Implementation mode one
As shown in fig. 1, 2 and 5, the present invention provides a spray conduit 100 having a water inlet end 101 and a water outlet end 102, the spray conduit 100 having a spiral diversion surface 1 therein, a bus bar spirally moves from the water inlet end 101 to the water outlet end 102 around a vertical axis to form the spiral diversion surface 1, and a water flow enters from the water inlet end 101 and flows along the spiral diversion surface 1 to the water outlet end 102 under the action of its own gravity.
According to the jet water guide pipe 100, the spiral guide surface 1 is arranged, so that water flow can flow to the water outlet end 102 along the spiral guide surface 1 under the action of self gravity after entering from the water inlet end 101, the water flow makes spiral motion in the jet water guide pipe 100, and therefore, the rotation inertia and the impact force are generated, on one hand, the water outlet speed of the water flow is improved, and the energy of the water flow is increased; on the other hand, the water flow can be ensured to flow along the tangential direction of the spiral guide surface 1, the pipe resistance is small, the noise caused by the collision of the water flow and other parts in the jet water guide pipe 100 can be avoided, and the formation of the gathered rotating water flow is facilitated.
Specifically, the water discharge port 201 of the water tank 200 is connected to the spray guide pipe 300 through the spray water conduit 100, and is further discharged from the spray port 401 of the bedpan 400. The generatrix is a straight line arranged in a horizontal direction, i.e. the spiral deflector surface 1 is a flat spiral surface. The spiral guide surface 1 is formed as a flat spiral surface to be better communicated with the jet guide pipe 300, so that the water is jetted from the jet port 401 of the toilet bowl 400 in the axial direction of the jet port 401 through the jet guide pipe 300. The water inlet end 101 of the spray conduit 100 communicates with the water outlet 201 of the water tank 200, and the water outlet end 102 of the spray conduit 100 communicates with the spray port 401 of the bedpan 400. In the existing flush toilet, the speed of water flow discharged from the water tank 200 is low, and except for the flush toilet with a water pump, in other flush toilets, the water flow is conveyed from the water outlet 201 of the water tank 200 to the jet port 401 of the toilet bowl 400, which mainly converts gravitational potential energy into kinetic energy, so that the spiral guide surface 1 is set to the bottom surface of the jet water guide pipe 100 which is located at the lowest position in the vertical direction, so that the water flow falls on the spiral guide surface 1 by the gravity of the water flow after entering from the water inlet end 101 of the jet water guide pipe 100, and then flows along the spiral guide surface 1. Optionally, the generatrix is a concave curve substantially tangential to the horizontal direction, so that the spiral flow guide surface 1 is a spiral curved surface.
As shown in fig. 1, 2 and 5, in the embodiment of the present invention, the width of the spiral guide surface 1 in the generatrix direction (i.e., the horizontal direction) is gradually decreased along the spiral movement direction, so that the water flow is continuously pressurized while flowing along the spiral guide surface 1, thereby increasing the injection speed when the water flow is injected from the injection port 401 through the injection guide pipe 300.
Specifically, in order to ensure that the spiral flow guide surface 1 has a sufficient flow area, that is, the spiral flow guide surface 1 can receive the whole water flow and further flow along the spiral flow guide surface 1, the width of the spiral flow guide surface 1 is set according to the flow rate of the water tank 200 in each water outlet, the larger the flow rate is, the larger the width of the spiral flow guide surface 1 is, and the smaller the flow rate is otherwise. The passage sectional area of the spray guide duct 100 in the spiral movement direction is also gradually reduced.
In the embodiment of the invention, the width of the spiral guide surface 1 at the water inlet end 101 is 50mm-70mm, and the width of the spiral guide surface 1 at the water outlet end 102 is 40mm-55 mm. In this embodiment, the water tank 200 of the toilet bowl is a sink-type water tank, the width of the spiral guide surface 1 at the water inlet end 101 is 55mm to 70mm, preferably 65mm, and the width of the spiral guide surface 1 at the water outlet end 102 is 45mm to 55mm, preferably 50 mm. Referring to fig. 3 and 4, A, B, C, D cross-sectional areas of the four channels sequentially selected along the spiral movement direction on the jet water guiding pipe 100 are 2000mm respectively2、1800mm2、1400mm2、1200mm2. In another embodiment, the tank of the toilet is a high water tank, the width of the spiral guide surface 1 at the water inlet end 101 is 50mm-60mm, preferably 55mm, and the width of the spiral guide surface 1 at the water outlet end 102 is 40mm-50mm, preferably 45 mm.
As shown in fig. 1, 2 and 5, in the embodiment of the present invention, the injection water guiding pipe 100 further includes a web-shaped impact arc surface 2, the web-shaped impact arc surface 2 extends from the water inlet end 101 to the water outlet end 102 along a cylindrical spiral line parallel to the spiral flow guiding surface 1, and the web-shaped impact arc surface 2 is located on one side of the spiral flow guiding surface 1 away from the vertical axis. In order to avoid that a part of water flow is thrown to the outside of spiral flow guide surface 1 (i.e. one side of keeping away from vertical axis) under the effect of centrifugal force because speed increase at the in-process that flows along spiral flow guide surface 1, cause water flow to disperse and the movement track is disorderly, through set up abdomen towards arc surface 2 in the outside of spiral flow guide surface 1, can fall on abdomen towards arc surface 2 when a part of great water flow of speed is thrown to the outside of spiral flow guide surface 1 because centrifugal force, and then follow abdomen towards arc surface 2 and continue to make spiral motion. Specifically, when a moving point moves at a constant speed along a straight generatrix of the cylindrical surface, and the generatrix simultaneously rotates at a constant speed around the axis of the cylindrical surface, the locus of the moving point is a cylindrical spiral line. Therefore, the web punching arc surface 2 moves along a cylindrical spiral line parallel to the spiral flow guide surface 1, so that the water flow synchronously makes spiral motion with the water flow on the spiral flow guide surface 1 when flowing along the web punching arc surface 2. In this embodiment, abdomen towards arc surface 2 is located the face of cylinder at cylinder helix place, and abdomen towards arc surface 2 only has the radian in the direction of cylinder helix promptly and does not have the radian in vertical direction to can be connected better with injection stand pipe 300, and be favorable to abdomen towards can follow the axial blowout of injection port 401 under the guide of injection stand pipe 300 behind the rivers entering injection stand pipe 300 on the arc surface 2. Optionally, the web punch arc surface also has a curvature in the vertical direction.
As shown in fig. 1, 2 and 5, the injection conduit 100 further includes a first arc transition surface 3 and a second arc transition surface 4, one side of the spiral flow guiding surface 1 close to the vertical axis is connected to the outer wall surface of the toilet bowl 400, one side of the spiral flow guiding surface 1 far from the vertical axis is connected to one side of the abdomen impact arc surface 2 through the first arc transition surface 3, and the other side of the abdomen impact arc surface 2 is connected to the outer wall surface of the toilet bowl 400 through the second arc transition surface 4. Through setting up first circular arc transition surface 3 and second circular arc transition surface 4 for no matter that position is splashed when rivers get into from end 101 of intaking, homoenergetic is following current to spiral water conservancy diversion face 1 on, makes rivers gathering. The pipeline of the injection water guide pipe 100 is formed by the spiral flow guide surface 1, the abdominal impact arc surface 2, the first arc transition surface 3 and the second arc transition surface 4 which are matched with the outer wall surface of the bedpan 400 in a surrounding manner, so that the injection water guide pipe 100 and the bedpan 400 are conveniently formed integrally, and the problems of cracking, water leakage and the like can be avoided.
As shown in fig. 1, 3, 4 and 5, in the embodiment of the present invention, the width of the erosion arc surface 2 in the vertical direction gradually increases along the extending direction thereof, the arc length of the first arc transition surface 3 gradually decreases from the water inlet end 101 to the water outlet end 102, and the arc length of the second arc transition surface 4 gradually decreases from the water inlet end 101 to the connecting position between the erosion arc surface 2 and the outer wall surface of the bedpan 400. Because the speed of water flow entering from the water inlet end 101 is low, and the flow direction is uncertain, the area of the first arc transition surface 3 and the second arc transition surface 4 which can act on the water flow is large and the area of the belly impact arc surface 2 which can act on the water flow is small at the position close to the water inlet end 101, so that the water flow outside the spiral flow guide surface 1 can flow onto the spiral flow guide surface 1 along the first arc transition surface 3 and the second arc transition surface 4 under the action of self gravity; as the speed of the water flow is increased continuously, the water flow is more and more easy to flow to the erosion arc surface 2 along the first arc transition surface 3 under the action of centrifugal force, so that the area of the erosion arc surface 2 capable of acting on the water flow is also increased continuously, and the water flow with higher speed can flow along the erosion arc surface 2 to perform spiral motion.
Specifically, the web punching arc surface 2 has a first side 21, a second side 22, a third side 23 and a fourth side 24, the first side 21 is connected with the outer side of the spiral flow guide surface 1 through a first arc transition surface 3, the second side 22 is connected with the outer wall surface of the bedpan 400 through a second arc transition surface 4, the third side 23 is directly connected with the outer wall surface of the bedpan 400, and the fourth side 24 is connected with the injection guide pipe 300. The first arc transition surface 3 extends from the water inlet end 101 to the water outlet end 102 along a cylindrical spiral line parallel to the spiral guide surface 1 and is connected with the spray guide pipe 300. The second circular arc transition surface 4 has a first end connected to the water inlet end 101 of the jet conduit 100 and a second end connected to the junction of the second side 22 and the third side 23, and the arc length of the second circular arc transition surface 4 is gradually decreased from the first end to the second end thereof.
As shown in fig. 1, 5 and 6, the water inlet 101 is connected to the water outlet 201 of the water tank 200 through the connecting pipe 202, the height of the water inlet 101 is lower than that of the water outlet 201, the height of the water outlet 201 is higher than that of the water cover 402 in the toilet bowl 400, and the flow cross-sectional area of the connecting pipe 202 gradually decreases along the flow direction. The water outlet end 102 is communicated with the injection port 401 of the bedpan 400 through the injection guide pipe 300, and the height of the water outlet end 102 is not lower than that of the injection port 401.
The magnitude of the rotational inertia and the impulse generated by the water flow making the spiral motion in the injection water guide pipe 100 is closely related to the rotation angle of the generatrix and the height difference between the water inlet end 101 and the water outlet end 102 of the injection water guide pipe 100, and the larger the height difference is, the larger the rotation angle is, the larger the generated rotational inertia and impulse are. However, since the height of the water inlet end 101 of the spray conduit 100 is required to be lower than the height of the water discharge opening 201 of the tank 200, and the height of the water outlet end 102 of the spray conduit 100 cannot be lower than the height of the spray opening 401, the rotation angle of the bus bar is limited due to the installation space in the toilet bowl. In order to sufficiently increase the height of the discharge port 201 and smoothly discharge water, the discharge port 201 is provided at the side of the tank 200, and a certain rotation angle is required for the spiral guide surface 1 of the jet guide pipe 100, and if the discharge port 201 of the tank 200 is directly connected to the water inlet end 101 of the jet guide pipe 300 through the jet guide pipe 100, the size of the toilet bowl may be excessively increased. The injection water guide pipe 100 is communicated with the drain opening 201 through the connection pipe 202 so as to more reasonably arrange the injection water guide pipe 100, and in addition, the flow cross-sectional area of the connection pipe 202 is gradually reduced along the conveying direction of the water flow, so that the water flow enters the injection water guide pipe 100 after being pressurized.
In this embodiment, the distance (i.e., height difference) between the water inlet end 101 and the water outlet end 102 in the vertical direction is 50mm to 65mm, so that the water flow has a sufficiently large gravitational potential energy, and the water outlet speed of the water flow discharged from the water outlet end 102 meets the requirement. The rotation angle of the generatrix is 90-120 degrees, so that the water flow can generate enough rotation inertia to ensure that the water flow flows along the spiral flow guide surface 1.
Second embodiment
As shown in fig. 5 and 6, the present invention also provides a toilet bowl including a spray guide duct 100. The structure, operation principle and advantageous effects of the injection water conduit 100 in the present embodiment are the same as those of the injection water conduit 100 in the first embodiment, and are not described herein again. Specifically, the toilet further includes a toilet bowl 400, a water tank 200, a jet guide pipe 300 and a siphon 500, the toilet bowl 400 is communicated with the jet guide pipe 300 through a jet port 401, the toilet bowl 400 is communicated with the siphon 500 through a sewage discharge port 403, and the working principle of the toilet is the same as that of the prior art, and is not described herein again.
The above description is only a few embodiments of the present invention, and those skilled in the art can make various changes or modifications to the embodiments of the present invention according to the disclosure of the application document without departing from the spirit and scope of the present invention.
