the guide channel is filled with water, the inner diameter of the sewage pipe can only be reduced. The reduction of the inner diameter of the sewage pipe will lead to a weakening of the flushing and sewage discharge capacity, which is not conducive to flushing and sewage discharge; (2) When the toilet bowl is swirled with high water pressure and high flow rate, the swirling water on the edge of the toilet bowl will still climb up along the inner vertical surface of the toilet bowl under the guidance of the diversion surface and be thrown out and splashed outside the bowl or flow out from the overflow port. Utility Model Content
[0004] This invention provides a vortex brush flush toilet that can effectively solve the above problems.
[0005] This utility model is implemented as follows:
[0006] A vortex-flush toilet includes a toilet bowl, a sludge collection well at the bottom of the toilet bowl, and a drain pipe connected to the sludge collection well. A water inlet is provided on the right side of the toilet bowl's rim, and a water flow surface is provided inside the toilet bowl.
[0007] The water flow surface on the left side of the toilet bowl is equipped with a wedge-shaped flow surface, a swirling sill, and a deceleration sill from front to back around the sludge collection well opening. The wedge-shaped flow surface is located at the well opening where the swirling sill leads into the sludge collection well. The large stream of water supplied to the toilet bowl is swirled back into the sludge collection well by the swirling sill, and merges with a portion of the water flow that is blocked by the deceleration sill and flows into the sludge collection well from behind the water flow surface to form a flushing water column. Another portion of the water flow is wedged into the sludge collection well by the wedge-shaped flow surface to form a vortex flushing water column. The flushing water column is tangentially rolled by the vortex flushing water column and, under the action of gravity, forces the sewage in the sludge collection well out through the drain pipe for discharge.
[0008] As a further improvement, the height of the bedpan gradually decreases from the right rear clockwise to the left front, and gradually increases from the left front clockwise to the right rear.
[0009] As a further improvement, if the horizontal inclination angle of the water surface on the right side of the toilet bowl is A, and the horizontal inclination angle of the water surface on the left side of the toilet bowl is B, then A > B.
[0010] As a further improvement, the horizontal inclination angle A of the water surface on the right side of the toilet bowl is 15-20°, and the horizontal inclination angle B of the water surface on the left side of the toilet bowl is 5-10°.
[0011] As a further improvement, a pressure-guiding slope is provided at the bottom of the sewage collection well. The pressure-guiding slope includes a convex arc annular surface and a concave arc annular surface that transition smoothly from top to bottom.
[0012] As a further improvement, an overflow outlet is provided on the upper part of the vertical surface of the back basin of the water-flowing surface.
[0013] As a further improvement, a recessed space is also included, behind which is a rear wall panel, and a socket pipe connected to the end of the socket drain pipe is installed in the recessed space.
[0014] As a further improvement, an L-shaped reinforcing plate is provided above the socket tube. One end of the reinforcing plate is integrally formed and connected to the outer wall of the upper part of the socket tube, and the other end of the reinforcing plate is integrally formed and connected to the inner side wall of the rear wall plate.
[0015] The beneficial effects of this utility model are:
[0016] (1) The toilet bowl is equipped with "two sills and one surface" on the water surface; the swirling sill is used to swirl the large flow of water supplied to the toilet bowl into the sludge collection well; the deceleration sill is used to slow down the flow rate of the water on the brush ring surface that crosses the swirling sill, so as to prevent the water on the brush ring surface from splashing out of the overflow outlet under the centrifugal force; the wedge surface is set at the wellhead of the sludge collection well where the swirling sill leads to the wellhead, and wedges a part of the water flow into the wellhead from the edge of the wellhead, so that the large flow of water entering the wellhead is tangentially swirled and rotated, which not only serves the purpose of rotating and scrubbing the inner wall of the wellhead, but also delays the speed at which the water flow from the wellhead enters the sewage pipe, so as to quickly raise the water level in the wellhead, and realize that the water column in the wellhead falls under the action of gravity to push the sewage out of the sewage pipe and discharge the sewage.
[0017] (2) A pressure-guiding slope is provided at the bottom of the sewage collection well, which can narrow the bottom opening of the sewage collection well, so that the water flow at the bottom opening of the sewage collection well is pressurized and smoothly guided to the sewage pipe, which makes the sewage discharge smoother and reduces the sewage discharge noise.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0034] Reference Figures 1-3 As shown, a vortex-flush flush toilet includes a toilet bowl 10, a sludge collection well 20 located at the bottom of the toilet bowl 10, and a drain pipe 30 connected to the sludge collection well 20. A water inlet 13 is located on the right side rim 11 of the toilet bowl 10. A water flow surface 12 is located inside the toilet bowl 10. The water flow surface 12 on the left side of the toilet bowl 10, from front to back and surrounding the opening of the sludge collection well 20, is provided with a wedge-shaped flow surface 15, a swirling sill 14, and a deceleration sill 16. The wedge-shaped flow surface 15 is located at the swirling sill 14 and guides the water flow. At the wellhead of the sewage collection well 20, the large stream of water supplied to the toilet bowl 10 by the water inlet 13 is swirled into the sewage collection well 20 by the swirling sill 14. It merges with a portion of the water that is blocked by the deceleration sill 16 and then flows into the sewage collection well 20 behind the water flow surface 12 to form a jet of flushing water. Another portion of the water flows is wedged into the sewage collection well 20 by the wedge surface 15 to form a vortex of flushing water. The jet of flushing water is tangentially rolled by the vortex of flushing water and rotates. Under the action of gravity, it pushes the sewage in the sewage collection well 20 out of the sewage pipe 30 for discharge.
[0035] The structure of each component of this utility model will be described below.
[0036] Reference Figure 1 , Figure 2 , Figures 5-7 As shown, the height of the toilet bowl 10 gradually decreases from the right rear clockwise to the left front, and gradually increases from the left front clockwise to the right rear. The height difference forms a clockwise water flow circulation path, which effectively increases the flow rate of water on the brush ring and improves the flushing effect.
[0037] Reference Figure 4 , Figure 5As shown, the horizontal inclination angle of the water surface 12 on the right side of the toilet bowl 10 is A, and the horizontal inclination angle of the water surface 12 on the left side of the toilet bowl 10 is B. Then A > B. The horizontal inclination angle of the water surface 12 on the right side is A = 15~20°, and the horizontal inclination angle of the water surface 12 on the left side is B = 5~10°. In this embodiment, the horizontal inclination angle of the water surface 12 on the right side is A = 17°, and the horizontal inclination angle of the water surface 12 on the left side is B = 5°. After the water flows through the water surface 12 to the lowest point in the middle, it is raised to the vortex sill 14, so that most of the water flow (i.e., the large stream of water) is blocked by the vortex sill 14 and guided into the sewage collection well 20.
[0038] Reference Figure 1 , Figure 4 As shown, a pressure guiding slope 21 is provided at the bottom of the sewage collection well 20. The pressure guiding slope 21 includes a convex arc annular surface 211 and a concave arc annular surface 212 that smoothly transition from top to bottom. It can narrow the bottom opening of the sewage collection well 20, so that the water flow at the bottom opening of the sewage collection well 20 is concentrated and smoothly guided to the sewage pipe 30, which not only makes the sewage discharge smoother, but also reduces the sewage discharge noise.
[0039] Reference Figures 1-4 As shown, an overflow port 60 is provided on the upper part of the basin edge 11 after the flushing surface 12. The function of the overflow port 60 is to discharge the rising water into the space behind the toilet after the toilet is blocked and the water in the toilet bowl cannot be discharged when the toilet is blocked. The water then flows to the floor drain on the floor and is discharged from the floor drain. However, the water on the flushing surface 12 is rapidly centrifugally swirling in the flushing surface 12 and is easily splashed out from the overflow port 60. Therefore, the deceleration step 16 set on the flushing surface 12 can slow down the flow rate of the water on the flushing surface 12 as it crosses the swirling step 14, and prevent the water on the flushing surface 12 from rising along the basin edge 11 and overflowing into the overflow port 60 under the centrifugal force when the toilet is flushing normally.
[0040] Reference Figures 1-4 , Figure 6 As shown, it also includes a recessed space 50, behind which is a rear wall plate 51. A socket pipe 40 connected to the end of the sewage pipe 30 is disposed in the recessed space 50. A reinforcing plate 70 with an L-shaped cross-section is disposed above the socket pipe 40. One end of the reinforcing plate 70 is integrally formed and connected to the outer wall of the upper part of the socket pipe 40, and the other end of the reinforcing plate 70 is integrally formed and connected to the inner side wall of the rear wall plate 51. The reinforcing plate 70 is used to connect the socket pipe 40 at the end of the sewage pipe 30 to the rear wall plate 51, thereby increasing the strength of the connection between the sewage pipe 30 and the socket pipe 40 and preventing breakage at the connection between the sewage pipe 30 and the socket pipe 40.
[0041] The working principle and specific implementation steps of this utility model are explained in detail below.
[0042] Reference Figure 6 , Figure 7As shown, the water supply from the inlet 13 to the toilet bowl 10 flows clockwise from the right rear of the sloping surface 12 to the left front, then splits into three streams: a large stream blocked by the vortex 14 and directed into the collection well 20; a stream blocked by the deceleration 16 and directed into the collection well; and a vortex stream cut into the collection well 20 by the wedge surface 15 and spiraling downwards along the well wall. This vortex stream can actuate the rotation of the stream formed by the water falling into the collection well 20, causing the large stream of water flowing into the collection well 20 to rotate at high speed. This serves the purpose of rotating and scrubbing the inner wall of the collection well 20, and also delays the speed at which the water in the collection well 20 enters the sewage pipe 30, so as to quickly raise the water level in the collection well 20 and realize that the water column in the collection well 20 falls under the action of gravity, pushing the sewage out of the sewage pipe 30 for discharge.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
